Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to a repair method and repair device. Background Technology

[0002] Currently, server motherboards are developing towards higher integration and higher performance, and typically contain a large number of electronic components. Server motherboard manufacturing primarily uses PTH (Plated Through Hole) to mount electronic components, while some components are mounted on the PCB (Printed Circuit Board) using SMT (Surface Mount Technology).

[0003] For electronic components installed using the PTH (Pack-Up Toggle) method, when the bottom surfaces of the components are not coplanar, after soldering the components into the corresponding through-holes on the PCB, problems such as tilting, floating, or misalignment can easily occur. This can lead to poor soldering, uneven stress, and PCB damage. Because these components are typically large and have many pins, once an installation error occurs, it is often difficult to repair, and in severe cases, it can even lead to the scrapping of the entire board.

[0004] In related technologies, the problem of non-coplanar bottoms of plug-in components is often identified by manual visual inspection or post-installation testing, and then handled by rework or component replacement. This not only makes it difficult to detect the problem in a timely manner, but also results in high rework costs, affecting board production efficiency and product yield. Summary of the Invention

[0005] This application provides a repair method to at least solve the rework problem caused by the non-coplanar bottom of plug-in components in the related art.

[0006] This application provides a repair method, including: Establish a component information database that includes data information of the target components; Before inserting the target component, obtain the first image information of the support area on the bottom surface of the target component, excluding the pin positions, based on the data information of the target component; Based on the first image information, determine whether there is a non-coplanar region in the support area of ​​the target component. If yes, proceed to the next step; otherwise, proceed with normal production. Determine whether the non-coplanar region affects the stability of the bottom surface of the target component. If so, repair the non-coplanar region; otherwise, proceed with normal production.

[0007] This application also provides a repair apparatus for implementing any of the repair methods described above, the repair apparatus comprising: The information database module is used to store data information of the target components; The scanning module is used to scan the support area on the bottom surface of the target component, excluding the pin positions, and acquire the first image information; Repair module; The control module, the scanning module, the information database module, and the repair module are all connected to the control module. The control module is used to determine whether there is a non-coplanar region in the support area of ​​the target component based on the first image information, and when the non-coplanar region exists and the non-coplanar region affects the stability of the bottom surface of the target component, the control module controls the repair module to repair the non-coplanar region.

[0008] This application utilizes a method where the bottom surface of the target component is scanned before insertion to obtain first image information of the support area (excluding pins). Based on this first image information, it determines whether the support area of ​​the target component is non-coplanar. If non-coplanarity is found, it further determines whether this non-coplanar area affects the stability of the bottom surface of the target component. If so, the non-coplanar area is repaired; otherwise, normal production continues. Therefore, this method solves the technical problem of rework caused by non-coplanar bottoms of inserted components, achieving automatic identification of non-coplanarity, avoiding poor soldering due to non-coplanarity, reducing cost losses from rework or scrap, and simultaneously improving production efficiency, reducing production costs, and enhancing quality.

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0031] It should be noted that, in the description of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. The terms "first," "second," etc., in this application are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0032] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] The repair method provided in this application is mainly applied to an automated plug-in production line environment. This automated plug-in production line includes feeding and conveying equipment, scanning and detection equipment, data analysis equipment, automatic repair equipment, automatic plug-in equipment, and a production management server. The various devices are connected through industrial Ethernet or bus communication to form a complete automated repair and prevention architecture.

