DETAILED DESCRIPTION

[0019] 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.

[0020] like Figures 1 to 4 As shown, an embodiment of the present application provides a battery cell alignment mechanism, including a conveyor belt 1, wherein the conveyor belt 1 includes a conveyor belt body, a base 2 is provided below the conveyor belt body, and a alignment frame 21 is fixedly connected to the base 2, and the alignment frame 21 is provided with a left alignment wheel assembly 211 and a right alignment wheel assembly 212 which can be approached to align the left and right sides of the battery cell, and also includes a rear alignment wheel assembly 213 which can align the rear side of the battery cell, and the alignment frame 21 is provided with a first drive assembly for driving the left alignment wheel assembly 211, the right alignment wheel assembly 212 and the rear alignment wheel assembly 213 to move toward the middle of the alignment frame 21, and the base 2 is provided with a second drive assembly for driving the rear alignment wheel assembly 213 to rotate above or below the conveyor belt body.

[0021] Specifically, the alignment frame 21 is a T-shaped frame.

[0022] During operation, the battery cells are transported by the conveyor belt 1. During transportation, the rear aligning wheel assembly is located below the conveyor belt body, allowing the battery cells to pass through the rear aligning wheel assembly 213 smoothly. At this time, the battery cells are located above the alignment frame 21, and the second drive assembly drives the rear aligning wheel assembly 213 to flip upward, so that the height of the rear aligning wheel assembly 213 is higher than the height of the battery cells. Then the first drive assembly drives the left aligning wheel assembly 211, the right aligning wheel assembly 212 and the rear aligning wheel assembly 213 to move closer to the middle of the alignment frame 21, so that the left aligning wheel assembly 211, the right aligning wheel assembly 212 and the rear aligning wheel assembly 213 center the battery cells.

[0023] The above structure is set up by setting a correction frame 21 on the base 2 of the conveyor belt 1, and setting a left correction wheel assembly 211, a right correction wheel assembly 212 and a rear correction wheel assembly 213 on the correction frame 21, and setting a first driving assembly that can move the left correction wheel assembly 211, the right correction wheel assembly 212 and the rear correction wheel assembly 213 toward the middle of the correction frame 21, so that the left correction wheel assembly 211, the right correction wheel assembly 212 and the rear correction wheel assembly 213 can simultaneously correct the left, right and rear sides of the battery cell, so that the left and right and front and back positions of the battery cell are accurate and the correction efficiency is high. A second driving assembly that can rotate the rear correction wheel assembly 213 to the bottom of the conveyor belt 1 is set, so that when the battery cell is transmitted from the rear side of the rear correction wheel assembly 213 to the correction frame 21, the rear correction wheel assembly 213 can be flipped to the bottom of the conveyor belt body, so that the rear correction wheel assembly 213 will not affect the transmission of the battery cell.

[0024] In this embodiment, the first driving assembly includes a first synchronous wheel 23 located on the rear side of the rear return wheel assembly 213, a second synchronous wheel 24 located on the left side of the left return wheel assembly 211, and a third synchronous wheel 25 located on the right side of the right return wheel assembly 212. The first synchronous wheel 23, the second synchronous wheel 24 and the third synchronous wheel 25 are all rotatably connected to the base 2, and the first synchronous wheel 23, the second synchronous wheel 24 and the third synchronous wheel 25 are connected by a synchronous belt 231. A motor 22 for driving the first synchronous wheel 23 to rotate is fixedly connected to the base 2, and the left return wheel assembly 211, the right return wheel assembly 212 and the rear return wheel assembly 213 are all engaged with the synchronous belt 231.

[0025] In this embodiment, a first guide wheel 26 is provided on the base 2 located between the first synchronous wheel 23 and the second synchronous wheel 24, which can tension the synchronous belt 231 between the first synchronous wheel 23 and the second synchronous wheel 24 to a right angle. A second guide wheel 27 is provided on the base 2 located between the first synchronous wheel 23 and the third synchronous wheel 25, which can tension the synchronous belt 231 between the first synchronous wheel 23 and the third synchronous wheel 25 to a right angle. The first slide rail 214, the second slide rail 215 and the third slide rail 216 are fixedly connected to the correction frame 21, and the first slide rail 214, the second slide rail 215 and the third slide rail 216 are respectively slidably connected to the first slider 2141, the second slider 2151 and the third slider 2161. The rear correction wheel assembly 213 is hinged to the first slider 2141, and the left correction wheel assembly 211 and the right correction wheel assembly 212 are fixedly connected to the second slider 2151 and the third slider 2161, respectively.

[0026] In this embodiment, a first clamping block 21411 is provided on the left side of the first slider 2141, a second clamping block 21511 is provided on the front side of the second slider 2151, and a third clamping block 21611 is provided on the rear side of the third slider 2161. The first clamping block 21411, the second clamping block 21511 and the third clamping block 21611 respectively include a first clamping groove, a second clamping groove and a third clamping groove. The first clamping groove, the second clamping groove and the third clamping groove are all clamped with a part of the synchronous belt 231.

