[0031] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below, in which only the parts related to the embodiment of the present invention are shown.

[0032] like Figure 1The invention relates to a heat sink rivet device, comprising a heat sink operating mechanism 1, a rivet directional movement mechanism 2, a riveting mechanism 3, and a main control module 4. Specifically, the riveting mechanism 3 is located above the heat sink operating mechanism 1 and is fixedly connected to the rivet directional movement mechanism 2. The heat sink operating mechanism 1, the rivet directional movement mechanism 2, and the riveting mechanism 3 are all electrically connected to the main control module 4. The heat sink operating mechanism 1 sequentially transfers multiple heat sinks to the bottom of the riveting mechanism 3, the rivet directional movement mechanism 2 transfers multiple rivets to the riveting mechanism 3, and the riveting mechanism 3 punches at least one rivet on each heat sink. The main control module 4 is provided with a display screen (the display screen can be a touch screen), through which the feeding time of the heat sink operating mechanism 1, the feeding time of the rivet directional movement mechanism 2, and the riveting time of the riveting mechanism 3 can be set. For example, the feeding and nail feeding can be set to be performed simultaneously, and the riveting can be performed last, or the time interval between feeding, nail feeding, and riveting is less than 0.1 second, thereby achieving a fully automatic and fast riveting effect. The heat sink operating mechanism 1 and the rivet directional movement mechanism 2 are both fixedly connected to the workbench 8. The riveting mechanism 3 is fixedly connected to the workbench 8 via a fixing device. The fixing method is not limited to bolting, welding, or clamping. In this embodiment, the number of rivets used for each heat sink is preferably two. It should be noted that the heat sink must be pre-punched before riveting to ensure the integrity of the heat sink.

[0033] like Figure 2As shown, the heat sink operation mechanism 1 includes a first assembly line 10, a second assembly line 11, and a steering adjustment structure 12. The steering adjustment structure 12 is connected to both the first assembly line 10 and the second assembly line 11. The first assembly line 10, the steering adjustment structure 12, and the second assembly line 11 are arranged in a Z shape. The first assembly line 10 and the second assembly line 11 are parallel to each other, and the steering adjustment structure 12 is perpendicular to both the first assembly line 10 and the second assembly line 11. The first assembly line 10 is used to move multiple heat sinks to the steering adjustment structure 12 in sequence. The steering adjustment structure 12 is used to adjust the position of each heat sink transferred from the first assembly line 10 in sequence and move the adjusted heat sinks to the second assembly line 11 in sequence. The second assembly line 11 is used to move the multiple heat sinks transferred from the steering adjustment structure 12 in sequence to the bottom of the riveting mechanism 3. Specifically, the second assembly line 11 includes a first conveying track 110, a traction assembly 111, and a drive module 112. The traction assembly 111 is fixedly connected to the drive module 112, and the fixed connection method includes but is not limited to screw connection, welding or fixing device connection. The traction assembly 111 is adjacent to the first conveying track 110, that is, the traction assembly 111 does not contact the first conveying track 110 during the entire process of traction of the heat sink, and a relatively small gap is maintained between them, so that the traction assembly 111 does not generate friction with the first conveying track 110 during the movement, thereby improving the traction efficiency and protecting the traction assembly 111. Furthermore, the first conveying track 110 is provided with at least one rivet groove 1100. In this embodiment, the number of rivet grooves 1100 is preferably 2. The rivet groove 1100 provides space for the rivet to move downward under force, thereby ensuring the integrity of the rivet. Furthermore, the traction assembly 111 includes a connecting plate 1110 and a plurality of forks 1111. The plurality of forks 1111 are all fixedly connected to the connecting plate 1110, and the fixed connection includes but is not limited to screw connection, welding or an integrated structure. Each fork 1111 is provided with two fork arms, and the number of fork members 1111 is preferably four. Furthermore, the driving module 112 includes a first driving module 1120 and a second driving module 1121 fixedly connected to the first driving module 1120. The second driving module 1121 is fixedly connected to the connecting plate 1110, and its connection method includes but is not limited to screw connection, welding or fixing device connection. The fork arm of each fork member 1111 contacts a heat sink through the second driving module 1121, and drives the heat sink to move through the first driving module 1120. It should be noted that the distance between the two fork arms of each fork member 1111 is slightly larger than the left and right widths of the heat sink, so that the fork arms can easily contact and separate from the heat sink.Specifically, the second drive module 1121 is capable of driving the forks 1111 to reciprocate back and forth perpendicularly to the first conveyor track 110. When moving forward (approaching the first conveyor track), each heat sink is positioned between the two fork arms of each fork 1111. When moving backward (away from the first conveyor track), the two fork arms of each fork 1111 move away from each heat sink. The first drive module 1120 is capable of driving the forks 1111 and the second drive module 1121 to reciprocate left and right parallel to the first conveyor track 110. Before moving to the right (moving to the riveting mechanism), the second drive module 1121 has moved forward. At this time, each heat sink has been placed in the two fork arms of each fork 1111. When moving to the right, the fork 1111 drives multiple heat sinks to move toward the riveting mechanism 3; before moving to the left, the second drive module 1121 has moved backward. At this time, the two fork arms of each fork 1111 have been removed from each heat sink, and multiple fork members 1111 return to their original position under the drive of the first drive module 1120. Further, the steering adjustment structure 12 includes a steering mechanism 120 and an adjusting member 121. Specifically, the steering mechanism 120 and the adjusting member 121 are clearance-matched, and the adjusting member 121 is fixedly connected to the first conveying track 110 of the first assembly line 10 and the second assembly line 11 (including but not limited to screw connection). The steering mechanism 120 includes a third drive module 1200 and a push plate 1201 fixedly connected to the third drive module 1200.

