[0040] Among them, in this embodiment, see Figure 4-7 As shown, the turntable shaft assembly 21 includes a turntable shaft 211, and the turntable shaft 211 is rotatably arranged on the support frame 4 through a bearing seat 212; 16 first vacuum holes 2111 are provided on the turntable shaft 211, and two first connecting holes 2121 and one second connecting hole 2122 are provided on the bearing seat 212. Of course, the number of the first vacuum holes 2111 and the first connecting holes 2121 is only one embodiment, and is not intended to limit the scope of the present application. When setting, the first vacuum holes 2111 and the first connecting holes 2121 can also be set to other numbers, for example: 14 first vacuum holes 2111 are provided, and one first connecting hole 2121 is provided, as long as the requirements can be met; and a copper sleeve 213 is provided between the turntable shaft 211 and the bearing seat 212, and the copper sleeve 213 is pressed into the bearing The copper sleeve 213 is provided with a first notch 2131 and a second notch 2132, wherein the first notch 2131 is a long strip-shaped notch, and the second notch 2132 is a circular notch. When the copper sleeve 213 is rotated, there are always six consecutive first vacuum holes 2111 connected with two first connecting holes 2121 through the first notch 2131, and there is always one first vacuum hole 2111 connected with the second connecting hole 2122 through the second notch 2132. When the copper sleeve 213 is in operation, the first connecting hole 2121 is connected with a group of the vacuum generators 26 through corresponding pipes, and the second connecting hole 2122 is connected with another group of the vacuum generators 26 through corresponding pipes.

[0041] It should be noted that, in this embodiment, see Figure 7 As shown (the arrow in the figure indicates the rotation direction of the turntable shaft assembly 21 when the turntable shaft assembly 21 is glued), when the turntable shaft assembly 21 is installed, the second notch 2132 is located below the copper sleeve 213.

[0042] In addition, in this embodiment, see Figure 8-10As shown, the turntable assembly 22 includes a turntable 221 connected to the turntable shaft 211 and capable of rotating synchronously with the turntable shaft 211, the turntable 221 is provided with second vacuum holes 2211 corresponding to the first vacuum holes 2111, and the outer surface of the turntable 221 is circumferentially provided with a circle of suction cups 222 corresponding to the second vacuum holes 2211, so that the first vacuum holes 2111 correspond to the suction cups 222 one by one, that is, in this embodiment, 16 second vacuum holes 2211 and 16 suction cups 222 are provided, and the suction cups 222 are each provided with suction holes 2225 for adsorbing the tape, and the suction holes 2225 in the suction cups 222 are connected to the corresponding second vacuum holes 2211. When the turntable assembly 22 is connected to the turntable shaft 211, see Figure 11-12 As shown, each group of the first vacuum holes 2111 and the corresponding second vacuum holes 2211 are interconnected. Therefore, under the drive of the turntable shaft 211, when all the suction cups 222 rotate with the turntable 221, the vacuum generator 26 connected to the first connection hole 2121 through the corresponding pipeline can always control six consecutive suction cups 222 to adsorb the tape, and the vacuum generator 26 connected to the second connection hole 2122 through the corresponding pipeline can always control one suction cup 222 to adsorb the tape. It should be noted that in this embodiment, when 16 suction cups 222 rotate with the turntable 221, when one When one of the suction cups 222 is controlled by the vacuum generator 26 to adsorb the tape, the position of the suction cup 222 is defined as the gluing position, that is, all the suction cups 222 rotate to this position with the turntable 221 during the rotation process and then glue the product. When six consecutive suction cups 222 are controlled by the vacuum generator 26 to adsorb the tape, the position of the six suction cups 222 is defined as the tape adsorption waiting position, that is, all the suction cups 222 rotate into this position range with the turntable 221 during the rotation process and then start to adsorb the tape and drive the tape to rotate, and enter the gluing position after rotating out of the tape adsorption waiting position for gluing. In order to prevent the suction cup 222 from sticking to the tape when attaching the product at the gluing position, a guide plate 223 is provided at the front end of the turntable 221 to allow the suction cup 222 to float inside and outside the turntable 221, and the guide plate 223 is fixed to the support frame 4 through a guide support 224.

[0043] Among them, in this embodiment, see Figure 13-14As shown, the suction cup 222 is composed of a sliding suction cup 2221 and a silicone suction cup 2222; the sliding suction cup 2221 can be installed in the turntable 221 in an inward and outward floating manner, and the silicone suction cup 2222 is installed on the sliding suction cup 2221; the sliding suction cup 2221 is provided with a connecting hole 22211 penetrating the upper and lower end surfaces thereof, and the silicone suction cup 2222 is provided with three groups of air holes 22221 penetrating the upper and lower end surfaces thereof, the connecting hole 22211 and the air holes 22221 are connected, and the two together constitute the adsorption hole 2225; wherein, the air holes 22221 form three openings on the upper end surface of the silicone suction cup 2222, but are not limited to three, and more openings can also be provided, and can be provided according to needs when in use.

