Description

Technical Field

[0001] This invention relates to the field of parts riveting technology, and more specifically to a riveting device. Background Technology

[0002] In industrial production, riveting is a common connection method. It achieves a secure connection by pressing rivets or other fasteners into the workpiece. With the continuous development of industrial automation and intelligence, the requirements for riveting devices are becoming increasingly stringent, demanding functions such as precise positioning, efficient riveting, and automatic detection. Traditional riveting devices often employ simple mechanical structures, such as rivet pliers and rivet guns, which have shortcomings in terms of positioning, riveting accuracy, and automation.

[0003] In the existing technology, automated riveting devices can realize the automatic riveting and transportation of products. However, since the structure of riveted products is usually quite complex, the placement of connecting strips often requires manual operation and manual visual inspection to check whether the connecting strips are placed. Due to the high production efficiency of automated equipment, manual inspection is often not possible to detect in time whether the connecting strips or product structure are placed in the correct position or meet product standards, thus affecting the production efficiency and product yield of automated riveting devices. Summary of the Invention

[0004] One object of the present invention is to provide a riveting device that solves the technical problem of low product yield in the prior art.

[0005] Another objective of this invention is to further improve the product yield of the riveting device.

[0006] According to the purpose of this invention, a riveting device is provided, comprising:

[0007] Base;

[0008] A positioning mechanism is located on top of the base. The positioning mechanism includes two drive components arranged opposite to each other along a first horizontal direction and a positioning element located between the drive components. The drive components and the positioning element are used to position the side and bottom surfaces of the product, respectively.

[0009] A riveting mechanism is located above the positioning mechanism, the riveting mechanism including a pressing assembly protruding toward the base, the pressing assembly being configured to move in a controlled vertical direction;

[0010] At least one detection element, all of which are disposed on the drive assembly, the detection element being configured to selectively detect the structure of the product and / or the placement of the connecting strip riveted to the product;

[0011] A driving mechanism is connected to the bottom of the base. The driving mechanism is configured to drive the base to move toward the riveting mechanism along a second horizontal direction, so as to move the base and the positioning mechanism to the bottom of the riveting mechanism, so that the crimping assembly is controlled to move down to the target position for riveting the product and the connecting strip. The second horizontal direction is perpendicular to the first horizontal direction.

[0012] Optionally, the detection element is a photodetector.

[0013] Optionally, the driving component further includes:

[0014] cylinder;

[0015] A positioning block is located on the side of the cylinder near the positioning member, and the side of the positioning block near the positioning member is provided with a positioning protrusion.

[0016] Optionally, the top surface of the positioning block is provided with a limiting groove, which is used to limit the connection strip.

[0017] Optionally, the detection element is located near the limiting groove on the positioning block to detect the placement position of the connecting strip.

[0018] Optionally, the positioning block is further provided with a mounting hole extending along the first horizontal direction, and the detection element is disposed in the mounting hole to detect the structure of the product.

[0019] Optionally, the riveting device further includes:

[0020] At least one limiting component is located at one end of the base, the limiting component being configured to limit the base.

[0021] Optionally, the limiting component further includes:

[0022] A limiter, extending along the second horizontal direction, is configured to limit the end face of the base;

[0023] A buffer, parallel to the extending direction of the limiter, is configured such that its end protrudes from the end of the limiter toward the base.

[0024] Optionally, the buffer is a hydraulic buffer.

[0025] Optionally, the drive mechanism further includes:

[0026] At least one slide rail extends along the second horizontal direction;

[0027] At least one slider is provided corresponding to each of the slide rails, and the slider is configured to move along the extension direction of the slide rail.

[0028] This invention achieves initial positioning of the product and connecting strip by sequentially installing the product onto the positioning component and snapping it between two drive components, and placing the connecting strip on top of the product. Then, a detection component checks the placement of the connecting strip and / or the structure of the product. After determining that the product structure meets the requirements and / or the connecting strip is correctly placed, the drive mechanism drives the base to move the product towards the riveting mechanism. Once the product reaches the bottom of the riveting mechanism, the pressing component is controlled to move downwards to the target position for riveting the product and connecting strip. This improves the production efficiency of the riveting device while increasing the product yield, preventing low product yield due to non-standard product structure or failure to insert the connecting strip during riveting.

