According to a first aspect of embodiments of the present application, a molding mechanism is provided, and the structure and the operation principle of the molding mechanism will be specifically described below with reference to fig. 1 to 7.

In an embodiment, the forming mechanism includes a first locating member 28 and a second locating member 30. The first and second positioning members 28, 30 are disposed opposite one another.

In one example, a direction in which the first positioning member 28 and the second positioning member 30 are opposed to each other is perpendicular to a direction in which the third positioning member 10 and the fourth positioning member 18 (to be described later) are opposed to each other. For example, the first positioning member 28 and the second positioning member 30 are opposed to each other in the left-right direction F2 perpendicular to the front-rear direction F1. As shown in fig. 4, the left-right direction F2 here is the vertical direction shown in fig. 4.

Specifically, the first positioning member 28 and the second positioning member 30 are used to place a plurality of cells stacked in sequence, and the direction in which the first positioning member 28 and the second positioning member 30 are opposed is perpendicular to the stacking direction of the plurality of cells. In combination with the above example, the stacking direction of the plurality of battery cells is the front-rear direction F1, and the facing direction of the first positioning member 28 and the second positioning member 30 is the left-right direction F2.

Wherein the distance between the first positioning member 28 and the second positioning member 30 is configured to be increased and decreased for positioning the battery cell disposed between the third positioning member 10 and the fourth positioning member 18. In the embodiment, the multiple battery cells are sequentially arranged between the third positioning member 10 and the fourth positioning member 18, and the first positioning member 28 and the second positioning member 30 are arranged to ensure that the multiple battery cells are kept flush in the left-right direction F2. That is, the adjustment of the distance between the first positioning member 28 and the second positioning member 30 is beneficial to ensure the quality of the multi-section battery cell stack formation.

Further, the first positioning member 28 is configured to apply a greater positioning force to the cell relative to the second positioning member 30. Therefore, during operation of the first positioning member 28 and the second positioning member 30, when the second positioning member 30 pushes the cell toward the first positioning member 28 to adjust the position of the cell, the first positioning member 28 does not move (e.g., move back) due to the relatively small positioning force provided by the second positioning member 30 because of the larger positioning force that the first positioning member 28 can provide. This can ensure the reliability of battery core location effectively, avoids the battery core in the locating process, because the circumstances that first locating component 28 atress drunkenness (if retreat and slide) appears.

In an embodiment, the forming mechanism may include a second drive member 34, and the second drive member 34 may be coupled to the second positioning member 30, the second drive member 34 being configured to drive the second positioning member 30 adjacent to the first positioning member 28. In this way, the second drive member 34 can be used to reduce the distance between the second positioning member 30 and the first positioning member 28 to position the battery cell. In this example, the second drive member 34 may also be used to drive the second positioning member 30 away from the first positioning member 28. In this way, driving the second positioning member 30 to reciprocate in the direction in which the first and second positioning members 28, 30 oppose each other can be achieved by the second drive member 34 to position the battery cell.

In an example, the molding mechanism may further include a first drive member 32, and the first drive member 32 may be coupled with the first positioning member 28. The first drive member 32 is used to drive the first positioning member 28 towards the second positioning member 30. In this way, the first drive member 32 can also be used to reduce the spacing between the second positioning member 30 and the first positioning member 28 to position the cell. In this example, the first drive member 32 may also be used to drive the first positioning member 28 away from the second positioning member 30. In this way, driving the first positioning member 28 to reciprocate in the direction in which the first positioning member 28 and the second positioning member 30 oppose each other can be achieved by the first driving member 32 to position the battery cell.

In the present example, the application of a greater positioning force by the first positioning member 28 on the cell is achieved with the first drive member 32 being configured with a greater driving force relative to the second drive member 34.

Furthermore, in the present example, since both the first positioning member 28 and the second positioning member 30 can be driven, it is more advantageous to enable the molding mechanism to adapt to different sizes of cells.

In an embodiment, both the first drive member 32 and the second drive member 34 may comprise a pneumatic cylinder or an electric cylinder. The cylinder or the electric cylinder included in the first driving member 32 may have a larger diameter than the cylinder or the electric cylinder included in the second driving member 34, so as to realize a larger driving force of the cylinder or the electric cylinder included in the first driving member 32.

