During the laser cutting process, the cutting pattern is generally edited by a computer, the raw material with cutting is placed on the cutting table, and the cutting head is used to cut according to the cutting pattern. However, the laser cutting equipment used for composite materials has the following disadvantages:

[0036] See also Figure 1-Figure 7 As shown, a laser hole-opening device for composite materials of automobile interior with a positioning function is provided, comprising a top cabinet 10 and a cloth plate 40 arranged inside the top cabinet 10 for padding the composite materials to be cut, a hole-opening component for laser hole-opening the composite materials is arranged at the top position inside the top cabinet 10, clamping components are arranged on both sides of the top of the cloth plate 40, a clamping gap is reserved between the clamping components and the top of the cloth plate 40, and driving components are arranged at both ends of the clamping components, and the two clamping components are driven away from each other by the driving components, and the clamping gap is gradually reduced, the two ends of the composite materials are fixed, and the composite materials are pulled toward the two ends to maintain the flat state of the surface;

[0037] The top of the cloth plate 40 is provided with a plurality of collecting holes 410 for collecting the residual materials after cutting, and a plurality of flotation devices 30 are arranged directly below the collecting holes 410. The flotation devices 30 include an air duct 310, and a material sticking column 340 is slidably arranged at the inner end of the air duct 310, and an adhesive layer is arranged at the top of the material sticking column 340. A bottom box 20 is arranged on the outer side of the bottom end of the cloth plate 40, and a collection cabinet 210 is slidably arranged at the top of the bottom box 20. A plurality of bottom holes 211 that are connected to the air duct 310 are arranged at the top of the collection cabinet 210. A blowing assembly is connected between 210 and the bottom end of the air duct 310, and a downward moving assembly is connected between the collection cabinet 210 and the driving assembly. When the driving assembly drives the two clamping assemblies away from each other, the collection cabinet 210 is driven downward by the downward moving assembly, and pressure is applied to the blowing assembly, so that an airflow from top to bottom is formed at the inner end of the air duct 310, and the adhesive column 340 is driven to slide downward to the top of the collection hole 410 corresponding to the protruding position of its adhesive layer, and contact the bottom end of the residual material after cutting, and the viscosity of the adhesive layer is used to drive the residual material to move downward synchronously.

[0038] In the process of laser drilling of the composite material for automobile interior, the composite material raw material with cutting is first placed on the top of the cloth plate 40, so that the two ends of the cloth plate 40 are respectively inserted into the inner ends of the clamping gap at the corresponding positions. Since the collecting holes 410 opened on the top of the cloth plate 40 are set according to the hole opening position of the final product, that is, each collecting hole 410 corresponds to a hole opening position of the composite material raw material to be performed;

[0039] After the composite material raw material placement work is completed, the driving component is started, and the two clamping components are driven to move away from each other by the driving component, and the clamping gap is gradually reduced during the moving away process until the clamping component is clamped at the end position of the composite material raw material. At this time, the driving component continues to drive the two clamping components to move away from each other. At this time, under the action of the clamping component, the two ends of the composite material raw material will be pulled so that it can be laid flat at the top position of the cloth plate 40, thereby straightening the creases on the surface of the composite material raw material due to transportation or accumulation, and reducing the error of the later hole opening;

[0040] While the driving component drives the two clamping components away from each other, the driving component will drive the collection cabinet 210 to move vertically downward along the inner end of the bottom box 20 through the downward moving component, and apply pressure to each blowing component, so that each inner end of the air duct 310 generates an airflow from bottom to top. The power generated by the airflow will overcome the gravity generated by the adhesive column 340 itself, so that the adhesive column 340 moves vertically upward along the inner end of the air duct 310. In this process, the composite material raw material at the corresponding position is processed by the hole opening component. At this time, the residual material formed by the hole opening will adhere to the collection hole 410 aligned with it. The adhesive column 340 at the inner end of the air duct 310 connected to the collecting hole 410 moves to the inner end of the collecting hole 410 under the action of the airflow, and its top will protrude from the top of the collecting hole 410, so that the adhesive layer contacts the bottom end of the residual material and adheres to the bottom end of the residual material by its viscosity. It is worth noting that the hole-opening component performs two steps of hole-opening and vertically moving the adhesive column 340 on the composite material raw material at the same time. When the adhesive layer reaches the bottom end of the residual material, part of the residual material is still not separated from the composite material raw material, so the residual material adheres to the adhesive layer for a period of time before being completely separated from the composite material raw material.

