[0036] Among them, in this embodiment, see Figure 10-11 As shown, the suction cup assembly 22 includes a sliding suction cup 221 and a silicone suction cup 222. The sliding suction cup 221 is arranged in the turntable 21 and can move in the turntable 21 through the guide plate 23. The silicone suction cup 222 is located at the upper end of the sliding suction cup 221, and the silicone suction cup 222 is penetrated in the sliding suction cup 221 and is sealed and connected to the sliding suction cup 221. The silicone suction cup 222 is used to adsorb the tape. A connecting hole 2211 is provided in the sliding suction cup 221. The silicone suction cup 222 is provided with a glue suction hole 2221, and the connecting hole 2211 and the glue suction hole 2221 constitute the suction hole 223; the upper end surface of the silicone suction cup 222 is provided with a suction groove 2222, and the glue suction hole 2221 forms at least one group of suction ports for adsorbing the tape on the upper end surface of the silicone suction cup 222, and the suction groove 2222 is connected to the suction port, and the suction groove 2222 can effectively improve the suction surface of the silicone suction cup 222 for adsorbing the tape, thereby preventing the tape from falling off during the adsorption process.

[0037] In this embodiment, in order to prevent the suction cup assembly 22 from rotating with the rotating disk 21, the suction cup assembly 22 may rotate by itself. Figure 8 and Figure 10-11 As shown, the turntable 21 is provided with U-shaped grooves 212 corresponding to the suction cup assemblies 22 one by one, and each group of the sliding suction cups 221 is provided with a guide shaft 224 accommodated in the corresponding U-shaped groove 212; and in order to realize that the guide plate 23 drives the sliding suction cups 221 to float in the turntable 21, see Fig.12As shown, a guide groove 231 adapted to the guide shaft 224 is formed on the guide plate 23, and the direction of the guide groove 231 is the same as the trajectory of the rotation of the suction cup assembly 22 driven by the turntable 21, but a convex point 232 is formed in the guide groove 231. When the guide plate 23 is installed, the guide shaft 224 extends from the turntable 21 and then extends into the guide groove 231, and a bushing 225 is sleeved on the outer surface of the guide shaft 224 extending into the guide groove 231, and the bushing 225 is made of nylon bushing; when the suction cup assembly 22 rotates with the turntable 21, the guide shaft 224 runs along the guide groove 231, and when it runs to the convex point 232, the sliding suction cup 221 is driven by the guide shaft 224 to move toward the outside of the turntable 21 along the corresponding U-shaped groove 212, thereby driving the sliding suction cup 221 to extend out of the turntable 21.

[0038] See also Figure 1-2 As shown, another embodiment of the utility model provides a glue-applying rotating head, comprising the rotating shaft mechanism 1 and the rotating disk mechanism 2; when connected, the rotating disk 21 of the rotating disk mechanism 2 is arranged on the output end of the rotating shaft 11 of the rotating shaft module 1, so that the rotating disk module 2 can rotate synchronously with the rotating shaft module 1 under the drive of the rotating shaft module 1; at this time, continue to refer to Figure 2 As shown, each group of the first vacuum holes 111 and its corresponding second vacuum holes 211 are interconnected, so when all the suction cup assemblies 22 rotate with the turntable 21 under the drive of the rotating shaft 11, in this embodiment, the two groups of the first connecting holes 121 can always maintain communication with the six consecutive groups of the suction cup assemblies 22 through the first notch 131, and the second connecting holes 122 can always maintain communication with one group of the suction cup assemblies 22 through the second notch 132; it should be noted that, in this embodiment, when 16 groups of the suction cup assemblies 22 rotate with the turntable 21, when one group of the suction cup assemblies 22 is connected to the second connecting holes 122, the position of the suction cup assemblies 22 is defined as It is the gluing position, that is, all the suction cup assemblies 22 rotate to this position with the turntable 21 during the rotation process, and glue is applied to the product. When six consecutive groups of the suction cup assemblies 22 are connected to the second connecting hole 122, the position of these six groups of the suction cup assemblies 22 is defined as the tape adsorption waiting position, that is, all the suction cup assemblies 22 rotate into this position range with the turntable 21 during the rotation process, and start to adsorb the tape and pull the tape to rotate, and enter the gluing position after rotating out of the tape adsorption waiting position for gluing. It should also be noted that the convex point 232 is arranged relative to the gluing position, so that when the suction cup assembly 22 rotates to the gluing position, it extends out from the turntable 21 for tape attachment to avoid adhesion during tape application.

