[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] The following combination Figures 1 to 5 The utility model describes a cylindrical battery cell pole posture adjustment device.

[0043] like Figures 1 to 3 As shown, this embodiment provides a cylindrical battery cell pole posture adjustment device, comprising:

[0044] The battery cell placement seat 1 has a plurality of placement holes 11 on its end face for supporting one end of the cylindrical battery cell 4 with a pole; the battery cell placement seat 1 can be designed to be an elongated strip, and at the same time, the placement holes 11 can be designed to be distributed in two rows, so that multiple cylindrical battery cells 4 can be placed in the placement holes 11 in batches without affecting subsequent detection, and the adjustment mechanism 2 is arranged at the bottom of the battery cell placement seat 1, and the adjustment mechanism 2 includes a driving component 21 and a plurality of correction components 22, and the plurality of correction components 22 are all installed on the output end of the driving component 21; the driving component 21 is used to drive the plurality of correction components 22 to be respectively placed in the plurality of placement holes 11 to correct the position of the poles of the cylindrical battery cell 4, and by setting a plurality of correction components 22 and a plurality of cylindrical battery cells 4 for one-to-one correction, the driving component 21 can simultaneously drive the plurality of correction components 22 to move together, so that multiple cylindrical battery cells 4 can be corrected at the same time, and the correction efficiency is high; the detection mechanism 3 is arranged on one side of the battery cell placement seat 1 to detect the posture of the cylindrical battery cell 4 after correction.

[0045] It should be pointed out here that, in this embodiment, the pole of the cylindrical battery cell 4 is elliptical, and the placement hole 11 is in the shape of a step that is wide at the top and narrow at the bottom. The wide part of the placement hole 11 contacts the outer surface of the cylindrical battery cell 4, and the narrow part of the placement hole 11 is used to accommodate the elliptical pole at the lower end of the cylindrical battery cell 4. By designing the placement hole 11 into a stepped shape, it is ensured that the end face of the cylindrical battery cell 4 falls on the stepped surface while the elliptical pole is just avoided.

[0046] It can be understood that since the cylindrical battery cells 4 are distributed in two rows, the detection mechanism 3 can be symmetrically distributed on the front and rear sides of the battery cell placement seat 1 to detect the two rows of cylindrical battery cells 4 respectively. At the same time, the detection mechanism 3 can be connected to the upper side of the battery cell placement seat 1 through the mounting plate. After the adjustment mechanism 2 corrects the cylindrical battery cells 4, the detection end of the detection mechanism 3 is arranged relative to the pole at the upper end of the cylindrical battery cells 4.

[0047] Furthermore, in order to achieve an optimized configuration of the overall structure of the cylindrical battery cell pole posture adjustment device, a base 5 is also provided in this embodiment. The base 5 is connected to the lower side of the battery cell placement seat 1. The base 5 adopts a U-shaped design, which is convenient for placing the adjustment mechanism 2, so that the overall occupied space is reduced. The base 5 can adopt an integrated design, or it can be spliced ​​by multiple plates. In this embodiment, the base 5 adopts a design of a bottom plate and two side plates. The two side plates are symmetrically connected at the edges of the left and right sides of the bottom plate. The connection between the bottom plate and the side plates can be achieved by bolt connection or direct welding; at the same time, multiple hollow holes are opened on the side plates on both sides to make the overall structure lightweight.

[0048] like Figures 2 to 5 As shown, the adjustment mechanism 2 shown in this embodiment also includes:

[0049] The lifting assembly 23 is installed on the driving assembly 21 , and is used to drive the driving assembly 21 to move along the axial direction of the cylindrical battery core 4 .

[0050] Among them, the lifting assembly 23 includes two lifting cylinders 231, two guide rails 232, and two sliders 233; the two lifting cylinders 231 are symmetrically installed on the inner bottom wall of the base 5, and the output end of the lifting cylinder 231 is connected to the lower side of the driving assembly 21. The driving assembly 21 is driven up and down by the two lifting cylinders 231. The two lifting cylinders 231 can prevent the driving assembly 21 from shaking due to excessive load during movement. At the same time, the provision of two lifting cylinders 231 can also reduce the load pressure of the upgrading cylinder 231, making the moving process more stable; the two guide rails 232 are placed vertically and symmetrically connected to the two inner side walls of the base 5; one side of the two sliders 233 is symmetrically connected to the outer side of the driving assembly 21, and the other side of the two sliders 233 is respectively slidably connected to the two guide rails 232. Two sliders 233 and two guide rails 232 are used. The guide rails 232 and the sliders 233 are symmetrically arranged on the left and right sides of the driving assembly 21. The sliders 233 and the guide rails 232 play a guiding role, making the driving mechanism 21 slide more smoothly.

