Description

Technical Field

[0001] This invention belongs to the field of electronic equipment manufacturing technology, and specifically relates to a lifting-type linkage flipping clamping and detection device. Background Technology

[0002] In the production of electronic devices, electrical modules such as PCB boards and power modules need to be tested for electrical conductivity using tooling fixtures. Traditional fixtures typically employ a separate design: the module is first manually or mechanically fixed, and then the probe plate is moved to align the test probes with the module contacts. This process has several drawbacks: it requires two independent actions—clamping the module and adjusting the probe plate—which increases the time spent on clamping and testing due to frequent operations; the step-by-step operation is prone to poor probe contact due to module displacement, posing a risk of positioning errors and requiring repeated calibration; and in batch testing scenarios, the increased time consumption impacts production capacity. Summary of the Invention

[0003] To simplify the clamping method of electrical modules and quickly and effectively perform clamping and testing of electrical modules, this invention proposes a lifting-type linkage flipping clamping and testing device.

[0004] A lifting-type linkage flipping clamping and detection device includes a base box, a lifting mechanism, a probe plate, and a magnetic flipping mechanism. The lifting mechanism includes a rotating shaft, a guide seat, a guide plate, a first connecting rod, and a second connecting rod. The base box includes side plates on the left and right sides and a top plate. The guide seats are symmetrically arranged inside the side plates. The side plates and guide seats have through holes in the middle. The inner side of the guide seat also has a guide groove with a width matching the guide plate. The guide plate is slidably arranged in the guide groove and cooperates with the guide seat to achieve up and down sliding. A U-shaped hole is opened at the bottom of the guide plate, and a through hole is opened at the bottom of the first connecting rod. The rotating shaft passes through the through holes of the side plates and guide seats, the U-shaped hole of the guide plate, and the through hole of the first connecting rod to form a symmetrical lifting mechanism. The top of the first connecting rod is hinged to the bottom of the second connecting rod. A transition seat is fixed to the top of the guide plate, and the inner side of the transition seat is connected to the second connecting rod. The top of the rod is hinged, and the two ends of the bottom surface of the probe plate are fixed to the adapter. Several monitoring probes are installed in the middle of the probe plate. Holes are made in the top plate at the positions corresponding to the monitoring probes so that the detection probes can pass through. The magnetic flipping structure includes a flipping claw, a strong magnet, and a magnet support. The magnet support is symmetrically arranged on the top surface of the probe plate. The strong magnet is fixed on the magnet support. Holes are made in the top plate at the positions corresponding to the magnet support so that the strong magnet and the magnet support can pass through the holes in the top plate. Hinge seats for hinged flipping claws are symmetrically arranged on the bottom surface of the top plate. Both hinge seats are located inside the two magnet supports. The bottom of the flipping claw is hinged to the hinge seat. Holes are made in the top plate at the positions corresponding to the flipping claws. The flipping claws pass through the holes in the top plate and can flip back and forth in the holes. A magnetic plate is set on the outer surface of the flipping claws.

[0005] Furthermore, limiting blocks are fixed on both sides of the inner side of the guide groove to limit the sliding of the guide plate within the guide groove.

[0006] Furthermore, a liner is installed inside the hole at the bottom of the first connecting rod to increase the friction with the rotating shaft, so that the rotating shaft drives the first connecting rod to rotate synchronously.

[0007] Furthermore, the rotating shaft extends outward from either side and connects to a handle.

[0008] The beneficial effects of this invention are as follows: Through a magnetic-mechanical coupling linkage design, single-action driven clamping and detection are completed simultaneously. A single rotation of the handle synchronously triggers the probe plate to rise and fall for probe detection. At the same time, the conversion of the like-pole repulsion and unlike-pole attraction between the magnet and the magnetic suction plate precisely controls the movement of the flipping claw, allowing the flipping claw to open and close for clamping, eliminating step-by-step operations and shortening clamping time. The consistent movement of the flipping claws on both sides avoids module displacement caused by off-center loading. The limit block and the pad respectively eliminate the risk of guide plate slippage and shaft free rotation, improving the accuracy of the movement. In the released state, the flipping claw can follow the strong magnet to flip as the probe plate moves upward, achieving clamping of the electrical module. In the clamped state, the flipping claw can follow the strong magnet to flip as the probe plate moves downward, achieving release of the electrical module. The magnetic adaptive clamping and mechanical movement are synchronized, ensuring probe contact accuracy and reducing positioning errors. Attached Figure Description

