Description

Background Art

[0001] Mobile electronic devices such as (but not limited to) tablet computers, mobile phones, mobile smartphones, and gaming devices have become increasingly common. Such mobile electronic devices have screen displays and / or glass back outer layers that are relatively easy to chip and crack when the mobile electronic device is accidentally dropped. These devices are also relatively easy to be scratched if rubbed by sharp or hard objects.

[0002] Repair and / or refurbishment of a cracked or scratched mobile electronic device screen broadly involves first separating the LCD / OLED (liquid crystal display / organic light emitting diode) or other type of display screen from the cracked outer glass, and then laminating the new glass layer onto the existing LCD / OLED screen. The lamination and debubbling process generally involves aligning, positioning and placing the replacement outer glass and adhesive layer onto the existing LCD / OLED screen, placing them into a vacuum pressure chamber, creating a vacuum within the vacuum pressure chamber, applying pressure so that the replacement outer glass adheres to the existing LCD / OLED screen, and then applying air pressure to remove bubbles or gaps that may have formed between the replacement outer glass and the existing LCD / OLED screen. This process should be the same if one wishes to assemble their own mobile electronic device screen display by purchasing the LCD / OLED screen display and outer glass separately, and then laminating and debubbling the LCD / OLED screen display and outer glass together.

[0003] Molds for aligning, positioning and placing a replacement outer layer of glass with an adhesive layer on an LCD / OLED screen are known in the art. The main difficulty encountered when using such existing molds is that the outer layer of glass cannot be perfectly aligned, positioned and placed on the LCD / OLED screen display due to very small but significant size inefficiencies and / or due to inefficient alignment and placement processes, resulting in cracked and / or uneven glass when laminated to the LCD / OLED screen display and / or the formation of large bubbles or gaps between the outer glass, adhesive and LCD / OLED screen display that cannot be or is extremely difficult to remove.

[0004] Machines for laminating the outer layer of glass with an adhesive layer onto the LCD / OLED screen and for removing bubbles ("debubbling") that may form between the outer glass, adhesive and LCD / OLED screen display are also known in the art. These machines are single machine units with separate chambers for lamination and separate chambers for debubbling, and the user of such machines first places the mold and the outer glass layer, adhesive layer and LCD / OLED screen display into the lamination chamber, and once the lamination process is complete, the laminated screen display is taken out, and then the laminated screen display is placed into the debubbling chamber. This takes more time and involves two processes and more user actions and efforts. In addition, having two chambers in one machine causes the machine to be bulky, takes up space, consumes higher power and is also heavier.

[0005] Machines for laminating an outer glass layer with an adhesive layer onto an LCD / OLED screen are also known in the art. These machines only have a laminating chamber and cannot remove bubbles or gaps that may form between the outer glass layer, adhesive layer, and LCD / OLED screen during the lamination process, thus involving the user purchasing a second machine that can remove the bubbles or gaps, and during the repair / refurbishment process, the user transfers the laminated mobile electronic device screen from the laminating machine to a debubbling machine, which involves more steps, time, and technician work. These laminating machines are also large, take up a lot of space, and are heavy.

[0006] The machines mentioned above apply the pressure required for the lamination process using either an air bladder that is inflated in the lamination chamber or a piston that applies pressure to an object placed in the lamination chamber. The air bladder method or the piston method does not always have a high success rate for perfect lamination.

[0007] Machines for removing bubbles and gaps formed between the outer glass, adhesive and LCD / OLED screen display ("debubbling") are also known in the art. These machines only have a "debubbling" chamber and cannot be used to laminate the outer glass layer with the adhesive layer onto the LCD / OLED screen, so a second machine is used that can perform the lamination process. During the repair / refurbishment process, the user transfers the laminated mobile electronic device screen from the laminating machine to the debubbling machine, which involves more steps, time and technician work. These debubbling machines are also large, take up a lot of space, and are heavy.

[0008] The performance of the machine mentioned above may be affected by the atmospheric pressure of the location where the machine is operated. This will result in poor performance due to incorrect pressure being applied during machine operation and if the user wishes to prevent this, the user will be serviced by a qualified professional who performs an on-site atmospheric pressure test and afterwards performs machine calibration and setting changes to ensure the machine is adapted to the machine's location atmospheric pressure. This is a costly exercise and qualified professionals may not be easy to find and if this work is not performed, poor machine performance and repair / refurbishment results will result.

