Description

  The present invention relates to a mounting head that sucks a component with a suction nozzle and a component mounting apparatus including the mounting head.

  The component mounting apparatus is a device that mounts a component on a substrate positioned by a substrate transport unit that transports a substrate, and includes a mounting head that sucks a component supplied by a component supply unit. The mounting head has a suction nozzle at the lower end of a movable shaft that can be moved up and down with respect to the fixed shaft. By supplying a vacuum pressure to the suction nozzle, the suction nozzle can suck the components. The vacuum pressure is introduced into the suction nozzle through the air tube to which the vacuum pressure is supplied and the vacuum pressure that is attached to the movable shaft and introduced from the air tube into the internal pipe of the movable shaft. The air tube is attached in a state where a certain angle is maintained with respect to the vacuum pressure introducing portion. (For example, patent document 1).

  As described above, when the vacuum pressure introduction part moves up and down together with the movable side shaft, and the air tube is attached in a state maintaining a certain angle with respect to the vacuum pressure introduction part, the air is moved by the movement of the movable side shaft. Unreasonable deformation was given to the tube, and the air tube could fall off from the vacuum pressure introduction part or be damaged. For this reason, conventionally, the length of the air tube is made sufficiently long so that the bending state of the air tube changes in conjunction with the lifting and lowering movement of the movable shaft so that the tube is not deformed excessively. ing.

  However, if the air tube is long, the entire air tube vibrates with the movement of the mounting head, which is transmitted to the suction nozzle, which may deteriorate the mounting accuracy. Further, the air tube may interfere with the suction nozzle, and the air tube may be damaged.

  Accordingly, the present invention provides a mounting head and a component mounting apparatus that can prevent a decrease in mounting accuracy caused by a long air tube and damage of the air tube caused by the air tube interfering with a suction nozzle. With the goal.

  The mounting head according to claim 1 is provided in a component mounting apparatus, and supplies a vacuum pressure to a suction nozzle attached to a lower end of a movable shaft that is movable up and down with respect to a fixed shaft, so that the component is placed on the suction nozzle. A mounting head for adsorption, an air tube to which a vacuum pressure is supplied, and a vacuum pressure introduction that is provided on the movable side shaft and introduces the vacuum pressure supplied from the air tube into the internal pipe of the movable side shaft The vacuum pressure introducing portion includes a base portion attached to the movable side shaft, and a connection portion that is provided on the base portion so as to be rotatable in the upper and lower surfaces and is connected to the air tube.

  According to a second aspect of the present invention, there is provided a component mounting apparatus, comprising: a substrate conveyance unit that conveys and positions a substrate; a component supply unit that supplies a component; and a component that is movable with respect to the substrate. The mounting head according to claim 1, wherein the component is mounted on the substrate positioned by the substrate transport unit by vacuum suction.

  In the present invention, of the vacuum pressure introduction part that introduces the vacuum pressure supplied from the air tube into the inner pipe line of the movable shaft, the connection part to which the air tube is connected is rotatable within the upper and lower surfaces. When the air tube is deformed in response to the lifting and lowering operation of the movable side shaft with respect to the fixed side shaft, the connecting portion rotates following this, so that the air tube is not excessively deformed. For this reason, unlike the conventional case, there is no need to take measures such as lengthening the air tube in order to change the bending state of the air tube in accordance with the up-and-down movement of the movable shaft. Therefore, it is possible to prevent the mounting accuracy from being lowered due to the long air tube and damage to the air tube caused by the air tube interfering with the suction nozzle.

  7A, 7 </ b> B, and 8 </ b> B, the connection member 53 is provided with a tube lower end connection portion 54 to which the lower end of the air tube 28 is connected. The space formed with the above-mentioned two connecting member inner seal members 53b, the inner peripheral surface of the through hole 53a of the connecting member 53 and the outer peripheral surface of the shaft member 52 is a circular groove (connecting member inner peripheral groove 53c). The connecting member inner circumferential groove 53c communicates with an air conduit 54a extending through the tube lower end connecting portion 54 in the axial direction thereof. As described above, in the present embodiment, the vacuum pressure introducing portion 29 is provided with a base (block member 51 and shaft member 52) attached to the movable shaft, and is provided on the base so as to be rotatable within the upper and lower surfaces. It is comprised from the connection part (connection member 53) connected with the tube 28. FIG.

  In FIG. 7B, an axial passage 52c formed in the axial direction (X-axis direction) is provided in the shaft member 52, and crosses the axial passage 52c in the central body portion 52a. A central body through passage 52d (see also FIG. 8 (b)) extending in the radial direction of the shaft member 52 and an axial passage 52c in the end body 52b and extending in the radial direction. Further, an end body through-hole 52e (see also FIG. 8B) is provided. Both ends of the central trunk portion through passage 52d are opened in the connecting member inner circumferential groove 53c, and the end trunk portion through passage 52e extends in the block member 51 in the Y-axis direction. 51c (FIGS. 7A and 7B).

