[0002] Composite panels are formed by sandwiching a core material between two metal plates, such as cleanroom panels and insulation panels. By using metal plates of different materials and core materials of different materials, composite panels can have one or more functions such as fire resistance, heat insulation, dust prevention, antistatic properties, and antibacterial properties.

[0003] In existing technologies, when producing composite panels, the core material needs to be cut and then placed into the frame of the composite panel for assembly. However, when the core material is cut near the end, the cut-off pieces are unusable and need to be discarded, resulting in waste.

[0058] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0060] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features.

[0061] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0062] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A exists, A and B exist simultaneously, and B exists. In addition, the character " / " in this document generally indicates that the related objects before and after it have an "or" relationship.

[0063] Composite panels are formed by sandwiching a core material between two metal plates. They are widely used, with cleanroom panels being a prime example. They are widely applied in cleanroom engineering fields with stringent indoor environmental requirements, such as electronics, pharmaceuticals, food, biology, aerospace, precision instrument manufacturing, and scientific research.

[0064] The production of cleanroom panels has always been semi-manual, especially the assembly of the metal plates, frames, and core materials. Specifically, the cleanroom panels are first processed using equipment to shape the metal plates into a box (hereinafter referred to as the upper and lower boxes), and the frame is processed to meet the size requirements for placing the metal plates into the box. Then, they are assembled manually.

[0065] The manual assembly process includes: the worker first lifts the lower box and places it on the designated workstation, then puts the frame into the lower box; next, the worker takes the core material (such as rock wool blocks) and assembles it into the frame of the lower box. In order to fill the space inside the frame, the core material needs to be cut until the frame is full; finally, the worker picks up the upper box and puts it on top of the lower box, completely wrapping the core material and frame, and sends it into the molding machine for extrusion molding, so that the upper and lower boxes are firmly connected together, and the frame and core material are firmly wrapped in the middle.

[0066] As can be seen above, in manual production, workers need to cut the core material. When the cutting position is near the end of the core material, the cut-off material is no longer suitable as core material and can only be treated as waste, resulting in waste. At the same time, manual production is not only time-consuming and labor-intensive, but also cannot achieve continuous production.

[0067] To solve the above problems, the inventors found it necessary to automate the production of composite panels, including automatically transporting metal sheets into upper and lower boxes along the production line, automatically forming core material (to fit the dimensions of the frame) and placing it into the production line for automatic transport, automatically placing the frame into the production line for transport, and automatically assembling the upper and lower boxes, core material and frame on the production line.

[0068] However, when continuously and automatically molding core materials, the same problem as manual work still exists: the core materials need to be cut, which leads to waste of material scraps.

[0069] Therefore, this application provides a core material end-spraying mechanism to spray adhesive onto the ends of the core material raw material. Then, a feeding machine can sequentially feed the sprayed core material raw material into the production conveyor line, allowing the core material raw material to be pasted end-to-end sequentially to form a continuously extending core material. Then, an automatic cutting device is used to cut the core material, enabling continuous and automated production of core materials that meet dimensional requirements. This not only achieves continuous and automated core material forming but also avoids material waste. The following are specific embodiments:

[0070] Example 1

[0071] like Figures 1-4 As shown, this application provides a core material end glue spraying mechanism, including: a material storage section S1 and a glue spraying section S2;

[0072] The storage section S1 is used to store the core material raw material S3, and the top of the storage section S1 has a discharge port 10; the glue spraying section S2 includes a linear drive unit 20 and a glue gun 21, the linear drive unit 20 is disposed on one side edge of the discharge port 10, and the glue gun 21 is connected to the linear drive unit 20; wherein, the linear drive unit 20 can drive the glue gun 21 to reciprocate along one side edge of the discharge port 10, for spraying glue onto the end of the core material raw material S3 that is raised and protrudes from the discharge port 10.

[0073] Specifically, the storage unit S1 is a device used to store the core material raw material S3. The storage unit S1 not only needs to be able to store a certain amount of core material raw material S3 in layers, but also needs to be able to push the stored core material raw material S3 out from the top discharge port 10 so that after end-spraying, the core material raw material S3 can be fed into the composite board production line by the feeding machine. For example, the storage unit S1 can be a temporary storage device for core material raw material S3 in the composite board production line.

