[0022] The present invention provides a hot pressing method, such as Figure 5As shown, the hot pressing device 100 is used to hot press materials, and the materials include auxiliary materials and sheet materials. The hot pressing device 100 includes a transmission system and a hot pressing system. The hot pressing system includes a preheating module 4 and a hot pressing module 5. It can be understood that the materials include auxiliary materials and sheet materials arranged in layers. The auxiliary materials and sheet materials have been pre-attached and combined before entering the hot pressing process. The materials are placed in a material tray for easy transportation. After the hot pressing process, the auxiliary materials and sheet materials are attached to each other as a whole.

[0023] Hot pressing methods include: S10: The transmission system loads the material to the preheating module 4, wherein the material includes the combined auxiliary material and the sheet material; In step S10, the transmission system automatically loads the material in the tray to the preheating module 4 to achieve automatic loading of the material, avoid manual intervention, and improve the loading efficiency of the material. Specifically, in order to facilitate the transportation of the material, the material is placed in the tray, and the transmission system loads the material in the tray to the preheating module 4.

[0024] S20: preheating the material through the preheating module 4, and the transmission system transmits the preheated material to the hot pressing module 5; In step S20, the preheating module 4 preheats the material to soften and activate the auxiliary material, so that the auxiliary material is easier to deform and fit on the surface of the material, which is convenient for the subsequent hot pressing treatment of the material. In this process, the preheating module 4 preheats the material according to the preheating temperature and preheating time. The preheating temperature and preheating time can be selected according to the material of the auxiliary material and the sheet material to ensure that the material maintains its original physical characteristics while the auxiliary material is softened and activated. After the material preheating is completed, the transmission system transmits the material to the hot pressing module 5 for hot pressing treatment.

[0025] S30: performing a hot pressing treatment on the preheated material through the hot pressing module 5, so that the auxiliary material and the sheet material of the material are closely attached; In step S30, the hot pressing module 5 reheats and presses the material reaching the hot pressing module 5. The reheating allows the auxiliary material to remain softened and activated during the pressing process, which facilitates pressing the auxiliary material and the sheet material.

[0026] S40: The transmission system unloads the material after the pressing process.

[0027] In step S40, the transmission system automatically unloads the hot-pressed material into the material tray to realize automatic unloading of the material, improve the unloading efficiency of the material, and facilitate the subsequent transportation of the material.

[0028] In this embodiment, after the preheating module 4 preheats the material, the hot pressing module 5 hot presses the material, which can improve the uniformity of the material's heating, reduce the stress inside the material, and avoid damage to the material during the hot pressing process. At the same time, the preheating module 4 and the hot pressing module 5 can operate synchronously, which effectively shortens the hot pressing processing time and improves the hot pressing efficiency. During the entire hot pressing process, the transmission system loads, transmits and unloads the material to realize the assembly line production of the hot pressing process of the material, reduce the manual participation in the hot pressing process, effectively improve the material transportation speed, and improve the efficiency of the hot pressing process.

[0029] In one embodiment of the present invention, the hot pressing module 5 includes a fixing portion 51, an adjusting portion and a pressing head 54. In step S30, the hot pressing module 5 includes: S31: fixing the position of the material by the fixing part 51 and heating the material; Specifically, the transmission system transmits the preheated material to the fixing portion 51 , and the fixing portion 51 positions the material and fixes the position of the material to prevent the material from changing its position in the fixing portion 51 , so as to facilitate subsequent pressing of the material.

[0030] S32: the adjusting unit adjusts the relative position of the material and the pressing head 54 until the pressing head 54 and the material are aligned in the vertical direction, and drives the pressing head 54 to press the material; Specifically, the adjustment unit adjusts the relative position of the material and the pressing head 54 according to the relative three-dimensional position information of the material and the pressing head 54, and at the same time, adjusts the angle between the material and the projection of the pressing head 54 in the vertical direction, so that the pressing head 54 and the part of the material to be pressed are completely aligned in the vertical direction, and the pressing head 54 presses the material in the vertical direction. The pressing head 54 is driven to descend to a preset distance from the material, so that the material enters the pressing stroke of the pressing head 54, and the pressing head 54 is driven to press the auxiliary material downward, so that the auxiliary material and the sheet material are closely fitted.

