[0002] Currently, during the silicon wafer processing, a glue-applying device is used to coat the surface of the silicon wafer for subsequent processing.

[0003] However, existing adhesive dispensing devices often result in uneven adhesive distribution during use, leading to poor coating effects on silicon wafers. Therefore, in order to better realize the adhesive dispensing function for silicon wafers, promote technological progress in the industry, and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from the structure and application method of adhesive dispensing devices in the prior art. Utility Model Content

[0004] The purpose of this invention is to solve the problem of uneven glue discharge from existing glue dispensing devices, which leads to poor glue coating effect on silicon wafers, and to propose a new glue dispensing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The feeding component includes a stator cylinder inserted into the top of the mounting plate. A connector is fixedly connected to one side of the stator cylinder, and a top seat is fixedly connected to the top of the stator cylinder. A motor is fixedly connected to the top of the top seat, and a rotor cone is fixedly connected to the output end of the motor. The rotor cone is located inside the stator cylinder. The bottom of the dispensing head has a discharge port, and a material leveling component is provided inside the dispensing head. The material leveling component includes an arc plate, which is fixed between the inner walls of both sides of the dispensing head by bolts. A gap is left between the arc plate and the inner walls of both sides of the dispensing head. Multiple discharge pipes are sealed and inserted into the top of the dispensing head.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A novel adhesive dispensing device includes two sets of feeding components 2, a material conveying component 3 and a material outlet head 4, with a mounting plate 1 provided between the feeding components 2 and the material conveying component 3;

[0024] The feeding assembly 2 includes a stator cylinder 201, which is inserted into the top of the mounting plate 1. A connector 202 is integrally formed on one side of the stator cylinder 201. A top seat 203 is fixed to the top of the stator cylinder 201 by bolts. A motor 204 is fixed to the top of the top seat 203 by bolts. The speed of the motor 204 is 500–3000 rpm. A rotor cone 205 is fixed to the output end of the motor 204 by bolts. The cone angle of the rotor cone 205 is 5–10 degrees. The rotor cone 205 is located inside the stator cylinder 201. Under the drive of the motor 204, the rotor cone 205 rotates at high speed, thereby generating shear force and centrifugal force. Under the push of shear force and centrifugal force, the colloid flows downward.

[0025] The bottom of the discharge head 4 is provided with a discharge port 5, and the discharge head 4 is provided with a material leveling component 6. The material leveling component 6 includes an arc plate 602. The arc plate 602 is fixed between the inner walls of the two sides of the discharge head 4 by bolts. There is a gap of 1-2mm between the arc plate 602 and the inner walls of the two sides of the discharge head 4.

[0026] Multiple discharge pipes 601 are sealed and inserted into the top of the discharge head 4. The number of discharge pipes 601 can be 3-6. In this solution, there are 3 discharge pipes 601 evenly distributed. The bottom end of the discharge pipe 601 is located above the arc plate 602. The top end of the discharge pipe 601 is inserted into the material passage component 3. The colloid flows evenly from the multiple discharge pipes 601 to the arc plate 602. Then, the colloid overflows from both sides of the arc plate 602 and flows into the discharge head 4 through the gap between the arc plate 602 and the discharge head 4, which facilitates the dispersion and flow of the colloid so that the colloid is evenly coated on the silicon wafer.

[0027] The feeding assembly 3 includes a material collection box 301, which is fixed to the bottom of the mounting plate 1 by bolts. The bottom end of the stator cylinder 201 is inserted into the top of the material collection box 301. The bottom of the material collection box 301 is sealed with a discharge pipe 302, and the bottom end of the discharge pipe 302 is sealed with a connecting pipe 303. The bottom end of the connecting pipe 303 is fitted with a connecting box 304. The top end of the discharge pipe 601 is inserted into the bottom of the connecting box 304. The material collection box 301, the discharge pipe 302, the connecting pipe 303, and the connecting box 304 together form a smooth colloid conveying path, ensuring that the colloid enters the discharge head 4 smoothly.

[0028] The bottom outer wall of the connecting box 304 is fixed with a connecting seat 7 by bolts. The discharge head 4 is fixed to the bottom of the connecting seat 7 by bolts, which facilitates the discharge head 4. The material collection box 301 and the connecting box 304 are fixed with a fixing seat 8 by bolts. The top of the mounting plate 1 is welded with a connecting frame 9. One side of the top seat 203 is fixedly connected to one side of the connecting frame 9. One side of the connecting frame 9 is fixed with a mounting seat 10 by bolts. The mounting plate 1, connecting frame 9, fixing seat 8 and connecting seat 7 and other components ensure the stable installation and structural integrity of the entire device.

[0029] The working principle of this embodiment is as follows: In use, the colloid delivery pipe is connected to the connector 202, and the colloid is input into the stator cylinder 201 from the connector 202. Then, the motor 204 is started, and the rotor cone 205 rotates under the drive of the motor 204, thereby generating shear force and centrifugal force. Under the push of shear force and centrifugal force, the colloid flows downward and enters the connector box 304 through the stator cylinder 201, the material box 301, the discharge pipe 302, and the connector pipe 303. Then, the colloid flows evenly from multiple discharge pipes 601 to the arc plate 602. Then, the colloid overflows from both sides of the arc plate 602 and flows from the gap between the arc plate 602 and the discharge head 4 into the discharge head 4. Then, it is discharged from the discharge port 5, thereby uniformly coating the colloid onto the silicon wafer.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
