Abstract
Description
Technical Field
[0001] This utility model belongs to the field of PCB board processing technology, specifically relating to a pin machine for processing PCB boards. Background Technology
[0002] A PCB, or Printed Circuit Board, is a type of board used for connecting and supporting electronic components. It is typically composed of conductive layers and non-conductive substrates. Electronic components are connected through copper traces on the PCB to form electrical connections in electronic devices. It is widely used in various electronic products, such as mobile phones, computers, televisions, and home appliances. During PCB manufacturing, a pinning machine is used to punch pins and holes in the PCB.
[0003] For example, a Chinese patent discloses a high-precision pinning machine for PCB board processing (authorization announcement number CN210967088U). This patented technology uses a first drive motor and a second drive motor to drive the support frame and the cross plate to move, so that the drill bit can be moved to the appropriate position to make holes in the PCB board, thereby improving the drilling accuracy and efficiency.
[0004] However, most existing pinning machines use the reaction force of springs to clamp the PCB board during processing and positioning. Because of the characteristics of springs, they vibrate and deform during pinning, affecting stability and thus impacting the pinning of the PCB board. For example, the aforementioned comparative document uses the force of springs to clamp the PCB board with two pressure plates. In practical applications, when the PCB board is processed by the pinning machine, it vibrates, resulting in poor stability and affecting the processing, thus reducing its practicality.
[0005] Therefore, those skilled in the art have provided a pin-making machine for processing PCB boards to solve the problems mentioned in the background art. Utility Model Content
[0006] The purpose of this invention is to provide a pin-making machine for processing PCB boards, which can solve the problems mentioned in the background art.
[0007] The specific technical solution adopted in this utility model is as follows:
[0008] A pinning machine for processing PCB boards includes a base plate, a movable seat slidably mounted on the upper surface of the base plate, connecting plates symmetrically arranged on the upper surface of the movable seat, a top plate connected to the upper surface of the connecting plates, a connecting rod penetrating through the upper surface of the top plate, a pressure plate connected to the upper end of the connecting rod, and a lifting plate connected to the lower end of the connecting rod, an electric lifting rod installed at the middle position of the upper surface of the movable seat, and a fixed plate installed on the upper surface of the base plate in front of the movable seat, with a first cylinder installed on the front surface of the fixed plate;

[0010] The present invention is further configured such that: the fixed end of the first cylinder is mounted on the front surface of the fixed plate, and the telescopic end of the first cylinder is connected to the front surface of the movable seat.
[0011] The present invention is further configured such that: a "T"-shaped guide rail is installed on the upper surface of the base plate, and a guide groove is provided on the lower surface of the movable seat to slide relative to the guide rail.
[0012] The present invention is further configured such that the fixed end of the electric lifting rod is installed on the upper surface of the movable seat, and the telescopic end of the electric lifting rod is connected to the lower surface of the lifting plate.

[0017] The technical effects achieved by this utility model are as follows:
[0018] This utility model relates to a pinning machine for processing PCB boards. The operation of the electric lifting rod causes the lifting plate to rise and fall, which in turn causes the pressure plate connected by the connecting rod to press down on the PCB board placed on the top plate to ensure its stability. At the same time, the first cylinder causes the moving seat to move on the base plate, that is, the guide roller moves inside the guide groove, thereby achieving the purpose of automatic feeding. It has good practicality.
[0019] This utility model discloses a pinning machine for processing PCB boards. By operating the second cylinder on the moving frame, the lifting block is guided to rise and fall outside the two fixed rods. This allows for adjustment of the frame height to perform pinning on the PCB board. Simultaneously, the operation of the electric push rod moves the moving frame on the base plate, thereby adjusting the position of the motor on the frame to facilitate pinning at different locations on the PCB board. The machine has a simple structure and good practicality. Attached Figure Description

