[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 8 As shown, a gasket feeding mechanism for a camera lens comprises a lens holder 1, an adsorption mechanism 5 and a shifting mechanism 6. A support seat 2 is provided on one side of the lens holder 1, and a feeding mechanism 3 is provided directly above the support seat 2. The feeding mechanism 3 synchronously displaces and adjusts gaskets of different sizes, thereby facilitating the adsorption mechanism 5 to adsorb and feed the gaskets;

[0038] An adsorption shell 4 is provided on one side of the support seat 2, and an adsorption mechanism 5 is provided inside the adsorption shell 4. The adsorption mechanism 5 adjusts the adsorption height and placement position according to the height of the gasket, thereby facilitating the discharge of gaskets of different thicknesses;

[0039] A shifting mechanism 6 is provided on one side of the adsorption mechanism 5, and the shifting mechanism 6 adjusts the position of the adsorption mechanism 5, and then adjusts the adsorption angle of the adsorption mechanism 5 to improve the adsorption and feeding efficiency of gaskets of different thicknesses. A vertical sleeve shaft 7 is provided at the bottom end of the adsorption shell 4.

[0040] In this embodiment, the feeding mechanism 3 includes a material tray 31, a guide groove 32, a material placement groove 33, a displacement block 34, an electric lead screw 35 and a magnet column 36. The guide groove 32 is arranged on the outer side of the material support seat 2, and the displacement block 34 is arranged inside the guide groove 32. Magnet columns 36 are arranged at equal intervals on the top of the displacement block 34. The electric lead screw 35 is connected to the inside of the displacement block 34. The material placement grooves 33 are opened at equal intervals on the surface of the material tray 31. The displacement block 34 is arranged at the bottom end of the material tray 31, and the electric lead screw 35 is arranged inside the guide groove 32. The material tray 31 is adsorbed and connected to the outside of the magnet column 36.

[0041] In this embodiment, the displacement block 34 is connected to the bottom end of the material tray 31 through symmetrically arranged magnet columns 36. The displacement block 34 magnetically attracts the bottom end of the material tray 31 to prevent the material tray 31 from shaking during the displacement process.

[0042] In this embodiment, the material tray 31 is connected to the outer side of the electric lead screw 35 via a displacement block 34 provided at the bottom end. The material tray 31 is displaced by the electric lead screw 35 to adjust the material taking position, thereby improving the flexibility of the gasket replacement.

[0043] In this embodiment, the adsorption mechanism 5 includes an exhaust pump 51, an air intake pipe 52, a negative pressure suction cup 53, a cylinder 54 and a vacuum pump 55. The exhaust pump 51 is installed on the outside of the adsorption shell 4, and the output end of the exhaust pump 51 is connected to the exhaust end of the cylinder 54. The adsorption shell 4 is provided with a cylinder 54. The output end of the vacuum pump 55 is connected to the negative pressure suction cup 53, and the top of the negative pressure suction cup 53 is connected to the output end of the cylinder 54. The cylinder 54 and the vacuum pump 55 are installed inside the adsorption shell 4, and the air intake end of the cylinder 54 is connected to one end of the air intake pipe 52.

[0044] In this embodiment, the negative pressure suction cup 53 connected to the output end of the cylinder 54 is connected to the output end of the exhaust pump 51, and the negative pressure suction cup 53 is driven by the cylinder 54 to move up and down, thereby adjusting and controlling the installation height.

[0045] In this embodiment, the shifting mechanism 6 includes a transverse connecting arm 61, a base 62, a rolling bearing 63, an annular gear ring 64, a servo motor 65, a gear 66 and an electric shaft 67. The top of the base 62 is arranged at the bottom end of one side of the transverse connecting arm 61, and a rolling bearing 63 is arranged inside the transverse connecting arm 61. The outer side of the rolling bearing 63 is fitted with the outer side of the vertical sleeve shaft 7. The bottom end of the vertical sleeve shaft 7 is connected to the annular gear ring 64, and the outer side of the annular gear ring 64 is meshingly connected with a gear 66. The bottom end of the gear 66 is connected to the output end of the servo motor 65. The gear 66 is driven to rotate by the servo motor 65 to adjust the negative pressure suction cup 53 in a small range.

