Description

Technical Field

[0001] This invention relates to the field of photovoltaic cell technology, and in particular to a ribbon cutting device and an array welding machine. Background Technology

[0002] Solar cell modules are the core component of a solar photovoltaic system. Their function is to convert sunlight into electrical energy, outputting direct current (DC) which is then stored in a battery. Specifically, under sunlight, solar cell modules generate an electromotive force (EMF). These modules are connected in series and parallel to form a solar cell array, ensuring the array voltage meets the system's input voltage requirements. A charge / discharge controller then charges the battery, storing the electrical energy converted from sunlight.

[0003] Solar cell modules are typically manufactured using string bonding equipment. During production, multiple cells are strung together using tin-plated copper strips (i.e., solder strips). To facilitate connecting the cells in series via the solder strips, the strips need to be cut to the required dimensions. If the relative positions of the upper and lower cutters cannot be adjusted during the use of the solder strip cutting device, the cutting quality of the solder strips can be affected. Summary of the Invention

[0004] The first aspect of the present invention provides a welding strip shearing device that solves the problem that the relative positions of the upper and lower cutters cannot be adjusted and matched. The device can adjust the position of the first or second cutter in a timely manner, so that the spacing or parallelism between the first and second cutters can be adjusted accordingly, ensuring neat welding strip shearing and improving welding strip processing efficiency.

[0005] A second aspect of the present invention provides an array welding machine.

[0006] A first aspect of the present invention provides a welding strip shearing device, comprising:

[0007] The first shearing mechanism includes at least one set of first shearing components, each set of first shearing components including a first cutter;

[0008] A second shearing mechanism is disposed opposite to the first shearing mechanism. The second shearing mechanism includes a shearing drive component and a second shearing assembly. The number of the second shearing assemblies is adapted to the number of the first shearing assemblies. The second shearing assembly includes a second cutter. The shearing drive component is used to drive the second cutter to move closer to or further away from the first cutter. The position of at least one of the first cutter and the second cutter is adjustable.

[0009] A second aspect of the present invention provides an array welding machine, comprising a pre-pressing device for the welding strip, a post-pressing device for the welding strip, and a welding strip cutting device as described in any one of the present invention;

[0010] Along the conveying direction of the welding strip, the welding strip front pressing device, the welding strip rear pressing device, and the welding strip shearing device are arranged in sequence.

[0011] The welding strip shearing device provided by this invention allows for adjustment of the position of at least one of the first and second cutters. During use, if the relative positions of the vertically opposed first and second cutters do not align, the position of either the first or second cutter can be adjusted promptly. This allows for corresponding adjustment of the spacing or parallelism between the first and second cutters, ensuring neat welding strip shearing and improving welding strip processing efficiency.

[0012] The array welding machine provided by the present invention has all the advantages described above because it includes the above-mentioned welding strip cutting device. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0051] See Figure 1 and Figure 2 This invention provides a welding strip processing device for shaping, flattening, and shearing welding strips. The device includes a welding strip pre-pressing device 400, a welding strip post-pressing device 500, a welding strip shearing device 600, and a traction device 800, sequentially arranged along the welding strip's transport direction on a receiving member 1000. Since the welding strip needs to be dipped in flux before the pre-pressing device 400, residual flux drips as the welding strip passes through the processing device. The receiving member 1000 collects the flux carried on the welding strip, preventing it from dripping onto the corresponding drive components and affecting their operation.

[0052] The welding strip pre-pressing device 400 includes a pre-pressing mechanism 430 and a pre-pressing translation mechanism 410. The output end of the pre-pressing translation mechanism 410 is connected to the pre-pressing mechanism 430 and is used to drive the pre-pressing mechanism 430 to perform linear reciprocating motion. The pre-pressing mechanism 430 is used to press the welding strip, and under the driving action of the pre-pressing translation mechanism 410, the welding strip undergoes plastic deformation and is in a taut state, preventing the welding strip from bending and affecting subsequent welding processes.

[0053] The welding strip pressing device 500 includes a pressing body 520, a pressing mechanism 530, and a flattening mechanism 540. Both the pressing mechanism 530 and the flattening mechanism 540 are located within the pressing body 520. The pressing mechanism 530 is used to press the welding strip, and the flattening mechanism 540 is used to flatten the welding strip. A welding strip cutting device 600 is used to cut the welding strip; a traction device 800 is used to traction the welding strip to transport it to a preset position.

[0054] In the strip processing, the strip is first clamped by the traction device 800 and pulled to a first preset position. At this first preset position, the strip pressing device 400 presses the strip tightly. The pressing translation mechanism 410 drives the strip pressing device 400 to move backward, causing the strip to undergo plastic deformation and become taut. Then, the flattening mechanism 540 flattens the strip. After that, the pressing device 400 releases the pressure on the strip, and the traction device 800 pulls the strip to a second preset position. At this second preset position, the strip shearing device 600 shears the strip to complete the processing of the target length. This process can simultaneously process multiple sets of strips for shaping, flattening, and shearing, resulting in high processing efficiency.

[0055] It is understood that the welding strip processing equipment provided in this embodiment of the invention, by setting a traction device 800, enables the traction device 800, the welding strip front pressing device 400, the welding strip rear pressing device 500, and the welding strip cutting device 600 to jointly participate in the welding strip processing process, which can effectively improve the welding strip processing efficiency. That is, in the welding strip processing process, the welding strip is first clamped by the traction device 800 and pulled to a first preset position. At the first preset position, the welding strip front pressing device 400 presses the welding strip. The front pressing translation mechanism 410 drives the welding strip front pressing device 400 to move backward, so that the welding strip undergoes plastic deformation and becomes taut. Then, the flattening mechanism 540 flattens the welding strip. Then, the welding strip front pressing device 400 releases the pressing effect on the welding strip, and the traction device 800 pulls the welding strip to a second preset position. At the second preset position, the welding strip cutting device 600 cuts the welding strip to complete the processing of the welding strip to the target length. This process can simultaneously process, shape, flatten, and shear multiple sets of weld strips, resulting in high processing efficiency.

[0056] Furthermore, the welding strip post-pressing device 500 also includes a post-pressing translation mechanism 510, which includes a post-pressing drive component 511 and a post-pressing guide component 512. The post-pressing body 520 is guided and cooperates with the post-pressing guide component 512, and the output end of the post-pressing drive component 511 is fixedly connected to the post-pressing body 520. After the welding strip is pressed by the welding strip post-pressing device 500, under the driving action of the post-pressing translation mechanism 510, the welding strip is moved towards the direction of the welding strip cutting device 600, so that the end of the welding strip is exposed at the cutting position of the welding strip cutting device 600, which is convenient for the traction device to clamp.

[0057] During the strip processing, the strip is first clamped by the traction device 800 and pulled to a first preset position. At this first preset position, the strip front pressing device 400 presses the strip. The strip front pressing device 400 is driven to move backward by the front pressing translation mechanism 410, so that the strip undergoes plastic deformation and becomes taut. At the same time, the strip rear pressing translation mechanism 510 drives the strip rear pressing device 500 to move back to the initial position, in preparation for the next transfer of the strip to expose the cutting position of the strip cutting device 600. Since the strip tautness and the strip rear pressing device 500 reset are driven by different driving components and can be performed simultaneously, time can be saved and the strip processing efficiency can be further improved.

[0058] See Figure 3 and Figure 4 The welding strip pre-pressing device 400 provided in this embodiment of the invention includes a pre-pressing body 420 and a pre-pressing mechanism 430. The pre-pressing body 420 serves as the skeleton of the welding strip pre-pressing device 400 and is used to support the corresponding components of the welding strip pre-pressing device 400. That is, the pre-pressing mechanism 430 is located on the pre-pressing body 420.

[0059] The front pressure mechanism 430 includes a pressure-bearing component 431, at least two sets of front pressure components 432, and an air supply component 433 corresponding to the number of front pressure components 432. Each set of front pressure components 432 cooperates with the pressure-bearing component 431 to press the corresponding welding strip. Each set of air supply components 433 is used to supply air to the corresponding front pressure component 432. Adjacent air supply components 433 are spaced apart or staggered. Each set of air supply components 433 is independently connected to an air source.

[0060] That is, the minimum number of front pressure components 432 is set to two, and the number of front pressure components 432 can be determined according to the number of welding strips. For example, when the string welding equipment simultaneously strings three sets of battery strings, the number of front pressure components 432 is set to three, and the three sets of front pressure components 432 are arranged at equal intervals.

[0061] It is understood that the welding strip pre-pressing device 400 provided in this embodiment of the invention, by setting at least two sets of pre-pressing components 432 and air supply components 433 corresponding to the number of pre-pressing components 432, allows each set of air supply components 433 to supply air to the corresponding pre-pressing components 432. Adjacent air supply components 433 are spaced apart or staggered, and each set of air supply components 433 is independently connected to an air source. In this way, by dividing the overall air supply device into multiple sets of air supply components 433 and improving the layout and structure of the corresponding air supply components 433, so that each set of air supply components 433 is independently connected to an air source, the flow path of the supply airflow and the outlet airflow can be shortened, the loss of the corresponding airflow can be reduced, the air source of the air supply components 433 can be ensured to be stable, and the air supply components 433 can be ensured to move synchronously. This allows each set of pre-pressing components 432 to be pressed synchronously, which can make the welding strip processing process smoother while improving the welding strip processing efficiency.

[0062] See Figures 5 to 7 In some embodiments of the present invention, each air supply assembly 433 includes a rectangular air supply body 4331 and multiple connectors 4332 located on both sides of the air supply body 4331. The internal structure of the air supply body 4331 includes an air inlet channel 4331-1 and an air outlet channel 4331-2, that is, an air inlet channel 4331-1 and an air outlet channel 4331-2 are provided through the air supply body 4331 along its length direction. The virtual axes of the air inlet channel 4331-1 and the air outlet channel 4331-2 are projected onto the horizontal plane to facilitate the connection of the air source.

[0063] On both sides of the air supply body 4331, there are multiple air inlet ports 4331-3 communicating with the air inlet channel 4331-1, and multiple air outlet ports 4331-4 communicating with the air outlet channel 4331-2. The air inlet channel 4331-1 and the air outlet channel 4331-2 are connected to the air source through solenoid valves, and the pre-pressure assembly 432 is connected to the air inlet ports 4331-3 and the air outlet ports 4331-4 through corresponding connectors 4332.

[0064] Essentially, the air supply unit 4331 functions similarly to a distributor, ensuring that the airflow entering the intake channel 4331-1 from the air source is evenly distributed through multiple intake ports 4331-3 before entering the corresponding pre-pressure components 432. This achieves uniform and equal air supply to the corresponding pre-pressure components 432, optimizing the air supply performance of the air supply components 433 and achieving synchronous air supply, thus realizing the synchronous compression of the pre-pressure components 432. The air outlet principle is similar to the air supply principle and will not be elaborated here.

[0065] See details Figure 7 In some embodiments of the invention, the inner diameter of the air inlet 4331-3 is smaller than the inner diameter of the air inlet channel 4331-1, which is equivalent to a reduction in the airflow area. According to the Venturi effect, the gas velocity is inversely proportional to the cross-sectional area. Therefore, the reduced cross-sectional area from the air inlet channel 4331-1 to the air inlet 4331-3 increases the airflow velocity, thereby improving the response efficiency of the pre-pressure assembly 432. Conversely, the inner diameter of the air outlet 4331-4 is smaller than the inner diameter of the air outlet channel 4331-2, which is equivalent to an increased airflow area and a reduced airflow velocity. This allows the pre-pressure assembly 432 to release the pressure on the welding strip more smoothly.

[0066] Continue reading Figures 3 to 5 In some embodiments of the present invention, one end of the air intake channel 4331-1 and the air outlet channel 4331-2 is blocked, and the other end of the air intake channel 4331-1 and the air outlet channel 4331-2 is connected to the air source through a solenoid valve. In this case, it is equivalent to connecting the air source to one end of the air supply body 4331 and blocking the other end of the air supply body 4331.

