Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing technology, and specifically to a hot pressing shaping device. Background Technology

[0002] The flatness of a circuit board is an important quality indicator. Many factors during the circuit board manufacturing process can cause unevenness on the surface of the circuit board, which can affect the soldering of components and the assembly of the whole machine. Therefore, hot pressing shaping equipment is needed to heat press the circuit board to shape it.

[0003] However, different hot-pressing shaping devices are required for different types of circuit boards, which means that the hot-pressing shaping devices need to be replaced frequently. This makes the operation cumbersome, reduces production efficiency, and wastes production capacity and investment costs. Summary of the Invention

[0004] In view of this, the present invention provides a hot pressing shaping device to solve the problem in the related technology that the hot pressing shaping device needs to be replaced frequently, which is cumbersome to operate, reduces production efficiency, and wastes production capacity and input costs.

[0005] This application provides a hot pressing shaping apparatus, comprising:

[0006] The workbench is equipped with a hot pressing station;

[0007] A turntable is rotatably mounted on one side of the hot pressing station;

[0008] At least two support mechanisms are provided, which are used to support the hot pressing assembly and the hot pressing mold. The support mechanisms have a working state and a waiting state. In the working state, at least one support mechanism is located at the hot pressing station. In the waiting state, it is located on the turntable. The support mechanisms in the waiting state are arranged at intervals along the circumference of the turntable.

[0009] The first drive mechanism is capable of driving the carrier mechanism to switch between working state and waiting state;

[0010] The positioning frame, located on the workbench, includes a mounting plate. The mounting plate is positioned above the hot pressing station. A first power supply connector is located on the lower side of the mounting plate, and a second power supply connector is located on the upper side of the supporting mechanism. When the supporting mechanism is located at the hot pressing station, the first power supply connector can be plugged into the second power supply connector, and the second power supply connector is communicatively connected to the hot pressing assembly.

[0011] According to this application, during the use of the hot pressing shaping device of the present invention, at least two supporting mechanisms can be used to support different types of hot pressing molds. When different types of circuit boards need to be hot pressed and shaped, the turntable can be rotated so that the corresponding hot pressing mold is set opposite to the hot pressing station. The first driving mechanism can switch the corresponding supporting mechanism from the waiting state to the working state, so that the hot pressing components and hot pressing molds on the supporting mechanism can perform hot pressing and shaping on the circuit board at the hot pressing station.

[0012] Based on this, when the carrier mechanism is switched to the hot pressing station, the second power supply structure on the carrier mechanism can automatically connect to the first power supply connector on the mounting plate, thereby realizing the power supply to the hot pressing component. This simplifies the steps of installing the hot pressing component to the hot pressing station and prevents wire twisting.

[0013] Therefore, the hot pressing shaping device of this invention can quickly switch between the hot pressing components and the hot pressing mold at the hot pressing station, and can automatically supply power to the hot pressing components after switching the bearing mechanism to the hot pressing station. The operation is simple and quick, which helps to improve production efficiency and save production capacity and input costs. Attached Figure Description

[0041] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Circuit board flatness refers to the flatness of its surface, a key quality indicator. Circuit board flatness is affected by various manufacturing processes, such as:

[0043] Lamination pressure distribution: During the lamination process, if the pressure in the edge areas is lower than that in the center areas, micro-gaps may form between the edge layers. After the circuit board cools, these gaps can cause edge warping.

[0044] Lamination temperature control: Excessive temperature will cause the substrate material to expand excessively and shrink unevenly after cooling, which will also affect the flatness.

[0045] Surface treatment processes (such as chemical plating and electroplating): Uneven plating thickness can cause local stress differences on the circuit board surface, which can lead to deformation.

[0046] Self-weight effect: The weight of the circuit board itself may also cause the board to dent and deform.

[0047] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0048] According to an embodiment of the present invention, a hot pressing shaping device is provided, including a worktable 1, a turntable 2, at least two supporting mechanisms 3 and a first driving mechanism 4.

