[0042] The present invention provides a tidying device, which comprises: a battery cell tidying device 1, a battery cell conveying device 2, a tool tidying device 3 and a tool conveying device 4; wherein,

[0043] The cell conveying device 2 is used to convey the cell 10, and the cell aligning device 1 is used to align the position of the cell 10. When the cell conveying device 2 conveys the cell 10 to the first aligning position, the cell aligning device 1 aligns the cell 10 located at the first aligning position;

[0044] The tool conveying device 4 is used to convey the compacting tool 20, and the tool regularizing device 3 is used to regularize the position of the compacting tool 20. When the tool conveying device 4 conveys the compacting tool 20 to the second regularizing position, the tool regularizing device 3 regularizes the compacting tool 20 located at the second regularizing position;

[0045] The first regularization position and the second regularization position are arranged so that there is a predetermined relative position between the battery cell 10 regularized at the first regularization position and the pressing tool 20 regularized at the second regularization position, so that the handling device can simultaneously grasp the battery cell and the pressing tool with the predetermined relative position.

[0046] When producing battery strings, in order to improve the preparation efficiency of battery strings, they are usually stacked and welded continuously to form a longer string, and then the longer battery string is divided into multiple independent battery strings. During the stacking process of the battery strings, the pressing tool is pressed on the front section of each group of welding strips, and the battery cells are pressed on the rear section of the same group of welding strips; wherein, in order to make two adjacent battery strings continuous, the welding strips between two adjacent battery strings are relatively long, and the welding strips are used as the last group of welding strips of the previous battery string and the first group of welding strips of the next battery string. The relative distance between the battery cells placed on the welding strips between the two battery strings and the pressing tool is greater than the relative distance between the battery cells and the pressing tool on the welding strips between a battery string. Therefore, when the handling device carries the battery cells and the pressing tool at the position between two adjacent battery strings, it is necessary to adjust the relative distance between the first regular position and the second regular position, which can be achieved by adjusting the position of the regular mechanism on the tool regular device 3, which will be further described in the tool regular device 3 below.

[0047] In the technical solution provided by the present invention, by respectively regularizing the positions of the battery cells and the pressing tooling, the battery cells to be transported and the pressing tooling can be placed in a certain relative position, so that the transport device can simultaneously grab the battery cells and the pressing tooling with relative positions without adjustment, which is beneficial to improving the transport efficiency of the battery cells and the pressing tooling, and thereby improving the production efficiency of the battery string.

[0048] In a preferred embodiment, the specific structure of the battery sheet regularization device 1 is as follows: Figure 2 As shown, the battery sheet tidying device 1 includes a frame 11, two movable frames 12 arranged on the frame 11, and a first driving mechanism 13 for driving the two movable frames 12 to approach each other and move away from each other.

[0049] In order to ensure that the movable rack 12 can move stably relative to the frame 11 , a guide rail can be provided between each movable rack 12 and the frame 11 , and the movable rack 12 moves along the guide rail.

[0050] Among them, each of the mobile racks 12 is respectively provided with a battery cell tidying component. When the battery cell conveying device 2 conveys the battery cells 10 to be tidy to the first tidying position between the two mobile racks 12, the battery cell tidying components on the two mobile racks 12 push the battery cells 10 from both sides for tidying under the drive of the first driving mechanism.

[0051] Preferably, the tidying component includes a rotatable tidying wheel 123 disposed on the mobile frame 12, and the tidying wheel 123 is configured so that the outer peripheral surface contacts the battery cell to be tidyed. By the outer peripheral surface of the rotatable tidying wheel 123 contacting the battery cell, the pushing is flexible, and friction between the battery cell and the battery cell can be avoided when the battery cell is pushed.

[0052] Specifically, Figure 2 As shown, each of the mobile frames 12 includes a mobile body 121 and a mounting portion 122 connected to the mobile body 121, the mounting portion 122 is a long strip structure extending in a direction perpendicular to the moving direction, and at least two regularizing wheels 123 are arranged on the mounting portion 122 at intervals along the length direction.

[0053] Preferably, the mounting portion 122 is configured to be able to adjust the connection position with the mobile body 121 in the length direction, so that when the frame 11 is fixed, the position of the tidying wheel 123 can be adjusted in a direction perpendicular to the moving direction.

[0054] Preferably, the mounting portion 122 is configured to be able to adjust the connection position with the mobile body 121 in the moving direction. Adjusting the connection position of the mounting portion 122 in the moving direction can make the regularizing wheel 123 on the mounting portion 122 suitable for regularizing battery cells of different widths.

