Description

Technical Field

[0001] This application relates to the field of arc plate processing technology, and in particular to an arc plate manufacturing device and manufacturing process. Background Technology

[0002] Radio frequency (RF) heating is a technology that uses electromagnetic waves with frequencies between 3kHz and 300MHz to heat materials. This heating method has many advantages: RF heating is very fast; the high-frequency alternating electromagnetic waves can rapidly cause the molecules in the material to move at high speeds, achieving a rapid heating effect. This heating method also features uniform heating from both inside and out, ensuring that the material is heated evenly and avoiding localized overheating or underheating.

[0003] Currently, with the increasing popularity of customized furniture, various specially shaped furniture pieces have emerged. Among them, the processing of door and wall cabinets requires the use of arc-shaped board making devices to press or bend wooden boards into arc-shaped boards with a certain curvature or angle. The arc-shaped board making device uses radio frequency heaters to heat and soften the wooden boards, making their internal fiber structure softer, which facilitates subsequent curing and molding. The arc-shaped board making device mainly includes a device body, a support platform fixed inside the device body, a mold set above the support platform, a cover set on the top of the device body, and multiple radio frequency heaters set on the cover. However, because the upper surface of the mold is arc-shaped, when placing the board-shaped profile, the board-shaped profile needs to be at the top of the arc of the mold. Its state is extremely unstable and easily shifted under external force. Moreover, the position of the board-shaped profile needs to be adjusted by the workers' visual inspection and experience, which not only results in low positioning accuracy but also makes positioning difficult and leads to a high scrap rate. Summary of the Invention

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

[0005] Firstly, the arc plate manufacturing device provided in this application adopts the following technical solution:

[0006] An arc plate manufacturing apparatus includes a frame, an apparatus body disposed on the frame, a support platform fixed inside the apparatus body, a mold disposed above the support platform, a cover disposed on the top of the apparatus body, and a plurality of radio frequency heaters disposed on the cover.

[0007] Negative pressure branch pipes are installed on the support platform, and multiple pipes are provided and connected to the interior of the molding chamber;

[0008] A negative pressure main pipeline is located between multiple negative pressure branch pipelines and is connected to all of the multiple negative pressure branch pipelines. A first electrically controlled valve is installed on the negative pressure main pipeline.

[0009] A vacuum pump device is mounted on the frame and connected to the negative pressure main pipeline;

[0010] A fixing frame is disposed between the buckle cover and the device body and is hinged to the device body;

[0011] A flexible molding film is disposed on the fixed frame and located above the mold;

[0012] A positioning and fixing mechanism is provided, comprising a positioning component and a fixing component; the positioning component is disposed on the mold and is used to automatically align and position the plate-shaped profile relative to the center of the mold; the fixing component is disposed between the mold and the vacuum pump device and is used to fix the aligned and positioned plate-shaped profile.

[0013] By adopting the above technical solution, when making an arc-shaped plate from a sheet profile, the sheet profile is first placed on top of the mold above the support platform. Then, the positioning component automatically aligns and positions the sheet profile to ensure it is accurately placed on the top of the arc of the mold. Subsequently, the fixing component uses the negative pressure of the vacuum pump to firmly adhere the sheet profile to the mold, preventing it from shifting during heating and forming. After the sheet profile is firmly fixed, the operator rotates the fixing frame to cover the sheet profile with a flexible molding film. Then, the cover is closed, and the radio frequency heater is activated to heat the sheet profile above the mold. The high-frequency electromagnetic waves from the radio frequency heating cause the molecules inside the wood to move at high speed, rapidly softening the fiber structure of the wood. At the same time, the vacuum pump device creates a vacuum between the flexible molding film and the support platform through a negative pressure branch pipe. As the radio frequency heater and negative pressure are applied, the plate-shaped profile gradually softens and begins to conform to the arc shape of the mold. The plate-shaped profile gradually solidifies, eventually forming the desired arc shape. After molding, the operator opens the cover and safely removes the formed arc plate from the mold. Through the cooperation of the positioning and fixing components in the positioning and fixing mechanism, the plate-shaped profile can be automatically positioned, calibrated, and fixed relative to the center of the mold. This prevents the plate-shaped profile from shifting due to the external force of the flexible molding film when the operator covers it, improving the positioning accuracy of the plate-shaped profile on the mold and reducing errors from manual visual inspection and experience adjustment. At the same time, the plate-shaped profile is also firmly fixed during heating and molding, improving the stability of the arc plate in the production process and the quality of the finished product, and reducing the scrap rate.

