Description

Technical Field

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

[0002] In the production and assembly of mobile phone screens, screens need to be loaded from storage trays and transported to subsequent testing, processing, or assembly steps. Currently, many production lines still use manual methods for screen loading, where operators manually remove screens from the trays and place them on a conveyor belt or at a specific workstation. This method is not only inefficient and labor-intensive, but also prone to scratches and cracks due to uneven force or impacts caused by manual handling, as mobile phone screens are delicate and easily damaged components. This results in decreased product yield and increased production costs.

[0003] While some existing automated loading equipment reduces manual operation to some extent, it often suffers from limited functionality. For example, some equipment can only handle pallets and cannot simultaneously pick up and transfer screens; others have complex structures, occupy a large area, and are poorly adaptable to pallets of different sizes. Furthermore, how to stably and accurately control the height of pallets during stacking and unloading to ensure the reliability of gripping and placement actions is also a technical challenge.

[0004] Therefore, there is an urgent need for a device with high integration, high automation, and the ability to stably and efficiently complete the functions of tray transfer and screen loading. Utility Model Content

[0005] In view of this, it is necessary to provide a mobile phone screen loading device to at least solve the problems of low efficiency, high labor intensity, low product yield and high production cost of the existing manual screen loading method in related technologies.

[0006] This application provides a mobile phone screen loading device, including a tray loading component, a tray unloading component, and a conveying component. The tray loading component and the tray unloading component are arranged side by side. The conveying component includes a fixed bracket, a linear drive module, a tray conveying module, and a screen conveying module. The fixed bracket is located on one side of the tray loading component and the tray unloading component. The linear drive module is disposed on the fixed bracket. The tray conveying module and the screen conveying module are both disposed on the linear drive module. The tray loading component is used to place a tray containing a mobile phone screen and adjust the height of the tray. The tray unloading component is used to receive the tray containing the mobile phone screen and adjust the height of the tray. The linear drive module is used to drive the tray conveying module and the screen conveying module to move horizontally. The tray conveying module is used to convey the tray on the tray loading component to the tray unloading component. The screen conveying module is used to convey the mobile phone screen in the tray on the tray unloading component to the next process step.

[0007] In one embodiment, the pallet loading assembly includes a first limiting frame and a first lifting module. The first limiting frame is located inside an external machine tool, and the first lifting module is movable up and down on the first limiting frame. Several groups of pallets can be stacked on the first lifting module. The several groups of pallets can be moved up and down on the first limiting frame through the first lifting module, thereby adjusting the relative height between the several groups of pallets and the first limiting frame.

[0008] In one embodiment, the pallet unloading assembly includes a second limiting frame and a second lifting module. The second limiting frame is located inside an external machine and on one side of the first limiting frame. The second lifting module is liftable on the second limiting frame, and several pallets can be stacked on the second lifting module.

[0009] In one embodiment, both the first limiting frame and the second limiting frame include a left side plate, a right side plate, an inner side plate, a bottom plate, and a limiting post. The left side plate, the right side plate, the inner side plate, and the bottom plate are all fixed inside an external machine tool. The limiting post is located above the bottom plate. The left side plate, the right side plate, the inner side plate, and the limiting post form a pallet lifting area. Several groups of pallets are lifted and lowered within the pallet lifting area by the first lifting module or the second lifting module.

[0010] In one embodiment, both the first and second lifting modules include a lifting drive motor, a lifting reducer, a transmission rod, a guide sleeve, a guide column, and a lifting plate. The lifting drive motor and the guide sleeve are fixed to the lower base plate. One end of the lifting reducer is mounted on the lifting drive motor and is driven by the lifting drive motor. The lower end of the transmission rod is driven by the other end of the lifting reducer, and the upper end of the transmission rod is driven by the lifting plate. The guide column is slidably disposed inside the guide sleeve and is driven by the lifting plate. Several sets of trays can be stacked on the upper end of the lifting plate. The lifting drive motor drives the lifting plate to move up and down along the direction of the guide column and the guide sleeve through the lifting reducer and the transmission rod, thereby adjusting the relative height of the several sets of trays in the tray lifting area.