[0034] like Figure 3As shown, the adjustment member 121 includes a cover plate 1210 and a base 1211 fixedly connected to the cover plate 1210. A bump 12100 is provided on the bottom edge of the cover plate, and the base 1211 includes a first connector 12110, a second connector 12111, a third connector 12112, and a fourth connector 12113, all of which are fixedly connected to the cover plate 1210. Specifically, the first connector 12110, the second connector 12111, the third connector 12112, the fourth connector 12113, and the cover plate 1210 form a cavity with three openings that can only accommodate one heat sink. It should be noted that the first connector 12110 and the fourth connector 12113 are identical in shape and size, the second connector 12111 and the third connector 12112 are identical in shape and size, and the four connectors are of the same height, which is greater than the height of one heat sink and less than the height of two heat sinks. Moreover, the dimensions of the aforementioned opening and cavity need to be determined based on the size and movement direction of the heat sink. In short, it is necessary to ensure that the cavity can accommodate one heat sink. Furthermore, the first connector 12110, the second connector 12111, and the cover plate 1210 form a first opening, the second connector 12111, the third connector 12112, and the cover plate 1210 form a second opening, and the fourth connector 12113, the first connector 12110, and the cover plate 1210 form a third opening. The protrusion 12100 abuts against the base 1211, the third connector 12112, and the fourth connector 12113, and is opposite the first opening. The first opening corresponds to the first assembly line 10, that is, the first opening is aligned with the heat sink outlet of the first assembly line 10, and the heat sink directly enters the first opening after leaving the first assembly line 10. There may be multiple overlaps of the multiple heat sinks transported on the first assembly line 10, and multiple heat sinks may also be in an oblique state, that is, the two opposite sides of the heat sink are not parallel to the horizontal direction of the first assembly line 10 or perpendicular to the vertical direction, which will affect the subsequent processing (such as riveting), and thus, a positioning structure for the heat sink needs to be set. Therefore, the first opening is used for a single heat sink on the first assembly line 10 to enter the cavity and separate the overlapping heat sinks. The second opening is clearance-matched with the push plate 1201, and the push plate 1201 is used to push the heat sink stationary in the cavity to the first conveying track 110. The bump 12100 is used to block the movement of the heat sink and adjust the position of the heat sink under the action of resistance. Specifically, after a single heat sink enters the cavity through the first opening, it abuts against the protrusion 12100 and remains perpendicular to the protrusion 12100 under the extrusion of multiple subsequent heat sinks. At the same time, the protrusion 12100 generates resistance due to the extrusion. When the resistance reaches a certain value (such as the resistance value when two heat sinks are squeezed together), the first assembly line 10 can be suspended. The protrusion 12100 is perpendicular to the moving surface of the first assembly line 10 and also perpendicular to the track surface of the first conveying track 110, thereby achieving the purpose of adjusting the position of the heat sink.When the first assembly line 10 is paused, the push plate 1201, driven by the third drive module 1200, can enter the adjustment member 121 from the second opening and push the heat sink stationary between the first opening and the protrusion 12100 from the third opening toward the first conveyor track 110. After the heat sink leaves the adjustment member 121, the resistance disappears, and the first assembly line 10 continues to operate, driving the other heat sinks toward the adjustment member 121. Furthermore, the adjustment member 121 is fixedly connected to the first assembly line 10 and the first conveyor track 110 via a base 1211. The fixed connection method can be, but is not limited to, bolt connection or clamping.

