Description

Technical Field

[0001] The present application relates to the field of metal stamping processing, and in particular to a fool-proof automatic riveting device and a fool-proof identification processing method. Background Art

[0002] In the field of automotive electronic product processing, the riveting and stamping processes of metal plates, tubes, rods, or profiles have always been key research directions. With the rapid development of the automotive industry, higher requirements have been placed on the processing accuracy and production efficiency of automotive electronic products. Many key components in automotive electronic products rely on precise and reliable riveting processes. From the vehicle's control module to the safety system, high-quality riveting operations not only directly affect the performance and stability of automotive electronic products, but also affect the overall quality and safety of the vehicle. It also plays a key role in the smooth operation of the entire automotive production process and is of great significance to the development of intelligent and electrified vehicles. In the existing riveting process of related automotive electronic products, in order to rivet components such as "U"-shaped blades to the substrate, manual operation is mainly relied on. Specifically, the "U"-shaped blade is formed by the top plate and the side plates on both sides of the top plate. The operator needs to first place several "U"-shaped blades of different lengths and shapes one by one on one of the surfaces of the substrate with the "U" opening facing away from the substrate. Since the top plate and the substrate of the "U"-shaped blade are pre-equipped with corresponding rivet bumps and rivet grooves, the top plate position of the blade is then riveted to the substrate through a stamping mechanism. After the riveting of the blades on one surface is completed, the substrate is turned over and the blades are riveted to the other surface in the same way, so that blades are riveted on both sides of the substrate. In the stamping process, the punch press is manually operated for riveting, and different punching heads are replaced to achieve stamping and riveting according to the different conditions of the blades to be riveted on both sides of the substrate. However, the existing method has obvious defects in actual use. On the one hand, because each blade varies in size and shape, and when the blades are densely arranged on the substrate, manual placement of the blades is prone to errors or omissions, which are difficult to detect. This significantly increases the defective rate of stamping and riveting, and subsequent screening of defective products requires secondary rework, significantly reducing processing efficiency. On the other hand, for some high-end automotive electronic products, high processing precision is required, and existing methods rely on manual experience. Blades are prone to shifting during the riveting process, reducing the processing precision of the product, resulting in uneven product quality, and subsequent product testing, which in turn affects the processing efficiency and quality of the product. Summary of the Invention

[0003] In order to ensure that the processing accuracy and efficiency of the blades and substrates can be improved, and to be able to monitor in real time whether there are any problems with incorrect placement or omission of the blades, and to automatically complete the riveting after the blades are placed correctly, the present application provides a fool-proof automatic riveting device and a fool-proof identification processing method.

