Description

Technical Field

[0001] This utility model relates to the technical field of PCB board processing equipment, specifically to an edge grinding machine used in PCB board production. Background Technology

[0002] Edge grinding machines for PCB manufacturing are key pieces of equipment used for processing the shape of printed circuit boards (PCBs). Their core function is to refine the edges of the cut PCB boards. Their working principle involves using high-speed rotating grinding wheels to remove burrs, gaps, flash, and other defects from the cut edges of the PCB board, while simultaneously grinding the edges to the required smoothness and dimensional accuracy, ensuring that the edges are flat and undamaged.

[0003] However, existing edge grinding machines for PCB production are prone to localized pressure concentration during use, which can lead to edge chipping on thin PCBs and reduce the yield rate of PCB production. Therefore, we propose an edge grinding machine for PCB production to solve the above-mentioned problems. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an edge grinding machine for PCB board production, including a base, a worktable is provided at the middle position of the top surface of the base, an array of vacuum suction cups is provided on the top surface of the worktable, a vacuum pump is provided on one side of the top surface of the base, and the vacuum pump is conductively connected to the array of vacuum suction cups, and a stabilizing frame is provided on the top surface of the base and on the side of the vacuum pump.

[0006] An adjustment component is provided on the stabilizing frame and directly above the array-type vacuum suction cup. A servo motor is installed on the telescopic end of the adjustment component, and a grinding head is connected to the output end of the servo motor.

[0007] A laser profile sensor is positioned directly above the array-type vacuum suction cup, and the top of the laser profile sensor is connected to the adjustment component. A monitoring component is positioned on one side of the servo motor, and a touch screen all-in-one machine is positioned on one side of the top of the stabilizing frame.

[0009] The bottom end of the electric turntable is provided with a retaining sleeve, the inner cavity of the retaining sleeve is provided with a second electric push rod, the telescopic end of the second electric push rod is provided with a limit plate, and the bottom of the outer wall of the limit plate is provided with a mounting bracket for mounting the servo motor.

[0010] Preferably, the first electric actuator and the second electric actuator are arranged vertically.

[0011] Preferably, the top of the laser profile sensor is connected to the bottom surface of the sleeve.

[0012] Preferably, the monitoring component includes a support plate disposed on the outside of the card holder and an air pump disposed on one side of the top surface of the stabilizing frame, and a high-definition industrial camera is disposed on the inner side wall of the support plate near the bottom end;

[0013] A connecting plate is provided on one side of the support plate, and a nozzle is embedded in the connecting plate.

[0016] Beneficial effects

[0017] This invention provides an edge grinding machine for PCB board production. Compared with the prior art, it has the following advantages:

[0018] This edge grinding machine for PCB board production can be placed in a designated position via its base, providing stable support for the worktable and stabilizing frame. When edge grinding of a PCB board is required, the operator first places the PCB board on the array of vacuum suction cups located on top of the worktable. Then, through the touch screen all-in-one machine, the vacuum pump can be controlled to operate, which provides negative pressure to the array of vacuum suction cups, allowing the array of vacuum suction cups to stably adsorb and position the PCB board, preventing the PCB board from shaking during the subsequent edge grinding process. Then, through the touch screen all-in-one machine, the laser contour sensor can be controlled to scan the contour of the PCB board on the array of vacuum suction cups and send the scan data to the touch screen all-in-one machine, which can then determine the position of the PCB board's perimeter.

[0019] Next, the touch screen all-in-one machine controls the extension and retraction of the adjustment component on the stabilizing frame and the activation of the servo motor. This allows the adjustment component, driven by the servo motor, to move around the perimeter of the PCB board with a high-speed rotating grinding head. The high-speed rotating grinding head then performs edge grinding on the PCB board. During the edge grinding process, the monitoring component can capture images of the grinding area in real time and send the images to the touch screen all-in-one machine for image recognition. When a micro-crack is detected at the edge, the touch screen all-in-one machine can quickly control the operation of the adjustment component, which in turn drives the servo motor and the grinding head away from the PCB board, thereby reducing edge breakage and improving the yield rate of PCB board edge grinding.

[0025] 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.

