For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] Combine the following Figures 1 to 8 , describing an embodiment of the present invention.

[0051] According to an embodiment of the present invention, on the one hand, a flexible circuit board bending mechanism 1 is provided, the flexible circuit board bending mechanism 1 has a first direction Z, a second direction X and a third direction Y that intersect each other, and the flexible circuit board bending mechanism 1 includes a fixing component 100, a bending component 200 and a shaping component 300.

[0052] The fixing assembly 100 is provided with a positioning groove 101 on one side along the first direction Z, and an opening 102 is provided on the groove wall of the positioning groove 101 in the second direction X. The positioning groove 101 is used to place the battery cell 2 with the flexible circuit board 3, and the opening 102 is used to extend the flexible circuit board 3. The bending assembly 200 includes a first mounting seat 210 and a first push rod 220. The first mounting seat 210 and the fixing assembly 100 are arranged along the third direction Y. The first push rod 220 is connected to the side of the first mounting seat 210 facing the fixing assembly 100. The first push rod 220 is movable along the third direction Y for bending the flexible circuit board 3. The shaping assembly 300 includes 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. The second push rod 320 is movable along the second direction X for pressing the bent flexible circuit board 3.

[0053] Wherein, the first mounting seat 210 and the second mounting seat 310 may both include a cylinder, which drives the first push rod 220 and the second push rod 320 to move by air pressure; or, the first mounting seat 210 and the second mounting seat 310 may both include a motor, which drives the first push rod 220 and the second push rod 320 to move by the motor.

[0054] After the battery cell 2 with the flexible circuit board 3 is installed in the positioning groove 101, a part of the flexible circuit board 3 is extended from the opening 102, and then the first push rod 220 is controlled to move relative to the first mounting seat 210, and the first push rod 220 gradually approaches the fixing component 100 and contacts the part of the flexible circuit board 3 extending from the opening 102, driving the flexible circuit board 3 to start bending. After the flexible circuit board 3 is bent into place, the first push rod 220 is reset and moves away from the fixing component 100. Next, the second push rod 320 is controlled to move relative to the second mounting seat 310, and the second push rod 320 gradually approaches the fixing component 100 and contacts the part of the flexible circuit board 3 extending from the opening 102, driving the flexible circuit board 3 to remain in the bent state. Finally, the second push rod 320 is reset and moves away from the fixing component 100, completing the bending of the flexible circuit board 3.

[0055] The flexible circuit board bending mechanism 1 of the embodiment of the present invention can not only bend and press the flexible circuit board 3 to shape, but also has a simple structure, low design cost, and is open on all sides, which is convenient for observing the product process status. It can identify whether the flexible circuit board 3 has risks such as scratches and bumps, avoid damage to the flexible circuit board 3, and improve the yield rate.

[0056] like Figure 3 As shown, in the technical solution of this embodiment, the flexible circuit board bending mechanism 1 also includes a control platform 400, and the fixing component 100, the bending component 200 and the shaping component 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, and control components may be provided in the box body 410, and the control components are respectively connected to the button 420, the bending component 200 and the shaping component 300. By pressing the button 420, the movement and reset of the bending component 200 and the shaping component 300 can be controlled, thereby improving the degree of automation of the flexible circuit board bending mechanism 1.

[0057] A positioning groove 101 is provided on a side of the fixing component 100 facing away from the control platform 400 in the first direction Z.

[0058] By integrating the fixing component 100, the bending component 200 and the shaping component 300 into the control platform 400, the flexible circuit board bending mechanism 1 can be assembled into a whole, thereby improving the degree of integration of the flexible circuit board bending mechanism 1, increasing the positioning accuracy among the fixing component 100, the bending component 200 and the shaping component 300, and the flexible circuit board bending mechanism 1 is easy to carry and transport, which can improve the applicable scenarios of the flexible circuit board bending mechanism 1.

[0059] like Figure 1 , Figure 3 and Figure 4As shown, in the technical solution of this embodiment, there are multiple openings 102, and the multiple openings 102 are arranged at intervals 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 the multiple bending components 200 is the first bending component 201 and the other is the 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 at the same time, thereby improving the bending efficiency of the flexible circuit board 3 by the flexible circuit board bending mechanism 1 .

