[0039] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0040] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0041] like Figure 1-Figure 6 The flat wire 30 fixing device shown can be used to fix the flat wire 30. After the flat wire 30 is fixed, it is convenient to process the two ends of the flat wire 30. The flat wire 30 fixing device includes a working platform 10, the working platform 10 includes a first plane 11 and a second plane 12, a step 13 is arranged between the first plane 11 and the second plane 12, a flat surface of the flat wire 30 is placed on the second plane 12, and a side surface of the flat wire 30 abuts against the step 13;

[0042] The clamping mechanism 20 includes at least one first clamping mechanism 21 disposed on the first plane 11, wherein the first clamping mechanism 21 includes a first connecting rod assembly 211 and a first clamping head 212 driven by the first connecting rod assembly 211 and having a dead point position, wherein the first clamping head 212 at the dead point position presses another flat surface of the flat wire 30 to limit the position of the flat wire 30 in the Z direction.

[0043] And, at least one second clamping mechanism 22 is arranged on the second plane 12, the second clamping mechanism 22 includes a second connecting rod assembly 221 and a second chuck 222 which is moved by the second connecting rod assembly 221 and has a dead point position, the second chuck 222 at the dead point position presses the other side of the flat wire 30 to limit the flat wire 30 in the Y direction.

[0044] After the flat wire 30 is cut, the clamping mechanism 20 can be used to position and fix the flat wire 30, and then the two ends of the flat wire 30 are milled to ensure that the contact surface at the end of the flat wire 30 and the contact surface of the terminal meet the requirements of stir friction welding. Due to the fixing effect of the clamping mechanism 20, the flat wire 30 has better stability during welding, thereby improving the welding qualification rate of the product and reducing the welding risk caused by raw materials.

[0045] By limiting the flat wire 30 in the Z direction through the first clamping mechanism 21 and limiting the flat wire 30 in the Y direction through the second clamping mechanism 22, human control deviation during blanking of the aluminum flat wire 30 is avoided, thereby improving the welding qualification rate.

[0046] like Figure 1 and Figure 2 As shown, in order to ensure the stability of fixing the flat wire 30 , the first clamp 212 at the dead point is perpendicular to the other flat surface of the flat wire 30 , and the second clamp 222 at the dead point is perpendicular to the other side surface of the flat wire 30 .

[0047] like Figure 3 and Figure 4 As shown, specifically, the first clamping mechanism 21 includes a first base 213, a first connecting rod assembly 211 and a first handle 214. The first base 213 includes a first bottom plate portion 2131 and a first support portion 2132. The first bottom plate portion 2131 is fixedly connected to the first plane 11, and may be screwed. The first connecting rod assembly 211 includes a straight first connecting rod 211a and an L-shaped second connecting rod 211b. The first fixed axis 2111 is formed at the connection between one end of the first connecting rod 211a and the first support portion 2132. The other end of the first connecting rod 211a is rotatably connected to the first handle 214. One end of the second connecting rod 211b is connected to the first support portion 2132 to form a second fixed axis 2112. The bending portion of the second connecting rod 211b is rotatably connected to the first handle 214. The other end of the second connecting rod 211b is connected to the first clamp 212.

[0048] During the specific operation, the first handle 214 is lifted to drive the first connecting rod 211a to make a mechanical circular motion at the first fixed axis 2111, and at the same time drive the second connecting rod 211b to make a mechanical circular motion at the second fixed axis 2112, thereby driving the first clamping head 212 to be lifted upward;

[0049] Pressing the first handle 214 drives the first connecting rod 211a to make a mechanical circular motion at the first fixed axis 2111, and drives the second connecting rod 211b to make a mechanical circular motion at the second fixed axis 2112, thereby driving the first clamping head 212 to be pressed against the flat wire 30. This ensures that the second clamping mechanism 22 limits the flat belt in the Z direction.

[0050] Furthermore, the first support portion 2132 and the first handle 214 are hingedly connected to the first connecting rod assembly 211 .

[0051] like Figure 5 and Figure 6 As shown, the second clamping mechanism 22 includes a second base 223, a second connecting rod assembly 221 and a second handle 224. The second base 223 includes a second bottom plate portion 2231 and second supporting portions 2232 and a second fixing portion 2233 arranged on both sides of the second bottom plate portion 2231. The second bottom plate portion 2231 is fixedly connected to the second plane 12.

[0052] The second connecting rod assembly 221 includes a connecting rod 221a and a sliding shaft 221b that are mutually connected. The ends of the second handle 224 are respectively connected to the second supporting portion 2232 and one end of the connecting rod 221a. The sliding shaft 221b passes through the second fixing portion 2233 and is movably connected to the other end of the connecting rod 221a.

[0053] In specific operation, when the second handle is lifted, the connecting rod 221a and the sliding shaft 221b are driven to perform mechanical movement, so that the sliding shaft 221b is mechanically moved backward; when the second handle 224 is pressed, the connecting rod 221a and the sliding shaft 221b are driven to perform mechanical movement, so that the sliding shaft 221b is mechanically moved forward, thereby ensuring that the second clamping mechanism 22 limits the flat wire 30 in the Y direction.

[0054] like Figure 1 and Figure 2 As shown, the top of the sliding shaft 221b can also be connected to a baffle 40 to increase the contact surface with the flat wire 30 and better fix the flat wire 30. The baffle 40 is screwed to the end of the sliding shaft 221b in a plane, and the baffle 40 abuts against the side of the flat wire 30.

[0055] In one embodiment, both the first clamping mechanism 21 and the second clamping mechanism 22 can be one, respectively arranged on the first plane 11 and the second plane 12; in another embodiment, there are multiple first clamping mechanisms 21, and multiple first clamping mechanisms 21 are arranged at intervals on the first plane 11 along the extension direction of the working platform 10; there are multiple second clamping mechanisms 22, and multiple second clamping mechanisms 22 are arranged at intervals on the second plane 12 along the extension direction of the working platform 10.

[0056] In one embodiment, in order to ensure that an equal force is applied to each position of the flat wire 30 , the first clamping mechanism 21 and the second clamping mechanism 22 are correspondingly disposed along a direction perpendicular to the flat wire 30 .

[0057] like Figure 3 As shown, the first base 213 and / or the second base 223 are bolted to the work platform 10 through the screw hole 50.
