[0019] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0020] refer to Figures 1 to 4The embodiment of the present application provides a cam-type cutting device, including a suction nozzle 10, a mounting frame 20, a reduction motor 30, an upper template 40, a lower fixed mold 50 and a lower cutting mold 60 installed on the mounting frame 20, wherein the upper template 40, the lower fixed mold 50 and the lower cutting mold 60 are sequentially distributed from high to low along the same vertical direction, wherein the rotating shaft 31 of the reduction motor 30 extends in the horizontal direction and is fixedly sleeved with a rotating cam 32, and at the same time, the side surface of the rotating cam 32 is provided with an annular limiting groove 301 along the outer circumference, wherein the center of the annular limiting groove 301 is The annular limit groove 301 is not at the same point as the rotating shaft 31. When the rotating shaft 31 of the reduction motor 30 rotates, the annular limit groove 301 will change its position in the vertical plane repeatedly. The bottom of the lower cutting die 60 is vertically connected to a cam shaft 61 that cooperates with the annular limit groove 301, and a guide structure for guiding the lower cutting die 60 in the vertical direction is installed on the mounting frame 20, so that when the rotating cam 32 rotates, the lower cutting die 60 can be driven to move back and forth through the cooperation of the annular limit groove 301 and the cam shaft 61. In addition, the lower fixed The fixed die 50 and the lower cutting die 60 are elastically connected by a spring, and have a certain elastic compression stroke, and the top of the lower cutting die 60 is vertically connected with a cutting knife 62, and the cutting knife 62 extends upward through the lower fixed die 50, so that after the material strip 70 moves to a suitable position between the upper die plate 40 and the lower fixed die 50, the reduction motor 30 can drive the lower cutting die 60, the cutting knife 62 and the lower fixed die 50 to move upward synchronously, wherein the lower fixed die 50 will gradually press and fix the material strip 70 after it abuts against the bottom of the upper die plate 40, and the cutting knife 62 will pass through the lower fixed die 50 and produce The outer side of the product is cut off from the material strip 70, so that the product is separated from the material strip 70. In addition, the suction nozzle 10 is configured to simultaneously absorb the cut product when the cutting knife 62 cuts the material strip 70 between the upper template 40 and the lower fixed template 50. In this way, the suction nozzle 10 can directly put the absorbed product on the plate, avoiding the product from entering the next process in bulk for re-plating, thereby effectively improving work efficiency and not easily damaging the product. Moreover, this method also belongs to the cutting and plating of products with slightly larger volume, which can further reduce costs.

[0021] In one embodiment, the suction nozzle 10 is connected to a robotic arm.

However, with the extension of the use time and other possible situations, the material strip 70 may become loose, which will directly affect the cutting quality and even directly scrap a large number of material strips 70. Therefore, guide plates 21 are symmetrically arranged on both sides of the mounting frame 20, and a guide groove for guiding the material strip 70 is arranged on the top of the guide plate 21, and the guide groove is close to the bottom of the upper template 40. In this way, the material strip 70 can be supported on both sides by the guide groove, ensuring that the material strip 70 at the to-be-cut position can be kept in a horizontal state as much as possible, avoiding the problem of loosening of the material strip 70 to be cut, thereby ensuring the cutting quality.
