Specifically, to further improve the efficiency, the rotating shafts 12 are arranged on the mounting base 11 in a spaced side-by-side manner, the side-by-side direction of two adjacent rotating shafts 12 is arranged along the radial direction of the rotating shafts 12, and each rotating shaft 12 is provided with a pick-and-place mechanism 15, an angle limiting assembly 14 and a stepping motor 13; for example, in fig. 1, 3 to 5, there are two rotating shafts 12, so that there are two pick-and-place mechanisms 15, two angle limiting assemblies 14 and two stepping motors 13, so that the automatic label-mounting head 10 has a double-station automatic mounting function, but not limited thereto. More specifically, the following:
as shown in fig. 3 and 6, the initial position trigger 144 is aligned with the sensor 141 when the stop block 142 abuts against the stop block 143, so as to more effectively control the pick-and-place mechanism 15 to precisely return to the initial position, but not limited thereto. In order to enable the pick-and-place mechanism 15 to automatically reset after rotating to the extreme position, the automatic label-pasting head 10 further comprises a sensor 147 and an extreme position trigger part 148 for triggering the sensor 147, wherein the extreme position trigger part 148 is staggered with the initial position trigger part 144 along the rotation direction of the rotating shaft 12, preferably, the extreme position trigger part 148 is also staggered with the initial position trigger part 144 along the axial direction of the rotating shaft 12, and the state is shown in fig. 6, so that the arrangement can provide an avoiding position for the installation of the sensor 141 and the sensor 147 on the mounting seat 11; the sensor 147 is mounted on the mounting base 11 and supported by the mounting base 11, preferably, the sensor 141 and the sensor 147 are each mounted at the U-shaped bracket 16, and the U-shaped bracket 16 is mounted at the top of the mounting base 11, so as to facilitate the mounting arrangement of the sensor 141 and the sensor 147, but not limited thereto; the limit position trigger 148 is located on the rotation shaft 12, but is not limited thereto, and is naturally located on the stopper 142 or on the rotation shaft 12 and the stopper 142 as needed. The initial position trigger 144 aligns with the sensor 141 when the rotating shaft 12 rotates in one of the forward direction and the reverse direction to make the limit block 142 abut against the matching block 143, and the initial position trigger 144 triggers the sensor 141 to operate at this time, so that the operating sensor 141 feeds back a signal to the electric box mechanism 70, and the electric box mechanism 70 controls the stepper motor 13 to stop operating, or controls the stepper motor 13 to drive the rotating shaft 12 to rotate in the direction opposite to the original direction; the limit position trigger 148 is aligned with the sensor 147 when the rotating shaft 12 rotates in the other of the forward direction and the reverse direction to make the limit block 142 abut against the stop block 143, the limit position trigger 148 triggers the sensor 147 to operate, so that the operating sensor 147 feeds back a signal to the electrical box mechanism 70, and the electrical box mechanism 70 controls the stepper motor 13 to drive the rotating shaft 12 to rotate in the direction opposite to the original direction. For example, the initial position trigger 144 and the extreme position trigger 148 may be slot structures or protrusion structures, and the sensor 141 and the sensor 147 may be proximity switches, but not limited thereto.
In fig. 3 to 8, since the fitting block 143 needs to abut against the limiting block 142 in the forward and reverse rotation directions, the limit angle that the rotating shaft 12 can rotate is limited by the size of the fitting block 143, in order to enlarge the limit angle that the rotating shaft 12 can rotate and ensure that the limit angle that the rotating shaft 12 can rotate is less than 360 degrees, the limiting block 142 includes a shaft sleeve 1421 sleeved on the rotating shaft 12 and a protrusion structure 1422 protruding outward from the shaft sleeve 1421 and overlapping with the fitting block 143 in the rotation direction of the rotating shaft 12, preferably, the protrusion structure 1422 protrudes in the radial direction of the rotating shaft 12, and certainly, the protrusion protrudes outward in the axial direction of the rotating shaft 12 according to actual needs, so the limitation is not to be made; the sleeve 1421 is provided with a linkage long slot 145 arranged along the rotation direction of the rotation shaft 12, the rotation shaft 12 is provided with a linkage convex portion 146 extending into the linkage long slot 145, the rotation shaft 12 intermittently links the limiting block 142 to rotate through the cooperation of the linkage long slot 145 and the linkage convex portion 146, so that the limiting block 142 is driven to rotate after the rotation shaft 12 is allowed to rotate for a certain angle relative to the limiting block 142 by the cooperation of the linkage long slot 145 and the linkage convex portion 146, thereby the rotatable limit angle of the rotation shaft 12 is enlarged and can reach the range of 0 to 350 degrees; of course, the linking slot 145 can be opened by the rotating shaft 12 and the linking protrusion 146 can be provided by the stopper 142 according to the actual requirement, so the invention is not limited thereto. It can be understood that in the scheme of allowing the rotating shaft 12 to rotate a certain angle relative to the limiting block 142, the initial position trigger part 144 can only be positioned on the rotating shaft 12; when the stopper 142 is fixedly connected to the rotating shaft 12, the initial position trigger 144 may be located at the rotating shaft 12 and/or the stopper 142.

