Description

Material changing device and material changing production line for commercial display diaphragm

[Technical field]

The embodiments of the present application relate to the technical field of display device assembly, and in particular to a material replacement device and a material replacement production line for commercial display film.

[Background technology]

Display screens are an essential part of electronic products such as smartphones and tablets. They can not only display information such as video patterns intuitively, but users can also input various commands through the screen to complete different functions. Display screens usually use glass as the substrate, and various films are attached to the glass to protect the glass and produce different optical effects. Therefore, the film-attaching process is an essential processing step in the production and manufacturing of display screens.

The film laminating process is usually carried out on a film laminating table, which is difficult to adapt to films of different sizes. Therefore, different sizes of film laminating tables are required for films of different sizes. In addition, the transportation of films is usually done manually. The transportation of large-sized films is not only time-consuming and labor-intensive, but also has the risk of film bending and damage during the transportation process.

Display screens are an essential part of electronic products such as smartphones and tablets. They can not only display information such as video patterns intuitively, but users can also input various commands through the screen to complete different functions. Display screens usually use glass as the substrate, and various films are attached to the glass to protect the glass and produce different optical effects. Therefore, the film-attaching process is an essential processing step in the production and manufacturing of display screens.

The inventor of the present application found in the process of implementing the present utility model that the transportation of diaphragms usually requires more than three operators to lift the diaphragm materials and place them on the loading platform, which is not only time-consuming and labor-intensive, but also prone to bending, deformation, and even damage of the diaphragms when they are transported. When using a transfer device to transport diaphragms, the transfer device is also difficult to adapt to diaphragms of different sizes and types. Therefore, there are many types of transfer equipment and their versatility is poor. When the diaphragms on the transfer equipment are transferred to the film sticking table, the diaphragms are also prone to bending and deformation. For large-sized diaphragms, not only is the labor cost high, but there is also a risk of diaphragm damage.

To improve the above problems, in the first aspect, an embodiment of the present application proposes a material changing device 100 for commercial display film. Please refer to FIG. 1 . The material changing device 100 includes a material changing vehicle 10, a support plate 20, a first guide rail 30, and a plurality of positioning posts 40. The material changing vehicle 10 can move along the first guide rail 30 so that the material changing vehicle 10 moves to a predetermined position. The support plate 20 can carry a commercial display film 50 for the film pasting process. The plurality of positioning posts 40 can enclose a positioning space on the support plate 20 to position and clamp the commercial display film 50 on the support plate 20.

The above-mentioned material change vehicle 10 is used to transport the commercial display film 50 to save manpower and improve the transportation efficiency. Referring to FIG. 2 , the material change vehicle 10 includes a bracket 11, and a moving wheel 12 is connected to the bottom of the bracket 11. For example, the bracket 11 is a rectangular frame structure as a whole, and a moving wheel 12 is connected to each of the four corners of the bottom to improve the stability of the movement of the material change vehicle 10. Among them, the moving wheel 12 can be a universal wheel to facilitate the movement and reversing of the material change vehicle 10.

Please further refer to Figure 3. The material changing cart 10 is also connected to a first guide wheel 13. The first guide wheel 13 can be set at the bottom of the bracket 11 and located between the two moving wheels 12. The first guide wheel 13 can guide the material changing cart 10 to move in a specific direction, for example, guide the material changing cart 10 to transport the display film 50 along a specific track.

For the above-mentioned support plate 20, please refer to Figures 1, 2 and 4. The support plate 20 is arranged on the above-mentioned material changing vehicle 10. For example, the support plate 20 is arranged at the upper end of the bracket 11, and the above-mentioned moving wheel 12 and the first guide wheel 13 are both arranged at the bottom of the bracket 11. The support plate 20 is used to support the commercial display film 50. For example, the support plate 20 has a support surface 21, and the support surface 21 is arranged away from the above-mentioned moving wheel 12. The support surface 21 is provided with a plurality of positioning holes 22. Among them, the plurality of positioning holes 22 enclose a plurality of positioning areas on the support surface 21 (various types of positioning areas enclosed by dotted lines in Figure 4 can be adopted), and the positioning areas at least include a first positioning area and a second positioning area, and the first positioning area is located in the second positioning area.

