A product placement groove is provided in the middle part of the top surface of the base, and a plurality of connection terminals are provided on the front end surface of the base. The flipping mechanism includes at least two hinges and two nitrogen spring rods. One side of the at least two hinges is rotatably connected to one side of the top surface of the base, and the other side is rotatably connected to one side of the cover plate. One end of the two nitrogen spring rods is rotatably connected to the left and right sides of the cover plate, and the other end is rotatably connected to the left and right sides of the base. The base and the cover plate can be connected by flipping contact, and a plurality of probe blocks are provided on the side of the cover plate that contacts the base.

[0004] The lighting fixture disclosed in the aforementioned patent has a slot for placing panel products, which is designed to be slightly larger than the panel itself to allow for a gap. After the panel product is placed in the slot, the side of the panel product is pressed tightly by adjusting the positioning fine-tuning block to ensure precise contact between the probe and the product's pins. After testing, the positioning fine-tuning block must be loosened to remove the panel product. Therefore, when inspecting each panel product, the positioning fine-tuning block must be repeatedly adjusted, which is inconvenient and affects the efficiency of testing. Summary of the Invention

[0009] Furthermore, the pressing assembly is an L-shaped rod hinged to the fixed plate, one end of the L-shaped rod is a gripping part, and the other end of the L-shaped rod is a pushing part. When the L-shaped rod is not flipped, the lifting plate is located at the top of the guide rod. After the L-shaped rod is flipped, the lifting plate is pushed down by the pushing part.

[0010] Furthermore, the elastic member is a telescopic spring sleeved on the outer wall of the guide rod, one end of the telescopic spring is connected to the fixture body, and the other end of the telescopic spring is connected to the lifting plate.

[0028] The overall idea of ​​the present invention is as follows: the panel is placed in the placement slot, and there is space between the panel and the placement slot. When lighting normally, the L-shaped rod is flipped mainly by manual force to lower the lifting plate, and the probe contacts the pin to achieve signal conduction.

[0029] When the lifting plate descends, the lifting plate pulls the first clamping rod to move through the tension belt, drives the gear shaft to rotate, and then drives the two first clamping blocks to move, so that the first clamping block on the upper side of the panel and the second clamping blocks on the left and right sides of the panel clamp the panel. Since the first clamping block and the second clamping block move at the same time, the first clamping block and the second clamping block have a three-way simultaneous positioning function for the panel, so that the pins of the panel are aligned with the probes.

[0030] See also Figure 1 and Figure 2 The present invention provides a lighting fixture with an automatic correction function, comprising a fixture body 1, a placement groove 11 for placing a panel 6 is opened on the top surface of the fixture body 1, the size of the placement groove 11 is larger than the size of the panel 6, the lighting fixture further comprises a clamping assembly 2 arranged in the placement groove 11, the clamping assembly 2 comprises a gear shaft 21 rotatably connected to the bottom wall of the placement groove 11, the outer wall of the gear shaft 21 is meshed with a first clamping rod 22 and two second clamping rods 23, the first clamping rod 22 and the second clamping rod 23 are slidably connected in the placement groove 11, the first clamping rod 22 slides vertically along the fixture body 1, the second clamping rod 23 slides horizontally along the fixture body 1, and the movement directions of the two second clamping rods 23 are opposite; the end of the first clamping rod 22 is connected to a first clamping block 24 for clamping the upper end of the panel 6, and each second clamping rod 23 is respectively connected to a second clamping block 25 for clamping the side of the panel 6;

[0031] The top of the fixture body 1 is connected to a driving assembly 3 that moves the first clamping rod 22. The driving assembly 3 is pressed down, and the first clamping rod 22 is pulled to move by the tension belt 34, thereby driving the gear shaft 21 to rotate, and then driving the two second clamping rods 23 to move, so that the first clamping block 24 and the second clamping block 25 clamp the panel 6 at the same time, and play the function of simultaneous three-way positioning of the panel 6, so that the pins of the panel 6 are aligned with the probe 5. The side wall of the placement groove 11 is provided with a reset assembly 4 that opens the second clamping rod 23. After the lighting test is completed, the driving assembly is moved up, and the reset assembly 4 pulls the two second clamping rods 23 to move in the opposite direction, and the gear shaft 21 rotates in the opposite direction, thereby pushing the first clamping rod 22 to move in the opposite direction, so that the first clamping block 24 and the second clamping block 25 loosen the fixation on the panel 6. Therefore, during the lighting test, it is only necessary to move the driving component 3 up and down to achieve the clamping, positioning, fixing and loosening of the panel 6, without the need for repeated disassembly and assembly of the positioning fine-tuning block, which improves the convenience of the lighting test and the efficiency of the detection of the panel 6.

