Double tension type welding device for manufacturing AMOLED mobile mask frame element and method of manufacturing AMOLED mobile mask frame element using the device

The present invention relates to a dual-tension type welding device for manufacturing AMOLED mobile mask frame elements and a method for manufacturing an AMOLED mobile mask frame element using the device, and more specifically, to a frame mounted for manufacturing mask frame elements Perform air flotation to accurately center and align, and use the double clamping part to simultaneously clamp the two split masks and place them symmetrically on the frame before welding to prevent the occurrence of asymmetric welding in sequence The frame is deformed, thereby improving the quality of the mask frame element while shortening the manufacturing time, and a method of manufacturing the mask frame element using the device.

Recently, OLED (Organic Light Emitting Diode) has attracted much attention as a display element for various uses, its reaction speed is much faster than that of a thin film transistor liquid crystal display (TFT LCD), and it can be used without a separate backlight It is self-luminous and has a simple structure and fewer components compared to LCD, which can greatly reduce the thickness and weight of LCD compared with LCD. It has a wide viewing angle and low power consumption structure, so it is the next generation display device.

The OLED is divided into an active mode (AM) and a manual mode (PM). In particular, each pixel of AMOLED has TFTs and capacitors, and is excellent in power consumption, life, and resolution. Therefore, to overcome the shortcomings of TFT manufacturing with high manufacturing costs, it is trying to actively develop and Mass production.

In particular, AMOLED has recently been used as a display element in various fields, and the most representative fields among them are large display devices such as TVs and small display devices such as smartphones. In particular, the field of smart phones is an area where new products are launched every year and the replacement needs of users are also very active, so its business prospects are very bright.

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

The manufacturing process of a conventional mask frame element manufacturing method using a split mask is outlined as follows: a loading frame such as a transport device and a lifting table is placed at a reference point centering position, and then the split mask captured by the gripper is transported to Align and clamp the working position, and then shoot the split mask image based on the mother glass located under the split mask to detect PPA (Pixel Position Accuracy, pixel position accuracy). If the detected split mask shape information is within the tolerance of the PPA Within the range, the split mask is welded and fixed to the frame, and then the detection, correction and welding steps are repeated for the new split mask in the same method to manufacture the mask frame element.

However, in the existing mask frame component manufacturing process as described above, the process of loading the frame and aligning the reference centering is the most important process to determine the output of the mask frame component, and the existing frame process has some Exact structural problems.

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

That is, when the long side or short side of the frame is moved by the cylinder, it is difficult to control the position with a precise value by using the hydraulic or pneumatic cylinder operation method, even if it is accurately aligned with the centering position of the frame during measurement, if it is contacted and supported When the ball float on the lower part of the frame is lowered and impact is applied, a slight change is required. However, in the case of a slight position change, there is a problem that an accurate mask frame element that requires an error in micrometers cannot maintain high quality. problem.

In addition, the existing manufacturing method of the mask frame element is that when the frame is welded to the divided mask, a clamping portion is used to alternately transport a divided mask to the left and right based on the centering position of the frame, and then hang on a table at that position The welding machine of the frame confirms the welding position and performs welding; however, this manufacturing method has the following problems: in the order of welding in accordance with the welding order of the divided mask welded to the frame Since the number of divided masks changes at any time, it is difficult to obtain high-quality mask frame elements by repeating the deformation of the frame shape by the asymmetric reaction force on the frame.

In addition, the prior art also has the following problems: after centering the frame, the grabber is used to load the split mask, and then the position is aligned, and then the welding is performed to detect the welding position and confirm the welding state after welding. In order to ensure the welding position and welding quality, it is difficult to guarantee high-quality mask frame components in order to achieve accurate measurement at this time. This is because the double-head detection and welding device used in the prior art to detect the welding quality between the frame and the split mask is generally constituted by two welding devices suspended on a transfer stand, and the two welding One welding device in the device is also provided with a welding quality detection device. The dual-head welding and inspection device of 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 divided mask, and the welding device moves slightly on the stage. The change of the center of gravity of the weight also generates vibration, so the accuracy can be reduced during the inspection.

