BRIEF DESCRIPTION OF THE DRAWINGS [Technical Field] The present invention relates to a sealant dispenser which can dispense a sealant onto a glass in a prescribed pattern or shape when manufactured in a planar manner. More specifically, the present invention relates to a method of calibrating a rack in a sealant dispenser by which an accurate dispensing operation can be performed. [Prior Art] A liquid crystal display (LCD) is a type of flat display device, a phase cathode ray tube (CRT), which has a better visual quality. In addition, the average power consumption will be less than the power consumption of the CRT with the same screen size, and the LCD will generate less heat than the CRT. LCD and plasma display panels (PDPs) or field emission displays (FEDs) are the next generation of display devices for mobile phones, computer screens and televisions. The LCD is manufactured by forming a complex pattern or a thin film planar transistor (TFT) on a first glass substrate, and forming a color filter layer on the second glass substrate on the opposite side of the first glass substrate, and The liquid crystal is applied to any of the glass substrates, and then the first and second glass substrates are combined. During the manufacturing process of the LCD, the sealant dispenser is dispensed onto the glass substrate according to a specified pattern of sealant. In general, when performing such a dispensing operation, the sealant dispenser re-adjusts the sub-head (for example, in the forward and backward directions) or from side to side (ie, lateral direction) (its The position at which the sealant is dispensed, at which point the glass substrate is fixed. The display substrate support is averaged compared to the LCD, and is viewed as a picture board. The dispenser that is to be retracted is solid 5 1324267

The perspective view of Figure 1 illustrates a method of calibrating a support frame in a sealant dispenser application sealant dispenser. Figure 2 is a plan view of a conventional sealant dispenser showing the problems associated with the sealant dispensing process. The structure of the conventional sealant dispenser and the problems of the conventional detergent dispenser will be described below with reference to Figs. 1 and 2. Referring to Figures 1 and 2, a sealant dispenser for manufacturing a large-sized liquid crystal panel includes: a frame 10 representing a main body of the adapter; and a platform 20 disposed on a top surface of the frame 10 24, erected on the platform 20 to accommodate a glass substrate 50 and a sealant 5 2 is distributed on the glass substrate 50; and a first linearity 22 for the front-back direction of the frame 10 or parallel to The seat 24 is driven in the direction of the S-axis.

The first sealing agent distributor further includes a plurality of linear motor guiding members 35 disposed on opposite ends of the platform 20, along the frame. a forward and a back extension of 10; a first support frame 31 and a second support frame 32 disposed between the linear motor guides 35 and simultaneously disposed perpendicular to the longer side of the frame to The first support frame 3 1 and the second support frame 3 2 are moved along the equal linear motor guides 35; and at least one second linear motor 3 3 is used to drive the support frames 3 1 and 3 2 A plurality of wire motor guides 35 move along the frame 10. Recently, the size of the glass substrate 50 has gradually increased. In order to compensate for such an increase, at least two support frames (i.e., the first support 31 and the second support frame 32) are generally provided to shorten the time of the dispensing process. Here, a second linear motor 33 is respectively mounted on the opposite ends of the first support frame 31 and the two support frames 32. 6 1324267 A plurality of head units 41 are provided on one side of each of the first support frame 31 and the second support frame 32. The head units 41 are moved in a first direction (parallel to the direction of the Q axis or parallel to the longer sides of the support frames 31 and 32 or perpendicular to the direction of the linear motor guides 35). The sealant 52 is dispensed in a particular pattern or shape. The sealant 52 is dispensed onto the glass substrate 50 that is fixed to the seat 24. In addition, a third linear motor 44 is disposed to drive the head units 41° in the first direction.

In detail, each head unit 41 includes a head chassis 43, and when the driving force of the third linear motor 44 is transmitted to the head chassis 43, each head unit 41 is in the first direction ( Move parallel to the direction of the Q axis). Further, a syringe (not shown) attached to the head chassis 43 is provided to accommodate the sealant 52. In addition, the platform 20 is erected such that the platform 20 can be in a second direction (ie, parallel to the direction of the S-axis or parallel to the direction of the linear motor guides 35 or perpendicular to the support frames) The directions of 31 and 32) are moved by a predetermined angle to align the glass substrate 50 fixed to the stage 24.