[0034] The feeding and conveying equipment is used to transport the target components to be produced to the scanning and inspection area. The feeding and conveying equipment can be a belt conveyor, a pallet conveyor, or a robotic arm handling mechanism, used to transfer the target components between different workstations. The scanning and inspection equipment is set in front of the automatic insertion equipment and is used to inspect the bottom surface of the target components before they are formally inserted into the PCB (Printed Circuit Board). The scanning and inspection equipment includes a bottom scanning component, a side scanning component, an image acquisition component, and a height detection component. The bottom scanning component is used to scan the support area of ​​the bottom surface of the target component. The side scanning component is used to acquire the contour information of the side area of ​​the target component. The image acquisition component is used to acquire the first image information of the bottom surface of the target component. The height detection component is used to detect the height of different areas on the bottom of the target component. The data analysis equipment is connected to the scanning and inspection equipment to analyze the scanning results; the automatic repair equipment is located behind the scanning and inspection equipment to automatically repair non-coplanar areas with stability risks; the automatic insertion equipment is located behind the repair equipment to insert the target components that have been inspected or repaired into the corresponding positions on the PCB board; the production management server is used to establish a component information database and record the scanning data, repair data, and production result data of different target components.

[0035] Embodiments of this application provide a repair method, including: Step S1: Establish a component information database that includes data information of the target component 01; Step S2: Before inserting the target component 01, obtain the first image information of the support area on the bottom surface of the target component 01, excluding the pin positions, based on the data information of the target component 01. Step S3: Determine whether there is a non-coplanar region 6 in the support area of ​​the target component 01 based on the first image information. If yes, proceed to step S4; otherwise, proceed to normal production. Step S4: Determine whether the non-coplanar region 6 affects the stability of the bottom surface of the target component 01. If yes, repair the non-coplanar region 6; otherwise, proceed with normal production.

[0036] In this embodiment, the component information database is used to store data information of different target components 01. The data information includes structural information, model information, support area size information, and three-dimensional contour information. Before entering the automatic insertion station, the target component 01 first enters the scanning area. The scanning module scans the support area on the bottom surface of the target component 01, excluding the pin positions, based on the three-dimensional contour information of the target component 01, and obtains the first image information corresponding to the support area.

[0037] The support area refers to the region where the target component 01 contacts the PCB board and provides support when mounted on it. Since the pin area of ​​the target component 01 is used for insertion into PCB vias, it is not analyzed as a stable support area.

[0038] During the scanning process, height data at different locations on the bottom of the target component 01 can be acquired through height scanning, forming a height distribution image corresponding to the support area. The system then analyzes the first image information to determine whether there is a non-coplanar region 6. For example, when there is a significant height difference between a local location of the support area and the surrounding area, it is determined that a non-coplanar region 6 exists in that area.

[0039] If there is no non-coplanar region 6, it means that the bottom of the target component 01 is flat and can be stably supported on the PCB board surface. Therefore, the target component 01 is allowed to continue to enter the automatic insertion station and carry out normal production.

[0040] If a non-coplanar region 6 exists, the system further determines whether this non-coplanar region 6 affects the stability of the bottom surface of the target component 01. For example, when the non-coplanar region 6 is located in the middle of the support area and has a small area, although there are local voids or protrusions forming the non-coplanar region 6, it will not affect the overall stress stability of the target component 01, so no repair is needed; however, when the non-coplanar region 6 is located at the edge or has a large area, it may cause the target component 01 to tilt, float, or fall over after insertion, so repair is required.

[0041] When the system determines that repair is needed, it automatically repairs the non-coplanar area 6. After the repair is completed, the target component 01 re-enters the scanning area for re-inspection. When the re-inspection result meets the stability requirements, it enters the automatic insertion station.

[0042] By employing the above methods, this embodiment can identify bottom non-coplanarity issues before the target component 01 is formally soldered, avoiding the problems of tilting, floating, or leaning that are only discovered after soldering in traditional solutions. At the same time, by completing repairs before component insertion, it can also reduce rework operations, lower the risk of PCB board damage, and improve the overall production yield and efficiency of server boards.

