Abstract

PURPOSE:To obtain a feeder simultaneously carrying a large number of parts and capable of smoothly feeding the parts without damage one by one and a test apparatus capable of automating positioning and connection to a tester. CONSTITUTION:A feeder is composed of a case 2 with a pair of side plates 3, a plurality of parting plates 6 having intervals 5, by which parts 1 are housed, between the side plates 3 and a bottom plate 7 sliding under the side plates. When the bottom plate is fixed onto a floor face 20 and the case 2 is moved, the parts 1 are dropped one by one and charged into an opening section 32. An opening-closing-able backing plate 34 receives the parts 1. A pair of width narrowing plates 36a, 36b are faced oppositely on both sides of the clearance of a pair of screens 35a, 35b, and the parts 1 are positioned in the cross direction by driving one width narrowing plate 36a. A second cylinder 38 lightly pushes the parts 1 against one 35a of the screens. A plurality of contact pins 39 are brought into contact with the pins 1a of the parts 1 by a third cylinder 40. When the backing plate 34 is opened after a test, the parts 1 are dropped to a lower section, and discharged onto a chute door 44.

FIG. 1 is a front view of a combination device of a supply device and a test device of the embodiment, FIG. 2 is a plan view of the AA arrow of FIG. 1, FIG. 3 is a front view of the supply device of FIG. FIG. 4 is a side view taken along the line BB of FIG. In the figure, those denoted by the same reference numerals have approximately the same function, and duplicate explanation may be omitted.

In FIGS. 1 and 2, a supply device 10 for a component 1 comprises a case 2, side plates 3, wheels 4, a gap 5, a plurality of partition plates 6, a bottom plate 7 and fixing means 8. The specific configuration of the supply device 10 is such that the case 2 provided with the pair of side plates 3 is guided between the rails 21 of the floor surface 20 and moved between the wheels 4 and the side plate 3 which are moved in the arrow P direction by a cylinder or the like (not shown). A plurality of partition plates 6 fixed at intervals to accommodate the flat parts 1 at right angles, a bottom plate 7 that slides horizontally inside the lower part of the side plate 3, and this bottom plate 7 is fixed to the floor surface 20. And a fixing means 8. Details of the supply device 10 will be described later with reference to FIGS. 3 and 4.

In the test apparatus 30 for the component 1, the pedestal 31
The floor surface 20 and rails 21 are formed on the upper surface of the.
The floor surface 20 is provided with an opening 32 for the flat part 1 to be inserted in a posture perpendicular to the horizontal, and a receiving plate 34 that receives the part 1 and can be opened / closed by a cylinder 33 is arranged below the opening 32. It A pair of partitions 35a and 35b are arranged vertically in parallel with each other with a gap between the receiving plate 34 and the opening 32. As shown in FIG. 2, a pair of width-shifting plates 36a and 36b are provided facing each other on both sides of the gap. Position in the width direction. Secondly lightly pressing the component 1 toward the one side 35a of the partition
Cylinders 38 are arranged. A plurality of contact pins 39 that can horizontally contact the pins 1 a of the component 1 are driven by the third cylinder 40. As shown in FIG. 2, the contact pin 39 is connected to the third cylinder 40 by a contact fixing base 41 and electrically connected to a tester (not shown). In addition, the other side 36a of the one side 36a
Reference numeral b is a spring 42 for absorbing the force in the width direction of the component 1. In the case of a micro module, the parts can be inserted through the opening 32.
It is advisable to bring the pin 1a downward. Pin 1a is another I
This is because it is more firmly connected to the printed wiring board and more elastic than parts such as C. The receiving plate 34 may be opened and closed not by horizontal movement but by rotation.

The operation of the test apparatus 30 will be described. When the component 1 is inserted through the opening 32 in a posture perpendicular to the horizontal direction, the component 1 is received by the receiving plate 34 and cannot be fallen down by the pair of partitions 35a, 35b having a gap. Next, if one of the width shifting plates 36a is lightly driven by the first cylinder 37, the component 1 is positioned in the width direction. When the second cylinder 38 is driven in this state, the component 1 is lightly pressed toward the one side 35a of the partition in the thickness direction. At this time, the spring 42 on the other side 36b of the width-shifting plate softens the force in the width direction of the component 1 and does not hinder the resistance to movement in the thickness direction. However,
The component 1 may be positioned with a slight gap provided in the width direction by accurately controlling the movement of one of the width-shifting plates 36a. In this way, the three-dimensional positioning of the component 1 is completed. When the third cylinder 40 is driven, the plurality of contact pins 39 come into contact with the pins 1a of the component 1 and the tester becomes operable. After the test is completed, if the receiving plate 34 is opened by the cylinder 33, the component 1 drops downward and is discharged and conveyed.

Returning to FIGS. 1 and 2 again. A chute door 44 that can be opened and closed by a third cylinder 45 is provided in a part of the chute 43 that is provided below the openable and closable receiving plate 34. The chute door 44 and the chute 4 are provided.
Boxes 46 and 47 are arranged below the tip of 3 respectively,
The component 1 is divided into a good product and a defective product.

The above-mentioned feeding device 10 will be described with reference to FIGS. 3 and 4.
Will be described in detail. The case 2 has a pair of side plates 3, a plurality of partition plates 6 perpendicular to the side plates 3 and a front plate 2a, and has rigidity, and wheels 4 such as so-called free bearings can move freely on the floor. The plurality of partition plates 6 accommodate flat parts 1 at intervals 5 and the tip ends thereof are tapered so that the parts 1 can be conveniently accommodated. A bottom plate 7 that slides horizontally guided by the groove 3a inside the lower portion of the side plate 3 is inserted. The fixing means 8 for fixing the bottom plate 7 to the floor surface 20 is fixed to the floor surface side by driving a hole 8a provided at the end of the bottom plate 7, a rod 8b which can be fitted in this hole, and a cono rod. It is composed of a cylinder 8c. As an exercise device that replaces the wheels 4,
It may be a sliding surface on the lower surface of the case 2, a chain conveyor that suspends the case 2, or a handle that is carried by hand.

The operation of the supply device 10 will be described. If the bottom plate 7 is fixed to the floor surface by the fixing means 8 and the case 2 is moved in the direction of the front plate 2a for each pitch of the partition plate 6, the component 1 that escapes the regulation of the bottom plate 7 at every interval 5 is 1. Each piece falls and is supplied to a specific position such as the opening 32 of the floor surface 20 in FIG. If the bottom plate 7 of the supply device 10 is closed in the direction of the front plate 2a, the component 1 can be housed in the space 5 of the partition plate 6 and transported.

[0020]

According to the parts supply apparatus of the invention 1, if the bottom plate is fixed and the case is moved, the parts are dropped and supplied to a specific position on the floor one by one, and a large number of parts are supplied. There is an effect that the parts can be conveyed simultaneously and smoothly supplied one by one without damage.

According to the component testing apparatus of the second aspect of the invention, the component supplied from the opening is three-dimensionally positioned by the receiving plate, which is a test position, and comes into contact with a plurality of contact pins so that the component can be tested. Therefore, there is an effect that it is discharged after the test is completed and an automatic test can be performed. At this time, as in Invention 3, there is an effect that parts such as a micromodule can be divided into a good product box and a defective product box based on the test result.

According to the component supply device and the test device of the fourth aspect of the invention, there is an effect that a large number of components housed in the case can be automatically supplied from the supply device to the test device to carry out an automatic test and automatically discharged.