[0032] See also Figures 3 to 8 The driving assembly 3 includes a guide rod 31 fixed to the top of the jig body 1. The outer wall of the guide rod 31 is slidably connected to a lifting plate 32. A guide rod 33 is provided on the top of the jig body 1. The end of the first clamping rod 22 is connected to a tension belt 34. One end of the tension belt 34 passes through the jig body 1, passes around the guide rod 33, and is connected to the bottom of the lifting plate 32. A fixed plate 35 is provided on the top of the guide rod 31. The fixed plate 35 is hinged with a pressing assembly for pushing the lifting plate 32 down. The outer wall of the guide rod 31 is provided with an elastic member 37 for resetting the lifting plate 32. When the pressing assembly flips, the lifting plate 32 descends, so that the tension belt 34 pulls the first clamping rod 22 to slide vertically in the placement groove 11. When the pressing assembly is reset, the elastic member 37 pushes the lifting plate 32 up, so that the reset assembly 4 can pull the two second clamping rods 23 to move in the opposite direction, so that the first clamping block 24 and the second clamping block 25 loosen the fixation on the panel 6.

[0033] See also Figure 7 and Figure 8 The pressing component is an L-shaped rod 36 hinged to the fixed plate 35. One end of the L-shaped rod 36 is a gripping portion 361, and the other end of the L-shaped rod 36 is a pushing portion 362. When the L-shaped rod 36 is not flipped, the lifting plate 32 is located at the top of the guide rod 31. After the L-shaped rod 36 is flipped, the lifting plate 32 is pushed down by the pushing portion 362.

[0034] See also Figure 3 and Figure 4Elastic member 37 is a telescopic spring mounted on the outer wall of guide rod 31. One end of the telescopic spring is connected to the fixture body 1, and the other end is connected to the lifting plate 32. When the L-shaped rod 36 flips, the lifting plate 32 descends, compressing the telescopic spring. After the lighting test is completed, the operator flips the L-shaped rod 36 back to its original position. Once the external force is removed, the telescopic spring expands, pushing the lifting plate 32 back into its original position.

[0035] See also Figure 3 and Figure 4 , a probe 5 connected to the bottom of the lifting plate 32 is provided, which is in contact with the pins of the panel 6. After the lifting plate 32 is lowered into place, the probe 5 contacts the pins of the panel 6 to achieve signal conduction.

[0036] See also Figure 1 and Figure 2 The reset assembly 4 comprises two reset springs, one on each side of the placement slot 11. The left and right walls of the placement slot 11 are each provided with a relief groove 12. One end of the reset spring is connected to the side wall of the relief groove 12, and the other end of the reset spring is connected to the second clamping rod 23. When the lifting plate 32 rises, the reset spring is used to pull the two second clamping rods 23 to reset.

[0037] See also Figure 3 and Figure 4 The downward displacement of the lifting plate 32 is greater than the sliding displacement of the first clamping rod 22 and the second clamping rod 23. This arrangement allows the first clamping block 24 and the second clamping block 25 to simultaneously clamp the panel 6, positioning the panel 6 in three directions simultaneously. This prevents the probe 5 located at the bottom of the panel 6 from contacting the pins. This prevents the panel 6 from being properly positioned before the probe 5 is pressed down, causing poor contact between the probe 5 and the pins, and thus affecting the judgment of the lighting test results.

