Definitions
- the invention relates to a method for changing the position of electronic components, for example of a chip, the component provided, for example on a film or in matrix-like containers or in or on a tool, being picked up, held, transported and on at a pick-up position by a pick-up tool Storage position, for example at an intermediate position or
- Processing position is stored or is held ready in a further receiving position for a further position change.
- the invention further relates to a device for carrying out the method.
- No. 4,875,285 A discloses methods according to which the component is picked up with the aid of a special mounting head, a so-called turret, which can pick up several components one after the other, that is to say sequentially, at the component receiving position.
- the time-consuming travel path to the processing position, in particular to the bond position is then carried out simultaneously with all the components that have been picked up.
- the components are stored individually or sequentially. This will make the Run through the path from the component receiving position to the processing or bonding position for several chips only once.
- the disadvantage of this method is that both the component pick-up process and the component storage are sequential and therefore slow.
- such a turret head is designed so that when the turret is rotated, the holding tools are always ready at the same xy position for holding the component.
- a positioning device movement is necessary for each component. The same applies analogously to component storage. This travel path therefore also leads to considerable loss of time.
- the object of the invention is to provide a method of the type cited at the outset which, on the one hand, avoids the above disadvantages and, on the other hand, permits more rational production, with an at least equivalent quality standard.
- the method according to the invention is characterized in that at least two components are picked up at the same time in at least one receiving position and / or are deposited simultaneously in at least one depositing position, wherein in the case of intermediate positioning of the components, this intermediate position is both the depositing and the receiving position.
- the component can be fed in one step, but feeding with the interposition of at least one intermediate position is also possible.
- the same tool can be used to feed to the processing position, or the intermediate position can be switched to another pick-up tool.
- the relative arrangement of the components to one another is changed between the receiving position and the storage position. This measure advantageously allows the component or chip to be deposited at the processing or bond position with a pitch that is independent of the grid division of the components or chips at the component receiving position.
- the division dimension mentioned is the relative distance between the individual chips.
- the term changing the relative arrangement of the components to each other also includes twisting the components. In this way, it is possible to respond flexibly to production-related grids.
- the components picked up at the pick-up position are stored or held ready at an intermediate position at the same time and picked up again with a changed relative position to one another, in groups or individually.
- the change in the relative position of the components to one another can take place in the intermediate position. If, for example, the components are kept ready in the intermediate position with a receiving tool, the transfer of a grid on the component holder to another grid on the component tray can be achieved by changing the components to another
- Each recording tool has its own, in particular fixed, grid, the grid being changed by appropriate group-based recording of the components.
- the advantage of this procedure is that the chip can be picked up from an intermediate position much faster than, for example, the chip pickup from a carrier film. This results in a considerable gain in time for the parallel chip removal from the film with subsequent sequential transfer compared to the sequential removal from the film.
- the components which are picked up together at the pick-up position, in groups or individually, are placed at the depositing position together or in groups or kept ready.
- a grid transfer is achieved by sequentially placing groups of components at the processing position.
- the relative arrangement of the components during the pick-up is changed by changing the relative position in the pick-up tool, if necessary during transport.
- This advantageous embodiment uses the transport route or the transport time for changing the relative position of the components to one another. A further increase in the number of cycles can thus be achieved.
- the relative arrangement of the components during the recording is changed by changing the relative position in the intermediate position.
- This can be carried out, for example, via movable storage areas for the individual components, so-called microactuators, provided at the intermediate position.
- the components and / or the relative arrangement of the components to one another are measured, in particular optically, on the holding tool and / or in the intermediate position. If there are several components on one recording tool, they can all be measured simultaneously with one camera.
- the components can be measured from above with the substrate camera at once or by moving the camera. But it is also quite conceivable that with the help of a special recording tool, a so-called transparent flip tool, the components can also be inspected from below using the rear-side camera.
- the position and / or the angle of the components relative to one another and / or the components relative to another coordinate system can be determined by the image processing software. A change in the relative position of the components to one another can thus be automated.
- the components are simultaneously punched out or raised with needles when they are provided on a film when they are lifted off with the pick-up tool from the rear. This enables the chips held by the holding tools to be detached from the carrier film without any problems.
- each component is removed with its own arrangement of needle and a suction needle or gripper provided in the receiving tool. This ensures parallelization in the admission process through individual, parallel support.
- each pick-up tool or each suction needle or gripper is adapted to the individual height of the component. This can ensure that manufacturing-related height tolerances, such as, for example, of recording tools or chips, are compensated for and that the entire arrangement of components is properly picked up and stored.
- the object of the present invention is also achieved by a device for carrying out the method.
- the device according to the invention for carrying out the method is characterized in that at least one receiving tool is provided, which consists of at least two suction needles or grippers.
- at least one receiving tool is provided, which consists of at least two suction needles or grippers.
- the position and / or the angle of the suction needles or grippers provided in a holding tool can be changed relative to one another.
- the relative arrangement of the components relative to one another can be changed between the receiving position and the storage position.
- This can be achieved, for example, with an umbrella-like mechanism.
- the suction needles or the grippers are connected to a central guide linkage via movable connections. When this mechanism is opened, if necessary during the travel path, the radial distance changes and thus the grid division of the components specified during the recording.
- At least one suction needle or a gripper is movably and / or rotatably mounted in the receiving tool.
- the individual suction needles or grippers can of course also change their distance from one another by shifting in one plane. It may also be possible to twist the suction needles or the grippers.
- the receiving tool is arranged in a positioning device.
- Positioning devices are known per se, so that there is no need to go into them in detail.

- the simultaneous acceptance of several components can also be realized with a flip tool.
- This flip tool can also be scalable in at least one dimension. The components can be processed further from the flip tool, i.e. they can be removed individually or simultaneously from the pinball machine with a fixed or scalable pick-up tool and brought to the processing or bonding position with or without intermediate steps.
- the holding tool places the components at an intermediate position, the position and / or the angles to one another being changeable.
- the components can be placed in the intermediate position on a clipboard that can align the components.
- a clipboard that can align the components.
- So-called micro-actuators that is to say movable storage surfaces, which align the components in position and angle with respect to one another and / or in total with another coordinate.
- each suction needle or gripper or needle can be adjusted to the height of the component to be picked up.
- the removal needles can be mounted on springs and / or the removal tools can be sprung.
- the receiving tool and / or the film area on which the components to be removed are arranged can be heated.
- the adhesion of the components to the film can be locally reduced for special types of film and the quality of the component acceptance can thus be increased.
