Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery processing, and in particular to a sealing welding device based on lithium battery box processing and a use method thereof. Background Art

[0002] With the development of new energy, the use of batteries is becoming more and more widespread. Among them, lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.

[0003] During the processing of lithium battery boxes, it is necessary to perform sealing and welding operations on them and their components. During the sealing and welding process, they need to be fixed. There are generally three common fixing methods. One is to fix them by manually operating the clamps, one is to clamp them by extending the cylinder, and the last one is to use the cooperation of the deformed spring and the arc sheet to insert the material along the arc sheet, thereby fixing it with the deformed spring.

[0004] During the above-mentioned lithium battery case processing, when manual material fixing is adopted, it is not only time-consuming and labor-intensive, but also requires frequent material fixing. When the cylinder clamping method is adopted, it is necessary to control and wait for the extension or retraction of the cylinder. When a single spring and clamping piece are used alone, when the spring deformation force is too large, it is inconvenient to pick up the material. When the spring deformation force is small, the material fixing effect is poor. For this reason, we propose a sealing welding device based on lithium battery case processing and its use method. Summary of the invention

[0022] S1. Install the material storage tray along the connecting column, then move the rotating piece outward, and use the cooperation of the moving teeth and the rotating teeth to make the rotating column rotate synchronously, so that the other moving piece moves synchronously, until the two rotating pieces extend out of the locking cover together, and at the same time the slider squeezes the reset spring, and then rotates the rotating piece ninety degrees, and then presses the limit block, so that the limit block squeezes the limit spring, and then slightly resets the moving piece, and then loosens the limit block until the notch and the limit groove are engaged, at this time, the rotating piece is used to drive the locking cover to rotate, so that the connecting threaded sleeve and the connecting threaded rod are screwed together, and the material storage tray can be fixed by the locking cover, and then the rotating piece can be retracted into the locking cover;

[0023] S2, control the driving motor to drive the material storage tray to rotate, and then place the material inside the loading sleeve. With the rotation of the material storage tray, the jacking roller rolls along the slope block and gradually moves upward. The jacking roller drives the jacking rod and its jacking sleeve to move upward together, and at the same time compresses the jacking spring, thereby driving the push plate to move upward, and then driving the connecting block to move upward, so that the push rod begins to deflect, thereby causing the rotating rod to start to rotate, so that the clamping rod gradually approaches and clamps the material;

[0024] S3. When the top roller moves to the arc block, the clamping rod completes the clamping and fixing of the material, and then the traveling mechanism drives the sealing welding head to move, and the sealing welding head is used to perform sealing welding processing on the material;

[0025] S4. After the sealing and welding process is completed, the driving motor drives the storage tray to rotate further. When the top roller moves the slope block on the other side, the top roller gradually moves down, causing the clamping rod to gradually stop clamping and move away from the material, and then the material can be taken out from the inside of the loading sleeve.

[0026] Technical effects and advantages of the present invention:

[0027] (1) The lithium battery material is placed on the loading sleeve, and then the turntable assembly starts to drive the loading sleeve and its lithium battery material to rotate. When the ejection assembly starts to contact the special-shaped incomplete ring assembly, the ejection assembly will gradually push up the clamping assembly until the clamping assembly clamps and fixes the lithium battery material. Then, the walking mechanism is used to drive the sealing head to move, so that the sealing head performs sealing welding on the lithium battery material. When the ejection assembly gradually leaves the special-shaped incomplete ring assembly, the ejection assembly starts to reset, and the clamping assembly no longer clamps the lithium battery material. Then, the lithium battery material can be easily taken out, thereby achieving the purpose of clamping and fixing the lithium battery material during processing, and easily taking out the lithium battery material when processing is not required, without frequent control and long waiting time;

[0028] (2) By rotating the hexagon socket bolt to separate the hexagon socket bolt from the mounting threaded hole, the charging sleeve is moved outward to remove the charging sleeve from the storage tray. During installation, since the outer contour of the charging sleeve is a diamond shape, it is also convenient for guided installation. The charging sleeve is inserted into the mounting groove, and then the hexagon socket bolt is turned over so that the hexagon socket bolt is screwed into the mounting threaded hole. This makes it convenient for users to replace the charging sleeve and the components inside the charging sleeve, so that charging sleeves of different sizes can be adapted to lithium battery materials of different sizes.

[0029] (3) The connecting groove on the material storage tray is inserted along the connecting column, and then the locking cover is rotated so that the connecting threaded sleeve and the connecting threaded rod are screwed together until the locking cover and the bearing ring cooperate to fix the material storage tray, and the locking cover can be rotated using the turning handle assembly, which is convenient for the user to install or remove the material storage tray, and the turning handle assembly can be folded up later.

When the ejecting component 6 starts to contact the special-shaped incomplete ring component 8, the ejecting component 6 will gradually push up the clamping component 5, so that the clamping component 5 gradually approaches the lithium battery material, until the clamping component 5 clamps and fixes the lithium battery material, and then the walking mechanism 2 is used to drive the sealing head to move, so that the sealing head is used to perform sealing and welding processing on the lithium battery material. When the ejecting component 6 gradually leaves the special-shaped incomplete ring component 8, the ejecting component 6 begins to reset, and the clamping component 5 no longer clamps the lithium battery material, and then the lithium battery material can be easily taken out, so that the lithium battery material can be clamped and fixed during processing, and the lithium battery material can be easily taken out when processing is not required, and there is no need for frequent control and waiting for a long time. The walking mechanism 2 can drive the sealing head to realize X-axis and Y-axis movement, and can also drive the sealing head to move downward. The walking mechanism 2 can be obtained through the existing technology and will not be described in detail here.

During installation, since the outer contour of the charging sleeve 4 is a rhombus, it is also convenient for guided installation. The charging sleeve 4 is inserted into the mounting groove 701, and then the hexagon socket bolt 703 is turned over so that the hexagon socket bolt 703 is screwed into the mounting threaded hole 704.
