As shown in FIG. 6, the lifting table 5 is controlled to move up and down along two guides 21 on the left and right sides by a lifting mechanism 32 using a screw shaft 22, and the tray 2 positioned at the tray opening 9 is temporarily moved. And a component handling member such as a suction nozzle or a chuck for picking up the component 1 stored in the tray 2 pulled out to a predetermined position. Also, a component transfer head 25 for transferring the picked-up component 1 to a predetermined position is provided.

The component transfer head 25 is used for picking up and transferring the component 1, and the Xs perpendicular to each other when viewed from a plane.
In this embodiment, the tray 2 can be pulled out in the X direction by the tray loading / unloading tool 24 in multiple stages in accordance with the storage pitch of the components 1. It can move along the guide 26 only in the Y direction orthogonal to the tray loading / unloading direction. Further, a component transfer table 27 for receiving the component 1 picked up and transferred by the component transfer head 25 and transferring the component 1 to an actual component supply position to the component mounting apparatus A is also provided. The component transport table 27 is supported by an XY table 28 so that the component transport table 27 can move in the XY2 directions orthogonal to each other when viewed from above. However, how the tray 2 is pulled out and how the components 1 accommodated in the drawn tray 2 are supplied to the component mounting apparatus A can be freely selected and designed. May be directly picked up by a component handling member 36 for picking up and mounting the component 1 on the side. In this way, there is no need for any component handling member for supplying the component 1 constituted by the component transfer head 25 and the component transport table 27 to other components. The component 1 to be supplied is not limited to the electronic component, and the target to which the component 1 is supplied is not limited to the component mounting apparatus, but may be various devices that receive components and perform various operations.

The supply of the parts 1 is controlled by raising and lowering the elevating table 5 so that the tray 2 containing the predetermined parts 1 is positioned at the position of the tray entrance 9 of the cabinet 4 and the predetermined parts 1 are stored. By pulling out the loaded tray 2 by the tray loading / unloading tool 24 through the tray loading / unloading opening 9, the stored component 1 is used for the component mounting apparatus A. Each time supply of such a component 1 is completed and a new component 1 is needed, the tray 2 that has been pulled out is stored in the magazine 3 by the tray insertion / removal tool 24, and then a tray that stores the next necessary component 1 2 is positioned and pulled out in the same manner as described above, and the next necessary part 1 is ready for use. Thereafter, this operation is repeated.

As shown in FIG. 7, the component mounting apparatus A has a plurality of components for supplying various taping components 31 to the other side of the component supplying device B in addition to the component supplying device B provided in the component supplying section. The necessary number of supply cassettes C are also provided. A transport means D for a circuit board 34 on which the component 1 is mounted is provided between the component supply device B and the component supply cassette C,
Between the component supply device B and the component supply cassette C, one component loading portion 33a is conveyed from the other component unloading portion 33b, and the circuit board 34 is mounted for component mounting at the component mounting position E on the way. Then, it is supported and positioned by a support mechanism (not shown) so that the component 1 can be mounted.

On the component conveying means D, a component supply device B

And is supported by an XY support mechanism 38 so as to be able to move in the XY2 directions orthogonal to each other when viewed from above. The mounting head 35 picks up and mounts the component 1 supplied to the predetermined position by the component transport table 27 of the component supply device B, and a component handling member 36 such as a suction nozzle or a chuck for picking up and mounting the component 1. A recognition camera 138 is provided to support and be provided by the up-and-down movement mechanism 37 and to image the component mounting position of the circuit board 34 at each time and perform image recognition. A recognition camera 39 for recognizing an image of the component 1 picked up and held by the component handling member 36 from below is provided at an appropriate position.

Thus, the component mounting apparatus A transfers the predetermined component 1 picked up and carried to the predetermined position of the circuit board 34 recognized by the recognition camera 38 to the recognition camera 39.
After mounting at a predetermined angle through angle control based on the recognition of the electronic circuit board, an electronic circuit board is manufactured.

The holding member 8 in the component supply device B is
The magazine 3 is pressed and fixed at a predetermined receiving position on the elevator 5 as shown by the solid line position in FIG. 1 and the imaginary line positions in FIGS. 2 and 3 as long as they can be released, it is preferable that these switches be performed by a touch operation and be stable at each switching position. Therefore, the present embodiment employs a structure similar to that conventionally used. To explain this, as shown in FIG. 4, a fixing pin 41 pivotally supports a portion near the tail end of the stopper 42, and a fixing pin 44 pivotally supports one end of the link 43 in opposition thereto. A free end of 43 is pivotally supported by a pin 45 in the vicinity of the tip of the operating lever 46. Further, the tip of the operation lever 46 and the tail end of the stopper 42 are connected by a pin 47. Accordingly, in conjunction with the operation between the raised posture shown by the solid line and the prone posture shown by the virtual line, the movement of the pin 45 by the arrow Q and the movement of the stopper 42 and the operation lever 46 are performed. With the movement of the connecting pin 47 shown by the arrow R, the stopper 42 is raised as shown by the solid line position to release the holding and fixing of the magazine 3, and the magazine is pressed down and pressed down by the magazine 3 as shown by the imaginary line position. Since the posture changes to the fixing posture, the operation lever 46 can be used to switch the pressing portion 8 between the pressing and fixing state and the release state.