In another example (not shown in the figures), the position of the first positioning member is fixed, that is, the first positioning member may be fixed relative to the reference frame of the ground, for example, a driving device for driving the first positioning member is not provided, and the first positioning member is directly mounted on a frame which is fixed in position in the forming mechanism. Thus, the battery core is positioned by matching with the second positioning component driven by the second driving component. Since the first positioning member is fixed, the first positioning member can provide a greater positioning force relative to the second positioning member. And since the first positioning member is fixed, it provides a more reliable positioning of the cell.

In the example given in fig. 1, the first and second positioning members 28, 30 may each comprise a plate for positioning the cells.

In an embodiment, the molding mechanism further includes a frame 62, and both the first drive member 32 and the second drive member 34 may be disposed to the frame 62. As an example, the first drive member 32 and the second drive member 34 may both be arranged in the same manner. Here, taking the first driving member 32 as an example, the forming mechanism may further include a bracket 36 connected to the first driving member 32, the bracket 36 may be formed by welding a plurality of plates, and the bracket 36 formed by welding has better integrity and rigidity, which is beneficial to improve the positioning accuracy when the first driving member 32 performs the positioning operation. The lower end of the bracket 36 may be detachably mounted to the top surface of the frame 62, for example, by bolting, snapping, and the upper end of the bracket 36 may also be detachably mounted to the first drive, for example, by bolting, snapping, and the likeThe components 32 are connected _。 In this way, replacement of the support 36 and replacement of the first drive member 32 is facilitated, thereby adapting the positioning of different sized cells.

In addition, the upper end and the lower end of the bracket 36 are used as the mounting positions of the bracket 36, so that the height of the bracket 36 is allowed to be used as the size index for adapting to the battery cells with different height sizes, and the requirement of the bracket 36 in adapting to the size of the battery cell is favorably reduced. Specifically, in one example, the height of the bracket 36 may be configured to be adjustable. In yet another example, the number of the racks 36 is plural, and the height of the plurality of racks 36 is different, so that different cell sizes can be achieved by selecting different racks 36.

When the first driving member 32 has an air cylinder, the upper end of the bracket 36 can be fixed to the air cylinder of the first driving member 32, and the fixing can be performed by bolt screwing, snap-fit connection, etc. Similarly, the second driving member 34 can be disposed as such, and will not be described herein.

In an embodiment, the molding mechanism includes a third positioning member 10, a fourth positioning member 18, and a force application assembly. The third positioning member 10 and the fourth positioning member 18 are disposed opposite to each other. In one example, a force application assembly is connected to the third positioning member 10 for applying a force to the third positioning member 10 to bring the third positioning member 10 closer to the fourth positioning member 18. As such, the spacing between the third positioning member 10 and the fourth positioning member 18 can be reduced by the force application assembly to apply pressure to the cell. Wherein, the third positioning member 10 and the fourth positioning member 18 are sequentially arranged in the direction in which the plurality of battery cells are stacked.

Further, in this example, the biasing assembly may also be used to bias the third positioning member 10, also to move the third positioning member 10 away from the fourth positioning member 18. In this way, the third positioning member 10 is able to move reciprocally in the direction in which the third positioning member 10 and the fourth positioning member 18 oppose each other, thereby facilitating the third positioning member 10 to exert a force on the cell, and facilitating the third positioning member 10 to release the force from the cell, which will be explained in the following description.

In this example, both the side of the third positioning member 10 facing the fourth positioning member 18 and the side of the fourth positioning member 18 facing the third positioning member 10 are used to position the end plate. In this way, according to the molding mechanism provided in the embodiment of the present application, two end plates, for example, the front end plate and the rear end plate of a multi-segment battery cell, can be positioned at the third positioning member 10 and the fourth positioning member 18, respectively. When the multiple sections of battery cells are placed between the third positioning member 10 and the fourth positioning member 18, a force is applied to the third positioning member 10 by the force application assembly, so that the third positioning member 10 approaches the fourth positioning member 18, thereby pre-pressing the multiple sections of battery cells in the process. And all laminate front end plate and rear end plate in multisection electric core to make piling up the in-process of forming the module with the electric core, the end plate is positioned, for prior art, solved among the prior art manual operation, during frock is supplementary piles up electric core, the problem that shaping efficiency and shaping quality are low that the end plate location difficulty caused.

