Description

Technical Field

[0001] This invention relates to the field of automated processing technology, and in particular to a hot pressing device and a production bus. Background Technology

[0002] With the continuous development of automation technology, hot pressing has become a key process widely used in product assembly, alongside processes such as bonding, dispensing, screwing, and hot melting. In the production processes of various products, these processes collectively play a vital role in improving the stability and functionality of product assembly. Among them, hot pressing, due to its unique ability to ensure connection strength and bonding accuracy, is increasingly expanding its application scenarios to multiple sub-sectors such as electronics, hardware, and plastics, significantly increasing its widespread use.

[0003] In related hot pressing technology, in order to avoid the backing adhesive affecting the hot pressing effect, the backing adhesive cannot be used to pre-fix the hot pressing material in the process. This means that the relative position between the hot pressing material and the product cannot be fixed during the time when they are moved to the hot pressing station after assembly. During this process, factors such as start-stop inertia and the flatness of the moving path will cause relative displacement between the two, resulting in hot pressing deviation.

[0004] Therefore, in order to avoid hot pressing deviations, current hot pressing equipment is semi-automatic. In the hot pressing process, operators need to manually place the hot pressing material precisely onto the product, and then the hot pressing mechanism of the equipment completes the pressing action to finally achieve hot pressing processing. Although this ensures the accuracy of hot pressing, it is not conducive to improving production efficiency. Summary of the Invention

[0005] The main objective of this invention is to provide a hot pressing device that aims to ensure the relative position between the hot pressing material and the workpiece through automation, thereby improving production efficiency while ensuring the accuracy of hot pressing.

[0006] To achieve the above objectives, the hot pressing equipment is used to hot press materials and workpieces, and the hot pressing equipment includes: The base is provided with a transfer tooling, a transfer module, a material feeding assembly, a fixing assembly, and a hot pressing assembly; The transfer fixture is movably disposed on the transfer module, and the transfer fixture is configured to carry the workpiece; The material feeding assembly is configured to place the hot-pressed material onto the workpiece located in the transfer fixture; The fixing component is configured to fix the relative position between the hot-pressed material and the workpiece located on the transfer fixture. The fixing component includes a fixing drive and a fixing action, the fixing action being connected to the fixing drive. The hot-pressing component has a movable adapter, and the end of the fixing action is inserted into the adapter. The hot pressing assembly is configured to hot press the hot pressing material and the workpiece located on the transfer fixture; The hot pressing equipment has a preheating pressing state. In the preheating pressing state, the transfer tool and the transfer tool are in a limiting fit, and the end of the fixing part is inserted into the transfer tool.

[0007] In one embodiment of the present invention, the adapter tool is provided with a first mating hole, the transfer tool is provided with a second mating hole, the fixing part is limited in the first mating hole, and is provided corresponding to the second mating hole.

[0008] In one embodiment of the present invention, the fixing drive is a vacuum adsorption pump, and the end of the fixing part away from the vacuum adsorption pump is provided with an air nozzle, which is inserted into the first mating hole. Under the preheated and pressurized state, the air nozzle extends to the second mating hole.

[0009] In one embodiment of the present invention, the fixing component further includes a support plate, which is disposed on the transfer module; The adapter tooling is matched with the support plate for limiting.

[0010] In one embodiment of the present invention, the transfer module includes a loading and unloading conveying unit, a workpiece handling unit, a material handling unit, and a hot pressing moving unit; The material feeding component is movably mounted on the material handling unit, and the hot pressing component and the transfer tool are mounted on the hot pressing moving unit; The workpiece handling unit is configured to move the transfer tooling between the hot pressing moving unit and the loading and unloading conveying unit.

[0011] In one embodiment of the present invention, the workpiece handling unit is disposed near a first side of the base, the material handling unit is disposed near a second side of the base, and the loading and unloading conveying unit is disposed near a third side of the base. The first side, the second side, and the third side enclose a hot pressing area, and the hot pressing moving unit is located in the hot pressing area. The first side and the second side are aligned on the base along a first direction, and the third side is located on the same side of the first side and the second side along a second direction on the base. The first direction is perpendicular to the second direction.

[0012] In one embodiment of the present invention, the hot pressing equipment further includes a material feeding module, which is movably disposed at one end of the material handling unit away from the loading and unloading conveying unit; The material feeding module is configured to provide hot-pressed material.

[0013] In one embodiment of the present invention, the hot pressing equipment further includes a correction component, the correction component including a first visual inspection element and a second visual inspection element, the first visual inspection element being disposed in the material feeding module, and the second visual inspection element being disposed in the material loading component; The first visual inspection component is configured to acquire relative position information between the material feeding assembly and the hot-pressed material, and the second visual inspection component is configured to acquire relative position information between the hot-pressed material and the workpiece.

[0014] In one embodiment of the present invention, the hot pressing equipment further includes a lifting mechanism, which is located at the end of the loading and unloading conveying unit near the material handling unit; The lifting mechanism is configured to lift the transfer tooling.

[0015] The present invention also proposes a production bus, which includes the hot pressing equipment described in any one of the above-mentioned methods.

