[0100] Embodiment one

[0101] As shown in Figure 1 and Figures 8 to 12 , the present embodiment provides a composite busbar production line for new energy vehicles, comprising a bidirectional bending mechanism 3, the bidirectional bending mechanism 3 comprises:

[0102] A translation assembly 31 is arranged on the conveying belt 200, a clamping assembly 32 for clamping the copper bar 100 is arranged on the translation assembly 31, a fixing assembly 33 for fixing the bending position of the copper bar 100 is arranged below the clamping assembly 32, and a bending assembly 34 which can adjust the bending position is arranged.

[0103] When bending the two ends of copper bars of different lengths, the clamping assembly 32 clamps the copper bar 100 from the previous work station, and drives the copper bar 100 to move to the appropriate position by the translation assembly 31, the fixing assembly 33 fixes the copper bar 100 at the position where the copper bar 100 needs to be bent, the bending assembly 34 moves to the bending position following the fixing assembly 33, and the bending assembly 34 bends the copper bar 100 to the required angle.

[0104] In the embodiment, the translation assembly 31, the clamping assembly 32, the fixing assembly 33 and the bending assembly 34 in the bidirectional bending mechanism 3 cooperate with each other to realize the function of simultaneously bending the two ends of the copper bars 100 of different lengths, thereby improving the bending efficiency, ensuring the stability of the copper bars 100 during the bending process, and precisely controlling the bending position. The translation assembly 31 drives the copper bars 100 to move, transfers the copper bars 100 from the shearing mechanism 2 to the bending position, and then transfers the copper bars 100 to the conveyor belt 200 after the bending is completed. The clamping assembly 32 firmly clamps the copper bars 100 to prevent displacement of the copper bars 100 during movement and bending. The fixing assembly 33 precisely positions the bending position of the copper bars 100 to ensure that each bending can meet the expected position requirements. The bending assembly 34 bends the copper bars 100 according to the position determined by the fixing assembly 33 to realize the bending forming of the copper bars 100.

[0105] Further, as shown in Figures 8 to 9 the translation assembly 31 comprises:

[0106] a support frame 311 provided on the conveyor belt 200;

[0107] a second sliding rod 312 provided on the support frame 311;

[0108] a second lead screw 313 provided on the support frame 311;

[0109] a moving seat 314 sleeved on the second sliding rod 312 and the second lead screw 313;

[0110] a second motor 315 in transmission connection with the second lead screw 313;

[0111] a third sliding rod 316 provided on the moving seat 314;

[0112] a sliding mounting seat 317 sleeved on the third sliding rod 316;

[0113] a first electric push rod 318, the top rod of which is connected with the sliding mounting seat 317 for changing the position of the sliding mounting seat 317.

[0114] In the embodiment, by providing the translation assembly 31, the copper bars 100 of different sizes sheared by the shearing mechanism 2 can be transferred to the bending position, and then transferred to the conveyor belt 200 for collection after the bending is completed.

[0115] In detail, the second motor 315 drives the second screw rod 313 to rotate, and the moving seat 314 moves along the direction of the second sliding rod 312, the second sliding rod 312 plays a guiding role to ensure the stable movement of the moving seat 314, and the moving seat 314 can accurately drive the upper part to move to the required position, facilitating subsequent operations such as bending of the copper bar 100. When the first electric push rod 318 works, the top rod of the first electric push rod 318 extends and retracts, pushes or pulls the sliding mounting seat 317, and the third sliding rod 316 provides support and guidance for the movement of the sliding mounting seat 317. In this way, the position of the clamping assembly 32 can be flexibly adjusted according to the actual situation of the copper bar 100, the movement track is prevented from being blocked, and the clamping assembly 32 can accurately clamp the copper bar 100, thereby improving the accuracy and stability of production.

[0116] Further, as shown in Figures 8 to 9 , the clamping assembly 32 comprises:

[0117] The fixed clamping plate 321 is arranged on the sliding mounting seat 317.

[0118] The second electric push rod 322 is arranged on the sliding mounting seat 317.

[0119] The pressing plate 323 is connected with the top rod of the second electric push rod 322, and is used for clamping the copper bar 100 together with the fixed clamping plate 321.

