Description

Technical Field

[0001] The present invention relates to the technical field of control motherboard grinding, and particularly to an edge protection type grinding device for control motherboard production. Background Art

[0002] In modern electronic manufacturing, the control motherboard is one of the core components, responsible for coordinating and managing various operations inside the device. Every link in the production process of the control motherboard is directly related to the performance and quality of the product. Edge treatment is one of the key steps in control motherboard manufacturing, aiming to eliminate burrs, irregular shapes, and other surface defects generated by cutting or stamping processes.

[0003] During the process of grinding the edge of the control motherboard, a large amount of metal or plastic debris will be generated due to the high-speed friction between the grinding tool and the control motherboard. These debris are ejected outward from the grinding area at a very high speed and are likely to scatter on the surface of the control motherboard. Coolant is used to cool the control motherboard during the grinding process, and the coolant will also splash onto the surface of the control motherboard along with the debris during the high-pressure spraying process.

[0004] The control motherboard has a high-precision circuit design and a complex component layout. Any tiny debris may be embedded in the gaps of the control motherboard, resulting in problems such as short circuits or signal interference. The coolant remaining on the surface of the control motherboard may absorb moisture, leading to electrochemical corrosion and causing irreversible damage. To ensure the quality of the control motherboard, in the subsequent production stage, the debris and coolant on the control motherboard are generally removed by methods such as ultrasonic cleaning, high-pressure air gun blowing, or chemical solvent wiping. These cleaning methods not only consume a large amount of time and human resources but also may cause additional resource waste, such as water resources, cleaning agents, etc. Summary of the Invention

[0032] Refer to Figures 1-9, An edge protection type grinding device for controlling the production of main boards, including a frame 1, a bracket 2, a sliding plate 3, a double-shaft motor 4, a driving lead screw 5, an installation box 6, a horizontal guide rod 7, a slider 8, a lead screw motor 1 9, an installation frame 10, a driving motor 11, a grinding wheel 12, an installation plate 13, a rubber ring 14, a feeding mechanism, a cooling mechanism and a chamfering mechanism. The top of the frame 1 is bolted with a bracket 2.

On the left and right sides of the top of the bracket 2, double-shaft motors 4 are bolted. The output shafts of the double-shaft motors 4 are connected with driving lead screws 5 through couplings. The driving lead screws 5 are rotatably connected to the top of the bracket 2, and the driving lead screws 5 are threadedly connected to the sliding plates 3. The thread directions of the two driving lead screws 5 on the same double-shaft motor 4 are opposite, so the two sliding plates 3 can be driven to move in opposite directions. The bottoms of the sliding plates 3 are bolted with installation boxes 6. On the front and rear sides of the inner top of the installation box 6, horizontal guide rods 7 are connected. The two horizontal guide rods 7 in the same installation box 6 are jointly slidably connected with a slider 8. Lead screw motors 1 9 are installed on the inner top of the installation box 6. The lead screws of the lead screw motors 1 9 are threadedly connected to the slider 8. The bottoms of the sliders 8 are bolted with installation frames 10. Driving motors 11 are bolted to the bottoms of the sliders 8. The driving motors 11 are located inside the installation frames 10, and the output shafts of the driving motors 11 are rotatably connected to the bottoms of the installation frames 10. The output shafts of the driving motors 11 are connected with grinding wheels 12. The grinding wheels 12 are located below the installation frames 10. On the mutually approaching sides of the front and rear installation boxes 6, installation plates 13 are bolted. Rubber rings 14 are connected to the lower parts of the installation plates 13. The installation plates 13 are detachable, and appropriate rubber rings 14 can be replaced according to the thickness of the control main board. The feeding mechanism is used to convey the control main board between the front and rear installation boxes 6. The control main board passes through the rubber ring 14 and extends into the installation box 6 and contacts the grinding wheel 12. The grinding wheel 12 grinds the control main board. The cooling mechanism is used to cool the grinding wheel 12 and the control main board. The chamfering mechanism is used to chamfer the control main board.

