Description

TECHNICAL FIELD

[0001] The present application relates to the field of automation processing technology, in particular to a hot pressing equipment and a production bus. BACKGROUND

[0002] With the continuous development of automation technology, hot pressing process has become a key process widely used in product assembly links together with attaching, dispensing, screwing, hot melting and other processes. In the production process of various products, these processes jointly bear the important role of improving the stability and functionality of product assembly. Among them, the hot pressing process is constantly extending to electronic, hardware, plastic and other sub-industries due to its special protection capability for connection strength and bonding accuracy, and the universality of use is significantly improved.

[0003] In related hot pressing technology, in order to avoid the influence of back glue on hot pressing effect, back glue cannot be used to pre-fix the hot pressing material in the process link, which leads to the fact that the relative position between the hot pressing material and the product cannot be fixed during the time when the hot pressing material and the product are moved to the hot pressing station after assembly. In this process, factors such as start-stop inertia and flatness of the moving path will cause relative displacement between the two, resulting in hot pressing deviation problem.

[0004] Therefore, in order to avoid the hot pressing deviation problem, the current hot pressing equipment is a semi-automatic equipment. In the hot pressing process, the operator needs to manually place the hot pressing material accurately on the product, and then the hot pressing mechanism of the equipment completes the pressing action, finally realizing hot pressing processing. Although this ensures the hot pressing accuracy, it is not conducive to the improvement of production efficiency. SUMMARY

[0052] The main purpose of the present application is to provide a hot pressing equipment, which aims to ensure the relative position between the hot pressing material and the workpiece by automatic means, and to improve the production efficiency while ensuring the hot pressing accuracy.

[0053] To achieve the above purpose, the hot pressing equipment is used for hot pressing the hot pressing material and the workpiece, please refer to Figure 1 , the hot pressing equipment includes a base 10, the base 10 is provided with a flow transfer tool 20, a flow transfer module 30, a material feeding assembly, a fixing assembly 50 and a hot pressing assembly 60; the flow transfer tool 20 is movably arranged in the flow transfer module 30, and the flow transfer tool 20 is configured to carry the workpiece; the material feeding assembly is configured to place the hot pressing material on the workpiece located in the flow transfer tool 20; the fixing assembly 50 is configured to fix the relative position between the hot pressing material and the workpiece located in the flow transfer tool 20, the fixing assembly 50 includes a fixing driving part 51 and a fixing action part 52, the fixing action part 52 is connected with the fixing driving part 51, the hot pressing assembly 60 has a transfer tool 61 movably arranged, and the end of the fixing action part 52 is inserted into the transfer tool 61; the hot pressing assembly 60 is configured to hot press the hot pressing material and the workpiece located in the flow transfer tool 20; the hot pressing equipment has a pre-hot pressing state, in the pre-hot pressing state, the transfer tool 61 is limitedly matched with the flow transfer tool 20, and the end of the fixing action part 52 away from the transfer tool 61 is inserted into the flow transfer tool 20.

[0054] Specifically, the base 10 is the overall support structure of the hot-pressing equipment, usually made of high-strength metal materials such as cast steel, aluminum alloy, etc., and has a structure in the form of a "flat plate or frame". The top surface thereof is precisely milled to ensure flatness, for stably mounting the flow module 30, the material loading assembly, the fixing assembly 50, and the hot-pressing assembly 60; the inside of the base 10 is also reserved with cable slots and air pipe channels for accommodating the electrical control lines and pneumatic pipelines of the equipment, to prevent external interference from affecting the running stability of the components. The base 10 also has a control system, which is integrated in the inside or side of the base 10, the core of which is a programmable logic controller (PLC) or an industrial computer (IPC), and is equipped with corresponding motion control cards, temperature control modules, and I / O modules. The control system communicates with each execution component and sensor of the equipment through industrial Ethernet or field bus (such as Profinet, EtherCAT), and uniformly coordinates and sequentially controls the automatic operation of the entire hot-pressing process.

[0055] The flow tooling 20 is used to carry the workpieces in each component. In an embodiment, the workpieces are flat plates, such as the housings of smart devices such as mobile phones and small speakers. The surface of the flow tooling 20 is provided with shallow grooves matching the size of the workpieces, and the inner wall of the grooves is pasted with anti-slip silica gel pads. In this way, when the workpieces and the flow tooling 20 flow in the base 10, the workpieces can be prevented from moving relative to the flow tooling 20, and the hot-pressing error caused by the movement of the workpieces in the subsequent hot-pressing work can be avoided. In another embodiment, each workpiece has a through hole, and the flow tooling 20 is provided with a matching hole matched with the through hole of the workpiece. When the workpiece is placed on the surface of the flow tooling 20, the through hole corresponds to the matching hole. In this way, the fixing assembly 50 can adopt a vacuum adsorption method or a magnetic attraction fixing method. The negative pressure action or the magnetic attraction action can occur in the hot-pressing flow through the matching hole and the through hole in turn, so as to realize the position fixing between the workpiece and the hot-pressing material.

