In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0036] In the battery production line, the battery passes through each processing step in sequence through the conveyor belt of the conveyor device to complete the battery preparation process. In the bending process of the battery cover, the cover is bent by a battery bending device. The existing battery bending device includes a bending mechanism and a positioning mechanism. The positioning mechanism is used to fix the pole ears connected to the cover, and the bending mechanism is used to achieve secondary bending of the cover. Since the sizes of different types of batteries are also different, the positioning mechanism and the bending mechanism can only bend the cover of a single size of battery. When the size of the battery changes, the positioning mechanism and the bending mechanism are prone to interfere with the battery, and the versatility is poor.

[0037] To solve the above problems, Figure 1 to Figure 4 As shown, this embodiment provides a battery bending device, which includes two bending mechanisms arranged opposite to each other to respectively bend two cover plates of the battery 10. It should be noted that the structures and operation processes of the two bending mechanisms are the same, so that the two bending mechanisms respectively bend the cover plates at both ends of the battery 10 in the axial direction at the same time.

[0038] Specifically, the bending mechanism includes a support frame 1, a bending assembly 3, an upper positioning assembly 4 and a lower positioning assembly 5, and at least one adjustment plate 2 is rotatably mounted on the support frame 1. The bending assembly 3 is arranged on the corresponding adjustment plate 2, and the bending assembly 3 can bend the cover plate. The upper positioning assembly 4 is installed on the support frame 1, and the upper positioning assembly 4 includes an upper positioning block 42 with an adjustable position, and the upper positioning block 42 can be pressed against the upper surface of the pole ear connected to the cover plate. The lower positioning assembly 5 is installed on the support frame 1, and the lower positioning assembly 5 includes a lower positioning block 52 with an adjustable position, and the lower positioning block 52 can be pressed against the lower surface of the pole ear, so that the upper positioning block 42 and the lower positioning block 52 can clamp the pole ear together. When bending the cover plates of different types of batteries 10, the positions of the upper positioning block 42 and the lower positioning block 52 are adaptively adjusted so that the upper positioning block 42 and the lower positioning block 52 can be clamped together to the pole ear connected to the cover plate. The adjustment plate 2 is rotated according to the different sizes of batteries 10 to adjust the installation angle of the bending assembly 3 on the support frame 1, so that the bending assembly 3 is adapted to the batteries 10 of different sizes, avoiding interference between the bending assembly 3 and the battery 10 when bending the cover of the battery 10, thereby expanding the application range of the battery bending device and improving the versatility.

[0039] like Figure 1 and Figure 2As shown, the battery bending device also includes a pressing mechanism 8, which includes a pressing drive 81 and a pressing block 82. The pressing drive 81 is located between the two bending mechanisms, and the output end of the pressing drive 81 is connected to the pressing block 82 to drive the pressing block 82 to press or release the battery 10. When the battery 10 moves to the middle of the two bending mechanisms, the pressing drive 81 drives the pressing block 82 to move downward to press the battery 10 (that is, to press the battery 10 in the carrier of the conveyor belt or the transmission belt), so as to press and position the battery 10 to prevent the battery 10 from being misplaced when the cover plate is bent.

[0040] Specifically, the pressing mechanism 8 further includes a pressing bracket 83, which is located on one side of one of the bending mechanisms and extends to the top of the two bending mechanisms, and the pressing driving member 81 is fixedly mounted on the pressing bracket 83. The pressing driving member 81 of this embodiment is a cylinder, which has a simple structure, is easy to maintain, and has high control accuracy, and can accurately control the lifting and lowering movement of the pressing block 82.

[0041] It should be noted that the tabs extending from both ends of the battery 10 are respectively welded to a cover plate. When the battery 10 is moved between the two bending mechanisms, the cover plate is prone to shaking and shifting due to the thin tabs. Figure 3 and Figure 4 As shown, the bending mechanism also includes a correction component 7, which includes a correction drive 71 and a correction module 72. The correction drive 71 is arranged on the support frame 1. The correction drive 71 is connected to the correction module 72 in a transmission manner to drive the correction module 72 to move between a correction position for clamping or releasing the cover plate and a avoidance position away from the cover plate. By installing the correction component 7 on the bending mechanism, the correction components 7 in the two bending mechanisms can clamp and position the cover plates on both sides of the battery 10 axially, respectively, to ensure the bending accuracy of the cover plates.

[0042] Specifically, the correction module 72 includes a correction module group 721 and a clamping claw group 722, the output end of the correction driving member 71 is connected to the correction module group 721, and the output end of the correction module 72 is connected to the clamping claw group 722 to drive the clamping claw group 722 located at the correction position to clamp or release the cover plate. The above-mentioned correction driving member 71 and the correction module group 721 are both cylinders, and the cylinder structure is simple, convenient for maintenance, and has high control accuracy. The clamping claw group 722 has two clamping claws. When the battery 10 arrives between the two bending mechanisms, the correction driving member 71 drives the correction module 72 to move the correction position, at which time the clamping claw group 722 remains in an open state, and the cover plate is located between the two clamping claws. The correction module group 721 drives the two clamping claws to clamp the cover plate, and then the correction module 721 drives the clamping claw group 722 to reopen, and the correction driving member 71 drives the correction module 72 to return to the avoidance position to avoid interference with the subsequent bending process of the cover plate.

