Description

The invention relates to the manufacture of semiconductor devices, in particular to assembly equipment, in which automatic devices for non-surgical transport and supply of products to the work area are used.

A known machine for loading and moving radioelements in which a clamshell mechanism is used for conveying products, comprising fixed and movable rulers on which the transported articles are based (ceramic bases of resistances), driven by cams, kinematically reflected with pushers performing vertical lifting and horizontal moving rulers 1.

The disadvantage of this device is the possibility of loss of orientation of the products when transferring to the next position due to inertial forces during the operation of the clamshell mechanism.

The closest is a device for moving radioelements, containing: a common feeder, a transporting mechanism connected to a drive in the form of a clamshell with grippers, an orientator and an accumulator fSj ..

In this device, transportable articles from a cassette or magazine are individually loaded onto the guides of the working table and moved by the grippers of the grab bar. The grippers lower and enter the spaces between the products and move from the drive to the working stroke (feed step), then the grips are raised and retracted to the initial position (idle), after which the product is fixed to the working position. Due to the fact that the grab plate is moved to the working (idle) stroke and the lifting (lowering) of the grippers is carried out by a single drive, then a more extended stroke than the positioning step of the products is provided to effect the move to the grab film. This is necessary in order to withdraw the grippers from the zone of contact with the products, as well as bring them into contact.

The disadvantages of the known device are the low accuracy of movement due to the inertial overrun of products during high-speed feed at the moment of lifting the clamshell grabs and low reliability of the device, as during over-runs of products the mechanism may malfunction. The purpose of the invention is to increase the reliability of the device. This goal is achieved by the fact that the device for moving radio elements, comprising a feeder, a transporting mechanism in the form of a clamshell with grippers, an orientator and a drive connected to a drive, is equipped with a radioelement separation mechanism according to a step kinematically connected to the clamshell of the transporting mechanism, while the orientator rigidly mounted between the grab clamps. Also, the radioelements separation mechanism in a pitch is made in the form of a lath with protrusions mounted parallel to the grab bar of the transport mechanism, and the orientator is made in the form of an abutment with orienting protrusions. Figures 1 and 2 show the devices in the projections of the projections, general view; in FIG. 3, section A-A in FIG. 1 in FIG. 4, fragments of the working positions of the batten of the separating mechanism, the clamshell bar and the orientator. A device for moving radio elements contains} (sieve body 1, feeder 2, cutter 3, guides 4-6, receiving device 7, orientation 8, transporting mechanism 9 with a drive. 10, separation mechanism 11 in a step with drive 12 and a drive. 13. The transporting mechanism 9 consists of a drive 10, a crank mechanism 14, a movable carriage 15 including a pivot axis 16 with struts 17 and a bar 18, a clamshell bar 19 with grippers 20 and an orientator 21 made in the form of an emphasis with orienting lugs A and B. Mechanism 11 divided by pitch including the actuator 12, on the shaft of which is fixed the cams 22 and 23, as well as the levers 24 and 25 forming the cam bolshes; the chyuchnaya system, swinging the platen 26, tgu 27, the lever 28, the bracket 29, the dividing rail 30, mounted parallel to the clamshell plate 19. The drive 12 of the separation mechanism 11 is kinematically connected through the lever 24 to the bar 18 to the clamshell 19, and through the lever 25 to the bracket 29 and the rail 30 to the projections of the separation mechanism 11. The separation mechanism bar 26 is connected to the lever 31 carrying the clamp 32. This communication ensures reliable orientation and fixation of the product body at the working position and eliminates misalignment between the clamshell 19 and the rail 30. The guide 4 and the extreme end of the rail 30 form the pocket of the receiving device 7. The drive 13 is installed obliquely on the housing 1. The device operates as follows. When turning on 1; 1 drive 10 of the transport mechanism, 9 and drive 12, the separation 11, in a sequence defined by the order of operation of the device, the mechanisms are set to their original position, i.e. the clamshell-19 is in the extreme left position, the claws 20 are retracted from the guide 5, and the rail 30 with its teeth overlaps the guide 5 to the axis of movement of the radio elements. In the feeder 2 load radio elements (for example, Dip type casing), pre-oriented in the direction of feed. The Start command includes a cutter 9 and the body of the product under the action of gravitational forces slides along the guide 4, all the way into the rail 30. And sinks into the pocket-receiver 7. Then the control unit (not shown) turns on the drive 12 of the separation mechanism, which through the cam 23 , the lever 24, the bar 18 rotates the axis 16 and together with it the grab bar 19, the grippers 20 of which slide onto the guide and grab the body of the radio element that is in the receiving device 7. After the grips 20 have gripped the radio element drive 12 through the cam 22, snarling 25, the bar 26, the tug 27, the lever 28 deflects the bracket 29, the rail 30 slides back and releases the guide 5. At the same time, the bar 26 lifts the lever 31, and with it the clamp 32. The drive 12 of the separation mechanism turns off, the drive starts 10 and through the crank mechanism .14 moves the carriage 15, and together with it the grab bar 19 with the grippers 20 and the radio element to the step. The drive 10 of the transport mechanism 9 is turned off, the drive 12 of the separation mechanism 11 is turned on by the action of the cam 22 lever 24 return The separator rail 30, which grips the radio element with its side faces, protects from further movement and preliminary orientation of it on the guide 5, lowers the clamp 32 and under the action of the cam 23, the lever 24 displays the claws 20 of the clamshell 19 of engagement with product1 {em. The actuator 12 is turned off, the actuator 10 is turned on again, and the crank mechanism 14 retracts the carriage 15 with the clamshell 19 to the initial position. The radio element moves to the step (movement cycle). The movement cycle is carried out automatically.

With the repetition of the cycle of movement, the clamshell 19 successively moves the radioelements 2 coming from the feeder along the guide 5 to the working zone.

In the working area, the rail 30, while moving, the side edges of the teeth align and press the radio element to the orienting lugs of the orientator 21, the lever 31 lowers the presser 32 and presses the radio element to the guide 5, fixing its oriented position. The actuator 12 removes the claws 20 of the clamshell 19 from engagement with the radio element, and then the actuator 10 returns it to its original position.

After processing (assembling) the product of the grab plate 19 again moves the radio element along guide 5 to drive 13, its last grip pushes the radio element onto an inclined guide 6 when moved, from which the radio element enters drive 13 due to gravitational forces.

Thus, the radio element is constantly in contact with the rake teeth of the separating mechanism or the claws of the clamshell, which eliminates the inertial overrun of radio elements during rapid movements, increasing their orientation accuracy and reliability of the device.

In addition, the radioelements located between the rake teeth of the separation mechanism retain their orientation when exposed to various kinds of vibrations acting on the device and random shifts during operation, which increases the reliability of operation.

Using the proposed design of the device for moving

radio elements in the assembly of integrated circuits will reduce the error in the orientation of products, improve the reliability of the device, and improve performance by increasing the speed of movement of radio elements. The device can be easily integrated into various assembling installations (for example, posad and crystals, unwinding of bridges, visual inspection, etc.).