[0009] New models of mobile electronic devices are released regularly. In order to repair / refurbish the broken or scratched screen displays of such new models, the above-mentioned machines need to be frequently set up and software upgraded, because each screen display is unique and may involve different settings regarding pressure, timing, and repair steps in order to achieve a successful repair / refurbishment. Frequent setup and software upgrades involve field software upgrades and may even change mechanical settings. If performed regularly, it is a costly, time-intensive and difficult task. If not performed correctly, the upgrades will result in repair / refurbishment failures. If not performed regularly, the upgrades will result in the machine not being optimized for performing repair / refurbishment on new mobile electronic device screen models, resulting in poor repair / refurbishment results.

[0010] Other difficulties encountered with the machines referenced above are that the machines are not connected via the Internet to a central computer server that hosts and operates the web-centric and / or mobile application software application, whereby the owner of one or more machines cannot remotely update one or more machine software and settings and / or remotely control the real-time operation of one or more machines and / or remotely activate and deactivate one or more machines and / or instantly remotely access real-time or historical information regarding the operation of such machines, repairs performed by such machines, repairs per mobile electronic device model, repairs performed by each technician, repairs performed per time period, repairs performed per location, repairs per grouped mobile electronic device model, technicians, time periods and locations, repair / refurbishment success rates, repair times, mobile electronic device models repaired, technician identities, machine defects, incorrect machine settings, user-identified machine defaults, consumables and parts, and cannot immediately order such items via the central computer server that hosts and operates the web-centric and / or mobile application software application.

[0059] The present technology may be best understood by referring to the following description taken in conjunction with the accompanying drawings.

[0060] Now go to Figures 1A to 1L, various views of a system (particularly a machine unit 30) according to one or more aspects of the present technology are shown. The rear housing panel 16, the front housing panel 19, the bottom housing base 3, the left side panel 18, the right side panel 20, the metal vacuum pressure chamber 24 and four steel columns 25 are shown. The top ends of the four steel columns 25 are screwed to the four corners of the metal vacuum pressure chamber 24, and the bottom ends of the four steel columns 25 are screwed to the four corners of the bottom housing base 3. The front housing panel 19, the rear housing panel 16, the left side panel 18, and the right side panel 20 are then clamped or screwed to the four steel columns 25 to form a machine housing.

[0061] The metal vacuum pressure chamber 24 has several features and functions. The metal vacuum pressure chamber 24 can be used to form a machine structure as described in the above paragraph. The metal vacuum pressure chamber 24 can be used as a lamination and defoaming chamber, and the outer glass layer 54, adhesive 56, LCD / OLED screen 53 and lamination mold 49 or other items for lamination and / or defoaming are placed in the chamber for lamination and / or defoaming. The metal vacuum pressure chamber 24 can be used to send air into and out of the airbag 13 via the airbag air port 26. The metal vacuum pressure chamber 24 has four holes through which the actuator 6 is passed to allow the actuator to be connected to the metal cover 15. The metal vacuum pressure chamber 24 has a hole that allows the metal cover wire rod 11 to pass through and also accommodates the cover sensor 27. Those skilled in the art will recognize that various types of metals or compounds can be used to make the metal vacuum pressure chamber 24.

[0062] A vacuum pump 1 is also shown. The vacuum pump 1 is used to suck all the air out of the metal vacuum pressure chamber, thereby creating a vacuum during the mobile electronic device screen lamination process. A vacuum pump bracket 2 is also shown. The vacuum pump bracket is used to mount the vacuum pump 1 to the bottom housing base 3 and hold the vacuum pump 1 firmly in place. Those skilled in the art will recognize that the vacuum pump can also be located outside the machine unit and can be connected to the machine unit via a second air inlet port located above the air inlet port 40. A piston chamber 21 that accommodates a piston (not shown) is also shown. The piston chamber 21 is used to drive the piston and the piston plate 10 attached to the piston (not shown) up and down during the lamination process. Attached to the piston chamber 21 is a piston chamber column 29, which is used to attach the piston chamber 21 to the bottom housing base 3.

