Embodiment Construction

[0030] For the features and effects of the present invention described above or not described, reference will be made to Figure 3 to Figure 5 Embodiments of the present invention will be described in detail.

[0031] Such as image 3 As shown, the non-contact vacuum pad of the present invention is indicated by reference numeral 10 . The vacuum pad 10 includes: a body 11 ; a flow guide member 12 combined with the lower part of the body 11 ; and a compressed air discharge channel formed between the body 11 and the flow guide member 12 . Here, the above-mentioned body 11 includes: a compressed air supply hole 13 formed at the center of the body 11 ; and an outward diffusion surface 14 formed at the lower end of the above-mentioned supply hole 13 . This part does not differ from the prior art. However, the above-mentioned outward diffusing surface can be selected as an inclined surface or an annular surface.

[0032] The flow guiding member 12 does not protrude along the lowe...

Abstract

The present invention relates to a non-contact type vacuum pad which is used for holding articles in a vacuum conveying system. The vacuum pad of the present invention comprises a main body, an air guide, and a discharge pathway formed by means of the main body and guide. The air guide is attached in such a way that it does not project from the bottom edge of the main body, and it has: a central inflow recess communicating with a supply hole; one or more flow pathways formed passing through the wall surface from the inflow recess; and a suction hole which extends from the bottom surface and connects to the flow pathway(s). When compressed air passes through the flow pathway(s), the outside air underneath the vacuum pad passes the vicinity of a diffusing surface and through the suction hole and is entrained into the compressed air, and merges with and is discharged together with the compressed air. At this time, articles can be strongly held due to the negative pressure produced in thespace between the vacuum pad and the article.

Description

technical field [0001] The invention relates to a vacuum pad, which is used in a vacuum transfer system to play the role of adsorbing articles, in particular, relates to a non-contact vacuum pad capable of adsorbing articles in a non-contact state. Background technique [0002] The so-called "vacuum transfer system" refers to a system that creates a negative pressure in the vacuum pad through the action of compressed air, and then uses the formed negative pressure to absorb items and transfer them to a designated location. A contact vacuum pad is commonly used in this system. However, the vacuum pad of this type is in direct contact with the surface of the object, so it is easy to cause damage or pollution to the surface of the object. [0003] In particular, panels used for displays of electronic products are very sensitive to small scratches, deformations, and foreign objects, so it is not suitable to use the above-mentioned contact pads during transfer. Thus, the demand ...
