Compared with the heat sink cover mounting head in the prior art, the purpose of driving the transport and clamping assembly 3 to move can be achieved by the mutual cooperation of the long-distance drive group 4 and the precision drive group 5. Under the premise of ensuring the movement speed and distance of the transport and clamping assembly 3, the accuracy of the movement of the transport and clamping assembly 3 can also be ensured, making the mounting of the heat sink cover more convenient.

[0034] In one embodiment, see Figure 1, the precision drive group 5 includes a pressing cylinder 51 and a proportional valve 52. The pressing cylinder 51 is arranged on the moving slider part 2, and the driving end of the pressing cylinder 51 is connected to the transport clamping assembly 3. The proportional valve 52 is connected to the pressing cylinder 51 pipeline. The proportional valve 52 is used to adjust the amount of air passing through itself to adjust the thrust output by the pressing cylinder 51. Specifically, the pressing cylinder 51 refers to a component that drives the piston to reciprocate through compressed air or other gases, thereby driving the object to move. In order to further improve the movement accuracy of the pressing cylinder 51, the pressing cylinder 51 can adopt a low-friction cylinder. The proportional valve 52 refers to a hydraulic valve that converts the input electrical signal into force or displacement in proportion, thereby continuously controlling parameters such as pressure and flow. Among them, the proportional valve 52 in this embodiment can adopt an electromagnetic proportional valve 52.

The movement state and movement distance of the pressing cylinder 51 can be controlled by controlling the on and off of the high-pressure pipeline during the driving process, so that the movement accuracy of the transport and clamping assembly 3 is improved. At the same time, the proportional valve 52 is connected to the pipeline of the pressing cylinder 51, and the gas flow entering the pressing cylinder 51 can be adjusted during the working process of the pressing cylinder 51, so as to achieve the purpose of adjusting the thrust output by the pressing cylinder 51, thereby ensuring that the heat dissipation cover can be attached to the surface of the product with the most appropriate pressure, thereby improving the quality of heat sink attachment.

[0036] It should be noted that the proportional valve 52 can be arranged on the main body 1 or the moving slider 2, and the control valve 53 can also be arranged on the main body 1 or the moving slider 2. In order to make the overall layout of the equipment more reasonable, the proportional valve 52 and the control valve 53 can be fixed to the main body 1 by fasteners, so that the installation of the two is more secure.

[0037] In one embodiment, see Figure 1 and Figure 3, the long-distance drive group 4 includes a rotating screw 41 and a driving motor 42. The rotating screw 41 is rotatably arranged on the main body 1, and the length direction of the rotating screw 41 is arranged along the first direction.

The driving motor 42 refers to a component that can output a rotational torque. The body of the driving motor 42 can be fixed on the main body 1, and the driving end of the driving motor 42 can be connected to the end of the rotating screw 41 through a coupling or the like. When the moving slider part 2 moves, the rotating screw 41 can be driven to rotate by the driving motor 42, so that the moving slider part 2 slides along the length direction of the rotating screw 41, making the use of the long-distance driving group 4 more convenient.

[0040] In one embodiment, see Figure 1 , there are multiple transport and clamping components 3, the number of precision drive groups 5 corresponds to the number of transport and clamping components 3, and multiple transport and clamping components 3 are arranged in sequence along the second direction, and the second direction is perpendicular to the first direction. Specifically, the transport and clamping components 3 are arranged in sequence along the second direction, and each transport and clamping component 3 cooperates with a precision drive group 5. When mounting the heat sink, multiple transport and clamping components 3 can be mounted together, thereby improving the working efficiency of the heat sink mounting work.

[0041] In one embodiment, see Figure 4 The transport and clamping assembly 3 includes a suction support 31 and a vacuum suction unit 32. The suction support 31 is slidably arranged on the moving slider part 2. The vacuum suction unit 32 is arranged on the suction support 31.

