[0020] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] Example 1: A fully automatic material testing and labeling integrated machine, such as Figures 1-7 As shown, it includes a conveying unit 1 and an integrated operation unit 2 located above the conveying unit 1. The integrated operation unit 2 includes a gantry frame 3, a labeling mechanism 6, a film coating mechanism 7, and a testing mechanism 8. The bottom of the gantry frame 3 is connected to a "U"-shaped rotating frame 5 via an electric turntable 4. The labeling mechanism 6 and the film coating mechanism 7 are respectively located on the inner side walls of both ends of the "U"-shaped rotating frame 5. The testing mechanism 8 is located on the lower surface above the middle part of the "U"-shaped rotating frame 5.

[0023] The film covering mechanism 7 comprises a film releasing assembly and a film clamping and cutting assembly 16. The film releasing assembly comprises a longitudinal moving frame 14 and a film roll 15. The longitudinal moving frame 14 is longitudinally slidably connected to one side of the U-shaped rotating frame 5. The film roll 15 is rotationally connected to the inner side wall of the longitudinal moving frame 14 with rotation damping. The other side inner wall of the longitudinal moving frame 14 is rotationally connected with a transition shaft 17.

[0024] The labeling mechanism 6 comprises a horizontal moving plate 27, a winding roller 29, a transition roller 30 and a releasing roller 31 arranged in a right triangle shape and rotationally connected to the horizontal moving plate 27. The horizontal moving plate 27 is slidably connected to the U-shaped rotating frame 5 through a guide rod 32. One side outer wall of the horizontal moving plate 27 is fixed with a motor 28 through a bolt. The output shaft of the motor 28 is fixed to the end of the winding roller 29.

[0025] The film clamping and cutting assembly 16 comprises a mounting base 26 and two sets of opposite cutting knives 21, clamping plates 22 and rotating frames 23. The rotating frames 23 are rotationally connected to one side of the mounting base 26 through connecting shafts 25. Two sets of clamping plates 22 and cutting knives 21 are respectively fixed to the side walls of the two sets of rotating frames 23. The two connecting shafts 25 are drivingly matched through a gear set 24.

[0026] In use, first, the tray is placed at one end of the conveying part 1 for stacking. After the stacking is completed, the conveying part 1 conveys the product stack on the tray, Film winding process: during the conveying, the two rotating frames 23 are in a state of approaching each other. The free end of the film on the film roll 15 after the transition shaft 17 is clamped by the two clamping plates 22. Until the product stack is conveyed to below the comprehensive operation part 2, the longitudinal moving frame 14 slightly rises, so that the whole longitudinal moving frame 14 does not overlap with the film clamping and cutting assembly 16 in the height direction. Then the electric rotating disc 4 drives the U-shaped rotating frame 5 to rotate. The film is wound on the outside of the product stack to wrap, limit and pack. During this process, the longitudinal moving frame 14 gradually rises. When the U-shaped rotating frame 5 rotates 1-2 rounds, the two rotating frames 23 reversely rotate to loosen the end of the film and are in a low level state. Until the longitudinal moving frame 14 rises to the maximum height, reversely moves downward until reaching the minimum height. At this time, the two rotating frames 23 approach each other. The film between the product stack and the transition shaft 17 is clamped and fixed by the clamping plates 22. At the same time, the film between the clamping plates 22 and the product stack is cut by the cutting knives 21, realizing the film winding process.

[0027] Secondary labeling process: when the motor two 28 rotates, it will pull the base layer of the label, so that the label moves along the path of the unwinding roller 31, the transition roller 30, the winding roller 29, but because the label has a large corner when passing through the transition roller 30, and the label layer and the base layer are fixed by the adhesive, and the label layer has a certain strength, it has the tendency to remain unchanged, so that the label layer separates from the base layer at the corner, so that the side of the label layer with adhesive leaks out, and after leaking out about one third of the length of the entire label, the motor two 28 stops, and the state is maintained until the film is wound to the last turn, the cross slide plate 27 moves relative to the "U" shaped turret 5, so that the side of the label layer that leaks out contacts the film, and after contacting, the film is adhered to the outside of the film due to the action of the adhesive, and at the same time the motor two 28 starts, which transports the label at the same speed as the rotation speed of the "U" shaped turret 5, and the cross slide plate 27 also slides relative to the "U" shaped turret 5 to compensate for the change in the horizontal distance between the label layer and the product stack of the cube caused by the rotation of the "U" shaped turret 5, until the entire label is completely fed out and adhered to the outside of the film, completing the labeling process.

[0028] The device, by taking the rotation of the "U" shaped turret 5 as the basis of movement, sets the labeling mechanism 6 and the film covering mechanism 7 on both sides of the "U" shaped turret 5, and cooperates with the conveying of the conveying part 1, so that secondary packaging and secondary labeling can be automatically synchronized, and the integration is high, the cost is reduced, and the occupied area is relatively small.

[0029] In order to solve the driving problem; as Figures 1-6 As shown, the inner wall of the "U" shaped turret 5 is fixed with a motor one 12 through bolts, the inner wall of the "U" shaped turret 5 is rotatably connected with a lead screw 13, the outer wall of the lead screw 13 is connected with the inner wall of the longitudinal moving frame 14 through threads, and the output shaft of the motor one 12 is connected with the end of the lead screw 13 through a shaft coupling; when the motor one 12 starts, it can drive the lead screw 13 to rotate, so as to drive the longitudinal moving frame 14 to rise and fall through the threaded connection.

