Description

Technical Field

[0001] This utility model relates to the field of optical lens edging equipment technology, and in particular to an optical lens edging machine based on cross laser centering. Background Technology

[0002] The basic processing technology of optical lenses generally includes milling the blank, fine grinding and polishing, centering and edge grinding, cleaning and drying, coating and ink application, etc. Among them, the lens after fine grinding and polishing is generally not centered and has a center deviation. In order to ensure that the imaging quality after assembly is not affected, the optical axis needs to be aligned with the mechanical axis and the oddly shaped edges need to be ground off to ensure the accuracy of assembly and fixing.

[0003] Currently, centering grinding equipment is commonly used to perform centering and edge grinding operations on finely ground optical lenses. Traditional centering equipment typically involves manually holding the lens to be centered and edged between two rotating spindles. After the operator observes that the center position of the optical lens coincides with the auxiliary crosshair, it is fixed by a clamping mechanism. Then, the rotating spindle drives the optical lens to rotate, which in turn drives the grinding parts to perform the edge grinding operation on the optical lens.

[0004] However, the manual hand-held lens alignment method has the problem that the lens is prone to positional displacement when it is clamped, which leads to incorrect centering data, affects the quality of the finished product, and results in poor work performance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an optical lens edging machine based on cross-laser centering, which solves the problem that manual hand-held lens handling and auxiliary light positioning clamping can easily lead to errors in centering data, resulting in poor work performance.

[0006] According to an embodiment of this utility model, an optical lens edging machine based on cross-laser centering includes a base, a laser emitter, a grinding chamber, a horizontal clamping member, a vertical clamping member, and a cross module. The grinding chamber is fixedly installed on the other side of the top of the base and is used to correspond to the laser emitter. The grinding chamber is provided with grinding components. The horizontal clamping member is installed on both sides of the grinding chamber and is used to clamp the lens after alignment with the auxiliary light. One side of the horizontal clamping member is connected to the laser emitter. The vertical clamping member is located on one side of the base and is vertically distributed with the laser emitter. The vertical clamping member extends into the grinding chamber and is used to clamp the lens to be processed. The cross module is installed at the bottom of the vertical clamping member and is used to make the vertical clamping member drive the lens to align with the auxiliary light.

[0007] In the above embodiment, a laser emitter and a grinding chamber are arranged opposite each other on the base, and a horizontal clamping member is set in the grinding chamber to hold the lens to be ground. Specifically, the lens to be ground is placed on one side of the vertical clamping member extending into the grinding chamber, and then the position of the vertical clamping member is controlled by a cross module to adjust the alignment of the lens held on the vertical clamping member with the auxiliary light of the laser emitter. Then, the horizontal clamping member holds the lens after it is aligned with the auxiliary light, and the vertical clamping member releases the lens and moves it away from the grinding chamber, leaving working space for the lens to be ground, thus completing the operation without the need for manual handling of the lens, ensuring the accuracy of alignment.

[0008] In some embodiments, the grinding chamber is hollow, and the grinding element is disposed on the inner top of the grinding chamber.

[0009] In some embodiments, the grinding chamber has sliding holes on both sides that are adapted to the horizontal clamping member. The horizontal clamping member includes a pair of clamping cylinders respectively installed in the two sliding holes and an adjusting seat fixedly installed at the bottom of the grinding chamber. A first screw is rotatably provided on the adjusting seat. The external thread of the first screw is connected to two sliders respectively fixedly connected to the bottom of the two clamping cylinders. A first motor for driving the first screw is provided on one side of the adjusting seat.

[0010] In some embodiments, the two clamping cylinders are coaxially arranged, with one clamping cylinder having its end opposite to the grinding chamber slidably fitted onto the outside of the laser emitter's end, and the other clamping cylinder having a laser receiver connected to its side opposite to the grinding chamber.

[0011] In some embodiments, the vertical clamping member includes a pair of clamping arms that are vertically distributed and extend into the interior of the grinding chamber, and a pair of threaded sleeves fixedly installed on one end of the clamping arms opposite to the grinding chamber. A support sleeve is fitted on one side of the two threaded sleeves. A second screw is rotatably disposed inside the support sleeve and threadedly connected to the interior of the two threaded sleeves. A second motor for driving the second screw is installed on the top of the support sleeve. The side of the support sleeve opposite to the clamping arms is connected to the cross module.

