[0032] To provide a detailed description of the product cutting fixture within this utility model, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] Figures 1 to 4The overall and local schematic structures of the product cutting jig are shown respectively according to the embodiments of the utility model.

[0034] As Figure 1 This is Figure 4 As shown in the drawings, the product cutting jig of the embodiments of the utility model, including metal platform 1 and with metal platform 1 compatible elastic platform 2, wherein, elastic platform 2 is placed on the metal platform 1, and the product to be cut is placed on the elastic platform 2, a first vacuum adsorption hole 11 is arranged on the metal platform 1, a second vacuum adsorption hole 22 corresponding to the first vacuum adsorption hole 11 is arranged on the elastic platform 2, the first vacuum adsorption hole 11 and the second vacuum adsorption hole 22 are communicated with each other in the process of vacuum suction, the elastic adsorption positioning of the product to be cut can be realized, and then the product after adsorption positioning is cut by the external cutting device. The effective positioning of the product can be realized without damaging the appearance of the product, and the product is prevented from shifting during cutting.

[0035] Among them, in order to prevent the elastic platform 2 from deforming in the process of vacuum suction, thereby affecting the cutting quality of the product, a limiting protrusion 12 distributed around the first vacuum adsorption hole 11 can be arranged on the metal platform 1, and a limiting groove 23 corresponding to the position of the limiting protrusion 12 is arranged on the elastic platform 2, when the elastic platform 2 is placed on the metal platform 1, the limiting protrusion 12 is embedded in the limiting groove 23 of the corresponding position, so that the bottom of the elastic platform 2 is fitted with the upper surface of the metal platform 1, thereby effectively preventing the elastic platform 2 from deforming.

[0036] It can be known that the limiting protrusion 12 described above can be a protrusion structure with a long direction, a circle, a special shape consistent with the shape of a single product in the product to be cut or other shapes arranged around a group of vacuum adsorption holes (including the first vacuum adsorption hole 11 and the second vacuum adsorption hole 22), or it can also be arranged as a non-continuous structure, that is, a plurality of protrusion structures spaced from each other can also achieve a certain limiting effect, and a group of vacuum adsorption holes can be understood as at least one vacuum adsorption hole for adsorbing and limiting a single product in the product to be cut, that is, at least one second vacuum adsorption hole 22 is distributed below a single product in the product to be cut, and the first vacuum adsorption hole 11 and the second vacuum adsorption hole 22 are correspondingly distributed.

[0037] Specifically, the shape of the limiting groove 23 is matched with the limiting protrusion 12, through the design of the limiting protrusion 12 and the limiting groove 23, in addition to the positioning effect of the elastic platform 2, the bottom of the elastic platform 2 can also be effectively fitted with the upper surface of the metal platform 1, which can prevent the elastic platform 2 from deforming in the process of vacuum suction, and ensure that the product is accurately cut through.

[0038] As a specific example, the elastic platform 2 can adopt a plate-shaped structure with elasticity such as a rubber platform or a silica gel platform, and the size of the metal platform 1 is not less than the size of the elastic platform 2, so that the elastic platform 2 is effectively supported by the metal platform 1, and the elastic platform 2 provides elastic support and protection for the product to be cut.

[0039] To further realize the relative position accuracy of the elastic platform 2 and the metal platform 1, and the relative position accuracy between the elastic platform 2 and the product to be cut, in the product cutting jig of the utility model, a first positioning member can be arranged on the metal platform 1, and a second positioning member matched with the first positioning member can be arranged on the elastic platform 2, and the positioning of the elastic platform 2 and the metal platform 1 can be realized through the cooperation of the first positioning member and the second positioning member; in other words, through the positioning action of the first positioning member and the second positioning member, the second vacuum suction hole 22 on the elastic platform 2 can be corresponded with the first vacuum suction hole 11 on the metal platform 1, so that the suction function of the product can be effectively realized. The first positioning member and the second positioning member can be arranged as various types of positioning structures, for example, positioning columns, positioning pins, positioning plates, etc.

[0040] Similarly, at least one positioning hole can be arranged on the metal platform 1, and a positioning pin (pin needle) corresponding to the positioning hole can be arranged on the product to be cut, and the positioning pin and the positioning hole cooperate to position the product to be cut and the metal platform 1, so that the single product in the positioned product to be cut corresponds to the position of the second vacuum suction hole 22. It can be known that when the product to be cut is positioned, in addition to the positioning mode with the metal platform 1, the product to be cut can also be positioned with the elastic platform 2, and then the positioning of the product to be cut is realized through the positioning of the elastic platform 2 and the metal platform 1.

[0041] In the product cutting jig of the utility model embodiment, the product to be cut can be understood as a whole version product with a plurality of single products regularly distributed, and the product after suction and positioning is cut by an external cutting device, for example, a cutting knife or a cutting laser, to form a single product. Therefore, a cutting path 21 can also be arranged on the elastic platform 2, and the distribution of the cutting path 21 corresponds to the distribution of the single product in the product to be cut, and the cutting path 21 can be flexibly arranged according to the product and the cutting demand.

[0042] According to the product cutting jig of the utility model, the product to be cut is elastically limited on the metal platform through the elastic platform, and is positioned and adsorbed through the first vacuum adsorption hole on the metal platform and the second vacuum adsorption hole on the elastic platform, and meanwhile, the bottom of the elastic platform is matched with the upper surface of the metal platform through the cooperation of the limiting convex of the metal platform and the limiting groove on the elastic platform, so that the deformation of the elastic platform in the vacuum adsorption process is effectively prevented, the position precision of the product in the cutting process is ensured, and the cutting quality and the cutting efficiency of the product are improved.

[0043] The product cutting jig according to the utility model is described above with reference to the drawings in an exemplary manner. However, those skilled in the art should understand that the product cutting jig of the utility model can be improved in various ways without departing from the content of the utility model. Therefore, the protection scope of the utility model should be determined by the content of the appended claims.
