[0002] PCB stands for Printed Circuit Board, also known as Printed Circuit Board. It is an important electronic component, serving as the support for electronic components and the carrier for electrical connections between them. Because it is made using electronic printing technology, it is called a "printed" circuit board. During the processing of printed circuit boards, stamping dies are used to stamp the circuit boards.

[0003] However, existing stamping dies are not suitable for quickly punching the edges of printed circuit boards, nor are they suitable for quick die replacement, resulting in low practicality and hindering long-term use and promotion.

[0004] To address these issues, those skilled in the art have provided a novel flexible printed circuit board stamping die. Utility Model Content

[0005] The purpose of this invention is to provide a novel flexible printed circuit board stamping die that can solve the problems mentioned in the background art.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A novel flexible printed circuit board stamping die includes a base, a support plate fixed to the rear end of the outer top surface of the base, a top plate fixed to the outer top surface of the support plate, a lower die fixed to the front end of the outer top surface of the base by bolts, an upper die provided on the outer bottom surface of the top plate, and a stamping assembly provided on the outer top surface of the top plate.

[0008] The stamping assembly includes a square cover fixed to the outer top surface of the top plate. A rotating shaft is rotatably installed inside the square cover. The two ends of the rotating shaft extend rotatably to the left and right outer walls of the square cover, and connecting blocks are fixed to the outer peripheral walls of both connecting blocks. Round rods are fixed to the opposite outer outer walls of the two connecting blocks. Connecting plates are rotatably sleeved on the outer peripheral walls of the two round rods. A connecting seat is provided on the outer top surface of the base. Round rods are fixed to the outer walls of the left and right sides of the connecting seat. The ends of the two connecting plates near the connecting seat are rotatably sleeved on the outer peripheral walls of the two round rods.

[0009] The present invention is further configured such that: a U-shaped sleeve is fixed on the outer bottom surface of the connecting seat, and a horizontal block is fixed on the outer top surface of the upper mold; the horizontal block is snapped into the inner side of the U-shaped sleeve and fixed to each other by bolts threaded together.

[0010] The present invention is further configured such that: a worm gear is fixed inside the square cover and on the outer peripheral side wall of the rotating shaft; a worm is rotatably installed inside the square cover and on the outer top surface of the top plate; the worm gear and the worm are meshed; a drive motor is fixed on the outer top surface of the square cover; and one end of the worm extends rotatably to the outer top surface of the square cover and is fixedly connected to the output end of the drive motor.

[0011] The present invention is further configured such that: a support rod is symmetrically fixed between the base and the top plate; a connecting sleeve is fixed at both the upper and lower ends of the outer peripheral sidewalls of the two support rods; a sliding plate is fixed to the front outer wall of the two connecting sleeves; a sliding sleeve is slidably connected to the front outer wall of the sliding plate; and the front outer wall of the sliding sleeve is fixedly connected to the rear outer wall of the connecting seat.

[0012] The present invention is further configured such that: a square slice is fixed on the outer bottom surface of the upper mold, and a groove matching the square slice is opened on the outer top surface of the lower mold.

[0013] The present invention is further configured such that: a spiral plate is fixedly sleeved on the bottom of the outer side wall of the base, and the spiral plate has through screw holes at the four corners of its outer top surface.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This utility model discloses a novel flexible printed circuit board stamping die. It uses a drive motor as a power source and, with the assistance of a worm gear and worm, drives a rotating shaft to rotate through a connecting block, thereby driving the connecting seat to move the upper die downward. This, in conjunction with the lower die, rapidly punches the edge of the circuit board, thus improving its practicality and facilitating long-term use and promotion.

[0027] 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.

[0028] like Figure 1-4 As shown, a novel flexible printed circuit board stamping die includes a base 1. A U-shaped plate 105 is fixedly sleeved on the bottom of the outer side wall of the base 1. Each of the four corners of the outer top surface of the U-shaped plate 105 has through-hole screw holes. Tightening the bolts in the screw holes can fix the U-shaped plate 105 in the working area, thereby ensuring the stability of the base 1 during the stamping process. A support plate 101 is fixed to the rear end of the outer top surface of the base 1, and a top plate 102 is fixed to the outer top surface of the support plate 101. The front end of the outer top surface of the base 1 is connected by bolts. A lower mold 103 is fixed, and an upper mold 104 is provided on the outer bottom surface of the top plate 102. A U-shaped sleeve 3 is fixed on the outer bottom surface of the connecting seat 206, and a horizontal block 301 is fixed on the outer top surface of the upper mold 104. The horizontal block 301 is snapped into the inner side of the U-shaped sleeve 3 and fixed to each other by bolt threads. Inserting the horizontal block 301 into the inside of the U-shaped sleeve 3 facilitates subsequent separation. At the same time, the use of bolt thread connection facilitates the replacement of the upper mold 104 and the lower mold 103 in the later stage, thereby increasing the flexibility of use.

