Description

Technical Field

[0001] This utility model relates to the field of circuit board processing, and in particular to a circuit board processing punch press. Background Technology

[0002] A circuit board, or printed circuit board, is an indispensable basic component in electronic devices. It is mainly used to support and connect various electronic components, such as resistors, capacitors, transistors, and integrated circuits, and to provide electrical connection paths for these components.

[0003] A circuit board punching machine is a mechanical device specifically used for stamping and forming during the manufacturing process of printed circuit boards. It is mainly used to complete processes such as outline cutting, drilling, punching, and grooving to ensure that the circuit board has the correct dimensions and shape, and to prepare it for subsequent installation of electronic components.

[0004] Currently, most punch presses rely on the limiting rods of the machine base platform to fix the circuit boards when placing them. However, this method is prone to problems such as positional deviation or uneven clamping force, which affects the consistency of the final product quality. Especially when processing large batches or complex multi-layer circuit boards, this error will accumulate and further reduce the yield.

[0005] Therefore, a design is needed to solve the aforementioned technical problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a circuit board processing punching machine.

[0007] The technical implementation scheme of this utility model is as follows: A circuit board processing punch press includes a frame, a collection frame, a cylinder, a stamping plate, a worktable, a pull rod, a pin, a positioning sleeve, and an auxiliary clamping assembly. The frame serves as the mounting carrier for all components. A load-bearing seat is provided on the upper part of the frame. A slot is opened in the middle of the top of the frame. A collection frame is slidably placed in the lower part of the frame. A cylinder with its drive end facing downward is installed on the upper part of the load-bearing seat of the frame. A stamping plate is provided on the piston rod of the cylinder. A worktable is slidably arranged on the top of the frame. A pull rod is provided on one side of the worktable. At least two placement slots are opened on the worktable. Each placement slot can be directly above an empty slot, and the placement slot has a drain for passing waste material. Each corner of the stamping plate is equipped with a pin. Multiple positioning sleeves are set on the outside of the placement slot of the worktable corresponding to the pin positions. When the stamping plate descends, the pins and positioning sleeves engage. The worktable is equipped with an auxiliary clamping assembly for positioning and holding by a circuit board. The auxiliary clamping assembly includes a clamping plate, guide rods and springs. The clamping plate is symmetrically slidably arranged in the placement slot of the worktable. Multiple symmetrical guide rods are set between the outward end of the clamping plate and the worktable. Springs are set between the guide rods and the worktable.

[0008] More preferably, it also includes an automatic transfer unit, which is mounted on both the frame and the worktable.

[0009] More preferably, the automatic pushing assembly includes a mounting base, a motor, gears, and a rack. The mounting base is located in the middle of the load-bearing base of the frame. The motor with its output end facing forward is mounted on the mounting base. A gear is mounted on the output shaft of the motor. A rack with its teeth facing upward is located on the rear side of the top of the worktable. The gear meshes with the rack below it.

[0010] More preferably, the starting end of the worktable is directly opposite the side of the stamping plate, while the placement slot of the worktable is directly opposite the collection box below.

[0011] More preferably, it also includes a handle, with a handle provided on the outside of the collection box, and the handle is provided with a non-slip sleeve.

[0020] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0021] Example: A circuit board processing punching machine, such as Figures 1-5As shown, the assembly includes a frame 1, a collection frame 2, a cylinder 5, a stamping plate 6, a worktable 7, a pull rod 8, a pin 9, a positioning sleeve 10, and an auxiliary clamping assembly. The frame 1 serves as the mounting carrier for all components, supporting all other parts and providing installation and fixing positions. A load-bearing base is provided on the upper part of the frame 1, and a slot is opened in the middle of the top of the frame 1. A collection frame 2 is slidably placed inside the lower part of the frame 1 to collect waste generated during the stamping process, keeping the working area clean. A drive mechanism is installed on the upper part of the load-bearing base of the frame 1. A cylinder 5 with its moving end pointing downwards has a stamping plate 6 mounted on its piston rod, directly stamping the circuit board. The cylinder 5 drives the stamping plate 6 to move up and down, applying a predetermined pressure to complete the stamping operation. A worktable 7 is slidably mounted on the top of the frame 1, with its starting end facing the side of the stamping plate 6. The placement slot of the worktable 7 faces the collection frame 2 below. A pull rod 8 is mounted on one side of the worktable 7 for manual adjustment when special needs arise. The worktable 7 has at least two placement slots. The workbench 7 supports the circuit boards to be processed and provides multiple placement slots for continuous multi-station processing. Each placement slot can be directly above an empty slot, and the placement slots have openings for waste material to pass through. Pins 9 are provided at each corner of the stamping plate 6. Multiple positioning sleeves 10 are provided on the outside of the placement slots of the workbench 7 corresponding to the positions of the pins 9. When the stamping plate 6 descends, the pins 9 engage with the positioning sleeves 10. The positioning sleeves 10 cooperate with the pins 9 to ensure that the stamping plate 6 accurately aligns with the pins each time. The worktable 7 is equipped with an auxiliary clamping assembly for positioning and holding the circuit board in the placement slot. The auxiliary clamping assembly includes a clamping plate 11, a guide rod 12, and a spring 13. The clamping plate 11 is symmetrically slidably arranged in the placement slot of the worktable 7. Multiple symmetrical guide rods 12 are arranged between the outward end of the clamping plate 11 and the worktable 7 to guide and support, so that the clamping plate 11 can slide smoothly. The spring 13 is arranged between the guide rod 12 and the worktable 7 to provide appropriate clamping force and ensure that the circuit board is firmly fixed.

