DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] Example 1

[0033] Figure 1 A schematic diagram of the structure of the shielding belt cleaning assembly is shown; Figure 1 In the embodiment, the shielding belt cleaning assembly is installed on the travel path of the shielding belt 200 and is used to clean the to-be-cleaned surface 210 of the shielding belt 200 .

[0034] The shielding belt cleaning assembly includes a shell 110, which has at least one entrance 111 and at least one exit 112 for the shielding belt 200 to pass through; at least two groups of transmission roller groups 120 are provided, which are distributed at intervals along the travel path of the shielding belt 200, and each group of transmission roller groups 120 includes two transmission rollers 121, and there is a gap between the two transmission rollers 121 for the shielding belt 200 to pass through.

[0035] The interior of the shell 110 is hollow, and the entrance 111 and the exit 112 are connected to each other. The shielding belt 200 passes through the entrance 111 and exits through the exit 112. There is no limit to the number of entrances 111 and exits 112, and it can be one or more. It only needs to ensure that the shielding belt 200 can pass through one entrance 111 and exit through another exit 112.

[0036] The transmission roller group 120 is used to assist the transmission of the shielding belt 200. In the present embodiment, two transmission roller groups 120 are provided, respectively close to the entrance 111 and the exit 112, so as to avoid interference of the shielding belt 200 with the entrance 111 or the exit 112 when the shielding belt 200 passes through the entrance 111 or the exit 112. In some other embodiments, the number of transmission roller groups 120 is not limited; and after the two transmission rollers 121 in the transmission roller group 120 are installed, the transmission rollers 121 and the shielding belt 200 contact each other and have a certain static friction, so that the two transmission rollers 121 can rotate in the opposite direction during the transmission of the shielding belt 200.

[0037] Continue to see Figure 1 The shielding tape 200 has a surface 210 to be cleaned, and also includes a pay-out roller 130, which is rotatably disposed in the housing 110 to pay out the adhesive tape 150; a take-up roller 140, which is rotatably disposed in the housing 110 to wind up the adhesive tape 150; the adhesive tape 150 is wound on the pay-out roller 130 and the free end is connected to the take-up roller 140, and the adhesive tape 150 has an adhesive surface 151 facing the surface 210 to be cleaned; an upper pressing member 160, which is disposed between the pay-out roller 130 and the take-up roller 140 and squeezes the adhesive tape 150 so that the adhesive surface 151 fits the surface 210 to be cleaned.

[0038] The unwinding roller 130, the take-up roller 140, the adhesive tape 150 and the upper pressing member 160 are all arranged on the side where the surface to be cleaned 210 is located. The unwinding roller 130 and the take-up roller 140 are arranged at an interval, one of which unwinds the adhesive tape 150 and the other rewinds the adhesive tape 150, so that the adhesive tape 150 is unfolded between the unwinding roller 130 and the take-up roller 140, and the adhesive tape 150 has an adhesive surface 151 that can adhere to and clean the surface to be cleaned 210, and at the same time, the upper pressing member 160 squeezes the adhesive tape 150 so that the adhesive surface 151 is attached to the surface to be cleaned 210. The adhesive tape 150 is combined to adhere and clean the surface 210 to be cleaned; and the unwinding roller 130, the taking-up roller 140 and the upper pressing piece 160 are all rotatably arranged in the housing 110, that is, the adhesive tape 150 and the shielding tape 200 are conveyed synchronously, and the linear speeds thereof are the same, so that relative movement on the contact surface between the two can be avoided; when the taking-up roller 140 winds up the adhesive tape 150, the adhesive surface 151 faces the taking-up roller 140; this means that the adhesive surface 151 will be wound up in time after adhering to the surface 210 to be cleaned, so as to avoid the hidden danger of impurities on the adhesive surface 151 falling off for the second time.

[0039] It should be noted that the linear speeds of the adhesive tape 150 and the shielding tape 200 are the same, so that the rotation center of the take-up roller 140 is connected to the output motor. When the output motor is started, the take-up roller 140 can be driven to rotate, thereby winding up the adhesive tape 150. It is only necessary to control the rotation speed of the output motor.