Specifically, the suction support 31 refers to a component with a certain volume. The suction support 31 can be block-shaped, plate-shaped or a combination of multiple shapes. The suction support 31 can be slidably arranged on the moving slider part 2 through a sliding structure, wherein the sliding structure can be a slide rail slider structure, or a slide rail roller structure. The vacuum suction unit 32 refers to a component that can absorb an object by generating negative pressure. The vacuum suction unit 32 can be provided with a vacuum cavity and a plurality of vacuum holes connected to the vacuum cavity. When in use, the vacuum cavity is connected to the pipeline of the external vacuum generating device. The external vacuum generating device can be a vacuum pump, etc. Negative pressure can be generated at the vacuum hole by the external vacuum generating device, so that the vacuum suction unit 32 can absorb the heat sink cover. At the same time, the vacuum suction unit 32 is arranged on the suction support 31, so that the suction support 31 can move together with the suction support 31 under the action of the precision driving group 5, so that the suction of the heat dissipation cover is more convenient.

[0042] In one embodiment, see Figure 4 The vacuum suction unit 32 includes a vacuum mounting seat 321 and a vacuum suction head 322. The vacuum mounting seat 321 is arranged on the suction support 31. The vacuum suction head 322 is detachably connected to the vacuum mounting seat 321.

Specifically, the vacuum suction head 322 refers to a block component with a certain volume. The shape of the vacuum suction head 322 can be a block, a column, or a plate. The vacuum cavity can be arranged inside the vacuum suction head 322, and a plurality of vacuum holes connected to the vacuum cavity are arranged on the bottom surface of the vacuum suction head 322. The vacuum mounting seat 321 is also a component with a certain volume. The vacuum mounting seat 321 can be a block, a column, or a plate. A connecting channel is provided on the vacuum mounting seat 321, and a first end of the connecting channel is used to connect to a pipeline of an external vacuum generating device, and when the vacuum suction head 322 is connected to the vacuum mounting seat 321, the vacuum suction head 322 and the second end of the connecting channel are communicated with each other, thereby realizing the connection between the vacuum suction head 322 and the external vacuum generating device. In addition, the vacuum suction head 322 is detachably connected to the vacuum mounting seat 321, so that the vacuum suction head 322 can be easily removed, so that a matching vacuum suction head 322 can be replaced according to the size of the heat dissipation cover.

[0043] In an alternative embodiment, see Figure 5 and Figure 6 A disassembly structure is also provided between the vacuum mounting seat 321 and the vacuum suction head 322. The disassembly structure may include a magnetic component 323 provided on the vacuum mounting seat 321. In this case, the vacuum suction head 322 is made of a material that can attract the magnetic component 323, such as metal iron, nickel, or an alloy containing iron or nickel, so as to achieve mutual magnetic attraction between the vacuum suction head 322 and the magnetic component 323. In addition, a magnetic component may also be provided on the vacuum suction head 322, so that the mutual magnetic attraction between the vacuum suction head 322 and the magnetic component 323 is achieved through two groups of magnetic components. The provision of the magnetic component 323 makes the disassembly and connection of the vacuum suction head 322 more convenient.

[0044] In another alternative embodiment, see Figure 5 A positioning column 324 is also provided on the vacuum mounting seat 321. The positioning column 324 is arranged on the surface of the vacuum mounting seat 321 that contacts the vacuum suction head 322. A positioning hole 325 for cooperating with the positioning column 324 is also provided on the vacuum suction head 322. Through the cooperation between the positioning column 324 and the positioning hole 325, the installation position of the vacuum suction head 322 on the vacuum mounting seat 321 can be more accurate, thereby improving the accuracy of the heat sink cover suction.

[0045] In addition, an opening of the connecting channel on the vacuum mounting seat 321 can be set at the end of the positioning column 324. At this time, a connecting opening for communicating with the vacuum cavity is also set at the bottom of the positioning hole 325 on the vacuum suction head 322, so that when the positioning column 324 is inserted into the positioning hole 325, the connection between the vacuum cavity and the connecting channel is realized.