The sealant dispenser for the operation of the above structure will now be described in detail. First, the glass substrate 50 is fixed above the seat 24 by suction, and the seat 24 is fixed to the platform 20»Rectangle and has a pattern (for example, a circular pattern 53) formed thereon in advance. The glass substrate 50 will be fixed to the stage 24 while being aligned with the frame 10. The dispensing operation of the sealant is then carried out. There are generally two methods of dispensing the sealant 7 1324267 to the glass substrate 50. The first allocation method is as follows. The first support frame 31 and the second support frame 32 are moved in a first direction (the direction is parallel to the linear motor guide 35 of the frame 10), and the heads are mounted on the support frames 31 and 32. The unit unit 41 is moved in a second direction (the direction is perpendicular to the linear motor guide 35 of the frame 1) to distribute the sealant on the glass substrate 50.

This second allocation method is as follows. The platform 20 is moved in the first direction, and the head units mounted on the support frames 31 and 32 are moved in the second direction to distribute the sealant on the glass substrate 50. That is, the sealant is dispensed on the glass substrate 50, and the stage 20 and the head units 41 move relative to each other. This second method is mainly used for a large-sized glass substrate 50. More specifically, when the large-sized glass substrate 50 is placed in the sealant dispenser, the two support frames 31 and 32 are in the second direction (along the front and rear directions of the linear motor guide 35). Move to ensure that there is enough space to place or remove the glass substrate 50. Thereafter, the glass substrate 50 is fixed to the stage 24. However, the above-described conventional method of dispensing a sealant has the following problems.

Due to process errors, the first support frame 31 and/or the second support frame 32 disposed between the linear motor guides 35 may not be parallel to the Q axis and/or may not be parallel to each other. In addition, proper alignment may not be possible when the glass substrate is fixed to the stage. Therefore, the first support frame and/or the second support frame cannot be parallel to the Q axis and/or parallel to each other. If the correction of the alignment deviation of the support frame cannot be completed before the dispensing operation is performed, the head units moving along the support frame that are aligned with the deviation are not assigned the seal according to the preset display pattern without the 8 1324267 method. Agent. As a result, unaligned support frames will add many defective products and increase manufacturing costs. SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a method of correcting the position of a support frame in a sealant dispenser that substantially solves many of the problems caused by the limitations and disadvantages of the related art.

It is to be understood that the foregoing general description of the invention, DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments embodiments Wherever possible, the same reference numerals are used for the same or similar parts. A method of calibrating a support for dispensing a sealant in accordance with the present invention will now be described with reference to the following figures. As shown in FIG. 1, a sealant dispenser for applying a method of calibrating a sealant dispenser according to the present invention comprises a frame 10, the dispenser body, and a platform 20 disposed on the frame 10. a table 24 is mounted on the platform 20 to accommodate a glass substrate 50 on the glass substrate and is provided with a sealant, and the glass substrate 50 is placed on the upper surface of the seat 24; and a first linear motor 2 2. The second stage is used to drive the stage 24 in a second direction. Here, the second direction is parallel to the direction of pumping. Several equal line supports along the brackets and steps

The sealant distributor is further provided with a plurality of linear motor guides 35, which are disposed on the opposite side of the platform 20 in the second direction, according to the S 11 1324267. end. In addition, the sealant dispenser includes a first support frame 31 and a second support frame 32 disposed between the linear motor guides 35 while being configured to move in the first direction so that The first support frame 3 1 and the second support frame 3 2 are movable along the linear motor guides 35, and at least a second linear motor 33 for driving the support frames 31 and 3 2 moves along the linear motor guides 35 (ie, in the second direction).

The plurality of second linear motors of the sealant distributor include a plurality of second magnets 3 3 disposed on the upper surface of each of the linear motor guides 35 and the plurality of second moving members 34 in the second direction. They are disposed at the lower ends of the opposite sides of the respective support frames to correspond to the second magnets 3 3 .

Here, since the size of the glass substrate 50 is large, and in order to reduce the time of the dispensing operation, the sealant dispenser includes two support frames, that is, the first support frame 31 and the second support frame 32. However, the number of support frames is not limited, and more support frames can be provided as needed. In addition, a plurality of second moving members 34 of the second linear motors are mounted on opposite ends of the individual support frames 3 1 and 32 to provide driving force to the opposite ends of the support frames 31 and 32. A plurality of head units 4 1 are disposed on one side of each of the support frames 3 1 and 3 2 to allow the head units 41 to move in the first direction (parallel to the direction of the Q axis), so the heads The unit unit 41 can perform a dispensing operation on the glass substrate (fixed to the stage 24) according to a predetermined pattern (or shape). In addition, the sealant dispenser further includes a third linear motor for driving 12 1324267 the head units 4 1 to move in the first direction. More specifically, each of the head units 41 disposed on the support frames 31 and 32 includes a head bracket 42 that can be used when the driving force of the third linear motor is supplied to the head bracket 42. Moving in a first direction; a syringe (not shown) coupled to the head carrier 42 for receiving a sealant; and a nozzle (not shown) for dispensing the sealant by the syringe.

