Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone glass cover plate storage boxes, and in particular to a mobile phone glass cover plate safety storage box. Background Art

[0002] Mobile phone glass cover, also known as strengthened optical glass, glass window, strengthened mobile phone lens, etc., is the outermost layer of the touch screen that protects the material and is located above the mobile phone display. The main raw material of mobile phone glass cover is ultra-thin flat glass. After cutting, CNC carving, thinning, strengthening, coating, printing and other processes, the mobile phone glass cover produced has the functions of anti-impact, scratch resistance, oil resistance, anti-fingerprint, and enhanced light transmittance.

[0003] Mobile phone glass cover plates mainly include: 2D mobile phone glass cover plates, 2.5D mobile phone glass cover plates and 3D mobile phone glass cover plates. Among them, 2D mobile phone glass cover plates are purely flat glass cover plates without any curved design. Due to the advantages of 2D glass cover plates in cost, production technology and market demand, they still maintain great competitiveness in the mid- and low-end smartphones and other digital product markets.

[0004] In the production process, 2D mobile phone glass cover plates need to go through the sampling and inspection stage. During this process, the safe storage box plays a key role in storing samples. The traditional storage method includes placing the cover plate flat in the box or directly inserting it into the preset slot of the box body. However, in the inspection process, the cover plate will inevitably come into contact with the inner wall of the box body and may rub against each other due to the shaking caused by movement. The edge areas of the cover plate are extremely susceptible to damage, especially these edge areas. Due to the stress concentration effect, they are more likely to break, thereby increasing the risk of cover plate breakage or damage, which in turn affects subsequent inspection work.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] like Figure 1 - Fig.13 As shown, the present invention provides:

[0054] A mobile phone glass cover safety storage box includes a box body 10. At least one partition 20 is installed in the box body 10. The upper surface of the partition 20 and the inner bottom wall of the box body 10 are equipped with an airbag unit 40 by opening a bottom groove 30. At least two storage units 50 corresponding to the bottom groove 30 are installed on the inner wall of the box body 10. Preferably, a flexible protective pad is provided on the inner wall of the box body 10.

[0055] like Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, the storage unit 50 includes a platform plate 51 rotatably connected to the box body 10, and at least four through holes 52 are formed on the platform plate 51. A vacuum suction cup 53 whose bottom end is connected to the mounting seat 41 located above is inserted into the through hole 52, and the plurality of vacuum suction cups 53 are connected together through a connecting pipe 54 provided on the outer wall.

[0056] The airbag unit 40 includes two mounting seats 41, a main airbag 42 is fixed between the two mounting seats 41, and an adjustment rod group 43 for the deployment height of the main airbag 42 is mounted on the main airbag 42, and the upper surface of the upper mounting seat 41 contacts the lower surface of the platform plate 51;

[0057] The main airbag 42 is height-adjusted under the drive of the adjustment rod group 43, which can drive the vacuum suction cup 53 group located on the outside to lift upward, thereby driving the mobile phone glass cover to slide into the box body 10 by itself when stored, and be fixed by the vacuum suction cup 53, and at the same time, the vacuum suction cup 53 group located on the inside can be lifted upward, and the vacuum suction cup 53 can release the fixation of the mobile phone glass cover, so that it can slide out by itself;

[0058] like Figure 2 , Figure 3 and Fig.10 As shown, the adjusting rod group 43 includes a retaining seat 431 fixed to the lower surface of the mounting seat 41 located above, a slot is provided at the center of the inner bottom wall of the retaining seat 431 and the center of the mounting seat 41 located above, a sealing ring is provided on the inner wall of the slot, a guide cylinder 432 is inserted in the sealing ring, a first spring 433 is sleeved on the outer surface of the guide cylinder 432, and the bottom end of the first spring 433 is fixed to the mounting seat 41 located below through a buffer pad;

[0059] A guide groove is provided in the middle of both side walls of the bottom groove 30, in which a T-shaped cross bar 436 is inserted, and two long cross bars 437 are overlapped on the T-shaped cross bar 436, and a middle lifting frame 438 is fixed to both ends of the T-shaped cross bar 436, and a front lifting frame 439 and a rear lifting frame 4310 are fixed to both ends of the two long cross bars 437, respectively. The middle lifting frame 438, the front lifting frame 439 and the rear lifting frame 4310 are all slidably installed on the outer wall of the box body 10 through a slider to prevent the three from tilting during the up and down movement, so as to ensure that they can always move in the vertical direction;

[0060] like Figure 4 and Figure 5 As shown, an extension rod 435 is fixed on each of the two long cross bars 437, and the main airbags 42 are distributed in groups of two. A connecting rod 434 is fixed to the middle of the outer wall of each group of main airbags 42. The two ends of the connecting rod 434 inserted into the two main airbags 42 are respectively fixed to the two guide cylinders 432, and one end of the extension rod 435 is fixed to the connecting rod 434 on each group of main airbags 42.