[0031] S33: driving the pressing head 54 upward to prepare for the next pressing.

[0032] Specifically, after the pressing head 54 has pressed for a preset time, the pressing head 54 is driven to rise to release the limit on the pressing head 54, and the fixing portion 51 also releases the position fixation of the material to facilitate the subsequent unloading of the material.

[0033] Optionally, the pressing head 54 has an initial position, and a three-dimensional coordinate is established based on the initial position. The adjusting part adjusts the relative position of the material and the pressing head 54 according to the coordinate of the fixing part 51 .

[0034] In one embodiment of the present invention, in step S20, it includes: under the condition that the material is detected to be transmitted to the preheating module 4, the material is preheated by the preheating module 4, and the preheated material is transmitted to the hot pressing module 5.

[0035] In this embodiment, the preheating module 4 creates a preheating space that maintains a certain temperature, and preheats the material by allowing the material to stay in the preheating space, and obtains the preheating time of the material according to the residence time of the material in the preheating space. Specifically, the transmission system transmits the material to the preheating module 4, and the preheating module 4 detects that the material stays in the preheating space, and counts the residence time of the material until the preheating time of the material reaches the preset preheating time, and the material completes the preheating treatment. After that, the transmission system transmits the material to the hot pressing module 5, so that the preheating time of the material can be accurately controlled, the accuracy of the material preheating treatment can be improved, and the activation quality of the auxiliary material can be effectively guaranteed. When the material stays in the preheating space for preheating treatment, the transmission system suspends the transmission of the material to the preheating module 4 and the transfer of the material from the preheating module 4. During operation, the preheating module 4 detects the temperature in the preheating space in real time. When the temperature in the preheating space exceeds the preset preheating temperature or is lower than the preset preheating temperature, the preheating module 4 issues an abnormal alarm, so as to timely troubleshoot and repair the preheating module 4 to avoid wasting materials.

[0036] The preheating module 4 detects the transmission of the material to the preheating module 4 through the first in-place detection member. The first in-place detection member can be a proximity sensor or a contact sensor, which can detect the in-place status and residence time of the material in the preheating space in real time.

[0037] In one embodiment of the present invention, the temperature of the preheating treatment is lower than the temperature of the hot pressing treatment, so that the material is heated in a stepwise manner in the preheating module 4 and the hot pressing module 5, further reducing the thermal stress inside the material and avoiding damage to the material during pressing.

[0038] Specifically, the temperature of the preheating treatment is the preheating temperature, and the temperature of the hot pressing treatment is the hot pressing temperature. The preheating temperature and the preheating time can be input in advance to the preheating module 4, and the preheating module 4 performs preheating treatment on the material according to the preheating temperature and the preheating time, and the hot pressing temperature and the hot pressing time are input to the hot pressing module 5, and the hot pressing module 5 performs hot pressing treatment on the material according to the hot pressing temperature and the hot pressing time. In actual applications, the preheating temperature and the hot pressing temperature can be initially set according to the properties of the product.

[0039] Optionally, the preheating module 4 and the hot pressing module 5 can respectively collect the temperature rise information of the material during the preheating process and the hot pressing process, and fit the temperature rise curve of the material according to the temperature rise information of the material, and adjust the preheating temperature and the hot pressing temperature by analyzing the temperature rise curve of the material, thereby optimizing the temperature rise curve of the material and improving the pressing quality of the material. In the process of optimizing the temperature rise curve, by combining the temperature rise situation and the characteristic changes of the material during the temperature rise, the optimal range of preheating parameters such as preheating temperature and preheating time and the optimal range of hot pressing parameters such as hot pressing temperature and hot pressing time can be obtained to obtain a better pressing effect.

[0040] In one embodiment of the present invention, the fixing part 51 includes a heating platform and a flattening mechanism. In step S31, the following steps are included: The heating platform carries and heats the material; The flattening mechanism cooperates with the heating platform to press the two ends of the material so as to flatten and fix the material.

