Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing, and specifically relates to a punching device for single-sided circuit boards. Background Technology

[0002] A single-sided circuit board is a type of printed circuit board made from single-sided copper-clad board. It serves as a support for electronic components and provides electrical connections for them. Because the components are concentrated on one side and the wires are concentrated on the other side, this type of board is called a single-sided circuit board, also known as a single-sided PCB.

[0003] The general process for single-sided circuit boards involves first cutting the material, then performing photopolymerization, transferring the image via screen printing, cleaning and drying the board, followed by punching with holes of a specified diameter. After punching, the board is cleaned again, then cured, marked, and finally dried to become a qualified product. The punching process requires a punching device to press holes in the board for component insertion. Because the board needs to be continuously pushed forward during punching, the pushing equipment needs additional adjustments to match the punching speed, relying heavily on intelligent sensing and sensor settings, resulting in high pushing costs. This paper proposes an improved single-sided circuit board punching device. Utility Model Content

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, this utility model provides a single-sided circuit board punching device, which has the advantages of automatic advancement with the movement of the punching head and reduced cost.

[0005] To achieve the above objectives, this utility model provides a single-sided circuit board punching device, including a base plate. A carrier, a conveying platform, a pushing platform, and a receiving platform are installed on the upper surface of the base plate. A hydraulic pump is installed on the top of the carrier, and a punching head is slidably provided at the bottom of the hydraulic pump. A connecting plate and a spring are installed on one side of the punching head, and a rocker arm is provided at the other end of the connecting plate. The top of the conveying platform and the receiving platform are both slotted with a sliding groove, and a plate slides in the sliding groove. The top of the pushing platform is provided with an inclined surface.

[0006] The hydraulic pump drives the punch head to rise and fall to press and punch holes in the sheet metal. The rocker arm descends synchronously with the pressing of the punch head and continuously inserts itself through the completed punch holes. The bottom end of the rocker arm rotates as it is inserted, guided by the inclined surface. As the rocker arm rotates, it pushes the sheet metal forward.

[0007] As a further improvement of this utility model, the support member has a vertical part and a horizontal part. The upper end of the horizontal part of the support member supports the hydraulic pump. The hydraulic pump has an output end that passes through the horizontal part of the support member to drive the punching head to move up and down.

[0008] As a further improvement of this utility model, one side of the rocker arm is elastically connected to the spring. When the rocker arm is stationary, it is kept in an inclined state by the pull of the spring. When the rocker arm is stationary and tilted, the bottom horizontal height is higher than the bottom horizontal height of the punch head.

[0009] As a further improvement of this utility model, the connecting plate is rotatably connected to the rocker arm, the inclined surface is inclined and matched with the rocker arm to form a sliding guide at its bottom end, the rocker arm rotates by sliding at its bottom end, and the rocker arm pushes the plate through the side when rotating.

[0010] As a further improvement of this utility model, a spring sheet is installed on one side of the receiving platform, and a locking block is provided at the top of the spring sheet. The upper surface of the locking block is inclined and its horizontal height is adapted to the plate. The locking block is adapted to the diameter of the punched hole on the plate and forms a locking connection.

[0011] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0012] This utility model discloses a single-sided circuit board punching device. When the punching head is driven by a hydraulic pump to lift and lower, it drives the connecting plate and rocker arm on the side of the punching head to lift and lower synchronously. The rocker arm first inserts the already punched hole, and with the sliding guide of the inclined surface, the rocker arm rotates to push the board forward. A locking block is also set to engage with the already punched hole to limit the board, so that the board can only move forward and cannot move backward, thus preventing the board from returning to its original position. Finally, the mechanical structure realizes the function of automatically pushing the board forward with the movement of the punching head, maintaining the synchronization of punching and pushing, improving punching efficiency and reducing equipment costs.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example

[0019] Depend on Figure 1-3 A single-sided circuit board punching device is provided, comprising a base plate 1, a support member 2, a conveying platform 8, a pushing platform 9 and a receiving platform 10 mounted on the upper surface of the base plate 1, a hydraulic pump 3 mounted on the top of the support member 2, a punching head 4 slidably mounted on the bottom of the hydraulic pump 3, a connecting plate 5 and a spring 7 mounted on one side of the punching head 4, and a rocker arm 6 mounted on the other end of the connecting plate 5, the top of the conveying platform 8 and the receiving platform 10 are both slotted with a sliding groove 11, a plate 15 slides in the sliding groove 11, and the top of the pushing platform 9 is provided with an inclined surface 14;

[0020] The hydraulic pump 3 drives the punch head 4 to rise and fall to press and punch the plate 15. The rocker arm 6 descends synchronously with the pressing of the punch head 4 and continues to insert through the completed punch. The bottom end of the rocker arm 6 is guided to rotate by the inclined surface 14 as it is inserted. While the rocker arm 6 is rotating, it pushes the plate 15 forward.