[0011] In one embodiment, the linear drive module includes a linear drive motor, a linear slide, a ball screw, a screw nut, and a linear slide table. The linear slide is mounted on the fixed bracket, the linear drive motor is mounted on the linear slide, the ball screw is rotatably mounted on the linear slide and is driven by the linear drive motor, the screw nut is sleeved on the ball screw and is driven by the linear slide table, and both the tray conveying module and the screen conveying module are mounted on the linear slide table. The linear drive motor drives the ball screw to rotate on the linear slide via a coupling, thereby causing the screw nut and the linear slide table to slide on the ball screw, so that the tray conveying module and the screen conveying module can move along the fixed bracket to pick up the tray from the lifting plate of the first lifting module or the second lifting module.

[0012] In one embodiment, the tray conveying module includes a first support plate, a first pressing cylinder, a first connecting frame, and a first suction cup. 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.

[0013] 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 second support plate is disposed on the linear slide and located on one side of the first support plate.

The second connecting frame is connected to the second pressing cylinder. The air rod is fixedly connected, and the second suction cup is located on both sides of the second connecting frame. The second suction cup, the translation cylinder, and the second pressing cylinder are connected to an external air source device through air pipes. The translation cylinder drives the translation slider and the second pressing cylinder to slide along the translation 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 top of the lifting plate of the second lifting module, and conveying it to the next process through the linear slide.

[0014] The mobile phone screen feeding 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 pallet loading component, a pallet unloading component, and a conveying component into one unit. It automates the loading process of mobile phone screens. Specifically, by adopting a side-by-side design of the pallet loading and unloading components, the pallets and mobile phone screens are loaded independently. After the pallet loading component finishes feeding its own pallet, the operator can quickly replenish the pallet and mobile phone screen. Furthermore, replenishing the pallet loading component does not affect the continued feeding of the pallet unloading component to external testing, processing, or assembly devices. This eliminates downtime caused by the gradual replenishment of a single loading component, significantly improving the equipment's production efficiency and capacity. Simultaneously, its high integration results in a more compact and simplified structure, significantly reducing the footprint and lowering manufacturing and control costs. Furthermore, since the pallet transfer and mobile phone screen handling are performed by the same conveying component, 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 improves the stability and reliability of the entire system, making it highly practical. Attached Figure Description

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. 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.

[0019] Please see Figures 1 to 3 An embodiment of this application provides a mobile phone screen feeding device, including a tray feeding assembly 100, a tray unloading assembly 200, and a conveying assembly 300. The tray feeding assembly 100 and the tray unloading assembly 200 are arranged side by side. The conveying assembly 300 includes a fixed bracket 31, a linear drive module 32, a tray conveying module 33, and a screen conveying module 34. The fixed bracket 31 is located on one side of the tray feeding assembly 100 and the tray unloading assembly 200. The linear drive module 32 is mounted on the fixed bracket 31. The tray conveying module 33 and the screen conveying module 34 are both mounted on the linear drive module 32. The tray... The loading component 100 is used to place the tray 400 containing the mobile phone screen and adjust the height of the tray 400; the unloading component 200 is used to receive the tray 400 containing the mobile phone screen and adjust the height of the tray 400; the linear drive module 32 is used to drive the tray conveying module 33 and the screen conveying module 34 to move horizontally; the tray conveying module 33 is used to convey the tray 400 on the tray loading component 100 to the tray unloading component 200; the screen conveying module 34 is used to convey the mobile phone screen in the tray 400 on the tray unloading component 200 to the next process.