[0033] Refer to Figures 5-7, the feeding mechanism includes a rotating plate 151, a reduction motor 152, a support plate 153, a conveyor 154, a vertical guide rod 155, a lifting plate 156, a lead screw motor two 157, a lifting plate 158, an electric push rod 159, a pressing plate 1510, a pressing block 1511 and a telescopic rod 1512. The right side of the top of the frame 1 is rotatably connected to a rotating plate 151. The right side of the inner top of the frame 1 is bolted with a reduction motor 152. The output shaft of the reduction motor 152 is connected to the middle of the rotating plate 151. Both the top of the frame 1 and the top of the rotating plate 151 are bolted with a set of support plates 153. Each set has two support plates 153. The two support plates 153 in the same group are symmetrically arranged front and back. The upper parts of the two support plates 153 in the same group are jointly installed with a conveyor 154. There are four conveyor belts on the conveyor 154. Both sides of the two support plates 153 in the same group that are close to each other are connected with two vertical guide rods 155. The two vertical guide rods 155 on the same support plate 153 are symmetrically arranged left and right. A lifting plate 156 is slidably connected to the four vertical guide rods 155. Both sides of the two support plates 153 in the same group that are close to each other are installed with a lead screw motor two 157. The lead screw of the lead screw motor two 157 is threadedly connected to the lifting plate 156. Three lifting plates 158 are evenly spaced and bolted to the top of the lifting plate 156. Each lifting plate 158 is respectively located between two adjacent conveyor belts on the conveyor 154. Electric push rods 159 are bolted to both the left and right sides of the inner top of the bracket 2. Pressing plates 1510 are bolted to the movable ends of the electric push rods 159. Four pressing blocks 1511 are bolted to the bottom of each pressing plate 1510. The four pressing blocks 1511 are respectively arranged on the front, back, left and right sides of the bottom of the pressing plate 1510. The four pressing blocks 1511 apply pressure to the control main board evenly, which can effectively prevent the control main board from warping. Two telescopic rods 1512 are connected to both the left and right sides of the inner top of the bracket 2. The lower ends of the telescopic rods 1512 are connected to the top of the pressing plate 1510. When the pressing plate 1510 moves downward, the telescopic rods 1512 extend. When the pressing plate 1510 moves upward, the telescopic rods 1512 shorten. The telescopic rods 1512 can guide the pressing plate 1510 to make the movement of the pressing plate 1510 more stable.

[0034] Refer to Figure 1 , Figure 8 and Figure 9The cooling mechanism includes a mounting block 161, a hard tube 162, a liquid guide tube 163, a nozzle 164, a connecting tube 165 and a baffle 166. The mounting block 161 is connected to the slider 8 by bolts, the bottom of the mounting block 161 is connected to the hard tube 162, the left and right sides of the bottom of the hard tube 162 are connected to the liquid guide tube 163, the lower part of the liquid guide tube 163 is connected to the nozzle 164, the hard tube 162 is connected to the connecting tube 165, the connecting tube 165 slides through the mounting box 6, and the sides of the mounting boxes 6 on the front and rear sides away from each other are connected to the baffle 166 by bolts. The baffle 166 is made of transparent material, and the grinding condition of the control mainboard can be observed through the baffle 166. The baffle 166 can be removed to adjust the distance between the two chamfering wheels 172.

[0035] Reference Figure 4 The chamfering mechanism includes a rotating shaft 171 and a chamfering wheel 172. The bottom of the mounting frame 10 is rotatably connected to the rotating shaft 171. The output shaft of the driving motor 11 and the rotating shaft 171 are driven by a pulley set. The upper and lower parts of the rotating shaft 171 are connected to the chamfering wheels 172 by screws. The chamfering wheels 172 are connected to the rotating shaft 171 by screws. By loosening the screws, the chamfering wheels 172 can be loosened and the distance between the two chamfering wheels 172 can be adjusted. The distance between the two chamfering wheels 172 can be adjusted according to the thickness of the control mainboard.

[0036] The staff places the control main board on the conveyor 154 on the left. The conveyor 154 on the left transports the control main board to the right, transports the control main board between the two mounting boxes 6 on the left, and then controls the screw motor two 157 to drive the lifting plate 156 to move upward. The lifting plate 156 drives the lifting plate 158 to move upward, lifting the control main board so that the control main board is flush with the rubber ring 14. Then, control the movable end of the electric push rod 159 to extend, driving the pressing plate 1510 to move downward. The pressing plate 1510 drives the pressing block 1511 to move downward, pressing the control main board so that the control main board cannot move, ensuring that the control main board can smoothly enter the mounting box 6. Subsequently, the double-shaft motor 4 on the left drives the driving screw rod 5 on the left to rotate, driving the two sliding plates 3 on the left to move towards each other, thereby driving the two mounting boxes 6 on the left to move towards each other. The control main board will pass through the rubber ring 14 and extend into the mounting box 6 and contact the grinding wheel 12. The output shaft of the driving motor 11 drives the grinding wheel 12 to rotate, and the grinding wheel 12 can grind the front and back sides of the control main board. The control screw motor one 9 drives the slider 8 to move to the right. The slider 8 drives the grinding wheel 12 to move to the right, enabling the grinding wheel 12 to grind other areas on the front and back sides of the control main board. The slider 8 moving to the right can also drive the chamfering wheel 172 to move to the right. The chamfering wheel 172 will contact the edges of the control main board. The output shaft of the driving motor 11 drives the rotating shaft 171 to rotate through the pulley group. The rotating shaft 171 drives the chamfering wheel 172 to rotate, and the chamfering wheel 172 can chamfer the edges of the control main board. The staff can externally connect the connecting pipe 165 to the coolant. The coolant flows into the hard pipe 162 and the liquid guide pipe 163 through the connecting pipe 165. Subsequently, the coolant is sprayed out through the nozzle 164, spraying onto the grinding wheel 12, the chamfering wheel 172, and the control main board to cool the grinding wheel 12, the chamfering wheel 172, and the control main board. The mounting plate 13 can block the coolant and debris. The rubber ring 14 can seal the gap between the control main board and the mounting plate 13, thereby preventing the coolant and debris from flying onto the control main board. Therefore, the polished control main board does not require subsequent cleaning, thus saving resources. After the control main board is polished, the double-shaft motor 4 on the left drives the driving screw rod 5 on the left to rotate in the reverse direction, thereby driving the two mounting boxes 6 on the left to move away from each other. The polished control main board will move out of the mounting box 6. The part of the control main board located inside the mounting box 6 may be splashed with coolant and debris. When the polished control main board moves out of the mounting box 6, the rubber ring 14 can scrape off the coolant and debris, preventing the coolant and debris from remaining on the polished control main board. After the polished control main board moves out of the mounting box 6, the movable end of the electric push rod 159 is shortened, driving the pressing block 1511 to move upward. The pressing block 1511 is separated from the polished control main board. Then, control the screw motor two 157 to drive the lifting plate 158 to move downward, placing the polished control main board back on the conveyor 154.The conveyor 154 conveys the polished control main board to the right and transports the polished control main board to the conveyor 154 on the rotating plate 151. The output shaft of the reduction motor 152 drives the rotating plate 151 to rotate, thereby driving the polished control main board to rotate 90 degrees to turn the polished control main board. Then, repeat the above operation to extend the left and right sides of the control main board into the two installation boxes 6 on the right side, so as to polish and chamfer the left and right sides of the control main board. Conveying devices can be arranged on the left and right sides of the frame 1. The unpolished control main board is conveyed to the conveyor 154 through the conveying device for loading, and then the conveyor 154 conveys the polished control main board to the conveying device for discharging, continuously polishing the control main board, thereby improving work efficiency.

