Description

Technical Field

[0001] This invention relates to the field of circuit board processing equipment technology, specifically to a deburring device for circuit boards after drilling, equipped with hole position detection. Background Technology

[0002] Circuit boards, also known as printed circuit boards, are core components that provide mechanical assembly support and electrical connections for various electronic systems. They are often referred to as the "mother of electronic products." Circuit board manufacturing involves drilling holes according to the circuit diagram to facilitate subsequent component installation. After drilling, deburring equipment is used to remove burrs from the holes to ensure no impurities remain for further processing. However, current deburring equipment still has the following shortcomings: First, the existing deburring equipment has poor auxiliary impurity removal performance, which makes it easy for burrs to remain in the holes when the grinding head grinds them, thus interfering with subsequent processing and causing certain defects in use. Secondly, the existing deburring equipment has poor automatic feeding performance, which causes the equipment to spend a long time loading and unloading circuit boards when processing them in batches, thus interfering with the overall processing efficiency of the equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a deburring device for circuit boards after drilling, which has hole position detection capabilities, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a deburring device for circuit boards after drilling, equipped with hole position detection, comprising a worktable, a first drive screw, and a fixed bracket. A feeding conveyor mechanism is installed on the left side of the worktable, and a discharging conveyor mechanism is installed on the right side of the worktable. A bearing bracket is fixedly installed on the top of the worktable, and a first fixed plate is symmetrically fixedly installed on the top of the bearing bracket. A first drive motor is installed on the outer side of the first fixed plate. The first drive screw is rotatably connected to the inside of the first fixed plate, and a first drive mechanism is movably connected to the outer surface of the first drive screw. A feeding mechanism is installed at the bottom left side of the first drive mechanism, and a grinding component is installed at the bottom right side of the first drive mechanism. The fixed bracket is fixedly installed at the bottom of the worktable, and an electric push rod is fixedly connected to the inner surface of the fixed bracket. A fixed mechanism is fixedly connected to the extension end of the electric push rod, and a connecting pipe is fixedly connected to the bottom of the fixed mechanism. An air pump is connected to the other end of the connecting pipe, and the air pump is fixedly installed at the bottom of the worktable.

[0005] Furthermore, the first driving mechanism includes a mounting bracket, and a guide slider is fixedly connected to the top of the mounting bracket. A first connecting mechanism is fixedly installed on the top of the guide slider. The interior of the first connecting mechanism is threadedly connected to the outer surface of the first driving screw. Meanwhile, an electric telescopic rod is embedded in the bottom of the mounting bracket. The outer surface of the guide slider is slidably connected to the inner surface of the bearing bracket.

[0006] Furthermore, the feeding mechanism includes a hollow connecting chamber, with suction cups symmetrically fixedly installed at the bottom of the hollow connecting chamber, and a vacuum pump installed at the top of the hollow connecting chamber.

[0007] Furthermore, the grinding assembly includes a connecting plate, and fixed rods are symmetrically installed on the bottom of the connecting plate. A bearing plate is fixedly installed on the bottom of the fixed rods, and a second fixed plate is symmetrically fixedly installed on the top of the bearing plate. A second drive motor is installed on the top of the bearing plate. A second drive screw is installed on the output shaft of the second drive motor through a coupling, and a grinding mechanism is movably connected to the outer surface of the second drive motor.

[0008] Furthermore, there are two sets of electric telescopic rods. The bottom of the extension end of the left electric telescopic rod is fixedly connected to the top of the hollow connecting compartment, and the bottom of the extension end of the right electric telescopic rod is fixedly connected to the top of the connecting plate.

[0009] Furthermore, the top of the fixing rod is fixedly connected to the bottom of the connecting plate, and the bottom of the fixing rod is fixedly connected to the top of the bearing plate, and the bearing plate forms a fixed structure with the connecting plate through the fixing rod.

