Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of machinery and relates to an anti-drop structure for a punching machine, in particular to an anti-drop structure for a stamping production die of a printed circuit board. Background Art
[0002] Printed circuit boards (PCBs) are usually produced by punching and contour processing using stamping dies. Punching can be used to process simple PCBs and is suitable for large-scale PCB production. The key to stamping dies for PCB processing is the design and processing of the dies, as well as the installation and commissioning of the dies. Usually one or several dies are used for stamping work at different stages.
[0003] The existing stamping mold is simply designed and has no protective structure for the processed product. After the PCB board is stamped, it falls directly from the mold outlet, which can easily cause damage to the corners of the PCB board and scratches on the surface. In addition, it is easy for the PCB boards to collide with each other, further causing damage to the surface of the PCB board and deepening the degree of damage, thereby resulting in poor quality of the finished PCB board.
[0004] In summary, in order to solve the deficiencies in the structure of the existing PCB board stamping die, the utility model designs an anti-drop structure for a punch press with a reasonable structure and good use effect. Summary of the invention
[0005] The utility model solves the problems existing in the prior art and provides an anti-drop structure for a punch press which has a reasonable structure and good use effect.
[0006] The purpose of the utility model can be achieved through the following technical solutions: A punching machine anti-drop structure, comprising:
[0007] A base, the bottom of which is provided with a collection frame;
[0008] The lower template is located above the base, and is provided with a plurality of outlets for outputting PCB boards. At least one transition plate is provided at the outlet, and the transition plate extends obliquely to the collecting frame;
[0009] The upper template is buckled on the lower template. When the upper template moves toward the lower template and performs stamping, the obtained PCB board moves smoothly along the transition plate to the aggregate frame.
[0010] As a further improvement of the present case, both sides of the transition plate are bent and extended upward to form ribs, and the inner side of each rib is covered with an elastic layer, and the elastic layer has a smooth surface.
[0011] As a further improvement of the present invention, the bottom of the transition plate smoothly transitions to the aggregate frame, and a sponge pad is laid in the aggregate frame.
[0012] As a further improvement of the present invention, the transition plate is arranged in a curved slideway.
[0013] As a further improvement of the present case, two transition plates are provided, namely an upper plate and a lower plate. The arc surface of the upper plate transitions to the lower plate, and the bottom portion of the lower plate extends out of the base.
[0014] Compared with the prior art, the utility model has a reasonable structural arrangement. The smooth discharge of the PCB board is achieved through the arrangement of the transition plate. The arrangement of the retaining edge can avoid damage to the PCB board, which is beneficial to improving product quality. At the same time, the transition plate is smoothly connected with the collection frame to avoid collision between the PCB board and other PCB boards when the PCB board reaches the collection frame, thereby further ensuring the finished product quality of the PCB board.

[0021] The technical solution of the utility model is further described below in conjunction with the embodiments and drawings.
[0022] like Figure 1 and Figure 2 As shown, the anti-drop structure for the punch press includes:
[0023] A base 10, a material collecting frame 11 is arranged at the bottom thereof;
[0024] The lower template 22 is located above the base 10. The lower template 22 is provided with a plurality of outlets 23 for outputting PCB boards. At least one transition plate 30 is provided at the outlet 23. The transition plate 30 extends obliquely to the collection frame 11.
[0025] The upper template 21 is buckled on the lower template 22. When the upper template 21 moves toward the lower template 22 and performs stamping, the obtained PCB board moves smoothly along the transition plate 30 to the collection frame 11.
[0026] The existing stamping die is simply designed and has no protective structure for the processed product. After the PCB board is stamped, it falls directly from the die outlet 23, which easily causes damage to the corners of the PCB board and scratches on the amber surface. In addition, it is easy for the PCB boards to collide with each other, further causing damage to the surface of the PCB board and deepening the degree of damage, thereby resulting in poor quality of the finished PCB board.