[0056] The flow transfer module 30 is used to realize the flow transfer of the flow transfer tool 20 on the base 10, and the flow transfer module 30 comprises one or more of a conveying belt, a linear rail, a mechanical hand and the like in combination. In an embodiment, the flow transfer module 30 comprises a conveying belt and three linear rails. For the purpose of clear explanation, the three linear rails are defined as a first linear rail, a second linear rail and a third linear rail. The first linear rail and the second linear rail both have a mover moving along the guide rail. The mover of the first linear rail is provided with a jaw device, which comprises a plurality of driving members and a plurality of jaws capable of opening and closing. The driving members can be servo motors or servo cylinders. The driving members are controlled to work by a control system, so as to drive the jaws to move towards and away from the flow transfer work and to open and close the plurality of jaws, thereby realizing the clamping and fixing of the flow transfer tool 20. The mover of the second linear rail is provided with a vacuum suction device, and the air nozzle of the vacuum suction device is used to suck the hot-pressing material. Specifically, the flow transfer tool 20 with the workpiece is moved to a position close to the first linear rail by the conveying belt, and then the jaw device moves to the upper side of the flow transfer tool 20 along the mover. Under the driving of the plurality of driving members, the jaws move downward to clamp the flow transfer tool 20, and then the flow transfer tool 20 is placed on the third linear rail. The flow transfer work moves to a position close to the second linear rail through the third linear rail. The vacuum suction device of the second linear rail places the hot-pressing material on the workpiece of the flow transfer tool 20, and then the hot-pressing material is fixed and hot-pressed. In another embodiment, the flow transfer module 30 comprises a conveying belt, one linear rail and two mechanical hands. The conveying belt is used to flow the flow transfer tool 20, and then one mechanical hand places the flow transfer tool 20 on the linear rail. The flow transfer tool 20 moves along the linear rail to a position close to the other mechanical hand. The other mechanical hand places the hot-pressing material on the flow transfer tool 20 by using a clamping, vacuum suction, electrostatic suction or the like, and then the hot-pressing material is fixed and hot-pressed.

[0057] The material feeding assembly 40 is an automatic structure for accurately placing the hot-pressing material in the form of a heat-conducting sheet, a metal connecting sheet or the like on the workpiece. In an embodiment, the material feeding assembly comprises a material storage unit and a material transfer unit. The material storage unit is a vibrating disc, and the material transfer unit is provided with a vacuum suction device, which comprises a vacuum generator, a vacuum suction disc and a lifting cylinder. The hot-pressing material on the vibrating disc is sucked by the suction disc under negative pressure. The suction force can be adjusted by a vacuum valve to avoid damaging the hot-pressing material. In another embodiment, the material transfer unit comprises a pneumatic finger, a jaw arm and a non-slip pad. The jaw arm can adjust the opening and closing width according to the size of the material, and is suitable for grabbing hard and non-deformable materials such as metal sheets. The hot-pressing material is placed on the workpiece in the flow transfer tool 20 by clamping, so as to realize the assembly of the hot-pressing material and the flow transfer tool 20.

[0058] The fixing assembly 50 is the core structure for fixing the relative position of the hot-pressing material and the workpiece. In an embodiment, the fixing assembly 50 is composed of a support, a lifting cylinder and a pressure head. The support is fixed above the base 10, the piston rod of the lifting cylinder is connected to the pressure head, and the pressure head is made of high-temperature-resistant resin to avoid scratching the material. When the transfer tool 20 is in place, the cylinder drives the pressure head to descend and press the material tightly on the surface of the workpiece. The pressing force can be controlled by a pressure regulating valve to ensure firm fixation without damaging the material / workpiece. In another embodiment, in order to adapt to the workpiece with a through hole, the fixing assembly 50 is composed of a vacuum generator, an air pipe and an air nozzle. The transfer tool 20 is provided with a matching hole, and the matching hole is arranged opposite to the through hole. One end of the air pipe is connected to the vacuum generator, and the other end corresponds to the matching hole of the transfer tool 20. When the material is placed on the workpiece, the vacuum generator is started to generate negative pressure through the air pipe to adsorb the material on the surface of the workpiece, realizing non-contact fixation with the hot-pressing material.

