Description

The invention relates to the process equipment for the production of electronic equipment and relates to devices with software control for the automatic laying of wires in permanent storage devices of transformer type, on the boards and during installation of the panels.

The purpose of the invention is to improve the quality of wrap and increase productivity in the work due to the introduction of a mechanism for correcting the error of the product.

FIG. I presents the kinematic diagram of the device; in fig. 2 - the relative position of the probe of the mechanism for correcting the error of the product and the paver in the initial position; in fig. 3 - movement of the probe relative to the wire layer by a distance determined by the position of the stop; in fig. 4 - installation of the needle of the wirelayer at a given distance from the surface of the product before winding the wire onto the contact; in fig. 5 - move the probe to its original position before winding the wire on the contact; in fig. 6 - cheat the wire on the contact.

The device for laying the wires includes a housing I, a drive 2 moving the wire paver perpendicular to the plane of laying with an electric motor 3 installed in the guides on the body I of the slider 4, on which the wire paver 5 and the rack 6 are fixed, and the product error correction mechanism containing the slide 7 on which fixed probe 8, kinematically connected with the drive 2, the stop 9 and the toothed rack Yu. On the output shafts II and 12 of the drive 2, there is a friction clutch 13 connecting the shaft II with the gear 14, and an electromagnetic friction clutch 15, connecting shaft 12 with a gear 16. The gears 16 and 14 are in engagement with the racks 6 and 10, arranged on slides 4 and 7, respectively. Through the hole in the paver 5, the wire 17 is missed. Article 18 contains contacts 19, on which wire 17 should be provided during installation, and (or) other structural elements that require laying the wire at different levels. To install the product 18 in a predetermined position serves as the mechanism 20 to move the product in the plane of installation associated with the device 21 controls.

The actuator 2 includes a gearbox 22 and a displacement count sensor, for example, a slotted disk 23, a photodetector 24 and an illuminator 26. The clutch 13 includes a disk 26 mounted on the shaft 1 1, a disk 27 mounted on the shaft 1 1 rotatably, and a spring 28. The clutch 15 includes a disk 29 mounted on the shaft 12, a disk 30 mounted on the shaft 12 for rotation, a disk 31 with a stop fixed on the disk 30, springs 32 and 33, an electromagnet 34

with an anchor 35, on which is fixed a bracket 36,

and building 37.

The device works as follows.

On commands from the device 21 controls the mechanism 20 movement in accordance with a given program, the product 18 moves in the plane of installation. Moving the slide 4 with the wire-laying machine 5 perpendicular to the plane of installation from the electric motor 3 through the drive 2, shaft 12, clutch 15, gear 16 and toothed rail 6. Drive 2 when the engine 3 is turned on, rotates the shafts 11 and 12 in the same direction and with the same speed, therefore, the slider 7 with the probe 8 through the clutch 13, the gear 14 and the toothed rack 10 move in the same direction and at the same speed with the wirelayer 5. Correction of the position of the wirelayer 5, taking into account the errors of the product 18, is performed as follows. The movement mechanism 20 aligns the desired point of the product in the stacking plane with the axis of the conductor 5, for example, at the next contact 19. Then the electromagnet 34 is turned on, the anchor 35 of which by the bracket 36 covering the disk 31 pulls the disk 30 away from the gear wheel 16. This breaks the gear linkage 16, and consequently, the slider 4, on which the wire-laying device 5 with the drive 2 is attached, as the gear 16 is pressed by the spring 33 to the end of the housing 37 and is braked. After that, the electric motor 3 is turned on and through the gearbox 22, the shaft 11 with the disk 26 and the gear 14 moves the slider 7 with the probe 8 down (Fig. 2). Slider 4 is held by gear 16 and remains stationary until those holes until stop 9 begins to move it along with slide 7. By the time slider 4 begins to move, the end of the probe 8 extends over the end of the wire-laying machine 5 by the amount determined by the position of the stop 9 (Fig. 3) . The amount of movement of the probe 8 by the control device is predeterminedly greater than the distance from the end face of the probe 8 to the surface of the product 18, therefore the probe 8 always rests against the product, and with further rotation of the motor 3, the disk 26 slips relative to the gear 14. After the end of the probe rests product 18, the end of the wire-laying machine 5 stops at an exact distance from the surface of the product 18. This position of the wire-laying machine 5 is accepted by the control unit as zero, and all movements to the next correction are set from this zero (FIG. 4). After the conductor 5 is stopped, the probe 8 is retracted by the engine, opening the working part of the conductor by an amount that excludes changing the zero position of the wire of the depositor 5 (Fig. 5). Then turns off the electromagnet 34 of the coupling 15 and continues with the further laying of the wire 17 on the product 18

according to a given program (Fig. 6). When laying and correction, the movements of the wire paver 5 are counted according to the number of pulses transmitted to the control device 21 from the photodetector 24, which occur when the grooves of the disk 23 pass between

the photoreceiver 24 and the illuminator 25. The probe 8 is moved together with the wirelayer 5. To avoid damage to the wire 17, a hollow is made at the end of the probe 8, through which the wire 17 freely enters when the probe 8 is pressed to the product.
