[0021] A welding strip shielding device for photovoltaic module production, combined with Figure 1 to Figure 2 As shown, it includes a masking tape container 1 and a connecting guide rod 2, wherein the masking tape container 1 is used to accommodate the masking tape 3, and the end of the masking tape 3 passes through the masking tape container 1; the connecting guide rod 2 is used to connect several masking tape containers 1 side by side, so as to drive several masking tape containers 1 to simultaneously stick several parallelly arranged welding strips.

[0022] The masking tape container 1 is made of a transparent material, so that the remaining amount of the masking tape 3 contained therein can be easily observed, and the masking tape 3 can be replaced in time.

[0023] The masking tape container 1 comprises a first shell and a second shell, which are snap-fitted and detachable, so as to facilitate the replacement of the masking tape 3. Figure 3 As shown, after the first shell and the second shell are buckled, one end forms a flat annular accommodating portion 11, and the other end forms a flat tape outlet 12, wherein the accommodating cavity of the flat annular accommodating portion 11 is annular and is used to accommodate the masking tape 3; the flat tape outlet 12 is connected to the flat annular accommodating portion 11, and the flat tape outlet 12 is used to pass the end of the masking tape 3. When in use, the masking tape 3 is sleeved inside the flat annular accommodating portion 11 and can be rotated inside the flat annular accommodating portion 11 under the pull of the end of the masking tape 3, thereby releasing the masking tape.

[0024] Specifically, the height of the inner end of the flat body belt outlet mouth 12 close to the flat body annular housing 11 is less than the outer diameter of the flat body annular housing 11, and the height of the outer end of the flat body belt outlet mouth 12 away from the flat body annular housing 11 is less than the height of its inner end. The bottom surface of the flat body belt outlet mouth 12 is a plane, and the top surface of the flat body belt outlet mouth 12 is an arc surface that is concave toward the bottom surface and smoothly transitions from its inner end to its outer end.

[0025] After the masking tape container 1 is buckled, the flat body outlet mouth 12 is formed with an outlet at the outer end away from the flat body annular container 11, and the outlet is used to pass the end of the masking tape 3. A guide column 13 is arranged inside the flat body outlet mouth 12, and the guide column 13 is used to guide the end of the masking tape 3.

[0026] The connecting guide rod 2 includes a screw rod 21, on which an external thread is provided, and the outer diameter of the screw rod 21 is adapted to the inner diameter of the flat annular receiving portion 11, and the screw rod 21 is used to pass through the flat annular receiving portion 11, so as to connect a plurality of masking tape containers 1 together. A plurality of annular gaskets 23 are detachably provided on the screw rod 21, and the inner diameters of the annular gaskets 23 are adapted to the outer diameter of the connecting guide rod 2, and the annular gaskets 23 are used to be clamped between adjacent masking tape containers 1, so as to ensure that one masking tape container 1 corresponds to one welding strip by separating adjacent masking tape containers 1 with the annular gaskets 23, and accurately realize that one masking tape container 1 corresponds to one welding strip, which can be achieved by adjusting the number of annular gaskets 23 between adjacent masking tape containers 1. Two locking nuts 24 are also threadedly connected to the screw rod 21 . The two locking nuts 24 are respectively located outside the two outermost masking tape containers 1 . By locking the locking nuts 24 , the masking tape container 1 can be clamped and fixed.

[0027] In order to prevent the locking nut 24 from damaging the masking tape container 1 , a circular gasket 23 is also sandwiched between the locking nut 24 and the masking tape container 1 .

[0028] Sliding connectors 22 are respectively provided at both ends of the connecting guide rod 2. The size of the sliding connector 22 is smaller than the outer diameter of the connecting guide rod 2, so as not to affect the disassembly and assembly of the masking tape container 1, the annular gasket 23 and the locking nut 24 on the connecting guide rod 2. The sliding connector 22 is used to realize the sliding assembly of the connecting guide rod 2, so that the sliding of the connecting guide rod 2 on the assembly part can be realized, and then the masking tape can be automatically attached to the welding strip by driving the masking tape container 1 to move.

[0029] When the utility model is used, the device is first assembled, and the number of masking tape containers 1 on the connecting guide rod 2 is set according to the number of welding strips on the solar cell panel; the number of annular gaskets 23 between adjacent masking tape containers 1 is set according to the spacing of welding strips on the solar cell panel to ensure that one masking tape container 1 corresponds to one welding strip; all masking tape containers 1 and annular gaskets 23 are clamped and fixed by locking nuts 24; then the assembled device is slidably assembled above the conveyor belt through the sliding connector 22 and horizontally arranged along the width direction of the conveyor belt. When the battery cells are welded into a battery string and then come onto this conveyor belt, the transmission belt is stopped, and the end of the masking tape 3 in each masking tape container 1 is adhered to the corresponding end of the welding strip; then the device is slid to simultaneously complete the pasting of the masking tape of each welding strip on the battery string. After the pasting is completed, the masking tape is cut off, the device is reset, and the conveyor belt is started to load and unload materials, and the masking tape of the solder strip on the next battery string is continued. This not only replaces the manual pasting of the masking tape on the solder strip, saving labor costs, but also has high pasting efficiency and accuracy.