[0043] Based on the above embodiments, step S4 includes: Step S41: Determine whether there is a connected region in the non-coplanar region 6 that is connected to the edge 8 of the side of the target component 01. If yes, proceed to step S42; otherwise, proceed to step S43. Step S42: Determine whether the connected region includes two intersecting edges 8, and whether the two intersecting edges 8 belong to two adjacent sides. If yes, obtain the second image information of the sides where the two intersecting edges 8 are located in the target component 01 according to the data information of the target component 01, and perform the filling step and double edge repair step according to the first image information and the second image information. If no, determine whether the total area of ​​the non-coplanar region 6 is greater than 2% of the total area of ​​the support region. If yes, obtain the third image information of the sides connected to the non-coplanar region 6 according to the data information of the target component 01, and perform the filling step and single edge repair step according to the first image information and the third image information. If no, proceed with normal production. Step S43: Determine whether the total area of ​​the non-coplanar regions 6 is greater than 10% of the total area of ​​the supporting regions and / or the area of ​​a single non-coplanar region 6 is greater than 5% of the total area of ​​the supporting regions. If yes, then perform the filling step and the edgeless repair step. If no, then proceed with normal production.

[0044] In this embodiment, we first analyze whether the non-coplanar region 6 is connected to the edge 8 on the side of the target component 01. When the non-coplanar region 6 extends to the edge 8 on the side, it indicates that the edge support capability has been affected. At this time, the target component 01 is more likely to tilt. Therefore, further edge classification analysis is required.

[0045] During the actual scanning process, the scanning module scans the two intersecting edges 8 of the target component 01 according to the three-dimensional contour information of the target component 01 to obtain the second image information, and scans the connected sides of the non-coplanar region 6 to obtain the third image information.

[0046] If the connected region includes two intersecting edges 8, and the two edges 8 belong to two adjacent sides respectively, it indicates that the corner support of the target component 01 is missing. At this time, the target component 01 is prone to tilting in the corner direction. Therefore, the filling step and the double edge 8 repair step are performed.

[0047] If the connected region has only one edge 8, or if the connected region has two or more edges 8, but none of the two or more edges 8 intersect and belong to adjacent side faces, then it is necessary to further determine whether the total area of ​​the non-coplanar regions 6 exceeds 2% of the total area of ​​the supporting region. If it exceeds 2%, it indicates that a single edge region may have affected the overall stability, so the filling step and the single edge repair step are performed; if it does not exceed 2%, it indicates that the impact of edge 8 is small, and normal production can continue.

[0048] In the case where there is no edge connectivity, the system continues to determine whether the area of ​​the non-coplanar region 6 meets the edge-free repair condition. When the total area of ​​the non-coplanar region 6 is greater than 10% of the total area of ​​the support region, or the area of ​​a single non-coplanar region 6 is greater than 5% of the total area of ​​the support region, it indicates that although the non-coplanar region 6 does not extend to the edge 8, its internal support capacity is already significantly insufficient. Therefore, the filling step and the edge-free repair step are executed.

[0049] In this specific embodiment, the positional relationship and area size of the non-coplanar regions 6 are classified and judged, avoiding the problem of simply repairing them uniformly based on the existence of non-coplanar regions 6 in the traditional solution. This can effectively improve the accuracy of repair and reduce unnecessary repair operations.

[0050] In one specific embodiment, the above filling step includes: Step S01: Extend the repair piece 5 from the opening of the non-coplanar region 6 to the bottom surface of the non-coplanar region 6, so that the repair piece 5 fits against the bottom surface of the non-coplanar region 6; and the distance between the edge of the repair piece 5 and the edge of the non-coplanar region 6 is smaller than the size of a single repair piece 5. Step S02: Determine whether the distance between the side of the repair part 5 away from the bottom surface of the non-coplanar region 6 and the opening of the non-coplanar region 6 is greater than the thickness of a single repair part 5. If yes, proceed to the next step; otherwise, end the filling process.

[0051] Step S03: Extend the repair piece 5 from the top of the opening of the non-coplanar region 6 to the bottom surface of the repair piece 5 closest to the opening along the depth direction in the non-coplanar region 6, and the distance between the edge of the repair piece 5 and the edge of the non-coplanar region 6 is smaller than the size of a single repair piece 5, and return to step S02.

[0052] The openings of the non-coplanar region 6 mentioned in this application refer to the openings located on the bottom surface of the target component 01 within the non-coplanar region 6.