[0026] Please see Figures 1-2This utility model provides a technical solution: an edge grinding machine for PCB board production, including a base 1, a worktable 2 disposed in the middle of the top surface of the base 1, an array of vacuum suction cups 3 disposed on the top surface of the worktable 2, a vacuum pump 4 disposed on one side of the top surface of the base 1 and the vacuum pump 4 is electrically connected to the array of vacuum suction cups 3, a stabilizing frame 5 disposed on the top surface of the base 1 and on one side of the vacuum pump 4; an adjusting component 6 disposed on the stabilizing frame 5 and directly above the array of vacuum suction cups 3, a servo motor 7 mounted on the telescopic end of the adjusting component 6, and a grinding head 8 connected to the output end of the servo motor 7; a laser contour sensor 9 disposed directly above the array of vacuum suction cups 3 and the top of the laser contour sensor 9 is connected to the adjusting component 6, a monitoring component 10 disposed on one side of the servo motor 7, and a touch screen all-in-one machine 11 disposed on one side of the top of the stabilizing frame 5;

[0027] The base 1 allows for placement in a designated location and provides stable support for the workbench 2 and the stabilizing frame 5. When edge grinding of the PCB board is required, the operator first places the PCB board on the array-type vacuum suction cup 3 located on top of the workbench 2. Then, through the touch screen all-in-one machine 11, the vacuum pump 4 can be controlled to provide negative pressure to the array-type vacuum suction cup 3, thereby ensuring that the array-type vacuum suction cup 3 stably adsorbs and positions the PCB board, preventing the PCB board from shaking during the subsequent edge grinding process. The touch screen all-in-one machine 11 can also control the laser contour sensor 9, which can scan the contour of the PCB board on the array-type vacuum suction cup 3 and send the scan data to the touch screen all-in-one machine 11, allowing the touch screen all-in-one machine 11 to determine the PCB board's shape. The touch screen 11 controls the extension and retraction of the adjustment component 6 on the stabilizing bracket 5 and the activation of the servo motor 7. This allows the adjustment component 6, driven by the servo motor 7, to move the high-speed rotating grinding head 8 around the perimeter of the PCB board. The high-speed rotating grinding head 8 then performs edge grinding on the PCB board. During the edge grinding process, the monitoring component 10 can capture images of the grinding area in real time and send the captured images to the touch screen 11 for image recognition. When a micro-crack is detected at the edge, the touch screen 11 can quickly control the adjustment component 6 to move, causing the adjustment component 6 to drive the servo motor 7 and the grinding head 8 away from the PCB board. This reduces edge breakage of the PCB board and improves the yield rate of PCB board edge grinding.

[0028] See Figures 1-3The adjustment assembly 6 includes a first electric push rod 61 disposed on one side of the top of the stabilizing frame 5. The telescopic end of the first electric push rod 61 is connected to a positioning plate 62. An electric turntable 63 is disposed on the bottom surface of the positioning plate 62. A retaining sleeve 64 is disposed at the bottom end of the electric turntable 63. A second electric push rod 65 is disposed in the inner cavity of the retaining sleeve 64. A limiting plate 66 is installed on the telescopic end of the second electric push rod 65. A mounting bracket 67 for mounting the servo motor 7 is disposed at the bottom of the outer wall of the limiting plate 66. The first electric push rod 61 and the second electric push rod 65 are distributed vertically.

[0029] By adjusting the first electric push rod 61 in component 6, it can be installed on the top side of the stabilizing frame 5, and its telescopic end can be installed on the electric turntable 63 via the positioning plate 62. Then, through the electric turntable 63, the second electric push rod 65 can be installed via the clamp 64. Then, the second electric push rod 65 can be installed on the servo motor 7 and the monitoring component 10 via the limiting plate 66 and the clamp 67. Then, by using the first electric push rod 61 and the second electric push rod 65 in conjunction with the electric turntable 63, the position, height and orientation of the servo motor 7 can be flexibly adjusted, so that the servo motor 7 can drive the grinding head 8 to perform edge grinding on the PCB board.

[0030] See Figure 2 , Figure 3 The top of the laser profile sensor 9 is connected to the bottom surface of the sleeve 64, which facilitates the installation and fixation of the laser profile sensor 9.

[0031] See Figure 2 , Figure 4 The monitoring component 10 includes a support plate 101 disposed on the outside of the card holder 67 and an air pump 102 disposed on one side of the top surface of the stabilizing frame 5. A high-definition industrial camera 103 is disposed on the inner side wall of the support plate 101 near the bottom end. A connecting plate 104 is disposed on one side of the support plate 101. A nozzle 105 is embedded in the connecting plate 104, and the air outlet of the nozzle 105 is located on the shooting end side of the high-definition industrial camera 103. The air inlet of the nozzle 105 is connected to the air outlet of the air pump 102 through a connecting pipe 106. The connecting pipe 106 is a spring tube.

