Description

Technical Field

[0001] This invention relates to the field of basalt fiber composite material preparation, and more particularly to a method for preparing basalt fibers mixed with rare earth elements for unmanned aerial vehicles. Background Technology

[0002] In the field of basalt fiber composite material preparation, existing methods for preparing basalt fibers mixed with rare earth elements for UAVs typically revolve around the mold operating surface, basalt fiber dry cloth or phenolic prepreg, a closed system, vacuuming, baking and curing, an adhesive layer, and a corresponding structural layer such as a polymethacrylimide foam board or UAV arm. This involves first preparing a basalt fiber reinforced board, then laying the product structure, closing the mold, and laminating and curing. However, this approach suffers from limitations such as unclear placement of the mixed rare earth elements, unclear processing links between the basalt fiber reinforced board and the adhesive layer, and direct entry into the second lamination and curing process after the first board formation. Existing methods often incorporate the mixed rare earth elements into the resin, board material, or other bulk materials, or directly superimpose subsequent interlayer materials during adhesive layer laying, lacking a continuous processing approach that addresses the adhesion state of the basalt fiber reinforced board, adhesive layer, and mixed rare earth elements.

[0003] Under the constraint of the stable state after basalt fiber reinforced board is baked in an oven, the bonding layer laying state and the mixed rare earth adhesion state are prone to disconnection, and the mixed rare earth adhesion surface does not correspond to the contact surface of the basalt fiber reinforced board, making it difficult to meet the requirement of achieving stable mixed rare earth bonding layer. Existing board preparation routes usually focus on the setting of release agent, lay-up, sealing system setting, vacuuming and baking curing, and then complete the product structure laying around the bonding layer and the corresponding structural layer of polymethyl methacrylate foam board or drone arm. However, after the first board is formed, there is a lack of gating link around the current state. Whether the board has reached a stable state, whether it has the conditions for bonding layer laying, and whether it has the conditions for mixed rare earth adhesion are often not continuously determined in the same link, resulting in a lack of consistent constraints between subsequent adhesion and lamination curing actions.

[0004] For the joint processing of basalt fiber reinforced boards, adhesive layers, mixed rare earth adhesion states, and mixed rare earth adhesive layers, existing technologies generally lack a processing chain that connects oven baking, stability determination, adhesive layer laying state determination, mixed rare earth adhesion state determination, and adhesion and adhesive layer configuration. This makes it difficult to form a consistent process from board formation, state determination, adhesion, product structure laying to mold operation surface preparation in application scenarios such as UAV arm corresponding structural layers or polymethacrylamide foam boards. As a result, the correspondence between mixed rare earth adhesion states and mixed rare earth adhesive layers is unclear, and the calling relationship of adhesion surface direction and interlayer position is unclear when laying product structures. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a method for preparing basalt fibers mixed with rare earth elements for unmanned aerial vehicles (UAVs), comprising:

[0006] S100. Obtain the mold operating surface, perform layering, release cloth laying, sealing system setting and baking curing treatment to obtain basalt fiber reinforced board;

[0007] The mold operating surface is the bearing surface for laying layers, laying release fabric, laying auxiliary materials and setting up the subsequent sealing system. The mold operating surface can come directly from the reusable state after the previous round of cutting and mold operating surface finishing, or it can come from the initial state after the current round of preparation is completed.

[0008] S200. Based on the basalt fiber reinforced board, perform oven baking treatment, stability determination treatment, and perform adhesive layer laying state determination and mixed rare earth adhesion state determination treatment to obtain the mixed rare earth adhesion state.

[0009] S300. Based on the mixed rare earth adhesion state, the solution slurry of the mixed rare earth and the adhesive layer is prepared, and then the mixed rare earth is attached to the side of the adhesive layer near the basalt fiber reinforced plate to obtain a second mixed rare earth attachment record, thereby completing the adhesive layer configuration and obtaining the mixed rare earth adhesive layer.

[0010] S400. Based on the mixed rare earth adhesive layer, the product structure is laid out, molded and laminated for curing, and then cut and mold operation surface is cleaned to obtain the mold operation surface cleanup record.

[0011] Furthermore, the processes of layup, release fabric installation, sealing system setup, and baking / curing include:

[0012] The layup process includes: inspecting the mold operating surface and setting the release agent, placing basalt fiber dry cloth or phenolic prepreg in a predetermined layup sequence, and simultaneously recording the layup direction, stacking position and edge bonding status of each layer of material.

[0013] The release fabric laying and sealing system setting process includes: laying the release fabric flat on top of the layup material, laying the guide net or breathable felt according to the type of layup material, setting the guide pipe, and then setting the sealing strip, vacuum bag film and connecting the air extraction pipe to perform vacuuming process.

[0014] The baking and curing process includes: after vacuuming to a stable state, introducing resin into the basalt fiber dry cloth scene, directly baking and curing the phenolic prepreg scene, removing the sealing system and taking off the board after curing to obtain the basalt fiber reinforced board.

[0015] Furthermore, the oven baking process includes:

[0016] The oven baking process includes: placing the basalt fiber reinforced board into the oven, keeping the board in an unfolded state at a predetermined position, simultaneously heating the surface and edges of the board, recording the time of entry and exit from the oven, the position of the board and the surface state, and generating a first current state record.

[0017] Furthermore, the process of determining a stable state includes:

[0018] The stable state determination process includes: based on the first current state record, checking the surface residue, edge lifting and flat laying states of the board, determining the state of continuous surface of the board, layable edges and consistent with the records of the same batch as a stable state, and generating a second current state record.

