Description

Technical Field

[0001] This utility model relates to the field of automotive lamp grinding and drilling inspection technology, specifically to a tooling for post-grinding and drilling inspection of automotive lamps. Background Technology

[0002] Grinding and drilling are key processing steps in the automotive headlight manufacturing process. The grinding process is used to precisely machine the surface of the headlight housing or optical components to achieve the required surface finish, shape accuracy, and optical performance. The drilling process, on the other hand, is to machine holes of specific sizes and positions on the headlight components for subsequent assembly, fixing, or functional requirements. Both processes directly affect the assembly accuracy and performance of the headlight, so quality inspection after grinding and drilling is crucial.

[0003] Currently, the inspection of automotive lights after grinding and drilling is mostly done manually by sampling, which has the problems of strong subjectivity and high missed inspection rate, and it is difficult to meet the full inspection requirements of mass production. While single-station semi-automatic inspection introduces inspection equipment, it usually requires manual loading and positioning, and can only complete the inspection of a limited number of items at a time. For multi-dimensional inspection requirements (such as hole diameter, hole depth, surface defects, etc.), the workpiece needs to be moved multiple times, which not only results in low inspection efficiency, but also easily causes errors due to repeated positioning, leading to unstable inspection accuracy, and cannot meet the requirements of modern automotive light production lines for efficient and accurate inspection. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Automotive headlight grinding and drilling is a general term for the two processing steps of grinding and drilling in automotive headlight manufacturing. Grinding is used to process the surface of the headlight housing or optical components to achieve the required surface accuracy, shape accuracy and optical performance, such as improving the light refraction effect of the lens or making the housing surface smooth and flat. Drilling is to process holes for various purposes on the headlight components for subsequent assembly or functional operations, such as installing fixing screws or enhancing heat dissipation. These two processes work together, and grinding is usually done first and then drilling to ensure the quality and performance of the headlight.

[0031] Example 1:

[0032] Please see Figures 1 to 7 This utility model provides a technical solution:

[0033] A tooling for inspecting automotive headlights after grinding and drilling, comprising:

[0034] The full inspection frame 1 is provided with a cable chain groove 101 and a cylinder mounting groove 102. The cable chain groove 101 is used to accommodate and organize the cable cable chain 406, and the cylinder mounting groove 102 is used to adapt and install the drive cylinder. The full inspection frame 1 is provided with a fixed bracket 3 and a tooling tray assembly 2.

[0035] The fixed bracket 3 is fixedly connected to the left side of the upper end face of the full inspection frame 1, and the tooling tray assembly 2 is located on the right side of the upper end face of the full inspection frame 1.

[0036] The tooling pallet assembly 2 includes a movable bracket 4. Wedge block clamping assemblies are respectively provided on both sides of the upper end face of the movable bracket 4 and the fixed bracket 3. Roller grooves 401 and positioning pin holes 402 are provided on the movable bracket 4 and the fixed bracket 3. A directional roller assembly 5 is provided below the roller groove 401. A tooling positioning pin 405 is fixedly connected below the positioning pin hole 402.

[0037] Specifically, the directional roller assembly 5 includes a steel beam 501, which is fixedly connected to the lower end face of the movable bracket 4 and the fixed bracket 3 by a bracket. A diaphragm cylinder 504 is fixedly connected to the lower end of the steel beam 501. A roller seat 502 is fixedly connected to the upper end face of the output end of the diaphragm cylinder 504 by a connecting rod. A roller 503 is rotatably connected inside the roller seat 502.

[0038] The preferred diaphragm cylinder is the EV-20_120-5 diaphragm clamping cylinder.

[0039] Specifically, the tooling positioning pin 405 is fixedly connected to the lower end face of the movable bracket 4 and the fixed bracket 3 by a bracket. The tooling positioning pin 405 is driven by a cylinder and passes through the positioning pin hole 402 to reach the other side of the movable bracket 4 and the fixed bracket 3.

