Description

Technical Field

[0001] This application relates to the field of repair technology, specifically to a repair device. Background Technology

[0002] To improve performance, workpieces typically have a film layer formed on the surface of their substrate. However, because the film layer is harder than the substrate, when the substrate deforms due to external forces, the film layer can break and crack. These cracks expose the substrate beneath the film layer, failing to improve performance in that area and negatively impacting the overall appearance of the workpiece. To address this issue, repair devices can be used to repair the film layer cracks by applying filler to the crack location. However, current repair devices only apply filler to the surface of the crack and cannot fully penetrate into the crack's fissure. After wiping away excess filler from the film layer surface, some cracks remain, and the underlying substrate re-exposes, resulting in ineffective crack repair. Utility Model Content

[0003] In order to overcome the problem of poor repair effect of the repair device when repairing film cracks on the substrate, the present application provides a repair device.

[0004] The repair apparatus provided in this application includes a base, a loading assembly, a heating assembly, and a packing assembly. The loading assembly is mounted on the base and is used to load the workpiece to be repaired. The heating assembly is connected to the loading assembly and is used to heat the workpiece to be repaired. The packing assembly includes a packing element, a vacuum pump, and a packing pump. The packing element is disposed on the base and opposite to the loading assembly. The packing element and the loading assembly are movable relative to each other, so that the packing element and the workpiece to be repaired abut against each other and together form a packing cavity. The vacuum pump is connected to the packing element for evacuating the packing cavity. The packing pump is connected to the packing element for delivering packing material into the packing cavity.

[0005] In some embodiments, a guide rod is provided on the base. The loading assembly includes a loading unit and a fixing unit. The guide rod passes through the loading unit, and the loading unit is movable on the guide rod to allow the workpiece to be repaired to abut or separate from the packing member. A receiving cavity is provided on the side of the loading unit opposite to the packing member, and the heating assembly is housed in the receiving cavity. The fixing unit is disposed on the side of the loading unit opposite to the packing member, and the fixing unit is at least partially movably connected to the loading unit to selectively fix or release the workpiece to be repaired. When the fixing unit fixes the workpiece to be repaired, the heating assembly contacts the workpiece to be repaired.

[0006] In some embodiments, the loading unit includes a first movable plate, a second movable plate, and a third movable plate. A guide rod passes through the first movable plate, and the first movable plate is movable along a first direction on the guide rod. The second movable plate includes a first side and a second side facing away from each other. The second side of the second movable plate is opposite to the first movable plate, the second movable plate is connected to the first movable plate, and is movable relative to the first movable plate along a second direction. The second movable plate has a first through hole. The third movable plate includes a first side and a second side facing away from each other. The second side of the third movable plate is opposite to the first side of the second movable plate, the third movable plate is connected to the second movable plate, and is movable relative to the second movable plate along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. The third movable plate has a second through hole, and the first through hole and the second through hole form the receiving cavity. The heating assembly is used to limit the travel distance of the second movable plate and the third movable plate.

[0007] In some embodiments, the heating assembly includes a mounting base and a heating element. The mounting base is connected to a first side of the first movable plate and has a mounting cavity. The heating element is installed in the mounting cavity and is used to heat the workpiece to be repaired. When the second movable plate moves, the mounting base abuts against the inner wall of the first through hole to limit the travel of the second movable plate. When the third movable plate moves, the mounting base abuts against the inner wall of the second through hole to limit the travel of the third movable plate.

[0008] In some embodiments, the first movable plate includes a first side and a second side facing away from each other, and the second movable plate is connected to the first side of the first movable plate. The repair device further includes a drive assembly. The drive assembly is disposed on the second side of the first movable plate and connected to the first movable plate. The drive assembly is used to drive the first movable plate to move along the first direction on the guide rod, so that the workpiece to be repaired abuts against or separates from the filler.

[0009] In some embodiments, the first movable plate includes a first side and a second side facing away from each other. The first side of the first movable plate is provided with a first guide member, and the second side of the second movable plate is provided with a first mating member. The first guide member and the first mating member are slidably engaged to guide the second movable plate to move relative to the first movable plate in a second direction.

[0010] In some embodiments, a second guide member is provided on the first side of the second movable plate, and a second mating member is provided on the second side of the third movable plate. The second guide member and the second mating member are slidably engaged to guide the third movable plate to move relative to the second movable plate in a third direction.

[0011] In some embodiments, the fixing unit includes a positioning member and a clamping member. The positioning member is disposed on the third movable plate of the loading unit and forms a limiting space. The limiting space is used to accommodate and restrict the workpiece to be repaired. The clamping member is rotatably connected to the positioning member. When the clamping member rotates into the limiting space, it clamps the workpiece to be repaired onto the third movable plate. When the clamping member rotates out of the limiting space, it releases the workpiece to be repaired, thereby disengaging the workpiece from the third movable plate.

[0012] In some embodiments, the vacuum pump is connected to the packing chamber via a first pipe, and the packing pump is connected to the packing chamber via a second pipe, the second pipe extending through the bottom of the packing chamber. The cross-sectional area of ​​the first pipe is smaller than that of the second pipe.

[0013] In some embodiments, the vacuum pump is connected to the packing cavity via a first conduit to form a flow channel. The packing assembly further includes a barrier. The barrier is mounted on the base and is movable relative to the base to block or open the flow channel. Specifically: when the vacuum pump evacuates the packing cavity, the barrier is in a first position, and the barrier opens the flow channel; after the vacuum pump has evacuated the packing cavity, the barrier is in a second position, and the barrier blocks the flow channel.

[0014] In some embodiments, the packing assembly further includes a seal. The seal is disposed on the side of the packing assembly opposite to the loading assembly and is used to seal the gap between the workpiece to be repaired and the packing assembly.

[0015] In the repair apparatus of this application, after the workpiece to be repaired is loaded into the loading assembly, the heating assembly heats the workpiece to cause the substrate to expand. As the substrate expands, the crack size at the location of the film crack on the substrate surface increases. After the vacuum pump evacuates the packing chamber, the air in the crack is also extracted. When the packing pump delivers packing material into the packing chamber, the vacuum environment allows the packing material to fully fill the crack to repair it. Compared with current repair apparatuses, the repair apparatus of this application allows the packing material to fully penetrate into the crack, resulting in a better crack repair effect.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that the terms "center", "length", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] To improve performance, workpieces typically have a film layer formed on the surface of their substrate. However, because the film layer is harder than the substrate, when the substrate deforms due to external forces, the film layer can break and crack, exposing the substrate beneath. This not only fails to improve the performance of the workpiece at that point but also affects its overall appearance. To address this issue, a repair device can be used to repair the film layer cracks on the substrate, specifically by applying filler to the crack location. However, current repair devices only adhere the filler to the surface of the crack and cannot fully penetrate into the crack's fissure. After wiping away excess filler from the film layer surface, at least part of the crack remains, and the underlying substrate will reappear, resulting in poor crack repair. To solve the above problems, this application provides a repair device (… Figure 1 (As shown).