[0049] The workbench 1 is equipped with a hot pressing station. A turntable 2 is rotatably mounted on one side of the hot pressing station. A support mechanism 3 supports the hot pressing assembly 301 and the hot pressing mold 302. The support mechanism 3 has a working state and a waiting state. In the working state, at least one support mechanism 3 is located at the hot pressing station; in the waiting state, the support mechanism 3 is located on the turntable 2. The support mechanisms 3 in the waiting state are spaced apart circumferentially along the turntable 2. A first drive mechanism 4 can drive the support mechanism 3 to switch between the working state and the waiting state.

[0050] The hot pressing shaping device also includes a positioning frame 101. The positioning frame 101 is mounted on the workbench 1 and includes a mounting plate 1011. The mounting plate 1011 is located above the hot pressing station. A first power supply connector 1012 is provided on the lower side of the mounting plate 1011, and a second power supply connector 303 is provided on the upper side of the supporting mechanism 3. When the supporting mechanism 3 is located at the hot pressing station, the first power supply connector 1012 can be plugged into the second power supply connector 303, and the second power supply connector 303 is communicatively connected to the hot pressing assembly 301.

[0051] In the hot pressing shaping device of this embodiment of the invention, at least two supporting mechanisms 3 can be used to support different types of hot pressing molds 302. When different types of circuit boards need to be hot pressed, the turntable 2 can be rotated so that the corresponding hot pressing mold 302 is set opposite to the hot pressing station. The first driving mechanism 4 can switch the corresponding supporting mechanism 3 from the waiting state to the working state, so that the hot pressing component 301 and the hot pressing mold 302 on the supporting mechanism 3 can perform hot pressing shaping on the circuit board at the hot pressing station.

[0052] When the bearing mechanism 3 is switched to the hot pressing station, the second power supply structure on the bearing mechanism 3 can automatically connect to the first power supply connector 1012 on the mounting plate 1011, thereby realizing the power supply to the hot pressing assembly 301. This simplifies the steps of installing the hot pressing assembly 301 to the hot pressing station and prevents wire twisting.

[0053] Therefore, the hot pressing shaping device of this embodiment can quickly switch between 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 the carrying mechanism 3 is switched to the hot pressing station. The operation is simple and quick, which helps to improve production efficiency and save production capacity and input costs.

[0054] It should be noted that in this embodiment, the number of bearing mechanisms 3 is not limited, but is determined by the ability to meet the hot pressing requirements of the circuit board.

[0055] 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. This allows the adhesive to melt, flow, wet, remove air bubbles, achieve tight contact, and ultimately cure completely. This results in a strong, reliable, flat, and electrically sound permanent bond between the layers of the circuit board or between different components, and also corrects its shape. The hot-pressing mold 302 carries the circuit board and is located below the hot-pressing assembly 301. It matches the shape of the circuit board, ensuring that pressure is applied evenly and without dead angles to the critical bonding areas.

[0056] For example, in an optional embodiment, there are four support mechanisms 3, which are arranged at circumferential intervals on the turntable 2.

[0057] In one embodiment, the supporting mechanism 3 includes a first connecting part 310, and the first driving mechanism 4 includes a first linear driving mechanism 401 and a first lifting mechanism 402.

[0058] 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 between the hot pressing station and the turntable 2. The first connecting part 310 can be connected to the power output end of the first lifting mechanism 402.

[0059] With this configuration, when any of the supporting mechanisms 3 needs to be switched to the working state, the turntable 2 can rotate so that the corresponding supporting mechanism 3 is aligned with the hot pressing station. The first drive mechanism 4 can drive the first lifting mechanism 402 to move to the corresponding position of the supporting mechanism 3. Then, the power output end of the first lifting mechanism 402 descends and connects to the first connecting part 310. The first drive 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.

