Definitions

  • Fluidic control device and method for its manufacture
  • the invention relates to a fluidic control device and a method for its production according to the preambles of independent claims 1 and 3.
  • a control device for a piston-cylinder unit can be seen, for example, from EP 0 316 500 A1.
  • an intermediate plate mechanically connected to the cylinder is used, which has through openings which go from one of its surfaces to the other in order to connect the outlet opening of the valve to the spaces of the cylinder. With such an intermediate plate, different switching options can be implemented.
  • a pressure medium connection between a valve block and a consumer having at least one double-acting pressure medium motor is also known from DE 29 33 704 A1.
  • a sealing plate is used which has openings which act as control channels running in the plane of the plate, which in different working positions Connect different connection openings of a valve block housing and a consumer housing.
  • the object of the invention is therefore to provide a fluidic control device, for example a pneumatic or pneumatically operated valve. til and to develop a method for their manufacture such that the above-mentioned problems are eliminated and a wide variety of control channel profiles can be implemented with little installation effort and consequently low costs. In particular, an optimal sealing of the control channels should also be realized.
  • the basic idea of the invention is to limit and seal the control channels by means of weld seams produced by means of laser welding.
  • the weld seam provides an optimal hermetic seal of the control channels without the need for mesh seals.
  • a wide variety of control and supply channels can be realized by laser welding.
  • switching volumes that result in the coordination of different switching times can also be changed or varied easily and simply.
  • the arrangement of the weld seams does not require any additional machining effort.
  • Another decisive advantage is that the manufacturing process can be automated.
  • the cover element preferably consists of a plastic which allows transmission of the laser beam.
  • the laser beam is advantageously focused so that its focus is in the area of the channel edges.
  • the laser beam is moved along the channel edges, preferably in an automated manner.
  • control ⁇ / supply channels or the fluid channels have fluid barriers that can be removed in a targeted manner. Melting away, exchangeable inserts in the plastic tool, which is used to manufacture the base body / cover element, etc. In the case of melting away, the laser beam is preferably used here, with which the weld seams for sealing the control / supply channels are also realized.

  • FIG. 2 shows a plan view of a base body of the fluidic control device shown in FIG. 1;
  • 3a shows an embodiment of a cover element of one of the
  • 3b shows a further exemplary embodiment of a cover element of a fluidic control device making use of the invention
  • Fig. 4 is a sectional view taken along IV-IV of the base body shown in Fig. 2 and
  • Fig. 5 is a sectional view taken along the line V-V of the base body shown in Fig. 2.
  • a fluidic control device in the form of a pneumatic valve shown in FIGS. 1 a, b, has a base body 100 on which a cover element 200 is fastened.
  • Control / supply channels 210, 212 which are connected to control A / supply channels 110, 112, are provided in the cover element 200 or in the base body 100.
  • a cylinder space 120 is arranged in the base body, for example, in which a piston or slide 130 or a membrane or a combination thereof is movably guided.
  • the fluidic control device can be preceded by a so-called pilot valve or a pilot control 300, which can optionally be connected to the control / supply channels 210, 212 via fluid channels 114, 115, 116. As shown in FIG. 1b, this can be done, for example, by boring, Breaking or breaking through fluid barriers in the form of barriers, which are arranged between the channel 114 and the channels 115, 116, happen. It should be emphasized that the control channels 210, 212 can be arranged not only in the cover element 200, but also in the surface of the base body 100 facing the cover element 200 or also partially in the surface of the base body 100 and in the cover element 200. The control channels 210 , 212 are delimited by weld seams 700 which are arranged in the region of the channel edges.
  • the cover elements 500, 600 are made of a plastic that is transparent to the laser beam, so that a laser beam, such as is used for laser welding, passes through the cover element 500, 600 to the webs 450.
  • This laser beam is focused in the area of the webs 450 and melts the webs 450.
  • the heating can take place on the one hand by focusing, on the other hand by absorption on the base body 400.
  • the base body 400 is in this case in fact opaque to the laser beam, so that the web is melted by the impact of the laser beam and the corresponding reflection. Due to the pressure applied to the cover element 500, 600 at the same time, the heat is transferred to the cover element 500, 600 and leads there to a partial warming.
  • the base body 400 and the cover element 500, 600 connect.
  • the resulting weld seam seals the channels 510, 520 or 610, 620, 630 arranged in the cover elements 500, 600 and at the same time fastens the cover element 500, 600 on the base body 400.
  • a base body 400 which is transparent to the laser beam and in this case a cover element 500, 600 which is impermeable to the laser beam can also be provided.
  • a web 455 can be arranged in the base body in the area of the control channel 620, 630 to be formed later.
  • the cover element 600 has a fluid barrier 645 in the form of a wall. This wall can be provided with predetermined breaking points and can be removed by puncturing, breaking away and the like, so that channels 620, 630 become a single continuous channel. If the fluid barrier 645 is not broken away, a weld seam is also formed in the area of the web 455, so that the channels 620, 630 are separated from one another, which results in another control possibility for the control device. This removal of fluid barriers can be understood as "programming".
  • control devices for example 3/2-way valves or 5/3-way valves Valves can be realized with the same basic bodies and cover elements, which leads to a considerable reduction in the number of parts and tools in the manufacture of the basic bodies and cover elements and thus to a cost-effective implementation of such control devices.

Abstract

L'invention concerne un dispositif de commande fluidique comportant au moins un actionneur fluidique, telles que des pistons, membranes, tiroirs, corps de base présentant des associations de ces derniers ou similaires, ainsi qu'au moins un élément couvercle. Des canaux de commande/d'alimentation, qui sont en communication fluidique avec des canaux de fluide situés dans le corps de base, sont situés dans le corps de base et/ou dans l'élément couvercle. Selon l'invention, les canaux de commande/d'alimentation sont délimités entre le corps de base et le ou les éléments couvercle par l'intermédiaire de cordons de soudure produits par soudage laser.