[0051] Furthermore, two through holes can be opened above the bottom plate of the base 5, and the two through holes are aligned with the two lifting cylinders 231 respectively, so that the air pipe connected to the lifting cylinder 231 can be connected and installed through the through holes.

[0052] like Figure 5 As shown, the driving assembly 21 shown in this embodiment includes:

[0053] The driving pulley 211 is installed at the output end of the driving member 214; the driving member 214 is used to drive the driving pulley 211 to rotate; multiple synchronous pulleys 212 are respectively connected to multiple correction columns 221 in a one-to-one correspondence; the synchronous belt 213 is wound around the outer circumference of the driving pulley 211 and multiple synchronous pulleys 212 in sequence.

[0054] The correction component 22 includes: a correction column 221, whose end face is provided with a slot 222 for accommodating the pole of the cylindrical battery cell 4. The correction column 221 adopts a cylindrical design with a diameter the same as the diameter of the cylindrical battery cell 4. The slot 222 is radially arranged on the upper end face of the correction column 221. The slot 222 is long and has a width that matches the width of the elliptical pole of the cylindrical battery cell 4. In this way, when the correction column 221 rotates, when the elliptical pole of the cylindrical battery cell 4 is exactly opposite to the slot 222, the elliptical pole can fall into the slot 222 to achieve correction.

[0055] It should be pointed out here that the driving member 214 shown in this embodiment can be a driving motor known in the art. The driving assembly 21 also includes a driving seat 215. A plurality of mounting holes are provided on the driving seat 215. The bearing seat 216 is connected in the mounting hole. The correction column 221 is installed in the bearing seat 216, so that the rotation process of the correction column 221 is more stable. The driving seat 215 can be a long flat plate. At the same time, in order to connect with the slider 233, vertical connecting plates can be provided on the left and right sides of the driving seat 215. The slider 233 is installed on the outside of the connecting plate. The upper end surface of the driving seat 215 can be provided with a through hole for the driving member 214 to pass through. This can increase the range of motion of the driving assembly 21 and make the size smaller when the overall structure is designed.

[0056] The driving pulley 211 and multiple synchronous pulleys 212 are arranged below the drive seat 215. The synchronous belt 213 adopts a double-sided toothed synchronous belt. Since the cylindrical battery cells 4 are distributed in two rows, the multiple synchronous pulleys 212 are also distributed in two rows. The driving pulley 211 is arranged on one side of the multiple synchronous pulleys 212. When the synchronous belt 213 is installed, it first meshes with the teeth of the driving pulley 211 through the belt teeth, and then passes through the multiple synchronous pulleys 212 in the first row in a wave-like distribution. After passing the last synchronous pulley 21 in the first row, the synchronous belt 213 is rotated in a direction opposite to the first row. 2, then it is wrapped around the second row of synchronous pulleys 212, and then it is wrapped around multiple synchronous pulleys 212 in the second row in a wave-like distribution. After it is wrapped around the last synchronous pulley 212 in the second row, it is connected to the active force 211. Since the synchronous belt 213 adopts a double-sided tooth design, this winding method can keep the driving force of each synchronous pulley 212 consistent, making the meshing transmission of the active pulley 211 and the synchronous pulley 212 more stable, avoiding insufficient driving force of some synchronous pulleys 212 when the cylindrical battery cell 4 is corrected, thereby affecting the correction effect.

[0057] like Figure 5As shown, the adjustment mechanism 2 shown in this embodiment also includes a tensioning assembly 24, which transmits power between the power source and the corresponding moving parts by arranging a driving pulley 211, a synchronous belt 213 and a synchronous pulley 212; at the same time, by movably arranging a tensioning assembly 24 on one side of the synchronous belt 213, the tensioning assembly 24 moves relative to the synchronous belt 213 to tension the synchronous belt 213 or loosen the synchronous belt 213, thereby realizing the adjustment of the tensioning degree of the synchronous belt 213, so that the synchronous belt 213 can maintain appropriate tension, while maintaining its transmission efficiency. The wear and aging of the synchronous belt 213 is reduced, and the problem that the conventional synchronous belt is prone to tension failure due to wear, aging and the like after long-term use, thereby affecting the transmission efficiency, is solved.

