Description

Technical Field

[0001] The utility model relates to the technical field of PCB board production, and particularly relates to an edge grinding device for PCB board production. Background Art

[0002] A PCB board is a type of electronic circuit board. It is a base board made of insulating materials, on which circuit patterns are processed through printing, etching, or other manufacturing processes to provide electrical connections between electronic components. The PCB board is an indispensable part of modern electronic devices. It can achieve the efficient layout and compact arrangement of electronic components while ensuring the stability and reliability of the circuit. On the PCB board, the following several layers of structures are usually included: core board, copper film, copper clad laminate, solder mask layer, and character layer.

[0003] At present, during the production process of PCB boards, it is necessary to grind the edges of the boards. The main purpose is to remove burrs, sharp edges, and uneven parts generated during cutting or forming to ensure that the edges of the PCB boards are smooth, flat, and safe. At the same time, it prevents stress concentration and improves the assembly accuracy, etc. When grinding the edges of PCB boards of different sizes, generally manual operation is carried out. Manual operation will reduce the accuracy of grinding and may also damage the PCB board, thus reducing the efficiency of edge grinding. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an edge grinding device for PCB board production to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0006] An edge grinding device for PCB board production includes a support table and a housing. The housing is located above the support table and is fixedly connected to the support table. A rotating door is rotatably connected to one side of the housing, and a handle is fixedly connected to the rotating door. A first motor is fixedly connected to the side of the housing away from the rotating door, a second motor is fixedly connected to one side of the housing, a control panel is fixedly connected to the side of the housing away from the second motor, a viewing window is arranged at the upper end of the housing, an air outlet pipe is fixedly connected to the bottom of the housing, a blower is fixedly connected inside the air outlet pipe, an air inlet pipe is fixedly connected above the housing, a clamping component for clamping the PCB board is connected inside the housing, a moving component for controlling the movement of the clamping component is connected inside the housing, and a grinding component for controlling the movement of the grinding device is connected inside the housing.

[0007] When the PCB board needs to be edge-ground, start the first motor. The first motor drives the moving component to make the clamping component move to the rotating door. Then, adjust the clamping component so that it can adapt to the size of the PCB board. Then, clamp the PCB board. Next, move the PCB board to a suitable position through the moving component. At this time, start the second motor to drive the grinding component to move, thereby grinding the PCB board. The first motor and the second motor can be controlled through the control panel, so that the moving component and the grinding component cooperate with each other to complete the edge-grinding work of the PCB board. At the same time, the blower works to discharge the waste chips generated by grinding. This can not only improve the accuracy of grinding PCB boards of different sizes, but also reduce the probability of PCB board damage, thereby improving the working efficiency of PCB board edge-grinding.

[0008] A further improvement of the technical solution of the present utility model lies in that: the moving component includes a first lead screw. The first lead screw is rotatably connected to the housing. A first limit block is rotatably connected to the outside of the first lead screw. The first limit block is fixedly connected to the housing. The first limit blocks are symmetrically arranged. One end of the first lead screw is fixedly connected to the output end of the first motor. A moving block is threadedly connected to the first lead screw. The moving block is slidably connected to the first limit block. A slide bar is fixedly connected to the side of the housing far from the first lead screw. The slide bar is fixedly connected to the housing. A fixed block is slidably connected to the slide bar. The fixed block is slidably connected to the first limit block.

[0009] Adopting the above technical solution, when the moving component works in this solution, the first motor rotates to drive the first lead screw fixedly connected to its output end to rotate. The rotation of the first lead screw cooperates with the first limit block to make the moving block move along the axis direction of the first lead screw. The movement of the moving block will drive the fixed block to slide on the slide bar through the clamping component, thereby achieving the purpose of moving and clamping the component. When the clamping component clamps the PCB board, at this time, the first motor can be rotated to drive the clamping component to adjust the position, so that the grinding component can grind the edge of the PCB board.

