[0023] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-4As shown, an FPC stamping die for convenient and rapid material unloading includes a base 1, a connecting frame 2 fixedly connected to the surface of the base 1, a lower die base 3 mounted on the surface of the base 1, a hydraulic rod 4 fixedly connected to the inner wall of the connecting frame 2, two limiting rods 5 fixedly connected to the inner wall of the connecting frame 2, an electromagnet 6 slidably connected to the surface of each of the two limiting rods 5, the electromagnet 6 being fixedly connected to the output end of the hydraulic rod 4, an upper die base 7 mounted on the end of each of the two limiting rods 5 away from the connecting frame 2, a stacking device 8 provided on the surface of the base 1, and a cleaning device 9 provided on the surface of the base 1.

[0025] In this embodiment of the utility model: before the stamping operation, the dust and debris generated when the lower die base 3 is placed are cleaned by the cleaning device 9. The circuit board to be stamped is then placed on the surface of the lower die base 3. The hydraulic rod 4 is then activated to drive the upper die base 7 to fit with the lower die base 3, which can achieve the stamping effect. Then the top plate inside the base 1 can push the circuit board out, achieving the effect of rapid unloading. At this time, the operator can activate the stacking device 8 to help the circuit board be taken out from the surface of the lower die base 3 and stacked together.

[0026] like Figures 1-3As shown, the stacking device 8 includes two external rails 801, which are fixedly connected to both sides of the base 1. Slide plates 802 are slidably connected to the surfaces of both external rails 801. A movable frame 803 is slidably connected to the surface of each slide plate 802. Three suction cups 807 are fixedly connected to the lower surface of the movable frame 803. Three cylinders 808 are slidably connected to the upper surface of the movable frame 803. Each of the three cylinders 808 has two circular holes 809 on its arc surface. All three cylinders 808 communicate with the movable frame 803 and the suction cups 807. Two uprights 804 are fixedly connected to the surface of the movable frame 803. A connecting plate 805 is slidably connected to the surface of each upright 804. The lower surface of the connecting plate 805... Three blocking rods 810 are fixedly connected to the base 1, and all three blocking rods 810 are slidably connected to the cylinder 808. A slide rail 811 is fixedly connected to the side wall of the base 1, and a placement plate 812 is slidably connected to the surface of the slide rail 811. A sliding frame 813 is slidably connected to the side wall of the base 1, and a mounting base 814 is fixedly connected to the surface of the sliding frame 813. A double-acting screw 815 is rotatably connected to the surface of the mounting base 814, and two limiting plates 818 are threadedly connected to the surface of the double-acting screw 815. Both limiting plates 818 are slidably connected to the sliding frame 813. The sliding frame 803, in conjunction with the suction cup 807, can adsorb the stamped circuit board. Furthermore, the sliding plate 802 cooperates with the external rail 801 to move the frame 803. 03. The fixed direction of movement allows for easy stacking of multiple circuit boards. Simultaneously, the limiting plate 818, controlled by the bidirectional screw 815, provides a limiting effect, preventing the placed circuit boards from shifting. Springs 806 are fitted onto the surfaces of both uprights 804, with each end of the spring 806 fixedly connected to the moving frame 803 of the connecting plate 805. After the suction cup 807 moves the circuit board to the surface of the placement plate 812, the operator can release their fingers pressing the connecting plate 805. At this time, the spring 806 causes the blocking plate to disengage from the cylinder 808, thus deflating the suction cup 807 and releasing its suction effect, facilitating the transfer of the suction cup 807. Two long plates 81 are slidably connected to the upper surface of the sliding frame 813. 6. Push plates 817 are slidably connected to the sides of the two long plates 816 that are close to each other. Before the stacked circuit boards are transferred, the long plates 816 can slide and cooperate with the push plates 817 to press against the side walls of multiple circuit boards, further adjusting the neatness of the stacked circuit boards. This ensures that the stacked circuit boards are neatly arranged when the placement plate 812 moves outward. Two slide rods 819 are fixedly connected to the side wall of the base 1. Positioning plates 820 are fixedly connected to the surface of the two slide rods 819. The positioning plates 820 are made of elastic metal. When the placement plate 812 is removed, the sliding frame 813 can slide upward, so that the positioning plates 820 can lock and limit the sliding frame 813, which facilitates the removal of the stacked circuit boards.