[0014] Optionally, the positioning component includes:

[0015] Two movable blocks are provided, with the two movable blocks located on opposite sides of the mold, and each movable block is rotatably connected to a rotating shaft;

[0016] An arc-shaped positioning plate is fixed to the rotating shaft, and the arc-shaped positioning plates on the two rotating shafts are symmetrically arranged. The mold is provided with a storage groove, and the arc-shaped positioning plate can be rotated and stored in the storage groove.

[0017] The positioning gripper is located at the end of the arc-shaped positioning plate away from the rotation axis, and on the side of the arc-shaped positioning plate closer to the mold;

[0018] A rotating component is disposed between the movable block and the rotating shaft, and is used to drive the rotating shaft to rotate.

[0019] A movable component is disposed between the mold and the two movable blocks, and is used to synchronously drive the two movable blocks to move toward or away from the mold.

[0020] By adopting the above technical solution, before positioning begins, both the moving blocks and the arc-shaped positioning plate are stored in the receiving slots on the mold, forming a single unit with the mold. When positioning of the sheet profile is required, the moving component first synchronously moves the two moving blocks away from the mold center until the moving blocks reach the predetermined position. Then, the rotating component is activated, driving the rotating shaft to rotate, causing the arc-shaped positioning plate to rotate outward from the receiving slot. Subsequently, the operator places the sheet profile on the top of the mold, and the positioning claws on the arc-shaped positioning plates on both sides of the sheet profile clamp the sheet profile. Then, the moving component synchronously moves the two moving blocks closer to the mold center, causing the positioning claws to automatically align the sheet profile with the center of the mold, ensuring its precise placement on the arc-shaped top. Then, the fixing component can fix the position of the plate-shaped profile. After the plate-shaped profile is fixed, the moving component synchronously drives the two moving blocks to move away from the center of the mold, so that the positioning claws separate the plate-shaped profile. Then, the rotating component drives the rotating shaft and the arc-shaped positioning plate to rotate towards the receiving groove. After returning to the initial state, the moving component drives the moving blocks and the arc-shaped positioning plate to retract into the receiving groove, so that the mold forms a complete whole, thus completing the precise positioning and fixing of the plate-shaped profile. In particular, through the precise control of the moving component and the rotating component, the positioning component can center-align the plate-shaped profile, significantly improving the positioning accuracy of the plate-shaped profile, reducing the error of manual operation and the scrap caused by inaccurate positioning, and improving the yield.

[0021] Optionally, the moving component includes two racks slidably connected to the mold, a drive motor disposed inside the mold, and a gear fixed to the output shaft of the drive motor;

[0022] The two racks correspond one-to-one with the two moving blocks, and the racks are fixedly connected to the corresponding moving blocks. The two racks are located on both sides of the gear and mesh with the gear.

[0023] By adopting the above technical solution, when the moving block needs to be moved, the drive motor is first started, and the gear on the output shaft of the drive motor begins to rotate. As the gear rotates, the two racks meshing with the gear move synchronously in opposite directions. Since the racks are fixedly connected to the moving block, the moving block moves synchronously as well. In this way, by rotating the drive motor in both directions, the moving block can move away from or towards the center of the mold, thereby realizing the unfolding or retraction of the positioning component.

[0024] Optionally, the rotating component includes a worm gear fixedly sleeved on the rotating shaft, a worm rotatably connected to the moving block, and a rotary motor disposed at one end of the worm; the worm gear and the worm mesh with each other.

