DETAILED DESCRIPTION
[0025] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.
[0026] See also Figure 1-2 As shown, the utility model provides a lithium battery bundling tool, including a bottom plate 1, a first baffle plate 2, a second baffle plate 3, a top plate 4, a top plate push rod 5, a linkage structure 6 and a drive assembly 7, the bottom plate 1 is fixedly mounted with a first baffle plate 2 and a second baffle plate 3 which are perpendicular to each other, the lithium battery cells 8 are arranged side by side on the bottom plate 1, and the rear side and the left side of the lithium battery cells 8 are respectively in contact with the first baffle plate 2 and the second baffle plate 3, the bottom plate 1 is also mounted with a drive assembly 7, the output end of the drive assembly 7 is driven and connected to the top plate push rod 5 through the linkage structure 6, the top plate 4 is fixedly mounted on the top plate push rod 5, and the top plate 4 is in contact with the right side of the lithium battery cells 8.
[0027] Furthermore, in order to enable the driving component 7 to drive the top plate push rod 5 to move, the driving component 7 includes a cylinder mounting seat 71, a driving cylinder 72 and a second push rod 73. The cylinder mounting seat 71 is fixedly mounted on the base plate 1, and the front end of the driving cylinder 72 is hingedly connected to the cylinder mounting seat 71. The output end of the driving cylinder 72 is connected to the second push rod 73, and the second push rod 73 is connected to the linkage structure 6.
[0028] Furthermore, in order to control the push-pull effect of the driving cylinder 72 , a cylinder control switch 11 is also installed on the base plate 1 , and the cylinder control switch 11 is pneumatically connected to the driving cylinder 72 .
[0029] Furthermore, a control system is installed on the bottom plate 1, and a pressure sensor 41 is installed on the side of the top plate 4 facing the lithium battery cell 8. The control system is electrically connected to the pressure sensor 41 and the cylinder control switch 11. The tooling can accurately control the stacking force and achieve uniform distribution of the battery cells through the data detected by the pressure sensor 41, which can effectively prevent the battery cells from being deformed or damaged during the stacking process. This helps to ensure the quality and performance of the battery cells and extend the service life of the battery system.
[0030] Furthermore, in order to realize that the linkage structure 6 can connect the driving cylinder 72 and the top plate push rod 5, the linkage structure 6 includes a fixed mounting plate 61, a swinging member 62 and a connecting fastener 63. The fixed mounting plate 61 is fixed on the bottom plate 1. A triangular swinging member 62 is hinged on the fixed mounting plate 61. The other end of the swinging member 62 away from the hinge point is connected to the second push rod 73. The middle position of the swinging member 62 is also hingedly installed with a connecting fastener 63. The other end of the connecting fastener 63 away from the swinging member 62 is connected to the top plate push rod 5. When the second push rod 73 of the driving cylinder 72 telescopes forward and backward, it drives the swinging member 62 to rotate relative to the fixed mounting plate 61, thereby driving the connecting fastener 63 and the top plate push rod 5 to move forward and backward, clamping or releasing the lithium battery cell 8.
[0031] Furthermore, in order to enable the top plate push rod 5 to move stably back and forth in the horizontal direction, a push rod limit seat 611 is fixedly installed on the fixed mounting plate 61, and a movable slot 612 is opened on the push rod limit seat 611. The top plate push rod 5 passes through the movable slot 612 and is connected to the connecting fastener 63.
[0032] Furthermore, in order to obtain better placement stability, foot pads 12 are provided at the bottom periphery of the base plate 1 .
[0033] Working principle of this application fixture:
[0034] By turning the cylinder control switch 11 to the right, the air inlet will open, and the working air pressure will enter the air inlet of the driving cylinder 72 through the air pipe, so that the second push rod 73 is pushed forward, and then the swing member 62 will move downward, thereby driving the top plate push rod 5 forward through the connecting fastener 63. Since the top plate 4 is fixed on the top plate push rod 5, when the top plate push rod 5 moves forward, the top plate 4 also moves forward to support the lithium battery cell 8, and the battery cells to be bundled are clamped by the forward and backward movement principle of the driving cylinder 72.
[0035] After the battery cells are bundled, the cylinder control switch 11 is turned to the left, and the air pressure in the driving cylinder 72 is discharged through the vent port. The second push rod 73 is tightened backward to drive the connecting fastener 63 to move upward, thereby pulling the top plate push rod 5 back, and then the top plate push rod 5 and the top plate 4 are retracted backward together, so that the battery cells are no longer in a clamped state, making it convenient to remove the bundled battery cells.
[0036] This application combines the precise control of the cylinder and the mechanical stability of the tooling to achieve high efficiency, accuracy and low cost in the battery cell stacking process. In addition, this tooling can also realize real-time monitoring and force feedback control of the battery cell stacking process by integrating pressure sensors and control systems, further improving the quality and stability of the battery cell stacking.
[0037] 1. Improve production efficiency: The battery stacking tooling adopts cylinder drive and modular design, making the battery stacking process faster and more efficient. This not only increases the output of the production line, but also helps reduce manufacturing costs.
[0038] 2. Ensure the quality of battery cells: The tooling uses pressure sensor detection data to accurately control the stacking force and achieve uniform distribution of battery cells, which can effectively prevent the battery cells from being deformed or damaged during the stacking process. This helps to ensure the quality and performance of the battery cells and extend the service life of the battery system.
