Description

Technical Field

[0001] This invention relates to the field of cleanroom sandwich panel equipment technology, specifically to a continuous cleanroom sandwich panel production and processing equipment. Background Technology

[0002] Existing general-purpose cleanroom sandwich panels typically consist of an upper panel, a lower panel, and a core material. The panels are bonded together using sprayed adhesive and then heat-pressed for final curing. Most existing cleanroom sandwich panels are produced on assembly lines. However, the flipping and assembly of the glued panels still largely relies on manual rotation and positioning. Furthermore, existing cleanroom sandwich panels generally have a three-layer structure, requiring adhesive to be applied to both sides of the core panel and the inner sides of the upper and lower panels to prevent subsequent delamination. After adhesive application, the positioning and joining of the panels requires significant manual intervention. Due to the mass production on assembly lines and the large amount of manual intervention during flipping, the initial positioning of the sandwich panels still has some deviation. Consequently, after heat pressing, the sides of the sandwich panels need to be sanded again when applying adhesive tape, greatly reducing production efficiency and quality. Therefore, a continuous cleanroom sandwich panel production and processing equipment is needed to solve the problems mentioned above. Summary of the Invention

[0003] The purpose of this invention is to provide a continuous cleanroom sandwich panel production and processing equipment to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a continuous cleanroom sandwich panel production and processing equipment, comprising a docking base, a guide tray fixedly mounted on the upper part of the docking base by four sets of aluminum profile columns, a servo turntable fixedly mounted at the center of the upper part of the docking base, a servo motor fixedly mounted at the power input end of the servo turntable, and a support top plate fixedly mounted at the power output end of the servo turntable.

[0005] The material guiding and turning assembly consists of four sets, which are fixedly snapped together in a ring at equal intervals inside the guide plate. The material guiding and turning assembly is used to support and shape the sandwich panel.

[0006] The sheet material feeding assembly consists of three sets. The sheet material feeding assembly located at the initial feeding station has a lower steel plate equidistantly sliding and engaging inside. The sheet material feeding assembly located at the first gluing station has a core material plate equidistantly sliding and engaging inside. The sheet material feeding assembly located at the second gluing station has an upper steel plate equidistantly sliding and engaging inside. The sheet material feeding assembly is used for positioning and feeding.

[0007] The glue application assembly is fixedly installed at the center of the lower end face of the supporting top plate. The glue application assembly is used to apply glue to both sides of the first glue application station and the second glue application station.

[0008] The pre-pressing assembly is fixedly installed at the unloading station inside the supporting top plate. The pre-pressing assembly is used to pre-shape and press the lower steel plate, core plate and upper steel plate after the adhesive has been applied.

[0009] Specifically, the power output of the servo turntable drives four sets of material guiding and turning components to rotate intermittently at equal intervals through the guide plate. The plate feeding components at the three workstations sequentially feed the lower steel plate, core material plate and upper steel plate into the material guiding and turning components. The gluing component can cooperate with the feeding component to apply glue to the lower steel plate, core material plate and upper steel plate at the same time. After the glue is applied, the lower steel plate, core material plate and upper steel plate are shaped and composite pressed by the pre-pressing component.

[0010] Specifically, the material guiding and flipping assembly includes a support bracket, a swing cylinder fixedly mounted at the front of the support bracket via a cylinder seat, a plate alignment fixture rotatably engaged inside the support bracket via two sets of bearing seats, and a pen-shaped cylinder fixedly mounted at the bottom of the plate alignment fixture. The power output end of the pen-shaped cylinder drives the material pusher plate to move up and down inside the plate alignment fixture. Two sets of three-axis cylinders are installed inside the support bracket, and the power output end of the three-axis cylinders is adapted to the locking groove via a limiting plate to limit and engage both sides of the plate alignment fixture. A detection baffle is installed at the power input end of the plate alignment fixture, and two sets of proximity switches are installed inside the support bracket near the power input end of the plate alignment fixture.