[0025] By adopting the above technical solution, when the arc-shaped positioning plate needs to be rotated, the rotary motor starts, and the output shaft of the rotary motor drives the worm to start rotating. As the worm rotates, the worm wheel meshing with the worm starts to rotate, and the rotating shaft rotates accordingly. The rotation of the rotating shaft will drive the arc-shaped positioning plate to rotate out of the storage slot or rotate to one side of the storage slot, so as to realize the unfolding or retraction of the arc-shaped positioning plate.

[0026] Optionally, the positioning gripper includes a bracket fixed to one side of the arc-shaped positioning plate, a fixed gripper fixed to the bracket, a movable gripper slidably connected to the bracket, a drive screw rotatably connected to the bracket, and a power motor disposed at one end of the drive screw; the drive screw is threadedly connected to the movable gripper.

[0027] By adopting the above technical solution, when it is necessary to clamp the plate, the power motor is started, and the output shaft of the power motor drives the drive screw to start rotating. The movable claw, which is threadedly connected to the drive screw, begins to move vertically and approaches the fixed claw until it clamps the plate together with the fixed claw. The upper end face of the fixed claw is flush with the bottom of the plate, ensuring the stability of the plate during processing. By adjusting the rotation direction of the power motor output shaft, the position of the movable claw can be flexibly controlled, thereby adapting to the clamping requirements of plate-shaped plates of different thicknesses and improving the flexibility and adaptability of the positioning component.

[0028] Optionally, the fixing component includes a plurality of adsorption fixing pipes fixed inside the mold and a second electrically controlled valve disposed on the adsorption fixing pipes. The plurality of adsorption fixing pipes are arranged along the length direction of the mold and are located in the middle position of the mold. The adsorption fixing pipes are connected to the vacuum pump device.

[0029] By adopting the above technical solution, when it is necessary to fix the board, the vacuum pump device is started and the second electrically controlled valve is opened to connect the adsorption fixing pipe to the vacuum pump device. The adsorption fixing pipe generates negative pressure inside the mold, adsorbing and fixing the board onto the mold, thus ensuring the stability of the board during the processing.

[0030] Optionally, a positioning block is fixed on the support platform, and a positioning hole is opened on the mold, into which the positioning block is inserted.

[0031] By adopting the above technical solution, when it is necessary to replace the mold, the new mold is placed on the support platform, the positioning hole on the mold is aligned with the positioning block on the support platform, and the mold is gently pressed down, so that the positioning block can be accurately inserted into the positioning hole, realizing the rapid positioning and fixing of the mold; the positioning block and the positioning hole ensure the stable position of the mold on the support platform and avoid the deviation during the processing.

[0032] Optionally, a gas spring is provided between the fixing frame and the device body.

[0033] By adopting the above technical solution, the gas spring provides support between the fixed frame and the device body, balances the weight of the fixed frame, and makes the fixed frame more stable when opening and closing, reducing shaking and impact during operation.

[0034] Secondly, the arc plate manufacturing process provided in this application is applicable to one of the aforementioned arc plate manufacturing devices, and its manufacturing steps are as follows:

[0035] S1. Place the plate-shaped profile on the top of the mold above the support platform;

[0036] S2. The positioning component automatically aligns and positions the plate-shaped profile to the center, ensuring that the plate-shaped profile is accurately placed on the arc top of the mold;

[0037] S3. The fixing component uses the negative pressure of the vacuum pump device to firmly adsorb the plate-shaped profile onto the mold, preventing it from shifting during heating and molding.

[0038] S4. After the plate-shaped profile is firmly fixed, rotate the fixing frame so that the flexible plastic film covers the top of the plate-shaped profile, and close the buckle.

[0039] S5. Start the radio frequency heater to heat the plate-shaped profile above the mold, and at the same time, the vacuum pump device evacuates the flexible molding film and the support platform through the negative pressure branch pipe until the plate-shaped profile forms the required arc shape.

[0040] S6. After the molding is completed, open the cover and safely remove the formed arc-shaped plate profile from the mold.

