Description

Technical Field

[0001] The utility model relates to the technical field of quality inspection of automobile headlights, and particularly relates to a quality inspection device for the production of matrix automobile headlights. Background Art

[0002] Matrix automobile headlights form multiple lighting zones by integrating multiple LED lamp beads, and each zone can be independently controlled, so as to achieve precise control of light. Matrix automobile headlights are widely used in various scenarios requiring high-precision lighting, such as night driving, curve lighting, lighting under bad weather conditions, etc. As an important part of a vehicle, the performance of matrix automobile headlights directly affects the night driving safety and visual comfort of drivers. Using a quality inspection device can check whether there are appearance defects such as breakage, scratches, and deformation on the headlights. If there are defects on the appearance, such as lens breakage and reflector deformation, it may affect the lighting effect of the headlights, resulting in light scattering, insufficient brightness, or glare, thus affecting driving safety. Therefore, appearance quality inspection is an important link to ensure the lighting effect of the headlights, which can ensure that every detail of the headlights meets the design requirements, thus guaranteeing the overall quality and consistency of the product.

[0003] In existing detection devices, most detectors are directly exposed, and impurities such as dust and water vapor may adhere to key parts such as the probes and lenses of the detectors, which will accelerate the wear of the detectors, shorten their service life, and thus affect the accuracy and stability of the measurement results.

[0004] For example, a surface detection device for automobile stretch parts disclosed in the patent with the publication number of CN211292616U. The camera in this patent does not have a protection mechanism. After long-term use, impurities such as dust and metal chips are likely to adhere to the camera lens, affecting the shooting clarity, and further affecting the accuracy of the detection results. Moreover, the surface of the exposed camera is easily rubbed against surrounding objects. In the long run, it will cause surface scratches or wear, which will not only further affect the shooting quality but also shorten its service life and increase the maintenance cost.

[0005] Therefore, it is very necessary to invent a quality inspection device for the production of matrix automobile headlights to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a quality inspection device for the production of matrix automobile headlights to solve the problem of the lack of a lens protection function in the technology.

[0007] To achieve the above object, the present utility model provides the following technical solution: A quality inspection device for matrix automotive headlights production, including a machine body, a detector, and a protective cover. A display is provided on the front side wall of the machine body. A bracket is fixedly installed directly above the machine body. A cylinder is provided on the top surface of the bracket. The output end of the cylinder is installed with a detector. Thrust rods are provided on the left and right sides of the detector. A protective cover is provided outside the detector. Fixed rods are installed on the outer walls of the left and right sides of the protective cover. The side wall of the fixed rod is fixedly installed with the side wall of the bracket. The bottom surface of the protective cover is hinged with a cover plate. A test bench is provided above the machine body.

[0008] Preferably, the device includes two displays and two detectors. Each display is electrically connected to one detector respectively, and each display directly corresponds to one detector, which is convenient for the operator to monitor the detection conditions of two headlights simultaneously and improve the detection efficiency.

[0009] Preferably, an observation window is provided on the front side wall of the protective cover. The observation window is made of transparent glass material, allowing the operator to observe the placement of the detector inside the protective cover without opening the protective cover.

[0010] Preferably, springs are connected between the top surface of the cover plate and the inner wall of the protective cover. There are 4 springs, and the four springs are centrosymmetric with respect to the protective cover. Through the buffering effect of the springs, the collision force between the cover plate and the protective cover when the cover plate is closed is reduced.

[0011] Preferably, there are 2 cover plates. Magnets are provided on the contact surfaces of the two cover plates. There are 2 magnets, and the two magnets attract each other. Using the attractive force of the magnets, the two cover plates can be automatically aligned and closely fitted when closed, enhancing the sealing performance of the protective cover.

[0012] Preferably, there are 2 test benches. The two test benches are centrosymmetric with respect to the machine body. The test benches are arranged directly below the detectors. The double test benches correspond to the double detectors, realizing the simultaneous detection of two headlights and further improving the detection efficiency.

[0013] Preferably, a first warning light and a second warning light are provided on the front side walls of the two test benches. The first warning light and the second warning light are electrically connected to the detector. Through warning lights of different colors, the detection results are visually fed back to the operator.

[0014] Preferably, vertical plates are provided on the front and rear side walls of the test bench. Hydraulic rods are provided on the side walls of the vertical plates. Clamping plates are provided at the front and rear ends above the test bench. The side walls of the clamping plates are connected to the output ends of the hydraulic rods. The hydraulic rods are used to drive the clamping plates to automatically clamp the headlights to be tested, ensuring the stability and position accuracy of the headlights during the detection process.

[0015] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0016] 1. Through the settings of the protective cover and the cover plate, the protective cover and the cover plate can provide a physical barrier for the detector, preventing it from being damaged by external forces such as collision, scratching, and extrusion. When the detector is not in use, the detector is stored inside the protective cover to be isolated from the external environment, preventing harmful substances such as dust, water vapor, and corrosive gases from entering the inside of the detector, thereby protecting the internal precision components from pollution and erosion and providing a relatively stable storage environment for the detector;

[0017] 2. The lifting action of the detector and the opening and closing action of the cover plate are linked through the ejector rod and the spring, without manual intervention, improving the automation degree and the convenience of use of the device. When the detector needs to work, it can quickly and accurately expose the lens to ensure the smooth progress of the detection task; after the work is completed, it can quickly be stored back inside the protective cover to achieve rapid switching and efficient utilization.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the drawings.

