Description

The invention relates to the production of radio components and can be used for marking resistors and other cylindrical radio components with axial leads.

The purpose of the invention is to improve the operational capabilities of the device by providing automatic flushing of the labeling rollers and simplifying the changeover of the device when the label is changed. I.

FIG. 1 depicts the proposed

device general view; 2, the same top view; in fig. 3 is a section A-A in FIG.

The device contains a carriage 1, which can move along the guide 2 and the lead screw 3, which causes rotation from the stepping days ™ of the bar 4, mounted on the base 5. On the carriage 1, there is a stepper motor 6, on the shaft of which is a cliché 7, representing a resilient flap disk with marking marks, two electromagnets 8 and 9 and a reddish roller 10, on which paint comes from tank 12 through hollow sleeve I1. On base 5 there is a drive mechanism containing a stepper motor 13 and a shaft 14 equipped with minutes keyed (not shown) on the shaft 14 coaxially arranged two markings 16 and the roller 15 (roller 15 is shown in the labeling position, and the roller 16 - to the washing position). The rotation from the stepper motor 3 can be transmitted to the lead screw J 7 through the electromagnetic clutch 18 and the gear pair 19.

The marking rollers 15 and 16 are mounted in a movable carriage 20 mounted for reciprocating movement along the spindle screw 17 and the guide 21. Symmetrically with respect to the marking position, two washing rollers 24 and 25 are located on the guides, the role of which is performed by the axes of electromagnets 22 and 23 immersed in the baths 26 and 27 with the washing liquid, the washing rollers 24 and 25, when triggered by the electromagnets 22 and 23, have the opportunity to interact with the marking rollers 15 and 36. nsporter 28 and the drum 29, which is manufactured marking products 30.

The device works as follows.

On command from a software device (not shown), the stepper motor 6 rotates the cliche 7 through a certain angle. The selected cliche 7 stands in front of the paint roller 10, comes into contact with it through the striker of the electromagnet 8 and is painted. Then the stepping motor 6 turns the cliches 7, the sign stands in front of the marking roller 15, and the print is transferred to the marking roller 15 by striking the electromagnet 9. Then the carriage .1 moves to niar markings along the guide 2 and the lead screw 3, which is driven by the rotation of the stepping motor 4. The next cliche sign is selected and colored, and when the carriage 1 moves n step Labeling, a fingerprint pad 7 transferred to the marks paid-roller 15. Then, the stepper motor 4 moves the carriage 1 to the home position corresponding to the top line. At the same time, the stepper motor 13 rotates the shaft 14 from the seat shaft on the common key with the rollers 15 and 16 at a given angle corresponding to the distance between the marking lines. Sequential transfer of the selected characters from the cliché to the marking roller 15i takes place.

This cycle continues until all selected prints are transferred to the marking roller 15. Thus, all the information that is to be printed on the product is automatically applied to the marking roller. After that, the electromagnet 23 triggers and moves the washing roller 25 under the marking roller 16 (it is assumed that the marking roller 16 was previously at the marking position and left fingerprints on it). Then, the stepping motor 13 is turned on and drives the shaft 14 with the marking rollers 15 and 16 located on it, which sit on a common key, which strictly fixes them relative to the key. Thus, the marking rollers 15, and 16 make a complete revolution around their axis. In this case, from the marking roller 15, the prints applied as indicated are transferred to the product 30, which is on the drum 29. At the same time, from the marking roller 16, the washing roller 25, which is immersed In the washing liquid, all the previously printed prints are washed off. This is ensured by the washing roller 25 being located under the roller 16 so that during the complete rotation of the shaft 14 with the rollers 15 and 16, the marking roller 16 and the washing roller 25 come into contact, and due to the friction forces the roller 16 rotates the washing roller 25 at an angle which is determined by the diameters of the rollers 16 and 25.

After stopping the stepper motor 13, the electromagnet 23 is turned off and returns the washing roller 25 to the initial position, i.e. moves it out from under roller 16 (removes from contact). After that, the product 30 enters the conveyor 28. When marking the products of one batch of Beci, the cycle is repeated, except that the electromagnet 23 is not turned on, since all the prints are washed away from the marking roller. Before marking the products of the other lot, the electromagnetic clutch 18 is turned on, and the rotation from the stepper motor 13 is transmitted through the gear pair 19 to the spindle. 17, while the movable carriage 20, the locking marker rollers 15 and 16, move along the guide 21. At the same time, the rollers -15 and 16, rotating, move by the carriage 20 along the shaft 14, and the roller 15 moves from the marking position to the washing position the electromagnet 22, the washing roller 24 and the bath 26, and the roller 16 to the marking position, after which the products 30 of the new batch are marked, which are fed to the drum 29 by the conveyor 28.