[0041] Optionally, in S2, the positioning gripper drives the plate-shaped profile to automatically align with the center of the mold, ensuring that it is accurately placed on the arc-shaped top of the plate-shaped profile. Then, the rotating component drives the rotating shaft and the arc-shaped positioning plate to rotate towards the side closer to the storage groove. The positioning gripper applies a downward force to the plate-shaped profile, causing the plate-shaped profile to abut against the top opening of the adsorption fixing pipe.

[0042] By adopting the above technical solution, the positioning gripper drives the plate-shaped profile to automatically align with the center of the mold, ensuring that it is accurately placed on the top of the arc. At this time, the plate-shaped profile is aligned with the top of the arc of the mold, but has not yet come into contact with the adsorption and fixing pipe. After the rotating component drives the rotating shaft and the arc-shaped positioning plate to rotate towards the side closer to the receiving groove, the positioning gripper applies a downward force to the plate-shaped profile, so that the plate-shaped profile abuts against the top opening of the adsorption and fixing pipe. The plate-shaped profile can then be firmly adsorbed by the adsorption and fixing pipe. Afterward, the positioning gripper releases the plate-shaped profile, and the rotating component returns to the initial position.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] 1. Through the cooperation of the positioning and fixing components in the positioning and fixing mechanism, the plate profile can be automatically positioned, calibrated and fixed relative to the center of the mold. This prevents the plate profile from shifting due to the external force of the flexible molding film when the operator covers it, thus improving the positioning accuracy of the plate profile on the mold and reducing errors from manual visual inspection and experience adjustment. At the same time, the plate profile is also firmly fixed during heating and forming, which improves the stability of the arc plate in the production process and the quality of the finished product, and reduces the scrap rate.

[0045] 2. Through precise control of the moving and rotating parts in the positioning assembly, the positioning assembly can center-align the plate profile, significantly improving the positioning accuracy of the plate profile, reducing errors from manual operation and scrap caused by inaccurate positioning, and increasing the yield rate;

[0046] 3. By adjusting the rotation direction of the output shaft of the power motor in the positioning gripper, the position of the movable gripper can be flexibly controlled, thereby adapting to the clamping requirements of plate-shaped materials of different thicknesses and improving the flexibility and adaptability of the positioning component;

[0047] 4. The positioning gripper automatically aligns the plate-shaped profile with the center of the mold, ensuring its precise placement on the top of the arc. At this point, the plate-shaped profile is aligned with the top of the arc of the mold, but has not yet come into contact with the adsorption and fixing pipe. The rotating component drives the rotating shaft and the arc-shaped positioning plate to rotate towards the side closer to the receiving slot. The positioning gripper then applies a downward force to the plate-shaped profile, causing it to abut against the top opening of the adsorption and fixing pipe. The plate-shaped profile is then firmly adsorbed by the adsorption and fixing pipe. Subsequently, the positioning gripper releases the plate-shaped profile, and the rotating component returns to its initial position. Attached Figure Description

[0057] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0058] This application discloses an apparatus for manufacturing an arc-shaped plate. (Refer to...) Figures 1-4 The arc plate manufacturing device includes a frame 1, on which a device body 2 is mounted. A support platform 21 is fixed inside the device body 2. A mold 3 is mounted above the support platform 21. A cover 22 is mounted on the top of the device body 2, and multiple radio frequency heaters 23 are mounted on the cover 22. Multiple negative pressure branch pipes 4 are mounted on the support platform 21, communicating with the interior of the molding chamber. A main negative pressure pipe 5 is connected between the multiple negative pressure branch pipes 4, and the main negative pressure pipe 5 is connected to all the multiple negative pressure branch pipes 4. A first electrically controlled valve is also mounted on the main negative pressure pipe 5. A vacuum pump device 6 is mounted on the frame 1 and connected to the main negative pressure pipe 5. A fixing frame 7 is mounted between the cover 22 and the device body 2, and is hinged to the device body 2. A flexible molding film 71 is mounted on the fixing frame 7, and is located above the mold 3. The flexible molding film 71 is made of silicone. A gas spring 72 is provided between the fixed frame 7 and the device body 2. The gas spring 72 provides support between the fixed frame 7 and the device body 2, balances the weight of the fixed frame 7, and makes the fixed frame 7 more stable when opening and closing, reducing shaking and impact during operation.

