Referring to fig. 1 to 5, the utility model discloses a laser pre-welding device, which comprises a processing platform 10, a clamping assembly 20, a jacking assembly and a welding assembly 40, wherein the processing platform 10 is provided with a conveying channel which can convey a workpiece along the Y-axis direction, the clamping assembly 20 comprises two clamping mechanisms and a clamping driving piece 27, the two clamping mechanisms are arranged in pairs and are respectively positioned at two sides of the conveying channel, and the clamping driving piece 27 is used for driving the two clamping mechanisms to move along the X-axis direction so as to enable the two clamping mechanisms to be close to or far away from each other;
The pressing assembly comprises a pressing seat 31 and a pressing seat driving piece 32, wherein the pressing seat 31 is arranged above the processing platform 10 and above a space between two clamping mechanisms, the pressing seat driving piece 32 is used for driving the pressing seat 31 to move along the Z-axis direction, and in addition, at least two welding assemblies 40 are arranged, each two welding assemblies 40 are arranged in pairs and are respectively positioned at two sides of the processing platform 10 so as to weld two sides of a workpiece.
On the basis of the above structure, taking the Y-axis direction (as shown in fig. 1, i.e. the length direction of the processing platform 10) as an example of the conveying direction of the workpiece, in particular, in use, the battery is conveyed onto the conveying channel by a mechanical arm or a clamp or by a magnetic levitation technique, at this time, the clamping driving member 27 drives the two clamping mechanisms of the conveying channel to move close to each other along the X-axis direction (as shown in fig. 1, i.e. the width direction of the processing platform 10) to abut against the left and right sides of the workpiece so as to clamp the left and right sides of the workpiece in the X-axis direction, then the pressing seat driving member 32 is started to drive the pressing seat 31 to move downward along the Z-axis direction (as shown in fig. 1, i.e. the height direction of the processing platform 10) to abut against the upper side of the workpiece so as to clamp the left and right sides of the workpiece, thus, the displacement of the workpiece during the welding process can be avoided, and the welding quality of the workpiece can be improved, and thereafter, the welding assemblies 40 on both sides of the workpiece are welded synchronously by synchronously.
Specifically, when the laser pre-welding device in this embodiment is applied to the field of battery processing, a workpiece is taken as an example of a square battery to describe, and when the aluminum shell and the cover plate of the battery are specifically required to be welded together, the cover plate and the aluminum shell are transferred into a conveying channel through an automatic technology such as a mechanical arm or a clamp, the cover plate is placed above the aluminum shell, at this time, a pressing seat 31 presses the cover plate downwards along the Z-axis direction under the driving of a pressing seat driving piece 32, so that the cover plate and the aluminum shell are tightly attached and are not easy to loosen, and meanwhile, a clamping mechanism is driven by a clamping driving piece 27 to mutually approach to clamp the left side and the right side of the aluminum shell, so as to complete the positioning and clamping action before the pre-welding of the cover plate and the aluminum shell, and after the clamping and positioning action is completed, two groups of welding assemblies 40 on two sides of the conveying channel synchronously weld the gaps on the aluminum shell and the two sides of the cover plate, so that the aluminum shell and the cover plate are welded together;
