Abstract

<P>PROBLEM TO BE SOLVED: To quickly develop and provide a means, since there is no effective means capable of coping with necessity, though the necessity is recently caused for moving a chip (chip-shaped various small electronic parts) to the next process by separating the chip by one piece by feeding in one row in an upright attitude as it is. <P>SOLUTION: In a feeder and other chip feeding devices for feeding the chip in one row, the problem is solved by the means provided so as to align the chip in one row in the upright attitude in an upright feeding hole or a feeding groove by forming the vicinity of a tip opening of the feeding hole or the feeding groove for feeding the chip in one row upright in attitude, provided so as to move the chip fed in a row in the upright attitude to the next process by separating the chip by one piece in order from the forefront chip by a proper separating/moving means in the upright attitude as it is and separating the chip by one piece by feeding in a row in the upright attitude. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

The present invention is a feeder or other chip feeding device that feeds one row of chips (chip-shaped various small electronic components, mainly rectangular various small electronic components, for example, chip registers, hereinafter simply referred to as chips). In

The tip of the feed hole or feed groove for feeding a row of chips is formed in an upright state, and the chips are aligned in the upright posture in the upright feed hole or feed groove. Is prepared for

Chips fed in one row in the upright posture are separated one by one from the top tip in an appropriate manner by separating / moving means such as a suction nozzle in the upright posture (take out one), for example, Provided is a means for feeding one row of chips in an upright posture and separating them one by one so as to move to the next process such as chip mounting on a printed circuit board.

Conventionally, some chips, such as a chip register, require that all chips be aligned in the front (or back) direction in order to support the next process.
In that case, in the process of conveying and feeding the chip with a feeder or other chip feeding device, the front and back of the chip are converted and aligned by various posture changing means, and then one chip is taken out in that posture (1 It is widely done to move to the next process
For example, as a conventional chip front / back alignment means, Japanese Patent Application Laid-Open No. 2000-150209 “Chip Front / Back Alignment Transport Device” previously filed by the applicant and inventor of the present application is provided.

Further, as means for leveling not only the front / back surface of the six-sided rectangular chip but also the front / back / left / right surfaces except the front / rear surface, for example, the applicant of the present application, invention Japanese Patent Application Laid-Open No. 2001-163435 “Chip Setting Surface Aligning and Conveying Device” previously filed by the applicant is provided.

However, recently, chips (mainly rectangular chips) are sent in a single row in an upright posture (upright posture with the front and rear surfaces up and down) for the purpose of mounting on a printed circuit board, for example. The need to feed, separate, and move to the next process has arisen, but since there is still no effective means to meet this need, the rapid development and provision has become an issue.
JP 2000-150209 A JP 2001-163435 A

As described above, recently, chips (mainly rectangular chips) need to be fed one row, separated one piece, and moved to the next process in an upright position for the purpose of mounting on a printed circuit board, for example. However, there is still no effective means that can meet this need, so the issue is to develop and provide effective means as soon as possible.

The present invention relates to a chip feeding device that feeds one row of chips,
The tip of the feed hole or feed groove for feeding a row of chips is formed in an upright state, and the chips are aligned in the upright posture in the upright feed hole or feed groove. Is prepared for

The chips that are fed in one row in the upright posture are separated by one means from the top tip in order, and moved to the next process in the upright posture. This solves the problem by means of feeding one row and separating one.

In the present invention, the vicinity of the tip opening portion of the feed holes or feed grooves for feeding the chips in one row is formed in an upright state, so that the chips are placed upright in the upright feed holes or feed grooves. As the chips arranged in a row and fed in one row in the upright posture are separated by one means from the top tip in order, and moved to the next process in the upright posture.
All chips can be perfectly aligned in an upright position, and it is revolutionary that one row of chips in the upright position can be fed, separated, and moved to the next process with extremely high accuracy and high speed. There is a great effect.

Posture conversion stage with feed hole or feed groove to convert tip to upright posture is connected to tip feed device such as feeder with feed hole or feed groove to feed tip horizontally In addition, both the feed holes or feed grooves are communicated,

The posture conversion stage is formed by bending the feeding hole or feeding groove into a U shape, an L shape, etc., so that the vicinity of the opening opening of the feeding hole or feeding groove is formed in an upright state. Means for feeding a single row of chips in an upright posture and separating them one by one in an upright feeding hole or feed groove.

A first embodiment of the present invention will be described with reference to FIG. FIG. 1 is a schematic configuration diagram of Embodiment 1 of the present invention.

Reference numeral t denotes a chip (chip-type workpiece, chip-type small electronic component, eg, chip register), 1 denotes a chip feeding device such as a feeder, 2 denotes a posture changing stage, 3 denotes a feeding hole or feeding groove, 3a denotes An upright feed hole or feed groove in the vicinity of the tip opening is provided as a suction nozzle.

In the present invention, the posture change is provided with a feed hole 3 for changing the posture of the chip t into an upright posture in the tip feed device 1 such as a feeder having a feed hole or feed groove for feeding the tip t in the horizontal direction. The stage 2 is continuously provided, and both the feed holes 3 of 1 and 2 are provided in communication.

The posture conversion stage 2 is configured such that the vicinity of the front end opening 3a of the feed hole 3 is formed in an upright state by bending the feed hole 3 into a U-shape (illustrated example). This is a means for feeding a single row of chips t in an upright posture and separating them one by one in an upright posture.

Thus, the present invention controls the propulsive force of the chip feeding device 1 that feeds one row of the chips t in the feeding holes 3 or the feeding grooves, or feeds the propulsive force and the upright. By balancing with the accumulated weight of a plurality of chips t such as the leading chip t in the hole 3a or the feeding groove,
The leading tip t in the upright feeding hole 3a or feeding groove or the next leading tip t after separating the leading tip t to the outside is temporarily stopped at the set position (see FIG. 1). Is prepared for

As a result, the following chip t is fed by the propulsive force of the chips that are aligned and fed by the chip feeding device 1 (for example, the transport force of the feeder that transports the single-row aligned chips while being pressed). It is intended to control the overflow from the tip opening of the feed hole 3a or the feed groove.

In addition to the temporary stop means described above, the present invention, for example, the leading tip t in the upright feeding hole 3a or feeding groove or the leading leading tip t after separating the leading tip t to the outside. Is temporarily stopped at the set position by the intake force of an intake hole (not shown) provided relative to the position of the tip t or by the insertion / extraction of a stopper pin (not shown).

The present invention, when it is necessary to provide a means for performing the chip in an upright posture / upright state, feeding one row, separating one piece, moving the next process, etc. with extremely high accuracy and high speed, The present invention can be easily applied and general-purpose, and naturally, such a case is also included in the constituent requirements and technical scope of the present invention.

FIG. 1 is a schematic configuration diagram of Embodiment 1 of the present invention.
