Description

Technical Field

[0001] This utility model relates to the field of silicon wafer processing technology, and in particular to a vacuum adhesive stabilization device. Background Technology

[0002] In modern industrial production, adhesives are widely used. In silicon wafer processing, the quality of the adhesive directly affects product performance and reliability. However, the presence of air bubbles in the adhesive leads to poor stability, becoming a key challenge restricting the improvement of product quality.

[0003] Currently, existing vacuum adhesive stabilizing tanks for silicon wafer processing use a single vacuum pump to remove air bubbles, resulting in slow removal speed and incomplete removal, leading to unstable adhesive dispensing during subsequent use. Therefore, to achieve faster and more complete air bubble removal, promote technological progress in the industry, and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from existing vacuum adhesive stabilizing devices. Utility Model Content

[0004] The purpose of this invention is to solve the problems of slow speed and incomplete discharge in existing vacuum adhesive stabilization devices.

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

[0006] A vacuum adhesive stabilizing device includes a storage tank, a sealing cover fixedly connected to the top of the storage tank, a feed valve connected to the top of the sealing cover via a flange, a vacuum pump fixedly connected to the outer wall of the top of the sealing cover, the air inlet of the vacuum pump being sealed and inserted into the sealing cover, a motor fixedly connected to the outer wall of the top of the sealing cover, a connecting rod keyed to the output end of the motor, and multiple stirring blades fixedly connected to the outer wall of the connecting rod.

[0007] Furthermore, a pressure gauge is sealed to the top of the sealing cap.

[0008] Furthermore, an air pump is fixedly connected to the top outer wall of the sealing cover, and the air outlet of the air pump is sealed and inserted into the sealing cover.

[0009] Furthermore, a one-way valve is connected to the top of the sealing cover via a flange, and a discharge pipe is sealed and inserted into the top of the one-way valve.

[0010] Furthermore, a feed pipe is sealed and inserted into the bottom end of the one-way valve.

[0011] Furthermore, two annular blocks are bonded to the outer circumference of the storage tank.

[0012] Furthermore, the annular block has multiple mounting grooves around its circumference, and a rubber sleeve is bonded inside the mounting groove. A vibrator is fixedly connected inside the rubber sleeve.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By using a vacuum pump to extract the gas from the storage tank, a vacuum is created in the storage tank. At the same time, the stirring blades rotate under the drive of the motor, which stirs the glue. This causes small air bubbles in the glue to collide with each other and form large air bubbles, which then rise quickly to the surface. This speeds up the vacuuming process and completely removes the air bubbles.

[0015] 2. By using an air pump to introduce nitrogen into the storage tank, the pressure inside the storage tank is increased. Under the action of pressure, the glue is squeezed into the feed pipe and then discharged from the discharge pipe for use, which is convenient and quick. Attached Figure Description

[0020] 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.

[0021] Reference Figures 1-3 A vacuum adhesive stabilizing device includes a storage tank 1, a sealing cover 2 fixed to the top of the storage tank 1 by bolts, a feed valve 4 connected to the top of the sealing cover 2 by a flange, a vacuum pump 5 fixed to the outer wall of the top of the sealing cover 2 by bolts, the air inlet of the vacuum pump 5 being sealed and inserted into the sealing cover 2, and the gas in the storage tank 1 being extracted under the action of the vacuum pump 5, thereby evacuating the storage tank 1.

[0022] A motor 10 is bolted to the top outer wall of the sealing cap 2. The motor 10 rotates at 100-150 revolutions per minute. A connecting rod 11 is keyed to the output end of the motor 10. Multiple stirring blades 12 are bolted to the outer wall of the connecting rod 11. The stirring blades 12 have an inclination angle of 5-15 degrees and are made of stainless steel with a smooth surface, thus avoiding the residue of glue on the stirring blades 12. Driven by the motor 10, the connecting rod 11 rotates, thereby driving the stirring blades 12 to rotate, which in turn stirs the glue, causing small air bubbles in the glue to collide with each other to form large air bubbles, so that the large air bubbles can quickly rise to the surface.

[0023] A pressure gauge 3 is inserted into the top of the sealing cap 2 to observe the pressure inside the storage tank 1.

[0024] An air pump 6 is bolted to the top outer wall of the sealing cover 2. The air pump 6 is a high-pressure air pump. The air outlet of the air pump 6 is sealed and inserted into the sealing cover 2. A one-way valve 7 is connected to the top of the sealing cover 2 through a flange. The air pressure of the air pump 6 can open the one-way valve 7. The top of the one-way valve 7 is sealed and inserted into the discharge pipe 9, and the bottom of the one-way valve 7 is sealed and inserted into the inlet pipe 8. Under the action of the air pump 6, nitrogen is introduced into the storage tank 1, thereby increasing the pressure inside the storage tank 1. Under the action of pressure, the glue is squeezed into the inlet pipe 8 and then discharged from the discharge pipe 9 for use.

[0025] Two annular blocks 13 are bonded to the outer circumference of the storage tank 1. Multiple mounting grooves 14 are provided around the circumference of the annular blocks 13. A rubber sleeve 15 is bonded inside the mounting groove 14. A vibrator 16 is fixed inside the rubber sleeve 15 by bolts. The vibrator 16 is a Kelisonic-3825 high-frequency piezoelectric ceramic ultrasonic vibrator. The vibrator 16 makes the air bubbles in the glue rise and be expelled more quickly.

[0026] The working principle of this embodiment is as follows: When in use, firstly, glue is put into storage tank 1 through feed valve 4. Then, motor 10 is started. Under the drive of motor 10, connecting rod 11 rotates, thereby driving stirring blade 12 to rotate, which in turn stirs the glue, so that small bubbles in the glue collide with each other to form large bubbles, so that the large bubbles rise quickly. At the same time, vacuum pump 5 is started. Under the action of vacuum pump 5, the gas in storage tank 1 is extracted, thereby creating a vacuum in storage tank 1.

[0027] Next, the air inlet of the air pump 6 is connected to the nitrogen storage tank. The air pump 6 is started, and nitrogen is introduced into the storage tank 1 by the air pump 6, thereby increasing the pressure in the storage tank 1. Under the action of pressure, the glue is squeezed into the feed pipe 8 and then discharged from the discharge pipe 9 for use. The vibrator 16 makes the air bubbles in the glue rise and be expelled more quickly. At the same time, the rubber sleeve 15 makes the distribution of the vibration generated by the vibrator 16 more uniform so that the air bubbles can be expelled better.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