[0020] It should be noted that this configuration integrates the pallet loading component 100, the pallet unloading component 200, and the conveying component 300 into one unit, automating the mobile phone screen loading process. Specifically, by adopting a structural design that arranges the pallet loading component 100 and the pallet unloading component 200 side by side, the pallet 400 and the mobile phone screen are loaded independently. After the pallet 400 of the pallet loading component 100 has finished feeding, the operator can quickly replenish the pallet 400 and the mobile phone screen in the pallet loading component 100. Moreover, when the pallet loading component 100 is replenishing, it does not affect the external inspection of the pallet unloading component 200. The testing, processing, or assembly equipment continues to supply materials, eliminating downtime caused by the gradual replenishment of materials from a single feeding component. This greatly improves the equipment's production efficiency and capacity. At the same time, the high integration and compact, simplified structure of the equipment significantly reduce the footprint and lower manufacturing and control costs. Furthermore, since the pallet 400 transfer and the mobile phone screen pick-up and drop are carried out by the same conveyor component 300, 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, thereby improving the stability and reliability of the entire system.

[0021] To achieve stable feeding of the tray 400 containing the mobile phone screen, in some optional embodiments, the tray feeding assembly 100 includes a first limiting frame 11 and a first lifting module 12. The first limiting frame 11 is located inside the external machine tool, and the first lifting module 12 can be lifted and lowered on the first limiting frame 11. Several groups of trays 400 can be stacked on the first lifting module 12. The several groups of trays 400 can be lifted and lowered on the first limiting frame 11 by the first lifting module 12, thereby adjusting the relative height between the several groups of trays 400 and the first limiting frame 11.

[0022] To achieve stable feeding of mobile phone screens and stable unloading of tray 400, in some optional embodiments, the tray unloading assembly 200 includes a second limiting frame 21 and a second lifting module 22. The second limiting frame 21 is located inside the external machine and on one side of the first limiting frame 11. The second lifting module 22 can be lifted and lowered on the second limiting frame 21, and several groups of trays 400 can be stacked on the second lifting module 22. The several groups of trays 400 can be lifted and lowered on the second limiting frame 21 by the second lifting module 22, thereby adjusting the relative height between the several groups of trays 400 and the second limiting frame 21.

[0023] It should be noted that with this configuration, by setting up a pallet loading assembly 100 with a first lifting module 12 and a pallet unloading assembly 200 with a second lifting module 22, the height of the pallet stack can be automatically adjusted to ensure that the top pallet 400 is always at a preset height position that is easy to grab, thus ensuring the stability and reliability of the pallet 400 grabbing and placement actions and realizing the continuous supply and recycling of the pallet 400.

[0024] To ensure stable lifting and lowering of the first lifting module 12 within the first limiting frame 11 and the second lifting module 22 within the second limiting frame 21, in some optional embodiments, the first lifting module 12 and the second lifting module 22 are positioned within the first limiting frame 11 and the second lifting module 22, respectively. Both the first limiting frame 11 and the second limiting frame 21 include a left side plate 111, a right side plate 112, an inner side plate 113, a lower base plate 114, and a limiting post 115. The left side plate 111, right side plate 112, inner side plate 113, and lower base plate 114 are fixed within an external machine tool. The limiting post 115 is positioned above the lower base plate 114. The left side plate 111, right side plate 112, inner side plate 113, and limiting post 115 form a lifting area for the pallet 400. Several pallets 400 are lifted and lowered within this lifting area by either the first lifting module 12 or the second lifting module 22.

[0025] To achieve the purpose of adjusting the relative height of several groups of pallets 400 in the pallet 400 lifting area, in some optional embodiments, both the first lifting module 12 and the second lifting module 22 include a lifting drive motor 121, a lifting reducer 122, a transmission rod 123, a guide sleeve 124, a guide column 125, and a lifting plate 126. The lifting drive motor 121 and the guide sleeve 124 are both fixed on the lower base plate 114. One end of the lifting reducer 122 is mounted on the lifting drive motor 121 and is driven by the lifting drive motor 121. The transmission rod 123... The lower end of 3 is connected to the other end of the lifting reducer 122, the upper end of the transmission rod 123 is connected to the lifting plate 126, the guide column 125 is slidably disposed inside the guide sleeve 124 and is connected to the lifting plate 126, and several sets of pallets 400 can be stacked on the upper end of the lifting plate 126; wherein, the lifting drive motor 121 drives the lifting plate 126 to rise and fall along the direction of the guide column 125 and the guide sleeve 124 through the lifting reducer 122 and the transmission rod 123, thereby adjusting the relative height of several sets of pallets 400 in the lifting area of ​​the pallet 400.

