Description

Technical Field

[0001] The present invention relates to the technical field of panel bonding, and particularly relates to a panel vacuum bonding device and its application. Background Art

[0002] Currently, when manufacturing a display screen, there is a situation where a large panel and multiple small panels are bonded together for use. However, when operating manually, multiple small panels cannot be bonded simultaneously. Bubbles usually occur when the small panels are bonded sequentially. Bubbles will also be generated due to out-of-sync operation if two people operate separately, which affects the quality of the display screen. Moreover, manual bonding is also time-consuming and laborious, and the bonding efficiency is not high. Summary of the Invention

[0003] Based on this, it is necessary for the present invention to provide a panel vacuum bonding device that can automatically and synchronously bond multiple small panels, reduce bubbles, and improve the bonding efficiency.

[0004] The present invention also provides the application of the above panel vacuum bonding device.

[0005] In order to achieve the object of the present invention, the present invention adopts the following technical solutions:

[0006] A panel vacuum bonding device, comprising:

[0007] A lower platform, a lower cavity is provided in the middle of the lower platform. The lower platform includes a panel installation position and a platform installation position. The panel installation position is closer to the lower cavity than the platform installation position. A positioning elastic member is installed on the top of the platform installation position and a positioning sliding member is placed; and

[0008] An upper platform, an upper cavity is provided in the middle of the upper platform. The upper platform is located above the lower platform and corresponds to the platform installation position. The bottom of the upper platform is connected to the positioning elastic member and abuts against the positioning sliding member; when the upper platform moves towards the lower platform, the positioning sliding member slides out between the edges of the lower platform and the upper platform, and the upper platform finally moves to the platform installation position; compared with manual bonding, the bonding efficiency is also greatly improved.

[0009] In the above panel vacuum bonding device, the lower panel is placed on the lower platform, and the upper panel is placed on the upper platform. In a vacuum environment, due to negative pressure, the upper platform will drive the upper panel to move towards the lower platform. The positioning sliding member slides out, and the positioning elastic member is compressed. Thus, the upper platform and the lower platform abut against each other, and the upper panel and the lower panel are sucked together, thereby completing the simultaneous bonding of multiple panels to one panel, reducing bubbles caused by out-of-sync, and improving the quality of the display screen.

[0010] In some of these embodiments, the position of the panel mounting position is higher than the position of the platform mounting position, and the position of the panel mounting position does not exceed the position of the top surface of the upper platform when the upper platform fits the lower platform, and the shape of the platform mounting position matches the shape of the upper platform so that the upper platform can be completely positioned on the platform mounting position.

[0011] In some of these embodiments, a mounting groove is formed on the top surface of the lower platform, one end of the positioning elastic member is mounted in the mounting groove, and the other end extends upward to connect the upper platform.

[0012] In some of these embodiments, mounting posts are provided in the mounting groove, there is a mounting gap between the mounting posts and the inner wall of the mounting groove, and the top surface of the mounting posts does not protrude from the opening surface of the mounting groove. One end of the positioning elastic member is mounted in the mounting gap, and the other end extends upward to connect the upper platform.

[0013] In some of these embodiments, a positioning post extending toward the upper platform is mounted on the top surface of the lower platform, and a positioning hole is formed in the upper platform corresponding to the position of the positioning post, and the positioning post extends into the positioning hole.

[0014] In some of these embodiments, an exhaust groove is formed on the top surface of the upper platform, and the exhaust groove extends from the inner edge of the upper platform to the outer edge of the upper platform to communicate the upper cavity with the external environment.

[0015] In some of these embodiments, the number of the exhaust grooves is multiple, and they are spaced apart and formed on the upper platform.

[0016] In some of these embodiments, the positioning sliding member is a positioning wheel, and the opposite two planes of the positioning wheel respectively abut against the lower platform and the upper platform.

[0017] In some of these embodiments, the panel mounting position and the platform mounting position are arranged adjacent to each other.

[0018] The present invention also provides an application of the panel vacuum laminating device as described above in laminating between a large panel and a small panel. Description of the Drawings

[0024] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] Embodiment

[0027] Please refer to Figure 1 , the present invention provides a panel vacuum bonding device 100 for bonding a panel and a panel, or for simultaneously bonding multiple small panels and a large panel. The panel vacuum bonding device 100 includes a lower platform 10 and an upper platform 20. A lower cavity 11 is formed in the middle of the lower platform 10 to form a frame-shaped lower platform. The lower platform 10 includes a panel mounting position 12 and a platform mounting position 13. The panel mounting position 12 is closer to the lower cavity 11 than the platform mounting position 13. A positioning elastic member 30 is mounted on the top of the platform mounting position 13 and a positioning sliding member 40 is placed thereon; an upper cavity 21 is formed in the middle of the upper platform 20 to form a frame-shaped upper platform. The upper platform 20 is located above the lower platform 10 and corresponds to the platform mounting position 13. The bottom of the upper platform 20 is connected to the positioning elastic member 30 and abuts against the positioning sliding member 40; when the upper platform 20 moves towards the lower platform 10, the positioning sliding member 40 moves out along the edge between the lower platform 10 and the upper platform 20, and the upper platform 20 finally moves to the platform mounting position 13.

[0028] In use, the lower panel is placed in the middle of the lower platform 10, and the edge of the lower panel corresponds to the panel mounting position 12. The upper panel is placed on the upper platform 20. At this time, due to the interval of the positioning sliding member 40, there is a gap between the upper platform 20 and the lower platform 10. When the device is placed under vacuum conditions, the upper panel moves towards the lower panel under negative pressure. At the same time, the upper platform 20 moves to the platform mounting position 13 of the lower platform 10, and the positioning sliding member 40 slides out between the upper platform 20 and the lower platform 10, and the positioning elastic member 30 is compressed until the upper panel and the lower panel are completely attached. The above device can complete the simultaneous attachment of multiple panels to one panel, reduce the bubbles caused by non-synchronization, and improve the quality of the display screen.