In an embodiment, the third positioning member 10 and the fourth positioning member 18 may be oppositely disposed along a horizontal direction in fig. 4. Specifically, the horizontal direction may be substantially the front-back direction F1 when the plurality of cell segments are formed, and the left-right direction F2 perpendicular to the front-back direction F1 is mentioned above.

In an embodiment, the forming mechanism may further include a transfer member 38 and a third driving member 40, wherein the third positioning member 10 and the fourth positioning member 18 may be disposed on the transfer member 38 (the specific arrangement will be described later), the transfer member 38 may be connected to the third driving member 40, and the third driving member 40 may be configured to drive the transfer member 38 to move between the emptying station and the material taking station. Therefore, the third positioning member 10 and the fourth positioning member 18 can move together with the transfer member 38, and the distance between the third positioning member 10 and the fourth positioning member 18 can be reduced in the moving process of the transfer member 38, so that the forming mechanism can move from the discharging station for performing prepressing to the material taking station serving as a manual operation station in the process of prepressing the battery cell, and the transfer time of the battery cell from the discharging station to the material taking station is fully utilized, and the efficiency of prepressing the battery cell is improved.

In an embodiment, the transfer member 38 may be a transfer platform, and the third driving member 40 may be an electric slide table. Wherein, electronic slip table can set up in the top surface of frame 62, and electronic slip table can drive and move the platform of carrying and move between the blowing station mentioned earlier and the material station of getting. As an example, the electric slide table may drive the transfer platform to move from the material placing station to the material taking station along the above-mentioned front-back direction F1, a slide block may be disposed below the transfer platform, and the upper end surface of the frame 62 may be provided with the module slide rail 42 that cooperates with the slide block.

In addition, a guide block 44 is arranged on the side of the rack 62 where the emptying station is located, and the guide block 44 is used for guiding the transfer platform when the transfer platform returns to the emptying station.

It should be further noted that the material discharge station may be a station where multiple battery cells are fed, multiple battery cells are positioned (that is, positioned by the first positioning member 28 and the second positioning member 30), and multiple battery cells start to be pre-pressed, and the material discharge station may be a manual operation station, which will be described in detail in the following description.

In an embodiment, the forming mechanism may further include a positioning guide component disposed on the transfer platform, and the positioning guide component is connected to the guide block 44 after the transfer platform returns to the placing station, so that the guide block 44 can limit the position of the positioning guide component, and further limit the position of the transfer platform fixed to the positioning guide component, and ensure that the position of the transfer platform is at the placing station. Specifically, the upper end surface of the guide block may be provided with a hole portion, for example, and the positioning guide unit may include an air cylinder provided on the upper end surface of the transfer platform and a positioning pin connected to a piston rod of the air cylinder. In some examples, the number of positioning guide assemblies may be the same as the number of guide blocks, and may correspond to one another.

In a state where the positioning guide unit is not engaged with the guide block 44, both the piston rod and the positioning pin of the cylinder of the positioning guide unit may be incorporated in the transfer platform. When the transfer platform returns to the emptying station, the piston rod of the cylinder of the positioning guide assembly extends, so that the positioning pin extends out of the lower part of the transfer platform and is inserted into the hole part of the upper end face of the guide block 44, and the transfer platform is ensured to be positioned at the emptying station. Therefore, the situation that the position of the battery cell after being loaded is deviated due to the fact that the transfer platform does not completely return to the discharging station can be avoided, and the positioning and prepressing quality of the battery cell are affected.

In one example, the number of the guide blocks 44 may be two, two guide blocks 44 may be disposed at intervals along the left-right direction F2, and each guide block 44 corresponds to a cylinder and a positioning pin provided with a positioning guide assembly.

