It also carries signal transmission, signal reception and transmission, and power supply for electronic equipment. It is called the mother of electronic products. It uses board-based insulating materials to isolate the surface copper foil conductive layer, allowing current to flow along pre-designed routes in various components, thereby completing functions such as work, amplification, attenuation, modulation, demodulation, and encoding.

[0003] In the prior art, the circuit board drilling machine and the operating method require the circuit board to be clamped during the drilling process. However, after the traditional clamping assembly clamps the circuit board, a certain amount of vibration will be generated during the drilling process, which will cause deviations in the drilling area and damage. At the same time, the clamping state of the circuit board cannot be quickly captured, resulting in a high defective rate.

[0004] After searching, it is found that the Chinese patent literature discloses a circuit board drilling machine (publication number: CN115816549A).

At the same time, because the silicone stabilizing block has a certain vibration reduction effect, the stability of the circuit board during the drilling operation is effectively guaranteed.

[0043] By setting the first sliding block 6, during use, the first sliding block 6 moves inside the first sliding cavity 5, so as to adjust the positions of components such as the first connecting frame 11 according to the size factors of the circuit board, and when the first sliding block 6 moves, the outer wall of the first limiting protrusion 8 contacts the outer wall of the second limiting protrusion 9 to perform self-limiting, so that during the drilling process of the circuit board, it can be quickly adjusted and the operation is convenient.

[0044] The top of the first sliding block 6 is fixedly connected to a mounting frame 10 with a "concave" structure, and the top of the mounting frame 10 is fixedly connected to a first connecting frame 11 with an "L" shape structure, the inner bottom end of the first connecting frame 11 is fixedly connected to a second connecting frame 12 with a "concave" structure, and the inside of the second connecting frame 12 is rotatably connected to a resistance roller 13, the outer wall of the resistance roller 13 is coated with an insulating coating, the vertical outer wall of the first connecting frame 11 is vertically movably connected to a first movable sleeve 14, and both ends of the first movable sleeve 14 are fixedly connected to a transmission sheet, one end of the transmission sheet close to the resistance roller 13 is fixedly connected to the outer wall of the mounting cavity 15, the inner top of the mounting cavity 15 is fixedly connected to a pressure sensor 16, and the bottom end of the pressure sensor 16 is in conflict with the top of the clamping silicone protrusion 17, and the clamping silicone protrusion 17 is fixedly connected to the bottom end of the mounting cavity 15.

[0045] By setting the resistance roller 13, during use, the resistance roller 13 resists the bottom end of the circuit board, and the clamping silicone protrusion 17 is subjected to the potential energy generated by the reset spring 18 and resists the top end of the circuit board, which completes the rapid clamping and limiting of the circuit board, and after the circuit board is clamped, the silicone protrusion 17 is squeezed and clamped, so that the pressure sensor 16 will generate pressure parameter data, so that during the drilling operation of the circuit board, according to the data analysis of the pressure parameter data, if the pressure data fluctuates greatly, it can be quickly determined that the clamping is loose.

[0046] One end of the transmission sheet away from the resistance roller 13 is fixedly connected to the top of the reset spring 18, and the top of the reset spring 18 is fixedly connected to a movable sleeve rod 19, and the top of the movable sleeve rod 19 is fixedly connected to a magnetic block 20, and the top of the movable sleeve rod 19 is movably connected to the bottom end of a movable sleeve 21, and the inner top of the movable sleeve 21 is fixedly connected to an electromagnetic block 22.

[0047] By setting up the electromagnetic block 22, before limiting the circuit board and after processing, the electromagnetic block 22 can be energized and generate magnetic force by controlling it, so that the electromagnetic block 22 is adsorbed on the magnetic block 20, thereby pulling the reset spring 18 to make the first movable sleeve 14 move vertically upward, thereby driving the clamping silicone protrusion 17 to move upward synchronously, so that a certain gap is left between the bottom end of the clamping silicone protrusion 17 and the top end of the resistance roller 13, which is convenient for disassembly and assembly of the circuit board.

[0048] The front and rear ends of the movable plate 4 are fixedly connected with a transmission block 23, and the interior of the transmission block 23 is penetrated and meshed with a first transmission screw sleeve 24, and the inner side walls of the first transmission screw sleeve 24 are meshed with a first connecting screw 25, and the first connecting screws 25 are symmetrically arranged in pairs at the front and rear ends of the circuit board drilling operating table 1. The first connecting screws 25 arranged at the front and rear ends of the circuit board drilling operating table 1 are fixedly connected, and the first connecting screws 25 arranged at the front and rear ends of the circuit board drilling operating table 1 are arranged with opposite tooth structures, one end of the first connecting screw 25 on the same side is transmission connected to one end of a synchronous pulley 26, a transmission belt 27 is installed between the synchronous pulleys 26, an output pulley 28 is arranged in the middle of the synchronous pulley 26, and one end of the output pulley 28 is transmission connected to the output end of the motor.

