Description

Technical Field

[0001] The utility model relates to the technical field of lens processing, in particular to an edge trimming device for optical lens processing. Background Art

[0002] Optical lenses go through rough grinding, fine grinding and polishing from blank to optical surface. After the initial molding of optical lenses, the edges of the lenses are prone to burrs and other defects during the processing. Therefore, the edges of the optical lenses need to be trimmed and ground.

[0003] After searching, the Chinese patent "An optical lens grinding and trimming device" authorization announcement number "CN218696982U" This optical lens grinding and trimming device, thanks to the cooperation of the lower clamping plate, the upper clamping plate and the rubber ring, can use the lower clamping plate and the upper clamping plate to clamp the optical lens, and use the rubber ring to abut the surface of the lens. Compared with the traditional clamping block, the contact area is wider, and when clamping the lens with a larger surface curvature angle, it can also maintain a sufficient contact area, thereby avoiding excessive force on the local lens during the clamping process and causing it to be damaged, that is, the clamping effect is improved;

[0004] The second cylinder and the grinding roller are fixedly mounted on the base, and their positions cannot be adjusted when trimming the optical lens. Meanwhile, when the corners of the optical lens are too large, the grinding roller cannot be adaptively adjusted, which may easily cause damage to the corners of the optical lens.

[0005] Therefore, an optical lens processing trimming device is proposed to solve the above problems. Utility Model Content

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions, a trimming device for optical lens processing, comprising:

[0008] A base, wherein a clamping mechanism is disposed in the middle of the top of the base, and polishing mechanisms are disposed on both sides of the top of the base;

[0009] The grinding mechanism includes a mounting cylinder provided at the top end of the base. One end of the mounting cylinder is rotatably connected to a threaded pipe.

[0011] Preferably, a limiting groove is provided at the top end of the mounting cylinder. A reference block is fixedly connected to the top end of the second moving plate. The top end of the reference block penetrates out of the limiting groove. A scale is fixedly connected to the top end of the mounting cylinder. The scale is in the shape of a "hui" character. The reference block and the scale are slidably connected. The mutual cooperation of the reference block and the scale can more intuitively observe the final debugging position of the second moving plate, provide a data reference for the limitation of the outermost edge of the grinding block, and improve the accuracy of adjustment.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-4 As shown, an edge trimming device for optical lens processing comprises:

[0025] A base 100, a clamping mechanism 300 is disposed in the middle of the top of the base 100, and grinding mechanisms 200 are disposed on both sides of the top of the base 100;

[0026] The grinding mechanism 200 includes a mounting tube 210 arranged at the top of the base 100, one end of the mounting tube 210 is rotatably connected to a threaded tube 220, one end of the threaded tube 220 passes through the mounting tube 210 and is threadedly connected to a screw rod 221, the other end of the screw rod 221 is rotatably connected to a first movable plate 222, the other side of the first movable plate 222 is fixedly connected to a second movable plate 223, the other side of the first movable plate 222 is fixedly connected to a spring 230, the other end of the spring 230 is fixedly connected to a mounting rod 240, the other end of the mounting rod 240 passes through the second movable plate 223 and the mounting tube 210 in sequence and is fixedly connected to a first motor 250, and the output shaft of the first motor 250 is fixedly connected to a grinding block 260.

[0027] like Figure 2 and Figure 3 As shown, a limiting groove 211 is provided at the top of the installation cylinder 210, and a reference block 226 is fixedly connected to the top of the second movable plate 223, and the top of the reference block 226 passes through the limiting groove 211. A scale 225 is fixedly connected to the top of the installation cylinder 210, and the scale 225 is in the shape of a "Hui" character, and the reference block 226 is slidably connected to the scale 225. When the second movable plate 223 moves, the reference block 226 will move synchronously with it, and the reference block 226 moves in the limiting groove 211 and the scale 225, so that the position of the second movable plate 223 can be observed more intuitively.

[0028] like Figure 2 and Figure 3 As shown, a resistance increasing sleeve is provided on the surface of the threaded tube 220, and an annularly distributed groove is provided on the surface of the resistance increasing sleeve. The resistance increasing sleeve can increase the friction between the palm and the threaded tube 220, and avoid slipping when the threaded tube 220 is rotated.

[0029] One side of the first movable plate 222 is fixedly connected to a limiting rod 224, and the other end of the limiting rod 224 passes through the mounting tube 210. When the first movable plate 222 moves, the limiting rod 224 can limit it, so that the first movable plate 222 can run along a predetermined route, improving the accuracy of adjustment.

[0030] like Figure 4 As shown, the clamping mechanism 300 includes a mounting seat 310 fixedly connected to the top of the base 100, a second motor 330 is embedded and installed in the mounting seat 310, a cylinder 320 is embedded and installed at the top of the mounting seat 310, and the telescopic end of the cylinder 320 and the output shaft of the second motor 330 are both fixedly connected with a clamping block 340. Contact washers are provided on the opposite sides of the two clamping blocks 340, and the contact washers are rubber components. First, place the optical lens that needs to be trimmed on the clamping block 340 below, start the cylinder 320, and the cylinder 320 drives the upper clamping block 340 to move downward. The two clamping blocks 340 are used to position and lock the optical lens. The sealing ring can directly contact the optical lens to protect the optical lens. At the same time, the second motor 330 is set to adjust the optical lens. The upper clamping block 340 and the optical lens are disengaged, and the second motor 330 will drive the lower clamping block 340 and the optical lens to rotate at the same time. In this method, the relative position of the lower clamping block 340 and the optical lens will not change, and there is no need to adjust the optical lens again.

[0031] Working principle: first place the optical lens that needs to be trimmed on the clamping block 340 below, start the cylinder 320, and the cylinder 320 drives the clamping block 340 above to move downward, and use the two clamping blocks 340 to position and lock the optical lens. After locking, rotate the threaded tube 220, and the screw rod 221 will drive the first movable plate 222 and the second movable plate 223 to move in the mounting tube 210. After adjusting to the final position where the optical lens needs to be trimmed, start the first motor 250, and the first motor 250 drives the grinding block 260 to grind the edge of the optical lens. If the edge angle is too large, the edge of the optical lens will squeeze the grinding block 260, thereby transmitting the force to the mounting rod 240, and the spring 230 will bend and be adaptively adjusted according to the contact force to avoid excessive grinding at one time and damage to the edge of the optical lens. When the mounting rod 240 is tightly fitted on the second movable plate 223 and continues to grind, the second motor 330 can be used to complete the final trimming of the optical lens.

[0032] It should be noted that the first motor 250, the cylinder 320 and the second motor 330 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the first motor 250, the cylinder 320 and the second motor 330 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