[0074] The glue spraying unit S2 is a structure used to spray glue onto the end of the core material S3 protruding from the discharge port 10. The linear drive unit 20 of the glue spraying unit S2 can be fixedly or detachably installed on one side edge of the discharge port 10 of the storage unit S1. It can be welded, bolted, or clamped and fixed by a clamping component. The linear drive unit 20 can be any device that can drive the glue gun 21 to reciprocate in a straight line, such as a linear motor, cylinder, hydraulic cylinder, synchronous belt, etc. Since the end of the core material S3 is linear, and the discharge port 10 of the storage unit S1 is also linear, the linear drive unit 20 is arranged parallel to one side edge of the discharge port 10 so that the glue gun 21 can move in a straight line to spray glue onto the end of the core material S3.

[0075] The glue gun 21 is connected to and driven by the linear drive unit 20. The glue nozzle of the glue gun 21 needs to face the discharge port 10. The glue gun 21 is a component that can be connected to a pressure glue supply device. It can be connected to the pressure glue supply device through a tube and disperses the glue through the glue nozzle, that is, disperses it onto the end of the core material S3. The glue gun 21 can be purchased.

[0076] Compared to existing technologies, the core material end-spraying mechanism provided in this application can spray adhesive onto the ends of the core material raw material S3 ejected from the storage section S1, thereby allowing the core material raw material S3 to be bonded end-to-end sequentially to form a continuously extending core material. Then, it can be cut according to the required length of the core material for the composite board, without generating any scrap or waste. Furthermore, the core material end-spraying mechanism provided in this application automatically sprays adhesive onto the ends of the core material raw material S3, effectively saving manpower and improving work efficiency. It can also be combined with a feeding machine to form a feeding device, allowing the glued core material raw material S3 to be placed sequentially on the production line, enabling the core material raw material S3 to be bonded end-to-end sequentially. This promotes automated core material forming and can further be combined with other automated production equipment to form a composite board production line, greatly improving the production efficiency of composite boards.

[0077] like Figures 1-4 As shown, in a specific implementation, the glue spraying unit S2 further includes: a bracket 22, the first end of the bracket 22 is connected to the side of the material storage unit S1, the second end of the bracket 22 is away from the first end, the linear drive unit 20 is connected to the second end of the bracket 22, and the linear drive unit 20 and the glue gun 21 are both located above the plane where the end of the discharge port 10 is located.

[0078] Specifically, the bracket 22 can be of any form, such as a truss structure, a leg form, a support plate form, etc. That is, the bracket 22 is not specifically structurally limited, as long as it can connect between the material storage section S1 and the linear drive unit 20, enabling them to connect and be positioned relative to each other. It should be noted that after connection via the bracket 22, the linear drive unit 20 and the glue gun 21 are at a certain distance relative to the discharge port 10. This distance is set according to the glue spraying distance of the glue gun 21 (the distance to ensure good glue spraying onto the end of the core material S3). Simultaneously, it is necessary to ensure that the glue gun 21 and the linear drive unit 20 are located above the plane where the end of the discharge port 10 is located, so that the glue gun 21 can be directly aligned with the end of the core material S3 protruding from the discharge port 10, ensuring effective glue spraying.

[0079] like Figures 1-4 As shown, in a specific implementation, the linear drive unit 20 includes: a linear guide structure 201 and a drive motor 202;

[0080] The linear guide structure 201 is connected to the upper part of the second end of the bracket 22 and is parallel to one side edge of the discharge port 10; the drive motor 202 is mounted on the linear guide structure 201 and connected to the glue gun 21; the glue gun 21 is slidably connected to the linear guide structure 201; wherein, the glue gun 21 is located on the side of the linear guide structure 201 facing the discharge port 10, and the glue nozzle of the glue gun 21 faces the side of the discharge port 10.

[0081] Specifically, the bracket 22 can be horizontally connected to one side of the discharge port 10, and the upper part of the bracket 22 can be flush with the plane of the end of the discharge port 10. The linear drive unit 20 can be a synchronous belt module, and the linear guide structure 201 can be fixed to the upper part of the second end of the bracket 22 by bolts. At this time, the linear guide structure 201 is located above the plane of the end of the discharge port 10, the drive motor 202 is located above the plane of the end of the discharge port 10, and the glue gun 21 connected to the linear guide structure 201 is also located above the plane of the end of the discharge port 10.