[0049] When the position of the movable plate 4 needs to be adjusted, the output pulley 28 is driven by the motor, so that the output pulley 28 cooperates with the transmission belt 27 to drive the synchronous pulley 26 to rotate. In this way, the first connecting screw rods 25 arranged at the front end and the rear end are fixedly connected, so that all the first connecting screw rods 25 are synchronously driven to rotate. Because the teeth on the outer wall of the first connecting screw rods 25 on both sides are of opposite structures, the first transmission screw rod sleeves 24 meshingly connected to the outer wall of the first connecting screw rods 25 on both sides will drive the corresponding movable plate 4 to move through the transmission block 23, so that the movable plate 4 can move relative to or oppositely, so that the size of the circuit board can be quickly adapted.

[0050] The rear end of the circuit board drilling operation table 1 is fixedly connected to a second sliding cavity 29 with an inner side wall having a "convex" structure, and the interior of the second sliding cavity 29 is horizontally movably connected to a second sliding block 30 with a "convex" structure, the interior of the second sliding block 30 is penetrated and fixedly connected to a second transmission screw sleeve 31, and the inner side wall of the second transmission screw sleeve 31 is penetrated and meshedly connected to a second connecting screw 32, one end of the second connecting screw 32 is transmission-connected to the output end of the motor, the side wall of the second sliding block 30 is fixedly connected to a first connecting frame 33 with an "L"-shaped structure, and the first connecting frame 33 is fixedly connected to the side wall of the second sliding block 30. The top of the frame 33 is fixedly connected to a second connecting frame 34 with a "concave" structure, and the interior of the second connecting frame 34 is fixedly connected to a screw output transmission structure 35 for driving the second movable sleeve 36 to move forward and backward. The second movable sleeve 36 is movably connected to the top outer wall of the first connecting frame 33, and the bottom end of the second movable sleeve 36 is fixedly connected to a first connecting frame 37 with a "concave" structure. The inner bottom end of the first connecting frame 37 is fixedly connected to a cylinder 38, and the output end of the cylinder 38 passes through the bottom end of the first connecting frame 37 and is fixedly connected to the top of the drilling device body 39.

[0051] When it is necessary to adjust the position of the first connecting frame 33, the second connecting screw 32 is driven by the motor to rotate forward or reverse, so that the second connecting screw 32 cooperates with the second transmission screw sleeve 31 to form a screw transmission structure, driving the second sliding block 30 to move horizontally inside the second sliding cavity 29, so that the first connecting frame 33 can move horizontally synchronously, and according to the drilling area, the second movable sleeve 36 is driven to move forward and backward through the screw output transmission structure 35 output, so that the cylinder 38 and the drilling device body 39 correspond to the drilling position. The drilling operation is specifically that the drilling device body 39 outputs and drives the installed drill bit to rotate at a high speed, and then the cylinder 38 outputs the operation to drive the drilling device body 39 vertically downward until it penetrates the drilling area of ​​the circuit board, thereby completing the drilling operation of the circuit board.

[0052] The rear end of the first connecting frame 37 is fixedly connected to a storage chamber 43, and an exhaust net is provided at the bottom end of the storage chamber 43, a top cover 42 is clamped at the top end of the storage chamber 43, the top end of the top cover 42 is connected to one end of the transmission tube 41, and the other end of the transmission tube 41 is plugged into the rear end of the dust collector head 40, the dust collector head 40 corresponds horizontally to the drill bit area of ​​the drilling device body 39, the interior of the storage chamber 43 is vertically movably connected to a dust storage box 44 with a hollow structure, the internal bottom end of the dust storage box 44 is fixedly connected to an air dust filter element 45, and a centrifugal fan is provided inside the storage chamber 43 and below the dust storage box 44.

[0053] By setting up the dust collector head 40, since the dust collector head 40 is horizontally corresponding to the drill bit area of ​​the drilling device body 39, when the drilling device body 39 is reset, the dust impurities attached to the dust collector head 40 are sucked in by centrifugal wind force through the dust collector head 40, so as to prevent the dust impurities from adhering to the drill bit of the drilling device body 39, resulting in a decrease in drilling effect and easy occurrence of line scratches. The dust collector head 40 generates centrifugal force to operate through a centrifugal fan, and then the dust is sucked into the storage cavity 43 through the transmission tube 41 in cooperation with the dust collector head 40, and stored in the dust storage box 44.

