[0023] The present invention will be further described below with reference to the accompanying drawings:
[0024] like Figure 1-4 As shown, this embodiment provides a splash-proof cooling mechanism for bonding wire processing, including a mounting base 1 and a grinding mechanism 2. A splash-proof component 3 is provided on the front of the mounting base 1. The splash-proof component 3 includes an upper protective cover 301, a lower protective cover 302, a sliding protective cover 303, and two limiting hooks 304. The upper protective cover 301, lower protective cover 302, and sliding protective cover 303 are all made of transparent material to facilitate observation of the grinding process. Fixed protective strips 305 are fixedly installed on both sides of the top of the lower protective cover 302. The top of the fixed protective strips 305 has an arc-shaped groove. The bottom of the sliding protective cover 303... Both sides have limiting grooves 306. The top of the inner wall of the limiting groove 306 has an arc-shaped groove 2. The arc-shaped groove 1 and the arc-shaped groove 2 are spliced together to form a circle for the bonding wire to pass through. Both sides of the sliding protective cover 303 are fixedly provided with limiting handle rings 307. The ring on the limiting handle ring 307 is hooked by the limiting hook 304, which can limit the position of the sliding protective cover 303 and prevent the sliding protective cover 303 from sliding down. The inner surface of the lower protective cover 302 is fixedly connected with a traction plate 308. The traction plate 308 is used to introduce water flow into the opening area of the collection tank 9 for accurate collection.
[0025] The mounting base 1 has two sliding grooves 4 on its front side. The upper protective cover 301 is fixedly installed on the top of the inner wall of the mounting base 1, and the lower protective cover 302 is fixedly installed on the bottom of the inner wall of the mounting base 1, around the collection groove 9. The sliding protective cover 303 is slidably installed between the two sliding grooves 4. A support strip is fixedly connected to the bottom of the sliding protective cover 303. A support groove is opened on the top of the lower protective cover 302. The support strip and the support groove correspond to each other, which can seal the joint between the two to prevent water stains from seeping out from the gap between them. The upper protective cover 301... A through hole 5 is provided on the right side. A water pipe 6 is provided on the top of the mounting base 1. Several cooling nozzles 7 are fixedly provided on the outer surface of the water pipe 6. A flexible hose is provided on the top of the cooling nozzle 7. One end of the flexible hose is connected to the water storage chamber 11 and a solenoid valve is provided inside. A rotating handle 8 is fixedly connected to the right end of the water pipe 6. The rotating handle 8 makes it easy to change the orientation of the water pipe 6 and the cooling nozzles 7, so that the cooling nozzles 7 can wash away the debris on the sliding protective cover 303, the lower protective cover 302 and the upper protective cover 301, and prevent the debris from adhering to the protective cover due to water stains.
[0026] The rotating handle 8 is rotatably installed inside the through hole 5. When the rotating handle 8 is not rotated by external force, the water pipe 6 and the cooling nozzle 7 will remain hanging due to their own weight. The top of the mounting base 1 is provided with a collection tank 9, which is used to collect water containing debris sprayed from the cooling nozzle 7. The inside of the collection tank 9 is provided with a filter layer 10, which can be pulled out from the inside of the collection tank 9 for cleaning to prevent the top of the filter layer 10 from being blocked by debris, reducing the filtration efficiency and the rate of water flow. The inside of the mounting base 1 is provided with a water storage chamber 11, and the top of the water storage chamber 11 is provided with a water inlet. A sealing plug is provided in the water inlet to introduce water into the water storage chamber 11, and the sealing plug prevents water from flowing out. The back of the mounting base 1 is fixedly installed with a water pump 12 by a mounting bracket. The water pump 12 is connected to an external control switch through existing technology.
[0027] The water pump 12 is fixedly connected to the water inlet pipe 13, one end of which extends into the inside of the collection tank 9. The water pump 12 is fixedly connected to the water outlet pipe 14, which extracts the filtered water from the collection tank 9. One end of the water outlet pipe 14 extends into the inside of the water storage chamber 11, which sends the filtered water into the water storage chamber 11 for reuse. The grinding mechanism 2 includes several grinding heads 201, a motor 202, several gears 203, and a toothed ring 204. The motor 202 is connected to the motor through existing technology and an external control switch. Several grinding heads 201 are rotatably mounted on the front of the mounting base 1. Several gears 203 are fixedly connected to one end of several grinding heads 201 respectively. The back of the mounting base 1 has a mounting groove, and the gears 203 are in the mounting groove. One end of the output shaft of the motor 202 is fixed to one of the gears 203. Several gears 203 mesh with the tooth surfaces of the toothed ring 204.
[0028] During use: During the bonding wire grinding process, the sliding protective cover 303 is positioned between the upper protective cover 301 and the lower protective cover 302, forming a sealed space in the area being ground by the grinding head 201. The solenoid valve in the hose is activated, drawing water from the water storage chamber 11 into the water pipe 6 and the cooling nozzle 7. The cooling nozzle 7 sprays water onto the grinding position of the grinding head 201, cooling the bonding wire and the grinding head 201 as a whole. The washed-off bonding wire debris falls with the water, passing through the traction plate 308 into the collection tank 9, and then is filtered and reused through the filter layer 10. Once the water in the collection tank 9 accumulates to a certain level, the water pump 12 is activated to draw the filtered water into the inlet pipe 13, and then through the outlet pipe 14 into the water storage chamber 11 for reuse. Water and a small amount of debris splashed to the left by the high-speed rotation of the grinding head 201 will be intercepted by the sliding protective cover 303, preventing the grinding head 201 from carrying water stains and debris. The splashing of debris reduces the hygiene of the processing environment and avoids the need for manual cleaning by staff later. After grinding, the rotating handle 8 is manually rotated to change the angle of the water pipe 6 and the cooling nozzle 7. The cooling nozzle 7 sprays water onto the inner walls of the sliding protective cover 303, the lower protective cover 302, and the upper protective cover 301 to wash away the splashed debris. After releasing the rotating handle 8, the water pipe 6 and the cooling nozzle 7 will return to their original vertical downward position. Then, two people lift the sliding protective cover 303 upward, exposing the grinding head 201 and the bonding wire. The limiting hook 304 is hung on the limiting handle ring 307 to limit the position of the sliding protective cover 303. The manual operation process before and after the next bonding wire processing can be carried out. After the operation, the limiting hook 304 is removed from the limiting handle ring 307, and the sliding protective cover 303 can be slid downward to close the processing space between the grinding head 201 and the bonding wire.
