The specific embodiment is as follows:

The above-described handling device is described below with examples in specific applications:

The handling device 70 has a clamping assembly 170 for clamping the FPC substrate. The carrier device 70 carries the FPC substrate at a speed of 0.5m/min to 3.0m/min, preferably 1.0 m/min. For example, when the FPC substrate is transported at a speed of 1.0m/min, it takes 3 minutes to reach the inlet portion 61 of the electrolytic plating tank 60 from the outlet portion 42 of the electroless plating tank 40. If the time is about 3 minutes, the electroless plating layer C will not oxidize even if the FPC substrate passes through water.

Fig. 2 is a schematic structural view of the clamping assembly 170. The clamp assembly 170 includes a T-shaped main body 171 and left and right clamps 172, and an elastic member such as a spring 174 is provided between the main body 171 and upper portions of the left and right clamps 172, and the left and right clamps 172 can be opened and closed freely.

The roller 175 mounted on the upper outer side of the clamp 172 is freely rotatable, and the contact portion 173 for holding the FPC substrate mounted on the tip of the clamp 172 is freely attachable or detachable, or is freely slidable. The clamping assembly 170 is typically made of energizable stainless steel, but the body 171 may be made of reinforced plastic. When the main body 171 made of reinforced plastic is used, the main body 171 and the contact portion 173 are connected by a copper plate, a conductor such as a coated copper wire, or the like, and can be energized. The clamp 172 is bent in a U-shape from a stainless steel plate. The roller 175 may be made of stainless steel, but is preferably made of plastic resin such as engineering plastic for weight saving. The contact portion 173 is covered with a resin such as rubber or soft plastic (except for the contact point with the FPC substrate).

As described above, the contact portion 173 is attachable to and detachable from, or freely slidable from, the clip assembly 170, and thus can be easily used as a clip assembly corresponding to the size and shape of the FPC substrate, such as the width and length thereof.

Fig. 3 is a schematic view of the conveying device 70. The conveying device 70 moves the clamp assembly 170 for holding the FPC substrate, and is composed of a plurality of connection members 272 (see fig. 1) provided between left and right driven sprockets (not shown) and a drive sprocket 71 provided above the inlet side of the pretreatment unit 30 and above the outlet side of the electrolytic bath 60, and the left and right conveying chains 271 and 271 wound therearound.

The attachment member 272 has mounted thereon the clamping assembly 170. In addition, the connection member 272 is made of metal, and is brought into contact with the cathode rod 69 provided in the electrolytic plating tank 60 when passing over the electrolytic plating tank 60, and the current flowing between the anode 65 and the FPC substrate is grounded to the outside through the clamp assembly 170 and the cathode rod 69.

The distance between the left and right conveyance chains 271 may be larger than the width of the electrolytic plating tank 60. After the carrying chain 271 is provided at this position, even if foreign matter such as dust, metal powder, grease, etc., falls onto the carrying chain 271, the plating solution of the electrolytic plating tank 60 is not mixed.

Fig. 5 is a schematic view of the opening and closing mechanism 275 of the clamp assembly 170 in the conveying device 70.

An opening and closing mechanism 275 for opening and closing the clamp assembly 170 in the electrolytic plating tank 60 is described herein. The electroless plating vessel 40, the pretreatment unit 30, and the washing tank of the washing unit 50 may have the same structure.

The opening and closing mechanism 275 is composed of "left and right guide rails 276 provided at substantially the same height as the rollers 175 of the clamp unit 170 and along the conveying direction". The guide rail 276 is formed with a curved portion 276A at a predetermined position of the electrolytic plating tank 60 to reduce the left-right spacing. When the roller 175 of the movable clamp assembly 170 abuts the curved portion 276A, the clamp 172 is opened and the FPC substrate is released, exceeding the force of the spring 174. Also, after the clamping assembly 170 passes through the bending portion 276A, the clamp is closed again due to the elastic force of the spring 174, clamping the FPC substrate. Such an opening and closing mechanism 275 can arbitrarily set the opening and closing position of the clamp assembly 170. However, in the above embodiment, the opening/closing mechanism 275 bends the guide rail 276 to form the bent portion 276A, but as shown in fig. 5, the opening/closing mechanism 275 may be composed of a linear guide rail 277 and a bending member 278. Such a bending member 278 may be added with an open and closed position later.

It will be clear to those skilled in the art that, for convenience and brevity of description, reference may be made to the corresponding process in the foregoing method embodiment for the specific working process of the apparatus described above, which is not described herein again. In the several embodiments provided by the present application, it should be understood that the disclosed apparatus may be implemented in other ways.

The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