[0011] Specifically, the swing cylinder drives the plate alignment fixture to rotate 180 degrees inside the support bracket through two sets of bearing seats. Two sets of proximity switches simultaneously detect the rotation position of the plate alignment fixture through detection baffles. Two sets of three-axis cylinders are inserted into the locking slots through limit plates to lock both sides of the plate alignment fixture. The pen-shaped cylinder pushes the composite bonded lower steel plate, core material plate and upper steel plate to slide and unload through the feeding push plate. The three-axis cylinders on both sides are inserted into the locking slots through limit plates to lock the plate alignment fixture, which can prevent tilting during subsequent pressing and improve the stability and accuracy of pressing the lower steel plate, core material plate and upper steel plate.

[0012] Specifically, the sheet material feeding assembly includes a sheet material bin, stepper motors fixedly mounted on both sides of the sheet material bin, a transmission shaft fixedly mounted on the power output end of the stepper motors, and an adjusting bolt rotatably engaged with the center of the transmission shaft. A lower baffle plate is fixedly engaged with the bottom of the transmission shaft, and an upper baffle plate is threadedly connected to the upper part of the transmission shaft via an adjusting bolt and an adjusting nut. A second proximity switch is fixedly engaged with the bottom of the sheet material bin, and an adhesive guide groove is provided at the bottom of the sheet material bin directly opposite the second proximity switch.

[0013] Specifically, the upper baffle and the lower baffle are arranged vertically, and the stepper motor drives the upper baffle and the transmission shaft synchronously to limit the material of the plate inside the plate material bin one by one. The adjusting bolt adjusts the distance between the upper baffle and the lower baffle through the adjusting nut, thereby adjusting the distance between the upper baffle and the lower baffle to facilitate the subsequent adaptation to the cutting of plates of different thicknesses.

[0014] Specifically, the adhesive application assembly includes a positioning bracket, a second servo motor fixedly mounted at the center of the upper surface of the positioning bracket, and a transmission gear fixedly engaged with the power output end of the second servo motor. The power output end of the second servo motor synchronously drives two sets of right-angled transmission racks to mesh and move through the transmission gear. Each set of transmission racks has a plate-type adhesive spray head fixedly mounted at its inner end. The bottom of the positioning bracket is slidably engaged with the two sets of transmission racks through two sets of dovetail sliders. Dovetail grooves are provided in the middle of the upper surface of each set of transmission racks. Each set of plate-type adhesive spray heads has an adhesive guide groove for docking at its rear adhesive inlet.

[0015] Specifically, the two sets of plate-type glue spray heads are adapted to the dovetail slider and dovetail groove and are slidably engaged at the bottom of the positioning bracket. The servo motor 2 drives the two sets of vertically interlaced transmission racks to move at the bottom of the positioning bracket through the transmission gear. The two sets of transmission racks drive the plate-type glue spray heads to slide into the plate material compartment through the glue guide groove. The proximity switch 2 is used to detect the position of the plate-type glue spray heads. The two sets of transmission racks are arranged vertically interlaced on the side of the transmission gear, which can improve the stability of the transmission and improve the space utilization.

[0016] Specifically, the pre-press assembly includes a fixed base, a servo electric cylinder fixedly installed at the center of the upper part of the fixed base, and a guide slide fixedly engaged with the power output end of the servo electric cylinder. The lower part of the guide slide is elastically engaged with a pressing mold base through four sets of buffer springs and a linear slide shaft, and the upper end face of the pressing mold base is fixedly connected to the bottom of the linear slide shaft through a spoke-type pressure sensor.

