The control unit 11 also has a function of performing imaging control and image recognition by various cameras (the component recognition camera 17 and the fixed camera 18).

The conveyor 12 is configured to carry the substrate S into and out of a predetermined mounting operation position. The conveyor 12 includes a pair of conveyor rails extending in the X direction and a positioning mechanism (not shown) for positioning the substrate S at a predetermined position. As a result, the conveyor 12 conveys the substrate S in the X direction, and fixes the substrate S to a predetermined mounting work position.

The two chip component supply units 13 are provided at both ends of the component mounting apparatus 100, respectively, immediately in front (Y1 direction side). The chip feeder 13 is provided with a tape feeder 13a arranged side by side along the X direction. Each tape feeder 13a intermittently feeds the carrier tape, and supplies the electronic parts in the carrier tape to a predetermined component supply position.

The mounting portion 14 is configured to mount the electronic component supplied from the chip component supplying portion 13 and the bare chip C of the wafer W onto the substrate S. [ Specifically, the mounting portion 14 is supported so as to be movable in the horizontal direction (XY direction) above the conveyor 12 (substrate S) by the XY moving mechanism. The mounting portion 14 has a plurality (two) of suction nozzles 14a (see Fig. 2) arranged along the X direction.

When mounting the supply part of the tape feeder 13a (see Fig. 1), the mounting part 14 is moved above the predetermined part withdrawing position of the tape feeder 13a. Then, the suction nozzle 14a is lowered to draw out the electronic component. Thereafter, the mounting portion 14 is moved so as to pass above the stationary camera 18, and the lower surface of the electronic component sucked by the suction nozzle 14a is picked up. Then, the mounting portion 14 is moved upward of the substrate S. Thereafter, the suction nozzle 14a is lowered to mount (mount) the electronic component on the substrate S. When the bare chip C is individually stored in the carrier tape and supplied from the tape feeder 13a, after the bare chip C is taken out from the tape feeder 13a, as shown in Fig. 2, And the bear chip C is mounted (mounted) on the substrate S.

On the outside of the pushing direction restricting portion 52, there is provided an operation lever of a substantially L-shaped cross section, on which an operating portion of the operator is formed.

As shown in Fig. 3, the plate 2 is configured so that the flux is spread. The plate 2 is formed to extend in the direction A parallel to the sliding direction of the squeegee 3. The concave portion 21 of the plate 2 is recessed by a predetermined depth. As a result, the flux is spread in the recess 21 at a substantially uniform height.

As shown in Fig. 3, the squeegee 3 is configured to slide so as to make the flux on the plate 2 even. Specifically, the squeegee 3 is configured to move in the A direction (A1 direction and A2 direction) while being pressed in the B direction (B2 direction) and in contact with the plate 2. [ As shown in Fig. 4, the squeegee portions 31 of the squeegee 3 are provided in pairs in A1 direction and A2 direction.

The advancing direction restricting portion 51 of the squeegee retaining portion 5 is configured to regulate the movement in the A direction parallel to the sliding direction of the squeegee 3. [ The traveling direction restricting portions 51 are provided so as to face each other in the horizontal direction orthogonal to the A direction. That is, a pair of the advancing direction restricting portions 51 are provided so as to sandwich the squeegee 3 therebetween. Further, the traveling direction restricting portion 51 is fixed to the base portion 5a. Further, the advancing direction regulating portion 51 has a slit shape in which the upward direction (B1 direction) is opened. The sliding direction restricting pin (34) of the squeegee (3) is fitted into the slit shape of the advancing direction restricting portion (51). The sliding direction restricting pin 34 is brought into contact with the advancing direction restricting portion 51 in the direction A to restrict the movement of the squeegee 3 (the sliding direction restricting pin 34) in the sliding direction. As a result, the squeegee holding portion 5 is moved in the A direction so that the squeegee 3 also moves (slides) in the A direction.

