Abstract

The subject of the invention is to provide a vacuum suction system capable of stably charging a workpiece into a workpiece storing hole of a workpiece carrying table and discharging the workpiece. This system is provided with the workpiece carrying table 2 having the workpiece storing hole 5 and a table base 3 having a vacuum suction groove 7 communicated with the workpiece storing hole 5 of the workpiece carrying table 2. The workpiece storing hole 5 and the vacuum suction groove 7 are communicated with a vacuum generation source 17 via a vacuum pipe 9. A negative pressure sensor 10 is connected to the vacuum pipe 9. Based on a signal from the negative pressure sensor 10, compressed air from a compressed air generation source 20 is delivered to the vacuum pipe 9, or the inside of the vacuum pipe 9 is opened to the atmosphere to regulate a degree of vacuum in the vacuum pipe 9.

Description

technical field [0001] The present invention relates to a vacuum suction system for sucking workpieces of chip components, which are electronic components, into workpiece storage holes of a conveying table. Background technique [0002] according to Figure 8 ~ Figure 10 , to describe a conventional vacuum suction system that sucks a workpiece into a workpiece storage hole of a conveyance table. [0003] in, Figure 8 It is a partial vertical sectional view showing an example of applying a conventional vacuum suction system to a conveyance table, and FIG. 9 is Figure 8 The piping diagram of the vacuum suction system shown, Figure 10 This is a timing chart illustrating the relationship between the workpiece filling rate and the degree of vacuum. [0004] Figure 8 Among them, the conveying table 2 is rotatably provided on a table base 3, and the table base 3 is fixedly provided on a base 4. A plurality of workpiece storage holes 5 are provided in a ring shape through t...
