Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes two insertion heads to simultaneously
The present invention relates to an electronic component insertion method for inserting individual electronic components into two printed circuit boards.

In the conventional electronic component insertion method, one
A printed circuit board was mounted on an XY table, and electronic components were sequentially inserted into the printed circuit board using one insertion head. Therefore, the insertion speed is limited by the operating speed of the insertion head and the like. In order to further increase the insertion speed, it is necessary to add an XY table, an insertion head, and a mechanism for transferring electronic components to the insertion table, which is extremely uneconomical.

In view of the above points, the present invention uses two insertion heads, but allows a mechanism for transferring electronic components and an XY table to be used in common for the two insertion heads, thereby making it simple and economical. It is an object of the present invention to provide an electronic component insertion method that increases the electronic component insertion speed by using a configuration.

Embodiments of the electronic component insertion method according to the invention will be described below with reference to the drawings.

1 to 3, the electronic component transfer device 1 includes a chain 3 between sprockets 2A to 2D.
The chain has an endless chain mechanism that runs intermittently, and pallets 4 are fixed at equal intervals on this chain. Each pallet 4 consists of a series of electronic component pieces 7 obtained by cutting a series of electronic components 6 into two pieces of electronic components.
It is intended to hold the following. Supply sections 5 are arranged at equal intervals to the pallets 4 along the straight-line traveling portion of the chain 3, that is, along the straight-line traveling portion of the pallets 4,
Connected to each supply section 5 is a string of electronic components 6 pulled out from a package 9 rotatably housing a reel wound with a string of electronic components. In this case, the package cages 9 are also arranged at the same intervals as the supply section 5, and the electronic component series 6 pulled out from the package are drawn out to the supply section 5 as they are without twisting or the like. At this time, the drawer length of the electronic component series 6 is the same for each package.

A first intermittent rotary table 11 is provided near the sprocket 2C of the electronic component transfer device 1, and a first intermittent rotary table 11 is provided with first circulation chucks 10 at equal angular intervals (30 degree intervals). Circulation chuck 2
A second intermittent rotary table 21 is provided with 0 at equal angular intervals (30 degree intervals). The first circulation chuck 10 carries one of the two electronic components 8A and 8B of the electronic component continuous piece 7, that is, the electronic component 8.
The second circulating chuck 20 holds the lead wire of the remaining one of the two electronic components 8A and 8B of the electronic component continuous cut piece 7, that is, the lead wire of the electronic component 8B. It is something. Each circulation chuck 10, 20 is connected to an intermittent rotary table 1 which can rotate 90 degrees as shown in FIGS. 4 and 5, respectively.
It is pivoted to 1 and 21. Intermittent rotary table 1
The intermittent rotation pitch of sprockets 1 and 21 is set to 30 degrees, and similarly the intermittent rotation pitch of sprocket 2C is also set to 30 degrees.

First and second printed circuit boards 12 and 22 are placed on the XY table 30, and an electronic component is inserted into each printed circuit board corresponding to these first and second printed circuit boards 12 and 22. first and second insertion heads 13, 23 are arranged.

In the above configuration, sprockets 2A to 2D
Due to the intermittent rotational movement, the pallet 4 executes an intermittent traveling motion. When the pallet 4 is in a position facing the supply section 5, a series of electronic components 6 of a predetermined type is selected and cut by the supply section 5, and the series of electronic components 6 is cut into two parts as shown in FIG.
The electronic component is transferred onto a pallet 4 as a continuous electronic component piece 7 having individual electronic components 8A and 8B. The pallet 4 holding the continuously cut pieces 7 of electronic components moves in the direction of the sprocket 2C where the circulation chucks 10 and 20 face each other. The pallet 4 has a rotation mechanism, and during this movement, it rotates the posture of the electronic component continuous cut piece 7 by 90 degrees as shown in FIG.
The pallet 4 should be perpendicular to the direction of movement of the pallet 4 so that it can be easily held. Next, the pallet 4 begins to travel in an arc shape along the sprocket 2C, and when it reaches the first position A, the electronic component 8A is moved by the first circulation chuck 10 that rises vertically as shown in FIG. The lead wire is held, and at the same time, the electronic component 8A is cut off from the continuous cut piece 7 of the electronic component by the cutter. Then, the electronic component 8A passes through positions B, C, D, E, F, and G according to the intermittent rotation of the first intermittent rotary table 11 and reaches position I, where it is rotated 90 degrees as shown in FIG. The first circulation chuck 10, which has become horizontal, is transferred to the first insertion head 13, and the first insertion head 13
As a result, the electronic component 8A is inserted into the printed circuit board 12 on the XY table 30. Note that the first intermittent rotary table 11 rotates in a state where it is lowered one step. This is the first circulation chuck 10
This is to prevent it from hitting electronic components at the same time as it rotates.

The remaining electronic component 8B of the electronic component continuous cut piece 7 is
According to the intermittent movement of pallet 4, positions B', C',
It passes through D' and reaches position E', and at this position E', the lead wire of electronic component 8B is clamped by the second circulating chuck 20 which stands up vertically as shown in Fig. 4, and at the same time, the cutter The electronic component 8B is separated from the continuous cut piece 7 of the electronic component. Then, as the electronic component 8B is intermittently rotated by the second intermittent rotary table 21, it passes through positions F', G', and H' and reaches position I', where it is rotated 90 degrees as shown in FIG. The second circulation chuck 20, which is now horizontal, is transferred to the second insertion head 23, and this second insertion head 2
3, the printed circuit board 22 on the XY table 30
The electronic component 8B is inserted. in this case,
The number of intermittent feed pitches from the first position A to the first insertion head (position I), the number of intermittent feed pitches from the first position A to the second position E', and the number of intermittent feed pitches from the second position E' to the first insertion head (position I). The sum of the number of intermittent feed pitches up to the second insertion head (position I') is set equal, and the positional relationship of the first insertion head 13 with respect to the first printed circuit board 12 and the second printed circuit board 22 Since the positional relationship of the second insertion head 23 with respect to the printed circuit board 23 is set equally, the first and second insertion heads 13 and 23 can be inserted into the same insertion position of the corresponding first and second printed circuit boards 12 and 22, respectively. Electronic components can be inserted at the same time.

On the pallet 4 that has passed the second position E', there is a continuously cut electronic component fragment 7 with only the tape portion remaining, but this is rotated 90 degrees on the pallet again and returned to its original position (as shown in Figure 2). It is returned to the original position) and further removed from the pallet 4 by the discharge plate 40.

As explained above, according to the electronic component insertion method according to the present invention, the electronic component series is cut into two electronic components, and the electronic component series cut pieces are transported on a pallet, and the electronic component series is inserted into the electronic component at the first position. One electronic component of the continuous cut pieces of parts is held by a first circulation chuck and transferred to a first insertion head, and the remaining electronic components of the continuous cut pieces of electronic parts are held at a second position. By holding the electronic components in the second circulation chuck and transferring them to the second insertion head, the electronic components are simultaneously inserted into the same insertion position of the corresponding first and second printed circuit boards in the first and second insertion heads, respectively. The insertion speed can be increased. In addition, the XY table, the electronic component transfer device, the device for controlling these, etc. can be shared by the two insertion heads, which is economical.