[0041] In this embodiment, the transmission system transfers the preheated material to the heating platform. After the heating platform positions the material, the flattening mechanism presses the two ends of the material, so that the material that may be warped due to heat is flattened, ensuring the flatness of the material, avoiding affecting the subsequent pressing, and ensuring the quality of hot pressing. At the same time, the position of the material on the heating platform is fixed. The heating platform has a heating function, and the material is heated according to the preset hot pressing temperature and hot pressing time for subsequent pressing.

[0042] Specifically, the heating platform is provided with a second in-place detection member, which may be a proximity sensor or a contact sensor, and is used to detect the in-place information of the material on the heating platform. The flattening mechanism is provided with a lower pressure head corresponding to at least two ends of the material, and the flattening mechanism controls the lower pressure head to press down and flatten according to the in-place information of the material on the heating platform. When the second in-place detection member detects that the material has reached between the lower pressure head and the heating platform, the flattening mechanism drives the lower pressure head to flatten and press the material.

[0043] Optionally, the flattening mechanism can be two downward pressure cylinders, the downward pressure head is opposite to the heating platform and is arranged at an interval. After the material is transferred between the heating platform and the downward pressure head, the flattening mechanism obtains the material's arrival information, and the downward pressure cylinder drives the downward pressure head to press the two ends of the material to flatten and fix the material. After the transmission system transfers the material to the heating platform, the heating platform positions the material through the positioning cylinder. A positioning reference structure can be set on the heating platform. The positioning start completes the positioning of the material by pushing the material to fit the positioning reference structure.

[0044] In one embodiment of the present invention, the adjustment unit includes a rotating mechanism and a driving mechanism 53. In step S32, the following steps are included: The driving mechanism 53 drives the pressing head 54 to move above the material according to the relative position information between the material and the pressing head 54; The rotating mechanism rotates the heating platform according to the relative position information between the material and the pressing head 54 until the pressing head 54 and the material are aligned in the vertical direction; The pressing head 54 is driven to press the material.

[0045] It can be understood that the placement surface of the heating platform and the pressing surface of the pressing head 54 are set to be parallel to the XY plane, and the vertical direction is the Z-axis direction; before the pressing head 54 presses the material, it is necessary to adjust the relative positions of the material and the pressing head 54 in the X-axis direction and the Y-axis direction, and adjust the relative angle between the material and the pressing head 54 in the XY plane, so that the pressing head 54 and the part to be pressed of the material are completely aligned in the vertical direction.

[0046] In this embodiment, the driving mechanism 53 is used to drive the pressing head 54 along the X-axis and the Y-axis to adjust the position of the pressing head 54 in the X-axis direction and the Y-axis direction. The rotating mechanism is used to rotate the heating platform around the Z-axis direction to adjust the angle between the material on the heating platform and the pressing head 54 in the XY plane, thereby completing the vertical alignment of the material and the pressing head 54.

[0047] The adjustment part also includes a visual recognition mechanism arranged at the output end of the driving mechanism 53. The visual recognition mechanism moves with the pressure head 54. The visual recognition mechanism obtains the position information of the pressure head 54 in real time by identifying the identification information on the material, and obtains the relative position information of the pressure head 54 and the material in combination with its own position information. The driving mechanism 53 and the rotating mechanism adjust the relative position of the material and the pressure head 54 according to the relative position information of the material and the pressure head 54.

[0048] Optionally, the position of the heating platform is relatively fixed, and the rough position information of the heating platform can be obtained with the initial position of the pressure head 54 as a reference. The driving mechanism 53 can drive the pressure head 54 to move to the top of the heating platform according to the rough position information of the heating platform pre-input, and roughly align the material along the Z-axis direction. After that, the driving mechanism 53 and the rotating mechanism simultaneously fine-tune the relative position of the pressure head 54 and the material in the X-axis direction and the Y-axis direction and the relative angle in the XY plane according to the relative position information of the material and the pressure head 54 obtained in real time by the visual recognition mechanism, so as to ensure the alignment accuracy of the pressure head 54 and the material, facilitate the pressure head 54 to accurately press the material to the position to be pressed, and ensure the pressing quality.

