Description

Technical Field

[0001] The invention belongs to the technical field of circuit board processing, and specifically relates to a circuit board semi-copper hole processing device. Background Art

[0002] In the manufacturing process of electronic products, circuit boards are an indispensable component. Circuit boards are usually composed of a variety of different signal layers and spacer layers. Each layer is connected to each other through half holes. A half hole refers to a hole that is only drilled on one side, and only a certain depth of cutting is made on the other side to achieve conductive connection between different layers. The circuit board half-copper hole processing device is an equipment or process system that can realize the processing of half holes (i.e., only half of a circular hole or a slotted hole) on the circuit board. These holes are usually designed at the edge of the circuit board to facilitate welding or other connection needs.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 9 As shown, the present invention provides a technical solution: a circuit board semi-copper hole processing device, comprising a punching table 1, a carrying plate 2 is arranged above the punching table 1, a fixed slide 3 is fixedly installed on the top of the punching table 1, a telescopic cylinder 5 is fixedly installed on the top of the fixed slide 3, the output end of the telescopic cylinder 5 is fixedly connected to a lifting platform 4, the lifting platform 4 and the fixed slide 3 are slidably connected, two motors 6 are fixedly installed on the top of the lifting platform 4, the output ends of the two motors 6 are fixedly connected to drill bits 7, and the two drill bits 7 are respectively located directly above the edge position of the circuit board, a tension component is arranged on one side of the carrying plate 2, the tension component is used to drive the carrying plate 2 to step forward toward one side, limit components are arranged on both sides of the carrying plate 2, the limit components are used to fix the position of the carrying plate 2 after each forward movement, and a reset component is arranged on the other side of the carrying plate 2.

[0034] During work: the circuit board that needs to be punched is placed above the carrier plate 2. At this time, the two drill bits 7 are just above the first punching point of the circuit board. The telescopic cylinder 5 is started to drive the lifting platform 4 to move downward. When the lifting platform 4 descends, the two drill bits 7 gradually approach the first punching point at the edge of the circuit board, and the motor 6 is started to drive the drill bit 7 to rotate, so as to punch holes at the edge of the circuit board. After the punching work is completed, the telescopic cylinder 5 drives the lifting platform 4 to rise. During the rising process, the carrier plate 2 and the circuit board are moved forward by the tension component. At this time, after the lifting platform 4 rises and resets, the next punching point on both sides of the edge of the circuit board can be just below the two drill bits 7. The telescopic cylinder 5 is used to drive the lifting platform 4 to descend again to perform the punching work. This is repeated until the punching work is completed, and after each forward movement of the carrier plate 2, the limit group The components can fix the position of the carrier plate 2 to avoid vibration during the punching process that may cause the carrier plate 2 to shift or shake, thereby improving the stability of the entire punching process and ensuring the accuracy of the punching points. When the lifting platform 4 rises and resets after the last punching, the reset component can move the carrier plate 2 and the circuit board in the direction of restoration to the initial position, which is convenient for taking out and installing the next circuit board, and also convenient for the next circuit board to be punched. Through the above embodiment, the tension component can make the next punching point on the edge of the circuit board just below the drill bit 7 after each punching, ensuring that each punching point is accurately aligned with the drill bit, thereby reducing the position deviation during punching, simplifying the process of adjusting the position of the circuit board, reducing the operation time, thereby improving the overall production efficiency, and making the punched holes arranged equidistantly, which is conducive to the production and use of circuit boards.

[0035] like Figure 3 to Figure 4 As shown, the tension component includes a clamping seat 8, the inner wall of the clamping seat 8 is rotatably connected to a rope winding shaft 9, the outer wall of the rope winding shaft 9 is wound with a pull rope 10, one end of the pull rope 10 is fixedly connected to one side of the supporting plate 2, a plurality of pulleys 11 are fixedly installed on the bottom of the supporting plate 2, a pulley groove 12 is provided on the inner wall of the top surface of the punching table 1, the pulleys 11 and the pulley grooves 12 are slidably connected, and a rotating component for driving the rope winding shaft 9 to rotate is provided on one side of the rope winding shaft 9.

[0036] During operation: after each drilling is completed, the lifting platform 4 will rotate the rope winding shaft 9 through the rotating component when it rises and resets. Each time the rope winding shaft 9 rotates, the pull rope 10 will be partially wrapped around the outer wall of the rope winding shaft 9, so that the pull rope 10 will pull the supporting plate 2 and the circuit board forward a certain distance when winding, and the next drilling point on the circuit board is just below the drill bit 7. The pulley 11 and the pulley groove 12 can ensure that the supporting plate 2 will not be offset when sliding forward, thereby simplifying the process of adjusting the position of the circuit board and improving the overall production efficiency.