[0067] Alternatively, both ends of the air inlet channel 4331-1 and the air outlet channel 4331-2 can be connected to the air source via solenoid valves. This is equivalent to connecting the air source to both ends of the air supply body 4331 simultaneously, allowing air to enter and exit at both ends of the air supply body 4331 at the same time. The specific connection method can be determined according to the application scenario of the welding strip pre-pressing device 400.

[0068] Continue reading Figure 3 and Figure 4 And see also Figure 8 In some embodiments of the present invention, the pressure-bearing component 431 includes a plate-shaped pressure-bearing base 4311 and a strip-shaped baffle 4312. The baffle 4312 is fixedly connected to the upper surface of the pressure-bearing base 4311 by fasteners such as screws and bolts. A limiting gap 4313 for the welding strip to pass through is formed between the baffle 4312 and the pressure-bearing base 4311.

[0069] Essentially, the side surface of the baffle 4312 facing the pressure-bearing substrate 4311 is recessed inward to form a groove, and the two ends of the baffle 4312 abut against the upper surface of the pressure-bearing substrate 4311. A limiting gap 4313 is formed between the bottom wall of the groove and the upper surface of the pressure-bearing substrate 4311. When the welding strip passes through the limiting gap 4313, the bottom wall of the groove and the upper surface of the pressure-bearing substrate 4311 respectively restrict the welding strip from moving upward and downward, thus preventing the welding strip from swinging.

[0070] In addition, a plurality of first limiting members 4314 are arrayed on the pressure-bearing substrate 4311. The first limiting member 4314 can be a columnar structure integrally formed with the pressure-bearing substrate 4311, or it can be a pin. A limiting groove (not labeled in the figure) for limiting the welding strip is provided between two adjacent first limiting members 4314. That is, two adjacent first limiting members 4314 cooperate to limit the movement of the welding strip to the left or right. Each first limiting member 4314 is located in the limiting gap 4313 or abuts against the baffle 4312.

[0071] Essentially, by restricting the upward and downward movement of the welding strip through the bottom wall of the groove and the upper surface of the pressure-bearing base 4311 respectively, the welding strip can be stably transported along the transmission direction by the cooperation of two adjacent first limiting members 4314 to restrict the left and right movement of the welding strip, thus avoiding the welding strip shaking or misalignment, which would affect the further processing of the welding strip.

[0072] Continue reading Figure 3 and Figure 4 In some embodiments of the present invention, the pre-pressing assembly 432 includes a plurality of pre-pressing cylinders 4321 arranged in an array. The plurality of pre-pressing cylinders 4321 are respectively disposed on both sides of the air supply assembly 433, and each pre-pressing cylinder 4321 corresponds to one welding strip. That is, each welding strip is compressed by its corresponding pre-pressing cylinder 4321. By controlling the air supply of the pre-pressing cylinder 4321, the degree of compression of the welding strip by the pre-pressing cylinder 4321 can be adjusted.

[0073] It should be noted that the welding strip front pressing device 400 provided in this embodiment of the invention uses a front pressing cylinder 4321 to press a corresponding welding strip. Of course, a cylinder can also be used to drive the pressing component to move so that the pressing component presses each welding strip synchronously. The pressing component may include a pressure plate, a pressure rod and a spring. The pressure rod is movably connected to the pressure plate, and the spring is sleeved on the pressure rod. One end of the spring abuts against the pressure plate, and the other end of the spring abuts against the end of the pressure rod. The pressure plate is driven to move by the cylinder, thereby driving the pressure plate to move to achieve welding strip pressing.

[0074] Continue reading Figure 3 and Figure 4In some embodiments of the present invention, the front pressure mechanism 430 further includes a front pressure bracket 434, which is detachably connected to the front pressure body 420. The front pressure bracket 434 and the front pressure body 420 are supported by multiple support components 460. The air supply components 433 are all fixedly installed on the front pressure bracket 434. With this arrangement, the front pressure bracket 434 and the front pressure body 420 cooperate to form multiple gantry structures, and the air supply components 433 are set in the corresponding gantry structures, resulting in better structural stability.

[0075] The front pressure bracket 434 serves as the mounting frame for the front pressure mechanism 430, and is used to install the air supply component 433 and the front pressure component 432. The front pressure mechanism 430 is detachably connected to the front pressure body 420 through the front pressure bracket 434 to facilitate the disassembly of each component.

[0076] Specifically, the front pressure bracket 434 and the front pressure body 420 are rotatably connected by a first hinge shaft 440, and one end of the first hinge shaft 440 extending out of the front pressure body 420 or the front pressure bracket 434 is limited by a limiting component 450.

[0077] Continue reading Figure 3 In some embodiments of the present invention, the welding strip pre-pressing device 400 further includes a pre-pressing translation mechanism 410, which includes a pre-pressing drive component 411 and a pre-pressing guide component 412. The pre-pressing body 420 is fixedly connected to the output end of the pre-pressing drive component 411 and is guided and cooperated with the pre-pressing guide component 412.

[0078] The front pressure guide component 412 includes a slidingly fitted front pressure guide rail 4121 and a front pressure slider 4122. The front pressure guide rail 4121 is fixedly connected to the mounting base 521, and the front pressure slider 4122 is fixedly connected to the front pressure machine body 420. When the welding strip is clamped and pulled to a first preset position by the traction device 800, at the first preset position, the front pressure component 432 presses the welding strip, and the front pressure drive component 411 drives the front pressure component 432 to move along the extension direction of the front pressure guide rail 4121, causing the welding strip to move backward to produce plastic deformation and tighten it.

[0079] Among them, the front pressure drive component 411 is a linear drive component, such as a linear motor, cylinder, electric cylinder, etc. It can also be a synchronous belt linear module or a ball screw linear module, etc. Any component that can achieve linear motion is acceptable.

[0080] See Figures 9 to 12 The welding strip post-pressing device 500 provided in this embodiment of the invention mainly includes a post-pressing body 520, a post-pressing mechanism 530, and a flattening mechanism 540.

[0081] The overall structure of the rear press body 520 is gantry-type, mainly used to provide support for the rear press mechanism 530 and the flattening mechanism 540, serving as the skeleton of the welding strip rear press device 500 and supporting the corresponding components of the welding strip rear press device 500. The rear press mechanism 530 is located in the rear press body 520 and is used to press the welding strip.

[0082] The flattening mechanism 540 includes a pressure platform 541, multiple sets of flattening drive assemblies 542, and flattening assemblies 543 corresponding to the number of flattening drive assemblies 542. The pressure platform 541 is located on the rear press body 520, and the multiple sets of flattening drive assemblies 542 are arrayed on both sides of the rear press body 520. Each set of flattening drive assemblies 542 is used to drive the corresponding flattening assembly 543 to move, so that the flattening assembly 543 cooperates with the pressure platform 541 to flatten the welding strip.

[0083] To improve the welding efficiency of the string welding equipment, the string welding equipment can simultaneously weld at least two sets of battery strings, i.e., two or three sets of battery strings. At this time, the number of welding strips increases accordingly. In order to ensure that each welding strip can be flattened, a flattening component 543 is set for each welding strip. Each flattening component 543 is driven by an independent flattening drive component 542. By improving the layout and structure of the flattening drive component 542, the flattening drive component 542 array is arranged on both sides of the rear press body 520 to meet the layout of multiple flattening drive components 542.

[0084] It is understood that the welding strip post-pressing device 500 provided in the embodiments of the present invention arranges multiple sets of flattening drive components 542 arrayed on both sides of the post-pressing machine body 520. Each set of flattening drive components 542 is used to drive the corresponding flattening component 543 to move, so that the flattening component 543 cooperates with the pressure table 541 to flatten the welding strip. This arrangement can arrange more flattening drive components and corresponding flattening components 543, thereby meeting the requirement of processing multiple welding strips at the same time. Under the premise of reducing the size of the string welding equipment, it can play a positive role in improving the production efficiency of the string welding equipment.

[0085] Continue reading Figure 12 And see also Figure 13 and Figure 14 In some embodiments of the present invention, each flattening drive assembly 542 includes a flattening drive component 5421 and a drive block 5422.

[0086] The flattening drive component 5421 is fixed to the rear press body 520. The flattening drive component 5421 can be a linear drive component, which may include a linear module, a cylinder, etc.

[0087] The drive block 5422 is fixed to the output end of the flattening drive component 5421. The drive block 5422 has a drive surface 5422-1 and a clearance surface 5422-2 that are connected to each other. The clearance surface 5422-2 is inclined, that is, the distance between the drive surface 5422-1 and the clearance surface 5422-2 and the pressure table 541 is different. On the same horizontal plane, from the drive surface 5422-1 to the direction away from the drive surface 5422-1, the distance between the clearance surface 5422-2 and the pressure table 541 gradually increases. The driving block 5422 can perform linear reciprocating motion under the action of the flattening driving component 5421, so that the driving surface 5422-1 and the clearance surface 5422-2 alternately abut against the flattening component 543. That is, the driving surface 5422-1 abuts against the flattening component 543, or the clearance surface 5422-2 abuts against the flattening component 543, so that the driving direction of the flattening driving component 5421 is perpendicular to the movement direction of the corresponding flattening component 543. By setting it in this way, the driving direction of the flattening driving component 5421 can be changed to deploy more flattening driving components 5421, thereby satisfying the simultaneous flattening of multiple welding strips and providing a basis for improving the welding strip processing efficiency.

[0088] Essentially, by setting up a drive block 5422 and setting a drive surface 5422-1 and a clearance surface 5422-2 on the drive block 5422, the drive surface 5422-1 and the clearance surface 5422-2 can switch between contacting the flattening component 543, thereby converting the horizontal movement of the flattening drive component 5421 into the vertical reciprocating movement of the flattening component 543. This increases the number of flattening drive components 5421 that can be accommodated in the same space, increases the number of welding strips processed simultaneously, improves the welding strip processing efficiency, and makes the overall structure more compact, thus improving the space utilization of the string welding equipment.

[0089] When the driving surface 5422-1 abuts against the corresponding flattening component 543, the flattening component 543 moves toward the pressure table 541 and cooperates with the pressure table 541 to flatten the welding strip. When the clearance surface 5422-2 abuts against the corresponding flattening component 543, the flattening component 543 moves away from the pressure table 541, and a clearance gap is provided between it and the pressure table 541 for the welding strip to pass through.

[0090] Continue reading Figures 9 to 11 In some embodiments of the present invention, the flattening drive component 5421 includes a plurality of drive elements 5421-1 and at least two air supply elements 5421-2. Each air supply element 5421-2 is connected to an air source and a corresponding drive element 5421-1, respectively, for supplying air to the corresponding drive element 5421-1. Adjacent air supply elements 5421-2 are spaced apart or staggered.

[0091] Multiple drive elements 5421-1 are arranged along the length of the rear compressor body 520. The specific number and arrangement of drive elements 5421-1 can be selected according to actual needs. For example, in this embodiment, drive elements 5421-1 are arranged in groups of five on both sides of the rear compressor body 520, with the drive elements 5421-1 on both sides arranged alternately. The number of air supply elements 5421-2 is determined according to the number of drive elements 5421-1. When the number of drive elements 5421-1 increases, the number of air supply elements 5421-2 increases accordingly. For example, in this embodiment, three groups of air supply elements 5421-2 are arranged at intervals. Each group of air supply elements 5421-2 is connected to a group of drive elements 5421-1 on both sides for diverting air supply to the drive elements 5421-1 on it.

[0092] Adjacent gas supply elements 5421-2 are spaced apart or staggered, and each gas supply element 5421-2 is independently connected to a gas source. In this way, by dividing the overall gas supply device into multiple groups of gas supply elements 5421-2 and improving the layout and structure of the corresponding gas supply elements 5421-2, each gas supply element 5421-2 is independently connected to a gas source. This shortens the flow path of the supply and exhaust airflow, reduces the corresponding airflow loss, ensures the stability of the gas source of the gas supply elements 5421-2, and ensures that the gas supply elements 5421-2 move synchronously to achieve the purpose of synchronous gas supply, making the welding strip processing process smoother.

