Description

Technical Field

[0001] This invention relates to the field of automotive lighting, and more specifically, to an automatic testing device for automotive lighting. Background Technology

[0002] Car headlights are an essential component for nighttime driving and are closely related to driving safety. Since the invention of the automobile, car headlights have been developing and improving step by step. Today, there are many types of car headlights, with halogen headlights, xenon headlights, and LED headlights being the mainstream types.

[0003] For example, the vehicle lamp testing equipment authorized by announcement number CN 109781391 A can automatically assemble and test vehicle lamps, greatly improving assembly efficiency and test yield. However, when testing vehicle lamps, the test is based on the assembled vehicle lamp assembly. If the test results do not meet the standards, it is necessary to replace the lamp beads or lamp covers and test again. The lamp beads can be replaced by changing the slot, but the lamp covers in the assembly are fixed by sealant, which is inconvenient to disassemble and replace, and is not conducive to disassembling and replacing components after testing. Summary of the Invention

[0004] This invention provides an automatic testing device for vehicle lights, which solves the technical problem in related technologies where the lamp cover is sealed and difficult to disassemble when the vehicle light assembly fails the test.

[0005] According to one aspect of the present invention, an automatic testing device for vehicle lights is provided, including a lamp component to be tested, a worktable, a drive unit, a bracket unit, and a pressing unit. The lamp component includes a lamp holder and a lamp cover. The lamp cover is installed on the inner edge of one end of the lamp holder. The worktable is horizontally arranged. The bracket unit is parallel to the top of the worktable. The lamp holder can be assembled onto the bracket unit. The pressing unit is arranged perpendicular to the table surface of the worktable, and the lamp cover is inverted and assembled onto the top of the pressing unit. A transmission unit is provided between the bracket unit and the pressing unit.

[0006] The bracket unit includes a tray, a compartment, a power connector, and a voltage regulator. The compartment is located at the bottom of the tray, and the voltage regulator is located at the bottom of the tray near the transmission unit. The power connector is installed on the inner wall of one side of the compartment. The power connector and the voltage regulator are electrically connected. A set of connectors is provided between the bottom of the voltage regulator and the inside of the worktable. When the bracket unit moves to one side of the worktable, the connectors connect the voltage regulator and the power supply inside the worktable.

[0007] The pressing unit is a multi-link structure. When the driving unit drives the bracket unit to move along the vertical direction, the transmission unit moves synchronously along the vertical direction. The transmission unit drives the pressing unit to deform, so that the pressing unit drives the lampshade to rotate 180° and rotates to the side of the bracket unit to press it onto the lamp holder.

[0008] It also includes a testing frame, which is located directly above the bracket unit. When the lamp is powered on, the light beam shines onto the inner top wall of the testing frame. The testing frame contains a testing component that detects the light intensity of the light beam emitted by the lamp.

[0009] Furthermore, the pressing unit includes a fixed seat, a fixed rod, a first connecting rod, a second connecting rod, and a T-shaped connecting rod. The fixed seat is located on the upper surface of the workbench, the fixed rod is installed on the outer wall of the fixed seat, the first connecting rod and the second connecting rod are movably connected to the two ends of the fixed rod, the other end of the first connecting rod is movably connected to the bottom end of the T-shaped connecting rod, and the other end of the second connecting rod is movably connected to the middle part of the T-shaped connecting rod.

[0010] Furthermore, the top of the T-shaped connecting rod is provided with a pneumatic suction cup, which is used to provide the adsorption force for fixing the lampshade.

[0011] Furthermore, a drive shaft extends from the connection point between the first connecting rod and the fixed rod, and the drive shaft is connected to the transmission unit.

[0012] Furthermore, a CCD camera is mounted on the top of the mounting base, and the CCD camera is used to capture images of the lampshade in an inverted state.

