The present invention relates to a single-tension welding device for manufacturing AMOLED movable mask frame elements and a method for manufacturing AMOLED movable mask frame elements using the device. More specifically, it relates to a method for manufacturing a mask frame element mounted on The frame is air floated to accurately center and align (align), reduce vibration when welding the split mask on the frame, improve the measurement accuracy and welding accuracy, and the manufacturing method of the mask frame component using the device.

Recently, organic light-emitting diodes (OLEDs) have attracted attention as display elements for various purposes. Their response speed is much faster than thin-film transistor liquid crystal displays (TFT LCDs), and they can be used without a separate backlight. It is self-luminous, and has a simpler structure and fewer components than LCDs, which can greatly reduce the thickness and weight of LCDs during manufacturing. It has a wide viewing angle and low power consumption structure, so it is the next generation display device.

The OLED is divided into active mode (AM) and manual mode (PM). In particular, each pixel of AMOLED has TFT and capacitance, and is excellent in power consumption, lifetime and resolution. Therefore, it overcomes the shortcoming of high manufacturing cost in the manufacture of TFT, and is trying to actively develop and Mass production.

In particular, AMOLEDs have recently been used as display elements in various fields, among which the most representative fields are large display devices such as TVs and small display devices such as smart phones. especially Yes, the smart phone field is an area where new products are launched every year and the user's replacement demand is also active, so its business prospects are very bright.

However, in the field of small-size display such as smart phones, in order to provide various multimedia environments required by users, the demand for high-resolution display panels is increasing. Therefore, it is very important to ensure the manufacturing technology of accurate mask frame elements.

A brief description of the existing manufacturing method of the mask frame element using the split mask is as follows: the loading frame is placed at the centering position of the reference point by means of a conveyor and a lifting platform, and then the split mask grabbed by the gripper is transported to The working position is aligned and clamped, and then the segmented mask image is captured based on the mother glass under the segmented mask to detect the pixel position accuracy (PPA), if the detected segmented mask shape information is within the tolerance of the PPA Within the range, the segmented mask is welded and fixed to the frame, and then the new segmented mask is repeatedly inspected, corrected, and welded in the same method to manufacture the mask frame component.

However, in the manufacturing process of the existing mask frame components as described above, the process of loading the frame and aligning the reference and centering is the most important process that determines the output of the mask frame components, while the existing frame manufacturing process has different manufacturing processes. Precise structural issues.

Specifically, in order to load and align the frame to the centering position, the prior art uses a ball float method, and uses a cylinder to align the centering position with the lower part of the frame supported by the ball to align the frame to the reaction force position. This method has a problem that the frame cannot be aligned to a precise position.

That is, when using cylinders to move the long or short sides of the frame, it is difficult to control the position with precise values using hydraulic or pneumatic cylinder operation. Even if the centering position of the frame is accurately aligned during measurement, if it is in contact with and supported When the ball float at the lower part of the frame is lowered to apply an impact, a slight change is required. However, in the case of a slight position change, it is impossible to maintain high quality as an accurate mask frame element that requires an error in micrometers. problem.

In addition, in the prior art, after the frame is centered, a grabber is used to load the split mask and then the position is aligned, and then during welding, inspections for detecting the welding position and confirming the welding state after welding are performed to ensure the welding position and Welding quality, at this time, if it is to achieve accurate measurement, it is difficult to guarantee high-quality mask frame components.

This is because the double-headed detection and welding device used in the prior art to detect the welding quality between the frame and the split mask is generally composed of two welding devices suspended on one transfer platform, and the two welding devices are A welding device in the device is also provided with a welding quality detection device. Correct The double-headed welding and inspection device with this structure has the following specific problems: the welding device is equipped with a welding quality inspection device for confirming the welding quality after welding the split mask, and the welding device moves on the gantry to produce a small amount of The change in the center of gravity of the weight also generates vibration, so the accuracy of the detection can be reduced.

Therefore, the reality is that the necessity of an AMOLED mobile mask frame element manufacturing device that solves this existing problem is increasing.

Hereinafter, the structure and function of the embodiment of the present invention will be described in detail below with reference to the drawings. In addition, when describing the present invention, if it is judged that the detailed description of the related well-known function or structure unnecessarily makes the main point of the present invention unclear, the detailed description will be omitted.

Fig. 1 is a perspective view showing the overall structure of a single tension welding device according to an embodiment of the present invention.