[0019] Furthermore, the process for determining the bonding layer laying status and the mixed rare earth adhesion status includes:

[0020] The process for determining the bonding layer laying status and the mixed rare earth adhesion status includes: matching the basalt fiber reinforced board with the candidate bonding layer based on the stable state result in the second current state record;

[0021] When epoxy film is used subsequently, the continuity of the board surface and the position of the film are determined accordingly; when epoxy resin filler mat or unsaturated polyester resin filler mat is used subsequently, the contact area between the board surface and the mat is determined accordingly, and the adhesive layer laying status is determined.

[0022] After the adhesive layer laying status is determined, the mixed rare earth adhesion status is determined:

[0023] Only when the basalt fiber reinforced board has reached a stable state and the corresponding adhesive layer is ready for laying, the board is recorded as having entered the mixed rare earth adhesion state.

[0024] When the basalt fiber reinforced board has not reached a stable state, the mixed rare earth attachment link is not opened, and the previous oven baking treatment record is sent back.

[0025] When the basalt fiber reinforced board has reached a stable state but the adhesive layer has not been laid, the board should not be passed on to the next step in this process.

[0026] The adhesive layer laying state and the mixed rare earth attachment open state of the corresponding plate are combined and recorded to obtain the mixed rare earth attachment state.

[0027] Furthermore, the process of preparing and processing the solution slurry includes:

[0028] The solution slurry preparation process includes: matching the mixed rare earth with the adhesive layer in the same batch; when the adhesive layer is an epoxy film, adding the mixed rare earth to a predetermined solution slurry and mixing continuously; when the adhesive layer is an epoxy resin filled surface felt or an unsaturated polyester resin filled surface felt, configuring the mixed rare earth and the corresponding resin state surface felt into an adhesive state, and generating a first mixed rare earth adhesion record.

[0029] Furthermore, the process of attaching the mixed rare earth elements to the adhesive layer on the side near the basalt fiber reinforced plate includes:

[0030] Based on the first mixed rare earth adhesion record, the adhesive layer is unfolded to the state to be adhered;

[0031] When the adhesive layer is an epoxy film, the prepared solution slurry is continuously spread along one side of the epoxy film, and the adhesion sequence of the edge area and the middle area is consistent.

[0032] When the adhesive layer is epoxy resin filled surface felt or unsaturated polyester resin filled surface felt, the mixed rare earth is continuously attached along the side of the surface felt adjacent to the basalt fiber reinforced plate, and the distribution of the mixed rare earth on the surface felt is checked segment by segment to check whether the edges and the middle are continuous.

[0033] The adhesion treatment does not penetrate into the interior of the basalt fiber reinforced board, the interior of the PMI foam board, or the interior of the corresponding structural layer of the drone arm; it only forms an adhesion surface on one side of the adhesive layer.

[0034] If edge defects, local discontinuities, or incorrect orientation of the adhesive surface are found during the adhesion process, the adhesive layer is returned to the adhesion station and the adhesion process is repeated according to the same part number.

[0035] For adhesive layers that are correctly oriented and continuously attached, record the attachment completion status, and record it together with the basalt fiber reinforced plate number, adhesive layer number, and mixed rare earth type to obtain the second mixed rare earth attachment record.

[0036] Furthermore, the process of configuring the adhesive layer includes:

[0037] Based on the second mixed rare earth adhesion record, the adhesive layer that has completed the adhesion treatment is shaped and sorted, the adhesion surface and the non-adhesion surface are distinguished, and the position is sorted according to the subsequent laying direction to form a mixed rare earth adhesive layer.

[0038] Furthermore, the process of product structure laying, mold closing, and lamination curing includes:

[0039] The product structure laying process includes: placing a lower basalt fiber reinforced plate on the mold operating surface, placing a mixed rare earth adhesive layer on top of the basalt fiber reinforced plate with the adhesive surface of the mixed rare earth adhesive layer facing the basalt fiber reinforced plate, then placing a PMI foam board or the corresponding structural layer of the drone arm, and then placing another layer of basalt fiber reinforced plate; the placement order, edge alignment status, and adhesive surface orientation status of each layer are recorded synchronously, and the process is stopped and re-placed when the orientation is reversed or misaligned;

[0040] The mold closing and lamination curing process includes: checking the placement order of each layer in the mold according to the first lamination curing record, performing mold closing, verifying the adjacent positions of the basalt fiber reinforced board and the mixed rare earth adhesive layer, entering lamination curing after the mold is closed, maintaining the continuous curing state of the same product structure, and generating a second lamination curing record.

[0041] Furthermore, the process of cutting and finishing the mold operating surfaces includes:

[0042] Based on the second lamination curing record, the edges of the laminated and cured board are trimmed. After trimming, the product is removed from the mold operating surface. The mold operating surface is cleaned of residues, the edge condition is checked, and the residual condition of the release agent is checked. After cleaning, the status is written to the sorting status for the next round of use, and the final product is obtained.

[0043] The key innovations of this invention include:

[0044] (1) A continuous processing chain consisting of oven baking, stability determination, adhesive layer laying state determination and mixed rare earth adhesion state determination is constructed around the basalt fiber reinforced board. The mixed rare earth adhesion state is generated after the first board formation and before the mixed rare earth adhesion, and the mixed rare earth introduction action is limited to the process chain constrained by the determination.

[0045] (2) A continuous processing chain consisting of solution slurry configuration, adhesion and adhesive layer configuration is constructed around the adhesive layer, the mixed rare earth is defined to be attached to the adhesive layer on the side close to the basalt fiber reinforced plate, and the mixed rare earth adhesive layer is formed by epoxy film, epoxy resin filled surface felt or unsaturated polyester resin filled surface felt.

