However, since the size matching clearance between the positive electrode post of the shell and the positive electrode post terminal of the battery cell is required to be zero tolerance, when the conventional battery cell is put into the shell, there is a deviation in the welding between the positive terminal of the battery cell and the positive electrode post, and there is an assembly deviation between the battery cell and the shell. As a result, the battery terminal is blocked by the positive electrode post area when entering the shell, and the positive terminal cannot be accurately inserted into the shell.

[0027] Reference below Figure 1 A battery shell insertion device according to an embodiment of the utility model is described.

[0028] According to the utility model, the battery shell introduction device 1 includes a bracket 11, a battery cell fixing seat 12, a clamping part 13, a moving part and a pressing device, the battery cell fixing seat 12 is arranged on the bracket 11 and is formed with an accommodating groove for accommodating the battery cell 121; the clamping part 13 is arranged on the bracket 11, the clamping part 13 is opposite to the accommodating groove in the height direction and is suitable for clamping the shell 131; the moving part is movably arranged on the bracket 11 and the guiding device 143 is arranged on the moving part, the moving part is suitable for driving the guiding device 143 to pass through the terminal mounting hole of the shell 131 and push the clamping part 13 and the battery cell fixing seat 12 to be positioned; the pressing device is arranged on the bracket 11 and is suitable for pressing the battery cell 121 into the shell 131 after the clamping part 13 and the battery cell fixing seat 12 are positioned.

The battery cell 121 is placed in the receiving groove, and the positive terminal of the battery cell 121 is arranged toward the shell 131. The shell 131 is arranged on the clamping part 13, and an open mouth is formed on the shell 131. The open mouth is arranged toward the battery cell 121. A terminal mounting hole is formed on the shell 131, and the terminal mounting hole is arranged at one end of the shell 131 away from the battery cell 121. The battery cell 121 can enter the shell 131 through the open mouth and align the positive terminal of the battery cell 121 with the terminal mounting hole. A receiving device 143 is arranged on the moving part, and the receiving device 143 moves in a first direction, extends from the terminal mounting hole into the shell 131 and extends toward the terminal of the battery cell 121. 43 can push the clamping part 13 to move toward the battery cell fixing seat 12 to position the clamping part 13 and the battery cell fixing seat 12, thereby positioning the connecting device 143 and the positive terminal of the battery cell 121. After the connecting device 143 stops at the center of the positive terminal of the battery cell 121, the terminal mounting hole of the shell 131 is directly opposite to the positive terminal of the battery cell 121 in the first direction. At this time, the battery cell 121 can be pushed toward the shell 131 by the pressing device, and the battery cell 121 is pushed into the shell 131 from the open mouth of the shell 131. During this process, the connecting device 143 is always in contact with the positive terminal of the battery cell 121 to ensure that the positive terminal is always directly opposite to the terminal mounting hole of the shell 131. After the pressing device pushes the battery cell 121 into the shell 131, the positive terminal is accurately installed in the terminal mounting hole.

[0030] According to the battery shell guiding device 1 of the utility model, a guiding device 143 is arranged on the moving part, and the guiding device 143 is driven to move by the moving part. The guiding device 143 extends into the shell 131 from the terminal mounting hole of the shell 131 and moves toward the battery cell 121 until the guiding device 143 stops contacting with the positive terminal of the battery cell 121. The guiding device 143 positions the positive terminal of the battery cell 121 and the terminal mounting hole of the shell 131 in the first direction. After the positioning is completed, the pressing device pushes the battery cell 121 to move toward the shell 131 and pushes the battery cell 121 into the shell 131. During this process, the guiding device 143 always stops contacting with the battery cell 121 and ensures that the positive terminal of the battery cell 121 and the terminal mounting hole are accurately positioned, so as to ensure that the battery cell 121 is accurately inserted into the shell, avoid obstruction when the positive terminal of the battery cell 121 is inserted into the shell, and improve the shell insertion yield of the battery cell 121.

