Storage card for surface-mounted component, feeder and automatic chip mounter

Abstract

The invention discloses a storage card for a surface-mounted component, a feeder and an automatic chip mounter. The storage card for the surface-mounted component provided by the invention includes a rectangular card having a front surface, a rear surface, a left surface, a right surface, an upper surface and a lower surface, wherein the area of each of the front and rear surfaces is more than that of each of the other four surfaces; the card is provided with a plurality of component bins penetrating through the card and used for accommodating chip components; the cross section of the component bin is polygonal, circular or oval in shape; when the cross section of the component bin is polygonal in shape, the longest diagonal line of the cross section of the component bin is smaller than the body diagonals of the chip components; when the cross section of the component bin is circular or oval in shape, the maximal diameter of the cross section of the component bin is smaller than the body diagonals of the chip components. The storage card is simple in structure, high in package density, compact in volume, low in costs, easy to put in and take out the chip components, and good in popularization prospect.

Description

technical field [0001] The invention relates to an automatic assembling system for chip components, in particular to a memory card, a feeder and an automatic chip mounter for surface chip components. Background technique [0002] The structure of SMD electronic components (hereinafter referred to as "chip components") applied to surface mount mounting is as follows: figure 1 and figure 2 As shown, the chip component 1 usually includes a regular component body 101 and a solderable terminal 102 located at the end of the component body 101 or other parts of the component body 101, through which the chip component can be directly pasted. And welding on the surface of the printed circuit board, not only saves the electrode lead, but also saves the use area of ​​the printed circuit board. At present, such chip components are packaged by tape, that is, the chip components are loaded into a long carrier tape, the carrier tape is wound into a roll, and the chip components in the c...

Problems solved by technology

In addition, since each recessed component magazine in the carrier tape can only accommodate one chip component, and each chip component requires a correspondingly sized recessed component magazine, chip component manufacturers must store a large number of chips. Carrier tapes of different specifications are used to pack chip components of different specifications; and the carrier tape itself has the characteristics of large volume, light weight, and one-time use, which causes the transportation and storage of chip component manufacturers and chip component users. and recycling burden

[0004] In addition, there are also some problems when using traditional carrier tapes for chip component assembly: With the rapid advancement of electronic product miniaturization, printed circuit boards become smaller, and more types and components are installed per unit area of ​​each circuit board. number of components; since each tape feeder can only carry one type of tape, each automatic pick and place machine needs to be equipped with more and more tape feeders

[0006] Of course, there are also some other packaging methods for chip components, such as flat trays and long plastic tubes, which are widely used for packaging and supply. ) Large-size surface mount devices, such as packaged ICs and packaged modules, etc., but this type of packaging method is not suitable for packaging a large number of small-size chip components