In addition, the third linear motor of the sealant distributor includes a plurality of third magnets 44 disposed on one side of each of the support frames 31 and 32 in the first direction, and a plurality of third moving members 43 disposed In each of the head brackets 42 corresponding to the third magnets 44.

The sealant dispenser further includes a plurality of alignment sensors 45 that move in a first direction to identify a plurality of correction marks 55. The correction marks 55 are disposed on (or printed on) the glass substrate 50 in advance (for example, when the glass substrate is formed), or are marked after the glass substrate 50 is manufactured. Preferably, the alignment sensors 45 are coupled to the head units 41 for movement in the first direction by operation of the third magnets 44 and the third moving members 43. The correction marks 55 are provided on the edges of the circuit patterns 53 formed on the glass substrate 50 as a reference for measuring the alignment of the support frames 31 and 32 to the glass substrate 50. The straight lines connecting the correction marks 55 are parallel to each other or perpendicular to each other. The combination of the third moving member 43 and the third magnets 44 allows the head units 41 to move in the first direction, and the alignment sensors 45 can move together with the head units 41 as a whole. The correction marks 55 provided on the glass substrate 50 are sequentially identified. 13 1324267 A calibration method of the support frame having the above structure will now be described. The flowchart of Figure 3 illustrates a method of adjusting the alignment (or position) of the support frame in the sealant dispenser in accordance with a preferred embodiment of the present invention. The reference drawing of Figure 4 illustrates two non-parallel support frames and alignment sensors mounted on the second support frame for movement along the Q axis to identify the correction marks.

First, the glass substrate 50 is mounted on the stage 24, and then appropriately fixed thereto. After the glass substrate 50 is fixed to the seat 24, the support frames 31 and 32 move toward the print correction marks 55 on the glass substrate 50 (S1). Thereafter, the second support frame 32 is moved to a position by which the support frame is calibrated. After the second support frame 32 is placed in the calibration position, the third linear motors drive the head unit 41 coupled to the second support frame 32 to perform the identification operation of the correction mark. More specifically, the identification mark recognition operation includes a plurality of alignment sensors 45 coupled to the head units 41 to follow the first direction or along the support frame 32 (S) 2) While the longer side direction is moving, the correction marks 55 indicated on the glass substrate 50 are identified.

Next, the imaginary line connecting the correction marks 55 can be recognized by the alignment sensors 45. The imaginary straight line is compared with one of the paths of the alignment sensors 45 to determine whether the imaginary line and the path are parallel to each other (S3). Hereinafter, the imaginary line is referred to as an X1 line 150. The X 1 line 1 50 is parallel to the S axis. In addition, the path of travel of the alignment sensors 45 along the support frames 3 1 and 32 will be referred to as the X2 line 160. The X2 line 14 1324267 160 is parallel to the Q axis. As shown in FIG. 5, when the X2 line 160 and the XI line 150 are not parallel to each other, calibration is performed by aligning the X2 line 160 and the XI line 150 so that the two lines are parallel (S4). The alignment of the X2 line 160 with the XI line 150 is corrected.

When performing the calibration (S4), a control unit calculates the offset of the X2 line 1 60 to the X 1 line 150. The offset is measured here by angle. Thereafter, the control unit calculates an offset required to correct the alignment deviation of the X2 line 1 60 such that the X2 line 160 is adjustable to be parallel to the XI line 150. At the time of calibration, the control unit uses the corrected offset to adjust the second moving member 34 disposed on the support frame 32 such that the X2 line 160 is parallel to the XI line 150.