[0027] In this embodiment of the utility model: after the upper mold base 7 and the lower mold base 3 have completed the stamping of the circuit board, the operator presses the upper mold base 7, causing the sliding frame 813 to disengage from the positioning plate 820 and slide towards the surface of the placement plate 812. At this time, the placement plate 812 is slidably mounted on the base 1 and drives the side wall. The operator then slides the moving frame 803. When the moving frame 803 abuts against the surface of the connecting frame 2, the operator presses the connecting plate 805. At this time, the connecting plate 805 drives the three blocking rods 810 into the interior of the cylinder 808, and the interior of the cylinder 808 is sealed. The operator then presses the moving frame 803, causing the moving frame 803 to drive the suction cup 807 to abut against the surface of the circuit board. At this time, the suction cup 807 adsorbs the circuit board. Then, the operator slides the moving frame 803 away from the base 1, placing the moving frame 803 in a position where... When the circuit board is placed on the surface of plate 812, the connecting plate 805 can be released. At this time, the spring 806 drives the connecting plate 805 to slide upward, causing the blocking rod 810 to disengage from the cylinder 808. As a result, the round hole 809 on the surface of the cylinder 808 produces a venting effect, preventing the suction cup 807 from adsorbing the circuit board, which then falls onto the surface of plate 812. At this time, the operator can adjust the position of the limiting plate 818 according to the size of the circuit board with the bidirectional screw 815. After stacking to a certain height, the operator can slide the long plate 816 and the push plate 817, and with the help of the limiting plate 818, multiple stamped circuit boards can be neatly stacked together. Then, they slide upward towards the sliding frame 813, so that the sliding frame 813 is limited by the positioning plate 820. At this time, the operator can slide the stacked circuit boards out as a whole through the plate 812.

[0028] like Figure 1 and Figure 2 as well as Figure 4As shown, the cleaning device 9 includes a slide 901, which is slidably connected to the upper surface of the base 1. A rotating rod 902 is rotatably connected to the surface of the slide 901, and a mounting rod 903 is slidably connected to the surface of the rotating rod 902. An adhesive sleeve 904 is glued to the surface of the mounting rod 903, and the surface of the adhesive sleeve 904 is coated with an adhesive material. Before the stamping operation, the rotating plate can be rotated and moved to the surface of the lower die base 3 in conjunction with the slide 901. Then, the slide 901 is driven to move back and forth on the lower die base 3. The adhesive sleeve 904 mounted on the surface can achieve adhesive cleaning of the dust inside the upper and lower die base 3, improving the quality of the required stamped circuit board. An auxiliary wheel 905 is rotatably connected to one end of the mounting rod 903 near the slide 901. Material 905 is made of rubber. The auxiliary wheel 905 is slidably connected to the surface of the lower mold base 3, allowing it to contact the surface of the lower mold base 3. The auxiliary wheel 905 increases friction, driving the mounting rod 903 and the adhesive sleeve 904 to rotate. This allows dust to come into contact with areas where no dust has adhered, facilitating the removal of dust. The end of the rotating rod 902 away from the slide block 901 is slidably connected to an insert rod 906, and the end of the insert rod 906 away from the rotating rod 902 is fixedly connected to a tension plate 907. The insert rod 906 is inserted into the rotating rod 902 for installation, and then, with the help of the tension plate 907, it can be secured to the surface of the lower mold base 3. This improves the tightness of contact between the adhesive sleeve 904 and the dust inside the lower mold base 3, further enhancing the adhesion effect.

[0029] In this embodiment of the utility model: before the stamping operation, the rotating rod 902 is rotated so that the mounting rod 903 and the adhesive sleeve 904 (the surface coating can be selected to match the material of the material to prevent waste) are installed on the surface of the rotating rod 902, and the rotating rod 902 is placed flat on the surface of the lower die base 3. At the same time, the operator can insert the insertion rod 906 into the rotating rod 902, and the tension plate 907 is locked on the surface of the lower die base 3. At this time, the operator can move the rotating rod 902 with the help of the tension plate 907, and with the help of the auxiliary wheel 905, the adhesive sleeve 904 can be driven to rotate, thereby cleaning the dust and impurities on the surface of the lower die base 3.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