[0012] In some embodiments, the two clamping arms extend into the grinding chamber and are located between the two clamping cylinders, and the ends of the two clamping arms on the proximal side are provided with clamping pads and fixing pins for installing the clamping pads.

[0013] In some embodiments, the cross module includes a translation module connected to the bottom of the base at one end and a lifting module vertically mounted on the top of the translation module. The lifting module is connected to the side of the support sleeve opposite to the clamping arm.

[0014] Compared with the prior art, this utility model has the following beneficial effects: by adopting a vertical clamping component that can hold the lens in the vertical direction to replace the method of manually holding the lens to align with the auxiliary light, it solves the technical problem that the positioning and clamping of the lens by manually holding it and the auxiliary light in the existing edging machine device is prone to errors in the centering data, resulting in poor work effect, thereby achieving the technical effect of improving the lens alignment accuracy.

[0023] In an exemplary implementation, such as Figures 1-5 As shown, this embodiment provides an optical lens edging machine based on cross laser centering, including a base 100, a laser emitter 200, a grinding chamber 300, a horizontal clamping member 400, a vertical clamping member 500, and a cross module 600. The grinding chamber 300 is fixedly installed on the other side of the top of the base 100 and is used to correspond to the laser emitter 200. A grinding component 310 is provided inside the grinding chamber 300. The horizontal clamping member 400 is installed on both sides of the grinding chamber 300 and is used to clamp the lens after it has been aligned with the auxiliary light. One side of the horizontal clamping member 400 is connected to the laser emitter 200. The vertical clamping member 500 is located on one side of the base 100 and is vertically distributed with the laser emitter 200. The vertical clamping member 500 extends into the grinding chamber 300 and is used to clamp the lens to be processed. The cross module 600 is installed at the bottom of the vertical clamping member 500 and is used to make the vertical clamping member 500 drive the lens to align with the auxiliary light.

[0024] In this embodiment, a laser emitter 200 and a polishing chamber 300 are arranged opposite each other on the base 100. A horizontal clamping member 400 is provided in the polishing chamber 300 to hold the lens to be polished. Specifically, the lens to be polished is placed on one side of the vertical clamping member 500 extending into the polishing chamber 300. Then, the position of the vertical clamping member 500 is controlled by the cross module 600 to adjust the alignment of the lens held on the vertical clamping member 500 with the auxiliary light of the laser emitter 200. The horizontal clamping member 400 then holds the lens after it is aligned with the auxiliary light. The vertical clamping member 500 releases the lens and moves it away from the polishing chamber 300, leaving working space for the polishing member 310. This completes the operation without the need for manual handling of the lens, ensuring the accuracy of alignment.

[0025] In one embodiment, please refer to Figure 1 The grinding chamber 300 is hollow, and the grinding component 310 is located on the inner top of the grinding chamber 300.

[0026] In this embodiment, the bottom of the grinding chamber 300 is inclined, which is used to discharge grinding coolant during actual operation. The opening of the grinding chamber 300 is provided with a groove, which can be used to install a protective baffle.

[0027] In one embodiment, please refer to Figures 1-5 The grinding chamber 300 has sliding holes 320 on both sides that are adapted to the horizontal clamping member 400. The horizontal clamping member 400 includes a pair of clamping cylinders 410 respectively installed in the two sliding holes 320 and an adjusting seat 420 fixedly installed at the bottom of the grinding chamber 300. A first screw 430 is rotatably installed on the adjusting seat 420. The external thread of the first screw 430 is connected to two sliders 440 respectively fixedly connected to the bottom of the two clamping cylinders 410. A first motor 450 for driving the first screw 430 is provided on one side of the adjusting seat 420.

[0028] In this embodiment, the lens after the auxiliary light is aligned can be clamped by the clamping cylinder 410. Specifically, the output shaft of the first motor 450 is fixedly connected to one end of the first screw 430, driving the first motor 450 to drive the first screw 430 to rotate. The rotation of the first screw 430 causes the two sliders 440 threaded to it to move away from each other or move closer to each other, thereby controlling the clamping and releasing actions of the two clamping cylinders 410.

