Technical Field

[0001] This disclosure relates to the field of protective material filling technology, and in particular to a protective material filling system and method. Background Technology

[0002] When laser drilling is performed on hollow components, the internal cavities of the hollow components need to be filled with protective material to prevent damage to the opposing wall surface caused by laser penetration during laser drilling (referred to as wall damage). Once wall damage occurs, it will directly lead to the scrapping of the workpiece.

[0003] Therefore, when laser drilling holes in hollow components, filling the internal cavities is particularly crucial. Summary of the Invention

[0004] This disclosure provides a protective material filling system and method; by employing negative pressure vibration to ensure that there are no air bubbles in the filling material before filling, the wall damage caused by air bubbles during subsequent laser drilling is avoided.

[0005] The technical solution disclosed herein is implemented as follows:

[0006] In a first aspect, this disclosure provides a protective material filling system, comprising: a slurry container, a vibration module, a vacuum pump, a crimping connector, a clamp, and a control module; the vacuum pump is connected to the slurry container, the outlet of the slurry container is connected to the inlet of the crimping connector, and the outlet of the crimping connector is connected to the internal cavity of the hollow component to be filled; the slurry container is used to carry the slurry to be filled into the hollow component; the control module is used to control the vibration module and the vacuum pump according to a received negative pressure vibration command; the vacuum pump is used to extract air from the slurry container based on the control of the control module; the vibration module is used to start vibration to expel air from the slurry in the slurry container based on the control of the control module; the clamp is used to fix the hollow component to be filled on the filling station; and the crimping connector is used to fill the internal cavity of the hollow component to be filled, which is connected to the outlet of the crimping connector, with the slurry flowing from the outlet of the slurry container to the inlet of the crimping connector.

[0007] Secondly, this disclosure provides a method for filling a protective material, the method comprising: receiving a negative pressure vibration command input by a user; controlling a vibration module to vibrate to expel air from a slurry container according to the negative pressure vibration command; and controlling a vacuum pump to extract air from the slurry container to obtain a bubble-free slurry for filling the internal cavity of a hollow component to be filled, which is connected to the outlet of a pressure connector.

[0008] Thirdly, this disclosure provides a control module including a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, implement the steps of the protective material filling method as described in the second aspect.

[0010] Fifthly, this disclosure provides a computer program product, wherein the computer program product includes a computer program or instructions, which, when run on a processor, cause the processor to execute the computer program or instructions to implement the steps of the protective material filling method as described in the second aspect.

[0011] In a sixth aspect, this disclosure provides a chip including a processor and a communication interface coupled to the processor, the processor being used to run programs or instructions to implement the protective material filling method as described in the second aspect.

[0012] This disclosure provides a protective material filling system, comprising: a slurry container, a vibration module, a vacuum pump, a crimping connector, a clamp, and a control module. The vacuum pump is connected to the slurry container, the outlet of the slurry container is connected to the inlet of the crimping connector, and the outlet of the crimping connector is aligned with the internal cavity of the hollow component to be filled. The slurry container is used to hold the slurry to be filled into the hollow component. The control module is used to control the vibration module and the vacuum pump according to a received negative pressure vibration command. The vacuum pump is used to extract air from the slurry container based on the control of the control module. The vibration module is used to activate vibration to expel air from the slurry in the slurry container based on the control of the control module. The clamp is used to fix the hollow component to be filled at the filling station. The crimping connector is used to fill the internal cavity of the hollow component to be filled, where the slurry flowing from the outlet of the slurry container to the inlet of the crimping connector is aligned with the outlet of the crimping connector. In this disclosure, before filling the component to be filled, the light-blocking particles and adhesive are mixed evenly, and the gas in the slurry is expelled by negative pressure vibration, thereby ensuring that the slurry entering the internal cavity of the component to be filled is free of air bubbles, thus avoiding wall damage caused by the presence of air bubbles. Furthermore, the slurry is injected into the internal cavity through the outlet of the crimp fitting that mates with the internal cavity, without affecting other internal cavities; that is, the filling of each internal cavity is independent. Compared with traditional filling methods, this avoids misfilling and also improves filling efficiency. Attached Figure Description

[0021] The technical solutions in the embodiments of this disclosure will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure are within the scope of protection of this disclosure.

