Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment, specifically a cell welding device. Background Technology

[0002] A solar cell welding device is used to weld solar cells to welding strips. Currently, common solar cell welding devices include a belt conveyor, a welding strip laying mechanism, a solar cell laying mechanism, and a welding mechanism. The welding strip laying mechanism includes a feeding mechanism, a pressing mechanism, a cutting mechanism, and a traction mechanism arranged in sequence. The solar cell laying mechanism lays the solar cells onto the belt conveyor. The traction mechanism pulls the welding strip from the feeding mechanism to a certain length. The pressing mechanism presses down the welding strip. The cutting mechanism cuts the welding strip to obtain a predetermined length of welding strip. The traction mechanism then lays the predetermined length of welding strip onto the solar cells. Finally, the welding mechanism heats and welds the laid solar cells and welding strips.

[0003] In traditional solar cell welding equipment, the traction mechanism needs to wait for the welding strip to be cut before it can be laid onto the solar cell. When there are a large number of solar cells that need to be laid with welding strip, the traction mechanism has a long waiting time, which reduces the laying efficiency of solar cells and welding strip. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a battery cell welding apparatus, which adopts the following technical solution:

[0005] A battery cell welding apparatus includes a first conveying mechanism, a second conveying mechanism, a first transfer mechanism, a second transfer mechanism, a platform, a feeding mechanism, a cutting mechanism, a first handling mechanism, and a welding mechanism, wherein:

[0006] The first conveying mechanism and the second conveying mechanism are arranged side by side at intervals along the first direction, and both are used to convey the platform along the second direction, which is perpendicular to the first direction.

[0007] The platform can support at least two solar cells, which are arranged along the second direction.

[0008] The first conveying mechanism has a first loading station and a return station on its conveying path, and the second conveying mechanism has a second loading station, a cutting station, a third loading station, a welding station and an unloading station in sequence on its conveying path.

[0009] The feeding mechanism is configured to supply several metal wires extending in the second direction to the area above the second feeding station, with the free ends of the metal wires close to the cutting station.

[0010] The first transfer mechanism is configured to transfer the platform carrying the battery cells located at the first loading station to the second loading station;

[0011] The platform is configured to pick up the free end of the metal wire from the feeding mechanism. The second conveying mechanism is configured to convey the platform so that the platform passes through the cutting station, the third feeding station, the welding station and the unloading station in sequence. During the conveying process, the platform pulls the metal wire out from the feeding mechanism so that the metal wire is laid on each battery cell carried by the platform.

[0012] The first conveying mechanism is configured to place the press onto the battery cell located at the third loading station to press the wire onto the battery cell;

[0013] The welding mechanism is configured to weld metal wires located at the welding station to the battery cells;

[0018] As can be seen, by using the battery cell welding device provided in this application, the metal wire is laid and welded to the battery cell simultaneously during the traction process, thereby improving the laying and welding efficiency of the battery cell and the metal wire.

[0019] In some embodiments, the cell welding apparatus further includes a second transport mechanism and a third transport mechanism, wherein: the second transport mechanism is configured to load the cell onto a platform located at a first loading station; and the third transport mechanism is configured to remove the cell after wire welding from a platform located at an unloading station or a reflow station.

[0020] By setting up a second conveying mechanism, the automatic feeding of battery cells to be welded with metal wires is realized. By setting up a third conveying mechanism, the automatic unloading of battery cells after the metal wire welding is completed is realized, thus improving the efficiency of battery cell loading and unloading.

[0021] In some embodiments, the cutting mechanism is fixedly installed at the cutting station, or the cutting mechanism is installed at the end of the platform.

[0022] Two cutting mechanism settings are provided, both of which can cut the metal wire at the cutting station.

[0023] In some embodiments, a first clamping member is provided at a first end of the platform for clamping or releasing a metal wire, and a second clamping member is provided at a second end of the platform for clamping or releasing a metal wire; the first clamping member is configured to clamp the free end of the metal wire located on the feeding mechanism when the first end of the platform moves below the feeding mechanism; and the second clamping member is configured to clamp the metal wire when the platform completely leaves the cutting station.

[0024] By setting a first clamping element at the first end of the platform, the platform can pick up the free end of the metal wire from the feeding mechanism and pull the metal wire, so that the metal wire is laid on the platform during the pulling process. By setting a second clamping element at the second end of the platform, the platform can cooperate with the feeding mechanism to clamp the metal wire from the front and rear positions of the cutting station.

[0026] It is evident that by configuring the first conveying mechanism, it is possible to implement the bearing, positioning, and stable conveying of the platform, preventing the platform from shifting position during the conveying process.