[0010] Furthermore, the grinding mechanism includes a mounting base, and a cross-shaped slider is fixedly mounted on the top of the mounting base. A second connecting mechanism is fixedly connected to the top of the cross-shaped slider. The interior of the second connecting mechanism is threadedly connected to the outer surface of the second drive screw. Meanwhile, a grinding turntable is rotatably connected to the bottom of the mounting base. A grinding head is fixedly mounted on the bottom of the grinding turntable. Support frames are symmetrically mounted on both sides of the mounting base, and a detection camera is embedded in the bottom of the support frame.

[0011] Furthermore, the top of the mounting base is fixedly connected to the bottom of the cross-shaped slider, and the outer surface of the cross-shaped slider is slidably connected to the inner surface of the support plate. The mounting base and the support plate form a sliding structure through the cross-shaped slider.

[0012] Furthermore, the fixing mechanism includes a waste chip carrying bin, and air guide grooves are symmetrically opened on both sides of the waste chip carrying bin. An annular protective plate is fixedly installed on the inner surface of the waste chip carrying bin, and a sealing mesh is fixedly connected to the upper inner surface of the annular protective plate. Meanwhile, a carrying groove is opened at the bottom of the waste chip carrying bin, and a sealing plate is movably installed on the inner surface of the carrying groove. An adsorption plate is fixedly installed at the top of the waste chip carrying bin, and T-shaped sliders are symmetrically fixedly installed on both sides of the adsorption plate. Adsorption holes are symmetrically and equidistantly opened at the top of the adsorption plate.

[0013] Furthermore, the external dimensions of the sealing plate match the internal dimensions of the bearing groove, and the sealing plate forms an engaging structure with the waste collection bin through the bearing groove.

[0014] This invention provides a deburring device for circuit boards after drilling, equipped with hole position detection, which has the following beneficial effects: 1. This invention, through the connecting pipe, enables the suction pump to generate strong suction within the fixing mechanism during operation. The interaction between the air guide groove and the adsorption holes ensures that the circuit board to be polished, placed on the upper surface of the adsorption plate, is firmly adsorbed. As the suction pump continues to operate, significant suction is applied to each hole on the circuit board, allowing the debris generated by the polishing head to automatically fall into the waste debris collection bin for collection. This prevents burrs from the polishing head from remaining in the holes and interfering with subsequent processing. Furthermore, the adsorption plate's fixation ensures that the circuit board will not move or rotate during polishing, further ensuring the deburring efficiency of the equipment. The annular protective plate and sealing mesh also prevent vent blockage in the waste debris collection bin during debris collection, effectively extending the single-use time of the fixing mechanism.

[0015] 2. The present invention, through the setting of the guide slider and the first connecting mechanism, enables the first drive motor to drive the first drive screw to rotate, thereby driving the feeding mechanism and the grinding assembly to move laterally along the top of the worktable. At this time, the feeding mechanism, in cooperation with the feeding mechanism, automatically places the circuit board conveyed by the loading conveyor mechanism directly above the fixing mechanism to complete the loading work. Furthermore, since the feeding mechanism can also transfer the circuit board to the top of the unloading conveyor mechanism after the circuit board is processed, it can effectively enhance the automation level of the equipment and thus increase the processing safety of the equipment to a certain extent.

[0016] 3. The present invention uses a detection camera to automatically detect and process the holes after grinding and those before grinding when the mounting base drives the grinding head to grind and deburr the circuit board holes. This avoids wasting time on ineffective grinding and ensures that there are no burrs left in the holes after grinding, thus facilitating the subsequent processing of the circuit board.

