Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a cutting device. Additionally, this utility model also relates to a production line. Background Technology

[0002] Copper busbars are commonly used electrical connectors, comprising a flexible busbar in the middle, and flexible and rigid connections welded to both ends of the flexible busbar. Copper busbars are widely used in the new energy field as conductive connectors for automotive battery packs. Before being cut to the required length, the flexible busbar is a continuous, uninterrupted busbar wire. It needs to be cut to the required length at the unwinding point, dividing it into short segments of a defined length, which are then used as raw materials for the next processing step.

[0003] The existing process for cutting busbars typically involves feeding pre-extruded busbars into a cutting machine, followed by manual punching and placement, repeating this process continuously. Furthermore, the feeding of the busbars must be stopped during punching, causing production slowdowns and significantly impacting efficiency. The punched soft busbars often exhibit large length errors, failing to meet usage requirements. Due to the characteristics of the punching machine, the ends of the soft busbars may suffer from dented or beveled edges, requiring further welding and milling. Clearly, the existing cutting process is cumbersome, resulting in high labor costs, significant equipment investment, material waste, and low production efficiency. Utility Model Content

[0004] In view of this, the present invention aims to provide a cutting device to improve the processing efficiency of flexible busbars for copper busbars.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A cutting device for cutting long strips of material into small segments, the cutting device including a base, and a cutting mechanism and a length-fixing mechanism that can be synchronously reciprocated on the base; the cutting mechanism is provided with a clamping unit that can be controlled to clamp the material, and a cutting tool for cutting the material; the length-fixing mechanism has a front feeding assembly, a blocking assembly and a rear feeding assembly arranged sequentially along the feeding direction of the material;

[0007] The front feeding assembly can drive the cut segment to the rear feeding assembly; when the end of the material reaches the blocking assembly, the blocking assembly can be triggered to send a control signal; the rear feeding assembly is used to drive the segment out.

[0008] Furthermore, the cutting tool is a saw blade or a milling cutter; the cutting mechanism is equipped with a drive cylinder for driving the cutting tool to move to perform the cutting action.

[0009] Furthermore, the clamping unit uses a cylinder-driven clamping block to clamp the material.

[0010] Furthermore, the cutting mechanism is equipped with a pressure roller, which abuts against the material to confine the material to a set travel path.

[0011] Furthermore, both the rear feeding assembly and the front feeding assembly are equipped with rubber-coated wheels that rotate under the drive of a motor. The rubber-coated wheels abut against the small segment to drive the small segment to move.

[0012] Furthermore, the rear feeding assembly includes a swingable connecting plate and a tension spring acting on the connecting plate; the rubber-coated wheel is located at the swing end of the connecting plate, and under the traction of the tension spring, the connecting plate swings toward the small segment so that the rubber-coated wheel abuts against the small segment.

[0013] Furthermore, the blocking assembly includes a vertically movable lifting slider, a displacement sensor disposed on the lifting slider, and a stop block disposed on the displacement sensor; driven by the lifting slider, the stop block moves between a first position that can block the material and a second position that allows the small segment to pass; the end of the material abuts against the stop block located at the first position, thereby triggering the displacement sensor to send a control signal.

[0014] Furthermore, the blocking component also includes a first photoelectric switch, which is used to detect whether the small segment or the material exists at the first position.

[0015] Furthermore, the position of the blocking component on the fixed-length mechanism is adjustable.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This utility model discloses a cutting device in which the cutting mechanism and the length-fixing mechanism are reciprocating. These two mechanisms can be controlled to move between a receiving position near the feeding unit and a discharge position near the unloading conveying unit. When in the receiving position, the end of the input material reaches the blocking component, triggering the blocking component to send a control signal, causing the cutting mechanism and the length-fixing mechanism to move towards the discharge position. During this movement, the cutting mechanism clamps the material and continuously feeds it, simultaneously completing the cutting operation. The cut segments can quickly travel to the rear feeding component under the drive of the front feeding component, and when the cutting mechanism and the length-fixing mechanism reach the discharge position, the rear feeding component drives the segments out of the cutting device. Afterwards, the cutting mechanism and the length-fixing mechanism can be controlled to quickly return to the receiving position before the subsequent input material reaches the set cutting length, for the next cycle of operation. The entire cutting operation maintains continuous material feeding, significantly improving the production efficiency of cutting long strip wire materials such as copper busbars.

