Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 8As shown, the present invention provides an auxiliary device for rapid quality inspection of LED surface light sources, comprising a workbench 1, a long slide groove 11 is opened on the top of the workbench 1, a U-shaped plate 12 for placing an LED lamp board is slidably connected to the outer wall of the top of the workbench 1, and double ball bar grooves are opened on both ends and one side of the U-shaped plate 12, and a rectangular slider 13 is fixedly connected to the outer wall of the bottom end of the U-shaped plate 12, and the rectangular slider 13 and the inner wall of the long slide groove 11 can be intermittently fitted and slidably connected, and also includes: a quality inspection part 2, the quality inspection part 2 includes a motor 22, a screw rod 23 is fixedly connected to one end of the motor 22, a hollow slide plate 25 is threadedly connected to the screw rod 23, and a guide rod 24 is also slidably connected to the hollow slide plate 25, and a support plate 27 that can indirectly drive it to move and a test pen 28 fixedly connected to the outer walls on both sides of the bottom end of the support plate 27 are provided below the hollow slide plate 25, and the two passively moving test pens 28 can perform quality inspection on the LED lamp beads.

[0032] The above scheme is adopted: by starting the motor 22 on the U-shaped bracket 21 to drive the screw 23 to rotate, thereby driving the hollow skateboard 25 to move, and the movement process will be guided by the connected guide rod 24, and then the horizontal movement of the hollow skateboard 25 will synchronously drive the arc long plate 26 to translate, and the arc long plate 26 moving downward on the hollow skateboard 25 will synchronously drive the support plate 27 and the test pen 28 installed on both sides of the bottom of the support plate 27 to move downward, when the two test pens 28 are passively moved downward, they can contact the corresponding positive and negative poles on each LED lamp bead, thereby performing quality inspection of the LED lamp bead, and then through this device, it can be avoided that the manual hand-held test pen 28 is used to perform quality inspection on the LED lamp beads one by one.

[0033] The quality inspection part 2 specifically also includes a U-shaped bracket 21 fixedly connected to the outer walls at both ends of the workbench 1, the outer wall of one end of the U-shaped bracket 21 is fixedly connected to the outer wall of one end of the motor 22, the two ends of the screw 23 are respectively rotatably connected to the two ends of the U-shaped bracket 21, and the two ends of the guide rod 24 are fixedly connected to the inner walls at both ends of the U-shaped bracket 21, and a circular arc long plate 26 is slidably connected through one end of the hollow slide plate 25, and the bottom end of the circular arc long plate 26 is fixedly connected to the top outer wall of the support plate 27, and springs 29 are jointly fixedly connected between the outer walls on both sides of the bottom end of the hollow slide plate 25 and the outer walls on both sides of the top end of the support plate 27, and a guardrail frame 230 is also fixedly connected to the inner walls at both ends of the U-shaped bracket 21, and a plurality of triangular oblique blocks 231 are fixedly connected to the outer wall of the bottom end of the guardrail frame 230, and the outer wall of one end of each triangular oblique block 231 can be intermittently fitted and slidably connected with the top outer wall of the circular arc long plate 26.

[0034] The above scheme is adopted: when the arc long plate 26 contacts the triangular inclined block 231 installed on the guardrail frame 230, the arc long plate 26 that passively and continuously moves will exert pressure on the inclined surface of the triangular inclined block 231 when it contacts the inclined surface, causing it to gradually move downward along the inclined surface. When the support plate 27 moves downward, it will pull the two springs 29 to cause them to deform. Through the two springs 29, when the arc long plate 26 is no longer pressed by external force, the arc long plate 26 can be driven to reset.

[0035] A toothed plate 232 is fixedly connected to the side wall of one end of the support plate 27, and a spur gear 233 can be intermittently meshed on the toothed plate 232. A cam 234 is fixedly connected to the outer wall of the top of the spur gear 233. A U-shaped rod 235 is movably sleeved on the cam 234 and the spur gear 233. Both ends of the U-shaped rod 235 are fixedly connected to the inner wall of one end of the U-shaped bracket 21. The outer wall of one end of the cam 234 can be intermittently fitted and slidably connected with a bent convex plate 236. The bent convex plate 236 is specifically composed of two plates of different materials, one smooth plate is made of metal, and the other plate with a convex surface is made of natural The bending convex plate 236 is made of rubber, and a T-shaped slider 237 is fixedly connected to the outer wall of one end of the bending convex plate 236, and a limiting slot plate 238 is also fixedly connected to the inner wall of one end of the U-shaped bracket 21. A T-shaped slot 239 that can be slidably engaged with the T-shaped slider 237 is provided on one end of the limiting slot plate 238. A locking ball 240 is fixedly connected to the outer walls of both ends of the bending convex plate 236, and ball grooves 241 that can be intermittently and tightly engaged with the two locking balls 240 are provided on both ends of the limiting slot plate 238. Two elastic parts are also fixedly connected between the outer wall of one end of the bending convex plate 236 and the inner wall of one end of the limiting slot plate 238.

[0036] By adopting the above scheme, when the hollow slide plate 25 moves forward to a certain distance on the screw rod 23, it will drive the tooth plate 232 on the support plate 27 to contact and mesh with the spur gear 233, causing it to rotate. The rotating spur gear 233 will synchronously drive the cam 234 to rotate on the U-shaped rod 235, so that the rotating cam 234 will hit and push the bent convex plate 236, so that the bent convex plate 236 drives the U-shaped plate 12 that is attached and connected to slide in a limited manner in the elongated slide groove 11 through the rectangular slider 13, thereby enabling the measuring The test pen 28 is placed against another group of untested lamp beads on the LED lamp board. When the bending convex plate 236 is pushed, the card ball 240 on one end will be driven to disengage from the corresponding card-engaged ball groove 241, and then guided to slide in the T-shaped slide groove 239 in the limit groove plate 238 through the installed T-shaped slider 237. Once the bending convex plate 236 without limit engagement is driven to slide by the two elastic parts, until the card ball 240 installed on the other end of the bending convex plate 236 is engaged in the corresponding ball groove 241 for limiting.

