Description

Technical Field

[0001] This utility model relates to the field of coating, and more specifically, to an OLED screen module colloidal coating device. Background Technology

[0002] The application of OLED screen module colloidal coating equipment in display technology is becoming increasingly widespread, mainly due to the vibrant colors, high contrast, and flexibility of OLED (Organic Light Emitting Diode) displays, which are favored by the consumer electronics industry. Meanwhile, effective colloidal coating technology is a crucial step in ensuring high-quality OLED screen production.

[0003] A search revealed that Chinese Patent Publication No. CN222705524U discloses "A Dry Powder Coating Device for Electrodes," comprising a heating roller, a first powder coating device, a second powder coating device, a first heating device, and a second heating device. The first powder coating device is located on one side of the current collector and is used to feed a first mixture of powders. The second powder coating device is located on the other side of the current collector and is used to feed a second mixture of powders. The first heating device is located on the inner wall of the heating roller and is used to heat the first mixture of powders. The second heating device is located on one side of the outer wall of the heating roller and is used to heat the second mixture of powders. A first conductive adhesive is provided on one side of the current collector, and a second conductive adhesive is provided on the other side. This invention has the advantages of simple coating process, strong adhesion between the electrode layer and the current collector, and the ability to achieve simultaneous double-sided electrode coating. However, it still has the following drawbacks: (1) When using the above application, it is difficult to automatically unload the coated screen after the coating is completed, so that manual handling is required afterward. (2) In the above application, it is difficult to fix the coated screen during the coating process, which causes the screen to shift during coating. To address this, an OLED screen module colloid coating device is proposed. Utility Model Content

The driving device includes a motor, the top of which is fixedly connected to the bottom of the support frame. A threaded rotating rod is fixedly connected to the output shaft of the motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rotating rod. A connecting strip is fixedly connected to the circumferential surface of the threaded sleeve. The top of the coating device is fixedly connected to the bottom of the connecting strip. A drive gear is fixedly connected to the bottom of the threaded rotating rod. A rack is slidably connected to the top of the worktable. The drive gear meshes with the side of the rack. The meshing of the drive gear and the side of the rack is to push the rack to move when the drive gear rotates. A support rod is fixedly connected to the top of the rack. A push plate is fixedly connected to the front side of the support rod. A limit rod is fixedly connected to the bottom of the motor. The circumferential surface of the limit rod slides through a limit hole in the side wall of the threaded sleeve. The bottom of the push plate is located above the coating table. The limit rod restricts the movement trajectory of the threaded sleeve when it moves. The rack moves by driving the push plate through the support rod.

[0006] As a preferred technical solution of this utility model, the coating device includes a telescopic rod, the top of which is fixedly connected to an extension rod at the top of the support frame, and a fixed plate is fixedly connected to the bottom of the telescopic rod. A micro screw is provided at the bottom of the fixed plate, and a moving block is helically connected to the circumferential surface of the micro screw. A coater is provided at the bottom of the moving block. The telescopic rod is used to drive the coater to move, and the coater is used to apply adhesive to the screen.

[0007] As a preferred technical solution of this utility model, a fixing device is provided on the top of the workbench. The fixing device includes a through groove, a rotating shaft is fixedly connected to the inner wall of the through groove, a force-bearing plate is rotatably connected to the circumferential surface of the rotating shaft, a roller is rotatably connected to the inner wall of the force-bearing plate, a connecting shaft is fixedly connected to the inner wall of the force-bearing plate, a fixing block is rotatably connected to the circumferential surface of the connecting shaft, a rubber pad is fixedly connected to the bottom of the fixing block, a drive gear is rotatably connected to the top of the workbench, a threaded rod is fixedly connected to the bottom of the drive gear, the bottom of the threaded rod is rotatably connected to the top of the support leg, a threaded block is threadedly connected to the circumferential surface of the threaded rod, a fixing rod is fixedly connected to the circumferential surface of the threaded block, and a pressing block is fixedly connected to the top of the fixing rod. The rubber pad is used to prevent damage to the screen during fixing.

[0008] As a preferred technical solution of this utility model, a torsion spring is fixedly connected to the circumferential surface of the rotating shaft, and the end of the torsion spring away from the rotating shaft is fixedly connected to the side of the force plate. A limit shaft is fixedly connected to the bottom of the worktable, and the circumferential surface of the limit shaft slides through the limit hole in the side wall of the threaded block. The function of the limit shaft is to limit the movement trajectory of the threaded block when it moves.