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, a deburring device for circuit boards after drilling, equipped with hole position detection, includes a worktable 1, a first drive screw 7, and a fixed bracket 11. A feeding conveyor 2 is installed on the left side of the worktable 1, and a discharging conveyor 3 is installed on the right side of the worktable 1. The fixed bracket 11 is fixedly installed at the bottom of the worktable 1, and an electric push rod 12 is fixedly connected to the inner surface of the fixed bracket 11. The extension end of the electric push rod 12 is fixedly connected to a fixing mechanism 13. The fixing mechanism 13 includes a waste chip carrying bin 131, and air guide grooves 132 are symmetrically opened on both sides of the waste chip carrying bin 131. An annular protective plate 133 is fixedly installed on the inner surface of the waste chip carrying bin 131, and a sealing mesh 134 is fixedly connected to the upper inner surface of the annular protective plate 133. At the same time, a carrying groove 135 is opened at the bottom of the waste chip carrying bin 131, and the inner surface of the carrying groove 135 is movably installed. A sealing plate 136 is provided, the external dimensions of which match the internal dimensions of the bearing groove 135. The sealing plate 136 and the waste chip bearing bin 131 are connected by the bearing groove 135 to form a locking structure. The locking structure of the sealing plate 136 and the waste chip bearing bin 131 makes it easy for workers to quickly disassemble and assemble the sealing plate 136, thus providing convenience for workers to clean the burrs and waste chips collected in the waste chip bearing bin 131. An adsorption plate 137 is fixedly installed on the top of the waste chip bearing bin 131, and T-shaped sliders 138 are symmetrically fixedly installed on both sides of the adsorption plate 137. Adsorption holes 139 are symmetrically and evenly spaced on the top of the adsorption plate 137. A connecting pipe 14 is fixedly connected to the bottom of the fixing mechanism 13, and the other end of the connecting pipe 14 is connected to a vacuum pump 15, which is fixedly installed on the bottom of the workbench 1.

[0021] like Figures 1-6As shown, a feeding conveyor 2 is installed on the left side of the workbench 1, and a discharging conveyor 3 is installed on the right side of the workbench 1. A bearing bracket 4 is fixedly installed on the top of the workbench 1, and a first fixed plate 5 is symmetrically fixedly installed on the top of the bearing bracket 4. A first drive motor 6 is installed on the outer side of the first fixed plate 5. A first drive screw 7 is rotatably connected to the inside of the first fixed plate 5, and a first drive mechanism 8 is movably connected to the outer surface of the first drive screw 7. The first drive mechanism 8 includes a mounting bracket 81, and a guide slider 82 is fixedly connected to the top of the mounting bracket 81. A first connecting mechanism 83 is fixedly installed on the top of the guide slider 82, and the inside of the first connecting mechanism 83 is threaded to the outer surface of the first drive screw 7. The connection is made so that an electric telescopic rod 84 is embedded in the bottom of the mounting bracket 81. There are two sets of electric telescopic rods 84. The bottom of the extension end of the left electric telescopic rod 84 is fixedly connected to the top of the hollow connecting chamber 91, and the bottom of the extension end of the right electric telescopic rod 84 is fixedly connected to the top of the connecting plate 101. The outer surface of the guide slider 82 is slidably connected to the inner surface of the bearing bracket 4. A feeding mechanism 9 is installed on the bottom left side of the first drive mechanism 8. The feeding mechanism 9 includes the hollow connecting chamber 91. Suction cups 92 are symmetrically fixedly installed on the bottom of the hollow connecting chamber 91. A vacuum pump 93 is installed on the top of the hollow connecting chamber 91. A grinding assembly 10 is installed on the bottom right side of the first drive mechanism 8. The grinding assembly 10 includes the connecting plate 101. 01, and a fixing rod 102 is symmetrically installed on the bottom of the connecting plate 101, and a bearing plate 103 is fixedly installed on the bottom of the fixing rod 102. The top of the fixing rod 102 is fixedly connected to the bottom of the connecting plate 101, and the bottom of the fixing rod 102 is fixedly connected to the top of the bearing plate 103. The bearing plate 103 and the connecting plate 101 form a fixed structure through the fixing rod 102. By setting the bearing plate 103 and the connecting plate 101 into a fixed structure, the bearing plate 103 will not loosen when the grinding mechanism 107 performs hole switching grinding. Moreover, a second fixing plate 104 is symmetrically fixedly installed on the top of the bearing plate 103, and a second drive motor 105 is installed on the top of the bearing plate 103. The output shaft of the second drive motor 105 is connected to a second drive screw 106 via a coupling. A grinding mechanism 107 is movably connected to the outer surface of the second drive motor 105. The grinding mechanism 107 includes a mounting base 1071, and a cross-shaped slider 1072 is fixedly mounted on the top of the mounting base 1071. The top of the mounting base 1071 is fixedly connected to the bottom of the cross-shaped slider 1072, and the outer surface of the cross-shaped slider 1072 is slidably connected to the inner surface of the support plate 103. The mounting base 1071 and the support plate 103 form a sliding structure through the cross-shaped slider 1072. This sliding structure of the mounting base 1071 and the support plate 103 makes the movement of the mounting base 1071 back and forth along the bottom of the support plate 103 smoother and more stable.Furthermore, a second connecting mechanism 1073 is fixedly connected to the top of the cross-shaped slider 1072, and the interior of the second connecting mechanism 1073 is threadedly connected to the outer surface of the second drive screw 106. Simultaneously, a grinding turntable 1074 is rotatably connected to the bottom of the mounting base 1071, and a grinding head 1075 is fixedly mounted on the bottom of the grinding turntable 1074. Support frames 1076 are symmetrically mounted on both sides of the mounting base 1071, and a detection camera 1077 is embedded in the bottom of the support frame 1076.

