摘要： PROBLEM TO BE SOLVED: To provide a plating device which is high in productivity, is simple in construction and is compact by making it possible to automate work for mounting, attaching and detaching lead frames and to execute a stage for removing the synthetic resin flashes adhered to these lead frames which is a pretreatment stage for a plating treatment stage with one device. SOLUTION: The lead frames 10 are inserted from above and are mounted by using a lead frame mounting mechanism to the inserting and holding parts 39 of lead frame holders 3 which have electrodes (cathodes) and hold plural sheets of the lead frames 10 mountablly, attachably and detachably in an erecting state in parallel. The plural lead frame holders 3 mounted with the lead frames 10 are circulated while these holders are successively moved and lifted intermittently in synchronization by moving and lifting mechanisms between plural treating vessels disposed in continuation and, thereafter, the lead frames 10 mounted in the inserting and holding parts of the lead frame holders 3 are pulled off from above by using the lead frame attaching and detaching mechanisms, by which the lead frames are detached.

摘要： PURPOSE:To provide the method for circulating plating treating liquid of a barrel for plating capable of efficiently forming uniform plating layers on the surfaces of objects to be plated and the device therefor. CONSTITUTION:A supporting shaft 3 for supporting the barrel for plating of the device for circulating the plating treating liquid of the barrel 1 for plating is bored with a through-hole 3a. This through-hole 3a is connected to a suction side 7a of a pump 7. The discharge side 7b of this pump 7 is connected to a plating treating liquid return pipe 9 disposed in a plating treating tank 10. The plating treating liquid in the barrel 1 for plating is sucked from a suction pipe 6 connected to the through-hole 3a and the sucked plating treating liquid is introduced from the plating treating liquid return pipe 9 into the plating treating tank 10.

摘要： PURPOSE:To avoid electrical trouble and to form a uniform plating layer on a material by providing plural feed terminals on the inner periphery of the outer diameter of a cylindrical barrel and connecting the terminal to a sliding contact at the center of rotation through a protected conductor. CONSTITUTION:Plural feed terminals 4 of a hard conductive material are provided at regular intervals on the inner periphery of the outer diameter of an octagonal-sectioned cylindrical barrel 3 of PVC, etc. The barrel 3 is rotated in a plating soln., a power is supplied to the terminal 4, hence a material and the terminal 4 are uniformly energized, and a plating layer is electrodeposited. The terminal 4 is brought into contact with a conductor 5 on the terminal side through a screw. Meanwhile, the conductor 5 is protected by a conductor cover 16 of PVC, etc., on the barrel side, kept away from the plating soln. and connected to the contact 6. Consequently, the trouble due to the cutting of a cable, defective contact, etc., is not caused as in the case of the conventional barrel plating device.

摘要： PURPOSE:To forcibly move the works in a cylindrical barrel in a barrel shaft direction without disposing specific means in this barrel and without increasing its size by specifically arranging and fixing plural body plates having an isosceles triangle shape or trapezoidal shape. CONSTITUTION:The plural body plates 31b to 31d... having the isosceles triangle shape or trapezoidal shape (the body plates 31a, 31h at both ends are formed to a right-angled triangle shape for the purpose of forming the apertures for inlet and outlet of the works) are arranged in such a manner that the bases of the isosceles triangle shapes exist alternately between the adjacent body plates. The body parts 31 of the cylindrical barrels 3 are assembled by fixing the bases of the isosceles triangle shapes to side plates 32 in such a manner that the hypotenuses of the isosceles triangle shapes constitute ridges. Plating treatment is executed by rotationally driving such cylindrical barrel 3, by which the purposes are achieved and the uniform plating layers are efficiently formed.

摘要： PURPOSE:To rapidly and perfectly house and discharge objects to be plated by dividing cylindrical parts of a barrel for plating in parallel with a supporting shaft and relatively shifting the positions of side face plates of the divided cylindrical parts to form an aperture. CONSTITUTION:The cylindrical part of the barrel 1 for plating is equally divided to the two semi-polygonal columnar cylindrical parts 6a, 6b parallel with the supporting shaft 3. Both side parts of the cylindrical plates constituting the cylindrical parts 6a, 6b are provided with the side face plates 7a, 7b. The axial length of the cylindrical part 6a is set longer than the length in the cylindrical part 6b and the barrel is so assembled that the side face plate 7a exists on the outer side of the side face plate 7b. The cylindrical parts 6a, 6b are provided with detaining members 9 in the proper positions of the cylindrical plates constituting these parts. The positions of the side face plates 7a, 7b are relatively shifted around the opening/closing supporting shaft 8 in the state of directing the positions provided with the detaining members 9 to the upper side. As a result, the opening is formed between the cylindrical plates constituting the cylindrical parts 6a, 6b. The objects to be plated are housed into the barrel 1 from this opening.

摘要： PURPOSE:To excellently maintain the circulation of plating soln. and the flow of a plating current by laminating plural barrel sheets at intervals to constitute the barrel and shifting the positions of through holes bored in the laminated barrel sheets from one another. CONSTITUTION:Two barrel sheets 2 and 3 are laminated at a space to constitute a rotary plating barrel 1. The positions of many through holes 2a and 3a bored in the sheets 2 and 3 to the plating soln. are shifted from one another between the laminated sheets 2 and 3. A body to be plated passing through the through hole 2a of the inner barrel sheet 2 is held by the outer barrel sheet 3, and the body is not dropped outside the barrel 1. Consequently, the numerical aperture can be increased as compared with the conventional plating barrel.
