[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Please refer to Figures 1 to 4 As shown, in this embodiment of the invention, a heat sink cover mounting head is provided. The heat sink cover mounting head includes a main body 1, a moving slider 2, and a transport and clamping assembly 3. The moving slider 2 is slidably connected to the main body 1, and the transport and clamping assembly 3 is slidably connected to the moving slider 2. The transport and clamping assembly 3 is used to grip the heat sink cover and mount it onto the surface of the product. A long-distance drive group 4 is provided between the moving slider 2 and the main body 1. The long-distance drive group 4 is used to drive the moving slider 2 to reciprocate along a first direction. A precision drive group 5 is also provided on the moving slider 2. The drive end of the precision drive group 5 is connected to the transport and clamping assembly 3. The precision drive group 5 is used to drive the transport and clamping assembly 3 to reciprocate along the first direction.

[0031] Specifically, the main body 1 refers to a component with a certain volume. The main body 1 can be block-shaped, plate-shaped, or a combination of various shapes. The main body 1 can be slidably mounted on the worktable of the equipment. The moving slider 2 also refers to a component with a certain volume. The moving slider 2 can be block-shaped, plate-shaped, or a combination of various shapes. The moving slider 2 can be slidably connected to the main body 1 via a sliding structure, which can be a slide rail slider structure, a slide rail roller structure, etc. The transport clamping assembly 3 refers to a component or assembly that can grip the heat sink cover. The transport clamping assembly 3 can grip the heat sink cover using vacuum adsorption, such as a vacuum suction cup or vacuum head, or it can grip it using clamping, such as a clamping cylinder. The transport clamping assembly 3 can be slidably connected to the moving slider 2 via a sliding structure. Similarly, the sliding structure can be a slide rail slider structure, a slide rail roller structure, etc.

[0032] Long-distance drive group 4 refers to components that can drive objects to move quickly over long distances, such as lead screw drive structures, electric linear actuators, or belt drive structures. Its characteristic is that it can drive objects to move quickly and over long distances, but the accuracy of the movement is relatively poor. Precision drive group 5 refers to components that can drive objects to move short distances with high precision, such as those using pneumatic cylinders or hydraulic cylinders. The characteristic of precision drive group 5 is that it can drive objects to move with high precision, but the stroke of the object's movement is usually relatively short.

[0033] The heat sink cover mounting head provided in this embodiment of the invention comprises a sliding slider 2 slidably connected to a main body 1. A transport and clamping assembly 3 for gripping and attaching the heat sink cover to the surface of the product is also slidably disposed on the sliding slider 2. A long-distance drive group 4 is disposed between the sliding slider 2 and the main body 1, driving the sliding slider 2 to reciprocate along a first direction. A precision drive group 5 is also disposed on the sliding slider 2, with its drive end connected to the transport and clamping assembly 3, driving the transport and clamping assembly 3 to reciprocate along the first direction. During the heat sink cover gripping operation, the long-distance drive group 4 first drives the sliding slider 2 and the transport and clamping assembly 3 to move rapidly along the first direction to a position close to the heat sink cover, and then the precision drive group 5 drives the transport and clamping assembly 3 to move until it contacts the heat sink cover. During the heatsink cover mounting process, the long-distance drive group 4 first drives the sliding slider 2 and the transport clamping assembly 3 to move rapidly along the first direction to a position close to the product. Then, the precision drive group 5 drives the transport clamping assembly 3 to move until the heatsink cover is adhered to the product, thus achieving the special mounting operation of the heatsink cover. Compared with the heatsink cover mounting head in the prior art, the long-distance drive group 4 and the precision drive group 5 work together to drive the transport clamping assembly 3. This ensures both the speed and distance of the transport clamping assembly 3's movement, as well as the accuracy of its movement, making the heatsink cover mounting more convenient.