[0018] Furthermore, using a rotating saw blade or milling cutter for cutting can prevent issues such as collapsed or beveled edges at the ends of small segments caused by traditional punching methods, thus improving the flatness of the cut end faces of small copper busbar segments. The clamping method, employing a cylinder-driven clamping block, along with a base plate on the cutting mechanism and side plates for limiting the material's path, utilizes upper and side clamping units to clamp the material in both vertical and horizontal directions. The control and driving method is simple and effective, facilitating technical implementation.

[0019] Another objective of this invention is to provide a production line comprising a feeding unit arranged sequentially, the cutting equipment described in this invention, and a discharge conveying unit; the feeding unit is used to input the material into the cutting equipment, the discharge conveying unit is used to receive the small segments discharged by the cutting equipment, and the cutting mechanism and the length-fixing mechanism reciprocate between a receiving position near the feeding unit and a discharge position near the discharge conveying unit.

[0020] Furthermore, it also includes a feeding device and a feeding cart located downstream of the feeding conveying unit. The feeding device is capable of grabbing the small segment on the feeding conveying unit and placing the small segment onto the feeding cart.

[0021] This utility model's production line, by configuring a feeding unit, cutting equipment, and unloading conveying unit, can accept material input and produce small segments of a set length. Since the cutting mechanism and the length-fixing mechanism can reciprocate between the receiving position and the discharge position, by configuring an electrical control cabinet for the entire cutting equipment, and configuring control units such as PLCs in the electrical control cabinet, the movement of the cutting mechanism and the length-fixing mechanism, as well as the clamping and cutting actions of the cutting mechanism, can be flexibly controlled using signals sent by the blocking components. This effectively achieves uninterrupted material input and small segment cutting processing, which can greatly improve processing and production efficiency. Attached Figure Description

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0045] In the description of this utility model, it should be stated that if terms indicating orientation or positional relationship, such as "up," "down," "left," "right," "front," "back," "inner," and "outer," appear, they are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Taking the production line described in this utility model as an example, the directional terms such as "up," "down," "left," "right," "front," and "back" used in the embodiments are based on the material feeding direction. X in the figure shows the feeding direction, with the side pointed to by the arrow being "front," and the opposite being "back." Above the site where the equipment is located is "up," and below is "down." The width direction of the production line, i.e., the left-right direction, is located in the direction perpendicular to the feeding direction within the water surface.

[0046] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances. The limiting terms such as "first," "second," "A," "B," "C," and "D" appearing in the description of this utility model are merely for distinguishing similar features in different locations, attributions, or uses, in order to avoid ambiguity and confusion, and should not be construed as indicating or implying relative importance.

[0047] In addition, the busbar wire mentioned in the embodiments of this utility model refers to the raw material of the flexible busbar before cutting. It consists of multiple rolls of copper strip unwound together, with the ends stacked on top of each other. Then, it is fed into an extrusion line, where mica tape is wound around it, and an insulation layer is extruded and coated. Since it is a long, coiled strip, it needs to be cut to a set length to form the flexible busbar for processing copper busbars. The flexible busbar is the main body of the copper busbar. Its two ends are welded with a flexible connection (flexible busbar, using multi-layer copper sheets, welded by a servo-cylinder copper polymer diffusion welding machine, and then punched out) and a rigid connection (rigid busbar, using a single layer of copper plate of a certain thickness, punched out) to form a complete copper busbar. At the welding joint, half the thickness can be milled on each side to form a step of a certain length, which is then spliced ​​and welded with a copper polymer diffusion welding machine. For the parts other than the flexible busbar, including the welding parts, subsequent processes require wrapping with mica and using heat shrink tubing for insulation treatment, finally forming the finished product.

[0048] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] Example 1

[0050] This embodiment relates to a cutting device for receiving busbar wire 900 as input and cutting the busbar wire 900 into flexible busbars 90 for processing copper busbars 9, which can improve the processing efficiency of the flexible busbars 90 of copper busbars 9; an exemplary structure is as follows: Figure 1 , Figure 2 and Figure 3 As shown.

