Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1-6 shown, an embodiment of an automatic wire drawing device for the flat surface of a heat sink is provided in this embodiment.

[0026] An automatic wire drawing device for the flat surface of a heat sink includes a device main body 1 and a support frame 2. A rotary pressing structure 3 is arranged on the device main body 1. The rotary pressing structure 3 includes a driving motor 4 fixedly installed at the bottom of the device main body 1. A first gear 5 is fixedly installed at the output end of the driving motor 4. A rotating shaft 6 is movably installed on the device main body 1. One end of the rotating shaft 6 is fixedly installed with a base 7, and the other end of the rotating shaft 6 is fixedly installed with a second gear 8 meshing with the first gear 5. A plurality of flexible placement blocks 9 are installed on the top of the base 7. An electric telescopic rod 10 is fixedly installed at the bottom of the support frame 2. A sanding disc 11 is fixedly installed at the output end of the electric telescopic rod 10. Through the setting of the rotary pressing structure 3, the traditional manual method of using a sand belt for wire drawing is changed. This structure uses machinery to perform wire drawing on the heat sink, avoiding the damage caused by the long-term contact between the residue falling off during wire drawing and the worker's skin. After placing a plurality of heat sinks on the flexible placement blocks 9, start the electric telescopic rod 10 to drive the sanding disc 11 to descend until it fits with the heat sink, and then start the driving motor 4 to drive the first gear 5 to rotate. While the first gear 5 rotates, the second gear 8 also rotates accordingly. At this time, the rotating shaft 6 on the second gear 8 drives the base 7 to rotate. When the base 7 rotates, the heat sink can rub against the bottom of the sanding disc 11. By setting the number of rotation circles according to the actual situation, the wire drawing of the heat sink can be completed. This method not only realizes rapid processing, improves production efficiency and product quality, but also protects the labor safety of employees.

[0027] As Figure 5 shown, a plurality of clamping plates 12 are installed on the flexible placement blocks 9. A fixing plate 13 is installed on one side of the flexible placement blocks 9. A bidirectional lead screw 14 is movably installed on the plurality of clamping plates 12. Through the setting of the clamping plates 12, the fixing plate 13 and the bidirectional lead screw 14, rotating the bidirectional lead screw 14 can adjust the distance between the two clamping plates 12, making the interval expand or shrink, so as to clamp heat sinks of different sizes, and the applicable range is wider.

[0028] As Figure 5As shown in the figure, a plurality of grip rods 15 are fixedly installed at one end of the bidirectional lead screw 14. Through the arrangement of the grip rods 15, the force-bearing area at one end of the bidirectional lead screw 14 can be increased, so that the hand is not easily slipped when the personnel rotate the bidirectional lead screw 14, thus facilitating the adjustment of the clamping plate 12.

[0029] As Figure 5 shown in the figure, a chute 16 is formed on the flexible placement block 9, and a slider 17 connected to the clamping plate 12 is movably installed inside the chute 16. Through the arrangement of the chute 16 and the slider 17, the friction between the clamping plate 12 and the flexible placement block 9 can be reduced, making it more labor-saving for the clamping plate 12 to slide on the flexible placement block 9, thus facilitating the adjustment of the distance between the clamping plates 12.

[0030] As Figure 5 shown in the figure, a connecting rod 18 is fixedly installed at the bottom of the flexible placement block 9. A plurality of mounting holes 19 are formed in the connecting rod 18, and a spring 20 is fixedly installed inside the mounting holes 19. One end of the spring 20 is fixedly installed with a clamping block 21. A plurality of grooves 22 adapted to the connecting rod 18 are formed on the base 7, and a plurality of clamping holes 23 cooperating with the clamping block 21 are formed inside the grooves 22. Through the arrangement of the connecting rod 18, the mounting holes 19, the spring 20, the clamping block 21, the grooves 22 and the clamping holes 23, after the connecting rod 18 is inserted into the inside of the groove 22, the clamping block 21 is engaged with the clamping hole 23 under the elastic action of the spring 20, thereby fixing the connecting rod 18 inside the clamping hole 23. Pull the flexible placement block 9 so that the clamping block 21 is squeezed by the inner wall of the groove 22 and shrinks into the inside of the mounting hole 19. After the clamping block 21 disengages from the clamping hole 23, the connecting rod 18 can be pulled out of the groove 22, thus facilitating the disassembly and replacement of the clamping plate 12 when it is damaged.

