Description

Technical Field

[0001] This utility model relates to the field of flexible board processing technology, and in particular to a flexible board curved surface pressing calibration device. Background Technology

[0002] Flexible sheets are widely used in modern electronics, aerospace, wearable devices, and other fields due to their lightweight, thinness, bendability, and high flexibility. However, during the manufacturing process of flexible sheets, due to the influence of material properties and processing technology, a certain degree of strain rebound often occurs after the curved surface pressing process is completed.

[0003] Currently, the traditional method for addressing strain rebound in flexible sheets involves pre-setting a fixed pre-camber value on the pressing arc seat to offset potential subsequent strain rebound and ensure the final forming accuracy of the flexible sheet. However, this method has significant drawbacks. Because flexible sheets made of different materials have varying mechanical properties such as elastic modulus and Poisson's ratio, the resulting strain values ​​after processing differ. A fixed pre-camber value cannot meet the actual needs of flexible sheets made of different materials, leading to poor applicability when dealing with diverse flexible sheet materials. This makes it difficult to guarantee the processing accuracy of various flexible sheets, hindering the high-quality application and development of flexible sheets in more fields.

[0004] To address the aforementioned issues, we propose a flexible plate curved surface pressing calibration device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flexible plate curved surface pressing calibration device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flexible board curved surface pressing and calibration device includes a processing platform. A pressure-bearing component and a curved panel pressing component are sequentially arranged on the upper side of the processing platform. The curved panel pressing component includes an upper arc plate. The upper arc plate has first rotating grooves symmetrically opened on both sides. An upper tail arc plate is rotatably installed inside the first rotating grooves. Structural folding plates are symmetrically fixedly installed on the upper side of the upper arc plate. A second hydraulic rod is hinged between the structural folding plate and the upper tail arc plate. A structural top plate is fixedly installed on the upper side of the structural folding plate. An electromagnet is embedded in the inner side of the upper arc plate. The upper tail arc plate is smoothly connected to the upper arc plate.

[0008] Furthermore, the pressure-bearing component includes an arc seat, which is fixedly installed on the upper side of the processing platform. A lower arc plate is fixedly installed on the upper side of the arc seat. A second rotating groove is symmetrically opened on both sides of the lower arc plate. A lower tail arc plate is rotatably installed inside the second rotating groove. The lower tail arc plate is smoothly connected to the lower arc plate.

[0009] Furthermore, a sliding groove is provided on the inner side of the arc seat, and a supporting arc block is slidably arranged at the two ends of the sliding groove, the supporting arc block being located on the bottom side of the lower tail arc plate.

[0010] Furthermore, a partition plate is fixedly installed at the middle position of the inner side of the slide, and electric telescopic rods are symmetrically fixedly installed on both sides of the partition plate. The output end of the electric telescopic rod is fixedly connected to the inner side of the support arc block.

[0011] Furthermore, a support gantry is fixedly installed on the upper side of the processing platform, and a first hydraulic rod is fixedly installed on the lower side of the support gantry. The output end of the first hydraulic rod is fixedly connected to the upper side of the top plate of the structure.

[0012] Furthermore, a pressure sensor is fixedly installed inside the output end of the first hydraulic rod.

[0013] Furthermore, a controller is fixedly installed on the side wall of the supporting gantry.

[0014] Furthermore, a stiffening plate is fixedly connected to the lower bend of the structural fold plate.

[0015] Compared with related technologies, the flexible plate curved surface pressing calibration device proposed in this utility model has the following beneficial effects:

[0016] In this invention, a flexible plate curved surface pressing calibration device is provided. Through the setting of a curved plate upper pressing component and a bearing component, the upper tail arc plate of the upper arc plate in the upper pressing component can control the pre-arch value of the tail arc plate by controlling the extension and retraction of the second hydraulic rod. The lower tail arc plates on both sides of the lower arc plate can adapt to the pressing of the flexible plate placed on the lower arc plate by adaptive rotation, and cooperate to apply the pre-arch value to the end of the flexible plate to counteract the rebound deformation of the material after bending and pressing, thereby improving the processing accuracy. At the same time, the downward pressing rotation angle of the upper tail arc plate has a controllable adjustment function, so that this invention can apply different pre-arch values ​​to adapt to the bending processing of plates of different thicknesses or materials, with a wide range of applications. In addition, the electromagnet embedded in the inner side of the upper arc plate can lift the relevant flexible metal plate upward after pressing is completed and energized, so as to facilitate the observation of the shape of the plate after pressing.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-5 A flexible board curved surface pressing calibration device includes a processing platform 1, on which a pressure-bearing component 6 and a curved panel pressing component 5 are sequentially arranged; the curved panel pressing component 5 includes an upper arc plate 51, with first rotating grooves 52 symmetrically opened on both sides of the upper arc plate 51, an upper tail arc plate 53 rotatably installed inside the first rotating grooves 52, a structural folding plate 54 symmetrically fixedly installed on the upper side of the upper arc plate 51, a second hydraulic rod 56 hinged between the structural folding plate 54 and the upper tail arc plate 53, a structural top plate 57 fixedly installed on the upper side of the structural folding plate 54, an electromagnet 58 embedded inside the upper arc plate 51, and the upper tail arc plate 53 smoothly connected to the upper arc plate 51.

