Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a holding device for attaching and holding an object to be processed. In particular, the present invention relates to a device that clamps and holds a flat object to be processed from both left and right sides and can reliably clamp the object regardless of the size of the object.

[0002]

[Prior Art]

 As shown in FIG. 4, a flat object W such as a printed circuit board is attached to the transfer rod 7 or the like via the holding jig 100 and dipped in the treatment liquid Q in each surface treatment apparatus. In addition, many are configured to perform processing while supplying power as needed. The conventional structure of the holding jig 100 is generally composed of a base body 10, a clamper 20, a support mechanism 30, a clamping force applying mechanism 50, and an unclamping force applying means 40, as shown in FIG. Target.

That is, the base body 10 is attached to the carrier rod 7 via the suspending tool 15. The clamper 20 includes one holding claw 21 and the other holding claw 25, and is supported by the support mechanism 30 so as to be capable of clamping / unclamping operation. The support mechanism 30 is formed by pivotally connecting a pair of brackets 31 and 35 with a pin 32. In this example, the other holding pin 25 is tilted with respect to the one holding pin 21 on the stationary side. Then, the two sandwiching portions 22 and 26 are supported so as to be spaced apart from each other. The clamping force applying mechanism 50 is composed of a pair of overlapping straight leaf springs 51 and 55, and is always applied with the clamping force. The unclamping force applying means 40 for applying the external force (unclamping force) F releases the clamping force, and is composed of the operation lever (40) connected to the other holding claw 25 via the other bracket 35. There is. In addition, 23 in FIG. 5 is a power feeding part.

Therefore, an external force F is applied to the operating lever (40) to release both of the sandwiching claws 21, 25 (22, 26), and the workpiece W is placed in contact with the side surface 21S of the one sandwiching claw 21. Then, the external force F is removed. Then, the clamping force applying mechanism 50 (51, 55) operates, and the holding claw 25 rotates around the pin 32 of the support mechanism 30. As a result, the upper portion of the workpiece W is clamped by the sandwiching portions 22 and 26 by the urging force of the springs 51 and 55.

After that, the workpiece W can be suspended from the upper portion and immersed in the treatment liquid Q by transporting and lifting the transport rod 7 with a crane or the like, as shown in FIG.

[0006]

[Problems to be solved by the device]

 However, the above-mentioned conventional structure has the following problems, and its solution is strongly desired.

That is, as the sizes of the objects W to be processed become various due to diversification, the holding jigs 100 arranged in rows on the transport rod 7 to accommodate large (small) objects are small (large) objects. Not only is it difficult to hold the processed material W and its applicability is small, but also automation of clamping / unclamping is difficult.

The workpiece W is clamped at the upper part by a holding jig 100 and hung on the carrier rod 7, and a support mechanism 30 forming the holding jig 100 rotates a pair of brackets 31, 35 with a pin 32. Since the structure is dynamically connected, it becomes a liquid pool and the amount of retained liquid increases. Further, a liquid pool is also formed at a portion where the object W to be processed is clamped by the two holding claws 21, 25 (22, 26). Therefore, when the object W to be processed is lifted from the processing liquid Q, dripping occurs on the surface of the object W to be processed, and the film is formed into two layers. This causes serious problems such as poor development, poor etching, and low resolution during exposure when the printed circuit board is subjected to electrodeposition resist processing.

When the object W to be processed has a large size, the upper part of the object W is clamped and hung, so that a shake easily occurs. Therefore, automatic transfer is difficult and stable treatment cannot be performed in the treatment liquid Q.

On the other hand, when the object W to be processed is extremely thin, for example, 0.2 mm in thickness, the clamp point is small, so that the object cannot be reliably held and the clamp force is excessively deformed.

Depending on the thickness and size of the workpiece W, the holding jig 100 must be replaced. This is because the workpiece W is clamped with one surface as a reference, so that the relative positions of, for example, electrodes in the processing tank change.

Here, the object of the present invention is to hold an object to be processed which has a wide applicability and can reliably hold the object regardless of size and thickness of the object to be processed and can produce a high quality product in which dripping is prevented. To provide equipment.

