[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figure 1 As shown, the rivet installation mechanism of this utility model embodiment includes a feeding component 100 and an installation component 200. The feeding component 100 includes N feeding channels, where N is a positive integer. The installation component 200 includes N rivet-driving devices, and the N rivet-driving devices are connected one-to-one with the N feeding channels. Each rivet-driving device is used to install the rivet delivered from the corresponding feeding channel onto the rivet-driving target.

[0036] like Figure 2 , Figure 3 and Figure 4 As shown, the feeding assembly 100 includes a feeding rack 110, a sliding block 120, a receiving block 130, N air inlet pipes 140 and N conveying pipes 150.

[0037] The loading rack 110 is adapted to move multiple rivets arranged sequentially along its length, and the loading rack 110 can be used as follows: Figure 2 and Figure 3 As shown, a vibratory feeder 111 and a rivet track 112 are used. Under the vibration of the vibratory feeder 111, the rivets arranged in sequence move along the rivet track to the sliding block 120. In other embodiments of this utility model, the feeding rack 110 can also be a magazine type, pushing the rivets to the sliding block 120 in a manner similar to pushing bullets from a magazine.

[0038] like Figure 3 and Figure 5 As shown, the sidewall of the sliding block 120 is connected to the end of the feeding rack 110. The sidewall of the sliding block 120 has multiple vertical feeding slots 121, which extend through the bottom of the sliding block 120. These feeding slots 121 are arranged sequentially along the length of the sliding block. The feeding slots 121 in the sliding block 120 form a discharge bin.

[0039] like Figure 5 and Figure 6 As shown, the receiving block 130 has N vertical receiving holes 131 inside, and N air pipe holes 132 through each of the N receiving holes 131 on its side wall. All N receiving holes 131 are through holes and are arranged sequentially along the length of the receiving block 130. When the sliding block 120 is driven to slide along the length of the receiving block 130, the feed groove 121 and the receiving holes 131 are aligned or misaligned. The receiving block 130, with its receiving holes 131 and air pipe holes 132, forms an air-blown feeding chamber.

[0040] like Figure 2 , Figure 3 and Figure 6 As shown, the ends of the N air inlet pipes 140 are connected to the N air pipe holes 132 in a one-to-one correspondence.

[0041] like Figure 2 , Figure 3 and Figure 5 As shown, the beginnings of the N conveying pipes 150 are connected one-to-one with the bottoms of the N receiving holes 131, and the N receiving holes 131 and their corresponding N conveying pipes 150 form the aforementioned N feeding channels.

[0042] like Figure 7 and Figure 8 As shown, the nailing device includes a mounting head 210, a mounting head 220, a conversion slide 230, and a slide base 240.

[0043] like Figure 9 As shown, the mounting head 210 has a through-hole accommodating space 211, which gives the mounting head 210 an inner wall. The mounting head 220 is formed by two C-shaped posts 221 interlocking. The upper end of each C-shaped post 221 is rotatably mounted on the inner wall of the mounting head 210. A spring 222 is provided between the outer wall of each C-shaped post 221 and the inner wall of the mounting head 210. The rotation axis of the C-shaped post 221 is perpendicular to the extension / retraction direction of the spring 222. It should be noted that the cross-section of the C-shaped post 221 is arc-shaped, resembling the letter C; therefore, it is referred to as a C-shaped post in this invention. The overall shape of the two C-shaped posts 221 after interlocking is cylindrical, as shown... Figure 7 and Figure 8 As shown, the external shape of the mounting head 220 is a combination of a cylinder and a cone, and the internal space of the cylinder is suitable for the rivet to pass through.

[0044] like Figure 7 and Figure 8 As shown, the conversion slide 230 is provided with stamping cylinders 231 and rivet inlets 232 arranged sequentially along its length. The rivet inlets 232 are connected to the end of the corresponding conveying pipe 150. It should be noted that, to avoid cluttered lines, Figure 1 The connection between each rivet inlet 232 and the end of the corresponding conveying pipe 150 is not shown in the diagram, but in reality, the rivet inlets 232 of the N rivet-driving devices are connected one-to-one with the ends of the conveying pipes 150 of the N feeding channels. It should be noted that one side of the mounting head 220, i.e. Figure 7 The right side of the mounting head 220 Figure 8 On the left side of the mounting head 220, a notch is provided from bottom to top. This notch is an avoidance notch created to accommodate the nailing target in one specific embodiment. In other embodiments of this invention, if the nailing target is suitable for the mounting head 220 without the notch to be moved entirely to the nailing position, then the notch is not required.