[0049] The driving mechanism 53 also adjusts the relative distance between the pressing head 54 and the material in the vertical direction according to the relative position information of the pressing head 54 and the material; if a distance measuring mechanism is provided at the output end of the driving mechanism 53, the distance measuring mechanism moves with the pressing head 54 and obtains the relative distance between the pressing head 54 and the material in the Z-axis direction in real time, and the driving mechanism 53 drives the pressing head 54 down to a preset distance according to the relative distance information between the pressing head 54 and the material in Z; then the pressing head 54 driving member drives the pressing head 54 to press down to press the material, thereby achieving precise pressing of the material.

[0050] Optionally, the sheet material has a plurality of pits. After the auxiliary material and the sheet material are combined, the auxiliary material covers the top of the pits, and the auxiliary material is pressed into the pits by hot pressing so that the auxiliary material fits tightly with the inner wall of the pits. The pressing head 54 includes a plurality of pressing heads, and the plurality of pressing heads 54 need to be aligned with the plurality of pits in the vertical direction, respectively. The layout of the plurality of pressing heads 54 is consistent with the layout of the pits on the sheet material; the adjusting part aligns the pressing head 54 with the pits in the vertical direction, and after the distance between the pressing head 54 and the material is at a preset distance, the pressing head 54 driving member drives all the pressing heads 54 to press down to achieve the whole sheet pressing of the material. The pressing head 54 driving member can be a pressure-adjustable air source or a hydraulic device, and the pressure of the pressing head 54 can be adjusted according to the material of the material to achieve high-precision pressing of the material.

[0051] In one embodiment of the present invention, the hot pressing module 5 further includes a pressure detection unit 52, and in step S32, further includes: When the pressure detecting unit 52 detects that the pressure of the pressing head 54 meets the preset pressure, the adjusting unit adjusts the relative position of the material and the pressing head 54 until the pressing head 54 and the material are aligned, and drives the pressing head 54 to press the material.

[0052] In this embodiment, before the adjustment unit adjusts the relative position of the material and the pressure head 54, the pressure detection unit 52 detects the pressure of the pressure head 54 to ensure that the pressure head 54 is in a normal working state to avoid the pressure of the pressure head 54 being too high, causing the material to be crushed, or the pressure of the pressure head 54 being too low, causing the auxiliary material and the sheet material to be loosely pressed together.

[0053] Specifically, the position of the pressure detection part 52 is fixed, and the initial position of the pressure head 54 is used as a reference to obtain the position information of the pressure test part. The driving mechanism 53 of the pressure head 54 aligns the pressure detection part 52 in the vertical direction according to the position information of the pressure detection part 52. Then, the driving mechanism 53 of the pressure head 54 adjusts the relative distance between the pressure head 54 and the material to a preset distance in the vertical direction. The driving member of the pressure head 54 drives the pressure head 54 to press down with a preset pressure. The pressure detection part 52 detects the pressure value of the pressure head 54 and determines whether the pressure value of the pressure head 54 is within the preset pressure range. When the pressure detection part 52 detects that the pressure of the pressure head 54 does not meet the preset pressure, the hot pressing equipment 100 stops running and prompts the operator to promptly troubleshoot and repair the fault. The preset pressure can be set to different values ​​according to product requirements.

[0054] Optionally, when there are multiple pressing heads 54, the pressure detection unit 52 performs spot checks on the pressure of the pressing head 54 to avoid wasting work hours and ensure the consistency of the pressure of the pressing head 54. The pressure detection unit 52 does not need to perform pressure detection before each pressing of the pressing head 54. The interval time for the pressure detection unit 52 to perform pressure detection on the pressing head 54 can be input into the hot pressing module 5 in advance according to the needs, so that the pressure detection unit 52 performs pressure detection on the pressing head 54 regularly.

[0055] In one embodiment of the present invention, the hot pressing module 5 further includes a residual material detection unit 55, which includes: The pressing head 54 is driven to rise, and when the residual material detecting unit 55 detects that there is no material adhering to the pressing head 54 , the pressing head 54 is ready for the next pressing.

