[0034] The tray automatic feeding device provided by the utility model first places the tray stack carrying material by artificial or external mechanical hand on two limit blocks 24, when tray feeding operation starts, first Z axle cylinder 21 and second Z axle cylinder 22 reset contraction simultaneously, and all trays on limit block 24 are lowered to the moving frame 14 of conveying line 1, at this time, first Y axle cylinder 23 drives limit block 24 and separates from tray, second Z axle cylinder 22 drives limit block 24 to move the height of a tray, first Y axle cylinder 23 promotes limit block 24 and inserts between the bottom and the second last tray, first Z axle cylinder 21 drives limit block 24 to drive multiple trays on limit block 24 and separate from the tray of moving frame 14, finally, through the pneumatic lead screw 15 on conveying line 1, moving frame 14 drives the tray along conveying line 1 and is sent to target station to carry out the feeding operation of the material in tray, the tray automatic feeding device can automatically convey the tray carrying material to target station and carry out feeding operation, reduces manual operation and improves feeding efficiency.

[0035] Specifically, as Figures 1 to 3As shown, the conveying line 1 in the embodiment is composed of two opposite parallel arranged cross beams 10 and longitudinal beams 11 connected at both ends of the two cross beams 10; the inner side of the two cross beams 10 is respectively provided with two second sliding rails 12 parallel to each other, the second sliding rails 12 are both provided with second sliding blocks 13, and a moving frame 14 for moving the tray is connected between the two second sliding blocks 13, further, the moving frame 14 can also be provided with a matching bracket at the bottom of the tray as a carrier to make the tray more stable during transportation; the inner side of the cross beam 10 below one of the second sliding rails 12 is provided with a pneumatic lead screw 15, the driving end of the pneumatic lead screw 15 is connected to the moving frame 14 or the second sliding block 13, the moving frame 14 is driven by the pneumatic lead screw 15 to drive the tray to move on the conveying line 1, and the limiting mechanism 2 is installed on the side surface of the two cross beams 10 close to one end thereof.

[0036] As shown in the embodiment, Figure 3 although the pneumatic lead screw 15 can control the stroke of the moving frame 14 moving on the conveying line 1, in order to improve the tray to be more accurately lowered to the moving frame 14 and accurately conveyed to the designated station below the external feeding mechanism by the moving frame 14 for material handling, at least two limiting sensors 101 are arranged on the inner side of the cross beam 10 at intervals, and a limiting sensing sheet 131 matched with the limiting sensor 101 is installed on the sliding block, the stroke of the moving frame 14 is accurately controlled by the limiting sensing sheet 131 and the limiting sensor 101, so as to improve the accurate conveying of the tray and the material in the tray by the tray automatic feeding device.

[0037] Further, as shown in the embodiment, Figure 2When the trays loaded with materials are stacked on the limiting blocks 24 by artificial or external mechanical hands, it is possible that the displacement between the trays occurs, which causes the uneven placement between the trays and affects the placement of the trays on the moving frame 14 and causes unavoidable damage to the trays during the conveying. In order to avoid this risk, two longitudinal guide plates 16 are vertically installed on the upper end of the two beams 10 and close to the limiting mechanism 2. The body of the longitudinal guide plate 16 is in the shape of "L", and the top end thereof is outwardly inclined. Therefore, when the trays are placed on the limiting blocks 24, the two longitudinal guide plates 16 can be used as the base points for accurate placement. On the other hand, the transverse guide plates 17 are installed on the upper end of the two beams 10 along the X-axis direction of the beams 10. The end of the transverse guide plate 17 close to the longitudinal guide plate 16 is outwardly inclined. When the moving frame 14 drives the trays to move, the transverse guide plate 17 can prevent the displacement of the trays during the conveying process and ensure the stability of the conveying of the trays. Further, when the moving frame 14 is not installed with the bracket matched with the structure of the bottom of the tray or the tray and the moving frame 14 are in plane contact, the inertia will be generated at the moment when the pneumatic lead screw 15 is started. Therefore, the baffle plate is installed at the tail end of the moving frame 14, the free end of the baffle plate 141 extends upward, and the baffle plate 141 is used to prevent the displacement of the tray under the inertia, further improving the stability of the conveying of the tray.

The two first sliding blocks 203 are installed with the "U"-shaped movable plate 204. The first Z-axis cylinder 21 is vertically installed between the two first sliding rails 202 of the bottom plate 201. The top end of the "U"-shaped movable plate 204 is connected with the top plate 205 arranged in a horizontal shape. The top plate 205 and the inner corner of the "U"-shaped movable plate 204 are provided with the reinforcing rib 206 to improve the bearing capacity and stability of the top plate 205. The bottom of the second Z-axis cylinder 22 is installed at the extension end of the first Z-axis cylinder 21. The extension end of the second Z-axis cylinder 22 is connected to the bottom of the top plate 205. The first Y-axis cylinder 23 is installed on the top surface of the top plate 205, and the free end of the limiting block 24 thereof extends toward the tray.

The first Y-axis cylinder 23 is used to drive the limiting block 24 to reciprocate in the Y-axis direction. In this structure, the limiting mechanism 2 can stably and accurately place the tray on the limiting block 24 in order to be conveyed on the moving frame 14, and the feeding efficiency of the tray automatic feeding device is improved.

[0039] Further, as shown in Figure 1 and Figure 5As shown, one side of the limiting mechanism 2 is located on the side of the cross beam 10, and a tray separation assembly 3 is also installed on the side of the cross beam 10, the tray separation assembly 3 comprises a longitudinal connecting plate 30 vertically installed on the side of the cross beam 10, the bottom of the longitudinal connecting plate 30 is provided with an adjusting hole, and the longitudinal connecting plate 30 is movably adjusted and installed on the cross beam 10 through the adjusting hole, and the top of the longitudinal connecting plate 30 is provided with a second Y-axis cylinder 31, the telescopic end of the second Y-axis cylinder 31 is connected with a push block 32, the push block 32 is horizontally arranged, and the free end of the push block 32 is arranged in a "knife edge" shape and extends towards the tray direction; in actual operation, the material in the tray may be washed through the previous process, which may cause residual water stains on the tray, and when a plurality of trays are stacked together, the trays are difficult to separate due to the adsorption of water stains, therefore, under the above structure, the second Y-axis cylinder 31 pushes the push block 32 to separate the trays, thereby improving the efficiency and stability of the tray lowering to the moving frame 14.

[0040] Specifically, as shown in the drawings, Figure 1 As shown, at least two supporting columns 18 are respectively installed on the sides of the two cross beams 10, and the tray automatic feeding device is stably installed on the ground or other workbench for operation through the supporting columns 18, thereby improving the applicability of the tray automatic feeding device.
