Description

Technical Field

[0001] This application relates to the field of riveting dies, and particularly to an opposed synchronous riveting die with a post-riveting detection function. Background Art

[0002] In modern manufacturing, the riveting process is widely used in the assembly of various complex components, especially in situations where high-strength connections are required. In the prior art, side-hung riveting is usually adopted to achieve the fixed connection of products. However, for some products with complex shapes and irregular inner sides, the traditional riveting methods gradually expose their limitations. Specifically, there are many irregular shapes on the inner side of the formed product. These irregular parts, together with the small corners at the bending positions, make it very difficult to position, place, and pick up the product during the riveting process. In addition, since riveting fixation is required in four directions, the traditional riveting method requires riveting in one direction first, and then turning the product or the riveting tool to rivet in another direction. Such frequent operations greatly reduce the production efficiency.

[0003] This traditional riveting method not only increases the complexity of the operation but also leads to low efficiency in the production process. During the operation, workers need to constantly turn the product or the tool for riveting, which is not only time-consuming but also increases the risk of product damage. At the same time, due to the difficulty in positioning the product, it is easy to have offsets or inaccuracies during the riveting process, further affecting the riveting quality and the reliability of the finished product. These problems are particularly obvious in mass production, resulting in difficult improvement of production efficiency and low qualified rate of finished products.

[0004] In addition, to ensure product quality, a visual inspection device is usually used for inspection after riveting. This method requires moving the product from the riveting position to the inspection device and then refixing it, which increases the complexity of the process, is time-consuming and laborious, and reduces the overall production efficiency.

[0005] Specifically, the current post-riveting inspection mainly relies on a visual inspection device to achieve. This method generally includes the following steps:

[0006] Product transfer: After riveting is completed, the product needs to be transferred from the riveting station to the inspection station. This process is usually completed by an automated conveying device or manually by an operator. The transfer of the product requires precise positioning to ensure that it can correctly enter the inspection station.

[0007] Product refixation: After reaching the inspection station, the product needs to be refixed to ensure a stable state during the inspection. Special fixtures or fixing devices are usually used, and the product is fixed through positioning pins or clamping mechanisms to avoid displacement or shaking during inspection.

[0008] Visual Inspection: After being fixed, the product is inspected by a visual inspection system. The inspection system uses a high-precision camera to scan each rivet point one by one and uses image processing technology to analyze the shape, position, and connection status of each rivet point to determine whether it meets quality standards.

[0009] However, this inspection method has its drawbacks. Each transfer and fixturing operation can introduce new variables, increasing errors during the inspection process and thus affecting inspection accuracy. Especially in large-scale production, the time required for transfer and fixturing significantly impacts overall production efficiency, slowing production and increasing operating costs.

[0010] In view of the above-mentioned deficiencies in the existing technology, it is of great significance to develop a synchronous riveting die with a post-riveting detection function. Utility Model Content

[0011] The purpose of this application is to overcome at least one of the shortcomings of the existing technology and provide a synchronous riveting die with a post-riveting detection function. The riveting die performs detection simultaneously during the riveting process, eliminating the steps of product transfer and re-fixing, significantly improving production efficiency and riveting quality, and is particularly suitable for products with complex shapes and irregular inner sides.

[0012] To achieve the above-mentioned purpose, the present application discloses a counter-synchronous riveting die with a post-riveting detection function, comprising a lower die assembly, an upper die assembly opposite to the lower die assembly and matched with a guide mechanism, wherein the lower die assembly comprises a jig for mounting the product to be riveted, and at least one rivet detection assembly located next to the jig. During operation, the rivet detection assembly cooperates with the jig to complete the riveting of the product to be riveted; a plunger is mounted on the upper die assembly, which is aligned with the rivet detection assembly and is used to drive the rivet detection assembly to move; the jig comprises a center block and a slider mounted on the center block, the slider and the center block are connected and matched through an inclined guide rail, and the bottom of the slider is fixed to the center block. A push rod with a spring is installed on the top; the rivet inspection assembly includes a leaning block, a base, a movable block slidably mounted on the base and opposite to the leaning block, a splint mounted in front of the movable block, a stripping plate coordinated with the splint through a spring and a guide rod, and a camera and an illumination light source mounted on the stripping plate; the movable block has a guide inclined surface coordinated with the inserting knife, and a return spring coordinated with the movable block is installed in the base. When the inserting knife moves downward, the movable block is pushed close to the jig via the guide inclined surface; the leaning block is provided with a wear-resistant leaning block coordinated with the inserting knife on the side opposite to the movable block; the movable block is horizontally provided with multiple rivet punches passing through the splint and the stripping plate.

