[0052] See also Figure 2-5The present invention provides a flexible connection production line, comprising an unwinding mechanism 1, a pressing mechanism 2, a welding machine 3, a bending machine 4 and / or a cutting and punching mechanism 5 which are arranged in sequence;

[0053] The unwinding mechanism 1 includes a plurality of unwinding wheels 11, each of which is driven to rotate by an independent driving mechanism to unwind the corresponding foil strip 10; the pressing mechanism 2 includes at least two pressing wheels 21, and the pressing mechanism 2 is configured to collect and stack the plurality of foil strips 10 conveyed between the two pressing wheels 21 into a foil strip group 20; the welding machine 3 is configured to weld and connect the conveyed foil strip group 20 at a preset position; the bending machine 4 is configured to bend the conveyed foil strip group 20 at a preset length position; and / or the cutting and punching mechanism 5 is configured to cut the conveyed foil strip group 20 according to a preset length.

[0054] It should be noted that the foil strip 10 is a nickel strip and / or a copper strip and / or an aluminum strip and / or a steel strip and / or other foil strips 10 that meet the use requirements, but the outermost foil strip 10 can at least be welded by the welder 3. The unwinding mechanism 1, the pressing mechanism 2, the welder 3, the bending machine 4 and / or the cutting and punching mechanism 5 can be fixed to the ground in sequence, or a frame can be set so that the unwinding mechanism 1, the pressing mechanism 2, the welder 3, the bending machine 4 and / or the cutting and punching mechanism 5 are installed on the same frame. The pressing mechanism 2, the welder 3, the bending machine 4 and / or the cutting and punching mechanism 5 can be sequentially passed through and conveyed by the foil strip 10 unwound by the unwinding mechanism 1. The unwinding mechanism 1, the pressing mechanism 2, the welding machine 3, the bending machine 4, the punching mechanism 5 and other arranged mechanisms all have their own corresponding frames; generally, the unwinding mechanism 1, the pressing mechanism 2, the welding machine 3, the bending machine 4, the punching mechanism 5 and other arranged mechanisms are arranged in a straight line direction, so that the flexible connection is transported and processed in a straight line direction. It should be understood that the flexible connection production line also includes some sensors and control elements and / or control systems, so that the unwinding mechanism 1, the pressing mechanism 2, the welding machine 3, the bending machine 4, the punching mechanism 5 and other arranged mechanisms can work in coordination. The unwinding mechanism 1 has at least two unwinding wheels 11, for example, two, four, six or nine can be set, and all the unwinding wheels 11 are generally arranged up and down, axially parallel and aligned, so that the foil strip 10 unwound by the unwinding wheel 11 is aligned in the width direction. The unwinding wheel 11 is wound with a foil strip 10, and the unwinding wheel 11 is driven by an independent driving mechanism, and the unwinding wheel 11 is in transmission connection with the driving mechanism, and the driving mechanism can be a private motor, a stepping motor, an AC motor, or other driving mechanisms that meet the use requirements, and each of the driving mechanisms drives the corresponding unwinding wheel 11 at a rotation rate according to the adjustment increment of the corresponding foil strip 10. The unwinding mechanism 1 can unwind, gather, and stack the foil strip 10 into multiple layers of foil strip 10. The pressing mechanism 2 comprises at least two pressing wheels 21, which are arranged in parallel and opposite to each other, and the two pressing wheels 21 form a group. The pressing mechanism 2 can be provided with multiple groups of pressing wheels 21 according to the use requirements. The two pressing wheels 21 are distributed up and down along the conveying direction of the foil strip 10, and there is a gap between the two pressing wheels 21, so that multiple foil strips 10 can pass through the gap, so that multiple foil strip groups 20 can be gathered together; the size of the gap is adjustable and used to adjust the gap between each foil strip 10, that is, the foil strip 10 can be pressed or compressed by adjusting the gap between the upper and lower pressing wheels 21, and the smaller gap can make the collected multiple foil strips 10 overlap along the thickness direction of the foil strip group 20, so that multiple foil strip groups 20 can overlap to form a foil strip group 20, and the pressing wheel 21 can be selected according to actual needs. Whether it can be actively driven to rotate, the rotating shaft of the pressing wheel 21 can be rotatably connected to the end of the vertically arranged electric telescopic rod or cylinder rod to realize the movement of each pressing wheel 21 in the up and down direction to adjust the gap.The welding machine 3 is generally a polymer diffusion welding machine, which presses up and down through a punch, and uses graphene to melt at high temperature so that the foil strip group 20 with multiple layers of foil strips 10 is welded together. It should be understood that a welding machine 3 that meets the use requirements, such as an energy storage spot welding machine, a medium frequency inverter DC spot projection welding machine, etc., can also be used. The bending machine 4 can be a bending machine 4 that meets the use requirements, such as a CNC bending machine, a hydraulic bending machine, a special bending machine, etc. The cutting and punching mechanism 5 is a punching machine or a shearing machine or a punching and cutting die. For example, the cutting and punching mechanism 5 can punch holes and trim the foil strip group 20.

