Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is directed to maintaining the relative positional relationship between a first part of a first member and a second part of a second member, and The present invention relates to a method of joining a plurality of members, in which two members are joined to each other in a state in which two members are brought into close contact with each other by a joining force generated in the Z-axis direction by a joining force generating means.

[Prior Art] In recent years, print heads that eject ink to print on paper using the so-called bubble jet method, which heats the ink to form bubbles, have become advantageous in improving printing accuracy. Therefore, it has been developed and put into practical use.

The assembly device that assembles such a bubble jet print head uses a heater to heat the ink and an ejection port that ejects the foamed ink heated and boiled by the heater toward the paper. , which requires accurate positioning on the micron order. For example, the printing accuracy is approximately 360 dpi (dots pe
To achieve a high accuracy of r 1nch), approximately 4.5
Sixty-four discharge holes must be arranged at equal intervals in a range of 1.5 mm, and the arrangement pitch in this case is as fine as about 70 microns.

Here, the formation of discharge holes at such extremely small intervals can be achieved by, for example, using an ultra-precision processing device such as a laser processing machine to create a predetermined allowable height on the orifice plate attached to the front surface of the top plate member.

This first positioning mechanism 27 is arranged along the X-axis on the heater board 102 of the top plate 104, that is, along the arrangement direction of the corresponding discharge ports 106 and discharge heaters 112 so that they match. It includes an X-axis positioning section 27A that performs positioning, and an X-axis positioning section 27B that performs positioning along the y-axis direction, that is, so that the rear surface of the orifice plate 108 is in close contact with the front end surface of the heater board 102. .

(Description of the X-axis positioning section 27A) First, in the X-axis positioning section 27A, one suction member 26b, which is on the near side in the figure in this embodiment, is defined as the reference side, and the suction member 26b on the reference side is defined as the reference side. Member 26b is fixed to main body 26a. On the contrary,

The connecting member 26h is supported by the guide shaft 26i via a slide guide 26j so as to be movable along the X-axis direction.

On the other hand, a first drive cylinder (not shown) is mounted on the main body 26a, facing the intermediate portion of the connecting member 26h.
is installed. The piston rod of this first drive cylinder protrudes so as to be driven forward and backward along the X-axis direction, and its tip is connected to the above-mentioned connecting member 26h.

In this way, by reciprocating the corresponding piston rod at high speed by this first driving cylinder, the connecting member 2

The outer ends of these connecting pieces 26p and 26Q are connecting members 26r and 2 extending along the y-axis direction.
The front end of the 6s is attached.

On the other hand, second drive cylinders 26t extending along the y-axis direction are disposed at both end edges of the main body 26a. Each piston rod 2 of these second drive cylinders 26t
6u protrudes so as to be driven forward and backward along the y-axis direction,
These tips are connected to the rear ends of the aforementioned connecting members 26r and 26s, respectively.

In this way, the second driving cylinder 26t reciprocates the corresponding piston rod 26u at high speed, so that the engaging pieces 26m and 26n connected via the connecting pieces 26p and 26q, respectively, are moved along the y-axis. The top plate 10 is driven back and forth at high speed along the direction, that is, vibrated, so that the orifice plate 108 is brought into close contact with the front end surface of the heater board 102.

Since the mounting mechanism 26 is configured in this manner, the top plate 104 is suctioned and held by the pair of suction members 26b and 26c.
is moved to a predetermined position above the heater board 102 based on the drive control of the first position adjustment mechanism 14, and by releasing the suction, the top plate 104 is moved to a predetermined position above the heater board 102.
At this fallen position, the top plate 104 is moved to the heater board 1 by the operation of the X-axis positioning section 26A.
The position along the X-axis with respect to 02 is defined, and the position along the y-axis with respect to the heater board 102 is defined by the operation of the X-axis positioning section 26B. Incidentally, the position adjustment operation in the mounting mechanism 26 will be explained in detail later.

<Description of the second positioning mechanism 33> Next, the second positioning mechanism 33 is used to attach the base member 208, to which the heater board 102 is attached in advance, onto the second y-axis stage 32 in an accurately positioned state.

The heater board mounting portion 208b is integrally formed with a protruding upper surface of which the heater board 102 is fixedly mounted.

