Description
Technical Field
The utility model relates to a surface mounting technology field especially relates to a manual SMT chip mounter.
Background
At the initial stage of designing a circuit, because it is the initial stage, many aspects are not perfect yet, therefore the circuit that has designed can have many unknown problems, so just need the engineer to test, then redesign the circuit, send PCB to the mill and take a design, the paster, wait to receive new circuit board and test again, often will repeat several times at such process of design stage and just can design a qualified circuit board of a section. However, for some companies that produce dedicated robots and customize electronic products, the number of products they design is small, and the number of circuit boards contained in the products is also small. Therefore, if the scheme of attaching chips in a factory is adopted in the initial design stage, a large part of time is consumed in the processing and transportation process, and the development period is delayed. If a small automatic chip mounter is adopted, on one hand, the development cost is increased, and on the other hand, the development time is increased due to the programming of the chip mounter.
For some individual electronic fans, although sometimes it will save much time to hand the designed PCB to the SMT pick-and-place maker for pick-and-place, for the individual electronic fans, the circuit scale they usually design is smaller and the amount required at the early stage is smaller, so that it is not necessary to perform automatic SMT pick-and-place, and since we are handed to a foundry for pick-and-place, there is time consumed by the product during transportation, so that the designable cost is increased, the development period is increased, and the development efficiency of the product is reduced.
Another very straightforward way for an individual to use is to use tweezers for chip placement. There are a number of intuitive drawbacks to using this approach. For example, after we finish the mounting of a chip, first find the required component, then turn the component to the side that we need, and then determine the first pin of the component, after the position of the component is adjusted, we need to perform the last step of operation-manually mount the chip on the PCB board with tweezers, which is a step that is very challenging for the operator, and because of manual mounting, it is a very important problem that we cannot ignore, that is, hand shaking. For some novices, due to the inexperience of this step, it is likely that the above operation will be repeated several times to complete the chip mounting once.
Due to the above problems, there is an urgent need for a chip-mounting machine that is free from programming, simple in operation, easy to expand, capable of saving development period, free from environmental constraints, and capable of greatly improving the chip-mounting efficiency, for groups that only have a need for small-lot circuit patches, such as dedicated robots, electronic product customization companies, and electronic enthusiasts.