[0027] In some embodiments, the second conveying mechanism includes a second guide rail, a second slide table, a second locking component, and a second driving unit, wherein: the second guide rail is arranged along a second direction, the second slide table is slidably connected to the second guide rail and is drively connected to the second driving unit; the second slide table is used to carry a platform, and the second driving unit is used to drive the second slide table to reciprocate along the second guide rail; the second locking component is installed on the second slide table and is used to lock or release the platform carried on the second slide table.

[0028] It is evident that by configuring the second conveying mechanism, it is possible to implement the bearing, positioning, and stable conveying of the platform, preventing the platform from shifting position during the conveying process.

[0029] In some embodiments, two platforms are provided, with one platform located on a first conveying mechanism and the other platform located on a second conveying mechanism, and the two platforms alternately carrying the battery cells.

[0030] By setting up two platforms, when the battery cell laying operation is carried out on the platform located on the first conveying mechanism, the wire laying and welding operation can be carried out simultaneously on the battery cells located on the platform located on the second conveying mechanism, thereby further improving production efficiency.

[0031] In some embodiments, the first transfer mechanism includes a first turning conveyor, a first transition conveyor, and a second turning conveyor, wherein: the first turning conveyor is disposed at a first loading station, the second turning conveyor is disposed at a second loading station, and the first transition conveyor is disposed between the first turning conveyor and the second turning conveyor; the first turning conveyor is configured to lift the platform located at the first loading station upward and convey the platform along a first direction to the first transition conveyor; the first transition conveyor is configured to convey the platform along the first direction to the second turning conveyor, and the second turning conveyor is configured to convey the platform along the first direction to above the second loading station and then lower the platform to the second loading station.

[0032] Through the coordination of the first steering conveyor, the first transition conveyor, and the second steering conveyor, the first transfer mechanism automatically lifts and transports the platform located at the first loading station of the first conveyor mechanism to the second loading station of the second conveyor mechanism. This lifting and conveying transfer method avoids contact and interference between the first transfer mechanism and other mechanisms such as the feeding mechanism.

[0033] In some embodiments, the second transfer mechanism includes a third turning conveyor, a second transition conveyor, and a fourth turning conveyor, wherein: the third turning conveyor is disposed at the unloading station, the fourth turning conveyor is disposed at the return station, and the second transition conveyor is disposed between the third turning conveyor and the fourth turning conveyor; the third turning conveyor is configured to lift the platform located at the unloading station upward and convey the platform along a first direction to the second transition conveyor; the second transition conveyor is configured to convey the platform along the first direction to the fourth turning conveyor, and the fourth turning conveyor is configured to convey the platform along the first direction to above the return station and then lower the platform to the return station.

[0034] Through the coordination of the third steering conveyor, the second transition conveyor, and the fourth steering conveyor, the second transfer mechanism automatically lifts and transports the platform located at the unloading station of the second conveyor to the return station of the first conveyor. This lifting and conveying method avoids contact and interference between the second transfer mechanism and other mechanisms such as the first handling mechanism and the welding mechanism.

[0035] In some embodiments, the stage includes at least two support blocks arranged side by side along a second direction, each support block being used to support and adsorb a battery cell; guide combs are provided between adjacent two support blocks and on the outer sides of the support blocks at both ends, the guide combs having a plurality of guide grooves spaced apart along a first direction, each guide groove being used to guide a metal wire.

[0036] By setting the platform to consist of at least two bearing blocks arranged side by side along the second direction, and by setting guide combs on the outside of the bearing blocks at both ends, the metal wire is guided, preventing the metal wire from shifting position during traction.

[0037] In some embodiments, the platform further includes a lifting drive unit that corresponds to each guide comb. The lifting drive unit is used to drive the corresponding guide comb to switch between a high guiding position and a low avoidance position. When the guide comb is in the high guiding position, the upper end of the guide groove is higher than the bearing surface of the platform, and the metal wire can be laid on the battery cell below after entering the guide groove. When the guide comb is in the low avoidance position, the upper end of the guide groove is lower than the feeding mechanism.

[0038] By setting the guide comb to be able to move up and down between a low avoidance position and a high guide position, the guide comb can pull the metal wire and avoid the feeding mechanism, ensuring that the platform can pick up the free end of the metal wire from the feeding mechanism.

[0039] In some embodiments, the feeding mechanism includes a feeding roller group, a guide roller group, and a pressure head, wherein: the feeding roller group is disposed in front of the second conveying mechanism, the guide roller group is disposed between the feeding roller group and the second conveying mechanism, and the pressure head is disposed near the cutting station; the feeding roller group is used to feed out a plurality of metal wires; the guide roller group is used to guide the metal wires to the pressure head, the pressure head is used to press or release the metal wires, and the free end of the metal wires extends out of the pressure head.