[0051] Overall, the cutting device includes a base 60, and a cutting mechanism 6 and a length-fixing mechanism 7 that can reciprocate synchronously on the base 60. The cutting mechanism 6 is equipped with a clamping unit that can be controlled to clamp the busbar wire 900, and a cutter for cutting the busbar wire 900. The length-fixing mechanism 7 has a front feeding assembly 73, a blocking assembly 74, and a rear feeding assembly 72 arranged sequentially along the feeding direction of the busbar wire 900. The front feeding assembly 73 drives the cut soft busbar 90 to the rear feeding assembly 72; when the end of the busbar wire 900 reaches the blocking assembly 74, the blocking assembly 74 can be triggered to send signals to control the movement of the cutting mechanism 6 and the length-fixing mechanism 7, and to control the cutting mechanism 6 to clamp and cut the busbar wire 900; the rear feeding assembly 72 drives the soft busbar 90 out.

[0052] It should be noted that the cutting equipment of this utility model is suitable for cutting various long strip-shaped wire materials into small segments of a set length; it is particularly suitable for the copper busbar production field, used to receive the input of busbar wire 900 and cut the busbar wire 900 into flexible busbars 90 for processing copper busbars 9. This embodiment uses the processing of busbar wire 900 as an example for explanation; the busbar wire 900 mentioned in the embodiment corresponds to the material described above, and the flexible busbar 90 mentioned in the embodiment corresponds to the small segment mentioned above.

[0053] For the cutting tool on the cutting mechanism 6, common punching tools can certainly be used; however, preferably, a saw blade 660 or a milling cutter is used. In this embodiment, the tool is a saw blade 660, which is disc-shaped and mounted on a table saw 66. It rotates under the drive of a motor to perform sawing and cutting operations. At the same time, the cutting mechanism 6 in this embodiment is provided with a drive cylinder 65 for driving the tool to move to perform the cutting action. When cutting is required, the drive saw blade 660 moves down to contact the busbar wire 900, and the busbar wire 900 can be cut. Using a rotating saw blade 660 or a milling cutter for cutting operations can prevent the collapse or bevel of the end of the soft busbar 90 caused by traditional punching methods, which is beneficial to improving the flatness of the cut end face of the soft busbar 90 of the copper busbar 9.

[0054] In addition, such as Figure 2 As shown, the clamping unit in this embodiment uses a cylinder-driven clamping block to clamp the busbar wire 900. This cylinder-driven clamping method, combined with the base plate on the cutting mechanism 6 and the side plate used to limit the travel path of the busbar wire 900, utilizes the upper clamping unit 67 and the side clamping unit 68 to clamp the busbar wire 900 in both vertical and horizontal directions. The control and driving method is simple and effective, facilitating technical implementation. After being clamped by the clamping unit, not only is the position of the busbar wire 900 fixed on the cutting mechanism 6 for cutting operations, but also, during the time period from clamping the busbar wire 900 to cutting it, the cutting mechanism 6 and the length-fixing mechanism 7 can move synchronously in the feeding direction according to the feeding speed of the busbar wire 900, thus providing good driving force for the feeding of the busbar wire 900 and allowing the cutting operation and continuous feeding to be synchronized well.

[0055] Meanwhile, the cutting mechanism 6 in this embodiment is also equipped with a clamping roller, which abuts against the busbar wire 900 to confine the busbar wire 900 to a predetermined travel path. By providing clamping rollers such as the upper clamping roller 63 and the side clamping roller 64 on the cutting mechanism 6, the busbar wire 900 can be effectively confined to the predetermined travel path, ensuring the smooth movement of the busbar wire 900 while reliably regulating its position in the vertical and horizontal directions of the equipment. The horizontal direction referred to here is the same as the horizontal direction mentioned above, referring to the direction perpendicular to the feeding direction in the horizontal plane. To better guide the busbar wire 900 into the cutting mechanism 6, an inlet guide groove 62 is provided on the feeding side of the cutting mechanism 6. The busbar wire 900 enters the cutting mechanism 6 through the inlet guide groove 62 and travels along the "L"-shaped limiting surface formed by the bottom plate and the side plate. The aforementioned upper pressing wheel 63 and side pressing wheel 64 are arranged close to the inlet guide groove 62 and press the busbar wire 900 against the bottom plate and the side plate, so that the busbar wire 900 moves along a fixed path.