Detailed Implementation

[0014] Example 1: A lifting linkage flipping clamping and detection device includes a base box 5, a lifting mechanism, a probe plate 9, and a magnetic flipping mechanism. The lifting mechanism includes a rotating shaft 12, a guide seat 13, a guide plate 14, a first connecting rod 19, and a second connecting rod 20. The base box 5 includes side plates 11 on the left and right sides and a top plate 17. The guide seat 13 is symmetrically arranged inside the side plates 11. The side plates 11 and the guide seat 13 are provided with through holes in the middle. The inner side of the guide seat 13 is also provided with a guide groove with a width matching that of the guide plate 14. The guide plate 14 is slidably arranged in the guide groove and cooperates with the guide seat to achieve up and down sliding. Limiting blocks 16 are fixed on both sides of the inner side of the guide groove to limit the sliding of the guide plate 1 in the guide groove. A U-shaped hole is provided at the bottom of the guide plate 14, and a through hole is provided at the bottom of the first connecting rod 19. The rotating shaft 12 passes through the through holes of the side plate 11 and the guide seat 13, the U-shaped hole of the guide plate 14, and the through hole of the first connecting rod 19 to form a symmetrical lifting mechanism. A pad 18 is provided in the through hole at the bottom of the first connecting rod 19 to increase the friction with the rotating shaft 12, so that the rotating shaft 12 drives the first connecting rod 19 to rotate synchronously. The rotating shaft 12 extends outward from either side and connects to the handle 10. The top of the first connecting rod 19 is hinged to the bottom of the second connecting rod 20. The top of the guide plate 14 is fixed with an adapter 15, and the inner side of the adapter 15 is hinged to the top of the second connecting rod 20. The two ends of the bottom surface of the probe plate 9 are fixed on the adapter 15 respectively. Several monitoring probes 8 are installed in the middle of the probe plate 9. Holes that allow the detection probes 8 to pass through are provided at the positions corresponding to the monitoring probes 8 on the top plate 17. The magnetic flipping structure includes a flipping claw 2, a strong magnet 6, and a magnet support 7. The magnet support 7 is symmetrically arranged on the top surface of the probe plate 9. The strong magnet 6 is fixed on the magnet support 7. Holes are made in the top plate 17 at positions corresponding to the magnet support 7, so that the strong magnet 6 and the magnet support 7 can pass through the holes in the top plate 17. Hinge seats 4 for hinged flipping claw 2 are symmetrically arranged on the bottom surface of the top plate 17, and both hinge seats 4 are located inside the two magnet supports 7. The bottom of the flipping claw 2 is hinged to the hinge seats 4. Holes are made in the top plate 17 at positions corresponding to the flipping claw 2. The flipping claw passes through the holes in the top plate 17 and can flip back and forth in the holes. A magnetic suction plate 1 is arranged on the outer surface of the flipping claw 2. When the strong magnet 6 moves to the lower part of the magnetic suction plate 1, the flipping claw 2 rotates outward under the weight of its own top. When the strong magnet 6 moves to the upper part of the magnetic suction plate 1, it pushes the flipping claw 2 inward and flips it, realizing the clamping and releasing of the flipping claw 2.

[0015] In use, the electrical module 3 is placed between the flipping claws 2. The operator turns the handle 10, causing the rotating shaft 12 to rotate. The rotating shaft 12 drives the crankshaft connecting rod 19, which in turn moves the probe plate 9 upward. The strong magnet 6 moves upward, causing the flipping claws 2 to rotate inward and clamp the electrical module 3. At the same time, the detection probe 8 also moves upward and contacts the electrical module 3 for testing. After the test is completed, the handle 10 is turned in the opposite direction, causing the probe plate 9 to move downward. The flipping claws 2 release, and the detection probe 8 disengages from the electrical module, completing the test and allowing the electrical module 3 to be removed.
