[0022] When testing electronic circuit components, the components are conveyed and moved to the lower side of the testing device 13 by the conveyer belt 2 when falling on the conveyer belt 2, so that the components can be tested by the testing device 13, and the testing results are sent to the control cabinet 12 after testing. If the components are unqualified, the control cabinet 12 will start the electric push rod 4 to drive the rack 5 connected to the output end to move, and when the rack 5 moves, the engaged gear one 6 will rotate, and when the gear one 6 rotates, the connected guide plate 7 will rotate, so that the guide plate 7 can rotate to the upper side of the conveyer belt 2 and stop. Then start the servo motor one 8 to drive the shaft 10 connected to the output end to rotate, and drive the guide belt 11 sleeved on the outer circumferential of the two shafts 10 to move through the other shaft 10. At this time, the unqualified components conveyed by the conveyer belt 2 will contact the guide plate 7 and the guide belt 11 on the guide plate 7, and can drive the unqualified components to be conveyed to one side of the base 1 under the guidance of the guide plate 7 and the auxiliary conveying of the guide belt 11. If the components are qualified, the control cabinet 12 will start the electric push rod 4 to drive the guide plate 7 to reset, so that the guide plate 7 is away from the conveyer belt 2. At this time, the qualified components will normally move along the conveyer belt 2 to the front side of the base 1 for collection, so as to achieve the classification and conveying of the tested electronic circuit components, and ensure the accurate discharging of the classified components.

[0023] Reference Figs. 1-3, the dialing assembly is arranged on the outer periphery of the base 1, and is used for dialing when the components are dropped to make them be able to be dropped uniformly. The dialing assembly comprises two dropping plates 14, which are respectively fixedly connected to the front wall of the base 1 and the side of the base 1 away from the support plate 3. The two dropping plates 14 are inclined to the horizontal plane, and the end of the two dropping plates 14 away from the base 1 is lower than the other end of the dropping plate 14. The front part of the base 1 and the side of the base 1 are provided with collecting boxes 16, and the bottom ends of the two dropping plates 14 are arranged in the collecting boxes 16. The bottom walls of the two dropping plates 14 are fixedly connected with supports 17, and the bottom walls of the two supports 17 are fixedly connected with servo motors two 18. The output ends of the two servo motors two 18 are penetrated through the supports 17 and fixedly connected with incomplete gears 19. The outer peripheries of the two incomplete gears 19 are engaged with gear two 20, and the top ends of the two gear two 20 are fixedly connected with dial plates 15. The two dial plates 15 are penetrated through the inner bottom walls of the dropping plates 14, and the bottom ends of the two dial plates 15 are provided with torsional springs 21. One end of the two torsional springs 21 is fixedly connected with the gear two 20, and the other end of the two torsional springs 21 is fixedly connected with the dropping plate 14.

[0024] When the qualified or unqualified components are dropped on the dropping plate 14, the servo motor two 18 is started to drive the incomplete gear 19 fixedly arranged at the output end to rotate. When the incomplete gear 19 is engaged with the gear two 20, the rotation of the incomplete gear 19 can drive the engaged gear two 20 to rotate. When the gear two 20 rotates, the dial plate 15 connected at the top end can swing to one side. When the incomplete gear 19 is disengaged from the gear two 20, the gear two 20 loses the driving force and can be driven by the torsional spring 21 to rotate in the opposite direction. When the gear two 20 rotates in the opposite direction, the connected dial plate 15 swings in the opposite direction, so that the dial plate 15 can swing to both sides, thereby guiding the components dropped on the dropping plate 14 to make the components be able to be dropped uniformly into the collecting box 16, avoiding the components to be accumulated at one place in the collecting box 16.

[0025] Working principle: in actual use process, when the components pass through the test device 13 under the lower side of the conveying belt 2, it will be detected, if the detection is unqualified product, the electric push rod 4 will drive the rack 5 to move and drive the gear one 6 and the guide plate 7 to rotate, when the guide plate 7 rotates to the upper side of the conveying belt 2, through the servo motor one 8 can drive the rotating shaft 10 and the guide belt 11 to rotate, when the unqualified product contacts with the guide plate 7 and the guide belt 11, then it can move along the guide plate 7 to the falling plate 14 on the side of the base 1, when the components are qualified, the guide plate 7 will reset and move away from the conveying belt 2, at this time, the qualified product will move normally along the conveying belt 2 and fall on the falling plate 14 in front of the base 1, at this time, through the servo motor two 18 can drive the incomplete gear 19 to rotate, when the incomplete gear 19 rotates, it will drive the gear two 20 to rotate and the connected push plate 15 to swing, at the same time, it will also pull the torsional spring 21, therefore, after the incomplete gear 19 and the gear two 20 disengage, under the action of the torsional spring 21, it can pull the push plate 15 to swing in the opposite direction, so that the components falling on the falling plate 14 can fall uniformly into the collection box 16.
