Circuit enabling continuous power supply during battery replacement process

Abstract

A circuit enabling continuous power supply during a battery replacement process comprises a first rectifier bridge, a second rectifier bridge, a first plug, a second plug, a first power supply moduleand a second power supply module, wherein the first rectifier bridge comprises a first diode, and the second rectifier bridge comprises a second diode, the first diode is electrically connected with the negative electrode of the second diode; the first power supply module is electrically connected with the first rectifier bridge through the first plug; and the second power supply module is electrically connected with the second rectifier bridge through the second plug. When a battery of a material receiving machine is replaced, the two groups of batteries can supply power in parallel without powering off the machine. The working efficiency of the material receiving machine is improved.

Description

technical field [0001] The invention relates to a battery power supply circuit, in particular to a circuit for continuously replacing batteries. Background technique [0002] With the development of the electronics industry, surface mount technology is more and more widely used in the manufacturing of electronic products. Surface mount technology is to use SMD devices to realize the continuous assembly and automation of production of electronic products. [0003] However, the length of the material tape is limited, and the production line is shut down due to the replacement of the material tape during production, resulting in a loss of efficiency. In order to reduce the number of downtimes and time wasted for replacing material belts, the current production enterprises manually connect multiple material belts and stick together multiple material belts, which will consume a lot of labor costs and bring safety hazards to the personal safety of the staff. And work efficiency ...

In order to reduce the number of downtimes and time wasted for replacing material belts, the current production enterprises manually connect multiple material belts and stick together multiple material belts, which will consume a lot of labor costs and bring safety hazards to the personal safety of the staff. and low work efficiency

Manual splicing of SMD strips has been unable to meet the industry's requirements for the quantity and quality of strips. It has become a trend to use mechanized and automated splicing of strips instead of manual splicing.

[0004] At this stage, the feeders on the market generally use AC to DC voltage to power the feeder. The feeder that uses AC-DC rectification power supply needs to work within the range of power frequency AC, and cannot move the range, and the mains power is cut off. After that, the splicer cannot work; the splicer powered by the energy storage battery needs to be powered off and shut down when the battery is replaced.
