Description

one

The invention relates to radio engineering, in particular, to devices designed to remove from the axial terminals of the radio components of the oxide film and contaminants that prevent the production of high quality solder joints.

Devices are known for stripping axial leads of radio components containing a transport mechanism and wiper blades with reciprocating movement | one .

A disadvantage of the known devices is the cyclical nature of the work, namely, during the supply and removal of radio components from the treatment area, the stripping knives of the device are idling.

The purpose of the invention is to increase productivity.

This is achieved by the fact that in a device for stripping axial leads of radio components, containing a transport mechanism made, for example, in the form of a drum and sweep knives, the latter are made in the form of discs aligned coaxially with the drum and fixed at an angle to the axis of its rotation.

FIG. 1 shows a device for stripping axial leads of radio components, a cross section; in fig. 2 is a section along A-A in FIG. 1. The described device contains a transport mechanism made in the form of a drum 1 rotating on pins 2 inserted into bearings 3. Two rings 4 are attached to the ends of drum 1, forming an annular groove for housing the radio components 5.

Cleanup knives, made in the form of discs 6, are located coaxially with the drum 1 and fixed at an angle to the axis

rotation on the hubs of the drive shafts 7. A clamp 9 with an elastic shock absorber 10 is mounted on the bracket 8. The clamp 9 is fixed on two columns 11,

having threaded ends and fitted with adjusting nuts 12. Between the bracket 8 and the clamp 9 on the columns 11 there are springs 13,

To the right and left of the clamp 9, arc strips 14 are attached to the croutine 8, concentrically to the stripping knives. They form the supporting surface for the leads 15 of the radio components 5 during their stripping. The slats 14 have a resistive work surface, which is based on friction and better fit of conclusions 15,

The rings 4, attached to the drum 1, have grooves on the outer circumference corresponding to the diameter of the leads 15. The grooves are milled with a pitch ensuring the free placement of radio components 5. The drive gear 1Y is located at the linkage with the gear wheel cut on the drum 1.

The puller 17 serves to remove the processed radio components, and the charging chute 18 to feed them to the drum 1.

The device works as follows.

From tray 18, radio parts 5 are fed in a continuous stream into drum 1. Conclusions 15 radio components fall into the slots on the rings 4. The drum transports radio components to the zone where they interact with clamp 9 rotates relative to its own axis.

Simultaneously with the drum 1, but with a considerably greater speed, the sweep knives, cutting them with the help of which they make one double xoh along the axis of the leads 15, rotate the cutting knife simultaneously in one revolution

so that their cutting edges converge and are dispersed relative to the housings {rear parts 5 at the same time. Each disc 6 is mounted on your drive hub 7 so that its cutting edge is located on the side opposite to drum 1.

After the stripping operation, the radio components 5 are removed by the puller 17 from the drum 1.