[0039] Please refer to this as well. Figure 1 and Figure 2 The repair apparatus 100 provided in this application includes a base 10, a loading assembly 30, a heating assembly 50, and a packing assembly 70. The loading assembly 30 is mounted on the base 10 and is used to load the workpiece 300 to be repaired. The heating assembly 50 is connected to the loading assembly 30 and is used to heat the workpiece 300 to be repaired. The packing assembly 70 includes a packing element 71, a vacuum pump 73, and a packing pump 75. The packing element 71 is disposed on the base 10 and opposite to the loading assembly 30. The packing element 71 and the loading assembly 30 are movable relative to each other, so that the packing element 71 and the workpiece 300 to be repaired abut against each other and together form a packing cavity 711. The vacuum pump 73 is connected to the packing element 71 for evacuating the packing cavity 711. The packing pump 75 is connected to the packing element 71 for delivering packing material into the packing cavity 711.

[0040] Specifically, in the above embodiments, the repair device 100 is a device used to repair the workpiece 300 to be repaired. The workpiece 300 to be repaired can be a finished product of electronic products such as mobile phones, tablets, or laptops, or it can be a semi-finished product or raw material for manufacturing electronic products such as mobile phones, tablets, or laptops. The workpiece 300 to be repaired typically includes a substrate. Depending on the application scenario of the workpiece, the material of the substrate can be, but is not limited to, metal or plastic. In order to improve the performance of the workpiece, such as corrosion resistance, wear resistance, and high temperature resistance, the workpiece 300 to be repaired also includes one or more film layers formed on the surface of the substrate. Depending on the substrate, the material and processing technology of the film layer vary. For example, when the substrate is an aluminum substrate, an aluminum oxide film layer can be formed on the surface by anodizing to improve the hardness and wear resistance of the workpiece. During processing, transportation, and use, the workpiece may be subjected to external impact, causing deformation of the substrate. At this time, if the hardness of the film layer is greater than the hardness of the substrate, the film layer may be damaged and cracks may form. At the location where a crack forms in the film layer, the substrate beneath the film layer is directly exposed. The workpiece in this state is a type of workpiece 300 to be repaired. The cracked area in the film layer of the workpiece 300 will not achieve the desired performance improvement, and the overall appearance of the workpiece 300 will be unsatisfactory. Therefore, the repair device 100 provided in this application is needed to repair the crack in the film layer of the workpiece 300 to restore its performance.

[0041] The base 10 is a structure used to support other components in the repair device 100. In this application, the loading assembly 30, heating assembly 50, and packing assembly 70 in the repair device 100 can be supported on the base 10. These other components can be disposed outside or inside the base 10. For example, the loading assembly 30 and heating assembly 50 are disposed outside the base 10, while some components of the packing assembly 70 are disposed outside the base 10 and others are disposed inside the base 10, with the base 10 providing protection for the components disposed inside.

[0042] In this application, the base 10 includes a housing 11. The housing 11 has a receiving cavity 110 and includes a top 111, a bottom 113, and a side 115. The top 111 and the bottom 113 are spaced apart and opposite each other, and in the normal use state where the repair device 100 is placed on the ground, the bottom 113 is closer to the ground than the top 111. The side 115 connects the periphery of the top 111 and the bottom 113, and together with the top 111 and the bottom 113, forms the receiving cavity 110. The receiving cavity 110 is used to accommodate at least some of the aforementioned other components.

[0043] Furthermore, in some embodiments, the base 10 may also include a support member 13, which is disposed at the bottom 113 and used to support the outer casing 11 on the ground. The support member 13 can raise the bottom 113 away from the ground, thereby providing a lifting and waterproofing function. In other embodiments, the base 10 may also include casters (not shown), which are disposed at the bottom 113 and can roll or slide on the ground to move the outer casing 11 and other components disposed on the outer casing 11 together, which is beneficial for the transportation of the repair device 100.

[0044] The material of the outer casing 11 includes, but is not limited to, metal, plastic, or a combination of both. When the outer casing 11 is made of metal, it has high structural strength, is not easily damaged, and provides better protection for other components housed within it, resulting in a long service life for the repair device 100. When the outer casing 11 is made of plastic, it is lighter and less expensive, giving the repair device 100 a lightweight advantage.

[0045] Please combine Figure 3 and Figure 4 The loading assembly 30 is a component in the repair device 100 used for loading or unloading the workpiece 300 to be repaired. The loading assembly 30 is mounted on the base 10. In this application, the repair device 100 also includes a guide rod 81 and a guide sleeve 83. The guide rod 81 is disposed on the top 111 of the base 10, and the guide sleeve 83 is sleeved on the guide rod 81. The loading assembly 30 is mounted on the top 111 of the base 10 via the guide rod 81 and the guide sleeve 83. The workpiece 300 to be repaired is detachably loaded onto the loading assembly 30. Specifically, when using the repair device 100 to repair the workpiece 300, the workpiece 300 is loaded onto the loading assembly 30; after the repair device 100 completes the repair of the workpiece 300, the workpiece 300 can be removed from the loading assembly 30. Thus, the repair device 100 can repeatedly repair multiple workpieces 300 to be repaired.

[0046] The heating component 50 is a component in the repair device 100 used to heat the workpiece 300 to be repaired. The heating component 50 can heat the workpiece 300 using, but is not limited to, electric heating, laser heating, plasma heating, and electromagnetic heating. When the heating component 50 uses electric heating to heat the workpiece 300, this method has the advantages of simple structure and low cost. When the heating component 50 uses laser heating to heat the workpiece 300, this method has the advantages of high heating precision and ease of small-area localized heating. When the heating component 50 uses plasma heating to heat the workpiece 300, this method has the advantages of high heating energy and extremely high heating temperature. When the heating component 50 uses electromagnetic heating to heat the workpiece 300, this method has the advantages of high energy utilization and precise heating range. The heating component 50 and the loading component 30 can be detachably connected, for example, by threaded connection, snap-fit ​​connection, or a combination of threaded connection and snap-fit ​​connection; the heating component 50 and the loading component 30 can also be non-detachably connected, for example, by welding, gluing, or a combination of welding and gluing. When the heating assembly 50 heats the workpiece 300 to be repaired, the workpiece 300 expands due to heat, increasing the size of the crack, which facilitates the subsequent extraction of air from the crack and the filling of the crack with filler. It should be noted that the explanations of "detachable connection" and "non-detachable connection" here apply throughout the text and will not be elaborated further.