[0034] In one embodiment, see Figure 1The precision drive assembly 5 includes a pressing cylinder 51 and a proportional valve 52. The pressing cylinder 51 is mounted on the moving slider part 2, and its drive end is connected to the transport and clamping assembly 3. The proportional valve 52 is connected to the pressing cylinder 51 via a pipeline and is used to adjust the amount of air passing through it, thereby adjusting the thrust output by the pressing cylinder 51. Specifically, the pressing cylinder 51 is a component that drives a piston to reciprocate by compressed air or other gas, thereby driving the object to move. To further improve the motion accuracy of the pressing cylinder 51, a low-friction cylinder can be used. The proportional valve 52 is a hydraulic valve that converts the input electrical signal into force or displacement proportionally, thereby continuously controlling parameters such as pressure and flow rate. In this embodiment, the proportional valve 52 can be an electromagnetic proportional valve. A pressing cylinder 51 is used to drive the transport and pressing assembly 3 to move in the first direction. During the driving process, the movement state and distance of the pressing cylinder 51 can be controlled by controlling the on / off state of the high-pressure pipeline, thus improving the movement accuracy of the transport and pressing assembly 3. At the same time, the proportional valve 52 is connected to the pipeline of the pressing cylinder 51, which allows for the adjustment of the gas flow rate into the pressing cylinder 51 during its operation. This achieves the purpose of adjusting the thrust output of the pressing cylinder 51, thereby ensuring that the heat sink cover can be attached to the surface of the product with the most suitable pressure, improving the quality of heat sink mounting.

[0035] In an optional embodiment, please refer to Figure 1 The precision drive assembly 5 may also include a control valve 53, which is also connected to the pipeline of the pressing cylinder 51. The control valve 53 is a component that can control the opening and closing of the pipeline. In this embodiment, the control valve 53 can be an electromagnetic control valve 53. By setting the control valve 53, the opening and closing of the high-pressure gas entering the pressing cylinder 51 and the direction of air intake can be adjusted, making the state control of the pressing cylinder 51 more convenient.

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

[0037] In one embodiment, see Figure 1 and Figure 3The long-distance drive assembly 4 includes a rotating screw 41 and a drive motor 42. The rotating screw 41 is rotatably mounted on the main body 1, and its length direction is along a first direction. The drive motor 42 drives the rotating screw 41 to rotate around its own axis, and the rotating screw 41 is screwed to at least a portion of the moving slider 2. Specifically, the rotating screw 41 refers to a rod-shaped component of a certain length, and a threaded structure is provided on its outer wall. A threaded hole, also along the first direction, can be provided on the moving slider 2. The rotating screw 41 is threadedly connected to the moving slider 2 by passing through the threaded hole. The drive motor 42 is a component that can output rotational torque. The body of the drive motor 42 can be fixed on the main body 1, and the drive end of the drive motor 42 can be connected to the end of the rotating screw 41 via a coupling or the like. When the moving slider 2 moves, the rotating screw 41 can be driven to rotate by the drive motor 42, so that the moving slider 2 slides along the length direction of the rotating screw 41, making the long-distance drive group 4 more convenient to use.

[0038] In an optional embodiment, please refer to Figure 2 The moving slider part 2 has a protrusion 21 on its side, and a threaded hole is provided on the protrusion 21, which extends through the protrusion 21 along a first direction. Specifically, the protrusion 21 refers to a block-shaped component with a certain volume. The protrusion 21 can be an integral structure with the moving slider part 2, or it can be a separate structure connected by fasteners, welding, or snap-fit. The protrusion 21 makes it easier for the rotating screw 41 to pass through the threaded hole.

[0039] In another embodiment, please refer to Figure 1 The long-distance drive assembly 4 may also include an electric push rod, which is a component or assembly that pushes an object to move. In use, the electric push rod can be installed on the main body 1 and the drive end of the electric push rod can be connected to the motion slider 2. The use of an electric push rod as a finished component in the long-distance drive assembly 4 can make the overall structure of the heat sink cover mounting head simpler and easier to assemble.

[0040] In one embodiment, see Figure 1 The number of transport clamping components 3 is multiple, and the number of precision drive groups 5 corresponds to the number of transport clamping components 3. Multiple transport clamping components 3 are arranged sequentially at intervals along a second direction, which is perpendicular to the first direction. Specifically, the transport clamping components 3 are arranged sequentially at intervals along the second direction, and each transport clamping component 3 cooperates with one precision drive group 5. This allows multiple transport clamping components 3 to be installed together during the heat sink mounting process, improving the efficiency of heat sink mounting.

