The automobile door handle detection, assembly and engraving equipment according to claim 2, characterized in that: The detection moving module G includes a mounting frame mounted on a large base plate (60), the mounting frame including a long base plate (77), a horizontal plate (76), an inclined support plate (75) and a column plate (74); a servo motor module 3 (73) with a ball screw is horizontally arranged on the top of the mounting frame, the servo motor module 3 (73) is vertically connected to the servo motor module 2 (70) with a ball screw through a screw connecting block 3 (72), and the servo motor module 2 (70) is connected to a screw connecting block 2 (71).

8. The automobile door handle detection, assembly and engraving equipment according to claim 7, characterized in that: The force detection assembly H comprises a small base plate (78) connected to the second screw rod connecting block (71), and an S-type tension and pressure sensor (80) is installed on the lower part of the small base plate (78) through a mounting block (81); a T-type detection probe (83) is slidably provided on the bottom of the small base plate (78) through a guide rail slider (82), and the upper part of the T-type detection probe (83) is connected to the S-type tension and pressure sensor (80).

9. The automobile door handle detection, assembly and engraving equipment according to claim 1, characterized in that: The engraving machine F is mounted on the large base plate (60) and includes an engraving machine lens (84).

10. The method for using the automobile door handle detection, assembly and engraving device according to any one of claims 1 to 9, characterized in that: The operation of the automobile door handle detection, assembly and engraving equipment includes the following steps: manually placing the automobile door handle into the fixture assembly, the paddle auxiliary mechanism D operates to prevent the paddle rotation shaft (7) of the automobile door handle from shaking, the fixed handle mechanism C fixes the automobile door handle and pushes the paddle to drive the handle internal spring (5) and the paddle rotation shaft (7) to rotate to the pre-detection position, and the paddle auxiliary mechanism D exits; the feeding module bottom plate assembly A moves the automobile 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, and the force value detection process is completed. After the force value is determined to be within a reasonable range, the paddle assembly E inserts the paddle boss (9) into the handle groove (10) for assembly, and the detection moving module G and the paddle assembly E exit; based on whether the force value is within a reasonable range, it is determined whether the handle is qualified; if it is unqualified, the feeding module bottom plate component A sends the car door handle to the material taking position; if it is qualified, the feeding module bottom plate component A sends the car door handle to the marking position to trigger the engraving machine F to engrave the handle number, and then the feeding module bottom plate component A moves the car door handle to the material position; the inspection, assembly and engraving of the car door handle are completed.
