[0029] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0030] In the description of the embodiments of the present disclosure, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0031] As mentioned above, optical lens core extraction machines mostly use ordinary motors when grinding lenses, and the speed is within 3000rad / min. The lens processing efficiency and processing accuracy are low, which cannot meet the needs of high-speed lens processing. In the related prior art, the rotation of the workpiece axis of the core extraction machine usually uses a motor to drive the fixed axis and the movable axis to rotate at the same time. The centering speed is low and the transmission mechanism is complex, resulting in poor centering effect and high equipment maintenance costs. It cannot meet the application scenarios of high-speed and high-stability centering. In addition, the movement of the movable axis is controlled by the pneumatic system, which is prone to unstable air pressure, resulting in unstable clamping force of the lens and poor centering effect of the guide rail lens.

[0032] In view of this, the embodiment of the present disclosure provides an optical lens core extracting machine, in which the fixed axis and the movable axis are driven by separate motors, which can meet the needs of high-speed, high-precision, and high-stability lens core extracting. The principle of the drawer assembly according to the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0033] Figure 1 FIG. 1 shows a perspective view of an optical lens core extraction machine 10 according to an embodiment of the present disclosure, as shown in FIG. Figure 1 As shown, the base 101 of the optical lens core extracting machine 10 can be a box-like structure, and an embedded electric cabinet for various electrical components for realizing the functions of the optical lens core extracting machine is set on the front side of the box of the base 101, and embedded cabinets for installing lubrication pumps, pneumatic components, etc. are set on the left and right sides of the box. The upper end surface of the box of the base 101 is provided with a wire groove and a wire hole, which is convenient for threading the wires to the electric cabinet in the box. The base 101 is provided with a lens clamp 103 for clamping the lens to be processed, a grindstone assembly 104 for grinding and coring the lens, a feeding assembly 105, and a control panel 106 for operating the optical lens core extracting machine.

[0034] Figure 2 A perspective view of a lens fixture 103 of an optical lens core removal machine 10 according to an embodiment of the present disclosure is shown. Figure 2As shown, in one or more embodiments of the present disclosure, the lens fixture 103 includes a fixed shaft assembly and a movable shaft assembly that cooperate with each other to clamp the lens a to be processed, and a movable shaft driving assembly for driving the movable shaft assembly to approach or move away from the fixed shaft, thereby clamping or loosening the lens to be processed. Wherein, the position of the fixed shaft assembly is immovable, and it includes a fixed shaft for fixing the lens a to be processed and a first motor 1311 for driving the fixed shaft to rotate. The movable shaft assembly includes a movable shaft coaxially arranged with the fixed shaft and a second motor 1321 for driving the movable shaft to rotate, and the movable shaft driving assembly is used to drive the movable shaft assembly to move along the axial direction of the movable shaft, thereby approaching or moving away from the fixed shaft, so as to achieve the clamping or loosening of the lens a to be processed located between the fixed shaft and the movable shaft. The movable shaft driving assembly includes a screw pair 1331 and a third motor 1332 for driving the screw of the screw pair 1331 to rotate. The screw pair includes a pair of transmission elements consisting of a screw and a nut, which can convert the rotational motion of the screw into the linear motion of the nut. In one or more embodiments of the present disclosure, the screw is parallel to the axial arrangement of the movable shaft in the movable shaft assembly, and the nut of the screw pair 1331 is fixed to the movable shaft assembly, so that the third motor 1322 can drive the nut on the screw to move along the length direction of the screw by driving the screw to rotate, thereby driving the movable shaft assembly fixed with the nut to move as a whole, so that the movable shaft approaches or moves away from the fixed shaft. During the core extraction process, the feed assembly 105 of the optical lens core extraction machine transports the lens a to be processed to the lens fixture 103, and fixes it with the fixed shaft of the fixed shaft assembly. The third motor 1332 of the movable shaft driving assembly drives the screw pair 1331 to move, so that the nut of the screw pair drives the movable shaft driving assembly to approach the fixed shaft and clamp the lens a to be processed, and the first motor 1311 and the second motor 1321 respectively drive the fixed shaft and the movable shaft to rotate, so as to center the lens a to be processed. Subsequently, the grinding stone assembly 104 performs edge grinding and core extraction on the lens a to be processed.