[0046] (3) Construct a continuous processing link consisting of product structure laying, mold closing, lamination and curing, cutting and mold operation surface finishing around the basalt fiber reinforced board, the mixed rare earth adhesive layer and the corresponding structural layer of polymethyl methacrylate foam board or UAV arm, and send the mold operation surface finishing record back to the previous work station of mold operation surface finishing process to form a closed loop record link connected with the board forming process.

[0047] The following are its main beneficial effects:

[0048] (1) In view of the problem that the existing solution directly enters the second lamination and curing after the first board is formed and lacks the gate control link around the current state, the present invention generates the mixed rare earth adhesion state by oven baking of the basalt fiber reinforced board, stability determination, adhesive layer laying state determination and mixed rare earth adhesion state determination, so that the mixed rare earth adhesion is consistent with the previous board state, and the processing link between the basalt fiber reinforced board and the adhesive layer is fixed.

[0049] (2) In view of the problems of unclear mixed rare earth introduction position and mixed rare earth being incorporated into resin or board phase in the existing scheme, the present invention forms the mixed rare earth adhesive layer by the attachment treatment of the mixed rare earth on the side of the adhesive layer near the basalt fiber reinforced board, so that the attachment surface of the mixed rare earth, the contact surface of the basalt fiber reinforced board and the interlayer position in the subsequent product structure laying are consistent.

[0050] (3) In view of the problem that the adhesive layer in the existing solution is only used as an interlayer connection material and lacks a configuration link around the mixed rare earth, the present invention integrates epoxy film, epoxy resin filled surface felt or unsaturated polyester resin filled surface felt into the formation link of the mixed rare earth adhesive layer through solution slurry configuration, adhesion and adhesive layer configuration treatment. A continuous correspondence is established between the type of adhesive layer and the adhesion state of the mixed rare earth.

[0051] (4) In view of the problem that the calling relationship between board forming, bonding and product structure laying in the existing solution is unclear, the present invention establishes a unified product structure laying link around the basalt fiber reinforced board, the mixed rare earth adhesive layer and the corresponding structural layer of polymethyl methacrylate foam board or UAV arm, so that the adhesion surface direction, interlayer placement order and lamination curing object are called and recorded in the same process.

[0052] (5) In view of the problem that the mold operation surface lacks continuous connection between the cutting process and the next board forming process in the existing solution, the present invention generates the mold operation surface sorting record by sorting the mold operation surface and sends the mold operation surface sorting record back to the previous board forming station, so that a continuous record relationship is formed between the mold operation surface, the basalt fiber reinforced board production and the subsequent product structure processing. Attached Figure Description

[0053] Figure 1 This is a schematic flowchart illustrating a method for preparing basalt fiber mixed with rare earth elements for unmanned aerial vehicles (UAVs) according to an embodiment of this application. Detailed Implementation

[0054] Example 1: Refer to Figure 1This is a schematic flowchart of a method for preparing basalt fiber mixed with rare earth elements for unmanned aerial vehicles (UAVs) according to an embodiment of the present invention. The process may include at least steps S100-S400:

[0055] S100. Obtain the mold operating surface, perform layering, release cloth laying, sealing system setting and baking curing treatment to obtain basalt fiber reinforced board;

[0056] S200. Based on the basalt fiber reinforced board, perform oven baking treatment, stability determination treatment, and perform adhesive layer laying state determination and mixed rare earth adhesion state determination treatment to obtain the mixed rare earth adhesion state.

[0057] S300. Based on the mixed rare earth adhesion state, the solution slurry of the mixed rare earth and the adhesive layer is prepared, and then the mixed rare earth is attached to the side of the adhesive layer near the basalt fiber reinforced plate to obtain a second mixed rare earth attachment record, thereby completing the adhesive layer configuration and obtaining the mixed rare earth adhesive layer.

[0058] S400. Based on the mixed rare earth adhesive layer, the product structure is laid out, molded and laminated for curing, and then cut and mold operation surface is cleaned to obtain the mold operation surface cleanup record.

[0059] Step S100 includes at least steps S110-S130:

[0060] S110. Obtain the mold operating surface, basalt fiber dry cloth and phenolic prepreg, set the release agent and perform layup treatment to obtain the first layup record.

[0061] Specifically, the mold operating surface is the bearing surface for laying layers, laying release fabric, laying auxiliary materials, and setting up the subsequent sealing system. The mold operating surface can come directly from the reusable state after the previous round of cutting and mold operating surface finishing, or it can come from the initial state after the current round of preparation. The basalt fiber dry cloth is a lay-up material without resin, and the phenolic prepreg is a lay-up material with phenolic resin. In this step, one or a combination of the two is selected according to the product structure.

[0062] In actual operation, the mold operating surface is first inspected to remove residues. Then, a release agent is applied to the mold operating surface, spreading along the surface and covering the layup area, which corresponds to the shape of the subsequent basalt fiber reinforced board. Subsequently, the basalt fiber dry cloth or the phenolic prepreg is placed on the mold operating surface in a predetermined layup sequence, including the first layer position, subsequent stacking positions, and edge alignment positions. When using the basalt fiber dry cloth, the laid-up material is in a state awaiting resin introduction; when using the phenolic prepreg, the laid-up material is in a state awaiting vacuuming and baking for curing.

[0063] Furthermore, during the layup process, the laying direction, stacking position, and edge adhesion of each layer of material are recorded simultaneously. For positions where wrinkles, offsets, or localized lifting occur, the material is repositioned. After repositioning, the same layup process is recorded again.

[0064] After the above processing, the mold operating surface, the basalt fiber dry cloth, the phenolic prepreg, the release agent setting status and the layup sequence are organized into a first layup record. The first layup record is written into the current batch record as the output field name of this step, and is called as the input field name of S120 for subsequent release cloth laying, auxiliary material laying and guide pipe setting.

