Description

Technical Field

[0001] This invention belongs to the field of surface treatment technology for glass fiber resin composite materials, and specifically relates to a laser texturing method for glass fiber reinforced resin composite materials. Background Technology

[0002] Fiberglass resin composites are a relatively mature and widely used composite material, characterized by their light weight, high strength, high modulus, good corrosion resistance, excellent electrical properties, simple processing and molding, and high production efficiency. They are widely used in aerospace, automotive manufacturing, electrical and electronic industries, construction, and pharmaceuticals. Due to their high strength and light weight, fiberglass resin composites can replace traditional steel and aluminum battery packs, contributing to the lightweight manufacturing of new energy vehicles. Laser roughening treatment of the surface of fiberglass resin composites helps to enhance the adhesive strength of the composite material.

[0003] Currently, most methods for roughening fiberglass resin composite panels involve grinding and brushing. This method not only results in low-quality surface roughening but also causes some damage to the panel and generates pollution. Summary of the Invention

[0004] This invention provides a laser texturing method for glass fiber reinforced resin composite materials, which aims to solve the problems of existing surface texturing methods for glass fiber reinforced resin composite material sheets, which not only have low surface texturing quality, but also cause a certain damage rate to the sheet and generate a certain amount of pollution.

[0005] This invention provides a laser texturing method for glass fiber reinforced resin composite materials. The texturing method uses equipment including a feeding unit, a sealed box mounted on the feeding unit, an adsorption loading and unloading unit mounted on the upper part of the sealed box, clamping units mounted on the left and right ends of the sealed box, lateral moving units mounted on the front and rear sides of the sealed box, a longitudinal moving unit mounted within the lateral moving unit, a laser head mounted on the longitudinal moving unit, and a cooling and exhaust gas purification unit mounted on the longitudinal moving unit and the sealed box. The texturing method includes the following steps: S1: Feeding. Place the glass fiber reinforced resin composite material sheet on the feeding unit. The feeding unit transports the glass fiber reinforced resin composite material sheet into the sealed box. After the glass fiber reinforced resin composite material sheet is transported into place, the feeding unit stops operating. S2: Feeding. After the glass fiber reinforced resin composite material sheet is conveyed to the position, the adsorption loading and unloading unit operates. The adsorption loading and unloading unit picks up the glass fiber reinforced resin composite material sheet and lifts it to the clamping unit. S3: Plate fixing. When the glass fiber reinforced resin composite material plate is lifted to the fixed position, the clamping unit operates and the clamping unit stably fixes the glass fiber reinforced resin composite material plate. The adsorption loading and unloading unit releases the plate and resets. S4: Material roughening. After the adsorption loading and unloading unit is reset, the lateral movement unit runs and moves the laser head to the surface of the material. The laser head emits a laser to roughen the surface of the material. When a part of the material is roughened in the lateral direction, the lateral movement unit is reset and the longitudinal movement unit runs. The laser head is adjusted to a position on the material that has not been roughened. Then the longitudinal movement unit stops and the lateral movement unit continues to run, thereby roughening the entire surface of the material. S5: Cooling of the board and purification of exhaust gas. During the roughening process of the board, the cooling and exhaust gas purification unit and the laser head operate simultaneously. The cooling and exhaust gas purification unit cools the surface of the roughened board and purifies the exhaust gas generated during the roughening process through the internal circulating airflow. S6: Unloading. The adsorption loading and unloading unit operates, adsorbs the board, clamps the board by resetting, and places the board on the feeding unit. The feeding unit sends the roughened board away and sends the new board to the sealed box to continue roughening according to the above steps.

[0006] By adopting the above technical solution, the surface of the board is roughened through fully automated production, which greatly improves the roughening efficiency. At the same time, the use of a laser head to roughen the surface of the board not only improves the roughening quality of the board surface, but also reduces the damage rate during the roughening process, and does not produce pollution.

[0007] Furthermore, the feeding unit operates intermittently, with an interval of 1-2 minutes.

[0008] By adopting the above technical solution, the intermittent operation of the feeding unit ensures that the board has sufficient time to roughen in the sealed box.

[0009] Furthermore, the moving speed of the lateral moving unit in step S is 1-2 m / s, and the moving speed of the longitudinal moving unit in step S is 0.5-1 m / s.

