Description

Technical Field

[0001] The utility model relates to the field of automatic lens production, in particular to a jaw manipulator structure for a lens marking machine. Background Technique

[0002] In the process of lens production, after the lens is polished, it needs to be marked continuously. Most of the existing marking machines on the market use vacuum suction cups to grab the lenses. Using such a structure of vacuum suction cups will leave marks on the surface of the polished lenses, inevitably reducing the quality of the lenses. However, because when the lens is placed at the marking position, it needs to be pressed down to ensure that the lens fits the marking position, so it is also not advisable to use ordinary jaws to grab the lenses. Because the edges of some lenses are relatively thin, when the jaws grab the lens and press it down, the edges of the lens are extremely easy to break. If a flexible jaw is used to grab the lens, the jaw itself is easily damaged by the edge of the thin lens, and the service life is low. Summary of the Invention

[0003] To solve the above technical problems, the purpose of the utility model is to provide a jaw manipulator structure for a lens marking machine, which includes a fixed seat, a swing arm member and a jaw member. The swing arm member and the jaw member are installed on the fixed seat to achieve self-positioning. The swing arm member is in transmission cooperation with the jaw member, that is, the swing arm member drives the jaw member to achieve displacement through the swing arm it has. The jaw member has at least two jaws arranged oppositely, that is, the jaw member can clamp the lens from both sides through the jaws.

[0004] Preferably, the swing arm member further includes a speed reducer and a motor for driving the swing arm. The jaw member is fixedly arranged at the front end of the swing arm, that is, the speed reducer and the motor drive the jaw member to achieve displacement.

[0004]

[0005] Preferably, the fixed seat includes a cross plate and two side plates. The motor is fixedly arranged on the cross plate. The speed reducer is in transmission connection with the motor. The rear end of the driving swing arm is in transmission connection with the speed reducer. The front end of the driving swing arm has a jaw member mounting plate.

[0006] Preferably, the jaw member further includes a double-acting cylinder and a pneumatic finger cylinder. The pneumatic finger cylinder is in transmission connection with the driving end of the double-acting cylinder. The jaw member is fixedly installed on the jaw member mounting plate through the double-acting cylinder. Two jaw mounting blocks are arranged oppositely and are respectively fixedly installed on the two driving ends of the pneumatic finger cylinder. Each jaw is fixedly installed on the corresponding jaw mounting block.

[0005]

[0007] Preferably, each jaw includes two clamping columns, and the two clamping columns are arranged oppositely and fixedly installed on the jaw mounting block.

[0008] Preferably, two mounting through-holes are formed in the jaw mounting block. Each clamping column includes an inner column body. The upper end of the inner column body has a plug-in head that matches the mounting through-hole. The inner column body is made of stainless steel, and the outer periphery of the inner column body further has an intermediate silica gel layer and a contact linen layer from inside to outside.

[0009] Preferably, the fixed seat is provided with a limiting block at the cross plate, and the swing arm is provided with a blocking block that matches the limiting block at the cross plate.

[0010] By means of the above solution, the present utility model has at least the following advantages:

[0011] 1. The present utility model uses jaws to grasp the lens. Compared with using a suction cup, it can avoid contacting the surface of the polished lens and avoid damaging the fine surface of the polished lens.

[0012] 2. The jaws adopt a special design. Not only each jaw is composed of two clamping columns, but also each clamping column has a three-layer structure. Its innermost layer is stainless steel for support; the middle layer is silica gel to reduce the hardness of clamping, thereby reducing the possibility of damage to the lens edge; the outermost layer is linen material, which can protect the silica gel tube in the middle layer from being cut by the thin lens edge. In this way, it not only ensures that the contact with the lens edge is soft, but also ensures the service life of the jaws.

[0013] 3. The swing arm is driven by a motor. Compared with other methods of driving the swing arm by a cylinder, it improves the service life and the in-place accuracy of the robotic arm.

[0031] The working principle of the present utility model is as follows:

[0032] When the motor 7 is started, it drives the swing arm 4 through the reducer 6. After it reaches the lens clamping station, the double-acting cylinder 11 drives the pneumatic finger cylinder 12 to move downward. Then, the pneumatic finger cylinder 12 changes from the open state to the closed state, thereby driving the two jaws 5 to clamp the lens. After clamping the lens, the double-acting cylinder 11 drives the pneumatic finger cylinder 12 to move upward. The motor 7 continues to drive the swing arm 4 to rotate to the lens marking station. Then, the double-acting cylinder 11 drives the pneumatic finger cylinder 12 to move downward again. When the lens fits the marking station, the double-acting cylinder 11 stops working, and the pneumatic finger cylinder 12 drives the two jaws 5 to release the lens.

[0033] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
