Abstract

PROBLEM TO BE SOLVED: To prevent the affection of dimensional difference of works by a method in which a blade with which works are pushed into the region formed by a pectinated blade and a guide block, is provided, and the blade is independently moved for each work to be fixed. SOLUTION: A work 1 supporting base 10 is provided with suction holes 11 with which the bottom face of the work 1 is fixed by suction, and guide blocks 12 are provided in the vicinity of the suction holes 11. The width direction of the works 1 is positioned by a pectinated blade 2 in such a manner that the works 1 are pressed to the guide blocks 12. The works 1 are pushed into the region formed by the blade 2 and the guide blocks 12 using blades 3, and the works 1 are clamp-fixed. The blades 3 are independetly slid for each work 1 to be fixed. As a resault, the works 1, having excellent attitude stability, can be fixed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an apparatus for fixing a minute work such as a plurality of chip parts.

[0002]

2. Description of the Related Art In a manufacturing process of a chip component, a method of simultaneously processing a plurality of workpieces at the same time in order to increase productivity is adopted. For example, in the step of printing external electrodes on the outer peripheral surface of the chip component, a predetermined external electrode shape is formed by screen printing or the like. However, when printing a plurality of external electrodes as shown in FIG. In order to ensure accuracy, it is necessary to restrict the posture and position of the work by vacuum suction or a clamp mechanism. For this reason, once the individual workpieces are once positioned, the aligned workpieces are collectively clamped and fixed as shown in FIG. 5, or the workpieces are aligned on a holder having a suction port and the bottom side is suction-fixed as shown in FIG. Perform processing.

[0003]

When a plurality of workpieces are clamped together as shown in FIG. 5, some workpieces are not clamped because they do not hit the blade due to the dimensional difference between the workpieces. In addition, if there is a part of the workpiece having a poor posture when the workpieces are aligned, the workpiece is often clamped in an inclined state.

In the holder shown in FIG. 6, the dimensions of the pocket into which the work is dropped must be set in accordance with the size of the work. Therefore, it is necessary to prepare a dedicated holder for each type. The posture stability is improved as the clearance between the work and the pocket is smaller, but it is difficult to drop the work into the pocket. Conversely, the larger the clearance is, the easier the drop is, but the play of the work is increased and the variation in the position of the external electrode is correspondingly increased.

SUMMARY OF THE INVENTION The present invention provides a general-purpose and stable posture fixing device for a plurality of workpieces which is not affected by the dimensional difference between the workpieces and does not require a special jig for different types. The purpose is to provide.

[0006]

According to the present invention, there is provided a base for supporting a work, a comb-tooth plate for pressing the work against a guide block on the base and positioning the work in the width direction of the work,
A blade is provided for pressing and clamping the work into a region formed by the comb-teeth plate and the guide block, and the blade is provided so as to move independently for each work to be fixed and independently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 are main structural views of a work fixing device according to the present invention, FIG. 1 is a plan view, and FIG.
3 is a cross-sectional view as viewed from B. FIG. The work fixing device includes a base 10, a comb plate 2, and a blade 3. The base 10 is provided with suction ports 11 for adsorbing and fixing the work bottom surface, and a guide block 12 is provided near each suction port 11. The comb-tooth plate 2 having the rectangular notch 21 is provided with a linear guide 22 for sliding in the X direction shown in FIG. 1 and a spring 23 in the direction of the guide block 12 as shown by an arrow in FIG. Pressed with. A plurality of workpieces 1 to be fixed are provided with clamping blades 3 for each workpiece, and a linear shaft 31, a detent pin 32 and a spring 33 are individually installed so that each can slide independently. The blade 3 is pushed out toward the comb plate 2 by force as shown by an arrow in FIG.

Next, the drive mechanism of the blade 3 and the comb plate 2 will be described. Air cylinder 4 is rod 41
, The bar 6 is slid, and the end 31a of each linear shaft 31 connected to the bar 6 is pulled out.
To open. The air cylinder 5 slides the comb-tooth plate 2 in the X direction by pushing the rod 51, and separates the notches 21 from the guide blocks 12 to open them.

In the open state, a rectangular area formed by the blade 3, the notch 21 of the comb plate 2, and the guide block 12 is a work fixing area 13.
The suction port 11 exists in the work fixing area 13. The work 1 is installed directly in the work fixing area 13 or, as shown in FIG. 4A, after being set in front of the work fixing area 13 (toward the blade 3), according to the operation procedure described below. Clamp fixed.

The operation will be described with reference to FIG. First, FIG.
A plurality of works 1 placed on the base 10 as shown in FIG.
Work 1 by sliding the blade 3 against
Is pushed into the work fixing area 13. Next, as shown in FIG. 4B, after suction-fixing the bottom surface of the work, the blade 3 is once retracted to release the clamp, and the comb plate 2 is slid toward the guide block 12 so that the work 1 is moved to the comb plate 2.
Positioning in the width direction is performed by being sandwiched between the guide block. Finally, the work 1 is clamped by sliding the blade again toward the work 1 as shown in FIG. At this time, since the blades slide independently of each other, even if the plurality of works 1 to be fixed vary in size, each work 1 is not affected by the size difference.
Is securely clamped.

[0011]

According to the present invention, when a plurality of works such as chip parts are fixed, the work is restrained in both the vertical and horizontal directions while the bottom surface is sucked, so that the work can be fixed with excellent posture stability. . In addition, since the blades 3 slide independently of each other, all the workpieces are securely clamped without being affected by the dimensional difference between the workpieces. Furthermore, as long as the work can be accommodated in the fixing area 13, even if the work has a different length or width, a special jig or the like is not required, and the work fixing mechanism according to the present invention can be applied.
