Technical Field

[0001] The utility model relates to the technical field of electronic carrier tape punching, in particular to a punching device used for electronic carrier tape processing. Background Art

[0002] Electronic carrier tape is mainly used in the electronic component mounting industry. It is used in conjunction with cover tape (upper sealing tape) to carry and store electronic components such as resistors, capacitors, transistors, diodes, etc. in the pockets of the carrier tape, and forms a closed package by sealing the cover tape on top of the carrier tape to protect the electronic components from contamination and damage during transportation. The carrier tape needs to be punched during production.

[0003] After searching, in the prior art, a Chinese patent with patent application number CN202221466781.X discloses a device for accurately positioning laser punching of electronic component carrier tape, including a processing table, a mounting plate is provided above the processing table, a lateral adjustment mechanism for changing the lateral position of the mounting plate is provided at the bottom of the processing table, an electric push rod is provided below the mounting plate, a longitudinal adjustment mechanism for changing the longitudinal position of the electric push rod is provided on the mounting plate, and a fixing block is fixed at the bottom end of the extension rod of the electric push rod. The utility model can change the position of the laser punching head through the mutual cooperation between the lateral adjustment mechanism and the longitudinal adjustment mechanism, so as to facilitate punching of different parts of the carrier tape, and does not require manual movement of the carrier tape, which is more convenient. By setting a connecting component, it is convenient to replace laser punching heads of different diameters, and by setting a limit mechanism, the carrier tape can be fixed to prevent the carrier tape from moving during punching and affecting the punching accuracy, but the following defects still exist:
