When aligning the battery cells, it is often necessary to drive in at least two directions to complete the action of pushing the battery cells so that the battery cells move to the target position. In the prior art, at least two driving components are usually used to complete the action in two directions respectively. First, the blocking column is inserted between the battery cells through the lifting mechanism, and then the blocking column is moved horizontally through the translation mechanism so that the blocking column pushes the edge of the battery cell. This battery cell alignment mechanism has a complex structure, high cost, and occupies a large space. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0020] Reference Figure 1As shown, the present application proposes a correction mechanism, including a swing cylinder 2, an L-shaped lever 3, a sliding support 4, a correction component 1 and a base plate 5, wherein: the correction component 1 is vertically slidably connected to the side wall of the sliding support 4 through a first guide rail 8, the bottom of the sliding support 4 is horizontally slidably connected to the base plate 5 through a second guide rail 7, the middle part of the L-shaped lever 3 is rotatably connected to one side of the sliding support 4 through a rotating shaft 31, one side of the sliding support 4 is provided with an opening adapted to the rotation of the L-shaped lever 3, and the two side walls opposite to the opening are used to fix the two ends of the rotating shaft 31, the first end of the L-shaped lever 3 is connected to the bottom of the correction component 1, and the second end thereof is hinged to the piston rod end of the swing cylinder 2, the tail of the swing cylinder 2 is hinged to the base plate 5, and a first tension spring 6 acting in the opposite direction to the pulling direction of the swing cylinder 2 is also provided between the sliding support 4 and the base plate 5, the swing cylinder 2 drives one end of the L-shaped lever 3 to rotate and translate in sequence, so that the correction component 1 is lifted and the sliding support 4 moves horizontally.
[0021] Specifically, in the initial state of the correction mechanism, the piston rod of the swing cylinder 2 extends out of the cylinder body, the first end of the L-shaped lever 3 and the correction component 1 movably connected to the first end of the L-shaped lever 3 are both in a low position. When the battery cell is corrected, the piston rod of the swing cylinder 2 pulls the second end of the L-shaped lever 3 to rotate. At the same time, the first end of the L-shaped lever 3 moves upward to lift the correction component 1 to a high position, so that the correction component 1 partially extends into the gap between adjacent battery cells. When the swing cylinder 2 connects the second end of the L-shaped lever 3 with the rotating shaft 31 When it is pulled to be in line with the piston rod of the swing cylinder 2, the L-shaped lever 3 no longer rotates, and the swing cylinder 2 continues to pull the second end of the L-shaped lever 3. At this time, the swing cylinder 2 will overcome the pulling force of the first tension spring 6 and continue to pull the L-shaped lever 3, so that the first tension spring 6 is stretched, and the L-shaped lever 3 no longer rotates, but follows the sliding support 4 to move horizontally along the second guide rail 7, so that part of the correction component 1 is close to the edge of one side of the battery cell and pushes the battery cell to move horizontally, so as to push the battery cell to the target position and complete the correction of the battery cell.
[0022] It should be noted that the elastic force of the first tension spring 6 is greater than the overall gravity of the correcting component 1. Since the elastic force of the first tension spring 6 is greater than the force acting on the first end of the L-shaped lever 3 when the correcting component 1 falls downward, after the correcting is completed, when the piston rod of the swing cylinder 2 is extended, under the tension of the first tension spring 6, the sliding support 4 will first move following the amount of extension of the piston rod of the swing cylinder 2, so that the correcting component 1 is withdrawn from the edge of the battery cell. After the sliding support 4 is in place, the piston rod of the swing cylinder 2 continues to extend, so that the L-shaped lever 3 rotates around the rotating shaft 31, and the first end of the L-shaped lever 3 rotates to a low position, lowering the correcting component 1 below the lower surface of the battery cell, and moving the correcting component 1 to its initial position.
[0023] Compared with the prior art, the present application realizes the sequential actions of lifting and translating the correction component 1 only through the driving extension and retraction of a power cylinder and the tension of the first tension spring 6, so as to reduce a set of driving mechanisms and save the manufacturing cost of the correction mechanism. It has a simple structure and occupies a small space, so as to save the use space of the equipment.
[0024] It should be noted that the at least one battery cell corresponding to the correction component 1 can also correspond to multiple battery cells at the same time, and correct multiple battery cells at the same time, thereby reducing the time for conveying and correcting the battery cells, so as to improve the production efficiency of the battery cells.
