Description

Technical Field

[0001] This utility model relates to the field of mobile phone screen processing technology, and in particular to a mobile phone screen loading and flipping device. Background Technology

[0002] In the automated production, testing, and bonding processes of mobile phone screens, it is often necessary to operate on both the front and back sides, which necessitates efficient and reliable loading and flipping equipment. Existing equipment of this type typically suffers from two main drawbacks: First, a bottleneck in production efficiency: most equipment uses a single loading bin. Once the screens in the bin are processed, the entire production line must be stopped, waiting for manual reloading before it can restart. This frequent start-stop cycle not only reduces equipment utilization but also becomes a key factor restricting the overall production capacity. Second, redundancy in equipment structure. To complete the entire process from loading and sorting to flipping, a common solution is to use multiple independent, single-function modules (such as dedicated pallet handling mechanisms, dedicated screen gripping robots, and dedicated flipping tables) connected in series on an assembly line. This approach results in a complex overall equipment structure, a large footprint, high costs, and significant difficulties in coordinating and controlling the modules, affecting operational stability and reliability.

[0003] Therefore, there is an urgent need in this field for a compact device that can integrate feeding, conveying and flipping functions and achieve uninterrupted continuous production, in order to overcome the shortcomings of existing technologies in terms of production efficiency and equipment integration.

The machine base is used to house the first loading mechanism, the second loading mechanism, the conveying mechanism, and the flipping mechanism. The first loading mechanism is used to place a tray containing a mobile phone screen and adjust the height of the tray. The second loading mechanism is used to receive the tray containing the mobile phone screen and adjust the height of the tray. The conveying mechanism is used to convey the tray from the first loading mechanism to the second loading mechanism or to convey the mobile phone screen from the tray on the second loading mechanism to the flipping mechanism.

The first support plate is disposed on one side of the linear slide, the first pressing cylinder is fixed to the first support plate, the first connecting frame is fixedly connected to the air rod of the first pressing cylinder, and the first suction cup is disposed around the first connecting frame. The first suction cup and the first pressing cylinder are connected to an external air source device through an air pipe. The first pressing cylinder drives the first connecting frame and the first suction cup to press down through the air rod, thereby adsorbing the tray at the uppermost end of the lifting plate of the first lifting module and placing it on the lifting plate of the second lifting module through the linear slide.

[0012] In one embodiment, the screen conveying module includes a second support plate, a translation cylinder, a translation slide rail, a translation slider, a second pressing cylinder, a second connecting frame, and a second suction cup.

The translation cylinder drives the translation slider and the second pressing cylinder to slide along the translation slide rail through the air rod. The second pressing cylinder drives the second connecting frame and the second suction cup to press down through the air rod, thereby adsorbing the mobile phone screen in the tray at the uppermost end of the lifting plate of the second lifting module and placing it on the flipping mechanism through the linear slide platform.

The flipping base is disposed on both sides of the flipping main shaft. The third suction cup is disposed on the flipping base and is connected to an external air source device through an air pipe. The third suction cup is used to adsorb the mobile phone screen transferred by the second suction cup and drive the mobile phone screen.

