Meanwhile, the universal jig 1 and the auxiliary jig can be spliced and separated. For example, they may be removable or separate (i.e., as two separate pieces). As a preferred embodiment, the universal fixture 1 and the auxiliary fixture are two independent components, which can be spliced together or separated for independent movement. The auxiliary jig can be provided with one or a plurality of auxiliary jigs. Any one of the auxiliary jigs can be independently spliced with the universal jig 1 to be combined. The universal jig 1 can be combined with a plurality of auxiliary jigs, respectively.

So, the part main part and the to-be-connected piece that needs to set up to the part main part are fixed through two kinds of tools that independently set up respectively, namely general tool 1 and auxiliary jig, and general tool 1 can splice also can separate with auxiliary jig. Then, the general jig 1 and the auxiliary jig are spliced together, the positions of the part main body and the part to be connected can be matched for production and manufacture, after the manufacture treatment is finished, the auxiliary jig can be separated from the general jig 1 after loosening the clamping of the part to be connected, the general jig 1 can directly move to a station of the next processing procedure with the part main body without switching the jig, and can be spliced with the auxiliary jig of the next procedure continuously for the manufacture of the next procedure, after the processing of the procedure is finished, the general jig 1 can directly move to the subsequent further processing procedure with the part main body, the part main body is subjected to procedure circulation without replacing the jig, and the carrying is not needed.

Therefore, the conveyor line in the present application is a general conveyor line 6, and only one conveyor line may be provided. A plurality of different processing stations, such as a welding station, a dust removing station 605, a rubberizing station, a detecting station 606, etc. (other stations are also possible) are arranged on the same general conveyor line 6, and a plurality of processing steps are integrated on the general conveyor line 6, wherein at least part of the stations are provided with auxiliary jigs, so to speak, the auxiliary jigs are provided with a plurality of auxiliary jigs and distributed on different stations. The universal fixture 1 for fixing the component main body is arranged on the universal conveying line 6, and the universal fixture 1 carries the component main body to sequentially pass through a plurality of stations for different processing and manufacturing under the conveying of the universal conveying line 6. The general jig 1 moves along the general conveying line 6 along the part main body, and in the stations passing through a plurality of processing procedures, the auxiliary jig can be combined with the auxiliary jig of the stations, the position matching requirement of the part main body and a part to be connected is met, the production and the manufacturing of the procedure can be carried out, the general conveying line 6 is separated from the auxiliary jig of the stations after the manufacturing is finished, the general jig 1 is continuously conveyed by the general conveying line 6, and the part main body can continuously enter the station of the next manufacturing procedure along the general conveying line 6.

So set up, the part main part can circulate fast through a general tool 1 under the transportation of a general transfer chain 6 between the station of different processing procedures, can follow the station of first processing procedure on an incessant general transfer chain 6, move (indicate can not carry out the transfer chain and switch, and not inject the continuous removal) to the station of last process, through the amalgamation and the separation with auxiliary jig on different stations in proper order, can accomplish the processing preparation of each process in proper order, can accomplish the operation that most even all need carry out processing in the part main part under the centre gripping of same tool, whole in-process, the part main part need not to carry out the production line and switch, also need not to carry out the tool and switch, thereby showing the overall structure of simplifying production system, reduce production line and tool quantity, reduce the loaded down with trivial details degree of preparation process, improve production preparation efficiency, the production system among the prior art, when the part main part switches processing procedures, need change production line and used tool and lead to the loaded down with trivial details and slow problem of preparation process.

The general jig 1 and the auxiliary jig can be spliced and separated, and can be detachably connected, or can be arranged as independent members. In the embodiment of detachable connection, the universal fixture 1 and the auxiliary fixture may be combined together first and then driven by the disassembling mechanism to separate the two. In order to improve the manufacturing efficiency, in the preferred embodiment, the universal jig 1 and the auxiliary jig are provided as independent members. The two can be spliced and combined by being close to each other, and can be separated by being far away from each other.

In some cases, the part to be joined needs to be fixed to the middle or non-edge position of the component body, which is also why a jig is provided in the prior art to fix the component body and the part to be joined, respectively. In order to solve the problem, the universal fixture 1 is provided with the embedding space 101 for accommodating the auxiliary fixture, the auxiliary fixture enters the embedding space 101, so that the position matching requirement of the to-be-connected piece and the component main body can be met, and the auxiliary fixture is separated from the embedding space 101, so that the two fixtures can be separated.

