Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment, and in particular relates to an automatic bending device for a battery core FPC. Background Art

[0002] FPC is a circuit board made of flexible copper-clad laminate as the substrate, and is used as a medium for signal transmission in the connection of electronic products.

[0003] Connecting the FPC to the upper tabs of the battery cell can monitor the voltage and temperature of the battery cell, connect data collection and transmission, and provide built-in overcurrent protection, as well as protect the battery cell and automatically disconnect in abnormal situations.

[0004] Therefore, in an important link of battery cell production, the two terminal parts of the FPC located at the head of the battery cell need to be bent. Since the distance between the two terminal parts after bending is only about 2 mm, the distance is relatively small. Therefore, the industry has not yet been able to realize automated operations for this bending requirement, and mostly adopts manual bending operations. However, manual bending operations have the problems of low efficiency and low precision. Utility Model Content

[0005] In order to solve the deficiencies of the prior art, the utility model provides an automatic bending device for a battery cell FPC, which realizes the automated bending operation of the FPC double terminals, effectively improves the production efficiency, and performs shaping and visual positioning before bending to ensure the bending accuracy.

[0018] The tightening module comprises a third transverse drive, a parallel cylinder and a tightening assembly, wherein the driving end of the third transverse drive is connected to the parallel cylinder, and the parallel cylinder is connected to the tightening assembly;

[0052] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0053] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0054] Embodiment 1:

[0055] See also Figure 1-Figure 3 A battery cell FPC automatic bending device is used to automatically bend the two terminal parts of FPC B connected to the head of the battery cell A. The two terminal parts of FPC B extend along the width direction of the battery cell. It can be understood that one terminal part is located on the left side of the battery cell head and the other terminal part is located on the right side of the battery cell head. Through the bending device, the two terminal parts are bent toward the middle of the battery cell head.

[0056] The bending equipment includes an FPC shaping mechanism 100 , a first visual inspection mechanism 200 , a second visual inspection mechanism 300 , a first bending mechanism 400 , a second bending mechanism 500 , a head angle closing mechanism 600 and a conveying mechanism 700 .

[0057] It can be understood that the FPC shaping mechanism 100 is used to shape and position the FPC so that the FPC is in a set position to facilitate bending processing; the first visual inspection mechanism 200 is used to collect the position information of the first terminal part of the FPC and feed it back to the first bending mechanism 400, the second visual inspection mechanism 300 is used to collect the position information of the second terminal part of the FPC and feed it back to the second bending mechanism 500, the first bending mechanism 400 adjusts its own position according to the position information of the first terminal part fed back by the first visual inspection mechanism 200, and then bends the first terminal part, the second bending mechanism 500 adjusts its own position according to the position information of the second terminal part fed back by the second visual inspection mechanism 300, and then bends the second terminal part, the head angle closing mechanism 600 is used to tighten the bending angle, and the transporting mechanism 700 transports the battery cells between various mechanisms.

[0058] The FPC shaping mechanism 100, the first bending mechanism 400, the second bending mechanism 500 and the head angle mechanism 600 are distributed in sequence, the conveying mechanism 700 operates between the FPC shaping mechanism 100, the first bending mechanism 400, the second bending mechanism 500 and the head angle mechanism 600, the first visual inspection mechanism 200 is located above the first bending mechanism 400, and the second visual inspection mechanism 300 is located above the second bending mechanism 500.

[0059] This is equivalent to the battery cell being first shaped and positioned by the FPC shaping mechanism 100, and then being transported to the first bending mechanism 400 by the transport mechanism 700 to bend the first terminal part, and then continuing to be transported to the second bending mechanism 500 by the transport mechanism 700 to bend the second terminal part, and finally being transported to the head angle mechanism 600 by the transport mechanism 700 to tighten the bending angle.

[0060] Specifically, the first bending mechanism 400 is used to bend the first terminal part on the FPC toward the middle of the battery cell head to form a first bending angle, and the second bending mechanism 500 is used to bend the second terminal part on the FPC toward the middle of the battery cell head to form a second bending angle. The first bending angle and the second bending angle are respectively located at both ends of the battery cell head, that is, adjacent to the side positions of the battery cell head, and the head angle tightening mechanism 600 is used to tighten the first bending angle and the second bending angle toward the inside of the battery cell head.

