[0002] Automotive lights serve multiple functions, including illumination and warning lights. Beyond their functional role, their appearance after installation on the vehicle body is also subject to strict requirements. For example, the fit between the installed light and the body sheet metal must have a uniform gap to ensure a styling appearance. The component that the installed light contacts the body sheet metal is the lampshade; therefore, inspecting the lampshade after assembly is particularly important.

[0003] Currently, the common method for inspecting vehicle headlight covers is to use a positioning fixture to position the assembled headlight, and then workers use measuring needles to measure the positions to be inspected around the headlight cover one by one. This inspection process is cumbersome and time-consuming, which seriously affects the inspection efficiency. Summary of the Invention

The main body 10 includes a machine base 11 and a frame 12 connected above the machine base 11. The top surface of the machine base 11 forms a pick-and-place station 101 and a testing station 102 sequentially from the front end to the rear end. The reciprocating conveying structure 20 is installed on the top surface of the machine base 11 and includes a function to... A conveyor seat 21 reciprocates between the pick-and-place station 101 and the inspection station 102, and a linear drive unit 22 drives the conveyor seat 21 to reciprocate between the pick-and-place station 101 and the inspection station 102; a vehicle headlight positioning lower seat 40 is detachably mounted on the top surface of the conveyor seat 21, and two sets of vehicle headlight positioning clamps 41 are mounted side by side on the top of the vehicle headlight positioning lower seat 40, which position the vehicle headlight with the lampshade facing upwards; The lifting drive structure 30 is mounted on the frame 12, directly above the inspection station 102. The drive end of the lifting drive structure 30 faces the inspection station 102 and a lifting frame 31 is mounted on it. The bottom of the lifting frame 31 is detachably mounted with the lamp cover inspection seat 50. Two sets of measuring components 51 are mounted side by side at the bottom of the lamp cover inspection seat 50. The touch screen 60 is mounted on the frame 12, above the front end of the pick-and-place station 101. The vehicle lamp is placed on the vehicle lamp positioning seat 40 at the pick-and-place station 101 and positioned by the vehicle lamp positioning fixture 41. The linear drive unit 22 drives the conveyor seat 21 to transport the vehicle lamp from the pick-and-place station 101 to the inspection station 102. The drive end of the lifting drive structure 30 extends, causing the lamp cover inspection seat 50 to descend. Each measuring component 51 measures the lamp cover of a vehicle lamp on the vehicle lamp positioning fixture 41 and transmits the measurement data to the touch screen 60. The touch screen 60 displays the inspection results.

[0021] Furthermore, in this embodiment, the front end of the frame 12 is a pick-and-place port 121, and two doors 122 are hinged to each other on the two rear sides of the frame 12. The two doors 122 can be opened and closed relative to the frame 12 to connect or close the detection station 102 to the outside.

[0022] Furthermore, in this embodiment, the linear drive unit 22 is disposed on the central axis of the top surface of the machine base 11; the top surface of the machine base 11 is provided with two first slide rails 23 on both sides of the linear drive unit 22 and two second slide rails 24 on both sides of the linear drive unit 22, and each first slide rail 23 and second slide rail 24 is equipped with a slider 201 that can slide along it; the drive end of the linear drive unit 22 and the slider 201 of each first slide rail 23 and second slide rail 24 are respectively connected to the bottom surface of the conveyor seat 21, so that when the linear drive unit 22 operates, it drives the conveyor seat 21 to slide along the first slide rail 23 and second slide rail 24.

[0023] Furthermore, in this embodiment, the linear drive unit 22 includes a stepper motor 221 and a lead screw transmission module 222. The stepper motor 221 is used to drive the lead screw of the lead screw transmission module 222 to rotate. The lead screw nut of the lead screw transmission module 222 is connected to the bottom surface of the conveyor seat 21 through a connecting block 223.