In an embodiment, the force application component may be disposed on the transfer member 38, such as an upper end surface of the transfer member 38. The electric cylinder 24 is exemplified as a biasing member, that is, the electric cylinder 24 is provided on the upper end surface of the transfer member 38, and the biasing member is movable in synchronization with the transfer member 38. In this way, the feeding station and the removal station with a longer distance (i.e. the distance between the feeding station and the removal station) described below can be adapted by means of a relatively short stroke of the push rod 26 of the electric cylinder 24, so that cost savings are achieved.

In some examples, which are not shown, the force application component is still exemplified as an electric cylinder, and the electric cylinder may be disposed on the frame, that is, the electric cylinder does not move along with the transfer member. In this case, the rod of the electric cylinder is continuously extended in accordance with the movement of the transfer member. The arrangement is suitable for occasions with shorter intervals between the material placing stations and the material taking stations, is favorable for reducing the size required by the transfer component, and is also favorable for the disassembly, assembly and maintenance of the electric cylinder.

It should be noted that the force application component may also be a driving mechanism such as an air cylinder, a ball screw, a linear motor, etc. instead of an electric cylinder, and the application is not limited thereto.

As shown in fig. 1, the forming mechanism may further include a control mechanism and a sensing assembly disposed outside the material taking station, the sensing assembly may be configured to sense a predetermined area outside the material taking station in an operating state of the sensing assembly, the sensing assembly may be in communication with the control mechanism, and in the operating state of the sensing assembly, an object enters the predetermined area, and the control mechanism controls the sensing assembly to alarm.

In the embodiment, the predetermined regions are disposed on both sides of the material taking station, and the direction defined by the both sides is perpendicular to the direction in which the transfer member 38 moves from the discharge station to the material taking station. At this time, the sensing assembly may include the gratings 52, for example, four gratings 52, and the four gratings 52 may be disposed on the frame 62, and specifically, the four gratings 52 may be distributed in a rectangular shape. Of the four gratings 52, two gratings 52 located on the same side in the left-right direction F2 cooperate with each other to sense an area therebetween. Here, the region between the two gratings 52 on the same side is the predetermined region described above. The sensing assembly may be activated when the transfer member 38 moves from the dispensing station to the dispensing station, thereby ensuring that the body of the operator, such as a hand or arm, does not enter the transfer member 38 and the path that the rest of the components disposed thereon should have traveled via the sensing region (i.e., the predetermined region) of the grating 52, thereby preventing injury to the operator. In other words, once the operator is sensed by the optical grating 52 during the movement of the transfer member 38 from the feeding station to the discharging station, the control mechanism can timely control the optical grating 52 to alarm and remind the operator.

In another example, the sensing assembly may be configured to sense an area at which the reclaiming station is located in an operational state of the sensing assembly. At this moment, sensing subassembly still can include the grating, cooperates each other through the grating that sets up in pairs for the induction zone of the grating that sets up in pairs passes through the material taking station, and this makes the grating sensing under operating condition be the area that the material taking station was located. Under the working state of the grating, if the body of an operator, such as a hand and an arm, enters the area where the material taking station is located, the grating controls the grating to alarm by the control mechanism to remind the operator after sensing the body of the operator.

Further, in an embodiment, the molding mechanism may include a control mechanism, the control mechanism may be in communication with the third driving member 40, and the control mechanism may be further configured to control the force application assembly to perform pre-pressing on the battery cell disposed between the third positioning member 10 and the fourth positioning member 18 during the movement of the transfer member 38 from the discharge station to the take-out station. That is to say, the pre-pressing process is completed in the process of transferring the plurality of sections of battery cells by the transfer member 38, and once the transfer member 38 reaches the material taking station, the next operation can be directly performed on the pre-pressed plurality of sections of battery cells, the front end plate and the rear end plate without waiting, and the pre-pressing process is not required to be completed at the material placing station and then the battery cells are transferred to the material taking station in the prior art, so that the transfer time is fully utilized, the continuity of the process is improved, and the molding efficiency of the battery cell module 64 is effectively improved.

