Description

Technical Field

[0001] The invention relates to the field of building boards, and in particular to a composite board production line. Background Art

[0002] At present, in the production of building panels, such as purification panels made of color-coated steel plates, aluminum plates or stainless steel as surface materials, multiple panels are usually combined on the production line through multiple processes. However, the existing production line has a low degree of mechanization and requires a large amount of manpower, which limits the production capacity of the production line. At the same time, after the multiple panels are bonded to each other through the glue spraying process, the cold pressing process is used in the final stage to cure the adhesive at room temperature for more than 8 hours to ensure that the multiple panels have sufficient bonding strength, resulting in low production efficiency. In addition, there is uneven adhesive adhesion in different areas between multiple panels, which makes the thickness of the final product have a large precision error in different areas, affecting the product yield.

[0053] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0054] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0055] See also Figures 1 to 31 An embodiment of the present application provides a composite board production line, including a first conveyor line A, a second conveyor line B, a third conveyor line C and a fourth conveyor line D, and each conveyor line can convey different materials through one or more conveyor lines respectively.

[0056] The first conveyor line A is provided with a first roller frame 61A, a loading station 10, a glue spraying processing area 20 and a plate area A1 to be assembled in sequence along the conveying direction. The first roller frame 61A is used to transport the first plate 71. The loading station 10 is arranged at the front end of the first conveyor line A, and multiple first plates 71 can be stacked around the front end. The loading station 10 is used to grab the first plate 71 to the first roller frame 61A. When the first conveyor line A transports the first plate 71 to the glue spraying processing area 20, the glue spraying processing area 20 can spray the adhesive 91 onto the surface of the first plate 71 to form a first processed plate. Finally, the first conveyor line A transports the first processed plate to the plate area A1 to be assembled at the end. At the same time, the plate area A1 to be assembled can be used for temporary storage of the first processed plate.

[0057] The second conveyor line B is provided with a second roller frame 61B, an assembly processing area B1 and a hot pressing processing area 50 in sequence along the conveying direction. Among them, the second roller frame 61B is used to transport the second plate 72, and the assembly processing area B1 of the second conveyor line B corresponds to the plate area A1 to be assembled of the first conveyor line A, and is used for the second plate 72 and the first processed plate to be combined into a second processed plate. For example, the second conveyor line B is arranged at intervals on one side of the first conveyor line A, and is parallel to the first conveyor line A, so that the assembly processing area B1 can correspond to one side of the plate area A1 to be assembled. In this way, the first processed plate on the first conveyor line A can be transported to the assembly processing area B1 of the second conveyor line B by manual means (such as flat dragging) to be combined with the second plate 72.

[0058] The third conveyor line C is provided with a third roller frame 61C, and the third roller frame 61C is connected to the assembly processing area B1 of the second conveyor line B, for conveying the third plate 73 to the assembly processing area B1, and can be combined with the first processing plate to form a third processing plate (that is, the combination of the first plate 71, the second plate 72 and the third plate 73). For example, the third conveyor line C is arranged relatively above the second conveyor line B, and is connected to the assembly processing area B1 of the second conveyor line B from top to bottom. Such a configuration helps to effectively reduce the space occupied by the conveyor line without affecting the conveyance of the plate.

[0059] The fourth conveyor line D is provided with a fourth roller frame 61D for conveying the fourth plate 74, and the fourth conveyor line D is provided with a plate turning station D1 at a position corresponding to the assembly processing area B1 of the second conveyor line B. Among them, the plate turning station D1 is used to convey, receive and transmit the fourth plate 74 to the assembly processing area B1 of the second conveyor line B, and can be combined with the third plate 73 to form a composite plate 80 (that is, a combination of the first plate 71, the second plate 72, the third plate 73 and the fourth plate 74). In this embodiment, the fourth conveyor line D is arranged at intervals on the other side of the second conveyor line B relative to the first conveyor line A, so that the first conveyor line A, the second conveyor line B and the fourth conveyor line D are parallel to each other, and the corresponding plates are conveyed respectively along the first axial direction Y. However, the embodiment of the present application is not limited to this. In practice, the first conveyor line A, the second conveyor line B, the third conveyor line C and the fourth conveyor line D can also change the configuration mode and the conveying direction according to the process requirements.

[0060] After being combined into a composite board 80, the composite board 80 moves to the hot pressing processing area 50 along the conveying direction of the second conveyor line B, and the hot pressing processing area 50 is used to press the composite board 80 at a predetermined temperature, so that each board in the composite board 80 is tightly combined through hot pressing. Among them, the composite board 80 referred to in the embodiment of the present application can be but not limited to a purification board, which has the effects of dustproof, antistatic, antibacterial and not easy to be affected by moisture, and is widely used in clean rooms with strict requirements on indoor environment such as electronics, pharmaceuticals, food, biology and precision instrument manufacturing. The first board 71 can be but not limited to core materials such as glass magnesium board, gypsum board, aluminum honeycomb and paper honeycomb. The second board 72 and the fourth board 74 can be but not limited to metal plates, such as steel plates and aluminum plates, wherein the second board 72 is pressed to form a lower box body, and the fourth board 74 is used to cover the upper cover of the lower box body. In addition, the third board 73 is a rock wool core material, which is arranged in the lower box body with the first board 71 and can be closed by the upper cover.

[0061] The assembly processing area B1 includes a first station B11, a second station B12 and a third station B13 in sequence along the conveying direction of the second conveyor line B, and at least a portion of the third conveyor line C overlaps with the second conveyor line B in the projection direction of the second conveyor line B (e.g. Figure 4As shown), and connected to the second station B12 on the transport route, and the flipping station D1 corresponds to the third station B13. In the above-mentioned plate assembly process, the first processed plate is first transported to the first station B11 by the first conveyor line A, and after being combined with the second plate 72 to form the second processed plate, the second roller frame 61B drives the second processed plate to the second station B12, so that the third plate 73 can be combined with the second processed plate at the second station B12 to form the third processed plate. Finally, the second roller frame 61B drives the third processed plate to the third station B13, so that the fourth plate 74 can be combined with the third processed plate at the third station B13 to form a composite plate 80.

[0062] In addition, the configuration of the sheet area A1 to be assembled can also be planned into several different storage areas according to the use requirements to correspond to different processing procedures. For example, the sheet area A1 to be assembled includes a first storage area A11 and a second storage area A12, and the first storage area A11 corresponds to the first station B11, and the second storage area A12 corresponds to the third station B13. In this way, it is convenient to move the first processing board of the first storage area A11 to the first station B11 to combine with the second sheet 72. At the same time, the first processing board of the second storage area A12 can also be moved to the third station B13, and the first processing board is combined with the third sheet 73 of the third processing board at the third station B13, and the fourth sheet 74 is combined with the first processing board, so that the third sheet 73 is sandwiched between the two first sheets 71 to form a multi-layer composite board 80.

