Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of eyeglass lens scanners, in particular to a centering device for eyeglass lens scanners. Background Art
[0002] With the rapid development of lens technology in recent years, the current market demand for eyeglass processing has gradually increased. However, the process of processing eyeglasses into wearable glasses is relatively complicated, among which centering and clamping of processed eyeglasses is a very critical process. At present, eyeglass processors generally center and clamp the eyeglasses on the scanner after scanning the outline of the processed lens graphics, or choose to clamp them on a separate center locator, and the whole process is done manually, which brings a problem, that is, the pressure when clamping the eyeglasses is inconsistent and uncontrollable. For the eyeglass lens clamping process, if the pressure during clamping is too high, it will be too labor-intensive in the long run; if the pressure is too low, the clamping may not be tight, causing the eyeglasses to fall off, seriously affecting the accuracy of the eyeglass lens processing.
[0003] In addition, the processor faces another problem, that is, the colors of glasses with different functions are different, for example, blue lenses can relieve visual fatigue, brown lenses can absorb ultraviolet rays and enhance color contrast, etc. When the glasses are clamped, they will filter or absorb part of the irradiated light, so that the optical center point marked on them cannot be clearly seen. Therefore, it is difficult for the processor to determine the center, which delays the working time and reduces efficiency. Utility Model Content

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0018] like Figure 1-6 As shown, a centering device for a lens scanner includes a centering system 100, an optical system 200, an imaging system 300, a main control board 400 and a display touch screen 500; the centering system 100 is fixed on the lower side of the imaging system 300, the optical system 200 is fixed on the lower side of the centering system 100, and the centering system 100, the optical system 200, the imaging system 300 and the display touch screen 500 are electrically connected to the main control board 400 respectively.
[0019] The centering system 100 includes a base 112, on which a motor 101 is provided, the output end of the motor 101 is connected to the rotating shaft 102, the rotating shaft 102 is sleeved with a flange bearing 103, and the flange bearing 103 is connected to a flange bearing seat 111; the rotating shaft 102 is sleeved with a clamping arm 104 and a main spring 110, a cam 106 is fixed to the top of the rotating shaft 102, the clamping arm 104 is provided with a cam column 105, a strain gauge 107, a suction cup mounting seat 108 and a center positioning column 113, and one end of the cam column 105 is sleeved with a pressure adjustment spring 109; the center positioning column 113 is connected to a mounting plate 116, and a control switch 114 and a center positioning sleeve 115 are provided on the mounting plate 116.
[0020] It should be noted that when the centering system is working, the motor 101, the strain gauge 107 and the control switch 114 are connected to the main control board 400;
[0021] When in the automatic centering mode: the center positioning column 113 and the control switch 114 are in contact, and the clamping arm 104 is gently pushed to separate the center positioning column 113 from the control switch 114. The control switch 114 transmits a signal to the main control board 400, and the main control board 400 transmits a signal to the motor 101, which drives the motor 101 to drive the shaft 102 to rotate clockwise, and the cam 106 rotates synchronously with the shaft 102; when the cam 106 contacts the cam column 105, the cam column 105 rotates with the cam 106 under the action of the force, and then the clamping arm 104 rotates. When the center positioning column 113 moves to contact the center positioning sleeve 115, the clamping arm 104 stops rotating under the restriction of the center positioning sleeve 115, and the cam 106 continues to rotate, thereby squeezing the cam column 105 to make it move downward;
[0022] The main spring 110 and the pressure adjustment spring 109 are compressed, and the cam column 105 contacts and squeezes the strain gauge 107, that is, the deformation degree of the strain gauge 107 reflects the compression degree of the pressure adjustment spring 109, and further reflects the magnitude of the pressure. The downward pressure threshold is set by displaying the touch screen 500, that is, when the pressure value converted from the deformation of the strain gauge 107 reaches the set threshold, the strain gauge pressure threshold is obtained by calibration, and the strain gauge 107 transmits a signal to the main control board 400, and the main control board 400 controls the motor 101 to stop and maintain pressure. This process achieves the purpose of controllable pressure. It should be further explained that different pressure values can be set for lenses of different materials and thicknesses to achieve the purpose of firmly clamping the lenses;
[0023] After a period of time, the motor 101 starts to rotate in the opposite direction. At this time, as the cam 106 rotates in the opposite direction, the force of the cam 106 on the cam column 105 is gradually cancelled, and the cam column 105 is reset under the action of the pressure adjustment spring 109, and then the strain gauge 107 is reset. At the same time, under the action of the main spring 110, the clamping arm 104 moves upward until the center positioning column 113 is separated from the center positioning sleeve 115. Then, under the action of the motor 101, the cam 106 is reset, and its side plane contacts and pushes the cam column 105, thereby driving the clamping arm 104 to reset until the center positioning column 113 contacts the control switch 114 to stop, and the automatic centering process ends.
[0024] When in manual centering mode: at this time, the control disconnects the motor 101, strain gauge 107 and control switch 114 from the main control board 400. At this time, the entire centering process relies on manually pushing the rocker arm 104 to reach the specified position. As mentioned above, the cam column 105 contacts and presses down with the center positioning sleeve 115, and then the main spring 110 pushes and clamps the rotating arm 104 to reset. The principle is the same as the above-mentioned automatic centering mode and will not be repeated here.
[0025] The imaging system 300 includes a lens 301, a lens 302 and an image sensor module 303. The lens 302 is disposed on the upper side of the lens 301, and the image sensor module 303 is disposed on the upper side of the lens 302. The image sensor module 303 is connected to the main control board 400. The optical system 200 is a light source with adjustable brightness, which is controlled by the main control board 400.
[0026] It should be noted that when the eyeglass lens 600 is placed in the center area of the device, the image sensing module 303 collects the image of the lens to be tested through the lens 301 and the lens 302, and transmits it to the main control board 400. During this process, when the image received by the main control board 400 does not meet the requirements, the main control board 400 controls the optical system 200 to adjust the brightness of the light source to ensure that the image sensing module 303 collects a suitable image and transmits it to the main control board 400. After being processed by the main control board 400, the image is transmitted to the display touch screen 500 and displayed, and the image on the display touch screen 500 is observed.

Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
