The existence of the two positioning sensors 410 can position the tray, provide positioning accuracy for the precise grabbing of the material taking and placing assembly 4, and improve the accuracy of grabbing.

[0059] In another new embodiment, as shown in Figure 8As shown, the tray assembly 2 comprises a motor base 21 arranged in the frame body 11, a circular bottom plate 22 arranged on the motor base 21, a plurality of circular feeding grooves 23 arranged on the periphery of the bottom plate 22, a top cover plate 24 arranged on the bottom plate 22, the top cover plate 24 being connected with the bottom plate 22 through a plurality of guide columns 25, and the edge of the top cover plate 24 is also provided with a discharging groove 26 matched with the feeding groove 23.

[0060] The motor base 21 is provided with a motor, the driving shaft of the motor is arranged at the bottom center of the bottom plate 22, and the motor drives the bottom plate 22 to rotate. In actual application, the staff continuously puts down the tray from the discharging groove 26, and the guide column 25 limits the tray to avoid skewing during production. When all the feeding grooves 23 and the discharging grooves 26 and the guide columns 25 on the bottom plate 22 are placed with the tray, the bottom plate 22 is driven to rotate by the motor, and when one group of trays is detected by the positioning sensor 410, the bottom plate 22 stops rotating. At this time, the feeding assembly 3 lifts the tray column as a whole, and the feeding and taking assembly 4 takes the tray one by one. When all the trays are taken, the feeding assembly 3 is lowered to the initial position, the bottom plate 22 rotates again until the next group of trays is detected, so as to realize the continuity of taking the tray.

Since the diameter of the discharging groove 26 is larger, it is convenient to place the tray. As shown in Figure 9 As shown, the bottom plate 12 of the equipment frame body 1 is provided with a square notch 110 matched with the feeding groove 23, the bottom plate 12 is provided below with a sensor 111 matched with the square notch 110, and the sensor 111 is located at the edge of the square notch 110; the sensor 111 can detect whether there is a tray at the current square notch 110, and the sensor 111 does not hinder the up and down movement of the lifting seat 34.

[0062] In another new embodiment, as shown in Figure 8As shown, the outer side of the feeding groove 23 and the discharging groove 26 is provided with a through groove 27, and the lifting seat 34 can pass through the through groove 27 because the lifting seat 34 is a vertically arranged plate, thereby facilitating the step-by-step lifting of the tray. The bottom of the bottom tray 22 is further provided with a sensor matched with the feeding groove 23, which can intelligently detect whether the tray exists at the feeding groove 23; and the sensor is symmetrically arranged with the through groove 27 about the center of the feeding groove 23, and the sensor does not hinder the up-and-down movement of the lifting seat.

[0063] In another new embodiment, as Figure 10 As shown, the clamping cylinder 48 comprises a cylinder body 481, a telescopic groove 482 arranged at the bottom end of the cylinder body 481, a pair of T-shaped mounting blocks 483 arranged inside the telescopic groove 482 and capable of moving along the telescopic groove, a clamping jaw column 484 arranged inside the T-shaped mounting block 483, and a semicircular limiting baffle 485 arranged on the clamping jaw column 484. The two clamping jaw columns arranged inside the T-shaped mounting blocks are symmetrically arranged and cooperated with each other, and the clamping jaw column 484 and the limiting baffle 485 move synchronously with the T-shaped mounting block 483. The clamping jaw column 484 comprises an upper semicircular column 4841 at the upper part, a middle semicircular column 4842 at the middle part, and a semicircular cone 4843 at the lower part. The bottom end of the upper semicircular column 4841 is at the same height as the bottom end of the T-shaped mounting block 483, the limiting baffle 485 is arranged at the bottom of the upper semicircular column 4841, and the limiting baffle 485 is arranged close to the outer side wall of the middle semicircular column 4842. In the application process, the clamping cylinder is lowered to the tray under the action of the lifting cylinder 47. At this time, because the two semicircular cones 4843 cooperatively form a complete conical structure, the bottom end of the clamping jaw column 484 can conveniently enter the central through hole of the tray, and because of the existence of the two limiting baffles 485, when the limiting baffles 485 are close to the tray, the tray can be prevented from being damaged when the lifting cylinder 47 further descends. When the clamping cylinder 48 is lowered to the appropriate position, the cylinder body 481 starts to ventilate, the two T-shaped mounting blocks 483 move away from each other along the telescopic groove 482, and drive the clamping jaw column 484 and the limiting baffle 485 to move. With the unfolding of the clamping jaw column 484, the central hole of the tray can be expanded outward, and then the lifting cylinder 47 is lifted, thereby completing the grabbing of the tray.
