[0017] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] Reference Figure 1-4, is a single-guide rail mechanical arm used in an impregnation line disclosed in the utility model, comprising a frame 3, on which a lifting device 1 is provided, the lifting device 1 is connected to a clamping device 4 and drives the clamping device 4 to move up and down along the height direction of the frame 3, the lifting device 1 comprises a power mechanism and a connecting mechanism, the power mechanism drives the connecting mechanism to move, the connecting mechanism is slidably connected to the frame 3 through a guide mechanism 2, and the clamping device 4 is provided on the connecting mechanism; the guide mechanism 2 comprises a single guide rail 21 installed on the frame 3, a guide rail slider 22 is slidably connected to the single guide rail 21, and the guide rail slider 22 is connected to the connecting mechanism.

[0020] The frame 3 includes a transverse plate 31 and two vertical plates 32 vertically fixed to the two ends of the transverse plate 31. A single guide rail 21 is installed on the opposite side of the two transverse plates 31. The two corresponding single guide rails 21 can support and connect the connecting mechanism on both sides, so that the movement of the connecting mechanism is more stable.

[0021] The power mechanism includes a reducer 11 and a power motor 12, and the power motor 12 and the reducer 11 are installed on the cross plate 31. The power motor 12 and the reducer 11 can be connected to the connecting mechanism through transmission parts such as chains. When the power motor 12 and the reducer 11 are running, the transmission parts can drive the connecting mechanism to move up and down.

[0022] The connecting mechanism includes a lifting frame, and the guide rail sliders 22 are installed on both sides of the lifting frame. When the lifting frame moves under the action of the power mechanism, it also slides with the single guide rail 21 through the guide rail sliders 22, so that the movement of the lifting frame is more stable, thereby ensuring the stability of the clamping device 4 when the workpiece basket is moved.

[0023] The clamping device 4 includes two symmetrically arranged clamping jaws 41 and a pneumatic part. The two clamping jaws 41 are slidably arranged on the lifting frame. The pneumatic part includes a cylinder. The cylinder is arranged on the lifting frame. The cylinder connects the two clamping jaws 41 and drives the clamping jaws 41 to move. The extension and retraction of the cylinder enables the two clamping jaws 41 to approach or move away from each other at the same time, thereby realizing the clamping and releasing actions, and achieving the purpose of clamping and releasing the workpiece basket.

[0024] The implementation principle of the utility model is: when the power mechanism is running, it can drive the lifting frame to move. During the movement of the lifting frame, the guide rail slider 22 cooperates with the single guide rail 21 to slide. As the lifting frame rises and falls, the clamping device 4 can move to the height position corresponding to the workpiece basket, and then the clamping device 4 operates to clamp the workpiece basket.