As shown in the figure, the single-tension welding device for manufacturing mask frame elements of the present invention includes: a frame position aligning part 1 for installing the loaded frame 5 in a state of being air-floated by the air-floating part 110, and then using the frame The position adjustment part 120 is aligned with the reference centering position to provide an opposing force (tension is applied); the three-head welding and detection part 2 is clamped on the cover by the clamping part 3 in a single tension method on the upper part of the precisely placed frame The divided masks selected from the divided masks 6 in the frame portion 4 are mounted on the welding position, and after the welding position is aligned with the vibration reduced, the welding is performed, and the welding quality of the welding is inspected.

The single-tension welding device with the frame position alignment part 1 described above is used to accurately adjust the position of each frame position adjustment part 120 in the state of air-floating the frame 5 when manufacturing the AMOLED movable mask frame element. The position adjusting part 120 is arranged to face each other with the short side and the long side of the frame, and then the air floating part 110 is used to release the air floating state, and then the frame is accurately adjusted within the range of the centering position reference 5 μm. At this time, the frame position alignment part has an alignment function that integrates the frame and the camera axis after the frame is centered, and it also takes into account the resistance to the deformation of the frame when the mask is welded after the alignment is provided with tension. Force acting device.

In addition, the air-floating portion 110 is composed of the air-floating portion 110 that independently divides the regions corresponding to the short sides and the long sides of the frame when the frame 5 is air-floated, so uniform and independent spray air is stably supplied to the short sides and The lower surface of the long side can stably eliminate air flotation. If air flotation is eliminated, the frame accurately aligned in the air-floated state is placed on the platform without impact to achieve precise centering alignment.

In addition, a single-tension welding device with a three-head welding and detection unit 2 uses the clamp of the clamping unit 3 to clamp the divided mask 6 loaded on the mask frame portion 4 in a single-tension mode, and then load it into The upper part of the frame 5 is aligned with the welding position, and then the two welder parts 210 and 220 suspended on the gantry 20 are used to weld the frame and the split mask, and then the welding inspection part 230 located in the center is used to detect the welding quality. The two welder parts 210 and 220 suspended on the gantry play a role in balancing the weight. Then, while the weight balance of the gantry is adjusted in a balanced manner, only the welding tester part 230 moves on the gantry for inspection, and no Sudden weight changes will occur, thereby achieving accurate detection while suppressing vibration.

In addition, the single-tension welding device with three-head welding and detection unit 2 is used to make AMOLED movable mask frame components. The two welder parts 210 and 220 composed of three-heads on the stand 20 are not only balanced The weight is used to make the welder move independently and accurately in the welding track formed in the same axial direction as the moving direction of the gantry while the gantry is stagnant during welding, so that vibration does not occur when the gantry moves. Realize precise detection and welding of welding position.

The clamping part 3 is a tool for clamping and transporting the divided mask usually used in the mask frame element device. A pair of the clamping parts 3 are provided to respectively follow the two clamps formed in the single-tension welding device. The conveying rail moves; the clamping parts on each side clamp the two side ends of any divided mask loaded on the mask frame part with respective clampers, and convey it to the welding position on the aligned frame. In addition, the clamping part is provided with a hydraulic or pneumatic application tool and a servo motor that provides a clamping force for clamping the split mask, and the servo motor advances and retreats the clamp to apply precise tension. The detailed structure of the clamping part is a structure well-known in this field, so the detailed description is abbreviate|omitted.

The mask frame part is a tool for loading multiple divided masks arranged in multiples, which can shorten the process time required when manufacturing mask frame elements. The upper and lower multi-layer structure is composed of multiple divided masks on each layer. And supply the carrier in turn. In more detail, the structure of the mask frame is not the core structure of the present invention, but is a structure provided with a well-known general mask frame, so the detailed description is omitted.

Hereinafter, the frame alignment part 1 and the three-head welding and detection part 2 of the present invention will be described in detail.

2 is a diagram showing an example of a frame position aligning part having air holes in which regions are divided according to an embodiment of the present invention; FIG. 3 is a diagram showing an individual gas hood placed in the frame position aligning part of an embodiment of the present invention 3D perspective view; Figure 4 is a rear view showing the individual gas hoods installed in the frame position alignment portion of an embodiment of the present invention; Figure 5 is a diagram showing the position of the frame in which the individual gas hoods are installed in an embodiment of the present invention Fig. 6 is an exemplary diagram showing a state in which the frame is loaded and aligned with the frame by the frame position alignment part of an embodiment of the present invention.