[0013] Furthermore, the transmission unit includes a fixed rack, a gear, and a cross arm. The fixed rack is installed at the end of the cross arm, and the length direction of the fixed rack is perpendicular to the length direction of the cross arm. The other end of the cross arm is connected to the bracket unit. The gear is installed at the shaft end of the drive shaft, and the gear is meshed with the fixed rack.

[0014] Furthermore, the drive unit includes a drive motor, a stepper screw, a sliding seat, and a vertical rod. The vertical rod is perpendicular to the workbench surface, and the sliding seat is sleeved on the vertical rod. One side of the support plate is fixedly connected to the sliding seat. The drive motor is mounted on the side wall of the workbench. One end of the stepper screw is mounted on the output shaft of the drive motor, and the other end of the stepper screw is mounted inside the sliding seat. The drive motor drives the stepper screw to rotate, and the stepper screw drives the sliding seat to move along the length direction of the stepper screw.

[0015] Furthermore, the upper surface of the workbench near the bracket unit is provided with a tray, which is compatible with the specifications of the tray and the bottom side of the voltage regulator.

[0016] Furthermore: the connector includes an energizing plate and a connecting seat. The energizing plate is located on the bottom side of the voltage regulator and is electrically connected to the voltage regulator. The connecting seat is located on one inner wall of the bracket.

[0017] Furthermore, each of the four corners of the testing frame is equipped with a bracket, which is perpendicular to the upper surface of the workbench, and each of the four corners of the tray has a sliding groove, through which the bracket passes.

[0018] The beneficial effects of this invention are as follows:

[0019] This automatic vehicle lighting testing equipment clamps the lamp holder and lamp cover separately and automatically assembles them into a lighting fixture. It can also independently test the performance of the lamp cover and its combined lamp holder. After the test is passed, the connection between the lamp cover and the lamp holder is sealed and fixed with glue. This avoids the problem of traditional vehicle lighting assembly integrated testing, where the lamp cover needs to be disassembled and components replaced if the test fails.

[0020] At the same time, the main components of the lamp holder, the lamp beads, were tested to see if they were damaged and whether their working conditions met the standards. This ensured that the lighting of the lamps in actual working conditions could cover the driver's standard visual range in front, thus ensuring the driver's safety. Attached Figure Description

Detailed Implementation

[0029] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0030] Example 1

[0031] See Figures 1-7 As shown, this embodiment proposes an automatic vehicle lamp testing device, including a lamp component 800 to be tested, a workbench 100, a drive unit 600, a bracket unit 200, and a pressing unit 400. The lamp component 800 includes a lamp holder 810 and a lamp cover 820. The lamp cover 820 is installed on the inner edge of one end of the lamp holder 810. The workbench 100 is horizontally set, and the bracket unit 200 is parallel to the top of the workbench 100. The lamp holder 810 can be assembled onto the bracket unit 200. The pressing unit 400 is set perpendicular to the upper surface of the workbench 100, and the lamp cover 820 is inverted and assembled onto the top of the pressing unit 400. A transmission unit 700 is provided between the bracket unit 200 and the pressing unit 400.

[0032] The bracket unit 200 includes a tray 210, a storage compartment 220, a power connector 240, and a voltage regulator 250. The storage compartment 220 is located at the bottom end of the tray 210, and the voltage regulator 250 is located at the bottom end of the tray 210 near the transmission unit 700. The power connector 240 is installed on the inner wall of one side of the storage compartment 220. The power connector 240 and the voltage regulator 250 are electrically connected. A set of connectors is provided between the bottom end of the voltage regulator 250 and the interior of the workbench 100. When the bracket unit 200 moves to one side of the workbench 100, the connectors connect the voltage regulator 250 and the power supply inside the workbench 100.

[0033] The pressing unit 400 has a multi-link structure. When the drive unit 600 drives the bracket unit 200 to move along the vertical direction, the transmission unit 700 moves synchronously along the vertical direction. The transmission unit 700 drives the pressing unit 400 to deform, so that the pressing unit 400 drives the lamp cover 820 to rotate 180° and rotates and presses it onto the lamp holder 810 on the side of the bracket unit 200.