[0047] Please refer to the following: Figure 2 and Figure 5 The filler assembly 70 is an assembly in the repair device 100 used to fill the cracks in the workpiece 300 to be repaired with filler. The filler is a filling material used to repair the cracks in the workpiece 300; this filler material has a certain degree of fluidity and can be in a liquid or gel state. Depending on the properties of the workpiece 300 to be repaired and the properties of the crack, the filler may contain one or more functional substances to give the filler different properties. For example, the filler may contain a binder to enable the filler to bond more firmly to the periphery of the crack. Another example is that the filler may contain a curing agent that cures upon exposure to a UV lamp, allowing for rapid curing after the filler has filled the crack.

[0048] The packing element 71 is a specific component in the packing assembly 70 used to accommodate the packing and provide conditions for contact between the packing and the crack. The packing element 71 is connected to the base 10, and the connection between the packing element 71 and the base 10 can be detachable or non-detachable. Specifically, the packing element 71 is connected to the top 111 of the base 10 and is located outside the base 10. If the height direction of the repair device 100, that is, the direction in which the base 10 and the loading assembly 30 are opposite, is defined as the first direction H, then the packing element 71 is opposite to the loading assembly 30 in the first direction H. At the same time, the packing element 71 and the loading assembly 30 can move relative to each other, so the packing element 71 can abut or separate from the workpiece 300 to be repaired loaded on the loading assembly 30 in the first direction H.

[0049] More specifically, in some embodiments, the loading assembly 30 is fixed relative to the ground, while the filler 71 can move relative to the loading assembly 30 in the first direction H, for example, moving closer to or away from the loading assembly 30, thereby achieving the abutment or separation of the filler 71 from the workpiece 300 to be repaired. In other embodiments, the filler 71 is fixed relative to the ground, while the loading assembly 30 can move relative to the filler 71 in the first direction H, for example, moving closer to or away from the filler 71, thereby achieving the abutment or separation of the workpiece 300 to be repaired from the filler 71. In still other embodiments, both the filler 71 and the loading assembly 30 can move relative to the ground, for example, moving closer to or away from each other, which also achieves the abutment or separation of the workpiece 300 to be repaired from the filler 71. When the workpiece 300 to be repaired abuts the filler 71, a sealed filling cavity 711 can be formed between the workpiece 300 to be repaired and the filler 71. The filling cavity 711 is a spatial structure used to accommodate the filler when repairing cracks and fissures. To ensure adequate repair of the crack, when the workpiece 300 to be repaired abuts against the packing member 71, the crack and the packing cavity 711 are aligned and connected to ensure that the packing in the packing cavity 711 can fully penetrate the crack. When the workpiece 300 to be repaired is separated from the packing member 71, the sealing state of the packing cavity 711 is broken, and outside air can enter the packing member 71.

[0050] Vacuum pump 73 is a component in the packing assembly 70 used to create a vacuum environment in the packing cavity 711. Vacuum pump 73 is connected to packing member 71, and a first flow path for gas flow is provided between them. Vacuum pump 73 extracts air from the packing cavity 711 through the first flow path to create a vacuum state within the packing cavity 711. At this time, air in the crevices is also extracted, and the crevices are fully exposed in the packing cavity 711 and are also in a vacuum state. Furthermore, vacuum pump 73 can be disposed at any position on the base 10; in this application, vacuum pump 73 is disposed in the receiving cavity 110 of the base 10.

[0051] The packing pump 75 is a component in the packing assembly 70 used to deliver packing material into the packing cavity 711. The packing pump 75 is connected to the packing element 71, and a second flow path is provided between them for the packing material to circulate. After the vacuum pump 73 evacuates the packing cavity 711, the packing pump 75 can deliver packing material into the packing cavity 711 through the second flow path, filling the entire packing cavity 711. At this time, because the packing cavity 711 is under vacuum, the packing material can fully fill the cracks in the workpiece 300 to repair the cracks. After the workpiece 300 is repaired, the packing pump 75 can also re-pump the unused packing material (packing material that did not fill the cracks) in the packing element 71, realizing the reuse of the packing material, saving packing material and reducing costs. Furthermore, the packing pump 75 can be installed at any position on the base 10; in this application, the vacuum pump 73 is installed in the receiving cavity 110 of the base 10.

[0052] Furthermore, in some embodiments, the packing assembly 70 may also include a packing bin 79, which is a container for storing packing material. The packing bin 79 is connected to a packing pump 75 so that the packing pump 75 can inject the packing material from the packing bin 79 into the packing cavity 711, or suck back unused packing material from the packing member 71 to the packing bin 79. Similarly, the packing bin 79 can be located at any position on the base 10. In this application, the packing bin 79 is located in the receiving cavity 110 of the base 10. In other embodiments, the packing assembly 70 may not include a packing bin 79, and the packing pump 75 may be connected to a device for storing packing material located outside the repair device 100.

[0053] In the repair apparatus 100 of this application, after the workpiece 300 to be repaired is loaded into the loading assembly 30, the heating assembly 50 can heat the workpiece 300 to cause the substrate of the workpiece 300 to expand. As the substrate expands, the crack size at the location of the film crack on the substrate surface increases. After the vacuum pump 73 evacuates the filling chamber 711, the air in the crack is also extracted. When the filling pump 75 transfers the filling material into the filling chamber 711, the vacuum environment allows the filling material to fully fill the crack to repair the crack on the workpiece 300. Compared with the current repair apparatus, the repair apparatus 100 of this application can make the filling material fully penetrate into the crack, resulting in a better crack repair effect.