[0059] The hot-pressing assembly 60 is the execution structure for realizing the hot-pressing connection of the hot-pressing material and the workpiece, which is composed 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 is built-in with a heating rod, and the hot-pressing head is made of copper alloy with high heat conduction efficiency and is plated with nickel on the surface for oxidation prevention treatment. The temperature control module can set the temperature according to the process requirements and feedback in real time through the temperature sensor to realize closed-loop temperature control. The pressure unit is driven by a servo motor or a cylinder, and the hot-pressing head is lowered by a ball screw or a piston rod to apply hot-pressing pressure. The pressure accuracy can be adjusted by feedback of a pressure sensor. A guide sleeve is arranged below the hot-pressing head to cooperate with the positioning pin on the transfer tool 20 to ensure accurate alignment of the material when the hot-pressing head is lowered.

[0060] In order to facilitate the feeding of the hot-pressing material, the discharge of the hot-pressing material and the hot-pressing action, the transfer module 30 at least has a workpiece carrying station, a material feeding station and a hot-pressing station. In the workpiece carrying station, the transfer tool 20 with the workpiece and without the hot-pressing material completes the first transfer. In the material feeding station, the hot-pressing material is placed on the workpiece by the material feeding assembly. When the hot-pressing material and the workpiece are assembled, the fixing assembly 50 is started to keep the relative position between the hot-pressing material and the workpiece fixed during the process from the material feeding station to the hot-pressing station, thereby avoiding the relative deviation between the hot-pressing material and the workpiece before hot-pressing.

[0061] In the technical solution, the flow transfer tool 20 is movably arranged on the flow transfer module 30 and used for carrying the workpiece, the material loading assembly can automatically place the hot pressing material on the workpiece on the flow transfer tool 20, thereby replacing manual loading and solving the problem of manual placement of the semi-automatic equipment; secondly, the fixing assembly 50 can fix the relative position of the hot pressing material and the workpiece on the flow transfer tool 20, which solves the problem of relative displacement in the flow transfer process caused by the pre-fixing without adhesive. After the material loading assembly completes the placement of the hot pressing material, the fixing assembly 50 can timely lock the positions of the hot pressing material and the workpiece, thereby avoiding the relative displacement caused by factors such as start-stop inertia and path flatness when the flow transfer module 30 drives the flow transfer tool 20 to move, and ensuring the accurate positions of the hot pressing material and the workpiece before hot pressing; finally, the hot pressing assembly 60 can hot press the hot pressing material and the workpiece with fixed positions on the flow transfer tool 20, and the entire process from workpiece carrying, hot pressing material loading, position fixing to hot pressing is automatically completed by the equipment without manual intervention. In this way, the fixing assembly 50 effectively fixes the relative positions of the hot pressing material and the workpiece, completely solves the problem of relative displacement in the flow transfer process, ensures the hot pressing accuracy, avoids hot pressing deviation, and in the process, the fixing assembly 50 replaces manual operation, greatly reduces the manual participation link, significantly improves the production efficiency, avoids the errors caused by manual operation, and further improves the stability and consistency of hot pressing processing.

[0062] Further, referring to Figure 2 and Figure 3 , the fixing assembly 50 includes a fixing driving member 51 and a fixing acting part 52, the fixing acting part 52 is connected to the fixing driving member 51, the hot pressing assembly 60 has a transfer tool 61 movably arranged, and the end of the fixing acting part 52 is inserted into the transfer tool 61; the hot pressing equipment has a pre-hot pressing state, in the pre-hot pressing state, the transfer tool 61 is limitedly matched with the flow transfer tool 20, and the end of the fixing acting part 52 is inserted into the flow transfer tool 20.

[0063] In the embodiment, the fixing assembly 50 is integrally arranged with the hot-pressing assembly 60, so that the fixing part 52 can be close to the adapter tool 61 of the hot-pressing assembly 60, the adapter tool 61 is used for matching the output end of the fixing part 52, the output end of the fixing part 52 is limited in the adapter tool, so that the fixing part 52 can directly act on the hot-pressing material in the preheating and pressing state, so that the relative position between the hot-pressing material and the workpiece can be fixed; specifically, the adapter tool 61 is provided with a plurality of positioning pins, the transfer tool 20 is provided with positioning holes matched with the positioning pins, the transfer module 30 places the transfer tool 20 on the adapter tool 61, and then the transfer tool 20 moves to the material loading station and the hot-pressing station with the adapter tool 61. By means of the adapter tool 61, the end of the fixing part 52 can be inserted and limited in the adapter tool 61, so that the end of the fixing part 52 and the adapter tool 61 are always in a fixed state during the working process of the hot-pressing equipment, so that when the adapter tool 61 and the transfer tool 20 are assembled, the fixing part 52 of the fixing assembly 50 can directly act on the hot-pressing material, the relative position between the hot-pressing material and the workpiece is fixed, and thus it is not necessary to fix the fixing assembly 50 and the transfer tool 20 every time the hot-pressing material and the workpiece are fixed, so that the working efficiency of the hot-pressing equipment is improved.

