The main actions of the handling system 1 include a handling action and a pulling action. The traction action pulls the jig 4 in the bin body to the traction device 14, and the jig 4 on the traction device 14 can also be pulled into the bin body. The conveying system 1 performs conveying actions, including feeding conveying and discharging conveying, for example, when feeding conveying, the movable frame 12 moves along the X-axis guide rail assembly 11, the lifting platform 13 performs lifting movement to find the position in the X-axis direction and the Z-axis direction of the conveying bin 3112, the traction device 14 pulls the jig 4 in the conveying bin 3112 to the conveying position of the traction device 14, and then the position of the ageing bin 3111 in the X-axis direction and the Z-axis direction is found by the movable frame 12 and the lifting platform 13. After locating the X-axis and Z-axis positions of the ageing oven 3111, the traction device 14 is aligned with the ageing oven 3111 to draw the jig 4 into the ageing oven 3111. When carrying out the ejection of compact transport, the transport system 1 aims at ageing storehouse 3111 in the position of X axis, Z axial direction, carries the tool 4 in this ageing storehouse 3111 to conveying storehouse 3112 to realize ejection of compact transport.

In addition, in order to avoid interference between the lifting platform 324 and the conveying limiting assembly 325, an avoidance gap is further formed on one side of the bearing platform 3243 in the conveying direction, where the avoidance gap makes the plane parts of the guide plate and the bearing platform 3243 have gaps. The lifting mechanism is located at the avoidance gap after lifting, so that the lifting platform 324 and the conveying limiting assembly 325 can independently act on the jig 4 to avoid mutual interference.

The ingress and egress of the jig 4, particularly the ingress and egress of the jig 4, generally requires the first conveyor 32, the lift-up platform 324 and the transfer stop assembly 325 to cooperate, one of which is as follows.

When the external transfer device transfers the jig 4 onto the first transfer device 32, the lifting platform 324 descends, so as to prevent the lifting platform 324 from blocking the movement of the jig 4.

The jig 4 sequentially moves towards the transfer stations of the first conveying component 322, and the conveying limiting component 325 is lifted to limit the position of the jig 4 before the jig 4 enters the corresponding transfer station until each transfer station is sent into the jig 4.

The first conveyor 32 is deactivated. The external conveying mechanism stops conveying the jig 4. Alternatively, in the feeding conveyor, the conveying limiting component 325 of the first conveying component 322 close to the external conveying mechanism is lifted up to limit the subsequent fixture 4 to be fed continuously.

The lifting platform 324 is lifted up to lift the jig 4 above the guard 3236. The transfer stop assembly 325 in the transfer direction of the transfer station is lowered. Then, the transporting system 1 transports the jig 4 into the ageing bin 3111.

In the process of delivering the jig 4, the first conveying device 32, the lifting platform 324 and the conveying limiting assembly 325 are also required to cooperate with each other, wherein one of the cooperation modes is as follows.

The lift platform 324 is raised and the transfer stop assembly 325 lowered prior to removal from the burn-in cartridge 3111. The handling system 1 carries the jig 4 onto the lift platform 324 of the transfer bin 3112. Then, the lifting platform 324 descends, and the first conveying device 32 conveys the jig 4 to the external conveying mechanism.

In addition, in the present embodiment, the limit projection on the carrying mechanism and the check mechanism 314 limit the position of the jig 4, so that the jig 4 and the electronic product can be accurately stopped in the ageing bin 3111.

Of course, to control the temperature of the ageing cabin 3111, the load ageing assembly further comprises a temperature sensor, which may be provided with an air outlet or a carrying mechanism, or may extend directly above the ageing cabin 3111.

The two groups of bearing mechanisms bear the jig 4 and the electronic products on the jig 4 from the two sides of the ageing bin 3111, and when the electronic products are fixedly placed through the jig 4, the two groups of bearing mechanisms bear the work.

In addition, because the bearing mechanism bears the jig 4 by the roller, the friction force borne by the jig 4 is smaller and the jig 4 is easier to move, and the limiting protrusion and the non-return mechanism 314 can limit the jig 4 on the roller, so that the jig 4 is prevented from moving on the roller during the aging test.

The distance between the limiting block and the first end face is smaller than L, in other words, the limiting block is arranged between the pivot shaft and the first end face. When the check block rebounds, the second end of check block upwards swings for the second end protrusion of check block is in the check seat, and the stopper then downwards swings, makes the bottom of stopper butt mounting groove, thereby restricts the protrusion height of check block, avoids the check block to receive the elastic component influence and excessively kick-backs.
