Description

Technical Field

[0001] This invention relates to the technical field of riveting, specifically to sheet metal, sheet metal connecting devices, fasteners, and methods for installing sheet metal connecting devices. Background Technology

[0002] In existing technologies, the fastening of some small electronic components is generally achieved through riveting. However, those skilled in the art have discovered that riveting leaves indentations. These indentations reduce the rigidity of the electronic components and affect their installation.

[0003] Furthermore, not only will it leave indentations, but the pressure can also be transmitted too quickly during the riveting process, significantly reducing the effectiveness of the riveting and making the riveting joint between parts prone to failure. Moreover, the application environment for riveting is too limited; in the riveting of many complex parts, the difficulty of using riveting increases considerably.

[0004] There is currently no effective solution to the above problems.

[0005] It should be noted that the above description of the technical background is only for the purpose of clearly and completely explaining the technical solutions of the present invention and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of the present invention. Summary of the Invention

[0023] The serrations are arranged circumferentially on the outer side of the main body.

[0024] Two flanges are symmetrically arranged on the main body and are located on both sides of the tooth pattern.

[0025] Preferably, the fasteners fall directly into the first mounting groove of the plate after being fed by the vibratory feeder, without needing to be identified by a CCD camera on the flange.

[0049] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0050] In the description of this invention, it should be noted that the terms "upper," "middle," "lower," "inner," "outer," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The embodiments of this invention will now be described according to its overall structure.

[0051] The inventors of this application have discovered that press riveting is generally used during the riveting process. Press riveting results in noticeable burrs and indentations on the riveted sheet metal 100. Furthermore, press riveting is difficult to operate when riveting sheet metal 100 with different structures, especially when riveting sheet metal with obstructions or external parts; it is not only inefficient but also has a high scrap rate.

[0052] The inventors discovered that applying spin riveting to the riveting of sheet metal 100, which is prone to leaving burrs and indentations, can avoid defects caused by press riveting. At the same time, spin riveting avoids the influence of the sheet metal structure on the riveting process, greatly reducing the scrap rate and improving processing efficiency.

[0053] Based on the above inventive concept, in some embodiments, reference is made to... Figure 1-8 As shown in the figure, an embodiment of this application provides a sheet material, including:

[0054] The plate 100 has a mounting surface 110, and the mounting surface 110 of the plate 100 has a first mounting groove 111 and a second mounting groove 112 that are recessed downwards. The first mounting groove 111 is used for placing the fastener 200, and the second mounting groove 112 is used for moving the riveting tool 300 for riveting. A mounting wall 113 for riveting and fixing with the fastener 200 is provided between the first mounting groove 111 and the second mounting groove 112.

[0055] The second mounting slot 112 is either unclosed or intermittent.

[0056] In actual operation by those skilled in the art, the plate 100 is provided with a mounting surface 110. A first mounting groove 111 and a second mounting groove 112 are provided on the mounting surface 110, both of which are downwardly recessed. In the specific processing, the first mounting groove 111 is used to mount the fastener 200, and the second mounting groove 112 is used to mount the riveting tool 300. That is, during the riveting process, the fastener 200 is placed into the first mounting groove 111, and then the riveting tool 300 is placed into the second mounting groove 112. The riveting tool 300 in the second mounting groove 112 is used to rivet the fastener 200 to the plate 100. It is understood that a mounting wall 113 for riveting and fixing the fastener 200 is provided between the first mounting groove 111 and the second mounting groove 112. The mounting wall 113 is pressed by the riveting tool 300, thereby achieving the tightening of the fastener 200.

[0057] It is worth noting that, during actual operation, the inventors of this application discovered that many processing situations arise when riveting the sheet metal 100. For example, the sheet metal 100 may require external parts, or the shape of the sheet metal 100 may significantly affect the riveting process, resulting in a decrease in the riveting effect. To address these issues, the inventors of this application have designed the second mounting groove 112 to be either unclosed or intermittent.

[0058] It is understood that in the above embodiments, the first mounting groove 111 is used to cooperate with the fastener 200, and the second mounting groove 112 is used to cooperate with the riveting tool 300. In this embodiment, the structure of the second mounting groove 112 is set to be unclosed or intermittent. When the structure of the second mounting groove 112 is set to be unclosed or intermittent, the second mounting groove 112 can cooperate with the riveting tool 300, and can also be connected to external parts through the second mounting groove 112.