[0055] It should be understood that the soft connection production line in this case realizes automatic control by connecting control elements such as PLC, which can make the soft connection production line in this case a precise automated equipment.

[0056] In this case, the non-incremental soft connection 40 can be in a straight state before and after welding. It is necessary to set the step length of the foil 10 in advance according to the process route. The step length is the unfolded length of the soft connection 40, that is, the length when the foil group 20 is cut to form the soft connection 40. The pressing mechanism 2 presses at the predetermined position, the welding machine 3 welds at the predetermined position, and the cutting and punching mechanism 5 cuts at the predetermined position. Generally, they are preset according to the step length. Of course, there can be other special cases, which can be preset according to actual needs. In this case, the total thickness of the multiple foil strips 10 unwound by the unwinding mechanism 1 is the thickness of the soft connection 40 / the thickness of the sheet; and then the multiple foil strips 10 are integrated into the state before welding through the pressing wheel 21, wherein the thickness direction is perpendicular to the conveying direction of the foil strip 10.

[0057] It should be noted that the flexible connection 40 has various shapes. The structure of the flexible connection 40 is similar to a race track, with a short inner line and a long outer line. However, in an "S"-shaped race track, the inner and outer sides are of equal length. The length of the copper foil of the last layer of the copper bar is an increment of the copper bar relative to the length of the first layer of copper foil. Figure 1 , the increment size is sorted as: M4<M1<M2<M3; even if the copper bar is very long, as long as the difference between the number of bends in the same direction and the number of bends in the opposite direction is zero, the increment of the copper bar can be ignored!

[0058] The flexible connection production line provided in this case can at least realize the continuous automatic unloading, welding, bending and punching processes of the foil strip 10, realize the continuous automatic production of the foil strip 10, reduce the process transfer cycle when each process is produced separately, thereby effectively improving production efficiency and reducing manual labor intensity, number of workers and labor costs; this case replaces the manual control increment and improves the production accuracy of the flexible connection 40.

[0059] See also Figure 2-3 , as an optional embodiment of the present case, the bending machine 4 includes a bending fixture 41 and a driving member 42;

[0060] The bending fixture 41 is configured to be able to clamp a certain section of the foil strip set 20 in the length direction;

[0061] The driving member 42 is in transmission connection with the bending fixture 41, and the driving member 42 is configured to drive the bending fixture 41 to move forward and / or reversely according to the preset length increment of each foil strip 10 in the foil strip group 20, so as to bend the foil strip group 20 into a predetermined deflection angle.

[0062] It should be noted that the driving member 42 is a private service motor or a stepping motor or an AC motor or other driving member 42 that meets the use requirements; the bending fixture 41 can allow the foil tape group 20 to pass through, that is, a section of the foil tape group 20 is located in the bending fixture 41, and the driving member 42 can drive the bending fixture 41 to move forward and / or reverse according to the preset length increment of each foil tape 10 in the foil tape group 20 to bend the foil tape group 20 into a predetermined deflection angle, that is, after the bending fixture 41 bends the foil tape group 20, the bending point of the foil tape group 20 is close to the nearest welding area 31 or the foil tapes 10 in the area between the welding points are in a tensioned state, rather than a certain foil tape 10 being too long and in a loose state. In this case, the driving member 42 drives the bending fixture 41 to rotate forward or reversely, so that the foil strip group 20 has at least one bending point, and may also have multiple bending points. When the foil strip group 20 has multiple bending points, the multiple bending points may face opposite directions, that is, the driving member 42 drives the bending fixture 41 to rotate forward to enable the foil strip group 20 to have a positive bending point, and the driving member 42 drives the bending fixture 41 to rotate reversely to enable the foil strip group 20 to have a reverse bending point. In this case, the driving member 42 drives the bending fixture 41 to rotate to bend the foil strip group 20, which is not only simple in structure, but also convenient and efficient in bending the foil strip group 20 forward and reverse.

