the driving device 2 can drive the substrate 13 to move towards the direction close to or away from the limiting plate 3, the locking mechanism 4 moves the floating mechanism 1 and the substrate 13 synchronously, and then the workpiece to be processed on the floating mechanism 1 moves towards the direction close to or away from the limiting plate 3, so that the workpiece to be processed is compressed or released.
In one example, the driving device 2 drives the substrate 13 to slide along the bracket assembly 14, so as to drive the locking mechanism 4, the floating mechanism 1 and the substrate 13 to move synchronously.
The pressure sensor 11 is used for detecting pressure information between a workpiece 15 to be processed and the limiting plate 3;
in one example, the pressure information of the workpiece 15 to be processed and the stopper plate 3 may be determined from the resistance information of the substrate.

In one example, in the case that the pressure sensor detects that the pressure information between the workpiece 15 to be processed and the limiting plate 3 reaches the preset pressure threshold, it is determined whether the displacement information of the substrate is within the preset moving distance range, and if so, the driving member 402 in the locking mechanism 4 is controlled to move in the direction away from the floating mechanism 1 to release the floating plate 102, so that the floating plate 102 floats to press the workpiece 15 to be processed.
In some exemplary embodiments, a method of controlling a welding fixture: controlling the locking mechanism 4 to lock the floating mechanism 1; under the condition that the workpiece 15 to be processed is detected to exist on the floating mechanism 1, the driving device 2 is controlled to drive the locking mechanism 4, the floating assembly 1 and the workpiece 15 to be processed to move towards the direction close to the welding protection device 5, and under the condition that the detected pressure information reaches a preset pressure threshold value and the displacement information of the substrate is smaller than or equal to a preset moving distance range, the locking mechanism 4 is controlled to release the floating mechanism 1, so that the floating mechanism 1 floats and compresses the workpiece 15 to be processed.
The working principle of the welding positioning device system is as follows:
when a workpiece to be processed needs to be welded, the workpiece 1 to be processed is moved to the floating plate 102 of the floating mechanism 1, the driving device 2 is controlled to drive the substrate 13 to move along the bracket assembly in the direction close to the welding protection device 5 on the limiting plate 3, and then the locking mechanism 4, the floating mechanism 1 and the workpiece 15 to be processed are driven to ascend until pressure information between the workpiece 15 to be processed and the welding protection device 5 reaches a preset pressure threshold value and displacement information of the substrate is smaller than or equal to a preset moving distance range; controlling a driving piece 402 in the locking mechanism 4 to drive a jacking piece 403 to move away from the floating mechanism 1 so as to release the floating plate 102, and further enabling the floating plate 102 to float and press the workpiece 15 to be processed;
after the workpiece to be processed is welded, the driving device 2 is controlled to drive the substrate 13 to move in the direction away from the limiting plate 3, so that the workpiece to be processed 15 is far away from the welding protection device, and the workpiece to be processed 15 is moved out of the floating mechanism 1 to be processed in the next step, so that the welding of the workpiece to be processed 15 is completed.
This application mechanism is simple, and easy operation not only can reduce the quantity of protective gas, and it is long when reducing the welded, stability when can also guaranteeing the welding.
The above disclosure is only one preferred embodiment of the present application, and certainly does not limit the scope of the present application, which is therefore intended to cover all modifications and equivalents of the claims.
