[0041] refer to Figure 1 , Figure 1 This is a perspective view of a material tray feeding device based on intelligent control according to this application. Figure 1 As shown, a material tray feeding device based on intelligent control includes a material tray device 10, a feeding device 20, an empty tray device 30, and a conveyor belt device 40, which are arranged in sequence along a preset direction: material tray device 10, feeding device 20, and empty tray device 30.

[0042] Continue to refer to Figure 1 Please refer to them together. Figure 2 and Figure 3 , Figure 2 This is a partial structural diagram of the tray mechanism in a tray feeding device based on intelligent control according to this application. Figure 3 This is a perspective view of a material tray feeding device based on intelligent control, as described in this application. Figure 1 , Figure 2 and Figure 3 As shown, the area where the tray device 10 is located is the full tray area 11. The tray device 10 includes a suction nozzle mechanism 12 and a tray mechanism 13. The suction nozzle mechanism 12 is always located directly above the tray mechanism 13 and moves up and down along the Z direction. The tray mechanism 13 forms a receiving space 14. The tray mechanism 13 is driven by a screw lifting device (not shown in the figure) to move the tray up and down inside the receiving space 14. Furthermore, the suction nozzle mechanism 12 includes six vacuum suction nozzles 121. Four vacuum suction nozzles 121 correspond to the four corners of the tray, and the remaining two vacuum suction nozzles 121 correspond to the middle positions of the two opposite edges of the tray. Through four-point suction combined with the suction of the two middle points, the tray is prevented from tilting during the conveying process, effectively improving the material handling efficiency. The stability of the pallet conveying process is improved, and the tilting of the workpiece is avoided during the conveying process. Specifically, the pallet is gradually raised from the bottom of the receiving space 14 in the pallet mechanism 13 by the screw lifting device until it reaches the designated height. Then, the rising stops and waits for the suction nozzle mechanism 12 to adsorb the pallet through the vacuum suction nozzle 121. After that, the suction nozzle mechanism 12 descends along the Z direction to adsorb the pallet. After the suction nozzle mechanism 12 has firmly adsorbed the pallet, the screw lifting device drives other pallets to descend, so that the adsorbed pallets leave the pallet mechanism 13. This effectively improves the stability of the pallet lifting process and the accuracy of stopping at the designated position. It should be noted that the full pallet area 11 is used to store pallets containing workpieces, and the pallets are gradually raised to the designated position along the Z direction by the screw lifting device.

[0043] Continue to refer to Figure 1 , Figure 2 and Figure 3 Please refer to them together. Figure 7 , Figure 7 This is a structural diagram of the material tray in a material tray feeding device based on intelligent control, as described in this application. Figure 1 , Figure 2 , Figure 3 and Figure 7The area where the feeding device 20 is located is the feeding area 21. The feeding device 20 includes a feeding platform 22 and a gripper mechanism 23. The feeding platform 22 moves along the X direction, and the gripper mechanism 23 moves up and down along the Z direction. Specifically, the feeding platform 22 is an electric slide table. The feeding platform 22 moves back and forth between the full tray area 11 and the empty tray area 31. The feeding platform 22 moves to the full tray area 11 and is located directly below the suction nozzle mechanism 12. After the feeding platform 22 carries the tray 41 adsorbed by the suction nozzle mechanism 12, it moves to the feeding area 21 and makes the tray 41 just below the gripper mechanism 23. The gripper mechanism 23 grips the workpieces in a tray 41 in a single-row batch gripping manner. The column width between adjacent columns is L. After each column of workpieces is gripped, the feeding platform 22 carries the tray 41 and moves a distance L towards the empty tray area 31 until all the workpieces in the tray 41 are gripped. Specifically, after the gripper mechanism 23 grips the first row of workpieces, it moves above the conveyor belt and then descends to place the workpieces on the conveyor belt device 40. The gripper mechanism 23 uses an intermittent gripping method to ensure the distance between workpieces after loading, avoiding errors in the inspection and photography process caused by workpieces being too close together. For example, after the gripper mechanism 23 grips the first batch of five workpieces in the first row and places them on the conveyor belt device 40, it moves back to the first row to grip the remaining five workpieces. Here, the column-by-column gripping by the gripper mechanism 23, combined with the electric slide table, can precisely control the position of the tray 41 and realize column-by-column loading of workpieces, effectively improving the gripping accuracy and avoiding gripping deviation, thereby effectively improving the loading accuracy. In addition, the reciprocating movement of the loading platform 22 between the full tray area 11 and the empty tray area 31 can be achieved by the cooperation between the sliding rod and the sliding head, as long as there is no interference between the devices.

