Description

Technical Field

[0001] This invention relates to the field of new energy battery welding technology, specifically to a new energy battery oblique welding platform. Background Technology

[0002] Laser welding technology for battery cells, as a crucial high-precision processing method in modern industry, is widely and critically applied in the new energy lithium battery industry, playing an indispensable role, especially in the precision assembly of battery cells. This technology fully utilizes the unique properties of laser beams—high energy density, good directionality, and strong controllability—to achieve efficient and reliable connections between internal components of the battery cell.

[0003] In short, the basic principle of laser welding of battery cells is to use a precisely controlled laser beam as a heat source, directly acting on the surface of the cell material to be welded. Within a very short time, the laser energy is absorbed by the material and converted into heat, causing the material to rapidly heat up locally to a molten or semi-molten state. During this process, parameters such as the laser beam's focal position, scanning path, and output power are precisely calculated and controlled to ensure that the quality, strength, and appearance of the weld joint meet design requirements. This technology has applications in multiple fields, including electrode manufacturing, battery packaging, and battery module assembly for new energy lithium batteries.

[0004] In the production process of new energy lithium batteries, protection plates need to be welded to the tabs of the lithium battery cells. Chinese invention patent application number CN202411315625.7 discloses an automatic shaping and welding equipment for battery tabs, including a feeding mechanism, a shaping and cutting mechanism, and a welding mechanism. The feeding mechanism includes several loading mechanisms, each including a first pallet and a lifting device. A transport mechanism is located above the conveyor belt, and a steering device is located on the transport mechanism. A suction cup is located at the bottom of the steering device. The shaping and cutting mechanism includes a worktable with several fixing devices. A first shaping mechanism, a cutting mechanism, and a second shaping mechanism are located on one side of the fixing devices. The welding mechanism includes a loading device, and a turntable is located on one side of the loading mechanism. The turntable has a loading position, a waiting position, a welding position, and a unloading position arranged sequentially. A protection plate conveying assembly is located on one side of the waiting position, including a first supporting device and a clamping device. Welding components are arranged opposite each other above and below the welding position. This automatic battery tab shaping and welding equipment automatically welds the protection board to the battery tabs, greatly improving production efficiency.

[0005] However, the aforementioned automatic battery tab shaping and welding equipment, due to its horizontal welding method (the protection board, battery, and battery tabs are all horizontally positioned during welding), is not suitable for welding protection boards with the wire exit direction facing the battery. When welding protection boards with the wire exit direction facing the battery, on the one hand, the wires of the protection board are easily pressed under the battery, causing the battery tabs and protection board to be uneven during welding, affecting the welding quality; on the other hand, during the protection board transportation process, if the wire exit direction of the protection board is facing the battery, the wires are likely to hit the battery placement platform of the turntable, causing the wires to bend significantly and easily damage the wires. Summary of the Invention

[0006] To overcome the problem that existing battery welding equipment is not suitable for welding protective plates with the welding line direction facing the battery, this invention provides a new energy battery oblique welding platform.

[0007] The technical solution of this invention is as follows:

[0008] A new energy battery oblique welding platform is applied to a welding machine, including a rotating platform, and the circumferential edge of the rotating platform is provided with multiple inclined battery placement platforms for obliquely placing batteries.

[0009] As a preferred embodiment of the present invention, the battery placement surface of the inclined battery placement platform is provided with a plurality of vacuum adsorption ports for adsorbing and fixing batteries.

[0010] As a preferred embodiment of the present invention, the lower end of the side of the inclined battery placement platform away from the center of the rotating platform is provided with a wire-avoiding chamfer.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. By setting an inclined battery placement platform on the rotating platform, the battery can be placed at an angle, which avoids the protection board wires being pressed under the battery and the wires bending when they hit the battery placement platform during transportation. This effectively solves the problem of the conflict between the protection board wire direction and the battery orientation, making the equipment suitable for more types of battery and protection board combinations, and improving the equipment's versatility and applicability.

[0013] 2. By setting a vacuum suction port on the battery placement surface of the inclined battery placement platform, the battery can be firmly fixed on the inclined battery placement platform when the battery feeding mechanism places the battery on the inclined battery placement platform, so as to prevent the battery from slipping off the inclined battery placement platform and ensure the stability and safety of the production process.

[0014] 3. By setting a chamfer at the lower end of the side of the inclined battery placement platform away from the center of the rotating platform, collisions between the protection board and the inclined battery placement platform are further avoided when the protection board is transported over.

[0019] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. It is also stated that the embodiments described below are for illustrative purposes only and are not intended to limit the invention.

[0020] It should be noted that the terms "installation," "setting," "connection," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly defined. Indications of orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used in the application's product, or the orientation or positional relationship commonly understood by those skilled in the art, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. "A plurality" means two or more, unless otherwise explicitly defined.

[0021] Please see Figure 1This embodiment provides a new energy battery inclined welding platform, applied to a welding machine, including a rotating platform 1, with multiple inclined battery placement platforms 2 arranged circumferentially along the edge of the rotating platform 1. During operation, the rotating platform 1 sequentially moves the multiple inclined battery placement platforms 2 to the welding station of the welding machine, so as to cooperate with the welding machine to weld the protective plate onto the tabs of the battery 3, which is placed inclined on the inclined battery placement platforms 2. Because the battery 3 is inclined while the protective plate is horizontal, even if the wires of the protective plate face the battery 3, the wires will not be pressed under the battery 3 or collide with the inclined battery placement platforms 2 and bend significantly.

[0022] The new energy battery inclined welding platform of this embodiment sets an inclined battery placement platform 2 on the rotating platform 1, so that the battery 3 can be placed at an inclination. This avoids the protection board wires being pressed under the battery 3 and the wires hitting the battery 3 placement platform during transportation, which would cause them to bend significantly. It effectively solves the problem of the conflict between the direction of the protection board wires and the orientation of the battery 3, so that the equipment can be used for more types of battery 3 and protection board combinations, and improves the versatility and applicability of the equipment.

[0023] In one embodiment, the battery placement surface of the inclined battery placement platform 2 is provided with several vacuum suction ports for adsorbing and fixing the batteries 3. These vacuum suction ports are used to firmly fix the batteries 3 onto the inclined battery placement platform 2 when the battery feeding mechanism 3 places the batteries 3 on the inclined battery placement platform 2, so as to prevent the batteries 3 from slipping off the inclined battery placement platform 2 and ensure the stability and safety of the production process. At the same time, the lower end of the side of the inclined battery placement platform 2 away from the center of the rotating platform 1 is provided with a wire avoidance chamfer to prevent the protection board from colliding with the inclined battery placement platform 2 when it is transported, thereby preventing the wires of the protection board from being bent or damaged significantly.

[0024] It should be noted that the present invention does not limit the tilt angle of the inclined battery placement platform 2. It is only necessary to ensure that the electrode clamping mechanism of the welding machine can smoothly clamp the protective plate and the electrode of the battery 3 to ensure the welding quality and avoid collision between the protective plate and the inclined battery placement platform 2 when it is transported over.

[0025] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0026] The present invention has been described above with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other situations without modification, are all within the protection scope of the present invention.