The transfer fixture is movably mounted on the transfer module and is used to carry the workpiece. The material feeding component can automatically place the hot pressing material onto the workpiece on the transfer fixture, replacing manual feeding and solving the problem of semi-automatic equipment relying on manual placement. Secondly, the fixing component can fix the relative position of the hot pressing material and the workpiece on the transfer fixture. This design specifically solves the problem of relative displacement during the transfer process caused by the lack of adhesive pre-fixation. After the material feeding component completes the placement of the hot pressing material, the fixing component can lock the position of the two in time, avoiding relative displacement caused by factors such as start-stop inertia and path flatness when the transfer module moves the transfer fixture later, thus ensuring the accurate position of the two before hot pressing. Finally, the hot pressing component can hot press the hot pressing material and workpiece that have been fixed in position on the transfer fixture. The entire process, from workpiece loading, hot pressing material feeding, position fixing to hot pressing, is completed automatically by the equipment without manual intervention. In this way, by effectively fixing the relative position of the hot-pressed material and the workpiece by fixing the components, the problem of relative displacement during the transfer process is completely solved, ensuring the accuracy of hot pressing and avoiding hot pressing deviation. In this process, the fixing components replace manual operation, greatly reducing the manual intervention links, significantly improving production efficiency, and avoiding the errors that may be caused by manual operation, further improving the stability and consistency of hot pressing processing.

[0024] The main objective of this invention is to provide a hot pressing device that aims to ensure the relative position between the hot pressing material and the workpiece through automation, thereby improving production efficiency while ensuring the accuracy of hot pressing.

[0025] To achieve the above objectives, hot pressing equipment is used to hot press materials and workpieces. Please refer to [link / reference]. Figure 1The hot pressing equipment includes a base 10, which is provided with a transfer fixture 20, a transfer module 30, a material feeding component, a fixing component 50, and a hot pressing component 60. The transfer fixture 20 is movably disposed on the transfer module 30 and is configured to carry a workpiece. The material feeding component is configured to place the hot pressing material onto the workpiece located on the transfer fixture 20. The fixing component 50 is configured to fix the relative position between the hot pressing material and the workpiece located on the transfer fixture 20, and the fixing component 50 includes a fixing... The hot pressing assembly 60 has a drive member 51 and a fixing part 52, the fixing part 52 is connected to and fixed the drive member 51, the hot pressing assembly 60 has a movable adapter 61, and the end of the fixing part 52 is inserted into the adapter 61; the hot pressing assembly 60 is configured to hot press hot pressing materials and workpieces located on the transfer fixture 20; the hot pressing equipment has a preheating pressing state, in the preheating pressing state, the adapter 61 is limited to the transfer fixture 20, and the end of the fixing part 52 away from the adapter 61 is inserted into the transfer fixture 20.

[0026] Specifically, the base 10 is the overall support structure of the hot pressing equipment, typically made of high-strength metal materials such as cast steel or aluminum alloy, and its structural form is "flat plate or frame type". Its top surface is precision milled to ensure flatness, used for the stable installation of the transfer module 30, material feeding assembly, fixing assembly 50, and hot pressing assembly 60. The base 10 also has reserved cable trays and air pipe channels to accommodate the equipment's electrical control lines and pneumatic pipelines, preventing external interference from affecting the stability of the components' operation. The base 10 also has a control system, integrated inside or to the side of the base 10. Its core is a programmable logic controller (PLC) or industrial computer (IPC), equipped with corresponding motion control cards, temperature control modules, and I / O modules. The control system communicates with the various execution components and sensors of the equipment via industrial Ethernet or fieldbus (such as Profinet or EtherCAT), coordinating and sequentially controlling the automated operation of the entire hot pressing process.

[0027] The transfer fixture 20 is used to carry the workpiece as it moves between components. In one embodiment, the workpiece is a flat surface, such as the casing of a mobile phone, a small speaker, or other smart device. The surface of the transfer fixture 20 has shallow grooves that match the size of the workpiece, and the inner wall of the grooves is attached with anti-slip silicone pads. In this way, when the workpiece and the transfer fixture 20 move around on the base 10, the workpiece can be prevented from moving relative to the transfer fixture 20, thus avoiding hot pressing errors caused by the workpiece moving during subsequent hot pressing operations. In another embodiment, each workpiece has a through hole, and the transfer fixture 20 has a mating hole that matches the through hole of the workpiece. When the workpiece is placed on the surface of the transfer fixture 20, the through hole corresponds to the mating hole. In this way, the fixing component 50 can be fixed by vacuum adsorption or magnetic attraction. The negative pressure or magnetic attraction can be applied to the hot pressing material through the mating hole and the through hole in sequence, thereby fixing the position between the workpiece and the hot pressing material.

