Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a presser for holding or pinching an object to be plated while pressing the object to be plated in a carrier for transferring the object to be plated in a plating line.

[0002]

[Prior art]

 The requirements for the object to be plated on the plating line are, firstly, that the object to be plated must be held securely and that it can be easily attached and detached. Secondly, after immersion of the object to be plated in the treatment liquid, the liquid adhering in the form of vapor, splash, or the like is easily cut off, and residual droplets are less likely to stay on the surface of the lever. The reason why good drainage is required is that after plating, the portion of the entire object to be plated that is held by the retainer is not scratched and does not form a suitable film. Although it is cut and discarded as scrap, in order to reduce the amount of scrap as much as possible, the lever is passed through the surface of the processing tank to rub against it, and as a result, adhesion of the processing liquid to the lever is inevitable. . When the conventional presser foot is evaluated based on the conditions described above, the presser foot that has been conventionally arranged on the carrier has a mechanical force that causes the lever to swing when attaching or detaching the object to be plated. It was equipped with a suitable pressurizing unit, and was satisfactory in terms of ease of attachment and detachment.

[0003]

[Problems to be solved by the device]

 However, in the conventional presser, the objective part that presses the object to be plated is welded to the arm including the fulcrum of swing, and the plate surface and the thick surface of the lever are lacking in smoothness as a whole. In addition, residual droplets of the treatment liquid are likely to stay in the corners of the welded portion, and as a result, mixing of different treatment liquids becomes a problem when passing through a plurality of treatment layers. In addition, a certain level of strength is required when transporting various objects to be plated. In order to give a certain level of strength to the welded part, it depends on the thickness of the lever. It is necessary to take at least about 6 cm, and as a result, for example, when holding an object to be plated that has unevenness on the sandwiching surface with a carrier in which a plurality of pressers are juxtaposed side by side in a row, It becomes difficult to set the width of the objective part narrow and hold a large number of pressers per unit width in order to hold the object finely in a state of imitating the holding surface of the object. However, due to the poor holding efficiency of the objective part against the object to be plated, there are often cases where the object to be plated falls, and this sometimes causes an accident. It was difficult to do.

In view of the above situation, the present invention is capable of securely holding an object to be plated and easily attaching and detaching the object, and further, immersing the object to be plated in the treatment liquid, and then depositing the liquid in the form of steam or splashes. The purpose is to provide a presser foot with good cutting.

[0005]

[Means for Solving the Problems]

 A presser foot according to the present invention made to solve the above problems is fixed to a carrier provided with an electrode that moves along a carrier rail so as to face the electrode and to press an object to be plated onto the electrode. A holding tool for holding the arm which has a vertically long transverse section and an objective section having a horizontally long horizontal section, which are integrally formed on a base body fixed to the carrier by twisting one plate. It is characterized in that a hook-shaped lever constituted by the above is supported so as to be swingable back and forth about a horizontal axis and biased so as to bring the objective portion into contact with the electrode.

[0006]

[Embodiment of device]

 Embodiments of a presser foot according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a side view of an example of the presser foot. In this pressing tool, an arm portion 4 and an objective portion 5 are integrally formed on a carrier body 2 provided with an electrode 1 that moves along a carrier rail, on a base body 3 that is fixed to face the electrode 1. The lever 6 is supported by a horizontal shaft 7 so as to be swingable forward and backward and biased so as to bring the objective portion 5 into contact with the electrode 1.

The base body 3 is formed, for example, by bending a stainless steel plate into a bilaterally symmetrical bifurcated shape, and forming a flat portion on the bent base portion to be joined to the surface of the electrode 1 of the carrier 2 in a plane. A bolt hole 8 for fixing to the carrier 2 and a positioning claw 9 are provided in the portion, and the tips of the portions 10 and 10 which are divided into left and right forks with the flat portion as a boundary are bearing portions 11 and 11, respectively. A shaft hole for inserting a horizontal shaft 7 for supporting the levers 6, 6 so as to swing back and forth and stoppers 12, 12 for limiting the swinging of the levers 6, 6 face each other in the bearing portions 11, 11. The hooking portions 14, 14 for hooking one ends of the springs 13, 13 are provided opposite to each other near the flat portion of the bifurcated portions 10, 10.

The lever 6 is a pressurizing member that mechanically applies a force to swing the lever 6 when attaching / detaching the object to be plated and the object 5 to be contacted with the arm 4 which is bent in a hook shape. The part 15 is integrally formed by using one strip of steel plate, and the arm part 4 and the pressurizing part 15 have the points of increasing the number of levers 6 arranged per unit width, improving the drainage, and In consideration of the convenience of supporting the shaft, the cross section is continuous in a vertically long state. On the other hand, the objective section 5 has a cross section that is easy to hook and has a large contact area. It becomes horizontally long, and in the form near the boundary, a gentle and smooth twist of 90 degrees is applied at the boundary between the arm 4 and the objective 5. A hook hole 16 for hooking the other end of the spring 13 is provided at the tip of the arm portion 4, and the tip of the objective portion 5 is shaped like a saw blade to increase the pressure applied to the contact point. A shaft hole through which the swing shaft 7 is inserted is provided near the boundary between the arm portion 4 and the pressing portion 15.