[0059] Furthermore, when the structure of the second mounting groove 112 is set to be unclosed or intermittent, the plate 100 can be riveted in various ways.

[0060] Preferably, a stop 114 is formed above the mounting surface 110, and the stop 114 does not interfere with the second mounting groove 112. Those skilled in the art will know how to set the stop 114 above the mounting surface 110 and ensure that the stop 114 does not interfere with the second mounting groove 112. In the above embodiments, the sheet metal 100 is riveted, and the structure of the second mounting groove 112 is set to be either open or intermittent. In this embodiment, the stop 114 is set above the mounting surface 110. The setting of the stop 114 allows the mounting surface 110 of the sheet metal 100 to be riveted in more processing situations. The stop 114 does not interfere with the second mounting groove 112. That is, the stop 114 does not affect the cooperation between the second mounting groove 112 and the riveting tool 300. This structure allows the sheet metal 100 to maintain stable riveting in more processing situations (such as adding more obstructions through the stop or connecting external parts through the stop).

[0061] It is understood that, in specific configurations, those skilled in the art can provide multiple stops 114. The maximum distances from the multiple stops 114 to the mounting surface 110 of the sheet metal 100 may be the same or different. The maximum distance from the stop 114 to the mounting surface 110 of the sheet metal 100 can be defined as the setting height of the stop 114. Those skilled in the art can set the setting heights of the multiple stops 114 to be the same or different. This further satisfies the requirement that the sheet metal 100 can be riveted when connected to more different parts. It is worth noting that the number of stops 114 is not unlimited. Setting the number of stops 114 will not interfere with the second mounting groove 112, thereby ensuring that a certain number of stops 114 will not affect the stable riveting process.

[0062] In this embodiment, those skilled in the art will configure the sheet metal 100 to be riveted. A mounting wall 113 is provided between the first mounting groove 111 and the second mounting groove 112 of the sheet metal 100. The mounting wall 113 can cooperate with the fastener 200 in the first mounting groove 111 and the riveting tool 300 in the second mounting groove 112. Specifically, after the fastener 200 is installed into the first mounting groove 111, the mounting wall 113 is pressed by the riveting tool 300. Under pressure, the mounting wall 113 can cooperate with the fastener 200, thereby achieving the riveting of the sheet metal 100. Preferably, the shapes of the inner and outer walls of the mounting wall 113 correspond and match.

[0063] It is understood that the inner wall of the mounting wall 113 engages with the fastener 200, while the outer wall engages with the riveting tool 300. For stable riveting, the outer and inner walls of the mounting wall 113 need to be configured to engage. More preferably, both the inner and outer walls of the mounting wall 113 are curved surfaces. In a specific configuration, the inner and outer walls of the mounting wall 113 are set as engaging curved surfaces. This allows the riveting tool 300 to stably rivet the sheet metal 100 through the mounting wall 113 and the fastener 200.

[0064] In other embodiments of this application, a stop 114 is formed above the mounting surface 110. The stop 114 does not interfere with the second mounting groove 112, which is either unclosed or intermittent. In this embodiment, both the inner and outer walls of the mounting wall 113 are curved surfaces, which ensures that the sheet metal 100 can maintain stable riveting under various processing conditions.

[0065] Preferably, the second mounting groove 112 has at least one opening, and the stop 114 is located at the opening of the second mounting groove 112. In one embodiment, the second mounting groove 112 on the sheet metal 100 is provided with at least one opening. Simultaneously, the stop 114 is disposed at the opening of the second mounting groove 112. The second mounting groove 112 is used to cooperate with the riveting tool 300. In this embodiment, the stop 114 is disposed at the opening of the second mounting groove 112, so that the sheet metal 100 can still be stably riveted even when the stop 114 is disposed at the opening of the second mounting groove 112.

[0066] Preferably, the second mounting groove 112 is arc-shaped, and the angle of the second mounting groove 112 is between 180 degrees and 360 degrees. In this embodiment of the smart pot, the second mounting groove 112 is arc-shaped, and the angle of the second mounting groove 112 is set to 180 degrees to 360 degrees. Within this selected angle range, the second mounting groove 112 can cooperate well with the riveting tool 300. That is, within this selected angle range, the riveting operation of the riveting tool 300 can remain basically stable, and the riveting effect on the sheet metal 100 can be greatly improved.