  In FIG. 7A, a shaft insertion hole 51d through which the rotating portion 23b of the movable side shaft 23 is inserted extends through the block member 51 in the vertical direction, and a ring is provided at the intermediate portion of the shaft insertion hole 51d. Two sealing members (in-block member sealing member 51e) are vertically arranged. The rotating portion 23b of the movable side shaft 23 is vertically supported by the two block member inner seal members 51e while vertically passing through the shaft insertion hole 51d of the block member 51. The space surrounded by the two inner seal members 51e, the inner peripheral surface of the shaft insertion hole 51d, and the outer peripheral surface of the rotating portion 23b of the movable shaft 23 is a circular groove (block member inner peripheral groove 51f). The block member inner passage 51c communicates with the block member inner circumferential groove 51f (FIG. 7B).

  7 (a) and 7 (b), the rotating portion 23b of the movable shaft 23 is provided with a shaft communication passage 23d penetrating in the radial direction through the inner shaft passage 23c as the inner passage. The shaft communication path 23d opens into the block member inner circumferential groove 51f described above. For this reason, the air tube 28 attached to the tube lower end connecting portion 54 of the connecting member 53 includes an air conduit 54a, a connecting member inner circumferential groove 53c, a central trunk passage 52d, an axial passage 52c, and an end trunk passage. 52e, the block member inner passage 51c, the block member inner circumferential groove 51f, and the shaft communication passage 23d are connected to the shaft inner passage 23c. Since the in-shaft conduit 23c is connected to the inner conduit (not shown) of the suction nozzle 16a attached to the lower end of the rotating portion 23b of the movable shaft 23, the vacuum pressure from the aforementioned vacuum source (not shown) is The vacuum pressure supply pipe 27, the joint part 26, the air tube 28, and the vacuum pressure introduction part 29 are supplied to the suction nozzle 16a through the in-shaft pipe line 23c.

  As described above, since the central body through-hole 52 d provided in the shaft member 52 communicates with the circumferential connection member inner circumferential groove 53 c, the connection member 53 rotates with respect to the shaft member 52. Even in this case, the communication state between the connecting member inner circumferential groove 53c and the axial passage 52c is maintained. Similarly, the shaft communication path 23d provided in the rotating portion 23b of the movable side shaft 23 communicates with the circular block member inner peripheral groove 51f, so that the rotating portion 23b of the movable side shaft 23 becomes the non-rotating portion 23a. Even if it rotates with respect to (that is, with respect to the block member 51 fixed to the non-rotating part 23a), the communication state of the block member inner circumferential groove 51f and the shaft inner pipe line 23c is maintained.

  As shown in FIG. 3, an adsorption control mechanism 61 including a vacuum pressure supply control valve or the like is provided at a position adjacent to the joint portion 26. The suction control mechanism 61 can be operated through a signal line 62, whereby the supply control of the positive pressure to the suction nozzle 16a as well as the supply control of the vacuum pressure to the suction nozzle 16a can be performed.

  In FIG. 9, substrate 2 transport and positioning operation control by the substrate transport unit 12 (transport conveyor 12 a), component 3 supply operation control by the component supply unit 13 (part feeder 13 a), and movement of the mounting head 16 by the head moving mechanism 15. Operation control, elevating operation control of each movable side shaft 23 by the elevating motor 24, rotation operation control around the Z axis of the rotating portion 23b of each movable side shaft 23 by the rotation driving unit 25, and each adsorption nozzle 16a by the adsorption control mechanism 61 The supply control of the vacuum pressure (or positive pressure) is performed by the control device 70 provided in the component mounting apparatus 1. Further, the imaging operation control by the substrate camera 17 and the imaging operation control by the component camera 18 are performed by the control device 70, and the image data obtained by the imaging operation of the substrate camera 17 and the image data obtained by the imaging operation of the component camera 18 are The image is sent to the control device 70 and image recognition is performed in an image recognition unit 70 a included in the control device 70.

  Next, a procedure for mounting the component 3 on the board 2 executed by the control device 70 will be described. The control device 70 first transports the substrate 2 sent from another device on the upstream side of the component mounting device 1 by the substrate transport unit 12 and positions it at a predetermined work position (FIG. 1). Then, the mounting head 16 is moved in the horizontal plane by the head moving mechanism 15, the substrate camera 17 is positioned above the substrate 2, and a position recognition mark (not shown) provided on the substrate 2 is imaged. Then, an image of the obtained position recognition mark is image-recognized by the image recognition unit 70a, thereby detecting a displacement of the substrate 2 from the normal work position.

