Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a PCB drill bit steel shank grinding equipment. Background Technology

[0002] The rapid development of electronic product technology has led to miniaturization, thinning, and portability in mobile phones, tablets, and wearable electronic devices. This necessitates increasingly smaller and denser printed circuit boards (PCBs) and IC chips used in these products. The electronic components soldered onto PCBs and IC chips are also becoming smaller, with increasingly finer pins. Consequently, the number of pins per unit area on the PCB increases significantly, requiring even smaller and more precise hole diameters on the PCB. Drill bits are the tools used for drilling holes in PCBs. However, existing PCB drill bit grinding equipment with steel shanks generates debris that flies in all directions during grinding, interfering with the operator's work.

[0003] To address the aforementioned technical issues, Chinese Patent No. CN214979928U discloses a PCB drill bit steel shank grinding device, comprising a base plate, a support plate on one side of the top of the base plate, a first motor on the side wall of the support plate away from the slide groove, the output shaft of the first motor passing through the support plate, a grinding disc fixedly attached to one end of the output shaft of the first motor, a first arc-shaped plate fixedly attached to the side wall of the support plate outside the grinding disc, a second arc-shaped plate movably connected to the outer wall of the first arc-shaped plate, an arc-shaped stop on the side wall of the support plate outside the second arc-shaped plate, and an arc-shaped through hole on the side wall of the arc-shaped stop.

[0004] Although the existing technical solution described above can block the chips generated during grinding, after the processing is completed, the workers still need to manually clean the residue remaining on the first and second arc plates, which is time-consuming and labor-intensive. In addition, the tiny residue particles are easily stirred and fly during cleaning, which can be easily inhaled by nearby workers, thus affecting their health. Summary of the Invention

[0005] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a PCB drill bit steel shank grinding device. This device aims to solve the problem that, after processing, existing grinding equipment still requires manual cleaning of residual debris on the first and second curved plates, which is time-consuming and labor-intensive. Furthermore, the tiny debris particles are easily stirred up and airborne during cleaning, making them highly susceptible to inhalation by nearby workers, thus affecting their health.

The material suction and recovery mechanism includes a material suction component and a docking interception component. The material suction component is used to absorb residual waste chips, and the docking interception component is used to intercept and guide the chips.

[0006] When using the PCB drill bit steel shank grinding equipment of this solution, the water pump can be started to transport water from the water storage tank to the nozzle and spray it onto the surface of the filter screen for rinsing. The residual debris and impurities are washed down along the inclined section of the fixed frame. Some of the water that falls through the filter screen can be intercepted by the push plate and discharged together with the washed-down debris through the through hole. After a certain amount of debris is collected, the valve can be opened to allow the wastewater mixed with the debris to be discharged through the discharge pipe. The structure is simple and easy to operate, which makes it convenient for workers to collect and discharge the intercepted debris. At the same time, it avoids the inhalation of small debris particles by workers, ensuring the health of the workers.

[0017] This specific embodiment is a PCB drill bit steel shank grinding device, the structural schematic diagram of which is shown below. Figure 1-6 As shown, a PCB drill bit steel shank grinding device includes a base 1, a vertical plate installed at one top end of the base 1, a grinding machine body 2 installed on one side of the vertical plate, a baffle cylinder 3 installed on one side of the outer wall of the vertical plate around the grinding machine body 2, an extension hole opened in the center of the interior of a cover plate 4 installed on one side of the outer wall of the baffle cylinder 3, and a suction and recovery mechanism installed on one side of the baffle cylinder 3. The suction and recovery mechanism includes a suction component and a docking interception component. The suction component is used to absorb residual waste, and the docking interception component is used to intercept and guide the debris. When in use, the device can absorb residual waste through the suction component and intercept and guide the debris through the docking interception component. The structure is simple and easy to operate, making it convenient for workers to collect and discharge the intercepted debris in a centralized manner, while avoiding the inhalation of small debris particles by workers, thus ensuring the health of workers.

[0018] In this embodiment, the material suction assembly includes a flow channel at the bottom of the baffle cylinder 3, a discharge pipe 5 at the bottom of the baffle cylinder 3 corresponding to the flow channel, a recovery box 6 at the bottom of the discharge pipe 5, a suction pipe 7 embedded in one side of the outer wall of the recovery box 6, a suction pump 8 at the other end of the suction pipe 7, and a water storage tank 9 near the top of one side of the outer wall of the recovery box 6. The grinding machine body 2 can be started to process the material. The baffle cylinder 3 can intercept the debris to prevent splashing. The suction pump 8 can cooperate with the suction pipe 7 to perform suction operation, sucking the intercepted debris into the recovery box 6 through the flow channel and the discharge pipe 5. The filter screen 13 can prevent debris from entering the suction pump 8.

