Description

Technical Field

[0001] This application relates to the field of mobile phone screen coating technology, and in particular to a suspended structure CG coating platform. Background Technology

[0002] Currently, mobile phone screens consist of two parts: an inner screen and an outer screen. The inner screen is primarily responsible for display, typically using an LCD or OLED panel. The outer screen, on the other hand, mainly protects the screen with glass and a printed touch layer. Generally, the outer screen of a mobile phone is the cover glass, or the protective glass of the phone's casing, often abbreviated as CG.

[0003] Regarding the aforementioned technologies, the inventors believe that in the CG surface protective film application process, the common application method is roller application. Because the coating platform itself is made of aluminum alloy, which has exceptionally high hardness, while the CG ink coating is very fragile, during the manufacturing process, the ink coating on the CG surface directly contacts and scratches the platform, making it extremely easy for scratches to occur, resulting in batch defects and preventing CCD cameras from capturing clear images. This has become a major pain point in the manufacturing industry. Summary of the Invention

[0004] In order to improve the problems of easy scratching of ink coating and unclear CCD camera images during the application of CG surface protective film, the purpose of this application is to provide a suspended structure CG coating platform.

[0005] The suspended CG coating platform provided in this application adopts the following technical solution:

[0006] A suspended CG coating platform includes a platform and a coating plate. The coating plate is installed on the platform, and a suspended groove is formed on the coating plate at the position corresponding to the CG ink coating. The junction between the edge of the suspended groove and the surface of the coating plate is smooth. Reflective paper is covered at the junction between the edge of the suspended groove and the surface of the coating plate. A debris removal device is also installed on the platform to remove glass shards and dust particles remaining on the surface of the reflective paper.

[0007] By adopting the above technical solution, after the CG is bonded to the laminating plate, the position of the CG ink coating is directly opposite the groove, so that the CG ink coating is not likely to come into direct contact with the surface of the laminating platform, reducing the occurrence of damage to the CG ink coating. After the reflective paper is covered at the junction of the groove edge and the surface of the laminating plate, the reflective paper has the function of softening and improving the clarity of CCD camera shooting. Moreover, after each shooting, the glass shards and dust particles remaining on the surface of the reflective paper are removed by the impurity removal device, which improves the service life of the reflective paper.

[0008] Optionally, the suspended groove has a depth of 2mm and a width of 5mm.

[0009] By adopting the above technical solution, the depth and width of the suspended groove are set according to the specifications and dimensions of the conventional CG model, thereby improving the fit for use.

[0010] Optionally, a shallow receiving groove is provided at the junction of the edge of the suspended groove and the surface of the film plate, and the shallow receiving groove is used to place reflective paper.

[0011] By adopting the above technical solution, the shallow groove can be used to position the reflective paper.

[0012] Optionally, the cladding plate can be detachably mounted on the platform.

[0013] By adopting the above technical solution, the detachable coating plate can be easily replaced in the future.

[0014] Optionally, threaded holes are provided at the edges of the film-coated board, and threaded grooves are provided at the corresponding positions of the threaded holes on the platform. The threaded holes and threaded grooves are connected by connecting bolts.

[0015] By adopting the above technical solution, the threaded hole and the threaded groove are aligned, and the connecting bolt is inserted between them to achieve installation; at the same time, disassembly is also very convenient.

[0016] Optionally, each edge of the coated plate is provided with an iron insert, and each position on the platform corresponding to the iron insert is provided with a slot for inserting the iron insert. A magnetic piece is provided on the inner bottom wall of the slot, and the iron insert and the magnetic piece are attracted to each other by magnetism.

[0017] By adopting the above technical solution, after the iron insert is aligned and inserted into the slot, the iron insert and the magnetic piece are attracted by magnetism, which can make the film plate stand stably on the platform; and when disassembling, the iron insert can be directly removed from the slot, which is very convenient for disassembly and assembly.

[0018] Optionally, the impurity removal device includes an adsorption mechanism and a sliding support; the sliding support is mounted on a platform, and the adsorption mechanism is slidably mounted on the sliding support and located above the coating plate; the adsorption mechanism is used to adsorb the surface of the reflective paper.

[0019] By adopting the above technical solution, the adsorption mechanism can slide on the sliding support to achieve mobile operation, and can be changed according to different adsorption positions.