[0024] Furthermore, in this embodiment, the lifting drive structure 30 includes a main drive cylinder and two balancing drive cylinders arranged opposite to each other on both sides of the main drive cylinder. The main drive cylinder and the two balancing drive cylinders are installed on the top of the frame 12. The telescopic rods of the main drive cylinder and the two balancing drive cylinders are arranged vertically downward and connected to the lifting frame 31, so that the telescopic rods of the main drive cylinder and the two balancing drive cylinders can extend and retract synchronously, thereby driving the lifting frame 31 and the lamp cover detection seat 50 connected to the bottom of the lifting frame 31 to rise and fall.

[0025] Furthermore, in this embodiment, the detachable connection between the conveyor seat 21 and the lower headlight positioning seat 40, and the detachable connection between the lifting frame 31 and the upper headlight cover detection seat 50, can be flexibly designed according to actual needs, including but not limited to locking through mechanical locking structures, bolt connections, pneumatic locks, or hydraulic locks.

[0026] Furthermore, in this embodiment, the top surface of the lower headlight positioning seat 40 is provided with a plurality of limiting posts 42 at intervals along its edge, and the top of each limiting post 42 is recessed with a limiting opening 421; the bottom surface of the upper headlight cover detection seat 50 is provided with a plurality of limiting cones 52 at intervals along its edge, each limiting cone 52 corresponding to a limiting post 42, and the bottom of the limiting cone 52 is equipped with a cone head 521, so that the upper headlight cover detection seat 50 descends relative to the lower headlight positioning seat 40. After the cone head 521 penetrates the limiting opening 421, the top of the limiting post 42 abuts against the bottom of the limiting cone 52, thereby realizing the limiting function.

[0027] Furthermore, in this embodiment, the frame 12 is provided with sensors 123 on its inner walls on both sides, which correspond to the positions of the top of the limiting column 42 and the bottom of the limiting cone column 52, in order to control the extension and retraction amplitude of the drive end of the lifting drive structure 30.

[0028] Furthermore, in this embodiment, in conjunction with reference to... Figure 5The inspection station 102 is equipped with a lifting support unit 70 that can be raised and lowered relative to the top surface of the machine platform 11 between each first slide rail 23 and the second slide rail 24 on the same side. The conveyor seat 21 has an outlet that passes through the top and bottom surfaces of each lifting support unit 70. When the lifting support unit 70 is in the retracted state, it is located below the conveyor seat 21. When the conveyor seat 21 moves to the inspection station 102 and disconnects the connection between the conveyor seat 21 and the lower seat 40 of the vehicle headlight positioning, the driving end of the lifting support unit 70 passes through the outlet and supports the lower seat 40 of the vehicle headlight positioning above the conveyor seat 21.

[0029] Furthermore, in this embodiment, the lifting support unit 70 includes a lifting drive cylinder 71 installed on the top surface of the machine base 11 and a support plate 72 disposed above the lifting drive cylinder 71. The telescopic rod of the lifting drive cylinder 71 is vertically upward and a top plate 73 is provided on it. The top plate 73 is connected to the bottom surface of the support plate 72. Several roller seats 721 are provided at intervals on both sides of the top surface of the support plate 72. The rotatable direction of the roller on each roller seat 721 is the same as the conveying direction of the conveying seat 21. Vertical guide rail assemblies 74 are provided between the outer walls of both sides of the support plate 72 and the adjacent first slide rail 23 or second slide rail 24 to improve the lifting stability and load-bearing capacity of the support plate 72.

[0030] Furthermore, in this embodiment, the vehicle lamp positioning fixture 41 and the measuring component 51 are a matching structure. The specific structure can be flexibly designed according to the structure of the vehicle lamp. When the type of vehicle lamp to be detected needs to be changed, the lower vehicle lamp positioning seat 40 and the upper lamp cover detection seat 50 of the corresponding type of vehicle lamp can be replaced on the vehicle lamp cover detection device.

