In the embodiment, the second tray temporary storage area 130 has the same structure as the first tray temporary storage area 120, and the difference is that the length of the stop strip 131 is smaller than that of the stop strip 121, and because the second tray temporary storage area 130 is a working area of the end cover on the manipulator grabbing material tray, the stop strip 131 is prevented from interfering with the manipulator by the arrangement; in addition, the second tray temporary storage area 130 only needs to temporarily store one tray at a time, and the smaller length of the stop strip 131 also completely meets the use requirement.
Specifically, when the tray support 164 of the tray loading mechanism 160 moves the tray upwards to the first tray temporary storage area 120, the limiting sheet 143 is retracted under the driving of the limiting power component 142, the limitation of the tray inlet and outlet channels of the first tray temporary storage area 120 is released, the tray support 164 continues to move upwards, so that the tray is lifted to move into the first tray temporary storage area 120, a position sensor is arranged inside, when the tray support 164 moves to a set position, the limiting power component 142 drives the limiting sheet 143 to stretch out, at this time, the limiting sheet 143 is just lifted at the bottom of the tray at the lowest position, the limiting tray is pulled out of the first tray temporary storage area 120, see the tray support 164 (lowest position), the tray support 164' (middle position), the tray support 164″ (highest position) in fig. 3, and when the tray support reaches the highest position, the tray is fed into the first tray temporary storage area 120.
The restricting piece 143 does not interfere with the tray holder 164 when the restricting piece protrudes to hold the bottom of the tray.
Specifically, the working sequence of the tray discharging mechanism 170 and the tray feeding mechanism 160 is opposite, when the trays in the third tray temporary storage area 140 reach the set number or the set height, the tray support moves to the highest position to support the bottom tray bottom, the limiting piece of the third tray temporary storage area 140 retracts, the stacked trays are driven by the tray inlet and outlet channels to move downwards by the tray support to reach the lowest position of the tray support, the trays are supported by the tray placing frame, the second linear dragging mechanism of the tray discharging mechanism drives the tray placing frame to move outwards to realize automatic discharging, and the moved trays are manually removed.
Further, the first tray temporary storage area 120, the second tray temporary storage area 130, and the third tray temporary storage area 140 are sequentially arranged at equal intervals, the distance between the two bracket mechanisms 152 and the distance between the first linear dragging mechanism 151 and the second tray temporary storage area, and the distance between the first linear dragging mechanism 151 and the third tray temporary storage area are equal, so that after the first linear dragging mechanism 151 moves by the initial position (the two bracket mechanisms 152 are located below the first tray temporary storage area 120 and the second tray temporary storage area 130) to the maximum distance, the two bracket mechanisms 152 just synchronously move to below the second tray temporary storage area 130 and the third tray temporary storage area 140, thereby ensuring the high accuracy of transferring, and avoiding the tray transferring fault caused by position error.
The specific transport principle is as follows:
s1: the initial position, two tray brackets are located under the second tray temporary storage area 130 and the first tray temporary storage area 120 in turn (from left to right);
s2: the upper tray moving component 1522 drives the tray 1521 to move upwards to reach the highest position (see the tray 1521' in fig. 2 in detail), at this time, the limiting plates of the first tray temporary storage area 120 and the second tray temporary storage area 130 retract, the tray of the first tray temporary storage area 120 falls onto the tray 1521, the tray positioned in the second tray temporary storage area 130 falls onto the other tray 1521, after a delay setting time, the limiting plates extend, and the tray inlet and outlet channels of the first tray temporary storage area 120 and the second tray temporary storage area 130 are closed;
s3: the bracket 1521 is driven by the pop-up moving assembly 1522 to move down to the initial position;
s4: after the first linear dragging mechanism 151 drives the two brackets 1521 to linearly move to the maximum stroke, the two brackets 1521 translate to the position right below the third tray temporary storage area 140 and the second tray temporary storage area 130;
s5: the upper tray moving component 1522 drives the bracket 1521 to move upwards to reach the highest position, the limiting plates of the second tray temporary storage area 130 and the third tray temporary storage area 140 retract, so that the tray of the first tray temporary storage area is transferred to the second tray temporary storage area, the tray of the second tray temporary storage area is transferred to the third tray temporary storage area, and after the time delay is set, the limiting plates extend out to limit the tray inlet and outlet channels again;
s6: the bracket 1521 is driven by the pop-up moving assembly 1522 to move down to the initial position, and the bracket 1521 is driven by the first linear dragging mechanism to return to the initial position;
s7: the installation steps S2-S6 are cycled.
It should be noted that, when step S7 reaches the execution step S5 of the last cycle of the set number of cycles, the tray feeding mechanism 160 acts to replenish the tray into the first tray temporary storage area; at the same time as step S7 is performed to reach the last cycle of the set number of cycles, the tray discharging mechanism 170 acts to remove the tray in the third tray temporary storage area.