[0063] In some embodiments of the present application, the loading station 10 of the first conveyor line A includes a feeding area 11 and a working area 12. The feeding area 11 can be the ground or a accommodating structure on one side of the first conveyor line A, which is used to pick up and place the first plate 71. The working area 12 is provided with an automatic stacking device 13, and the first roller frame 61A includes a first conveying rail 611, a second conveying rail 612, two opposite guide brackets 62 and a first power source 63A (such as Figure 1 and Figure 5 ). The first transport track 611 and the second transport track 612 are disposed between the two guide brackets 62, and the first power source 63A is used to drive the transport track 61 to transport the first plate 71. In this embodiment, the first power source 63A is connected between the first transport track 611 and the second transport track 612, and can drive the first transport track 611 and the second transport track 612 to transport the first plate 71, and the transport speed of the first transport track 611 is greater than the transport speed of the second transport track 612. For example, the first power source 63A is a motor, the first transport track 611 and the second transport track 612 are conveyor belts, and a transmission mechanism (such as a speed reduction mechanism) is disposed between the motor and the conveyor belt, and can drive the two conveyor belts to produce different transport speeds respectively.

[0064] The automatic palletizing device 13 is disposed on one side of the first conveying track 611, and is used to pick up and place the first plate 71 between the feeding area 11 and the first conveying track 611. When the automatic palletizing device 13 places the first plate 71 on the first conveying track 611, there is a gap between the first plate 71 and the previous first plate 71 on the second conveying track 612, and the transmission speed of the first conveying track 611 is greater than the transmission speed of the second conveying track 612, so that when the first conveying track 611 transmits the first plate 71 to the second conveying track 612, the gap between the two first plates 71 is reduced, or the gap between the two first plates 71 is eliminated to achieve mutual proximity. Figure 6 As shown, through the above speed difference, after the first plates 71 are placed one by one on the first conveying track 611, they can quickly move toward the second conveying track 612 and abut against the previous first plate 71 to avoid a gap between the two plates and affect the accuracy of the cutting position.

[0065] In this embodiment, the automatic palletizing device 13 is an intelligent robot, and includes a palletizing robot 131 and a gripper 132 (such as Figures 10 to 13 As shown). The gripper 132 includes a coupling 1321, a fixed frame 1322 and a plurality of mounting brackets 1323. The coupling 1321 and the plurality of mounting brackets 1323 are respectively arranged on two opposite sides of the fixed frame 1322, and the palletizing robot 131 is connected to the coupling, so that the palletizing robot 131 drives the gripper 132 through the coupling 1321 to pick up and place the first plate 71 between the feeding area 11 of the loading station 10 and the first conveying track 611. In addition, the plurality of mounting brackets 1323 are arranged at intervals along the extension direction of the fixed frame 1322, and a plurality of suction cup assemblies 133 are arranged at intervals on each mounting bracket 1323, and can be moved with the gripper 132 to pick up and place the first plate 71.

[0066] In addition, the suction cup assembly 133 includes a buffer rod 1331, a vacuum generator 1332 and a suction cup 1333. The buffer rod 1331 is connected to the mounting bracket 1323, and the vacuum generator 1332 is connected between the buffer rod 1331 and the suction cup 1333, so as to generate vacuum suction in the suction cup 1333 when the suction cup 1333 is attached to the surface of the first plate 71, so as to firmly adsorb the first plate 71.

[0067] For example, the automatic palletizing device 13 can be a 4-axis robot, and the fixed frame 1322 is set at the end of the gripper 132, and can be displaced in 3D space with the gripper 132. Among them, the fixed frame 1322 is welded from steel, and has the advantages of strong rigidity and light weight, and the suction cup is a rubber vacuum suction cup with a diameter of 80mm, which can provide sufficient adsorption area to improve the adsorption effect. Therefore, during operation, the gripper 132 can move in 3D between the feeding area 11 and the first conveying track 611, and firmly adsorb the first plate 71 through the multiple suction cup assemblies 133 on the mounting bracket 1323, so as to transport the first plate 71 to the first conveying track 611 for transmission, processing and other related operations.

[0068] It is worth noting that, since the suction cup 1333 is provided with a buffer rod 1331, it can ensure elastic adjustment when the surface of the first plate 71 is uneven, and reduce external vibration or impact during the adsorption process, and each suction cup 1333 can control adsorption or release individually. For example, when there is a slight unevenness or error on the surface of the material adsorbed by the suction cup assembly 133, the buffer rod 1331 can make slight elastic adjustments while in contact to cope with changes in the material surface, ensuring that the adsorption effect is not affected by surface irregularities. Therefore, the configuration of the buffer rod 1331 helps the suction cup 1333 maintain a stable adsorption effect under various uncertain conditions and reliably handle materials of different shapes and surface states.

[0069] In some embodiments, the automatic palletizing device 13 further includes a control device 134, which is electrically connected to the palletizing robot 131 and the gripper 132, respectively. In this way, the control device 134 can control the movement of the palletizing robot 131, the opening and closing of the vacuum generator 1332, and the detection of the vacuum state in the suction cup 1333 by presetting or real-time operation, so as to achieve the movement, adsorption and release of the first plate 71, and when a vacuum state is not present in a certain suction cup 1333, the control device 134 turns off all vacuum generators 1332 on the same mounting bracket 1323 as the suction cup 1333. In other words, in the control of the suction cup assembly 133, it can also be set to regional synchronous adsorption, for example, the mounting bracket 1323 is a cross bar, and multiple suction cup assemblies 133 are arranged at intervals along the extension direction of the cross bar, and the suction cup assembly 133 on each cross bar can be synchronously actuated. When the surface error of the material is too large and some suction cup assemblies 133 cannot absorb the material, the suction cup assemblies 133 in the same row will automatically close without affecting the use of the suction cup assemblies 133 on other mounting brackets 1323. This regional synchronization design can effectively improve the efficiency of the system, ensuring that timely measures can be taken when problems occur in a specific area to interrupt unnecessary suction actions without adversely affecting the overall operation.

[0070] In such an industrial environment, in order to further improve safety and prevent unexpected risks in the operating area of ​​the automatic palletizing equipment 13, a safety fence is also set around the automatic palletizing equipment 13 to prevent workers from entering the working area of ​​the automatic palletizing equipment 13 to avoid accidents. For example, the safety fence is 1800mm high and is set on one side of the automatic palletizing equipment 13. It is designed with a yellow warning color so that workers can clearly identify it and avoid mistakenly entering the working area of ​​the automatic palletizing equipment 13. Of course, in addition to being set around the automatic palletizing equipment 13, the safety fence can also be set at the entrance of other production lines, or in areas where workers are easily injured, to separate non-working areas, which can effectively reduce the occurrence of industrial accidents.

[0071] Alternatively, the automatic palletizing equipment 13 may also be provided with a safe operation mode, for example, with functions such as emergency stop, fault alarm, start, and pause. In some embodiments, the safety fence is also provided with a grating, and is linked with the palletizing robot 131. Once the grating system detects that someone has entered the range of the safety fence, a stop signal will be sent to the palletizing robot 131 to quickly interrupt its action. At the same time, the palletizing robot 131 will trigger a warning signal to the control device 134, or a warning device may be provided around the automatic palletizing equipment 13, which directly receives the warning signal of the palletizing robot 131 and triggers sound and light warnings, reminding on-site personnel to stay away from dangerous areas, so that personnel and the automatic palletizing equipment 13 can work together more safely in the same working environment.