[0063] A machine cooling fan 17 is also shown. The machine cooling fan 17 is used to cool the vacuum pump 1 and for cooling the internal area of ​​the machine housing. Those skilled in the art will recognize that if the vacuum pump 1 is located outside the machine unit 30, the machine cooling fan 17 can be removed from the machine unit 30. An electronic LCD / OLED screen display 8 is also shown. The electronic LCD display is used to display network, operating and functional data and information to the user of the machine unit 30 and is also used for on-site physical operation and control of the machine unit 30. Operation buttons 7 are also shown, which are used to start and stop certain operations and functions of the machine unit 30.

[0064] Also shown is a central air distribution block 4 having a solenoid valve 5. The central air distribution block 4 is used to receive air from an external air compressor 31 and distribute the air into and out of the metal vacuum pressure chamber 24, the piston chamber 21, and the air bag 13 via the solenoid valve 5, the pipeline, and the air passage. The solenoid valve 5 is used to open and close the passage for air to enter and leave the central air distribution block 4 and the metal vacuum pressure chamber 24, the piston chamber 21, and the air bag 13, and also allow air to exit the central air distribution block 4 and enter the atmosphere. Those skilled in the art will recognize that more than one central air distribution block 4 can be installed and used in the machine unit 30, and the number, size, and specifications of the solenoid valves on the central air distribution block 4 can vary depending on the system specification performance requirements.

[0065] O-ring 9 is also shown. O-ring 9 is used to airtightly seal the metal vacuum pressure chamber during the lamination and defoaming process. Those skilled in the art will recognize that the O-ring can be made of various types of high-pressure sealing rubber materials or other high-pressure sealing materials. Safety switch bracket 12 is also shown. The safety switch bracket 12 is attached to the underside of the metal cover with double-sided adhesive foam (not shown) and is used to trigger the closed safety switches 14 located on the four corners on the underside of the metal cover 15. In the case where the metal cover 15 is closing and fingers or other objects hinder the closing of the metal cover 15, the metal cover 15 will push the safety switch bracket 12, which will then cause the safety switch bracket 12 to press against one or more of the closed safety switches 14, thereby causing the metal cover 15 to stop closing and rise immediately. Airbag 13 is also shown. The airbag 13 is used to inflate in the metal vacuum pressure chamber 24 during the lamination process so as to apply downward pressure to the items placed in the metal vacuum pressure chamber 24 for lamination. Those skilled in the art will recognize that the airbag 13 can be made of latex or any other high expansion and contraction material. An airbag bracket is also shown as 28 for mounting and holding the airbag on the lower side of the metal cover 15. A metal cover 15 is also shown. The metal cover 15 has several features and functions. The metal cover 15 can be used to accommodate the airbag 13. The metal cover 15 can be used to accommodate 4 closed safety switches 14. The metal cover 15 can be used to open and close the metal vacuum pressure chamber 24. The metal cover 15 can be used to air-seal the metal vacuum pressure chamber. The metal cover 15 has an air channel that allows air to enter and leave the airbag air port 26 and enter and leave the airbag 13 for airbag inflation and deflation purposes, and the safety switch bracket 12 is also attached to the lower side of the metal cover 15, thereby supporting safety during the metal cover 15 closing process. Those skilled in the art will recognize that the metal cover 15 can be made of various metals or metal compounds, but are affected by the strength, weight and density of the metal or metal compound. Four actuators 6 are also shown. These four actuators have several features and functions. The actuators are used to lift the metal cover 15 upward and downward and to maintain the metal cover 15, the O-ring 9 and the metal vacuum pressure chamber 24 tightly pressed against each other so as to obtain a perfect airtight seal of the metal vacuum pressure chamber 24 and maintain this airtight seal during the vacuum and lamination process. Also shown are the cover sensor 27 and the cover magnet 23, which are used to provide a signal to the control printed circuit board 33 with a processor and operating system software so that when the metal cover 15 has reached the correct closed position, the actuator 6 can stop applying downward force to the metal cover 15.

