In addition, the target number of trays of the tray loading part 101 are moved away by the tray moving mechanism 20, and the height of the chuck assembly 202 of the tray moving mechanism 20 is generally unchanged, i.e. the chuck assembly 202 only moves linearly in the horizontal direction, the speed of moving the next tray back to the tray loading part 101 after moving away the tray and placing the tray on the empty tray part 102 is high, the clamping action of the single chuck assembly 202 is simple, the sucking operation of the sucking part 60 can be better matched, and the influence on the next sucking operation of the sucking part 60 and the feeding speed due to the long time for moving away the tray of the tray loading part 101 to the empty tray part 102 and releasing the tray and then returning to the tray loading part 101 is avoided.

As a second aspect of the present application, a retractable plate apparatus 1 is proposed, fig. 6 to 8, which includes the tray conveying device of any one of the embodiments of the first aspect. Furthermore, since the suction unit 60 of the tray transportation device in the first aspect does not serve as a part for removing trays, but only takes charge of the suction operation of plates such as materials, in order to further utilize the efficiency of the suction unit 60, it is considered that in some scenarios, in order to prevent the materials in the uppermost tray of the stacked trays from being contaminated in a single feeding batch, the top of the tray is usually provided with a cover plate to prevent dust from falling to the plate surface, and correspondingly, in order to facilitate the AGV to carry the stacked trays, the bottom of the stacked trays is provided with a bottom plate, which is different from the cover plate, i.e., the cover plate cannot be used as the bottom plate, and the bottom plate cannot be used as the cover plate, so that in the feeding process, the prior art adopts the actions of manually removing the cover plate of the tray part 101 and placing the bottom plate in the empty tray part 102, which affects the automation operation of the device.

Therefore, in the blade housing device 1 according to the second aspect of the present invention, the circulation of the cap plate and the base plate is realized by the suction unit 60 by utilizing the performance of the suction unit 60 in the tray transport apparatus according to the first aspect.

And because the suction portion 60 sucks the upper cover plate of the tray that carries the tray part 101 to stack, the cover plate can not directly place the empty tray part 102 and use as the bottom plate, as an embodiment of the plate collecting and releasing device 1 of this application, the plate collecting and releasing device 1 is provided with the temporary storage station 50, a bottom plate has been placed in advance to the temporary storage station 50, in the feeding process, the suction portion 60 sucks the bottom plate of the temporary storage station 50 to the elevating system 30 of the empty tray part 102, suck the cover plate of the tray part 101 that carries the stacked tray top of waiting to feed to the temporary storage station 50 again, return and carry the tray part 101 and carry out the material loading, after the material loading is accomplished, suck the bottom plate of this batch of tray bottom, can understand, this bottom plate is located carries the elevating system 30 of tray part 101, the suction portion 60 sucks this bottom plate to the temporary storage station 50, and then when the next batch of tray carries out the material loading operation, through a temporary storage station 50 that sets up, accomplish the circulation of bottom plate and cover plate.

Similarly, for the circulation of the cover plate and the bottom plate in the blanking process, the suction part 60 sucks the bottom plate of the temporary storage station 50 to the lifting mechanism 30 of the tray loading part 101, sucks the cover plate on the top of the empty tray stacked on the empty tray part 102 to the temporary storage station 50, returns the empty tray part 102 to transfer the empty tray to the tray loading part 101 to receive the material from the conveying section, and sucks the bottom plate on the bottom of the empty tray of the batch of empty trays 102 to the temporary storage station 50 after the blanking is completed.

Corresponding to the steps S1 to S6 in the first aspect, before the step S1, the bottom plate is placed in the temporary storage station 50, after the step S3 and before the step S4, the suction unit 60 sucks the bottom plate of the temporary storage station 50 to the lifting mechanism 30 of the empty tray part 102, then the bottom plate returns to the tray carrying part 101, sucks the upper cover plate of the uppermost tray to the temporary storage station 50, and after the batch of trays are completely loaded and are moved to the empty tray part 102 by the tray moving mechanism 20, the suction unit 60 sucks the cover plate of the temporary storage station 50 to the position above the empty tray of the empty tray part 102, and sucks the bottom plate of the batch of trays located in the tray carrying part 101 to the temporary storage station 50.

Further, the efficiency of the suction part 60 of the tray conveying device in the first aspect is utilized, and the circulation of the bottom plates and the cover plates of trays in different batches can be completed by the plate collecting and releasing device 1 only on the premise of setting a temporary storage station 50.

It should be noted that each batch of stacked trays only includes a bottom plate and a cover plate, and the sucking part 60 sucks the two plates does not affect the efficiency of loading the single batch of trays.

Since the plate storing and taking apparatus 1 according to the second aspect needs to suck the material, that is, the PCB, and the cover plate and the bottom plate, referring to fig. 5, in order to avoid the sucking of the cover plate and the bottom plate from interfering with the sucking of the PCB, the chuck assembly 602 of the sucking part 60 includes a first chuck assembly 6021 for sucking the cover plate or the bottom plate and a second chuck assembly 6022 for sucking the material in the tray, the first chuck assembly 6021 is provided with a telescopic structure 6023 along the sucking direction, generally, the cover plate and the bottom plate are larger than the material size, so the first chuck assembly 6021 can be generally disposed at the periphery of the second chuck assembly 6022, when the sucking part 60 sucks the material, the first chuck assembly 6021 keeps in a retracted state to avoid contacting the PCB, and when the sucking part 60 sucks the cover plate and the bottom plate, the first chuck assembly 6021 extends.
