[0022] The utility model provides a 3D patch cutting template set. The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings to make it easier to understand and grasp.

[0023] Example 1

[0024] refer to Figure 1-Figure 6 , a 3D patch cutting template set, comprising:

[0025] A cutting base 1, wherein the cutting base 1 has a receiving space, and a through hole 2 communicating with the receiving space is provided on the cutting base 1;

[0026] A cutting template 7 is provided on a cutting base 1. The cutting template 7 is provided with a cutting opening 8 adapted to the 3D patch 5. The cutting opening 8 is provided corresponding to the through hole 2. A height difference is formed between the cutting template 7 and the accommodating space of the cutting base 1 so that the 3D molding rough piece 6 can sink into the cutting opening 8 and the accommodating space of the cutting template 7, and the 3D molding rough piece 6 is cut along the cutting opening 8 to form the finished shape of the 3D patch 5.

[0027] In this embodiment, the cutting base 1 is a shell with an opening at one end, and the shell is provided with a through hole 2 on the opposite side of the opening.

[0028] The size of the through hole 2 is larger than the size of the cutting opening 8 .

[0029] The 3D patch cutting template group provided in this embodiment changes the original 3D patch molding rough piece that is inverted on the molding template and is visually aligned and processed by personnel to: first fix the cutting template 7 on the cutting base 1, and use the height difference formed between the cutting base 1 and the cutting template 7 to sink the 3D molding rough piece 6 into the cutting template 7, and then cut it after self-alignment, which solves the problem of inconsistent shapes of the finished products of the cut 3D patch 5.

[0030] In this embodiment, a first positioning hole 3 is provided on the side of the through hole 2 of the shell, and a second positioning hole 9 is provided on the cutting template 7 . The first positioning hole 3 and the second positioning hole 9 are provided correspondingly and are connected by a spring pin 4 .

[0031] Specifically, there are four first positioning holes 3 arranged along the circumference of the shell; four second positioning holes 9 are arranged circumferentially on the cutting template 7, and the four first positioning holes 3 correspond to the four second positioning holes 9 one by one and are respectively connected by a spring pin 4.

[0032] The four first positioning holes 3 are respectively arranged at the four ends of a rectangle, and at the same time, the four second positioning holes 9 are arranged corresponding to the four first positioning holes 3 and are located at the four ends of the same rectangle.

[0033] Since the 3D patch 5 has multiple models and the sizes of each model of 3D patch are different, in order to ensure the versatility of the cutting base 1, the debugging of the laser cutting origin position is simplified when making the cutting template 7. The X-axis and Y-axis positions on one side of the multiple groups of cutting templates 7 are aligned. As long as the position of the cutting base 1 is determined and the laser cutting origins of all the cutting templates 7 are consistent, the cutting operation can be performed without re-adjusting the cutting origin position when switching product specifications.

[0034] In this embodiment, the 3D patch 5 includes an L-type 3D patch and an R-type 3D patch with the same top view shape but opposite protrusion directions. Since the four second positioning holes 9 are arranged corresponding to the four first positioning holes 3 and are at the four end points of the same rectangle, the cutting template 7 used for cutting the L-type 3D patch can be used for cutting the R-type 3D patch after being flipped 180 degrees.

[0035] This embodiment utilizes the flipping of the long side of the cutting template to solve the product switching between the L-type 3D patch and the R-type 3D patch, thereby halving the processing quantity of the cutting template and reducing the cost.

[0036] The above fully describes the technical solution of the present invention. It should be noted that the specific implementation of the present invention is not limited to the above description. All technical solutions formed by ordinary technicians in the field using equivalent or equivalent transformations in structure, method or function based on the spirit of the present invention fall within the protection scope of the present invention.