[0029] Furthermore, a positioning element is provided between the two drive components of the present invention. Each drive component has a positioning block on the side near the positioning element, and each positioning block has a positioning protrusion corresponding to the product. When the cylinder drives the positioning block to move toward the product, the positioning protrusion of the positioning block passes through the product, thereby fixing the product between the positioning element and the drive component. This prevents shaking during the displacement of the base caused by the drive mechanism or deformation during riveting by the riveting mechanism, further improving the product yield of the riveting device.

In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0046] like Figure 1 As shown, the present invention provides a riveting device 100, which includes a base 10, a positioning mechanism 20, a riveting mechanism 30, and at least one detection element 40 (see reference). Figure 2 The base 10 has a drive mechanism 50 and a positioning mechanism 20 located on top of it. The positioning mechanism 20 includes two drive components 21 arranged opposite each other along a first horizontal direction and a positioning element 22 located between the drive components 21. The drive components 21 and the positioning element 22 are used to position the side surface 210 and the bottom surface 220 of the product 200, respectively (see reference). Figure 2 The riveting mechanism 30 is located above the positioning mechanism 20, and the riveting mechanism 30 includes a pressing assembly 31 protruding toward the base 10 (see reference). Figure 5 The crimping assembly 31 is configured to move in a controlled vertical direction. All detection elements 40 are mounted on the drive assembly 21. The detection elements 40 are configured to selectively detect the structure of the product 200 and / or the placement position of the connecting strip 300 riveted to the product 200. The drive mechanism 50 is connected to the bottom of the base 10 and is configured to drive the base 10 to move towards the crimping mechanism 30 in a second horizontal direction, so as to move the base 10 and the positioning mechanism 20 to the bottom of the crimping mechanism 30, so that the crimping assembly 31 moves downward in a controlled manner to rivet the product 200 and the connecting strip 300 (see reference). Figure 2 The target position is the second horizontal direction, which is perpendicular to the first horizontal direction. Here, the number of detection elements 40 can be one, two, or more. The detection elements 40 can be used to detect whether the structure of the product 200 meets the requirements, or to detect whether the connecting strip 300 is placed at the riveting position. The target position is the position where the crimping assembly 31 completely rivets the product 200 and the connecting strip 300.

[0047] In this embodiment, the initial positioning of the product 200 and the connecting strip 300 is achieved by sequentially installing the product 200 on the positioning member 22 and snapping it between the two drive components 21, and placing the connecting strip 300 on top of the product 200. Then, the placement position of the connecting strip 300 and / or the structure of the product 200 are detected by the detection member 40. After determining that the structure of the product 200 meets the requirements and / or the connecting strip 300 is correctly placed, the drive mechanism 50 drives the base 10 to move the product 200 toward the riveting mechanism 30. After moving to the bottom of the riveting mechanism 30, the crimping component 31 is controlled to move down to the target position for riveting the product 200 and the connecting strip 300. This improves the production efficiency of the riveting device 100 and increases the yield of the riveted product 200, preventing the product 200 from having a non-standard structure or the connecting strip 300 from being riveted without being placed in the device.

[0048] like Figure 3 As shown, in this embodiment, product 200 has an irregular support structure, meaning that product 200 is thin and has a complex structure. Product 200 includes multiple engaging members 230 that are arranged in pairs opposite each other and protrude from the surface of product 200. The connecting strip 300 is provided with limiting holes 310 corresponding to each engaging member 230 (see reference). Figure 4 After the product 200 is installed on the positioning component 22 and the drive component 21, the product 200 and the connecting strip 300 are initially positioned by the snap-fit ​​component 230 of the product 200 and the limiting hole 310 of the connecting strip 300. This prevents the product 200 and the connecting strip 300 from being misaligned during the riveting process, which would result in poor riveting quality and further improve the riveting success rate of the riveting device 100.

