Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle light testing technology, specifically relating to a plug-in tooling for DLP vehicle light illumination testing. Background Technology
[0002] In the automated production line for automotive lights, the DLP lighting test requires employees to manually connect the wiring harness. Only after the connection is completed can the button be pressed to perform the functional test. However, when connecting the wiring harness, employees have to reach into a narrow space and bend over to blindly insert it, which wastes operation time and causes the risk of loose connections, affecting the test results. If a loose connection causes the equipment to alarm, the problem needs to be investigated and the test needs to be reworked. After the test is completed, the wiring harness also needs to be manually unplugged. If the wiring harness is not unplugged, it will be pulled during automatic transfer, causing the wiring harness at that station to break and the wiring harness opening on the headlight to crack, thus rendering the headlight unusable. Utility Model Content
[0003] The purpose of this utility model is to address the defects and shortcomings of existing technologies by designing a simple, stable, and reliable DLP vehicle headlight illumination detection plug-in tooling that reduces risks, improves production efficiency, and saves manpower and resources.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a plug-in tooling for DLP vehicle headlight illumination detection, including a lamp video harness fixed by a lamp harness cover plate, and a vehicle body end harness that can telescopically move under the action of a slide cylinder. The vehicle body end harness can be plugged into or unplugged from the lamp video harness through telescopic movement, and a flexible correction mechanism is also provided between the vehicle body end harness and the lamp video harness.
[0005] Preferably, the slide cylinder is mounted on the cylinder fixing block, and the vehicle body end wiring harness is fixedly connected to the slide cylinder through the first wiring harness fixing block and the second wiring harness fixing block.
[0006] Preferably, the flexible correction mechanism includes a guide block slidably disposed between the vehicle body end wiring harness and the lighting video wiring harness, and a bushing disposed on the guide block corresponding to the lighting video wiring harness, wherein the sliding direction of the guide block is consistent with the extension and retraction direction of the vehicle body end wiring harness.
[0007] Preferably, a guide rail is provided at the bottom of the guide block, and the guide block slides with the guide rail via a slider.
[0008] Preferably, a guide shaft is provided between the guide block and the telescopic end of the slide cylinder, and a spring is provided on the guide shaft.
[0009] Preferably, the telescopic end of the slide cylinder is further provided with a positioning pin corresponding to the position of the slider.
[0010] After adopting the above technical solution, the plug-in tooling for DLP vehicle headlight illumination detection provided by this utility model has the following beneficial effects:
[0011] This invention utilizes a sliding cylinder design to automatically connect the vehicle body-side wiring harness to the lighting and video wiring harness, reducing the need for manual wiring and bending to check for proper connection. The equipment initiates a detection program to complete DLP projection testing, minimizing the number of alarms caused by incomplete connections and reducing rework time. Furthermore, it eliminates the need for manual harness unplugging, reducing damage and scrapping caused by missed connections. The flexible correction mechanism protects the lighting and video wiring harness interfaces. The use of linear guides and spring buffers corrects the automatically advancing harness while preventing rigid contact, improving production efficiency and reducing failure rates. Therefore, this invention offers advantages such as simple structure, stability, reliability, reduced risk, increased production efficiency, and savings in manpower and resources.

[0015] The present invention will now be described in further clear and complete detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0017] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0018] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.
