Abstract

PURPOSE:To enable dislocation correction while current is being applied to a work by providing the device with a chucking section holding the work, a collector ring and with a contact section. CONSTITUTION:A pallet 5 on which a work 4 is rested, is carried in by a carrying section 1, and when it comes up to a specified position, a chucking section 2 is moved to a place where the work 4 is to be held. Next, a roller section 3 is moved up to support the pallet 5 via an electric power supply section 6. By this constitution, the pallet 5 can be freely moved back and forth from side to side over the ball roller section 3. The work 4 is held by the chucking section 2 from the right and left sides, so that dislocation is thereby corrected. Under this condition, since a collector ring 7 is kept brought into contact with a contact section 9 in the lower surface of the pallet at all times where the contact section 9 is connected to the work 4 by a connecting wire 8, the work 4 can thereby be kept energized by the electric power supply section 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work position correcting device used for correcting a work position deviation in a work manufacturing line such as a personal computer, a printer, a television or a video deck.

[0002]

2. Description of the Related Art In a work line for manufacturing a work such as a personal computer, a printer, a television, a VCR, etc., a conventional power supply means for supplying power to the work is to load the work in advance when the work is mounted on a pallet. Position the workpiece on the pallet, or after mounting the workpiece on the pallet, detect the position of the workpiece with an optical camera and correct the displacement by electrical or mechanical control to correct the workpiece on the pallet. By mounting it in a position, the work can be supplied with electric power.

[0003]

The conventional means for supplying electric power to a work in the above-described work manufacturing line has the advantage that after the work is positioned in advance and mounted on the pallet, after the work is mounted on the pallet. Even if the position of the work is detected by the optical camera and the work is mounted at the correct position on the pallet by correcting the position shift by electrical or mechanical control, the cost of the production line is expensive in any case. have. Further, there is also a problem that the specifications of the production line must be changed every time the shape of the work changes.

[0004]

A work position correcting apparatus according to the present invention is capable of moving a pallet on which a work is mounted, a transfer section for transferring the pallet, and a vertical movement of the pallet transferred by the transfer section. And a chucking portion for gripping the work on the pallet supported by the ball roller portion to correct the positional deviation. And a power supply unit for supplying electric power to the work through the rubbing electrons provided on the upper surface of the pallet, and a contact portion corresponding to the rubbing electrons on the lower surface of the pallet, and the work and the contact. The parts are electrically connected.

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

FIG. 1 is a front view showing an embodiment of the present invention.
FIG. 2 is a view showing a state in which the ball roller portion is descending, and FIG. 2 is a front view showing a state in which the ball roller portion is rising in the embodiment of FIG.

In FIGS. 1 and 2, the pallet 5 is
The work 4 is mounted on the upper surface and is transported by the transport unit 1. When the pallet 5 reaches a predetermined position, the chucking unit 2 moves to a position where the work 4 is gripped. next,
The ball roller unit 3 rises and supports the pallet 5 via the power supply unit 6 held on the upper surface thereof. As a result, the pallet 5 is separated from the transport unit 1 and the ball roller unit 3
It is possible to move freely back and forth and left and right.

At this time, the chucking portion 2 holds the work 4 from the left and right, holds the work 4 by the pressure and the frictional force, and corrects the positional deviation. In this state,
Since the contacts 7 provided on the upper surface of the power supply unit 6 are in constant contact with the contact portion 9 provided on the lower surface of the pallet 5, and the contact portion 9 is connected to the work 4 by the connecting wire 8, Power can be continuously supplied from the power supply unit 6 to the work 4.

With this structure, the work 4
Even if the shape is changed or the amount of positional deviation of the mounting position of the work 4 is changed, it is possible to easily correct the positional deviation while supplying power to the work 4.

A large number of pallets 5 are required in the production line of the work 4, but it is not necessary to provide means for determining the mounting position of the work 4 on the pallet 5, so that the price of the pallet 5 is low. Can be one.

Further, the electric power supply unit 6 is provided with the sliding electrons 7, and the pallet 5 is correspondingly provided with the contact unit 9 so that the electric power supply unit 6 can keep the workpiece 4 from moving during the operation of correcting the positional deviation of the work 4. By making it possible to supply power, it becomes possible to automatically supply power without human intervention.

[0012]

As described above, the work position correcting device of the present invention grips the work when the ball roller part that moves up and down by supporting the pallet carrying the work and moves up and down. By providing a chucking part that moves the front, rear, left and right, there is an effect that it is not necessary to provide a means for determining the mounting position of the work on the pallet, and therefore, the price of the pallet is inexpensive. There is an effect that can be. Further, by providing a power supply unit having an electron on the upper surface on the ball roller unit and a contact unit corresponding to the electron on the lower surface of the pallet, the power supply unit can be operated even during the operation of correcting the position deviation of the work. Since the power can be supplied to the work, there is also an effect that the power can be automatically supplied without human intervention.