[0021] In this embodiment, when the punching head 4 is driven by the hydraulic pump 3 to perform lifting and lowering operations, it drives the connecting plate 5 and the rocker arm 6 on the side of the punching head 4 to perform lifting and lowering operations simultaneously. The rocker arm 6 first inserts the completed punching hole, and with the sliding guidance of the inclined surface 14, the rocker arm 6 is rotated to push the plate 15 forward. Furthermore, the locking block 13 is set to lock and limit the completed punching hole, so that the plate 15 can only move forward and cannot move backward, thus preventing the plate 15 from returning to its original position.

[0022] Specifically, refer to Figure 1-3 The support member 2 has a vertical part and a horizontal part. The upper end of the horizontal part of the support member 2 supports the hydraulic pump 3. The hydraulic pump 3 has an output end that passes through the horizontal part of the support member 2 to drive the punch head 4 to move up and down.

[0023] In this embodiment, by providing a vertical part and a vertical part on the bearing member 2, the hydraulic pump 3 is supported and its height is maintained. The hydraulic pump 3 provides power support for the lifting and lowering of the punching head 4, so that the punching head 4 can perform stable punching operation on the plate 15.

[0024] Specifically, refer to Figure 1-3 One side of the rocker arm 6 is elastically connected to the spring 7. When the rocker arm 6 is stationary, it is kept tilted by the pull of the spring 7. When the rocker arm 6 is stationary and tilted, the bottom horizontal height is higher than the bottom horizontal height of the punch head 4.

[0025] In this embodiment, a spring 7 is used to maintain the elastic connection between the punch head 4 and the rocker arm 6 and to pull the rocker arm 6 to tilt it, so that it can be synchronously reset when the punch head 4 returns to its original position, so as to facilitate repeated operation. By setting the bottom horizontal height of the rocker arm 6 when it is stationary and tilted to be higher than the bottom horizontal height of the punch head 4, the rocker arm 6 is inserted into the already completed punch first and pulls the plate 15, so that the bottom of the punch head 4 that falls later always faces the part of the plate 15 to be punched.

[0026] Specifically, refer to Figure 1-3 The connecting plate 5 and the rocker arm 6 are rotatably connected. The inclined surface 14 is set at an angle and is matched with the rocker arm 6 to form a sliding guide at its bottom end. The rocker arm 6 rotates by sliding at its bottom end. When the rocker arm 6 rotates, it pushes the plate 15 through its side.

[0027] In this embodiment, by setting a rotating connection between the connecting plate 5 and the rocker arm 6, the bottom end of the rocker arm 6 is guided by the inclined surface 14 and rotates with the connection point of the connecting plate 5 and the rocker arm 6 as the fulcrum. Since the rocker arm 6 is inserted into the punched hole of the plate 15, the plate 15 is synchronously pushed forward by the side when the rocker arm 6 rotates.

[0028] Specifically, refer to Figure 1-3 A spring sheet 12 is installed on one side of the receiving platform 10. A locking block 13 is provided at the top of the spring sheet 12. The upper surface of the locking block 13 is inclined and its horizontal height is adapted to the plate 15. The locking block 13 is adapted to the diameter of the punched hole on the plate 15 and forms a locking connection.

[0029] In this embodiment, by setting a locking block 13 with an inclined upper surface at the top of the spring piece 12, the locking block 13 can be inserted into the completed punch hole of the plate 15 after the plate 15 is pushed in, and then engage with it to limit the plate 15 so that it can only move forward and not backward, so as to prevent the rocker arm 6 from bringing the plate 15 back to its original position when it returns to its original position, thus avoiding repeated operation.

[0030] Working principle:

[0031] This utility model discloses a single-sided circuit board punching device. During use, the operator starts the hydraulic pump 3 to drive the punching head 4 to rise and fall. As the punching head 4 descends, its bottom end punches the board material 15. Simultaneously, the connecting plate 5 and rocker arm 6 on the side of the punching head 4 also descend. Because the rocker arm 6 is at a lower horizontal height, it first inserts into the already punched hole on the board material 15. As the punching head 4 continues to descend, the bottom end of the rocker arm 6 also slides through the punch hole on the inclined surface 14. This sliding guides the rocker arm 6 to rotate around its connection point with the connecting plate 5. Since the rocker arm 6 is inserted into the already punched hole on the board material 15, while rotating under the guidance of the inclined surface 14, the side of the rocker arm 6 also... The plate 15 is pushed forward, causing it to move forward. After the plate 15 moves forward, the part to be punched is moved directly below the punching head 4. At this time, the punching head 4 gradually falls to the blank space of the plate 15 to punch. At the same time, the rotation of the rocker arm 6 causes the completed punching at the front to engage with the locking block 13. At this time, the elasticity of the spring plate 12 and the inclined locking block 13 limit the plate 15. After the punching head 4 completes the punching, it rises back to its original position. The rocker arm 6 also rises and returns to its inclined position under the elastic action of the spring 7. Due to the limitation of the locking block 13, the plate 15 can only move forward and cannot move backward. Therefore, it avoids the situation where the plate 15 is driven back by the rocker arm 6, thus realizing the function of automatic advancement of the plate 15 with the movement of the punching head 4 in the punching device.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
