For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0035] like Figure 1-3 As shown in the embodiment, a laser engraving fixing tool for a car luminous mark includes:

[0036] The sign supporting plate 1 comprises a sign supporting surface 11 inclined relative to a horizontal plane and a back surface opposite to the sign supporting surface 11 along a thickness direction of the sign supporting plate 1;

[0037] A positioning component 2 is disposed on the sign supporting surface 11, and the positioning component 2 is configured to cooperate with the sign concave and convex parts along the thickness direction of the sign supporting plate 1;

[0038] The angle adjustment component 3 is connected to the sign supporting plate 1 and extends in a direction away from the positioning component 2 .

[0039] A sign supporting plate 1 is provided to support and carry the sign; a positioning component 2 is provided on the sign supporting surface 11 to limit the movement of the sign within the plane where the sign supporting surface 11 is located; the sign supporting plate 1 and the positioning component 2 cooperate to solve the problems of poor stability, low repeatability and reproducibility of the laser engraving fixing tooling for the automobile luminous sign.

[0040] The inclination angle of the sign support plate 1 is adjusted by the angle adjustment component 3 to improve the accuracy and enable the laser beam focus of the laser engraving machine above the sign to move along the complete luminous area trajectory without blind spots, thereby solving the problem of poor conformity of the luminous area trajectory.

[0041] The positioning components 2 may include multiple ones and be dispersedly arranged on the sign supporting surface 11. The movement of the sign is further restricted by multi-point positioning, thereby improving the stability of the automobile luminous sign laser engraving fixing device.

[0042] The positioning component 2 cooperates with the concave and convex parts of the sign. The positioning component 2 is raised on the sign supporting surface 11 or recessed in the sign supporting surface 11. The concave and convex parts of the positioning component 2 are arranged to fit the structure of the sign.

[0043] like Figure 1-3 As shown, in another preferred embodiment, the sign supporting plate 1 has a first side portion 12 and a second side portion 13 relative to each other, and the first side portion 12 and the second side portion 13 are respectively connected to the base 4 through the angle adjustment component 3, or one of the first side portion 12 and the second side portion 13 is connected to the base 4 through the angle adjustment component 3, and the other is detachably connected to the base 4.

[0044] In this embodiment, at least one of the two opposite side edges of the sign supporting plate 1 is connected to the base 4 via the angle adjustment assembly 3. The two opposite side edges of the sign supporting plate 1 are the first side edge 12 and the second side edge 13.

[0045] In this embodiment, both the angle adjustment component 3 and the base 4 are connected to the two opposite sides or one of the two sides of the sign supporting plate 1. Compared with the angle adjustment component 3 being set in the middle position of the sign supporting plate 1, this setting can better ensure the stability of the sign supporting plate 1, and thus ensure the stability of the car cursor laser engraving fixing tooling.

[0046] When one of the first side edge 12 and the second side edge 13 of the sign supporting plate 1 is connected to the base 4 through the angle adjustment component 3, the inclination angle of the sign supporting plate 1 relative to the horizontal plane is adjusted by adjusting the height of the angle adjustment component 3, and thus the position of the sign is adjusted; when the first side edge 12 and the second side edge 13 of the sign supporting plate 1 are respectively connected to the base 4 through the angle adjustment component 3, the inclination angle of the sign supporting plate 1 relative to the horizontal plane is adjusted by the height difference between the two angle adjustment components 3, and thus the position of the sign is adjusted.

[0047] like Figure 1-3 As shown, in another preferred embodiment, the angle adjustment component 3 is a support plate 31 , one end of the support plate 31 is detachably fixedly connected to the sign supporting plate 1 , and the other end is disposed on the base 4 .

[0048] The angle adjustment component 3 is set as a support plate 31 to ensure that the contact surface between the angle adjustment component 3 and the sign supporting plate 1 is maximized, thereby increasing the contact area and improving the stability of the tooling.

[0049] In this embodiment, the angle adjustment assembly 3 is fixedly connected to the sign supporting plate 1 to further improve the stability of the tooling.