[0041] The clamping assembly is reset under the action of the driving assembly, the collection cabinet 210 moves up, the airflow at the inner end of the air duct 310 disappears, and the sticky column 340 will use its own gravity to drive the residual material adhered to it to move downward, and drive the residual material along the inner end of the collecting hole 410 to separate from the top area of ​​the composite material raw material, exposing the opening position in time, allowing the operator to determine whether there is an opening problem at the first time, so that they can make timely adjustments to avoid the repeated occurrence of the same opening position, which will greatly increase the waste rate of the composite material raw material.

[0042] In addition, the hole opening component includes a transverse gear shaft 110, a longitudinal gear shaft 120 and a pair of laser cutting heads 130. The laser cutting head 130 is arranged on the side of the longitudinal gear shaft 120, and the longitudinal gear shaft 120 drives the laser cutting head 130 to move longitudinally directly above the cloth plate 40. The two ends of the longitudinal gear shaft 120 are respectively connected to the sides of the two laser cutting heads 130, and under the drive of the laser cutting head 130, the longitudinal gear shaft 120 and the laser cutting head 130 are driven to maintain lateral movement directly above the cloth plate 40. In the process of opening holes in the composite material raw material, the laser cutting head 130 is driven by the longitudinal gear shaft 120 to move longitudinally, and during the movement, the laser emitted by the laser cutting head 130 performs laser cutting on the area through which the composite material raw material passes, and then the longitudinal gear shaft 120 and the laser cutting head 130 are driven by the transverse gear shaft 110 to move synchronously laterally, and laser cutting is performed on the moving area until the residual material is completely separated from the position of the composite material raw material to form an opening of a corresponding shape.

[0043] Furthermore, the clamping assembly includes a side plate 430 arranged on the side of the cloth plate 40, and a lower clamping plate 431 for padding the bottom end of the composite material raw material is arranged at the upper end of the side plate 430 close to the cloth plate 40, and an upper clamping plate 432 is arranged at the lower end of the side plate 430 close to the cloth plate 40. A clamping head 433 is hinged at the end position of the upper clamping plate 432, and a torsion spring is arranged at the hinge position of the clamping head 433 and the upper clamping plate 432. Under the action of the torsion spring, the clamping head 433 is maintained in an upward tilted state, and the clamping gap is located between the clamping head 433 and the lower clamping plate 431 in the tilted state. Side openings are opened on both sides of the cloth plate 40, and the driving assembly is connected to the side of the side plate 430, and drives the side plate 430 to maintain translation along the side of the cloth plate 40.

[0044] During specific use, in the process of clamping and fixing the composite material raw material, in the initial padding state, the clamping head 433 is tilted upward under the action of the torsion spring, and cooperates with the lower clamping plate 431 to form a clamping gap. At this time, the composite material raw material is placed above the cloth plate 40, and its two ends are respectively extended to the inner ends of the clamping gap at the corresponding positions, and then the two side plates 430 are driven away from each other by the driving component, so that the lower clamping plate 431 and the clamping head 433 gradually move toward the inner end of the side opening, and under the pressure of the inner wall of the side hole, the clamping head 433 is driven to rotate downward and squeeze the torsion spring. At this time, the clamping head 433 moves downward and reduces the size of the clamping gap until the end of the clamping head 433 contacts the top of the composite material raw material, and uses the downward pressure to clamp and fix the top of the composite material raw material, thereby fixing the composite material raw material and pulling the composite material raw material to keep it in a straight state.

[0045] Furthermore, the driving assembly includes a pair of hydraulic rods 420, the two hydraulic rods 420 are arranged on the sides of the hydraulic rods 420, and the ends of the two hydraulic rods 420 are respectively connected to the ends of the two side plates 430, and the two side plates 430 are driven to move away from or closer to each other under the drive of the hydraulic rods 420.

[0046] Specifically, the downward moving component includes a pair of slide rails 212 and two pairs of rollers 440. The two pairs of rollers 440 are respectively arranged on both sides of the bottom ends of the two side plates 430. The slide rails 212 are arranged at the edge positions on both sides of the top of the collection cabinet 210, and the bottom ends of the rollers 440 are rollingly connected with the top ends of the slide rails 212. Both ends of the slide rails 212 are inclined upward to form a slope. When the two side plates 430 move away from each other, the rollers 440 at their bottom ends will be synchronously driven to roll along the top ends of the slide rails 212 at the corresponding positions and gradually move toward the slope position. In the process of moving along the slope, since the height of the rollers 440 remains unchanged, in order to pass through the slope formed by the slide rails 212, a top-to-bottom pressure will be formed on the slide rails 212, prompting the collection cabinet 210 to move downward along the inner end of the bottom box 20, and the downwardly moved collection cabinet 210 is used to squeeze the air blowing component, generating airflow at the inner end of the air duct 310, thereby blowing the adhesive column 340, so that it can move upward to adhere to the residual material.

