One side of the upper end of the support frame 4 is fixedly connected to a motor 5 31, and the output end of the motor 5 31 is fixedly connected to one end of the threaded rod 4 30. One side of the upper end surface of the transverse plate 35 is fixedly connected to an electric push rod 4 33, and the piston end of the electric push rod 4 33 is fixedly connected to the guide plate 32.

[0052] Specifically, the existing automatic inspection device for appearance defects of automobile headlights utilizes a CCD inspection camera 36 to inspect the headlights, and removes the inspected headlights by a robot or manually. However, usually, the headlights that pass or fail the appearance quality inspection need to be transferred to different processes for subsequent processing. After the headlights are removed by a robot or manually, the qualified and unqualified headlights may be piled together, which is not conducive to subsequent transportation.

[0053] Therefore, in order to avoid the above problems, when the present embodiment is used, after the detection of a headlight is completed, the headlight after the detection will continue to follow the conveyor belt 2 to move to the bottom of the guide plate 32, and according to the detection result of the headlight, the motor 5 31 can be used to drive the threaded rod 4 30 to rotate, so that the guide plate 32 is on one side of the headlight, and the electric push rod 4 33 is used to drive the guide plate 32 to descend, and then the guide plate 32 is driven to move horizontally, so that the headlight is aligned with the placement plate 5 on the left or right side. When the headlight moves to the end of the conveyor belt 2, it can slide onto the placement plate 5 under the action of gravity, and then repeat the above operation, so that multiple headlights can be placed on the placement plate 5 in an arranged manner, so that the headlights that pass and fail the detection are placed separately, which is more convenient for subsequent processing. When the headlight on the placement plate 5 needs to be removed, the motor 6 37 can be used to drive the threaded rod 7 27 to rotate, so that the adjustment frame 41 is away from the conveyor belt 2, and then the motor 9 48 is used to drive the placement plate 5 to rotate, so that the headlight on the placement plate 5 can slide off, and then the slipped headlight can be collected;

[0054] Since the headlights slide onto the placement plate 5 under the action of gravity, adjacent headlights will collide with each other, and when a large number of headlights accumulate, some headlights will be squeezed with greater force, which may easily lead to damage to the headlights. In addition, in some cases, due to the different transfer tools, the number of headlights that can be carried is limited. When the headlights slide from the end of the placement plate 5, if the number of headlights on the placement plate 5 exceeds the number of headlights that the transfer tool can bear, the transfer work cannot be carried out normally. Therefore, in order to avoid the above problems, every time a headlight slides onto the placement plate 5, the motor 4 23 will drive the threaded rod 21 to rotate, so that the push rod 6 moves. When the push rod 6 moves, it will squeeze the baffle 18 to make it slide to the other side of the fixed plate 19 to block the sliding headlight, and, Since the contact surface between the baffle 18 and the headlight is made of elastic material, the baffle 18 can buffer the headlight and will not cause damage to the headlight. Since multiple baffles 18 are provided and the push rod 6 has a certain length, as the number of headlights on the placement plate 5 increases, the push rod 6 is constantly moving to make multiple baffles 18 block the headlights, so that multiple headlights can be placed separately, avoiding damage to the headlights due to mutual collision and squeezing of the headlights; and when the headlight slides off the end of the placement plate 5, the push rod 6 can be driven to move to move the push rod 6 away from the baffle 18, and the baffle 18 is reset under the action of the spring 42, and the falling amount of the headlight can be controlled by controlling the number of baffles 18 reset to adapt to different transport tools and ensure the normal progress of the transport work;

