DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 7 The figure shows an OLED device packaging device, including a packaging box 1, the top and bottom of the packaging box 1 are fixedly connected with a conveying channel 3, and the two sets of conveying channels 3 are provided with a liftable adsorption mechanism 8 inside. The movable end of the adsorption mechanism 8 is in sliding and sealing cooperation with the conveying channel 3; It also includes a feeding mechanism 5 arranged at the top and bottom of the packaging box 1. The two groups of feeding mechanisms 5 are loaded with the cover plate and the substrate respectively. The outer surface of the conveying channel 3 is provided with an inlet 4. The feeding mechanism 5 moves into the conveying channel 3 through the inlet 4 to convey the cover plate and the substrate into the conveying channel 3. After the cover plate and the substrate are adsorbed by the adsorption mechanism 8, the feeding mechanism 5 exits from the conveying channel 3 through the inlet 4. The outer surface of the conveying channel 3 located below is provided with an outlet 9.

[0020] In this embodiment, the cover plate and the substrate are placed in two groups of feeding mechanisms 5 respectively. The feeding mechanism 5 feeds the cover plate and the substrate into the corresponding conveying channel 3 through the feed port 4. After the cover plate and the substrate are adsorbed and fixed by the adsorption mechanism 8 inside the conveying channel 3, the feeding mechanism 5 exits the conveying channel 3 through the feed port 4, and space is reserved so that the cover plate and the substrate inside the two groups of conveying channels 3 are close to each other.

[0021] Furthermore, the feeding mechanism 5 includes a feeding seat 51, which is set to be U-shaped, and a slot is provided on the inner surface of the open end of the feeding seat 51. A slider 53 is fixedly connected to the outer surface of the feeding seat 51, and a slide groove 52 adapted to the slider 53 is provided on the outer surface of the packaging box 1. A first electric push rod 54 is fixedly installed inside the slide groove 52, and the telescopic end of the first electric push rod 54 is fixedly connected to the slider 53, and the slider 53 is slidably installed inside the slide groove 52.

[0022] Furthermore, the interior of the feeding seat 51 is configured to be hollow, and a screw rod 58 is rotatably connected to the interior of the feeding seat 51. A first motor 57 is fixedly installed inside the feeding seat 51. The output shaft of the first motor 57 is fixedly connected to one end of the screw rod 58. The threads on both sides of the screw rod 58 rotate in opposite directions, and ball seats 59 are sleeved on both sides of the outer surface of the screw rod 58. Second electric push rods 510 are fixedly connected to both sides of the ball seats 59. The telescopic ends of the second electric push rods 510 are fixedly connected to moving blocks 56. Moving grooves 55 are opened on both sides of the feeding seat 51, and the moving blocks 56 are slidably installed inside the moving grooves 55.

[0023] In this embodiment, the ball screw is an existing transmission element, and its main function is to convert rotational motion into linear motion. It will not be described in detail here. In actual use, it is necessary to connect the first motor 57 to an external power supply and drive the first motor 57 forward and reverse. The ball seat 59 can move along the screw rod 58. Since the threads on both sides of the screw rod 58 rotate in opposite directions, when the first motor 57 rotates forward and reverse, the two groups of ball seats 59 approach or move away from each other.

[0024] In this embodiment, the cover plate and the substrate can be inserted into the feeding seat 51 through the slots, and since the two sides of the cover plate and the substrate are embedded in the slots, the substrate can be stably suspended inside the inverted feeding seat 51 below; in addition, by driving the second electric push rod 510 to extend, the two sets of moving blocks 56 are extended into the feeding seat 51 and located at both ends of the substrate or the cover plate, and then the first motor 57 is used to drive the screw rod 58 to rotate forward, driving the two sets of ball seats 59 and the moving blocks 56 to approach each other. When the two sets of moving blocks 56 approach each other, the substrate and the cover plate can be pushed to the middle of the feeding seat 51, so that the substrate and the cover plate remain aligned, and then the first electric push rod 54 is driven to move, driving the feeding seat 51, the substrate and the cover plate to move into the conveying channel 3. After the substrate and the cover plate are adsorbed and fixed by the adsorption mechanism 8, the second electric push rod 510 is first driven to retract, driving the moving block 56 to move into the moving groove 55, and then the first electric push rod 51 is driven to retract, driving the feeding seat 51 to move out of the conveying channel 3.

