Description

Technical Field

[0001] The utility model relates to the technical field of screen pressure-maintaining jigs, in particular to a flat-panel screen pressure-maintaining jig structure. Background Art

[0002] A tablet screen is the display part of a tablet computer, used to display information such as images, videos, and text. It is typically composed of a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display. A flat screen pressure-maintaining jig is a specialized tool used during tablet screen assembly or transportation to ensure the screen maintains flatness and pressure during the attachment process.

[0003] The existing Chinese patent with reference number CN217814371U discloses a screen pressure-maintaining jig, which includes an upper mold and a lower mold. The lower mold is used to carry the screen to be pressed so that the annular pressure plate of the upper mold presses the four edges of the screen to be pressed. A plurality of grooves or fractures are evenly arranged on the surface of the annular pressure plate pressed against the screen to be pressed, so that the space formed by the annular pressure plate pressing against the upper mold and the screen to be pressed is connected to the outside air; or the annular pressure plate is provided with air holes connected to the outside air on the plate body surrounding the upper mold. The jig of the utility model is provided with a plurality of grooves or fractures on the pressing surface of the annular pressure plate, or air holes are provided on the plate body within the range of the annular pressure plate surrounding the upper mold, so that the space between the annular pressure plate and the screen is not easily negatively pressurized, thereby avoiding instantaneous suction when the upper mold and the screen are separated, and improving the damage prevention effect of maintaining pressure on the screen.

[0004] Although this patent has the effect of setting air holes to prevent negative pressure from being formed, it does not have the function of buffering impact force. When the screen placed in the jig is under pressure, the jig itself may cause pressure damage to the screen due to the lack of relevant structure to buffer the impact force. When using it, the operator also needs to put on a layer of protective equipment or structure, which increases the process and reduces work efficiency. The structure also needs to be further processed and improved. For this reason, the inventor proposed a flat screen pressure-maintaining jig structure to solve the above-mentioned technical problem of reducing the pressure on the screen when the screen is placed in the jig. Utility Model Content

[0005] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.

[0006] A flat-panel screen pressure-maintaining fixture structure includes a base plate and positioning blocks. The positioning blocks are L-shaped and symmetrically arranged on the surface of the base plate. The surface of the positioning blocks is provided with a plurality of connection holes. The connection holes are stepped holes, one end of which passes through the surface of the base plate. The area between the base plate and the positioning blocks is a placement area for placing a semi-finished flat-panel screen front cover. The end of the base plate opposite the placement area is a pressure-maintaining area. The pressure-maintaining area includes a soft pad, a sponge layer, and a magnetic plate. The outer side of the pressure-maintaining area is connected to a limit ring, the surface of the limit ring being higher than the surface of the pressure-maintaining area. A buffer assembly is provided between the soft pad and the magnetic plate.

[0007] The flat-panel screen pressure-maintaining fixture structure maintains pressure on the TP capacitive screen and the front case by stacking them. As the number of stacked pieces increases, the bottom flat-panel screen pressure-maintaining fixture structure is subjected to the greatest pressure. A soft pad, sponge layer, and magnetic plate are used to initially cushion the TP capacitive screen and the front case to avoid rigid contact. A buffer component is also added to buffer the pressure to prevent excessive pressure from the bottom flat-panel screen pressure-maintaining fixture, which could damage the flat-panel screen surface.

[0008] In addition, the stackable method further facilitates the transportation and placement of this product, saving space while facilitating transportation and handling, thereby improving transportation efficiency and work efficiency. The pressure-holding function is achieved by two adjacent pressure-holding fixtures. This method does not require the use of additional mechanical equipment, saving costs while maintaining pressure through mutual constraints between the two, further improving work efficiency.

[0009] Furthermore, the sponge layer is located between the soft pad and the magnetic plate, and the buffer assembly includes a rubber rod and a buffer spring. The rubber rod is located inside the buffer spring, and both ends of the buffer spring are connected to a top plate. The surface of the top plate is respectively in contact with the soft pad and one end of the magnetic plate. A connecting plate for preventing the sponge layer from falling off is installed in the middle of the rubber rod, and the connecting plate is embedded in the sponge layer.

