Description

  The present invention relates to a liquid material supply device that stores and supplies a liquid material such as a resin adhesive in a container.

In the electronic component mounting field, resin adhesives are widely used for applications such as fixing electronic components to a substrate. Liquid substances such as resin adhesives are handled in a state where they are stored in a container such as a syringe or cartridge. When supplying these liquid substances to a coating apparatus that applies to a workpiece such as a substrate, the liquid substances are not allowed to flow. The stored container is attached to a container holder provided in a discharge device, a coating device, or the like (see, for example, Patent Documents 1 and 2). The liquid substance stored in these containers is discharged from the container by air pressure, and when the liquid substance in the container is exhausted, the used container is removed from the container holder and replaced with a new container.

As a result, even when the manual lock is released due to an erroneous operation at a timing when the lever 27 should not be unlocked, the lever 27 is kept locked.

  The lever base 27 c is provided with a second fulcrum 46 at a position spaced apart from the first fulcrum 35 by a predetermined distance D. The second fulcrum 46 has a structure in which a shaft support block 46b coupled to the lower end portion of the link rod 25 is pivotally supported on the lever base portion 27c by a pin 46a. Thus, the link rod 25 is pivotally supported at one end by the second fulcrum 46 so as to be rotatable in the vertical direction. A coupling block 47 is coupled to the upper end portion of the link rod 25, and an inverted L-shaped engagement hook 48 extending upward is provided on the coupling block 47.

  The engaged portion 26 extending horizontally from the lid 18 is connected to the upper portion of the two side plates 26a by the cover portion 26b, and both ends of the engaged portion 26 are supported by the side plates 26a below the cover portion 26b. It has a structure in which a mating pin 26c is provided. In a state where both the lever 27 and the link rod 25 are upright, the engagement hook 48 is engaged with the engaged pin 26 c, whereby the lid 18 is locked to the holder main body 16 via the link rod 25 and the lever 27. The state in which the opening 30a is sealed is maintained.

  Next, the function of the lid opening / closing mechanism 17 that opens and closes the lid 18 by operating the lever 27 will be described with reference to FIG. FIG. 8A shows an operation when the lid 18 is closed. In this operation, the lever 27 is rotated downward (clockwise direction) around the first fulcrum 35 with the upper surface of the engaged pin 26c engaged with the lower surface of the engagement hook 48. Then, the link rod 25 is pushed downward via the second fulcrum 46, and the engaged portion 26 is pulled downward by the link rod 25. As a result, the lid 18 rotates about the lid hinge portion 18a, the fitting convex portion 18d is inserted into the opening 30a together with the first O-ring 33, and the inside of the container 30 is sealed.

  Then, by rotating the lever 27 upward from this state, as shown in FIG. 8B, the link rod 25 connected to the lever 27 moves upward, and the engaging hook 48 is engaged with the engaged pin 26c. The engaged portion 26 is pushed up by coming into contact with the lower surface of the cover portion 26b away from the upper surface of the cover portion 26b. Accordingly, the lid 18 rotates in the opening direction around the lid hinge portion 18a, and the fitting convex portion 18d inserted into the opening 30a of the container 30 is extracted from the opening 30a together with the first O-ring 33. It is.

That is, in the above-described configuration, the lever 27 is pivotally supported in the vertical direction with the upper end portion pivotally supported by the first fulcrum 35 fixed to the container holder 15. The link rod 25 is pivotally supported at one end by a second fulcrum 46 provided at a position spaced apart from the first fulcrum 35 by a predetermined distance D in the lever 27, and is rotatable in the vertical direction. The link member has an engaging hook 48 as an engaging portion that engages with the engaged portion 26 provided on the lid 18 at the other end. The engaging hook 48 and the engaged portion 26 engage with each other in two directions, ie, the direction in which the first O-ring 33 is inserted into the opening 30a and the direction in which the first O-ring 33 is removed from the opening 30a. It is configured as follows.

  Here, the predetermined distance D is set based on the drive stroke of the link rod 25 required for the opening / closing operation of the lid 18. Then, by appropriately setting the lever ratio between the predetermined distance D and the entire length of the lever 27, the operating force applied to the grip portion 27a is expanded according to the lever ratio, and the link rod 25 is driven up and down with a large force. Be able to.

  By adopting such a configuration, even when a large container 30 is used, the container 30 can be sealed and opened with the lid 18 with good operability. That is, when a large container is a target, the size of the sealing O-ring is increased, and a large force is required to fit and remove the O-ring from the opening of the container. Even in such a case, the cover 18 can be easily opened and closed with a small force by employing a mechanism for driving the link rod 25 by the lever 27 as shown in the present embodiment. ing.

