[0029] The working principle of the utility model is:

[0030] For example, Figure 1As shown, the application is fixedly arranged with a fixing frame 4 on the base plate 1, the fixing frame 4 is arranged with a positioning device which is located directly above the tin liquid tank 5; the application is arranged with a movable piece matched with the positioning device on the connecting frame 2, the connecting frame 2 is connected with a clamping device 3 for clamping and limiting the workpiece to be dipped in tin, the connecting frame 2 is rotatably arranged with a transmission roller 6, a fixed roller 21 is fixedly connected, a belt 22 is wound between the transmission roller 6 and the fixed roller 21, the transmission roller 6 is connected with a first rotary motor, the moving piece 61 is arranged on the transmission roller 6; when it is necessary to adjust the relative position of the clamping device 3 and the tin liquid tank 5, the first rotary motor drives the transmission roller 6 to rotate until the moving piece 61 on the transmission roller 6 faces upward (the fixed roller 21 does not rotate), when the transverse conveying device drives the connecting frame 2 to move in the horizontal direction, it will synchronously drive the clamping device 3 to move, when the moving piece 61 on the transmission roller 6 is limited in the positioning device, then the clamping device 3 is located directly above the tin liquid tank 5, the positioning device feedbacks the electrical signal to control the transverse conveying device to stop moving, the operator does not need to approach the cylinder for observation during the whole process, which reduces the safety hidden danger. As an embodiment 1, the transverse conveying device takes the telescopic cylinder as an example, then the telescopic amount of the telescopic cylinder can be observed, so as to set the moving stroke, so that the workpiece to be dipped in tin on the clamping device 3 can move to the tin liquid tank 5 during the dipping operation; since the moving piece 61 needs to be limited on the positioning device every time the dipping operation is performed, the positioning device has a certain impact force, so after being used for many times, the positioning device is prone to deformation or falling off. Therefore, the application sets the moving piece 61 in an adjustable state, when the relative position of the clamping device 3 and the tin liquid tank 5 is not tested, the first rotary motor drives the transmission roller 6 to drive the moving piece 61 to rotate to the downward state, thereby the design, when the clamping device 3 moves to the tin liquid tank 5, the positioning device does not contact with the moving piece 61, thereby prolonging the service life of the part.

As an embodiment of the first aspect, the vertical conveying device comprises a transmission frame 8, a screw rod 81 is arranged on the transmission frame 8, and the connecting frame 2 is installed on the screw rod 81. When the second rotary motor drives the screw rod 81 to rotate, the connecting frame 2 is driven to move in the vertical direction, so that the clamping device 3 moves up and down. As for the setting of the horizontal conveying device, a telescopic cylinder can be connected to the transmission frame 8, and a sliding rail for sliding cooperation of the transmission frame 8 is formed in the bottom plate 1. When the telescopic cylinder drives the transmission frame 8 to move in the horizontal direction, the transmission frame 8 drives the connecting frame 2 to move synchronously at this time, the connecting frame 2 drives the clamping device 3 to the top of the tin bath 5, and the guide rail 9 guides the movement track of the transmission frame 8.
