Detailed Description
A large-size carrier tape forming die is shown in figures 1 to 9 and comprises a circular body 1, wherein a circular right gasket 2 is connected to one side of the circular body 1, a circular left gasket 3 is arranged on one side, away from the circular body 1, of the circular right gasket 2, a plurality of circular forming pieces 4 are arranged between the circular right gasket 2 and the circular left gasket 3, a circular middle gasket 5 is arranged between adjacent circular forming pieces 4, and a circular die cover plate 6 is arranged on one side, away from the circular right gasket 2, of the circular left gasket 3; a plurality of pocket grooves 7 are arranged on the outer edge surface of the circular forming piece 4 at intervals, a plurality of air suction grooves 8 which are in one-to-one correspondence with the pocket grooves 7 are arranged on the side wall surface of the circular forming piece 4, a plurality of first air suction holes 9 which are in one-to-one correspondence with the air suction grooves 8 are also arranged on the side surface of the circular forming piece 4, a gap 10 is formed between the side wall of each air suction groove 8 and the body of the circular forming piece 4, the top end of the gap 10 is communicated with the corresponding pocket groove 7, and the bottom end of the gap 10 is communicated with the first air suction holes 9; a plurality of second air suction holes 11 which are in one-to-one correspondence with the first air suction holes 9 on the circular forming sheet 4 are respectively arranged on the side wall of the circular body 1, the side wall of the circular right gasket 2 and the side wall of the circular middle gasket 5. Nine circular forming segments 4 are used in the embodiment, nine carrier tapes are produced simultaneously, and the production efficiency is high.
The size of the gap 10 is 0.07mm to 0.13mm, such as 0.07mm, 0.08 mm, 0.09 mm, 0.1mm, 0.11mm, 0.12 mm or 0.13mm, preferably 0.1mm, so as to ensure the stability of the thickness of the carrier tape during the plastic suction molding and not to block the suction groove because the gap is too small.
The diameters of the circular body 1, the circular right gasket 2, the circular middle gasket 5, the circular forming piece 4 and the circular left gasket 3 are all 246mm, and the number of the pocket grooves 7 is 192. The carrier tape forming die within the diameter range and within the number range of the pocket grooves 7 can avoid increasing the difficulty of die manufacturing, effectively ensure the efficiency of carrier tape forming and reduce the deformation of the carrier tape during demoulding.
The diameter of the circle surrounded by the plurality of first air suction holes 9 on the circular molding sheet 4, the diameter of the circle surrounded by the plurality of second air suction holes 11 on the side wall of the circular body 1, the diameter of the circle surrounded by the plurality of second air suction holes 11 on the side wall of the circular right gasket 2, and the diameter of the circle surrounded by the plurality of second air suction holes 11 on the side wall of the circular middle gasket 5 are all 225 mm. The length of the air suction grooves 8 is 4 mm-10 mm, such as 4mm, 5mm, 6mm, 7mm, 8 mm, 9 mm or 10mm, preferably 8.25mm, to avoid the air suction grooves 8 of the circular molding sheet 4 from being blocked. The outer edges of the circular right gasket 2, the circular middle gasket 5 and the circular left gasket 3 are 0.1 mm-0.6 mm higher than the bottom of the pocket groove 7 on the circular forming sheet 4, such as 0.1mm, 0.2mm, 0.3 mm, 0.4 mm, 0.5 mm or 0.6mm, preferably 0.2mm, because when the carrier tape is used, the upper surface of the carrier tape needs to be sealed with the cover tape, so that the semiconductor or electronic component carrier tape is packaged in the pocket groove 7, the sealing tension and the stability of the tension of the carrier tape and the cover tape are very high, therefore, the space between the outer edges of the circular right gasket 2, the circular middle gasket 5 and the circular left gasket 3 and the bottom of the pocket groove 7 on the circular forming sheet 4 can affect the sealing quality, the space is small, the wave of the corresponding position of the carrier tape can be large, so that the sealing is bad, the space is large, when the carrier tape is wound into a roll, the bottom of the pocket on the upper layer can be pressed on the position, and can even crush the cover tape and electronic components.
