Description

Technical Field

[0001] This utility model relates to the field of PCB processing equipment technology, and in particular to a PCB punching device. Background Technology

[0002] PCBs have evolved from single-layer to double-sided, multi-layer, and flexible boards, and are constantly developing towards higher precision, higher density, and higher reliability. They are continuously shrinking in size, reducing costs, and improving performance, ensuring that printed circuit boards will maintain strong vitality in the development of future electronic products.

[0003] PCBs require punching during manufacturing, but current punching equipment only performs positioning punching and does not perform multi-directional punching. This results in the need for manual movement of the PCB during punching, which affects work efficiency. Furthermore, the lack of proper clamping and fixing of the PCB makes it easy to damage the PCB during processing.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] 1. In this utility model, the first motor drives the first lead screw to rotate, and the push sliders on both sides pass through the push rod to clamp the inner pressing plate inward to clamp the PCB. After the PCB is subjected to force on the force plate, the clamping force can be limited by the pressure sensor to avoid excessive inward force on both sides, making the PCB safer when clamped and avoiding damage from force.

[0020] Furthermore, the pressure plate moves downward under the push of the second electric push rod, allowing the second force plate to press the PCB firmly. Under the action of the second pressure sensor, excessive force is prevented, thereby strengthening the pressing state of the PCB, resulting in better pressing effect, stronger stability, and preventing movement during punching, thus improving the punching quality.

[0021] 2. In this utility model, the second motor drives the second lead screw to rotate, which causes the moving slide to move the lower drill bit left and right. When the third motor drives the third lead screw to move the force-bearing slider, the lower drill bit can move back and forth. This enables drilling at different positions on the PCB, avoiding the need to manually adjust the position of the PCB when punching holes at different positions, thus making the work more efficient and the processing faster.

[0022] 3. In this utility model, the filter-type placement plate allows the debris generated during punching to fall into the storage box inside the bottom box, which facilitates the cleaning of debris, making the work more efficient and saving working time. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0032] Please see Figure 1 This utility model provides a PCB punching device, including a horizontally arranged workbench 3 for punching PCBs at the top, making operation more convenient for workers. The bottom end of the workbench 3 is provided with a bottom box 1 that extends through the top, allowing debris to fall into it. However, the top opening is located in the middle, inside the first lead screw 6 and the first positioning rod 118, to prevent debris from entering and being difficult to clean, thus affecting the movement. The bottom box 1 is provided with a removable storage box 2, which facilitates the collection of debris and makes it easy to remove and clean it. The middle of the workbench 3 is provided with a filter-type placement plate 4, which extends through the top of the bottom box 1. This allows debris to fall through the placement plate 4 into the storage box 2 during punching operations, improving the work efficiency and facilitating cleaning.

[0033] Please see Figure 1 , Figure 5 and Figure 6The workbench 3 has side plates 5 on both sides facing upwards, which are used to fix the upper end and set up a moving adjustment mechanism to adjust the punching direction. The upper end of the side plate 5 is equipped with a punching mechanism through the moving adjustment mechanism, which allows it to move back and forth and left and right. The moving adjustment mechanism includes a second lead screw 12 that is horizontally mounted to the top of the side plate 5 through a bearing. A second motor 13 is installed on one side of the side plate 5 and connected to the second lead screw 12. A second positioning rod 120 is installed on the other side of the side plate 5. A movable slide plate 14 is installed between the side plates 5. The movable slide plate 14 has a threaded hole on one side that is connected to the second lead screw 12. The second motor 13 drives the second lead screw 12 to rotate. The movable slide plate 14 can be moved under force to adjust the position of the drill bit 19 at the bottom. A sliding hole on the other side of the movable slide plate 14 connects to the second positioning rod 120, thereby strengthening the support effect of the second positioning rod 120, resulting in better support and stronger stability. A third lead screw 121 is installed in the lower cavity of the movable slide plate 14 via a bearing, and a force-bearing slider 122 is installed inside the lower cavity of the movable slide plate 14. The force-bearing slider 122 has a threaded hole that connects to the third lead screw 121. A third motor 15 is installed on the outside of the movable slide plate 14 and connected to the third lead screw 121. The three motors 15 drive the third lead screw 121 to rotate, which in turn moves the force-bearing slider 122, thereby moving the drill bit 19 at the bottom. This allows for drilling at different positions on the PCB, resulting in higher work efficiency and avoiding the inefficiency caused by manual PCB positioning. It also increases practicality and functionality, leading to better punching quality. The bottom of the force-bearing slider 122 is connected to the punching mechanism for easy movement. The upper end of the moving slide plate 14 has a hanging groove 119, and the top of the force-bearing slider 122 has a hanging plate 16 that slides through the hanging groove 119. The hanging plate 16 increases the force-bearing slider's... The stability of slider 122 prevents it from flipping over when it rotates under force, and the force exerted by slider 122 on third lead screw 121 can be reduced under hanging plate 16, thus reducing wear. The punching mechanism includes a first electric push rod 17 installed at the bottom of slider 122. The first electric push rod 17 can move up and down to punch the PCB, and it is convenient to punch different PCBs. The output end of the first electric push rod 17 is equipped with a fourth motor 18 through the mounting frame. The output end of the fourth motor 18 is connected to a drill bit 19, so that punching can be achieved when the drill bit 19 is driven by the fourth motor 18.