[0067] It is worth noting that during actual riveting, the cross-sectional shape of the fastener 200 can be polygonal, meaning it is not in full contact with the inner wall of the second mounting groove 112. In other words, the angle between the contact portion of the fastener 200 and the second mounting groove 112 can be less than 360 degrees.

[0068] Preferably, the second mounting groove 112 includes one or more of the following shapes: arc-shaped, polygonal, and multi-segment. In the specific implementation process by those skilled in the art, the second mounting groove 112 cooperates with the riveting tool 300, and may also cooperate with external parts. The inventors of this application have configured the second mounting groove 112 to include one or more of the following shapes: arc-shaped, polygonal, and multi-segment. During implementation, the second mounting groove can be specifically configured according to actual needs, thereby satisfying the requirements of various specific riveting processes for the sheet metal 100.

[0069] This application also provides a plate connecting device, including:

[0070] The plate 100 has a mounting surface 110, and the mounting surface 110 has a first mounting groove 111 and a second mounting groove 112 that are recessed downwards; wherein, a mounting wall 113 for riveting and fixing with a fastener 200 is provided between the first mounting groove 111 and the second mounting groove 112.

[0071] Fastener 200 is disposed in the first mounting groove 111, and the joint between fastener 200 and mounting wall 113 is unclosed or intermittent.

[0072] For this plate connecting device, a mounting surface 110 is provided on the plate 100. The mounting surface 110 of the plate 100 has a first mounting groove 111 and a second mounting groove 112 that are recessed downwards. A mounting wall 113 for riveting and fixing with a fastener 200 is provided between the first mounting groove 111 and the second mounting groove 112. In actual operation, the fastener 200 is installed into the first mounting groove 111, and the second mounting groove 112 is used to install the riveting tool 300.

[0073] That is, during the riveting process, the fastener 200 is placed into the first mounting groove 111, and then the riveting tool 300 is placed into the second mounting groove 112. The riveting tool 300 in the second mounting groove 112 is used to rivet the fastener 200 to the plate 100. It can be understood that a mounting wall 113 for riveting and fixing the fastener 200 is provided between the first mounting groove 111 and the second mounting groove 112. The mounting wall 113 is pressed by the riveting tool 300, thereby achieving the tightening of the fastener 200.

[0074] In the settings of those skilled in the art, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The joint between the fastener 200 and the mounting wall 113 is either unclosed or intermittent. During operation, the sheet metal 100 may be riveted in various situations (the structure of external parts or the sheet metal may affect riveting). The fact that the joint between the fastener 200 and the mounting wall 113 is unclosed or intermittent allows the sheet metal 100 to be reliably riveted in multiple situations.

[0075] The cross-sectional shape of the fastener 200 can be set to arc or polygon. That is, the circumferential angle of the joint between the fastener 200 and the mounting wall 113 can be less than 360 degrees. In other words, the plate 100 can be riveted with a variety of fasteners 200.

[0076] The joint has a notch, and a stop 114 is provided on the plate 100 above the opposite position of the notch. The joint has a notch, and the stop 114 is provided above the opposite position of the notch, specifically, the stop 114 is provided on the plate 100 above the opposite position of the notch.

[0077] The baffle 114 is provided on the plate 100, which can ensure that the riveting process can still be carried out stably even when multiple parts are provided on the mounting surface 110 of the plate 100.

[0078] Preferably, no second mounting groove 112 is provided below the stop 114. This structure means that the stop 114 and the second mounting groove 112 do not interfere with each other. During the actual riveting process, the stop 114 will not affect the cooperation between the second mounting groove 112 and the riveting tool 300, further ensuring that the sheet metal 100 is riveted stably.

[0079] In summary, for the plate connecting device, the plate 100 has a mounting surface 110, and the mounting surface 110 of the plate 100 has a downwardly recessed first mounting groove 111 and a second mounting groove 112. A mounting wall 113 for riveting and fixing with a fastener 200 is provided between the first mounting groove 111 and the second mounting groove 112. During the riveting process, the fastener 200 is placed into the first mounting groove 111, and then the riveting tool 300 is placed into the second mounting groove 112. The fastener 200 is riveted to the plate 100 using the riveting tool 300 in the second mounting groove 112. The joint between the fastener 200 and the mounting wall 113 is either unclosed or intermittent. The second mounting groove 112 is not provided below the stop 114.

