[0023] like Figures 1-3 As shown, one embodiment of this utility model is:

[0024] The shielding tape coating device includes a fixed base 1, a movable frame 2, a separating cylinder 3, a first pressing roller 4, and a second pressing roller 5. The fixed base 1 is horizontally arranged, and the first pressing roller 4 is horizontally rotatably arranged inside the fixed base 1. The movable frame 2 is vertically arranged and slidably connected to the fixed base 1. The second pressing roller 5 is horizontally rotatably arranged at the top inside the movable frame 2. The separating cylinder 3 is arranged at the bottom of the fixed base 1, and its working end is connected to the bottom end of the movable frame 2 to drive the movable frame 2 to move vertically, thereby causing the second pressing roller 5 to move closer to or away from the first pressing roller 4. The first pressing roller 4 has a first cavity inside, and the second pressing roller 5 has a second cavity inside. The sidewall of the first pressing roller 4 has multiple first through holes 41 arranged along its axial direction to connect to the first cavity, and the sidewall of the second pressing roller 5 has multiple second through holes 51 arranged along its axial direction to connect to the second cavity. Both the first cavity and the second cavity are connected to an external negative pressure device.

[0025] During operation, the separating cylinder 3 extends, moving the second pressing roller 5 away from the first pressing roller 4. Both the first pressing roller 4 and the second pressing roller 5 rotate to a predetermined position, placing the end of the shielding tape into the multiple first through holes 41 on the side wall of the first pressing roller 4. The external negative pressure device uses the first cavity to force the multiple first through holes 41 to tighten the end of the shielding tape. The end of the release film is placed into the multiple second through holes 51 on the side wall of the second pressing roller 5. The external negative pressure device uses the second cavity to force the multiple second through holes 51 to tighten the end of the release film. The separating cylinder 3 retracts, bringing the second pressing roller 5 closer to the first pressing roller 4. The first pressing roller 4 and the second pressing roller 5 rotate simultaneously, and their ends automatically align, bonding the release film and the shielding tape together.

[0026] This application uses a separation cylinder 3 to drive the first pressing roller 4 and the second pressing roller 5 to move closer or further apart. By setting multiple first through holes 41 on the first pressing roller 4, the end of the shielding tape is fixed, and by setting multiple second through holes 51 on the second pressing roller 5, the end of the release film is fixed. This prevents the shielding tape and the release film from contacting each other before pressing. By fixing the ends of both separately before pressing, the problem of wrinkles or misalignment due to difficulty in aligning the ends during pressing is avoided, thus improving product quality and production efficiency.

[0027] In one embodiment, such as Figure 1 As shown, the shielding tape coating device also includes a first servo motor 6, which is located on the left side of the fixed base 1. Its working end is connected to the first pressing roller 4, which drives the first pressing roller 4 to rotate and can precisely control the rotation position of the first pressing roller 4.

[0028] In one embodiment, such as Figure 1As shown, the shielding tape coating device also includes a second servo motor 7, which is located on the right side of the movable frame 2. Its working end is connected to the second pressing roller 5. The second servo motor 7 drives the second pressing roller 5 to rotate, and can precisely control the rotation position of the second pressing roller 5.

[0029] In one embodiment, such as Figure 1 , Figure 4 As shown, the shielding tape coating device also includes a film guiding device 8. The film guiding device 8 includes a support frame 81, a first cylinder 82, a movable seat 83, a second cylinder 84, and a film guiding plate 85. The support frame 81 is located at the top of the movable frame 2. The first cylinder 82 is horizontally located on the support frame 81. The movable seat 83 is located at the working end of the first cylinder 82. The second cylinder 84 is vertically located on the movable seat 83. The film guiding plate 85 is located at the working end of the second cylinder 84. The first cylinder 82 and the second cylinder 84 control the horizontal and vertical positions of the film guiding plate 85, respectively. During pressing, the release film passes through the film guiding plate 85 and enters between the first pressing roller 4 and the second pressing roller 5. This further ensures that the release film remains flat before pressing, preventing wrinkles that could affect product quality. Furthermore, when placing the release film and the end of the shielding tape, the film guiding plate 85 can be moved away from the first pressing roller 4 and the second pressing roller 5 to avoid interference.

[0030] In one embodiment, such as Figure 4 As shown, the guiding film device 8 also includes a first guide post 86 and a second guide post 87. The first guide post 86 is disposed on the movable seat 83 and is slidably connected to the support frame 81. The second guide post 87 is disposed on the guiding film plate 85 and is slidably connected to the movable seat 83.

[0031] In this embodiment, there are two first guide pillars 86, which are slidably disposed on the support frames 81 on the left and right sides of the first cylinder 82, respectively. The two first guide pillars 86 are used to maintain the stability of the movable seat 83 during movement. There are two second guide pillars 87, which are slidably disposed on the movable seats 83 on the left and right sides of the second cylinder 84, respectively, and are used to maintain the stability of the guide plate 85 during movement.

[0032] In one embodiment, such as Figure 3 As shown, a first rotary joint 42 is provided at the right end of the first pressing roller 4. The output end of the first rotary joint 42 is connected to the first cavity, and its input end is connected to the external negative pressure device through the first pipeline. The first rotary joint 42 can prevent the pipeline from rotating simultaneously with the first pressing roller 4.

[0033] In one embodiment, such as Figure 3 As shown, a second rotary joint 52 is provided at the left end of the second pressing roller 5. The second rotary joint 52 is connected to the second cavity, and its input end is connected to the external negative pressure device through the second pipeline. The second rotary joint 52 can prevent the pipeline from rotating simultaneously with the second pressing roller 5.

[0034] In one embodiment, such as Figure 2 As shown, a limit post 11 is provided on the fixed base 1, which is used to limit the movement of the movable frame 2.

[0035] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
