[0002] As is well known, in the technical field of new energy vehicle technology, with the increasing development of CCS busbar integration technology, flexible printed circuit boards, that is, FPCs, are commonly used in battery interconnection systems and are also a relatively large cost expenditure. FCC flexible flat cables appear as a substitute for the wire harness and FPC in CCS. Among them, the laser soldering process technology and equipment in the subsequent process of the SMT mounting technology, which is one of the important processes of FCC, have also been correspondingly developed. In the manufacturing process of FCC, the product quality of operations such as welding NTC branches and copper branches depends to a large extent on the positioning accuracy of the main and auxiliary boards and the flatness of the chip mounting. Because in the existing FCC welding technology process, due to the close fit between the FCC and the metal jig, and because the following metal jig has the property of rapid heat conduction, some of the welding heat at the welding position will be absorbed by the metal jig, resulting in unstable welding temperatures of the workpieces to be welded, that is, not reaching the predetermined value, which will cause poor phenomena such as false soldering or incomplete welding. Also, phenomena such as workpiece offset will affect the subsequent SMT process, resulting in a decrease in the overall product yield rate, affecting the overall product quality, and increasing production costs. Therefore, an integrated welding jig that has stable positioning, keeps the welding temperature of the workpieces stable, and can effectively improve the welding yield rate of products is needed.

Detailed implementation manner

[0019] To facilitate the understanding of the present invention, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0020] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated therewith, or there may be an intermediate element at the same time. The terms "installation", "one end", "the other end" and similar expressions used herein are only for the purpose of illustration.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this technology belongs. The terms used in the description of the present specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] Refer to Figure 1-2 , the present utility model provides an integrated welding jig, including a carrier board assembly 1 and a cover plate assembly 2. The carrier board assembly 1 is movably connected to the cover plate assembly. The carrier board assembly 1 is provided with a plurality of processing slots 2 and a plurality of high-temperature resistant connecting pieces 11. Each processing slot is distributed at intervals on the carrier board assembly, and each high-temperature resistant connecting piece 11 is evenly distributed on the carrier board assembly 1 near the processing slots. The high-temperature resistant connecting piece 11 is used to connect the cover plate assembly and press and position the workpiece to be processed in the processing slot 2. A low-temperature conduction piece 4 is provided on the processing slot 2. The low-temperature conduction piece 4 is used to keep the temperature of the workpiece to be processed in the processing slot 2 within a stable range. Because the overall welding jig is an aluminum alloy frame, the aluminum alloy will absorb the heat generated by the laser during laser welding processing, resulting in a reduction in the heat transferred to the product pad. The heat conduction effect of the rectangular composite stone piece is relatively low compared to that of the metal, which can prevent the carrier board from absorbing the heat generated by the laser and avoid the phenomenon of insufficient welding temperature caused by the heat absorption of the metal material carrier board assembly around the pad, effectively improving the welding yield of the FCC product.

[0023] Refer toFigure 1-2 , in a further preferred embodiment, the carrier board assembly 1 includes a carrier board body 10, the carrier board body 10 is a metal material carrier board body, the cover plate assembly includes a cover plate body 23, and the cover plate body 23 is detachably connected to the carrier board body 10 by a magnetic attraction connection method, which is convenient for the opening and connection of the cover plate body 23 and the carrier board body 10. The carrier board body 10 is an integrated carrier board design, and several holes required for the integrated welding process are located integrally. After placing the FFC, the situation of FFC offset caused by the transfer and taking of multi-section fixtures can be avoided, and adverse effects on the subsequent SMT process can be avoided.

[0024] Reference Figure 1-2 , as a further preferred embodiment, the high-temperature resistant connecting piece 11 is a circular high-temperature resistant magnet unit. There are multiple groups of circular high-temperature resistant magnet units, and each group includes at least four or more circular high-temperature resistant magnet individuals. Each circular high-temperature resistant magnet individual is evenly distributed on the carrier board body or on the processing slot 2. The cover plate body 23 can be magnetically attracted to the carrier board body to press and fix the FFC to be processed and welded.

A rectangular composite stone piece is also embedded in the rectangular sunk groove. The rectangular composite stone piece is also the low-temperature conduction piece 4. The rectangular composite stone piece is used to avoid the phenomenon of stable workpiece welding temperature caused by the metal carrier board absorbing heat during workpiece welding. Because the rectangular composite stone piece has the performance of low-temperature conduction, it can keep the heat on the rectangular sunk groove from being absorbed by the metal carrier board body, and can prevent the metal carrier board around the pad from absorbing heat too quickly during welding processing, resulting in insufficient welding temperature, effectively improving the welding yield of the FCC product. A carrier board positioning post 5 is also provided on the processing slot 2, corresponding to the opening 22 on the cover plate body.

Among them, every three are arranged at intervals in a column and are respectively arranged on the upper and lower sides of the carrier body. Corresponding positioning bump openings 20 that match the positioning bumps are provided on the cover sheet body 23, which facilitates the alignment of the FCC workpiece and is also more conducive to the connection between the carrier body and the cover sheet body.

Corresponding limiting post openings 16 that match the limiting posts 7 are provided on the cover sheet body. The provided limiting posts 7 and the corresponding limiting post openings 16 can prevent the cover sheet body 23 and the carrier body 10 from being misaligned when they are attached, and the FCC positioning from being misaligned due to the cover sheet body 23 rubbing against the FFC, so that the cover sheet body 23 cannot accurately attach and press the FFC.
