According to the positioning device present invention, the base plate repatriation unit 10, a vertical rail 1
It moves in the longitudinal direction of the electrolytic cell group along the line 04 and stops at a predetermined electrolytic cell position with high accuracy. Accordingly, the carriage 11 of the motherboard lifting device 10 is provided with a positioning device.

In the present embodiment, as will be better understood with reference to FIGS. 6 to 8, the traveling distance of the carriage 10, which constitutes a detection unit of the positioning device, is provided on the carriage 10. A traveling distance detection device 40 for performing measurement is provided.

The traveling distance detecting device 40 has a measuring wheel 42 rotatably attached to one end of a support plate 41. The support plate 41 swings around the fulcrum 43 and
The other end is connected to a tension spring 44. The other end of the tension spring 44 is fixed to the vertical frame 13 of the trolley, and thus presses the measuring wheel 42 against the vertical rail 104. The measurement wheel 42 is, for example, lining its surface with urethane rubber so that the measurement wheel 42 engages with the upper surface of the vertical rail 104 and rotates together with the movement of the carriage without slipping.

5 are connected via a coupling 46 and the wheels 4
From the rotation of 2, the traveling distance of the cart 11, that is, the motherboard lifting device 10 can be measured.

In order to maintain the accuracy of moving and stopping the mother plate lifting device 10 at a high accuracy of ± several mm, the amount of movement is detected by using a rotary encoder 45 capable of detecting with a minimum accuracy of 0.1 mm.

However, since the detecting unit is the traveling distance detecting device 40 constituted by the mechanical contact as described above, a cumulative error occurs in the electrolytic cell far from the origin.

Therefore, according to the present invention, means is provided for canceling (presetting) the accumulated error caused by the detection unit. In this embodiment, a sensor dog (preset dog) is used as the accumulated error canceling means.
This preset dog was provided corresponding to each electrolytic cell, and the stopping accuracy was maintained with high accuracy.

... If the actual value measured by the rotary encoder 45 is, for example, 4006 mm when the motherboard lifting device 10 has passed the position of, for example, 4000 mm, for example, 4006 mm. , This value is converted to 4000 mm.

Therefore, assuming that the error of +6 mm is canceled and the target stop position is 4100 mm, a short moving amount of another 100 mm may be measured by the rotary encoder 45, the error amount is reduced, and the stopping accuracy is improved. Can be maintained.

Further, as shown in FIG. 10, the preset dog 61 is connected to both sides of each electrolytic cell 100, that is, the parallel vertical rail 1
In the case where the proximity switch 63 is disposed corresponding to the carriage 11 of the motherboard lifting device 10 and the proximity switch 63 is disposed, it is also possible to monitor whether the motherboard lifting device 10 is traveling in a skew state. .
