[0020] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not limiting of the scope of protection of this utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a stainless steel pen tip defect detection device based on machine vision, including an inspection machine 1. The inspection machine 1 is used to set corresponding components. The inspection machine 1 has an internal cavity. A conveyor belt 2 is fixedly installed inside the inspection machine 1 for conveying materials. A vision inspection robot 3 is fixedly installed on the top of the inspection machine 1 for detecting pen tip defects. Guide frames 4 are fixedly installed at both ends of the top of the conveyor belt 2 for guiding. Guide frames 4 are fixedly installed on both sides of the top of the inspection machine 1. A magnetic connecting rod 5 is provided, which is used to set the corresponding components. A cavity is opened at the bottom of the magnetic connecting rod 5. A guide rod 6 is provided at the bottom of the magnetic connecting rod 5. The guide rod 6 is used to set the rubber rod 7. The rubber rod 7 is fixedly installed at the bottom of the guide rod 6. The rubber rod 7 can limit the pen tip. The top of the guide rod 6 passes through the magnetic connecting rod 5 and extends into its interior. Pin grooves 8 are opened on both sides of the guide rod 6. The pin grooves 8 are used to cooperate with the locking pins 9. Locking pins 9 are provided at the bottom of both sides of the magnetic connecting rod 5. Locking pins 9 can limit the guide rod 6.

[0022] Furthermore, both ends of the conveyor belt 2 pass through the testing machine 1 and extend to its exterior, wherein the conveyor belt 2 is used to transport materials.

[0023] Furthermore, the guide rod 6 is movably connected to the magnetic connecting rod 5, wherein the guide rod 6 is used to set the rubber rod 7.

[0024] Furthermore, there are several pin slots 8, and each pair of pin slots 8 is designed to be equidistant from each other. The pin slots 8 are used to cooperate with the locking pins 9.

[0025] Furthermore, the two locking pins 9 each penetrate the magnetic connecting rod 5 on opposite sides and extend into the interior of the pin groove 8. The locking pins 9 engage with the pin groove 8 and are magnetically connected to the magnetic connecting rod 5. The locking pins 9 can limit the movement of the guide rod 6.

[0026] Furthermore, a support spring 10 is fixedly installed at the top of the guide rod 6, and the top end of the support spring 10 is fixedly connected to the top of the magnetic connecting rod 5. The support spring 10 can support the guide rod 6.

[0027] Furthermore, a cabinet door 11 is movably installed on the front surface of the testing machine 1, and a handle is fixedly installed on the front surface of the cabinet door 11, wherein the handle facilitates the user to open the cabinet door 11.

[0028] Working principle: When using this device, the user places the pen tip between the two guide frames 4 and makes the bottom of the pen tip contact the conveyor belt 2. Then, the user pulls the guide rod 6 to move the rubber rod 7, so that the bottom of the rubber rod 7 contacts the pen tip. After contact, the user uses the locking pin 9 to lock the rubber rod 7 in place with the pin groove 8, thereby limiting the position of the rubber rod 7. Then, when the user starts the conveyor belt 2 to feed the material, the pen tip will rotate under the action of the conveying force of the conveyor belt 2 and the friction force with the rubber rod 7. After that, the user starts the vision inspection robot 3 to perform an all-round inspection of the pen tip.

[0029] Based on the above work process, we can conclude that:

[0030] This machine vision-based stainless steel pen tip defect detection device, by setting up a guide frame 4, guide rod 6, rubber rod 7 and locking pin 9, enables the pen tip to rotate automatically while being conveyed on the conveyor belt 2 using friction, thereby reducing costs and enabling assembly line detection of pen tips, improving detection efficiency, bringing convenience to users, enhancing the practicality of the device, and meeting user needs.
