[0002] The inspection items of automobile lights mainly include the following aspects: the intensity and beam direction of automobile lights must comply with national and regional regulatory standards to ensure sufficient lighting when driving at night without causing blind spots or interfering with other vehicle drivers. Different types of lights such as car headlights, clearance lights, brake lights, turn signals, etc. must emit the correct color to comply with traffic regulations and safety requirements. The reflection effect of reflective lights such as reflectors and tail lights must meet the prescribed standards to ensure that other vehicles can see them clearly under low light conditions. Appearance inspection ensures that the appearance of the lights meets the design standards and facilitates the installation, removal and fixation of the lights.

[0003] However, there is currently a lack of a more professional testing process for car lights. The first is the appearance inspection of the car.

[0015] Working principle: First, the staff puts the headlight to be tested on the placement table, then starts the fourth motor, drives the spur gear to rotate through the fourth motor, and uses the meshing transmission of the spur gear and the rack plates on both sides to drive the two clamps to move inward at the same time, thereby clamping the headlight and improving the stability of subsequent measurements. Then, the shape of the headlight is entered through the control panel to preset the movement trajectory of the middle tube and the resistance ball. In the final detection process, the resistance ball will always keep in contact with the surface of the headlight, and then start the first motor, drive the first worm to rotate through the first motor, and drive the first worm wheel and The first rotating rod rotates, thereby driving the rotating shaft to rotate. When the rotating shaft rotates, it will drive the first pulleys on both sides to rotate, and through the transmission of the first synchronous belt, all the first pulleys are driven to rotate, and the movement of the rotating first pulley on the first light rod is used to drive the interference ball in the middle mechanism to move back and forth, and then the second motor is started. Similarly, the second motor drives the second worm to rotate, driving the second worm wheel and the second rotating rod on one side to rotate, and then through the transmission of the second transmission wheel and the second synchronous belt, the two second rotating rods and the four second pulleys are rotated synchronously, and the movement of the rotating second pulley on the second light rod is used to drive the The third motor is finally started to drive the third worm to rotate, which drives the third worm wheel to rotate. The third worm wheel will drive the winding wheel to rotate, and the rotating winding wheel will release and retract the pull rope, so that the middle tube and the friction ball will rise and fall. The friction ball will be installed with a preset trajectory to fit the surface of the car light and move, so the position of the movable block in the middle tube will always remain unchanged. When there is an unqualified position in the shape of the car light, the friction ball will drive the movable block to rise or fall, and the movable block will drive the metal ring to rise and fall. At this time, the first electromagnetic coil is connected with a cross Variable current, since the energized coil will generate a magnetic field, and when the magnetic flux of the closed coil in the magnetic field changes, an induced current will be generated. When an alternating current is passed through the first electromagnetic coil, an alternating magnetic field will be generated, and an alternating induced current will be generated in the second electromagnetic coil. During the lifting process, a part of the metal ring will enter between the first electromagnetic coil and the second electromagnetic coil. The intervention of the metal ring will produce a resistance effect on the magnetic field created by the first electromagnetic coil, thereby reducing the current generated by the second electromagnetic coil, thereby judging the specific location and degree of unqualified appearance of the car light, and improving the detection effect.

[0016] When conducting light intensity detection, the car lights are powered on to make the light shine on the photoresistor board. The brightness of the car lights is sensed by the photoresistor board and converted into electrical signals for further processing and recording of light intensity data. At the same time, the coordinated extension and retraction of six electric cylinders realizes six degrees of freedom, including translation along the X, Y, and Z directions and rotation around the X, Y, and Z axes, as well as the compound movement of these degrees of freedom, to drive the placement table and the clamp to shake the car lights at multiple angles and directions, simulating various road conditions that the car may encounter during driving, and then observing the changes in light intensity data captured by the photoresistor board, thereby improving the accuracy of the car lights in light intensity detection.