[0053] like Figure 7 As shown, the ejector structure 3 in the repair module pushes the repair piece 5 upward from the opening of the non-coplanar region 6, allowing the repair piece 5 to gradually enter the interior of the cavity in the non-coplanar region 6. Since the repair piece 5 itself has a certain thickness, when the depth of the cavity in the non-coplanar region 6 is large, a single layer of repair piece 5 cannot completely fill the cavity. In this case, a second or more layers of repair piece 5 are added to the cavity. To ensure the repair effect, the spacing between the edge of the repair piece 5 and the edge of the non-coplanar region 6 must be smaller than the size of a single repair piece 5. Repair pieces 5 should be arranged as densely as possible within the cavity area to improve overall support strength. In some cavities of the non-coplanar region 6, it may not be possible to place an integer number of repair pieces 5. Figure 8As shown, theoretically four repair parts 5 are needed, but the actual space can only accommodate three repair parts 5. Therefore, it can be done as follows: Figure 9 As shown, the three repair parts 5 are evenly distributed in the cavity area of ​​the non-coplanar region 6 to improve the overall support uniformity. After each filling, it is necessary to re-determine the distance between the surface of the repair part 5 facing the opening of the non-coplanar region 6 and the opening of the cavity of the non-coplanar region 6. When the distance is less than the thickness of a single repair part 5, it means that the cavity of the non-coplanar region 6 has been basically filled, and the filling is stopped at this time.

[0054] In this specific embodiment, by filling the cavity in the non-coplanar region 6 with the repair component 5, it is possible to adapt to filling cavities in the non-coplanar region 6 with different depths and shapes, thereby improving the support uniformity of the repair area and effectively avoiding local collapse problems.

[0055] The repair component 5 can be set as an elastic structure. The repair component 5 is made of elastic material, such as silicone material, flexible resin material or polymer elastic material. Since the shape of the cavity of the non-coplanar region 6 at the bottom of different target components 01 is different, by setting an elastic structure, the repair component 5 can undergo a certain deformation after being compressed, so as to better fit the internal contour of the non-coplanar region 6.

[0056] In addition, at least one side of the repair component 5 is adhesive, and at least the surface of the repair component 5 that is used to contact the bottom surface of the cavity in the non-coplanar region 6 is adhesive, so that the repair component 5 is stably attached to the bottom of the target component 01 after being inserted into the cavity in the non-coplanar region 6, thus preventing it from falling off during subsequent insertion or wave soldering.

[0057] Furthermore, the single-sided dimension of the repair piece 5 is less than or equal to 2% of the single-sided dimension of the bottom surface of the target component 01. By using a smaller-sized repair piece 5, the adaptability to complex void areas can be improved. For example, for voids in irregularly shaped, non-coplanar regions 6, the smaller-sized repair pieces 5 can be arranged more flexibly. The repair piece 5 can also be set as a circle, and the radial dimension of the circle can be set to multiple sizes such as 0.1mm, 0.2mm, 0.5mm, and 1mm, which further enhances its adaptability.

[0058] This specific embodiment improves the adhesion and stability between the repair component 5 and the void in the non-coplanar region 6 by setting at least one side of the repair component 5 to be adhesive and the repair component 5 to be an elastic component, thereby improving the reliability of the repair.

[0059] In one specific embodiment, the support area of ​​the target component 01 has multiple non-coplanar regions 6. The filling step includes filling the non-coplanar regions 6 sequentially in descending order of the size of the opening of each non-coplanar region 6. After filling one non-coplanar region 6, the total area of ​​the remaining non-coplanar regions 6 is obtained, and it is determined whether the total area of ​​the remaining non-coplanar regions 6 is less than 5% of the total area of ​​the support area. If so, the filling is stopped; if not, the filling continues.