[0063] See also Figure 2-3 , as an optional embodiment of the present case, the bending fixture 41 includes a connecting member 411 and at least two clamping plates 412;

[0064] The connecting member 411 is drivingly connected to the driving member 42 ; at least two clamping plates 412 are connected to the connecting member 411 , and a first gap 413 is defined between the two clamping plates 412 for the foil tape set 20 to pass through.

[0065] It should be noted that the connecting member 411 can be a circular plate or a square plate, and the connecting member 411 and each clamping plate 412 are connected by welding or detachably connected by fasteners, or the spacing between each clamping plate 412 is adjustable on the connecting member 411. The end face of at least one end of each clamping plate 412 in the length direction is a plane or an inclined surface, and the end of each clamping plate 412 in the length direction is the position of the folding point on the forming foil strip group 20. When the end face of the clamping plate 412 in the length direction is an inclined surface, an oblique bending point can be folded out. The two clamping plates 412 are arranged at an angle or in parallel, and both ends of the two clamping plates 412 along the length direction have gaps, and the minimum gap is the first gap 413. The first gap 413 can allow the foil strip group 20 to pass through, and the end of each clamping plate 412 in the length direction is an arc end or a flat tip, so as to facilitate bending out different bending points according to actual needs.

[0066] See also Figure 2-3 As an optional embodiment of the present case, the pressing mechanism 2, the welding machine 3, the bending machine 4 and / or the cutting and punching mechanism 5 are generally arranged along a straight line, so that the foil strip group 20 can be processed and formed along a straight line.

[0067] See also Figure 2-3 As an optional embodiment of the present invention, a guide mechanism 7 is provided between the welding machine 3 and the bending machine 4. The guide mechanism 7 is at least one pair of guide wheels 71 or at least one pair of guide plates. The guide mechanism 7 is used to ensure that the foil strip group 20 is transported in a predetermined direction and to assist the bending machine 4 of the present invention in bending the foil strip group 20.

[0068] See also Figure 2 As an optional embodiment of the present case, an oxidation grinder 6 is arranged between the welding machine 3 and the cutting and punching mechanism 5, and the oxidation grinder 6 is configured to grind the surface of the delivered foil tape group 20.

[0069] It should be noted that the oxidation grinder 6 includes two upper and lower grinding discs, and the two grinding discs are used to grind the welding parts of the foil tape set 20 to make the surface of the foil tape set 20 smooth and neat.

[0070] As an optional embodiment of the present case, a cleaning and drying machine is provided between the oxidation grinder 6 and the cutting and punching mechanism 5. The cleaning and drying machine is provided to remove dirt on the surface of the foil strip group 20, thereby facilitating reliable welding of the foil strip group 20 at a predetermined position, which is beneficial to improving the quality and precision of the foil strip group 20.

[0071] See also Figure 1-8 The present invention provides a flexible connection production process, comprising the following steps:

[0072] S1: According to the preset increment of the length of each foil strip 10, a plurality of unwinding wheels 11 rotating at different speeds respectively unwind a plurality of foil strips 10 along the conveying direction at a preset speed;

[0073] S2: The laminating mechanism 2 receives and collects a plurality of the foil strips 10 for lamination to form a foil strip group 20;

[0074] S3: The welding machine 3 performs welding connection on the delivered foil strip group 20 at a preset position;

[0075] S4: the bending machine 4 bends the foil strip group 20 according to the preset increment of the length of each foil strip 10 in the foil strip group 20;

[0076] S5: The cutting and punching mechanism 5 cuts the bent and welded portion of the foil strip group 20 into required lengths.