[0026] The present utility model provides as Figures 1-5A quality inspection device for the production of matrix automotive headlights shown in the figure includes a machine body 1, an inspection instrument 5, and a protective cover 7. A display 2 is provided on the front side wall surface of the machine body 1. The device includes two displays 2 and two inspection instruments 5. Each display 2 is electrically connected to an inspection instrument 5. A bracket 3 is fixedly installed directly above the machine body 1. A cylinder 4 is provided on the top surface of the bracket 3. The output end of the cylinder 4 is equipped with an inspection instrument 5. Push rods 6 are arranged on the left and right sides of the inspection instrument 5. A protective cover 7 is arranged outside the inspection instrument 5. Fixed rods 8 are installed on the outer walls on the left and right sides of the protective cover 7. The side wall of the fixed rod 8 is fixedly installed with the side wall of the bracket 3. The bottom surface of the protective cover 7 is hinged with a cover plate 10. A test bench 13 is arranged above the machine body 1.

[0027] An observation window 9 is provided on the front side wall surface of the protective cover 7. The observation window 9 is made of transparent glass material. A spring 11 is connected between the top surface of the cover plate 10 and the inner wall of the protective cover 7. There are 4 springs 11. The four springs 11 are centrally symmetric with each other with respect to the protective cover 7. There are 2 cover plates 10. Magnets 12 are arranged on the contact surfaces of the two cover plates 10. There are 2 magnets 12. The two magnets 12 attract each other.

[0028] The two cover plates 10 on the bottom surface of the protective cover 7 are connected by springs 11. The setting of the springs 11 plays a role in buffering and automatic reset. When the cover plate 10 is opened, the spring 11 will be compressed; when the cover plate 10 is released, the elastic force of the spring 11 will help the cover plate 10 to automatically reset and fit tightly with the protective cover 7, thus maintaining the sealing performance of the protective cover 7. At the same time, magnets 12 are respectively installed on the contact surfaces of the two cover plates 10, and the two magnets 12 attract each other. The mutual attraction of the magnets 12 enhances the closing tightness of the cover plate 10. At the same time, the magnets 12 also simplify the closing operation of the cover plate 10. Just bring the cover plate 10 close and it will be automatically adsorbed and closed, improving the convenience of operation.

[0029] There are 2 test benches 13. The two test benches 13 are centrally symmetric with each other with respect to the machine body 1. The test benches 13 are arranged directly below the inspection instruments 5. No. 1 warning lights 14 and No. 2 warning lights 15 are arranged on the front side wall surfaces of the two test benches 13. The No. 1 warning lights 14, No. 2 warning lights 15 are electrically connected to the inspection instruments 5. Vertical plates 16 are arranged on the front and rear end side walls of the test benches 13. Hydraulic rods 17 are arranged on the side walls of the vertical plates 16. Clamping plates 18 are arranged at the front and rear ends above the test benches 13. The side walls of the clamping plates 18 are connected to the output ends of the hydraulic rods 17.

[0030] The design of the two test benches 13 allows for the simultaneous detection of two headlamps, improving the detection efficiency. The first warning lamp 14 and the second warning lamp 15 are respectively used to indicate the test results. For example, when the green light is on, it means qualified, and when the red light is on, it means unqualified. Through electrical connection, synchronous feedback with the detector 5 is achieved. This intuitive warning method helps the operator quickly identify the test results and take corresponding handling measures. The hydraulic rod 17 is set to drive the clamping plate 18 to automatically clamp the headlamp to be tested, ensuring the stability and position accuracy of the headlamp during the test. This automated design reduces the possibility of manual intervention and misoperation, improving the accuracy and reliability of the test results.

[0031] Working principle of the utility model:

[0032] Refer to the attached instruction manual Figures 1-5 When using the utility model, first place the two headlamps to be tested on the two test benches 13 in sequence, and then start the hydraulic rod 17. The hydraulic rod 17 drives the clamping plate 18 to automatically clamp the headlamp to be tested. After the position of the headlamp is fixed, the air cylinder 4 can be started. The air cylinder 4 drives the detector 5 to descend. When the detector 5 descends, the ejector rods 6 on both sides descend synchronously and first contact the cover plate 10. Thus, the ejector rods 6 apply a downward pressure to the cover plate 10, causing the two cover plates 10 to simultaneously flip downward and open, allowing the detector 5 to descend to expose and start detecting the appearance quality of the headlamp, and transmit the detection data to the display 2. The display 2 displays the detection data and results in real time, and at the same time lights the corresponding first warning lamp 14 and second warning lamp 15 according to the detection results. If the green light of the first warning lamp 14 is on, it proves that the headlamp is a qualified product. If the red light of the second warning lamp 15 is on, it means that the headlamp is an unqualified product and needs to be marked for repair.

[0033] After the appearance quality detection of the headlamp is completed and the detector 5 is no longer needed, the air cylinder 4 starts to move in the reverse direction, driving the detector 5 to rise. At the same time, the ejector rods 6 on both sides also rise synchronously. Since the ejector rods 6 no longer apply a downward pressure to the cover plate 10, the cover plate 10 starts to flip upward and gradually close the protective cover 7 under the action of the spring 11. When the two cover plates 10 approach, the magnets 12 will attract each other, further enhancing the sealing performance and stability of the cover plate 10. Thus, the closing of the protective cover 7 and the cover plate 10 protects the detector 5 from interference and damage from the external environment, helping to extend the service life of the detector 5.
