中空玻璃生产线90度边有波浪？生产时常见问题排查指南

　　Is there a wave on the 90 degree edge of the insulated glass production line? Guidelines for troubleshooting common problems during production

　　在中空玻璃生产线的封胶工序中，90度边出现波浪纹是困扰不少生产企业的常见问题。这看似不起眼的波纹，不仅拉低了中空玻璃的外观质感，更暗藏质量隐患——可能导致胶层贴合不紧密，直接降低产品密封性能，增加后期渗水、起雾的风险，严重时还会影响产品合格率，耽误生产进度。很多生产线操作人员遇到这类问题时容易盲目排查，反而浪费时间。今天就专门聚焦中空玻璃生产线，给大家梳理封胶线90度边出波浪的核心原因，方便大家直接对照排查，快速解决问题。

　　In the sealing process of insulated glass production lines, the occurrence of wavy lines on the 90 degree edge is a common problem that troubles many manufacturing enterprises. This seemingly inconspicuous ripple not only lowers the appearance texture of the insulated glass, but also hides quality hazards - it may cause the adhesive layer to not fit tightly, directly reducing the sealing performance of the product, increasing the risk of water leakage and fogging in the later stage, and in severe cases, affecting the product qualification rate and delaying production progress. Many production line operators are prone to blind troubleshooting when encountering such problems, which actually wastes time. Today, we will specifically focus on the production line of insulating glass, and sort out the core reasons for the waves on the 90 degree edge of the sealing line, making it convenient for everyone to directly compare and investigate, and quickly solve problems.

　　第一个核心原因：胶嘴选型或状态出问题，这是最容易排查的关键点。在中空玻璃生产线的封胶环节，胶嘴是直接影响涂胶成型的核心部件。首先要核对胶嘴型号是否匹配当前生产需求，胶嘴口径太大或太小，都会导致出胶量不均匀，尤其是90度转角处，胶层无法平稳过渡，很容易形成波浪。其次要检查胶嘴的使用状态，长期在生产线上使用后，胶嘴难免会出现磨损、变形，或者被胶水残渣堵塞，这些都会破坏出胶的顺畅性。另外，胶嘴与玻璃的距离调节不当也会引发问题，距离太远，胶水无法精准贴合玻璃表面；距离太近，又会产生过大阻力，导致涂胶轨迹偏移，最终形成波浪纹。

　　The first core reason is that there is a problem with the selection or condition of the rubber nozzle, which is the easiest key point to troubleshoot. In the sealing process of the insulated glass production line, the glue nozzle is the core component that directly affects the coating and molding. Firstly, it is necessary to verify whether the nozzle model matches the current production requirements. If the nozzle diameter is too large or too small, it can lead to uneven dispensing, especially at 90 degree corners where the adhesive layer cannot transition smoothly and can easily form waves. Secondly, it is necessary to check the usage status of the glue nozzle. After long-term use on the production line, the glue nozzle is inevitably worn, deformed, or blocked by glue residue, which will damage the smoothness of the glue dispensing process. In addition, improper adjustment of the distance between the glue nozzle and the glass can also cause problems. If the distance is too far, the glue cannot accurately adhere to the surface of the glass; If the distance is too close, it will generate excessive resistance, causing the glue trajectory to deviate and ultimately forming wavy patterns.

　　第二个核心原因：涂胶参数设置不当，这是生产线中最易忽视的关键因素。封胶线的涂胶速度和压力是影响成型效果的核心参数，两者没匹配好，90度边出波浪的概率会大幅增加。如果涂胶速度过快，胶水在玻璃表面还没来得及均匀铺开，就被胶枪快速拖动，尤其是90度转角处，胶层尚未成型就发生位移，很容易出现波纹；要是涂胶压力不稳定，时大时小，会直接导致出胶量忽多忽少，转角处胶层衔接不畅，厚的地方堆积、薄的地方凹陷，形成明显的波浪。很多生产线操作人员只关注胶水温度参数，却忽略了速度和压力的适配，这也是常见的踩坑点。

