Description

Technical Field

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

[0002] Optical lenses are essential components in machine vision systems, which directly affect the quality of imaging and the implementation and effect 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, and some of the edges or frames of these 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.

[0004] After the lens barrel is processed by the injection molding process, there will be a mold line on its surface, which is generally polished manually using sandpaper or a polishing wheel. 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 at the step surface position, the dimensional error after polishing is large, which cannot meet the assembly requirements of the lens barrel.

[0043] In the embodiment of the present invention, when the second telescopic member 41 controls the X-axis moving frame 42 and the polishing disk 511 to move toward the lens plastic housing 7, 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, and the second telescopic member 41 continues to control the polishing disk 511 to move 5 cm or 10 cm, which is used to make the polishing disk 511 contact with the surface of the lens plastic housing 7;

[0044] 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 control the rotating sleeve 22 to rotate 90 degrees, so as to adjust the opening 222 of the rotating sleeve 22 to a vertical downward state.

[0045] Working principle: In the initial state, the opening 222 of the rotating sleeve 22 is facing vertically upward, and the lens plastic shell 7 stacked in the material guide shell 21 enters the rotating sleeve 22 through the opening 222;

[0046] 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 rotation of the rotating sleeve 22 by 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 chamber 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. 2 Continue to control the polishing disc 511 to move 5 cm or 10 cm, so as to make the end face of the polishing disc 511 contact with the surface of the lens plastic housing 7, and at the same time turn on the driving member 341 and the polishing motor 512. The driving member 341 controls the rotating tube 342, the round hole square tube 313, the suction cup 314 and the lens plastic housing 7 to rotate through the second transmission gear 343. When the polishing motor 512 controls the polishing disc 511 to polish the rotating surface of the lens plastic housing 7, the polishing disc 511 is controlled to move along the Y 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 in the shape of a cylinder with steps, the rotating frame 514 is controlled by the angle motor 513 to rotate 90 degrees with the motor shaft of the angle motor 513 as the axis, so that the side of the polishing disc 511 contacts with the step surface of the lens plastic housing 7, so as to achieve the purpose of polishing the parting line at the step surface position;

[0047] When the end parting line of the lens plastic housing 7 needs to be polished, firstly, one of the suction cups 314 is vacuumed by using the vacuum pump module 33 through the flexible tube 331, the plug connector 332 and the round hole square tube 313, and the other suction cup 314 is controlled to move in the direction away from the lens plastic housing 7 by using the first telescopic member 311, and then the rotating frame 514 is controlled to rotate 90 degrees with the motor shaft of the corner motor 513 as the axis by using the angle motor 513, and then the polishing assembly 51 is driven to move into the avoidance opening 223 by using the second telescopic member 41, and the polishing disc 511 is controlled to polish the end face of the lens plastic housing 7 by controlling the polishing assembly 51 to move along the Y guide rail 43, and the polishing principle of the other outer end face of the lens plastic housing 7 is consistent with the above principle;

[0048] After the polishing of the parting 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 vertical downward state. At this time, the lens plastic shell 7 enters the mesh feeding 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 feeding 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 in a vertical upward state again, and so on and so forth, thereby realizing the efficient polishing function of the parting line of the lens plastic shell 7.

[0049] To sum up, the present application utilizes the structural design of the material guiding mechanism 2, the clamping mechanism 3, the X-axis 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-axis guide rail 43, but also polish the cylindrical lens plastic shell 7 with steps and the mold lines at the two ends of the lens plastic shell 7. In the process of controlling the polishing mechanism 5 to polish, the first tooth groove 45 and the second tooth groove 46 can be connected with the first transmission gear 221 to achieve the purpose of automatic loading and unloading. It has the characteristics of ingenious structural coordination, applicable to the polishing of mold lines in different positions and high work efficiency.
