[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] Please refer to Figures 1 to 5 An embodiment of the present application provides a feeding system 100 for delivering rivets to a riveting gun, including a feeding device 10, a loading device 20 and a replenishing device 30.

[0038] like Figure 2 As shown, the feeding device 10 comprises a vibration plate 101 for outputting rivets and a feeding pipe connected to the vibration plate 101. The rivets outputted from the vibration plate 101 can be transferred into the feeding pipe and transported to the next device by the feeding pipe.

[0039] like Figure 5 As shown, the feeding device 20 is installed on the riveting gun, including a storage bin 202 for storing rivets and a feeding pipe 203 connected to the storage bin 202, and one end of the feeding pipe 203 away from the storage bin 202 is connected to the rivet gun head. The storage bin 202 is used to receive and store the rivets delivered by the feeding device 10, and then deliver these rivets to the rivet gun head through the feeding pipe 203. Furthermore, in the process of delivering the rivets, the rivets are always delivered in an upright form, so the shapes of the through holes in the storage bin 202 and the feeding pipe 203 for delivering the rivets should also match the shape of the rivets when they are upright.

[0040] The replenishing device 30 is connected to the feeding pipe to store the rivets output by the feeding device 10 and to replenish the rivets to the storage bin 202. The loading device 20 can be connected to the replenishing device 30 to replenish the rivets in the replenishing device 30 to the storage bin 202, so that the storage bin 202 can supply the riveting gun separately.

[0041] The feeding system 100 also includes a first air source and a second air source. The first air source is used to supply air to the feeding pipeline, so as to blow the rivets output from the vibration plate 10 to the replenishing device 30 through the feeding pipeline; the second air source is used to supply air to the loading pipeline 203, so as to blow the rivets in the storage bin 202 to the rivet gun head through the loading pipeline 203. The first air source and the second air source can be arranged outside and connected to the feeding pipeline and the loading pipeline 203 through the air inlet pipe to supply air, or they can supply air to the feeding pipeline and the loading pipeline 203 through the air holes arranged on the feeding device 10 and the loading device 20, respectively.

[0042] When the feeding system 100 is working, the rivets are first sorted and output to the replenishing device 30 through the feeding device 10, and the rivets are stored in the replenishing device 30; then, the loading device 20 is connected to the replenishing device 30 to load the rivets in the replenishing device 30 into the loading device 20; after the loading is completed, the connection between the loading device 20 and the replenishing device 30 is removed, and the loading device 20 is used to independently feed the rivet gun.

[0043] The above-mentioned feeding system 100 delivers rivets to the rivet gun head by blowing through a pipe, thereby avoiding the use of material strips, thereby eliminating the risk of material strip debris clogging the rivet gun head, and reducing the waste of material strips; at the same time, by fixing the feeding device 20 on the rivet gun, the two can move synchronously during riveting, and at this time, using a hose to blow rivets will not cause the hose to twist, thereby not limiting the swing range of the rivet gun.

[0044] According to some embodiments of the present invention, the feed pipeline includes a feed pipe 102 and a first hose 103 connected to the feed pipe 102, and a first air source supplies air to the first hose 103; one end of the feed pipe 102 away from the first hose 103 is connected to the vibration plate 101, and a first material distribution mechanism 104 is provided between the feed pipe 102 and the first hose 103, and the first material distribution mechanism 104 can distribute the rivets output from the feed pipe 102 to the air inlet end 1030 of the first hose 103. Figure 2 and Figure 3 As shown in the example, the first gas source is connected to the gas inlet end 1030 of the first hose 103 through an gas inlet pipe.

[0045] Furthermore, the first material distribution mechanism 104 may first receive the rivets output from the vibration plate 101, and then move the rivets to the air inlet end 1030 of the first hose 103, so that the rivets are blown into the hose 103. Specifically, Figure 2 and Figure 3 As shown, the first material distribution mechanism 104 includes a first material distribution cylinder 1041 and a first material distribution platform 1042 connected to the output end of the first material distribution cylinder 1041, the first material distribution platform 1042 is provided with a slot 10421, and the first material distribution platform 1042 can be switched between a first position and a second position; when the first material distribution platform 1042 is located at the first position, the rivet output by the vibration plate 101 falls into the slot 10421; when the first material distribution platform 1042 moves from the first position to the second position, the rivet in the slot 10421 moves to the air inlet end 1030 of the first hose 103, so that the rivet is blown into the first hose 103. Further, the shape of the opening 1031 of the cross section of the first hose 103 matches the shape of the rivet when it is upright, so that the rivet can be kept upright during the transmission process to avoid flipping.

[0046] In another embodiment, to ensure that the rivet does not leak out of the slot 10421, Figure 1 As shown, the first material distribution platform 1042 can also be placed against the baffle 105, so that when the rivet falls into the clamping groove 10421, the rivet can be supported by the baffle 105, and the rivet can move on the baffle 105 following the first material distribution platform 1042. At this time, the first hose 103 is inserted into the baffle 105, so that when the first material distribution platform 1042 is located in the second position, the clamping groove 10421 can be connected to the air inlet end 1030 of the first hose 103, and the first hose 103 is connected to the air source at the air inlet end 1030 using the air inlet pipe.