The pressing direction regulating portion 52 is configured to regulate the movement in the B direction (B1 direction) parallel to the pressing direction of the squeegee 3 with respect to the plate 2. The pressing direction restricting portions 52 are provided so as to face each other in the horizontal direction orthogonal to the A direction. That is, the pair of pressing direction restricting portions 52 are provided so as to sandwich the squeegee 3 therebetween.

The pushing direction restricting portion 52 is provided separately from the advancing direction restricting portion 51. Further, the squeegee 3 is configured to be moved in the B direction (B1 direction) and to be removed in a state in which the restriction of the pushing direction restricting portion 52 is released. The pressing direction regulating portion 52 is configured to move along the direction A (horizontal direction) with respect to the squeegee 3 to regulate the movement of the squeegee 3 in the direction B (vertical direction). Specifically, the pair of urging direction restricting portions 52 are connected to each other by a connecting portion 53. The pressing direction restricting portion 52 is rotatably supported by the rotation supporting portion 54. [ The pressing direction restricting portion 52 is configured to rotate about the rotation supporting portion 54 so that the squeegee locking portion 521 moves along the direction A to lock the squeegee 3 . Since the pair of urging direction restricting portions 52 are connected by the connecting portion 53, when one urging direction restricting portion 52 is moved along the direction A, the other urging direction restricting portion 52 Similarly, it moves along the A direction.

The squeegee locking portion 521 of the urging direction restricting portion 52 is engaged with the urging portion 35 of the squeegee 3 to regulate the movement of the squeegee 3 in the B direction and to transmit the urging force to the squeegee 3 Consists of. The tip of the squeegee locking portion 521 which engages with the pressing portion 35 is formed with an inclined portion 521a (see FIG. 6) which is inclined in the direction B along the direction A. The squeegee locking portion 521 of the urging direction restricting portion 52 is configured to rest on the pushing portion 35 so as to lock the squeegee 3 (restrict movement in the B direction).

The rotation support recess 522 of the pressing direction restricting portion 52 is formed in a notch shape so as to be supported by the rotation support portion 54. [ The pushing direction restricting portion 52 is configured such that when the squeegee 3 is unlocked (the restriction in the direction B is canceled), the pivot support concave portion 522 contacts the pivotal support portion 54. [ That is, when the locking of the squeegee 3 by the squeezing direction restricting portion 52 is released, the squeezing direction restricting portion 52 pivots about the pivotal supporting portion 54. On the other hand, when the squeegee 3 is locked (the direction B is restricted), the rotation support recess 522 is configured to be separated from the rotation support portion 54 in the B direction (B1 direction).

The plunger engaging holes 523 and 524 of the urging direction restricting portion 52 are configured to engage with the plunger portion 55 to restrain movement (rotation) along the direction A of the urging direction restricting portion 52.

The plunger portion 55 is engaged with the plunger engaging hole 524 so that the urging force of the plunger 55 in the urging direction of the squeegee 3 in the direction A Thereby restricting the movement of the direction.

Here, in the first embodiment, two cut-off pins 525 are provided on one of the pair of pushing direction restricting portions 52. [ The blocking pin 525 is disposed on the upper side (B1 direction side) of the connecting portion 53 at a predetermined interval. The blocking pin 525 is configured to switch the arrival of light (visible light or infrared light) from the transparent portion 8a to the light receiving portion 8b. Specifically, the blocking pin 525 is configured to pass or block light (visible light or infrared light) from the transparent portion 8a to the light receiving portion 8b. That is, the blocking pin 525 is in a restricted state in which the movement of the squeegee 3 by the urging direction restricting portion 52 is restricted and in the restriction state in which the restriction of the movement of the squeegee 3 by the urging direction restricting portion 52 is released And to switch the arrival of the light from the transparent portion 8a to the light receiving portion 8b in accordance with the released state.

Specifically, when the restriction state of the compression direction regulating portion 52 and the release state are switched, the blocking pin 525 is configured to switch the arrival of the light from the light transmitting portion 8a to the light receiving portion 8b. That is, in the release state, when the pushing direction restricting portion 52 is in contact with the pivotal supporting portion 54 as well as in the regulating state, the pushing direction restricting portion 52 moves away from the pivotal supporting portion 54, 525 are moved.

