Description

[Detailed Description of the Invention] (Industrial field of application) The present invention uses a jig capable of mounting a plurality of plate-shaped or film-shaped objects in the horizontal direction and simultaneously making a plurality of steps in the vertical direction. Related to surface treatment equipment for surface treatment,
In particular, the present invention relates to a jig and a clamp member for carrying processing.

(Prior Art) Generally, for transporting and holding an object to be processed in a surface treatment apparatus for performing surface treatment such as electroplating or other electrolytic treatment on a plate-shaped material such as a printed circuit board or chemical plating or other electroless treatment. The transfer processing jig is used for.

As an example of a conventional transfer processing jig, one shown in FIG. 8 is known. In the figure, the jig for carrying processing has an object carrying rod 10, a frame 11 hung from the object carrying rod 10, and the object carrying rod having an appropriate interval. Clip 12 fixedly attached and the lower end side rod 11 of the frame 11
A plurality of lower clamp parts 13 arranged at a predetermined interval in a
It has and.

The object to be processed A is further fixed in a space surrounded by the non-processing object conveying rod 10 and the frame 11 by the clip 12 and the lower clamp 13.

Further, as the non-processed object A that can be clamped in two steps, for example, as shown in FIGS. 9 to 11, the vertical frames 1 and 1 and the vertical frame 1 are attached via a bracket 2 so that they can be moved and held. The plurality of horizontal frames 3 and 3, the contacts 4 using springs for holding the object to be processed in the horizontal frame 3 at predetermined intervals, and the frame body is hung on the carrying rod and electrically connected. Hook 5
Etc. Here, the bracket 2 is fixed to the vertical frame 1 with screws 6.

In the clamp jig having such a configuration, the object to be processed H is energized and held by the contacts 4 arranged at predetermined intervals on the horizontal frame 3.

(Problems to be Solved by the Invention) By the way, in the case of the above-described conventional clamp jig, in the example shown in FIG. 8, the object to be processed could be attached only in one stage. Therefore, the production efficiency per installation area of the processing device is poor. Further, in the case of the jigs shown in FIGS. 9 to 11, since the object to be processed is held only by the clamping force of the spring of the contact 4, it is possible to cope with the change in the plate thickness of the object to be processed such as a printed circuit board. It was not possible, and there was a problem in terms of mounting accuracy. Furthermore, it was not possible to obtain a stable clamping force due to the change in plate thickness.

Furthermore, since the bracket 2 is fixed and held by the manual screw 6, there is a problem in automation.

The object of the present invention was made in view of the above-mentioned drawbacks,
It is an object of the present invention to provide a jig for carrying processing which can obtain a stable clamping force against a change in the plate thickness of an object to be processed and can improve the production efficiency per installation area.

(Means for Solving the Problem) A conveyance processing jig according to the present invention comprises left and right vertical frames, a plurality of horizontal frames, and brackets provided at both ends of the horizontal frames and engageable with the vertical frames. The horizontal frame is composed of clamp members arranged at predetermined intervals, and the clamp member clamps the top and bottom of the object to be processed and allows the object to be conveyed and held in a plurality of stages. Also, a clamp element having a plurality of concave and convex portions at its tip, a lever for rotating the clamp element around an axis, and a lever which is wound around a rotation shaft of the lever presses the clamp member via a pin. A clamp member includes a spring member that biases in a direction, a support portion that is arranged to face the clamp element, and a clamp screw, and the clamp element clamps and conveys an object to be processed.

(Operation) As described above, since the transfer processing jig according to the present invention is provided with the plurality of horizontal frames, it is possible to install the objects to be processed in a plurality of stages and improve the production efficiency. You can Also, the clamp part can be easily opened and closed by an external auxiliary drive, and the brackets attached to both ends of the horizontal frame can be easily held and moved by an external auxiliary drive.
It can be automatically attached and detached. Therefore, it is possible to greatly contribute to the automation of attachment and detachment of the object to be processed.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a front view of a clamp member showing an embodiment of a transfer processing jig of the present invention, and FIG. 2 is a sectional view taken along the line AA. In both figures, the clamp member includes a clamp element 20 having a plurality of concave and convex portions 20a at its tip, and the clamp element 20 having a shaft 2
A lever 22 that rotates about 1 and a rotation shaft 23 of the lever 22
A spring 25 which is wound around the lever 22 and urges the lever 22 in a direction to press the clamp element via a pin 24, a support portion 26 and a clamp screw 27 which are arranged to face the clamp element 20.
Etc.

Here, the clamping element 20 comprises a shaft 21 inserted through the support 26.
It is rotatably supported by the lever 22 in the slot 20b.
A pin 24 provided at the tip of the is loosely fitted. lever
22 is rotatably supported by a rotating shaft 23 and is also a spring.
Energized at 25. The support portion 26 supports the clamp element 20 and the lever 22 so as to be semi-rotatably supported, and the central portion faces the clamp element 20 to hold an object to be processed.

The transfer processing jig configured as described above is fixed to the horizontal frame 28 with screws 27 at appropriate intervals.

FIG. 5 is a partially cutaway front view showing the bracket portion of the present invention, FIG. 6 is a plan view showing the bracket portion, and FIG. 7 is a side view showing the bracket portion.

In the figure, the bracket portion is a square hole into which the vertical frame 29 is inserted.
30 and a lever 32 that is rotatably supported by a shaft 31 and a leaf spring that biases the lever 32 so that the tip of the lever projects into the square hole 30.
It is composed of 33 mag. Therefore, by operating the lever 32 by external driving, the horizontal frame can be attached to the vertical frame with one touch.

FIG. 3 and FIG. 4 are a front view and a side view of a transfer processing jig provided with the above-described clamp member. In this embodiment, the horizontal frame 28 is attached to the vertical frame 29 by the bracket A which can be held and moved by one touch by external driving. After that, the object to be processed is clamped by the conveyance processing jigs arranged on the horizontal frame 28 at appropriate intervals. In the above embodiment, since the object to be processed is sandwiched in two stages, the production efficiency can be improved. Furthermore, since the clamp member is configured in two stages, it is possible to obtain a stable clamping force even when the plate thickness changes.

(Effect of the Invention) As described in detail above, according to the transfer processing jig and the clamp member according to the present invention, a stable clamping force can be obtained even for an object to be processed having a different plate thickness. It is also optimal for automating the attachment / detachment of the object to be processed. Further, according to the transfer processing jig of the present invention, it is possible to install a plurality of stages of objects to be processed in the surface processing apparatus, and it is possible to improve the production efficiency.