In an embodiment, the forming mechanism may include a placing member 46, the placing member 46 may be used for placing the battery core, the placing member is disposed between the third positioning member 10 and the fourth positioning member 18, and the placing member 46 is configured to be movable between the third positioning member 10 and the fourth positioning member 18 along a direction in which the third positioning member 10 and the fourth positioning member 18 are opposite to each other, i.e., a front-back direction F1. This allows the multi-segment battery cell to be positioned by the first positioning member 28 and the second positioning member 30, and then the electric cylinder 24 can push the multi-segment battery cell together with the placing member 46 to move toward the fourth positioning member 18, so that the pre-compression is started when the multi-segment battery cell abuts against the fourth positioning member 18.

The placing member 46 may be a placing platform, and the placing member 46 may be movably connected with the transferring member 38, for example, slidably connected, that is, the placing platform is slidably disposed on the upper end surface of the transferring platform. For example, the upper end surface of the transfer platform is provided with a slide rail extending along the front-back direction F1, and the lower end surface of the placing platform is provided with a slide block for matching with the slide rail. The placing member 46 may be disposed between the third positioning member 10 and the fourth positioning member 18 for placing a plurality of battery cells. Therefore, in essence, the placing member 46 is also located between the first positioning member 28 and the second positioning member 30 described above when placing a plurality of battery cells, that is, when loading the battery cells.

This slidable placement platform is particularly advantageous in that friction between the cell and the placement platform causes the placement platform to move with the cell as the cell is pushed by the cylinder 24 of the force application assembly described below. The battery cell is prevented from being pushed on the fixing platform and having a relatively long friction stroke with the surface of the fixing platform, the position deviation of the positioned multiple battery cells is avoided, the forming quality of the multiple battery cells is favorably ensured, and the processing requirement of the surface of the placing platform, which is in contact with the battery cells, can be reduced.

Further, in an embodiment, the forming mechanism further comprises a first sensing member 48. Wherein the first sensing member 48 may be in communicative connection with the control mechanism. As an example, the first sensing member 48 may be disposed on the placing member 46, for example, embedded on the upper end surface of the placing member 46, the first sensing member 48 may be in communication with the control mechanism, and the first sensing member 48 is used for sensing the battery cell placed on the placing member 46. That is, the first sensing member 48 can sense the cell after the cell is placed on the placing member 46, so as to transmit the sensing signal to the control mechanism, thereby providing a precondition for the control mechanism to control the force application assembly.

After the sensing signal of the first sensing member 48 sensing the cell is transmitted to the control mechanism, the control mechanism will control the force application assembly to apply force to the third positioning member 10, so as to perform the pre-pressing operation on the cell. The advantage of this arrangement is that it is avoided that the pre-pressing operation is performed without the cells being loaded. Because the pre-pressing operation is performed without the cell being loaded, there is no correct pre-pressing object. Thus, the first sensing component 48 is utilized to effectively avoid misoperation, and the yield of cell prepressing is improved.

In an embodiment, the forming mechanism may further include a reset member 50, and the reset member 50 may be used to drive the electrical core placed on the placement member 46 away from the fourth positioning member 18.

As an example, the reset member 50 can be used to apply a force to the cell or placement member 46 to drive the cell away from the fourth positioning member 18. Specifically, when the placement member 46 is provided, the reset member 50 may apply a force to the cell or placement member 46 to drive the placement member 46 and the cell placed on the placement member 46 away from the fourth positioning member 18; and when the placement member 46 is not present, the reset member 50 can apply a force to the cell to drive the cell away from the fourth positioning member 18. Like this, after the preliminary pressing, the force application assembly can drive the third positioning member 10 to keep away from the fourth positioning member 18, and the placing member 46 makes the electric core and the fourth positioning member 18 separate, so as to carry out the electric core that the preliminary pressing was accomplished so as to further improve the work efficiency of the forming mechanism.

In an embodiment, a reducing member 50 may also be provided to the placing member 46 to drive the core placed on the placing member 46 away from the fourth positioning member 18. For example: the reset member 50 is used to apply a force to one of the third positioning member 10 and the fourth positioning member 18 to move the placement member 46 toward the third positioning member 10. As an example, in an embodiment, the reset member 50 may be a pop-up cylinder, which may be disposed at a lower end surface of the placement member 46. After the pre-pressing is finished, the piston rod of the pop-up cylinder extends towards the second seat 22, so that the battery cell is separated from the fourth positioning member 18, and the battery cell after the pre-pressing is finished is conveniently carried out.