[0026] To further achieve stable material feeding between the pallet loading assembly 100, the pallet unloading assembly 200, and external devices, in some optional embodiments, the linear drive module 32 includes a linear drive motor 321, a linear slide 322, a ball screw, a screw nut, and a linear slide table 323. The linear slide 322 is mounted on a fixed bracket 31, the linear drive motor 321 is mounted on the linear slide 322, the ball screw is rotatably mounted on the linear slide 322 and is connected to the linear drive motor 321, and the screw nut is sleeved on the linear slide table 323. The ball screw is connected to the linear slide 323 for transmission. Both the tray conveying module 33 and the screen conveying module 34 are mounted on the linear slide 323. The linear drive motor 321 drives the ball screw to rotate on the linear slide 322 through a coupling, thereby causing the screw nut and the linear slide 323 to slide on the ball screw. This allows the tray conveying module 33 and the screen conveying module 34 to move on the fixed bracket 31 to pick up the tray 400 on the lifting plate 126 of the first lifting module 12 or the second lifting module 22.

[0027] It should be noted that this setup, using a linear transmission module 32 (such as a ball screw and screw nut structure) for drive, ensures high transmission accuracy and smooth operation. The pallet conveying module 33 and the screen conveying module 34 are independently set up but can work together, respectively responsible for the circulation of the pallet 400 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.

[0028] To further achieve stable material feeding between the pallet loading assembly 100 and the pallet unloading assembly 200, in some optional embodiments, the pallet conveying module 33 includes a first support plate 331, a first pressing cylinder 332, a first connecting frame 333, and a first suction cup 334. The first support plate 331 is located on one side of the linear slide 323. The first pressing cylinder 332 is fixed on the first support plate 331. The first connecting frame 333 is fixedly connected to the air rod of the first pressing cylinder 332. The first suction cup 334 is located around the first connecting frame 333. The first suction cup 334 and the first pressing cylinder 332 are connected to an external air source device through an air pipe. The first pressing cylinder 332 drives the first connecting frame 333 and the first suction cup 334 to press down through the air rod, thereby adsorbing the pallet 400 at the uppermost end of the lifting plate 126 of the first lifting module 12 and placing it on the lifting plate 126 of the second lifting module 22 through the linear slide 323.

[0029] To further achieve stable material feeding between the pallet unloading assembly 200 and the external device, in some optional embodiments, the screen conveying module 34 includes a second support plate 341, a translation cylinder 342, a translation slide rail 343, a translation slider 344, a second pressing cylinder 345, a second connecting frame 346, and a second suction cup 347. The second support plate 341 is mounted on the linear slide 323 and located on one side of the first support plate 331. The translation cylinder 342 and the translation slide rail 343 are both fixed to the first support plate 331. The translation slider 344 is sleeved on the translation slide rail 343 and is connected to the pneumatic rod of the translation cylinder 342. The second pressing cylinder 345 is fixed to the translation slide rail 343. On block 344, the second connecting frame 346 is fixedly connected to the air rod of the second pressing cylinder 345. The second suction cup 347 is located on both sides of the second connecting frame 346. The second suction cup 347, the translation cylinder 342, and the second pressing cylinder 345 are connected to an external air source device through air pipes. The translation cylinder 342 drives the translation slider 344 and the second pressing cylinder 345 to slide along the translation rail 343 through the air rod. The second pressing cylinder 345 drives the second connecting frame 346 and the second suction cup 347 to press down through the air rod, thereby adsorbing the mobile phone screen in the tray 400 at the top of the lifting plate 126 of the second lifting module 22, and then conveying it to the next process through the linear slide table 323.

[0030] It should be noted that this setup, using a suction cup gripping method (the first suction cup 334 grips the tray 400, and the second suction cup 347 grips the screen), avoids mechanical clamping damage to the tray 400 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.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