[0072] In order to effectively improve the conveying efficiency of the first plate 71, in some embodiments, the top surface of the first conveying track 611 is higher than the top surface of the second conveying track 612, forming a conveying method from high to low. For example, the side of the first conveying track 611 away from the second conveying track 612 is higher than the side close to the second conveying track 612, so that the first conveying track 611 is inclined from top to bottom toward the second conveying track 612 (for example, Figure 3 As shown, without affecting the horizontal conveying angle of the plate, it is in an inclined state with the left side higher and the right side lower), so that the first plate 71 can be assisted by gravity during the conveying process, which helps to improve the conveying efficiency.

[0073] In order to improve the stability of the first plate 71 during the conveying process, in some embodiments of the present application, a fixed bracket 641 is provided above the second conveying track 612, and a scale 65 (such as Figure 6 and Figure 7As shown). In this embodiment, the fixed bracket 641 spans over the two guide brackets 62 and is suspended above the second transport track 612. The ruler 65 is disposed between the fixed bracket 641 and the second transport track 612, and has a predetermined height with the second transport track 612, and the predetermined height matches the thickness of the first plate 71, so that the first plate 71 can be restricted to be transported between the ruler 65 and the second transport track 612. Among them, a plurality of rollers are disposed on the side of the ruler 65 facing the second transport track 612, and the plurality of rollers can roll on the top surface of the first plate 71 during the transport process of the first plate 71, so that the first plate 71 is clamped between the rollers and the second transport track 612, thereby limiting the first plate 71 within the above-mentioned predetermined height to achieve stable transport.

[0074] Similarly, in order to further improve the stability of the first plate 71 during the conveying process, in some embodiments, a roller 66 (such as Figure 7 As shown). The roller 66 may be, but is not limited to, a cylinder, and the outer circumferential surface of the roller 66 abuts against the surface of the second transport track 612 and the end of the ruler 65 facing the first transport track 611. It is worth mentioning that in the present embodiment, the roller 66 is not provided with a fixed structure, but is directly placed on the second transport track 612, and its movement is restricted by the end of the ruler 65. Therefore, when the first power source 63A drives the second transport track 612 to operate, the second transport track 612 drives the roller 66 to abut against the end of the ruler 65 and generates self-rotation, so that when the first plate 71 is transferred to the second transport track 612, the roller 66 presses against the first plate 71 by its own weight, and can guide the first plate 71 to be transferred between the ruler 65 and the second transport track 612, thereby ensuring the stability of the transfer process.

[0075] Regarding the glue spraying processing area 20, it has a glue spraying device 21 arranged between two guide brackets 62, and the first roller frame 61A is provided with a second power source 63B in the glue spraying processing area 20, and a third conveying track 613, a fourth conveying track 614 and a fifth conveying track 615 are arranged in sequence along the conveying direction of the second conveying line B, so that the fourth conveying track 614 is between the third conveying track 613 and the fifth conveying track 615 (such as Figures 14 to 19). The glue spraying equipment 21 includes a spray room 211 and a glue spraying tool 212. The spray room 211 spans over the fourth conveying track 614 and is provided with an entrance toward the third conveying track 613 and an exit toward the fifth conveying track 615. The glue spraying tool 212 is movably arranged in the spray room 211 to spray the adhesive onto the surface of the first plate 71. The second power source 63B is used to drive the third conveying track 613, the fourth conveying track 614 and the fifth conveying track 615 to convey the first plate 71, and the conveying speed of the fourth conveying track 614 is lower than the conveying speed of the third conveying track 613 and the fifth conveying track 615.

[0076] In this way, by the difference in the conveying speed of each conveying track, the first plate 71 can be controlled to have a spacing with the previous first plate 71 on the fourth conveying track 614 before and after the entrance of the spray room 211, and the spacing can be eliminated after entering the entrance. It can be understood that, through the above speed difference, the two first plates 71 are separated from each other before entering the glue spraying processing area 20. After entering the entrance of the spray room 211, the two first plates 71 abut against each other and come close to each other, so that the two first plates 71 can achieve continuous spraying in the spray room 211, and realize uninterrupted and uniform spraying to improve the adhesion effect. At the same time, after moving out of the spray room 211, the speed difference between the fourth conveying track 614 and the fifth conveying track 615 separates the two first plates 71 again. Therefore, through the above design, the front and rear first plates are transported separately before spraying, come close to each other during spraying, and are separated again after spraying.

[0077] In addition, in order to prevent the first plate 71 from shifting during the spraying process, which would result in uneven spraying, a baffle 6141 may be provided on the side of the fourth transport track 614 corresponding to one of the guide brackets 63, and the baffle extends along the conveying direction of the fourth transport track 614, thereby preventing the first plate 71 from shifting and assisting in guiding the first plate 71 to move along the conveying direction of the fourth transport track 614.

[0078] In terms of speed difference control, it can be achieved by adjusting the friction of each transport track, or by setting a transmission mechanism with different reduction ratios between the second power source 63B and each transport track. For example, the fourth transport track 614 is a conveyor roller set, the third transport track 613 and the fifth transport track 615 are conveyor belts, and the friction between the conveyor roller set and the first plate 71 is less than the friction between the third transport track 613 and the fifth transport track 615 and the first plate 71. Therefore, when the second power source 63B drives each transport track to operate, the third transport track 613 and the fifth transport track 615 with larger friction can drive the first plate 71 to be transported quickly, while when the first plate 71 is located on the fourth transport track 614 with smaller friction, the transport speed is relatively slow.

[0079] In terms of the spraying structure, a moving track 2111 is also provided in the spray room 211, and the glue spraying tool 212 includes a transmission arm 2121 and a glue spraying bracket 2122. The transmission arm 2121 is provided on the moving track 2111, and can move back and forth in the spray room 211 along the moving track 2111 (that is, move laterally between the two guide brackets 62). The glue spraying bracket 2122 is connected to the bottom of the transmission arm 2121, and is provided with a plurality of pouring heads 2123, and the plurality of pouring heads 2123 are arranged along the long side direction of the glue spraying bracket 2122, for example, the plurality of pouring heads 2123 are arranged at equal intervals. In addition, the long side direction of the glue spraying bracket 2122 and the conveying direction of the fourth conveying track 614 have an angle θ of not more than 90 degrees, so that the glue spraying bracket 2122 and each pouring head 2123 are arranged in an inclined manner.

