Description

Technical Field

[0001] The present invention relates to the technical field of punching machines, in particular to a punching machine with a PCB pre-alignment adjustment structure. Background Art

[0002] In traditional PCB punching processes, tool fixation often relies on customized mold designs, resulting in insufficient equipment flexibility. PCBs of varying models, sizes, or hole position requirements often require specific mold structures. Frequent mold changes and adjustments for manufacturers facing small-batch, high-variety orders not only significantly increase production costs but also extend delivery times due to customization cycles. Especially in scenarios requiring high precision, the fixed-position design of existing tool heads makes it difficult to quickly adapt to diverse hole layouts. Repeated mold processing and debugging further exacerbate production costs and time losses. Furthermore, the non-standardized tool head arrangement in traditional punching processes is prone to vibration or offset due to uneven force. Coupled with a lack of rigid support, the dimensional accuracy and relative position tolerance of the holes are difficult to stably control, ultimately leading to cumulative errors in subsequent PCB assembly steps. These issues are particularly prominent in the production of multi-layer boards or high-density interconnect boards, hindering companies' ability to quickly respond to market demands and improve production efficiency. Therefore, a modular punching solution that combines flexibility and high precision is urgently needed to overcome the limitations of existing technologies in small-batch, high-variety production scenarios.

[0003] Patent publication number CN208246938U discloses a PCB punching machine, which belongs to the field of PCB processing equipment and aims to provide a PCB punching machine with high punching quality. The key technical solution is as follows: a PCB punching machine includes a frame and a hydraulic punch mounted on the frame, a work platform is provided directly below the hydraulic punch, a mold corresponding to the hydraulic punch is provided on the work platform, a control box is provided on the outside of the work platform, the mold is clamped and fixed to the work platform by a clamp, a reserved punching hole is vertically opened on the top of the mold, a chip removal port is opened on the bottom of the mold and is vertically connected to the reserved punching hole, and a positioning mechanism for fixing the PCB board is also provided on the top of the mold. This patent is applicable to the field of PCB processing equipment, but there is a problem that the punching mold needs to be customized, which is too costly for small-volume motherboards. Therefore, a PCB pre-alignment adjustment structure punching machine is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a PCB pre-alignment adjustment structure punching machine in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a PCB pre-alignment adjustment structure punching machine, comprising a processing platform, a lifting plate fixedly connected to the top surface of the processing platform, a lifting platform fixedly connected to the rear side of the processing platform, and a punching mechanism provided inside the lifting platform; The cam is fixedly provided with a toothed plate, and the toothed plate ...

[0006] According to the above technical solution, a sliding rod frame is provided above the lifting plate, a material changing and positioning mechanism is provided at the bottom of the lifting plate, a material unloading and collecting mechanism is provided below the material changing and positioning mechanism, and a driving motor is installed on the rear side and the top right side of the lifting platform. The end of the output shaft of the driving motor is fixedly connected to a screw rod, and the outer side of the screw rod is threadedly connected to the upper and lower guide frames, and the side of the guide frame close to the lifting platform is slidably connected to a guide rail.

[0007] According to the above technical solution, the side of the punching template is provided with a groove, and the groove is respectively matched with the slot bar, the clamping bar and the lifting frame, the screw is threadedly connected to the bottom surface of the punching template, and the bottom surface of the positioning plate is provided with a plurality of holes distributed in an equidistant array, the slot rod and the positioning plate are matched with each other, the alignment slot and the slot rod are plug-connected, the punching cutter head slides through the bottom surface from the top surface of the positioning plate, and the lifting frame is fixedly connected to the guide frame located above. When starting to work, the driving motor rotates to drive the connected screw rod to rotate, so that the screw rod drives the guide frame to move downward along the guide rail, and the guide rail movement drives the connected lifting frame downward together, and the matching is adjusted according to the different motherboard models. When matching the punching position, it is necessary to insert multiple tool structures into the corresponding alignment slots on the notching template so that the position of the tool structure corresponds to the punching position of the PCB board, insert the slot rod into the alignment slot, and cover the bottom of the notching template with the positioning plate. Make the punching head pass through the reserved hole on the positioning plate, and fix the four corners of the positioning plate with screws. Then install the notching template on the lifting frame, and rotate the threaded rod to push the slot pushing block to slide along the inclined slot guide plate, and let the inclined slot guide plate push the connection between the clamping bar and the card slot bar to fit the surface of the notching template, and let the clamping bar and the card slot bar fit with the groove on the side of the notching template, so as to achieve rapid fixation of the notching template.