[0055] Moreover, in some cases, when qualified headlights and unqualified headlights are placed on the placement plates 5 on both sides, workers are required to make further judgments on the unqualified headlights. If the problems can be solved by repair or rework, these headlights need to be selected separately and transported to the repair or rework area for processing; and for qualified headlights, in some cases, even if the qualified headlights are the same, there may still be slight differences between them, so some representative headlights need to be manually selected and further tested or developed. When the headlights to be selected are among multiple headlights, the remaining headlights need to be slid off the placement plate 5 before they can be taken out separately, which affects the placement and transportation of the remaining headlights and is more troublesome. Therefore, in order to solve this problem, according to the number of headlights to be selected separately and the position of the headlights, the motor 7 40 is used to drive the threaded rod 6 39 to rotate so that the partition 4 6 slides downward until its upper end is flush with the upper end of the placement plate 5. At this time, the motor 3 20 can drive the threaded rod 5 38 to rotate, so that the adjustment plate 13 moves horizontally, and the push rod 16 is aligned with the through hole 17 at different positions. At this time, the electric push rod 2 14 is used to drive the push rod 16 to pass through the through hole 17, so that the lamp at the corresponding position can be pushed onto the unloading frame 47, and then the unloading frame 47 can be driven to tilt to make the selected lamp slide from the end of the unloading frame 47, thereby realizing the separate collection of the selected lamps, and then facilitating the transfer of the repairable lamps among the unqualified lamps to the repair or rework area for processing. At the same time, it is also convenient for further testing or research and development of some representative qualified lamps, avoiding the situation that when the lamp to be selected is between multiple lamps, the remaining lamps need to slide off the placement plate 5 before they can be taken out separately, ensuring the normal placement and transfer of the remaining lamps, which is more convenient.

[0056] When the car light slides on the placement plate 5 and the blanking frame 47, the car light may be stuck somewhere due to friction, thereby affecting normal loading and unloading. Therefore, in order to avoid this situation, when the car light slides under the action of gravity, the electric push rod 18 can be used to drive the push plate 25 to move, and the motor 2 12 can be used to drive the threaded rod 3 24 to rotate, so that the push plate 25 moves horizontally, so that the push plate 25 is at the blanking frame 47 or the placement plate 5, and then the motor 11 drives the threaded rod 10 to rotate to move the push plate 25 back and forth to push the stuck car light so that it can slide smoothly, thereby avoiding the situation that the car light is stuck somewhere due to friction when it slides on the placement plate 5 and the blanking frame 47, and ensuring the normal sliding of the car light.