[0022] Typical protective materials consist of light-blocking particles and an adhesive. The light-blocking particles are usually injected manually into the internal cavities of the hollow component to be filled, and then the adhesive is injected and mixed with the particles. However, as the structures of the hollow components to be filled become more complex, the internal cavities are mostly complex double-walled structures. For example, common turbine blades often have double-walled internal cavities to improve cooling efficiency.

[0023] For cavities with small spaces, extremely fine light-blocking particles are required for filling. However, after filling with fine light-blocking particles, it is difficult to inject adhesive into the cavity or mix it evenly with the light-blocking particles. If no adhesive is added, the light-blocking particles are too small and easily leak out of the cavity, resulting in a cavity and increasing the risk of wall damage during laser processing.

[0024] Therefore, this disclosure aims to provide a protective material filling system suitable for hollow components with complex internal cavities. Figure 1This disclosure presents a protective material filling system. For example... Figure 1 As shown, the protective material filling system includes: a slurry container 10, a vibration module 20, a vacuum pump 30, a crimping joint 40, a clamp 50, and a control module 60. The vacuum pump 30 is connected to the slurry container 10, the outlet of the slurry container 10 is connected to the inlet of the crimping joint 40, and the outlet of the crimping joint 40 is connected to the internal cavity of the hollow component to be filled.

[0025] The slurry container 10 is used to hold the slurry to be filled into the hollow component. Specifically, light-blocking particles and binder are mixed evenly (e.g., by ball milling the mixed light-blocking particles and binder) to obtain the slurry for filling into the hollow component, and the slurry is filled into the slurry container 10. The specific shape of the slurry container 10 is not limited in this disclosure, and may be, for example, […]. Figure 1 The cylindrical shape shown in the figure. In order to facilitate observation of the height of the slurry in the slurry container 10 when adding slurry, and to observe the density of the slurry during vibration, the slurry container 10 may be made of a transparent material.

[0026] After the slurry is added, the slurry container 10 needs a sealed space so that a negative pressure can be formed in the slurry container 10 by the vacuum pump 30. However, in order to make it easy to add slurry to the slurry container 10, the slurry container 10 includes a cover plate with a sealing element. After the slurry container 10 is filled, the slurry container is sealed by the cover plate.

[0027] The slurry container 10 is equipped with a vent valve for connecting the conduit of the vacuum pump 30. To prevent the vacuum pump 30 from accidentally drawing slurry from the slurry container 10 during operation, the vent valve can be positioned above the threshold line of the slurry container 10 (used to limit the amount of slurry added, ensuring it does not exceed this threshold line). In some feasible implementations, such as... Figure 1 The vent valve port is shown to be located on the cover plate.

[0028] In order to allow the slurry to flow smoothly from the outlet of the slurry container 10, the outlet of the slurry container 10 is located at the bottom and is connected to the inlet of the crimping connector 40 through a conduit, so that the slurry in the slurry container 10 reaches the inlet of the crimping connector 40 along the conduit.

[0029] The control module 60 may include a user interface. The operator can input a negative pressure vibration command through the user interface, and the control module 60 controls the vibration module 20 to vibrate and controls the vacuum pump 30 to work according to the negative pressure vibration command.