[0010] A further improvement of the technical solution of the present utility model lies in that: the clamping component includes a bottom plate, one end of the bottom plate is fixedly connected to the moving block, the other end of the bottom plate is fixedly connected to the fixed block, a slide rail is fixedly connected above the bottom plate, sliding blocks are symmetrically arranged and slidably connected in the slide rail, a stop block is fixedly connected below the sliding block, a fixing plate is fixedly connected to the side of the slide rail away from the first motor, the fixing plates are symmetrically arranged, and a bidirectional lead screw is rotatably connected to the symmetrically arranged fixing plates through damping rotating shafts. The stop block is threadedly connected to the bidirectional lead screw, and knobs are respectively fixedly connected to both ends of the bidirectional lead screw. A first clamping plate is fixedly connected above the sliding block, the first clamping plate is L-shaped, a second clamping plate is slidably connected above the first clamping plate, a bolt is rotatably connected to the first clamping plate, the bolt is threadedly connected to the second clamping plate, and clamping parts for increasing the friction between the first clamping plate and the second clamping plate and the PCB board are connected to the opposite side surfaces of the first clamping plate and the second clamping plate.

[0011] With the above technical solution, when it is necessary to polish PCB boards of different sizes in this solution, first twist the knob at this time. The knob drives the bidirectional lead screw to rotate, and the rotation of the bidirectional lead screw will drive the sliding block to slide on the slide rail, so as to adjust to the appropriate size. Then place the PCB board between the first clamping plate and the second clamping plate. Because the first clamping plate and the second clamping plate slide relative to each other, twist the bolt on the first clamping plate, so that the second clamping plate moves to clamp the PCB board. Clamping parts are arranged on the opposite side surfaces of the first clamping plate and the second clamping plate, which can increase the friction between the clamping component and the PCB board, and at the same time effectively protect the PCB board and prevent the PCB board from being damaged.

[0012] A further improvement of the technical solution of the present utility model lies in that: the polishing component includes a polishing machine. A second limiting block is fixedly connected to the side of the inside of the housing close to the first motor. A second lead screw is arranged inside the second limiting block, and the second lead screw is rotatably connected to the housing. The end of the second lead screw away from the first motor is fixedly connected to the output end of the second motor. A base is threadedly connected to the second lead screw, and the base is slidably connected to the second limiting block. The polishing machine is fixedly connected to the base.

[0013] With the above technical solution, in this solution, because the edge of the PCB board needs to be ground, when the first motor and the second motor cooperate to work through the control component and the PCB board moves to the appropriate position, the polishing machine starts to work to grind the edge of the PCB board. The second motor drives the second lead screw fixedly connected to its output end to rotate and cooperate with the second limiting block to make the base move along the axis direction of the second lead screw, so as to grind the edge of the PCB board.

[0014] A further improvement of the technical solution of the present utility model lies in that: the clamping part includes a friction layer, and the material of the friction layer is rubber.

[0015] Adopting the above technical solution, in this solution, by providing a friction layer, the frictional force between the first clamping plate and the second clamping plate and the PCB board can be increased, thereby improving the fixing effect on the PCB board and preventing the PCB board from shifting during the grinding process.

[0016] A further improvement of the technical solution of the present utility model lies in that: a groove is provided on the side of the second clamping plate close to the first clamping plate.

[0017] Adopting the above technical solution, in this solution, by providing a groove on the side of the second clamping plate close to the first clamping plate, the fixing effect between the second clamping plate and the PCB board is improved.

[0018] A further improvement of the technical solution of the present utility model lies in that: a filter screen is fixedly connected inside the air inlet pipe.

[0019] Adopting the above technical solution, in this solution, by providing a filter screen, dust in the external air can be prevented from entering the housing, thereby affecting the grinding accuracy of the PCB board.

[0020] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0021] 1. The present utility model provides an edge grinding device for PCB board production. When edge grinding of the PCB board is required, the first motor is started. The first motor drives the moving component to make the clamping component move to the rotating door. Then, by adjusting the clamping component, the clamping component can be adapted to the size of the PCB board. Then the PCB board is clamped, and then the PCB board is moved to a suitable position through the moving component. At this time, the second motor is started to drive the grinding component to move so as to grind the PCB board. The first motor and the second motor can be controlled through the control panel, so that the moving component and the grinding component cooperate with each other, thereby completing the edge grinding work of the PCB board. At the same time, the blower works to discharge the waste chips generated by grinding. This can not only improve the accuracy of grinding PCB boards of different sizes, but also reduce the probability of damage to the PCB board, thereby improving the working efficiency of PCB board edge grinding.