[0037] like Figure 3 to Figure 4 As shown, the rotating assembly includes a clamping seat 15, which is fixedly installed directly above the punching table 1, and one side of the clamping seat 15 is rotatably connected to a ratchet 14, the shaft of the rope winding shaft 9 and the shaft of the ratchet 14 are both fixedly connected to a transmission wheel 20, and a transmission belt 13 is transmission-connected between the outer walls of the two transmission wheels 20, and one side of the clamping seat 15 is provided with a transmission assembly for driving it to rotate.

[0038] During operation: when the lifting platform 4 is ascending and resetting, the ratchet 14 will rotate a certain angle through the transmission component. When the clamping seat 15 rotates, the rope winding shaft 9 will be driven to rotate through the transmission belt 13 and the two transmission wheels 20. Therefore, when the rope winding shaft 9 rotates, it will pull the carrying plate 2 and the circuit board to move forward a certain distance, so that the next punching point is located directly below the drill bit 7, thereby facilitating the next punching work.

[0039] like Figure 6 to Figure 7 As shown, the transmission assembly includes a side connecting plate 16, which is fixedly connected to one side of the lifting platform 4. One side of the side connecting plate 16 is fixedly connected to a hinge seat 17. The shaft rod of the hinge seat 17 is rotatably connected to an embedded rod 18, and one end of the embedded rod 18 is adapted to the shape of a groove between every two oblique teeth of the ratchet 14.

[0040] During operation: when the lifting platform 4 descends to punch holes, the side connecting plate 16 will drive the embedded rod 18 to descend. When descending, one end of the embedded rod 18 will not enter the groove of the helical teeth of the ratchet 14, and will be blocked by the ratchet 14, thereby hingedly rotating with the limit rod 21. At this time, the embedded rod 18 can descend smoothly without causing the ratchet 14 to rotate. When the lifting platform 4 rises and resets, one end of the embedded rod 18 will enter the groove between every two helical teeth. Therefore, the embedded rod 18 will drive the ratchet 14 to rotate when it rises, until the embedded rod 18 rises to a certain extent and breaks away from the contact with the groove, thereby achieving the effect of driving the ratchet 14 to rotate when the lifting platform 4 rises.

[0041] like Figure 6 to Figure 7As shown, an angle spring 19 is fixedly connected to one side of the embedded rod 18, and one end of the angle spring 19 away from the embedded rod 18 is fixedly connected to one side of the side connecting plate 16. The inner wall of the hinge seat 17 is fixedly connected to multiple limit rods 21, and the outer walls of the multiple limit rods 21 are in contact with the outer side of the embedded rod 18.

[0042] During operation: when the embedded rod 18 descends, it will be squeezed by the ratchet 14 and will rotate upward with the shaft of the limit rod 21 as the axis. During the rotation, it will squeeze the angle spring 19 to cause it to deform. When the embedded rod 18 descends to the bottom of the ratchet 14 to perform punching work, the embedded rod 18 will immediately reset under the reaction force of the angle spring 19, and the embedded rod 18 will enter the groove of the ratchet 14 when rising. At this time, due to the limitation of the limit rod 21, the embedded rod 18 will not hinge and rotate downward, thereby achieving the effect of being able to drive the ratchet 14 to rotate when rising.

[0043] like Figures 8 to 9 As shown, the limit assembly includes two connecting blocks 22, and the two connecting blocks 22 are respectively fixedly connected to the two sides of the supporting plate 2, and the bottoms of the two connecting blocks 22 are fixedly connected with a return spring 23, and the bottoms of the return spring 23 are fixedly connected with a trapezoidal block 24, and one side of the two trapezoidal blocks 24 is provided with a limit platform 25, and a plurality of empty slots are provided above the limit platform 25, and the distance between each empty slot is the same as the distance between the hole points of the circuit board.

[0044] During operation: when the supporting plate 2 moves forward in a step-by-step manner, each time during the movement, the bottom of the trapezoidal block 24 will first be restricted by the top of the limit platform 25 and squeeze the reset spring 23 to move upward. After each movement of the supporting plate 2, the trapezoidal block 24 will be immediately reset under the action of the reset spring 23, and will enter the empty slot of the limit platform 25 in turn, so that the trapezoidal block 24 can be inserted into the empty slot without shaking. At this time, when the lifting platform 4 descends to punch holes, the stability of the supporting plate 2 and the circuit board can be maintained, ensuring the accuracy and stability of the punching. When the lifting platform 4 rises, the trapezoidal block 24 will enter the next empty slot again to fix the position of the supporting plate 2 and the circuit board.