[0037] Refer to Figure 10 and Figure 11 It further includes a discharging mechanism. The discharging mechanism includes a collection box 181, a discharge pipe 182 and a filtering component. Collection boxes 181 are bolted to the bottoms of the installation boxes 6, and the installation boxes 6 are in communication with the collection boxes 181. The left and right sides of the inner bottom of the installation box 6 are both inclined, so that the coolant and debris can flow into the collection box 181 along the inclined position of the inner bottom of the installation box 6. Discharge pipes 182 are connected to the bottoms of the collection boxes 181. The coolant and debris will fall into the collection box 181, and the filtering component is used to filter the debris, and the coolant is discharged through the discharge pipe 182.

[0038] Refer to Figure 11 The filtering component includes a supporting plate 183, a return plate 184 and a filter bag 185. Supporting plates 183 are connected to the left and right sides inside the collection box 181. A return plate 184 is placed on the two supporting plates 183 in the same collection box 181, and filter bags 185 are connected to the bottoms of the return plate 184.

[0039] The coolant and debris will fall into the filter bag 185. The filter bag 185 filters the debris, and the coolant passes through the filter bag 185 and falls down. Then the coolant is discharged through the discharge pipe 182, which can recycle the coolant to save resources. The collection box 181 can be disassembled to facilitate the treatment of the debris in the filter bag 185.

[0040] Refer to Figure 12 It further includes a positioning mechanism. The positioning mechanism includes a connecting plate 191, a sliding rod 192, a positioning plate 193 and a screw rod 194. Connecting plates 191 are bolted to the tops of the support plates 153. The left and right parts of the connecting plate 191 are both slidably connected with sliding rods 192. A positioning plate 193 is jointly connected to the two sliding rods 192 on the same connecting plate 191. The middle parts of the connecting plate 191 are both threadedly connected with screw rods 194, and the screw rods 194 are rotatably connected to the positioning plate 193.

[0041] The staff can rotate the screw rod 194 to drive the positioning plate 193 to move and adjust the distance between the two positioning plates 193. The distance between the two positioning plates 193 can be adjusted according to the width of the control main board. After the control main board is conveyed onto the conveyor 154, the positioning plate 193 can position the control main board to prevent the position of the control main board from shifting or tilting, ensuring that the control main board can smoothly enter the installation box 6.

[0042] Referring to Figure 1 and Figure 13 , it further includes a correction mechanism. The correction mechanism includes a vision camera 201 and a controller 202. The vision cameras 201 are installed at the middle of the bottom of the pressing plates 1510 through bolts. The vision cameras 201 are located between the four pressing blocks 1511. The controller 202 is installed at the left part of the front side of the bracket 2 through bolts. Both the conveyor 154 and the vision camera 201 are electrically connected to the controller 202.

[0043] After the control main board is conveyed onto the conveyor 154, the vision camera 201 captures the control main board and sends a signal to the controller 202. If the position of the control main board is inaccurate, the controller 202 will control the conveyor 154 to work, driving the control main board to move left and right to correct the position of the control main board, ensuring that the control main board can smoothly enter the installation box 6.