[0060] like Figure 7 As shown, the support area of ​​the target component 01 has multiple non-coplanar regions 6. The opening area of ​​the first non-coplanar region 1 on the left is smaller than the opening area of ​​the second non-coplanar region 2 on the right. The second non-coplanar region 2 with the larger opening can be repaired first. After the second non-coplanar region 2 is repaired, it is determined whether the opening area of ​​the remaining first non-coplanar region 1 is less than 5% of the total area of ​​the support area. If so, no filling repair is needed; otherwise, the first non-coplanar region 1 is filled and repaired. The cavity in the first non-coplanar region 1 on the left is shallow, and filling with one repair piece 5 is sufficient. The cavity in the second non-coplanar region 2 is deep, requiring two repair pieces 5 to be filled. When the opening size of the non-coplanar region 6 is smaller than the size of the repair piece 5, preventing the repair piece 5 from being smoothly inserted into the cavity of the non-coplanar region 6, the filling repair of the non-coplanar region 6 can be cancelled, or a smaller repair piece 5 can be used for filling. Figure 8 , Figure 9 As shown, when the opening size of the non-coplanar region 6 is large, multiple repair pieces 5 can be filled. When filling the first layer, N repair pieces 5 can be filled while leaving gaps. However, the remaining gaps cannot completely fill an independent repair piece 5. At this time, N repair pieces 5 can be evenly arranged in the non-coplanar region 6, where N is a positive integer greater than zero.

[0061] In this specific embodiment, when the support area of ​​the target component 01 has multiple non-coplanar regions 6, the non-coplanar regions 6 with larger opening areas are filled first, and the filling is stopped when the total area of ​​the remaining non-coplanar regions 6 is less than 5% of the total area of ​​the support area. Since the total area of ​​the remaining non-coplanar regions 6 is small, it will not affect the stability of the bottom surface of the target component 01. Therefore, while ensuring the filling effect, the workload of the filling steps can be reduced and the filling efficiency can be improved.

[0062] In one specific embodiment, the edgeless repair step includes: Step SA01: Place the first cover plate 4 on the opening of the non-coplanar region 6, and the first cover plate 4 completely covers the opening of the non-coplanar region 6.

[0063] In this embodiment, when the non-coplanar region 6 is not connected to the edge 8, after completing the filling step, the system further uses the first cover plate 4 to cover the opening of the non-coplanar region 6.

[0064] In the specific cutting process, such as Figure 10 As shown, the system first generates a circular region tangent to the outer contour of the non-coplanar region 6, and then adds a preset compensation size, such as 0.05mm or 0.1mm, to the circle to form the actual cutting size of the first cover plate 4.

[0065] like Figure 12 As shown, the first cover plate 4 can be lifted from bottom to top by the ejector pin structure 3 and attached to the bottom of the target component 01, thereby achieving complete coverage of the opening of the non-coplanar region 6. Figure 11 As shown, on a single large bottom cover plate, the size of the first cover plate 4 is calculated based on the size of the opening in the non-coplanar region 6, and then it is cut.

[0066] By setting the first cover plate 4, this embodiment can further improve the overall flatness of the cavity area and prevent the internal repair parts 5 from shifting during subsequent production.

[0067] In one specific embodiment, the single-edge repair step includes: Step SB01: Place the second cover plate 9 on the first connecting area 7. The first connecting area 7 is the area where the non-coplanar area 6 connects with the side and edge 8 of the target component 01. The second cover plate 9 completely covers the first connecting area 7 and is completely located within the side connected by the first connecting area 7. It should be noted that in step SB01, when it is necessary to lift the second cover plate 9 through the ejector structure 3, the target component 01 can be rotated by a certain angle before step SB01 so that the side connected by the first connecting area 7 faces the ejector structure 3; when the moving structure that controls the second cover plate 9 to be attached to the first connecting area 7 can be directly attached to the second cover plate 9 from one side of the target component 01, the operation of rotating the target component 01 before step SB01 can be cancelled.

[0068] Step SB02: Place the third cover plate on the opening of the non-coplanar region 6, so that the third cover plate completely covers the opening of the non-coplanar region 6.

