Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery welding, and particularly relates to a fixing device and a fixing method for lithium battery welding. Background Art

[0002] With the rapid development of modern electronic devices, electric vehicles and other industries, the demand for lithium batteries as an efficient and clean energy storage device is increasing continuously. In the production process of lithium batteries, the welding process is a crucial link, which involves electrically connecting the positive and negative electrodes of the battery to other components (such as electrode connection pieces, protection circuits, etc.).

[0003] Currently, in the lithium battery welding operation, usually one end of the battery is welded first, and after completion, the battery is removed from the fixing device and then re-clamped for welding the other end. Repeatedly clamping the lithium battery is a time-consuming process. In a large-scale production environment, each lithium battery needs to go through two clamps, which greatly increases the welding cycle of a single battery. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose a fixing device for lithium battery welding.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: In the first aspect, the present invention provides a fixing device for lithium battery welding, including an equipment table. Two sliding grooves are opened on the equipment table, and two sliding plates are slidably connected together in the two sliding grooves. A bidirectional screw is rotatably connected in one of the sliding grooves through a bearing. The two threaded sections on the bidirectional screw have opposite thread directions. A first motor is fixedly connected to the equipment table, and the bidirectional screw is driven to rotate by the first motor. A flipping structure is provided on the sliding plate. The flipping structure mainly consists of two rotating shafts. The two rotating shafts are respectively rotatably connected to the sliding plate. One end of the rotating shaft is fixedly connected with a clamping plate. One end of one of the rotating shafts is fixedly connected with a first gear. A first rack is meshed with the first gear. A rectangular groove is opened on one of the sliding plates, and the first rack is slidably connected with the rectangular groove. A threaded rod is rotatably connected in the rectangular groove through a bearing. A second motor is fixedly connected to one of the sliding plates, and the threaded rod is driven to rotate by the second motor.

[0006] The effects achieved by the above components are as follows: Place the lithium battery on the equipment table. The output end of the first motor is connected to the bidirectional screw through a reducer and a coupling. Start the first motor, and the first motor drives the bidirectional screw to rotate, thereby causing the two sliding plates to slide synchronously and reversely, enabling the two clamping plates to clamp the lithium battery. The output end of the second motor is connected to the threaded rod through a reducer and a coupling. The model of the second motor is 17HS4401. First, connect the power supply to energize the control system of the second motor. After one end of the lithium battery is welded, start the second motor to drive the threaded rod to rotate, causing the first rack to slide, and then causing the first gear to drive the rotating shaft to rotate 180 degrees, further driving the lithium battery to flip, facilitating welding of the other end, thus avoiding the time-consuming process of repeatedly clamping the lithium battery. In a large-scale production environment, each lithium battery needs to undergo two clamps, which greatly increases the welding cycle of a single battery.

[0012] The effects achieved by the above components are as follows: When the positioning rod slides in the sliding groove, the spring is in a stretched state. Therefore, when the first rack slides to a specified position, the positioning rod contacts the card slot, and the positioning rod is clamped into the corresponding card slot under the action of the elastic force of the spring rebound, making the operation more convenient.

[0019] Preferably, four cylinders are fixedly connected to the support plate, and the sliding rod is slidably inserted into the equipment table.

[0020] The effects achieved by the above components are as follows: The four sliding rods are limited and slide on the equipment table, making the movement process of the support plate more stable.

In a large-scale production environment, each lithium battery needs to go through two clamps, which greatly increases the welding cycle of a single battery. When the lithium battery is in different positions, the corresponding positioning rod can be inserted into the corresponding fixing plate to limit the first rack, making the position of the lithium battery more accurate. During the sliding process of the first rack, the positioning rod slides along the chute, and the ball can reduce the friction between the positioning rod and the chute. During the sliding process of the first rack, the positioning rod slides along the chute, and the ball can reduce the friction between the positioning rod and the chute.
