[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Understandably, referring to Figures 1 to 4 The suction nozzle mechanism of the first aspect of this utility model includes a main body 100 and a suction nozzle assembly 200. The main body 100 is provided with an air intake channel 110, and the air intake channel 110 is provided with a plurality of suction holes 111, which are arranged at intervals. The suction nozzle assembly 200 includes a rectangular suction nozzle 210 and a circular suction nozzle 220. Both the rectangular suction nozzle 210 and the circular suction nozzle 220 are connected to the suction holes 111, and the rectangular suction nozzle 210 and the suction hole 111, as well as the circular suction nozzle 220 and the suction hole 111, are in one-to-one correspondence.

[0034] The main body 100 is provided with an air intake channel 110, which has multiple suction holes 111. These suction holes 111 are arranged at intervals. Rectangular suction nozzles 210 and circular suction nozzles 220 are both connected to the suction holes 111, with each rectangular suction nozzle 210 corresponding to one of the suction holes, and each circular suction nozzle 220 corresponding to one of the suction holes 111. This allows airflow to enter the air intake channel 110 from either the rectangular or circular suction nozzles 210, facilitating the effective adhesion of the rectangular and circular suction nozzles 210 to the lens cable and improving the stability of the lens adhesion. By accommodating the lens cable with a rectangular suction nozzle 210, the contact area with the lens cable is increased, enhancing the suction force on the lens, reducing the risk of the lens falling, and improving the stability of the adhesion.

[0035] It should be noted that the rectangular nozzle 210 can be understood as the projected shape of the nozzle being rectangular, and the circular nozzle 220 can be understood as the projected area of ​​the nozzle being circular.

[0036] Understandably, referring to Figure 1 , Figure 2 and Figure 4The rectangular suction nozzle 210 is provided with a first elastic suction cup 211, which has an elongated hole 212 that communicates with the suction hole 111. The rectangular suction nozzle 210, with its first elastic suction cup 211 and elongated hole 212, allows airflow to enter the suction hole 111 through the elongated hole 212, thereby adsorbing the lens cable. The elongated hole 212 increases the airflow area, thus increasing the adsorption force and fully covering and adapting to the width range of the lens cable. Simultaneously, it ensures that airflow smoothly enters the suction channel 110 through the elongated hole 212, improving the uniformity of airflow distribution and enhancing the overall adsorption force of the suction nozzle assembly 200 on the cable.

[0037] It should be noted that the first elastic suction cup 211 can be made of silicone or rubber, so that the first elastic suction cup 211 can deform when it comes into contact with the lens cable, so that the first elastic suction cup 211 can smoothly fit the lens cable, thereby improving the stability and safety of lens handling.

[0038] Specifically, the first elastic suction cup 211 is detachably connected to the rectangular suction nozzle 210 so that the first elastic suction cup 211 can be easily disassembled and assembled, facilitating the maintenance of the rectangular suction nozzle 210 and extending its service life.

[0039] The first elastic suction cup 211 can be connected to the rectangular suction nozzle 210 by means of adhesive, snap-fit, fastener connection, etc., which is not limited here.

[0040] Specifically, refer to Figure 1 , Figure 2 and Figure 4 The walls at both ends of the cross-section of the elongated hole 212 are both designed as arc-shaped surfaces 213. By designing the walls at both ends of the cross-section of the elongated hole 212 as arc-shaped surfaces 213, it helps to reduce stress concentration caused by changes in the shape of the lens cable or the action of lateral forces during adsorption. This allows the first elastic suction cup 211 to deform uniformly when it abuts against the lens cable, reducing the possibility of wrinkles forming due to deformation and minimizing the risk of vacuum breakage. This results in a more reliable sealed space. When the suction nozzle assembly 200 generates negative pressure through the suction channel 110, the arc-shaped surface 213 design can more effectively guide the airflow into the elongated hole 212 and distribute it evenly along the surface of the lens cable, thereby enhancing the overall adsorption effect, enabling stable lens transport, and improving the reliability of adsorption.

[0041] Specifically, refer to Figure 1 , Figure 2 and Figure 4The lower end face of the first elastic suction cup 211 is set as a plane 214. By setting the lower end face of the first elastic suction cup 211 as a plane 214, it helps to ensure that the first elastic suction cup 211 can be stably attached to the lens cable during the adsorption process, forming a uniform sealed space and reducing the possibility of air leakage from the first elastic suction cup 211.

[0042] In addition, the plane 214 can effectively guide the airflow into the elongated hole 212 and distribute it evenly along the surface of the leather wire. This not only improves the adsorption effect, but also makes the nozzle assembly 200 more stable during transportation, reducing the risk of lens shaking or falling due to uneven airflow distribution, and improving adsorption efficiency and stability.

[0043] Understandably, referring to Figure 1 , Figure 2 and Figure 4 The circular suction nozzle 220 is equipped with a second elastic suction cup 221. The second elastic suction cup 221 is conical in shape, and its diameter gradually increases in the direction away from the circular suction nozzle 220. By setting the second elastic suction cup 221 to a conical shape, when the second elastic suction cup 221 abuts against the lens cable, its edge first abuts against the lens cable, and then deforms to fit snugly against the lens cable. This allows for the covering of a larger area, helping to form a tighter seal, thereby improving suction efficiency and stability.

[0044] In addition, the conical second elastic suction cup 221 can better guide the airflow during the adsorption process, so that the airflow can be evenly distributed along the leather line, which not only improves the adsorption effect, but also reduces the possibility of the lens falling off due to uneven airflow distribution.

[0045] Understandably, referring to Figure 1 The number of rectangular suction nozzles 210 and circular suction nozzles 220 is set to multiple. By setting the number of rectangular suction nozzles 210 and circular suction nozzles 220 to multiple, the flexibility and versatility of the suction nozzle mechanism can be improved, which is conducive to enhancing the adsorption force on the lens cable, reducing the possibility of the lens falling, and improving the reliability of lens handling.

[0046] Understandably, referring to Figure 5 and Figure 6The handling device of the second aspect of the present invention includes a moving component (not shown in the drawings), a connecting pipe 310, and a suction nozzle mechanism of the first aspect of the present invention. The connecting pipe 310 is connected to the movable end of the moving component, and the moving component is used to drive the connecting pipe 310 to move. The main body 100 is provided with a vent pipe 120, which is connected to the suction channel 110. The vent pipe 120 is inserted into the connecting pipe 310 and is connected to the connecting pipe 310.

[0047] The connecting tube 310 is connected to the movable end of the moving component. The moving component can drive the connecting tube 310 to move. The main body 100 is provided with a vent tube 120. By inserting the vent tube 120 into the connecting tube 310, the connecting tube 310 can be connected to the vent tube 120. This facilitates the installation of the suction nozzle mechanism and allows airflow to enter the suction channel 110 and the connecting tube 310 sequentially from the rectangular suction nozzle 210 or the circular suction nozzle 220. This allows the main body 100 to be smoothly driven by the moving component, which facilitates the suction of the lens cable through the suction nozzle mechanism, making it easier to transport the lens and improving transport efficiency and reliability.

[0048] It should be noted that the moving component can be a robotic arm, linear cylinder, electric actuator, linear slide module, etc., as long as it can drive the connecting tube 310 to move to move the lens. The connecting tube 310 is connected to an air source such as an air pump, which can drive airflow to be drawn in from the suction nozzle mechanism. There are no restrictions on this.

[0049] Understandably, referring to Figure 5 and Figure 6 The side wall of the connecting pipe 310 is provided with an opening groove 320, and the side wall of the vent pipe 120 is provided with a connecting shaft 121 protruding from it. The connecting shaft 121 is slidably connected to the opening groove 320. An elastic element 330 is provided between the connecting pipe 310 and the main body 100. The elastic element 330 is used to drive the connecting shaft 121 to abut against the bottom wall of the opening groove 320. The side wall of the connecting pipe 310 is provided with an opening groove 320, and the side wall of the vent pipe 120 is provided with a connecting shaft 121 protruding out. By inserting the vent pipe 120 into the connecting pipe 310 and placing the connecting shaft 121 in the opening groove 320, the vent pipe 120 can be easily positioned in the circumferential direction of the connecting shaft 121. One end of the elastic member 330 abuts against the connecting pipe 310, and the other end abuts against the main body 100, so that the elastic member 330 can drive the connecting shaft 121 to abut against the bottom wall of the opening groove 320, thereby enabling the main body 100 to be stably connected to the connecting pipe 310.

[0050] In addition, by providing an elastic element 330 between the connecting tube 310 and the main body 100, when the moving component drives the rectangular suction nozzle 210 or the circular suction nozzle 220 to abut against the lens cable, the main body 100 can compress the elastic element 330 and cause the vent tube 120 to retract into the connecting tube 310, thereby buffering the impact of the rectangular suction nozzle 210 or the circular suction nozzle 220 on the lens cable and avoiding damage to the lens cable.

[0051] It should be noted that the elastic element 330 can be a spring, or an elastic silicone pad, rubber pad, etc., and is not limited here.

[0052] Specifically, refer to Figure 5 and Figure 6 The opening groove 320 includes a first groove 321, a second groove 322, and a third groove 323. The first groove 321 and the third groove 323 are arranged axially along the connecting pipe 310, and the first groove 321 extends to the end face of the connecting pipe 310. The second groove 322 is arranged circumferentially along the connecting pipe 310. The second groove 322 is connected to the first groove 321 and the third groove 323 respectively. The connecting shaft 121 can slide in the first groove 321, the second groove 322, or the third groove 323. The first groove 321 and the third groove 323 are both arranged along the axial direction of the connecting pipe 310, and the second groove 322 is arranged along the circumference of the connecting pipe 310. The first groove 321 extends to the end face of the connecting pipe 310 so that when the vent pipe 120 is inserted into the connecting pipe 310, the connecting shaft 121 can extend from the first groove 321. Then, the vent pipe 120 is rotated so that the connecting shaft 121 slides from the first groove 321 into the second groove 322. Then, the connecting shaft 121 slides from the second groove 322 into the bottom wall of the third groove 323, so that the vent pipe 120 can be stably placed on the connecting pipe 310, thereby improving the reliability of the connection.

[0053] It should be noted that when the connecting shaft 121 slides into the first groove 321, the main body 100 compresses the elastic element 330, and then drives the vent pipe 120 to rotate, causing the connecting shaft 121 to slide from the second groove 322 into the third groove 323. The elastic element 330 drives the vent pipe 120 to move away from the connecting pipe 310, and causes the connecting shaft 121 to abut against the bottom wall of the third groove 323, thereby reducing the possibility of the vent pipe 120 coming off the connecting pipe 310 and improving the stability of the connection.

[0054] Understandably, referring to Figure 5 and Figure 6The number of connecting pipes 310 and suction nozzle mechanisms is set to multiple, with a one-to-one correspondence between the connecting pipes 310 and the suction nozzle mechanisms. By setting multiple connecting pipes 310 and multiple suction nozzle mechanisms, the moving component can drive multiple connecting pipes 310 and multiple suction nozzle mechanisms to move synchronously, thereby improving the efficiency of the handling equipment in handling lenses. This significantly enhances the parallel processing capability of the handling equipment, reduces waiting time and operational complexity, and thus improves the automation level and production efficiency of the entire production line.

[0055] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
