[0001] The present invention relates to the technical field of optical lenses, and in particular to a disassembly device for optical lenses. 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; and wide-angle, standard, and telephoto lenses based on field of view.

[0003] The patent document with the authorization announcement number CN216561159U discloses a safe optical lens disassembly device, including a base plate and a clamp seat, the clamp seat is installed on the surface of the base plate, the base plate surface is fixedly connected to the bracket, the negative pressure tube is slidably inserted in the middle position of the bracket surface, the bottom end of the negative pressure tube is connected to the silicone suction cup, the upper surface of the silicone suction cup is fixedly connected to the lower surface of the bracket through a spring, the two side walls of the silicone suction cup are fixedly connected to the connecting rod, and the upper surface of the connecting rod is fixedly connected to the guide rod. Before disassembling the optical lens, the optical lens is placed on the surface of the base plate and clamped and fixed by the clamp seat. After the glass lens is separated relative to the lens housing, the silicone suction cup is pressed down longitudinally relative to the bracket. The spring is in an extended state within the elastic limit, and the air is sucked out by the negative pressure generator.

[0004] However, after the lens is released from the lens, it is easy for the lens to move and contact the inner wall of the lens barrel. For a long lens barrel, when a suction cup is used to move the lens out of the lens barrel, friction between the lens and the inner wall of the lens barrel is easy to occur, causing damage to the lens.

[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] like Figures 1 to 4 As shown, the optical lens disassembly device according to an embodiment of the present invention includes a base 1, a clamping assembly, a cylinder 3, a straw 4 and a positioning assembly.

[0028] For ease of understanding, the length direction of the base 1 is defined as the left-right direction.

[0029] like Figure 1 As shown, the clamping assembly can fix the lens barrel 91 and keep the lens barrel 91 in an inclined state. Specifically, the clamping assembly includes a support plate 21 and a plurality of clamping members 22. The support plate 21 is tilted and fixedly installed on the upper part of the base 1 and has an inclined surface facing the upper right side. The plurality of clamping members 22 are slidably installed on the inclined surface of the support plate 21 facing the upper right side. The plurality of clamping members 22 are arranged in an annular structure, and the clamping members 22 can slide radially along the annular structure. A driving structure 1 for driving the clamping members 22 to slide radially along the annular structure is provided on the support plate 21. After the lens barrel 91 is placed on the support plate 21, by controlling the driving structure 1, the plurality of clamping members 22 can be driven to move simultaneously in the inner direction of the annular structure and clamped on the outer peripheral side of the lens barrel 91, that is, the lens barrel 91 can be clamped and fixed, and the lens barrel 91 can be kept in an inclined state.

[0030] Among them, the driving structure 1 is an existing mature technology and will not be elaborated in detail here.

[0031] like Figure 1 As shown, the barrel 3 is tiltedly arranged on the upper part of the base 1 and can move along the tilting direction of the barrel 3. The tilting angle of the barrel 3 is the same as the tilting angle of the fixed lens barrel 91, and the two are arranged opposite each other. Specifically, a support frame 11 is fixedly installed on the upper part of the base 1, and the support frame 11 is located on the right side of the support plate 21. The barrel 3 is slidably installed on the support frame 11, and the barrel 3 is located in the upper right side direction of the fixed lens barrel 91. The center of the cross section of the barrel 3 and the center of the cross section of the fixed lens barrel 91 are on the same straight line. A driving structure 2 is provided on the support frame 11. By controlling the driving structure 2, the barrel 3 can be driven to move along the tilting direction of the barrel 3. Among them, the driving structure 2 is an existing mature technology and will not be elaborated in detail here.

[0032] like Figure 1 and Figure 2 As shown, the straw 4 passes through the barrel 3 and can move along the axial direction of the barrel 3. The length direction of the straw 4 is in the same direction as the axial direction of the barrel 3. The barrel 3 is provided with a slide groove 31 for the straw 4 to move radially along the barrel 3. When the straw 4 moves along the slide groove 31 to the extreme position of one side end, the straw 4 is located at the center of the cross section of the barrel 3, and a suction cup 41 is provided at the inclined lower end of the straw 4.

[0033] The cam 72 is engaged with the stopper 72 and is adapted to move the stopper 72 in the radial direction of the cylinder 3 so as to prevent the cam 72 from moving in the opposite direction.

[0034] The lower left end of the straw 4 extends out from the lower left end face of the barrel 3, and the suction cup 41 is installed at the lower left end of the straw 4. The upper right end of the straw 4 is used to connect with a negative pressure suction device (not shown in the figure). After the suction cup 41 is in contact with the lens 92, the negative pressure suction device is controlled to adsorb the lens 92 through the suction cup 41.