[0040] It should be noted that the driving roller 121, the unwinding roller 130, the taking-up roller 140 and the upper pressing member 160 are all detachably mounted in the housing 110 via a rotating shaft, which is well known to those skilled in the art and the applicant will not elaborate on it in detail.

[0041] Continue to see Figure 1 , and also includes a lower pressing piece 170, based on the upper pressing piece 160 being arranged on the other side of the shielding tape 200, and cooperating with the upper pressing piece 160 to cluster the adhesive tape 150 and the shielding tape 200; the upper pressing piece 160 and the lower pressing piece 170 cooperate to form a clustering area between the two, and when the adhesive tape 150 and the shielding tape 200 pass through the clustering area, the two are pressed and contact each other to clean the surface to be cleaned 210; the upper pressing piece 160 and the lower pressing piece 170 are both rotatably arranged in the shell 110; that is, after the shielding tape 200 and the adhesive tape 150 pass through the clustering area, the upper pressing piece 160 and the lower pressing piece 170 can rotate accordingly and the rotation direction is opposite, so that the circumferential linear movement of the upper pressing piece 160 and the lower pressing piece 170 can be used to offset the transmission of the shielding tape 200 and the adhesive tape 150 to avoid interference with each other.

[0042] Continue to see Figure 1 The lower pressing piece 170 is staggered with the transmission path of the shielding belt 200 to force the shielding belt 200 to form a deformation space 220, and also includes a U-shaped frame 180, which is slidably arranged in the shell 110, and the lower pressing piece 170 is rotatably arranged on the U-shaped frame 180, and a spring 190 is connected between the U-shaped frame 180 and the shell 110; by utilizing the setting of the deformation space 220, a buffer zone is provided for the shielding belt 200 when the transmission is obstructed, and the lower pressing piece 170 can move to the side away from the upper pressing piece 160 to adjust the deformation degree of the deformation space 220, thereby realizing tension adjustment.

[0043] Figure 2 A schematic diagram of the structure between the upper pressing member 160 and the lower pressing member 170 is shown; Figure 2Among them, the upper pressing member 160 and the lower pressing member 170 are both provided with a plurality of arc teeth 161 along the circumferential direction, and a recessed area 162 is formed between two adjacent arc teeth 161, and the arc teeth 161 and the recessed area 162 on the upper pressing member 160 correspond to the arc teeth 161 and the recessed area 162 on the lower pressing member 170 in an interlaced manner to form a wavy space 163 in the clustering area; the upper pressing member 160 and the lower pressing member 170 are both provided with a toothed structure, and the two are meshed with each other, so that the contact position of the two, that is, the clustering area can form a wavy space 163, so that the passing path of the adhesive tape 150 and the shielding tape 200 is more tortuous, thereby improving the cleaning effect of the adhesive surface 151 on the surface to be cleaned 210.

[0044] Example 2

[0045] This embodiment provides a cleaning method for a shielding tape cleaning assembly, and the specific steps are as follows:

[0046] S1, penetrate the shielding tape 200;

[0047] The traction shielding belt 200 enters the housing 110 from the inlet 111, passes through the transmission roller set 120 and the clustering area in sequence, and then exits from the outlet 112;

[0048] S2, inserting the adhesive tape 150;

[0049] The adhesive tape 150 is pulled through the bundling area and connected to the take-up roller 140;

[0050] S3, adhering to the surface to be cleaned 210;

[0051] The shielding tape 200 and the adhesive tape 150 are driven to be transported at the same linear speed, and the adhesive tape 150 and the shielding tape 200 are pressed together by using the bundling area.

[0052] Example 3

[0053] This embodiment provides a vacuum coating system, including the above-mentioned shielding tape cleaning assembly and a vacuum coating machine.

[0054] Among them, the shielding belt cleaning component can be installed in the vacuum coating machine; for example, the Chinese patent with application number "2022228680580" and name "A synchronous belt shielding device for a winding vacuum coating machine" can directly install the shielding belt cleaning component in the vacuum coating machine to cooperate with the cleaning during the continuous coating process.

[0055] The shielding tape cleaning component can also be set separately from the vacuum coating machine, and the two can still form a coating system.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
