Therefore, there is an urgent need for an automatic riveting feeding device, which can automatically perform the feeding and riveting of the heat sink, and reduce the risk of riveting operation.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. It should be apparent that the embodiments described in this application are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments in the present application, are within the scope of protection of the present application.

In an implementation embodiment, referring to fig. 2 to fig. 6 together, an automatic rivet pressing feeding device may include at least a lateral moving mechanism 21 and two positioning jigs 22. Wherein, two positioning jigs 22 are connected at the moving end of the transverse moving mechanism 21, and the two positioning jigs 22 are arranged at intervals.

Thus, the transverse moving mechanism 21 is used for driving the two positioning jigs 22 to switch between the upper and lower material levels and the riveting position. For example, the two positioning jigs 22 are divided into a first positioning jig and a second positioning jig, and when the first positioning jig is located at the upper and lower material levels, the second positioning jig is located at the riveting position, and vice versa.

In other words, when any one positioning jig 22 of the two positioning jigs 22 is located at the riveting position, the other positioning jig can be subjected to loading and unloading operations, so that the production efficiency is improved. In addition, the positioning jig 22 is adopted to clamp the radiating fins to move to the riveting position, the radiating fins do not need to be sent by hands, and the safety of riveting operation is improved.

As to the specific structure of the positioning fixture 22, please refer to fig. 5 to 6, in an implementation embodiment, the positioning fixture 22 includes a base 221 and a positioning seat 222, wherein the positioning seat 222 is connected to the base 221 by a guide pillar 223 in a vertical sliding manner, and an elastic element 224 is sleeved on the guide pillar 223, the elastic element 224 is used for floating on the base 221 when the positioning seat 222 is not under pressure, and when the riveting device presses down the heat sink on the positioning seat 222, the positioning seat 222 and the heat sink thereon move down to contact and rivet with the legs, so as to realize the riveting operation. The guide post 223 is used for guiding the positioning seat 222 when sliding up and down.

It should be noted that the top surface of the positioning socket 222 has a supporting plate 2221 protruding outward, and the supporting plate 2221 supports the heat sink together with the top surface of the positioning socket 222, where the purpose of protruding outward is to make the protrusion at the bottom of the heat sink float outward, so as to facilitate the contact and riveting with the clip. Meanwhile, the support plate 2221 is also required to have a through groove 2222 therein so as to give way to the protruding portion of the heat sink.

In practical applications, the elastic element 224 may be a spring, or other elastic barrel. The number of the through slots 2222 is two, and when the heat sink 11 is positioned on the positioning fixture 22, the bottom surface protrusions of the heat sink 11 are respectively located in the two through slots 2222. In addition, in order to rivet the two protruding riveting pins at the bottom of the heat dissipation fin at one time, the transverse moving mechanism 21 may adopt a servo linear module, and sequentially move the bottom surface of the heat dissipation fin to the upper side of the pins according to the protruding position of the bottom surface of the heat dissipation fin.

To achieve the positioning of the heat sink by the positioning socket 222. In an implementation embodiment, a first positioning block 225 is fixed at each end of the positioning base 222, a second positioning block 226 is fixed on the supporting plate 2221, and a positioning adjustment component 227 is disposed on the positioning base 222, wherein the positioning adjustment component 227 is disposed opposite to the second positioning block 226.

Thus, when the heat sink is placed on the positioning base 222, two ends of the heat sink are positioned by the two first positioning blocks 225. One side of the heat sink is located by a second locating block 226, and the other side of the heat sink is located and pressed by a locating and adjusting component 227.

As to the specific structure of positioning adjustment assembly 227, a third positioning block 2271 and a locking screw 2272 may be included. The third positioning block 2271 has an elliptical hole 2273, and a connection line of two circle centers of the elliptical hole 2273 is perpendicular to the second positioning block 226. The locking screw 2272 passes through the elliptical hole 2273 to be connected with the positioning socket 222. Like this, can realize adjusting third locating piece 2271 and lock to corresponding position department, also can be after the fin is placed on positioning seat 222, through the opposite side butt of removing third locating piece 2271 with the fin, then lock third locating piece 2271.

To facilitate the connection of the positioning jig 22 to the lateral movement mechanism 21. A connection block 2211 may be provided on a side of the base 221 away from the support plate 2221. Thus, the base 221 is connected to the moving end of the lateral moving mechanism 21 through the connecting block 2211.

Further, riveting automatic feeding device still includes atress seat 23, wherein, is provided with spout 231 on the atress seat 23. The bottom surface of base 221 is provided with slider 2212, and slider 2212 sliding connection is in spout 231 to can shift the pressure of riveting to on the atress seat, thereby improve whole loading attachment's life.

In an implementation manner, referring to fig. 7, the automatic rivet pressing feeding device further includes a box body 24. The lateral movement mechanism 21 is accommodated in the case body 24, and the case body 24 has a discharge chute 241 at the top end. Therefore, the space can be effectively utilized, and the occupied area of the equipment is reduced. Meanwhile, the box body 24 can also reduce external dust from entering the transverse moving mechanism 21, and the service life of the transverse moving mechanism 21 is prolonged. And, blowing groove 241 can conveniently be placed the product after waiting the fin of riveting and having riveted, and it is more convenient to use.

Therefore, the technical scheme that this application provided can drive two positioning jig through adopting lateral shifting mechanism and go on unloading in turn automatically to the fin, need not the manual work and places the fin in riveting machine below, reduces the danger of riveting operation to the mode of going up the unloading in turn can go on unloading, improvement production efficiency at the in-process of riveting. Simultaneously, positioning jig adopts base and positioning seat to the positioning seat floats and sets up on the base, like this, at the riveting in-process, the fin is pressed the back and is contacted the riveting with the foot son, and rises along with the positioning seat together after the riveting, and the unloading after the equipment of being convenient for, convenient operation is swift.

Furthermore, can also be provided with the atress seat to make the base slide on the atress seat, thereby when the fin riveting, can shift the riveting atress to on the atress seat, thereby improve whole loading attachment's life.