[0093] Essentially, the function of the air supply element 5421-2 is similar to that of a distributor, which ensures that the airflow entering the air intake channel 4331-1 from the air source is evenly distributed through multiple interfaces and then enters the corresponding drive element 5421-1, thereby achieving uniform and equal air supply to the corresponding drive element 5421-1, optimizing the air supply performance of the air supply element 5421-2, and enabling the drive element 5421-1 to move synchronously, achieving the purpose of synchronous air supply, and thus enabling the welding strip to be flattened synchronously.

[0094] Continue reading Figures 12 to 14 In some embodiments of the present invention, the flattening component 543 includes a transmission block 5431 and a flattening component 5432. The transmission block 5431 abuts against the driving block 5422. The transmission block 5431 may be a wedge block that adapts to the shape of the driving block 5422. That is, the transmission block 5431 is provided with an inclined surface that cooperates with the avoidance surface 5422-2, and the transmission block 5431 is provided with a driving plane that cooperates with the driving surface 5422-1.

[0095] When the clearance surface 5422-2 of the drive block 5422 abuts against the inclined surface of the transmission block 5431, the flattening component 5432 is in the clearance position, that is, there is a certain gap between the flattening component 5432 and the pressure plate 541. When the drive surface 5422-1 of the drive block 5422 abuts against the drive plane of the transmission block 5431, the flattening component 5432 is in the pressing position, that is, the flattening component 5432 applies pressure to the welding strip.

[0096] The flattening component 5432 includes a guide 5432-1, a pressure rod 5432-2, and a first elastic element 5432-3. The guide 5432-1 is located on the rear press body 520. The pressure rod 5432-2 is fixedly connected to the transmission block 5431, and the pressure rod 5432-2 is slidably engaged with the guide 5432-1. The first elastic element 5432-3 is sleeved on the outside of the pressure rod 5432-2. One end of the first elastic element 5432-3 abuts against the transmission block 5431, and the other end of the first elastic element 5432-3 abuts against the guide 5432-1. The first elastic element 5432-3 can be a spring. When the pressure rod 5432-2 moves toward the pressure platform 541, that is, when it is pressed down, the first elastic element 5432-3 undergoes elastic deformation, which has the function of elastic reset. When the pressure rod 5432-2 moves away from the pressure plate 541, the first elastic element 5432-3 rebounds and drives the pressure rod 5432-2 to reset. By setting the first elastic element 5432-3 on the pressure rod 5432-2, the pressure rod 5432-2 absorbs the impact force of the pressure rod 5432-2 during the stamping process, so as to achieve the purpose of micro-pressure and avoid the pressure rod 5432-2 from damaging the welding strip.

[0097] Specifically, the guide component 5432-1 includes a guide plate (not labeled in the figure) and a linear bearing (not labeled in the figure) disposed on the guide plate. The pressure rod 5432-2 is slidably engaged with the guide plate and the linear bearing, respectively. The lifting and lowering movement of the pressure rod 5432-2 is guided by the linear bearing and the guide plate to avoid the pressure rod 5432-2 from tilting during the movement, thereby improving the quality of the weld strip flattening.

[0098] Continue reading Figures 12 to 14 In some embodiments of the present invention, the flattening assembly 543 further includes a transmission roller 5433, which is rotatably connected to the transmission block 5431. The transmission roller 5433 rolls with the drive block 5422, which means that the sliding friction between the transmission block 5431 and the drive block 5422 is converted into rolling friction by the transmission roller 5433, so as to reduce the friction between the drive block 5422 and the transmission block 5431 and avoid the drive block 5422 from getting stuck during the movement.

[0099] Specifically, the transmission block 5431 is provided with a receiving groove, and the two opposite sides of the receiving groove are provided with mating grooves. The wheel body of the transmission roller 5433 is located in the receiving groove, and the axle of the transmission roller 5433 is located in the mating groove. The transmission roller 5433 alternately contacts the driving surface 5422-1 and the clearance surface 5422-2, so that the pressure rod 5432-2 can perform the pressing and resetting actions.

[0100] When the drive block 5422 moves forward under the action of the drive element 5421-1, the transmission roller 5433 transitions from the clearance surface 5422-2 to the drive surface 5422-1, thereby driving the pressure rod 5432-2 to move downward. When the drive block 5422 moves backward under the action of the drive element 5421-1, the transmission roller 5433 transitions from the drive surface 5422-1 to the clearance surface 5422-2, engaging in a pressing action on the pressure rod 5432-2, thereby resetting the pressure rod 5432-2.

[0101] It should be noted that a first mold 5432-4 is fixedly provided at one end of the pressure rod 5432-2 facing the pressure table 541, and a second mold 5411 that cooperates with the first mold 5432-4 is provided on the pressure table 541. The welding strip is flattened into a preset shape by the cooperation of the first mold 5432-4 and the second mold 5411. The structure and setting position of the first mold 5432-4 and the second mold 5411 can be determined according to the shape required for welding.

[0102] Continue reading Figures 12 to 14 In some embodiments of the present invention, a guide roller 523 is provided on the rear press body 520 at a position corresponding to the drive block 5422. The guide roller 523 rolls in contact with the drive block 5422, and the axis of the guide roller 523 is perpendicular to the driving direction of the flattening drive component 5421.

[0103] The rear press body 520 includes a mounting base 521 and a mounting beam 522. The mounting beam 522 is spaced above the mounting base 521 and is parallel to the mounting base 521. Two limiting plates are arranged opposite each other between the mounting beam 522 and the mounting base 521, forming a limiting space. The flattening assembly 543 performs linear reciprocating motion within this limiting space. Multiple limiting grooves 5221 are spaced apart on the side of the mounting beam 522 facing the mounting base 521, and guide rollers 523 are rotatably disposed within the corresponding limiting grooves 5221.

[0104] The guide roller 523 and the transmission roller 5433 engage in a pressing action to guide the drive block 5422, preventing the drive block 5422 from shifting position. Alternatively, a limiting groove 5221 can be provided on the mounting beam 522 at the position corresponding to the drive block 5422. The drive block 5422 can slide with the limiting groove 5221, which provides guidance. It is necessary to ensure that the precision of the limiting groove 5221 meets the corresponding requirements to prevent the drive block 5422 from getting stuck due to friction with the groove wall of the limiting groove 5221.

[0105] It should be noted that each flattening drive assembly 542 has a separate guide roller 523 for its drive block 5422. Alternatively, all the guide rollers 523 can be integrated into one unit, i.e., a roller shaft, so that each drive block 5422 makes rolling contact with the roller shaft.

[0106] Continue reading Figures 9 to 11 In some embodiments of the present invention, the rear pressure mechanism 530 includes a pressing component 531 and a rear pressure drive component 532.

[0107] The clamping assembly 531 includes a clamping plate 5311 and a plurality of rod-shaped clamping members 5312 fixedly disposed on the clamping plate 5311. The specific number of clamping members 5312 can be selected according to the number of welding strips, with each clamping member 5312 corresponding to clamp one welding strip. The rear pressure drive assembly 532 includes a rear pressure drive component 511 and a rear pressure guide component 512. Both the rear pressure drive component 511 and the rear pressure guide component 512 are fixed to the rear pressure machine body 520. The rear pressure guide component 512 is slidably engaged with the clamping plate 5311. The output end of the rear pressure drive component 511 is fixed to the clamping plate 5311 and is used to drive the clamping plate 5311 to perform linear reciprocating motion along the extension direction of the rear pressure guide component 512, thereby driving the clamping members 5312 to clamp the welding strip. Among them, the rear pressure drive component 511 is a linear drive component, and any component that can achieve linear drive is acceptable, such as a cylinder.

[0108] In some embodiments of the present invention, a second elastic element 5313 is sleeved on the outer side of the clamping member 5312. One end of the second elastic element 5313 abuts against the clamping plate 5311, and the other end of the second elastic element 5313 abuts against the end of the clamping member 5312. The second elastic element 5313 can be a spring. When the clamping member 5312 is pressed down, the second elastic element 5313 undergoes elastic deformation and has the function of elastic reset. When the clamping member 5312 rises, the second elastic element 5313 rebounds and drives the clamping member 5312 to reset. By providing the second elastic element 5313 on the clamping member 5312, the second elastic element 5313 absorbs the impact force of the clamping member 5312 during the clamping process, thereby buffering the pressure applied by the clamping member 5312 to the welding strip. The elastic force of the second elastic element 5313 flexibly clamps the welding strip, preventing the welding strip from deforming or breaking, thereby achieving the purpose of micro-pressure.

[0109] Continue reading Figure 9 and Figure 10 In some embodiments of the present invention, the rear pressing mechanism 530 further includes a pressure plate 533, which is fixed to the rear pressing body 520 and is used to cooperate with the clamping member 5312 to clamp the welding strip. When the rear pressing mechanism 530 is not provided with a pressure plate 533, the rear pressing body 520 can act as a pressure plate 533 so that the clamping member 5312 cooperates with the rear pressing body 520 to clamp the welding strip.

[0110] Multiple second limiting members 534 are provided on the pressure plate 533. The second limiting member 534 can be a columnar structure integrally formed with the pressure plate 533, or it can be a pin. A limiting groove 5221 for conveying the welding strip is formed between two adjacent second limiting members 534. The position of the limiting groove 5221 corresponds to the position of the clamping member 5312. The position of the welding strip is restricted by the limiting groove 5221 to prevent the welding strip from shifting during the conveying process, so as to affect the processing of subsequent processes.

[0111] Continue reading Figure 9 And see also Figures 15 to 17 In some embodiments of the present invention, the welding strip pressing device 500 further includes a guiding mechanism 550 for providing guidance for the welding strip.

[0112] Along the conveying direction of the welding strip, a guiding mechanism 550 is located at the rear end of the flattening mechanism 540; the guiding mechanism 550 has a guiding gap for conveying the welding strip. Essentially, components for limiting and guiding the welding strip are provided on both sides of the flattening mechanism 540, i.e., multiple second limiting members 534 are provided on the pressure plate 533 on one side of the flattening mechanism 540, and the welding strip is conveyed between two adjacent second limiting members 534. A guiding mechanism 550 is provided on the other side of the flattening mechanism 540 to constrain the conveying position of the welding strip, preventing the welding strip from tilting and affecting the flattening process and subsequent welding strip processing.

[0113] Continue reading Figures 15 to 17 The guiding mechanism 550 includes a guiding base plate 551 and a guiding cover plate 552. The guiding base plate 551 is detachably connected to the rear press body 520. A plurality of first guiding blocks 5511 are spaced apart on the guiding base plate 551, and a first guiding groove 5512 is formed between two adjacent first guiding blocks 5511.

[0114] The guide cover plate 552 is detachably connected to the guide base plate 551. Multiple second guide blocks 5521 are spaced apart on the side of the guide cover plate 552 facing the guide base plate 551. A second guide groove 5522 is formed between two adjacent second guide blocks 5521. The second guide groove 5522 merges with the first guide groove 5512 to form a guide gap. By setting this guide gap along the conveying direction of the welding strip, the welding strip can be limited and guided, preventing deviation or twisting deformation during the conveying process. This avoids the subsequent traction device being unable to effectively clamp or clamping incorrectly, providing excellent assurance for subsequent welding quality.

[0115] In addition, a buffer groove 5523 is provided on the side of the guide cover plate 552 near the flattening mechanism 540. When the guide cover plate 552 is placed on the guide substrate 551, the buffer groove 5523 can not only facilitate the entry of the welding strip into the guide gap, but also provide a certain deformation space for the welding strip during the flattening process, so as to avoid the welding strip breaking or deforming.

[0116] The guide base plate 551 has strip-shaped connecting holes along the length of the welding strip, and the guide cover plate 552 has fixing holes at the corresponding positions of the strip-shaped connecting holes. Fasteners such as hand screws and wing screws can be threaded through the fixing holes and the strip-shaped connecting holes to the rear press body 520, thus detachably connecting the guide cover plate 552 and the guide base plate 551. By adjusting the installation position of the fasteners in the strip-shaped connecting holes, the relative position between the guide base plate 551 and the guide cover plate 552 can be adjusted, thereby adjusting the offset position of the guide gap and fine-tuning the distance between the guide mechanism 550 and the welding strip shearing device 600.

