Abstract

PURPOSE:To apply a power source and a test signal automatically to an electric appliance on a pallet, by providing a sliding means applying a signal to the electric appliance and a support means adapted to support the sliding means rotatably in the direction of moving the pallet. CONSTITUTION:As a pallet 3 moves over a conveying line 1 from the left to right, a male member 25 is automatically inserted between female members 11. With the further movement of the pallet 3 to the right, a slider 5 turns clockwise against an eccentric force of a coil spring 13 with a support axis 8 as fulcrum. A fixed feeder 6 turns clockwise against an eccentric force of a coil spring 27 with a support axis 23 as fulcrum. In this manner, the members 11 and 24 are brought electrically into contact with each other to apply a power source, a test signal or like to an electric appliance on the pallet 3. After a test ends, the pallet 3 is moved even further to the right and the unit 5 and the unit 6 also further turn clockwise while the contact between the members 11 and 12 is released.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention is directed to the application of power supply voltage, test signals, etc. to electrical equipment on the transport belt in a production line between a transport belt and a pallet carrying electrical equipment. Concerning the electrical contactor end.

[Technical Background of the Invention] When manufacturing household electrical appliances, communication devices, or various electronic devices, a workpiece N is used to move these devices on a conveyor belt.
1. Equipment is mounted on m pallets, and work such as mounting and soldering of parts is carried out for each process. Some of these steps may require the application of power supply voltages or appropriate test signals to check the operation of the equipment.

In such a case, if the signals and the like are applied manually each time, the efficiency of one operation decreases, which is one of the reasons for hindering the mass production system.

[Objective of the Invention] The object of the present invention is to automatically and reliably contact a pallet moving on a conveyance line using a simple configuration, apply power, test signals, etc. to electrical equipment on the pallet, and make the pallet further It is an object of the present invention to provide a signal supply device whose contact is automatically released by movement.

[Configuration of the Invention] The signal supply device of the present invention is provided on a conveyance line,
a fixed supply device comprising a signal supply means to which a signal from a signal source is applied, and a first support means rotatably supporting the signal supply means in the direction of movement of the pallet; provided on the lower surface of the pallet; A sliding device comprising a sliding means for electrically contacting the signal supply means and applying a signal to an electric device, and a second supporting means for supporting the sliding means so as to be rotatable in the moving direction of the pallet. It has the following.

[Embodiment] Hereinafter, an embodiment of the present invention shown in the drawings will be described. A pallet 3 is placed on a conveyance line 1 so as to be movable by its running rollers 2.

On the pallet 3 is placed an electrical device 4 that is being assembled, such as a television receiver. A sliding device 5 is provided on the lower surface of the pallet 3, and a fixed feeding device 6 is provided at a predetermined process position on the conveyance line 1.

The sliding device 5 has a sliding means 9 rotatably attached to the lower end of a support member 7 erected on the lower surface of the pallet 3 by a support shaft 8 . The sliding means 9 has a female member 11 formed of a pair of conductive elastic plates on its lower surface;
1 and a protective plate 12 located on the outside of the protective plate 1 with a gap therebetween. The sliding means 9 is attached with one end of a coil spring 13 whose other end is fixed to the lower surface of the pallet 3.
The female member 11 is always elastically biased by the coil spring 13 so as to face diagonally downward in the direction of movement. This amount of deflection is regulated by a stopper 14 provided integrally with the support member 7. The female member 11 is electrically connected to the electric device 4 on the pallet 3 by a conductive wire 15.

The fixed supply device 6 includes a support member 22 that is inserted into and supported by a support post 21 provided on the conveyance line 1 so as to be movable up and down, and a signal support member 22 that is rotatably attached to one end of the support member 22 by a support shaft 23. The signal supply means 24 has a conductive male member 25 inserted therebetween so as to be in electrical contact with the female member 11 on its upper surface;
It has a pair of outer protection members 26 located outside the male member 25 at a distance and into which the protection plate 12 is inserted. The signal supply means 24 is attached with one end of a coil spring 27 whose other end is fixed to the support member 22, and this coil spring 27 causes the male member 25 to always face obliquely upward in a direction opposite to the direction of movement. The amount of this bias is regulated by a stopper 28 that is integrally provided on the support member 22. The male member 25 is connected to a signal source (not shown) or the like by a conductive wire 29. The support member 22 is a coil spring 3
1 is always elastically pressed upward.

As described above, the female member 11 of the sliding device 5 faces diagonally downward with respect to the moving direction of the pallet 3, and the male member 25 of the fixed feeding device 6 faces diagonally upward and in a direction opposite to the moving direction of the pallet. Since they are located respectively, Palette 3
As it moves on the conveyance line 1 from left to right in FIG. 1, the male member 25 is automatically inserted between the female members 11. As the pallet 3 moves further to the right, the sliding device 5 rotates clockwise about the support #18 against the biasing force of the coil spring 13. The fixed supply device 6 rotates clockwise around a support shaft 23 against the biasing force of a coil spring 27. The support member 22 that supports the male member 25 is always elastically pushed upward by a coil spring 31. Since the female member 11 and the male member 25 are pressed against each other, the contact between the female member 11 and the male member 25 is ensured.

By electrically contacting the female member 11 and the male member 25 in this manner, power, test signals, etc. are applied to the electrical equipment 4 on the pallet 3.

After this test is completed, by moving the pallet 3 further to the right, the sliding device 5 and the fixed feeding device 6
further rotates clockwise, and the contact between the female member 11 and the male member 25 is also released.

When the sliding device 5 is removed from the fixed feeding device 6, it is rotated counterclockwise by the coil springs 13 and 27, respectively.
Their rotation is restricted by hitting a stop 14, 28, respectively. Therefore, the sliding device 5 and the fixed feeding device 6 are again positioned as shown in FIG. 2, waiting for the arrival of the next pallet.

[Effects of the Invention] As described above, the signal supply device of the present invention automatically supplies power and test signals to electrical equipment on the pallet when the pallet reaches the power check process section or signal test process section on the conveyance line. It is not necessary to manually apply these signals each time as in the conventional case. Although the structure is simple, electrical contact can be made reliably.
