SU978402A1 - Cassette for radio components - Google Patents

Description

The invention relates to special process equipment and can be used in automatic lines for the assembly and processing of printed circuit boards.

A known cassette for radio components, comprising a housing, in the walls of which slots for axial leads of radio elements are made, cutters accommodated in the housing and connected to the drives, and a supporting element 13.

However, the known device is unreliable in operation.

The purpose of the invention is to increase the reliability of work.

The goal is achieved by the fact that in the cassette for radio elements, comfortably, mainly with axial leads, comprising a housing, in the walls of which slots for axial leads of radio elements are made, the cutters - located in the housing and connected to the drives, and the supporting element - have one of the cutters a projection whose height is equal to the height of the part, and is installed with the possibility of interaction with the supporting element.

The supports element is made in the form of a permanent magnet, and the body

magnetic cassettes.

The supporting element is provided with orienting elements placed by J wall slots.

FIG. 1 shows a cassette, a longitudinal section in FIG. 2 is a section A-A in FIG. i; in fig. 3 shows an embodiment of a supporting element.

Claims (3)

The cassette contains side 1 and end 2 walls made of magnetic material, two cutters 3 and 4 placed one above the other, interacting with drives 5 and 6, and the bottom cutter 4 is equipped with a profiled protrusion made in the form of a roller 7, the diameter of which is equal to the height parts 8. A supporting element 9, made in the form of a permanent magnet with an orienting cushion 10, is installed in the cassette case. Parts 8 are fed into the cassette from the device for leveling the axial leads. The cassette is fixed with the help of lugs 12 and 13. The ejector rod of the supporting element 9 is inserted through the opening B in the bottom of the cassette. The supporting element 9 can be equipped with orienting elements 14 if the cassette does not have end walls 2. The cassette operates as follows. The Ida device for aligning the axial leads produces parts 8, which are mounted in the cassette so that their axial leads are located in the axes of the slots G of the walls 1. The supporting element 9 is in its extreme top position and held on the cassette of the cassette due to the forces of friction arising when interacting its magnetic field with walls 1 or 2, both cutters 3 and 4 are put forward on the rifle. The first part B is lowered onto the orienting cushion 10 of the supporting element 9. With the help of the drive, the lower pusher 4 is moved smoothly along the control system signal, which by means of the profiling lug with the rotating roller 7 pushes the part 8 and the supporting element 9 downwards. The actuator 6 retracts the slam-shutter 4 by the action of its own weight, moves the next part 8, the slam-shutter 4 vyov moves to the cassette and again pushes the next part 8 and the element 9 down. The cycle is repeated until the cartridge is full. The size of the magnet is chosen in such a way that the friction force holding it due to the magnetic field is enough to hold the full column of parts 8. When operating in the mode. the dispensing cassette is reversed and re-secured with nposinHH 12 and 13. In this case, each cutter 3 and 4 is moved. First, the cutter 3 is pulled out and part 8, located between cut-off devices 3 and 4, is pulled out, then the cutter 3 is inserted into the cassette , - the cutter 4 is pulled out and reintroduced into the cassette, with the next part 8 taking the place between the cutters. The distance between the cutters is equal (or somewhat greater) to the height (diameter) of the part 8. The dispensing cycle is repeated until the cassette is completely empty. In the case of using a supporting element with orienting elements 14, the filling and stopping cassette cycles are carried out in a similar way. Claim 1. A cassette for radio elements, mainly with axial leads, comprising a housing, in the walls of which slots for axial leads of radio elements are made, cutters placed in the housing and connected to the drives, and a supporting element, characterized in that, in order to increase reliability work, one of the cutters is provided with a protrusion whose height is equal to the height of the radio element and is installed with the possibility of interaction with the supporting element. 2. The cassette pop. 1, distinguishes a, so that the supporting element is made in the form of a permanent magnet, and the body of the cassette is made of magnetic material. 3. Cassette on PP. 1, 2, characterized in that the supporting element is provided with orienting elements located in the slots of the walls. .Sources of information taken into account during the examination 1.
