Description

Technical Field

[0001] The present invention relates to the technical field of polishing, and in particular to a device for polishing the mold line of an optical lens plastic part. Background Art

[0002] Optical lenses are essential components in machine vision systems, directly affecting the quality of imaging and the implementation and effectiveness of algorithms. Optical lenses can be divided into short-focus lenses, medium-focus lenses, and long-focus lenses based on focal length; wide-angle, standard, and telephoto lenses based on field of view; and fixed-aperture fixed-focus lenses, manual-aperture fixed-focus lenses, automatic-aperture fixed-focus lenses, manual-zoom lenses, automatic-zoom lenses, automatic-aperture electric-zoom lenses, and electric three-variable lenses based on structure.

[0003] The plastic parts of optical lenses refer to the plastic parts used in lens assemblies. Lenses are usually composed of multiple optical elements, including lenses, prisms and other optical components. The edges or frames of some optical elements can be made of plastic materials. Plastic materials can provide lightweight and strength advantages. The lens barrel in the camera is also usually made of plastic materials. The lens barrel can not only adjust the magnification by adjusting the distance, but also play a role in dustproof, waterproof and protective.

Manual polishing has the following defects: (1) The work efficiency is low and cannot meet the needs of large-scale production; (2) When there are features such as steps on the surface of the lens barrel, since it is impossible to manually control the sandpaper or grinding wheel to polish the mold line of the step surface, the dimensional error after polishing is large, and thus it cannot meet the assembly requirements of the lens barrel.

[0037] In this embodiment of the present invention, when the second telescopic member 41 controls the X-axis movable frame 42 and the polishing plate 511 to move toward the lens plastic housing 7, the movable transmission rod 44 is connected to the first transmission gear 221 via the first tooth groove 45 to achieve the purpose of controlling the rotating sleeve 22 to rotate 90 degrees, thereby adjusting the opening 222 of the rotating sleeve 22 to a horizontal state. The second telescopic member 41 continues to control the polishing plate 511 to move 5 cm or 10 cm, thereby bringing the polishing plate 511 into contact with the surface of the lens plastic housing 7. When the second telescopic member 41 controls the polishing disc 511 to enter the avoidance opening 223, the moving transmission rod 44 is connected to the first transmission gear 221 through the second tooth groove 46 to achieve the purpose of controlling the rotating sleeve 22 to rotate 90 degrees, which is used to adjust the direction of the opening 222 of the rotating sleeve 22 to a vertical downward state.

[0038] Working principle: In the initial state, the opening 222 of the rotating sleeve 22 is facing vertically upward, and the lens plastic housing 7 stacked in the material guide housing 21 enters the rotating sleeve 22 through the opening 222; First, the first telescopic member 311 controls the movement of the suction cup 314 through the linkage plate 312, the plug connector 332 and the round hole square tube 313, so that the lens plastic shell 7 is fixedly clamped between the two suction cups 314, and then the second telescopic member 41 drives the X-axis moving frame 42 and the polishing mechanism 5 to move toward the lens plastic shell 7 along the X direction. In this process, the moving transmission rod 44 is connected to the first transmission gear 221 through the first tooth groove 45 to achieve the purpose of controlling the rotating sleeve 22 to rotate 90 degrees, which is used to adjust the opening 222 of the rotating sleeve 22 to a horizontal state. At this time, the polishing disc 511 moves to the position of the open accommodating cavity 211. When the lens plastic shell 7 is in the shape of a cylinder, the motor shaft of the polishing motor 512 is perpendicular to the surface of the lens plastic shell 7 or the motor shaft of the polishing motor 512 is perpendicular to the axis of the lens plastic shell 7. The second telescopic member 41 is connected to the X-axis moving frame 4 The polishing disc 511 is continuously controlled to move 5 cm or 10 cm to bring the end face of the polishing disc 511 into contact with the surface of the lens plastic housing 7. Simultaneously, the driving member 341 and the polishing motor 512 are turned on. The driving member 341 controls the rotation tube 342, the round-hole square tube 313, the suction cup 314, and the lens plastic housing 7 to rotate via the second transmission gear 343. The polishing motor 512 controls the polishing disc 511 to polish the rotating surface of the lens plastic housing 7 while controlling the polishing disc 511 to move along the Y-direction guide rail 43 on the surface of the X-direction moving frame 42 while polishing the parting line. When the lens plastic housing 7 is shaped like a cylinder with a step, the angular motor 513 is used to control the rotatable frame 514 to rotate 90 degrees about the motor shaft of the angular motor 513, so that the side face of the polishing disc 511 contacts the step surface of the lens plastic housing 7, thereby achieving the purpose of polishing the parting line at the step surface position. When the end of the lens plastic housing 7 needs to be polished at the mold line, the vacuum pump module 33 is first used to evacuate one of the suction cups 314 through the flexible tube 331, the plug connector 332 and the round-hole square tube 313. The first telescopic member 311 is used to control the other suction cup 314 to move away from the lens plastic housing 7. Then, the angular motor 513 is used to control the rotating frame 514 to rotate 90 degrees about the motor shaft of the angular motor 513. Then, the second telescopic member 41 is used to drive the polishing assembly 51 to move into the avoidance opening 223. The polishing assembly 51 is controlled to move along the Y-guide rail 43 to control the polishing disc 511 to polish the end face of the lens plastic housing 7. The polishing principle of the other outer end face of the lens plastic housing 7 is the same as the above principle. After the polishing of the mold line is completed, the first clamping assembly 31 and the second clamping assembly 32 first cancel the fixation of the lens plastic shell 7, and then the second telescopic member 41 is used to continue to control the X-direction moving frame 42 and the polishing mechanism 5 to move along the X-direction. The polishing assembly 51 passes through the avoidance opening 223, and the moving transmission rod 44 is connected to the first transmission gear 221 through the second tooth groove 46 to achieve the purpose of controlling the rotating sleeve 22 to rotate 90 degrees, which is used to adjust the opening 222 of the rotating sleeve 22 to a vertically downward state. At this time, the lens plastic shell 7 enters the mesh-type discharge channel 212 through the opening 222 under the action of gravity. During the polishing process, the polishing agent sprayed by the polishing agent spraying mechanism 6 is discharged from the mesh on the lower surface of the mesh-type discharge channel 212. Finally, the second telescopic member 41 continues to control the X-direction moving frame 42 and the polishing mechanism 5 to reset, so that the opening 222 of the rotating sleeve 22 is back in a vertically upward state. This reciprocating process achieves an efficient polishing function for the mold line of the lens plastic shell 7.

[0039] To sum up, the present application utilizes the structural design of the material guiding mechanism 2, the clamping mechanism 3, the X-direction moving mechanism 4 and the polishing mechanism 5 that cooperate with each other, which can not only polish the mold line on the surface of the cylindrical lens plastic shell 7 along the Y-direction guide rail 43, but also can polish the cylindrical lens plastic shell 7 with steps and the mold lines at both ends of the lens plastic shell 7. In the polishing process of controlling the polishing mechanism 5, the first tooth groove 45 and the second tooth groove 46 can also be used to connect with the first transmission gear 221 to achieve the purpose of automatic loading and unloading. It has the characteristics of clever structural coordination, applicability to polishing of mold lines in different positions and high work efficiency.
