According to the production process, each process point has a corresponding quality control point, and each quality control point also reflects the operation of the hollow equipment.
1. Film removal station: Remove LOW-E according to the sealing depth of the second layer of structural adhesive (polysulfide adhesive). The main purpose is to control the width of the film removal. From the beginning of the film removal to the end of the film removal, the width error of the film removal should be within 0.5mm, otherwise the upper frame station will cause problems such as lamination width and whitening. The second is to avoid problems such as unclean film removal, scratching the film surface when touching, and removing the glass from the film removal wheel.
2. Cleaning and drying station: When cleaning and drying glass, because it uses a brush to spray water to roll and scrub the glass, there are often scratches and water marks on the film surface, and air knives often appear in the air-drying section of the rear drive fan. Print, drive wheel print, belt print and scratches and other quality problems. The above problems should be adjusted and solved in time.
3. Observation and inspection station: This station is a position for checking the quality of film removal and cleaning. There are special quality inspection boxes. The quality problems of film removal and cleaning should be found as soon as possible. And complete the frame work at the observation platform.
4. Spacer frame production: According to the spacer bar specification, material and size required by the process card, the insulating glass spacer bar is processed and produced. In the process of frame making, quality problems such as inaccurate frame making, rounded corners, smudges on the surface of the spacer, improper connectors, deformation of the spacer interface, and large saw burrs are prone to occur.
5. Spacer filling and drying machine: This process is to fill the spacer with desiccant (molecular sieve). Generally, within 15 minutes, the spacer bar filled with desiccant is completed to complete the insulating glass sheet to prevent the molecular sieve from failing. During the filling and flushing period, there will be quality hidden dangers such as dissatisfaction with the filling and flushing, the glue plugging at the filling and flushing mouth is not tight, and the spacer strips are deformed by the flushing machine.
6. Coating butyl rubber: Pay attention to the quality of butyl rubber coating on both sides of the spacer. Generally, the quality of the laminating machine is used to judge the coating condition of the butyl rubber machine. After lamination, the butyl rubber is used. The width should be greater than 5mm. When coating with a butyl glue machine, attention should also be paid to the waves, broken glue and the residual glue on the front of the spacer bar not to be combined into the insulating glass.
7. Upper frame station: This process is carried out together with observation and inspection, and the qualified glass and spacer bars should be installed together. During the period, pay attention to the lamination and whitening of the frame. If there is a problem, it should be reported to the first few stations in time, and immediately corrected to prevent the occurrence of substandard products.
8. Joining: Join two or more single pieces of glass together with spacers. After the incoming materials that have been strictly inspected in the past are laminated, there will still be quality hidden dangers caused by the lamination station, such as deformation of the spacer after lamination, dislocation of lamination, width of butyl glue after lamination is less than 5mm, butyl glue virtual A series of quality problems such as connection, panel scratches, etc. It is necessary to adjust the equipment in time according to the actual situation after assembling, so that it can meet the processing requirements of each size of glass.
9. Edge sealing process: After carefully checking the lamination, seal the edges and apply the second sealant. According to the proportion provided by the glue factory, the proportion and mixing are carried out to meet the specified use requirements; the operation is carried out according to the glue type and sealing depth required by the process card, and the uniformity of mixing glue, the air line of sealing glue, the sealing glue wave, etc. must be controlled. Quality issues.