When the fitting space 101 extends to the edge of the universal jig 1, and the edge has an opening, the auxiliary jig and the universal jig 1 are close to each other, and the auxiliary jig can be inserted into the fitting space 101 from one side of the universal jig 1, or the auxiliary jig and the universal jig 1 are close to each other in the thickness direction, and the auxiliary jig moves vertically with respect to the fitting space 101, and is fitted into the fitting space 101 from directly above or directly below the fitting space 101. When the fitting space 101 does not extend to the edge of the universal jig 1 and there is no opening at the edge, the auxiliary jig and the universal jig 1 are close to each other in the thickness direction, and the auxiliary jig is fitted into the fitting space 101 from directly above or directly below the fitting space 101.

On the station with the auxiliary jig, the common jig 1 and the auxiliary jig can be spliced and separated, and can be realized by moving the common jig 1 to be close to or far from the auxiliary jig, or by moving the auxiliary jig to be close to or far from the common jig 1. In some embodiments, the production system is further provided with a conveying tool, and the conveying tool can be used for driving the universal jig 1 to move to be close to or far away from the auxiliary jig, and can also be used for driving the auxiliary jig to be close to or far away from the universal jig 1.

In some embodiments, as shown in fig. 2, the universal fixture 1 is disposed on the universal conveying line 6, and moves along the universal conveying line 6, while the plurality of stations are arranged along the extending direction of the universal conveying line 6, and on part of the stations, the auxiliary fixture is disposed on one side or above or below the universal conveying line 6, and matches the conveying fixture. The auxiliary jig is driven by the conveying tool to be close to the universal jig 1 positioned on the universal conveying line 6, so that the auxiliary jig and the universal jig 1 are spliced and combined together, the production, processing and manufacturing on the station are completed, the auxiliary jig is driven by the conveying tool to be far away from the universal jig 1 positioned on the universal conveying line 6, the universal jig 1 is separated from the auxiliary jig, and the universal jig 1 can be moved to the next station after continuing to move along the universal conveying line 6.

So set up, general tool 1 only need carry by general transfer chain 6 and remove can, need not on general transfer chain 6 or on a certain station that says so, produce the removal of other directions again, the simplifying of the structure of being convenient for sets up, and general tool 1 in case with supplementary tool separation, can continue to move to next station, the return material loading of supplementary tool and the removal of general tool 1 can go on simultaneously, can further improve circulation speed and preparation efficiency.

Because in the whole manufacturing process, the part main body does not need to switch the jig, does not need to switch the conveying line, does not need to carry, and can move on the same uninterrupted universal conveying line 6 through the same universal jig 1, namely, can circulate among stations of a plurality of different processes, and improves the production and manufacturing efficiency. That is to say, the general-purpose conveying line 6 may be a circulation conveying line, and the general-purpose jig 1 may be circulated and reused. For example, the circulation line includes a production transport section 61, a return section 62, and a transfer section 63. The production conveying section 61 conveys the universal jig 1, so that the universal jig 1 receives the component main body and carries the component main body to circulate among a plurality of stations, processing and manufacturing of each process such as welding, dust removal, rubberizing, detection and the like are completed, and the processed component main body is unloaded at the unloading station 609 (a unloading mechanism such as a mechanical arm and the like is used for taking down the component main body on the universal jig 1). The reflow section 62 is used for reflowing the empty general jig 1, i.e. the empty general jig 1, which is used for blanking the finished component body, so that the empty general jig 1 moves to the initial station of the production and conveying section 61. Thus, the universal fixture 1 can flow circularly and be recycled, and can be always used on the universal conveying line 6, and the universal fixture is not required to be carried when being used for receiving and discharging materials.

The circulation conveying line can be an integral annular conveying line, the head end and the tail end of the backflow section 62 are provided with arc-shaped sections, and the arc-shaped sections are connected with the production conveying section 61, so that the universal fixture 1 can turn around, move from the production conveying section 61 to the backflow section 62 and also can move from the backflow section 62 to the production conveying section 61.