Preferably, a plurality of second moving members 34 are disposed on at least two sides of the support frame 32. Here, the second moving member 34 disposed at the end of the support frame 32 will remain fixed, and the second moving member 34 disposed at the other end of the support frame 32 will follow the corresponding second linear motor guide member 35. The second direction (along the advancement path of the linear motor guide 35) is moved such that the X2 line 160 is preferably parallel to the X1 line 150. If it is determined in the step (S3) that the X2 line 160 is parallel to the XI line 150, the calibration operation of the support frame of the step (3) can be terminated without continuing the step (S 4). When the alignment process is completed, the second support frame 32 becomes parallel to the XI line 150, so that the second support frame 32 is aligned with the circuit patterns 53. At the same time, the above alignment procedure can be applied to the first and second diagrams. After the 15 seals, the 32 seals can be used to determine the sealant distribution of the single support frame or at least two support frames. Device. If the adhesive dispenser comprises at least two support frames as described above, the alignment of the support frame preferably includes a confirmation step (s 5) to determine whether the respective shooters performing the alignment operation have been properly quasi. In the confirmation step (S5), whether or not the alignment processing steps (S1_S4) of the respective support frames 31 and are performed are performed, a judgment is made after the completion of the step (S4). If all the alignment steps of the support frames 31 and 32 have been performed, the calibration of the support frames may be further terminated. If the complete alignment procedure has not been performed on a support frame, the support frame may be repeatedly executed. The school steps (S1-S4). If the sealant dispenser includes at least two support frames, and when the calibration is not fully performed on the two to two support frames, calibration of at least one of the at least two supports may be performed first in the support frame After the calibration, calibrate the next yoke. That is, the trusses will be calibrated sequentially. The calibration of the at least two supports can be performed simultaneously. In the above embodiments, the subracks are aligned based on correction marks provided on the glass sheet. However, in other embodiments, the offset angle of the glass substrate (measured by angle) is also rotated to calibrate the support such that the plurality of support frames are in contact with each other... Here, the offset angle table of the glass substrate must How many angles can be pseudo-shifted parallel to at least two flat support frames. Referring to other embodiments, the sealant dispenser comprises: a frame representing the body of the dispenser; a platform disposed on the upper surface of the frame; and a platform mounted on the platform 20 to accommodate a glass substrate, And the sealing 16 1324267 agent is distributed on the glass substrate, and the glass substrate is placed on the upper surface of the platform; a plurality of linear motor guiding members are disposed on opposite sides of the platform, so that the The linear motor guide extends along the s-axis; at least two support frames are perpendicular to the linear motor guides and disposed between the linear motor guides, so the at least two support frames can be along The linear motor guides are moved in the second direction; and a distance measuring unit for measuring at least two distances between the at least two support frames.

In addition, the calibration method of at least two support frames in the sealant dispenser includes: measuring at least two distances between at least two support frames, calculating a difference between the measured distances, and calibrating the support by applying the calculated difference The racks are such that the measured distances are equal by the parallel distance of the at least two doses, and the glass substrate is rotated to align the glass substrate to the at least two support frames. A more detailed description of other embodiments of the invention will be described with reference to the accompanying drawings. Since the parts of this embodiment are identical to the previous embodiment, it will not be described in detail.

The example of Figure 5 illustrates a glass substrate mounted on a sealant dispenser having a support frame that has not been aligned. Figure 6 shows the calibrated support frame of Figure 5; however, the glass substrate and the support are in misalignment (or non-parallel). Figure 7 shows the alignment of the glass substrate of Figure 6 with respect to the support frames. The flowchart of Figure 8 illustrates the calibration method of the support frame in the sealant dispenser. In this embodiment, the sealant dispenser includes a frame 1 (see Figure 1), a platform 20 (see Figure 1), a table 24 (see Figure 1), and at least 17 1324267. 3 1 and 3 2, which are movable along a plurality of linear motor guides 35. More specifically, the platform 20 can be configured to rotate to its left or right side. For example, the platform can be rotated 2 degrees to the left to align the glass substrates placed at the top of the platform with the support frames.

The sealant dispenser further includes a distance measuring unit for measuring at least one distance between the two support frames 31 and 32. Preferably, the distance measuring unit measures at least two linear distances d 1 and d2 between the support frames 3 1 and 3 2 . For example, the at least two distances should be approximated or at the terminal end of the support frame, close to the linear motor guides 35°. The distance measuring unit comprises two displacement sensors 140, which are erected on One of the support frames 31 or 32. Preferably, the laser displacement sensors should be non-contact. As depicted in Fig. 6, the laser displacement sensors 140 are positioned adjacent to the terminal portions of the support frames 3 1 or 3 2 to perform accurate measurements. Here, the laser displacement sensors 140 can measure the linear distances d 1 and d2 between the support frames 3 1 and 3 2 .

