Description

Technical Field

[0021] The convex outer walls of the plurality of optical lenses are attached to the inner wall of the polishing pad;

[0026] The concave and convex surfaces of several groups of optical lenses are polished and ground simultaneously;

[0027] After polishing is completed, the spin limit mechanism is controlled to transfer several groups of optical lenses to the unloading conveyor belt;

[0028] Repeat the above steps until the polishing work is completed.

[0029] The beneficial effects of the present invention are:

[0030] 1. By controlling the self-spinning limit mechanism, the convex outer walls of several groups of optical lenses are driven to fit onto the inner wall of the polishing pad. Subsequently, several groups of concave grinding mechanisms are controlled to extend into the concave surfaces of several groups of optical lenses. Then, the self-spinning limit mechanism is controlled to drive several groups of optical lenses to rotate. In conjunction with the rotation of the rotating disk, after the polishing liquid is injected into the polishing pad, the convex and concave surfaces of several groups of optical lenses can be polished synchronously. Moreover, the polishing liquid moves relative to the optical lens under the rotation of the rotating disk, thereby taking away the heat generated during the grinding process of the optical lens. This improves the processing effect of the optical lens while avoiding damage to the optical lens caused by high temperature.

[0031] 2. By controlling the lens clamps on several groups of positioning plates to clamp toward the corresponding optical lenses, the corresponding clamping gaskets are made to contact the edge protrusions of the optical lenses. Then, several groups of positioning plates are controlled to adjust the angles in the horizontal direction, so that several groups of optical lenses can enter the convex surface grinding mechanism according to the corresponding angles. When performing the synchronous grinding of the concave and convex surfaces of the optical lenses, several groups of guide plates can be controlled to drive the optical lenses to rotate in the opposite direction of the concave surface grinding through the clamping gaskets, so as to avoid deformation of the optical lenses due to unidirectional stress and uneven temperature.

[0032] 3. By controlling the descent of several groups of grinding motors and driving the fixing plates to descend at the same time, several groups of mounting rings can enter the grinding groove through the arc surface of the outer wall edge and fit on the inner wall of the polishing pad. During the grinding process of the optical lens, since several groups of optical lenses are polished synchronously and the polishing liquid flows relative to the optical lens, the magnetic filter screens and several groups of filter membranes arranged in the several groups of mounting rings can grade and filter the metal and glass debris in the polishing liquid, avoiding affecting the polishing work of the optical lens behind the flow direction of the polishing liquid, thereby improving the quality of the polishing work of the optical lens.

[0033] 4. Place the optical lenses to be polished on the loading conveyor belt in turn, then control the robotic arm to drive the spin limit mechanism to clamp several groups of optical lenses, and transfer several groups of optical lenses to the convex surface polishing mechanism, then control several groups of installation and polishing mechanisms to enter the concave surface of the optical lens, so that the concave and convex surfaces of the optical lens can be polished synchronously. After the polishing and polishing work is completed, control the robotic arm and the spin limit mechanism to transfer several groups of optical lenses to the unloading conveyor belt, and the loading conveyor belt runs intermittently, while the unloading conveyor belt runs continuously, so that the polishing and polishing work of the optical lens always remains continuous.

[0049] For example, Figure 4 and Figure 5 As shown, the spin limit mechanism 8 includes several groups of positioning plates 801; one group of the positioning plates 801 is transmission-connected to the output end of the robot arm 7; the remaining groups of the positioning plates 801 are symmetrically transmission-connected to the two side walls of the above-mentioned positioning plates 801 in sequence; a group of slide grooves 802 are opened on the side wall away from the robot arm 7; two groups of motor boxes 803 are symmetrically arranged in each group of the slide grooves 802; the bottom of each group of the motor boxes 803 is transmission-connected to a group of lens clamping plates 804; a group of guide plates 805 are movably passed through each group of the lens clamping plates 804; the top cross-section of each group of the guide plates 805 is semicircular; a group of clamping gaskets 806 are provided on the inner wall of each group of the guide plates 805 ; A group of guide racks 807 are provided on the outer wall of each group of guide plates 805; the output end of each group of motor boxes 803 extends to the corresponding group of lens clamps 804, and is transmission-connected with a group of guide gears 808; each group of guide gears 808 is meshed with the corresponding group of guide racks 807; each group of slide grooves 802 is provided with two groups of screw rods 809; one end of the corresponding two groups of screw rods 809 is fixedly connected, and the other end is rotationally connected to the corresponding side inner wall of the slide groove 802; two groups of sliders 810 are slidingly connected in each group of slide grooves 802; each group of sliders 810 is threadedly connected to the corresponding group of screw rods 809; each group of sliders 810 is transmission-connected with the corresponding group of motor boxes 803.