[0059] 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. The positioning component 81 is disposed on the mold 3 and is used to automatically align and position the plate-shaped profile relative to the center of the mold 3. The fixing component 82 is disposed between the mold 3 and the vacuum pump device 6 and is used to fix the aligned and positioned plate-shaped profile.

[0060] When making an arc-shaped panel using sheet-like profiles, the sheet-like profile is first placed on top of the mold 3 above the support platform 21. Then, the positioning component 81 automatically aligns and positions the sheet-like profile to ensure it is accurately placed on the arc-shaped top of the mold 3. Subsequently, the fixing component 82 uses the negative pressure of the vacuum pump device 6 to firmly adhere the sheet-like profile to the mold 3, preventing it from shifting during heating and molding. After the sheet-like profile is firmly fixed, the operator rotates the fixing frame 7 to cover the sheet-like profile with the flexible molding film 71. Then, the cover 22 is closed, and the radio frequency heater 23 is activated to heat the sheet-like profile above the mold 3. The high-frequency electromagnetic waves from the radio frequency heating cause the molecules inside the wood to move at high speed, rapidly softening the fiber structure of the wood.

[0061] Simultaneously, the vacuum pump device 6 creates a vacuum between the flexible molding film 71 and the support platform 21 through the negative pressure branch pipe 4. Under the action of the radio frequency heater 23 and the negative pressure, the plate-shaped profile gradually softens and begins to conform to the arc shape of the mold 3. The plate-shaped profile gradually solidifies, ultimately forming the desired arc shape. After molding, the operator opens the cover 22 and safely removes the formed arc plate from the mold 3. The positioning and fixing mechanism 8, through the cooperation of the positioning component 81 and the fixing component 82, automatically positions and fixes the plate-shaped profile relative to the center of the mold 3. This prevents the plate-shaped profile from shifting due to the external force of the flexible molding film 71 when it is covered, improving the positioning accuracy of the plate-shaped profile on the mold 3 and reducing errors from manual visual inspection and experience-based adjustments. Furthermore, the plate-shaped profile is firmly fixed during heating and molding, improving the stability of the arc plate during production and the quality of the finished product, thus reducing the scrap rate.

[0062] Reference Figure 5 and Figure 6 The positioning component 81 includes two movable blocks 811 respectively disposed on both sides of the mold 3 in the width direction, and each movable block 811 is rotatably connected to a rotating shaft 812. An arc-shaped positioning plate 813 is fixedly mounted on the rotating shaft 812, and the arc-shaped positioning plates 813 on the two rotating shafts 812 are symmetrically arranged. A receiving groove 31 is provided on the mold 3, and the arc-shaped positioning plate 813 can be rotatably stored in the receiving groove 31. A positioning gripper 814 is provided at the end of the arc-shaped positioning plate 813 away from the rotating shaft 812, and the positioning gripper 814 is located on the side of the arc-shaped positioning plate 813 closer to the mold 3. A rotating component 815 is disposed between the movable block 811 and the rotating shaft 812, and the rotating component 815 is used to drive the rotating shaft 812 to rotate. A movable component 816 is disposed between the mold 3 and the two movable blocks 811, and the movable component 816 is used to synchronously drive the two movable blocks 811 to move towards or away from the mold 3.