Note that this heater board 102 is previously attached and fixed to the heater board mounting portion 208b with a predetermined accuracy. Therefore, this heater board 102
By positioning the base member 208 to which the heater board 1 is attached relative to the second y-axis stage 32,
02 will be positioned with respect to the second y-axis stage 32.

They are integrally formed and lined up along the axial direction.

By abutting one side edge of the main body portion 208a of the base member 208 along the y-axis with these X-axis positioning protrusions 33d and 33e, the position of the base member 208 along the X-axis is uniquely defined. , the position will be determined in the X-axis direction.

On the other hand, in this way, these X-axis positioning protrusions 33d, 3

An X-axis regulating lever 33f is provided. The X-axis control lever 33f has its base end rotatably supported around a first support shaft 33g, and is supported by a first torsion spring 33h.
As a result, in the figure, a counterclockwise rotation biasing force is applied. The abutting end of the X-axis regulating lever 33f is set to abut approximately the center of the other side edge of the base member 208.

(Description of the X-axis positioning section 33B) Also, on this positioning table 33c, the X-axis positioning section 3
3B, one X-axis positioning protrusion 33i protruding upward is integrally formed in close proximity to one X-axis positioning protrusion 33e. The base member 208 has a predefined position in the X-axis direction on this X-axis positioning protrusion 33i.

By abutting the front edge of the body portion 208a along the X axis, the position of the base member 208 along the y axis is uniquely defined, that is, the y axis direction is determined.

On the other hand, in order to force the tip edge of the main body portion 208a of the base member 208 along the X-axis to come into contact with the X-axis positioning projection 33i, the An abbreviated y-axis regulating lever 33j is disposed so as to be able to come into contact with the rear end edge of the base member 208 on the opposite side from the leading edge thereof. This y-axis regulating lever 33j is rotatably supported around the second support shaft 33 at the intermediate portion (that is, the bent portion forming the L-shape), and is supported by the second torsion spring 33g. In the figure, it is receiving a rotation biasing force in a counterclockwise direction. The rear end of the y-axis regulating lever 33j is set to come into contact with a substantially central portion of the rear edge of the base member 208.

Here, when the base member 208 is attached to and detached from the positioning table 33c, the urging force by the X-axis and y-axis regulating levers 33f and 33j must be released. Therefore, in this embodiment, a release mechanism 33D is provided. It is being

A piston rod 33n protrudes from the release cylinder 33m so as to move forward and backward along the X-axis direction and passes through the positioning base 33c. The clocks are taken out in a state slightly protruding from the top surface of the positioning base 33c through the through holes 3sp and 33q formed to extend along the X-axis regulating lever 33f and the Y-axis regulating lever 33j, respectively.

The shaft regulating levers 33j are rotated counterclockwise by the biasing forces of the corresponding torsion springs 33h and 33j2, respectively, to position and hold the base member 208.

On the other hand, the release cylinder 33m urges the piston rod 33n to protrude in the released state. As a result, the pair of release bins 33r and 33s are respectively
It comes into contact with the shaft regulating lever 33f and the y-axis regulating lever 33j, and rotates them clockwise against the biasing forces of the corresponding torsion springs 33h and 33ρ. Therefore,
The respective contact ends of the X-axis regulation lever 33f and the y-axis regulation lever 33j are separated from the other side edge and the rear end edge of the base member 208, and in this way, the positioning and holding of the base member 208 is released. It will happen.

(Description of 2-axis positioning section 33C) On the other hand, as shown in FIG. 6B, the above-mentioned Z-axis positioning section 33G protrudes downward from the lower surface of the tip of the base member 208 and extends in the X-axis direction. A pair of first and second protrusions 33t and 33u arranged in parallel along the
Although only the first protrusion 33t is shown, the positions of the first and second protrusions 33t and 33u are indicated by broken lines in FIG. 6A. ), and a third protrusion 33v that is formed in the center of the upper surface of the rear end of the positioning table 33c and protrudes upward.

Here, the protrusion lengths of these first to third protrusions 33t to 33v are accurately defined in advance so that they are the same. As a result, the first and second protrusions 33t, 33u
comes into contact with the top surface of the positioning table 33c, and the third protrusion 33v comes into contact with the bottom surface of the base member 208.
The position of the base member 208 on the positioning table 33c along the Z-axis direction is accurately defined.

