Description

Technical Field

[0001] This utility model relates to the field of radio frequency machine technology, specifically to a radio frequency machine for product processing and forming. Background Technology

[0002] During the product manufacturing process, a series of complex operations are frequently encountered, including but not limited to lamination, adhesive bonding, edge bending, and arc forming. Each of these operations requires specific equipment. For example, lamination typically relies on a cold press, adhesive bonding requires a hot press, edge bending is achieved using a specialized folding machine, and arc forming requires an arc forming machine. While these machines are powerful, their production costs are relatively high, and they can only perform single-function forming operations, making it impossible to comprehensively handle all the forming operations involved in door panel production.

[0003] Furthermore, if arc forming is required after adhesive bonding, the adhesive bonding process is usually completed first in a hot press, and then the product is transferred to an arc forming machine for further processing. This transfer process typically requires time for the product to cool and dry, resulting in a lengthy process. Therefore, a product processing and forming equipment that integrates multiple operations such as pressing, bonding, edge bending, and arc forming is needed to reduce overall production equipment costs and improve production efficiency.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] An RF machine for product processing and molding, such as Figures 1 to 9 As shown, the system includes an RF heating chamber 1, a vacuum chamber 2, a silicone membrane sealing frame 3, and a control system 4. The silicone membrane sealing frame 3 is disposed between the RF heating chamber 1 and the vacuum chamber 2. The RF heating chamber 1 is hinged to the vacuum chamber 2 via a first hinge, and one side of the silicone membrane sealing frame 3 is hinged to the vacuum chamber 2 via a second hinge. The vacuum chamber 2 is provided with a first drive module for driving the RF heating chamber 1 to rotate and a second drive module for driving the silicone membrane sealing frame 3 to rotate. The control system 4 is disposed on the vacuum chamber 2, and the controlled ends of the RF heating chamber 1, the vacuum chamber 2, the first drive module, and the second drive module are respectively connected to the output end of the control system 4.

[0031] The bottom of the vacuum chamber 2 is also provided with casters 5. In this embodiment, there are 6 casters 5. In other embodiments, the number of casters 5 can be set as needed, which can drive the radio frequency equipment to move as a whole.

[0032] The radio frequency heating box 1 includes a main frame 100, and an inner box plate 101 is provided inside the main frame 100. The top of the inner box plate 101 is an isosceles trapezoidal structure. Magnetrons 104 are evenly arranged on the top surface and two isosceles side surfaces of the top of the inner box plate. The controlled end of the magnetron 104 is connected to the output end of the control system 4.

[0033] The top of the inner panel 101 is also equipped with a control power module 107, which is used to supply power to the entire device.

[0034] A fan is installed on one side of the magnetron 104. The fan is connected to the magnetron 104 through a duct, which can cool the magnetron 104 in a timely manner.

[0035] The main frame 100 of the radio frequency heating box is provided with an outer box plate 102. A top plate 103 is provided on the top of the outer box plate 102. An axial flow fan 105 is provided in the middle of the top plate 103. The controlled end of the axial flow fan 105 is connected to the output end of the control system 4.

[0036] Ventilation holes are provided on both sides of the top plate 103, which, in conjunction with the axial flow fan 105, ensure heat dissipation inside the equipment and promote internal gas circulation.

[0037] The main frame 100 of the radio frequency heating box has a bottom aluminum profile frame 106 at the bottom. The bottom of the bottom aluminum profile frame 106 has an upper radio frequency sealing strip 108 for sealing, which is used to cooperate with the silicone film sealing frame 3 to ensure the airtightness of the radio frequency heating box 1.

[0038] The vacuum chamber 2 includes a vacuum chamber main frame 200. A downwardly recessed vacuum suction basin 203 is installed on the top of the vacuum chamber main frame 200. The bottom of the vacuum suction basin 203 is connected to the vacuum tank 208 through a steel wire hose. A vacuum pump is installed between the inlet of the steel wire hose and the outlet of the vacuum tank 208. The controlled end of the vacuum pump is connected to the output end of the control system.

[0039] The front panel 201 and the rear panel 202 are respectively installed on the front and rear sides of the main frame 200 of the vacuum chamber, and side protective plates 204 are respectively provided on the left and right sides of the main frame 200 of the vacuum chamber.