[0022] 2. The present utility model provides an edge grinding device for PCB board production. When the moving component works, the first motor rotates to drive the first lead screw fixedly connected to its output end to rotate. The rotation of the first lead screw cooperates with the first limit block to make the moving block move along the axis direction of the first lead screw. The movement of the moving block will drive the fixed block to slide on the sliding rod through the clamping component, thereby achieving the purpose of moving the clamping component. When the clamping component clamps the PCB board, at this time, the position of the clamping component can be adjusted by rotating the first motor, so that the grinding component can grind the edge of the PCB board.

[0023] 3. The utility model provides an edge grinding device for PCB board production. When grinding PCB boards of different sizes, first turn the knob. The rotation of the knob drives the bidirectional lead screw to rotate, and the rotation of the bidirectional lead screw drives the slider to slide on the slide rail, so as to adjust to the appropriate size. Then place the PCB board between the first clamping plate and the second clamping plate. Since the first clamping plate and the second clamping plate slide relative to each other, turn the bolt on the first clamping plate to move the second clamping plate to clamp the PCB board. A clamping part is arranged on the surface of the first clamping plate and the second clamping plate facing each other, which can increase the friction between the clamping component and the PCB board, and at the same time effectively protects the PCB board and prevents the PCB board from being damaged.

Detailed Description of the Embodiments

[0031] The following further describes the present utility model in detail with reference to the embodiments:

[0032] Embodiment 1

[0033] As Figure 1 , Figure 2As shown in the figure, the utility model provides an edge grinding device for PCB board production, which includes a support table 1 and a housing 2. The housing 2 is located above the support table 1 and is fixedly connected to the support table 1. A rotating door 3 is rotatably connected to one side of the housing 2, and a handle 4 is fixedly connected to the rotating door 3. A first motor 5 is fixedly connected to the side of the housing 2 away from the rotating door 3, a second motor 6 is fixedly connected to one side of the housing 2, and a control panel 7 is fixedly connected to the side of the housing 2 away from the second motor 6. A viewing window 8 is arranged at the upper end of the housing 2, and an air outlet pipe is fixedly connected to the bottom of the housing 2. A blower is fixedly connected inside the air outlet pipe. An air inlet pipe is fixedly connected above the housing 2. A clamping component for clamping the PCB board is connected inside the housing 2, a moving component for controlling the movement of the clamping component is connected inside the housing 2, and a grinding component for controlling the movement of the grinding device is connected inside the housing 2.

[0034] In this embodiment, when edge grinding of the PCB board is required, the first motor 5 is started. The working of the first motor 5 drives the moving component to move the clamping component to the rotating door 3. Then, by adjusting the clamping component, the clamping component can be adapted to the size of the PCB board. Then, the PCB board is clamped, and then the PCB board is moved to a suitable position through the moving component. At this time, the second motor 6 is started to drive the grinding component to move so as to grind the PCB board. The first motor 5 and the second motor 6 can be controlled through the control panel 7, so that the moving component and the grinding component cooperate with each other, thereby completing the edge grinding work of the PCB board. At the same time, the blower works to discharge the waste chips generated during grinding. This can not only improve the precision of grinding PCB boards of different sizes, but also reduce the probability of PCB board damage, thereby improving the working efficiency of PCB board edge grinding.

[0035] As Figure 3 shown in the figure, in this embodiment, preferably, the moving component includes a first lead screw 9. The first lead screw 9 is rotatably connected to the housing 2. A first limit block 10 is rotatably connected to the outside of the first lead screw 9. The first limit block 10 is fixedly connected to the housing 2. The first limit blocks 10 are symmetrically arranged. One end of the first lead screw 9 is fixedly connected to the output end of the first motor 5. A moving block 11 is threadedly connected to the first lead screw 9. The moving block 11 is slidably connected to the first limit block 10. A slide bar 12 is fixedly connected to the side of the housing 2 away from the first lead screw 9. The slide bar 12 is fixedly connected to the housing 2. A fixed block 13 is slidably connected to the slide bar 12. The fixed block 13 is slidably connected to the first limit block 10.