[0044] Continue to refer to Figure 1 Please refer to them together. Figure 4 , Figure 5 and Figure 6 , Figure 4 This is a perspective view of the gripper head in a material tray feeding device based on intelligent control according to this application. Figure 5 This is a structural diagram of the gripping part of the gripper head in a material tray feeding device based on intelligent control according to this application. Figure 6 yes Figure 4 An enlarged view of circle A shown. Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the gripper mechanism 23 includes a set of gripper assemblies 24, which are connected via gripper support assemblies (not shown). The gripper support assemblies are connected to a gripper power device (not shown), thereby enabling the gripping of the workpiece. Each set of gripper assemblies 24 includes five sets of gripper heads 25, with each set of gripper heads 25 including two gripper heads 25 positioned opposite each other. Each gripper head 25 has an adjustment hole 251, through which an adjustment rod 252 passes. A positioning ring 253 is provided on the adjustment rod 252. Furthermore, the adjustment rod 252 adjusts... The interior of hole 251 can freely expand and contract. The adjusting rod and positioning ring are fixedly connected to ensure that during the gripping operation of the two gripper heads 25, the adjusting hole 251 and adjusting rod 252 always cooperate, and the adjusting hole 251 always moves along the adjusting rod 252. The positioning ring 253 limits the gripping position of the gripper heads 25 during the gripping operation, thus physically limiting the return distance of the gripper heads 25. This effectively avoids excessive return distances of the gripper heads 25 due to malfunctions in the gripping power device or errors during debugging, which could damage the workpiece. Over-clamping can lead to batch damage of workpieces during production, causing incalculable economic losses. It is also capable of handling materials of different specifications. It should be noted that when different gripper mechanisms or materials of different specifications need to be matched, by selecting an adjusting rod 252 of appropriate position and length for the positioning ring, and passing it through the adjusting hole 251 through the gripper head 25, the gripper head 25 is fixed to the corresponding power mechanism. This achieves the connection between the gripper head 25 and the adjusting rod 252 and positioning ring 253, as well as the connection between the gripper head 25 and the power mechanism. In addition, the fixed connection between the positioning ring 253 and the adjusting rod 252 includes, but is not limited to, welding; furthermore, the gripper head 25 includes a connecting part 254 and a gripping part 255. The connecting part 254 is provided with a connecting hole 256, which is connected to the gripper support assembly. The inner side wall of the gripping part 255 is provided with a protective layer 257. The setting of the protective layer 257 effectively avoids rigid contact between the workpiece and the gripping part 255, and reduces the scrap rate of the gripper mechanism 23 during operation. It should be noted that the material of the protective layer 257 includes, but is not limited to, rubber.

