[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the intelligent positioning system adopted by the present invention, the longer the blowing plate is, the more the number of revolutions of the motor is, so that the distance that the limit rod moves to the left is greater, the larger the data A is, and the smaller the data B is, so as to ensure the center of gravity of the blowing plate, and avoid the blowing plate from falling due to the unstable center of gravity when the flip plate flips the blowing plate, thereby playing a preliminary positioning role, and at the same time, the number of revolutions of the motor is adjusted twice according to the rotation speed of the flip plate, so as to avoid the B part from falling due to the large resistance, and further protect the blowing plate, the faster the flip speed is, the larger the data of the A part is, and the blowing plate is less likely to fall, when the data of C and the data of D are both small, it is easily affected by the rotation speed of the flip plate, and thus the resistance is large, and the data A is further increased, and the number of revolutions of the motor is adjusted with high precision by adjusting the length and thickness of the blowing plate and the flip speed of the flip plate, so as to fully avoid the phenomenon of the blowing plate falling from the flip plate, and the positioning accuracy is greatly improved;

[0015] When the thickness of the blowing plate is greater than the system setting value, the resistance of part B is affected by its own weight and it is not easy to fall, so the rotation speed of the flip plate has little effect on the falling of the blowing plate, so that the number of rotations of the motor can be slightly reduced, which can relatively reduce the energy consumption of the motor, reduce production costs, and ensure the transportation stability of the blowing plate.

[0023] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The present invention provides a technical solution: a positioning device for hot rolling of a blown plate production, comprising a hot rolling transmission device for the blown plate production, a positioning mechanism, a flipping mechanism and an intelligent positioning system, wherein the hot rolling transmission device for the blown plate production comprises a transmission frame 1, the flipping mechanism comprises a flipping cavity 2, two support plates 21 and a flipping plate 22, the positioning mechanism comprises two slide rails 3, a limit rod 31, a tooth plate 32, a positioning cavity 33, a motor 331 and a gear 332, and a camera is installed above the transmission frame 1;

[0025] The flip chamber 2 is fixedly installed below the conveying frame 1, and the conveying frame 1 is used to transport the blown plate. A driving mechanism is arranged inside the flip chamber 2, and the driving mechanism is connected to the bottom of the flip plate 22. The two support plates 21 are fixedly installed above the flip chamber 2 and are arranged opposite to each other. The flip plate 22 bearing is installed between the two support plates 21. The two slide rails 3 are respectively fixedly installed on the front and rear sides of the flip plate 22. The limit rod 31 is slidably connected above the two slide rails 3 and is located on the upper surface of the flip plate 22. The tooth plate 32 is fixedly installed on the rear end of the limit rod 31. The positioning chamber 33 is fixedly installed on the side of the flip plate 22, and a notch 333 is opened on the top. The motor 331 is fixedly installed on the inner wall of the positioning chamber 33. The gear 332 is fixedly connected to the output end of the motor 331, and is located in the notch 333, and meshes with the tooth plate 32.

[0026] The intelligent positioning system is electrically connected to the driving mechanism, the motor 331 and the camera respectively;

[0027] The blowing plate is placed on the conveying rack 1 and transported by the conveying rack 1. The camera shoots the blowing plate, and then the blowing plate moves to the left side of the conveying rack 1 and is transported to the flip plate 22 until the left end of the blowing plate contacts the limit rod 31 and is blocked by the limit rod 31, thereby positioning. During the positioning process, the motor 331 runs, driving the gear 332 to rotate, and the gear 332 drives the tooth plate 32 to move through the engagement, and the tooth plate 32 drives the limit rod 31 to move through the slide rail 3. The position of the limit rod 31 is adjusted, and the positioning can be adjusted according to the shape and size of the blowing plate to prevent the blowing plate from falling due to instability after falling on the flip plate 22, thereby protecting the blowing plate and improving production efficiency.

[0028] The intelligent positioning system includes a data judgment module, a data conversion module and an intelligent control module. The data conversion module is electrically connected to the data judgment module and the intelligent control module respectively. The intelligent control module is electrically connected to the motor 331. The data judgment module is used to judge various parameters of the plate through a camera. The data conversion module is used to perform data conversion according to various parameters of the plate. The intelligent control module is used to control the number of rotations of the motor 331 according to the conversion result.

