BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called electronic board such as a main board of a computer, a control board used for electronic control of devices ranging from electric appliances used at home to manufacturing plants in factories, and game boards for game machines. The present invention relates to a nozzle that sucks an electronic component in a mounting machine used in a line for manufacturing a board. The mounting machine has a CPU and RA on the board.
An apparatus for mounting electronic components such as M, ROM, resistors, capacitors, and various ICs. Usually, a plurality of mounting machines of different types are installed in one line, and each mounting machine has a plurality of different mounting machines. Electronic components are mounted on the board. The mounting machine has a mounting head that can move in the horizontal X-axis and Y-axis directions. The mounting head has a revolving mechanism that rotates in the horizontal direction, and a plurality of mounting heads that are held by the revolving mechanism and that vertically move the revolver unit. The lifting mechanism and a plurality of revolver units held by each lifting mechanism via a rotation mechanism, each having a plurality of nozzles, and the like. , Has the function of placing electronic components on the substrate. The present invention provides a plurality of nozzles attached to a revolver unit with a color of a predetermined hue to facilitate identification, prevents the nozzles from being mistakenly attached to the revolver unit, and facilitates discovery when they are incorrectly attached, and The present invention relates to a nozzle that is effective in preventing mistakes in ordering and shipping.

2. Description of the Related Art Conventionally, a number is attached to each nozzle mounting position of each revolver unit so that the nozzles can be easily identified visually. Further, each nozzle has a part number for each nozzle and an outer diameter of the nozzle portion. (Hereinafter, simply referred to as "nozzle diameter.") And the like are used to employ a method in which an operator visually recognizes a character to identify it. However, if the nozzle diameter is large, you can easily judge the difference by visually observing the appearance, but if the nozzle diameter is small, you can not judge it just by visually observing the appearance, and carefully check the characters marked on the nozzle. There was a need. Therefore, it is easy to accidentally attach the nozzle at the wrong position, and if it is installed incorrectly, the machine will stop.However, it is difficult to easily find out which nozzle of which revolver unit was installed incorrectly. And it took a long time to recover to the operating state, which reduced the operating rate of the line. Also, because there are multiple types of mounting machines and the nozzle holders differ depending on the model, and the sleeve and pin sizes of the holders differ, it is not possible to install the nozzles incorrectly across different models, but multiple machines must be installed. When it is used for a long time, it becomes complicated to manage the parts of the nozzle, and there is a case where an operation mistake in installing the nozzle by mistake occurs. In order to prevent the occurrence of such a work error, there is a strong demand for a nozzle that can be easily identified visually. Also, in the method of identifying parts only by the description of the nozzle part number and nozzle diameter,
This has also been a cause of mistakes in ordering parts, mistakes in shipping parts, and wrong sorting in parts storage. Further, conventionally, a yellow fluorescent color seal has been attached to the light emitting surface of the nozzle. The image of the light reflected by shining light on the light emitting surface is taken, and the position where the reflected light is blocked by the workpiece held by the nozzle and appears black is calculated to calculate the deviation between the position and angle of the electronic component, This is because it is used to correct the mounting position and angle. However, when the yellow fluorescent color sticker is misaligned, white color of the material (alumite) appears, which may cause an error in image processing or erroneous recognition.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned drawbacks of the prior art. The object of the present invention is to apply a color of a predetermined hue to an easily visible portion of a nozzle and visually check it. It is to facilitate the identification of the nozzle. Thus, it is possible to prevent an accident in which the nozzle is attached at the wrong mounting position, prevent a dead time for stopping and recovering the line, and improve the operation rate of the line. Another object is to prevent an ordering error in a part order, a shipping error in shipping a part, a sorting error in storing a part, and the like, and to prevent a wasteful cost due to a wasteful part order or a mistake in shipping work.
Furthermore, the present invention relates to providing a nozzle that does not require sticking of a sticker with a yellow fluorescent color on the light emitting surface, a nozzle that does not cause an error in image processing or misrecognize even if the position of sticking a sticker of yellow fluorescent color is displaced. .