[0066] Also shown is an external air compressor 31. The external air compressor is used to supply air at high pressure to the central air distribution block 4, which then distributes the air to the piston chamber 21, the air bag 13 and the metal vacuum pressure chamber 24 using the solenoid valve 5.

[0067] Also shown is a communication printed circuit board (PCB) 34 (with built-in processor and operating system software, not shown). The communication printed circuit board has a built-in processor and operating system software that acts as a bridge to provide Internet two-way data and command communication between the control printed circuit board 33 and the central computer server 32 that hosts and operates network-centric and / or mobile application software applications, platforms and databases. Those skilled in the art will recognize that the communication printed circuit board 34 can be installed in various locations within the machine unit 30.

[0068] Also shown is an external central computer server 32. The central computer server 32 hosts and operates a web-centric and / or mobile application software application, platform and database (not shown) and is connected to the communication printed circuit board 34 and then to the control printed circuit board 33 via the Internet, thereby enabling the owner of one or more machine units 30 to perform the following operations: remotely update the software and settings of one or more machine units 30, and / or control the operation and functions of one or more machine units via the web-centric and / or mobile application software application, platform and database hosted and operated on the central computer server 32, and / or remotely activate and deactivate one or more machine units 30, and / or instantly remotely range real-time or historical statistical information regarding repairs performed by such machine units 30, repairs performed by each technician, repairs performed by each time period, repairs performed by each location, repairs per grouped mobile electronic device model, technician, time period and location, repair / refurbishment success rate, repair time, mobile electronic device model repaired, technician identity, machine defects, incorrect machine settings, user-identified machine defaults, consumables and parts, and the ability to immediately order such items via the web-centric and / or mobile application software application.

[0069] Now go to Figure 1B , and also shows that Figure 1A and Figure 1C and Figure 1DThe control printed circuit board 33 shown. The control printed circuit board 33 has a processor with operating system software and has many features and functions. The control PCB 33 is used to operate and control various components of the machine unit 30 and a series of operations of the components, namely the actuator 6, vacuum pump 1, solenoid valve 5, operating button 7, LCD / OLED screen display 8, capping sensor 27, communication printed circuit board 34 (with processor and operating system software, not shown) and closing safety switch 14. The control PCB 33 is also used to supply the correct amount of power (voltage and current) to the above components. The control printed circuit board 33 also performs Internet two-way data and command communication to the central computer server 32 hosting and operating network-centric and / or mobile application software applications, platforms and databases via the communication printed circuit board 34, thereby allowing users of network-centric and / or mobile application software applications hosted on the central computer server 32 to remotely operate the machine unit 30 via the Internet and / or remotely update the software and settings of the machine unit 30 via the Internet, and also obtain real-time data on the performance, function, settings, operation, defects and use of the machine unit 30. More specifically (but not limitingly), the web-centric and / or mobile application software application hosted on the central computer server 32 is used to enable and facilitate the following operations: remote control of the machine unit 30 via the Internet and / or remote updating of the software and settings of the machine unit 30 via the Internet, real-time remote transmission and reception of instructions, operating procedures, lamination and defoaming parameters (pressure, timing, repair steps) and data specific to a specific mobile device model to and from the machine unit 30 and the central server 32 via the Internet during the repair process, and also for providing real-time and historical machine operation and repair / refurbishment related data to system users. The control printed circuit board 33 also provides the owner of one or more machine units 30 with the ability to remotely update the software and settings of one or more machine units 30 and / or remotely control the operation of one or more machine units 30 and / or remotely activate and deactivate one or more machine units 30 and / or instantly remotely access real-time or historical statistics regarding repairs performed by such machine units 30, repairs per mobile electronic device model, repairs performed by each technician, repairs performed per time period, repairs performed per location, repairs per grouped mobile electronic device model, technicians, time periods and locations, repair success rates, repair times, mobile electronic device models repaired, technician identities, machine unit 30 defects, erroneous machine unit 30 settings, machine unit 30 defaults identified by the user, needed consumables and parts, and the ability to instantly order such consumables and parts via a web-centric and / or mobile application software application. Those skilled in the art will recognize that the control printed circuit board 33 can be installed in various locations within the machine unit 30.