[0058] Specifically, in some embodiments, the tensioning assembly 24 includes a tensioning plate 241. The upper end surface of the driving seat 215 may be provided with a mounting hole for mounting the tensioning plate 241. Two adjustment shafts 242 may be provided in the tensioning plate 241. The lower ends of the adjustment shafts 242 are rotatably connected to a tensioning wheel 243.

[0059] In this embodiment, there are two tensioning wheels 243; the synchronous belt 213 is located between the two tensioning wheels 243 or the synchronous belt 213 is wrapped around the two tensioning wheels 243; the two tensioning wheels 131 are respectively connected to the lower ends of the two adjustment shafts 242, and the adjustment shafts 242 drive the two tensioning wheels 243 to move closer to or away from each other, or drive at least one of the tensioning wheels 243 to move closer to or away from the other tensioning wheel 131, so that the two tensioning wheels 243 produce relative movement, thereby reducing or increasing the distance between the two tensioning wheels 243. When the distance is reduced, the two tensioning wheels 131 squeeze the synchronous belt from the outside to the inside on both sides of the synchronous belt, thereby tensioning the synchronous belt;

[0060] At the same time, two screws can be set between the two adjusting shafts 242. The external threads of the two screws rotate in opposite directions and are respectively threadedly connected to the two sides of the nut 133. The two screws are respectively connected to the two adjusting shafts 242. A nut can be threadedly connected between the two screws. When the nut rotates, the two screws move horizontally under the action of the thread cooperation. At the same time, since the external threads of the two screws rotate in opposite directions, the movement directions of the two screws under the thread cooperation are opposite, that is, they move toward the direction of approaching the nut or move away from the nut at the same time; when the two screws move toward the direction of approaching the nut at the same time, the two tensioning wheels 243 are driven to approach each other; when the two screws move toward the direction away from the nut at the same time, the two tensioning wheels 243 are driven away from each other, so as to realize the adjustment of the tensioning degree of the synchronous belt 213. The structure is simple and convenient for personnel to operate.

[0061] In another embodiment, the adjustment mechanism 2 includes multiple clamping components, which are used to clamp the poles of multiple cylindrical battery cells 4 respectively to correct the positions of the poles of the cylindrical battery cells 4, and the poles of the cylindrical battery cells 4 are clamped by the clamping components.

[0062] Specifically, the clamping assembly includes: a plurality of claws, which are respectively arranged on the outside of the cylindrical battery core 4, and the claws are used to clamp the pole of the cylindrical battery core 4; a driving element, which is connected to the plurality of claws, and the driving element is used to drive the claws to move radially toward the pole of the cylindrical battery core 4; wherein the driving element can adopt a plurality of servo cylinders, and the plurality of servo cylinders are connected to the plurality of claws, and the servo cylinders drive the claws to move, so that the claws move and clamp the pole of the cylindrical battery core 4 for correction, and the plurality of claws can be distributed in a circumferential direction on the outside of the cylindrical battery core 4, and the plurality of servo cylinders can be controlled simultaneously. Working, multiple claws are moved closer to the poles of the cylindrical battery core 4 along the radial direction of the cylindrical battery core 4. After approaching and contacting, the multiple claws clamp the poles of the cylindrical battery core 4. At the same time, the driving element can also adopt multiple servo motors. The output end of the servo motor can be provided with a connecting rod structure. The end of the connecting rod structure is connected to the claws. The output shaft of the servo motor is rotated to drive the connecting rod structure to move. The connecting rod structure converts the rotational motion of the servo motor into the reciprocating linear motion of the claws, thereby driving the claws to approach the poles of the cylindrical battery core 4 and clamp the poles. The connecting rod structure can adopt a structure well known in the art.

[0063] like Figure 2 As shown, based on the solution shown in the above embodiment, the detection mechanism 3 shown in this embodiment includes:

[0064] Multiple height sensors 31 are arranged in a one-to-one correspondence with multiple cylindrical battery cells 4, and are used to detect the height values ​​of the cylindrical battery cells 4; a control component is connected to the adjustment mechanism 2 and multiple height sensors 31, and the control component is used to control the adjustment mechanism 2 to correct the multiple cylindrical battery cells 4, and judge whether the multiple cylindrical battery cells 4 are all corrected by the height values; wherein, the mounting plate can adopt an L-shaped design, and the horizontal parts of the two mounting plates are respectively connected to the front and rear sides of the battery cell placement seat 1, and multiple height sensors 31 are arranged at intervals on the upper side of the vertical part of the mounting plate. The L-shaped design is adopted, and the position of the height sensor 31 can be adjusted according to the position of the cylindrical battery cell 4, so that the detection result of the height sensor 31 is relatively accurate.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