[0061] The battery cell FPC automatic bending equipment provided in this embodiment is respectively provided with a first bending mechanism 400 and a second bending mechanism 500 to perform bending operations on the two terminal parts of the FPC, which is suitable for the operation requirements of a small distance between the terminals after bending, realizes automated bending operations, and effectively improves production efficiency; an FPC shaping mechanism 100 is provided to shape the FPC before bending, and a first visual inspection mechanism 200 and a second visual inspection mechanism 300 are provided to perform position detection on the two terminal parts of the FPC before bending, so that the first bending mechanism 400 and the second bending mechanism 500 can perform precise bending operations, effectively ensuring the bending accuracy.

[0062] Embodiment 2:

[0063] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the FPC shaping mechanism 100, the first bending mechanism 400 and the head angle mechanism 600 of the utility model, see Figure 4-Figure 8 .

[0064] See also Figure 4 The FPC shaping mechanism 100 includes a shaping platform 110, a first positioning component 120 and a second positioning component 130. The first positioning component 120 and the second positioning component 130 are respectively located on two adjacent sides of the shaping platform 110, and the positioning directions of the first positioning component 120 and the second positioning component 130 are perpendicular to each other. The first positioning component 120 and the second positioning component 130 are respectively arranged to shape the front, back, left and right sides of the FPC to improve the bending accuracy of the FPC.

[0065] For example, the first positioning component 120 is used to shape and position the FPC in the X-axis direction, and the second positioning component 130 is used to shape and position the FPC in the Y-axis direction. After the battery cell is placed on the shaping platform 110, the FPC is positioned in two directions respectively by the first positioning component 120 and the second positioning component 130, and then the battery cell is transported to the first bending mechanism 400 for bending operation via the transport mechanism 700.

[0066] Specifically, the first positioning component 120 may include a first positioning driver and a first positioning reference block, and the first positioning driver and the first positioning reference block are respectively located on opposite sides of the shaping platform 110. Similarly, the second positioning component 130 may include a second positioning driver and a second positioning reference block, and the second positioning driver and the second positioning reference block are respectively located on opposite sides of the shaping platform 110. The first positioning driver is used to push the FPC to abut against the first positioning reference block in the X-axis direction, and the second positioning driver is used to push the FPC to abut against the second positioning reference block in the Y-axis direction, so as to achieve the effect of shaping and positioning the FPC.

[0067] See also Figure 5 and Figure 6 In some embodiments, the first bending mechanism 400 includes a clamping and bending module 410 and a pressing module 420. The pressing module 420 is located above the clamping and bending module 410. The clamping and bending module 410 is used to clamp the terminal part to drive the terminal part to bend, and the pressing module 420 is used to press the bending part to make the FPC plastically deformed.

[0068] The clamping and bending module 410 includes a clamping jaw assembly 411 and a position adjustment assembly 412. The clamping jaw assembly 411 is connected to the driving end of the position adjustment assembly 412. The position adjustment assembly 412 drives the clamping jaw assembly 411 to correct the deviation according to the position information of the first terminal part fed back by the first visual inspection mechanism 200, and then accurately clamps the first terminal part.

[0069] The pressing module 420 includes a pressing block 421 and a first lifting drive assembly 422 . The pressing block 421 is connected to the driving end of the first lifting drive assembly 422 . The pressing block 421 presses down the FPC at the bent portion or lifts it up under the action of the first lifting drive assembly 422 .

[0070] During application, after the battery cell is transported to the position of the first bending mechanism 400 by the transport mechanism 700, the first visual inspection mechanism 200 located above the first bending mechanism 400 collects the position information of the first terminal part and feeds it back to the position adjustment component 412. The position adjustment component 412 drives the clamping jaw component 411 to correct the deviation according to the position information of the first terminal part fed back by the first visual inspection mechanism 200, and then accurately clamps the first terminal part to drive the terminal part to bend. After the bending operation, the first lifting drive component 422 drives the pressing block 421 to press down the FPC of the bent part, so that the FPC is plastically deformed to ensure that it is bent in place.