[0017] When testing reflective lamps such as rearview reflective lamps, turn on the laser transmitter, which emits a pulsed laser beam to illuminate the reflective lamp. The electric telescopic rod drives the mounting frame to swing, which changes the irradiation position of the laser beam. The lifting cylinder controls the lifting of the placement table and the headlight to reflect the laser beam onto the receiver. The change in laser intensity received by the receiver is observed to determine the reflective performance evaluation of the reflective lamp. In addition, the fill light can be turned on to observe the reflective performance of the reflective lamp under different ambient light intensities.

[0018] The present invention provides a vehicle lamp detection device, which has the following beneficial effects:

[0019] 1. The present invention clamps and fixes the headlight on a placement table, uses a control panel to preset the movement trajectory of the interference ball, and then controls the interference ball to move along the preset trajectory. Through the size of the induced current generated by the second electromagnetic coil, it can be determined whether the headlight has defects in appearance, the location of the defects, and the size of the defects, thereby improving the detection effect.

[0020] 2. The present invention realizes six degrees of freedom of movement, including translation along the X, Y, and Z directions and rotation around the X, Y, and Z axes, through the coordinated extension and retraction of six electric cylinders, as well as the compound movement of these degrees of freedom, to drive the placement table and the clamp to shake the headlights at multiple angles and directions, simulating various road conditions that a car may encounter during driving, and then observing the changes in light intensity data captured by the photoresistor board, thereby improving the accuracy of the headlights in light intensity detection.

When the third worm wheel 25 rotates, it will drive the winding wheel 26 to rotate. A guide wheel 27 is movably installed on one side of the middle part of the second mounting plate 15, and a pull rope 28 is wound on the outer diameter of the winding wheel 26.

[0035] Specifically, first, the staff puts the headlight to be tested on the placement table 41, and then starts the fourth motor 45. The spur gear 46 is driven to rotate by the fourth motor 45, and the two clamping plates 43 are driven to move inward at the same time by the meshing transmission of the spur gear 46 and the rack plates 44 on both sides, so as to clamp the headlight and improve the stability of subsequent measurements.

In the final detection process, the interference ball 31 will always maintain contact with the surface of the headlight.

[0036] In this embodiment, the inner bottom of the base 1 is fixedly connected to a base 35, and a chassis 36 is installed in the middle of the bottom wall of the base 35 through a lifting cylinder 37.

[0037] Furthermore, two first rotating rods 13 are movably connected inside the first mounting plate 5. The first rotating rods 13 pass through both ends of the first mounting plate 5. The middle part is connected to the first mounting plate 5 by a bearing seat. The outer ends of the first rotating rods 13 are fixedly connected to the first transmission wheels 6. The outer diameters of the first transmission wheels 6 on the corresponding sides are connected by the first synchronous belt 7.

[0038] Furthermore, a first motor 9 is fixedly installed on the upper side of the inner end of the first mounting plate 5, and a first worm 10 is fixedly connected to the driving end of the first motor 9. The inner ends of the front first rotating rod 13 are respectively fixedly connected to the two ends of the rotating shaft 11, and a first worm wheel 12 is fixedly connected to the outer diameter of one side of the rotating shaft 11. The bottom end of the first worm 10 is meshedly connected to the bottom of the first worm wheel 12. The first worm 10 is driven to rotate by the first motor 9, which drives the first worm wheel 12 and the rotating shaft 11 to rotate.

[0039] Specifically, start the first motor 9, and drive the first worm 10 to rotate through the first motor 9, thereby driving the first worm wheel 12, the rotating shaft 11 and the first rotating rod 13 to rotate. When the rotating shaft 11 rotates, it will drive the first pulley 8 and the first transmission wheel 6 on both sides to rotate. Through the transmission of the first synchronous belt 7, all the first pulleys 8 are driven to rotate. The movement of the rotating first pulley 8 on the first light rod 4 is utilized to drive the middle mechanism to move forward and backward, so as to facilitate subsequent detection work.