[0065] S120. Based on the first layup record, perform the layup of release fabric, the layup of auxiliary materials and the setting of guide pipes to obtain the second layup record;

[0066] Specifically, the first layup record provides the type of layup material and the location of the layup area in this round, the release cloth is the isolation material located above the layup, the auxiliary material is a flow guide net or a breathable felt, and the flow guide tube is a channel component associated with vacuuming and resin introduction in the subsequent sealing system.

[0067] At the beginning of this step, the type of layup material and the location of the layup area in the first layup record are read first. The release cloth is then laid flat on top of the layup material. The release cloth covers the layup area and extends to the edge. The release cloth and the layup material are kept flat and in good contact.

[0068] Further, auxiliary material laying is performed based on the material type in the first layup record. When the layup material corresponding to the first layup record is basalt fiber dry cloth, a flow guide net is laid on top of the release cloth, and the flow guide net is spread along the subsequent resin flow area. When the layup material corresponding to the first layup record is phenolic prepreg, a breathable felt is laid on top of the release cloth, and the breathable felt is spread along the subsequent vacuuming area. After the auxiliary material laying is completed, the flow guide pipe is set according to the length or width direction of the layup area. One end of the flow guide pipe corresponds to the layup area inside the mold, and the other end extends to the outside of the mold for use with the vacuum pipe when setting up the subsequent sealing system. In the scenario of using basalt fiber dry cloth, the flow guide pipe is also used for subsequent resin introduction. In the scenario of using phenolic prepreg, the flow guide pipe is mainly used to cooperate with the air path arrangement of the sealing system.

[0069] Understandably, in this step, the laying status of the release fabric, the type of auxiliary material, the position of the auxiliary material, the position of the guide tube, and the extension status of the guide tube are recorded simultaneously. If there are wrinkles in the release fabric, misalignment of the auxiliary material, or deviation of the guide tube from the edge of the layup area, the release fabric is re-laid. After processing, the records of the same batch are updated.

[0070] After the above processing, a second layup record is formed. The second layup record is input into S130 as the output field name of this step. It is used for subsequent closed system settings, vacuuming and baking curing processes, and provides the corresponding relationship of the source of the preceding board for the current state determination of S200 in subsequent cross-main step processing.

[0071] S130. Based on the second layup record, a closed system setup, vacuuming, and baking curing process are performed to obtain a basalt fiber reinforced board.

[0072] Specifically, the second layup record provides the completion status of the release fabric, auxiliary materials, and guide tubes, and the sealing system is set up accordingly. The sealing system includes sealing strips, air extraction pipes, and vacuum bag film. In specific implementations, the air extraction pipes can be a combination of No. 1 air extraction pipe and No. 2 air extraction pipe.

[0073] In actual operation, the sealing strips are first set around the operating surface of the mold, and then the vacuum bag film is laid on top of the sealing strips so that the layup material, the release cloth, the auxiliary materials and the guide tube are sealed inside the closed system; then the air extraction pipe is connected to the guide tube and connected to the vacuum pumping device to perform vacuuming.

[0074] Furthermore, during the vacuuming process, the bonding and evacuation status of the sealing system are continuously monitored, and this state is maintained once the vacuum level reaches a stable state. In scenarios using basalt fiber dry cloth, resin is introduced through the guide tube after the vacuum reaches a stable state, and the sealing system is then kept in a stable state. In scenarios using phenolic prepreg, resin introduction through the guide tube is not performed; instead, baking and curing proceed directly after the vacuum reaches a stable state. Subsequently, the entire sealing system is sent to the baking and curing station, and baking and curing are performed according to the layup material type corresponding to the second layup record. After the board is cured, the vacuum bag film, the evacuation tube, and the sealing strip are removed, and the board is removed from the mold operating surface to obtain the basalt fiber reinforced board.

[0075] The basalt fiber reinforced board is the output field name of this step. This output field name is directly called as the input field name of S210 for subsequent oven baking processing and generation of the first current state record. At the same time, the basalt fiber reinforced board is also the source of the board for subsequent product structure laying with polymethacrylimide (PMI) foam board or the corresponding structural layer of the drone arm, and continues to be associated with the mixed rare earth attachment in S310 and the product structure laying in S410.

[0076] Summary of the technical effects of this step: This step connects the mold operating surface, layup material, release cloth, auxiliary materials, guide pipe, sealing system, vacuuming, and baking curing into a single board-forming chain. The basalt fiber dry cloth and phenolic prepreg form a unified basalt fiber reinforced board output on the same mold operating surface. In this way, subsequent current state determination and mixed rare earth adhesion revolve around the same board, and the mixed rare earth introduction window maintains consistency with the source of the preceding board in the second lamination curing.

[0077] Step S200 includes at least steps S210-S230:

[0078] S210. Obtain the basalt fiber reinforced board, perform oven baking treatment, and obtain the first current state record.

[0079] Specifically, the basalt fiber reinforced board, derived from the output field name "basalt fiber reinforced board" of S130, refers to a board that has undergone closed system setup, vacuuming, and baking curing. This step involves oven baking of this board. The oven is a station for continuously heating and placing the basalt fiber reinforced board. The oven baking process involves placing the basalt fiber reinforced board inside the oven, maintaining its unfolded state in a predetermined position, and simultaneously heating and maintaining the surface and edges of the board.

[0080] During actual operation, the basalt fiber reinforced board is first checked upon arrival. The check includes the shape of the board, the integrity of the board edges, and the surface condition after the previous sealing system is removed. After the check is completed, the basalt fiber reinforced board is sent into the oven in a single board manner or in a batch side by side. The boards are kept spaced apart inside the oven so that each board is in a distinguishable position in the same baking cycle.

