Description

Technical Field

[0001] The present invention relates to the technical field of busbar processing, and particularly to a composite busbar production line and process for new energy vehicles. Background Art

[0002] In the electrical system of new energy vehicles, the composite busbar is a core component. As a multi-layer composite structure connecting row, it is like a power distribution "high-speed channel", connecting battery terminals through welding or bolt connection, etc., to ensure stable current transmission. Its conductors are commonly made of copper, aluminum or copper-aluminum composite strips. Copper has excellent electrical conductivity, and aluminum is beneficial for weight reduction; the composite busbar is widely used in the connection of battery modules, motor controllers, etc. With properties such as low resistance, high voltage and large current resistance, and good insulation, it reduces energy loss, improves endurance, and ensures electrical safety.

[0003] Chinese Patent CN109909370A discloses a busbar production line, including a first conveyor line, a punching and shearing machine, a deburring machine, a second conveyor line, a filleting device, a clamping and conveying mechanism, a pushing mechanism, a flipping and conveying mechanism and a bending machine; the first conveyor line is connected to the punching and shearing machine; the punching and shearing machine receives the busbar and processes it; the deburring machine is arranged on the punching and shearing machine; the filleting device straddles the second conveyor line; the clamping and conveying mechanism is arranged between the second conveyor line and the first conveyor line; the pushing mechanism is arranged on one side of the second conveyor line to push the busbar to the flipping and conveying mechanism; the flipping and conveying mechanism is located on the other side of the second conveyor line and includes a vertical conveying groove and an inclined guide plate. The inclined guide plate is connected to the input port of the vertical conveying groove, and the busbar slides into the vertical conveying groove through the inclined guide plate and is conveyed to the bending machine; the bending machine is connected to the vertical conveying groove for bending the busbar. The present invention improves the processing efficiency of the busbar, reduces costs, and ensures the processing quality of the busbar.

[0004] However, in the actual use process, it is found that in the prior art, when bending the copper bar, only one side of the copper bar is bent each time. For some busbars with symmetrical structures, the bending efficiency is relatively low. Secondly, when bending the end of the copper bar, the length of the already bent copper bar is relatively long and lacks support, and it is easy to bend due to gravity. Finally, when the copper bar extends a certain distance for bending each time, with each extension, the area of the copper bar clamped and fixed becomes smaller, the clamping stability decreases, and the distance extended each time is difficult to accurately control, especially when producing copper bars with a short end after bending, the clamped part is relatively short.

In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0024] Embodiment 1 As Figure 1 and Figures 8 to 12 shown, this embodiment provides a composite busbar production line for new energy vehicles, including a two-way bending mechanism 3, and the two-way bending mechanism 3 includes: A translation assembly 31 arranged on a conveyor belt 200, a clamping assembly 32 arranged on the translation assembly 31 for clamping a copper busbar 100, a fixing assembly 33 arranged below the clamping assembly 32 for fixing the bending position of the copper busbar 100, and a bending component 34 that can adjust the bending position; When bending the two ends of copper busbars of different lengths, the clamping assembly 32 clamps the copper busbar 100 from the previous station, and the translation assembly 31 drives the copper busbar 100 to move to a suitable position. The fixing assembly 33 fixes the copper busbar 100 at the position where it needs to be bent, and the bending component 34 moves to the bending position following the fixing assembly 33, and the bending component 34 bends the copper busbar 100 to the required angle.

[0025] In this embodiment, through the mutual cooperation of the translation component 31, the clamping component 32, the fixing component 33, and the bending component 34 in the two-way bending mechanism 3, the function of simultaneously bending both ends of copper bars 100 with different lengths is realized. Furthermore, the bending efficiency is improved, the stability of the copper bars 100 during the bending process is ensured, and the bending position is accurately controlled. The translation component 31 drives the copper bars 100 to move, transfers the copper bars 100 from the pressing and cutting mechanism 2 to the bending position, and then transfers them to the conveyor belt 200 after the bending is completed. The clamping component 32 firmly clamps the copper bars 100 to prevent the copper bars 100 from shifting during movement and bending. The fixing component 33 accurately positions the bending position of the copper bars 100 to ensure that each bending can meet the expected position requirements. The bending component 34 performs a bending operation on the copper bars 100 according to the position determined by the fixing component 33 to realize the bending and forming of the copper bars 100.

