A mounting operation can be performed.

(Electronic component mounting operation)
In the head unit 100 having such a configuration, when the electronic component 1 is mounted at a predetermined position on the circuit board, the head unit 100 is provided above the electronic component 1 to be mounted on the circuit board. After positioning one suction nozzle 2 of the respective suction nozzles 2, the spline shaft 11 is lowered by the elevating device 20, thereby lowering the one suction nozzle 2, and lowering the lower end portion thereof. It is brought into contact with the upper surface of the electronic component 1. At the same time, an “adsorption pressure” that is a “negative pressure” that can be generated by, for example, evacuation is added to the tip portion of the adsorption nozzle 2, and the electronic component is in contact with the adsorption pressure. 1 is sucked and held by the suction nozzle 2. Thereafter, the suction nozzle 2 is raised by the elevating device 20 and the head unit 100 is moved so that the suction nozzle 2 is positioned above the mounting position of the electronic component 1 on the circuit board. After the movement, the suction nozzle 2 is lowered again by the elevating device 20, and the electronic component 1 is placed at the mounting position. Thereafter, “adsorption release pressure”, which is “positive pressure” that can be generated by, for example, compressed air, is added to the tip portion of the adsorption nozzle 2 in place of the adsorption pressure. The electronic component 1 can be mounted at the mounting position of the circuit board by releasing the suction holding of the component 1 and raising the suction nozzle 2 with it. In addition, such control of each operation | movement is performed by the control part 9 collectively, correlating each other's operation | movement.

  Here, the “adsorption pressure” is a pressure that makes the inside of the nozzle pressure guide passage 2b of the adsorption nozzle 2 “negative pressure” with respect to the outside (that is, the outside of the adsorption nozzle 2). The pressure is such that the electronic component 1 in contact with the suction portion 2a, which is the lower end portion of 2, can be sucked and held by suction with a pressure difference from the outside. As the adsorption pressure, for example, a pressure of about −80 kPa is used.

  Further, the “adsorption release pressure” is a pressure that makes the inside of the nozzle pressure guiding passage 2b of the adsorption nozzle 2 a “positive pressure” with respect to the outside, and the electronic component 1 in the adsorbed and held state. The pressure is such that the contact with the adsorbing portion 2a can be reliably released by applying the pressure. As the adsorption release pressure, for example, a pressure of about +20 kPa is used.

  Further, as shown in FIG. 3, a filter insertion hole 64 is formed in a substantially horizontal direction in the figure so as to cross and communicate with a selective pressure guiding passage 58 formed in the upper left part of the manifold 50 in the figure. ing. The filter insertion hole 64 communicates with the outside of the manifold 50 on the right side of the drawing, and the inner diameter thereof is substantially the same as the outer diameter of the dust removing filter 60 and the outer diameter of the body portion of the mounting pin 62. It is possible to insert the dust removal filter 60 in a state of being fixed to the mounting pin 62 from the communication part to the outside. In addition, each filter insertion hole 64 communicates with each pressure output portion 53 provided in the upper portion of the manifold 50.

  As shown in FIG. 5, the mounting pin 62 has a filter insertion hole 64 that communicates with the outside of the manifold 50 when the left portion of the attachment pin 62 is inserted into the filter insertion hole 64 together with the dust removal filter 60. A flange-shaped sealing portion 62d capable of sealing the filter insertion hole 64 by being in contact with the peripheral portion is provided. Since the sealing portion 62d is provided in this way, as shown in FIG. 3, the dust removal filter 60 fixed to the mounting pin 62 is always in a fixed position due to the contact. 61 can be located. In addition, the dust removal filter 60 is positioned at the filter equipment position 61, so that the intersection with the selected pressure guiding passage 58 is covered with the dust removal filter 60.

  As shown in FIGS. 3 and 5, the portion between the sealing portion 62 d of the mounting pin 62 and the screw portion 62 a is a body portion formed with substantially the same diameter as the filter insertion hole 64. An annular recess 62b is formed in the body portion.

As an example, a lock ball plunger 63 is provided. The lock ball plunger 63 is loosened to allow the mounting pin 62 to move along the filter insertion hole 64, and is fastened and engaged (ie, locked) with the recess 62b to fix the insertion position of the mounting pin 62. Thus, the dust removal filter 64 can be reliably positioned at the filter equipment position 61.

