[0034] Through the arrangement of the above structure, firstly, the electric cylinder 44 is extended to make the suction plate 46 fit on the top of the heat sink; then the double-headed motor 47 drives the clamping screws 471 on both sides to rotate in opposite directions, so that the clamping plates 472 on both sides approach the heat sink at the same time, and finally the heat sink is clamped and fixed; then the servo motor 41 drives the transfer screw 4 to rotate, so that the sliding block 42 slides along the transfer screw 4 toward the second conveyor belt 2, thereby driving the heat sink to move to the second conveyor belt 2, so as to transfer the heat sink to the second conveyor belt 2, thereby completing the self-transfer operation and effectively improving the processing efficiency.

[0036] Through the arrangement of the above-mentioned structure, during the downward movement of the flow limiting box 45, the compression ring 452 will be compressed into the air pressure chamber 451, and the compressed gas in the air pressure chamber 451 will enter the adsorption plate 46 along the sealing ring 454 and the air guide pipe 456, and then be discharged outward from the bottom of the adsorption plate 46, thereby generating a downward moving airflow effect on the top of the heat sink, and under the wrapping effect of the flow limiting box 45, a blowing effect can only be generated in a smaller area where the heat sink is located, thereby achieving a collecting effect, effectively blowing away the dust and impurities attached to the heat sink, and improving the cleanliness of the heat sink; then the electric cylinder 44 drives the flow limiting box 45 to retract, and under the rebound effect of the first spring 453, the sealing ring 454 will be reset and moved downward, and at this time, the port of the adsorption plate 46 is attached to the top of the heat sink and blocked, so a suction effect will be generated in the adsorption plate 46, thereby auxiliary fixing the heat sink from the top, effectively improving the stability of the heat sink during transportation.

[0037] Reference Figure 3 , Figure 6-Figure 8, wherein the cleaning component includes an air compression groove 5, which is opened in the mounting plate 43, and an air guide rod 51 is rotatably connected in the air compression groove 5, and the bottom end of the air guide rod 51 passes through the flow limiting box 45, and a first magnetic plate 52 is fixedly connected to the air guide rod 51 in the air compression groove 5, and a second magnetic plate 53 is slidably connected in the air compression groove 5, and a second spring 54 is fixedly connected between the side wall of the second magnetic plate 53 and the air compression groove 5, and the first magnetic plate 52 and the second magnetic plate 53 repel each other magnetically, and an air guide ring 55 is rotatably connected to the air guide rod 51, and the top of the air guide ring 55 is fixedly connected to the bottom of the mounting plate 43, and the air guide ring 55 is communicated with the inner cavity of the air guide rod 51, and an air filling tube 551 is fixedly connected to the outer wall of the air guide ring 55, and the air filling tube 551 The other end is connected to the inner cavity of the compressed air tank 5, and a one-way valve is provided in the inflation tube 551; the air guide rod 51 is divided into two sections, the upper and lower sections, the bottom end of the upper air guide rod 51 is fixedly connected to a cross plug box 511, the top of the outer wall of the lower air guide rod 51 is fixedly connected to a cross plug block 512, and the cross plug block 512 is sealed and plugged into the cross plug box 511; an external gear 513 is fixedly connected to the outer wall of the lower air guide rod 51, a fixed rack 56 is fixedly connected between the inner walls of the transfer frame 3, the external gear 513 and the fixed rack 56 are meshingly connected, a linkage gear 57 is fixedly connected to the outer wall of the adsorption plate 46, and an internal gear 514 is fixedly connected to the bottom end of the lower air guide rod 51, and the internal gear 514 and the linkage gear 57 are meshingly connected.

[0038] It should be noted that the one-way valve in the inflation tube 551 can only allow the airflow in the compressed air tank 5 to be transported to the flow limiting box 45; the plug-in cooperation between the cross plug block 512 and the cross plug box 511 can realize the engagement of the external gear 513 and the fixed rack 56 without delaying the lifting and lowering of the flow limiting box 45.

