Description

Technical Field

[0001] The present invention relates to a screen packaging device, in particular to a screen packaging device for processing an LED touch display screen, and belongs to the technical field of touch display screen processing. Background Art

[0002] LED touch screens combine LED display and touch technology. LEDs emit light through the recombination of electrons and holes, and different colored LED combinations present colorful images. Touch mostly uses infrared technology, relying on an infrared detection network to determine the touch point. It has excellent display effects and a wide range of applications. It plays an important role in commercial product display, interactive teaching in education and training, information release in public places, smart home control and entertainment, and industrial control. During the display processing, the screen needs to be encapsulated into the inside of the shell through packaging equipment.

[0003] In the prior art, the utility model with application number CN202322714025.5 discloses a screen packaging device. In order to solve the problem that traditional equipment requires manual loading, which reduces the packaging efficiency, the device uses the setting of conveying the shell and the screen to automatically load the material, thereby improving the packaging efficiency. The device pushes out and conveys the packaged screen to automatically unload the material, further improving the packaging efficiency. The setting of limiting the conveying improves the accuracy of the packaging pressing.

[0004] Similar to the above application, there are still some deficiencies:

[0005] During the packaging process, it is necessary to first use a suction cup to clamp the display screen, then control the suction cup and the display screen to rise to a high position, and then control the horizontal movement of the display screen to transfer the position of the display screen. Finally, when the display screen is pressed into the inside of the shell, the entire packaging process requires an electric push rod to control the suction cup assembly to perform two lifting operations. The processing rate is low, and the lifting and translation require different control devices to control. In order to perform joint control, a complex control system is required, and the production and use costs of the device are high.

[0006] Therefore, a screen packaging device for LED touch display processing is designed to optimize the above problems. Summary of the Invention

[0007] The main purpose of the present invention is to provide a screen packaging device for processing LED touch display screens, which controls the up and down movement of the suction cup fixing mechanism on the frame through a second electric telescopic rod, and in the process of the suction cup moving up and down, uses the lifting mechanism to control the screen on the top of the carrier plate to move up to complete the adsorption and fixation of the screen, and then uses the rotation mechanism to control the suction cup fixing mechanism and the screen to rotate ninety degrees while controlling the suction cup fixing mechanism to continue to move down, and transfer it to the top of the shell, and continue to move down to complete the packaging of the screen. The entire packaging process only requires the use of the second electric telescopic rod to control the suction cup fixing mechanism for a single lifting and lowering, which speeds up the packaging rate. At the same time, a mechanical transmission method is used to complete the upward transportation and rotational displacement of the screen, replacing the complex transmission control system part, reducing the production and use costs of the device.

After the screen is adsorbed and fixed, the first rack is separated from the first gear, and the second rack is quickly reset under the action of the return spring, without affecting the suction cup fixing mechanism and the continued downward movement of the screen, making the adsorption and fixing of the screen more convenient. The rotating mechanism composed of the third rack, the support rod, the second gear, the worm, the support plate, the worm gear, the sliding hole, the vertical groove, and the slider can automatically engage with the second gear after the screen is adsorbed and fixed by the suction cup fixing mechanism, controlling the downward movement of the screen while controlling the screen to automatically rotate to the top of the shell.

[0040] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0041] like Figures 1-8 As shown, this embodiment provides a screen packaging device for processing an LED touch display screen, including a frame 1, a shell conveying mechanism 2 is provided at the bottom of the frame 1, and a screen conveying mechanism 3 is vertically provided on the side of the shell conveying mechanism 2, the screen conveying mechanism 3 is higher than the horizontal plane of the top of the shell conveying mechanism 2, and a second electric telescopic rod 6 is vertically installed on the top of the frame 1, and a mounting plate 7 is installed at the output end of the second electric telescopic rod 6. A shaft rod 8 is rotatably installed at the bottom of the mounting plate 7, and a cross bar 9 is fixed to the bottom end of the shaft rod 8. A suction cup fixing mechanism 10 is provided at the end of the cross bar 9 away from the shaft rod 8, and a rotating mechanism 11 is provided on the inner side of the frame 1 for controlling the shaft rod 8 to rotate ninety degrees as the mounting plate 7 moves vertically, a carrier plate 4 is horizontally provided on the end of the screen conveying mechanism 3 close to the shell conveying mechanism 2, and a lifting mechanism 5 is provided on the top of the frame 1 for controlling the up and down movement of the carrier plate 4 as the mounting plate 7 moves vertically.

