As depicted in figs. 1 and 2, glue spreader according to the present invention comprises framework 10, workbench 20, saddle 30, the mobile guide member 40 of a pair of supporting, a supporting member 50, head unit 60 and control module (not shown).Workbench 20 is arranged on the framework 10 in the mode that moves along X-direction or Y direction.Saddle 30 is installed on the workbench 20, and put on saddle 30 the substrate Building S.Supporting mobile guide member 40 is installed on the both sides of saddle 30 in the mode of extending along Y direction.Supporting member 50 is installed in saddle 30 tops by this to the mode that supports mobile guide member 40 supportings with two ends of a supporting member 50, and extends along X-direction.Head unit 60 is installed supporting member 50 to the end in the mode that moves along X-direction, and comprises nozzle 73 and laser displacement sensor 71.Control module control fluid sealant coating operation.A plurality of supporting members 50 can be arranged on the framework 10 along Y direction and the mode that moves along the mobile guide member 40 of supporting.A plurality of head units 60 can be installed to a stature supporting member 50.
As shown in Figure 2, head unit 60 comprises: first supporting member 61; Second supporting member 62, it is to be supported by first supporting member 61 along the mobile mode of Z-direction (vertical direction of Fig. 2); And the 3rd supporting member 63, its in the mode that moves along Z-direction by 62 supportings of second supporting member.
Second supporting member 62 is provided with laser displacement sensor 71.This laser displacement sensor 71 comprises emission element and receiving-member, emission element emission laser, and the spaced apart preset space length of receiving-member and emission element, and receive from substrate S laser light reflected.Therefore laser displacement sensor 71 will record the gap between substrate S and the nozzle 73 corresponding to forming the position and the signal of telecommunication that produces outputs to control module from emission element emission and from the image of substrate S laser light reflected.
The 3rd supporting member 63 is provided with: syringe 72, and it is filled with fluid sealant; Nozzle 73, it is arranged at contiguous laser displacement sensor 71 places and discharges fluid sealant; And communicating pipe 74, it allows that syringe 72 and nozzle 73 communicate with each other.
For example, first driver element 81 comprises that first CD-ROM drive motor 811 and first driving shaft, 812, the first driving shafts 812 connect first CD-ROM drive motor 811 and second supporting member 62.When operation first CD-ROM drive motor 811, second supporting member 62 moves along Z-direction individually with respect to first supporting member 61.
Further, second driver element 82 comprises that second CD-ROM drive motor 821 and second driving shaft, 822, the second CD-ROM drive motors 821 are fixed to second supporting member, 62, the second driving shafts 822 second CD-ROM drive motor 821 and the 3rd supporting member 63 are connected.When operation second CD-ROM drive motor 821, the 3rd supporting member 63 moves along Z-direction individually with respect to second supporting member 62.
At this, second CD-ROM drive motor 821 of second driver element 82 is fixed to second supporting member 62.Therefore, when second supporting member 62 by the operation of first driver element 81 when Z-direction moves, be fixed to second CD-ROM drive motor 821 of second supporting member 62 and be connected to the 3rd supporting member 63 of second CD-ROM drive motor 821 along with second supporting member 62 moves along Z-direction together.
Simultaneously, between second driving shaft 822 of second driver element 82 and the 3rd supporting member 63, be provided with coupling 64, so that second driving shaft 822 is connected with the 3rd supporting member 63.This coupling 64 comprises first coupling member 641 and second coupling member 642.First coupling member 641 extends along Y direction from the upper end of the 3rd supporting member 63.Second coupling member 642 extends towards first coupling member 641 from the bottom of second driving shaft 822 along Y direction, and place first coupling member 641 below.Therefore, the 3rd supporting member 63 hangs for 62 times from second supporting member by means of first coupling member 641.
This structure is allowed when the operation of second supporting member 62 by first driver element 81 moves down, the 3rd supporting member 63 is along with second supporting member 62 moves down together, but prevented to continue to move down when nozzle 73 touches the upper surface of substrate S.Therefore, under the state that the 3rd supporting member 63 stops, second coupling member 642 separates with first coupling member 641, and second supporting member 62 moves down.Further, when nozzle 73 touched the upper surface of substrate S and second coupling member 642 and separates with first coupling member 641, second supporting member 62 can move up by the operation of first driver element 81.At this, under the state that the 3rd supporting member 63 stops, second supporting member 62 can move upward, till second coupling member 642 touches first coupling member 641 by moving upward of second supporting member 62.