[0013]

[Means for Solving the Problems]

 The apparatus for holding an object to be processed according to the present invention is mounted on the hanger by aligning it with a hanger formed so as to be conveyed by a transfer mechanism and a vertical reference line on which a plate-shaped object is attached and held. The vertical frame, a pair of upper and lower horizontal frames laterally displaced from the vertical reference line, a movable vertical frame slidably attached to the horizontal frames along the longitudinal direction thereof, and the fixed vertical frame. And a plurality of holding jigs correspondingly attached to the movable vertical frame on the vertical reference line and capable of clamping and unclamping one side of each of the objects to be processed.

[0014]

[Action]

 In the present invention having the above-mentioned configuration, the left and right sides of the holding jig are clamped by the plurality of holding jigs attached to the fixed vertical frame and the movable vertical frame, so that a thin object can be reliably and stably clamped. In addition, automatic transportation becomes easy, and large workpieces do not shake. Moreover, since it is clamped on both the left and right sides and from the horizontal direction, liquid dripping when lifted from the processing liquid can be prevented and high quality processing can be performed regardless of the type of holding jig. Further, when the size of the object to be processed is changed, the movable vertical frame can be slid on the upper and lower horizontal frames to adjust the distance between the movable vertical frame and the fixed vertical frame so that the clamp can be reliably performed regardless of the size. However, since multiple vertical holding jigs are attached to both vertical frames, the position in the processing liquid can be adjusted even if the hanger is in a fixed posture. Furthermore, the upper and lower horizontal frames are laterally displaced from the vertical reference line that holds the object to be processed, so that impurities falling from the sliding part do not adhere to the surface of the object to be lifted. ..

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 3, this holding device includes a hanger 1, a fixed vertical frame 11, a pair of upper and lower horizontal frames 25 and 26, a movable vertical frame 15, and a plurality of holding frames which are attached to the vertical frames 11 and 15, respectively. The jig 100 is formed so that it can be clamped at multiple points from the left and right sides of the workpiece W and the distance between the movable vertical frame 15 and the fixed vertical frame 11 can be adjusted.

The object W to be processed in this embodiment is a flat printed circuit board, and the processing is electrodeposition register processing.

In FIG. 1, the hanger 1 is formed so as to be carried by being locked by a carrying mechanism. In this sense, it is the same as the above-mentioned conventional transport rod 7. That is, the form of the hanger 1 is not limited to the disclosed example.

Next, the vertical frame structure 10 is composed of a fixed vertical frame 11 and a movable vertical frame 15, and a vertical reference line Z (which is shown as a reference plane in FIGS. 2 and 3) for holding the workpiece W 1. The above is used for mounting a plurality of holding jigs 100 on the top.

First, the fixed vertical frame 11 is designed to directly attach the holding jig 100. For this reason, it is fixed to a locking member 12 that projects from the hanger 1 in the horizontal direction. Therefore, the fixed vertical frame 11 always coincides with the vertical reference line Z. On the other hand, the movable vertical frame 15 is slidably mounted on a pair of upper and lower horizontal frames 25, 26 which are laterally displaced from the vertical reference line Z as shown in FIG. For this reason, each holding jig 100 is formed to be attached via each positioning member 17.

The upper horizontal frame 25 is directly provided on the lower portion of the hanger 1 in this embodiment. The lower horizontal frame 26 is provided over the lower end of the fixed vertical frame 11 via the horizontal member 16. Both lateral frames 25, 26 are round shafts.

The movable vertical frame 15 is slidably attached to the upper and lower horizontal frames 25 and 26 via bushes 35 and 36 forming a slider 30. As shown in FIG. 3, each bush 35, 36 is provided with a stopper 45 (45) that engages with a recess 46 (46) spaced apart from the upper (lower) horizontal frame 25 (26). This is to ensure that the adjusted space between the movable vertical frame 15 and the fixed vertical frame 11 is maintained.

Next, the holding jig 100 is formed to perform an unclamping operation by applying an external force to the lever 41 shown in FIG. 3 and a clamping operation if the external force is removed. The holding jig 100 shown in FIG. 5 is attached to each of the vertical frames 11 and 15 in a horizontal orientation so as to clamp the workpiece W from the horizontal direction. Further, in this embodiment, the object W to be processed is automatically attached and detached by an automatic clamp / unclamp device which is arranged at an appropriate position outside the processing liquid Q. In addition, the model and form of the holding jig 100 are not questioned. The point is that it is only necessary to clamp both the left and right sides of the object W to be processed in the horizontal direction. That is, when the object W to be processed is lifted from the processing liquid Q, it is sufficient to prevent liquid dripping.

