[0015] Compared with the prior art, the present invention has the following beneficial effects: it adopts a new structural design, and through the push rod and auxiliary plate, unqualified products can be quickly removed. At the same time, a toggle plate is provided to vibrate the buffer cloth, so that unqualified products can be quickly collected. In addition, an electrostatic brush plate capable of multi-directional cleaning is provided, which can efficiently clean the light collecting plate and improve work efficiency. The specific contents are as follows: During use of the automobile headlight optical testing equipment, the headlights to be tested are installed in the main clamping plate and the auxiliary clamping plate. After the headlights are turned on, the test is completed through the light collecting plate and the laser detector. When unqualified products are detected, the motor works, and the threaded rod and the column cooperate to make the main clamping plate and the auxiliary clamping plate drop synchronously, and then the push rod pushes the auxiliary plate, so that the auxiliary plate drives the auxiliary clamping plate to move in the direction of squeezing the first spring, and then the main clamping plate and the auxiliary clamping plate move away. At this time, the unqualified products fall onto the buffer cloth and are collected by the staff. In this process, the nozzle will spray marking liquid to mark the unqualified products, which is convenient for the staff to extract the unqualified products later and improves work efficiency.

[0016] Furthermore, when the main clamping plate descends, the airbag will be squeezed by the pressure plate, so that the airbag feeds the nozzle through the feeding pipe and the connecting pipe. At this time, the nozzle sprays the marking liquid. When the motor rotates and the main clamping plate rises, the airbag is not squeezed. At this time, the airbag expands again, which is convenient for the next use.

[0017] During operation, the automobile headlight optical testing equipment can place a collection box at the position of the lower connecting plate. When the main clamping plate descends, the main clamping plate drives the rack to descend. At this time, the rack and the gear cooperate to drive the rotating shaft and the toggle plate to rotate. Then the toggle plate pushes the buffer cloth, causing the headlights on the buffer cloth to slide down more quickly and enter the collection box, making it easier for staff to collect unqualified headlights.

[0018] Furthermore, the toggle plates are evenly spaced on the surface of the rotating shaft, which optimizes the effect of toggle buffer cloth unloading and improves work efficiency.

[0019] In this automobile headlight optical testing equipment, when the slider descends, the connecting shaft loses the tension of the traction rope. At this time, the connecting shaft rotates inside the testing table under the action of the torsion spring. At this time, the working block, the inner plate and the electrostatic brush plate rise in the vertical direction, and then the electrostatic brush plate can clean the surface of the light receiving plate, making the test results more accurate.

[0020] Furthermore, during the movement of the electrostatic brush plate, the external block will intermittently push the force-bearing block. At this time, the transition block will make reciprocating linear motion in the horizontal direction under the action of the thrust, guide rod and the second spring. Then the transition block will intermittently push the electrostatic brush plate, so that the electrostatic brush plate moves synchronously, which can not only clean the light-receiving plate in the vertical direction, but also in the horizontal direction, with high work efficiency.

[0021] Furthermore, when the electrostatic brush plate moves in the horizontal direction, the electrostatic brush plate will be driven by the guide groove and the guide rod to swing around the inner rod. At this time, the electrostatic brush plate is still in a reciprocating rotation state, so that the cleaning effect is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

The long pin 8 is movably connected to the auxiliary clamping plate 4, and a first spring 9 is fixedly connected between the auxiliary clamping plate 4 and the long plate 7, and the end of the long pin 8 is movably arranged inside the main clamping plate 3.

[0028] The lower surface of the auxiliary clamping plate 4 is fixedly connected to the auxiliary plate 13, and the lower surface of the auxiliary plate 13 is inclined, the upper surface of the detection platform 1 is fixedly connected to the push rod 14, the back of the main clamping plate 3 is fixedly connected to the pressure plate 22, the surface of the airbag 18 is fixedly connected to the feed pipe 19, and the feed pipe 19 is connected to the connecting pipe 20 through an external hose, and the side of the airbag 18 is fixedly connected to the feed pipe, and the surface of the feed pipe and the surface of the feed pipe 19 are both fixedly connected to a one-way valve.

[0029] During use, the headlights to be inspected are installed in the main clamping plate 3 and the auxiliary clamping plate 4. After turning on the headlights, the inspection is completed through the light receiving plate 29 and the laser detector 10. When unqualified products are detected, the motor 2 works. At this time, the threaded rod 12 and the column 5 cooperate to make the main clamping plate 3 and the auxiliary clamping plate 4 drop synchronously, and then the push rod 14 pushes the auxiliary plate 13, so that the auxiliary plate 13 drives the auxiliary clamping plate 4 to slide on the surface of the long pin 8 and move in the direction of squeezing the first spring 9, so that the main clamping plate 3 and the auxiliary clamping plate 4 move away from each other, and the unqualified products fall onto the buffer cloth 16. It is collected by the staff, and when the main clamping plate 3 descends, the airbag 18 will be squeezed by the pressure plate 22, so that the airbag 18 feeds the nozzle 21 through the feeding pipe 19 and the connecting pipe 20. At this time, the nozzle 21 sprays the marking liquid, and when the motor 2 rotates and the main clamping plate 3 rises, the airbag 18 is not squeezed. At this time, the airbag 18 expands again, which is convenient for the next use. After long-term use, the marking liquid is replenished to the airbag 18 through the feeding pipe. At the same time, during the working process of the airbag 18, the one-way valve makes the flow direction of the marking liquid from the airbag 18 to the nozzle 21, and the marking liquid will not flow back.

