However, existing equipment still suffers from insufficient inspection accuracy, decreased inspection accuracy after repeated operation, and low inspection efficiency. Utility Model Content

[0031] Furthermore, in the description of this utility model, unless otherwise stated, "multiple", "multiple groups", and "multiple roots" mean two or more.

[0032] Unless otherwise specified, the materials, instruments and methods used in the following embodiments are all conventional materials, instruments and methods in the art and can be obtained through commercial channels.

[0033] Example 1

[0034] like Figure 1 , Figure 2 The schematic diagram of the overall structure of this utility model shows that the lock CCD size detection device includes a detection platform 1, a turntable 2, a detection frame 3, and a CCD detection component 4 mounted on the detection frame 3. Mounting holes are pre-drilled on the detection platform 1, turntable 2, and detection frame 3. The fixing points of the detection frame 3 are located on the detection platform 1 and turntable 2. The components of the CCD detection component 4 have connecting holes for fixing, allowing the CCD detection component to be modularly assembled and disassembled. The CCD detection component 4 includes an XY movement device 5 mounted on the detection frame 3, wherein the XY movement device 5 includes an X-direction movement module 51 and a Y-direction movement module 52, and a CCD detection camera 6 is mounted on the Y-direction movement module 52. The turntable 2 includes a fixed inner plate 11 and a movable outer plate 12. The movable outer plate 12 is provided with 6-8 inspection stations 13. Inspection fixtures 14 are installed at the inspection stations 13. The fixed inner plate 11 is provided with a positioning fixture 8 with a fixed lock at the inspection station 13. The turntable 2 and the CCD inspection component 4 are both connected to a Siemens PLC control device.

[0035] like Figure 3As shown, the X-direction moving module 51 comprises: a connecting plate 511 on one side of the detection frame 3; a lead screw module 512 and a slide rail 513 aligned parallel to each other on the connecting plate 511; limit blocks at both ends of the lead screw module 512; a servo motor 518 connected to one end of the lead screw module 512; a first slider 514 and a second slider 515 at the same horizontal height on the lead screw module 512 and the slide rail 513; a moving frame 516 vertically mounted on the first slider 514 and the second slider 515; a chain groove on the top of the detection frame 3; and a plastic chain 517 for mounting cables continuously arranged on the top of the moving frame and the chain groove. The lead screw module enables high-precision and stable movement in the X direction, significantly improving displacement control accuracy. In addition, by aligning the sliders, the moving frame connected to the sliders is stably translated, avoiding errors in the detection results caused by repeated operation and movement of the moving frame.

[0036] like Figure 4 As shown, the Y-direction moving module 52 is fixed below the moving frame 516. The Y-direction moving module includes a first connecting block 521 disposed below the moving frame, a horizontal movement cylinder 522 connected below the first connecting block, a second connecting block 523 connected below the horizontal cylinder, a vertical third connecting block 525 connected to the second connecting block through a right-angle reinforcing member, and a connecting seat 526 for fixing the CCD detection camera 6 fixedly connected to the third connecting block. The arrangement of multiple connecting blocks ensures a tight connection between the moving frame and the functional components, preventing deviation during CCD camera movement. Furthermore, the modular connection, simple material structure, and ease of installation and connection reduce maintenance costs.

[0037] The connecting base is also fixed with an upper ring light device 15 that is fitted onto the lens of the CCD inspection camera. A strip backlight device 16 is set below the corresponding inspection station 13. The upper ring light device uses multi-angle uniform illumination, which can effectively eliminate the interference of reflection on the metal surface of the lock. The strip backlight device below the inspection station provides a uniform backlight source, highlights the outline edge of the workpiece, and avoids shadow occlusion. Combined with the high-resolution imaging of the CCD camera, it can reduce the dimensional measurement error and improve the inspection effect.

[0038] like Figure 5 As shown, the positioning fixture 8 includes a lifting electric cylinder 81 installed on the fixed inner plate 11. A vertical plate 82 is installed next to the lifting electric cylinder 81. A positioning bracket 83 is provided at the end of the lifting electric cylinder. A threaded clamping member 84 is provided at the end of the positioning bracket. A baffle 85 is provided above the end of the electric cylinder on the vertical plate 82. A limiter 87 is provided on the baffle. Here, a hydraulic buffer is selected as the limiter. A T-shaped block 86 is stably connected to the top of the positioning bracket. The positioning fixture can stably clamp the lock to be tested, prevent the lock to be tested from shifting during operation, and reduce the testing accuracy.

[0039] like Figure 6As shown, the connection between the testing frame and the turntable and testing table is provided with a base adjustment device 23 that matches the mounting hole. The fixed adjustment device 23 is provided with a horizontal adjustment shaft 24. The base adjustment device provides millimeter-level offset correction for the testing frame, thereby improving the testing accuracy.

[0040] This invention does not improve any software programs or methods. This invention only designs the structure of the detection device. The methods or software programs involved in the debugging and control of the PLC control device and related sensors are all based on existing methods or software program design books, manuals and product manuals by those skilled in the art, combined with the functions involved in the principles and effects of this invention, and can be implemented by writing their own programs.

Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