[0117] Continue reading Figures 15 to 17In some embodiments of the present invention, either the guide substrate 551 or the guide cover plate 552 is provided with a limiting part 553. The limiting part 553 may be a protrusion provided on the guide substrate 551 or the guide cover plate 552, which mainly serves the purpose of positioning. The edge of the other guide substrate 551 or the guide cover plate 552 abuts against the limiting part 553, which facilitates the accurate positioning of the guide substrate 551 and the guide cover plate 552 and can improve the assembly efficiency of the guide mechanism 550.

[0118] Continue reading Figure 9 In some embodiments of the present invention, the welding strip post-pressing device 500 further includes a post-pressing translation mechanism 510, which includes a post-pressing drive component 511 and a post-pressing guide component 512. The post-pressing body 520 is guided and cooperated with the post-pressing guide component 512, and the output end of the post-pressing drive component 511 is fixedly connected to the post-pressing body 520.

[0119] Specifically, the rear pressure guide component 512 includes a linear guide rail and a slider, with the slider slidingly engaged with the linear guide rail. The rear pressure machine body 520 is fixedly connected to the slider. The rear pressure drive component 511 is a linear actuator, which can be a cylinder, linear motor, or other components. Under the action of the rear pressure drive component 511, the rear pressure machine body 520 can be driven to perform linear reciprocating motion along the linear guide rail (i.e., the conveying direction of the welding strip) to adjust the position of the welding strip rear pressure device 500.

[0120] It is understood that the welding strip pressing device 500 provided in this embodiment of the invention adjusts the position of the welding strip pressing device 500 through the pressing translation mechanism 510, that is, adjusts the distance between the welding strip pressing device 500 and the welding strip cutting device 600, thereby adjusting the cutting length of the welding strip to suit different specifications of battery cells. Furthermore, after the welding strip pressing device 500 presses the welding strip, the pressing translation mechanism 510 can drive the welding strip towards the direction of the welding strip cutting device 600, so that the end of the welding strip is exposed at the cut position of the welding strip cutting device 600, facilitating clamping by the traction device.

[0121] In addition, by adjusting the installation position of the fasteners in the strip-shaped connecting holes, the relative position between the guide plate 551 and the guide cover plate 552 is adjusted, and the distance between the guide mechanism 550 and the welding strip cutting device 600 is finely adjusted to ensure that the distance between the guide mechanism 550 and the welding strip cutting device 600 is appropriate, so as to avoid the distance between the guide mechanism 550 and the welding strip cutting device 600 being too far, which would affect the welding strip guiding effect.

[0122] See Figure 18 and Figure 19The welding strip cutting device 600 provided in this embodiment of the invention includes a first cutting mechanism 610 and a second cutting mechanism 620 arranged opposite to each other. The first cutting mechanism 610 and the second cutting mechanism 620 cooperate with each other to cut the welding strip.

[0123] The first shearing mechanism 610 includes at least one set of first shearing components 611, each set of first shearing components 611 including a first cutter 6113. That is, at least one set of first shearing components 611 is provided, and the number of first shearing components 611 can be determined based on the number of welding strips. For example, when the string welding equipment simultaneously strings three battery strings, three sets of first shearing components 611 are provided, with the three sets of first shearing components 611 arranged side-by-side at equal intervals.

[0124] The second shearing mechanism 620 includes a shearing drive component 623 and a second shearing assembly 621. The number of the second shearing assembly 621 is adapted to the number of the first shearing assembly 611. For example, when the number of the first shearing assembly 611 is set to three sets, the number of the second shearing assembly 621 is also set to three sets, and the position of the second shearing assembly 621 corresponds to the position of the first shearing assembly 611. The second shearing assembly 621 includes a second cutter 6213. A shearing drive component 623 drives the second cutter 6213 to move closer to or away from the first cutter 6113. When the shearing drive component 623 drives the second cutter 6213 to move closer to the first cutter 6113, the second cutter 6213 and the first cutter 6113 cooperate to shear the solder strip located between the two cutters. When the shearing drive component 623 drives the second cutter 6213 to move away from the first cutter 6113, there is a gap between the second cutter 6213 and the first cutter 6113 to form a cut, through which the solder strip can pass to be transferred to the next station.

[0125] The position of at least one of the first cutter 6113 and the second cutter 6213 can be adjusted so that the distance between the first cutter 6113 and the second cutter 6213, as well as the parallelism of the first cutter 6113 or the second cutter 6213, can be adaptively adjusted.

[0126] That is, the position of the first cutter 6113 can be adjusted, while the position of the second cutter 6213 remains fixed, so that the position of the first cutter 6113 matches the position of the second cutter 6213, ensuring that the positions of the first cutter 6113 and the second cutter 6213 correspond to each other, thereby ensuring that the quality of the cut solder strip is qualified. Alternatively, the position of the second cutter 6213 can be adjusted, while the position of the first cutter 6113 remains fixed, so that the position of the second cutter 6213 matches the position of the first cutter 6113, ensuring that the positions of the first cutter 6113 and the second cutter 6213 correspond to each other, thereby ensuring that the quality of the cut solder strip is qualified. Alternatively, the positions of both the first cutter 6113 and the second cutter 6213 can be adjusted, and when adjusting the position of the first cutter 6113, the position of the second cutter 6213 can remain unchanged, so that the position of the second cutter 6213 serves as the adjustment reference for the first cutter 6113. When adjusting the position of the second cutter 6213, the position of the first cutter 6113 can remain unchanged, so that the position of the first cutter 6113 can be used as the adjustment reference for the second cutter 6213. By adjusting the two cutters simultaneously, the welding strip cutting device 600 can be more easily adjusted.

[0127] It is understood that the welding strip cutting device 600 provided in this embodiment of the invention, by setting the position of at least one of the first cutter 6113 and the second cutter 6213 to be adjustable, can adjust the position of the first cutter 6113 or the second cutter 6213 in a timely manner when the relative positions of the first cutter 6113 and the second cutter 6213, which are arranged vertically opposite each other, cannot correspond during the use of the welding strip cutting device 600. This allows the spacing between the first cutter 6113 and the second cutter 6213 and the parallelism of the first cutter 6113 or the second cutter 6213 to be adjusted accordingly, ensuring neat cutting of the welding strip and improving the efficiency of welding strip processing.

[0128] Continue reading Figure 18 and Figure 19 And see also Figure 20 In some embodiments of the present invention, the first shearing assembly 611 further includes a first blade holder 6112, which means that the first shearing assembly 611 includes a first blade holder 6112 and a first cutter 6113, wherein the first blade holder 6112 serves as a mounting carrier for the first cutter 6113, and the first cutter 6113 is mounted on the first blade holder 6112.

[0129] Specifically, the first cutter 6113 is provided with a plurality of first adjustment parts 6113-1 arranged along its own length direction. The extension direction of each first adjustment part 6113-1 is consistent with the height direction of the first cutter 6113. The first cutter 6113 is mounted on the first cutter holder 6112 through the first adjustment parts 6113-1 so that the position of the first cutter 6113 along the height direction can be adjusted.

[0130] The first adjustment part 6113-1 can be a keyway, a waist-shaped hole, or multiple holes arranged in an array. When the first adjustment part 6113-1 is a keyway or a waist-shaped hole, the extension direction of the center line of the keyway or waist-shaped hole is consistent with the height direction of the first cutter 6113. The installation position of the first cutter 6113 is adjusted by the installation position of fasteners such as bolts and screws connected to the first cutter holder 6112 and the first cutter 6113 in the keyway or waist-shaped hole.

[0131] When the first adjustment part 6113-1 uses multiple holes arranged in an array, the multiple holes are arranged in an array along the height direction of the first cutter 6113. The installation position of the first cutter 6113 is adjusted by the mating position of the bolts, screws and other fasteners connected to the first cutter holder 6112 and the first cutter 6113 with the corresponding holes.

[0132] Continue reading Figures 18 to 20 In some embodiments of the present invention, the first shearing assembly 611 further includes a first mounting block 6111. That is, the first shearing assembly 611 includes a first mounting block 6111, a first blade holder 6112 and a first cutter 6113. The first blade holder 6112 serves as the mounting carrier for the first cutter 6113, and the first cutter 6113 is mounted on the first blade holder 6112. The first mounting block 6111 can be a standard block, mainly used to calibrate the mounting position of the first blade holder 6112.

[0133] Specifically, the first cutter holder 6112 is provided with a first mounting hole (not labeled in the figure) and a first adjustment hole (not labeled in the figure). The first mounting hole is threaded with a shearing fastener 6114 such as a bolt or screw, which is threaded to the first mounting block 6111. The first adjustment hole is threaded with a shearing adjustment component 6115 such as a screw or pin, the end of which abuts against the surface of the first mounting block 6111. Through the cooperation of the shearing fastener 6114 and the shearing adjustment component 6115, the position of the first cutter 6113 in the width direction can be adjusted.

[0134] Essentially, by shearing fastener 6114 to lock the first cutter holder 6112 and the first mounting block 6111, and by shearing adjustment member 6115 abutting against the surface of the first mounting block 6111 to adjust the installation gap between the first cutter holder 6112 and the first mounting block 6111, the parallelism of the first cutter holder 6112 on the first mounting block 6111 is adjusted through this installation gap, thereby indirectly adjusting the parallelism of the first cutter 6113 fixed on the first cutter holder 6112. This allows the installation position of the first cutter 6113 to be adaptively adjusted when the positions of the first cutter 6113 and the second cutter 6213 are mismatched, ensuring that the first cutter 6113 and the second cutter 6213 meet the corresponding installation requirements.

[0135] Continue reading Figures 18 to 20 In some embodiments of the present invention, the first shearing mechanism 610 further includes a first support frame 612, which means that each group of first shearing components 611 is installed through the first support frame 612, that is, the first support frame 612 serves as the mounting carrier for all the first shearing components 611.

[0136] Specifically, the first support frame 612 is provided with a plurality of second adjustment parts 6121 arranged in an array. The extension direction of each second adjustment part 6121 is consistent with the width direction of the first cutter 6113. The corresponding first mounting block 6111 is mounted on the first support frame 612 through the second adjustment part 6121, so that the position of the first cutter 6113 along the width direction can be adjusted by the first mounting block 6111.

[0137] The structure of the second adjustment part 6121 is the same as that of the first adjustment part 6113-1. The second adjustment part 6121 can also be a keyway, a waist-shaped hole, or multiple holes arranged in an array. The specific arrangement of the second adjustment part 6121 can be set with reference to the arrangement of the first adjustment part 6113-1, and will not be described in detail here.

[0138] Essentially, the first shearing assembly 611, which is composed of the first mounting block 6111, the first blade holder 6112, and the first cutter 6113, is treated as a whole. The position of the first cutter 6113 along the width direction is further adjusted by the installation position of the first shearing assembly 611 as a whole and the second adjustment part 6121 provided on the first support frame 612.

[0139] That is, the position of the first cutter 6113 along the width direction can be adjusted by two means. The first means is to roughly adjust the position of the first cutter 6113 along the width direction by adjusting the installation position of the first shearing assembly 611 as a whole and the second adjustment part 6121 set on the first support frame 612. The second means is to adjust the position of the first cutter 6113 along the width direction more finely or accurately by cooperating with the shearing fastener 6114 and the shearing adjustment part 6115.

[0140] See Figures 21 to 23 In some embodiments of the present invention, the second shearing assembly 621 further includes a second mounting block 6211 and a second blade holder 6212, which means that the second shearing assembly 621 includes a second mounting block 6211, a second blade holder 6212 and a second cutter 6213.

