Description

Technical Field

[0001] This invention relates to the field of vehicle headlight testing equipment technology, and in particular to a headlight cover testing device that facilitates the replacement of headlight testing fixtures. Background Technology

[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 the dimensions of automotive headlight covers is to use a testing fixture, which includes a positioning clamp and a testing seat that can be raised and lowered relative to the positioning clamp. After the positioning clamp positions the assembled headlight, the testing seat lowers relative to the positioning clamp, and the measuring instruments on the testing seat measure the positions to be inspected around the headlight cover. However, when it is necessary to change to a testing fixture for inspecting a different type of headlight, it is necessary to separate the positioning clamp from the testing seat one by one and transport them out by sling. The replacement process is cumbersome and time-consuming. Summary of the Invention

[0004] The purpose of this invention is to provide a lamp cover testing device that facilitates the replacement of vehicle lamp testing fixtures.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A lamp cover testing device that facilitates the replacement of vehicle lamp testing fixtures includes a main body, a reciprocating conveying structure, a lifting drive structure, a vehicle lamp positioning lower fixture, and a lamp cover testing upper fixture.

[0007] The main body includes a machine platform and a frame connected above the machine platform. The top surface of the machine platform forms a pick-and-place station and a testing station from the front end to the rear end. The front end of the frame is a pick-and-place port, and two doors are hinged to each other on opposite sides of the rear end of the frame. The testing station can be opened or closed to the outside by opening and closing the two doors relative to the frame.

[0008] The reciprocating conveying structure is installed on the top surface of the machine tool, including a conveyor seat that can reciprocate between the pick-up and place station and the inspection station. The lower seat for positioning the vehicle lamp is detachably installed on the top surface of the conveyor seat. The lifting drive structure is installed on the machine frame and located directly above the inspection station. A lifting frame is installed on the drive end of the lifting drive structure. The upper seat for detecting the lamp cover is detachably installed at the bottom of the lifting frame.

[0009] The top surface of the lower headlight positioning base is provided with several limiting posts along its edge spacing, and the top of each limiting post is recessed with a limiting opening; the bottom surface of the upper headlight cover detection base is provided with several limiting cones along its edge spacing, each limiting cone corresponding to a limiting post, and the bottom of the limiting cone is equipped with a cone head, so that the upper headlight cover detection base descends relative to the lower headlight positioning base, and after the cone head passes through the limiting opening, the top of the limiting post abuts against the bottom of the limiting cone.

[0010] The testing station is equipped with a lifting support unit that can be raised and lowered relative to the top surface of the machine. The conveyor seat has an outlet that passes through the top and bottom surfaces of each lifting support unit, so that when the lifting support unit is in the retracted state, it is located below the conveyor seat, and when the lifting support unit switches from the retracted state to the extended state, the drive end of the lifting support unit can pass through the outlet.

The telescopic rod of the lifting drive cylinder is arranged vertically upward and a top plate is provided on it. The top plate is connected to the bottom surface of the support plate. Several roller seats are arranged at intervals on both sides of the top surface of the support plate. The rotatable direction of the roller on each roller seat is the same as the conveying direction of the conveying seat.

[0012] As a further technical solution of the present invention: a vertical guide rail assembly is provided between the outer walls of both sides of the support plate and the adjacent first or second slide rail.

[0013] As a further technical solution of the present invention: two sets of vehicle lamp positioning fixtures are installed side by side on the top of the vehicle lamp positioning lower seat, and the vehicle lamp is positioned with the lampshade facing upward by the vehicle lamp positioning fixtures; two sets of measuring components are installed side by side on the bottom of the lampshade detection upper seat, so that the vehicle lamp is placed on the vehicle lamp positioning lower seat at the pick-up and place station and positioned by the vehicle lamp positioning fixtures. After that, the conveyor seat is transported from the pick-up and place station to the detection station. The driving end of the lifting drive structure extends and drives the lampshade detection upper seat to descend. Each measuring component measures the lampshade of the vehicle lamp on one vehicle lamp positioning fixture.

[0014] As a further technical solution of the present invention: the reciprocating conveying structure includes a linear drive unit for driving the conveyor seat to reciprocate between the pick-up / placement station and the inspection station. The linear drive unit is arranged on the central axis of the top surface of the machine tool. The top surface of the machine tool is provided with two first slide rails on both sides of the linear drive unit and two second slide rails on both sides of the linear drive unit. Each first slide rail and each second slide rail is equipped with a slider that can slide along it. The drive end of the linear drive unit and the slider of each first slide rail and each second slide rail are respectively connected to the bottom surface of the conveyor seat, so that when the linear drive unit operates, it drives the conveyor seat to slide along the first slide rail and the second slide rail.