In some embodiments, the circulating conveyor line may be a split type annular conveyor line, the reflow section 62 includes a main body section and transfer sections 63 disposed at the front end and the rear end of the main body section, the transfer sections 63 at the rear end receive the empty general-purpose jig 1 conveyed by the general-purpose conveyor line 6 and convey it to the reflow main body section, and the transfer sections 63 at the front end receive the empty general-purpose jig 1 conveyed by the main body section and convey it to the production conveying section 61. For example, the production conveying section 61 and the return section 62 are arranged in the height direction to form a two-layer conveying structure, and the two transfer sections 63 are lifting conveying tables, which can be lifted and horizontally conveyed.

The sections of the various conveyor lines may be conveyor assemblies including power elements such as motors and conveyor elements such as conveyor belts, conveyor chains, etc., and when the transfer section 63 has a lifting function, the conveyor assemblies may be disposed on a lifting mechanism.

The production system can be used in various fields. Taking battery production as an example, when the production system is applied to battery production, the universal fixture 1 is used for clamping the battery core, the universal conveying line 6 is used for conveying the battery core, and the auxiliary fixture can be used for clamping to-be-connected pieces such as a top cover, a switching piece and the like to be arranged on the battery core, and also can be auxiliary machined pieces.

The plurality of stations on the universal conveyor line 6 may include any combination of a loading station 601, a welding station, a rubberizing station, a dust removal station 605, a detection station 606, and a blanking station 609. Of course, in a preferred embodiment, all of the above stations are included. And at least the welding station is provided with an auxiliary jig. When rubberizing on the utmost point ear of electric core, because the utmost point ear is the thin slice, easily pinches or buckle, needs auxiliary part to support utmost point ear position at least, consequently also can be provided with auxiliary jig on the rubberizing station.

So set up, in electric core production system, can only set up a universal transfer chain 6, with each processing station cluster, need not to set up a plurality of carousel formula production lines, through making the auxiliary jig on universal jig 1 and each station combine and separate, electric core can be carried by same transfer chain jointly under the carrying of same universal jig 1, the multiple station of route in proper order, and whole in-process need not to switch the tool, switches production line. Compared with the arrangement that one production system is provided with a plurality of scattered turntable type production lines in the prior art, the production system provided by the application remarkably simplifies the whole structure of the battery cell production system, reduces the number of production lines and universal jigs, reduces the complexity of the battery cell manufacturing process and improves the production efficiency.

The plurality of stations on the universal conveyor line 6 generally include a loading station 601, a welding station, a rubberizing station, a dust removal station 605, a detection station 606, a blanking station 609, and the like. The general jig 1 is provided with a clamping assembly capable of being opened and closed, and the feeding station 601 and the discharging station 609 are respectively provided with an opening and clamping mechanism for opening the clamping assembly.

Be provided with on the welding station and provide the welding auxiliary jig of welding connecting piece, drive the transport frock that the welding auxiliary jig removed, provide the auxiliary feeding mechanism of welding connecting piece to and carry out welded welding mechanism. The rubberizing station is provided with a rubberizing auxiliary jig serving as a processing auxiliary piece, a conveying tool for driving the rubberizing auxiliary jig to move and a rubberizing mechanism. The dust removal station 605 is provided with a dust removal device for removing dust from the battery cells. The detection station 606 is provided with a detection device, such as a CCD detection device, for detecting the weld. The blanking station 609 is provided with an opening mechanism and a battery core blanking mechanism for unloading the battery core on the universal fixture 1.

Specifically, as shown in fig. 2 and 4, the auxiliary jig at the welding station is referred to as a welding auxiliary jig. Because the battery cell needs to be welded with the transfer tab and the top cover, the welding auxiliary fixture comprises a first fixture 21 for clamping the battery transfer tab and a second fixture 41 for clamping the top cover of the battery. That is, the welding auxiliary jig at least includes a first auxiliary jig and a second auxiliary jig, the first auxiliary jig is the first jig 21, and the second auxiliary jig is the second jig 41. The first clamp 21 and the second clamp 41 are matched with the embedded space 101 on the universal jig, namely, the sizes of the first clamp and the second clamp are matched with the universal jig 1, so that when the clamps are located in the embedded space 101, the battery cell and the switching piece or the top cover can be located in aligned matched positions, and the welding can be directly carried out without position adjustment. The first jig 21 and the second jig 41 can each be individually combined with and separated from the universal jig 1.

