A supply unit that feeds electronic components with a wide projection surface in the horizontal plane toward the assembly position, such as axial lead taping components, which have a large number of radial lead electronic components secured to the tape. A supply unit that feeds electronic components with a wide projection surface in the horizontal plane toward the assembly position, such as radial lead taping components, and a supply unit that feeds electronic components with a wide projection surface in the horizontal plane toward the assembly position. The present invention relates to a taping component supply device that can be detachably attached to the top of the taping component supply device.

[Prior art]

In automatic electronic component assembly machines, a taping component supply device equipped with an intermittent conveyance device is used to supply electronic components to be assembled onto a printed circuit board to an assembly position below an assembly head. In this case, electronic components that are taped in a wide manner at a constant pitch such as axial lead electronic components and electronic components that are taped in a wide manner such as radial lead electronic components are sequentially placed using a ratchet wheel. Taping component supply apparatuses that include a plurality of types of supply units are often used. However, in conventional taped component supply devices in automatic electronic component assembly machines, the mounting base of the supply unit that supplies taped axial lead electronic components and the mounting base of the supply unit that supplies taped radial lead electronic components are separate. The maximum number of units that can be installed for each supply unit is determined, and these units are removably installed on the same mounting base, depending on conditions such as the type and quantity of electronic components to be assembled on the printed circuit board. Therefore, it is possible to properly select and arrange the ratio between the number of taping component supply units in the former case and the number of taping component supply units in the latter case, or to move each taping component supply unit to the rear of the insertion position according to the horizontal movement of a single mounting base. There is no system that can index and supply each electronic component to its supply position.

[Problems that ideas should solve]

As mentioned above, in the conventional taping component supply device, although the type and quantity of electronic components assembled on a printed circuit board are variously changed, the supply unit for supplying axial lead electronic components and the supply unit for supplying radial lead electronic components The maximum number of parts that can be installed with the supply unit that supplies components is a fixed number determined by each mounting base, so if there are many axial lead electronic components or radial lead electronic components that are to be assembled on a printed circuit board, and the other is few. However, since it is impossible to appropriately select the ratio of the number of units to be installed, there is a drawback that there is a lack of flexibility in terms of the ability to mount electronic components. Therefore, it is an object of the present invention to provide a taping component supply device that can overcome these drawbacks.

[Means of solution and action]

In view of the above-mentioned object, the present invention has a plurality of supply units that sequentially feed taped parts formed by arranging a large number of electronic parts onto a tape toward the assembly position of an automatic electronic parts assembly machine. In the taping component supply device, there is an axial lead electronic component supply unit (A component supply unit) that supplies taping components in a wide manner onto a supply stand that extends horizontally behind the assembly position, and a radial lead electronic component supply unit that supplies taping components to the width pin. Lead electronic component supply units (R component supply units) can be arranged on the supply table at intervals of mounting position widths determined in advance by positioning pins, and at this time, the mounting position width of the A component supply unit is equal to the R component supply unit. There is provided a taping component supply device characterized in that the width of the mounting position of the supply unit is an integral multiple or an integer ratio, and as described above, both supply units can be mounted on the same mounting base, and the width of the mounting position is Since the relationship is an integral multiple or an integral ratio, it is possible to easily increase or decrease the number of either supply unit installed as necessary, and to set the most effective number ratio with the same installation space. It is possible to attach supply units in an array.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

FIG. 1 is a schematic plan view showing the basic configuration of an electronic component automatic assembly machine equipped with a taping component supply device according to the present invention, and FIGS. 2 and 3 are respectively in the direction of the − arrow line in FIG. 1. FIG. 3 is a side sectional view showing the A component supply unit and the R component supply unit as seen from the front.