In this embodiment, in order to reliably achieve the above-mentioned contact state, the base member 208 is placed on the positioning table 3.
A suction mechanism 33E that sucks toward 3c is provided. As shown in FIG. 6B, this suction mechanism 33E is disposed on a positioning table 33c, and is designed to connect a ring-shaped suction pad 33w with an open top surface and a suction source (not shown). , and a connecting pipe 33x formed to penetrate inside the positioning table 33c.

Here, the height of the suction pad 33w is set slightly higher than the height of each of the three projections 33t, 33u, and 33v described above. As a result, base member 2.
08 is placed on the positioning table 33c, the open end of the suction pad 33w comes into close contact with the lower surface of the base member 208 over the entire circumference. Then, by starting a suction source (not shown), the base member 208 is forcibly drawn toward the positioning table 33c, and as a result, the first and second protrusions 33t, 33u are securely attached to the upper surface of the positioning table 33c. A state in which the third protrusion 33v contacts the lower surface of the base member 208 reliably is forcibly set.

By configuring the second positioning mechanism 33 in this way, the base member 208 can be placed on the positioning table 33c.
are precisely positioned along the X-axis direction, y-axis direction, and z-axis direction. As a result, in this embodiment, the top plate 104 is connected to the heater board 102.
When attaching the heater board to the heater board, it is only necessary to define the relative position of the top plate 104 with respect to the heater board 102 via the first positioning mechanism 27.

Description of the bonding force generation mechanism 34> Next, the top plate 104 is positioned on the heater board 102.
The bonding force generating mechanism 34 that generates bonding force between the two when placed will be described with reference to FIG. 6B.

This bonding force generating mechanism 34 includes a guide shaft 34a attached to the tip of the main body 33a described above so as to be able to move up and down, and the upper end of this guide shaft 34a is fixed to the lower surface of the positioning table 33c. There is. Further, a washer 34b for adjusting the bonding force is screwed onto the upper end of the guide shaft 34a.
By rotating b, the guide shaft 34a of this
The axial position will change.

On the other hand, a coil spring 34c for generating bonding force is wound around the outer periphery of the guide shaft 34a, and the upper end of the coil spring 34c is engaged with the lower surface of the washer 34b, and the lower end is attached to the main body 33a. It is fixed on the top surface. Here, this coil spring 34c is
Supporting the weight of the positioning table 33c and the parts on it, it has shrunk to a certain extent, but by further contracting by a predetermined amount from this initial setting state where it has shrunk to a certain extent, a predetermined elastic repulsive force is generated. This elastic repulsive force is defined as the bonding force.

Since the bonding force generating mechanism 34 is configured in this way, when placing the top plate 104 on the heater board 102,
The top plate 1
04 against the heater board 102, the above-mentioned predetermined bonding force is generated between the top plate 104 and the heater board 102.

Note that this change in bonding force is achieved by rotating the above-mentioned washer 34b and biasing it along the axial direction of the guide shaft 34a, thereby changing the initially set length of the coil spring 34c. .

Description of Calibration Chart 78> Here, as shown in FIG. 7A, a calibration chart 78 is fixed on the positioning base 33c of the second positioning mechanism 33, which will be used in a calibration operation that will be explained in detail later. ing. This calibration chart 78 is precisely arranged at a position separated by a predetermined distance along the It is formed into a rectangular parallelepiped shape.

In particular, the formation state is such that a first calibration surface 78a is defined from the front end surface of this rectangular parallelepiped-shaped calibration chart 78, and this first calibration surface 78a extends vertically exactly along the X-axis direction. In addition, it is set to extend within the same vertical plane as the front end surface of the heater board 102. Further, from the top surface of this rectangular parallelepiped-shaped calibration chart 78, a second calibration surface 7
8b is defined, and this second calibration surface 78b is exactly Z
The heater board 1 extends horizontally along the axial direction.
It is set to extend within the same horizontal plane as the upper surface of 02. Further, a third calibration surface 78c is defined from the side surface of the rectangular parallelepiped-shaped calibration chart 78 on the side where the heater board 102 is disposed, and this third calibration surface 78c is exactly perpendicular to the y-axis direction. It is set to extend to

Here, a calibration reference point 78d is defined by the intersection of the first to third calibration planes 78a to 78c. As a result, when this calibration chart 78 is photographed by the first position detection mechanism 40, only the first calibration surface 78a is photographed, and this calibration reference point 78d is located on the screen 40A, as shown in FIG. 7B. The image is taken as the intersection of the corners located in the upper right corner of
Furthermore, when photographing is performed using the second position detection mechanism 42, only the second calibration plane 78b is manipulated, and this calibration reference point 78d is located at the lower right corner of the screen 42A, as shown in FIG. 7C. The image will be taken as the intersection of the corners.

