[0002] The motherboard, also called the mainboard, system board, or motherboard, is one of the most basic and important components of a computer. A motherboard is generally a rectangular circuit board on which the main circuitry of the computer is installed. It typically includes a BIOS chip, I / O control chip, keyboard and front panel control switch interfaces, indicator light connectors, expansion slots, and DC power supply connectors for the motherboard and expansion cards. Before use, the motherboard needs to undergo circuit and functional testing to ensure it functions properly; therefore, a professional motherboard testing device is required.

[0003] For example, patent CN212781110U discloses a motherboard testing device, which includes an alarm light, a toolbox, a device body, and an electrical control box.

[0031] Figure 1 This is the working state of Embodiment 1 of the present invention.

[0032] The main board moving device 1 is in working condition, driving the main board to move; the loading device 2 is in working condition, loading materials onto the main board; the moving feeding device 3 is in working condition, carrying and moving the materials; the plug mounting device 4 is in a stationary state, waiting to fix the position of the wire head 501; and the power supply device 5 is in working condition, waiting to supply power to the main board.

[0033] Working principle of the invention: Figure 1 The invention is described in terms of usage and corresponding scenarios. The motherboard moving device 1 is used to provide a working position for the motherboard and drive the motherboard to move. The loading device 2 is used to pick up materials from the moving feeding device 3 and install the materials on the motherboard. The moving feeding device 3 is used to provide a storage position for the materials and move the materials to the designated picking position. The plug mounting device 4 is used to provide a fixed position for the power plug. The power supply device 5 is used to provide power for motherboard testing.

[0034] Taking Embodiment 1 as an example, before testing the motherboard, the present invention requires the installation of components such as graphics cards, hard drives, and chips on the motherboard. The motherboard moving device 1 is responsible for providing the working position and changing the installation position. The moving motor 105 drives the longitudinal screw 102 to rotate, causing the first moving plate 101 to move longitudinally, thereby controlling the longitudinal position of the worktable 114. When the worktable 114 needs to rotate 90 degrees to change the installation position, the flip push rod 110 pushes the flip roller 112 forward, causing the groove plate 107 to rotate. After the flip roller 112 retracts and moves away from the groove plate 107, the positioning spring 108 pushes the positioning push rod 109 into the groove on the groove plate 107, causing the groove plate 107 to rotate a certain angle, so that the next time the flip roller 112 is pushed out, it can push the groove plate 107 to rotate. When it is necessary to install parts, the loading motor 202 drives the loading screw 203 to rotate through the belt drive, thereby controlling the lateral position of the loading slider 204. When the loading slider 204 approaches the moving feeding device 3, Conveyor belt 302 controls the designated upper housing 304 and lower housing 308 to reach the clamping position. The loading push rod 210 pushes out the loading lower plate 214, causing the loading clamping plate 212 to clamp the upper housing 304. The hexagonal head motor 213, in conjunction with the internal hexagonal screw 305, then causes the loading slider 204 to drive the upper housing 304 to the part installation position on the main board. The hexagonal head motor 213 rotates, pushing out the feeding push plate 306, causing the feeding clamping plate 307 to loosen its clamping, completing the part installation. The upper housing 304... 4 and the lower housing 308 can be designed to be different sizes to accommodate components of different sizes such as graphics cards, hard drives, and chips. After the components are installed on the motherboard, the movable housing 104 is pushed so that the workbench 114 reaches the plug mounting device 4. After aligning the power cable 501 of the power supply device 5 with the power socket of the motherboard, it is fixed above the power socket by two sets of front clamping blocks 402 and rear clamping blocks 403. When testing is required, pulling the vertical slide bar 404 can provide power to the motherboard for testing.

[0035] Specifically, such as Figures 2-4 As shown, the main board moving device 1 is responsible for providing the working position and changing the installation position. The moving motor 105 drives the longitudinal moving screw 102 to rotate, so that the first moving plate 101 moves longitudinally, thereby controlling the longitudinal position of the worktable 114. When the worktable 114 needs to rotate 90 degrees to change the installation position, the flipping push rod 110 pushes the flipping roller 112 forward, so that the groove plate 107 rotates. After the flipping roller 112 retracts away from the groove plate 107, the positioning spring 108 pushes the positioning push rod 109 into the groove on the groove plate 107, so that the groove plate 107 rotates a certain angle again, so that the next time the flipping roller 112 is pushed out, it can push the groove plate 107 to rotate. like Figures 5-8As shown, when parts need to be installed, the loading motor 202 drives the loading screw 203 to rotate via the pulley drive, thereby controlling the lateral position of the loading slider 204. When the loading slider 204 approaches the moving feeding device 3, the conveyor belt 302 controls the designated upper box 304 and lower box 308 to reach the clamping position. The loading push rod 210 pushes out the loading lower plate 214, so that the loading clamping plate 212 clamps the upper box 304. The hexagonal head motor 213 cooperates with the internal hexagonal screw 305 to make the loading slider 204 drive the upper box 304 to the part installation position on the motherboard. The hexagonal head motor 213 rotates and pushes out the feeding push plate 306, so that the feeding clamping plate 307 no longer clamps the material, completing the installation of the part. The upper box 304 and lower box 308 can be designed with different sizes to accommodate parts of different sizes such as graphics cards, hard drives, and chips. like Figure 9 , Figure 10 As shown, after the components are installed on the motherboard, the movable housing 104 is pushed so that the workbench 114 reaches the plug mounting device 4. After aligning the power cord 501 of the power supply device 5 with the power socket of the motherboard, it is fixed above the power socket by two sets of front clamping blocks 402 and rear clamping blocks 403. When testing is required, the vertical slide bar 404 is pulled to supply power to the motherboard and then test it.

[0036] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