[0080] Therefore, when each pouring head 2123 moves back and forth with the transmission arm 2121 to spray the adhesive, the adhesive can form an effect similar to a diamond on the plate to increase the bonding force. For example, if the arrangement direction of the multiple pouring heads 2123 is parallel to the transmission direction of the fourth conveying track 614, only a plurality of inclined and mutually parallel adhesive strips will be formed on the moving first plate 71, resulting in gaps between the multiple adhesive strips and no connection, and the bonding effect is relatively poor. When the multiple pouring heads 2123 are arranged obliquely for reciprocating spraying, a plurality of connected and diamond-shaped adhesive strips 91 (such as Fig.16 As shown), thereby reducing voids and increasing bonding effectiveness.

[0081] In order to achieve a continuous supply of adhesive, in terms of structural configuration, a material tank structure 2124 for storing adhesive raw materials is provided on the transmission arm 2121, a mixing space connecting the material tank structure 2124 and the pouring head 2123 is provided in the glue spraying bracket 2122, and a control valve 2125 is provided between the mixing space and the material tank structure 2124 and the pouring head 2123. The control valve 2125 is used to control the adhesive raw materials in the material tank structure 2124 to enter the mixing space of the glue spraying bracket 2122, and to control the supply of the mixed adhesive in the mixing space to the multiple pouring heads 2123, so as to achieve the spraying of the adhesive.

[0082] For example, a plurality of material tanks 21241 are provided in the material tank structure 2124 to store various adhesives, and a connecting pipe 21242 is provided between the material tank 21241 and the mixing space of the glue spraying bracket 2122 to transfer the adhesive raw material to the mixing space. Among them, a regulating valve 21243 is also provided on the connecting pipe 21242 to allow the adhesive raw material to flow back to the material tank 21241. For example, a plurality of material tanks 21241 can store adhesive raw materials such as white material and black material respectively, and after being transferred to the mixing space, the adhesive is formed by stirring with a constant speed mixer, and the adhesive formed by mixing the two adhesive raw materials can have a viscosity range set between 2000-12000CPS.

[0083] In terms of control, the glue spraying equipment 21 also includes a first control device 213, which is electrically connected to the transmission arm 2121 and the glue spraying bracket 2122, and can control the speed at which the transmission arm 2121 drives the glue spraying bracket 2122 to move back and forth, as well as control the feed amount of the adhesive raw materials in each material tank 21241 into the mixing space and the amount of glue applied by the mixed adhesive flowing out of each pouring head 2123. In this way, the first control device 213 can flexibly adjust the density of the adhesive spraying by controlling the reciprocating speed of the glue spraying bracket 2122. And by controlling the mixing ratio and glue application amount of the adhesive raw materials, the bonding effect of the adhesive can be further adjusted to meet the needs of different processes and applications.

[0084] Of course, in order to prevent the residual adhesive from affecting the next mixing ratio, in some embodiments, a cleaning device is also provided on the transmission arm 2121. The cleaning device is electrically connected to the first control device 213 and is used to supply cleaning liquid or cleaning gas to the mixing space. For example, the cleaning device is equipped with a cleaning agent tank, which can store cleaning liquid or cleaning gas, and clean the mixing space under the control of the first control device 213.

[0085] In addition, the first control device 213 can also close the control valve 2125 and start the cleaning device to perform the cleaning procedure after a predetermined time has passed when the glue spraying tool 212 is in a shutdown state by setting the time. For example, if the time is set to 10 minutes, the first control device 213 can control the cleaning device to perform the cleaning procedure on the mixing space 10 minutes after the glue spraying tool 212 is stopped, and close the control valve 2125 at the same time, so as to ensure that no interference action will occur during the cleaning process, thereby affecting the cleaning effect or safety.

[0086] It is worth noting that, in addition to being arranged on the first conveyor line A, the glue spraying equipment 21 can also be arranged on the second roller frame 61B of the second conveyor line B and the fourth roller frame 61D of the fourth conveyor line D. The glue spraying equipment 21 is respectively located in front of the assembly processing area B1 in the conveying direction of the second roller frame 61B (for example, in front of the first station B11), and in front of the flipping station D1 in the conveying direction of the fourth roller frame 61D. In this way, the glue spraying equipment 21 of the second roller frame 61B can spray the adhesive on the second plate 72 (lower box), so that the second plate 72 can be combined with the side of the first processing plate that is not sprayed with the adhesive, and the glue spraying equipment 21 on the fourth roller frame 61D can spray the adhesive on the fourth plate 74 (upper cover), so that the fourth plate 74 can be combined with the side of the first plate 71 that is not sprayed with the adhesive or the third plate 73 (depending on the stacking of the plates).

[0087] Therefore, in the embodiment of the present application, the glue spraying processing area 20 can evenly distribute the adhesive on the plate by tilting and arranging multiple pouring heads 2123 to spray back and forth, forming a diamond-like and interconnected effect to increase the bonding force. At the same time, the first control device 213 can also control the speed of the reciprocating spraying, the mixing ratio of the adhesive and the amount of glue applied, and flexibly adjust the density and bonding effect of the adhesive spraying, so as to meet the needs of various processes.

[0088] In some embodiments of the present application, a cutting processing area A2 and a dust removal station 40 are further provided between the loading station 10 and the glue spraying processing area 20 of the first conveyor line A. The cutting processing area A2 is located between the loading station 10 and the dust removal station 40, and is provided with a cutting machine for cutting the first plate 71 with a shearing tool after the first plate 71 passes a predetermined distance through the cutting processing area A2, so that the first plate 71 meets the preset specifications. It is worth mentioning that the cutting surface of the shearing tool is a cone angle or its cutting edge is inclined, so that the cross section of the first plate 71 after cutting forms an inclined surface 77 (such as Fig. 20 As shown in FIG. 1 , the first plate 71 is not easily broken during the cutting process, thereby effectively improving the process yield.

[0089] After the first plate 71 is cut, debris such as iron filings or powder after cutting is likely to remain on the surface (for example, iron filings will be generated after continuous wire cutting of sandwich panels, and powder will be generated after cutting of glass magnesium panels), and it is difficult to clean it thoroughly manually, thus affecting the spraying effect of the adhesive. Therefore, the first plate 71 after cutting is cleaned by the dust removal station 40 to ensure the smooth progress of subsequent processing operations, especially for the spraying of the adhesive, providing a more efficient cleaning solution. The dust removal station 40 is provided with a cleaning device 41, and the cleaning device 41 includes an equipment frame 411, a roller brush 412 and a third power source 413 (such as Figure 21 to Figure 23As shown). The two opposite sides of the equipment frame 411 are respectively arranged on the two guide brackets 62 of the first roller frame 61A, and the roller brush 412 spans above the first roller frame 61A and has a rotating shaft 4121 and a plurality of bristles 4122. Among them, the third power source 413 can be but not limited to a rotating motor, connected to the rotating shaft 4121 of the roller brush 412, and when the first plate 71 passes through the roller brush 412, the rotating shaft 4121 can be driven to drive the roller brush 412 to rotate, so that the roller brush 412 rolls on the surface of the first plate 71, and the bristles 4122 completely remove the debris on the surface of the first plate 71, thereby achieving a cleaning effect.

