[0002] In modern manufacturing, marking and inspection processes are crucial for ensuring product quality and traceability. Traditional manual marking methods are inefficient and prone to errors. While simple mechanical marking methods improve efficiency, they still suffer from inaccurate marking, mismarking, and difficulty in achieving comprehensive automated inspection. With the development of automation technology, automatic marking and inspection machines have gradually become indispensable equipment in the production process. These machines integrate advanced optical recognition and mechanical positioning technologies, enabling them to quickly and accurately mark products and perform real-time inspection of the marking quality, greatly improving production efficiency and product quality.

[0003] However, when using traditional automatic marking and inspection machines, the product to be marked must first be positioned. The traditional positioning process is relatively complicated and it is not convenient to quickly remove or position the product, which increases the time required for product changeover and thus reduces the efficiency of the automatic marking and inspection machine. Utility Model Content

[0004] This utility model addresses the problem in existing technologies where the product to be marked is first positioned, but the traditional positioning process is complex and inconvenient for quickly removing or positioning the product, thus increasing the time required for product changeover and reducing the efficiency of automatic marking and inspection machines.

A ratchet is fixedly connected to the middle of the rotating shaft surface. A pawl is engaged with one end of the ratchet. A mounting base is rotatably connected to one end of the pawl.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example 1: This utility model provides an automatic marking and inspection machine, such as... Figures 1 to 5 As shown, it includes: a marking and detection body 1, a housing 2 fixedly connected to the bottom of the marking and detection body 1, a positioning frame 3 fixedly connected to the top edge of the housing 2, two positioning blocks 4 slidably connected to the top of the positioning frame 3, a rotating shaft 5 connected to the interior of each of the two positioning blocks 4, gears 6 fixedly connected to the two ends of the outer surface of the rotating shaft 5, a rack 7 meshing with the outer surface of the gears 6, the rack 7 fixedly connected to the interior of the positioning frame 3, a ratchet 8 fixedly connected to the middle of the surface of the rotating shaft 5, a pawl 9 engaged with one end of the ratchet 8, and a mounting base 10 rotatably connected to one end of the pawl 9, the mounting base 10 being fixedly... The marking and inspection body 1, which is fixedly connected to the inner wall of the positioning block 4, also includes a laser marking machine, an area array camera, a PLC control cabinet, and warning lights. During use, the laser marking machine is triggered by the PLC control cabinet to mark the required marks on the product surface according to the preset program. After marking is completed, the area array camera is controlled by the PLC control cabinet to photograph the marked area and detect the clarity, contrast, defects, and positional deviation of the product surface image. If the product fails the inspection, the warning lights are controlled by the PLC control cabinet to alert the staff. The above are all existing technologies in this field and will not be elaborated further here.

[0022] like Figure 2 , Figure 4 and Figure 5 As shown, a mounting base 11 is fixedly connected to the bottom end of the pawl 9. A baffle 12 is rotatably connected to the bottom end of the mounting base 11. A spring 13 is fixedly connected to the bottom end of the baffle 12. A positioning seat 14 is fixedly connected to the other end of the spring 13. The positioning seat 14 is fixedly connected to the inner wall of the positioning block 4. The spring 13 drives the baffle 12 and the mounting base 11 to squeeze the pawl 9, so that the rotation of the pawl 9 is restricted by the spring 13. The spring 13 squeezes the pawl 9, so that the pawl 9 returns to its original position. This avoids the problem of the ratchet 8 rotating unexpectedly because the pawl 9 cannot return to its original position, thus making the movement of the ratchet 8 controllable.