For example, at least two positioning holes 22 are arranged on the support surface 21 along the first direction X, and/or at least two positioning holes 22 are arranged on the support surface 21 along the second direction Y. Each positioning hole 22 can be used to insert the positioning column 40, wherein the first direction X is perpendicular to the second direction Y.

For the first guide rail 30, please refer to FIG. 1 and FIG. 5. The first guide rail 30 is arranged at the bottom of the bracket 11. The first guide wheel 13 is arranged on the first guide rail 30 and can move along the first guide rail 30, so that the material-changing vehicle 10 moves along the first guide rail 30, ensuring that the material-changing vehicle 10 can move to a predetermined position. For example, the first guide rail 30 is arranged along the first direction X, and the first guide wheel 13 moves along the first guide rail 30, so that the material-changing vehicle 10 can move along the first direction X. In some other embodiments, the first guide rail 30 is arranged to be curved, and the first guide wheel 13 is a universal wheel, so that the first guide wheel 13 can also move along the curved first guide rail 30.

In some embodiments, the first slide rail has a slide groove 31, and the first guide wheel 13 is movably disposed in the slide groove 31. For example, referring to FIG3 and FIG5, the bracket 11 is connected to two first guide wheels 13, the rotation axes of the two first guide wheels 13 are parallel to the third direction Z, and the two first guide wheels 13 can roll on the two inner side walls of the slide groove 31 respectively; for another example, the rotation axis of the first guide wheel 13 is parallel to the second direction Y, and the first guide wheel 13 can roll directly on the inner bottom wall of the slide groove 31. Among them, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

Along the length direction (first direction X) of the first guide rail 30, the first guide rail 30 includes a first end 32 and a second end 33 that are arranged opposite to each other, and the second end 33 is further provided with a guide groove 34, and the guide groove 34 is connected to the slide groove 31. The first guide wheel 13 can slide from the guide groove 34 into the slide groove 31, and can move to the first end 32 in the slide groove 31.

Among them, along the direction from the guide groove 34 to the slide groove 31 (the opposite direction of the first direction X), the cross-sectional area of the guide groove 34 in the second direction Y gradually decreases and finally coincides with the cross-sectional area of the slide groove 31. That is, along the direction from the slide groove 31 to the guide groove 34, the cross-sectional area of the guide groove 34 in the second direction Y gradually increases. The opening of the guide groove 34 at one end away from the slide groove 31 is larger, which makes it easier for the first guide wheel 13 of the material changing vehicle 10 to enter the guide groove 34, so as to limit the first guide wheel 13, and gradually move to the slide groove 31 under the guidance of the guide groove 34, thereby limiting the movement of the material changing vehicle 10 along the first guide rail 30.

Please refer to FIG. 1 , FIG. 5 and FIG. 6 . In some embodiments, the material changing device 100 further includes a positioning and clamping mechanism 60 . When the material changing vehicle 10 moves to a predetermined position along the first guide rail 30 , the positioning and clamping mechanism 60 can position and clamp the material changing vehicle 10 .

The positioning and clamping mechanism 60 includes a positioning plate 61 and a hooking member 62. Along the first direction X, the positioning plate 61 is arranged at one end of the first guide rail 30, for example, at the first end portion 32 of the first guide rail 30, and the material changing vehicle 10 can move along the first guide rail 30 to the first end portion 32 and abut against the positioning plate 61. Among them, a buffer pad 63 can be provided on the end surface of the positioning plate 61 facing the material changing vehicle 10, for example, a flexible pad such as rubber, silicone or foam can be provided to reduce the impact of the material changing vehicle 10 on the positioning plate 61. The hooking member 62 is connected to the positioning plate 61. When the material changing vehicle 10 abuts against the positioning plate 61 at the first end portion 32, the hooking member 62 can be hooked with the material changing vehicle 10, for example, hooked with the bracket 11 of the material changing vehicle 10, so that the material changing vehicle 10 is fixed to the positioning plate 61, thereby reducing the shaking of the material changing vehicle 10, so as to facilitate the film pasting process.

