In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0025] Embodiment 1

[0026] Refer to Figures 1-4For the first embodiment of the utility model, the embodiment provides a decorative picture laser engraving production device, can realize the effect that the position of the picture board is prevented from deviating due to inertial force generated when the supporting plate 201 moves in the process of laser engraving, comprising,

[0027] The engraving mechanism 100 comprises a numerical control machine tool 101 and a laser engraving machine 102 which is adaptively installed on the outer surface of the numerical control machine tool 101.

[0028] It should be noted that the numerical control machine tool 101 can control the laser engraving machine 102 and the supporting plate 201 to move through the built-in computer control system, and the laser engraving machine 102 can convert electric energy into laser energy through the built-in laser, generate a high-energy laser beam, and then transmit and focus the laser beam on the surface of the picture board through the laser head. This is prior art, and the present scheme will not be described in detail, and those skilled in the art can clearly understand the working principle.

[0029] The positioning mechanism 200 comprises a supporting plate 201 arranged on one side of the numerical control machine tool 101, a driving assembly 202 arranged on the top of the supporting plate 201, and a clamping assembly 203 arranged on the top of the supporting plate 201.

[0030] It should be noted that through the cooperation of the driving assembly 202 and the clamping assembly 203, the picture board can be clamped and fixed during the laser engraving process, so as to prevent the position from deviating due to inertial force.

[0031] And a limiting mechanism 300 arranged on the top of the supporting plate 201 and cooperating with the driving assembly 202.

[0032] It should be further noted that through the cooperation of the various parts in the limiting mechanism 300, the position of the driving assembly 202 can be effectively prevented from deviating due to external force during the laser engraving process, so as to cause the clamping assembly 203 to release the limiting of the picture board.

[0033] Specifically, the driving assembly 202 comprises a tooth rod 202a arranged above the supporting plate 201, a tooth column 202b engaged with the outer surface of the tooth rod 202a, and a connecting column 202c fixedly connected to the inner surface of the tooth rod 202a. The outer surface of the tooth column 202b is in sliding contact with the top of the supporting plate 201, and the outer surface of the connecting column 202c is fixedly installed on the top of the supporting plate 201 through a bearing.

[0034] The connecting column 202c is used for supporting the tooth rod 202a, and rotating the tooth rod 202a can drive the tooth column 202b to move linearly.

[0035] Further, the driving assembly 202 further comprises a rack 202d fixedly connected to the outer end of the tooth column 202b, a gear 202e engaged with the outer surface of the rack 202d, and a support column 202f fixedly connected to the inner surface of the gear 202e. The outer surface of the rack 202d is in sliding contact with the top of the support plate 201.

[0036] When the tooth column 202b moves linearly, it can drive the rack 202d to move synchronously, so that the rack 202d drives the gear 202e to rotate, and the gear 202e drives the support column 202f to rotate synchronously.

[0037] Preferably, the clamping assembly 203 comprises a first fixed plate 203a fixedly installed on the inner surface of the support plate 201, a stud 203b fixedly connected to the outer end surface of the support column 202f, and an internally threaded block 203c threadedly connected to the outer surface of the stud 203b. The outer surface of the support column 202f is in rotational contact with the inner surface of the first fixed plate 203a.

[0038] The first fixed plate 203a is used to support the support column 202f, so that the support column 202f supports the stud 203b. The two threads of the stud 203b are opposite in direction, and the support column 202f can drive the stud 203b to rotate synchronously when the support column 202f rotates.

[0039] It should be noted that the clamping assembly 203 further comprises a limiting rod 203d fixedly installed on the outer surface of the internally threaded block 203c, a support rod 203e fixedly connected to one side of the limiting rod 203d, a clamping plate 203f fixedly installed on the other end of the support rod 203e, a second fixed plate 203g fixedly connected to the top of the support plate 201 and cooperating with the stud 203b, and a limiting groove 203h opened in the top of the support plate 201. The other end of the stud 203b is fixedly installed on the outer surface of the second fixed plate 203g through a bearing, and the outer surface of the support rod 203e is in sliding contact with the inner wall of the limiting groove 203h.

[0040] The limiting groove 203h limits the two limiting rods 203d, so that the two limiting rods 203d respectively limit the two internally threaded blocks 203c, so that the two internally threaded blocks 203c drive the limiting rod 203d, the support rod 203e and the clamping plate 203f to move towards each other through the rotation of the stud 203b, so that the clamping plate 203f clamps and fixes the drawing board. The second support plate 203g is used to support the other end of the stud 203b, so as to prevent the stud 203b from falling off.

[0041] Further, the limiting mechanism 300 comprises a friction plate 301 fixedly connected to the outer surface of the connecting column 202c, and a rotating column 302 fixedly connected to the outer surface of the support plate 201.

[0042] The connecting column 202c is also used to support the friction plate 301.

[0043] Specifically, the limiting mechanism 300 further comprises friction blocks 303 rotatably connected to the outer surface of the rotating column 302 and used in cooperation with the friction plate 301, and springs 304 fixedly connected to the outer side of the friction blocks 303.

[0044] When the two friction blocks 303 simultaneously contact the outer surface of the friction plate 301, a stronger friction force can be generated, thereby limiting the connecting column 202c.

[0045] In use, the two friction blocks 303 are simultaneously pressed to make the two friction blocks 303 disengage from the outer surface of the friction plate 301 and give a pressure to the springs 304. The rotating tooth rod 202a drives the tooth column 202b to move linearly, the tooth column 202b drives the rack 202d to move synchronously, the rack 202d drives the gear 202e to rotate, the gear 202e drives the supporting column 202f to rotate synchronously with the double-headed stud 203b, the limiting slot 203h limits the two limiting rods 203d, the two limiting rods 203d limit the two internally threaded blocks 203c respectively, the two internally threaded blocks 203c drive the limiting rod 203d, the supporting rod 203e and the clamping plate 203f to move towards each other through the rotation of the double-headed stud 203b, and the clamping plate 203f clamps and fixes the drawing board, thereby preventing the position of the drawing board from deviating due to the inertial force generated when the supporting plate 201 moves. The two friction blocks 303 are loosened, the two friction blocks 303 are reset by the reaction force of the springs 304, the two friction blocks 303 contact the outer surface of the friction plate 301 again, and a stronger friction force is generated, thereby limiting the connecting column 202c. In this way, the position of the connecting column 202c is effectively prevented from rotating in the opposite direction due to external force during laser engraving, thereby releasing the clamping assembly 203 from limiting the drawing board.

[0046] In summary, through the cooperation of the various components in the positioning mechanism 200 and the limiting mechanism 300, the drawing board can be clamped and fixed during laser engraving to prevent the drawing board from deviating due to the inertial force generated when the supporting plate 201 moves, thereby maintaining the stability of the position of the drawing board, ensuring the accuracy and quality of laser engraving, making the entire engraving process more stable and reliable, and achieving the effect of improving the quality of the final product.
