Abstract:
In order to remove treatment liquid (21) from a planar material to be treated (10), which is transported in an assembly for the electrolytic or wet-chemical treatment of the material to be treated (10), or to promote the exchange of material on the surface of the material to be treated (10), a roll with a roll surface (4, 14) is provided. The roll surface (4, 14) is arranged relative to a transport path of the material to be treated (10) so that a gap (8, 18) remains between the roll surface (4, 14) and a useful region of the material to be treated (10) opposing the roll surface (4, 14), which extends over the useful region. The roll is driven rotatably so that at the gap (8, 18) a relative speed is produced between the roll surface (4, 14) and the material to be treated (10).
Abstract:
The present invention relates to treatment units for the wet-chemical or electrolytic treatment of flat workpieces (1), such as metal foils, printed circuit foils or printed circuit boards, in which the workpieces (1) are transported on a conveying path by means of conveying members (6, 6′, 6″, 7). The treatment unit comprises carrier elements (4) with recesses (21), said carrier elements (4) being oriented to be parallel to the conveying path, and at least one module system for carrying the conveying members (6, 6′, 6″, 7) that consist of insertion elements (14, 26), preferably arranged in pairs, the at least one module system being configured such that it registers with and is preferably slidable into the recesses (21) of the carrier elements (4). The treatment unit is preferably utilized in horizontal conveyorized lines.
Abstract:
The present invention relates to a vertical system for the plating treatment of a work piece (W), the said system including at least two treatment modules (100) and at least one transport device for conveying at least one work piece (W) to a treatment module (100) and for transferring the work piece (W) to retaining devices (130) in the treatment module (100). The retaining devices (130) for the work piece (W) are provided in the treatment modules (100). The transport device includes at least one gripping device (10) retaining the work piece (W) each with at least one fastening device (20, 30). Each fastening device (20, 30) includes first clamping devices (25, 35) that are each associated with one side of the work piece (W) and second clamping devices (26). At least one first clamping device (25, 35) associated with a first side of the work piece (W) is designed and disposed such that the position of the first side of the work piece (W) can be defined by the first clamping device (25, 35). At least one second clamping device (26) associated with a second side of the work piece (W) is designed and disposed such that a clamping force can be exerted onto the work piece (W) by the said clamping device. Both the first clamping device (25, 35) and the second clamping device (26) are moveable. According to the invention, the gripping device (10) is actuated as follows: a) moving the first clamping device (25, 35) such that the first clamping device (25, 35) takes over a contact position and thereby the position of the first side of the work piece (W) is defined, and b) moving the second clamping device (26) such that the second clamping device (26) takes over a clamping position and the work piece (W) is thereby clamped together with the at least one first clamping device (25, 35). In doing so the first clamping device (25, 35) takes over the contact position before the second clamping device (26) takes the clamping position.
Abstract:
An apparatus for the electrolytic treatment of the product L using a treatment agent is used to make the treatment of a plate-shaped product more uniform. This apparatus includes: devices for retaining 40, 42 the product L in the apparatus, one or a plurality of flow devices 10, which each include at least one nozzle 15 and are disposed situated opposite the product L, one or a plurality of counter electrodes 30, which are inert relative to the treatment agent and are disposed parallel to at least one treatment surface, means for generating a relative movement 44 between the product L, on the side, and the flow devices 10 and/or the counter electrodes 30, on the other side, in at least one direction parallel to a treatment surface. The product L can be immersed into the treatment agent during the treatment.

Abstract:
In order to remove treatment liquid (21) from a planar material to be treated (10), which is transported in an assembly for wet-chemical treatment of the material to be treated (10), a retaining surface (4, 14) is provided for holding back the treatment liquid (21). The retaining surface (4, 14) is arranged relative to a transport path of the material to be treated (10) so that a gap (8, 18) remains between the retaining surface (4, 14) and a surface of the material to be treated (10) opposing the retaining surface (4, 14), when the material to be treated (10) is moved past the retaining surface (4, 14). The retaining surface (4, 14) may, for example, be provided as an offset portion of a peripheral surface of a roll (2, 3).
Abstract:
A nozzle arrangement is described which may in particular be used as a flow nozzle in galvanization systems with horizontal throughput of printed-circuit boards. The nozzle arrangement comprises a longitudinal housing (2) with at least one fluid feed opening to feed a treatment fluid for treating a work piece, for example a printed-circuit board, and preferably a plurality of slotted fluid delivery openings (8) for releasing the treatment fluid. In the housing (2) a fluid channel (5) is formed for feeding the treatment fluid from the fluid feed opening to the fluid delivery openings (8). In order to achieve the most even possible flow speed of the treatment fluid at the fluid delivery openings (8), (a) the throughput of the fluid channel (5) for the treatment fluid reduces continuously from the fluid feed opening in the longitudinal direction of the housing (2) and/or (b) before the delivery of the fluid from the fluid delivery openings (8) a storage chamber is provided.