Therefore, when nozzle 73 did not touch the upper surface of substrate S, laser displacement sensor 71 and nozzle 73 all can move up or down.When laser displacement sensor 71 stopped, nozzle 73 can move up or down.Further, when the upper surface that touches substrate S when nozzle 73 made that nozzle 73 stops, laser displacement sensor 71 can move up or down.Certainly, when when nozzle 73 is not side by side operated first driver element 81 and second driver element 82 under the state of the upper surface of contact substrate S, laser displacement sensor 71 can move up or down under the state that nozzle 73 stops, and perhaps laser displacement sensor 71 and nozzle 73 can side by side move in opposite direction.
Simultaneously, between second supporting member 62 and the 3rd supporting member 63, be provided with location measurement unit 90, to measure second supporting member 62 and the relative position of the 3rd supporting member 63 on Z-direction.Location measurement unit 90 can comprise reference cell 91 that is arranged on second supporting member 62 and the sensing part 92 that detects the position of reference cell 91 on Z-direction.This location measurement unit 90 is utilized the interaction between reference cell 91 and the sensing part 92, measures second supporting member 62 and the relative position of the 3rd supporting member 63 on Z-direction.
In the location measurement unit 90 of the example according to the present invention, reference cell 91 can comprise the measuring instrument with scale, and sensing part 92 can comprise the video camera of taking the scale image.In this case, can be based on the scale image measurement reference cell 91 of video camera shooting and the relative position between the sensing part 92.
In the location measurement unit 90 of another example according to the present invention, reference cell 91 can comprise that according to the different reflecting surfaces with different angles of reflection in position, sensing part 92 can comprise the optical receiving sensor of reception from the light of reflecting surface reflection.In this case, measure from additional source of light with from the light of reflecting surface reflection, thereby record relative position between reference cell 91 and the sensing part 92 by optical receiving sensor.
Simultaneously, according to the embodiment of the present invention, reference cell 91 is arranged on second supporting member 62, and sensing part 92 is arranged on the 3rd supporting member 63.Yet the present invention is not limited to this structure.That is to say that reference cell 91 can be arranged on the 3rd supporting member 63, and sensing part 92 can be arranged on second supporting member 62.
According to the relative position between second supporting member 62 and the 3rd supporting member 63, the relative position between reference cell 91 and the sensing part 92 changes thereupon.Suppose that the outlet and the laser displacement sensor 71 of nozzle 73 represented by reference letter N along the gap of Z-direction, gap between laser displacement sensor 71 and the substrate S is represented by reference letter L, and the gap between the outlet of nozzle 73 and the substrate S represented by reference letter G, then satisfies equation " G=L-N ".Referring to Fig. 3, a particular location of supposing reference cell 91 is denoted as O at zero point, and zero point nozzle 73 during the O place outlet and the gap between the laser displacement sensor 71 be denoted as NO, when the 3rd supporting member 63 moved up displacement H with respect to second supporting member 62, then obtain equation " N=NO-H ".Therefore, the clearance G between the outlet of nozzle 73 and the substrate S satisfies equation " G=L-(NO-H) ".Further, if the 3rd supporting member 63 moved down displacement H with respect to second supporting member 62, then obtain equation " N=NO+H ".Therefore the outlet and the clearance G between the substrate S of nozzle 73 satisfy equation " G=L-(NO+H) ".Like this, under the situation that changes relative position between laser displacement sensor 71 and the nozzle 73, measure in advance the zero point of location measurement unit 90 nozzle 73 during the O place outlet and the gap between the laser displacement sensor 71.Next, the nozzle 73 that utilization records by use location measuring unit 90 is with respect to the position of laser displacement sensor 71 and use laser displacement sensor 71 that laser displacement sensor 71 records and the gap between the substrate S, records the outlet of nozzle 73 and the clearance G between the substrate S.
Hereinafter the method that is used to control glue spreader according to of the present invention will be described.
