Technical Field
[0001] This utility model relates to the field of automotive lighting manufacturing technology, specifically to a testing mechanism that integrates locking, electrical inspection, and visual inspection functions. Background Technology
[0002] In the current assembly and testing process of automotive lights, automatic locking, electrical testing of lights, and visual inspection are the mainstream technologies. However, these technologies are often designed separately and implemented on different machines. This not only increases the cost of assembly and testing equipment and labor costs, but also increases the cycle time of the process and the factory layout area. Summary of the Invention
[0003] To address the time-consuming, labor-intensive, and costly technical problems caused by the separate design and multiple assembly processes required for automatic locking, electrical inspection of lamps, and visual inspection in existing technologies, this application proposes a testing mechanism that integrates locking, electrical inspection, and visual inspection functions, thus solving the aforementioned technical problems.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] This utility model provides a testing mechanism integrating locking, electrical inspection, and visual inspection functions, comprising: a frame, on which a fixing fixture for supporting lamps and a robotic arm for operating the lamps are mounted; a locking device, including a locking module mounted at the end of the robotic arm and a screw feeder mounted on the frame, wherein the automatic screwdriver of the locking module obtains a screw from the screw feeder via the robotic arm and moves to the corresponding position on the lamp to screw in the screw, thus connecting the various parts of the lamp; an electrical inspection device, including a current and voltage detection module mounted on the frame for detecting the current and voltage values of the lamp after it is powered on; and a visual inspection device, including a first visual inspection module mounted at the end of the robotic arm and a second visual inspection module mounted on the frame, wherein the first visual inspection module moves with the robotic arm to detect whether the wiring harness on the lamp is properly connected, and the second visual inspection module cooperates with the current and voltage detection module to detect the lighting effect of the lamp.
[0006] Furthermore, the fixing fixture includes: a fixed base plate connected to the frame, wherein a positioning block adapted to the shape of the lamp is fixed on the fixed base plate; a clamping assembly including a corner cylinder disposed on the fixed base plate and a pressing block controlled by the corner cylinder to press the lamp into place; and a laser sensor disposed on the fixed base plate near the clamping assembly to sense whether the lamp is pressed into place.
[0007] Furthermore, the fixed base plate is detachably connected to the frame via a rotating plunger.
[0008] Furthermore, the fixed base plate is also equipped with a pneumatic-electric coupler plug.
[0009] Furthermore, the robotic arm is equipped with a connecting bracket at its end.
[0010] Furthermore, the locking module also includes a vertical cylinder, the cylinder body of which is fixed on the connecting bracket, and the piston rod of which is connected to the automatic screwdriver so that the automatic screwdriver is pressed into the corresponding position of the lamp.
[0011] Furthermore, the locking module also includes: a guide slider, which is connected to and slidably fitted onto the connecting bracket of the vertical cylinder piston rod; and a buffer spring, one end of which is connected to the piston rod of the vertical cylinder, and the other end of which is fixedly configured to buffer the automatic screwdriver.
[0012] Furthermore, the locking module also includes a guide tube fixed on the connecting bracket, through which the bit of the automatic screwdriver passes to guide the bit.
[0013] Furthermore, the first visual inspection module is connected to the end effector of the robotic arm via the connecting bracket. The first visual inspection module includes: an industrial camera, which is detachably connected to the connecting bracket and has its lens arranged vertically downwards; and a light source, which is arranged on the connecting bracket and located below the lens of the industrial camera.
[0014] Furthermore, the frame is also equipped with a laser marking machine to mark the lamps being inspected.
[0015] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:
[0016] This utility model discloses a testing mechanism that integrates locking, electrical inspection, and visual inspection functions. The lighting fixture only needs to be assembled once to complete locking, electrical inspection, and visual inspection, thereby reducing the number of racks, reducing the site layout area, reducing the number of manual handling operations, reducing process steps, improving efficiency, and reducing costs. A robotic arm replaces manual operation, thus allowing for better control of the production cycle and avoiding the impact of human factors on the production cycle, greatly improving production efficiency. The locking module and the first visual inspection module at the end of the robotic arm move with the robotic arm. The automatic screwdriver in the locking module ensures the screws are securely fastened and that the corresponding positions of each part of the lighting fixture are consistent. To reduce the risk of missing screws, the first visual inspection module performs inspections simultaneously with the fastening process to ensure that the wiring harness on the lamp is properly connected, reducing the movement path of the robotic arm's end effector, optimizing cycle time, and improving efficiency. The current and voltage detection module on the frame works in conjunction with the second visual inspection module, both performing operations simultaneously. While ensuring that electrical inspection requirements are met, the lighting effect of the lamp is immediately inspected, such as the light pattern, brightness, and color of the lamp, improving the accuracy and efficiency of the inspection. This utility model's inspection mechanism not only integrates multiple technologies such as electrical inspection, automatic fastening, and visual inspection, but also solves problems such as batch consistency of incoming materials and structural versatility, and has profound research significance.