[0054] Please refer to Figure 1 and Figure 2In some embodiments, a guide rod 81 is provided on the base 10. The loading assembly 30 includes a loading unit 31 and a fixing unit 33. The guide rod 81 passes through the loading unit 31, and the loading unit 31 is movable on the guide rod 81 to allow the workpiece 300 to be repaired to abut or separate from the filler 71. A receiving cavity 311 is provided on the side of the loading unit 31 opposite to the filler 71, and the heating assembly 50 is housed in the receiving cavity 311. The fixing unit 33 is disposed on the side of the loading unit 31 opposite to the filler 71 and is movably connected to the loading unit 31. The fixing unit 33 can selectively fix or release the workpiece 300 to be repaired. When the fixing unit 33 fixes the workpiece 300 to be repaired, the heating assembly 50 contacts the workpiece 300 to be repaired.

[0055] Please combine Figure 3 and Figure 4 The loading unit 31 is provided with guide holes 3135 for the guide rods 81 to pass through. The number, size, and position of the guide holes 3135 need to correspond to the number, size, and position of the guide rods 81, so that the loading unit 31 can move along the first direction H on the guide rods 81. At this time, the workpiece 300 to be repaired loaded on the loading assembly 30 can abut against or separate from the filling member 71. The loading unit 31 has a receiving cavity 311 on one side opposite to the filling member 71. The receiving cavity 311 is a spatial structure for installing the heating assembly 50. The volume of the receiving cavity 311 matches the size of the heating assembly 50, specifically, the volume of the receiving cavity 311 is greater than or equal to the size of the heating assembly 50. In order to uniformly heat the workpiece 300 to be repaired, the receiving cavity 311 can be opened in the middle area of ​​the loading unit 31, and the heating assembly 50 is set in the middle area of ​​the receiving cavity 311.

[0056] When the repair device 100 is repairing the workpiece 300, the loading unit 31 moves on the guide rod 81 and holds the workpiece 300 against the packing member 71. At this time, the workpiece 300 and the packing member 71 form a sealed packing cavity 711. The vacuum pump 73 can evacuate the packing cavity 711, and the packing pump 75 can deliver packing to the vacuumed packing cavity 711 to fill the crack, thereby repairing the crack in the workpiece 300. After the repair device 100 has repaired the workpiece 300, the loading unit 31 moves on the guide rod 81 and separates the workpiece 300 from the packing member 71, moving them away from each other. The vacuum in the packing cavity 711 is broken, and the packing pump 75 can more easily extract the unused packing from the packing cavity 711.

[0057] The fixing unit 33 is a component used to fix the workpiece 300 to be repaired onto the loading unit 31. In the first direction H, both the fixing unit 33 and the workpiece 300 to be repaired are disposed on the side of the loading unit 31 opposite to the packing member 71. At least a portion of the fixing unit 33 is movably connected to the loading unit 31, at which time the relative position of at least a portion of the fixing unit 33 and the loading unit 31 can change to fix or release the workpiece 300 to be repaired. When the repair device 100 is repairing the workpiece 300, the fixing unit 33 fixes the workpiece 300 to be repaired onto the loading unit 31, and the workpiece 300 to be repaired can directly contact the heating component 50 located in the accommodating cavity 311. At this time, the heat of the heating component 50 can be quickly transferred to the workpiece 300 to be repaired, and the temperature of the workpiece 300 to be repaired can be quickly raised to the preset temperature required for crack expansion, such as 60°C. The heating component 50 has high energy utilization, shortens the heating time during the repair process, and improves the repair efficiency.

[0058] Please refer to Figures 2 to 4 In some embodiments, the loading unit 31 includes a first movable plate 313, a second movable plate 315, and a third movable plate 317. A guide rod 81 passes through the first movable plate 313, which is movable along a first direction H. The second movable plate 315 includes a first side 3151 and a second side 3152 facing each other. The second side 3152 of the second movable plate is opposite to the first movable plate 313, and the second movable plate 315 is connected to the first movable plate 313 and is movable relative to the first movable plate 313 along a second direction L. The second movable plate 315 has a first through hole 3153. The third movable plate 317 includes a first side 3171 and a second side 3172 facing each other. The second side 3172 of the third movable plate is opposite to the first side 3151 of the second movable plate, and the third movable plate 317 is connected to the second movable plate 315 and is movable relative to the second movable plate 315 along a third direction W. The first direction H, the second direction L, and the third direction W are perpendicular to each other. The third movable plate 317 is provided with a second through hole 3173, and the first through hole 3153 and the second through hole 3173 form a receiving cavity 311. The heating assembly 50 is used to limit the movement stroke of the second movable plate 315 and the third movable plate 317.

[0059] Specifically, in the above embodiment, the loading unit 31 achieves relative movement with the filler 71 by setting a structure of a first movable plate 313, a second movable plate 315 and a third movable plate 317, so that the cracked area of ​​the workpiece 300 to be repaired can be aligned with the filler 71 in the first direction H.

[0060] The first movable plate 313 is a structure in the loading unit 31 that can move in the first direction H. A guide hole 3135 is provided on the first movable plate 313 so that the guide rod 81 passes through the guide hole 3135 and through the first movable plate 313. Figure 3 As shown. The first movable plate 313 includes a first side 3131 and a second side 3132 that are opposite to each other in the first direction L. The first side 3131 of the first movable plate 313 is opposite to the base 10. The guide sleeve 83 is sleeved on the guide rod 81 and supports the first side 3131 of the first movable plate. The frictional force between the guide sleeve 83 and the guide rod 81 is greater than the frictional force between the first movable plate 313 and the guide rod 81. On the one hand, the cooperation between the guide rod 81 and the guide hole 313 can guide the loading assembly 30 when it moves along the first direction H, making the movement of the loading assembly 30 smoother and more stable. On the other hand, the guide sleeve 83 supports the first movable plate 313, and the friction between the guide sleeve 83 and the guide rod 81 is greater than the friction between the first movable plate 313 and the guide rod 81, which makes the movement of the first movable plate 313 relative to the guide rod 81 more stable, and after the loading assembly 30 reaches any desired target position in the first direction H, it can be stabilized at that target position.

[0061] The second movable plate 315 is a structure in the loading unit 31 that can move in the second direction L. If the length direction of the repair device 100 is defined as the second direction L, and the width direction of the repair device 100 is defined as the third direction W, then the first direction H, the second direction L, and the third direction W are perpendicular to each other. In the first direction H, the second movable plate 315 includes a first side 3151 and a second side 3152 facing away from each other, wherein the side opposite to the filling member 71 is the first side 3151 of the second movable plate, and the side opposite to the first movable plate 313 is the second side 3152 of the second movable plate. The second movable plate 315 is movably connected to the first movable plate 313, specifically, the second movable plate 315 can move relative to the first movable plate 313 in the second direction L.