[0046] In one embodiment, see Figure 4 , the vacuum mounting seat 321 is rotatably mounted on the suction support 31, and a rotating unit 33 is disposed on the suction support 31, and the driving end of the rotating unit 33 is connected to the vacuum mounting seat 321 to drive the vacuum mounting seat 321 to rotate around its own axis. Specifically, the rotating unit 33 refers to a component or assembly that can output torque, and the rotating unit 33 can be a motor, a rotary cylinder or a hydraulic motor, etc. By rotatably mounting the vacuum mounting seat 321 on the suction support 31, and disassembling and mounting the vacuum suction head 322 on the vacuum mounting seat 321, and then connecting the driving end of the rotating unit 33 to the vacuum mounting seat 321, the vacuum suction head 322 can be driven by the rotating unit 33 to rotate to a suitable angle in the horizontal plane according to the position of the heat dissipation cover, so that the suction of the heat dissipation cover can be more convenient.

[0047] In an alternative embodiment, see Figure 4A rotating bearing 36 is also provided between the vacuum mounting seat 321 and the suction support 31. Specifically, the rotating bearing 36 refers to a component that reduces the friction between the two rotating parts. A columnar portion may be provided on the vacuum mounting seat 321, and the rotating bearing 36 is sleeved on the columnar portion. At the same time, a mounting nest for accommodating the rotating bearing 36 is provided on the suction support 31. By providing the rotating bearing 36 between the vacuum mounting seat 321 and the suction support 31, the rotation of the vacuum mounting seat 321 can be made more convenient and smooth.

[0048] In one embodiment, see Figure 4 A pressure sensor 6 for detecting pressure is provided between the driving end of the precision driving group 5 and the transport clamping assembly 3. Specifically, the pressure sensor 6 refers to a component that uses a micro-system structure to convert external pressure into a usable signal in a certain way. Its working principles are varied, mainly including piezoelectric effect, piezoresistive effect, strain effect, electrostatic capacitance change, etc. By connecting the driving end of the precision driving group 5 and the transport clamping assembly 3, the pressure value applied by the transport clamping assembly 3 on the heat sink cover can be detected when the transport clamping assembly 3 is mounted on the heat sink cover, thereby ensuring the quality of the heat sink cover mounting.

[0049] In an alternative embodiment, see Figure 4 A driving connection block 34 is provided on the driving end of the precision driving group 5. The driving connection block 34 is movably connected to the suction support 31 through a buffer structure 35. The buffer structure 35 includes a guide rod 351 and an elastic member 352. The guide rod 351 penetrates the driving connection block 34 and is slidably connected to the driving connection block 34. The two ends of the guide rod 351 are respectively located on both sides of the driving connection block 34. One end of the guide rod 351 is connected to the suction support 31. The elastic member 352 is provided between the other end of the guide rod 351 and the driving connection block 34. A protrusion may be provided at the other end of the guide rod 351. The protrusion may be a nut, etc. One end of the elastic member 352 abuts against the protrusion and the other end abuts against the side of the driving connection block 34. The elastic member 352 may apply a force away from the product direction to the guide rod 351 and the suction support 31. The direction of this force is usually vertically upward to overcome gravity. The elastic member 352 may be a spring, which is sleeved on the outside of the guide rod 351 to make the installation of the elastic member 352 more stable. The setting of the buffer structure 35 can provide a certain degree of buffering during the return of the precision drive group 5 through the contraction of the elastic member 352, so that under the action of the gravity of the transport clamping assembly 3 itself, the movement of the suction support 31 can slightly lag behind the driving end of the precision drive group 5, which can avoid damage to the transport clamping assembly 3 due to excessive movement speed to a certain extent.

[0050] It should be noted that the pressure sensor 6 can be arranged at a position between the driving connection block 34 and the suction support 31 , and the pressure sensor 6 can be arranged on the driving connection block 34 or on the suction support 31 .