[0064] In an embodiment of the present application, referring to Figure 2 and Figure 3 , the adapter tool 61 is provided with a first matching hole, the transfer tool 20 is provided with a second matching hole, and the fixing part 52 is limited in the first matching hole and corresponds to the second matching hole.

[0065] In the embodiment, the first matching hole is a linear straight hole penetrating from the bottom surface of the adapter tool 61 to the top surface of the adapter tool 61, the first matching hole is matched with the second matching hole, and the fixing part 52 is limited in the first matching hole. When the hot-pressing material is a magnetic metal piece such as a stainless steel connecting piece or an iron heat-conducting piece, the fixing assembly 50 can adopt a magnetic attraction mode. Specifically, the fixing driving part 51 of the fixing assembly 50 is a servo electric cylinder, and the fixing part 52 is a magnetic attraction head with an embedded electromagnetic coil. The coil adopts a high-temperature-resistant enameled wire to avoid the influence of hot-pressing heat, and the end of the magnetic attraction head is provided with a circular adsorption surface. In operation, when the material feeding assembly accurately places the magnetic metal piece hot-pressing material on the preset position of the workpiece on the flow tool 20 by vacuum adsorption or clamping, the control system receives the “positioning qualified” signal fed back by the positioning detection sensor (such as an optical fiber sensor) on the adapter tool 61, and then drives the fixing driving part 51 to insert the magnetic attraction head into the first matching hole from the bottom surface of the adapter tool. The magnetic attraction head uniformly rises along the linear straight hole, sequentially passes through the first matching hole and the second matching hole, and then the adsorption surface is in close contact with the surface of the hot-pressing material. The control system immediately supplies power to the electromagnetic coil of the magnetic attraction head, outputs a set current according to the parameters of the hot-pressing material, generates a stable magnetic field, and firmly adsorbs the hot-pressing material on the surface of the workpiece, so as to fix the relative positions of the two. In the process of moving the flow tool 20 with the adapter tool 61 from the material feeding station to the hot-pressing station, the fixing assembly 50 remains in the magnetic attraction state, the magnetic attraction head is always limited on the surface of the hot-pressing material through the first matching hole and the second matching hole, and the relative displacement problem caused by start-stop inertia and path flatness in the traditional design without fixing is completely avoided. When reaching the hot-pressing station, the fixing assembly 50 stops working, the hot-pressing head of the hot-pressing assembly 60 accurately aligns with the hot-pressing material under the cooperation of the guide sleeve and the positioning pin on the flow tool 20, and then hot-pressing is performed. After hot-pressing is completed, the flow module 30 moves the flow tool 20 out of the hot-pressing station, and one cycle of automatic hot-pressing is completed.

[0066] By using the first matching hole of the adapter tool 61, for different sizes of magnetic metal piece hot-pressing materials, only the magnetic attraction head and the bushing with a straight hole diameter need to be replaced, without the need to modify the main structure of the adapter tool 61, so as to improve the universality of the equipment. The linear straight hole design supports rapid retooling, finally realizes the core target of “automatic accurate fixing-high efficiency hot-pressing-low maintenance cost”, ensures hot-pressing accuracy, and significantly improves production efficiency.

[0067] In an embodiment of the present application, please refer to Figure 2 and Figure 3 , the fixing driving part 51 is a vacuum adsorption pump, the end of the fixing part 52 away from the vacuum adsorption pump is provided with an air nozzle, and the air nozzle is inserted into the first matching hole.

[0068] In the pre-hot-pressing state, the air nozzle extends to the second matching hole.

[0069] In the embodiment, as shown in Figure 2 and Figure 3 The first matching hole of the adapter tool 61 is an "L" shaped hole, which forms an insertion port on the side of the adapter tool 61 and an insertion exit port on the top of the adapter tool 61. The fixed part 52 passes through the insertion port and the insertion exit port in sequence and enters the second matching hole to fix the relative position of the hot-pressing material and the workpiece. When the hot-pressing material has a through hole, the fixed part 52 is a vacuum suction 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 driving part 51, is limited in the insertion exit port of the first matching hole, and partially protrudes from the top of the adapter tool 61. When the flow tool 20 and the adapter tool 61 are assembled, the air nozzle is embedded in the second matching hole, and a vacuum suction pump is started to generate negative pressure. The suction force is transmitted to the air nozzle through the air pipe and finally acts on the surface of the hot-pressing material through the through hole on the hot-pressing material, so that the hot-pressing material is stably adsorbed and fixed on the workpiece without physical contact, and the displacement of the hot-pressing material in the subsequent flow and hot-pressing process is prevented.