[0080] This application also provides a fastener, comprising:

[0081] Main body 210;

[0082] The serrations 211 are arranged circumferentially on the outer side of the main body 210;

[0083] Two flanges 220 are symmetrically arranged on the main body 210 and are located on both sides of the toothed 211.

[0084] like Figure 1 and Figure 7 As shown, in the specific configuration, two flanges 220 are installed on both sides of the main body 210, and the center of the main body 210 and the center of the two flanges 220 are on the same straight line.

[0085] Preferably, after being fed by the vibratory feeder, the fastener 200 falls directly into the first mounting groove 111 of the plate without needing to be identified by the flange 220 by a CCD camera.

[0086] Two flanges 220 are symmetrically arranged on both sides of the main body 210 to facilitate the installation of the fastener 200. During the installation of the flanges 210, a vibratory feeder is used to install the flanges 220 into the grooves on the plate 100 that require riveting. In existing operations, only one side of the main body 210 has the flanges 220 installed, so a CCD camera is needed to identify and correct their position during installation. The inventors of this application found that this step reduces the efficiency of riveting in practice. In this embodiment, the two flanges 220 are symmetrically arranged on both sides of the main body 210. This arrangement eliminates the need to continue using a CCD camera to observe and correct the position of the fastener 200, thus facilitating the installation of the fastener 200.

[0087] In the actual operation of those skilled in the art, according to Figure 7 Preferably, the outermost edge of the tooth 211 is located inside the outermost edge of the flange 220. By setting the outermost edge of the tooth 211, during the riveting process between the fastener 200 and the plate 100, the stability of the overall structure of the fastener 200 can be ensured when pressure is applied to the fastener 200 through the mounting wall 113, thereby ensuring the reliability of the riveting of the plate 100 under various conditions.

[0088] This application also provides a method for installing a plate connecting device, including the following steps:

[0089] The fastener 200 is placed in the first mounting groove 111 of the plate 100 by a vibratory feeder;

[0090] Insert the riveting tool 300 into the second mounting slot 112;

[0091] While the riveting tool 300 abuts against the mounting wall 113, the riveting tool 300 moves within the second mounting groove 112, thereby engaging the fastener 200 with the mounting wall 113 by riveting. The movement trajectory of the riveting tool 300 is either unclosed or intermittent.

[0092] Those skilled in the art first place the fastener 200 into the first mounting groove 111 of the plate 100 using a vibratory feeder. After the fastener 200 is installed, the riveting tool 300 is inserted into the second mounting groove 112 on the plate 100. By applying external force, the riveting tool 300 moves within the second mounting groove 112, causing the fastener 200 to engage with the mounting wall 113 through riveting. It is worth noting that the movement trajectory of the riveting tool 300 is either open or intermittent. The movement trajectory of the riveting tool 300 can be either reciprocating motion or a single motion, or a combination thereof. Specifically, the cross-section of the first mounting groove 111 can be non-circular, meaning it can have one or more segments that are not fully formed, and the angle of each segment can be the same or different. Figure 8 The cross-section of the fastener 200 can be irregular in shape. The trajectory of the riveting tool 300 is set so that effective and stable riveting can be performed when the sheet metal 100 has various structures or various types of external parts.

[0093] Preferably, in the step of "placing the fastener in the first mounting groove of the plate using a vibratory feeder", the fastener 200 has two symmetrical flanges 220, thus eliminating the need for image recognition to identify the orientation of the fastener 200. The fastener 200 is symmetrically positioned on both sides of the main body 210 by the two flanges 220, meaning that the flanges 220 on the fastener 200 do not interfere with the continued riveting process, eliminating the need for image recognition to identify the orientation of the fastener 200 and greatly improving riveting efficiency.

[0094] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. Slightly modified implementations based on certain industry standards or custom methods or embodiments can also achieve the same, equivalent, or similar, or predictable, implementation effects as the above embodiments. Embodiments applying these modified or modified data acquisition, processing, output, and judgment methods still fall within the scope of optional implementations of this application.

[0095] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.

Insert the riveting tool into the second mounting slot; While the riveting tool abuts against the mounting wall, it moves within the second mounting groove, thereby engaging the fastener with the mounting wall through riveting. The movement trajectory of the riveting tool is either non-closed or intermittent in the circumferential direction, including any one or a combination of reciprocating motion or single motion, thereby enabling effective and stable riveting even when the sheet metal has multiple structures or multiple types of external parts.
