[0031] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0032] like Figure 1 As shown, in one embodiment, the present invention discloses a battery string correction device, including a correction body 10, a first correction device 20, a second correction device 30, and a Z-axis moving device 40. The first correction device 20, the second correction device 30 and the Z-axis moving device 40 are all arranged on the correction body 10, and the first correction device 20 and the second correction device 30 are arranged opposite to each other.

[0033] The Z-axis moving device 40 is connected to the first deviation correcting device 20 and the second deviation correcting device 30 respectively, and the Z-axis moving device 40 drives the first deviation correcting device 20 and the second deviation correcting device 30 to move in the Z-axis direction. Figure 1 As shown, preferably, the Z-axis moving device 40 includes a moving beam 41, a first moving mechanism, and a second moving mechanism. The moving beam 41 is connected to the first moving mechanism and the second moving mechanism, respectively. The first correcting device 20 and the second correcting device 30 are respectively connected to the moving beam 41. The moving beams 41 are respectively arranged on two opposite sides of the correcting body 10.

[0034] like Figure 3 As shown, the first moving mechanism includes a first drive motor 42 and four vertically arranged electric cylinders 43. The four electric cylinders 43 are respectively arranged on opposite sides of the correcting body 10. The first drive motor 42 is located on one side of the correcting body 10 and between two of the electric cylinders 43. The first drive motor 42 is connected to a reducer 44. The reducer 44 is connected to two electric cylinders 43 on the same side via a drive shaft 45 and a coupling. The two electric cylinders 43 are respectively connected to two other electric cylinders 43 via a reducer 44 and a coupling. There are two movable beams 41, each connected to the two electric cylinders 43 on the same side. The first drive motor 42 drives the four electric cylinders 43, which in turn drive the two movable beams 41 to move in the Z-axis direction, thereby simultaneously driving the first and second correcting devices 20 and 30 in the Z-axis direction. The electric cylinders 43 in this embodiment can be any existing type of electric cylinder 43 that can perform the above-mentioned functions.

[0035] The second moving mechanism includes a plurality of moving cylinders 46. Preferably, the second moving mechanism includes four moving cylinders 46, two of which are connected to one moving beam 41, and the other two are connected to another moving beam 41. Preferably, the driving cylinder is a counterweight cylinder.

[0036] When the first drive motor 42 drives the four electric cylinders 43 to move the first and second correcting devices 20 and 30 upward via the moving crossbeam 41, the counterweight cylinder is activated, providing an upward thrust to the moving crossbeam 41. The counterweight cylinder and the first drive motor 42 drive the first and second correcting devices 20 and 30 upward, reducing the operating power of the first drive motor 42. When the first drive motor 42 drives the four electric cylinders 43 to move the first and second correcting devices 20 and 30 downward via the moving crossbeam 41, the counterweight cylinder is simultaneously deflated, relying on its own gravity to reduce the operating power of the first drive motor 42.

[0037] The first deviation-correcting device 20 and the second deviation-correcting device 30 of this embodiment have the same structure. Figure 2 As shown, the first correcting device 20 and the second correcting device 30 each include a plurality of correcting modules 21, and a plurality of X-axis moving mechanisms 22, a plurality of Y-axis moving mechanisms 23, and a plurality of rotating mechanisms 24 corresponding to and connected to each of the correcting modules 21. The plurality of correcting modules 21 are each provided with a plurality of suction nozzles 211. Preferably, the first correcting device 20 and the second correcting device 30 each include six correcting modules 21, six X-axis moving mechanisms 22, six Y-axis moving mechanisms 23, and six rotating mechanisms 24. The six rotating mechanisms 24 respectively drive the six correcting modules 21 to rotate, the six X-axis moving mechanisms 22 drive the six correcting modules 21 to move in the X-axis direction, and the six Y-axis moving mechanisms 23 drive the six correcting modules 21 to move in the Y-axis direction.

[0038] The first deviation-correcting device 20 and the second deviation-correcting device 30 further include two first movable guide rails 25 arranged opposite to each other. The opposite ends of the deviation-correcting module 21 are connected to the two first movable guide rails 25 via sliders.

[0039] The six X-axis moving mechanisms 22 are respectively disposed at opposite ends of the correction module 21 . Preferably, three X-axis moving mechanisms 22 are located at one end of the correction module 21 , and the other three X-axis moving mechanisms 22 are located at the other end of the correction module 21 .

