Description

A PCBA board picking and transferring device Technical Field

[0001] This utility model relates to the technical field of PCBA board picking devices, and in particular to a PCBA board picking and transferring device. Background Technology

[0002] PCBA boards, or Printed Circuit Board Assemblies, often require transfer from lower conveyor belts to upper conveyor belts during their production process to connect different processes. Traditional transfer methods rely heavily on manual operation, which is not only inefficient but also prone to damage to the PCBA boards due to human error, affecting product quality.

[0003] Meanwhile, some existing factories also have robotic arms for picking up and placing PCBA boards. However, during the transfer between upper and lower layers, the angle of the PCBA board needs to be changed, which cannot guarantee that the PCBA board will move horizontally. As a result, when some components are inserted into the PCBA board, they are prone to falling off, which cannot meet the need for stable movement and can easily reduce the product qualification rate. Summary of the Invention

[0004] This invention solves the problems in related technologies and proposes a PCBA board picking and transferring device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The adjustable plate is rotatably mounted in the base plate, and an angle motor for driving the adjustable plate to rotate is fixedly mounted on the rear end face of the base plate. A connecting swing arm is mounted on the front end of the adjustable plate. One end of the connecting swing arm is fixedly connected to the adjustable plate, and an extension rod is inserted into the other end of the connecting swing arm. The extension rod is slidably connected to the connecting swing arm, and a driving component for driving the extension rod to move is mounted on the outer surface of the connecting swing arm. A stabilizing housing is rotatably mounted on the head of the extension rod, and adsorption components are symmetrically mounted on both ends of the stabilizing housing.

[0007] As a preferred embodiment, the adjustable plate includes a rotating base and an outer shaft for mounting a connecting swing arm. The outer shaft is mounted on the front end face of the rotating base and is integrally formed with the rotating base.

The drive motor is fixedly mounted on the outer side of the guide housing, one end of the threaded rod is connected to the output end of the drive motor, and a connecting screw tube that mates with the threaded rod is fixedly mounted on the slide rod.

[0011] As a preferred embodiment, the stabilizing housing includes a middle sleeve and an outer shell, the outer shell being sleeved and fixed on the outer side of the middle sleeve, and a load-bearing bar being fixedly installed in the middle of the lower end face of the outer shell.

[0012] As a preferred embodiment, the adsorption assembly includes a bending frame and an electric suction cup, wherein the bending frame is fixedly installed on the outer side of the housing base, and the electric suction cup is fixedly installed in the bending frame.

[0027] Referring to Figures 1, 2, and 3, a PCBA board handling and transfer device includes a device frame 1. The device frame 1 includes a base plate 11 and an adjustable tray 12. The adjustable tray 12 is rotatably mounted in the base plate 11, and an angle motor for driving the adjustable tray 12 to rotate is fixedly mounted on the rear end face of the base plate 11. A connecting swing arm 2 is mounted on the front end of the adjustable tray 12. One end of the connecting swing arm 2 is fixedly connected to the adjustable tray 12, and an extension rod 3 is inserted and mounted on the other end of the connecting swing arm 2. The extension rod 3 is slidably connected to the connecting swing arm 2, and a driving component 4 for driving the extension rod 3 to move is mounted on the outer surface of the connecting swing arm 2. A stabilizing housing 5 is rotatably mounted on the head of the extension rod 3, and adsorption components 6 are symmetrically mounted on both ends of the stabilizing housing 5. By driving the adjustable tray 12 to rotate through the angle motor, the angle of the connecting swing arm 2 can be adjusted, allowing the adsorption components 6 to flexibly switch positions between the lower conveyor belt 8 and the upper conveyor belt 7, facilitating the handling and transfer of PCBA boards. The sliding connection between the extension rod 3 and the connecting swing arm 2, combined with the drive of the drive component 4, allows for changes in the extension length of the extension rod 3, further expanding the working range of the adsorption assembly 6 and improving the flexibility and applicability of the device. The stabilizing base 5 provides a stable mounting foundation for the adsorption assembly 6 and ensures that the stabilizing base 5 remains vertical during movement, guaranteeing the stability of the PCBA board during handling and transfer. The adjustable disk 12 includes a rotating base 121 and an outer shaft 122 for mounting the connecting swing arm 2. The outer shaft 122 is mounted on the front end face of the rotating base 121 and is integrally formed with the rotating base 121. The integrally formed structure of the rotating base 121 and the outer shaft 122 in the adjustable disk 12 ensures the strength and stability of the structure. The outer shaft 122 provides reliable support for the mounting of the connecting swing arm 2, allowing the connecting swing arm 2 to rotate stably with the rotation of the adjustable disk 12, reducing swaying and errors caused by structural instability and improving the working accuracy of the device.