[0031] According to some embodiments of the present invention, the moving portion is suitable for driving the guiding device 143 to move in the first direction to approach the battery cell holder 12 , and aligning the guiding device 143 with the terminal of the battery cell 121 to position the housing 131 , the guiding device 143 and the battery cell holder 12 .

[0032] Specifically, after the battery cell 121 is installed on the battery cell fixing seat 12 and the shell 131 is installed on the clamping portion 13, the battery cell 121 and the shell 131 are facing each other in the first direction. At this time, the guiding device 143 is facing each other with the terminal mounting hole of the shell 131 in the first direction, and the moving portion drives the guiding device 143 to move toward the shell 131 in the first direction and extend from the terminal mounting hole into the shell 131 until the guiding device 143 moves toward the battery cell fixing seat 12 and stops with the positive terminal of the battery cell 121, thereby ensuring that the positive terminal of the battery cell 121 is aligned with the shell The terminal mounting hole of 131 is directly opposite. After the shell 131, the guiding device 143 and the battery cell fixing seat 12 are positioned by the guiding device 143, the pressing device pushes the battery cell 121 into the shell 131. During this process, the positive terminal of the battery cell 121 always stops with the guiding device 143 and the guiding device 143 is gradually pushed out of the shell 131 from the terminal mounting hole. The guiding device 143 keeps abutting against the positive terminal of the battery cell 121, ensuring that the positive terminal of the battery cell 121 falls into the terminal mounting hole without deviation, ensuring that the battery cell 121 is accurately installed into the shell.

[0033] According to some embodiments of the present invention, the moving portion and the pressing device are disposed on two sides of the battery cell fixing seat 12 that are away from each other.

[0034] like Figure 1As shown, the pressing device is arranged above the battery cell fixing seat 12 in the first direction, the moving part is arranged below the battery cell fixing seat 12 in the first direction, the terminal mounting hole of the shell 131 is arranged on the side facing the moving part, the moving part drives the guiding device 143 to extend into the shell 131 from the terminal mounting hole of the shell 131 and drives the shell 131 to move toward the moving seat of the battery cell 121 until the guiding device 143 stops contacting with the positive terminal of the battery cell 121, completing the positioning of the shell 131 and the battery cell 121, the moving part shortens the distance between the shell 131 and the battery cell 121, making it convenient for the pressing device to push the battery cell 121 into the shell 131, which is beneficial to ensure that the battery cell 121 is accurately inserted into the shell.

[0035] According to some embodiments of the utility model, the moving part includes a first driving device 141 and a moving bracket 142, the first driving device 141 is arranged on the bracket and has a driving end that can move along a first direction; the moving bracket 142 is connected to the driving end, the moving bracket 142 and the clamping part 13 are arranged opposite each other in the first direction and a guiding device 143 is arranged on the moving bracket 142.

[0036] Specifically, the first driving device 141 drives the movable bracket 142 to move through the driving end, and a guiding device 143 is arranged on the movable bracket 142. The guiding device 143 can be a guiding rod, one end of which is fixed to the movable bracket 142, and the other end of the guiding rod passes through the movable bracket 142 and can move relative to the movable bracket 142. The movable bracket 142 is directly opposite to the clamping portion 13 in the first direction. The first driving device 141 drives the movable bracket 142 to move, thereby driving the guiding rod to extend from the terminal mounting hole into the shell 131 and move toward the battery cell 121. The first driving device 141 drives the movable bracket 142 to move in the first direction, thereby ensuring that the guiding device 143 can move toward the battery cell 121 in the first direction, avoiding deviation in the movement direction of the guiding device 143, and ensuring stable movement of the guiding rod.

[0037] According to some embodiments of the utility model, the first driving device 141 includes a cylinder body and a piston. A accommodating chamber for accommodating a pressure medium is formed in the cylinder body. The piston is movably arranged in the accommodating chamber, and a driving end is arranged on the piston. The first driving device 141 drives the piston to move by changing the pressure in the accommodating chamber, thereby driving the driving end to move. The first driving device 141 has a simple structure and is more convenient to drive by power.