[0030] The vibration module 20 is used to expel air from the slurry in the slurry container 10 through vibration. The vibration module 20 consists of a fixed component and a vibration motor. The fixed component is used to fix the slurry container 10, and the vibration motor is used to provide the vibration source. Figure 1 The fixing component shown is a working plate. In one case, the middle of the working plate is flat, and the slurry container 10 is fixed on this flat surface. In another case, the middle of the working plate is hollow, and the lower half of the slurry container 10 passes through the hollow part of the working plate and is clamped and fixed on the working plate. In yet another case, the fixing component is an openable clamping device. When the clamping device is opened, the slurry container 10 is inserted. When closed, the side of the slurry container 10 is in close contact with the clamping device, fixing the slurry container 10 at a certain height above the ground.

[0031] Vacuum pump 30 is used to extract air from the slurry container 10, creating a negative pressure in the sealed space of the slurry container 10. While the vibration module 20 is discharging air from the slurry through vibration, vacuum pump 30 operates to extract air from the slurry container 10, which helps to remove gas from the slurry.

[0032] The crimp connector 40 is used to fill the internal cavity that connects to the outlet of the crimp connector 40 with the slurry flowing in from the inlet of the crimp connector 40. That is, each outlet of the crimp connector 40 connects to an internal cavity, so that the filling of each internal cavity does not affect each other.

[0033] For hollow components that need to be filled with multiple cavities, in some embodiments, such as Figure 2 As shown, the protective material filling system also includes: a multi-port valve 70 and a control module 60. The multi-port valve 70 is connected between the slurry container 10 and the crimping connector 40. Each passage in the multi-port valve 70 corresponds to an inlet of the crimping connector 40. The crimping connector 40 includes multiple inlets and outlets, with each inlet corresponding to one outlet. Each outlet corresponds to an internal cavity of the hollow component to be filled. Figure 2 The crimp fitting 40 shown includes three feed ports.

[0034] The control module 60 is used to control the opening of the selected passage in the multi-way valve 70 and to control the amount of slurry flowing into the selected passage. The operator sets the passage to be opened via a user interface, allowing the slurry to reach the inlet of the corresponding pressure connector 40 through the opened passage, and then enter the internal cavity that connects to the outlet of the pressure connector 40. Compared to the previous method of sealing other internal cavities to prevent interference during the filling of one internal cavity, which is time-consuming, labor-intensive, and inefficient, in this disclosure, each internal cavity corresponds to the outlet of the corresponding pressure connector 40, and the filling of each internal cavity does not affect the others, allowing for synchronous filling and improving filling efficiency.

[0035] The clamp 50 is used to fix the hollow part to be filled at the filling station. During the process of filling the hollow part with slurry, in order to ensure the uniform distribution of the filling material and the reliability of repeated positioning, and to ensure the consistency of each filling, the clamp 50 is needed to stabilize the hollow part to be filled at the filling station.

[0036] In this embodiment, before filling the component to be filled, the light-blocking particles and adhesive are mixed evenly, and the gas in the slurry is expelled by negative pressure vibration, thereby ensuring that there are no air bubbles in the slurry entering the internal cavity of the component to be filled, thus avoiding wall damage caused by the presence of air bubbles. Furthermore, injecting the slurry into the internal cavity through the outlet of the crimp fitting that connects to the internal cavity does not affect other internal cavities; that is, the filling of each internal cavity is independent. Compared with traditional filling methods, this avoids misfilling and also improves filling efficiency.

[0037] In some embodiments, such as Figure 3 As shown, the protective material filling system also includes: a receiving container 80, a clamp 50 and a crimping joint 40 that are sealed together, and the receiving container 80 and the clamp 50 are sealed together.

[0038] A receiving container 80, located below the clamp 50, is used to collect slurry that falls during the filling process. A vacuum pump 30 is also used to create negative pressure within the sealed space formed by the crimp connector 40, clamp 50, and receiving container 80. In some feasible embodiments, to ensure the sealed space is formed by the crimp connector 40, clamp 50, and receiving container 80, seals can be provided at the joints between the crimp connector 40 and clamp 50, and between the clamp 50 and receiving container 80. Two seals can be provided between the crimp connector 40 and clamp 50: a sealing ring and a sealing gasket. The sealing gasket has through holes that align with the outlet of the crimp connector 40, each through hole corresponding to an internal cavity to further increase airtightness.