As shown in Figure 4, when substrate S is positioned on the saddle 30, because the shape of the upper surface of the proper property of substrate S or saddle 30, so the height of the upper surface of substrate S is uneven and vertically changes.At this, when the substrate Building S was put on saddle 30, the height of the upper surface of substrate S can be the height of the upper surface of saddle 30 to the upper surface of substrate S.Alternatively, the height of the upper surface of substrate S can be the height of the upper surface from given reference point to substrate S.
When the height of the substrate S upper surface of measuring each part, as shown in Figure 4, the height that is positioned at the substrate S upper surface of various piece can be different with height change.If height a, b, c, d and the e of substrate S upper surface measure in regular place at interval indicates on substrate S measurement point A, B, C, D and E place, then can record the height change and the gradient of representing height change of the substrate S upper surface of each several part.For example, because the height of substrate S upper surface is reduced to height b from height a in part A B, therefore the height change of the substrate S upper surface in part A B equals b-a, and the gradient that expression substrate S upper level changes equals (b-a)/(B-A).Further, because the height of the substrate S upper surface in portion C D is increased to height d from height c, therefore the variation of the substrate S upper level in portion C D equals d-c, and the gradient that expression substrate S upper level changes equals (d-c)/(D-C).Like this, record the height of the substrate S upper surface in each part in a plurality of parts at regular interval, and utilized measured height to record the height change of the substrate S upper surface in the each several part.Referring to Fig. 4, the part that can see the height change minimum of substrate S upper surface is part A B, and the height change the best part of substrate S upper surface is portion C D.Further, as shown in Figure 4, can see, the gradient of the height change of the substrate S upper surface in the part A B, promptly formula (b-a)/(B-A) is expressed, is minimum, and the gradient of the height change of the substrate S upper surface in the portion C D, i.e. formula d-c)/(D-C) expressed, be maximum.With the method, can find the gradient the best part of the height change of substrate S upper surface by comparing the height change of the substrate S upper surface in the each several part.
The substrate S that is assumed to the coating fluid sealant and moves horizontally or the constant airspeed of nozzle 73, then compare substrate S upper level and change the vertical motion that to carry out nozzle 73 in the big part more quickly changing less part, to keep the gap between substrate S and the nozzle 73 even with substrate S upper level.
The method that is used to control glue spreader according to the present invention is controlled the vertical motion of nozzle 73 best according to the height change of substrate S upper surface.
With reference to Fig. 4 and Fig. 5 the method that is used to control glue spreader according to first embodiment of the invention is described.To be described in the first embodiment of the invention, and be used for controlling first driver element 81 and second driver element 82 with the method for moving nozzle 73 vertically based on the height of the substrate S upper surface of every part.
As shown in Figure 5, in the method that is used for controlling glue spreader according to first embodiment of the invention, at first, in step S11, measure the height that is seated in the substrate S upper surface on the saddle 30.
In order to measure the height of substrate S upper surface, can use the laser displacement sensor 71 that is installed to head unit 60.Except laser displacement sensor 71, also can use other machinery and electronic installation.
Can in substrate S entire upper surface scope, measure the height of substrate S upper surface.Alternatively, can be only---to be in the part that moves within it when discharging fluid sealants of nozzle 73---in the part of the substrate S of reality coating fluid sealant carry out the measurement to height.
But data Input Control Element about the measuring height of substrate S upper surface.Therefore, the control module utilization is controlled first driver element 81 and second driver element 82 about the data of the measuring height of substrate S upper surface.
When recording the height of substrate S upper surface, control module calculates the height change of the substrate S upper surface in the various piece and the gradient of height change based on the data about the measuring height of substrate S upper surface.The height change and the gradient of various piece are compared mutually, therefore should a plurality of parts be divided into two class parts, the absolute value of gradient of height change of promptly representing substrate S upper surface is less than default reference point (the less relatively part of the height change of the upper surface of substrate for example, for example the part A B of Fig. 4 or BC) part, with the absolute value of the gradient of the height change of expression substrate S upper surface part greater than default reference point (for example relatively large part of the height change of the upper surface of substrate, for example the portion C D of Fig. 4 or DE).In this regard, in step S12, the absolute value of the gradient of the height change of expression substrate S upper surface is set at the independent drive part (part A B and BC) that only drives first driver element 81 separately less than the part of default reference point, and will represent that the absolute value of gradient of the height change of substrate S upper surface is set at the driven in synchronism partly (portion C D and DE) that must drive first driver element 81 and second driver element 82 simultaneously greater than the part of default reference point.