[0026] Furthermore, as Figures 8 to 9 shown, the translation component 31 includes: A support frame 311, and the support frame 311 is arranged on the conveyor belt 200; A second sliding rod 312, and the second sliding rod 312 is arranged on the support frame 311; A second lead screw 313, and the second lead screw 313 is arranged on the support frame 311; A moving seat 314, and the moving seat 314 is sleeved on the second sliding rod 312 and the second lead screw 313; A second motor 315, and the second motor 315 is in transmission connection with the second lead screw 313; A third sliding rod 316, and the third sliding rod 316 is arranged on the moving seat 314; A sliding mounting seat 317, and the sliding mounting seat 317 is sleeved on the third sliding rod 316; A first electric push rod 318, and the ejector rod of the first electric push rod 318 is connected to the sliding mounting seat 317 and is used to change the position of the sliding mounting seat 317.

[0027] In this embodiment, by setting the translation component 31, copper bars 100 with different sizes cut by the pressing and cutting mechanism 2 can be transferred to the bending position, and after the bending is completed, they are transferred to the conveyor belt 200 for collection.

[0028] Specifically, the second motor 315 drives the second lead screw 313 to rotate, and the moving seat 314 moves along the direction of the second slide bar 312. The second slide bar 312 plays a guiding role to ensure the stable movement of the moving seat 314. The moving seat 314 can accurately drive the upper components to move to the required positions, facilitating subsequent operations such as bending the copper bar 100. When the first electric push rod 318 works, its ejector rod expands and contracts, pushing or pulling the sliding mounting seat 317. The third slide bar 316 provides support and guidance for the movement of the sliding mounting seat 317. In this way, according to the actual situation of the copper bar 100, the position of the clamping assembly 32 can be flexibly adjusted to prevent the movement track from being blocked, ensuring that the clamping assembly 32 can accurately clamp the copper bar 100 and improving the accuracy and stability of production.

[0029] Further, as Figures 8 to 9 shown, the clamping assembly 32 includes: A fixed clamping plate 321, which is arranged on the sliding mounting seat 317; A second electric push rod 322, which is installed on the sliding mounting seat 317; A pressing plate 323, which is connected to the ejector rod of the second electric push rod 322 and is used to clamp the copper bar 100 together with the fixed clamping plate 321.

[0030] In this embodiment, by setting the clamping assembly 32, the clamping function of the copper bar 100 is realized, and further, the effect of keeping the copper bar 100 stable during movement and bending and avoiding displacement is achieved.

[0031] Specifically, when it is necessary to clamp the copper bar 100, the second electric push rod 322 is started, and its ejector rod extends. The ejector rod pushes the pressing plate 323 connected to it, and the pressing plate 323 moves towards the fixed clamping plate 321. The fixed clamping plate 321 is fixed on the sliding mounting seat 317 and remains stationary. The pressing plate 323 gradually approaches the fixed clamping plate 321 until the copper bar 100 is tightly clamped between the two and is ensured to be in the middle of the copper bar 100. The advantage of this design is that the second electric push rod 322 can provide stable and adjustable thrust, ensuring that the pressing plate 323 can flexibly adjust the clamping force according to the thickness of the copper bar 100 and other conditions. The fixed clamping plate 321 provides a stable support surface for the copper bar 100. Acting together with the pressing plate 323, it can firmly clamp the copper bar 100, so that the copper bar 100 will not shake or shift due to external forces during subsequent translation, bending and other operations, ensuring the accuracy of processing.

[0032] Further, as Figures 10 to 12 shown, the fixing assembly 33 includes: An installation bottom plate 331; The fourth slide bar 332 is disposed on the mounting base plate 331; The first bidirectional lead screw 333 is disposed on the mounting base plate 331; The third motor 334, the output shaft of the third motor 334 is in transmission connection with the first bidirectional lead screw 333; The sliding frame 335 is sleeved on the fourth slide bar 332 and the first bidirectional lead screw 333, and is symmetrically arranged; The fifth slide bar 336 is disposed inside the sliding frame 335; The second bidirectional lead screw 337; The fourth motor 338, the output shaft of the fourth motor 338 is in transmission connection with the second bidirectional lead screw 337; The fixed pressing plate 339 is sleeved on the fifth slide bar 336 and the second bidirectional lead screw 337, and is symmetrically arranged.