[0025] In some embodiments, the correction component 1 includes a mounting plate 10 and a support plate 11 fixed to the bottom of the mounting plate 10, the bottom end of the support plate 11 abuts against the first end of the L-shaped lever 3, and the top surface of the mounting plate 10 is also detachably mounted with at least two blocking columns 12, at least two of the blocking columns 12 are arranged in a horizontal plane perpendicular to the moving direction of the second guide rail, that is, at least two blocking columns 12 are linearly arranged on one side of the battery cell for contacting one side of the battery cell, and under the action of the swing cylinder 2, the blocking column 12 can be raised and lowered in the gap between the two battery cells, and the battery cell is pushed to the target position.
[0026] In some embodiments, the blocking column 12 includes a fixed shaft 121 whose axial end is fixed to the top of the mounting plate 10, and a return sleeve 122 inserted into the fixed shaft 121. The top of the fixed shaft 121 is also sleeved with a retaining ring 123 for limiting the axial position of the return sleeve 122. The return sleeve 122 is rotatably mounted on the fixed shaft 121, so that when the blocking column 12 contacts the edge of the battery cell and pushes the battery cell, the edge of the battery cell and the blocking column 12 roll and rub, thereby reducing the friction between the edge of the battery cell and the blocking column 12, and reducing the risk of edge fragmentation and cracks in the battery cell.
[0027] In some embodiments, the bottom end of the support plate 11 abuts against the first end of the L-shaped lever 3, including: a bearing 32 is installed on the first end of the L-shaped lever 3, and the bottom end of the support plate 11 is pressed against the outer ring of the bearing 32, and the outer ring rotates around the center of the bearing 32 while rotating around the rotating shaft 31 as the first end of the L-shaped lever 3 rotates. When the swing cylinder 2 pulls the L-shaped lever 3, the first end of the L-shaped lever 3 will slide relative to the bottom of the support plate 11. The purpose of the abutment of the bearing 32 is to reduce the friction between the first end of the L-shaped lever 3 and the bottom of the support plate 11, so that the L-shaped lever 3 rotates more smoothly and the output of the swing cylinder 2 is reduced.
[0028] It should be noted that the connection between the bottom end of the support plate 11 and the L-shaped lever 3 is not limited to being connected through the bearing 32. The first end of the L-shaped lever 3 can also be directly abutted against the bottom of the support plate 11. The tip of the first end of the L-shaped lever 3 is an arc surface, and the arc surface contacts the bottom of the support plate 11 to accommodate the rotation of the first end of the L-shaped lever 3 relative to the bottom of the support plate 11.
[0029] Preferably, a second tension spring 9 is further provided between the correction component 1 and the sliding support 4, and the extension direction of the second tension spring 9 is consistent with the vertical sliding direction of the correction component 1. It should be noted that the elastic force of the second tension spring 9 is smaller than the elastic force of the first tension spring 6. The second tension spring 9 enables the correction component 1 to always have a downward force, so that the bottom end of the support plate 11 is always against the outer ring of the bearing 32 at the first end of the L-shaped lever 3. When the swing cylinder 2 drives the L-shaped lever 3 to rotate and lift the correction component 1, it is necessary to overcome the tension of the second tension spring 9 to lift the correction component 1. When resetting after correction, since the elastic force of the first tension spring 6 is greater than the elastic force of the second tension spring 9, the sliding support 4 will first translate relative to the support plate 11. After the first tension spring 6 is reset, the L-shaped lever 3 rotates to make the correction component 1 descend to a low position.
[0030] The present application also provides a battery cell transmission device, including two parallel transmission belts 200 and any one of the above-mentioned correction mechanisms, the base plate 5 also includes a vertically installed upright plate 51, the correction mechanism is installed between the two sets of transmission belts 200 through the upright plate 51, the two sets of transmission belts 200 are used to jointly receive the two ends of the battery cell and transmit the battery cell to the top of the correction mechanism, the gap between the battery cells is aligned with the top of the blocking column 12, and then the correction mechanism is used to correct the battery cells on the transmission belt 200.
[0031] When a conveyor belt is usually used to transport battery cells, the conveyor belt and the driving wheel are prone to relative slippage, resulting in inaccurate transmission position of the battery cells, which reduces the fault tolerance of the battery cell conveyor belt 200 and affects the welding quality of the battery string. To ensure the welding quality of the battery string, before grabbing the battery cells and welding the welding ribbons, the battery cells need to be aligned to the target position during the conveying process. The aligned battery cells are used to weld the battery string.
[0032] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
[0033] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