[0035] like Figure 4-6As shown, the rivet directional movement mechanism 2 includes a vibration disk 20 (rivet directional movement mechanism), and a nail feeding mechanism 21 (rivet counting and detection mechanism) connected to the vibration disk 20 and the riveting mechanism 3. Specifically, the vibration disk 20 is provided with a discharge track 200, and the vibration disk 20 is used to adjust the direction of a single rivet on the discharge track 200, so that the rivet head is arranged in the front and the nail tip is placed in the back, and is moved out of the discharge track 200 in sequence under the vibration of the vibration disk 20. The vibration disk 20 is an existing technology or a proprietary technology and will not be described in detail here. The nail feeding mechanism 21 includes a second conveying track 210 and a needle pushing mechanism 211. The second conveying track 210 is provided with a plurality of air blowing pipes 2100 (the specific number depends on the length of the second conveying track), and the air blowing pipe 2100 is preferably a metal pipe. The air blowing pipe 2100 is connected to the first air blowing device, and the first air blowing device is electrically connected to the main control module 4. The needle pushing mechanism 211 includes a fourth driving module 2110, a reversing structure 2111 and a sliding block 2112. The sliding block 2112 is provided with at least one accommodating hole (first through hole). The reversing structure 2111 includes at least one first detector 21110, at least one blowing hole 21111 (second through hole), a slot 21112, at least one nail outlet hole 21113 (fourth through hole) and at least one nail feed hole 21114 (third through hole). It should be noted that the number of the needle hole 21101, the first detector 21110, the blowing hole 21111, the nail outlet hole 21113 and the nail feed hole 21114 is equal, and in this embodiment, they are preferably 2; the second conveying track 210 is provided with a shell device at the extension of the discharge track 200, and there is a small gap between the shell device and the discharge track 200. The provision of the gap is conducive to increasing the wind speed of the first blowing device, so that the rivet continues to run on the track, and also ensures that the rivet is running quickly. The air blowing hole 21111 is connected to the second air blowing device through a connecting pipe, and the second air blowing device is electrically connected to the main control module 4. The sliding block 2112 is fixedly connected to the fourth driving module 2110 (not limited to screw connection), and is clearance-matched with the slot body 21112. The air blowing hole 21111 corresponds to the nail hole 21113 (that is, the two are on the same horizontal line) and are isolated by the slot body 21112. The nail hole 21113 is connected to the riveting device 30 through the tube body. The tube body is preferably a transparent plastic tube to facilitate observation of the state of the rivet in it. Furthermore, the nail entry hole 21114 is connected to the second conveying track 210. When the fourth driving module 2110 is closed, the accommodating hole corresponds to the nail entry hole 21114 (that is, the two are connected). When the fourth driving module 2110 is started, the accommodating hole corresponds to the nail exit hole 21113. That is, under the action of the airflow transmitted by the blowing pipe 2100, the plurality of rivets are blown into the receiving holes from the second conveying track 210 in sequence.The first detector 21110 is used to detect whether a rivet is present in the receiving hole. If so, when the rivet enters the receiving hole, it sends a signal to the main control module 4 to activate the fourth drive module 2110. The fourth drive module 2110 drives the sliding block 2112 to move to a position corresponding to the receiving hole and the nail outlet hole 21113. The main control module 4 controls the second blowing device of the air blowing hole 21111 to start blowing air, blowing the rivet from the receiving hole into the tube body, and the rivet enters the riveting device 30. It should be noted that the discharge track 200, the receiving hole, the nail outlet hole 21113, and the nail inlet hole 21114 can only accommodate one rivet. Moreover, the number of the first detector 21110, the discharge track 200, the receiving hole, the nail outlet hole 21113, and the nail inlet hole 21114 is consistent with the number of rivets riveted on the heat sink, preferably two in this case. The first detector 21110 is a detection electric eye, which is a prior art and will not be described in detail here. In addition, the reversing structure 2111 is also connected to a counter, which starts counting and displays the number of rivets after the rivets are blown into the rivet holes 21113. The counter is a prior art.