[0023] like Figure 2 , Figure 4 and Figure 5As shown, a protrusion 15 is fixedly connected to the top of the pawl 9. A connecting rod 16 is rotatably connected to one end of the protrusion 15. A driving block 17 is fixedly connected to the other end of the connecting rod 16. A spring 18 is fixedly connected to one end of the driving block 17. The other end of the spring 18 is fixedly connected to the outer surface of the positioning frame 3. First, the driving block 17 is pressed down. The driving block 17 drives the connecting rod 16 to move and squeezes the spring 18, causing the spring 18 to deform. The connecting rod 16 then pushes the protrusion 15 and the pawl 9 to rotate around the mounting base 10. At this time, the pawl 9 separates from the ratchet 8, so that the pawl 9 cannot engage with the ratchet 8, thereby allowing the ratchet 8 to rotate in the opposite direction, thus improving the flexibility of the ratchet 8.

[0024] like Figure 2 , Figure 4 and Figure 5 As shown, spring 18 is sleeved on the outside of connecting rod 16. When driving block 17 presses spring 18, spring 18 will deform. At this time, the connecting rod 16 inside spring 18 limits the deformation, thus avoiding the problem of excessive deformation angle of spring 18, and making the deformation angle of spring 18 more stable.

[0025] like Figures 2 to 5 As shown, the two ends of the gear 6 are in contact with the inner wall of the positioning block 4. During the rotation of the gear 6, the inner wall of the positioning block 4 restricts the rotation of the gear 6, making the rotation of the gear 6 more stable and thus avoiding the problem of offset when the gear 6 rotates, thereby improving the stability of the rotation process of the gear 6.

[0026] like Figures 1 to 3 As shown, two slide rods are provided at the top of the positioning frame 3. The positioning block 4 is slidably connected to the outer surface of the slide rod, and the rack 7 is embedded in the inside of the slide rod. By embedding the rack 7 inside the slide rod, the positioning block 4 is not affected when sliding on the outer surface of the slide rod, while the gear 6 can rotate stably on the surface of the rack 7. This ensures that the positioning block 4 is not affected by the internal structure of the slide rod, thereby improving the stability of the positioning block 4 when it moves.

[0027] Working principle: When using this device, the operator first places the product to be marked and inspected inside the positioning frame 3. Then, the operator pushes the two positioning blocks 4, causing them to move closer to the product. The movement of the positioning blocks 4 drives the rotating shaft 5 to move, which in turn drives the gear 6 and ratchet 8 to move synchronously. During the movement of the gear 6, it is restricted by the rack 7, causing the gear 6 to rotate. The gear 6 drives the rotating shaft 5 and ratchet 8 to rotate synchronously. As the ratchet 8 rotates, it continuously compresses the pawl 9, causing the pawl 9 to drive the mounting base 11 and the baffle 12 to rotate around the mounting base 10, and continuously compress the spring 13, causing the spring 13 to continuously deform and recover. When the two... When the positioning block 4 is aligned with the product, the movement stops. At this time, the spring 13 drives the pawl 9 to engage with the surface of the ratchet 8, preventing the ratchet 8 from rotating in the opposite direction. This completes the product positioning. Then, the operator controls the laser marking machine to engrave the required marks on the product surface according to the preset program through the PLC control cabinet. The printed product is then inspected by the area scan camera. If the inspected product is unqualified, the warning light is controlled by the PLC control cabinet to alert the operator. Qualified products proceed to the next step. By moving the two positioning blocks 4 to position the product, the product positioning process is improved, thereby reducing the complex steps required for product positioning and improving the marking and inspection efficiency of the device.

[0028] After a single product completes marking and inspection, the worker first pulls one of the drive blocks 17. Drive block 17 moves the connecting rod 16 and stretches the second spring 18, causing it to deform. The connecting rod 16 then pushes the protrusion 15 to rotate, which in turn causes the pawl 9 to rotate around the mounting base 10. At this point, the pawl 9 separates from the ratchet 8, preventing it from engaging. The worker then moves the positioning block 4 to separate it from the product and removes it. The worker then releases drive block 17 and reverses the above steps to position the next product. By pressing a single drive block 17, the ratchet 8 separates from the pawl 9, which in turn pushes the positioning block 4 to separate it from the product, allowing the product to be removed. This simplifies the product removal process and improves the efficiency of product replacement.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
