Description

Technical Field

[0001] The present invention relates to the field of batteries, and particularly to a conveying and clamping mechanism based on precise positioning of battery cells. Background Art

[0002] "Lithium batteries" are a type of battery with a lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. The lithium metal battery was first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M. S. Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high requirements for the environment. Therefore, lithium batteries have not been applied for a long time. With the development of science and technology, lithium batteries have now become the mainstream.

[0003] During the production process of existing lithium battery cells, the cells need to be conveyed between the settings corresponding to each process. However, the existing cell conveying equipment has low transmission efficiency, the transmission lines are mostly linearly distributed, occupying a large space, and the existing cell conveying settings lack a corresponding clamping structure for the cells, making the cells prone to skew and fall during transportation, affecting the clamping of the cells in the next process. Summary of the Invention

[0004] Based on this, it is necessary to provide a conveying and clamping mechanism based on precise positioning of battery cells, including a frame. A rotating bracket is rotatably arranged on the frame. The rotating bracket is in a disc shape. A plurality of sleeves are fixedly arranged at the edge of the rotating bracket. The sleeves are in a hollow cylindrical shape. A support rod is arranged inside the sleeve. The lower end of the support rod is connected to the frame through a lifting mechanism, and the lifting mechanism can drive the support rod to move up and down inside the sleeve.

[0005] During the conveying process of the battery cells, the cells are placed into the sleeves. The support rods inside the sleeves are used to support the cells to prevent the cells from falling out of the sleeves. The inner diameter of the sleeves is slightly larger than the diameter of the cells, which can prevent the cells from skewing during transportation. Moreover, the conveying path of the cells is circular, making the structure of the present invention more compact and occupying less space. In addition, the lifting mechanism can drive the support rods inside the sleeves to move up and down inside the sleeves, so as to eject the cells from the sleeves, facilitating the next process to take away the cells. At the same time, when the cells are placed in the upper process, the cells can slowly descend as the support rods descend, rather than directly falling into the sleeves, causing damage to the sleeves or the cells.

[0006] Preferably, a clamping opening is provided on the sleeve, and a clamping device is provided on the outer side wall of the sleeve, the clamping device includes a base fixedly provided on the sleeve, a clamping arm hinged to the base, the middle part of the clamping part is hinged to the base, two mutually parallel connecting arms are provided at the upper end of the clamping arm, a roller is rotatably provided between the two connecting arms, the roller is located in the clamping opening, and the lower end of the clamping arm is connected to the outer wall of the sleeve through a spring.

[0007] The spring at the upper end of the clamping arm has a thrust on the lower end of the clamping arm, pushing it away from the sleeve. Since the middle part of the clamping arm is hinged to the base, the roller at the upper end of the clamping part will pass through the clamping opening and be pressed into the sleeve, pressing the battery cell tightly in the sleeve to prevent the battery cell from shaking in the sleeve. At the same time, the rotatable roller will not affect the placement and removal of the battery cell. In addition, when placing the battery cell into the sleeve, the line segment of the clamping arm can be pressed to make the roller disengage from the sleeve, making it easier to place the battery cell.

[0008] Furthermore, the width of the roller is smaller than the width of the clamping opening, and the two support arms respectively abut against the edges of the clamping opening.

[0009] The support arm abuts against the edge of the clamping opening to prevent the roller from being excessively pressed into the sleeve and causing damage to the battery cell.

[0010] Preferably, the lifting mechanism includes an annular guide rail arranged at the bottom of the frame, the annular guide rail is arranged corresponding to the edge of the rotating bracket, the annular guide rail includes a high end, a low end and a transition portion connecting the high end and the bottom end, the transition portion gradually increases in height from the bottom end to the high end, the lower end of the support rod is connected to a support block, the inner side of the support block is provided with a sliding portion, and the sliding portion abuts against the upper surface of the annular guide rail.

