Description

Technical Field

[0001] The present invention belongs to the technical field of electronic device disassembly, and in particular relates to a screen disassembly device. Background Art

[0002] During the production of electronic devices with screens, if the front frame of a screen is damaged or the screen itself is damaged and needs to be replaced, the screen and front frame must be separated. Because the screen and front frame are bonded together, separating them requires heating them in a high-temperature oven for a period of time to reduce the adhesive on the backing. After removing the screen from the oven, a card tool can be inserted into the gap to separate the screen from the front frame.

[0003] The aforementioned screen disassembly method can easily damage the screen or front frame and is highly dependent on skilled labor. To this end, patent CN212947532U provides a screen disassembly device and system, including a sealing seat, a pneumatic device, and a heating device. The sealing seat has a cavity, an opening connected to the cavity, and an air inlet connected to the cavity; the pneumatic device includes an air source device and an air inlet pipeline, one end of the air inlet pipeline is connected to the air source device, and the other end of the air inlet pipeline is connected to the air inlet. The air source device delivers gas to the cavity through the air inlet pipeline, and the heating device heats the sealant, so that the air pressure generated by the sealed gas pushes the screen out of the frame, realizing the separation of the screen and the frame.

[0004] However, most existing screen disassembly devices similar to the above-mentioned patent use air pressure as the power for disassembly, and the starting device has a complex structure, resulting in high airtightness requirements and high maintenance technology requirements. Summary of the Invention

[0005] In response to the shortcomings in the related art, the present invention provides a screen disassembly device, which realizes the separation of the screen and the front frame through a mechanical structure, so as to solve the technical problems of high airtightness requirements and high maintenance technology requirements in the existing device.

[0006] The present invention provides a screen disassembly device for separating a screen and a front frame connected by adhesive, comprising:

[0007] Box;

[0008] A potential energy driving component is mounted on the box;

[0009] The pressing component is installed on the box body. When the pressing component presses the front frame toward the potential energy driving component, the screen pushes the potential energy driving component to generate elastic potential energy;

[0010] The heating component is installed on the box. When the heating component heats the adhesive, the potential energy driving component pushes the screen out of the front frame through elastic potential energy.

[0011] This technical solution uses the elastic potential energy generated by the mechanical structure to separate the screen from the front frame after the back glue is heated. It has a simple structure and is easy to operate.

[0012] In some embodiments, the potential energy driving component includes:

[0013] The elastic element is mounted on the bottom plate of the box;

[0014] The driving plate is mounted on the elastic element. When the pressing assembly presses the front frame, the driving plate is attached to the screen and is pushed toward the elastic element by the screen, so that the elastic element generates elastic potential energy.

[0015] This technical solution realizes elastic energy storage and provides thrust for the detachment of the screen through elastic elements, and has a simple structure.

[0016] In some embodiments, the holding assembly includes:

[0017] A first connecting rod is mounted on the side panel or top panel of the box;

[0018] The pressing member is mounted on the first connecting rod and presses the front frame.

[0019] This technical solution realizes the limited pressing of the front frame through the pressing member, and enables the potential energy driving component to generate elastic potential energy.

[0020] In some embodiments, the heating assembly comprises:

[0021] A second connecting rod is mounted on the top plate of the box body;

[0022] The heating plate is installed on the second connecting rod. When the heating plate is attached to the screen, the back glue is heated.

[0023] This technical solution achieves heating of the adhesive backing by covering the screen with a heating plate.

[0024] In some embodiments, the elastic element is a compression spring or a gas spring. This technical solution enables the elastic element to generate elastic potential energy under compression.

[0025] In some embodiments, there are two sets of pressing components, which are respectively installed on both sides of the box body. This technical solution uses two sets of pressing components to press both sides of the front frame respectively, thereby improving the stability of the pressed lower front frame.

[0026] In some embodiments, a first connecting rod is rotatably connected to the holding member and threadedly engaged in a mounting hole provided in the housing. When the first connecting rod rotates, it moves axially on the housing, driving axial movement of the holding member. This technical solution adjusts the spacing between the holding members of the two holding assemblies by rotating the first connecting rod, thereby enabling the holding of front frames of varying sizes.

