Description
Technical Field
[0001] This utility model relates to the field of lens processing technology, specifically to an upper pendulum grinding structure for lens processing. Background Technology
[0002] With the rapid development of optoelectronic technology, medical imaging, aerospace and other fields, the demand for high-performance optical lenses is constantly increasing. For example, medical imaging equipment, optical communication systems, and optical display equipment all require high-quality optical lenses. Consumer electronics products such as smartphones, tablets, and digital cameras use a large number of optical lenses and optical imaging systems, driving a large demand for optical lenses. The continuous increase in the global population has driven the demand for everyday optical products such as eyeglasses and telescopes. With the improvement of living standards, people's demand for high-definition images and visual experiences is constantly increasing. For example, high-definition televisions and AR / VR devices all require advanced optical lenses.
[0003] The main technical problems of the upper pendulum grinding machine in the rough grinding process of optical lenses are as follows: the magnitude of the grinding force applied to the lens directly affects the grinding efficiency and surface quality. It is necessary to precisely control the magnitude and uniformity of this force. Excessive grinding force may damage the lens surface, while insufficient force will not achieve the desired grinding effect. Existing upper pendulum grinding machines mostly use cylinders or telescopic motors as power sources when driving the grinding structure up and down, resulting in poor force control precision. Therefore, it is urgent to propose an upper pendulum grinding structure for lens processing. Utility Model Content
[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.
[0005] Therefore, the purpose of this utility model is to provide an upper pendulum grinding structure for lens processing. A servo motor drives the lead screw to rotate in the connecting groove, which in turn drives the threaded seat to slide step by step along the guide groove, thereby changing the height position of the bracket and driving the grinding component to move step by step downward, which can precisely control the magnitude and uniformity of the grinding force.
[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:
[0007] An upward grinding structure for lens processing, comprising:
[0008] The working chamber is a working box with a mounting bracket connected to its outer side;
[0009] The stepper assembly, connected to the mounting bracket, provides power to drive the grinding motor to move up and down along the inside of the work box;
[0010] The grinding component is connected to the stepper assembly and moves synchronously with the stepper assembly to assist in grinding the lens placed in the work box.
[0011] The base component is connected inside the work box, which helps to fix the lens while driving the lens to rotate.
[0012] As a preferred embodiment of the lens processing upper pendulum grinding structure described in this utility model, the mounting frame has a connecting groove inside, and a guide groove communicating with the connecting groove is provided on the outside of the mounting frame.
[0013] As a preferred embodiment of the lens processing upper pendulum grinding structure described in this utility model, a dust collector is connected to the outside of the work box, a dust collection pipe is connected to the dust collection port of the dust collector, and the other end of the dust collection pipe is connected to the work box.
[0014] As a preferred embodiment of the lens processing upper pendulum grinding structure described in this utility model, the stepper assembly includes a servo motor connected to the top of the mounting frame, the output end of the servo motor is connected to a lead screw, the lead screw extends into the connecting groove, a threaded seat is screwed onto the lead screw, a guide seat that slides with the guide groove is integrally formed on the outside of the threaded seat, and a bracket is connected to the outside of the guide seat.
[0015] As a preferred embodiment of the lens processing upper pendulum grinding structure described in this utility model, the grinding component includes a grinding motor connected to the top of the bracket, and the output end of the grinding motor is connected to the grinding disc.
[0016] As a preferred embodiment of the lens processing upper pendulum grinding structure described in this utility model, the base component includes a rotating seat connected to the bottom of the inner side of the work box, a connecting frame is provided on the top of the rotating seat, a negative pressure pump is connected to the bottom of the connecting frame, a connecting pipe is provided at the output end of the negative pressure pump, the other end of the connecting pipe is connected to a negative pressure suction cup, and the negative pressure suction cup is connected to the top of the connecting frame.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] The servo motor drives the lead screw to rotate within the connecting groove, which in turn drives the threaded seat to slide stepwise along the guide groove, changing the height of the bracket and causing the grinding component to move stepwise downwards. This allows for precise control of the grinding force and its uniformity. Simultaneously, a negative pressure pump provides negative pressure, which, in conjunction with a negative pressure suction cup, adsorbs and fixes the lens onto the connecting frame. This avoids the impact of clamps on the grinding range when using them for holding the lens, and the rotating seat can also change the position of the lens for grinding in different locations.