[0057] Working principle: according to the size of the headlights to be visually inspected, the motor 8 43 is used to drive the bidirectional threaded rod 44 to rotate to adjust the spacing between the two limit plates 45, and the narrowest spacing between the two limit plates 45 can only allow the headlights to pass in an arranged manner, but not side by side. Then, multiple headlights to be visually inspected are placed at the rear end of the conveyor belt 2, and do not need to be neatly arranged. When the conveyor belt 2 is running, the limit plates 45 will cause the multiple headlights to be arranged at the narrowest spacing between the two limit plates 45, and each time a headlight moves under the CCD inspection camera 36, ​​the CCD inspection camera 36 will inspect its appearance quality, so that the headlights can be arranged in an orderly manner under the action of the two limit plates 45, ensuring that each headlight can pass through the CCD inspection camera 36 in a fixed position. The CCD inspection camera 36 can capture the complete image of each headlight one by one, reducing the inspection error caused by improper position of the headlights, and also eliminating the need to manually arrange the headlights neatly on the conveyor belt 2. The above process is relatively labor-saving. When the detection of a headlight is completed, the headlight after the detection will continue to follow the conveyor belt 2 to move under the guide plate 32, and according to the detection result of the headlight, the motor 5 31 can be used to drive the threaded rod 4 30 to rotate, so that the guide plate 32 is on one side of the headlight, and the electric push rod 4 33 is used to drive the guide plate 32 to descend, and then the guide plate 32 is driven to move horizontally, so that the headlight is aligned with the placement plate 5 on the left or right side. When the headlight moves to the end of the conveyor belt 2, it can slide onto the placement plate 5 under the action of gravity, and then repeat the above operation, so that multiple headlights can be placed on the placement plate 5 in an arranged manner, so that the headlights that pass and fail the detection are placed separately, which is more convenient for subsequent processing. When the headlight on the placement plate 5 needs to be removed, the motor 6 37 can be used to drive the threaded rod 7 27 to rotate, so that the adjustment frame 41 is away from the conveyor belt 2, and then the motor 9 48 is used to drive the placement plate 5 to rotate, so that the headlight on the placement plate 5 can slide off, and then the fallen headlights can be collected;Because the headlights slide onto the placement plate 5 under the action of gravity, adjacent headlights will collide with each other, and when a large number of headlights accumulate, some headlights will be squeezed with greater force, which may easily lead to damage to the headlights. In addition, in some cases, due to the different transfer tools, the number of headlights that can be accommodated is limited. When the headlights slide from the end of the placement plate 5, if the number of headlights on the placement plate 5 exceeds the number of headlights that the transfer tool can bear, the transfer work cannot be carried out normally. Therefore, in order to avoid the above problems, every time a headlight slides onto the placement plate 5, the motor 4 23 will drive the threaded rod 21 to rotate, so that the push rod 6 moves. When the push rod 6 moves, it will squeeze the baffle 18 to make it slide to the other side of the fixed plate 19 to block the sliding headlight. In addition, because the contact surface between the baffle 18 and the headlight is made of elastic material, the baffle 18 can have a buffering effect on the headlight and will not cause damage to the headlight. If there are multiple lights on the placement plate 5 and the push rod 6 has a certain length, as the number of lights on the placement plate 5 increases, the push rod 6 is constantly moving to make multiple baffles 18 block the lights, so that the multiple lights can be placed separately, avoiding the damage of the lights due to mutual collision and extrusion of the lights; and when the lights slide off the end of the placement plate 5, the push rod 6 can be driven to move to make the push rod 6 away from the baffle 18, and the baffle 18 is reset under the action of the spring 42, and the falling amount of the lights can be controlled by controlling the number of resets of the baffle 18 to adapt to different transport tools and ensure the normal progress of the transport work; and in some cases, when qualified lights and unqualified lights are placed on the placement plates 5 on both sides, for the unqualified lights, workers need to make further judgments on them. If the problem can be solved by repair or rework, these lights need to be selected separately and transported to the repair or rework area for processing;As for qualified headlights, in some cases, even if the qualified headlights are the same, there may still be slight differences between them. In this case, some representative headlights need to be manually selected for further testing or research and development. When the headlight to be selected is among multiple headlights, the remaining headlights need to be slid off the placement plate 5 before they can be taken out separately, which affects the placement and transportation of the remaining headlights and is quite troublesome. Therefore, in order to solve this problem, according to the number of headlights to be selected separately and the position of the headlights, the motor 740 is used to The threaded rod 6 39 is driven to rotate, so that the partition 46 slides downward until its upper end is flush with the upper end of the placement plate 5. At this time, the threaded rod 5 38 can be driven to rotate by the motor 3 20 to make the adjustment plate 13 move horizontally, so that the push rod 16 is aligned with the through holes 17 at different positions. At this time, the push rod 2 14 is used to drive the push rod 16 to pass through the through hole 17, so that the headlights at the corresponding positions can be pushed onto the blanking frame 47, and then the blanking frame 47 can be driven to tilt to make the selected headlights slide from the end of the blanking frame 47, thereby realizing the separate collection of the selected headlights, and then facilitating the collection of the unselected headlights. Among the qualified lamps, the lamps that can be repaired are transferred to the repair or rework area for processing. At the same time, it is also convenient to further test or develop some representative qualified lamps, avoiding the situation that when the lamp to be selected is located between multiple lamps, the remaining lamps need to slide off the placement plate 5 before they can be taken out separately, ensuring the normal placement and transportation of the remaining lamps, which is more convenient; when the lamp slides on the placement plate 5 and the blanking frame 47, due to friction, the lamp may be stuck somewhere, thereby affecting normal loading and unloading, so for To avoid this situation, when the headlight slides under the action of gravity, the electric push rod 18 can be used to drive the push plate 25 to move, and the motor 2 12 can be used to drive the threaded rod 3 24 to rotate, so that the push plate 25 moves horizontally, so that the push plate 25 is at the unloading frame 47 or the placement plate 5, and then the motor 11 drives the threaded rod 10 to rotate, so that the push plate 25 moves forward and backward to push the stuck headlight so that it can slide smoothly, thereby avoiding the situation where the headlight is stuck somewhere due to friction when the headlight slides on the placement plate 5 and the unloading frame 47, and ensuring the normal sliding of the headlight. ;
