Description

Technical Field

[0001] The utility model relates to an automatic wire-opening device, in particular to an automatic wire-opening device which is adaptable to wires of different diameters. Background Art

[0002] Due to the small chip size of thermistors and the thin wire diameter, traditional manual soldering processes can easily cause chip position deviation and wire stripping end bending, leading to a series of quality problems such as welding and coating. Automatic wire arranging machines and automatic soldering machines can solve some of the problems of manual operation, but the wire arrays completed by the arranging machine still need to be manually placed on the soldering machine. Insufficient secondary positioning accuracy can easily lead to a high defect rate in the final product.

[0003] Chinese patent CN220138925U discloses a wire stripping and tinning machine. The guide mechanism of the wire stripping and tinning machine is arranged at the front end of the tinning device to allow the wires to enter the tinning device in an orderly manner. The wire positioning mechanism is used to position and fix the wires to avoid interference between the wires. However, the wires are pressed and fixed by pressing the cylinder to drive the pressing block downward, which requires a high output force of the cylinder, increases the cost of use, and is prone to wire sliding, affecting the quality of tinning.

[0029] A mobile platform 2 is fixedly installed on the mobile end of the linear module 1;

[0030] Support frames 3 and a fixed cross plate 4 are respectively fixedly installed on the left and right sides of the mobile platform 2;

[0031] An adjustable guiding and limiting mechanism 6 is arranged on the fixed cross plate 4, and the adjustable guiding and limiting mechanism 6 is used for guiding and separating the wires released from the wire feeding device;

The wire first penetrates into the guiding groove hole 612 and exits from the wire dividing groove 613, realizing the preliminary wire division of multiple wires. The photoelectric switch 614 monitors the wire state in real time and issues an alarm when the wire is missing or broken; Subsequently, the wire passes through between the lower guiding wheel 626 and the upper guiding wheel 627. By adjusting the height of the mounting bracket 623, the distance between the lower guiding wheel 626 and the upper guiding wheel 627 can be changed, so that the guiding grooves 621 of the lower guiding wheel 626 and the upper guiding wheel 627 cooperate to limit and guide wires with different diameters.
