DETAILED DESCRIPTION

[0025] In order to make the personnel in the art better understand the scheme of the present application, the technical scheme in the specific embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application.

[0026] As shown in Figure 1 , Figure 2 and Figure 3 , the present application provides a lens edging machine 100 with a notch milling and positioning function, which comprises a machine frame 11, a fixing mechanism 12, an edging mechanism 13, a positioning mechanism 14 and a notch milling mechanism 15.

[0027] Specifically, the machine frame 11 comprises a fixedly connected upper support plate 111 and a lower support plate 112, and an installation space for installing the fixing mechanism 12, the edging mechanism 13, the positioning mechanism 14 and the notch milling mechanism 15 is formed between the upper support plate 111 and the lower support plate 112.

[0028] The fixing mechanism 12 is used to fix the lens and drive the lens to rotate, so as to cooperate with the edging mechanism 13 to complete the edging of the periphery of the lens. The fixing mechanism 12 comprises an upper spindle 121 and a lower spindle 122. The upper spindle 121 comprises an upper press wheel 1211 rotationally connected with the rack 11, and the lower spindle 122 comprises a lower press wheel 1221 rotationally connected with the rack 11. The rotation shafts of the upper spindle 121 and the lower spindle 122 coincide and are in the vertical direction. The upper press wheel 1211 and the lower press wheel 1221 clamp and fix the lens and drive the lens to rotate.

[0029] At least one of the upper press wheel 1211 and the lower press wheel 1221 is connected with a spindle lifting component, which is used to drive the upper press wheel 1211 and / or the lower press wheel 1221 to lift, so that the upper press wheel 1211 and the lower press wheel 1221 can be relatively opened and pressed. When the upper press wheel 1211 and the lower press wheel 1221 are relatively opened, the lens is placed on the lower press wheel 1221; when the upper press wheel 1211 and the lower press wheel 1221 are relatively pressed, the lens is fixed between the upper press wheel 1211 and the lower press wheel 1221. In the present application, the upper press wheel 1211 is connected with the spindle lifting component (the spindle lifting component is not shown in the spindle lifting component), which is a lifting motor or the like. Figure 1 、 Figure 2

[0030] At least one of the upper press wheel 1211 and the lower press wheel 1221 is connected with a spindle rotating component, which is used to drive the upper press wheel 1211 and / or the lower press wheel 1221 to rotate, so that the upper press wheel 1211 and / or the lower press wheel 1221 can drive the lens to rotate after clamping and fixing the lens. In the present application, the lower press wheel 1221 is connected with the spindle rotating component (the spindle rotating component is arranged in the cabinet below the spindle rotating component), which is a rotating motor or the like. Figure 1 、 Figure 2

[0031] The edging mechanism 13 is used to edge the lens. The edging mechanism 13 comprises a cutter 131 and a cutter feeding and retreating driving component 132. The cutter feeding and retreating driving component 132 is installed on the rack 11, and the cutter feeding and retreating driving component 132 is connected with the cutter 131 to drive the cutter 131 to feed and retreat. The cutter feeding and retreating driving component 132 drives the cutter 131 to feed, so that the cutter 131 contacts the outer peripheral edge of the lens. During the rotation of the lens, the cutter 131 completes the edging of the outer peripheral edge of the lens.

[0032] ​​The positioning mechanism 14 is used for positioning the lens, so that the center of the lens is located on the rotation shafts of the upper pressing wheel 1211 and the lower pressing wheel 1221, thereby enabling the turning tool 131 to move along the outer peripheral edge of the lens during the turning of the lens. The positioning mechanism 14 comprises two positioning clamps 141 and a clamp opening and closing driving part 142. The clamp opening and closing driving part 142 is installed on the rack 11, and the clamp opening and closing driving part 142 is connected with the two positioning clamps 141 to drive the two positioning clamps 141 to open and close. The clamping of the lens by the two positioning clamps 141 enables the center of the lens to move to the rotation shafts of the upper pressing wheel 1211 and the lower pressing wheel 1221.

