A support rod is fixedly connected to the top of the main frame, and a movable platform is slidably connected to the surface of the support rod. Diagonal rods are hinged to the front and rear sides of the top of the movable platform. Square slots that penetrate inside and out are opened on the left side of the front and back of the main frame. The outer ends of the diagonal rods extend to the outside of the square slots and are hinged to push-pull plates. Push-pull rods are fixedly connected to the left and right sides of the opposite side of the two push-pull plates. Follower plates are fixedly connected to the inner ends of the push-pull rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model achieves automatic trademark transfer by setting up a conveyor belt, coupled with an external motor drive to ensure stable operation, reduce manual intervention, and improve detection efficiency. The collaborative work of the in-warehouse visual inspection head, visual signal processing module, and labeling head constructs a complete "detection-analysis-labeling" closed-loop process. The visual inspection head captures trademark image information, and the visual signal processing module quickly analyzes and judges whether the trademark has defects. If defects are found, it promptly sends instructions to the labeling head for labeling, ensuring the accuracy and timeliness of detection. Furthermore, the pushing structure composed of the drive motor, cam, moving stage, inclined rod, push-pull plate, and other components can push the trademark placed on the conveyor belt towards the center, ensuring that the trademark is precisely positioned at the center of the conveyor belt when it reaches the detection point. This effectively avoids visual detection deviations caused by trademark positional offsets, significantly improving detection accuracy and labeling effect, and providing convenience for users.

[0014] 2. This utility model provides an upward elastic support force to the moving platform by setting an extended compression spring sleeved on the surface of the support rod. When the cam rotates and pushes the moving platform downward, the compression spring is compressed and stores elastic potential energy. When the cam disengages from the moving platform, the compression spring releases the elastic potential energy and pushes the moving platform to quickly return to its original position. This ensures that the moving platform can stably perform up-and-down reciprocating motion during operation. This elastic return mechanism not only makes the pushing structure run more smoothly and reduces wear and noise caused by rigid collisions, but also improves the service life of the equipment and ensures the continuity and stability of the pushing trademark action.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a trademark visual inspection device with labeling function, including a main frame 1. A conveyor belt 2 is installed inside the main frame 1, with both its front and back sides in contact with the inner wall of the main frame 1. The conveyor belt 2 is driven by an external motor. A processing chamber 3 is fixedly connected to the top right side of the main frame 1. A visual inspection head 4 is fixedly connected to the center of the top left side of the inner wall of the processing chamber 3. A liftable labeling head 5 is fixedly connected to the center of the top right side of the inner wall of the processing chamber 3. A visual signal processing module 6 is located between the visual inspection head 4 and the labeling head 5, positioned at the center of the top top of the inner wall of the processing chamber 3. The visual inspection head 4 is electrically connected to the labeling head 5 via the visual signal processing module 6. A support plate 7 is fixedly connected to the lower left side inside the main frame 1. A support rod 8 is fixedly connected to the top of the support plate 7. A moving platform 9 is slidably connected to the surface of the support rod 8. The front and rear sides of the top of the moving platform 9 are hinged with diagonal rods 10. The left side of the front and back of the main frame 1 is provided with a through square groove 11. The outer end of the diagonal rod 10 extends to the outside of the square groove 11 and is hinged with a push-pull plate 12. The left and right sides of the two push-pull plates 12 are fixedly connected with push-pull rods 13. The inner end of the push-pull rod 13 is fixedly connected with a follower plate 14. The bottom of the follower plate 14 is provided with a rubber push strip 15. The bottom of the rubber push strip 15 is in contact with the surface of the top of the conveyor belt 2. The drive motor 16 located on the right side of the moving platform 9 is fixedly connected to the inside of the main frame 1 through a support plate. The output end of the drive motor 16 is fixedly connected to a cam 17 through a coupling. The bottom of the cam 17 is in contact with the right side of the top of the moving platform 9. The left side of the front of the main frame 1 is fixedly connected with a control box. The control box is electrically connected to the vision inspection head 4, the labeling head 5 and the drive motor 16 respectively.

[0022] refer to Figure 2 A compression spring 18 is fitted on the surface of the support rod 8. The compression spring 18 is in an extended state. The top end of the compression spring 18 is fixedly connected to the bottom of the moving platform 9, and the bottom end of the compression spring 18 is fixedly connected to the top of the support plate 7.

[0023] As a technical optimization of this utility model, an extended compression spring 18 is provided on the surface of the support rod 8 to provide upward elastic support for the moving platform 9. When the cam 17 rotates and pushes the moving platform 9 downward, the compression spring 18 is compressed and stores elastic potential energy. When the cam 17 disengages from the moving platform 9, the compression spring 18 releases elastic potential energy and pushes the moving platform 9 to quickly reset, ensuring that the moving platform 9 can stably perform up-and-down reciprocating motion during operation. This elastic reset mechanism not only makes the pushing structure run more smoothly and reduces wear and noise caused by rigid collisions, but also improves the service life of the equipment and ensures the continuity and stability of the pushing trademark action.

[0024] refer to Figure 4 The outer surface of the cam 17 is provided with a slide groove 19, and a slide bar 20 that works in conjunction with the slide groove 19 is fixedly connected to the right side of the top of the moving platform 9. The surface of the slide bar 20 is slidably connected to the inner wall of the slide groove 19.

[0025] As a technical optimization of this utility model, the slide groove 19 on the outer surface of the cam 17 is used in conjunction with the top slide bar 20 of the moving table 9 to provide precise guidance for the movement of the moving table 9. The limiting effect of the slide groove 19 on the slide bar 20 ensures that the moving table 9 can only move in a straight line in the vertical direction under the drive of the cam 17, avoiding deviation or shaking. This allows the push-pull plate 12 and the rubber push bar 15 to accurately push the trademark towards the center of the conveyor belt 2, further improving the accuracy of trademark position adjustment, ensuring the accuracy of trademark position during visual inspection and labeling, and improving the quality of inspection and labeling.

