[0061] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. In addition, unless explicitly defined herein, terms such as those defined in common dictionaries should be interpreted as having a meaning consistent with their meaning in the relevant art and the content of this application, and will not be interpreted as idealized or overly formal meanings.

[0062] The specific implementation methods of the present application will be described in further detail below with reference to the accompanying drawings.

[0063] like Figures 1 to 2 As shown, and see Figure 5 and Figure 6 This embodiment further provides a correction device 100 , comprising a hot pressing device 10 and a cold pressing device 20 . The correction device 100 is used to correct a bent structure of a workpiece 30 .

[0064] The hot pressing apparatus 10 is used to hot press a workpiece 30 and includes a hot pressing base 13 and a hot pressing module 14. The hot pressing base 13 is used to support the workpiece 30 after placement, with the front surface P1 of the workpiece 30 to be straightened attached to the upper surface of the hot pressing base 13. It is understood that the front surface P1 to be straightened can be a surface on the side of the workpiece 30 that has a curved structure that is excessively curved and requires correction. The front surface P1 to be straightened can also be the outermost surface of the entire curved workpiece 30 along the curvature of the workpiece 30.

[0065] Furthermore, the hot press base 13 heats the workpiece 30 to cause thermal deformation, which in turn imparts a certain degree of fluidity to the workpiece 30, facilitating subsequent deformation and correction of the workpiece 30 by applying pressure. The hot press module 14 is disposed outside the hot press base 13 and is configured to flexibly support the side of the workpiece 30 away from the hot press base 13, thereby applying pressure to the back surface P2 of the workpiece 30, away from the front surface P1 to be corrected.

[0066] The cold press equipment 20 includes a cold press base 24 , a cold press module 25 , and a cold air delivery assembly 26 . The cold press base 24 is used to place and support the workpiece 30 after hot pressing. The back surface P2 of the workpiece 30 is attached to the upper surface of the cold press base 24 .

[0067] The cold press module 25 is disposed outside the cold press base 24 and is used to flexibly support the side of the workpiece 30 away from the cold press base 24 to apply pressure to the front face P1 of the workpiece 30 to be straightened. A first air hole 2410 is defined on the side of the cold press base 24 where the workpiece 30 rests, and a second air hole 2530 is defined on the side of the cold press module 25 that supports the workpiece 30. A cold air delivery assembly 26 connects the first and second air holes 2410, 2530, and is used to deliver cold air to these two holes to cool the workpiece 30.

[0068] Thus, in the correction device 100 of the present application, the hot press 10 first heats the workpiece 30 until it undergoes a certain degree of thermal deformation, and then applies a first press correction to the workpiece 30. After the workpiece 30 completes the first press correction, the cold press 20 applies a second press correction to the workpiece 30. During the second press correction, the cold press 20 simultaneously blows cold air onto the upper and lower sides of the workpiece 30 to rapidly cool and shape the workpiece 30, thereby improving the correction efficiency of the workpiece 30. Furthermore, by applying two press corrections to the workpiece 30, the correction device 100 can improve the correction effect of the workpiece 30.

[0069] For ease of subsequent reading, this application introduces a first direction X, a second direction Y, and a third direction Z to describe the embodiments of the present application. The first direction X, the second direction Y, and the third direction Z can be three non-parallel linear directions in space; further, the first direction X, the second direction Y, and the third direction Z can be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction X is the X-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction Y is the Y-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction Z is the Z-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0070] Please combine again Figures 2 to 4 In one embodiment, the hot pressing device 10 further includes a hot pressing body 11 and a hot pressing mounting plate 12. The hot pressing body 11 is used to mount a control device, a power supply device, and a display device. The hot pressing mounting plate 12 is fixed to the top of the hot pressing body 11 and is placed horizontally.