[0030] One side of the mounting seat 26 is fixed with a telescopic device two 18 through bolts, the telescopic end of the telescopic device two 18 is rotatably connected with a connecting rod one 19, the other end of the connecting rod one 19 is rotatably connected with a connecting rod two 20, and the other end of the connecting rod two 20 is fixed to the end of one of the connecting shafts 25; when the telescopic device two 18 telescopes, it can drive the connecting rod one 19 to move, so as to drive the connecting rod two 20 to rotate through the connecting rod one 19, and then drive the turret 23 to rotate through the connecting shaft 25.

[0031] One side of the "U" shaped turret 5 is fixed with a telescopic device two 33 through bolts, and the telescopic end of the telescopic device two 33 is fixed to the side wall of the cross slide plate 27 through bolts; when the telescopic device two 33 telescopes, it can drive the cross slide plate 27 to slide.

[0032] Because there may be one or more defects in the stacking, and the stack height may be over or insufficient, in order to solve the detection problem, as shown in Figure 3 The detection mechanism 8 includes a fixed seat 10 and a visual camera 11, the fixed seat 10 is fixed to the bottom outer wall of the "U" type rotating frame 5 by bolts, the visual camera 11 is fixed to the middle bottom outer wall of the fixed seat 10 by bolts, and a plurality of optical distance measuring heads 9 are fixed to the outer walls around the visual camera 11.

[0033] And when the whole comprehensive operation department 2 works, the visual camera 11 is located above the center of the product stack.

[0034] The detection principle of the detection mechanism 8 is: S1: calibrate the visual camera 11, acquire images at different positions from the visual camera 11 through a standard square plate or paper, and compare the size of the square profile collected by the visual camera 11 with the actual size of the standard square plate or paper to obtain the function relationship k=f(L) between the proportion k and the distance L between the standard square plate or paper and the visual camera 11; S2: acquire images by the visual camera 11 and extract features of the product edge profile, if the profile part is rectangular, it is determined that the previous packaging is abnormal, if the profile part is rectangular, the following steps are continued; S3: acquire the distance between the visual camera 11 and the upper surface of the product stack by the optical distance measuring head 9, take the average of a plurality of distances as the distance output value L1, then calculate the profile image area S1 through the extracted rectangular profile, and determine the cross-sectional area S2 of the product stack according to the set product stack size; S4: calculate whether the equation S1 / S2=k=f(L1) is established, if yes, it means that the product stack is normal, and the subsequent packaging and labeling are carried out, otherwise, it is determined to be abnormal, and the alarm processing is carried out.

[0035] The device can determine whether the product stack has local packaging box missing or product stack overheight, insufficient height stacking defects by using the distance measurement and image acquisition of the optical distance measuring head 9 and the visual camera 11, realizes the defect detection before packaging and labeling, and ensures the accuracy of the whole operation.

[0036] In use, first place the tray on one end of the conveying part 1 for stacking, after the stacking is completed, the conveying part 1 conveys the product stack on the tray, Detection process: Image acquisition is performed using vision camera 11, and feature extraction is performed on the product edge contour. If the contour is rectangular, the previous packaging is determined to be abnormal. If the area passed is rectangular, the following steps are continued. The distance between vision camera 11 and the upper surface of the product stack is obtained through optical rangefinder 9, and the average of multiple distances is taken as the distance output value L1. Then, the area S1 of the contour image is calculated through the extracted rectangular contour, and the cross-sectional area S2 of the product stack is determined according to the set product stack size. The equation S1 / S2=k=fL1 is calculated to see if it holds true. If it holds true, it means that the product stack is normal, and subsequent packaging and labeling are carried out. Otherwise, it is determined to be abnormal, and an alarm is triggered.

[0037] Film winding process: During the conveying process, the two rotating frames 23 are in a close-to-each-other state. The free end of the film on the film roll 15 after passing the transition shaft 17 is clamped by the two clamping plates 22. After the product stack is conveyed to the bottom of the integrated operation section 2, the longitudinal moving frame 14 will rise slightly so that the entire longitudinal moving frame 14 does not overlap with the clamping and cutting film assembly 16 in the height direction. Then the electric turntable 4 will drive the "U"-shaped rotating frame 5 to rotate. The film is wrapped around the outside of the product stack for packaging and positioning. During this process, the longitudinal moving frame 14 will gradually rise. After the "U"-shaped rotating frame 5 rotates 1-2 times, the two rotating frames 23 will rotate in opposite directions to loosen the film end and put it in a low horizontal state until the longitudinal moving frame 14 rises to the maximum height and then moves downward in the opposite direction until it reaches the minimum height. At this time, the two rotating frames 23 approach each other and use the clamping plates 22 to clamp and fix the film between the product stack and the transition shaft 17. At the same time, the cutter 21 cuts the film between the clamping plates 22 and the product stack, realizing the film winding process.

[0038] Secondary labeling process: When motor 28 rotates, it pulls the base layer of the label, causing the label to move along the path of unwinding roller 31, transition roller 30, and take-up roller 29. However, because the label has a large turning angle when passing through transition roller 30, and the label layer is fixed to the base layer with adhesive, and the label layer has a certain strength and tends to maintain its original shape, the label layer will separate from the base layer at the turning point, causing the adhesive side of the label layer to leak out. After about one-third of the entire label length has leaked out, motor 28 stops, ensuring the label layer remains in place. The label layer remains in a fixed position until the film is wound to its last turn. At this point, the transverse plate 27 moves relative to the "U"-shaped rotating frame 5, causing the exposed side of the label layer to come into contact with the film. After contact, the label adheres to the outside of the film due to the adhesive. Simultaneously, the motor 28 starts and transports the label at the same speed as the "U"-shaped rotating frame 5. At the same time, the transverse plate 27 slides relative to the "U"-shaped rotating frame 5 to compensate for the change in the lateral distance between the label layer and the cubic product stack caused by the rotation of the "U"-shaped rotating frame 5, until the entire label is completely delivered and adhered to the outside of the film, completing the labeling process.