[0070] In an embodiment of the present application, please refer to Figure 4 The fixed assembly 50 further comprises a support plate 53, which is arranged on the flow module 30, and the adapter tool 61 is limited in cooperation with the support plate 53.

[0071] In the embodiment, the support plate 53 is arranged on the flow transfer module 30 and moves back and forth among the workpiece carrying station, the material loading station and the hot-pressing station with the work of the flow transfer module 30; specifically, the surface of the support plate 53 is provided with a limiting structure matched with the adapter tooling 61, such as a positioning groove, a protruding positioning block or a positioning pin, etc., when the adapter tooling 61 is placed on the support plate 53, the two are precisely clamped through the limiting structure, avoiding the adapter tooling 61 from deviating or shaking due to vibration or inertia during the movement of the flow transfer module 30; this limiting and matching design provides a stable bearing basis for the adapter tooling 61 on the one hand, ensuring that the first matching hole of the adapter tooling 61 can always be accurately aligned with the second matching hole of the subsequent assembled flow tooling 20, so that the fixed action part 52 (such as an air nozzle or a magnetic suction head) of the fixing assembly 50 can be smoothly inserted and act on the hot-pressed material, without the need for additional adjustment of the hole position alignment; on the other hand, when the flow transfer module 30 drives the support plate 53, the adapter tooling 61 and the flow tooling 20 to form an overall switching station, the support plate 53 can buffer the impact generated by the movement of the flow transfer module 30, reduce the relative displacement risk of the adapter tooling 61 and the flow tooling 20, and the fixed action part 52, and further protect the relative position accuracy of the hot-pressed material and the workpiece; at the same time, the existence of the support plate 53 also indirectly optimizes the installation and maintenance convenience of the adapter tooling 61 - when different specifications of the adapter tooling 61 need to be replaced, the old tooling can be removed by only releasing the limiting and matching of the support plate 53 and the adapter tooling 61, without the need to disassemble the flow transfer module 30 or the fixing assembly 50, the operation is more convenient, and the support plate 53 can protect the adapter tooling 61 from direct rigid contact with the flow transfer module 30, thereby prolonging the service life of the adapter tooling 61; ultimately, through the limiting and matching of the "support plate 53-adapter tooling 61", more stable structural support is provided for the full-process automation of the hot-pressing equipment from the workpiece carrying, material loading to hot-pressing, helping to improve the operation reliability while ensuring the accuracy.

[0072] In an embodiment of the present application, please refer to Figure 4 , Figure 5 and Figure 6 , the flow transfer module 30 includes a loading and unloading conveying unit 31, a workpiece carrying unit 32, a material carrying unit 33 and a hot-pressing moving unit 34; the material loading assembly is movably arranged in the material carrying unit 33, the hot-pressing assembly 60 and the adapter tooling are arranged in the hot-pressing moving unit 34; the workpiece carrying unit 32 is configured to carry the flow tooling 20 to flow between the hot-pressing moving unit 34 and the loading and unloading conveying unit 31.

[0073] In the embodiment, the feeding and discharging conveying unit 31 is composed of two parallel conveying belts. For the convenience of explanation, the two conveying belts are defined as a first conveying belt and a second conveying belt. The conveying directions of the first conveying belt and the second conveying belt can be the same or opposite. For example, when the conveying directions of the first conveying belt and the second conveying belt are the same, the two conveying belts can alternately convey the flow-through tooling 20, thereby reducing the waiting time of the material conveying unit 33. When the conveying directions of the first conveying belt and the second conveying belt are the same, the first conveying belt is used to provide the un-hot-pressed flow-through tooling 20 for feeding, and the second conveying belt is used to provide the hot-pressed flow-through tooling 20 for discharging. Different conveying belts are used to complete different process actions, thereby improving the feeding and discharging flow-through efficiency.