  When the control device 70 detects the displacement of the substrate 2, the control device 70 controls the operation of the head moving mechanism 15 to move the mounting head 16 above the component supply unit 13 and performs the operation of supplying the component 3 to each part feeder 13 a. In addition, the elevator motor 24, the rotation drive unit 25, and the suction control mechanism 61 are controlled so that the component 3 is sucked and picked up by the suction nozzle 16a. Then, the mounting head 16 is moved so that the component 3 picked up by the suction nozzle 16a passes above the component camera 18, and imaging of the component 3 by the component camera 18 and image recognition of the image data obtained thereby are performed. Then, the positional deviation (suction deviation) of the component 3 with respect to the suction nozzle 16a is obtained.

  When the controller 70 determines the positional deviation of the component 3 relative to the suction nozzle 16a, the controller 70 moves the mounting head 16 so that the component 3 is positioned above the substrate 2. Then, the suction nozzle 16a is lowered and the component 3 is mounted on the substrate 2 (FIG. 10 (a) → FIG. 10 (b) → FIG. 10 (c)). When the component 3 is mounted, the control device 70 performs position correction (including rotation correction) of the suction nozzle 16a with respect to the substrate 2 so that the already-determined positional displacement of the substrate 2 and the suction displacement of the component 3 are corrected. Do. When the mounting of all the components 3 to be mounted on the board 2 is completed, the control device 70 operates the board transport unit 12 to carry the board 2 out of the component mounting apparatus 1.

  In the mounting operation of the component 3 as described above, when the component 3 sucked by the suction nozzle 16a is mounted on the substrate 2, the movable shaft 23 is lifted and lowered with respect to the fixed shaft 22, but the movable shaft 23 is When it is lowered from the initial position shown in FIG. 10A, the vacuum pressure introducing portion 29 attached to the movable shaft 23 is also lowered integrally (FIG. 10A → FIG. 10B → FIG. 10). (C)). At this time, the lower end of the air tube 28 connected to the vacuum pressure introducing portion 29 is moved downward, but the connection member 53 of the vacuum pressure introducing portion 29 to which the lower end of the air tube 28 is attached is deformed by the air tube 28. Following the rotation around the shaft member 52, that is, within the upper and lower surfaces, the air tube 28 is not deformed excessively.

  Further, while the mounting operation of the component 3 as described above is repeatedly performed, foreign matters contained in the vacuum air adhere to the filter member 33 housed in the housing member 31 of the joint portion 26. The operator OP needs to periodically remove and replace the filter member 33 from the housing member 31. When the operator OP removes the filter member 33 from the housing member 31, the operator OP presses the operation portion 35 c of the slider 35 attached to the housing member 31 to move the slider 35 from the “holding position” to the “non-holding position”. Let As a result, each claw portion 35d of the slider 35 is disengaged from the locking groove 32d of the tube connector 32 inserted into each insertion hole 31a, so that the operator OP can pull out the tube connector 32 from the insertion hole 31a. Become. Then, after removing the filter member 33 from the extracted tube connector 32, replacing it with a new one and attaching it to the tube connector 32 again, the tube connector 32 is returned to the insertion hole 31a while operating the slider 35.

  When the slider 35 is changed from the “holding position” to the “non-holding position”, the locking of the claw portions 35d with respect to the plurality of tube connecting devices 32 is simultaneously released, but each tube connecting device 32 has an O-ring as described above. Since it is fixed in the insertion hole 31a by 32e, the tube connector 32 will not fall out of the insertion hole 31a unless the operator OP intentionally pulls out the tube connector 32. For this reason, the operator OP can select only the object to be pulled out, pull out from the insertion hole 31a, and then perform operations such as replacement of the filter member 33.

  As described above, in the component mounting apparatus 1 according to the present embodiment, the vacuum pressure introduction unit 29 that introduces the vacuum pressure supplied from the air tube 28 into the internal pipe line (in-shaft pipe line 23c) of the movable shaft 23. Among them, a connecting member 53 as a connecting portion to which the air tube 28 is connected is rotatable within the upper and lower surfaces, and the air tube 28 is deformed in accordance with the raising and lowering operation of the movable side shaft 23 with respect to the fixed side shaft 22. When this happens, the connecting member 53 rotates following this, so that the air tube 28 is not deformed excessively. Therefore, unlike the prior art, there is no need to take measures such as lengthening the air tube 28 so that the bent state of the air tube 28 changes in conjunction with the up-and-down movement of the movable shaft 23. In addition, since the air tube 28 can be shortened, it is possible to prevent a reduction in mounting accuracy due to vibrations caused by the long air tube 28 and damage to the air tube 28 caused by the air tube 28 interfering with the suction nozzle 16a. can do.

  Provided are a mounting head and a component mounting apparatus capable of preventing a decrease in mounting accuracy caused by a long air tube and damage of the air tube caused by interference of the air tube with a suction nozzle.