[0029] A stamping assembly 2 is provided on the outer top surface of the top plate 102. The stamping assembly 2 includes a square cover 201 fixed to the outer top surface of the top plate 102. A rotating shaft 202 is rotatably mounted inside the square cover 201. The two ends of the rotating shaft 202 extend rotatably to the left and right outer walls of the square cover 201, respectively. Connecting blocks 203 are fixed to the outer peripheral walls of the two connecting blocks 203. Round rods 204 are fixed to the opposite outer outer walls of the two round rods 204. Connecting plates 205 are rotatably sleeved on the outer peripheral walls of the two round rods 204. A connecting seat 206 is provided on the outer top surface of the base 1. Round rods 207 are fixed to the outer walls of both sides of the connecting seat 206. Two connecting plates 205 are rotatably sleeved on the outer peripheral walls of the two round rods 207 near the connecting seat 206. A worm gear 208 is fixed inside the square cover 201 and on the outer peripheral wall of the rotating shaft 202. A worm 209 is rotatably installed inside the square cover 201 and on the outer top surface of the top plate 102. The worm gear 208 and the worm 209 are meshed. A drive motor 210 is fixed on the outer top surface of the square cover 201. One end of the worm 209 extends rotatably. The top surface of the square cover 201 is fixedly connected to the output end of the drive motor 210. Support rods 4 are symmetrically fixed between the base 1 and the top plate 102. Connecting sleeves 401 are fixed to the upper and lower ends of the outer periphery of the two support rods 4. A sliding plate 402 is fixed to the front outer wall of the two connecting sleeves 401. A sliding sleeve 403 is slidably connected to the front outer wall of the sliding plate 402. The front outer wall of the sliding sleeve 403 is fixedly connected to the rear outer wall of the connecting seat 206 (the sliding sleeve 403 moves up and down along the outer wall of the sliding plate 402, thus ensuring the connection...). (Stability of the vertical movement of the connector 206) In use, the drive motor 210 is controlled and started to drive the worm gear 209 to drive the worm wheel 208 to rotate, thereby driving the rotating shaft 202 to drive the connecting block 203 to perform circular motion, thereby driving the connecting plate 205 to drive the connector 206 to move up and down along the slide plate 402, so that the upper mold 104 moves back and forth towards the lower mold 103, and works with the lower mold 103 to quickly punch the edge of the circuit board, thereby improving practicality and being conducive to long-term use and promotion.

[0030] A square slice 5 is fixed on the outer bottom surface of the upper mold 104, and a cutting groove 501 that matches the square slice 5 is opened on the outer top surface of the lower mold 103. The square slice 5 is driven back and forth to the inside of the cutting groove 501 by the upper mold 104, thereby achieving the punching effect.

[0031] The working principle of this utility model is as follows: When in use, the printed circuit board is first accurately transported and positioned on the outer top surface of the lower mold 103 by an external conveying and positioning device (the conveying and positioning device is a conventional technical device in this field, which can continuously and stably transport a large board composed of multiple printed circuit boards to the lower mold 103 in sequence; its working principle and structural features will not be specifically described and shown in this article).

[0032] At the same time, the start-up drive motor 210 drives the worm gear 209 to drive the worm wheel 208 to rotate, thereby driving the rotating shaft 202 to drive the connecting block 203 to perform circumferential motion, so that the connecting plate 205 drives the connecting seat 206 to move up and down along the slide plate 402, so that the upper mold 104 drives the square slice 5 to move back and forth to the inside of the cutting groove 501 of the lower mold 103, so as to quickly punch the edge of the circuit board.

[0033] At the same time, turning the bolts allows for quick disassembly and replacement of the upper mold 104 and the lower mold 103.

[0034] It should be noted that all electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art, so the control method and circuit connection will not be explained in detail.

[0035] 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 shall be implemented according to conventional methods in the art unless otherwise specified or limited.