[0060] When it is necessary to switch the working support mechanism 3 to the waiting state, the first drive mechanism 4 can drive the first lifting mechanism 402 to move toward the turntable 2, thereby carrying the support mechanism 3 onto the turntable 2.

[0061] 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.

[0062] In one embodiment, the first lifting mechanism 402 may be a cylinder.

[0063] As an alternative implementation, in an embodiment not shown in the accompanying drawings, the first lifting mechanism 402 may also be selected as, for example, a hydraulic cylinder, an electric cylinder, or a combination of a motor and a rack and pinion.

[0064] In one embodiment, the first connecting part 310 is a docking groove, and the power output end of the lifting mechanism is provided with a plug plate 4021. The plug plate 4021 can be movably engaged with the docking groove, thereby enabling the carrying mechanism 3 to move synchronously.

[0065] 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 construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0066] As an alternative implementation, in an embodiment not shown in the accompanying drawings, the connection between the first connecting part 310 and the power output end of the lifting mechanism may also be a magnetic connection or the like.

[0067] In one embodiment, the first drive mechanism 4 further includes a first fixing frame 4011 and a mounting frame 4014.

[0068] The first fixed frame 4011 is mounted on the workbench 1 and located on one side of the hot pressing station. The first linear drive mechanism 401 includes a first rotation source 4012 and a first lead screw 4013. The first rotation source 4012 is mounted on the first fixed frame 4011, and the first lead screw 4013 is connected to the power output end of the first rotation source 4012. The mounting frame 4014 is connected to the first lead screw 4013 and extends to the side of the hot pressing station facing the turntable 2. The first lifting mechanism 402 is mounted on the mounting frame 4014.

[0069] With this configuration, the first rotation source 4012 and the first lead screw 4013 can work together to drive the mounting bracket 4014 to move along the distance between the hot pressing station and the turntable 2, and the adjustment accuracy is high.

[0070] In one embodiment, the first rotation source 4012 may be a device capable of outputting rotation, such as an electric motor, an engine, a hydraulic motor, or a combination of one of these with a speed reducer.

[0071] In one embodiment, the turntable 2 is provided with a plurality of slide rails 201. The slide rails 201 extend radially along the turntable 2, and each support mechanism 3 is slidably connected to one slide rail 201.

[0072] With this configuration, the slide rail 201 can be slidably connected to the bearing mechanism 3, thereby limiting the bearing mechanism 3, preventing it from tilting or shifting during movement, and reducing the damping of the bearing mechanism 3 during movement.

[0073] In one embodiment, the hot pressing shaping device further includes a connector 202. The connector 202 includes a first extension 2021 and a second extension 2022. The first extension 2021 is connected to the support mechanism 3 and extends in the radial direction of the turntable 2. The second extension 2022 connects the first extension 2021 and the slide rail 201.

[0074] With this configuration, the first extension 2021 of the connector 202 extends in the radial direction of the turntable 2, which can expand the range of motion of the bearing mechanism 3 when it moves toward the hot pressing station. This ensures that when the bearing mechanism 3 leaves the turntable 2 and moves to the hot pressing station, the second extension 2022 can still be connected to the slide rail 201 and will not interfere with the slide rail 201.

[0075] In one embodiment, the connector 202 is an L-shaped plate.

[0076] As an alternative implementation, in an embodiment not shown in the accompanying drawings, the connector 202 may also be an arc-shaped rod.

[0077] In one embodiment, by such a configuration, when the support mechanism 3 is switched to the hot pressing station, the second power supply structure on the support mechanism 3 can automatically connect to the first power supply connector 1012 on the mounting plate 1011, thereby providing power to the hot pressing assembly 301. This simplifies the steps of installing the hot pressing assembly 301 to the hot pressing station and prevents wire twisting.

[0078] In one embodiment, the first power connector 1012 is a power socket, and the second power connector 303 is a power plug.