[0141] The second mounting block 6211 is located at the output end of the shearing drive component 623. The second blade holder 6212 is connected to the second mounting block 6211 through the first adjustment component and the second adjustment component. The second cutter 6213 is mounted on the second blade holder 6212. The position of the second cutter 6213 along the width direction can be adjusted by the first adjustment component. The position of the second cutter 6213 along the height direction can be adjusted by the second adjustment component.

[0142] Understandably, the second cutter 6213 can be adjusted in two directions: its position along the width direction can be adjusted via the first adjustment component, and its position along the height direction can be adjusted via the second adjustment component. This two-directional positional adjustment matches the position of the first cutter 6113, ensuring that the positions of the first and second cutters 6113 are mutually adaptive. When the first and second cutters 6113 interact to shear the solder strip, the sheared end face of the solder strip is smoother, resulting in better solder strip processing.

[0143] Specifically, the first adjustment assembly includes a first connecting body (not shown in the figure) and a first adjusting body (not shown in the figure). The first connecting body is threadedly connected to the second tool holder 6212 and the second mounting block 6211, respectively. The first adjusting body is threadedly connected to the second tool holder 6212, and the end of the first adjusting body abuts against the surface of the second mounting block 6211.

[0144] Essentially, the second cutter holder 6212 and the second mounting block 6211 are locked by the first connecting body, and the first adjusting body abuts against the surface of the second mounting block 6211 to adjust the installation gap between the second cutter holder 6212 and the second mounting block 6211. The parallelism of the second cutter holder 6212 on the second mounting block 6211 is adjusted by adjusting the installation gap, thereby indirectly adjusting the parallelism of the second cutter 6213 fixed on the second cutter holder 6212. This allows the installation position of the second cutter 6213 to be adaptively adjusted when the positions of the first cutter 6113 and the second cutter 6213 are mismatched, ensuring that the first cutter 6113 and the second cutter 6213 meet the corresponding installation requirements.

[0145] Specifically, the second adjustment assembly includes an adjustment plate 6216, a plurality of second connectors 6214, and a second adjustment body 6215. The adjustment plate 6216 is embedded in the second tool holder 6212 and the second mounting block 6211. Each second connector 6214 passes through the adjustment plate 6216 and is threadedly connected to the second tool holder 6212 and the second mounting block 6211, respectively. The second adjustment body 6215 passes through the adjustment plate 6216, and the end of the second adjustment body 6215 abuts against the surface of the second tool holder 6212 or the surface of the second mounting block 6211.

[0146] By embedding the adjusting plate 6216 into the second tool holder 6212 and the second mounting block 6211, that is, the surface of the adjusting plate 6216 is approximately flush with the surface of the second tool holder 6212 or the second mounting block 6211, not only can the reliability of the structural connection be improved, but it will also not interfere with the use of subsequent workstations such as the traction device.

[0147] See Figure 18 and Figure 21 In some embodiments of the present invention, the second shearing mechanism 620 further includes a second support frame 622, which means that each group of second shearing components 621 is installed through the second support frame 622, that is, the second support frame 622 serves as the mounting carrier for all second shearing components 621.

[0148] Specifically, the second support frame 622 is provided with a mounting portion 6221 adapted to the position of the shearing drive component 623, and the second support frame 622 is provided with a support portion 6222 adapted to the position of the second mounting block 6211. Two adjacent second mounting blocks 6211 are staggered on the corresponding support portions 6222. That is, according to the structure and position of the support portion 6222, the structure of each second mounting block 6211 is adaptively adjusted so that two adjacent second mounting blocks 6211 can share a support portion 6222, and each second mounting block 6211 is guided and cooperated with the corresponding support portion 6222.

[0149] By setting a support portion 6222 on the second support frame 622 that is adapted to the position of the second mounting block 6211, and by staggering two adjacent second mounting blocks 6211 on the corresponding support portion 6222, the function of the second support frame 622 can be fully utilized. Under the premise of simultaneously satisfying the shearing of multiple pieces of welding strip and improving the welding strip processing efficiency, the volume of the welding strip shearing device 600 can be minimized, so as to reduce the space occupied by the welding strip shearing device 600 in the array welding machine.

[0150] Continue reading Figure 18 and Figure 21 In some embodiments of the present invention, the second shearing mechanism 620 further includes a first limiting component 640 and a second limiting component 650. The first limiting component 640 and the second limiting component 650 are respectively located on the movement path of the corresponding second shearing assembly 621, and are used to limit the stroke of the corresponding second shearing assembly 621 to save the running time of the second cutter 6213, thereby further improving the welding strip processing efficiency. The first limiting component 640 and the second limiting component 650 mainly limit the second mounting block 6211 in the second shearing assembly 621, thereby limiting the position of the second cutter 6213 mounted on the second mounting block 6211.

[0151] Since the stroke of the shearing drive component 623 is generally greater than the effective stroke of the second shearing assembly 621, which can be understood as the shortest distance that the second cutter 6213 of the second shearing assembly 621 moves from its initial position to the target position where it contacts the first cutter 6113 to form a shearing action, and the initial position is the position where a gap is left between the second cutter 6213 and the first cutter 6113, the efficiency of the solder strip processing can be further improved by using the cooperation of the first limiting component 640 and the second limiting component 650 to limit the stroke of the second shearing assembly 621.

[0152] Specifically, both the first limiting component 640 and the second limiting component 650 include a mounting component and a second limiting component 534. The shape of the mounting component is adapted to the structure of the installation space in which it is located. The second limiting component 534 is fixedly mounted on the mounting component and is located on the moving path of the corresponding second shearing assembly 621. The second limiting component 534 may have buffering characteristics, or a buffer pad may be provided at the end of the second limiting component 534 to prevent rigid collision between the second limiting component 534 and the corresponding second mounting block 6211.

[0153] Continue reading Figure 18 In some embodiments of the present invention, both ends of the second shearing mechanism 620 can be detachably connected to the first shearing mechanism 610, or one end of the second shearing mechanism 620 can be rotatably connected to the first shearing mechanism 610, and the other end of the second shearing mechanism 620 can be detachably connected to the first shearing mechanism 610. Essentially, by disassembling the connecting component 630 between the second shearing mechanism 620 and one end of the first shearing mechanism 610, the first shearing mechanism 610 can be flipped open around the rotatable connection point with the second shearing mechanism 620. This method is similar to a guillotine cutter, facilitating the maintenance and replacement of corresponding components in the first and second shearing mechanisms 610 and 620, and also avoiding the loss of too many disassembled parts.

[0154] When both ends of the first shearing mechanism 610 are detachably connected to the second shearing mechanism 620 via the connecting component 630, that is, when the first support frame 612 and the second support frame 622 are detachably connected, the first shearing mechanism 610 can be disassembled from either end to make the disassembly space unrestricted.

[0155] Specifically, the connecting component 630 may include a second hinge shaft 631, a fixing member 632, and a positioning pin 633. The second hinge shaft 631 is used to hinge the first support frame 612 and the second support frame 622. The fixing member 632 is fixed to the first support frame 612 or the second support frame 622. The positioning pin 633 passes through the fixing member 632 and is inserted into the second hinge shaft 631 to prevent the second hinge shaft 631 from coming out of the first support frame 612 or the second support frame 622.

[0156] It should be noted that the shearing drive component 623 may include a cylinder and a guide component. The shearing guide component 660 includes a shearing guide rail 661 and a shearing slider 662. The shearing guide rail 661 is fixed to the corresponding support part, and the shearing slider 662 is slidably engaged with the shearing guide rail 661. The two ends of the second mounting block 6211 in the second shearing assembly 621 are respectively fixed on the corresponding shearing slider 662. The output end of the cylinder is fixedly connected to the second mounting block 6211. When the cylinder works, it drives the second mounting block 6211 to perform linear reciprocating motion along the shearing guide rail 661, so that the second cutter 6213 moves closer to or away from the first cutter 6113.

[0157] Since the second cutter 6213 is located below the first cutter 6113, during the shearing process, the second cutter 6213 moves upward to approach the first cutter 6113, forming a shearing action between them, thereby shearing the solder strip. Compared to the process of driving the first cutter 6113 downward to cooperate with the second cutter 6213 for shearing, the solder strip shearing device 600 provided in this embodiment of the invention, with the second cutter 6213 moving downward, can achieve a better shearing effect on the solder strip and can prevent the sheared end of the solder strip from bending downward due to its own gravity.

[0158] Of course, the shearing drive component 623 may also include other components that enable the second shearing assembly 621 to move vertically, such as any one of a linear motor, a synchronous belt linear module, and a ball screw linear module.

[0159] For example, when the shearing drive component 623 is a ball screw linear module, including a linear guide, a ball screw nut assembly, a coupling, and a servo motor, the linear guide is fixedly mounted on a corresponding support. The ball screw nut assembly includes a screw and a screw nut, which is driven by the screw and guided by the linear guide. The servo motor is connected to the screw via a coupling. The second shearing component 621 is fixed to the screw nut. When the servo motor operates to drive the screw to rotate, it drives the screw nut to reciprocate linearly along the linear guide. The second shearing component 621 drives the second cutter 6213 to reciprocate linearly, moving it closer to or away from the first cutter 6113.

[0160] See Figures 24 to 26 The traction device 800 provided in this embodiment of the invention includes a mounting mechanism 801, at least one traction mechanism 802, and a traction drive mechanism 803. The traction mechanism 802 is mounted on the mounting mechanism 801 and is used to clamp or release the welding strip. The traction drive mechanism 803 is mounted on the frame 1 and is used to drive the traction mechanism 802 to move up, down, or horizontally. The traction mechanism 802 is capable of clamping a group of parallel welding strips.

[0161] The traction mechanism 802 includes a traction clamping component, a traction clamping drive component 820, and a buffer component 830. The traction clamping component includes a first clamping assembly 811 and a second clamping assembly 812. The first clamping assembly 811 includes at least one first clamping part 81111, and the second clamping assembly 812 includes at least one second clamping part 81211. Each first clamping part 81111 and an adjacent second clamping part 81211 form a set of grippers. The traction clamping drive component 820 is connected to the first clamping assembly 811 and the second clamping assembly 812 and is used to drive the gripper set to clamp or release the welding strip. The buffer component 830 is connected to the first clamping assembly 811 and is used to buffer the clamping force of the gripper set.

[0162] By setting a traction clamping drive component 820 to drive the first clamping component 811 and the second clamping component 812, the clamping jaws can clamp or release the welding strip. By setting a buffer component 830 connected to the first clamping component 811 to buffer the clamping force of the clamping jaws, when the clamping jaws clamp the welding strip, the buffer component 830 can buffer the clamping force of the clamping jaws on the welding strip while the clamping jaws clamp the welding strip, thereby reducing the risk of the clamping jaws damaging the welding strip and solving the problem of welding strip damage in the traction mechanism of the prior art.

[0163] It should be noted that the buffer component 830 refers to a structure that can undergo elastic deformation when subjected to external force.

[0164] The gripper assembly moves closer to or further away from the solder strip in a direction perpendicular to the solder strip's transport, thereby ensuring that the solder strip is positioned between the first gripping part 81111 and the second gripping part 81211. This facilitates accurate positioning of the solder strip and improves the welding quality of the solder strip and the battery cell.

[0165] Understandably, during the clamping process of the gripper assembly, the buffer component 830 is compressed and undergoes elastic deformation, generating a deformation force to resist the first clamping part 81111. Once the gripper assembly clamps the welding strip, the buffer component 830, while ensuring that the welding strip can be clamped, reduces the clamping force of the gripper assembly on the welding strip, thereby reducing the risk of the gripper assembly damaging the welding strip and solving the problem of welding strip damage in the existing traction mechanism.

[0166] The mounting mechanism 801 includes a housing. A traction clamping drive component 820 and a portion of the traction clamping components are mounted inside the housing; a first clamping part 81111, a second clamping part 81211, and a buffer component 830 are disposed on the outside of the housing.

