Abstract
Description
Technical Field
[0001] This invention relates to the field of smart fitness mirror manufacturing, specifically a manufacturing method for smart fitness mirrors based on a full-fitting process. Background Technology
[0002] A smart fitness mirror is a full-length mirror used by users in their private areas for fitness training. The emergence of smart fitness mirrors greatly benefits users' time management, allowing them to save time at the gym. Unlike using simple electronic devices for exercise training, smart fitness mirrors can effectively observe users' posture and make timely adjustments based on the mirror's instructions, thus preventing injuries caused by incorrect posture.
[0003] Currently, the main problem encountered when using smart fitness mirrors is their poor display quality. This is because existing technologies for manufacturing smart fitness mirrors primarily employ frame-mount technology, mainly using an integrated LCD module and backlight module. Foam is used to seal the edges between the mirror glass and the LCD module. This creates an air gap between the mirror glass and the LCD module. Due to the influence of this air gap, the smart fitness mirror will produce ghosting and significantly affect the viewing angle, which seriously impacts the user experience. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of existing smart fitness mirrors, which suffer from ghosting due to air gaps between the mirror glass and the liquid crystal module. This invention provides a manufacturing method for a smart fitness mirror based on a full lamination process, which eliminates air gaps and thus eliminates ghosting by fully laminating the mirror glass and the liquid crystal module.
[0005] The objective of this invention is mainly achieved through the following technical solutions:
[0006] The manufacturing method of a smart fitness mirror based on full-fit technology includes the following steps:
[0007] The system includes a liquid crystal module and a backlight module, which are independent of each other.
[0008] A mirrored glass is installed, and the bonding surface between the mirrored glass and the liquid crystal module is completely covered with adhesive. The liquid crystal module is then bonded to the mirrored glass.
[0009] The liquid crystal module and the mirror glass are pressed together to make the adhesive fill the space between the liquid crystal module and the mirror glass evenly.
[0010] A frame is provided, and the backlight module is fixed on the frame;
[0011] The liquid crystal module and the backlight module are bonded together.
[0012] Currently, in the production of smart fitness mirrors, frame bonding technology is commonly used to bond the mirror glass and the display module. This bonding method not only produces ghosting but also affects the viewing range of the smart fitness mirror, seriously impacting the user experience. There are two main reasons for using this bonding method: First, to control production costs, as the components and materials required for frame bonding are relatively inexpensive and the process is simpler; second, the display module is an integrated unit, with the backlight module and the LCD module combined into one piece, making it inconvenient to bond the LCD module to the mirror glass.
[0013] In this invention, the liquid crystal module and the backlight module are separated into two independent parts. By fully bonding the liquid crystal module and the mirror glass with adhesive, the ghosting problem of the smart fitness mirror is eliminated. Since the liquid crystal module and the backlight module are independent, the difficulty of bonding the mirror glass and the display module is greatly reduced, thereby improving the product yield and reducing labor costs. In addition to eliminating ghosting by eliminating air gaps, this invention also improves economic efficiency.
[0014] Furthermore, the specific bonding process between the liquid crystal module and the mirror surface is as follows:
[0015] The mirror glass and the liquid crystal module are heated at a constant temperature. After heating, the mirror glass and the liquid crystal module are bonded together. The bonded mirror glass and liquid crystal module are then hot-pressed, and adhesive is injected into the bonding surface between the liquid crystal module and the mirror glass. When using a full lamination process, the biggest impact on the manufacturer is the low yield rate. One reason for the low yield rate is the limited operation time for full lamination. Therefore, the error tolerance rate is often low during full lamination, resulting in a lower yield rate. Since the adhesive used in full lamination is water-based or optical adhesive, the curing time of the adhesive increases with increasing temperature. To protect the liquid crystal module, the hot-pressing temperature used in this invention is controlled within a range that does not damage the liquid crystal module. By increasing the temperature, the curing time of the adhesive is increased, providing more adjustment time for the bonding between the mirror glass and the liquid crystal module, thus improving the error tolerance rate of the bonding process.
[0016] Furthermore, the hot pressing includes the following steps:
[0017] The liquid crystal module and the mirror glass are placed in a constant temperature chamber for a period of time until the temperature of the liquid crystal module and the mirror glass is constant.
[0018] In a constant temperature chamber, a pressure plate with an area larger than that of the liquid crystal module and the mirror glass is used to flatten the liquid crystal module and the mirror glass until the colloid between the mirror glass and the liquid crystal module is evenly distributed.
[0019] Remove the liquid crystal module and mirror glass from the constant temperature chamber and continue to apply pressure until the liquid crystal module and mirror glass return to room temperature.