[0071] The hot pressing base 13 is arranged on the side of the hot pressing mounting plate 12 away from the hot pressing body 11, and the hot pressing base 13 is a roughly rectangular structure. There are multiple hot pressing modules 14, which are arranged on the side of the hot pressing mounting plate 12 away from the hot pressing body 11. Multiple hot pressing modules 14 are arranged around the hot pressing base 13, and can apply pressure to each side of the workpiece 30 placed on the hot pressing base 13, so as to select a similar hot pressing module 14 according to the position of the area to be corrected of the workpiece 30. In addition, each hot pressing module 14 can be detachably connected to the hot pressing mounting plate 12, which is convenient for disassembly and installation of the hot pressing module 14 for maintenance or replacement, or adjustment of the position of the hot pressing module 14 on the hot pressing mounting plate 12.

[0072] Furthermore, the hot press base 13 includes two heating elements 132 and a hot press support 131. The two heating elements 132 are spaced apart on the top end surface of the hot press mounting plate 12 along the first direction X. The heating elements 132 are made of a heat-conducting metal such as brass. They are equipped with a heating tube 16 and a thermocouple 17. When the heating tube 16 is energized, it generates heat that raises the temperature of the heating element 132, and the thermocouple 17 monitors the temperature of the heating element 132.

[0073] The hot press support member 131 is located at the top end of the hot press mounting plate 12 and is clamped between the two heating elements 132. The top ends of the two heating elements 132 and the top ends of the hot press support member 131 are coplanar, so that the two heating elements 132 and the hot press support member 131 jointly support the workpiece 30. The hot press support member 131 is made of Bakelite, which has good insulation and heat resistance.

[0074] Along the second direction Y, first stops 1311 are provided on opposite sides of the end surface of the top end of the hot pressing support member 131. When the workpiece 30 is placed on the hot pressing base 13, the workpiece 30 is pressed against the first stops 1311 on opposite sides along the second direction Y, thereby limiting the position of the workpiece 30 in the second direction Y.

[0075] It is understandable that the position of the first stopper 1311 on the hot pressing support member 131 can be adjusted to accommodate workpieces 30 of different widths.

[0076] The hot pressing base 13 further includes two hot pressing stoppers 133 , which are disposed along the first direction X on one side of the two heating elements 132 away from the hot pressing support element 131 . The hot pressing stoppers 133 are made of a heat-resistant material such as bakelite and are fixed to the top surface of the hot pressing mounting plate 12 .

[0077] The top surfaces of the two hot pressing limiters 133 are both provided with a second stopper 1331. When the workpiece 30 is placed on the hot pressing base 13, the opposite sides of the workpiece 30 along the first direction X abut against the second stopper 1331, thereby limiting the position of the workpiece 30 in the first direction X.

[0078] It is understandable that the position of the second stopper 1331 on the hot pressing limiter 133 can be adjusted to accommodate workpieces 30 of different lengths.

[0079] Please combine again Figures 2 to 4 In one embodiment, the hot pressing module 14 includes a hot pressing connecting member 141 , a hot pressing lifting driving member 142 and a hot pressing plate 143 .

[0080] The heat press connector 141 is located outside the heat press base 13 and is detachably connected to the top surface of the heat press mounting plate 12 to facilitate assembly and disassembly of the heat press connector 141. For example, the heat press connector 141 can be connected to the heat press mounting plate 12 by fasteners such as bolts.

[0081] The hot press lifting and lowering drive 142 is a lifting cylinder connected to the hot press connecting member 141. The hot press lifting and lowering drive 142 is positioned along the third direction Z. The hot press plate 143 is located on the side of the hot press base 13 away from the hot press mounting plate 12. The hot press plate 143 is a flat plate structure with one end extending above the hot press base 13 and the other end connected to the hot press lifting and lowering drive 142. The hot press lifting and lowering drive 142 drives the hot press plate 143 to rise and fall along the third direction Z, thereby causing the hot press plate 143 to move against the workpiece 30. The hot press plate 143 presses the workpiece 30 against the hot press base 13, ensuring full contact between the workpiece 30 and the heating element 132. The hot press plate 143 also provides corrective pressure to the workpiece 30, causing it to deform.