[0050] like Figure 1-3 As shown, in another preferred embodiment, the positioning assembly 2 includes a first protrusion 21 and a second protrusion 22, and the second protrusion 22 is circumferentially distributed along the first protrusion 21 and forms a limiting groove 23 with the first protrusion 21; the first protrusion 21 and / or the second protrusion 22 are provided with a sign positioning pin 24, and the limiting groove 23 and the sign positioning pin 24 along the thickness direction of the sign supporting plate 1 are configured to cooperate with the sign convex and concave.

[0051] Optionally, the positioning component 2 is a positioning pin, or a positioning boss.

[0052] In this embodiment, the first protrusion 21, the second protrusion 22 and the limiting groove 23 therebetween are used to limit the overall position of the sign; and the sign positioning pin 24 is provided to match the positioning pin hole on the sign and is sleeved in the positioning pin hole of the sign to limit the partial position of the sign. Optionally, a plurality of sign positioning pins 24 are provided.

[0053] like Figure 1-3 As shown, in another preferred embodiment, it also includes a clamping assembly 5, which is fixedly arranged on the sign supporting plate 1. The clamping assembly 5 includes a clamping member 51 located above the sign supporting surface 11, and the sign abutting surface 511 of the clamping member 51 is arranged opposite to the sign supporting surface 11.

[0054] The pressing component 5 is used to press the sign against the sign supporting surface 11 along the thickness direction of the sign supporting plate 1 to achieve the pressing and fixing of the sign. The pressing component 5 limits the sign along the thickness direction of the sign supporting plate 1 to improve the stability of the tooling, the stability and high precision of the laser engraving process.

[0055] Optionally, at least three clamping assemblies 5 are provided and dispersedly arranged to improve the stability of the sign.

[0056] In this embodiment, the pressing assembly 5 is detachably disposed on the sign supporting plate 1 .

[0057] like Figure 1-3 As shown, in another preferred embodiment, the clamping assembly 5 also includes a telescopic member 52; one end of the telescopic member 52 along the telescopic direction is fixedly connected to the sign supporting plate 1, and the other end is rotatably connected to the clamping member 51; the clamping member 51 moves along the axial direction of the telescopic member 52.

[0058] The clamping assembly 5 increases or decreases the distance between the clamping member 51 and the sign along the thickness direction of the sign supporting plate 1 through the telescopic member 52, thereby achieving the compression and relaxation of the sign. Optionally, the telescopic member 52 is fixedly connected to the sign supporting plate 1 by bolts.

[0059] The pressing member 51 is rotatably connected to the telescopic member 52 so that the pressing member 51 is always located above the side of the sign, which is convenient for placing and taking the sign. When the sign needs to be pressed, the pressing member 51 is rotated to the top of the sign.

[0060] Optionally, the telescopic member 52 is a gas cylinder, an oil cylinder, etc.

[0061] like Figure 1-3 As shown, in another preferred embodiment, the sign abutting surface 511 is provided with a flexible abutting portion 5111 .

[0062] By providing the flexible abutting portion 5111, it is prevented that the components in direct contact with the nameplate are too hard to cause scratches on the surface of the nameplate, thereby affecting the quality of the product.

[0063] In this embodiment, the angle adjustment component 3 is set to a fixed height, and the working steps of this embodiment are as follows:

[0064] Step 1: First, place the sign in the first raised portion 21, the second raised portion 22 and the limiting groove 23 therebetween according to the concave-convex structure of the sign, and limit the sign as a whole; then, fix the clamping assembly 5 on the sign supporting plate 1 along the circumference of the sign; finally, rotate the clamping member 51 of the clamping assembly 5 axially along the telescopic member 52 to just above the sign, tighten the telescopic member 52, and tighten it until there is a gap between the clamping member 51 and the sign. The size of the gap allows the sign to rotate circumferentially along the limiting groove 23 to adjust the angle of the sign, but will not cause the sign to escape from the limiting groove 23.