[0028] Referring to Figure 2, the connecting swing arm 2 includes a guide shell 21 and a connecting end 22. The connecting end 22 is installed at one end of the guide shell 21 and is fixedly connected to the guide shell 21. This fixed connection between the guide shell 21 and the connecting end 22 ensures the overall strength of the connecting swing arm 2 and provides guidance for the sliding of the extension rod 3. The guide shell 21 guides the extension rod 3 to slide along a specific direction, ensuring smoother and more accurate movement of the extension rod 3, thereby improving the operational stability of the device.

[0029] Referring to Figure 2, the extension rod 3 includes a sliding rod portion 31 and a mounting shaft 32 for rotatably mounting the stabilizing housing 5. The sliding rod portion 31 is slidably mounted in the guide housing 21, and the mounting shaft 32 is fixedly mounted on the outer end of the sliding rod portion 31. The sliding rod portion 31 of the extension rod 3 is slidably mounted in the guide housing 21, allowing the extension rod 3 to slide flexibly on the connecting swing arm 2, thereby adjusting its length. The mounting shaft 32 provides support for the rotatable mounting of the stabilizing housing 5, enabling the stabilizing housing 5 to rotate according to actual needs, further enhancing the flexibility and adaptability of the adsorption assembly 6, and facilitating better handling and placement of PCBA boards.

[0030] Referring to Figure 3, the driving component 4 includes a drive motor 41 and a threaded rod 42. The drive motor 41 is fixedly mounted on the outer surface of the guide housing 21. One end of the threaded rod 42 is connected to the output end of the drive motor 41. A connecting threaded tube 311 that mates with the threaded rod 42 is fixedly mounted on the sliding rod portion 31. The driving component 4 adopts a combination of the drive motor 41 and the threaded rod 42. The drive motor 41 drives the threaded rod 42 to rotate, and the engagement of the threaded rod 42 with the connecting threaded tube 311 converts the rotational motion into the linear motion of the extension rod 3. This transmission method has the advantages of high transmission accuracy and good stability, and can accurately control the movement distance of the extension rod 3, thereby improving the working accuracy and reliability of the device.

[0031] Referring to Figures 4 and 5, the stabilizing housing 5 includes a middle sleeve 51 and an outer shell 52. The outer shell 52 is fitted and fixed to the outer surface of the middle sleeve 51, and a load-bearing bar 53 is fixedly installed in the middle of the lower end face of the outer shell 52. The structure in which the middle sleeve 51 and the outer shell 52 are fitted and fixed together increases the overall strength of the stabilizing housing 5. The installation of the load-bearing bar 53 lowers the center of gravity of the stabilizing housing 5, improves the stability of the stabilizing housing 5, reduces shaking during the handling and transfer of PCBA boards, and ensures the safety and stability of the PCBA boards.

[0032] Referring to Figure 6, the adsorption assembly 6 includes a bending frame 61 and an electric suction cup 62. The bending frame 61 is fixedly installed on the outer surface of the housing 52, and the electric suction cup 62 is fixedly installed in the bending frame 61. The bending frame 61 of the adsorption assembly 6 provides a stable mounting position for the electric suction cup 62. The electric suction cup 62 can generate a strong adsorption force to firmly adsorb the PCBA board, ensuring that the PCBA board will not fall off during handling and transfer, thus improving the working reliability of the device.

[0033] In this embodiment, when it is necessary to remove the PCBA board from the lower conveyor belt, the angle motor is activated to drive the adjustable disk 12 to rotate, causing the connecting swing arm 2 to move the adsorption assembly 6 above the lower conveyor belt. The drive motor 41 is then activated, driving the threaded rod 42 to rotate. Through the cooperation of the threaded rod 42 and the connecting screw tube 311, the extension rod 3 extends, moving the adsorption assembly 6 to a suitable position. The electric suction cup 62 is then activated, generating adsorption force to hold the PCBA board on the lower conveyor belt. The drive motor 41 is activated again to retract the extension rod 3. Then, the angle motor is activated to drive the adjustable disk 12 to rotate, moving the adsorption assembly 6 with the PCBA board above the upper conveyor belt. The drive motor 41 is activated again to extend the extension rod 3, placing the PCBA board on the upper conveyor belt. Finally, the electric suction cup 62 is turned off, completing the PCBA board removal and transfer process.

[0034] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
