Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electronic component manufacturing apparatus that performs various types of process processing on an electronic component, and more particularly, to an apparatus and a method for driving and controlling an electronic component holding unit that holds an electronic component.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, electronic components such as semiconductor elements have been manufactured by sequentially performing a plurality of processes such as electrode cutting, electrode processing, electrical property measurement, marking, appearance inspection, tape packaging, and the like. As an electronic component manufacturing apparatus that performs such various process processes, for example, a plurality of process processing mechanisms are sequentially arranged between an electronic component carry-in unit and an electronic component carry-out unit, and individually hold a plurality of electronic components. There is an electronic component manufacturing apparatus of a type in which a plurality of electronic component holding means are sequentially moved to a plurality of process processing mechanisms by a transport mechanism to sequentially perform a plurality of process processes.
[0003]
An outline of the operation in this type of electronic component manufacturing apparatus is as follows. First, the electronic component is received from the electronic component loading section by the electronic component holding means, and is transported to the process processing mechanism by the transport mechanism. When the electronic component reaches the process processing mechanism, the transport is stopped, and the electronic component is subjected to a predetermined process by the process processing mechanism. After the completion of the process, the electronic component is held by the electronic component holding means and transported to the next process processing mechanism. By repeating this operation, the electronic components are sequentially subjected to predetermined processes, and the electronic components after all the processes are carried out from the electronic component carrying-out section.
[0004]
Also, in this type of electronic component manufacturing apparatus, the processing position of the electronic component to be subjected to the process processing by the process processing mechanism is determined from the transport path of the electronic component so that the electronic component does not collide and be damaged during transportation. It is provided vertically or horizontally separated. Therefore, in order to perform the process on the electronic component by the process processing mechanism, it is necessary to move the electronic component from the transport position on the transport path to the processing position by the process processing mechanism, and to return to the transport path after the completion of the process processing.
[0005]
In order to move the electronic component between the transfer position and the processing position in this way, of the electronic component holding means that is moved by the transfer mechanism, a portion that holds the electronic component is a movable holding portion, and the movable holding portion is moved. There has been proposed an apparatus in which a holding means driving mechanism for causing the electronic component to be held is provided on each electronic component holding means or each process processing mechanism side (for example, see Patent Documents 1 and 2).
[0006]
Conventionally, a holding means driving mechanism for moving a movable holding section has been configured using means such as a cam, a lever, and a rod, and all holding means driving mechanisms have a constant timing, a constant moving amount, and a constant moving speed. Is controlled. For example, in Patent Document 1, a cam mechanism is adopted as a holding means driving mechanism for driving a suction nozzle which is an electronic component holding means, and this cam mechanism is interlocked with a turntable which is a transport mechanism, so that the turntable is driven. A configuration is described in which the suction nozzle is moved up and down in conjunction with the operation. Patent Document 2 discloses a configuration in which a suction nozzle is moved up and down by a linear motor provided separately from a direct drive motor that drives a turntable.

[0008]
[Problems to be solved by the invention]
As described above, in the related art, the holding unit driving mechanism that moves the movable holding unit of the electronic component holding unit is controlled at a certain timing with a certain amount of movement and a certain moving speed. Therefore, the moving time of the electronic component between the transport position on the transport path and the processing position where the process is performed by the process processing mechanism is constant. Further, in general, when performing step processing sequentially while performing intermittent conveyance, the stop time in each step processing mechanism is constant. Therefore, if the moving time of the electronic component between the transfer position and the processing position is constant, the step processing is not performed. Time has to be constant.
[0009]
As described above, since the process processing time is constant, among the plurality of processes, in the process requiring time, the moving time between the transfer position and the processing position is shortened to increase the productivity. There has been a problem that it is not possible to perform a flexible process such as preventing a defect from occurring by elongating a moving time. Also, in a process that requires positional accuracy, in order to avoid errors due to vibration from the transport mechanism, after the transport mechanism stops, it is necessary to move the electronic components to the process position after the vibration has become sufficiently small to increase the positional accuracy. Although desirable, such flexible processing could not be performed.
[0010]
On the other hand, when performing a plurality of steps sequentially, the load required for each step may be different. For example, in a process of cutting and processing an electrode of an electronic component, a large load is required to fix the electronic component, but a very large load is not required in the electrical characteristic measuring process. In addition, almost no load is required for tape packaging, marking, and appearance inspection processes. However, in the conventional apparatus as described above, the load for fixing the electronic component by the holding means driving mechanism is constant over a plurality of steps, so the electronic component fixing load is controlled for each step. In a process that does not require a large load, there is a problem that a flexible process such as preventing a defective product from being generated by performing the process with a small load cannot be performed.
