Description
Technical Field
[0001] This utility model relates to the field of lamp light pattern detection technology, and more specifically to a light source light pattern testing device. Background Technology
[0002] In the field of automotive technology, automotive lighting is a crucial component. Before leaving the factory, automotive lighting fixtures need to undergo light pattern testing. Only those that meet the light pattern requirements can be shipped. This light pattern testing must be conducted using specialized testing equipment.
[0003] Currently, when performing light pattern testing on automotive lighting modules, the lighting module is placed inside the testing chamber of a light pattern testing machine. During testing, the testing chamber is kept closed by a sealed door. After testing, the sealed door is opened, the tested light source module is removed, replaced, and the testing process is repeated. In this testing process, the loading and unloading of the light source module takes a lot of time, resulting in low overall testing efficiency of the light pattern testing machine, which is difficult to meet the usage requirements.
[0004] In view of this, the present invention proposes a light source pattern testing device to solve this problem. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a light source light pattern testing device to solve the problems existing in the background art.
[0006] This utility model provides the following technical solution: a light source light pattern testing device, including a testing machine, a testing cavity is opened inside the testing machine, a light pattern detector is embedded on the left side of the testing cavity, a base plate is fixedly installed at the bottom of the testing cavity, a testing plate is provided on the upper surface of the base plate, a tooling seat is provided on the upper surface of the testing plate, a positioning groove for positioning an external light source module is opened on the top of the tooling seat, and a replacement component is provided on the base plate corresponding to the position of the testing plate.
[0007] The transposition assembly includes a vertical shaft rotatably connected to the upper surface of the substrate, a test board fixedly mounted on the top of the vertical shaft, a worm gear fixedly mounted on the surface of the vertical shaft, a stepper motor fixedly mounted on the surface of the substrate, a worm fixedly mounted on the output shaft surface of the stepper motor, the worm meshing with the worm gear, and two tooling seats arranged in a circumferential array on the surface of the test board.
[0008] As a further description of the above technical solution: the surface of the testing machine is respectively fixedly mounted with a display screen, a control panel, status lights and an emergency stop switch.
[0009] As a further description of the above technical solution: a storage box is fixedly installed on the front of the testing machine, and a tool divider is provided on the inner wall of the storage box; by setting up the storage box, it is convenient to place various tools used in the testing process.
[0010] As a further description of the above technical solution: a partition plate is fixedly installed on the upper surface of the test plate. The partition plate is adapted to the shape of the test cavity, and an observation window is embedded in the surface of the partition plate. By setting the partition plate, the test cavity can be sealed before and after the test plate rotates to switch the tooling seat. The observation window allows for easy and direct observation of the inside of the test cavity.
[0011] As a further description of the above technical solution: the fixture base and the test plate are movably connected. A fixed frame is fixedly installed on the surface of the test plate, and the fixture base is snapped inside the fixed frame. A positioning screw is threadedly connected to the side wall of the fixed frame, and the threaded end of the positioning screw abuts against the surface of the fixture base. Because the fixture base and the test plate are movably connected, the fixture base can be replaced according to the model of the light source module and the positioning slot. After replacement, the positioning screw is used to clamp and install the fixture base, thereby improving the adaptability of the device.
[0012] As a further description of the above technical solution: the tooling base is provided with a self-clamping component inside the positioning groove. The self-clamping component includes a transmission cavity opened inside the tooling base. A connecting rod is slidably connected inside the transmission cavity. One end of the connecting rod extends to the right side wall of the positioning groove and is fixedly installed with a clamping plate. The other end of the connecting rod has a first inclined surface. A support plate is slidably connected to the bottom end of the positioning groove. The rod part at the bottom end of the support plate extends into the transmission cavity and has a second inclined surface. When the support plate moves down, the second inclined surface and the first inclined surface slide against each other and drive the clamping plate to move to the left. When testing the light source module, the light source module is placed inside the positioning groove. The light source module presses down on the support plate using its own weight. Then, through the sliding effect of the second inclined surface and the first inclined surface, the connecting rod drives the clamping plate to clamp and fix the light source module. The operation is convenient and no additional fixing action is required.