[0056] For the setting of the fixed-length mechanism 7, there are of course many different structural schemes to choose from. In this embodiment, such as... Figures 3 to 6 As shown, the blocking assembly 74 includes a vertically movable lifting slider 742, a displacement sensor 744 disposed on the lifting slider 742, and a stop block 747 disposed on the displacement sensor 744. Driven by the lifting slider 742, the stop block 747 moves between a first position that can block the busbar 900 and a second position that allows the flexible busbar 90 to pass through. The end of the busbar 900 abuts against the stop block 747 located in the first position, which can trigger the displacement sensor 744 to send a control signal.

[0057] By setting a lifting slider 742, which is movably and guideably mounted on a lifting bracket 740, the lifting slider 742 can move up and down smoothly under the drive of a lifting drive cylinder 741 or other driving device, so that the stop 747 can switch between a first position and a second position. The stop 747 is mounted on a displacement sensor 744. When the end of the busbar 900 contacts the stop 747, it presses against the stop 747, triggering the displacement sensor 744 to send a signal. Preferably, in this embodiment, the stop 747 is mounted on a guide shaft 745, which is movably and guideably mounted in the displacement sensor 744 along the feeding direction. A compression spring 746 is provided between the guide shaft 745 and the displacement sensor 744. When the stop 747 is pressed by the busbar wire 900, it drives the guide shaft 745 to retract into the displacement sensor 744 and compress the spring 746. When the pressing force reaches the set stable state, the signal detected by the displacement sensor 744 also tends to stabilize, thus confirming that the length of the busbar wire 900 entering the cutting equipment to be cut meets the set cutting length requirement, thereby ensuring the error accuracy of the length of the sawn soft busbar 90. Obviously, the entire process described above should be carried out when the cutting mechanism 6 and the length fixing mechanism 7 are in the receiving position.

[0058] Furthermore, the blocking component 74 in this embodiment also includes a first photoelectric switch 743, which is used to detect whether a flexible busbar 90 or a busbar wire 900 exists at the first position. By setting the first photoelectric switch 743 on the blocking component 74, it is possible to detect in real time whether a flexible busbar 90 passes below the block 747 when it is in the upper position; after the flexible busbar 90 is cut out, the block 747 will rise to the second position in time to allow the flexible busbar 90 to pass through. After the flexible busbar 90 has completely passed through, the first photoelectric switch 743 can detect and confirm that it has completely passed through, thereby triggering the block 747 to return to the first position, thereby detecting the subsequent arrival of the busbar wire 900.

[0059] For the specific configuration of the rear feeding assembly 72 and the front feeding assembly 73, the following scheme is preferred. For example... Figure 7 , Figure 8 As shown, both the rear feeding assembly 72 and the front feeding assembly 73 are equipped with rubber-coated wheels 725 that rotate under the drive of a motor. The rubber-coated wheels 725 abut against the flexible busbar 90 to drive the flexible busbar 90 to move. By using a motor to drive the rubber-coated wheels 725, the rotation speed of the rubber-coated wheels 725 can be well controlled. After the outer surface of the rubber-coated wheels 725 is pressed against the busbar wire 900 (or the cut flexible busbar 90), and the movement direction of the rubber-coated wheels 725 is kept in the same direction as the feeding direction, the friction force exerted by the rubber-coated wheels 725 on the busbar wire 900 (or the flexible busbar 90) drives the busbar wire 900 to move at a set feeding speed, or allows the flexible busbar 90 to move quickly at a required faster speed.

[0060] Specifically, the rear feeding assembly 72 includes a swingable connecting plate 726 and a tension spring 723 acting on the connecting plate 726. A rubber-coated wheel 725 is located at the swinging end of the connecting plate 726. Pulled by the tension spring 723, the connecting plate 726 swings towards the flexible busbar 90, causing the rubber-coated wheel 725 to press against the flexible busbar 90. A first drive motor 721 is fixed to the table 70 via a motor mounting base 722. The first drive motor 721 drives the rubber-coated wheel 725 to rotate via a synchronous belt assembly 724. The tension spring 723 is connected between the middle of the connecting plate 726 and the table 70. By placing the tension spring 723 between the rear feeding assembly 722 and the table 70, and by adjusting the tension spring 723, suitable pressure can be generated between the rubber-coated wheel 725 and the flexible busbar 90, thereby meeting the driving requirements of the flexible busbar 90. Additionally, it should be noted that, as mentioned above, since the required travel speed of the materials (busbar wire 900 and flexible busbar 90) differs at different working stages, the first drive motor 721 is preferably a servo motor. The aforementioned front feeding assembly 73 can be configured in the same way as the aforementioned rear feeding assembly 72.

