DETAILED DESCRIPTION

[0012] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present application. The terms "mounted," "connected," and "connected" should be interpreted broadly, and may include, for example, fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. The terms "parallel," "perpendicular," and "equal" encompass the described conditions and conditions similar to the described conditions, provided that the range of the similar conditions is within an acceptable range of deviation, as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes both absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism may be, for example, within 5°; "perpendicular" includes both absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity may also be, for example, within 5°.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0014] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0015] The flatness of a circuit board refers to the flatness of its surface, which is a key quality indicator. The flatness of a circuit board is affected by many process steps, such as: Lamination pressure distribution: During the lamination process, if the pressure at the edge is lower than in the center, micro gaps may form between the layers at the edge. These gaps can cause edge warping after the board cools.

[0016] Lamination temperature control: Too high a temperature will cause the substrate material to expand excessively and shrink unevenly after cooling, which will also affect the flatness.

[0017] Surface treatment process (such as chemical plating, electroplating): Uneven plating thickness will cause local stress differences on the surface of the circuit board, which will lead to deformation.

[0018] Influence of deadweight: The weight of the circuit board itself may also cause the board to sag and deform.

[0019] The following combination Figures 1 to 7 , describing embodiments of the present invention.

[0020] According to an embodiment of the present invention, on the one hand, a hot pressing and shaping device is provided, comprising a workbench 1 , a turntable 2 , at least two supporting mechanisms 3 and a first driving mechanism 4 .

[0021] A hot pressing station is provided on a workbench 1. A turntable 2 is rotatably mounted to one side of the hot pressing station. A support mechanism 3 is used to support a hot pressing assembly 301 and a hot pressing mold 302. The support mechanisms 3 have an operating state and a standby state. In the operating state, at least one support mechanism 3 is located at the hot pressing station. In the standby state, the support mechanisms 3 are located on the turntable 2, with the support mechanisms 3 in the standby state spaced apart along the circumference of the turntable 2. A first drive mechanism 4 is capable of driving the support mechanisms 3 to switch between the operating and standby states.

[0022] The hot pressing and shaping device also includes a positioning frame 101. Positioning frame 101 is mounted on the workbench 1 and includes a mounting plate 1011. Mounting plate 1011 is positioned above the hot pressing station. A first power connector 1012 is located on the underside of mounting plate 1011, and a second power connector 303 is located on the upper side of the support mechanism 3. When the support mechanism 3 is in the hot pressing station, the first power connector 1012 can be plugged into the second power connector 303, which then communicates with the hot pressing assembly 301.

[0023] During use of the hot pressing and shaping device of an embodiment of the present invention, at least two supporting mechanisms 3 can be used to carry different types of hot pressing molds 302. When different types of circuit boards need to be hot pressed and shaped, the turntable 2 can be rotated so that the corresponding hot pressing molds 302 are arranged relative to the hot pressing station. The first driving mechanism 4 can switch the corresponding supporting mechanism 3 from a waiting state to a working state, thereby enabling the hot pressing assembly 301 and the hot pressing mold 302 on the supporting mechanism 3 to hot press and shape the circuit board at the hot pressing station.

[0024] When the supporting mechanism 3 is switched to the hot pressing station, the second power supply structure on the supporting mechanism 3 can be automatically connected to the first power supply connector 1012 on the mounting plate 1011, thereby realizing power supply to the hot pressing component 301, which can simplify the steps of installing the hot pressing component 301 to the hot pressing station and prevent wire entanglement.

[0025] Therefore, the hot pressing shaping device of the embodiment of the present invention can quickly switch the hot pressing component 301 and the hot pressing mold 302 on the hot pressing station, and can automatically power the hot pressing component 301 after switching the supporting mechanism 3 to the hot pressing station. The operation is simple and quick, which helps to improve production efficiency and save production capacity and investment costs.