[0028] The transfer module 30 is used to realize the transfer of the transfer fixture 20 on the base 10. The transfer module 30 includes one or more of the following: a conveyor belt, a linear guide, and a robot. In one embodiment, the transfer module 30 includes a conveyor belt and three linear guides. For ease of explanation, the three linear guides are defined as the first linear guide, the second linear guide, and the third linear guide. The first and second linear guides each have a mover that moves directionally along the guide rail. The mover of the first linear guide is equipped with a gripper device, which includes multiple driving components and multiple openable and closeable grippers. The driving components can be servo motors or servo cylinders. The control system controls the operation of the driving components, thereby driving the grippers to move towards and away from the transfer work and opening and closing the multiple grippers, thereby achieving the clamping and fixing of the transfer fixture 20. The mover of the second linear guide is equipped with a vacuum adsorption device. The nozzle of the vacuum adsorption device is used to adsorb hot-pressed materials. In one embodiment, the transfer fixture 20 carrying the workpiece moves to a position close to the first linear rail via a conveyor belt. Then, the gripper device moves along the mover to above the transfer fixture 20. Driven by multiple driving components, the gripper moves down to grip the transfer motor and then places it on the third linear rail. The transfer motor moves along the third linear rail to a position close to the second linear rail. The vacuum adsorption device of the second linear rail places the hot-pressed material onto the workpiece of the transfer fixture 20, followed by fixation and hot pressing. In another embodiment, the transfer module 30 includes a conveyor belt, a linear rail, and two robotic arms. The conveyor belt is used for the transfer fixture 20 to flow in. Then, one robotic arm places the transfer fixture 20 onto the linear rail. The transfer fixture 20 moves along the linear rail to a position close to the other robotic arm. The other robotic arm, not limited to using gripping, vacuum adsorption, electrostatic adsorption, etc., places the hot-pressed material onto the transfer fixture 20, followed by fixation and hot pressing.

[0029] The material feeding assembly 40 is an automated structure that precisely places hot-pressed materials, such as heat-conducting sheets and metal connecting sheets, onto the workpiece. In one embodiment, the material feeding assembly consists of a material storage unit and a material transfer unit. The material storage unit is a vibratory feeder, and the material transfer unit has a vacuum adsorption device. The vacuum adsorption device consists of a vacuum generator, a vacuum suction cup, and a lifting cylinder. The suction cup adsorbs the hot-pressed material on the vibratory feeder through negative pressure. The adsorption force can be adjusted by a vacuum valve to avoid damaging the hot-pressed material. In another embodiment, the material transfer unit consists of pneumatic fingers, gripper arms, and anti-slip pads. The gripper arms can adjust their opening and closing width according to the material size, making them suitable for gripping hard, non-deformable materials such as metal sheets. The hot-pressed material is placed onto the workpiece located in the transfer fixture 20 by gripping, thus realizing the assembly of the hot-pressed material and the transfer fixture 20.

[0030] The fixing component 50 is the core structure for fixing the relative position of the hot-pressed material and the workpiece. In one embodiment, the fixing component 50 consists of a bracket, a lifting cylinder, and a pressure head. The bracket is fixed above the base 10, and the piston rod of the lifting cylinder is connected to the pressure head. The pressure head can be made of high-temperature resistant resin to avoid scratching the material. When the transfer fixture 20 is in place, the cylinder drives the pressure head to descend, pressing the material onto the surface of the workpiece. The pressing force can be controlled by a pressure regulating valve to ensure a firm fixation without damaging the material / workpiece. In another embodiment, to accommodate workpieces with through holes, the fixing component 50 consists of a vacuum generator, an air pipe, and an air nozzle. The transfer fixture 20 has a mating hole that aligns with the through hole. One end of the air pipe is connected to the vacuum generator, and the other end corresponds to the mating hole of the transfer fixture 20. When the material is placed on the workpiece, the vacuum generator is activated, generating negative pressure through the air pipe to adsorb the material onto the surface of the workpiece, achieving non-contact fixing with the hot-pressed material.

[0031] The hot pressing assembly 60 is the execution structure for hot pressing materials and workpieces. It consists of a heating unit, a pressure unit, and a positioning unit. The heating unit includes a hot pressing head, a temperature sensor, and a temperature control module. The hot pressing head has a built-in heating rod and can be made of a copper alloy with high thermal conductivity and nickel-plated surface for anti-oxidation treatment. The temperature control module can set the temperature according to process requirements and provide real-time feedback through the temperature sensor to achieve closed-loop temperature control. The pressure unit is driven by a servo motor or cylinder, which drives the hot pressing head to descend through a ball screw or piston rod to apply hot pressing pressure. The pressure accuracy can be adjusted through feedback from the pressure sensor. A guide sleeve is provided below the hot pressing head, which cooperates with the positioning pin on the transfer tooling 20 to ensure that the hot pressing head is accurately aligned with the material when descending.

[0032] To facilitate the loading, unloading, and hot pressing of materials, the transfer module 30 has at least a workpiece handling station, a material loading station, and a hot pressing station. At the workpiece handling station, the transfer fixture 20, carrying a workpiece but not the hot pressing material, completes its first transfer. At the material loading station, the hot pressing material is placed onto the workpiece by the material loading component. After the hot pressing material and the workpiece are assembled, the fixing component 50 is activated so that the hot pressing material and the workpiece maintain a fixed relative position during the transfer fixture 20's journey from the material loading station to the hot pressing station, thereby preventing relative displacement between the hot pressing material and the workpiece before hot pressing.