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on the embodiments shown in the drawings. The nozzles 3 to 8 according to the present invention are used by being attached to the revolver unit 1, and the revolver unit 1 is attached to the lifting mechanism 13 via the rotation mechanism 12. The mounting head of the mounting machine includes a revolving mechanism that horizontally swings while holding 16 sets of these mechanisms, an X-axis moving mechanism and a Y-axis moving mechanism that moves horizontally. The revolver unit 1 includes a bracket 15, a shaft 14 mounted horizontally, a block 16 and the like.
The block 16 is provided with six nozzle mounting portions, and the respective positions are clearly marked and marked. Also,
The block 16 is rotatable about the axis 14 and
The positioning is stopped every time, and the nozzle portion 3a of the nozzle 3 located at the bottom is vertically downward. An example of the nozzle will be described with reference to FIG. The nozzle 3 is composed of a nozzle portion 3a and a holder 9. The nozzle portion 3a has a cylindrical shape with a nozzle diameter G of 0.4 mm and a length H of a standard length, and the holder 9 has a sleeve 9a and a pin 9b. It has each part of the flange 9e. The light emitting surface 9c of the flange 9e is colored yellow fluorescent, and the inclined surface 9d is provided on the back side of the light emitting surface 9c. As shown by different hatching in FIG. 3, the first layer 17a has a red color and the second layer has a second color. The layer 17b is colored yellow and the third layer 17c is colored white. Another embodiment of the nozzle will be described with reference to FIG. The nozzle 8 has a nozzle portion 8a having a nozzle diameter G of φ1.3 mm, a tip having a semi-circular notch 8b having a notch 8b, and a sloped surface having a red first layer. 2 is the same as the example shown in FIG. 2 except that the second layer is green and the third layer is different from orange. Further, another embodiment of the nozzle will be described with reference to FIG. Since the nozzle 11 is mounted in a different model from the example shown in FIGS. 2 and 4, the sleeve 10 a of the holder 10 and the pin 10 are different.
The size of b is different from that of the sleeve 9a and the pin 9b. Also,
In this embodiment, the flange 10e is not provided with an inclined surface, and as shown by different hatching in FIG. 5, the outer peripheral surface 10d of the flange 10e has the first layer 18a of the yellow green color indicating the model B, and the second layer 18b of the second layer 18b. A green color indicating the nozzle diameter of the nozzle portion 7a was applied.

FIG. 6 shows an embodiment defined as a hue use standard and will be described. In this embodiment, the portion to be colored is divided into three layers, the first layer is provided with the hue representing the model, the second layer is provided with the hue representing the nozzle diameter, and the third layer is provided with the hue representing the nozzle type. did. Since I currently have five models, I decided to use red for model A, yellow-green for model B, blue-green for model C, purple for model D, and blue-violet for model E. Although there are many types of nozzle diameters, those with large nozzle diameters are not colored because they can be easily judged visually, and those with small nozzle diameters that are difficult to visually identify are given colors. The hues used are yellow, blue, magenta, and green.
Is the color. There are three types of nozzles, two types of which the length H is a standard length and a short type, and three types of melf type for adsorbing cylindrical electronic parts. The hues used are three colors, white, black and orange, respectively. FIG. 7 shows the specifications of the six types of nozzles 3 to 8 attached to the revolver unit 1 of FIG. 1 and an example in which the hue used for each of them is divided into three layers and displayed.