[0022] like Figure 1 and Figure 5 As shown, it also includes an automatic moving assembly, which replaces the pull rod 8 to realize the automatic movement of the worktable 7, thereby improving production efficiency. The automatic moving assembly is mounted on both the frame 1 and the worktable 7. The automatic moving assembly includes a mounting base 14, a motor 15, a gear 16, and a rack 17. The mounting base 14 is located in the middle of the load-bearing seat of the frame 1. The motor 15 with its output end facing forward is mounted on the mounting base 14. The gear 16 is located on the output shaft of the motor 15. A rack 17 with its teeth facing upward is located on the rear side of the top of the worktable 7. The gear 16 meshes with the rack 17 below it. The motor 15 drives the gear 16 to rotate, thereby realizing the meshing of the gear 16 with the rack 17 to drive the worktable 7 to move.

[0023] like Figure 1 and Figure 2As shown, it also includes a handle 3. The outside of the collection box 2 is provided with a handle 3. The handle 3 is provided with an anti-slip sleeve to increase the safety of gripping. The handle 3 makes it convenient for the operator to regularly clean the waste in the collection box 2.

[0024] like Figure 1 and Figure 2 As shown, it also includes an observation window 4. The observation window 4 is embedded in the upper part of the collection box 2. The observation window 4 is made of transparent glass material, which allows the operator to monitor the internal situation in real time without opening the collection box 2, so as to ensure that the processing is carried out smoothly.

[0025] First, the circuit board to be processed is placed in the placement slot on the workbench 7. When the circuit board is placed, it contacts the clamping plate 11, causing it to move inward and be clamped by the spring 13 to ensure that the circuit board is firmly fixed. The motor 15 is started, and the output shaft of the motor 15 rotates, causing the gear 16 to mesh with the rack 17 and drive the workbench 7 to slide along the predetermined track until one of the placement slots is accurately aligned with the position above the empty slot. At this time, the pin 9 under the stamping plate 6 is also aligned with the positioning sleeve 10 on the outside of the placement slot, ready for the next stamping operation. The control cylinder 5 starts to work, and its piston rod drives the stamping plate 6 to move downward. The pins 9 set at each corner of the stamping plate 6 are gradually inserted into the corresponding positioning sleeves 10 during the descent, ensuring that the stamping plate 6 and the placement slot are precisely connected. As the stamping plate 6 continues to descend, it will apply a predetermined pressure to the circuit board in the placement slot to complete the shape punching. The waste generated during the stamping process will fall directly into the collection frame 2 below through the sprue and the empty slot. The circuit board remains on the worktable 7 and is securely fixed by the auxiliary clamping group. After the stamping of one placement slot is completed, the automatic pushing group moves again to move the worktable 7 to the position above the next placement slot, aligning it with the empty slot. Since the worktable 7 has at least two placement slots, it is equivalent to multiple workstations. Therefore, while stamping is being performed at one workstation, circuit boards can be prepared or unloaded at other workstations, greatly improving processing efficiency. All placement slots on the entire worktable 7 pass through the stamping position in sequence to complete their respective processing tasks. The control system can pre-set the processing sequence to ensure that each workstation can be used efficiently and to avoid waiting time. When all placement slots have been stamped, the automatic pushing group moves the worktable 7 back to the starting position. The operator can easily remove the processed circuit board from the worktable 7 and prepare for the next batch of processing. The waste generated during each stamping process will naturally fall into the collection box 2, which is slidably placed in the lower part of the frame 1. The collection box 2 is equipped with a handle 3 on the outside, which makes it easy for the operator to clean the waste regularly and keep the work area clean.
