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

[0051] like Figure 1 As shown, during the processing of the battery 2000 , after the welding of the tab 2300 and the cover plate 2100 is completed, the two cover plates 2100 need to be sealed and buckled together with the opening of the battery shell 2200 to achieve the sealed accommodation of the battery cell in the battery shell 2200 .

[0052] In the prior art, for the buckling of the cover plate 2100 and the battery housing 2200, a cover closing device is usually used to move the cover plate 2100 connected to the tab 2300 to face the opening of the battery housing 2200, and then drive the cover plate 2100 to move in a direction close to the battery housing 2200 to complete the buckling and fixing of the cover plate 2100 and the opening of the battery housing 2200. However, when the above-mentioned cover closing device is used to close the cover of a cylindrical battery, since the cover plate and the opening of the cylindrical battery are both circular, after the cover plate and the opening on the battery housing are buckled, relative deflection will occur between the two cover plates fixed on the battery housing, making subsequent inspection work more cumbersome and difficult, and also reducing the inspection efficiency and affecting the appearance of the product.

[0053] In order to solve the above problems, Figure 2 and Figure 3 As shown, this embodiment provides a cover-closing correction device 1000. The cover-closing correction device 1000 is used to correct the cover plate 2100 during the closing process of the battery housing 2200 and the cover plate 2100. Specifically, the cover-closing correction device 1000 includes a cover-closing correction module, and the cover-closing correction module includes a picking mechanism 200 and a rotation correction mechanism 100, wherein the picking mechanism 200 is used to pick up the cover plate 2100, and the output end of the rotation correction mechanism 100 is connected to the picking mechanism 200 and is used to drive the picking mechanism 200 to drive the cover plate 2100 to rotate around the central axis of the cover plate 2100, so as to adjust the relative deflection angle of the cover plate 2100 at both ends of the battery housing 2200 to zero.

[0054] The cover closing and correcting device 1000 is provided with a cover closing and correcting module, and utilizes the picking mechanism 200 in the cover closing and correcting module to pick up the cover plate 2100, so as to realize the picking and fixing of the cover plate 2100, and connects the output end of the rotational correction mechanism 100 in the cover closing and correcting module with the picking mechanism 200, so that the rotational correction mechanism 100 can drive the picking mechanism 200 and then drive the cover plate 2100 on the picking mechanism 200 to rotate around the central axis of the cover plate 2100, so that the cover plate 2100 fixed on the picking mechanism 200 rotates around its own central axis relative to the other cover plate 2100, so as to ensure that the relative deflection angle of the two cover plates 2100 is zero, and when the subsequent cover plate 2100 is buckled with the battery shell 2200, it can ensure that the relative deflection angle of the two cover plates 2100 buckled on the battery shell 2200 is zero, which not only facilitates the subsequent detection process, but also improves the aesthetics of the product.

[0055] Furthermore, the cover closing correction device 1000 also includes a space moving module, the output end of the space moving module is connected to the cover closing correction module and is used to drive the cover closing correction module to move in the front-to-back direction, the left-to-right direction and the vertical direction, so as to realize the picking and fixing of the picking mechanism 200 and the cover plate 2100 in the cover closing correction module and the snap-fitting and fixing of the cover plate 2100 fixed on the picking mechanism 200 and the battery shell 2200.