[0040] The feeding mechanism is able to automatically feed the metal wire through the cooperation of the feeding roller group, the guide roller group and the pressure head, and position the free end of the metal wire at the cutting station, so that the platform can pick up the free end of the metal wire from the cutting station each time.

[0041] In some embodiments, the feeding mechanism further includes a guide wheel disposed near the pressure head, the guide wheel being configured to cooperate with the guide roller assembly to guide the metal wire to the pressure head and to horizontally support the metal wire above the second feeding station.

[0042] By setting guide wheels, the metal wire is ensured to be supported horizontally above the second loading station, preventing the metal wire from sagging and obstructing the transfer and conveying of the platform.

[0043] In some embodiments, the feeding mechanism further includes a flux coating member disposed between the feeding roller group and the second conveying mechanism, the flux coating member being used to coat flux onto each metal wire.

[0044] By incorporating a flux coating component, flux is automatically applied to the metal wires before they are laid on the platform, thereby enhancing the welding strength between the metal wires and the battery cells. Attached Figure Description

[0066] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0067] The metal wire mentioned in this application has solder on its surface. When the metal wire is heated, the solder on its surface melts, thereby creating a conductive connection between the metal wire and the battery cell. The cross-section of the metal wire can be circular, triangular, rectangular, etc.

[0068] As described in the background section, in traditional solar cell welding devices, the traction mechanism needs to wait for the welding strip to be cut before it can lay the welding strip. When the welding strip to be laid is long, the traction mechanism has to wait a long time, which will reduce the laying efficiency of solar cells and welding strip.

[0069] To address this problem, this application provides a battery cell welding apparatus for laying and welding metal wires onto battery cells.

[0070] like Figures 1 to 6 As shown, the battery cell welding apparatus in this embodiment includes a first conveying mechanism 1, a second conveying mechanism 2, a first transfer mechanism 3, a second transfer mechanism 4, a platform 5, a feeding mechanism 6, a cutting mechanism (not shown in the figure), a first handling mechanism 7, and a welding mechanism 8, wherein:

[0071] The first conveying mechanism 1 and the second conveying mechanism 2 are arranged side by side at intervals along a first direction (e.g., the X direction), and both are used to convey the platform 5 along a second direction (e.g., the Y direction), which is perpendicular to the first direction.

[0072] The platform 5 can support at least two solar cells, which are arranged along the second direction.

[0073] The first conveying mechanism 1 has a first loading station A and a return station G on its conveying path, and the second conveying mechanism 2 has a second loading station B, a cutting station C, a third loading station D, a welding station E and a unloading station F on its conveying path in sequence.

[0074] The feeding mechanism 6 is configured to supply a plurality of metal wires 100 extending in the second direction to the top of the second feeding station B, such that the free ends of the metal wires are close to the cutting station C.

[0075] The first transfer mechanism 3 is configured to transfer the platform 5 carrying the battery cells 200 located at the first loading station A to the second loading station B.

[0076] The platform 5 is configured to pick up the free end of the metal wire 100 from the feeding mechanism 1. The second conveying mechanism 2 is configured to convey the platform 5, so that the platform 5 passes through the cutting station C, the third loading station D, the welding station E and the unloading station F in sequence. During the conveying process, the platform 5 pulls the metal wire 100 out from the feeding mechanism 6, so that the metal wire 100 is laid on each battery cell 200 carried by the platform 5.

[0077] The first conveying mechanism 7 is configured to place the press on the battery cell 200 located at the third loading station D to press the wire 100 onto the battery cell 200.

[0078] The welding mechanism 8 is configured to weld the metal wire located at the welding station E to the battery cell 200.

[0079] The platform 5 and the feeding mechanism 6 are also configured to press the metal wire 100 from the front and rear positions of the cutting station C when the platform 5 is completely away from the cutting station C, and the cutting mechanism is configured to cut the metal wire 100 at the cutting station C.

[0080] The second transfer mechanism 4 is configured to transfer the platform 5 located at the unloading station F to the return station G.

[0081] The first conveying mechanism 1 is also configured to transport the platform 5 back to the first loading station A after the battery cell 200, which has completed wire welding, has been removed.

[0082] The optional operating process of the battery cell welding apparatus in this embodiment is as follows:

[0083] The feeding mechanism 6 supplies several (generally 10 to 200) metal wires 100 extending in the second direction to the area above the second loading station B, and limits the free ends of the metal wires to a position close to the cutting station C. In other words, the metal wires 100 supplied by the feeding mechanism 6 are suspended above the second loading station B, and a space is formed between the metal wires 100 and the second loading station B to avoid the platform 5.

