The various technical features in the creation of the present invention can be combined interchangeably without conflicting with each other.

[0031] See Figure 1-4The preferred embodiment of the present invention provides a tape conveying mechanism 1, comprising an unwinding assembly 11, a rewinding assembly 12, a transmission assembly 13, and an adjustment assembly 14; the unwinding assembly 11 is used to unwind the tape; the rewinding assembly 12 is used to rewind the release paper on the tape; the transmission assembly 13 comprises a transmission drive 131, a transmission roller 132, a first pressure roller 133, and a second pressure roller 134, the first pressure roller 133 is located on the side of the transmission roller 132 close to the unwinding assembly 11, the second pressure roller 134 is located on the side of the transmission roller 132 close to the rewinding assembly 12, the transmission roller 132, the first pressure roller 133 and the second pressure roller 134 are parallel to each other in their axes, and the transmission drive member 131 is used to drive the transmission roller 132 to rotate so that the tape is transported between the transmission roller 132 and the first pressure roller 133, and the release paper on the tape is transported between the transmission roller 132 and the second pressure roller 134; the adjustment component 14 includes an anti-sticking roller 141, a guide member 142 and a displacement sensor 143, the anti-sticking roller 141 is slidably connected to the guide member 142, the anti-sticking roller 141 is used to transport the adhesive part of the tape, and the displacement sensor 143 is used to detect the sliding distance of the anti-sticking roller 141 relative to the guide member 142. The adhesive tape is unwound by the unwinding assembly 11 and positioned between the first pressure roller 133 and the transport roller 132. The transport roller 132 then conveys the adhesive tape to the anti-sticking roller 141. Simultaneously, the release paper on the tape is positioned between the second pressure roller 134 and the transport roller 132. The transport roller 132 conveys the release paper to the rewinding assembly 12, which then rewinds the release paper. The adhesive portion of the tape is then conveyed to the taping device via the anti-sticking roller 141. The taping device exerts a pulling force on the adhesive portion, allowing the anti-sticking roller 141 to slide on the guide 142. The sliding distance of the anti-sticking roller 141 relative to the guide 142 is detected by the displacement sensor 143. This allows the determination of whether the tape conveying speed is consistent with the substrate conveying speed of the taping device. This allows the tape conveying speed or the substrate conveying speed to be adjusted accordingly to ensure consistency between the two.

[0032] The guide member 142 includes a slide rail 144 and a slider 145. The slider 145 is slidably connected to the slide rail 144. The anti-sticking roller 141 is installed on the slider 145. The slide rail 144 is vertically arranged. The anti-sticking roller 141 is lower than the transmission roller 132. The anti-sticking roller 141 can tighten the adhesive part of the tape. The anti-sticking roller 141 drives the slider 145 to slide relative to the slide rail 144. The friction between the slider 145 and the slide rail 144 is small, and a small pulling force can cause the two to move relative to each other, which is conducive to precisely controlling the speed at which the tape-attaching equipment conveys the substrate.

[0033] The unwinding assembly 11 includes a hysteresis brake 111, a first unwinding synchronous wheel 112, an unwinding synchronous belt 113, a second unwinding synchronous wheel 114, and an unwinding reel 115. The rotating shaft of the hysteresis brake 111 is connected to the first unwinding synchronous wheel 112, which is connected to the second unwinding synchronous wheel 114 via the unwinding synchronous belt 113. The second unwinding synchronous wheel 114 is connected to the unwinding reel 115. When the tape applying device is started, it drives the unwinding reel 115 to rotate, which in turn drives the second unwinding synchronous wheel 114 to rotate. Under the action of the unwinding synchronous belt 113, the first unwinding synchronous wheel 112 rotates. The hysteresis brake 111 is used to control the torque of the first unwinding synchronous wheel 112.

[0034] The winding assembly 12 includes a winding motor 121, a first winding synchronous wheel 122, a first winding synchronous belt 123, a second winding synchronous wheel 124, a damper 125, a damping synchronous wheel 126, a second winding synchronous belt 127, a third winding synchronous wheel 128, and a winding reel 129. The rotating shaft of the winding motor 121 is connected to the first winding synchronous wheel 122, the first winding synchronous wheel 122 is connected to the second winding synchronous wheel 124 through the first winding synchronous belt 123, the driving rotor of the damper 125 is connected to the second winding synchronous wheel 124, the driven rotor of the damper 125 is connected to the damping synchronous wheel 126, the damping synchronous wheel 126 is connected to the third winding synchronous wheel 128 through the second winding synchronous belt 127, and the third winding synchronous wheel 128 is connected to the winding reel 129. The winding motor 121 is started, and its shaft drives the first winding synchronous wheel 122 to rotate. Under the action of the first winding synchronous belt 123, the second winding synchronous wheel 124 rotates, and drives the damper 125 to rotate, thereby driving the damper 125 synchronous wheel to rotate, and drives the third winding synchronous wheel 128 to rotate under the action of the second winding synchronous belt 127. The third winding synchronous wheel 128 drives the winding reel 129 to rotate, realizing the winding of the release paper. Under the action of the damper 125, it is conducive to the smooth rotation of the winding reel 129.