[0025] 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.
[0026] like Figure 1-3As shown, a pinning machine for processing PCB boards includes a base plate 1. A movable seat 2 is slidably mounted on the upper surface of the base plate 1. A connecting plate 21 is symmetrically arranged on the upper surface of the movable seat 2. A top plate 22 is connected to the upper surface of the connecting plate 21. A connecting rod 231 is passed through the upper surface of the top plate 22. A pressure plate 23 is connected to the upper end of the connecting rod 231, and a lifting plate 24 is connected to the lower end of the connecting rod 231. An electric lifting rod 26 is installed at the middle position of the upper surface of the movable seat 2. A fixed plate 3 is installed on the upper surface of the base plate 1 in front of the movable seat 2. A first cylinder 31 is installed on the front surface of the fixed plate 3. This arrangement uses the operation of the electric lifting rod 26 to make the lifting plate 24 rise and fall. During the rise and fall, the pressure plate 23 connected by the connecting rod 231 moves downward, thereby pressing and positioning the PCB board placed on the top plate 22 to ensure its stability. The first cylinder 31 can make the movable seat 2 slide on the base plate 1, thereby achieving the purpose of automatic feeding.
[0027] A mounting plate 4 is installed on the upper surface of the base plate 1. A guide rod 42 is installed through one side of the mounting plate 4. One end of the guide rod 42 is connected to a movable frame 5. A second cylinder 51 is installed on the upper surface of the movable frame 5. A lifting groove 53 is opened on one side of the movable frame 5. A lifting block 62 is slidably installed inside the lifting groove 53. A bracket 6 is fixed on one side of the lifting block 62. A motor 61 is installed on the upper surface of the bracket 6. This arrangement uses the operation of the second cylinder 51 on the movable frame 5 to make the lifting block 62 rise and fall inside the lifting groove 53. During the rise and fall, the height of the motor 61 can be adjusted to perform pin processing on the PCB board placed on the top plate 22.
[0028] like Figure 1 and Figure 2 As shown, the fixed end of the first cylinder 31 is installed on the front surface of the fixed plate 3, and the telescopic end of the first cylinder 31 is connected to the front surface of the movable seat 2. The upper surface of the base plate 1 is also equipped with a "T"-shaped guide rail 11, and the lower surface of the movable seat 2 is provided with a guide groove 25 that slides with the guide rail 11. This arrangement uses the operation of the first cylinder 31 to make the movable seat 2 move on the base plate 1, and when it moves, it will slide in the guide groove 25 through the guide rail 11. In this way, the purpose of automatically moving and feeding the PCB board on the top plate 22 can be achieved, and the pin processing of the PCB board can be realized.
[0029] like Figure 3 As shown, the fixed end of the electric lifting rod 26 is installed on the upper surface of the movable seat 2, and the telescopic end of the electric lifting rod 26 is connected to the lower surface of the lifting plate 24. This arrangement uses the operation of the electric lifting rod 26 to make the lifting plate 24 rise and fall below the top plate 22. During the rise and fall, the pressure plate 23 moves downward to press and position the PCB board placed on the top plate 22, thereby ensuring its stability.
[0030] like Figure 4 As shown, the fixed end of the electric push rod 41 is installed on one side of the mounting plate 4, and the telescopic end of the electric push rod 41 is connected to one side of the movable frame 5. This arrangement uses the operation of the electric push rod 41 to make the movable frame 5 move on the base plate 1, and guides it through the guide rod 42 during movement. In this way, the position of the motor 61 on the bracket 6 can be adjusted to process the PCB board.
[0031] like Figure 4 As shown, the fixed end of the second cylinder 51 is installed on the upper surface of the movable frame 5, and the telescopic end of the second cylinder 51 is connected to the upper surface of the lifting block 62. Two fixed rods 52 are symmetrically arranged inside the lifting groove 53. The lifting block 62 is slidably installed outside the two fixed rods 52. A "T"-shaped slider 54 is provided on the lower surface of the movable frame 5. A sliding groove that slides with the slider 54 is opened on the upper surface of the base plate 1. This arrangement uses the operation of the second cylinder 51 to make the lifting block 62 connected to its telescopic end rise and fall inside the lifting groove 53, and is guided by the fixed rod 52. In this way, the height of the bracket 6 can be adjusted, thereby allowing the drill bit connected to the drive end of the motor 61 to be driven down to process the PCB board.
[0032] The working principle of this utility model is as follows: When the pinning machine for processing PCB boards is used, the PCB board to be processed is first placed on the top plate 22. After placement, the electric lifting rod 26 is activated, which causes the pressure plate 23 connected to the connecting rod 231 to move downward, pressing the PCB board. After pressing and positioning, the first cylinder 31 on the front surface of the fixing plate 3 is activated, which causes the moving seat 2 to move on the bottom plate 1. This allows for automatic feeding of the PCB board on the top plate 22. During feeding, the electric push rod 41 can be used. The operation causes the movable frame 5 to move on the base plate 1, which adjusts the position of the motor 61 on the bracket 6. After reaching the position, the operation of the second cylinder 51 causes the lifting block 62 connected to its telescopic end to rise and fall inside the lifting groove 53, and is guided by the fixed rod 52. This allows the height of the bracket 6 to be adjusted, thereby allowing the drill bit connected to the drive end of the motor 61 to move down to process the PCB board. This utility model can process different positions of the positioned PCB board by using the movable seat 2 that moves back and forth on the base plate 1 and the movable frame 5 that moves left and right, which has good practicality.