[0036] Further Figure 4 As shown, the riveting mechanism 3 includes a riveting device 30 fixedly connected to the pin pushing mechanism 211 (including but not limited to welding or screw connection), and a riveting base 31 connected to the nail hole 21113. Specifically, the riveting device 30 is movably connected to the riveting base 31, the riveting device 30 is provided with at least one needle body 300, and the riveting base 31 is provided with a needle hole 310 matching the needle body 300, and a pipe body joint 311 connected to the needle hole 310 and used to connect the pipe body. In this embodiment, the needle body 300, the needle hole 310, and the number of rivets riveted on the heat sink are consistent, and are preferably 2 here. Further, the riveting base 31 is arranged above the first conveying track 110, and the needle hole 310 is opposite to the rivet groove 1100. The riveting device 30 is a prior art and will not be described in detail here.

[0037] like Figure 2 、 Figure 7As shown, the heat sink rivet device of this embodiment also includes a second detector 5 and a sorting device 6, both connected to the main control module 4. The sorting device 6 is disposed at one end of the first conveyor track 110. The sorting device 6 includes a first sorting slot 60, a second sorting slot 61, and a fifth drive module 62 connected to the main control module 4. Specifically, the first sorting slot 60 and the second sorting slot 61 are integrally structured, and the fifth drive module 62 is fixedly connected to the first sorting slot 60. The second detector 5 is used to detect whether there is a heat sink beneath the riveting base 31 (the riveting mechanism 3 can only be activated if a heat sink is present) and whether there are rivets on the heat sink. Based on the detection results of the second detector 5, the sorting device 6 is used to sort heat sinks with rivets from those without rivets. Heat sinks with rivets are transported from the first conveyor track 110 to the first sorting trough 60. For heat sinks without rivets, the main control module 4 controls the fifth drive module 62 to drive the first sorting trough 60 away from the first conveyor track 110, and these heat sinks are transported from the first conveyor track 110 to the second sorting trough 61. It should be noted that the second detector 5 has the same number of rivets as the number of rivets riveted on the heat sink, preferably two. The second detector 5 is an infrared detector, which is conventional technology and will not be described in detail here.

[0038] like Figure 8 As shown, the heat sink rivet device of this embodiment also includes a positioning and punching mechanism 7 connected to the first conveying track 110. Specifically, the positioning and punching mechanism 7 includes at least one limiting structure 70, at least one lifting structure 71, a sixth drive module 72 and a connecting member 73. The limiting structure 70 and the lifting structure 71 are movably connected through a rotating shaft, and the limiting structure 70 and the sixth drive module 72 are both fixedly connected through a connecting member 73 (the fixed connection method is not limited to screw connection), the limiting structure 70 is connected to the lifting structure 71 and the sixth drive module 72, and a hollow structure for embedding the limiting structure 70 is provided in the first conveying track 110, and a hole structure for embedding the lifting structure 71 is provided in the rivet groove 1100, and the hole structure is opposite to the pinhole 310. Under the drive of the sixth drive module 72, the limiting structure 70 is used to lift the lifting structure 71 from the hole structure and push the heat sink toward the riveting base 31. This further stabilizes the heat sink during riveting and enhances the riveting effect. After the rivet is riveted on the heat sink, the sixth drive module 72 drives the limiting structure 70 to return to its original position. In this embodiment, the limiting structure 70 and the lifting structure 71 have the same number of rivets as the heat sink, that is, preferably two.

[0039] Preferably, the first drive module 1120, the second drive module 1121, the third drive module 1200, the fourth drive module 2110, the fifth drive module 62, and the sixth drive module 72 are all servo electric cylinders or servo motors. Furthermore, the main control module 4 is electrically connected to the first assembly line 10, the first drive module 1120, the second drive module 1121, the third drive module 1200, the fourth drive module 2110, the fifth drive module 62, the sixth drive module 72, the vibration plate 20, the pin pushing mechanism 211, the first detector 21110, and the second detector 5. The heat sink operation mechanism 1, the rivet directional movement mechanism 2, the riveting mechanism 3, the main control module 4, and the fifth drive module 62 are all fixedly connected to the workbench 8. The vibration plate 20 and the nail feeding mechanism 21 are fixedly connected to the workbench 8 by fixing devices, and the connection methods include but are not limited to welding or screw connection. Furthermore, the first assembly line 10 is a belt assembly line or a drum assembly line, and any equipment that can be used for blowing in the prior art can be used as the first blowing device and the second blowing device of this embodiment.

