Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 1-7, an embodiment of the application provides a combined fixture, which includes a cell fixture 1 and an auxiliary fixture. The battery cell jig 1 is provided with a clamping assembly for clamping the battery cell, and the battery cell jig 1 is also provided with a containing space 101, such as a containing groove, for containing the auxiliary jig. The auxiliary fixture is used for clamping components to be connected with the battery cell, such as a switching sheet and a top cover. The auxiliary jig can be provided with one or a plurality of auxiliary jigs. For example, one for holding the adapter plate and the other for holding the top cover. The auxiliary jig can be embedded into the accommodating space 101 on the battery cell jig 1, which is equivalent to being combined with the battery cell jig 1, so that the positions of the battery cells and the parts to be connected are opposite and matched, and the production operation can be performed. And the auxiliary jig and the battery cell jig 1 can be arranged in a separable manner, for example, the auxiliary jig and the battery cell jig 1 can be detached or arranged in a separable manner (namely, two independent components), so that the auxiliary jig and the battery cell jig 1 can be combined together or separated. Therefore, the battery cell jig 1 can be combined with different auxiliary jigs, and the battery cells can be switched between different working procedures without replacing the jigs.

Specifically, when the electric core jig 1 and the auxiliary jig are combined together, the position matching requirement that the electric core is connected with other parts is met, the production and manufacturing conditions are met, and the connection operation can be performed. After the manufacturing operation of the procedure is finished, the auxiliary jig releases the clamping of the components such as the switching sheet or the top cover, and is separated from the cell jig 1 by taking out the accommodating space 101 on the cell jig 1. The battery cell jig 1 can directly enter the next process with the battery cell, for example, the battery cell jig 1 can be spliced with an auxiliary jig of the next process to manufacture the next process, and after the process is finished, the battery cell jig 1 is separated from the auxiliary jig of the process and can directly enter the next process.

So set up, electric core and wait to connect parts such as change piece and top cap, carry out the centre gripping of classifying through electric core tool 1 and auxiliary jig and fix, and two kinds of tools can splice also separable, electric core tool 1 can regard as general tool, after certain process and auxiliary jig separate, can bring electric core direct movement to next process, carry out the amalgamation or separate through electric core tool and auxiliary jig on different processes, make electric core through same tool circulation between different processes and accomplish the process preparation, that is electric core need not to change the tool when switching the process, need not to carry, electric core can remove through same electric core tool on incessant production conveying line and circulate fast between a plurality of different processes, whole in-process electric core need not to carry, not only simplified the tool in the whole manufacturing process and many, numerous and diverse degree, and showing the reduction electric core transport frequency, make electric core can all can be moved on same incessant production line and circulate, can accomplish through the tool, the processing efficiency has been avoided producing the battery to have been done, and the battery is damaged in the current processing efficiency is avoided, and the current technique is damaged, and the handling is difficult to be produced, the battery is easy to have solved and the handling quality is damaged in the battery is easy to the processing.

In order to facilitate the split and separation of the battery cell jig 1 and the auxiliary jig, the two are separate members, one of the two members moves, so that the split can be realized by enabling the auxiliary jig to enter the accommodating space 101 on the battery cell jig 1, and the split can be realized by directly moving the auxiliary jig out of the accommodating space 101.

In battery fabrication, the battery cells need to be welded to the tabs and the top cover, which is also an essential process requiring the connection of different components. Therefore, when the auxiliary jig is provided with one, it is the first jig 21 for holding the battery transfer sheet, or the second jig 41 that can be used for holding the battery top cover. When the auxiliary jigs are provided with at least two, the at least two auxiliary jigs include a first jig 21 for holding the battery conversion sheet and a second jig 41 for holding the battery top cover. The first clamp 21 and the second clamp 41 are matched with the accommodating space 101 on the battery cell jig 1, namely, the sizes of the first clamp and the second clamp are matched with the battery cell jig 1, so that when the clamp is located in the accommodating space 101, the battery cell and the component such as the switching piece or the top cover can be located at the matched position in alignment, and the welding can be directly performed without position adjustment. The first clamp 21 and the second clamp 41 can be independently combined with and separated from the cell jig 1.

When the auxiliary fixture comprises the first fixture 21 and the second fixture 41, the battery cell fixture 1 is spliced with the first fixture 21 and the second fixture 41 in sequence. Therefore, at least in the welding process, the welding of the battery cell and the switching sheet and/or the top cover is realized on the basis of not carrying the battery cell by the splicing and the separating of the battery cell jig 1 and the auxiliary jig. The fixture structure required by the welding procedure is simplified, the battery cells do not need to be switched among different fixtures, the battery cells are prevented from being damaged, and the welding efficiency is improved.