[0062] The third movable plate 317 is a structure in the loading unit 31 that can move in a third direction W. In the first direction H, the third movable plate 317 includes a first side 3171 and a second side 3172 facing away from each other, wherein the side opposite to the packing member 71 is the first side 3171 of the third movable plate, and the side opposite to the second movable plate 315 is the second side 3172 of the third movable plate. The third movable plate 317 is movably connected to the second movable plate 315, specifically, the third movable plate 317 can move relative to the second movable plate 315 in the third direction W. The workpiece 300 to be repaired is fixed on the third movable plate 317.

[0063] In the repair device 100 of this application embodiment, the third movable plate 317 moves relative to the second movable plate 315 in the third direction W, which can drive the workpiece 300 to be repaired to move relative to the filler 71 in the third direction W. The second movable plate 315 moves relative to the first movable plate 313 in the second direction L, which can drive the workpiece 300 to be repaired to move relative to the filler 71 in the second direction L. The first movable plate 313 moves relative to the base 10 in the first direction H, which can drive the workpiece 300 to be repaired to move relative to the filler 71 in the first direction H. As a result, the cracked area of ​​the film layer on the workpiece 300 to be repaired can be aligned with the filler 71, and the subsequent repair of the crack is more accurate.

[0064] The first through hole 3153 is a spatial structure on the second movable plate 315 used to make way for the heating component 50. The size of the first through hole 3153 needs to match the size of the heating component 50 and the travel distance of the second movable plate 315 relative to the first movable plate 313. The second through hole 3173 is a spatial structure on the third movable plate 317 used to make way for the heating component 50. The size of the second through hole 3173 needs to match the size of the heating component 50 and the travel distance of the third movable plate 317 relative to the second movable plate 315. The first through hole 3153 and the second through hole 3173 together form a receiving cavity 311, in which the heating component 50 is disposed. At this time, during the movement of the second movable plate 315 relative to the first movable plate 313 along the second direction L, the heating component 50 can limit the movement stroke of the second movable plate 315 relative to the first movable plate 313, thereby preventing the second movable plate 315 from moving too far and disengaging from the first movable plate 313. Similarly, during the movement of the third movable plate 317 relative to the second movable plate 315 along the third direction W, the heating component 50 can also limit the movement stroke of the third movable plate 317 relative to the second movable plate 315, thereby preventing the third movable plate 317 from moving too far and disengaging from the second movable plate 315.

[0065] Further, please refer to Figures 2 to 4 In some embodiments, the heating assembly 50 may include a mounting base 51 and a heating element 53. The mounting base 51 is connected to a first side 3131 of the first movable plate and has a mounting cavity 511. The heating element 53 is mounted in the mounting cavity 511 and is used to heat the workpiece 300 to be repaired. When the second movable plate 315 moves, the mounting base 51 abuts against the inner wall of the first through hole 3153 to limit the travel of the second movable plate 315. When the third movable plate 317 moves, the mounting base 51 abuts against the inner wall of the second through hole 3173 to limit the travel of the third movable plate 317.

[0066] Specifically, in the above embodiment, the heating element 53 is a component in the heating assembly 50 used to heat the workpiece 300 to be repaired. Depending on the heating method, the heating element 53 can be different components, such as a heating film, a heating tube, a thermocouple, and a heating coil.

[0067] Mounting base 51 is a structure in heating assembly 50 used to mount and protect heating element 53. Mounting base 51 is fixedly connected to the first side 3131 of the first movable plate. The connection between mounting base 51 and the first movable plate 313 can be detachable or non-detachable. Mounting base 51 is provided with mounting cavity 511 for mounting heating element 53. The size and shape of mounting cavity 511 are respectively matched with the size and shape of heating element 53, ensuring that heating element 53 is completely contained inside mounting base 51 in the second direction L and the third direction W. That is, heating element 53 does not protrude from the outside of mounting base 51 in the second direction L, nor does heating element 53 protrude from the outside of mounting base 51 in the third direction W.

[0068] In some embodiments, the mounting base 51 may be made of a thermally conductive material, and the workpiece 300 to be repaired contacts the mounting base 51 and / or the heating element 53 in the first direction H. Specifically, in one example, the workpiece 300 to be repaired only contacts the heating element 53 in the first direction H, in which case the heating element 53 directly transfers heat to the workpiece 300 to be repaired. In another example, the workpiece 300 to be repaired only contacts the mounting base 51 in the first direction H, and the heating element 53 directly transfers heat to the mounting base 51, and then the mounting base 51 transfers it to the workpiece 300 to be repaired. In this case, the mounting base 51 can increase the contact area with the workpiece 300 to be repaired, making the heated area of ​​the workpiece 300 to be repaired larger, and enabling the workpiece 300 to be repaired to be heated quickly and uniformly. In some other examples, the workpiece 300 to be repaired not only contacts the heating element 53 in the first direction H, but also contacts the mounting base 51. At this time, part of the heat generated by the heating element 53 is directly transferred to the workpiece 300 to be repaired, and the other part is first transferred to the mounting base 51, and then transferred to the workpiece 300 to be repaired by the mounting base 51. At this time, the setting of the mounting base 51 also increases the contact area with the workpiece 300 to be repaired, making the heated area of ​​the workpiece 300 to be repaired larger, and enabling the workpiece 300 to be repaired to be heated quickly and evenly.

[0069] When the second movable plate 315 moves relative to the first movable plate 313 in the second direction L, the relative position of the second movable plate 315 and the mounting base 51 changes. At this time, the mounting base 51 can abut against the inner wall of the first through hole 3153, thereby limiting the movement stroke of the second movable plate 315 and preventing the second movable plate 315 from falling off the first movable plate 313. Moreover, since the heating element 53 does not protrude from the outside of the mounting base 51 in the second direction L, when the second movable plate 315 moves relative to the first movable plate 313 along the second direction L and its stroke is limited by the heating assembly 50, the heating element 53 will not collide with the second movable plate 315. Only the mounting base 51 plays the role of limiting the stroke, thus protecting the heating element 53 from damage. Similarly, when the third movable plate 317 moves relative to the second movable plate 315 in the third direction W, the relative position of the third movable plate 317 and the mounting base 51 changes. At this time, the mounting base 51 can abut against the inner wall of the second through hole 3173, thereby limiting the movement stroke of the third movable plate 317 and preventing the third movable plate 317 from falling off the second movable plate 315. Moreover, since the heating element 53 does not protrude from the outside of the mounting base 51 in the third direction W, when the third movable plate 317 moves relative to the second movable plate 315 in the third direction W and its stroke is limited by the heating assembly 50, the heating element 53 will not collide with the third movable plate 317. Only the mounting base 51 plays the role of limiting the stroke, thus protecting the heating element 53 from damage.