　　The second core reason is improper setting of adhesive parameters, which is the most easily overlooked key factor in the production line. The coating speed and pressure of the sealing line are the core parameters that affect the forming effect. If the two are not matched well, the probability of waves appearing on the 90 degree edge will increase significantly. If the glue application speed is too fast and the glue has not been evenly spread on the glass surface, it will be quickly dragged by the glue gun, especially at the 90 degree corner where the glue layer will shift before it is formed, making it easy to produce ripples; If the adhesive pressure is unstable, sometimes large and sometimes small, it will directly lead to fluctuating adhesive output, poor connection of the adhesive layer at corners, accumulation in thick areas, and depression in thin areas, forming obvious waves. Many production line operators only focus on the temperature parameters of the glue, but neglect the adaptation of speed and pressure, which is also a common pitfall.

　　第三个核心原因：胶水状态不符合生产要求，直接影响涂胶平整度。封胶用的丁基胶、结构胶等材料，其状态是中空玻璃生产线封胶质量的基础保障。如果胶水粘度不合适，太稀会导致涂胶时出现流挂不均的情况，太稠则流动性差，难以在玻璃表面顺畅铺开，这两种情况在90度转角处都会明显显现出波浪。另外，胶水在储存或生产线使用过程中，如果操作不当导致内部混入气泡、杂质，涂胶时这些异物会破坏胶层的平整度，而转角处胶层受力发生变化，波浪问题会更加突出。建议生产线在使用胶水前，先简单检查其外观和流动性，确认无异常后再投入生产。

　　The third core reason is that the adhesive state does not meet the production requirements, which directly affects the smoothness of the adhesive coating. The state of materials such as butyl rubber and structural adhesive used for sealing is the basic guarantee for the sealing quality of the insulating glass production line. If the viscosity of the glue is not suitable, being too thin can lead to uneven flow when applying the glue, while being too thick can result in poor fluidity and difficulty spreading smoothly on the glass surface. Both situations will show obvious waves at a 90 degree corner. In addition, if the glue is stored or used on the production line improperly, bubbles and impurities may be mixed inside. These foreign objects will damage the flatness of the adhesive layer during coating, and the stress on the adhesive layer at corners will change, making wave problems more prominent. It is recommended that the production line conduct a brief inspection of the appearance and fluidity of the glue before using it, and confirm that there are no abnormalities before putting it into production.

　　第四个核心原因：设备运行精度不足，生产线核心部件状态影响成型效果。中空玻璃生产线的封胶线属于精密设备，核心部件的磨损或松动会直接拉低运行精度。比如封胶线的导轨、丝杠出现磨损，或者定位装置松动，会导致胶枪在移动过程中运行不平稳，尤其是在90度转角时容易出现偏移、抖动，涂胶轨迹自然就变成了波浪状。还有玻璃定位环节的问题，如果生产线的玻璃输送、定位装置出现偏差，会导致涂胶路径偏离预设轨迹，90度边的胶层无法按照标准平整成型，进而出现波浪纹。

　　The fourth core reason is insufficient precision in equipment operation, and the status of core components on the production line affects the molding effect. The sealing line of the insulated glass production line is a precision equipment, and the wear or looseness of the core components will directly lower the operating accuracy. For example, if the guide rail and screw of the sealing line are worn, or if the positioning device is loose, it will cause the glue gun to run unevenly during movement, especially at a 90 degree angle, it is easy to deviate and shake, and the glue coating trajectory will naturally become wavy. There is also an issue with the glass positioning process. If there are deviations in the glass conveying and positioning devices on the production line, it can cause the glue path to deviate from the preset trajectory, and the 90 degree edge of the glue layer cannot be formed smoothly according to the standard, resulting in wavy patterns.

