In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0041] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0042] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "provided with", "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0043] like Figures 1 to 5As shown, a rivet feeding device is used to convey rivets to a riveting gun, comprising: a loading component, a limiting component 4, a feeding component 5 and a control system 6.

[0044] The feeding assembly is used to deliver the rivets to the feeding assembly 5. The limiting assembly 4 is used to limit the number of rivets entering the feeding assembly 5.

[0045] The feeding assembly 5 comprises: a feeding chamber 51 and a power mechanism. The feeding chamber 51 has a feeding port, which is connected to the loading assembly and can be opened or closed automatically. The power mechanism is used to provide a driving force to transport the rivet from the feeding chamber 51 to the rivet gun.

[0046] The control system 6 is connected to the material limiting component 4 and the material feeding component 5 , and the control system 6 is used to control the power mechanism to output the driving force when the rivets in the material feeding chamber 51 reach a predetermined value.

[0047] The technical solution of the present application is to place the rivets on the loading assembly, and to convey the rivets to the feeding assembly 5 through the loading assembly. During the rivet conveying process, the limiting assembly 4 limits the number of rivets entering the feeding chamber 51. When the number of rivets in the feeding chamber 51 reaches a predetermined value, the limiting assembly 4 limits the rivets from entering the feeding chamber 51, and the power mechanism outputs a driving force to convey the rivets to the riveting gun. This facilitates workers to quickly install the rivets on the riveting gun, thereby improving the riveting efficiency.

[0048] like Figures 3 to 5 As shown, the feeding assembly includes: a feeding mechanism 2 and a feeding slide rail. The rivets to be fed are placed in the feeding mechanism 2, the feeding end of the feeding slide rail is connected to the feeding mechanism 2, and the discharging end of the feeding slide rail is connected to the feeding chamber 51. The feeding slide rail is used to slide the rivets from the outlet end of the feeding mechanism 2 to the feeding chamber 51.

[0049] The rivets to be used are placed in the feeding mechanism 2. In this embodiment, the feeding mechanism 2 is a vibration plate. The rivets are transported to the feeding slide rail through the vibration plate. The feeding slide rail is tilted downward so that the rivets slide on the feeding slide rail due to gravity and enter the feeding chamber 51. In the specific implementation, the tilt angle of the feeding slide rail should ensure that the rivets slide normally on the feeding slide rail.

[0050] In other embodiments, the feeding mechanism 2 is a vibration plate, and the feeding slide is connected to the feeding mechanism 2. During the feeding process of the feeding mechanism 2, the feeding slide and the feeding mechanism 2 vibrate synchronously, and the rivets on the feeding slide continue to move due to the vibration, so that the rivets move into the feeding chamber 51.

[0051] like Figures 4 to 5As shown, the material limiting component 4 includes: a monitoring mechanism 41. A monitoring hole is provided on the feeding slide rail, and the monitoring hole is arranged corresponding to the monitoring mechanism 41. The monitoring mechanism 41 is used to monitor the number of rivets on the feeding slide rail through the monitoring hole. The control system 6 can close or open the feeding mechanism 2 according to the number of rivets monitored by the monitoring mechanism 41.

[0052] Start monitoring holes on the feeding rail so that the monitoring mechanism 41 can monitor the number of rivets on the feeding rail. When the number of rivets monitored by the monitoring mechanism 41 reaches a predetermined value, the number of rivets on the feeding rail is relatively large. The control system 6 can close the feeding assembly to stop feeding, thereby avoiding the phenomenon of congestion and falling caused by a large number of rivets on the feeding rail.

[0053] like Figures 3 to 5 As shown, the material limiting assembly 4 includes: a material limiting mechanism. The material limiting mechanism includes: a driving member 42 and a closing plate 43, the output end of the driving member 42 is connected to the closing plate 43, and the driving member 42 is arranged on the feeding chamber 51. A closing opening is opened on the closing plate 43, and the driving member 42 is suitable for driving the closing plate 43 to move when the rivet needs to enter the feeding chamber 51, so that the closing opening corresponds to the feeding opening.

[0054] The closing plate 43 is disposed on one side of the feeding chamber 51 having the feeding port, and is slidably disposed on the feeding chamber 51. The driving member 42 can drive the feeding chamber 51 to move, so that the closing port on the closing plate 43 overlaps or is misaligned with the feeding port. When the closing port overlaps with the feeding port, the rivet can enter the feeding chamber 51.