[0033] In this embodiment, by setting the fixing component 33, the precise fixing function of the bending position of the copper bar 100 is realized, so as to ensure that the bending component 34 can perform the two-way bending operation on the copper bar 100 at the accurate position, and improve the accuracy and stability of the bending.

[0034] Specifically, when it is necessary to fix the bending position of the copper bar 100, the third motor 334 is started to drive the first bidirectional lead screw 333 to rotate, and the two sliding frames 335 will move relatively or away from each other along the direction of the fourth slide bar 332, so that the distance between the two sliding frames 335 can be adjusted according to the length of the copper bar 100 to meet the fixing requirements of copper bars 100 of different sizes. The fourth slide bar 332 plays a guiding role to ensure the stable movement of the sliding frame 335; Then, the fourth motor 338 is started to drive the second bidirectional lead screw 337 to rotate, and the two fixed pressing plates 339 will move relatively along the direction of the fifth slide bar 336 to tightly fix the copper bar 100 between the two fixed pressing plates 339 and fix the bending position of the copper bar 100. The fifth slide bar 336 also plays a guiding role to ensure that the fixed pressing plate 339 stably fixes the copper bar 100. This design can precisely adjust the fixing position, and no matter how the length of the copper bar 100 changes, stable and accurate fixing can be achieved, providing a reliable guarantee for the subsequent bending process.

[0035] Further, as Figures 10 to 12 shown, the bending component 34 includes: The telescopic rod 341 is disposed on the mounting base plate 331; A slide rail 342 is provided on the top rod of the telescopic rod 341; A hydraulic rod 343 is provided on the mounting base plate 331, and the top rod is connected to the slide rail 342; A sliding seat 344 is slidably provided on the slide rail 342; A support plate 345 is provided on the sliding seat 344; A bending plate 346 is provided on the support plate 345; A connecting plate 347 is provided on the support plate 345; A fixing plate 348 is provided on the sliding frame 335; A sliding rod 349 is provided on the fixing plate 348 and is also inserted into the connecting plate 347 to drive the bending plate 346 to move.

[0036] In this embodiment, by providing the bending assembly 34, the bending assembly 34 will move together with the fixing assembly 33, and can perform precise bending operations on the copper bar 100 after the fixing assembly 33 fixes the copper bar 100, realizing the efficient processing of the copper bar 100 and improving the production efficiency and product quality.

[0037] Specifically, when the fixing assembly 33 stably fixes the copper bar 100 at the predetermined bending position, the bending assembly 34 starts to work, and the hydraulic rod 343 is responsible for driving the vertical movement of the slide rail 342. In the vertical direction, by controlling the telescopic amount of the top rod of the hydraulic rod 343, the sliding seat 344 can be moved along the slide rail 342 to the upper part of the bending area of the copper bar 100. When bending operations are required, the top rod of the hydraulic rod 343 contracts, driving the slide rail 342 to descend, and then the bending plate 346 installed on the support plate 345 gradually approaches and contacts the copper bar 100. As the hydraulic rod 343 continues to apply pressure, the bending plate 346 bends the copper bar 100 to the set angle. During the whole process, the sliding rod 349 and the connecting plate 347 cooperate closely. Since the fixing plate 348 is fixed on the sliding frame 335, when the position of the sliding frame 335 is finely adjusted, the sliding rod 349 moves accordingly, and it slides inside the connecting plate 347, ensuring that the bending plate 346 can always accurately correspond to the bending point of the copper bar 100, ensuring the accuracy of the bending position. For multiple bends or bends at different angles of the copper bar 100, by readjusting the actions of the hydraulic rod 343 and the position of the sliding frame 335, flexible and variable two-way bending operations can be realized.