[0013] As a further description of the above technical solution: a return spring is fixedly installed on the inner wall of the transmission cavity, and the other end of the return spring abuts against the left end of the connecting rod; when the light source module is taken out, the elastic force of the return spring can be used to move the connecting rod and the clamping plate to the right to reset, which is convenient to avoid when the light source module is put in again, and is easy to use.
[0014] As a further description of the above technical solution: the test board is fitted with a terminal block, which is adapted to the terminal block on the surface of the external light source module. A conductive slip ring is fixedly installed on the surface of the vertical shaft, and the movable end of the conductive slip ring is electrically connected to the test machine. By setting the conductive slip ring and the terminal block, it is convenient to provide rotary power to the light source module, ensuring the power supply requirements of the light source module during continuous testing.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] 1. Compared with the prior art, this light source pattern testing device positions the light source module inside the positioning groove on the top of the fixture. By setting up a switching component, a stepper motor drives the worm gear to rotate. Based on the meshing of the worm gear and the worm wheel, the vertical shaft can be rotated to switch the position of the two fixtures. In this case, while one fixture is located inside the test chamber for light pattern testing, the light source module can be loaded and unloaded on the surface of the other fixture located outside the test chamber. This method can save the time of assembling and unloading the light source module, thereby greatly improving the testing efficiency in batch testing.
[0017] 2. Compared with existing technologies, this light source pattern testing device, by setting a partition plate, can maintain the sealing effect on the test chamber before and after switching the fixture seat by rotating the test plate, while the observation window allows for convenient and direct observation of the test chamber's interior. The fixture seat and test plate are movably connected, allowing the fixture seat to be replaced according to the model of the light source module and the positioning slot. After replacement, the fixture seat is clamped and installed using positioning screws, thereby improving the device's adaptability. When testing the light source module, the light source module is placed inside the positioning slot. The light source module utilizes its own weight to press down on the support plate. The sliding action between the second and first inclined surfaces drives the connecting rod to clamp and secure the light source module. This operation is convenient and requires no additional fixing action. A return spring is included; when the light source module is removed, its elasticity allows the connecting rod and clamp to return to their original position to the right, facilitating subsequent insertion and ensuring ease of use. A conductive slip ring and terminal block facilitate rotary power supply to the light source module, ensuring sufficient power for continuous testing. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The light source light pattern testing device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] Reference Figures 1 to 5 This utility model provides a light source light pattern testing device, including a testing machine 1. The surface of the testing machine 1 is fixedly mounted with a display screen 12, a control panel 13, status lights and an emergency stop switch.
[0026] A storage box 14 is fixedly installed on the front of the testing machine 1, and a tool divider 15 is provided on the inner wall of the storage box 14.
[0027] By setting up storage box 14, it is convenient to place various tools used during the testing process.
[0028] The testing machine 1 has a testing chamber 2 inside. A light pattern detector 3 is embedded on the left side of the testing chamber 2. A base plate 4 is fixedly installed at the bottom of the testing chamber 2. A testing plate 5 is provided on the upper surface of the base plate 4. A partition plate 16 is fixedly installed on the upper surface of the testing plate 5. The partition plate 16 is adapted to the shape of the testing chamber 2. An observation window 17 is embedded on the surface of the partition plate 16.
[0029] Furthermore, by setting up the partition plate 16, the test chamber 2 can be sealed off when the test plate 5 rotates to switch the tooling seat 6, and the observation window 17 allows for easy and intuitive observation of the test status inside the test chamber 2.
[0030] The upper surface of the test board 5 is provided with a fixture 6, and the top of the fixture 6 is provided with a positioning groove 7 for positioning the external light source module.