[0070] Now go to Figure 1C and Figure 1D , a Wi-Fi antenna 35 with a WPS button 39, an on / off power switch 36, an Ethernet inlet port 37, a USB inlet port 41, a power inlet port 38, and an air inlet port 40 are shown. The Wi-Fi antenna 35 with the WPS button 39 is used to connect the communication printed circuit board 34 to a wireless Internet network, the on / off power switch 36 is used to power on and off the machine unit 30, the Ethernet inlet port 37 is used to connect the communication printed circuit board 34 to a wired Internet network, the USB inlet port 41 is used to provide access to the operating software system of the control printed circuit board 33 from an external computer and is also used to update the software on the control printed circuit board 33, the power inlet port 38 is used to connect power to the control printed circuit board 33, and the air inlet port 40 is used to deliver and distribute high-pressure air from the external air compressor 31 to the central air distribution block 4. Those skilled in the art will recognize that in the case where the vacuum pump 1 is located outside the machine unit 30, a second air inlet port (not shown) should be used to connect the machine unit 30 to the external vacuum pump. The machine cooling fan 17 is also shown in the assembled position and can be considered to be facing the vacuum pump 1 so that the machine cooling fan 17 blows directly to the vacuum pump 1 to achieve maximum cooling results. Those skilled in the art will recognize that if the vacuum pump 1 is located outside the machine unit 30, the machine cooling fan 17 is not required but optional. Although Wi-Fi, WPS, Ethernet, USB, etc. are described herein, other types of communication technologies are also contemplated and considered to be within the scope of the present technology.

[0071] Now go to Figure 1E and Figure 1F , the top side view and top front view of the machine unit 30 provide all the internal components assembled and in place (wiring and piping not shown). Two chamber magnets 42 are shown at the base of the internal components of the metal vacuum pressure chamber 24. These chamber magnets 42 are used to properly align the lamination mold 49 when it is placed into the metal vacuum pressure chamber 24. Figure 1E It also shows how the actuator 6 passes through a hole in the metal vacuum pressure chamber to connect to the metal cover 15, and Figure 1F The metal cover 15 is shown in a closed lowered position when the metal vacuum pressure chamber 24 is sealed.

[0072] Now go to Figure 1G to Figure 1L , showing external views of the machine unit 30 at different angles, with the metal cover 15 in a raised position when the metal vacuum pressure chamber 24 is open and the metal cover 15 in a lowered position when the metal vacuum pressure chamber 24 is closed and sealed. Those skilled in the art will recognize that the machine unit 30 as disclosed herein is not limited to Figures 1A to 1L Design shown.

[0073] Now go to Figure 2A , showing that Figures 1A to 1H The four actuators 6 shown are securely attached and screwed to the bottom housing base 3 in order to handle a holding force of over 1500 Newtons per actuator.

[0074] Now go to Figures 2B to 2G , shows a central air distribution block 4 with solenoid valves 5 and an air pressure sensor 43, a central air distribution block fan 44, a vacuum pump 1, a piston chamber 21, a metal vacuum pressure chamber 24, and an air line. The central air distribution block 4 distributes air into and out of the above-mentioned components that provide assistance for the functions of the machine unit 30. One of the solenoid valves 5 is connected to an external air compressor 31 via an air line to introduce high-pressure air into the central air distribution chamber 4, and then distributes the high-pressure air from the central air distribution chamber 4 to the various components of the machine unit 30 mentioned above and below. Another solenoid valve 5 is connected to an air input and output port 45 of the metal vacuum pressure chamber 24 via an air line, and this is a way to distribute air into and out of the central air distribution chamber 4 and the metal vacuum pressure chamber 24. Another solenoid valve 5 is connected to the airbag chamber air port 47 to distribute air into and out of the central air distribution chamber 4 and the airbags. Another solenoid valve 5 is connected to the air input outlet port 48 at the bottom part of the piston chamber 21 via an air line, and when air is released from the central air distribution chamber 4 to the bottom part of the piston chamber 21, this will push the piston (not shown) and the piston plate 10 upward. Another solenoid valve 5 is connected to the vacuum pump 1 via an air line for the vacuum pump 1 to draw air from the metal vacuum pressure chamber 24 so as to create a vacuum. Those skilled in the art will recognize that if the vacuum pump 1 is located outside the machine unit 30, the above-mentioned solenoid valve 5 will be connected to the external vacuum pump via the second air inlet port mentioned above. Another solenoid valve 5 is connected to the top part of the piston chamber 21 via an air port 46 located on the lower side of the metal vacuum pressure chamber 24 to distribute air from the central air distribution block 4 and push the air into the top part of the piston chamber so as to push the piston and the piston plate 10 downward. Those skilled in the art will recognize that the passage of air may vary depending on the design and type of the piston and piston chamber 21 used and the air passage design of the central air distribution block 4 and / or the metal vacuum pressure chamber 24. Central air distribution block fans 44 are used to cool central air distribution block 4 as well as solenoid valve 5. Those skilled in the art will recognize that the number, size, and performance of central air distribution block fans 44 may vary depending on system performance requirements.