When viewed from the side, the arm portion 4 and the pressurizing portion 15 are bent like a dogleg, and the arm portion 4 itself is bent like a hook in the opposite direction. When viewed from the side, the pressing portion 15, the arm portion 4, and the objective portion 5 have a continuous S-shape. That is, the hook-like shape may have a hook-like portion that bulges against the side where the object to be plated is clamped so that it can be easily held and held. It is suitable to be smooth. Further, when the lever 6 shown here is viewed from the front, the pressing portion and the arm portion are bent and formed so as to be shifted in the same direction with respect to the shaft supporting portion. This is because, when supporting the pair of levers 6 and 6 on one substrate 3, the objective parts 5 of the levers 6 and 6 do not come into contact with each other or the pressurizing part 15 does not approach. Is. It is desirable that these bent portions should be as gentle and smooth as possible like the twisted portions.

Two levers 6 and 6 are interposed between both bearings 11 and 11 of the base body 3 with a disc-shaped separating member 17 interposed therebetween, and a rocking shaft 7 is inserted into and supported by them. Springs 13, 13 are hooked between the hooking holes 16, 16 provided in the arm portions 4, 4 of 6, 6 and the hooking portions 14, 14 provided in the base body 3, respectively. Due to the force of the springs 13 and 13, the levers 6 and 6 exert a restoring force so as to always contact the stoppers 12 and 12 provided on the base body 3. In addition, insulating resin tubes 19 and 19 are attached to the hook portions 18 and 18 of the springs 13 and 13 on the base body 3 side, whereby the objective portions 5 and 5 of the levers 6 and 6 are attached. Electrolytic corrosion due to contact with dissimilar metals between the electrode and the electrode 1 is prevented.

Usually, the carrier 2 is provided with a predetermined width so that a plurality of holding tools can be arranged side by side so as to hold a wide object to be plated. A copper electrode 1 having a hook shape in a vertical cross section as shown in FIG. 1 is fixed to its full width, and the copper electrode 1 itself also serves as a member for catching or holding an object to be plated. The base 3 of the presser is fixed to the carrier 2 via the electrode 1, and the positioning claws 9 are fitted in the recesses on the surface of the electrode 1 so that the levers 6 of each presser are arranged in an orderly manner. Becomes By pressing the pressurizing unit 15 with a hydraulic jack or the like, the holding of the object to be plated can be released, and conversely, when the force of the hydraulic jack is no longer applied, the action of the spring 13 causes The lever 6 returns, and when there is no object to be plated, the end surface of the objective portion 5 of the lever 6 comes into contact with the end surface of the electrode 1. In addition, in this presser, the ribs are directed toward the inside of both bearings 11 and 11 so as to impart an appropriate swinging resistance to restrain the rattling of the lever 6 and stabilize the swinging trajectory. 20 and 20 are projected.

The presser foot according to the present invention is configured as described above, and the arm portion 4 having a longitudinal cross section and the objective portion 5 having a transverse cross section are integrally formed by twisting a strip steel plate by 90 degrees. By molding, the restrictions on the width of the objective section 5 and the wall thickness of the lever 6 are removed, and it becomes possible to manufacture the lever 6 having the objective section 5 having a narrow lateral width, and the plate gently and smoothly twisted. The residual drops of the processing liquid came to flow favorably along the surface and the thick surface. As described above, in the presser foot according to the present invention, since the flow of the residual droplets on the surface of the lever 6 is important, the curve is gentle and smooth toward the tip of the lever 6, and the residual droplets are likely to stay. That is, it is desirable that the shape is such that there is no acute angle portion. Further, the shape of the objective portion 5 may be appropriately changed according to the object to be plated so that it can be easily held.

[0013]

[Effect of device]

 As described above, when the presser foot according to the present invention is used, the retention of the treatment liquid, which has been a problem with the conventional presser foot, is reduced, and the mixing of different treatment liquids when passing through multiple treatment layers is reduced. Coloring process, especially color unevenness of white and similar colors is greatly reduced, which contributes to the improvement of product quality, and it is also necessary to maintain a predetermined strength and finely hold it in a state of imitating the sandwiching surface of the object to be plated. By setting the width of the objective part to be narrow and arranging a large number of pressers per unit width, it is possible to arrange multiple pressers in a horizontal row in close proximity to each other to form a concavo-convex on the clamping surface. When holding a certain object to be plated, the posture of the object to be plated in the holding state is stabilized, and the efficiency of holding the object part against the object to be plated is also improved. To prevent the occurrence of So that the increase.