[0070] In summary, on the one hand, the mounting base 51 limits the travel of the second movable plate 315 and the third movable plate 317. On the other hand, the mounting base 51 protects the heating element 53, preventing damage to the heating element 53 during movement by the second movable plate 315 and the third movable plate 317, thus extending the service life of the repair device 100.

[0071] Please refer to Figures 2 to 4 In some embodiments, the first movable plate 313 includes a first side 3131 and a second side 3132 facing away from each other, and a second movable plate 315 is connected to the first side 3131 of the first movable plate. The repair device 100 also includes a (first) drive assembly 20. The drive assembly 20 is disposed on the second side 3132 of the first movable plate and connected to the first movable plate 313. The drive assembly 20 is used to drive the first movable plate 313 to move along a first direction H on the guide rod 81, so that the workpiece 300 to be repaired abuts against or separates from the filler 71.

[0072] Specifically, in the above embodiment, the drive assembly 20 is a structure for driving the first movable plate 313 to move along the first direction H on the guide rod 81. The repair device 100 also includes a support plate 90, which is used to fix and install the drive assembly 20. Specifically, the drive assembly 20 includes a driveable element 21 and a connecting element 23. The drive element 21 is an element for driving the first movable plate 313 to move. In the repair device 100 of this application, the drive element 21 is a cylinder and includes a cylinder barrel 211 and a piston rod 213. The cylinder barrel 211 is an element for realizing air pressure regulation. The piston rod 213 is an element that can move relative to the cylinder barrel 211. The piston rod 213 is movably connected to the cylinder barrel 211 so that the cylinder barrel 211 drives the piston rod 213 to move in the first direction H by adjusting the internal air pressure. The connecting element 23 is a device for connecting the piston rod 213 in the drive assembly 21 and the second side 3132 of the first movable plate. The connector 23 can transmit the movement of the piston rod 213 in the first direction H to the first movable plate 313.

[0073] The connection between the connector 23 and the piston rod 213 can be a detachable or non-detachable connection. In some embodiments, a threaded hole is provided on the side of the connector 23 opposite to the piston rod 213, and a thread is provided on the end of the piston rod 213 near the connector 23. The thread engages with the threaded hole to connect the connector 23 and the piston rod 213. In other embodiments, a connecting post is provided on the side of the connector 23 opposite to the piston rod 213. The outer wall of the connecting post is threaded, and a threaded hole is provided on the end of the piston rod 213 near the connector 23. The thread engages with the threaded hole to connect the connector 23 and the piston rod 213.

[0074] The connection between the connector 23 and the first movable plate 313 can be either detachable or non-detachable. In some embodiments, the connector 23 has a threaded hole on the side opposite to the first movable plate 313, and the second side 3132 of the first movable plate has a connecting post. The outer wall of the connecting post is threaded, and the thread engages with the threaded hole to connect the connector 23 to the first movable plate 313. In other embodiments, the connector 23 has a connecting post on the side opposite to the first movable plate 313, and the outer wall of the connecting post is threaded. The first movable plate 313 has a threaded hole, and the thread engages with the threaded hole to connect the connector 23 to the first movable plate 313. Although the drive member 21 and the first movable plate 313 can be directly connected, due to space limitations within the repair device 100, a direct connection between the two may not be feasible. Therefore, in this embodiment, the driving component 21 is connected to the first movable plate 313 through the connecting component 23. That is, the driving component 21 and the first movable plate 313 are connected by the connecting component 23. The connection process only requires operating (rotating) the connecting component 23, without the need for a large operating space, making the connection simpler and more convenient.

[0075] When the drive assembly 20 drives the first movable plate 313 to move along the first direction H on the guide rod 81 and approach the filler 71, the workpiece 300 to be repaired can abut against the filler 71; when the drive assembly 20 drives the first movable plate 313 to move along the first direction H on the guide rod 81 and away from the filler 71, the workpiece 300 to be repaired can separate from the filler 71. Therefore, the drive assembly 20 can adjust the relative positional relationship between the workpiece 300 to be repaired and the filler 71 to match the working process of the repair device 100.

[0076] Please refer to Figures 2 to 4 In some embodiments, the first movable plate 313 includes a first side 3131 and a second side 3132 facing away from each other. The first side 3131 of the first movable plate is provided with a first guide member 3133, and the second side 3152 of the second movable plate is provided with a first mating member 3155. The first guide member 3133 and the first mating member 3155 are slidably engaged to guide the second movable plate 315 to move relative to the first movable plate 313 along a second direction L.

[0077] Specifically, in the above embodiments, the first guide member 3133 is an element on the first movable plate 313 that cooperates with the first mating member 3155 to guide the movement of the second movable plate 315. The first guide member 3133 is disposed on the first side 3131 of the first movable plate. The first mating member 3155 is an element on the second movable plate 315 that cooperates with the first guide member 3133 to perform a guiding function. The first mating member 3155 is disposed on the second side 3152 of the second movable plate. In some embodiments, the first guide member 3133 is a guide rail, and the first mating member 3155 is a guide rail groove. The guide rail is accommodated in the guide rail groove and can slide in the guide rail groove to achieve a sliding engagement between the first guide member 3133 and the first mating member 3155. In other embodiments, the first guide member 3133 is a guide rail groove, and the first mating member 3155 is a guide rail. The guide rail is housed in the guide rail groove and can slide in the groove to achieve a sliding engagement between the first guide member 3133 and the first mating member 3155. The repair device 100 of this application, through the engagement of the first guide member 3133 and the first mating member 3155, enables the second movable plate 315 to move relative to the first movable plate 313 in the second direction L, thereby enabling the workpiece 300 to be repaired to move relative to the filler member 71 in the second direction L, so that the crack in the workpiece 300 to be repaired is aligned with the filler member 71.

[0078] Please refer to Figures 2 to 4In some embodiments, the first side 3151 of the second movable plate is provided with a second guide 3157, and the second side 3172 of the third movable plate is provided with a second mating member 3175. The second guide 3157 and the second mating member 3175 are slidably engaged to guide the third movable plate 317 to move relative to the second movable plate 315 along a third direction W.

