Abstract
Description
Technical Field
[0001] This utility model relates to a battery assembly device, and more particularly to a battery cell insertion device. Background Technology
[0002] The battery cell insertion device is a key piece of equipment in lithium battery manufacturing, used to precisely insert the battery cells into metal or plastic casings to ensure the reliability of subsequent packaging and sealing processes. Existing technologies typically use a robotic arm to grasp the battery cell, along with a guide groove or positioning mechanism, and a linear drive device (such as a cylinder or servo motor) to vertically press the battery cell into the casing.
[0003] Current battery cell insertion devices rely on mechanical guiding structures for positioning accuracy. This makes the concentricity of the battery cell and the casing susceptible to cumulative errors or vibrations, leading to scratches on the electrode sheets or deformation of the casing. At the same time, the material handling components lack active angle adjustment capabilities during the pressing of the battery cell into the casing. They cannot dynamically adjust the battery cell angle to accommodate minor casing deviations (such as casing injection molding deformation or assembly tolerances), and may even damage the internal structure of the battery cell. As a result, uneven gaps may still occur after the battery cell is inserted into the casing due to angle deviations, causing local stress concentrations that require subsequent manual intervention, thus restricting production efficiency and yield improvement. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a battery cell casing device.
[0005] The technical implementation scheme of this utility model is as follows: a battery cell insertion device, comprising a main frame, a first transmission component, a mounting base, a second transmission component, a lifting component, a rotating base, a floating frame, a rotating plate, a movable support rod, an electric cylinder, a chuck base, and a first vision module. The first transmission component is provided on both the front and rear sides of the upper part of the main frame. Two mounting bases are provided at the lower part of the main frame, arranged in parallel, with their arrangement direction intersecting the transmission path of the first transmission component in a cross shape. The two mounting bases are respectively used to install material transfer components for transmitting the battery cell and the housing. The first transmission component drives the second transmission component to move left and right. The second transmission component is equipped with a lifting component. The lifting component moves back and forth. A rotating seat is installed at the bottom of the lifting component. The rotating seat consists of a drive motor and a rotating plate. Four movable support rods are arranged in a ring at the bottom of the rotating plate. A floating frame is provided between the telescopic rods of the movable support rods. The ends of the telescopic rods are all hinged to the floating frame. Four electric cylinders are vertically arranged on the rotating plate.

[0009] In one embodiment, the system further includes a dustproof frame, a window frame, and a viewing window. The dustproof frame surrounds the main frame and has a viewing window for mounting a transparent protective panel. Two window frames are provided on both the front and rear sides of the dustproof frame.

