Description

Technical Field

[0001] This utility model relates to the field of chip processing, and in particular to a surface treatment device for integrated circuit chips. Background Technology

[0002] Integrated chips refer to transistors that are first integrated into chips with specific functions, and then integrated into chips using semiconductor technology according to application requirements. During chip processing, the surface of the chip needs to be cleaned. For example, patent document CN222568546U discloses a surface treatment device for electronic chip processing. When the mask is lowered by an electric push rod, the brush is attached to the chip surface. Then, the motor is started to drive the one-way threaded rod to rotate, so that the fixed frame moves along the surface of the support frame with the cooperation of the sliding rod. The brush cleans the chip surface. During the cleaning process, the exhaust fan is started and the dust generated during the cleaning process is collected by the mask through the collection pipe and sent into the collection box.

[0003] However, after a period of use, the brush will accumulate a lot of dust, which will affect the subsequent cleaning effect. Therefore, it is better to clean the dust on the brush in time. Usually, the brush needs to be disassembled, which increases the cumbersomeness of use, not only increasing the manual operation steps, but also affecting the cleaning efficiency of the chip. Utility Model Content

[0004] The purpose of this invention is to provide an integrated circuit chip surface treatment device in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An integrated circuit chip surface treatment device includes a main frame with two side plates. A conveyor belt is installed between the side plates. A mounting frame is slidably connected to the top of the side plates. A hydraulic cylinder is fixed on the mounting frame. A cover is fixed to the output shaft of the hydraulic cylinder. Guide plates are slidably connected to both sides of the cover. A cleaning mechanism is provided inside the cover. The cleaning mechanism includes a U-shaped frame with a cleaning brush fixed inside. Rotary shafts are fixed to both sides of the U-shaped frame and are rotatably connected to the cover. A gear is fixed on the rotating shaft, and a rack meshes with the rear side of the gear. The rack is fixed to the front side of the guide plate. A drive motor is fixed to one side of the cover. A toggle shaft is fixed to the output shaft of the drive motor and is rotatably connected inside the cover. An elastic mechanism is provided on the guide plate. An air extraction mechanism is provided on the mounting frame. A push-pull mechanism is provided on one side of the side plate. A clamping mechanism is provided behind the mounting frame.

[0007] Preferably, the elastic mechanism includes a top plate, which is fixedly connected to the top of the guide plate. A sleeve is fixedly fixed to the bottom of the top plate. A movable column is slidably connected inside the bottom end of the sleeve. The movable column is fixedly connected to the top of the cover. A spring is fixed between the top of the movable column and the inner wall of the sleeve. The spring is always in a compressed state.

[0008] Preferably, guide blocks are fixed on both sides of the cover, and guide grooves are provided on the guide plates, with the guide blocks slidably connected in the guide grooves.

[0009] Preferably, the air extraction mechanism includes a collection box, which is fixedly connected to the top of the mounting frame. An air extraction pump is fixedly mounted on the collection box, and a hose is fixedly connected to the collection box. An air extraction hood is fixedly connected to the air inlet end of the hose and is fixedly connected to the top of the housing.

[0010] Preferably, the push-pull mechanism includes a support plate, which is fixedly connected to one side of the side plate. A cylinder is fixedly connected to the top of the support plate, and a push-pull block is fixedly connected to the output end of the cylinder. The push-pull block is slidably connected to the side plate and fixedly connected to the mounting bracket.

[0011] Preferably, the clamping mechanism includes two supports, which are fixedly connected to the top of the side plate. A bidirectional lead screw is rotatably connected between the two supports, and a guide rod is fixedly connected between them.

A clamping bar is fixedly connected to the front side of the slider, and a clamping motor is fixedly connected to one side of the side plate. The output end of the clamping motor is fixedly connected to the bidirectional lead screw.

[0012] The beneficial effects are as follows: when it is necessary to clean the dust on the sweeping brush, the cover and guide plate are moved up. When the guide plate can no longer move up, the cover begins to move up relative to the guide plate, causing the gear to roll on the rack. The gear drives the sweeping brush to rotate so that the bristles face upward. Then, the drive motor drives the actuating shaft to rotate, knocking off the dust on the sweeping brush bristles. The dust is then sucked away by the air extraction mechanism. This reduces the frequency of disassembly and assembly of the sweeping brush, making it more convenient to use.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-6 As shown, an integrated circuit chip surface treatment device includes a main frame 1, which includes two side plates 101. A conveyor belt 102 is installed between the side plates 101. A mounting bracket 103 is slidably connected to the top of the side plates 101. A hydraulic cylinder 2 is fixed to the mounting bracket 103 by bolts. A cover 3 is fixed to the output shaft of the hydraulic cylinder 2. Guide plates 4 are slidably connected to both sides of the cover 3, allowing the cover 3 to slide up and down relative to the guide plates 4. A cleaning mechanism 5 is provided inside the cover 3. The cleaning mechanism 5 includes a U-shaped frame 501. A cleaning brush 502 is fixed inside the U-shaped frame 501 by screws. When the cleaning brush 502 needs to be replaced, the screws can be unscrewed. A rotating shaft 503 is welded to both sides of the U-shaped frame 501. The rotating shaft 503 is connected to the cover 3 by bearings. A gear 504 is fixed on the rotating shaft 503, and a rack 505 meshes with the rear side of the gear 504. The rack 505 is fixed to the front side of the guide plate 4. When the gear 504 rolls on the rack 505, the gear 504 drives the U-shaped frame 501 to rotate through the rotating shaft 503, thereby causing the cleaning brush 502 to flip. The drive motor 302 is fixed to one side of the cover 3 by bolts. The output shaft of the drive motor 302 is fixed to the actuating shaft 303. The actuating shaft 303 is connected to the inside of the cover 3 through the bearing. When the bristles of the cleaning brush 502 rotate to the top, the drive motor 302 drives the actuating shaft 303 to rotate. The actuating shaft 303 actuates the bristles, thereby loosening or falling off the dust, which makes it easier to remove the dust and clean the cleaning brush 502. The guide plate 4 is provided with an elastic mechanism 6, the mounting frame 103 is provided with an air extraction mechanism 7, the side plate 101 is provided with a push-pull mechanism 8, and the mounting frame 103 is provided with a clamping mechanism 9.