1, 2, and 3, a plurality of taped component supply devices 10 according to the present invention are installed in parallel on a mounting base 12 provided at the bottom of the back side of an insertion head 40 of an automatic electronic component assembly machine. has been done. The mounting base 12 is provided as a table member that can be moved in the lateral direction indicated by the arrow “S” (FIG. 1) with respect to the insertion position A directly below the insertion head 40. The electronic component supply unit 14 (FIG. 2) is a well-known electronic component supply unit 14 (FIG. 2) for supplying taped components in which axial lead electronic components are arranged and fixed to a tape at a constant pitch in a flat position in a wide state. A known R component supply unit 16 (third unit) is used for supplying taped components in which radial lead electronic components are arranged and fixed on tape at a constant pitch in a vertical position in a wide width state.
(Fig.) are configured so that a plurality of them can be placed in parallel, and these A and R parts supply units 1
4 and 16 are arranged side by side in the horizontal direction of the mounting base 12. In this case, the A component supply unit 14 is configured to supply the axial lead electronic components in a flat position, that is, in a wide position with each electronic component lying flat and the lead wires at both ends fixed with tape. On the other hand, the R parts supply unit 16
The configuration is such that the radial lead electronic components are supplied in a vertical position, that is, each electronic component is attached to the tape in a horizontal position with the lead wires facing downward. This allows the insertion operation to be performed smoothly by eliminating the need to change the posture when inserting the axial lead electronic component and the radial lead electronic component into the printed circuit board using the insertion head 40, which will be described later. As a result, as shown in FIG. 1, the A component supply unit 14 has a wide width determined by the spacing between the tapes to which the lead wires are fixed, and the R component supply unit 1
6, because the tape itself moves in a vertical position, the width could be made narrower.

In the illustrated example of FIG. 1, two wide A component supply units 14 are mounted, and a large number of narrow R component supply units 16 are mounted, but according to the present invention, the ratio of these units can be adjusted. It will become clear from the description below that a large number of supply units 14, 16 can be arranged on the mounting base 12 with a constant width even if the width is changed. Each supply unit 14 arranged on the mounting base 12
Alternatively, when the electrical components 16 are linearly aligned behind the insertion position "A", if the electrical components are intermittently and sequentially supplied toward the insertion position "A" in the direction indicated by the arrow "F", the insertion head 40 and A clinch head 50 disposed oppositely below the insertion head 40 cooperates with the insertion head 40 to automatically insert electronic components supplied onto a printed circuit board fed from the direction of arrow "T". In addition, when supplying electronic components in this example,
In the case of axial lead electronic components, the parts are temporarily placed in a standby position at the tip of the A component supply unit 14, and then the supply unit 14 itself is directed from the rear toward the insertion position "A" by the action of the cylinder device 52 (Fig. 2). The waiting electronic component is cut out from the tape, the lead wires at both ends are shaped into a shape suitable for insertion, and then inserted into a predetermined insertion hole of the printed circuit board. head 4
At the lower end of 0, there is a lead wire cutter, a lead wire forming tool,
A push-in head for electronic components is provided.

On the other hand, in the case of radial lead electronic components, R
The taped components are sequentially fed to the tip of the component supply unit 16 and are separated from the tape at the tip, similar to the taping components of the axial lead electronic components described above.
When it reaches the tip of the insertion head 40, it is carried from the tip of the supply unit 16 to the lowest end of the insertion head 40 by the transfer arm means 54 (FIG. 3) provided near the insertion head 40, and after being held, it is placed on the printed circuit board. inserted into. Note that a plurality of insertion heads 40 are held in a rotating turret 42 in advance in a manner that corresponds to the type of external shape of the electronic component to be inserted into the printed circuit board. The arrangement is such that a suitable insertion head 40 is indexed into the insertion position A by pivoting the pivoting turret 42. In addition, in FIGS. 2 and 3, the line 56 indicates a printed circuit board, and 58 indicates a case where each supply unit 14, 16 sequentially and intermittently supplies the corresponding taping parts in the direction of the insertion position. The driving part of the intermittent feeding mechanism is shown, and this driving part 58 is connected to the A component supply unit 14.
It also serves as the operating source for the intermittent feed mechanism 60 provided in the R parts supply unit 16.

Now, on the mounting base 12, the positioning pin 18
is removably installed in a pin hole 20 drilled on the mounting base 12, and the R component supply unit 16 for supplying radial lead electronic components is also drilled with a pin hole 21 so that the mounting position is always constant. A positioning pin 19 is provided in a removable manner. Then, each supply unit 14, 16 is installed at the mounting position determined by these positioning pins 18, 19.
For example, by being inserted and attached from the rear of the supply stand 12, it can be accurately attached to a predetermined attachment position. According to the present invention, the positioning pin 19 of the narrow R component supply unit 16
The pitch P ₁ of the positioning pin 18 of the wide A component supply unit 14 of the former is 2 compared to the pitch P ₂ of the
It becomes an integer multiple such as times, 3 times, etc., or 3/2 times, i.e.
Each unit is 1.
The width ratio of 4 and 16 is selected to be an integer multiple or an integer ratio. In the illustrated example, the relationship is P ₁ = 2P ₂ , and the pin holes 20 and 21 are all narrow pitches.
Perforated at P ₂ . Therefore, it is necessary to insert several types of axial lead electronic components due to the circuit design conditions of the electronic components to be inserted into the printed circuit board, and therefore, one A component supply unit 14 is prepared in addition to the two shown. When it becomes necessary to do so, remove the two left ends of the R component supply units 16 for radial lead electronic components, remove the positioning pins 19 from the pin holes 21, and perform the positioning for positioning the A component supply unit 14. By loading the pins 18 into the empty pin holes 21, it is possible to immediately increase the number of A component supply units 14. In addition, in the illustrated example, A parts supply unit 1
The reason why there are two units of A component supply unit 1 is because a well-known sequencer is used to arrange the axial electronic components in the order in which they were inserted and then re-tape the sequence tape.
This figure shows a case where the number of A-component supply units 14 is reduced by making it possible to supply A-components 14 at 4 times, and it is possible to make do with two A-component supply units 14, one with a wide tape interval and one with a narrow sequence tape. It is.