[0010] The connecting plate embedded in the sponge layer can enhance the fixation between the sponge layer and the buffer assembly, prevent the sponge layer from falling off when subjected to external force, thereby improving the stability and service life of the entire buffer assembly. When maintaining pressure, the surface of the flat screen fits the surface of the cushion, and then when force is applied, the sponge layer, the rubber rod and the buffer spring are compressed. This structure provides a reaction force during compression to further pressurize the surface of the cushion on the surface of the flat screen. After applying the specified pressure, when subjected to additional impact force, the elasticity of the buffer spring can buffer the impact force, thereby achieving the effect of protecting the flat screen and avoiding excessive pressure that may cause the flat screen to shatter.

[0011] Furthermore, the outer side surface of the limiting ring is connected to a support plate, and a plurality of pressure-maintaining magnets are provided on the surface of the bottom plate, and the pressure-maintaining magnets are linearly arranged on the surface of the bottom plate; this structure can effectively improve the stability of the pressure-maintaining jig when stacking, reduce its shaking during the stacking process, and at the same time share the load-bearing capacity of the support plate, thereby ensuring the stability and reliability of the pressure-maintaining jig when stacking, and generating magnetic attraction through the pressure-maintaining magnets to reduce the deviation of the pressure-maintaining jig when stacking, thereby reducing the probability of falling during stacking.

[0012] Furthermore, the pressure-maintaining area is provided with an installation groove for accommodating the soft pad, sponge layer and magnetic plate, and the installation groove and the soft pad, sponge layer and magnetic plate are gap-fitted. The gap-fitting setting can ensure that the soft pad, sponge layer and magnetic plate can be easily installed and removed in the installation groove, while maintaining stable positioning, avoiding damage caused by over-tight assembly, and also helping to reduce the impact of assembly errors on overall performance. In addition, when part of the structure of the soft pad, sponge layer or magnetic plate is damaged, it can be replaced individually by disassembly, which reduces maintenance costs while ensuring the pressure-maintaining performance of the pressure-maintaining area.

[0013] Furthermore, there is a buffer gap between the base plate and the positioning block; this structure is used to reduce the direct impact between the base plate and the positioning block, protecting both from damage when subjected to external forces, and avoiding direct contact between the base plate and the positioning block. It also helps prevent corrosion between the two adjacent components, thereby extending the service life. At the same time, the buffer gap also helps to reduce noise and vibration, and improve the stability and reliability of the pressure-holding jig when stacking.

[0014] Furthermore, a calibration groove for assisting stacking is provided at the bottom of the base plate. The calibration groove is a concave structure, extending toward both ends of the base plate and passing through both ends of the base plate. A calibration block is provided on the surface of the positioning block for use with the calibration groove.

[0015] The calibration block on the surface of the positioning block can be paired with the calibration groove at the bottom of the base plate, which helps to improve the accuracy and stability during the stacking process, ensure the docking between two adjacent components, and reduce installation errors. When the base plate is stacked with another pressure-holding fixture of the same structure, the calibration block of the positioning block on the surface of the other pressure-holding fixture of the same structure is clamped through the calibration groove of the base plate. This way, the stacking is neat and aligned, while reducing the probability of falling. The raised calibration block and the calibration groove of the groove structure are clamped together to play the role of the mortise and tenon structure, further increasing the connection stability of the stack.

[0016] Compared with the prior art, the present invention has the following beneficial effects: the TP capacitive screen and the front shell are pressure-maintained by stacking them. As the number of stacked pieces increases, the pressure on the bottom flat screen pressure-maintaining fixture structure is the greatest. A soft pad, a sponge layer, and a magnetic plate are used to initially buffer the TP capacitive screen and the front shell to avoid rigid contact. At the same time, a buffer component is added to buffer the pressure, preventing the pressure of the bottom flat screen pressure-maintaining fixture from being too high and causing damage to the flat screen surface.

[0017] In addition, the stackable method further facilitates the transportation and placement of this product, saving space while facilitating transportation and handling, thereby improving transportation efficiency and work efficiency. The pressure-maintaining function is achieved by two adjacent pressure-maintaining fixtures. This method does not require the use of additional mechanical equipment, saving costs, while maintaining pressure through mutual constraints between the two, further improving work efficiency.

