The first adjusting block presses down the push plate, and the push plate drives the mounting section and the slide rod to move downward and presses down the spring until the bottom surface of the mounting section is in contact with the top surface of the support plate, and the suction nozzle returns to its original position. The height of the suction nozzle can be automatically adjusted by the mutual movement between the two clamping jaws. 4. The three electric grippers move in a cycle through the suspension conveyor system, one gripping the lens, one placing the lens, and one cleaning the gripper after gripping the lens, which improves the efficiency of lens installation on the product.

[0041] The driving mechanism 9 includes a driving motor 91 and a rotating seat 92. The end of the top plate 81 close to the inner side of the suspension track 7 is bent upward by 90°. The driving motor 91 is installed on the bent side of the top plate 81. The rotating seat 92 is coaxially installed on the output shaft of the driving motor 91. The top and bottom of the rotating seat 92 are connected to a rotating disk 921; the inner side of the suspension track 7 is provided with a third annular groove 73 for the two rotating disks 921 to roll, and the inner wall of the third annular groove 73 is connected with a plurality of positioning columns 74, and the plurality of positioning columns 74 are evenly distributed along the third annular groove 73; the peripheral surface of the rotating disk 921 is provided with a plurality of arc-shaped card grooves 9211 used in conjunction with the positioning columns 74, and the arc-shaped card grooves 9211 are evenly distributed along the circumference of the rotating disk 921; the axes of the second roller 811, the first roller 821 and the rotating seat 92 are all in the same vertical plane.

[0042] When it is necessary to drive the suspension bracket 6 to move, the driving motor 91 drives the rotating seat 92 to rotate, and the rotating seat 92 drives the rotating disk 921 to rotate. The rotating disk 921 rolls in the third annular groove 73 through the positioning column 74, and the rotating disk 921 drives the suspension bracket 6 to move through the rotating seat 92 and the driving motor 91.

[0043] A positioning cylinder 812 is installed on the top surface of the top plate 81, and a positioning rod 813 is connected to the end of the piston rod of the positioning cylinder 812. Three positioning holes 75 for inserting the positioning rod 813 are provided on the top surface of the suspension track 7. The axis of the positioning hole 75 and the axis of the second roller 811 are both located in the same vertical plane. The three positioning holes 75 are all located at the three arc corners of the suspension track 7.

[0044] When the hanger 6 moves to a different station, the positioning cylinder 812 drives the positioning rod 813 to insert into the positioning hole 75 to position the hanger 6 so that the hanger 6 is in an accurate position and the deviation of the hanger 6 is reduced.

[0045] Three suspension brackets 6 are provided on the suspension track 7, each suspension bracket 6 is installed with a driving mechanism 9, and each suspension bracket 6 corresponds to a work station; the loading position 02 is used for the suction nozzle part 3 to grab the lens, the unloading position 03 is used to place the lens in the installation position of the shell, and the cleaning position 04 is used to clean the glue on the surface of the clamping claw part 2.

[0046] The three electric grippers 1 perform cyclic motions through a suspension conveying system, one for grabbing the lens, one for placing the lens, and one for cleaning the gripper 2 after gripping the lens, thereby improving the efficiency of lens installation on the product.

[0047] There is a working plate 01 under the hanging track 7, and a first cylinder 10 is installed on the top surface of the working plate 01, and the first cylinder 10 is set vertically; the first cylinder 10 is located at the cleaning position 04, and a second cylinder 101 is installed on the end of the piston rod of the first cylinder 10, and the second cylinder 101 is set horizontally; the end of the piston rod of the second cylinder 101 is connected to a mounting bar 102, and scrapers 103 are installed at both ends of the mounting bar 102, and the two scrapers 103 are respectively attached to the sides of the two clamping heads 24 that are close to each other.

[0048] After the clamping head 24 adjusts the lens position and solidifies it, the clamping head 24 moves to the cleaning position 04. If there is UV glue or other contaminants on one side of the lens clamped by the clamping head 24, when clamping the next lens, the contaminants will be between the lens and the clamping head 24, and the lens will be offset during clamping, affecting the adjustment of the lens; therefore, the first cylinder 10 drives the second cylinder 101 to rise, and the second cylinder 101 drives the scraper 103 to be inserted between the two clamping heads 24, and the first cylinder 10 drives the second cylinder 101 to descend, and the scraper 103 descends, and the scraper 103 scrapes the side of the clamping heads 24 that are close to each other to clean the contaminants on the surface, so as to facilitate the clamping of the subsequent lens.

[0049] The implementation principle of a gripper nozzle and its conveying system for lens transportation in an embodiment of the present application is as follows: when it is necessary to adsorb the lens, the electric gripper 1 drives the two gripper parts 2 to separate, and the adjustment mechanism 5 adjusts the suction nozzle part 3 to move downward so that the bottom end of the suction nozzle part 3 extends out of the bottom surface of the gripper part 2 or is flush with the gripper part 2; the moving mechanism 4 drives the electric gripper 1 to move, and moves the suction nozzle part 3 to adsorb the lens, moves the adsorbed lens to the installation position, and places the lens in the set position, and the suction nozzle part 3 releases the lens and removes the suction nozzle part 3. The electric gripper 1 drives the two gripper parts 2 to clamp the lens, and then irradiates the UV glue with ultraviolet light. During the irradiation process, the UV glue is cured. Since the lens is fixed by the gripper part 2, the deformation of the UV glue will not affect the lens, so that there will be no coupling deviation after fixation, which improves the product yield and solves the problem of reduced production efficiency.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
