[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figure 1-6 As shown: In one embodiment, the present invention provides a technical solution: a thin copper sheet welding anti-oxidation mechanism, comprising a pin tooling turntable module 1, a pin electrode welding tooling module 2, and a connecting piece welding pressing module 3. The pin tooling turntable module 1 includes a turntable 1-1 and a first driving member 1-2 for driving the turntable 1-1 to rotate.

[0029] The 2-1 module has a section A connected to the turntable 1-1 and a section B 2-2 located outside the turntable 2-1. When section A rotates with the turntable 1-1, section B 2-2 also rotates with section A. A lifting module 4 is provided below section B 2-2. The connecting piece welding pressing module 3 has a pressing plate 3-1 and a second driving member that drives the pressing plate 3-1 to move up and down. The pressing plate 3-1 is used to press down the thin copper sheet located on the lead electrode welding fixture module 2.

[0030] In one embodiment, the connecting piece welding pressure module 3 is provided with a mounting base 3-3 for connecting the second driving component; the pressure plate 3-1 is L-shaped;

[0031] The mounting base 3-3 has a slide rail 3-3-1 on its side plate, and the pressure plate 3-1 has a slider 3-3-1 on its side plate.

[0032] 2. The slider 3-3-2 is connected to the pressure plate 3-1, and the slider 3-3-2 can move along the slide rail under the drive of the second driving component.

[0033] 3-3-1 moves up and down; the bottom plate of the pressure plate 3-1 is used to press down the thin copper sheet.

[0035] The air blowing tube seat 3-4 is provided with a screw hole that leads directly to the pipe 3-4-3. In use, the screw 3-4-4 can be screwed into the screw hole.

[0036] In this embodiment, the advantage of providing screw holes is that screws can be used for fixing, preventing the air tube 3-4-2 from swinging back and forth during air blowing, thus improving the accuracy of air blowing. The air tube is simply inserted into the channel. If the channel hole is too small, the air tube will be difficult to insert, so it is generally machined larger to accommodate the tube; that is, the maximum diameter of the air tube is smaller than the diameter of the channel hole. Therefore, the air tube is loose inside the channel, and it is also convenient to replace and disassemble the air tube. If the channel hole is made too small, forcing the air tube in will make replacement and disassembly inconvenient.

[0037] In one embodiment, the side plate of the pressure plate 3-1 is provided with an air blowing pipe seat 3-4, the air blowing pipe seat 3-4 is provided with a miniature elbow 3-4-1, and the air blowing pipe seat 3-4 is provided with a pipe 3-4-3 for connecting the miniature elbow 3-4-1 inside.

Two edges of the connecting piece are raised and are flush with the two long edges of the pin. During soldering, soldering is performed along the overlapping edge of the connecting piece and the pin.

[0043] In one embodiment, the gas output from the blowing pipe 3-4-2 is nitrogen.

[0044] In one embodiment, part A and part B 2-2 are integrally formed.

[0045] In one embodiment, part A and part B 2-2 are detachably connected.

The placement part is provided with a connecting piece positioning block 2-4, a first lead support plate 2-5, and a second lead support plate 2-6. Below the placement part are a first opening and closing block 2-7 and a second opening and closing block 2-10. Both the first opening and closing block 2-7 and the second opening and closing block 2-10 are provided with a top post. The top post can move up and down under the action of a lifting device. When the top post moves up and down, the first opening and closing block 2-7 and the second opening and closing block 2-10 open and close accordingly.

Both the first opening and closing block 2-8 and the second opening and closing block 2-9 are provided with a top post. The top post can move up and down under the action of a lifting device. When the top post moves up and down, the first opening and closing block 2-8 and the second opening and closing block 2-9 open and close accordingly.

[0048] In one embodiment, a compression spring 2-11 is provided between the first opening and closing block 2-8 and the second opening and closing block 2-9. When the top column moves upward, the first pin support plate 2-5 and the connecting piece positioning block 2-4 separate. In the natural state, one side of the first pin support plate 2-5 abuts against one side of the connecting piece positioning block 2-4.

[0049] In this embodiment, the opening and closing size between the first pin support plate 2-5 and the connecting piece positioning block 2-4 can be controlled by the upward movement distance of the top column, thereby achieving the purpose of positioning different thin copper sheets.

[0050] A method for preventing oxidation of the workpiece to be soldered is provided, wherein the steps of the method can be performed by the anti-oxidation mechanism for thin copper sheet soldering described in any of the above-mentioned embodiments.