[0062] like Figure 1 and Figure 5 As shown, in the technical solution of this embodiment, the bending component 200 includes a roller 243, which is connected to one end of the first push rod 220 toward the fixed component 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 toward the fixed component 100 exceeds the end of the first push rod 220 toward the fixed component 100, and the roller 243 is used to stop with the flexible circuit board 3.

[0063] During the process of the roller 243 bending the flexible circuit board 3, 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 moving 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 rate.

[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 column 231 and a first connecting plate 232. The first mounting seat 210 is provided with a first guide hole 211 extending along the third direction Y. The first guide column 231 is movably inserted in the first guide hole 211. The first connecting plate 232 is connected to the side of the first guide column 231 facing the fixed component 100.

[0066] The mounting block 240 includes a first mounting plate 241 and a support arm 242. The first mounting plate 241 is located on the side of the first connecting plate 232 facing the fixed component 100, and the first mounting plate 241 is detachably connected to the first connecting plate 232. The support arm 242 is arranged on the side of the first mounting plate 241 facing the fixed component 100. One of the support 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. The rotating shaft 2431 extends along the first direction Z, and the roller 243 extends beyond the side of the support arm 242 facing the fixed component 100.

[0067] By setting the first guide column 231 and the first guide hole 211 in cooperation, the first connecting plate 232 and the first mounting seat 210 can be moved closer to or farther away from each other along the third direction Y, thereby driving the mounting block 240 to drive the roller 243 to contact and separate from the flexible circuit board 3, thereby realizing bending of the flexible circuit board 3.

[0068] For example, the first mounting seat 210 may be provided with a plurality of first guide holes 211, the plurality of first guide holes 211 are arranged at intervals along the second direction X, the first telescopic member 230 includes a plurality of first guide posts 231, the plurality of first guide posts 231 are inserted into the plurality of first guide holes 211 one by one, and the plurality of first guide posts 231 are connected to the same first connecting plate 232. In this way, the first connecting plate 232 can be prevented from deflecting relative to the first mounting seat 210, which is conducive to ensuring the smooth movement of the first connecting plate 232.

[0069] By providing the mounting block 240 to be detachably connected to the first connecting plate 232, the mounting block 240 can be replaced without replacing the first telescopic member 230 and the first mounting seat 210 to adjust the relative position between the roller 243 and the flexible circuit board 3, thereby achieving bending of the flexible circuit board 3 of the battery cells 2 of different sizes or structures, thereby improving the application scope of the bending mechanism 1.

[0070] There may be at least two support arms 242 , and the two support arms 242 are arranged on opposite sides of the roller 243 along the first direction Z, so as to limit the relative positions of the roller 243 and the mounting block 240 in the first direction Z and improve the structural stability of the bending assembly 200 .

[0071] In addition, the first mounting plate 241 and the first connecting plate 232 can be connected by threaded fasteners or by snap-fitting, which makes disassembly and assembly more convenient, and the contact area between the first mounting plate 241 and the first connecting plate 232 is large, which is beneficial to increasing the structural stability of the bending assembly 200.

[0072] Specifically, the first mounting plate 241 includes a first plate body 2411 and a second plate body 2412, and 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 stops at the side of the first connecting plate 232 facing away from the control platform 400 along the first direction Z, and the second plate body 2412 stops at the side of the first connecting plate 232 facing the fixed component 100 along the third direction Y.

[0073] In this way, the first mounting plate 241 and the first connecting plate 232 can be positioned in the first direction Z and the third direction Y, and the assembly of the first push rod 220 is more convenient, which reduces the difficulty of assembly and improves production efficiency.

[0074] like Figure 1 and Figure 6 As shown, in the technical solution of this embodiment, the second push rod 320 includes a second telescopic member 330 and a pressing block 340 .

[0075] The second telescopic member 330 includes a second guide column 331 and a second connecting plate 332. The second mounting seat 310 is provided with a second guide hole 311 extending along the second direction X. The second guide column 331 is movably inserted in the second guide hole 311. The second connecting plate 332 is connected to the side of the second guide column 331 facing the fixing assembly 100.

