[0028] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0029] Reference Figures 1 to 5 An example of the present invention provides a clamping device for a battery cell and a top bracket, comprising a supporting mechanism 1, a battery cell clamping mechanism 2, a material shifting mechanism 3 and a top bracket clamping mechanism 4.

[0030] Among them, the support mechanism 1 includes a base 11, a first support frame 12 arranged on the base 11, and a support seat 13 arranged on the first support frame 12. A positioning pin 14 is provided on the support seat 13. The support seat 13 is used to support the battery cell. The positioning pin 14 cooperates with the positioning hole in the battery cell, thereby enabling precise positioning of the battery cell.

[0031] Furthermore, the battery cell clamping mechanism 2 includes a top clamping assembly 21 and a side clamping assembly 22. The top clamping assembly 21 is used to press the battery cell onto the support seat 13, and the side clamping assembly 22 is used to clamp the two side supports on both sides of the battery cell respectively.

[0032] Functionally, the material shifting mechanism 3 is used to shift the ends of the two side supports outwards.

[0033] Furthermore, the top bracket clamping mechanism 4 is used to clamp the ends of the two side supports on both sides of the top bracket respectively. Specifically, the top bracket clamping mechanism 4 includes a second support frame 41, two first driving members 42 arranged on the second support frame 41, and two first clamping blocks 43 respectively arranged on the two first driving members 42. The second support frame 41 is arranged on one side of the first support frame 12, and the two first clamping blocks 43 are arranged opposite to each other. The two first driving members 42 respectively drive the two first clamping blocks 43 to approach or move away from each other.

[0034] During operation, the manipulator (not shown in the figure) transfers the battery cell to the support seat 13 and inserts the positioning pin 14 on the support seat 13 into the positioning hole in the battery cell. Then, the manipulator transfers the two side supports to the two sides of the battery cell respectively, and makes the ends of the two side supports extend out of the top of the battery cell. Then, the side clamping assembly 22 clamps the two side supports on both sides of the battery cell respectively, and the top clamping assembly 21 presses the battery cell onto the support seat 13. Then, the material diverting mechanism 3 pushes the ends of the two side supports outward, and the manipulator transfers the top bracket to between the ends of the two side supports. Then, the material-pickup mechanism 3 withdraws, and the two side supports lose their force of spreading, so that the ends of the two side supports are respectively attached to the two sides of the top bracket, and the assembly holes on the two side supports correspond to the clamping columns on both sides of the top bracket. Finally, the two first driving members 42 respectively drive the two first clamping blocks 43 to approach each other, and the two first clamping blocks 43 respectively clamp the ends of the two side supports on both sides of the top bracket, thereby automatically assembling the top bracket on the top of the battery cell, improving production efficiency, and ensuring that the battery cell and the top bracket are always clamped during the transplanting process.

[0035] In some preferred embodiments, the second support frame 41 is a T-shaped frame, the first driving member 42 is a telescopic cylinder, a first guide rail 44 is provided on the T-shaped frame, a first slider 45 is provided at the telescopic end of the telescopic cylinder, the first clamping block 43 is provided on the first slider 45, the first slider 45 is slidably connected to the first guide rail 44, the telescopic cylinder drives the first slider 45 to move along the length direction of the first guide rail 44, and the first slider 45 drives the first clamping block 43 to move, thereby improving the stability of the first clamping block 43 when moving.

[0036] Furthermore, the material shifting mechanism 3 is arranged on the second support frame 41, and the material shifting mechanism 3 includes two shifting rods 31, a second driving member 32 for driving the two shifting rods 31 to enter between the ends of the two side supports, and a third driving member 33 for driving the two shifting rods 31 to move closer to or away from each other.

[0037] Specifically, the second driving member 32 is a lifting cylinder, and the third driving member 33 is a finger cylinder. The lifting cylinder is installed on the second support frame 41. The finger cylinder is installed on the telescopic end of the lifting cylinder through the mounting plate 34. The two levers 31 are respectively arranged at the two output ends of the finger cylinder.

[0038] It can be understood that after the side clamping assembly 22 clamps the two side supports on both sides of the battery cell respectively, the lifting cylinder drives the two levers 31 to rise, so that the two levers 31 enter between the ends of the two side supports, and then, the finger cylinder drives the two levers 31 to move away from each other to spread the ends of the two side supports, so that there is enough space between the ends of the two side supports to accommodate the top bracket to enter. When the top bracket is placed between the ends of the two side supports, the finger cylinder drives the two levers 31 to move closer to each other, and the lifting cylinder drives the two levers 31 to descend, so that the ends of the two side supports lose their supporting force and stick to the two sides of the top bracket.

