Description

[0001] technical field.

[0002] The utility model relates to the technical field of optical lens processing, in particular to a novel driving mechanism for optical equipment.

[0003] Background technology.

[0004] Optical lenses are one of the important components in optical equipment. In the production of optical lenses, milling machines are required to grind the lenses to meet the usage specifications.

[0005] When using a milling machine to grind an optical lens, the optical lens is fixed to a suction cup and, driven by a cylinder, is placed into a dust cover and ground using the milling machine. However, the cylinder's pushing operation achieves linear motion by inflating and deflating air in a closed chamber, causing gaps between the gases. The friction coefficient between the piston and the closed chamber can cause secondary compression of the gases, making it difficult to precisely control the travel length of the optical lens. This often results in errors and can even cause the optical lens to collide with the milling machine or fail to accurately reach the milling machine's position. To address this issue, we propose a new drive mechanism for optical equipment to address this issue.

[0006] Utility model content.

[0007] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose a new driving mechanism for optical equipment.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a new driving mechanism for optical equipment is designed, comprising a cabinet, a placement table is provided above the cabinet, a manipulator for taking optical lenses is provided on the placement table, a milling machine for milling optical lenses is provided at one end of the cabinet, and the milling machine is fixed to the cabinet via a support frame;

[0009] The cabinet is a hollow shell, with a circular slot at one end of the cabinet close to the milling machine, a support tube built into the slot, a pneumatic suction cup at one end of the support tube close to the milling machine, and a connecting frame installed at the other end of the support tube, a movable seat installed at one end of the connecting frame, and the movable seat is connected to the screw rod through a nut thread, the screw rod is arranged along the axis direction of the support tube, and one end of the screw rod is rotatably mounted on the inner wall of the cabinet, and the other end of the screw rod is rotatably mounted on the first fixed seat, a drive motor is also installed on the end of the screw rod, and the drive motor is fixed on the first fixed seat.

[0010] Preferably, a guide shaft is provided parallel to the side of the support tube, the guide shaft slides through the connecting frame, one end of the guide shaft is fixed to the inner wall of the cabinet, and the other end of the guide shaft is fixed to the second fixing seat.

[0011] Preferably, an inlet and outlet are provided on one side of the cabinet, and a sealing door is detachably mounted on the inlet and outlet.

[0012] Preferably, a control cabinet is installed on the outer wall of the cabinet body, and a controller is provided in the control cabinet. The controller is connected to the controller and the milling machine through wires.

[0013] Preferably, the manipulator includes a linear motor arranged on one side of the top of the placement table, a lifting mechanism is installed on the linear motor, and a pneumatic claw for grabbing the optical lens is installed at the bottom of the lifting mechanism. The linear motor, lifting mechanism and pneumatic claw are all connected to the controller through wires.

[0014] Preferably, a dust cover is installed at one end of the milling machine close to the pneumatic suction cup, and an opening corresponding to the pneumatic suction cup is opened on the dust cover;

[0016] Preferably, a plurality of balls arranged at intervals are rollingly mounted on the inner wall of the slot.

[0017] The design scheme proposed by the utility model has the following beneficial effects during application:

[0018] The new driving mechanism used in this optical equipment rotates the screw to linearly drive the spiral connection on the moving base, thereby controlling the optical lens on the pneumatic suction cup to move closer to or away from the milling machine. The transmission of the screw can not only enable the pneumatic suction cup to move in a stable linear manner, but also rely on its own precision to achieve precise control of the moving distance of the pneumatic suction cup.

[0019] The new drive mechanism used in this optical device places multiple balls on the outer wall of the support tube, providing support for the support tube without affecting the linear motion of the support tube, ensuring that the support tube can perform linear motion more stably.

[0026] Specific implementation method.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figures 1-4 A new type of driving mechanism for optical equipment includes a cabinet 1, a placement table 2 is arranged above the cabinet 1, and a manipulator for picking up optical lenses is arranged on the placement table 2. The manipulator includes a linear motor 21 arranged on one side of the top of the placement table 2, a lifting mechanism is installed on the linear motor 21, and a pneumatic claw 22 for grabbing the optical lens is installed at the bottom of the lifting mechanism, which controls the pneumatic claw 22 to perform linear motion in the horizontal and vertical directions.

[0030] like Figure 3 and Figure 4 As shown, the cabinet body 1 is a hollow shell, and a circular slot 3 is provided at one end of the cabinet body 1 close to the milling machine 18. A support tube 4 is built into the slot 3, and a plurality of spaced balls 15 are rollingly installed on the inner wall of the slot 3 to provide support for the support tube 4, so that the support tube 4 can slide in the slot 3 with both effort and stability.

[0032] During the grinding process, in order to prevent the dust brought out by the pneumatic suction cup 5 when it is removed from the dust cover 16 from falling randomly, a dust collecting bag 20 with an open top is provided between the dust cover 16 and the support tube 4. One end of the dust collecting bag 20 is fixed to the support tube 4, and the other end of the dust collecting bag 20 is fixed to the dust cover 16, which is used to collect the dust brought out by the support tube 4 and the pneumatic suction cup 5.