[0055] like Figures 4 to 7 As shown, the material limiting mechanism also includes: a material limiting plate 44. The material limiting plate 44 includes: a first baffle and a second baffle, and the first baffle and the second baffle are respectively located on both sides of the feeding slide rail. The first baffle and the second baffle are both connected to the closing plate 43, and the first baffle and the second baffle are staggered. A first clamping plate is provided on the side of the first baffle close to the feeding slide rail, and a second clamping plate is provided on the side of the second baffle close to the feeding slide rail. The driving member 42 drives the first baffle and the second baffle to alternately block the path of the feeding slide rail, so that the rivets pass through the first baffle and the second baffle in sequence.

[0056] The first baffle and the second baffle move synchronously with the closing plate 43. When the closing port overlaps with the feeding port, the first baffle blocks the feeding slide rail and the rivet stays on the first baffle. When the closing port and the feeding port are misaligned, the first baffle moves away and the second baffle blocks the feeding slide rail. During this process, the rivet falls from the first baffle and stays on the second baffle. The driving member 42 drives again to make the closing port overlap with the feeding port, and the rivet passes through the second baffle from the gap between the first baffle and the second baffle, so that the rivet passes through the closing port and the feeding port and enters the feeding chamber 51.

[0057] In this embodiment, according to the number of rivets to be fed at a time, by adjusting the size of the gap between the first baffle and the second baffle, the number of rivets passing through the second baffle at a time can be adjusted, thereby adjusting the number of rivets entering the feeding chamber 51, thereby adjusting the number of rivets transported.

[0058] like Figures 1 to 6 As shown, the driving member 42 is also suitable for driving the closing plate 43 to move when the rivet needs to be transported from the feeding chamber 51 to the rivet gun, so that the closing port and the feeding port are staggered. The power mechanism includes: a compressed air unit 55 and a pneumatic tube 52. The output end of the compressed air unit 55 is connected to the pneumatic tube 52, and the pneumatic tube 52 is connected to the feeding chamber 51. The compressed air unit 55 is used to provide the driving force.

[0059] When the driving member 42 drives the closing plate 43 to move to the position where the closing port and the feed port are misaligned, the compressed air unit 55 outputs compressed air to the feeding chamber 51 through the pneumatic tube 52, and the rivet in the feeding chamber 51 is pushed to move by the gas pressure, thereby driving the rivet to the rivet gun.

[0060] like Figure 6 As shown, the feeding assembly 5 further includes a feeding pipe 53, which is connected to the discharge end of the feeding chamber 51. The feeding chamber 51 is provided with a card insert 54, which is arranged corresponding to the connection between the feeding pipe 53 and the feeding chamber 51.

[0061] The rivets in the feeding chamber 51 are driven by a power mechanism, and the driving force pushes the rivets to move to the riveting gun in the feeding tube 53. The end of the feeding tube 53 is connected to the feeding chamber 51 through a card plug 54. According to the type and size of the rivets to be fed, different types of feeding tubes 53 can be replaced to feed different rivets.

[0062] like Figures 1 to 3As shown, it also includes: a vehicle body assembly. The vehicle body assembly includes a vehicle frame 1 and a moving mechanism 12. The loading assembly, the material limiting assembly 4, the feeding assembly 5 and the control system 6 are all arranged on the vehicle frame 1, and the moving mechanism 12 is arranged on the vehicle frame 1. The vehicle frame 1 is also provided with a placement seat 13, and the rivet gun is arranged on the placement seat 13.

[0063] The frame body 1 can move freely through the moving mechanism 12, so that the rivet feeding device can be moved to the site where riveting is required. After the riveting work is completed, the used rivet gun can be placed on the placement seat 13, so that the workers can use it at any time.

[0064] In general, the present application provides a rivet feeding device, which places the rivets to be used into the feeding mechanism 2. The rivets are fed to the feeding slide rail by the feeding mechanism 2, and the rivets are slid on the feeding slide rail. During the rivet feeding process, the limiting component 4 limits the number of rivets entering the feeding chamber 51. When the number of rivets in the feeding chamber 51 reaches a predetermined value, the limiting component 4 limits the rivets from entering the feeding chamber 51, and the power mechanism outputs a driving force to feed the rivets to the riveting gun. This facilitates workers to quickly install rivets on the rivet gun, thereby improving riveting efficiency.

[0065] In summary, the above embodiments provided by the present invention are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
