Different process equipment can be combined in series according to process requirements. It can also realize automatic loading and unloading of products, and can meet the operational requirements of continuous production of products, thereby improving the work efficiency of heat sink mounting.

[0040] In one embodiment, see Figures 7 to 13 The mounting device 3 includes a mounting workbench 31, a first transport device 32, a mounting fixed platform 33, a mounting lifting mechanism and a mounting head 35. The mounting head 35 is used to install the heat dissipation cover on the product. The mounting heads 35 are all slidably arranged on the mounting workbench 31. The mounting heads 35 have the freedom to move in the horizontal direction relative to the mounting workbench 31. The first transport device 32 is arranged on the mounting workbench 31. The first transport device 32 is used to transport the product and pass through the mounting fixed platform 33 during transportation. The mounting fixed platform 33 is movably arranged on the mounting workbench 31, and the position of the mounting fixed platform 33 matches the position of the mounting head 35. The mounting fixed platform 33 is used to support and fix the product. The mounting lifting mechanism is used to drive the mounting workbench 31 to move in the vertical direction.

[0041] Specifically, the mounting head 35 is a component used to grab or absorb the heat dissipation cover and mount the heat dissipation cover on the product. The mounting head 35 is slidably arranged on the mounting workbench 31. The mounting head 35 has the freedom to move in the horizontal direction relative to the mounting workbench 31.

[0043] In the initial position, the mounting and fixing platform 33 is located below the first transport device 32. When working, the product is placed on the first transport device 32, and then the product is transported to the top of the mounting and fixing platform 33 by the first transport device 32. Then the mounting and lifting mechanism drives the mounting and fixing platform 33 to rise, so that the mounting and fixing platform 33 lifts the product off the first transport device 32 and fixes it on the mounting and fixing platform 33. Finally, the heat sink is grabbed or sucked by the mounting head 35 and mounted on the surface of the product. After the heat sink mounting work is completed, the mounting and lifting mechanism drives the mounting and fixing platform 33 to descend, and the product is placed back on the first transport device 32 and released at the same time, so that the first transport device 32 can transport the product away from the mounting and fixing platform 33, making the mounting of the heat sink more convenient.

[0044] In one embodiment, see Figure 7 , there are multiple mounting heads 35, and there are multiple mounting fixed platforms 33 and mounting top-lifting mechanisms. Each mounting head 35 corresponds to a group of mounting fixed platforms 33 and mounting top-lifting mechanisms.

A precision driving group 355 is also arranged between the moving slider 352 and the transport clamping assembly 353. The precision driving group 355 is used to drive the transport clamping assembly 353 to reciprocate along the first direction.

[0049] Specifically, the main body 351 refers to a component with a certain volume, and the main body 351 can be a block, a plate, or a combination of multiple shapes. The main body 351 can be slidably set on the workbench of the equipment.

Similarly, the sliding structure can be a slide rail slider structure, or a slide rail roller structure, etc. The long-distance drive group 354 refers to a component that can drive an object to move quickly over a long distance, such as a screw drive structure, an electric push rod or a belt drive structure, etc. Its characteristics are that it can drive an object to move quickly and over a long distance, but the movement accuracy is poor. The precision drive group 355 refers to a component that can drive an object to move short distances with high precision, such as a cylinder drive or a hydraulic cylinder drive, etc. The precision drive group 355 is characterized in that it can drive an object to move with high precision, but the movement stroke of the object is usually relatively short.

[0050] The moving slider 352 is slidably connected to the main body 351, and a transport clamping assembly 353 for grabbing the heat dissipation cover and attaching the heat dissipation cover to the surface of the product is also slidably arranged on the moving slider 352. A long-distance driving group 354 is arranged between the moving slider 352 and the main body 351.

The driving end of the precision driving group 355 is connected to the transport clamping assembly 353. The precision driving group 355 is used to drive the transport clamping assembly 353 to reciprocate along the first direction. When the heat dissipation cover is being grabbed, the moving slider 352 and the transport clamping assembly 353 can be first driven by the long-distance driving group 354 to quickly move to a position close to the heat dissipation cover along the first direction, and then the transport clamping assembly 353 can be driven by the precision driving group 355 to move until it contacts the heat dissipation cover. When mounting the heat sink cover, the long-distance drive group 354 can first be used to drive the moving slider 352 and the transport and clamping assembly 353 to quickly move to a position close to the product along the first direction, and then the precision drive group 355 can be used to drive the transport and clamping assembly 353 to move until the heat sink cover is attached to the product, so as to achieve the special mounting operation of the heat sink cover. Compared with the heat sink cover mounting head 35 in the prior art, the long-distance drive group 354 and the precision drive group 355 can be used to drive the transport and clamping assembly 353 to move, and the accuracy of the movement of the transport and clamping assembly 353 can be guaranteed under the premise of ensuring the movement speed and distance of the transport and clamping assembly 353.

[0051] In one embodiment, see Figure 8, the precision drive group 355 includes a pressing cylinder 3551 and a proportional valve 3552. The pressing cylinder 3551 is arranged on the moving slider part 352, and the driving end of the pressing cylinder 3551 is connected to the transport clamping assembly 353. The proportional valve 3552 is connected to the pressing cylinder 3551 pipeline. The proportional valve 3552 is used to adjust the amount of air passing through itself to adjust the thrust output by the pressing cylinder 3551. Specifically, the pressing cylinder 3551 refers to a component that drives the piston to reciprocate through compressed air or other gases to achieve the movement of the object. In order to further improve the movement accuracy of the pressing cylinder 3551, the pressing cylinder 3551 can adopt a low-friction cylinder. The proportional valve 3552 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 3552 in this embodiment can adopt an electromagnetic proportional valve 3552. The pressing cylinder 3551 is used to drive the transport clamping assembly 353 to move in the first direction. The movement state and movement distance of the pressing cylinder 3551 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 clamping assembly 353 is improved. At the same time, the proportional valve 3552 is connected to the pipeline of the pressing cylinder 3551, and the gas flow entering the pressing cylinder 3551 can be adjusted during the working process of the pressing cylinder 3551, so as to achieve the purpose of adjusting the thrust output by the pressing cylinder 3551, 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.

[0052] In an alternative embodiment, see Figure 8 The precision drive group 355 may further include a control valve 3553, which is also connected to the pipeline of the pressing cylinder 3551. The control valve 3553 refers to a component that can control the on-off of the pipeline. In this embodiment, the control valve 3553 may be an electromagnetic control valve 3553. By setting the control valve 3553, the on-off and air intake direction of the high-pressure gas entering the pressing cylinder 3551 can be adjusted, making the state control of the pressing cylinder 3551 more convenient.

[0053] It should be noted that the proportional valve 3552 can be arranged on the main body 351 or the moving slider 352, and the control valve 3553 can also be arranged on the main body 351 or the moving slider 352. In order to make the overall layout of the equipment more reasonable, the proportional valve 3552 and the control valve 3553 can be fixed to the main body 351 by fasteners, so that the installation of the two is more secure.
