Description

Technical Field

[0001] This application relates to the field of screen manufacturing equipment, and more specifically, to a pressure holding device. Background Technology

[0002] With the continuous development of vehicle technology, cars require more and more functions, making the central control screen an indispensable component. Currently, the assembly of central control screens mostly involves attaching the display screen to a protective frame together using adhesive to achieve requirements such as fixation and waterproofing. The adhesive needs to be pressed together to ensure full contact between the display screen and the protective frame.

[0003] For some irregularly shaped screens, existing technology uses a pressing fixture to contact the screen and apply pressure and hold it for a certain time to ensure that the adhesive fully contacts the display screen and the protective frame. However, due to differences in fixture dimensions, it is impossible to guarantee complete and effective contact with the screen, especially for curved or irregularly shaped screens. As a result, when applying pressure, it is impossible to guarantee uniform force per unit area, which affects the product qualification rate.

[0004] Therefore, there is an urgent need to provide a pressure-holding device to compensate for the shortcomings of existing technologies to a certain extent. Utility Model Content

[0005] The purpose of this application is to provide a pressure holding device that optimizes the structure of the pressure holding device to a certain extent, making the structure of the pressure holding device simpler, while realizing fixed throttling control.

[0006] To achieve the above objectives, the pressure-holding device provided by this utility model includes a support platform, a positioning mechanism, a pressing mechanism, and an air supply mechanism; the positioning mechanism is disposed on the support platform and is used to position the screen to be pressed; the pressing mechanism is located above the positioning mechanism and can move towards or away from the positioning mechanism; the pressing mechanism includes an air bag, the output end of the air supply mechanism is connected to the air bag, and the air bag, when filled with gas, can cover the entire area of ​​the positioning mechanism.

[0007] The carrying platform includes a platform body and a support frame; the support frame is vertically mounted on the platform body; the pressing mechanism further includes a lifting component and a support plate; the air bag is mounted on the support plate; the support plate is connected to the lifting component; the lifting component is connected to the support frame and can drive the support plate to move vertically toward or away from the positioning mechanism.

[0008] Specifically, the lifting assembly includes a lifting drive and a connecting frame. The lifting drive is connected to the support frame, the driving end of the lifting drive is connected to the connecting frame, and the support plate is connected to the connecting frame.

[0009] Specifically, the gas supply mechanism includes an air pump and an air delivery pipe, one end of which is connected to the output end of the air pump, and the other end is connected to the air bag.

[0010] Furthermore, the gas supply mechanism also includes a gas storage tank, the gas pump is connected to the gas storage tank, and the gas storage tank is connected to the gas bag through the gas delivery pipe.

[0011] Furthermore, the support frame forms a load-bearing space, and the gas storage tank is disposed within the load-bearing space and spaced apart from the main body of the platform.

[0012] The positioning mechanism includes a positioning clamp, which is mounted on the platform body and positioned opposite to the air bag.

[0013] Specifically, the positioning mechanism further includes a guide rail, which is laid on the platform body, and the positioning clamp is disposed on the guide rail and can slide relative to the guide rail.

[0014] Furthermore, the positioning mechanism also includes a clamp driving component, which is connected to the positioning clamp to drive the positioning clamp to slide on the guide rail.

[0015] Furthermore, the support platform is also equipped with a display screen, and the side of the air bag facing the positioning mechanism is equipped with a pressure sensor. The pressure sensor can detect the pressure between the air bag and the screen to be pressed, and the display screen is used to display the pressure sensed by the pressure sensor.

[0016] Compared with existing technologies, the pressure-holding device provided by this utility model has the following advantages:

[0017] The pressure-holding device provided by this utility model includes a support platform, a positioning mechanism, a pressing mechanism, and an air supply mechanism. The positioning mechanism is set on the support platform and is used to position the screen to be pressed. The pressing mechanism is located above the positioning mechanism and can move towards or away from the positioning mechanism. The pressing mechanism includes an air bag, and the output end of the air supply mechanism is connected to the air bag. After the air bag is filled with gas, it can cover the entire area of ​​the positioning mechanism.

[0018] This analysis shows that the support platform provides an installation foundation for the positioning mechanism, pressing mechanism, and air supply mechanism, thus providing a basis for the screen pressing process. This application, through the positioning mechanism set on the support platform, can support the screen, keeping its position fixed until pressing. Correspondingly, the pressing mechanism, positioned above the positioning mechanism and capable of moving towards or away from it, can move the air bag towards the screen until it is pressed together.