[0049] like Figure 5 As shown, in this embodiment, the riveting mechanism 30 is configured to be suspended above the base 10 and protrude towards the base 10. The riveting mechanism 30 includes a driving member for driving the pressing assembly 21 to move up and down, and the driving assembly 21 includes a engaging member 230 (see reference). Figure 3 The corresponding pressing component (not shown) is configured such that when the driving mechanism 50 moves the base 10 to the bottom of the product 200 and the connecting strip 300, the driving component of the riveting mechanism 30 is configured to move the pressing component down to abut against the locking component 230 of the product 200 and continue to move down so that the locking component 230 is riveted to the surface of the connecting strip 300. After the riveting is completed, the pressing component is controlled to move up to facilitate subsequent riveting.

[0050] In a further embodiment, the detection element 40 is a photoelectric detector. Photoelectric detectors are characterized by high detection accuracy and fast response speed. Using a photoelectric detector for the detection element 40 not only improves its detection accuracy but also its response speed, thus facilitating increased production efficiency and capacity of the riveting device 100. Specifically, when the detection element 40 is used to detect whether the structure of the product 200 has extra holes or holes not formed in standard positions, the photoelectric detector emits and receives corresponding light and electrical signals, enabling rapid detection of whether the structure of the product 200 meets standard requirements, thereby achieving rapid and accurate detection of the product 200's structure. In other embodiments, the detection element 40 can also be an infrared sensor; the type of detection element 40 is not limited here.

[0051] like Figure 2 As shown, in a further embodiment, the drive assembly 21 also includes a cylinder 211 (see reference). Figure 7 The cylinder 211 is located on the side of the cylinder 211 near the positioning member 22, and the positioning block 213 is provided with a positioning protrusion 215 on the side of the positioning block 213 near the positioning member 22. In this embodiment, a positioning member 22 is provided between the two drive components 21, and a positioning block 213 is provided on the side of each drive component 21 near the positioning member 22. Each positioning block 213 is provided with a positioning protrusion 215 that is aligned with the product 200 (see reference). Figure 3 The positioning protrusion 215 is provided accordingly so that when the cylinder 211 drives the positioning block 213 to move toward the product 200, the positioning protrusion 215 of the positioning block 213 passes through the product 200 to fix the product 200 between the positioning member 22 and the drive assembly 21, so as to prevent the driving mechanism 50 from shaking during the displacement of the base 10 or the riveting mechanism 30 from deforming during riveting, and further improve the product 200 yield of the riveting device 100.

[0052] like Figure 7 As shown, in a further embodiment, the top surface of the positioning block 213 is provided with a limiting groove 214, which is used to limit the connecting strip 300. In this embodiment, by providing a limiting groove 214 matching the connecting strip 300 on the top surface of the positioning block 213, the possibility of deformation of the connecting strip 300 is reduced when the pressing assembly 31 of the riveting mechanism 30 applies pressure to the connecting strip 300. At the same time, the setting of the limiting groove 214 can initially limit the connecting strip 300, preventing it from shaking and shifting when the base 10 moves the product 200 and the connecting strip 300.

[0053] like Figure 7As shown, in a further embodiment, the detection element 40 is located near the limiting groove 214 on the positioning block 213 to detect the placement position of the connecting strip 300. In this embodiment, the detection element 40 is configured to extend along the second horizontal direction and is positioned near the limiting groove 214 to detect whether the connecting strip 300 is placed in the limiting groove 214. This prevents the engaging part 230 from being flattened after riveting the product 200 without the connecting strip 300, thus preventing the product 200 from being riveted to the connecting strip 300 again, thereby reducing the production defect rate of the riveting device 100.