[0035] In this way, the fixed shaft and the movable shaft are driven by separate motors respectively. Compared with the method in the related prior art where one motor drives the fixed shaft and the movable shaft to rotate at the same time, the transmission structure is simpler and the high-speed centering function is easy to achieve. In addition, by driving the screw pair by the motor to drive the entire movable shaft assembly to move, the stability of the movement of the movable shaft assembly and the accurate control of the position of the movable shaft can be improved, thereby achieving high-stability centering.

[0036] In one or more embodiments of the present disclosure, the first motor 1311 and the second motor 1321 can be connected to the corresponding shaft by any same or different transmission mode, as long as the corresponding shaft can be driven to rotate. The transmission mode may include, but is not limited to, one or more of a gear transmission connection, a belt transmission connection, a chain transmission connection, and a coupling connection. In one or more embodiments of the present disclosure, the first motor 1311 can also drive the fixed shaft to rotate through a coupling. Similarly, the second motor 1321 can also drive the movable shaft to rotate through a coupling. The coupling has the advantages of simple structure and good transmission rigidity, and is more suitable for high-speed and high-precision application scenarios.

[0037] In one or more embodiments of the present disclosure, the optical lens core extraction machine further includes a marble mount. Figure 3 1 is a perspective view of a marble mount of an optical lens core extracting machine 10 according to an embodiment of the present disclosure. Figure 3 As shown, a marble mount 102 can also be provided on the base 101 of the optical lens core extracting machine 10, and the lens fixture 103 and the grindstone assembly 104 can be provided on the base 101 through the marble mount 102. Marble has high manufacturing accuracy, stability and corrosion resistance, and can minimize the deformation of the castings in the lens fixture 103 and the grindstone assembly 104, so that the optoelectronic lens core extracting machine can have higher accuracy and stability. In one or more embodiments of the present disclosure, the lens fixture 103 also includes a fixture box 134 provided on the marble mount 102, and the fixture box 134 has two through holes spaced apart, namely a first through hole for the fixed shaft to pass through and a second through hole for the movable shaft to pass through. The first through hole and the second through hole are coaxially arranged, so that the fixed shaft and the movable shaft installed in the two through holes can also remain coaxial. In one or more embodiments of the present disclosure, an oil groove for lubricating oil circulation is provided on the inner wall of the second through hole, and lubricating oil can be injected into the oil groove of the second through hole by a lubrication pump, and the lubricating oil flows into the gap between the inner wall of the through hole and the outer periphery of the shaft through the oil groove. When the movable shaft driving assembly drives the movable shaft assembly to move, the movable shaft will move linearly in the second through hole, and the injected lubricating oil can reduce the friction of the movable shaft when it moves, so that the movable shaft moves more smoothly.

