Description

Technical Field

[0001] This application belongs to the field of defect filling technology, and in particular relates to a defect filling device. Background Technology

[0002] Composite materials are used in many fields such as electronic products, aerospace components, medical equipment and building materials. For example, in the field of electronic components, composite materials are often made by combining a metal matrix with epoxy resin or silicone encapsulation materials.

[0003] Composite materials are materials made by combining two or more different materials through physical or chemical methods. The purpose is to combine the advantages of each component to achieve performance superior to that of a single material. Composite materials are usually composed of a matrix and a reinforcing phase. The matrix generally includes plastics, metals or ceramics, while the reinforcing phase includes fibers, particles or other forms of materials. The reinforcing phase is usually injected into the matrix as a casting material and then cured to synthesize the composite material.

[0004] However, because the casting process requires the application of asphalt varnish to the inner cavity of the matrix to isolate it from the casting material in order to improve production safety, and because there is a large difference in the coefficient of thermal expansion between the casting material and the matrix, and the casting material has a certain degree of elasticity, it will undergo plastic deformation during the curing process. Therefore, after the casting material is cured, the reinforcing phase formed will delaminate from the matrix, that is, the two will peel off, resulting in defects such as cavities, which will make the resulting composite material unable to meet the requirements for use.

[0054] Reference Appendix Figure 1 and Figure 2 This application provides a defect filling device for guiding potting liquid to fill a cavity defect between a matrix 500 and a reinforcing phase 600. The matrix 500 has openings at both ends, and the reinforcing phase 600 is located inside the matrix 500. The defect filling device includes a casting assembly 100, a sealing assembly 200, and an overflow assembly 300. The casting assembly 100 is internally connected to the matrix 500 and located at both ends of the matrix 500. The casting assembly 100 is used to connect the two ends of the cavity defect and guide potting liquid to fill the cavity defect. The sealing assembly 200 is located between the casting assembly 100 and the matrix 500 and is used to seal the connection between the matrix 500 and the casting assembly 100. The overflow assembly 300 is connected to the casting assembly 100 and is used to provide suction force to guide the potting liquid.

[0055] Reference Appendix Figures 1 to 3 In some embodiments, the casting assembly 100 includes a casting element 101 and a collecting element 102. The casting element 101 is disposed at one end of the substrate 500 and communicates with it. The casting element 101 is used to receive the potting liquid and guide it into the cavity defect. The collecting element 102 is disposed at the other end of the substrate 500 relative to the casting element 101 and communicates with it.

[0056] Specifically, the substrate 500 has openings at both ends. The reinforcing phase 600 formed after the casting material has cured is located inside the substrate 500. The casting member 101 and the collecting member 102 are respectively located at both ends of the substrate 500. The potting liquid is poured from the end where the casting member 101 is located until the potting liquid flows through the cavity defect between the substrate 500 and the reinforcing phase 600. The remaining potting liquid flowing out of the cavity defect is then collected by the collecting member 102. Based on the flow direction of the potting liquid under the action of gravity, the casting member 101 and the collecting member 102 are located at the top and bottom of the substrate 500, respectively. The casting member 101 is used to receive the potting liquid and guide it into the cavity defect. The collecting member 102 is used to collect the excess potting liquid that flows out after the cavity defect is filled, so as to facilitate the next use.

[0057] Reference Appendix Figures 5 to 8In some embodiments, the casting component 101 further includes a receiving portion 1011 and a guiding portion 1012. The two ends of the receiving portion 1011 are connected, one end of the receiving portion 1011 is open, and the other end is provided with a plurality of through holes. The guiding portion 1012 is fixed to one end of the receiving portion 1011. The guiding portion 1012 is connected to the receiving portion 1011 through the plurality of through holes, and the guiding portion 1012 is connected to the cavity defect.

[0058] Specifically, the receiving part 1011 is hollow inside and open at one end. The open end of the receiving part 1011 is used to receive potting liquid. The other end of the receiving part 1011 is provided with multiple through holes to guide the potting solution in the receiving part 1011 to the guiding part 1012, and also to reduce the impact of the potting liquid entering the receiving part 1011 so that the potting liquid flows slowly to the guiding part 1012.

[0059] Reference Appendix Figure 2 , Figure 3 , Figure 4 , Figure 6 as well as Figure 8 In some embodiments, the end of the guide portion 1012 that is relatively far from the receiving portion 1011 is covered on the reinforcing phase 600, and a first guide channel 400 is provided between the guide portion 1012 and the substrate 500. The first guide channel 400 is used to introduce the potting liquid from the guide portion 1012 into the cavity defect.