[0082] The linear guide structure 201 ensures that the glue gun 21 slides smoothly along a straight line, while the drive motor 202 ensures that the moving speed of the glue gun 21 is controllable.

[0083] Furthermore, the linear drive unit 20 also includes: a mounting bracket 203;

[0084] The mounting bracket 203 includes a support body 2031 and a connecting body 2032. The glue gun 21 is mounted on the support body 2031. One side of the support body 2031 is connected to the connecting body 2032. The connecting body 2032 is connected to the slider 204. The slider 204 is slidably connected to the linear guide structure 201. At least one elongated hole 2033 is formed on the connecting body 2032 along the vertical direction. The elongated hole 2033 penetrates the connecting body 2032. The connecting body 2032 is bolted to the slider 204 through the elongated hole 2033.

[0085] Specifically, the mounting bracket 203 can be a bent plate structure, that is, the support body 2031 can be a plate, and the connecting body 2032 can also be a plate, but it is not limited to a plate structure. The mounting bracket 203 can also be a rod structure. In this application, it is preferred to use a plate to make the mounting bracket 203. The support body 2031 can be a horizontally set plate. The glue gun 21 can be bolted to the upper surface of the support body 2031. The connecting body 2032 and the support body 2031 can be an integral structure. The mounting bracket 203 structure is obtained by bending (e.g., bending 90 degrees), or one end of the plate of the connecting body 2032 can be connected to one side of the support body 2031 (e.g., welding, and the connection angle can also be 90 degrees).

[0086] The connecting body 2032 has a through hole 2033 extending along its length on its plate. The hole 2033 can be screwed into the bolt to connect to the slider 204 of the linear guide structure 201. The distance between the support body 2031 and the plane at the end of the outlet 10 can be adjusted by adjusting the connection position between the hole 2033 and the slider 204. In other words, the distance between the glue gun 21 and the plane at the end of the outlet 10 can be adjusted so that the glue gun 21 can be adjusted to be positioned directly opposite the end of the core material S3 protruding from the outlet 10.

[0087] In a specific implementation, the axis of the glue gun 21's spray nozzle forms an angle of -30 degrees to 30 degrees with the horizontal direction from the second end to the first end of the bracket 22 in the vertical plane.

[0088] Specifically, by setting the axis of the glue gun 21's nozzle at an angle of -30 to 30 degrees with the horizontal direction from the second end to the first end of the bracket 22, the angle can be set to 0 degrees when the glue gun 21 is spraying glue directly at the end of the core material S3. When the glue gun 21 is spraying glue at a downward angle towards the end of the core material S3, the angle can be set to -30 to 0 degrees (or larger, depending on actual needs). When the glue gun 21 is spraying glue at an upward angle towards the end of the core material S3, the angle can be set to 0 to 30 degrees (or larger, depending on actual needs).

[0089] like Figures 1-4 As shown, in a specific implementation, the glue spraying section S2 further includes a baffle 23, which is disposed above the bracket 22, located between the first and second ends of the bracket 22, and connected to the top of the discharge port 10.

[0090] Specifically, the baffle 23 is positioned above the horizontal bracket 22. It can serve as a glue blocker during glue spraying, preventing the sprayed glue from passing through the bracket 22 and falling below. It can also make the area above the bracket 22 a flat plate, making it easier to observe the working status of the glue gun 21 positioned above the baffle 23 and to facilitate cleaning.

[0091] like Figures 1-3 As shown, in another embodiment, the core material end adhesive spraying mechanism further includes: a glue gun cleaning and shielding section S4;

[0092] The glue gun cleaning shield S4 is installed at one end of the discharge port 10 where the linear drive unit 20 is located, and is used to receive the liquid sprayed out when cleaning the glue gun 21.

[0093] The glue gun cleaning shielding part S4 includes: a tank body 40 and a drain connector 41. The tank body 40 is a cylindrical shape with one end open, and the opening faces the linear drive unit 20. The bottom plate of the tank body 40 extends away from the opening and is turned up to form a liquid collection tank. The drain connector 41 is provided at the bottom of the liquid collection tank and is connected to the liquid collection tank.

[0094] Specifically, after the glue gun 21 finishes spraying glue, it needs to be cleaned with solvent. Since the solvent needs to be sprayed from the glue gun nozzle, the glue gun cleaning shield S4 can collect the solvent and prevent contamination of the equipment and core material S3.