Detailed Implementation
[0022] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] A battery cell casing device, such as Figure 1-6As shown, the system includes a main frame 1, a transmission component 2, a mounting base 21, a transmission component 3, a lifting component 4, a rotating base 41, a floating frame 5, a rotating plate 51, a movable support rod 52, an electric cylinder 53, a chuck base 6, and a vision module 7. The main frame 1 has transmission components 2 on both the front and rear sides at its upper part. The lower part of the main frame 1 has two mounting bases 21 arranged in parallel, with their orientation intersecting the transmission path of the transmission components 2. The mounting bases 21 are used to mount material transfer components; one material transfer component transfers the outer shell, and the other transfers the battery cell. The parallel arrangement of mounting bases 21 and their cross-shaped layout with transmission component 2 ensure that the transmission paths between the battery cell and the casing are independent and do not interfere with each other, improving transmission stability. Transmission component 23 is located between transmission components 21. Transmission component 21 drives transmission component 23 to move left and right. A lifting component 4 is mounted on transmission component 23. When the lifting component moves, it passes over the two mounting bases 21. Transmission component 23 drives the lifting component 4 to move back and forth. Through the coordinated action of transmission components 21 and 23, the lifting component 4 is precisely positioned in a two-dimensional plane, ensuring that the battery cell can accurately reach the top of the casing. The unit is equipped with a rotating base 41, which consists of a drive motor and a rotating plate 51. Four movable support rods 52 are arranged in a ring around the lower part of the rotating plate 51. A floating frame 5 is provided between the telescopic rods of the movable support rods 52. The ends of the telescopic rods are all hinged to the floating frame 5. Four electric cylinders 53 are vertically arranged on the rotating plate 51. The drive rods of the electric cylinders 53 are all hinged to the floating frame 5 through floating joints. The four electric cylinders 53 are arranged in a circle. The extension and retraction of the four electric cylinders 53 can control the balance of the floating frame 5 to adjust the angle of the clamped battery cell. When the battery cell is affected by manufacturing tolerances or transmission deviations... When the angle deviates, the electric cylinder 53 can independently extend and retract to adjust the tilt angle of the floating frame 5, so that the concentricity error between the battery cell and the shell is controlled within ±0.1°, effectively avoiding scratches on the electrode or deformation of the shell. The floating frame 5 is equipped with a disassembly and assembly mechanism, and a chuck seat 6 is installed at the bottom of the disassembly and assembly mechanism. The chuck seat 6 is used to install the chuck for clamping the battery cell. A vision module 7 is provided on one side of the floating frame 5. The lens of the vision module 7 faces the chuck seat 6. The vision module 7 can detect the position and angle of the battery cell on the chuck seat 6 in real time, providing data support for the adjustment of the electric cylinder 53 and forming a closed-loop control.
[0024] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes a mounting bracket 71 and a vision module 72. The mounting bracket 71 is fixedly installed on the lower inner side of the main frame 1. The vision module 72 is rotatably installed on both the front and rear sides of the upper part of the mounting bracket 71. The mounting bracket 71 is located in the area between the two mounting seats 21. When the chuck picks up the battery cell and moves it to the side of the housing, it will pass through the detection area of the vision module 72. The vision module 72 can perform secondary calibration on the relative position of the housing and the battery cell to ensure the concentricity and gap uniformity of the battery cell and the housing before entering the housing, thereby improving the success rate of entering the housing.
[0025] Among them, such as Figure 3-5 As shown, the disassembly and assembly mechanism includes a cylinder 8, a spring 81, a buckle 82, a groove 820, a magnetic base 83, and a magnetic block 84. A magnetic base 83 is installed in the upper part of the floating frame 5. Cylinders 8 are symmetrically arranged on the left and right sides inside the floating frame 5. The ends of the moving rods of the cylinders 8 extend into the floating frame 5. Buckles 82 are fixed on the moving rods of the cylinders 8. Springs 81 are installed on the buckles 82. The other end of the springs 81 is connected to the floating frame 5. A magnetic block 84 is provided on the top of the chuck seat 6. Grooves 820 are opened on the left and right sides of the upper part of the chuck seat 6. The chuck seat 6 is engaged with the buckle 82 through the grooves 820, and the magnetic base 83 is in contact with the magnetic block 84. When the chuck needs to be replaced, the cylinder 8 drives the latch 82 to retract, the spring 81 is compressed, the groove 820 disengages from the latch 82, and at the same time the magnetic base 83 separates from the magnetic block 84, realizing the quick disassembly of the chuck seat 6; during installation, the groove 820 of the new chuck seat 6 is aligned with the latch 82, the cylinder 8 drives the latch 82 to extend, the spring 81 returns to its original position to provide pre-tightening force, and the magnetic base 83 and the magnetic block 84 are attracted and fixed, ensuring that the chuck seat 6 is installed firmly, and the disassembly and assembly time is shortened to within 5 seconds, improving the changeover efficiency.
[0026] When the device starts, transmission component 2 and transmission component 3 work together to drive lifting component 4 to move to the battery cell transfer position. The chuck seat 6, after installing the appropriate chuck via the disassembly and assembly mechanism, grips the battery cell. Vision module 7 detects the battery cell angle and feeds it back to cylinder 53, which adjusts the balance of floating frame 5. Lifting component 4 carries the battery cell to the top of the outer casing, and vision module 72 performs a secondary calibration of the casing and battery cell. Rotating seat 41 drives floating frame 5 to rotate, aligning the battery cell with the casing. Cylinder 53 then fine-tunes the battery cell angle and presses it into the casing, completing the casing insertion action. The entire process involves multi-level visual inspection and floating adjustment.
[0027] In addition, such as Figure 1 , Figure 2 and Figure 6 As shown, the device also includes a placement frame 85, which is located on the lower left side of the main frame 1. When the transmission component 2 3 moves to the left, it will pass over the placement frame 85. The placement frame 85 is used to place multiple chucks in an orderly manner, which facilitates quick replacement and retrieval, reduces downtime caused by chuck replacement, and improves production continuity.
[0028] Furthermore, such as Figure 2As shown, the device also integrates a dustproof frame 9, a window frame 91, and a viewing window 901. The dustproof frame 9 closely surrounds the main frame 1. The viewing window 901 on the dustproof frame 9 is used to install a transparent protective plate, forming a closed protective space that effectively blocks external dust and metal debris from entering, reducing the risk of cell surface contamination. This ensures both the visibility of the operator and the cleanliness of the interior. The four window frames 91 on the front and rear sides form notches in the viewing window 901 to ensure that material transfer components (such as conveyor belts or robotic arms) on the mounting base 21 can pass through smoothly.
[0029] Finally, as Figure 2 As shown, the lower part of the dustproof frame 9 is also equipped with a gas exchanger 10. The gas exchanger is connected to the internal space of the dustproof frame 9 through a circulation pipe. The gas exchanger 10 has a built-in air circulation and filtration module. By circulating the airflow in the dustproof frame 9, it continuously filters and purifies the internal air, effectively removing dust, particulate matter and other pollutants from the air, and further reducing the dust concentration. At the same time, the gas exchanger 10 can also maintain a slightly positive pressure environment inside the device, effectively preventing external pollutants from entering and providing a highly clean working space for the battery cell casing process.

All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