[0026] It should be noted that, in the embodiment of the present application, the number of the supporting mechanisms 3 is not limited, and is based on the ability to meet the hot pressing requirements of the circuit board.

[0027] The function of the hot-pressing assembly 301 is to apply precise, uniform, and stable temperature and pressure to specific bonding areas of the circuit board within a precisely controlled time period, causing the adhesive to melt, flow, infiltrate, eliminate bubbles, form close contact, and ultimately fully solidify. This achieves a strong, reliable, flat, and permanent bond with good electrical performance between the various layers or components of the circuit board, and corrects their shape. The hot-pressing mold 302, used to support the circuit board and located below the hot-pressing assembly 301, can match the shape of the circuit board, ensuring that pressure is applied evenly and without blind spots to the critical areas requiring bonding.

[0028] For example, in an optional embodiment, there are four supporting mechanisms 3 , which are arranged on the turntable 2 at intervals along the circumference of the turntable 2 .

[0029] In one embodiment, the supporting mechanism 3 includes a first connecting portion 310 , and the first driving mechanism 4 includes a first linear driving mechanism 401 and a first lifting mechanism 402 .

[0030] Among them, the first lifting mechanism 402 is connected to the power output end of the first linear drive mechanism 401, the first linear drive mechanism 401 can drive the first lifting mechanism 402 to move along the distance direction between the hot pressing station and the turntable 2, and the first connecting part 310 can be connected to the power output end of the first lifting mechanism 402.

[0031] Through such an arrangement, when any supporting mechanism 3 needs to be switched to the working state, the turntable 2 can be rotated so that the corresponding supporting mechanism 3 is aligned with the hot pressing station, and the first driving mechanism 4 can drive the first lifting mechanism 402 to move to the corresponding position of the supporting mechanism 3, and then the power output end of the first lifting mechanism 402 descends and is connected to the first connecting part 310, and the first driving mechanism 4 drives the first lifting mechanism 402 to move toward the hot pressing station, thereby moving the supporting mechanism 3 to the hot pressing station.

[0032] When the carrying mechanism 3 in the working state needs to be switched to the waiting state, the first driving mechanism 4 can drive the first lifting mechanism 402 to move toward the turntable 2 , thereby carrying the carrying mechanism 3 to move onto the turntable 2 .

[0033] In one embodiment, the first linear drive device may be a device capable of outputting linear motion, such as a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, or a combination of a motor and a rack and pinion.

[0034] In one embodiment, the first lifting mechanism 402 may be a cylinder.

[0035] As a convertible implementation, in an embodiment not shown in the drawings, the first lifting mechanism 402 can also be selected as, for example, a hydraulic cylinder, an electric cylinder, or a combination of a motor and a gear rack.

[0036] In one embodiment, the first connection portion 310 is a docking slot, and a plug plate 4021 is provided on the power output end of the lifting mechanism. The plug plate 4021 can be movably engaged with the docking slot, thereby being able to carry the carrying mechanism 3 to move synchronously.

[0037] It should be noted that in the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" refers to two or more, unless otherwise clearly and specifically defined.

[0038] As a convertible implementation, in an embodiment not shown in the drawings, the connection between the first connecting portion 310 and the power output end of the lifting mechanism can also be selected as a magnetic connection, etc.

[0039] In one embodiment, the first driving mechanism 4 further includes a first fixing frame 4011 and a mounting frame 4014 .

[0040] The first fixed frame 4011 is mounted on the workbench 1 and is located on one side of the hot pressing station. The first linear drive mechanism 401 includes a first rotation source 4012 and a first screw 4013. The first rotation source 4012 is mounted on the first fixed frame 4011, and the first screw 4013 is connected to the power output end of the first rotation source 4012. The mounting frame 4014 is in driving connection with the first screw 4013 and extends to a side of the hot pressing station facing the turntable 2. The first lifting mechanism 402 is mounted on the mounting frame 4014.

