[0031] a fixing plate 10, in which a through hole 101 for the object to be stuck with tape to pass through is provided; a tape sticking rotating ring 20, which is installed on the first side of the fixing plate 10 and is located on the outer edge of the through hole 101, and an installation shaft 201 for installing the tape is provided on the tape sticking rotating ring 20;

[0032] a driving assembly 30, which is connected to the tape sticking rotating ring 20 and is used to drive the tape sticking rotating ring 20 to rotate around its center;

[0033] a tape pressing assembly 40, which includes a pressing arm 401 for pressing the tape tightly, a first moving arm unit for driving the pressing arm 401 to move on the line connecting the center of the tape sticking rotating ring 20, and a second moving arm unit for driving the pressing arm 401 to move along the central axis of the tape sticking rotating ring 20;

[0034] The tape cutting assembly 50 includes a pressure-bearing block 501, a moving block unit, and a cutting unit. The moving block unit is installed on the second side of the fixed plate 10, and the moving end of the moving block unit is connected to the pressure-bearing block 501 to drive the pressure-bearing block 501 to move from the second side of the fixed plate 10 through the accommodation through hole 101 to the first side of the fixed plate 10. During the movement, it abuts against the tape, pulls the tape to the lower side of the pressing arm 401. The cutting unit includes a cutter 502 installed in the pressure-bearing block 501 and a moving cutter assembly connected to the cutter 502 to drive the cutter 502 to extend out of the pressure-bearing block 501 so as to cut the tape when the pressure-bearing block 501 pulls the tape to the lower side of the pressing arm 401.

[0035] Specifically, the working principle of a tape pasting device according to the present invention will be described below with reference to the accompanying drawings.

[0036] As Figure 1 shown, this figure shows the preparatory work before tape pasting. The tape is installed on the tape pasting rotating ring 20 through the installation shaft 201, and the end of the tape is located at the bottom of the pressing arm 401. It should be noted that at this time, the adhesive surface of the tape faces upward and is partially adhered to the bottom of the pressing arm 401. The end of the object to be pasted is placed at the center position of the tape pasting rotating ring 20. In this embodiment, the object to be pasted is a reel.

[0037] As Figure 2 shown, when it is necessary to paste the tape on the reel, the first moving arm unit drives the pressing arm 401 to move downward so that the pressing arm 401 abuts against the reel, thereby limiting and fixing the end of the tape to the outside of the reel. Then, the driving assembly 30 drives the tape pasting rotating ring 20 to rotate, so that the tape rotates with the tape pasting rotating ring 20, and thus the empty reel is preliminarily wound. During the winding process, since the tape is partially adhered to the pressing arm 401 and the adhesive surface of the tape faces upward relative to the reel, the next turn of the tape can effectively adhere to the next turn of the tape.

[0038] As Figure 3 shown, in this embodiment, when the driving assembly 30 drives the tape pasting rotating ring 20 to rotate three to four turns, that is, when the tape is wound around the reel three to four turns, the second moving arm unit drives the pressing arm 401 to move along the central axis of the tape pasting rotating ring 20, that is, along the length direction of the reel, so that the pressing arm 401 disengages from between the two tape loops. After the pressing arm 401 disengages, the first moving arm unit drives the pressing arm 401 to move upward a certain distance. Then, the driving assembly 30 continues to drive the rotating ring to rotate so that the tape continues to wind around the reel again. It should be noted that due to the previous preliminary winding, the tape loops wound around the reel are adhered to each other and are stabilized on the reel due to the tension force. Therefore, it is not necessary to fix them through the pressing arm 401 during the re-winding. In this embodiment, the purpose of the re-winding is to flatten the wrinkles existing between the tape rolls after the pressing arm 401 disengages.

[0039] like Figure 4 As shown, after winding two to three turns again, the block moving unit drives the pressure block 501 to move from the second side of the fixed plate 10 to the bottom of the pressure arm 401, and during the movement, the tape is pulled to move to the bottom of the pressure arm 401, so that the adhesive surface of the tape is again adhered to the bottom of the pressure arm 401; it should be noted that, in this embodiment, since the block moving unit drives the pressure block 501 to move from the second side of the fixed plate 10 to the first side, it can effectively avoid the tape when the glue rotating ring 20 drives the tape to rotate and the reel is wound, thereby facilitating the work of the tape.

[0040] like Figure 5 As shown, when the pressure block 501 moves to the preset position, the knife moving assembly in the cutting unit drives the cutter 502 to extend from the side of the pressure block 501 so that the cutter 502 cuts the tape.

