Spot welding device for connecting copper sheet with copper-clad ceramic substrates

[0017] The present invention will be further described below in conjunction with the drawings.

[0018] Such as figure 1 As shown, a spot welding device connected with a copper sheet and a copper-clad ceramic substrate includes a drag suction mechanism, an electric welder 15 and a conveying mechanism. The drag suction mechanism includes a first base support 1, a servo motor 2, and a bearing seat 3. Bearings, guide rails 11, rotating shafts, belts 4, connecting plates 5, magnets 6, two bearing seats 3 are symmetrically arranged above the base bracket 1, and the output shaft 9 of the servo motor 2 is mounted on one of the bearing seats 3 through a bearing Inside, the rotating shaft is installed in another bearing housing 3 through a bearing, the output shaft 9 and the rotating shaft are connected by a belt 4, one end of the connecting plate 5 is fixedly connected to the belt 4, and the other end of the connecting plate 5 is installed There are magnets 6. Two guide rails 11 parallel to the belt 4 are provided on the first base support 1, and telescopic support feet 7 are respectively provided on the four corners of the bottom of the first base support 1. There are pulleys 8 on the corners. The length of the pulleys 8 is less than the fully extended length of the supporting feet 7, so that when processing is needed, the supporting feet 7 can be extended for support. When the first base frame 1 needs to be moved, the pulleys can be used 8. It is very convenient to use the two to move.

[0019] The conveying mechanism includes a second base support 10, a guide rail 11 and a sliding carrier 12, and the first base support 1 and the second base support 10 are connected to each other by a plate 16. Two guide rails 11 are arranged in parallel on the second base support 10, and 10 rollers 14 are symmetrically arranged on both sides under the sliding carrier 12, and the rollers 14 can slide back and forth along the guide rail 11. The two guide rails 11 are opposed to the two guide rails 11 on the first base support 1; an electric welding machine 15 capable of welding products placed on the sliding carrier 12 is provided on the end of the second base support 10 close to the first base support 1 .

[0020] In the spot welding equipment for connecting a copper sheet and a copper-clad ceramic substrate of the present invention, the servo motor 1 works to drive the output shaft 9 to rotate, and the output shaft 9 drives the belt 4 to rotate together with the rotating shaft, so that the connecting plate 5 fixed on the belt 4 also follows The magnet 6 can adsorb the copper tube 13, so that it can drive the copper tube 13 to move on the guide rail 11 through the roller 14. Thanks to the servo motor 1, the moving speed of the copper tube 13 can be better controlled, which is convenient for the welding machine 15. Welding multiple sets of copper-clad ceramic substrates and copper sheets has high processing accuracy and improves the processing quality of products. At the same time, because the two guide rails 11 on the second base support 10 are connected to the two guide rails 11 on the first base support 1, this can ensure that the copper tube 13 has a sufficient distance for sliding, which is suitable for processing products of different specifications, and has versatility. Better and easy to use.
