[0057] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. The technical features designed in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0058] In the description of the present invention, it should be noted that all terms used in the present invention (including technical terms and scientific terms) have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs, and should not be construed as a limitation of the present invention. It should be further understood that the terms used in the present invention should be understood as having a meaning consistent with their meaning in the context of this specification and the relevant art, and should not be understood in an idealized or overly formal sense, unless clearly defined as such in the present invention.

[0059] The present invention provides a two-in-one screen assembly machine as shown in Figures 1-18 the embodiment, which includes an assembly mechanism 400, which includes at least one multi-angle transfer arm 410, a bracket 420, and a backlight panel loading component 430 for transporting the backlight panel to the lower part of the bracket 420; the multi-angle transfer arm 410 includes a jig 411 for adsorbing the panel at its bottom and a multi-angle movement mechanism 412;

[0060] The multi-angle movement mechanism 412 includes:

[0061] A first rotation component 4121, which is connected to the top of the jig 411 to drive the jig 411 to rotate longitudinally;

[0062] A second rotation component 4122, which is connected to the first rotation component 4121 to drive the jig 411 to rotate vertically;

[0063] A first Z-axis movement component 4123, which is connected to the second rotation component 4122 to drive the jig 411 to move vertically; and it is slidably connected to the bracket 420, so that the multi-angle transfer arm 410 alternately moves through the bracket 420 above the panel loading station and the backlight panel loading component 430.

[0064] Specifically, during the assembly process, the workflow is as follows: The backlight panel loading component 430 transports the backlight panel to below the bracket 420. The multi-angle transfer arm 410 grabs the panel from the panel loading station, moves horizontally along the bracket 420 to above the backlight panel loading component 430, and places and presses the panel onto the backlight panel to assemble the two.

[0065] Among them, the fixture 411 carries the panel on its bottom surface. In the assembly and attachment process (the process of attaching the backlight panel to the surface of the panel), due to the special structural characteristics of the curved screen, it is not feasible to directly place the panel horizontally for attachment as in the flat screen assembly and attachment process, and the attachment effect of the product is not good. The multi-angle transfer arm 410 is provided with a first rotation component 4121 connected to the top of the fixture 411. The first rotation component 4121 is used to drive the fixture 411 to rotate longitudinally (i.e., rotate around the Y axis). The rotation state of the multi-angle transfer arm 410 in the attachment process is as Figure 9 shown. Performing the attachment process on one side of the panel in this rotation state can make the two attach tightly, and the attachment effect is significantly improved. Similarly, the longitudinal rotation angle can be adaptively adjusted to complete the attachment work of other parts of the panel.

[0066] In addition, during the production process, when transferring the panel from one station to the next station, it is often necessary to change its orientation. By setting a second rotation component 4122 connected to the first rotation component 4121, the second rotation component 4122 is used to drive the first rotation component 4121 to rotate vertically (i.e., rotate around the Z axis), thereby driving the fixture 411 to rotate vertically and changing the position of the panel, which is convenient and practical.

[0067] The specific use of the multi-angle transfer arm 410 is as follows: The multi-angle transfer arm 410 grabs the panel from the panel loading station, moves horizontally along the bracket 420 to above the backlight panel loading component 430. The multi-angle transfer arm 410 moves horizontally along the bracket 420 to above the backlight panel loading component 430. The first rotation component 4121 drives the fixture 411 to rotate longitudinally to adjust to an appropriate angle, and then the first Z-axis moving component 4123 drives the panel on the fixture 411 to move downwards, presses the panel on the backlight panel, and the two complete the assembly.

[0068] In summary, in the two-in-one screen assembly machine provided by the present invention, the multi-angle transfer arm 410 can drive the panel to adjust its position in multiple directions, accurately position it at the working station, and achieve the effect of precise transfer. The setting of the multi-angle transfer arm 410 makes the assembly machine applicable not only to flat screens but also to the assembly of curved screens. In the attachment process of the backlight panel and the panel, it can significantly improve the attachment effect. At the same time, through the cooperation of the multi-angle transfer arm 410 and the backlight panel loading component 430, the degree of automation of the assembly process is high, and the production efficiency is significantly improved.

[0069] It should be noted that although the specific use process of the multi-angle transfer arm 410 in this article is explained by taking a curved screen as an example; however, from its structure, it can be seen that the present invention is not only applicable to the assembly process of curved screens, but also applicable to flat panel screens.