[0031] Understandably, the method of using the vehicle lamp cover testing device of the present invention includes the following steps: First, the worker, outside the machine body, places each vehicle lamp onto a vehicle lamp positioning fixture 41 of the vehicle lamp positioning lower seat 40 via the conveyor seat 21 of the movable pick-and-place station 101; Second, the vehicle lamp cover testing device is activated. After the vehicle lamp positioning fixture 41 positions the vehicle lamp, the linear drive unit 22 drives the conveyor seat 21 to transport it from the pick-and-place station 101 to the testing station 102, and the driving end of the lifting drive structure 30... The lamp cover detection seat 50 extends and descends, with each measuring component 51 measuring the lamp cover of a vehicle lamp on a vehicle lamp positioning fixture 41 and transmitting the measurement to the touch screen 60. The detection result is displayed on the touch screen 60. Subsequently, the driving end of the lifting drive structure 30 retracts, causing the lamp cover detection seat 50 to rise and reset. The linear drive unit 22 drives the conveyor seat 21 to transport the lamp from the detection station 102 to the pick-up and put-down station 101. Based on the detection result, the worker places the retrieved vehicle lamp in the good product storage area or the defective product storage area.

[0032] The steps for changing the type of vehicle headlight being inspected are as follows: First, the conveyor seat 21 moves to the inspection station 102, extending from the drive end of the lifting drive structure 30 to lower the headlight cover inspection seat 50. Then, the connection between the headlight cover inspection seat 50 and the lifting frame 31 is released, allowing the headlight cover inspection seat 50 to stand upright above the headlight positioning seat 40 with the cooperation of the limiting column 42 and the limiting cone column 52. Second, the connection between the conveyor seat 21 and the headlight positioning seat 40 is released, and the lifting support unit 70 is activated. When the lifting support unit 70 switches from the retracted state to the extended state, the drive end of the lifting support unit 70 passes through the outlet, supporting the headlight positioning seat 40 and the headlight cover inspection seat 50 above the conveyor seat 21. Third, the two doors 122 at the rear of the machine frame 12 are opened, and the transfer cart is moved to... After the transfer cart is detachably locked to the rear of the main body 10, the lower headlight positioning seat 40 and the upper headlight cover detection seat 50 are manually pushed onto the transfer cart. After the transfer cart is unlocked from the main body 10, the transfer cart and the lower headlight positioning seat 40 and the upper headlight cover detection seat 50 are transported to the storage location. In the fourth step, another transfer cart carrying the replacement lower headlight positioning seat 40 and the upper headlight cover detection seat 50 are moved to the rear of the main body 10 and detachably locked to the main body 10. The replacement lower headlight positioning seat 40 and the upper headlight cover detection seat 50 are then manually pushed onto the lifting support unit 70. As the lifting support unit 70 switches from the extended state to the retracted state, the replacement lower headlight positioning seat 40 is detachably connected to the conveyor seat 21, and the replacement upper headlight cover detection seat 50 is detachably connected to the lifting frame 31. In this way, the headlight cover detection device changes the type of headlight being detected.

[0033] In summary, the vehicle lamp cover testing device of the present invention, through the cooperation of the main body 10, the reciprocating conveying structure 20, the lifting drive structure 30, the vehicle lamp positioning lower seat 40, the lamp cover testing upper seat 50, and the touch screen 60, only requires the worker to place the vehicle lamp positioning fixture 41 of the vehicle lamp positioning lower seat 40, which is conveyed to the pick-and-place station 101, into the vehicle lamp to be tested. The reciprocating conveying structure 20 automatically transports the vehicle lamp positioning lower seat 40 from the pick-and-place station 101 to the testing station 102. The cooperation between the lifting drive structure 30 and the lamp cover testing upper seat 50 achieves efficient testing of the vehicle lamp cover. After testing, the reciprocating conveying structure 20 automatically transports the vehicle lamp positioning lower seat 40 from the testing station 102 to the pick-and-place station 101, so that the worker can take out the tested vehicle lamp.