[0038] Figure 4 1 is a perspective view showing a fixed shaft assembly 131 of a lens holder according to an embodiment of the present disclosure. Figure 4As shown, in one or more embodiments of the present disclosure, the fixed shaft assembly 131 also includes a motor mounting seat 1313 disposed on the fixture box 134, and the first motor 1311 is fixed on the fixture box 134 through the motor mounting seat 1313, and the output end of the first motor 1311 is connected to the fixed shaft 1312 through a coupling, so that the first motor can drive the fixed shaft 1312 to rotate in the first through hole. The end of the fixed shaft is provided with a lens fixing structure for fixing the lens to be processed. For example, the lens fixing structure can be a suction head for fixing the lens based on vacuum adsorption at the end of the fixed shaft, and the lens fixing structure can also be a structure that uses mechanical parts (such as positioning pins, V-blocks, reference surfaces, etc.) to contact the lens and fix the lens through mechanical constraints. In one or more embodiments of the present disclosure, the fixed shaft assembly 133 also includes a limiting structure 1314 for limiting the fixed shaft in the axial direction of the fixed shaft 1312. The limiting structure can be any structure or design that can limit the axial position of the fixed shaft 1312 and does not affect the rotation of the fixed shaft. Figure 5 13 is a perspective view showing a positioning structure 1314 according to an embodiment of the present disclosure. Figure 5 As shown, in one or more embodiments of the present disclosure, the limiting structure 1314 may include a clamping block mounting hole 1314a provided on the clamp box 134 and two clamping blocks 1314b placed in the mounting hole 1314a. The two clamping blocks 1314b have similar structures and both have arc surfaces for splicing and cooperating with each other to clamp the fixed shaft 1312. The arc surfaces of the clamping blocks 1314b are placed toward the outer circumference of the fixed shaft 1312. A clamping hole is provided on the splicing surface of the two clamping blocks 1314b, and an elastic member 1314c is provided between the two clamping blocks 1314b. The clamping hole may be one or more of a threaded hole, a through hole, and a countersunk hole. The elastic member may be a hollow elastic strip structure or a spring. The limiting structure 1314 may pass through the clamping holes of the clamping blocks at both ends and the elastic member 1314 in the middle of the clamping block through the locking member 1314d to tighten the two clamping blocks and thereby fix the fixed shaft. In one or more embodiments of the present disclosure, as Figure 5 As shown, the clamping hole of the proximal clamping block of the screw rod can be a through hole that penetrates the clamping block along the arrangement direction of the two clamping blocks, the clamping block of the distal clamping block of the screw rod can be a threaded hole with internal threads arranged along the arrangement direction of the two clamping blocks, the locking member can be a screw rod with external threads, and the elastic member can be a compression spring. The screw rod passes through the proximal clamping block and the compression spring, and is screwed into the threaded hole of the distal clamping block 31. When the screw rod rotates in one direction, the distance between the two clamping blocks will decrease until they clamp the fixed shaft 1312. It can be understood that a bearing is provided at the position on the fixed shaft 1312 that is clamped by the two clamping blocks, so as to ensure that the fixed shaft 1312 is axially limited without affecting the rotation of the fixed shaft.

[0039] Figure 6A stereoscopic diagram related to the movable shaft assembly 132 of the lens clamp according to an embodiment of the present disclosure is shown. In one or more embodiments of the present disclosure, the movable shaft assembly 132 also includes a motor mounting seat 1323 disposed on the clamp housing 134, and the second motor 1321 is fixed to the clamp housing 134 through the motor mounting seat 1323, and the output end of the second motor 1321 is connected to the movable shaft 1322 through a coupling, so that the second motor 1321 can drive the movable shaft 1322 to rotate in the second through hole.

[0040] Figure 7 A stereogram related to the movable shaft driving assembly 133 of the lens clamp according to an embodiment of the present disclosure is shown. In one or more embodiments of the present disclosure, the movable shaft driving assembly 133 also includes a guide rail 1333 fixed on the top of the clamp box 134 and a slider (not shown in the figure) slidably matched with the guide rail 1333, the guide rail 1333 is arranged parallel to the axial direction of the movable shaft 1322, and the slider 1334 is fixedly connected to the motor mounting seat 1323 of the movable shaft assembly 132, so that the slider can drive the second motor and the movable shaft to move along the guide rail 1333 through the motor mounting seat 1323. In one or more embodiments of the present disclosure, the screw rod 1331a is placed on the bearing mounting seat 1335 through bearings at both ends, the third motor 1332 is fixed to one of the bearing mounting seats 1335, and the screw rod 1331a is driven to rotate through a coupling, and the motor mounting seat 1323 is fixed to the nut 1331b of the screw rod pair. When the third motor 1332 drives the screw 1331a to rotate, the nut 1331b drives the motor mounting seat 1323 to perform lateral linear motion, thereby driving the movable shaft 1322 to clamp the lens to be processed or loosen the lens to be processed. In one or more embodiments of the present disclosure, the first motor and the second motor can be servo motors, which can drive the fixed shaft 1312 and the movable shaft 1322 to rotate through a coupling, so that the lens to be processed sandwiched between the fixed shaft 1312 and the movable shaft 1322 can be centered. Since the fixed shaft 1312 and the movable shaft 1322 are each driven by an independent servo motor, the motor can work at a higher speed (for example, not less than 3000 rad / min), and there is no complicated gear transmission mechanism between the motor and the corresponding shaft, which can meet the requirements of high-speed centering of the lens. In one or more embodiments of the present disclosure, the third motor 1332 can drive the screw 1331a to move with a constant torque, so that the lens fixture clamps the lens to be processed, meeting the requirements of high stability centering of the lens.

In one or more embodiments of the present disclosure, the liquid baffle can be a structure made of a hydrophobic material.