[0084] Next, the first transfer mechanism 3 transfers the platform 5 carrying the battery cells 200 located at the first loading station A to the second loading station B.

[0085] Next, the platform 5 picks up the free end of the metal wire 100. Subsequently, the second conveying mechanism 2 transports the platform 5, causing it to pass sequentially through the cutting station C, the third loading station D, the welding station E, and the unloading station F. During this process, the platform 5 pulls the metal wire 100 out from the feeding mechanism 6, and causes the metal wire 100 to be cut into sections and placed onto each of the battery cells 200 carried by the platform 5. At the same time, the first transport mechanism 7 places the clamps one by one onto the battery cells 200 that have passed through the third loading station D, thereby pressing the metal wire 100 onto the corresponding battery cell 200, and the welding mechanism 8 welds the metal wire 100 that has passed through the welding station E onto the corresponding battery cell 200.

[0086] When the carrier 5 completely leaves the cutting station C, the carrier 5 and the feeding mechanism 6 work together to press the metal wire 100 from the front and rear positions of the cutting station C. The cutting mechanism then cuts the metal wire 100 at the cutting station C. As all the battery cells on the carrier 5 are welded by the welding mechanism 8, at least two battery cells 200 with completed metal wire welding are obtained.

[0087] Subsequently, the second transfer mechanism 4 transfers the platform 5 located at the unloading station F to the reflow station G. The completed wire-welded battery cells 200 on the platform 5 are removed at the unloading station F or the reflow station G.

[0088] Finally, the first conveying mechanism 1 transports the vacated platform 5 back to the first loading station A.

[0089] Repeat the above process to perform wire welding on the next batch of battery cells.

[0090] The battery cell welding apparatus provided in this application embodiment can simultaneously place at least two battery cells 200 on a platform 5. During the movement of the platform 5, metal wires 100 can be pulled out from the feeding mechanism 6 and laid onto each battery cell 200. Subsequently, the welding mechanism sequentially welds the metal wires 100 onto each battery cell 100. After the metal wires 100 are laid, the cutting mechanism cuts the metal wires 100, thereby obtaining at least two battery cells 200 with completed metal wire welding.

[0091] As can be seen, by using the battery cell welding device provided in this application, the metal wire is laid and welded to the battery cell simultaneously during the traction process, thereby improving the laying and welding efficiency of the battery cell and the metal wire.

[0092] After removing at least two wire-welded solar cells from the platform, the wires between two adjacent solar cells can be cut as needed to obtain a solar cell wire unit, which prepares for subsequent series connection between solar cells.

[0093] The first conveying mechanism 7 can adopt any existing mechanism capable of conveying the press. For example, the first conveying mechanism 7 includes a moving part and a suction cup or magnetic suction device connected to the drive end of the moving part. The moving part drives the suction cup or magnetic suction device to translate and lift, thereby driving the suction cup or magnetic suction device to pick up the press and place the press onto the battery cell 200 located at the third loading station D. The press can adopt any existing press structure capable of simultaneously pressing all the metal wires onto the battery cell. For example, the press includes a frame and several rows of pressure pins mounted on the frame, with each row of pressure pins used to elastically press one metal wire; or, the press includes a frame and a pressure mesh mounted on the frame, with the pressure mesh pressing all the metal wires simultaneously.

[0094] The welding mechanism 8 can be a heating component that can heat the metal wire, such as an infrared lamp box, a hot air assembly, an electromagnetic heating assembly, or a laser heating assembly, so that the solder on the surface of the metal wire melts.

[0095] Optionally, the battery cell welding apparatus in this embodiment further includes a second transport mechanism and a third transport mechanism (not shown in the figure), wherein: the second transport mechanism is configured to load the battery cell 200 onto the platform 5 located at the first loading station A, thereby realizing automatic loading of the battery cell to be welded with metal wires. The third transport mechanism is configured to remove the battery cell 200 after metal wire welding from the platform 5 located at the unloading station F or the reflow station G, thereby realizing automatic unloading of the battery cell 200 after metal wire welding.

[0096] Optionally, the second conveying mechanism is provided with at least one set of first suction cups, each set of first suction cups being used to adsorb one battery cell. When the second conveying mechanism is provided with multiple sets of first suction cups, the multiple sets of first suction cups are arranged side by side to simultaneously adsorb multiple battery cells and release multiple battery cells onto the platform 5 at the same time.

