When the synchronous pulley 102 rotates, the clamping screw 101 The rod 101 rotates following the synchronous pulley 102, and the anti-rotation pin 121 limits the rotation of the clamping screw 101, which is then converted into horizontal movement of the clamping screw 101 (i.e., limiting the freedom of the rotation direction of the clamping screw 101); the output shaft of the mirror axis motor 113 is connected to the mirror axis pulley 114, and the mirror axis pulley 114 is provided with a mirror axis synchronous belt 115, and the mirror axis synchronous belt 115 is connected to the mirror axis synchronous pulley 112, and the mirror axis synchronous pulley 112 is connected to the mirror axis 110, and the mirror axis 110 is connected to the mirror axis bearing 111, and the mirror axis bearing 111 is connected to the lens suction cup 120, and the other side of the mirror axis 110 is connected to the mirror axis zero position disk 116, and the mirror axis zero position disk 116 is connected to the first micro switch 117.

[0028] The groove depth control unit 200 includes a base plate 204, on which a micro switch frame 205 and an iron stud 207 are provided, on which a second micro switch 206 is provided, on which the iron stud 207 is provided a groove depth linear motor 208, on which a groove depth control frame 209 is provided a groove depth rotating shaft 201 and a lens holder 203, and on which a first bearing 202 is provided.

[0029] The slotting control part 300 includes a first guide arm 301 and a second guide arm 302, and the first guide arm 301 and the second guide arm 302 can move closer to or away from each other. Specifically, the first guide arm 301 and the second guide arm 302 are respectively connected to motors (existing technology, not shown in the figure), and the motor controls the first guide arm 301 and the second guide arm 302 to move closer to or away from each other.

[0030] The grinding wheel part 400 is installed on the whole machine through a grinding wheel shaft mounting seat 404 . A grinding wheel shaft 403 is disposed on the grinding wheel shaft mounting seat 404 . A slotted wheel 401 , a chamfering wheel 402 and a grinding wheel pulley 405 are disposed on the grinding wheel shaft 403 .

[0031] The longitudinal and transverse moving part 500 includes a Z-axis motor 501, and the Z-axis motor 501 is connected to a Z-axis screw rod 502, and the Z-axis screw rod 502 is connected to a Z-axis spline 503; a micro switch mounting block 504 is provided on the Z-axis screw rod 502, and a fourth micro switch 505 is provided on the micro switch mounting block 504; a roller mounting seat 506 is provided on the Z-axis spline 503, and a flange bearing 507 and a roller 508 are provided on the roller mounting seat 506; a guide shaft 509 is installed on the machine head 100 to contact the roller 508.

[0032] It should be noted that when the lens is clamped: after the lens suction cup is placed in the specified position, the clamping motor 106 is driven by the program, thereby driving the clamping pulley 107 to rotate, and then driving the synchronous pulley 102 to rotate through the clamping shaft synchronous belt 108, so that the clamping screw 101 rotates, and under the constraint of the anti-rotation groove 105, the clamping suction cup 109 is driven to move horizontally to the right until the clamping suction cup 109 touches the lens 600 and stops; during the operation: the mirror shaft motor 113 is driven by the program, thereby driving the mirror shaft pulley 114 to rotate, and then driving the mirror shaft synchronous pulley 112 through the mirror shaft synchronous belt 115, thereby driving the mirror shaft 110 to rotate, and then driving the lens 600 to rotate, and then driving the clamping screw 101 to rotate in the first limit bearing 103 and the second limit bearing 104; at the same time, the mirror shaft 110 drives the mirror shaft zero position disk 116 to rotate, thereby controlling the closing of the first micro switch 117, so as to achieve the purpose of resetting and recording the number of processing circles;

[0033] After the lens is clamped: the program drives the motor to drive the first guide arm 301 and the second guide arm 302 to move away from each other, that is, the guide arms are opened at the same time to facilitate the lens 600 to fall into place; at the same time, since the first guide arm 301 and the second guide arm 302 are individually controlled by the motor, various movement modes can be realized, such as the first guide arm 301 opening alone, the second guide arm 302 opening alone, the first guide arm 301 and the second guide arm 302 opening at the same time, and the first guide arm 301 and the second guide arm 302 closing toward each other, thereby controlling the slotting position of the lens.

When the lens 600 contacts the grinding wheel part 400, the roller 508 is separated from the guide shaft 509. After the lens processing is completed, the Z-axis motor 501 rotates counterclockwise, the Z-axis spline 503 moves downward, and then the roller 508 contacts the guide shaft 509 and drives the guide shaft 509 to move upward, thereby driving the head 100 to move upward until the fourth micro switch 505 contacts the Z-axis motor 501 and stops when it is closed; the guide shaft 509 can be automatically reset under the action of gravity of the head 100.

[0035] The groove depth linear motor 208 is driven by the program, which in turn drives the groove depth control frame 209 to rise and fall, and then the lens bracket 203 is raised and lowered, thereby controlling the contact degree between the lens 600 and the groove wheel 401, that is, controlling the groove depth; the closed position of the second micro switch 206 is the zero position of the groove depth control frame 209.

[0036] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. 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.