[0011] When the annular bracket rotates, the sliding part on the support block slides along the annular guide rail. When the sliding part is located at the bottom end of the annular guide rail, the support rod in the sleeve is located at the lowest point. As the annular bracket rotates, the sliding part slides from the low end of the annular guide rail to the high end of the annular guide rail, and the height of the support rod in the sleeve gradually increases until it reaches the highest point. Then the sliding part slides from the high end to the low end, and so on. Therefore, the battery cell can be placed in the sleeve when the support rod is at the highest point. The battery cell descends with the support rod. After the battery cell reaches the lowest point, the relevant equipment performs corresponding operations on it. After the operation, the sliding part slides to the high end of the annular guide rail again to push the battery cell out of the sleeve, and then the equipment of the next process takes away the battery cell.

[0012] Furthermore, a guide rod is vertically arranged on the support block, and a guide hole is arranged on the rotating bracket corresponding to the guide rod. The guide rod passes through the guide hole and cooperates with the guide hole.

[0013] The guide rod and the guide hole cooperate with each other to ensure the stability of the support block during the ascending and descending processes, thereby ensuring that the support rod will not tilt and contact the inner wall of the sleeve during the ascending and descending processes, and further ensuring that the support rod can ascend and descend smoothly.

[0014] Further, the sliding part is a pulley rotatably arranged on the support block.

[0015] The pulley can slide better on the annular guide rail.

[0016] Preferably, a manipulator is further arranged on the frame, and the manipulator is located above the high end.

[0017] The manipulator is used to place the battery cell into the sleeve located above the high end of the annular guide rail, and the manipulator is a prior art.

[0018] The principle and effect of the present invention will be further described below in combination with the above technical solutions:

[0019] During the transmission process of the battery cell in the present invention, the battery cell is placed into the sleeve, and the support rod in the sleeve is used to support the battery cell to prevent the battery cell from falling out of the sleeve. The inner diameter of the sleeve is slightly larger than the diameter of the battery cell, which can avoid the battery cell from tilting during transportation, and the transmission path of the battery cell is circular, making the structure of the present invention more compact and occupying less space; in addition, the lifting mechanism can drive the support rod in the sleeve to move up and down in the sleeve, so as to realize ejecting the battery cell from the sleeve, facilitating the removal of the battery cell in the next process. At the same time, when the battery cell is placed in the upper moving process, the battery cell can slowly descend as the support rod descends, rather than directly falling into the sleeve, causing damage to the battery cell sleeve or the battery cell.

Detailed Embodiment

[0024] In order to facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0025] like Figure 1-2 A conveying and clamping mechanism based on precise positioning of battery cells includes a frame 1, on which a rotating bracket is rotatably provided, the rotating bracket is in the shape of a disc, and a plurality of sleeves 12 are fixedly provided on the edge of the rotating bracket, the sleeve 12 is in the shape of a hollow cylinder, a support rod 13 is provided in the sleeve 12, and the lower end of the support rod 13 is connected to the frame 1 through a lifting mechanism, and the lifting mechanism can drive the support rod 13 to move up and down in the sleeve 12.

[0026] During the transportation of the battery cell 2, the battery cell 2 is placed in the sleeve 12. The support rod 13 in the sleeve 12 is used to support the battery cell 2 to prevent the battery cell 2 from falling out of the sleeve 12. The inner diameter of the sleeve 12 is slightly larger than the diameter of the battery cell 2, which can prevent the battery cell 2 from tilting during transportation. The transportation path of the battery cell 2 is annular, which makes the structure of the present invention more compact and occupies less space. In addition, the lifting mechanism can drive the support rod 13 in the sleeve 12 to move up and down in the sleeve 12, so as to push the battery cell 2 out of the sleeve 12, making it convenient for the next process to take out the battery cell 2. At the same time, when the battery cell 2 is placed in the upward process, the battery cell 2 can slowly descend with the descent of the support rod 13, and will not directly fall into the sleeve 12, causing damage to the battery cell 2, the sleeve 12 or the battery cell 2.