[0033] In this technical solution, a transfer fixture 20, a transfer module 30, a material feeding component, a fixing component 50, and a hot pressing component 60 are provided on the base 10 of the hot pressing equipment. The transfer fixture 20 is movably mounted on the transfer module 30 and is used to carry the workpiece. The material feeding component can automatically place the hot-pressed material onto the workpiece on the transfer fixture 20, replacing manual feeding and solving the problem of semi-automatic equipment relying on manual placement. Secondly, the fixing component 50 can fix the relative position of the hot-pressed material and the workpiece on the transfer fixture 20. This design specifically solves the problem of pre-adhesive backing. The fixing component 50 addresses the relative displacement issue during the transfer process by effectively fixing the material. After the material feeding component places the hot-pressing material, the fixing component 50 promptly locks their positions, preventing relative displacement caused by factors such as start-stop inertia and path flatness when the transfer module 30 moves the transfer fixture 20. This ensures accurate positioning of the two components before hot pressing. Finally, the hot pressing component 60 performs hot pressing on the fixed material and workpiece on the transfer fixture 20. The entire process, from workpiece loading, hot-pressing material feeding, and position fixing to hot pressing, is automated and requires no manual intervention. Thus, by effectively fixing the relative positions of the hot-pressing material and workpiece with the fixing component 50, the relative displacement problem during the transfer process is completely solved, ensuring hot pressing accuracy and avoiding deviations. In this process, the fixing component 50 replaces manual operation, significantly reducing manual intervention and improving production efficiency. It also avoids errors that may be caused by manual operation, further enhancing the stability and consistency of hot pressing processing.

[0034] Further, please refer to Figure 2 and Figure 3 The fixing component 50 includes a fixing drive component 51 and a fixing action part 52. The fixing action part 52 is connected to the fixing drive component 51. The hot pressing component 60 has a movable adapter 61. The adapter 61 is inserted into the end of the fixing action part 52. The hot pressing equipment has a preheating pressing state. In the preheating pressing state, the adapter 61 is limited to the transfer tool 20, and the end of the fixing action part 52 is inserted into the transfer tool 20.

[0035] In this embodiment, the fixing component 50 and the hot pressing component 60 are integrated. Thus, the fixing part 52 can be close to the adapter 61 located in the hot pressing component 60. The adapter 61 is used to cooperate with the output end of the fixing part 52. The output end of the fixing part 52 is limited in the adapter, so that in the preheating and pressing state, the fixing part 52 can directly act on the hot pressing material, so that the hot pressing material and the workpiece can be fixed in relative position. Specifically, the adapter 61 is provided with multiple positioning pins, and the transfer tool 20 is provided with positioning holes adapted to the positioning pins. The transfer module 30 places the transfer tool 20 in the adapter 61, and then the transfer tool 20 moves with the adapter 61 to the material loading station and the hot pressing station. With the help of the adapter 61, the end of the fixing part 52 can be inserted and limited in the adapter 61. In this way, during the operation of the hot pressing equipment, the end of the fixing part 52 and the adapter 61 are always in a fixed state. Thus, after the adapter 61 and the transfer tooling 20 are assembled, the fixing part 52 of the fixing component 50 can directly act on the hot pressing material to fix the relative position between the hot pressing material and the workpiece. This avoids the need to fix the fixing component 50 and the transfer tooling 20 every time the hot pressing material and the workpiece are fixed, thereby improving the working efficiency of the hot pressing equipment.

[0036] In one embodiment of the present invention, please refer to Figure 2 and Figure 3 The adapter 61 is provided with a first mating hole, the transfer tool 20 is provided with a second mating hole, and the fixing part 52 is limited in the first mating hole and is provided corresponding to the second mating hole.

[0037] In this embodiment, the first mating hole is a linear straight hole that runs from the bottom surface of the adapter 61 to the top surface of the adapter 61. The first mating hole is aligned with the second mating hole. The fixing part 52 is limited to the first mating hole. When the hot-pressed material is a magnetic metal part, such as a stainless steel connecting piece or an iron heat-conducting sheet, the fixing component 50 can be magnetically attracted. Specifically, the fixing drive 51 of the fixing component 50 is a servo electric cylinder, and the fixing part 52 is a magnetic head with a built-in electromagnetic coil. The coil uses high-temperature resistant enameled wire to avoid the influence of hot pressing heat. The end of the magnetic head is provided with a circular adsorption surface. During operation, when the material feeding component accurately places the hot-pressed magnetic metal material onto the preset position of the workpiece on the transfer fixture 20 through vacuum adsorption or clamping, the control system receives a "alignment qualified" signal from the alignment detection sensor (such as a fiber optic sensor) on the transfer fixture 61. Then, it drives the fixed drive component 51 to drive the magnetic suction head to insert into the first mating hole from the bottom surface of the transfer fixture. The magnetic suction head rises at a constant speed along the linear straight hole, passing through the first mating hole and the second mating hole in sequence. Its adsorption surface comes into close contact with the surface of the hot-pressed material. The control system immediately energizes the electromagnetic coil of the magnetic suction head and outputs a set current according to the parameters of the hot-pressed material to generate a stable magnetic field that firmly adsorbs the hot-pressed material onto the surface of the workpiece, thus fixing the relative position of the two. During the process of the transfer fixture 20 moving from the material loading station to the hot pressing station along with the transfer fixture 61, the fixed component 50 remains in a magnetic state. The magnetic head is always limited to the surface of the hot pressing material through the first mating hole and the second mating hole, completely avoiding the relative displacement problem caused by start-stop inertia and path flatness in the traditional non-fixed design. After reaching the hot pressing station, the fixed component 50 stops working, and the hot pressing head of the hot pressing component 60 is precisely aligned with the hot pressing material with the cooperation of the guide sleeve and the positioning pin on the transfer fixture 20, so as to perform hot pressing. After the hot pressing is completed, the transfer module 30 then moves the transfer fixture 20 out of the hot pressing station, completing one automated hot pressing cycle.

