Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Example: A car door handle inspection device. This device is used to implement the aforementioned automatic inspection, assembly, and engraving equipment for car door handles. (The door handle structure is referenced here.) Figure 1-2 As shown, the device is divided into a left handle and a right handle with symmetrical structure. Correspondingly, the device also provides two types of right clamp assembly and left clamp assembly with symmetrical structure.

[0019] In terms of the structure of this equipment, refer to Figure 3 , 6 As shown in Figure -15, the system includes a feeding module base plate assembly A, which includes a slidably mounted common base plate 62, on which a fixture assembly is mounted; the fixture assembly includes a fixture base plate assembly B, on which a fixed handle mechanism C, a paddle auxiliary mechanism D, and a paddle assembly E are mounted; the feeding module base plate assembly A is equipped with an engraving machine F and a detection moving module G, on which a force value detection assembly H is mounted.

[0020] When operating with the above equipment, the main steps are as follows: The car door handle is manually placed into the fixture assembly; the paddle auxiliary mechanism D operates to prevent the paddle rotation shaft 7 of the car door handle from shaking; the handle fixing mechanism C fixes the car door handle and pushes the paddle to rotate the internal spring 5 and the paddle rotation shaft 7 to the pre-detection position; the paddle auxiliary mechanism D then retracts; the feeding module base plate assembly A moves the car door handle to the detection position; the detection moving module G drives the force value detection assembly H to move to the paddle detection position 8 to detect the force value; after the force value detection is completed, the force value is judged. To determine if the force is within a reasonable range, the paddle assembly E engages the paddle boss 9 into the handle groove 10, and the moving module G and paddle assembly E are then disengaged. Based on whether the force value is within a reasonable range, the handle is judged to be qualified. If unqualified, the feeding module base plate assembly A moves the car door handle to the material pick-up position. If qualified, the feeding module base plate assembly A moves the car door handle to the marking position, triggering the engraving machine F to engrave the handle number. Then, the feeding module base plate assembly A moves the car door handle to the material position, completing the inspection, assembly, and engraving of the car door handle.

[0021] Furthermore, considering the following structure and working principle of this device, the working process of this utility model is as follows: The main working process of this utility model is: manually inserting the spring-loaded handle (refer to...) Figure 1-2 The handle is placed into the corresponding left and right handle clamps (12 or 16), specifically between support plate 19 and support plate 22. The handle is restricted to prevent it from moving back and forth. After starting, the paddle auxiliary mechanism D ( Figure 7 Move to the auxiliary position, the paddle rotation shaft 7 engages with the auxiliary push plate 26 to prevent shaft wobbling; fix the handle mechanism ( Figure 8 The fixed handle is moved, and the cylinder mounting plate (38, 42) is used to fix the handle on the side and make it shake. The pressing cylinder 45 presses down to make the fixed handle move. The pre-detection push cylinder 40 extends to push the handle's paddle, so that the paddle drives the handle's internal spring 5 and paddle rotation shaft 7 to rotate to the pre-detection position. The left and right movement cylinder 24 of the paddle auxiliary mechanism D retracts and resets to the initial position. Then, in the feeding module base plate assembly A, the servo motor module 63 drives the fixture assembly to move to the detection position. The servo motor module 70 drives the power value detection assembly H to move downward to the T-shaped detection probe 83 and the paddle detection position 8 at the same horizontal line. The servo motor module 73 moves the force value detection assembly H to the right so that the paddle detection position 8 contacts the T-shaped detection probe 83 and the detection begins. The servo motor module 73 moves to make the paddle rotate around the paddle rotation shaft 7, so that the paddle boss 9 ( Figure 4 ) and handle groove 10 ( Figure 5 When the servo motor module 373 stops at the same mating plane, the force value detection process is completed, and the PLC controller determines whether the force value is within a reasonable range; the paddle assembly E ( Figure 9In the process, the up-and-down moving cylinder 55 rises, and the assembly moving cylinder 48 moves to make the assembly top cylinder 53 and the handle paddle assembly top position 4 concentric. The assembly top cylinder 53 extends to move the paddle rotation shaft 7 so that the paddle boss 9 is engaged in the handle groove 10 to complete the assembly. The servo motor module three 73 retracts to the initial position, the paddle assembly body E retracts and resets to the initial state, the servo motor module two 70 retracts upward to the initial position, and all the cylinders of the fixture assembly body also reset to the initial position. It is judged whether the handle force value is qualified. If it is not qualified, the feeding module base plate assembly A sends the car door handle to the picking position. If it is qualified, the feeding module base plate assembly A will align the handle number engraving position 2 of the car door handle with the engraving lens 84 on the same vertical line, triggering the engraving machine to engrave. After the engraving is completed, the feeding module base plate assembly A moves outward to move the engraved car door handle to the picking position, thereby completing the inspection, assembly and engraving process of the car door handle.
