[0015] S3: Finally, after the low-temperature test is completed, the chip test seat is moved forward, and two sets of water-absorbing sponges are used to wrap the whole from the pin direction to absorb water stains, and then it is loosened and returned to the test position for high-temperature testing. During high-temperature testing, a small amount of heat comes out through the air outlet box to bake the water-absorbing sponge to prevent it from becoming saturated and affecting the detection work.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Connect the two ends of the connecting pipe to the existing refrigeration and heating equipment respectively, then open the door panel on one side of the shell, pull the slide out along the slide rod, put the required number of vehicle-mounted chips into several groups of chip seats respectively, and then push the slide back to the innermost side. At this time, several groups of clamps are at the outer positions of several groups of chip seats, and the vehicle-mounted chips placed on the inner side can be clamped through the notches on both sides of the chip seats. By using the slide, the detection frame and the two groups of connecting frames are driven to move backward, and the racks set on the connecting frames push the two groups of semi-toothed rings to rotate 180 degrees respectively, and the positioning blocks on the upper sides of the semi-toothed rings are flipped and fitted on the upper ends of the connecting frames. , and the fitting setting after the two sets of positioning blocks rotate, after the detection frame continues to move forward, the connecting frame forms a sliding contact, thereby satisfying the positioning of several sets of clamps, and several sets of clamps move several sets of vehicle-mounted chips forward through the rotation of the two sets of connecting rods, and place them in several sets of chip detection seats installed on the upper side of the detection frame moving to the rear side, and then cooperate with the slide table to drive forward to move to the lower side of the detection shell for detection, and several sets of clamps return to the original position again to prepare for the next set of clamping and picking, avoiding direct manual placement of the chip into the detection seat, which may cause damage due to the temperature retained after the detection, and multiple sets of settings improve the detection effect.

[0018] The detection shell is controlled to move downward by two groups of No. 1 cylinders to cover the outer side of several groups of chip detection seats. At the same time, several groups of positioning springs are pressed on the upper ends of the on-board chips in several groups of chip detection seats to improve the stability of the detection connection. During detection, the environment works in sequence from normal temperature, low temperature, and high temperature.

[0019] When the low-temperature detection is completed, after opening the detection shell, the detection frame and the chip detection seat are moved forward by the slide until they contact the limit rod, and the top frame is pushed in the opposite direction, so that the hollow slider slides in the slide cavity, and the inclined surface lifts the top rod seat and the vehicle-mounted chip in the chip detection seat, and moves to the bottom of the movable rod at the same time, and the fixed rod is controlled to descend by two groups of No. 2 cylinders, and several groups of movable rods first contact the upper end of the vehicle-mounted chip to hold and stabilize it, and then continue to move downward, and the movable rod is pushed to retract toward the fixed tube (the telescopic spring pressure is small), so that the two meshing column gears rotate, and drive the two groups of water-absorbing sponges to wrap the whole from the pin direction to absorb water stains, and then release it, and return to the detection position for high-temperature detection. During high-temperature detection, when the air pipe continues to heat the inside of the detection shell, the electric valve on the branch pipe is opened to allow a small amount of heat to come out through the air outlet box, so that several groups of water-absorbing sponges corresponding to the position of the air outlet box are baked to avoid saturation of the water-absorbing sponges after long-term work, which may affect the detection work.

[0037] The feeding mechanism 5 includes two groups of support plates 51 fixedly arranged on the upper end of the detection platform 1 near the rear side of the U-shaped seat 3, two groups of synchronous wheels 52 are movably arranged on the support plates 51, and the outer sides of the two groups of synchronous wheels 52 are sleeved with synchronous belts 53, and the outer sides of the lower group of the two groups of synchronous wheels 52 are fixedly arranged with a half-toothed ring 54, and the upper and lower ends of the half-toothed ring 54 are fixedly arranged with positioning blocks 55, and one side of the rotating shaft of the two groups of synchronous wheels 52 is fixedly provided with a connecting rod 56, and one side of the two groups of connecting rods 56 is movably provided with a mounting frame 57, and a plurality of groups of clamps 58 are installed on the inner side of the mounting frame 57, and a sliding rod 59 is fixedly installed at the lower side position of the clamp 58 at the upper end of the detection platform 1, and a sliding frame 510 is slidably arranged on the upper side of the sliding rod 59, and a chip seat 511 is fixedly installed at the upper end of the sliding frame 510 corresponding to the positions of the plurality of groups of clamps 58.