[0120] In this embodiment, the clamping assembly 32 is arranged to realize the clamping function of the copper bar 100, so that the copper bar 100 can be kept stable during movement and bending, and displacement is avoided.

[0121] In detail, when the copper bar 100 needs to be clamped, the second electric push rod 322 is started, the top rod of the second electric push rod 322 extends, the top rod pushes the pressing plate 323 connected thereto, 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 keeps still, the pressing plate 323 gradually approaches the fixed clamping plate 321, until the copper bar 100 is tightly clamped between the two, and the copper bar 100 is located in the middle of the two. The advantage of this design is that the second electric push rod 322 can provide stable and adjustable pushing force, so that the pressing plate 323 can flexibly adjust the clamping force according to the thickness of the copper bar 100, the fixed clamping plate 321 provides a stable support surface for the copper bar 100, and the pressing plate 323 and the fixed clamping plate 321 work together to firmly clamp the copper bar 100, so that the copper bar 100 will not shake or deviate during subsequent translation, bending and other operations, and the accuracy of processing is ensured.

[0122] Further, as shown in Figures 10 to 12 , the clamping assembly 32 comprises:

[0123] a mounting base 331;

[0124] a fourth slide bar 332, disposed on the mounting base 331;

[0125] a first bidirectional screw rod 333, disposed on the mounting base 331;

[0126] a third motor 334, the output shaft of which is in driving connection with the first bidirectional screw rod 333;

[0127] a sliding frame 335, sleeved on the fourth slide bar 332 and the first bidirectional screw rod 333, and symmetrically arranged;

[0128] a fifth slide bar 336, disposed inside the sliding frame 335;

[0129] a second bidirectional screw rod 337;

[0130] a fourth motor 338, the output shaft of which is in driving connection with the second bidirectional screw rod 337;

[0131] a fixed pressing plate 339, sleeved on the fifth slide bar 336 and the second bidirectional screw rod 337, and symmetrically arranged.

[0132] In the embodiment, the fixed assembly 33 is arranged to realize the precise fixing function of the bending position of the copper bar 100, so as to ensure that the bending assembly 34 can perform bidirectional bending operation on the copper bar 100 at the accurate position, and improve the bending precision and stability.

[0133] 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 screw rod 333 to rotate, and the two sliding frames 335 move relatively or oppositely 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 adapt to the fixing requirement of copper bars 100 of different sizes, and the fourth slide bar 332 plays a guiding role to ensure the stable movement of the sliding frame 335;

[0134] Then, the fourth motor 338 is started, the second bidirectional screw rod 337 is driven to rotate, and the two fixed pressing plates 339 are relatively moved along the direction of the fifth slide rod 336, so that the copper bar 100 is tightly fixed between the two fixed pressing plates 339, the bending position of the copper bar 100 is fixed, and the fifth slide rod 336 also plays a guiding role to ensure that the fixed pressing plate 339 stably fixes the copper bar 100. This design can accurately adjust the fixed position, and no matter how the length of the copper bar 100 changes, stable and accurate fixing can be realized, which provides reliable guarantee for the subsequent bending process.

[0135] Further, as shown in Figures 10 to 12 the bending assembly 34 comprises:

[0136] The telescopic rod 341 is arranged on the mounting bottom plate 331.

[0137] The slide rail 342 is arranged on the top rod of the telescopic rod 341.

[0138] The hydraulic rod 343 is arranged on the mounting bottom plate 331, and the top rod is connected with the slide rail 342.

[0139] The sliding seat 344 is arranged on the slide rail 342.

[0140] The support plate 345 is arranged on the sliding seat 344.

[0141] The bending plate 346 is arranged on the support plate 345.

[0142] The connecting plate 347 is arranged on the support plate 345.

[0143] The fixed plate 348 is arranged on the sliding frame 335.

[0144] The sliding rod 349 is arranged on the fixed plate 348 and is inserted into the connecting plate 347 to drive the bending plate 346 to move.

[0145] In this embodiment, by arranging the bending assembly 34, the bending assembly 34 moves together with the fixing assembly 33, can accurately bend the copper bar 100 after the copper bar 100 is fixed by the fixing assembly 33, realizes efficient processing of the copper bar 100, and improves production efficiency and product quality.