[0020] Optionally, the sliding bracket includes support rods and top sliding rods. Multiple support rods are arranged circumferentially on the platform around the film-coated plate. Two top sliding rods are arranged parallel to each other at the upper ends of the multiple support rods. A displacement plate is slidably arranged on the top sliding rod. A sliding sleeve is provided at the lower end of the displacement plate. The sliding sleeve is slidably fitted onto the top sliding rod. The adsorption mechanism is installed on the displacement plate.

[0021] By adopting the above technical solution, the displacement plate can move freely on the top sliding rod through the sliding sleeve, thereby achieving the effect of adjusting the position of the adsorption mechanism.

[0022] Optionally, the adsorption mechanism includes a dust collection component, a dust collection component, a gripping and opening / closing component, and a dust-end rebound and pulling component. The dust collection component is mounted on a displacement plate, the dust collection component is mounted on the dust collection component, the gripping and opening / closing component is mounted on the dust collection component, and the dust-end rebound and pulling component is mounted between the displacement plate and the dust collection component. The dust collection component is used to adsorb and store glass shards and dust on the surface of the reflective paper in the dust collection component. The gripping and opening / closing component is used for hand gripping to facilitate control of the position of the dust collection component, and the gripping and opening / closing component can activate the dust collection component while the hand is gripping it. The dust-end rebound and pulling component is used to automatically bring the dust collection component back to a position away from the reflective paper after adsorption is completed.

[0023] By adopting the above technical solution, the user first holds the holding and opening / closing component manually, and then pulls it downwards to bring the impurity suction component close to the reflective paper for adsorption. After adsorbing the glass shards and dust on the surface of the reflective paper, the impurity collection component collects the adsorbed glass shards and dust. After the operation is completed, the holding and opening / closing component is released. Under the rebound force of the rebound pulling component at the adsorption end, the impurity suction component will be brought back to a position away from the reflective paper, without affecting the normal lamination of the subsequent CG.

[0024] Optionally, the dust collection assembly includes a suction fan, a collection pipe, and a dust collection bag. The suction fan is mounted on the displacement plate, the collection pipe is connected to the air outlet end of the suction fan, and the dust collection bag is fitted onto the pipe opening end of the suction pipe.

The grip block is mounted on a pressing plate, the guide hollow tube passes through the grip block, and the bellows tube is inserted inside the guide hollow tube. The two side walls of the guide hollow tube are concave to allow the index finger and thumb to grip it. The grip block is also hollow inside, the telescopic button is horizontally inserted into the side wall of the grip block, and the rebound spring is located between the telescopic button and the inner wall of the grip block, always having a tendency to push the telescopic button horizontally outward from the grip block.

A battery is located on the lower wall of the displacement plate, the first conductive plate is electrically connected to the battery, and the second conductive plate is electrically connected to the suction fan.

[0028] By adopting the above technical solution, firstly, the person holds the object block with their hand, and passes their index and middle fingers through both sides of the guide hollow tube, clamping them against the concave side wall of the guide hollow tube, so that the index finger touches the end of the telescopic button located outside the holding block; then, a vertical downward force is applied to pull the pressing plate, bringing it closer to the surface of the reflective paper, so that the suction nozzle is aligned with the surface of the reflective paper; then, the index finger presses the telescopic button, causing the first conductive sheet and the second conductive sheet to adhere and conduct electricity, and the power of the battery is transferred to the suction fan, which generates suction, thereby causing the suction nozzle to also generate suction, sucking the residual glass shards and dust particles on the surface of the reflective paper into the dust collection bag for storage; after the suction is completed, the holding block is released, and under the action of the rebound spring, the pressing plate moves away from the reflective paper, achieving a convenient effect of adsorbing the residual glass shards and dust particles on the surface of the reflective paper.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0038] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0039] Example 1:

[0040] A suspended CG coating platform 1, referring to Figure 1 , 2 The system includes a platform 1 and a laminating plate 2. The surface area of ​​the platform 1 is larger than the surface area of ​​the laminating plate 2. The laminating plate 2 is installed on the surface of the platform 1. A suspended groove 21 is provided on the laminating plate 2 at the position corresponding to the CG ink coating. The groove 21 has a depth of 2mm and a width of 5mm. In this embodiment, two suspended grooves 21 are arranged on the surface of the laminating plate 2, and the length direction of the two suspended grooves 21 is consistent with the length direction of the laminating plate 2. It is worth noting that the suspended groove 21 is described as "established". In fact, in this embodiment, the suspended groove 21 is formed by deforming the laminating plate 2, so that the laminating plate 2 is no longer a general flat plate, but has depressions and protrusions on the surface. The depressions are the suspended grooves 21.

