Abstract
Description
Technical Field
[0001] The utility model relates to the field of extrusion devices, in particular to a visual battery extrusion device. Background Art
[0002] In the existing lithium battery pack module, multiple single cells are usually arranged in sequence and closely attached to each other, and then bundled through end plates and side plates by an extrusion tooling. During the assembly process of the battery pack, it is necessary to detect the cells to check whether the external dimension data of the cells meets the requirements. Among them, it is necessary to detect the appearance of the cells. During the actual detection process, in order to ensure that the cells can be installed in a predetermined installation space, it is necessary to detect whether the overall dimensions of the cells meet the regulations.
[0003] Publication (Announcement) Number: CN220145748U, a module extrusion tooling, including a cylinder, the output end of the cylinder is movably connected to the outer wall of a push rod, one side of the cylinder is fixedly connected to the top of an operation platform through a fixed plate, the top of the operation platform far away from the cylinder is fixedly connected to the bottom of a control box, and the outer wall of the control box is fixedly connected to a pressure gauge through bolts. By using the cylinder to control and set a minimum value and a maximum value for the specified pre-tightening force of the cell module body, the maximum value cannot exceed the specified pre-tightening force of the cell module body. When the cylinder extrudes the cell module body and reaches the specified dimensional position, as long as the pre-tightening force displayed on the pre-tightening force detection device is within the set range, and at the same time, the green light on the control box display lights up to indicate qualified. At this time, the two side plates are fastened to maintain the pre-tightening force released after the cell module body is grouped, which brings convenience to the use of the staff.
[0004] For a module extrusion tooling with the above structure, it can only customize the dimensional requirements of the cell module body through the magnetic switch on the cylinder. When the cylinder pushes the push rod inward for extrusion, as long as the magnetic switch lights up, it stops advancing to ensure the dimensional position of the module. There is no industrial camera or other equipment to detect the appearance of the cells, and it is impossible to accurately judge whether the appearance of the cells is affected by extrusion and exceeds the set range value, which is very troublesome. Due to the lack of detection equipment such as industrial cameras, it is impossible to accurately check whether there are abnormalities in the cells, impossible to detect the yield rate of the cells, impossible to judge whether there are unqualified cells among the extruded cells, and impossible to ensure the yield rate of the cells.

[0019] As Figures 1 - 4 shown, a visual battery extrusion device includes a frame 1. An extrusion power mechanism 2 is provided on the top surface of the frame 1. The extrusion power mechanism 2 includes a positioning seat 12 fixed on the top surface of the frame 1, an electric cylinder 11 fixedly arranged on the side surface of the positioning seat 12, and a telescopic rod 13 connected to the output end of the electric cylinder 11. A base 7 is fixedly arranged on the top surface of the frame 1. The base 7 is perpendicular to the frame 1. Extrusion plates 14 are respectively arranged on the side surface of the base 7 and the end of the telescopic rod 13 far from the electric cylinder 11. A side limiting plate 8 is arranged on the top surface of the frame 1. The side limiting plate 8 extends along the length direction of the frame 1. The area between the extrusion plate 14 and the side limiting plate 8 forms a placement area 18. By setting the placement area 18, the bundled battery cells 19 can be placed, facilitating the subsequent extrusion of the battery cells 19 by the extrusion power mechanism 2. An industrial camera 3 is installed on the top surface of the frame 1 through a fixed rod 17. The industrial camera 3 is located above the placement area 18. After the battery cells 19 are bundled and placed in the placement area 18, the electric cylinder 11 drives the telescopic rod 13 and the extrusion plate 14 to move to extrude the placement area 18. The industrial camera 3 detects the extruded battery cells 19. The side limiting plate 8 extends along the length direction of the frame 1, effectively restricting the lateral movement of the battery cells 19 during the extrusion process, ensuring the directionality and consistency of the extrusion operation, helping to prevent the battery cells 19 from shifting during the extrusion process, and improving the accuracy of the operation.
[0020] A control panel 4 is fixedly provided on at least one side of the frame 1, a main control circuit board is provided inside the control panel 4, a power switch 5 is movably provided on the surface of the control panel 4, the power switch 5, the electric cylinder 11 and the industrial camera 3 are electrically connected to the main control circuit board respectively, a power interface 9 for supplying power to the main control circuit board is provided at the bottom of the electric cylinder 11 to ensure stable power supply to the control panel 4, the electric cylinder 11 and the industrial camera 3, and a communication interface 10 supports data exchange with the control system, a communication interface 10 for information transmission is provided at the bottom of the electric cylinder 11, and the power interface 9 is located near On one side of the frame 1, a plurality of pulley feet 6 are provided at the bottom of the frame 1, and the plurality of pulley feet 6 are all on the same horizontal plane, which is convenient for moving and carrying the extrusion device. The positioning seat 12 is provided with a fastening block 15, and the fastening block 15 is sleeved with a slidable positioning rod 16, and one end of the positioning rod 16 is connected to the extrusion plate 14. When in use, the electric cylinder 11 drives the telescopic rod 13 to move, so that the extrusion plate 14 moves. At the same time, under the driving action of the electric cylinder 11, the positioning rod 16 moves with the telescopic rod 13, so that the positioning rod 16 slides along the fastening block 15, and the extrusion plate 14 is pushed toward the direction of the battery cell 19.
[0021] Industrial camera 3 uses a CCD camera, which can capture and convert light signals into electrical signals, and then generate digital images for subsequent processing and analysis.
[0022] When a visual battery extrusion device of this embodiment is used, after the power interface 9 is powered on, the power switch 5 is started, and then the corresponding visual offset data and the extrusion force of the extrusion power mechanism 2 are set on the control panel 4, the battery cells 19 are bundled and formed and placed in the placement area 18. After the arrangement is completed, the extrusion power mechanism 2 is started, and the electric cylinder 11 drives the telescopic rod 13 and the extrusion plate 14 to move to extrude the placement area 18. When the extrusion power mechanism 2 completes the extrusion, the extruded battery cells 19 are detected by the industrial camera 3, and the length and width data of the module set in advance are compared to check the extruded battery cells 19. Whether the group shape range exceeds the set value. If the shape parameter is within the set value range, the packaging and fixing process is started.

After the extrusion power mechanism 2 is released, the electric cylinder 11 drives the telescopic rod 13 and the extrusion plate 14 to move so that the extrusion plate 14 leaves the placement area 18. After the battery cell 19 is extruded and inspected, the unqualified battery cell 19 is discharged manually or by using tools such as a robot, and then the extrusion work is performed again. The working principle and working process of the industrial camera 3 belong to the existing technology and will not be explained in detail here.