[0056] Specifically, if Figure 2 and Figure 3 As shown, the spatial moving module includes a front-to-back moving mechanism 300, a left-to-right moving mechanism 400 and an up-and-down moving mechanism 500, wherein the output end of the up-and-down moving mechanism 500 is connected to the rotation correction mechanism 100 in the cover correction module and is used to drive the rotation correction mechanism 100 to drive the picking mechanism 200 to move in the vertical direction (up-and-down direction in the figure), the output end of the left-and-right moving mechanism 400 is connected to the up-and-down moving mechanism 500 and is used to drive the up-and-down moving mechanism 500 to move in the left-and-right direction, the output end of the front-to-back moving mechanism 300 is connected to the left-and-right moving mechanism 400 and is used to drive the left-and-right moving mechanism 400 to move in the front-to-back direction, and the front-to-back direction is the same as the length direction of the battery housing 2200. By configuring the spatial moving module to be an up and down moving mechanism 500, a left and right moving mechanism 400, and a front and back moving mechanism 300, connecting the output end of the up and down moving mechanism 500 to the rotating correction mechanism 100 in the cover closing correction module, connecting the output end of the left and right moving mechanism 400 to the up and down moving mechanism 500, and connecting the input end of the front and back moving mechanism 300 to the left and right moving mechanism 400, the spatial moving module as a whole can drive the cover closing correction module and the cover plate 2100 to move in the front and back directions, the nausea direction, and the up and down directions, thereby realizing the picking and fixing of the cover plate 2100 by the picking mechanism 200 in the cover closing correction module and the snapping and fixing of the cover plate 2100 fixed on the picking mechanism 200 to the battery shell 2200.

[0057] It should be noted that, in other embodiments, the specific connection sequence of the front and rear transfer mechanism 300, the left and right transfer mechanism 400, and the up and down transfer mechanism 500 can be adjusted arbitrarily. It is only necessary to ensure that the spatial moving module can respectively drive the closing and correcting module and the cover plate 2100 connected thereto to move in the front and rear directions, the left and right directions, and the up and down directions respectively. This embodiment does not make any specific limitations.

[0058] In this embodiment, the space moving module and the cover correction module connected thereto cooperate to form a set of cover correction modules, and the two sets of cover correction modules are arranged at intervals in the front-to-back direction, and are respectively used for the correction and closing of the cover plates 2100 at both ends of a battery housing 2200. By forming a set of cover correction modules with the space moving module and the cover correction module connected thereto, and arranging two sets of cover correction modules at intervals in the front-to-back direction, so that the two sets of cover correction modules correspond to the two cover plates 2100 at both ends of the battery housing 2200, respectively, the cover plates 2100 at both ends of the battery housing 2200 can be corrected synchronously at the same time, thereby improving the rotation correction efficiency of the two cover plates 2100.

[0059] In other embodiments, only one set of cover correction module may be provided, and an additional set of space moving modules and a picking mechanism 200 connected to the space moving modules may be provided. The space moving modules and the picking mechanism 200 are spaced apart from the cover correction module in the front-to-back direction, so that the picking mechanism 200 in the space moving module clamps and fixes one end cover plate 2100 of the battery shell 2200, and the picking mechanism 200 in the cover correction module clamps the other end cover plate 2100 of the battery shell 2200, and drives the cover plate 2100 to rotate relative to the other cover plate 2100, so that the deflection angle between the two cover plates 2100 is zero, and then the two cover plates 2100 are respectively fastened and fixed to the battery shell 2200. This embodiment does not make specific limitations.

[0060] As an optional solution, the cover correction device 1000 also includes a conveying module, which is located between two sets of cover correction modules arranged relatively to each other, and the conveying module is used to convey the battery shell 2200 in the left and right direction. By arranging a conveying mechanism extending in the left and right direction between two sets of cover correction modules arranged relatively to each other in the front and back directions to convey the battery shell 2200, it is possible to realize the automatic loading and unloading of the battery shell 2200 in the cover correction device 1000, thereby improving the buckling efficiency of the cover plate 2100 and the battery shell 2200. It should be noted that in other embodiments, the two sets of cover correction modules can also be arranged relatively to each other in the left and right directions or other directions. It is only necessary to ensure that the conveying module is arranged between the two sets of cover correction modules arranged relatively to each other, and the battery shell 2200 is conveyed in a direction perpendicular to the relative arrangement direction of the two sets of cover correction modules. This embodiment does not make specific limitations.

[0061] In addition, in this embodiment, the conveying module is a conveyor belt structure, which has a stable output and a good transfer effect. In other embodiments, the conveying module can also be a six-axis manipulator or other conveying structure, which is not specifically limited in this embodiment.