[0030] Embodiment 2: The difference from embodiment 1 is that the material on the buffer cloth 16 is quickly dropped by setting the toggle plate 27. Figure 5 and Figure 6 As shown, the lower surface of the detection platform 1 is fixedly connected to the lower plate 15, and the surface of the lower plate 15 is fixedly connected to the buffer cloth 16, and the lower surface of the detection platform 1 is connected to the toggle plate 27 through a reciprocating mechanism; the reciprocating mechanism includes a working plate 23 fixedly connected to the lower surface of the detection platform 1, and the working plate 23 is internally provided with a rotating shaft 24, and the surface of the rotating shaft 24 is fixedly connected to a gear 25, the lower surface of the main clamping plate 3 is fixedly connected to a rack 26 meshing with the gear 25, and the toggle plates 27 are distributed at equal angles on the surface of the rotating shaft 24.

[0031] During operation, a collection box can be placed at the position of the lower connecting plate 15, and when the main clamping plate 3 descends, the main clamping plate 3 drives the rack 26 to descend. At this time, the rack 26 and the gear 25 cooperate to drive the rotating shaft 24 and the toggle plate 27 to rotate, and then the toggle plate 27 will push the buffer cloth 16, so that the car lights on the buffer cloth 16 slide down more quickly and enter the collection box, making it easier for the staff to collect the car lights. At the same time, the toggle plates 27 are evenly spaced on the surface of the rotating shaft 24, which optimizes the effect of toggling the buffer cloth 16 to cut materials and improves work efficiency.

[0032] Embodiment 3: Different from embodiment 2, the surface of the light receiving plate 29 can be quickly cleaned by providing the inner plate 34 and the electrostatic brush plate 35. Figure 7-Figure 9As shown, a connecting shaft 32 is provided for internal rotation of the detection platform 1, and the upper surface of the detection platform 1 is fixedly connected to the limiting column 30, the lower surface of the slider 6 is fixedly connected to the traction rope 28, and the other side of the traction rope 28 is wrapped and fixedly connected to the surface of the connecting shaft 32, and the surface of the connecting shaft 32 and the surface of the limiting column 30 are both movably connected to the working block 33.

[0033] The connecting shaft 32 is threadedly connected to the working block 33, and the swing mechanism includes a guide rod 39 fixedly connected to the inner wall of the inner plate 34, and a transition block 41 is movably provided inside the inner plate 34, and the surface of the transition block 41 is fixedly connected to the force block 38, and the raised position on the surface of the transition block 41 is penetrated by the guide rod 39, the surface of the connecting shaft 32 is fixedly connected to the torsion spring 36, and the other side of the torsion spring 36 is fixedly connected to the inner wall of the detection platform 1, and the torsion spring 36 is initially in a stretched state, the upper surface of the detection platform 1 is fixedly connected to the vertical plate 31, and the surface of the vertical plate 31 is fixedly connected to the external block 37, and the surface of the force block 38 and the surface of the force block 38 are both arc structures.

[0034] When the slider 6 descends, the connecting shaft 32 loses the tension of the traction rope 28. At this time, the connecting shaft 32 rotates inside the detection table 1 under the action of the torsion spring 36. At this time, the working block 33, the inner plate 34 and the electrostatic brush plate 35 rise in the vertical direction, and then the electrostatic brush plate 35 can clean the surface of the light receiving plate 29, making the detection result more accurate. When the slider 6 rises again, the slider 6 drives the connecting shaft 32 to rotate through the traction rope 28. At this time, the connecting shaft 32 will release the traction rope 28, and at the same time, the torsion spring 36 will be stretched again to facilitate the next use.

[0035] Embodiment 4: Different from embodiment 3, the external block 37 and the force block 38 are provided, so that the electrostatic brush plate 35 can make a reciprocating linear motion in the horizontal direction, thereby optimizing the cleaning effect.

[0036] During the movement of the electrostatic brush plate 35, the external block 37 will intermittently push the force-bearing block 38. At this time, the transition block 41 will make reciprocating linear motion in the horizontal direction under the action of the thrust, the guide rod 39 and the second spring 40. Then the transition block 41 will intermittently push the electrostatic brush plate 35, so that the electrostatic brush plate 35 moves synchronously. The electrostatic brush plate 35 can not only clean the light-receiving plate 29 in the vertical direction, but also clean the light-receiving plate 29 in the horizontal direction, with high working efficiency. At the same time, when the electrostatic brush plate 35 moves in the horizontal direction, the electrostatic brush plate 35 will be driven by the guide groove 43 and the guide rod 44, and swing around the inner rod 42. At this time, the electrostatic brush plate 35 is still in a reciprocating rotation state, so that the cleaning effect is further improved.
