Title: Device for removing electronic component and jig for the removal
Inventor: ARAYA TATSUYA
IPC: B23K1/018
Filed: 1988-04-15
Abstract: PURPOSE:To remove components from the surface of a slanted substrate without deforming pins of component and without damaging the component substrate, by providing an electronic component removing means consisting of an electronic component holding means, and an electronic component extract/driving means, and a copying, positioning, and heating means. CONSTITUTION:After raising the temperature of a heating means 60 and holding a printed substrate 72 in such a way that it comes closely into contact with its lower surface, solder in the through hole 3 is melted by heating. Then, a positioning means 20 moves horizontally and allows an electronic component removing means 54 to perform positioning at an upper side of electronic component 70 to be removed. After that, when an elevating cylinder 34 makes the electronic component removing means lower and the lower part of a copying plate 43 of a copying means 40 together with the removing means abut on the surface of the printed board 72 simultaneously, a copying base 41 is slant and a hole 42 located at the upper side of its base is released from a taper part 37 and comes to a state in which the copying base becomes unrestricted. Then, if its elevating cylinder 34 makes the copying plate 43 lower, the electronic component removing means 54 is tilted by following an inclination of the printed board 72. And when an electronic component extract/driving means 53 holds the electronic parts, the electronic component 70 move vertically with respect to the surface of the printed substrate 72 and a pin 71 is extracted from the inside of the through hole 73.

The output result of the counter is inputted as distrubance data as it is. In addition, until the value of the counter becomes the maximum value or the minimum value, a WAIT signal at an 'H' level is generated, and an adjusting operation is interrupted during their period.  When the adjusting operation is not performed according to an adjusting-operation control signal from a system controller, the disturbance data is set at '0' by the AND gate of an output end, Then, a defocus state is changed when the disturbance signal is changed from a positive polarity to a negative polarity or from the negative polarity to the positive polarity, a slew rate is added, and the disturbance signal is defocused slowly.
