[0032] Refer to Figure 1 and Figure 2 , a fixed plate 11 is fixed at the bottom of the workbench plate 1. The two conveyor belts 2 are arranged at intervals and horizontally on the workbench plate 1. The driving wheels of the two conveyor belts 2 are driven by a conveyor motor to rotate synchronously, thereby driving the two conveyor belts 2 to act synchronously. An upper plate 12 is arranged at intervals above the workbench plate 1. The four corners of the upper plate 12 are respectively fixedly connected to the workbench plate 1 through fixed columns. The upper plate 12 is located above the two conveyor belts 2.

[0033] Refer to Figure 1 and Figure 3, the lifting mechanism 3 includes a lifting drive source and a lifting seat 31. The lifting drive source is preferably a lifting electric cylinder 33. The lifting electric cylinder 33 is located below the workbench plate 1 and fixed to the bottom of the fixed plate 11. The lifting seat 31 is square and located on the output shaft of the lifting electric cylinder 33. A plurality of lifting guide columns 32 are fixed to the bottom of the lifting seat 31. All the lifting guide columns 32 pass through the fixed plate 11 movably. The lifting electric cylinder 33 drives the lifting seat 31 to move vertically up and down between the two conveyor belts 2, so as to lift the vacuum-packed products 9 placed on the two conveyor belts 2 from the two conveyor belts 2.

[0034] Referring to Figure 1 , Figure 2 and Figure 4 , the pressing and folding-down mechanism 4 includes a lower pressing plate 43, four folding-down plates 431, a pressing plate 44 and a pressing and folding-down drive source. The lower pressing plate 43 is square and is vertically movably arranged directly below the top plate 12. The four folding-down plates 431 are respectively fixed to the four edges of the lower pressing plate 43 (i.e., the edges in the length direction and the width direction). A plurality of lifting guide rods 42 are fixed to the top of the lower pressing plate 43. All the lifting guide rods 42 pass through the top plate 12 movably and extend outside the top plate 12, so that the lower pressing plate 43 can be positioned and connected to the top plate 12 through all the lifting guide rods 42. The pressing plate 44 is square and is arranged at an interval directly below the lower pressing plate 43. A plurality of pressing guide columns 46 are fixed to the top of the pressing plate 44.

The pressing and folding-down electric cylinder 41 drives the lower pressing plate 43, the four folding-down plates 431 and the pressing plate 44 to move up and down together, press down the vacuum-packed product 9, and fold down the aluminum foil edge of the vacuum-packed product 9.

[0035] Referring to Figure 1 , Figure 2 , Figure 5 and Figure 6, the two pairs of corner rolling and folding mechanisms are specifically a pair of first corner rolling and folding mechanisms 5 and a pair of second corner rolling and folding mechanisms 6. Among them, the pair of first corner rolling and folding mechanisms 5 and the pair of second corner rolling and folding mechanisms 6 are respectively arranged on two opposite sides of the conveyor belt 2, that is: the first corner rolling and folding mechanisms 5 are arranged at intervals on the left sides of the two conveyor belts 2, and the second corner rolling and folding mechanisms 6 are arranged at intervals on the right sides of the two conveyor belts 2. The lifting mechanism 3 and the pressing and downward folding mechanism 4 are both located between the pair of first corner rolling and folding mechanisms 5, and the lifting mechanism 3 and the pressing and downward folding mechanism 4 are both located between the pair of second corner rolling and folding mechanisms 6. In the present utility model, the structures of the pair of first corner rolling and folding mechanisms 5 and the pair of second corner rolling and folding mechanisms 6 are basically the same. Specifically, the pair of first corner rolling and folding mechanisms 5 are symmetrically arranged. Each first corner rolling and folding mechanism 5 includes a first corner roller 51, a first longitudinal movement driving source and a first transverse movement driving source. The first longitudinal movement driving source is specifically a first longitudinal movement cylinder 52, and the first transverse movement driving source is specifically a first transverse movement cylinder 53.

The first transverse movement cylinder 53 is vertically fixed on the first longitudinal movement cylinder 52 through an L-shaped first connecting plate 54. The first corner roller 51 is vertically and rotatably arranged on the output end of the first transverse movement cylinder 53. Since the pair of first corner rolling and folding mechanisms 5 are symmetrically arranged, the two first corner rollers 51 are symmetrically and reversely arranged to fold the two corners on the left side of the vacuum-packed product 9; the pair of second corner rolling and folding mechanisms 6 are symmetrically arranged. Each second corner rolling and folding mechanism 6 includes a second corner roller 61, a second longitudinal movement driving source and a second transverse movement driving source. The second longitudinal movement driving source is specifically a second longitudinal movement cylinder 62, and the second transverse movement driving source is specifically a second transverse movement cylinder 63.

The second transverse movement cylinder 63 is vertically fixed on the second longitudinal movement cylinder 62 through an L-shaped second connecting plate 64. The first corner roller 51 is vertically and rotatably arranged on the output end of the second transverse movement cylinder 63. Since the pair of second corner rolling and folding mechanisms 6 are symmetrically arranged, the two second corner rollers 61 are symmetrically and reversely arranged to fold the two corners on the right side of the vacuum-packed product 9.