[0038] By utilizing the first mating hole of the adapter tool 61, for hot pressing materials of magnetic metal parts of different sizes, only the appropriate magnetic suction head and the bushing with the straight hole diameter need to be replaced, without modifying the main structure of the adapter tool 61, thereby improving the versatility of the equipment. This linear straight hole design supports quick changeover - ultimately achieving the core goal of "automated and precise fixing - efficient hot pressing - low maintenance cost", ensuring hot pressing accuracy and significantly improving production efficiency. In one embodiment of the present invention, please refer to Figure 2 and Figure 3 The fixed drive component 51 is a vacuum adsorption pump, and the fixed action part 52 is provided with an air nozzle at the end away from the vacuum adsorption pump. The air nozzle is inserted into the first mating hole. Under preheated and pressurized conditions, the air nozzle extends to the second mating hole.

[0039] In this embodiment, as Figure 2 and Figure 3 As shown, the first mating hole of the adapter 61 is an "L" shaped hole. The first mating hole forms an insertion port on the side of the adapter 61 and an insertion port on the top surface of the adapter 61. The end of the fixing part 52 away from the fixing drive part 51 passes through the insertion port and the insertion port in sequence and can enter the second mating hole so as to fix the relative position of the hot-pressed material and the workpiece. When the hot-pressed material has a through hole, the fixing part 52 is a vacuum adsorption structure, which is a combination of an air pipe and an air nozzle. The air nozzle is located at the output end of the air pipe away from the fixed drive member 51. The air nozzle is limited to the insertion port of the first mating hole, and part of the structure protrudes from the top surface of the adapter 61. After the transfer fixture 20 and the adapter 61 are assembled, part of the air nozzle is embedded in the second mating hole. The vacuum adsorption pump is started, generating negative pressure. This adsorption force is transmitted to the air nozzle through the air pipe and finally acts on the surface of the material through the through hole on the hot-pressed material. Thus, the hot-pressed material is stably adsorbed and fixed on the workpiece without physical contact, ensuring that it does not shift during subsequent transfer and hot pressing.

[0040] In one embodiment of the present invention, please refer to Figure 4 The fixing component 50 also includes a support plate 53, which is disposed on the transfer module 30; the adapter 61 is limited to the support plate 53.

[0041] In this embodiment, the support plate 53 is mounted on the transfer module 30 and moves back and forth between the workpiece handling station, the material loading station, and the hot pressing station as the transfer module 30 operates. Specifically, the surface of the support plate 53 is provided with limiting structures adapted to the adapter 61, such as positioning grooves, raised positioning blocks, or positioning pins. When the adapter 61 is placed on the support plate 53, the two are precisely engaged by the limiting structures, preventing the adapter 61 from vibrating during the movement of the transfer module 30. Inertia may cause deviation or wobbling; this limiting fit design provides a stable bearing base for the adapter tool 61, ensuring that the first mating hole of the adapter tool 61 can always be precisely aligned with the second mating hole of the subsequent assembly transfer tool 20, allowing the fixing part 52 of the fixing component 50 (such as an air nozzle or magnetic suction head) to be smoothly inserted and act on the hot-pressed material without additional adjustment of the hole alignment. On the other hand, the transfer module 30 drives the support plate 53, the adapter tool 61, and the transfer tool 20. When the components are switched to a single workstation, the support plate 53 can buffer the impact generated by the movement of the transfer module 30, reducing the risk of relative displacement between the transfer fixture 61, the transfer fixture 20, and the fixing part 52, and further ensuring the relative positional accuracy of the hot-pressed material and the workpiece. At the same time, the presence of the support plate 53 also indirectly optimizes the ease of installation and maintenance of the transfer fixture 61. When it is necessary to replace the transfer fixture 61 with a different specification, the old fixture can be removed simply by releasing the limiting fit between the support plate 53 and the transfer fixture 61, without disassembling the transfer module 30 or the fixing component 50, making the operation simpler. In addition, the support plate 53 can protect the transfer fixture 61, preventing it from directly contacting the transfer module 30 rigidly and causing wear, thus extending the service life of the transfer fixture 61. Finally, through the limiting coordination of the "support plate 53-transfer fixture 61", a more stable structural support is provided for the full-process automation of the hot-pressing equipment from workpiece handling and material loading to hot pressing, helping the equipment to improve operational reliability while ensuring accuracy. In one embodiment of the present invention, please refer to Figure 4 , Figure 5 as well as Figure 6 The transfer module 30 includes a loading and unloading conveying unit 31, a workpiece handling unit 32, a material handling unit 33, and a hot pressing moving unit 34; the material loading component is movably disposed in the material handling unit 33, and the hot pressing component 60 and the transfer tooling are disposed in the hot pressing moving unit 34; the workpiece handling unit 32 is configured to transfer the transfer tooling 20 between the hot pressing moving unit 34 and the loading and unloading conveying unit 31.