[0004] In the first aspect, the present application provides a fool-proof automatic riveting device, including a jig, an image control module and a punch execution system, the jig includes a base plate, a carrier plate and a buffer assembly, the base plate and the carrier plate are connected by the buffer assembly, and the two plate surfaces are relative to each other to form a cavity structure, the carrier plate is provided with a plurality of placement beams at intervals, each of the placement beams is provided with an avoidance gap on both sides, and the two side plates of the blade are respectively provided with the avoidance gap so that the inner wall of the top plate of the blade is tightly attached to the surface of the placement beam, each of the placement beams is provided with color marking points of different colors at intervals along the length direction, and each of the two ends of the placement beam along the length direction is provided with its own width marking point; the image control module includes an image acquisition module, an image processing module and a control module; the image acquisition module is used to obtain the positioning image of all blades on the carrier plate in real time; the image processing module is used to determine whether the length of the blade matches the length of the storage beam by identifying the occlusion status of the color mark point, and to determine whether the coverage area of ​​the blade covering the storage beam at each width mark point is qualified by pre-set coverage area threshold; the control module is electrically connected to the image processing module and the punch execution system, and when the blade exists and the coverage area meets the preset conditions, the control module controls the punch execution system to perform the riveting action. By adopting the above technical solution, the bottom plate of the jig and the carrier plate are connected by a buffer component to form a cavity structure, which can play a buffering role during the riveting process, reduce the damage to the equipment and workpiece caused by the impact force, and extend the service life of the equipment. The storage beams arranged at intervals on the carrier plate and the avoidance gaps on both sides allow the two side plates of the blade to pass through them, so that the inner wall of the blade top plate is close to the surface of the storage beam, ensuring the stability and accuracy of the blade placement.Each storage beam is provided with color marking points of different colors at intervals along the length direction and width marking points at both ends. The image acquisition module of the image control module obtains the positioning images of all the blades on the carrier plate in real time, and judges whether the coverage area of ​​the blade covering the storage beam at each width marking point is qualified by the preset coverage area threshold. If the coverage area is not within the preset range, it means that the blade is not placed, or the blade placement may be offset or the blade of other length dimensions is placed incorrectly. Since the avoidance gap and the size of the storage beam are pre-set, the size of the avoidance gap is designed based on the thickness that can just accommodate a blade, and the thickness of the blade is consistent. A blade that is too wide cannot pass through the avoidance gap, and a blade that is too narrow cannot be placed. The same storage beam can only hold blades of the same width but different lengths. Therefore, the design of the width marking point is mainly to detect whether the coverage area of ​​the width marking points at both ends of the storage beam can be qualified at the same time. If it is unqualified, it means that the blade is not placed, the blade is slightly offset, or the blade length is too short to cover the storage at the same time. Width marking points at both ends of the beam; at the same time, the image processing module can determine whether the length of the blade matches the placement beam by identifying the occlusion status of the color marking point. If the color marking point is not completely blocked, it means that the blade is not placed or the blade length may not match. For example, as long as the color marking point is not blocked a little, it means that the length of the blade is wrong or there may be gaps between multiple leaves spliced ​​together, which causes the color marking point to be not completely blocked. Therefore, the design of the color marking point is mainly to detect that each color marking point on the placement beam can be continuously and completely covered; through comprehensive judgment by the above two methods, only when it is judged that the blade exists and the coverage area meets the preset conditions, the control module controls the punch execution system to perform the riveting action, which can effectively avoid the problems of incorrect placement, omission and displacement of the blade during the riveting process when the blade is placed manually, greatly reducing the defective rate of subsequent stamping and riveting, improving the processing accuracy and quality of the product, reducing the subsequent process of screening defective products and testing products, thereby improving processing efficiency. Preferably, the jig further comprises a support assembly, wherein the support assembly comprises a support plate and a plurality of support columns, wherein the support plate is arranged between the base plate and the supporting plate and is parallel to the base plate and the supporting plate, and a plurality of support columns are arranged on the support plate at intervals corresponding to the position of each storage beam, and the top of each support column abuts the bottom of the storage beam. By adopting the above technical solution, a support assembly is provided in the jig, wherein the support plate is arranged between the base plate and the supporting plate and is parallel thereto, and a plurality of support columns are arranged on the support plate at intervals corresponding to each storage beam, and the top of each support column abuts the bottom of the storage beam. Since the punch execution system will exert a large pressure on the blades and base plate on the supporting plate during the riveting process, if there is no support, the supporting plate, especially the storage beam part, may be deformed due to uneven force or excessive pressure.The support column can provide direct support for the storage beam, dispersing the pressure on the storage beam and reducing the possibility of deformation. Preferably, the jig further includes a stabilizing connector, which is provided on one side of the carrier plate. The support plate and the bottom plate are both fixedly connected to the stabilizing connector. The carrier plate is movably connected to the stabilizing connector and can slide in the vertical direction. By adopting the above technical solution, during the riveting process, the punch execution system applies a punching force to the blade and the substrate to be processed. Since the carrier plate is movably connected to the stabilizing connector, the carrier plate can slide in the vertical direction to a certain extent. This sliding can buffer and disperse the impact force generated during the punching. On the one hand, it avoids excessive impact force from directly acting on other parts of the jig, prevents the jig from being damaged due to uneven force, and extends the service life of the jig; on the other hand, it allows the blade and the substrate to be processed to fit better during the riveting process, reducing problems such as blade deviation or substrate deformation caused by impact force, thereby improving the accuracy and stability of riveting, reducing the rate of defective products, and thus improving the processing efficiency and quality of the product.

