The fixed plate 7 is provided with a through hole for fixing the suction disc group. A bulk material distribution mechanism is arranged on the rack 1 close to the upper supporting mechanism. The bulk material distribution mechanism includes a material distributor 13 electrically connected with the control system. The material distributor 13 belongs to the prior art. A bulk material distribution plate 14 is screw-fixed at the material outlet position of the material distributor 13. A first tray pushing mechanism 15 is arranged on the rack 1 between the upper supporting mechanism and the bulk material distribution mechanism. When the tray moves to the bulk material distribution mechanism along the length direction under the action of the first tray pushing mechanism 15, the bulk material distribution mechanism transfers a set amount of materials to the tray through the bulk material distribution plate 14, and the scattered materials are symmetrically stacked in the tray on the side close to the bulk material distribution plate 14. A conveying belt for driving the tray to move is arranged on the rack 1 between the first tray pushing mechanism 15 and the bulk material distribution mechanism. The conveying belt includes two parallel belt wheel mechanisms 20 electrically connected with the control system. The belt wheel mechanisms 20 belong to the prior art and are bolted with the rack 1 through a frame. The belt wheel mechanisms 20 include a wheel body and a belt 21. Two belts 21 are screw-fixed with cross bars 22. The cross bars 22 are uniformly arranged along the length direction of the belt 21. Adjacent cross bars 22 are arranged in parallel to form a placing area for placing the tray. An accumulation area 16 is arranged on the rack 1. The rotating roller 19 in the accumulation area 16 is arranged obliquely. After the tray passes through the accumulation area 16 arranged obliquely, part of the stacked materials will move to the opposite side of the tray under the action of gravity. A second tray pushing mechanism 17 is arranged on one end of the rack 1 close to the accumulation area 16. The first tray pushing mechanism 15 and the second tray pushing mechanism 17 have the same structure and both include a motor electrically connected with the control system. A ball screw mechanism is arranged on the rack 1. The motor is connected with the ball screw mechanism through a shaft coupling. A push plate for pushing the tray to move is bolted with the slider of the ball screw mechanism.The rack 1 is provided with a conveying belt 18 at one end, and the conveying belt 18 is arranged below a rotating roller 19. When the tray is transferred to the conveying belt 18 by the second tray pushing mechanism 17, the materials in the tray will be dispersed and spread along the length direction of the tray under the action of vibration.

[0020] In an embodiment, according to the accompanying drawings Figures 3-5 As shown, the suction cup group includes a first suction cup group 9 and a second suction cup group 10, and the first suction cup group 9 and the second suction cup group 10 each include a vacuum suction cup 11 fixed on the fixed plate 7, and the vacuum suction cup 11 is fixed on the fixed plate 7 at one end through a through hole. The first suction cup group 9 is arranged along a straight line passing through the center of the fixed plate 7, and the vacuum suction cup 11 of the first suction cup group 9 is at least three. The second suction cup group 10 is arranged at both sides of the straight line where the first suction cup group 9 is located and close to the corner position of the fixed plate 7, and the vacuum suction cup of the second suction cup group 10 is at least two. The distance between the end of the vacuum suction cup 11 of the first suction cup group 9 and the second suction cup group 10 and the fixed plate 7 is different. When the vacuum suction cup 11 adsorbs the tray, the vacuum suction cup 11 of the second suction cup group 10 will drive the two opposite corners of the tray to be lifted up under the support of the first suction cup group 9. The suction cup group further includes a vacuum generator used in cooperation with the vacuum suction cup 11. The vacuum suction cup 11 includes a rod body and a suction cup body 12, and a spring is arranged on the rod body and extends from the rod body to one end of the suction cup body 12 away from the rod body. The elastic coefficient of the spring on the suction cup body 12 of the first suction cup group 9 is greater than that of the second suction cup group 10. A damping block is screw-fixed on the edge of the main bin 2 of the rack 1 through a connecting rod, and the side of the damping block close to the tray is in a stepped structure. When the double-tray condition occurs, the lower tray is separated from the upper tray under the block of the damping block.