[0041] By such arrangement, the cooperation between the first rotation source 4012 and the first screw rod 4013 can drive the mounting bracket 4014 to move along the distance direction between the hot pressing station and the turntable 2 , and the adjustment accuracy is relatively high.

[0042] In one embodiment, the first rotation source 4012 may be a device capable of outputting rotation, such as a motor, an engine, a hydraulic motor, or a combination of one of them and a reducer.

[0043] In one embodiment, a plurality of slide rails 201 are provided on the turntable 2 . The slide rails 201 extend radially of the turntable 2 , and each supporting mechanism 3 is slidably connected to one of the slide rails 201 .

[0044] By such arrangement, the slide rail 201 can be slidably connected to the supporting mechanism 3, thereby limiting the supporting mechanism 3, preventing the supporting mechanism 3 from tilting or deflecting during movement, and reducing the damping of the supporting mechanism 3 during movement.

[0045] In one embodiment, the hot pressing shaping device further includes a connecting member 202. The connecting member 202 includes a first extension section 2021 and a second extension section 2022. The first extension section 2021 is connected to the supporting mechanism 3 and extends in the radial direction of the turntable 2. The second extension section 2022 connects the first extension section 2021 and the slide rail 201.

[0046] Through such an arrangement, the first extension section 2021 of the connecting member 202 extends along the radial direction of the turntable 2, which can expand the range of movement of the supporting mechanism 3 when it moves toward the hot pressing station, and ensure that when the supporting mechanism 3 detaches from the turntable 2 and moves to the hot pressing station, the second extension section 2022 can still be connected to the slide rail 201 and will not interfere with the slide rail 201.

[0047] In one embodiment, the connecting member 202 is an L-shaped plate.

[0048] As an alternative implementation, in an embodiment not shown in the drawings, the connecting member 202 may also be an arc-shaped rod.

[0049] In one embodiment, by such an arrangement, when the supporting mechanism 3 is switched to the hot pressing station, the second power supply structure on the supporting mechanism 3 can be automatically plugged into the first power supply connector 1012 on the mounting plate 1011, thereby realizing power supply to the hot pressing assembly 301, which can simplify the steps of installing the hot pressing assembly 301 to the hot pressing station and prevent wire entanglement.

[0050] In one embodiment, the first power connector 1012 is a power socket, and the second power connector 303 is a power plug.

[0051] In a preferred embodiment, the first power supply connector 1012 and the second power supply connector 303 are blind-plug connectors. When the supporting mechanism 3 enters the hot pressing station, even if there is a certain deviation in the position of the supporting mechanism 3, the blind-plug connector can float and absorb the deviation in the docking process, thereby ensuring that the first power supply connector 1012 and the second power supply connector 303 can be accurately docked.

[0052] In one embodiment, the hot pressing shaping device also includes a second lifting mechanism 5, which is arranged on the mounting plate 1011. The supporting mechanism 3 includes a base frame 304, a slide 305 and a second connecting part 306. The slide 305 is slidably connected to the base frame 304 and can slide in the vertical direction. The hot pressing component 301 is connected to the slide 305. The bottom of the slide 305 is used to set the hot pressing component 301. The second connecting part 306 is arranged on the slide 305. The power output end of the second lifting mechanism 5 can pass through the mounting plate 1011 to connect to the second connecting part 306.

[0053] With this arrangement, when the supporting mechanism 3 is switched to the hot pressing station, the power output end of the second lifting assembly can descend and pass through the mounting plate 1011 to connect with the second connecting portion 306, so that the power output end of the second lifting assembly can drive the slide 305 to carry the hot pressing assembly 301 up and down, thereby cooperating with the hot pressing mold 302 to perform hot pressing and shaping on the circuit board.

[0054] In one embodiment, a guide rail 311 extending in a vertical direction is provided on the base frame 304 , and the slide plate 305 is slidably connected to the guide rail 311 .