[0071] In some embodiments, the position adjustment assembly 412 includes a first transverse drive 4121, a second transverse drive 4122 and a first rotation drive 4123, the driving end of the first transverse drive 4121 is connected to the second transverse drive 4122, the driving end of the second transverse drive 4122 is connected to the first rotation drive 4123, and the driving end of the first rotation drive 4123 is connected to the clamping jaw assembly 411; the driving directions of the first transverse drive 4121 and the second transverse drive 4122 are perpendicular to each other, for example, the first transverse drive 4121 is used to drive the clamping jaw assembly 411 to move in the X-axis direction, and the second transverse drive 4122 is used to drive the clamping jaw assembly 411 to move in the Y-axis direction, and then cooperate with the first rotation drive 4123 to adjust the position of the clamping jaw assembly 411 in multiple directions to accurately clamp the first terminal part to ensure bending accuracy.

[0072] Similarly, the structure and operation process of the second bending mechanism 500 are the same as those of the first bending mechanism 400. After the operation of the first bending mechanism 400 is completed, the transporting mechanism 700 transports the battery cell to the position of the second bending mechanism 500, and the second terminal part on the FPC is bent by the second bending mechanism 500, thereby realizing automatic and high-precision bending operation of the battery cell FPC.

[0073] See also Figure 7 and Figure 8 In some embodiments, the head angle mechanism 600 includes a clamping module 610 and a tightening module 620. The clamping module 610 is located above the tightening module 620. The surface of the battery cell is first clamped by the clamping module 610, and then the two bending angles are tightened by the tightening module 620.

[0074] The pressing module 610 includes a pressing block 611 and a second lifting drive assembly 612 . The pressing block 611 is connected to the driving end of the second lifting drive assembly 612 . The pressing block 611 is used to press the battery cell.

[0075] The tightening module 620 includes a third transverse drive 621, a parallel cylinder 622 and a tightening assembly 623. The driving end of the third transverse drive 621 is connected to the parallel cylinder 622, and the parallel cylinder 622 is connected to the tightening assembly 623. The third transverse drive 621 drives from the tail to the head of the battery cell, so that the tightening module 620 moves along this direction until it is located at the head position of the battery cell, thereby tightening the first bending angle and the second bending angle.

[0076] When in use, the second lifting drive assembly 612 first drives the clamping block 611 to clamp the surface of the battery cell, and then the third transverse drive 621 drives the tightening module 620 to drive along the direction from the tail to the head of the battery cell. At the same time, the parallel cylinder 622 of the tightening module 620 drives the tightening assembly 623 to clamp both sides of the battery cell until the tightening assembly 623 moves to the head position of the battery cell, and then tightens the two bending corners at both ends of the head position of the battery cell toward the middle direction of the head of the battery cell, that is, completing the tightening head angle operation.

[0077] Specifically, the tightening assembly 623 includes a first tightening unit 623a and a second tightening unit 623b that are relatively arranged; the first tightening unit 623a includes a first mounting seat 6231, a first elastic member 6232, a first mounting block 6233 and a first rolling member 6234, the first rolling member 6234 is installed on the first mounting block 6233, the two ends of the first elastic member 6232 are respectively connected to the first mounting seat 6231 and the first mounting block 6233, the first mounting seat 6231 is connected to the driving end of the parallel cylinder 622, and the first elastic member 6232 is arranged to cooperate with the first rolling member 6234, which can ensure that the contact between the first tightening unit 623a and the battery cell and the first bending angle is elastic contact, thereby avoiding hard force collision to damage the battery cell or FPC.

[0078] The first tightening unit 623a and the second tightening unit 623b are both connected to the driving end of the parallel cylinder 622. Under the driving action of the parallel cylinder 622, the first tightening unit 623a and the second tightening unit 623b are opened or closed in a parallel manner. When the first tightening unit 623a and the second tightening unit 623b are closed under the driving action of the parallel cylinder 622, the first rolling member 6234 is used to make rolling contact with the side of the battery cell under the driving action of the third transverse drive 621, and is used to be elastically contacted with the battery cell and the bending angle under the driving action of the parallel cylinder 622 under the elastic action of the first elastic member 6232, so as to avoid damaging the battery cell or FPC.