[0022] In summary, combining Figures 1-7 As shown, the working principle of the circuit board deburring equipment with hole position detection after drilling is as follows: First, the operator transports the circuit board to be processed to the equipment through the feeding conveyor 2. Then, the controller turns on the first drive motor 6. When the first drive motor 6 starts running, it drives the first drive screw 7 to rotate inside the first fixed plate 5. At this time, through the connection of the first connecting mechanism 83 and the sliding of the guide slider 82, the mounting bracket 81 moves laterally along the bottom of the bearing bracket 4. When the feeding mechanism 9 moves to the top of the circuit board, the first drive motor 6 stops running. Then, the electric telescopic rod 84 starts running, driving the hollow connecting chamber 91 to move downward. At this time, the vacuum pump 93 starts running, causing the suction cup 92 to automatically generate suction to complete the gripping work of the circuit board. Then, the electric telescopic rod 84 runs, causing the hollow connecting chamber 91 to move the circuit board upward. Then, the first drive motor 6 starts running, causing the feeding mechanism 9 to move the circuit board to the top of the worktable 1. Then, the feeding mechanism 9 places the circuit board in the center of the worktable 1. Secondly, the vacuum pump 15 starts running, and through the cooperation of the connecting pipe 14, it causes the interior of the waste collection bin 131 to generate suction. At this time, through the cooperation of the air guide groove 132 and the adsorption hole 139, the circuit board is firmly adsorbed on the upper surface of the adsorption plate 137. Then, the electric push rod 12 in the fixed bracket 11 starts running, and through the guide sliding of the T-shaped slider 138, the adsorption plate 137 drives the circuit board to rise, thereby causing the adsorption plate 137 to push the circuit board away from the worktable 1. Since the circuit board completely covers the adsorption plate 137, when a strong suction is generated inside the waste collection bin 131, suction is generated in each hole of the circuit board. Finally, after the circuit board is fixed, the first drive motor 6 starts running, causing the feeding mechanism 9 to move back to directly above the end of the feeding conveyor mechanism 2. At this point, the grinding assembly 10 moves directly above the fixing mechanism 13. Then, the electric telescopic rod 84 starts running, driving the connecting plate 101 to descend. Next, the second drive motor 105 drives the second drive screw 106 to rotate inside the second fixing plate 104. At this time, through the connection of the second connecting mechanism 1073 and the sliding of the cross-shaped slider 1072, the mounting base 1071 moves back and forth along the bottom of the support plate 103. When the grinding head 1075 moves directly above the hole, the electric telescopic rod 84 continues to descend. At this time, with the cooperation of the grinding turntable 1074, the grinding head 1075 performs grinding and deburring processing inside the hole. Due to the suction generated inside the hole, the burrs and debris generated during grinding are automatically sucked into the debris carrying bin 131 for automatic cleaning. When the grinding head 1075 moves to the next hole to prepare for grinding, the detection camera 1077 automatically detects the ground hole to ensure that there are no burrs left inside the ground hole. This completes the burr removal work of the circuit board holes. After the burr removal work of the circuit board is completed, the processed circuit board is transferred to the top of the unloading conveyor 3 by the feeding mechanism 9 to complete the unloading work.