[0038] Further, as Figures 1 to 2 shown, it further includes: A copper bar conveying mechanism 1, and the copper bar conveying mechanism 1 includes: Copper bar conveyor 101, the copper bar conveyor 101 is used to release copper bars 100; Base 102; Conveyor rollers 103, multiple groups of the conveyor rollers 103 are rotatably arranged on the base 102, and a rubber sleeve for pressing the copper bar 100 is sleeved on the conveyor roller 103; Pulley 104, the pulley 104 is in transmission connection with the conveyor roller 103; Drive belt 105, the drive belt 105 is used to connect multiple pulleys 104; Conveyor motor 106, the output shaft of the conveyor motor 106 is in transmission connection with the conveyor roller 103.

[0039] In this embodiment, the copper bar conveying mechanism 1 plays a role of accurately, stably and quantitatively conveying the copper bar 100 to the subsequent processes of the production line. Cooperating with the pressing and cutting mechanism 2, the pressing and cutting holes operation is carried out at a suitable position, and the copper bar 100 is pressed and cut into copper bars 100 of different sizes.

[0040] Specifically, when the composite busbar production line is started, the copper bar conveyor 101 starts to work, gradually releasing the coiled or bundled copper bars 100. At this time, the conveyor motor 106 is powered on and runs, and its output shaft drives the connected conveyor roller 103 to rotate. Since multiple conveyor rollers 103 are connected to each other through pulleys 104 and drive belts 105, all conveyor rollers 103 will rotate synchronously under the drive of the conveyor motor 106. The rubber sleeve sleeved on the conveyor roller 103 plays a crucial role. It not only increases the friction with the copper bar 100 to ensure that the copper bar 100 does not slip during the conveying process, but also avoids the direct hard contact between the conveyor roller 103 and the copper bar 100, which may cause scratches on the surface of the copper bar, ensuring the accurate control of the output quantity of the copper bar 100.

[0041] With the continuous rotation of the conveyor roller 103, the copper bar 100 is stably and quantitatively conveyed forward under the action of friction. By controlling the rotation speed of the conveyor motor 106, the conveying speed of the copper bar 100 can be accurately adjusted to match the working rhythm of the pressing and cutting mechanism 2 and the double - way bending mechanism 3. When the pressing and cutting mechanism 2 performs the hole pressing or cutting operation, the conveyor motor 106 stops rotating to ensure the stability of the copper bar 100 during the pressing and cutting process.

[0042] Further, as Figures 3 to 7 shown, it further includes a pressing and cutting mechanism 2, and the pressing and cutting mechanism 2 includes: Lower pressing assembly 21, the lower pressing assembly 21 is used to press holes in the copper bar 100 and cut it into the required length; Switching component 22, which is arranged on the downward pressing component 21 and is used to switch between the operations of punching holes or cutting the copper bar 100.

[0043] In this embodiment, through the coordinated work of the downward pressing component 21 and the switching component 22, the function of diversifying the processing of the copper bar 100 is realized, and then the effects of meeting different production requirements and improving production efficiency are achieved. When the downward pressing component 21 starts to work, it can punch holes in the copper bar 100 according to the preset pressure and stroke, so that the copper bar 100 forms holes that meet the requirements; under the action of the switching component 22, the downward pressing component 21 can be converted into a cutting mode to cut the copper bar 100 into different specified lengths. The whole process is coherent and smooth, reducing the time cost of replacing equipment.

[0044] Further, as Figures 3 to 5 shown, the downward pressing component 21 includes: A pressing and cutting machine body 211, which is provided with a chute and an inclined chute for discharging the waste generated by pressing and cutting; A hydraulic cylinder 212, which is installed on the pressing and cutting machine body 211; A pressing block 213, which is arranged on the ejector rod of the hydraulic cylinder 212; Copper bar conveying wheels 214, which are arranged on the pressing and cutting machine body 211 and are used for conveying and supporting the copper bar 100; A waste collection box 215, which is arranged on the pressing and cutting machine body 211 and is used for collecting the waste generated by pressing and cutting.

[0045] In this embodiment, by setting the downward pressing component 21, the operations of punching holes and cutting the copper bar 100 are realized, and the copper bar 100 is cut into different specified lengths. The whole process is coherent and smooth, reducing the time cost of replacing equipment, and the waste can be stably and properly collected and processed.