[0097] Optionally, the third conveying mechanism is equipped with multiple sets of second suction cups, each set of second suction cups corresponding one-to-one with the battery cells carried on the platform 5, used to adsorb the battery cells welded on the platform one-to-one so as to remove the battery cells.

[0098] Optionally, the cell welding device also includes a fourth transport mechanism. The structure of the fourth transport mechanism is the same as that of the first transport mechanism 7. It is used to remove the clamps on the cells after welding by the welding mechanism 8 so that the third transport mechanism can pick up the welded cells.

[0099] Optionally, the cutting mechanism is fixedly installed at the cutting station C. When the platform 5 completely leaves the cutting station C, the cutting mechanism can cut the metal wire 100.

[0100] The cutting mechanism can be any existing cutting mechanism capable of cutting multiple metal wires 100. For example, the cutting mechanism includes a liftable mounting base and several cutting shears arranged side by side on the mounting base along a first direction. During the traction and laying of the metal wires 100, the mounting base is in a low clearance position, and the cutting shears are all in an open state, so that the mounting base can pass smoothly over the cutting shears. When the mounting base is completely away from the cutting station C, the mounting base rises to the high cutting position, so that each metal wire 100 falls into a corresponding cutting shear, and the cutting shears then cut the metal wires 100 simultaneously.

[0101] Alternatively, the cutting mechanism can be positioned at the end of the platform 5, so that the cutting mechanism reaches the cutting station C when the platform 5 has completely left the cutting station C. In this way, the cutting mechanism can immediately cut the metal wire 100. Optionally, the cutting mechanism includes several cutting shears arranged side-by-side along the end of the platform 5 in a first direction. During the process of the platform 5 pulling and laying the metal wire 100, each metal wire 100 falls into one of the cutting shears in an open state. When the platform 5 has completely left the cutting station C, the several cutting shears simultaneously cut the metal wire 100.

[0102] like Figure 2 As shown, optionally, the first end of the platform 5 is provided with a first clamping member 9 for clamping or releasing the metal wire, and the second end of the platform 5 is provided with a second clamping member 10 for clamping or releasing the metal wire. The first clamping member 9 is configured to clamp the free end of the metal wire 100 located on the feeding mechanism 6 when the first end of the platform 5 moves below the feeding mechanism 6. When the platform 5 completely leaves the cutting station C, the second clamping member 10 is configured to clamp the metal wire 100.

[0103] By setting a first clamping member 9 at the first end of the platform 5, the platform 5 can pick up the free end of the wire 100 from the feeding mechanism 6 and pull the wire 100.

[0104] By setting a second clamping member 10 at the second end of the platform 5, the second end of the platform 5 can cooperate with the feeding mechanism 6 to clamp the metal wire 100 from the front and rear positions of the cutting station C, thereby facilitating the cutting mechanism to cut the metal wire 100.

[0105] Optionally, the first clamping member 9 and the second clamping member 10 have the same structure. Taking the first clamping member 9 as an example, as follows... Figure 6 As shown, it includes a support plate 91 and a pressure plate 92 disposed above the support plate 91. The support plate 91 is fixedly installed at the end of the platform 5. The bearing surface of the support plate 91 is not higher than the bearing surface of the platform 5. The pressure plate 92 can be raised and lowered relative to the support plate 91 to press the metal wire 100 onto the bearing surface of the support plate 91 or to release the metal wire 100.

[0106] like Figure 1 As shown, optionally, the first conveying mechanism 1 includes a first guide rail 11, a first slide 12, a first locking assembly, and a first driving unit, wherein: the first guide rail 11 is arranged along a second direction, and the first slide 12 is slidably connected to the first guide rail 11 and is drively connected to the first driving unit. The first slide 12 is used to support the platform 5, and the first driving unit is used to drive the first slide 12 to reciprocate along the first guide rail 11. The first locking assembly is installed on the first slide 12 and is used to lock or release the platform 5 supported on the first slide 12.

[0107] The optional working process of the first conveying mechanism 1 is as follows:

[0108] When the second transfer mechanism 4 transfers the platform 5 located at the unloading station F to the first slide 12 located at the return station G, the first locking component locks the platform 5 onto the first slide 12.

[0109] Subsequently, the first slide table 12 slides to the first loading station A under the drive of the first drive unit.

[0110] After the battery cells are loaded onto the platform 5, the first locking component releases the locking of the platform 5, allowing the platform 5 carrying the battery cells to be transferred by the first transfer mechanism 3 to the second loading station B.

[0111] Subsequently, the first slide table 12, driven by the first drive unit, slides again to the return station G.