[0167] The first clamping assembly 811 includes at least one first gripper 8111 and a first connecting unit 8112. The first gripper 8111 has a first clamping portion 81111. The first connecting unit 8112 is connected to the traction clamping drive component 820 and the first gripper 8111, and the first connecting unit 8112 has at least one limiting groove. The first gripper 8111 is installed in the limiting groove one-to-one, and the first clamping portion 81111 extends out of the limiting groove from the opening of the limiting groove. The buffer component 830 includes an elastic component 831. The elastic component 831 is disposed in the limiting groove and connected to the first gripper 8111 and the groove wall of the limiting groove.

[0168] The traction clamping drive component 820 drives the first connecting unit 8112, which in turn drives the first gripper 8111 to move the first clamping part 81111 closer to or further away from the second clamping part 81211, thereby clamping or releasing the welding strip. Because the upper part of the first gripper 8111 is located within a limiting groove and connected to another wall of the limiting groove via an elastic component 831, when the welding strip is clamped, the elastic component 831 is compressed and undergoes elastic deformation. The deformation force of the elastic component 831 resists the first gripper 8111, thereby reducing the clamping force of the first clamping part 81111 and the second clamping part 81211 on the welding strip, preventing damage to the welding strip, and solving the problem of welding strip damage in existing traction mechanisms.

[0169] The elastic component 831 includes a spring or a rubber pad. Specifically, the first gripper 8111 abuts against one wall of the limiting groove, and the two ends of the spring are respectively connected to the first gripper 8111 and the other wall of the limiting groove.

[0170] The buffer component 830 also includes a hinge assembly 8332; the hinge assembly 8332 is disposed between the elastic component 831 and the first clamping part 81111, is fixedly connected to the side of the first connecting unit 8112 away from the mounting mechanism 801, and is hinged to the side of the first gripper 8111 away from the mounting mechanism 801. Specifically, the buffer component 830 is fixedly connected to the side of the first connecting unit 8112 away from the outer shell, and is hinged to the side of the first gripper 8111 away from the outer shell.

[0171] During the clamping of the solder ribbon, the elastic deformation of the elastic component 831 causes a certain lag as the first clamping part 81111 approaches the second clamping part 81211. This may result in the actual clamping force of the gripper assembly on the solder ribbon being greater than the required clamping force. Although the elastic deformation force of the elastic component 831 helps to offset this, it is still greater than the required clamping force, increasing the risk of damaging the solder ribbon. To solve this problem, in the specific implementation of this invention, through the elastic... A hinge assembly 8332 is provided between component 831 and the first clamping part 81111. The hinge assembly 8332 is fixedly connected to the side of the first connecting unit 8112 away from the outer shell and hinged to the side of the first gripper 8111 away from the outer shell. When the upper end of the first gripper 8111 is subjected to an external force, causing the first clamping part 81111 to move towards the second clamping part 81211, the first clamping part 81111 will rotate relative to the hinge assembly 8332 and move towards the second clamping part 81211 first, thereby achieving the clamping of the welding strip. After the gripper assembly clamps the welding strip, the first gripper 8111 stops moving, and the elastic component 831 is compressed to apply a reaction force to the first gripper 8111, reducing the force of clamping the welding strip and thus reducing the risk of damaging the welding strip.

[0172] In addition, because the first clamping part 81111 and the second clamping part 81211 have high precision requirements, errors may occur during the assembly process, causing the first clamping part 81111 and the second clamping part 81211 to shift. This shift will affect the welding precision of the solder strip and the battery cell. In a specific embodiment of the present invention, the above problem can be effectively solved by setting the hinge assembly 8332, reducing the impact of processing and assembly errors.

[0173] The hinge assembly 8332 includes a connecting block 8321 and a hinge member 8322. The connecting block 8321 is fixedly connected to the first connecting unit 8112, and the hinge member 8322 is hinged to the connecting block 8321 and the first gripper 8111. The connecting block 8321 not only enables the hinge of the first gripper 8111, but also connects the first gripper 8111 to the first connecting unit 8112, achieving synchronous movement between the first gripper 8111 and the first connecting unit 8112.

[0174] The hinge 8322 includes a protrusion and a hinge hole; one of the protrusion and the hinge hole is disposed in the connecting block 8321, and the other of the protrusion and the hinge hole is disposed in the first gripper 8111. The protrusion is rotatable within the hinge hole. Specifically, the connecting block 8321 has a protrusion formed on the side facing the first gripper 8111, and the first gripper 8111 has a hinge hole on the side facing the connecting block 8321.

[0175] A mounting groove 81112 is formed at the position opposite to the connecting block 8321 of the first gripper 8111. A first limiting part is formed at one end of the connecting block 8321, and a second limiting part is formed at the other end. The first limiting part is installed in the mounting groove 81112, and a first gap is reserved between the upper end of the first limiting part and the upper wall of the mounting groove 81112, and a second gap is reserved between the lower end of the first limiting part and the lower wall of the mounting groove 81112, in order to reserve movement space for the rotation of the first gripper 8111. The second limiting part is located in an adjacent limiting groove. The portion between the first limiting part and the second limiting part of the connecting block 8321 is connected to the common groove wall of the adjacent limiting groove by screws.

[0176] Specifically, a hinge hole is provided in the mounting groove 81112, and a protrusion is formed in the first limiting part. The mounting mechanism 801 includes a housing, and the first connecting unit 8112 includes a first connecting member 81121 and a second connecting member 81122; the first connecting member 81121 is disposed on the outside of the housing, and a limiting groove is disposed in the first connecting member 81121; the second connecting member 81122 is disposed inside the housing and connects the first connecting member 81121 and the traction clamping drive component 820. Specifically, the first connecting member 81121 and the second connecting member 81122 form an L-shaped structure of the first connecting unit 8112, and the limiting groove is vertically disposed on the outside of the housing. The second connecting member 81122 increases the transmission distance, and the traction clamping drive component 820 drives the first connecting member 81121 through the second connecting member 81122, thereby causing the first clamping part 81111 to move closer to or away from the second clamping part 81211.

[0177] The traction clamping drive component 820 is disposed inside the housing. The second connector 81122 includes a second connecting plate, which is placed horizontally. The first connector 81121 includes a first connecting plate, which is placed vertically. Limiting grooves are provided at intervals on the first connecting plate, with the openings of the limiting grooves facing downwards.

[0178] A positioning part 81123 is provided between the first connector 81121 and the second connector 81122 to facilitate installation and positioning. Specifically, the first connector 81121 has a protrusion on the side facing the second connector 81122, and the second connector 81122 has a stop on the side facing the first connector 81121. The protrusion is inserted into the stop to limit the positioning and installation of the first connector 81121 and the second connector 81122.

[0179] The second clamping assembly 812 includes at least one second gripper 8121 and a second connecting unit 8122. The second gripper 8121 has a second clamping portion 81211. The second connecting unit 8122 is connected to the end of the second gripper 8121 away from the second clamping portion 81211 and is also connected to the traction clamping drive component 820. Specifically, the second clamping portion 81211 is located below the first connecting member 81121 and is disposed opposite to the adjacent first clamping portion 81111 to form a gripper group. Multiple second grippers 8121 are connected together by the second connecting unit 8122 to achieve synchronous driving of the second grippers 8121.

[0180] The second connecting unit 8122 includes a third connecting member 81221 and a fourth connecting member 81222; the third connecting member 81221 is located outside the housing and below the first connecting member 81121; the fourth connecting member 81222 is installed inside the housing; one end of the fourth connecting member 81222 is connected to the traction clamping drive component 820, and the other end is bent downward and connected to one end of the third connecting member 81221, and the other end of the third connecting member 81221 is connected to the second gripper 8121.

[0181] The traction mechanism 802 further includes a traction guide component 840, a first sliding component 850, and a second sliding component 860. The traction guide component 840 is disposed on the housing along a direction perpendicular to the welding strip transmission direction. The first sliding component 850 is slidably engaged with the traction guide component 840 and connected to the first clamping assembly 811. The second sliding component 860 is slidably engaged with the traction guide component 840 and connected to the second clamping assembly 812. The traction guide component 840, the first sliding component 850, and the second sliding component 860 guide the first clamping assembly 811 and the second clamping assembly 812, thereby improving the clamping accuracy of the gripper assembly.

[0182] The traction guide component 840 is provided with a slide rail along its length, that is, along the direction perpendicular to the welding strip transmission; the first sliding component 850 includes a first slider; the second sliding component 860 includes a second slider; both the first slider and the second slider are slidably engaged with the slide rail.

[0183] The traction mechanism includes three traction mechanisms 802; the traction mechanisms 802 are spaced apart on the housing and can pull three sets of parallel welding strips at a time, which improves the efficiency of welding strip laying.

[0184] It is understood that the number of traction mechanisms 802 is not limited in the specific embodiments of the present invention, and can be designed according to actual needs.

[0185] The traction clamping drive component 820 includes a first traction clamping drive assembly 821 and a second traction clamping drive assembly 822. The first traction clamping drive assembly 821 is installed inside the housing and connected to the first clamping assembly 811, used to drive the first clamping part 81111 to move closer to or away from the second clamping part 81211. The second traction clamping drive assembly 822 is installed inside the housing and connected to the second clamping assembly 812, used to drive the second clamping part 81211 to move closer to or away from the first clamping part 81111. Specifically, the first traction clamping drive assembly 821 is connected to the end of the second connector 81122 away from the first connector 81121, and the second traction clamping drive assembly 822 is connected to the fourth connector 81222. The first traction clamping drive assembly 821 and the second traction clamping drive assembly 822 can drive the first connecting unit 8112 and the second connecting unit 8122 to move towards or away from each other so that the first gripper 8111 and the second gripper 8121 move closer or further away from each other, thereby achieving the clamping or loosening of the welding strip.

[0186] The first traction clamping drive assembly 821 includes a cylinder or a telescopic rod. The second traction clamping drive assembly 822 includes a cylinder or a telescopic rod.

[0187] The traction clamping drive component 820 also includes a synchronous drive component 823, which is disposed inside the housing and enables the first connecting unit 8112 and the second connecting unit 8122 to move synchronously.

[0188] The synchronous drive assembly 823 includes a synchronous drive element 8231, a synchronous drive block 8232, and two rollers 8233. The synchronous drive element 8231 is disposed inside the housing. The synchronous drive block 8232 is connected to the actuating end of the synchronous drive element 8231. The two rollers 8233 are respectively connected to the first connecting unit 8112 and the second connecting unit 8122, and the synchronous drive block 8232 is located between the two rollers 8233. Both sides of the synchronous drive block 8232 facing the rollers 8233 are set as inclined surfaces, and each inclined surface abuts against one roller 8233. When the synchronous drive element 8231 drives the synchronous drive block 8232 to move, it can drive the first connecting unit 8112 and the second connecting unit 8122 to move away from each other through the rollers 8233. In some optional embodiments, the synchronous drive element 8231 is a cylinder.

[0189] The traction clamping drive component 820 also includes a reset component 824, whose two ends are respectively connected to the first connecting unit 8112 and the second connecting unit 8122, for driving the first connecting unit 8112 and the second connecting unit 8122 to reset. The reset component 824 includes a spring.

[0190] Because the synchronous drive block 8232 has an inclined surface on one side facing the two rollers 8233, and the distance between the two inclined surfaces gradually decreases, the gripper assembly of the present invention has three states: clamping state, micro-clamping state, and loosening state. When the synchronous drive block 8232 is no longer between the two rollers 8233, the reset component resets, causing the first connecting unit 8112 and the second connecting unit 8122 to move closer together, and the gripper assembly returns to the clamping state. When the synchronous drive block 8232 enters between the two rollers 8233, the gripper assembly loosens. When the synchronous drive block 8232 moves to a certain position, it stops moving. At this time, the gripper assembly can still clamp the welding strip, which is the micro-clamping state. When the widest part of the synchronous drive block 8232 is between the two rollers 8233, the gripper assembly completely releases the welding strip.

[0191] The first clamping assembly 811 also includes a first limiting unit, which is disposed inside the housing and located on the side of the second connector 81122 away from the fourth connector 81222, and cooperates with the fourth connector 81222 to limit the first connector 8112.

[0192] The second clamping assembly 812 also includes a second limiting unit, which is disposed inside the housing and located on the side of the fourth connector 81222 away from the second connector 81122, and cooperates with the second connector 81122 to limit the second connector 8122.

