Description

Technical Field

[0001] This utility model relates to the technical field of mixing tank cleaning devices, and in particular to a mixing tank cleaning device for mixing semiconductor packaging materials. Background Technology

[0002] In the production of semiconductor packaging materials (such as epoxy molding compound and conductive silver paste), the mixing tank is the core equipment for achieving uniform mixing of various raw materials. Since the packaging materials are mostly high-viscosity fluids (viscosity 5000-20000 cP) and contain fillers (such as silicon micro powder and silver particles), a large amount of material will remain on the inner wall, bottom of the tank and surface of the stirring paddle after the mixing tank is used. If the residual material is not thoroughly cleaned, it will mix with the next batch of materials, resulting in composition deviation. Therefore, a cleaning device is needed to clean it.

[0003] However, existing technologies have some problems: traditional mixing tanks rely on manual cleaning with hand-held brushes dipped in solvents, requiring back-brushing of the inner wall, and the corners and dead corners of the tank are difficult to clean. Cleaning a single tank is time-consuming and labor-intensive, and the mixing tank is prone to shaking during the cleaning process due to brush friction or liquid impact, affecting its safety. Therefore, it is necessary to provide a mixing tank cleaning device for mixing semiconductor packaging materials to solve the above technical problems. Utility Model Content

[0004] This utility model provides a cleaning device for a mixing tank used for mixing semiconductor packaging materials. It solves the technical problems of traditional mixing tanks that rely on manual cleaning with a hand-held brush dipped in solvent, require back-brushing of the inner wall, and are difficult to clean in corners and dead corners. Cleaning a single tank is time-consuming and labor-intensive, and the mixing tank is prone to shaking due to brush friction or liquid impact during the cleaning process, which affects its safety.

[0005] To solve the above-mentioned technical problems, this utility model provides a stirring tank cleaning device for mixing semiconductor packaging materials, comprising:

[0006] A concave base, the interior of which is provided with a barrel, a support frame is fixedly connected to the rear side of the upper end of the concave base, a waterproof motor is provided below the support frame, and a brush disc is fixedly connected to the output end of the waterproof motor. The bristles of the brush disc are made of solvent-resistant nylon.

[0007] The device includes a fixing component and a lifting component. The fixing component is located on both sides of the concave base and is used to clamp and fix the barrel. The lifting component is located on the support frame and is used to drive the waterproof motor and the brush disc to lift.

[0008] Preferably, the fixing component includes an L-shaped support plate, an electric push rod is fixedly connected to the upper end of one side of the L-shaped support plate, and the output end of the electric push rod passes through the L-shaped support plate and is fixedly connected to an arc-shaped retaining ring.

[0009] Preferably, the lifting assembly includes a cylinder, the output end of which is fixedly connected to a push rod, the lower end of which extends through to the lower end of the support frame and is fixedly connected to the upper end of the waterproof motor.

[0010] Preferably, the inside of the arc-shaped retaining ring is fixedly connected to an anti-slip pad, and one side of the anti-slip pad is provided with anti-slip texture.

[0011] Preferably, the four corners of the lower end of the concave base are fixedly connected to columns, and the lower ends of the columns are fixedly connected to rubber pads.

[0012] Preferably, a limiting ring is slidably connected to the surface of the top rod, and the upper end of the limiting ring is fixedly connected to the upper end of the support frame. Three to four side spray holes are evenly distributed on the outer periphery of the brush disk. A liquid inlet pipe is connected to one side of the housing of the waterproof motor, and the liquid inlet pipe is connected to the side spray holes through the hollow channel inside the top rod for spraying cleaning liquid onto the inner wall of the barrel.

[0013] Compared with related technologies, the mixing tank cleaning device for semiconductor packaging materials provided by this utility model has the following advantages:

[0014] This utility model provides a cleaning device for a mixing tank of semiconductor packaging materials. The fixing component uses an electric push rod to drive an arc-shaped retaining ring to clamp the tank from both sides. With the limiting effect of the concave base, the amount of tank shaking can be controlled to <0.5mm, ensuring that the brush plate is in uniform contact with the tank wall, improving the cleaning consistency by 90%, and eliminating the risk of tank tipping over.

[0015] This invention provides a cleaning device for mixing semiconductor packaging materials in a stirring tank. A lifting assembly drives a brush disc (solvent-resistant nylon bristles) to move up and down, combined with a waterproof motor-driven rotary scrubbing motion (150-300 rpm), and the addition of cleaning fluid spray from side nozzles (flow rate 0.5-1.5 L / min). This thoroughly removes residue from corners and roots, reducing the residue rate from 15% to <0.5%. No disassembly of the stirring paddle is required, and the cleaning time for a single tank is reduced from 40 minutes to 8-10 minutes, increasing efficiency by over 75%.

[0016] This invention provides a mixing tank cleaning device for semiconductor packaging materials. The cleaning liquid is sprayed directionally through side spray holes, saving 60% of solvent compared to manual splashing (solvent consumption per tank <2L). The lifting and fixing actions are controlled by buttons, and can be operated by a single person, reducing labor intensity and meeting the automated production needs of semiconductor workshops.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1:

[0023] Please see Figure 1-3 This utility model provides a technical solution: a mixing tank cleaning device for semiconductor packaging materials, comprising: a concave base 1, a tank body 2 disposed inside the concave base 1, a support frame 3 fixedly connected to the rear side of the upper end of the concave base 1, a waterproof motor 4 disposed below the support frame 3, a brush plate 5 fixedly connected to the output end of the waterproof motor 4, the bristles of the brush plate 5 being made of solvent-resistant nylon, a fixing component 6 and a lifting component 7, the fixing component 6 being located on both sides of the concave base 1 and used to clamp and fix the tank body 2, and the lifting component 7 being located on the support frame 3 and used to drive the lifting of the waterproof motor 4 and the brush plate 5.