[0042] In this embodiment, the loading and unloading conveying unit 31 consists of two parallel conveyor belts. For ease of explanation, the two conveyor belts are defined as the first conveyor belt and the second conveyor belt. The conveying directions of the first conveyor belt and the second conveyor belt can be the same or opposite. For example, when the conveying directions of the first conveyor belt and the second conveyor belt are the same, the two conveyor belts can alternately convey the transfer tooling 20, thereby reducing the waiting time of the material handling unit 33. When the conveying directions of the first conveyor belt and the second conveyor belt are the same, the first conveyor belt is used to load the transfer tooling 20 that has not been hot-pressed, and the second conveyor belt is used to unload the transfer tooling 20 that has been hot-pressed. Different conveyor belts are used to complete different process actions, thereby improving the loading and unloading efficiency.

[0043] The workpiece handling unit 32 includes a linear guide and a workpiece handling device. The workpiece handling device is mounted on the mover of the linear guide and moves back and forth between the loading / unloading conveying unit 31 and the hot pressing moving unit 34 to accurately transport the transfer fixture 20 carrying the workpiece on the loading / unloading conveying unit 31 to the transfer fixture 61 of the hot pressing moving unit 34. After hot pressing is completed, the transfer fixture 20 carrying the finished product is transported from the transfer fixture 61 back to the unloading end of the loading / unloading conveying unit 31. The workpiece handling device is a gripper-type structure, which includes at least a first drive component that controls the lifting and lowering of the gripper and a second drive component that controls the opening and closing of the gripper. Through the cooperation of the two drive components, the workpiece handling unit 32 can transfer the transfer fixture 20 between different workstations.

[0044] The material handling unit 33 is an XY-axis linear module. The material loading component includes a hopper and a vacuum adsorption transfer device. The vacuum adsorption transfer device is mounted on the mover of the linear module. The mover can move the vacuum adsorption transfer device between the hopper and the transfer fixture 61 of the hot pressing moving unit 34. When the workpiece handling unit 32 completes the pre-assembly of the transfer fixture 20 and the transfer fixture 61, the vacuum adsorption transfer device has already obtained the hot-pressed material from the hopper through vacuum adsorption. When the transfer fixture 20 moves toward the material handling unit 33, the vacuum adsorption transfer device moves toward the transfer fixture 61 and finally moves to the top of the transfer fixture 20. During this process, the vacuum adsorption transfer unit accurately places the hot-pressed material with through holes (such as a flexible thermal pad or a porous metal sheet) into the shallow groove on the top surface of the transfer fixture 20, ensuring that the through holes of the material, the through holes of the workpiece, and the second mating hole of the transfer fixture 20 are aligned.

[0045] The hot pressing moving unit 34 is a high-precision linear guide structure. The transfer tool 61 is set on the guide rail. The transfer tool 61 can move back and forth between the workpiece handling station, the material loading station, and the hot pressing station. After the material loading is completed, the hot pressing moving unit 34 drives the transfer tool 61 to move to the hot pressing station. After the hot pressing is completed, it returns to the workpiece handling station and waits for the next cycle.

[0046] In the specific workflow, firstly, the loading and unloading conveying unit 31 transports the transfer fixture 20, which only carries the workpiece, to the loading end. The grippers of the workpiece handling unit 32 grab the transfer fixture 20 and transport it to the transfer fixture 61 of the hot pressing moving unit 34, completing the pre-assembly of the two fixtures. The control system confirms the assembly is qualified through the alignment sensor. Subsequently, the transfer fixture 20 moves along the hot pressing moving unit 34 toward the material handling unit 33. Then, the material loading component moves above the transfer fixture 61 and places the hot-pressed material onto the workpiece of the transfer fixture 20, ensuring that the hot-pressed material is aligned with the workpiece. Next, the vacuum adsorption pump of the fixing component 50 is turned on. The air nozzle is rotated so that the suction force generated by the air nozzle acts between the hot-pressed material and the workpiece, ensuring that their relative positions are fixed. Then, the hot-pressing moving unit 34 drives the transfer tooling 61 and the transfer tooling 20 to the hot-pressing station. When the hot-pressing head of the hot-pressing assembly 60 is accurately aligned with the material with the assistance of the guide sleeve, the fixing assembly 50 stops working and the control system starts hot pressing. After hot pressing is completed, the hot-pressing moving unit 34 drives the transfer tooling 61 and the transfer tooling 20 to the workpiece handling station. The workpiece handling device of the workpiece handling unit 32 transports the transfer tooling 20 carrying the finished product to the unloading end of the loading and unloading conveying unit 31, and enters the next cycle.