[0112] It can be seen that by setting the first conveying mechanism 1, the first conveying mechanism 1 can stably support and automatically convey the platform 5, preventing the platform 5 from shifting position during the conveying process.

[0113] The first locking component in this embodiment can be any existing locking mechanism capable of locking the platform 5 to the first slide 12. For example, the first slide 12 is provided with a locking hole, and the first locking component includes a locking pin that matches the locking hole. When the locking pin is inserted into the locking hole, the platform 5 can be locked to the first slide 12. The first driving unit can be any existing linear drive module capable of driving the first slide 12 to slide along the first guide rail 11, such as a lead screw drive module, a synchronous belt drive module, etc.

[0114] Similarly, such as Figure 1As shown, optionally, the second conveying mechanism 2 includes a second guide rail 21, a second slide 22, a second locking assembly, and a second drive unit, wherein: the second guide rail 21 is arranged along a second direction, and the second slide 22 is slidably connected to the second guide rail 21 and is drively connected to the second drive unit. The second slide 22 is used to support the platform 5, and the second drive unit is used to drive the second slide 5 to reciprocate along the second guide rail 21. The second locking assembly is installed on the second slide 22 and is used to lock or release the platform 5 supported on the second slide 22.

[0115] The optional working process of the second conveying mechanism 1 is as follows:

[0116] The second slide table 22 slides to the second loading station B under the drive of the second drive unit. After the carrier 5 carrying the battery cells is transferred to the second slide table 22 by the first transfer mechanism 3, the second locking component locks the carrier 5 onto the second slide table 22.

[0117] Subsequently, the second slide 22 carrying the carrier 5 passes sequentially through the cutting station C, the third loading station D, the welding station E, and the unloading station F under the drive of the second drive unit.

[0118] After the platform 5 slides to the unloading station F, the second locking component releases the platform 5, allowing the second transfer mechanism 4 to transfer the platform 5 to the return station G.

[0119] Subsequently, the second slide table 22 slides back to the second loading station B under the drive of the second drive unit.

[0120] It can be seen that by setting the second conveying mechanism 2, the second conveying mechanism 2 can stably support and automatically convey the platform 5, preventing the platform 5 from shifting position during the conveying process.

[0121] Similarly, in the embodiments of this application, the second locking component can be any existing locking mechanism capable of locking the platform 5 to the second slide 22, and the second driving unit can be any existing linear drive module capable of driving the second slide 22 to slide along the second guide rail 21.

[0122] like Figure 1 As shown, optionally, there are two platforms 5. When one platform 5 is located on the first conveying mechanism 1, the other platform 5 is located on the second conveying mechanism 2, and the two platforms alternately carry the battery cells.

[0123] By setting up two platforms 5, when the battery cell laying operation is carried out on the platform 5 located on the first conveying mechanism 1, the wire laying and welding operation can be carried out on the battery cells on the platform 5 located on the second conveying mechanism 2 at the same time, thereby further improving production efficiency.

[0124] like Figures 1 to 3As shown, optionally, the first transfer mechanism 3 includes a first turning conveyor 31, a first transition conveyor 32 and a second turning conveyor 33, wherein: the first turning conveyor 31 is disposed at the first loading station A, the second turning conveyor 33 is disposed at the second loading station B, and the first transition conveyor 32 is disposed between the first turning conveyor 31 and the second turning conveyor 33.

[0125] The first turning conveyor 31 is configured to lift the platform 5 located at the first loading station A upwards and convey the platform 5 along the first direction to the first transition conveyor 32. The first transition conveyor 32 is configured to convey the platform 5 along the first direction to the second turning conveyor 33. The second turning conveyor 33 is configured to convey the platform 5 along the first direction to above the second loading station B and then lower the platform 5 to the second loading station B.

[0126] Through the cooperation of the first turning conveyor 31, the first transition conveyor 32, and the second turning conveyor 33, the first transfer mechanism 3 automatically lifts and transports the platform 5 located at the first loading station A of the first conveyor mechanism 1 to the second loading station B of the second conveyor mechanism 2. This lifting and conveying transfer method avoids contact and interference between the first transfer mechanism 3 and other mechanisms such as the feeding mechanism 6.

[0127] Optionally, the first steering conveyor section 31 and the second steering conveyor section 33 adopt the same structure. Taking the first steering conveyor section 31 as an example, it includes a lifting section and a steering conveyor belt disposed on the top of the lifting section and conveying along the first direction. Correspondingly, the first slide table 12 and the second slide table 22 have the same structure, such as... Figure 3 As shown, taking the first slide table 12 as an example, it is provided with a clearance hole 121 for avoiding the first steering conveyor section 31.