[0010] By adopting the above technical solutions, the speed of roughening the board is ensured, thereby guaranteeing the processing efficiency of the board.

[0011] Furthermore, the feeding unit includes a support frame, with rollers rotatably connected to both ends of the support frame. The two rollers are connected by a conveyor belt. Placement frames are evenly distributed on the outer surface of the conveyor belt. The side of the placement frame away from the conveyor belt is rounded. The placement frame is made of rubber. A motor is installed at one end of the support frame, and the motor is connected to one end of one of the rollers.

[0012] By adopting the above technical solution, the roller is driven by a motor to rotate, thereby moving the placement frame on the conveyor belt. This moves the board placed in the placement frame into the sealed box for roughening treatment. One side of the placement frame is rounded to ensure that the moving placement frame can smoothly enter the sealed box.

[0013] Furthermore, the sealed box includes a box body fixed to the upper end of the bracket. Openings are reserved on both the left and right sides of the lower end of the box body. Slide tracks are reserved on both the front and rear sides of the left and right ends inside the box body. A baffle is slidably connected in the slide track. Steel balls are rotatably installed on the front and rear walls of the baffle. The outer wall of the steel balls is in contact with the inner wall of the slide track. The lower end of the baffle is inclined downward from left to right and the lower end of the baffle is set with a rounded corner structure. Two infrared sensors are also fixedly connected to the upper part of the box body, and the distance between the two infrared sensors is equal to the width of the placement frame.

[0014] By adopting the above technical solution, the movable baffle can be pushed open by the moving placement frame, so that the baffle can open and close automatically, making it easy for the placement frame to enter and leave the sealed box.

[0015] Furthermore, the adsorption loading and unloading unit includes a hydraulic cylinder fixed inside the upper part of the box and a negative pressure pump fixed to the upper part of the box. The output end of the hydraulic cylinder is fixedly connected to a cover. The lower end of the cover is connected to multiple suction cups in a ring shape. The suction cups are connected to the negative pressure pump through a hose.

[0016] By adopting the above technical solution, a negative pressure pump creates negative pressure inside the suction cup, thereby sucking up the board. The sucked board can be taken out of or put into the placement frame by the contraction or extension of the hydraulic cylinder, so as to facilitate the loading and unloading of the board.

[0017] Furthermore, the clamping unit includes a second hydraulic cylinder fixed to the left and right walls inside the housing. The output end of the second hydraulic cylinder is fixedly connected to a clamping plate. A rubber sheet is fixedly connected to the wall of the clamping plate away from the second hydraulic cylinder. The rubber sheet has teeth evenly opened on the wall away from the clamping plate, and the teeth are arranged longitudinally.

[0018] By adopting the above technical solution, the hydraulic cylinder can be contracted or extended to clamp and release the sheet metal, which facilitates the roughening or unloading of the sheet metal. At the same time, the rubber sheet and toothed design can ensure the stability of the sheet metal during clamping.

[0019] Furthermore, the lateral movement unit includes an electric slide rail fixed to the rear side wall inside the box and a slide rod fixed to the front side wall inside the box. An electric slider is slidably mounted on the electric slide rail, and a slide sleeve is slidably sleeved on the slide rod. A rectangular frame is fixedly connected between the electric slider and the slide sleeve. The longitudinal moving unit includes an electric slide rail two fixed at the upper and lower ends of the inner side of the rectangular frame. An electric slider two is slidably connected to the electric slide rail two. A concave rod is installed on the electric slider two. One end of the concave rod near the inner side of the box is connected to the laser head.

[0020] By adopting the above technical solution, the laser head can be adjusted by the electric slider one sliding on the electric slide rail one and by the electric slider two sliding on the electric slide rail two, thereby enabling the roughening of various positions on the board.

[0021] Furthermore, multiple laser heads are arranged side by side.

[0022] By adopting the above technical solutions, the texturing efficiency of the board material can be improved.

