Description of the embodiments

The structure and other aspects of the present utility model of a parallel wire thermistor chip element soldering robot will be described in further detail below by way of specific embodiments and with reference to the accompanying drawings.

The automatic welding line for the parallel thermistor chip elements comprises a wire foot forming device for forming the end parts of parallel wires 10 into a V-shaped structure. As shown in fig. 1 and 2, the stitch forming device includes a bracket 1, a driving device 2, and left and right clamps 3 and 4, the driving device 2, the left and right clamps 3 and 4 being mounted on the bracket 1. The left clamp 3 and the right clamp 4 are rotatably mounted on the bracket 1 through a rotation shaft 5. The driving device 2 can apply a force to the left clamp 3 and the right clamp 4 to rotate the left clamp 3 and the right clamp 4 about the rotation shaft 5.

As shown in fig. 3 and 4, the left clamp 3 has a first end 32 and a second end 33, and the right clamp 4 also has a first end 42 and a second end 43. The first ends 31, 41 of the left and right clamps 3, 4 close or separate from each other as the left and right clamps 3, 4 are rotated about the rotation axis 5. The second end 34 of the left clamp 3 and the second end 43 of the right clamp 4 are respectively provided with a third inclined surface 431, and a V-shaped opening is formed between the two third inclined surfaces 431.

In one embodiment, the driving device 2 of the stitch forming device comprises a roller 21, and the roller 21 can extend into the V-shaped opening formed by the third inclined surface 431 under the driving of the driving device 2, so that the left clamp 3 and the right clamp 4 rotate around the rotating shaft 5, at this time, the second end 33 and the second end 43 are separated, and the first end 32 and the first end 42 are closed. The second end 33 of the left clamp 3 and the second end 43 of the right clamp 4 are connected by the elastic member 6. In a specific embodiment, the elastic member 6 is, for example, a tension spring. When the roller 21 is withdrawn from the V-shaped opening between the third inclined surfaces 431 by the driving device 2, the left clamp 3 and the right clamp 4 rotate in opposite directions about the rotation shaft 5, and at this time the second ends 33 and 43 are closed and the first ends 32 and 42 are separated.

As shown in fig. 5, the stitch forming device further includes a fixing block 7, and the fixing block 7 is located between the first end 32 of the left clamp 3 and the first end 42 of the right clamp 4. The fixed block 7 is provided with two second inclined surfaces 71 having a V-shape. Accordingly, the first end 32 of the left clamp 3 is provided with a first inclined surface 321, and the first end 42 of the right clamp 4 is provided with a first inclined surface 421, the first inclined surfaces 321, 421 being respectively parallel to the two second inclined surfaces 71 of the V-shape, so as to apply pressure to the parallel wire ends located therebetween when the first end 32 and the first end 42 are closed.

When the stitch forming device works, the driving device 2 drives the roller 21 to move downwards, and the second end 33 of the left clamp 3 and the second end 43 of the right clamp 4 are close to each other under the action of the tension spring 6. As the left clamp 3 and the right clamp 4 are rotated about the rotation shaft 5, respectively, the first ends 32, 42 of the left clamp 3 and the right clamp 4 are separated. The parallel wires 10, the ends of which have been separated, are moved down such that the fixing blocks 7 are located between the ends of the parallel wires 10. The driving device 2 drives the roller 21 to move upwards, and as the roller 21 continuously extends into the V-shaped opening between the third inclined surfaces 431, the second end 33 of the left clamp 3 and the second end 43 of the right clamp 4 are separated, the left clamp 3 and the right clamp 4 rotate around the rotating shaft 5 in the directions opposite to the directions, and the first end 32 of the left clamp 3 and the first end 42 of the right clamp 4 are closed. The end of the parallel wire 10 made of metal is pressed to form a V-shaped structure due to the presence of the first and second inclined surfaces. After the end portion of the parallel wire is formed, the driving device 2 drives the roller 21 to move downwards again, the second end 33 of the left clamp 3 and the second end 43 of the right clamp 4 approach each other under the action of the tension spring 6, and the first end 32 of the left clamp 3 and the first end 42 of the right clamp 4 are separated. The doubling 10 is moved horizontally and laterally (out of the page) to withdraw the doubling 10. Through the mode, the parallel wire end part can be formed into a V-shaped structure in an automatic mode so as to clamp the chip conveniently.

The above embodiments are merely for illustrating the spirit and scope of the present utility model and are not intended to limit the scope of the present utility model. Modifications, equivalent substitutions and other improvements to the embodiments described above which are obvious to those skilled in the art are also within the spirit of the present utility model.