[0029] In one embodiment, the outer edge of the lower platform 10 protrudes from the outer edge of the upper platform 20, so that the upper platform 20 can be more conveniently positioned on the lower platform 10, and it is also convenient to move the entire device. That is, the lower platform 10 further includes a protruding portion 17 that protrudes from the upper platform 20.

[0030] In one embodiment, the position of the panel mounting position 12 is higher than the position of the platform mounting position 13, but the position of the panel mounting position 12 cannot exceed the top surface position of the upper platform 20 when the upper platform 20 is attached to the lower platform 10. The shape of the platform mounting position 13 matches the shape of the upper platform 20, so that the upper platform 20 can be completely positioned on the platform mounting position 13. In this way, when the upper platform 20 moves down to the lower platform 10 and the negative pressure reaches a certain vacuum degree, the upper panel can cover the lower panel, and the amount of negative pressure applied can be reduced.

[0031] In one embodiment, the platform mounting position 13 is adjacent to the panel mounting position 12. That is, the platform mounting position 13 is arranged close to the panel mounting position 12, so that the upper panel and the lower panel can be as flush as possible, reducing subsequent shearing work.

[0032] Please refer to Figure 2 , in one embodiment, an installation groove 15 is formed on the top surface of the lower platform 10, and one end of the positioning elastic member 30 is installed in the installation groove 15, and the other end extends upward to connect the upper platform 20. This can make the positioning elastic member 30 more stable and reduce the deviation of the upper platform 20 caused by the positioning elastic member 30.

[0033] In one embodiment, an installation post 16 is provided in the installation groove 15. There is an installation gap between the installation post 16 and the inner wall of the installation groove 15, and the top surface of the installation post 16 does not protrude from the opening surface of the installation groove 15. One end of the positioning elastic member 30 is installed in the installation gap, and the other end extends upward to connect the upper platform 20. This makes the end installation of the positioning elastic member 30 more stable and reduces the deviation of the upper platform 20 caused by the positioning elastic member 30.

[0034] The above-mentioned positioning elastic member 30 can be a component with elastic contraction ability such as a spring or a spring piece, etc., and all can be installed here to realize its corresponding function.

[0035] In one embodiment, the number of the positioning elastic members 30 is multiple, and they are installed on the platform installation position 13 at intervals. Using multiple positioning elastic members 30 to position the upper platform 20 makes the panel positioning more stable and accurate when fitting.

[0036] Please refer to Figure 1 and Figure 3 , in one embodiment, the positioning sliding member 40 is a positioning wheel, and the opposite two planes of the positioning wheel respectively abut against the lower platform 10 and the upper platform 20. In this way, when the upper platform 20 and the lower platform 10 approach each other, due to the extrusion force, the positioning wheel can be extruded between the upper platform 20 and the lower platform 10, thereby completing the alignment of the upper platform 20 and the lower platform 10. Of course, the above-mentioned positioning sliding member 40 can also be other positioning components, as long as it is easy to slide relative to the upper platform 20 and the lower platform 10 under the extrusion force. For example, the positioning sliding member 40 can also be a slider, a sliding bar, etc.

[0037] Please refer to Figure 1 and Figure 4 , in one embodiment, a positioning post 50 extending towards the upper platform 20 is installed on the top surface of the lower platform 10, and a positioning hole 22 is opened at the position of the upper platform 20 corresponding to the positioning post 50, and the positioning post 50 extends into the positioning hole 22. When positioning by the positioning elastic member 30, since the positioning elastic member 30 is relatively soft, the upper platform 20 may shift in position. At the same time, the positioning post 50 positions the upper platform 20, which can ensure that the position of the upper platform 20 does not shift.

[0038] Please refer to Figure 1 and Figure 5 , in one embodiment, an exhaust groove 23 is opened on the top surface of the upper platform 20, and the exhaust groove 23 extends from the inner edge of the upper platform 20 to the outer edge of the upper platform 20, so that the exhaust groove 23 communicates the upper cavity 21 with the external environment. In this way, when the upper panel and the lower panel are fitted together, as the edges of the upper panel and the lower panel are fitted together, the bubbles between them can be discharged to the outside through the exhaust groove 23, thereby reducing the bubbles formed on the product, and further improving the quality of the product.

[0039] In one embodiment, the number of the exhaust grooves 23 is multiple, and they are opened on the upper platform 20 at intervals, thereby exhausting air at multiple positions between the edges of the upper panel and the lower panel.

[0040] The present invention also provides an application of the above-mentioned panel vacuum fitting device 100 in fitting between a large panel and a small panel.

[0041] For example, when using the above-mentioned panel vacuum bonding device 100 to bond a large panel with two small panels, first place the large panel in the middle of the lower platform 10, with the edges of the large panel corresponding to the panel mounting positions 12. Place the small panels on the upper platform 20 one by one and align them, thus forming a large panel. At this time, due to the spacing of the positioning sliding members 40, there is a gap between the upper platform 20 and the lower platform 10. When the device is placed under vacuum conditions, the upper panel moves towards the lower panel under negative pressure. At the same time, the upper platform 20 moves to the platform mounting position 13 of the lower platform 10, and the positioning sliding members 40 slide out between the upper platform 20 and the lower platform 10, compressing the positioning elastic members 30 until the upper panel and the lower panel are bonded together. Continue to apply negative pressure, and the bubbles at the edges of the upper panel and the lower panel are discharged through the exhaust grooves 23, thus automatically completing the bonding of a large panel with several small panels.

[0042] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