[0079] Specifically, in the above embodiments, the second guide member 3157 is an element on the second movable plate 315 that cooperates with the second mating member 3175 to guide the movement of the third movable plate 317. The second guide member 3157 is disposed on the first side 3151 of the second movable plate. The second mating member 3175 is an element on the third movable plate 317 that cooperates with the second guide member 3157 to perform a guiding function. The second mating member 3175 is disposed on the second side 3172 of the third movable plate. In some embodiments, the second guide member 3157 is a guide rail, and the second mating member 3175 is a guide rail groove. The guide rail is accommodated in the guide rail groove and can slide in the guide rail groove to achieve a sliding engagement between the second guide member 3157 and the second mating member 3175. In other embodiments, the second guide member 3157 is a guide groove, and the second mating member 3175 is a guide rail. The guide rail is housed in the guide groove and can slide in the guide groove to achieve a sliding engagement between the second guide member 3157 and the second mating member 3175. The repair device 100 of this application, through the engagement of the second guide member 3157 and the second mating member 3175, enables the third movable plate 317 to move relative to the second movable plate 315 in a third direction W, thereby enabling the workpiece 300 to be repaired to move relative to the filler member 71 in a third direction W, so that the crack in the workpiece 300 to be repaired is further aligned with the filler member 71.

[0080] In some embodiments, the repair device 100 further includes a second drive assembly (not shown) and a third drive assembly (not shown). The second drive assembly is connected to a second movable plate 315 to drive the second movable plate 315 to move relative to the first movable plate 313 along a second direction L. The third drive assembly is connected to a third movable plate 317 to drive the third movable plate 317 to move relative to the second movable plate 315 along the second direction L.

[0081] Please refer to Figures 2 to 4In some embodiments, the fixing unit 33 may include a positioning member 331 and a clamping member 333. The positioning member 331 is disposed on the third movable plate 317 of the loading unit 31 and forms a limiting space 3311. The limiting space 3311 is used to accommodate and restrict the workpiece 300 to be repaired. The clamping member 333 is rotatably connected to the positioning member 331. When the clamping member 333 rotates to the inside of the limiting space 3311, the clamping member 333 clamps the workpiece 300 to be repaired onto the third movable plate 317. When the clamping member 333 rotates to the outside of the limiting space 3311, the clamping member 333 releases the workpiece 300 to be repaired, so that the workpiece 300 to be repaired is disengaged from the third movable plate 317.

[0082] Specifically, in the above embodiments, the number of fixing units 33 can be one or more. To better fix the workpiece 300 to be repaired while also saving costs, this application only illustrates the case where the number of fixing units 33 is four. The positioning element 331 is a component used to position the workpiece 300 to be repaired at the installation position of the third movable plate 317. The positioning element 331 is disposed on the first side 3171 of the third movable plate, and the positioning element 331 and the third movable plate 317 can be an integral structure or a separate structure. When the positioning element 331 and the third movable plate 317 are an integral structure, the connection between them is tighter, and the fixing unit 33 can better fix the workpiece 300 to be repaired. When the positioning element 331 and the third movable plate 317 are separate structures, the mold structure for manufacturing the positioning element 331 and the third movable plate 317 is simple, and the connection between the positioning element 331 and the third movable plate 317 is more flexible. The spatial structure formed between the four positioning elements 331 is the limiting space 3311. The limiting space 3311 is a spatial structure used to accommodate and restrict the workpiece 300 to be repaired. The size and shape of the limiting space 3311 are respectively matched with the size and shape of the workpiece 300 to be repaired so that the workpiece 300 to be repaired can be stably fixed by the fixing unit 33.

[0083] The clamping element 333 is a component used to fix the workpiece 300 to be repaired within the limiting space 3311. The clamping element 333 is rotatably connected to the positioning element 331. In some embodiments, the clamping element 333 has a rotating shaft, and the positioning element 331 has a rotating shaft hole, in which the rotating shaft is rotatably installed, so that the clamping element 333 is rotatably connected to the positioning element 331. In some embodiments, the clamping element 333 has a rotating shaft hole, and the positioning element 331 has a rotating shaft, in which the rotating shaft is rotatably installed, so that the clamping element 333 is rotatably connected to the positioning element 331. When the clamping element 333 rotates into the limiting space 3311, the portion of the clamping element 333 extending relative to the positioning element 331 abuts against the workpiece 300 to be repaired, thereby fixing the workpiece 300 to be repaired on the third movable plate 317. When the clamping member 333 rotates outside the limiting space 3311, the clamping member 333 separates from the workpiece 300 to be repaired and releases the workpiece 300 to be repaired, allowing the workpiece 300 to detach from the third movable plate 317. The repair device 100 of this application uses the positioning member 331 to position the workpiece 300 to be repaired and uses the fixing unit 33 to selectively fix or release the workpiece 300 to be repaired, so that the workpiece 300 to be repaired can be easily loaded onto the transfer assembly 30 and easily removed from the transfer assembly 30.

[0084] Please refer to Figure 5 and Figure 6 In some embodiments, vacuum pump 73 is connected to packing chamber 711 via first pipe 731, and packing pump 75 is connected to packing chamber 711 via second pipe 751, the second pipe 751 passing through the bottom of packing chamber 711. The cross-sectional area of ​​first pipe 731 is smaller than the cross-sectional area of ​​second pipe 751.

[0085] Specifically, in the above embodiment, the first pipe 731 is used to connect the vacuum pump 73 and the stuffing chamber 711. The first pipe 731 is connected to the bottom or side of the stuffing member 71. The second pipe 751 is used to connect the stuffing pump 75 and the stuffing chamber 711. The second pipe 751 is connected to the bottom of the stuffing member 71, that is, the second pipe 751 passes through the bottom of the stuffing chamber 711. At this time, during the process of the stuffing pump 75 re-suctioning the packing, due to the gravity of the packing, the re-suction of the packing becomes easier, and less packing remains in the stuffing member 71 after re-suction. The second pipe 751 is a certain distance away from the first pipe 731. Moreover, since the first pipe 731 is used to transport gas and the second pipe 751 is used to transport packing, the cross-sectional area of ​​the first pipe 731 is smaller than the cross-sectional area of ​​the second pipe 751. At this point, although the cross-sectional area of ​​the first pipe 731 is designed to be relatively small, since it is used for gas transmission, it can save installation space and reduce material costs of the first pipe 731 while ensuring that the vacuum pump 73 can perform vacuuming of the stuffing chamber 711. The cross-sectional area of ​​the second pipe 751 is designed to be relatively large, making the process of the stuffing pump 75 injecting packing into the stuffing component 71 and the process of packing back flow more smoothly and in less time.

