TW201509551A - Distributor and its material-detected dust and dirt exclusion method - Google Patents

Abstract

This invention presents a distributor and its material-detected dust and dirt exclusion method. When a material passes through a flow path, the material can be detected. The flow path is constituted by a delivery channel that is connected to one side of the transfer seat, a hollow cavernous channel of the detection zone that is located between on the other side of the transfer seat and the slide base, and a discharge orifice on the slide base, which are all communicated with each other. The detection module is located on the tip side of the detection zone to detect the materials passed through the flow path. The transfer seat is installed with a gas channel and a detection zone, where the gas channel and the detection zone are connected. By use of passing the gas into the gas channel, dust and dirt are removed in the detection zone.

Description

Dispenser and its material detection dust removal method

The present invention relates to a dispenser and a dust removing method thereof, and more particularly to a dispenser for dispensing a material, a detecting section for detecting the material of the material, and a dust removing distributor for the detecting module and The method for removing dirt from the material inspection.

Press, general LED (Light Emitting Diode) belongs to the field of semiconductor microelectronics, and its package form can be various, including: LED LAMP (plug type), SMD LED (sMD type), LED DISPLAY (digital display type and dot matrix) Type), POWER LED (power type).

Taking a small electronic component such as an SMD LED as an example, since the electrical and spectral characteristics of the finished product are complicated and large, it is usually necessary to pass the measurement and sorting process to different electrical or spectral characteristics. Electronic components are sorted by sorting and collected separately according to grades. Most of these sorting techniques use circular measuring discs, and there are multi-station workstations above the circular measuring disc, including such as polarity reversal and electrical quantity. The workstations for measuring, etc., are arranged in accordance with the electronic components that are sent by the vibrating feeder through the transport channel to the peripheral groove of the circular measuring disc and are intermittently made into the annular flow path, and the direction of the polarity is not consistent with the detection direction, and the direction is adjusted one by one or performed. Measured, and the electronic components that have been measured are usually vacant by the circumference of the circular disk, and are discharged by air pressure and guided by a conveying pipe to a distributor which can selectively distribute the material, and then distributed by the distributor. Collecting the collection boxes corresponding to the pipelines leading to different discharge paths, in the dispenser A detecting device is arranged on the path of the material passing through to detect the material to detect whether the material passes through the distributor and calculate the number of passes of the material.

The applicant has obtained the patent No. M377579 "Small Component Testing Device", which can be used in the aforementioned dispenser to detect whether the material passes through the dispenser. The case is mainly composed of two groups and has a transmission. A receiving state beam detecting module is provided with an detecting device in the interval between the two detecting modules, and a channel smaller than the beam diameter is arranged in the detecting device for the light beam of the detecting module to pass, and the channel guiding method is adopted. The area to be measured is narrowed, and the small component is sensed for passing through the light beam passing through the channel.

Although the patent No. M377579 patent improves the detection accuracy of small materials such as LEDs, small components such as LEDs are easy to generate dust due to collision, friction, etc. during transportation, and small components such as LEDs. When the pipeline is transported to the collection box, it is usually transported by a positive pressure airflow, and the dust is easily accompanied by the airflow entering the detector. The card is stuck in the channel and adheres to the beam detecting module on both sides of the channel, resulting in detection. The accuracy rate is reduced, so it is necessary to stop the machine every time and clean the dust on the beam detection module (about 2~3 times a day), which not only costs people time, but also waits when cleaning. Time (about half an hour of downtime) is also not able to match the long-term machine inspection without interruption.

Accordingly, it is an object of the present invention to provide a dispenser having the function of removing the dust from the detection zone and the detection module.

Another object of the present invention is to provide a dust removing method for reducing the dirt adhesion detection interval and the material detection of the detection module when the material is passed through the flow path.

According to the object of the present invention, when the material is passed by the first-class road, it is detected by the detecting module, and the flow path is a conveying pipe connected to one side of the transfer seat, and the other side of the transfer seat The boring-shaped passage in the detecting section provided by the sliding seat and the one discharging hole in the sliding seat are formed to communicate with each other, and the detecting module is placed at the end side of the detecting section, and the material passing through the flow path is detected; The transfer seat is provided with a gas flow path communicating with the detection section, and the gas is passed through the gas flow path to remove the dust in the detection section.

According to another object of the present invention, the dust removing method for material detection is such that when the material is passed by the first-class road, it is detected by the detecting module, and in the detecting section of the detecting module for detecting the material, the gas is The dust in the detection interval is cleared.

In the dispenser of the embodiment of the invention and the dust removing method for detecting the material, since the dust accumulated in the detecting section between the transmitter and the receiver of the detecting module can be blown off, not only the transmitter and the receiver can be used. The beam detection effect is more accurate, and the operator can also save frequent dust removal and maintenance; in the embodiment of the invention, the operation of the intake pipe to the positive pressure gas can be performed after each material passes the detection interval. It can also be set according to the degree of dust accumulation for a certain period of time or the number of passes of the material. Therefore, there is no need for manual operation to carry out the dust removal operation, which greatly improves the efficiency of the sorting and testing of the distributor, and makes the unit production capacity more costly.