[0077] It should be noted that the preset increment of the length of each foil strip 10 may be greater than zero or may be equal to zero, but the main production process is the above process. Each unwinding wheel 11 unwinds at different or the same rate according to the actual increment of each corresponding foil strip 10. Because the increment of each foil strip 10 is calculated in advance, the increment of each foil strip 10 is also preset in advance, so that the unwinding speed of the unwinding wheel 11 can be preset in advance. There are at least two foil strips 10, for example, two, three, five, eight or nine. The pressing mechanism 2 collects and overlaps multiple foil strip groups 20 through at least one set of pressing wheels 21 to form a foil strip group 20; then the welding machine 3, the bending machine 4 and the cutting and punching mechanism 5 process and shape the foil strip group 20 in turn.

[0078] See also Figure 6-8 As an optional embodiment of the present invention, the soft connection production process comprises the following steps:

[0079] S21: when the preset increment is greater than zero, the pressing mechanism 2 receives and collects the plurality of foil strips 10 and overlaps them to form a foil strip group 20;

[0080] S31: The welding machine 3 first welds a welding area 31 at a predetermined position of the delivered foil strip group 20;

[0081] S4: the bending machine 4 bends the foil strip group 20 according to the preset increment of the length of each foil strip 10 in the foil strip group 20, and forms at least one bending point;

[0082] S32: the welding machine 3 welds another welding area 31 on the side of the foil strip group 20 conveyed by the welding machine 3, where the bending point is away from the welding area 31, so that a foil strip unit 30 having at least two welding areas 31 is formed in the foil strip group 20;

[0083] S5: The punching mechanism 5 cuts the portion of the foil tape group 20 having the foil tape unit 30 into a desired length.

[0084] It should be noted that when the preset increment is greater than zero, that is, the lengths of the multiple foil strips 10 in the foil strip group 20 are different, in the soft connection production process at this time, the pressing mechanism 2 receives the multiple foil strips 10 unwound by the unwinding mechanism 1, and makes the multiple foil strips 10 enter the gap between a group of pressing wheels 21 arranged up and down together. Since the size of the gap is adjustable, the size of the foil strip group 20 in the thickness direction can be controlled to be gathered and stacked into the foil strip group 20; when the welding machine 3 welds the foil strip group 20, generally a welding area 31 is first welded at a predetermined position of the foil strip group 20, and the welding area 31 generally serves as the foil strip unit 3. 0, after all the foil strips 10 at one end of the foil strip unit 30 are welded and fixed, the bending machine 4 bends the foil strip group 20 according to the preset increment of the length of each foil strip 10 in the foil strip group 20, and forms at least one bending point, or multiple bending points. The one or more bending points can fully utilize the increment of each foil strip 10 in the foil strip group 20. After the increment of the predetermined foil strip unit 30 of the foil strip group 20 is fully bent and fully utilized, the other end of the foil strip unit 30 is welded by the welding machine 3, so that multiple foil strips 10 at the other end of the foil strip unit 30 are welded and fixed. The unfolded view of the foil strip unit 30 with increment is not straight. Finally, the cutting and punching mechanism 5 cuts off the part of the foil strip group 20 with the foil strip unit 30 according to the required length. It should be understood that the cut foil strip unit 30 is a foil strip unit 30 that has been bent and welded at both ends.

[0085] See also Figure 2-5 As an optional embodiment of this case, the soft connection production process includes the following steps:

[0086] S22: when the preset increment is zero, the pressing mechanism 2 receives and collects a plurality of the foil strips 10, overlaps them to form a foil strip group 20, and / or presses the foil strips 10 at a preset length position;

[0087] S33: the welding machine 3 performs welding connection on the delivered foil tape set 20 at the compressed position, so that a foil tape unit 30 having at least two welding areas 31 is formed in the foil tape set 20;

[0088] S4: the bending machine 4 bends each of the foil tape units 30, wherein, among the total number of bendings, the bending direction of a part of the bending times is opposite to the bending direction of the remaining bending times, and the bending increment of the part of the bending times is offset by the bending increment of the remaining bending times. Generally, the bending machine 4 bends each of the foil tape units 30 an even number of times, and the bending direction of half of the times is opposite to the bending direction of the other half of the times;

[0089] S52: The cutting mechanism 5 cuts the portion of the foil tape group 20 having the foil tape unit 30 into a desired length.