[0019] Understandably, this application utilizes an air supply mechanism to inflate the airbag, thereby using the inflation of the airbag to press the screen together. Furthermore, because the airbag adheres more closely to the screen and exhibits better conformity, it can, to some extent, eliminate the problem of uneven pressure per unit area caused by dimensional tolerances in the positioning mechanism or between the screen and the frame. This improves the pressing degree and bonding tightness between the screen and the frame, ensuring a higher product qualification rate. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] like Figure 1 Combination Figure 2 As shown, the pressure-holding device provided in this application includes a support platform 1, a positioning mechanism, a pressing mechanism, and an air supply mechanism; the positioning mechanism is set on the support platform 1 and is used to position the screen to be pressed, the pressing mechanism is located above the positioning mechanism, and the pressing mechanism can move towards or away from the positioning mechanism; the pressing mechanism includes an air bag 2, the output end of the air supply mechanism is connected to the air bag 2, and the air bag 2 can cover the entire area of ​​the positioning mechanism after being filled with gas.

[0028] Compared with existing technologies, the pressure-holding device provided by this utility model has the following advantages:

[0029] The pressure-holding device provided by this utility model provides an installation foundation for the positioning mechanism, pressing mechanism, and air supply mechanism through the support platform 1, thereby providing a foundation for the screen pressing process. The positioning mechanism on the support platform 1 supports the screen, keeping its position fixed until pressing. Correspondingly, the pressing mechanism, positioned above the positioning mechanism and capable of moving towards or away from it, moves the air bag 2 towards the screen until it is pressed against it.

[0030] Understandably, this application uses an air supply mechanism to inflate the air bag 2, thereby using the inflation of the air bag 2 to press the screen together. Furthermore, because the air bag 2 adheres more closely to the screen and has better conformability, it can, to some extent, eliminate the problem of uneven pressure per unit area caused by dimensional tolerances in the positioning mechanism or between the screen and the frame. This improves the pressing degree and adhesion tightness between the screen and the frame, ensuring a higher product qualification rate.

[0031] Optionally, such as Figure 1 Combination Figure 2As shown, the carrying platform 1 in this application includes a platform body 101 and a support frame 102; the support frame 102 is arranged vertically on the platform body 101, and the pressing mechanism also includes a lifting component and a support plate 4. The air bag 2 is arranged on the support plate 4, the support plate 4 is connected to the lifting component, the lifting component is connected to the support frame 102, and can drive the support plate 4 to move in the vertical direction toward or away from the positioning mechanism.

[0032] The lifting assembly in this application can be a motor-driven lead screw structure, or it can be a cylinder or hydraulic cylinder structure. It is understood that since this application provides an air bag 2 and an air supply mechanism, the lifting of the support plate 4 can be achieved by using a cylinder. At the same time, the air supply mechanism can be used to supply air to the air bag 2 and the cylinder, making the overall power source of the equipment simpler and saving space on the platform body 101.

[0033] Correspondingly, the support plate 4 provides a stable and sufficient installation space for the air bag 2, and can ensure the flatness of the air bag 2 to a certain extent.

[0034] Optionally, such as Figure 2 As shown, the lifting assembly in this application includes a lifting drive and a connecting frame 3. The lifting drive is connected to the support frame 102, the drive end of the lifting drive is connected to the connecting frame 3, and the support plate 4 is connected to the connecting frame 3.

[0035] like Figure 2 As shown, the connecting frame 3 in this application consists of multiple spaced right-angled triangular plates, one of which is connected to the support plate 4. In order to realize the lifting and lowering movement of the connecting frame 3, a slide rail can be set on the support frame 102, and a sliding plate is connected to the slide rail. The other right-angled side of the multiple spaced right-angled triangular plates is connected to the sliding plate. The telescopic end of the lifting and lowering drive is connected to the sliding plate. By driving the sliding plate to slide on the slide rail, the support plate 4 moves in the vertical direction, thereby realizing the lifting and lowering movement of the air bag 2, and realizing the pressure application and release of the screen to be pressed.

[0036] Optionally, such as Figure 2 As shown, the gas supply mechanism in this application includes an air pump 5 and an air delivery pipe 6. One end of the air delivery pipe 6 is connected to the output end of the air pump 5, and the other end is connected to the air bag 2.