[0044] See also Figure 13-15 As shown, in order to realize the floating of the sliding suction cup 2221 inside and outside the rotating disk 221, a guide shaft 2223 is provided on the side wall of the sliding suction cup 2221, and a guide groove 2231 is provided on the guide plate 223. The direction of the guide groove 2231 is the same as the trajectory of the rotating disk 221 driving the suction cup 222 to rotate, but a convex point 2232 is formed in the guide groove 2231; when the guide plate 223 is installed, the guide shaft 2223 extends from the side wall of the rotating disk 221 and then extends into the guide groove 2231, and the guide shaft 2223 extends into the guide groove 22 The shaft section in 31 is provided with a bushing 2224, and the bushing 2224 is made of nylon; when the suction cup 222 rotates with the turntable 221, the guide shaft 2223 is driven to run along the guide groove 2231, and at the convex point 2232, the sliding suction cup 2221 is driven by the guide shaft 2223 to move to the outside of the turntable 221, that is, to extend out of the turntable 221; in this embodiment, the convex point 2232 is arranged relative to the glue-applying position of the turntable 221, so that the suction cup 222 can extend from the turntable 221 when it rotates to the glue-applying position, so as to avoid adhesion when sticking the tape.

[0045] For further information, see Fig.11 As shown, the glue-laminating module 2 also includes an origin sensing photoelectric sensor 27 and an origin sensing photoelectric sheet 28 matched with the origin sensing photoelectric sensor 27; and in the present embodiment, the origin sensing photoelectric sensor 27 is arranged on the bearing seat 212, and the origin sensing photoelectric sheet 28 is arranged on the turntable shaft 211. By matching the origin sensing photoelectric sensor 27 and the origin sensing photoelectric sheet 28, the mechanism can be quickly reset to the origin.

[0046] For further information, see Fig.16As shown, the cutter module 3 includes a slide cylinder 31 fixed on the support frame 4 and a pair of cutters 32 for cutting the tape, and the cutter 32 is fixed on the slide of the slide cylinder 31 through a mounting seat 33; during operation, the cutter module 3 divides the tape in the tape adsorption and pasting position, so that when the suction cup 222 in the tape adsorption and pasting position enters the glue pasting position, the tape adsorbed by the suction cup 222 is in a divided state with the original tape, which is convenient for the attachment of the tape.

[0047] Furthermore, a switch button module 6 is also provided on the support frame 4; the switch button module 6 includes a start control switch 61 and an origin reset switch 62 for controlling the mechanism to return to the origin; the start control switch 61 and the origin reset switch 62 are fixed on the support frame 4 through corresponding support seats.

[0048] The working principle of the utility model is as follows:

[0049] During the gluing operation, firstly, the origin reset switch 62 is pressed to drive the motor 24 to run, and the turntable shaft 211 is driven to rotate through the synchronous pulley assembly 23. At this time, the turntable assembly 22 rotates synchronously with the turntable shaft 211. When the origin sensing photoelectric sensor 27 senses the origin sensing photoelectric sheet 28, the drive motor 24 stops running. Then, the tape on the material tray 1 is manually inserted into the turntable assembly 22. Then, the start control switch 61 is pressed to start the vacuum generator 26. The suction cup 222 in the tape adsorption position adsorbs the tape, and the cutting die is pressed. Group 3 divides the tape adsorbed by the suction cup 222 in the tape adsorption waiting position, and the driving motor 24 drives the turntable 221 to rotate by driving the turntable shaft 211 to rotate, so that the suction cup 222 in the tape adsorption waiting position enters the gluing position, and after the suction cup 222 enters the gluing position, the driving motor 24 stops running. At this time, the suction cup 222 that enters the gluing position is extended out of the turntable 221 with the adsorbed tape under the action of the convex point 2232, and the Z-axis module 5 drives the gluing module 2 to descend through the supporting frame 4 to achieve the attachment of the tape.

[0050] Among them, after the attachment is completed, the vacuum generator 26 connected to the second connecting hole 2122 through the corresponding pipeline stops running, and the suction cup 222 in the gluing position stops adsorbing the tape. After the Z-axis module 5 drives the gluing module 2 to reset through the supporting frame 4, the vacuum generator 26 connected to the second connecting hole 2122 is started again, and the driving motor 24 continues to drive the turntable shaft 211 to rotate. At this time, the suction cup 222 in the gluing position is rotated out of the gluing position; and a group of suction cups 222 located at the downstream of the tape adsorption and sticking position rotates into the gluing position, and a group of suction cups 222 adjacent to the upstream of the tape adsorption and sticking position rotates into the tape adsorption and sticking position.

[0051] It should be noted that, after the suction cup 222 in the glue sticking position is rotated out of the glue sticking position, the first vacuum hole 2111 connected to the suction cup 222 is disconnected from the second connection hole 2122, stops adsorbing the tape, and enters the next cycle driven by the turntable 221; and when a group of suction cups 222 located at the most downstream of the tape adsorption waiting position rotates into the glue sticking position, the first vacuum hole 2111 connected to the suction cup 222 is gradually converted from being connected to the first connection hole 2121 to being connected to the first connection hole 2122. The second connecting hole 2122 is fully connected, that is, when the suction cup 222 rotates from the tape adsorption and sticking position to the glue sticking position, the suction cup 222 starts to connect to the second connecting hole 2122 before it is completely disconnected from the first connecting hole 2121, thereby preventing the tape adsorbed by the suction cup 222 from falling off; and when a group of suction cups 222 immediately upstream of the tape adsorption and sticking position rotates into the tape adsorption and sticking position, the suction cup 222 is connected to the first connecting hole 2121 and starts to adsorb and pull the tape.

[0052] In addition, it should be noted that the cutter module 3 cuts the tape in the tape adsorption and pasting position to ensure that the tape adsorbed by the suction cup 222 is separated from the main tape before the suction cup 222 in the adsorption and pasting position enters the glue pasting position.

[0053] 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. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