The first clamp 21 and the second clamp 41 can be driven by the same conveying tool, so that the two clamps are respectively combined with the universal tool 1. That is, the same conveying tool alternately drives at least two auxiliary tools to approach the universal tool 1, so that the at least two auxiliary tools are combined with the universal tool 1 successively.

Alternatively, the first conveying tool includes a first conveying tool 3 for driving the first clamp 21 to move, and a second conveying tool 5 for driving the second clamp 41 to move, so that the first clamp 21 and the second clamp 41 can move independently, approaching or moving away from the universal tool 1. In this way, the feeding of the first clamp 21 and the second clamp 41 is facilitated to be separately provided, and is facilitated to be provided at different stations.

As shown in fig. 2 and 4, the first clamp 21 and the second clamp 41 are aligned along the extending direction of the common conveyor line 6, and form a first welding station 602 and a second welding station 604. That is, the first welding station 602 is provided with the first clamp 21, the first conveying tool 3, and the transfer sheet feeding mechanism. The second welding station 604 is provided with a second clamp 41, a second conveying tool 5 and a top cover feeding mechanism.

Of course, in some other embodiments, the plurality of welding auxiliary jigs may not be arranged along the extending direction of the universal conveying line 6, and may be arranged along other directions having an included angle with the extending direction of the universal conveying line 6. For example, the universal conveyor line 6 extends in a horizontal first direction, and the first clamp 21 and the second clamp 41 are arranged in a horizontal second direction (may be located on one side of the universal conveyor line 6 or may be distributed on both sides of the universal conveyor line 6) perpendicular to the extending direction of the universal conveyor line 6, or in a vertical direction or other oblique direction. Therefore, only one welding station can be arranged, and when the universal jig 1 is arranged on the welding station, the plurality of welding auxiliary jigs are spliced and separated with the universal jig 1 in sequence.

The tab of the battery core needs to be rubberized, and an auxiliary jig serving as a processing auxiliary piece can be arranged at a rubberizing station and is called rubberizing auxiliary jig. In some embodiments, it is desirable to apply a glue to the upper surface of the tab, as well as to the lower surface of the tab. The rubberizing stations may be provided with a lower rubberizing station 603 and an upper rubberizing station 607 arranged along the general conveyor line 6. The rubberizing auxiliary jig is provided with at least two, and is respectively arranged on the lower rubberizing station 603 and the upper rubberizing station 607. Specifically, the auxiliary fixture for rubberizing of the lower rubberizing station 603 includes or is a lamination element 7 for laminating the tab portion of the battery cell. The rubberizing auxiliary jig of the rubberizing station 607 comprises or is a support for supporting the tab portion of the battery cell.

In some embodiments, the upper surface rubberizing is divided into two rubberizing parts, one rubberizing part covers the upper surfaces of the lugs and the switching pieces, the connection between the lugs and the switching pieces is enhanced, and the other rubberizing part covers the end parts of the switching pieces and the partial areas of the top cover, so that the connection between the switching pieces and the top cover is enhanced. The rubberizing station may be provided with a lower rubberizing station 603 for rubberizing the lower surface of the cell tab, and an upper rubberizing station 607 and a soft connection rubberizing station 608 for rubberizing the upper surface of the cell tab. In this embodiment, the rubberizing auxiliary fixtures are provided on the lower rubberizing station 603, the upper rubberizing station 607 and the soft connection rubberizing station 608, respectively. It can also be said that the lower rubberizing station 603, the upper rubberizing station 607 and the flexible connection rubberizing station 608 are all provided with rubberizing auxiliary fixtures. The auxiliary jig of the upper rubberizing station 607 is a first supporting piece 8 for supporting the lug part of the battery cell, and the auxiliary jig of the soft connection rubberizing station 608 is a second supporting piece 9 for supporting the top cover.

The conveying tool for conveying each rubberizing auxiliary tool comprises a third conveying tool for driving the pressing piece 7 to move, a fourth conveying tool for driving the first supporting piece 8 to move and a fifth conveying tool for driving the second supporting piece 9 to move. The pressing piece 7, the first supporting piece 8 and the second supporting piece 9 are respectively or successively spliced or separated from the universal fixture 1 on the universal conveying line 6 under the driving of the corresponding conveying tools.