[0027] In some embodiments, the holding members are holding plates, and the holding plates in both sets of holding assemblies are arranged vertically and parallel to each other. This technical solution uses the two holding plates to guide the two sides of the dislodged screen and the two sides of the heating plate, preventing the screen from sliding and breaking after being dislodged from the front frame, and preventing the heating plate from deflecting and getting stuck during movement.

[0028] In some embodiments, the second connecting rod is a telescopic rod. This technical solution enables the movement of the heating plate to prevent the heating plate from hindering the screen from being dislodged.

[0029] In some embodiments, the housing has an operating cavity and an operating port communicating with the operating cavity, wherein the potential energy drive assembly, the holding assembly, and the heating assembly are all located in the operating cavity. This technical solution utilizes the operating port to facilitate the insertion of the device to be disassembled and the removal of the screen and front frame after disassembly.

[0030] Based on the above technical solution, in the embodiment of the present invention, the pressure-holding component presses the front frame, so that the potential energy driving component generates elastic potential energy, and then under the heating of the back glue by the heating component, the potential energy driving component overcomes the adhesive force of the back glue and pushes the screen out of the front frame. The separation of the screen and the front frame is achieved through a mechanical structure. The overall structure is simple, the precision requirement is low, the operation is convenient, the requirements for operators are low, and it is convenient for production, manufacturing and maintenance, which solves the technical problems of high airtightness requirements and high maintenance technology requirements in existing devices.

[0041] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0042] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0043] The terms "first," "second," and "third" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly specify the quantity of the technical features indicated. Thus, a feature specified as "first," "second," or "third" may explicitly or implicitly include one or more of such features.

[0044] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0045] like Figures 1 to 3 As shown, in an exemplary embodiment of the screen disassembly device of the present invention, the screen disassembly device includes a box body 1, a potential energy driving component 2, a pressing component 3 and a heating component 4, and the potential energy driving component 2, the pressing component 3 and the heating component 4 are all installed on the box body 1.

[0046] Screen A and front frame B, connected by adhesive, are placed entirely within housing 1. Pressing assembly 3 presses front frame B against potential drive assembly 2, generating elastic potential energy. Heating assembly 4 heats the adhesive, reducing its viscosity. The elastic potential energy of potential drive assembly 2 acts on screen A, overcoming the adhesive force and pushing screen A out of the front frame, separating them.

[0047] In the above-mentioned schematic embodiment, the holding component 3 presses the front frame B, so that the potential energy driving component 2 generates elastic potential energy. Then, under the heating of the back glue by the heating component 3, the potential energy driving component 2 overcomes the adhesive force of the back glue and pushes the screen A out of the front frame B, thereby realizing the separation of the screen A and the front frame B through the mechanical structure. The working precision requirements of each component are low, the structure is simple and the operation is easy. Unskilled workers can also complete the separation operation. The efficiency of the disassembly work is high, which solves the technical problems of high airtightness requirements and high maintenance technology requirements in the existing device.

[0048] In some embodiments, the housing 1 has an operating cavity 11 and an operating port 12 communicating with the operating cavity 11. The potential energy drive assembly 2, the holding assembly 3, and the heating assembly 4 are all located in the operating cavity 11. The separation of the screen A and the front frame B is performed within the operating cavity 11. The housing 1 provides protection and prevents the screen A from flying out of the housing 1 and causing collision or falling when detached.

[0049] In some embodiments, the potential energy driving component 2 includes an elastic element 21 and a driving plate 22. The elastic element 21 is mounted on the bottom plate 13 of the housing 1, and the driving plate 22 is mounted on the elastic element 21. When the pressing component 3 presses the front frame B, it pushes the front frame B toward the bottom plate 13, so that the screen A connected to the front frame B pushes the driving plate 22 toward the bottom plate 13. The distance between the driving plate 22 and the bottom plate 13 becomes smaller, and the elastic element 21 is compressed to achieve the generation of elastic potential energy. After the backing adhesive is heated, the adhesive force decreases, and the thrust provided by the elastic potential energy of the elastic element 21 overcomes the adhesive force, thereby pushing the screen A out of the front frame B through the driving plate 22. The area of ​​the driving plate 22 is smaller than the window area of ​​the front frame B, ensuring that the front frame B will not cause obstruction when the driving plate 22 pushes the screen A out.

