Description

Technical Field

[0001] This utility model belongs to the field of automotive ambient lighting processing, specifically relating to an electronic circuit board processing and testing device for automotive ambient lighting. Background Technology

[0002] Ambient lighting in automobiles is a lighting device used to enhance the interior environment and driving experience. It is typically installed inside the vehicle, such as on the dashboard, door frames, under seats, or center console, providing a soft and adjustable lighting effect. Ambient lighting generally allows users to adjust the brightness via the vehicle's system or a physical switch to suit different scenarios. For example, lower brightness is needed to avoid glare when driving at night, while higher brightness can be used for parties or leisure trips. Some models also support dynamic changing modes, such as flashing in rhythm with music, enhancing entertainment and interactivity, and providing drivers and passengers with a richer and more diverse visual experience. In short, ambient lighting in automobiles is not just a decorative element; it adds a technological element to modern vehicles and reflects consumers' new trends in self-expression and pursuit of quality of life.

[0003] Automotive ambient lighting requires electronic circuit boards (PCBs) for in-vehicle control. After the PCBs are manufactured, visual inspection is a crucial step to ensure their performance and quality. Visual inspection checks for obvious defects on the PCB surface, such as scratches, dirt, or poor soldering. It also ensures that components are correctly positioned and not missing. Manufacturing inspection also includes functional testing of the PCBs, including testing each LED to ensure it functions properly, including brightness uniformity and color accuracy.

[0004] Currently, most electronic circuit board visual inspection devices used in automotive ambient lighting manufacturing employ specialized fixed molds to hold the electronic circuit boards in place. When the dimensions to be inspected change, the fixed mold must be replaced to secure the electronic circuit board. For example, the device with publication number CN... Patent document 116213297A, published on 2023-06-06, entitled "Automotive Ambient Light Testing Device and Testing Method," discloses a device comprising: a frame, a housing, a turntable mechanism, a bracket, a luminance and colorimeter, a controller, and a display. The turntable mechanism is mounted on the frame, and the turntable mechanism has a first station and a second station. The frame also has a loading station and a testing station. The housing is located at the testing station, and the bracket is located inside the housing. The luminance and colorimeter is mounted on the bracket and connected to the controller. The controller is connected to the display, and the controller and display are respectively located on the side wall of the housing. The turntable mechanism is used to transport the product to be tested from the loading station to the testing station from the first station or the second station. Both the first and second stations are equipped with carrier positioning components.

[0005] This method not only requires the prefabrication of numerous fixed molds, increasing usage costs, but also suffers from insufficient stability in the positioning of the electronic circuit board when its dimensions do not match the prefabricated mold dimensions, leading to inaccurate visual inspection. Therefore, this paper proposes a processing and inspection device for electronic circuit boards used in automotive ambient lighting to address these issues. Utility Model Content

The output end of the second guide rod cylinder is set obliquely and a second visual inspection camera is installed at its end.

[0011] As a further improvement of this utility model, the electronic circuit board limiting assembly includes a platform plate disposed on the upper surface of the detection platform. Two linear guide rails are arranged parallel to each other on the upper surface of the platform plate in the transverse direction. Two guide rail sliders are slidably disposed on each of the two linear guide rails. A crossbeam platform is jointly supported on the upper surface of the two adjacent guide rail sliders. Both crossbeam platforms are arranged perpendicular to the two linear guide rails and clamping rubber plates are installed on their upper surfaces.

[0012] As a further improvement of this utility model, two boss plates are arranged parallel to each other on the upper surface of the platform plate in the transverse direction. A rectangular groove is formed between the two boss plates, and bearing seats are provided at both ends of the groove. A positive and negative threaded rod is rotatably arranged between the two bearing seats. Two threaded rod nuts are engaged with the outside of the positive and negative threaded rod. The two threaded rod nuts are respectively engaged with one of the threads of the positive and negative threaded rod and connected to the bottom of one of the adjacent crossbeam platforms.

[0013] As a further improvement of this utility model, one end of the positive and negative threaded rod passes through the bearing seat and extends to the outside to be connected to a rotating handle.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Depend on Figure 1-3 Provided is an electronic circuit board processing and testing equipment for automotive ambient lights, including a horizontally arranged testing base 1; a mounting plate 2 is mounted on the upper surface of the testing base 1, and four support beams 3 are arranged in a rectangular distribution on the upper surface of the mounting plate 2, and a testing table 4 is mounted on the upper surface of the four support beams 3.

[0026] An electronic circuit board limiting component 5 is installed on the upper surface of the testing platform 4, and an electronic circuit board body 6 for automotive ambient lighting is mounted on the electronic circuit board limiting component 5.