[0011]
Further, in an electronic component manufacturing apparatus provided with a plurality of transport mechanisms configured to sequentially deliver electronic components as a transport mechanism, one electronic component such as a process of delivering electronic components between the transport mechanisms is used. In a process in which the electronic components are simultaneously held by the electronic component holding means, there is a problem that a greater impact is applied to the electronic components than in a normal process, and the possibility that defective products are generated increases. Therefore, in the electronic component manufacturing apparatus provided with such a plurality of transport mechanisms, the moving speed of the entirety of the plurality of electronic component holding means is set to a constant moving speed within a range that does not cause a defect in the delivery process between the transport mechanisms. Inevitably, the processing speed of the entire apparatus is limited, so that there is a problem that improvement in productivity is limited.
[0012]
Further, as described above, in a conventional electronic component manufacturing apparatus in which the entire electronic component holding unit has a constant moving time, the change of the moving amount and the moving speed due to the change of the thickness of the electronic component, the shape of the electrode, etc. There was a problem that it was not easy to cope with multi-product production.
[0013]
The present invention has been proposed to solve the above-described problems of the related art, and has an object of moving time, moving amount, moving speed, moving timing between a transfer position and a processing position of an electronic component. , Load, etc., can be set optimally for each process, and the amount and speed of movement can be easily changed according to the change in dimensions of electronic parts, thereby improving the productivity and quality of electronic parts. An object of the present invention is to provide a drive control device and method of an electronic component holding means which can contribute and can easily cope with multi-product production.
[0014]

It is like that.

And moving speed can be easily changed.

Further, the turntable 13 is horizontally disposed above the plurality of process units 2 arranged in an arc shape so as to be separated from the process unit 2 and to overlap the process unit 2 on the outer periphery thereof. A plurality of holding units 12 are arranged on the outer periphery of the table 13 at the same intervals as the plurality of process units 2.
[0030]
In this case, as shown in FIG. 2, when one holding unit 12 overlaps with one process unit 2, the other holding units 12 overlap with any one of the process units 2. And is arranged on the outer peripheral portion of the turntable 13. More specifically, as shown in FIG. 1, the plurality of process units 2 include a process unit 2 a that performs a process process on the electronic component 3, and the center of the process unit 2 a on the horizontal plane is the turntable 13. And are arranged so as to be positioned at equal intervals on one coaxial circle. The plurality of holding units 12 are arranged such that the centers of the nozzle tips 11a of the suction nozzles 11 on the horizontal plane are positioned at equal intervals on a circle where the center of the process processing unit 2a of the process unit 2 on the horizontal plane is located. It is arranged in.
[0031]
Although only two process units 2 and two holding units 12 are shown in FIG. 1 from the viewpoint of simplification of the drawing, in practice, as shown in FIG. Many process units 2 are arranged in the direction, and many holding units 12 are also arranged on the outer periphery of the turntable 13. As shown in FIG. 1, the direct drive motor 14 is disposed coaxially below the turntable 13 so as to directly drive the turntable 13.
[0032]
On the other hand, as shown in FIG. 1, the plurality of drive units 15 are provided corresponding to each of the plurality of process units 2, and contact the upper end portion of the suction nozzle 11 of the holding unit 12 to move the suction nozzle 11. An operation rod 15a for pushing down and a drive unit 15b for driving the operation rod 15a are provided. The plurality of drive units 15 are arranged above the turntable 13 so as to be separated from the transport path of the holding unit 12 and to overlap the corresponding process units 2 via the turntable 13, respectively. It is fixed integrally with the process unit 2 by the connecting portion 15c.
[0033]
Here, the plurality of drive units 15 raise and lower the suction nozzle 11 between the upper position and the lower position by vertically moving the operation rod 15 a by the drive unit 15 b, and hold the suction nozzle 11 at the nozzle tip 11 a of the suction nozzle 11.

[0037]
On the other hand, the plurality of holding units 12 are provided with springs 16 for pushing up and returning the suction nozzles 11 from the lower position to the upper position when the operation rod 15a of the drive unit 15 returns downward. The spring 16 corresponds to a drive source for return in the present invention.