[0193] By limiting the second connector 81122 and the fourth connector 81222 respectively by the first limiting unit and the second limiting unit, the clamping force of the first clamp 8111 and the second clamp 8121 can be kept within a certain range, thereby reducing the damage to the welding strip when the first clamp 8111 and the second clamp 8121 clamp the welding strip.

[0194] The traction drive mechanism 803 includes a first traction drive component 870 and a second traction drive component 880; the first traction drive component 870 is connected to the bottom of the housing of the traction mechanism and is used to drive the traction mechanism to lift and lower; the first traction drive component 870 is slidably connected to the frame, and the second traction drive component 880 is connected to the first traction drive component 870 and is used to drive the traction mechanism to slide horizontally through the first traction drive component 870.

[0195] The first traction drive component 870 is a belt transmission structure. Specifically, the first traction drive component 870 includes a first traction drive assembly and a first traction transmission assembly. One end of the first traction transmission assembly is connected to the first traction drive assembly, and the other end is connected to the housing of the traction mechanism. The first traction transmission assembly includes a driving wheel, a transmission belt, and a driven wheel. The driving wheel and the driven wheel are spaced apart along the lifting direction. The driving wheel is connected to the drive end of the first traction drive assembly, and the transmission belt is fitted over the driving wheel and the driven wheel. The housing is mounted on one side of the transmission belt. The first traction drive assembly drives the driving wheel to rotate, thereby causing the rotating belt to lift and lower the housing.

[0196] The second traction drive component 880 has a transmission structure. Its specific structure is the same as the first traction drive component 870, specifically, the driving wheel and driven wheel are spaced apart horizontally. The first traction drive component 870 and the second traction drive component 880 can also be cylinders or linear motors.

[0197] This invention also provides a method for processing solder strips based on a solder strip processing device, comprising:

[0198] First, the traction device 800 clamps the welding strip and pulls it to a first preset position. At this first preset position, the welding strip front pressing device 400 presses the welding strip tightly. The front pressing translation mechanism 410 drives the welding strip front pressing device 400 to move backward, that is, to move away from the welding strip shearing device 600, so that the welding strip undergoes plastic deformation and becomes taut. When determining whether the traction device 800 is clamping the welding strip, this can be done by visual inspection or by using appropriate sensors, such as displacement sensors or pressure sensors. The displacement of the traction device determines whether the traction device 800 is clamping the welding strip.

[0199] Next, the pressing mechanism 530 presses the welding strip, the flattening mechanism 540 flattens the welding strip, and the traction device 800 pulls the welding strip to the second preset position. At the second preset position, the welding strip cutting device 600 cuts the welding strip to complete the welding strip processing to the target length. This process can simultaneously process multiple sets of welding strips for shaping, flattening, and cutting, resulting in high processing efficiency.

[0200] Furthermore, after the control strip shearing device 600 cuts the strip, the back pressure translation mechanism 510 moves to drive the strip back pressure device 500 to move toward the strip shearing device 600, so that the strip is exposed in the cut of the strip shearing device 600, ready for the next clamping by the traction device 800.

[0201] Since the welding strip is clamped by the traction device 800 and pulled to the first preset position, the rear pressure translation mechanism 510 drives the welding strip rear pressure device 500 to move back to the initial position, so as to prepare for the next transfer of welding strip to expose the cutting position of the welding strip cutting device 600, the running time can be saved and the welding strip processing efficiency can be further improved.

[0202] See Figure 27 The present invention also provides an array welding machine, which can be understood as a string welding machine capable of simultaneously outputting at least two strings of batteries. The array welding machine includes a frame and the aforementioned welding strip processing equipment, which is located on the frame.

[0203] See Figures 27 to 36 The welding strip processing equipment also includes a welding strip feeding device 100, a welding strip pretreatment device 200, and a wire changing and connecting device 300. The welding strip feeding device 100 is used to supply welding strips to the entire welding strip processing equipment, and the welding strip pretreatment device 200 is used to dip the corresponding welding strips in flux to facilitate the connection of welding strips.

[0204] like Figure 28 As shown, the line-changing wiring device 300 includes a bracket (not shown), a welding clamp component 320, and a lower clamp component 340. The welding clamp component 320 is disposed on the bracket and is used to clamp a set of input welding strips to be welded and weld the set of input welding strips to be welded together with the output welding strips. The lower clamp component 340 is disposed on the bracket and located below the welding clamp component 320. The lower clamp component 340 is used to cut the set of input welding strips connected to the output welding strips and clamp the output welding strips.

[0205] The cable changing and wiring device 300 provided by the present invention cuts a set of input welding strips connected to the output welding strips through the lower clamping plate component 340 and clamps the output welding strips; the welding clamping plate component 320 clamps a set of input welding strips to be welded and welds the set of input welding strips to be welded together with the output welding strips; the entire cable changing and wiring process is automatically completed by the cable changing and wiring device 300 without manual operation, which improves work efficiency and reduces labor costs.

[0206] like Figures 28 to 32As shown, the welding clamp component 320 includes two welding clamp assemblies arranged symmetrically. Each welding clamp assembly includes a welding plate driving mechanism (not shown), a first clamp 322, a heating mechanism, and a first clamping mechanism 324. The first clamp 322 is vertically arranged and slides with the bracket. Specifically, each end of the first clamp 322 has a connecting plate perpendicular to it. A slider is provided on the connecting plate, and the slider slides with a first slide rail. The first slide rail is horizontally arranged and connected to the bracket. Multiple vertically extending welding strip limiting grooves 325 are provided on one side of each of the two first clamps 322. These grooves are spaced apart along the length of the first clamp 322, and a limiting ridge is formed between adjacent grooves. The welding strip limiting grooves 325 of the two first clamps 322 are staggered, so that the welding strip limiting groove 325 of one first clamp 322 corresponds one-to-one with the limiting ridge of the other first clamp 322.

[0207] The welding plate driving mechanism is connected to the bracket and the first clamping plate 322. The welding plate driving mechanism is used to drive the first clamping plate 322 closer to or further away from another first clamping plate 322. The welding plate driving mechanism is a cylinder; the cylinder body is connected to the bracket, and the cylinder piston rod is connected to the connecting plate. The cylinder is arranged along the length of the first slide rail. Of course, the specific type of welding plate driving mechanism is not limited to this; it can also be a linear push rod, a hydraulic cylinder, or other linear drive mechanism.

[0208] When the cylinder extends, it drives the first clamping plate 322 to move closer to the other first clamping plate 322, so that the limiting protrusion of the first clamping plate 322 enters the welding strip limiting groove 325 of the other first clamping plate 322, thereby clamping the output welding strip and the welding strip to be welded in the corresponding welding strip limiting groove 325.

[0209] A heating mechanism is disposed on the first clamping plate 322. The heating mechanism is used to heat the first clamping plate 322, so that the output welding strip clamped in the welding strip limiting groove 325 is thermally fused together with the welding strip clamp to be welded, thereby achieving a welding connection. A first clamping mechanism 324 is disposed on the first clamping plate 322. The first clamping mechanism 324 is used to clamp a set of input welding strips to be welded.

[0210] It should be noted that during equipment operation, there are two types of welding strip inputs. While one set of input welding strips is in use, the other set is kept as a backup. The backup set of input welding strips is called the set of input welding strips to be welded. While one set of welding strips is in use, the set of input welding strips to be welded can be pulled to the first clamping mechanism 324 in advance for clamping, in preparation for subsequent welding. Since the alternating use of the two sets of input welding strips does not affect the normal operation of the entire equipment, work efficiency is improved.

[0211] like Figure 29As shown, in this embodiment, the first clamping mechanism 324 is provided in three sets. The three sets of first clamping mechanisms 324 are arranged at intervals along the length direction of the first clamping plate 322. Of course, the number of first clamping mechanisms 324 is not limited to three sets, but can also be four sets, five sets or more, depending on the number of groups divided by the welding strip.

[0212] The first clamping plate 322 has multiple heating holes (not shown) arranged at intervals along its length. The heating mechanism includes multiple electric heating elements, which are inserted into the heating holes one by one. In this embodiment, the electric heating element is an electric heating rod. Of course, the specific type of electric heating element is not limited to this; it can also be an electric heating wire or an electric heating plate.

[0213] like Figures 29 to 31 As shown, the first clamping mechanism 324 includes a first clamping member 3241, a second clamping member 3243, a first clamping drive member 3245, and a second clamping drive member 3246. The first clamping member 3241 is slidably disposed on the upper part of the first clamping plate 322. The first clamping member 3241 is arranged along the length direction of the first clamping plate 322. The first clamping member 3241 is provided with a plurality of first clamping parts 3242, which are spaced apart along the length direction of the first clamping plate 322.

[0214] The second clamping member 3243 is slidably disposed on the upper part of the first clamping plate 322. The second clamping member 3243 is arranged along the length direction of the first clamping plate 322 and is provided with a plurality of second clamping parts 3244. The plurality of second clamping parts 3244 are spaced apart along the length direction of the first clamping plate 322, and the second clamping parts 3244 are correspondingly disposed between two adjacent first clamping parts 3242. A clamping gap is formed between the first clamping parts 3242 and the second clamping parts 3244. The clamping gap corresponds one-to-one with the welding strip limiting groove 325 of the first clamping plate 322, and the clamping gap and the corresponding welding strip limiting groove 325 are on the same vertical line.

[0215] A first clamping drive member 3245 is disposed on the first clamping plate 322 and connected to the first clamping member 3241. The first clamping drive member 3245 drives the first clamping member 3241 to move, so that the first clamping part 3242 moves closer to or further away from the second clamping part 3244. A second clamping drive member 3246 is disposed on the first clamping plate 322 and connected to the second clamping member 3243. The second clamping drive member 3246 drives the second clamping member 3243 to move, so that the second clamping part 3244 moves closer to or further away from the first clamping part 3242. In this embodiment, both the first clamping drive member 3245 and the second clamping drive member 3246 are cylinders. Of course, they can also be hydraulic cylinders, linear push rods, or other linear drive mechanisms.

[0216] When the first clamping drive 3245 drives the first clamping member 3241 to move along the length direction of the first clamping plate 322, the first clamping part 3242 moves closer to or away from the second clamping part 3244; when the second clamping drive 3246 drives the second clamping member 3243 to move along the length direction of the first clamping plate 322, the second clamping part 3244 moves closer to or away from the first clamping part 3242, thereby realizing the action of clamping and releasing the welding strip by cooperating the first clamping part 3242 and the second clamping part 3244.

[0217] It should be noted that the first clamping member 3241 and the second clamping member 3243 are disposed on the upper part of the first clamping plate 322. After the first clamping part 3242 and the second clamping part 3244 clamp a set of input welding strips to be welded, the two sets of input welding strips can overlap for a section. This overlapping section is located in the welding strip limiting groove 325, which serves as the part to be welded to the output welding strip later.

[0218] like Figure 29 As shown, the first clamping mechanism 324 also includes a first guide rail 3247, which is disposed on the first clamping plate 322. Specifically, the first guide rail 3247 is located on the side of the two first clamping plates 322 that are opposite to each other, that is, the side of the first clamping plate 322 that does not have the welding strip limiting groove 325. The first clamping member 3241 and the second clamping member 3243 are both slidably engaged with the first guide rail 3247. Specifically, the first guide rail 3247 is disposed along the length direction of the first clamping plate 322. Two first sliders 3248 are disposed on the first guide rail 3247. The first sliders 3248 are slidably engaged with the first guide rail 3247. The two first sliders 3248 are respectively connected to the two ends of the first clamping member 3241 through the first connecting block 3249. The first clamping drive member 3245 is connected to one of the first connecting blocks 3249.

