[0022] A steel strip shaping electrical measurement method, comprising the new energy battery fixed steel strip extrusion shaping electrical measurement equipment;

[0023] The electrical measurement method for steel strip shaping includes the following steps:

[0024] Step S1, shaping the steel strip insulation layer: the steel strip is fed into a shaping box, and the outer surface of the insulation layer is first cooled and initially shaped by blowing air through a cleaning nozzle, and then the steel strip enters the first rolling assembly and the second rolling assembly in sequence, and the first rolling assembly cooperates with the first upper roller group and the first lower roller group, and rolls the entering insulation layer to cool and shape it under the action of the first condenser tube; after completing the cooling and shaping once, the steel strip enters the second rolling assembly, and cooperates with the second upper roller group and the second lower roller group, and rolls the entering insulation layer to cool and shape it under the action of the second condenser tube;

[0025] Step S2, electrical testing of the steel strip: after the insulating layer of the steel strip is roller-shaped, the steel strip is sent into the electrical testing box through the electrical testing stretching roller. Before entering the electrical testing box, the appearance of the insulating layer on the steel strip is visually inspected by the appearance inspection component; after the inspection is completed, it enters the electrical testing component, and the vibration motor of the electrical testing component drives the vibration bracket to vibrate, and at the same time drives the steel ball string to move along the transmission direction of the steel strip to perform a piercing conductive test on the insulating layer of the steel strip. At the same time, the conductive brush performs a contact test under the steel ball string.

[0026] The beneficial effects of the present invention are:

[0027] Compared with the existing steel strip preparation, the present invention sequentially extrude and coat the steel strip with an insulating layer, and then cool and shape the insulating layer through a shaping mechanism, and then perform an electrical test through an electrical measuring mechanism after cooling and shaping, and then reel the steel strip after the electrical test, thereby realizing the automated production of the steel strip without manual intervention. This solves the problem of the high difficulty of automated production of packaging steel strips for existing new energy battery packs, saves manpower and material resources, improves the degree of automation, and ensures insulation and safety after electrical testing.

[0028] The extruder in the extrusion coating mechanism is connected to the extrusion die, and the steel strip is guided toward the extrusion die through the guide roller, which ensures the position stability of the steel strip during the extrusion process and realizes the precise extrusion coating of the steel strip. The extrusion die includes a first extrusion flow channel, a second extrusion flow channel and a third extrusion flow channel, which can realize multi-channel extrusion, so that the steel strip can be coated with multiple layers of materials at the same time, which improves the flexibility and diversity of production. The introduction flow channel of the extrusion die can be connected to different extrusion ends to achieve rapid mold change and adjustment, adapt to the extrusion production of steel strips with different specifications and requirements, and reduce the line change time and cost. The shaping mechanism can shape the extruded steel strip according to the needs to ensure that the size and shape of the product meet the requirements, and improve the processing accuracy and consistency of the product. The equipment is equipped with an electrical measurement mechanism, which can measure the steel strip online, monitor the product quality in real time, find problems in time and make adjustments, and improve the product quality control capabilities.

[0029] The shaping mechanism can blow air to cool and clean the outer surface of the insulation layer through the cleaning nozzle, ensuring that the surface of the insulation layer is clean and dust-free, thereby improving the quality and reliability of the insulation layer. The first rolling component performs a single roll forming on the insulation layer, so that the insulation layer can obtain an appropriate thickness and flatness, thereby improving the appearance and performance of the insulation layer. The second rolling component performs a secondary roll forming on the steel strip that has been roll formed once, further processing and adjusting the thickness and flatness of the insulation layer, thereby ensuring the stability of the product size and quality. The setting of the shaping mechanism enables the entire production process to be automated, thereby improving production efficiency, reducing human intervention, and reducing production costs. Through single and secondary roll forming, the insulation layer can be accurately formed, ensuring that the thickness and flatness of the insulation layer meet the requirements, thereby improving the processing accuracy and consistency of the product.

[0030] The electrical measuring mechanism can stretch the tension of the steel strip and transmit it to the electrical measuring box through the setting of the electrical measuring stretching roller, which is conducive to the subsequent electrical performance test. The appearance inspection component is located on one side of the electrical measuring box, which is used to inspect the appearance of the steel strip, including surface quality, flatness, etc., which helps to timely discover surface defects and problems and improve the appearance quality of the product. The electrical testing component is set in the electrical testing box, which can test the electrical properties of the steel strip, including the conductivity, insulation performance and other aspects, to ensure that the product meets the electrical performance requirements. Two sets of electrical measuring stretching rollers are set up, which can transmit the tension of the steel strip more stably and evenly, and improve the accuracy and reliability of the test. The role of the electrical measuring mechanism enables real-time monitoring and testing of the electrical properties and appearance of the steel strip, which is conducive to ensuring product quality and reducing the defective rate in production.

[0031] The electrical test assembly can effectively reduce the impact of external vibration on the test results by setting up mounting brackets, shock-absorbing elements and other structures, thereby improving the stability and accuracy of the test. The vibration motor drives the vibration bracket to vibrate, driving the steel ball string to shake, so that the electrical properties of the steel strip can be fully tested during the test. The conductive brush is located on the lower side of the steel ball string and is used to contact the lower surface of the steel strip to ensure the reliability and accuracy of the electrical test. Multiple sets of steel ball strings are set up to increase the coverage of the test area, which is conducive to a more comprehensive test and analysis of the electrical properties of the steel strip. Driven by a vibration motor, the electrical properties of the steel strip are automatically tested, the test efficiency is improved, human intervention is reduced, and the test time and cost are reduced. Combined with the design of the vibration bracket and the steel ball string, efficient testing of the electrical properties of the steel strip is achieved, which is conducive to improving production efficiency and product quality control.

[0032] The electrical testing method for shaping steel strips realizes precise cooling and shaping of the insulating layer of the steel strip through the shaping box, cleaning nozzle, first rolling assembly and second rolling assembly in step S1, ensuring that the thickness and flatness of the insulating layer meet the requirements and improving the processing accuracy and consistency of the product. The appearance inspection assembly in step S2 is used to visually inspect the appearance of the insulating layer on the steel strip, including surface quality, flatness, etc., which helps to timely discover surface defects and problems and improve the appearance quality of the product. The steel strip is fed into the electrical testing box through the electrical testing stretching roller. Under the action of the electrical testing assembly, the electrical properties of the steel strip are automatically tested, including puncture conductive testing and contact testing, which is conducive to ensuring that the electrical properties of the product meet the requirements. The integrated process of shaping and electrical testing of the steel strip is realized, which improves production efficiency, reduces the defective product rate in production, and reduces labor costs. Comprehensive monitoring and testing of the internal appearance and electrical properties of the insulating layer of the steel strip is realized, which is conducive to improving product quality control capabilities.