[0040] In this embodiment, after the vehicle headlight to be tested is processed by grinding and drilling, it is sent to the entrance of the testing fixture by a robot arm. The diaphragm cylinder 504 in the directional roller assembly 5 is activated, driving the roller seat 502 to rise, so that the roller 503 passes through the roller groove 401 of the movable bracket 4 and the fixed bracket 3, and the top surface reaches the top of the bracket. The robot arm places the vehicle headlight on the upper surface of the movable bracket 4 and contacts the roller 503. The roller 503 reduces the friction between the workpiece and the bracket. Subsequently, the fixture positioning pin 405 is driven by the cylinder to rise from below the positioning pin hole 402 and accurately insert into the positioning hole at the bottom of the vehicle headlight, so that the vehicle headlight can be positioned.

[0041] Specifically, the wedge clamping assembly includes a wedge block 409, the bottom of which is fixedly connected to the output end of the wedge cylinder 408. The wedge cylinder 408 is fixedly connected to the rear end of the mounting base 411. The wedge block 409 passes through the mounting base 411 to reach the other side of the mounting base 411. The mounting base 411 is fixedly connected to both sides of the movable bracket 4.

[0042] In this embodiment, after the vehicle lamp is positioned by the tooling positioning pin 405, the wedge cylinder 408 in the wedge clamping assembly is activated. Its output end pushes the wedge block 409 through the mounting base 411 along the guide structure of the mounting base 411 and close to both sides of the vehicle lamp until the wedge block 409 is in close contact with the surface of the vehicle lamp. The lateral clamping force generated by the wedge structure is used to firmly fix the vehicle lamp on the movable bracket 4 or the fixed bracket 3, so as to avoid the vehicle lamp from being displaced due to external vibration or the movement of the movable bracket 4 during the testing process, and to ensure the stability of the vehicle lamp position and the consistency of the testing benchmark during the testing process.

[0043] Specifically, the lower end face of the movable bracket 4 is slidably connected to the guide rail 404 on both sides via connecting sliders 407, and the lower end face of the movable bracket 4 is slidably connected to the rodless cylinder 403 via a slider of rodless cylinder 403. The rodless cylinder 403 drives the movable bracket 4 to move linearly on the guide rail 404.

[0044] Specifically, a cable chain 406 is fixedly connected to the lower end face of the movable bracket 4, and the cable chain 406 is installed in the cable chain groove 101.

[0045] In this embodiment, after the rodless cylinder 403 is activated, the slider of the rodless cylinder 403 drives the movable bracket 4 to move linearly along the guide rail 404. During the movement, the drag chain 406 on the lower end face of the movable bracket 4 moves synchronously with it, and the cables and air pipes in the drag chain groove 101 are neatly stored to avoid tangling or damage. When the movable bracket 4 is docked with the fixed bracket 3, the rodless cylinder 403 stops moving. Multiple inspection areas are sequentially set above the full inspection frame 1 along the movement trajectory of the movable bracket 4. Each inspection area is equipped with a separate sensor and inspection camera to form a complete inspection system. In the same testing area, when the moving bracket 4 moves linearly along the guide rail 404 under the drive of the rodless cylinder 403, it can drive the vehicle lights to be tested carried on it to enter each testing area in sequence, realizing the automation of testing. The fixed bracket 3 is also equipped with a wedge clamping component and a tooling positioning pin 405. When the moving bracket 4 moves the vehicle lights to the corresponding position of the fixed bracket 3, the pin can accurately dock and position them. With the wedge clamping, the vehicle lights are fixed in the fixed testing position for a second time, and the vehicle lights are kept stable in projects that require long-term or high-precision testing.

[0046] The preferred sensors are Keyence LK-G series laser displacement sensors and Omron ZX-L series laser sensors, used to detect dimensional parameters such as hole diameter, hole depth, and hole position deviation after drilling of the vehicle headlights. The preferred detection cameras are Cognex In-Sight series and Hikvision MV-CA series industrial cameras, which, together with a ring light source, are used to identify appearance defects such as scratches, burrs, and chipping caused by drilling on the surface of the vehicle headlights. These devices are mounted on the brackets above the support frame via separate brackets. The brackets are precisely arranged to correspond to the detection areas of the fixed bracket 3 and the movable bracket 4, ensuring that the detection direction of the detection element is directly facing the drilled part of the vehicle headlight and the surface to be inspected. The connection and installation method of the brackets is common industry practice and has been disclosed in existing technology, so it will not be elaborated here.