[0008] The top of the lifting plate is fixedly connected to the outer ring of the lifting plate, and the bottom of the lifting plate is fixedly connected to the inner ring of the lifting plate.

[0009] According to the above technical solution, the lifting plate is rotatably connected to the rotating plate frame, a sliding groove for the sliding of the card plate is opened on the outer side of the top end of the outer shaft, the guide groove ring is slidably connected to the inner shaft, and a spiral groove is opened on the outer surface of the inner shaft. The telescopic arc frame, the outer side of the elastic rod is provided with an elastic spring, and the two ends of the elastic spring are respectively fixedly connected to the elastic rod and the telescopic arc frame.

[0010] When the cam is in a state of being rotated by the guide groove of the outer shaft, the cam is pressed against the guide groove of the outer shaft and the guide groove of the outer shaft is pressed against the guide groove of the outer shaft, and the guide groove of the outer shaft is pressed against the guide groove of the outer shaft. The circular ring makes the slot plate slide in the opposite direction along the oblique slot opened on the lifting plate. Due to the damping between the slot plate and the circular ring through the outer shaft, the slot plate pushes the folding rod through the guide groove to squeeze the flexible spring sheet to flip around the fixed block, so that the slot plate passes the folding rod and fits into the block on the hydraulic rod, guiding the slot plate to reset after rotation. At the same time, when the elastic rod is compressed, it pushes the telescopic arc frame to move, so that the telescopic arc frame slides along the thread on the outer side of the inner shaft through the guide groove ring, and the telescopic arc frame is telescoped and inserted into the inside of the outer shaft, so that the rotation of the inner shaft drives the card plate plate and the card plate strip to deflect, so that the card plate strip is deflected out from the side of the turn plate frame, and the main board corners are pushed to fit the inner frame of the turn plate frame to correct the position through the card slot on the side of the card strip. The PCB board is buckled with a corner of the PCB board through the card slot, and the PCB board is pressed against the inner frame of the turn plate frame for positioning, and the put-in PCB board is moved to the processing area by rotation, and the processed PCB board is transferred out by rotation, and the positioning calibration during processing is combined at the same time.

[0011] According to the above technical solution, the material collection mechanism includes a material trough, which is opened on the top surface of the front half of the lifting plate. The inner side of the material trough is hingedly connected to a flip plate, and the bottom surface of the flip plate is fixedly connected to two flipping frames, and a seat plate is slidably connected between the two flipping frames. A lifting plate is provided inside the processing table, and a collection box is fixedly connected to the upper surface of the lifting plate, and a cavity rubber pad is provided inside the collection box.

[0012] According to the above technical solution, the seat plate is fixedly connected to the lifting plate, the screw rod is a bidirectional thread, and the guide frame located below is fixedly connected to the lifting plate. When the screw rod rotates, the guide frame located below drives the lifting plate to rise, and the lifting plate pushes the elastic rod to be compressed, so that the elastic rod is compressed and pushes the telescopic arc frame to retract into the outer shaft. When the card strip contacts the PCB board, the card plate no longer deflects. At this time, the lifting plate continues to apply pressure, and the telescopic arc frame no longer extends into the outer shaft. The telescopic arc frame drives the elastic rod to slide relatively and squeeze the elastic spring. During the rotation of the rotating plate frame, the waste generated by punching will be removed through the lifting and lowering The oblique groove on the surface of the board falls above the lifting plate, and the other part moves along the inclined flip plate with the processed PCB board to the cavity rubber pad above the collection box. The lighter waste will fall above the lifting plate, which can collect the waste and prevent the waste from remaining above the lifting plate and affecting the placement of the bare printed circuit board. When the lifting plate moves down, the lifting plate slides along the flip frame through the connected seat plate, so that the flip frame drives the flip plate to flip and tilt downward, thereby realizing the unloading of the PCB board. The PCB board that falls on the cavity rubber pad will be buffered, and it is convenient for other devices to transfer later.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects: This PCB pre-alignment and adjustment structure punching machine uses a modular slot design to quickly replace or adjust the position and number of the cutter heads. It can adapt to PCB boards of different models, sizes or hole position requirements without the need for customized special molds, greatly reducing the cost and time of production changeovers. It is especially suitable for small-batch, multi-variety production scenarios. Secondly, the equidistant array layout ensures the standardization and consistency of the cutter head positioning. Combined with the rigid support of the mold, it can effectively reduce the offset or vibration during the punching process, ensure the dimensional accuracy and relative position tolerance of the hole position, and avoid PCB assembly problems caused by cumulative errors.