[0054] In a further embodiment, the positioning block 213 is also provided with a mounting hole extending along a first horizontal direction, and the detection element 40 is disposed in the mounting hole to detect the structure of the product 200. In this embodiment, the bottom surface 220 of the product 200 engages with the positioning element 22, and the side surface 210 of the product 200 engages with the positioning protrusion 215 of the positioning block 213. By disposing the detection element 40 in the mounting hole of the positioning block 213, the detection element 40 can detect the structure of the side surface 210 of the product 200, preventing the subsequent riveting steps from being performed due to too many or too few holes in the product 200, which would lead to a decrease in the yield of the riveted product 200. In other embodiments, the detection element 40 can also be disposed on the positioning element 22 to detect the structure of the bottom surface 220 of the product 200.

[0055] like Figure 6 As shown, in a further embodiment, the riveting device 100 further includes at least one limiting component 60, which is located at one end of the base 10 and is configured to limit the base 10. In this embodiment, the drive mechanism 50 is configured to drive the base 10 to move along a second horizontal direction after the product 200 and the connecting strip 300 are installed on the positioning mechanism 20, and to drive the base 10 back to its initial position along the second horizontal direction after riveting. That is, the drive mechanism 50 is configured to drive the base 10 to reciprocate along the second horizontal direction. The limiting component 60 is located at the initial position of the positioning mechanism 20 and at the end of the base 10, so that when the drive mechanism 50 drives the base 10 back to its initial position, the limiting component 60 limits the base 10 to prevent the product 200 from shaking due to the inertial force generated by the sudden stop of the base 10, thereby preventing the product 200 from falling.

[0056] like Figure 6As shown, in a further embodiment, the limiting assembly 60 further includes a limiter 61 and a buffer 62. The limiter 61 extends along a second horizontal direction and is configured to limit the end face of the base 10. The buffer 62 is parallel to the extending direction of the limiter 61 and is configured such that its end protrudes from the end of the limiter 61 toward the base 10. In this embodiment, by providing a limiter 61 and a buffer 62 in each limiting assembly 60, and configuring the buffer 62 such that its end protrudes from the end of the limiter 61 toward the base 10, the base 10 first abuts against the buffer 62 during the process of the drive mechanism 50 moving the base 10 to the initial position. This allows the buffer 62 to initially decelerate and limit the base 10, and stops the base 10 when it abuts against the end of the limiter 61. This achieves double limiting of the base 10, preventing the base 10 from slipping off the slide rail 51 or stopping abruptly when it moves to the initial position, thus preventing excessive inertial force.

[0057] In a further embodiment, the buffer 62 is a hydraulic buffer 62, which can effectively reduce the vibration and noise generated by the automated equipment during operation. The base 10 first contacts the buffer 62 before being controlled to move to the initial position, so that the hydraulic buffer 62 can absorb and mitigate the impact force through its internal hydraulic system, thereby significantly reducing the vibration and noise level. This helps to improve the stability and accuracy of the riveting device 100, and at the same time enables the riveting device 100 to operate more smoothly and quickly, thereby improving production efficiency.

[0058] In a further embodiment, the drive mechanism 50 further includes at least one slide rail 51 and at least one slider 52 corresponding to each slide rail 51. The slide rail 51 is configured to extend along a second horizontal direction, and the slider 52 is configured to move along the extension direction of the slide rail 51. In this embodiment, by configuring the drive mechanism 50 so that the slide rail 51 and the slider 52 cooperate, and the slider 52 is configured to be connected to the base 10, the base 10 is driven to move towards the pressing assembly 31 along the extension direction of the slide rail 51 under the action of the drive mechanism 50. This makes the operation of the base 10 have a certain guiding characteristic, that is, the drive mechanism 50 only needs to control the running accuracy of the base 10 in the extension direction of the guide rail, thereby improving the running stability of the base 10, ensuring the positioning accuracy of the product 200 on the base 10, and improving the riveting efficiency of the riveting mechanism 30. Here, the number of slide rails 51 can be one, two, or more, and the number of sliders 52 can be one, two, or more.

[0059] In a preferred embodiment, when there are two slide rails 51, there are also two sliders 52. The two slide rails 51 are symmetrically arranged about the base 10 to provide a uniformly distributed support force to the base 10, thereby further improving the operational stability of the base 10.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