The embodiment of the application also provides a jig system, which comprises the combined jig and the conveying device, wherein the conveying device is used for driving the auxiliary jig and/or the battery core jig 1 to move, so that the battery core jig 1 and the auxiliary jig can be close to each other and can be far away from each other, and the split and the separation of the battery core jig 1 and the auxiliary jig are realized. So set up, this tool system not only possesses the technological effect that above-mentioned combination tool possessed, and through conveyor's drive, two kinds of tools dynamic combination and separation are very convenient for use in production, improve production efficiency.

The combination and separation of the battery cell jig 1 and the auxiliary jig can be realized by moving the battery cell jig 1 to be close to or far away from the auxiliary jig, or by moving the auxiliary jig to be close to or far away from the battery cell jig 1. The conveying device can be used for driving the battery cell 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 battery cell jig 1.

Taking the case that the auxiliary fixture moves to be close to or far from the battery cell fixture 1 as an example, when the auxiliary fixture is provided with at least two fixtures and comprises a first fixture 21 and a second fixture 41, the first fixture 21 and the second fixture 41 can be moved by the same group of mechanisms, so that the two fixtures are respectively spliced with the battery cell fixture 1. That is, the same conveying device alternately drives at least two auxiliary jigs to be close to the battery core jig 1, so that the at least two auxiliary jigs are spliced with the battery core jig successively.

The conveying device may also include a first conveying tool 3 for driving the first fixture 21 to move, and a second conveying tool 5 for driving the second fixture 41 to move, so that the first fixture 21 and the second fixture 41 can move independently and approach or separate from the cell fixture 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.

For example, in some embodiments, the fixture system further includes a conveying mechanism 6, the conveying mechanism 6 is used for driving the battery cell fixture 1 to move, and the first fixture 21 and the second fixture 41 are arranged along the extending direction of the conveying mechanism 6 and can be close to the battery cell fixture 1 under the driving of the conveying fixture, respectively, so as to be combined with the battery cell fixture 1 on the conveying mechanism 6. Then, after receiving the battery cell, the battery cell jig 1 may be combined with the first clamp 21 at the first position to connect the battery cell with the adapter piece, and then the battery cell jig 1 moves to the second position with the battery cell and is combined with the second clamp 41 to connect the battery cell with the top cover.

The conveying mechanism 6 may be a linear module, a motor and conveying belt assembly, a cylinder and guide rail assembly, etc., and may be a conveying line.

And based on the core idea of the application: the battery core does not need to switch the jig, and the same battery core jig 1 moves on the same uninterrupted production and conveying line to circulate among a plurality of different procedures, so that the production and manufacturing efficiency is improved. In some embodiments, in the battery production system, the conveying mechanism 6 is formed by a production conveying line for conveying the battery cells between different processes, and the battery cell jig 1 moves on the production conveying line and passes through multiple processes. The stations of different processes can be said to be arranged along the production conveying line, and auxiliary jigs required by the processes and conveying tools for driving the auxiliary jigs to be close to the battery core jigs 1 are arranged at the process positions where the auxiliary jigs are required. It can also be said that the auxiliary jigs of different processes are arranged along the extending direction of the production conveyor line as well as the moving direction of the battery cell jig 1. The manufacturing system of each process for welding or other processing the battery cells and other components is also arranged on the corresponding station. Therefore, the battery cells are clamped by the same battery cell jig and are conveyed by the same production conveying line together, and the battery cells can be sequentially conveyed to each station to finish processing and manufacturing. The production transfer chain is the transfer chain of a whole, and the concatenation is all processing stations, need not to be interrupted, also can say that each station is by a whole production transfer chain concatenation, and the battery core need not to change the tool, also need not to change the transfer chain, and the battery core tool moves from the head end to the tail end with the battery core, through all processing stations, and whole in-process need not to carry out the tool and switches, need not to carry out the battery core transport, can carry out the battery core preparation fast and smoothly, has not only simplified the structure, and has simplified the preparation loaded down with trivial details degree, is showing improvement production efficiency.

Of course, in some other embodiments, the auxiliary jigs may not be arranged along the extending direction of the production line, and may be arranged along other directions having an included angle with the extending direction of the production line. For example, the production conveyor line extends along a horizontal first direction, and the plurality of auxiliary jigs are arranged along a horizontal second direction perpendicular to the extension direction of the production conveyor line (may be located on one side of the production conveyor line or may be distributed on two sides of the production conveyor line), or are arranged along a vertical direction or other oblique directions.

At least two clamping positions are arranged on the first clamp 21, at least two switching pieces are clamped, and the two switching pieces are in a group and are respectively connected with the positive electrode lug and the negative electrode lug of the battery cell. The second clamp 41 clamps at least one top cover, and the single top cover is connected with the positive and negative lugs of the battery cell.

Typically, two sets of cells are provided within the battery to expand capacity. Therefore, as shown in fig. 2, in some embodiments, the cell fixture 1 has at least two sets of clamping assemblies for clamping at least two sets of cells, and a receiving space 101 for receiving the auxiliary fixture is provided between the at least two sets of clamping assemblies. At least two groups of electric cores are oppositely arranged on the electric core jig 1, and the head ends face the accommodating space 101. The lugs of the two groups of electric cores are connected with the switching piece or the top cover on the same clamp. And after the welding is finished, moving the two groups of electric cores to the upper part of the top cover, and carrying out core combining operation to realize the combined manufacturing of the two groups of electric cores and the top cover of the battery.