[0079] In a preferred embodiment, the first power supply connector 1012 and the second power supply connector 303 are blind-fit connectors. When the bearing mechanism 3 enters the hot pressing station, even if there is a certain deviation in the position of the bearing mechanism 3, the blind-fit connector can float and absorb the deviation in the docking process, ensuring that the first power supply connector 1012 and the second power supply connector 303 can be accurately docked.

[0080] In one embodiment, the hot pressing shaping device further includes a second lifting mechanism 5, which is mounted on the mounting plate 1011. The supporting mechanism 3 includes a base frame 304, a sliding plate 305, and a second connecting part 306. The sliding plate 305 is slidably connected to the base frame 304 and can slide in the vertical direction. The hot pressing assembly 301 is connected to the sliding plate 305. The bottom of the sliding plate 305 is used to set the hot pressing assembly 301. The second connecting part 306 is mounted on the sliding plate 305. The power output end of the second lifting mechanism 5 can pass through the mounting plate 1011 and connect to the second connecting part 306.

[0081] With this configuration, when the supporting mechanism 3 is switched to the hot pressing station, the power output end of the second lifting component can descend and pass through the mounting plate 1011 to connect to the second connecting part 306, so that the power output end of the second lifting component can drive the slide plate 305 to lift and lower the hot pressing component 301. Then, in conjunction with the hot pressing mold 302, the circuit board is hot-pressed and shaped.

[0082] In one embodiment, the base frame 304 is provided with a guide rail 311 extending in a vertical direction, and the slide plate 305 is slidably connected to the guide rail 311.

[0083] In one embodiment, the hot pressing shaping device further includes an electromagnetic component 501. The electromagnetic component 501 is located at the power output end of the second lifting mechanism 5. The second connecting part 306 is an electromagnetic coupling component, and the electromagnetic component 501 can attract the electromagnetic coupling component when energized.

[0084] As an alternative implementation, the connection between the power output end of the second lifting mechanism 5 and the second connecting structure can also be a snap-fit ​​connection.

[0085] In one embodiment, the supporting mechanism 3 further includes a limiting frame 307. The limiting frame 307 is located below the sliding plate 305, the hot pressing mold 302 is located on the limiting frame 307, and the positioning frame 101 is provided with a spring pin 1013, which passes through the limiting frame 307 and abuts against the hot pressing mold 302.

[0086] 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 and shaping.

[0087] In one embodiment, the limiting frame 307 is a C-shaped frame.

[0088] As an alternative implementation, the limiting frame 307 can also be selected as a frame of other shapes.

[0089] In one embodiment, the hot pressing mold 302 is a lower mold.

[0090] During the hot pressing process, the hot pressing component 301 can serve as an active heat and pressure source, and the lower mold can be used to support the circuit board and serve as a precision support, positioning and cooling platform, ultimately achieving reliable hot pressing of the circuit board.

[0091] In one embodiment, the positioning frame 101 includes a support wall 1014. The support wall 1014 connects the worktable 1 and the mounting plate 1011, and the bearing mechanism 3 also includes a support frame 308 and an elastic element 309.

[0092] The support frame 308 includes a main body section 3081 and a support section 3082 connected to each other. When the bearing mechanism 3 is in a hot-pressed state, the main body section 3081 is located on the side of the bearing 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 under the slide plate 305 and an unlocked state that avoids the movement trajectory of the slide plate 305. An elastic member 309 is supported between the support section 3082 and the main body section 3081. The support section 3082 can be switched to the locked state with the support of the elastic member 309. A push block 1015 is provided on the support wall 1014. When the bearing mechanism 3 is in a hot-pressed state, the push block 1015 can abut against the main body section 3081 and switch the support section 3082 to the unlocked state.

[0093] With this configuration, during the process of the load-bearing mechanism 3 being switched from the waiting state to the working state, the support section 3082 can be locked under the support of the elastic member 309, and thus supported under the slide plate 305, so that the power output end of the second lifting mechanism 5 can be connected to the second connecting part 306 on the slide plate 305.