[0039] See also Fig.13 As shown in the figure (label A in the figure represents the driving motor; label B in the figure represents the vacuum generator connection; label C in the figure represents the cutter; label D in the figure represents the up and down lifting mechanism; label E in the figure represents the present glue-applying rotating head), before use, the driving motor, the vacuum generator connection, the cutter and the present glue-applying rotating head are all arranged on the up and down lifting mechanism. At this time, the input end of the rotating shaft 11 in the turntable module 2 is connected to the driving motor, and the first connecting hole 121 and the second connecting hole 122 on the bearing seat 12 are respectively connected to a vacuum generator through corresponding pipes.

[0040] When gluing a product, the tape is manually passed through the turntable module 2. At this time, the suction cup assembly 22 in the tape adsorption waiting position adsorbs the tape under the action of the vacuum generator connected to the first connecting hole 121; then the driving motor is started, and the suction cup assembly 22 rotates along with the turntable 21 driven by the rotating shaft 11. At this time, the suction cup assembly 22 located at the gluing position is rotated out of the gluing position; and a group of suction cup assemblies 22 located at the most downstream of the tape adsorption waiting position rotates into the gluing position, and in the process of rotating into the gluing position, under the action of the convex point 232, extends out of the turntable 21 to attach the tape to the product; and a group of suction cup assemblies 22 adjacent to the most upstream of the tape adsorption waiting position rotates into the tape adsorption waiting position to adsorb the tape.

[0041] Among them, it should be noted that when a group of suction cup assemblies 22 completely enters the glue sticking position, at this time, the suction cup assembly 22 is extended to the maximum under the action of the protrusion 232; and after completely entering the glue sticking position, the drive motor stops running, and the up and down lifting mechanism starts. Driven by the up and down lifting mechanism, the glue sticking rotating head is driven to descend as a whole, and after the tape adsorbed on the suction cup assembly 22 is attached to the product, the vacuum generator connected to the second connecting hole 122 stops running; then the up and down lifting mechanism moves upward and resets to the initial position, and the vacuum generator connected to the second connecting hole 122 is started again, and the drive motor is also started again, driving the turntable 21 to rotate, and a round of tape sticking operation is performed.

[0042] In addition, it should be noted that after the suction cup assembly 22 in the glue sticking position is rotated out of the glue sticking position, the suction cup assembly 22 is disconnected from the second connecting hole 122, stops adsorbing the tape, and enters the next cycle driven by the turntable 21; and when a group of suction cup assemblies 22 located at the most downstream of the tape adsorption and sticking position rotates into the glue sticking position, the suction cup assembly 22 is gradually transformed from being connected to the first connecting hole 121 to being completely connected to the second connecting hole 122, that is, in the process of the suction cup assembly 22 rotating from the tape adsorption and sticking position to the glue sticking position, the suction cup assembly 22 starts to connect to the second connecting hole 122 before being completely disconnected from the first connecting hole 121, thereby preventing the tape adsorbed by the suction cup assembly 22 from falling off; and when a group of suction cup assemblies 22 located at the most upstream of the tape adsorption and sticking position rotates into the tape adsorption and sticking position, the suction cup assembly 22 is connected to the first connecting hole 121 and starts to adsorb and pull the tape.

[0043] In addition, it should be noted that after the tape is adsorbed in the tape adsorption and pasting position, the cutter cuts the tape in the tape adsorption and pasting position so that the adsorbed tape of the suction cup assembly 22 in the tape adsorption and pasting position is separated from the original tape before entering the glue pasting position.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