The working principle of the automatic label pasting equipment is explained with the accompanying drawings: when a product at one of the first station jig 51 and the second station jig 52 needs to be labeled, the automatic label-attaching head 10 moves to a position right above the label at the loading position conveyed by the label feeder 60 under the control of the electronic box mechanism 70 on the moving mechanism 40; next, the automatic label application head 10 takes the label located at the loading position under the control of the electronic box mechanism 70; then, the automatic label sticking head 10 moves to the position right above the product to be stuck under the control of the electric box mechanism 70 on the moving mechanism 40; subsequently, the automatic label attaching head 10 performs angle adjustment under the control of the electronic box mechanism 70, and automatically attaches the label to the product after the angle adjustment. In fig. 1, when the pick-and-place mechanism 15, the stepping motor 13, the angle limiting component 14 and the rotating shaft 12 are two, the label mounting of the product on the second station fixture 52 at this time is designed to be completed by the stepping motor 13, the angle limiting component 14, the rotating shaft 12 and the pick-and-place mechanism 15 on the left side; the label mounting of the product at the first station fixture 51 is designed to be performed by the stepping motor 13, the angle limiting component 14, the rotating shaft 12 and the pick-and-place mechanism 15 on the right side, but not limited to this description.
Compared with the prior art, the stepping motor 13 drives the picking and placing mechanism 15 to rotate through the rotating shaft 12 by means of the coordination of the stepping motor 13, the rotating shaft 12, the picking and placing mechanism 15 and the angle limiting component 14, so that the angle adjustment is carried out before the label is pasted, the picking and placing mechanism 15 automatically pastes the label picked by the picking and placing mechanism 15 on a product after the angle adjustment is in place, the purpose of automatically and accurately pasting the label on the product is realized, and the labor intensity of an operator is reduced; more importantly, since the angle limiting assembly 14 comprises the sensor 141, the limiting block 142, the auxiliary block 143 which cooperates with the limiting block 142 in a blocking manner to limit the rotation angle of the rotating shaft 12, and the initial position triggering portion 144 for triggering the sensor 141, the limiting block 142 is mounted on the rotating shaft 12, the auxiliary block 143 is mounted on the mounting base 11, and the auxiliary block 143 is further stacked on the limiting block 142 along the rotation direction of the rotating shaft 12, such that the limiting block 142 cooperates with the auxiliary block 143 to limit the rotating shaft 12 to rotate in a forward direction or a reverse direction within a range of less than 360 degrees, and the stepping motor 13 is prevented from driving the pick-and-place mechanism 15 to rotate in an unlimited manner (e.g., to rotate in a forward direction or in a reverse direction by more than 360 degrees) through the rotating shaft 12, and the air tube and the line at the pick-and-place mechanism 15 are entangled; meanwhile, by means of the sensor 141 mounted on the mounting seat 11 and the initial position trigger part 144 located on the rotating shaft 12 and/or the limiting block 142, the pick-and-place mechanism 15 can accurately return to the initial position after each label pasting under the cooperation of the stepping motor 13 and the rotating shaft 12, so that accumulated errors caused by inaccurate return of the pick-and-place mechanism 15 to the initial position each time are avoided, and the label pasting accuracy of the automatic label pasting head 10 of the present invention is further improved.
It should be noted that the specific structure of the label feeder 60, the electrical box mechanism 70 and the station fixture 50 is well known in the art, and therefore, the detailed description thereof is omitted.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims.
