Furthermore, when the adhesive is placed in the adhesive box, it is easily exposed to air, making it difficult to guarantee the quality of the adhesive and affecting the coating effect.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a coating device for transistor processing, comprising a base with an open top, and further comprising an adsorption mechanism, a lifting mechanism and a support mechanism. The adsorption mechanism is connected to one side of the base through the lifting mechanism, the lifting mechanism is fixed to one side of the base, and the support mechanism is disposed inside the base.

[0020] like Figure 1-4 As shown, a coating device for transistor processing includes a base 1 with an open top, an adsorption mechanism 2, a lifting mechanism 3, and a bearing mechanism 4. The adsorption mechanism 2 is connected to one side of the base 1 via the lifting mechanism 3, the lifting mechanism 3 is fixed to one side of the base 1, and the bearing mechanism 4 is disposed inside the base 1.
[0021] The adsorption mechanism 2 includes an adsorption plate 5, adsorption holes 6, a connecting pipe 7, and an air pump 8. The air pump 8 is connected to the base 1 via a lifting mechanism 3. One end of the connecting pipe 7 is connected to the output end of the air pump 8. The adsorption plate 5 is connected to the base 1 via the lifting mechanism 3. The adsorption plate 5 is an internally inflated membrane mechanism. The other end of the adsorption plate 5 is connected to the connecting pipe 7. The adsorption holes 6 are opened on the adsorption plate 5 and are evenly spaced around the axis of the adsorption plate 5.
[0022] like Figure 1-2 As shown, in order to achieve the lifting and lowering of the adsorption plate, the lifting mechanism 3 includes a mounting plate 9, an electric telescopic rod 10, a connecting horizontal rod 11, and a connecting vertical rod 12. The mounting plate 9 is fixed to one side of the base 1, the electric telescopic rod 10 is fixed to the mounting plate 9, one end of the connecting horizontal rod 11 is fixed to the telescopic end of the electric telescopic rod 10, the connecting vertical rod 12 is fixed to the other end of the connecting horizontal rod 11, the air pump 8 is fixed to the top of the connecting vertical rod 12, and the adsorption plate 5 is fixed to the lower end of the connecting vertical rod 12.
[0023] like Figure 1-4 As shown, in order to reduce the contact of the colloid with air and facilitate dipping, the carrier mechanism 4 includes a carrier cavity 13 and a box cover 14. The box cover 14 is movably snapped into the top opening of the base 1. The box cover 14 and the internal opening of the base 1 form the carrier cavity 13. The box cover 14 is provided with a glue application hole 15, which corresponds to the position of the adsorption hole 6. A colloid bag 16 is placed in the center of the carrier cavity 13. A liquid discharge pipe 17 is connected to the colloid bag 16. A one-way valve 18 is provided on the liquid discharge pipe 17. A flexible glue scraper 19 is provided on the upper surface of the box cover 14. The flexible glue scraper 19 is arranged in an inverted L shape and is symmetrically arranged with the glue application hole 15 as the center.
[0024] In practical use, the transistor is placed in the adsorption hole 6. At this time, the air pump 8 can be used to inflate the adsorption plate 5 so that the adsorption hole 6 initially adapts to the size of the transistor. After placement, the adsorption plate 5 is further inflated so that the inner wall of the adsorption hole 6 is tightly attached to the outer wall of the transistor, so that it is stably adsorbed and fixed. The one-way valve 18 is opened so that the colloid in the colloid bag 16 flows into the carrier cavity 13. The electric telescopic rod 10 is started and lowered, bringing the adsorption plate 5 down and lowering the transistor. The transistor passes through the glue hole 15 and contacts the colloid for dipping. After dipping, the electric telescopic rod 10 is started in reverse so that the adsorption plate 5 drives the transistor up. During the rise of the transistor, it passes through the middle of the flexible glue scraper 19 and is squeezed to deform the flexible glue scraper 19. The flexible glue scraper 19 is made of silicone or rubber and scrapes off the excess colloid on the transistor, so that the excess colloid falls back into the carrier cavity 13.