[0042] The overall working principle is as follows: when packaging the screen, the screen is placed on the screen conveying mechanism 3 for horizontal conveyance, and the shell is placed on the shell conveying mechanism 2 for linear conveyance. The shell is perpendicular to the conveying direction of the screen, and the conveying height of the screen is higher than the conveying height of the shell. When the screen is conveyed linearly, the screen is first conveyed to the top of the carrier plate 4, and the initial position of the suction cup fixing mechanism 10 is located at the top of the carrier plate 4. Then, the second electric telescopic rod 6 is started to control the suction cup fixing mechanism 10 to move downward, and at the same time, the lifting mechanism 5 is used to control the screen on the top of the carrier plate 4 to move up and contact with the bottom of the suction cup fixing mechanism 10, using negative pressure. The screen is fixed by adsorption. After the screen is adsorbed and fixed, as the suction cup fixing mechanism 10 continues to move, the lifting mechanism 5 rises to the highest position and quickly moves downward to avoid interfering with the downward movement of the suction cup fixing mechanism 10. When the suction cup fixing mechanism 10 drives the screen to continue to move downward, the rotation mechanism 11 is used to control the suction cup fixing mechanism 10 and the screen to rotate ninety degrees to the top of the shell conveying mechanism 2. At this time, the shell is facing the bottom of the screen and continues to control the downward movement of the screen. At this time, the screen only moves vertically and engages with the shell to complete the packaging of the screen, and then the control device is reset.

[0043] In this embodiment, the suction cup fixing mechanism 10 includes a negative pressure pump 1001, an upper plate 1002, a lower plate 1003, a buffer spring 1004, a second sliding rod 1005 and a suction cup 1006. The negative pressure pump 1001 is installed at the top of the cross bar 9, the upper plate 1002 is horizontally fixed to the bottom of the cross bar 9, the lower plate 1003 is arranged parallel to the bottom of the upper plate 1002, the buffer spring 1004 is evenly installed between the bottom of the upper plate 1002 and the top of the lower plate 1003, the second sliding rod 1005 is vertically installed on the top of the lower plate 1003 and located inside the buffer spring 1004, the second sliding rod 1005 is slidably connected to the upper plate 1002, the bottom of the lower plate 1003 is evenly installed with suction cups 1006, and the output end of the negative pressure pump 1001 is connected to the suction cup 1006.

[0044] Partial working principle: When the second electric telescopic rod 6 moves downward and drives the mounting plate 7, the shaft rod 8 and the cross bar 9 to move vertically downward, the suction cup 1006 will first fit between the screen, and then the negative pressure pump 1001 will be started to extract the gas inside the suction cup 1006 to adsorb and fix the screen. When the screen is pressed down and locked, the presence of the buffer spring 1004 can protect the screen and avoid damage to the screen caused by high pressure.

[0045] In this embodiment, a vertical suction pipe 1007 is vertically installed on the top of the lower plate 1003, the bottom end of the vertical suction pipe 1007 is connected to the suction cup 1006, the vertical suction pipe 1007 passes through the interior of the upper plate 1002, and the vertical suction pipe 1007 and the upper plate 1002 are slidingly connected. An exhaust hole 1008 is provided on the outside of the vertical suction pipe 1007 and inside the upper plate 1002, and the top end of the vertical suction pipe 1007 is connected to the output end of the negative pressure pump 1001 through a hose.

[0046] Local working principle: When the screen is pressed down to seal, the buffer spring 1004 will be compressed, and the vertical suction pipe 1007 will move upward. When the exhaust hole 1008 slides out from the inside of the upper plate 1002, the suction cup 1006 will be connected to the outside world through the vertical suction pipe 1007, automatically releasing the adsorption and fixation of the screen, and then the negative pressure pump 1001 will be turned off. When the second electric telescopic rod 6 is reset, the suction cup 1006 will automatically separate from the screen.

[0047] In this embodiment, the lifting mechanism 5 includes a first rack 501, a first gear 502, a second rack 503, a support block 504 and a return spring 505. The first rack 501 is vertically fixed to the end of the mounting plate 7, the first gear 502 is rotatably mounted on the bottom end of the frame 1 and engages with the outer side of the first rack 501, and the second rack 503 is engaged with the side of the first gear 502 away from the first rack 501. The bottom end of the second rack 503 is fixedly connected to the carrier plate 4, and a support block 504 is fixed to the side of the second rack 503. A return spring 505 is provided between the top of the support block 504 and the frame 1.

