The shaping assembly 300 comprises a second mounting seat 310 and a second push rod 320, the second mounting seat 310 and the opening 102 are located on the same side of the fixing assembly 100 along the first direction Z, the second push rod 320 is connected to the side of the second mounting seat 310 facing the fixing assembly 100, and the second push rod 320 is movable along the second direction X and is used for pressing the bent flexible circuit board 3.

[0054] After the battery cell 2 with the flexible circuit board 3 is installed to the positioning groove 101, a part of the flexible circuit board 3 is stretched out from the opening 102, then the first push rod 220 is controlled to move relative to the first mounting base 210, the first push rod 220 gradually approaches the fixed assembly 100 to contact the part of the flexible circuit board 3 stretched out from the opening 102, and drives the flexible circuit board 3 to start bending, after the flexible circuit board 3 is bent in place, the first push rod 220 resets to be away from the fixed assembly 100, then the second push rod 320 is controlled to move relative to the second mounting base 310, the second push rod 320 gradually approaches the fixed assembly 100 to contact the part of the flexible circuit board 3 stretched out from the opening 102, and drives the flexible circuit board 3 to keep in the bent state, finally the second push rod 320 resets to be away from the fixed assembly 100, and the bending of the flexible circuit board 3 is completed.

[0055] The flexible circuit board bending mechanism 1 can not only bend and press the flexible circuit board 3, but also has simple structure, low design cost, and is open around, so that the product processing state can be observed, the risk of scratches and bumps of the flexible circuit board 3 can be identified, the flexible circuit board 3 is prevented from being damaged, and the yield is improved.

[0056] As shown in Figure 3 In the technical scheme of the embodiment, the flexible circuit board bending mechanism 1 further includes a control platform 400, the fixed assembly 100, the bending assembly 200 and the shaping assembly 300 are installed on the same side of the control platform 400 in the first direction Z, wherein the control platform 400 includes a box body 410 and a button 420, control components can be arranged in the box body 410, the control components are connected with the button 420, the bending assembly 200 and the shaping assembly 300 respectively, the movement and reset of the bending assembly 200 and the shaping assembly 300 can be controlled by pressing the button 420, and the automation degree of the flexible circuit board bending mechanism 1 is improved.

[0057] The fixed assembly 100 is provided with the positioning groove 101 on the side away from the control platform 400 in the first direction Z.

[0058] By integrating the fixed assembly 100, the bending assembly 200 and the shaping assembly 300 on the control platform 400, the flexible circuit board bending mechanism 1 can be assembled as a whole, the integration degree of the flexible circuit board bending mechanism 1 is improved, the positioning precision among the fixed assembly 100, the bending assembly 200 and the shaping assembly 300 is increased, the flexible circuit board bending mechanism 1 is convenient to carry and transport, and the application scenarios of the flexible circuit board bending mechanism 1 are improved.

[0059] As shown in Figure 1 , Figure 3 and Figure 4As shown, in the technical solution of this embodiment, there are multiple openings 102, which are spaced apart along the third direction Y. One of the multiple openings 102 is a first opening 102a and the other is a second opening 102b. The first opening 102a is used to extend one end of the flexible circuit board 3, and the second opening 102b is used to extend one end of the flexible circuit board 3.

[0060] There are multiple bending components 200, one of which is a first bending component 201 and the other is a second bending component 202. The first bending component 201 and the second bending component 202 are located on opposite sides of the fixed component 100 along the third direction Y. The first bending component 201 is used to bend one end of the flexible circuit board 3, and the second bending component 202 is used to bend the other end of the flexible circuit board 3.

[0061] In this way, both ends of the flexible circuit board 3 can be bent simultaneously, which improves the bending efficiency of the flexible circuit board bending mechanism 1 on the flexible circuit board 3.

[0062] like Figure 1 and Figure 5 As shown, in the technical solution of this embodiment, the bending assembly 200 includes a roller 243. The roller 243 is connected to one end of the first push rod 220 facing the fixing assembly 100, and the roller 243 is rotatable relative to the first push rod 220. The rotation axis of the roller 243 extends along the first direction Z. The side of the roller 243 facing the fixing assembly 100 extends beyond the end of the first push rod 220 facing the fixing assembly 100. The roller 243 is used to abut against the flexible circuit board 3.

[0063] During the bending process of the flexible circuit board 3 by the roller 243, the flexible circuit board 3 will move relative to the roller 243, and sliding friction will be generated between the flexible circuit board 3 and the roller 243. The roller 243 can convert the sliding friction between the flexible circuit board 3 and the roller 243 into rolling friction by relative to the first push rod 220, thereby reducing the friction force on the flexible circuit board 3, avoiding damage to the flexible circuit board 3 during the bending process, and improving the yield.

[0064] like Figure 5 As shown, in the technical solution of this embodiment, the first push rod 220 includes a first telescopic member 230 and a mounting block 240.

