Japanese Patent No. 2740682

  In recent years, in order to improve the functions of an electronic component mounting apparatus, it is required that the mounting head, the orthogonal robot, and the like can be exchanged for a model corresponding to the user's usage mode and flexibly cope with customization. In particular, in response to the recent trend toward high-density mounting, there is a strong demand for replacement of a conventional orthogonal robot that uses a feed screw mechanism as a drive mechanism to an orthogonal robot that uses a linear motor mechanism as a drive mechanism. However, since the conventional electronic component mounting apparatus was not designed with a view to replacing the orthogonal robot, the driver for controlling the driving of the orthogonal robot is separate from the orthogonal robot main body. It took time to change not only the mechanical changes but also the electrical settings, and the orthogonal robot before the replacement could not be aged alone.

  Accordingly, an object of the present invention is to provide an electronic component mounting apparatus that realizes plug and play when changing the model of an orthogonal robot by making the orthogonal robot into a block kit.

And an orthogonal robot unit that moves the mounting head in a plane, wherein the orthogonal robot unit includes a first linear motion device and a second linear motion device that are orthogonal to each other. A unit that is separable from the main body of the electronic component mounting apparatus is formed. The first linear motion device includes a first guide and a first slider that slides along the guide. The second linear motion device includes a second guide and a second slider that slides along the guide, and one end of the second linear motion device is supported by the first slider, A first slider and The orthogonal robot unit is provided with an XY driver for controlling the driving of the moving means for moving the two sliders, and is stored in the main body control section and control program for controlling the operation of the electronic component mounting apparatus and the electronic component supply apparatus.

It has a function. The mounting head 7 is provided with a nozzle 9 that sucks an electronic component. The nozzle 9 sucks the electronic component supplied from the electronic component supply device 4 and mounts it on a mounting location set on the substrate 8. When mounting the electronic components, the mounting position of the substrate 8 is imaged by the imaging device 6 and the positional relationship between the nozzle 9 and the mounting position is recognized, thereby realizing an accurate alignment of both.

In FIG. 2, the orthogonal robot unit 5 includes a first linear motion device 10 in the Y direction orthogonal to each other, a second linear motion device 11 in the X direction , a support block 12, and an XY driver 13. An independent unit is formed so as to be separable from one main body. The main body refers to a portion of the elements constituting the electronic component mounting apparatus 1 excluding the orthogonal robot unit 5. The first linear motion device 10 includes a first slider 14 including a first guide 14 that extends in the Y direction and a guide block 15 that slides along the guide 14. Has a function of moving the lens in the Y direction. Similarly, the second linear motion device 11 includes a second guide 17 that includes a second guide 17 that extends in the X direction, and a guide block 18 that slides along the guide 17. The slider 19 has a function of moving in the X direction. One end of the second linear motion device 11 is supported on the first slider 16.

  As a moving means for moving the first slider 16 and the second slider 19 in the Y direction and the X direction, respectively, a feed screw mechanism or a linear motor mechanism (both not shown) are used. By controlling with the driver 13, the imaging device 6 and the mounting head 7 mounted on the second slider 19 can be positioned at arbitrary positions above the work surface 2 a and the electronic component supply device 4.

  The 1st linear motion apparatus 10 and the 2nd linear motion apparatus 11 are installed in the upper part of the support block 12 in which the lower part makes a horizontal surface. On the side of the base 2 is provided a gantry 20 whose upper part forms a horizontal plane. When the orthogonal robot unit 5 is mounted on the main body of the electronic component mounting apparatus 1, when the support block 12 is placed on the mount 20, the first linear motion device 10 and the second linear motion device 11 are moved to the work surface 2a. It is located further upward (see FIG. 1). Further, when the support block 12 is placed on the gantry 20, the XY driver 13 built in the support block 12 and the main body control unit 21 built in the base 2 are electrically connected, and the electronic component including the orthogonal robot unit 5 is connected. The main body control unit 21 is configured to control the operation of the entire mounting apparatus 1.

Next, the configuration of the control system of the electronic component mounting apparatus will be described. In FIG. 3, the main body control unit 21 is a main coat roller that controls the operation of the entire electronic component mounting apparatus 1 including the substrate transfer device 3, the electronic component supply device 4, the imaging device 6, the mounting head 7, and the orthogonal robot unit 5.

The input / output unit 23 mediates exchange of various information between the operator and the electronic component mounting apparatus 1.

The orthogonal robot unit 5 includes a relay unit 24 that is electrically connected to the main body control unit 21, and the relay unit 24 is connected to the mounting head 7, the XY driver 13, and the second storage unit 25. The second storage unit 25 identifies the model of the orthogonal robot composed of the first linear motion device 10 and the second linear motion device 11 and the model of the mounting head 7 attached to the second slider 19. ID information is stored. For example, there are many types of orthogonal robots with different moving spans and moving means, and there are many types of mounting heads 7 with different numbers and arrangements of nozzles 9, and any model is selected as the main unit. Can be installed. Since the orthogonal robot unit 5 and the main body are electrically connected only by the connector 26 interposed between the main body control unit 21 and the relay unit 24, the orthogonal robot unit 5 is attached to and detached from the main body.

  The main body control unit 21 identifies the model of the orthogonal robot and the mounting head 7 from the ID information stored in the storage unit 25 of the orthogonal robot unit 5 mounted on the main body unit, and is mounted based on the control program corresponding to the model. A control command is transmitted to each element including the head 7 and the XY driver 13, and optimal operation control of the electronic component mounting apparatus 1 is performed. A control program corresponding to each model of the orthogonal robot and the mounting head 7 is stored in the storage unit 22 in advance, and the main body control unit 21 collates the ID information stored in the storage unit 25 of the orthogonal robot unit 5. The corresponding control program is selectively used.

  Since the orthogonal robot unit 5 has a built-in XY driver 13 and is a block kit, it is connected to a controller such as a PC and energized even when separated from the main body of the electronic component mounting apparatus 1. By doing so, it can be driven. Therefore, the orthogonal robot before the model exchange can be driven and aged alone, and the mounting operation using the orthogonal robot unit 5 that has been sufficiently aged and can be used immediately can be performed. Also, the electrical settings can be changed at the time of model replacement by simply connecting the connector 26, and the ID information regarding the orthogonal robot after the replacement is automatically verified, so that the replacement work can be performed in a short time and easily. be able to.