  As shown in FIGS. 3 and 5, the mounting pin 62 is inserted into the filter insertion hole 64 at the right end portion of the mounting pin 62 and the insertion position is fixed, that is, the dust removal filter 60 is disposed. In the mounted state, a gripping portion 62c is formed that can be exposed and gripped from the filter insertion hole 64 so that the mounting pin 62 can be taken out from the outside of the manifold 50. Since the gripping portion 62c is formed in this way, the work for attaching and detaching the dust removal filter 60 can be facilitated.

  In the above description, in the manifold 50, the filter insertion hole 64 is formed in a substantially horizontal direction, and the dust removal filter 60 is equipped so as to keep its axial center in a substantially horizontal state. The present embodiment is not limited only to such a case. For example, instead of such a case, the filter 60 for dust removal may be provided so that the filter insertion hole 64 is formed downward or obliquely downward, and the axis is disposed in each direction. It may be a case.

(Dust removal filter removal procedure)
Next, in the head unit 100 having such a configuration, an attaching / detaching procedure for exchanging and cleaning the dust removing filter 60 will be described with reference to FIG.

  As shown in FIG. 3, in the manifold 50, the lock ball plunger 63 corresponding to the dust removal filter 60 to be removed is loosened, and the fixing of the mounting pin 62 is released. Thereafter, the gripping portion 62c of the mounting pin 62 is gripped, and the mounting pin 62 is extracted from the filter insertion hole 64, whereby the dust removal filter 60 fixed to the mounting pin 62 is removed from the filter mounting position together with the mounting pin 62. Take out. Furthermore, the dust removal filter 60 can be removed from the attachment pin 62 by releasing the engagement between the threaded portion 62 a of the attachment pin 62 and the inner peripheral surface 60 a of the dust removal filter 60.

  Further, when a new dust removal filter 60 is provided instead of the dust removal filter 60, as shown in FIG. 3, the screw portion of the mounting pin 62 is provided on the inner peripheral surface 60a of the new dust removal filter 60. The dust removing filter 60 is fixed to the mounting pin 62 by screwing 62a. Thereafter, the tip of the fixed dust removal filter 60 is inserted into the filter insertion hole 64 until the sealing portion 62d of the mounting pin 62 contacts the peripheral portion of the filter insertion hole 64 on the outer surface of the manifold 50. The mounting pin 62 is inserted into the filter insertion hole 64. As a result, the dust removal filter 60 is positioned at the filter equipment position 61. Thereafter, the lock ball plunger 63 in a loosened state is fastened, and the lower end portion of the lock ball plunger 63 shown in the figure is engaged with the recess 62b of the mounting pin 62 to fix the insertion position of the mounting pin 62. The filter insertion hole 64 is closed by the sealing part 62d. Thereby, the insertion position of the filter 60 for dust removal can be fixed to the filter equipment position 61.

  Further, when the dust removal filter 60 is detachably mounted as described above, for example, when the suction valve 56 is opened and the blow valve 57 is closed, FIGS. 3, the flow of air from the suction unit 2 a to the pressure output unit 53 is generated by the suction pressure guided from the pressure output unit 53 to the suction unit 2 a of the suction nozzle 2. Due to this air flow, in the dust removing filter 60 shown in FIG. 3, the inner peripheral surface 60a positioned on the pressure output unit 53 side is changed from the outer peripheral surface 60b positioned on the adsorption pressure input unit 51 side. An air flow in the direction will occur. Accordingly, dust or the like sucked from the suction portion 2a is captured mainly on the inner peripheral surface 60a side of the dust removal filter 60.

  On the other hand, when the adsorption valve 56 is in the closed state and the blow valve 57 is in the open state, contrary to the above, in FIG. 1 to FIG. Air flow to Due to this air flow, in the dust removing filter 60 shown in FIG. 3, the outer peripheral surface 60b positioned on the blow pressure input portion 52 side is changed to the inner peripheral surface 60a positioned on the pressure output portion 53 side. An air flow in the direction will occur. Therefore, even when the compressed air input to the blow pressure input unit 52 includes dust or the like, such dust is mainly captured on the outer peripheral surface 60b side of the dust removal filter 60. The Rukoto.

  Note that the control of the opening and closing operations of the respective suction valves 56 and blow valves 57 provided in the manifold 50 is performed by the control unit 9 while being correlated with the control operations of the other components in the head unit 100. .