[0040] Furthermore, two second rotating rods 16 are movably connected to the inner upper side of the second mounting plate 15. The second rotating rods 16 pass through both sides of the second mounting plate 15 and are connected to the inside thereof through bearing seats. Second pulleys 17 are fixedly connected to both ends of the second rotating rod 16, and the bottoms of the second pulleys 17 on the corresponding sides are movably connected to the outer diameter of the second light rod 14. When the second pulley 17 rotates, it will drive all structures to move left and right along the second light rod 14, so as to facilitate the adjustment of the position of the bottom structure. A second transmission wheel 18 is fixedly connected to the middle outer diameter of the second rotating rod 16, and the outer diameters of the second transmission wheels 18 are connected by a second synchronous belt 19.

[0042] Specifically, the second motor 20 is started, and the second worm 21 is driven to rotate by the second motor 20, thereby driving the second worm wheel 22 and the second rotating rod 16 on one side to rotate, and then the two second rotating rods 16 and the four second pulleys 17 are rotated synchronously through the transmission of the second transmission wheel 18 and the second synchronous belt 19. The movement of the rotating second pulley 17 on the second light rod 14 is used to drive the bottom structure to move left and right, so that the middle cylinder 29 follows the movement.

[0044] Specifically, the third motor 23 drives the third worm 24 to rotate, which drives the third worm wheel 25 to rotate. When the third worm wheel 25 rotates, it drives the winding wheel 26 to rotate.

The resistance ball 31 is installed with a preset trajectory and moves on the surface of the car lamp. Therefore, the position of the movable block 30 in the middle cylinder 29 will always remain unchanged. When there is an unqualified position in the shape of the car lamp, the resistance ball 31 will drive the movable block 30 to rise or fall, and the movable block 30 will drive the metal ring 32 to rise and fall. At this time, an alternating current is introduced into the first electromagnetic coil 33. Current, since an energized coil will generate a magnetic field, and when the magnetic flux of a closed coil in the magnetic field changes, an induced current will be generated. When an alternating current is passed through the first electromagnetic coil 33, an alternating magnetic field will be generated, and an alternating induced current will be generated in the second electromagnetic coil 34. During the lifting process, a part of the metal ring 32 will enter between the first electromagnetic coil 33 and the second electromagnetic coil 34. The intervention of the metal ring 32 will have a resistance effect on the magnetic field created by the first electromagnetic coil 33, thereby reducing the current generated by the second electromagnetic coil 34, thereby determining the specific location and degree of unqualified appearance of the headlight, and improving the detection effect.

[0045] A straight groove 42 is provided in the middle of the top of the placement table 41, and clamps 43 are movably connected to both sides of the interior of the straight groove 42.

[0046] Specifically, when performing light intensity detection, the car lights are powered on to make the light shine on the photoresistor board 47. The brightness of the car lights is sensed by the photoresistor board 47 and converted into an electrical signal for further processing and recording of light intensity data. At the same time, the coordinated extension and retraction of the six electric cylinders 39 realizes six degrees of freedom, namely, translation along the X, Y, and Z directions and rotation around the X, Y, and Z axes, as well as the compound movement of these degrees of freedom, to drive the placement table 41 and the clamped car lights to shake at multiple angles and in multiple directions, simulating various road conditions that the car may encounter during driving, and then observing the changes in light intensity data captured by the photoresistor board 47, thereby improving the accuracy of the car lights in light intensity detection.

[0048] Specifically, when detecting reflective lamps such as rearview reflective lamps, the laser emitter 49 is turned on, and the laser emitter 49 emits a pulsed laser beam to illuminate the reflective lamp. The electric telescopic rod 50 drives the mounting frame rod 48 to swing, thereby changing the irradiation position of the laser beam. The lifting cylinder 37 is used to control the lifting of the placement table 41 and the headlights, and the laser beam is reflected onto the receiver 51. The change in laser intensity received by the receiver 51 is observed to determine the reflective performance evaluation of the reflective lamp. In addition, the fill light 52 can be turned on to observe the reflective performance of the reflective lamp under different ambient light intensities.