[0047] Specifically, the movable bracket 4 and the fixed bracket 3 are fixedly connected to the left side with an air-insertion assembly 6 and to the right side with a connector 410.

[0048] In this embodiment, the housing of connector 410 is preferably an H48B series connector 410 metal housing (e.g., H48B-AG-LB) with multiple sets of HA series ferrules (e.g., HA-010-F) installed inside. The specific selection can be made according to the sensor and detection camera models. Its installation and connection are common industry knowledge and have been disclosed in the prior art, so there is no need to elaborate here. Connector 410 is mainly used to provide stable power supply to the sensor and detection camera installed on the bracket, and at the same time realize the signal transmission between the detection equipment and the control system, including the vehicle headlight size data collected by the sensor (such as the drill hole diameter and hole position coordinates), the appearance image information captured by the camera, etc. Through the independent paths of multiple sets of ferrules inside, it is ensured that the power supply and signal transmission do not interfere with each other, and the real-time performance and accuracy of the detection data are guaranteed.

[0049] Specifically, the pneumatic connector assembly 6 includes a vertical clamp 601, which is fixedly connected to both sides of the pneumatic connector 602 via a connecting plate and bolts. The pneumatic connector is fixedly connected to the top of the Z-shaped bracket 603, which is fixedly connected to the left side of the upper end face of the movable bracket 4 and the fixed bracket 3. The vertical clamp 601 is preferably a Jiagang CH-101-B, and the pneumatic connector 602 is preferably an SMC KDM20-04 pneumatic plug.

[0050] An air tank is fixedly connected inside the full inspection frame 1. The air tank is preferably a Shende 40L air tank. It is connected to the air plug assembly 6 through pipelines to provide a stable air source reserve for the pneumatic actuators such as the wedge cylinder 408 and diaphragm cylinder 504 connected to the air plug assembly 6. This ensures that the pneumatic actuators respond quickly and have stable pressure during the inspection process, meeting the clamping force requirements of the wedge clamping assembly and the lifting accuracy of the directional roller assembly 5. The full inspection frame 1 is equipped with an inspection door and an electrical mounting plate. The electrical mounting plate of the full inspection frame 1 integrates a power supply. The power module is connected to the connector 410 on the right side through a cable to provide power support with the appropriate voltage for the electrical equipment such as the sensors and inspection cameras connected to the connector 410.

[0051] Example 2:

[0052] This utility model provides a technical solution that is basically the same as that in Embodiment 1, with slight differences.

[0053] When the item to be inspected is singular, the fixed bracket 3 can serve as an independent inspection station. The robotic arm can deliver the vehicle headlight to the station on the mobile bracket 4 for inspection, or it can deliver the vehicle headlight directly to the inspection station on the fixed bracket 3. After the wedge clamping component and tooling positioning pin 405 are used to fix it, the inspection can be completed. This forms a parallel inspection mode with the mobile bracket 4. The parallel operation of the two stations effectively reduces the inspection waiting time for a single product, especially in batch inspection scenarios, thereby improving the overall inspection efficiency.

[0054] In use, the vehicle headlight to be inspected is ground and drilled, then moved to the inspection fixture entrance by a robotic arm. The diaphragm cylinder 504 of the directional roller assembly 5 drives the roller 503 to rise, guiding the vehicle headlight to be placed on the movable bracket 4 or the fixed bracket 3. The fixture positioning pin 405 raises to position the vehicle headlight, and the wedge clamping assembly clamps it. The movable bracket 4 moves along the guide rail 404 under the drive of the rodless cylinder 403, causing the vehicle headlight to pass through each inspection area in sequence. The laser sensor detects the dimensional parameters, and the industrial camera identifies appearance defects. The inspection data is transmitted to the control system via the connector 410. After the inspection is completed, all clamping and positioning components are reset, and the vehicle headlight is picked up and sent out by the robotic arm.

[0055] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0056] 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.