[0074] The workpiece conveying unit 32 includes a linear guide rail and a workpiece conveying device. The workpiece conveying device is arranged on the mover of the linear guide rail and moves back and forth between the feeding and discharging conveying unit 31 and the hot-pressing moving unit 34, so as to accurately convey the flow-through tooling 20 with the workpiece on the feeding and discharging conveying unit 31 to the adapter tooling 61 of the hot-pressing moving unit 34. After the hot pressing is completed, the flow-through tooling 20 with the finished product is conveyed from the adapter tooling 61 back to the discharging end of the feeding and discharging conveying unit 31. The workpiece conveying device is of a gripper type structure and at least includes a first driving member for controlling the lifting of the gripper and a second driving member for controlling the opening and closing of the gripper. Through the cooperation of the two driving members, the workpiece conveying unit 32 can realize the flow-through of the flow-through tooling 20 between different stations.

[0075] The material conveying unit 33 is an X-Y axis linear module. The material feeding assembly 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 above the adapter tooling 61 of the hot-pressing moving unit 34. When the workpiece conveying unit 32 completes the advance assembly of the flow-through tooling 20 and the adapter tooling 61, the vacuum adsorption transfer device has obtained the hot-pressing material from the hopper by the vacuum adsorption mode. When the flow-through tooling 20 moves towards the material conveying unit 33, the vacuum adsorption transfer device moves towards the adapter tooling 61 and finally moves above the flow-through tooling 20. In this process, the hot-pressing material (such as a flexible heat-conducting pad or a porous metal sheet) with through holes is accurately placed into the shallow groove on the top surface of the flow-through tooling 20 by the vacuum adsorption transfer unit, so as to ensure that the through holes of the material, the through holes of the workpiece and the second matching holes of the flow-through tooling 20 are aligned.

[0076] The hot-pressing moving unit 34 is a high-precision linear guide rail structure. The adapter tooling 61 is arranged on the guide rail. The adapter tooling 61 can reciprocally move between the workpiece conveying station, the material feeding station and the hot-pressing station. After the material feeding is completed, the hot-pressing moving unit 34 drives the adapter tooling 61 to move to the hot-pressing station. After the hot pressing is completed, the hot-pressing moving unit 34 returns to the workpiece conveying station to wait for the next cycle.

[0077] In a specific workflow, first, the feeding and discharging conveying unit 31 conveys the flow transfer tool 20 carrying only the workpiece to the feeding end, the clamping jaw of the workpiece carrying unit 32 grabs the flow transfer tool 20 and carries it to the adapter tool 61 of the hot-pressing moving unit 34, the pre-assembly of the double tool is completed, and the control system confirms the assembly qualification through the alignment sensor; then, the flow transfer tool 20 moves along the hot-pressing moving unit 34 towards the material carrying unit 33, then the material feeding assembly moves above the adapter tool 61, and the hot-pressing material is placed on the workpiece of the flow transfer tool 20, ensuring that the hot-pressing material is aligned with the workpiece; then, the vacuum suction pump of the fixing assembly 50 is started to work, so that the suction force generated by the air nozzle acts between the hot-pressing material and the workpiece, ensuring that the relative position between the two is fixed; then, the hot-pressing moving unit 34 drives the adapter tool 61 and the flow transfer tool 20 to move to the hot-pressing station, when the hot-pressing head of the hot-pressing assembly 60 is accurately aligned with the material under 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 adapter tool 61 and the flow transfer tool 20 to move to the workpiece carrying station, and the workpiece carrying device of the workpiece carrying unit 32 carries the flow transfer tool 20 carrying the finished product to the discharging end of the feeding and discharging conveying unit 31, entering the next cycle.

[0078] In an embodiment of the present application, please refer to Figure 1 The workpiece carrying unit 32 is arranged close to the first side of the base 10, the material carrying unit 33 is arranged close to the second side of the base 10, and the feeding and discharging conveying unit 31 is arranged close to the third side of the base 10, the first side, the second side and the third side form a hot-pressing area, and the hot-pressing moving unit 34 is located in the hot-pressing area.

[0079] Among them, the first side and the second side are arranged on the base 10 in the first direction, and the third side is located on the same side of the first side and the second side on the base 10 in the second direction, and the first direction is perpendicular to the second direction.