[0038]
[2. Operation of Basic Embodiment]
The operation of the holding unit drive control device 1 of the present embodiment having the above-described configuration is as follows.
[0039]
First, in a state where the plurality of electronic components 3 are held by the suction nozzles 11 of the plurality of holding units 12, the plurality of electronic components 3 are sequentially conveyed to the plurality of process units 2 by rotating the turntable 13. When each holding unit 12 holding the electronic component 3 reaches each stop position corresponding to each process unit 2, the turntable 13 is stopped.
[0040]
In this case, the center on the horizontal plane of the suction nozzle 11 of each holding unit 12 at each stop position corresponding to each process unit 2 is the center of the process unit 2 on the horizontal plane, and the drive corresponding to the process unit 2 The operation rod 15a of the unit 15 overlaps the center on the horizontal plane. That is, the suction nozzle 11 of each holding unit 12 at each stop position can be driven by the operation rod 15a of each drive unit 15.
[0041]
Therefore, from such a state, in each drive unit 15, as shown in FIGS. 4A to 4C, by moving the operation rod 15 a up and down, the electronic component 3 is transported by the turntable 13. It is moved between the upper transport position and the processing position on the processing section 2a of the processing unit 2.
[0042]
That is, in each drive unit 15, first, the suction rod 11 is pushed down from the upper position shown in FIG. 4A to the lower position shown in FIG. 4B by lowering the operation rod 15a by the drive unit 15b. By this operation, the electronic component 3 held at the nozzle tip 11a of the suction nozzle 11 is moved from the transport position on the transport path by the turntable 13 to the processing position on the process processing unit 2a of the process unit 2, and the process unit 2 Can be passed to
[0043]
Then, after each electronic component 3 is subjected to a process process by each process unit 2, in a state where each electronic component 3 is held by the suction nozzle 11 of each holding unit 12, in each drive unit 15, the operating rod is driven by the drive unit 15 b. By raising 15a, the suction nozzle 11 is pushed up from the lower position shown in FIG. 4B to the upper position shown in FIG. As a result, the electronic component 3 held at the nozzle tip 11a of the suction nozzle 11 is returned from the processing position on the process processing unit 2a of the process unit 2 to the transport position on the transport path by the turntable 13.
[0044]
In the present embodiment, the drive control pattern of the suction nozzle 11 by the drive unit 15 when the holding unit 12 is stopped, that is, the movement time, the movement amount, the movement speed, and the movement between the upper position and the lower position of the suction nozzle 11. The drive control patterns such as the timing and the load are individually set for each process according to the process unit 2 corresponding to each drive unit 15 as described above.
[0045]
For example, assuming that the drive control pattern of the suction nozzle 11 in the process unit 2 that performs the first process is P1, the drive control pattern P2 in the process unit 2 that performs another second process does not correspond to the drive control pattern P1. It is set independently without any restrictions. Accordingly, for each process, the delivery time of the electronic component 3 and the process time determined in accordance with the stop time in the process unit are freely set within the stop time of the holding unit 12. Further, a load for fixing the electronic component 3 on the process unit 2 via the holding unit 12 by the drive unit 15 is also freely set according to each process.
[0046]
The movement of the holding unit 12 to each stop position by the rotation of the turntable 13 as described above, the movement of the electronic component 3 to the processing position, and the return of the electronic component 3 to the transport position are repeated, whereby each A plurality of processes by the plurality of process units 2 can be sequentially performed on the electronic component 3.
[0047]
[3. Effect of Basic Embodiment]
The effects of the holding unit drive control device 1 of the present embodiment as described above are as follows.
[0048]
First, according to the present embodiment, a plurality of holding units stopped at the stop positions corresponding to the respective process units can be driven and controlled by independent and individual drive control patterns by the drive units individually provided for the respective process units. Therefore, it is possible to optimally adjust the movement between the transfer position and the processing position when the electronic component is delivered for each process.
[0049]
That is, the moving time, moving amount, moving speed, moving timing, load, and the like between the transfer position and the processing position of the electronic component can be optimally set for each process, so that the productivity and quality of the electronic component can be improved. it can. In addition, since each holding unit can be individually controlled independently, it is easy to change a moving amount and a moving speed according to a change in size of an electronic component, and it is easy to cope with multi-kind production.