[0090] In this embodiment, the multiple bristles 4122 of the roller brush 412 are arranged along the axial direction of the rotating shaft 4121 and are arranged around the outer peripheral surface of the rotating shaft 4121, so that the bristles 4122 are evenly distributed on the entire roller brush 412, thereby enhancing the cleaning coverage area. In the axial direction of the rotating shaft 4121, the bristles 4122 located on the two opposite sides of the rotating shaft 4121 are respectively inclined from the middle position of the rotating shaft 4121 toward the two opposite ends of the rotating shaft 4121. In this way, through the inclined arrangement of the bristles 4122 on the two sides in different directions, when the third power source 413 drives the roller brush 412 to rotate, the bristles 4122 can contact the surface of the first plate 71 in different directions and angles, ensuring a full-range and uniform cleaning effect during the rolling process.

[0091] In some embodiments of the present application, the cleaning device 41 includes an inlet and an outlet corresponding to the roller brush 412, and the inlet faces the cutting processing area A2, and the outlet faces the glue spraying processing area 20. In the projection direction of the inlet of the cleaning device 41, the multiple bristles 4122 of the roller brush 412 are tilted from the side of the rotating shaft 4121 away from the first roller frame 61A to the side close to the first roller frame 61A. Therefore, when the roller brush 412 rolls on the surface of the first plate 71, the bristles 4122 on both sides can be tilted and rotated from the center of the first plate 71 to the direction of the two guide brackets 62, so that the debris on the first plate 71 can be pushed to the outside and removed during the cleaning process.

[0092] In addition, in order to prevent the roller brush 412 from being too close to the first plate 71 during the cleaning process, resulting in excessive pressure, causing damage to the first plate 71, or being too far away and reducing the cleaning effect, in some embodiments, a transmission bracket 4111 and a lifting device 4112 are provided on the equipment frame 411. The roller brush 412 and the third power source 413 are respectively provided on the transmission bracket 4111, and the lifting device 4112 is connected to the transmission bracket 4111 to drive the transmission bracket 4111 to move closer to or away from the first roller frame 61A, and the distance between the plurality of bristles 4122 and the first roller frame 61A can be adjusted. For example, the equipment frame 411 is a gantry sweeper, which is directly installed on both sides of the first roller frame 61A by bolts, and the transmission bracket 4111 is movably provided on the gantry sweeper and can be moved up and down. Therefore, by raising and lowering the roller brush 412, the optimal cleaning distance from the first plate 71 can be maintained, ensuring that the best effect can be maintained when processing plates of different thicknesses, while reducing the risk of damage, making the processing process more flexible.

[0093] In some embodiments of the present application, the lifting device 4112 includes a shaft 41121, a transmission mechanism 41122, and a fourth power source 41123. One end of the shaft 41121 is fixed to the transmission bracket 4111, and the other end is connected to the transmission mechanism 41122, and the transmission mechanism 41122 and the fourth power source 41123 are arranged on the equipment frame 411. The fourth power source 41123 is connected to the transmission mechanism 41122, and can drive the transmission mechanism 41122 to move up and down along its own central axis. For example, the fourth power source 41123 and the transmission mechanism 41122 can be pneumatic cylinders, and the shaft 41121 is driven to rise and fall through the linear extension and retraction of the transmission mechanism 41122. Alternatively, the fourth power source 41123 is a rotating motor, and the transmission mechanism 41122 is a combination of a screw and a slider. The motor drives the screw to rotate, so that the slider is converted into up and down movement, and drives the shaft 41121 to rise and fall.

[0094] In order to achieve automatic cleaning and automatic lifting of the roller brush 412, in some embodiments, the dust removal station 40 also includes a second control device 401. The second control device 401 is arranged on the equipment frame 411, and is electrically connected to the third power source 413 and the fourth power source 41123, respectively, to start and shut down the third power source 413 and the fourth power source 41123, so as to achieve automatic cleaning and automatic lifting to adapt to plates of different thicknesses. Of course, in terms of lifting control, the user can set the lifting height of the roller brush 412 according to actual needs, or set a sensor on the dust removal station 40 to automatically detect the thickness of the plate and feed back to the second control device 401, so that the second control device 401 automatically adjusts the lifting height according to the detected plate thickness.

[0095] In addition, in order to accelerate the first plate 71 after cleaning to leave the roller brush 412 and prevent the debris of other first plates 71 from splashing onto the first plate 71 again during the cleaning process, in other embodiments of the present application, the first roller frame 61A is sequentially provided with a feed roller group 601 and a discharge roller group 602 along the conveying direction. Among them, the discharge end of the feed roller group 601 and the feed end of the discharge roller group 602 overlap with the working area of ​​the roller brush 412 in the projection direction of the cleaning device 41, and in the horizontal direction of the first roller frame 61A, the feed end of the discharge roller group 602 is higher than the discharge end of the feed roller group 601, and the rotation speed of the discharge roller group 602 is greater than the rotation speed of the feed roller group 601. In this way, the first plate 71 can enter the cleaning range of the roller brush 412 at a slower speed through the feed roller set 601, so as to more thoroughly deal with the dirt, and after being cleaned by the roller brush 412, the first plate 71 can be quickly taken away from the range of the roller brush 412 by the discharge roller set 602, and separated from the first plate 71 being cleaned, so as to reduce the chance of dirt attaching again. At the same time, by configuring the feed end of the discharge roller set 602 to be higher than the discharge end of the feed roller set 601, the cleaned first plate 71 can be further made slightly higher than the uncleaned first plate 71, thereby reducing the chance of secondary contamination.

[0096] It is worth noting that in the past, the cut plates were usually cleaned manually, which not only made it difficult to completely remove the iron filings or dust, but also caused quality risks, affecting the quality of subsequent processing of the plates. Therefore, in the embodiment of the present application, the surface of the plate is cleaned by a roller brush 412, which can completely remove the iron filings after the continuous wire cutting of the plate (such as a sandwich panel), and quickly remove the powder generated after the cutting of the plate (such as a glass magnesium board), which can effectively solve the problem of manual cleaning.

[0097] In some embodiments of the present application, the third conveyor line C is provided with a cutting processing area 30 as a cutting channel for the rock wool core material, for cutting the third plate 73 (eg, rock wool core material). Figure 1 , Figure 24 to Figure 29As shown, the cutting processing area 30 includes a cutting device 31, and the cutting device 31 has a fixed frame 311, a follower frame 312 and a cutting assembly 313. The fixed frame 311 is arranged on the third roller frame 61C, and the follower frame 312 is arranged on the side of the fixed frame 311 facing the third roller frame 61C, and can be displaced back and forth along the extension direction of the third roller frame 61C. The cutting assembly 313 is movably arranged on the follower frame 312, and includes a cutting machine 3131 and a pressing plate 3132. The follower frame 312 can drive the cutting assembly 313 to reciprocate in the conveying direction of the third roller frame 61C, and a track 3120 is arranged on the follower frame 312, and the cutting machine 3131 is movably arranged on the track 3120, and can be displaced along the cutting stroke. The cutting stroke of the cutting machine 3131 intersects with the conveying direction of the third roller frame 61C. For example, the third roller frame 61C conveys the plate along the first axial direction Y, so that the follower frame 312 can drive the cutting assembly 313 to reciprocate along the first axial direction Y of the conveying plate on the third roller frame 61C. The cutting machine 3131 has a cutting stroke that is displaced along the second axial direction X on the third roller frame 61C, and the first axial direction Y forms a 90-degree angle with the second axial direction X, ensuring that the third plate 73 conveyed by the third roller frame 61C can accurately maintain a rectangular shape after cutting, and at the same time, effectively compensate for the third plate 73 that may be deformed in appearance, so as to achieve high accuracy and stability in the cutting process.

