Description

Technical Field

[0001] The invention relates to the technical field of vapor chamber power testing devices, and in particular to an automated power testing device for an ultra-thin vapor chamber. Background Art

[0002] An ultra-thin vapor chamber is a heat transfer element with ultra-high thermal conductivity, usually composed of a shell, support columns, a vacuum cavity, a liquid wick and a working fluid. It is based on the gas-liquid phase change of the internal working fluid and achieves efficient heat exchange through the huge latent heat of phase change. During the production process, it is necessary to conduct a power heat dissipation test to detect the quality of the ultra-thin vapor chamber.

[0003] The Chinese patent application No. 201610973656.0 discloses a device for detecting thermal resistance and heat dissipation power of an ultra-thin heat spreader. During the test, the ultra-thin heat spreader is placed on a workbench, a water-cooled plate is placed on top of the ultra-thin heat spreader, and a pressure device is pressed downward to make the water-cooled plate fit the ultra-thin heat spreader. Cooling water flows through the water-cooled plate, and the temperature change of the cooling water is detected by a thermometer to calculate the heat dissipation power of the ultra-thin heat spreader. However, during the above test, personnel are required to place the ultra-thin heat spreaders one by one on the workbench for testing. In this way, when the personnel's hands take the ultra-thin heat spreader, it is easy to accidentally touch the test device or other objects, resulting in bumps and scratches on the surface of the ultra-thin heat spreader, affecting the quality of the ultra-thin heat spreader. In addition, the ultra-thin heat spreader needs to be taken by hand during the test, which not only increases the workload of the staff, but also reduces the test efficiency of the ultra-thin heat spreader.

[0035] Example 2

[0036] Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The lifting assembly includes two groups of L-shaped frames 206 installed on the back of the placement plate 103. A top frame 207 is fixedly installed on the top of the L-shaped frame 206. A hydraulic cylinder 208 is fixedly installed on the top frame 207.

[0037] The present invention uses a designed conveying mechanism to place multiple groups of stacked ultra-thin heat spreader bodies 104 on the rubber plate 210 on the top of the left plate 212 during use, and then use multiple groups of suction cups 217 to suck the ultra-thin heat spreader bodies 104 and move them to the top of the heat source 101, and then the suction cups 217 release the ultra-thin heat spreader bodies 104 and move them to the outside of the heat source 101, and then the water-cooled plate 102 moves downward to press the ultra-thin heat spreader bodies 104 to start testing. When the test is completed, the ultra-thin heat spreader bodies 104 are sucked by the suction cups 217 and moved to the right side of the device, and the ultra-thin heat spreader bodies 104 are placed on the rubber plate 210 on the top of the right plate 211 to complete the test, thereby realizing automatic conveyance of the ultra-thin heat spreader bodies 104 during testing, improving the efficiency of the test device in testing the heat dissipation power of the ultra-thin heat spreader bodies 104, and reducing the labor generated for personnel.

[0038] During use, the stacked ultra-thin heat spreader bodies 104 are placed on the rubber sheet 210 located on the top of the left plate 212, and then the lifting hydraulic rod 213 is turned on to raise the left plate 212 to a certain height position, and then the driving motor 214 drives the rotating screw 215 to rotate, and the nut block 216 moves to drive the moving plate 201 to move to a position directly above the stacked ultra-thin heat spreader bodies 104, and then the lifting hydraulic rod 226 drives the moving plate 201 to descend, driving the suction cup 217 to descend, and finally the suction cup 217 contacts the upper surface of the ultra-thin heat spreader body 104, and then the negative pressure pump 219 is turned on to enable the suction cup 217 to generate negative pressure to suck the ultra-thin heat spreader body 104, and then the lifting hydraulic rod 226 works. The upper end of the heat sink 200 is lifted and driven by the moving plate 201 and the suction cup 217 to the appropriate position, and then the motor 214 is driven to drive the rotating screw 215 to continue to rotate, driving the sucked ultra-thin heat sink body 104 to move to the right to be located directly above the heat source 101. At this time, the sucked ultra-thin heat sink body 104 is lowered by the lifting hydraulic rod 226, and finally the bottom contacts the upper surface of the heat source 101, and then the negative pressure pump 219 is turned off. At this time, the suction cup 217 no longer sucks the ultra-thin heat sink body 104, and then the moving plate 201, the suction cup 217, etc. are moved to the outside of the heat source 101, and then the water-cooled plate 102 is lowered and contacts and presses the ultra-thin heat sink body 104 under the action of the hydraulic cylinder 208, and then the ultra-thin heat sink body 104 is tested;

At this time, the movable plate 201 and the suction cup 217 descend and place the tested ultra-thin heat spreader body 104 on the rubber plate 210 located on the top of the right plate 211, and then the motor 214 is driven to reverse so that the movable plate 201, the suction cup 217, etc. return to the left side to automatically transport the remaining ultra-thin heat spreader bodies 104 again.

The first pipeline 300 is fixed on the second blower 306 .

[0043] The cleaning piece designed in the present invention can, before the suction cup 217 sucks the ultra-thin heat spreader body 104, blow air to the upper surface of the ultra-thin heat spreader body 104 located on the top of the left plate 212 through the second blowing head 304 on the square tube 303, so as to blow away foreign matter or dust attached to the upper surface of the ultra-thin heat spreader body 104; after the suction cup 217 sucks the ultra-thin heat spreader body 104 and moves to above the heat source 101, it blows air to the lower surface of the sucked ultra-thin heat spreader body 104 through the first blowing head 301 on the first pipeline 300, so as to blow away foreign matter or dust attached to the lower surface of the ultra-thin heat spreader body 104, thereby reducing the influence of foreign matter or dust on the heat dissipation power test in the subsequent test process and improving the accuracy of the test results.

[0044] During use, before the suction cup 217 sucks the ultra-thin heat spreader body 104, the first blower 305 is turned on, and then the second blowing head 304 on the square tube 303 blows air downward to the ultra-thin heat spreader body 104 located above the left plate 212, so as to blow away foreign matter or dust on the upper surface of the ultra-thin heat spreader body 104. Then, after the suction cup 217 sucks the ultra-thin heat spreader body 104 and moves it to a position directly above the heat source 101, the second blower 306 is turned on, and then the first blowing head 301 is blown outward through the second blower 306 to blow away foreign matter or dust attached to the lower surface of the ultra-thin heat spreader body 104 sucked by the suction cup 217, so as to reduce the influence of foreign matter or dust on the heat dissipation power test during subsequent tests.

The end of the screw rod 402 passes through the inside of the through hole, and the outside of the screw 402 is connected with a spiral ring by a thread.

[0047] The cleaning piece designed in the present invention can clean dust or debris attached to the outer surface of the rotating screw 215 during use, reducing the probability of dust or debris causing wear on the inner wall of the nut block 216 or the outer wall of the rotating screw 215 when the nut block 216 slides on the rotating screw 215, thereby increasing the service life of the nut block 216 or the rotating screw 215.

[0048] During use, when the nut block 216 moves on the rotating screw 215, it will drive the two sets of cleaning brushes 400 to move along. At this time, the cleaning brushes 400 can clean some dust or debris on the outer surface of the rotating screw 215, reducing the amount of attached dust or debris, thereby reducing the chance of dust or debris wearing the inner wall of the nut block 216 or the outer wall of the rotating screw 215 when the nut block 216 slides on the rotating screw 215.
