As shown in fig. 2 and 3, the cutter assembly 26 is mounted at the lower side of the pressing block 25, the cutter assembly 26 includes a cutter holder 262, a cutter body 261 is mounted at the lower side of the cutter holder 262, and the cutter body 261 is mutually matched with the dicing groove 15 of the dicing seat 14 to dice the substrate 4 therebetween. A receiving groove 252 is formed at the lower side of the pressing block 25, the tool holder 262 is installed through the receiving groove 252, and a certain movable adjustment space is provided between the tool holder 262 and the pressing block 25.
The upper part of the tool apron 262 is rotatably connected in the accommodating groove 252 through the rotating shaft 263, and the tool apron 262 and the tool body 261 at the lower side of the tool apron 262 can realize rotary swinging under the supporting action of the rotating shaft 263. After the upper die 2 and the lower die 1 are pressed together, the tool apron 262 and the tool body 261 can synchronously rotate and swing to cut the base material 4, so that stable and smooth cutting action is realized. Compared with the simple pressing down of the cutter body 261, the cutting action with small-amplitude angle swing can gradually cut friction from one side to form wide-amplitude cutting, so that the smoothness of cutting can be improved; moreover, the cutter body 261 can swing in the cutting process, the deviation inclination angle between the cutter body 261 and the base material 4 can be changed, the cutting inclination angle between the cutter body 261 and the base material 4 is increased instead of the cutting inclination angle between the cutter body 261 and the base material 4, the cutting state is changed by adopting the variable cutting inclination angle, and the smoothness of the cutting action on the base material 4 is improved.
Specifically, as shown in fig. 8, the rotary shaft 263 on the upper side of the tool holder 262 is located at one side of the tool holder 262 and is biased to the left. The other side of the tool holder 262, i.e., the upper portion of the upper side of the tool holder 262, is elastically pulled and supported by a tension spring 264. The knife holder 262 and the replacement are maintained in a stable state by the tension spring 264. An adjusting block 265 is connected to the upper end of the tension spring 264, and the adjusting block 265 penetrates the pressing block 25 upwards and is adjusted with the pressing block 25 in a threaded manner. The upper end position of the tension spring 264 can be adjusted by rotating the adjusting block 265, and the tension spring 264 is driven to act. Furthermore, by adjusting the tension spring 264, the initial inclination angle of the tool apron 262 and the tool body 261 can be adjusted, so that the tool body 261 forms a smooth cutting component to the base material 4 when cutting the base material 4, so as to adapt to the cutting requirements of different base materials 4.
As shown in fig. 3, a linkage assembly is further installed at the outer side of the tool holder 262, and a rotary linkage can be formed between the tool holder 262 and the dicing seat 14 through the linkage assembly, so as to drive the tool body 261 to dice the film material. The linkage assembly can drive the tool apron 262 to rotate and swing in the process of pressing the tool apron 262, so that the middle section of the tool body 261 can swing downwards, and further the substrate 4 is subjected to rotary cutting treatment.
The linkage assembly is arranged on one side of the rotating shaft 263, which is opposite to the tension spring 264, and comprises two groups of pressing frames 266 and pressing blocks 268, wherein the first group of pressing frames 266 and the pressing blocks 268 are arranged on the tool apron 262, and the second group of pressing frames 266 and the pressing blocks 268 are arranged on the cutting seat 14, so that linkage is formed between an upper part and a lower part. The supporting blocks 268 are respectively connected to the corresponding supporting frames 266 through bolts, and the relative heights of the two supporting blocks 268 can be adjusted by rotating the adjusting bolts, so that the positions of the two supporting blocks 268 can be adjusted. Through adjusting the position of supporting piece 268, and then drive two supporting pieces 268 and support the time of pressing the linkage each other to and can drive blade holder 262 and cutter body 261 rotation direction wobbling maximum angle after supporting mutually, and then can carry out the suitability to cutter body 261 to substrate 4 segmentation angle and adjust, in order to adapt to the different segmentation parameters of substrate 4.
By adopting the substrate 4 cutting mechanism, the substrate 4 in the above embodiment can be cut, the substrate 4 is cut, the whole strip-shaped substrate 4 is cut to form a single product, smooth and stable cutting processing of the substrate 4 is facilitated, and smoothness of cutting the substrate 4 is improved.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above examples, and all technical solutions belonging to the concept of the present invention belong to the protection scope of the present invention. It should be noted that modifications and adaptations to the present invention may occur to one skilled in the art without departing from the principles of the present invention and are intended to be within the scope of the present invention.