[0047] In addition, the blowing assembly includes an air bag 320, and an air outlet aligned with the bottom hole 211 is provided at the top of the air bag 320. The air bag 320 is located at the bottom end of the collection cabinet 210, and during the downward movement of the collection cabinet 210, the air bag 320 is squeezed so that the internal gas is discharged from the air outlet to the inner end of the bottom hole 211 at the aligned position. A plurality of return springs 220 are connected between the bottom end of the collection cabinet 210 and the inner side of the bottom box 20. When the collection cabinet 210 is squeezed and moved downward, pressure is applied to each return spring 220 to cause it to be in a compressed state, and each air bag 320 is squeezed to cause the air bag 320 to deform downward, and its internal space is compressed. The internal gas will be discharged upward through the exhaust port to the inner end of the bottom hole 211 at the corresponding position, and then introduced into the inner end of the air duct 310 at the corresponding position through the bottom hole 211, so as to blow the adhesive column 340. The hydraulic rod 420 drives the side plate 430 to return to its original state, and the top of the collection cabinet 210 loses its extrusion. Each return spring 220 will return to its original state, and use the elastic force generated by it to drive the collection cabinet 210 to return to its original state. Each air bag 320 gradually returns to its original state, and the airflow generated at the inner end of the sticking column 340 gradually disappears, and the sticking column 340 cannot maintain its downward movement. At this time, the sticking column 340 uses its own gravity to drive the adhered waste to move downward together, and when its top reaches the top position of the air duct 310, because the cross-sectional size of the waste is larger than the cross-sectional size of the inner end of the air duct 310, the position around the bottom end of the waste will be blocked by the top of the air duct 310, so that it breaks away from the top position of the sticking column 340, and falls to the upper position of the collection cabinet 210 after breaking away, and is collected and processed by the collection cabinet 210.

[0048] Furthermore, an exhaust pipe 330 is connected between the side of the bottom end of the airbag 320 and one side of the air duct 310. One end of the exhaust pipe 330 is connected to the inner end of the air duct 310, and the other end of the exhaust pipe 330 is connected to the inner end of the airbag 320. A one-way valve is provided at the inner end of the exhaust pipe 330, and is in a closed state during the downward movement of the airbag 320 under pressure, and is in an open state when the airbag 320 is reset. When the airbag 320 is subjected to force, the gas at the inner end of the entire airbag 320 will be discharged into the inner end of the bottom hole 211 along the air outlet, and will be introduced into the inner end of the air duct 310 at the corresponding position through the bottom hole 211, providing a valve for the upward movement of the adhesive column 340. Power, after completing the residual material adhesion work, each air bag 320 is reset, and when resetting, the one-way valve at the inner end of the exhaust pipe 330 is in an open state, and the air bag 320 is reset to provide suction to the inside of the exhaust pipe 330, so that the inside of the air duct 310 is in a negative pressure state. At this time, the top of the adhesive column 340 is connected to the top of the collecting hole 410, and the air duct 310 in the negative pressure state will use the open collecting hole 410 to draw the waste gas generated in the opening process into the inner end of the air duct 310, and introduce it to the inner end of the air bag 320 through the exhaust pipe 330, so as to avoid excessive waste gas accumulation and affect the air environment at the opening position.

[0049] Since the bottom end of the adhesive column 340 will only move upward after being affected by the airflow, if the bottom end of the adhesive column 340 is in a flat state, the airflow will easily diffuse on its bottom surface when in contact, resulting in too low efficiency in starting the adhesive column 340 to move upward. Furthermore, a bottom groove is provided at the bottom end of the adhesive column 340, and the bottom groove has a V-shaped structure. The airflow is gathered by the bottom groove and concentrated at the center of the adhesive column 340, thereby accelerating the starting speed of the adhesive column 340 and ensuring its stability during the upward movement.

[0050] In addition, the adhesive layer is Velcro. When used specifically, since the raw material of the composite material is cloth, during the adhesion process, the adhesive effect between the Velcro and the cloth is used to timely stick the residual material away from the position of the composite material raw material, thereby exposing the opening position, making it convenient for the inspection personnel to observe the opening area.