[0039] The vacuum pump 30 extracts air from the sealed space formed by the pressure connector 40, clamp 50 and receiving container 80, making it a vacuum space. The internal cavity is also in a vacuum state. This helps to prevent the influence of air during the slurry filling process, and thus prevents the introduction of air gaps during the filling process (which may cause wall damage during subsequent laser drilling), ensuring that the filling quality is qualified.

[0040] In some embodiments, the receiving container 80 can be divided into two detachable parts: an upper part 801 equipped with a vent valve for connecting to the air pipe of the vacuum pump 30, and a lower part 802 for holding the material. The two parts are connected by a seal. Thus, when the spilled slurry accumulates to a certain amount and needs to be poured out, only the lower part 802 needs to be disassembled, without removing the entire connection of the receiving container 80, simplifying the operation in the production process.

[0041] In some embodiments, such as Figure 4 As shown, the protective material filling system also includes an anti-backflow module 90, which is connected between the receiving container 80 and the vacuum pump 30.

[0042] An anti-backflow device 90 is used to deposit any backflowed slurry to the bottom. Since the receiving container 80 is located below the clamp 50, slurry falling from above during the filling process may be sucked back by the vacuum pump 30, which could cause the vacuum pump 30 to malfunction or even be damaged. Therefore, an anti-backflow device 90 is installed between the vacuum pump 30 and the receiving container 80. If any backflowed slurry is present, it will deposit at the bottom of the anti-backflow device 90, without affecting the operation of the vacuum pump 30.

[0043] In some embodiments, such as Figure 5 As shown, the protective material filling system also includes a first sliding module 41 connected to the crimp connector 40. The arrow in the figure points to the front view of the first sliding module 41.

[0044] The control module 60 is also used to control the first sliding module 41 according to the received sealing command. The first sliding module 41 is used to drive the pressure connector 40 closer to the clamp 50 according to the control of the control module 60, until the clamp 50 and the pressure connector 40 are sealed together. The clamp 50 and the receiving container 80 are already sealed together. When slurry filling is required, the clamp 50 and the pressure connector 40 need to be sealed first. The operator operates on the user interface and inputs the sealing command to start the sealing. After receiving the sealing command, the controller 70 controls the first sliding module 41 to start sliding closer to the clamp 50 until the first sliding module 41 can no longer move, thus confirming that the clamp 50 and the pressure connector 40 are sealed together.

[0045] In some embodiments, the protective material filling system further includes a second sliding module connected to the receiving container 80.

[0046] The control module 60 is also used to control the second sliding module according to the received sealing command. The second sliding module is used to drive the receiving container 80 closer to the clamp 50 according to the control of the control module 60, until the clamp 50 and the receiving container 80 are sealed together. The clamp 50 and the pressure joint 40 are already sealed together. When slurry filling is required, the clamp 50 and the receiving container 80 need to be sealed first. The operator operates on the user interface and inputs the sealing command to start the sealing. After receiving the sealing command, the controller 70 controls the second sliding module to start sliding closer to the clamp 50 until the second sliding module can no longer move, thus confirming that the clamp 50 and the receiving container 80 are sealed together.

[0047] It should be noted that the first sliding module 41 and the second sliding module mentioned above can be any component capable of moving the pressure joint 40 and the receiving container 80, such as a servo motor or a cylinder. If it is a servo motor, a seal is achieved when the torque reaches a preset torque; if it is a cylinder, a seal is achieved by preventing the receiving container 80 from moving upward after contacting the clamp 50. This disclosure does not specifically limit the specific form of the first sliding module 41 and the second sliding module. In addition, in the protective material filling system, only one of the first sliding module 41 and the second sliding module can be provided, or both can be provided simultaneously. The purpose is to achieve a seal between the clamp 50, the pressure joint 40, and the receiving container 80 without manual operation, through the control module 60.