[0061] Specifically, when it is necessary to put the randomly selected samples into the box body 10, the front pulling frame 439 is pulled upward to make the long cross bar 437 located on the front side drive the extension rod 435 fixed on its surface to move upward, thereby driving the connecting rod 434 to move upward. While moving upward, the connecting rod 434 will gradually abut against the vacuum suction cup 53, and continue to drive it to move upward after abutting against the top, at which time the main airbag 42 located on the front side will be driven to rise, thereby driving the front end of the platform plate 51 to tilt upward. It is worth noting that the tilting height can be adjusted as needed. After the 2D mobile phone glass cover is placed, the glass cover can slide inwards by itself. After the glass cover is completely slid into the box body 10, the front pull frame 439 is moved downward again to reset it, thereby driving the main airbag 42, the platform plate 51 and the vacuum suction cup 53 to return to a horizontal state. At this time, the glass cover is stably placed on the surface of the vacuum suction cup 53.

[0062] The lower surfaces of the middle lifting frame 438, the front lifting frame 439 and the rear lifting frame 4310 are all fixed with positioning tubes 44, and positioning rods 45 are inserted into the positioning tubes 44. External convex cylinders 46 are fixed on both sides of the positioning tubes 44 through through holes, and hemispherical columns 47 are fixed in the external convex cylinders 46 through second springs. Multiple positioning holes matching the hemispherical columns 47 are opened on both sides of the positioning tubes 44. The hemispherical columns 47 are engaged in the positioning holes under the drive of the second spring, so that the middle lifting frame 438, the front lifting frame 439 and the rear lifting frame 4310 can be fixed in position after moving;

[0063] During the process of the middle lifting frame 438, the front lifting frame 439 and the rear lifting frame 4310 moving up and down, when the movement stops, the second spring drives the hemispherical column 47 to engage into the positioning hole at the corresponding position, thereby fixing the positions of the middle lifting frame 438, the front lifting frame 439 and the rear lifting frame 4310 after the movement;

[0064] like Figure 2 , Figure 4 and Figure 7 As shown, the vacuum suction cup 53 includes a suction cup handle 531, a suction cup head 532 is detachably fixed to the top of the suction cup handle 531, a connecting pipe 54 is fixedly connected to the suction cup handle 531, a fixing ring is fixed to the bottom of the suction cup handle 531, a plurality of screws are arranged on the fixing ring, the suction cup handle 531 is fixed to the surface of the mounting seat 41 located above by screws, an annular air bag 533 is sleeved on the top of the outer surface of the suction cup handle 531, the annular air bag 533 can fill the gap between the suction cup handle 531 and the inner wall of the through hole 52, so that during the transfer process, the shaking of the suction cup handle 531 can be buffered and its shaking amplitude can be reduced to improve stability, the outer wall of the annular air bag 533 is connected to the inner wall of the through hole 52, a sealing ring 537 is fixed at the edge of the upper surface of the suction cup head 532, and the sealing ring 537 can enable the 2D mobile phone glass cover to slide smoothly on the suction cup head 532;

[0065] A micro air pump 55 is mounted on the inner bottom wall of the bottom tank 30, a power slot is provided on one side wall of the bottom tank 30, a battery is mounted in the power slot, and the micro air pump 55 can be powered by the battery. A three-way solenoid valve 56 is fixedly connected to the air extraction end of the micro air pump 55, and both ends of the three-way solenoid valve 56 are fixedly connected to branch pipes, one end of the branch pipe is connected to one end of the connecting pipe 54 that penetrates into the bottom tank 30, and the air extraction end of the micro air pump 55 is connected to the connecting pipe 54 through the branch pipe.

[0066] When the mobile phone glass cover slides in and is in a horizontal state, the micro vacuum pump 55 is started, and the suction cup head 532 is evacuated through the branch pipe and the connecting pipe 54, so that negative pressure is generated between the suction cup head 532 and the 2D mobile phone glass cover, and the 2D mobile phone glass cover is adsorbed and fixed on the suction cup head 532.