[0026] refer to Figure 1 The surface of the push-pull rod 13 is fixedly connected to a sliding sleeve 21, and the surface of the sliding sleeve 21 is fixedly connected to the surface of the main frame 1.

[0027] As a technical optimization of this utility model, by setting a sliding sleeve 21 fixed to the surface of the push-pull rod 13 and fixedly connecting it to the main frame 1, a stable support and guide for the push-pull rod 13 is provided. The presence of the sliding sleeve 21 makes the push-pull rod 13 more stable when moving in the horizontal direction, reduces the position deviation caused by shaking, and ensures that the rubber push strip 15 can push the trademark along the predetermined trajectory. This enhances the stability and reliability of the pushing structure, avoids the impact of the shaking of the push-pull rod 13 on the trademark position adjustment effect, and helps to improve the overall quality of trademark inspection and labeling work.

[0028] refer to Figure 2 and Figure 3The top of the rubber pusher 15 is fixedly connected to a T-shaped strip 22, and the bottom of the follower plate 14 is provided with a T-shaped groove 23. The surface of the T-shaped strip 22 is in contact with the inner wall of the T-shaped groove 23. A magnetic sheet 24 is fixedly connected to the front of the T-shaped strip 22, and the back of the magnetic sheet 24 is magnetically connected to the front of the follower plate 14.

[0029] As a technical optimization of this utility model, by setting the T-shaped strip 22 at the top of the rubber pusher 15 and the T-shaped groove 23 at the bottom of the follower plate 14, a detachable connection between the rubber pusher 15 and the follower plate 14 is achieved, which facilitates the installation, disassembly and replacement of the rubber pusher 15. When the rubber pusher 15 is worn or damaged due to long-term use, it can be quickly removed from the follower plate 14 for replacement without disassembling the entire pushing structure, which greatly improves the ease of maintenance of the equipment. At the same time, the magnetic sheet 24 on the front of the T-shaped strip 22 is magnetically connected to the follower plate 14, which further simplifies the installation process while ensuring the stability of the connection, so that the rubber pusher 15 can be firmly fixed on the follower plate 14, ensuring the stability and reliability when pushing the trademark.

[0030] refer to Figure 4 Several evenly distributed support plates 25 are fixedly connected to the upper right side of the main frame 1. The top of the support plate 25 is provided with a smooth coating, and the top of the support plate 25 is in contact with the top of the inner wall of the conveyor belt 2.

[0031] As a technical optimization of this utility model, the bearing plate 25 fixed on the upper right side of the inner wall of the main frame 1 has a smooth coating on its top, which reduces the friction between the bearing plate 2 and the inner wall of the conveyor belt 2. During the operation of the conveyor belt 2, the bearing plate 25 can provide stable support for the conveyor belt 2, reduce the sagging and deformation of the conveyor belt 2 due to its own weight and the weight of the label, and ensure the smooth operation of the conveyor belt 2. At the same time, the smooth coating reduces the resistance of the conveyor belt 2, reduces the wear of the conveyor belt 2, extends the service life of the conveyor belt 2, and enables the label to pass smoothly through the visual inspection and labeling area on the conveyor belt 2, thereby improving the stability and reliability of the equipment operation.

[0032] The working principle and usage process of this utility model are as follows: During use, the trademark to be inspected is placed at the starting end of the conveyor belt 2. The power supply to the equipment is turned on, and the external motor is started to make the conveyor belt 2 begin to run. Simultaneously, the drive motor 16, vision inspection head 4, vision signal processing module 6, labeling head 5, and control box are turned on to ensure that all components are in normal working condition. The trademark moves forward with the conveyor belt 2. When it passes the pushing structure, the drive motor 16 drives the cam 17 to rotate, pushing the moving platform 9, inclined rod 10, push-pull plate 12, and other components to work together. When the cam 17 rotates and presses the moving platform 9 downwards, the compression spring 18 on the support rod 8 is compressed, storing elastic potential energy. After the cam 17 disengages from the moving platform 9, the compression spring 18 releases its elastic potential energy, pushing the moving platform 9 to quickly return to its original position, ensuring the continuity of the moving platform 9's movement. During the up-and-down movement of the moving platform 9, the two hinged inclined rods 10 drive the two push-pull plates 12 to slide horizontally inwards synchronously. The push-pull rod 13 on 12 drives the follower plate 14 and the rubber pusher 15 at the bottom to move synchronously, thereby realizing the synchronous pushing of the front and rear sides of the trademark on the conveyor belt 2, so that the trademark is accurately moved to the center position of the rubber pusher 15 on the conveyor belt 2, ensuring that the trademark is in the center position when it moves to the visual inspection area. When the trademark moves to the bottom of the visual inspection head 4, the visual inspection head 4 quickly collects the trademark image information and transmits the image data to the visual signal processing module 6 in real time. The visual signal processing module 6 analyzes and processes the image data and compares it with the preset standard trademark data to determine whether the trademark has defects. If the visual signal processing module 6 determines that the trademark has defects, it immediately sends an instruction to the labeling head 5. After receiving the instruction, the labeling head 5 descends and performs a labeling operation on the surface of the defective trademark to complete the marking of the defective trademark. If the trademark has no defects, the labeling head 5 remains in the original position, and the trademark continues to be conveyed forward with the conveyor belt 2 to enter the subsequent process.
