It will be appreciated that the metal strip 110 is fixed in the cavity of the mold 500, and the inner wall of the cavity of the mold 500 can be tightly attached to the upper side and the lower side of the metal strip 110, so as to avoid forming excessive glue on the upper side and the lower side of the metal strip 110, and ensure that the glue layer 400 is formed between the metal strips 110. In addition, in the case of the optical fiber,
for the structure of the mold 500, the mold 500 includes positioning blocks 510, specifically, the positioning blocks 510 are formed in a cavity of the mold 500, a space is formed between the positioning blocks 510, the space is equal to the width of the metal strip 110, and the metal strip 110 is placed in the space during the process of placing the metal strip 110 in the mold 500. It will be appreciated that the metal strip 110 is secured by the positioning block 510 to ensure that the metal strip 110 is properly positioned.
Specifically, the two ends of the positioning block 510 extend to the inner wall of the cavity to completely separate the two adjacent metal strips 110, and the two ends of the metal strips 110 are propped against the inner wall of the cavity, so that the two ends of the metal strips 110 are prevented from forming excessive colloid. It will be appreciated that the positioning block 510 divides the cavity so that a plurality of receiving grooves are formed in the cavity, and the shape of the receiving grooves is adapted to the metal strip 110 so as to avoid forming excessive glue on the metal strip 110.
In order to ensure that the glue layer 400 is formed, the height of the positioning block 510 is lower than the height of the metal strips 110, so that a height difference is formed between the positioning block 510 and the metal strips 110, and the liquid sol fills the space formed by the height difference to form the glue layer 400 between the metal strips 110. It will be appreciated that as shown in fig. 7, there is a certain height difference between the adhesive layer 400 and the metal strip 110 on one side of the reel, and when the reel is bent toward the side with the height difference, the bending effect of the reel is better due to the height difference.
