In the actual test process, generally only a few test stations with small numbers are working, and other test stations with large numbers are idle. The utility model utilizes this feature, firstly, the heating part 5 is placed on the workstation in the order of the workstation number from small to large, so that it replaces the original test workstation, and then the test workstation kit of the original test workstation is placed on the subsequent large-numbered test workstation, so that the device to be tested can be heated first, and then tested, and the heating test work of the device to be tested is completed; the heating part 5 is installed on the support used in the original workstation by bolts, and then a plurality of supports with the heating parts installed are pushed into the front plurality of workstations of the sorting machine along the slide rails on the table of the sorting machine, so that the heating part 5 can be located at a predetermined precise position, so that the nozzle can be automatically aligned with the device to be tested, so that the hot air nozzle 6 The effective heating area is larger than the test area of ​​the original workstation. The device sets a first flexible butt joint pipe 45, so that the hot air pipe 56 of the heating part 5 can be easily and quickly plugged into one end of the first flexible butt joint pipe 45, so as to realize plug-and-play of the device.

The heating part 5 further includes a temperature sensor 54 provided on the side of the second wind cavity 53, and a sensor wire 55 connected to the temperature sensor 54. The other end of the sensor wire 55 is connected to a test station in the sorter, and the test station is connected to an external independent testing machine. By providing the wind cavity, the hot air can travel or turn along a predetermined area and finally be ejected from the hot air nozzle 6. By providing the temperature sensor 54, when the air source cylinder 3 used is a constant temperature heat source, at this time, the temperature sensor 54 can transmit the detected temperature information to the test part at other workstations of the turret through the sensor wire 55, and then the test part transmits it to the external independent testing machine. Then, the testing machine instructs the operation of the turret sorter according to the detected temperature value, making the device to be tested rotate idly or continue to be heated, thereby adjusting the heating duration of the device to be tested. When the air source cylinder 3 used is a heat source that can receive external temperature control, the sensor can transmit the detected temperature information to the test part at other workstations of the turret through the sensor wire 55, and then the test part transmits it to the external independent testing machine.

[0043] The adjustable chassis 1 includes a base 11, four height adjustment rods 12 screwed to the base 11, and anti-slip feet 13 provided at the bottoms of the height adjustment rods 12; due to the characteristic that the slide rail of the turret sorter is radially shaped, anti-slip foot pads of different sizes can be used. The outer diameters of the two foot pads closer to the heating part 5 are slightly smaller, and the diameters of the two foot pads in the opposite direction closer to the end of the air source cylinder 3 are slightly larger. By adjusting, the height of the base 11 is adjusted to complete the alignment adjustment between the conversion part and the heating part 5.

[0045] An isolation grid is also provided in the hot air nozzle 6. The isolation grid is in a shape of a straight line, a cross or a mesh to prevent the device to be tested being heated from falling into the air nozzle.

[0046] Description of the working principle: Modern turret test sorters generally have 8 or more test stations. The test stations are numbered in ascending order according to the direction of rotation of the sorting disk. During the actual test process, generally only a few test stations with small numbers are working, and the other test stations with large numbers are idle. The present utility model utilizes this feature. First, the heating part 5 is placed on the stations in ascending order of the station numbers, replacing the original test stations. Then, the test station kits of the original test stations are placed on the subsequent test stations with large numbers, so that the device to be tested can be heated first and then tested, completing the heating and testing work of the device to be tested. The heating part 5 is installed on the support used in the original station through bolts. Then, multiple supports with the heating parts installed are pushed into the front multiple stations of the sorter along the slide rails on the sorter table, so that the heating part 5 can be located at a predetermined precise position, enabling the nozzle to automatically align with the device to be tested, and making the effective heating area of the hot air nozzle 6 larger than the test area of the original station. Then, the adjustable chassis 1 is placed at a predetermined position, and the height of the base 11 is adjusted respectively to align and adjust the conversion part with the heating part 5. Then, the air source cylinder 3 is placed between the upper clamp seat 22 and the lower clamp seat 21 and abuts against the support seat 14. Then, the installation work of the air source cylinder 3 is completed through the bolt locking member 23 and the connecting bolts. Then, the manifold 44 and the hot air pipe 56 are respectively inserted into the first flexible docking pipe 45. Then, the air source cylinder 3 starts to work. Thus, hot air can enter the air cavity along the air outlet end of the air source cylinder 3, the pressure regulating cavity 46, the manifold 44, the first flexible docking pipe 45, and the hot air pipe 56. Then, the flow direction of the hot air is changed through the first air cavity 52 and the second air cavity 53 in the air cavity, so that the hot air is ejected from the hot air nozzle 6, completing the heating work of the device to be tested. The temperature sensor 54 can finally transmit the temperature information to the test machine. Then, the test machine issues different instructions according to the type of the air source cylinder 3, so that the device to be tested can be heated to a predetermined temperature. Then, through the rotation of the sorter, it is located at the test position, and the performance of the heated device to be tested is tested by the original test equipment.
