Embodiment 2

[0046] Based on the first embodiment, Figure 1-Figure 9 As shown, in a preferred embodiment of the present invention, a loading and unloading method of an automatic loading and unloading machine of a placement machine comprises the following steps:

[0047] Adjust the receiving spacing of the silo 16 and the conveying spacing of the front-stage feeding streamline body 2 and the lifting and taking-up mechanism assembly 3 according to the carrier plate 162;

[0048] The material bin 16 loaded with several layers of carrier plates 162 is pushed into the loading window 15 of the frame 1 and introduced into the conveying mechanism 22 of the front feeding streamlined body 2 of the frame 1. The material bin 16 is conveyed to the set position by the displacement of the conveying mechanism 22, and the position of the material bin 16 on the front feeding streamlined body 2 is limited by the positioning component;

[0049] The mounting seat 31 in the lifting and picking mechanism assembly 3 is driven to move to the picking position, the carrier pull rod 34 in the adjustable picking mechanism is driven to drive the shifting block 341 to move to the specified position in the silo 16, the lifting frame 38 is driven to drive the adjustable picking mechanism to move downward, the shifting block 341 abuts against one end of the carrier plate 162, and the reciprocating material shifting mechanism drives the carrier pull rod 34 to pull the carrier plate 162 into the transmission channel to realize the loading operation.

[0050] The longitudinal material position of the adjustable material taking mechanism is adjusted sequentially by lifting the material taking mechanism assembly 3 to achieve alignment with the position of the carrier plate 162 on the material bin 16 received by the front-stage feeding streamline body 2;

[0051] The carrier plate 162 is transferred to the subsequent workstation through the transmission channel. After the carrier plates 162 in the bin 16 are loaded with materials, the bin 16 is released through the positioning component of the front-stage feeding streamline body 2, and the conveying mechanism 22 is driven to reversely convey and withdraw the bin 16. Embodiment 3

[0052] On the basis of Example 1 or Example 2, Figure 8 , Fig.10As shown, a lateral displacement mechanism 37 is arranged on the upper part of the gantry 36, and a lifting frame 38 capable of longitudinal lifting is arranged on the lateral displacement mechanism 37, and a reciprocating material shifting mechanism 40 is arranged on the lifting frame 38, and the reciprocating material shifting mechanism includes a mounting plate arranged on the lifting frame 38, and a transmission mechanism is arranged on the mounting plate, and a carrier pull rod 34 is driven and arranged on the transmission mechanism, and the carrier pull rod 34 is provided with spaced downwardly extending shifting blocks 341, and the interval width of at least one carrier plate 162 is reserved between the spaced shifting blocks 341; two shifting blocks 341 are arranged, and one shifting block 341 is convenient for pulling out the carrier plate 162, and the other shifting block 341 is convenient for pushing back the carrier plate 162. The shifting height of the shifting block 341 between the carrier plates 162 is adjusted by the lifting frame 38, so as to adjust the shifting height of the carrier plates 162; it is convenient to take out the carrier plates 162 and store the empty carrier plates 162 after taking out the materials. Furthermore, the rack 1 is also provided with an air source connector 11 for providing an air source to the cylinder in the device, the rack 1 is also provided with a power supply interface 12 for providing electric energy to the device, and the rack 1 is also provided with a detachable maintenance door 14.

[0053] Working principle:

[0054] like Figure 1-Figure 10 As shown, the AGV cart in the prior art drags the bin 16 with the carrier tray 162 for placing stacked products to the position of the loading window 15, stops, and then starts to lift the bin 16 to a specified height through the lifting mechanism in the prior art and then pushes it forward. When the bin 16 with the carrier tray 162 carrying the products just enters the loading window 15, the bin entry sensor 23 senses that the bin 16 has just entered, and the conveying mechanism 22 drives the conveyor belt 224 to rotate and move the bin 16 forward. When the front bin limit sensor 24 senses that the bin 16 has just reached its position, the conveyor belt 224 stops rotating. At this time, the bin 16 stops, and the two rough positioning cylinders 25 begin to extend to prevent the bin 16 from moving forward and backward, playing a role of front and rear limiting. Then the two fine positioning cylinders 26 and the limit pin 296 are inserted into the positioning holes corresponding to the bin 16, so that the bin 16 is completely fixed and cannot move forward and backward.

[0055] At this time, the electric slide 32 in the front lifting and picking mechanism assembly 3 starts to rise with the mounting seat 31. Because the electric slide 32 is controlled by a servo motor, the electric slide 32 can stop at any height with the mounting seat 31 during the rising process. Because the carrier plate 162 in the silo 16 has a spacing of 12 mm between each layer of the carrier plate 162, the conveyor belt can be accurately aligned with the rear carrier plate 162. After alignment, the carrier pull rod 34 is moved from the first layer of the carrier plate 162 in the silo 16. Initially, each stack of carrier trays 162 loaded with products is pulled out from top to bottom onto the conveyor belt in the lifting and picking mechanism assembly 3. When the carrier in place detection optical fiber sensor detects that the carrier tray 162 is transferred to the conveyor belt, the conveyor belt stops moving. At the same time, the front and rear stop assemblies 39 extend the stop rods downward to limit the carrier tray 162. When the stop assembly 39 retracts, the carrier tray 162 begins to flow into the next workstation under the action of the conveyor belt, thereby completing the whole set of actions of the loading and unloading machine.