[0034] It also includes a testing frame 300, which is located directly above the bracket unit 200. The light beam emitted by the lamp 800 after it is powered on shines onto the inner wall of the top of the testing frame 300. The testing frame 300 is equipped with a testing component, which detects the light intensity of the light beam emitted by the lamp 800. Supports are installed at the four corners of the testing frame 300. The supports are perpendicular to the upper surface of the workbench 100, and the four corners of the tray 210 are provided with sliding grooves. The supports pass through the inner wall of the sliding grooves.

[0035] The pressing unit 400 includes a fixed base 410, a fixed rod 420, a first connecting rod 430, a second connecting rod 440, and a T-shaped connecting rod. The fixed base 410 is located on the upper surface of the workbench 100. The fixed rod 420 is installed on the outer wall of the fixed base 410. The first connecting rod 430 and the second connecting rod 440 are movably connected to the two ends of the fixed rod 420, respectively. The other end of the first connecting rod 430 is movably connected to the bottom end of the T-shaped connecting rod, and the other end of the second connecting rod 440 is movably connected to the middle part of the T-shaped connecting rod. The top end of the T-shaped connecting rod is provided with a pneumatic suction cup 480, which is used to provide suction force for fixing the lampshade 820. A drive shaft 450 extends from the connection between the first connecting rod 430 and the fixed rod 420, and the drive shaft 450 is connected to the transmission unit 700.

[0036] It should be noted that the T-shaped connecting rod includes a third connecting rod 460 and a connecting frame 470. The third connecting rod 460 is vertically installed at the bottom of the connecting frame 470, and the connecting frame 470 is L-shaped. The inner side of the connecting frame 470 is provided with a mounting groove. The pneumatic suction cup 480 is installed into the mounting groove. The two connecting frames 470 enclose a rectangular cavity, and the lampshade 820 is placed inverted in the rectangular cavity.

[0037] The transmission unit 700 includes a fixed rack 710, a gear 720, and a cross arm 730. The fixed rack 710 is mounted to the end of the cross arm 730, and the length direction of the fixed rack 710 is perpendicular to the length direction of the cross arm 730. The other end of the cross arm 730 is connected to the bracket unit 200. The gear 720 is mounted on the shaft end of the drive shaft 450, and the gear 720 is meshed with the fixed rack 710.

[0038] A CCD camera 500 is mounted on the top of the mounting base 410. The CCD camera 500 is used to capture images of the lampshade 820 in an inverted state. The captured images are displayed on the control panel on one side of the workbench 100. The control panel is equipped with a command button group and a touch screen. The control panel is used to control the equipment testing process.

[0039] Use a CCD camera 500 to capture images of the appearance of the lampshade 820 to avoid damage or wear on the surface of the lampshade 820, which would affect the light transmittance of subsequent inspections.

[0040] The drive unit 600 includes a drive motor 610, a stepper screw 620, a sliding seat 630, and a vertical rod 640. The vertical rod 640 is perpendicular to the upper surface of the worktable 100, and the sliding seat 630 is sleeved on the vertical rod 640. One side of the support plate 210 is fixedly connected to the sliding seat 630. The drive motor 610 is mounted on the side wall of the worktable 100. One end of the stepper screw 620 is mounted on the output shaft of the drive motor 610, and the other end of the stepper screw 620 is mounted inside the sliding seat 630. The drive motor 610 drives the stepper screw 620 to rotate, and the stepper screw 620 drives the sliding seat 630 to move along the length direction of the stepper screw 620.

[0041] The upper surface of the workbench 100 near the bracket unit 200 is provided with a tray 110. The tray 110 is compatible with the bottom specifications of the tray 220 and the voltage regulator 250. When the tray 210 moves down along the upright 640, the tray 220 extends into the tray 110. The connector on the voltage regulator 250 and the connector in the workbench 100 are connected and energized. After being energized, the lamp 800 works and shines a beam of light through the lamp cover 820 onto the detection frame 300.

