[0002] The robot feeding detection equipment needs to efficiently and stably handle a large amount of materials, and the timely backflow of the empty tray is crucial to ensure the continuity and smoothness of production. The empty tray needs to be accurately and orderly returned to the starting point or other specified position from a specific position so as to be reused, forming a closed circulation system in the whole feeding detection process, thereby improving the production efficiency and equipment utilization.

[0003] The existing empty tray backflow mechanism has many problems in actual use: after conveying the empty tray to the required position, the corresponding clamping assembly needs to work cooperatively to complete the clamping operation of the empty tray. However, when the number of conveyed empty trays is large, a large number of empty trays will accumulate in the clamping area of the clamping assembly, which will seriously affect the clamping effect of the clamping assembly.

[0004] From the perspective of clamping accuracy, the accumulation of too many empty trays makes it difficult for the clamping assembly to accurately position a single empty tray. In this chaotic state, the empty trays are intertwined and pressed with each other, which makes it difficult for the clamping jaw to accurately align the target empty tray when clamping, and the clamping jaw is prone to clamping deviation, or even may not clamp the empty tray at all, which seriously damages the accuracy of the backflow process.

[0018] Working principle:

[0019] The empty tray body 131 is put into the rear end of the top of the flat belt 136, the servo motor 137 is started to drive the roller shaft body 134 to rotate, and the driving force of the flat belt 136 is provided. Two groups of flat belts 136 are in contact with the two sides of the bottom of the empty tray body 131, the flat belt 136 drives the empty tray body 131 to move, the moving direction is shown by the arrow in the figure, two groups of flat belts 136 are connected with the roller shaft body 134 through the driven shaft 128, and are driven by a servo motor 1371. Not only can the flat belt 136 move in the same direction, but also can reduce the cost;

[0020] Taking the rear end of the flat belt 136 as an example, the first group of photoelectric sensors 135 is marked as detection area a, the second group of photoelectric sensors 135 is marked as detection area b, and the third group of photoelectric sensors 135 is marked as detection area c. The second group of photoelectric sensors 135 is electrically connected with the three-axis cylinder 129, and when the second group of photoelectric sensors 135 detects the empty tray body 131, the three-axis cylinder 129 is controlled to push the blocking material plate 130 to move up. When the second group of photoelectric sensors 135 does not detect the empty tray body 131, the three-axis cylinder 129 is controlled to drive the blocking material plate 130 to move down. The third group of photoelectric sensors 135 is electrically connected with the blocking disc cylinder 132, and when the third group of photoelectric sensors 135 detects the empty tray body 131, the blocking disc cylinder 132 is controlled to drive the rod body to rise. When the third group of photoelectric sensors 135 does not detect the empty tray body 131, the blocking disc cylinder 132 is controlled to drive the rod body to descend. It should be noted that the third group of photoelectric sensors 135 cooperates with the clamping assembly on the detection equipment. When the photoelectric sensor 135 detects the empty tray body 131, it not only cooperates with the blocking disc cylinder 132 to block the subsequent moving empty tray body 131, but also stops the servo motor 1371 from driving the flat belt 136 to transport the empty tray body 131, and can also make the clamping assembly start the clamping work;

[0021] The empty tray body 131 is moved from the rear end of the flat belt 136 to the front end, first enters the detection area of the first group of photoelectric sensors 135, the photoelectric sensor 135 detects the conveying of the empty tray body 131, when the empty tray body 131 enters the detection area of the second group of photoelectric sensors 135, the second group of photoelectric sensors 135 cooperate with the three-axis cylinder 129, start the three-axis cylinder 129, the three-axis cylinder 129 pushes up the material blocking plate 130, and the material blocking plate 130 blocks the moving empty tray body 131, when the front end of the empty tray body 131 is in contact with the material blocking plate 130, at this time, the empty tray body 131 moves into the detection area of the third group of photoelectric sensors 135, the third group of photoelectric sensors 135 cooperate with the blocking disc cylinder 132, start the blocking disc cylinder 132, the blocking disc cylinder 132 extends the rod body upwards to block the next moving empty tray body 131, at this time, the detection equipment uses the clamping assembly to clamp the empty tray body 131 blocked by the material blocking plate 130, the empty tray body 131 moves away from the detection area of the third group of photoelectric sensors 135, the third group of photoelectric sensors 135 cooperate with the blocking disc cylinder 132, start the blocking disc cylinder 132 to drive the blocking rod body to move downwards, so that the subsequent empty tray body 131 moves into the detection area of the second and third groups of photoelectric sensors 135, and the above operation is repeated, so that the empty tray body 131 can be moved into the clamping area one by one for clamping, and the problem of mutual extrusion of the empty tray bodies 131 to affect the clamping efficiency is prevented.