[0013] In some embodiments, the camera is embedded near the upper end of the stripper plate and horizontally opposite to the jig, and the camera is recessed into the surface of the stripper plate to prevent physical contact with the jig and the product to be riveted; a notch is provided on the splint for avoiding the camera, which is used to avoid the camera when the stripper plate and the splint are close to each other.

[0014] In some embodiments, the upper die assembly is further provided with an upper stripper plate that cooperates with the fixture in alignment.

[0015] In some embodiments, corresponding slots are provided on the mating surface of the slider and the riveting punch.

[0016] In some embodiments, in the initial state of the fixture, the slider is lifted by the ejector pin and is higher than the center block; when the fixture is pressed under the action of the upper die assembly, the slider descends and is guided to one side of the center block via the inclined guide rail.

[0017] Compared with the prior art, this riveting die integrates the functions of riveting and detection, can complete the detection synchronously during the riveting process, omits the steps of product transfer and re-fixation, thereby significantly improving the production efficiency.

[0018] The beneficial effects listed above do not exhaust all the advantages. Other potential beneficial effects and detailed technical implementations will be further revealed in the embodiments or other description parts of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] As Figures 1 to 3 As shown, an opposed synchronous riveting die with a post-riveting detection function disclosed in this embodiment includes an upper die assembly 1, a lower die assembly 2, a fixture 3, a center block 4, a slider 5, a riveting and inspection assembly 6, a base 7, a support block 8, a wear-resistant support block 9, a movable block 10, a clamping plate 11, a stripper plate 12, a camera 13, a lighting source 14, a riveting punch 15, and an upper stripper plate 16. This die completes the riveting and post-riveting detection functions of the product to be riveted through the relative cooperation of the upper die assembly 1 and the lower die assembly 2, and is particularly suitable for the production of products with complex shapes or multiple riveting points.

[0028] The upper die assembly 1 and the lower die assembly 2 are relatively matched through a guiding mechanism. The fixture 3 in the lower die assembly 2 is used to stably mount the product to be riveted to ensure the precise positioning of the product during the riveting process. The fixture 3 is composed of a center block 4, and a plurality of sliders 5 are installed on the center block 4. The sliders 5 are connected to the center block 4 through inclined guide rails. A push rod with a spring is provided at the bottom of the slider 5. In the initial state, the push rod jacks up the slider 5 so that it is higher than the surface of the center block 4. When the upper die assembly 1 applies pressure, the slider 5 moves downward along the inclined guide rail towards the center block 4 under the action of the pressure, thereby realizing the tight fit between the fixture 3 and the product to be riveted.

[0029] The riveting and inspection assembly 6 cooperates with the fixture 3 to complete the riveting and inspection functions. The riveting and inspection assembly 6 is composed of a base 7, a support block 8, a movable block 10, a wear-resistant support block 9, a clamping plate 11, a stripper plate 12, a camera 13, and a lighting source 14. The movable block 10 of the riveting and inspection assembly 6 is slidably installed on the base 7 and cooperates with the plug cutter of the upper die assembly 1 through a guiding inclined surface. During the riveting process, the plug cutter moves downward to push the movable block 10 towards the fixture 3, so that the riveting punch 15 extends out of the stripper plate 12 to realize the riveting action.