[0086] Please refer to Figure 5 and Figure 6 In some embodiments, the vacuum pump 73 is connected to the packing chamber 711 via a first conduit 731 to form a flow channel 7311. The packing assembly 70 also includes a barrier 77. The barrier 77 is mounted on the base 10 and is movable relative to the base 10 to block or open the flow channel 7311. When the vacuum pump 73 evacuates the packing chamber 711, the barrier 77 is in a first position, and the barrier 77 opens the flow channel 7311; after the vacuum pump 73 has evacuated the packing chamber 711, the barrier 77 is in a second position, and the barrier 77 blocks the flow channel 7311.

[0087] Specifically, in the above embodiments, the barrier 77 is a component used to block or open the flow channel 7311. The barrier 77 is mounted on the base 10 and is movable relative to the base 10. During the movement of the barrier 77 relative to the base 10, it can selectively block or open the flow channel 7311. In some embodiments, the barrier 77 is a cylinder, in which case the rod-like structure in the cylinder can extend into or out of the flow channel 7311 to achieve selective blocking or opening of the flow channel 7311. In other embodiments, the barrier 77 is a movable plug-in post, in which case the plug-in post can extend into or out of the flow channel 7311 to achieve selective blocking or opening of the flow channel 7311.

[0088] During the evacuation process of the vacuum pump 73 into the packing chamber 711, the barrier 77 opens the flow channel 7311 to allow the vacuum pump 73 to extract air from the packing chamber 711. During the evacuation process, the barrier 77 is in its first position. After the vacuum pump 73 has completed evacuating the packing chamber 711, the barrier 77 blocks the flow channel 7311 to prevent packing from flowing into the flow channel 7311 and contaminating the vacuum pump 73 during the injection of packing into and / or re-suction of packing from the packing chamber 711, thus preventing damage to the vacuum pump 73. At this time, the barrier 77 is in its second position. In summary, the barrier 77 can switch between the first and second positions to achieve the opening and blocking of the flow channel 7311. The barrier 77 protects the flow channel 7311 and the vacuum pump 73, improving the reliability of the repair device 100.

[0089] Please refer to Figure 5 Furthermore, in some embodiments, the packing assembly 70 may also include a seal 78. The seal 78 is disposed on the side of the packing member 71 opposite to the loading assembly 30 and is used to seal the gap between the workpiece 300 to be repaired and the packing member 71.

[0090] During the process of forming a sealed packing cavity 711 by fitting the packing member 71 with the workpiece 300 to be repaired, if there is a gap between the packing member 71 and the workpiece 300, the sealing performance of the packing cavity 711 will be affected. In this case, the vacuum pump 73 will be unable to evacuate the packing cavity 711 to a vacuum state, and the packing pump 75 may also cause packing overflow during the injection of packing into the packing cavity 711. The repair device 100 will then be unable to properly repair the workpiece 300. Therefore, a sealing element 78 is provided in the packing assembly 70. The sealing element 78 is a component used to seal any gaps that may exist between the packing member 71 and the workpiece 300 to be repaired. The sealing element 78 can be, but is not limited to, a sealing rubber ring. The sealing element 78 is located on the side of the packing member 71 opposite to the loading assembly 30.

[0091] In some embodiments, the packing element 71 has a mounting groove on the side opposite to the loading assembly 30, and the seal 78 is housed within the mounting groove. In this case, the installation position of the seal 78 is more stable. In other embodiments, the side of the packing element 71 opposite to the loading assembly 30 is flat, and the seal 78 is sandwiched between the packing element 71 and the workpiece 300 to be repaired and deforms. In this case, the sealing effect of the seal 78 is more obvious. The arrangement of the seal 78 makes the fit between the packing element 71 and the workpiece 300 to be repaired tighter, which facilitates subsequent vacuuming and filling, and the repair device 100 can better repair the workpiece 300 to be repaired.

[0092] When the repair device 100 of this application repairs the workpiece 300, the clamping member 333 first rotates to the outside of the limiting space 3311. After the workpiece 300 is loaded into the limiting space 3311 formed by the positioning member 331, the clamping member 333 rotates to the inside of the limiting space 3311 and abuts against the workpiece 300, thus clamping the workpiece 300 onto the loading assembly 30. The second driving assembly drives the second movable plate 315 to move relative to the first movable plate 313 along the second direction L, and the third driving assembly drives the third movable plate 317 to move relative to the second movable plate 315 along the second direction L, so that the cracked area on the workpiece 300 is aligned with the filler member 71 in the first direction H. The heating assembly 50 heats the workpiece 300 to a preset temperature, causing the substrate of the workpiece 300 to expand and the crack size at the crack location to increase. The first drive assembly 20 drives the loading assembly 30 to move in the first direction H, and abuts against the packing member 71 (and the seal 78) to form a sealed packing cavity 711. The barrier 77 is controlled to be in a first position, opening the flow channel 7311, and the vacuum pump 73 evacuates the packing cavity 711 through the first pipe 731, also removing air from the crack. The barrier 77 is controlled to be in a second position, blocking the flow channel 7311. The packing pump 75 applies positive pressure to the second pipe 751 to inject packing into the packing cavity 711 through the second pipe 751. The vacuum environment in the packing cavity 711 and the crack causes the packing to fully fill the crack. The packing pump 75 maintains positive pressure for a preset duration (e.g., 5 seconds) to ensure that the crack in the workpiece 300 being repaired is filled with packing. The first drive assembly 20 drives the loading assembly 30 to move in the first direction H and separates from the packing member 71 (and the seal 78) to break the vacuum within the packing member 71. The stuffing pump 75 applies negative pressure to the second pipe 751 to reverse-pump and pump unused packing material from the stuffing box 71 and residual packing material from the second pipe 751 into the stuffing bin 79 for storage. The clamping member 333 rotates to the outside of the limiting space 3311 and releases its contact with the workpiece 300 to be repaired, thus removing the workpiece 300 from the loading assembly 30. Finally, the residual packing material on the workpiece 300 to be repaired is cleaned, and the cleaned workpiece 300 is cured by ultraviolet irradiation to obtain the finally repaired workpiece.