[0039] Through the arrangement of the above structure, when the electric cylinder 44 retracts, the cross plug block 512 will be plugged into the cross plug box 511. At this time, the external gear 513 and the fixed rack 56 are in a meshing state. Then the servo motor 41 drives the transfer screw 4 to rotate, so that the sliding block 42 slides along the transfer screw 4 toward the second conveyor belt 2, thereby driving the heat sink to move toward the second conveyor belt 2. At the same time, the meshing relationship between the external gear 513 and the fixed rack 56 will synchronously drive the two sections of the air guide tube 456 to rotate. In the process of rotation of the air guide tube 456, the repulsive effect of the first magnetic plate 52 and the second magnetic plate 53 will be used. The second magnetic plate 53 slides toward the side of the compressed second spring 54, thereby squeezing the gas in the compressed air groove 5 and opening the one-way valve in the inflation tube 551, so that the air flow blows toward the heat sink along the inflation tube 551, the air guide ring 55 and the air guide rod 51. At the same time, by utilizing the meshing relationship between the internal gear 514 and the linkage gear 57, when the air guide rod 51 rotates, the adsorption plate 46 is also driven to rotate synchronously, thereby driving the heat sink to rotate as a whole, and the blowing end position of the air guide rod 51 remains unchanged, so that the heat sink can be fully cleaned, which effectively improves the cleaning effect and ensures the quality of subsequent heat sink processing.

[0040] Reference Figure 5 An air inlet pipe 6 is fixed on the side wall of the compressed air groove 5 and connected thereto, an air flow groove 421 is provided on the sliding block 42, the other end of the air inlet pipe 6 is connected to the inner cavity of the air flow groove 421, and a one-way valve is arranged in the air inlet pipe 6.

[0041] It should be noted that the one-way valve in the air intake pipe 6 can only allow the external airflow to pass through the air flow groove 421 and the air intake pipe 6 to replenish the child's compressed air tank 5.

[0042] Through the arrangement of the above-mentioned structure, when the first magnetic plate 52 and the second magnetic plate 53 are separated from the repulsive area, the rebound effect of the second spring 54 will generate suction in the compressed air groove 5, so that the airflow passes through the airflow groove 421 and the air inlet pipe 6 to enter the compressed air groove 5 for replenishment, thereby ensuring continuous blowing and cleaning effect. At the same time, in the process of the airflow passing through the airflow groove 421, the heat generated by the threaded rotation between the transfer screw 4 and the sliding block 42 will be taken away, thereby effectively reducing the friction loss between the two and improving the durability of the two.

[0043] Reference Figure 3-Figure 5, wherein a flat pressure hole 457 is opened at the top of the air pressure bin 451, a limiting slide bar 7 is fixedly connected to the top of the flow limiting box 45, a blocking block 71 is slidably connected to the limiting slide bar 7, and a third spring 72 is sleeved on the limiting slide bar 7, the bottom of the blocking block 71 slides in contact with the top of the flow limiting box 45, and the blocking block 71 is located above the flat pressure hole 457; a guide rod 73 is fixedly connected between the inner walls of the transfer frame 3, the guide rod 73 passes through the side wall of the blocking block 71, a resistance block 731 is fixedly connected to the guide rod 73, and the resistance block 731 is located above the second conveyor belt 2.

[0044] Through the setting of the above-mentioned structure, when the flow limiting box 45 moves to the top of the second conveyor belt 2, the resistance block 731 will first push the blocking block 71 to move along the limiting slide bar 7 to the side of the compressed third spring 72, thereby contacting the blockage of the flat pressure hole 457, so that part of the external airflow enters the adsorption plate 46, thereby releasing the adsorption effect of the adsorption plate 46 and facilitating unloading.