[0081] Furthermore, when the basalt fiber reinforced board is obtained by introducing resin and baking curing basalt fiber dry cloth, the oven baking treatment further cleans up the residual state on the surface and the edge state of the board; when the basalt fiber reinforced board is obtained by vacuuming and baking curing phenolic prepreg, the oven baking treatment maintains the same heat treatment state on the surface and inside of the board as in the same batch.

[0082] Understandably, the oven baking process described in this step is not a simple repetition of the previous baking and curing process, but rather an independent pretreatment of the basalt fiber reinforced board after the first board formation and before the second lamination. This pretreatment is directly related to the subsequent determination of the adhesive layer laying state and the mixed rare earth adhesion state. Specifically, the time of entering the oven, the time of leaving the oven, the location of the board, the surface state of the board, and the edge state of the board are recorded item by item, and the sorting result of the oven baking process for this batch is recorded as the first current state record. The first current state record is the output field name of this step, which is directly called by the "first current state record" in S220, and forms a connection with the "mixed rare earth adhesion state" in S310 during cross-main step transmission, because the subsequent mixed rare earth, adhesive layer, and adhesion relationship are all based on the oven pretreatment state formed in this step.

[0083] S220. Based on the first current state record, perform stable state determination processing to obtain the second current state record.

[0084] Specifically, the first current state record provides the surface state, edge state, placement state, and corresponding state of the basalt fiber reinforced board after oven baking. This step performs a stability determination process based on this record. The stability determination process is a preliminary determination of whether the basalt fiber reinforced board can proceed to the subsequent adhesive layer laying station and rare earth mixing attachment station. In this invention, the stability state includes the stable state after vacuuming, the stable state after oven baking, and the state that can proceed to adhesive layer laying. The stable state after vacuuming comes from the board forming process in S130, and the stable state after oven baking comes from the input of this step. Both are unified in this step as the basis for determining subsequent processes.

[0085] During actual operation, the board number, baking batch, and board position in the first current status record are read first. Then, the records of the same board before and after the oven are checked. The check includes whether there are obvious residues on the board surface, whether there are local lifting on the board edge, whether the board's flat position has changed, and whether the processing order of boards in the same batch is consistent. When the board position is disordered, the board edge condition is abnormal, or the record is missing, the board is kept at the current workstation and does not proceed to the next judgment action. The abnormal content is then added to the first current status record.

[0086] Furthermore, after completing the corresponding verification, a stability determination is performed on the basalt fiber reinforced board. The determination method is to compare the state after oven baking with the subsequent adhesive layer laying requirements item by item. When the board surface is in a continuous state, the board edge is in a layable state, and the records of the same batch are consistent, the board is determined to be in a stable state. When the board still has local abnormalities, the board is returned to the oven for baking or returned to the board sorting position, and the determination is repeated in the subsequent steps.

[0087] Understandably, the triggering condition in this step is that the first current state record has been generated and the basalt fiber reinforced plate has left the oven; the boundary constraint in this step is to only judge the same plate from S210 and not to mix records across batches.

[0088] After the above processing, the plate status that has completed the stable state determination, the abnormal record status, and the status that can enter the next station are organized into a second current state record. The second current state record is the output field name of this step and is directly called by "second current state record" in S230; at the same time, the second current state record is also the source of the preliminary state for the adhesion treatment of mixed rare earth on the side of the adhesive layer near the basalt fiber reinforced plate in the subsequent S300, because plates that have not reached a stable state will not enter the mixed rare earth adhesion link.

[0089] S230. Based on the second current state record, perform adhesive layer laying state determination and mixed rare earth adhesion state determination processing to obtain the mixed rare earth adhesion state.

[0090] Specifically, the second current state record has indicated whether the basalt fiber reinforced board has reached a stable state for subsequent work stations. Based on this, this step performs two types of continuous determinations: the first is the determination of the adhesive layer laying state, and the second is the determination of the mixed rare earth adhesion state.

[0091] In this invention, the adhesive layer refers to an epoxy film, an epoxy resin-filled surface felt, or an unsaturated polyester resin-filled surface felt. The adhesive layer laying state determination is a determination of whether the basalt fiber reinforced board and any of the above adhesive layers are in a state where the laying action can begin. The mixed rare earth adhesion state determination is a determination of the state required for the mixed rare earth to adhere to the adhesive layer on the side close to the basalt fiber reinforced board.

[0092] During actual operation, the stable state result in the second current state record is read first, and then the basalt fiber reinforced board is matched with the selected adhesive layer. When epoxy film is used later, the continuous state of the board surface and the position of the film are determined accordingly. When epoxy resin filler felt or unsaturated polyester resin filler felt is used later, the contact area between the board surface and the felt is determined accordingly.

[0093] Furthermore, after determining the adhesive layer laying status, a mixed rare earth adhesion status determination is performed. The mixed rare earth includes one or more of La, Ce, and Y, preferably La-Ce, and more preferably La-Ce-Y. The mixed rare earth adhesion status determination does not involve reselecting the mixed rare earth composition, but rather makes a station-based determination on whether the current plate allows the mixed rare earth to adhere to the adhesive layer on the side near the basalt fiber reinforced plate.

[0094] Specifically, when the basalt fiber reinforced board has reached a stable state and the corresponding adhesive layer has been laid, the board is recorded as entering the mixed rare earth adhesion state; when the basalt fiber reinforced board has reached a stable state but the adhesive layer laying state is not completed, the board is kept in this step and not passed on to the next step; when the basalt fiber reinforced board has not reached a stable state, the mixed rare earth adhesion link is not opened and the previous oven baking treatment record is sent back.

[0095] Understandably, the automated triggering relationship in this step is reflected in the following: once the second current state record is written to the layable state, the same batch of panels will be transferred to the adhesive layer layable state determination; when the determination continues to write to the attachable state, the same panel will be transferred to the mixed rare earth attachment state determination, and the whole process will run continuously around the same record number of the same panel.