The auxiliary jig and the battery cell jig 1 can be spliced and separated in a horizontal movement mode, and can be embedded into or moved out of the accommodating space 101 of the battery cell jig 1, or can be embedded into or moved out of the accommodating space 101 of the battery cell jig 1 in a lifting movement mode. To avoid interference, the lifting and moving mode can be used first. The conveying device can be a horizontal driving mechanism, a lifting driving mechanism or a combination of the two.

For improving the manufacturing efficiency, at least two groups of auxiliary jigs used alternately can be arranged on the same station, for example, when one group receives the parts connected with the battery cells, the other group is spliced with the battery cell jig 1.

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 close to the cell fixture 1 alternately, so that the at least two groups of first clamps 21 are used alternately. 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 cell fixture 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 that drives the first clamp 21 to move in the horizontal first direction or the second direction, and a first jacking mechanism 22 that drives 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 31, a first transmission assembly 32 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 21 opposite to the receiving space 101 is also right below the receiving space 101). After the first fixture unit 2 moves to the welding position, the first jacking mechanism 22 drives the first fixture 21 to move upwards, so that the first fixture 21 and the cell fixture 1 can be spliced. After the welding, the first jig 21 is lowered to be separated from the accommodating 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 21 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 21 goes up and down, can accomplish amalgamation and separation with electric core tool 1, and overall design is smooth and simple and convenient, quick, does benefit to raise the efficiency. Meanwhile, the first clamps 21 can be used alternately, so that the efficiency is improved, the requirements 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 of the first jig units 2 that perform the reverse movement, the two first jigs 21 are arranged in the movement direction, and at least one of the two first jacking mechanisms 22 is located on one side of the first jig 21 perpendicular to the movement direction, so that an avoidance space is formed below the first jig 21. As shown in fig. 5, the first lifting mechanism 22 and the first clamp 21 may be provided in an inverted L shape. So that a space is formed right under the first clamp 21 to let another set of the first clamp units 2 pass. In this way, one of the two groups of first clamps 21 can move up and down to avoid the other group of first clamps 21 in height, and the two groups of first clamps can smoothly realize the reverse staggered movement during the 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 21 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 21 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.

In the same way, the second conveying tool 5 can be arranged in the same structure, so that the structure is simplified, and the space occupation is reduced. As shown in fig. 6, the second jigs 41 and the second jacking mechanism are provided one-to-one, and form the second jig unit 4. The second power mechanism of the second conveying tool 5 comprises a second driving device 51, a third transmission assembly 52 and a fourth transmission assembly 53, 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 is arranged on the third transmission assembly 52, and at least one group of second clamp units 4 is arranged on the fourth transmission assembly 53, so that at least two groups of second clamp units 4 can move reversely.

In each two or any two groups of second clamp units 4 that perform reverse movement, two groups of second clamps 41 are arranged in the movement direction, and at least one of the two groups of second lifting mechanisms is located at one side of the second clamp 41 perpendicular to the movement direction, so that an avoidance space is formed below the second clamp 41. As shown in fig. 5, the second lifting mechanism and the second clamp 41 may be provided in an inverted L shape. So that a space is formed right under the second jig 41 to let another set of the second jig units 4 pass.

The two sets of second lifting mechanisms may be arranged on both sides of the moving direction to avoid mutual interference. That is, one of the two sets of second lifting mechanisms is located on a first side, such as the left side, of the first set of second jigs 41 perpendicular to the moving direction, and the other is located on a second side, such as the right side, of the second set of second jigs 41 perpendicular to the moving direction. The two groups of second jacking mechanisms are arranged at two sides in a row and are opposite in interval. The second lifting mechanism and the second clamp 41 may be provided in an inverted L-shape.

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 and the battery cell jig 1 are spliced and separated 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.

So, second climbing mechanism and second anchor clamps 41 set up one to one, form second anchor clamps unit 4 and carry out the bulk movement, and two at least groups of second anchor clamps unit 4 are through reverse removal, can be in connecing between material level and the welding position quick alternation, and when second anchor clamps unit 4 moved to the welding position, second climbing mechanism drive second anchor clamps 41 goes up and down, can accomplish amalgamation and the separation with electric core tool 1, and overall design is smooth and simple and convenient, quick, does benefit to raise the efficiency. The second clamps 41 can be used alternately, so that the efficiency is improved, the requirement of the two groups of second clamp units 4 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.

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.

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.

In the first conveying tool 3, a guide structure for guiding the first jig unit 2 is further provided.

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 that the holding space 101 is completely moved out, and the interference of the cell extraction is avoided. 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.
