Description

The invention relates to the automation of assembly processes and can be used for the orientation of groups of parts such as contacts of plug connectors in the electronic and radio industry.

A device for orientation of parts is known. It contains a drive with sockets connected to a drive, a cutter and an orientator with through slots installed under it, at the entrance of which are orienting elements with profile slots equal to the number of ¹⁰ sockets of the drive and a feeder [1] .

However, in such a device it is difficult to change the orienting elements, which complicates the changeover of the device and makes it unprofitable to use it with frequent changes of ₁₅ batches of parts.

The aim of the invention is to improve the reliability of the device in operation and ensuring its versatility.

This is achieved by the fact that the orientator of the proposed device is equipped with a disk with radial through grooves installed with the possibility of rotation + a to align these grooves with the profile grooves of the orienting elements.

Orientation elements can be made in the form of interchangeable plates, the joints of which form the profile grooves. The orientator is equipped with a replaceable ring, which form with grooves orienting elements the shape of one of the ends of the oriented part.

FIG. 1 shows schematically the proposed device, a general view; in fig. 2 one of the sections, cut; in fig. 3 - section, the contact is pin down, cut; in fig. 4 - section, contact placed tail down; in fig. 5 and 6 - replaceable orienting elements.

The device for orientation of parts consists of a vibrating hopper 1, a tray 2 for feeding parts with ejectors 3 mounted on it and a sensor 4 controlling the passage of parts from the vibrating hopper into a disk drive 5 with slots for parts.

The disk drive rotates from the stepper drive 6.

Behind the disk drive is located

the shut-off device, made in the form of flaps 7,

located on axles 8, serving

a part of the dampers is connected by axes 9 with an overlay 757290

discs 10 and 11. The laid-on disc 10 is connected by a pulley 12 and a return spring 13 with an electromagnet 14 that controls the flaps 7. Under the cutter there is an orientator 15, on the case 16 of which a fixed disk 17 with through radial grooves 18 is installed. with radial through grooves 20.

The disk 19 has a protrusion that connects it with the pitch 21, operates from the electromagnet 22 and is installed in such a way that its through slots 20 do not coincide with the through grooves 18 of the fixed disk 17. To expand the range of orientable contacts without replacing the fixed disk 17, replaceable ones are located on it orienting elements 23, installed with the help of pins 24. Replaceable orienting elements 23 are made in the form of two plates, forming a groove profile with their joints.

The orientator is divided by partitions 25 and 26 into sections. The number of sections, holes and slots in the disks corresponds to the number of slots in the disk drive. A group feeder 27 is located behind the orientator. On the fixed disk 17 there is a ring 28, in the groove of which a protrusion of the disk 19 is mounted. The sections formed by the partitions 25 are open at the top and are closed by two conical guards forming the hollow body along the outer diameter and held by a spring ring The orientator can be equipped with a replaceable ring 30, which forms with grooves orienting elements according to the shape of one of the ends of the oriented part.

The device works as follows.

Parts from the vibrating hopper 1 through tray 2, accelerated by the ejector 3, enter the slots of the disk drive 5. Sensor 4 detects the passage of each part and sends a signal to the control unit 31, which counts the number of parts coming from the vibrating hopper 1, and sends a signal to the stepper drive 6 After receiving the signal, the drive 6 turns the disk drive 5 in such a way that its free slot is aligned with the axis of tray 2, and the part feeds into the slot. After the parts fill the specified number of slots in the disk drive, the signal from the control unit 31 stops working, the rotation of the disk drive also stops, the electromagnet 14 is triggered, which, using overlapping discs 10 and 11, simultaneously opens all the shutters 7 of the cutter. After actuation of the cutter parts at the same time fall into the grooves 20 of the disk 19. The disk 19 under the action of the spring 13 is in the extreme position in which the orienting elements 23 overlap the grooves 18 of the fixed disk 17.

After falling parts are located on the surface of the orienting elements 23, under the action of gravity slide on an inclined surface and occupy one of two positions in which the contact pin or entered with a thin diameter in the groove formed by the ring 30, the orienting element 23 and the disk 19, or the contact pin did not fit into the groove of the ring 30, since the dimensions of the grooves are smaller than the diameter of the shank. For this type of parts, the profile grooves can be made rectangular. Details with offset to one end of the groove and the same diameters of the contact and tail parts occupy the extreme position, resting on the inner end of the disk 19. In this case, the interchangeable ring 30 is not required.

When triggered electromagnet 22 through thrust 21 disk 19 moves to align the grooves 20 with the profile grooves of the orienting element 23. Details of the first type, located in the section, all fall out simultaneously with the same end, namely the tail part.

Details of the second type also fall out only at one end, i.e. in the place where the groove is combined with the protrusions of the key window. Out of the parts through the group feeder 27 is diluted by holes in the insulator. For a set of parts according to another scheme, the group feeder can be made removable.

Since the group feeder is installed behind the group orientator, a set of all simultaneously oriented parts of any type directly into the insulator is provided. The dampers open the entrance to the orientator by 0.3-0.5 sec, after which the vibrating bunker is closed and turned on, the contact recruitment process is repeated.

By replacing the ring 30 and the orienting elements 23, the device can be readjusted to various types of parts, such as rotation bodies, having any signs that allow to obtain an unambiguous loss of parts.

The vibrating bunker for feeding parts, the disk drive for parts with identical dimensions are constant, they work without changeover. For readjustment to another set or set of another type of contacts, the group feeder and the orienting elements can be replaced, the remaining units of the device remain constant.

This embodiment of the device for the orientation of parts allows you to simplify its readjustment to various types of parts, to expand the application, to execute it typical.