[0076] The pressing block 340 includes a second mounting plate 341, a first pressing arm 350 and a second pressing arm 360. The second mounting plate 341 is located on the side of the second connecting plate 332 facing the fixing component 100, and the second mounting plate 341 is detachably connected to the second connecting plate 332. The first pressing arm 350 and the second pressing arm 360 are arranged on the side of the second mounting plate 341 facing the fixing component 100. The first pressing arm 350 and the second pressing arm 360 are spaced apart along the third direction Y. The first pressing arm 350 presses one end of the bent flexible circuit board 3, and the second pressing arm 360 presses the other end of the bent flexible circuit board 3.

[0077] By setting the second guide column 331 and the second guide hole 311 in cooperation, the second connecting plate 332 and the second mounting seat 310 can be moved closer to or farther away from each other along the second direction X, thereby driving the pressing block 340 to drive the first pressing arm 350 and the second pressing arm 360 to contact and separate from the flexible circuit board 3, thereby achieving the shaping of the flexible circuit board 3.

[0078] For example, the second mounting seat 310 may be provided with a plurality of second guide holes 311, the plurality of second guide holes 311 are arranged at intervals along the third direction Y, the second telescopic member 330 includes a plurality of second guide posts 331, the plurality of second guide posts 331 are inserted into the plurality of second guide holes 311 one by one, and the plurality of second guide posts 331 are connected to the same second connecting plate 332. In this way, the second connecting plate 332 can be prevented from deflecting relative to the second mounting seat 310, which is conducive to ensuring the smooth movement of the second connecting plate 332.

[0079] By arranging the pressing block 340 to be detachably connected to the second connecting plate 332, the pressing block 340 can be replaced without replacing the second telescopic member 330 and the second mounting seat 310 to adjust the relative positions between the first pressing arm 350 and the second pressing arm 360 and the flexible circuit board 3, thereby achieving shaping of the flexible circuit board 3 of the battery cells 2 of different sizes or structures, thereby improving the applicability of the bending mechanism 1.

[0080] In addition, the second mounting plate 341 and the second connecting plate 332 can be connected by threaded fasteners or by snap-fitting, which makes disassembly and assembly more convenient, and the contact area between the second mounting plate 341 and the second connecting plate 332 is large, which is beneficial to increasing the structural stability of the bending assembly 200.

[0081] Specifically, the second mounting plate 341 includes a third plate body 3411 and a fourth plate body 3412. The third plate body 3411 and the fourth plate body 3412 are connected. The third plate body 3411 and the fourth plate body 3412 can be integrally formed. The third plate body 3411 stops at the side of the second connecting plate 332 facing away from the control platform 400 along the first direction Z, and the fourth plate body 3412 stops at the side of the second connecting plate 332 facing the fixing component 100 along the second direction X.

[0082] In this way, the second mounting plate 341 and the second connecting plate 332 can be positioned in the first direction Z and the second direction X, and the assembly of the second push rod 320 is more convenient, which reduces the assembly difficulty and improves the production efficiency.

[0083] Furthermore, if Figure 4 As shown, a protrusion 111 is provided on the side of the fixing component 100 facing the shaping component 300, and the protrusion 111 is located between the first pressing arm 350 and the second pressing arm 360 in the third direction Y. The protrusion 111, the first pressing arm 350 and the second pressing arm 360 can play a guiding role, which is beneficial to ensure the pressing accuracy of the first pressing arm 350 and the second pressing arm 360.

[0084] The size of the protrusion 111 in the second direction X can be gradually reduced toward the direction close to the shaping assembly 300, thereby serving as a guide to avoid interference between the protrusion 111, the first pressing arm 350 and the second pressing arm 360. In addition, the protrusion 111 can be provided with a notch 112 to reduce material usage, cost and weight.

[0085] like Figure 1 and Figure 4 As shown, in the technical solution of this embodiment, the fixing assembly 100 includes a base 110, a first limiting plate 120, a second limiting plate 130, a third limiting plate 140, a first elastic member 121, a first guide rod 122, a second elastic member 131, a second guide rod 132, a third elastic member 141 and a third guide rod 142.