[0025] With the above-mentioned setup, the upper tail arc plate 53 and the upper arc plate 51 are smoothly connected, so that when the upper tail arc plate 53 and the upper arc plate 51 press the flexible plate simultaneously, the flexible plate can generate a smooth arc surface. After the pressing is completed, the second hydraulic rod 56 is used to push the upper tail arc plate 53 to flip slightly downward, thereby increasing the pre-arch value of the ends of both sides of the flexible plate after pressing, so as to counteract the rebound deformation of the material.

[0026] In this configuration, a stiffening plate 55 is fixedly connected to the lower bend of the structural fold plate 54.

[0027] By setting up the stiffening plate 55 as described above, the structural strength of the structural folding plate 54 is increased, enabling the structural folding plate 54 to provide stable support to the second hydraulic rod 56.

[0028] In this method, the pressure-bearing component 6 includes an arc seat 61, which is fixedly installed on the upper side of the processing platform 1. A lower arc plate 62 is fixedly installed on the upper side of the arc seat 61. A second rotating groove 63 is symmetrically opened on both sides of the lower arc plate 62. A lower tail arc plate 64 is rotatably installed inside the second rotating groove 63. The lower tail arc plate 64 is smoothly connected to the lower arc plate 62. A sliding groove 65 is opened inside the arc seat 61. A supporting arc block 66 is slidably arranged at the two ends of the sliding groove 65. The supporting arc block 66 is located on the bottom side of the lower tail arc plate 64. A partition plate 67 is fixedly installed in the middle of the inner side of the sliding groove 65. Electric telescopic rods 68 are symmetrically fixedly installed on both sides of the partition plate 67. The output end of the electric telescopic rod 68 is fixedly connected to the inner side of the supporting arc block 66.

[0029] With the above-mentioned setup, the supporting arc block 66 at the bottom of the lower tail arc plate 64 provides support for the lower tail arc plate 64. After the initial pressing of the flexible plate is completed, the electric telescopic rod 68 retracts, causing the supporting arc blocks 66 on both sides to slide inward into the slide groove 65. At this time, the bottom of the lower tail arc plate 64 has no support. When the lower side of the upper tail arc plate 53 rotates slightly to apply a pre-arch value to both sides of the curved plate, the lower tail arc plate 64 follows and flips downward, without interfering with the pressing process of the upper tail arc plate 53.

[0030] In this method, a support gantry 2 is fixedly installed on the upper side of the processing platform 1, a first hydraulic rod 4 is fixedly installed on the lower side of the support gantry 2, the output end of the first hydraulic rod 4 is fixedly connected to the upper side of the structural top plate 57, a pressure sensor is fixedly installed inside the output end of the first hydraulic rod 4, and a controller 3 is fixedly installed on the side wall of the support gantry 2.

[0031] With the above settings, the controller 3 controls the first hydraulic rod 4 to start and drive the upper arc plate 51 to press down, so that the pressure value of the flexible plate placed on the upper side of the lower arc plate 62 is completely in contact with the lower arc plate 62 at the bottom. The pressure value is gradually increased until the output pressure value of the first hydraulic rod 4 reaches the preset value of the controller 3 and then stops. The subsequent operation of adding the pre-arch value begins.

[0032] The working principle of the flexible plate curved surface pressing calibration device provided by this utility model is as follows:

[0033] In operation, the controller 3 activates the first hydraulic rod 4, whose output pushes the top plate 57 of the structure, thereby causing the upper arc plate 51 of the curved panel pressing assembly 5 to move downwards. The upper tail arc plates 53, smoothly connected to both sides of the upper arc plate 51, move downwards together with the upper arc plate 51, gradually pressing down the flexible plate placed on the lower arc plate 62. During this process, the pressure sensor inside the output of the first hydraulic rod 4 monitors the pressure value in real time and feeds the data back to the controller 3. As pressure is applied, the flexible plate gradually adheres to the lower arc plate 62. When the pressure reaches the preset value of the controller 3, the first hydraulic rod 4 stops pressing down, completing the initial pressing of the flexible plate and shaping it into a curved surface that matches the lower arc plate 62. After the initial pressing is completed, the electric telescopic rod 68 is activated to retract. The electric telescopic rod 68 drives the supporting arc blocks 66 on both sides to slide into the groove 65 on the inner side of the arc seat 61, thereby removing the support for the lower tail arc plate 64. Then, the controller 3 controls the second hydraulic rod 56 to extend. The second hydraulic rod 56 pushes the upper tail arc plate 53 to rotate slightly downward around the first rotating groove 52, thus pressing the two sides of the flexible plate together. A pre-arch value is applied to the side end. Since the bottom of the lower tail arc plate 64 loses support, when the upper tail arc plate 53 on the lower side is pressed down and rotated, the lower tail arc plate 64 can adaptively rotate within the second rotating groove 63 and flip downward following the pressing action of the upper tail arc plate 53. This will not interfere with the pressing process of the upper tail arc plate 53. The two work together to complete the application of the pre-arch value to the end of the flexible plate, in order to counteract the rebound deformation of the material after bending and pressing. According to the requirements of different flexible plate materials and thicknesses, the pressing and rotating angle of the upper tail arc plate 53 can be precisely controlled by adjusting the extension and retraction of the second hydraulic rod 56, thereby applying different sizes of pre-arch values ​​to adapt to diverse processing requirements.