[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 mounted on the moving slider part 2, and the vacuum suction unit 32 is mounted on the suction support 31. The vacuum suction unit 32 is used to connect to an external vacuum generator pipeline to adsorb the heat sink onto the surface of the vacuum suction unit 32. 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 various shapes. The suction support 31 can be slidably mounted on the moving slider part 2 via a sliding structure, which can be a slide rail slider structure, a slide rail roller structure, etc. The vacuum suction unit 32 is a component that can suction objects by generating negative pressure. The vacuum suction unit 32 can be provided with a vacuum cavity and multiple vacuum holes communicating with the vacuum cavity. In use, by connecting the vacuum cavity to an external vacuum generator pipeline, the external vacuum generator can be a vacuum pump, etc. The external vacuum generator can generate negative pressure at the vacuum holes, thereby allowing the vacuum suction unit 32 to suction the heat sink. Meanwhile, the vacuum suction unit 32 is set 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 drive group 5, thereby making it more convenient to suction the heat sink cover.

[0042] In one embodiment, see Figure 4 The vacuum suction unit 32 includes a vacuum mounting base 321 and a vacuum suction head 322. The vacuum mounting base 321 is mounted on the suction support 31. The vacuum suction head 322 is detachably connected to the vacuum mounting base 321. The vacuum mounting base 321 has a connecting channel. The first end of the connecting channel is used to connect to the pipeline of an external vacuum generator. When the vacuum suction head 322 is connected to the vacuum mounting base 321, the vacuum suction head 322 and the second end of the connecting channel are interconnected. Specifically, the vacuum suction head 322 refers to a block-shaped component with a certain volume. The shape of the vacuum suction head 322 can be block-shaped, columnar, or plate-shaped, etc. A vacuum cavity can be set inside the vacuum suction head 322, and multiple vacuum holes communicating with the vacuum cavity are provided on the bottom surface of the vacuum suction head 322. The vacuum mounting base 321 is also a component with a certain volume. The vacuum mounting base 321 can be block-shaped, columnar, or plate-shaped, etc. The vacuum mounting base 321 is provided with a connection channel. The first end of the connection channel is used to connect to the pipeline of an external vacuum generator. When the vacuum nozzle 322 is connected to the vacuum mounting base 321, the vacuum nozzle 322 is interconnected with the second end of the connection channel, thereby realizing the connection between the vacuum nozzle 322 and the external vacuum generator. In addition, the vacuum nozzle 322 can be detached from the vacuum mounting base 321, allowing the vacuum nozzle 322 to be easily removed, so that a matching vacuum nozzle 322 can be replaced according to the size of the heat sink cover.

[0043] In an optional embodiment, please refer to Figure 5 and Figure 6 A disassembly structure is also provided between the vacuum mounting base 321 and the vacuum suction head 322. The disassembly structure may include a magnetic component 323 provided on the vacuum mounting base 321. In this case, the vacuum suction head 322 is made of a material that can attract the magnetic component 323, such as 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. Alternatively, magnetic components can also be provided on the vacuum suction head 322, so that mutual magnetic attraction between the vacuum suction head 322 and the magnetic component 323 can be achieved through two sets 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, please refer to Figure 5 The vacuum mounting base 321 is also provided with a positioning post 324, which is located on the surface of the vacuum mounting base 321 that contacts the vacuum suction head 322. The vacuum suction head 322 is also provided with a positioning hole 325 for cooperating with the positioning post 324. The cooperation between the positioning post 324 and the positioning hole 325 can make the installation position of the vacuum suction head 322 on the vacuum mounting base 321 more accurate, thereby improving the accuracy of heat sink suction.

[0045] In addition, an opening of the connecting channel on the vacuum mounting base 321 can be set at the end of the positioning post 324. At this time, a connecting opening for communicating with the vacuum chamber is also provided at the bottom of the positioning hole 325 on the vacuum suction head 322, so that when the positioning post 324 is inserted into the positioning hole 325, the vacuum chamber is connected to the connecting channel.