[0095] The overall shape of the tank 40 of the glue gun cleaning shielding part S4 can be a cone shape, and the bottom plate of the tank 40 can be tilted downward so that the sprayed solvent liquid can flow out quickly and be discharged through the drain connector 41. The drain connector 41 can be connected to a pipe and discharged into a collection bucket or collection pool through the pipe.

[0096] like Figures 1-3 As shown, in another embodiment, the storage unit S1 can be a conventionally used silo, and may include:

[0097] 11. Warehouse body; 12. First propulsion mechanism; 13. Second propulsion mechanism;

[0098] The hopper 11 includes a collection hopper and a feeding hopper connected together. The collection hopper is used to hold the stacked core material raw material S3. The first pushing mechanism 12 is located on the side of the collection hopper away from the feeding hopper of the hopper 11. The first pushing mechanism 12 can push the core material raw material S3 in the collection hopper into the feeding hopper. The bottom of the feeding hopper is provided with the second pushing mechanism 13, and the top is the discharge port 10. The second pushing mechanism 13 can push the stacked core material raw material S3 out of the discharge port 10.

[0099] Specifically, the hopper 11 can be a rectangular shell with an open top, and the shell is divided into a collection hopper and a feeding hopper along the length direction. An opening is provided on the side wall of the collection hopper so that the stacked core material raw materials S3 can be fed into the collection hopper through the opening. Then, the first pushing mechanism 12 can push the stacked core material raw materials S3 into the feeding hopper. A second pushing mechanism 13 is provided at the bottom of the feeding hopper so that the core material raw materials S3 can be pushed out of the discharge port 10 one, two or more layers in succession. The glue gun 21 can then spray glue on one layer of core material raw materials S3, or spray glue on two or more layers of core material raw materials S3 at the same time.

[0100] Example 2

[0101] like Figure 5 As shown, this application provides a feeding device, including: a core material end glue spraying mechanism and a core material raw material feeding machine S5;

[0102] The core material end adhesive spraying mechanism includes: a material storage section S1 and an adhesive spraying section S2.

[0103] The storage section S1 is used to store the core material raw material S3, and the top of the storage section S1 has a discharge port 10; it includes a linear drive unit 20 and a glue gun 21, the linear drive unit 20 is disposed on one side edge of the discharge port 10, and the glue gun 21 is connected to the linear drive unit 20; wherein, the linear drive unit 20 can drive the glue gun 21 to reciprocate along one side edge of the discharge port 10, for spraying glue onto the end of the core material raw material S3 that is raised and protrudes from the discharge port 10;

[0104] The core material feeder S5 has a horizontally arranged gripping station and a discharging station. The core material end glue spraying mechanism is located below the core material feeder S5, and the discharge port 10 of the storage section S1 of the core material end glue spraying mechanism is directly opposite the gripping station.

[0105] Specifically, the core material end glue spraying mechanism described in this embodiment two can directly use the core material end glue spraying mechanism provided in embodiment one above. For the specific implementation structure, please refer to the relevant content described in embodiment one above, which will not be repeated here.

[0106] The core material feeder S5 is an existing piece of equipment. As described above, it has a gripping station and a discharging station. At the gripping station, the core material feeder S5 can grab a layer of core material S3 protruding from the outlet 10 of the storage section S1. That is, it can grab a layer of core material S3 with glue sprayed on its end, and then carry and move it to the discharging station to realize the transfer of the glued core material S3. After the glued core material S3 is transferred to the production conveyor line in sequence, the adjacent core material S3 can be bonded together end to end (this can be achieved by making the speed of the core material S3 entering the production conveyor line later greater than the speed of the core material S3 entering the production conveyor line earlier, so that the two collide and bond).

[0107] Compared to existing technologies, the feeding device provided in this application can spray adhesive onto the ends of the core material raw material S3 ejected from the storage section S1 and transfer it to the production conveyor line, so that the core material raw material S3 is bonded end to end in sequence to form a continuously extending core material. Then, it can be cut according to the required size and length of the core material for the composite board. At this time, the cutting will not generate material ends, that is, no waste will be generated, thus avoiding waste. At the same time, the feeding device provided in this application automatically sprays adhesive and feeds the ends of the core material raw material S3, which can effectively save manpower, improve work efficiency, promote the automated molding of the core material, and can further cooperate with other automated production equipment to form a composite board production line, greatly improving the production efficiency of composite boards.
