Description

Technical Field

[0001] The present invention relates to the field of display screen laminating equipment, in particular to a mobile phone display screen laminating equipment and a laminating method. Background Art

[0002] As an important part of smart phones, mobile phone displays not only carry the function of displaying images and texts, but also directly affect the user's visual experience and interactive feelings. Display screen bonding is a crucial link in the manufacturing process, which is directly related to the final performance and appearance of the display screen. Display screen bonding refers to the process of tightly combining the various components of the display screen (such as substrate, protective glass, touch screen, display screen, etc.) through specific materials and processes. This process not only requires that the components are tightly and seamlessly connected, but also needs to consider the performance of multiple aspects such as display effect, shock resistance, waterproof and dustproof.

[0003] Currently, the basic method of laminating mobile phone displays is manual lamination. In some cases, non-permanent lamination methods are used for screen observation or temporary repair. These methods do not require traditional glue. For example, special fastening measures or snap-on structures can be used to temporarily fix the screen assembly for observation or evaluation. However, during non-permanent lamination, the screen to be bonded is easily contaminated by dust particles in the air, which in turn causes the screen to be contaminated. If the dust is not found in time after the screen is bonded and assembled, the screen will continue to be bonded, which will affect the observation in the future. It will be more time-consuming and laborious to disassemble and clean the dust.

[0017] The present application also discloses a method for laminating a mobile phone display screen, which is applied to a laminating device for a mobile phone display screen, and comprises the following steps:

[0018] Place the screen body to be bonded on the screen pressing and dust removal assembly;

[0019] The screen body is sucked from the screen suction port by the liftable screen pressing component, and then the sucked screen body is sent to the flippable laminating support seat along the screen pressing port;

[0020] The flip-fitting support can be flipped after receiving the screen body, and cooperate with the fitting detection component to perform inspection after each screen body fitting.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present application provides a screen pressing and dust removal component, a reversible laminating support, and a laminating detection component, so that the screen can be cleaned before laminating, and then the laminating can be carried out after the cleaning is completed. After the screen is laminating is completed, the reversible laminating support is turned 90 degrees together with the newly delivered screen so that the staff can check whether there are defects such as dust on the screen. When defects are found, the screen delivered this time is directly taken out, and then the screen is replaced or cleaned. The screen is checked once each time it is laminated, thereby effectively avoiding the situation where no dust is found after the screen is laminated and other screens are continued to be laminated, which will cause subsequent disassembly to be more time-consuming and labor-intensive. The whole process can effectively improve the quality of the finished product of non-permanent lamination of display screens and avoid the impact of dust on the observation results on the display screen.

[0023] 2. The present application provides a flippable bonding support, which can face the support front upward to align with the screen pressing opening for easy bonding when the screen is bonded. When the newly bonded screen is subsequently tested, the support can be directly flipped 90 degrees to one side. The whole process is simple and efficient. In addition, the stabilization mechanism on the flippable bonding support can effectively improve the stability of the support when the support front is facing upward and after the support is flipped 90 degrees to one side.

[0024] 3. The bonding detection component of the present application can erect a magnifying glass in front of the bearing seat and a film viewing light behind the bearing seat after the bearing seat is flipped ninety degrees to one side. At this time, the film viewing light, the bearing seat, the magnifying glass and the observation window are on the same horizontal axis. The film viewing light illuminates the rear end of the bearing seat to facilitate staff to observe from the front, and the magnifying glass magnifies the observation area to assist staff to observe better. In addition, when there is no need to inspect the screen but to bond the screen, the falling of the film viewing light and the magnifying glass does not affect the viewing of the bonding process from the observation window.

[0025] 4. The screen pressing and dust removing component of the present application can clean the screen to be pressed in before the screen is bonded. When in use, after the screen in the first screen placing groove is taken out and sent into the supporting seat, the strip plate moves forward a unit distance (i.e., the distance between the second through groove and the adjacent cleaning groove), so that the cleaning soft glue in the first cleaning groove is blocked under the screen pressing mouth. Subsequently, during the bonding process, the screen is pressed against the cleaning soft glue for cleaning, and after the cleaning is completed, the strip plate is moved forward a unit distance again to facilitate the screen to pass through the strip plate along the second through groove and be pressed down into the screen body slot. In addition, during this process, the screen in the second screen placing groove reaches below the screen suction mouth, and the first screen placing groove extends out of the chamber from the strip groove, and so on until all the screens are pressed into the screen body slots to complete non-permanent bonding, and all the screen placing grooves are also extended to facilitate the next placement of the screen, which is easy to use.