[0014] This PCB pre-alignment adjustment structure punching machine moves the inserted PCB board to the processing area through rotation, and then transfers the processed PCB board out through rotation. At the same time, combined with positioning calibration during processing, it can significantly improve production efficiency and processing accuracy. The rotary transfer mechanism can realize continuous material flow, reduce the idle waiting time in traditional linear transportation, and seamlessly connect the loading and unloading process with the processing, thereby improving overall production efficiency. Positioning calibration during the processing process can ensure the position accuracy of the PCB board in the processing area, avoid positioning deviation caused by cumulative error or mechanical vibration, and ensure the accuracy of processes such as drilling, patch or welding.

[0015] The punching machine with PCB pre-alignment adjustment structure realizes the unloading of PCB boards. The PCB boards that fall on the cavity rubber pad will be cushioned, and it is convenient for subsequent transfer to other devices. The design of using structural rotation to collect stamping waste and guide the unloading of the main board can significantly optimize the production process and improve the overall performance of the equipment. The waste is thrown into a specific collection area through centrifugal force or directional movement, avoiding waste accumulation in the mold or processing area, reducing the frequency of shutdown for cleaning, and reducing the risk of waste scratching the workpiece.

At this time, the grooved plate 69 rotates ninety degrees, and then the hydraulic rod 67 pulls the ring to make the grooved plate 69 slide in the opposite direction along the oblique groove opened on the lifting plate 2. Since there is damping between the grooved plate 69 and the ring through the outer shaft 65, the grooved plate 69 pushes the folding rod 614 through the guide groove 610 to squeeze the flexible spring piece to flip around the fixed block 615, so that the grooved plate 69 passes over the folding rod 614 and fits with the block 68 on the hydraulic rod 67, guiding the grooved plate 69 to reset after rotation.

Combined with positioning calibration during processing, it can significantly improve production efficiency and processing accuracy. The rotary transfer mechanism can achieve continuous material flow, reduce the idle waiting time in traditional linear transportation, and seamlessly connect the loading and unloading process with the processing, thereby improving overall production efficiency. Positioning calibration during the processing process can ensure the position accuracy of the PCB board in the processing area, avoid positioning deviation caused by cumulative error or mechanical vibration, and ensure the accuracy of processes such as drilling, patch or welding. When the screw rod 9 rotates, the guide frame 10 located below drives the lifting plate 72 to rise, and the lifting plate 72 pushes the elastic rod 613 to be compressed. After the elastic rod 613 is compressed, the telescopic arc frame 612 is retracted into the outer shaft 65. When the card strip 63 contacts the PCB board, the card plate 62 no longer deflects. At this time, the lifting plate 72 continues to apply pressure, and the telescopic arc frame 612 no longer extends into the outer shaft 65. The telescopic arc frame 612 drives the elastic rod 613 to slide relatively and squeeze the elastic spring. During the rotation of the rotating plate frame 61, the waste generated by punching will fall above the lifting plate 72 through the oblique groove on the surface of the lifting plate 2. The other part will move to the cavity rubber pad 76 above the collection box 77 along the tilted flip plate 73 with the processed PCB board, and the waste generated with lighter weight will fall The lifting plate 72 can collect waste materials above the lifting plate 72, which can prevent waste materials from remaining above the lifting plate 2 and affecting the placement of the bare printed circuit board. When the lifting plate 72 moves downward, the lifting plate 72 slides along the groove frame 74 through the connected seat plate 75, so that the groove frame 74 drives the flip plate 73 to flip and tilt downward to realize the unloading of the PCB board. The PCB board that falls on the cavity rubber pad 76 will be buffered and convenient for subsequent transfer of other devices. The design of using structural rotation to collect stamping waste and guide the unloading of the main board can significantly optimize the production process and improve the overall performance of the equipment. The waste is thrown into a specific collection area through centrifugal force or directional movement to avoid waste accumulation in the mold or processing area, reduce the frequency of shutdown for cleaning, and reduce the risk of waste scratching the workpiece.