[0063] Before positioning begins, the moving block 811 and the arc-shaped positioning plate 813 are both stored in the storage slot 31 on the mold 3, forming a single unit with the mold 3. When positioning the sheet profile is required, the moving component 816 first moves the two moving blocks 811 away from the center of the mold 3 until the moving blocks 811 reach the predetermined position. Then, the rotating component 815 is activated, driving the rotating shaft 812 to rotate, causing the arc-shaped positioning plate 813 to rotate outward from the storage slot 31. Subsequently, the operator places the sheet profile on the top of the mold 3, and the positioning claws 814 on the arc-shaped positioning plates 813 on both sides of the sheet profile clamp the sheet profile. Then, the moving component 816 moves the two moving blocks 811 closer to the center of the mold 3, causing the positioning claws 814 to automatically align the sheet profile with the center of the mold 3, ensuring that it is accurately placed on the arc-shaped top. Finally, the fixing component 82 fixes the position of the sheet profile. After the sheet-like profile is fixed, the moving component 816 synchronously moves the two moving blocks 811 away from the center of the mold 3, causing the positioning gripper 814 to separate from the sheet-like profile. Then, the rotating component 815 drives the rotating shaft 812 and the arc-shaped positioning plate 813 to rotate towards the receiving groove 31. After returning to the initial state, the moving component 816 drives the moving blocks 811 and the arc-shaped positioning plate 813 to retract into the receiving groove 31, making the mold 3 a complete whole, thus completing the precise positioning and fixing of the sheet-like profile. Through the precise control of the moving component 816 and the rotating component 815, the positioning component 81 can center-align the sheet-like profile, significantly improving the positioning accuracy of the sheet-like profile, reducing errors from manual operation and scrap caused by inaccurate positioning, and increasing the yield.

[0064] Reference Figure 5 and Figure 7 The moving component 816 includes two racks 8161 slidably connected to the mold 3. Each rack 8161 corresponds to one of the two moving blocks 811, and the racks 8161 are fixedly connected to their respective moving blocks 811. For example, a dovetail block or a T-shaped block is fixedly provided on the mold 3 in the horizontal direction. A dovetail groove or T-shaped groove adapted to the dovetail block or T-shaped block is provided on the toothed side of the rack 8161. A drive motor 8162 is provided inside the mold 3. A gear 8163 is fixedly provided on the output shaft of the drive motor 8162. The two racks 8161 are located on both sides of the gear 8163 and mesh with it.

[0065] When the moving block 811 needs to be moved, the drive motor 8162 is started first, and the gear 8163 on the output shaft of the drive motor 8162 begins to rotate. As the gear 8163 rotates, the two racks 8161 meshing with the gear 8163 move synchronously in opposite directions. Since the racks 8161 are fixedly connected to the moving block 811, the moving block 811 moves synchronously accordingly. By rotating the drive motor 8162 in both directions, the moving block 811 can move away from or towards the center of the mold 3, thus enabling the positioning component 81 to unfold or retract.

[0066] Reference Figure 5 and Figure 6 The rotating component 815 includes a worm gear 8151 fixedly sleeved on the rotating shaft 812, a worm 8152 rotatably connected to the moving block 811, a rotary motor 8153 provided at one end of the worm 8152, and the worm gear 8151 and the worm 8152 meshing with each other.

[0067] When the arc-shaped positioning plate 813 needs to be rotated, the rotary motor 8153 starts, and the output shaft of the rotary motor 8153 drives the worm gear 8152 to start rotating. As the worm gear 8152 rotates, the worm wheel 8151 meshing with the worm gear 8152 starts to rotate, and at the same time the rotating shaft 812 rotates accordingly. The rotation of the rotating shaft 812 will drive the arc-shaped positioning plate 813 to rotate out of the storage groove 31 or rotate to one side of the storage groove 31, so as to realize the unfolding or retraction of the arc-shaped positioning plate 813.

[0068] Reference Figure 7 and Figure 8 The positioning gripper 814 includes a bracket 8141 fixed to one side of the arc-shaped positioning plate 813. A fixed gripper 8142 is fixed on the bracket 8141, and a movable gripper 8143 is slidably connected to the bracket 8141. A drive screw 8144 is rotatably connected to the bracket 8141. The drive screw 8144 is threadedly connected to the movable gripper 8143, and a power motor 8145 is provided at one end of the drive screw 8144.

[0069] When clamping the sheet metal is required, the power motor 8145 is started. The output shaft of the power motor 8145 drives the drive screw 8144 to rotate. The movable jaw 8143, which is threadedly connected to the drive screw 8144, begins to move vertically, approaching the fixed jaw 8142, until they clamp the sheet metal together. The upper surface of the fixed jaw is flush with the bottom of the sheet metal, ensuring the stability of the sheet metal during processing. By adjusting the rotation direction of the output shaft of the power motor 8145, the position of the movable jaw 8143 can be flexibly controlled, thereby adapting to the clamping requirements of sheet metal of different thicknesses and improving the flexibility and adaptability of the positioning assembly 81.

