[0032] By using the rotation adjustment component 11, the intermittent lifting component 13, the moving support component 16 and the stamping station component 17 together, the product is processed in multiple stations, making the silver layer distribution of the product more uniform and the bonding strength of the product stronger, avoiding affecting the product quality and saving material costs.

[0033] The processing is monitored by the imaging device of the detector. It can automatically stop the machine immediately when the product is short of material, when the material is used up, when the products are overlapping, or when the needle is broken, so as to stop the loss in time.

[0034] Example 2:

[0035] like Figure 1 and Figure 2 As shown, the automatic welding machine for three-station bimetallic cold heading composite contacts disclosed in Embodiment 2 of this utility model has a structure that is basically the same as that in Embodiment 1. The difference is that the feeding component 3 includes a placement frame 301, which is located on the left side of the protective shell 2. A transmission wheel 302 is provided on the inner side of the placement frame 301, and a guide groove 303 is provided on the inner side of the transmission wheel 302. The cutting component 5 includes a telescopic cylinder 501, which is located on the left side of both the front and rear ends of the protective shell 2. A cutter 502 is provided on the inner side of the telescopic cylinder 501. A detector 6 is installed on the top of the protective shell 2, and a motor 7 is installed on the right side of the protective shell 2.

[0036] The bimetallic wire is transported through the transmission wheel 302 inside the placement frame 301. The guide groove 303 can limit the precise transmission of the wire. After reaching the designated position, it is cut by the cutter 502 driven by the telescopic cylinder 501. Then it is clamped and transported to the bottom mold 4. The detector 6 at the top monitors the processing process. It can automatically stop the machine immediately when the product is short of material, when the material is used up, when the products overlap, or when the needle breaks.

[0037] Example 3:

[0038] like Figure 2 and Figure 3 As shown, the automatic welding machine for three-station bimetallic cold heading composite contacts disclosed in Embodiment 3 of this utility model has a structure that is basically the same as that in Embodiment 2. The difference is that the rotation adjustment component 11 includes a three-station cam 1101, and the three-station cam 1101 is located at the bottom of the front end of the three-station gear set 9. An adjustment groove 1102 is provided inside the three-station cam 1101.

A guide end 1302 is connected to the right side of the rotation support shaft 1301, and a lifting connection end 1303 is connected to the left side of the rotation support shaft 1301.

[0039] The rotating end of motor 7 is connected to a belt, which then drives the turntable 8 to rotate. The turntable 8 drives the internal three-position gear set 9 to rotate. The top gear rod of the three-position gear set 9 is connected to the three-position impact block 10, and the bottom gear rod is connected to the three-position cam 1101. The guide end 1302 is limited inside the adjustment groove 1102. As the three-position cam 1101 rotates, the position of the intermittent lifting component 13 will be continuously adjusted. The adjustment groove 1102 is divided into three sections. During the rotation process, the position of the lifting connection end 1303 will be raised to three different heights.

[0040] Example 4:

[0041] like Figure 4 As shown, the automatic welding machine for three-station bimetallic cold heading composite contacts disclosed in Embodiment 3 of this utility model has a structure that is basically the same as that in Embodiment 3. The difference is that the movable support assembly 16 includes a movable limiting block 1601, and the movable limiting block 1601 is set at the top of the lifting block 15. A reset support rod 1602 is provided on the inner side of the movable limiting block 1601. The stamping station assembly 17 includes a machine head adjusting slider 1701, and the machine head adjusting slider 1701 is connected to the left side of the reset support rod 1602. The left end of the machine head adjusting slider 1701 is provided with station mold 1702, station mold 2 1703 and station mold 3 1704 from bottom to top.

[0042] The lifting of the connecting end 1303 will cause the lifting block 15 to be lifted and adjusted upwards, and slide and limit the movement inside the longitudinal slide plate 14. While rotating and lifting, the three-position impact block 10 will also rotate the extrusion head adjusting slider 1701, allowing the extrusion head adjusting slider 1701 to slide at the top of the moving limit block 1601, so that the first mold 1702, the second mold 1703, and the third mold 1704 of the station will impact and adhere to the bottom mold 4 in sequence, so that the internal contacts are pre-welded and formed for the first time, and then formed for the second time, so that the silver layer is evenly distributed and the bonding strength is higher, and then formed for the third time, so that the product meets the production requirements.

[0043] The specific solution is as follows: The bimetallic wire is transported through the transmission wheel 302 inside the placement frame 301. The guide groove 303 can limit and precisely transport the wire. After reaching the designated position, the wire is cut by the cutter 502 driven by the telescopic cylinder 501. Then, it is clamped and transported to the bottom mold 4. The rotating end of the motor 7 is connected to the belt, which drives the turntable 8 to rotate. The turntable 8 drives the internal three-position gear set 9 to rotate. The top gear rod of the three-position gear set 9 is connected to the three-position impact block 10, and the bottom gear rod is connected to the three-position cam 1101. The guide end 1302 is limited inside the adjustment groove 1102. As the three-position cam 1101 rotates, the position of the intermittent lifting component 13 is continuously adjusted. The adjustment groove 1102 is divided into three sections. During the rotation, the position of the lifting connection end 1303 will be raised. The machine is raised to three different heights. At this time, the lifting of the connecting end 1303 will drive the lifting block 15 to be raised and adjusted, and slide and limit it inside the longitudinal slide plate 14. While rotating and raising, the three-position impact block 10 will also rotate the extrusion head adjusting slider 1701, so that the extrusion head adjusting slider 1701 slides on the top of the moving limit block 1601, and the first mold 1702, the second mold 1703, and the third mold 1704 of the station will hit and adhere to the bottom mold 4 in sequence, so that the internal contacts are pre-welded and formed for the first time, and then formed for the second time, so that the silver layer is evenly distributed and the bonding strength is higher. Then the third product forming is performed to make the product meet the production requirements. The top detection instrument 6 will monitor the processing process and can detect when the product is short of material, when the material is used up, when the product overlaps, or when the needle is broken, and will immediately stop the machine automatically.

Under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this utility model as described above, which are not provided in the details for the sake of brevity.