[0036] When the moving part is working, the first motor 5 rotates to drive the first lead screw 9 fixedly connected to its output end to rotate. The rotation of the first lead screw 9 cooperates with the first limit block 10 to make the moving block 11 move along the axis direction of the first lead screw 9. The movement of the moving block 11 will drive the fixed block 13 to slide on the slide bar 12 through the clamping part, so as to achieve the purpose of moving the clamping part. When the clamping part clamps the PCB board, at this time, the first motor 5 can be rotated to drive the clamping part to adjust the position, so that the grinding part can grind the edge of the PCB board.

[0037] As Figure 1 , Figure 4 shown, preferably, the clamping part includes a bottom plate 14. One end of the bottom plate 14 is fixedly connected to the moving block 11, and the other end of the bottom plate 14 is fixedly connected to the fixed block 13. A slide rail 15 is fixedly connected above the bottom plate 14. Two sliders 16 are symmetrically arranged and slidably connected in the slide rail 15. A stopper 17 is fixedly connected below the slider 16. A fixed plate is fixedly connected to the side of the slide rail 15 away from the first motor 5. The fixed plates are symmetrically arranged. A bidirectional lead screw 18 is rotatably connected to the symmetrically arranged fixed plates through damping rotating shafts. The stopper 17 is threadedly connected to the bidirectional lead screw 18. Knobs 19 are fixedly connected to both ends of the bidirectional lead screw 18 respectively. A first clamping plate 20 is fixedly connected above the slider 16. The first clamping plate 20 is L-shaped. A second clamping plate 21 is slidably connected above the first clamping plate 20. A bolt 22 is rotatably connected to the first clamping plate 20. The bolt 22 is threadedly connected to the second clamping plate 21. Clamping parts for increasing the friction between the first clamping plate 20 and the second clamping plate 21 and the PCB board are connected to the surfaces of the first clamping plate 20 and the second clamping plate 21 facing each other.

[0038] When it is necessary to grind PCB boards of different sizes, first twist the knob 19 at this time. The knob 19 drives the bidirectional lead screw 18 to rotate. The rotation of the bidirectional lead screw 18 will drive the slider 16 to slide on the slide rail 15, so as to adjust to a suitable size. Then place the PCB board between the first clamping plate 20 and the second clamping plate 21. Because the first clamping plate 20 and the second clamping plate 21 slide relative to each other, twist the bolt 22 on the first clamping plate 20, so that the second clamping plate 21 moves to clamp the PCB board. Clamping parts are arranged on the surfaces of the first clamping plate 20 and the second clamping plate 21 facing each other, which can increase the friction between the clamping part and the PCB board, and at the same time effectively protect the PCB board and prevent the PCB board from being damaged.

[0039] As Figure 3As shown, preferably, the grinding component includes a grinding machine 23. A second limiting block 24 is fixedly connected to one side of the interior of the housing 2 close to the first motor 5. A second lead screw 25 is arranged inside the second limiting block 24. The second lead screw 25 is rotatably connected to the housing 2. One end of the second lead screw 25 away from the first motor 5 is fixedly connected to the output end of the second motor 6. A base 26 is threadedly connected to the second lead screw 25. The base 26 is slidably connected to the second limiting block 24. The grinding machine 23 is fixedly connected to the base 26.

[0040] Because the edge of the PCB board needs to be ground, when the first motor 5 and the second motor 6 cooperate to work through the control component, the PCB board moves to a suitable position. At this time, the grinding machine 23 starts to work to grind the edge of the PCB board. The second motor 6 works to drive the second lead screw 25 fixedly connected to its output end to rotate and cooperate with the second limiting block 24 to make the base 26 move along the axis direction of the second lead screw 25, so as to perform the work of grinding the edge of the PCB board.