[0055] In one embodiment, the hot pressing shaping device further comprises an electromagnetic assembly 501. The electromagnetic assembly 501 is provided at the power output end of the second lifting mechanism 5. The second connecting portion 306 is an electromagnetic matching component, and the electromagnetic assembly 501 can attract the electromagnetic matching component when powered on.

[0056] As a convertible embodiment, the connection between the power output end of the second lifting mechanism 5 and the second connecting structure can also be a snap-on connection.

[0057] In one embodiment, the supporting mechanism 3 further includes a limit frame 307. The limit frame 307 is disposed below the slide 305, the hot pressing mold 302 is disposed on the limit frame 307, and the positioning frame 101 is provided with a spring pin 1013, which passes through the limit frame 307 and abuts against the hot pressing mold 302.

[0058] The limiting frame 307 can limit the hot pressing mold 302, and the spring pin 1013 can pass through the limiting frame 307 and engage with the hot pressing mold 302, thereby completing the limiting of the circuit board to facilitate subsequent hot pressing shaping.

[0059] In one embodiment, the limiting frame 307 is a protruding frame.

[0060] As a convertible implementation, the limiting frame 307 may also be a frame of other shapes.

[0061] In one embodiment, the hot pressing mold 302 is a lower mold.

[0062] During the hot pressing process, the hot pressing assembly 301 can serve as an active heat source and pressure source, and the lower mold can be used to support the circuit board and serve as a precise support, positioning and cooling platform, ultimately achieving reliable hot pressing of the circuit board.

[0063] In one embodiment, the positioning frame 101 includes a support wall 1014 . The support wall 1014 connects the workbench 1 and the mounting plate 1011 . The supporting mechanism 3 also includes a support frame 308 and an elastic member 309 .

[0064] The support frame 308 includes a main section 3081 and a support section 3082 that are interconnected. When the support mechanism 3 is in the hot-pressing state, the main section 3081 is located on the side of the support mechanism 3 away from the operating side. The support section 3082 is movably mounted on the base frame 304. The support section 3082 has a locked state, located below the slide 305, and an unlocked state, avoiding the movement trajectory of the slide 305. An elastic member 309 is supported between the support section 3082 and the main section 3081. The support section 3082 can be switched to the locked state under the support of the elastic member 309. A push block 1015 is provided on the support wall 1014. When the support mechanism 3 is in the hot-pressing state, the push block 1015 can abut against the main section 3081 and switch the support section 3082 to the unlocked state.

[0065] Through such an arrangement, when the supporting mechanism 3 is switched from the waiting state to the working state, the support section 3082 can be in a locked state under the support of the elastic member 309, and then supported under the slide 305, so that the power output end of the second lifting mechanism 5 is connected to the second connecting part 306 on the slide 305.

[0066] When the supporting mechanism 3 is completely switched to the working state, the main section 3081 of the support frame 308 can be abutted against the push block 1015 on the support wall 1014, so that the support frame 308 is switched to the unlocked state. At this time, the power output end of the second lifting mechanism 5 can drive the slide 305 to carry the hot pressing assembly 301 to move in the vertical direction, thereby hot pressing the circuit board on the hot pressing mold 302.

[0067] As a convertible embodiment, in an embodiment not shown in the accompanying drawings, the push block 1015 is arranged on the main section 3081, and the push block 1015 can be abutted against the support wall 1014 when the supporting mechanism 3 is switched to the working state, so that the support frame 308 is switched to the unlocked state.

[0068] As an alternative embodiment, in an embodiment not shown in the drawings, the support frame 308 includes a main section 3081 and a support section 3082 connected to each other. An elastic member 309 is supported between the support section 3082 and the main section 3081. The support section 3082 can be switched to a locked state under the support of the elastic member 309. A guide slope is provided on one end of the support section 3082 facing the operating side of the support mechanism 3. From bottom to top, the guide slope is inclined away from the operating side of the support mechanism 3.