[0017] Specifically, the servo electric cylinder drives the pressing mold base to elastically press the lower steel plate, core material plate, and upper steel plate inside the plate alignment fixture through the guide slide, buffer spring, and linear slide shaft. The four sets of spoke-type pressure sensors detect the pressing force of the pressing mold base through the buffer spring. The four sets of spoke-type pressure sensors can not only improve the accuracy of the pressing limit pressure detection, but also prevent the pressure from exceeding the limit, thereby improving the stability of pressing and shaping the lower steel plate, core material plate, and upper steel plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention is a multi-station compact rotary sandwich panel processing equipment. The servo turntable can intermittently rotate and guide the material through the guide tray, so that the three-station sheet material feeding components can sequentially and orderly guide the lower steel plate, core material plate and upper steel plate into the sheet alignment fixture for composite. At the same time, during the composite process, the adhesive application components can simultaneously spray the sheets together, which effectively improves the automation level of the equipment in guiding, spraying, composite and press-fitting the sheet material, and thus simultaneously improves the regularity of the lower steel plate, core material plate and upper steel plate after hot pressing.

[0020] 2. This invention is an adaptive adjustable device. When adaptively composited sandwich panels of different lengths and widths, a compensation plate of the corresponding length can be introduced into the panel material hopper. The panel material hopper can then guide sandwich panel pieces of different lengths. At the same time, the adjusting bolt can adjust the distance between the upper and lower baffle plates by connecting with the adjusting nut through threads. The dual length and width adjustment structure can effectively improve the adaptability of the device to process and composite panels of different lengths, widths, and thicknesses.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] The invention will be further described below with reference to the accompanying drawings.

[0041] Example 1

[0042] Please see Figure 1-2 One embodiment of the present invention provides a continuous cleanroom sandwich panel production and processing equipment, comprising a docking base 1, a guide tray 10 fixedly mounted on the upper part of the docking base 1 by four sets of aluminum profile columns 9, a servo turntable 12 fixedly mounted at the center of the upper part of the docking base 1, a servo motor 13 fixedly mounted at the power input end of the servo turntable 12, and a support top plate 11 fixedly mounted at the power output end of the servo turntable 12.

[0043] The model of the servo turntable 12 is ZJ-LW300-servo turntable, and the model of the servo motor 13 that is matched with it is 130mm servo motor_130ST-M040. The servo turntable 12 can perform closed-loop control, and the repeated positioning and angular positioning errors are extremely small, which can improve the accuracy of guiding and positioning the lower steel plate 6, core plate 7 and upper steel plate 8.

[0044] The material guiding and turning assembly 2 has four sets. The four sets of material guiding and turning assemblies 2 are fixedly snapped into the inside of the guide plate 10 in a ring at equal intervals. The material guiding and turning assembly 2 is used to support and shape the sandwich panel.

[0045] The sheet material feeding assembly 3 has three sets. The sheet material feeding assembly 3 located at the initial feeding station has a lower steel plate 6 equidistantly sliding and engaging inside. The sheet material feeding assembly 3 located at the first gluing station has a core material plate 7 equidistantly sliding and engaging inside. The sheet material feeding assembly 3 located at the second gluing station has an upper steel plate 8 equidistantly sliding and engaging inside. The sheet material feeding assembly 3 is used for positioning and feeding.

[0046] The aforementioned cleanroom sandwich panel is composed of a lower steel plate 6, a core material plate 7, and an upper steel plate 8. The lower steel plate 6 and the upper steel plate 8 are color steel plates with a thickness of 0.5 mm, and the core material plate 7 has a core material thickness of 50 mm.

[0047] The glue application assembly 4 is fixedly installed at the center of the lower end face of the supporting top plate 11. The glue application assembly 4 is used to apply glue to both sides of the first glue application station and the second glue application station.

[0048] Pre-pressing assembly 5 is fixedly installed at the unloading station inside the supporting top plate 11. The pre-pressing assembly 5 is used to pre-shape and press the lower steel plate 6, core material plate 7 and upper steel plate 8 after the glue has been applied.

[0049] When applying adhesive to the lower steel plate 6, core plate 7, and upper steel plate 8, the core plate 7 is fully coated on both the top and bottom surfaces, while the lower steel plate 6 is coated on the top surface and the upper steel plate 8 is coated on the bottom surface. This improves the wettability of the adhesive on the plates and prevents them from falling off later.