[0041] like Figure 6 As shown, after the cutter 502 cuts off the tape, the knife shifting assembly drives the cutter 502 to reset, the block shifting unit drives the pressure block 501 to reset, and the first arm shifting unit drives the pressure arm 401 to completely reset. At this point, one gluing process is completed; at this time, the tape is adhered to the bottom of the pressure arm 401, and then in the next winding work, there is no need to manually pull the tape to the bottom of the pressure arm 401 again, and then repeat the above-mentioned gluing work.

[0042] In a specific embodiment, the driving assembly 30 includes a first driven wheel 301 and a second driven wheel 302 installed on the first side of the fixed plate 10 and pressed against the rubber rotating ring 20, a driving wheel 303 installed between the first driven wheel 301 and the second driven wheel 302, a transmission belt 304 sleeved on the first driven wheel 301, the second driven wheel 302 and the driving wheel 303, and a driving motor 305 connected to the driving wheel 303 for driving the driving wheel 303 to rotate; wherein, the transmission belt 304 located between the first driven wheel 301 and the second driven wheel 302 is in contact with the outer periphery of the rubber rotating ring 20.

[0043] For more details, see Figure 7 , Figure 8 as well as Figure 9 In the embodiment, when working, the driving motor 305 drives the active wheel 303 to rotate, and then cooperates with the first driven wheel 301 and the second driven wheel 302 to drive the transmission belt 304 to rotate, thereby driving the rubber rotating ring 20 to rotate; further, on the first side of the fixed plate 10, a plurality of limiting pulleys 306 that abut against the rubber rotating ring 20 are provided along the outer periphery of the rubber rotating ring 20, thereby ensuring the stability of the rubber rotating ring 20 during rotation.

[0045] Specifically, please refer to Figure 7 、 Figure 8 and Figure 10 , in this embodiment, the moving frame includes a first connecting arm 402 and a second connecting arm 403 installed on both sides of the glue - applying rotating ring 20, and a third connecting arm 404 installed between the first connecting arm 402 and the second connecting arm 403; the moving frame assembly includes a first cylinder 405 connected to the first connecting arm 402 for driving the first connecting arm 402, and the second connecting arm 403 and the third connecting arm 404 connected thereto, to move towards the center of the glue - applying rotating ring 20, and a first guiding rail 406 installed between the first connecting arm 402 and the fixed plate 10 to enable the first connecting arm 402 to move stably in a fixed direction. During operation, the first cylinder 405 drives the first connecting arm 402 to move, so that the first connecting arm 402 moves in a fixed direction along the first guiding rail 406 on the center line connecting it and the center of the rotating ring, so that the pressing arm 401 located at its bottom can press the tape against the reel as required.

[0046] Specifically, please continue to refer to Figure 7 、 Figure 8 and Figure 10 , there are two pressing arms 401, and the two pressing arms 401 are respectively installed at the bottoms of the first connecting arm 402 and the second connecting arm 403; the second moving arm unit includes a second cylinder 407 connected to the pressing arm 401 for driving the pressing arm 401 to move along the central axis of the glue - applying rotating ring 20.

After the first winding, the second cylinder 407 drives the two pressing arms 401 to move away from each other, so that the pressing arms 401 are separated from the tape.

The second moving assembly has a second moving path for driving the pressure-bearing block 501 to move from the second side of the fixing plate 10 to the first side of the fixing plate 10. During operation, the pressure-bearing block 501 is located on the second side of the fixing plate 10 and is relatively located on the upper side of the adhesive-applying rotating ring 20. After the tape is wound around the reel again, as Figure 3 shown, the tape body is located on one side above the adhesive-applying rotating ring 20 and above the pressure-bearing block 501. At this time, as Figure 4 shown, the pressure-bearing block 501 is driven by the first moving assembly and the second moving assembly to move below the pressing arm 401, and during the movement, the tape is pulled below the pressing arm 401 so that the tape adheres to the pressing arm 401 again. Further, the first moving assembly includes a second guiding rail 503 installed on the second side of the fixing plate 10, inclined downward toward the lower side of the pressing arm 401 along the second side of the fixing plate 10 from one side above the self-adhesive rotating ring 20, a slider 504 slidably installed on the second guiding rail 503, and a third air cylinder 505 installed on the second side of the fixing plate 10 for driving the slider 504 to move along the second guiding rail 503; the second moving assembly is connected to the slider 504.

[0051] In a specific embodiment, the cutter moving assembly includes a fifth cylinder (not shown in the figure) installed in the pressure-bearing block 501 for driving the cutter 502 to extend or retract into the pressure-bearing block 501.
