Detailed Implementation

[0056] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0057] This utility model provides a fully automatic screw-locking device for assembling dual-crystal heat sinks. The device transports the heat sink fins along a predetermined direction via a conveying device 110, sequentially printing thermal grease, placing the crystal, and tightening the screws during the transport process. This achieves fully automatic assembly and fastening. Simultaneously, it can also trim and correct the crystal leads. The technical solution provided by this utility model enables fully automatic heat sink assembly, saving significant labor, reducing production costs, and improving production efficiency.

[0058] Specifically, such as Figure 1-10 As shown, a fully automatic dual-crystal screw-locking device for heat sinks includes a machine base 100, on which a conveying device 110 is mounted to transport heat sinks in a predetermined direction. Along the flow direction of the conveying device 110, the machine base 100 is equipped with: a grease-printing mechanism 200 and a crystal feeding and assembly mechanism 300. The grease-printing mechanism 200 is used to print grease onto the mounting surface of the heat sink, and includes a grease-holding container 210 and a printing assembly 220 for applying and printing the grease. The crystal feeding and assembly mechanism 300 includes two parallel crystals, each used to supply crystals, trim and correct the crystal leads, and then transfer them to the heat sink for screw-locking. The two crystal feeding assembly mechanisms 300 each include a feeding component 310, a cutting component 320, a transfer component 330, and a locking component 340. Specifically, the feeding component 310 includes a hopper 311 and a conveying channel 312 for crystals to flow out of the hopper 311. The cutting component 320 is used to cut the leads on the crystal. It is located at the outlet 3113 end of the conveying channel 312 and includes a cutting blade 321 and a cutting drive device 322 to drive the cutting blade 321 to perform the cutting action. The transfer component 330 is used to transfer the crystal to the heat sink conveyed by the conveying device 110. The locking component 340 is suspended above the conveying device 110 and is used to lock the crystal to the heat sink with screws. It includes an electric screwdriver 341.

[0059] During the processing of the heat sink, the heat sink is conveyed in a predetermined direction by a conveying device 110. In this embodiment, the conveying device 110 can be any existing technology capable of moving the heat sink. In this embodiment, a belt conveyor 110 is used to complete the conveying operation of the heat sink. When the heat sink is conveyed to the position opposite to the grease printing mechanism 200, the printing component 220 dips the grease in the glue box 210 and applies it to the heat sink. Then, the conveying device 110 continues to convey the grease-coated heat sink toward the crystal feeding and assembly mechanism 300, and performs crystal assembly and locking processing at the corresponding positions. In this embodiment, there are two crystal feeding and assembly mechanisms 300 arranged side by side, each used to assemble one crystal. That is, after the heat sink flows through the two crystal feeding and assembly mechanisms 300, two crystals are assembled on the heat sink, thereby... The assembly of the heat sink is completed. Specifically, the feeding assembly 310 holds and provides the crystals. The crystals are stored in the hopper 311 and flow along the conveying channel 312. During the flow, the cutter 321, driven by the cutting drive device 322, cuts and trims the crystal leads. The trimmed crystals are then transferred to the heat sink by the transfer device. The heat sink and crystals are then locked together with bolts by the electric screwdriver 341 on the locking assembly 340. The operation of the next crystal feeding assembly mechanism 300 is the same as described above and will not be repeated here. By using two crystal feeding assembly mechanisms 300, the heat sink can be assembled with two crystals and locked with bolts. At the same time, during the crystal feeding process, the length of the crystal leads can be trimmed by the cutting assembly to ensure that the lead length is standardized. In the entire processing process, the input of manual labor can be reduced, thereby reducing production costs and improving production efficiency.

[0060] In this embodiment, as Figure 2-3 As shown, the printing assembly 220 is positioned above the conveying device 110 and includes a first cylinder 221, a rotary cylinder 222, and a printing rod. Specifically, the rotary cylinder 222 is connected to the first cylinder 221 and moves back and forth vertically toward or away from the conveying device 110 under its drive. The middle part of the printing rod is connected to the rotary cylinder 222, and one end of the printing rod extends to the top of the heat sink on the conveying device 110, and the other end extends to the top of the glue box 210, and both ends are provided with a dotting element 223.