[0019] Secondly, in this embodiment, the docking interception assembly includes a fixing frame 12 installed on one side of the inner wall of the recycling bin 6. A filter screen 13 is embedded in the top of the fixing frame 12. A first pushing groove is opened on one side of the fixing frame 12, and a second pushing groove is opened on the outer wall of the recycling bin 6 near the fixing frame 12. A pushing plate 14 is slidably connected to the inner side of the first and second pushing grooves. A through hole is opened at one end of the pushing plate 14. A support plate 15 is installed on the outer wall of the recycling bin 6 on the side of the second pushing groove. A docking groove is opened on the protruding end of the support plate 15 and the opposite side of the outer wall of the recycling bin 6. An abutment groove is opened on both sides of the docking groove. An abutment plate 16 is slidably connected to the inner side of the abutment groove. Multiple sets of first springs 17 are arranged and installed between the outer wall of the abutment plate 16 and the inner wall of the abutment groove. Abutment grooves are installed on both sides of the outer wall of the protruding end of the pushing plate 14. The sliding connection of the docking plate 18 and the abutment plate 16 are provided with corresponding inclined surfaces at their opposite ends. One section of the support plate 15 is inclined. After the suction pump 8 is turned off after the suction is completed, some debris can slide down the inclined section of the fixing frame 12. Then, the push plate 14 is pushed towards the inside of the recycling box 6, so that the through hole moves to the outside of the fixing frame 12. Then, after the protruding end of the push plate 14 is attached to the outer wall of the recycling box 6, one set of docking plates 18 is inserted into the docking groove. The docking plate 18 abuts against the two sets of abutment plates 16. After the inclined surfaces contact, the abutment plates 16 are forced to squeeze the first spring 17 to retract. After the docking plate 18 is fully pushed into the docking groove, the first spring 17 can drive the abutment plates 16 to pop out and abut against the two ends of the docking plate 18 to lock and prevent the position of the push plate 14 from moving randomly.

[0020] In addition, in this embodiment, a water inlet cylinder is installed at one end of the top of the water storage tank 9, and a water pump 10 is installed at one end of the top of the recycling tank 6. The suction end of the water pump 10 extends to the inside of the water storage tank 9, and a nozzle 11 is installed at the outlet end of the water pump 10 extending to the inside of the recycling tank 6. A discharge pipe 22 is embedded in one side of the outer wall of the recycling tank 6, and a valve is installed at one end of the discharge pipe 22. At this time, the water pump 10 can be started to transport the water inside the water storage tank 9 to the nozzle 11 and spray it onto the surface of the filter screen 13 for rinsing. The residual debris and impurities are washed down along the inclined section of the fixing frame 12. Some of the water that falls through the filter screen 13 can be intercepted by the push plate 14 and discharged down together with the washed-down debris through the through hole. After a certain amount of debris is collected, the valve can be opened to allow the sewage mixed with the debris to be discharged through the discharge pipe 22.

[0021] Furthermore, in this embodiment, a groove is provided on one side of the outer wall of the recycling box 6 and the tray 15, located at the abutment groove. A pull rod 19 is installed on the outer wall of the abutment plate 16 between two sets of first springs 17. The pull rod 19 is slidably connected to the groove. A first fixing plate 20 is installed at one end of the pull rod 19 extending to the outside of the groove. A second fixing plate is rotatably connected to one side of the first fixing plate 20. A pressing plate 21 is rotatably connected to the other end between the two sets of second fixing plates. Then, the pressing plate 21 can be pushed to extend the two sets of second fixing plates. The first fixing plate 20 drives the pull rod 19 to move inside the groove, causing the abutment plate 16 to retract inside the abutment groove, thereby squeezing the first spring 17 to retract again. At this time, the docking plate 18 on that side can be pulled out, allowing the push plate 14 to move back to its original position. After resetting, the docking plate 18 on the other side will abut and lock with the abutment plate 16 on the other tray 15 again, preventing positional displacement from affecting the suction operation.

[0022] When using the PCB drill bit shank grinding equipment of this solution, the grinding machine body 2 can be started to process the material. The baffle cylinder 3 can intercept the debris to prevent splashing. The suction pump 8 can be started in conjunction with the suction pipe 7 to perform suction operation. The intercepted debris is sucked into the inside of the recovery box 6 through the flow channel and the discharge pipe 5. The filter screen 13 can prevent debris from entering the inside of the suction pump 8. After the suction is completed and the suction pump 8 is turned off, some debris can slide down the inclined section of the fixed frame 12, and then the push plate 1... 4. Push the pusher plate 14 towards the inside of the recycling bin 6, causing the through hole to move to the outside of the fixing frame 12. Then, after the protruding end of the pusher plate 14 is attached to the outer wall of the recycling bin 6, one set of docking plates 18 inserts into the docking groove. The docking plate 18 abuts against the two sets of abutting plates 16. After contact at the inclined surfaces, the abutting plates 16 are forced to compress the first spring 17 to retract. After the docking plate 18 is fully pushed into the docking groove, the first spring 17 can drive the abutting plates 16 to pop out and abut the two ends of the docking plate 18 to lock. To prevent the push plate 14 from moving arbitrarily, the water pump 10 can be started to deliver water from the water storage tank 9 to the nozzle 11 and spray it onto the surface of the filter screen 13 for rinsing. This washes away any remaining debris and impurities along the inclined section of the fixing frame 12. Some of the water that falls through the filter screen 13 can be intercepted by the push plate 14 and discharged through the through-hole along with the washed-down debris. After collecting a certain amount of debris, the valve can be opened to allow the wastewater mixed with the debris to be discharged through the discharge pipe 22. Then, the push plate 14 can be used to further clean the filter screen. Pressing the pressure plate 21 causes the two sets of second fixed plates to extend and move. The first fixed plate 20 drives the pull rod 19 to move inside the groove, causing the abutment plate 16 to retract inside the abutment groove, thereby squeezing the first spring 17 to retract again. At this time, the docking plate 18 on that side can be pulled out, allowing the push plate 14 to move back to its original position. After resetting, the docking plate 18 on the other side will abut and lock with the abutment plate 16 on the other side support plate 15 again to prevent positional displacement from affecting the suction operation.

[0023] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0024] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