[0039] In some preferred embodiments, a jacking assembly 15 is also provided on the base 11, and the jacking assembly 15 is used to jack the support seat 13. Specifically, the jacking assembly 15 includes a jacking plate 151 and a fourth driving member 152 for driving the jacking plate 151 to rise or fall. The first support frame 12 is connected to the jacking plate 151, and the second support frame 41 is arranged on the jacking plate 151.

[0040] It can be understood that when the manipulator grabs the battery cell and transfers it to the top of the support seat 13, the fourth driving member 152 drives the lifting plate 151 to rise, and the lifting plate 151 drives the support seat 13 to rise. Then, the manipulator releases the clamping jaws to place the battery cell on the support seat 13. Finally, the fourth driving member 152 drives the lifting plate 151 to descend, and the lifting plate 151 drives the support seat 13 and the battery cell to descend. In this way, the clamping jaws of the manipulator can be prevented from interfering with other parts of the equipment when the clamping jaws are released, thereby ensuring the normal operation of the equipment.

[0041] It should be noted that the fourth driving member 152 can be a cylinder, or a linear module or other power device that can drive the lifting plate 151 to move up and down.

[0042] Furthermore, the first support frame 12 includes a support plate 121 and several vertically arranged support columns 122. The lifting plate 151 is provided with several guide sleeves 153, and the several guide sleeves 153 are respectively sleeved on the outer periphery of the several support columns 122. The support plate 121 is located directly above the support column 122. The support plate 121 and the several support columns 122 are separately arranged. The lifting plate 151 is connected to the support plate 121, and the support seat 13 is arranged on the support plate 121.

[0043] It can be understood that when the fourth driving member 152 drives the lifting plate 151 to rise, the guide sleeve 153 on the lifting plate 151 slides along the length direction of the support column 122, and the lifting plate 151 drives the support plate 121 and the support seat 13 to rise together, thereby improving the stability of the support seat 13 during movement; when the fourth driving member 152 drives the lifting plate 151 to descend, the lifting plate 151 drives the support plate 121 to descend until the bottom of the support plate 121 abuts against the tops of several support columns 122, so that several support columns 122 support the support plate 121, thereby reducing the load of the fourth driving member 152 and improving the service life of the fourth driving member 152.

[0044] Furthermore, a plurality of buffers 154 are connected between the lifting plate 151 and the support plate 121 , which can buffer the impact on the lifting plate 151 when the battery cell is placed on the support seat 13 , thereby increasing the service life of the fourth driving member 152 .

[0045] In some preferred embodiments, the side clamping assembly 22 includes a fixed block 221, a second clamping block 222 and a fifth driving member 223 for driving the second clamping block 222 close to or away from the fixed block 221, the fixed block 221 is arranged on one side of the support seat 13, and the fifth driving member 223 is arranged on the support plate 121.

[0046] Furthermore, a second guide rail 224 is provided on the support plate 121, a second slider 225 is slidably connected to the second guide rail 224, a second clamping block 222 is provided on one side of the second slider 225, a fifth driving member 223 is connected to the second slider 225, and a top clamping assembly 21 is installed on the second slider 225, thereby improving the stability of the second clamping block 222 during movement.

[0047] Specifically, the fifth driving member 223 is a cylinder, which is installed at the bottom of the support plate 121. The telescopic end of the cylinder is connected to the second slider 225 through a connecting plate. The support plate 121 is provided with an air avoidance groove for accommodating the movement of the connecting plate, thereby making the structure compact.

[0048] Furthermore, the top clamping assembly 21 includes a third clamping block 211 and a sixth driving member 212 for driving the third clamping block 211 to rise or fall. The sixth driving member 212 is mounted on the second sliding block 225 .

[0049] It can be understood that the fifth driving member 223 drives the second slider 225 to move along the length direction of the second guide rail 224, and the second slider 225 drives the second clamping block 222 to approach the fixed block 221, clamping the two side supports on both sides of the battery cell respectively. At the same time, the second slider 225 also drives the top clamping assembly 21 to move as a whole, so that the third clamping block 211 is located directly above the battery cell. Then, the sixth driving member 212 drives the third clamping block 211 to descend, and the third clamping block 211 presses the battery cell onto the support seat 13, thereby ensuring the firmness of the clamping of the battery cell and preventing the battery cell from loosening during transplantation.

[0050] It should be noted that the sixth driving member 212 can be a cylinder, or a linear module or other power device that can drive the third clamping block 211 to move up and down.

[0051] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments.

These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