In addition, in FIG. 7A explaining the calibration chart 78, symbols 80a and 80b indicate the top plate 104 and the heater board 102.
The adhesive used to temporarily attach the and to each other is shown. These adhesives 80a.

80b is formed to have an ultraviolet curing property that hardens when irradiated with ultraviolet rays, and is set to be attached in advance to both ends of the rear edge of the heater board 102, respectively, as shown in the figure. .

(Hereinafter, blank space) (Description of the method for assembling the head nozzle 10 in the assembly device 10) Below, with reference to FIG. A method of assembling the head nozzle 10 to which a method of joining multiple members is applied will be described.

Schematic procedure of this assembly method> First, the schematic procedure of this assembly method will be explained with reference to the flowchart shown in FIG.

First, when an assembly operation is instructed, a variable N indicating the number of assembly operations is set to "1" in step S10. Then, in step S12, each axis stage 18, 20,
Initial setting of the drive motors 22, 28, 30.32 is performed, and subsequently, in step S14, the origin of the drive motors of each axis stage 18° 20.22, 28, 30.32 is found. By executing these steps S12 and S14, each axis stage 18, 20,
22, 28, 30, and 32 can be accurately moved to any predetermined position with respect to the surface plate 12.

After that, in step 316, the amount of deviation between the detection positions of the first and second position detection mechanisms 40.42 is calculated in advance as a calibration amount ΔX (for
8 to calibrate the deviation in the detection positions of the first and second position detection mechanisms 40 and 42. When the calibration operation in step S16 is completed, the variable N is reset to "1" in step S18, and the process proceeds to step S20.

In this step S20, the base member 208 to which the heater board 102 is attached in advance is moved from the supply position to the second position adjustment mechanism 1 via a supply robot (not shown).
6 on the second positioning mechanism 33. Then, in the subsequent step S22, the supplied base member 208 is accurately positioned.

Here, in this positioning operation, based on the operation of the second positioning mechanism 33 described above, in addition to the operation of positioning the main body 33a in three axial directions, An operation of accurately measuring the amount of deviation (xo) of the discharge heater 112C located in the middle serving as a reference from the assembly work position α with respect to the X-axis direction which is the arrangement direction of these discharge heaters 112a to 112e; In order to measure the amount of deviation based on the image taken with the second ITV camera 42g°, in order to accurately focus the image, the correct position in the Z-axis direction relative to the assembly work position α on the top surface of the heater board 102 must be determined. This includes a positioning operation.

Following this supply and positioning operation of the heater board 102, in step S24, the top plate 104 is supplied from the storage position to the first positioning mechanism 27 of the first position adjustment mechanism 14 via a supply robot (not shown). Then, in step S26, the supplied top plate 104 is moved to the base member 208, which was previously positioned via the second positioning mechanism 33 in step S22.
Temporarily place it on the heater board 102 above.

In this way, the heater board 102 and the top plate 104 to be assembled are supplied together, and the heater board 1 is positioned.
When the top plate 104 is temporarily placed on 02, step 328
In step S30, in a state where the relative positional relationship between the two along the X-axis direction is accurately defined, an operation of bonding the two is performed. When the bonding operation is completed, in step S32, the assembly as a finished product is discharged to a finished product discharge position via a robot (not shown).

The details of these X-axis positioning operations and bonding operations will be explained later as subroutines.

Then, in step S34, it is determined whether all assembly operations have been completed and all finished product ejection operations have been completed.If it is determined No in this step S34, that is, there is no assembly operation yet. If the operation is not completed and it is determined that the assembly operation is in progress, the process proceeds to step S36, where the variable N is incremented by "1", and in step S38, it is determined whether the variable N has reached a predetermined number. to judge. In this step S38, if it is determined No, that is, if it is determined that the number of assembly executions N is less than a predetermined number of times, specifically, if the number of assembly executions N is less than a predetermined number of times after the first calibration operation is performed, If it is determined that there is a Returning to step S20, the following assembly control procedures are repeatedly executed.

