Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0058] In the figures, structurally similar elements are denoted by the same reference numerals.

[0059] The terms "first", "second", etc. in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, and should not be used as a limitation on the order of precedence.

[0060] Please combine Figure 1 The following is a detailed description of a preferred embodiment of a back glue and frame glue integrated machine provided by the present invention that can solve the above technical problems:

[0061] A back glue and frame glue integrated machine is used to stick back glue and frame glue to a display module. The back glue and frame glue integrated machine includes: an equipment frame 1, a loading and unloading system 2, a first sticking device 3, a film tearing device 4 and a second sticking device 5. The loading and unloading system 2 is located on the equipment frame 1, and is used to load and unload the display module, and includes: a loading unit 21, an unloading unit 24 and a scheduling unit 26. The loading unit 21 is located at one end of the equipment frame 1, and is used to load the display module. The structure of the unloading unit 24 is the same as that of the loading unit 21. The unloading unit 24 is located at the other end of the equipment frame 1, and is used to unload the display module. The scheduling unit 26 is located on the equipment frame 1. The first sticking device 3 is located on the equipment frame 1 and is located between the loading and unloading system 2, and is used to stick back glue. The film tearing device 4 is located on the equipment frame 1, and is located on the side of the first sticking device 3 away from the loading unit 21, and is used to tear off the film on the display module. The second pasting device 5 is located on the equipment frame 1 and between the film tearing device 4 and the unloading unit 24, and is used for pasting the frame glue or the back glue. Among them, the scheduling unit 26 is located on the equipment frame 1, one end of which is connected to the loading unit 21, and the other end is connected to the unloading unit 24, and is used to transport the display module located on the loading unit 21 to the first pasting device 3 and the second pasting device 5 for gluing, and to transport the display module after gluing by the first pasting device 3 and the second pasting device 5 to the unloading unit 24. In this embodiment, the scheduling unit 26 includes three handling manipulators.

[0062] The adhesive-frame glue integrated machine of this embodiment is provided with a first pasting device 3 and a second pasting device 5 in the adhesive-frame glue integrated machine. When it is necessary to paste the glue, the second pasting device 5 can paste the glue to the display module that has been pasted with the adhesive in the first pasting device 3; when it is not necessary to paste the glue, the second pasting device 5 can be directly used as the adhesive pasting device to paste the adhesive at the same time as the first pasting device 3. The adhesive-frame glue integrated machine of the present invention has more diversified overall functions, is easy to operate, and improves production efficiency. It solves the problem that most of the adhesive-frame glue integrated machines in the prior art have unreasonable structural designs, and the display module needs to replace the equipment to paste the glue after the adhesive is pasted, and the operation is cumbersome, and the function of each device is single, and the work efficiency is low.

[0063] Please combine Figure 2 , the loading and unloading system 2 in the present invention is described in detail as follows:

[0064] The loading unit 21 includes: a first lifting mechanism 22, a second lifting mechanism 23 and a grabbing assembly 24. The first lifting mechanism 22 is located on the equipment frame 1, and is used to transport the material tray containing the display module. The second lifting mechanism 23 is located on the equipment frame 1, and is used to unload multiple empty material trays one by one. The grabbing assembly 24 is located on the equipment frame 1, and is used to grab the material tray and the display module. The first lifting mechanism 22 and the second lifting mechanism 23 can accommodate multiple layers of material trays. When the first lifting mechanism 22 is raised by one unit height, the second lifting mechanism 23 is lowered by one unit height.

The transverse gripping portion is connected to the longitudinal gripping assembly 24 for transversely gripping the material tray. The provision of the transverse gripping portion is conducive to the third manipulator 33 to grip the material tray more stably. In this embodiment, the first manipulator 241 and the second manipulator 242 share a manipulator body 2421.

