[0034] Further, please refer to the figure, which also includes a lifting mechanism 5 for driving the coating box 2 to move up and down, and two sets of lifting mechanisms 5 are symmetrically arranged on both sides of the coating box 2. The lifting mechanism 5 includes a column 51, a chute 52, a lifting block 53, a connecting block 54, a second servo motor 55, and a second threaded rod 56. The column 51 is arranged on the side of the coating box 2, and the position of the column 51 is fixed. The chute 52 is longitudinally opened in the column 51, and the lifting block 53 is slidably connected in the column 51 through the chute 52, and the lifting block 53 slides smoothly in the column 51.

The lifting block 53 drives the coating box 2 to move upward through the connecting block 54. At this time, the coating box 2 is away from the coating station 1, which facilitates the substrate to pass between the coating station 1 and the coating box 2. The substrate is pulled by the traction mechanism to move, and the coating box 2 moves downward to approach the coating station 1.

[0036] The first servo motor 37 is started, and the first servo motor 37 drives the first threaded rod 38 to rotate, thereby driving the moving block 33 to move along the length direction of the first threaded rod 38. The moving block 33 moves smoothly under the sliding limit of the two sets of fixed rods 32. At the same time, the moving block 33 drives the multiple sets of heating tubes 35 to move synchronously through the moving plate 34. The heating tubes 35 move in the coating box 2. The electric heating wires in the heating tubes 35 are energized to heat the adhesive. At the same time, the heating tubes 35 stir the adhesive while moving. At this time, the temperature sensor 36 senses the temperature of the adhesive in the coating box 2, so as to control the heating power of the electric heating wire in real time through the electrical box 6 to balance the temperature of the adhesive in the coating box 2. At the same time, when the temperature sensor 36 senses the temperature change, due to the different viscosities of the adhesive at different temperatures, the push rod motor 44 is started through the electrical box 6 to drive the block 41 to move through the connecting rod 42, thereby controlling the rate of discharging the adhesive from the discharge channel 22.

[0037] The above specific embodiment is only an optional embodiment of the present invention.