However, even if the switching operation is performed by moving the side of the stopper 42, since the tension is generated between the operation lever 46 and the operation is not performed, the switching is not performed carelessly. The fixed state of the magazine 3 at the receiving position is stable, and the position shift and dropping of the magazine 3 can be reliably prevented. However, such a specific configuration can be variously designed.

By the way, even when the magazine 3 is received at a predetermined position on the elevating platform 5, there is a case where the presser 8 is forgotten to act on the press position and is not at the press position. If the component supply operation is performed in such a state, there is a problem of the magazine 3 dropping out, the magazine 3 being displaced, and interfering with other parts of the magazine 3 and the tray 2, and the component supply operation is not completely achieved, May be damaged or the worker may be injured.

Therefore, in this embodiment, the structure of the left door 6 in FIG. 1, the first embodiment shown in FIGS. 2 and 4, and the structure of the right door 6 in FIG. The configuration of the embodiment is further adopted. In the first embodiment, when the door 6 is closed,
When the holding member 8 is not at the holding position, for example, by the interference plate 6b attached by the base frame 6a provided on the holding member 8,
The stopper 42 and the like interfere with each other as shown in FIGS. 2 and 4 so as not to be closed. In the second embodiment, when the door 6 is closed, the interference plate 6b or the like attached by the base frame 6a provided on the door 6 interferes with the operation lever 46 of the holding member 8 when the holding member 8 is not at the holding position. By pressing it down, the presser 8 is closed while moving it to the presser position.

Thus, when the door 6 is closed without the pressing member 8 being at the pressing position, in the first embodiment, the door 6 interferes with the pressing member 8 not at the pressing position and is obstructed and closed. Since the microswitch 12 does not detect the closed state of the door 6, the component supply operation is not started. Therefore, the component supply operation is started with the presser 8 not in the holding position, and the operation is completed. It is possible to prevent the parts supply operation and the safety of the device and the operator from being impaired. In addition, the operator can know the abnormality from such a situation at an early stage and take measures to prevent the loss time from becoming long. In addition, since there is no need for a detecting means relating to the magazine 3 being pressed and fixed to the receiving position by the presser 8 and an assembling work and a wiring work therefor, the apparatus cost is reduced.

In the second embodiment, the door 6 can be closed while moving the holding member 8 not at the holding position to the holding position. This closed state is detected by the microswitch 12 and the component supply operation is started. Since the operation is started, it is possible to ensure the thoroughness of the parts supply operation and the safety of the apparatus and the operator without any special work or time for setting the presser 8 to the press position. Moreover, as in the case of the first embodiment, there is no need for a detecting means relating to the magazine 3 being pressed and fixed to the receiving position by the presser 8 and assembling work and wiring work therefor, so that the apparatus cost is reduced.

Further, as in the first and second embodiments, there is no interference part such as an interference plate 6b provided on the door 6 and no holding position located in the movement locus of opening and closing the door 6. In a configuration in which the stopper 42 and the operation lever 46 of the holding member 8 interfere with each other to prevent the door 6 from being closed, or the holding member 8 is moved to the holding position as the door 6 is closed. Since the operation as in the first and second embodiments is achieved by a simple interference portion with the holding member 8 provided on the door 6, the structure is simple and the cost can be further reduced.

However, a specific interference structure can be freely selected and designed. Further, even if the presser 8 is moved to the presser position, the magazine 3 is not at the proper presser position for some reason that the magazine 3 is not received on the elevating platform 5 to a predetermined position and is hard to move. Sometimes. Therefore, even in such a case, it is preferable that when the door 6 is closed, it interferes with the presser 8 so as to receive the above-described operation, and such a configuration is also included in the scope of the present invention. Further, if there is no guarantee that the magazine 3 is received on the elevating platform 5 even when the presser 8 is at the press position, a sensor for detecting this is provided, and a useless component when the reception is not detected. The supply operation may be prevented.

[0033]

According to the main features of the present invention, there is provided a detecting means for detecting that the magazine is pressed and fixed to the receiving position by the presser, and a simple and inexpensive apparatus which does not require assembling work and wiring work. Therefore, it is possible to prevent the parts supply operation from being started in a state where the presser is not at the holding position, and to prevent the complete parts supply operation and the safety of the device and the operator from being impaired. From such a situation, it is possible to know the abnormality at an early stage and take measures to prevent the loss time from becoming long.

According to a further feature of the present invention, there is provided a detecting means for detecting that the magazine is pressed and fixed at the receiving position by a presser, and a simple and inexpensive apparatus which does not require assembling work and wiring work. The thoroughness of the component supply operation and the safety of the apparatus and the worker can be ensured without any special work or time corresponding to the presser at the presser position.

According to a further feature of the present invention, the action as claimed in claims 1 and 2 when the door is closed is achieved by a simple interference portion of the door, so that the structure is simple and the cost is further reduced. Can be planned.
