[0016] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figures 1 to 5 As shown, the tape gluing device of the present invention includes a frame 1 and a tape conveyor line 2, a gluing mechanism 3, a film surface adjustment mechanism 4, a detection mechanism 5 and a controller respectively arranged on the frame 1. The gluing mechanism 3, the film surface adjustment mechanism 4 and the detection mechanism 5 are arranged in sequence along the tape conveyor line 2. The controller controls the tension applied to the tape by the film surface adjustment mechanism 4 and the feeding speed of the tape conveyor line 2 according to the lateral thickness difference and humidity value detected by the detection mechanism 5 after the tape is glued.

[0018] From the above description, it can be seen that the beneficial effects of the present invention are: the tape gluing device and the gluing method, when in use, the controller controls the tape conveyor line 2 to convey the tape at a preset speed, the tape first passes through the gluing mechanism 3 for gluing, and then the detection mechanism 5 is used to detect the transverse thickness difference and humidity value of the tape after gluing and send them to the controller, the controller controls the tension applied to the tape by the film surface adjustment mechanism 4 according to the transverse thickness difference, increases the tension of the tape on the thick side, and reduces the tension of the tape on the thin side, and at the same time, the controller controls the feeding speed of the tape conveyor line 2 according to the humidity value, and increases the feeding speed of the tape when the moisture content of the tape is lower than the preset value, thereby achieving thickness consistency of the tape after gluing in the transverse direction and improving product quality.

[0019] In an optional embodiment, the gluing mechanism 3 includes a gluing roller 31 provided on the frame 1 , and the film surface adjustment mechanism 4 is used to press the adhesive tape into contact with the upper surface of the gluing roller 31 .

[0020] From the above description, it can be seen that the glue coating roller 31 wraps the glue liquid in the glue pool onto the surface and then contacts the tape, so that the tape surface can be glued. The gap value between the tape surface and the glue coating roller 31 can be adjusted through the film surface adjustment mechanism 4, thereby changing the glue thickness of the tape.

[0021] In an optional embodiment, the film surface adjustment mechanism 4 includes a fixed roller 41 and a lifting roller 42 arranged on the frame 1. The fixed roller 41 and the lifting roller 42 are both located on one side of the glue coating roller 31 along the feeding direction of the tape conveyor line 2. The fixed roller 41 and the lifting roller 42 jointly apply tension to the glued tape.

[0022] From the above description, it can be seen that the fixed roller 41 fixes and supports the tape, and the movement of the lifting roller 42 toward the side of the fixed roller 41 will stretch the tape, making the thick and loose tape thinner and tighter, and adjusting the tape thickness by tension, thereby changing the glue thickness.

[0023] In an optional embodiment, the membrane surface adjustment mechanism 4 further includes a lifting frame 43 and a servo motor 44. The two ends of the lifting roller 42 are connected to the frame 1 for lifting and sliding through a set of lifting frames 43. The servo motor 44 drives the lifting frame 43 to lift and slide on the frame 1 through a screw.

[0024] As can be seen from the above description, the servo motor 44 is used to drive the lifting frame 43 to move up and down and slide, thereby fine-tuning the height of the lifting roller 42 to achieve precise adjustment of the surface tension of the tape.

[0025] In an optional embodiment, three lifting rollers 42 are arranged on the lifting frame 43 at intervals in the horizontal direction, and a fixed roller 41 is provided below two adjacent lifting rollers 42 .

[0026] From the above description, it can be seen that after repeated tests, when the number of lifting rollers 42 is three and the number of fixed rollers 41 is two, the control of the surface tension of the tape is most accurate and the overall thickness of the tape after glue coating is most uniform.

[0027] In an optional embodiment, a balancing roller 11 is provided on the frame 1 at one side of the fixed roller 41 and the lifting roller 42 along the feeding direction of the tape conveyor line 2 .

[0028] As can be seen from the above description, the function of the balancing roller 11 is to improve the stability of the process of adjusting the surface tension of the adhesive tape.

[0029] In an optional embodiment, the detection mechanism 5 includes a thickness detector 51 and a moisture content detector 52 installed on the frame 1 and connected to the controller.

[0030] As can be seen from the above description, the thickness detector 51 is used to detect the thickness of the tape in the width direction, and the moisture content detector 52 is used to detect the moisture content of the tape.

[0031] In an optional embodiment, the frame 1 is provided with a reciprocating frame 12 along a direction perpendicular to the feeding direction of the tape conveyor line 2 , and the thickness detector 51 and the moisture content detector 52 are each connected to the frame 1 through a set of reciprocating frames 12 .

[0032] As can be seen from the above description, the reciprocating frame 12 enables the thickness detector 51 and the moisture content detector 52 to monitor the thickness value and moisture content of the tape in the width direction in real time.

[0033] In an optional embodiment, the tape conveyor line 2 includes a feeding motor and a feeding roller group arranged on the frame 1. The feeding motor drives the feeding roller group to rotate and convey the tape. The feeding motor is connected to the controller.

[0034] As can be seen from the above description, the feeding motor is used to control the conveying speed of the feeding roller group.

[0035] The gluing method for a tape gluing device comprises the following steps: At the same time, the transverse thickness difference and humidity value of the tape after glue coating are detected, the tension of the tape on the thick side is increased, and the tension of the tape on the thin side is reduced. When the moisture content of the tape is higher than the preset value, the feeding speed of the tape is reduced, and when the moisture content of the tape is lower than the preset value, the feeding speed of the tape is increased.

[0036] From the above description, it can be seen that the beneficial effect of the present invention is that: the tape gluing method is to control the tape conveyor line 2 to convey the tape at a preset speed through the controller, and the tape is first coated with glue by the gluing mechanism 3, and then the transverse thickness difference and humidity value of the tape after gluing are detected by the detection mechanism 5 and sent to the controller. The controller controls the tension applied to the tape by the film surface adjustment mechanism 4 according to the transverse thickness difference, increases the tension of the tape on the thick side, and reduces the tension of the tape on the thin side. At the same time, the controller controls the feeding speed of the tape conveyor line 2 according to the humidity value, and increases the feeding speed of the tape when the moisture content of the tape is lower than the preset value, thereby achieving thickness consistency of the tape after gluing in the transverse direction and improving product quality.

Each end of the lifting roller 42 is connected to the frame 1 via a set of lifting frames 43 for upward and downward movement. The servo motor 44 drives the lifting frames 43 via a screw to move the lifting frames 43 upward and downward on the frame 1. Three lifting rollers 42 are arranged horizontally on the lifting frames 43, with a fixed roller 41 positioned below and between two adjacent lifting rollers 42.