[0098] In addition, the pressing plate 3132 of the cutting assembly 313 has a lifting stroke that can rise or fall relative to the third roller frame 61C, and can be lowered and pressed against the third plate 73 during the process of the cutting machine 3131 cutting the third plate 73 to avoid slipping during the cutting process, thereby achieving a stable cutting effect, and after the cutting stroke is completed, it can rise and separate from the third plate 73.

[0099] In some embodiments, the cutting machine 3131 includes a housing 31311 and a rotating cutter 31312. The housing 31311 has an opening 31313 at the bottom, and the rotating cutter 31312 is disposed in the housing 31311 and partially exposed outside the opening 31313. The housing 31311 is provided with cleaning tools 31314 on two opposite sides of the opening 31313, and the cleaning tools 31314 correspond to the cutting edges of the rotating cutter 31312 respectively, so as to clean the surface of the third plate 73 when the rotating cutter 31312 cuts the third plate 73. For example, the rotating cutter 31312 may be a circular saw, and a portion of the rotating cutter 31312 is exposed outside the opening 31313, so as to achieve the cutting of the third plate 73. The cleaning tool 31314 may be, but is not limited to, a brush, which may contact the third plate 73 with the displacement of the cutting stroke during the cutting process of the rotating cutter 31312, thereby achieving a cleaning effect.

[0100] In the process of cutting the plate, in order to prevent dust from floating in the working environment and causing harm to the human body, in some embodiments, the cutting processing area 30 also includes a dust collecting device 33, and the housing 31311 of the cutting machine 3131 can be provided with a docking port 31315 in the structure. The dust collecting device 33 is connected to the docking port 31315 of the housing 31311, and is used to clean the surface of the third plate 73 synchronously with the cleaning tools 31314 on both sides of the opening 31313. It can be understood that through the rotation cleaning of the cleaning tool 31314 and the dust collecting function of the dust collecting device 33, the dust and debris generated during the cutting process can be effectively collected, thereby protecting the health of the staff and maintaining the air quality of the surrounding environment. In practice, the housing 31311 of the cutting machine 3131 can also be provided with a saw blade guard to prevent dust and debris from splashing during the cutting process, and at the same time improve the collection efficiency of the dust collecting device 33, which can not only protect the safety of the staff, but also help to keep the working environment clean and improve the convenience of operation.

[0101] In order to further improve the effect of stable cutting, in some embodiments, the cutting assembly 313 is further provided with a limiter 3133. The extension direction of the pressing plate 3132 of the cutting assembly 313 is in the same direction as the cutting stroke of the cutting machine 3131, so as to improve the support and stability, and the two opposite ends of the pressing plate 3132 correspond to the two opposite sides of the third roller frame 61C, and at least one end of the pressing plate 3132 is provided with a limiter 3133. In this embodiment, the limiter 3133 extends along the conveying direction of the third roller frame 61C, and when the pressing plate 3132 presses against the third plate 73, the third plate 73 is stopped from deflecting in the direction of the cutting stroke, so as to ensure that the first plate 71 is kept stable during the cutting process, and to avoid unnecessary deflection affecting the cutting effect. For example, a limiting member 3133 is disposed at one end of the pressing plate 3132 in the second axial direction X, and the limiting member 3133 extends along the first axial direction Y to stop the third plate 73 from deviating in the second axial direction X when the pressing plate 3132 presses against the third plate 73 .

[0102] In some embodiments of the present application, the cutting device 31 further includes a third control device 314, and the third control device 314 is electrically connected to the follower frame 312 and the cutting assembly 313. During the cutting process, the third control device 314 is used to control the pressing plate 3132 to descend and press against the third plate 73, and drive the follower frame 312 to move with the third plate 73 within a predetermined time, so that the follower frame 312 and the third plate 73 can move synchronously (the cutting assembly 313 moves synchronously with the follower frame 312). At the same time, the third control device 314 synchronously controls the cutting machine 3131 to complete the cutting stroke within a predetermined time, so that the cutting machine 3131 can cut the third plate 73 while moving synchronously with the third plate 73, so as to ensure the accuracy of the cutting process.

[0103] In addition, after the predetermined time period has expired, the third control device 314 controls the pressing plate 3132 to rise to separate from the third plate 73 , and drives the follower frame 312 to return to the starting position, waiting for the next cutting operation of the third plate 73 .

[0104] In order to ensure that the downward pressure of the pressing plate 3132 does not cause damage to the third plate when fixing the third plate, in some embodiments, the cutting device 31 also includes a pressure regulating device 315. The pressure regulating device 315 can be, but is not limited to, a gas pressure regulating device, which is connected between the follower frame 312 and the pressing plate 3132, and is electrically connected to the third control device 314. In this way, the third control device 314 can control the lifting stroke of the pressing plate 3132 and the downward pressure applied by the pressing plate 3132 to the rock wool by adjusting the pressure regulating device 315, so as to adapt to different rock wool bulk density pressure adjustment requirements, so that the pressing plate 3132 can be firmly pressed against the third plate 73, while avoiding any damage to the third plate 73.

[0105] In some other embodiments of the present application, a floating counting roller 32 is further provided between two opposite sides of the third roller frame 61C. The floating counting roller 32 includes two lifting mechanisms 321, a roller 322 connected between the two lifting mechanisms 321, and a counting wheel 323 sleeved on the roller 322. The lifting mechanism 321 may be, but is not limited to, a pneumatic floating mechanism. The two lifting mechanisms 321 are respectively provided on two opposite sides of the third roller frame 61C and are electrically connected to the third control device 314. The two lifting mechanisms 321 can be driven by the control of the third control device 314 to drive the roller 322 to rise or fall relative to the third roller frame 61C. At the same time, when the roller 322 descends, it drives the counting wheel 323 to roll on the third plate 73 to count the plate.

[0106] In addition, in some embodiments, the third conveyor line C also includes an eighth conveyor track 618 and a ninth conveyor track 619. The eighth conveyor track 618 extends along the second axial direction X and is connected to one end of the ninth conveyor track 619, and the ninth conveyor track 619 is inclined from the third conveyor line C to the second conveyor line B. In the projection direction of the second conveyor line B, the eighth conveyor track 618 intersects with the ninth conveyor track 619, and the ninth conveyor track 619 overlaps with the second conveyor line B. For example, the cutting processing area 30 is arranged on the eighth conveyor track 618, and the eighth conveyor track 618 spans above the first production line A and the second production line B along the first axial direction X, and the cut rock wool is transferred to the ninth conveyor track 619 via the eighth conveyor track 618 through the cutting processing area 30, and then the rock wool is transferred from top to bottom to the second conveyor line B via the ninth conveyor track 619.