[0026] Guide blocks 301 are fixed on both sides of the cover 3. A guide groove 401 is provided on the guide plate 4. The guide blocks 301 are slidably connected in the guide groove 401. The elastic mechanism 6 includes a top plate 601, which is connected to the top of the guide plate 4 by screws. A sleeve 602 is fixed to the bottom of the top plate 601 by screws. A movable column 603 is slidably connected inside the bottom end of the sleeve 602. The movable column 603 is fixedly connected to the top of the cover 3. A spring 604 is fixed between the top of the movable column 603 and the inner wall of the sleeve 602. The spring 604 is always in a compressed state. In the natural state, the guide blocks 301... The cover 3 and the guide plate 4 are held at the bottom of the guide groove 401, keeping them relatively stationary. When the cover 3 is raised or lowered, the guide plate 4 will also be raised or lowered synchronously. However, when the top plate 601 moves upward and abuts against the mounting bracket 103, the guide plate 4 cannot move upward. If the cover 3 continues to move upward, the movable column 603 will retract into the sleeve 602, the spring 604 will be further compressed, and the gear 504 will also move upward relative to the rack 505. The gear 504 rotates, thereby driving the cleaning brush 502 to rotate, so that the bristles of the cleaning brush 502 rotate from the bottom to the top, which makes it easier to clean the bristles.

[0027] The air extraction mechanism 7 includes a collection box 701, which is connected to the top of the mounting bracket 103 by screws. An air pump 702 is connected to the collection box 701 by screws. A hose 703 is fixedly connected to the collection box 701. An air extraction hood 704 is fixedly connected to the air inlet end of the hose 703. The air extraction hood 704 is fixedly connected to the top of the cover 3. When the air pump 702 is started, a negative pressure is formed inside the cover 3, which can remove dust when cleaning the chip. In addition, dust is also removed when cleaning the bristles of the cleaning brush 502.

[0028] The push-pull mechanism 8 includes a support plate 801, which is welded to one side of the side plate 101. A cylinder 802 is bolted to the top of the support plate 801. A push-pull block 803 is fixedly connected to the output end of the cylinder 802. The push-pull block 803 is slidably connected to the side plate 101 and is fixedly connected to the mounting bracket 103.

[0029] The clamping mechanism 9 includes two supports 901, which are fixedly connected to the top of the side plate 101. A bidirectional lead screw 902 is connected between the two supports 901 via a bearing, and a guide rod 903 is fixedly connected thereto. A slider 904 is threaded onto the bidirectional lead screw 902, and the slider 904 is slidably connected to the guide rod 903. A clamping bar 905 is fixedly connected to the front side of the slider 904. A clamping motor 906 is bolted to one side of the side plate 101, and the output end of the clamping motor 906 is fixedly connected to the bidirectional lead screw 902.

[0030] Working principle: In use, the integrated circuit chip is placed on the conveyor belt 102, which transports the chip backward. When the chip moves below the cover 3, it stops moving. The clamping motor 906 drives the bidirectional lead screw 902 to rotate, which in turn drives the two sliders 904 to move closer. The sliders 904 drive the clamping bar 905 to move closer, thus clamping the chip. Then, the hydraulic cylinder 2 drives the cover 3 to move down, and the guide plate 4 moves down synchronously with the cover 3. The bristles at the bottom of the cleaning brush 502 contact the chip. The cylinder 802 drives the push-pull block 803 to move back and forth, which in turn drives the mounting bracket 103 to move back and forth, thus causing the cleaning brush 502 to move back and forth to clean the chip. The air pump 702... A negative pressure is created inside the cover 3 by evacuation, drawing dust into the collection box 701. When the sweeping brush 502 needs to be cleaned, the hydraulic cylinder 2 drives the cover 3 to move upward, and the guide plate 4 moves upward with the cover 3. When the top plate 601 presses against the mounting bracket 103, the guide plate 4 stops moving upward, and the cover 3 continues to move upward, thereby causing the gear 504 to move upward relative to the rack 505. The gear 504 drives the U-shaped frame 501 to rotate through the rotating shaft 503, causing the bristles of the sweeping brush 502 to rotate from the bottom to the top. The drive motor 302 drives the actuating shaft 303 to rotate, and the actuating shaft 303 actuates the bristles to loosen or fall off the dust, which is then directly drawn into the collection box 701, thus cleaning the sweeping brush 502.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