[0065] The first telescopic member 230 includes a first guide post 231 and a first connecting plate 232. The first mounting base 210 is provided with a first guide hole 211 extending in the third direction Y. The first guide post 231 is movably inserted into the first guide hole 211. The first connecting plate 232 is connected to the side of the first guide post 231 facing the fixing assembly 100.

[0066] The mounting block 240 comprises a first mounting plate 241 and a supporting arm 242. The first mounting plate 241 is located on the side of the first connecting plate 232 facing the fixing assembly 100, and the first mounting plate 241 is detachably connected with the first connecting plate 232. The supporting arm 242 is arranged on the side of the first mounting plate 241 facing the fixing assembly 100. One of the supporting arm 242 and the roller 243 is provided with a rotating hole 2421, and the other is provided with a rotating shaft 2431. The rotating shaft 2431 is inserted into the rotating hole 2421, and the rotating shaft 2431 extends along the first direction Z. The roller 243 extends beyond the side of the supporting arm 242 facing the fixing assembly 100.

[0067] By matching the first guide column 231 and the first guide hole 211, the mutual approach or mutual separation of the first connecting plate 232 and the first mounting seat 210 along the third direction Y can be realized, so as to drive the mounting block 240 to drive the roller 243 to contact and separate from the flexible circuit board 3, and the bending of the flexible circuit board 3 can be realized.

[0068] For example, the first mounting seat 210 can be provided with a plurality of first guide holes 211, and the plurality of first guide holes 211 are arranged at intervals along the second direction X. The first stretching and contracting piece 230 comprises a plurality of first guide columns 231, and the plurality of first guide columns 231 are inserted into the plurality of first guide holes 211 one by one. The plurality of first guide columns 231 are connected with the same first connecting plate 232. In this way, the deflection of the first connecting plate 232 relative to the first mounting seat 210 can be avoided, and the smooth movement of the first connecting plate 232 can be ensured.

[0069] By detachably connecting the mounting block 240 with the first connecting plate 232, the mounting block 240 can be replaced without replacing the first stretching and contracting piece 230 and the first mounting seat 210, so as to adjust the relative position between the roller 243 and the flexible circuit board 3, and the flexible circuit board 3 of the battery cell 2 with different sizes or different structures can be bent, and the application range of the bending mechanism 1 is improved.

[0070] Among them, the supporting arm 242 can be at least two, and the two supporting arms 242 are arranged on the opposite sides of the roller 243 along the first direction Z. In this way, the relative position of the roller 243 and the mounting block 240 in the first direction Z can be limited, and the structural stability of the bending assembly 200 is improved.

[0071] In addition, the first mounting plate 241 and the first connecting plate 232 can be connected by a threaded fastener or by a clamping connection. In this way, the disassembly and assembly are relatively convenient, and the contact area between the first mounting plate 241 and the first connecting plate 232 is large, which is conducive to increasing the structural stability of the bending assembly 200.

[0072] Specifically, the first mounting plate 241 comprises a first plate body 2411 and a second plate body 2412, the first plate body 2411 and the second plate body 2412 are connected, the first plate body 2411 and the second plate body 2412 can be integrally formed, the first plate body 2411 is abutted to one side of the first connecting plate 232 away from the control platform 400 along the first direction Z, and the second plate body 2412 is abutted to one side of the first connecting plate 232 toward the fixing assembly 100 along the third direction Y.

[0073] In this way, the positioning of the first mounting plate 241 and the first connecting plate 232 along the first direction Z and the third direction Y can be realized, the assembly of the first push rod 220 is more convenient, the assembly difficulty is reduced, and the production efficiency is improved.

[0074] As shown in Figure 1 and Figure 6 In the technical scheme of the embodiment, the second push rod 320 comprises a second telescopic piece 330 and a pressing block 340.

In this way, the second connecting plate 332 can be prevented from being deflected relative to the second mounting seat 310, and the smooth movement of the second connecting plate 332 can be ensured.

[0079] By detachably connecting the pressing block 340 with the second connecting plate 332, the pressing block 340 can be replaced without replacing the second telescopic piece 330 and the second mounting seat 310, so as to adjust the relative positions between the first pressing arm 350 and the second pressing arm 360 and the flexible circuit board 3, and to realize the sizing of the flexible circuit board 3 of the battery cell 2 with different sizes or different structures, and to improve the application range of the bending mechanism 1.

[0089] In this way, when the battery cell 2 of different sizes and structures is placed in the positioning groove 101, the first elastic member 121, the second elastic member 131, and the third elastic member 141 are compressed to different sizes, the first limiting plate 120 abuts against one end of the battery cell 2 away from the shaping assembly 300 in the second direction X, and the second limiting plate 130 and the third limiting plate 140 abut against one side of the battery cell 2 in the third direction Y, thereby achieving the effect of fixing the battery cell 2.