[0096] After the above processing, the adhesive layer laying state and the mixed rare earth attachment open state corresponding to the board are merged and recorded as the mixed rare earth attachment state. The mixed rare earth attachment state is the output field name of this step, which is directly called by "mixed rare earth attachment state" in S310 for subsequent mixed rare earth, adhesive layer and solution slurry configuration processing; at the same time, the mixed rare earth attachment state also constrains the attachment processing position of S320 and the product structure laying sequence of S410 across the main steps, because only the board that has completed the state determination in this step enters the mixed rare earth adhesive layer formation and product structure laying link.

[0097] Summary of the technical effects of this step: This step continuously integrates the oven baking, stabilization determination, adhesive layer laying determination, and mixed rare earth adhesion determination after the first board formation into the same state chain. This ensures that the mixed rare earth introduction action is no longer synchronized with board forming, but is initiated separately according to the board state before the second lamination. Compared with the existing process where basalt fiber reinforced boards directly enter the bonding and lamination process, this step fixes the timing of mixed rare earth introduction after the stabilization state and the introduction position of mixed rare earth between the basalt fiber reinforced board and the adhesive layer.

[0098] Step S300 includes at least steps S310-S330:

[0099] S310. Obtain the mixed rare earth, the adhesive layer and the mixed rare earth adhesion state, perform solution slurry preparation processing, and obtain the first mixed rare earth adhesion record.

[0100] Specifically, the mixed rare earth elements are derived from previously determined mixed rare earth types, including one or more of La, Ce, and Y, preferably La-Ce, and further, La-Ce-Y; the adhesive layer is derived from the interlayer material to be laid in the product structure, and in this step, the adhesive layer is in a state of pending configuration, which corresponds to any one of the following states: epoxy film, epoxy resin-filled surface felt, or unsaturated polyester resin-filled surface felt; the mixed rare earth attachment state comes from the output field name "mixed rare earth attachment state" of S230, which indicates whether the basalt fiber reinforced board is allowed to enter the mixed rare earth attachment link and whether the adhesive layer has entered the laying state.

[0101] In actual operation, the mixed rare earth, the adhesive layer, and the mixed rare earth adhesion state are first matched within the same batch to avoid cross-contamination between different batches of basalt fiber reinforced boards and different batches of adhesive layers. After the matching is completed, the solution slurry is prepared according to the type of the adhesive layer. When the adhesive layer is an epoxy film, the board number and adhesive layer number in the mixed rare earth adhesion state are read first, and then the mixed rare earth is added to the predetermined solution slurry for continuous mixing to make the solution slurry spreadable. When the adhesive layer is an epoxy resin filled surface felt or an unsaturated polyester resin filled surface felt, the mixed rare earth and the surface felt of the corresponding resin state are configured to be adhered, and the position, surface continuity, and edge state of the surface felt before and after configuration are recorded simultaneously.

[0102] Furthermore, the solution slurry preparation process does not involve introducing the mixed rare earth into the entire closed system, nor into the entire polymethacrylimide (PMI) foam board, but rather involves localized preparation around the adhesive layer, which only serves the subsequent attachment action near the side of the basalt fiber reinforced board.

[0103] Understandably, the triggering condition in this step is that the mixed rare earth attachment state has been written into the attachable state; when the mixed rare earth attachment state is still in the closed state, this step remains in the pending state and no new attachment record is output; after the mixed rare earth attachment state is written into the attachable state, the solution slurry preparation process is then executed.

[0104] After the above processing, the mixed rare earth types, adhesive layer types, corresponding relationships within the same batch, and solution slurry configuration status are organized into a first mixed rare earth adhesion record. The first mixed rare earth adhesion record is used as the output field name of this step for the "first mixed rare earth adhesion record" in S320 to call, and continues to maintain a one-to-one correspondence with the first current status record of the preceding S210, the second current status record of S220, and the mixed rare earth adhesion status of S230.

[0105] S320. Based on the first mixed rare earth adhesion record, perform an adhesion treatment on the side of the adhesive layer near the basalt fiber reinforced plate to obtain a second mixed rare earth adhesion record.

[0106] Specifically, the first mixed rare earth adhesion record already indicates the configuration of the mixed rare earth and the adhesive layer. Based on this, this step determines the specific adhesion location of the mixed rare earth, which is defined as the side of the adhesive layer closest to the basalt fiber reinforced board. The side closest to the basalt fiber reinforced board refers to the side that will be directly adjacent to the basalt fiber reinforced board during subsequent product structure installation. This location is distinct from the other side, which will subsequently be adjacent to the corresponding structural layer of the PMI foam board or the drone arm.

[0107] During specific operation, the adhesive layer type and board number in the first mixed rare earth adhesion record are read first, and then the adhesive layer is unfolded to the adhesion state. When the adhesive layer is an epoxy film, the solution slurry prepared in S310 is continuously spread along one side of the epoxy film, and the adhesion sequence of the edge area and the middle area is kept consistent. When the adhesive layer is an epoxy resin filled surface felt or an unsaturated polyester resin filled surface felt, the mixed rare earth is continuously attached along the side of the surface felt adjacent to the basalt fiber reinforced board, and the distribution of the mixed rare earth on the surface felt is checked segment by segment.

[0108] Furthermore, the adhesion process in this step does not penetrate the interior of the basalt fiber reinforced board, the PMI foam board, or the corresponding structural layer of the UAV arm. Instead, it forms a distinct adhesion surface on one side of the adhesive layer. This adhesion surface corresponds to the subsequent contact surface of the basalt fiber reinforced board and remains separate from the subsequent laying surface on the other side.

