Description

technical field [0001] The invention relates to a particle carrier tape forming system and process, in particular to a particle carrier tape forming system and process based on a roller vacuum forming method, and belongs to the technical field of carrier tape manufacturing. Background technique [0002] Carrier tape is a belt-shaped structure product used in the field of electronic packaging to hold SMD components. It has a specific thickness and is equidistantly distributed in the length direction of the box cavity for holding electronic components. , Positioning holes located on one side or both sides of the box cavity for index positioning. It is mainly used in the mounting industry of electronic components. It is used with the cover tape to store electronic components such as resistors, capacitors, transistors, and diodes in the box cavity of the carrier tape, and is formed by sealing the cover tape above the carrier tape. Closed packaging is used to protect electronic ...

Problems solved by technology

[0004] ①The conventional heating step generally uses an extruder to heat and extrude the masterbatch particles. Before production, the masterbatch particles of the extruder need to be baked by a drying system to reduce the water content. The traditional drying method is to use a heater to heat Air, the blower blows hot air into the drying barrel filled with raw material particles. The air outlet of the blower is connected to the exhaust pipe. However, this drying method is easy to bring out debris, dust or foreign impurities in the raw material particles, and blow them into the air in a large area, causing pollution; at the same time, the traditional drying method will directly send hot air with When the water vapor is discharged into the air together, the heating time and the number of heating times at the same time will increase, resulting in an increase in energy consumption;

[0005] ②The masterbatch particles are easy to form carbon deposits in the barrel of the extruder, which needs regular cleaning. When cleaning, it is necessary to discharge the conductive masterbatch particles in the drying barrel, add clean particles, heat and extrude several times, and then put the conductive masterbatch Pour the particles back into the drying barrel. This cleaning method will cause the particles to accumulate at the discharge port, resulting in mixing; at the same time, it will take a long time to repeatedly discharge, feed, dry, and adjust the temperature; therefore, it takes a long time. A feeding mechanism that can save the process of repeated discharging and feeding, and can prevent particles from accumulating at the discharge port;

[0006] ③In the conventional manufacturing process, the carrier tape is wound directly after punching and stripping, and the quality of the carrier tape is not tested. However, during the punching process, the carrier tape sometimes has a sudden change in the hole position, which affects the normal use of customers. , so that customer complaints or even product returns occur, causing huge economic losses to the company; and the surface of the carrier tape is not completely flat, sometimes there will be bumps, which will cause the carrier tape to get stuck at the fast place where the thickness of the receiving material is limited, and the receiving material The pulling force of the cable causes the carrier tape to be deformed or even stuck in the receiving direction, and the carrier tape is scrapped, resulting in a decrease in the production yield and a waste of materials;