[0005] Preferably, the image acquisition module includes at least one camera, which is positioned above the carrier plate and electrically connected to the image processing module. By adopting the above technical solution, the camera is positioned above the carrier plate, enabling it to capture images of the blades on the carrier plate from a suitable viewing angle. Since the camera is electrically connected to the image processing module, the captured blade positioning images can be promptly transmitted to the image processing module. Based on these positioning images, the image processing module analyzes the blade coverage area at the width markers and the blade obstruction status at the color markers, thereby accurately determining whether a blade exists, whether the blade length matches the mounting beam, and whether the blade coverage area of ​​the mounting beam at each width marker is satisfactory. Preferably, the carrier plate is provided with an auxiliary positioning assembly comprising at least two positioning posts, each of which extends through a predetermined positioning hole in the substrate to be processed. By adopting the above technical solution, the auxiliary positioning assembly is provided on the carrier plate, comprising at least two positioning posts, each of which extends through a positioning hole in the substrate to be processed. This achieves further positioning of the substrate to be processed. This positioning method is not only simple and effective, but also quickly secures the substrate in the correct position, reducing the time and difficulty of manual adjustment, significantly improving production efficiency. Preferably, each positioning post is provided with a pressure sensor on one side. When the substrate to be processed is placed on the positioning post and is in a horizontal position, the pressure sensor detects a pressure signal and transmits the pressure signal to the control module. By adopting the above technical solution, when the substrate to be processed is placed on the surface of the blade and presses horizontally against the two pressure sensors, the two pressure sensors simultaneously detect the pressure change and generate a pressure signal. Because the substrate to be processed only generates pressure when it contacts the pressure sensors when it is accurately placed on the positioning post, the simultaneous detection of the pressure signal by both pressure sensors indicates that the substrate to be processed is horizontally placed in the correct position. The pressure sensors transmit the pressure signal to the control module. If one of the pressure sensors fails to detect a pressure signal, it indicates that the substrate is not placed flat, and the control module will not activate the control of the punch press execution system. This avoids the errors and omissions that may occur when manually judging the substrate placement, effectively improves the accuracy of the riveting operation, ensures that the riveting process is carried out under the premise of accurate substrate placement, thereby improving the processing precision and quality of the product, reducing the number of defective riveted products caused by improper substrate placement, and improving processing efficiency and the overall quality stability of the product.In a second aspect, a foolproof identification processing method for a foolproof automatic riveting device includes the following steps: S1. Manually placing a plurality of blades one by one on a support beam with their openings facing downward; S2. Obtaining a positioning image of the blades on the support plate using the image acquisition module; S3. The image processing module determining whether the blades exist based on whether the blade coverage area at the width marker point in the positioning image is qualified; S4. When determining that a blade exists, the image processing module determines whether the blade coverage area at each width marker point on the support beam is qualified based on the blade occlusion status of the color marker points in the positioning image and a preset coverage area threshold, thereby determining whether the coverage area of ​​the blades at both ends of the support plate covering a preset reference structure meets a preset condition; S5. If the preset condition is met, manually placing the substrate to be processed on the surface of the plurality of blades, and then the control module controlling the punch execution system to perform the riveting operation. By adopting the above technical solution, in the foolproof identification processing method, the plurality of blades are first manually placed one by one on the support beam with their openings facing downward, providing the basis for blade placement. Then, the image acquisition module obtains a positioning image of the blades on the support plate. When determining the presence of a blade, the image processing module further determines whether the blade's coverage area at each width marker point meets preset requirements based on the blade's occlusion status at the color marker points in the positioning image and a preset coverage area threshold. This is used to determine whether the blade's coverage area at each end of the support plate meets preset requirements for the predetermined reference structure. Because each support beam is spaced along its length with color markers of different colors, if the color marker points are correctly occluded, the blade length matches; if the blade coverage area at each width marker point meets the requirements, the blade width matches and the placement is accurate. This ensures precise determination of blade placement and prevents incorrect blade placement. If the preset requirements are met, the substrate to be processed is manually placed on the surface of the blades. The control module then controls the punch press execution system to perform the riveting operation, achieving an automated and accurate riveting process. This avoids the problems of manual blade placement, which can easily lead to incorrect placement or omission of blades, significantly reducing the defective rate of stamping and riveting, improving processing efficiency, and also preventing blade offset during the riveting process due to manual experience, thereby improving product processing precision and quality. Preferably, in step S5, the control module can determine whether the substrate is correctly placed by detecting a pressure signal received by the pressure sensor. If the substrate is correctly placed, the control module controls the punch press execution system to perform the riveting operation. By adopting the above technical solution, in the foolproof identification processing method of the foolproof automatic riveting device, a pressure sensor is provided on the surface of the positioning column.When the substrate to be processed is manually placed on the surfaces of several blades, it will abut the upper surface of the positioning post. At this time, the pressure sensor detects the pressure signal. Because the substrate will fully contact the positioning post and generate pressure only when it is accurately placed in the right position, the accurate placement of the substrate can be accurately determined based on whether each pressure sensor receives a pressure signal. Only when the substrate is accurately placed does the control module control the punch execution system to perform the riveting action. This can avoid the defective products caused by riveting when the substrate is not accurately placed, thereby effectively reducing the defective product rate of stamping and riveting, improving the processing accuracy and quality of the product, reducing the subsequent defective product screening and secondary rework processes, and greatly improving processing efficiency.