[0050] The power output end of the servo turntable 12 drives four sets of material guiding and flipping components 2 to rotate intermittently at equal intervals through the guide plate 10. The plate feeding component 3 at the third station sequentially feeds the lower steel plate 6, core material plate 7 and upper steel plate 8 into the material guiding and flipping component 2. The gluing component 4 can cooperate with the feeding component 3 to apply glue to the lower steel plate 6, core material plate 7 and upper steel plate 8. After the glue is applied, the lower steel plate 6, core material plate 7 and upper steel plate 8 are shaped and composite pressed by the pre-pressing component 5.

[0051] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The material guiding and flipping assembly 2 includes a support bracket 25, a swing cylinder 26 fixedly mounted at the front of the support bracket 25 via a cylinder seat 28, a plate alignment fixture 27 rotatably engaged inside the support bracket 25 via two sets of bearing seats 212, and a pen-shaped cylinder 24 fixedly mounted at the bottom of the plate alignment fixture 27.

[0052] Among them, the swing cylinder 26 is an MSQ gear and rack swing cylinder, which can effectively improve the stability of the plate alignment fixture 27 during the feeding and flipping inside the support bracket 25.

[0053] The model number of the pen-shaped cylinder 24 is: MSBL aluminum alloy mini cylinder [MSBL20×50-SUFA].

[0054] The power output end of the pen-shaped cylinder 24 drives the unloading push plate 21 to move up and down inside the plate alignment fixture 27. Two sets of three-axis cylinders 23 are set inside the support bracket 25. The power output end of the three-axis cylinder 23 is adapted to the locking slot 211 through the limiting plate 22 to limit and lock the two sides of the plate alignment fixture 27. The three-axis cylinder 23 has its own guide shaft, which can improve the stability of the limiting plate 22 locking into the locking slot 211. The model of the three-axis cylinder 23 is TCL.

[0055] A detection baffle 210 is provided at the power input end of the plate alignment fixture 27, and two sets of proximity switches 29 are provided inside the support base 25 near the power input end of the plate alignment fixture 27. The proximity switches 29 are used to detect the position of the detection baffle 210, thereby determining the flip position of the plate alignment fixture 27 in real time and improving the accuracy of subsequent flipping and unloading. The models of proximity switches 29 and 38 are C-M8-CAP-04.

[0056] like Figure 9 , Figure 10 and Figure 11 The plate feeding assembly 3 includes a plate material bin 31, a stepper motor 32 fixedly installed on both sides of the plate material bin 31, a transmission shaft 37 fixedly installed at the power output end of the stepper motor 32, and an adjusting bolt 35 rotatably connected to the center of the transmission shaft 37. The plate material bin 31 is also provided with a viewing window, which can facilitate the observation of the remaining material and improve the convenience of feeding the lower steel plate 6, core plate 7 and upper steel plate 8.

[0057] The model number of stepper motor 32 is: ZJT01-1.8-S-4-L41;

[0058] The bottom of the transmission shaft 37 is fixedly connected to a lower baffle plate 36, which is preferably fixed to the outside of the transmission shaft 37 by locking bolts.

[0059] An upper baffle plate 34 is located on the upper part of the transmission shaft 37 and is connected by adjusting bolts 35 and adjusting nuts 33 through threaded connection.

[0060] The upper edge of the upper baffle plate 34 is provided with a positioning rounded corner, which can improve the stability of lifting and limiting the upper plate.

[0061] A proximity switch 38 is fixedly attached to the bottom of the board material storage 31, and an adhesive guide groove 39 is provided at the bottom of the board material storage 31 directly opposite the proximity switch 38.

[0062] like Figure 12 , Figure 13 and Figure 14 The adhesive application assembly 4 includes a positioning bracket 42, a second servo motor 41 fixedly mounted at the center of the upper surface of the positioning bracket 42, and a transmission gear 45 fixedly engaged with the power output end of the second servo motor 41.