[0040] The X-axis moving mechanism 22 of this embodiment includes a second drive motor 221 , a first lead screw 222 and a first connecting component. The second drive motor 221 is connected to the first connecting component via the first lead screw 222 , and the first connecting component is connected to the correction module 21 .

[0041] The first connecting assembly includes a first connecting plate 223, a second connecting plate 224 and a third connecting plate 225. The bottom of the first connecting plate 223 is connected to the first screw 222, the top of the first connecting plate 223 is connected to the second connecting plate 224, the second connecting plate 224 is connected to the third connecting plate 225, and the third connecting plate 225 is connected to the correction module 21.

[0042] The second drive motor 221 drives the first lead screw 222 to rotate. The first lead screw 222 drives the second connecting plate 224, the third connecting plate 225 and the correction module 21 to move through the first connecting plate 223. The correction module 21 is driven to move on the first guide rail through the X-axis moving mechanism 22.

[0043] like Figure 4As shown, each of the correcting modules 21 of this embodiment includes a nozzle fixing seat 212 , and a plurality of nozzles 211 are respectively fixed on two opposite sides of the nozzle fixing seat 212 . The correcting module 21 sucks the battery string through the nozzles 211 .

[0044] like Figure 4 As shown, the rotating mechanism 24 includes a rotating body 241 and a harmonic reducer 242. The rotating body 241 is fixed to the nozzle fixing base 212, and the harmonic reducer 242 is fixed to the rotating body 241. The harmonic reducer 242 is connected to the nozzle fixing base 212. When the harmonic reducer 242 rotates, it drives the nozzle fixing base 212 to rotate.

[0045] The Y-axis movement mechanism 23 includes a Y-axis movement body 231, a second movement rail 232, a third drive motor 233, and a second lead screw mounted on the Y-axis movement body 231. A rotating body 241 is connected to the second movement rail 232 via a slider. The third drive motor 233 is connected to the second lead screw, which is in turn connected to the slider on the second movement rail 232. The third drive motor 233 drives the second lead screw to rotate, which in turn drives the slider, which in turn drives the rotation body 241, which in turn drives the correction module 21.

[0046] During operation, the deflection correction device of this embodiment first moves the first deflection correction device 20 and the second deflection correction device 30 downward by a certain distance, after which the suction nozzle 211 picks up a half-cell battery string. The Z-axis movement device 40 then moves the first deflection correction device 20 and the second deflection correction device 30 upward by a predetermined distance. The X-axis movement mechanism 22, the rotation mechanism 24, and the Y-axis movement mechanism 23 then move the half-cell battery string to adjust its position, splicing the two half-cell battery strings into a full battery string.

[0047] The multiple correction modules 21 of this embodiment are respectively driven by separate X-axis moving mechanisms 22, Y-axis moving mechanisms 23, and rotating mechanisms 24 to achieve correction of the battery string. At the same time, the X-axis moving mechanism 22 of the present invention can drive the correction modules 21 to move according to the model and size of different battery strings, adjust the spacing between each correction module 21, and the Y-axis moving mechanism 23 drives the correction modules 21 to move, adjusting the distance between the multiple correction modules 21 of the first correction device 20 and the second correction device 30. This embodiment can achieve the conversion operation of the correction device through the X-axis moving mechanism 22 and the Y-axis moving mechanism 23, so that the correction device can meet the use requirements of battery strings of different sizes and models.

[0048] This embodiment can simultaneously realize the deviation correction and type change operations through the X-axis moving mechanism 22, the Y-axis moving mechanism 23 and the rotating mechanism 24. It has a simple structure, is easy to maintain, and has a low cost.

[0049] The battery string correction device of this embodiment may also be equipped with a position acquisition component. This position acquisition component may include a camera and an image sensor connected to the camera. The image sensor may be a CCD sensor or a CMOS sensor. This position acquisition component can obtain actual position images of the half-cell battery string from the first correction device 20 and the second correction device 30. Based on the actual position images and the theoretical position images, it calculates the amount of the half-cell battery string. It then controls the X-axis movement mechanism 22, the Y-axis movement mechanism 23, and the rotation mechanism 24 to adjust the position of the correction module 21 based on the correction amount. This position acquisition component can be any existing position acquisition component.