For example, the lower rubberizing station 603 is provided with a lamination part 7, a third conveying tool for driving the lamination part 7 to move, and a rubberizing mechanism; the upper rubberizing station 607 is provided with a first supporting piece 8, a fourth conveying tool for driving the first supporting piece 8 to move and a rubberizing mechanism; the flexible connection rubberizing station 608 is provided with a second supporting piece 9, a fifth conveying tool for driving the second supporting piece 9 to move and a rubberizing mechanism.

That is, in some embodiments, along the extending direction of the universal conveyor line 6, the feeding station 601, the first welding station 602, the lower rubberizing station 603, the second welding station 604, the dust removing station 605, the detecting station 606, the upper rubberizing station 607, the flexible connection rubberizing station 608, and the blanking station 609 are sequentially arranged. The general jig 1 sequentially passes through each station under the conveying of the general conveying line 6, and the auxiliary jigs are provided with five components, wherein the first auxiliary jig is a first clamp 21 and is arranged on a first welding station 602, the second auxiliary jig is a second clamp 41 and is arranged on a second welding station 604, the third auxiliary jig is a pressing piece 7 and is arranged on a lower rubberizing station 603, the fourth auxiliary jig is a first supporting piece 8 and is arranged on an upper rubberizing station 607, and the fifth auxiliary jig is a second supporting piece 9 and is arranged on a soft connection rubberizing station 608.

When the universal fixture 1 moves to the feeding station 601 along the universal conveying line 6, the clamping assembly is opened by the clamping opening mechanism, the first material carrying mechanism can also be said to be the battery cell feeding mechanism, the battery cell is moved to the clamping assembly on the universal fixture 1, then the clamping assembly is removed, the battery cell is clamped and fixed by the clamping assembly, and then the universal fixture 1 is moved to the first welding station 602. The first conveying tool 3 moves the first clamp 21 carrying the switching piece into the embedded space 101 on the universal jig 1, so that the first clamp 21 and the universal jig 1 are spliced together, the switching piece and the battery cell are matched at a position where welding is needed, and then welding is carried out. After the welding of the adapter piece, the first clamp 21 releases the clamping of the adapter piece, and then the adapter piece is moved out of the embedding space 101 of the universal fixture 1 under the driving of the first conveying fixture 3. The general jig 1 moves to the lower rubberizing station 603, the third conveying tool drives the lamination part 7 to move, so that the lamination part 7 moves downwards from the upper part of the general conveying line 6 to the lug part position of the battery cell (the local area of the lamination part 7 is matched with the embedded space 101 on the general jig 1 and can be embedded into the embedded space 101 to laminate the lug), and the rubberizing mechanism (can be marked as a first rubberizing mechanism) moves the gumming paper upwards from the lower part of the general conveying line 6 and is adhered to the lower surfaces of the lug and the transfer sheet to connect the lug and the transfer sheet.

And then the pressing piece 7 is removed, the universal fixture 1 moves to a second welding station 604 with the battery core, the second conveying tool 5 moves the second fixture 41 with the top cover into the embedding space 101 of the universal fixture 1, so that the second fixture 41 and the universal fixture 1 are spliced together, and the top cover and the battery core are matched in position for welding. After the welding, the second clamp 41 releases the clamping of the top cover and is removed under the drive of the second conveying tool 5. The universal fixture 1 moves to the dust removal station 605 with the cells already provided with a top cover. The dust removing device removes dust from the battery cell, then the universal jig 1 moves to the detection station 606 with the battery cell, the detection device detects the battery cell, for example, quality detection is performed on the welding seam, and after the detection, the universal jig 1 moves to the upper rubberizing station 607 with the battery cell.

The fourth conveying tool drives the first supporting piece 8 to move upwards from the lower part of the general conveying line 6 to be attached to the top cover (the local area of the first supporting piece 8 is matched with the embedded space 101 on the general jig 1, and the first supporting piece can be embedded into the embedded space 101 to attach to the top cover), and the support of the lug and the adapter piece area is realized through the support of the top cover. The rubberizing mechanism (can be marked as a second rubberizing mechanism) moves the gummed paper downwards from the upper part of the general conveyor line 6, attaches to the upper surfaces of the lugs and the rotating plates, and then the first support is removed, so that rubberizing is completed. The universal fixture 1 moves to the flexible connection rubberizing station 608 with the battery cell, and the fifth conveying tool drives the second supporting piece 9 to be spliced with the universal fixture 1, namely drives the second supporting piece 9 to move upwards from the lower part of the universal conveying line 6 to be attached to the top cover. The rubberizing mechanism moves the gummed paper downwards from the upper part of the general conveying line 6 and is attached to the upper surfaces of the transfer sheet and the top cover. Then, the second supporting piece 9 is removed, the universal fixture 1 moves to the blanking station 609, the clamping assembly on the universal fixture 1 is opened by the clamping opening mechanism of the blanking station 609, and the battery cell is taken out by the battery cell blanking mechanism.

