DD264623A1 - DEVICE FOR AUTOMATIC LAYING OF THIN PAINTED WALLS IN THE GRID WITH HIGH ACCURACY - Google Patents

Abstract

The invention relates to a device with programmable memory for automatic lattice-laying laying duenen Lackdraehten with high accuracy in particular for the production of measuring plates for digitizers on a x-; y-coordinate table. On the coordinate table there are two CCD line scan cameras which can be pivoted by 90 horizontally, which control deviations in the position of the wires and the wires for cracks, creases and knot formations and shut down the device in the case of quality defects.

Description

Explanation of the essence of the invention

The invention therefore has the task of creating a device of the type mentioned.

According to the invention this is achieved in that the device adjusts not only the wire tension and thus the Drahtvorspe tion, but also electronically controls and the wire grid with two Legende different cross-section advantageously laid the enamelled wire gently, the density of the grid is variable.

A weitps feature of the invention is that on the x-y slide two 90 ° horizontally pivoting CCD line scan cameras are provided which control the dimensional deviations of the position of the wires and the wires for cracks, creases and knots and shut down the device in case of quality.

embodiment

The invention will be explained in more detail below using an exemplary embodiment. In the accompanying drawing show:

Fig. 5 Structure of the frame

Fig. 1 shows the complete frame 1, which receives the automatically placed wire mesh 8. The frame 5 is provided with the x-y slide 5, on which the wire laying head 4 mounted pivotably by 90 ° with the two CCD line scan cameras is arranged. Further provided on the frame 1 functional modules are explained in more detail in Fig. 5.

Claims (4)

1. An apparatus for automatically laying thin enameled wires in the grid with high accuracy in particular for the production of measuring plates for digitizers odf an xy-coordinate table, characterized in that the frame (1) receives the automatically placed wire mesh (8) and above the frame (1 ) of the xy carriage (5) is provided, on which the 90 ° pivotally mounted wire laying head (4) arranged with two CCD line scan cameras (7) and a small Leefinger (15) are provided by the large Leefinger (16) is guided and on all four sides of the frame (1) spring strips (17), Spannbackonleisten (18), the clamping jaws (19) lead, and support strips (20), the laying strips (21) record, are provided and outside of the frame (1 ) the pneumatic units clamping jaws (22) and wire stop means (23) are arranged. 2. Device according to claim 1, characterized in that the supply reel (3) feeds the wire (6) to the frame (1) which drives the direct current motor (2) controlled by the actuator (10), the wire (6) via the intended ijmlenkrolle (12) with the buffer path (14), which is defined by the spring (11) runs. 3. Apparatus according to claim 1 and 2, characterized in that the wire (6) is guided by the small Leefinger 15 and pulled over the edge of the large Legefingers (16). For this 4 pages drawings Field of application of the invention The invention relates to a device with programmable memory for the automatic grid-like laying of thin enamel wires with high accuracy, in particular for the production of measuring plates for Diyitalisiergeräte on an x-y-coordinate table. Characteristics of the known prior art There are known solutions by the form of cable automatically in dor horizontal plane for a given program on punched tape strips are loosely placed around laying pins. These solutions allow only the processing of insulated wires, because no gentle handling of the material is ensured. By DD 213776 a method and an apparatus for the production of MeßplaUen for digitizers have become known, with which a grid-shaped wire mesh is produced, however, requires a high manual labor. Object of the invention The aim of the invention is an automatically operating device for laying thin enamel wires ι in the grid with high accuracy in avoiding the known disadvantages and omission monotonor activity for the production of high-resolution digitizers or other grid-like structures of metallic materials with similarly required parameters. Fig.2 illustrates that the supply reel 3 feeds the wire 6 dom frame 1, which drives a DC motor 2, which controls the actuator 10 because of the different swirling trajectory 9, advantageously the pressure transducer 6 being used for lifting the traction forces 9, e.g. B. at start accelerations, on the intended guide roller 12 and the Pufferlungs 13 with the buffer section 14, which is defined by the spring 11 runs. Fig. 3 and 4 cleats small Legefinger 15 in its movement, which is guided by the large Leefinger 16. Fig.5 illustrates that on all four sides of the frame 1 spring strips 17, clamping jaw 18, the jaws 19 lead, and support strips 20, the Legoleisten record 21, are provided. Furthermore, it can be seen that outside the frame 1, the pneumatic units "clamping jaws" 22 and "wire stopping device" 23 are arranged. FIG. 3 shows the wire (3) coming from the buffer station 13, which is guided through the small assembly finger 15 and pulled over the edge of the large release finger 16. 4 illustrates that the wire 6 comes in its further movement between the exact position of the wire C determining Legelfiisten 21. After the large Legefinger 16 has run over the mats 21, the small Legefinger 15 is brought into the lower end position. In d'eser phase of the 'xleine Legefinger 15 comes to position 24 and there performs the eccentric movement 25 to the jaw 19 through. The wire 6 gets then by the support strips 20 the gunaue altitude. The pneumatic unit "clamping jaws" 22 presses the clamping jaws 19 in the laying phase up to stop of the support bar 20. The spring bars 17 pulls the clamping jaws 19 back to relief and the wire 6 is stretched in a defined manner This happens when the wire mesh is laid. 23 becomes mutually effective, (i.e., when the wire-laying head 4 moves from left to right, the pneumatic unit 23 becomes left-acting, but only when the wire-laying head 4 has moved out of the frame 1, until then the pneumatic unit remains "Drahtstoppainrichtung" 23. The pneumatic Einhiait "wire stopper" 23 pushes the wire 6 in operation on the support strips 20. When the wire laying head 4 in the frame 1, the pneumatics "wire stopper" 23 is retracted without function and horizontally retracted.
