When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0023] like Figure 1 and Figure 2 As shown, the present application discloses a welding strip flattening device, which includes a multi-force cylinder 100, a supporting platform 200, a base 300, a first limiting member 400 and a pressing member 500.

[0024] Specifically, the base 300 is arranged on the supporting platform 200, and the double-force cylinder 100 is arranged on the base 300. The base 300 is provided with a first through hole A and a second through hole B facing the supporting platform 200. The first through hole A is adjacent to the second through hole B. The first limiting member 400 and the pressing member 500 are both connected to the driving end of the double-force cylinder 100. The pressing member 500 is slidably matched with the second through hole B. The pressing member 500 can press the pressing section of the welding strip carried by the supporting platform 200 to deform it. The first limiting member 400 is slidably matched with the first through hole A. The first limiting member 400 can be limitedly matched with the first limiting section of the welding strip in the vertical direction. The first limiting section is adjacent to and connected to the pressing section.

[0025] During the use of the welding strip flattening device, the supporting platform 200 carries the welding strip, and the double-force cylinder 100 drives the first limiting member 400 and the pressing member 500 to move close to the welding strip to achieve the effect of one thing serving two purposes. The first limiting member 400 cooperates with the first limiting section in the vertical direction, and the pressing member 500 presses the pressing section of the welding strip to deform it. Since the first through hole A is adjacent to the second through hole B, the first limiting section is adjacent to and connected to the pressing section. When the pressing section of the welding strip is deformed by the pressing member 500, the first limiting member 400 cooperates with the first limiting section, so that the pressing force of the first limiting member 400 and the bending stress of the first limiting section and the deformation stress of the pressing section are offset, thereby preventing the welding strip from warping, skewing, etc., thereby ensuring the flattening effect of the welding strip.

[0026] In an embodiment of the present application, the disclosed welding strip flattening device may further include a second limiting member, the base 300 is further provided with a third through hole, the second through hole B is located between the first through hole A and the third through hole, the third through hole is adjacent to the second through hole B, the second limiting member is slidably matched with the third through hole, the first limiting member 400, the pressing member 500 and the second limiting member are all connected to the driving end of the double force cylinder 100, the second limiting member can be limitedly matched with the second limiting section of the welding strip in the vertical direction, the second limiting section is adjacent to and connected to the pressing section, and the pressing section is located between the first limiting section and the second limiting section.

[0027] The above-mentioned mechanism drives the first limit member 400, the pressing member 500 and the second limit member to move close to the welding strip through the multiplying cylinder 100. When the pressing section of the welding strip pressed by the pressing member 500 is deformed, the first limit member 400 cooperates with the first limit section to limit, so that the pressing force of the first limit member 400 and the bending stress of the first limit section and the deformation stress of the pressing section are offset. The second limit member cooperates with the second limit section to limit, so that the pressing force of the second limit member and the bending stress of the second limit section and the deformation stress of the pressing section are offset, thereby further preventing the welding strip from warping, skewing, etc., thereby improving the flattening effect of the welding strip.

[0028] In an embodiment of the present application, the disclosed welding strip flattening device may further include a first spring 600. Specifically, the first spring 600 elastically contacts between the first limiting member 400 and the first through hole A. The deformation potential energy of the first spring 600 is used to store part of the kinetic energy driven by the multiplier cylinder 100, thereby realizing flexible pressing of the first limiting member 400 on the first limiting section, thereby preventing the first limiting section from being damaged by rigid pressing.

[0029] In a further technical solution, the first limit member 400 may include a guide column section 410, a second spring 420 and a pressure head section 430. Specifically, the guide column section 410 and the pressure head section 430 are both slidably matched with the first through hole A, one end of the guide column section 410 is in contact with the driving end of the double-force cylinder 100, and the other end of the guide column section 410 is elastically connected to one end of the pressure head section 430 through the second spring 420. The first spring 600 is sleeved on the pressure head section 430, and the first spring 600 elastically contacts between the pressure head section 430 and the first through hole A.

[0030] More kinetic energy driven by the multiplying force cylinder 100 is further stored through the deformation potential energy of the first spring 600 and the second spring 420, so as to further realize the flexible pressing of the first limiting member 400 on the first limiting section.

[0031] In the embodiment of the present application, the disclosed welding strip flattening device may further include a third spring 700. Specifically, one end of the pressing member 500 contacts the driving end of the double-force cylinder 100, and the third spring 700 is sleeved on the pressing member 500, and the third spring 700 elastically abuts between the pressing member 500 and the second through hole B. The third spring 700 is deformed when the pressing member 500 moves, and part of the driving kinetic energy of the double-force cylinder 100 is converted into elastic potential energy, thereby reducing the pressing force of the pressing member 500 on the pressing section and achieving flexible pressing.

[0032] In the embodiment of the present application, both the first limit member 400 and the pressing member 500 can be multiple. Specifically, along the first direction, multiple first limit members 400 are arranged in an array, and the pressing members 500 are arranged in an array. The multiple first limit members 400 and the multiple pressing members 500 are arranged in an array one by one along the second direction and are spaced apart, and are all connected to the driving end of the double-force cylinder 100, wherein the first direction and the second direction intersect vertically.

[0033] The plurality of first limiting members 400 and the plurality of pressing members 500 can be used to flatten the plurality of welding strips, thereby improving the working efficiency.

[0034] In the embodiment of the present application, the distance between the first limiting member 400 and the supporting platform 200 may be greater than the distance between the pressing member 500 and the supporting platform 200, so that before the pressing section of the pressing member 500 pressing the solder strip is deformed, the first limiting member 400 cooperates with the first limiting section to fix the first limiting section relative to the supporting platform 200, thereby preventing the solder strip from being displaced when the pressing member 500 is pressed, thereby ensuring the flattening effect of the solder strip.

[0035] In an embodiment of the present application, a groove may be provided at a position relative to the support platform 200 and the pressing member 500. Specifically, when the pressing member 500 presses the pressing section to deform it, the groove and the pressing section are limitedly matched along the width direction thereof, thereby making the deformation width of the pressing section controllable.

[0036] In the embodiment of the present application, the distance between the first limiting member 400 and the supporting platform 200 is greater than the distance between the pressing member 500 and the supporting platform 200, and the distance between the second limiting member and the supporting platform 200 is greater than the distance between the pressing member 500 and the supporting platform 200, so that before the pressing section of the pressing member 500 pressing the solder strip is deformed, the first limiting member 400 cooperates with the first limiting section to fix the first limiting section relative to the supporting platform 200, thereby preventing the solder strip from being displaced when the pressing member 500 is pressed, thereby ensuring the flattening effect of the solder strip.