[0109] Understandably, if edge defects, local discontinuities, or incorrect orientation of the adhesion surface are found during the adhesion process, the adhesive layer is redirected back to the adhesion station and the adhesion process is repeated according to the same plate number. For adhesive layers with correct orientation and continuous adhesion, the adhesion completion status is recorded. The adhesion completion status, along with the basalt fiber reinforced plate number, the adhesive layer number, and the mixed rare earth type, is recorded together to form a second mixed rare earth adhesion record.

[0110] The second mixed rare earth attachment record is used as the output field name of this step for S330 to call the "second mixed rare earth attachment record", and is referenced by S410 in the product structure laying process during cross-main step transmission, because S410 needs to determine the relative direction between the mixed rare earth attachment surface and the basalt fiber reinforced plate based on this record.

[0111] S330. Based on the second mixed rare earth adhesion record, perform epoxy film, epoxy resin filled surface felt or unsaturated polyester resin filled surface felt configuration treatment to obtain a mixed rare earth adhesive layer.

[0112] Specifically, the second mixed rare earth attachment record already specifies which type of adhesive layer the mixed rare earth is attached to and the orientation of the attachment surface. This step completes the final configuration of the adhesive layer based on this record. The configuration process does not involve reselecting the type of mixed rare earth, but rather shaping and organizing the adhesive layer that has already undergone the attachment process, ensuring that it maintains the correspondence between single layer, single side, and single plate when it enters the subsequent product structure laying station.

[0113] In actual operation, when the second mixed rare earth adhesion record corresponds to an epoxy film, the adhered and unadheded surfaces of the epoxy film are distinguished and recorded, and then the epoxy film is positioned according to the subsequent basalt fiber reinforced board laying direction; when the second mixed rare earth adhesion record corresponds to an epoxy resin filled surface felt, the edges, adhered surfaces, and unadheded surfaces of the surface felt are tidied up to ensure they correspond to the dimensions of the basalt fiber reinforced board; when the second mixed rare earth adhesion record corresponds to an unsaturated polyester resin filled surface felt, the edges and orientation of the surface felt are also tidied up so that the mixed rare earth adhesion surface directly faces the basalt fiber reinforced board during subsequent laying.

[0114] Furthermore, this step records the adhesive layer type, adhesion surface direction, board number, and laying status for each completed adhesive layer, thereby forming an interlayer material that can directly enter S410; this interlayer material is defined in this invention as a mixed rare earth adhesive layer.

[0115] Understandably, the mixed rare earth adhesive layer is the output field name of this step, and its output position is formed at the end of this main step and is directly called as "mixed rare earth adhesive layer" in S410; subsequently, after obtaining the basalt fiber reinforced board, the mixed rare earth adhesive layer and the corresponding structural layer of the PMI foam board or the drone arm, S410 will carry out the product structure laying.

[0116] Thus, the solution slurry preparation process in S310, the one-sided adhesion process in S320, and the adhesive layer preparation process in S330 form a continuous chain. S310 provides the pre-attachable record, S320 provides the adhesion surface position, and S330 provides the final layable mixed rare earth adhesive layer. The output of this main step continues to connect to the lamination and curing chain in S400.

[0117] Summary of the technical effects of this step: This step confines the configuration, adhesion, and bonding layer preparation of the mixed rare earth elements within the same interface window. The actual landing point of the mixed rare earth elements is fixed on the side of the bonding layer closest to the basalt fiber reinforced board, without penetrating the entire bulk material. Compared to the existing path where the basalt fiber reinforced board directly enters the lamination and curing process with the bonding layer, this step moves the mixed rare earth element introduction to the bonding layer configuration stage and records the adhesion direction and board number in the same record, making the input relationship for subsequent product structure laying clearer.

[0118] Step S400 includes at least steps S410-S430:

[0119] S410. Obtain the basalt fiber reinforced board, the mixed rare earth adhesive layer and the corresponding structural layer of PMI foam board or UAV arm, perform product structure laying treatment, and obtain the first lamination curing record.

[0120] Specifically, the basalt fiber reinforced board comes from the output field name "basalt fiber reinforced board" of S130, and the mixed rare earth adhesive layer comes from the output field name "mixed rare earth adhesive layer" of S330. Before entering this step, the board number and adhesion surface direction have already been matched. In this step, PMI stands for Polymethacrylimide, and the PMI foam board is the core material in the subsequent sandwich product structure. The corresponding structural layer for the UAV arm is the structural layer corresponding to the shape of the UAV arm, the position of the mounting base, the position of the first arm, and the position of the second arm.

[0121] During actual operation, the plate number of the basalt fiber reinforced plate and the adhesion direction of the mixed rare earth adhesive layer are read first. Then, the mold operation surface is used as the laying position for cleaning and verification. The verification content includes the edge status of the mold operation surface, the residual status of the release agent, and the status of the mold operation surface in the previous round of cleaning.

[0122] After verification, the installation is carried out according to the product structure. In the case of using PMI foam board, first place the lower basalt fiber reinforced board on the mold operating surface, then place the mixed rare earth adhesive layer on top of the basalt fiber reinforced board, with the adhesion surface of the mixed rare earth adhesive layer facing the basalt fiber reinforced board, then place the PMI foam board, and then place another layer of basalt fiber reinforced board. In the case of using the structure layer corresponding to the drone arm, first place the basalt fiber reinforced board corresponding to the drone arm, then place the mixed rare earth adhesive layer, with the adhesion surface of the mixed rare earth adhesive layer facing the basalt fiber reinforced board, and then place the structure layer corresponding to the drone arm.

