BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate transfer device suitable for transferring a plate such as a printed circuit board to a plating tank or the like.

[0002]

2. Description of the Related Art Conventionally, when a printed circuit board is transferred from a previous process to a next plating process in its manufacturing process, for example, a plurality of printed circuit boards arranged in parallel on a horizontal moving means is operated by an operator. The pliers were moved to the lower side, and the pliers were picked up by the pliers and further transferred to the plating tank.

[0003]

In the above-mentioned prior art, when performing a total transfer control for picking up a plate such as a printed circuit board that has been conveyed from a previous process location and moving it to a next process location such as a plating tank. However, as described above, all of them rely on the manual work of the operator, so that there is a drawback that it takes time and labor costs increase.

The present invention has been made on the basis of such a background, and a plate transfer device capable of shortening time and cost by performing plate transfer control fully automatically. The purpose is to provide.

[0005]

In order to achieve the above-mentioned object, the present invention proposes that the plates are arranged in parallel on the surface,
A conveyor unit provided with an endless belt driven by a motor, and a plate holding unit provided with a clip device capable of vertical movement and horizontal movement, which holds a plate at least in an arc-shaped portion of the endless belt and horizontally conveys it to the next process. It is characterized by having.

[0006]

The control means including the CPU lowers the clip device and the guide device with respect to the plate which is conveyed by the belt conveyor unit and stops at a predetermined position, and guides the plate to the clip device by the guide device to hold the plate. , The plate is lifted to the original position and horizontally moved together with the plate hanger.

[0007]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a schematic side view of a plate transfer device according to an embodiment of the present invention, showing a plate 7 held upright by a belt conveyor unit 1 and held by a plate holding unit 100. Has been done.

FIG. 2 is a perspective view of a plate transfer device.

First, the belt conveyor unit 1 is stretched between a driving side cylinder and a driven side cylinder (only one cylinder 11 is shown in the drawing) and rotates in a predetermined direction.
Have two. On the surface of the endless belt 12, a large number of thin pieces 121 are formed so as to project in parallel with the belt width direction, so that a channel 122 is formed between the thin pieces 121, 121. The plate 7 is press-fitted into the channel 122 and held upright.

On the other hand, the plate gripping unit 100 shown in FIG. 2 or individually enlarged and shown in FIG. 4 is arranged above the belt conveyor unit 1, and has a plurality of clip devices 2, a plurality of guide devices 3, and a vertical movement. It is composed of an apparatus 4, a plate hanger 5, a support frame 6, and the like.

In the clip device 2, the central portions of the front arm 211 and the rear arm 212 are pivotally connected at a fulcrum 213, and a pliers 21 having a spring (coil spring) 214 interposed above the fulcrum 213, an air cylinder 22, Has 23. The spring 214 urges the pliers 21 in the closing direction, that is, in the direction in which the lower ends of the front arm 211 and the rear arm 212 (portions holding the plate 7) come into contact with each other, while the air cylinders 22, 23 are urged. At the time of its operation, the pliers 21 are opened by acting on the arm 211 and the rear arm 212 from the outside at the upper ends thereof against the biasing force of the spring 214 in the closing direction.

FIG. 3 is an explanatory view of a state in which the plate 7 conveyed by the belt conveyor unit 1 is gripped by the plate gripping unit 100 at a predetermined position. Based on this drawing, the action of the air cylinders 22 and 23 is shown. More specifically, the air cylinder 22 includes the front arm 2
The upper part of 11 is pressed from the outside to open the pliers 21, and the air cylinder 23 operates to support the upper part of the rear arm 212. This air cylinder 22,23
Is mounted to the support frame 6, but its mounting position is preferably as far above the spring 214 as possible to reduce the force required to open the pliers 21 against the spring 214.

The guide device 3 has a pair of guide pieces 31 each having a taper 4 having a divergent shape at the lower end and an upper end locked to the support frame 6, and the plate 7 by the guide pieces 31.
And a photo sensor 32 for detecting that the vehicle has been guided. In addition, the photo sensor 32 is used in the pliers 21.
The guide piece 31 above the point where the plate 7 grips the plate 7.
Plates mounted on the side and of different heights 7
Is accurately guided by the guide device 3, in other words, accurately guided by the open pliers 21,
The pliers 21 securely hold the plate 7.

The vertical moving device 4 is composed of a combination of a guide screw and a nut, and is provided on both sides of the support frame 6 (FIG. 5). Then, the support frame 6 is moved up and down by rotating the guide screw by a motor (not shown). As the vertical moving device, other various mechanisms such as a chain and a chain wheel can be adopted.

The plate hanger 5 fixes the tip of the rear arm 212 of the pliers 21 and uses an elevating slide frame (not shown) for plating to plate 7
Pliers 21 for holding the plating tank (not shown))
It is designed to move up to. The pliers 21 are connected to a power source to form electrodes when the plate 7 is plated.

The support frame 6 supports the above-mentioned clip device 2, guide device 3, plate hanger 5, and the like.

Next, the control operation will be described.

As shown in FIG. 3, the plate 7 erected and conveyed by the belt conveyor unit 1 is stopped near the highest point of the slanted endless belt 12 (therefore, it is also an arcuate portion which contacts the cylinder 11). It At this point, the plate gripping device 100 descends toward the plate 7, guides the plate 7 by the pair of guide pieces 31 of the guide device 3, and the guide piece 31 and the air cylinders 22, 23.
And is moved relatively into the open pliers 21 under the action of. Although the endless belt 12 does not have to be inclined, the position where the plate 7 is locked and gripped by the pliers 21 is preferably an arcuate portion of the endless belt 12. This is because the adjacent plates 7 are separated from each other in the case of the arcuate portion and are easily gripped by the pliers 21.

When the plate 7 is inserted to a position where it can be sufficiently gripped by the pliers 21, the photo sensor 32
Detects the plate 7 and outputs a detection signal. In response to the output of this detection signal, an operation stop command for the air cylinders 22 and 23 is issued. As a result, the pliers 21 are
The plate 7 is closed by the action of No. 4 and is held by the pliers 21. And the plate gripping unit 1
00 back to the original position, and as shown in FIG.
Is raised from the solid line position to the two-dot chain line position. Next, the belt conveyor unit 1 is operated again, the subsequent plate 7 is conveyed to the above-mentioned plate stop and grip position, and the same operation is repeated thereafter.

When the plate 7 is gripped by all of the clip devices 2 provided in the plate gripping unit 100, the plate 7 is horizontally moved together with the plate hanger 5 and the clip device 2 by a means (not shown), and the next step, for example, It is transported to the plating tank. The control means that controls the above-described control operation is composed of a CPU (not shown).

[0022]

As described above, according to the present invention, the plate conveyed by the belt conveyor unit from the pretreatment unit is automatically stopped at a predetermined position, and at that time, the clip device of the plate gripping unit is stopped. Automatically lowers to hold the plate, raises it to the original position again, and then automatically moves it horizontally to convey it to the next process processing unit, so it does not bother the operator and quickly. In addition, the plate can be accurately transferred, and the labor cost can be reduced.