[0079] It can be known that the structure and operation principle of the second tightening unit 623b are the same as those of the first tightening unit 623a, so it can be understood by referring to the first tightening unit 623a.

[0080] Embodiment 3:

[0081] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the bending device of the utility model, see Fig. 9 .

[0082] The bending equipment also includes a material unloading transfer mechanism 800, which is arranged adjacent to the head angle mechanism 600; the transport mechanism 700 includes a fourth transverse movement driver 710 and four lifting and placing modules 720, and the fourth transverse movement driver 710 synchronously drives the four lifting and placing modules 720, so that the four lifting and placing modules 720 respectively correspond to the positions of the FPC shaping mechanism 100, the first bending mechanism 400, the second bending mechanism 500 and the head angle mechanism 600, or respectively correspond to the positions of the first bending mechanism 400, the second bending mechanism 500, the head angle mechanism 600 and the material unloading transfer mechanism 800, so as to achieve the effect of synchronous material picking, material placing and synchronous operation of each mechanism, realize fully automated operation and effectively improve operation efficiency.

[0083] For example, during one operation, the fourth transverse movement driver 710 drives four lifting and placing modules 720, which correspond to the FPC shaping mechanism 100, the first bending mechanism 400, the second bending mechanism 500 and the head angle mechanism 600 respectively. The four lifting and placing modules 720 take away the battery cells on each mechanism respectively. Then, the fourth transverse movement driver 710 drives the four lifting and placing modules 720 again, which correspond to the first bending mechanism 400, the second bending mechanism 500, the head angle mechanism 600 and the unloading transfer mechanism 800 respectively, and places the battery cells on each mechanism accordingly, thereby achieving the effect of synchronous material picking, material placing and synchronous operation of each mechanism.

[0084] The lifting and placing module 720 may include a lifting drive and a suction plate connected to the lifting drive. After the suction plate is moved downward to the surface of the battery cell by the lifting drive, the battery cell is adsorbed by the suction plate to achieve an automatic material picking effect; similarly, when discharging the material, the suction plate is moved downward to the surface of the battery cell by the lifting drive, and the battery cell is released to achieve an automatic material discharging effect.

[0085] Embodiment 4:

[0086] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the bending device of the utility model, see Fig.10 and Fig.11 .

[0087] There are two FPC shaping mechanisms 100, first visual inspection mechanisms 200, second visual inspection mechanisms 300, first bending mechanisms 400, second bending mechanisms 500, head angle mechanisms 600 and conveying mechanisms 700, and each mechanism is symmetrically distributed in pairs to realize a dual-channel operation mode, thereby effectively improving the operation efficiency.

[0088] In some embodiments, a loading mechanism 900 is further included. The loading mechanism 900 operates between two FPC shaping mechanisms 100 and is used to load two battery cells to the two FPC shaping mechanisms 100 respectively.

[0089] The loading mechanism 900 includes a fifth transverse driving device 910 and a loading module 920. The loading module 920 is connected to the driving end of the fifth transverse driving device 910 to automatically load the battery cells to achieve an automated operation effect.

[0090] Specifically, the loading module 920 includes a third lifting drive component 921, a second rotary driver 922 and a double-station pick-and-place component 923. The driving end of the third lifting drive component 921 is connected to the second rotary driver 922, and the driving end of the second rotary driver 922 is connected to the double-station pick-and-place component 923, ensuring that the loading direction of the battery cell meets the dual-channel operation requirements.

[0091] The double-station pick-and-place component 923 can pick up and place two battery cells at the same time. For example, when the loading module 920 moves to one of the FPC shaping mechanism 100 positions under the driving action of the fifth transverse drive 910, the third lifting drive component 921 drives the double-station pick-and-place component 923 to move downward, places one of the battery cells at the position of the FPC shaping mechanism 100, and the third lifting drive component 921 is reset; then, the loading module 920 continues to move to another FPC shaping mechanism 100 position under the driving action of the fifth transverse drive 910.