[0047] In one embodiment of the present invention, please refer to Figure 1 The workpiece handling unit 32 is located near the first side of the base 10, the material handling unit 33 is located near the second side of the base 10, and the loading and unloading conveying unit 31 is located near the third side of the base 10. The first side, the second side, and the third side enclose a hot pressing area, and the hot pressing moving unit 34 is located in the hot pressing area. The first side and the second side are aligned on the base 10 along the first direction, and the third side is located on the same side of the first side and the second side along the second direction on the base 10. The first direction is perpendicular to the second direction.

[0048] In this embodiment, the first side and the second side are aligned along one direction of the base 10, and the third side is located on the same side of the two sides in the vertical direction. The central hot-pressing area enclosed by the three sides allows the workpiece handling unit 32 and the material handling unit 33 to operate from both ends of the base 10 toward the central hot-pressing area. The loading and unloading conveying unit 31 realizes the tooling entry and exit from the third side. The operation paths of each unit do not intersect each other. The workpiece handling unit 32 does not need to cross the operation range of the material handling unit 33, and the material loading component does not need to bypass the loading and unloading conveying path. This completely avoids the process blockage caused by the cross interference of each unit in the traditional layout, and allows the tooling handling, material loading, hot-pressing movement and other actions to be connected in an orderly manner. Even some links can be prepared in parallel, which greatly shortens the total time of a single process. Meanwhile, this layout concentrates the core hot-pressing moving unit 34 in the middle of the base 10, with the surrounding units compactly distributed along the sides. This avoids the space waste caused by the scattered placement of sub-units and makes the hot-pressing area the "central hub" for the operation of each unit. All sub-units move around the hot-pressing area, eliminating the need for excessively long movement paths and reducing the ineffective time required for unit movement. At the same time, the operating space reserved outside the side loading and unloading conveying unit 31 facilitates the loading and unloading of tooling by personnel or automated equipment without occupying the core operating area, allowing the entire equipment to maximize its functionality within the limited base 10 area. Based on this layout, the workpiece handling unit 32 moves the tooling to the hot pressing area from one side and assembles it with the transfer tooling 61. The material handling unit 33 directly delivers materials to the assembled tooling from the other side, completing the loading without adjusting the position. The air nozzle of the fixing component 50 can be easily inserted into the L-shaped hole from the matching direction to achieve fixation due to the ample space in the hot pressing area. The hot pressing moving unit 34 can complete the hot pressing alignment by moving within the central area. Each link achieves "seamless connection" due to the layout adaptation, without the need for additional adjustment of unit positions or waiting for other units to avoid it. This ensures that the entire process from tooling loading, material placement, fixing to hot pressing is automated and smooth, effectively guaranteeing the relative positional accuracy of the hot-pressed material and the workpiece, and avoiding positioning deviations caused by chaotic movement.

[0049] In one embodiment of the present invention, please refer to Figure 1 and Figure 5 The hot pressing equipment also includes a material feeding module 70, which is movably located at one end of the material handling unit 33 away from the loading and unloading conveying unit 31. The material feeding module 70 is configured to provide hot-pressed materials.

[0050] In this embodiment, the material feeding module 70 is a material feeder, which works in conjunction with an XY-axis two-dimensional linear guide. The material feeder has a feeding disc, and its position can be changed in real time by moving along the XY-axis two-dimensional linear guide, thereby adjusting the position of the hot-pressed material relative to the material feeding component, thus improving the alignment accuracy between the material feeding component and the hot-pressed material. The material feeding module 70 is movably located at the end of the material handling unit 33 away from the loading / unloading conveying unit 31, and its height is adapted to the layout of the hot-pressing area enclosed by three sides of the base, further improving the automated supply chain of the hot-pressed material. Based on the unit layout of the previous embodiment, the material feeding module 70 is placed in the material handling unit 33 away from the loading / unloading conveying unit 31. One end of the material supply module 70 will not occupy the operating space of the loading and unloading conveying unit 31, nor will it interfere with the working path of the workpiece handling unit 32. This will create a clear division between the material supply area and the core hot pressing area and tooling loading and unloading area, avoiding spatial conflicts between material supply and tooling flow and hot pressing operations. At the same time, the material supply module 70 can directly provide hot-pressed materials to the material loading component on the material handling unit 33 without the need for additional conveying structures. The material loading component (such as the vacuum adsorption transfer unit) can quickly pick up materials from the supply module through the movement of the material handling unit 33 and then directly transfer them to the transfer tooling 20 in the hot pressing area. This saves the time required for multiple material transfers in traditional designs and achieves seamless connection between "supply - picking up - loading".

[0051] In one embodiment of the present invention, please refer to Figure 1 and Figure 5 The hot pressing equipment also includes a correction component 80, which includes a first visual inspection element 81 and a second visual inspection element 82. The first visual inspection element 81 is located in the material feeding module 70, and the second visual inspection element 82 is located in the material feeding component. The first visual inspection element 81 is configured to acquire the relative position information between the material feeding component and the hot pressing material, and the second visual inspection element 82 is configured to acquire the relative position information between the hot pressing material and the workpiece.