[0043] like Figure 3 and Figure 5 As shown, the lower positioning assembly 5 also includes a lower positioning driving member 51, which drives the lower positioning block 52 to rise to press against the lower surface of the pole ear; or, the lower positioning driving member 51 drives the lower positioning block 52 to descend to stay away from the pole ear. The lower positioning driving member 51 of this embodiment is a cylinder, which has a simple structure, is easy to maintain, and has high control accuracy, and can accurately control the lifting and lowering movement of the lower positioning block 52.

[0044] Furthermore, the lower positioning assembly 5 further includes a first adapter plate 53 and a second adapter plate 54. The output end of the lower positioning drive member 51 is connected to the first adapter plate 53 to drive the first adapter plate 53 to move up and down. One end of the second adapter plate 54 is arranged along the direction of the two bending mechanisms ( Figure 5 The lower positioning block 52 is height-adjustably mounted on the other end of the second adapter plate 54. When the size of the battery 10 changes, the second adapter plate 54 can move in the left-right direction, and the lower positioning block 52 can be lifted and moved in the up-down direction to adjust the position of the lower positioning block 52 in both the left-right direction and the up-down direction, so that the lower positioning block 52 can be flexibly adjusted according to the different sizes of the battery 10 to ensure that the lower positioning block 52 is accurately pressed against the lower surface of the tab.

[0045] like Figure 4 As shown, the upper positioning assembly 4 of this embodiment is installed obliquely on the support frame 1 to avoid the downward pressing driving member 81 and the downward pressing block 82 in the downward pressing mechanism 8. In order to adjust the position of the upper positioning block 42, two adjustment plates 2 are rotatably installed on each support frame 1 of this embodiment, one of the adjustment plates 2 is provided with a bending assembly 3, and the other adjustment plate 2 is provided with an upper positioning assembly 4. Specifically, the bending assembly 3 is installed on the adjustment plate 2 located at the bottom, and the upper positioning assembly 4 is installed on the adjustment plate 2 located at the top.

[0046] The position of the upper positioning block 42 can be adjusted by adjusting the tilt angle of the adjustment plate 2 where the upper positioning assembly 4 is located, thereby ensuring that the upper positioning block 42 is accurately pressed against the upper surface of the pole lug, so that the upper positioning block 42 and the lower positioning block 52 can clamp the pole lug together.

[0047] Specifically, the upper positioning assembly 4 also includes an upper positioning drive 41, which is installed on the upper adjustment plate 2 and drives the upper positioning block 42 to be pressed against or away from the upper surface of the pole ear. The upper positioning drive 41 of this embodiment is a cylinder, which has a simple structure, is easy to maintain, and has high control accuracy, and can accurately control the movement of the upper positioning block 42.

[0048] like Figure 4As shown, the bending assembly 3 includes a bending drive 31 and a bending roller 32. The bending drive 31 is installed on the adjustment plate 2 located below. The output end of the bending drive 31 is connected to the bending roller 32 to drive the bending roller 32 to move obliquely downward. When the adjustment plate 2 located below is adjusted to the right position, the bending drive 31 drives the bending roller 32 to move downward and roll the cover plate to bend. The lower positioning block 52 has a bending guide inclined surface 521 that limits the bending angle of the cover plate. When the bending roller 32 rolls the cover plate, the pole ear is bent until it fits on the bending guide inclined surface 521 of the lower positioning block 52. When the bending drive 31 drives the bending roller 32 to reset and detach from the cover plate, the pole ear will rebound to a certain extent, so that the bending angle of the cover plate is approximately 90°.

[0049] In this embodiment, the two adjustment plates 2 on the same support frame 1 are both rotatably mounted through the corresponding rotating shafts 13, and the structures and adjustment processes of the two adjustment plates 2 are the same. For ease of description, the adjustment plate 2 with the bending drive member 31 installed is used as an example for explanation. When the size of the battery 10 changes, the adjustment plate 2 located below rotates around the corresponding rotating shaft 13 to adjust the inclination angle of the bending assembly 3, so that the bending roller 32 is adapted to batteries 10 of different sizes.