On the other hand, if it is determined YES in step S38, that is, if it is determined that the number of assembly executions N is the predetermined number of times after the earliest calibration operation, the environmental change corresponding to the temperature change Based on this, there is a possibility that the above-mentioned calibration amount ΔX has changed, and in order to perform the calibration operation again and newly calculate this calibration amount ΔX, the above-mentioned step S16 is performed.
Return to , and repeat the following assembly control procedures.

In other words, if the assembly accuracy is on the order of millimeters,
First, execute the above-mentioned calibration operation, and the obtained calibration amount ΔX,
No problem will occur even if it is used throughout the entire working period of the day, but when assembly accuracy on the order of microns is required, as in this example, the calibration amount due to the temperature change described above may be required. Changes in ΔX will greatly affect assembly accuracy. On the other hand, in view of the above-mentioned circumstances, it is preferable to perform this calibration operation for each assembly operation. However, if a calibration operation is performed every time an assembly operation is performed in this way, the assembly time will be increased, the assembly efficiency will be reduced, and the cost of the product will be adversely affected. In this way, it is possible to maintain both assembly precision and assembly efficiency (in this embodiment, the calibration operation is set to be re-executed every predetermined number of assembly operations).

Here, after performing the calibration operation in this step S16, the variable N is reset to "1" in step S18, so the number of assemblies in this assembly operation is counted as the -th time again, and In operation, the number of assemblies is incremented by "1".

Furthermore, if it is determined YES in the above-mentioned step S34, that is, if it is determined that all assembly operations have been completed and all finished product ejection operations have been completed, at this point, this assembly Terminate the control procedure.

The individual control procedures outlined in the above-mentioned assembly control procedure will be explained in detail below as subroutines.
In fact, as already mentioned above, in order to achieve high-density printing accuracy of 360 dpi, an orifice plate 108 in which a large number of discharges 0106 are formed at equal intervals over a length of about 4.5 mm is integrated. At least 64 discharge ports 1 are placed on a heater board 102 on which 68 discharge heaters 112 are formed at a similar arrangement pitch.
06 and the discharge heater 112 are assembled in a state that corresponds to each other, and extremely accurate positioning operation and delicate application of joining force are required.

However, in the following explanation of the assembly control procedure, if the 68 discharge ports 106 and the large number of discharge heaters 112 are illustrated and explained as they actually are, the explanation will become unclear and complicated. Therefore, in the following description, as shown in FIG. On the heater board 102, there are five discharge heaters 112, specifically, first to fifth discharge heaters 112a to 112.
The explanation will be given in a simplified state, with the shape e being formed.

<Detailed Description of Each Subroutine> Various subroutines in the assembly control procedure briefly described with reference to FIG. 8 will be described in detail below.

(Explanation of adhesive application position) First, when the heater board supply operation is started, a supply robot (not shown) grasps and takes out the base member 208 to which the heater board 102 is attached in advance from the storage attachment 1. , and transported onto an adhesive application jig (not shown).

Then, the predetermined position of the heater board 102 on the base member 208 placed on this adhesive application jig, in detail,
As shown in FIG. 7A, adhesive 80a is applied to both sides of the rear edge of the heater board 102 via an adhesive application mechanism (not shown).
80b is applied respectively.

Note that, as described above, the adhesives 80a and 80b are composed of an ultraviolet curable adhesive that cures, that is, exhibits adhesive strength, by being irradiated with ultraviolet rays. In other words,
At this point of application, these adhesives 80a and 80b do not exhibit any adhesive properties and function only as liquids.

(The heater board 1 of the top plate 104 in step 528
02) Next, referring to the flowchart shown in FIG. 10 and FIGS. 11A to 13, the top plate 1 in step 828 is
The positioning operation in the X-axis direction on the heater board 102 of No. 04 will be explained.

In the above-described temporary placement operation of the top plate 104, the mounting mechanism 26 is moved to the designed mounting position by driving the first position adjustment mechanism 14, and then this mounting is performed by moving the mounting mechanism 26 to the designed mounting position. This temporary placement operation is performed by dropping the top plate 104 onto the heater board 102 and positioning it in the designed mounting position described above.