[0038] According to some embodiments of the present invention, a sliding track 132 extending in a first direction is disposed on the bracket, and the clamping portion 13 cooperates with the sliding track 132 to move in the first direction.

[0039] like Figure 1As shown, when the guiding device 143 extends into the shell 131 and moves toward the battery cell 121, the guiding device 143 drives the shell 131 to move toward the battery cell 121 by pushing the clamping part 13 to move on the sliding rail 132. The clamping part 13 cooperates with the sliding rail 132, and the movement of the shell 131 is more stable, avoiding shaking and deviation of the shell 131 during the movement, thereby ensuring the accurate positioning of the shell 131 and the battery cell 121.

[0040] According to some embodiments of the present invention, the sliding rails 132 are constructed to be spaced apart from each other and arranged in parallel. The multiple sliding rails 132 cooperate with the clamping part 13 to jointly support the movement of the clamping part 13, so that the movement of the clamping part 13 is more stable and the movement of the shell 131 is more stable.

[0041] According to some embodiments of the present invention, a stopper 1431 suitable for cooperating with the movable bracket 142 is formed on the radial outer periphery of the guiding device 143 , and the stopper 1431 is suitable for driving the movable bracket 142 to move after the guiding device 143 cooperates with the shell 131 .

[0042] Specifically, a plurality of stop portions 1431 are formed on the radial periphery of the guiding device 143. As the guiding device 143 extends from the terminal mounting hole into the shell 131 and continues to move toward the battery cell 121, the stop portions 1431 abut against the bottom of the movable bracket 142. The first driving device 141 continues to push the guiding device 143 to move and drives the movable bracket 142 to move via the stop portions 1431, pushing the shell 131 toward the battery cell 121, shortening the distance between the battery cell 121 and the shell 131, and facilitating the battery cell 121 to enter the shell.

[0043] According to some embodiments of the present invention, the battery cell holder 12 includes a plurality of clamping jaws 122 , which are movably disposed on the bracket. The clamping jaws 122 can selectively move closer to or farther from each other to clamp or release the battery cell 121 .

[0044] Specifically, a plurality of clamps 122 are arranged on the battery cell fixing seat 12, and the positive terminal of the battery cell 121 is arranged toward the supporting portion. The plurality of clamps 122 are close to each other and clamped at the center position of the battery cell 121, and the battery cell 121 is sent into the accommodating groove of the battery cell fixing seat 12. When the guiding device 143 pushes the shell 131 toward the battery cell 121 until the guiding device 143 and the positive terminal of the battery cell 121 stop, after the battery cell 121 and the shell 131 are positioned, the plurality of clamps 122 move away from each other and release the battery cell 121, so that the pressing device can push the battery cell 121 into the shell 131.

[0045] According to some embodiments of the utility model, the pressing device includes a second driving device 151 and a pressing head 152. The second driving device 151 is arranged on the side of the battery cell fixing seat 12 away from the clamping portion 13 and has an output end that can be selectively moved toward the battery cell fixing seat 12; the pressing head 152 is connected to the output end and is suitable for stopping with the battery cell 121.

[0046] Specifically, after the guiding device 143 stops contacting the positive terminal of the battery cell 121, the battery cell 121 and the shell 131 are positioned, and the positive terminal of the battery cell 121, the guiding device 143 and the terminal mounting hole of the shell 131 are in a concentric position. At this time, the pressing device drives the pressure head 152 to move toward the battery cell 121 by driving the output end. After the pressure head 152 stops contacting the battery cell 121, the battery cell 121 continues to be pushed by the output end to move, so as to push the battery cell 121 into the shell 131. During this process, one end of the battery cell 121 stops contacting the pressure head 152, and the other end of the battery cell 121 stops contacting the guiding device 143, so that the positive terminal is always kept facing the terminal mounting hole to avoid deviation of the battery cell 121 when entering the shell.