[0069] like Figure 13 As shown, the first connected region 7 is the region where the non-coplanar region 6 connects with the side surface and the edge 8 of the side surface of the target component 01. The non-coplanar region 6 penetrates the side surface of the target component 01 and the edge 8 connecting the side surface and the bottom surface.

[0070] In this embodiment, when the non-coplanar region 6 is connected to the edge 8 of a single side, the system first completes the filling step, and the bottom surface of the target component 01 is used for repair. During the repair process, it is prioritized to ensure that the repair part 5 can contact the edge 8 of the side of the hole in the non-coplanar region 6. When the repair part 5 cannot contact the edge 8 of the side of the hole in the coplanar region, the position of the repair part 5 can be adjusted appropriately to make the gap between the repair part 5 and the edge 8 of the side of the hole in the non-coplanar region 6 as small as possible.

[0071] like Figure 15 As shown, the target component 01 can be switched from a horizontal state to a vertical state, so that the corresponding side faces down, and the first connecting area 7 can be covered by the second cover plate 9.

[0072] Since the first connecting area 7 is located in the side region, the second cover plate 9 is completely located within the corresponding side region. After the second cover plate 9 is installed, the system restores the target component 01 to a horizontal state.

[0073] It should be noted that during the cutting process of the second cover plate 9, a circular area tangent to the outer contour of the non-coplanar region 6 can be generated first. Then, a preset compensation size, such as 0.05mm or 0.1mm, is added to this circle to form the actual cutting size of the second cover plate 9. Then, the second cover plate 9 is cut along the outermost edge line of the side surface so that the second cover plate 9, after installation, will not exceed the edge 8 connecting with the first connecting region 7 and the side surface. Similarly, during the cutting process of the third cover plate, a circular area tangent to the outer contour of the non-coplanar region 6 can be generated first. Then, a preset compensation size, such as 0.05mm or 0.1mm, is added to this circle to form the actual cutting size of the third cover plate. Then, the third cover plate is cut along the outermost edge line of the bottom surface so that the third cover plate, after installation, will not exceed the edge of the non-coplanar region 6.

[0074] By using a dual-coverage method on the sides and bottom, this embodiment can enhance the support capability of the edge area, thereby avoiding the problem of unilateral tilting of the target component 01.

[0075] In one specific embodiment, The double-edge repair procedure includes: Step SC01: Cover the second connecting region 12 with the fourth cover plate 11. The second connecting region 12 is the region where the non-coplanar region 6 is connected to one side of the target component 01 and the edge 8 of this side. The fourth cover plate 11 completely covers the second connecting region 12 and is completely located within the side connected by the second connecting region 12. Step SC02: Place the fifth cover plate on the third connecting region 10. The third connecting region 10 is the region where the non-coplanar region 6 connects with the other side of the target component 01 and the edge 8 of this side. The fifth cover plate completely covers the third connecting region 10 and is completely located within the side connected by the third connecting region 10. Step SC03: Place the sixth cover plate on the opening of the non-coplanar region 6, so that the sixth cover plate completely covers the opening of the non-coplanar region 6.

[0076] In this embodiment, when the non-coplanar region 6 is detected to be connected to the edges 8 of two adjacent sides simultaneously, it indicates that the corner region of the target component 01 has significant support deficiency. Since the target component 01 is usually transported by a nozzle during the automatic insertion process and is subjected to combined forces in the vertical and horizontal directions during insertion, the presence of a void structure in the non-coplanar region 6 in the corner region can easily cause the target component 01 to shift its posture during insertion.

[0077] First, based on the scanning results, the spatial ranges of the second connected region 12 and the third connected region 10 are determined. A filling step is then performed, allowing the repair component 5 to enter the interior of the non-coplanar region 6 and extend along the two edges 8 to form an initial support structure. After filling, the target component 01 is switched so that the side connected to the second connected region 12 faces downwards. Then, the fourth cover plate 11 is installed into the second connected region 12. After the fourth cover plate 11 covers the corresponding edge 8 area, the orientation of the target component 01 is further adjusted so that the side connected to the third connected region 10 faces downwards, and the fifth cover plate is installed into the third connected region 10.

