[0002] Radio frequency heating is a technology that uses electromagnetic waves with a frequency of 3kHz to 300MHz to heat materials. This heating method has many advantages: the rate of radio frequency heating is very fast, and the high-frequency alternating electromagnetic waves can quickly make the molecules in the material move at high speed, achieving the effect of rapid heating. This heating method also has the characteristics of overall heating inside and outside, which can ensure that the material is heated evenly and avoid local overheating or underheating.

[0003] At present, as customized furniture is becoming increasingly popular, various special-shaped furniture has emerged. In the processing of doors, walls and cabinets, an arc plate making device is needed to press or bend the wooden board into an arc bent board with a certain arc surface or angle. The arc plate making device uses a radio frequency heater to heat and soften the wooden board to make its internal fiber structure soft, which is convenient for subsequent curing and molding. The arc plate making device mainly includes a device body, a supporting platform fixed in the device body, a mold arranged above the supporting platform, a buckle cover arranged on the top of the device body, and a plurality of radio frequency heaters arranged on the buckle cover; however, because the upper surface of the mold is an arc, when placing the plate-like profile, the plate-like profile needs to be at the top of the arc of the mold, and its state is extremely unstable and easily displaced by external force, and the position of the plate-like profile needs to be adjusted by visual inspection and experience of the staff, which not only has low positioning accuracy, but also has difficulty in positioning and high scrap rate. Summary of the invention

[0004] In order to facilitate the stable placement of the plate-like profile on the arc top of the mold, improve the positioning accuracy of the plate-like profile, and reduce the positioning difficulty and scrap rate, the present application provides an arc plate manufacturing device and manufacturing process.

[0005] In the first aspect, the present application provides a circular arc plate manufacturing device, which adopts the following technical solution: A circular arc plate manufacturing device, comprising a frame, a device body arranged on the frame, a bearing platform fixed in the device body, a mold arranged above the bearing platform, a buckle cover arranged on the top of the device body, and a plurality of radio frequency heaters arranged on the buckle cover; A negative pressure branch pipe is arranged on the bearing platform, a plurality of negative pressure branch pipes are arranged and the negative pressure branch pipes are connected to the interior of the molding chamber; A negative pressure main pipeline is arranged between the plurality of negative pressure branch pipelines and is in communication with the plurality of negative pressure branch pipelines. A first electric-controlled valve is arranged on the negative pressure main pipeline. A vacuum pump device, arranged on the frame and connected to the negative pressure main pipeline; A fixing frame, disposed between the buckle cover and the device body and hinged to the device body; A flexible plastic film is arranged on the fixing frame and is located above the mold; The positioning and fixing mechanism comprises a positioning component and a fixing component; the positioning component is arranged on the mold, and is used to automatically align and position the plate-like profile relative to the center of the mold; the fixing component is arranged between the mold and the vacuum pump device, and is used to fix the aligned and positioned plate-like profile.

[0006] By adopting the above technical scheme, when making an arc plate with a plate-like profile, the plate-like profile is first placed on the top of the mold above the supporting platform, and then the plate-like profile is automatically aligned and positioned by the positioning component to ensure that the plate-like profile is accurately placed on the top of the arc of the mold. Subsequently, the fixing component uses the negative pressure of the vacuum pump device to firmly adsorb the plate-like profile on the mold to prevent it from shifting during the heating and forming process; after the plate-like profile is firmly fixed, the staff rotates the fixing frame to cover the top of the plate-like profile with the flexible plastic film, and then closes the buckle cover and starts the radio frequency heater to heat the plate-like profile above the mold. The high-frequency electromagnetic waves of the radio frequency heating make the molecules inside the wooden board move at high speed, quickly softening the fiber structure of the wooden board. At the same time, the vacuum pump device vacuums the space between the flexible plastic film and the supporting platform through the negative pressure branch pipe. With the action of the radio frequency heater and the negative pressure, the plate-like profile gradually softens and begins to fit the arc shape of the mold, and the plate-like profile gradually solidifies to finally form the required arc shape; after the molding is completed, the staff opens the buckle cover and safely removes the molded arc plate from the mold; wherein, through the cooperation of the positioning component and the fixing component in the positioning and fixing mechanism, the plate-like profile can be automatically positioned, calibrated and fixed relative to the center of the mold, so that when the staff covers the flexible molding film, the plate-like profile is not easily displaced due to the external force of the flexible molding film, thereby improving the positioning accuracy of the plate-like profile on the mold, reducing the error of manual visual inspection and experience adjustment, and at the same time, the plate-like profile is also firmly fixed during the heating and molding process, which improves the stability of the arc plate in the production process and the quality of the finished product, and reduces the scrap rate.