[0123] Furthermore, during the laying process, the placement order, edge alignment, and orientation of each layer are recorded synchronously. When it is found that the mixed rare earth adhesive layer is reversed, the PMI foam board is misaligned, or the corresponding structural layer of the drone arm deviates from the product structure position, the current laying action is stopped, the previous step is returned to reposition, and the product structure laying process of the same board is continued.

[0124] Understandably, the triggering condition in this step is that the mixed rare earth adhesive layer has completed the configuration process of S330, and the basalt fiber reinforced board has completed the state determination link of S230. The boundary constraint in this step is that the same board number corresponds to only the same mixed rare earth adhesive layer number, and there is no layer change across batches. After the above processing, the product structure laying status of the basalt fiber reinforced board, the mixed rare earth adhesive layer, and the corresponding structural layer of the PMI foam board or UAV arm is written into the first lamination and curing record. The first lamination and curing record is the output field name of this step and is directly called by the "first lamination and curing record" in S420. At the same time, this record also maintains a corresponding relationship with the second mixed rare earth attachment record in the previous S320, which is used to identify the relative position of the attachment surface and the board during subsequent mold closing and lamination and curing.

[0125] S420. Based on the first lamination and curing record, perform mold closing and lamination and curing processes to obtain the second lamination and curing record.

[0126] Specifically, the first lamination and curing record already provides the product structure's laying sequence, adhesion surface direction, and interlayer correspondence. This step performs mold closing and lamination and curing processes based on this record. Mold closing refers to the action of bringing the mold into a closed state, and lamination and curing refers to the action of continuously curing the product structure after mold closing. The lamination and curing process includes the basalt fiber reinforced board, the mixed rare earth adhesive layer, and the PMI foam board or the corresponding structural layer of the drone arm. In actual operation, the placement order of each layer in the mold is first checked according to the first lamination and curing record, and then mold closing is performed to bring the mold into a closed state corresponding to the current product structure. After the mold is closed, the interlayer correspondence information in the first lamination and curing record is read again to verify the adjacent positions of the basalt fiber reinforced board and the mixed rare earth adhesive layer, and to verify the structure of the PMI foam board sandwich structure or the corresponding structural layer of the drone arm. After verification, lamination and curing are then performed.

[0127] Furthermore, during the lamination and curing process, the same product structure is kept in a continuous curing state, and the start time, end time, mold number, and panel number are written synchronously. If interlayer misalignment, exposed adhesive layer, or uneven product structure edges are found before lamination and curing, the mold closing state is released, and the product structure laying process in S410 is returned. When the product structure is in a state that can continue, the mold is kept closed and the current lamination and curing cycle is completed.

[0128] Understandably, the automation level in this step is reflected in the following: once the first lamination and curing record is written, mold closing and lamination and curing enter a continuous execution state. The same board will not return to the mixed rare earth attachment treatment station in this round of processing, but will only revert to the product structure laying treatment when interlayer misalignment is detected. After the above processing, the mold closing state, lamination and curing state, interlayer correspondence state and product structure completion state are recorded as the second lamination and curing record. The second lamination and curing record is the output field name of this step and is directly called by "second lamination and curing record" in S430. At the same time, the second lamination and curing record also provides a source for the subsequent cutting boundary and mold operation surface arrangement position, so that this main step and the mold operation surface of the next round S110 form a closed loop correspondence.

[0129] S430. Based on the second lamination and curing record, perform cutting and mold operation surface cleaning processing to obtain the mold operation surface cleaning record.

[0130] Specifically, the second lamination and curing record already provides the structural state of the product after lamination and curing. This step involves cutting based on this record, followed by mold operation surface preparation. The cutting refers to the action of removing and tidying the edges of the laminated and cured board. The mold operation surface preparation refers to the action of cleaning, verifying, and writing the status of the mold operation surface after cutting.

[0131] In actual operation, cutting is first performed based on the board number and product structure boundary in the second lamination and curing record. In the scenario of using a PMI foam board sandwich structure, the corresponding edges of the upper basalt fiber reinforced board, the mixed rare earth adhesive layer, and the outer edges of the PMI foam board and the lower basalt fiber reinforced board are cut together to bring the cut product edges into a unified boundary state. In the scenario of using the corresponding structural layer of the drone arm, the combined boundary of the basalt fiber reinforced board and the corresponding structural layer of the drone arm is cut, and the boundary is tidied up in the corresponding areas of the mounting base position, the first arm position, and the second arm position. After cutting, the product is removed from the mold operating surface, and the mold operating surface is then tidied up. The tidied up includes removing residues, checking the edge condition, checking the release agent residue condition, and checking the reusability of the mold operating surface after this round of mold closing.

[0132] Furthermore, during the mold operation surface preparation process, the positions of the previous closed system, the previous product structure laying positions, and the residual positions after this round of cutting are cleaned one by one, and the cleaned mold operation surface is written to the preparation status. If there are still residues or abnormal edge conditions on the mold operation surface, the preparation process continues until the mold operation surface enters a reusable state, and then the final preparation record is written. Understandably, the mold operation surface preparation record is the output field name of this step. Once the mold operation surface preparation record is written, it is called as the source of "mold operation surface" in the next round S110, so that the product structure laying process in S410, the mold closing and lamination curing process in S420, the cutting and mold operation surface preparation process in S430 and the mold operation surface acquisition in the previous S110 form a seamless connection.

[0133] Summary of the technical effects of this step: This step fixes the product structure laying, mold closing, and lamination curing involving the mixed rare earth adhesive layer within the same interlayer chain. Subsequent cutting and mold operation surface preparation continue to revolve around the same part number. Compared to the existing path of directly laminating sandwich structures or machine arm structures and ending the process, this step writes the adhesion direction of the mixed rare earth adhesive layer, the product structure laying sequence, and the source of the next round of mold operation surfaces into a continuous record, making the calling relationship between the preceding and following steps clearer.