[0047] According to some embodiments of the present invention, the replenishing device 30 includes a replenishing bin 301 and a replenishing mechanism 303 disposed at one end of the replenishing bin 301. The end of the replenishing bin 301 away from the replenishing mechanism 303 is connected to the first hose 103. The replenishing mechanism 303 is used to connect to the storage bin 202 to control the opening or closing of the storage bin 202. During replenishment, the replenishing mechanism 303 controls the storage bin 202 to open, and the rivets in the replenishing bin 301 fall into the storage bin 202. After the replenishment is completed, the replenishing mechanism 303 controls the storage bin 202 to close. In this way, the rivets can be quickly replenished from the replenishing bin 301 to the storage bin 202, and after the replenishment is completed, the replenishing bin 301 continues to receive the rivets output from the feeding device 10 through the first hose 103, and so on, thereby ensuring a continuous supply of rivets.

[0048] Furthermore, the feeding mechanism 303 includes a feeding cylinder 3021 and a pull pin 3022 connected to the output end of the feeding cylinder 3021; Figure 6 As shown, a cover plate 201 is provided at one end of the material storage bin 202 connected to the feeding mechanism 303, and the cover plate 201 is provided with a pin hole 2011 cooperating with the pull pin 3022 and a slot hole 2012 matching the shape of the rivet when it is upright; after the material storage bin 202 is connected to the feeding mechanism 303, the pull pin 3022 is inserted into the pin hole 2011, and the pull pin 3022 can drive the cover plate 201 to move relative to the material storage bin 202.

[0049] Specifically, the cover plate 201 is slidably embedded in one end of the storage bin 201 connected to the feeding mechanism 303, and a connecting hole connected to the feeding mechanism 303 is opened on the edge of the end, and the connecting hole can be a pin hole or a threaded hole.

[0050] The pull pin 3022 is pulled by the feeding cylinder 3021 to drive the cover plate 201 to move relative to the storage bin 202, so that the slot 2012 is connected to the feeding bin 301, and the rivet in the feeding bin 301 passes through the slot 2012 under the action of gravity and falls into the storage bin 202.

[0051] According to some embodiments of the present invention, Figure 5 As shown, a second material distribution mechanism 204 is provided between the material storage bin 202 and the feeding pipe 203 , and the second material distribution mechanism 204 can distribute the rivets output from the material storage bin 202 to the air inlet end 2030 of the feeding pipe 203 .

[0052] Furthermore, the second material distribution mechanism 204 can receive the rivets output from the storage bin 202 and move the rivets to the air inlet end 2030 of the feeding pipe 203, so that the rivets are blown into the feeding pipe 203. Figure 5 and Figure 7 As shown, the second material distributing mechanism 204 includes a second material distributing cylinder 2041 and a second material distributing platform 2042 connected to the output end of the second material distributing cylinder 2041, the second material distributing platform 2042 is provided with a groove 20421 for carrying rivets, and the second material distributing platform 2042 can switch between a third position and a fourth position; when the second material distributing platform 2042 is located at the third position, the rivets output by the storage bin 202 fall into the groove 20421; when the second material distributing platform 2042 moves from the third position to the fourth position, the rivets in the groove 20421 move to the air inlet end 2030 of the feeding pipe 203, so that the rivets are blown into the feeding pipe 203.

[0053] Further, such as Figure 7As shown, the end surface of the rivet output end of the storage bin 202 is provided with an air port 2021 connected to the second air source, and when the second material distribution platform 2042 moves to the fourth position, the center of the air port 2021 is directly opposite to the groove 20421. By providing the air port 2021 on the end surface of the rivet output end of the storage bin 202, the air source can be independently set outside, and the feeding pipe 203 is supplied with air through the air port 2021, which shortens the distribution stroke of the second material distribution platform and improves the rivet delivery efficiency.

[0054] According to some embodiments of the present invention, the feeding pipe 203 is provided with a feeding platform 2031 and a second hose 2032 connected to the feeding platform 2031 in sequence along the conveying direction of the rivet, and the feeding platform 2031 is provided with a groove 20311 for guiding the rivet, and the groove 20311 is connected to the second hose 2032. By providing the groove 20311 on the feeding platform 2031, the conveying direction of the rivet can be adjusted to facilitate the connection between the second hose 2032 and the rivet gun head, avoid the second hose 2032 from twisting, and ensure the smooth conveying of the rivet.

[0055] Furthermore, the opening shape of the groove 20311 and the opening 20321 of the cross section of the second hose 2032 both match the shape of the rivet when it is erected. Figures 2 to 7 As shown in the example, the rivet used for riveting is in a "T" shape when standing upright, so that the opening of the groove 20311 and the opening of the cross section of the second hose 2032 are both "T"-shaped openings, and the groove 20421 and the groove 20311 are both provided with a step-type bearing portion to facilitate the rivet, so that the rivet can be kept upright during the entire transmission process, which is convenient for the subsequent punching of the rivet by the riveting gun.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0057] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
