Description

  The present invention relates to a chemical processing apparatus that performs chemical processing while conveying an extremely thin and flexible long sheet-shaped workpiece such as a flexible substrate at a constant speed, and in particular, chemical processing can be performed without generating workpiece tarmi. The present invention relates to an improvement of a chemical processing apparatus that can be used.

  In recent years, electronic devices have increasingly used flexible substrates that are extremely thin and flexible. Corresponding to such a flexible substrate, Patent Document 1 discloses that a long sheet-like workpiece (substrate material) wound on a reel is continuously arranged with its width direction set in the vertical direction (that is, with the workpiece surface set in the vertical direction). A plating tank is placed between the workpiece supply device that supplies the workpiece and the workpiece winding device that continuously winds the workpiece on the reel with the width direction set to the vertical direction, and the workpiece (substrate material) is long. An apparatus for performing a plating process in a sheet form has been proposed.

However, since the plating apparatus described in Patent Document 1 has a structure in which only the upper end of a long sheet-like workpiece (substrate material) is clamped and transported, the workpiece is wide and extremely thick. If it is thin, there is a problem that tarmi occurs in the workpiece during the process of conveying the workpiece or the process of plating, making it difficult to stably convey the workpiece in the vertical direction. Was.

It has upper and lower end conveyance clamp groups that clamp the upper and lower ends of the workpiece when the chemical treatment tank is loaded into the chemical treatment tank, and the upper and lower end conveyance clamp groups are fixed to a pair of independently driven endless belts at equal intervals. Each time the workpiece is clamped and conveyed with its width direction set to the vertical direction, the upper and lower transfer clamps are opened sequentially when the workpiece is unloaded in the chemical treatment tank, and only the workpiece that has been chemically processed is moved in the vertical direction. In this manner, a workpiece transfer device is provided which is wound on a reel of the workpiece winding device.

Next, the invention according to claim 2
In the chemical processing apparatus according to the invention of claim 1,
The transport speed of the upper and lower end transport clamps is controlled by a pair of upper and lower independent servo motors that independently drive a pair of endless belts and a sensor that detects the amount of movement of the pair of endless belts, while the upper and lower end transport clamps are synchronized. It is characterized by conveying work,
The invention according to claim 3
In the chemical processing apparatus according to the invention of claim 1 or 2,
The upper end conveyance clamp group is fixed to one endless belt arranged on the upper side, and the lower end conveyance clamp group is attached to the other endless belt arranged on the lower side so as to be movable in the vertical direction. The workpiece is transported while applying a force in the vertical direction by the weight of the transport clamp group,
The invention according to claim 4
In the chemical processing apparatus according to the invention of claim 1, 2, or 3,

A chemical treatment tank 4 for performing chemical treatment such as plating, and an untreated workpiece 1 is carried into the chemical treatment tank 4 with its width direction set to the vertical direction, and the processed work 1 is set to the vertical direction with respect to the width direction. The main part is comprised by the workpiece conveyance apparatus 20 carried out in this way.

  That is, a workpiece supply device 2 for supplying a long sheet-like workpiece 1 wound on a reel, a workpiece winding device 3 for winding the workpiece 1 on a reel, and the workpiece supply device 2 and the workpiece winding device 3. A chemical treatment tank 4 is provided between them, and the chemical treatment tank 4 is composed of a plurality of tanks according to necessary steps. Further, since the workpiece 1 is continuously conveyed from the workpiece supply device 2 to the workpiece winding device 3 with its width direction set to the vertical direction, the upper end and the lower end of the workpiece 1 are clamped at the time of loading into the chemical treatment tank 4, respectively. A workpiece transfer device 20 is provided for transferring the workpiece.

  The workpiece transfer device 20 is arranged to face a plurality of upper end transfer clamps 5 for clamping the upper end of the workpiece 1 and a plurality of lower end transfer clamps 6 for clamping the lower end of the workpiece 1 and an upper pulley 101 covered with rubber through a predetermined distance. An upper endless belt 81 wound between the upper pulley 121 and attached to the upper end conveying clamp 5 group, and a lower pulley 122 disposed opposite to the lower pulley 102 covered with rubber through a predetermined distance. A lower endless belt 82 wound around and attached to the lower end transport clamp 6 group, and provided on the upper pulley 101 and the lower pulley 102, respectively, and independently drives the upper endless belt 81 and the lower endless belt 82. A pair of upper and lower independent servo motors 91, 92 and the endless belts 81, 82 A photoelectric sensor 11 for detecting the movement amount of each endless belt by detecting marks (not shown) provided in the vicinity and provided on each endless belt, and the vicinity of the outer peripheral surfaces of the upper pulley 101 and the lower pulley 102 Of the upper end transport clamp 5 group and the lower end transport clamp 6 group at the timing when the rollers 21 and 22 (see FIGS. 3 and 4) attached to the upper end transport clamp 5 group and the lower end transport clamp 6 group contact each other. An arc-shaped contact plate 7 is provided in which each clamp is opened.

  When the workpiece 1 is loaded into the chemical treatment tank 4, the rollers 21 and 22 attached to the upper end transport clamp 5 group and the lower end transport clamp 6 group are pressed against the abutting plate 7 to release each clamp, and The upper end and lower end of the workpiece 1 supplied from the workpiece supply device 2 with the width direction set to the vertical direction from the workpiece supply device 2 at the timing when the contacts of the rollers 21 and 22 with the contact plate 7 are finished and the clamps are closed. The 5 group and the lower end transport clamp 6 group are smoothly clamped, and the upper end transport clamp 5 group and the lower end transport clamp 6 group are attached to a pair of endless belts 81 and 82 that are independently driven at regular intervals, respectively. Then, the workpiece 1 is carried into the chemical treatment tank 4 with its width direction set up and down while being clamped.

  When the chemically treated workpiece 1 is carried out in the chemical treatment tank 4, the rollers 21 and 22 attached to the upper end conveyance clamp 5 group and the lower end conveyance clamp 6 group are sequentially pressed against the abutting plate 7, and each clamp is moved. Only the workpiece 1 that has been opened and chemically treated is wound on the reel of the workpiece winding device 3 with its width direction set to the vertical direction.