[0027] In one embodiment, a clamping opening 121 is provided on the sleeve 12, and a clamping device is provided on the outer wall of the sleeve 12, the clamping device includes a base 1223 fixedly provided on the sleeve 12, a clamping arm 1221 hinged to the base 1223, the middle part of the clamping part is hinged to the base 1223, two connecting arms parallel to each other are provided at the upper end of the clamping arm 1221, a roller 1222 is rotatably provided between the two connecting arms, the roller 1222 is located in the clamping opening 121, and the lower end of the clamping arm 1221 is connected to the outer wall of the sleeve 12 through a spring.

[0028] The spring at the upper end of the clamping arm 1221 has a thrust on the lower end of the clamping arm 1221, pushing it away from the sleeve 12. Since the middle part of the clamping arm 1221 is hinged to the base 1223, the roller 1222 at the upper end of the clamping part will pass through the clamping opening 121 and be pressed into the sleeve 12, pressing the battery cell 2 tightly in the sleeve 12 to prevent the battery cell 2 from shaking in the sleeve 12. At the same time, the rotatable roller will not affect the placement and removal of the battery cell 2. In addition, when placing the battery cell 2 into the sleeve 12, the line segment of the clamping arm 1221 can be pressed to disengage the roller 1222 from the sleeve 12, making it easier to place the battery cell 2.

[0029] In one embodiment, the width of the roller 1222 is smaller than the width of the clamping opening 121, and the two support arms 1224 respectively abut against the edges of the clamping opening 121.

[0030] The support arms 1224 abutting against the edges of the clamping opening 121 can prevent the roller 1222 from being overly pressed into the sleeve 12, thus causing damage to the battery cell 2.

[0031] In one embodiment, the lifting mechanism includes an annular guide rail 15 provided at the bottom of the frame 1. The annular guide rail 15 is provided corresponding to the edge of the rotating bracket 11. The annular guide rail 15 includes a high end 151, a low end 152, and a transition portion connecting the high end 151 and the low end. The height of the transition portion gradually increases from the low end to the high end 151. The lower end of the support rod 13 is connected with a support block 141. A sliding portion 142 is provided on the inner side of the support block 141, and the sliding portion 142 abuts against the upper surface of the annular guide rail 15.

[0032] When the annular bracket rotates, the sliding portion 142 on the support block 141 slides along the annular guide rail 15. When the sliding portion 142 is located at the low end of the annular guide rail 15, the support rod 13 in the sleeve 12 is at the lowest position. As the annular bracket rotates, the sliding portion 142 slides from the low end 152 of the annular guide rail 15 to the high end 151 of the annular guide rail 15, and the height of the support rod 13 in the sleeve 12 gradually increases until it reaches the highest position. Then the sliding portion 142 slides from the high end 151 to the low end 152, and so on. Therefore, the battery cell 2 can be placed into the sleeve 12 when the support rod 13 is at the highest position. The battery cell 2 descends along with the support rod 13. After the battery cell 2 reaches the lowest point, the relevant equipment performs corresponding operations on it. After the operation, the sliding portion 142 slides to the high end 151 of the annular guide rail 15, pushing the battery cell 2 out of the sleeve 12, and then the equipment of the next process takes away the battery cell 2.

[0033] In one embodiment, a guide rod 143 is vertically provided on the support block 141. The rotating bracket is provided with a guide hole 144 corresponding to the guide rod 143. The guide rod 143 passes through the guide hole 144 and is matched with the guide hole 144.

[0034] The mutual cooperation between the guide rod 143 and the guide hole 144 ensures the stability of the support block 141 during the ascending and descending processes, thereby ensuring that the support rod 13 will not be skewed and contact the inner wall of the sleeve 12 during the ascending and descending processes, and further ensuring that the support rod 13 can smoothly ascend and descend.

[0035] In one embodiment, the sliding portion 142 is a pulley rotatably provided on the support block 141.

[0036] The pulley can slide better on the annular guide rail 15.

[0037] In one of the embodiments, a manipulator is further provided on the rack 1, and the manipulator is located above the high end 151.

[0038] The manipulator is used to place the battery cell 2 into the sleeve 12 located above the high end 151 of the annular guide rail 15, and the manipulator is a prior art.

[0039] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