[0094] When the bearing mechanism 3 is fully switched to the working state, the main body section 3081 of the support frame 308 can abut against the push block 1015 on the support wall 1014, thereby switching the support frame 308 to the unlocked state. At this time, the power output end of the second lifting mechanism 5 can drive the slide plate 305 to carry the hot pressing component 301 to move in the vertical direction, thereby hot pressing the circuit board on the hot pressing mold 302.

[0095] As an alternative implementation, in an embodiment not shown in the accompanying drawings, a pusher 1015 is disposed on the main body section 3081. The pusher 1015 is able to abut against the support wall 1014 when the support mechanism 3 is switched to the working state, thereby causing the support frame 308 to be switched to the unlocked state.

[0096] As a possible implementation, in an embodiment not shown in the accompanying drawings, the support frame 308 includes a main body segment 3081 and a support segment 3082 connected to each other. An elastic member 309 is supported between the support segment 3082 and the main body segment 3081, and the support segment 3082 can be switched to a locked state with the support of the elastic member 309. A guide slope is provided at one end of the support segment 3082 facing the operating side of the bearing mechanism 3, and the guide slope is inclined from bottom to top in a direction away from the operating side of the bearing mechanism 3.

[0097] When 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 it extends, and the support section 3082 can move away from the operating side of the bearing mechanism 3 under the guidance of the guide slope and be switched to the unlocked state.

[0098] In one embodiment, the supporting mechanism 3 further includes a limiting rod 3083, which passes through the base frame 304 and the main body section 3081. The main body section 3081 is slidably connected to the limiting rod 3083. An elastic element 309 is sleeved on the limiting rod 3083. The limiting rod 3083 can limit the elastic element 309 and guide the main body section 3081 and the support section 3082.

[0099] It should be noted that the number of limiting rods 3083 is not limited in the description of the embodiments of this application. For example, in an optional embodiment, each bearing mechanism 3 is provided with two limiting rods 3083, and each limiting rod 3083 is fitted with an elastic member 309.

[0100] Among them, the elastic element 309 is preferably, but not limited to, a spring.

[0101] In one embodiment, the support walls 1014 are arranged in pairs and respectively located on both sides of the hot pressing station. Each of the two support walls 1014 is provided with a push block 1015. When the bearing mechanism 3 is in the hot pressing state, the two push blocks 1015 can simultaneously abut against the main body section 3081, thereby ensuring that the two ends of the main body section 3081 move synchronously. This ensures that the support frame 308 can reliably support the slide plate 305 when it is in the locked state, and can completely disengage from the movement trajectory of the slide plate 305 when it is in the unlocked state.

[0102] In one embodiment, the hot pressing shaping apparatus includes a preheating component 6. The preheating component 6 is disposed on at least one side of the hot pressing station and is used to preheat the circuit board to be shaped.

[0103] With this configuration, the preheating component 6 can preheat the circuit board before the formal hot pressing and shaping, gradually raising its temperature to close to the temperature range required for hot pressing. This reduces the thermal stress on the circuit board caused by excessive temperature difference during hot pressing, thereby improving the shaping quality and product yield.

[0104] In one embodiment, the preheating component 6 includes a baffle, a heating wire 602, and a second drive mechanism 607.

[0105] The baffle is slidably connected to the worktable 1. The baffle has a preheating state that shields the operating side of the hot pressing station, and a clearance state that exposes 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 worktable 1 and can drive the baffle to switch between the preheating state and the clearance state.

[0106] With this configuration, the baffle can shield the operating side of the hot pressing station when it is in the preheating state, thereby preventing operators from accidentally touching the circuit board during equipment operation and causing burns or mechanical injuries, thus improving equipment safety.

[0107] In one embodiment, the baffle includes a first baffle 603 and a second baffle 604, and the second drive mechanism 607 includes a second rotation source 6071, a second lead screw 6072 and a third lead screw.