[0052] In this embodiment, the first visual detection element 81 and the second visual detection element 82 are industrial CCD cameras. The first visual detection element 81 is located in the material feeding module 70, and its detection direction is away from the surface of the base 10. When the material feeding assembly absorbs the hot-pressed material from the material feeding module 70, the detection end of the first visual detection element 81 can directly face the air nozzle of the material feeding assembly, thereby obtaining the relative position information between the air nozzle of the material feeding assembly and the hot-pressed material. This detection information is then fed back to the control unit to determine the positional accuracy between the air nozzle and the hot-pressed material. For example, when the control unit determines that the positional accuracy between the air nozzle and the hot-pressed material exceeds a preset deviation, the control system can control the movement of the XY-axis two-dimensional linear guide rail to change the position of the hot-pressed material, ensuring the relative position between the air nozzle and the hot-pressed material. At the same time, the control unit sends a discard signal to the material feeding assembly, and the material feeding assembly deflates according to the discard signal. This allows the hot-pressed material already located at the air nozzle to fall off the air nozzle and be re-adsorbed with new hot-pressed material. The second vision detection element 82 is located on the material feeding assembly and moves together with the material feeding assembly. The detection direction of the second vision detection element 82 is towards the surface of the base 10. After the material feeding assembly places the hot-pressed material onto the workpiece, the detection end of the second vision detection element 82 can directly face the workpiece, thereby obtaining the relative position information between the workpiece and the hot-pressed material. This detection information is then fed back to the control unit to determine the positional accuracy between the workpiece and the hot-pressed material. For example, when the control unit determines that the positional accuracy between the workpiece and the hot-pressed material exceeds the preset deviation, the control system controls the air nozzle of the material feeding assembly to suck up the hot-pressed material located on the workpiece, and at the same time controls the movement of the movers of the material handling unit 33 and the hot-pressing moving unit 34, thereby adjusting the position of the workpiece and the air nozzle to ensure that the positional accuracy between the workpiece and the hot-pressed material is within the preset deviation. Through the coordinated work of the first vision inspection component 81 and the second vision inspection component 82, the correction component 80 realizes visual closed-loop control of the entire process of "material picking-discharging", effectively eliminating the cumulative error caused by material position deviation, mechanical vibration or tooling positioning error, ensuring the relative position accuracy of hot-pressed materials and workpieces, and guaranteeing the yield of hot-pressed products.

[0053] In one embodiment of the present invention, please refer to Figure 4 The hot pressing equipment also includes a lifting mechanism 90, which is located at the end of the loading and unloading conveying unit 31 near the material handling unit 33; the lifting mechanism 90 is configured to lift the transfer tooling 20.

[0054] In this embodiment, the lifting mechanism 90 includes a drive component, a lifting platform, and a positioning auxiliary component. The drive component uses a servo electric cylinder or a dual-cylinder synchronous drive. The cylinder body of the electric cylinder / cylinder is fixed on the base 10 support below the loading and unloading conveying unit 31. The top of the piston rod is rigidly connected to the lifting platform, and the lifting stroke can be precisely controlled by the control system. The lifting platform is a load-bearing structure, and the platform size is adapted to the bottom of the transfer tooling 20. The platform surface is provided with anti-slip textures or elastic buffer pads to prevent the tooling from sliding during lifting and to avoid hard contact damage to the tooling. The positioning auxiliary component includes 2-4 positioning pins or guide blocks, which are evenly distributed on the edge of the lifting platform platform. The position of the positioning pin corresponds to the positioning hole on the transfer tooling 20. The inner side of the guide block is provided with an inclined guide surface to ensure that when the tooling is transported above the lifting platform, even if there is a slight deviation, it can be automatically corrected under the action of the guide surface, thereby improving the subsequent positioning accuracy.

[0055] When the transfer tooling 20 moves above the lifting platform along with the loading and unloading conveying unit 31, the drive component drives the lifting platform to rise, thereby lifting the transfer tooling 20. Subsequently, the gripper device of the workpiece handling unit 32 grabs the transfer tooling 20 for subsequent hot pressing. It can be understood that multiple transfer tools 20 can flow into one loading and unloading conveying unit 31 at the same time. When a transfer tooling 20 does not need to be hot pressed, the lifting mechanism 90 lifts the transfer tooling 20 in front, providing passage space for the transfer tooling 20 that does not need to be hot pressed later. At this time, the transfer tooling 20 that does not need to be hot pressed later can flow out along the loading and unloading conveying unit 31 for unloading or the next production work.

[0056] The present invention also proposes a production bus, which includes a hot pressing device as described above. Specifically, the production bus includes a hot pressing device, a dispensing device, a workpiece assembly device, etc. By using an automated production bus, efficient and precise assembly can be achieved. The specific structure of the hot pressing device is as described in the above embodiments. Since the production bus proposed in this invention adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0057] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