[0033] The notch milling mechanism 15 is used for milling the positioning notch for determining the direction of the polarizing line of the lens, and the notch milling mechanism 15 comprises a milling tool 151 and a milling tool feeding and retracting driving part 152. The milling tool feeding and retracting driving part 152 is installed on the rack 11, and the milling tool feeding and retracting driving part 152 is connected with the milling tool 151 to drive the milling tool 151 to feed and retract. The feeding of the milling tool 151 by the milling tool feeding and retracting driving part 152 enables the milling tool 151 to mill the positioning notch at the edge of the lens.

[0034] The working principle of the lens turning machine 100 is as follows: the lens is first placed on the lower pressing wheel 1221, and then the lens is positioned by the positioning mechanism 14, and then the lens is pressed and fixed by the upper pressing wheel 1211 and the lower pressing wheel 1221 of the fixing mechanism 12. The fixing mechanism 12 drives the lens to rotate, and the turning mechanism 13 performs the turning work on the lens. When the turning of the lens is completed, the turning mechanism 13 is reset, and then the milling notch mechanism 15 mills the positioning notch at the edge of the lens.

[0035] Through the above arrangement, the lens does not need to be taken off from the fixing mechanism 12 for milling the notch, and thus the turning and milling of the positioning notch of the lens can be realized only by one-time positioning and clamping, thereby effectively improving the yield of the polarizing lens and other lenses, and the positioning of the polarizing line and the central axis direction is not prone to deviation

[0036] As Figure 3 and Figure 4As shown, as an implementation manner, the notching mechanism 15 further comprises a milling cutter sliding seat 153, a milling cutter angle adjusting seat 154, and a plurality of milling cutter feeding and retracting guide rods 155. The milling cutter sliding seat 153 is in sliding connection with the plurality of milling cutter feeding and retracting guide rods 155, and the milling cutter feeding and retracting guide rods 155 play a guiding role on the milling cutter sliding seat 153, so that the feeding and retracting of the milling cutter 151 is more stable. The milling cutter angle adjusting seat 154 is installed on the milling cutter sliding seat 153, and the milling cutter angle adjusting seat 154 is connected with the milling cutter 151 to adjust the angle of the rotation shaft of the milling cutter head of the milling cutter 151 relative to the feeding and retracting direction of the milling cutter 151. The lens has a certain curvature, and since the middle part of the lens is horizontally placed, the edge part of the lens will be inclined at a certain angle relative to the middle part. The edge part of different models of lenses is inclined at different angles relative to the middle part. Therefore, the present application adjusts the angle of the milling cutter 151 through the milling cutter angle adjusting seat 154, so that the angle of the milling cutter head is adapted to the angle of the edge part of the lens.

[0037] Specifically, the milling cutter angle adjusting seat 154 comprises a fixed seat and a rotating seat. The fixed seat is fixedly connected with the milling cutter sliding seat 153, and the fixed seat is provided with a fan-shaped angle adjusting groove. The rotating seat is rotatably connected on the angle adjusting groove of the fixed seat, the milling cutter 151 is fixedly connected on the rotating seat, and the rotating seat and the fixed seat are fixedly connected by bolts. By adjusting the mounting position of the rotating seat in the angle adjusting groove of the fixed seat, the mounting angle of the milling cutter 151 can be adjusted.

[0038] It should be noted that the angle of the milling cutter head is adapted to the angle of the edge part of the lens, which means that when the milling cutter 151 is milling the lens, the rotation shaft of the milling cutter head is perpendicular to the upper surface of the milled edge part of the lens.

[0039] As shown in the drawings, Figure 5 As an implementation manner, the turning tool 131 comprises a turning tool head 1311, a turning tool head angle adjusting seat 1312, and a turning tool holder 1313, and the turning tool head 1311 is fixedly installed on the turning tool head angle adjusting seat 1312. The turning tool holder 1313 is provided with a mounting shaft 1313a, the turning tool head angle adjusting seat 1312 is installed on the mounting shaft 1313a, the turning tool head angle adjusting seat 1312 is provided with a plurality of fixed pin holes 1312a in the circumferential direction, and the axis of the fixed pin hole 1312a passes through the axis of the mounting shaft 1313a. The turning tool holder 1313 is provided with a fixed pin (not shown in the drawings), and the fixed pin is inserted into one of the fixed pin holes 1312a to fix the turning tool holder 1313 relative to the turning tool head angle adjusting seat 1312. By inserting the fixed pin into different fixed pin holes 1312a, the angle of the turning tool head 1311 can be adjusted, so that the angle of the turning tool head 1311 is adapted to the angle of the edge part of the lens. Figure 5