[0027] The upper surface of the detection base 1 is supported by a vertical frame 7. The vertical frame 7 is vertically arranged and a connecting seat 8 is installed on its top side. A cylinder seat 9 is assembled on the side of the connecting seat 8. A first guide rod cylinder 10 is assembled inside the cylinder seat 9. The output end of the first guide rod cylinder 10 is vertically arranged and connected to a first visual inspection camera 11. The first visual inspection camera 11 is mounted vertically above the electronic circuit board limiting component 5.

[0028] In this embodiment, through the mutual movement and cooperation of multiple structures within the electronic circuit board limiting component 5, in actual use, the two sets of opposing sliding crossbeam platforms 54 can drive the clamping rubber plates 55 connected to them to achieve opposing clamping of electronic circuit board bodies 6 of different sizes for automotive ambient lights. This ensures that the electronic circuit board bodies 6 for automotive ambient lights are more stable during visual inspection after processing. At the same time, the precisely adjustable clamping force ensures the stability of the electronic circuit board bodies 6 for automotive ambient lights during the inspection process, and will not affect the test results due to vibration or movement, thereby improving the accuracy of visual measurement.

[0029] Furthermore, in the actual testing process, after the electronic circuit board body 6 for the automotive ambient lighting is manufactured, the first visual inspection camera 11 and the second visual inspection camera 13 work together to achieve precise visual inspection of the electronic circuit board body 6 for the automotive ambient lighting, thereby ensuring the stable use of the electronic circuit board body 6 for vehicle control. During this period, the compensation inspection by the first visual inspection camera 11 and the second visual inspection camera 13 enables more details on the electronic circuit board body 6 for the automotive ambient lighting to be captured from different directions, improving the defect recognition rate, such as poor soldering and component position deviation. At the same time, the tilted second visual inspection camera 13 can effectively reduce information loss caused by light reflection or shadows, thereby improving the overall image quality and measurement accuracy.

[0030] It should be noted that the first visual inspection camera 11 and the second visual inspection camera 13 are both existing mature structural components, their power connection methods are existing technologies, and the control circuits can be implemented by those skilled in the art through simple programming. They are common knowledge in the field, and are only used without modification. Therefore, the control methods and circuit connections will not be described in detail.

[0031] Specifically, refer to Figure 1-2 The side of the vertical frame 7 is provided with an installation groove, and the second guide rod cylinder 12 is installed at an angle in the installation groove. The output end of the second guide rod cylinder 12 is set at an angle and a second visual inspection camera 13 is installed at its end.

[0032] In this embodiment, during use, the mounting slot provided on the side of the vertical frame 7 can be used to install the second visual inspection camera 13; and the provided second visual inspection camera 13 can be used to perform compensated visual inspection on the electronic circuit board body 6 of the automotive ambient light, thereby cooperating with the first visual inspection camera 11 to achieve more accurate visual inspection.

[0033] Furthermore, during use, the user can also drive the second guide rod cylinder 12, connect the second guide rod cylinder 12 to an external air source, and give it a stable output air pressure value, so that the second vision detection camera 13 can operate linearly until it moves to the side of the electronic circuit board body 6 for the car ambient light, so that the second vision detection camera 13 can perform secondary visual compensation detection on the electronic circuit board body 6 for the car ambient light.

[0034] Specifically, refer to Figure 1-3The electronic circuit board limiting assembly 5 includes a platform plate 51 disposed on the upper surface of the detection table 4. Two linear guide rails 52 are arranged parallel to each other on the upper surface of the platform plate 51. Two guide rail sliders 53 are slidably disposed on each of the two linear guide rails 52. A crossbeam platform 54 is jointly supported on the upper surface of the two adjacent guide rail sliders 53. The two crossbeam platforms 54 are both arranged perpendicular to the two linear guide rails 52 and clamping rubber plates 55 are installed on their upper surfaces.

[0035] In this embodiment, the connection between the linear guide rail 52 and the guide rail slider 53, as well as the mutual connection between the guide rail slider 53 and the crossbeam platform 54, allows both crossbeam platforms 54 to move linearly along the travel range of the linear guide rail 52.

[0036] Specifically, refer to Figure 3 Two boss plates 56 are arranged parallel to each other on the upper surface of the platform plate 51. A rectangular groove is formed between the two boss plates 56, and bearing seats 57 are provided at both ends of the groove. A positive and negative threaded rod 58 is rotatably arranged between the two bearing seats 57. Two threaded rod nuts 59 are engaged with the outside of the positive and negative threaded rod 58. The two threaded rod nuts 59 are respectively engaged with one of the threads of the positive and negative threaded rod 58 and connected to the bottom of one of the adjacent crossbeam platforms 54.