[0054] The top of the second connecting frame 34 is fixedly connected to a connecting shell 46 via a fixing frame with a "concave" structure, and metal meshes are provided at both ends of the connecting shell 46. Guide fans 47 are fixedly connected to the inside of the connecting shell 46 at equal intervals.

[0055] By setting up the guide fan 47, during the drilling operation of the circuit board, the dust and the like attached to the surface of the circuit board are processed by the guide fan 47, so that the residual dust is guided from top to bottom by the wind force so as to be stored in the garbage storage box 2, thereby preventing dust and impurities from adhering to the top surface of the circuit board, making it difficult to clean, and causing scratches.

[0056] The first connecting frame 33 is fixedly connected to a second connecting frame 48 near the vertical outer wall of the circuit board drilling operation table 1 , and a silicone stabilizing block 49 with a hollow structure is fixedly connected to the top of the second connecting frame 48 .

[0057] By setting up the silicone stabilizing block 49, during use, the silicone stabilizing block 49 is synchronized with the first connecting frame 33 to be positioned relative to the drilling area of ​​the circuit board. At the same time, the silicone stabilizing block 49 is in contact with the bottom end of the circuit board to be drilled. In this way, through the characteristics of the silicone stabilizing block 49, when the circuit board is drilled, it can effectively provide the required supporting force to avoid the impact caused by drilling, which may cause damage to the circuit board. At the same time, because the silicone stabilizing block 49 has a certain vibration reduction effect, it effectively ensures the stability of the circuit board during the drilling operation.

[0058] The specific use process of this embodiment is as follows:

[0059] First, the circuit board is clamped and fixed, and when the position of the movable plate 4 is adjusted, the output pulley 28 is driven by the motor, so that the output pulley 28 cooperates with the transmission belt 27 to drive the synchronous pulley 26 to rotate, and the first transmission screw sleeves 24 meshed with the outer walls of the first connecting screws 25 on both sides will drive the corresponding movable plate 4 to move through the transmission block 23, so that the movable plate 4 can move relative to or oppositely, so that the size of the circuit board can be quickly adapted, and the first sliding block 6 can move inside the first sliding cavity 5, so as to adjust the positions of the first connecting frame 11 and other components according to the size of the circuit board, and when the first sliding block 6 moves, the outer wall of the first limiting protrusion 8 conflicts with the outer wall of the second limiting protrusion 9 to perform self-limiting;

[0060] Secondly, the abutting roller 13 abuts against the bottom end of the circuit board, and the clamping silicone protrusion 17 is subjected to the potential energy generated by the reset spring 18 and abuts against the top end of the circuit board, thereby completing the rapid clamping and limiting of the circuit board. Moreover, before and after limiting the circuit board, the electromagnetic block 22 can be energized and generate magnetic force, so that the electromagnetic block 22 adsorbs the magnetic block 20, thereby pulling the reset spring 18, so that the first movable sleeve 14 moves vertically upward, thereby driving the clamping silicone protrusion 17 to move upward synchronously, so that a certain gap is left between the bottom end of the clamping silicone protrusion 17 and the top end of the abutting roller 13, so as to facilitate the disassembly and assembly of the circuit board.

[0061] Afterwards, when it is necessary to adjust the position of the first connecting frame 33, the second connecting screw 32 is driven by the motor to rotate forward or reverse, so that the second connecting screw 32 cooperates with the second transmission screw sleeve 31 to form a screw transmission structure, driving the second sliding block 30 to move horizontally inside the second sliding cavity 29, so that the first connecting frame 33 is synchronously moved horizontally, and according to the drilling area, the second movable sleeve 36 is driven to move forward and backward through the screw output transmission structure 35 output, so that the cylinder 38 and the drilling device body 39 correspond to the drilling position. The drilling operation is specifically that the drilling device body 39 outputs and drives the installed drill bit to rotate at a high speed, so that the cylinder 38 outputs the operation again, and drives the drilling device body 39 vertically downward until it penetrates the drilling area of ​​the circuit board, and the drilling operation of the circuit board is completed;

[0062] Finally, when the drilling device body 39 is reset, the dust impurities attached to the dust suction head 40 are sucked by centrifugal wind force through the dust suction head 40 to prevent the dust impurities from adhering to the drill bit of the drilling device body 39, resulting in a decrease in drilling effect and easy to cause circuit scratches. The dust suction head 40 generates centrifugal force to operate through a centrifugal fan, and then sucks the dust into the storage chamber 43 through the transmission tube 41 and the dust suction head 40, and stores it in the dust storage box 44. In this way, the circuit board drilling machine is used.
