[0031] Next, the working principle of the test independent station 12 described above will be described: Place the heat dissipation module 20 to be detected at the mounting station 110 of the cantilever beam 100; Start the pressing device 400, and the pressing cylinder 420 drives the pressing plate 410 to press downward, so that the pressing plate 410 presses the heat dissipation module 20 on the mounting station 110 to prevent loosening; As shown in Figure 8As shown, the driving part 550 drives the lifting plate 530 to descend, the lifting plate 530 simultaneously drives the piston cylinder 562 to descend, the glue inlet one-way valve 565 is in a closed state, the glue outlet one-way valve 566 is in an open state, and the heat-conducting glue in the pump cavity 30 is pumped out from the glue outlet conduit 564 and sent to the heating end 540; As shown, the driving part 550 drives the lifting plate 530 to ascend, the lifting plate 530 simultaneously drives the piston cylinder 562 to ascend, the glue inlet one-way valve 565 is in an open state, the glue outlet one-way valve 566 is in a closed state, and the heat-conducting glue in the glue storage tank 561 is pumped into the pump cavity 30 for use; Figure 9 As shown, the driving part 550 drives the lifting plate 530 to ascend, the lifting plate 530 simultaneously drives the piston cylinder 562 to ascend, the glue inlet one-way valve 565 is in an open state, the glue outlet one-way valve 566 is in a closed state, and the heat-conducting glue in the glue storage tank 561 is pumped into the pump cavity 30 for use; The driving part 550 continues to drive the lifting plate 530 to ascend, the lifting plate 530 drives the heating end 540 thereon to ascend and contact the bottom of the heat dissipation module 20 (a slot hole is formed in the cantilever beam 200 to pass through the bottom of the heat dissipation module 20, and the elastic member 570 provides a buffer elastic force), the heating end 540 conducts heat to the heat dissipation module 20, thereby simulating a heat dissipation scene in which the heat dissipation module 20 is installed on an electronic device (such as a graphics card or a mainboard); at the same time, after the heating end 540 contacts the bottom of the heat dissipation module 20, the vibrator 580 vibrates the heating end 540, so that the heat-conducting glue on the heating end 540 is evenly spread, and heat conduction is more uniform; The air blowing device 300 is used for air cooling and heat dissipation of the heat dissipation module 20, and the heat dissipation performance of the heat dissipation module 20 under different wind speed states is tested; At the same time, the cantilever beam 200 can be rotated by the handle 120 to adjust the angle, and the heat dissipation module 20 on the cantilever beam 200 also rotates, thereby testing the heat dissipation performance of the heat dissipation module 20 under various different spatial angles; After the test is completed, the driving part 550 drives the lifting plate 530 to descend for the first time and stop, the lifting plate 530 drives the heating end 540 thereon to descend and separate from the heat dissipation module 20, and then the glue scraping cylinder 620 drives the glue scraping shovel 610 to reciprocate to scrape off the old heat-conducting glue on the heating end which has been used; at the time of the first descent, the lifting plate 530 also drives the piston cylinder 562 to descend, and a part of the heat-conducting glue in the pump cavity 30 is pumped out from the glue outlet conduit 564 and sent to the heating end 540, which is fused with the old heat-conducting glue and scraped off together by the glue scraping shovel 610; The driving part 550 drives the lifting plate 530 to descend for the second time and stop, the lifting plate 530 drives the piston cylinder 562 to continue to descend, and the remaining heat-conducting glue in the pump cavity is pumped out from the glue outlet conduit 564 and sent to the heating end 540; At the same time, the pressing cylinder 420 drives the pressing plate 410 to reset, so that the pressing plate 410 separates from the heat dissipation module 20 on the installation work station 110, and the heat dissipation module 20 after the test is completed is taken out from the installation work station 110; The new heat dissipation module 20 to be detected is placed on the mounting station 110 again, and the above-mentioned actions are repeated.

[0032] In the present application, the heating end 540 is arranged on the lifting plate 530 through the elastic member 570, and such a structural design has the following beneficial effects: (1) In the process of the heating end 540 rising and contacting the heat dissipation module 20, the elastic member 570 provides a good buffering elastic force, preventing the heating end 540 from directly impacting the heat dissipation module 20 and damaging it; (2) The vibrator 580 is arranged on the heating end 540, and when the vibrator 580 vibrates, the heating end 540 is flexibly pressed on the bottom of the heat dissipation module 20 under the cooperation of the elastic member 570, so that the whole heating end 540 can vibrate well, so that the heat-conducting glue on the heating end 540 can be evenly spread to form a thin layer; (3) When the glue scraping cylinder 620 drives the glue scraping shovel 610 to reciprocate to scrape off the used old heat-conducting glue on the heating end, the glue scraping shovel 610 will be pressed on the heating end, and the heating end will be adaptively avoided under the buffering elastic force of the elastic member 570, so that the glue scraping shovel 610 can better contact the heating end, and the heat-conducting glue can be completely scraped off.

[0033] In the present application, the glue storage tank 561 for storing the heat-conducting glue is arranged on the fixed plate 520 away from the heating end 540, and the glue storage tank 561 is away from the heat source, preventing the heat-conducting glue in the glue storage tank 561 from being affected by the heat source for a long time and deteriorating.

[0034] Further, the glue applying system 560 of the present application fully utilizes the lifting movement of the lifting plate 530, so that the heat-conducting glue in the glue storage tank 561 is pumped out to the heating end 540 in a limited amount, greatly improving the automation level. When the driving part 550 drives the lifting plate 530 to descend, the lifting plate 530 simultaneously drives the piston cylinder 562 to descend, so that the heat-conducting glue in the pump cavity 30 is pumped out from the glue outlet conduit 564 and delivered to the heating end 540; when the driving part 550 drives the lifting plate 530 to ascend, the lifting plate 530 simultaneously drives the piston cylinder 562 to ascend, so that the heat-conducting glue in the glue storage tank 561 is pumped into the pump cavity 30 for use.

[0035] The above-mentioned embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as limiting the scope of the patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