[0020] In this invention, by controlling the constant temperature of the liquid crystal module and the mirror glass, the stress state of the liquid crystal module, the mirror glass, and the intermediate colloid is effectively improved, avoiding excessive local thickness of the colloid due to uneven local coating. Through flat pressing, the unevenly distributed colloid is effectively spread evenly by extrusion during the time before the colloid solidifies. Although the optical adhesive and water-based adhesive used for full lamination do not change much in volume under the influence of temperature, in order to ensure that the liquid crystal module and the mirror glass do not deform under the influence of the colloid, this invention continuously applies flat pressing to the liquid crystal module and the mirror glass at room temperature, thereby obtaining a flatter combination of liquid crystal module and mirror glass. The pressing sheet area used in this invention is larger than that of the liquid crystal module and the mirror glass, which can apply pressure to the liquid crystal module and the mirror glass evenly and effectively.
[0021] Furthermore, when flattening the liquid crystal module and the mirror glass at room temperature, rolling and pressing are performed on the pressing plate. This rolling and pressing is continuous, moving from one side of the pressing plate to the opposite side, and this operation is repeated at least once on each side of the pressing plate. Due to the constant temperature heating and cooling process, stress accumulates in the assembly of the liquid crystal module and the mirror glass. Over prolonged use, the release of this stress can lead to physical damage to the mirror glass and the liquid crystal module. This invention uses rolling and pressing in conjunction with room temperature placement to release stress in the assembly of the liquid crystal module and the mirror glass. Furthermore, rolling and pressing effectively flattens the assembly of the liquid crystal module and the mirror glass through external force. The pressure of the rolling and pressing is effectively controlled in this invention, ensuring that no physical damage is caused to the assembly of the liquid crystal module and the mirror glass.
[0022] Furthermore, the pressing sheet is repeatedly rolled and pressed at least three times, with the rolling pressure during the intermediate rolls being greater than the initial rolling pressure and the final rolling pressure. This invention avoids poor rolling results or stress concentration after rolling by using at least three rolling processes. By using at least three rolling processes, a flat and well-fitted liquid crystal module and mirror glass assembly can be effectively obtained.
[0023] Furthermore, when the liquid crystal module and the mirror glass are located inside the constant temperature chamber, the liquid crystal module and the mirror glass are kept in a flat pressure state, and the temperature inside the constant temperature chamber is adjusted at least three times. After each temperature adjustment, the temperature of the liquid crystal module and the mirror glass is allowed to reach equilibrium. This invention employs a stepped cooling method to adjust the assembly of the liquid crystal module and the mirror glass to room temperature, avoiding the rapid shrinkage of the colloid, mirror glass, and / or liquid crystal module caused by abrupt temperature differences, thereby preventing physical damage such as cracks and shrinkage due to rapid temperature changes.
[0024] Furthermore, a liquid bag is placed on the tablet, the temperature of the liquid bag is kept consistent with that inside the constant temperature chamber, and the shape and size of the liquid bag are the same as those of the tablet.
[0025] When flattening mirror glass and liquid crystal module, it is extremely important to maintain uniform pressure on the object. Since the liquid crystal module itself is relatively fragile, uneven force during the bonding stage will greatly affect the adhesion between the liquid crystal module and the mirror glass. Therefore, in order to ensure the uniformity of pressure when applying pressure to the pressing sheet, this invention utilizes the uniformity of liquid pressure by placing a liquid bag on the pressing sheet with the same temperature as the constant temperature chamber. The liquid bag applies pressure to the pressing sheet, and the shape and size of the liquid bag are the same as the pressing sheet, ensuring the uniformity of pressure applied to the pressing sheet as a whole.
[0026] Furthermore, the liquid bag includes a bag body, and an inlet pipe and a drain pipe are provided on the top of the bag body;
[0027] The water inlet pipe is inserted into the bag body and the end of the water inlet pipe contacts the bottom of the bag body;
[0028] The water suction pipe is inserted into the bag body and the end of the water suction pipe contacts the bottom of the bag body.
[0029] In this invention, an inlet pipe and a drain pipe are used to adjust the amount of liquid in the liquid bag, thereby adjusting the tableting pressure. The end of the inlet pipe contacts the bottom of the bag body, and the end of the drain pipe also contacts the bottom of the bag body, ensuring stable liquid flow in and out of the liquid bag and minimizing excessive local pressure changes. Since the inlet and drain pipes are not connected to the bottom of the liquid bag, they do not affect the pressure exerted by the liquid bag on the tablet. Furthermore, to ensure no local pressure changes, some liquid can be left in the inlet and drain pipes, keeping their liquid levels consistent with the liquid level in the liquid bag.