[0061] Furthermore, similar to the arrangement of the clamping rollers on the cutting mechanism 6, the length-fixing mechanism 7 in this embodiment is equipped with an upper clamping guide roller 75 and a side clamping guide roller 76. These, in conjunction with the limiting baffle on the table 70, ensure that the flexible busbar 90 travels along the set path. Additionally, as... Figure 1 As shown, to achieve the reciprocating movement of the cutting mechanism 6 and the length-fixing mechanism 7 on the base 60, there are various driving methods. In this embodiment, one end of the base 60 is provided with a reciprocating drive mechanism 61. This reciprocating drive mechanism 61 uses a motor to drive a screw, and through screw transmission, guides the frame carrying the cutting mechanism 6 and the length-fixing mechanism 7 to move on the base 60. To adapt the control circuits of the cutting mechanism 6 and the length-fixing mechanism 7 to their reciprocating movement requirements, the circuits can be arranged using a cable harness drag chain 77. The cable harness drag chain 77 can move with the movement of the cutting mechanism 6 and the length-fixing mechanism 7, preventing the circuits from becoming cluttered.

[0062] like Figure 3As shown, the blocking component 74 in this embodiment is preferably configured to be position-adjustable on the length-fixing mechanism 7. The adjustable position of the blocking component 74 on the length-fixing mechanism 7 allows for flexible changes in the length specification of the flexible busbar 90, i.e., changing the set cutting length. In this embodiment, the blocking component 74 is mounted on a guide seat, which is slidably disposed on the table 70 of the length-fixing mechanism 7 along the feeding direction. A position adjustment component 71 is provided at the end of the table 70 away from the cutting mechanism 6. The position adjustment component 71 is equipped with a handwheel and a screw, and the screw is connected to the guide seat in a transmission manner. Rotating the handwheel drives the screw to rotate, which in turn moves the guide seat and the blocking component 74 thereon, achieving precise adjustment of the position of the blocking component 74.

[0063] In summary, in this embodiment, the cutting device employs a reciprocating motion for the cutting mechanism 6 and the length-fixing mechanism 7. These two mechanisms can be controlled to move between a receiving position near the feeding unit 5 and a discharge position near the unloading conveying unit 8. When in the receiving position, the blocking component 74 is triggered when the end of the input busbar 900 reaches it, causing it to issue a control signal that initiates the movement of the cutting mechanism 6 and the length-fixing mechanism 7 towards the discharge position. During this movement, the cutting mechanism 6... The device can clamp the busbar wire 900 and continuously feed it, while simultaneously completing the cutting operation of the busbar wire 900. The cut flexible busbar 90 can quickly move to the rear feeding component 72 under the drive of the front feeding component 73, and when the cutting mechanism 6 and the length-fixing mechanism 7 reach the discharge position, the rear feeding component 72 drives the flexible busbar 90 out of the cutting equipment. Afterwards, the cutting mechanism 6 and the length-fixing mechanism 7 can be controlled to quickly return to the receiving position before the subsequent input busbar wire 900 is fed to the set cutting length, so as to carry out the next cycle of operation. The device can maintain the continuous feeding of the busbar wire 900 throughout the entire cutting operation, which is beneficial to improving the processing efficiency of the flexible busbar 90 of the copper busbar 9.

[0064] Example 2

[0065] This embodiment relates to a production line, including a feeding unit 5 arranged sequentially, the cutting equipment provided in Embodiment 1, and a feeding conveyor unit 8. For example... Figure 9 As shown, the cut flexible busbar 90 is formed by welding flexible connections 91 and rigid connections 92 to its two ends respectively. An exemplary arrangement of the production line in this embodiment is as follows: Figure 10 As shown.