[0080] In the embodiment, the first side and the second side are arranged in alignment along one direction of the base 10, and the third side is located on the same side as the two sides along the vertical direction. The middle hot pressing area enclosed by the three sides allows the workpiece carrying unit 32 and the material carrying unit 33 to operate from both ends of the base 10 to the middle hot pressing area, and the loading and unloading conveying unit 31 to realize the in-out of the tooling from the third side, and the operation paths of the units do not intersect with each other. The workpiece carrying unit 32 does not need to cross the operation range of the material carrying unit 33, and the material loading assembly also does not need to bypass the loading and unloading conveying path, completely avoiding the process jam caused by the intersection of each unit in the traditional layout, allowing the tooling carrying, material loading, hot pressing movement and other actions to be sequentially connected, and even some links can be prepared in parallel, greatly shortening the total time of a single process. At the same time, this layout concentrates the core hot pressing movement unit 34 in the middle of the base 10, and the units on the periphery are distributed compactly along the side, which not only avoids the space waste caused by the dispersed arrangement of sub-units, but also allows the hot pressing area to become the "center hub" of the operation of each unit. The actions of all sub-units are carried out around the hot pressing area, without the need for a long moving path, reducing the invalid time required for unit movement. At the same time, the operation space reserved outside the loading and unloading conveying unit 31 on the side not only facilitates personnel or automated equipment to carry out tooling loading and unloading, but also does not occupy the core operation area, allowing the entire device to maximize functionality within the limited base 10. Based on this layout, the workpiece carrying unit 32 carries the tooling from one side to the hot pressing area and assembles with the adapter tooling 61, and the material carrying unit 33 directly feeds the material to the assembled tooling from the other side, without the need for position adjustment to complete the feeding. The air nozzle of the fixing assembly 50 can easily insert into the L-shaped hole from the adaptive direction to realize fixation due to the sufficient space of the hot pressing area. The hot pressing movement unit 34 moves in the middle area to complete the hot pressing alignment. Each link realizes "seamless connection" due to the layout adaptation, without the need for additional adjustment of the unit position or waiting for other units to avoid, ensuring that the entire process from tooling feeding, material placement, fixation to hot pressing is carried out smoothly and automatically, effectively guaranteeing the relative position accuracy of the hot pressed material and the workpiece, and avoiding positioning deviation caused by chaotic dynamic line.

[0081] In an embodiment of the present application, please refer to Figure 1 and Figure 5 The hot pressing equipment further comprises a material feeding module 70, which is movably arranged at one end of the material carrying unit 33 away from the loading and unloading conveying unit 31.

[0082] The material feeding module 70 is configured to provide hot pressing material.

[0083] In the embodiment, the material feeding module 70 is a material feeder, which is matched with an X-Y two-dimensional linear guide rail, and has a feeding disc. The position of the feeding disc can be changed in real time through the movement of the X-Y two-dimensional linear guide rail, so that the position of the hot-pressing material relative to the material feeding assembly is adjusted, and the alignment accuracy between the material feeding assembly and the hot-pressing material is improved. The material feeding module 70 is movably arranged at one end of the material carrying unit 33 away from the feeding and discharging conveying unit 31, and is matched with the layout height of the three-side enclosure of the base to enclose the hot-pressing area, so as to further improve the automatic supply chain of the hot-pressing material. Based on the layout of each unit in the previous embodiment, the material feeding module 70 is arranged at one end of the material carrying unit 33 away from the feeding and discharging conveying unit 31, so as not to occupy the operation space of the feeding and discharging conveying unit 31 or interfere with the work path of the workpiece carrying unit 32. The feeding area, the core hot-pressing area and the tool loading and unloading area are clearly divided, so as to avoid the space conflict between the material supply and the tool circulation and the hot-pressing operation. Meanwhile, the material feeding module 70 can directly provide the hot-pressing material for the material feeding assembly on the material carrying unit 33, without the need of additionally adding a conveying structure. The material feeding assembly (such as a vacuum adsorption and transfer unit) can quickly take the material from the feeding module through the movement of the material carrying unit 33, and then directly transfer the material to the circulating tool 20 in the hot-pressing area, so as to save the time for multi-link transfer of the material in the traditional design, and realize the seamless connection of "material feeding-take material-feed material".

[0084] In an embodiment of the present application, referring to Figure 1 and Figure 5 , the hot-pressing equipment further comprises a deviation correction assembly 80, which comprises a first visual detection member 81 and a second visual detection member 82. The first visual detection member 81 is arranged on the material feeding module 70, and the second visual detection member 82 is arranged on the material feeding assembly. The first visual detection member 81 is configured to acquire the relative position information between the material feeding assembly and the hot-pressing material, and the second visual detection member 82 is configured to acquire the relative position information between the hot-pressing material and the workpiece.

