Abstract
Description
Technical Field
[0001] The invention relates to the technical field of glue pouring machinery, in particular to a high-frequency precision two-component glue mixer and a glue coating method thereof. Background Art
[0002] In the current photovoltaic module manufacturing industry, the spraying process of frame sealant plays a vital role. It is not only related to the sealing performance and long-term durability of the module, but also directly affects production efficiency and cost control. Traditionally, single-component sealants are mostly used in this link. However, this type of sealant has become a bottleneck restricting the improvement of production efficiency due to its long curing time. Every time the module is assembled on the assembly line and off the line, it has to go through a relatively long inventory waiting period to ensure that the sealant is completely cured, which undoubtedly increases the product's time in the factory and the overall cost. This problem is particularly prominent, especially in the context of the continued growth in demand for photovoltaic modules and the urgent need to expand production capacity. Summary of the invention

[0006] Furthermore, the outlets of the first metering cylinder and the second metering cylinder are connected to the inlet on one side of the glue mixing valve through a one-way valve, and the outlets of the third metering cylinder and the fourth metering cylinder are connected to the inlet on the other side of the glue mixing valve through a one-way valve.
[0007] Furthermore, a switch valve is installed between the glue mixing valve and the first metering cylinder and the second metering cylinder, and a switch valve is installed between the glue mixing valve and the third metering cylinder and the fourth metering cylinder.
[0008] Furthermore, the hydraulic cylinders of the first metering cylinder, the second metering cylinder, the third metering cylinder and the fourth metering cylinder are respectively connected to their corresponding hydraulic solenoid reversing valves, the two hydraulic solenoid reversing valves of the first metering cylinder and the second metering cylinder are connected to the same hydraulic servo system, and the two hydraulic solenoid reversing valves of the third metering cylinder and the fourth metering cylinder are connected to another hydraulic servo system.
[0009] Furthermore, the first delivery pump and the second delivery pump are reciprocating plunger pumps or piston pumps.
[0010] A glue coating method based on a high-frequency precision two-component glue mixer comprises the following steps: Step 1). Inject glue A into the first glue tank and inject glue B into the second glue tank; Step 2).

Inject glue A in the second metering cylinder and glue B in the fourth metering cylinder into the glue mixing valve at the same time, and spray them onto the photovoltaic module through the glue mixing valve. At the same time, inject glue A into the first metering cylinder through the first delivery pump, and inject glue B into the third metering cylinder through the second delivery pump; Step 5). Repeat step 3 while injecting glue A into the second metering cylinder through the first delivery pump, and injecting glue B into the fourth metering cylinder through the second delivery pump; Step 6). Repeat steps 3 to 5 until the gluing process of the photovoltaic module is completed.
[0011] Compared with the prior art, the present invention has the following outstanding beneficial effects: The present invention has two sets of glue replenishing mechanisms, namely a first glue replenishing mechanism and a second glue replenishing mechanism. Each set of glue replenishing mechanisms is respectively provided with two metering cylinders.