[0060] Specifically, the guide portion 1012 is fixed to the end of the receiving portion 1011 that is relatively close to the substrate 500. The guide portion 1012 is connected to the receiving portion 1011 through multiple through holes. The end of the guide portion 1012 that is relatively far away from the receiving portion 1011 is covered on the reinforcing phase 600. The end of the guide portion 1012 that is relatively far away from the receiving portion 1011 is clamped with the receiving portion 1011 to form a storage space. The storage space is used to temporarily store the potting liquid flowing in through the through holes. The end of the guide portion 1012 that is relatively far away from the receiving portion 1011 is used to isolate the temporarily stored potting liquid from the reinforcing phase 600.

[0061] The outer diameter of the end of the guide portion 1012 that is relatively far from the receiving portion 1011 is not greater than the inner diameter of the substrate 500, thereby forming a first guide channel 400 between the two. The potting liquid temporarily stored in the storage space is prevented from directly contacting the reinforcing phase 600 due to the end of the guide portion 1012 that is relatively far from the receiving portion 1011, and flows to the edge of the receiving portion 1011 to enter the first guide channel 400. The first guide channel 400 is used to guide the potting liquid temporarily stored in the storage space into the cavity defect between the substrate 500 and the reinforcing phase 600.

[0062] Reference Appendix Figure 3 and Figure 8In some embodiments, a truncated cone is provided at the center of the receiving part 1011. The cross-sectional area of ​​the truncated cone gradually increases from the end of the receiving part 1011 with an opening to the other end, and multiple through holes are evenly arranged around the truncated cone.

[0063] Specifically, the truncated cone is located at the center of the receiving part 1011. The cross-sectional area of ​​the truncated cone gradually increases from the end of the receiving part 1011 with an opening to the other end. That is, the tip of the cone protrudes towards the opening end of the receiving part 1011, thereby forming a structure in the receiving part 1011 that is high in the middle and low around the edges. The potting liquid flowing into the receiving part 1011 cannot stay at the center of the receiving part 1011. It flows to the periphery of the truncated cone under the influence of gravity. By evenly arranging multiple through holes around the truncated cone, all the potting liquid around the truncated cone flows into the guiding part 1012, thereby avoiding the retention of potting liquid.

[0064] Reference Appendix Figure 3 and Figure 9 In some embodiments, the collection component 102 further includes a connecting portion 1021 and a storage portion 1022. The connecting portion 1021 is disposed at one end of the base 500, and the storage portion 1022 is disposed on the connecting portion 1021. The storage portion 1022 is hollow inside and one end is connected to the cavity defect. The storage portion 1022 is used to store the potting liquid flowing out of the cavity defect.

[0065] Specifically, the connecting part 1021 is covered at one end of the base 500 and connected to the base 500. The storage part 1022 is located at the center of the connecting part 1021. The storage part 1022 is recessed in a direction away from the reinforcing phase 600 so that the interior of the storage part 1022 is hollow, forming a buffer space. The buffer space is used to store the potting liquid that overflows after filling the cavity defects through the first guide channel 400.

[0066] Reference Appendix Figures 1 to 3 In some embodiments, a first connecting member 700 is provided between the collecting member 102 and the overflow component 300. One end of the first connecting member 700 extends into the storage part 1022 to a predetermined depth to prevent the potting liquid in the storage part 1022 from flowing directly into the overflow component 300.

[0067] Specifically, the first connecting member 700 is hollow inside and is used to transport liquid or gas. The first connecting member 700 includes, but is not limited to, connecting nozzles, hoses, and hollow tubes. One end of the first connecting member 700 extends into the storage section 1022 to a predetermined depth. That is, the potting liquid stored in the buffer space exceeds a certain volume, so that it submerges one end of the first connecting member 700 before it can enter the overflow assembly 300 through the first connecting member 700. This is to ensure that the potting liquid completely fills the cavity defect before overflowing, and to prevent the potting liquid in the storage section 1022 from flowing directly into the overflow assembly 300, thereby affecting the operator's judgment and mistakenly believing that the potting liquid has filled the cavity defect.

[0068] Reference Appendix Figure 3 In some embodiments, the overflow assembly 300 includes an overflow member 301, a viewing window 302, and a vacuum pump 303. The overflow member 301 is hollow inside and open at one end. The overflow member 301 is connected to the casting assembly 100. The viewing window 302 is covered at the open end of the overflow member 301 and is used to observe the internal condition of the overflow member 301 from the outside. The output end of the vacuum pump 303 is connected to the overflow member 301.

[0069] Specifically, the overflow component 301 is open at one end and hollow inside. The viewing window 302 is covered at the open end of the overflow component 301. The viewing window 302 is made of transparent material so that the operator can observe the internal condition of the overflow component 301 from the outside. The vacuum pump 303 includes an input end and an output end. Its input end is electrically connected to a power source, and its output end is used to generate suction force.

[0070] The interior of the overflow component 301 is connected to the storage unit 1022 through the first connecting component 700. The interior of the overflow component 301 is also connected to the output end of the vacuum pump 303 through the second connecting component 800. The second connecting component 800 includes, but is not limited to, a nozzle, a hose, or a hollow tube.

