The fixing component secures the battery cell, the bending block is connected to the tilting cylinder, and the bending block is brought into contact with the battery protection board. Then, the tilting cylinder drives the bending block to tilt, causing the bending block to apply force to the battery protection board, thereby achieving the bending of the battery protection board.

Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0021] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0022] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0023] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0024] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings.

[0028] The following will combine Figures 1 to 7 Describe the bending equipment, in Figures 1 to 7 In the diagram, the first direction L1 intersects with the second direction L2, and the third direction L3 intersects with the plane defined by the first direction L1 and the second direction L2. Preferably, the intersection is perpendicular. The bending device will be described below with the first direction L1, the second direction L2 and the third direction L3 being perpendicular to each other as an example.

[0029] The bending device of this application is used to bend the battery protection board 32 in the battery 3. The battery includes a cell 31 and a battery protection board 32. Before bending the battery protection board 32, such as Figure 4 As shown, the battery protection board 32 is connected to the battery cell 31, with a portion of the battery protection board 32 extending out from the battery cell 31. Figures 1 to 7As shown, the bending device includes a carrier 1 and a bending assembly 2. The carrier 1 has a receiving cavity for accommodating the battery cell 31, with the battery protection board 32 exposed outside the cavity. The bending assembly 2 includes a first bending drive and an adsorption member 21. The first bending drive is connected to the adsorption member 21 and can drive the adsorption member 21 to flip, thus adsorbing the battery protection board 32. When the bending device is in use, the carrier 1 fixes the battery cell 31, the adsorption member 21 adsorbs the battery protection board 32, and then the first bending drive drives the adsorption member 21 to flip, thereby bending the battery protection board 32. In this way, the adsorption member 21 adsorbs the battery protection board, ensuring the stability of the relative position between the adsorption member 21 and the battery protection board 32 during the bending process, preventing changes in the force applied by the adsorption member 21 to the battery protection board 32, and reducing the risk of misalignment of the battery protection board 32 after bending.

[0030] Optionally, the first bending drive ( Figures 1 to 7 (Not shown in the image) is a tilting cylinder.

[0031] In embodiments of this application, the bending device further includes a transport drive 41 and a mounting platform 42. The mounting platform 42 is connected to the transport drive 41, and the transport drive 41 can drive the mounting platform 42 to move along a first direction L1 between a first position and a second position. The carrier 1 is mounted on the mounting platform 42. When the transport drive 41 drives the mounting platform 42 to the first position, the battery cell 31 of the battery 3 can be placed in the receiving cavity of the carrier 1. Then, the transport drive 41 drives the mounting platform 42 to move. When the mounting platform 42 moves to the second position, the battery protection board 32 can be bent by the bending assembly 2.

[0032] like Figure 1 and Figure 2 As shown, the mounting platform 42 includes a first mounting plate 421, a second mounting plate 422, and four connecting rods 423. For any one connecting rod 423, one end of the connecting rod 423 is connected to the first mounting plate 421, and the other end of the connecting rod 423 is connected to the second mounting plate 422. The four connecting rods 423 are arranged at intervals. The first mounting plate 421 is used to support the carrier 1, and the second mounting plate 422 is connected to the transport drive component 41.

[0033] Optionally, the transport drive 41 can be a linear module.

[0034] In addition, bending equipment may also include a detection component ( Figures 1 to 7 (Not shown in the image), the detection component is located above the mounting platform 42 and between the first position and the second position. The detection component is used to detect the position of the battery 3.

[0035] Optionally, the detection components may include a CCD camera and a bracket for mounting the CCD camera.

[0036] like Figure 2 As shown, the bending device also includes a first telescopic member 43, a second telescopic member 44, and an abutment member 45. The abutment member 45 is fixed to the mounting plate and can be L-shaped. The abutment member 45 includes a first abutment surface and a second abutment surface. The first abutment surface is perpendicular to the first direction L1, and the second abutment surface is perpendicular to the second direction L2. Both the first telescopic member 43 and the second telescopic member 44 are connected to the mounting plate. The first telescopic member 43 can extend and retract along the first direction L1, and the second telescopic member 44 can extend and retract along the second direction L2. When installing the carrier 1, the carrier 1 is placed on the first mounting plate 421, so that both the first abutment surface and the second abutment surface are in contact with the carrier 1. Then, the first telescopic member 43 and the second telescopic member 44 extend, so that the first abutment surface, the second abutment surface, the first telescopic member 43, and the second telescopic member 44 are all in contact with the carrier 1, thereby fixing the carrier 1. When releasing the carrier 1, the first telescopic member 43 and the second telescopic member 44 retract, and the carrier 1 can be removed.

