[0037] In one embodiment of this utility model, such as Figures 1-3 As shown, an automatic marking device for defects in plastic products is provided, including a moving mechanism 1, a lifting mechanism 2, a detection mechanism 3, and a marking mechanism 4. The lifting mechanism 2 is connected to the moving mechanism 1, the detection mechanism 3 is connected to the lifting mechanism 2, and the marking mechanism 4 is connected to the detection mechanism 3.
[0038] The moving mechanism 1 includes a moving cylinder 11, a moving connecting plate 12, a moving slider 13, a moving slide rail 14, and a moving slide base 15. The moving connecting plate 12 is fixedly connected to the moving cylinder 11 and the moving slider 13 respectively. The moving slider 13 is slidably connected to the moving slide rail 14 and fixedly connected to the moving slide base 15. The moving slide rail 14 is fixedly connected to the moving cylinder 11. Through the extension and retraction movement of the moving cylinder 11, the moving connecting plate 12 is driven, thereby causing the moving slider 13 to slide on the moving slide rail 14, realizing the horizontal movement of the entire device to meet the inspection and marking needs of plastic products in different positions.

The controller 33 analyzes and processes the images according to a preset detection program to determine whether there are defects in the plastic product. When a defect is detected, the controller 33 controls the lifting cylinder 22 to work, causing the marking mechanism 4 to descend to a suitable position for marking.
[0041] The marking mechanism 4 includes a marking base 41, a marking plate 42, and a marking pen 43.

[0045] In another embodiment of the present invention, the lifting cylinder 22 includes a lifting cylinder body 221 and a lifting piston rod 222.

[0046] In another embodiment of this utility model, the lifting connecting plate 23 is L-shaped and is fixedly connected to the lifting piston rod 222 and the detection fixing plate 31 respectively. The L-shaped lifting connecting plate 23 facilitates connection with the detection fixing plate 31 and the lifting piston rod 222, while ensuring the stability of the connection.
[0047] In another embodiment of this utility model, a detection limiting plate 34 is fixedly connected to the bottom side of the detection fixing plate 31. The detection limiting plate 34 has a detection limiting hole 341 in the middle, and the bottom end of the CCD 32 passes through the detection limiting hole 341. The detection limiting plate 34 and the detection limiting hole 341 can position and fix the CCD 32, ensuring the positional accuracy of the CCD 32 during the detection process.
[0048] In another embodiment of this utility model, the marking fixing plate 42 and the detection fixing plate 31 are arranged parallel and spaced apart. The marking fixing plate 42 has a marking fixing groove 421 in the middle, and the marking pen 43 is installed in the marking fixing groove 421 and fixedly connected to the marking fixing plate 42. The parallel and spaced marking fixing plate 42 and the detection fixing plate 31 enable the marking mechanism 4 and the detection mechanism 3 to work independently yet collaboratively. The marking fixing groove 421 facilitates the installation and removal of the marking pen 43.
[0049] In another embodiment of this utility model, a marking limiting plate 44 is fixedly connected to the bottom side of the marking fixing plate 42.

[0050] The automatic defect marking device for plastic products provided in this application operates as follows:
[0051] When it is necessary to inspect and mark defects in plastic products, the moving cylinder 11 is activated, the moving piston rod 112 extends and retracts to drive the moving connecting plate 12, so that the moving slider 13 slides on the moving slide rail 14, thereby moving the entire device to a suitable position above the plastic product.
[0052] Next, the lifting cylinder 22 is activated, and the lifting piston rod 222 extends and retracts, driving the lifting connecting plate 23 to lower the detection mechanism 3 and the marking mechanism 4 to a position close to the surface of the plastic product. At this time, the CCD 32 begins to acquire images of the surface of the plastic product and transmits the acquired image information to the controller 33 in real time.
[0053] The controller 33 analyzes and processes the image. When it is determined that there is a defect on the surface of the plastic product, the controller 33 controls the lifting cylinder 22 to work again, so that the marking mechanism 4 descends further until the marking pen 43 contacts the position of the defect on the surface of the plastic product, and then the marking pen 43 marks the position of the defect.
[0054] After marking is completed, the controller 33 controls the lifting cylinder 22 to drive the detection mechanism 3 and the marking mechanism 4 to rise and reset. Then the moving cylinder 11 works to move the device above the next plastic product to be tested, and repeats the above detection and marking process.
[0055] The automatic marking device for plastic product defects provided in this application has a marking mechanism 4 and a detection mechanism 3 that are set independently. When it is necessary to replace the marking pen 43, the marking pen 43 can be easily replaced simply by removing the marking fixing plate 42 without disassembling the CCD 32. This improves the convenience of replacing the marking pen 43, reduces the difficulty of operation and time cost, avoids the damage that may be caused by frequent disassembly of the CCD 32, ensures the detection accuracy and service life of the CCD 32, and improves the accuracy and stability of the device's detection results.
[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
