Tab film and adapting nickel tape conveying control device and method

Abstract

The invention relates to a tab film and adapting nickel tape conveying control device. The device comprises a case and a PLC control system, wherein the case is provided with a master tape conveying line and a sub-tape conveying line, the master tape and sub-tape conveying lines are distributed in parallel on the front and back sides of the case, an adapting welding station and an adhesive tape thermal compounding station are sequentially arranged above the master tape conveying line, the output end of the master tape conveying line is provided with a master tape cutting mechanism, a sub-tapecutting mechanism is arranged below the output end of the sub-tape conveying line, an adapting sub-tape clamping mechanism used for conveying a sub-tape to a master tape is arranged below the output end of the sub-tape conveying line, and the case is provided with a first automatic monitoring device for monitoring the two edge positions of an adapting nickel tape, and a second automatic monitoringdevice for monitoring the two edge positions of a composite adhesive tape. The tab film and adapting nickel tape conveying control device has the advantages that relative positions of the adapting nickel tape and the composite adhesive tape can be automatically monitored, the product quality stability is improved, the equipment utilization rate is improved and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of preparation of aluminum-to-nickel tabs, in particular to a transmission control device and method for tab glue and nickel-turned belts. Background technique [0002] In the aluminum-to-nickel tab production process, in the production of aluminum strip tabs, a certain length of nickel strip is cut off according to the production process and then welded together with the aluminum strip, and then flows into the next thermal compound glue process for production. Tab glue, the tab is divided into upper glue, intermediate matrix, and lower glue. The distance L between the tab glue and the end face of the transfer nickel belt has a certain accuracy of ±0.3mm. In actual production, there are two specifications for the distance L. , one such as figure 1 As shown, a part of the lug glue is overlapped with the transfer nickel strip and compounded on the nickel strip, the overlapping part is the distance L between t...

AI Technical Summary

Problems solved by technology

Due to the error of nickel belt transfer, image 3 The cumulative error of the main belt feeding mechanism shown causes the dimension L to be out of tolerance

As the specifications and shapes of lithium batteries are getting smaller and smaller, the requirements for the tabs are getting higher and higher, and L out-of-tolerance will cause short-circuit explosion after battery assembly

[0003] Because the production of tabs is a continuous compound production of multiple lines, the existing equipment cannot achieve automatic alarms and mainly relies on manual inspections. This manual method has poor reliability on the one hand, and the labor intensity of workers is high. It is necessary to walk back and forth between the machines. Increase the probability of workers' work-related injuries; on the other hand, problems cannot be found in time. When manual inspections confirm that there are out-of-tolerance quality defects, the coiled materials will be cut off and the starting point of the problem will be searched forward, resulting in batches of materials being scrapped, making the materials More scrap and can cause downtime issues

[0004] However, the visual IA monitoring and alarm system on the market has a complex structure and system, and the cost is hundreds of thousands per unit. It is expensive and difficult to popularize, transform and install.