Here, as already mentioned above, the arrangement pitch of the discharge ports 106 formed in the orifice plate 108 of the top plate 104 and the discharge heater 112 formed on the heater board 102 is on the order of microns, so In addition to the absolute positioning described above (by performing the relative positioning of the discharge port 106 with respect to the discharge heater 112), the discharge heater 112 and the discharge port 106 that correspond to each other are actually aligned with a predetermined positional accuracy. A positioning operation must be performed so that these discharge ports 10 are combined with each other.
6 and discharge heater 112 are set in the X-axis direction, the heater board 102 of this top plate 104
It is specified that the final alignment for is performed only along the X-axis direction through image processing.

First, when this X-axis alignment operation is started, step 5
At 28A, the top plate 104 is shifted to one side. That is,
In this biasing operation, as shown in FIG. 11A, the cylindrical ink receiver on the top plate 104 has an opening 118 that is connected to both suction members 2
11B, the movable suction member 26c is moved from the fixed suction member 26 to
b, and the opening 118 of this ink receiver abuts against the fixed suction member 26b. Then, as shown in FIG. 11C, the movable suction member 26c is returned to its original position,
As shown in FIG. 11D, both suction members 26b and 26c are installed integrally, that is, by driving the machine m26 as a whole,
By moving the top plate 104 to a predetermined position, the shifting operation of the top plate 104 is completed.

When the shifting operation of the top plate 104 is completed, in step 528B, as shown in FIG. 12, the heater is An image of the front surface of the orifice plate 108 attached in front of the top plate 104 temporarily placed on the board 102 is transmitted to the first focus state detector 48 . Then, in step 328C, the first focus state detector 48 moves the heater board 102 along the y-axis direction so that a focus state is achieved, that is, in focus.
and move the top plate 104 integrally (and drive the second y-axis stage 32 to move).

Here, in this focusing operation, in the positioning operation of the heater board 102 described earlier, the first I
Since the focus of the TV camera 40g is substantially on the front surface of the orifice plate 108, this focusing operation can be completed within an extremely short time, and the front surface of the orifice plate 108 is outside the focusing range. This will surely prevent the focusing operation from becoming impossible.

When the focusing operation is completed in step 528C, the first ITV camera 40g in the first position detection mechanism 40 is fixed to the front side of the top plate 104 temporarily placed on the heater board 102 in step 528D. The front surface of the orifice plate 108 is photographed. The image of the orifice plate 108 taken by the first ITV camera 40g has been focused as described above, so it is a clearly focused image as shown in FIG. ing.

After this, in step 528H, step 328C
The captured image is transmitted to the image processing device 44 via the first signal converter 46, and in step 528F,
Based on the image taken through the first ITV camera 40g, the distance XI4 from the center of the screen to the center position of the discharge hole 106 that is determined to be closest to the central discharge heater 112C is electrically calculated. Measure. Here, as described in the positioning operation of the heater board 102 in step S22, the center line of the screen corresponds to the assembly work position a, and this distance XH corresponds to the assembly work position α
It represents the amount of deviation along the X-axis direction from to the discharge hole 106 that will be combined with the central discharge heater 112C.

Discharge port 1 corresponding to the central discharge heater 112C described above
After measuring the amount of deviation XH from the center line of 06, in step 528F, the discharge heater 11 located at the center
20 and the corresponding discharge port 106 vertically, it is necessary to move the top plate 104 including the orifice plate 108 in which the discharge port 106 is formed along the X-axis direction. The amount of movement Xy is calculated from the equation shown below.

X D = X G - XH + ΔX Next, in step 328G, it is determined whether or not this movement amount XT is smaller than the adjustment standard range C for X-direction alignment stored in advance on the data disk. In this step 328G, if it is determined to be YES, that is, if it is determined that the movement amount XT is smaller than the adjustment standard range C, the control unit 38 controls the heater board 102
It is determined that the positions in the X-axis direction of each discharge heater 112 and the discharge hole 106 formed in the orifice plate 108 of the top plate 104 match each other, and the control procedure for this X-axis direction positioning operation is ended. and return to the main routine.

On the other hand, if it is determined No in step 528G described above, that is, if it is determined that the movement amount Xa is larger than the adjustment standard range C, then the first X-axis drive stage 18 is Then, the top plate 104 is moved by an amount corresponding to the movement amount XT, and the process returns to step 528D described above.

