[0031] The tape pasting assembly 70, the tape pasting assembly 70 is installed above the first tape receiving platform 10 and the second tape receiving platform 20 for pasting and connecting the break of the unwound tape A;

[0032] The first moving assembly and the second moving assembly, the first moving assembly is connected to the first tape receiving platform 10 for driving the first tape receiving platform 10 to move on the path towards the second tape receiving platform 20; The second moving assembly is connected to the pressure module and the tape pasting module for driving the pressure module and the tape pasting assembly 70 to move horizontally above the first tape receiving platform 10 and the second tape receiving platform 20.

[0033] Specifically, the following combines the attached Figures 1 to 4 , to illustrate the working principle of a tape removing device involved in the present utility model;

[0034] Step 1, as Figure 1 , the unwound tape A is input onto the first tape receiving platform 10 along a first preset path under the traction of an external device and passes through the second tape receiving platform 20. At this time, there is a preset interval between the first tape receiving platform 10 and the second tape receiving platform 20. The discharging roller 501 is located below the preset interval, and the rubber pressure roller 502 is located above the preset interval and is aligned with the discharging roller 501; In this embodiment, the unwound tape A is a pole piece tape;

[0035] Step 2, asFigure 2 As shown in the figure, when there is a defective tape B in the unwound tape A, the second tape pressing assembly 40 presses the unwound tape A located on the second tape connecting platform 20, so that the second tape connecting platform 20 stops running the tape. At this time, the lifting unit 503 drives the rubber pressing roller 502 to move downward and abuts against the discharging roller 501 below it. At the same time, the rubber pressing roller 502 and the discharging roller 501 rotate synchronously, so that the defective tape B output from the first tape connecting platform 10 is conveyed to the defective tape B placement area through the rubber pressing roller 502 and the discharging roller 501;

[0036] Step 3, as Figure 3 shown in the figure, when the defective tape B in the unwound tape A is completely pulled to the defective placement area through the rubber pressing roller 502 and the discharging roller 501, at this time, the first tape pressing assembly 30 presses the tape located on the first tape connecting platform 10, so that the first tape connecting platform 10 stops running the tape. At this time, the rubber pressing roller 502 is reset under the drive of the lifting unit 503. Then, the first moving assembly drives the first tape connecting platform 10 to move towards the second tape connecting platform 20 and contacts the second tape connecting platform 20. Subsequently, the cutter 601 (in this embodiment, the cutter 601 is located inside the second tape connecting platform 20) located on the first tape connecting platform 10 / or the second tape connecting platform 20 extends out of the second tape connecting platform 20 under the drive of the knife moving module 602, so as to cut off the defective tape B and separate it from the original unwound tape A;

[0037] Step 4, as Figure 4 shown in the figure, while the cutter 601 cuts off the defective tape B, the second moving assembly drives the tape pasting assembly 70 to move horizontally, so that the tape pasting assembly 70 is aligned with the cut in the vertical direction. Then, the tape pasting assembly 70 moves downward and pastes a single-sided tape on the cut to complete the connection of the tape. After the connection is completed, each device returns to Figure 1 the working state, so that the unwound tape A after removing the defective tape B runs the tape; thus, the removal work of a defective tape B is completed. It should be noted that the tape pasting assembly 70 belongs to the prior art, so this technical solution will not be elaborated herein.

[0038] A tape removal device involved in the present utility model can automatically complete the removal and connection of the defective tape B in the unwound tape A through the settings of the first tape connecting platform 10, the second tape connecting platform 20, the first tape pressing assembly 30, the second tape pressing assembly 40, the discharging assembly 50, the cutting assembly 60, the tape pasting assembly 70, the first moving assembly and the second moving assembly. It has a high degree of automation and fast working efficiency, and is suitable for industrial applications.

[0039] In a specific embodiment, the cutting knife 601 is installed inside one side of the second tape connecting platform 20 close to the first tape connecting platform 10; the knife moving module 602 is used to drive the cutting knife 601 to extend out from the side of the second tape connecting platform 20 to cut off the defective tape B in the unwound tape A; an avoidance groove 603 for the cutting knife 601 to pass through is arranged on one side of the first tape connecting platform 10 close to the second tape connecting platform 20. Specifically, in this embodiment, as Figure 5 shown, through the arrangement of the avoidance groove 603, when the cutting knife 601 extends out of the second tape connecting platform 20 to cut off the defective tape B, it will interfere with the first tape connecting platform 10.