[0007] Optionally, the positioning component includes: There are two moving blocks, which are respectively located on both sides of the mold, and each of the moving blocks is rotatably connected to a rotating shaft; An arc-shaped positioning plate is fixedly mounted on the rotating shaft, and the arc-shaped positioning plates on the two rotating shafts are symmetrically arranged. A receiving groove is provided on the mold, and the arc-shaped positioning plate can be rotatably received in the receiving groove; A positioning clamping claw is arranged at one end of the arc-shaped positioning plate away from the rotating shaft and is located at a side of the arc-shaped positioning plate close to the mold; A rotating component, disposed between the moving block and the rotating shaft, and used to drive the rotating shaft to rotate; The moving component is arranged between the mold and the two moving blocks, and is used for synchronously driving the two moving blocks to move toward or away from the mold.

[0008] By adopting the above technical solution, before starting positioning, the moving block and the arc-shaped positioning plate are both stored in the storage groove on the mold and are an integral part of the mold; when the plate-like profile needs to be positioned, the moving component first synchronously drives the two moving blocks to move away from the center of the mold until the moving blocks reach the predetermined position, and then the rotating component is started to drive the rotating shaft to rotate, so that the arc-shaped positioning plate rotates toward the outside of the storage groove, and then the staff places the plate-like profile on the top of the mold, and at the same time, the positioning claws on the arc-shaped positioning plates on both sides of the plate-like profile clamp the plate-like profile, and then the moving component synchronously drives the two moving blocks to move closer to the center of the mold, so that the positioning claws drive the plate-like profile to automatically align with the center of the mold to ensure that it is accurately placed on the top of the arc. , and then the fixing component can fix the position of the plate-like profile; after the plate-like profile is fixed, the two moving blocks are synchronously driven by the moving component to move away from the center of the mold, so that the positioning clamp plate-like profile is separated, and the rotating component drives the rotating shaft and the arc-shaped positioning plate to rotate toward the side close to the storage groove, and after restoring the initial state, the moving component drives the moving block and the arc-shaped positioning plate to retract into the storage groove, so that the mold forms a complete whole, and the precise positioning and fixing of the plate-like profile can be completed; through the precise control of the moving component and the rotating component, the positioning component can align the center of the plate-like profile, significantly improve the positioning accuracy of the plate-like profile, reduce the error of manual operation and the scrap caused by inaccurate positioning, and improve the yield rate.

[0027] The following is combined with Figure 1-Figure 8 This application is described in further detail.

[0028] The present application embodiment discloses a circular arc plate manufacturing device. Figure 1-Figure 4The arc plate manufacturing device includes a frame 1, on which a device body 2 is arranged, and a bearing platform 21 is fixedly arranged in the device body 2. A mold 3 is arranged above the bearing platform 21, and a buckle cover 22 is arranged on the top of the device body 2, and a plurality of radio frequency heaters 23 are arranged on the buckle cover 22. A plurality of negative pressure branch pipes 4 are arranged on the bearing platform 21, and the plurality of negative pressure branch pipes 4 are connected to the inside of the molding bin, and a negative pressure main pipe 5 is arranged between the plurality of negative pressure branch pipes 4, and the negative pressure main pipe 5 is connected to the plurality of negative pressure branch pipes 4, and a first electric control valve is also arranged on the negative pressure main pipe 5. A vacuum pump device 6 is arranged on the frame 1, and the vacuum pump device 6 is connected to the negative pressure main pipe 5. A fixing frame 7 is arranged between the buckle cover 22 and the device body 2, and the fixing frame 7 is hinged to the device body 2. A flexible plastic film 71 is arranged on the fixing frame 7, and the flexible plastic film 71 is located above the mold 3, and the flexible plastic film 71 is made of silicone material. A gas spring 72 is provided between the fixed frame 7 and the device body 2. The gas spring 72 provides a supporting force between the fixed frame 7 and the device body 2 to balance the weight of the fixed frame 7, so that the fixed frame 7 is more stable when opened and closed, and reduces shaking and impact during operation.