After the detection frame 43 continues to move forward, the connecting frame 422 forms a sliding contact, thereby satisfying the positioning of several groups of clamps 58. Several groups of clamps 58 move several groups of vehicle-mounted chips forward through the rotation of two groups of connecting rods 56, and place them in several groups of chip detection seats 45 installed on the upper side of the detection frame 43 moving toward the rear side.

At this time, the several groups of clamps 58 are located at the outer side of the several groups of chip seats 511. The vehicle-mounted chips placed inside can be placed through the notches on both sides of the chip seats 511. The detection frame 43 and the two connecting frames 422 are driven to move backward by the use of the slide 41. The racks provided on the connecting frames 422 push the two groups of half-toothed rings 54 to rotate 180 degrees. The positioning blocks 55 on the upper sides of the half-toothed rings 54 are turned over and fitted on the upper ends of the connecting frames 422. The two groups of positioning blocks 55 are fitted after rotation. After the detection frame 43 continues to move forward, the connecting frames 422 form a sliding contact, thereby satisfying the positioning of the plurality of groups of clamps 58. The plurality of groups of clamps 58 move the plurality of vehicle-mounted chips forward through the rotation of the two groups of connecting rods 56, and place them in the plurality of groups of chip detection seats 45 installed on the upper side of the detection frame 43 moving to the rear side, and then cooperate with the slide 41 to drive forward to move to the lower side of the detection shell 48 for detection, and the plurality of groups of clamps 58 return to the original position again to prepare for the clamping and material taking of the next group, so as to avoid direct manual placement into the chip detection seat 45, which may cause damage due to the temperature retained after the detection, and the multi-group setting improves the detection effect; secondly, the detection shell 48 is controlled to move downward through two groups of No. 1 cylinders 47, and covered on the outer side of the plurality of groups of chip detection seats 45, and at the same time, a plurality of groups of positioning springs 49 are pressed on the upper end of the vehicle-mounted chips in the plurality of groups of chip detection seats 45, so as to improve the stability of the detection connection, and the detection works in sequence from normal temperature, low temperature and high temperature environment, and the two groups of electric valves 413 arranged on the connecting pipe 411 are opened and closed to respectively perform high and low temperature simulation detection in the detection shell 48;When the low temperature detection is completed, after the detection shell 48 is opened, the detection frame 43 and the chip detection seat 45 are moved forward by the slide 41 until they contact the limit rod 420, and the top frame 419 is pushed in the opposite direction, so that the hollow slider 416 slides in the slide cavity 415, and the inclined surface lifts the top rod seat 46 and the vehicle-mounted chip in the chip detection seat 45, and moves to the bottom of the movable rod 431 at the same time. The fixed rod 425 is controlled to descend by two groups of No. 2 cylinders 424, and several groups of movable rods 431 first contact the upper end of the vehicle-mounted chip to press and stabilize it, and then continue to move downward. The movable rod 431 is pushed toward the fixed tube 4 26 retracts and moves (the pressure of the telescopic spring 432 is relatively small), so that the two groups of meshed column gears 428 rotate, driving the two groups of water-absorbing sponges 430 to wrap the whole from the pin direction to absorb water stains, and then loosen it, and return to the detection position for high-temperature detection. During high-temperature detection, when the air pipe 410 continues to heat the inside of the detection shell 48, the electric valve 413 on the branch pipe 412 is opened, so that a small amount of heat can be discharged through the air outlet box 421, so that the groups of water-absorbing sponges 430 corresponding to the position of the air outlet box 421 are baked, so as to avoid the water-absorbing sponges 430 from being easily saturated due to long-term operation, which can easily affect the detection work. ;