[0048] Partial working principle: When the second electric telescopic rod 6 drives the mounting plate 7 to move downward, the mounting plate 7 will control the first rack 501 to move downward, and the first rack 501 will control the first gear 502 to rotate, thereby controlling the upward movement of the second rack 503 and compressing the return spring 505. The upward movement of the second rack 503 drives the screen on the carrier plate 4 to move up and fit into the suction cup 1006, and starts the negative pressure pump 1001 to complete the fixation of the screen. At this time, the tooth block on the first rack 501 and the first gear 502 are at the meshing critical point. When the second electric telescopic rod 6 controls the mounting plate 7 to move downward again, the tooth block on the first rack 501 is separated from the first gear 502, and the screen is released. Except for the engaged state, the return spring 505 quickly controls the downward movement of the second rack 503 to prevent the carrier plate 4 from hindering the downward movement of the screen. When the screen packaging is completed, the first rack 501 is reset, and the top tooth block of the first rack 501 first engages with the first gear 502. As the first rack 501 moves upward, it controls the downward movement of the second rack 503 and stretches the return spring 505. After the first rack 501 moves to the initial position, the tooth block at the bottom of the first rack 501 is no longer engaged with the first gear 502. The return spring 505 controls the second rack 503 to reset again, and the screen is transported to the top of the carrier plate 4 again for the next packaging cycle.

[0049] In this embodiment, a first sliding rod 506 is vertically fixed to the bottom end of the frame 1 . The first sliding rod 506 passes through the return spring 505 and is slidably connected to the support block 504 .

[0050] Partial working principle: The setting of the first sliding rod 506 can ensure the stability of the return spring 505.

[0051] In this embodiment, the rotating mechanism 11 includes a third rack 1101, a support rod 1102, a second gear 1103, a worm 1104, a support plate 1105, a worm wheel 1106, a sliding hole 1107, a vertical slot 1108 and a slider 1109. The third rack 1101 is vertically fixed to the bottom end of the mounting plate 7, the support rod 1102 is fixed to the inner side of the frame 1, and the end of the support rod 1102 is rotatably mounted with the second gear 1103. The second gear 1103 A worm 1104 is installed on the side, a support plate 1105 is horizontally fixed to the end of the support rod 1102, a worm gear 1106 is rotatably installed on the top of the support plate 1105, a sliding hole 1107 is opened in the middle position of the worm gear 1106, the shaft rod 8 passes through the inside of the sliding hole 1107, a vertical groove 1108 is vertically opened on the outside of the shaft rod 8, a slider 1109 is slidably installed inside the vertical groove 1108, and the slider 1109 is fixed on the inner side of the sliding hole 1107.

[0052] Partial working principle: When the tooth block at the bottom of the first rack 501 is separated from the first gear 502, and the second rack 503 moves down and resets, the tooth block at the bottom of the third rack 1101 is engaged with the second gear 1103, and the second electric telescopic rod 6 controls the mounting plate 7 to move down, the screen will move down, and at the same time the tooth block at the bottom of the third rack 1101 will be engaged with the second gear 1103 and control the rotation of the second gear 1103, the second gear 1103 drives the worm 1104 to rotate, the worm 1104 controls the worm wheel 1106 to rotate, and the worm wheel 1106 rotates. 06's rotation control shaft 8 rotates ninety degrees to move the screen to the top of the shell. At this time, the tooth block on the top of the third rack 1101 is separated from the second gear 1103. When the third rack 1101 moves down again with the mounting plate 7, the second gear 1103 will not rotate. The rotation angle of the screen is fixed, and only the downward movement is performed for packaging. After the packaging is completed, when the third rack 1101 moves up and resets, it will control the suction cup fixing mechanism 10 to rotate in the opposite direction and reset. After the suction cup fixing mechanism 10 is reset, the second gear 1103 is separated from the third rack 1101.

The first inclined guide plate 202 is symmetrically arranged at the feed end of the longitudinal conveyor belt 201, and a blocking positioning assembly for the shell is provided at the middle position of the longitudinal conveyor belt 201.

[0054] Partial working principle: During the conveying process of the shell, the position of the shell is corrected by using the first inclined guide plate 202, and then stays outside the blocking and positioning assembly to complete the screen packaging.

[0055] In this embodiment, the blocking and positioning assembly includes a first electric telescopic rod 203, a baffle 204 and a delay switch 205. The first electric telescopic rod 203 is fixed at the middle position of the side of the longitudinal conveyor belt 201. The baffle 204 is installed between the output ends of the longitudinal conveyor belt 201. A hidden groove is opened in the middle position of the longitudinal conveyor belt 201 along the width direction. A delay switch 205 electrically connected to the first electric telescopic rod 203 is provided at the middle position on both sides of the longitudinal conveyor belt 201.

[0056] Local working principle: After the shell passes between the two sets of first inclined guide plates 202, it will fit with the side of the baffle 204 to limit the position of the shell. When the screen is pressed into the interior of the shell, the buffer spring 1004 is compressed, and the upper plate 1002 will move down and contact the delay switch 205. At this time, the first electric telescopic rod 203 is started, driving the baffle 204 to move down to the inside of the hidden groove, and the longitudinal conveyor belt 201 is started to transport the encapsulated display screen to the other side of the baffle 204. When the upper plate 1002 is separated from the delay switch 205, the delay switch 205 controls the closing and resetting of the first electric telescopic rod 203 after a certain delay.