[0108] The second rotation source 6071 is connected to the worktable 1 and located below the hot pressing station. A first power output end and a second power output end are respectively located on both sides of the second rotation source 6071. A second lead screw 6072 is connected to the first power output end, and a first baffle 603 passes through the surface of the worktable 1 and is connected to the second lead screw 6072. A third lead screw is connected to the second power output end, and a second baffle 604 passes through the surface of the worktable 1 and is connected to the third lead screw. The second drive mechanism 607 can drive the first baffle 603 and the second baffle 604 to move in opposite directions.

[0109] With this configuration, the second rotation source 6071 can drive the second lead screw 6072 and the third lead screw to rotate simultaneously, thereby driving the first baffle 603 and the second baffle 604 to face each other until the first baffle 603 and the second baffle 604 come into contact with each other, thus protecting the front side of the hot pressing station and preventing operators from accidentally contacting the equipment during operation and causing burns or mechanical injuries.

[0110] When the second rotation source 6071 reverses, the second lead screw 6072 and the third lead screw can rotate synchronously in opposite directions, thereby driving the first baffle 603 and the second baffle 604 to move synchronously in opposite directions, thus exposing the operating side of the hot pressing station.

[0111] In one embodiment, the baffle is a transparent plate, such as an acrylic plate, which allows the operator to easily observe the hot pressing station.

[0112] 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 along the distance 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 form a protective enclosure structure that shields the operating side of the hot pressing station and the two sides adjacent to it. This prevents operators from accidentally contacting the equipment during operation and causing burns or mechanical injuries. Furthermore, it allows for preheating of the circuit board from three directions, resulting in a more uniform temperature distribution and improved preheating effect.

[0113] As a possible implementation, in an embodiment not shown in the accompanying drawings, the first baffle 603 and the second baffle 604 may also be selected as a flat plate structure or an arc-shaped plate structure.

[0114] In one embodiment, the second rotation source 6071, the second lead screw 6072, and the third lead screw are disposed under the table surface of the worktable 1. The worktable 1 also includes a first guide groove 103, a second guide groove, a first slide rod 605, and a second slide rod 606.

[0115] The first guide groove 103 and the second guide groove are located under the table surface of the workbench 1. The first guide groove 103 and the second guide groove are respectively located on both sides of the hot pressing station. The second lead screw 6072 is located in the first guide groove 103, and the third lead screw is located 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 located in the first guide groove 103 and is threadedly connected to the second lead screw 6072. The second end of the first slide rod 605 passes through the first strip groove 105 and connects to the first baffle 603. The second end of the second slide rod 606 is slidably located in the second guide groove and is threadedly connected to the third lead screw. The second end of the second slide rod 606 passes through the second strip groove 106 and connects to the second baffle 604.

[0116] In one embodiment, the hot pressing shaping device further includes a third rotation source 7 and a shaft 8. The shaft 8 is hinged to the worktable 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.

[0117] With this configuration, the shaft 8 can both drive the turntable 2 to rotate under the action of the third rotation source 7 and limit the rotation of the turntable 2 when the third rotation source 7 stops.

[0118] In one embodiment, the third rotation source 7 is a servo motor.

[0119] As an alternative implementation, the third rotation source 7 may also be an engine, a hydraulic motor, or a combination of one of them and a speed reducer.

[0120] As an alternative implementation, in one embodiment not shown in the accompanying drawings, the turntable 2 is provided with a rotating shaft, the worktable 1 is provided with a bearing, the inner ring of the rotating shaft is connected to the bearing of the turntable 2, and the turntable 2 is rotated manually.

[0121] In one embodiment, the workbench 1 is provided with a support surface 1021, and the bottom of the turntable 2 is provided with a rolling structure 203. The turntable 2 slides in cooperation with the support surface 1021 through the rolling structure 203.