Furthermore, in some examples not shown, the return member may be served by an energy storage member connecting the placement member with the first seat, where the energy storage member may be, for example, a tension spring.

Further, in some examples not shown, the returning member may also be provided to the upper end face of the transfer member, for example, the returning member may still be a cylinder. As an example, the cylinder may be a rod cylinder which may push or pull the placement member with the piston rod. In addition, the cylinder can also be a rodless cylinder, the cylinder body of the cylinder can be connected with the placing component, and the moving of the cylinder body drives the placing component to move.

As another example, the reset member may be a rod cylinder, and the reset member may be disposed on one side of the placing member in the front-rear direction, for example, the reset member may be disposed on the side of the fourth positioning member, so that the piston rod of the reset member may directly push the battery cell so that the battery cell is away from the fourth positioning member. On this basis, the piston rod can push the battery cell and simultaneously push the battery cell together with the placing component, so that the battery cell can be prevented from sliding relative to the placing component to cause battery cell abrasion.

As another example, the reset member may be a rod cylinder, for example, the reset member may be disposed at a side of the third positioning member, such that a piston rod of the reset member may be connected with the placing member, for example, to pull the placing member such that the placing member and the battery cell placed on the placing member are away from the fourth positioning member.

In an embodiment, the molding mechanism may further include a first seat 14 and a second seat 22. Here, the first seat 14 and the second seat 22 may be provided on the upper end surface of the transfer member 38 so as to face each other along the front-rear direction F1, and here, both the first seat 14 and the second seat 22 may be formed by welding plate members. The fourth positioning member 18 may be disposed on the second seat 22, for example, a plate included in the fourth positioning member 18 may be disposed on a side of the second seat 22 facing the first seat 14. Thus, the first seat 14 and the second seat 22 provide a carrier for the third positioning member 10 and the fourth positioning member 18, respectively, which facilitates the third positioning member 10 and the fourth positioning member 18 to be stably disposed on the upper end surface of the transfer member 38.

As an example, the first seat 14 and the second seat 22 may have the same structure. Taking the first seat 14 as an example, the first seat 14 may include two plates disposed perpendicular to each other, wherein one of the two plates disposed perpendicular to each other is used to be disposed horizontally on the transfer platform, and the other of the two plates disposed perpendicular to each other is used to be disposed vertically. Further, the first seat 14 may further include a right-angle trapezoidal reinforcing plate, and two right-angle sides of the right-angle trapezoidal reinforcing plate are respectively used for being connected with two plates vertically arranged to each other, so as to play a role in reinforcing the two plates vertically arranged to each other. This is advantageous in that the third positioning member 10 and the fourth positioning member 18 can be stably provided on the upper end surface of the transfer member 38.

In some examples, not shown, a reset member may also be provided to the first seat. Here, the first seat is located on the side of the third positioning member, so the reset member may be, for example, a rod cylinder, and a piston rod of the rod cylinder may be connected to the placing member, so as to pull the placing member and the battery cell placed on the placing member away from the fourth positioning member. In another example, the reset member may be further disposed on the second seat, and the second seat is located at a side of the fourth positioning member, so that the reset member may also be, for example, a rod cylinder, and a piston rod of the rod cylinder may directly push the battery core, so that the battery core is away from the fourth positioning member. On the basis, the piston rod of the rod cylinder can be pushed together with the placing component, so that the phenomenon that the battery cell slides relative to the placing component to cause battery cell abrasion is avoided.

Further, the connecting member of the urging assembly, i.e., the rod 26 of the electric cylinder 24, described below may extend through the first seat 14 to be connected to the above-mentioned intermediate plate, that is, the first seat 14 supports the rod 26 of the electric cylinder 24, the intermediate plate, and the third positioning member 10. On this basis, preferably, a linear bearing (not shown in the figure) may be disposed between the push rod 26 of the electric cylinder 24 and the first seat 14, and the linear bearing is favorable for ensuring that the push rod 26 performs a high-precision linear motion, so that the motion of the push rod 26 is more stable, and the stability of the third positioning member for applying force to the battery cell is favorably improved.

