Abstract
Description
Technical Field
[0001] This utility model belongs to the field of PIN stripping machine technology, specifically relating to a PIN stripping mechanism and a PIN stripping machine. Background Technology
[0002] PIN-Lam production boards are made by hot-pressing multiple layers of copper foil. During the pressing process, pins are usually used to position the layers to improve the quality of the finished circuit board. After pressing, the pins need to be removed. The traditional method is to set a pin removal board on the base plate, and a servo cylinder is mounted on the base plate. The output end of the servo cylinder is connected to the pin removal board. The pin removal board is separated from the base plate by lifting it. That is, the pins are removed by the movement of the pin removal board without moving the pins. Since there are multiple pins positioned on the pin removal board, multiple servo cylinders need to move synchronously when lifting the pin removal board. If they do not move synchronously, it may cause pin jamming or pin breakage. Utility Model Content
[0003] The purpose of this invention is to overcome the defects in the prior art where multiple servo cylinders need to operate synchronously when lifting the PIN removal board. If there is no synchronous operation, it may lead to pin jamming or pin breakage. This invention provides a PIN removal mechanism and a PIN removal machine.

[0023] 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 merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] like Figures 1 to 4 As shown, this application embodiment provides a PIN removal mechanism 10. The PIN removal mechanism 10 is installed at the bottom of the base plate 20, and the top of the base plate 20 is used to place the board material, which is a PCB board. Taking the PCB board as an example, a positioning hole is provided on the PCB board, and a PIN hole 21 is provided on the base plate 20. The PIN removal mechanism 10 includes a driving member 11, a connecting seat 12, and a PIN pin 13. During the pressing process of the PCB board, the driving member 11 drives the connecting seat 12 and the PIN pin 13 to move, so that the PIN pin can pass through the PIN hole 21 and the positioning hole in sequence to achieve the positioning of the PCB board.
[0025] The driving component 11 is mounted on the base plate 20. The connecting seat 12 is connected to the output end of the driving component 11. The output end of the driving component 11 moves synchronously to drive the connecting seat 12. A PIN pin 13 is mounted on the connecting seat 12. When the PIN release mechanism 10 is installed, the PIN pin 13 is positioned directly below the PIN hole 21. The output end of the driving component 11 can extend and retract in the vertical direction, thereby causing the PIN pin 13 to disengage from or enter the PIN hole 21. Specifically, when the output end of the driving component 11 extends, the PIN pin 13 disengages from the PIN hole 21; when the output end of the driving component 11 retracts, the PIN pin 13 can enter the PIN hole 21.
[0026] By placing the PIN pin 13 on the connector 12, which is connected to the output of the driver 11, the driver 11 moves the single PIN pin 13. Compared to the method where multiple drivers 11 move synchronously to move the PIN release board, this solution allows a single driver 11 to move a single PIN pin 13, eliminating concerns about pin jamming. Furthermore, the reduction of the PIN release board results in a simpler overall structure and lower cost.
[0027] In this application, the driving component 11 is installed at the bottom of the base plate 20. The output end of the driving component 11 extends vertically downward. When the output end of the driving component 11 extends, the PIN pin 13 disengages from the PIN hole 21. When the output end of the driving component 11 retracts upward, the PIN pin 13 can enter the PIN hole 21 under the drive of the driving component 11, thereby positioning the PCB board.
[0028] In one embodiment, the connector 12 includes a first connecting segment 121 connected to the drive member 11 and a second connecting segment 122 connected to the PIN pin. The first connecting segment 121 and the second connecting segment 122 are integrally formed, and the connection between the first connecting segment 121 and the second connecting segment 122 is L-shaped. The connection between the first connecting segment 121 and the second connecting segment 122 is thickened and has a curved transition, which gives the connector 12 sufficient strength and a longer service life.
[0029] Specifically, the top end of the second connecting segment 122 is provided with a pin hole, and the PIN pin 13 is inserted and fixed in the pin hole. During installation, the top surface of the second connecting segment 122 is parallel to the base plate 20, and the PIN pin 13 is perpendicular to the top end of the second connecting segment 122. In this way, when the driving component 11 drives the PIN pin 13 to move, the PIN pin 13 can make reciprocating linear motion in the same direction, thereby avoiding collision with the inner wall of the PIN hole 21 of the base plate 20 and causing the pin to jam.
[0030] In this application, the PIN removal mechanism 10 also includes a mounting base 14, and a driving component 11 is disposed on the mounting base 14. Specifically, the driving component 11 is a servo cylinder. The mounting base 14 is disposed at the bottom of the base plate 20 for fixing the servo cylinder. The mounting base 14 is also provided with a guide seat 15, which is located on one side of the servo cylinder and is connected to the mounting base 14. Specifically, the guide seat 15 is provided with a guide channel, which is cylindrical. The mounting base 14 is provided with a through hole 141, and the guide channel, the through hole 141, and the PIN hole are connected. During installation, the guide channel, through hole 141, and PIN hole 21 are coaxial. The PIN pin 13 is partially located within the guide channel, which allows the PIN pin 13 to reciprocate linearly in the same direction. The tip of the PIN pin 13 passes through the mounting base 14, and the length of the PIN pin 13 passing through the mounting base 14 is greater than the thickness of the base plate 20. In this way, when the PCB board needs to be positioned and pressed, the tip of the PIN pin 13 can enter the positioning hole of the PCB board.
[0031] In some embodiments, the PIN hole 21 can be a round hole or a strip hole, which can be adjusted according to the actual needs of use. When the PIN hole 21 is a strip hole, the PIN removal mechanism 10 can also be connected to a telescopic cylinder. The telescopic cylinder drives the PIN removal mechanism 10 to extend and retract to change the position of the PIN pin 13 in the strip hole, thereby achieving positioning of different boards.
[0032] In one embodiment, the PIN stripping machine also employs the aforementioned PIN stripping mechanism 10. This mechanism allows a single drive element 11 to move a single PIN pin 13, eliminating concerns about pin jamming. Furthermore, it reduces the need for a separate PIN stripping board, resulting in a simpler overall structure and lower cost.
[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