Thus, the processing procedure of the battery cell is completed. Therefore, the operation that the battery cell can be processed in multiple ways through the universal fixture 1 under the conveying of the same universal conveying line 6 is realized, the fixture for clamping the battery cell is not required to be switched in the manufacturing process, the conveying line is not required to be switched, the battery cell is not required to be conveyed, and the production efficiency is remarkably improved.

In order to improve the manufacturing efficiency, at least two groups of auxiliary jigs used alternately can be arranged on a station provided with the auxiliary jigs, such as a welding station, and one group is combined with the universal jig 1 when the other group receives the parts connected with the battery cells.

For example, the first clamps 21 are provided with at least two groups, and the first conveying tool 3 drives the at least two groups of first clamps 21 to be alternately close to the universal tool 1, so that the at least two groups of first clamps 21 are alternately used. Similarly, at least two groups of second clamps 41 may be provided, and the second conveying tool 5 drives at least two groups of second clamps 41 to be close to the universal tool 1 alternately, so that at least two groups of second clamps 41 are used alternately.

In some embodiments, the first conveying tool 3 includes a first power set that drives the first clamp 21 to move in a first direction, and a second power set that drives the first clamp 21 to move in a second direction. So, the first clamp 21 can move in two directions, so that different first clamps 21 can be used alternately, and avoidance with other parts can be facilitated in the moving process of the first clamp 21, so that interference is avoided.

For example, the first conveying tool 3 includes a first power mechanism for driving the first clamp 21 to move in the horizontal first direction or the second direction, and a first lifting mechanism for driving the first clamp 21 to move up and down. The first conveying tool 3 may include a first power mechanism for driving the first clamp 21 to move in a first horizontal direction and a second power mechanism for driving the first clamp 21 to move in a second horizontal direction.

Similarly, the second conveying tool 5 includes a first power unit for driving the first clamp 21 to move in the first direction, and a second power unit for driving the first clamp 21 to move in the second direction. However, in the process of loading the top cover, interference with the adaptor already welded on the battery cell is easy to occur, so in a preferred embodiment, the second conveying tool 5 includes a second power mechanism for driving the second fixture 41 to move along the first or second horizontal direction, and a second lifting mechanism for driving the second fixture 41 to move up and down.

In some embodiments, the first jigs 21 and the first jacking mechanisms 22 are provided one-to-one, and form the first jig unit 2. The first power mechanism comprises a first driving device, a first transmission assembly and a second transmission assembly 33, wherein the first driving device 31 is respectively connected with at least two groups of first clamp units 2 through the first transmission assembly 32 and the second transmission assembly 33, so that the at least two groups of first clamp units 2 are distributed on different transmission assemblies, for example, at least one group of first clamp units 2 are arranged on the first transmission assembly 32, and at least one group of first clamp units 2 are arranged on the second transmission assembly 33, so that at least two groups of first clamp units 2 can move reversely.

When the first transmission assembly 32 drives the first group of the first clamp units 2 to move to the receiving position, the second transmission assembly 33 drives the second group of the first clamp units 2 to synchronously and reversely move, so that the second group of the first clamp units 2 moves to the welding position (the position of the first clamp opposite to the fitting space 101 is also right below the fitting space 101). After the first clamp unit 2 moves to the welding position, the first clamp is driven to move upwards by the first jacking mechanism 22, so that the first clamp and the universal fixture 1 can be combined. After the welding, the first jig is lowered to be separated from the fitting space 101. When the second transmission assembly 33 drives the second group of the first fixture units 2 to leave the welding position, the first transmission assembly 32 drives the first group of the first fixture units 2 to synchronously and reversely move, so that the first group of the first fixture units are close to the welding position and far away from the receiving position.