In other words, even thereby the little vertical position of only adjusting nozzle 73 by first driver element 81 of the gradient of the height change of substrate S upper surface also can keep the uniform part in gap between substrate S and the nozzle 73, is set at the independent drive part A that only drives first driver element 81 separately.Simultaneously, thereby the gradient of the height change of substrate S upper surface is difficult to keep the uniform part in gap between substrate S and the nozzle 73 greatly under the vertical position situation of only being adjusted nozzles 73 by first driver element 81, be set at the driven in synchronism part B1 and the B2 that drive first driver element 81 and second driver element 82 simultaneously.
As mentioned above, after having set independent drive part (part A B or BC) and driven in synchronism part (portion C D or DE), nozzle 73 moves to the coating starting point SP on the substrate S, and begins to discharge fluid sealant thus.In step S13, when nozzle 73 along continuous straight runs move, only driving first driver element 81 to adjust the vertical position of nozzle 73 in the drive part separately, and in driven in synchronism part, drive first driver element 81 and second driver element 82 simultaneously adjusting the vertical position of nozzle 73, and fluid sealant is coated on the substrate S.
The method that is used to control glue spreader according to first embodiment of the invention is as follows: measuring seat places the height of the upper surface of the substrate S on the saddle 30; Based on the measuring height of substrate S upper surface, the fluid sealant coated portion is divided into the independent drive part that only drives first driver element 81 and drives first driver element 81 simultaneously and the driven in synchronism part of second driver element 82; And carry out the fluid sealant coating and operate.Therefore, in the method that is used for controlling glue spreader according to first embodiment of the invention, to such an extent as to it is too big only by driving in the part that first driver element 81 can not keep the uniform gap between substrate S and the nozzle 73 in the gradient of the height change of expression substrate S upper surface, drive first driver element 81 and second driver element 82 simultaneously, therefore in whole fluid sealant coated portion, keep the gap between substrate S and the nozzle 73 even.
Hereinafter the method that is used to control glue spreader according to second embodiment of the invention is described with reference to Fig. 6 and Fig. 7.According to second embodiment of the invention, set nozzle 73 at the coating starting point place of beginning fluid sealant coating operation the initial position IP of (Z-direction) vertically, with the bigger part of height change of treatment substrate S upper surface suitably.
As shown in Figure 6, according to second embodiment of the invention, at first, at step S21, measuring seat places the height of the substrate S upper surface on the saddle 30.At this, can in substrate S entire upper surface scope, measure the height of substrate S upper surface.Alternatively, can be only in the part of the substrate S of reality coating fluid sealant, carry out measurement to height.
At step S22, behind the height of having measured substrate S upper surface, control module calculates the average height M of substrate S upper surface.
Further,, utilize the average height M of substrate S upper surface, set nozzle 73 begins fluid sealant coating operation on substrate S the initial position IP vertically of coating starting point SP place at step S23.
At step S24, nozzle 73 is positioned to be set in the initial position IP place at coating starting point SP place, and fluid sealant is applied on the substrate S, adjusts the position of nozzle 73 with respect to substrate S simultaneously.
As mentioned above, it is as follows to be used to control the method for glue spreader according to second embodiment of the invention: measuring seat places the height of the upper surface of the substrate S on the saddle 30; Calculate the mean value M of the measuring height of substrate S upper surface; And the calculating mean value M that utilizes the height of substrate S upper surface, set nozzle 73 and be coated with the initial position IP of (Z-direction) vertically of starting point SP place, therefore in whole fluid sealant coated portion scope, keep the gap between substrate S and the nozzle 73 even, thus the height change of treatment substrate S upper surface.
The technical spirit content of embodiment of the present invention can be implemented or be bonded to each other independently of one another.That is to say, another embodiment according to the present invention, the method that is used for controlling glue spreader is as follows: as second embodiment, set the nozzle 73 initial position IP of (Z-direction) vertically; Nozzle 73 is placed initial position IP place; And, partly drive first driver element 81 and/or second driver element 82 according to independent drive part or driven in synchronism as in first embodiment, therefore adjust nozzle 73 position vertically.