[0063] The model number of the servo motor 241 is: MHMF022L1U2M;

[0064] The power output end of the servo motor 41 synchronously drives two sets of right-angled transmission racks 44 to mesh and move through the transmission gear 45. Each set of transmission racks 44 has a plate-type glue spray head 47 fixedly installed at its internal end. The bottom of the positioning bracket 42 is slidably engaged with the two sets of transmission racks 44 through two sets of dovetail sliders 48. Dovetail grooves 43 are opened in the middle of the upper end face of each set of transmission racks 44. Each set of plate-type glue spray heads 47 has a glue guide groove 46 for docking at the rear glue inlet.

[0065] like Figure 15 The pre-press assembly 5 includes a fixed base 52, a servo electric cylinder 51 fixedly installed at the center of the upper part of the fixed base 52, and a guide slide 53 fixedly snapped onto the power output end of the servo electric cylinder 51. The model of the servo electric cylinder 51 is: EMB30-10-100-P10-FF-FM-FCM-AR-750W.

[0066] The lower part of the guide slide 53 is elastically and slidably connected to the pressing mold base 55 through four sets of buffer springs 56 and linear slide shaft 57. The upper end face of the pressing mold base 55 is fixedly connected to the bottom of the linear slide shaft 57 through the spoke-type pressure sensor 54. The model of the spoke-type pressure sensor 54 is: ECA-LCF2 spoke-type pressure sensor.

[0067] As shown in the figure, the swing cylinder 26 drives the plate alignment fixture 27 to rotate 180 degrees inside the support bracket 25 through two sets of bearing seats 212. The two sets of bearing seats 212 inside the support bracket 25 can improve the stability of locking and limiting the plate alignment fixture 27, and at the same time improve the ease of installation. The swing cylinder 26 can improve the stability of the plate alignment fixture 27 rotating 180 degrees.

[0068] Furthermore, the two sets of proximity switches 29 synchronously detect the flipping position of the plate alignment fixture 27 through the detection baffle 210.

[0069] Two sets of three-axis cylinders 23 are inserted into the locking slots 211 through the limiting plate 22 to lock both sides of the plate alignment fixture 27. The three-axis cylinders 23 on both sides are inserted into the locking slots 211 through the limiting plate 22 to lock the plate alignment fixture 27, which can prevent tilting during subsequent pressing and improve the stability and accuracy of pressing the lower steel plate 6, core plate 7 and upper steel plate 8.

[0070] The pen-shaped cylinder 24 pushes the composite bonded lower steel plate 6, core material plate 7 and upper steel plate 8 to slide and feed through the feeding pusher plate 21, which can improve the stability of the subsequent feeding of the lower steel plate 6, core material plate 7 and upper steel plate 8.

[0071] like Figure 9 The upper baffle plate 34 and the lower baffle plate 36 are vertically arranged, and the stepper motor 32 drives the upper baffle plate 34 and the transmission shaft 37 to limit the material of the plates in the plate material bin 31 one by one. When the plates are being cut one by one, the stepper motor 32 can drive the upper baffle plate 34 and the lower baffle plate 36 to rotate 90 degrees, so that the lower baffle plate 36 releases the limit on the plate, and the upper baffle plate 34 can be guided to the bottom of the second group of plates through the positioning rounded corner to complete the synchronous limit, thereby improving the stability of the plates being cut one by one.

[0072] The adjusting bolt 35 adjusts the distance between the upper baffle plate 34 and the lower baffle plate 36 through the adjusting nut 33. The adjusting bolt 35 can adjust the distance between the upper baffle plate 34 and the lower baffle plate 36 through the threaded connection with the adjusting nut 33, which facilitates the subsequent adaptation to the blanking of plates of different thicknesses.

[0073] like Figure 12 , Figure 13 and Figure 14 Two sets of plate-type glue spray heads 47 are adapted to dovetail sliders 48 and dovetail grooves 43 and are slidably engaged at the bottom of the positioning base 42. The two sets of dovetail sliders 48 can provide sufficient limiting basis for the front and rear displacement of the plate-type glue spray head 47 through the dovetail grooves 43, thereby improving the stability of the front and rear displacement of the plate-type glue spray head 47.