[0069] After the power output end of the second lifting mechanism 5 is connected to the second connecting wall, the power output end of the second lifting mechanism 5 can drive the sliding plate to slide downward when extended, and the support section 3082 can move in the direction away from the operating side of the supporting mechanism 3 under the guidance of the guide slope and be switched to the unlocked state.

[0070] In one embodiment, the supporting mechanism 3 also includes a limiting rod 3083, which passes through the base frame 304 and the main section 3081. The main section 3081 is slidingly connected to the limiting rod 3083. The elastic member 309 is sleeved on the limiting rod 3083. The limiting rod 3083 can limit the elastic member 309 and guide the main section 3081 and the support section 3082 at the same time.

[0071] It should be noted that in the description of the embodiments of the present application, there is no restriction on the number of limiting rods 3083. For example, in an optional embodiment, two limiting rods 3083 are provided on each supporting mechanism 3, and an elastic member 309 is sleeved on each limiting rod 3083.

[0072] The elastic member 309 is preferably, but not limited to, a spring.

[0073] In one embodiment, the support walls 1014 are arranged in pairs and are respectively arranged on both sides of the hot pressing station. Push blocks 1015 are respectively provided on the two support walls 1014. When the supporting mechanism 3 is in the hot pressing state, the two push blocks 1015 can simultaneously resist the main section 3081, thereby ensuring that the two ends of the main section 3081 move synchronously, ensuring that the support frame 308 can reliably support the slide 305 when it is in the locked state, and can completely break away from the movement trajectory of the slide 305 when it is in the unlocked state.

[0074] In one embodiment, the hot pressing shaping device includes a preheating assembly 6. The preheating assembly 6 is provided on at least one side of the hot pressing station and is used to preheat the circuit board to be shaped.

[0075] Through such an arrangement, the preheating component 6 can preheat the circuit board before the formal hot pressing shaping, so that its temperature gradually rises to a temperature range close to that required for hot pressing, thereby reducing the thermal stress of the circuit board caused by excessive temperature difference during the hot pressing process, and improving the shaping quality and product yield.

[0076] In one embodiment, the preheating assembly 6 includes a baffle, a heating wire 602 and a second driving mechanism 607 .

[0077] The baffle is slidably connected to the workbench 1. It has a preheating state, shielding the operating side of the hot pressing station, and a retracted state, exposing the hot pressing station. A heating wire 602 is located on the side of the baffle closest to the hot pressing station. A second drive mechanism 607 is connected to the workbench 1 and can switch the baffle between the preheating state and the retracted state.

[0078] By such a setting, the baffle can block the operating side of the hot pressing station when in the preheating state, thereby preventing the operator from accidentally touching the equipment during operation and causing burns or mechanical injuries while preheating the circuit board, thereby improving the safety of the equipment.

[0079] In one embodiment, the baffle includes a first baffle 603 and a second baffle 604 , and the second driving mechanism 607 includes a second rotation source 6071 , a second screw rod 6072 and a third screw rod.

[0080] The second rotation source 6071 is connected to the workbench 1 and is located below the hot pressing station. A first power output terminal and a second power output terminal are provided on either side of the second rotation source 6071. A second screw 6072 is connected to the first power output terminal, and a first baffle 603 extends through the surface of the workbench 1 and is in transmission connection with the second screw 6072. A third screw is connected to the second power output terminal, and a second baffle 604 extends through the surface of the workbench 1 and is in transmission connection with the third screw. A second drive mechanism 607 is capable of driving the first baffle 603 and the second baffle 604 in opposite directions.

[0081] Through such an arrangement, the second rotation source 6071 can drive the second screw rod 6072 and the third screw rod to rotate simultaneously, thereby driving the first baffle 603 and the second baffle 604 towards each other until the first baffle 603 and the second baffle 604 contact each other, thereby protecting the front side of the hot pressing station and preventing the operator from accidentally touching the equipment during operation and causing burns or mechanical injuries.