[0042] The connectors include an energizing plate 260 and a connecting seat 120. The energizing plate 260 is located on the bottom side of the voltage regulator 250 and is electrically connected to the voltage regulator 250. The connecting seat 120 is located on one inner wall of the bracket 110.

[0043] This automatic vehicle headlight testing equipment is used to test whether the vehicle headlight works after being powered on, whether the light intensity of the beam passing through the lamp cover 820 at a certain distance meets the standard, and to test the condition of the lamp cover 820 itself. The specific operating procedure for completing these various tests is as follows:

[0044] 1. Install lighting fixtures 800

[0045] Install the target light holder 810 into the tray 220. The protruding part of the lower end of the light holder 810 passes through the lower through hole 230 located below the tray 220. The plug part reserved on the light holder 810 is inserted into the corresponding power connector 240 so that it is connected to the voltage regulator 250 through the power connector 240.

[0046] The convex side of the lampshade 820 is mounted on the pneumatic suction cup 480, and the lampshade 820 is in a horizontal state with the convex side of the lampshade 820 facing the CCD camera 500. The pneumatic suction cup 480 on the connecting bracket 470 mainly adsorbs the sharp corners of the edge of the lampshade 820, without blocking the main light-transmitting area of ​​the lampshade 820.

[0047] II. Lampshade 820 Inspection

[0048] The lampshade 820 is inspected by a CCD camera 500. The convex surface of the lampshade 820 faces the CCD camera 500, which can clearly detect defects on the outer arc surface of the lampshade 820 and display them on the touch screen. If there are defects, the suction of the pneumatic suction cup 480 is released, the lampshade 820 is removed and reworked. If there are no defects, subsequent inspections are carried out.

[0049] III. Power-on test

[0050] A flawless lampshade 820, with its convex surface facing downwards, is horizontally positioned on the pressing unit 400. The lamp holder 810 is positioned on the bracket unit 200. The drive unit 600 is activated, and its operation involves the drive motor 610 driving the stepper screw 620 to rotate. The rotation of the stepper screw 620 causes the sliding seat 630 to move along the vertical rod 640. Figure 2 As shown, the sliding seat 630 moves downward along the upright 640, causing the horizontal arm 730 and its connected fixed rack 710 to move. When the fixed rack 710 moves vertically, its tooth ends mesh with the gear 720. The gear 720 rotates, causing its connected drive shaft 450 to rotate. The drive shaft 450 rotates within the fixed seat 410, causing the second connecting rods 440 on both sides to rotate. Figure 7As shown, the rotation of the second link 440 causes the first link 430 and the third link 460 connected to it to rotate, completing the 180° rotation of the connecting frame 470 and rotating it a certain distance closer to the support plate 210. This distance is the position difference between the pressing unit 400 and the bracket unit 200. The distance is a fixed value. When the support plate 210 extends into the slot 110 of the worktable 100 and the lower surface of the support plate 210 abuts against the worktable 100, the pressing unit 400 completes its action and presses the lampshade 820 fixed by the pneumatic suction cup 480 on the connecting frame 470 onto the lamp holder 810. At this time, the power board 260 connected to the voltage regulator 250 on the lower side of the support plate 210 is combined with the connecting seat 120. The connecting seat 120 is connected to the power supply in the worktable 100. The power supply in the worktable 100 is a fixed power supply or is provided with a power connection wire and is powered on.

[0051] If the LEDs in the lamp holder 810 emit a beam of light after being powered on, it indicates that the LEDs in the lamp holder 810 are working after being powered on. The beam of light passes through the lamp cover 820 located above and is dispersed onto the detection frame 300. A light intensity sensor is provided on the inner wall of the top of the detection frame 300. If no beam of light is emitted after being powered on and the light intensity sensor does not detect a change in the light intensity of the beam, it indicates that the LEDs are damaged.