[0061] Meanwhile, the grease box 210 includes: a box body 211, a support member 213, a scraper 214, and a first drive motor 215. Specifically, the box body 211 is used to hold thermal grease, and a notch 212 is opened on one side wall of the box body 211 so that one side is an open structure; the support member 213 is rotatably set at the bottom of the box body 211 and carries the thermal grease; the scraper 214 is set inside the box body 211, and one end of it extends toward the support member 213, and there is a gap between it and the support member 213, which is used to scrape the thermal grease located on the support member 213; the first drive motor 215 is set below the box body 211 and is rotatably connected to the support member 213, which is used to drive the support member 213 to rotate around the axis inside the box body 211 and drive the thermal grease to rotate.

[0062] When it is necessary to print thermal grease on the heat sink, the thermal grease is placed inside the housing 211 and supported by the support member 213. At this time, driven by the rotary cylinder 222 and the first cylinder 221, one of the dotting members 223 extends into the housing 211 along the notch 212, thereby contacting the thermal grease and dotting it. Then, driven by the first cylinder 221 and the rotary cylinder 222, the dotting member 223 with thermal grease is moved towards the heat sink and the thermal grease is printed on the heat sink. The first cylinder 221 and the rotary cylinder 222 repeat the above actions, so that the two dotting members 223 can alternately complete the dotting and printing actions, thereby improving the efficiency of printing thermal grease. It is worth noting that the dotting component 223 cannot repeatedly dot the heat dissipation oil at the same position within the housing 211. Therefore, under the drive of the first drive motor 215, the support component 213 rotates so that the dotting component 223 can change the position of the heat dissipation oil to ensure that enough heat dissipation oil is dotted. At the same time, during the rotation of the support component 213, the scraper 214 scrapes the surface of the heat dissipation oil to ensure the flatness of the surface of the heat dissipation oil and ensures that the contact area between the dotting component 223 and the heat dissipation oil is large enough when the heat dissipation oil is being dotted, thus ensuring that a sufficient amount of oil is picked up.

[0063] In this embodiment, as Figure 4-10As shown, the feeding assembly 310 includes a vertically arranged conveying plate 313, a conveying channel 312 arranged on the conveying plate 313, and the conveying channel 312 is provided with an outlet 3121 for crystal pins to leak out. The conveying channel 312 includes a conveying section 3122 arranged in a vertical direction and an outlet section 3123 arranged in a horizontal direction below the conveying section 3122. A transition section 3124 with an arc structure is provided between the conveying section 3122 and the outlet section 3123. The hopper 311 is arranged above the conveying plate 313, and its outlet 3113 is connected to the upper opening of the conveying section 3122. During the crystal conveying process, after the crystal flows out of the outlet 3113 of the hopper 311, it is conveyed under the influence of gravity along the vertically arranged conveying section 3122, and gradually flows in the horizontally arranged outflow section 3123 under the guidance of the transition section 3124. It is worth noting that the cross-section of the conveying channel 312 is roughly "U" shaped, so that the main body of the crystal is confined inside the conveying channel 312, and the pins protrude from the protrusion section 3121, which facilitates the trimming and cutting of the pins by the cutting component 320.

[0064] In this embodiment, the hopper 311 includes a base plate 3111, a rotating component 3112, and a second drive motor 3115. The base plate 3111 is fixedly mounted on the conveying plate 313, and the outlet 3113 is located at a position corresponding to the bottom plate 3111 and the conveying section 3122. The rotating component 3112 is rotatably connected to the base plate 3111, and a plurality of spaced-apart and vertically arranged material pipes 3114 are arranged on the rotating component 3112 along the circumferential direction. Crystals are stacked and contained within the material pipes 3114, and a through groove is provided on the rotating component 3112 for the crystals to flow out of the material pipes 3114. The rotating component 3112 is located below the base plate 3111 and is connected to the rotating component 3112 for driving the rotating component 3112 to rotate around the axis, so that all the material pipes 3114 correspond to the outlet 3113 in sequence, allowing the crystals contained in the corresponding material pipes 3114 to flow out along the outlet 3113 toward the conveying channel 312. In other words, the crystals stored in the material tube 3114 flow downwards under the action of gravity. At the same time, when the second drive motor 3115 drives the rotating component 3112 to rotate, so that the through groove on the rotating component 3112 corresponds to the outlet 3113 on the bottom plate 3111, the crystals located in the material tube 3114 flow out of the outlet 3113 and flow into the conveying channel 312, where they are conveyed along the conveying channel 312.