[0048] In some embodiments, such as Figure 6 As shown, the protective material filling system also includes a grouting module 100, which includes a driver 101, a grouting rod 102, and a piston 103. The piston 103 is connected to the bottom end of the grouting rod 102. The piston 103, indicated by the arrow in the figure, is installed at the position indicated by the dashed box below the grouting rod 102.

[0049] The control module 60 is also used to control the driver 101; the grouting module 100, under the control of the control module 60, drives the grouting rod 102 to move the piston 103 to squeeze the grout in the grout container 10 into the pressure joint 40. The outlet of the grout container 10 is located at the bottom, and the grout flows out to the pressure joint 40 by gravity. However, this gravity-based flow is relatively slow. Therefore, by squeezing the grout with the piston 103, the grout can be promoted to enter the pressure joint 40 quickly, thereby improving the filling efficiency.

[0050] In some embodiments, the piston 103 is sized to match the slurry container 10, and the piston 103 can be removed from the grouting rod 102, so that a matching piston 103 can be used depending on the slurry container 10 used.

[0051] Furthermore, in order to better control the grouting volume and grouting speed, in some embodiments, the driver 101 is a servo motor; the operator sets the grouting volume and grouting speed in the user graphical interface of the control module 60, and the control module 60 is specifically used to determine the control signal of the servo motor according to the set grouting speed and filling volume; the servo motor controls the moving speed and moving distance of the grouting rod 102 according to the control signal, and the grouting rod 102 drives the piston 103 to move to squeeze and make the grout in the grout container 10 flow into the pressure joint 40.

[0052] The moving speed of the grouting rod 102 is linearly related to the grouting speed. The grouting volume can also be determined based on the moving distance of the grouting rod 102 and the size of the grout container 10. Therefore, by changing the moving speed and moving distance of the grouting rod 102, the grouting speed and grouting volume can be changed accordingly.

[0053] Furthermore, if it is necessary to inject different amounts of grout into multiple internal cavities simultaneously, and to grout at different grouting speeds, a corresponding flow rate and volume control module is set at each outlet of the pressure connector 40. The control module 60 sets a corresponding grouting speed and grouting amount for each internal cavity. The control module 60 sends the corresponding grouting speed and grouting amount to the flow rate and volume control module. When the grout arrives, each outlet is controlled to grout according to the corresponding grouting speed and grouting amount.

[0054] In this embodiment of the disclosure, in order to ensure the filling quality, the grouting volume and grouting speed of different internal cavities may be different. Each internal cavity is filled precisely according to the requirements, and the filling process is fully automated. This automated control can reduce human error and improve the efficiency and quality of construction.

[0055] Furthermore, to facilitate observation of whether air bubbles exist in the slurry entering the crimping connector 40, the conduit between the slurry container 10 and the crimping connector 40 can be made transparent. In some embodiments, the protective material filling system further includes a micropump and an image acquisition unit. The micropump is disposed on the conduit between the slurry container 10 and the crimping connector 40, and is located close to the crimping connector 40. The image acquisition unit is used to acquire images of the conduit between the slurry container 10 and the crimping connector 40; the image acquisition unit transmits the acquired images to the control module 60, the control module 60 analyzes the images to determine whether there are air bubbles in the images, and if air bubbles are detected in the images, controls the micropump to operate, backflowing the slurry in the conduit back into the slurry container, and controls the vibration module 20 to vibrate for a preset time before restarting the slurry delivery.

[0056] The following is a complete filling process, including the following steps:

[0057] First, the mixed light-blocking particles and adhesive are ball-milled in a ball mill, and the resulting slurry is filled into slurry container 10.

[0058] Second, fix the slurry container 10 on the vibration module 20, cover it with a cover plate, and connect the air pipe of the vacuum pump 30 to the air vent of the slurry container 10.