[0041] As Figure 5 shown, preferably, the clamping part includes a friction layer 27, and the material of the friction layer 27 is rubber.

[0042] By providing the friction layer 27, the friction force between the first clamping plate 20 and the second clamping plate 21 and the PCB board can be increased, thereby improving the fixing effect on the PCB board and preventing the PCB board from shifting during the grinding process.

[0043] As Figure 2 shown, preferably, a filter screen 29 is fixedly connected inside the air inlet pipe.

[0044] By providing the filter screen 29, dust in the external air can be prevented from entering the housing 2, thereby affecting the grinding accuracy of the PCB board.

[0045] Embodiment 2

[0046] As Figure 5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: preferably, a groove 28 is provided on the side of the second clamping plate 21 close to the first clamping plate 20.

[0047] In this embodiment, by providing the groove 28 on the side of the second clamping plate 21 close to the first clamping plate 20, the fixing effect between the second clamping plate 21 and the PCB board is improved.

[0048] Next, the working principle of the edge grinding device for PCB board production will be specifically described.

[0049] As Figures 1-5As shown, when the PCB board needs to be edge-ground, the first motor 5 is started. The first motor 5 drives the moving component to make the clamping component move to the rotating door 3. Then, the clamping component is adjusted to fit the size of the PCB board. Then, the PCB board is clamped. Then, the PCB board is moved to a suitable position by the moving component. At this time, the second motor 6 is started to drive the grinding component to move to grind the PCB board. The first motor 5 and the second motor 6 can be controlled through the control panel 7, so that the moving component and the grinding component cooperate with each other to complete the edge-grinding work of the PCB board. At the same time, the blower works to discharge the waste chips generated by grinding. This can not only improve the accuracy of grinding PCB boards of different sizes, but also reduce the probability of PCB board damage, thus improving the working efficiency of PCB board edge-grinding. When the moving component works, the first motor 5 rotates to drive the first lead screw 9 fixedly connected to its output end to rotate. The rotation of the first lead screw 9 cooperates with the first limit block 10 to make the moving block 11 move along the axis direction of the first lead screw 9. The movement of the moving block 11 drives the fixed block 13 to slide on the slide bar 12 through the clamping component, so as to achieve the purpose of moving the clamping component. When the clamping component clamps the PCB board, at this time, the first motor 5 can be rotated to drive the clamping component to adjust the position, so that the grinding component can grind the edge of the PCB board. When grinding PCB boards of different sizes, first twist the knob 19. The knob 19 drives the bidirectional lead screw 18 to rotate. The rotation of the bidirectional lead screw 18 drives the slider 16 to slide on the slide rail 15, so as to adjust to a suitable size. Then, the PCB board is placed between the first clamping plate 20 and the second clamping plate 21. Because the first clamping plate 20 and the second clamping plate 21 slide relative to each other, twist the bolt 22 on the first clamping plate 20 to make the second clamping plate 21 move to clamp the PCB board. A clamping part is arranged on the opposite side surface of the first clamping plate 20 and the second clamping plate 21 to increase the friction between the clamping component and the PCB board, and at the same time effectively protects the PCB board to prevent the PCB board from being damaged. Because the PCB board needs to be edge-ground, when the first motor 5 and the second motor 6 are made to cooperate through the control component, the PCB board moves to a suitable position. At this time, the grinding machine 23 starts to work to grind the edge of the PCB board. The second motor 6 works to drive the second lead screw 25 fixedly connected to its output end to rotate and cooperate with the second limit block 24 to make the base 26 move along the axis direction of the second lead screw 25, so as to grind the edge of the PCB board. By providing a friction layer 27, the friction between the first clamping plate 20 and the second clamping plate 21 and the PCB board can be increased, so as to improve the fixing effect on the PCB board and prevent the PCB board from shifting during the grinding process. By providing a groove 28 on the side of the second clamping plate 21 close to the first clamping plate 20, the fixing effect between the second clamping plate 21 and the PCB board is improved.By providing a filter screen 29, dust in the external air can be prevented from entering the housing 2, thus affecting the polishing accuracy of the PCB board.

[0050] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