[0146] In detail, after 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 extension and retraction amount of the top rod of the hydraulic rod 343, the sliding seat 344 can be moved above the bending area of the copper bar 100 along the slide rail 342. When the bending operation is needed, the top rod of the hydraulic rod 343 retracts, driving the slide rail 342 to descend, and then the bending plate 346 mounted on the support plate 345 gradually approaches and contacts the copper bar 100. With the hydraulic rod 343 continuing to apply pressure, the bending plate 346 bends the copper bar 100 to a set angle. In the whole process, the sliding rod 349 closely cooperates with the connecting plate 347. Since the fixed 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 bending or bending at different angles of the copper bar 100, the action of the hydraulic rod 343 and the position of the sliding frame 335 are adjusted again to realize flexible and variable two-way bending operation.

[0147] Further, as shown in Figures 1 to 2 , further comprising:

[0148] The copper bar conveying mechanism 1 comprises:

[0149] The copper bar conveying mechanism 1 comprises:

[0150] The base 102;

[0151] The conveying rollers 103 are rotatably arranged on the base 102, and a rubber sleeve for pressing the copper bar 100 is sleeved on the conveying rollers 103;

[0152] The pulley 104 is in transmission connection with the conveying roller 103;

[0153] The transmission belt 105 is used to connect a plurality of pulleys 104;

[0154] The output shaft of the conveying motor 106 is in transmission connection with the conveying roller 103.

[0155] 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 process of the production line. In cooperation with the pressing and cutting mechanism 2, the pressing and cutting hole operation is performed at a suitable position, and the copper bar 100 is pressed and cut into copper bars 100 of different sizes.

[0156] In detail, when the composite busbar production line starts, the copper bar conveyor 101 starts to work and gradually releases the copper bar 100 in a roll or bundle. At this time, the conveying motor 106 is powered on and runs, and its output shaft drives the conveying rollers 103 connected thereto to rotate. Since the plurality of conveying rollers 103 are connected to each other through the belt pulley 104 and the transmission belt 105, all the conveying rollers 103 will rotate synchronously under the drive of the conveying motor 106. The rubber sleeve sleeved on the conveying roller 103 plays a crucial role. It not only increases the friction between the copper bar 100 to ensure that the copper bar 100 does not slip during conveying, but also avoids direct hard contact between the conveying roller 103 and the copper bar 100 to prevent scratches on the surface of the copper bar 100, thereby ensuring accurate control of the output of the copper bar 100.

[0157] With the continuous rotation of the conveying roller 103, the copper bar 100 is stably and quantitatively conveyed forward under the action of friction. By controlling the rotating speed of the conveying 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 bidirectional bending mechanism 3. When the pressing and cutting mechanism 2 performs hole pressing or cutting operation, the conveying motor 106 stops rotating to ensure that the copper bar 100 remains stable during the pressing and cutting process.

[0158] Further, as shown in Figures 3 to 7 , the pressing and cutting mechanism 2 comprises:

[0159] a pressing assembly 21 for pressing holes and cutting the copper bar 100 to the required length;

[0160] a switching assembly 22 arranged on the pressing assembly 21 and used for switching the hole pressing or cutting operation of the copper bar 100.

[0161] In this embodiment, through the cooperative work of the pressing assembly 21 and the switching assembly 22, the function of diversifying the processing of the copper bar 100 is realized, thereby meeting different production needs and improving production efficiency. When the pressing assembly 21 starts to work, it can press holes in the copper bar 100 according to the preset pressure and stroke, so that the copper bar 100 forms holes meeting the requirements. Under the action of the switching assembly 22, the pressing assembly 21 can be converted into a cutting mode to cut the copper bar 100 into different lengths. The whole process is smooth and coherent, reducing the time cost of replacing equipment.

[0162] Further, as shown in Figures 3 to 5 , the pressing assembly 21 comprises:

[0163] a pressing and cutting body 211 provided with a chute and an inclined groove for discharging the waste generated by pressing and cutting;

[0164] A hydraulic cylinder 212 is mounted on the press-cutting machine body 211.

[0165] A pressing block 213 is arranged on the ejector rod of the hydraulic cylinder 212.

[0166] A copper bar conveying wheel 214 is arranged on the press-cutting machine body 211 and used for conveying and supporting the copper bar 100.