On the other hand, due to the circuit design conditions of the electronic components to be inserted into the printed circuit board, it was necessary to insert many types of radial lead electronic components, and therefore it was necessary to further increase the number of R component supply units 16 from the number shown in the figure. Sometimes, contrary to the above, the A component supply unit 14 is removed and the positioning pin 18 is inserted into the pin hole 2.
0, and instead use the pin holes 20 to attach the two positioning pins 19, and then attach the R component supply unit 16. Of course, if the number of radial lead electronic components is small due to circuit design conditions, or if the number of components to be supplied is small, it is also possible to replace the A component supply unit 14 with the R component supply unit 16 and arrange a large number of them side by side without using the sequence tape. This is clear from the relationship between the position pitches P ₁ and P ₂ based on the above-mentioned integer ratio.

Figure 4 A and B are R for radial lead electronic components.
This figure shows a schematic side view and a partial plan view of the tip of the component supply unit 16, and the R component supply unit 16 is formed as a detachable device that is fixed to the mounting base 12 with a clamp 70. It has a feed pawl 77 attached to a shaft 75 of a driven pulley 74 which is driven via a belt 73 from a drive pulley 72 which is driven to rotate intermittently by an intermittent feed mechanism 60 consisting of a well-known ratchet feed mechanism. When the ratchet wheel 76 rotates intermittently in the direction of arrow "U", the feed pawl 77 of the ratchet wheel 76 engages with the feed hole 81 of the tape 80 to which the vertically oriented radial lead electronic component 79 is fixed, and the above-mentioned As shown, the radial lead electronic components 79 are sequentially and intermittently fed to the tip of the R component supply unit 16 at the left end in the figure, and are transported from that tip position to the insertion head 40 by the transfer arm means 54 (FIG. 3). It is formed. A positioning pin 19 is attached to the pin hole 2 in the mounting base 12.

FIG. 5 is a schematic plan view of the A component supply unit 14 for axial electronic components, and this A component supply unit 14 is also mounted on the mounting base 12 by a clamp (not shown) in the same way as the R component supply unit 16 described above. It is formed as a removable device that is fixed in place. The intermittent rotation of a pulley 64 attached to one end of a transport drive shaft 63 having an intermittent feed mechanism 60 consisting of a ratchet mechanism is transmitted to a driven pulley 66 via a belt 65.

8 intermittently in a flat position. Each time the cylinder device 52 provided at the rear end of the A component supply unit 14 is operated, each axial lead electronic component 68 is inserted from the tip of the supply unit 14 directly below the insertion head 40 (FIGS. 1 and 2). It is supplied and conveyed to position A. In this case as well, the positioning pin 18 is inserted into the pin hole 20 of the mounting base 12,
As described above, the supply unit 14 is positioned in the horizontal direction of the mounting base 12.

[Effect of idea]

As is clear from the above explanation, the taping component supply device according to the present invention has an A component supply unit that supplies axial lead electronic components and an R component supply unit that supplies radial lead electronic components to the base surface of the same mounting base.
The structure is such that the parts supply units are arranged and positioned at the same time, and the number of installed parts of both supply units can be easily increased or decreased by exchanging the insertion positions of the positioning pins. Even if there is a change in the insertion conditions, that is, the electrical design conditions, and the type or number of electronic components to be inserted changes, it has the effect of being able to exhibit a wide range of functional flexibility that can immediately adapt to the change. Furthermore, the maximum number of A component supply units and R component supply units can be mounted on a mounting base of a fixed width according to the supply conditions, so that desired electronic components can be inserted efficiently.
