Description

DETAILED DESCRIPTION OF THE INVENTION The present invention may be supplied in bulk.
BACKGROUND OF THE INVENTION Component spraying relates to a machine feeding device for feeding unwired polarized electronic components, inspecting the components for defects and orientation and correct orientation.

Machines are already known for automatic mounting of components in sequence or at the same time, in which components can be used as bulk materials; Only component A, which had a small size, could be processed. However, today there are polarized components on the market, such as diode-P and tantalum capacitors, so-called MELFs. In order to process such components, mounting requires correct orientation of each component when feeding into the spatula F.

The device disclosed in U.S. Pat. No. 3,344,900 includes a tip orientation control switching mechanism for a tip positioner.

This device serves to supply chip-like transistors and diodes to printed wiring boards, and has a mechanism for inspecting the components for defects and correct orientation. Furthermore, a mechanical contact for detecting the spherical connection point of the component and an electrical switching contact triggered by the contact to correspondingly rotate the component by 900 degrees or more. It is provided.

In this known device, the integrity of the components is in any case corrected (9) only by checking the spatial position of the contacts. Also, the above specification does not describe a mechanism for bringing the spherical contact of the chip downwardly into the required position. According to the same specification, a defect detection mechanism inspects not only the correct seating of the chip at the vacuum needle, but also the undamaged profile and contacts of the chip. However, no testing of the electrical functionality of the chip is performed here. It cannot be said that said specification provides a satisfactory solution for processing MEL F.

That is, the MELF has a cylindrical shape, or in some cases a vertically elongated rectangular parallelepiped shape, and the connection part is a metal cap at both ends, whereas the solution in the above specification is a chip, that is, a flat rectangular parallelepiped shape. It is limited to processing sheet metals with a rectangular profile and a spherical connection in each flat surface.

Therefore, it is an object of the present invention to carry out the JO orientation of the components between the bulk storage container and the mounting head during the supply of components of the type mentioned above, and to Detection of defective components and their removal, as well as installations that cause incorrect polarization, can be avoided in a simple manner by replacing components in the head. The purpose is to provide equipment.

In order to solve this problem, in the configuration of the first invention,
An apparatus provided with a mechanism for testing the electronic functionality and polarity of a component and a mechanism for feeding the tested component in correct polarity and orientation, the mechanisms having the configuration described below. A feed shaft or a corresponding feed pipe consisting of sections, i.e. having at least at its lower end a rectangular cross-section corresponding to the shape of the component, is connected to a general-purpose bulk container, and the feed shaft or The narrow side of the supply tube has at least two outputs f111 which contact each component one after the other via electrodes and emit output signals in connection with electrical inspection tests, and which connect the supply shaft or the supply At the outlet of the tube, a pivotable support surface is arranged in a plurality of inclined positions, such that the component is measured when it is fully supported by the support surface, and a tongue attached to the support surface is arranged. Two electromagnets are assigned to the body, each time one of the two magnets being actuated by the output of the test and control unit, so that the support surface can be moved from its rest position to one of the two possible positions. Two channels connected in a heart-shaped manner to each side of the support surface are connected to the tested component, which is pivoted around the pivot axis on one side and thus always has the correct polarity on the front side. or via either a hose, the attachment is routed to a pipe leading to the unit, and the electronic test and control unit has a third output side, on which output side. A third electromagnet is connected, which electromagnet is activated when a defect is detected in the component to cause the component to be gravitated from the support surface to the reject container approximately perpendicular to the pivot axis. or with the aid of a pressurized air nozzle, in which case the support surface is provided with a second pivot axis type perpendicular to the pivot axis, and a third electromagnet is Another tongue is fixed perpendicularly to the tongue, and the tube leading to the unit is placed over the receiving hole provided in the receptor or chisel turn. terminating diagonally in the connecting member that is
The component is supplied via the receiving hole to the substrate or printed wiring board on which it is mounted, in which case the connecting member has dimensions slightly smaller than the diagonal length of the component to be processed. It has a guideway.

In order to solve the above-mentioned problem, the second aspect of the invention includes a mechanism for testing the electronic functionality and polarity of the component, and a mechanism for supplying the tested component with the correct polarity and orientation. are provided, and these mechanisms consist of device parts having the configuration described below, i.e. a supply having (13) at least at its lower end a rectangular cross section corresponding to the shape of the component. A measurement in which a shaft or a corresponding supply pipe is connected to a general-purpose bulk container and an electrical test is carried out by contacting each component one after another via an electrode on the narrow side of the supply shaft or supply pipe. an electrical test and control device connected to the measuring electrode, the test and control device having at least two outputs for producing output signals related to the detected polarity and the test; At the outlet of the supply shaft or supply pipe, a pivotable support surface is arranged in a plurality of inclined positions, on which the component falls after the measurement, and the support surface In order to avoid falling of the components in pieces in the rest position, two electromagnets are assigned to the end of the support surface on which the components fall after inspection. Either of the magnets is actuated by the output of the test and control unit, causing the support surface to pivot from its rest position into one of two possible tilted positions, thereby ensuring that the correct polarity is always forward. The inspected components provided in f111 (14) are attached to the unit by removing one of the two passages or hoses connected to both sides of the support surface and connected in a heart shape. ), and if a defective component is detected, both magnets are actuated simultaneously by the control unit, tilting the support surface and causing the component to fail. An electromagnet is connected to the support surface so that it can fall into the reject container, in which case an impulse flow from a pressurized air nozzle located correspondingly close to the component (111
The pipes acting on one side of the unit are adapted to impart the desired movement to the component, and are attached to
(A substrate or printed wiring board that ends diagonally in a connecting member disposed above a receiving hole provided in a receptor or a pattern, and a component is connected through the receiving hole to a board or printed wiring board where the component is connected to a plurality of parts.) in each case projecting approximately perpendicularly to the measuring electrodes, the connecting portions having a guide channel having a dimension slightly smaller than the diagonal length of the component to be treated. A rim is provided,
The component remains in contact with the edge until the measuring electrode is pulled back by a small amount in order to release the component after the component has been tested.

