[0028] An automatic stacking device for a convenient food production line comprises a base 100, a vertical first electric cylinder 110 is arranged around the top of the base 100, a mounting platform 120 is arranged on the top of the output ends of the plurality of the first electric cylinders 110, a rotating plate 130 is rotatably arranged on the mounting platform 120, a vertical rotating column 140 is rotatably arranged at the center of the bottom wall of the inner cavity of the mounting platform 120 through a bearing seat, the upper end of the rotating column 140 rotates through the top wall of the mounting platform 120 and is fixed at the center of the bottom wall of the rotating plate 130, a worm gear 150 is arranged on the outside of the shaft of the rotating column 140, a fixing plate 160 is symmetrically arranged at the bottom of the inner cavity of the mounting platform 120, and a worm 170 meshing with the worm gear 150 is rotatably arranged between the two fixing plates 160; the height of the mounting frame 300 can be further adjusted by the first electric cylinder 110, so as to facilitate the clamping of food cans on the conveyor belt 400 of different heights;

[0029] The rotating plate 130 is provided with a mechanical arm assembly 200, and the mechanical arm assembly 200 includes a first arm 210 arranged on the top of the rotating plate 130, the front end of the first arm 210 is rotatably connected with a second arm 220, the other end of the second arm 220 is rotatably connected with a third arm 230, the other end of the third arm 230 is provided with a second electric cylinder 240 parallel thereto, and the output end of the second electric cylinder 240 is rotatably connected with a connecting seat 250;

[0030] A mounting frame 300 is provided at the bottom of the connecting seat 250, and the side cross-section of the mounting frame 300 is "n"-shaped. A transverse double-headed screw 310 is rotatably provided between the inner side walls of the mounting frame 300, and a guide rod 340 parallel to the double-headed screw 310 is fixedly provided. The threads on the left and right rod bodies of the double-headed screw 310 have opposite directions and are respectively screwed and penetrated with grab plates 320. The rod body of the guide rod 340 slides through the side walls of the two grab plates 320, and the two grab plates 320 are provided with an anti-slip layer 330 facing one side.

[0031] Furthermore, the lead angle of the worm 170 is smaller than the equivalent friction angle between the teeth of the meshing worm wheel 150, so that the worm 170 and the worm wheel 150 have self-locking properties and can achieve reverse self-locking, that is, only the worm 170 can drive the worm wheel 150, but the worm wheel 150 cannot drive the worm 170, thereby making the robotic arm assembly 200 more stable after the angle is adjusted.

[0032] Furthermore, support wheels 190 are arranged at equal intervals around the bottom of the rotating plate 130 with the rotating column 140 as the center, and the bottom of the support wheel 190 rolls on the top of the mounting platform 120. The support wheel 190 reduces the friction between the rotating plate 130 and the top of the mounting platform 120 when the rotating plate 130 rotates.

[0033] Furthermore, a first servo motor 180 is provided in the inner cavity of the base 100, and the output shaft of the first servo motor 180 rotates through the side wall of the fixed plate 160 and is connected to one end of the worm 170. After the worm 170 is driven to rotate by the first servo motor 180, the rotating column 140 is driven to rotate through the worm gear 150, thereby adjusting the direction of the robotic arm assembly 200.

[0034] Furthermore, a third electric cylinder 260 is provided between the top wall of the first arm 210 and the top wall of the second arm 220. The two ends of the third electric cylinder 260 are rotatably connected to the top wall of the first arm 210 and the top wall of the second arm 220 respectively. When the third electric cylinder 260 starts to extend and retract, the angle of the first arm 210 and the second arm 220 can be adjusted.

[0035] A fourth electric cylinder 270 is disposed between the bottom wall of the second arm 220 and the bottom wall of the third arm 230. Both ends of the fourth electric cylinder 270 are rotatably connected to the bottom wall of the second arm 220 and the bottom wall of the third arm 230, respectively. When the fourth electric cylinder 270 starts to extend and retract, the angles of the second arm 220 and the third arm 230 can be adjusted.

[0036] A fifth electric cylinder 280 is arranged between the outer side of the rod body of the output rod of the second electric cylinder 240 and the side wall of the connecting seat 250. The two ends of the fifth electric cylinder 280 are rotatably connected to the outer side of the rod body of the output rod of the second electric cylinder 240 and the side wall of the connecting seat 250 respectively. When the second electric cylinder 240 is started, the extension length of the mounting frame 300 can be controlled. When the fifth electric cylinder 280 starts to retract, the angle of the third arm 230 and the mounting frame 300 can be adjusted.

[0037] Furthermore, a second servo motor 350 is provided on the outer wall of the mounting frame 300, and the output shaft of the second servo motor 350 rotates through the side wall of the mounting frame 300 and is connected to one end of the double-headed screw rod 310. After the second servo motor 350 is started to drive the double-headed screw rod 310 to rotate, the two grabbing plates 320 gradually approach each other, thereby clamping convenience foods such as long cans.

[0038] During specific use, when it is necessary to adjust the orientation of the robot arm assembly 200, the first servo motor 180 is started to drive the worm 170 to rotate, and then the worm wheel 150 drives the rotating column 140 to rotate, so that the orientation of the robot arm assembly 200 can be adjusted. In addition, since the worm wheel 150 and the worm 170 also have self-locking properties, the robot arm assembly 200 is more stable after the orientation is adjusted, so that the food cans can be placed in the transport box 500 under different circumstances, thereby improving the flexibility of the robot arm assembly 200 and meeting the different needs of different users.

[0039] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