[0040] A specific implementation method is as follows: initially, the forks 1111 on both sides of the four traction components 111 are aligned with the third opening 1213 and the riveting base 31 respectively. Before riveting, the two forks 1111 in the traction component 111 are placed on the positions corresponding to the first conveying track 110, respectively, with a heat sink (of course, it is not necessary to place them. If not, the traction component 111 needs to move three times to move the first heat sink to the bottom of the riveting base 31). After the above steps are completed, the working connection time of the heat sink operation mechanism 1, the rivet directional movement mechanism 2 and the riveting mechanism 3 are set through the display screen of the main control module 4. After the setting is completed, multiple heat sinks are placed on the first assembly line 10, multiple rivets are placed in the vibration disk 20, and finally started by one button through the main control module 4. After startup, the vibration plate 20 and the first assembly line 10 begin operating synchronously. Multiple heat sinks enter the first opening in sequence and adjust their positions by abutting against the bump 12100. When multiple heat sinks are squeezed together on the first assembly line 10 (for example, two heat sinks), the first assembly line 10 pauses. The pause signal is received by the main control module 4, which activates the third drive module 1200 to drive the push plate 1201 to push the heat sink stationary between the first opening and the bump 12100 toward the first conveyor track 110. After the heat sink is pushed in (resistance disappears), the first assembly line 10 begins to continue conveying the heat sink, driving the other heat sinks toward the bump 12100. At this time, the second drive module 1121 moves forward within the time set by the main control module 4, so that the heat sink pushed into the first conveying track 110 is located between the two fork arms of the leftmost fork 1111 in the traction assembly 111, and the first drive module 1120 is started within the set time to move the heat sink to the right by a unit distance (the distance is the length of a fork); at this time, the rightmost fork 1111 of the traction assembly 111 is located between the riveting base 31 and the sorting device 6, and the second detector 5 detects that there is a heat sink under the riveting base 31 (at this time, the positioning and stamping mechanism pushes the heat sink to be riveted toward the riveting base 31), and transmits the signal to the main control module 4. The main control module 4 waits for the signal feedback of the first detector 21110 (the heat sink and the rivet can arrive at the riveting base at the same time after being set up). The first detector 21110 starts to detect whether there is a rivet waiting to enter the nail delivery tube 213 in the push-pin mechanism 211. If so, the signal is transmitted to the main control module 4. The main control module 4 starts the push-pin mechanism 211 to send the rivet into the pinhole 310 through the tube body and count (only when the heat sink and the rivet are in place at the same time, the counting and riveting are started). After the rivet is in place, the main control module 4 starts the riveting device 30 to rivet two rivets on the heat sink to be riveted. After the riveting is completed, the second detector 5 detects whether there are two intact rivets on the heat sink to be riveted (such as whether they are of the same length and whether there are two rivets). If the two rivets are inconsistent, it means that the rivet is defective. If the number of rivets is inconsistent, it means that the heat sink is defective, such as the heat sink is not pre-punched.In these two cases, the main control module 4 starts the fifth drive module 63 and moves the first sorting slot 60 away from the track opening of the first conveying track 110. Thereafter, the main control module 4 controls the second drive module 1121 and the first drive module 1120 to move backward and left successively, that is, the traction component 111 returns to the initial position and continues to move the second heat sink to be riveted. When the second heat sink to be riveted moves below the riveting base 31, the riveted heat sink (the first heat sink to be riveted) is located between the riveting base 31 and the sorting device 6. When the third heat sink to be riveted is moved to the riveting base 31, the riveted heat sink (the first heat sink to be riveted) is pushed out of the first conveying track 110 by the side wall of the fork 1111 on the rightmost side of the traction component 111 and enters the first sorting slot 60 or the second sorting slot 61. Thus, a complete riveting process is completed, and the riveting process will be repeated in sequence to achieve automatic riveting.

[0041] In summary, the heat sink rivet device of the present invention can standardize the fastening of rivets to heat sinks. The rivets on the heat sink can be more conveniently combined with other components, making it adaptable to large-scale processing procedures and greatly improving the processing efficiency and effectiveness of the heat sink. This riveting mechanism has a high degree of automation and high riveting efficiency, effectively protecting the integrity of the heat sink during the riveting process.