Please further refer to FIG. 7 , the positioning and clamping mechanism 60 further includes a rotating shaft 64 , a rotating member 65 and a driving member 66 .

The rotating shaft 64 is arranged on the positioning plate 61. For example, the positioning plate 61 includes a first positioning plate 61a and a second positioning plate 61b that are arranged opposite to each other. The first positioning plate 61a and the second positioning plate 61b are arranged opposite to each other in the second direction Y. The rotating shaft 64 is connected between the first positioning plate 61a and the second positioning plate 61b, and the rotating shaft 64 is arranged along the second direction Y.

The rotating member 65 includes a second portion 65b, and the hook member 62 includes a first portion 62a connected to the second portion 65b, the first portion 62a has a first surface 62a1 and a second surface 62a2 that are oppositely arranged (for example, the first surface 62a1 and the second surface 62a2 are oppositely arranged along the third direction Z in FIG. 7 ), the second portion 65b is bent in a direction perpendicular to the first surface 62a1, and the second portion 65b protrudes from the second surface 62a2, and the rotating shaft 64 is arranged between the first portion 62a and the second portion 65b, and the first portion 62a and the second portion 65b can rotate around the rotating shaft 64. The hook member 62 also includes a hook portion 62b, the hook portion 62b is connected to the first portion 62a, and the hook portion 62b is bent in a direction perpendicular to the first surface 62a1, and the hook portion 62b protrudes from the first surface 62a1. The rotating shaft 64 is arranged between the first part 62a and the second part 65b, so that the first part 62a, the rotating shaft 64 and the second part 65b form a lever-like structure. When the first part 62a is lifted, the second part 65b is lowered, and when the second part 65b is lifted, the first part 62a is lowered. The above-mentioned hook member 62 is connected to the first part 62a.

The driving member 66 is connected to the second part 65b, and is used to drive the rotating member 65 to rotate around the rotating shaft 64. For example, the driving member 66 drives the second part 65b to descend, and the second part 65b is lifted, so that the hooking portion 62b is hooked with the material-changing vehicle 10; or the driving member 66 drives the second part 65b to lift, and the first part 62a is lowered, so that the hooking portion 62b is detached from the material-changing vehicle 10.

Optionally, the driving member 66 includes a cylinder, and the telescopic end 661 of the cylinder is hinged to the second part 65b, and the hinge axis is parallel to the rotating shaft 64. The cylinder is pushed out, so that the second part 65b descends, and the first part 62a is lifted, and the hooking part 62b on the first part 62a is directly hooked and fixed to the material changing vehicle 10. The cylinder retracts, so that the second part 65b is lifted, and the first part 62a descends, and the hooking member 62 on the first part 62a is disengaged from the material changing vehicle 10 to release the lock on the material changing vehicle 10. In some other embodiments, the rotating member 65 can also be directly fixed to the rotating shaft 64. In this case, the driving member 66 can also use a motor. The driving member 66 directly drives the rotating shaft 64 to rotate, so as to drive the rotating member 65 to rotate, thereby realizing the hooking of the hooking member 62 to the material changing vehicle 10 or disengaging from the material changing vehicle 10.

In some embodiments, the positioning clamping mechanism 60 further includes a mounting seat, and the cylinder is rotatably disposed on the mounting seat, and the rotation axis is parallel to the rotating shaft 64. For example, referring to FIG. 6 , when the cylinder is contracted, the cylinder rotates so that the telescopic end 661 is lifted upward, and when the cylinder is extended, the telescopic end 661 can be lowered to reduce the interference between the telescopic end 661 of the cylinder and the second part 65b. It should be noted that in the embodiments of the present application, the error range can be regarded as parallel, for example, within the error range of 0 to 5°.