The frame position alignment part 1 of the present invention roughly includes: an air-floating part 110 that lowers the loaded frame to a predetermined height; a frame position adjusting part 120 that accurately adjusts the position of the air-floating frame according to a reference; The frame is placed on the upper part of the frame position alignment part 1, and the frame lifting part 130 is lifted and lowered after the frame is welded and divided.

First, the air floating part 110 is composed of a plurality of air hole parts 111 and a plurality of air cover parts 112 provided on the upper part of the air hole part. If the frame lifting part 130 is lowered after loading the frame, the air float part 110 sprays air to keep the frame in a balanced floating state. In such a floating state, if the frame position adjusting portion 120 is accurately aligned with the centering position, the air supply to the air-floated frame is gradually released, and the aligned state is maintained and placed on the upper surface of the air cover portion 112 .

The air hole 111 receives compressed air through an air compression line connected to an unshown air compressor, and then injects the compressed air. In particular, the air hole 111 is composed of a protruding support frame 111a and a plurality of protruding support frames. Two air holes 111b are formed, and the air chamber 112a formed at the lower part of the hood 112 placed on the upper part of the air hole 111 is inserted into the protruding support frame 111a to be supported, and air is supplied to the inner space of the air chamber through the air holes unit.

In addition, the air hole 111 has a plurality of independent structures and supplies compressed air to individual frames. That is, each side of the frame of a single right-angled quadrilateral structure composed of short sides and long sides corresponds to the air hole portion to supply compressed air. Preferably, each short side of the frame has one air hole, and each long side of the frame corresponds to two air holes to supply compressed air.

As mentioned above, the reason for having a plurality of air holes in which the air injection area is divided independently is as follows: If a single air hole is formed of a structure divided into four parts, the compressed air cannot be uniformly supplied to the lower part of the frame. If compressed air is supplied from the side, stable and uniform air floatation cannot be achieved, and it is difficult to provide precise centering and alignment when the frame is inclined to one side.

The upper part of the hood portion 112 is processed into a flat shape, and an air chamber 112a is formed in the inner side direction of the lower surface, and the air chamber 112a is a groove into which the protruding support frame 111a can be inserted. In the air chamber 112a, air supplied through the air holes 111b of the protruding support frame 111a inserted into the inner space is sprayed on the lower surface of the frame 5 at a uniform pressure through a plurality of air holes 112b penetrating the upper part of the air chamber 112a. In addition, the hood 112 is provided with two on the long side. The air holes 111b of the support 111a receive uniform compressed air so that the air is evenly sprayed on the lower surface of the frame 5 located on the long side.

As described above, the reason for configuring the plurality of air hood portions 112 with air chambers 112a in the lower part and the two air chambers in the lower part of the long side air hood is as follows: the received air is uniformly filled in the air chamber. After that, it is supplied to the lower part of the frame with uniform pressure through the air holes, and then the frame is air-floated with a uniform height to achieve precise centering.

On the other hand, a support groove 113 is formed on the outer side of the hood portion on the long side, and the lower surface of the frame is supported by the frame lifting portion 130 to rise or fall.

The frame position adjusting portion 120 constitutes a position adjuster 121 on the short side and the long side, and the position adjuster 121 is composed of a servo motor 122 and a contact portion 123. According to an embodiment, it is preferable to form two position adjusters 121 on each short side and three position adjusters 121 on each long side. With this configuration, the position adjusters located on the short and short sides facing each other and the long and long sides facing each other accurately advance and retreat to adjust so that the contact portions 123 contact each of the air-floating frame. Position the centering position in the side state. Such a position adjuster is aligned with the centering position of the frame within 5 μm based on the centering position reference.

In the prior art, an air cylinder is used to center the frame, but the air cylinder cannot advance and retreat to a precise position, and it is difficult to accurately adjust the position of the frame, and thus it is impossible to accurately position the mask on the frame in a μm unit level. It cannot be soldered, so there is a problem that the quality of the AMOLED panel manufactured by manufacturing the mask frame element is reduced. However, the mobile AMOLED panel manufactured by using the mask frame element of the prior art has a low-resolution screen. Although the slight difference does not have a significant impact on the overall product, the high-resolution mobile AMOLED like the present invention If an accurate mask frame element such as the prior art is used, it is difficult to meet high-quality output.

However, like the present invention, the position regulator 121 driven by the servo motor 122 and the contact portion 123 is used to adjust the air-floated frame, so that accurate mask frame elements can be manufactured, and therefore, the movement of the mask frame elements can be used. Use AMOLED panels to produce high-quality panels while also increasing mass production output.

