[0002] Double-sided tape is a roll of adhesive tape made of paper, cloth, or plastic film as the base material, with elastomeric pressure-sensitive adhesive or resin-type pressure-sensitive adhesive evenly coated on the above base material. It consists of three parts: base material, adhesive, and release paper. The tape can stick to things because it has a layer of adhesive coated on its surface. The main components are various polymers. The adhesive can stick to things because bonds are formed between its own molecules and the molecules of the objects to be connected. This bond can firmly bond the molecules together.

[0003] After searching, for example, a Chinese patent document discloses a double-sided tape positioning mechanism [Application No.: CN201821916372.9; Publication No.: CN209440252U]. This double-sided tape positioning mechanism uses a positioning component to position the double-sided tape along the front-to-back direction, and then uses a pressing component to compress the double-sided tape.

[0004] This patent discloses that the double-sided tape is compressed and cut by arranging rolling cutting assemblies on both sides of the positioning assembly. However, symmetrically arranging the rolling cutting assemblies on both sides of the positioning table has high requirements on the working environment, has a large structure, is inconvenient to use, and the two sets of rolling cutting assemblies are easily affected by installation errors, which affects the cutting accuracy of the double-sided tape, thereby affecting the production quality of the double-sided tape.