[0027] During operation, when the motor 22 drives the first synchronous wheel 23 to rotate clockwise, the synchronous belt 231 rotates along the direction of the first synchronous wheel 23, the first guide wheel 26, the second synchronous wheel 24, the third synchronous wheel 25, the second guide wheel 27, and the first synchronous wheel 23. Since the first clamping block 21411, the second clamping block 21511 and the third clamping block 21611 are all clamped with a part of the synchronous belt 231, the first clamping block 21411, the second clamping block 21511 and the third clamping block 21611 move along the synchronous belt 231. Since the first clamping block 21411 is located on the left side of the first slider 2141, when the synchronous belt 231 rotates clockwise, the first clamping block 21411, the second clamping block 21511 and the third clamping block 21611 are all clamped with a part of the synchronous belt 231. When the needle moves, the first slider 2141 moves forward. Since the second clamping block 21511 is located on the front side of the second slider 2151, when the synchronous belt 231 moves clockwise, the second slider 2151 moves to the right. The third clamping block 21611 is located on the rear side of the third slider 2161. When the synchronous belt 231 moves clockwise, the third slider 2161 moves to the left, so that when the synchronous belt 231 moves clockwise, the first slider 2141, the second slider 2151 and the third slider 2161 all approach the middle part of the correction frame 21, so that the rear correction wheel assembly 213, the left correction wheel assembly 211, and the right correction wheel assembly 212 correct the battery cell.

[0028] In this embodiment, a protrusion 214111 is provided on the inner wall of the first engaging groove, which can press the synchronous belt 231 and the first engaging block 21411 tightly.

[0029] The above-mentioned structure is set up by setting a protrusion 214111 on the inner wall of the first clamping groove, so that the first clamping groove can tightly clamp the synchronous belt 231, so that the movement of the synchronous belt 231 can drive the first clamping block 21411 and the first slider 2141. It should be noted that the second clamping block 21511 and the third clamping block 21611 are also provided with a protrusion 214111.

[0030] In this embodiment, the second driving assembly includes a cylinder 3, and a connecting groove 217 is provided on the correction frame 21 located below the first slide rail 214. The bottom of the first slider 2141 is fixedly connected to a connecting block 21412, and the cylinder 3 is fixedly connected to the connecting block 21412. The output end of the cylinder 3 extends upward and is hinged to a first hinge block 31. The end of the first hinge block 31 away from the cylinder 3 is hinged to a second hinge block 32. The end of the second hinge block 32 away from the first hinge block 31 passes through the connecting groove 217 and is hinged to the rear side of the rear correction wheel assembly 213. The middle part of the rear correction wheel assembly 213 is hinged to the first slider 2141.

[0031] During operation, when the output end of the cylinder 3 moves downward, it drives the first hinge block 31 and the second hinge block 32 to move downward. The second hinge block 32 is hinged to the rear side of the rear return wheel assembly 213, and the second hinge block 32 pulls down the rear side of the rear return wheel assembly 213. Since the middle part of the rear return wheel assembly 213 is hinged to the first slider 2141, the rear return wheel assembly 213 flips downward when the cylinder 3 descends, so that the rear return wheel assembly 213 can be flipped to the bottom of the conveyor belt body. When the output end of the cylinder 3 rises, the rear side of the rear return wheel assembly 213 is pushed upward, so that the rear return wheel assembly 213 flips to the top of the conveyor belt 1, which is convenient for correcting the battery cells.

[0032] In this embodiment, the left return wheel assembly 211 includes a first fixed block 2111 fixedly connected to the second slider 2151, and two first connecting shafts are arranged on the top of the first fixed block 2111 from front to back, and the first return wheel 21111 is rotatably connected to the first connecting shaft. The right return wheel assembly 212 is symmetrically arranged with the left return wheel assembly 211.

[0033] During operation, the first return wheel 21111 abuts against the battery cell, so that the battery cell will not be damaged when it moves.

[0034] In this embodiment, the rear return wheel assembly 213 includes a third hinge block 2131, the rear side of the third hinge block 2131 is hinged to the second hinge block 32, the front lower side of the third hinge block 2131 is hinged to the first slider 2141, and the front upper side of the third hinge block 2131 is fixedly connected to the second fixed block 2132, and two second connecting shafts are arranged on the second fixed block 2132 at intervals along the left and right directions, and the second return wheel 2133 is rotatably connected to the second connecting shaft.

[0035] The above-mentioned structure is set up, and the rear return wheel assembly 213 is set to include a third hinge block 2131, and the rear side of the third hinge block 2131 is hinged to the second hinge block 32, the front lower side of the third hinge block 2131 is hinged to the first sliding block, and the front upper side of the third hinge block 2131 is connected to the return wheel through the second fixed block 2132, so that when the second hinge block 32 pulls down the rear side of the third hinge block 2131, the front upper side of the third hinge block 2131 flips backward, so that the rear return wheel assembly 213 is deflected to the bottom of the conveyor belt body.

[0036] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