[0046] In one embodiment, see Figure 4 The vacuum mounting base 321 is rotatably mounted on the suction support 31, and the suction support 31 is equipped with a rotating unit 33. The driving end of the rotating unit 33 is connected to the vacuum mounting base 321 to drive the vacuum mounting base 321 to rotate around its own axis. Specifically, the rotating unit 33 refers to a component or assembly that can output torque, such as a motor, rotary cylinder, or hydraulic motor. By rotatably mounting the vacuum mounting base 321 on the suction support 31, and simultaneously detaching and mounting the vacuum suction head 322 onto the vacuum mounting base 321, and then connecting the driving end of the rotating unit 33 to the vacuum mounting base 321, the vacuum suction head 322 can be driven to rotate to a suitable angle in the horizontal plane according to the position of the heat sink cover, making the suction of the heat sink cover more convenient.

[0047] In an optional embodiment, please refer to Figure 4A rotary bearing 36 is also provided between the vacuum mounting base 321 and the suction support 31. Specifically, the rotary bearing 36 is a component that reduces the friction between the two rotating parts. A columnar portion may be provided on the vacuum mounting base 321, and the rotary bearing 36 is fitted onto this columnar portion. Simultaneously, a mounting recess for accommodating the rotary bearing 36 is provided on the suction support 31. By providing the rotary bearing 36 between the vacuum mounting base 321 and the suction support 31, the rotation of the vacuum mounting base 321 can be made more convenient and smooth.

[0048] In one embodiment, see Figure 4 A pressure sensor 6 for detecting pressure is installed between the drive end of the precision drive assembly 5 and the transport clamping assembly 3. Specifically, the pressure sensor 6 is a component that uses a microsystem structure to convert external pressure into a usable signal using a certain method. Its working principle is diverse, mainly including piezoelectric effect, piezoresistive effect, strain effect, and capacitance change. By connecting the drive end of the precision drive assembly 5 with the transport clamping assembly 3, the pressure value applied by the transport clamping assembly 3 to the heat sink cover can be detected when the heat sink cover is attached, thus ensuring the quality of the heat sink cover attachment.

[0049] In an optional embodiment, please refer to Figure 4 A drive connecting block 34 is provided on the drive end of the precision drive assembly 5. The drive connecting 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 element 352. The guide rod 351 passes through the drive connecting block 34 and is slidably connected to the drive connecting block 34. The two ends of the guide rod 351 are located on both sides of the drive connecting block 34. One end of the guide rod 351 is connected to the suction support 31. The elastic element 352 is provided between the other end of the guide rod 351 and the drive connecting block 34. A protrusion, such as a nut, can be provided on the other end of the guide rod 351. One end of the elastic element 352 abuts against the protrusion and the other end abuts against the side of the drive connecting block 34. Through the elastic element 352, a force away from the product direction can be applied to the guide rod 351 and the suction support 31. The direction of this force is usually vertically upward to overcome gravity. The elastic element 352 can be a spring, which, when fitted onto the outside of the guide rod 351, makes the installation of the elastic element 352 more stable. The buffer structure 35 can provide a certain degree of buffering during the return stroke of the precision drive assembly 5 through the contraction of the elastic element 352. Thus, under the action of the gravity of the transport clamping assembly 3 itself, the movement of the suction support 31 can be slightly delayed behind the drive end of the precision drive assembly 5, which can, to a certain extent, prevent the transport clamping assembly 3 from moving too fast and causing damage.

[0050] It should be noted that the pressure sensor 6 can be located between the drive connecting block 34 and the suction support 31. The pressure sensor 6 can be located on the drive connecting block 34 or on the suction support 31.

[0051] In one embodiment, see Figure 2 The motion slider 2 is equipped with a distance detection unit 7 and a vision recognition unit 8. The distance detection unit 7 is used to detect the distance between the transport clamping assembly 3 and the product, and the vision recognition unit 8 is used to detect the position of the product. Specifically, the distance detection unit 7 is a device or component that can detect the position or distance of an object. The distance detection unit 7 can be a laser sensor, an ultrasonic sensor, or an infrared sensor, etc. The vision recognition unit 8 is a component that simultaneously recognizes the position or state of an object using an image. The vision recognition unit 8 can be a CCD (Charge-Coupled Device) vision recognition unit 8.