[0078] It should be noted that, in this specific embodiment, when installing the fourth cover plate 11 to the second connecting area 12, the target component 01 may not be switched to face downwards on the side connected to the second connecting area 12, and the fourth cover plate 11 may be directly installed to the second connecting area 12 from the side; when installing the fifth cover plate to the third connecting area 10, the target component 01 may not be switched to face downwards on the side connected to the third connecting area 10, and the fifth cover plate may be directly installed to the third connecting area 10 from the side.

[0079] After completing the repairs on both sides, the sixth cover plate is installed at the opening of the non-coplanar region 6 at the bottom of the target component 01. The sixth cover plate not only covers the non-coplanar region 6 at the bottom, but also forms an overlapping structure with the fourth cover plate 11 and the fifth cover plate, thereby forming an overall closed repair structure.

[0080] In this application, the first cover plate 4, the second cover plate 9, the third cover plate, the fourth cover plate 11, the fifth cover plate, and the sixth cover plate can all adopt a flexible sheet structure, and the surfaces of the first cover plate 4, the second cover plate 9, the third cover plate, the fourth cover plate 11, the fifth cover plate, and the sixth cover plate are provided with an adhesive layer, which can stably adhere to the bottom or side of the target component 01. In order to avoid the first cover plate 4 from affecting the stability of the bottom surface of the target component 01, the thickness of the first cover plate 4, the third cover plate, and the sixth cover plate can be less than or equal to 0.2 mm. In addition, during the installation process, the first cover plate 4, the second cover plate 9, the third cover plate, the fourth cover plate 11, the fifth cover plate, and the sixth cover plate in this application can have grooves less than or equal to their thickness machined on their corresponding mounting surfaces. The first cover plate 4, the second cover plate 9, the third cover plate, the fourth cover plate 11, the fifth cover plate, and the sixth cover plate can be installed into the corresponding grooves to avoid the first cover plate 4, the second cover plate 9, the third cover plate, the fourth cover plate 11, the fifth cover plate, and the sixth cover plate being too thick and affecting the stability of the bottom surface of the target component 01.

[0081] The edge of the sixth cover plate can extend further to the corner position and cover part of the edge area of ​​the fourth cover plate 11 and the fifth cover plate to improve the overall connection strength.

[0082] During the cutting process of the fourth cover plate 11 and the fifth cover plate, a circular area tangent to the outer contour of the non-coplanar region 6 can first be generated. Then, a preset compensation size, such as 0.05mm or 0.1mm, is added to this circle to form the actual cutting size of the fourth cover plate 11 and the fifth cover plate; then... Figure 18 , Figure 19 As shown, the fourth cover plate 11 is cut along the outermost edge line of the side surface, ensuring that the fourth cover plate 11, after installation, does not exceed the edge 8 and side surface that connects with the second connecting area 12. The fifth cover plate is cut in the same way as the fourth cover plate 11, ensuring that the fifth cover plate, after installation, does not exceed the edge 8 and side surface that connects with the third connecting area 10. During the cutting process of the sixth cover plate, a circular area tangent to the outer contour of the non-coplanar region 6 is first generated based on the outer contour of the non-coplanar region 6. Then, a preset compensation dimension, such as 0.05mm or 0.1mm, is added to this circle to form the actual cutting size of the sixth cover plate. Finally, the sixth cover plate is cut along the outermost edge line of the bottom surface, ensuring that the sixth cover plate, after installation, does not exceed the edge of the non-coplanar region 6.