[0037] Optionally, both the first telescopic member 43 and the second telescopic member 44 are cylinders.

[0038] like Figure 4 As shown, the carrier 1 includes a first carrier 11 and a second carrier 12. The first carrier 11 is flat, and the second carrier 12 is U-shaped. One end of the first carrier 11 is connected to the second carrier 12 via a rotating shaft. The other end of the first carrier 11 has a first mounting hole, and a first magnetic chuck 13 is disposed in the first mounting hole. The second carrier 12 has a second mounting hole, and a second magnetic chuck 14 is disposed in the second mounting hole. The first magnetic chuck 13 and the second magnetic chuck 14 attract each other, causing the end of the first carrier 11 away from the rotating shaft to abut against the second carrier 12. The first carrier 11 and the second carrier 12 form a receiving cavity. The first carrier 11 and the second carrier 12 are opened and closed by the first magnetic chuck 13 and the second magnetic chuck 14, thereby improving the convenience of battery 3 installation.

[0039] Optionally, both the first magnetic attractor 13 and the second magnetic attractor 14 are magnets.

[0040] It should be noted that, in Figures 1 to 5 The first support member 11, which is away from the rotation axis, is spaced apart from the second support member 12 only to show the state in which part of the battery cell 31 is placed in the receiving cavity of the carrier 1. In the actual use of the bending equipment, after the battery 3 is installed, the first magnetic member 13 and the second magnetic member 14 attract each other, and the first support member 11, which is away from the rotation axis, abuts against the second support member 12, thereby fixing the battery 3.

[0041] Optionally, the bending assembly 2 further includes a second bending drive and a connecting member 22. The adsorption member 21 is fixed to the connecting member 22, and the connecting member 22 is connected to the first bending drive. The first bending drive is connected to the second bending drive, and the second bending drive can drive the first bending drive to move along a third direction L3, thereby matching the position of the adsorption member 21 with the battery protection board 32. Optionally, the second bending drive can be a cylinder.

[0042] Alternatively, the first bending drive can also be a robotic arm. In this case, the first bending drive can move the adsorption component 21 and rotate it, and there is no need to set up a second bending drive.

[0043] Furthermore, the adsorption member 21 includes an adsorption surface located on one side of the adsorption member 21 in the first direction L1. The adsorption surface has adsorption holes. When the battery protection board 32 is bent, the adsorption surface fits into the battery protection board 32, thereby adsorbing the battery protection board 32.

[0044] Optionally, such as Figure 3 As shown, the bending assembly 2 may further include a limiting block 23, which has an arc-shaped limiting groove 231. The limiting block 23 is connected to the second bending drive member. When the adsorption member 21 moves to a position where it can adsorb the battery protection board 32, a portion of the battery cell 31 and a portion of the battery protection board 32 are located within the limiting groove 231. During the bending process of the battery protection board 32, the battery protection board 32 flips within the limiting groove 231. Furthermore, the installation position of the limiting block 23 will not interfere with the connecting block and the adsorption member 21, ensuring that the bending of the battery protection board 32 can proceed smoothly.

[0045] like Figure 1 , Figure 5 and Figure 6 As shown, the bending equipment also includes a frame 5 and an adjustment assembly 6. The adjustment assembly 6 includes an adjustment drive mechanism, a first adjustment block 61, and a second adjustment block 62. The movable structure is fixed on the frame 5. The first adjustment block 61 and the second adjustment block 62 are respectively connected to the adjustment drive mechanism, which can drive the first adjustment block 61 and the second adjustment block 62 to move. The first adjustment block 61 includes a first contact surface S1, which is perpendicular to the first direction L1. The second adjustment block 62 includes a second contact surface S2, which is perpendicular to the second direction L2. Both the first contact surface S1 and the second contact surface S2 can be in contact with the battery protection board 32. Thus, the position of the battery protection board 32 can be adjusted by the first adjustment block 61 and the second adjustment block 62, so that the adsorption member 21 can accurately adsorb the battery protection board 32.

[0046] Optionally, the adjustment drive mechanism includes a first adjustment drive member 63, a second adjustment drive member 64, a third adjustment drive member 65, and a fourth adjustment drive member 66. The first adjustment drive member 63 is fixed on the frame 5. The second adjustment drive member 64 and the third adjustment drive member 65 are both connected to the first adjustment drive member 63. The first adjustment drive member 63 can drive the second adjustment drive member 64 and the third adjustment drive member 65 to move along a first direction L1. The second adjustment drive member 64 is connected to the first adjustment block 61. The second adjustment drive member 64 can drive the first adjustment block 61 to move along a third direction L3. The fourth adjustment drive member 66 is connected to the third adjustment drive member 65. The third adjustment drive member 65 can drive the fourth adjustment drive member 66 to move along a third direction L3. The fourth adjustment drive member 66 is connected to the second adjustment block 62. The fourth adjustment drive member 66 can drive the second adjustment block 62 to move along a second direction L2. Thus, the positions of the first adjustment block 61 and the second adjustment block 62 can be adjusted by the first adjustment drive 63, the second adjustment drive 64, the third adjustment drive 65 and the fourth adjustment drive 66, thereby adjusting the position of the battery protection board 32.