[0030] Furthermore, the inner wall of the bag is provided with a side telescopic support plate. The upper end of the side telescopic support plate is fixed to the top of the bag, and its lower end is fixed to the bottom of the bag. The enclosed area of the side telescopic support plate within the bag is larger than the area of the pressure plate. In order to limit the pressure of the liquid bag within an effective area, this invention defines the pressure range of the pressure plate by setting a side telescopic support plate. Since the side telescopic support plate can extend and retract, it can effectively adapt to the expansion and contraction of the liquid bag, thereby providing more pressure to the pressure plate within the defined area.
[0031] Furthermore, during the hot pressing of the liquid crystal module and the mirror glass, adhesive is applied to the sides of the liquid crystal module and the mirror glass. In this invention, the volume of the adhesive changes after application. Therefore, by applying adhesive to the sides of the liquid crystal module and the mirror glass, adhesive is added to the bonding surface. If gaps exist, the adhesive penetrates the bonding surface; if no gaps exist, the adhesive can reinforce the position of the liquid crystal module and the mirror glass on their sides.
[0032] In summary, the present invention has the following advantages compared with the prior art:
[0033] (1) In this invention, the liquid crystal module and the backlight module are separated into two independent parts. By fully bonding the liquid crystal module and the mirror glass with adhesive, the ghosting problem of the smart fitness mirror is eliminated. Since the liquid crystal module and the backlight module are independent of each other, the difficulty of bonding the mirror glass and the display module is greatly reduced, thereby improving the product yield and reducing labor costs. In addition to eliminating the ghosting by eliminating the air gap, the economic benefits of this invention are also improved.
[0034] (2) By increasing the temperature, the solidification time of the colloid is increased, providing more adjustment time for the bonding between the mirror glass and the liquid crystal module, thereby improving the tolerance of the bonding between the mirror glass and the liquid crystal module.
[0035] (3) The present invention defines the pressure range of the tablet by setting a side telescopic support plate, and the side telescopic support plate can extend and retract, so it can also effectively adapt to the expansion and contraction of the liquid bag, thereby providing more pressure to the tablet within the limited area.

[0042] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.
[0043] Example:
[0044] like Figures 2-3 As shown, the smart fitness mirror in this embodiment includes a mirror glass 1, a display module 2 and a frame 3. The display module 2 is located between the mirror glass 1 and the frame 3. The display module 2 is divided into two independent parts: a liquid crystal module 21 and a backlight module 22.
[0045] like Figure 1 As shown, this embodiment relates to a manufacturing method for a smart fitness mirror based on a full-fitting process, including the following steps:
[0046] The system includes a liquid crystal module and a backlight module, which are independent of each other.
[0047] A mirrored glass is installed, and the bonding surface between the mirrored glass and the liquid crystal module is completely covered with adhesive. The liquid crystal module is then bonded to the mirrored glass.
[0048] The specific bonding process between the liquid crystal module and the mirror surface is as follows:
[0049] The mirror glass and the liquid crystal module are heated at a constant temperature. The heated mirror glass and the liquid crystal module are then bonded together. The bonded mirror glass and the liquid crystal module are then hot-pressed together, and adhesive is injected into the bonding surface between the liquid crystal module and the mirror glass.
[0050] The liquid crystal module and the mirror glass are pressed together to make the adhesive fill the space between the liquid crystal module and the mirror glass evenly.
[0051] A frame is provided, and the backlight module is fixed on the frame;
[0052] The liquid crystal module and the backlight module are bonded together.
[0053] In this embodiment, the liquid crystal module and the backlight module are separated into two independent parts in practical application. By fully bonding the liquid crystal module and the mirror glass with adhesive, the ghosting problem of the smart fitness mirror is eliminated. Since the liquid crystal module and the backlight module are independent of each other, the difficulty of bonding the mirror glass and the display module is greatly reduced, thereby improving the product yield and reducing labor costs. In addition to eliminating the ghosting by eliminating the air gap, the economic benefits of this invention are also improved.
[0054] The hot pressing includes the following steps:
[0055] The liquid crystal module and the mirror glass are placed in a constant temperature chamber for a period of time until the temperature of the liquid crystal module and the mirror glass is constant.
[0056] Apply adhesive to the sides of the LCD module and the mirror glass.
[0057] In a constant temperature chamber, a pressure plate with an area larger than that of the liquid crystal module and the mirror glass is used to flatten the liquid crystal module and the mirror glass until the colloid between the mirror glass and the liquid crystal module is evenly distributed.
[0058] Maintain the LCD module and the mirror glass under flat pressure and adjust the temperature inside the constant temperature chamber at least three times. After each temperature adjustment, wait for the temperature of the LCD module and the mirror glass to reach equilibrium.