[0046] In this embodiment, a vertical sleeve shaft 7 is provided at the bottom end of the adsorption shell 4 and is connected to the outer side of the annular gear ring 64. The annular gear ring 64 drives the vertical sleeve shaft 7 to rotate and rotate its position in a small range.

[0047] In this embodiment, the base 62 is connected to the bottom end of the transverse connecting arm 61 through an electric shaft 67 disposed inside, and the electric shaft 67 drives the transverse connecting arm 61 to rotate, thereby performing a large range of rotation and transposition of the device.

[0048] The gasket feeding mechanism of the camera lens includes the following working processes in practical application:

[0049] Step 1: The operator first places gaskets of different diameters in the placing groove 33 provided on the outer side of the material tray 31 to position the gaskets. Since the diameter of the placing groove 33 is the size of the largest gasket, multiple groups of gaskets of different diameters can be fed and processed. The operator holds the material tray 31 so that the bottom end of the material tray 31 is aligned with the top end of the magnet column 36, and uses the magnet column 36 to adsorb the bottom end of the material tray 31, thereby completing the connection between the material tray 31 and the support seat 2;

[0050] Step 2: The operator then turns on the electric lead screw 35, and during the rotation of the electric lead screw 35, the displacement block 34 is driven to move inside the guide groove 32, and the displacement block 34 is used to drive the material tray 31 to move, so that the material tray 31 moves to the bottom of the negative pressure suction cup 53, and then turns off the electric lead screw 35. After the feeding of a group of gaskets is completed, the electric lead screw 35 is used to drive the material tray 31 to perform the transposition process again;

[0051] Step 3: Before use, the operator can turn on the servo motor 65, use the servo motor 65 to drive the gear 66 to rotate, use the gear 66 to mesh with the outer side of the annular gear ring 64, use the annular gear ring 64 to drive the vertical sleeve shaft 7 and the adsorption shell 4 to rotate, adjust the angle of the adsorption shell 4, and rotate the vertical sleeve shaft 7 on the outer side of the rolling bearing 63. By tilting the adsorption shell 4, the surface of the gasket is vertically contacted to ensure the side position of the gasket is adsorbed, and then turn off the servo motor 65;

[0052] Step 4: When the rodless chamber set inside the cylinder 54 inputs compressed air through the air inlet pipe 52 and the rod chamber is exhausted, the pressure difference between the two chambers of the cylinder will generate a force acting on the piston, pushing the piston to move, so that the piston rod is extended, and the piston rod is used to drive the negative pressure suction cup 53 to move vertically downward, and the vacuum pump 55 set in the process of the negative pressure suction cup 53 is used to continuously form a vacuum or negative pressure (relative vacuum) on the negative pressure suction cup 53, and form a slight positive pressure at the exhaust nozzle, and the negative pressure suction cup 53 is used to adsorb the lens gasket;

[0053] Step 5: Then, the exhaust pump 51 is turned on again to directly exhaust the compressed air in the rodless chamber set in the cylinder 54. When the rodless chamber is exhausted, the piston rod will retract, so that the gasket moves vertically upward, so that the gasket and the inside of the material placement groove 33 are moved out, and then the electric shaft 67 drives the horizontal connecting arm 61 and the adsorption shell 4 to move, and then the position of the gasket is replaced, so that the gasket moves to the upper end of the lens;

[0054] Step 6: Once again, the rodless chamber set inside the cylinder 54 inputs compressed air through the air inlet pipe 52 to push the piston to move, so that the piston rod extends, so that the gasket is set inside the lens, and then the vacuum pump 55 is turned off, so that the negative pressure suction cup 53 can continue to form a vacuum environment and disappear, thereby separating the gasket from the negative pressure suction cup 53, and completing the assembly of the gasket and the lens.

[0055] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
