Description

Technical Field

[0001] The present invention relates to the field of mobile phone assembly equipment, and more particularly to a fully automatic assembly machine for mobile phone PCBA boards. Background Art

[0002] A mobile phone is assembled from multiple parts such as an upper frame, a middle frame, a PCBA board, a camera, a fingerprint module, a screen, various sensors, a fingerprint module, buttons, etc. With the vertical development of the industry, mobile phone assembly is developing towards automation and unmanned operation. Among the many assembly processes of mobile phones, assembling the PCBA board into the mobile phone frame is one of the key processes.

[0003] The mobile phone PCBA board refers to a circuit board on which many electronic components have been mounted on a PCB blank board through the SMT process. After the mobile phone PCBA board is completed with SMT, in order to avoid contamination of the PCBA board, a layer of packaging film is coated on the surface of the PCBA board. The packaging film covers many electronic components to ensure that the PCBA board is not contaminated during transportation. Therefore, before the PCBA board is assembled into the mobile phone frame, the packaging film on the PCBA board needs to be removed first and then assembled into the mobile phone frame. Also, due to the thin thickness of the PCBA board and it being easily damaged by force, this complex structure has restricted the development of automatic equipment for mobile phone PCBA boards. To ensure precise positioning, manual assembly is currently used, but manual operation has low productivity, and there is no device on the market that can automatically assemble the PCBA board into the mobile phone frame.

[0033] As Figure 1 shown, a fully automatic assembly machine for mobile phone PCBA boards includes a workbench 1, a PCBA board conveying device 2 and a pick-and-place manipulator 3 installed on the workbench 1. The PCBA board conveying device 2 drives the PCBA board storage box to the loading position. The PCBA board storage box contains multiple PCBA boards. The pick-and-place manipulator 3 is located on the side of the PCBA board conveying device 2. A transfer film removal device 4, a PCBA board assembly device 5, a mobile phone frame conveying device 6, and an automatic screw driving device 7 are also installed on the workbench 1.

The film removal positioning mechanism clamps and positions the mobile phone PCBA board to prevent deviation during film tearing. The film tearing rotary cylinder 42 is located on the side of the film removal fixture plate 41. The film tearing rotary cylinder 42 drives the film tearing extension cylinder to rotate. An opening 41b is provided on the side of the positioning groove 41a. The film tearing extension cylinder 44 drives the film tearing clamping cylinder to extend or retract. When the film tearing rotary cylinder 42 drives the film tearing extension cylinder 43 and the film tearing clamping cylinder 44 to rotate to a position aligned with the opening 41b, the film tearing extension cylinder 43 drives the film tearing clamping cylinder 44 to extend. The end of the film tearing clamping cylinder 44 enters the positioning groove 41a from the opening 41b. The film tearing clamping cylinder 44 clamps the packaging film on the surface of the mobile phone PCBA board and is ready to tear it. Specifically, the film removal positioning mechanism includes a first cylinder 47, a first positioning block 48, a second cylinder 49, and a second positioning block 410.

Above the X-axis movement plate 53, the Y-axis movement module 54 is installed. The Y-axis movement module 54 drives the Y-axis movement plate 55 to move left and right in the Y direction. On the side of the Y-axis movement plate 55, the Z-axis movement module 56 is installed. The Z-axis movement module 56 drives the L-shaped Z-axis movement plate 57 to move up and down in the Z direction. Above the side of the L-shaped Z-axis movement plate 57, the R-axis rotating table 58 is installed. The R-axis rotation 8 drives the rotating shaft 59 to rotate in the R direction. At the bottom of the rotating shaft 59, the L-shaped rotating frame 510 is installed. On the left side of the L-shaped rotating frame 510, the W-axis rotating table 511 is installed. The W-axis rotating table 511 drives the suction cup mounting seat 512 on the right side to rotate in the W direction. At the bottom of the suction cup mounting seat 512, the pick-up suction cup 513 is installed. The pick-up suction cup 513 sucks the PCBA board 14. Specifically, the X-axis movement module 52, the Y-axis movement module 54, and the Z-axis movement module 56 cooperate with each other to make the pick-up suction cup 513 move a large displacement to the upper part of the PCBA board 14 and then suck the PCBA board 14. Then, the X-axis movement module 52, the Y-axis movement module 54, and the Z-axis movement module 56 cooperate again to make the pick-up suction cup move close to the mobile phone middle frame with the PCBA board 14. The R-axis rotating table 58 and the W-axis rotating table 511 cooperate with each other for fine adjustment to make the pick-up suction cup rotate and change the orientation with the PCBA board and gradually obliquely insert it into the mobile phone middle frame. The assembly is fast. In addition, a plasma fan 515 is installed at the assembly support frame 51. The plasma fan 515 has an anti-static effect. And a CCD camera 516 is installed inside the Y-axis movement plate 55. The CCD camera 516 is used to photograph the materials below for convenient positioning. The R-axis rotating table 58 and the W-axis rotating table 511 are hollow rotating platforms. The PCBA board assembly device 5 is flexible in operation, precise in assembly, does not require manual holding of the PCBA board for assembly, and has a high degree of automation. In addition, the L-shaped Z-axis movement plate and the L-shaped rotating frame are L-shaped, which helps to save space and better install the R-axis rotating table and the W-axis rotating table.

The belt conveyor mechanism 62 drives the mobile phone frame to move from the front end to the rear end of the mobile phone frame conveying track rack. An assembly positioning mechanism 63 and a screw driving positioning mechanism 63 are installed in the middle of the mobile phone frame conveying track rack 61. When the mobile phone frame reaches the assembly station, the assembly positioning mechanism 63 positions and clamps the mobile phone frame. When the mobile phone frame reaches the screw driving station, the screw driving positioning mechanism 64 clamps the mobile phone frame. Specifically, the assembly positioning mechanism 63 includes an assembly positioning cylinder 631, an assembly lifting table 632, an assembly left clamping cylinder 633, and an assembly right clamping cylinder 634. The assembly positioning cylinder 631 drives the assembly lifting table 632 to rise, thereby lifting the mobile phone frame off the track rack. The assembly left clamping cylinder 633 and the assembly right clamping cylinder 634 cooperate with each other to clamp the mobile phone frame to prevent deviation during the assembly of the PCBA board. In addition, the screw driving positioning mechanism 64 includes a screw driving positioning cylinder 641, a screw driving lifting table 642, a left pressing cylinder 643, and a right pressing cylinder 644.

The moving module is composed of an X-axis moving module, a Y moving module, and a Z moving module. Its principle is the same as that of the moving module of the PCBA board assembly device 5 and will not be described in detail. The moving module drives the power screwdriver 72 and the CCD camera 73 to move. A screw feeder (not shown) conveys screws to the PCBA board. The power screwdriver 72 tightens the screws, and the CCD camera 73 takes pictures for positioning to facilitate accurate screw driving.

[0038] As Figure 13 and 14 shown, the PCBA board conveying device 2 includes a PCBA board conveying track rack 21, a belt conveyor mechanism, and a lifting cylinder 23. The belt conveyor mechanism is installed inside the PCBA board conveying track rack 21. The belt conveyor mechanism drives the PCBA board storage box to move from the front end to the rear end of the PCBA board conveying track rack. The lifting cylinder 23 lifts the PCBA board storage box at the end to facilitate the picking manipulator 3 to pick up the materials.
