Description

Technical Field

[0001] This utility model relates to the field of laser processing, and more specifically, to a laser PCB splitting machine connecting device. Background Technology

[0002] Electronic circuit boards are important electronic components and serve as the support for electronic components. In recent years, as electronic components have gradually developed towards miniaturization, micro-miniaturization, and integration, higher requirements have been placed on electronic circuit boards, which serve as the support for electronic components.

[0003] As a commonly used processing equipment in electronic circuit boards, laser depaneling machines use high-energy laser beams to irradiate the surface of PCB and FPC circuit boards. By controlling the energy density, frequency, speed, and number of processing times of the laser beam, the circuit boards are vaporized and cut. They have advantages such as a wide range of depaneling types, smooth cuts, and narrow kerfs.

[0004] To improve the efficiency of laser PCB separation, laser PCB separation machines are often equipped with a conveyor track mechanism to transfer electronic circuit boards to the processing station. However, to protect the workers, the protective door of the laser PCB separation machine needs to be closed when it is working. Therefore, the laser PCB separation machine needs to transfer the external conveyor mechanism to the board receiving device on the conveyor track mechanism when loading the board, and the loading device needs to be retracted when the laser PCB separation machine is working, so as to avoid affecting the closing of the protective door. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, a laser PCB splitting machine assembly device is provided.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a laser PCB splitting machine assembly device, including a conveying track mechanism. Two folding track mechanisms are provided at both ends of the conveying direction of the conveying track mechanism. The two folding track mechanisms are arranged opposite each other and spaced apart. Each folding track mechanism includes a track rod and a folding rod. One end of the track rod is connected to the conveying track mechanism. A first driving wheel and a first driven wheel are rotatably arranged on the surface of the track rod opposite to the other folding track mechanism. A first conveyor belt that cooperates with the first driven wheel is provided on the first driving wheel. The folding rod is hinged to the end of the track rod away from the conveying track mechanism. A rotating mechanism that drives the folding rod to rotate is provided on the track rod. A second driving wheel and a second driven wheel are provided on the surface of the folding rod opposite to the other folding track mechanism. A second conveyor belt that cooperates with the second driven wheel is provided on the second driving wheel. A synchronous drive mechanism that drives the first driving wheel and the second driving wheel to rotate synchronously is provided on the track rod.

[0007] Preferably, the synchronous drive mechanism includes a drive motor, which is mounted on the track rod at one end away from the other folding track mechanism. The output shaft of the drive motor is connected to the corresponding first drive wheel, and the drive motor is provided with a synchronous transmission mechanism that transmits power synchronously to the second drive wheel.

[0008] Preferably, the synchronous transmission mechanism includes two synchronous pulleys. A synchronous shaft is fixedly mounted on the second driving pulley. The synchronous shaft is rotatably mounted on and passes through the folding rod. The two synchronous pulleys are respectively fixed on one end of the synchronous shaft passing through the folding rod and on the output shaft of the drive motor. Synchronous belts are provided on the two synchronous pulleys to cooperate with the synchronous transmission.

[0009] Preferably, the output shaft of the drive motor is connected to a transmission shaft, the transmission shaft is rotatably connected to the track rod, and the transmission shaft passes through the track rod and is fixedly connected to the first drive wheel.

[0010] Preferably, the first driving wheel and the first driven wheel are respectively located at the end of the track rod away from the conveying track mechanism and the end close to the conveying track mechanism, and the second driving wheel and the second driven wheel are respectively located at the end of the folding rod close to the conveying track mechanism and the end away from the conveying track mechanism.

[0011] Preferably, the rotating mechanism includes a cylinder that is hinged to the track rod, and the output end of the cylinder is hinged to the folding rod.

[0012] Preferably, a tensioning wheel is provided between the first driving wheel and the first driven wheel. There are three tensioning wheels, which are located in the middle between the first driving wheel and the first driven wheel. Two of the three tensioning wheels are arranged at intervals and contact the outer ring of the first conveyor belt. The remaining tensioning wheel is located between the other two tensioning wheels and contacts the inner ring of the first conveyor belt. The three tensioning wheels are arranged in a triangular pattern.

[0013] Preferably, the track rod is provided with two induction sensors for sensing the feeding, with the two sensors located above the end of the folding rod connected to the track rod and above the end of the track rod away from the folding rod, respectively.

[0014] The beneficial effects of this utility model are as follows: When the laser PCB separator needs to work, the rotating mechanism drives the folding rod to rotate, making the folding rod vertical, thereby completing the folding of the folding rod and avoiding affecting the closing of the protective door. When the laser PCB separator needs to load materials onto the conveyor track mechanism, the protective door opens, and the rotating mechanism drives the folding rod to rotate 90°, making the folding rod horizontal, thus completing the connection between the folding rod and the external conveyor mechanism. At this time, the synchronous drive mechanism drives the first drive wheel and the second drive wheel to rotate synchronously, thereby allowing the first conveyor belt and the second conveyor belt to transport materials.

Therefore, they should not be construed as limitations on this utility model.

[0021] Examples of embodiments of this utility model Figures 1 to 4As shown, a laser PCB splitting machine assembly device includes a conveyor track mechanism 1, which is a double-row synchronous belt conveyor for conveying circuit boards. The double-row synchronous belt conveyor consists of two parallel synchronous belt conveyors. The bottom sides of the circuit board are respectively located on the two synchronous belt conveyors of the double-row synchronous belt conveyor. The conveying direction of the double-row synchronous belt conveyor is left-right. Two folding track mechanisms 2 are provided at both ends of the conveying direction of the conveyor track mechanism 1, that is, two folding track mechanisms 2 are provided at both ends of the double-row synchronous belt conveyor. The two folding track mechanisms 2 are arranged opposite each other and spaced apart. That is, two folding track mechanisms 2 are provided at both ends of the two synchronous belt conveyors of the double-row synchronous belt conveyor.

A first conveyor belt 24 that cooperates with the first driven wheel 23 is mounted on the first driving wheel 22. The folding rod 21 is hinged to the end of the track rod 20 away from the conveying track mechanism 1. A rotating mechanism that drives the folding rod 21 to rotate is mounted on the track rod 20. A second driving wheel 25 and a second driven wheel 26 are mounted on the surface of the folding rod 21 opposite to another folding track mechanism. That is, a second driving wheel 25 and a second driven wheel 26 are rotatably mounted on the rear end face of the front folding rod 21, and a second driving wheel 25 and a second driven wheel 26 are rotatably mounted on the front end face of the rear folding rod 21.

[0022] When the laser PCB separator needs to work, the rotating mechanism drives the folding rod 21 to rotate, making the folding rod 21 vertical, thereby completing the folding of the folding rod 21 and avoiding affecting the closing of the protective door. When the laser PCB separator needs to load materials onto the conveyor track mechanism 1, the protective door opens, and the rotating mechanism drives the folding rod 21 to rotate 90°, making the folding rod 21 horizontal, completing the connection between the folding rod 21 and the external conveyor mechanism.

The second driving wheel 25 and the second driven wheel 26 are respectively located at the end of the folding rod 21 close to the conveying track mechanism 1 and the end away from the conveying track mechanism 1, thereby reducing the synchronous transmission distance of the first driving wheel 22 and the second driving wheel 25.