[0128] When the first slide table 12, carrying the platform 5, slides to the first loading station A and the battery cells are loaded onto the platform 5, the lifting part of the first steering conveyor 31 drives the corresponding steering conveyor belt to rise to a high position through the clearance hole 121 on the first slide table 12, thereby lifting the platform 5 upwards out of the first slide table 12 and causing the steering conveyor belt of the first steering conveyor 31 to connect with one end of the first transition conveyor 32. Furthermore, when the second slide table 22 slides to the second loading station B, the lifting part of the second steering conveyor 33 drives the corresponding steering conveyor belt to rise to a high position through the clearance hole on the second slide table 22, causing the steering conveyor belt of the second steering conveyor 33 to connect with the other end of the first transition conveyor 32.

[0129] Subsequently, the steering conveyor belt of the first steering conveyor unit 31 transports the platform 5 along the first direction to the first transition conveyor unit 32, which then transports the platform 5 to the steering conveyor belt of the second steering conveyor unit 33. After the steering conveyor belt of the second steering conveyor unit 33 transports the platform 5 above the second loading station B, the lifting unit of the second steering conveyor unit 33 drives the corresponding steering conveyor belt to descend and return to its original position, thereby causing the platform 5 to fall onto the second slide table 22.

[0130] Because the platform 5 is relatively long along the second direction, in order to improve the stability of the platform 5 when it is lifted, such as Figure 3 As shown, optionally, the first steering conveyor units 31 are arranged in two parallel groups along the second direction, and the two groups of first steering conveyor units 31 cooperate to lift and convey the platform 5. Similarly, in order to improve the stability of the platform 5 when it is lowered, the second steering conveyor units 33 are arranged in two parallel groups along the second direction, and the two groups of second steering conveyor units 33 cooperate to convey and lower the platform 5.

[0131] Correspondingly, the first slide 12 and the second slide 22 are provided with two clearance holes 121 along the second direction.

[0132] like Figures 1 to 3 As shown, optionally, the second transfer mechanism 4 includes a third turning conveyor 41, a second transition conveyor 42 and a fourth turning conveyor 43, wherein: the third turning conveyor 41 is located at the unloading station F, the fourth turning conveyor 43 is located at the return station G, and the second transition conveyor 42 is located between the third turning conveyor 41 and the fourth turning conveyor 43.

[0133] The third turning conveyor 41 is configured to lift the platform 5 located at the unloading station F upwards and convey the platform 5 along the first direction to the second transition conveyor 42. The second transition conveyor 42 is configured to convey the platform 5 along the first direction to the fourth turning conveyor 43. The fourth turning conveyor 43 is configured to convey the platform 5 along the first direction to above the return station G and then lower the platform 5 to the return station G.

[0134] As can be seen, through the cooperation of the third turning conveyor 41, the second transition conveyor 42, and the fourth turning conveyor 43, the second transfer mechanism 4 automatically lifts and transports the platform 5 located at the unloading station F of the second conveyor mechanism 2 to the return station G of the first conveyor mechanism 1. The lifting and conveying transfer method avoids contact and interference between the second transfer mechanism 4 and other mechanisms such as the first handling mechanism 7 and the welding mechanism 8.

[0135] Similarly, optionally, the third steering conveyor 41 and the fourth steering conveyor 43 both include a lifting section and a steering conveyor belt disposed on the top of the lifting section and conveyed in the first direction.

[0136] When the second slide 22, carrying the platform 5, slides to the unloading station F, the lifting part of the third steering conveyor 41 drives the corresponding steering conveyor belt to rise to a high position through the clearance hole on the second slide 22, thereby lifting the platform 5 upward out of the second slide 22 and causing the steering conveyor belt of the third steering conveyor 41 to connect with one end of the second transition conveyor 42. Furthermore, when the first slide 12 slides to the return station G, the lifting part of the fourth steering conveyor 43 drives the corresponding steering conveyor belt to rise to a high position through the clearance hole on the first slide 12, causing the steering conveyor belt of the fourth steering conveyor 43 to connect with the other end of the second transition conveyor 42.

[0137] Subsequently, the steering conveyor belt of the third steering conveyor unit 41 transports the platform 5 along the first direction to the second transition conveyor unit 42, which then transports the platform 5 to the steering conveyor belt of the fourth steering conveyor unit 43. After the steering conveyor belt of the fourth steering conveyor unit 43 transports the platform 5 above the return station G, the lifting unit of the fourth steering conveyor unit 43 drives the corresponding steering conveyor belt to descend and return to its original position, thereby causing the platform 5 to fall onto the first slide table 12.

