The third driving structure 630 is arranged as a linear cylinder, and drives the up-down moving frame to move in the up-down direction.

[0093] The second driving structure 620 is arranged as a linear cylinder, and is fixedly installed on the up-down moving frame. The output end of the second driving structure 620 is fixedly connected with a first carrying connecting frame, and the second driving structure 620 drives the first carrying connecting frame to move in the front-rear direction.

[0094] The fourth driving structure 640 is installed on the second carrying connecting frame, and the second carrying connecting frame is hingedly connected with a swing connecting frame. The fourth driving structure 640 is arranged as a linear driving device and a connecting rod structure, and drives the swing connecting frame to move around an axis parallel to the left-right direction. The plurality of carrying clamp jaws 650 of the first carrying device 601 are all installed on the swing connecting frame.

[0095] In the second carrying device 602, the second driving structure 620 is fixedly installed on a moving support, the moving support is slidingly connected with a first carrying connecting frame, and the plurality of carrying clamping jaws 650 of the second carrying device 602 are all installed on the first carrying connecting frame.

[0096] The action process of the heat pipe detection equipment is as follows:

[0097] The staff adds the heat pipe into the storage box body 211, adjusts the position of the inner adjusting side wall 212 according to the length of the heat pipe, and adapts to heat pipes of different lengths. Then the heat pipe detection equipment starts to work, the discharging driving member 232 drives the discharging member 231 to move upward, thereby pushing the heat pipe to move upward. When the heat pipe moves to the upper side of the side wall of the storage box body 211 close to the clamping position, the heat pipe will move away from the storage box body 211 and downward due to the guiding effect of the discharging surface 2311, and finally leave the storage box body 211 and enter the discharging device 220 from the gap between the blocking member 242 and the upper end surface of the side wall of the storage box body 211 close to the clamping position.

[0098] After the heat pipe enters the discharging device 220, the heat pipe will enter the first groove body 2211 of the fixed discharging structure 221. Then the front feeding driving structure 223 drives the front feeding discharging structure 222 to move in the upward and downward direction and the left and right direction. In the process of rising, the heat pipe enters the second groove body 2221 and is lifted by the front feeding discharging structure 222. In the process of moving in the left and right direction, the front feeding discharging structure 222 drives the heat pipe to move in the left and right direction with the front feeding discharging structure 222. In the process of descending, the heat pipe reenters the first groove body 2211 of the fixed discharging structure 221. By arranging the front feeding discharging structure 222, the heat pipe can be transported forward at equal intervals, so as to realize discharging of multiple heat pipes.

[0099] The discharging device 230 and the discharging device 220 repeat the above action until eight heat pipes are placed in the fixed discharging structure 221.

[0100] Then the third driving structure 630 of the first carrying device 601 drives the fourth driving structure 640 and the plurality of carrying clamping jaws 650 of the first carrying device 601 to move downward. After the plurality of carrying clamping jaws 650 move downward to the position where the heat pipes are located, the plurality of carrying clamping jaws 650 clamp the plurality of heat pipes respectively. After the carrying clamping jaws 650 clamp the heat pipes, the third driving structure 630 drives the plurality of carrying clamping jaws 650 to move upward, so that the heat pipes move away from the discharging device 220.

[0101] When the carrying clamps 650 of the first carrying device 601 move to the designated height, the fourth driving structure 640 drives the swing connecting frame to swing 90 degrees, thereby driving the plurality of carrying clamps 650 to rotate 90 degrees, so that the heat pipes change from the flat posture to the vertical posture. At the same time, the first driving structure 610 drives the plurality of carrying clamps 650 to move simultaneously in the left-right direction, so that the carrying clamps 650 of the first carrying device 601 move to the positions corresponding to the test clamps 430 of the test clamping device 400, and then the second driving structure 620 of the first carrying device 601 drives the plurality of carrying clamps 650 of the first carrying device 601 to move close to the test clamping device 400.

[0102] After the plurality of carrying clamps 650 of the first carrying device 601 move the heat pipes to the test clamps 430 of the test clamping device 400, the sixth driving structure 420 works to drive the plurality of test clamps 430 to clamp the heat pipes, and then the plurality of carrying clamps 650 of the first carrying device 601 release the clamping of the heat pipes.

[0103] Then the fifth driving structure 410 of the test clamping device 400 works to drive the plurality of test clamps 430 to move downward, so that the lower ends of the heat pipes enter the heating device 300, and the heating device 300 heats the lower ends of the heat pipes. During the heating of the heat pipes by the heating device 300, the feeding device 200 feeds the plurality of heat pipes, the first driving structure 610 drives the first carrying device 601 to reset, and at the same time, the fourth driving structure 640 drives the plurality of carrying clamps 650 to rotate 90 degrees to reset, and the first carrying device 601 waits for the next time to clamp the heat pipes. At the same time when the first driving structure 610 drives the first carrying device 601 to reset, the second carrying device 602 moves to the vicinity of the test clamping device 400.

[0104] After the heating device 300 heats the heat pipes for a certain period of time, the lower ends of the heat pipes reach the set temperature, and the temperature detection head detects the upper ends of the heat pipes, and then the temperature of the upper ends of the heat pipes detected by the temperature detection head is calculated with the temperature of the lower ends of the heat pipes, and whether the temperature difference between the two is within a certain range is used as the basis to judge whether each heat pipe is qualified. Then the fifth driving structure 410 drives the plurality of test clamps 430 to move upward, so that the heat pipes leave the heating device 300. At the same time, the feeding device 200 has arranged the required number of heat pipes for the next test; the screening driving structure 520 drives the inclined feeding structures 510 to move, so that the plurality of inclined feeding structures 510 move to specific positions according to whether each heat pipe is qualified.

[0105] The second driving structure 620 of the second conveying device 602 drives the plurality of conveying grippers 650 to move to the position of the heat pipes and then clamps the heat pipes. After the conveying grippers 650 of the second conveying device 602 clamp the heat pipes, the test grippers 430 release the clamping of the heat pipes. Meanwhile, the conveying grippers 650 of the first conveying device 601 move downward and then clamp the heat pipes arranged in the fixed discharging structure 221.

[0106] After the second conveying device 602 and the first conveying device 601 clamp the heat pipes, the first conveying device 601 repeats the steps of conveying the heat pipes to the test clamping device 400, and the second conveying device 602 is driven by the first driving structure 610 to move to the discharging position.

[0107] After the conveying grippers 650 of the first conveying device 601 are in place, the test clamping device 400 repeats the steps of clamping the heat pipes, and the conveying grippers 650 of the first conveying device 601 repeat the steps of releasing the clamping of the heat pipes and resetting.

[0108] After the second conveying device 602 is in place, the conveying grippers 650 of the second conveying device 602 release the clamping of the heat pipes, and the heat pipes fall to the inclined discharging structure 510 due to their own gravity, the inclined discharging structure 510 guides the heat pipes, so that the qualified heat pipes fall into the qualified product collecting box 101, and the unqualified heat pipes fall into the unqualified product collecting box 102.

[0109] Thus, one working cycle is completed, and the next working cycle is continued.