[0070] Reference Figure 5 and Figure 7The fixing component 82 includes multiple adsorption fixing pipes 821 fixed inside the mold 3. The multiple adsorption fixing pipes 821 are arranged along the length of the mold 3 and are located in the middle of the mold 3. The adsorption fixing pipes 821 are connected to the vacuum pump device 6. A second electrically controlled valve is also provided on the adsorption fixing pipes 821.

[0071] When it is necessary to fix the board, start the vacuum pump device 6, and at the same time open the second electrically controlled valve to connect the adsorption fixing pipe 821 with the vacuum pump device 6. The adsorption fixing pipe 821 generates negative pressure inside the mold 3, adsorbing and fixing the board onto the mold 3, thus ensuring the stability of the board during the processing.

[0072] Reference Figure 7 At least two positioning blocks 9 are fixed on the support platform 21, and positioning holes are opened on the mold 3. The positioning blocks 9 are inserted into the positioning holes. The positioning blocks 9 and the positioning holes ensure the stable position of the mold 3 on the support platform 21 and avoid deviation during the processing.

[0073] This application also discloses a process for manufacturing an arc plate, applicable to the aforementioned arc plate manufacturing apparatus, the manufacturing steps of which are as follows:

[0074] S1. Place the plate-shaped profile on top of the mold 3 above the support platform 21.

[0075] S2. The positioning component 81 automatically aligns and positions the plate-shaped profile to ensure that it is accurately placed on the arc-shaped top of the mold 3. The positioning gripper 814 drives the plate-shaped profile to automatically align with the center of the mold 3, ensuring that it is accurately placed on the arc-shaped top. Then, the rotating component 815 drives the rotating shaft 812 and the arc-shaped positioning plate 813 to rotate towards the side closer to the receiving groove 31. The positioning gripper 814 applies a downward force to the plate-shaped profile, so that the plate-shaped profile abuts against the top opening of the adsorption fixing pipe 821.

[0076] S3. Fixing component 82 uses the negative pressure of vacuum pump device 6 to firmly adsorb the plate-shaped profile onto mold 3, preventing it from shifting during heating and molding.

[0077] S4. After the plate-shaped profile is firmly fixed, rotate the fixing frame 7 so that the flexible plastic film 71 covers the top of the plate-shaped profile and close the buckle 22.

[0078] S5. Start the radio frequency heater 23 to heat the plate-shaped profile above the mold 3. At the same time, the vacuum pump device 6 evacuates the flexible plastic film 71 and the support platform 21 through the negative pressure branch pipe 4 until the required arc shape is formed.

[0079] S6. After the molding is completed, open the cover 22 and safely remove the formed arc plate from the mold 3.

[0080] The positioning gripper 814 automatically aligns the plate-shaped profile with the center of the mold 3, ensuring that it is accurately placed on the top of the arc. At this time, the plate-shaped profile is aligned with the top of the arc of the mold 3, but has not yet come into contact with 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 towards the side closer to the storage groove 31, the positioning gripper 814 applies a downward force to the plate-shaped profile, so that the plate-shaped profile abuts against the top opening of the adsorption and fixing pipe 821. The plate-shaped profile can then be firmly adsorbed by the adsorption and fixing pipe 821. Afterward, the positioning gripper 814 releases the plate-shaped profile, and the rotating component 815 returns to the initial position.

[0081] The implementation principle of the arc plate manufacturing device and manufacturing process in this application embodiment 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-shaped profile can be automatically positioned, calibrated and fixed relative to the center of the mold 3. When the operator covers the flexible plastic film 71, the plate-shaped profile is not easily displaced due to the external force of the flexible plastic film 71, which improves the positioning accuracy of the plate-shaped profile on the mold 3, reduces the error of manual visual inspection and experience adjustment, and at the same time, the plate-shaped profile is also firmly fixed during the heating and forming 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.

[0082] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
