[0002] Most of the car body shell is made of metal materials, such as steel plate, carbon fiber, aluminum, reinforced plastic, etc. The car shells for different purposes and different parts are made of different materials. When the surface of the car plastic shell is laser engraved, a laser engraving device is usually used for laser engraving. Laser engraving generally refers to laser engraving. Laser engraving is based on CNC technology and uses laser as the processing medium. The physical transformation of the processing material, which melts and vaporizes instantly under the irradiation of laser engraving, can enable laser engraving to achieve the purpose of processing.

[0003] In the prior art, when laser engraving is performed on a car taillight, in order to facilitate the laser engraving, the taillight is usually required to be clamped and fixed. Currently, there is no profiling station that can well limit and fix the taillight.

[0004] Therefore, a multi-mode laser engraving profiling station is needed to ensure the placement angle of the taillights and the accuracy of the laser engraving. Summary of the invention

[0012] Further, the top of the second base mold includes a second convex portion and a second concave portion, and the second concave portion includes a second groove;

[0013] The side close to the positioning structure also includes multiple openings that fit the taillights.

[0014] Furthermore, the top of the third base mold includes a third concave portion, a third convex portion is arranged at the bottom of the third concave portion to divide the third concave portion into two equal halves, and a third groove is provided on the side surface of one end of the third convex portion.

[0015] Furthermore, in the positioning structure, a positioning bracket is movably connected to a positioning plate, and the positioning plate is arranged on the top of the tooling structure.

[0016] Furthermore, a cushion layer is provided at the contact end between the positioning plate and the taillight.

[0017] Furthermore, the positioning bracket and the positioning plate are hinged.

[0034] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0035] Embodiment 1:

[0036] A multi-mode laser engraving profiling station, as shown in the figure, includes a tooling structure 100 and a positioning structure 200 on a workbench 1.

[0037] The workbench 1 is connected to a fixing plate 11 at the bottom, connected to a fixing frame 12 at the side, and has a tooling structure 100 and a positioning structure 200 fixed at the top.

[0038] The fixing plate 11 and the fixing frame 12 are fixed to the structure on the laser engraving device. The setting of the fixing plate 11 and the fixing frame 12 can better adapt to laser engraving devices with different functions.

[0039] The tooling structure 100 includes a first base mold 110 , a second base mold 120 and a third base mold 130 which are distributed from the inside to the outside on the workbench 1 .

[0040] In the structural setting of this solution, the bottom surface of the tooling structure 100 is fixed on the workbench 1, the base molds are symmetrically arranged, and the distances between the base molds are the same. The convex and concave parts on the top form a corresponding contour structure of the bottom of the taillight. The height of the first base mold 110 is h1, the height of the second base mold 120 is h2, and the height of the third base mold 130 is h3, where h1>h2>h3.

[0041] In this solution, the top inclination of the first base mold 110 is a1, the top inclination of the second base mold 120 is a2, and the top inclination of the third base mold 130 is a3, wherein a1<a2<a3.

[0042] That is, the first base mold 110 , the second base mold 120 and the third base mold 130 are on the workbench 1 , and the arc-shaped structure formed on the top is adapted to the contact surface of the tail lamp.

[0043] The top of the first base mold 110 fits with the fitting surface of the tail lamp, and includes a first convex portion 111 and a first concave portion 112 . The first concave portion 112 includes a first groove 113 .

[0044] The first recess 112 and the first slot 113 are both rectangular.

[0045] The top of the second base mold 120 is in contact with the surface of the taillight, including a second convex portion 121 and a second concave portion 122, and the second concave portion 122 includes a second slot 123. The side close to the positioning structure 200 also includes a plurality of openings 124 that are in contact with the taillight. In this embodiment, the openings 124 include two strip-shaped openings and a folded angle opening, and a rectangular opening is provided in the folded angle opening.

[0046] The top of the third base mold 130 is in contact with the contact surface of the tail lamp, and includes a third concave portion 131. A third convex portion 132 is arranged at the bottom center of the third concave portion 131, dividing the third concave portion 131 into two grooves. A third slot 133 is formed on one side of the third convex portion 132.

[0047] After the taillight is placed, the bottom fits the first base mold 110, the second base mold 120 and the third base mold 130. Specifically, the protruding part of the taillight fits the concave part of the taillight, and the concave part of the taillight fits the convex part of the base mold to ensure the placement angle of the taillight and the accuracy of laser engraving.

[0048] In order to ensure that the taillights maintain stability during the laser engraving process, a positioning structure 200 is also provided in this solution.

[0049] The positioning structure 200 and the positioning bracket 210 are movably connected to a positioning plate 220 , and the positioning plate 220 is arranged on the top of the tooling structure 100 .

[0050] In the structural setting of this solution, in order to prevent the positioning structure 200 from scratching the taillight during movement, a cushion layer 221 is provided at the contact end between the positioning plate 220 and the taillight. The cushion layer 221 is made of silicone material, and its material properties avoid damage to the taillight.

[0051] The positioning plate 220 is movably connected to the positioning bracket 210, and its connection mode can be that a shaft sleeve is set at the bottom of the positioning plate 220 and sleeved on the positioning bracket 210, or a through hole is opened in the middle and hinged on the positioning bracket 210. In this embodiment, the positioning plate 220 and the positioning bracket 210 are movably connected by hinge.

[0058] The positioning plate 220 on the positioning bracket 210 rotates, and the cushion layer 221 fits the taillight and fixes the taillight.

[0059] Example 2

[0060] The technical feature of this embodiment that is different from that of Embodiment 1 is that a rotating cylinder 230 is fixed on the positioning bracket 210 , and the top of the rotating cylinder 230 is connected to and drives the positioning plate 220 to rotate axially.

[0061] By adding the rotary cylinder 230, the automation of the positioning structure is achieved.

[0062] In summary, the tooling structure provided by the present application is such that after the taillight is placed, the protruding part of the bottom of the taillight fits into the concave part of the taillight, and the concave part of the taillight fits into the convex part of the base mold, thereby ensuring the placement angle of the taillight and the accuracy of the laser engraving;

[0063] The positioning structure provided in the present application ensures that the taillights maintain stability during the laser engraving process through a plurality of base molds, and the material properties of the cushion layer avoid damage to the taillights.