[0029] Reference Figure 2 and Figure 5 The arc plate manufacturing device also includes a positioning and fixing mechanism 8, which includes a positioning component 81 and a fixing component 82; wherein the positioning component 81 is arranged on the mold 3, and is used to automatically align and position the plate-like profile relative to the center of the mold 3. The fixing component 82 is arranged between the mold 3 and the vacuum pump device 6, and is used to fix the aligned and positioned plate-like profile.

[0030] When making an arc plate from a plate-like profile, first place the plate-like profile on the top of the mold 3 above the support platform 21, and then automatically align the center of the plate-like profile through the positioning component 81 to ensure that the plate-like profile is accurately placed on the top of the arc of the mold 3. Subsequently, the fixing component 82 uses the negative pressure of the vacuum pump device 6 to firmly adsorb the plate-like profile on the mold 3 to prevent it from shifting during the heating and molding process. After the plate-like profile is firmly fixed, the staff rotates the fixing frame 7 so that the flexible plastic film 71 covers the top of the plate-like profile, then closes the buckle cover 22, and starts the radio frequency heater 23 to heat the plate-like profile above the mold 3. The high-frequency electromagnetic waves of radio frequency heating make the molecules inside the wooden board move at high speed, quickly softening the fiber structure of the wooden board.

[0031] At the same time, the vacuum pump device 6 evacuates the space between the flexible molding film 71 and the carrier 21 through the negative pressure branch pipe 4. With the action of the radio frequency heater 23 and the negative pressure, the plate-like profile gradually softens and begins to fit the arc shape of the mold 3. The plate-like profile gradually solidifies and finally forms the required arc shape. After the molding is completed, the staff opens the buckle cover 22 and safely removes the molded arc plate from the mold 3. Among them, through the cooperation of the positioning component 81 and the fixing component 82 in the positioning and fixing mechanism 8, the plate-like profile can be automatically positioned, calibrated and fixed relative to the center of the mold 3, so that when the staff covers the flexible molding film 71, the plate-like profile is not easily displaced due to the external force of the flexible molding film 71, thereby improving the positioning accuracy of the plate-like profile on the mold 3 and reducing the error of manual visual inspection and experience adjustment. At the same time, the plate-like profile is also firmly fixed during the heating and molding process, which improves the stability of the arc plate in the production process and the quality of the finished product, and reduces the scrap rate.

[0032] Reference Figure 5 and Figure 6 The positioning assembly 81 includes two moving blocks 811 respectively arranged on both sides of the width direction of the mold 3, and each moving block 811 is rotatably connected to a rotating shaft 812. An arc-shaped positioning plate 813 is fixedly arranged on the rotating shaft 812, and the arc-shaped positioning plates 813 on the two rotating shafts 812 are symmetrically arranged; a storage groove 31 is provided on the mold 3, and the arc-shaped positioning plate 813 can be rotatably stored in the storage groove 31. A positioning clamp 814 is arranged at one end of the arc-shaped positioning plate 813 away from the rotating shaft 812, and the positioning clamp 814 is located on the side of the arc-shaped positioning plate 813 close to the mold 3. A rotating component 815 is arranged between the moving block 811 and the rotating shaft 812, and the rotating component 815 is used to drive the rotating shaft 812 to rotate. A moving component 816 is arranged between the mold 3 and the two moving blocks 811, and the moving component 816 is used to synchronously drive the two moving blocks 811 to move toward or away from the side of the mold 3.