[0052] IV. Light Intensity Detection

[0053] When the lamp beads inside the lamp holder 810 are powered on, they emit a light beam. After passing through the lamp cover 820 located above, the light beam is dispersed onto the detection frame 300. The inner wall of the top of the detection frame 300 is equipped with a light intensity sensor. The light intensity sensor can detect the light intensity of the light beam after it has traveled a certain distance after the lamp holder 800 is working. This certain distance is consistent with the height of the bracket and can be changed by raising and lowering the bracket.

[0054] The bracket can be a lifting component, including but not limited to a hydraulic rod. According to different heights, the light intensity of the lamp component 800 reaches the testing frame 300. If the light intensity detection range is within the standard value range, it means that the lamp holder 810 and lampshade 820 of the lamp component 800 are qualified. If the light intensity detection range is not within the standard value range, it means that the lampshade 820 of the lamp component 800 is qualified, but the lamp holder 810 is unqualified and the internal components of the lamp holder 810 need to be replaced.

[0055] At the same time, the voltage output of the voltage regulator 250 is changed by using the control keys in the control panel. The lighting status of the lamp 800 under different voltages is observed to test whether the lamp 800 can complete the lighting work under low voltage, standard voltage and high voltage, thereby improving the working stability of the lamp 800 in actual working conditions.

[0056] V. Discharge after testing

[0057] When both the lampshade 820 and the lamp holder 810 inside the lamp fixture 800 are qualified, the pneumatic suction cup 480 does not work. The lampshade 820 and the lamp holder 810 are fixed by the movable clamp located on the support plate 210. Then the drive motor 610 reverses and drives the support plate 210 to move upward. At this time, the pressing unit 400 deforms in the opposite direction and returns to the initial state. The movable clamp fixes the positional relationship between the lampshade 820 and the lamp holder 810. After the support plate 210 rises, glue is squeezed into the connection between the lamp holder 810 and the lampshade 820 to fix the two. Then the entire lamp fixture 800 is taken out.

[0058] If the lamp holder 810 inside the lamp fixture 800 is defective, the pneumatic suction cup 480 will work. After the drive motor 610 reverses, it will drive the lamp cover 820 back to the inverted structure. At this time, the lamp holder 810 will be lifted to the initial position, the internal lamp chip components will be replaced, and a second inspection will be carried out until the lamp holder 810 of the lamp fixture 800 is qualified. After sealing, the material will be discharged.

[0059] It should be further explained that the movable clamp includes, but is not limited to, the sliding bar 270 and the clamping block 280. The bottom end of the clamping block 280 is slidably connected to the sliding bar 270. The sliding bar 270 is distributed on the outer side of the upper edge of the tray 220. The inner side of the clamping block 280 has a groove, which fits with the outer surface of the lamp cover 820. When the clamping block 280 moves to the side of the lamp cover 820, the groove of the clamping block 280 presses against the outer surface of the lamp cover 820 to fix it. At the same time, the clamping block 280 can be driven manually or by other driving components. The driving components include, but are not limited to, electric driving components, pneumatic components, and hydraulic components that can drive the clamping block 280 to move along the length direction of the sliding bar 270.

[0060] This automatic vehicle lighting testing equipment clamps the lamp holder 810 and the lamp cover 820 separately, and independently tests the performance of the lamp cover 820 and its combination with the lamp holder 810. After the test is passed, the connection between the lamp cover 820 and the lamp holder 810 is sealed and fixed with glue, avoiding the problem of traditional vehicle lighting assembly integrated testing, where the lamp cover 820 needs to be disassembled and the components replaced when the test fails.

[0061] At the same time, the lamp beads, the main components of the lamp holder 810, were tested for damage, and their working conditions were checked to ensure that the lighting of the lamp 800 in actual working conditions can cover the standard visual range in front of the driver, thus ensuring the driver's safety.

[0062] The embodiments of this embodiment have been described above with reference to the accompanying drawings. However, this embodiment is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this embodiment without departing from the spirit of this embodiment and the scope of protection of the claims, and all of these forms are within the protection scope of this embodiment.