Further, in an embodiment, the molding mechanism may also include a pressure sensor 16. Wherein the control mechanism can be in communication with the force application assembly, and the pressure sensor 16 can be disposed on at least one of the third positioning member 10 and the fourth positioning member 18. In an embodiment, the pressure sensor 16 may be configured to detect a pressure when the multiple sections of battery cells are pre-pressurized, and may be in communication with the control mechanism, and transmit a detected pressure signal to the control mechanism. Thus, the control mechanism may be configured to adjust the force applied by the apply assembly to the third positioning member 10 based on the pressure signal transmitted by the pressure sensor 16 to the control mechanism. So just realized the closed loop control to the power of pre-compaction, be favorable to quantizing pressure, improved the shaping quality of electric core module 64. Further, as an example, in an embodiment, the control mechanism may be a computer.

In an embodiment, the pressure may be preset according to the number of cells or the process requirement of cell formation. This predetermined pressure may be set by calibration before pre-pressing the cell, for example by providing a test piece to which the third positioning member 10 applies pressure. The test piece is forced by the third positioning member 10, and the pressure exerted by the third positioning member 10 is calibrated to a preset pressure according to the feedback of the pressure sensor 16. From this, when carrying out the pre-compaction to the electric core, can make the pressure of exerting keep the aforementioned pressure of predetermineeing through pressure sensor 16 to play the effect of exerting force more accurately to the electric core, this is favorable to improving the shaping quality of electric core. As an example, the preset pressure may be a point value or a pressure range.

As shown in fig. 1, the force application assembly may include a connection member connected with the third positioning member 10, as an example. Specifically, the force application assembly may include an electric cylinder 24, and correspondingly, the connecting member may be a push rod 26 of the electric cylinder 24. In an embodiment, the push rod 26 of the electric cylinder 24 may be connected with a plate comprised by the third positioning member 10.

When the pressure sensor 16 is provided, an intermediate plate is provided between the plate included in the third positioning member 10 and the push rod 26 of the electric cylinder 24, the pressure sensor 16 is provided between the intermediate plate and the plate included in the third positioning member 10, and the electric push rod 26 is connected to the intermediate plate.

Furthermore, in contrast to the previous examples, in the example not shown, the force application assembly may comprise a ball screw, i.e. connected with the third positioning member by means of a nut moving in the ball screw, for the purpose of applying the pre-pressure. In this example, the connection manner of the nut and the third positioning member and the arrangement manner of the pressure sensor may be the same as those in the above example, and are not described again here.

In an embodiment, the third positioning member 10 and the fourth positioning member 18 may position the end plate in the same manner. Here, taking the fourth positioning member 18 as an example, the fourth positioning member 18 may include a plate member and a suction portion provided to the plate member. As shown in fig. 6, the side of the plate member facing the third positioning member 10 may be provided with the aforementioned attraction portion, and the attraction portion is used to attract the end plate, thereby positioning the end plate. In the embodiment, as a preferable example, the attraction portion may be a vacuum chuck 20 that attracts the end plate by air pressure or a magnet that attracts the end plate by magnetic force, thereby reducing the complexity of the structure for positioning the end plate to some extent. And simultaneously, the positioning of the end plate can be completed quickly. The attraction portion of the third positioning member 10 is shown in fig. 3 and will not be described herein.

In an embodiment, the forming mechanism may comprise a second inductive member 12. The third positioning member 10 and the fourth positioning member 18 are each provided with a second inductive member 12. For example, two second sensing members 12 are respectively embedded on a side of a plate included in the third positioning member 10 facing the fourth positioning member 18 and a side of a plate included in the fourth positioning member 18 facing the third positioning member 10, the second sensing members 12 can be used for sensing an end plate, and the second sensing members 12 are in communication connection with a control mechanism. That is, when the end plate is mounted on the third positioning member 10 and the fourth positioning member 18, the second sensing member 12 can sense the end plate, so as to transmit the sensing signal to the control mechanism, thereby providing a precondition for the control mechanism to control the force application assembly.