[0030] After riveting is completed, the upper die assembly 2 of the camera 13 and the illumination light source 14 in the riveting and inspection assembly 6 moves upward. After the jig 3 returns to its initial position, since at this time, the slider 5 has separated from the side of the riveted product and there is a spacing, it is convenient for visual judgment. On this basis, the camera 13 is activated to perform real-time detection of the riveting points. The camera 13 is embedded at the upper end position of the stripper plate 12 and is horizontally opposite to the jig 3. To protect the camera 13, the surface of the camera 13 is recessed into the surface of the stripper plate 12 to prevent it from making physical contact with the jig 3 or the product to be riveted and avoid damage. During the riveting process, a notch for avoiding the camera 13 is provided on the clamping plate 11 to ensure that the work of the camera 13 is not affected when the stripper plate 12 approaches the clamping plate 11.

[0031] The camera 13 performs high-precision scanning on each riveting point and transmits the images to the detection system. The detection system analyzes the shape, position, and connection status of the riveting points through image processing technology. The detection system can immediately determine whether the riveting quality meets the predetermined standards, thereby realizing real-time quality control. During the detection process, the illumination light source 14 provides sufficient light to ensure the brightness of the detection area and make the images captured by the camera 13 clear and error-free.

[0032] The above detection system belongs to the conventional technology in this field and is not the technical key point of this application and should be regarded as the prior art. Therefore, no detailed description will be given.

[0033] In practical applications, for example, in a factory producing automotive parts, this die can significantly improve the efficiency of riveting and detection. Traditional riveting methods usually require moving the product from the riveting station to the detection station for detection and adjustment, which is not only time-consuming and laborious but also increases the complexity of the process. After using this die, riveting and detection can be completed simultaneously at the same station, greatly reducing the need for product movement and repositioning. By comparing the traditional process and the use of this die, it can be seen that this die significantly reduces the operation time and improves the riveting quality of the product, especially in complex parts that require high-strength connections.

[0034] The stripper plate 12 in the riveting and inspection assembly 6 cooperates with the clamping plate 11 through springs and guide rods to ensure that the product is smoothly separated from the jig 3 after riveting and enters the next process. To avoid physical contact between the camera 13 and the jig 3 or the product to be riveted, the camera 13 is embedded in the surface of the stripper plate 12, avoiding direct contact with the product and ensuring the accuracy of detection at the same time.

[0035] The upper die assembly 1 is also provided with an upper stripping plate 16, which is used to cooperate with the fixture 3 in position after riveting is completed, further ensuring the smoothness and stability of the product when disengaging from the fixture 3. This design reduces the resistance to removing the product from the fixture 3, improving the continuity of the production line. The upper stripping plate 16 is also made of high-strength material to ensure durability and stability during repeated use.

[0036] In terms of materials, the center block 4 and the slider 5 are made of high-strength alloy materials to ensure that they will not deform or be damaged during the high-pressure riveting process. The wear-resistant abutting block 9 is made of wear-resistant steel to increase its service life and durability. The return spring in the riveting and inspection assembly 6 is made of high-elasticity material to ensure that it provides a stable return force, enabling the movable block 10 to return smoothly. The surface coating of the stripping plate 12 uses anti-wear material, further improving the durability of the equipment.

[0037] In other application scenarios, such as in the production line of consumer electronics products, this die can also play great advantages. The production of consumer electronics products requires high precision and high efficiency, and this die can, while maintaining the riveting quality, reduce the pauses and repositioning in production, improving the overall production efficiency. Compared with the traditional process, the use of this die has improved the automation level of the production line and can better adapt to the production requirements of small batches and multiple varieties.

[0038] Through the detailed description of this embodiment, it can be seen that this opposed synchronous riveting die fully considers the balance between production efficiency and riveting quality in design. Especially by integrating the riveting and inspection functions into one operation step, the automation level of the production line has been greatly improved. This die is applicable to products of various complex shapes, especially in the case where multi-rivet-point high-strength connections are required, which can significantly improve production efficiency, reduce production costs, and ensure the high quality of the finished products at the same time.

[0039] Although the exemplary embodiments of the present disclosure have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without substantially departing from the spirit and scope of the present disclosure. Therefore, all changes and modifications are included within the protection scope of the present disclosure defined by the claims. The present disclosure is defined by the appended claims, and equivalents of these claims are also included.