[0074] like Figure 3 Furthermore, the servo motor 41 synchronously drives two sets of interlocking transmission racks 44 to move at the bottom of the positioning bracket 42 via the transmission gear 45.

[0075] Two sets of transmission racks 44 are arranged alternately on the side of the transmission gear 45, which can improve the stability of transmission and improve the utilization of space.

[0076] Two sets of transmission racks 44 drive the plate-type glue spray head 47 to slide into the plate material bin 31 through the glue coating guide groove 39, and the proximity switch 38 is used to detect the position of the plate-type glue spray head 47, which can improve the stability of the subsequent glue coating of the plate-type glue spray head 47 into the plate material bin 31.

[0077] like Figure 15 The servo electric cylinder 51 drives the pressing mold base 55 to elastically press the lower steel plate 6, core material plate 7 and upper steel plate 8 inside the plate alignment fixture 27 through the guide slide 53, buffer spring 56 and linear slide shaft 57. During pressing, the pressing mold base 55 first contacts the top of the lower steel plate 6, core material plate 7 and upper steel plate 8 inside the plate alignment fixture 27. Then the servo electric cylinder 51 drives the guide slide 53 to move down, so that the guide slide 53 continuously applies elastic pressure to the pressing mold base 55 through the buffer spring 56 until the four sets of spoke-type pressure sensors 54 sense the preset pressure value. At this time, the pressing is completed. The four sets of spoke-type pressure sensors 54 can not only improve the accuracy of the pressure detection of the pressing limit, but also prevent the pressure from exceeding the limit, and improve the stability of pressing and shaping the lower steel plate 6, core material plate 7 and upper steel plate 8.

[0078] Furthermore, the four sets of spoke-type pressure sensors 54 detect the pressing force of the pressing mold base 55 through the buffer spring 56.

[0079] Working principle: such as Figure 2 Before laminating the cleanroom sandwich panels, workers can sequentially guide the lower steel plate 6, core material plate 7, and upper steel plate 8 of the cleanroom sandwich panels into the material storage bin 31 above the initial station, the first gluing station, and the second gluing station. When loading the pre-pressed assembly 5, lower steel plate 6, and core material plate 7, the viewing window on the side of the material storage bin 31 allows for easy and gradual insertion of the panels into the bin, preventing impact on the upper baffle plate 34 and lower baffle plate 36, and enabling quick identification of excess material. Figure 13 The staff can insert the external glue supply head into the glue guide groove 46. The glue supply head can supply high pressure glue to the plate spray head 47. Its glue supply hose is routed through the empty groove in the middle of the servo turntable 12.