After the signal that the second sensing member 12 senses the end plate is transmitted to the control mechanism, the control mechanism will control the force application assembly to apply force to the third positioning member 10, so as to perform pre-pressing operation on the battery cell. This has the advantage that it is avoided that the pre-pressing operation is performed without the end plates being loaded. Because the pre-pressing operation is executed under the condition that the end plate is not loaded, the battery cell can be directly stressed and possibly damaged, and the aim of mounting the end plate on the battery cell can not be achieved. In this embodiment, the second sensing component 12 is arranged to effectively avoid the aforementioned misoperation, which is beneficial to improving the yield of cell prepressing.

As an example, the first sensing member 48 and the second sensing member 12 may be used together, that is, the pre-pressing operation can be prevented from being performed when the cell is not loaded and/or the end plate is not loaded, so that the above-mentioned misoperation can be more effectively avoided, and the yield of cell pre-pressing can be more favorably improved.

Further, as an example, the first sensing member 48 and the second sensing member 12 may both be photosensors.

In an embodiment, the molding mechanism may further include a button cartridge 56, and the button cartridge 56 may be provided with an activation button 58, which may be used to activate the grating. Further, in an embodiment, two activation buttons 58 of the light barrier 52 are provided on each set of button boxes 56, such that the light barrier 52 can be activated and deactivated with both hands using the two activation buttons 58.

Further, the molding mechanism may include two sets of button boxes 56, which may be disposed on two sides of the frame 62 where the two sets of gratings 52 are located (the gratings 52 that are located on the same side and engaged with each other are a set of gratings 52). That is, the two sets of button boxes 56 may be disposed on two sides of the material taking station, and the direction determined by the two sides is perpendicular to the moving direction of the transfer component from the material placing station to the material taking station, so as to control the two sets of rasters 52 respectively. Thus, when the operator is positioned on one of the two sides, the group of rasters 52 on the corresponding side can be opened and closed by the corresponding button box. On one hand, the grating does not need to be completely opened, which is beneficial to energy saving, and on the other hand, when the operator opens the grating on one side, the operator presses the button box to start the grating by two hands, and the hands do not extend into the sensing area (namely the preset area) of the grating on the side of the operator, so that the safety risk is reduced.

In addition, each group of button boxes 56 is further provided with an emergency stop button 60, and the emergency stop buttons 60 can be in communication connection with a control mechanism to be used for stopping the forming mechanism, that is, once the grating senses an object entering a grating sensing area, after an alarm is triggered, an operator can timely utilize the emergency stop buttons 60 to stop the forming mechanism, so that safety accidents are avoided.

In addition, can set up two yard guns 54 of sweeping at the interval on left and right sides direction F2 on the frame 62, sweep a yard gun 54 and be used for scanning the two-dimensional code on the post-forming electric core module 64 to upload the information with electric core module 64.

And repeating the steps until all the single-row cells are placed.

Further, the push rod 26 of the electric cylinder 24 extends to pre-press the battery cell module 64, and then the left and right air cylinders retract to retract the first positioning member 28 and the second positioning member 30.

It should be noted that when the transfer member 38 is not stopped at the material taking station, the start button 58 is manually pressed by both hands, the optical grating 52 is in a start state, and if an object is sensed to enter the movement track of the battery cell module 64, the optical grating 52 gives an alarm. After the battery cell module 64 is in place, the grating 52 is manually stopped.

After the battery cell module 64 is in place, and after the left and right end plates are manually locked by an operator, the battery cell module 64 data is uploaded by using the code scanning gun 54, and the pop-up cylinder below the placing member 46 extends out to pop the placing member 46 from the side where the fourth positioning member 18 is located, and returns to the side where the third positioning member 10 is located. At this time, the front end plate and the rear end plate are assembled in the pre-pressing process, the left side end plate and the right side end plate are also locked by manpower, and the battery cell module 64 can be taken down by utilizing a crane. After the battery cell module 64 is taken down. An operator manually positions a new front end plate and a new rear end plate on the third positioning component 10 and the fourth positioning component 18 respectively to complete the feeding of the end plates, then the electric sliding table drives the transfer component 38 to return to the discharging station, and the processes are repeated.
