Furthermore, the cleaning brush will not develop gaps with the conveyor belt due to wear, ensuring effective and efficient debris removal.

[0004] During PCB manufacturing and drilling, it was found that because the size of general PCB drilling machines is relatively uniform, it is inconvenient to clamp and fix the PCB when processing PCBs of different sizes, and it will also cause problems with quick and accurate positioning. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, when drilling PCB printed circuit boards, the size of general PCB drilling machines is relatively uniform, making it inconvenient to clamp and fix the PCB boards when processing PCB boards of different sizes, and also resulting in the inability to quickly and accurately position them.

[0006] To solve the above technical problems, this utility model provides a PCB board enlargement device with a positioning mechanism, comprising: a processing base, an operating frame mounted on one side of the surface of the processing base, a control box mounted on one side of the operating frame, a drilling module mounted on the upper surface of the operating frame, a support frame positioned on the surface of the processing base corresponding to the drilling module, positioning devices on both sides of the surface of the support frame, the positioning device comprising two support plates, the lower surfaces of the two support plates being fixedly connected to the surface of the support frame, the surfaces of the two support plates being rotatably connected to the same drive shaft, both ends of the drive shaft being fixedly connected to rotating shafts, the arc surfaces of both ends of the drive shaft being threaded with threads in opposite directions, the arc surfaces of both ends of the drive shaft being threadedly connected to moving rings, the arc surfaces of the moving rings being fixedly connected to positioning blocks, the positioning blocks having an "L" shaped cross-section.

[0007] The effect achieved by the above components is as follows: during the process of processing and enlarging the PCB board, in order to facilitate the fixing and limiting of the PCB board position, the positioning device set on the surface of the support frame can be used for assistance. By adjusting the position of the positioning block, it is helpful to clamp and position PCB boards of different sizes.

[0008] Preferably, the arc surface of the rotating shaft is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly distributed on the arc surface of the rotating shaft.

[0009] The effect achieved by the above components is that the anti-slip grooves enable quick and easy deflection of the shaft, which helps to increase friction.

[0010] Preferably, a guide rail is fixedly connected to the surface of the support frame at the position corresponding to the drive shaft, and a limit rod is fixedly connected to the lower surface of the moving ring, with the bottom arc surface of the limit rod slidably connected to the inner wall surface of the guide rail.

[0011] The effect achieved by the above components is that when the moving ring moves horizontally, the sliding position of the entire moving ring and the positioning block can be limited by the sliding between the limiting rod and the guide rail.

[0012] Preferably, a scale plate is fixedly connected to the surface of the support frame at the position corresponding to the guide rail, and the length of the scale plate is adapted to the length of the drive shaft.

[0013] The effect achieved by the above components is that, during the process of moving and adjusting the positioning blocks, the scale plate set on the surface of the support frame can be used for assistance, which facilitates the precise control of the distance between the two positioning blocks.

[0014] Preferably, the surface of the support frame is provided with an auxiliary device, which includes a pad and an insert block. The lower surface of the pad is slidably connected to the inner wall of the support frame. A through groove is formed on one side surface of the support frame. Connecting rods are fixedly connected to both sides of the inner wall of the through groove. The arc surfaces of the two connecting rods slide through one end of the insert block. A spring is sleeved on the arc surface of the connecting rod. The two ends of the spring are fixedly connected to the connecting rod and the insert block, respectively. An insert groove is formed on the side wall surface of the pad. The inner wall of the insert groove is inserted into one end surface of the insert block.

[0015] The effect achieved by the above components is as follows: when supporting the PCB board with the support frame, in order to avoid the surface of the support frame being subjected to mechanical pressure for a long time, the pads inside the support frame can be replaced with the help of auxiliary devices, so as to better position and support the PCB board for hole enlargement operations.

[0016] Preferably, a pull ring is rotatably connected to the side surface of the insert block away from the support frame, and the pull ring has a vertical cross-section.

[0017] The effect achieved by the above components is that the position of the insert can be adjusted with the help of the pull ring.

[0018] Preferably, a limiting block is fixedly connected to the inner wall surface of the support frame, a limiting groove is formed on the lower surface of the pad, the inner wall of the limiting groove is slidably connected to the surface of the limiting block, and the cross-section of the limiting block is inverted triangular.

[0019] The effect achieved by the above components is that when the pads inside the support frame are replaced and the limiting position is adjusted, the pads can be fixed and protected by the insertion and fixing between the limiting block and the limiting groove, so as to prevent the pads from sliding and falling off.

[0020] Compared with related technologies, the PCB board hole enlargement device with a positioning mechanism provided by this utility model has the following beneficial effects:

[0021] This utility model provides a PCB board enlargement device with a positioning mechanism. By operating the positioning device, the drive shaft is rotated, thereby allowing the drive shaft to drive the moving rings on both ends of the arc surface to adjust the spacing. At this time, the moving rings will drive the positioning block to perform clamping and limiting operations on the PCB board to be processed, which helps to better fix the entire PCB board when enlarging holes.

[0022] By operating the auxiliary mechanism, the position of the pad can be limited for replacement. With the help of the through groove set on the side wall surface of the support frame, the insert block that moves and inserts in the through groove can be inserted and fixed with the insert groove opened on the side wall of the replaced pad. This helps to limit the replacement of the pad after long-term use and enables stable hole enlargement operation on the PCB board. Attached Figure Description

The arc surface of the bottom end of the limit rod 46 is slidably connected to the inner wall surface of the guide rail 47. The surface of the support frame 7 is fixedly connected to the scale plate 48 at the position corresponding to the guide rail 47.

[0032] In the embodiments of this utility model, please refer to Figure 2 and Figure 4 The auxiliary device 5 includes a pad 51 and an insert block 59. The lower surface of the pad 51 is slidably connected to the inner wall of the support frame 7. A through groove 54 is opened on one side surface of the support frame 7. Connecting rods 55 are fixedly connected to both sides of the inner wall of the through groove 54. The arc surfaces of the two connecting rods 55 slide through one end of the insert block 59.

When operating the positioning device 4, the position of the PCB board needs to be positioned first. The spacing of the positioning blocks 45 is adjusted according to the size of the PCB board. Rotating the shaft 43 at either end of the drive shaft 42 causes the drive shaft 42 to rotate, simultaneously moving the positioning blocks 45 at both ends of the drive shaft 42. The spacing can be precisely adjusted by using the scale plate 48 fixed on the upper surface of the support frame 7 until the positioning blocks 45 at the four corners of the support frame 7 clamp and fix the PCB board, and then the hole enlargement operation is performed. After long-term operation and use, the pad 51 set in the support frame 7 will need to be replaced. At this time, the lower surface of the replaced pad 51 is slidably inserted into the limiting block 52 in the support frame 7 through the limiting groove 53. Then, the pull ring 57 in the through groove 54 is pulled to stretch and limit the position of the inlay block 59 until the inlay block 59 is inserted and fixed into the inlay groove 58 opened on the side wall surface of the pad 51. At this time, the entire replaced pad 51 can be used for stable fixed and limited operation.
