[0056] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0057] Please see Figures 1-9 The fully automatic PCBA board fastening equipment includes a lower support 10 and an upper support 20.

[0058] In practical use, the above solution involves manually placing the power supply back cover plate from the tray into the loading / unloading module 30, and manually placing the PCBA board from the tray into the loading / unloading module 30. Then, a six-axis robotic arm 50 automatically takes pictures and removes the PCBA board and power supply back cover plate. The robotic arm 50 uses a secondary CCD positioning system to locate the PCBA board and power supply back cover plate, and moves them to the conveyor belt module 60 for assembly and clamping, completing the assembly operation. After assembly, the conveyor belt module 60 transports the assembled products (PCBA board and power supply back cover plate). When it reaches below the screw fastening assembly 70, the screw fastening assembly 70 fastens the screws, securing the assembled PCBA board and power supply back cover plate. After the product fastening operation is completed, the conveyor belt module 60 continues to operate, moving the product to the side of the assembly discharge displacement assembly 80, where the assembly discharge displacement assembly 80 clamps and unloads the product.

[0059] In this solution, the testing instrument 90 tests the assembled and locked PCBA boards and power supply back covers to ensure the accuracy of the PCBA boards and power supply back covers during assembly.

[0060] For details, please refer to the following: Figure 4 The loading and unloading module 30 includes an assembly chamber 301, which is located on one side inside the lower support 10.

An X-axis module 505 is mounted on the bottom of the assembly frame 503. The X-axis module 505 has an X-axis slide 506 mounted on its side. The X-axis slide 506 has a first Z-axis module 507 and a second Z-axis module 508 mounted on its side. The first Z-axis module 507 is located on the side of the second Z-axis module 508. The sides of the first Z-axis module 507 and the second Z-axis module 508 are respectively mounted with two R-axis modules 509 via the Z-axis slide. The sides of the two R-axis modules 509 are respectively mounted with two material handling fixtures 5010 via the R-axis slide.

[0063] In this embodiment, a CCD camera 5061 is mounted on the side of the X-axis slide 506. The CCD camera 5061 is positioned above the CCD light source 5062, which is mounted on the side of the X-axis slide 506. A CCD lens 5063 is mounted on the bottom of the CCD camera 5061, and the CCD lens 5063 is positioned facing the CCD light source 5062.

[0064] In the above embodiments, the CCD camera 5061, CCD light source 5062 and CCD lens 5063 can perform secondary positioning of the power supply back cover and PCBA board in the material handling and assembly states, ensuring that the assembly operation of the power supply back cover and PCBA board with high precision can be achieved.

[0065] This fully automatic PCBA board fastening device utilizes a Y-axis slide 502 moving along the Y-axis on the side of the Y-axis module 501 and an X-axis slide 506 moving along the X-axis on the side of the X-axis module 505, to achieve movement of the two pick-and-place fixtures 5010 in the X and Y axes. The design of the first Z-axis module 507 and the second Z-axis module 508 enables the Z-axis lifting and lowering movement of the two pick-and-place fixtures 5010. The design of the two R-axis modules 509 enables the R-axis rotation of the two pick-and-place fixtures 5010.

[0066] The conveyor belt module 60 includes a horizontal frame 601, a drive motor 602, an anti-deviation belt 603, a servo module 604, a product carrier 605, and a product preload module 606.

The anti-deviation belt 603 is connected to the conveyor wheel via an external key. The anti-deviation belt 603 is movably disposed inside the horizontal frame 601, and its tension is adjusted by a tension adjustment system mounted on the side. A detection instrument 90 is mounted above the horizontal frame 601. The servo module 604 is mounted on the side of the horizontal frame 601, the product carrier 605 is mounted on the top of the servo module 604, and the product preload module 606 is mounted on the top of the product carrier 605.

[0067] This fully automatic PCBA board mounting equipment, when assembling the power supply back cover and PCBA board to be assembled, allows the power supply back cover and PCBA board to be placed on top of the product pre-compression module 606 via two pick-and-place clamps 5010. The pick-and-place clamps 5010 then move the PCBA board into the power supply back cover at the top of the product pre-compression module 606, where the pre-compression module 606 performs a pre-compression operation on the assembled power supply back cover and PCBA board. After the pre-compression operation is completed, the product (power supply back cover and PCBA board) is moved to the top of the anti-deviation belt 603 via the pick-and-place clamps 5010, and the anti-deviation belt 603 is driven by the drive motor 602, thus moving the product (power supply back cover and PCBA board).

A clamp 708 is mounted on the bottom of the screwdriver bar 707.

[0069] This fully automatic PCBA board fastening equipment utilizes a first drive cylinder 702 and a second drive cylinder 704 to operate during screw assembly operations on products (power supply back cover and PCBA board). This drives the screw clamping jaws 708 to move up and down a second time, achieving screw clamping and lifting assembly operations. A servo electric screwdriver 706, by driving the screwdriver bar 707 and the jaws 708, assembles the screws mounted inside the jaws 708 into the product (power supply back cover and PCBA board).

[0070] The assembly of the discharge displacement component 80 includes a lower mounting base 801, which is mounted on the other side of the top of the lower support 10.