[0045] like Figure 7 , Figure 8 and Figure 9 As shown, the slide base 240 is adapted to slide the conversion slide 230 along the length direction, and the slide base 240 has a vertical through hole 241 inside. When the conversion slide 230 is driven to slide along the length direction, the rivet inlet 232 is aligned with the mounting head 220, or the stamping cylinder 231 is aligned with the mounting head 220.

[0046] It should be understood that when the two C-shaped posts 221 are tightly engaged, the size of the bottom opening of the mounting head 220 is smaller than the cross-sectional size of the rivet, at least smaller than the cross-sectional size of the rivet head, so that the rivet is clamped in the mounting head 220 before being stamped by the stamping cylinder 231.

[0047] Based on the structure of the rivet installation mechanism described above, the rivets on the feeding rack 110 enter the corresponding feeding grooves 121 one by one as the sliding block 120 slides. When the feeding groove 121 is aligned with the receiving hole 131, the rivets fall from the feeding groove into the receiving hole 131. When the feeding groove 121 is misaligned with the receiving hole 131, the top of the receiving hole 131 is blocked by the bottom of the sliding block 120. At this time, the air blowing device connected to the air inlet pipe 140 is activated to blow air, which can blow the rivets from the receiving hole 131 to the rivet inlet 232 of the rivet-driving device through the conveying pipe 150. When the rivet inlet 232 is aligned with the mounting head 220, the rivets fall into the mounting head 220. When the stamping cylinder 231 is aligned with the mounting head 220, the stamping cylinder is activated to drive the rivets into the rivet-driving target located below the rivet-driving device. When the stamping cylinder is not activated, the two C-shaped pillars 221 are tightly engaged under the elastic force of the spring 222, holding the rivet. When the stamping cylinder is activated to stamp, the rivet moves downward and squeezes the two C-shaped pillars 221 to both sides, causing the upper ends of the two C-shaped pillars 221 to rotate to both sides and the lower ends to separate, releasing the rivet.

[0048] In addition, such as Figure 2 , Figure 3 and Figure 4 As shown, the feeding assembly 100 may further include an electric cylinder 160, and the sliding block 120 is driven by the electric cylinder 160. The feeding assembly 100 may further include a base plate 170 located at the bottom of the receiving block 130, a side baffle 180 located on the side of the sliding block 120, and an upper cover plate 190 located on the upper part of the sliding block 120. Since the side baffle 180 is located between the sliding block 120 and the feeding rack 110, it has a through hole suitable for rivets to pass through.

[0049] like Figure 10 and Figure 11 As shown, the mounting assembly 200 may also include a platform frame 250, and the N nailing devices are fixed at different positions on the platform frame 250.

[0050] In one embodiment of this utility model, the platform frame 250 is height-adjustable to accommodate different nailing targets. For example... Figure 10 and Figure 11 As shown, the mounting assembly 200 may further include a lead screw 260, a lifting gear 270, a lead screw bearing seat 280, and a motor 290. One end of the lead screw 260 is fixed to one side of the platform frame 250; the lifting gear 270 is fixed to the lead screw 250 with the lead screw 260 as its pivot; the lead screw bearing seat 280 cooperates with the lead screw 260, suitable for the lead screw 260 to rotate and move up and down within it; the output shaft of the motor 290 is connected to the lifting gear 270 to drive the lifting gear 270 to rotate. The rotation of the lifting gear 270 can drive the lead screw 260 to rotate within the lead screw bearing seat 280, thereby realizing the up and down movement of the lead screw 260, and thus driving the platform frame 250 to rise and fall.

[0051] like Figure 1 and Figure 12 As shown, the rivet mounting mechanism may further include a housing 300 and a frame 400. The frame 400 is used to support and fix the feeding assembly 100 and the mounting assembly 200, and the housing 300 is used to accommodate the feeding assembly 100 and the mounting assembly 200. The aforementioned lead screw bearing seat 280 can be fixed to the frame 400, that is, the position of the lead screw bearing seat 280 is constant relative to the main frame of the rivet mounting mechanism.

[0052] In addition, such as Figure 12 As shown, the rivet mounting mechanism may also include peripheral auxiliary components such as a display control screen 500 and an electrical box 600.

[0053] In a preferred embodiment of this invention, N is greater than 1, meaning the rivet mounting mechanism can feed and nail through multiple channels, thus improving rivet mounting efficiency. The structures shown in the figures of this invention use an N of 8 as an example.

[0054] The rivet installation mechanism of this utility model can automatically install rivets by feeding them through a feeding assembly including N feeding channels and nailing them through an installation assembly including N nailing devices, which is convenient, efficient and reliable.