[0070] Preferably, the assembly mechanism 400 includes a first multi-angle transfer arm 410a and a second multi-angle transfer arm 410b slidably connected to the bracket 420; and a pressure-holding surface 470 is provided below one end of the bracket 420 away from the panel loading station; the first multi-angle transfer arm 410a alternately moves between the panel loading station and the backlight board loading assembly 430; the second multi-angle transfer arm 410b alternately moves above the backlight board loading assembly 430 and the pressure-holding surface 470 through the bracket 420.

[0071] In use, the first multi-angle transfer arm 410a is used to grab the panel from the panel loading station and move it above the backlight board loading assembly 430 for the fitting and assembly process; the second multi-angle transfer arm 410b cooperates with the pressure-holding surface 470 to grab the panel assembled by fitting and transfer it to the pressure-holding surface 470 for pressing (i.e., the pressure-holding process), so that the two are assembled more firmly;

[0072] Among them, the second multi-angle transfer arm 410b has the same structure as the first multi-angle transfer arm 410a. Similarly, its first rotation assembly 4121 is used to drive the fixture 411 to rotate longitudinally (i.e., rotate around the Y axis) to adjust the panel angle; in the pressure-holding process, it can make the two adhere closely, and the adhesion effect is significantly improved.

[0073] The second multi-angle transfer arm 410b can drive the panel to adjust its position in multiple directions and accurately position it at the working station, achieving the effect of precise transfer; in the pressure-holding process, the setting of the second multi-angle transfer arm 410b makes it applicable not only to flat screens but also to the pressure-holding operation of curved screens, and it can significantly improve the adhesion effect between the backlight board and the panel; and by setting the double multi-angle transfer arms 410, the assembly process and the pressure-holding process can be carried out simultaneously, significantly improving the production efficiency.

It should be noted that: the adsorption mechanism is an existing adsorption device, and those skilled in the art can adaptively select from the existing adsorption devices according to the above design concept, including but not limited to the above solutions.

[0076] More preferably, a plurality of adsorption mechanisms are detachably connected to the jig 411. Among them, detachably connecting the adsorption mechanism to the jig 411 facilitates the disassembly, replacement and maintenance of the adsorption mechanism and is convenient to use. More preferably, the relative position between the adsorption mechanism and the jig 411 is adjustable. Setting the relative position between the adsorption mechanism and the jig 411 to be adjustable enables the adsorption mechanism to be position-adjusted according to the shape and size of the panel to be transferred as needed, which is convenient and practical;

[0077] Preferably, the first rotation assembly 4121 is detachably connected to the top end of the jig 411. Due to the change of the size specification and shape of the face screen, it is necessary to replace the jig 411 during use, such as Figures 1-18 As shown, multiple jigs 411 are shown in this embodiment. Setting the first rotation assembly 4121 to be detachably connected to the top end of the jig 411 facilitates the disassembly, replacement and maintenance of the jig 411.

More preferably, a conveyor belt assembly (such as a CV roller conveyor) is provided below the film tearing mechanism 300.

[0079] Before assembly, some panels will be covered with a film. By setting the film tearing mechanism 300 to tear off the film on the panel before assembly, it is convenient for the assembly process; among them, the first multi-angle transfer arm 410a alternately moves along the bracket 420 above the panel loading station, above the film tearing mechanism 300, and above the backlight board loading component 430 in sequence, so as to transfer the panel to the backlight board loading component 430 for assembly after the film tearing process in sequence.

[0080] Preferably, the film tearing mechanism 300 includes a roller assembly 310 and a first multi-directional movement mechanism; the roller assembly 310 is used to stick to and tear off the film on the panel; the first multi-directional movement mechanism includes a film tearing Y-axis movement assembly 320, a film tearing Z-axis movement assembly 330 and the roller assembly 310; the roller assembly 310 is installed on the film tearing Z-axis movement assembly 330, and the film tearing Z-axis movement assembly 330 is connected to the film tearing Y-axis movement assembly 320, so that the multi-directional movement mechanism drives the roller assembly 310 to move.

[0082] As Figures 1-18 shown, during use, the film tearing Y-axis movement assembly 320 and the film tearing Z-axis movement assembly 330 can drive the roller assembly 310 to move, and the roller assembly 310 can move in multiple directions and accurately locate to the required position. At the same time, with such a setting, the movement of the roller assembly 310 is automated, which can reduce the number of operators and improve production efficiency.