[0067] like Figure 7 As shown, an air inlet hole is opened at the bottom end of the suction cup handle 531, a limiting ring 534 is fixed on the inner wall of the suction cup handle 531, and a sealing seat 536 for sealing the air inlet hole is fixed to the lower surface of the limiting ring 534 through a third spring 535;

[0068] One end of the guide tube 432 that penetrates into the air inlet is fixed to the hole sealing seat 536. A plurality of air outlet holes are provided on the top of the outer wall of the guide tube 432. A gap is left between the hole sealing seat 536 and the inner wall of the suction cup handle 531.

[0069] When it is necessary to take out the stored 2D mobile phone glass cover plate sample for testing, first pull the middle lifting frame 438 upwards to move the T-shaped cross bar 436 upwards, and drive the long cross bar 437 to move upwards together. At the same time, the connecting rod 434 is driven upwards by the extension rod 435, so that the guide cylinder 432 moves upwards, gradually pushing the sealing seat 536 upwards to release the seal of the air inlet hole. At this time, the gas in the main air bag 42 enters the suction cup handle 531 through the air outlet on the outer wall of the guide cylinder 432, and then enters the suction cup head 532, thereby releasing the negative pressure adsorption effect of the suction cup head 532 on the mobile phone glass cover plate. At this time, stop moving the middle lifting frame 438, and instead pull the rear lifting frame 4310 upwards, so that it drives the main air bag 42 at the rear side to rise, and then drives the suction cup head 532 at the rear side to gradually be higher than the front side, so that the front side of the cover plate is tilted downward, so that the cover plate can slide outward, which is convenient for people to take.

[0070] Specifically, when the mobile phone glass cover plate safety storage box is working / in use:

[0071] First, in the initial state, the platform plate 51 and the suction cup head 532 are in a horizontal state. When the extracted 2D mobile phone glass cover plate to be inspected needs to be placed in the box body 10, the front pull frame 439 is pulled upward to make the long cross bar 437 located on the front side drive the extension rod 435 fixed on its surface to move upward together, thereby driving the connecting rod 434 to move upward. While moving upward, the connecting rod 434 will gradually abut against the vacuum suction cup 53, and continue to drive it to move upward after abutting against the top, at this time, the main airbag 42 located on the front side will be driven to rise, and then the front end of the platform plate 51 will be driven to tilt upward. After tilting, the platform plate 51 will tilt accordingly. While tilting, the vacuum suction cup 53 on the front side will move upward together, and then a drop will be generated with the vacuum suction cup 53 on the rear side, and the surfaces of the two will form an inward tilt;

[0072] At this time, when the 2D mobile phone glass cover is placed on the surface of the suction cup head 532, the glass cover can slide inward by itself under the action of the inclined surface. After the glass cover is completely slid into the box body 10, the front pull frame 439 is moved downward again to reset it, thereby driving the main air bag 42, the platform plate 51 and the vacuum suction cup 53 to return to a horizontal state. At this time, the glass cover is stably placed on the surface of the vacuum suction cup 53, and then the micro air pump 55 is started. The suction end of the micro pump 55 is used to vacuum the suction cup head 532 through the branch pipe and the connecting pipe 54, so that a negative pressure is generated between the suction cup head 532 and the 2D mobile phone glass cover, so that the 2D mobile phone glass cover is adsorbed and fixed on the suction cup head 532, thereby preventing the cover from shaking during the transfer process;

[0073] When it moves to the detection position, the middle lifting frame 438 is first pulled upward to move the T-shaped cross bar 436 upward, and the long cross bar 437 is driven to move upward together. At the same time, the connecting rod 434 is driven upward through the extension rod 435, so that the guide cylinder 432 moves upward, gradually pushing the sealing seat 536 upward to release the seal of the air inlet. At this time, the gas in the main airbag 42 enters the suction cup handle 531 through the air outlet on the outer wall of the guide cylinder 432, and then enters the suction cup head 532, thereby releasing the suction. The suction cup head 532 generates negative pressure adsorption on the mobile phone glass cover plate. At this time, the moving lifting frame 438 is stopped, and the rear lifting frame 4310 is pulled upward. During the upward movement, the guide cylinder 432 in the rear main airbag 42 moves to the point where the third spring 535 can no longer be compressed. At this time, the rear suction cup head 532 is pushed to tilt upward, and then forms a state of tilting forward and downward with the front suction cup head 532. At this time, the cover plate is tilted together, and then the cover plate is driven to slide out smoothly, which is convenient for quick removal during inspection;

[0074] When storing and using the device next time, the platform plate 51 and the suction cup head 532 can be restored to a horizontal state.

[0075] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