[0082] In particular, the hot pressing lifting drive member 142 can be replaced with a corresponding model of the hot pressing lifting drive member 142 according to the different pressures required during hot pressing, so that the hot pressing equipment 10 has different correction capabilities.

[0083] Furthermore, the hot pressing module 14 further includes a hot pressing proximity switch 15 . The hot pressing proximity switch 15 is disposed on the hot pressing support 131 and is used to detect whether the workpiece 30 is close to the hot pressing support 131 .

[0084] A hot pressing mounting groove 1310 is provided on the top surface of the hot pressing support member 131. The hot pressing proximity switch 15 is accommodated in the hot pressing mounting groove 1310, and its detection end is set upward to detect whether there is a workpiece 30 on the hot pressing base 13 to avoid hot pressing without material.

[0085] Please combine again Figures 5 to 7 , and see Figure 1 In one embodiment, the cold press apparatus 20 is located to one side of the hot press apparatus 10, allowing the workpiece 30, after hot pressing, to be quickly placed on the cold press apparatus 20 for cold pressing. During press correction of the workpiece 30, the cold press apparatus 20 simultaneously blows cold air onto the workpiece 30 from both the top and bottom sides, rapidly shaping the workpiece 30. The cold press apparatus 20 also includes a cold press body 21, connecting columns 22, and a cold press mounting plate 23. The cold press body 21 is used to mount a control device, power supply, and display device.

[0086] The cold press mounting plate 23 is spaced apart and positioned horizontally above the cold press body 21. Four connecting posts 22 are arranged in a rectangular pattern. These connecting posts 22 are located between the cold press mounting plate 23 and the cold press body 21. Their top ends are connected to the cold press mounting plate 23, and their bottom ends are connected to the top surface of the cold press body 21.

[0087] The cold press base 24 is arranged on the side of the cold press mounting plate 23 away from the cold press body 21, and the cold press base 24 is roughly a rectangular structure. There are multiple cold press modules 25, and they are arranged on the side of the cold press mounting plate 23 away from the cold press body 21. Multiple cold press modules 25 are arranged around the cold press base 24, and can apply pressure to each side of the workpiece 30 placed on the cold press base 24, so as to select a similar cold press module 25 according to the position of the area to be corrected of the workpiece 30. In addition, each cold press module 25 can be detachably connected to the cold press mounting plate 23, which is convenient for disassembly and assembly of the cold press module 25 for maintenance or replacement, or adjustment of the position of the cold press module 25 on the cold press mounting plate 23.

[0088] Furthermore, the cold press base 24 includes two cold press support seats 241 and a cold press support member 242. The two cold press support seats 241 are spaced apart on the top surface of the cold press mounting plate 23 along the first direction X. The cold press support seats 241 are made of Bakelite. The cold press support member 242 is disposed on the top surface of the cold press mounting plate 23 and is located between the two cold press support seats 241.

[0089] There are two cold press support members 242 . Along the second direction Y, the two cold press support members 242 are spaced apart from each other, so that the workpiece 30 is supported by the two cold press support members 242 and the two cold press support seats 241 .

[0090] It is understandable that the number of the cold press support member 242 may also be set to one, and the width thereof is the same as the width of the cold press support seat 241 .

[0091] A first air hole 2410 is defined on a side of the cold press support base 241 away from the cold press mounting plate 23 . There are a plurality of first air holes 2410 , which are distributed in an array on the cold press support base 241 .

[0092] The cold press equipment 20 also includes a cold press proximity switch 27. A cold press mounting groove 2420 is defined on the side of the cold press support 242 facing away from the cold press mounting plate 23. The cold press proximity switch 27 is received in the cold press mounting groove 2420 with its detection end facing upward to detect whether a workpiece 30 is on the cold press support 242, thus preventing cold pressing without material.

[0093] Furthermore, a third stopper 232 and a fourth stopper 233 are provided on the top surface of the cold press mounting plate 23 .