[0045] Continue to refer to Figure 1 , Figure 2 and Figure 3The empty tray device 30 stores empty trays after the loading device 20. The area where the empty tray device 30 is located is the empty tray area 31, which stores empty trays after workpiece clamping. The empty tray device 30 has the same structure as the tray device 10. After moving to the empty tray area 31 via the loading platform 22 and facing the suction mechanism 12 in the empty tray device 30, the suction mechanism 12 picks up the empty tray. The loading platform 22 returns to the loading area 21, and the tray mechanism 13 in the empty tray device 30 rises. At this time, the suction mechanism 12 in the empty tray device 30 places the empty tray onto the tray mechanism 13. The tray mechanism 13, driven by the screw lifting device, descends into its receiving space 14. The conveyor belt device 40 faces the discharge end of the loading device 20. Here, the intelligent control-based tray feeding device includes a tray device 10, a feeding device 20, and an empty tray device 30. The tray device 10 includes a suction nozzle mechanism 12 and a tray mechanism 13. The suction nozzle mechanism 12 is always located directly above the tray mechanism 13 and moves vertically along the Z direction. The feeding device 20 includes a feeding platform 22 and a gripper mechanism 23. The feeding platform 22 moves along the X direction, and the gripper mechanism 23 moves vertically along the Z direction. The tray device 10, feeding device 20, and empty tray device 30 are arranged sequentially along a preset direction. This effectively improves the convenience and efficiency of tray conveying during operation, enhances automation, and reduces labor costs. Furthermore, the positioning device on the loading platform 22 improves the accuracy of the tray position, preventing tilting of the tray during transfer and thus avoiding workpiece misalignment or displacement. Through signal transmission between the external sensing device and the tray device 10, loading device 20, empty tray device 30, and conveyor belt device 40, the processes of workpiece clamping, tray and workpiece transfer, and workpiece placement on the conveyor belt device 40 are automated. The close connection between each station greatly reduces manual intervention and effectively improves production efficiency. The alternating operation of the suction nozzle mechanism 12 and the gripper mechanism 23 further ensures continuous and reliable operation of the production line, eliminating waiting time and further improving production efficiency.

[0046] refer to Figure 8 , Figure 8 This is an internal structural diagram of the gripping section in a material tray feeding device based on intelligent control, as described in this application. Figure 8As shown, the gripper head 25 has a through hole 265 at the bottom of its gripping part 255. The elastic assist support mechanism 26 includes a support rod 261 and a ball bearing 262 connected to the support rod 261. One end of the support rod 261 is connected to a limiting piece 263, and the other end is connected to the ball bearing 262. The limiting piece 263 is also provided with a positioning post 264, and the positioning post 264 and the support rod 261 are located on opposite sides of the limiting piece 263. The top of the storage groove 255A is also provided with a positioning post 264. A compression spring 266 is connected between the two positioning posts 264. The support rod 261 passes through the through hole 265 into the storage groove 255A, and the support rod 261 can freely extend and retract along the through hole 255A. The limiting piece 263 is located inside the storage groove 255A. The rolling ball 262 is located outside the receiving groove 255A. One end of the compression spring 266 abuts against the inner wall of the receiving groove 255A, and the other end abuts against the limiting piece 263. This enables the gripping part 255 of the gripper head 25 to grip the workpiece during operation. After each set of gripper heads 25 grips one workpiece, the elastic assist support mechanism 26 can provide corresponding auxiliary force when the workpiece is removed from the groove of the material tray, which facilitates the removal of the workpiece. Under the action of the rolling ball 262, it is convenient for the gripper head 25 to grip with elastic support, reducing frictional resistance and preventing the workpiece from being stuffed too tightly into the groove of the material tray, making it impossible to remove the workpiece and causing some sets of gripper heads 25 to run empty. This effectively improves the convenience of the working process.

[0047] Furthermore, by adjusting the distance between a set of gripper heads 25 in the gripper mechanism 23, the gripping of workpieces of different specifications can be met. By adjusting the distance between the vacuum nozzles 121 in the suction nozzle mechanism 12, the handling of trays of different specifications can be adapted. In addition, the tray gradually rises from the bottom of the receiving space 14 in the tray mechanism 13 through the screw lifting device until it reaches the specified height, then stops rising and waits for the suction nozzle mechanism 12 to adsorb the tray through the vacuum nozzles 121. After that, the suction nozzle mechanism 12 descends along the Z direction to adsorb the tray. After the suction nozzle mechanism 12 has firmly adsorbed the tray, the screw lifting device drives other stacked trays to descend, so that the adsorbed trays leave the tray mechanism 13. The gripper mechanism 23 and the loading platform 22 in the loading device 20 move to the full tray area 11 and are located directly below the suction nozzle mechanism 12. The suction nozzle mechanism 12 descends and accurately places the tray on the loading platform 22 in the loading area 21.