[0015] As a further technical solution of the present invention: there are two sets of lifting support units, and each of the lifting support units is installed between the first slide rail and the second slide rail on the same side at the detection station.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention proposes a lamp cover detection device for convenient replacement of vehicle lamp detection fixtures. Through the cooperation between the main body, reciprocating conveying structure, lifting drive structure, lower lamp positioning seat and upper lamp cover detection seat, after the connection between the upper lamp cover detection seat and the lifting frame and the connection between the conveying seat and the lower lamp positioning seat, the lower lamp positioning seat and the upper lamp cover detection seat can be combined together. The lifting support unit switches from the retracted state to the extended state, supporting the combined lower lamp positioning seat and upper lamp cover detection seat above the conveying seat, and then pushing them together for replacement, effectively improving the replacement efficiency of vehicle lamp detection fixtures.

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... The system includes a conveyor seat 21 for reciprocating transport between the pick-and-place station 101 and the inspection station 102, and a linear drive unit 22 for driving 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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 lamp cover detection device.

[0034] Understandably, the method of using the lamp cover testing device includes the following steps: First, the worker, outside the machine, places each car lamp onto a car lamp positioning fixture 41 of the car lamp positioning lower seat 40 via the conveyor seat 21 of the moving pick-and-place station 101; Second, the lamp cover testing device is activated. After the car lamp positioning fixture 41 positions the car lamp, the linear drive unit 22 drives the conveyor seat 21 from the pick-and-place station 101 to the testing station 102. The drive end of the lifting drive structure 30 extends, causing the lamp cover testing upper seat 50 to descend. Each measuring component 51 measures the lamp cover of a car lamp on the car lamp positioning fixture 41 and transmits the measurement to the touch screen 60. The test result is displayed on the touch screen 60. Subsequently, the drive end of the lifting drive structure 30 retracts, causing the lamp cover testing upper seat 50 to rise and reset. The linear drive unit 22 drives the conveyor seat 21 from the testing station 102 to the pick-and-place station 101. Based on the test result, the worker places the retrieved car lamp into the good product storage area or the defective product storage area.

[0035] When it is necessary to replace the headlight testing fixture, namely the headlight positioning lower fixture 40 and the headlight cover testing upper fixture 50, the steps are as follows: First, the conveyor seat 21 moves to the testing station 102, first extending from the drive end of the lifting drive structure 30, driving the headlight cover testing upper fixture 50 to descend, and then disconnecting the connection between the headlight cover testing upper fixture 50 and the lifting frame 31, so that the headlight cover testing upper fixture 50 is erected above the headlight positioning lower fixture 40 with the cooperation of the limiting column 42 and the limiting cone column 52; Second, disconnect the connection between the conveyor seat 21 and the headlight positioning lower fixture 40 and start the lifting support unit 70. 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 through-hole, supporting the headlight positioning lower fixture 40 and the headlight cover testing upper fixture 50 above the conveyor seat 21; Third, open the two doors 122 at the rear of the machine frame 12. The transfer cart is moved to the rear end of the main body 10. After the transfer cart is detachably locked to the main body 10, the headlight positioning lower seat 40 and the lampshade detection upper seat 50 are manually pushed onto the transfer cart. After the transfer cart is released from the main body 10, the transfer cart and the headlight positioning lower seat 40 and lampshade detection upper seat 50 are transported to the storage location. In the fourth step, another transfer cart carrying the replacement headlight positioning lower seat 40 and lampshade detection upper seat 50 is moved to the rear end of the main body 10 and detachably locked to the main body 10. The replacement headlight positioning lower seat 40 and lampshade detection upper seat 50 are 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 headlight positioning lower seat 40 is detachably connected to the conveyor seat 21, and the replacement lampshade detection upper seat 50 is detachably connected to the lifting frame 31. In this way, the lampshade detection device changes the type of headlight being detected.

[0036] In summary, the lamp cover testing device of the present invention, which facilitates the replacement of vehicle lamp testing fixtures, utilizes the cooperation between the main body 10, the reciprocating conveying structure 20, the lifting drive structure 30, the lower lamp positioning seat 40, and the upper lamp cover testing seat 50. After the connection between the upper lamp cover testing seat 50 and the lifting frame 31 is established and the connection between the conveying seat 21 and the lower lamp positioning seat 40 is disengaged, the lower lamp positioning seat 40 and the upper lamp cover testing seat 50 can be combined together. The lifting support unit 70 switches from a retracted state to an extended state, supporting the combined lower lamp positioning seat 40 and the upper lamp cover testing seat 50 above the conveying seat 21 for simultaneous replacement, effectively improving the replacement efficiency of vehicle lamp testing fixtures.

[0037] Any combination of various embodiments of the present invention, provided it does not violate the inventive concept of the present invention, shall be regarded as the content disclosed by the present invention; within the scope of the technical concept of the present invention, any simple modifications to the technical solution and any combination of different embodiments that do not violate the inventive concept of the present invention shall be within the protection scope of the present invention.