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

In the following, the structure and function of the embodiment of the present invention will be described in detail with reference to the drawings. In the description of the present invention, if it is determined that the detailed description of the related well-known functions or configurations unnecessarily makes the gist of the present invention unclear, the detailed description will be omitted.

1 is a perspective view showing the overall structure of a double tension welding device according to an embodiment of the present invention; FIG. 2 is an example view showing a double clamping portion according to an embodiment of the present invention; FIG. 3 is a frame according to an embodiment of the present invention. Contrast welding of two split masks symmetrically and symmetrically at the same time and sequential welding by the existing method results in an asymmetric stress comparison chart.

As shown in the figure, the double-tension welding device for manufacturing a mask frame element of the present invention includes: a frame position alignment portion 1 to install the loaded frame 5 in a state of being air-floated using the air-floating portion 110, and then utilize the frame position The adjustment part 120 is aligned with the reference centering position to provide resistance (apply tension); the double-head or three-head welding and detection part 2 is hung on each of the gantry 20a, 20b constituting the dual gantry part 20 to move, and at the same time For one or two split masks located on the upper part of the frame, the welding position is aligned and then welded, and then the welding quality is detected; the double clamping part 3 simultaneously clamps the two split masks 6 loaded on the mask frame 4 to be transported to Accurately align the upper part of the frame, and then apply the opposing force.

The double tension welding device having the frame position alignment portion 1 is used to accurately adjust the position of each frame position adjusting portion 120 in the state of air-floating the frame 5 when manufacturing the AMOLED mobile mask frame element. The position adjustment part 120 is provided to face each other with the short side and the long side of the frame, and then the air floating state is released by the air floating part 110, and then the frame is accurately adjusted within the range of 5 μm based on the centering position. At this time, the frame position alignment part has an alignment function that integrates the frame and the camera axis after centering the frame, and at the same time, it also takes into account the confrontation for compensating for the deformation of the frame when welding is performed after providing tension to the mask after alignment Force acting device.

In addition, the air float 110 is constituted by the air float 110 that separately divides the area corresponding to the short side and the long side of the frame when the frame 5 is air floated. Therefore, uniform and independently injected air is stably supplied to the short side of the lower part of the frame and The lower surface of the long side can eliminate the air float stably. If the air float is eliminated, the frame accurately aligned in the air-floated state is placed on the platform without impact to achieve accurate centering alignment.

In addition, the double-tension welding device having the welding and detection section 2 uses two pairs of grippers 3a, 3b constituting the double-holding section 3 to hold the two divided masks mounted on the mask frame section 4 at a time in a double-tension manner The cover 6 is then symmetrically loaded on both sides with the centering position of the center of the frame 5 as a reference to align the welding position, and then the frame and the two are welded simultaneously using the two welder parts 210, 220 suspended on the respective stands 20a, 20b After dividing the masks, the welding quality is detected by the central welding detector 230.

When the welding and detecting section 2 is configured by a double-headed method, the welding detector section 230 is located together with the welding unit sections 210 and 220 suspended on one side of each of the stands 20a and 20b to detect the welding position and then performs welding. Detect the welding quality of the split mask frame welded to the frame.

In addition, in the case of a three-head method instead of a two-head method, the two welder parts 210 and 220 suspended on each of the stands 20a and 20b function as a weight balance, and then the weight of the stand is adjusted in a balanced manner. In this state, only the central welding detector unit 230 moves on each of the gantry 20a, 20b to perform detection, and a sudden weight change does not occur, thereby realizing accurate detection while suppressing the occurrence of vibration.

In addition, the double-tension welding device having the welding and detection unit 2 configured by the three-head method, when manufacturing the AMOLED moving mask frame element, the two welding parts 210 composed of the three-head method at each stage 20a, 20b, 220 not only plays a role in balancing the weight, but also makes the welding machine move independently and accurately in the welding track composed of the same axis direction as the movement direction of each stand 20a, 20b when the stand 20a, 20b is stopped during welding. The accurate detection and welding of the welding position can be achieved without vibration occurring when the gantry moves.

The double clamping part 3 is a device that moves along two conveyer rails formed in the double tension welding device, respectively, compared with a general clamping part that clamps both ends of the divided mask and then transports It consists of a pair of holders. The present invention constitutes two pairs of holders holding at most two divided masks at a time for transportation.