[0041] After the CG is attached to the laminating plate 2, the position of the CG ink coating is directly opposite the groove, so that the CG ink coating is not likely to come into direct contact with the surface of the laminating platform 1, reducing the occurrence of damage or scratches to the CG ink coating.

[0042] Combination Figure 2 The junction between the edge of the suspended groove 21 and the surface of the laminated plate 2 is smooth. A shallow receiving groove 22 is formed at this junction, with its length aligned with that of the laminated plate 2. Reflective paper 221 is placed within the shallow receiving groove 22. After the reflective paper 221 is placed at the junction of the suspended groove 21 and the laminated plate 2, it softens the image and improves the sharpness of the CCD camera image.

[0043] Reference Figure 2 Each edge of the coated plate 2 has threaded holes 23, and each position on the platform 1 corresponding to the threaded holes 23 has a threaded groove 11. The threaded holes 23 and the threaded grooves 11 are connected by connecting bolts 24. In this embodiment, the coated plate 2 is rectangular in shape, and the platform 1 is also rectangular in shape, so there are four threaded holes 23 and four threaded grooves 11. After aligning the threaded holes 23 and the threaded grooves 11, the connecting bolts 24 are inserted between them to complete the installation. At the same time, during disassembly, after unscrewing the connecting bolts 24 from the threaded holes 23 and the threaded grooves 11, the coated plate 2 can be easily removed from the platform 1, thus facilitating the replacement of a new coated plate 2.

[0044] Combination Figure 1 , 3Platform 1 is also equipped with a cleaning device 3, which is used to remove glass shards and dust particles remaining on the surface of reflective paper 221. Specifically, the cleaning device 3 includes an adsorption mechanism 4 and a sliding support 5. The sliding support 5 is installed on platform 1, and the adsorption mechanism 4 is slidably installed on the sliding support 5 and located above the film plate 2. The adsorption mechanism 4 is used to adsorb the surface of reflective paper 221.

[0045] Combination Figure 1 The sliding bracket 5 includes support rods 51 and top sliding rods 52. Multiple support rods 51 are arranged circumferentially on the platform 1 around the film-coated plate 2. In this embodiment, one support rod 51 is vertically arranged on each of the four outer corners of the film-coated plate 2; and one top sliding rod 52 is horizontally placed on top of two support rods 51, i.e., there are two top sliding rods 52. A displacement plate 6 is slidably mounted on the top sliding rod 52. Two sliding sleeves 61 are provided at the lower end of the displacement plate 6, with one sliding sleeve 61 corresponding to one top sliding rod 52. The sliding sleeves 61 are slidably fitted onto the top sliding rod 52. The adsorption mechanism 4 is mounted on the displacement plate 6. The displacement plate 6 can move freely on the top sliding rod 52 via the sliding sleeves 61, thereby achieving the effect of adjusting the position of the adsorption mechanism 4.

[0046] like Figure 1 , 3 As shown, the adsorption mechanism 4 includes a dust collection component 41, a dust collection component 42, a gripping and opening / closing component 43, and an adsorption end spring-loaded pull component 44. The dust collection component 41 is mounted on the displacement plate 6, the dust collection component 42 is mounted on the dust collection component 41, the gripping and opening / closing component 43 is mounted on the dust collection component 42, and the adsorption end spring-loaded pull component 44 is mounted between the displacement plate 6 and the dust collection component 42. The dust collection component 42 is used to adsorb and store glass shards and dust on the surface of the reflective paper in the dust collection component 41. The gripping and opening / closing component 43 is used for a person to hold and control the position of the dust collection component 42, and the gripping and opening / closing component 43 can activate the dust collection component 42 while the person is holding it. The adsorption end spring-loaded pull component 44 is used to automatically bring the dust collection component 42 back to a position away from the reflective paper 221 after adsorption is completed.

[0047] Reference Figure 3 Specifically, the dust collection assembly 41 includes a suction fan 411, a collection pipe 412, and a dust collection bag 413. The suction fan 411 is detachably connected to the upper surface of the displacement plate 6 by bolts. One end of the collection pipe 412 is connected to the air outlet end of the suction fan 411. The dust collection bag 413 is directly fitted onto the end of the collection pipe 412 away from the suction fan 411. In this embodiment, the dust collection bag 413 is a filter cloth bag. The surface of the filter cloth bag has many tiny pores, which can maintain the air pressure balance inside and outside the collection pipe 412 and retain the absorbed glass shards and dust particles inside.