[0055] In order to facilitate the adjustment of the connection position of the mounting portion 122, a connection block 124 is connected between the mobile body 121 and the mounting portion 122, and the connection block 124 includes a first connection portion 1241 connected to the mobile body 121 and a second connection portion 1242 connected to the mounting portion 122; wherein one of the first connection portion 1241 and the mobile body 121 is provided with a first elongated hole extending along the moving direction, and the first connection portion 1241 is configured to be able to adjust the mounting position with the mobile body 121 along the first elongated hole. One of the second connection portion 1242 and the mounting portion 122 is provided with a second elongated hole extending along the length direction of the mounting portion 122, and the second connection portion 1242 is configured to be able to adjust the mounting position with the mounting portion 122 along the second elongated hole.

[0056] In this embodiment, the first driving mechanism 13 for driving the two moving frames 12 to move includes a motor 131, a driving wheel 132 and a driven wheel 133 driven by the motor 131, and a conveyor belt 134 wound around the driving wheel 132 and the driven wheel 133;

[0057] The two moving racks 12 are respectively connected to the two sides of the conveyor belt 134 running in the opposite direction, so that when the conveyor belt 134 runs, the two moving racks 12 approach each other or move away from each other.

[0058] In order to connect the mobile frame 12 with the conveyor belt 134, the conveyor belt 134 is set as a toothed belt, and each mobile frame 12 is connected with a toothed block 125, which engages with the teeth on the conveyor belt 134 so that the conveyor belt 134 drives the mobile frame 12 to move through the toothed block.

[0059] It is understood by those skilled in the art that the first driving mechanism for driving the two mobile racks 12 to move is not limited to the mode of being driven by a conveyor belt. For example, each mobile rack 12 may also be provided with an independent driving mechanism, and the mobile racks 12 may be driven by their own independent driving mechanisms to move toward or away from each other. The first driving mechanism may be a linear driving mechanism such as a cylinder or a ball screw. In addition, the specific structures of the frame 11 and the mobile rack 12 may also be adaptively changed.

[0060] Figure 3 The figure shows the state of cooperation between the cell conveying device 2 and the cell tidying device 1 as described above. The cell conveying belt of the cell conveying device 2 extends into between the two tidying components of the cell tidying device 1. When the cell conveying device 2 conveys the cell 10 between the two tidying components (the tidying wheels 123 on the mounting portion 122), the two tidying components push the cell 10 from opposite sides of the cell 10 to achieve tidying of the cell.

[0061] In one embodiment, the specific structure of the tooling regularization device 3 is as follows: Figure 4 As shown, the tool aligning device 3 includes a mounting base 31, an aligning mechanism for aligning the pressing tool, and a second driving mechanism 39; the aligning mechanism is movably mounted on the mounting base 31, and the second driving mechanism 39 is configured to drive the aligning mechanism to move relative to the mounting base 31. By driving the aligning mechanism to move by the second driving mechanism 39, the predetermined position to be reached by the pressing tool 20 through aligning can be adjusted, so that the aligning pressing tool 20 and the aligning battery cell 10 have a predetermined relative position.

[0062] In order to adjust the predetermined position to be regularized by the pressing tool according to the position of the regularized battery cells, the regularization equipment also includes a detection device for detecting the regularized battery cells at the first regularization position. According to the position of the battery cells detected by the detection device, the second driving mechanism 9 drives the regularization mechanism to move to adjust the second regularization position.

[0063] Specifically, the detection device may include a camera arranged above the first regularization position, which obtains the position of the regularized battery cell and sends the position information to the control unit. The control unit controls the second driving mechanism 9 to drive the regularization mechanism to move, so that the regularization mechanism moves to a suitable position to regularize the clamping tooling, thereby adjusting the relative distance between the first regularization position and the second regularization position.

[0064] The tooling tidying device provided in this embodiment is described in detail below.

[0065] like Figure 4 As shown, the arranging mechanism in the tool arranging device includes an arranging frame 32, on which two limit bars 33 are arranged, and a space for accommodating the pressing tool 20 to be arranging is formed between the two limit bars 33, and a stopper 35 is also arranged on the arranging frame 32, and the stopper 35 is located at one end of the two limit bars 33 close to the first arranging position;

[0066] The tooling regularization device further includes a pushing portion 36 close to one of the limiting strips 33 and a third driving mechanism for driving the pushing portion 36 to move toward the other limiting strip 33;

[0067] When the pressing tool 20 to be regulated enters between the two limiting bars 33 from the end of the limiting bar 33 away from the stopper 35 and moves to press against the stopper 35, the third driving mechanism drives the pushing part 36 to press the pressing tool 20 against the other limiting bar 33. In other words, the pressing tool 20 is moved to press against the stopper 35, and the two ends are limited by the pushing part 36 and one of the limiting bars 33, so that the pressing tool 20 can be ensured to be in a predetermined position.