　　第五个核心原因：作业环境温度影响，这是生产线中的“隐形干扰因素”。环境温度对胶水性能和涂胶效果的影响很容易被忽视，但却是导致90度边出波浪的重要原因之一。如果生产线封胶区域的温度太低，胶水的流动性会变差，涂胶时无法在玻璃表面顺畅铺开，胶层在转角处堆积就会形成波浪；要是温度太高，胶水粘度会下降，涂胶后容易出现流挂现象，同样会破坏90度边的成型效果。建议生产线将封胶区域的温度控制在15-30℃的适宜范围，同时避免温度波动过大，减少环境对封胶效果的影响。

　　The fifth core reason is the influence of operating environment temperature, which is a "hidden interference factor" in the production line. The influence of environmental temperature on the performance and coating effect of glue is easily overlooked, but it is one of the important reasons for the occurrence of waves at 90 degrees. If the temperature in the sealing area of the production line is too low, the fluidity of the glue will deteriorate, and it will not be able to spread smoothly on the glass surface when applying glue. The glue layer will accumulate at the corners and form waves; If the temperature is too high, the viscosity of the glue will decrease, and it is easy to cause sagging after coating, which will also damage the forming effect of the 90 degree edge. It is recommended to control the temperature in the sealing area of the production line within a suitable range of 15-30 ℃, while avoiding excessive temperature fluctuations and reducing the impact of the environment on the sealing effect.

　　给生产线操作人员分享一个高效排查顺序，不用盲目找问题：第一步优先检查胶嘴，确认型号匹配、无磨损堵塞，同时调好胶嘴与玻璃的距离；第二步调试涂胶参数，先适当降低涂胶速度，稳定涂胶压力，观察转角成型效果；第三步检查胶水状态，查看粘度是否合适、有无气泡杂质；第四步排查设备运行情况，检查导轨、定位装置是否松动磨损，校准玻璃定位精度；最后检查环境温度，确保符合作业要求。按这个顺序排查，基本能快速定位问题并解决，减少生产线停机时间。

　　Share an efficient troubleshooting sequence with production line operators, without blindly looking for problems: the first step is to prioritize checking the rubber nozzle, confirm that the model matches, there is no wear or blockage, and adjust the distance between the rubber nozzle and the glass; The second step is to debug the glue parameters. First, reduce the glue speed appropriately, stabilize the glue pressure, and observe the corner forming effect; The third step is to check the status of the glue, whether the viscosity is appropriate, and whether there are any bubbles or impurities; The fourth step is to investigate the operation of the equipment, check whether the guide rail and positioning device are loose and worn, and calibrate the glass positioning accuracy; Finally, check the ambient temperature to ensure compliance with the job requirements. By following this sequence of troubleshooting, problems can be quickly identified and resolved, reducing downtime on the production line.

　　总结下来，中空玻璃生产线中，封胶线90度边出现波浪的核心原因就集中在胶嘴、涂胶参数、胶水、设备、环境这五个方面。对生产企业来说，只要在生产线运行过程中，做好封胶设备的日常维护、规范胶水的储存和使用、精准设置涂胶参数，就能有效避免这类问题。掌握这些原因和排查方法，能帮助操作人员快速解决故障，保障产品质量稳定。如果排查后仍无法解决，建议联系封胶线设备厂家的专业技术人员，对生产线设备进行全面校准和检修。

　　In summary, the core reasons for the occurrence of waves on the 90 degree edge of the sealing line in the production line of insulated glass are concentrated in five aspects: the glue nozzle, glue parameters, glue, equipment, and environment. For production enterprises, as long as they do a good job in the daily maintenance of sealing equipment, standardize the storage and use of glue, and accurately set the glue parameters during the operation of the production line, they can effectively avoid such problems. Mastering these reasons and troubleshooting methods can help operators quickly solve faults and ensure stable product quality. If the problem still cannot be solved after investigation, it is recommended to contact the professional technical personnel of the sealing line equipment manufacturer to conduct comprehensive calibration and maintenance of the production line equipment.