[0033] Before starting positioning, the moving block 811 and the arc-shaped positioning plate 813 are both received in the receiving groove 31 on the mold 3 and are integral with the mold 3. When it is necessary to position the plate-like profile, first, the moving component 816 synchronously drives the two moving blocks 811 to move away from the center of the mold 3 until the moving block 811 reaches the predetermined position. Then the rotating component 815 is started, driving the rotating shaft 812 to rotate, so that the arc-shaped positioning plate 813 rotates toward the outside of the receiving groove 31. Then the staff places the plate-like profile on the top of the mold 3, and at the same time, the positioning claws 814 on the arc-shaped positioning plates 813 on both sides of the plate-like profile clamp the plate-like profile. Then the moving component 816 synchronously drives the two moving blocks 811 to move closer to the center of the mold 3, so that the positioning claws 814 drive the plate-like profile to automatically align with the center of the mold 3, ensuring that it is accurately placed on the top of the arc, and then the fixing component 82 can fix the position of the plate-like profile. After the plate-like profile is fixed, the two moving blocks 811 are synchronously driven by the moving component 816 to move away from the center of the mold 3, so that the positioning jaws 814 separate the plate-like profile, and the rotating component 815 drives the rotating shaft 812 and the arc-shaped positioning plate 813 to rotate toward the side close to the receiving groove 31, and after the initial state is restored, the moving component 816 drives the moving block 811 and the arc-shaped positioning plate 813 to retract into the receiving groove 31, so that the mold 3 forms a complete whole, and the accurate positioning and fixing of the plate-like profile can be completed. Among them, through the precise control of the moving component 816 and the rotating component 815, the positioning component 81 can align the center of the plate-like profile, significantly improve the positioning accuracy of the plate-like profile, reduce the error of manual operation and the waste caused by inaccurate positioning, and improve the yield rate.

[0034] Reference Figure 5 and Figure 7 The moving part 816 includes two racks 8161 slidably connected to the mold 3, the two racks 8161 correspond to the two moving blocks 811 one by one, and the racks 8161 are fixedly connected to the corresponding moving blocks 811; illustratively, a dovetail block or a T-block is fixedly arranged on the mold 3 in the horizontal direction, and a dovetail groove or a T-slot matching the dovetail block or the T-block is provided on the side of the rack 8161 away from the teeth on the rack 8161. A driving motor 8162 is arranged in the mold 3, and a gear 8163 is fixedly arranged on the output shaft of the driving motor 8162, and the two racks 8161 are respectively located on both sides of the gear 8163 and mesh with the gear 8163.

[0035] When the moving block 811 needs to be moved, the driving motor 8162 is first started, and the gear 8163 on the output shaft of the driving motor 8162 starts to rotate. As the gear 8163 rotates, the two racks 8161 meshing with the gear 8163 move synchronously in the opposite direction. Since the racks 8161 are fixedly connected to the moving block 811, the moving block 811 moves synchronously therewith. The moving block 811 can move away from or close to the center of the mold 3 by the forward and reverse rotation of the driving motor 8162, so as to realize the deployment or retraction of the positioning assembly 81.

[0036] Reference Figure 5 and Figure 6 The rotating component 815 includes a worm wheel 8151 fixedly mounted on the rotating shaft 812, a worm 8152 is rotatably connected to the moving block 811, a rotating motor 8153 is disposed at one end of the worm 8152, and the worm wheel 8151 and the worm 8152 are meshed with each other.

[0037] When the arc-shaped positioning plate 813 needs to be rotated, the rotating motor 8153 is started, and the output shaft of the rotating motor 8153 drives the worm 8152 to start rotating. As the worm 8152 rotates, the worm wheel 8151 meshing with the worm 8152 starts to rotate, and the rotating shaft 812 rotates accordingly. The rotation of the rotating shaft 812 drives the arc-shaped positioning plate 813 to rotate out of the storage slot 31 or rotate toward one side of the storage slot 31, thereby realizing the expansion or retraction of the arc-shaped positioning plate 813.

[0038] Reference Figure 7 and Figure 8 The positioning clamp 814 includes a bracket 8141 fixed to one side of the arc-shaped positioning plate 813, a fixed claw 8142 is fixed to the bracket 8141, and a movable claw 8143 is slidably connected to the bracket 8141. A driving screw 8144 is rotatably connected to the bracket 8141, the driving screw 8144 is threadedly connected to the movable claw 8143, and a power motor 8145 is provided at one end of the driving screw 8144.

