Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyance positioning device for accurately stopping objects conveyed on a conveyor at a desired position, and it is an object of the present invention to provide a device suitable for automatic inspection, etc. purpose.

For example, let's take a factory that manufactures television receivers as an example.

Once assembled, the television receiver needs to be tested to see if it passes the complete standards.

When inspecting withstand voltage and insulation resistance, it is necessary to touch the inspection machine to metal parts such as screws exposed on the surface of the television receiver, and in order to make the work more efficient, this inspection work is not done by machine. Automation is preferred.

To this end, the problem is how to accurately stop the television receiver, which is carried on a pallet on a conveyor, at a certain position where an inspection machine is installed.

This is because, for example, the diameter of the head of a screw exposed on the surface of the television receiver to be inspected is approximately 5 mm, and the contact of the inspection machine is also thin. Inspection cannot be performed automatically unless the receiver is stopped at a desired position.

The present invention provides a device that satisfies the above requirements, and one embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a pallet 4 is conveyed on a conveyor 13.

A television receiver 12, which is an object to be inspected, is placed on the pallet 4 and moves in the direction of arrow A together with the pallet 4.

When the tip of the pallet 4 comes into contact with the protruding stopper 1, the pallet 4 stops moving.

A front view of this state is shown in FIG.

As a result, the position of the television receiver 12 in the transport direction is determined.

Next, the softer 3 located under the pallet 4 rises,
The pallet 4 is pushed up, and the pallet 4 stops when the upper surface of the pallet 4 comes into contact with the position regulating part 2.

A side view of this state is shown in FIG. This determines the position of the television receiver 12 in the height direction.

Next, a pair of rods 5 protrude from a direction perpendicular to the conveying direction of the conveyor 13, come into contact with one surface of the television receiver 12, and further protrude to move the television receiver 12 on the pallet 4.

Since a positioning plate 6 protrudes from a position opposite to the rod 5, the television receiver 12 stops when the other side comes into contact with the positioning plate 6.

This state is shown in FIG. This allows the television receiver 12 to be parallel to the conveyor 13.

With the above steps, the position of the television receiver 12 in the three directions of X, Y, and Z has been determined.

However, in this state, the relative positions of the inspection device 9 and the television receiver 12 have not been determined.

The inspection base 8 is provided with an inspection device 9 and a movable positioning arm 7.

The inspection base 8 can be moved parallel to the conveyor 13 by a cylinder 11 via a cam 10.

The arm 7 stands vertically so as not to interfere with the conveyance of the television receiver 12, but when the television receiver 12 is positioned at a predetermined position as described above,
This arm 7 rotates in the direction of arrow B and is positioned so that its tip faces the side surface of the television receiver 12.

Simultaneously with the rotation of the arm 7, the inspection base 8 starts moving in the direction of arrow C by driving the cylinder 11.

When the inspection base 8 moves and the tip of the arm 7 comes into contact with the side surface of the television receiver 12, the limit switch 14 provided at the tip of the arm 7 is pressed and activated, and the cylinder 11 is driven. to stop.

Therefore, the movement of the inspection base 8 is also stopped. The above inspection base 8
An inspection device 9 is integrally installed in the G. Therefore, the relative positions of the television receiver 12 and the inspection device 9 via the arm 7 have been determined.

This state is shown in FIG. In this state, a contactor extends from the inspection device 9 and comes into contact with an object to be inspected, such as a screw of the television receiver 12, so that insulation resistance, breakdown voltage, etc. can be inspected.

After the inspection is completed, the inspection device 9 and the arm 7 return to their horizontal positions so as not to prevent the television receiver 12 from being transported to the next process.

In the above explanation, one inspection device 9 has been described, but it goes without saying that another inspection device 9a and arm 7a may be provided at a position opposite to the inspection device 9.

For objects to be inspected, such as television receivers, which vary in design and size depending on the model, the arm described above is extremely effective because it can detect the position simply by contacting the outer surface of the object.

Furthermore, since the arm is provided with a limit switch, the arm will not push the television receiver with more force than necessary, thereby preventing damage.

If a detecting body such as an arm is not used, it would be necessary to provide a hole for positioning in any model of television receiver, but such a hole would spoil the design. Actually it's not possible.

As described above, according to the present invention, after accurately positioning the object to be inspected conveyed on the conveyor, the arm searches for the position of the object to be inspected, and the arm is used to locate the object to be inspected and the object to be inspected. Since the relative positional relationship with the device can be determined, it is useful for automating inspections.