[0083] It should be noted that in this embodiment, the roller assembly 310 with a film tearing function having the above structure is used for the film tearing process; the roller assembly 310 is an existing device, and those skilled in the art can make adaptive selections according to actual needs based on the above design concept, including but not limited to the embodiment solutions.

[0084] Preferably, a cleaning component 450 and a backlight foreign object detection component 460 are sequentially arranged above the backlight panel feeding component 430 along the transmission direction of the backlight panel; the cleaning component 450 is used to clean the backlight panel on the backlight panel feeding component 430, and the backlight foreign object detection component 460 is used to detect whether there are foreign objects on the cleaned backlight panel.

[0085] The cleaning component 450 is provided to clean the backlight panel on the backlight panel feeding component 430 to improve the cleanliness of the backlight panel, thereby improving the assembly quality of the backlight panel and the panel; similarly, the backlight foreign object detection component 460 is provided to detect whether there are foreign objects on the cleaned backlight panel to ensure the cleanliness of the backlight panel, thereby improving the assembly quality of the backlight panel and the panel.

[0086] It should be noted that the cleaning component 450 and the backlight foreign object detection component 460 are existing devices, and their structures and working principles will not be elaborated here; those skilled in the art can make adaptive selections according to actual needs based on the above design concept.

[0087] Preferably, a backlight panel position adjusting assembly 431 is provided on the backlight panel loading assembly 430. The backlight panel position adjusting assembly 431 is used to install the backlight panel. The backlight panel position adjusting assembly 431 is installed on the backlight panel loading assembly 430 to move along the Y-axis on the backlight panel loading assembly 430. Among them, the relative position between the backlight panel and the backlight panel position adjusting assembly 431 can be adjusted.

[0088] In this embodiment, the backlight panel position adjusting assembly 431 includes an outer frame body and several cross bars connected to the outer frame body at both ends.

[0089] It should be noted that the backlight panel position adjusting assembly 431 of this embodiment has the functions of adjusting the horizontal and vertical (i.e., X-axis and Y-axis) orientations. According to the above design concept, those skilled in the art can adopt other structures of the backlight panel position adjusting assembly 431 to make it have the functions of adjusting the horizontal and vertical orientations, including but not limited to the embodiment scheme.

[0090] Preferably, a feeding mechanism 100 and a panel edge inspection mechanism 200 are provided at the front end of the panel loading station. The panel edge inspection mechanism 200 includes a panel edge inspection arm 210, a panel edge detection assembly 220, and a feeding port 230 connecting the feeding mechanism 100 and the panel edge detection assembly 220. The panel edge inspection arm 210 includes an arm for grasping the panel and a second multi-directional movement mechanism. The second multi-directional movement mechanism is connected to the arm to drive the arm to rotate vertically so as to reverse the orientation of the panel on the arm.

Among them, the feeding mechanism 100 can adopt a tray.

[0091] The panel edge detection assembly 220 is provided with a third multi-directional movement mechanism to drive the panel edge detection component 221 to move and adjust the position. In use, the feeding mechanism 100 is used for panel feeding. To check the quality of the panel, a panel edge inspection mechanism 200 is provided to perform edge inspection on the panel after feeding. The specific process is as follows:

[0092] The arm of the border inspection arm 210 grabs the panel, and the third multi-directional motion mechanism of the border inspection component 220 drives the border inspection component 221 to move along one side edge (for example, the long side) of the panel, thereby performing border inspection on the long side; then the arm of the border inspection arm 210 drives the panel to turn 90 degrees, and the third multi-directional motion mechanism drives the border inspection component 221 to move along the other side edge (for example, the wide side) of the panel, thereby performing border inspection on the wide side, thus completing the border inspection of the panel.

Preferably, the border inspection component 221 also includes a camera light source assembly 2213 for providing light to the border inspection camera 2211.

[0096] During border inspection, two relatively arranged border inspection cameras 2211 synchronously inspect two opposite sides of the panel (two opposite long sides or two opposite wide sides). By setting a third driving mechanism to drive the border inspection cameras 2211 to move along the movable slide rail 2212, the relative distance between the two border inspection cameras 2211 can be adjusted, thereby adapting to the inspection of two opposite long sides or two opposite wide sides at the same time, and it can be suitable for border inspection of panels of multiple sizes.