[0035] like Figures 1 to 3 As shown, the positioning assembly includes a positioning rod 1 51 and a positioning rod 2 52. The positioning rod 1 51 is slidably set at a lower side position of the inclined lower end of the cylinder 3 and can move radially along the cylinder 3. The positioning rod 2 52 is slidably set at an upper side position of the inclined lower end of the cylinder 3 and can move radially along the cylinder 3. The positioning rod 2 52 is in the same direction as the positioning rod 1 51. When the positioning rod 2 52 moves toward the positioning rod 1 51, the straw 4 can remain in the middle position between the positioning rod 1 51 and the positioning rod 2 52.

[0036] Specifically, a slide groove 2 32 is provided on the lower left end face of the cylinder 3, and the slide groove 2 32 extends along the radial direction of the cylinder 3 and is opposite to the slide groove 1 31. The positioning rod 1 51 and the positioning rod 2 52 are both slidably installed at the slide groove 2 32, and the positioning rod 1 51 and the positioning rod 2 52 are respectively located on both sides of the center of the circle of the lower left end face of the cylinder 3, and the positioning rod 2 52 is located on the upper left side of the positioning rod 1 51, and the length of the positioning rod 2 52 is greater than the length of the positioning rod 1 51.

[0037] The positioning assembly also includes a slider 53 and a connecting rod 56. The slider 53 is slidably installed at the inclined lower end of the cylinder 3 and can slide radially along the cylinder 3. The slider 53 is located at the front side of the straw 4. The sliding direction of the slider 53 is perpendicular to the length direction of the slide groove 32. The positioning rod 51 is fixedly connected to the fixing rod 62. The two ends of the connecting rod 56 are hinged to the slider 53 and the fixing rod 62 respectively. A positioning plate 81 is also fixedly installed at the inclined lower end of the cylinder 3. The positioning plate 81 is threadedly connected to a screw 82. The screw 82 is rotatably connected to the slider 53. Therefore, by controlling the rotation of the screw 82, the slider 53 can be driven to approach or move away from the straw 4. At the same time, the positioning rod 51 can be driven to slide in the slide groove 31 through the connecting rod 56.

[0038] The positioning assembly also includes a slider 2 54, a slider 3 55, a connecting rod 2 57 and a connecting rod 3 58. The slider 2 54 is slidably installed at the lower left end of the cylinder 3 and is located on one side of the slider 1 53. The slider 2 54 can move in a first direction and a second direction. The first direction is parallel to the sliding direction of the slider 1 53, and the second direction is perpendicular to the first direction. The slider 3 55 is arranged at the lower left end of the cylinder 3. The positioning plate 81 is also threadedly connected with a screw 2 83. The screw 2 83 is parallel to the screw 1 82. The screw 2 83 is connected to the slider 3 55 for rotation. The rotation of the screw 2 83 can drive the slider 3 55 to move, and the movement direction of the slider 3 55 is controlled. The second direction is in the same direction as the sliding direction of slider one 53, the length direction of slider three 55 is perpendicular to the sliding direction of slider one 53, slider two 54 is slidably connected to slider three 55, and can slide along the length direction of slider three 55, that is, the second direction is in the same direction as the length direction of slider three 55, the two ends of connecting rod two 57 are respectively hinged to positioning rod one 51 and slider two 54, and the two ends of connecting rod three 58 are respectively hinged to positioning rod two 52 and slider two 54, so that when the control screw two 83 rotates, it can drive slider two 54 and slider three 55 to approach or move away from the straw 4, and at the same time, it can make the positioning rod one 51 and the positioning rod two 52 approach or move away from each other.

[0039] like Figure 2 As shown, the positioning assembly also includes a blocking rod 59, which is fixedly connected to the slider 2 54 and is arranged on one side of the straw 4. The blocking rod 59 can move synchronously with the slider 2 54, and when the blocking rod 59 moves with the slider 2 54, the straw 4 can be located on the bisector of the angle formed by the connecting rod 2 57 and the connecting rod 3 58.

[0040] like Figure 2As shown, the inclined lower end of the cylinder 3 is provided with two slide grooves 33, and the two slide grooves 33 are symmetrically distributed on both sides of the slide groove 2 32. There is an angle between the slide groove 33 and the slide groove 2 32. The positioning assembly also includes two positioning rods 3 60 and two telescopic members 61. The two positioning rods 3 60 are respectively slidably installed at the two slide grooves 33, and the two telescopic members 61 are respectively arranged between the positioning rod 2 52 and the two positioning rods 3 60. The two ends of the telescopic member 61 are rotatably connected with the positioning rod 3 60 and the positioning rod 2 52, and a torsion spring (not shown in the figure) is connected at the rotation connection between the telescopic member 61 and the positioning rod 2 52, and the two ends of the torsion spring are respectively fixedly connected with the telescopic member 61 and the positioning rod 2 52. The torsion spring makes the positioning rod 3 60 closer to the straw 4 than the positioning rod 2 52.