[0066] The feeding unit 5 is used to input the busbar wire 900 into the cutting equipment, the unloading conveying unit 8 is used to receive the soft busbar 90 discharged from the cutting equipment, and the cutting mechanism 6 and the fixed length mechanism 7 reciprocate between the receiving position near the feeding unit 5 and the discharge position near the unloading conveying unit 8.

[0067] By configuring the feeding unit 5, the cutting equipment, and the unloading conveying unit 8, the system can receive the input of busbar wire 900 and produce soft busbars 90 of a set length. Since the cutting mechanism 6 and the length-fixing mechanism 7 can reciprocate between the receiving position and the unloading position, by configuring the entire cutting equipment with an electrical control cabinet 2 and configuring control units such as PLC in the electrical control cabinet 2, the movement of the cutting mechanism 6 and the length-fixing mechanism 7, as well as the clamping and cutting actions of the cutting mechanism 6, can be flexibly controlled using the signals sent by the blocking component 74. This effectively realizes the uninterrupted input of busbar wire 900 and the cutting of soft busbars 90, which can greatly improve the processing and production efficiency.

[0068] Furthermore, the production line in this embodiment also includes a feeding device 4 and a feeding cart 3 located downstream of the feeding conveyor unit 8. The feeding device 4 can grab the flexible busbars 90 on the feeding conveyor unit 8 and place them onto the feeding cart 3. By setting up the feeding device 4 and the feeding cart 3 downstream of the feeding conveyor unit 8, the flexible busbars 90 conveyed by the feeding conveyor unit 8 can be promptly sorted and stacked onto the feeding cart 3, and then pushed to the next processing line, giving the entire production line a better production cycle and more complete production functions. To improve safety, a protective fence 1 can also be added around the entire production line.

[0069] Specifically, such as Figure 11 As shown, the feeding unit 5 includes a frame 50, side guide wheels 52, guide wheel sets 53, and drive wheel sets mounted on the frame 50. The side guide wheels 52 and guide wheel sets 53 constrain the busbar cable 900 on the feeding unit 5 in the vertical and horizontal directions, allowing the busbar cable 900 to move along a predetermined path. The drive wheel set includes a follower wheel 55 and a drive wheel 54 that rotate under the drive of a second drive motor 56. The busbar cable 900 is clamped between the follower wheel 55 and the drive wheel 54, thus obtaining forward propulsion. To effectively protect personnel and equipment, a protective cover 51 is provided on the frame 50, and an observation window 510 is provided on the protective cover 51. A transparent plastic plate or glass can be installed on the observation window 510 for easy observation. The aforementioned drive wheel 54 and follower wheel 55 are preferably rubber-coated wheels, and the second drive motor 56 is preferably a servo motor, so as to effectively protect the surface of the busbar wire 900 from damage and to flexibly adjust the feeding speed of the busbar wire 900. The busbar wire 900 enters through the inlet 511 of the feeding unit 5 and exits through the outlet 512, thereby entering the cutting mechanism 6.

[0070] like Figure 12 , Figure 13As shown, the flexible busbar 90 discharged by the fixed-length mechanism 7 falls onto the belt conveyor 81 of the unloading conveyor unit 8, reaches its end along the belt conveyor 81, and is blocked by the end baffle 84. Then, driven by the pusher plate 83 driven by the pusher cylinder 82, the flexible busbar 90 reaches the position defined by the positioning plate 86. A second photoelectric switch 85 is provided at the positioning plate 86 to detect whether the flexible busbar 90 is at the defined position. When the flexible busbar 90 is detected to be in place, a signal can be sent to control the unloading device 4 to perform a material grabbing action.

[0071] The unloading device 4 in this embodiment includes a mounting base 40 and a robot 41 mounted on the mounting base 40. The robot 41 carries an unloading gripper 42 and moves between the unloading conveyor unit 8 and the unloading cart 3. The unloading gripper 42 can perform the actions of gripping and releasing the soft busbar 90. After the unloading gripper 42 reaches the position above the positioning plate 86, it grips the soft busbar 90. Then, the robot 41 moves, driving the unloading gripper 42 to the unloading tray 30 of the unloading cart 3. The unloading gripper 42 releases the soft busbar 90, causing it to fall into the material distribution grid set on the unloading tray 30. The continuously arriving soft busbars 90 will be stacked on the unloading tray 30. To facilitate the movement of the unloading gripper 42 at the positioning plate 86, a gripper avoidance opening 860 can be opened on the positioning plate 86 to avoid the unloading gripper 42. To facilitate the unloading cart 3 to enter and exit the designated position in the protective fence 1, a unloading cart positioning guide mechanism 31 can be set at the designated position.

