[0042] In one embodiment, see Figure 4The glue dispensing device 3 includes a glue dispensing bracket 31, a glue-dipping swing arm assembly 32 and a glue supply device 33. The glue dispensing bracket 31 is arranged on the frame 1. The glue-dipping swing arm assembly 32 and the glue supply device 33 are both arranged on the glue dispensing bracket 31. The glue supply device 33 is used to provide glue liquid, and the glue-dipping swing arm assembly 32 is used to dip the glue liquid in the glue supply device 33 and apply it on the bracket belt. Specifically, the glue dispensing bracket 31 refers to a supporting component with a certain height, and its function is to support the glue supply device 33 and the glue-dipping swing arm assembly 32. The glue supply device 33 refers to a component that can provide glue liquid, and the glue-dipping swing arm assembly 32 refers to a component that can dip the glue liquid in the glue supply device 33 and apply it on the bracket belt. During the working process of the glue dispensing device 3, the bracket belt can be supported by the support slide 21, and the glue-dipping swing arm assembly 32 dips the glue liquid in the glue supply device 33 and then applies it to the crystal bonding position on the bracket belt, making the glue dispensing operation more convenient and quick.

[0043] In one embodiment, see Figure 6 The glue supply device 33 includes a glue disk 334, a glue supply support seat 331, a glue disk driving mechanism 332 and a scraper assembly 333. The glue supply support seat 331 is arranged on the glue dispensing bracket 31. The glue disk 334 is rotatably arranged on the glue supply support seat 331 and is used to contain glue liquid.

The glue disc 334 refers to a disc-shaped component with a certain storage space. The glue disc 334 can have a depression of a certain depth to form the above-mentioned storage space. The opening of the glue disc 334 is generally set upward to prevent the glue contained in the glue disc 334 from leaking out. The glue disc 334 is rotatably arranged on the glue supply support seat 331, which means that the glue disc 334 can rotate relative to the glue supply support seat 331, wherein the rotation direction of the glue disc 334 is generally horizontal; the glue disc 334 can be connected to the glue supply support seat 331 through a rotating shaft, or a plurality of rollers arranged around the glue disc 334 can be arranged on the glue supply support seat 331, so that the glue disc 334 can be supported and rotated at the same time. The glue disk 334 may be disposed below the outlet of the glue container so that the glue can flow into the glue disk 334 during operation, thereby replenishing the glue in the glue disk 334 .

In this way, when the glue disc 334 rotates, the scraper assembly 333 will scrape the glue liquid in the glue disc 334.

[0046] During the operation of the glue supply device 33, the glue disc 334 is driven to rotate by the glue disc driving mechanism 332, so that a relative movement is generated between the glue disc 334 and the scraper assembly 333, so that the scraper assembly 333 scrapes the glue liquid in the glue disc 334, thereby ensuring that the depth of the glue liquid after the scraper assembly 333 scrapes remains constant. At this time, the glue-dipping swing arm assembly 32 can pick up glue liquid in the area after the scraper assembly 333 scrapes, ensuring that the amount of glue liquid picked up by the glue-dipping swing arm assembly 32 is constant each time, thereby ensuring the consistency of the glue dispensing amount and improving the quality of the product.

[0049] In a specific embodiment, Figure 6As shown, the glue disk power unit 3321 adopts a driving motor, and a first gear is arranged at the second end of the rotating shaft of the glue disk 334. The driving end of the driving motor is connected to the second gear, and the first gear and the second gear are meshed with each other. The glue disk 334 and the connecting shaft of the glue disk 334 can be driven to rotate by the rotation of the driving motor.
