Cleaning device and cleaning method

The present invention relates to a cleaning device and a cleaning method, and more particularly to a cleaning device and a cleaning method for cleaning a plurality of components to be cleaned.

According to the process of general electronic components, miniaturization and massification are common process characteristics, and since these electronic components often have electrical connection requirements or conductivity considerations, these electronic components are usually extremely thin and short, due to The trend of precision and touch, some electronic components are very dust-free in the process of assembly, so the surface of each electronic component and electrical contact usually requires dust-free and 100% dust removal; In the process of manufacturing, in order to facilitate handling and processing, a plurality of electronic components are usually placed in a carrier fixture to be positioned so that the operator can operate or collect the carrier as a unit, and also facilitate automated assembly and assembly. Handling in various processes, but some operations, such as dust removal, are often only carried out in a vacuum-free clean room, but the clean room is not completely dust-free, and the operator is responsible for the electronic components. For the dust-free cleaning method, it is still necessary to manually clean the parts to be cleaned of the electronic components on each carrier board with a cotton swab.

Several problems that can be understood by the conventional cleaning method are: the production volume of electronic components, with the popularity of the products, the output of millions or more than 100 million pieces, the manual cleaning, the efficiency and cost of manpower consumption. Can be imagined! Furthermore, manpower cannot achieve the stability and reliability of the cleaning effect, and it is impossible to check the dust that is hard to see by the naked eye.

Therefore, the object of the present invention is to provide a unit to be cleaned in a carrier. A cleaning device for cleaning the surface to be cleaned.

Another object of the present invention is to provide a cleaning method for cleaning a surface to be cleaned of a component to be cleaned in a carrier.

According to the cleaning device of the present invention, the surface to be cleaned of the component to be cleaned in a carrier plate can be cleaned, comprising: a working track on the surface of the machine table, which is formed to be transported by the carrier plate provided with the component to be cleaned a conveying flow path; a detecting area and a first cleaning area are provided on the working track; a detecting mechanism is disposed in the detecting area opposite to the working track, and includes a detecting device capable of performing displacement, which can be located in the detecting area The board is inspected; a first cleaning mechanism is disposed in the first cleaning area opposite to the working track, and includes a first cleaning module composed of a plurality of cleaning components capable of Z-axis lifting bristles, which can be in the carrier board The surface to be cleaned of the component to be cleaned is cleaned and displaced into the second cleaning zone by Y-axis displacement so that the bristles on which the Z-axis can be lifted and lowered are cleaned by a second cleaning mechanism.

A cleaning method according to another object of the present invention comprises: a feeding step of placing a carrier plate carrying an element to be cleaned on a working track; a detecting step of causing a detecting device in a detecting mechanism The surface to be cleaned of the component to be cleaned in the carrier is tested; in a cleaning step, the other first cleaning zone of the moving carrier on the working track is subjected to a detection by the first cleaning mechanism according to the detection mechanism, and the surface to be cleaned of the component to be cleaned is performed. The cleaning step further comprises the step of displaceing the first cleaning module into the second cleaning zone by Y axially, so that the bristles on which the Z-axis can be lifted and lowered are cleaned by a second cleaning mechanism.

In the cleaning device and the cleaning method of the embodiment of the present invention, since the surface to be cleaned of the component to be cleaned is inspected by the detecting mechanism for fine dust, the manual inspection is difficult to perform, and the first cleaning mechanism is automatically controlled by the first cleaning mechanism. Clean the surface to be cleaned with cleaned parts, not only quickly and surely, but also saves manpower effectively, and also eliminates the possibility of human instability, making the parts such as large and small parts clean and more efficient. indeed.