[0029] The data judgment module includes a plate length unit, a flipping speed unit and a plate thickness unit. The plate length unit is used to identify the length of the plate through a camera, the flipping speed unit is used to identify the flipping speed of the flip plate 22, and the plate thickness unit is used to identify the thickness of the plate through a camera.

[0030] The operation steps of the intelligent positioning system include:

[0031] Step S1, the camera identifies the length and thickness of the blown plate through the plate length unit and the plate thickness unit, and then the blown plate is transported to the flip plate 22 through the conveying rack 1;

[0032] Step S2, adjusting the first rotation number of the motor 331 according to the length of the blowing plate, then identifying the flipping speed of the flip plate 22 through the flipping speed unit, and then adjusting the second rotation number of the motor 331 according to the flipping speed of the flip plate 22;

[0033] Step S3, adjusting the third rotation number of the motor 331 according to the thickness of the blowing plate, and when the thickness of the blowing plate is greater than the system setting value, entering step S4, otherwise entering step S5;

[0034] Step S4, adjusting the number of rotations of the motor 331 to obtain a fourth number of rotations;

[0035] Step S5: After the limiting rod 31 reaches the position, the inflation plate is limited, and then the driving mechanism controls the flip plate 22 to flip.

[0036] In step S1 and step S2, the first rotation number is measured:

[0037] Q1 is the first rotation number of the motor 331, Q max is the maximum number of revolutions of the motor 331, L is the thickness of the blowing plate, and L max Maximum thickness;

[0038] Control the position of the limit rod 31 to limit the blowing plate. The length of the blowing plate part on the flip plate 22 is A, and the other part is B. The ratio of the turning plate 22 is adjusted to adjust the center of gravity of the turning plate 22;

[0039] The longer the blowing plate is, the more revolutions the motor 331 makes, so that the limit rod 31 moves a greater distance to the left, the larger the data A is, and the smaller the data B is, thereby ensuring the center of gravity of the blowing plate and preventing the blowing plate from falling due to unstable center of gravity when the flip plate 22 flips the blowing plate, thereby playing a preliminary positioning role.

[0040] In step S2, the second rotation number is measured:

[0041] V is the rotation speed of the flip plate 22, V max is the fastest rotation speed of the flip plate 22, Q2 is the second rotation number of the motor 331;

[0042] When the flip plate 22 flips, the portion B of the flip plate 22 is subjected to resistance, thereby performing a secondary adjustment on the number of rotations of the motor 331;

[0043] The number of rotations of the motor 331 is adjusted twice according to the rotation speed of the flip plate 22, which can prevent the B part from falling due to the large resistance, and further protect the inflation plate. The faster the flip speed, the faster the A

[0044] The larger the partial data, the less likely the blown plate will fall off.

[0045] In step S3, the third number of rotations is measured:

[0046] H is the thickness of the blown sheet, V max is the maximum thickness of the blown plate, Q3 is the third number of rotations of the motor 331;

[0047] Further control the position of the limit rod 31 to adjust the limit of the blowing plate. The weight of the blowing plate part on the flip plate 22 is C, and the other part is D. ratio, thereby further adjusting the center of gravity of the flip plate 22;

[0048] When the data of C and D are both small, they are easily affected by the rotation speed of the flip plate 22, and thus the resistance is large. The data A is further increased, and the number of rotations of the motor 331 is adjusted with high precision through the length and thickness of the blowing plate and the flip speed of the flip plate 22, which can fully prevent the blowing plate from falling from the flip plate 22 and greatly improve the positioning accuracy.

[0049] In step S3 and step S4:

[0050] When H>H 系 When H 系 The thickness of the blown plate set for the system: Q4 is the fourth rotation number of the motor 331;

[0051] When H≤H 系 When: Q4 = Q3;

[0052] When the thickness of the blowing plate is greater than the system setting value, the resistance encountered by part B is affected by its own weight and is not easy to fall off, so that the rotation speed of the flip plate 22 has little effect on the falling of the blowing plate, thereby slightly reducing the number of rotations of the motor 331, which can relatively reduce the energy consumption of the motor 331, reduce production costs, and ensure the transportation stability of the blowing plate.