[0062] In an optional embodiment, the cover closing and deviation correction device 1000 further includes a positioning module, which includes a stand 700 and a positioning mechanism 600 installed on the stand 700. The positioning mechanism 600 is used to position the battery housing 2200 on the conveying module, so that the picking mechanism 200 can pick up the cover plate 2100 connected to the battery housing 2200. By setting the positioning module to position the battery housing 2200 on the conveying module, when the cover plate 2100 and the battery housing 2200 are fastened and fixed, the battery housing 2200 can be prevented from being moved by force, thereby further ensuring the fastening and fixing effect of the cover plate 2100 and the battery housing 2200.

[0063] In an optional embodiment, the cover closing correction device 1000 also includes a detection mechanism, wherein the detection mechanism is used to detect position information and deflection angle information of the cover plate 2100, and the rotation correction mechanism 100, the front and rear transfer mechanism 300, the left and right transfer mechanism 400, and the up and down transfer mechanism 500 are all connected to the detection mechanism signal, and the rotation correction mechanism 100 can drive the cover plate 2100 to rotate along the central axis of the cover plate 2100 according to the deflection angle information, and the front and rear transfer mechanism 300, the left and right transfer mechanism 400, and the up and down transfer mechanism 500 can drive the picking mechanism 200 to move in the front and rear directions, left and right directions, and up and down directions according to the position information. By setting up a detection mechanism to detect the position information and deflection angle information of the cover plate 2100, it is not only convenient for the front and rear transfer mechanism 300, the left and right transfer mechanism 400 and the up and down transfer mechanism 500 to jointly drive the picking mechanism 200 to pick up and fix the cover plate 2100, and drive the cover plate 2100 to accurately fit with the opening of the battery shell 2200, but also convenient for the rotation correction mechanism 100 to drive the cover plate 2100 to rotate along its central axis to ensure that the relative deflection angle between the two cover plates 2100 is zero, thereby ensuring the correction effect on the cover plate 2100.

[0064] It should be noted that, in the present embodiment, the detection mechanism includes a CCD detection camera (Charge Coupled Device) and a control unit. The CCD camera shoots the cover plate 2100 in real time. The control unit is used to detect the image shot by the CCD. A preset zero point is set in the control unit. When the rotation correction mechanism 100 drives the cover plate 2100 to rotate to the preset zero point, the control unit transmits the detection information to the rotation correction mechanism 100. The rotation correction mechanism 100 stops after receiving the detection information, so that the cover plate 2100 rotates to the preset zero point, and the rotation correction of the cover plate 2100 is completed. The CCD detection camera is compact, light, and has high detection accuracy and high sensitivity. The detection principles of the CCD camera and the control unit belong to the prior art and will not be repeated here.

[0065] Combination Figure 4The specific structure of the picking mechanism 200 is described. The picking mechanism 200 includes a picking bracket 230, a picking drive 220, and at least two circumferentially arranged clamping jaws 210, wherein the picking drive 220 is mounted on the picking bracket 230 and is used to drive all the clamping jaws 210 to approach each other to pick up the cover plate 2100, or drive all the clamping jaws 210 to move away from each other to release the cover plate 2100. By providing at least two clamps 210 connected to the pick-up drive 220, when it is necessary to pick up the cover plate 2100, the pick-up drive 220 first drives all the clamps 210 to move away from each other, so that a space for accommodating the cover plate 2100 is formed between all the clamps 210, and then the front and rear transfer mechanism 300, the left and right transfer mechanism 400, and the up and down transfer mechanism 500 jointly drive all the clamps 210 to move relative to the cover plate 2100, so that the cover plate 2100 moves to the space formed by the divergence of all the clamps 210, and then the pick-up drive 220 drives all the clamps 210 to move closer to each other to clamp and fix the cover plate 2100 located in the space. When it is necessary to release the cover plate 2100 clamped and fixed on the clamps 210, the pick-up drive 220 drives all the clamps 210 to move away from each other to release the cover plate 2100 fixed between all the clamps 210.