[0065] Step 2: First, preliminarily fix the position between the first side edge 12 and the second side edge 13 of the sign supporting plate 1 and the base 4 or the angle adjustment component 3, but do not lock the space with angle change; then, adjust the height of the angle adjustment component 3 connected to the other side edge of the sign supporting plate, and at the same time, rotate the sign circumferentially along the limit groove 23 to adjust the angle of the sign until the laser of the laser engraving machine can run completely along the trajectory of the luminous area at one time without the problem of poor segmented fit; finally, lock the position between the sign supporting plate 1, the angle adjustment component 3 and the base 4.

[0066] Step 3: The sign is further limited by the sign positioning pin 24, and the pressing assembly 5 is tightened at the same time, so that the pressing member 51 completely abuts the sign against the sign supporting plate 1. At this time, the sign can be laser engraved.

[0067] like Figure 1 , Figure 4-5As shown, in another preferred embodiment, the angle adjustment component 3 includes a support plate 31, and the support plate 31 includes a main body 311 and an angle adjustment plate 312; the main body 311 has a top end 3111 and a bottom end 3112 opposite to each other along a first direction, the top end 3111 is rotatably connected to the sign supporting plate 1 around a rotating shaft extending in a third direction, and the bottom end 3112 is connected to the base 4; the end surface of the top end 3111 is provided with a concave adjustment groove 3113, and the main body 311 is provided with an adjustment port 3114 intersecting and communicating with the adjustment groove 3113; at least one angle adjustment plate 312 is arranged in the adjustment groove 3113 and moves along the first direction, the angle adjustment plate 312 has a plate top 3121 abutting against the sign supporting plate 1, and the angle adjustment plate 312 is detachably fixedly connected to the main body 311; the first direction is a direction perpendicular to the base surface 41 of the base 4, the second direction is a plate thickness direction of the support plate 31, and the third direction is a direction perpendicular to both the first direction and the second direction.

[0068] By setting a rotational connection between the main body 311 of the support plate 31 and the sign supporting plate 1, the angle between the sign supporting plate 1 and the support plate 31 is adjusted, thereby adjusting the angle of the sign supporting plate 1 relative to the horizontal plane. An angle adjustment plate 312 is set, and after the relative positions of the support plate 31 and the sign supporting plate 1 are determined, the top 3121 of the angle adjustment plate 312 is abutted against the sign supporting plate 1, thereby overcoming the problem of a gap at the contact point between the two in the rotational connection, filling the gap, increasing the contact surface, and improving the stability of the tooling.

[0069] In this embodiment, a plurality of angle adjustment plates 312 are arranged along the second direction.

[0071] The limiting waist hole 313 , the locking bolt 32 and the locking nut 33 are used to achieve the limiting locking between the angle adjustment plate 312 and the support plate 31 .

[0072] The limiting waist hole 313 is arranged through two surfaces of the support plate 31 and the angle adjustment plate 312 that are opposite to each other along the second direction. The limiting waist hole 313 extends along the first direction, and the locking bolt 32 moves in the limiting waist hole 313 along the first direction.

[0074] The height of the angle adjustment plate 312 is adjusted by the heightening member 34, and then the angle between the angle adjustment plate 312 and the sign supporting plate 1 is adjusted, so as to finally realize the position of the sign.

[0075] Optionally, a plurality of height-raising members 34 are provided.

[0076] The height-increasing member 34 is detachably fixedly connected to the main body 311 , and the height-increasing member 34 is detachably fixedly connected to the base 4 .

[0077] In this embodiment, the working steps based on the embodiment in which the angle adjustment assembly 3 or the support plate 31 includes a plurality of angle adjustment plates 312 are as follows:

[0078] Step 1: Initially, one of the first side edge 12 and the second side edge 13 of the sign support plate 1 is connected to the base 4 or the support plate 31, and there is at least a linear connection between the two during the tooling adjustment process; the other is rotatably connected to the support plate 31.

[0080] Step 3: Adjust the position of each angle adjustment plate 312 from the adjustment port 3114 so that the top 3121 of the angle adjustment plate 312 abuts against the sign supporting plate 1; and lock the angle adjustment plate 312 with the locking bolt 32 and the locking nut 33. At this point, the sign can be laser engraved.