[0024] In this embodiment, the tub 2 to be cleaned is placed into the concave base 1. Then, the electric push rod 62 of the fixing component 6 is activated, and the output end extends to push the arc-shaped retaining ring 63 closer to the tub 2 until the inner anti-slip pad is in close contact with the outer wall of the tub 2. The symmetrical clamping force on both sides ensures that the axis of the tub 2 is collinear with the axis of the brush plate 5. Then, the cylinder 71 of the lifting component 7 is activated, and the output end of the cylinder 71 extends to drive the top rod 72 to move vertically downward along the limiting ring 10. The waterproof motor 4 and the brush plate 5 move downward accordingly until the brush plate 5 enters the interior of the tub 2. The limiting ring 10 restricts the radial sway of the top rod 72 to ensure that the brush plate 5 is concentric with the tub 2 and avoids collision with the tub wall.

[0025] Example 2:

[0026] Please see Figure 1-3As shown, based on Embodiment 1, this utility model provides a technical solution: the fixing component 6 includes an L-shaped support plate 61, an electric push rod 62 is fixedly connected to the upper end of one side of the L-shaped support plate 61, the output end of the electric push rod 62 passes through the L-shaped support plate 61 and is fixedly connected to an arc-shaped retaining ring 63; the lifting component 7 includes a cylinder 71, a push rod 72 is fixedly connected to the output end of the cylinder 71, the lower end of the push rod 72 passes through to the lower end of the support frame 3 and is fixedly connected to the upper end of the waterproof motor 4; the arc-shaped retaining ring 63 is internally fixedly connected to... The base is equipped with an anti-slip pad, and one side of the anti-slip pad has anti-slip texture. The four corners of the lower end of the concave base 1 are fixedly connected to the column 8, and the lower end of the column 8 is fixedly connected to the rubber pad 9. The surface of the top rod 72 is slidably connected to the limit ring 10, and the upper end of the limit ring 10 is fixedly connected to the upper end of the support frame 3. The outer periphery of the brush plate 5 is evenly distributed with 3-4 side spray holes. The housing of the waterproof motor 4 is connected to a liquid inlet pipe on one side, and the liquid inlet pipe is connected to the side spray holes through the hollow channel inside the top rod 72 for spraying cleaning liquid onto the inner wall of the barrel 2.

[0027] In this embodiment: the waterproof motor 4 is started, and the output shaft drives the brush disc 5 to rotate. The bristles contact the inner wall and bottom surface of the barrel 2 to scrub away residual materials. At the same time, the cleaning liquid is delivered to the side spray hole through the liquid inlet pipe and the hollow channel of the top rod 72 and sprayed onto the barrel wall to dissolve and wash away the residual particles scrubbed off, forming a synergistic cleaning effect of "mechanical scrubbing and chemical dissolution". The lifting component 7 drives the brush disc 5 to move up and down slowly to cover the full height of the barrel 2. After cleaning is completed, the cylinder 71 retracts and drives the brush disc 5 to rise to the outside of the barrel 2. The electric push rod 62 retracts and releases the barrel 2, and the cleaned barrel 2 can be taken out. The whole process is completed automatically without manual intervention.

[0028] The working principle of the mixing tank cleaning device for semiconductor packaging materials provided by this utility model is as follows:

[0029] Implementation steps for the first innovation point:

[0030] Step 1: Place the bucket 2 to be cleaned into the concave base 1, and then start the electric push rod 62 of the fixing component 6. The output end extends and pushes the arc-shaped retaining ring 63 closer to the bucket 2 until the anti-slip pad on the inner side is in close contact with the outer wall of the bucket 2. The symmetrical clamping force on both sides ensures that the axis of the bucket 2 is collinear with the axis of the brush plate 5.

[0031] Step 2: Activate cylinder 71 of lifting assembly 7 again. The output end of cylinder 71 extends and drives top rod 72 to move vertically downward along limit ring 10. Waterproof motor 4 and brush disc 5 move downward along with it until brush disc 5 enters the barrel 2. Limit ring 10 restricts the radial sway of top rod 72 to ensure that brush disc 5 is concentric with barrel 2 and avoids collision with barrel wall.

[0032] Implementation steps for the second innovation point:

[0033] Step 1: Start the waterproof motor 4. The output shaft drives the brush disc 5 to rotate. The bristles contact the inner wall and bottom surface of the barrel 2 to scrub away residual materials. At the same time, the cleaning liquid is delivered to the side spray hole through the liquid inlet pipe and the hollow channel of the top rod 72 and sprayed onto the barrel wall to dissolve and wash away the residual particles scrubbed off, forming a synergistic cleaning effect of "mechanical scrubbing and chemical dissolution". The lifting component 7 drives the brush disc 5 to move up and down slowly to cover the full height of the barrel 2.

[0034] Step 2: After cleaning, the cylinder 71 retracts, causing the brush plate 5 to rise to the outside of the barrel 2. The electric push rod 62 retracts and releases the barrel 2, allowing the cleaned barrel 2 to be removed. The entire process is automatic and requires no manual intervention.
