[0018] like Figures 1 to 4 As shown, the lens holder 4 grinding device of this utility model includes: a first frame 1 and a second frame 2, the first frame 1 being able to move toward the second frame 2 along a first direction; a turntable 3, rotatably disposed on the first frame 1, used to fix the lens holder 4 to be ground, the turntable 3 being controlled to rotate by a first driving device disposed on the first frame 1; a contour grinding disc 5, rotatably disposed on the second frame 2 and controlled to rotate by a second driving device 6, the contour grinding disc 5 having a contoured surface adapted to the part of the lens holder 4 to be ground; and a dust collection component 7, disposed on the first frame 1 at the turntable 3, the dust collection component 7 being able to collect the particles generated during grinding.
[0019] See Figures 1 to 4 The lens holder 4 has two annular lugs to be ground and an inclined surface. Therefore, it needs to be ground and polished using a contour grinding disc 5 with a contoured surface that is compatible with it. The lens holder 4 is mounted on the first frame 1 via a turntable 3. The contour grinding disc 5 is rotatably mounted on the second frame 2. The first frame 1 is provided with a first drive device for driving the turntable 3 to rotate circumferentially. The first drive device can be a servo motor or a rotary cylinder. The second frame 2 is provided with a second drive device 6 for controlling the contour grinding disc 5 to rotate circumferentially. The second drive device 6 can be a pulley module controlled by a servo motor.
[0020] See Figure 1 The first frame 1 is configured to be able to approach or move away from the second frame 2 in a first direction so as to place the lens holder 4 on the first frame 1; in addition, in order to reduce the emission of dust particles generated after the lens holder 4 is ground, the first frame 1 is also provided with a dust suction component 7 for suctioning and collecting dust particles.
[0021] Specifically, when grinding and polishing the two annular lugs and one inclined surface of the lens holder 4, the lens holder 4 is first installed on the turntable 3 of the first bracket. Then, the first drive device controls the circumferential rotation of the lens holder 4 through the turntable 3, the second drive device 6 controls the rotation of the contour grinding disc 5, and the first frame 1 is controlled to move towards the second frame 2, so that the two annular lugs and the inclined surface of the lens holder 4 come into contact with the contour grinding disc 5. After the differentially rotating lens holder 4 comes into contact with the contour grinding disc 5, the contour grinding disc 5 can grind and polish the lens holder 4. By grinding the lens holder 4 by machining, the grinding quality, grinding precision and consistency of the lens holder 4 can be effectively improved.
[0022] In one or more embodiments, the second frame 2 is provided with a displacement component for controlling the movement of the first frame 1 along a first direction. The displacement component is a linear module or a lead screw module. The linear module can be of model ZM08-D1-G-S3A or ZM11-D1-G-S2A, and there is no specific limitation.
[0023] In one or more embodiments, the dust collection assembly 7 includes at least a fan, a first pipe and a second pipe connected to the inlet and outlet of the fan respectively, wherein the first pipe extends to the first frame 1 at the turntable 3, and the second pipe is connected to the collection device.
[0024] See Figure 1 The collection device can be a collection box; when the contour grinding disc 5 grinds and polishes the lens bracket 4, the debris generated on the surface of the lens bracket 4 will fall onto the first frame 1. At this time, the fan is controlled to work so that the dust particles on the surface of the first frame 1 are sucked out through the first pipe and the second pipe and stored in the collection device to reduce dust pollution.
[0025] In one or more embodiments, the first frame 1 is provided with a baffle plate 11 higher than the turntable 3 on the outer periphery of the turntable 3; the inner bottom surface of the first frame 1 is configured to be inclined toward the dust collection assembly 7 so that the ground powder particles can flow and accumulate toward the dust collection assembly 7.
[0026] See Figure 1 By providing a guide surface 12 facing the direction of the first tube on the bottom surface inside the first frame 1, and by providing a baffle plate 11 around the turntable 3 on the first frame 1, the risk of debris and dust particles spilling out during the grinding process can be further reduced.
[0027] In one or more embodiments, an antistatic coating is sprayed onto the surfaces of the first frame 1 and the second frame 2. This arrangement reduces the electrostatic adsorption of dust particles onto the surfaces of the first frame 1 and the second frame 2.
[0028] In one or more embodiments, the lens holder 4 is detachably mounted on the turntable 3 by means of a locking member; the locking member includes a locking screw and a pressing member 82 passing through the locking screw, wherein the locking screw can pass through the lens holder 4 and be threadedly connected to the turntable 3, and press the pressing member 82 against the lens holder 4.
[0029] See Figure 2 , Figure 3 The locking mechanism includes a locking bolt 81 and a pressing member 82, with the pressing member 82 fitted over the locking bolt 81. When installing the lens bracket 4 on the turntable 3, first, the pressing member 82 is fitted over the locking bolt 81, and then the lens bracket 4 is placed on the turntable 3, allowing the locking bolt 81 to pass through the lens bracket 4 and tighten onto the turntable 3. The pressing member 82 is pressed against the lens bracket 4 by the locking bolt 81, thus fixing the lens bracket 4 onto the turntable 3. This mechanism features a simple assembly and disassembly structure and convenient assembly and disassembly of the lens bracket 4, making it practical.
[0030] In one or more embodiments, the contour grinding disc 5 is detachably disposed at the output end of the second drive device 6. The contour grinding disc 5 can be mounted on the output end of the second drive device 6 using a six-head bolt, so that the contour grinding disc 5 can be quickly replaced when it wears out.
[0031] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