[0015] The mobile phone screen flipping device provided by this utility model has the following significant advantages compared with the prior art: This utility model features a reasonable design and novel structure, integrating a first feeding mechanism, a second feeding mechanism, a conveying mechanism, and a flipping mechanism into one unit. It automates the feeding and flipping processes of mobile phone screens. Specifically, by employing a structure design with the first and second feeding mechanisms arranged side-by-side, the tray and mobile phone screens are fed independently. Once the tray of the first feeding mechanism has finished feeding, the operator can quickly replenish the tray and mobile phone screens. Furthermore, replenishment by the first feeding mechanism does not affect the continued feeding of the flipping mechanism by the second feeding mechanism, eliminating downtime caused by replenishment by a single feeding mechanism and significantly improving efficiency. This design improves the equipment's production efficiency and capacity. It replaces the traditional approach of requiring two independent actuators by using two feeding mechanisms to move the entire pallet between two feeding mechanisms and to pick up and place individual phone screens from the pallet onto the flipping mechanism. This results in a more compact and simplified equipment structure, significantly reducing the footprint and manufacturing and control costs. Furthermore, since the pallet transfer and phone screen picking / pickup are handled by the same conveyor mechanism, the two actions are naturally coordinated in terms of spatial path and temporal sequence, reducing the complex communication and calibration requirements between multiple independent modules. This enhances the stability and reliability of the entire system, making it highly practical. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Please see Figures 1 to 6An embodiment of this application discloses a mobile phone screen feeding and flipping device, comprising a machine base 100, a first feeding mechanism 200, a second feeding mechanism 300, a conveying mechanism 400, and a flipping mechanism 500. The first feeding mechanism 200, the second feeding mechanism 300, the conveying mechanism 400, and the flipping mechanism 500 are all housed within the machine base 100. The first feeding mechanism 200 and the second feeding mechanism 300 are arranged side-by-side, the conveying mechanism 400 is located on one side of the first feeding mechanism 200 and the second feeding mechanism 300, and the flipping mechanism 500 is located at the discharge end of the conveying mechanism 400. The machine base 100 is used to house the first feeding mechanism 200 and the second feeding mechanism 300. 0. Conveying mechanism 400 and flipping mechanism 500; First feeding mechanism 200, used to place tray 600 containing mobile phone screens and adjust the height of tray 600; Second feeding mechanism 300, used to receive tray 600 containing mobile phone screens and adjust the height of tray 600; Conveying mechanism 400, used to convey tray 600 on first feeding mechanism 200 to second feeding mechanism 300 or to convey mobile phone screens in tray 600 on second feeding mechanism 300 to flipping mechanism 500; Flipping mechanism 500, used to receive mobile phone screens conveyed by conveying mechanism 400 and flip the mobile phone screens.

[0021] It should be noted that this configuration integrates the first feeding mechanism 200, the second feeding mechanism 300, the conveying mechanism 400, and the flipping mechanism 500 into one unit, automating the feeding and flipping process of mobile phone screens. Specifically, by adopting a structural design with the first feeding mechanism 200 and the second feeding mechanism 300 arranged side by side, the tray 600 and the mobile phone screen are fed independently. After the tray 600 of the first feeding mechanism 200 has finished feeding, the operator can quickly replenish the tray 600 and the mobile phone screen. Moreover, when the first feeding mechanism 200 is replenishing, it does not affect the second feeding mechanism 300's continued feeding of the flipping mechanism 500, eliminating the problems caused by replenishing from a single feeding mechanism. The reduced downtime significantly improves the equipment's production efficiency and capacity. Furthermore, the design, which involves moving the entire pallet 600 between two feeding mechanisms and simultaneously transferring individual phone screens from the pallet 600 to the flipping mechanism 500, replaces the traditional approach requiring two independent actuators. This results in a more compact and simplified equipment structure, significantly reducing the footprint and lowering manufacturing and control costs. Simultaneously, since the pallet 600 transfer and phone screen handling are handled by the same conveyor mechanism 400, the two actions are naturally coordinated in terms of spatial path and temporal sequence, reducing the complex communication and calibration requirements between multiple independent modules and thus improving the overall system's stability and reliability.

[0022] To achieve stable feeding of the tray 600 containing the mobile phone screen, in some optional embodiments, the first feeding mechanism 200 includes a first limiting frame 21 and a first lifting module 22. The first limiting frame 21 is disposed within the machine base 100, and the first lifting module 22 can be lifted and lowered on the first limiting frame 21. Several groups of trays 600 can be stacked on the first lifting module 22. The several groups of trays 600 can be lifted and lowered on the first limiting frame 21 by the first lifting module 22, thereby adjusting the relative height between the several groups of trays 600 and the first limiting frame 21.

