Description

Technical Field

[0001] The invention relates to the technical field of glass fiber mesh coating operations, and in particular to a glass fiber mesh coating operation control system. Background Art

[0002] In the production process of glass fiber mesh, coating operation is a key link. Factors such as coating uniformity, material dosage control and mesh transmission stability directly affect the quality and performance of the product. Traditional coating operations often rely on manual experience for control, and there are problems such as uneven coating, low efficiency and unstable quality. With the development of automation technology, a system that can accurately control each link of the coating operation is needed to improve production efficiency and product quality.

[0003] For example, the Chinese patent publication number CN1857792A discloses a post-processing production method and equipment for glass fiber mesh cloth for high-speed grinding wheels, including: firstly winding the mesh cloth to be processed on a cloth-laying roller, and then performing a dipping treatment; the mesh cloth after dipping enters a glue squeezing roller device to squeeze glue, and then enters a drying tunnel for secondary drying; the mesh cloth after drying is expanded by an expansion mechanism, and then rolled up on a cloth-collecting roller; the adopted equipment is composed of a cloth-laying roller, a dipping mechanism, a glue squeezing roller, drying tunnels I and II, an expansion mechanism, a cloth-collecting mechanism, and a control mechanism, the cloth-laying roller is connected to the dipping mechanism, the glue squeezing roller is arranged on the dipping mechanism, two vertical drying tunnels are arranged above the glue squeezing roller, the expansion mechanism is arranged at the outlet of the drying tunnel, and the winding mechanism is connected to the expansion mechanism; since vertical drying is adopted and multiple dryings are arranged in the drying tunnel, it is beneficial to the surface physical and chemical reaction of the mesh cloth; since the mesh cloth after drying is expanded, the yarn of the mesh cloth forms a certain prestress, and the mesh cloth is flat at the same time.

[0004] The above existing technologies still have the following problems: 1. Each process in the glass fiber mesh coating operation is not monitored and analyzed, that is, the mesh transmission process, coating material supply process, coating execution process and coating uniformity adjustment process are not monitored and analyzed respectively, and the mesh tension, coating material supply, coating material temperature and coating uniformity cannot be accurately controlled, and the coating quality of the glass fiber mesh cannot be significantly improved, which increases coating defects and reduces product consistency and reliability.

[0005] 2. Failure to comprehensively analyze whether the tension control is reasonable based on the tension control uniformity and tension control compliance during the mesh transmission process, and failure to make timely adjustments when the tension control is unreasonable will have a serious impact on product quality, production efficiency and equipment, causing huge losses to the company.

[0006] 3. The coating information corresponding to each historical coating operation is not combined to determine whether the amount of coating material currently stored in the storage tank is sufficient, and the usage of coating materials cannot be accurately estimated. In the production process, it may be suddenly discovered that the coating material is insufficient, causing the production line to stop unexpectedly, seriously affecting the production progress.

[0007] 4. The coating uniformity of the glass fiber mesh was not adjusted according to the coating effect of the glass fiber mesh, and the scraper pressure was not repeatedly fine-tuned according to the adjusted mesh coating effect, which reduced the accuracy of the scraper pressure confirmation in the coating uniformity adjustment area and failed to achieve the best coating uniformity adjustment effect. Summary of the invention

[0008] In view of this, in order to solve the problems raised in the above background technology, a glass fiber mesh coating operation control system is now proposed.

[0010] The coating material supply module is used to extract the material liquid level currently stored in the target storage tank and the expected material liquid level drop value corresponding to the target glass fiber mesh, and to extract the coating information corresponding to each historical coating operation, to determine whether the amount of coating material currently stored in the target storage tank is sufficient, and if not, to supply coating material.

[0011] The coating execution module is used to collect the material spraying grayscale images corresponding to each coating nozzle in the coating execution area when the target glass fiber mesh is transmitted to the coating execution area, and determine whether there is an abnormal material spraying state problem of the coating nozzle in the coating execution area. If so, collect the current temperature of the coating material in the target storage tank and adjust the temperature of the coating material in the target storage tank.

[0012] The coating uniformity adjustment module is used to collect the coating material thickness corresponding to each detection point on the target glass fiber mesh after coating is executed, and evaluate whether the coating effect corresponding to the target glass fiber mesh meets the standard. If not, the pressure of the scraper in the coating uniformity adjustment area is extracted, and the coating uniformity of the target glass fiber mesh is adjusted.

[0013] The database is used to store the appropriate speed difference of the conveyor roller corresponding to the rationality of each tension control, store the required compensation level corresponding to the estimated accuracy deviation of the unit material level drop, store the gray value interval corresponding to the normal material spraying state corresponding to the coating nozzle, store the appropriate heating temperature of the coating material corresponding to the abnormal index of the spraying state of each material, and store the required pressure increase value of the scraper corresponding to the unit coating effect deviation.

[0014] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: (1) The present invention monitors and analyzes each process in the glass fiber mesh coating operation, that is, the mesh transmission process, coating material supply process, coating execution process and coating uniformity adjustment process are monitored and analyzed respectively, so as to accurately control the mesh tension, coating material supply, coating material temperature and coating uniformity, thereby significantly improving the coating quality of the glass fiber mesh, reducing coating defects, and improving the consistency and reliability of the product.

[0015] (2) The present invention comprehensively analyzes whether the tension control is reasonable based on the tension control uniformity and tension control compliance during the mesh transmission process, and makes timely adjustments when the tension control is unreasonable, thereby avoiding serious impact on product quality, production efficiency and equipment, thereby avoiding huge losses to the enterprise.

[0016] (3) The present invention determines whether the amount of coating material currently stored in the storage tank is sufficient by combining the expected material level drop values ​​corresponding to each historical coating operation, the storage tank level before coating, and the storage tank level after coating. This can accurately estimate the amount of coating material used, avoid the sudden discovery of insufficient coating material during the production process, which may lead to unexpected shutdown of the production line, and ensure that the production progress is not affected.

[0017] (4) The present invention adjusts the coating uniformity of the glass fiber mesh according to the coating effect of the glass fiber mesh, and repeatedly fine-tunes the pressure of the scraper according to the adjusted mesh coating effect, thereby improving the accuracy of confirming the scraper pressure in the coating uniformity adjustment area and helping to achieve the best coating uniformity adjustment effect.