[0219] Similarly, two second sliders 3250 are also provided on the first guide rail 3247. The second sliders 3250 slide in engagement with the first guide rail 3247. The two second sliders 3250 are respectively connected to the two ends of the second clamping member 3243 through the second connecting block 3251. The second clamping drive member 3246 is connected to one of the second connecting blocks 3251. By connecting the first guide rail 3247 with the first clamping member 3241 and the second clamping member 3243, the wobbling of the first clamping member 3241 and the second clamping member 3243 during movement can be avoided, thereby improving the clamping accuracy of the first clamping member 3241 and the second clamping member 3243.

[0220] like Figure 28As shown, the lower clamping plate component 340 includes two lower clamping plate assemblies arranged symmetrically. Each lower clamping plate assembly includes a clamping plate driving mechanism (not shown), a second clamping plate 342, and a second clamping mechanism 343. The second clamping plate 342 is arranged horizontally and slides with the bracket. Specifically, both ends of the second clamping plate 342 are provided with connecting plates, which are perpendicular to the second clamping plate 342. A slider is provided on the connecting plate, which slides with a second slide rail. The second slide rail is arranged horizontally and connected to the bracket.

[0221] The clamping plate drive mechanism is connected to the bracket and the second clamping plate 342. The clamping plate drive mechanism drives one second clamping plate 342 to move closer to or further away from the other second clamping plate 342. The clamping plate drive mechanism is a cylinder; the cylinder body is connected to the bracket, and the cylinder piston rod is connected to the connecting plate of the second clamping plate 342. The cylinder is positioned along the length of the second slide rail. To ensure balanced force distribution during the movement of the second clamping plate 342, two cylinders are provided, with the piston rods of the two cylinders connected one-to-one to the connecting plates at both ends of the second clamping plate 342. Of course, the specific type of clamping plate drive mechanism is not limited to this; it can also be a linear push rod, a hydraulic cylinder, or other linear drive mechanism.

[0222] The second clamping mechanism 343 is disposed on the second clamping plate 342. The second clamping mechanism 343 is used to cut a set of input solder strips connected to the output solder strip and clamp the output solder strip. Before welding the set of input solder strips to be welded together with the output solder strip, the set of input solder strips that is about to be used up needs to be cut. By cutting the set of input solder strips connected to the output solder strip through the second clamping mechanism 343 and then clamping the output solder strip through the second clamping mechanism 343, the output solder strip is kept in a taut state, providing good welding conditions for subsequent solder strips.

[0223] like Figure 32 and Figure 33 As shown, the second clamping mechanism 343 includes a third clamping member 3431, a fourth clamping member 3433, a third clamping drive member 3436, and a fourth clamping drive member 3437. The third clamping member 3431 is slidably disposed on the side of the second clamping plate 342 near the other second clamping plate 342, that is, the inner side of the second clamping plate 342. The third clamping member 3431 extends along the length direction of the second clamping plate 342. The third clamping member 3431 is provided with a plurality of third clamping parts 3432. The plurality of third clamping parts 3432 are spaced apart along the length direction of the second clamping plate 342, and the distance between two adjacent third clamping parts 3432 is equal.

[0224] A fourth clamping member 3433 is slidably disposed on the side of the second clamping plate 342 near another second clamping plate 342. The fourth clamping member 3433 extends along the length direction of the second clamping plate 342 and is provided with a plurality of fourth clamping portions 3434. The plurality of fourth clamping portions 3434 are spaced apart along the length direction of the second clamping plate 342, and the distance between two adjacent fourth clamping portions 3434 is equal. The fourth clamping portions 3434 are correspondingly disposed between two adjacent third clamping portions 3432. The side of the fourth clamping portion 3434 near the third clamping portion 3432 has a cutting surface 3435. When the fourth clamping portion 3434 and the third clamping portion 3432 approach each other, the welding strip is cut by the cutting surface 3435, and the output welding strip is clamped between the fourth clamping portion 3434 and the third clamping portion 3432.

[0225] The third clamping drive member 3436 is disposed on the second clamping plate 342 and connected to the third clamping member 3431. The third clamping drive member 3436 is used to drive the third clamping member 3431 to move, so that the third clamping part 3432 moves closer to or away from the fourth clamping part 3434. The fourth clamping drive member 3437 is disposed on the second clamping plate 342 and connected to the fourth clamping member 3433. The fourth clamping drive member 3437 is used to drive the fourth clamping member 3433 to move, so that the fourth clamping part 3434 moves closer to or away from the third clamping part 3432. In this embodiment, both the third clamping drive member 3436 and the fourth clamping drive member 3437 are cylinders. Of course, they can also be hydraulic cylinders, linear push rods, or other linear drive mechanisms.

[0226] When the third clamping drive 3436 drives the third clamping member 3431 to move along the length direction of the second clamping plate 342, the third clamping part 3432 moves closer to or away from the fourth clamping part 3434; when the fourth clamping drive 3437 drives the fourth clamping member 3433 to move along the length direction of the second clamping plate 342, the fourth clamping part 3434 moves closer to or away from the third clamping part 3432, thereby realizing the action of clamping or releasing the welding strip by the cooperation of the third clamping part 3432 and the fourth clamping part 3434.

[0227] like Figure 34As shown, the second clamping mechanism 343 further includes a second guide rail 3438, which is disposed on the second clamping plate 342. Specifically, the second guide rail 3438 is located on the upper surface of the second clamping plate 342. The third clamping member 3431 and the fourth clamping member 3433 are both slidably engaged with the second guide rail 3438. Specifically, the second guide rail 3438 is disposed along the length direction of the second clamping plate 342, and two third sliders 3439 are disposed on the second guide rail 3438. The third sliders 3439 are slidably engaged with the second guide rail 3438, and the two third sliders 3439 are respectively connected to the two ends of the third clamping member 3431 through a third connecting block 3440. The third clamping drive member 3436 is connected to a third connecting block 3440.

[0228] Similarly, the second guide rail 3438 is also provided with two fourth sliders 3441, which slide in engagement with the second guide rail 3438. The two fourth sliders 3441 are respectively connected to the two ends of the fourth clamping member 3433 through the fourth connecting block 3442. The fourth clamping drive member 3437 is connected to one of the fourth connecting blocks 3442. By connecting the second guide rail 3438 with the third clamping member 3431 and the fourth clamping member 3433, the misalignment of the third clamping member 3431 and the fourth clamping member 3433 during movement can be avoided, thereby improving the clamping accuracy of the third clamping member 3431 and the fourth clamping member 3433.

[0229] like Figure 28 , Figure 35 and Figure 36 As shown, the wire-changing and wiring device 300 also includes an upper clamping plate component 350. The upper clamping plate component 350 includes an upper clamping plate 351 and a third clamping mechanism 352. The upper clamping plate 351 is vertically mounted on the support and located above the welding clamping plate component 320. Multiple welding strip limiting grooves 325 are provided on one side of the upper clamping plate 351, extending vertically and spaced apart along the length of the upper clamping plate 351. The third clamping mechanism 352 is located at the lower part of the upper clamping plate 351 and is used to clamp the output welding strip. Before cutting the welding strip, clamping the output welding strip by the third clamping mechanism 352 can prevent the welding strip from moving, ensuring the cutting and welding accuracy of the welding strip.

[0230] like Figure 35 and Figure 36As shown, the third clamping mechanism 352 includes a fifth clamping member 3521, a sixth clamping member 3523, a fifth clamping drive member 3525, and a sixth clamping drive member 3526. The fifth clamping member 3521 is slidably disposed on the bottom of the upper clamping plate 351. The fifth clamping member 3521 is arranged along the length direction of the upper clamping plate 351. The fifth clamping member 3521 is provided with a plurality of fifth clamping parts 3522, which are spaced apart along the length direction of the upper clamping plate 351.

[0231] The sixth clamping member 3523 is slidably disposed at the bottom of the upper clamping plate 351. The sixth clamping member 3523 is arranged along the length direction of the upper clamping plate 351 and is provided with a plurality of sixth clamping parts 3524. The plurality of sixth clamping parts 3524 are spaced apart along the length direction of the upper clamping plate 351, and the sixth clamping parts 3524 are correspondingly disposed between two adjacent fifth clamping parts 3522. A clamping gap is formed between the fifth clamping parts 3522 and the sixth clamping parts 3524. The clamping gap corresponds one-to-one with the welding strip limiting groove 325 of the upper clamping plate 351, and the clamping gap and the corresponding welding strip limiting groove 325 are on the same vertical line.

[0232] The fifth clamping drive member 3525 is disposed on the upper clamping plate 351 and connected to the fifth clamping member 3521. The fifth clamping drive member 3525 drives the fifth clamping member 3521 to move, so that the fifth clamping part 3522 moves closer to or further away from the sixth clamping part 3524. The sixth clamping drive member 3526 is disposed on the upper clamping plate 351 and connected to the sixth clamping member 3523. The sixth clamping drive member 3526 drives the sixth clamping member 3523 to move, so that the sixth clamping part 3524 moves closer to or further away from the fifth clamping part 3522. In this embodiment, both the fifth clamping drive member 3525 and the sixth clamping drive member 3526 are cylinders. Of course, they can also be hydraulic cylinders, linear push rods, or other linear drive mechanisms.

[0233] When the fifth clamping drive 3525 drives the fifth clamping member 3521 to move along the length direction of the upper clamping plate 351, the fifth clamping part 3522 moves closer to or away from the sixth clamping part 3524; when the sixth clamping drive 3526 drives the sixth clamping member 3523 to move along the length direction of the upper clamping plate 351, the sixth clamping part 3524 moves closer to or away from the fifth clamping part 3522, thereby realizing the fifth clamping part 3522 and the sixth clamping part 3524 cooperating to complete the action of clamping and releasing the welding strip.

[0234] like Figure 35As shown, the third clamping mechanism 352 also includes a third guide rail, which is disposed on the upper clamping plate 351. Specifically, the third guide rail is located on the side of the upper clamping plate 351 where the welding strip limiting groove 325 is not provided. The fifth clamping member 3521 and the sixth clamping member 3523 are both slidably engaged with the third guide rail. Specifically, the third guide rail is disposed along the length direction of the upper clamping plate 351. Two fifth sliders are disposed on the third guide rail, and the fifth sliders are slidably engaged with the third guide rail. The two fifth sliders are respectively connected to the two ends of the fifth clamping member 3521 one-to-one through the fifth connecting block. The fifth clamping drive member 3525 is connected to a fifth connecting block.

[0235] Similarly, two sixth sliders are also provided on the third guide rail. The sixth sliders slide in engagement with the third guide rail, and the two sixth sliders are respectively connected to the two ends of the sixth clamping member 3523 through sixth connecting blocks. The sixth clamping drive member 3526 is connected to one of the sixth connecting blocks. By connecting the third guide rail to the fifth clamping member 3521 and the sixth clamping member 3523, the wobbling of the fifth clamping member 3521 and the sixth clamping member 3523 during movement can be avoided, thereby improving the clamping accuracy of the fifth clamping member 3521 and the sixth clamping member 3523.

[0236] Working principle of the 300 line-changing wiring device:

[0237] like Figures 28 to 36 As shown, during the line-changing operation, the fifth clamping drive 3525 drives the fifth clamping part 3522 to move closer to the sixth clamping part 3524, and the sixth clamping drive 3526 drives the sixth clamping part 3524 to move closer to the fifth clamping part 3522. The fifth clamping part 3522 and the sixth clamping part 3524 cooperate to clamp the output welding strip; the two first clamping plates 322 move to the left under the drive of the welding plate drive mechanism, and the overlapping parts of the two sets of input welding strips are attached to the welding strip limiting groove 325; the third clamping drive 3436 drives the third clamping plate to move closer to the sixth clamping part 3524. The holding part 3432 moves closer to the fourth clamping part 3434, and the fourth clamping drive 3437 drives the fourth clamping part 3434 to move closer to the third clamping part 3432. The third clamping part 3432 and the fourth clamping part 3434 cooperate to cut off a set of input welding strips connected to the output welding strips, and clamp the cut part of the output welding strips. The heating mechanism heats the first clamping plate 322 to weld the set of input welding strips to be welded together with the output welding strips. After welding, the two first clamping plates 322 move away from each other under the drive of the welding plate driving mechanism.
