The laser cutter 68 drives the laser cutting head 67 to move for laser cutting. After a period of time, the damaged laser cutting head 67 is replaced.

[0060] The lifting shield mechanism 8 includes a push rod mounting plate 60 and a bearing mounting plate 66. Both the push rod mounting plate 60 and the bearing mounting plate 66 are fixed to the lower end of the T-shaped mounting seat 53. A lifting electric push rod 61 is fixed on the push rod mounting plate 60, and a linear bearing 65 is fixed on the bearing mounting plate 66. A lifting slide rod 64 is slidably arranged inside the linear bearing 65. The lower end of the telescopic end of the lifting electric push rod 61 and the lower end of the lifting slide rod 64 are fixed with an annular cover plate 62. Rubber cover blocks 63 are detachably arranged on the four sides of the lower end of the annular cover plate 62.

[0061] The telescopic end of the lifting electric push rod 61 drives the annular cover plate 62 to move longitudinally up and down. The annular cover plate 62 drives the lifting slide rod 64 to slide up and down inside the linear bearing 65, ensuring the stable longitudinal up and down movement of the annular cover plate 62. The annular cover plate 62 drives the rubber cover blocks 63 to move longitudinally up and down, and the longitudinal up and down movement abuts downward on the plate to be cut. The laser cutting head 67 is located in the middle of the upper side of the annular cover plate 62, preventing the waste chips generated by cutting from splashing.

[0062] The working principle of the present invention: The external plate moving mechanism moves the plate to be cut above the placing platform 1. The placing platform 1 is used to support the plate to be cut, that is, the plate is placed on the supporting bristles 15. After the replacement support plate one 13 and the replacement support plate two 14 are used for multiple cuts, the supporting bristles 15 above them will be damaged. After reaching the damaged degree, the replacement support plate one 13 and the replacement support plate two 14 are replaced. The replacement support plate one 13 and the replacement support plate two 14 are narrow in width, which is convenient for replacement and has low cost. After the plate to be cut continues to move below the laser cutting head 67 of the laser cutting assembly 39; The transverse driving mechanism 36 is in transmission cooperation with the cross beam mechanism 3. The position adjusting motor seat 42 can be adjusted in position inside the motor seat installation groove 40 to ensure the stable meshing of the transverse moving gear 41 and the transverse moving rack 30. The output shaft of the transverse moving motor 43 drives the transverse moving gear 41 to rotate. The transverse moving gear 41 meshes with the transverse moving rack 30 and drives the transverse driving mechanism 36 to move horizontally back and forth along the upper slide rail 25 and the side slide rail 34, that is, drives the transverse moving member 35 to move horizontally. The transverse moving member 35 drives the bent connecting plate 27, the vertical driving mechanism 37, the vertical drag chain 5, the lifting shield mechanism 8, the vertical driving mechanism 37, the longitudinal micro driving mechanism 38 and the laser cutting assembly 39 to move horizontally back and forth. The output shaft of the vertical motor 47 drives the vertical lead screw 50 to rotate. A vertical moving seat 51 is arranged on the vertical lead screw 50 in a transmission manner. The vertical moving seat 51 drives the vertical moving vertical plate 52 to move vertically up and down synchronously on the four vertical slide seats 48. The four vertical slide seats 48 slide on the vertical slide rails 49 at the corresponding positions, that is, the vertical moving vertical plate 52 completes the vertical up and down movement and drives the longitudinal micro driving mechanism 38 to move vertically up and down. The output shaft of the micro motor 54 drives the longitudinal lead screw 57 to rotate through the pulley transmission pair 55. A longitudinal moving seat 59 is driven to move on the longitudinal lead screw 57. The longitudinal moving seat 59 drives the connecting plate 70 to move longitudinally left and right. Longitudinal sliding seats 56 are slidably arranged on the longitudinal slide rails 58, that is, the connecting plate 70 completes longitudinal left and right movement, that is, drives the lifting shield mechanism 8 and the laser cutting assembly 39 to move longitudinally left and right; The laser cutter 68 drives the laser cutting head 67 to move for laser cutting. After a period of time, the damaged laser cutting head 67 is replaced; During laser cutting, the lifting shield mechanism 8 can move vertically downward and abut against the upper end of the plate to be cut. The laser cutting assembly 39 cuts the area enclosed by the lifting shield mechanism 8 to avoid the splashing of cutting waste chips. That is, the telescopic end of the lifting electric push rod 61 drives the annular cover plate 62 to move longitudinally up and down. The annular cover plate 62 drives the lifting slide rod 64 to slide up and down inside the linear bearing 65 to ensure the stable longitudinal up and down movement of the annular cover plate 62. The annular cover plate 62 drives the rubber cover block 63 to move longitudinally up and down, and the longitudinal up and down movement abuts downward against the plate to be cut. The laser cutting head 67 is located in the middle of the upper side of the annular cover plate 62 to avoid the splashing of cutting waste chips; When the transverse moving frame member 35 moves horizontally back and forth, the transverse moving frame member 35 is connected to the two sliding seats 24. An accordion shield main body 23 is arranged between the side fixing seat 22 and the rear sliding seat 24 and between the accordion shield sealing plate 28 and the front sliding seat 24. The accordion shield main body 23 can expand and contract stably with the transverse moving frame member 35. The accordion shield main body 23 protects the upper slide rail 25, the transverse rack 30 and the side slide rail 34 to avoid cutting waste chips falling on the upper slide rail 25, the transverse rack 30 and the side slide rail 34, and ensure the stable transmission cooperation between the transverse driving mechanism 36 and the cross beam mechanism 3.

[0063] In summary, through the cooperation of the base assembly 2 and the cross beam mechanism 3, the structural stability is ensured. The placing platform 1 is used to stably support the plate to be cut, and the placing platform 1 facilitates the replacement of components; The upper slide rail 25, the transverse rack 30 and the side slide rail 34 are protected by the accordion shield assembly 4 to avoid cutting waste chips falling on the upper slide rail 25, the transverse rack 30 and the side slide rail 34; Through the cooperation of the vertical drag chain 5, the horizontal drag chain 6 and the wire clamping plate 26, the wire routing is sorted out; The transverse driving mechanism 36, the vertical driving mechanism 37, the longitudinal micro driving mechanism 38 and the laser cutting assembly 39 are protected by the cutting shield 7 to avoid the splashing of cutting waste chips; Through the cooperation of the transverse driving mechanism 36 and the cross beam mechanism 3, and the cooperation with the vertical driving mechanism 37 and the longitudinal micro driving mechanism 38, the horizontal, longitudinal and vertical movement work of the laser cutting assembly 39 is completed to ensure stable laser cutting; The laser cutting head 67 is surrounded by the lifting shield mechanism 8 to avoid the splashing of waste chips generated during cutting and effectively protect the equipment.