[0045] like Figures 8 to 9 As shown, the top of the punching table 1 is symmetrically fixedly connected with sensor 1 26 and sensor 2 27, and the sensor 1 26 and sensor 2 27 are respectively located on both sides of the limit platform 25. An induction magnet 28 is provided on one side of the limit platform 25, and the induction magnet 28 is electrically connected to the sensor 1 26 and the sensor 2 27. The induction magnet 28 is fixedly installed on the top of the punching table 1, and the limit platform 25 is made of ferrous material.

[0046] During operation: after the last punching is completed, the lifting platform 4 will drive the trapezoidal block 24 to continue to move to the farthest end of the limit platform 25 and fit it together. At this time, the trapezoidal block 24 will hit the sensor 26, and the sensor 26 can control the induction magnet 28 to continue to be energized. Since the limit platform 25 is made of ferrous material, the induction magnet 28 will cause the limit platform 25 to be attracted and move closer to the induction magnet 28 after being energized. Therefore, the limit platform 25 is no longer fitted together with the trapezoidal block 24, and the carrier plate 2 and the circuit board will slide backward and reset under the action of the reset component, so that the punched circuit board and the carrier plate 2 return to their initial positions, which is convenient for taking out and installing the next circuit board, and also convenient for the next circuit board to be punched.

[0047] like Figure 2 and Figure 8 As shown, the reset assembly includes a pull rope 32, which is fixedly connected to the other side of the load-bearing plate 2. A fixed pulley 31 is fixedly connected to one side of the load-bearing plate 2. The fixed pulley 31 is slidably connected to the pull rope 32, and a counterweight 33 is fixedly connected to one end of the pull rope 32 away from the load-bearing plate 2.

[0048] During operation: each time the circuit board moves step by step for punching a hole, the counterweight block 33 cannot move or shake the carrier plate 2 due to the restrictions of the trapezoidal block 24 and the limit platform 25. When the last punching point is completed, the induction magnet 28 is energized to move the limit platform 25 toward it. At this time, under the action of the counterweight block 33, the carrier plate 2 will be subjected to a pulling force toward one side of the counterweight block 33, causing the carrier plate 2 to slide in the opposite direction and directly return to its initial position.

[0049] like Figures 8 to 9 As shown, the inner walls at both ends of the limit platform 25 are slidably connected with a slide rod 30, one end of the slide rod 30 is fixedly connected to one side of the punching platform 1, and the outer wall of the slide rod 30 is provided with a return spring 29, and the two ends of the return spring 29 are respectively fixedly connected to one side of the limit platform 25 and one side of the punching platform 1.

[0050] During operation: when the trapezoidal block 24 moves to the initial position, one side of the trapezoidal block 24 will hit one side of the sensor 27, and the sensor 27 will control the induction magnet 28 to cut off the power. After the power is cut off, the induction magnet 28 no longer generates suction. At this time, the limit table 25 will return to the initial position under the action of the slide bar 30. When the next circuit board punching is performed, the trapezoidal block 24 can enter the empty slot of the limit table 25 again in turn to fix the position of the carrier plate 2. This operation is repeated to complete the entire punching production process.

[0051] like Figure 5As shown, a pressing piece 34 is provided under the lifting platform 4, and a plurality of plug-in rods 36 are fixedly connected to the top of the pressing piece 34. The plug-in rods 36 are slidably connected to the inner wall of the lifting platform 4, and the outer walls of the plurality of plug-in rods 36 are provided with return springs 35. The two ends of the return springs 35 are respectively fixedly connected to the top of the pressing piece 34 and the bottom of the lifting platform 4.

[0052] During operation: when the lifting platform 4 descends and the drill bit 7 gradually approaches the edge position of the circuit board, the pressing member 34 will contact the circuit board above the carrier plate 2 in advance. At this time, the pressing member 34 will clamp and fix the circuit board in the position above the carrier plate 2, and when the drill bit 7 descends during drilling, the pressing member 34 will squeeze the return spring 35 to deform it, so that during the entire drilling process, the pressing member 34 can press down the circuit board to fix it above the carrier plate 2, thereby avoiding the shaking of the circuit board above the carrier plate 2 due to vibration during the drilling process.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