So, first climbing mechanism 22 and first anchor clamps set up one to one, form first anchor clamps unit 2 and carry out the bulk movement, and two at least groups of first anchor clamps unit 2 are through reverse removal, can be in connecing between material level and the welding position quick alternation, and when first anchor clamps unit 2 moved to the welding position, first climbing mechanism 22 drive first anchor clamps go up and down, can accomplish the combination and the separation with general tool 1, and integrated design is smooth and simple and convenient, quick, does benefit to raise the efficiency. Meanwhile, the first clamps can be used alternately, the efficiency is improved, the requirement of the two groups of first clamp units 2 on reverse movement can be met through one driving source, the structure can be simplified, the occupied requirement on space is reduced, and the arrangement is convenient.

In each two or any two groups of the first clamp units 2 that move in the opposite direction, the two groups of the first clamps are arranged in the moving direction, and at least one of the two groups of the first jacking mechanisms 22 is located at one side of the first clamp perpendicular to the moving direction, so that an avoidance space is formed below the first clamp. As shown in fig. 8, the first lifting mechanism 22 and the first clamp may be in an inverted L-shaped configuration. So that a space is formed right under the first jig to avoid the passage of another group of the first jig units 2. Therefore, one of the two groups of first clamps can move up and down to avoid the other group of first clamps in height, and the two groups of first clamps can move in a reverse staggered manner smoothly during horizontal movement.

Of course, two sets of first lifting mechanisms 22 may be arranged on both sides of the moving direction to avoid interference. For example, one of the two sets of first jacking mechanisms 22 is located on a first side, such as the left side, of the first set of first clamps perpendicular to the moving direction, and the other is located on a second side, such as the right side, of the second set of first clamps perpendicular to the moving direction. The two groups of first jacking mechanisms 22 are arranged at two sides in a row and are opposite in interval.

And the second conveying tool can be arranged in the same structure, so that the structure is simplified, and the space occupation is reduced. As shown in fig. 9, the second jigs and the second jacking mechanism are provided one-to-one, and the second jig unit 4 is formed. The second power mechanism of the second conveying tool comprises a second driving device 51, a third transmission assembly 52 and a fourth transmission assembly 53, wherein the second driving device 51 is respectively connected with at least two groups of second clamp units 4 through the third transmission assembly 52 and the fourth transmission assembly 53, so that the at least two groups of second clamp units 4 are distributed on different transmission assemblies, for example, at least one group of second clamp units 4 are arranged on the third transmission assembly 52, and at least one group of second clamp units 4 are arranged on the fourth transmission assembly 53, so that at least two groups of second clamp units 4 can move reversely.

In every two groups or any two groups of second clamp units 4 which move reversely, the two groups of second clamps are arranged along the moving direction, and at least one of the two groups of second jacking mechanisms is positioned at one side of the second clamp which is vertical to the moving direction, for example, the second jacking mechanism and the second clamp 41 can be arranged in an inverted L shape, so that an avoidance space is formed below the second clamp 41 and can be used for the other group of second clamp units 4 to pass through. When the third transmission assembly 52 drives the first group of second clamps 41 to move to the receiving position, the fourth transmission assembly 53 drives the second group of second clamp units 4 to move reversely to the welding position, and then the second transmission assembly is combined with and separated from the universal fixture 1 under the action of the second jacking mechanism. When the fourth transmission assembly 53 drives the second group of second clamp units 4 to leave the welding position, the third transmission assembly 52 drives the first group of second clamp units 4 to reversely move to be close to the welding position and far away from the receiving position.

Taking the first conveying tool as an example for explanation, the moving direction of the moving end of the second transmission assembly 33 is parallel and opposite to the moving direction of the moving end of the first transmission assembly 32. Specifically, as shown in fig. 6, the first transmission assembly 32 may be a screw nut assembly or a belt assembly. The first clamp unit 2 includes a base 23, the first jacking mechanism 22 is provided on the base 23, and the first clamp is provided at the driving end of the first jacking mechanism 22. The first clamp unit 2, which is connected to the first transmission assembly 32, has its base 23 connected to a transmission member of the first transmission assembly 32, such as a nut in a lead screw nut assembly, or a belt in a belt assembly. Is moved by the first driving means 31.