[0040] ​It should be noted that the angle of the tool bit 1311 is adapted to the angle of the edge portion of the lens means that the cutting edge of the tool bit 1311 is in the shape of a circular arc, so that the tool 131 carves the outer edge of the lens into an arc shape, and thus the middle of the cutting edge of the tool bit 1311 is aligned with the middle of the outer edge of the lens when the tool bit 1311 carves the lens.

[0041] Specifically, the tool holder 1313 is provided with a fixed pin guide groove 1313b, and a fixed pin is slidingly connected in the fixed pin guide groove 1313b so as to be inserted into and pulled out of the fixed pin hole 1312a. The provision of the fixed pin guide groove 1313b allows the fixed pin to be inserted into and pulled out of the fixed pin hole 1312a along the length direction of the fixed pin hole 1312a, thereby avoiding difficulty in inserting the fixed pin into the fixed pin hole 1312a or jamming of the fixed pin in the fixed pin hole 1312a.

[0042] Specifically, the tool holder 1313 is provided with a fixed pin guide groove 1313b, and a fixed pin is slidingly connected in the fixed pin guide groove 1313b so as to be inserted into and pulled out of the fixed pin hole 1312a. The provision of the fixed pin guide groove 1313b allows the fixed pin to be inserted into and pulled out of the fixed pin hole 1312a along the length direction of the fixed pin hole 1312a, thereby avoiding difficulty in inserting the fixed pin into the fixed pin hole 1312a or jamming of the fixed pin in the fixed pin hole 1312a.

[0043] More specifically, the tool lifting driving component includes a tool lifting plate 133, a lifting screw 134, and a plurality of tool lifting guide columns 135. The lower end of the lifting screw 134 is connected to the tool lifting plate 133, and the lifting screw 134 and the tool lifting plate 133 have a rotational freedom degree of relative rotation therebetween, and the freedom degree of relative movement therebetween in the up-down direction is constrained. The upper end of the lifting screw 134 is threadedly connected to the tool lifting plate 133. The upper end of the tool lifting guide column 135 is provided through the upper support plate 111, and the lower end of the tool lifting guide column 135 is fixedly connected to the tool lifting plate 133. The tool 131 and the tool feeding and retracting driving component 132 are installed on the tool lifting plate 133. The height position of the tool lifting plate 133 can be adjusted by manually rotating the lifting screw 134, or the height position of the tool lifting plate 133 can be adjusted by connecting the lifting screw 134 to a lifting motor to drive the lifting screw 134 to rotate.

[0044] As an implementation manner, the notching mechanism 15 further comprises a first limiting baffle 156 and a second limiting baffle 157. The first limiting baffle 156 is fixedly connected with the rack 11, and the second limiting baffle 157 is fixedly connected with the milling cutter sliding seat 153. The first limiting baffle 156 is arranged on the side close to the fixing mechanism 12 relative to the second limiting baffle 157. When the milling cutter 151 feeds, the second limiting baffle 157 moves with the milling cutter sliding seat 153, and when the second limiting baffle 157 contacts the first limiting baffle 156, the milling cutter 151 cannot continue to feed. The first limiting baffle 156 and the second limiting baffle 157 are used to limit the maximum stroke of the milling cutter 151 feeding, so as to avoid that the milling cutter 151 feeds too deep and causes damage to the lens.

[0045] As an implementation manner, the lens edging machine 100 with the notching function further comprises a dust collecting component 16. The dust collecting component 16 is used to collect the debris generated in the lens edging, and at least partially surrounds the outer periphery of the turning tool 131. The dust collecting component 16 forms a dust collecting space in the inside, and is connected with a dust collecting pipeline 17 which communicates with the dust collecting space. In the present application, two lens edging positions are arranged to improve the working efficiency of the lens edging, Figure 1 、 Figure 2 The dust collecting component 16 of one lens edging position is omitted in the present application.