[0072] Since each unloading cart 3 will be removed from the protective fence 1 and sent to the next production line after it is full of soft busbars 90, the production line in this embodiment is equipped with two unloading carts 3 for transfer and rotation, so that the unloading equipment 4 can uninterrupt the unloading. After one unloading cart 3 is full of soft busbars 90, the unloading equipment 4 can continue to stack soft busbars 90 on another unloading cart 3, and the entire production process does not need to be stopped.

[0073] Based on the overall setup described above, the general working principle of the production line in this embodiment is as follows:

[0074] After the busbar wire 900 enters the cutting mechanism 6 through the feeding unit 5, it slides forward under the pressure and guidance of the upper clamping roller 63 and the side clamping roller 64. After passing through the cut at the saw blade 660, it continues to slide forward and finally moves to the blocking component 74 of the length-fixing mechanism 7, where it is blocked by the stop block 747. At this time, the cutting mechanism 6 and the length-fixing mechanism 7 as a whole move forward at the same speed as the busbar wire 900 under the drive of the reciprocating drive mechanism 61. Then, the upper clamping unit 67 and the side clamping unit 68 on the cutting mechanism 6 press and fix the busbar wire 900 on the cutting mechanism 6. The table saw 66 moves downward under the drive of the drive cylinder 65, and the saw blade 660 cuts the busbar wire 900. Throughout the entire working process, the feeding speed of the busbar wire 900 is uniform, and it continuously feeds and produces soft busbars 90 until this batch of busbar wire 900 is used up. To prevent material from accumulating and sagging on the front of the busbar 900 during the cutting process, the table saw 66 needs to perform a flying cut during the sawing process.

[0075] After the table saw 66 cuts the busbar wire 900, the drive cylinder 65 drives the table saw 66 to lift, so that subsequent busbar wires 900 can continue to be fed through; at the same time, the upper clamping unit 67 and the side clamping unit 68 retract, releasing the cut soft busbar 90. At this time, the front feeding component 73 on the fixed length mechanism 7 has received the soft busbar 90, and the front feeding component 73 starts to perform friction conveying of the soft busbar 90, and the speed is greater than the feeding guide conveying speed of the previous busbar wire 900, so as to achieve the purpose of quickly sending the soft busbar 90 away.

[0076] After the table saw 66 cuts the busbar wire 900 to produce a flexible busbar 90, the cut flexible busbar 90 is quickly moved to the end of the fixed-length mechanism 7 under the drive of the rear feeding assembly 72. At this time, the cutting mechanism 6 and the fixed-length mechanism 7 also reach the discharge position, and the fixed-length mechanism 7 will convey the flexible busbar 90 to the unloading conveyor unit 8. Afterwards...

[0077] Under the reverse driving action of the reciprocating drive mechanism 61, the cutting mechanism 6 and the fixed length mechanism 7 quickly return to the receiving position, wait for the next piece of material to arrive, and continue the next sawing operation.

[0078] Overall, the cutting equipment and production line of this utility model can achieve fully automatic cutting and blanking of busbar wire 900, enabling continuous automated production, reducing manual input, and achieving high production efficiency. Furthermore, the cut flexible busbar 90 has no collapsed or beveled edges at either end, and the surface roughness can reach Ra3.2 level, allowing it to be directly used for welding with flexible connectors 91 and rigid connectors 92, avoiding the need for a separate milling process on the end face of the flexible busbar 90.

[0079] Meanwhile, the length of the cut soft busbar 90 is precisely controlled, with a length error of less than 0.5mm. There is no excess length in the cut, reducing material waste. The equipment has high cutting precision and is not affected by the soft material that is extruded for insulation on the outside of the busbar wire 900 product.

[0080] The above description is merely a preferred embodiment of this utility model. Detailed explanations of configurations, examples of specific structural arrangements, and descriptions of assembly and connection methods are provided to ensure sufficient disclosure so that those skilled in the art can better implement this utility model, and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