6, when the squeegee 3 is locked by the pressing direction restricting portion 52 (movement in the B direction is restricted), light from the transparent portion 8a passes through the blocking pin 525 and / Passes through the gap of the connecting portion 53 and reaches the light receiving portion 8b. 7, when the locking by the restricting direction restricting portion 52 of the squeegee 3 is released (restriction on the movement in the B direction is released), the light from the transparent portion 8a is blocked by the blocking pin 8a, Is blocked by the light receiving portion 525 and does not reach the light receiving portion 8b. That is, the light in the transparent portion 8a can not pass through the gap between the blocking pin 525 and the connecting portion 53 by rotating the pressing direction restricting portion 52. 8, when the squeegee 3 is not provided, the light from the transparent portion 8a is blocked by the blocking pin 525 and does not reach the light receiving portion 8b. That is to say, the pivoting support recess 522 of the pushing direction restricting portion 52 is arranged so as to be in contact with the pivot support portion 54 so that the light of the light projecting portion 8a passes through the gap between the interrupting pin 525 and the connecting portion 53 I can not do it.

The air cylinder 56 is connected to the urging direction restricting portion 52 and is configured to generate a pressing force against the plate 2 of the squeegee 3. Specifically, the air cylinder 56 is configured to bias the connecting portion 53 connecting the pressing direction restricting portion 52 in the pressing direction (direction B2). The air cylinder 56 is driven by the air pressure generated by the air pressure generating portion 561 to generate a pressing force of the squeegee 3. The air pressure generated by the air pressure generating portion 561 is adjusted to a desired pressure through the regulator 562. [ That is, by operating the regulator 562, the pressing force of the squeegee 3 against the plate 2 is adjusted. For example, the pressing force is adjusted based on the viscosity information of the flux to be applied.

The flux discharging portion 6 is configured to supply the flux onto the plate 2. [ Specifically, the flux discharging portion 6 is configured to supply flux into the frame formed by the squeegee portion 31 and the wall portion 32 of the squeegee 3. [

The sensor 7 is configured to measure the amount of flux in the frame of the squeegee 3. The sensor 7 includes, for example, an ultrasonic sensor.

In the first embodiment, the squeegee detecting section 8 is configured to detect the presence or absence of the squeegee 3 installed. More specifically, the squeegee detecting section 8 is configured to detect that the squeegee 3 is provided and the movement of the squeegee 3 is restricted (locked) by the urging direction restricting section 52. That is, as shown in Fig. 6, when the squeegee 3 is locked by the pressing direction restricting portion 52 (movement in the B direction is restricted), light of the light projecting portion 8a is reflected by the light receiving portion 8b Is detected. As a result, a state in which the squeegee 3 is locked by the squeegee holding portion 5 is detected. When the squeegee 3 is locked (restricted in the direction B), a pressing force by the air cylinder 56 is generated. In other words, in the locked state based on the detection result of the light receiving unit 8b, the air cylinder 56 is driven to generate a pressing force. Further, when the regulation of the squeegee 3 in the B direction is released (the locking is released), the pressing force by the air cylinder 56 is not generated. In addition, when the squeegee detecting section 8 does not detect that the squeegee 3 is installed, the flux is not replenished (supplied) from the flux discharging section 6.

When the light of the light-projecting portion 8a is not detected by the light-receiving portion 8b based on the detection result of the light-receiving portion 8b, that is, when the squeegee 3 is not installed or is not locked The motor 41 may not be driven and stopped even when the component mounting apparatus 100 is at a timing to move the squeegee 3 in the A direction by driving the motor 41 during automatic operation. Or when light is not detected by the light-receiving unit 8b when the automatic operation of the component mounting apparatus 100 is stopped, a switch for starting automatic operation of the component mounting apparatus 100 The automatic operation may not be started even if an operation such as pressing is performed. In the case where the light of the light-projecting portion 8a is not detected by the light-receiving portion 8b, a warning display indicating that the light-emitting portion 8a is in an abnormal condition may be displayed on a monitor (not shown).