[0038] See also Figure 3 and Figure 4 The tension band 34 consists of a band body 341 and a first spring 342. One end of the first spring 342 is connected to the first clamping rod 22, and the other end of the first spring 342 is connected to the band body 341. The end of the band body 341 away from the first spring 342 passes around the guide rod 33 and is connected to the bottom of the lifting plate 32. After the panel 6 completes the three-dimensional positioning correction, the L-shaped rod 36 is further flipped to apply pressure to the lifting plate 32, increasing the tension on the tension band 34. The first spring 342 is stretched, causing the lifting plate 32 to continue to descend, completing the contact between the probe 5 and the pin of the panel 6. If the first spring 342 is not set in the tension band 34, the tension band 34 cannot be stretched. After the first clamping block 24 and the second clamping block 25 simultaneously clamp the panel 6, the first clamping rod 22 cannot continue to move, and the lifting plate 32 cannot descend to the position where the probe 5 contacts the pin of the panel 6.

[0039] The elastic coefficient of the first spring 342 is greater than the elastic coefficient of the return spring. During the process of the tension band 34 pulling the first clamping rod 22 to move, the tension of the return spring on the second clamping rod 23 needs to be overcome. If the elastic coefficient of the first spring 342 is less than the elastic coefficient of the return spring, during the process of the tension band 34 pulling the first clamping rod 22, the first spring 342 may be stretched first, the overall length of the tension band 34 will be extended, the lifting plate 32 will be lowered, and the first clamping block 24 and the second clamping block 25 will remain in their initial position or the first clamping block 24 and the second clamping block 25 will not be clamped in place. Therefore, to prevent the first spring 342 from being stretched first, the elastic coefficient of the first spring 342 needs to be greater than the elastic coefficient of the return spring.

[0040] A specific application of the present invention is:

[0041] The panel 6 to be inspected is placed in the placement slot 11, and the operator flips the L-shaped rod 36 so that the pushing part 362 pushes the lifting plate 32 down. During the descent of the lifting plate 32, the tension belt 34 is pulled, and the lifting plate 32 causes the first clamping rod 22 to slide through the tension belt 34. The first clamping rod 22 drives the gear shaft 21 to rotate, and the gear shaft 21 in turn drives the two second clamping rods 23 to move. There is a gear transmission structure between the first clamping rod 22, the gear shaft 21, and the second clamping rod 23. Therefore, the first clamping rod 22 and the second clamping rod 23 move synchronously, thereby enabling the first clamping block 24 and the second clamping block 25 to clamp the panel 6 at the same time, thereby performing the function of simultaneous three-way positioning of the panel 6, so that the pins of the panel 6 are aligned with the probe 5.

[0042] After the pins of the panel 6 are aligned with the probe 5, continue to flip the L-shaped rod 36. Since the first clamping block 24 and the second clamping block 25 are now in contact with the side of the panel 6, the first clamping rod 22 and the second clamping rod 23 no longer move. Therefore, when the L-shaped rod 36 applies pressure to the tension belt 34, the first spring 342 is stretched, the overall length of the tension belt 34 is extended, and the lifting plate 32 continues to descend, so that the probe 5 installed at the bottom of the lifting plate 32 contacts the pins of the panel 6, thereby achieving signal conduction.

[0043] After the inspection is completed, the L-shaped rod 36 is flipped in the opposite direction. After the external force applied to the lifting plate 32 is removed, the telescopic spring pushes the lifting plate 32 to rise, and the reset spring pulls the two second clamping rods 23 to move in the opposite direction, causing the gear shaft 21 to rotate in the opposite direction, and then causing the first clamping rod 22 to slide in the opposite direction, so that the first clamping block 24 and the second clamping block 25 loosen the fixation on the panel 6.

[0044] During the lighting test, the up and down movement of the lifting plate can realize the clamping, positioning, fixing and loosening of the panel, which overcomes the problem of the prior art that each lighting test of a new panel requires repeated disassembly and assembly of the positioning fine-tuning block. The use of the fixture of the present invention can improve the convenience of the lighting test and the efficiency of panel detection. Moreover, the first clamping block and the second clamping block of the present invention first position the panel, and then the probe contacts the panel pin, which can also avoid the problem of poor contact of the probe pin caused by poor placement of the panel, thereby affecting the lighting result. At the same time, the L-shaped rod can be flipped by the operator, and there is no need to use a cylinder or other device to calibrate and clamp the panel, which saves costs while achieving the function.