[0048] Reference Figure 3 , 4 The vacuuming assembly 42 includes a bellows tube 421 and a nozzle 422. One end of the bellows tube 421 is connected to the air intake end of the vacuum fan 411, and the other end extends vertically downward after passing through the displacement plate 6. The bellows tube 421 itself is telescopic and can be lengthened or shortened. The nozzle 422 is installed on the end of the bellows tube 421 away from the vacuum fan 411. The nozzle 422 is a commonly used model in the vacuuming field.

[0049] Referring to Figure ×, the adsorption end rebound pulling assembly 44 includes a compression spring 441 and a pressing plate 442; multiple compression springs 441 are provided on both sides of the pressing plate 442. In this embodiment, the pressing plate 442 has a rectangular shape, and one compression spring 441 is provided at each of the four corners of the pressing plate 442; the end of the compression spring 441 away from the pressing plate 442 is connected to the lower plate surface of the displacement plate 6, and the compression spring 441 always has the tendency to pull the pressing plate 442 upward.

[0050] Reference Figure 3 , 4 The grip opening and closing assembly 43 includes a grip block 431, a guide hollow tube 432, a rebound spring 433, a telescopic button 434, a first conductive sheet 435, and a second conductive sheet 436. The grip block 431 is mounted on a pressing plate 442. The guide hollow tube 432 passes through the grip block 431, and an organ tube 434 is inserted inside the guide hollow tube 432. The two sides of the guide hollow tube 432 are concave to allow the index finger and thumb to grip it. The grip block 431 is also hollow inside. The telescopic button 434 is horizontally inserted into the side wall of the grip block 431. The rebound spring 435... 33 is disposed between the telescopic button 434 and the inner wall of the grip block 431. The return spring 433 always has the tendency to push the telescopic button 434 horizontally outward from the grip block 431. The first conductive sheet 435 is disposed on one end edge of the telescopic button 434 located inside the grip block 431. The second conductive sheet 436 is installed inside the grip block 431 and is directly opposite to the first conductive sheet 435. A storage battery 7 is disposed on the lower wall of the displacement plate 6. The first conductive sheet 435 is electrically connected to the storage battery 7 through a spring wire. The second conductive sheet 436 is also electrically connected to the suction fan 411 through a spring wire.

[0051] The implementation principle of this application embodiment is as follows: After the CCD camera takes a picture, the displacement plate 6 is manually moved above one of the reflective sheets 221. Then, the operator's hand is held on the grip block 431, and the index and middle fingers are passed through the two sides of the guide hollow tube 432 respectively. The index and middle fingers are clamped on the concave side wall of the guide hollow tube 432, and the index finger touches the end of the telescopic button 434 located outside the grip block 431. Then, the operator's five fingers are pressed on the side wall of the grip block 431. This makes it easier to grasp the grip block 431 and makes it easier to operate the pressing plate 442. At this point, apply vertical downward force to pull the pressing plate 442, bringing it closer to the surface of the reflective paper 221, so that the suction nozzle 422 is aligned with the surface of the reflective paper 221. Then, press the telescopic button 434 with your index finger to make the first conductive sheet 435 and the second conductive sheet 436 stick together and conduct electricity. The power of the battery 7 is transmitted to the suction fan 411, which generates suction, thereby making the suction nozzle 422 also generate suction, sucking the residual glass shards and dust particles on the surface of the reflective paper into the dust collection bag 413 for storage. After the adsorption is complete, release the holding block 431. Under the action of the rebound force of the return spring 433, the pressing plate 442 moves away from the reflective paper 221, achieving a more convenient effect of adsorbing the residual glass shards and dust particles on the surface of the reflective paper 221.

[0052] Example 2:

[0053] The difference between this embodiment and Embodiment 1 is that: Figure 5 As shown, each edge of the coated plate 2 is provided with an iron insert 25. Corresponding to the positions of the iron inserts 25 on the platform 1, there are corresponding slots 12 for inserting the iron inserts 25. A magnetic piece 121 is provided on the inner bottom wall of the slot 12, and the iron inserts 25 and the magnetic piece 121 are attracted to each other magnetically. After the iron inserts 25 are aligned and inserted into the slots 12, the magnetic attraction between the iron inserts 25 and the magnetic piece 121 allows the coated plate 2 to remain stably on the platform 1. Disassembly is very convenient; the iron inserts 25 can be simply removed from the slots 12.