[0023] To achieve stable feeding of mobile phone screens, in some optional embodiments, the second feeding mechanism 300 includes a second limiting frame 31 and a second lifting module 32. The second limiting frame 31 is located inside the machine base 100 and on one side of the first limiting frame 21. The second lifting module 32 can be lifted and lowered on the second limiting frame 31, and several sets of trays 600 can be stacked on the second lifting module 32. The several sets of trays 600 can be lifted and lowered on the second limiting frame 31 by the second lifting module 32, thereby adjusting the relative height between the several sets of trays 600 and the second limiting frame 31.

[0024] It should be noted that with this configuration, by setting up a first feeding mechanism 200 with a first lifting module 22 and a second feeding mechanism 300 with a second lifting module 32, the height of the pallet stack can be automatically adjusted to ensure that the top pallet 600 is always at a preset height position that is easy to grab, thus ensuring the stability and reliability of the pallet 600 grabbing and placement actions, and realizing the continuous supply and recycling of the pallet 600.

[0025] To further achieve stable feeding of the tray 600 and the mobile phone screen, in some optional embodiments, both the first lifting module 22 and the second lifting module 32 include a lifting drive motor 221, a lifting reducer 222, a transmission rod 223, a guide sleeve 224, a guide column 225, and a lifting plate 226. The lifting drive motor 221 and the guide sleeve 224 are both fixed to the first limiting frame 21 or the second limiting frame 31. One end of the lifting reducer 222 is mounted on the lifting drive motor 221 and is connected to the lifting drive motor 221 for transmission. The lower end of the transmission rod 223... One end is connected to the other end of the lifting reducer 222, the upper end of the transmission rod 223 is connected to the lifting plate 226, the guide column 225 is slidably disposed inside the guide sleeve 224 and is connected to the lifting plate 226, and several sets of pallets 600 can be stacked on the upper end of the lifting plate 226; wherein, the lifting drive motor 221 drives the lifting plate 226 to rise and fall along the direction of the guide column 225 and the guide sleeve 224 through the lifting reducer 222 and the transmission rod 223, thereby adjusting the relative height of several sets of pallets 600 in the first limiting frame 21 or the second limiting frame 31.

[0026] To achieve stable feeding by the first feeding mechanism 200, the second feeding mechanism 300, and the flipping mechanism 500, in some optional embodiments, the conveying mechanism 400 includes a fixed support 41, a linear drive module 42, a pallet conveying module 43, and a screen conveying module 44. The fixed support 41 is located inside the machine base 100 and on one side of the first limiting frame 21 and the second limiting frame 31. The linear drive module 42 is mounted on the fixed support 41, and both the pallet conveying module 43 and the screen conveying module 44 are mounted on the linear drive module 42. The pallet conveying module 43 and the screen conveying module 44 are translated on the fixed support 41 via the linear drive module 42.

[0027] To achieve stable transmission between the pallet conveying module 43 and the screen conveying module 44, in some optional embodiments, the linear transmission module 42 includes a linear drive motor 421, a linear slide 422, a ball screw, a screw nut, and a linear slide table 423. The linear slide 422 is mounted on a fixed bracket 41, the linear drive motor 421 is mounted on the linear slide 422, the ball screw is rotatably mounted on the linear slide 422 and is connected to the linear drive motor 421, the screw nut is sleeved on the ball screw and is connected to the linear slide table 423, and both the pallet conveying module 43 and the screen conveying module 44 are mounted on the linear slide table 423. The linear drive motor 421 drives the ball screw to rotate on the linear slide 422 through a coupling, thereby causing the screw nut and the linear slide table 423 to slide on the ball screw, so that the pallet conveying module 43 and the screen conveying module 44 can translate on the fixed bracket 41.

[0028] It should be noted that this setup, using a linear drive module 42 (such as a ball screw structure) for driving, ensures high transmission accuracy and smooth operation. The pallet conveying module 43 and the screen conveying module 44 are independently set up but can work together, respectively responsible for the circulation of the pallet 500 and the picking and loading of the screen. The division of labor is clear, the actions are precise, mutual interference is avoided, and the loading cycle time is improved.

[0029] To achieve stable feeding between the first feeding mechanism 200 and the second feeding mechanism 300, in some optional embodiments, the pallet conveying module 43 includes a first support plate 431, a first pressing cylinder 432, a first connecting frame 433, and a first suction cup 434.

