Problems solved by technology

[0004] Due to the different use environments, it is required to arrange the batteries in different ways, which may be L-shaped or square. However, in the existing welding machines, the electrode rods that are in contact with the batteries are fixed on the welding head, and the welding is different. When combining batteries with different shapes, it is necessary to manually move the position of the battery pack on the placement platform to weld the corresponding electrode rods, which greatly reduces the efficiency of battery pack welding and is not conducive to batch automatic welding of battery packs.

Embodiment 1

[0038] Embodiment 1: A battery pack welding execution device 1, such as Figure 1 to Figure 3 As shown, it includes an electrode rod 2, a clamp 3 for clamping the electrode rod 2, and a push-down driving mechanism 6 that drives the clamp 3 to move so that the lower end of the electrode rod 2 is pressed on the battery pack. The shape of the electrode rod 2 is a cuboid , the four vertices of its lower end face are welding points that can be contact-welded with the nickel sheet, and the number of clamps 3 can be one or multiple, and each clamp 3 holds at least one electrode rod 2. In this implementation In the example, the number of clamps 3 is preferably two, and each clamp 3 includes an elastic clamping block 301 and a clamping block 302, and each elastic clamping block 301 clamps an electrode rod 2, elastic clamping The block 301 is made of elastic metal material, and there is a clamping groove 303 vertically penetrating through the elastic clamping block 301 on the top, inser...

Embodiment 2

[0045] Embodiment 2: a battery pack welding robot, such as Figure 4 As shown, including the above-mentioned embodiment 1, the battery welding robot includes a six-axis robot 27. The lower end of the willow-axis robot is placed on the ground, and the upper end is a free end. The free end is fixedly connected to the battery pack welding actuator 1. The six-axis robot 27 For the existing six-axis robot 27, the battery pack welding actuator 1 is installed on the six-axis robot 27, and the six-axis robot 27 can drive the battery pack welding actuator 1 to move in multiple directions, so that the six-axis robot 27 can accurately Position it to the position where the battery pack is to be welded.

[0046] The working process of this embodiment is as follows: the six-axis robot 27 is placed in the workshop, and the battery pack welding actuator 1 is controlled by the six-axis robot 27 to move, so that the electrode rod 2 on the battery pack welding actuator 1 can be vertically downwa...

Embodiment 3

[0047] Embodiment 3: A battery pack welding production workstation, such as Figure 5 and Figure 6 As shown, it includes the above-mentioned embodiment 2. In addition, it also includes a frame 30. The frame 30 is provided with a feed delivery mechanism 28 for transferring the battery pack to the six-axis robot 27. The feed delivery mechanism 28 includes a feed delivery mechanism 28. The material conveyor belt 2801 and the feed drive motor (not shown in the figure) driving the feed conveyor belt 2801 drive, the feed drive motor works, and drives the feed conveyor belt 2801 to transmit. The number of battery pack welding robots is two, respectively located in the feed On the left and right sides of the conveyor belt 2801, the battery pack is conveyed between the two battery pack welding robots through the feed conveyor belt 2801, and the two battery pack welding robots can weld the battery pack at the same time, which greatly improves the welding efficiency; rack 30 The output...

Abstract

The invention discloses a battery pack welding execution device, a robot and a battery pack welding production workstation. The battery pack welding execution device comprises an electrode bar, a clamp used for clamping the electrode bar and a downward-pressing driving mechanism for driving the clamp to move so as to enable one end of the electrode bar to be pressed downward on a battery pack; anda self-rotating body which extends in the downward-pressing direction of the electrode bar and is fixedly connected with the clamp and a rotating driving part which drives the self-rotating body to rotate so as to drive the electrode bar to rotate around the axis of the self-rotating body are arranged on the downward-pressing driving mechanism. The production efficiency of welding is greatly improved, the labor burden is reduced, the welding execution device is suitable for large-scale welding production of the battery pack, and in the whole battery pack welding workstation, welding and carrying moving of the battery pack are realized through the robot, so that the automation degree is relatively high, and the welding efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of product welding, in particular to a battery pack welding execution device and a battery pack welding production workstation. Background technique [0002] Lithium batteries have been widely used due to their advantages such as high voltage, large capacity, small size, light weight, and wide operating temperature range. In the field of automobiles, most of the power batteries used in electric bicycles, motorcycles, electric vehicles and other fields are battery packs connected in series by multiple single batteries through nickel sheets. At present, the existing battery spot welding process, There are problems of low welding efficiency and unstable welding quality. [0003] In order to solve the above problems, in a Chinese patent document with the patent application number "201320865651.8", a four-point resistance welding machine is described, which has a support base, a height adjustment device erected on the sup...