[0032] The support plate 101 in the monitoring component 10 can be fixed to the outside of the card holder 67 and can also be used to install the high-definition industrial camera 103. At the same time, the nozzle 105 can be installed and fixed via the connecting plate 104. Then, the high-definition industrial camera 103 can capture the grinding area in real time and send the captured image to the touch screen all-in-one machine 11 for easy image recognition. When a micro-crack is detected at the edge, the touch screen all-in-one machine 11 can quickly control the operation of the adjustment component 6, which can drive the servo motor 7 and the grinding head 8 to the PCB board, thereby reducing the edge breakage of the PCB board and improving the yield of PCB board edge grinding. The air pump 102 can provide compressed air to the nozzle 105 through the spring tube, thereby cleaning the high-definition industrial camera 103 and ensuring the clarity of the high-definition industrial camera 103.

[0033] See Figure 2 , Figure 4 The monitoring component 10 also includes an air filter box, which is located on one side of the air pump 102. The air inlet of the air pump 102 is connected to the air outlet of the air filter box, which can filter the air drawn into the air pump 102 to prevent foreign objects from clogging the nozzle 105.

[0034] During operation, the base 1 allows the PCB board to be placed in a designated position and provides stable support for the workbench 2 and the stabilizing frame 5. When edge grinding of the PCB board is required, the operator first places the PCB board on the array-type vacuum suction cup 3 located on top of the workbench 2. Then, through the touch screen all-in-one machine 11, the operator can control the operation of the vacuum pump 4, which provides negative pressure to the array-type vacuum suction cup 3, thereby enabling the array-type vacuum suction cup 3 to stably adsorb and position the PCB board, preventing the PCB board from shaking during the subsequent edge grinding process. Then, through the touch screen all-in-one machine 11, the operator can also control the laser contour sensor 9, which can scan the contour of the PCB board on the array-type vacuum suction cup 3 and send the scan data to the touch screen all-in-one machine 11, allowing the touch screen all-in-one machine 11 to determine the PCB board's edge. Around the perimeter of the B board, the touch screen all-in-one machine 11 controls the extension and retraction of the adjustment component 6 on the stabilizing bracket 5 and the activation of the servo motor 7. This allows the adjustment component 6, driven by the servo motor 7, to move the high-speed rotating grinding head 8 around the perimeter of the PCB board. The high-speed rotating grinding head 8 then performs edge grinding on the PCB board. During the edge grinding process, the monitoring component 10 can capture images of the grinding area in real time and send the captured images to the touch screen all-in-one machine 11 for image recognition. When a micro-crack is detected at the edge, the touch screen all-in-one machine 11 can quickly control the operation of the adjustment component 6, which in turn drives the servo motor 7 and the grinding head 8 away from the PCB board, thereby reducing edge breakage of the PCB board and improving the yield rate of PCB board edge grinding.

[0035] By adjusting the first electric push rod 61 in component 6, it can be installed on the top side of the stabilizing frame 5, and its telescopic end can be installed on the electric turntable 63 via the positioning plate 62. Then, through the electric turntable 63, the second electric push rod 65 can be installed via the clamp 64. Then, the second electric push rod 65 can be installed on the servo motor 7 and the monitoring component 10 via the limiting plate 66 and the clamp 67. Then, by using the first electric push rod 61 and the second electric push rod 65 in conjunction with the electric turntable 63, the position, height and orientation of the servo motor 7 can be flexibly adjusted, so that the servo motor 7 can drive the grinding head 8 to perform edge grinding on the PCB board.

[0036] The support plate 101 in the monitoring component 10 can be fixed to the outside of the card holder 67 and can also be used to install the high-definition industrial camera 103. At the same time, the nozzle 105 can be installed and fixed via the connecting plate 104. Then, the high-definition industrial camera 103 can capture the grinding area in real time and send the captured image to the touch screen all-in-one machine 11 for easy image recognition. When a micro-crack is detected at the edge, the touch screen all-in-one machine 11 can quickly control the operation of the adjustment component 6, which can drive the servo motor 7 and the grinding head 8 to the PCB board, thereby reducing the edge breakage of the PCB board and improving the yield of PCB board edge grinding. The air pump 102 can provide compressed air to the nozzle 105 through the spring tube, thereby cleaning the high-definition industrial camera 103 and ensuring the clarity of the high-definition industrial camera 103. The air filter box can filter the air drawn into the air pump 102 to prevent foreign objects from clogging the nozzle 105.

[0037] In summary, this device can not only perform edge grinding on PCB boards, but also reduce edge breakage, thereby improving the yield rate of PCB board edge grinding.
