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

[0022] For example, Figures 1 to 5The utility model provides a carton positioning centering machine, including transmission assembly 1 and support frame 2, the top fixedly connected with electric telescopic handle 3 of support frame 2, the inside movable connection of support frame 2 has square plate 4, both ends of square plate 4 bottom are fixedly connected with round bar 5, support frame 2 one side is fixedly connected with camera 6, the inside of support frame 2 is provided with sensor 7 and controller 8, the middle of transmission assembly 1 both sides all movable joint has the pivot 9, the surface of pivot 9 is provided with arc groove 10, and the outer parts of two pivot 9 are fixedly connected with first guide rod 11 and second guide rod 12 respectively, and the inside of first guide rod 11 and second guide rod 12 all is provided with a plurality of ball bearings 13, and the surface of transmission assembly 1 top places carton 14.

[0023] Adopt the above scheme: through square plate 4 drive two round bar 5 lower, to make the convex rod of round bar 5 bottom end along the track of arc groove 10 sliding, and because the orientation of two arc grooves 10 is opposite, therefore, two pivot 9 will rotate towards each other, through the radian of arc groove 10 is forty degrees, and then make two pivot 9 drive first guide rod 11 and second guide rod 12 rotate towards each other forty degrees, will make the triangular angle between the two, which is compatible with carton 14, then, carton 14 moves, and under the guidance of first guide rod 11 and second guide rod 12, and fit with the angle, and then reach the effect of centering positioning carton 14, and then improve the packaging efficiency.

[0024] Through the inside of first guide rod 11 and second guide rod 12 is provided with a plurality of ball bearings 13, its role is, in the process of carton 14 centering positioning, it will contact and relative motion with the side wall of first guide rod 11 or second guide rod 12, and by setting ball bearings 13, can make the friction mode between carton 14 and first guide rod 11 and second guide rod 12 change, from the original sliding friction to rolling friction, and the friction of rolling friction is far less than sliding friction, when carton 14 moves, make a plurality of ball bearings 13 respectively in the inner wall between first guide rod 11 and second guide rod 12 roll, will make the resistance that carton 14 receives greatly reduce.

[0025] As Figure 1 , Figure 3 and Figure 4 As shown in the drawings, the bottom end of the round bar 5 penetrates the outer wall of the support frame 2 and extends to the outside of the support frame 2, the bottom end of the round bar 5 is fixedly connected with a convex rod, the radian of the arc groove 10 is forty degrees, the orientation of the two arc grooves 10 is opposite, the convex rod at the bottom end of the round bar 5 is movably connected at the top of the arc groove 10 in the initial state, the round bar 5 moves downward to drive the convex rod to slide along the track of the arc groove 10, and the two pivot 9 rotate towards each other, the two sides of the support frame 2 are provided with square grooves.

[0026] Adopting the above scheme: square grooves are arranged on both sides of the support frame 2, which can reduce the contact or collision between one end of the first guide rod 11 or the second guide rod 12 and the side wall of the support frame 2 when the first guide rod 11 or the second guide rod 12 rotates, thereby improving the stability of the device operation.

[0027] As shown in Figure 1 , Figure 3 and Figure 5 , the first guide rod 11 and the second guide rod 12 rotate around the two rotating shafts 9 as the axes, the length of the second guide rod 12 is greater than that of the first guide rod 11, the bottom end of the electric telescopic rod 3 is fixedly connected with the square plate 4, the carton 14 is in the shape of an equilateral triangle, the included angle between the first guide rod 11 and the second guide rod 12 after abutting is triangular, the transmission assembly 1 is composed of two transmission wheels and a transmission belt, and one end of the transmission assembly 1 is fixedly connected with the motor 15.

[0028] Adopting the above scheme: the carton 14 is in the shape of an equilateral triangle, which can interact with the triangular included angle of the first guide rod 11 and the second guide rod 12 in the same way when the carton 14 enters the middle part of the first guide rod 11 and the second guide rod 12, so that the guiding force, friction and other physical factors acting on each corner and edge of the carton 14 are relatively uniform, thereby stably and accurately achieving centering.

[0029] The working principle and use process of the utility model are as follows: the carton 14 is placed on the transmission belt of the transmission assembly 1, then the position of the carton 14 is monitored by the camera 6, when the carton 14 is located directly below the camera 6, at this time, the camera 6 converts the detected information into an electric signal, and transmits the digital signal containing the position information of the carton 14 to the controller 8 through a communication interface such as USB and Ethernet, when the controller 8 receives the electric signal transmitted by the camera 6, the signal is analyzed, and a control signal is sent to the driving circuit of the electric telescopic rod 3 through the output port, and then the square plate 4 is driven downward by the electric telescopic rod 3, the two round rods 5 are synchronously moved while the square plate 4 moves downward, and then the convex rods at the bottom of the round rods 5 slide along the track of the arc grooves 10, and since the directions of the two arc grooves 10 are opposite, the two round rods 5 move downward while the two rotating shafts 9 are rotated forty degrees in opposite directions through the two arc grooves 10, thereby driving the two first guide rods 11 and the second guide rods 12 to rotate in opposite directions, when the two rotating shafts 9 rotate forty degrees, the first guide rod 11 and the second guide rod 12 abut each other, thereby forming a triangular included angle matched with the carton 14;

[0030] When the carton 14 moves on the transmission assembly 1, three edges of the carton 14 are in contact with the inner walls of the first guide rod 11 and the second guide rod 12 respectively, so that the interaction force is generated, and the three corners of the carton 14 are naturally inclined to be parallel or coincident with the side edges of the first guide rod 11 and the second guide rod 12, until one end of the carton 14 is coincident with the included angle of the first guide rod 11 and the second guide rod 12, and then the effect of centering and positioning the carton 14 is achieved. While the carton 14 moves on the transmission assembly 1, the sensor 7 also monitors the real-time position of the carton 14, and when the centering is completed, the sensor 7 converts the image information and position detected at this time into an electric signal and transmits it to the controller 8, so that the controller 8 receives the command and issues an instruction to the electric telescopic rod 3, and then drives the square plate 4 to move upwards through the electric telescopic rod 3, thereby driving the two round rods 5 to move upwards, and then through the cooperation of the round rods 5 and the arc grooves 10, the two rotating shafts 9 rotate in opposite directions and drive the first guide rod 11 and the second guide rod 12 to reset, so as to facilitate the continued movement of the centering and positioning ball 13 into the next link.