[0036] Refer to Figure 1 , Figure 2 and Figure 5 , in order to fold the inwardly folded corners at the upper part of the vacuum-packed product 9, inner folding mechanisms 7 are respectively provided on the pair of first corner rolling and folding mechanisms 5 on the left side. Each inner folding mechanism 7 includes an inner folding roller 72 and an inner folding driving source. In the present utility model, the inner folding driving source is preferably an inner folding cylinder 71. The inner folding cylinder 71 is vertically fixed on the corresponding first longitudinal movement cylinder 52 through a Z-shaped plate. The inner folding roller 72 is arranged longitudinally on the workbench 1 at the output end of the inner folding cylinder 71. The inner folding roller 72 is located below the corresponding first corner roller 51 and is vertically arranged with the corresponding first corner roller 51.

[0037] Referring to Figure 7 and Figure 8 , the high-efficiency automatic folding device of the present utility model is mainly used for folding the aluminum foil edge of the vacuum packaging product 9. The vacuum packaging product 9 includes at least one encapsulation member 94 and an aluminum foil bag 8. The number of encapsulation members 94 can be one or multiple stacked together. Placing one or multiple stacked encapsulation members 94 in the same aluminum foil bag 8 and evacuating the air can form one said vacuum packaging product 9. In the present utility model, each encapsulation member 94 includes an upper tray 93, a chip 92, and a lower tray 91. In the same encapsulation member 94, the upper tray 93 covers the top of the lower tray 91 to form a cavity, and the chip 92 is located in the cavity, with the chip 92 clamped between the upper tray 93 and the lower tray 91.

[0038] Referring to Figures 1 to 11 , the working principle of the high-efficiency automatic folding device of the present utility model is as follows:

[0039] Place the vacuum packaging product 9 to be folded (as shown in Figure 7 and Figure 8 ) on two conveyor belts 2;

[0040] When the two conveyor belts 2 transport the vacuum packaging product 9 to be folded to directly above the lifting seat 31, the lifting electric cylinder 33 controls the lifting seat 31 to move upward, lifting the clamped vacuum packaging product 9 upward so that the vacuum packaging product 9 is separated from the two conveyor belts 2;

[0041] The pressing-down folding electric cylinder 41 controls the lower pressing plate 43 to move downward. The pressing plate 44 and the four lower folding plates 431 move downward together with the lower pressing plate 43 by a certain distance until the pressing plate 44 elastically presses the top of the vacuum packaging product 9. At this time, the four lower folding plates 431 press down the aluminum foil edge of the vacuum packaging product 9 to fold the aluminum foil edge of the vacuum packaging product 9 downward (as shown in Figure 9 );

[0042] The first transverse translation cylinder 53 controls the first corner roller 51 to move horizontally closer to the vacuum packaging product 9. The first longitudinal translation cylinder 52 drives the first transverse translation cylinder 53, the first corner roller 51, the inner folding cylinder 71, and the inner folding roller 72 to move inward along the longitudinal direction of the vacuum packaging product 9 together, so that the first corner roller 51 rolls and folds the corner of the vacuum packaging product 9 inward along the left corner folding line 81; at the same time, the first transverse translation cylinder 53 controls the second corner roller 61 to move horizontally closer to the vacuum packaging product 9. The second longitudinal translation cylinder 62 drives the second transverse translation cylinder 63 and the second corner roller 61 to move inward along the longitudinal direction of the vacuum packaging product 9 together, so that the second corner roller 61 rolls and folds the corner of the vacuum packaging product 9 inward along the right corner folding line 81 (as shown in Figure 10 );

[0043] The two inner folding cylinders 71 on the left control the lateral movement of the inner folding rollers 72, so that the folded part at the left corner of the vacuum-packed product 9 rolls along the inner folding line 82 towards the bottom of the vacuum-packed product 9 (as Figure 11 shown);

[0044] After the folding is completed, the pressing and lower folding mechanism 4 and the lifting mechanism 3 are reset in sequence, so that the folded vacuum-packed product 9 is placed on the two conveyor belts 2 again.

[0045] The high-efficiency automatic folding device of the present utility model adopts the design of double conveyor belts 2 to ensure the accurate positioning and stable forward movement of the vacuum-packed product 9 during the transmission process, laying a solid foundation for the subsequent folding operation. The whole device integrates the lifting mechanism 3 and the pressing and lower folding mechanism 4, and realizes the automatic downward folding of the aluminum foil edge of the vacuum-packed product 9 through precise control. The lifting mechanism 3 smoothly lifts the vacuum-packed product 9 from the conveyor belt 2 to create space for the lower folding operation; the pressing and lower folding mechanism 4 applies precise pressure to ensure that the folded part at the aluminum foil edge of the vacuum-packed product 9 is neat and firm. At the same time, two pairs of corner rolling and folding mechanisms are equipped to realize the rapid and accurate folding of the corners of the vacuum-packed product 9 through precisely controlled rotational movements. The mechanism is ingeniously designed and easy to operate, effectively improving the folding efficiency and the quality of the finished product.

[0046] The high-efficiency automatic folding device of the present utility model is mainly used to solve the problem of irregular folding patterns during the vacuum sealing process of semiconductor Dry Pack and improve the bag folding efficiency.

[0047] The above-disclosed are only the preferred embodiments of the present utility model, and the scope of the patent protection of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