[0027] To this end, the utility model provides an anti-drop structure for a punch press, which realizes the smooth discharge of PCB boards through the setting of the transition plate 30, avoids the PCB boards from falling and collision damage, etc., which is beneficial to improving product quality and ensuring the finished product quality of the PCB boards.
[0028] Specifically, the bottom of the stamping die base 10 is hollowed out to facilitate the unloading of stamping products. In this embodiment, a transition plate 30 is preferably provided below the stamping outlet 23 to facilitate the PCB board to slide smoothly along the transition plate 30 to the corresponding collection frame 11.
[0029] Preferably, both sides of the transition plate 30 are bent upward and extended to form retaining edges 31, and the inner side of each retaining edge 31 is covered with an elastic layer 32, and the elastic layer 32 has a smooth surface. The setting of the retaining edges 31 here can limit the movement of the PCB board along the transition plate 30 when it slides, and prevent the PCB board from sliding out of the transition plate 30 and falling directly on the ground, causing damage to the product.
[0030] An elastic layer 32 is arranged on the inner side of the retaining edge 31. When the PCB board collides with the retaining edge 31, a certain buffering force is applied to reduce damage to the PCB board. At the same time, the elastic layer 32 is preferably a smooth surface to facilitate the sliding of the PCB board, avoid the PCB board from being hooked with the retaining edge 31, and ensure that the PCB board can smoothly fall along the transition plate 30 to the collection frame 11 in time.
[0031] Furthermore, the bottom of the transition plate 30 smoothly transitions to the material collection frame 11, and a sponge pad 12 is laid in the material collection frame 11. Preferably, a smooth section 333 is provided at the bottom of the transition plate 30 to facilitate the PCB board to smoothly slide to the material collection frame 11 when it reaches the bottom, further ensuring that the PCB board slides smoothly.
[0032] In addition, a sponge pad 12 is preferably provided in the collection frame 11 to reduce vibration when the PCB board slides into the collection frame 11, thereby reducing collision and damage, and facilitating the collection of more PCB boards.
[0033] Preferably, if Figure 3As shown in the structural diagram of the second embodiment of the utility model, the transition plate 30 is arranged in a curved slide. In actual production, the transition plate 30 can adopt a curved slide structure to facilitate the PCB board to slide down along the slide during the sliding process, ensuring that the PCB board slides smoothly.
[0034] Furthermore, if Figure 4 and Figure 5 As shown, it is a schematic structural diagram of the third embodiment of the utility model, the transition plate 30 is provided with two, namely an upper plate 331 and a lower plate 332 , the upper plate 331 transitions to the lower plate 332 through an arc surface, and the bottom portion of the lower plate 332 extends out of the base 10 .
[0035] It is worth mentioning that the transition plate 30 can be provided with a plurality of transition plates 30 connected according to the height of the actual outlet 23 from the ground, so as to reduce the overall tilt angle and facilitate the smooth sliding of the PCB board. The actual number of the transition plates 30 is not limited in the present invention. The transition plate 30 and the collection frame 11 can still use a smooth section 333 for transition to ensure that the PCB board smoothly falls into the collection frame 11.
[0036] Preferably, the bottom portion of the lower plate 332 extends out of the base 10, which is convenient for reducing the inclination of the transition plate 30 on the one hand, and is convenient for the operator to directly collect the stamped PCB board outside the mold on the other hand.
[0037] The anti-drop structure of the punch press is reasonably arranged. The smooth discharge of the PCB board is achieved through the arrangement of the transition plate 30. The arrangement of the retaining edge 31 can avoid damage to the PCB board, which is beneficial to improving product quality. At the same time, the transition plate 30 is smoothly connected with the collection frame 11 to avoid collision between the PCB board and other PCB boards when the PCB board reaches the collection frame 11, thereby further ensuring the finished product quality of the PCB board.
[0038] The preferred embodiments of the present invention are described herein, but the protection scope of the present invention is not limited thereto. Any modification or supplement or replacement of the specific embodiments described by technicians in the field of the present invention shall be included in the protection scope of the present invention.