Next, the operation of this embodiment will be described. First, consider the case of processing the large object W1 shown in FIG. In a suitable place, the movable vertical frame 15 is fixed to the upper and lower horizontal frames 25, 26 at a position shown by a solid line in FIG. Then, after adjusting the relative position between the hanger 1 and the workpiece W1, and then removing the external force from the bar 41 of each holding jig 100, the left and right sides of the workpiece W1 can be instantly changed at multiple points. Can be clamped. The workpiece W1 in this case is held on the vertical reference line (plane) Z.

Thus, the hanger 1 is moved by the transport mechanism, and the object to be processed W1 is immersed in the treatment liquid Q to perform the electrodeposition resist treatment. Since the workpiece W1 is held at multiple points on both sides, the posture is stable and good processing is performed. There is no effect even with a very thin object (W1). In addition, the clamping force is stable and multi-point power supply is used, so high-quality processing is possible.

After the treatment, the hanger 1 is lifted. Even if a small amount of liquid drips from each holding jig 100, it does not adhere to the processed surface of the object W1 to be processed, so that the formation of two layers can be completely prevented. After that, unclamping may be performed in place by the reverse procedure to the above.

Next, it is assumed that the small workpiece W2 is processed. At a proper position, the upper and lower stoppers 45 are released, the bushes 35 and 36 are made free, and the movable vertical frame 15 is slid along the upper and lower horizontal frames 25 and 26, and is moved to the position shown by the chain double-dashed line in FIG. When the distance from the fixed vertical frame 11 reaches a desired value, stop and operate the stoppers 45, 45 to fix.

After that, the object to be processed W2 may be clamped as in the previous case. In this embodiment, the two holding jigs 100 on the lower tier attached to both the vertical frames 11 and 15 are used for clamping, but at which position the holding jig 100 is clamped. It may be used and clamped.

Therefore, according to this embodiment, the hanger 1, the fixed vertical frame 11, the pair of upper and lower horizontal frames 25 and 26, the movable vertical frame 15, and the vertical frames 11 and 15 on the vertical reference line (plane) Z. It is composed of a plurality of holding jigs 100 for holding the object to be processed W, and is formed so that the object to be processed W (W1, W2) is clamped from both left and right sides at multiple points and the intervals of the clamp holding points can be adjusted. Therefore, regardless of the size and thickness of the object to be processed W, it can be reliably held, liquid dripping can be prevented, high quality products can be produced, and the applicability is wide.

Further, since a plurality of corresponding holding jigs 100 are mounted on both vertical frames 11 and 15, even a thin object can be stably held by the multipoint clamp, and power can be smoothly fed.

Further, since the horizontal frames 25 and 26 are laterally displaced from the vertical reference line Z, there is no fear of dropping any foreign matter on the surface of the workpiece W.

Further, since the structure is simple, the cost can be significantly reduced.

Furthermore, since the holding jig 100 is a horizontal clamp, the design of the holding jig 100 is easy, the burden of reducing the liquid pool is small, and the manufacturing is possible at low cost.

[Effect of the device]

 According to the present invention, a hanger, a fixed vertical frame, a pair of upper and lower horizontal frames, a movable vertical frame, and a plurality of holding jigs for holding an object to be processed on the vertical reference line (plane) on both vertical frames, Since the object to be processed is clamped from both the left and right sides at multiple points and the intervals between the clamp points can be adjusted, the following excellent effects are achieved. Since the distance between the vertical frames, that is, the distance between the holding jigs on both sides can be adjusted, reliable clamping can be performed regardless of the size of the object to be processed, and the applicability is wide and the automation is easy. Since the object to be processed is clamped from both the left and right sides, it is possible to prevent double layering due to liquid dripping and perform high quality processing. Since the object to be processed is clamped at multiple points on both the left and right sides, it is possible to reliably hold the clamp even with an extremely thin object, and to perform stable power supply and stable transfer. Since it is not a suspension method on the upper part, it is possible to completely prevent vibration during transportation and processing regardless of the size of the object to be processed. Since the holding jig needs only to be clamped from the horizontal direction, the degree of freedom of its structure is wide, and it is possible to reduce the cost without having to excessively design the liquid pool. Since the sliding guide portion of the movable vertical frame, that is, the pair of upper and lower horizontal frames is displaced laterally from the vertical reference line, foreign matter does not drop onto the object to be processed.