[0082] When the second rotation source 6071 is reversed, the second screw 6072 and the third screw can rotate synchronously in opposite directions, thereby driving the first baffle 603 and the second baffle 604 to move synchronously away from each other, thereby exposing the operating side of the hot pressing station.

[0083] In one embodiment, the baffle is a transparent plate, such as an acrylic plate, which can facilitate the operator to observe the hot pressing station.

[0084] In one embodiment, the first baffle 603 and the second baffle 604 each include a first wall capable of shielding the operating side of the hot pressing station, and a second wall connected to the first wall and extending in the distance direction between the hot pressing station and the turntable 2. With this arrangement, when the first baffle 603 and the second baffle 604 abut against each other, they can form an enclosure structure that protects the operating side of the hot pressing station and the two adjacent sides thereof, thereby preventing operators from accidentally touching the equipment during operation and causing burns or mechanical injuries. Furthermore, the circuit board can be preheated from three directions, making the temperature of the circuit board more uniform and helping to improve the preheating effect.

[0085] As a convertible implementation, in an embodiment not shown in the drawings, the first baffle 603 and the second baffle 604 may also be selected to be a flat plate structure or an arc-shaped plate structure.

[0086] In one embodiment, the second rotation source 6071 , the second screw rod 6072 and the third screw rod are arranged under the table surface of the workbench 1 . The workbench 1 also includes a first guide groove 103 , a second guide groove, a first slide rod 605 and a second slide rod 606 .

[0087] The first guide groove 103 and the second guide groove are provided under the table surface of the workbench 1. The first guide groove 103 and the second guide groove are respectively provided on either side of the hot pressing station. The second screw rod 6072 is provided in the first guide groove 103, and the third screw rod is provided in the second guide groove. The table surface of the workbench 1 is provided with a first strip groove 105 and a second strip groove 106. The first end of the first slide rod 605 is slidably provided in the first guide groove 103 and is threadedly connected to the second screw rod 6072. The second end of the first slide rod 605 passes through the first strip groove 105 and is connected to the first baffle 603. The second end of the second slide rod 606 is slidably provided in the second guide groove and is threadedly connected to the third screw rod. The second end of the second slide rod 606 passes through the second strip groove 106 and is connected to the second baffle 604.

[0088] In one embodiment, the hot pressing shaping device further comprises a third rotation source 7 and a shaft 8. The shaft 8 is hinged to the workbench 1, the power output end of the third rotation source 7 is connected to the shaft 8, and the shaft 8 is connected to the turntable 2.

[0089] By such arrangement, the shaft 8 can not only drive the turntable 2 to rotate under the action of the third rotation source 7 , but also limit the rotation of the turntable 2 when the third rotation source 7 stops.

[0090] In one embodiment, the third rotation source 7 is a servo motor.

[0091] As a convertible embodiment, the third rotation source 7 can also be selected as an engine, a hydraulic motor, or a combination of one of them and a speed reducer.

[0092] As a convertible implementation mode, in an embodiment not shown in the drawings, a rotating shaft is provided on the turntable 2, a bearing is provided on the workbench 1, the inner ring of the rotating shaft is connected to the bearing of the turntable 2, and the turntable 2 is rotated by manual turning.

[0093] In one embodiment, the workbench 1 is provided with a support surface 1021 , and a rolling structure 203 is provided at the bottom of the turntable 2 , and the turntable 2 is slidably engaged with the support surface 1021 via the rolling structure 203 .

[0094] The support surface 1021 forms a comprehensive and stable contact with the bottom of the turntable 2, effectively dispersing various stresses generated by the turntable 2 during rotation, including the radial force formed by centrifugal force and the vertical pressure generated by its own weight, thereby significantly reducing the possibility of the turntable 2 shaking, deflecting or tilting, and ensuring the stability and reliability of the turntable 2 during operation. A rolling cooperation relationship is formed between the rolling structure 203 and the supporting surface 1021. When the turntable 2 starts to rotate, the rolling structure 203 can convert the sliding friction that may originally exist between the bottom of the turntable 2 and the supporting surface 1021 into rolling friction. This change in friction form can greatly reduce the frictional resistance between the two, which not only reduces the driving force required during the rotation of the turntable 2 and reduces energy loss, but also effectively avoids abnormal noise, wear and other problems caused by excessive friction, making the rotation of the turntable 2 lighter and smoother, further improving the user experience and service life of the entire equipment.

