Technical Field

[0001] This invention relates to the field of motherboard testing fixture technology, specifically a gas detector motherboard testing fixture. Background Technology

[0002] In the production process of gas detector motherboards, performance testing is conducted to ensure product reliability. Before testing, the gas detector motherboard needs to be placed on a fixture for positioning and fixation. Then, the electrical components on the motherboard are tested to ensure they function correctly. Existing gas detector motherboard testing fixtures require manual placement of the motherboard into the fixture's slot, followed by manual activation of the positioning and fixing structures. However, incorrect button presses during manual operation can cause the motherboard to shift, affecting test results. Furthermore, after activating the positioning structure, the positioning blocks sometimes lift the motherboard, causing further positional shifts. Additionally, most existing gas detector motherboard test boards are fixed, preventing the conductive posts on the test board from making tight contact with the electrical components after positioning and fixation, thus affecting the testing structure. Moreover, the motherboard is inconvenient to remove after testing, making the device less convenient to use. To address these issues, a new gas detector motherboard testing fixture is needed.

The drive rod 310 drives the lateral moving link 311 to move. While the lateral moving link 311 moves, the connecting rod 312 drives the longitudinal moving link 313 to move. The movement of both the lateral and longitudinal moving links 311 and 313 drives the drive slide plate 315 to move. As the drive slide plate 315 moves, the Z-shaped slide groove 316 and drive lever 317 drive the lifting slide rod 318 to move upwards. As the lifting slide rod 318 moves upwards, the connecting shaft 320 drives the connecting rotating plate 321 to... The connecting shaft on the fixed column 331 rotates around the axis. When the connecting plate 321 rotates, it drives the adjusting bolt 322 and the fixing block 323 to rotate. After the fixing block 323 rotates, it can fix the detector motherboard on the motherboard placement platform 302. At the same time as the fixing block 323 rotates, the transverse moving link 311 and the longitudinal moving link 313 drive the moving slide plate 326 and the connecting slider 327 to move on the connecting slide rail 328 through the connecting pull rod 324 and the fixed connecting seat 325. When the moving slide plate 326 moves, it drives the connecting bolt 329 and the positioning top plate 330 to move towards the center, thereby centering the detector motherboard. This allows the detector motherboard to perform center positioning and fixing work at the same time. At the same time, when positioning and fixing the detector motherboard, the adjusting bolt 322 and the connecting bolt 329 can be rotated according to the actual situation to adjust the pressure of the fixing block 323 on the detector motherboard and the thrust of the positioning top plate 330 on the detector motherboard, making the center positioning and fixing of the detector motherboard more precise.

[0049] The controller 2 controls the operation of the drive motor 402. When the drive end of the drive motor 402 moves, it drives the rotating lead screw 403 to rotate. When the rotating lead screw 403 rotates, it drives the two sets of lead screw slides 404 to move in opposite directions on the side wall of the rotating lead screw 403. When the lead screw slides 404 move, they drive the connecting plate 408, the electrical connection plate 409, the multiple sets of electrical conductive posts 410 and the connecting crossbar 411 to move upward through the connecting plate 406 and the connecting seat 407. When the connecting crossbar 411 moves upward, it drives the moving top plate 417 to move downward on the side wall of the limiting guide post 419 through the rotating crank 412, the connecting seat 413, the connecting slider 414 and the connecting bracket 416. When the electrical connection plate 409 and the multiple sets of electrical conductive posts 410 move upward, the electrical conductive posts 410 and the electrical components on the detector motherboard can make close contact, improving the accuracy of the detector motherboard test.

[0050] The electric telescopic rod 303 is controlled by controller 2. When the drive end of the electric telescopic rod 303 moves, it drives the moving rack 304 to move. When the moving rack 304 moves, it drives the rotating gear 306, rotating rod 307, rotating turntable 308 and connecting shaft 309 to rotate. When the connecting shaft 309 rotates, it drives the lateral moving link 311 to move via the drive rod 310. When the lateral moving link 311 moves, it drives the longitudinal moving link 313 to move via the connecting rod 312. When the lateral moving link 311 and the longitudinal moving link 313 move, they drive the drive slide plate 315 to move. When the drive slide plate 315 moves, it passes through the Z-shaped slide groove 316 and the drive lever 317. The lifting slide bar 318 moves downward. When the lifting slide bar 318 moves downward, it drives the connecting rotating plate 321 to rotate around the connecting shaft on the fixed column 331 via the connecting shaft 320. When the connecting rotating plate 321 rotates, it drives the adjusting bolt 322 and the fixed pressure block 323 to tilt upward and rotate. At the same time as the fixed pressure block 323 rotates, the lateral moving link 311 and the longitudinal moving link 313 drive the moving slide plate 326 and the connecting slider 327 to move on the connecting slide rail 328 via the connecting pull rod 324 and the fixed connecting seat 325. When the moving slide plate 326 moves, it drives the connecting bolt 329 and the positioning top plate 330 to move in all directions, thereby releasing the positioning and fixing of the detector main board.

[0051] Subsequently, the drive motor 402 is controlled by the controller 2. When the drive end of the drive motor 402 moves, it drives the rotating lead screw 403 to rotate. When the rotating lead screw 403 rotates, it drives the two sets of lead screw slides 404 to move in opposite directions on the side wall of the rotating lead screw 403. When the lead screw slide 404 moves, it drives the connecting plate 408, the electrical connecting plate 409, the multiple sets of electrical conductive posts 410 and the connecting crossbar 411 to move downward through the connecting rotating plate 406 and the connecting connecting seat 407. When the connecting crossbar 411 moves downward, it drives the moving top plate 417 to move upward on the side wall of the limiting guide post 419 through the rotating crank 412, the connecting connecting seat 413, the connecting slider 414 and the connecting bracket 416. When the moving top plate 417 moves upward, it can lift the detector motherboard on the motherboard placement platform 302 upward, making it convenient to pick up the detector motherboard.

[0052] Among them, the controller 2, tester 5, electric telescopic rod 303, drive motor 402, electrical connection plate 409 and electrical conductor 410 are existing components, and will not be described in detail in this solution.