[0046] As an implementation manner, the positioning mechanism 14 and the edging mechanism 13 are respectively arranged on the front side and the rear side of the fixing mechanism 12, and the notching mechanism 15 is provided with two groups. The two groups of notching mechanisms 15 are respectively arranged on the left side and the right side of the fixing mechanism 12. Through the above arrangement, the compactness of the lens edging machine 100 is improved, so as to reduce the occupied space of the lens edging machine 100. In addition, through the arrangement of the two groups of notching mechanisms 15, the working efficiency of the lens notching is improved.

[0047] As an optional implementation manner, the positioning clamping jaw 141 comprises a positioning clamping arm 1411 and two positioning columns 1412. The positioning clamping arm 1411 has an arc-shaped positioning surface 1411a matched with the upper spindle 121 or the lower spindle 122, and the two positioning columns 1412 are fixedly installed on the positioning clamping arm 1411. In the present application, the positioning clamping arm 1411 has the arc-shaped positioning surface 1411a matched with the lower spindle 122. After the two positioning clamping jaws 141 are clamped, the arc-shaped positioning surface 1411a of the positioning clamping arm 1411 is matched with the lower spindle 122. On one hand, the arc-shaped positioning surface 1411a plays a limiting role, so as to prevent the positioning clamping jaw 141 from being clamped too tightly and causing damage to the lens. On the other hand, the arc-shaped positioning surface 1411a plays a center positioning role, so as to make the center axes of the two positioning clamping jaws 141 coincide with the axis of the lower spindle 122. In addition, the four positioning columns 1412 of the two positioning clamping jaws 141 abut against the outer peripheral edge of the lens, so as to make the center of the lens coincide with the axis of the spindle.

[0048] As another optional implementation, the positioning clamping jaw 141 comprises a positioning clamping arm 1411 having a V-shaped positioning surface facing the fixing mechanism 12. After clamping by the two positioning clamping jaws 141, the V-shaped positioning surfaces of the two positioning clamping arms 1411 abut against the outer peripheral edge of the lens, so that the center of the lens coincides with the axis of the main shaft.

[0049] As an implementation, the upper surface of the lower pressing wheel 1221 is concave curved surface shape, the lower section of the upper pressing wheel 1211 is provided with a flexible buffer pad 1211a, the lower surface of the flexible buffer pad 1211a is convex curved surface shape. In this application, the flexible buffer pad 1211a is made of rubber material or the like. Through the above setting, the part of the lower pressing wheel 1221 and the upper pressing wheel 1211 contacting with the lens is matched with the arc surface of the lens, so that the lens is fixed more stably. In addition, the flexible buffer pad 1211a plays a buffering role when the fixing mechanism 12 fixes the lens, so as to avoid damage to the lens due to the impact of the upper pressing wheel 1211 or the excessive pressing force of the upper pressing wheel 1211 and the lower pressing wheel 1221.

[0050] The lens edging machine 100 with the lens positioning notch milling function of the present application has the following working principle:

[0051] 1. Place the lens on the lower pressing wheel 1221;

[0052] 2. Position the lens by the positioning mechanism 14, so that the center of the lens coincides with the axis of the lower pressing wheel 1221;

[0053] 3. The main shaft lifting part drives the upper pressing wheel 1211 to descend, and the upper pressing wheel 1211 and the lower pressing wheel 1221 of the fixing mechanism 12 press and fix the lens;

[0054] 4. The tool bit feeding and retracting driving part 132 drives the tool bit 131 to feed, and the lens edging mechanism 13 performs lens edging. At this time, the main shaft rotating part drives the lower main shaft 122 to rotate, so as to drive the lens to rotate, and the upper main shaft 121 rotates with the lens to complete the lens edge edging;

[0055] 5. The milling cutter feeding and retracting driving part 152 drives the milling cutter 151 to feed, and the notch milling mechanism 15 mills the positioning notch on the edge of the lens.