[0050] Specifically, Figure 2 As shown, the support frame 1 is provided with an arc-shaped slide groove 11, and the slide groove 11 takes the rotation center of the corresponding adjustment plate 2 (i.e., the axis center of the rotating shaft 13) as the center of the circle. The bending mechanism also includes a locking member 6, which passes through the slide groove 11 and cooperates with the adjustment plate 2 to lock or unlock the corresponding adjustment plate 2. When the size of the battery 10 changes, the locking member 6 unlocks the corresponding adjustment plate 2, and the inclination angle of the adjustment plate 2 is manually adjusted to adjust the initial position of the bending roller 32. When the adjustment plate 2 is adjusted into place, the locking member 6 locks the corresponding adjustment plate 2, so that the adjustment plate 2 is fixedly mounted on the support frame 1 to ensure the stability of the bending assembly 3. By providing the locking member 6, flexible adjustment and stable installation of the adjustment plate 2 are achieved.

[0051] The locking member 6 of this embodiment is threadedly connected with the corresponding adjustment plate 2. Specifically, the locking member 6 can be a screw, and the adjustment plate 2 is provided with a threaded hole threadedly connected with the screw. When the adjustment plate 2 needs to be rotated, it is only necessary to loosen the locking member 6, and the adjustment plate 2 rotates around the corresponding rotating shaft 13, and at the same time, the locking member 6 slides in the same direction as the adjustment plate 2 in the slide groove 11. When the adjustment plate 2 is adjusted to the right position, the locking member 6 can be tightened again to lock the adjustment plate 2 on the support frame 1, so that the entire adjustment process is simple and easy, and the adjustment efficiency is high.

[0052] Furthermore, a plurality of slide grooves 11 may be provided, and the plurality of slide grooves 11 are concentrically and spaced apart, and the plurality of locking members 6 are respectively passed through the corresponding slide grooves 11 and are threadedly connected to the adjustment plate 2, thereby improving the connection strength and stability between the adjustment plate 2 and the support frame 1. The larger the radius of the circle where the slide groove 11 is located, that is, the farther the slide groove 11 is from the corresponding rotating shaft 13, the greater the arc length of the slide groove 11; similarly, the smaller the radius of the circle where the slide groove 11 is located, that is, the closer the slide groove 11 is to the corresponding rotating shaft 13, the shorter the arc length of the slide groove 11. The present embodiment has two slide grooves 11. In other embodiments, the number of slide grooves 11 may also be three or more than four.

[0053] like Figure 2 As shown, the support frame 1 is provided with a visual slot 12 for displaying the adjustment plate 2, and the visual slot 12 is arc-shaped and is arranged concentrically with the slide slot 11. The outer edge of the visual slot 12 is provided with engraved lines showing the corresponding rotation angle of the adjustment plate 2 along the extension direction. The rotation direction of the adjustment plate 2 can be visually observed through the visual slot 12, and the engraved lines on the outer edge of the visual slot 12 can be used as a reference to accurately adjust the rotation angle of the adjustment plate 2, thereby improving the adjustment accuracy of the adjustment plate 2. Since the adjustment process of the adjustment plate 2 with the upper positioning component 4 installed is exactly the same as the adjustment process of the adjustment plate 2 with the bending component 3 installed, the position adjustment process of the upper positioning component 4 will not be repeated.

[0054] For ease of understanding, the bending process of the battery bending device of this embodiment is as follows:

[0055] When the battery 10 reaches the two bending mechanisms, all the locking pieces 6 of the two adjustment plates 2 are loosened, and the adjustment plates 2 in each bending mechanism are accurately rotated according to the engraved lines of the visible groove 12 according to the actual size of the battery 10. When the adjustment plates 2 are adjusted to the right position, all the locking pieces 6 are tightened. Then, the position of the second adapter plate 54 in the left-right direction and the height of the lower positioning block 52 in the up-down direction are adjusted according to the actual size of the battery 10.

[0056] When the battery 10 reaches the two bending mechanisms, the downward pressing drive 81 is started, and the downward pressing block 82 presses down and fixes the battery 10. The deflection correction drive 71 is started and pushes the deflection correction module 721 from left to right to move rightward to the deflection correction position. The deflection correction module 721 drives the two clamps of the corresponding clamping jaw group 722 to clamp the cover plate in the middle and then release, and the deflection correction drive 71 drives the deflection correction module 721 to retreat to the avoidance position again. The lower positioning drive 51 drives the lower positioning block 52 to rise and support the lower surface of the pole ear. At the same time, the upper positioning drive 41 drives the upper positioning block 42 to press down and press against the upper surface of the pole ear. Then, the bending drive 31 drives the bending roller 32 to tilt down to bend the cover plate, and the bending guide slope 521 of the lower positioning block 52 limits the bending degree of the cover plate. The bent pole ear rebounds, so that the bending angle of the cover plate is approximately 90°.

[0057] Finally, when the two cover plates are bent, the bending drive 31 drives the bending roller 32 to reset, the lower positioning drive 51 drives the lower positioning block 52 to descend and reset, the upper positioning drive 41 drives the upper positioning block 42 to reset, and the lower pressing drive 81 drives the lower pressing block 82 to release the battery 10. That is, after the two bending mechanisms complete the bending action, each component returns to its initial state, and the battery 10 enters the next workstation through the conveying device.

[0058] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
