Abstract:
Objects, (4) especially vehicle bodies (4), are guided through a painting installation comprising at least one bath (2) in a continuous translation movement, by means of a transport device (5). Immersion devices carry the objects using a carrier structure (61) which is connected to the transport device (5) in such a way that it can be pivoted by a pivoting arm (50, 51). A first drive device (54, 55, 56, 57) causes a pivoting movement of the pivoting arm (50, 51) about a first axis. A second drive device (78, 79, 80, 81) is used to pivot the carrier structure (61) about the second axis, in relation to the pivoting arm (50, 51). One such immersion device enables very different kinematics of the immersing and emerging movement to be carried out.
Abstract:
Apparatus and method for treating a surface of a substrate for electrolytic or electroless plating of metals in integrated circuit manufacturing. In one embodiment the method includes forming a barrier layer on a substrate. A metal-seed layer is then formed on the barrier layer. The method continues by performing in situ surface treatment of the metal-seed layer to form a passivation layer on the metal-seed layer. In another embodiment of a method of this invention, a substrate is provided into an electroplating tool chamber. The substrate has a barrier layer formed thereon, a metal seed layer formed on the barrier layer and a passivation layer formed over the metal seed layer. The method continues by annealing the substrate in forming gas to reduce the passivation layer. A conductive material is deposited on the substrate using an electrolytic plating or electroless plating process.
Abstract:
A resin application station has processing units for heating dynamo-electric machine components. In one or more of the processing units batches of components are placed in fixtures on vertically rotating support plates. The vertically rotating support plates are mounted in cabinets. Heated air is circulated in the cabinets to control the ambient temperature. The components travel through regions of the controlled temperature ambient as the support plates rotate and are heated to process temperatures. Intermittent rotation of a support plate in a unit allows loading and unloading of an individual component from the unit while the support plate is stationary. The support plate rotations in all the units are synchronized to increase the station throughput
Abstract:
In a pressure infiltrating apparatus 20 according to the invention, an upper end of an inlet side orifice 23 in the drawing is formed to take a tapered convex shape and a lower end of an insertion hole of an intermediate orifice 25 in the drawing is formed to take a concave shape having a diameter gradually increased corresponding to the convex shape of the inlet side orifice 23. Consequently, a space A between the inlet side orifice 23 and the intermediate orifice 25 is set to be small without damaging the fluidity of a molten metal 11 between the inlet side orifice 23 and the intermediate orifice 25 in a bath container 22.
Abstract:
In equipment for powder-coating, workpieces such as escalator steps are subjected to a current treatment in an anodizing unit. A conveying means advancing carriers for the workpieces is lowered over a tank so that the workpieces in transit are immersed in and continue transit within a bath and after a specific dwell time are lifted back out of the bath at the end of the tank. Arranged in the tank region is a current feed, such as a bus bar, which extends parallel to the travel path of the conveying means. Each carrier is provided with a current take-off which connects the carrier with the current feed. The current connection is produced on lowering the carrier into the bath and interrupted on raising the carrier from the bath.
Abstract:
Disclosed herein is a coating system for pre-coating a vehicle chassis, comprising a coating station and a curing oven, the coating station being upstream from said curing oven along a travel path, the coating station to deliver a layer of coating material thereon, the chassis having a number of sites, each of which is known to be source for accumulating excess coating to cause unwanted drips thereof during curing, further comprising a plurality of nozzles, each being in a nozzle group of one or more, where each group is arranged to deliver a flow of air sufficient to remove the excess coating.
Abstract:
A dip-spin coating apparatus and method is described. A disk is partially immersed into a coating liquid and rotated while the disk is maintained in a substantially vertical plane. Once the disk is coated, the disk is removed from the coating liquid where excess material is spun off at a higher rotational speed while the disk is maintained in the vertical plane.
Abstract:
Disclosed herein is a feed belt for strip-shaped elements. In case of a conventional feed belt configured so that its belt body and fingers are integrally formed, the feed belt has to be wholly replaced even if a part of the fingers is damaged or deformed in use, resulting in uneconomical problems. Further, the fingers must be simultaneously pressed toward each other into horizontal pressing directions for loading/unloading of the strip-shaped element, resulting in a complexity in the structure of associated peripheral devices. Even in case of another conventional feed belt configured so that its fingers are separably coupled to its belt body, the fingers have to be pressed upward in operation, resulting in a complexity of associated devices. This separable type conventional feed belt further causes various problems including the unintentional separation of the fingers, malfunction due to sliding or pushing of the strip-shaped element gripped by the fingers, an increase in manufacturing costs due to the complex structure of the fingers, and the like. The feed belt of the present invention results in a considerable improvement in the structure of fingers and a belt body, thereby eliminating the unintentional separation of the fingers during operation as well as sliding or pushing of the strip-shaped elements gripped by the fingers. Further, according to the present invention, it is possible to considerably reduce manufacturing costs by forming each finger as a single integral member, and to enable the fingers to be pressed in a horizontal direction, thereby simplifying the structure of peripheral loading/unloading devices. As a result, the feed belt of the present invention can be widely applied to a transfer field where loading, feeding and unloading of strip-shaped elements are automatically performed.

A machine for impregnating a die cast metal part with liquid impregnant comprises an impregnation chamber having liquid impregnant in a lower portion, an opening for ingress and egress of the parts being defined in a side wall of the chamber above the liquid impregnant, a door for sealing the opening, a part holder in the chamber and an elevator for positioning parts above the liquid impregnant during evacuation of the chamber and then immersing the parts in the liquid impregnant during subsequent pressurization of the chamber.
Abstract:
A pickup head for engaging an integrated circuit from a first side. The pickup head can dip solder bumps disposed on an opposing second side of the integrated circuit into a layer of flux on a flat surface in a uniform manner. An arm attaches the pickup head to a mobility unit, and a retainer selectively retains the first side of the integrated circuit against the pickup head. A pivot is disposed between the arm and the retainer, and enables the retainer to pivot and the integrated circuit to freely align with the flat surface in such a manner that as many of the solder bumps as possible are in contact with the flat surface, regardless of variations in heights of the solder bumps. The solder bumps are thereby more uniformly coated with flux.