[0066] It should be noted that, in this embodiment, the picking mechanism 200 includes three clamps 210, which are circumferentially arranged on the picking drive 220 and connected to the picking drive 220, and the picking drive 220 can synchronously drive the three clamps 210 to gather together or diverge from each other. In other embodiments, the specific number of the clamps 210 can also be adjusted according to actual needs, and this embodiment does not specifically limit it.

[0067] In other embodiments, the picking mechanism 200 may also adsorb and fix the cover plate 2100 by means of a vacuum suction cup or magnetic suction, etc., which is not specifically limited in this embodiment.

[0068] Furthermore, the rotational deflection correction mechanism 100 includes a deflection correction drive member 110 and a deflection correction transmission member 120 arranged at intervals in the vertical direction. The deflection correction drive member 110 is used to drive the output end of the deflection correction transmission member 120 to rotate, and the output end of the deflection correction transmission member 120 is connected to the pick-up bracket 230. In actual application scenarios, due to limited installation space, it is impossible to ensure the coaxial installation of the deflection correction drive member 110 and the pick-up mechanism 200. The deflection correction transmission member 120 is provided to arrange the deflection correction drive member 110 and the deflection correction transmission member 120 at intervals in the vertical direction, and to ensure that the output end of the deflection correction transmission member 120 is connected to the pick-up bracket 230, and the rotation axis of the output end of the deflection correction transmission member 120 coincides with the center line of the circle where all the clamps 210 are located, which can save installation space while ensuring the rotational deflection correction effect on the cover plate 2100.

[0069] It should be noted that, in this embodiment, the deflection correction drive member 110 is a rotary motor, which drives the cover plate 2100 on the pickup mechanism 200 to rotate along the central axis of the cover plate 2100. The rotary motor has a simple structure, is easy to disassemble and assemble, and has a stable output power. In other embodiments, the deflection correction drive member 110 may also be a rotary cylinder or other rotary drive structure, which is not specifically limited in this embodiment.

[0070] In addition, in the present embodiment, the deflection correction drive member 120 is a synchronous belt, the input wheel of the synchronous belt is connected to the output end of the deflection correction drive member 110, and the output wheel of the synchronous belt is connected to the pickup mechanism 200. When the output end of the deflection correction drive member 110 rotates, the output end of the deflection correction drive member 110 drives the input wheel of the synchronous belt to rotate, the input wheel of the synchronous belt drives the transmission belt of the synchronous belt to rotate, the transmission belt in turn drives the output wheel to rotate, and the output wheel drives the pickup mechanism 200 to rotate, so as to achieve the effect of driving the cover plate 2100 on the pickup mechanism 200 to rotate along its central axis under the premise of changing the transmission direction of the deflection correction drive member 110.

[0071] As an alternative, Figure 5 As shown, the up and down transfer mechanism 500 includes a first mounting frame 520, a lifting frame 530 and an up and down driving member 510, wherein the first mounting frame 520 is connected to the output end of the left and right transfer mechanism 400, the lifting frame 530 is slidably installed on the first mounting frame 520 along the vertical direction, the lifting frame 530 is used to install the connecting bracket 130, and the up and down driving member 510 is installed on the first mounting frame 520 and is used to drive the lifting frame 530 to move in the vertical direction. By slidably installing the lifting frame 530 on the first mounting frame 520 and fixing the connecting bracket 130 on the lifting frame 530, the upper and lower driving members 510 drive the lifting frame 530 to move in the vertical direction, so as to drive the picking mechanism 200 and the cover plate 2100 fixed on the picking mechanism 200 to move in the vertical direction. Moreover, the sliding cooperation between the lifting frame 530 and the first mounting frame 520 can also provide guidance for the movement of the picking mechanism 200 and the cover plate 2100 fixed on the picking mechanism 200 in the vertical direction, thereby ensuring the driving accuracy.
