[0021] Now, in combination with the attached drawings and preferred embodiments, the present utility model will be further described in detail. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0022] Refer to Figure 1 , Figure 2 and Figure 3 As shown, the present utility model provides a technical solution: a positioning device for a glue dispenser, including a glue dispenser body 1. A hollow box 2 is fixedly connected to the top of the glue dispenser body 1. A baffle 3 is fixedly connected to the inside of the hollow box 2. Notches 4 are opened at the top of the baffle 3 and the top of the hollow box 2. An intersection hole 5 is opened at one end of the hollow box 2. A driving rod 6 is rotatably connected to the inside of the intersection hole 5. The other end of the driving rod 6 is fixedly connected to a gear 7. Racks 8 are meshedly connected to the top and bottom of the gear 7. A fixed block 9 is fixedly connected to one side of the rack 8. A positioning plate 10 is fixedly connected to the other side of the fixed block 9. The staff places the workpiece to be processed on the positioning plate 10, then starts the control system of the glue dispenser body 1, and then rotates the driving rod 6. The rotation of the driving rod 6 drives the gear 7 to rotate synchronously. Due to the meshing relationship between the gear 7 and the rack 8, the rotation of the gear 7 will be further converted into the linear motion of the rack 8. By using the principle of transmission, the rotational motion is converted into linear motion, realizing the precise adjustment of the position of the positioning plate 10, so that the workpiece can be accurately positioned within the working area of the glue dispenser body 1.

[0023] Refer to Figure 4 As shown in this embodiment: Extension plates 11 are fixedly connected to both ends of the rack 8. Limit holes 12 are opened on one side of the extension plates 11. A plurality of limit rods 13 are fixedly connected to the inside of the hollow box 2. The surface of the limit rod 13 is slidably connected to the inside of the limit hole 12. By opening the limit hole 12 on one side of the extension plate 11 and the cooperation of the limit hole 12 and the limit rod 13, the stability and precision of the rack 8 during the linear motion are ensured. The limit rod 13 serves as a guiding member, effectively preventing the rack 8 from shifting or shaking during the movement.

[0024] Refer to Figure 4As shown, in this implementation: One side of the extension plate 11 is fixedly connected to a return spring 14, and one side of the return spring 14 is fixedly connected to the inside of the hollow box 2. When the extension plate 11 moves or adjusts under the action of an external force, the return spring 14 can respond flexibly, absorb and store the energy generated by the movement. Once the external force disappears, the return spring 14 will quickly release the stored energy, pushing the extension plate 11 to automatically reset to the initial position, ensuring the stability of the structure and the convenience of use.

[0025] Referring to Figure 3 and Figure 5 As shown, in this implementation: One end of the hollow box 2 is fixedly connected to a circular hollow block 15. A plurality of tapered grooves 20 are formed inside the circular hollow block 15. One end of the driving rod 6 is provided with a moving groove 16. A moving block 17 is slidably connected to the inside of the moving groove 16. One end of the moving block 17 is fixedly connected to a handle 18. A plurality of tapered blocks 19 are fixedly connected to the surface of the handle 18. When the positioning plate 10 is in the state of positioning the workpiece, in order to further lock the position of the driving rod 6 and prevent it from rotating accidentally during the working process, by holding the handle 18 and pushing the handle 18 towards the circular hollow block 15, the tapered blocks 19 fixedly connected to the surface of the handle 18 are aligned with and slide into the tapered grooves 20 inside the circular hollow block 15, forming a stable locking mechanism.

[0026] Referring to Figure 5 As shown, in this implementation: The other end of the moving block 17 is fixedly connected to a tension spring 21, and the other end of the tension spring 21 is fixedly connected to the inside of the moving groove 16. When the handle 18 is pulled outwards, the tension spring 21 will start to store energy. When the pulling force on the handle 18 is released, the tension spring 21 will quickly release the stored elastic force and automatically pull the moving block 17 and the handle 18 back to the initial position.

[0027] Referring to Figure 5 As shown, in this implementation: Limiting grooves 22 are formed on both sides of the inner cavity of the moving groove 16, and limiting blocks 23 are fixedly connected to both sides of the moving block 17. When the handle 18 is pulled outwards and drives the driving rod 6 to rotate, the limiting blocks 23 will abut against the limiting grooves 22, effectively preventing the moving block 17 from being pulled out too much from the inside of the moving groove 16 and falling off.

[0028] Referring to Figure 5 As shown, in this implementation: The surface of the tapered block 19 is slidably connected to the inside of the tapered groove 20, and the external shape of the tapered block 19 matches the internal shape of the tapered groove 20. Due to the precise matching of the external shape of the tapered block 19 and the internal shape of the tapered groove 20, this tight sliding connection not only reduces the gap between the two, but also greatly enhances the stability of the overall structure.

[0029] Working principle: The staff places the workpiece to be processed on the positioning plate 10, then starts the control system of the dispensing machine body 1, and then rotates the driving rod 6. The rotation of the driving rod 6 drives the gear 7 to rotate synchronously. Due to the meshing relationship between the gear 7 and the toothed plate 8, the rotation of the gear 7 will be further converted into the linear motion of the toothed plate 8. By utilizing the principle of transmission, the rotational motion is converted into linear motion, achieving precise adjustment of the position of the positioning plate 10, so that the workpiece can be accurately positioned within the working area of the dispensing machine body 1. By providing a limit hole 12 on one side of the extension plate 11 and using the cooperation of the limit hole 12 and the limit rod 13, the stability and accuracy of the toothed plate 8 during linear motion are ensured. The limit rod 13, as a guiding component, effectively prevents the toothed plate 8 from shifting or shaking during movement. When the extension plate 11 moves or adjusts under an external force, the return spring 14 can respond flexibly, absorb and store the energy generated by the movement. Once the external force disappears, the return spring 14 will quickly release the stored energy and push the extension plate 11 to automatically reset to the initial position, ensuring the stability of the structure and the convenience of use. When the positioning plate 10 is in the state of positioning the workpiece, in order to further lock the position of the driving rod 6 and prevent it from rotating accidentally during operation, hold the handle 18 and push the handle 18 towards the direction of the circular hollow block 15, so that the conical block 19 fixedly connected to the surface of the handle 18 aligns with and slides into the conical groove 20 inside the circular hollow block 15, forming a stable locking mechanism. When the handle 18 is pulled outwards, the tension spring 21 will start to store energy. When the pulling force on the handle 18 is released, the tension spring 21 will quickly release the elastic force it stores and automatically pull the moving block 17 and the handle 18 back to the initial position. When the handle 18 is pulled outwards and drives the driving rod 6 to rotate, the limit block 23 will abut against the limit groove 22, which can effectively prevent the moving block 17 from being pulled out too much from the inside of the moving groove 16 and falling off. Due to the precise matching of the external shape of the conical block 19 and the internal shape of the conical groove 20, this tight sliding connection not only reduces the gap between the two but also greatly enhances the stability of the overall structure.