[0050] When polishing and grinding optical lenses for vehicle lighting, the lens clamps 804 on several groups of positioning plates 801 are controlled to clamp toward the corresponding optical lenses, so that the corresponding clamping gaskets 806 are in contact with the edge protrusions of the optical lenses. Then, several groups of positioning plates 801 are controlled to adjust the angles in the horizontal direction, so that several groups of optical lenses can enter the convex grinding mechanism 10 according to the corresponding angles. When performing the synchronous grinding of the concave and convex surfaces of the optical lenses, several groups of motor boxes 803 can be controlled to drive the corresponding guide gears 808 to rotate. Under the meshing connection relationship between the guide gear 808 and the guide rack 807, several groups of guide plates 805 can drive the optical lenses to rotate in the opposite direction of the concave grinding through the clamping gaskets 806, so as to prevent the optical lenses from being subjected to unidirectional stress and deformation caused by uneven temperature.

[0051] For example, Figure 6 and Figure 7 As shown, the convex surface grinding mechanism 10 includes a rotating disk 1001; a processing groove 1002 is opened on the top of the rotating disk 1001; a coupling 1004 is provided at the center of the bottom inner wall of the processing groove 1002; the coupling 1004 is transmission-connected to the output end of the driving mechanism 3; a plurality of groups of grinding grooves 1003 are sequentially provided on the bottom inner wall of the processing groove 1002; the top cross-section of each group of the grinding grooves 1003 is annular; a group of buffer pads 1005 is provided on the inner wall of each group of the grinding grooves 1003; a group of polishing pads 1006 is provided on the inner wall of each group of the buffer pads 1005; the inner wall of each group of the polishing pads 1006 is movably fitted on the convex outer wall of the optical lens.

[0052] When polishing and grinding optical lenses for vehicle lighting, according to the polishing requirements, the spin limit mechanism 8 is controlled to drive several groups of optical lenses into the corresponding grinding groove 1003, so that the convex outer walls of several groups of optical lenses are attached to the inner wall of the polishing pad 1006, and then several groups of concave grinding mechanisms 11 are controlled to extend into the concave surfaces of several groups of optical lenses, and then the spin limit mechanism 8 is controlled to drive several groups of optical lenses to rotate, and cooperate with the rotation of the rotating disk 1001. After the polishing liquid is injected into the polishing pad 1006, the convex and concave surfaces of several groups of optical lenses can be polished synchronously, and the polishing liquid produces relative movement with the optical lens under the rotation of the rotating disk 1001, thereby taking away the heat generated during the grinding process of the optical lens, while improving the processing effect of the optical lens, it can avoid the damage to the optical lens caused by high temperature.

[0053] For example, Figure 8As shown, the concave surface grinding mechanism 11 includes a guide ring 1101; the guide ring 1101 is sleeved on the outer wall of the mounting shaft 9; a first electric telescopic rod 1102 is provided on the outer wall of the guide ring 1101; the output end of the first electric telescopic rod 1102 is connected to a mounting plate 1103 in a transmission manner; a second electric telescopic rod 1104 is provided at the bottom center of the mounting plate 1103; the output end of the second electric telescopic rod 1104 is connected to a grinding motor 1105 in a transmission manner; the output end of the grinding motor 1105 is connected to a concave surface grinding head 1106 in a transmission manner; an anti-scratch filter component 1107 is provided on one side wall of the grinding motor 1105.

[0054] When polishing and grinding optical lenses for vehicle lighting, several groups of guide rings 1101 can be rotated and adjusted in direction on the outer wall of the mounting shaft 9, so that several groups of concave grinding heads 1106 can be respectively aligned with the concave surfaces of the corresponding optical lenses, and then several groups of second electric telescopic rods 1104 are controlled to drive the corresponding grinding motors 1105 to descend, so that several groups of concave grinding heads 1106 can respectively enter the concave surfaces of the corresponding optical lenses for polishing and grinding.