[0031] As Figure 5 shown in the figure, one end of the clamping block 21 is set to be arc-shaped. Through the setting that one end of the clamping block 21 is arc-shaped, the friction on the surface of one end of the clamping block 21 can be reduced, making it easier for the clamping block 21 to slide on the inner wall of the groove 22, thus facilitating the disassembly and installation of the connecting rod 18.

[0032] As Figure 6 shown in the figure, a maintenance door 24 is arranged on one side of the device main body 1. A first magnetic block 25 is fixedly installed at one end of the maintenance door 24, and a second magnetic block 26 magnetically connected to the first magnetic block 25 is fixedly installed on the device main body 1. Through the arrangement of the maintenance door 24, the first magnetic block 25 and the second magnetic block 26, the internal structure of the device main body 1 can be maintained by opening the maintenance door 24. When the maintenance door 24 is in the closed state, the first magnetic block 25 and the second magnetic block 26 are attracted to each other to fix the maintenance door 24 and prevent the maintenance door 24 from loosening and opening.

[0033] In this embodiment, as Figures 1-6As shown in the figure, the working process of an automatic flat wire drawing device for heat sinks provided in this embodiment is as follows:

[0034] After placing multiple heat sinks on the flexible placement block 9, start the electric telescopic rod 10 to drive the sanding disc 11 to descend until it fits with the heat sink. Then start the drive motor 4 to drive the first gear 5 to rotate. While the first gear 5 rotates, the second gear 8 also rotates accordingly. At this time, the rotating shaft 6 on the second gear 8 drives the base 7 to rotate. When the base 7 rotates, the heat sink can rub against the bottom of the sanding disc 11. By setting the number of rotation circles according to the actual situation, the wire drawing of the heat sink can be completed. This method not only realizes rapid processing, improves production efficiency and product quality, but also protects the labor safety of employees.

[0035] In summary, in this embodiment, according to an automatic flat wire drawing device for heat sinks in this embodiment, through the settings of the clamping plate 12, the fixing plate 13 and the bidirectional lead screw 14, rotating the bidirectional lead screw 14 can adjust the distance between the two clamping plates 12, making the interval expand or shrink, so as to clamp heat sinks of different sizes, with a wider application range. Through the setting of the grip rod 15, the force-bearing area at one end of the bidirectional lead screw 14 can be increased, making it difficult for the hand to slip when the operator rotates the bidirectional lead screw 14, thus facilitating the adjustment of the clamping plate 12. Through the settings of the sliding groove 16 and the sliding block 17, the friction between the clamping plate 12 and the flexible placement block 9 can be reduced, making it more labor-saving for the clamping plate 12 to slide on the flexible placement block 9, thus facilitating the adjustment of the distance between the clamping plates 12. Through the settings of the connecting rod 18, the mounting hole 19, the spring 20, the clamping block 21, the groove 22 and the clamping hole 23, after inserting the connecting rod 18 into the inside of the groove 22, the clamping block 21 is engaged with the clamping hole 23 under the elastic action of the spring 20, thereby fixing the connecting rod 18 inside the clamping hole 23. Pull the flexible placement block 9 so that the clamping block 21 is squeezed by the inner wall of the groove 22 and contracts into the inside of the mounting hole 19. After the clamping block 21 disengages from the clamping hole 23, the connecting rod 18 can be pulled out of the groove 22, thus facilitating the disassembly and replacement of the clamping plate 12 when it is damaged. Through the setting that one end of the clamping block 21 is arc-shaped, the friction on the surface of one end of the clamping block 21 can be reduced, making it easier for the clamping block 21 to slide on the inner wall of the groove 22, thus facilitating the disassembly and installation of the connecting rod 18. Through the settings of the access door 24, the first magnetic block 25 and the second magnetic block 26, opening the access door 24 can perform maintenance on the internal structure of the device main body 1. When the access door 24 is in the closed state, the first magnetic block 25 and the second magnetic block 26 attract each other to fix the access door 24 and prevent the access door 24 from loosening and opening.