By positioning the top plate 104 with respect to the heater board 102 in this way, the heater board 102
The discharge heater 112C located in the center of 2 and the top plate 104
The discharge heater 11 in the orifice plate 108 of
The mutual center line with the discharge port 106 closest to 2c is
They will match in the X-axis direction.

In this way, a series of positioning operations between the top plate 104 and the heater board 102 along the X-axis direction are completed, and the control procedure returns to the original main routine.

(The heater board 1 of the top plate 104 in step S30
02) Next, with reference to the flowchart shown in FIG. 14 and FIG. 15, step S3
The operation of adhering the top plate 104 onto the heater board 102 in 0 will be described.

When the positioning operation of the top plate 104 with respect to the heater board 102 in the X-axis direction in step S28 described above is completed, first, in step 530A, the first two-axis stage 20 in the first position adjustment mechanism 14 is activated, The entire first positioning mechanism 27, and thus the first and second suction members 26b and 26c, are lowered by a predetermined amount D7 along the X-axis direction. These first and second suction members 26
b and 26c will come into contact with the top plate 104 during the descent, and the top plate 104 that has come into contact with it will be connected to the joining force generating mechanism 34 with the heater board 102 integrally below it. It is pushed down against the biasing force of the coil spring 34c.

Here, the predetermined descending amount DF of the first Z-axis stage 2o described above is caused by the depression of the top plate 104 and the heater board 102 accompanying this descending, which causes the coil spring 34 to
The biasing force generated at c is applied to the top plate 104 and the heater board 10.
2 is set to a value sufficient to act as a predetermined bonding force.

In this manner, in a state where a predetermined bonding force is generated between the heater board 102 and the top plate 104, step 530
At B, the ultraviolet light source 58 emits ultraviolet light. The ultraviolet rays are brought to a pair of ultraviolet-transparent suction members 26b, 26c via a pair of light guides 56, and are irradiated onto adhesives 80a, 80b after passing through them.

As a result, since these adhesives 80a and 80b have ultraviolet curing properties, these adhesives 80a.

80b starts to harden, that is, exhibits adhesive properties. That is, the heater board 102 and the top plate 104 are in close contact with each other with a predetermined bonding force, and the adhesives 80a, 80
They will be bonded to each other via b.

As mentioned above, when changing the bonding force in this bonding force generating mechanism 34, rotate the washer 34b,
This is achieved by changing the amount of deformation of the coil spring 34c by moving the guide shaft 34a along the axial direction.

After that, in step 530C, wait for a predetermined time to elapse and wait for the adhesives 80a and 80b to be completely cured, and then in step 530D, the first two-axis stage 20 in the first position adjustment mechanism 14 is Start the
The entire first positioning mechanism 27 is therefore
The suction members 26b and 26c are raised along the Z-axis direction by an amount of rise Ua that is the same as the amount of fall Dr mentioned above. As a result, the first and second suction members 26b and 26c
It will rise to a position far above from 4 and wait.

In this way, the series of bonding operation control procedures is completed,
Return to the original main routine.

As detailed above, by carrying out the assembly device 10 of this embodiment and the assembly method in this assembly device 10,
Heater board 102 and top plate 104 which are microfabricated parts

Particularly, in the above-mentioned embodiment, this assembly device 10
This makes it possible to eliminate manual operations from the entire assembly process and achieve fully automatic assembly. As a result,
According to this assembly device 10, after the heater board 102 as the first member and the top plate 104 as the second member are aligned, in detail, the heater board 102
After aligning the upper discharge heater 112C and the discharge holes 106 formed in the orifice plate 108 of the top plate 104 so that they coincide with each other along the X-axis direction, the heater board 102 and the top plate 104 are bonded together. In doing so, the bonding force between the two is also automatically generated in the bonding force generating mechanism 34 through an automated bonding force generating operation.

As a result, according to this embodiment, the bonding force between the heater board 102 and the top plate 104 is generated in a constant state regardless of the operator's feeling, and the bonding force is constant, and The distance between the two becomes finely constant, thus improving the reliability of the product.

In addition, even if a worker is replaced, the joining force generation action by this worker is eliminated, eliminating variations in joining force due to individual differences in work methods, improving product reliability. It will be possible to do so.