[0040] In a specific embodiment, a brush pressure roller 90 for assisting in discharging is arranged on one side of the discharging roller 501.

[0041] In a specific embodiment, a material receiving frame 100 for receiving the cut defective tape B is arranged below the discharging roller 501.

[0042] In a specific embodiment, the second moving component includes a mounting plate 80 installed above the first tape connecting platform 10 and the second tape connecting platform 20, and a moving module connected to the mounting plate 80 for driving the mounting plate 80 to move horizontally; the pressure roller module and the tape pasting component 70 are respectively installed on both sides of the mounting plate 80. In this embodiment, through the arrangement of the mounting plate 80, the moving module can synchronously move the pressure roller module and the tape pasting component 70, so as to align the glue pressure roller 502 with the discharging roller 501 and align the tape pasting component 70 with the cutting position in an orderly manner without position interference.

[0043] In a specific embodiment, a first color mark sensor 110 and a second color mark sensor 120 are arranged in sequence along the advancing direction of the unwound tape A on the first preset path. Specifically, please refer to Figure 1 , there is a certain distance between the first color mark sensor 110 and the second color mark sensor 120;

[0044] In the process of the above step 2, when the first color mark sensor 110 detects the defective tape B, the control device controls the unwinding device to decelerate to reduce the running speed of the unwound tape A. Then, when the defective tape B newly reaches the second color mark sensor 120, the unwinding device stops running and the device stops. At this time, the second tape pressing component 40 descends and presses the tape on the second tape connecting platform 20. After pressing, the unwinding device starts and maintains a low running speed to continue the subsequent work of step 2, so as to convey the defective tape B to the defective product placement area;

[0045] In step 3, when the second color mark sensor 120 detects a good product tape, the unwind device stops the tape running, the first tape pressing assembly 30 presses down the first tape connecting platform 10, and the rubber pressing roller 502 resets. After completing the actions, the first tape connecting platform 10 is horizontally moved by the first moving assembly to contact the second tape connecting platform 20, and then the defective product tape B is cut off by the cutter 601;

[0046] In step 4, after the defective product tape B is cut off and the taping and connecting assembly 70 performs taping and connecting, the unwind device resumes tape running.

[0047] In this embodiment, through the settings of the first color mark sensor 110 and the second color mark sensor 120, the first color mark sensor 110 is used to preliminarily judge the area and position of the defective product tape B in the unwind tape A during high-speed tape running, and reduce the tape running speed, so that the second color mark sensor 120 can accurately detect the area and position of the defective product tape B, thereby improving the rejection effect of the tape rejection device involved in the present invention on the defective product tape B.

[0048] Further, the first tape pressing assembly 30 and the second tape pressing assembly 40 include a pressing plate for pressing the tape and a driving module for driving the pressing plate to move towards the upper end surface of the first tape connecting platform 10 / the second tape connecting platform 20, so that the pressing plate presses the first tape connecting platform 10 / the second tape connecting platform 20.

[0049] It should be noted that in the technical solution, the first moving assembly is used to horizontally move the first tape connecting platform 10, the moving module is used to horizontally move the mounting plate 80, the lifting unit 503 is used to drive the rubber pressing roller 502 to lift, and the driving module drives the pressing plate to move. Those skilled in the art can achieve this technical purpose through settings such as cylinder driving or motor cooperating with a lead screw, which belongs to the conventional application of the prior art by those skilled in the art, and this technical solution will not be elaborated.

[0050] A tape rejection device involved in the present invention, through the settings of the first tape connecting platform 10, the second tape connecting platform 20, the first tape pressing assembly 30, the second tape pressing assembly 40, the tape discharging assembly 50, the cutting assembly 60, the taping assembly 70, the first moving assembly and the second moving assembly, can automatically complete the rejection and connection of the defective product tape B in the unwind tape A, with high automation degree and fast working efficiency, and is suitable for industrial applications.

[0051] The above embodiments only represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model.
