Description

The invention relates to process technology (ore for the production of radio equipment and can be used in the installation of printed circuit boards.

A device for mounting transistors to a printed circuit board, containing a mechanism for forming radio components with clamping jaws, a mechanism for capturing radio components, is made in the form of a punch with slots for signals of radio components and an ejector 1 j |

The disadvantages of this device are limited technological capabilities | since it ensures the installation of only such radio elements, the findings of which during molding can be bent over the dimensions of the radio element body, moreover, such molding of radio elements does not ensure high density of radio elements on the printed circuit board.

The closest to the proposed invention is a device for installing radio elements on a printed board with a radio element clamping mechanism, made in the form of a collet with clamping jaws, which have grooves for the elements of the radioelements, an ejector and a clamping jaw drive mechanism} A disadvantage of the known device is There is a low density of installation of radio elements on a printed circuit board, taj as a significant free zone between radio elements is required to divert the jaws of the mechanism for capturing radio elements ...

The purpose of the invention is to increase the density of the installation of radioelemites.

This goal is achieved by the fact that the device for the installation of radio elements on. a printed circuit board containing a clamping mechanism for radio elements with clamping jaws in which grooves for the outputs of radioelements are made, an ejector and a mechanism for driving the clamping jaws, the clamping mechanism of radio elements is completed in the form of spring-mounted disks that are continently mounted on the axis of the spring-loaded discs. on the end surface of the discs, and the mechanism for driving the clamping jaws is made in the form of a pusher mounted to interact with cylindrical protrusions.

Capture Capacitors; in fig. 6 - installation of capacitors.

The device contains a mechanism of 1 clamping of radio elements, designed to capture and mold radio elements, made in

3 coils 4 with clamping jaws 5, made in the form of cylindrical protrusions located on the face surface of the disks 4, coaxially mounted on the axis 2, spring-loaded coil spring. the gripper is provided with a coil spring 3, and a clamping jaw drive mechanism, designed in the form of a pusher 9, established with the possibility of reciprocating movement and reacting with cylindrical projections S in the casing 10, .naruzhnoy surface; which is made pazovps cam. The pusher 9 is connected to a running thread with a bevel gear 11, inside which is placed a b1. 12, having the ability to move progressively into the groove of gear II and rotate with it. The finger 13 of the ejector 12 slides along the groove cam of the housing 10. The revolving-rotational movement of the gear 11 receives from the horses 1 hectare gear

gears with bevel gears 14 and 15 and a cylindrical gear rack and pinion with gear wheel 16 and gear rack 17. Case 10 has the ability to swing, from 90 to axis 18. Spring force 19 through rail 20 and the gear sector is transmitted to body 10 The locking mechanism consists of a fixed guide 21 and a disk 22. with a flat, rigidly connected to the housing 10. The dog 23, controlled by the rail 17, is designed to hold the axis 18 in the lower position at the time of installation of the radio element 7 and open the jaws 5 of the mechanism 1 of the clip.

To center the housing 10 in the position of the radio element, a fixed centering ring 24 is designed. For installing various radio elements in the device, various gripping mechanisms can be installed, for example, the mechanism 25 for transistors and the mechanism for gripping 26

conditors that differ in shape, grooves for leads, are in sponges 5. The device operates as follows. The radioelectric elements 7 are fed into the clamping mechanism 1 and placed between the jaws 5. The rake 17 moves downward under the action of the pylevmo cylinder (not proven) and transmits the rotation through the gears 16, 15 and 14 to the gear 11, and the bevel gear collar 14 slides freely on the axis 18 The tine gear 11 rotates using a thread to move the pusher 9 to the left, which acts on the jaws 5 of the clamping mechanism 1 and brings them closer, making the centering of the discharge element 7 and the yoke of the preformed molding (if necessary). The housing 10 is held in a horizontal position by a spring 19, acting through the rail 20 into the third sector of the housing 10. After reaching a certain forming force, the spring 19 is matched and the bevel gear 14 rolls back over the wheel 15, slipping along with the housing and axis 18 to a vertical position. The spring 19 force of the spring when the body 10 rotates and the rake 20 rises, therefore, the jaw 5 of the radioelement clamping mechanism increases and finally the molding ends when the body 10 rotates. When the radio element is compressed and molded, the device works as a simple gear rack with a rail 17 and a gear wheel 16, as well as a bevel gear with wheels 15, 14, and gear I. After the gear 11 stops (compression end), the body 10 and 90 ° are rotated, together with the body 10 the fixed gear is rotated jQtCK 22, skolz along the radial groove of the guide 21. After rotation of the body 10 relative to the axis 18 and 90 ° (vertical position), the bottom of the disk 22 coincides with the plane of the guide 21 and the body 10 progressively; It goes down, with the housing 10 externally entering the surface. . centering ring 24 and centered therein.

In the final 10th position conclusions 6. radio element 9 enters the printing holes

board, and the axis 18 interacts with the pawl 23, which holds the axis 18 in the lower position. . .

In the second stage of operation, the rack 17 moves upward, turning gears 16, 15, 14 and gear 11 into reverse CTOpd. When this pusher 9 departs from the jaws 5, which is. These are consumed by the spring 3, releasing the leads of the radio element 7. At the same time, the ejector 12, slipping over the slot cam of the housing 10, moves the visa, the radio element up to the stop in the state. The trimming mechanism (lie and evidence) cuts the leads and bends them to the printed circuit board. After the final rask | From the jaws 5, the protrusion of the rail 17 acts on the pawl 23, which releases the axis 18. The cortus 10 under the action of the rail 17 moves upward until it stops, and as the rail 17 continues to move, the wheel 14 rotates on the axis 18 and the body 10 turns position

To switch to the installation of other types of radioeleite on axis 2, other mechanisms 25 or 26 radio elements may be installed.

The proposed device allows to increase the density of installation of radio elements, for the account of the reduction of the zone between radio elements, necessary for the removal of the jaws of the mechanism of capture of radio elements.