[0047] Optionally, the first adjustment drive 63, the second adjustment drive 64, the third adjustment drive 65 and the fourth adjustment drive 66 are all cylinders.

[0048] In the embodiments of this application, such as Figure 2 and Figure 7 As shown, the bending equipment also includes a pre-insertion assembly 7, which includes a pre-insertion drive mechanism 71 and a pre-insertion block 72. The pre-insertion drive mechanism 71 is fixed on the frame 5. The pre-insertion block 72 includes a fixed end 721 and a tip 722. The fixed end 721 is connected to the pre-insertion drive mechanism 71, which can drive the pre-insertion block 72 to move. The tip 722 is used to contact the battery protection board 32. In the direction from the fixed end 721 to the tip 722, the size of the pre-insertion block 72 gradually decreases in the third direction L3. Before bending the battery protection board 32, the pre-insertion block 72 moves under the drive of the pre-insertion drive mechanism 71 until the tip 722 of the pre-insertion block 72 contacts the bottom of the part of the battery protection board 32 to be bent, thereby locking the battery protection board 32. The process of the first bending drive causing the adsorption component 21 to flip can be divided into two stages. In the first stage, the tip 722 of the pre-insertion block 72 abuts against the bottom of the part of the battery protection board 32 to be bent. At this time, the first bending drive rotates 30 degrees, causing the battery protection board 32 to bend initially. Then, the pre-insertion block 72 moves out, and the first bending drive rotates to 88 degrees, thereby completing the bending of the battery protection board 32. The setting of the pre-insertion block 72 ensures that the battery protection board 32 bends at the bottom of the part to be bent, ensuring the accuracy of the bending of the battery protection board 32.

[0049] Furthermore, the pre-insertion drive mechanism 71 includes a first pre-insertion drive member 711 and a second pre-insertion drive member 712. The first pre-insertion drive member 711 is fixed on the frame 5, and the second pre-insertion drive member 712 is connected to the first pre-insertion drive member 711. The first pre-insertion drive member 711 can drive the second pre-insertion drive member 712 to move along a third direction L3. The fixed end 721 moves with the second pre-insertion drive member 712, and the second pre-insertion drive member 712 can drive the pre-insertion block 72 to move along a predetermined direction. The angle between the predetermined direction and the plane defined by the first direction L1 and the second direction L2 is an acute angle. In this way, the tip 722 of the pre-insertion block 72 can move in an inclined manner to contact the bottom of the pre-insertion block 72 and the bottom of the portion of the battery protection board 32 to be bent, so as to avoid the tip 722 of the pre-insertion block 72 applying force to other parts of the battery protection board 32 and causing damage to the battery protection board 32.

[0050] Optionally, both the first pre-insertion drive 711 and the second pre-insertion drive 712 are cylinders.

[0051] When using the bending equipment, the mounting platform 42 is first moved to the first position, and the carrier 1 with the battery cell 31 is placed on the first support plate so that the carrier 1 contacts the first contact surface and the second contact surface respectively. Then, the first telescopic member 43 and the second telescopic member 44 extend, so that the first contact surface, the second contact surface, the first telescopic member 43 and the second telescopic member 44 all contact the carrier 1, thereby fixing the carrier 1. Then, the mounting platform 42 moves to the position corresponding to the detection component, so that the detection component detects the position of the battery 3. Then, the mounting platform 42 moves to the second position, and then the driving junction drives the first adjusting block 61 and the second adjusting block 62 to move, thereby adjusting the position of the battery protection plate 32. Then, the first adjusting block 61 and the second adjusting block 62 move out, and the adsorption member 21 moves to the position of contacting the battery protection plate 32 and adsorbs the battery protection plate 32. The tip 722 of the pre-insertion block 72 moves to the bottom of the battery protection plate 32 to be bent. The first bending drive rotates 30 degrees, causing the battery protection plate 32 to be initially bent. Then the pre-insertion block 72 moves out, and the first bending drive rotates to 88 degrees, thereby completing the bending of the battery protection plate 32. Then the adsorption member 21 flips and resets, and moves out along the third direction L3. Then the mounting platform 42 moves to the first position, at which point the carrier 1 can be released and the battery 3 can be removed from the carrier 1.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