[0075] Go to again Figures 2B to 2G and Figures 1A to 1L, various basic functions of the machine unit 30, such as lamination and defoaming functions, can be explained. The lamination process involves the following process. The actuator 6 is activated and lifts the metal cover 15 so as to open the metal vacuum pressure chamber 24. The item to be laminated is then placed in the inner part of the metal vacuum pressure chamber 24, and the actuator 6 then drives the metal cover 15 downward until the metal vacuum pressure chamber 24 is closed and sealed. The vacuum pump 1 is turned on, after which the solenoid valve 5 connected to the vacuum pump 1 is opened and the solenoid valve 5 connected to the air input and output port 45 of the metal vacuum pressure chamber 24 is also opened, allowing the vacuum pump 1 to suck all the air out of the metal vacuum pressure chamber 24 until the air pressure sensor 43 detects that vacuum has been reached. Afterwards, the solenoid valve 5 connected to the vacuum pump 1 is closed and the solenoid valve 5 connected to the air input and output port 45 of the metal vacuum pressure chamber 24 is also closed. Afterwards, the solenoid valve 5 port connected to the external air compressor 31 allows high-pressure air to flow into the central air distribution block 4, and the solenoid valve 5 connected to the air input outlet port 48 located at the bottom portion of the piston chamber 21 is opened, causing high-pressure air to flow from the central distribution block 4 to the bottom portion of the piston chamber 21, thereby pushing the piston (not shown) and the piston plate 10 upward into the metal vacuum pressure chamber 24 and applying upward pressure to the items placed in the metal vacuum pressure chamber 24. If downward lamination pressure is used, the solenoid valve 5 connected to the airbag air port 47 is opened so that high-pressure air can flow from the central air distribution block 4 to the airbag 13, thereby inflating the airbag in the metal vacuum pressure chamber 24 and applying downward pressure to the items placed in the metal vacuum pressure chamber 24. Afterwards, the solenoid valve 5 connected to the bottom portion of the piston chamber 21 is closed, and then the solenoid valve 5 connected to the top portion of the piston chamber 21 is opened, allowing high-pressure air to flow from the central air distribution block 4 and enter the top portion of the piston chamber 21, thereby pushing the piston (not shown) and the piston plate 10 downward. Afterwards, the solenoid valve 5 connected to the top portion of the piston chamber 21 is closed, the solenoid valve 5 connected to the external air compressor 31 is closed, and the actuator 6 is activated and lifts the metal cover 15, thereby opening the metal vacuum pressure chamber 24. All of the above processes are controlled by software in the processor controlling the printed circuit board 33. Those skilled in the art will recognize that the sequence, process, air channel, air speed, piston speed, air pressure level and other settings may vary depending on the atmospheric pressure and the type of mobile electronic device screen being laminated.