[0167] A waste collecting box 215 is arranged on the press-cutting machine body 211 and used for collecting the waste generated by the press-cutting.

[0168] In the embodiment, the press-cutting machine body 211 is provided with the pressing assembly 21, so that the press-cutting operation is realized on the copper bar 100, the copper bar 100 is cut into different lengths, the whole process is smooth and continuous, the time cost of replacing the equipment is reduced, and the waste can be properly collected and treated.

[0169] Specifically, when the copper bar 100 needs to be processed, the hydraulic cylinder 212 starts to work, 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 assembly 22, if the hole pressing mode is selected, the pressing block 213 will carry the corresponding hole pressing die to press the copper bar 100, and a hole is pressed on the copper bar 100. Since the sliding groove is arranged on the press-cutting machine body 211, the pressing block 213 can stably move up and down under the limitation of the sliding groove, so as to ensure the accuracy of the hole pressing position. The waste generated during the hole pressing process will slide along the inclined groove on the press-cutting machine body 211 and fall into the waste collecting box 215, so as to realize the automatic collection of the waste, keep the working area clean, and avoid the accumulation of the waste affecting the processing operation.

[0170] If the cutting mode is selected by the switching assembly 22, the pressing block 213 will carry the cutting tool to cut the copper bar 100. The copper bar conveying wheel 214 plays an important role at this time, which supports the copper bar 100 and keeps 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 intensity can be accurately controlled, so as to ensure that the length of the cut copper bar meets the production requirements.

[0171] Further, as shown in the drawings, the switching assembly 22 comprises: Figures 5 to 7 A fixed rod 221 is arranged on the press-cutting machine body 211.

[0172] A sliding seat 222 is sleeved on the fixed rod 221.

[0173] A first sliding rod 223 is arranged in the sliding seat 222.

[0174] ​

[0175] First lead screw 224;

[0176] The slider 225 is sleeved on the first slide rod 223 and the first lead screw 224, and the slider 225 is provided with a variety of cutting blocks 2251;

[0177] The first motor 226, the output shaft of the first motor 226 is connected to the first lead screw 224 in a transmission connection;

[0178] Driven rod 227 is disposed on the sliding seat 222 and is also inserted into the through groove on the sliding cutting base 228 to drive the sliding cutting base 228 to move;

[0179] A sliding pressure-cutting base 228 is provided with a circular groove for mating pressure holes and a cutting groove.

[0180] A limiting rod 229 is disposed on the sliding seat 222 and passes through the pressure block 213 so that the sliding seat 222 can be moved upward by the pressure block 213.

[0181] In this embodiment, by setting the switching component 22, it is possible to flexibly switch between the two operation modes of pressing holes and cutting, thereby meeting the different processing requirements of copper busbars in the production of composite busbars and improving production efficiency.

[0182] In detail, 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 threadedly engaged with the slider 225, and the slider 225 is sleeved on the first slide rod 223. This makes the slider 225 have stable guidance during movement and will not shake randomly. This ensures that the pressure cutting block 2251 installed on the slider 225 can move accurately to the designated position. Different pressure cutting blocks 2251 correspond to the pressing and cutting functions respectively, so that the processing mode can be switched according to production needs.

[0183] The driven rod 227 cooperates with the sliding seat 222 and the sliding cutting base 228. The driven rod 227 is set on the sliding seat 222 and inserted into the through groove of the sliding cutting base 228. When the sliding seat 222 moves with the slider 225, the driven rod 227 moves accordingly, thereby driving the sliding cutting base 228 to move. When the pressing operation is performed, the circular groove on the sliding cutting base 228 that matches the pressing hole moves to the position corresponding to the copper busbar and the pressing block. When cutting, the cutting groove moves to the corresponding position to ensure that the processing operation is carried out accurately.

[0184] The limiting rod 229 cooperates with the pressure block 213 and the sliding seat 222. The limiting rod 229 is set on the sliding seat 222 and passes through the pressure block 213. When the pressure block 213 completes the downward pressing action and moves upward, the limiting rod 229 will be driven by the pressure block 213, thereby causing the sliding seat 222 to also move upward, allowing the switching component 22 to return to the initial state and prepare for the next switching, ensuring the continuity and automation of the switching process.