[0090] It should be noted that when the preset increment is zero, that is, the length of each foil strip 10 in the foil strip group 20 is equal, in the soft connection production process at this time, the pressing mechanism 2 receives the multiple foil strips 10 unwound by the unwinding mechanism 1, and makes the multiple foil strips 10 enter the gap between a group of pressing wheels 21 arranged up and down together. Since the size of the gap is adjustable, the size of the foil strip group 20 in the thickness direction can be controlled to be gathered and overlapped into a foil strip group 20, and the preset length position in the length direction of the foil strip group 20 is pressed tightly. The pressing position is generally the position where the welder 3 welds the foil strip group 20, so as to improve the welding quality. When the welder 3 welds the foil strip group 20, it can first weld out a foil strip unit 30 with at least two welding areas 31. Generally, because the preset increment of the foil strip 10 is zero, the two welding areas 31 are located at At both ends of the foil unit 30 in the length direction, after the two ends of the foil unit 30 are welded and fixed, the position between the two welding areas 31 of the foil unit 30 is welded an even number of times by the bending machine 4, and the bending direction of half of the times is opposite to the bending direction of the other half of the times, so that the increments generated by the bending cancel each other out in the positive and negative directions, so that the increment of the foil 10 of the foil unit 30 is close to zero or equal to zero, and the increment can be ignored, so that the foil unit 30 has no increment. No matter how complex the bending structure of the flexible connection 40 without increment is, its unfolded diagram is flat because the increment is offset. Finally, the cutting mechanism 5 cuts off the part of the foil group 20 having the foil unit 30 according to the required length. It should be understood that the cut foil unit 30 is a foil unit 30 that has been bent and welded at both ends.

[0091] As an optional embodiment of the present case, the soft connection production process includes the following steps:

[0092] After the foil tape group 20 is welded by the welding machine 3, the oxidation grinder 6 grinds the welded areas of the foil tape group 20 in sequence;

[0093] After the foil tape set 20 is polished by the and / or oxidation polishing machine 6, the foil tape set 20 is cleaned and dried by the cleaning and drying machine;

[0094] And / or before the welding machine 3 welds the foil strip group 20, the cleaning and drying machine cleans and dries the foil strip 10.

[0095] It should be noted that after the preset position of the foil strip group 20 is welded and formed by the welding machine 3, the oxidation grinder 6 can at least grind the welded area 31 of the preset position of the foil strip group 20 in sequence. On the one hand, it can remove the welding points, welding blocks and burrs, making the connection smoother and improving the appearance quality. On the other hand, the smoother surface of the soft connection 40 can reduce resistance, improve the current conduction efficiency, and reduce energy consumption and heat generation.

[0096] In this case, after the foil strip group 20 is polished by the oxidation polisher 6, the cleaning and drying machine cleans and dries the foil strip group 20, which can remove impurities and pollutants, improve surface quality, and prevent oxidation and corrosion; before the foil strip group 20 is welded by the welding machine 3, the cleaning and drying machine cleans and dries the foil strip 10, which can ensure welding quality, such as removing the surface oxide layer, reducing welding defects, and improving the welding environment.

[0097] As an optional embodiment of the present case, the plurality of foil strips 10 include nickel strips and / or copper strips and / or aluminum strips and / or steel strips, and the foil strips 10 are generally foil strips 10 made of metal materials. However, it should be understood that when the flexible connection 40 includes multiple layers of foil strips 10, in addition to the outer layer, the inner layer may have a foil strip 10 made of a non-metallic material.

[0098] The present invention replaces the cumbersome process of separate lamination, separate welding, separate grinding and separate punching equipment before the improvement through a complete process flow, designs a flexible connection production process, concentrates lamination, welding, bending and punching on one production line, reduces the turnover of multiple processes, reduces labor costs, and is suitable for flexible connection 40 structures with complex structures and long unfolded lengths.

[0099] The present invention controls the nine copper foil strips 10 unwinding wheels 11 to rotate at different rates through nine motors respectively. The rotation speed can be adjusted according to the required increment of the soft connection 40, thereby controlling the required increment of the soft connection 40. The front and rear ends or one end of the soft connection 40 are welded in advance by a welding device, and then moved to a bending machine 4 for bending. The bending fixture 41 is used to rotate the required angle, and finally punching is performed, thereby improving the production rate and avoiding the problem of low incremental accuracy of traditional manual control.

[0100] In summary, the present invention effectively overcomes some practical problems in the prior art and thus has high utilization value and use significance.

[0101] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