[0076] The defoaming process involves the following process. The actuator 6 is activated and lifts the metal cover 15 so as to open the metal vacuum pressure chamber 24. The item to be defoamed is then placed in the interior portion of the metal vacuum pressure chamber 24, and the actuator 6 then drives the metal cover 15 downward until the metal vacuum pressure chamber 24 is closed and sealed. Afterwards, the solenoid valve 5 connected to the external air compressor 31 opens, allowing high-pressure air to flow into the central air distribution block 4, and the solenoid valve 5 connected to the air input and output port 45 of the metal vacuum pressure chamber 24 opens, causing high-pressure air to flow from the central distribution block 4 and enter the metal vacuum pressure chamber 24, thereby applying a high level of air pressure to the item to be defoamed that has been placed in the metal vacuum pressure chamber 24. The air pressure sensor 43 reads the pressure in the metal vacuum pressure chamber 24, and based on these readings, more air is added until the correct air pressure is reached in the metal vacuum pressure chamber 24. Once the debubbling period has expired, the solenoid valve 5 connected to the external air compressor 31 is closed, the solenoid valve 5 of the central air distribution block 4 that exhausts air to the atmosphere is opened, allowing the air in the metal vacuum pressure chamber 24 to be exhausted, and then the actuator 6 is activated and lifts the metal cover 15, thereby opening the metal vacuum pressure chamber 24. This process is controlled by software in the processor of the control printed circuit board 33. Those skilled in the art will recognize that the sequence, process, air passage, air speed, air pressure level and other settings may vary depending on the atmospheric pressure and the type of mobile electronic device screen being debubbled.

[0077] Now go to Figure 2H ,like Figures 1A to 1E The metal vacuum pressure chamber 24 and the piston chamber 21 shown are shown separately, specifically showing the four holes through which the four actuators pass, the chamber magnet 42 for aligning the lamination mold 49, the capping sensor 27, the airbag air input and output ports, and how the piston chamber 21 is attached to the underside of the metal vacuum pressure chamber 24.

[0078] Now go to Fig.2I , on the lower side of the metal cover 15, the safety switch bracket 12 is attached to the lower side of the metal cover 15, and the airbag bracket 28, the airbag 13 and the airbag air inlet and outlet ports are shown separately, and the installation and placement on the lower side of the metal cover 15 are illustrated.

[0079] Now go to Figures 3A to 3G, various views of the lamination mold 49 and related components are shown. A metal lamination mold base 50 is shown. The metal lamination mold base 50 serves as a base on which all the lamination mold components are placed. Two lamination mold magnets 55 are also shown. The lamination mold magnets are used to align the lamination mold 49 with the chamber magnets 42 to ensure that the lamination mold 49 is perfectly aligned within the metal vacuum pressure chamber 24. A lamination mold suspension frame 51 is also shown. The lamination mold suspension frame has a top metal layer and a lower foam layer glued to the metal lamination mold base 50 so that when the top end of the lamination mold suspension frame 51 is pressed down, there is a spring rebound effect. An LCD / OLED cutout insert 52 is also shown. The LCD / OLED cutout insert 52 serves as a base on which the LCD / OLED screen 53 is placed, and the inversion of the LCD / OLED cutout insert 52 is an exact negative image of the rear end of the LCD / OLED screen 53, so that the LCD / OLED screen 53 is completely flush when the LCD / OLED screen 53 is placed on the LCD / OLED cutout insert 52. The lamination mold hanging frame 51 also serves as a holder or base for the top and bottom ends of the outer glass layer 54 with adhesive 56, so that the outer glass layer 54 with adhesive 56 does not contact the LCD / OLED screen below before the lamination mold hanging frame 51 is pushed down during the lamination process.

[0080] Now go to Figure 3F and Figure 3G , clearly showing how the outer glass layer 54 with adhesive 56 and the LCD / OLED screen 53 are prior to lamination ( Figure 3F ) and during lamination ( Figure 3G ) for positioning. Figure 3F It shows how the outer glass layer 54 with adhesive 56 rests on top of the lamination mold suspension frame 51 and does not contact the LCD / OLED screen 53 below. Figure 3G It shows how the piston and piston plate 10 push the laminating die 49 upward against the metal cover 15, causing the laminating die suspension frame 51 to be pushed downward, thereby causing the outer glass layer 54 with adhesive 56 to be pushed downward onto the LCD / OLED screen 53 below, causing the outer glass layer 54 and LCD / OLED screen 53 to be laminated together.