[0056] Specifically, after the pressing head 54 presses the material, the driving member of the pressing head 54 drives the pressing head 54 to move up and away from the material to release the material to facilitate the subsequent unloading of the material. The driving mechanism 53 drives the pressing head 54 to rise to avoid interfering with the transmission of the material by the transmission system; the driving mechanism 53 drives the pressing head 54 to rise and move to the residual material detection part 55. The residual material detection part 55 detects whether the pressing surface of the pressing head 54 carries up the material or has the material adhered to it to ensure the subsequent pressing quality.

[0057] Optionally, after the driving mechanism 53 drives the pressing head 54 to rise, the pressing head 54 is driven back to the initial position, and the residual material detection unit 55 is located below the initial position of the pressing head 54 to accurately detect the lower pressing surface of the pressing head 54, and after ensuring that there is no material residue on the lower pressing surface of the pressing head 54, the pressing head 54 is ready for the next pressing. If the residual material detection unit 55 detects that there is material residue on the pressing head 54, the operator is promptly warned to check to avoid affecting the quality of the next pressing.

[0058] Optionally, the pressing head 54 includes multiple ones, and the residual material detection unit 55 may include an actuator and an AOI camera. When the pressing head 54 returns to the initial position, the actuator drives the AOI camera pressing head 54 to move, so that the AOI camera performs an overall inspection of the pressing head 54.

[0059] In one embodiment of the present invention, the transmission system comprises a loading module 1 and a transfer module 2, the loading module 1 is provided with a first placement position 13, the first placement position 13 is used to place a material loading box, and a plurality of the materials are placed in layers in the material box; In step S10, it includes: S11: Under the condition that the pushing resistance of the material is detected to be within a preset range, the loading module 1 pushes the material out of the material box located at the first placement position 13 in sequence, and transfers the material to the transfer module 2 in sequence; S12: The transfer module 2 transfers the materials to the preheating module 4 in sequence.

[0060] Specifically, the two ends of the material box are set through, and multiple materials are placed in the material box in layers through the bracket. The material box can be transported by the AGV handling mechanism to improve the automation and intelligence of material loading. The loading module 1 includes a pushing part 11 and a loading track part 12. The pushing part 11 and the loading track part 12 are set at intervals. A first placement position 13 is formed between the pushing part 11 and the loading track part 12. The AGV handling mechanism directly moves into the first placement position 13, and the material box is placed in the first placement position 13. After that, the pushing part 11 is pushed in from one end of the material box, and the material falls into the loading track part 12 from the other end of the material box. The pushing end of the pushing part 11 is provided with a first resistance detection part. The first resistance detection part detects that the pushing resistance of the material meets the preset range. The pushing part 11 continues to push the material. The first resistance detection part detects that the pushing resistance of the material does not meet the preset range, and the pushing part 11 stops pushing the material to avoid bending of the material or even breaking during the loading process. It can be understood that during the loading process, the lifting device provided in the AGV transport mechanism or the first placement position 13 adjusts the height of the material box according to the position of the pushing part 11, so that the pushing part 11 can accurately push the materials in the material box in sequence.

[0061] Optionally, when a layer of material is loaded, the lifting device drives the material box to rise or fall so that the pusher 11 is aligned with the next material. According to the speed of loading and hot pressing, multiple loading modules 1 can be set for loading, thereby improving the processing efficiency of hot pressing. The conveying form of the loading track part 12 includes a conveyor belt or clamping transfer.

[0062] Specifically, the transfer module 2 includes a first transfer part 21, a first buffer part 22 and a transfer part 23. After the material is loaded onto the loading track part 12, the loading track part 12 transfers the material to the first transfer part 21 in sequence. After the material is transferred to the position to be transferred, the loading track part 12 suspends the transfer. After that, the first transfer part 21 transfers the material to the buffer part 22. The buffer part 22 is used to buffer the material to be preheated to avoid the material from directly piling up in the preheating module 4, which plays a buffering role. After that, the transfer part 23 transfers the material in the buffer part 22 to the preheating module 4. After the preheating module 4 preheats the material, the transfer part 23 also transfers the material from the preheating module 4 to the hot pressing module 5 for hot pressing. Among them, the first transfer part 21 takes the material by suction or clamping, and moves the material through the driving device.