[0040] The top surface of the main frame 200 of the vacuum chamber is provided with a top aluminum profile frame 205 that presses the side of the vacuum suction basin 203 together. A vacuum sealing strip 206 is provided between the top aluminum profile frame 205 and the top surface of the vacuum suction basin 203 to ensure the airtightness of the vacuum chamber.

[0041] A lower radio frequency sealing strip 207 is provided on the top surface of the top aluminum profile frame 205 to cooperate with the silicone film sealing frame 3 to ensure a seal.

[0042] The vacuum suction cup 203 has a detachable molding die for processing and shaping the product. The molding die is positioned with the molding surface facing upward so that it can be quickly formed during the pressing process.

[0043] The forming mold can be selectively set according to the specific operation. For example, when folding, a forming mold that matches the folding shape can be placed in the vacuum suction cup 203, or when forming an arc, an arc-shaped forming mold can be placed in the vacuum suction cup. Then, the product to be formed is placed on the mold, and the product is formed by the cooperation of the vacuum box, silicone film sealing frame, and radio frequency heating box. If the forming mold is not required, the product can be placed directly in the vacuum suction cup, and the product can be processed by the cooperation of the vacuum box, silicone film sealing frame, and radio frequency heating box.

[0044] The silicone film sealing frame 3 includes a middle frame 300, and a silicone film 301 is installed inside the middle frame 300. The silicone film 301 is used to apply pressure to the product in conjunction with the vacuum chamber to ensure the product molding effect.

[0045] Specifically, a vertical plate 302 is provided on the inner side of the intermediate frame 300 to press the silicone membrane 301. The vertical plate 302 is connected to the intermediate frame 300 by a U-shaped clip 303, which can not only ensure the stability of the connection between the silicone membrane and the intermediate frame, but also prevent the silicone membrane from being damaged, affecting the pressing effect of the silicone membrane and the sealing of the equipment.

[0046] Specifically, one of the claws on the U-shaped card 303 is attached to the vertical plate 302, and the other claw on the U-shaped card 303 is attached to the outside of the middle frame 300. The horizontal part connecting the two claws is set on the top surface of the middle frame 300.

[0047] The side of the U-shaped card 303 away from the silicone film 301 is threadedly connected to the corresponding side of the intermediate frame 300 by bolts 304, which is used to lock the vertical plate 302, silicone film 301 and intermediate frame 300.

[0048] The first drive module includes a tilting arm 6 installed on the rear side of the main frame 100 of the radio frequency heating box. The other end of the tilting arm 6 is hinged to the piston rod 9 of the hydraulic cylinder 10. The main frame 200 of the vacuum box is provided with a hydraulic cylinder hinge seat 15 for mounting the hydraulic cylinder 10. The controlled end of the hydraulic cylinder 10 is connected to the output end of the control system 4.

[0049] The hydraulic cylinder 10 drives the tilting arm 6 to move, and with the cooperation of the first hinge, the radio frequency heating box 1 is tilted. The first hinge includes a7 and b8. The first hinge a7 is located on the top side of the main frame 200 of the vacuum box, and the first hinge b8 is located on the bottom side of the main frame 100 of the radio frequency heating box. The first hinge a7 and the first hinge b8 are hinged together by a hinge shaft.

[0050] A magnetic ring is installed on the piston rod 9 of the hydraulic cylinder, and a Hall sensor is installed on the main frame 200 of the vacuum box. The controlled end of the Hall sensor is connected to the output end of the control system to detect the change in magnetic field strength during the movement of the piston rod, and then convert it into a displacement signal and send it to the control system 4.

[0051] Specifically, taking the initial position of the RF heating box cover on the vacuum box as the initial position, the displacement signal is zero at this time. After the product is placed in the vacuum box, the piston rod in the hydraulic cylinder moves. When the RF heating box 1 is covered on the vacuum box 2 again under the action of the hydraulic cylinder and the tilting arm, it indicates that the RF machine is now completely sealed and the vacuuming and heating operations can begin.

[0052] The second drive module includes cylinders 11 installed on the left and right sides of the middle frame 300 respectively. The bottom of the vacuum box main frame 200 is provided with a cylinder hinge seat 12 for installing the cylinders 11. The movable end of the cylinder 11 is hinged to the side wall of the middle frame 300.