[0006] In summary, this application includes at least one of the following beneficial technical effects: 1. The jig's load plate and base are connected by a buffer assembly to form a cavity structure. The load plate is interspersed with support beams, and the blade side plates are spaced apart to allow for clearance between the beams. This allows the inner wall of the blade top plate to rest closely against the beams. This structural design provides a stable placement environment for the blades. The buffer assembly also acts as a buffer during the riveting process, reducing the impact of external forces on the blades and minimizing blade displacement during the riveting process, thereby improving product processing accuracy and quality. 2. The image processing module within the image control module identifies the occlusion status of the color markers on the placement beam. Since blades of different lengths block the color markers differently, it can determine whether the blade and placement beam lengths match. Simultaneously, it uses a preset coverage area threshold to determine whether the blade coverage of the placement beam at each width marker is satisfactory. This recognition of color and width markers allows for precise determination of blade placement, avoiding the potential for manual misplacement or omission of blades, which can be difficult to detect. This reduces the defective rate of stamping and riveting, and improves processing efficiency. 3. The clamping components and auxiliary positioning components of the fixture can provide a stable support point for the substrate, effectively fix the substrate to be processed, and prevent the substrate from shaking or shifting during the placement process, thereby improving the riveting accuracy of the blade and the substrate, improving the processing accuracy, and thus improving product quality.

DETAILED DESCRIPTION

[0009] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

[0010] Example 1 The embodiment of the present application provides a foolproof automatic riveting device, referring to Figure 1 and Figure 2 , including a jig 1, an image control module 2 and a punch execution system 3. Among them, the jig 1 is used to carry and position the blade 4 and the substrate 5 to be processed, the image control module 2 is used to identify and judge the placement of the blade 4, and the punch execution system 3 is used to perform the riveting action when the conditions are met. The three work together to effectively avoid manual operation errors and improve the accuracy and efficiency of the riveting process.

[0011] Specifically, the fixture 1 of this embodiment is composed of a base plate 11, a supporting plate 12, a buffer assembly 13, a support assembly 14, a stabilizing connector 15, a clamping assembly and an auxiliary positioning assembly 16. The base plate 11 and the supporting plate 12 adopt a rectangular plate structure, and the base plate 11 and the supporting plate 12 are opposite to each other to form a cavity structure that can accommodate the side plate of the blade 4. The four corners of the base plate 11 and the supporting plate 12 are connected by the buffer assembly 13.

[0012] The support plate 12 is provided with a plurality of support beams 121 at intervals. Each support beam 121 has a clearance gap 122 on both sides. The side panels of the blade 4 each have a clearance gap 122 formed therethrough, allowing the inner wall of the top plate of the blade 4 to closely contact the surface of the support beam 121. In this embodiment, the support beams 121 are rectangular parallelepiped and are integrally molded from a plastic material on the support plate 12. Plastic support beams 121 are lightweight and low-cost.

[0013] In particular, each support beam 121 is provided with color marking dots 123 of different colors at intervals along its length. The color marking dots 123 can be implemented as colored cylinders embedded in the support beam 121. The color marking dots 123 facilitate the determination of whether the length of the blade 4 matches that of the support beam 121. Each support beam 121 is provided with width marking dots 124 at each end along its length. The width marking dots 124 assist in determining whether the coverage area of ​​the blade 4 covering the support beam 121 is satisfactory.

[0014] Specifically, the buffer assembly 13 includes a mounting post 131 and an elastic member 132. The elastic member 132 can be a spring. The spring has good elasticity and cushioning properties, can play a role in buffering and shock absorption during the stamping process, and can play a role in protecting the jig 1 and the workpiece. The specific installation steps are as follows: the spring is placed on the mounting post 131, the bottom of the mounting post 131 is connected to the base plate 11, and the top of the mounting post 131 is connected to the bottom of the support plate 12. The top and bottom of the spring respectively abut the lower surface of the support plate 12 and the upper surface of the support plate 141. When the support plate 12 is stamped, the spring can exert good cushioning properties.

