Description

Technical Field

[0001] This utility model relates to the field of PIN technology, and specifically to a PIN hole opening device. Background Technology

[0002] A pin, also called a lead, is a wire that connects the internal circuitry of an integrated circuit (chip) to the external circuitry. All the pins together form the interface of the chip. The end of the lead is soldered to the pads on the printed circuit board to form a solder joint. Pins can be divided into heels, toes, sides, etc.

[0003] A search revealed publication number "CN219352018U" discloses "a PIN pressing machine, which aims to provide a device that first positions the insert pin with limiting pins, and then applies pressure from a pressure plate to fully align and press the insert pin with the PIN pin housing. The key technical points include a frame, a sieve plate on the frame, a pressure plate positioned above and parallel to the sieve plate, and a drive device for moving the pressure plate up and down. The sieve plate has several evenly distributed sieve holes, and a PIN pin housing with a top opening is inserted into each sieve hole. The PIN pin housing contains an insert pin, the top of which has a downward-facing recessed hole. The upper surface of the insert pin protrudes from the upper surface of the PIN pin housing. The lower surface of the pressure plate has several limiting pins with the same shape as the recessed hole. This device first positions the insert pin and then presses it with the PIN pin housing, reducing product scrap rate and thus improving production efficiency."

[0004] While the aforementioned device can reduce product scrap rate by first positioning the ferrule and then pressing the pins together, it cannot quickly and automatically remove the finished circuit board and pins after drilling holes in the pins on the circuit board. It still requires manual handling, which is not only time-consuming and laborious, but also poses certain safety hazards during the handling process, which is extremely detrimental to the safe production of the device.

[0011] Furthermore, the upper end of the movable plate is provided with multiple vertical holes, and the movable plate is slidably connected to the circumferential surface of multiple support rods through the multiple vertical holes.

[0012] Furthermore, two sets of positioning mechanisms are provided on the lower side of the pressing plate.

[0032] In a specific embodiment of this utility model, when it is necessary to drill holes in the PIN pins of the circuit board, the circuit board is placed inside the mounting housing 11, and then the lead screw 3 is rotated to move the lead screw nut 2 connected to its circumferential surface, and simultaneously drive the pressing plate 1 and multiple drilling rods 16 to descend, drilling the required PIN pin holes in the circuit board. After drilling is completed, the lead screw 3 rotates in the opposite direction to drive the lead screw nut 2 to move upward, and then simultaneously drive the vertical plate 6, the driving rod 9 and the moving plate 15 to move upward. Then, multiple ejector rods 12 will move upward simultaneously and push the circuit board inside the mounting housing 11 upward through the positioning holes, making it easier to pick up the circuit board. Through the above design, drilling the PIN pin holes in the circuit board is simpler and picking them up is more convenient and faster. When the pressing plate 1 moves, it will simultaneously drive the vertical plate 6 to slide on the circumferential surface of the vertical rod 7, improving the vertical movement stability of the pressing plate 1.

[0033] Please refer to the details. Figure 1-5 Two connecting blocks 14 are fixedly connected to both ends of the mounting shell 11. Support rods 13 are fixedly connected to the lower ends of the multiple connecting blocks 14. Multiple vertical holes are opened at the upper end of the movable plate 15, and the movable plate 15 is slidably connected to the circumferential surface of the multiple support rods 13 through the multiple vertical holes.

[0034] In this embodiment, the mounting shell 11 and multiple components can be supported by multiple connecting blocks 14 and multiple support rods 13. When the moving plate 15 moves, it can slide on the circumferential surface of the support rod 13 through the vertical hole, thereby improving the vertical movement stability of the moving plate 15.

[0035] Please refer to the details. Figure 1-5 Two sets of positioning mechanisms are provided on the lower side of the pressing plate 1. Each set of positioning mechanisms consists of a thick rod 17, a placement groove 23, a spring 22, a thin insertion rod 20, and a lower pressure plate 19. The thick rod 17 is fixedly connected to the lower end of the pressing plate 1. The placement groove 23 is opened at the lower end of the thick rod 17.

The lower pressure plate 19 is fixedly connected to the lower end of the thin insertion rod 20.

[0036] In this embodiment: when the pressing plate 1 moves downward, the lower pressing plate 19 will abut against the punched circuit board, making the circuit board stable and facilitating subsequent punching. Through the elastic function of the spring 22, the lower pressing plate 19 can adapt to circuit boards of different thicknesses.

[0037] Please refer to the details. Figure 1-5A telescopic rod 24 is fixedly connected to the upper inner wall of spring 22. Spring 22 is sleeved on the circumferential surface of telescopic rod 24.

The output end of motor 5 is fixedly connected to lead screw 3. A limiting plate 8 is fixedly connected to the upper end of vertical rod 7.

[0038] In this embodiment: the telescopic rod 24 can prevent the spring 22 from bending and deforming, thus preventing damage. When the thin insertion rod 20 moves, it can drive the limiting block 21 to slide in the limiting groove 18, thereby improving the vertical movement stability of the thin insertion rod 20. The motor 5 can automatically drive the lead screw 3 to rotate. The limiting plate 8 can prevent the vertical plate 6 from moving excessively, thus preventing damage.

[0039] Working principle: When it is necessary to drill holes in the PIN pins of the circuit board, the circuit board is placed in the mounting housing 11, and then the lead screw 3 is rotated to move the lead screw nut 2 connected to its circumferential surface. At the same time, the pressing plate 1 and multiple drilling rods 16 are driven down to drill the required PIN pin holes in the circuit board. After the drilling is completed, the lead screw 3 rotates in the opposite direction to drive the lead screw nut 2 to move upward. Then, the vertical plate 6, the driving rod 9 and the moving plate 15 are driven up simultaneously. Then, multiple ejector rods 12 move up simultaneously and push the circuit board in the mounting housing 11 upward through the positioning holes, making it easier to pick up the circuit board. Through the above design, the drilling of PIN pin holes in the circuit board is simpler and the picking up is more convenient and faster. When the pressing plate 1 moves, it will drive the vertical plate 6 to slide on the circumferential surface of the vertical rod 7, improving the vertical movement stability of the pressing plate 1.