[0035] The transmission drive 131 includes a transmission motor 135, a first transmission synchronous pulley 136, a transmission synchronous belt 137, and a second transmission synchronous pulley 138. The transmission motor 135 has a rotating shaft connected to the first transmission synchronous pulley 136, which is connected to the second transmission synchronous pulley 138 via the transmission synchronous belt 137. The second transmission synchronous pulley 138 is connected to the transmission roller 132. When the transmission motor 135 is activated, its rotating shaft drives the first transmission synchronous pulley 136 to rotate. The transmission synchronous belt 137 drives the second transmission synchronous pulley 138 to rotate, which in turn drives the transmission roller 132 to rotate, enabling the transmission roller 132 to transport the adhesive tape and release paper.

[0036] The tape conveying mechanism 1 also includes a vertical plate 15, on which two brackets 151 are provided. The first pressure roller 133 and the second pressure roller 134 are rotatably connected to the two brackets 151 respectively. The axial direction of the first pressure roller 133 and the axial direction of the second pressure roller 134 are both perpendicular to the vertical plate 15. During the transmission process, the tape and the release paper are both perpendicular to the vertical plate 15. Setting the axial direction of the first pressure roller 133 and the axial direction of the second pressure roller 134 to be perpendicular to the vertical plate 15 is conducive to preventing the tape and the release paper from being skewed and wrinkled.

[0037] See Figure 4 Specifically, the bracket 151 includes a fixed block 152, a guide shaft 153, and a pressure rod 154. The fixed block 152 is mounted on the vertical plate 15. One end of the pressure rod 154 is configured in a Y-shape and is rotatably connected to the first pressure roller 133 or the second pressure roller 134. The pressure rod 154 is rotatably connected to the fixed block 152 and is provided with a guide hole 155. One end of the guide shaft 153 is fixedly connected to the fixed block 152, and the other end passes through the guide hole 155. There is a gap between the guide shaft 153 and the guide hole 155. A compression spring 156 is sleeved on the guide shaft 153 and abuts between the pressure rod 154 and the fixed block 152. During the entire conveying process, the pressure rod 154 rotates slightly relative to the fixed block 152. Under the action of the two compression springs 156, the tape and release paper are elastically clamped between the pressure roller and the conveying roller 132, facilitating the conveying of the tape and release paper.

[0038] The tape conveying mechanism 1 further includes a plurality of tape rollers 16, which are respectively located between the unwinding assembly 11 and the transmission roller 132, between the transmission roller 132 and the anti-sticking roller 141, and at the output end of the anti-sticking roller 141. These tape rollers 16 facilitate the transmission of the tape, the release paper, and the adhesive portion of the tape.

[0039] See Figure 5-6 The preferred embodiment of the present invention further provides a tape conveying device, comprising a support plate 17 and several tape conveying mechanisms 1 of the aforementioned embodiment, arranged in a straight line on the support plate 17. The device is capable of conveying multiple rolls of tape at a time, and uses a displacement sensor 143 to detect the sliding distance of the anti-sticking roller 141 relative to the guide member 142 to determine whether the tape conveying speed is consistent with the substrate conveying speed of the taping device. This speed can be used to adjust the tape conveying speed or the substrate conveying speed to ensure consistency between the two.

[0040] The tape conveying equipment also includes a correction mechanism 18, and several tape conveying mechanisms 1 are connected to the correction mechanism 18. The correction mechanism 18 is used to adjust the position of each tape conveying mechanism 1. When the position of the tape conveying mechanism 1 is offset, the correction mechanism 18 can adjust it to the correct position to ensure that the position of the output tape is consistent with the position of the substrate.

[0041] Specifically, the deflection correction mechanism 18 includes a guide rail 181, several lead screw motors 182, and several ball screws 183. The ball screws 183 include ball screws 184 and ball nuts 185. The axial directions of the ball screws 184 are parallel to each other, and the length direction of the guide rail 181 is parallel to the axial direction of the ball screws 184. The several tape conveying mechanisms 1 are all slidably connected to the guide rail 181, and the several tape conveying mechanisms 1 are respectively connected to the ball nuts 185. The rotating shafts of the several lead screw motors 182 are respectively connected to the ball screws 184. When the lead screw motor 182 is started, its rotating shaft drives the ball screws 184 to rotate, and the ball nuts 185 move relative to the ball screws 184, thereby driving the tape conveying mechanisms 1 to slide along the guide rail 181 to achieve the purpose of adjusting the spacing between the tape conveying mechanisms 1. The ball screws 183 can accurately control the movement distance of the unwinding mechanism, with high precision and smooth movement.

[0042] Working principle: After the film laminating equipment is started, it drives the unwinding reel 115 to unwind the tape. At the same time, the winding motor 121 is started, driving the winding reel 129 to wind up the release paper. The transmission motor 135 drives the transmission roller 132 to rotate. The tape is transported between the first pressure roller 133 and the transmission roller 132. When passing through a tape roller 16, the release paper is separated from the adhesive part of the tape. The release paper is transported between the second pressure roller 134 and the transmission roller 132 and is wound by the winding reel 129. The adhesive part is tensioned by the anti-sticking roller 141 and is transported to the film laminating equipment after being tensioned by several tape rollers 16. During the entire process, when the conveying speed of the tape is slower than the speed at which the tape device conveys the substrate, the adhesive portion will drive the anti-sticking roller 141 to rise along the slide rail 144. After the displacement sensor 143 detects it, the conveying speed of the tape will be accelerated; when the conveying speed of the tape is faster than the speed at which the tape device conveys the substrate, the tension of the adhesive portion becomes weaker and the original height of the anti-sticking roller 141 cannot be maintained. Under the action of gravity, the anti-sticking roller 141 descends along the slide rail 144. After the displacement sensor 143 detects it, the conveying speed of the tape will be slowed down.