[0138] Similarly, to improve the stability of the platform 5 when it is lifted, optionally, the third steering conveyor 41 is arranged in two parallel sets along the second direction, and the two sets of third steering conveyor 41 cooperate to lift and convey the platform 5. Likewise, to improve the stability of the platform 5 when it is lowered, the fourth steering conveyor 43 is arranged in two parallel sets along the second direction, and the two sets of fourth steering conveyor 43 cooperate to convey and lower the platform 5.

[0139] like Figure 1 and Figures 4 to 6 As shown, optionally, the platform 5 includes at least two (11 in the figure) support blocks 51 arranged side by side along the second direction, each support block 51 being used to support and adsorb one battery cell 200. Guide combs 110 are provided between adjacent support blocks 51 and on the outer sides of the support blocks 51 at both ends. Each guide comb 110 has several guide grooves 111 spaced apart along the first direction, each guide groove 111 being used to guide a metal wire 100.

[0140] By setting the platform 5 to consist of at least two support blocks 51 arranged side by side along the second direction, and by providing guide combs 110 on the outer sides of the support blocks 51 at both ends and between adjacent support blocks 51, the metal wire 100 is guided, preventing the metal wire 100 from shifting position during traction.

[0141] Optionally, the platform 5 also includes a lifting drive unit corresponding to each guide comb 110. The lifting drive unit is used to drive the corresponding guide comb 110 to switch between a high guiding position and a low avoidance position. When the guide comb 110 is in the high guiding position, the upper end of the guide groove 111 is higher than the bearing surface of the platform 5, and the metal wire 100 can be laid on the battery cell 200 below after entering the guide groove 111. When the guide comb 110 is in the low avoidance position, the upper end of the guide groove 111 is lower than the feeding mechanism 6.

[0142] By setting the guide comb 110 to be able to switch between a low avoidance position and a high guidance position, the guide comb 110 can guide the metal wire 100 and avoid the feeding mechanism 6, ensuring that the platform 5 can smoothly pick up the free end of the metal wire 100 from the feeding mechanism 6.

[0143] Optional, such as Figure 6 As shown, the first clamping member 9, located at the first end of the platform 5, is outside the guide comb 110 at the first end. After the first clamping member 9 clamps the free end of the metal wire 100 on the feeding mechanism 6, the metal wire then enters the guide comb 110 for guidance and positioning. Similarly, the second clamping member 10, located at the second end of the platform 5, is outside the guide comb 110 at the second end to guide and clamp the tail end of the metal wire on the platform 5.

[0144] like Figure 1 and Figure 2 As shown, optionally, the feeding mechanism 6 includes a feeding roller group 61, a guide roller group 62, and a pressure head 63, wherein: the feeding roller group 61 is located in front of the second conveying mechanism 2, the guide roller group 62 is located between the feeding roller group 61 and the second conveying mechanism 2, and the pressure head 63 is located near the cutting station C. The feeding roller group 62 is used to feed out several metal wires 100. The guide roller group 62 is used to guide the metal wires 100 to the pressure head 63, and the pressure head 63 is used to press or release the metal wires 100, with the free end of the metal wires 100 extending out of the pressure head.

[0145] It can be seen that through the cooperation of the feeding roller group 61, the guide roller group 62 and the pressure head 63, the feeding mechanism 6 can automatically feed the metal wire 100 and position the free end of the metal wire 100 at the cutting station C, so that the platform 5 can pick up the free end of the metal wire 100 from the cutting station C each time.

[0146] like Figure 2 As shown, optionally, the feeding mechanism 6 also includes a guide wheel 64 located near the pressure head 63. The guide wheel 64 cooperates with the guide roller group 62 to guide the metal wire 100 to the pressure head 63 and to horizontally support the metal wire 100 above the second feeding station B.

[0147] By setting guide wheels 64, the metal wire 100 is ensured to be supported horizontally above the second loading station B, preventing the metal wire 100 from sagging and obstructing the transfer and conveying of the platform 5.

[0148] Optionally, the feeding mechanism 6 also includes a flux coating component disposed between the feeding roller group 61 and the second conveying mechanism 2. The flux coating component is used to coat flux onto each metal wire 100, thereby improving the welding strength between the metal wire 100 and the battery cell 200. The flux coating component can be any existing mechanism capable of applying flux to metal wires, such as applying flux to metal wires by immersion or spraying.

[0149] The foregoing has provided a sufficiently detailed and specific description of this application. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within the protection scope of this application. The scope of protection claimed in this application is defined by the claims, and not by the above descriptions in the embodiments.