[0059] Third, on the graphical user interface of the control module 60, the command to start negative pressure vibration is input, the control module 60 controls the vibration module 20 to start vibration, and controls the vacuum pump 30 to start to extract the air in the slurry container 10. The negative pressure vibration will stop automatically after a preset time, or according to the command to stop negative pressure vibration input by the operator on the graphical user interface, the vibration module 20 and the vacuum pump 30 will stop working.

[0060] Fourth, place the hollow part to be filled into the fixture 50, add seal 1 and seal 2, then place the fixture 50 at the corresponding filling station, and add seal 3 to the receiving container 80.

[0061] Fifth, a sealing command is input on the graphical user interface, and the control module 60 controls the first sliding module 41 and / or the second sliding module to move until a sealed connection is formed between the pressure joint 40, the clamp 50 and the receiving container 80.

[0062] Sixth, input the grouting preparation command on the graphical user interface and set the filling process of the hollow component to be filled (such as the filling sequence of the internal cavity, grouting speed, grouting volume, etc.). Then, the control module 60 controls the vacuum pump 30 to start extracting air from the sealed space formed by the pressure joint 40, the clamp 50 and the receiving container 80. When the air pressure reaches the preset value, the control module 60 controls the selected passage of the multi-way valve 70 to open, and controls the servo motor to work and the image acquisition module to start working. The servo motor drives the grouting rod 102 to move the piston 103, and transmits the grout through the conduit to the pressure joint 40, and then fills the internal cavity of the hollow component to be filled. The image acquisition module acquires images at a certain frequency and transmits the images to the control module 60. When the control module 60 detects air bubbles in the image, it controls the servo motor to stop working, controls the micro pump to work to return the grout in the conduit to the grout container 10, and controls the vibration module 20 to work. After the vibration is preset for a time, the grouting work continues until the grouting is completed.

[0063] Seventh: Remove the hollow component after grouting and place it in the oven. Gradually increase the temperature to cure the filling material, and the filling is complete.

[0064] Based on the same concept as the aforementioned protective material filling system, such as Figure 7 As shown, this disclosure also provides a method for filling protective material, applied to the control module 60 described above, the method including the following steps S701 and S702.

[0065] In step S701, a negative pressure vibration command input by the user is received.

[0066] In step S702, according to the negative pressure vibration command, the vibration module is controlled to vibrate to expel the air in the slurry container, and the vacuum pump is controlled to extract the air in the slurry container to obtain bubble-free slurry for filling the internal cavity of the hollow component to be filled into the outlet of the press fitting.

[0067] In some embodiments, the protective material filling method further includes: according to the received selected channel instruction, controlling the selected channel in the multi-way valve to open, so that the slurry is injected from the selected channel into the feed port corresponding to the crimping joint, and then fills the internal cavity that is connected to the discharge port corresponding to the feed port.

[0068] In some embodiments, the protective material filling method further includes: according to the received grouting preparation instruction, controlling a vacuum pump to extract air from the sealed space formed by the pressure connector, clamp and receiving container until the air pressure reaches a preset value; according to the received selected passage, controlling the selected passage in the multi-way valve to open, so that the grout is injected from the selected passage into the feed port corresponding to the pressure connector, and then fills the internal cavity that is connected to the discharge port corresponding to the feed port.

[0069] In some embodiments, the protective material filling method further includes: controlling the servo motor in the grouting module to work according to the received grouting preparation instruction, so as to drive the grouting rod to squeeze the grout in the grouting container through the piston.

[0070] In some embodiments, the grouting preparation command includes the grouting speed and grouting volume of each internal cavity. The above-mentioned control of the servo motor in the grouting module to work according to the received grouting preparation command to drive the grouting rod to squeeze the grout in the grouting container through the piston includes: controlling the moving speed and moving distance of the servo motor in the grouting module according to the received grouting preparation command to drive the grouting rod to squeeze the grout in the grouting container through the piston.