[0018] In addition, when the cushion, sponge layer or part of the magnetic plate structure is damaged, they can be replaced individually by disassembly, which reduces maintenance costs while ensuring the pressure-holding performance of the pressure-holding area. During pressure holding, the surface of the flat screen fits against the surface of the cushion, and then when force is applied, the sponge layer and the buffer component are compressed. The buffer component provides a reaction force during compression to further pressurize the surface of the cushion against the surface of the flat screen. After applying the specified pressure, when subjected to additional impact force, the buffer component can buffer the impact force, thereby protecting the flat screen and preventing the flat screen from being broken due to excessive pressure.

DETAILED DESCRIPTION

[0031] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0032] For this example, please refer to Figures 1-11 , a flat screen pressure holding fixture structure specifically implemented therein includes a bottom plate 1 and a positioning block 2, the positioning block 2 is L-shaped and symmetrically arranged on the surface of the bottom plate 1, a plurality of connecting holes 3 are provided on the surface of the positioning block 2, the connecting holes 3 are stepped holes, the connecting holes 3 are used to install connecting rods, and the bottom plate 1 and the positioning block 2 are connected by the connecting rods, one end of the connecting hole 3 passes through the surface of the bottom plate 1, the area between the bottom plate 1 and the positioning block 2 is a placement area 4 for placing a semi-finished product of a flat screen front shell, the end of the bottom plate 1 opposite to the placement area 4 is a pressure holding area 5, the pressure holding area 5 includes a soft pad 6, a sponge layer 7 and a magnetic plate 8, the outer side of the pressure holding area 5 is connected to a limiting ring 9, the surface of the limiting ring 9 is higher than the surface of the pressure holding area 5, and a buffer component is provided between the soft pad 6 and the magnetic plate 8;

[0033] The flat screen pressure-maintaining jig structure maintains pressure on the TP capacitive screen and the front shell by stacking them. As the number of stacked pieces increases, the bottom flat screen pressure-maintaining jig structure is subjected to the greatest pressure. A soft pad 6, a sponge layer 7, and a magnetic plate 8 are used to initially buffer the TP capacitive screen and the front shell to avoid rigid contact. A buffer component is also added to buffer the pressure to prevent excessive pressure from the bottom flat screen pressure-maintaining jig from damaging the flat screen surface.

[0034] In addition, the stackable method further facilitates the transportation and placement of this product, saving space while facilitating transportation and handling, thereby improving transportation efficiency and work efficiency. The pressure-holding function is achieved by two adjacent pressure-holding fixtures. This method does not require the use of additional mechanical equipment, saving costs while maintaining pressure through mutual constraints between the two, further improving work efficiency.

[0035] The sponge layer 7 is located between the soft pad 6 and the magnetic plate 8. The buffer assembly includes a rubber rod 10 and a buffer spring 11. The rubber rod 10 is located inside the buffer spring 11. Both ends of the buffer spring 11 are connected to a top plate 12. The surface of the top plate 12 is respectively attached to the soft pad 6 and one end of the magnetic plate 8. A connecting plate 13 for preventing the sponge layer 7 from falling off is installed in the middle of the rubber rod 10. The connecting plate 13 is embedded in the interior of the sponge layer 7.

[0036] The connecting plate 13 embedded in the sponge layer 7 can enhance the fixation between the sponge layer 7 and the buffer assembly, and prevent the sponge layer 7 from falling off when subjected to external force, thereby improving the stability and service life of the entire buffer assembly. When the pressure is maintained, the surface of the flat screen fits the surface of the soft cushion 6, and then when the force is applied, the sponge layer 7 and the rubber soft rod 10 and the buffer spring 11 are compressed. This structure provides a reaction force during compression to further cause the surface of the soft cushion 6 to pressurize the surface of the flat screen. After applying the specified pressure, when subjected to additional impact force, the elasticity of the buffer spring 11 can buffer the impact force, thereby achieving the effect of protecting the flat screen and avoiding excessive pressure that may cause the flat screen to break.

[0037] The outer side of the limiting ring 9 is connected to a support plate 14, and a plurality of pressure-maintaining magnets 15 are provided on the surface of the bottom plate 1, and the pressure-maintaining magnets 15 are linearly arranged on the surface of the bottom plate 1; this structure can effectively improve the stability of the pressure-maintaining jig when stacking, reduce its shaking during the stacking process, and at the same time share the load-bearing capacity of the support plate 14, ensuring the stability and reliability of the pressure-maintaining jig when stacking, and generating magnetic attraction through the pressure-maintaining magnets 15 to reduce the deviation of the pressure-maintaining jig when stacking, thereby reducing the probability of falling during stacking.

