[0025] See also Figure 1 and Figure 2 As shown, this embodiment discloses an optical lens 110 fine grinding machine, including a grinding device and a cooling device, and the grinding device and the cooling device are used to be installed on a workbench 101;

[0026] The cooling device includes a liquid storage box 102, a liquid collecting tank 103 and a collecting tank 104. The liquid storage box 102 is installed on both sides of the workbench 101. The liquid storage box 102 is used to store coolant. The liquid storage box 102 is provided with a spray pipe 105. The spray pipe 105 is used to spray coolant toward the grinding device. The liquid collecting tank 103 is installed on the workbench 101. Two inclined surfaces 106 are provided inside the liquid collecting tank 103. The two inclined surfaces 106 are arranged opposite to each other to form a liquid collecting channel 107. A filter screen 108 is provided on the liquid collecting channel 107.

[0027] The grinding device includes a grinding head assembly, a telescopic assembly and a loading assembly. The grinding head assembly is mounted on a workbench 101 and is used to grind an optical lens 110. The loading assembly and the telescopic assembly are both mounted on a liquid storage box 102. The optical lens is detachably mounted on the loading assembly. The telescopic assembly is connected to the loading assembly and is used to drive the loading assembly to reciprocate on the liquid storage box 102. The loading assembly is used to drive the optical lens 110 to contact the grinding head assembly.

[0028] The utility model mainly includes a grinding device and a cooling device, which are used to be installed on a workbench 101; in actual use, the staff first installs the optical lens 110 to be polished on the loading assembly, and then uses the driving device to drive the loading assembly to rotate, and then installs a plurality of grinding discs 113 on the grinding head assembly, and drives the loading assembly close to the grinding head assembly to grind the optical lens 110. At the same time, it is necessary to control the liquid storage box 102 to spray the coolant through the spray pipe 105 to spray the coolant onto the grinding head assembly, and cool the optical lens 110. After the liquid contacts the grinding head assembly, it splashes and the used coolant falls into the liquid collecting tank 103. Since both sides of the liquid collecting tank 103 are inclined surface 106 structures, the coolant is guided through the inclined surface 106 into the liquid collecting channel 107. The impurities generated during grinding are filtered by the filter 108, and the used coolant is collected by the collection box 104 through the liquid outlet 109. The advantage of this arrangement is that through the left and right movement of the telescopic assembly and the up and down movement of the loading assembly, not only the surface of the optical lens can be finely ground, but also the edge of the optical lens can be chamfered and edged.

[0029] In some embodiments, the grinding head assembly includes a motor 111 and a mounting seat 112. The motor 111 is installed under the workbench 101. The output shaft of the motor 111 passes through the workbench 101 and the liquid collecting tank 103 in sequence and is connected to the mounting seat 112. A plurality of grinding discs 113 are arranged in an array on the mounting seat 112.

[0030] During actual use, the staff starts the motor 111, and the motor 111 drives the mounting seat 112 to rotate, thereby causing the plurality of grinding discs 113 on the mounting seat 112 to rotate synchronously.

[0031] In some embodiments, the telescopic assembly drives the loading assembly to slide on the liquid storage box 102 through the moving structure.

[0032] In some embodiments, the mobile structure includes a base plate 114 and a slide plate 115 . The slide plate 115 is buckled on the base plate 114 and slidably matched with the base plate 114 . The slide plate 115 is connected to the telescopic assembly.

[0033] During actual use, the telescopic component extends or contracts to drive the slide plate 115 to slide on the bottom plate 114, thereby realizing the swing of the optical lens 110, so that the optical lens 110 can be polished at multiple angles.

[0034] In some embodiments, the loading assembly includes a moving frame 116, a mounting plate 117, a first motor 118 and a loading tray 119, the mounting plate 117 is fixed on the slide 115, the moving frame 116 is slidably set on the mounting plate 117, the first motor 118 is connected to the loading tray 119 through a transmission device, and a plurality of mounting grooves 120 are provided on the loading tray 119, and the interior of the mounting grooves 120 is used to install the optical lens 110; the transmission mechanism includes a second motor 122, a ball screw 123 and a screw nut 124, the second motor 122 is set on the mounting plate 117, and the screw nut 124 is fixedly installed on the moving frame 116, one end of the ball screw 123 is fixedly connected to the output shaft of the second motor 122, and the other end cooperates with the screw nut 124.

[0035] During actual use, the staff starts the second motor 122 to rotate. After the second motor 122 rotates, it drives the ball screw 123 to rotate. Since the screw nut 124 cooperates with the screw nut 124, the second motor 122 drives the movable frame 116 to slide on the mounting plate 117 after it rotates. The loading plate 119 is detachably provided with an optical lens 110. When in use, the second motor 122 drives the movable frame 116 to approach the polishing plate 113 in the forward direction, and then starts the first motor 118. The direction of the first motor 118 is opposite to that of the motor 111. After the first motor 118 rotates, it realizes the polishing of the optical lens 110 by rotating in the opposite direction to the motor 111.

[0036] The advantage of such a configuration is that the second motor 122 can adjust the height of the movable frame 116 to achieve the purpose of grinding lenses of different thicknesses.