In some embodiments, please further refer to FIG. 2 , a hook frame 14 is provided at one end of the material changing vehicle 10 facing the positioning plate 61, for example, the hook frame 14 is connected to the bracket 11. Under the drive of the driving member 66, the hook member 62 is hooked to the hook frame 14 or is disengaged from the hook frame 14. For example, the hook frame 14 encloses a hook space 141, and when the driving member 66 drives the second part 65b to descend, the first part 62a is lifted so that the hook member 62 extends into the hook space 141 and is hooked to the hook frame 14.

Referring to FIG. 1 , FIG. 8 and FIG. 9 , the first guide plate 70 and the second guide plate 80 are arranged relatively to each other along the second direction Y, and a guide space 90 is formed between the first guide plate 70 and the second guide plate 80. The above-mentioned material changing vehicle 10 can move along the guide space 90, and the second end portion 33 of the first guide rail 30 is arranged in the guide space 90. Through the guidance of the guide space 90, the first guide wheel 13 of the material changing vehicle 10 can quickly enter the guide groove 34 and then enter the slide groove 31. By setting the guiding positioning of the first guide plate 70 and the second guide plate 80, the material changing vehicle 10 can quickly enter the predetermined track. Among them, the opening of the guide space 90 away from the positioning plate 61 can also be set larger to facilitate the material changing vehicle 10 to quickly enter the guide space 90.

In the second aspect, the embodiments of the present application further propose a material replacement production line 1000 for commercial display membranes. Please refer to Figure 10. The material replacement production line 1000 includes a material replacement device 100 as described in any embodiment of the first aspect above, as well as a material receiving device 200, a frame 300 and a transfer mechanism 400.

For the above-mentioned receiving device 200, the receiving device 200 includes a receiving platform 210 for receiving the commercial display film 50. For example, the receiving device 200 includes a support frame 220, and the receiving platform 210 can be arranged on the support frame 220. Similar to the material changing device 100, a plurality of positioning holes 22 and positioning columns 40 can also be arranged on the receiving platform 210 of the receiving device 200 to accommodate the receiving of commercial display films 50 of similar sizes.

For the above-mentioned frame 300, the frame 300 may adopt a gantry structure. For example, the frame 300 includes a first column 310, a second column 320, and a crossbeam 330 connected between the first column 310 and the second column 320. Optionally, a third column 340 may be arranged between the first column 310 and the second column 320, and the third column 340 is connected to and supports the crossbeam 330 to improve the overall stability of the frame 300. The crossbeam 330 is located above the material changing device 100 and the material receiving device 200, and a second guide rail 331 is also arranged on the crossbeam 330. For example, the second guide rail 331 is arranged along the second direction Y, and the material changing device 100 and the material receiving device 200 are arranged in sequence along the second direction Y.

The above-mentioned transfer mechanism 400 can be movably arranged on the second guide rail 331. For example, the second guide rail 331 adopts a linear rail or a hard rail, and the transfer mechanism 400 can be driven by a screw nut so that the transfer mechanism 400 can move along the second guide rail 331. The transfer mechanism 400 includes a transfer member 410 for grabbing the commercial display film 50. The transfer member 410 can adopt a grabbing member such as a manipulator or a suction cup. The transfer member 410 is used to carry the commercial display film 50 between the material changing device 100 and the material receiving device 200. For example, the transfer mechanism 400 moves along the second guide rail 331 to the top of the material changing device 100, the transfer member 410 absorbs the commercial display film 50 on the material changing device 100, and the transfer mechanism 400 moves along the second guide rail 331 to the top of the material receiving device 200, and places the commercial display film 50 on the material receiving table 210 of the material receiving device 200 to complete the automatic transfer of the commercial display film 50, which not only reduces labor costs, but also reduces bending and deformation of the commercial display film 50 caused by transportation.