[0046] Specifically, when the copper bar 100 needs to be processed, the hydraulic cylinder 212 starts to work, and the ejector rod of the hydraulic cylinder 212 pushes the pressing block 213 to move downward. According to the operation mode selected by the switching component 22, if it is the punching hole mode, the pressing block 213 will carry the corresponding punching hole die to apply pressure to the copper bar 100 to punch holes in the copper bar 100. Since a chute is provided on the pressing and cutting machine body 211, the pressing block 213 can move up and down stably under the restriction of the chute, ensuring the accuracy of the punching hole position. The waste generated during the punching hole process will slide down along the inclined chute on the pressing and cutting machine body 211 into the waste collection box 215, realizing the automatic collection of waste, keeping the working area clean, and avoiding the accumulation of waste affecting the processing operation.

[0047] If the cutting mode is selected by the switching component 22, the pressing block 213 will carry a cutting tool to cut the copper bar 100. At this time, the copper bar conveying wheel 214 plays an important role. On the one hand, it supports the copper bar 100 to keep the copper bar 100 stable during the cutting process. By controlling the stroke and pressure of the ejector rod of the hydraulic cylinder 212, the cutting depth and strength can be accurately controlled to ensure that the length of the cut copper bar meets the production requirements.

[0048] Further, as Figures 5 to 7 shown, the switching component 22 includes: A fixed rod 221, which is arranged on the pressing and cutting body 211; A sliding seat 222, which is sleeved on the fixed rod 221; A first sliding rod 223, which is arranged inside the sliding seat 222; A first lead screw 224; A slider 225, which is sleeved on the first sliding rod 223 and the first lead screw 224, and a variety of pressing blocks 2251 are arranged on the slider 225; A first motor 226, the output shaft of which is in transmission connection with the first lead screw 224; A driven rod 227, which is arranged on the sliding seat 222 and is also inserted into a through groove on the sliding pressing base 228 to drive the sliding pressing base 228 to move; A sliding pressing base 228, on which a circular groove for mating with the pressing hole and a groove for cutting are provided; A limiting rod 229, which is arranged on the sliding seat 222 and passes through the pressing block 213 to drive the sliding seat 222 to move upward through the pressing block 213.

[0049] In this embodiment, by setting the switching component 22, it can be flexibly switched between the two operation modes of pressing holes and cutting, so as to meet the different processing requirements of copper bars in the production of composite busbars and improve the production efficiency.

[0050] Specifically, when it is necessary to switch the processing mode, the output shaft of the first motor 226 drives the first lead screw 224 to rotate. The first lead screw 224 is in threaded cooperation with the slider 225, and the slider 225 is also sleeved on the first sliding rod 223. This makes the slider 225 have a stable guide during the movement and will not shake randomly, ensuring that the pressing blocks 2251 installed on the slider 225 can accurately move to the specified positions. Different pressing blocks 2251 respectively correspond to the functions of pressing holes and cutting, so that the processing method can be switched according to the production requirements.

[0051] The follower rod 227 cooperates with the sliding seat 222 and the sliding pressing and cutting base 228. The follower rod 227 is arranged on the sliding seat 222 and inserted into the through groove of the sliding pressing and cutting base 228. When the sliding seat 222 moves along with the slider 225, the follower rod 227 moves accordingly, thereby driving the sliding pressing and cutting base 228 to move. When performing the hole pressing operation, the circular groove on the sliding pressing and cutting base 228 that cooperates with the hole pressing moves to the position corresponding to the copper bar and the pressing block; during cutting, the cutting groove moves to the corresponding position to ensure the accurate progress of the processing operation.

[0052] The limiting rod 229 cooperates with the pressing block 213 and the sliding seat 222. The limiting rod 229 is arranged on the sliding seat 222 and penetrates through the pressing block 213. When the pressing block 213 moves upward after completing the downward pressing action, the limiting rod 229 will be driven by the pressing block 213, so that the sliding seat 222 also moves upward, enabling the switching component 22 to return to the initial state and making preparations for the next switching, ensuring the coherence and automation of the switching process.