The servo motor 122 accurately rotates the servo motor shaft while horizontally moving the contact portion 123 in contact with the outside of the frame forward and backward in a μm unit. Therefore, the frame does not move excessively due to the contact portion. If excessive force is generated, it is not forced to clamp, but the air-floating frame moves excessively. It is difficult to position, but the present invention uses a servo motor and the short position adjusters on both sides facing each other accurately advance and retreat, and therefore can be accurately centered and aligned.

When centering and aligning the frame, each position adjuster 121 arranged face to face with the short side or the long side of the frame, when the contact portion 123 on one side is in contact with the frame, the side moves forward to adjust the frame position, and then At this position adjustment level, the corresponding position adjuster on the other side contacts the frame to correct the position, and then adjust the centering to perform the alignment.

In another method, the position adjusters 121 facing each other are in contact with the frame at the same time. If one side moves forward, the position adjuster on the opposite side is controlled to move backward while adjusting the position of the frame to perform the alignment according to centering.

Similarly, when aligning the short-side frame, the position adjuster 121 on the long-side can adjust the centering by the above two methods, or adjust the short-side frame after the alignment of the short-side position is completed.

In the above, the alignment of the position adjuster in contact with the short side is aligned with the long side frame of the frame, and the alignment criterion of the position adjuster in contact with the long side is aligned with the short side direction of the frame.

In addition, in the present invention, when aligning the positions of the short side or the long side of the frame, the order in which direction should be aligned first is not specified. According to needs, the first alignment in a certain direction or simultaneous alignment is selectively performed. In addition, the position adjuster 121 contacting each short side or the long side first aligns one side or simultaneously contacts to perform alignment is also optional adjustment, and the order is not specified.

The frame lifting part 130 welds the divided mask to the frame after placing the conveyed frame on the upper part of the frame position alignment part 1, and then the frame lifting part 130 plays a role of lifting.

The frame lifter 130 is composed of four corner lifters 131 and four frame long-side lifters 132 according to the structure of the air hood 112 divided into four parts. The long-side lifter and one corner lifter are located on one long side. They are connected by connecting rods 133 to form a pair, and move up and down at the same time. The driving source for vertical lifting of the corner lifter and the long-side lifter is hydraulic or pneumatic or servo motor lifting.

In addition, the corner lifter and the long-side lifter form a spring 134 in a vertical direction to provide cushioning force.

In addition, according to the structural characteristics of the hood 112 divided into four parts, the position of the contact support part 135 between the long side lifter and the upper part of the corner lifter (the contact at the upper corner of the corner lifter located at the corner) The position of the support portion 135) is arranged at a higher level than the frame located at the upper part The position further inward in the diagonal direction is similarly located at the position of the contact support portion 136 on the upper part of the long side lifter on the long side, which is also provided at a position further inward than the upper frame.

Different from the prior art, the above structure supports the corners and long sides from the inside, and then raises or lowers the lower part of the frame in a state where the weight is stable.

FIG. 9 is a manufacturing flow chart of an AMOLED movable mask frame element using a single tension welding device according to an embodiment of the present invention.

The manufacturing method of the mask frame element according to the single tension welding device of the present invention having the structure disclosed in FIGS. 1 to 7 has the following manufacturing process.

In step S100, the frame lifting part 130 is raised to load the conveyed frame and then descends, and then the frame is placed on the gas cover 112 of the frame position alignment part 1.

Then, in step S200, the gas hood portion 112 divided into four parts uniformly sprays the gas supplied from the air floatation portion 110 to stably float the frame.

Then, in step S300, the frame contacted by the frame position adjusting part 120 of the frame position alignment part 1 is moved forward and backward to align the frame in the air-floating state according to the reference.

Then, in step S400, if the centering of the frame is finished, the clamping portion clamps the split mask and moves to the welding position on the frame, and then locates the position of the split mask while applying tension.

Then, in step S500, the three-head welding and detection unit 2 moves to check whether the transported split mask is aligned with the welding position of the frame before welding. Among them, the three-head welding and detection unit 2 consists of two The welder parts 210 and 220 and the welding quality detector 234 are constituted.

Then, in step S600, after the welding is finished, the welding quality detector 234 detects the welding quality while adjusting the weight balance.

In step S700, the step of inspecting the welding quality after transporting and welding the divided mask is repeated. If the manufacturing of the mask frame element is completed, the frame lifting part 130 raises the mask frame element.