  Next, the configuration of the control system will be described with reference to FIG. In FIG. 9, an operation / input unit 51 such as a keyboard and a mouse is connected to the control unit 50, and the substrate transport mechanism 3, the coating head moving mechanism 6, and the like are input by operation commands and data input from the operation / input unit 51. The operation of the coating head 9 is controlled. The notification unit 56 notifies a predetermined item such as the posture state of the container holder 15 detected by the sensor 23 by a display monitor, an indicator lamp, or the like according to a command from the control unit 50. Air pressure is supplied to the container 30 and the lever lock cylinder 36 via regulators 54 and 55, respectively. A valve 53 is provided in an air pressure supply path from the pressure source 52 to the regulators 54 and 55, and the air pressure is supplied to the container 30 and the lever lock cylinder 36 by controlling the valve 53 by the control unit 50. Be controlled.

  Next, with reference to FIG. 10, the movement operation | movement of the container holder 15 at the time of replacing | exchanging the container 30 is demonstrated. In the process of continuing to discharge the resin adhesive 31 from the container 30 and supplying it to the coating head 9, when the resin adhesive 31 in the container 30 is exhausted, a container replacement operation is performed. In the container replacement operation, as shown in FIG. 10, the Y-axis table 11 is first driven to move the Y-direction moving member 12 in the Y direction.

  As a result, the container holder 15 is moved to the replacement position where the holder fixing mechanism 20 and the hinge portion 19 are mounted via the base bracket 14 and can be easily operated from outside the apparatus in the vicinity of the cover opening 2b. Moving. Then, the holder fixing mechanism 20 is released, and the container holder 15 is rotated around the hinge portion 19 to bring the container holder 15 into an inclined posture as shown in FIG. Next, the lid opening / closing mechanism 17 is released, the lid 18 is opened from the holder main body 16, and an operation of taking out the used container 30 from the holder main body 16 and replacing it with a new container 30 is executed.

  In the above configuration, the Y-direction moving member 12 is a horizontal moving member that is mounted with the holder fixing mechanism 20 and the hinge portion 19 and moves in the horizontal direction. The Y-axis table 11 moves the Y-direction moving member 12 within a predetermined work area when supplying the liquid substance, and moves the Y-direction moving member 12 to a predetermined replacement position when replacing the container 30. It is a horizontal movement means to make it.

By adopting a configuration in which the container holder 15 is moved to the replacement position and inclined as described above, the container 30 can be attached to and detached from the container holder 15 with good operability. At the same time, it is not necessary to secure a space for attaching / detaching the container 30 to / from the container holder 15 in the apparatus as compared with the conventional apparatus for attaching / detaching the container in the apparatus. Accordingly, even when a large container having a large height is targeted, there is an advantage that the apparatus size can be reduced.

  Next, details of the opening operation of the lid 18 in the container replacement operation described above will be described with reference to FIGS. FIG. 11 shows a state in which the container holder 15 is inclined by releasing the holder fixing mechanism 20 after the tank head 7 is pulled out to the replacement position. That is, in this state, the container 30 has the flange portion 30b supported from below by the upper portion 16b, and the fitting convex portion 18d is inserted into the opening portion 30a of the container 30 together with the first O-ring 33, and the flange portion 30b. A second O-ring 34 is pressed against. The lid 18 is locked by the lid opening / closing mechanism 17.

  When opening the lid 18, first, the operation / input unit 51 is operated to release the lever lock by the lever lock cylinder 36. That is, the lever lock cylinder 36 is driven so that the rod 36a is immersed in the direction of the back side of the drawing. Next, the user holds the grip portion 27a of the lever 27, puts a finger on the finger hook portion 38a and pushes it down, and performs an operation of sliding the slide plate 38 downward as shown in FIG. As a result, the latching end portion 37a is pushed downward by the extending portion 38c to disengage from the position where the lever intermediate portion 27b is locked, and the locking of the lever 27 by the hook 37 is released.

  Thereafter, the lid 18 is opened. That is, the grip portion 27a is gripped and pulled to the near side (right side in the figure), and the lever 27 is rotated upward as shown in FIG. As a result, the lever 27 is rotated around the first fulcrum 35, and the link rod 25 is moved upward by the movement of the second fulcrum 46 due to this rotation. As the link rod 25 moves upward, the engagement hook 48 comes into contact with the cover portion 26b and pushes it up.