[0055] For example, Figure 9 As shown, the anti-scratch filter assembly 1107 includes a fixed plate 11071; several groups of connecting gas springs 11072 are provided at the bottom of the fixed plate 11071; a group of mounting rings 11073 are provided at the bottom of each group of connecting gas springs 11072; a group of universal balls 11074 are provided at both ends of each group of connecting gas springs 11072; each group of universal balls 11074 is hinged to a corresponding group of mounting rings 11073 or the bottom of the fixed plate 11071; a group of bellows 11075 is connected between two adjacent groups of mounting rings 11073; a magnetic filter 11076 is provided in a group of mounting rings 11073 away from the grinding motor 1105; and a group of filter membranes 11077 are provided in the remaining groups of mounting rings 11073 in turn.

During the polishing process of the optical lens, since several groups of optical lenses are polished synchronously and the polishing liquid flows relative to the optical lens, the magnetic filter 11076 and several groups of filter membranes 11077 arranged in the several groups of mounting rings 11073 can perform graded filtration of metal debris and glass debris in the polishing liquid, avoid affecting the polishing and grinding work of the optical lens behind the flow direction of the polishing liquid, and improve the quality of the polishing and grinding work of the optical lens.

[0057] By controlling the spin limit mechanism 8 to drive several groups of optical lenses into the corresponding grinding groove 1003, the convex outer walls of the several groups of optical lenses are attached to the inner wall of the polishing pad 1006, and then the several groups of concave grinding mechanisms 11 are controlled to extend into the concave surfaces of the several groups of optical lenses, and then the spin limit mechanism 8 is controlled to drive the several groups of optical lenses to rotate, and cooperate with the rotation of the rotating disk 1001. After the polishing liquid is injected into the polishing pad 1006, the convex and concave surfaces of the several groups of optical lenses can be polished synchronously, and the polishing liquid produces relative movement with the optical lens under the rotation of the rotating disk 1001, thereby taking away the heat generated during the grinding process of the optical lens, while improving the processing effect of the optical lens, it can avoid the damage to the optical lens caused by high temperature.

[0058] By controlling the lens clamps 804 on several groups of positioning plates 801 to clamp toward the corresponding optical lenses, the corresponding clamping gaskets 806 are made to contact the edge protrusions of the optical lenses. Then, the several groups of positioning plates 801 are controlled to adjust the angles in the horizontal direction, so that the several groups of optical lenses can enter the convex surface grinding mechanism 10 according to the corresponding angles. When performing the synchronous grinding of the concave and convex surfaces of the optical lenses, the several groups of guide plates 805 can be controlled to drive the optical lenses to rotate in the opposite direction of the concave surface grinding through the clamping gaskets 806, so as to avoid deformation of the optical lenses due to unidirectional stress caused by uneven temperature.

[0059] By controlling the descent of several groups of grinding motors 1105 and driving the fixed plate 11071 to descend at the same time, several groups of mounting rings 11073 can enter the grinding groove 1003 through the arc surface of the outer wall edge and fit on the inner wall of the polishing pad 1006. During the grinding process of the optical lens, since several groups of optical lenses are polished synchronously and the polishing liquid flows relative to the optical lens, the magnetic filter 11076 and several groups of filter membranes 11077 arranged in the several groups of mounting rings 11073 can grade and filter the metal debris and glass debris in the polishing liquid, avoid affecting the polishing and grinding work of the optical lens behind the flow direction of the polishing liquid, and improve the quality of the polishing and grinding work of the optical lens.

[0060] The optical lenses to be polished are placed in the loading conveyor 4 in sequence, and then the robotic arm 7 is controlled to drive the spin limit mechanism 8 to clamp several groups of optical lenses, and the several groups of optical lenses are transferred to the convex surface polishing mechanism 10, and then the several groups of concave surface polishing mechanisms 11 are controlled to enter the concave surface of the optical lens, so that the concave and convex surfaces of the optical lens can be polished synchronously. After the polishing and polishing work is completed, the robotic arm 7 and the spin limit mechanism 8 are controlled to transfer several groups of optical lenses to the unloading conveyor 5, and the loading conveyor 4 runs intermittently, while the unloading conveyor 5 runs continuously, so that the polishing and polishing work of the optical lens always remains continuous.

[0061] Based on the above-mentioned multi-surface polishing and grinding device for an optical lens for vehicle lighting, an embodiment of the present invention further proposes a polishing method for the multi-surface polishing and grinding device for an optical lens for vehicle lighting.