[0063] It is understandable that the loading track portion 12 is provided with a third in-position detection member to detect whether the material has reached the position to be transferred. The first transfer portion 21 is provided with a first visual detection member to detect the position of the material, so as to facilitate the material to be taken, and the first visual detection member can also detect the characteristics of the material to determine whether the material is damaged.

[0064] Optionally, the transfer section 23 may include multiple sections to transfer materials between the first buffer section 22 and the preheating module 4 and between the preheating module 4 and the hot pressing module 5, respectively. The transfer section 23 may be in the form of a conveyor belt or a pushing cylinder, etc.

[0065] In one embodiment of the present invention, the transmission system further comprises a material unloading module 3, wherein the material unloading module 3 is provided with a second placement position 33, and the second placement position 33 is used to place an empty material box; In step S40, it includes: S41: the transfer module 2 transfers the material after the pressing process to a position close to the second placement position 33; S42: Under the condition that the pulling resistance of the material is detected to be within a preset range, the unloading module 3 sequentially pulls the material into the material box located at the second placement position 33 .

[0066] Specifically, the unloading module 3 includes a pulling portion 31 and a unloading track portion 32, and the transfer module 2 also includes a dividing portion 24 and a second transferring portion 25. The pulling portion 31 and the unloading track portion 32 are arranged at intervals, and a second placement position 33 is formed between the pulling portion 31 and the unloading track portion 32. The AGV handling mechanism can drive the empty material box to move into the second placement position 33 so that the empty material box is placed in the second placement position 33. The transfer portion 23 moves the material after hot pressing treatment from the hot pressing module 5 to the dividing portion 24, and the second transferring portion 25 transfers the material from the dividing portion 24 to the unloading track portion 32. The unloading track portion 32 transfers the material to a position close to the second placement position 33. Then, the pulling portion 31 passes through the material box and pulls the material on the unloading track portion 32 into the material box. The material enters the material box from one end of the material box to complete the unloading. The pulling end of the pulling part 31 is provided with a second resistance detection part. When the second resistance detection part detects that the pulling resistance of the material meets the preset range, the pulling part 31 continues to push the material. When the second resistance detection part detects that the pulling resistance of the material does not meet the preset range, the pulling part 31 stops pulling the material to avoid bending of the material or even breaking during the unloading process. It can be understood that during the unloading process, the lifting device provided in the AGV handling mechanism or the second placement position 33 adjusts the height of the material box according to the position of the pulling part 31, so that the pulling part 31 accurately pulls the material on the unloading track part 32 into the material box in sequence.

[0067] Optionally, after a material is discharged into the material box, the lifting device drives the material box to rise or fall, so that the pulling portion 31 is aligned with an empty position in the material box, so as to pass through the material box and pull the next material into the material box. According to the speed of the discharge, multiple discharge modules 3 can be set for discharge, thereby improving the processing efficiency of hot pressing. The conveying form of the discharge track portion 32 includes a conveyor belt or clamping transfer.

[0068] Specifically, when the loading module 1 and the unloading module 3 include multiple corresponding ones, after the material is transferred to the material dividing part 24 by the transfer part 23, the second transfer part 25 determines the material box of the material according to the mark on the material, so that the material loaded from the same material box is divided into the same unloading module 3, and then unloaded into the same material box, which is convenient for tracking the material in the production and transportation process and ensures the production quality of the material. The second transfer part 25 takes the material by suction or clamping, and moves the material through the driving device.

[0069] It is understandable that the unloading track portion 32 is provided with a fourth in-position detection member to detect whether the material has reached the unloading position. The second transfer portion 25 is provided with a second visual detection member to detect the position of the material, so as to facilitate the material to be taken out. At the same time, the second visual detection member can also detect the material characteristics and read the marking information on the material to determine whether the material is damaged and the material box to which the material belongs.

[0070] Optionally, the transfer section 23 may include multiple sections to transfer materials between the first buffer section 22 and the preheating module 4, between the preheating module 4 and the hot pressing module 5, and between the hot pressing module 5 and the material distribution section 24, and the transfer section 23 may be in the form of a conveyor belt or a pushing cylinder, etc.