The first connecting frame 433 is fixedly connected to the air rod of the first pressing cylinder 432. The first suction cup 434 is located around the first connecting frame 433. The first suction cup 434 and the first pressing cylinder 432 are connected to an external air source device through an air pipe. The first pressing cylinder 432 drives the first connecting frame 433 and the first suction cup 434 to press down through the air rod, thereby adsorbing the pallet 600 at the uppermost end of the lifting plate 226 of the first lifting module 22 and placing it on the lifting plate 226 of the second lifting module 32 through the linear slide table 423.

[0030] To achieve stable feeding between the second feeding mechanism 300 and the flipping mechanism 500, in some optional embodiments, the screen conveying module 44 includes a second support plate 441, a translation cylinder 442, a translation slide rail 443, a translation slider 444, a second pressing cylinder 445, a second connecting frame 446, and a second suction cup 447. The second support plate 441 is mounted on the linear slide table 423 and located on one side of the first support plate 431. The translation cylinder 442 and the translation slide rail 443 are both fixed to the first support plate 431. The translation slider 444 is sleeved on the translation slide rail 443 and is connected to the pneumatic rod of the translation cylinder 442. The second pressing cylinder 445 is fixed to the translation slider. On 444, the second connecting frame 446 is fixedly connected to the air rod of the second pressing cylinder 445. The second suction cup 447 is located on both sides of the second connecting frame 446. The second suction cup 447, the translation cylinder 442, and the second pressing cylinder 445 are connected to an external air source device through air pipes. The translation cylinder 442 drives the translation slider 444 and the second pressing cylinder 445 to slide along the translation slide rail 443 through the air rod. The second pressing cylinder 445 drives the second connecting frame 446 and the second suction cup 447 to press down through the air rod, thereby adsorbing the mobile phone screen in the tray 600 at the top of the lifting plate 226 of the second lifting module 32, and placing it on the flipping mechanism 500 through the linear slide table 423.

[0031] It should be noted that this setup, using a suction cup gripping method (the first suction cup 434 grips the tray 600, and the second suction cup 447 grips the screen), avoids mechanical clamping damage to the tray 600 and the fragile mobile phone screen, effectively reducing the risk of scratches and breakage of the screen during transportation and helping to improve product yield.

[0032] To achieve stable screen rotation, in some optional embodiments, the rotation mechanism 500 includes a rotation translation module 51, a rotation lifting module 52, and a screen rotation module 53. The rotation translation module 51 is fixed on the machine base 100 and located on one side of the fixed bracket 41. The rotation lifting module 52 is disposed on the rotation translation module 51, and the screen rotation module 53 is disposed on the rotation lifting module 52. The rotation translation module 51 is used to move the rotation lifting module 52 and the screen rotation module 53 closer to or further away from the fixed bracket 41. The rotation lifting module 52 is used to move the screen rotation module 53 up and down. The screen rotation module 53 is used to receive and absorb the mobile phone screen transferred by the second suction cup 447 and rotate the mobile phone screen.

The rotation drive wheel 533 and the rotation driven wheel 534 are rotatably mounted on the docking platform 531. The rotation timing belt 535 covers the rotation drive wheel 533 and the rotation driven wheel 534. The outer surface of 4 has a rotating spindle 536 located in the middle of the rotating driven wheel 534 and rotating synchronously with the rotating driven wheel 534. A rotating seat 537 is located on both sides of the rotating spindle 536. A third suction cup 538 is located on the rotating seat 537 and is connected to an external air source device through an air pipe. The third suction cup 538 is used to adsorb the mobile phone screen transferred by the second suction cup 447 and drive the mobile phone screen. The rotating drive motor 532 drives the rotating drive wheel 533 to rotate through the rotating shaft, thereby driving the rotating driven wheel 534, the rotating synchronous belt 535, the rotating spindle 536 and the rotating seat 537 to rotate synchronously, so that the mobile phone screen adsorbed on the third suction cup 538 is rotated.