[0068] Please combine Figure 3 , the second manipulator 242 of the present invention is described in detail as follows:

[0069] The longitudinal grasping part includes: a main rod 2422a, a secondary rod 2422b, a connecting piece 2422c and a second grasping hand 2422d. A first strip groove is provided on the main rod 2422a. The secondary rod 2422b is located at both ends of the main rod 2422a, and is provided with fixing holes, and is bolted to the main rod 2422a. The extension direction of the secondary rod 2422b is perpendicular to the extension direction of the main rod 2422a. The connecting piece 2422c is located at both ends of the secondary rod 2422b, and is bolted to the secondary rod 2422b, and is provided with a second strip groove. The second grasping hand 2422d is connected to the connecting piece 2422c for grasping the material tray. The provision of the strip groove can change the relative position relationship between the secondary plate and the main plate and the relative position relationship between the connecting piece 2422c and the secondary plate, so that the longitudinal grasping part can grasp pallets of more specifications, thereby improving the applicability of the longitudinal grasping part.

[0070] In addition, the second gripper 2422d is provided with a telescopic column, which is located in the middle of the second gripper 2422d, and is used to reduce the impact of the second gripper 2422d on the tray. The setting of the telescopic column is conducive to protecting the tray, and preventing the tray from being deformed by excessive stamping of the third tray manipulator 33, which affects subsequent use.

[0071] The transverse grasping part in this embodiment includes: a first plate 2423a, a second plate 2423b and a hook 2423c.

Then the first manipulator 241 rotates a certain angle to grab the display module according to the position of the display module. Ensure that the first manipulator 241 can accurately grab the display module.

[0073] In addition, the loading unit 21 also includes a beam fiber assembly 29. The beam fiber assembly 29 is located on the equipment frame 1 and at both ends of the first lifting mechanism 22, and is used to detect the position of the material tray. When the beam fiber assembly 29 detects that the material tray is at the specified loading position, the first manipulator 241 starts to unload the display module.

[0074] In this embodiment, the loading unit 21 further includes a conveying assembly 20, which is located on the equipment frame 1 and is used to receive and convey the display module. Figure 4 , the conveying assembly 20 in this embodiment is described in detail as follows:

[0079] Please combine Figure 7 The adhesive supply unit 32 of the present invention is described in detail as follows:

[0080] The adhesive supply unit 32 includes: a fixed plate 321, an adhesive peeling platform 3222 assembly and an adhesive tape winding assembly. The fixed plate 321 is fixedly connected to the equipment frame 1 and is arranged perpendicular to the equipment frame 1. The adhesive peeling platform 3222 assembly is movably connected to the fixed plate 321 and is arranged perpendicular to the fixed plate 321 and parallel to the plane of the equipment frame 1. The adhesive tape is wound on the roller of the tape winding assembly. The tape winding assembly keeps the adhesive tape in tension. The tape winding assembly is used to spread one section of the adhesive tape onto the adhesive peeling platform 3222 assembly. The adhesive peeling platform 3222 assembly moves on the fixed plate 321 and produces relative displacement with the adhesive tape.

[0081] The glue peeling platform 3222 assembly includes: a connecting plate 3221, a glue peeling platform 3222 and an auxiliary wheel 3223.

The glue peeling platform 3222 is connected to the connecting plate 3221 and is arranged perpendicular to the connecting plate 3221 for carrying the adhesive-backed film. The auxiliary wheel 3223 is connected to the connecting plate 3221 and is located below the glue peeling platform 3222. The axial direction of the auxiliary wheel 3223 is perpendicular to the fixed plate 321.

[0082] The tape winding assembly includes: a feeding roller 3231, a recovery roller 3232 and a guide roller group 3233. The feeding roller 3231 is connected to the fixed plate 321 and is used to place the adhesive film roll. A permanent magnetic brake is provided on one side of the feeding roller 3231, and the permanent magnetic brake is used to drive the feeding roller 3231 to rotate. The recovery roller 3232 is connected to the fixed plate 321, located below the feeding roller 3231, and is used to recover the adhesive film roll. The guide roller group 3233 is connected to the fixed plate 321. The guide roller group 3233 is located between the feeding roller 3231 and the recovery roller 3232, and is used to guide the adhesive film roll to be wound on the adhesive peeling platform 3222. If the robot directly peels off the adhesive, it will cause the adhesive to wrinkle or even be damaged. Therefore, the adhesive peeling platform 3222 assembly is used to replace the robot to peel off the adhesive, which can avoid wrinkles or damage to the adhesive and obtain a complete adhesive. The utilization rate of the adhesive is improved. The adhesive peeling platform 3222 moves forward and backward driven by the connecting plate 3221 to peel off the adhesive.