[0029] The two clamping cylinders 410 are coaxially arranged. One clamping cylinder 410 is slidably sleeved on the outside of the end of the laser emitter 200 at the end opposite to the grinding chamber 300, and the other clamping cylinder 410 is connected to the laser receiver 210 on the side opposite to the grinding chamber 300.

[0030] Specifically, the laser emitter 200 emits an auxiliary light beam from its end and transmits it to the clamped lens through a nearby clamping cylinder 410. The auxiliary light beam passes through the lens and enters another clamping cylinder 410 until it enters the laser receiver 210. The alignment status of the lens is then displayed through an external display mechanism.

[0031] In one embodiment, please refer to Figures 1-5 The vertical clamping member 500 includes a pair of clamping arms 510 that are vertically distributed and extend into the interior of the grinding chamber 300, and a pair of threaded sleeves 520 that are fixedly installed on one end of the clamping arms 510 opposite to the end of the grinding chamber 300. A support sleeve 530 is sleeved on one side of the two threaded sleeves 520. A second screw 540 that is rotatably connected to the inside of the two threaded sleeves 520 is rotatably disposed in the support sleeve 530. A second motor 550 for driving the second screw 540 is installed on the top of the support sleeve 530. The side of the support sleeve 530 opposite to the clamping arms 510 is connected to the cross module 600.

[0032] In this embodiment, the lens to be aligned with the auxiliary light is held by the clamping arm 510 and adjusted by the cross module 600. Specifically, the lens to be processed is placed between the two clamping arms 510. The output shaft of the second motor 550 is fixedly connected to one end of the second screw 540. At this time, the second motor 550 is started to drive the second screw 540 to rotate, so that the two screw sleeves 520 located outside the second screw 540 can come closer to each other to hold the lens. Then, under the control of the cross module 600, the clamping arm 510 drives the lens to align with the auxiliary light.

[0033] The two clamping arms 510 extend into the grinding chamber 300 and are located between the two clamping cylinders 410. The ends of the two clamping arms 510 on the adjacent sides are provided with clamping pads 511 and fixing pins 512 for installing the clamping pads 511.

[0034] In this embodiment, the clamping pad 511 can improve the stability of the clamping arm 510 in clamping the lens.

[0035] In one embodiment, please refer to Figure 1 and Figure 2 The cross module 600 includes a translation module 610 connected to the bottom of the base 100 at one end and a lifting module 620 vertically installed on the top of the translation module 610. The lifting module 620 is connected to the side of the support sleeve 530 opposite to the clamping arm 510.

[0036] Finally, this application does not provide specific descriptions of some existing structures, such as the display mechanism aligned with the auxiliary light, the control circuits between various electronic components, and the control console. These are adapted and modified to meet the needs of actual operation and will not be elaborated upon further.

[0037] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail as follows: In use, a laser emitter 200 and a grinding chamber 300 are arranged opposite each other on the base 100, and a horizontal clamping member 400 is set in the grinding chamber 300 to hold the lens to be ground. Specifically, the lens to be processed is placed between two clamping arms 510. The output shaft of the second motor 550 is fixedly connected to one end of the second screw 540. At this time, the second motor 550 is started to drive the second screw 540 to rotate, so that the two screw sleeves 520 located outside the second screw 540 can approach each other to clamp the lens. Then, under the control of the translation module 610 and the lifting module 620, the clamping arm 510 drives the lens to align with the auxiliary light. After alignment, it waits for the clamping cylinder 410 to clamp it.

[0038] Furthermore, the specific operation of the clamping cylinder 410 is as follows: the output shaft of the first motor 450 is fixedly connected to one end of the first screw 430, driving the first motor 450 to rotate the first screw 430. The rotation of the first screw 430 causes the two sliders 440 threaded to it to move closer to each other, thereby controlling the two clamping cylinders 410 to clamp the lens. Meanwhile, the clamping arm 510 releases the lens and moves away from the grinding chamber 300, leaving working space for the grinding workpiece 310, thus completing the operation without the need for manual handling of the lens, ensuring the accuracy of alignment.

[0039] In summary, this utility model solves the technical problem in existing edging machines where manual holding of the lens and positioning of the lens with the auxiliary light source can easily lead to errors in the centering data, resulting in poor work performance. This is achieved by using a vertical clamping component 500 that can hold the lens vertically to replace the manual holding of the lens with the auxiliary light source for alignment.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