[0050]
Further, according to the present embodiment, as shown in FIG. 3, a device optimal for driving the electronic component holding means can be easily realized by freely using a drive source and a drive mechanism to which the existing technology is applied. be able to. Among the combinations of the driving source and the driving mechanism as shown in FIG. 3, those which are particularly effective include direct drive by a linear motor, a combination of a rotary motor and a rack and pinion, and a combination of a rotary motor and a ball screw. , A combination of a rotary motor and a lever, and the like. However, the effects of the present invention, in particular, the effects in controlling the moving amount and the moving speed can be sufficiently obtained even in a drive unit having other configurations.
[0051]
Furthermore, since the speed at which the electronic component is returned from the processing position to the transport position can be generally maintained at a constant speed regardless of the process performed by the process unit, the use of a spring as a drive source for the return allows the electronic component to be returned. The variable control for the movement of the components is only control in a single direction from the transport position to the processing position by the feed drive source, so that the control configuration of the drive source can be simplified.
[0052]
Furthermore, when a drive mechanism of the same standard and a feed drive source of the same standard are used as a plurality of drive units, the same standard spring can be used for the return drive source, so that The drive configuration can be unified and simplified.
[0053]
[4. Other Embodiments]
Note that the present invention is not limited to the above-described embodiment, and various other various modifications can be similarly implemented within the scope of the present invention. For example, in the above-described embodiment, the movable holding unit of the electronic component holding unit is constituted by the suction nozzle, but the specific configuration of the movable holding unit can be freely changed. Also, with regard to the transport mechanism, a turntable is merely an example, and the present invention can be similarly applied to various transport mechanisms capable of transporting a plurality of electronic component holding means, and similarly excellent effects can be obtained. It is.
[0054]
In the above-described embodiment, the case where the holding unit 12 is raised by the driving force of the spring 16 has been described. However, the operating rod 15a is raised in a range of a speed smaller than the rising speed by the spring, and the rising speed is It may be controlled. Further, the holding unit 12 and the operation rod 15a may be connected by vacuum suction or mechanical means from the start of the descent to the completion of the descent, and the descent and the descent speed may be controlled by the drive unit 15.
[0055]
In the above-described embodiment, the drive unit 15 for driving the holding unit 12 is provided for each process unit 2. However, the present invention is not limited to this, and the drive unit 15 may be provided for each holding unit 12. For example, as shown in FIG. 5, it is conceivable that the driving units 15 are completely corresponded to the individual holding units 12 by, for example, fixing the driving units 15 integrally with the holding units 12 by connecting portions 15c.
[0056]
As described above, when the drive unit 15 is provided for each holding unit 12, optimal drive control for each process unit 2 corresponding to the stop position of the holding unit 12 may be performed according to the stop position of the holding unit 12. For example, if the drive control pattern at the first stop position corresponding to the process unit 2 performing the first process is P1, the drive control at the second stop position corresponding to the process unit 2 performing the second process is performed. By setting an optimal drive control pattern for each stop position with respect to the same holding unit 12 in such a manner that the pattern becomes P2, the same effect as in the above embodiment can be obtained.
[0057]
Further, the present invention is not limited to a production line using a single transport mechanism as shown in FIG. 1, but as shown in FIG. 6, a plurality of transport mechanisms (FIG. 6) configured to sequentially transfer electronic components. The present invention is similarly applicable to a production line using the middle turntables 13a, 13b), and similarly excellent effects can be obtained. In particular, when the present invention is applied to a production line using a plurality of transport mechanisms, the normal moving speed of the holding unit using the same transport mechanism during the process can be optimally set, while the holding unit is used between the plurality of transport mechanisms. It is possible to set the moving speed of the holding unit to be a delivery source and a delivery destination of the electronic component lower than a normal moving speed.
[0058]
As a result, in a production line using a plurality of transport mechanisms, it is possible to maintain high processing efficiency as a whole of the production line and reliably prevent the occurrence of defects due to impact at the time of delivery between the transport mechanisms. Therefore, the productivity and quality of electronic components can be improved. In this connection, if further mentioned in this regard, the present invention is not limited to the same type of transport mechanism as the plurality of transport mechanisms, and is similarly applicable to a case where a plurality of different types of transport mechanisms are combined. Yes, and excellent effects can be obtained as well.
[0059]
【The invention's effect】
As described above, according to the present invention, the electronic component holding units are individually driven by individually driving the holding unit driving mechanisms provided for each of the electronic component holding units or the process processing mechanisms by mutually independent driving sources.