[0080] like Figure 1 During the composite production of cleanroom sandwich panels, operators can activate servo motor 13 via an external touchscreen module. Servo motor 13 then powers the servo turntable 12, causing it to intermittently rotate the guide tray 10 90 degrees in a cyclical manner. Figure 1 and Figure 9At this time, the external touch screen module can start the stepper motor 32 through the PLC. The stepper motor 32 can drive the transmission shaft 37 to rotate 90 degrees, so that the transmission shaft 37 can synchronously drive the upper baffle plate 34 and the lower baffle plate 36 to rotate 90 degrees. At this time, the upper baffle plate 34 can block the second set of lower steel plates 6. At the same time, the upper baffle plate 34 can release the limit of the last set of lower steel plates 6, so that the lower steel plates 6 can fall directly into the plate alignment fixture 27 along the guide at the bottom of the plate material bin 31. The plate alignment fixture 27 is equipped with a proximity switch for detecting the plate's arrival. After the lower steel plate 6 arrives, the proximity switch feeds back an electrical signal to the touch screen module. Then, the touch screen module continues to control the servo turntable 12 through the servo motor 13 to drive the guide plate 10 to rotate to the next station. When the guide plate 10 drives the plate alignment fixture 27 and the lower steel plate 6 to the first glue application station, at this time... Figure 12 The external touchscreen module can activate servo motor 41. Servo motor 41 can be connected to two sets of transmission racks 44 via transmission gear 45, thereby driving the plate-type glue spray head 47 to move towards the plate material bin 31 of the first glue application station, and then... Figure 9 and Figure 12 The plate-type glue spray head 47 can be guided into the plate material bin 31 through the aluminum profile column 9. When the plate-type glue spray head 47 is completely guided into the bottom of the plate material bin 31, the proximity switch 38 can detect the position of the plate-type glue spray head 47 and then feed back an electrical signal to the touch screen module. The touch screen module then activates the external glue supply module, which guides the high-pressure glue through the glue supply line and glue supply head into the plate-type glue spray head 47 through the glue guide groove 46. At this time, the plate-type glue spray head 47 located inside the plate material bin 31 can simultaneously spray glue onto the bottom of the core material plate 7 and the top of the lower steel plate 6. After the glue spraying is completed, the plate-type glue spray head 47 resets and repeats the unloading steps of the plate feeding assembly 3. Machine 32 guides the glued core board 7 into the board alignment fixture 27 via the upper baffle plate 34 and the lower baffle plate 36, allowing the core board 7 to be bonded with the lower steel plate 6. Then, the guide tray 10 continues to move the board alignment fixture 27, the lower steel plate 6, and the core board 7 to the second glue application station. At this point, the glue application steps of the first station are repeated. The board-type glue spray head 47 can simultaneously spray glue onto the bottom of the upper steel plate 8 and the top of the core board 7. Then, guided by the upper baffle plate 34 and the lower baffle plate 36, the upper steel plate 8 continues to bond with the top of the core board 7. The board alignment fixture 27 automatically aligns the sides of the bonded lower steel plate 6, core board 7, and upper steel plate 8.

[0081] like Figure 1 and Figure 15The aforementioned guide tray 10 can move the plate alignment fixture 27, lower steel plate 6, core material plate 7, and upper steel plate 8 to the bottom of the pre-pressing assembly 5. At this time, the external touch screen module can activate the servo electric cylinder 51. The servo electric cylinder 51 can synchronously drive the pressing mold base 55 to move downward through the guide slide 53, so that the pressing mold base 55 can stably press against the upper part of the lower steel plate 6, core material plate 7, and upper steel plate 8 on the plate alignment fixture 27. The four sets of buffer springs 56 can feed back the pressure value to the external touch screen module through the spoke-type pressure sensor 54 to prevent the servo electric cylinder 51 from pressing too far, causing damage to the plate or the plate alignment fixture 27. After the rapid pressing and pressure holding is completed, the servo electric cylinder 51 drives the pressing mold base 55 to reset. At this time, if Figure 3 , Figure 4 and Figure 5 The external touch screen module can first activate two sets of three-axis cylinders 23 through the corresponding solenoid valve, so that the three-axis cylinders 23 can release the locking limit of 274 through the limit plate 22. Then the swing cylinder 26 can drive the unloading push plate 21 to swing 180 degrees. At the same time, when the swing reaches the bottom, the pen-shaped cylinder 24 can push out the lower steel plate 6, core material plate 7 and upper steel plate 8 that have been properly pressed inside the plate alignment fixture 27 through the unloading push plate 21. The unloaded lower steel plate 6, core material plate 7 and upper steel plate 8 can be exported through the conveyor line to facilitate the final hot pressing composite process.

[0082] If it is necessary to process cleanroom panels of different lengths and widths, the staff can guide the corresponding length of the compensation plate into the panel material bin 31, so that the panel material bin 31 can guide the sandwich panels of different lengths. Figure 9 and Figure 10 Workers can insert tools into the bottom of the adjusting bolt 35 and adjust the distance between the upper baffle plate 34 and the lower baffle plate 36 by rotating the adjusting bolt 35, so as to facilitate the individual cutting of plates of different thicknesses.

[0083] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