(Effects of First Embodiment)

In the first embodiment, the following effects can be obtained.

Further, the traveling direction restricting portion 231 has a slit shape in which the upward direction (B1 direction) is opened. The sliding direction restricting pin 234 of the squeegee 220 is fitted into the slit shape of the advancing direction restricting portion 231. The sliding direction restricting pin 224 is brought into contact with the advancing direction restricting portion 231 in the direction A to restrict the movement of the squeegee 220 (the sliding direction restricting pin 224) in the sliding direction.

The pressing direction restricting portion 232 is configured to restrict movement of the squeegee 220 in the direction B (the direction B1) parallel to the direction in which the squeegee 220 is pressed against the plate 210. [ A pair of the pushing direction restricting portions 232 are provided so as to face the horizontal direction perpendicular to the direction A. That is, the pair of pressing direction restricting portions 232 are provided so as to sandwich the squeegee 220 therebetween.

The pushing direction restricting portion 232 is provided separately from the advancing direction restricting portion 231. [ Further, the squeegee 220 is configured to be moved in the B direction (B1 direction) and to be removed in a state in which the restriction of the pressing direction restricting portion 232 is released. The pressing direction restricting portion 232 is configured to move parallel to the squeegee 220 in the A direction (horizontal direction) to restrict the movement of the squeegee 220 in the B1 direction (upward direction).

The tip portion of the pressing direction restricting portion 232, which engages with the pressing portion 225, is formed with an inclined portion 232a whose size in the direction B is changed along the direction A to be inclined.

The contact portion 234 is configured to switch the arrival of light (visible light or infrared light) from the light transmitting portion 241a to the light receiving portion 241b. Specifically, the contact portion 234 is configured to pass or block light (visible light or infrared light) from the transparent portion 241a to the light receiving portion 241b. That is, the contact portion 234 is released from the restricted state in which the movement of the squeegee 220 by the urging direction restricting portion 232 is restricted and the restriction of the movement of the squeegee 220 by the urging direction restricting portion 232 And the arrival of the light from the transparent portion 241a to the light receiving portion 241b is switched in accordance with the released state.

As a result, a state in which the squeegee 220 is locked by the squeegee holding portion 230 is detected. On the other hand, as shown in Fig. 12, when the squeegee 220 is not locked by the urging direction restricting portion 232 (regulation of movement in the B direction is released), the light of the transparent portion 241a is transmitted to the light- 241b. That is, the light from the transparent portion 241a is blocked by the contact portion 234 and does not reach the light receiving portion 241b because the holding portion 230b (contact portion 234) contacts the base 230a.

Further, in the second embodiment, the squeegee detecting section 241 is configured to detect the presence or absence of the squeegee 220 installed. More specifically, the squeegee detecting unit 241 is configured to detect that the squeegee 220 is provided and the movement of the squeegee 220 is restricted (locked) by the urging direction restricting unit 232.

More specifically, when the squeegee 220 is provided as shown in Fig. 9, the light of the light transmitting portion 242a is not detected by the light receiving portion 242b. That is, the light from the transparent portion 242a is blocked by the squeegee 220 and does not reach the light-receiving portion 242b. On the other hand, when the squeegee 220 is not provided, the light of the light projecting unit 242a is detected by the light receiving unit 242b. That is, the light from the transparent portion 242a reaches the light receiving portion 242b without being blocked.

When the squeegee detecting section 242 does not detect the installation of the squeegee 220 or the light of the light projecting section 242a is not detected by the light receiving section 242b based on the detection result of the light receiving section 242b , The component mounting apparatus 100 may be stopped without moving even when the squeegee 3 is relatively moved in the A direction by the movement of the plate 210 during the automatic operation. Alternatively, if the above-described detection state occurs when the automatic operation of the component mounting apparatus 100 is stopped, automatic operation is started even if an operation such as pressing down of a switch for starting automatic operation of the component mounting apparatus 100 is started . Further, in the case of the detection state, a warning display indicating that the monitor is in an abnormal state may be displayed on a monitor (not shown).