[0059] In this embodiment, by controlling the constant temperature of the liquid crystal module and the mirror glass, the stress state of the liquid crystal module, the mirror glass and the intermediate colloid is effectively improved, avoiding excessive local thickness of the colloid due to uneven local coating. By using the flat pressing operation, the unevenly distributed colloid is effectively spread evenly by extrusion during the time before the colloid solidifies. Although the optical adhesive and water adhesive used for full lamination do not change much in volume under the influence of temperature, in order to ensure that the liquid crystal module and the mirror glass will not deform under the influence of the colloid, this invention continuously applies flat pressing to the liquid crystal module and the mirror glass at room temperature, thereby obtaining a flatter combination of liquid crystal module and mirror glass.
[0060] In this embodiment, the temperature is controlled within a range that does not affect the normal use of the liquid crystal module, and the pressure applied to the liquid crystal module is also controlled within its tolerable range.
[0061] This embodiment involves temperature control of electronic components, which effectively improves their adaptability to long-term operation. Furthermore, this temperature control process can effectively eliminate some liquid crystal modules that are not suitable for long-term operation, thereby obtaining a smart fitness mirror that can maintain long-term operation and adapt to its own heat, thus avoiding damage to the smart fitness mirror due to insufficient heat dissipation during long-term operation.
[0062] Remove the liquid crystal module and mirror glass from the constant temperature chamber and continue flat pressing until they return to room temperature. While flat pressing the liquid crystal module and mirror glass at room temperature, roll and press them continuously from one side of the pressing sheet to the opposite side, repeating this operation at least once from each side of the pressing sheet.
[0063] The tablet is repeatedly rolled and compacted at least three times, with the rolling and compacting pressure in the middle of the rolls being greater than the initial rolling and compacting pressure and the final rolling and compacting pressure.
[0064] In this embodiment, a stepped cooling method is used to adjust the combination of the liquid crystal module and the mirror glass to room temperature, avoiding the rapid shrinkage of the colloid, mirror glass, and / or liquid crystal module caused by sudden temperature differences, thereby avoiding physical damage such as cracks and shrinkage caused by rapid temperature changes. Rolling and pressing are used to improve the overall physical properties of the display module 2 and obtain a flatter display module 2.
[0065] In this embodiment, the adhesive used is OCA adhesive, which is a special adhesive used to bond transparent optical components. It is colorless and transparent, has a light transmittance of over 90%, good bonding strength, can be cured at room temperature or medium temperature, and has low curing shrinkage.
[0066] In one specific embodiment of this example, a liquid bag 4 is placed on the tablet, the temperature of the liquid bag 4 is consistent with that inside the constant temperature chamber, and the shape and size of the liquid bag 4 are the same as those of the tablet.
[0067] The liquid bag 4 includes a bag body 41, and an inlet pipe 43 and a drain pipe 44 are provided above the bag body 41.
[0068] The water inlet pipe 43 is inserted into the bag body 41 and the end of the water inlet pipe 43 contacts the bottom of the bag body 41.
[0069] The drain pipe 44 is inserted into the bag body 41 and the end of the drain pipe 44 contacts the bottom of the bag body 41.
[0070] The inner wall of the bag body 41 is provided with a side telescopic support plate 42. The upper end of the side telescopic support plate 42 is fixed to the top of the bag body 41, and its lower end is fixed to the bottom of the bag body 41. The enclosed area of the side telescopic support plate 42 inside the bag body 41 is larger than the area of the pressure plate.
[0071] In this embodiment, it is extremely important to maintain uniform pressure on the object being pressed when flattening the mirror glass 1 and the liquid crystal module 21. Since the liquid crystal module 21 is relatively fragile, uneven force during the bonding stage will greatly affect the adhesion between the liquid crystal module 21 and the mirror glass 1. Therefore, in order to ensure the uniformity of pressure when applying pressure to the pressing sheet, this embodiment utilizes the uniformity of liquid pressure by placing a liquid bag 4 on the pressing sheet with the same temperature as the constant temperature chamber. Pressure is applied to the pressing sheet through the liquid bag 4, and the shape and size of the liquid bag 4 are the same as the pressing sheet, ensuring the uniformity of pressure applied to the pressing sheet as a whole.
[0072] In order to limit the pressure of the liquid bag 4 within the effective area, this embodiment defines the pressure range of the tablet by setting a side telescopic support plate 42. The side telescopic support plate 42 can extend and retract, so it can also effectively adapt to the expansion and contraction of the liquid bag 4, thereby providing more pressure to the tablet within the limited area.
[0073] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