The reason for shortening the nozzle 4 is that the nozzle diameter φ
This is because a 0.4 mm piece may be easily broken, and is used when there is a risk of breakage. Therefore, if it is a short nozzle, the nozzle diameter is 0.4 mm, and if you are accustomed to it, if you display only the short hue, the nozzle diameter is 0.4 mm without displaying the hue of the nozzle diameter. Can understand. In addition, since the melf type nozzle cannot be used with a small nozzle diameter, and the range of nozzles that are considered to require identification is limited to φ1.3 mm, it is only necessary to indicate that it is a melf type nozzle. Then φ
It can be seen that the nozzle is 1.3 mm. Therefore,
Regarding the nozzles 4 and 8, it is only indicated that the nozzle type is short or melf type, and in FIG.
An example is shown in which the specifications of the six types of nozzles 3 to 8 attached to the revolver unit of FIG. 1 and the hues used for each are displayed in two layers in different colors. The color can be applied by painting or by applying a pre-colored sticker. In this embodiment, since the material is aluminum, white is not colored and is displayed in the color of the material. Also,
The other colors were colored by the method of coloring during the alumite treatment.

The present invention is configured as described above, and its operation will be described below. For each nozzle, the inclined surface 9d of the flange 9e and the outer peripheral surface 10 of the flange 10e, respectively.
Since the layers having different hues are applied to layers such as d, the nozzles can be easily identified. If the hue of the nozzle attached to each nozzle provided on the nozzle attachment portion of the block 16 of the revolver unit 1 is displayed, it is possible to accurately select the nozzle when attaching to the machine. Also, when ordering parts for nozzles, shipping nozzles, storing nozzles, etc., if you display only the hue without the part number, or if you display the hue along with the part number, you can easily order and ship the parts without any mistakes. can do. In the above-mentioned embodiment, 12 typical colors are selected as the hue, and the hue used for the first layer, the hue used for the second layer and the hue used for the third layer are divided so as not to overlap with each other. Therefore, it is now possible to easily identify the nozzle simply by displaying the hue. Furthermore, by customizing the display of hues from the first layer to the third layer, which have been determined in advance, it is possible to display the color of each of the model of the first layer, the nozzle diameter of the second layer, and the nozzle type of the third layer. It is possible to use 12 typical colors for display, and it is possible to easily assign the hue to be displayed when the types of machines, the types of nozzle diameters to be identified and the types of nozzles increase in the future. Becomes In the present invention, since the yellow fluorescent color is applied to the light emitting surfaces 9c and 10c of the flange of the nozzle, it is not necessary to attach a yellow fluorescent color seal to the light emitting surface. Further, even when the sticker is stuck and the sticking position is displaced, there is no error in the image processing or erroneous recognition. If the light emitting surface becomes dirty, it will affect the image processing, so it is necessary to re-attach the seal fairly frequently, but the work of re-attaching the seal is unnecessary and there is no problem even if the seal is misaligned. Became.

In the above embodiment, red, orange, yellow, yellow green, green,
Twelve kinds of hues of blue-green, blue, blue-violet, purple, red-purple, white and black were used, but these colors are typical hues that are easily distinguishable from other colors. Of course, since hues that can be easily distinguished from each other may be considered, the present embodiment is not limited to this. In the above embodiment, the color is divided into two or three color layers and each color is applied. For example, three frames are provided, 1, 2,
It is also possible to consider a method of applying color along with the display of 3, 3, A, B, C, etc., and it is not limited to the above-mentioned embodiment.

[0010]

As described above, according to the present invention, since the color is applied to the easily visible part of the nozzle, it is possible to provide the nozzle which can be easily identified visually.
Therefore, according to the present invention, it is possible to prevent an accident in which the nozzle is attached at the wrong mounting position, prevent a dead time for stopping and recovering the line, and increase the operating rate of the line. Further, according to the present invention, it is possible to prevent an error in ordering a part, an error in sending a part when shipping, a wrong sorting for storing a part, and the like, and to prevent a wasteful cost due to an unnecessary part order or an error in shipping work. I was able to. In addition, since the emission surface is made of yellow fluorescent color, it is not necessary to attach a sticker, or a nozzle that does not cause error in image processing or misrecognition even if the position where the sticker is attached is displaced I was able to reduce it.