[0065] In this embodiment, as Figure 7-8As shown, the cutting assembly 320 also includes a vertical plate 323, cutting blocks 324, and a transmission unit 325. Specifically, the cutting blocks 324 include a first cutting block 3241 and a second cutting block 3242 that are vertically opposed to each other. The two cutting blocks 324 are slidably connected to the vertical plate 323 in the vertical direction, forming cutters 321 that move closer or further apart. Corresponding surfaces of the two cutting blocks 324 are formed with mutually cooperating blades 3243. One end of the transmission unit 325 is connected to the cutting drive, and the other end is connected to the cutting drive device 322, used to drive the two cutting blocks 324 to move closer or further apart to complete the cutting operation. During the cutting process, the cutting drive device 322 drives the two cutting blocks 324 to move through the transmission unit 325, thereby cutting and trimming the pins extending along the protruding part 3121.

[0066] In this embodiment, the cutting drive device 322 is a cylinder, and the transmission unit 325 includes: a first transmission rod 3251, a second transmission rod 3254, and a connecting rod 3256. One end of the first transmission rod 3251 is fixedly connected to the first cutting block 3241 located on the upper side and is drively connected to the cutting drive device 322. The other end of the first transmission rod 3251 extends away from the first cutting block 3241 and is rotatably connected to a connecting block 3252. A connecting hole 3253 is formed on the connecting block 3252. The second transmission rod... The second transmission rod 3254 is arranged side by side with the first transmission rod 3251 on the lower side of the first transmission rod 3251. The middle part of the second transmission rod 3254 is rotatably connected to the vertical plate 323 via the pivot 3255. One end of the second transmission rod 3254 extends toward the second cutting block 3242 and is movably disposed on the second cutting block 3242. The other end extends away from the second cutting block 3242. One end of the connecting rod 3256 is rotatably connected to the end of the second transmission rod 3254 away from the second cutting block 3242. The other end of the connecting rod 3256 is slidably connected to the connecting hole 3253. In other words, when the cutting drive device 322 drives the first transmission rod 3251 to move downward, the first cutting block 3241 moves downward. At this time, the first transmission rod 3251 drives the second transmission rod 3254 to swing around the pivot 3255 through the connecting rod 3256. Specifically, the end of the second transmission rod 3254 connected to the connecting rod 3256 swings downward, and the end movably connected to the second cutting block 3242 tilts upward, thereby pushing the second cutting block 3242 to move upward. With the cooperation of the first cutting block 3241, the two blades 3243 cut the crystal pins placed between the first cutting block 3241 and the second cutting block 3242, completing the trimming action.

[0067] In this embodiment, as Figure 4 , 9As shown in Figure -10, a gripping position 3125 is provided at the end of the outflow section 3123, which allows the crystal to leak out of the outflow section 3123. Meanwhile, the transfer assembly 330 includes a second cylinder 331, a third cylinder 332, and a clamping cylinder 333. Specifically, the third cylinder 332 is vertically disposed on the second cylinder 331 and is driven by it to reciprocate in the direction of the conveying device 110. The clamping cylinder 333 is fixedly mounted on the third cylinder 332 and is driven by the third cylinder 332 to reciprocate in the vertical direction. The clamping cylinder 333 is provided with a gripper 334 facing the gripping position 3125.

[0068] To facilitate the gripper 334 in gripping the crystal at the gripping position 3125, the transfer assembly 330 also includes a lifting cylinder 335. The lifting cylinder 335 is located below the gripping position 3125 and is connected to a push rod. The outlet 3123 is provided with a hole for the push rod to extend out, so as to lift the crystal upward at the gripping position.

[0069] During the process of gripping and transferring the crystal, the gripper 334 moves back and forth along the gripping position 3125 and the conveying device 110 under the drive of the third cylinder 332 and the second cylinder 331, so that the crystal located at the gripping position 3125 can be gripped and placed on the heat sink carried by the conveying device 110. At this time, the clamping cylinder 333 grips the crystal located at the gripping position 3125, and the lifting cylinder 335 drives the top rod (not shown in the figure) to rise, thereby lifting the crystal in the gripping position 3125, so as to facilitate the gripping cylinder 333 to grip and transfer.