[0122] By forming a comprehensive and stable contact with the bottom of the turntable 2, the support surface 1021 effectively disperses various stresses generated by the turntable 2 during rotation, including radial forces caused by centrifugal force and vertical pressure caused by its own weight. This significantly reduces the possibility of the turntable 2 shaking, shifting or tilting, ensuring the stability and reliability of the turntable 2 during operation.

[0123] A rolling fit relationship is formed between the rolling structure 203 and the support 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 support surface 1021 into rolling friction. This change in the form of friction can greatly reduce the frictional resistance between the two, which not only reduces the driving force required for the turntable 2 to rotate and reduces energy loss, but also effectively avoids problems such as abnormal noise and wear caused by excessive friction, making the rotation of the turntable 2 lighter and smoother, and further improving the user experience and service life of the entire device.

[0124] In one embodiment, the rolling structure 203 is a ball bearing that is equidistantly rotatably connected to the bottom of the turntable 2.

[0125] As an alternative implementation, in an embodiment not shown in the accompanying drawings, the rolling structure 203 may also be a roller rotatably connected to the bottom of the turntable 2 at equal intervals.

[0126] In one embodiment, the side of the workbench 1 is provided with a snap-fit ​​groove 102, the support surface 1021 is provided on one side wall of the snap-fit ​​groove 102, and the edge of the turntable 2 is movably snapped into the snap-fit ​​groove 102.

[0127] By setting a snap-fit ​​groove 102 structure on the side of the worktable 1, it can be movably snapped into the edge of the turntable 2. This design can effectively limit the unexpected displacement of the turntable 2 in the radial and axial directions, thereby significantly improving the dynamic stability and running accuracy of the turntable 2 during rotation.

[0128] The working process of the hot pressing shaping device according to an embodiment of the present invention will be described below:

[0129] First, based on the hot pressing assembly 301 and hot pressing mold 302 required, the third rotation source 7 drives the turntable 2 to rotate so that the corresponding bearing mechanism 3 is aligned with the hot pressing station on the worktable 1. Then, the first rotation source 4012 drives the first lead screw 4013 to rotate so that the first lifting mechanism 402 comes to the corresponding position of the bearing mechanism 3. The power output end of the first lifting mechanism 402 extends so that the insert plate 4021 engages with the first connecting part 310 on the bearing mechanism 3. Then, the first rotation source 4012 drives the first lead screw 4013 to rotate in the opposite direction, transferring the bearing mechanism 3 from the turntable 2 to the hot pressing station. During the transfer, the connecting piece 202 can slide and cooperate with the slide rail 201 to limit the sliding of the bearing mechanism 3.

[0130] 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 partially protrude from the operating side of the base frame 304 and be supported under the slide plate 305, thus facilitating the connection between the electromagnetic assembly 501 of the second lifting mechanism 5 and the second connecting part 306 on the slide plate 305. After the carrier mechanism 3 is in position, the support frame 308 can move towards the turntable 2 under the action of the push block 1015 and release the support on the slide plate 305. 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 and facilitating subsequent hot pressing shaping.

[0131] The second rotation source 6071 can rotate and drive the second lead screw 6072 and the third lead screw to rotate synchronously, thereby driving the first baffle 603 and the second baffle 604 to move towards each other until the first baffle 603 and the second baffle 604 come into contact with each other. The first baffle 603 and the second baffle 604 can protect the operating side of the hot pressing station, preventing operators from accidentally contacting the equipment during operation and causing burns or mechanical injuries, and allowing operators to observe the hot pressing station normally. Before the formal hot pressing and shaping operation, the heating wire 602 can be energized and preheat the circuit board to be shaped, gradually raising its temperature to close to the temperature range required for hot pressing. This can reduce the thermal stress on the circuit board caused by excessive temperature difference during hot pressing, improve the shaping quality and product yield, and activate the second lifting mechanism 5 to drive the hot pressing assembly 301 to move down and perform hot pressing and shaping on the circuit board.

[0132] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope of protection claimed by the present invention.
