[0002] In the process of producing busbars using flat wires through a stir friction welding process, in order to ensure that the weld between the end of the flat wire and the terminal to be welded is tight, lead-in blocks and lead-out blocks are generally added during the welding process to assist welding. Figure 1 As shown, in which: 101 is a flat wire, 102 is a terminal, 103 is an introduction block, 104 is a lead-out block, a is a welding starting point, b is a welding end point, the connection direction of a and b is the welding direction, and the whole after the flat wire and the terminal are welded is called a bus.
[0003] Before welding, place the flat wire and the terminal on the corresponding welding tool, and then after the flat wire and the terminal are fixed in place, use the stirring needle in the welding tool to weld the flat wire and the terminal along the welding direction, thereby achieving a tight weld between the flat wire and the terminal. After welding is completed, the flat wire and the terminal as a whole form a bus, and at this time the lead-in block and the lead-out block will also be welded to the bus. In order to remove the lead-in block and the lead-out block, the existing operation is to remove the bus with the lead-in block and the lead-out block from the welding tool, and then place it on the cutting tool for cutting. However, this removal method not only requires the provision of two tools, but also requires the frequent switching of the two tools.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] like Figure 2-Figure 8 As shown, a processing device for busbar welding includes a base 1 and a clamp arranged on the base 1, the clamp includes a fixed support platform 3 and two movable support platforms 2 arranged on the base 1, the two movable support platforms 2 are respectively arranged on both sides of the fixed support platform 3, and the two movable support platforms 2 can move closer or farther away. Specifically, the clamp also includes a driving member for driving the two movable support platforms 2 to move closer or farther away, the driving member includes two groups of direct push cylinders 7 arranged on the base 1, and the two groups of direct push cylinders 7 are arranged along the connecting direction of the two movable support platforms 2, and the piston ends of the two groups of direct push cylinders 7 are respectively fixedly connected to the corresponding movable support platforms 2.
[0035] During the processing, the lead-in block 103 and the lead-out block 104 that need to be set are respectively set on the top of the two mobile support platforms 2, and the end to be processed of the main body composed of the flat wire 101 and the terminal 102 in abutting state is set on the top of the fixed support platform 3. The movement of the two mobile support platforms 2 can drive the lead-in block 103 and the lead-out block 104 thereon to follow. Then, when the two mobile support platforms 2 are driven to make similar movements by two sets of direct-push cylinders 7 until both mobile support platforms 2 collide with the fixed support platform 3, the lead-in block 103 and the lead-out block 104 are distributed on both sides of the end to be processed and clamp the main body, and at this time, the clamped main body and the lead-in block 103 and the lead-out block 104 can be welded. After welding is completed, two sets of direct-push cylinders 7 are used to drive the two movable support platforms 2 to move apart until the two movable support platforms 2 are away from the fixed support platform 3. At this time, processing gaps are formed between the two movable support platforms 2 and the fixed support platform 3. The part of the lead-in block 103 in contact with the main body will be located above one of the processing gaps, and the part of the lead-out block 104 in contact with the main body will be located above the other processing gap, that is, the contact parts at the two locations are respectively exposed above the two processing gaps. Subsequently, a cutting knife is used to extend into the processing gap and cut the contact parts, so that the lead-in block 103 and the lead-out block 104 can be removed. After removal, a grinding sheet is extended into the processing gap to grind the burrs on the side of the main body after cutting.

The existence of the processing gap can provide an operating space for the work of the cutting knife, and the lead-in block 103 and the lead-out block 104 can be cut without adding additional cutting tooling. It is easy to use and the efficiency of the welding processing is improved.
[0037] like Figure 3-Figure 4 As shown, for the position limiting setting of the fixed support platform 3 on the main body, a second groove 5 can be opened on the top of the fixed support platform 3, and the second groove 5 is used to accommodate the end of the main body to be processed. At the same time, first grooves 4 can also be opened on the tops of the two movable support platforms 2, and the two first grooves 4 are used to accommodate the introduction block 103 and the lead-out block 104 respectively.
[0038] In the process of using two sets of direct-push cylinders 7 to drive the two mobile support platforms 2 to perform similar actions until the two mobile support platforms 2 are in contact with the fixed support platform 3, in order to make the two mobile support platforms 2 and the fixed support platform 3 contact stably and accurately, a limiting protrusion 13 can be provided on the side where the two mobile support platforms 2 can contact with the fixed support platform 3, and limiting notches 12 for the corresponding limiting protrusions 13 to be inserted and abutted are provided on both sides of the fixed support platform 3.

Specifically, the pressing member includes three groups of pressing cylinders 8 arranged on the base 1, and the piston ends of the three groups of pressing cylinders 8 are all provided with a top plate 9, and the three top plates 9 are respectively located above the lead-in block 103, the terminal 102 and the lead-out block 104. Figure 2 In the state shown, the three top pressure cylinders 8 can respectively drive the three top plates 9 to move downward, so that the three top plates 9 respectively press the lead-in block 103, the terminal 102 and the lead-out block 104, thereby ensuring stability during the welding process.

The setting of the protective cover plates 14 can not only suppress and limit the lead-in block 103, the lead-out block 104 and the end to be processed of the main body, but also protect the parts of the lead-in block 103, the lead-out block 104 and the end to be processed of the main body that do not need to be welded, and normal welding work can be carried out by exposing the seams to be welded using the through holes 15 thereon.