[0083] This specific embodiment repairs two adjacent edges 8 in different directions, thereby simultaneously restoring the edge support capacity of the target component 01 in two directions. This effectively reduces the risk of corner suspension of the target component 01 and improves the overall stability of the target component 01. In addition, the closed-loop covering structure formed by the fourth cover plate 11, the fifth cover plate, and the sixth cover plate effectively restricts the displacement of the internal repair component 5, preventing the repair component 5 from falling off during transportation vibration, plug-in collision, or welding thermal shock. Through the automated double-edge 8 repair process, the positional deviation problem that exists in the manual repair process can be reduced, improving the consistency of mass production and the standardization of repair.

[0084] In one specific embodiment, step S42 includes either the following steps after performing the filling step and the double-edge repair step, or after performing the filling step and the edgeless repair step: Step S421: Send the first scan problem handling task to the production management terminal and the supplier; Step S422: Modify the corresponding information of the target component 01 in the information database according to the repaired data.

[0085] In this embodiment, after completing double-edge repair or edgeless repair, a first scanning problem processing task is automatically generated. The first scanning problem processing task includes the model, batch number, supplier information, image of non-coplanar region 6, area of ​​non-coplanar region 6, connectivity of edge 8, repair method, repair parameters, number of repairs, and repair results of the target component 01. Then, the first scanning problem processing task is sent to the production management end and the supplier so that the production management end can grasp the current production risks in a timely manner, and the supplier can optimize the production process based on the defect data. At the same time, the information database can also be updated according to the repaired scanning results.

[0086] This specific embodiment, by establishing a first scanning problem handling task, enables the full-process recording and traceability of the non-coplanarity problem of the target component 01, thereby improving production quality management capabilities; by sending the first scanning problem handling task to the supplier, the supplier can be prompted to optimize the processing technology in a timely manner, reducing the probability of non-coplanarity problems from the source; by updating the information database in real time, a defect database corresponding to different target components 01 is formed, providing a data foundation for subsequent risk analysis and process optimization.

[0087] Following step S43, the following is included: Step S431: Send the second scan problem handling task to the production management end and the supplier. The second scan problem handling task is for the target component 01 that has a non-coplanar region 6 and does not need to be repaired.

[0088] In this embodiment, for some target components 01 that have non-coplanar regions 6 but do not affect stability, although the system allows normal production to continue, after detecting the non-coplanar regions 6, it first determines that the current target component 01 does not need to undergo repair steps based on the area ratio, positional relationship, and stability analysis results. Subsequently, a second scanning problem handling task is automatically generated. The second scanning problem handling task may include information such as the target component 01 model, batch information, area of ​​the non-coplanar region 6, location of the non-coplanar region 6, detection time, risk level, and corresponding scan image. The second scanning problem handling task is sent to the production management end and the supplier to continuously track the development trend of minor non-coplanar problems.

[0089] This specific embodiment forms a second scanning problem processing task for minor non-coplanar issues that do not require repair. This avoids the management defects of ignoring problems if they are not repaired in traditional solutions. By continuously recording data on minor non-coplanar issues, it can help enterprises identify potential process fluctuation risks in advance and improve their quality early warning capabilities.

[0090] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.

[0091] An embodiment of this application also provides a repair device for implementing the above-described repair method. The repair device includes an information database module, a scanning module, a repair module, and a control module. The scanning module, the information database module, and the repair module are all connected to the control module. The information database module is used to store data information of the target component 01. The scanning module is used to acquire first image information of the support area of ​​the bottom surface of the target component 01, excluding the pin positions, before the target component 01 is inserted. The control module is used to determine whether there is a non-coplanar region 6 in the support area of ​​the target component 01 based on the first image information, and when there is a non-coplanar region 6 and the non-coplanar region 6 affects the stability of the bottom surface of the target component 01, the control module is used to repair the non-coplanar region 6.

[0092] In this specific embodiment, by setting a control module to uniformly coordinate the scanning module, information database module, and repair module, automated repair can be achieved, improving the overall level of production automation. By having the control module automatically determine the non-coplanar regions 6 and stability risks based on the first image information, the accuracy of defect identification can be improved, and the error of manual judgment can be reduced.