[0087] The first limiting plate 120 is connected to the first guide rod 122, which is movably inserted in the first through hole 123. A first elastic member 121 is provided between the first limiting plate 120 and a side wall of the positioning groove 101 away from the shaping assembly 300 in the second direction X. The second limiting plate 130 is connected to the second guide rod 132, which is movably inserted in the second through hole 133. A second elastic member 131 is provided between the second limiting plate 130 and a side wall in the third direction Y. The third limiting plate 140 is connected to the third guide rod 142, which is movably inserted in the third through hole 143. A third elastic member 141 is provided between the third limiting plate 140 and a side wall in the third direction Y.

[0088] The first elastic member 121 , the second elastic member 131 and the third elastic member 141 can all be springs. The first elastic member 121 is sleeved on the first guide rod 122 , the second elastic member 131 is sleeved on the second guide rod 132 , and the third elastic member 141 is sleeved on the third guide rod 142 .

[0089] In this way, when the battery cells 2 of different sizes and structures are 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 stops at one end of the battery cell 2 in the second direction X away from the shaping component 300, and the second limiting plate 130 and the third limiting plate 140 stop at one side of the battery cell 2 in the third direction Y, thereby fixing the battery cell 2. The fixing component 100 can fix battery cells 2 of different styles, which improves the application scope of the fixing component 100, saves the design cost and manufacturing cost of the fixing component 100, and does not need to replace the fixing component 100, thereby improving the efficiency of bending the flexible circuit board 3 and thus improving the production capacity.

[0090] Furthermore, the bottom of the positioning groove 101 is provided with a first limiting groove 103, a second limiting groove 104 and a third limiting groove 105, a portion of the first limiting plate 120 is located in the first limiting groove 103, a portion of the second limiting plate 130 is located in the second limiting groove 104, and a portion of the third limiting plate 140 is located in the third limiting groove 105.

[0091] By setting the first limiting groove 103, the second limiting groove 104 and the third limiting groove 105, the installation positions of the first limiting plate 120, the second limiting plate 130 and the third limiting plate 140 can be limited, and the movement ranges of the first limiting plate 120, the second limiting plate 130 and the third limiting plate 140 can be limited.

[0093] The battery cell 2 is usually connected to a printed circuit board (PCB) 4 and a flexible circuit board 3. The flexible circuit board 3 is connected to the printed circuit board 4. Since the flexible circuit board 3 has a low hardness and is prone to deformation, it needs to be supported and limited by hard parts. The position of the flexible circuit board 3 on one side in the third direction Y can be limited by the printed circuit board 4. The other side of the flexible circuit board 3 in the third direction Y is located in the positioning gap 170 and is limited by the first clamp 150 and the second clamp 160.

[0094] When the flexible circuit board 3 is bent, one end of the flexible circuit board 3 is bent along the printed circuit board 4, and the other end of the flexible circuit board 3 is bent along the first clamping block 150;

[0095] After the flexible circuit board 3 is bent, the first pressing arm 350 presses the first part 31 of the flexible circuit board 3 to the side of the printed circuit board 4 facing away from the battery cell 2 in the second direction X, and the second pressing arm 360 presses the second part 32 of the flexible circuit board 3 to the side of the first clamp 150 facing away from the battery cell 2 in the second direction X.

[0096] In this way, deformation of the flexible circuit board 3 can be avoided, the bending accuracy can be improved, and the pressing and shaping effect can be optimized.

[0097] Further, the first clamping block 150 includes a first bottom plate 151 and a first clamping plate 152, the first bottom plate 151 is disposed in the groove 106, the first clamping plate 152 is connected to the side of the first bottom plate 151 facing away from the base 110 along the first direction Z, and a mounting groove 153 is provided on the side of the first bottom plate 151 facing away from the base 110 along the first direction Z. The second clamping block 160 includes a second bottom plate 161 and a second clamping plate 162, the second bottom plate 161 is disposed in the mounting groove 153, and the second clamping plate 162 is connected to the side of the second bottom plate 161 facing away from the base 110 along the first direction Z.