[0107] In this way, the space required for the production line is effectively saved by configuring the third conveyor line C and the second conveyor line B up and down. Of course, the third conveyor line C is not limited to the intersecting conveyor tracks in terms of structural configuration and position, nor is it limited to being set above the second conveyor line B, and can be arbitrarily changed depending on actual needs. For example, in some possible embodiments, the third conveyor line C can also be only provided with the ninth conveyor track 619, and the cutting processing area 30 is set on the ninth conveyor track 619, or the third conveyor line C is set on the other side of the second conveyor line B relative to the first conveyor line A, and is parallel to the second conveyor line B.

[0108] As can be seen from the above description, when the cutting processing area 30 of the embodiment of the present application cuts the third plate 73, the cutting machine 3131 can cut the third plate 73 while moving synchronously with the third plate 73 to ensure the accuracy of the cutting process. At the same time, through the rotation cleaning of the cleaning tool 31314 and the dust collection function of the dust collection device 33, the dust and debris generated during the cutting process are effectively collected, thereby protecting the health of the workers and maintaining the air quality of the surrounding environment.

[0109] In the processing flow of the second conveyor line B, the hot pressing processing area 50 is a key step for firmly combining the panels, which can ensure that the composite panel 80 can meet the preset quality standards and performance requirements. Figure 1 , Fig.30 and Fig.31 As shown, the hot pressing processing area 50 has a hot pressing machine 51, and the second roller frame 61B is provided with a sixth conveying track 616 and a seventh conveying track 617 in the hot pressing processing area 50, and the hot pressing machine 51 is arranged between the sixth conveying track 616 and the seventh conveying track 617. The hot pressing machine 51 includes a heating cavity 511 and two pressurizing tracks 512 stacked on the heating cavity 511, and a predetermined temperature can be generated in the heating cavity 511, and a hot pressing channel is formed between the two pressurizing tracks 512. In addition, the height of the hot pressing channel matches the thickness of the composite board 80, and a plate inlet 501 is formed on the side facing the sixth conveying track 616, and a plate outlet 502 is formed on the side of the seventh conveying track 617, so that the composite board 80 can enter the hot pressing channel from the plate inlet 501 for hot pressing during the hot pressing process, and then be transported out from the plate outlet 502.

[0110] In this embodiment, the pressurizing crawler 512 has a plurality of heat-conducting pressing plates 5121 arranged at intervals. When the composite plate 80 enters the hot pressing channel from the plate inlet 501, the composite plate 80 is heated by the heating chamber 511 and pressed on the two opposite sides of the composite plate 80 by the two pressurizing crawlers 512, so that the composite plate 80 achieves the effect of hot pressing. In addition, during the hot pressing process, the two pressurizing crawlers 512 rotate relative to the composite plate 80, so that the plurality of heat-conducting pressing plates 5121 are pressed on the two opposite sides of the composite plate 80 in sequence, and drive the composite plate 80 to be transported toward the seventh transport track 617. It is worth noting that during the hot pressing process, this relative rotation action not only ensures that the heat-conducting pressing plates 5121 can be evenly pressed on the surface of the composite plate 80, but also drives the composite plate 80 to move along the transport direction of the seventh transport track 617, ensuring that the composite plate 80 can be stably transported to the predetermined position after the hot pressing effect, effectively improving the overall production efficiency.

[0111] Structurally, the hot press machine 51 may also include two side pressure tracks 513 to assist in driving the composite plate 80 to move in the transport direction of the seventh transport track 617. The side pressure tracks 513 are respectively arranged on two opposite sides of the heating chamber 511 and correspond to the heating channel, so that the two pressurizing tracks 512 and the two side pressure tracks 513 surround the outside of the heating channel. When the composite plate 80 enters the hot press channel, the two side pressure tracks 513 are respectively pushed against the two opposite sides of the composite plate 80 and rotate relative to the composite plate 80, and can synchronously drive the composite plate 80 to move with the pressurizing tracks 512.

[0112] In addition, in order to increase the pressing effect and assist in driving the composite plate 80 to move, in some embodiments, the side pressure track 513 includes a plurality of pressure blocks 5131 arranged at intervals. The pressing method of the plurality of pressure blocks 5131 is similar to that of the pressure track 512. After the composite plate 80 enters the plate inlet 501, the plurality of pressure blocks 5131 are pushed against the side of the composite plate 80 in sequence as the side pressure track 513 rotates, achieving the pressing and driving effect on the side of the composite plate 80, and the composite plate 80 is separated from the side of the composite plate 80 in sequence after the composite plate 80 passes through the plate outlet 502. In this way, through the upper and lower pressing of the plurality of hot pressing plates 5121 and the left and right pressing of the plurality of pressure blocks 5131, it can be ensured that each area of ​​the plate is pressed evenly, thereby improving the bonding effect between the plurality of plates.

[0113] In order to maintain the balance of the composite plate 80 during the pressing process, in some embodiments, the two pressurizing tracks 512 and the two side pressure tracks 513 are evenly arranged so that when the pressurizing block 5131 is pushed against the side of the composite plate 80, it is located between the heat-conducting pressure plates 5121 of the two pressurizing tracks 512, which can not only stably and evenly press the composite plate 80, but also smoothly drive the composite plate 80 to move.

[0114] In terms of heating the hot pressing processing area 50, the hot pressing machine 51 further includes a heating device, which is arranged on the heating cavity 511. The heating device is used to provide a heat source in the heating cavity 511 and heat the heat-conducting pressing plate 5121 to a predetermined temperature, thereby achieving a hot pressing effect on the composite board 80. For example, the air is heated by an electric heating wire to generate high-temperature air, so that the heat source is introduced into the heating cavity 511 in the form of high-temperature air, and the heat-conducting pressing plate 5121 can be uniformly heated to a predetermined temperature.

[0115] Of course, in addition to heating with high-temperature air, the heating device also uses other forms of heating technology to provide a controllable and stable heat source so that the heat-conducting pressing plate 5121 can achieve the required hot pressing conditions. For example, the heating device can also be an electric heating device, and combined with liquid heating technology, the heat source can heat the heat-conducting pressing plate 5121 in the form of electrically heated thermal oil.

[0116] In addition, since different application scenarios have different structural requirements for the composite board 80, the manufacturing specifications of the composite board 80 are not limited to a single thickness. Therefore, in order to enable the hot press machine 51 to achieve the best hot pressing effect on composite boards 80 of various specifications, in some embodiments, the hot press machine 51 also includes a lifting mechanism 514. Among them, the lifting mechanism 514 is connected to at least one of the two pressurizing crawlers 512 to adjust the height of the hot pressing channel. For example, the lifting mechanism 514 is connected to the upper pressurizing crawler 512, and can drive the upper pressurizing crawler 512 to rise and fall away from or approach the lower pressurizing crawler 512, thereby controlling the height of the hot pressing channel between the two pressurizing crawlers 512. It can be understood that through the configuration of the lifting mechanism 514, the hot press machine 51 can more flexibly adjust the height of the hot pressing channel, and can be applied to plates of different specifications.