[0026] 5. The liftable screen pressing assembly of the present application can quickly and stably press the screen into the screen card slot. Compared with the traditional lifting mechanism, the liftable screen pressing assembly has a more compact structure and more efficient lifting. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The working principle of the present invention is: when in use, first, start the second linear motor 58, and the second linear motor 58 runs along the second linear guide rail 57 to push the strip plate 60 out of the strip groove 61. Then, the screen bodies to be pressed in are placed in each screen placement groove 64 in order, and then the cleaning soft glue 66 is placed in the cleaning groove 56 and fixed, and then the second linear motor 58 runs in reverse to retract the strip plate 60 into the chamber 23. Then, by running the first linear motor 4, the lifting and lowering screen pressing assembly slowly moves forward along the first linear guide rail 3 until the negative pressure suction plate 22 reaches just above the screen suction port 24, and then, the negative pressure suction plate 22 is lowered. At this time, the external negative pressure device connected to the negative pressure suction plate 22 is running, and after the negative pressure suction plate 22 contacts the screen body in the first screen placement groove 64, the negative pressure suction plate 22 adsorbs the screen body. Then the negative pressure suction plate 22 is raised together with the screen body, and after the screen body in the first screen placement slot 64 is taken out for screen bonding, the strip plate 60 is moved forward by a unit distance (i.e., the distance between the second through slot 65 and the adjacent cleaning slot 56) through the second linear motor 58, so that the cleaning soft glue 66 in the first cleaning slot 56 is blocked below the screen pressing opening 25. Then the negative pressure suction plate 22 is moved to just above the screen pressing opening 25 through the first linear motor 4, and the negative pressure suction plate 22 is lowered. During the process, the screen body is against the cleaning soft glue 66, and the cleaning soft glue 66 absorbs the dust particles on the bottom surface of the screen body to achieve a cleaning effect, while the top surface of the screen body is sucked by the negative pressure suction plate 22 and will not be contaminated with dust. After cleaning is completed, the strip plate 60 is moved forward a unit distance again to facilitate the screen body to pass through the strip plate 60 and press down into the screen body slot 40 of the bearing seat 33. After the screen body is pressed into the bottom of the screen body slot 40, the external negative pressure device is stopped, and the negative pressure suction plate 22 no longer adsorbs the screen body. At this time, the screen body in the second screen placement slot 64 reaches below the screen suction port 24, and the first screen placement slot 64 extends from the strip groove 61 to the chamber 23, and so on until all screen bodies are pressed into the screen body slot 40 to complete non-permanent bonding, and all screen placement slots 64 are also extended to facilitate the next placement of the screen body for easy use. It should be noted that the screen body pressed into the screen body slot 40 for bonding is clamped and limited by the preset physical buckles between the screen bodies and the rubber pads 41 embedded in the inner wall of the screen body slot 40.

[0050] The first stepping motor 31 rotates the first gear 43 and the first worm 45 rotates with the first shaft 44. At the same time, the second worm 46 and the third worm 51 on the first shaft 44 rotate synchronously, and the second gear 48 and the third shaft 52 also rotate accordingly, and the second shaft 47 and the third shaft 52 also rotate accordingly. At this time, the film viewing light connector 54 and the film viewing light 55 rotate ninety degrees and are upright behind the bearing seat 33, while the magnifying glass connector 49 and the magnifying glass 50 rotate ninety degrees and are upright in front of the bearing seat 33. The film viewing light 55, the bearing seat 33, the magnifying glass 50 and the observation window 26 are on the same horizontal axis. The film viewing light 55 illuminates the rear end of the bearing seat 33 to facilitate observation by the staff from the front, while the magnifying glass 50 magnifies the observation area to assist the staff in better observation. In addition, when the screen body does not need to be inspected but the screen body is bonded for assembly, the film viewing lamp 55 and the magnifying glass 50 fall down without affecting the bonding process from the observation window 26, and the flat glass 27 prevents dust from entering the chamber 23 without affecting the observation function of the observation window 26. It should be noted that when the bearing seat 33 is in a horizontal state, it contacts the first electromagnet 37 of the stabilizing seat 36, and the first electromagnet 37 and the power supply 39 are energized to generate magnetic adsorption to fix the bearing seat 33, and the bearing seat 33 rotates ninety degrees and contacts the second electromagnet 38, and the second electromagnet 38 and the power supply 39 are energized to generate magnetic adsorption to fix the bearing seat 33. Among them, the first worm 45 has opposite thread rotation directions to the second worm 46 and the third worm 51.

[0051] After the inspection is completed, if it is found that the screen body that has been pressed and bonded has defects, the next screen bonding will be stopped in time, and the screen body that has just been bonded will be removed (the specific disassembly method is to open the working door reserved in the chamber 23 and manually remove the screen body that has just been bonded) for replacement or cleaning. If there are no defects, the supporting seat 33 will be erected to bond the next screen body. After all the screen bodies are pressed and bonded, the entire display screen module is adsorbed by the negative pressure suction plate 22 and pulled out from the screen placement groove 64, and the non-permanently bonded display screen module is observed as a whole. It should be noted that the specific process of the negative pressure suction plate 22 rising and falling is as follows: the second rotary stepping motor 14 drives the upper pulley 10 to rotate, and the synchronous belt 12 moves with the cooperation of the lower pulley 11. During the process, the connecting seat 15, the transverse connecting plate 16, the longitudinal connecting plate 17, the lifting plate 18, the second L-shaped plate 21 and the negative pressure suction plate 22 are lifted up and down, and the coordinated use of the optical axis 7 and the linear bearing 19 can improve the stability of the lifting plate 18 when it is lifted up and down.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
