Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a component mounting machine equipped with a component mounting head to which a plurality of types of suction nozzles can be attached and detached. This invention relates to a light reflecting device.

Conventional technology In electronic component mounting machines that mount electronic components of various sizes onto printed circuit boards, multiple types of suction nozzles are removably installed on the component mounting head. Small-diameter suction nozzles are used for each part.

In addition, in order to recognize the shape and suction posture of the electronic component held by the suction nozzle, as shown in FIGS. 6 and 7,
A component recognition means b for recognizing the electronic component a and a component illumination means C for illuminating the electronic component a are provided in the component recognition station. The suction nozzle d is provided with a fixed reflection part e that reflects the illumination light toward the electronic component a,
For recognition of large parts shown in Fig. 7, the suction nozzle d
A shutter-type reflecting member ``,r'' is provided at the component recognition station, which is openable and closable so as to sandwich the electronic component a from both sides, and reflects the illumination light toward the electronic component a in the closed state.

Conventionally, in the case of a component mounting head having multiple nozzle attachment parts, there is a attachment part for small parts to which a suction nozzle d equipped with a fixed reflection part e is attached, and a part for large parts to which a suction nozzle d not equipped with this is attached. The attachment part is set in advance, and when the suction nozzle d attached to the attachment part for small parts is used, the shutter-type reflective member ``is kept open and the fixed reflection part e of the suction nozzle d is used to collect electronics. The electronic component a is illuminated using a shutter-type reflective member f when the suction nozzle d attached to the large component mounting section is used.

Problems to be Solved by the Invention However, in the above conventional example, when a suction nozzle for small parts is attached to a mounting part for large parts, or a suction nozzle for large parts is attached to a mounting part for small parts, the shutter second reflection member is Since the suction nozzle cannot operate according to the electronic component to be suctioned and held, the selection range of suction nozzles that can be attached to the component mounting head is narrow, and it is difficult to select and install an appropriate suction nozzle depending on the production model. There is a problem.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a component mounting machine that can expand the selection range of suction nozzles that can be attached to the nozzle for component mounting.

Means for Solving the Problems In order to achieve the above object, the present invention provides a component mounting head to which a plurality of types of suction nozzles can be attached and detached, a component recognition means for recognizing a component suctioned and held by the suction nozzle, and a component mounting head capable of attaching and detaching a plurality of types of suction nozzles; A component illumination means for illuminating the suction nozzle, a shutter-type reflecting member that is openable and closable so as to sandwich the suction nozzle from both sides and reflects the illumination light in the closed state, and a fixed reflection part that reflects the illumination light are suctioned. a detection means for detecting whether or not the nozzle is equipped with the shutter-type reflecting member, and when the fixed reflecting member is detected, the shutter-type reflecting member is held in an open state when recognizing a component to be held by the suction nozzle; The present invention is characterized in that the shutter-type reflecting member is configured to be in a closed state when the fixed reflecting member is not detected and the component held by the suction nozzle is recognized.

Effects According to the above configuration, it is detected for each component mounting head whether or not the suction nozzle to be used is equipped with a fixed reflector, and if the fixed reflector is not detected, the shutter-type reflector is used to illuminate the component. When the fixed reflecting member is detected, the shutter-type reflecting member remains open and the fixed reflecting member can be used to illuminate the component.

In this way, the opening/closing operation of the shutter type reflection member can be controlled according to the suction nozzle attached to the component placement head, so any suction nozzle can be attached to the component placement head, and the suction nozzle to be used can be selected. The range can be expanded.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 5.

As shown in FIG. 1, the component mounting machine of this embodiment includes a component supply section 2 that supplies electronic components (components) to be mounted, and an X-Y table 4 on which a print board IIi 3 is placed. In between, ten component mounting heads 5 arranged in an annular shape are provided, and these component mounting heads 5 are configured to be intermittently moved clockwise relative to ten stations S, to S10. Each component mounting head 5 has five nozzle mounting portions, and by rotating the component mounting head 5 about its vertical axis, the suction nozzles 6 can be switched between uses. These suction nozzles 6 can be roughly divided into types, as shown in FIGS. 2 and 3.
There are two types: one for small parts that is equipped with a fixed reflector 7, and the other for large parts that does not have the fixed reflector 7, as shown in FIGS. 4 and 5.

The first station S1 is a component take-out station, where the suction nozzles 6 of each component mounting head 5 suck and take out a predetermined electronic component l from the component supply section 2. At the second station S2, the suction nozzle 6 is rotated by θ around its axis.

The third station S3 includes a component recognition stage 8 for recognizing the shape and suction posture of the electronic component 1 held by the suction nozzle 6, a component illumination means 9 for illuminating the electronic component 1, and left and right components. 1 pair of reflective plates (shutter type reflective member) 1
A shutter-type reflection device 11 for opening and closing operations of 0 and 10 is provided. The illumination light from the component illumination stage 8 is reflected by the reflecting plate 10 or the fixed reflecting plate 7 toward the electronic component 1, and its silhouette image is recognized by the component recognition means 8. The fourth station S4 is an empty station.

At the fifth station S, θ correction of the electronic component 1 is performed. At the sixth station S6, the electronic component 1 is mounted on the printed circuit board 2. The seventh station S7 is an empty station. At the eighth station S8, the electronic component l that was not installed because it is a defective product is discharged. The ninth station S is a nozzle switching station where the suction nozzle 6 to be used is changed for each component mounting head 5 according to the size of the electronic component 1 to be suctioned and held next.

The 10th station SIO is a fixed reflection plate detection station, and is provided with a detection means 12 for detecting the presence or absence of the fixed reflection Fi7 of the switched suction nozzle 6. This detection means 12 is connected to the shutter type reflection device l1, and when the fixed reflection plate 7 is detected, when the component mounting head 5 reaches the third station S3, the operation of the shutter type reflection device 11 is temporarily stopped. Stop. Therefore, in this case,
As shown in FIG. 3, the reflection plate 10 of the shutter-type reflection device 11 is held in an open state, and the illumination light from the component illumination stage 8 is reflected by the fixed reflection plate 7 toward the electronic component l.

If the fixed reflector 7 is not detected, the shutter-type reflector 1l is activated, and as shown in FIG. These reflecting plates 10 reflect the illumination light toward the electronic component l.

According to this embodiment, depending on whether the suction nozzle 6 to be used is equipped with the fixed reflection plate 7,
Since the operation of the component mounting head 5 can be controlled,
Any suction nozzle 6 can be attached to each suction nozzle attachment part. Therefore, the selection range of usable suction nozzles 6 can be expanded, and an appropriate suction nozzle 6 can be used depending on the production model.

The present invention can be configured in various ways other than those shown in the above embodiments. For example, the component mounting head may be of a type other than an intermittent rotation type. Further, in the above embodiment, the detection means of the fixed reflection portion is provided at a station between the nozzle switching station and the component take-out station, but it may also be provided, for example, at the component recognition station.

Effects of the Invention Since the present invention has the above-described structure and operation, any suction nozzle can be attached to the component mounting head regardless of whether or not there is a fixed reflection part, and the range of suction nozzles to be used can be expanded.

As a result, it is possible to easily perform component mounting work according to the production model using an appropriate suction nozzle.