[0117] In some embodiments of the present application, one side of the two pressurized crawlers 512 forming the plate inlet 501 is exposed outside the heating chamber 511, and one of the two pressurized crawlers 512 corresponds to the top of the sixth conveying track 616, and a fixed frame 5122 and a limiting roller 5123 are provided on this pressurized crawler 512. Among them, the limiting roller 5123 is connected to the fixed frame 5122 and suspended above the sixth conveying track 616 to guide the composite plate 80 into the hot pressing channel. It can be understood that the limiting roller 5123 helps to maintain the stability of the composite plate 80, reduce the shaking during the heating process, and thus improve the production accuracy of the product. At the same time, the suspension configuration of the limiting roller can also ensure the precise guidance of the composite plate 80, further improving the accuracy and consistency of the process.

[0118] Similarly, since the composite plate 80 is not limited to a single thickness, in order to enable the limiting roller 5123 to guide composite plates 80 of various specifications, a height adjustment mechanism 5124 is connected between the fixed frame 5122 and the limiting roller 5123. The height adjustment mechanism 5124 can be, but is not limited to, a telescopic mechanism, which is used to drive the limiting roller 5123 to move on the fixed frame 5122, and can adjust the predetermined distance between the limiting roller 5123 and the sixth conveying track 616, so that the predetermined distance corresponds to the height of the composite plate 80, thereby ensuring accurate guidance of the composite plate 80 and maintaining the stability of the composite plate 80 during the processing.

[0119] In the embodiment of the present application, through the cooperation of the heating device, the pressure track 512, the side pressure track 513 and the limiting roller 5123, hot pressing and stable guidance of the plate can be achieved, making the process more precise, stable and efficient.

[0120] From the above description, it can be seen that in the embodiment of the present application, the heating device, the hot pressing track, the side pressing track and the limiting roller cooperate so that after the plate enters the hot pressing channel, it is continuously pressed by the multiple hot pressing plates of the two hot pressing tracks on the two opposite sides of the plate, so that the multi-layer plates in the plate are closely attached to each other. At the same time, the contact heat conduction of the hot pressing plate solidifies the adhesive between the multi-layer plates, thereby improving the adhesion strength and uniformity between the multi-layer plates, and maintaining the thickness of the plates in different areas within the precision error range, thereby significantly improving the yield of the product.

[0121] The following is a further description of the processing flow in the embodiments of the present application.

[0122] In the processing flow of the first conveyor line A, the multiple first plates 71 are first placed one by one on the first roller frame 61A by the automatic stacking equipment 13, and then sequentially pass through the cutting processing area A2, the dust removal station 40, the glue spraying processing area 20 and the plate area to be assembled A1 along the conveying direction. For the convenience of explanation, in this embodiment, the first plate 71 includes a first surface and a second surface relative to each other, and when on the first conveyor line A, the first surface faces upward to form an upper surface. Among them, after the first plate 71 is cut into a preset size by the cutting processing area A2, it enters the dust removal station 40, and after being cleaned by the roller brush 412, the first surface of the first plate 71 is sprayed by the glue spraying processing area 20 to form a first processed plate.

[0123] In the processing flow of the second conveyor line B, the second plate 72 is first placed on the second conveyor line B by manual or mechanical handling, and after the second plate 72 is pressed into a lower box by the lower box pressing device, it is transferred to the glue spraying equipment 21 on the second conveyor line B to spray the adhesive, and then transferred to the first station B11, the second station B12 and the third station B13 in sequence.

[0124] In the processing flow of the third conveyor line, the third plate 73 (rock wool) is first placed on the third roller frame 61C by manual or mechanical transportation, and is cut into a preset size in the cutting processing area and then conveyed to the second conveyor line B.

[0125] In the processing flow of the fourth conveyor line D, the fourth plate 74 is first placed on the fourth conveyor line D by manual or mechanical transport, and is transferred to the glue spraying device 21 on the fourth conveyor line D for spraying adhesive, and then transferred to the flipping workstation D1. Then, the fourth plate 74 on the flipping workstation D1 is flipped 180 degrees to the third station B13 of the second conveyor line B through the flipping device D2 between the fourth conveyor line D and the second conveyor line B.

[0126] It is worth noting that in the processing flow of the embodiment of the present application, the first processing board in the first storage area A11 is first moved to the first station B11 by manual transport, and the lower surface of the first plate 71 in the first processing board that is not sprayed with adhesive is attached to the adhesive on the second plate 72 (that is, attached to the lower box) to form a second processing board. Then, the second processing board and the third plate 73 are transported to the second station B12, and the third plate 73 is attached to the upper surface of the first plate 71 sprayed with adhesive in the second processing board to form a third processing board. After the third processing board is transported to the third station B13, the first processing board in the second storage area A12 is moved to the third station B13 by manual transport, and turned 180 degrees, so that the upper surface of the first plate 71 sprayed with adhesive in the first processing board faces downward, and is attached to the third plate 73 in the third processing board, so that the third plate 73 is sandwiched between the two first plates 71, and the first plate 71 and the third plate 73 are accommodated in the lower box (the second plate 72). Finally, the fourth plate 74 (upper box) on the fourth conveyor line D is driven to the second conveyor line B by the turning device D2, and is turned 180 degrees (such as Figure 8 As shown), the fourth plate 74 is placed with the adhesive sprayed on one side facing downward and attached to the topmost first plate 71 in the third processed plate, thereby being sealed with the second plate (lower box) to form a composite plate 80 (purification plate).

[0127] In some embodiments, a coding station B2 (such as Figure 2As shown). The coding workstation B2 is arranged behind the hot pressing processing area 50 and is provided with a laser processing device B21. After the composite board 80 is hot pressed in the hot pressing processing area 50, it is transferred to the coding workstation B2, and an identification mark is drawn on the surface of the composite board 80 by the laser processing device B21. For example, logos, texts, numbers, etc. are printed on the metal surface of the composite board 80, which can provide subsequent tracking, quality control, anti-counterfeiting and security, product information presentation or scanning, etc. (the purpose of coding the composite board 80 may be multifaceted, mainly depending on actual needs and industry standards).

[0128] It is worth noting that a finished product temporary storage area B3 (such as Figure 2 As shown), the above-mentioned automatic palletizing equipment 13 is arranged in the finished product temporary storage area B3, and the composite board 80 after coding can be taken and placed in the finished product temporary storage area B3. For example, the finished product temporary storage area B3 includes a first station B31 and a second station B32, and a detection conveying roller B33 is arranged on one side of the finished product temporary storage area B3. The automatic palletizing equipment 13 can stack the finished composite board 80 in a staggered manner at the first station B31 and the second station B32, or place it on the detection conveying roller B33 to be transferred to the test area for detection.

[0129] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