It also has the following step: when the frame to be transported is lowered or the mask frame element whose welding has been completed is raised, the frame lifting portion 130 descends or rises while supporting the lower corners and long sides of the frame at the same time.

Specifically, according to the structure of the hood 112 divided by four parts, the frame lifting part 130 is composed of four corner lifters 131 and four long side lifters 132 of the four frames. The long-side lifter and a corner lifter are connected by a connecting rod 133 to form a pair, and then the long-side lifter is linked with a corner lifter for lifting at the same time.

The drive source for vertical lifting of the corner lifter and the long-side lifter can be carried out by hydraulic or pneumatic means or by means of a servo motor.

In addition, the corner lifter and the long-side lift block form a spring 134 in a vertical direction, thereby providing a cushioning force.

In addition, according to the structural characteristics of the hood 112 divided into four parts, the position of the long side lifter and the upper contact support part 135 of the corner lifter (at the corner contact support part at the upper corner of the corner lifter 135) is set at a position further inward in the diagonal direction than the upper frame. Similarly, the position of the contact support portion 136 on the upper part of the long side lifter on the long side is also set at the position compared to the upper part. The frame is positioned further to the inside.

Different from the prior art, the above structure supports the corners and long sides from the inside, and then raises or lowers the lower part of the frame in a state where the weight is stable.

It also has the following steps: the frame position adjusting portion 120 is provided with a position adjuster 121 driven by a servo motor 122 and a contact portion 123 corresponding to the short side and the long side, respectively, and operates the servo when the contact portion 123 is in contact with the frame The motor 122 finely adjusts forward and backward.

According to an embodiment, it is preferable to form two and three position adjusters 121 on each short side and each long side. With this configuration, the position adjusters located on the short and short sides facing each other and the long and long sides facing each other accurately advance and retreat to adjust so that the contact portions 123 contact each of the air-floating frame. Position the centering position in the side state. Such a position adjuster is aligned with the centering position of the frame within 5 μm based on the centering position reference.

The method includes the following steps. When adjusting the position of the frame, the position adjusters that contact the frame on the long side and the short side move simultaneously to perform alignment operations or move individually for alignment.

When centering and aligning the frame, each position adjuster 121 arranged face to face with the short side or the long side of the frame, when the contact portion 123 on one side is in contact with the frame, the side moves forward to adjust the frame position, and then At this position adjustment degree, the corresponding position adjuster on the other side contacts the frame to correct the position, and then adjust the centering to perform the alignment.

In another method, the position adjusters 121 facing each other are in contact with the frame at the same time, and if one of the sides advances, the position adjuster on the opposite side is controlled to move backward while adjusting the position of the frame, and the alignment is performed according to the centering.

Similarly, when aligning the short-side frame, the position adjuster 121 on the long-side can adjust the centering by the above two methods, or adjust the short-side frame after the alignment of the short-side position is completed.

In the above, the alignment of the position adjuster in contact with the short side is aligned with the long side frame of the frame, and the alignment criterion of the position adjuster in contact with the long side is aligned with the short side direction of the frame.

In addition, in the present invention, when aligning the position of the short side or the long side of the frame, the order in which direction should be aligned first is not specified. According to needs, the first alignment in a certain direction or simultaneous alignment is selectively performed.

In addition, the position adjuster 121 contacting each short side or the long side first aligns one side or simultaneously contacts to perform alignment is also optional adjustment, and the order is not specified.

The step S500 includes the following steps: the welding position detectors 215, 225 constituting the respective welder parts 210, 220 check whether the welding position of the loaded segmentation mask and the frame are aligned; then, when the welding position is aligned, The welders 214, 224 constituting the respective welder parts 210, 220 perform precise welding while moving along the welding rails 216, 226 when the platform is stagnant. The welding rails 216, 226 are aligned with the moving direction of the platform. The same axial direction configuration.

In this way, when the weight balance of the gantry is adjusted in a balanced manner by the two welder parts 210 and 220, only the welding detector part 230 moves horizontally on the gantry to detect the welding quality of the divided masks welded to the frame. There will be weight changes caused by movement, so the state of suppressing vibration is good to achieve accurate detection of welding quality.

The welding quality tester 234 measures the welding quality with the weight balance adjusted as follows: the two welder parts 210 and 220 suspended on the platform are located at both ends and are in a stagnant state without moving to make them stand up. The welding quality tester 234 in the state of the weight balance function confirms the welding quality of the left and right divided masks.

Therefore, accurate welding can be performed without vibration occurring when the gantry moves along the welding part.