A method of calibrating the support frame in the sealant dispenser of the above construction will now be described in detail with reference to Figs. 5 to 8. In the following description, we assume that the two support frames 31 and 32 are not parallel to each other, and the glass substrate 50 placed in the table 24 is initially misaligned with the support frames 31 and 32 and the frame 10. First, after performing the measuring step (S'1), the glass substrate 50 is placed in the stage 24. The measuring step (S ' 1 ) measures the distances d 1 and d 2 between the opposing support frames 3 1 and 3 2 18 1324267 using a laser displacement sensor 140 mounted on the support frame 3 1 . Then execute - the setting step (S, 2). The determining step (S, 2) calculates the difference between the distances d1 and d2 between the support frames 31 and 32 measured in the measuring step (S'1). If it is determined that the distance dl is equal to the distance d2 (ie, there is no difference between the equal distances d1 and d2 'representing the two support frames 31 and 32 are flat with each other)', a substrate alignment step (S, 4) is performed. ). However, if the distance is determined to be not equal to the distance d2 in the decision lock (S 2) (ie, there is a difference between the distances di and d2, it means that the two support frames 31 and 32 are not parallel to each other) , a support alignment step (s, 3) is performed. The support frames 31 and 32 are calibrated in the support alignment step (s'3), as shown in Fig. 6 such that the distances d丨 and d2 are calculated according to the determination step (S'2). The difference between dl and d2 has the same value. Thus, the branches 31 and 32 are parallel to each other. After the support frames 31 and 32 are fully aligned, this procedure preferably returns to the measuring step (S, l) to measure the equidistances dl and d2. Thereafter, the decision step C §, 2, 4, 丨 ** outside 0 2) is performed to determine whether the distances d1 and d2 are the same. When the 卞^ and 32 are calibrated, one of the support frames 31 and 32 is preferably maintained fixed or stationary (ie, the support frame 32), and the support frame (ie, the support frame 31) is fixed according to the fixed The support frame (i.e., support frame 32) is used to make the necessary adjustments. At the time of adjustment, one end of the β-support frame 3 1 will move along the corresponding linear motor guide member 35, and 兮* ρ年3〗 while the other end of the s-frame truss 3 1 is fixed or not The linear motor guide 35 is moved. 19 The following will be discussed in the first place. Preferably, the supports in the frames 31 and 32 are supported by τ &lt; - those are fixed (ie, the support frame 32), and the calibration operation is performed as a reference, while another support The frame 3 1 is moved along the starting guide 35 to mount the mounting frame to align the other end portions, for example, for the reference branch The terminal portion of the support frame 31 of the distance di and υ distance is based on the distance (reconciled in S'2), and is moved away from the reference support frame 32 to achieve The parallel state between the support frames 31 and 32. Alternatively, the terminal portions of the support frame 3 1 having a longer distance from the center of the circle and d2 may be parallel to each other in such a manner that the support frames 31 and 32 are moved in the direction toward the support frame 32 in accordance with the distance difference '. ^ or the terminal portions of the support frames 31 and 32 may be moved in opposite directions to make the -the first support frame (ie, the support frame 31) parallel to the second support frame (ie, the 'support frame 32), or Both of the support jaws 31 and 32 are moved to adjust the distance between the support frames to achieve a parallel state. In the substrate alignment step (S'4), the glass substrate 50 is rotated by a specific angle β' such that the circuit pattern 53 of the glass substrate 5 is parallel to the S-axis of the support frames 31 and 32. Preferably, the platform 20 is also rotated a particular angle, and thus the platform 20 should be rotated to cause a corresponding rotation of the glass substrate 50 secured to the table 24. Here, the two support frames 31 and 32 are parallel to each other, and therefore, when the glass substrate 50 is rotated such that the glass substrate 50 is parallel to the support frames 31 and 32, the two support frames 31 and 32 can be achieved. Alignment between the glass substrates 50. As shown in Fig. 7, the sealant 52 can be accurately dispensed on the glass substrate 50 if the support frames 31 and 32 are parallel to each other 20 1324267. It will be appreciated by those skilled in the art that various modifications and changes can be made in the present invention without departing from the spirit and scope of the invention. Therefore, the invention is also intended to cover the modifications and modifications of the scope of the appended claims. [Simple description of the map]