The reason for constructing the above structure is to solve the following problem: in the prior art, a pair of clamping parts transports a split mask at both ends and then applies an opposing force. In this state, the upper part of the frame In the process of welding with the frame after the quasi-position, until the next split mask is delivered to apply the opposing force to complete the welding, the number of split masks welded to the frame is not symmetrical in both directions, maintaining an asymmetrical resistive force Therefore, until the final mask frame element is completed, the asymmetric deformation and symmetrical state continue to appear repeatedly on the frame, so it is difficult to produce a high-quality mask frame element. That is, in order to solve this problem in the present invention, at first, only one split mask is positioned at the center of the frame for welding at a time, and then the two gripping parts formed by the two pairs are used to simultaneously grip the two split masks In the state of the cover, with the center of the frame as a reference, it is symmetrically arranged on both sides and welded at the same time, so that the opposing force of the split mask acting on the frame is always applied symmetrically. Therefore, if the process of the present invention is carried out, frame deformation will not occur until the final mask frame element is completed, so that a high-quality mask frame element can be stably manufactured.

In addition, there is a hydraulic or pneumatic application tool and a servo motor, the hydraulic or pneumatic application tool is located on both sides of the split mask constituting the double clamping portion to provide clamping force to clamp the split mask respectively, the servo The motor advances and retracts the gripper to apply precise tension. Since this structure is a well-known structure in this field, its detailed description is omitted.

The mask frame part 4 is a tool for loading divided masks arranged in a plurality, and can further shorten the process time required for manufacturing the mask frame element. The upper and lower multi-layer structure constitutes that each layer is loaded with a plurality of divided masks Cover the carrier and supply the carrier in turn. At this time, when the double clamping part of the present invention transports the mask for clamping the two divided masks, only one mask frame part is provided, and the pair of clamping parts are sequentially held, and after confirming the two clampings It can also be moved at the same time, but depending on the situation, it is also equipped with two mask frame parts that are simultaneously clamped and transported.

In addition, the position of the mask frame part is only provided on one side end in the drawing of an embodiment of the present invention, but two mask frame parts may be formed on one side end as needed, or on both side ends. Set one.

The structure of the mask frame portion is not the core structure of the present invention, but a structure including a known general mask frame portion, and therefore detailed description thereof is omitted.

Hereinafter, the frame alignment unit and the welding and detection unit configured by a two-head and three-head system according to the present invention will be described in detail.

FIG. 4 is an example diagram showing a frame position alignment portion having air holes with divided regions according to an embodiment of the present invention; FIG. 5 is a diagram showing individual air hoods placed on the frame position alignment portion of an embodiment of the present invention. Perspective view; FIG. 6 is a diagram showing the individual Rear view of the hood; FIG. 7 is an example diagram showing a frame position alignment portion where a separate air hood portion is placed according to an embodiment of the invention; FIG. 8 is a frame position alignment portion loading showing an embodiment of the invention An example of a state where the frame is aligned with the frame.

The frame position alignment portion 1 of the present invention generally includes: an air float portion 110 that raises the loaded frame to a predetermined height and descends; a frame position adjustment portion 120 that accurately adjusts the position of the air float frame according to a reference center; The frame lifting part 130 is placed on the upper part of the frame position alignment part 1, and the frame lifting part 130 is lifted after the frame is welded and divided into masks.

First, the air floating portion 110 is composed of a plurality of air hole portions 111 and a plurality of air cover portions 112 provided above the air hole portions. When the frame elevating portion 130 is lowered after loading the frame, the air float 110 sprays air to keep the frame floating in a balanced manner. In such a floating state, if the frame position adjustment part 120 is accurately aligned with the centering position, the air supply to the air-floating frame is gradually released, and the aligned state is maintained to be placed on the upper surface of the air hood part 112 .

The air hole portion 111 receives compressed air through an air compression line connected to an unillustrated air compressor, and then ejects the compressed air. In particular, the air hole portion 111 is composed of a protruding support frame 111a and a plurality of protruding support frames. The air hole 111b is configured such that the air chamber 112a formed at the lower portion of the air cover portion 112 placed above the air hole portion 111 is inserted into the protruding support frame 111a and supported, and air is supplied to the interior space of the air chamber through the air hole .

