DETAILED DESCRIPTION

[0018] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0019] refer to Figures 1 to 3

[0020] A labeling device with negative pressure label suction comprises a fixed plate 1, the lower side of which is elastically connected to an inverted frame plate 2, a flexible adsorption plate 3 is arranged outside the frame plate to cover the lower port of the frame plate so that the lower port area of ​​the frame plate forms an adsorption area, and a plurality of fans 4 are installed on the upper end surface of the frame plate for drawing air upward to form a negative pressure in the space surrounded by the frame plate and the flexible adsorption plate, so that the air is drawn outward by the fan to form a negative pressure in the space where the frame plate and the flexible adsorption plate cooperate, thereby making the flexible adsorption plate at the lower end of the frame plate have adsorption force so as to be used for adsorbing labels.

[0021] In this embodiment, in order to achieve elastic connection between the frame plate and the fixed plate and reduce the buffering force during labeling or label suction, linear bearings 5 ​​are fixed on all four sides of the fixed plate and guide columns 6 are installed. A limiting nut is fixed to the upper end of the guide column. The guide column passes through the fixed plate and the lower end is connected to a connecting plate 17 fixed on the upper side of the frame plate. A reset spring 7 is sleeved on the guide column and is located between the connecting plate and the fixed plate, so that the frame plate can be elastically raised and lowered.

[0022] In this embodiment, the two sides of the upper surface of the frame plate are slidably connected with a U-shaped fixing frame 18, one end of the flexible adsorption plate is fixedly connected to the fixing frame on one side, and the other end of the flexible adsorption plate is bypassed by the lower port of the frame plate and turned upward by the side plate on the other side of the frame plate to be fixedly connected to the fixing frame on the other side, and the front and rear parts of the two fixing frames are connected respectively via a tension spring 19. Therefore, when attached to the surface of the aluminum coil, the fixing frame can slide outward, so that the flexible adsorption plate can better fit the curved surface of the aluminum coil.

[0023] In this embodiment, the tension spring may also be replaced by a rubber band.

[0024] In this embodiment, a pair of transverse grooves 20 are respectively provided at the front and rear parts of the fixing frame, and limiting guide pins 21 connected to the frame plate are penetrated in the transverse grooves, so as to better realize the lateral movement of the fixing frame.

[0025] In this embodiment, the front and rear ends of the frame plate are respectively fixed with end plates 8 having arc-shaped recesses, so that the device can better adhere to the surface of the aluminum coil when sucking the label to adhere to the surface of the aluminum coil.

[0026] In this embodiment, the flexible adsorption plate is a flexible nylon cloth evenly distributed with air holes and having a certain elasticity.

[0027] In this embodiment, a cantilever plate 9 extending outward is fixed on one side of the frame plate, and a laser distance sensor 10 and an ultrasonic distance sensor are fixed on the cantilever end of the cantilever plate to detect the distance between the flexible adsorption plate and the aluminum coil.

[0028] In this embodiment, in order to drive the entire device to move, a driving mechanism for driving the frame plate to rotate and flip is also provided on the upper side of the fixed plate, and the driving mechanism includes a gear 11 fixedly connected to the fixed plate, and a rotating shaft 12 is longitudinally penetrated on the gear and connected to the fixed plate for rotation, and the two ends of the rotating shaft are respectively fixedly connected to the vertical plate 13, and the upper end of the vertical plate is fixedly connected to a cylinder 14, and a rack 15 meshing with the gear is fixed on the telescopic rod of the cylinder, so that the fixed plate and the frame plate can be flipped around the rotating shaft by driving the rack to extend and retract by the cylinder. A turntable 16 is fixed on the upper end of the cylinder, and the turntable is driven by a manipulator to drive the entire device to rotate.

[0029] When the device is in use, the negative pressure fan is turned on from the label printing device to wait and adsorb the label. When the aluminum coil is positioned at the labeling position, the robot moves the labeling device to about 400mm close to the outer surface of the aluminum coil label through the set logical motion trajectory. The laser and ultrasonic distance measuring sensors measure the actual distance to the outer surface of the coil. The labeling device will slowly approach the coil surface according to the distance. The labeling device starts to slow down about 100mm outside the surface of the aluminum coil and then approaches the coil at a low speed. When the flexible labeling plate approaches the outer surface of the aluminum coil, the labeling process is achieved without damaging the surface quality of the coil.

[0030] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0031] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0032] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.