[0045] Reference Figure 1-Figure 8 In the present invention, when in use, when the heat sink is conveyed to the bottom of the transfer rack 3 via the first conveyor belt 1, the first conveyor belt 1 and the second conveyor belt 2 are paused at the same time. At this time, the electric cylinder 44 pushes the flow limiting box 45 to move downward, so that the flow limiting box 45 is sleeved on the heat sink. During the downward movement of the flow limiting box 45, the compression ring 452 is compressed into the air pressure chamber 451, and the compressed gas in the air pressure chamber 451 enters the adsorption plate 46 along the sealing ring 454 and the air guide pipe 456, and then is discharged outward from the bottom of the adsorption plate 46, thereby generating a downward airflow effect on the top of the heat sink, and under the wrapping effect of the flow limiting box 45, a blowing effect can only be generated in a small area where the heat sink is located, thereby achieving a flow collection effect, which effectively makes The dust and impurities attached to the heat sink are blown away, thereby improving the cleanliness of the heat sink; as the electric cylinder 44 continues to extend, the adsorption plate 46 will eventually fit on the top of the heat sink, and at this time, the double-headed motor 47 is turned on to drive the clamping screws 471 on both sides to rotate in opposite directions, so that the clamping plates 472 on both sides approach the heat sink at the same time, and finally the heat sink is clamped and fixed, and the electric cylinder 44 drives the current limiting box 45 to retract, and under the rebound action of the first spring 453, the sealing ring 454 will be reset and moved downward, and at this time, the port of the adsorption plate 46 is fit to the top of the heat sink and blocked, so a suction effect will be generated in the adsorption plate 46, thereby auxiliary fixing the heat sink from the top, effectively improving the stability of the heat sink during transportation.

[0046] When the electric cylinder 44 retracts, the cross plug block 512 will be plugged into the cross plug box 511. At this time, the external gear 513 and the fixed rack 56 are in a meshing state. Then the servo motor 41 drives the transfer screw 4 to rotate, so that the sliding block 42 slides along the transfer screw 4 toward the second conveyor belt 2, thereby driving the heat sink to move toward the second conveyor belt 2. At the same time, the meshing relationship between the external gear 513 and the fixed rack 56 will synchronously drive the two sections of the air guide tube 456 to rotate. During the rotation of the air guide tube 456, the repulsion between the first magnetic plate 52 and the second magnetic plate 53 will cause the second magnetic plate 53 to rotate. The plate 53 slides toward one side of the compressed second spring 54 to squeeze the gas in the compressed air groove 5 and open the one-way valve in the inflation tube 551, so that the air flow is blown toward the heat sink along the inflation tube 551, the air guide ring 55 and the air guide rod 51. At the same time, by utilizing the meshing relationship between the internal gear 514 and the linkage gear 57, when the air guide rod 51 rotates, the adsorption plate 46 is also driven to rotate synchronously, thereby driving the heat sink to rotate as a whole, and the blowing end position of the air guide rod 51 remains unchanged, so that the heat sink can be fully cleaned, which effectively improves the cleaning effect and ensures the quality of subsequent heat sink processing. When the first magnetic plate 52 and the second magnetic plate 53 are separated from the repulsive area, suction will be generated in the compressed air groove 5, so that the airflow passes through the airflow groove 421 and the air inlet pipe 6 to enter the compressed air groove 5 for replenishment, thereby ensuring continuous blowing and cleaning effect. At the same time, in the process of the airflow passing through the airflow groove 421, the heat generated by the threaded rotation between the transfer screw 4 and the sliding block 42 will be taken away, thereby effectively reducing the friction loss between the two and improving the durability of both.

[0047] When the flow limiting box 45 moves to above the second conveyor belt 2, the resistance block 731 will first push the blocking block 71 to move along the limiting slide bar 7 to the side of the compressed third spring 72, thereby contacting the blockage of the equalizing hole 457, so that part of the external airflow enters the adsorption plate 46, thereby releasing the adsorption effect of the adsorption plate 46, and then the electric cylinder 44 extends downward, and then the double-headed motor 47 rotates in the opposite direction, and finally the heat sink will be transferred to the second conveyor belt 2, thereby completing the self-transfer and cleaning operations, effectively improving the processing efficiency.