While the second transmission assembly 33 includes a first link 331 and a first transmission belt 332, one of the upper and lower sections of the first transmission belt 332 is connected to the first driving device 31 through the first link 331, and the other is connected to the base 23 of the second group first gripper unit 2. Thus, under the driving of the first driving device 31, the first connecting piece 331 drives the up-going section or the down-going section of the first driving belt 332 to move in the same direction as the moving direction of the first driving assembly 32, and the down-going section or the up-going section of the first driving belt 332 drives the second group of the first clamp units 2 to move in the opposite direction to the first group of the first clamp units 2. In this way, the effect of driving at least two groups of the first clamp units 2 to move reversely by one power source is achieved.

Also, the structural arrangement of the third transmission assembly 52 and the fourth transmission assembly 53 may be the same as the structural arrangement of the first transmission assembly and the second transmission assembly.

The second clamp unit 4 includes a base on which the second jacking mechanism is provided, and the second clamp 41 is provided at the driving end of the second jacking mechanism. The second clamp unit 4 connected to the third transmission assembly 52 has its base connected to a transmission member of the third transmission assembly 52, such as a nut in a lead screw nut assembly, or a belt in a belt assembly, and is moved by the second driving device 51.

And the fourth transmission assembly 53 includes a second connection 531 and a second transmission belt 532, one of the upper and lower sections of the second transmission belt 532 is connected to the second driving device 51 through the second connection 531, and the other is connected to the base 23 of the other group of the second clamp units 4. Thus, under the driving of the second driving device 51, the second connecting piece 531 drives the upward section or the downward section of the second driving belt 532 to move in the same direction as the moving direction of the third driving assembly 52 and the first set of the second clamp units 4, and the downward section or the upward section of the first driving belt 332 moves in the opposite direction to the moving direction of the second set of the first clamp units 2.

Of course, in other embodiments, the second transmission assembly 33 and the fourth transmission assembly 53 may have other structures, such as a link structure, where the second link drives the third link to move in the opposite direction when the first link moves in the opposite direction.

The driving devices in the first lifting mechanism 22 and the second lifting mechanism may be air cylinders, motors, or the like. For example, the combination of the cylinder and the guide rail can be adopted, and the combination of the motor lead screw can also be adopted.

In some embodiments, on the universal fixture 1, two sets of clamping assemblies are one unit, and in each unit, a space is formed between the two sets of clamping assemblies, and the space forms a fitting space 101 for accommodating the auxiliary fixture.

On the universal fixture 1, the clamping assembly at least comprises a group of clamping baffles which can be opened and closed. In order to prevent the battery cell from being askew, the positioning accuracy of the battery cell is ensured, and the clamping assembly comprises two groups of clamping baffles which can be opened and closed.

In some embodiments, the clamping assembly includes a first barrier 102, a limit barrier 104, and a second barrier 103. The first shutters 102 are provided with at least two opposing and spaced apart in the first direction, and are disposed to move in the first direction such that the at least two first shutters 102 can open and close. The second baffle 103 and the limit baffle 104 are arranged at intervals along the second direction, and the second baffle 103 is arranged in a moving way along the second direction, so that the second baffle 103 and the limit baffle 104 can be opened and closed.

The fitting space 101 is located at one side of the clamping assembly and between the two sets of clamping assemblies. As shown in fig. 5, the fitting space 101 is located in the second direction between the two limit stops 104. The limit stop 104 partially protrudes above the engaging space 101.

Thus, the limit stop 104 is movably disposed in the second direction. Thus, when the top cover and the battery cell are welded, the limit baffle 104 can avoid when the battery cell is taken out, and the limit baffle 104 and the top cover are prevented from interfering to prevent the battery cell from being taken out.

In some embodiments, the limit stop 104 is disposed in conjunction with the first stop 102. When the limit baffles 104 are provided with two of them arranged at intervals in the first direction, the limit baffles 104 are connected one-to-one with the first baffles 102. When the first baffles 102 move to open the two first baffles 102, the limit baffles 104 move along with the first baffles, so as to thoroughly move out of the embedded space 101, and avoid interference with the extraction of the battery cells. In this way, the structure can be simplified, and no additional power mechanism is required to be arranged due to the movement of the limit baffle 104.

The clamping assembly is opened and closed by the opening and clamping mechanism. The clamping opening mechanism is separated from the universal jig 1. Therefore, the universal fixture 1 is free of power parts, does not need to be connected with wires, pipelines and the like, is convenient to move and is convenient to transfer among different procedures. The clamping opening mechanism is arranged beside the general conveying line 6 and arranged on the feeding station 601 and the discharging station 609.