[0037] In this embodiment, when the positive and negative threaded screw 58 rotates, it is limited by the connection between the linear guide rail 52 and the guide rail slider 53, and by the mutual connection between the screw nut 59 and the crossbeam platform 54, so that the two screw nuts 59 meshing on the outside of the positive and negative threaded screw 58 can drive the two crossbeam platforms 54 to move linearly.

[0038] Furthermore, during this period, when the positive and negative threaded screws 58 are rotating in the forward direction, the screw nuts 59 engaged with the outside of the positive and negative threaded screws 58 can drive the two crossbeam platforms 54 to move in opposite directions. Similarly, when the positive and negative threaded screws 58 are rotated in the reverse direction, the two screw nuts 59 can drive the crossbeam platforms 54 to move in opposite directions.

[0039] Specifically, refer to Figure 3 One end of the positive and negative threaded rod 58 passes through the bearing housing 57 and extends to the outside, where a rotating handle 510 is connected.

[0040] In this embodiment, the rotating handle 510 can be used to control the rotation direction of the positive and negative threaded rods 58, thereby achieving precise movement between the two crossbeam platforms 54.

[0041] Furthermore, the power connection method of the rotating handle 510 is existing technology, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the field. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0042] Specifically, refer to Figure 3 The upper surface of the platform plate 51 has four 511 arranged in a rectangular pattern, and the vertices of the four 511 are horizontally arranged with the upper surface of the crossbeam platform 54.

[0043] In this embodiment, the 511 is designed to work with the crossbeam platform 54 to support the bottom of the electronic circuit board body 6 for automotive ambient lighting, thereby ensuring the horizontal stability of the electronic circuit board body 6 for automotive ambient lighting during testing.

[0044] This utility model relates to a processing and testing equipment for electronic circuit boards used in automotive ambient lighting.

[0045] Step 1: In the actual processing operation, after the electronic circuit board body 6 for controlling the car ambient lighting equipment is manufactured, the user can transfer it to the electronic circuit board limiting component 5, thereby using the electronic circuit board limiting component 5 to clamp and limit the electronic circuit board body 6 for the car ambient lighting.

[0046] Step 2: After the electronic circuit board body 6 of the car ambient light is clamped by the electronic circuit board limiting component 5, the user connects the first guide rod cylinder 10 to an external air source and provides the first guide rod cylinder 10 with an output air pressure value, so that the first guide rod cylinder 10 can drive its output end to move vertically. Through the connection between the first guide rod cylinder 10 and the first vision detection camera 11, the user controls the output end of the first guide rod cylinder 10 to move, so that the first vision detection camera 11 is lowered to a suitable height until it is above the electronic circuit board body 6 of the car ambient light. Then the user can drive the first vision detection camera 11 to achieve visual detection of the electronic circuit board body 6 of the car ambient light.

[0047] Step 3: When the first visual inspection camera 11 is performing visual inspection on the electronic circuit board body 6 of the car ambient light, the user can also drive the second guide rod cylinder 12 to move the second visual inspection camera 13 to the side of the electronic circuit board body 6 of the car ambient light. The second visual inspection camera 13 will then perform secondary visual compensation inspection on the electronic circuit board body 6 of the car ambient light, thereby cooperating with the visual inspection of the first visual inspection camera 11 to further improve the accuracy of visual inspection of the electronic circuit board body 6 of the car ambient light.

[0048] Step 4: Through the cooperation of multiple structures within the electronic circuit board limiting assembly 5, the electronic circuit board limiting assembly 5 can clamp and limit the electronic circuit board body 6 of different sizes for automotive ambient lights. During this process, when the user adjusts the electronic circuit board limiting assembly 5, by rotating the rotating shaft handle 510, the positive and negative threaded rods 58 connected to the rotating shaft handle 510 can rotate synchronously. When the positive and negative threaded rods 58 rotate, they are limited by the connection between the linear guide rail 52 and the guide rail slider 53, as well as the connection between the threaded rod nut 59 and the crossbeam platform 54. The interconnection of the two screw nuts 59, which are engaged with the outside of the positive and negative screws 58, can drive the two crossbeam platforms 54 to move linearly. During this period, when the user rotates the shaft handle 510 in the forward direction, the two crossbeam platforms 54 can drive the clamping rubber plates 55 installed thereon to move in opposite directions to clamp the electronic circuit board body 6 of the car ambient light. Similarly, when the shaft handle 510 is rotated in the reverse direction, the two crossbeam platforms 54 can drive the clamping rubber plates 55 to separate in the opposite direction, thereby realizing the separation and release of the electronic circuit board body 6 of the car ambient light.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
