[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1 to 5 As shown, this utility model provides a lifting mechanism for a grinding needle machine platform, including a support frame 1. A cylinder 3 is fixedly connected to the bottom of the inner cavity of the support frame 1. A mounting platform 4 is fixedly connected to the output end of the cylinder 3. A support plate 5 is fixedly connected to the top of the mounting platform 4. A motor 6 is fixedly connected to the front side of the support plate 5. A conveying roller 7 is fixedly mounted on the output shaft of the motor 6. A drive gear 8 is fixedly connected to the rear side of the conveying roller 7. A cleaning brush rod 11 and an absorption roller 21 are fixedly connected to the left and right ends of the rear side of the mounting platform 4, respectively. A driven gear 2 10 is fixedly connected to the rear side of the cleaning brush rod 11. A driven gear 1 9 is fixedly connected to the rear side of the absorption roller 21. The driven gear 1 9 and the driven gear 2 10 mesh with two drive gears 8, respectively. A collection box 13 is fixedly connected to the left side of the mounting platform 4.
[0021] The motor 6 drives the conveyor roller 7 to rotate, which in turn drives the polishing belt 12 to rotate. The polishing belt 12 polishes the needle part of the probe card. Then, the conveyor roller 7 drives the drive gear 8 to rotate, which in turn drives the driven gear 10 to rotate, which in turn drives the cleaning brush rod 11 to rotate. The drive gear 8 also drives the driven gear 9 to rotate, which in turn drives the absorption roller 21 to rotate. The rotation of the cleaning brush rod 11 cleans the outer surface of the polishing belt 12, and the collection box 13 collects the debris and wastewater. Then, the absorption roller 21 wipes away any remaining water stains on the outer surface of the polishing belt 12. This achieves the cleaning of the outer surface of the polishing belt 12 by the cleaning brush rod 11 and the absorption roller 21, thus preventing the debris generated during polishing from remaining on the outer surface of the polishing belt 12 and affecting its continued use.
[0022] Among them, a conveying pipe 16 is fixedly connected to the front side of the mounting platform 4, a water pump 18 is fixedly connected to the bottom of the conveying pipe 16, a spray pipe 17 is fixedly connected to the top of the conveying pipe 16, and a telescopic pipe 19 is fixedly connected to the input end of the water pump 18.
[0023] By connecting an external water source to the telescopic pipe 19, the water pump 18 is started to draw water in along the telescopic pipe 19 and deliver it to the spray pipe 17 along the conveying pipe 16. The water is then sprayed onto the outer surface of the polishing belt 12 through the spray pipe 17, and the polishing belt 12 helps to reduce dust from the debris generated by the polishing of the probe card, thereby preventing the debris from flying and affecting the surrounding sanitary environment.
[0024] Among them, a collection box 13 is fixedly connected to the left side of the mounting platform 4. The collection box 13 is located below the cleaning brush rod 11, and a telescopic tube 14 is fixedly connected to the bottom end of the collection box 13.
[0025] The outer surface of the polishing belt 12 is cleaned by the cleaning brush rod 11, and the wastewater from the cleaning enters the collection box 13 and is then discharged through the telescopic tube 14 at the bottom of the collection box 13.
[0026] Among them, a fixing plate 15 is fixedly connected to the left side of the bottom end of the inner cavity of the support frame 1, a fixing plate 20 is fixedly connected to the middle of the bottom end of the inner cavity of the support frame 1, the fixing plate 15 is fixedly connected to the bottom of the telescopic tube 14, and the fixing plate 20 is fixedly connected to the bottom of the telescopic tube 19.
[0027] The telescopic pipe 14 is fixed by the fixing plate 15, and the telescopic pipe 29 is fixed by the fixing plate 20. When the cylinder 3 drives the mounting platform 4 to rise and fall, the telescopic pipe 14 and the telescopic pipe 29 can extend and retract, thereby fixing the bottom ends of the telescopic pipe 14 and the telescopic pipe 29, so that sewage can be discharged along the telescopic pipe 14 and water can enter from the telescopic pipe 2.
[0028] The cleaning brush rod 11 and the absorption roller 21 are both in contact with the outer surface of the polishing belt 12, and a disc is provided on the rear side of the conveying roller 7, with the front side of the disc in contact with the rear side of the polishing belt 12.
[0029] By having the cleaning brush rod 11 and the absorption roller 21 adhere to the outer surface of the polishing belt 12, the cleaning brush rod 11 can clean and wipe the outer surface of the polishing belt 12. Then, the absorption roller 21 wipes away the water stains remaining on the outer surface of the polishing belt 12, and the disc of the conveying roller 7 limits the polishing belt 12, thereby ensuring the stability of the polishing belt 12 during operation.
[0030] Among them, the spray pipe 17 is inclined towards the grinding belt 12, and the top of the support frame 1 is fixedly connected to the clamping plate 2.
[0031] The spray pipe 17 is tilted towards the grinding belt 12, so that the spray pipe 17 can spray water onto the outer surface of the grinding belt 12. Then, the clamping plate 2 at the top of the support frame 1 can limit and fix the probe card. Then, the cylinder 3 is started to drive the grinding belt 12 to rise and fall, and the distance between the grinding belt 12 and the probe card is adjusted, so that the probe card can be ground by the grinding belt 12.
[0032] The working principle and usage process of this utility model are as follows: Connect the external water source to the telescopic pipe 19, place the probe card face down in the middle of the clamping plate 2, then start the cylinder 3 to drive the mounting platform 4 to rise, and start the motor 6 to drive the conveyor roller 7 to rotate, thereby driving the grinding belt 12 to rotate, and the grinding belt 12 to grind the probe card.
[0033] Next, the water pump 18 is started to transport water along the telescopic pipe 19 and the conveying pipe 16 to the spray pipe 17, and spray it onto the surface of the grinding belt 12 through the spray pipe 17, thereby preventing the debris generated during grinding from flying.
[0034] When the conveyor roller 7 rotates, it drives the drive gear 8 to rotate. Through the meshing of the two drive gears 8, driven gear 19, and driven gear 20, driven gear 19 and driven gear 20 rotate, thereby driving the cleaning brush rod 11 and the absorption roller 21 to rotate. When the cleaning brush rod 11 rotates, it wipes the surface of the polishing belt 12 and sweeps the wastewater with debris to the collection box 13, and then discharges it through the telescopic tube 14 at the bottom of the collection box 13.
[0035] When the absorption roller 21 rotates, it wipes away the water stains remaining on the outer surface of the polishing belt 12.