[0034] Please see Figure 1 , Figure 3 and Figure 4The inner ends of the side plate 5 are symmetrically fitted with clamping plates 11 to clamp and limit the PCB placed on both sides when both sides are turned inward. The internal cavity of the worktable 3 is equipped with a pushing mechanism connected to the clamping plates 11 on both sides. One side of the internal cavity of the worktable 3 is connected to a first lead screw 6 with threads mirrored from the center through a bearing, so that when rotated, it can simultaneously drive the pushing sliders 8 on both sides to move inward, so that the PCB is more in the center position for punching when clamped. The outer side of the worktable 3 is equipped with a first motor 7 connected to the first lead screw 6. When the first motor 7 drives the first lead screw 6 to rotate, it is convenient to move and work under force, and clamping is achieved during the movement. The internal cavity of the worktable 3 is provided with a through pushing groove on the outer side of the side plate 5. 9. To facilitate the movement of the push rod 10 under force, the push slider 8 is symmetrically pushed inside the cavity of the worktable 3. One side of the push slider 8 is provided with a threaded hole connected to the first lead screw 6. The upper end of the push slider 8 is connected to the push rod 10, which passes through the side plate 5 and is connected to the clamping plate 11. The push slider 8 moves under the action of the first lead screw 6, so that the push slider 8 can push the clamping plate 11 inward through the push rod 10, thereby achieving the inward clamping operation. The other side of the cavity of the worktable 3 is connected to the first positioning rod 118, and the other side of the push slider 8 is provided with a sliding hole that is slidably connected to the first positioning rod 118. The first positioning rod 118 limits the push slider 8 to prevent the push slider 8 from shaking or shifting during movement, thus making the clamping stability better.

[0035] Please see Figure 2 The clamping plate 11 has a downward-through clamping cavity 110 on its inner side to facilitate clamping of the PCB. A force plate 111 is connected to the inner side of the clamping cavity 110 via a pressure sensor 112. The pressure sensor 112 detects the force on the force plate 111, preventing damage to the PCB due to excessive force on either side. A lower pressure plate 113 is installed at the top of the clamping cavity 110, and a second electric push rod 114 is installed at the top of the clamping plate 11. The output end of the second electric push rod 114 passes through the clamping cavity 110 and the lower pressure plate 113. 4. The downward pushing action of the pressure plate 113 can press the PCB, thereby improving the pressing and fixing effect of the PCB, reducing the displacement during punching, and improving the punching quality. The bottom end of the pressure plate 113 is connected to the force plate 116 through the pressure sensor 115. When the force plate 116 is subjected to force, it can monitor the downward pressure and prevent excessive downward pressure. Telescopic rods 117 are installed on both sides of the pressure plate 11 and connected to the pressure plate 113. The telescopic rods 117 can limit the movement of the pressure plate 11, making the operation more stable.

[0036] Working principle: In use, first connect the first motor 7, second motor 13, third motor 15, first electric push rod 17, fourth motor 18, pressure sensor 112, second electric push rod 114, and pressure sensor 115 to the controller set on the outside, and connect it to an external power supply. Then, place the PCB on the upper end of the placement plate 4. The first motor 7 drives the first lead screw 6 to rotate, causing the push sliders 8 on both sides to push the push rod 10 to move the clamping plate 11 inward, so that the PCB is in the clamping cavity 110 inside the clamping plate 11 and contacts the force plate 111. After the pressure sensor 112 detects the inward pressure, the first motor 7 stops working. The second electric push rod 114 pushes the lower pressure plate 113 downward to press the PCB downward. During punching, the first electric push rod 17 pushes the fourth motor 18 to make the lower drill bit 19 punch downward. The second motor 13 drives the second lead screw 12 to rotate, which can move the sliding plate 14 left and right, so that the lower drill bit 19 can move left and right. The third motor 15 drives the third lead screw 121 to rotate, which can make the force-bearing slider 122 receive force and drive the lower drill bit 19 to move back and forth, thereby realizing the punching work at different positions. The debris generated during punching falls into the storage box 2 through the placement plate 4, thus completing the work.
