Technical Field

[0001] This utility model relates to the field of automotive battery cover welding technology, specifically a welding machine for processing automotive battery covers. Background Technology

[0002] As a core process in power battery manufacturing, automotive battery cover welding directly affects the battery's sealing performance, safety, and lifespan. With the rapid development of the new energy vehicle industry, battery pack structures are evolving towards higher energy density and lighter weight. Cover welding technology faces multiple challenges, including material diversification, stringent precision requirements, and the need to improve production efficiency.

The bottom of the turntable is provided with a bearing seat, and the bottom of the turntable is rotatably connected to the top of the bearing seat. A wire feeding wheel is rotatably connected to one side of the turntable, and welding wire is provided in the wire feeding wheel. A first motor drives the upper arm to rotate through a first connecting rod and a first fixed sleeve, so that the upper arm is located in the turntable and in a horizontal state. Then, a second motor drives the lower arm to rotate through a second rotating rod and a second fixed sleeve. At the same time, the laser welding gun is rotated through a rotating component, so that the lower arm rotates into the receiving groove on the upper arm, allowing the entire device to fold up.

[0004] During the production of automotive batteries, a cover plate needs to be welded above the metal top rod of the battery. In existing technologies, the cover plate is generally welded using a laser welding machine as described above. However, during the cover plate welding process, the automotive battery needs to be placed stably on the worktable. However, automotive batteries come in different sizes, and most existing positioning structures for automotive batteries can only stabilize lithium batteries of a single size, which has a limited scope of application and is not convenient for fastening the cover plate. This may cause the cover plate to shift during the laser welding process, thereby reducing the welding quality of the battery cover plate. Therefore, we need to propose a welding machine for processing automotive battery cover plates. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a welding machine for processing automotive battery cover plates, comprising:

[0023] Welding station 1, with a battery slot 2 for placing the car battery pack on welding station 1;

[0024] The clamping mechanism 7, which is set at equal angles on the welding station 1, secures the battery pack at multiple angles.

[0025] The clamping mechanism 8 installed on each set of clamping mechanisms 7 fastens the battery cover plate.

[0026] A drive unit 9 is installed below the welding station 1 to drive multiple sets of clamping mechanisms 7, thereby realizing the synchronous driving of multiple sets of clamping mechanisms 7.

[0027] The clamping mechanism 8 includes a base plate 81 and two sets of L-shaped plates 83. An electric push rod 82 is rotatably mounted on the upper surface of the base plate 81. A connecting shaft 84, which is rotatably connected to the telescopic end of the electric push rod 82, is fixedly connected between the two sets of L-shaped plates 83. Both sets of L-shaped plates 83 are rotatably mounted on the upper end of the clamping mechanism 7, and one end of each set of L-shaped plates 83 is provided with a clamping member 85 for pressing the battery cover. By extending and retracting the telescopic end of the electric push rod 82, the position of the connecting shaft 84 can be moved. The L-shaped plates rotate on the clamping plate 76, thereby flipping the position of the clamping member 85, which facilitates the clamping member 85 to press the battery cover and ensures the stability of the battery cover on the battery pack during welding.

[0028] The clamping component 85 includes a pressure plate 851. Multiple sets of uprights 852 penetrating the L-shaped plate 83 are fixedly connected to the upper surface of the pressure plate 851. Springs 853 located between the pressure plate 851 and the L-shaped plate 83 are sleeved on the outer side of each set of uprights 852. Anti-slip pads are adhered to the lower surface of the pressure plate 851. When the pressure plate 851 is pressed against the battery cover, it will compress the multiple sets of springs 853, increasing the elastic potential energy of the springs 853. This allows the pressure plate 851 to press against the battery cover under the elastic action of the springs 853, ensuring the quality of the welding.

[0029] The clamping mechanism 7 includes a linkage component and a mounting component, with the mounting component driven by the linkage component;

[0030] The mounting components include a movable base plate 74, two sets of connecting posts 75, and a clamping plate 76. The two sets of connecting posts 75 are fixedly connected to the upper surface of the movable base plate 74, and one end of each set of connecting posts 75 is fixed to one side of the clamping plate 76. The two sets of L-shaped plates 83 are rotatably mounted on the upper side of one side of the clamping plate 76. The side view of the connecting posts 75 is L-shaped, which facilitates the movement of the clamping plate 76 above the battery slot 2, thereby facilitating the clamping of battery packs of different specifications.

[0031] The linkage includes a linkage shaft 71 and two sets of directional rods 73. One end of the linkage shaft 71 has an external thread 711 for driving the movable substrate 74. Both sets of directional rods 73 pass through the connecting substrate. The other end of the linkage shaft 71 has a driven bevel gear 72. The welding station 1 has a guide cavity 5 for the movable substrate 74 to slide. A groove 6 is provided on the upper surface of the welding station 1 above the guide cavity 5. The connecting post 75 is slidably disposed in the groove 6. The linkage shaft 71 is perpendicular to the rotating shaft 902, thereby ensuring that the driving bevel gear 903 and the driven bevel gear 72 can mesh and transmit power. At the same time, the external thread 711 on the linkage shaft 71 can drive the movable substrate 74 to adjust its position, thereby facilitating the position adjustment of the clamping plate 76 and realizing the clamping of the battery pack.

[0032] The driving component 9 includes a motor 901 mounted on the lower surface of the welding station 1. The output shaft of the motor 901 is connected to a rotating shaft 902, and the upper end of the rotating shaft 902 is provided with a driving bevel gear 903 that meshes with the driven bevel gear 72. The welding station 1 has an inner cavity 4 located below the battery slot 2. Both the driving bevel gear 903 and the driven bevel gear 72 are located in the inner cavity 4. The motor 901 drives the rotating shaft 902, causing the rotating shaft 902 to drive the driving bevel gear 903 to rotate. The driven bevel gears 72 on the linkage shaft 71 mesh with the driving bevel gear 903, thereby realizing the synchronous driving of multiple clamping mechanisms 7, which is convenient for clamping square battery packs of different specifications and improves practicality.

[0033] The upper surface of the welding station 1 is provided with two sets of welding machine mounting slots 3, and the lower surface of the welding station 1 is fixedly connected with a bracket. The welding machine mounting slots 3 are used to install the laser welding robot. The laser welding robot can be directly installed and used after purchase. The operating principle of the laser welding robot will not be described in detail.

[0034] In use, place the cubic battery pack with the battery cover to be welded into the battery slot 2, start the drive bevel gear 903 on the electric drive rotating shaft 902, so that the drive bevel gear 903 synchronously meshes with the driven bevel gears 72 of the multiple clamping mechanisms 7, thereby causing the driven bevel gears 72 to drive the linkage shaft 71 to rotate, and the external thread 711 on the linkage shaft 71 causes the moving base plate 74 to move along the directional rod 73 in the guide cavity 5, so that the clamping plate 76 is close to the battery pack, which is convenient for clamping and fastening the battery pack.

[0035] Next, the battery cover is placed on the battery pack. The position of the connecting shaft 84 is adjusted by the telescopic end of the electric push rod 82, which causes the two sets of L-shaped plates 83 to flip on the clamping plate 76. This causes the clamping parts 85 to flip and press against the battery cover. The spring force of multiple sets of springs 853 causes the pressure plate 851 to press the battery cover tightly, ensuring the stability of the battery cover during laser welding and thus improving the welding quality of the battery cover.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