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

As described above, the reason for providing a plurality of air hole portions with the air injection area being independently divided is as follows: If a single air hole portion is constituted by a structure divided into four pieces, compressed air cannot be uniformly supplied to the lower part of the frame, When compressed air is supplied from the side, a stable and uniform air float cannot be achieved, and it is difficult to provide accurate centering alignment when the frame is tilted to one side.

The upper portion of the air cover portion 112 is processed into a flat shape, and an air chamber 112a is formed in the inner surface direction of the lower surface. 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 portion of the air chamber 112a. In addition, the gas mask portion 112 is provided with two on the long side, respectively The air holes 111b of the stay 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 reasons for forming the plurality of air cover portions 112 having the air chamber 112a in the lower portion and the two air chambers below the long-side side air cover portion are as follows: the received air is uniformly filled in the air chamber interior After that, it is supplied to the lower part of the frame through the air holes with a uniform pressure, and then floats the frame with a uniform height to achieve accurate centering.

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

The frame position adjusting section 120 constitutes a position adjuster 121 on the short side and the long side. The position adjuster 121 is composed of a servo motor 122 and a contact section 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 on the short side and the short side and the long side and the long side facing each other face to face with each other accurately advance and retreat to adjust to adjust each contact of the air-floating frame by the contact portion 123 Position the centering position on the side. Such a position adjuster aligns the centering position of the frame within 5 μm on the basis of the centering position reference.

In the prior art, a cylinder is used to center the frame, but the cylinder cannot advance and retreat to a precise position, and it is difficult to accurately adjust the position of the frame, and thus the mask cannot be accurately positioned on the frame in the unit level of μm. Since soldering cannot be performed, 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 conventional mask frame element is a low-resolution screen. Although the slight difference does not greatly affect the overall product, it is as high-resolution mobile AMOLED as the present invention. If an accurate mask frame element such as the prior art is used, it is difficult to satisfy high-quality production.

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

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

When aligning the frame with the center, each position adjuster 121 provided face-to-face with the short or long side of the frame, with one side of the contact portion 123 in contact with the frame, advance the side to adjust the position of the frame. At this degree of position adjustment, the corresponding position adjuster on the other side contacts the frame to correct the position, and then adjusts 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 retreat while adjusting the position of the frame, and the alignment is performed according to centering.

Similarly, when aligning the short-side frame, the position adjuster 121 located on the long side can adjust the centering by the above two methods, or can adjust the short-side frame after the short-side position alignment 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, it is not specified which direction should be aligned first. According to the need, the first alignment or the simultaneous alignment is selectively performed. In addition, the position adjuster 121 contacting each short side or long side is firstly aligned to one side or simultaneously touched to perform alignment is also selective adjustment, and the order is not specified.

The frame elevating portion 130 places the transported frame on the upper portion of the frame position alignment portion 1 and welds the divided mask to the frame. After that, the frame elevating portion 130 functions to lift up and down.

The frame lifting section 130 is composed of four corner lifters 131 and four frame long-side lifters 132 according to the structure of the air hood section 112 divided into four parts. The long-side lifter and the corner lifter located on one side of the long side They are connected in pairs by connecting rods 133 and move up and down while interlocking. The driving source for lifting the corner lifter and the long-side lifter in the vertical direction is to use a hydraulic or pneumatic method or a servo motor for lifting.

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

In addition, according to the structural characteristics of the air cover portion 112 divided into four parts, the installation position of the contact support portion 135 of the long-side lifter and the upper portion of the corner lifter (the contact support portion at the corner of the upper portion of the corner lifter located at the corner portion) 135 position) is set diagonally compared to the upper frame The position further inward in the line direction is also provided at a position further inward than the frame located at the upper part of the contact support portion 136 at the upper part of the long-side lifter on the long side.

Unlike the prior art, with the above structure, the corner and the long side are supported from the inside, and then the lower part of the frame is raised or lowered with the center of gravity stable.
