Input and output device with frame
In order to manufacture an input and output device industrial use as cost-effectively as possible, while also fulfilling the demanding requirements in an industrial environment, it is provided that the frame of the input and output device is assembled from a plurality of individual frame sections which are connected to one another at the corners in order to form the frame and which are firmly bonded at the adjoining connecting surfaces in order to form a fully sealed external front face of the frame and a fully sealed external peripheral surface of the frame.
1. An input and output device for industrial use comprising:
a frame that includes a plurality of individual frame sections having connecting surfaces, wherein adjoining connecting surfaces of the plurality of individual frame sections firmly bonded to one another at corners of the frame using a glue joint,
wherein an adhesive gap in a range of 0.05 mm to 0.2 mm is formed between two adjoining frame sections and is filled with adhesive,
wherein the adhesive, as a joining agent, forms a bonding layer which is fully sealed in an area of an external front face and an external peripheral surface of the frame in order to form a fully sealed external front face of the frame and a fully sealed external peripheral surface of the frame, and
wherein the assembled frame includes a continuous central recess configured for an input/output unit to be set in.
2. The input and output device according to claim 1 , wherein at least two adjoining frame sections are mitered or dovetailed in order to form the connecting surfaces.
3. The input and output device according to claim 1 , wherein at least one of the external front face and the external peripheral surface is finished after joining with at least one of an even external front face and external peripheral surface by removing protruding joining agent.
4. The input and output device according to claim 1 , further comprising a cover sheet that covers at least the bonding layer and is glued over at least one of the external front face and the external peripheral surface.
5. The input and output device according to claim 1 , wherein, at least in the bonding area, at least one of the external front face and the external peripheral surface is painted or coated.
6. A method for the production of a frame which is sealed around a periphery for an input and output device for industrial use, the method comprising:
assembling the frame from a plurality of individual frame sections that are connected to one another at corners of the frame,
wherein the frame sections have connecting surfaces and are firmly bonded to one another at adjoining connecting surfaces using a glued joint, where an adhesive gap in a range of 0.05 mm to 0.2 mm is formed between two adjoining frame sections and is filled and cured with an adhesive as a joining agent, thereby forming a bonding layer which is fully sealed in an area of an external front face and an external peripheral surface of the frame in order to form a fully sealed external front face of the frame and a fully sealed external peripheral surface of the frame.
7. The method according to claim 6 , further comprising at least partially finishing a joint in order to form a flawless surface.
8. The method according to claim 7 , further comprising removing joining agent escaping from the adhesive gap before curing.
9. A method for production of an input and output device for industrial use with a frame that is sealed around a periphery and that is manufactured according to claim 6 , the method comprising:
inserting an input/output unit into a continuous central recess in the frame.