[0025] Furthermore, it also includes a storage mechanism 6 arranged on the upper and lower surfaces of the packaging box 1. The storage mechanism 6 includes a turntable 61 rotatably installed on the surface of the packaging box 1. The packaging box 1 is provided with a rotating mechanism 7. The rotating mechanism 7 can drive the two sets of turntables 61 to rotate synchronously. A plurality of storage slots 62 are provided on the surface of the turntable 61.

[0026] In this embodiment, the storage trough 62 is used to place the cover plate and substrate to be packaged. The rotating mechanism 7 is used to drive one group of storage troughs 62 to align with the feeding seat 51, and then the pushing piece can be used to push the cover plate or substrate inside the storage trough 62 into the feeding seat 51, so that automatic loading can be achieved.

[0027] Furthermore, the pushing member includes a third electric push rod 65 fixedly installed at the center of the outer surface of the turntable 61. The inner center of the turntable 61 is hollow, and a first airbag 66 is provided at the inner center of the turntable 61. The telescopic end of the third electric push rod 65 is fixedly connected to one end of the first airbag 66. The inner surface of the material storage trough 62 is provided with a push groove 63. A push plate 64 is slidably installed inside the push groove 63. One side of the push plate 64 is located inside the material storage trough 62, and the other side of the push plate 64 is located inside the push groove 63 and is fixedly connected to the second airbag 67. The other side of the second airbag 67 is fixedly connected to the inner surface of the push groove 63. A connecting pipe 68 is fixedly connected between the second airbag 67 and the first airbag 66, and a control valve 69 is provided on the connecting pipe 68.

[0028] Furthermore, the first airbag 66 and the second airbag 67 are both elastic bags. When the second airbag 67 is in a natural state, the push plate 64 is away from the opening end of the material storage trough 62.

[0030] In this embodiment, the control valve 69 can be any existing type of solenoid valve to meet the simple pipeline on-off control function, and the control valve 69 is used in conjunction with the control. When the storage trough 62 is aligned with the feeding seat 51, the controller makes the control valve 69 corresponding to the storage trough 62 open, and the remaining control valves 69 are all closed. At this time, the third electric push rod 65 is driven to extend and compress the first airbag 66. The gas in the first airbag 66 can enter the corresponding second airbag 67 through the connecting pipe 68. The second airbag 67 extends to drive the push plate 64 to move, and the push plate 64 can push the substrate or cover plate in the storage trough 62 into the feeding seat 51.

[0031] It should be noted that: in actual application, the controller can achieve precise control of the control valve 69 through programming to ensure the switching of the control valve 69. This is an existing conventional technology and will not be described in detail here.

[0032] Furthermore, the rotating mechanism 7 includes a mounting groove 72 opened on one side of the outer surface of the packaging box 1, and a first transmission wheel 73 is rotatably connected inside the mounting groove 72.

The output shaft of the second motor 77 is fixedly connected to the second transmission wheel 75. The outer surfaces of the first transmission wheel 73 and the second transmission wheel 75 are jointly covered with a conveyor belt 74.

[0033] In this embodiment, by driving the second motor 77 to rotate, the second transmission wheel 75, the conveyor belt 74 and the first transmission wheel 73 are driven to rotate, thereby driving the rotating shaft 71 and the two sets of turntables 61 to rotate, so that the relative position of the turntable 61 and the feeding seat 51 can be adjusted to align different storage slots 62 with the feeding seat 51.