[0094] Along the first direction X, third stops 232 are provided on opposite sides of the cold press base 24. When the workpiece 30 is placed on the cold press base 24, the workpiece 30 is pressed against the third stops 232 on opposite sides along the first direction X, thereby limiting the position of the workpiece 30 in the first direction X.

[0095] It is understandable that the position of the third stopper 232 on the cold press mounting plate 23 can be adjusted to accommodate workpieces 30 of different lengths.

[0096] Along the second direction Y, fourth stops 233 are provided on opposite sides of the cold pressing base 24. When the workpiece 30 is placed on the cold pressing base 24, the opposite sides of the workpiece 30 along the second direction Y abut against the fourth stops 233, thereby limiting the position of the workpiece 30 in the second direction Y.

[0097] It is understandable that the position of the fourth stopper 233 on the cold press mounting plate 23 can be adjusted to accommodate workpieces 30 of different widths.

[0098] Please combine again Figures 7 to 9 In one embodiment, a first boss 2411 is provided on a side of the cold press support base 241 away from the cold press mounting plate 23. Two first bosses 2411 are provided to support the side of the workpiece 30. The two first bosses 2411 are spaced apart along the second direction Y, creating a gap between the area between the two first bosses 2411 and the workpiece 30. The first air hole 2410 is located between the two first bosses 2411, allowing the cold air blown from the first air hole 2410 to be more evenly dispersed along the back surface P2 of the workpiece 30, thereby affecting a wider area of ​​the workpiece 30. The cold press module 25 supports the area of ​​the workpiece 30 located between the two first bosses 2411.

[0099] In particular, the protruding length of the first boss 2411 is 0.05 mm. It is understandable that the protruding length of the first boss 2411 may also be 0.06 mm, 0.07 mm, 0.08 mm, or other values, and the specific value may be adaptively adjusted according to actual design requirements.

[0100] A second boss 2421 is formed on the side of the cold press support 242 away from the cold press mounting plate 23. The second boss 2421 and the cold press support 242 are integrally formed and both are made of materials such as PU to prevent damage to the workpiece 30. The second protrusion 2532 is used to support the center of the workpiece 30.

[0101] Specifically, a recess 31 is defined on the back surface P2 of the workpiece 30. The second boss 2421 extends farther than the first boss 2411. The second boss 2421 abuts against the bottom wall of the recess 31, while the first boss 2411 abuts against the back surface P2 of the workpiece 30, ensuring that the workpiece 30 is placed horizontally on the cold press base 24.

[0102] It is understandable that when the back surface P2 of the workpiece 30 is flat and no slot 31 is provided, in order to place the workpiece 30 horizontally on the cold pressing base 24 , the second boss 2421 and the first boss 2411 have the same protruding distance.

[0103] Please combine again Figures 5 to 7 In one embodiment, the cold press module 25 includes a cold press lifting drive member 251, a cold press connecting member 252, and a cold press plate 253. The cold press lifting drive member 251 is detachably connected to the cold press mounting plate 23 and is located outside the cold press base 24.

[0104] The top surface of the cold press mounting plate 23 defines a mounting hole 231 extending through the cold press mounting plate 23 along the third direction Z. The cold press lift actuator 251, a lifting cylinder, is positioned along the third direction Z. The cold press lift actuator 251 is partially installed within the mounting hole 231, thereby securing the cold press lift actuator 251 relative to the cold press mounting plate 23. The bottom end of the cold press lift actuator 251 extends into the space between the cold press body 21 and the cold press mounting plate 23, while the top end of the cold press lift actuator 251 extends above the cold press mounting plate 23.

[0105] In particular, the number of mounting holes 231 can be multiple, and the multiple mounting holes 231 are spaced apart and located on different sides of the cold press base 24, so that the cold press lifting driver 251 can be installed in the mounting holes 231 at different positions, thereby adjusting the position of the cold press lifting driver 251 on the cold press mounting plate 23 to apply pressure to different positions of the workpiece 30. When adjusting the position of the cold press lifting driver 251, it is necessary to ensure that the cold press plate 253 is located above the cold press support seat 241, so that the cold press plate 253 and the cold press support seat 241 cooperate to act on the upper and lower sides of the workpiece 30.

