Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an apparatus for feeding electronic components to be inserted and fixed onto a printed circuit board in an automatic electronic component insertion machine toward an insertion head, and in particular for feeding a large number of electronic components onto a tape. The present invention relates to a taping component supply device that supplies taping components arranged in a fixed manner to an insertion head.

The conventional automatic electronic parts insertion machine inserts a large number of 'electronic parts into a printed board and converts it into a converter, household dosage 1:2H,...45
Recently, many types of machines have been provided as machines for automatic FIC production of sub-covers and their substrates for industrial electronic equipment. In such an automatic electronic component insertion machine, so-called stick components are stored in a supply stick, such as IC and 'J series, and each individual component is taken out from this stick and supplied to the insertion position by an insertion head. And, like axial lead electronic components or radial lead electronic components, they are fixedly arranged on the tape at a fixed pitch! , inserted with snow (5>, n・
The so-called taping parts to be supplied towards 'vC' are respectively supplied towards the insertion position I4 by the above-mentioned insertion head by appropriate part supply means. That is, for the former stain parts, a feed chute means is used, and for the latter taping parts, a transport means having a ratchet mechanism is often used. In the latter transport means for taped parts, during the final feeding stage from the end of the transport path, including cutting and forming of the lead wires, to the insertion head, the insertion head side performs multiple swinging movements to transport the parts. Conventionally, a configuration has been adopted in which the electronic components separated from the tape are received at the end of the path, but this has the disadvantage that the cycle time becomes long because the insertion head performs a neck-carrying operation each time. . To eliminate this drawback, the electronic components are fed below the insertion head, and the lowering movement of the insertion head cuts the lead wire.
Do the molding and then! A device was developed in which the insertion head descends to insert electronic components into a printed circuit board.

Problems to be solved However, as mentioned above, with the insertion head, there is no problem if the matchmaker head and the taping parts supply device +jj correspond directly, but if one When trying to insert an electronic component from the taping component supply, f, // P i, -'+, it will interfere with the insertion head when switching the taping component supply device,
In order to paint this (('i;r'), the vertical stroke of the 5-person head has to be large.

Solution Means and Effects The present invention solves the above-mentioned problems by solving the following problems. -Look, pudding I% [K
The taping part is equipped with a spear for transporting the taping part, which is formed by arranging and securing a large number of electronic parts to be inserted and fixed onto a tape, to one end of the transport path, and extrusion means for advancing and retracting the taping part transport mechanism. A taping component supplying device 4 is provided, which supplies Jilff primary blunt electronic components from taping components to a one-man electronic component manufacturing head. By retreating,
Is it possible to see through the interference while keeping the vertical stroke of the insertion head to a minimum, and to insert the same parts or parts with sequence tape? When inserting, high-speed insertion is possible.

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

Embodiment FIG. 1 is a partial cross-sectional view showing the main components of an automatic electronic component insertion machine equipped with taping component supply means according to the present invention. In FIG. 1, the automatic 1 parishioner part I11 person reward has a matchmaker head 10 arranged at a fixed position 1σ, and this insertion head 10 includes a lower moving push rod 12 for insertion and an electronic component storage rod. 14, Cutter, lead t'4 to cut all child parts from the tape!

are installed on the positioning table 2G, and the hole position 16 into which each electronic component is inserted is set at the above position 11A, and by the f5 Mj-+ of the positioning table 26, the position N is placed directly below the single head 10. ,! , decided, F') (%゛I
-1. The child parts are inserted by pushing them in from above. Note that the feeding of the printed A plate 24 to the positioning table 26 is carried out from a direction perpendicular to the paper surface of the drawing da1.
Further, a clinch device is provided below the positioning table 26 to support the printed circuit board 24 from below when electronic components are inserted, and to bend the lead wires of the electronic components inserted into the printed circuit board to fix the electronic components.

Now, the taping component supply device 40 according to the present invention includes a supply table 3 which is capable of traversing in a direction perpendicular to the paper plane of FIG.
A plurality of taping component supply devices 40 are arranged in parallel at 2, and a desired one of the plurality of taping component supply devices 40 stops directly facing the insertion head 10 in a direction perpendicular to the traverse direction by the traverse operation of the supply table 32. It is composed of Each taping component supply device e [40 includes a taping component transport mechanism 42 for transporting the taping component to one end near the insertion head 10 as described later, and a taping component transport mechanism ij; A pushing means 46 is provided for advancing or retreating between a standby position indicated by a solid line in the figure and an insertion position immediately below the insertion head 10 indicated by a chain line. In the illustrated example, the extrusion means 46 is formed of a fluid-operated cylinder 46a, and at this time, the left end of the fluid-operated ff1b cylinder 46a is coupled to the rear end of the taping component conveyance mechanism 42. In each taping component supply device 1140, the taping component is conveyed as a continuous strip from a supply reel (not shown), for example, and is fed into the device 40 from the rear end of the taping component supply device 40. Hiroshi: A detection means, for example, a limit switch 48, is provided to detect when the rear end of the taping component forming the above-mentioned continuous band has reached near the rear end of the taping component supply device 40, and the taping of the next reel is performed according to this detection signal. Connecting parts or other 7. The taping component supplying device 40 can be properly positioned by a traverse operation to a position where it directly faces the insertion head 10. 50
is a driving piece that gives an intermittent overload effect to the taped component transport mechanism 42, and performs a constant reciprocating motion in the left and right direction. As described above, when the taped component transport mechanism 42 advances to the insertion position by the fluid-operated cylinder 46a, the taped electronic component transported to the tip 7t2 of the transport path 42 is separated from the tape by the downward movement of the insertion head. The lead prisoner is molded into a shape suitable for insertion, and then lowered to the top surface of the printed circuit board 24, and then inserted onto the printed circuit board 24 by the action of the lower moving pusher rod 12, and the printed circuit board is removed by the operation of a clinch device (not shown). will be established. During this time, the conveyor f:=42 is original Ir! b piece 5
When the next taping supply device supplies a component, the taping component transport mechanism 42 moves backward so as not to interfere with the insertion head 10 when switching the taping supply device 40.