[0071] In actual operation, by turning on the vacuum pump 303, the air in the overflow tank, buffer space, cavity defect, first guide channel 400 and storage space of the suction air path is sequentially extracted to make it into a vacuum state. The potting liquid in the receiving part 1011 will enter the storage space, first guide channel 400, cavity defect, buffer space and overflow tank in sequence through multiple through holes due to pressure. When the operator observes the potting liquid in the overflow tank, that is, the potting liquid in the buffer space has submerged the first connecting member 700, it is believed that the potting liquid has filled the first guide channel 400 and cavity defect. Therefore, the vacuum pump 303 can be turned off to stop the suction.

[0072] It should be noted that in actual operation, since the overflow component 300 provides suction to accelerate the flow of potting liquid through the cavity defect, air bubbles are inevitably generated during the process, so that the cavity defect is not completely filled. However, by setting a buffer space to temporarily store a certain amount of potting solution until it submerges the first connecting member 700 and enters the overflow component 300, it can be ensured that when the operator observes the potting liquid in the overflow tank and turns off the vacuum pump 303, a large amount of potting liquid flowing through the cavity defect has filled the gaps occupied by air bubbles, thereby improving the potting quality.

[0073] The preset depth refers to the length of the first connecting member 700 extending into the buffer space from the end of the collecting member 102 that is relatively far from the reinforcing phase 600. The longer the preset depth, the later the filling liquid is observed in the overflow tank, and vice versa. The operator should set the preset depth according to the number of voids and defects between the matrix 500 and the reinforcing phase 600 to ensure that the voids and defects are completely filled.

[0074] Reference Appendix Figure 1 , Figure 3 as well as Figure 10 In some embodiments, the sealing assembly 200 includes a connector 201 and at least three seals. The connector 201 is sleeved over the casting 101 and the base 500. The two ends of the connector 201 are respectively connected to the casting 101 and the base 500. Two seals are respectively disposed at the two ends of the connector 201, and another seal is disposed between the collecting member 102 and the base 500.

[0075] Specifically, the connector 201 is a connecting ring. The connector 201 is sleeved on the outside of the casting 101 and the base 500. The side wall of the connector 201 is fixedly connected to the casting 101. The outer wall of the connector 201 is also provided with a surrounding boss. The connector 201 abuts against the top of the base 500 through the surrounding boss.

[0076] The seals include, but are not limited to, rubber rings, O-rings, oil seals, gaskets, and sealant. The seals are used to increase the airtightness of the suction path of the vacuum pump 303 and prevent the generation of air bubbles. One seal is located between the connector 201 and the casting part 101, another seal is located between the connector 201 and the base 500, and the last seal is located between the collecting part 102 and the base 500.

[0077] Reference Appendix Figure 1 and Figure 3 In some embodiments, the sealing assembly 200 further includes at least one fastener 202 and at least two limiting members 203. One end of the fastener 202 is connected to the connector 201 and the other end is connected to the collecting member 102. The two limiting members 203 are disposed at both ends of the fastener 202 and are detachably connected to it.

[0078] Specifically, the fastener 202 is a stud with threads at both ends, and the limiting member 203 is a nut. One end of the fastener 202 passes through the surrounding boss on the outer wall of the connector 201, and the other end passes through the collecting member 102, and is threadedly connected to the two limiting members 203 respectively. Since the side wall of the connector 201 is also fixedly connected to the casting member 101, the casting assembly 100 and the base 500 are tightly connected as a whole.

[0079] It should be noted that, in order to ensure the airtightness of the suction air path of the vacuum pump 303, the number of fasteners 202 and limiting members 203 should be increased according to the actual situation, and each fastener 202 should be matched with two limiting members 203 for fastening.

[0080] This application provides a defect filling device. The casting assembly 100 and the overflow assembly 300 cooperate to guide the potting liquid through the cavity defect between the matrix 500 and the reinforcing phase 600, thereby filling the cavity defect to form a composite material for application, thus saving manufacturing costs. A sealing assembly 200 seals the casting assembly 100 and the matrix 500, ensuring that the potting liquid, guided by the overflow assembly 300, flows from the first guide channel 400 into the cavity defect and is collected by the collector 102. A truncated cone and a through-hole surrounding it reduce the impact of the potting liquid and guide it to the first guide channel 400. A guide portion 1012 prevents the potting liquid from directly contacting the reinforcing phase 600, and the first guide channel 400 on the guide portion 1012 introduces the potting liquid into the cavity defect. The overflow assembly 301, the viewing window 302, and the vacuum pump 303 cooperate to accelerate the potting liquid filling speed of the cavity defect and determine whether the cavity defect is filled.

[0081] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0082] The above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in this application.