Next, we will discuss one point obtained by the configuration of the first invention: The components to be oriented in the correct direction are fed from a bulk container and placed horizontally on a support surface that can be pivoted in three directions. and the connecting camps of the components contact each other in an elastic NW! mounted insulated from each other on opposite sides near the end of the supply pipe. A test and control unit is connected which detects whether the A tongue attached to the support surface is attracted and the support surface is swung accordingly.If the component is defective, it is dropped into a reject container.

If there are no defects in the component, the supporting surface is
The vehicle can be selectively rotated in one of two directions. In this case, the component with the desired connection electrode on the front side is always slid into one of two channels, hoses or tubes connected to the support surface and connected to each other in a .

Both channels, hoses or tubes open into a tube which further leads the component, the cross-section of which is selected in such a way that the component does not turn over.

The front ends diagonally in a connecting member which supplies the component to a corresponding hole provided in the notch turn or receptacle. The dimension of the correspondingly designed guide channel in this connecting part is smaller than the diagonal of the component. By being configured in this manner, the component is prevented from flipping over and the desired orientation of the component is maintained.

In the feeding device according to the second invention, the measuring electrode holds the component reliably during the test and then releases it only by a slight return movement. It has a retaining edge that releases. After the test, the released component is placed on a support surface which is brought into one of three possible positions by two electromagnets depending on the measurement result. Depending on the inclined position of this support surface, the component slides with the desired polarity or orientation via the branch connected to the support surface into the tube leading to the branch. When the supporting surface is lowered in parallel, the component is transferred to the reject container under the action of a compressed air impulse flow.

Next, an implementation f11 of the present invention will be described with reference to the drawings.

Figures 1A, 1B and V10 show the automatic installation of small structural components with polarity and no lead wires. One embodiment of the device is shown. Upstream of this supply device is a storage container for the components to be handled as bulk materials. The supply pipe 1+'i has, at least at its end, a rectangular cross section that is somewhat larger than the dimensions of the cylindrical component 2. At the end of the supply pipe having a cross section like this (]8), the component 2 has two measuring electrodes 3 mounted insulated on the supply pipe 1.
, 4, in which case the component 2 is supported by the upper side of the support surface 7. Surface measurement electrode 3
, 4 are connected to an inspection and control unit (not shown). The test unit detects the functionality and polarity of the component 2, and the output of the test unit causes the control unit to energize one of the two 'FHUf & stones 5, 6 to activate the tongue 8 of the support surface 7. attract. As a result, the tongue-shaped body 8 is moved to the pivot point 1 as shown in FIG. 1B or FIG.
It can be rotated around 6. As a result, component 2
slides towards either side into the opening of one of the two hoses 13, 14 which are connected in a t-shape. Therefore, the tube 15 connected to both hoses 13, 14
The component 2 with the desired electrodes on the front side is always reached, and the installation is carried out by gravity through this tube 15 via the head 22, with a chisel turn placed on the base plate 24 on which the component 2 is attached. 23, a square notch 25 is reached. The hollow chamber of the head 22 into which the tube 15 opens is designed in such a way that the entering component 2 does not tip over into an undesired position and polarity. This is achieved in that the dimension of the cavity, including the recess 25 adjoining it, is smaller than the diagonal of the component 2.

3A, 3B and 30 show an embodiment of a feeding device capable of eliminating non-functional or defective components 2.

FIG. 3A shows the feed device in the starting position as in FIG. 1A, but without the heart-shaped hoses 13,14. 3B and 3C show the feeding device shown in FIG. 3A rotated through 90 DEG. This shows the circular cross-section of the component 2 and the further tongue 10 mounted at right angles to the tongue 8. The tongue 10 is attracted by the electromagnet 1 when a defective component 2 is detected. This attracted state is shown in Figure 3C. In this case the support surface 7
is caused to move in a counterclockwise direction about the pivot point 9, and the component 2 falls into the reject container 12. In this case, the air shock stream blown out of the compressed air nozzle, as shown in FIG. 3C, facilitates rapid and precise movement.

FIG. 4 shows an embodiment of the supply device according to the second invention.

The supply pipe 30 has two measuring electrodes 32.33 between which the component 31 is held for testing purposes. How it is held is that the measuring electrodes 32, 33 have a small bent edge to hold the component 31 and are elastically crimped in a manner not shown for testing. I am forced to do it. At the end of the test, the surface measuring electrodes 32, 33 are connected to the supply pipe 3 by a small amount.

brought to you. In this one inclined position, the component 34 slides into one of the two hoses 36, 37. In this case, the desired electrode detected on the basis of the measurement is on the front side. Both hoses 36 and 37 are shown in Figure 1A,
As shown in FIGS. 1B and 1C, it is connected in a heart shape and is further connected to a subsequent tube 15. From this tube 15, a correctly polarized or correctly oriented component 34 reaches the mounting head, for example as shown in FIG. 2 and described above.