[0095] In one embodiment, the rolling structure 203 is a ball bearing rotatably connected to the bottom of the turntable 2 at equal intervals.

[0096] As a convertible implementation, in an embodiment not shown in the drawings, the rolling structure 203 can also be a roller rotatably connected to the bottom of the turntable 2 at equal intervals.

[0097] In one embodiment, a clamping groove 102 is provided on the side of the workbench 1 , a supporting surface 1021 is provided on a side wall of the clamping groove 102 , and an edge of the turntable 2 is movably clamped in the clamping groove 102 .

[0098] By setting a snap-fit ​​groove 102 structure on the side of the workbench 1, it can be movably snap-fitted with the edge of the turntable 2. This design can effectively limit the unexpected radial and axial displacement of the turntable 2, thereby significantly improving the dynamic stability and operating accuracy of the turntable 2 during rotation.

[0099] Next, the working process of the hot pressing shaping device according to the embodiment of the present invention is described: First, according to the hot pressing assembly 301 and the hot pressing mold 302 used as needed, the third rotation source 7 drives the turntable 2 to rotate so that the corresponding supporting mechanism 3 is aligned with the hot pressing station on the workbench 1, and then the first rotation source 4012 drives the first screw rod 4013 to rotate, so that the first lifting mechanism 402 comes to the corresponding position of the supporting mechanism 3, and the power output end of the first lifting mechanism 402 extends so that the plug plate 4021 is engaged with the first connecting part 310 on the supporting mechanism 3, and then the first rotation source 4012 drives the first screw rod 4013 to rotate in the opposite direction, and transfers the supporting mechanism 3 from the turntable 2 to the hot pressing station. During the transfer process, the connecting member 202 can slide with the slide rail 201, thereby slidingly limiting the supporting mechanism 3.

[0100] When the carrier mechanism 3 enters the hot pressing station, the second power supply connector 303 on the carrier mechanism 3 can be plugged into the first power supply connector 1012 on the positioning frame 101, thereby providing power to the hot pressing assembly 301. Before the carrier mechanism 3 enters the hot pressing station, the support section 3082 of the support frame 308 can be partially exposed from the operating side of the base frame 304 and supported below the slide 305, thereby facilitating the connection between the electromagnetic assembly 501 of the second lifting mechanism 5 and the second connecting portion 306 on the slide 305. When the carrier mechanism 3 is in place, the support frame 308 can be moved toward the turntable 2 under the action of the push block 1015, and the support for the slide 305 can be released. The spring pin 1013 can be replaced by passing through the limit frame 307 and engaging with the hot pressing mold 302, thereby completing the limit of the circuit board and facilitating subsequent hot pressing shaping.

[0101] The second rotation source 6071 can rotate and drive the second screw 6072 and the third screw to rotate synchronously, thereby driving the first baffle 603 and the second baffle 604 to move toward each other until the first baffle 603 and the second baffle 604 contact each other. The first baffle 603 and the second baffle 604 can protect the operating side of the hot pressing station to prevent the operator from accidentally touching the equipment during operation and causing burns or mechanical injuries, and allow the operator to observe the hot pressing station normally. Before the formal hot pressing shaping operation, the heating wire 602 can be energized and preheat the circuit board to be shaped, so that its temperature gradually rises to a temperature range close to that required for hot pressing. This can reduce the thermal stress of the circuit board caused by excessive temperature difference during the hot pressing process, improve the shaping quality and product yield, and start the second lifting mechanism 5 to drive the hot pressing assembly 301 downward to perform hot pressing shaping on the circuit board.