[0068] Preferably, each of the limit strips 33 includes a straight portion 332 and an outward expansion portion 331 arranged at one end of the straight portion 332, the straight portions 332 of the two limit strips 33 are parallel to each other's sides, and the outward expansion portion 331 forms an outward expansion opening at one end of the two limit strips 33 that is away from the stop block 35, and the clamping tool 20 to be regularized enters between the two limit strips 33 from the outward expansion opening and moves to press against the stop block 35.

[0069] When in use, the clamping tool 20 to be regulated can be conveyed by a tool conveying device. During the conveying process, the clamping tool 20 enters between the limit bars 33 from the outwardly expanded opening at one end of the limit bar 33 until it is conveyed to the top of the stop block 35, and then one end of the clamping tool 20 is pushed by the pushing part 36 to push the clamping tool 20 to the straight portion 332 of one of the limit bars 33.

[0070] Preferably, the stopper 35 is arranged such that the installation position on the tidying frame 32 can be adjusted along the length direction of the limiting strip 33, thereby adjusting the predetermined position to which the pressing tool 20 is to be tidyed. Specifically, the adjustment can be made by setting an elongated hole or a plurality of different installation holes.

[0071] In this embodiment, the tidying frame 32 is also provided with a padding component located between the two limit bars 33, and the end of the padding component facing away from the stopper 35 is tilted downward, and when the pressing tool 20 to be tidy moves to enter between the two limit bars 33, it moves from the end of the padding component facing downward to the padding component. Preferably, the padding component includes two padding bars 34 for supporting the opposite ends of the pressing tool 20, and the padding bars 34 are long strip structures whose length direction is consistent with the moving direction of the pressing tool 20 when entering between the two limit bars 33, and the ends of the two padding bars 34 facing away from the stopper 35 are both tilted downward.

[0072] When the clamping tool 20 to be regulated moves to enter between the two limit strips 33, the two ends of the clamping tool 20 respectively move from the inclined downward end of the padding strip 34 to the padding strip 34. The clamping tool 20 is lifted by the padding strip 34 to prevent friction between the clamping tool 20 and the structure below.

[0073] In this embodiment, a stopper 37 for preventing the pressing tool 20 from tilting upward is further provided on the tidying frame 32 . Figure 4 It is shown in the figure that stop components 37 are respectively installed near the two limit bars 33.

[0074] In order to realize automatic arranging of the clamping tool 20, a proximity switch 38 is also provided on the arranging frame 32. When the clamping tool 20 moves from one end of the limit bar 33 to the stop block 35 close to the other end, the proximity switch 38 can detect the clamping tool 20. When the proximity switch 38 detects the clamping tool 20, the third driving mechanism drives the pushing part 36 to press the clamping tool 20, wherein the third driving mechanism can be a cylinder (the third driving component is not shown in the figure).

[0075] In this embodiment, if Figure 4As shown, the tidying frame 32 includes a moving plate 322 and two tidying mounting plates 321 arranged at one end of the moving plate 322, and the two tidying mounting plates 321 are arranged at intervals and extend from one end of the moving plate 322. Two limit bars 33 are respectively arranged corresponding to one tidying mounting plate 321, and two padding bars 34 are also respectively arranged corresponding to one tidying mounting plate 321. In addition, a stopper 35 is arranged at one end of the tidying mounting plate 321 away from the moving plate 322, and one of the stoppers 35 is respectively arranged on each tidying mounting plate 321.

[0076] The second driving mechanism 9 is connected to the moving plate 322 of the tidying frame 32, and drives the tidying mechanism to move relative to the mounting seat 31 by driving the moving plate 322. The second driving mechanism 9 can be a lead screw mechanism driven by a motor, and the moving plate 322 of the tidying frame 32 is connected to a nut that rotates in cooperation with the lead screw. During the rotation of the lead screw, the movement of the nut drives the moving plate 322 to move to adjust the position of the tidying mechanism. The second driving mechanism 9 can also be a driving mechanism such as a cylinder.

[0077] like Figure 5 and Figure 6 As shown, the tooling conveying device 4 includes a tooling conveyor belt 41 for conveying the compacting tooling, the tooling conveyor belt 41 extends into between the two limit bars 33 of the tooling regularization device 3, and the compacting tooling 20 is conveyed by the tooling conveyor belt 41 to enter between the two limit bars 33. The conveyor belt 201 includes two, and the two ends of the compacting tooling 20 to be conveyed are supported on one of the tooling conveyor belts 41 respectively.

[0078] In this embodiment, in order to facilitate the setting of the first regularization position and the second regularization position, the battery cell and the pressing tool are regularized in any predetermined relative position. The battery cell conveyor belt is configured to extend from one end of the tool conveying device 4 to enter between the two tool conveyor belts 41; the first regularization position and the second regularization position are located at the intersection of the battery cell conveyor belt and the tool conveyor belt 41.
