Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0027] As Figure 1 shown, a preferred embodiment of the present application proposes an automatic steel sheet feeding device, which mainly comprises a machine table 5, a steel sheet feeding module 1, a conveying module 2, a jacking platform module 4, a tray turning module 3 and the like, wherein the steel sheet feeding module 1, the conveying module 2, the jacking platform module 4 and the tray turning module 3 are all installed on the machine table 5, the tray turning module 3 is located above the steel sheet feeding module 1, the conveying module 2 and the jacking platform module 4, and the jacking platform module 4 is located below the conveying module 2.

[0028] Specifically, referring to Figure 2 , the steel sheet feeding module 1 mainly comprises a bottom plate 11, a bin, a screw motor 12 and a top plate 13, wherein the bin is placed on the bottom plate 11, limiting blocks 18 are arranged at four corners of the bin on the bottom plate 11, and are used for limiting the bin. The screw motor 12 and the top plate 13 are each provided with two, which correspond to two groups of steel sheets 7 in the bin respectively. The screw motor 12 is installed at the bottom of the bottom plate 11, and the top plate 13 is located above the screw motor 12 and is connected with the screw rod of the screw motor 12.

[0029] The bottom plate 11 has an avoiding hole, so that the screw motor 12 drives the top plate 13 to move up and down, and the two groups of steel sheets 7 in the bin are jacked upward.

[0030] In order to make the top plate 13 move up and down stably, a guide rod is arranged at the bottom of the top plate 13, which is connected to the bottom plate 11 in a sliding manner through a shaft sleeve. A guide rod is also arranged at the bottom of the bottom plate 11, and the bottom of the screw rod of the screw motor 12 is rotatably connected to a connecting piece 17, and the other end of the connecting piece 17 is connected to the guide rod in a sliding manner, so as to ensure that the screw rod of the screw motor 12 moves up and down stably.

[0031] As shown in Figure 2 , two groups of stacked steel sheets 7 are stored in the hopper. The hopper is mainly composed of a hopper plate 14 and a plurality of limiting rods 15. There are eight limiting rods 15 in total, and each group of steel sheets 7 corresponds to two limiting rods 15 at both ends, which are used to limit the two sides of the steel sheets 7. Four positioning rods 16 are also arranged on the hopper plate 14, and each group of steel sheets 7 corresponds to one positioning rod 16 at both ends. Since the steel sheets 7 have holes, the positioning rods 16 can guide and position the steel sheets 7 by passing through the holes.

[0032] Each group of steel sheets 7 has a through hole below the hopper plate 14, so that the top plate 13 can pass through the through hole to lift the steel sheets 7 upward. By driving the top plate 13 to move upward by the screw motor 12, the steel sheets 7 are lifted layer by layer upward, so that the tray module 3 can grab the steel sheets 7. The two groups of steel sheets 7 in the hopper are symmetrically distributed, so the tray module 3 will grab two steel sheets 7 and then place them on the product 6.

[0033] As shown in Figure 3 , Figure 4 , the tray module 3 is mainly composed of a multi-axis moving module 31 and a suction assembly 32. The multi-axis moving module 31 has three linear axes and one rotary axis, which are used to control the movement and rotation of the suction assembly 32 to adjust its position.

Each fixed plate 322 is provided with three suction cups 323, and the suction cups 323 are connected to a negative pressure mechanism. The suction cups 323 generate negative pressure to suck the steel sheets 7.

[0034] As shown in Figure 5 , the conveying module 2 is composed of two conveying chains 21. The two ends of the conveying chains 21 are respectively connected to the width adjustment seats installed on the machine table 5 in a sliding manner. The width adjustment seats are rotated by the screw rod, driving the two conveying chains 21 to move, thereby adjusting the distance between the two conveying chains 21 to adapt to products 6 of different sizes. The conveying chains 21 adopt belt conveying, which drives the products 6 to move by rotating the belt.

[0035] A limiting plate 211 is arranged above each conveying chain 21, which is located directly above the lifting platform module 4 and cooperates with the lifting platform module 4.

[0036] AsFigure 6 As shown in the drawings, the jacking platform module 4 is mainly composed of a base 41, a platform plate 42, a jacking cylinder 43 and a blocking mechanism, wherein the bottom of the platform plate 42 is provided with a guide rod at each of the four corners, and the guide rod is connected to the base 41 through a shaft sleeve for up and down sliding connection to ensure the stable lifting of the platform plate 42. The jacking cylinder 43 is vertically fixed on the base 41, and the output end of the jacking cylinder 43 is connected to the middle part of the bottom of the platform plate 42 for driving the platform plate 42 to lift. The base 41 is connected to the conveying chain 21 through a connecting block 44 for fixing the jacking platform module 4. The base 41 is provided with a waist-shaped hole to adjust the installation position of the connecting block 44 according to the spacing of the two conveying chains 21.

[0037] The blocking mechanism is provided with two, which are located on both sides of the platform plate 42 and in the direction of the incoming material of the conveying module 2 to block the product 6. The blocking mechanism is composed of a blocking cylinder 45 and a blocking block 46, the blocking cylinder 45 is vertically arranged, and the blocking block 46 is connected to the output end of the blocking cylinder 45, and the blocking block 46 is driven by the blocking cylinder 45 to move upward to intercept the product 6 on the conveying module 2.

[0038] When the product 6 enters directly above the platform plate 42, the jacking cylinder 43 controls the platform plate 42 to move upward, and the platform plate 42 lifts the product 6 on the conveying module 2 upward to separate from the conveying chain 21, and the product 6 is clamped by the platform plate 42 and the limiting plate 211, then the placing module 3 places the two steel sheets 7 sucked by the placing module 3 to the corresponding positions on the product 6, and the connecting end 8 is pressed tightly by the presser foot of the steel sheet 7 to make the connecting end 8 tightly contact with the product.

[0039] The above technical scheme only embodies the preferred technical scheme of the present application, and some changes made by the person skilled in the art to some parts of the present application also embody the principle of the present application and are within the protection scope of the present application.