[0021] In an embodiment, according to the accompanying drawings Figure 8 As shown, the bulk material plate 14 includes a fixed rod 23 screw-fixed at the material outlet position of the distributor 13, and the fixed rod 23 is provided with a bending plate 24 arranged obliquely and used for guiding the material. The bending plate 24 is at least two and arranged in parallel with each other along the width direction of the tray. The length of each bending plate 24 decreases in turn, the cross section of the bending plate 24 is in an "L" shape structure, and the width of one side of the bending plate 24 is equal to the width of the material. After the material enters the bulk material plate 14, the material will be guided. Because the flow is large, a small part of the material will flow into the tray along the first layer of the bending plate 24, and most of the material will fall into the tray along the bending plate 24 with gradually decreasing length, and the uniformity of the distribution is ensured.

[0022] The implementation principle of the automatic bulk material tray loading, receiving and queuing equipment provided in the embodiments of the present application is as follows: The cleaned trays are stacked in batches on the bearing plate 3 of the main bin 2, and a set number of standby trays are placed in the auxiliary bin 5. After starting the device, the control system sends a command to the jacking mechanism 4, the servo motor drives the ball screw module, and the bearing plate 3 with the trays moves upward. When the distance sensor detects that the uppermost tray reaches the adsorption station, the jacking mechanism 4 stops moving. The horizontal moving module 6 drives the adsorption assembly to move above the main bin 2, and the push rod motor 8 receives the control system command and outputs the shaft downward, driving the fixed plate 7 and the suction cup group to move downward synchronously until the vacuum suction cups 11 of the first and second suction cup groups 9 and 10 are attached to the upper surface of the tray. After the push rod motor 8 is extended to the position, the control system triggers the vacuum generator to start, and a negative pressure is formed in the vacuum suction cup 11 to firmly adsorb the tray. Then, the output shaft of the push rod motor 8 is retracted upward, driving the suction cup group and the tray to move upward synchronously. Since the spring length of the first suction cup group 9 is longer, the vacuum suction cups 11 of the second suction cup group 10 are retracted before the first suction cup group 9, thereby driving the two opposite edges of the tray to be raised upward, forming a clear gap between the tray and the adjacent tray below, and completely separating the adhesion. During the upward movement of the tray, the stepped silica gel block at the edge of the main bin 2 contacts the bottom of the tray, and the stepped structure of the silica gel block provides frictional damping. Even if there is a slight adhesion tendency of the tray below, it will be blocked by the silica gel block and cannot rise with the tray above, further ensuring that there is no double tray.

[0023] Under the cooperation of the control system, the rotating roller 19 drives the tray to move to the first tray pushing mechanism 15, and pushes the tray to the placement area composed of the two horizontal rods 22 and the belt 21. When the tray moves below the distribution plate 14, the distributor 13 discharges, and the materials are stacked on one side of the tray close to the distributor 13 and symmetric about the distribution plate 14. After a set amount of material flows into the tray, the conveyor belt transfers the tray to the buffer area. The rotating roller 19 in the buffer area is inclined, and part of the material slides away from the distributor 13 under the action of its own gravity. The second tray pushing mechanism 17 at the end of the buffer area pushes the tray to fall onto the conveyor belt 18, and the materials in the tray are dispersed and spread on the tray. The cylinder 25 for stopping the tray is arranged on the conveyor belt 18, and rises after receiving the signal of the control system. The tray is collected into the main feeding line under the action of the conveyor belt 18.

[0024] When the trays in the main bin 2 gradually decrease and the bearing plate 3 rises to the highest limit, the control system determines that the trays in the main bin 2 are insufficient, triggers the auxiliary bin 5 switching program, and the horizontal moving module 6 immediately drives the adsorption assembly to move above the auxiliary bin 5. Since the auxiliary bin 5 does not need to be jacked up, the upper surface of the tray is already at the adsorption station, and the push rod motor 8 directly extends to adhere to the tray surface and adsorb. During the tray supply in the auxiliary bin 5, the operator supplements a batch of trays into the main bin 2.

[0025] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