[0038] The pressure-holding area 5 is provided with a mounting groove 19 for accommodating the soft pad 6, the sponge layer 7 and the magnetic plate 8, and the mounting groove 19 and the soft pad 6, the sponge layer 7 and the magnetic plate 8 are clearance-fitted. The clearance-fitting setting can ensure that the soft pad 6, the sponge layer 7 and the magnetic plate 8 can be easily installed and removed in the mounting groove 19, while maintaining stable positioning, avoiding damage caused by over-tightening of the assembly, and also helping to reduce the impact of assembly errors on the overall performance. In addition, when part of the structure of the soft pad 6, the sponge layer 7 or the magnetic plate 8 is damaged, it can be replaced individually by disassembly, which reduces the maintenance cost while ensuring the pressure-holding performance of the pressure-holding area 5. Figure 11 As shown, the red area is the holding area 20 in the superimposed state.

[0039] There is a buffer gap 16 between the base plate 1 and the positioning block 2; this structure is used to reduce the direct impact between the base plate 1 and the positioning block 2, protecting both from damage when subjected to external forces, avoiding direct contact between the base plate 1 and the positioning block 2, and helping to prevent corrosion between the two adjacent components, thereby extending the service life. At the same time, the buffer gap 16 also helps to reduce noise and vibration, and improve the stability and reliability of the pressure-holding fixture when stacking.

[0040] The bottom of the base plate 1 is provided with a calibration groove 17 for assisting stacking. The calibration groove 17 is a concave structure. The calibration groove 17 extends toward both ends of the base plate 1 and passes through both ends of the base plate 1. The surface of the positioning block 2 is provided with a calibration block 18 used in conjunction with the calibration groove 17.

[0041] The calibration block 18 on the surface of the positioning block 2 can be paired with the calibration groove 17 at the bottom of the base plate 1, which helps to improve the accuracy and stability during the stacking process, ensure the docking between two adjacent components, and reduce installation errors. When the base plate 1 is stacked with another pressure-holding fixture of the same structure, the calibration block 18 of the positioning block 2 on the surface of another pressure-holding fixture of the same structure is clamped through the calibration groove 17 of the base plate 1. This way, the stacking is neat and aligned, while reducing the probability of falling. The clamping of the raised calibration block 18 and the calibration groove 17 of the groove structure plays a cooperating role in the mortise and tenon structure, further increasing the connection stability of the stack.

[0042] The operation process of the present invention is as follows: the TP capacitive screen and the front shell are pressure-maintained by stacking them. When the number of stacks increases, the pressure on the flat screen pressure-maintaining fixture structure at the bottom is the greatest. The soft pad 6, the sponge layer 7 and the magnetic plate 8 are used to initially buffer the TP capacitive screen and the front shell to avoid rigid contact. At the same time, a buffer component is added to buffer the pressure to prevent the pressure of the flat screen pressure-maintaining fixture at the bottom from being too high and causing damage to the surface of the flat screen.

[0043] In addition, the stackable method further facilitates the transportation and placement of this product, saving space while facilitating transportation and handling, thereby improving transportation efficiency and work efficiency. The pressure-maintaining function is achieved by two adjacent pressure-maintaining fixtures. This method does not require the use of additional mechanical equipment, saving costs, while maintaining pressure through mutual constraints between the two, further improving work efficiency.

[0044] In addition, when the cushion 6, sponge layer 7 or magnetic plate 8 is partially damaged, it can be replaced individually by disassembling, which reduces maintenance costs while ensuring the pressure holding performance of the pressure holding area 5.

[0045] When maintaining pressure, the surface of the flat screen fits against the surface of the soft pad 6, and then when a force is applied, the sponge layer 7, the rubber soft rod 10 and the buffer spring 11 are compressed. This structure provides a reaction force during compression to further cause the surface of the soft pad 6 to pressurize the surface of the flat screen. After applying a specified pressure, when an additional impact force is applied, the elasticity of the buffer spring 11 can buffer the impact force, thereby achieving the effect of protecting the flat screen and preventing the flat screen from being broken by excessive pressure.

[0046] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all of these should be considered as within the scope of protection of the present invention.