  Further, in the present embodiment, the case where each dust removal filter 60 is provided in the middle of each selective pressure guide passage 58 in FIG. 2 is described, but the present invention is not limited to this case. Absent. For example, instead of such a case, at least each dust removal filter 60 is provided in the middle of the adsorption pressure guiding passage 54 between each adsorption valve 56 and each pressure output portion 53. It may be a case. In this way, each dust removal filter 60 is provided in the middle of each suction pressure guide passage 54, so that the suction pressure is guided to the suction portion 2a of the suction nozzle 2 and includes dust and the like. Even when air is sucked into the adsorption pressure guiding passage 54 through the adsorption unit 2a and the pressure output unit 53, the dust or the like can be captured by the dust removal filter 60, and the adsorption valve is used to remove the dust from the dust or the like. This is because 56 can be reliably protected.

  According to the above embodiment, the following various effects can be obtained.

  First, in each head nozzle 100, each suction nozzle 2 is provided with a dust removal filter 60 provided in the middle of a suction pressure passage and a suction pressure passage for sucking and holding the electronic component 1. Rather than being provided, each of the suction nozzles 2 can be attached to and detached from the manifold 50 provided with the suction valve 56 and the blow valve 57 for switching between the suction pressure and the blow pressure. Irrespective of the desorption operation, the desorption operation of each dust filter 60 can be performed.

  In addition, such a manifold 50 is originally arranged at a position where the operator can easily access the head unit 100 in consideration of the maintainability of the respective suction valves 56 and blow valves 57. By providing each of the manifolds 50 with the respective dust removal filters 60, it is possible to improve maintenance performance such as replacement and cleaning of the dust removal filters 60.

  Specifically, in the conventional head unit, the replacement frequency of the dust removal filter is once / week, the replacement work time is approximately 120 minutes / part mounting device (breakdown: (10-20 minutes / suction nozzle) × ( 10 to 20))), the head unit 100 of the above embodiment requires approximately 10 minutes of work time / component mounting device (breakdown: under the same replacement frequency) (0.5 minutes / adsorption nozzle) × (equipment number 10 to 20)), and maintenance performance such as replacement and cleaning of the dust removal filter 60 can be improved.

  Further, in the manifold 50, each dust removal filter is formed in a substantially cylindrical shape, and filtration of air containing dust or the like (that is, dust trapping) is performed between the inner peripheral surface 60a and the outer peripheral surface 60b. Since it can be performed, the filtration area can be increased without significantly increasing the size of the dust removal filter 60 compared to a conventional disc-shaped dust removal filter. Therefore, a dust removal filter capable of performing efficient filtration can be provided.

  In addition, the dust removal filter 60 is formed in a substantially cylindrical shape as described above, and the dust removal filter 60 can be attached and detached while keeping the substantially cylindrical shaft center substantially horizontal. The desorption can be performed without scattering or dropping the dust captured on the peripheral surface 60a side around the dust during the desorption. Note that such an effect is obtained even when the dust removal filter 60 is arranged and installed in a downward or obliquely downward direction and is attached and detached while maintaining the posture of the arrangement state. be able to. Further, the dust removal filter 60 is provided so that the inner peripheral surface 60a of the dust removal filter 60 is on the pressure output unit 56 side and the outer peripheral surface 60b is on the suction valve 56 side, so that dust is relatively easily deposited. The dust at the time of applying pressure can be captured and deposited on the inner peripheral surface 60a of the dust removal filter 60, and the above effect can be effectively exhibited.

  Further, the dust removal filter 60 can be inserted into the filter insertion hole 64 and removed from the filter insertion hole 64 while the dust removal filter 60 is releasably fixed to the mounting pin 62. Detachment work does not require "familiarity" and can be performed as an easier work. In particular, the attachment pin 62 is provided with a gripping portion 62c that protrudes from the outer surface of the manifold 50 when the dust removal filter 60 is installed, so that the above detaching operation can be further facilitated.

The dust removal filter 60 can be fixed to the filter equipment position 61 by engaging the annular recess 62b formed in the body portion of the mounting pin 62 with the lock ball plunger 63. When the dust removal filter 60 is removed, it can be performed by loosening the fastened lock ball plunger 63. Therefore, the desorption work of the dust removal filter 60 can be simplified.
It is to be noted that, by appropriately combining arbitrary embodiments of the various embodiments described above, the effects possessed by them can be produced.
