7 is a guide for moving the component cassette 1, 8 is a stopper having a mouth/socket 8a, 12 is a table, and 13 is an electronic component mounted on the board 5. , 40 is a convex portion provided at the bottom of the component cassette 1, 41 is a table that supports the component cassette 1, 42 is a recess formed in the table 41, 43
is a hook provided on part 1 set 1, and by moving the stopper 8 in the direction shown by arrow I, the rod 8
a pushes down the corner 43 and places the parts cassette 1 on the table 4.
Fixed to 1.

A plurality of component cassettes 1 are arranged on a table 41, and by moving the table 41, a plurality of types of electronic components can be moved under the transfer head 4, and various electronic components can be mounted. It is composed of

The operation of the conventional electronic component mounting apparatus configured as described above will be described below.

First, the table 41 is moved along the guide 7, and the component cassette 1 containing electronic components to be mounted under the transfer head 4 is moved. Next, the nozzle 4a sucks up the electronic components,
The transfer head 4 is moved in the direction shown by arrow B, and the nozzle 4a is lowered at the mounting position above the board 5 to mount the electronic component.

Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, it is necessary to lift the component cassette 1 once before replacing it, which makes it difficult to perform quick replacement and difficult to automate. In order to solve this problem, it is possible to replace the parts cassette 1 by sliding it, but in this case, since the table 41 is movable, the table 41
If an attempt was made to replace the upper component cassette, there was a problem in that the device would become complicated.

Means for Solving the Problems The present invention includes a first table having a slide groove, a second table having a plurality of slide grooves and movable in a direction perpendicular to the slide grooves, and a table that slides a component cassette. It is equipped with a moving means for moving the vehicle.

Operation With the above configuration, an empty parts cassette is slid and moved to the second table, and a new parts cassette is slid and moved to the first table.

Embodiment An electronic component mounting apparatus according to an embodiment of the present invention will be described below.

FIG. 1 is a sectional view of the main parts of the electronic component mounting apparatus of this embodiment, in which 1 is a component cassette, 2 is a tape, 4 is a transfer head,
5 is a board, 6 is a guide rail, 7 is a guide, 12 is a table, and 13 is an electronic component, which are the same as in the conventional example. 3 is a table that holds the component cassette 1 and has a stopper 3a for the component cassette 1; 9 is a corner provided under the component cassette 1; and 10 is provided below the stopper 3a to connect the corner 9 with the table 3. The temporary spring 11 inserted between them is a slide block provided at the bottom of the component cassette 1. The component cassette 1 slides on the table 3 by the corner 9 and the slide block 11, and the plate spring 10
The slide block 1 is pressed against the table 3 by
The position is determined by the positioning hole 34 provided in 1. 14 is a component mounting unit, 15 is a component stock unit, 16 is a guide rail of the component cassette 1, 17 is a groove formed on the side surface of the guide rail 16, 19 is a C-shaped member,
Reference numeral 20 denotes a T-shaped member provided at the rear of the set of parts 1 and held by one C-shaped member, and is configured so as not to prevent the table 3 from moving as shown in FIG. 21 is a ball screw for moving the table 3;
2 is a bracket, 23 is a cylinder that operates the bracket 22, 24 is a guide, 25 is a ball screw, 27 is a frame, 28 is attached to the frame 27, and the rod 2
8a, one C-shaped member is attached to the tip of the rod 28a, and the C-shaped member 1
The component cassette 1 is moved in the direction shown by the arrow F by pulling the rod 28a with the T-shaped member 20 biting the part cassette 9. 30 is a table that is supported by the kite 24 and moved by a ball screw 25 and holds the component cassette 1; 31 is a groove formed on the table 30; 32 is a table that supports the table 30; 33 is held inside the table 3. The spring 35 is a positioning pin that protrudes by being pushed by the spring 33 and enters the positioning hole 34. One end of the positioning pin 35 has a collar 35a.
is formed, and when the cylinder 2:3 pulls the bracket 22 in the direction shown by arrow G, the positioning pin 35 is pulled in the direction shown by arrow G, and the positioning pin 35 is removed from the positioning hole 34, and the part is removed. Cassette 1 becomes movable. 36 is a detector that detects the presence or absence of electronic components.

FIG. 2 is a perspective view of the main parts of the electronic component mounting apparatus of this embodiment, in which 18 is a rib that fits into the groove 17 and prevents the component cassette 1 from falling; 26 is a motor that rotates the ball screw 25; Electronic component supply section 37 is a ball screw 21
It is a motor that rotates.

The operation of the electronic component mounting apparatus of this embodiment configured as described above will be described below.

As in the conventional example, component cassettes 1 each holding a plurality of types of electronic components are placed on the table 3, and each component cassette 1 is positioned by a plate spring 10 and a positioning pin 35. The table 3 is moved in the direction indicated by the arrow or the opposite direction, and the component cassette 1 holding the electronic components to be mounted is moved below the transfer head 4. Next, the nozzle 4a descends, picks up the electronic component at the supply position 29, and moves in the direction shown by arrow B with the nozzle 4a raised. When the nozzle 4a reaches the mounting position on the board 5, the nozzle 4a descends and the electronic component is mounted on the board 5.

Next, a case will be described in which the electronic components in the component cassette 1 run out while the electronic components are being supplied.

When the detector 36 detects that the electronic component in the component cassette 1 is missing, the cylinder 23 first pulls the bracket 22 in the direction shown by arrow G, lowers the positioning pin 35, and removes the positioning pin 35. Hole 3 for positioning
4 to 9L L, make the component cassette 1 slidable. Next, the cylinder 28 pulls the rod 28a in the direction indicated by arrow F, and the component cassette 1 is moved onto the table 30. At this time, the component cassette 1 is guided by the guide rail 1G and the groove 31 of the table 3 and moves.

Next, the table 30 is moved in the direction indicated by the arrow E, the new component cassette 1 is moved in front of the rod 28a, the rod 28a is moved in the opposite direction to the direction indicated by the arrow F, and the component cassette 1 is placed on the table 3. , move the bracket 22 in the opposite direction of arrow G, insert the positioning pin 35 into the positioning hole 34, and position it.
Resume the mounting operation.

Note that the component cassette 1 is prevented from falling and coming off on the table 3 by the groove 17 and the rib 18;
0, the component cassette 1 on the table 30 can be easily replaced because it only rests on the groove 31.

Effects of the Invention The present invention includes a first table having a slide groove, a second table having a plurality of slide grooves and movable in a direction perpendicular to the plane, and a component cassette to be moved by sliding. The empty parts cassette is slid to the second table, and a new part cassette is slid to the first table. Parts cassettes can be quickly replaced.
