Description

Technical Field

[0001] The present application relates to the technical field of battery assembly equipment, and in particular to a wire harness assembly device and a battery assembly system. Background Art

[0002] In the current battery module production process, wire harness assembly has long relied on manual labor. Workers must pick up wires one by one and manually align the battery module connections. Assembling a single module takes a long time, making it difficult to meet the explosively growing production capacity demands of the new energy vehicle industry. Furthermore, manual labor is susceptible to fatigue and lack of proficiency, leading to deviations in wire harness positioning, resulting in improper connections, excessive contact resistance, and even the risk of module short circuits. Furthermore, wire harnesses require frequent bending and twisting during assembly, which can easily cause internal wire fractures, making them difficult to detect visually, posing a safety hazard. The wire harness assembly process contributes significantly to the total labor cost of battery modules, and with the increasing labor shortage, companies face continued pressure to increase wages. Existing automation attempts (such as industrial robots directly grasping wire harnesses) have been hindered by the flexibility and entanglement of the wire harnesses, as well as the lack of adaptive positioning mechanisms, resulting in high equipment failure rates and high maintenance costs.

The first connection position 51 and the second connection position 52 corresponding to the same wiring harness 6 can be examples of the positive electrode of the first and the negative electrode of the second of the two adjacent battery cells 50 of the battery module 5, respectively. The first connection position 51 and the second connection position 52 corresponding to the same wiring harness 6 are defined as a connection position pair, as shown in FIG.

[0083] Optionally, the in-position sensing portion 43 may be a photoelectric sensor, which may be fixed to the bracket portion 13. When the battery module 5 is transported to the installation position by the transmission portion 41, the in-position sensing portion 43 detects the in-position information of the battery module 5, and then sends a signal to the transmission portion 41 to stop the transmission portion 41, thereby driving the material transfer component 1, the material support component 2 and the material locking component 3 to assemble the wiring harness 6 of the battery module 5 that has entered the installation position.

[0084] An embodiment of the second aspect of the present application also provides a battery assembly system, including the wiring harness 6 assembly device described in any of the above embodiments, and thus has all the beneficial technical effects of the wiring harness 6 assembly device, which will not be repeated here.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
