Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module production technology and relates to a photovoltaic module AB glue flow measurement device. Background Technology

[0002] Photovoltaic modules are the core component of photovoltaic power generation systems. They achieve photoelectric conversion by encapsulating photovoltaic cells. The production of photovoltaic modules involves using a packaging process to manufacture solar cells into devices that can generate electricity independently. During the packaging process, AB glue equipment is used to apply glue to ensure the waterproof performance of the module's interior.

[0003] For example, Chinese patent literature discloses a potting compound device for the production of photovoltaic junction boxes [Application No.: 202321579743.X; Authorization Announcement No.: CN220027587U], which includes a fixed base, a sealing mechanism on the top of the fixed base, a drying component on the outside of the fixed base, a mounting frame fixedly connected to the fixed base, a variable speed motor fixedly connected inside the mounting frame, a lead screw fixedly connected to the output end of the variable speed motor, a slider threadedly connected to the outside of the lead screw, and an electric push rod fixedly connected to the bottom of the slider.

[0004] The aforementioned potting compound device for photovoltaic junction box production facilitates potting compound treatment for photovoltaic junction boxes, reducing the user's workload. However, it cannot effectively monitor for insufficient compound after potting. Once equipment malfunctions and leakage occurs, the A / B compound ratio of the modules cannot be tracked during the production process, and batch problems can only be detected by personnel in the testing and cleaning area. Defective modules produced in this area have long rework times and are prone to customer complaints due to poor appearance. Existing A / B compound control the amount of compound by pump speed, but cannot identify the compound ratio, resulting in insufficient or uneven compound in the junction box, and the liquid cannot cure. Excessive use of the compound ratio cannot be detected immediately, and the cause can only be found through random checks or on-line personnel. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a photovoltaic module AB glue flow measurement device with glue filling monitoring function, which avoids batch defective production due to glue overflow, reduces rework costs, improves product yield, enhances the stability of single-line test line, and avoids line blockage caused by abnormalities.

[0006] The objective of this utility model can be achieved through the following technical solution: A photovoltaic module AB glue flow measurement device, comprising an A glue barrel and a B glue barrel, the bottom of both the A glue barrel and the B glue barrel being fixedly connected to a first conveying pipe, the bottom of the first conveying pipe being connected to a pneumatic screw pump, the discharge end of the pneumatic screw pump being connected to a second conveying pipe, a pneumatic pressure and volumetric flow meter assembly being installed on the side of the second conveying pipe away from the pneumatic screw pump, an AB glue mixing motor assembly being installed and connected between the two pneumatic pressure and volumetric flow meter assemblies, and an AB glue spiral mixing pipe being installed and connected to the discharge end of the AB glue mixing motor assembly.

[0007] This photovoltaic module AB glue flow measurement device mainly consists of a first feeding pipe, a second feeding pipe, an AB glue mixing motor assembly, an air pressure and volumetric flow meter assembly, an air pressure screw pump, and a monitoring alarm. Through the first feeding pipe, the second feeding pipe, the AB glue mixing motor assembly, the air pressure and volumetric flow meter assembly, the air pressure screw pump, and the monitoring alarm, it provides glue filling monitoring functionality, preventing batch defects caused by glue overflow, reducing rework costs, improving product yield, enhancing the stability of the single-line testing line, and preventing line blockage due to abnormalities.

In practical applications, by setting up stirring blades, the stirring motors can drive them to rotate and stir the adhesive in the A and B adhesive barrels, preventing solidification that could affect flow.

[0009] In the aforementioned photovoltaic module AB adhesive flow measurement device, both the top of the A adhesive barrel and the B adhesive barrel are fixedly connected to a feed hopper, and a fixed bracket is installed on the outside of the pneumatic screw pump. In practical applications, the feed hopper facilitates the addition of adhesive to the A and B adhesive barrels, and the fixed bracket facilitates the support and installation of the pneumatic screw pump.

[0010] In the aforementioned photovoltaic module AB glue flow meter, cleaning pipes are installed and connected to the feed ends on both sides of the AB glue mixing motor assembly, and a glue tube cleaning tank is installed and connected to the top of the cleaning pipes. In practical applications, by setting up the glue tube cleaning tank, cleaning water can flow out through the cleaning pipes to clean the AB glue mixing motor assembly and the interior of the AB glue spiral mixing tube.

[0011] In the aforementioned photovoltaic module AB glue flow measurement device, the output end of the pressure and volumetric flow meter assembly is fixedly connected to a connecting wire, and the other end of the connecting wire is electrically connected to a monitoring alarm. In practical applications, the pressure and volumetric flow meter assembly contains a microcontroller, which can control the monitoring alarm to activate and alert personnel when the glue flow rate is greater than or less than a preset value.

[0012] In the aforementioned photovoltaic module AB glue flow meter, the outlet end of the AB glue spiral mixing tube is equipped with a mixing outlet. In practical applications, by providing the mixing outlet, the glue inside the AB glue spiral mixing tube can be conveniently injected into the junction box.

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1 As shown, the photovoltaic module AB glue flow measurement device includes an A glue tank 1 and a B glue tank 2. The bottom of both the A glue tank 1 and the B glue tank 2 are fixedly connected to a first conveying pipe 5. A pneumatic screw pump 12 is installed and connected to the bottom of the first conveying pipe 5. The discharge end of the pneumatic screw pump 12 is connected to a second conveying pipe 7. A pneumatic pressure and volumetric flow meter assembly 10 is installed on the side of the second conveying pipe 7 away from the pneumatic screw pump 12. An AB glue mixing motor assembly 8 is installed and connected between the two pneumatic pressure and volumetric flow meter assemblies 10. An AB glue spiral mixing pipe 9 is installed and connected to the discharge end of the AB glue mixing motor assembly 8.

[0018] To elaborate further, both the top of rubber material tank 1 (A) and rubber material tank 2 (B) are equipped with a stirring motor 3, and the output shaft of the stirring motor 3 is fixedly fitted with a stirring blade 4. The top of both rubber material tank 1 and rubber material tank 2 are fixedly connected to a feed hopper 13, and a fixed bracket 6 is installed on the outside of the pneumatic screw pump 12.

[0019] The AB glue mixing motor assembly 8 has cleaning pipes 11 connected to the feed ends on both sides, and a glue cleaning tank 16 is connected to the top of the cleaning pipes 11. The output end of the air pressure and volumetric flow meter assembly 10 is fixedly connected to a connecting wire 14, and the other end of the connecting wire 14 is electrically connected to a monitoring alarm 15. The discharge end of the AB glue spiral mixing tube 9 is equipped with a mixing discharge port.

[0020] During operation, the two pneumatic screw pumps 12, once powered on, draw out the A and B adhesives from the A and B adhesive barrels 1 and 2 through the first conveying pipe 5, respectively. The adhesives then flow into the second conveying pipes 7 on both sides. The pneumatic and volumetric flow meter components 10 on both sides monitor the A and B adhesives in the second conveying pipes 7. By using algorithms such as pneumatic pressure fluctuation and volumetric usage, the amount of adhesive flowing through the flow meter is monitored. This allows the determination of the amount of A and B adhesives used in the junction box of the device. By monitoring the pneumatic pressure fluctuation and volumetric usage of the differential pressure flow meter within a tolerance range of 0.8 MPa ± 0.05 MPa, the device provides a real-time monitoring function for the amount of AB adhesive flowing out of the flow meter during the process. This ensures that the AB adhesive dispensing machine provides early warning and supervision for any over- or under-limit conditions throughout the entire process, avoiding waste of materials and preventing the production of reworked components due to batch abnormalities.