[0015] Specifically, the support assembly 14 includes a support plate 141 and a plurality of support columns 142. The support plate 141 is horizontally arranged between the base plate 11 and the load-bearing plate 12, and is parallel to the base plate 11 and the load-bearing plate 12. A plurality of support columns 142 are arranged at intervals on the support plate 141 corresponding to the position of each storage beam 121. Each support column 142 is arranged perpendicular to the support plate 141, and its top is in contact with the bottom of the storage beam 121. The support columns 142 can be metal columns, plastic columns, etc. Metal columns have higher strength and can better support the storage beam 121; plastic columns are lighter and have lower cost. In this embodiment, metal support columns 142 are preferred. The setting of the support assembly 14 can enhance the stability of the storage beam 121 and avoid deformation during the stamping process.

[0016] Specifically, the stabilizing connector 15 includes a connecting plate 151 and a handle 152. The connecting plate 151 is arranged on one side of the base plate 11 and the support plate 141 on the carrier plate 12. The support plate 141 and the base plate 11 are fixedly connected to the connecting plate 151 by bolts. The carrier plate 12 and the stabilizing connector 15 are movably connected by a slider and a slide groove and can slide in the vertical direction. Specifically, the connecting plate 151 is provided with a slide groove, and a slider is extended on one side of the carrier plate 12. The slide groove can provide guidance for the sliding of the carrier plate 12 and ensure its sliding stability. The setting of the connecting plate 151 can make the carrier plate 12 more stable during the stamping process and improve the accuracy of the riveting. A handle 152 is provided on the side of the connecting plate 151 away from the carrier plate 12 to facilitate manual movement of the jig 1.

[0017] Specifically, the auxiliary positioning assembly 16 includes two positioning posts 161 and two pressure sensors 162. Both positioning posts 161 are arranged perpendicular to the carrier plate 12 and penetrate the preset positioning holes of the substrate 5 to be processed. The two positioning posts 161 are symmetrically arranged on the carrier plate 12. In particular, a pressure sensor 162 is provided on one side of each positioning post 161. When the substrate 5 to be processed passes through the positioning post 161, the substrate 5 abuts against the pressure sensor 162 on the upper surface of the carrier plate 12. After the pressure sensor 162 detects a pressure signal, it transmits the pressure signal to the control module via a data line. The control module controls the punch execution system 3 to perform the riveting action.

[0018] Specifically, the image control module 2 includes an image acquisition module 21, an image processing module 22, and a control module 23. The image acquisition module 21 includes at least one camera, which is arranged directly above the carrier plate 12 and is electrically connected to the image processing module 22 via a data cable. The data cable is shielded to reduce signal interference. The camera can be a high-definition industrial camera, an infrared camera, etc. High-definition industrial cameras can provide clear images, which facilitates subsequent processing; infrared cameras can also work normally in low-light environments. In this embodiment, a high-definition industrial camera is preferably used. The image acquisition module 21 is used to obtain the positioning image of all blades 4 on the carrier plate 12 in real time. The image processing module 22 determines whether the length of the blade 4 matches the length of the storage beam 121 by identifying the occlusion status of the color marking point 123, and determines whether the coverage area of ​​the blade 4 covering the storage beam 121 at each width marking point 124 is qualified by using a preset coverage area threshold. The control module 23 is electrically connected to the image processing module 22 and the punch execution system 3 via a data line. When the blade 4 exists and the coverage area meets the preset conditions, the control module 23 controls the punch execution system 3 to perform the riveting action.

[0019] Specifically, the punch execution system 3 of this embodiment includes a punch head 32 and a punch driving member 31. The punch driving member 31 is electrically connected to the control module. The punch head 32 includes a punch plate and a plurality of ejectors. The surface of the punch plate is provided with a plurality of ejectors corresponding to the riveting points of the substrate 5 to be processed. The number of ejectors is equal to the number of riveting points of the substrate 5 to be processed. The punch driving member 31 drives the punch head 32 to press down close to the substrate 5 to be processed. The plurality of ejectors correspond to the riveting points one by one, and as the pressure is pressed down, the riveting groove of the substrate 5 is riveted with the riveting protrusion of the blade 4. Riveting is achieved by pressing. The stamping drive part 31 includes a guide rail, a "U"-shaped mounting frame and a cylinder. The "U"-shaped mounting frame is slidably installed above the jig 1 through the guide rail, and the opening faces the jig 1 below. Both ends of the mounting frame are slidably connected to the guide rail. The cylinder is installed on the "U"-shaped mounting frame, and the punching head 32 is vertically installed directly below the cylinder and connected to the output end of the cylinder. The control module 23 controls the "U"-shaped mounting frame to slide to directly above the jig 1, and then the cylinder drives the punching head 32 to press down to the substrate 5 to complete the riveting of the substrate 5 and the blade 4.