[0050] In some embodiments, the elastic element 21 is a compression spring or gas spring, which generates elastic potential energy upon compression. Compression springs are commonly used elastic elements and are readily available. To generate sufficient elastic potential energy, multiple compression springs can be provided, evenly distributed front, back, left, and right. This ensures uniform elastic force across the drive plate 22 and provides a certain degree of guidance for the smooth movement of the drive plate 22. Gas springs have a piston rod structure and a relatively fixed movement direction, which can guide the movement of the drive plate 22 and ensure smooth movement of the drive plate 22.

[0051] In some embodiments, the holding assembly 3 includes a first connecting rod 31 and a holding member 32. The first connecting rod 31 is mounted on the side panel 14 of the housing 1, and the holding member 32 is mounted on the first connecting rod 31. The first connecting rod 31 supports the holding member 32, causing it to press against the upper surface of the front frame B, preventing the front frame B from moving upward. This causes the screen A to press downward on the drive plate 22, compressing the elastic element 21 and generating elastic potential energy. The first connecting rod 31 can also be mounted on the top plate 15 of the housing 1, so that the top plate 15 of the housing 1 supports the holding member 32 via the first connecting rod 31, thereby enabling the holding member 32 to press against the front frame B.

[0052] In some embodiments, the heating assembly 4 includes a second connecting rod 41 and a heating plate 42. The second connecting rod 41 is mounted on the top plate 15 of the box body 1, and the heating plate 42 is mounted on the second connecting rod 41. The heating plate 42 can adopt heating devices such as electric heating and heat pipe heating structure, and the present application does not limit the specific structure of the heating plate. When the bottom plate 13 of the box body 1 is installed with the potential energy drive assembly 2, the heating assembly 4 needs to be installed on the top plate 15 of the box body 1 so that the heating plate 42 can contact the screen A surface, thereby heating the adhesive on the back of the screen A and reducing the adhesion of the adhesive.

[0053] In some embodiments, there are two sets of pressing assemblies 3, one mounted on each side of the housing 1. The pressing members 32 of each set of pressing assemblies 3 respectively press one side of the front frame B, thereby maintaining a stable connection between the front frame B and the screen A, thereby fully pushing the potential energy driving assembly 2 and generating elastic potential energy.

[0054] In some embodiments, the first connecting rod 31 is rotatably connected to the holding member 32, meaning that the first connecting rod 31 can rotate on the holding member 32. The first connecting rod 31 is also threaded into the mounting hole 16 provided in the housing 1. Through this threaded engagement, when the first connecting rod 31 rotates, it can move axially on the housing 1, thereby driving the holding member 32 to move axially. When the holding assembly 3 comprises two sets and is mounted on the side panel 13, the spacing between the two holding members 32 can be adjusted by rotating the first connecting rod 31 to cause the holding members 32 to move axially, thereby matching the separation of the screen A on front frames B of different sizes.

[0055] In some embodiments, the holding members 32 are holding plates. When the holding assembly 3 is mounted on the side panel 14, the holding plates 32 in both sets of holding assemblies 3 are arranged vertically and parallel to each other. The two vertical and parallel holding plates 32 form a guide groove structure. When the holding plates 32 are aligned with the edge of the screen A during pressing, the adhesive-backed heated screen A can move along the guide groove structure after being released. This prevents the screen A from losing restraint and freely moving horizontally after being released, which could cause damage due to collision.

[0056] In some embodiments, the second connecting rod 41 is a telescopic rod, thereby enabling the movement of the heating plate 42. When the adhesive backing heats up and the screen A is removed under the push of the potential energy driving component 2, the heating plate 42 can move with the screen A, avoiding any obstruction to the screen A and ensuring that the screen A is smoothly removed from the front frame B.

[0057] The following is combined with Figures 1-3 The specific structure and working process of an embodiment of the screen disassembly device of the present invention are described as follows:

[0058] like Figure 1 As shown, the potential energy driving component 2 is installed on the bottom plate 13 of the box body 1, the heating component 4 is installed on the top plate 15 of the box body 1, and two pressing components 3 are provided and respectively installed on the side panels 14 on both sides of the box body 1. The first connecting rods 31 of the pressing components 3 are threadedly connected to the mounting holes 16 of the corresponding side panels 14.