[0037] The air pump 5 in this application is installed on the platform body 101. When it is necessary to inflate the air bag 2, the air pump 5 is started, thereby inflating the air bag 2 through the air supply pipe 6.

[0038] Preferably, the gas supply pipe 6 in this application is made of a rigid material, such as metal, which makes the wiring more organized and can withstand higher pressure. Accordingly, a pressure gauge or pressure sensor can be added to the gas supply pipe 6 to detect the pressure state inside the air bag 2. When the pressure is sufficient, the air pump 5 stops inflating to avoid over-inflating and causing the air bag 2 to burst.

[0039] Optionally, such as Figure 2 As shown, the gas supply mechanism in this application also includes a gas storage tank 7, an air pump 5 connected to the gas storage tank 7, and a gas storage tank 7 connected to the gas bag 2 via a gas delivery pipe 6.

[0040] The further designed air tank 7 can provide the air bag 2 with a more uniform, stable, and relatively clean gas. That is, the air tank 7 can filter some of the dust and water vapor carried in the gas output by the air pump 5, so that the air bag 2 can be kept clean and dry to a certain extent, thereby ensuring the stability of the screen pressing process.

[0041] Accordingly, such as Figure 2 As shown, the support frame 102 in this application forms a load-bearing space, and the gas storage tank 7 is installed in the load-bearing space and spaced apart from the platform body 101.

[0042] The support space formed by the support frame 102 allows the gas storage tank 7 to be spaced apart from the platform body 101, that is, the gas storage tank 7 is mounted away from the platform body 101, which can greatly save space on the platform body 101, allowing the platform body 101 to reserve more space for the screen and avoid interference with the screen pressing process.

[0043] Optionally, such as Figure 2 As shown, the positioning mechanism in the bonded area includes a positioning clamp 8, which is mounted on the platform body 101 and is positioned opposite to the air bag 2.

[0044] The positioning fixture 8 can stably support the screen to be pressed, and the positioning fixture 8 provided in this application can be a support structure whose shape is adapted to the screen. The screen is directly embedded in the support structure to achieve the positioning of the screen.

[0045] Optionally, such as Figure 2 As shown, the positioning mechanism in this application also includes a guide rail 9, which is laid on the platform body 101. The positioning clamp 8 is set on the guide rail 9 and can slide relative to the guide rail 9.

[0046] The positioning fixture 8 can move relative to the guide rail 9, thereby adjusting the relative position between it and the air bag 2 according to different screen shapes and sizes, thus ensuring the uniformity of force during the pressing process.

[0047] Correspondingly, the guide rail 9 can also be used to realize the detachable connection between the positioning fixture 8 and the platform body 101, thereby enabling the replacement of the positioning fixture 8. In turn, a single pressure holding device can be used to perform the pressing work of multiple screens, eliminating the need to develop and design multiple devices and greatly saving production costs.

[0048] Optionally, the positioning mechanism in this application further includes a clamp driving component, which is connected to the positioning clamp 8 to drive the positioning clamp 8 to slide on the guide rail 9.

[0049] The clamp driving component in this application can also adopt the above-mentioned telescopic structure such as a motor-driven lead screw, cylinder, or hydraulic cylinder to realize the sliding of the positioning clamp 8 on the guide rail 9.

[0050] Optionally, such as Figure 1 As shown, the support platform 1 in this application is also provided with a display screen 10, and the side of the air bag 2 facing the positioning mechanism is provided with a pressure sensor. The pressure sensor can detect the pressure between the air bag 2 and the screen to be pressed, and the display screen 10 is used to display the pressure sensed by the pressure sensor.

[0051] By setting a pressure sensor, the pressure applied to the screen to be pressed by the air bag 2 can be detected, and the display screen 10 can provide feedback, thereby ensuring the accuracy of the pressing pressure and improving the pressing effect.

[0052] Preferably, in the pressure-holding device provided in this application, an indicator light 11 may also be provided on the bearing platform 1. The indicator light 11 can provide feedback on whether the device is turned on, whether it is performing a pressing operation, or whether the pressing operation has been completed. For example, the indicator light 11 has two feedback colors. When the device is turned on, the indicator light 11 displays green. When the device is performing a pressing operation, the device displays red or yellow to warn the operator and other personnel in the site that the device is running. When the pressing operation is completed, the green light is restored to indicate that the pressing operation is completed and the device is ready to proceed with the next operation.

[0053] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