[0085] In the embodiment, the first visual detection member 81 and the second visual detection member 82 are industrial CCD cameras, wherein the first visual detection member 81 is arranged on the material feeding module 70, and the detection direction of the first visual detection member 81 is away from the surface of the base 10; when the material loading assembly adsorbs the hot-pressing material from the material feeding module 70, the detection end of the first visual detection member 81 can directly face the air nozzle of the material loading assembly, so as to obtain the relative position information between the air nozzle of the material loading assembly and the hot-pressing material, and then feed the detection information to the control unit, so as to judge the position degree between the air nozzle and the hot-pressing material; for example, when the control unit judges that the position degree between the air nozzle and the hot-pressing material exceeds the preset deviation, the control system can control the X-Y two-dimensional linear guide rail to move, so as to change the position of the hot-pressing material, and ensure the relative position between the air nozzle and the hot-pressing material; at the same time, the control unit sends a discarding signal to the material loading assembly, and the material loading assembly deflates according to the discarding signal, so that the hot-pressing material on the air nozzle falls off the air nozzle, and a new hot-pressing material is adsorbed; the second visual detection member 82 is arranged on the material loading assembly and moves together with the material loading assembly, and the detection direction of the second visual detection member 82 is towards the surface of the base 10; after the material loading assembly places the hot-pressing material on the workpiece, the detection end of the second visual detection member 82 can directly face the workpiece, so as to obtain the relative position information between the workpiece and the hot-pressing material, and then feed the detection information to the control unit, so as to judge the position degree between the workpiece and the hot-pressing material; for example, when the control unit judges that the position degree between the workpiece and the hot-pressing material exceeds the preset deviation, the control system controls the air nozzle of the material loading assembly to adsorb the hot-pressing material on the workpiece, and controls the mover of the material carrying unit 33 and the hot-pressing moving unit 34 to move, so as to adjust the position of the workpiece and the position of the air nozzle, and ensure that the position degree between the workpiece and the hot-pressing material is within the preset deviation. Through the cooperation of the first visual detection member 81 and the second visual detection member 82, the deviation correction assembly 80 realizes the visual closed-loop control of the whole process of “material taking-material placing”, effectively eliminates the cumulative error caused by the material position deviation, mechanical vibration or tool positioning error, ensures the relative position accuracy of the hot-pressing material and the workpiece, and guarantees the hot-pressing yield.

[0086] In an embodiment of the present application, please refer to Figure 4 , the hot-pressing equipment further comprises a jacking mechanism 90 arranged at the end of the feeding and discharging conveying unit 31 close to the material carrying unit 33; the jacking mechanism 90 is configured to jack the flow turnover tool 20.

[0087] In the embodiment, the jacking mechanism 90 comprises a driving assembly, a lifting platform and a positioning auxiliary assembly. The driving assembly adopts a servo electric cylinder or a double-cylinder synchronous drive. The cylinder body of the electric cylinder / cylinder is fixed on the bracket of the base 10 below the feeding and discharging conveying unit 31. The top end of the piston rod is rigidly connected with the lifting platform, and the lifting stroke can be accurately controlled through the control system. The lifting platform is a bearing structure. The size of the platform surface is adapted to the bottom of the flow tool 20. The platform surface is provided with anti-skid lines or elastic buffer pads to prevent the tool from sliding during jacking and to avoid damage to the tool caused by hard contact. The positioning auxiliary assembly comprises 2-4 positioning pins or guide blocks, which are uniformly distributed on the edge of the lifting platform. The position of the positioning pin corresponds to the positioning hole on the flow tool 20. The inner side of the guide block is provided with an inclined guide surface to ensure that the tool is conveyed above the lifting platform. Even if there is slight deviation, it can be automatically corrected under the action of the guide surface, improving the subsequent positioning accuracy.

[0088] When the flow tool 20 moves above the lifting platform with the feeding and discharging conveying unit 31, the driving assembly drives the lifting platform to rise, thereby jacking up the flow tool 20. Then, the gripper device of the workpiece handling unit 32 grabs the flow tool 20 for subsequent hot pressing action. It can be understood that one feeding and discharging conveying unit 31 can simultaneously flow into multiple flow tools 20. When one flow tool 20 does not need to be hot-pressed, the preceding flow tool 20 is jacked up by the jacking mechanism 90 to provide a space for the flow tool 20 behind which does not need to be hot-pressed. At this time, the flow tool 20 behind which does not need to be hot-pressed can flow out along the feeding and discharging conveying unit 31 for discharging or the next production work.

[0089] The present application also proposes a production bus, which comprises the hot pressing equipment of any one of the above embodiments. Specifically, the production bus comprises hot pressing equipment, dispensing equipment, workpiece assembly equipment, etc. Through the use of an automated production bus, efficient and accurate assembly is carried out. The specific structure of the hot pressing equipment is referred to the above embodiments. Since the production bus proposed by the present application adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0090] The above is only the preferred embodiment of the present application, which does not limit the patent scope of the present application. Any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