[0037] A sleeve rod 242 is specifically fixedly connected to the outer wall of one end of the support plate 27, and a screw rod 243 is threadedly connected to the inner wall of one side of the sleeve rod 242. A rectangular plate is movably sleeved on the outer wall of one end of the screw rod 243, and the outer wall of one end of the rectangular plate and the U-shaped bracket 21 are fixedly connected. A synchronous belt 244 is also fixedly connected to the screw rod 243, and a rotating rod 245 is also fixedly connected to one side of the synchronous belt 244. One side of the rotating rod 245 can be intermittently slidably engaged with a double ball rod groove opened on one side of the U-shaped plate 12.

[0038] The above scheme is adopted: through the reciprocating quality inspection of forward and reverse movement, the support plate 27 will also synchronously drive the sleeve rod 242 to translate, thereby the screw rod 243 in the sleeve rod 242 will be driven to rotate, and then the rotating rod 245 will be synchronously driven to rotate through the synchronous belt 244. The rotating rotating rod 245 can drive the U-shaped plate 12 to tilt at a fixed point on the workbench 1. The U-shaped plate 12 in the tilted state does not affect the placement of the LED lamp bead board, and it can also facilitate the subsequent unloading of the LED lamp bead board on the U-shaped plate 12.

[0039] One point that needs to be explained is that the motor 22 is specifically a power source of a forward and reverse rotation type, and the rotation of the screw 23 is interrupted, specifically when the arc long plate 26 passes through the lowest end of the triangular inclined block 231, there will be a two-second pause time, and if the LED lamp beads being tested have quality problems and cannot light up, they need to be marked manually with a marker for easy identification. In addition, placing the LED lamp bead panel on the U-shaped plate 12 also requires manual operation. The friction between the rotating rod 245 and the double ball rod groove is sufficient to drive the U-shaped plate 12 to tilt.

[0040] The working principle and use process of the present invention are as follows: by starting the motor 22 on the U-shaped bracket 21 to drive the screw 23 to rotate, the hollow slide 25 is driven to move, and the movement process is guided by the connected guide rod 24, and then the horizontal movement of the hollow slide 25 will synchronously drive the arc long plate 26 to translate, until the arc long plate 26 contacts the triangular inclined block 231 installed on the fence frame 230, and the passive and continuously translated arc long plate 26 will press against the inclined surface of the triangular inclined block 231 when it contacts it, so that it gradually moves down along the inclined surface, and moves down on the hollow slide 25. The moving arc long plate 26 will synchronously drive the support plate 27 and the test pen 28 installed on both sides of the bottom of the support plate 27 to move downward. When the support plate 27 moves downward, it will pull the two springs 29 to deform them. The two springs 29 can drive the arc long plate 26 to reset when the arc long plate 26 is no longer pressed by external force. When the two test pens 28 are passively moved downward, they can contact the corresponding positive and negative poles on each LED lamp bead, thereby performing quality inspection of the LED lamp bead. Furthermore, this device can avoid manually holding the test pen 28 to perform quality inspection on the LED lamp beads one by one, thereby reducing manual labor.

[0041] At the same time, when the hollow slide plate 25 moves forward to a certain distance on the screw rod 23, it will drive the tooth plate 232 on the support plate 27 to contact and mesh with the spur gear 233, causing it to rotate. The rotating spur gear 233 will synchronously drive the cam 234 to rotate on the U-shaped rod 235, so that the rotating cam 234 will hit and push the bent convex plate 236, so that the bent convex plate 236 drives the U-shaped plate 12 that is fitted and connected to slide in a limited manner in the long slide groove 11 through the rectangular slider 13, thereby enabling the test pen 28 to face another group of undetected lamp beads on the LED lamp board. When the bent convex plate 236 is pushed, it will drive the card ball on one end 240 is separated from the corresponding ball groove 241, and then the T-shaped slide block 237 is installed to guide and slide in the T-shaped slide groove 239 in the limit groove plate 238, and once the bent convex plate 236 without limit clamping is driven to slide by the two elastic members, until the clamping ball 240 installed on the other end of the bent convex plate 236 is clamped into the corresponding ball groove 241 for limit, thereby indirectly driving the two test pens 28 to move synchronously through the reverse rotation of the motor 22, another group of quality inspections can be performed on the LED lamp beads placed in the U-shaped plate 12 after translation, which greatly reduces the manual operation links and effectively improves the quality inspection efficiency;

[0042] Finally, through the forward and reverse reciprocating quality inspection, the support plate 27 will synchronously drive the sleeve rod 242 to translate, thereby the screw rod 243 in the sleeve rod 242 will be driven to rotate, and then the rotating rod 245 will be synchronously driven to rotate through the synchronous belt 244. The rotating rotating rod 245 can drive the U-shaped plate 12 to tilt at a fixed point on the workbench 1. The tilted U-shaped plate 12 does not affect the placement of the LED lamp bead board, and it is also convenient for the subsequent unloading of the LED lamp bead board on the U-shaped plate 12, so that it can slide automatically.