[0106] The cold press connector 252 is a flat plate-shaped structure, one end of which is driven and connected to the cold press lifting drive 251. The cold press lifting drive 251 drives the cold press connector 252 to rise and fall along the third direction Z. The cold press plate 253 is fixed to the bottom end surface of the cold press connector 252 away from the cold press lifting drive 251, and the cold press plate 253 is always located on the side of the cold press base 24 away from the cold press mounting plate 23.

[0107] The cold press plate 253 rises and falls along the third direction Z with the cold press connector 252 so that the cold press plate 253 can move against the workpiece 30, thereby pressing the workpiece 30 onto the cold press base 24 through the cold press plate 253, and the cold press plate 253 provides a corrective pressure on the workpiece 30 to deform the workpiece 30.

[0108] In particular, the cold pressing lifting driving member 251 can be replaced with a corresponding model of the cold pressing lifting driving member 251 according to the different pressures required during cold pressing, so that the cold pressing equipment 20 has different correction capabilities.

[0109] A second air hole 2530 is defined on a side of the cold pressing plate 253 close to the cold pressing base 24 .

[0110] The cold air delivery assembly 26 includes a first delivery valve 261, a second delivery valve 262, and a cold air generating element (not shown). The first delivery valve 261 is fixed to the cold press mounting plate 23. The top end of the first delivery valve 261 passes through the cold press mounting plate 23 and connects to the first air hole 2410. The bottom end of the first delivery valve 261 is located in the space between the cold press mounting plate 23 and the cold press body 21 and connects to the cold air generating element.

[0111] The second delivery valve 262 is fixed to the top of the cold pressure connector 252 . The bottom of the second delivery valve 262 passes through the cold pressure connector 252 and is connected to the second air hole 2530 . The top of the second delivery valve 262 is connected to the cold air generating element.

[0112] The cold air generating element is a condensation valve or other element, which is used to cool the gas flowing through the condensation valve. It is understood that the cold air delivery assembly 26 also includes an air pump or other device for delivering gas to the condensation valve, and the gas passing through the condensation valve is delivered to the first air hole 2410 and the second air hole 2530.

[0113] Please combine again Figures 5 to 8 , and see Figure 2 In one embodiment, a first protrusion 2531 and a second protrusion 2532 are provided on one side of the cold press plate 253 near the cold press base 24. The first protrusion 2531 and the second protrusion 2532 are used to support the workpiece 30. The first protrusion 2531 and the second protrusion 2532 are integrally formed with the cold press plate 253, and the first protrusion 2531, the second protrusion 2532, and the cold press plate 253 are all made of materials such as PU.

[0114] Along the first direction X, the first protrusion 2531 is spaced apart from the second protrusion 2532 on a side away from the cold press lifting and lowering drive member 251. An air groove 2533 is formed between the first and second protrusions 2531, 2532. The second air hole 2530 is provided in the bottom wall of the air groove 2533 and communicates with the air groove 2533. Cool air can be concentrated through the air groove 2533 to the area to be straightened on the workpiece 30, thereby improving the straightening effect.

[0115] The protruding length of the first protrusion 2531 is smaller than the protruding length of the second protrusion 2532 to adapt to the curved state of the surface P1 to be corrected along the first direction X. This allows the cold press plate 253 to better fit the surface P1 to be corrected via the first and second protrusions 2531, 2532. For example, the difference between the protruding lengths of the first and second protrusions 2531, 2532 is 1 mm. It is understood that the difference between the protruding lengths of the first and second protrusions 2531, 2532 can also be other values, such as 1.5 mm or 2 mm. The specific value can be adaptively selected based on the curvature of the curved structure to be corrected.

[0116] The specific embodiments of the present application have been described above with reference to the accompanying drawings. However, those skilled in the art will appreciate that various modifications and substitutions may be made to the specific embodiments of the present application without departing from the scope of the present application. Such modifications and substitutions are within the scope of the present application.