[0053] The silicone film sealing frame 2 can be flipped by the cooperation of cylinder 11 and the second hinge, which facilitates the placement of workpieces. The second hinge includes a second hinge a13 and a second hinge b14. The second hinge a13 is located on the top side of the main frame 200 of the vacuum chamber, and the second hinge b14 is located on the side of the middle frame 300. The second hinge a13 and the second hinge b14 are hinged together by a hinge shaft.

[0054] The number of first and second hinges can be set as needed, with the first and second hinges set at different intervals.

[0055] In use, firstly, the first and second drive modules control the RF heating box 1 and the silicone film sealing frame 3 to flip upwards, opening the vacuum box 2 and placing the product into the vacuum suction basin 203. Then, the RF heating box 1 and the silicone sealing frame 3 are flipped downwards, so that the product is in the closed inner cavity, and the equipment is sealed with the cooperation of the upper and lower RF sealing strips.

[0056] If it is necessary to place the product into a molding mold, the product should be placed into the molding mold first, then placed on the molding mold, and then sealed.

[0057] The molding die weighs around 100kg, which is within the controllable range of manual operation. The replacement of the molding die is relatively convenient and quick. Moreover, the production cost of the molding die is around 4,000 yuan, which is relatively low compared to various processing equipment with single functions.

[0058] Then, the vacuum pump is controlled to evacuate the inside of the vacuum chamber 2, causing the silicone film 301 to adhere to the product surface. Then, the magnetron 104 in the radio frequency heating chamber 1 heats the product by radio frequency. The vacuum chamber applies pressure to the product by adsorbing the silicone film onto the product surface. Through the cooperation of the vacuum chamber, the radio frequency heating chamber, and the silicone film sealing frame, the vacuuming and heating operations are completed in sequence to achieve the product processing and shaping.

[0059] By using a vacuum chamber and silicone film to press and mold products, the traditional cold press is replaced, which greatly improves the pressing efficiency. For example, when pressing wooden doors, it only takes 3 minutes to complete. Moreover, due to the use of radio frequency heating instead of the traditional hot press, the heating efficiency is significantly improved. When processing arcs, the hot pressing time of the arc is generally no more than 20 minutes, and its forming speed is twice that of the high frequency press.

[0060] This invention can not only perform pressing and folding operations, but also simultaneously perform pressing and arc forming or pressing and folding operations during the molding process. Simply place the molding mold in the vacuum suction cup, and the product can be molded in one step without switching equipment. This eliminates the intermediate cooling time when the product is switched between multiple devices, thus improving the quality and efficiency of product processing.

[0061] This utility model provides an RF machine for product processing and molding. Through the cooperation of an RF heating box, a silicone film sealing frame, a vacuum box, and a molding die arranged from top to bottom, it can integrate operations such as door panel pressing, wooden door bonding, edge folding, and arc forming, realizing integrated operation of product processing and molding. The RF heating box, silicone film sealing frame, vacuum box, and molding die adopt a modular design, which further reduces the production cost of product molding equipment.

[0062] Simultaneously, the control system enables automated control of operations such as product vacuuming, heating, and equipment start-up and shutdown, reducing manual operation and allowing for precise control of the vacuum level and radio frequency heating temperature, significantly improving the efficiency and quality of product processing and forming.

[0063] Moreover, when using molding molds for arc forming or curved surface processing, the product is heated by radio frequency heating and pressed with a silicone film, allowing the product to be adapted to the molding mold for faster forming. This increases the efficiency of curved surface processing by 200%, and the entire composite process cycle is ≤20 minutes. The processing efficiency is significantly improved, the entire production period can be shortened by about 30%, and the processing quality is stable and controllable.

[0064] In addition, the radio frequency heating box uses radio frequency microwave heating, which has a heating efficiency far exceeding that of ordinary heating methods, such as infrared heating. Furthermore, sealing strips are installed between the silicone film sealing frame and the radio frequency heating box and the vacuum box to ensure the sealing of the product during the molding process, avoiding radio frequency leakage during heating and air mixing during vacuuming. This fully utilizes the energy in the product processing and molding process and improves the production efficiency of the equipment.

[0065] This utility model, through its integrated design, is particularly suitable for flexible production scenarios such as customized wooden doors and bentwood furniture. It can also process other products that require pressing or curved surface design. Through technological integration, it can reduce equipment investment by more than 60%. Due to the reduction in equipment investment, the utilization rate of workshop space can be increased to 40%, significantly reducing equipment production costs and saving workshop space.