[0020] The implementation principle of this embodiment is as follows: through the rational design of the jig 1, the blade 4 to be processed is accurately supported and positioned using structures such as the support beam 121, the avoidance gap 122, the color marking point 123, and the width marking point 124. The image control module 2 uses the image acquisition module 21 to obtain a positioning image of the blade 4, and the image processing module 22 identifies and determines the placement of the blade 4. The control module 23 controls the punch execution system 3 to perform the riveting action based on the judgment result. The provision of the support assembly 14, the stabilizing connector 15, the clamping assembly, and the auxiliary positioning assembly 16 further improves the stability and positioning accuracy of the jig 1, effectively avoids manual operation errors, improves the accuracy and efficiency of the riveting process, and reduces the defective product rate, which is a significant improvement and upgrade compared to the existing technology.

[0021] Example 2 The foolproof identification processing method provided in the embodiment of the present application includes the following steps: S1 manually places several blades 4 one by one on the placement beam 121 with their openings facing downwards. During the placement process, ensure that the two side plates of the blade 4 are respectively provided with avoidance gaps 122 and that the inner wall of the top plate is in close contact with the surface of the placement beam 121.

[0022] S2 uses the image acquisition module to obtain a positioning image of the blade 4 on the carrier plate 12. The camera in the image acquisition module can adjust the shooting angle and focal length according to actual conditions to obtain a clear and accurate positioning image. Conventional technologies such as autofocus and multi-angle shooting can be used to improve the quality of image acquisition.

[0023] Image processing module S3 22 determines whether leaf 4 exists based on whether the width marker 124 in the positioning image covers an area that meets the requirements. Image processing module 22 can use conventional image recognition algorithms, such as edge detection and template matching, to accurately identify width marker 124 and the area covered by leaf 4. Edge detection algorithms can quickly and accurately detect the edges of leaf 4 and calculate the area covered. Template matching algorithms can determine whether the area covered meets the requirements by comparing it with a preset template.

[0024] S4 When it is determined that the blade 4 exists, the image processing module 22 determines whether the coverage area of ​​the blade 4 covering the storage beam 121 at each width marking point 124 is qualified based on the occlusion status of the color marking point 123 in the positioning image and the preset coverage area threshold, and is used to determine whether the coverage area of ​​the blade 4 covering the preset reference structure at both ends of the supporting plate 12 meets the preset conditions.

[0025] If the preset conditions are met in S5, the substrate 5 to be processed is manually placed on the surfaces of the blades 4, and the control module controls the punch execution system to perform the riveting action.

[0026] The operating principle of this embodiment is to identify and determine the placement of blades 4 through a series of steps. Only when the conditions are met can the base plate 5 be placed and riveted. Image acquisition and processing technology accurately determines whether blade 4 is correctly placed, avoiding manual errors. The use of auxiliary positioning assembly 16 and pressure sensor 162 further improves the accuracy of base plate 5 placement, thereby enhancing the precision and efficiency of the riveting process. Compared with traditional processing methods, this method is more scientific, accurate, and efficient, and effectively improves existing technologies.

[0027] Example 3 Based on Example 2, this embodiment further refines step S5, and step S5 further includes the following steps: S51 After the substrate 5 to be processed is manually placed on the surface of the plurality of blades 4, the control module determines whether the substrate 5 is correctly placed based on whether each pressure sensor 162 receives a pressure signal; S52 When it is determined that the substrate 5 is correctly placed, the control module controls the punch execution system to perform the riveting action.

[0028] The implementation principle of this embodiment is as follows: on the basis of Example 3, the steps for determining whether the substrate 5 is accurately placed are refined, and the pressure signal is detected by the pressure sensor 162 to accurately determine whether the substrate 5 is accurately placed, thereby further improving the accuracy and reliability of the riveting process, avoiding poor riveting caused by inaccurate placement of the substrate 5, and achieving further optimization and improvement compared to the existing technology.

[0029] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