[0028] This utility model provides an upper pendulum grinding structure for lens processing. Please refer to [link / reference]. Figure 1-3 It includes a work box 100, a stepping assembly 200, a grinding component 300, and a base component 400;
[0029] Please continue reading. Figure 1-3 The working chamber 100 has a mounting bracket 110 threadedly connected to its outer side via a positioning bolt. The mounting bracket 110 has a connecting groove 111 inside and a guide groove 112 connected to the connecting groove 111 on its outer side. A dust collector 120 is screwed onto the outer side of the working chamber 100. The dust collection port of the dust collector 120 is connected to a dust collection pipe 121. The other end of the dust collection pipe 121 is connected to the working chamber 100. The dust collector 120 and the dust collection pipe 121 cooperate to help absorb the waste chips generated during the grinding process.
[0030] Please continue reading. Figure 1-3 The stepper assembly 200 is connected to the mounting bracket 110 and provides power to drive the grinding motor 310 to move up and down within the work box 100.
[0031] The stepper assembly 200 includes a servo motor 210 threadedly connected to the top of the mounting bracket 110. The output end of the servo motor 210 is connected to a lead screw 211, which extends into the connecting groove 111. A threaded seat 220 is screwed onto the lead screw 211. A guide seat 221 that slides with the guide groove 112 is integrally formed on the outside of the threaded seat 220 (the rotation direction of the threaded seat is restricted by the guide groove and the guide seat, so that when the lead screw rotates, the threaded seat moves along the outside of the lead screw, thereby changing the position of the bracket, as shown in the lead screw feed action). A bracket 230 is connected to the outside of the guide seat 221.
[0032] action:
[0033] The servo motor 210 drives the lead screw 211 to rotate within the connecting groove 111, thereby driving the threaded seat 220 to slide step by step along the guide groove 112, causing the height position of the bracket 230 to change.
[0034] Please continue reading. Figure 1-2 The polishing component 300 is connected to the stepping component 200 and moves synchronously with the stepping component 200 to assist in polishing the lens placed in the work box 100.
[0035] The polishing component 300 includes a polishing motor 310 threadedly connected to the top of the bracket 230. The output end of the polishing motor 310 is connected to the polishing disc 320 via a connecting bolt. The polishing motor 310 drives the polishing disc 320 to rotate, thereby assisting in the polishing of the lens.
[0036] Please continue reading. Figure 3The base component 400 is connected inside the work box 100, which helps to fix the lens while driving the lens to rotate;
[0037] The base component 400 includes a rotating seat 410 connected to the bottom of the inner side of the work box 100. A connecting frame 411 is provided on the top of the rotating seat 410. A negative pressure pump 420 is connected to the bottom of the connecting frame 411. A connecting pipe 421 is provided at the output end of the negative pressure pump 420. The other end of the connecting pipe 421 is connected to a negative pressure suction cup 422. The negative pressure suction cup 422 is connected to the top of the connecting frame 411.
[0038] action:
[0039] The negative pressure pump 420 provides negative pressure, which, in conjunction with the negative pressure suction cup 422, adsorbs and fixes the lens onto the connecting frame 411. This avoids the clamping fixture affecting the grinding range when the lens is held by a clamp, and the rotating seat 410 can drive the lens to change position for grinding in different positions.
[0040] Working principle: When in use, the servo motor 210 drives the lead screw 211 to rotate within the connecting groove 111, which in turn drives the threaded seat 220 to slide stepwise along the guide groove 112, causing the height of the bracket 230 to change, and driving the grinding component 300 to move stepwise downward. This allows for precise control of the magnitude and uniformity of the grinding force. At the same time, the negative pressure pump 420 provides negative pressure, which, in conjunction with the negative pressure suction cup 422, adsorbs and fixes the lens onto the connecting frame 411. This avoids the impact of clamps on the grinding range when using clamps, and the rotating seat 410 can change the position of the lens for grinding at different locations.
[0041] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