[0041] When disassembling the lens 92, first place the lens barrel 91 on the support plate 21 and fix the lens barrel 91 by means of a plurality of clamps 22. Since the lens barrel 91 is in a state where the right end is tilted upward, the lens 92 in the lens barrel 91 will slide to the lower right after being released, and the lower right side of the lens 92 will abut against the inner wall of the lens barrel 91. There will be a gap 93 between the upper left side of the lens 92 and the inner wall of the lens barrel 91. Next, the barrel body 3 is controlled to move to the lower left, and the positioning rod 1 51, the positioning rod 2 52 and the positioning rod 3 60 will move synchronously with the barrel body 3. After the positioning rod 1 51 is extended into the lens barrel 91, the screw rod 1 82 is controlled to rotate to move the slider 1 53 toward the direction close to the straw 4, and the positioning rod 1 51 will be pushed away from the straw 4 by the connecting rod 1 56. , until the positioning rod 1 51 stops against the inner wall of the lens barrel 91, and then the control screw 2 83 rotates to make the slider 3 55 and the slider 2 54 move in the direction close to the straw 4. Since the position of the positioning rod 1 51 will remain unchanged at this time, the position of the connecting rod 2 57 will also remain unchanged. When the slider 2 54 moves in the direction close to the straw 4, the positioning rod 2 52 will move in the direction away from the straw 4, and the slider 2 54 will slide along the slider 3 55 to make the blocking rod 59 move in the direction away from the positioning rod 1 51. At this time, the straw 4 will move to the center position of the barrel 3 under the push of the elastic member 71, and in this process, the straw 4 is always on the bisector of the angle formed by the connecting rod 2 57 and the connecting rod 3 58, and the straw 4 and the blocking rod 59 remain in a stopped state.

[0042] Next, the barrel 3 is controlled to move downward to the left. After the positioning rod 2 52 and the positioning rod 3 60 move to the gap 93 formed between the upper left side of the lens 92 and the inner wall of the lens barrel 91, the screw 2 83 is controlled to rotate to make the slider 3 55 and the slider 2 54 move away from the straw 4. The slider 2 54 will move along the length direction of the slider 3 55 and drive the positioning rod 2 52 to move. The blocking rod 59 and the straw 4 will move synchronously with the slider 2 54, so that the positioning rod 2 52, the blocking rod 59 and the straw 4 will gradually approach the positioning rod 1 51, and the straw 4 will gradually deviate from the center of the barrel 3. The elastic member 71 will be compressed. When the positioning rod 2 52 gradually moves toward the positioning rod 1 51, the telescopic member 61 and the torsion spring will drive The two positioning rods three 60 move inward, and the two positioning rods three 60 will first contact the outer peripheral surface of the lens 92. As the positioning rod two 52 continues to move, the two positioning rods three 60 will correct the position of the lens 92 until the positioning rod two 52 and the outer peripheral surface of the lens 92 stop, which can ensure that the stop position of the positioning rod two 52 and the lens 92 and the stop position of the lower side of the lens 92 and the inner wall of the lens barrel 91 are symmetrical with the center of the lens 92. Since the suction tube 4 is located on the angular bisector of the connecting rod two 57 and the connecting rod three 58, the suction tube 4 will correspond to the center of the lens 92. Then the suction tube 4 is controlled to move until the suction cup 41 is in contact with the lens 92, and the negative pressure suction device is controlled to adsorb and fix the lens 92 through the suction cup 41.

[0043] Then continue to control the rotation of screw rod 2 83 to move slider 3 55 and slider 2 54 toward the direction of straw 4, positioning rod 2 52 and blocking rod 59 will move toward the direction away from straw 4, positioning rod 2 52 will no longer stop lens 92, blocking rod 59 will no longer restrict straw 4, and straw 4 will move to the center of barrel 3 under the action of elastic member 71 in compression, and lens 92 will move synchronously with straw 4 and move to the center of lens barrel 91. At this time, the outer peripheral surface of lens 92 will not contact the inner wall of lens barrel 91. Finally, control barrel 3 and straw 4 to move to the upper right, so that lens 92 can be taken out of lens barrel 91.

[0044] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
