Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Example 1

[0030] Reference Figure 1-3, which is the first embodiment of the utility model, provides a lens cutting device for optical lens production, including a base 1 and an operating table 2 fixedly arranged at the middle end of the base 1, a plurality of groups of nozzles 3 are evenly arranged at one end of the inner walls of the front and rear ends of the operating table 2 close to each other, a cutting table 4 is arranged at the middle end of the operating table 2, a first motor 5 is arranged at the upper end of the base 1, an electric telescopic rod 6 is connected to the output end of the first motor 5, a cutting component 7 is arranged at the extended end of the electric telescopic rod 6, a fixing component 8 is arranged at the lower end of the cutting component 7, a cleaning component 9 is arranged on one side outer wall of the base 1, and a collecting component 13 is arranged at the lower end of the operating table 2;

[0031] The cutting assembly 7 includes a placement box 71 arranged at the extended end of the electric telescopic rod 6, the inner wall of the upper end of the placement box 71 is connected to the second motor 72, and a bidirectional ball screw 73 is arranged at the output end of the second motor 72. The outer wall of the bidirectional ball screw 73 is sleeved with two symmetrical groups of first ball screw sleeves 74, and two groups of first adjusting rods 75 are symmetrically arranged at the front and rear ends of the first ball screw sleeve 74. A connecting block 76 is arranged at the end of the first adjusting rod 75 away from the first ball screw sleeve 74, and a connecting rod 77 is arranged at the lower end of the connecting block 76. A fixing rod 78 is arranged at the lower end of the connecting rod 77, and a cutter 79 is arranged at the lower end of the fixing rod 78.

[0032] The two ends of the first adjusting rod 75 are hinged to the first ball screw sleeve 74 and the connecting block 76 respectively. The cutting assembly 7 also includes two groups of fixed rods 78 symmetrically arranged at the lower end of the placement box 71. The connecting rod 77 is movably sleeved on the outer wall of the fixed rod 78, and the fixed rod 78 and the connecting rod 77 are slidably connected.

[0033] The fixing assembly 8 includes a sleeve 81 arranged at the lower end of the placement box 71, a spring 82 is inserted into the inner wall of the sleeve 81, the upper end of the spring 82 is fixedly connected to the inner wall of the upper end of the sleeve 81, a slide rod 83 is fixedly arranged at the lower end of the spring 82, two symmetrical groups of slide blocks are arranged at both ends of the outer wall of the slide rod 83, and a slide groove matching the slide block is opened on the inner wall of the sleeve 81.

[0034] The fixing assembly 8 further includes a rubber vacuum suction cup 84 disposed at the lower end of the sliding rod 83 .

[0035] The lens to be cut is placed on the upper end of the cutting table 4, and then according to the required cutting size, the second motor 72 is started to rotate to drive the bidirectional ball screw 73 to rotate. The bidirectional ball screw 73 rotates to drive the two groups of first ball screw sleeves 74 to move closer to or away from each other. When the two groups of first ball screw sleeves 74 move away from each other, the first adjusting rod 75 is hinged to the first ball screw sleeve 74 and the connecting block 76 respectively, thereby driving the two groups of connecting blocks 76 to move closer to each other, and the connecting block 76 drives the connecting rod 77 to slide along the fixed rod 78, and the two groups of connecting rods 77 move closer to each other, thereby reducing the distance between the cutters 79, that is, smaller-sized lenses can be cut. Then, the electric telescopic rod 6 is started to drive the cutter 79 to move downward. When it touches the lens, the first motor 5 is started to rotate. The rotation of the first motor 5 drives the cutter 79 to rotate, thereby completing the cutting of the lens. When the telescopic rod 6 drives the cutter 79 to move downward, the rubber vacuum suction cup 84 contacts the lens, and then drives the rubber vacuum suction cup 84 to squeeze the lens downward. The spring 82 is gradually compressed by the upward force, and the cutting slide rod 83 slides upward along the sleeve 81. The elastic force of the spring 82 can buffer the pressure acting on the lens to avoid the lens from being broken due to greater pressure. When the cutter 79 contacts the lens, the electric telescopic rod 6 stops moving and fixes the center of the upper end of the lens with the rubber vacuum suction cup 84 under the reverse force of the spring 82, which can prevent the lens from moving during the cutting process and affecting the cutting accuracy. After cutting is completed, the electric telescopic rod 6 can be retracted. Under the suction action of the rubber vacuum suction cup 84, the cut lens is adsorbed by the rubber vacuum suction cup 84, so that the cut lens leaves the cutting table 4, which is convenient for subsequent cleaning of the cutting table.

[0036] Example 2

[0037] Reference Figure 4-6 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that: the cleaning assembly 9 includes a ball screw 91 rotatably arranged on one side of the outer wall of the base 1, a third motor 92 is arranged on the upper end of the ball screw 91, a second ball screw sleeve 93 is sleeved on the outer wall of the ball screw 91, a second adjusting rod 94 is hingedly arranged on one side of the second ball screw sleeve 93, a first slide groove 10 matching with the second adjusting rod 94 is opened on the outer wall of the base 1, a sliding plate 95 is hingedly arranged at the lower end of the second adjusting rod 94, a cleaning brush 96 is fixedly arranged at the lower end of the sliding plate 95, a second slide groove 11 matching with the sliding plate 95 is opened on the inner walls at the front and rear ends of the base 1, and the sliding plate 95 is slidably connected with the second slide groove 11;

[0038] A plurality of through holes 12 are evenly formed through the upper end of the operating table 2;

[0039] The collecting assembly 13 includes a collecting frame 131 arranged at the lower end of the operating table 2, a collecting opening 132 is opened at the upper end of the collecting frame 131, and a discharging opening 133 is opened at the lower end of the collecting frame 131. The collecting frame 131 is arranged in a funnel shape that is wide at the top and narrow at the bottom. A slope 134 is arranged at the upper end of the collecting frame 131, and the width of the collecting opening 132 is greater than the width of the operating table 2.

[0040] A collecting box 14 is movably connected to the upper side of the bottom end of the base 1 , and the collecting box 14 is located at the lower end of the discharge port 133 .

[0041] After the lens is sucked away from the cutting table 4 by the rubber vacuum suction cup 84, since dust and lens debris are often easily diffused during the cutting process of the optical lens, water is passed through the nozzle 3 to clean the cutting table 4 and the operating table 2, and then the third motor 92 is started to rotate to drive the ball screw 91 to rotate, and the rotation of the ball screw 91 drives the second ball screw sleeve 93 to move downward. Since the upper and lower ends of the second adjusting rod 94 are respectively hinged to the second ball screw sleeve 93 and the sliding plate 95, and the sliding plate 95 is slidably connected to the second slide groove 11, during the downward movement of the second ball screw sleeve 93, the second adjusting rod 94 drives the sliding plate 95 slides along the second slide groove 11, and the dust and debris on the upper ends of the cutting table 4 and the operating table 2 are cleaned by the cleaning brush 96. The waste water will fall into the collecting frame 131 through the through hole 12. The larger debris and impurities that cannot pass through the through hole 12 are gathered to the front end of the operating table 2 under the push of the cleaning brush 96, and then fall to the upper end of the gathering port 132 and enter the collecting frame 131. Under the guidance of the inclined surface 134, the debris and the waste water for cleaning the dust fall into the collecting box 14, and the collecting box 14 is pulled out to clean the debris and waste water therein. The above operation can quickly clean the debris and dust generated during the cutting process to avoid affecting the next cutting.

[0042] The remaining structures are the same as those of Example 1.