[0009] As a preferred technical solution of this utility model, the active gear meshes with the driving gear, the circumferential surface of the roller is located on the displacement trajectory of the extrusion block, and the number of the through slot, rotating shaft, force plate, roller, connecting shaft, fixing block, rubber pad and torsion spring are each set to two, and they are symmetrical to each other along the vertical central axis of the worktable. The function of the active gear meshing with the driving gear is to drive the driving gear to rotate when the active gear rotates. The function of setting two through slots, rotating shaft, force plate, roller, connecting shaft, fixing block, rubber pad and torsion spring is to better fix the screen.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The drive device is designed so that when the connecting bar moves downward, the telescopic rod can drive the coating device to move downward to coat the screen. When the threaded rod reverses, it can drive the drive gear to reverse. When the drive gear reverses, it can push the rack forward. When the rack moves forward, it can drive the push plate to move through the support rod. When the push plate moves, it can push the screen coated on the coating table off the coating table, thus completing the screen unloading. 2. The fixing device ensures that as the extrusion block moves upward, it rotates the force plate via two rollers and a rotating shaft. When the force plate rotates, it drives the fixing block to rotate via a connecting shaft. This rotation of the fixing block, in turn, drives the rubber pad to rotate, thereby fixing the screen on the coating table and preventing displacement of the screen during coating. The rubber pad also prevents the fixing block from directly fixing the screen and causing damage. Attached Figure Description

[0021] like Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, in a preferred embodiment, based on the above method, a torsion spring 713 is fixedly connected to the circumferential surface of the rotating shaft 72. The end of the torsion spring 713 away from the rotating shaft 72 is fixedly connected to the side of the force plate 73. A limiting shaft 714 is fixedly connected to the bottom of the worktable 1. A limiting hole with vertical penetration is provided on the side wall of the threaded block 710. The limiting shaft 714 slides through the limiting hole. The function of the limiting shaft 714 is to limit the movement trajectory of the threaded block 710 when it moves.

[0022] like Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, in a preferred embodiment, based on the above method, the driving gear 65 meshes with the drive gear 78, the circumferential surface of the roller 74 is located on the displacement trajectory of the extrusion block 712, and the number of through slots 71, rotating shafts 72, force plates 73, rollers 74, connecting shafts 75, fixing blocks 76, rubber pads 77 and torsion springs 713 are each set to two, and are symmetrical to each other along the vertical central axis of the worktable 1. The function of the driving gear 65 meshing with the drive gear 78 is to drive the drive gear 78 to rotate when the driving gear 65 rotates.

[0023] Specifically, when using this coating drive device: First, when it is necessary to use this device to coat a screen, the drive device 6 can be used. The screen is placed on the coating table 4, and then the motor 61 is started. When the output shaft of the motor 61 rotates, it drives the threaded rotating rod 62 to rotate. At this time, the drive gear 65 rotates, which in turn drives the rack 66 to move backward. When the threaded rotating rod 62 rotates, it drives the threaded sleeve 63 to move downward. When the threaded sleeve 63 moves downward, it drives the connecting strip 64 to move downward. Thus, when the connecting strip 64... 4. When moving downwards, the telescopic rod 51 can be used to drive the coater 55 to move downwards to coat the screen. After the coating is completed, the output shaft of the motor 61 can reverse to drive the threaded rotating rod 62 to reverse. When the threaded rotating rod 62 reverses, it can drive the drive gear 65 to reverse. When the drive gear 65 reverses, it can push the rack 66 forward. When the rack 66 moves forward, it can drive the push plate 68 to move through the support rod 67. When the push plate 68 moves, it can push the screen that has been coated on the coating table 4 off the coating table 4, thus completing the screen unloading. The rotation of the drive gear 65 drives the fixed device 7, which is shown in its initial state in the figure. When the drive gear 65 rotates, it drives the drive gear 78 to rotate through meshing. When the drive gear 78 rotates, it drives the threaded rod 79 to rotate. When the threaded rod 79 rotates, it drives the threaded block 710 to move upward. When the threaded block 710 moves upward, it drives the pressing block 712 to move upward through the fixed rod 711. Thus, when the pressing block 712 moves upward, it can contact the roller 74 with its inclined surface, thereby pressing the pressing block 712... As 12 continues to move upward, the force plate 73 will rotate via two rollers 74 and a rotating shaft 72 (the inclined length of the extrusion block 712 is sufficient to ensure that the force plate 73 rotates to the top or that the rollers 74 do not detach from the inclined surface). When the force plate 73 rotates, it can drive the fixing block 76 to rotate via the connecting shaft 75. Thus, when the fixing block 76 rotates, it can drive the rubber pad 77 to rotate, thereby fixing the screen on the coating table 4 and preventing the screen from shifting during coating. The setting of the rubber pad 77 prevents the fixing block 76 from directly fixing the screen and causing damage to the screen.

[0024] All technical features in this embodiment can be freely combined according to actual needs.

[0025] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