[0059] The front frame B with screen A installed is brought into the housing 1 through the operating port 12 and placed on the drive plate 22. Pressing it downwards, the drive plate 22 approaches the bottom plate 13, compressing the elastic element 21 until the height of the front frame B is lower than the holding members 32. Rotate the two first connecting rods 31 to move both holding members 32 above the front frame B. Release the front frame B. With the elastic force of the elastic element 21 pushing the screen A, the two sides of the front frame B press against the corresponding holding members 32, as shown in the figure. Figure 2 As shown, the two pressing members 32 respectively press downward on both sides of the front frame B, and the elastic element 21 remains in a compressed state.

[0060] The heating plate 42 is lowered and attached to the screen A, thereby heating the adhesive on the back of the screen A, causing the adhesive force of the adhesive to gradually decrease. When the adhesive force of the adhesive is lower than the thrust provided by the elastic potential energy of the elastic element 21, as shown in FIG. Figure 3 As shown, the screen A is pushed upward by the driving plate 22 and separated from the front frame B, completing the separation of the screen A. Through the telescopic tube, the heating plate 42 moves with the screen B that is separated, and will not hinder the screen A from being separated from the front frame B.

[0061] In this embodiment, the distance between the two pressing members 32 is adjustable, so as to adapt to front frames B of different sizes.

[0062] The specific structure and working process of another embodiment of the screen disassembly device of the present invention are described below:

[0063] The potential energy driving component 2 is installed on the bottom plate 13 of the box body 1, the heating component 4 is installed on the top plate 15 of the box body 1, and two pressing components 3 are provided and are respectively installed on both sides of the top plate 15 of the box body 1. The first connecting rods 31 of the pressing components 3 are threadedly connected to the corresponding mounting holes 16 set on the top plate 15.

[0064] Insert the front frame B, with screen A installed, into the housing 1 through the access port 12 and place it on the drive plate 22, aligning the two sides of the front frame B with the corresponding holding members 32. Rotate the two first connecting rods 31, causing both holding members 32 to descend and press against the front frame B. Further downward pressure is applied until the drive plate is pressed down by screen A, compressing the elastic element 21 and generating elastic potential energy.

[0065] The heating plate 42 lowers onto screen A, heating the adhesive on the back of screen A and gradually reducing its adhesive strength. When the adhesive strength is lower than the thrust provided by the elastic potential energy of the elastic element 21, screen A is pushed upward by the driving plate 22 and separated from the front frame B, completing the separation of screen A. The heating plate 42 moves with the screen A as it is released, without hindering its removal from the front frame B, via the telescopic tube.

[0066] In this embodiment, the two holding members 32 can be raised and lowered, improving operational convenience. The structure to be disassembled only needs to be placed on the drive plate 22, without external pressure. The front frame B can be pressed by rotating the first transmission rod 31. Furthermore, the compression of the elastic element 21 when not heated can be adjusted, thereby adjusting the amount of stored elastic potential energy to ensure sufficient thrust to remove the screen A from the front frame B.

[0067] Through the description of multiple embodiments of the potential energy drive assembly of the present invention, it can be seen that the potential energy drive assembly embodiments of the present invention have at least one or more of the following advantages:

[0068] 1. The mechanical structure realizes the separation of the screen and the front frame. The working precision requirements of each component are low, the structure is simple and easy to operate. Even unskilled workers can complete the separation operation, and the efficiency of the disassembly work is high.

[0069] 2. The pressing distance can be adjusted to adapt to front frames of different sizes and realize the separation of the front frame and the screen.

[0070] 3. It can guide the detached screen to prevent the driver board from falling and being damaged.

[0071] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0072] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the same. Although the present invention has been described in detail with reference to preferred embodiments, persons skilled in the art should understand that the specific implementation methods of the present invention may still be modified or some technical features may be replaced by equivalents without departing from the spirit of the technical solutions of the present invention, and all of these should fall within the scope of the technical solutions claimed for protection by the present invention.
