DETAILED DESCRIPTION

[0016] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. The components of the embodiments of the present invention generally described and shown in the accompanying drawings herein can be arranged and designed in a variety of different configurations.

[0017] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements.

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figures 1 to 3 As shown, a new energy battery module bus assembly device of this embodiment is used for installing power battery module bus components. The new energy battery module bus assembly device includes a conveying system 1. A first assembly station and a second assembly station are arranged along the conveying direction of the conveying system 1. The conveying system 1 is used to convey the battery module to the first assembly station and the second assembly station.

[0020] The first assembly station is provided with a first visual unit 31, a bus bar material bin 8 and a robot 2. The first visual unit 31 is arranged above the conveying system 1. The bus bar material bin 8 and the robot 2 are arranged on one side of the conveying system 1. The bus bar material bin 8 is used for feeding the bus bar. There are two bus bar material bins 8, which are respectively located on both sides of the robot 2. The robot 2 is used to grab the bus bar in the bus bar material bin 8 and install it on the battery module. The first visual unit 31 is used for identification and positioning, so that the robot 2 can assemble the bus bar to the correct position.

[0021] Specifically, the bus bar material bin 8 includes a sliding cylinder 82, which is connected to a material tray 83. An in-position proximity sensor 81 and a loading proximity sensor 84 are respectively provided on the same side of both ends of the sliding cylinder 82; the bus bar loading method is semi-automatic loading. After the material tray 83 equipped with the bus bar is manually placed in a fixed position, the sliding cylinder 82 automatically moves the material tray to the robot grabbing position to realize the feeding of the bus bar assembly.

[0022] The second assembly station is provided with a second visual unit 32, a truss manipulator 4 and a screw feeding device 7. The truss manipulator 4 can realize movement in three directions of XYZ. The truss manipulator 4 is provided with a tightening mechanism 5 and a welding mechanism 6. The welding mechanism 6 is laser welding, which has the characteristics of low heat input, small welding deformation, and no influence of electromagnetic field. The second visual unit 32 is arranged above the conveying system 1, and the truss manipulator 4 and the screw feeding device 7 are arranged on one side of the conveying system 1. The screw feeding device 7 feeds the tightening mechanism 5. The second visual unit 32 is used for identification and positioning, so that the tightening mechanism 5 and the welding mechanism 6 can weld and tighten the busbar.

[0023] The first visual unit 31 and the second visual unit 32 constitute a visual recognition system, and the visual recognition system is implemented using existing technology.

[0024] The main working process and principle of new energy battery module busbar assembly equipment are:

[0025] The tray 83 with the bus installed is placed manually, and the sliding cylinder 82 drives the tray 83 to leave the loading proximity sensor 84 position and slide to the position of the in-place proximity sensor 81. The in-place proximity sensor 81 receives a signal, and the tray 83 is in place at this time; the conveying system 1 conveys the battery module processed in the previous process to the first assembly station, the first visual unit 31 identifies the bus position, the robot 2 grabs the bus from the bus bin and installs the bus on the battery module according to the position identified by the first visual unit 31. After the installation is completed, the conveying system 1 conveys the battery module to the second assembly station. The equipment is set in advance according to the process requirements of the battery module to weld and tighten the bus. If tightening is required, the tightening mechanism 5 tightens the bus on the battery module according to the position identified by the second visual unit 32, and the tightening screws are supplied by the screw feeding device 7. If welding is required, the welding mechanism 6 welds the bus on the battery module according to the position identified by the second visual unit 32, and finally completes the assembly of the bus on the battery module.