[0039] When it is necessary to clamp the plate, the power motor 8145 is started, and the output shaft of the power motor 8145 drives the driving screw 8144 to start rotating, and the movable claw 8143 threadedly connected to the driving screw 8144 starts to move in the vertical direction, approaching the fixed claw 8142, until it clamps the plate together with the fixed claw 8142, and the upper end surface of the fixed clamping claw is flush with the bottom of the plate, ensuring the stability of the plate during processing. By adjusting the rotation direction of the output shaft of the power motor 8145, the position of the movable claw 8143 can be flexibly controlled to meet the clamping requirements of plate-like plates of different thicknesses and sizes, thereby improving the flexibility and adaptability of the positioning component 81.

[0041] When the plate needs to be fixed, the vacuum pump device 6 is started, and at the same time the second electrically controlled valve is opened to connect the adsorption and fixing pipe 821 with the vacuum pump device 6. Negative pressure is generated inside the mold 3 through the adsorption and fixing pipe 821 to adsorb and fix the plate on the mold 3, thereby ensuring the stability of the plate during processing.

The plate-shaped profile is automatically aligned and positioned by the positioning assembly 81 to ensure that the plate-shaped profile is accurately placed on the top of the arc of the mold 3. The positioning jaws 814 drive the plate-shaped profile to automatically align the center of the mold 3 to ensure that it is accurately placed on the top of the arc, and then the rotating component 815 drives the rotating shaft 812 and the arc-shaped positioning plate 813 to rotate toward the side close to the receiving groove 31, and the positioning jaws 814 exert a downward force on the plate-shaped profile to make the plate-shaped profile abut against the top opening of the adsorption fixing pipe 821.

[0045] S3. The fixing assembly 82 utilizes the negative pressure of the vacuum pump device 6 to firmly adsorb the plate-shaped profile on the mold 3 to prevent it from shifting during the heating and molding process.

[0046] S4, after the plate-like profile is firmly fixed, the fixing frame 7 is rotated to make the flexible plastic film 71 cover the top of the plate-like profile, and the buckle cover 22 is closed.

[0047] S5, start the radio frequency heater 23 to heat the plate-shaped profile above the mold 3, and at the same time, the vacuum pump device 6 evacuates the space between the flexible molding film 71 and the supporting platform 21 through the negative pressure branch pipe 4 until the desired arc shape is formed.

[0048] S6, after the molding is completed, open the buckle cover 22 and safely remove the molded arc plate from the mold 3.

[0049] The positioning clamp 814 drives the plate-like profile to automatically align with the center of the mold 3 to ensure that it is accurately placed on the top of the arc. At this time, the plate-like profile is aligned with the top of the arc of the mold 3, but has not yet contacted the adsorption and fixing pipe 821. After the rotating component 815 drives the rotating shaft 812 and the arc-shaped positioning plate 813 to rotate toward the side close to the storage groove 31, the positioning clamp 814 applies a downward force to the plate-like profile, so that the plate-like profile abuts against the top opening of the adsorption and fixing pipe 821, and the plate-like profile can be firmly adsorbed by the adsorption and fixing pipe 821. Then the positioning clamp 814 releases the plate-like profile, and the rotating component 815 returns to the initial position.

[0050] The implementation principle of an arc plate manufacturing device and manufacturing process in an embodiment of the present application is as follows: through the cooperation of the positioning component 81 and the fixing component 82 in the positioning and fixing mechanism 8, the plate-like profile can be automatically positioned, calibrated and fixed relative to the center of the mold 3, so that when the staff covers the flexible plastic film 71, the plate-like profile is not easily displaced due to the external force of the flexible plastic film 71, thereby improving the positioning accuracy of the plate-like profile on the mold 3 and reducing the errors caused by manual visual inspection and experience-based adjustment. At the same time, the plate-like profile is also firmly fixed during the heating and forming process, thereby improving the stability of the arc plate in the production process and the quality of the finished product and reducing the scrap rate.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
