Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 4, the utility model discloses a special tool of laser cutting, including base plate 1 and location lock in the apron 2 of base plate 1 top, a plurality of location caves 11 that are separated mutually by bellying 12 of having arranged in array on the base plate 1, be equipped with a plurality of cutting profile modeling grooves 21 that correspond location cave 11 on the apron 2, location cave 11 comprises a plurality of fretworks and the skeleton texture that links to each other, the fretwork scope of every location cave 11 is greater than the scope of its cutting profile modeling groove 21 that corresponds, be equipped with a plurality of supporting parts 13 that are higher than its bottom surface and are less than bellying 12 in every location cave 11. The positioning cavity 11 has a hollow structure, when the product 3 is placed on the substrate 1, the product will fall into the positioning cavity 11 and will not fall from the hollow position, and the supporting portion 13 of the positioning cavity 11 will support the product 3. After the product 3 is completely coiled, the cover plate 2 is covered, a certain distance is reserved between the cover plate 2 and the upper surface of the product 3, and the processing position of the product 3 can be exposed from the middle of the cutting profiling groove 21. Add man-hour, laser passes 3 wastes materials of product that cutting profile modeling groove 21 downcut, and product 3 still stays in location cave 11, and the waste material can be very easy passes the fretwork position of location cave 11 and falls the below, and the tool is also more convenient to be washd, has saved the cost of installing the steel sheet additional.

As shown in fig. 1 to 3, the substrate 1 is provided with a plurality of first positioning pins 14, and the cover plate 2 is provided with first positioning holes 22 matching the first positioning pins 14. A plurality of second positioning pins 23 are arranged on the cover plate 2, and second positioning holes 15 matched with the second positioning pins 23 are arranged on the base plate 1. The cooperation of locating pin and locating hole is all used for carrying out horizontal location for base plate 1 and apron 2, makes every cutting profile groove 21 can accurately fall on corresponding location cave 11 top, ensures that the position of product 3 is accurate when cutting apart.

As shown in fig. 1 and 3, a plurality of first magnets 16a for attracting the periphery of the substrate 1 are uniformly disposed around the cover plate 2. The base plate 1 is provided with a rib 17 in the middle, and the cover plate 2 is provided with a plurality of second magnets 24b uniformly distributed in the middle for attracting the rib 17. The first magnet 16a is used to attract the cover plate 2 and the edge of the substrate 1, so that the jig is not easily detached during positioning. When the length-width ratio of the jig exceeds 2, one or more ribs 17 are required to increase the absorption position, and the second magnet 24b is used to absorb the cover plate 2 and the base plate 1, so that the middle of the cover plate 2 is prevented from tilting, and the products 3 in the positioning cavities 11 have a small movement space. The first magnet and the second magnet may be provided on the substrate 1.

As shown in fig. 1 and 3, the edge of the substrate 1 is provided with a plurality of lower notches 19 located within the lower projection range of the cover plate 2, and the edge of the cover plate 2 is provided with a plurality of upper notches 25 located within the upper projection range of the substrate 1. Since the peripheries of the base plate 1 and the cover plate 2 are attracted by the magnets, a certain force is required to separate the two. The lower notch 19 and the upper notch 25 are in non-overlapping positions, and when the base plate 1 and the cover plate 2 are separated, an operator can respectively place two fingers of a single hand at the positions of the lower notch 19 and the upper notch 25 to jack the base plate 1 and the cover plate 2. This makes it easier to overcome the attractive force of the magnets.

As shown in fig. 1 to 3, the two-dimensional code mounting hole 16 is provided in the substrate 1, and the two-dimensional code mounting hole 16 is exposed from an upper notch 25 thereof. Two-dimensional code inserts for recording and managing the products 3 are arranged in the two-dimensional code mounting holes 16, and can be detached and replaced, so that the base plate 1 can be reused. Before processing, the laser cutting device can distinguish batches of products 3 according to the two-dimensional code, and detect whether the products 3 which are not completely cut fall off exist and mark the products after cutting is completed for post-processing. Because the two-dimensional code needs to follow the substrate 1 on which the product 3 is placed, but cannot be shielded by the cover plate 2, the position directly corresponding to the upper notch 25 may not increase the processing difficulty.

As shown in fig. 4, the surface of the substrate 1 is plated with a teflon surface 18, and is formed by an electroplating or spraying process. The Teflon material has a smaller friction coefficient, so that the product 3 can conveniently slide into the acupuncture points, and the damage of the substrate 1 to the product 3 is prevented.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