[0031] The tooling base 6 is provided with a self-clamping assembly inside the positioning groove 7. The self-clamping assembly includes a transmission cavity 20 opened inside the tooling base 6. A connecting rod 21 is slidably connected inside the transmission cavity 20. One end of the connecting rod 21 extends to the right side wall of the positioning groove 7 and is fixedly installed with a clamping plate 24. The other end of the connecting rod 21 is provided with a first inclined surface 25. A support plate 26 is slidably connected to the bottom end of the positioning groove 7. The rod part at the bottom end of the support plate 26 extends into the transmission cavity 20 and is provided with a second inclined surface 27. When the support plate 26 moves down, the second inclined surface 27 and the first inclined surface 25 slide against each other and drive the clamping plate 24 to move to the left.
[0032] It is worth noting that by setting up a self-clamping component, when testing the light source module, the light source module is placed inside the positioning groove 7, and the light source module presses down on the support plate 26 using its own weight. Then, through the abutting sliding effect between the second inclined surface 27 and the first inclined surface 25, the connecting rod 21 drives the clamping plate 24 to clamp and fix the light source module. The operation is convenient, no additional fixing action is required, and the testing efficiency is improved.
[0033] A return spring 28 is fixedly installed on the inner wall of the transmission cavity 20, and the other end of the return spring 28 is pressed against the left end of the connecting rod 21.
[0034] Furthermore, when the light source module is removed, the spring force of the reset spring 28 can be used to move the connecting rod 21 and the locking plate 24 to the right and reset them, which makes it easier to avoid obstacles when the light source module is put back into the positioning slot 7 later, making it convenient to use.
[0035] A transposition component is provided on the substrate 4 at the position corresponding to the test board 5.
[0036] The transposition assembly includes a vertical shaft 8 rotatably connected to the upper surface of the substrate 4, a test plate 5 fixedly mounted on the top of the vertical shaft 8, a worm gear 9 fixedly mounted on the surface of the vertical shaft 8, a stepper motor 10 fixedly mounted on the surface of the substrate 4, a worm 11 fixedly mounted on the output shaft surface of the stepper motor 10, the worm 11 meshing with the worm gear 9, and two tooling seats 6 arranged in a circumferential array on the surface of the test plate 5.
[0037] It is worth noting that by setting up a switching component, the stepper motor 10 drives the worm gear 11 to rotate. Based on the meshing of the worm gear 11 and the worm wheel 9, the vertical shaft 8 can be rotated to switch the positions of the two tooling seats 6. In this case, while one tooling seat 6 is located inside the test cavity 2 for light pattern testing, the light source module can be installed and removed on the surface of the other tooling seat 6 located outside the test cavity 2. This method can save the time of assembling and removing the light source module, thereby greatly improving the testing efficiency during batch testing.
[0038] The test board 5 is fitted with a terminal block 22, which is compatible with the terminal block on the surface of the external light source module. A conductive slip ring 23 is fixedly installed on the surface of the vertical shaft 8, and the movable end of the conductive slip ring 23 is electrically connected to the test machine 1.
[0039] It is worth noting that by setting the conductive slip ring 23 and the terminal block 22, it is convenient to rotate the power supply to the light source module, ensuring the power supply needs of the light source module during continuous testing.
[0040] The fixture 6 and the test plate 5 are movably connected. A fixing frame 18 is fixedly installed on the surface of the test plate 5. The fixture 6 is snapped inside the fixing frame 18, and a positioning screw 19 is threadedly connected to the side wall of the fixing frame 18. The threaded end of the positioning screw 19 abuts against the surface of the fixture 6.
[0041] Furthermore, since the tooling base 6 and the test plate 5 are movably connected, the tooling base 6 can be replaced according to the model of the light source module and the positioning slot 7. After replacement, the positioning screw 19 is used to clamp and install the tooling base 6, thereby improving the adaptability of the device.
[0042] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