[0023] Furthermore, the cooling and exhaust gas purification unit includes a manifold fixed to the right side wall inside the housing, a purification box one fixed to the right side wall outside the housing, a purification box two fixed to the upper part of the outer side of the housing, and a branch pipe fixed to the other end of the concave rod. Multiple suction nozzles are evenly connected to the manifold, and the suction nozzles are inclined towards the clamping unit. The lower end of the manifold is connected to the purification box one via a pipe one. Multiple activated carbon filter plates are fitted inside the purification box one. A fan is installed at the upper end of the purification box two. One end of the fan is connected to the upper end of the purification box one via a pipe three, and the other end of the fan is connected to the interior of the purification box two via a pipe two. The lower end of the pipe two extends to the lower end of the interior of the purification box two. Multiple nozzles are connected to the opposite side of the two branch pipes, and the nozzles are angled to the right. Each nozzle corresponds to a laser head. The two branch pipes are connected by a connecting pipe, and the connecting pipe is connected to the purification box two via a flexible hose two.

[0024] By adopting the above technical solution and combining it with a sealed box to form a closed air circulation system, it is possible not only to quickly cool down the roughened board, but also to purify the exhaust gas and eliminate the pollution generated during roughening.

[0025] The beneficial effects of this invention are as follows: This invention uses fully automated production to roughen the surface of the board, which greatly improves the roughening efficiency. At the same time, the use of a laser head to roughen the surface of the board not only improves the roughening quality of the board surface, but also reduces the damage rate during the roughening process, and does not produce pollution. Furthermore, by processing both sides of the board simultaneously, the roughening efficiency of the board is further improved.

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Reference Figure 1-5 This invention proposes a laser texturing method for glass fiber reinforced resin composite materials. The texturing method uses equipment including a feeding unit 1, a sealed box 2 installed on the feeding unit 1, an adsorption loading and unloading unit 3 installed at the upper end of the sealed box 2, clamping units 4 installed at the left and right ends of the sealed box 2, lateral moving units 5 installed on the front and rear sides of the sealed box 2, a longitudinal moving unit 6 installed in the lateral moving unit 5, a laser head 7 installed on the longitudinal moving unit 6, and a cooling and exhaust gas purification unit 8 installed on the longitudinal moving unit 6 and the sealed box 2. By texturing the surface of the board through fully automated production, the texturing efficiency is greatly improved. At the same time, using the laser head 7 to texture the surface of the board not only improves the texturing quality of the board surface but also reduces the damage rate during the texturing process and does not generate pollution.

[0030] Reference Figure 2 The feeding unit 1 includes a support 11, with rollers 12 rotatably connected to both ends of the support 11. The two rollers 12 are connected by a conveyor belt 13. Placement frames 14 are evenly arranged on the outer surface of the conveyor belt 13. The side of the placement frame 14 away from the conveyor belt 13 is rounded. The placement frame 14 is made of rubber. A motor 15 is installed at one end of the support 11. The motor 15 is connected to one end of a roller 12. The motor 15 drives the roller 12 to rotate, thereby moving the placement frame 14 on the conveyor belt 13. This moves the plate placed in the placement frame 14 to the sealed box 2 for roughening treatment. The rounded corner of one side of the placement frame 14 ensures that the moving placement frame 14 can smoothly enter the sealed box 2.

[0031] Reference Figure 2 and Figure 4The sealed box 2 includes a box body 21 fixed to the upper end of the bracket 11. Openings 22 are provided on both the left and right sides of the lower end of the box body 21. Slide tracks 23 are provided on both the front and rear sides of the left and right ends inside the box body 21. A baffle 24 is slidably connected in the slide track 23. Steel balls 25 are rotatably installed on the front and rear walls of the baffle 24. The outer wall of the steel balls 25 is in contact with the inner wall of the slide track 23. The lower end of the baffle 24 is inclined downwards from left to right, ensuring that after the placement frame 14 contacts the inclined surface of the baffle 24, the movement of the placement frame 14 can push the baffle 24 upwards, thereby opening the baffle 24. The baffle 24 is then opened when the placement frame 14 moves away. Behind the baffle 24, it can automatically fall under the weight of the baffle 24. The lower end of the baffle 24 is set with a rounded corner structure, which can reduce the wear between the baffle 24 and the conveyor belt 13. Two infrared sensors 26 are also fixedly connected to the upper end of the box 21. The distance between the two infrared sensors 26 is equal to the width of the placement frame 14. The infrared sensors 26 are used to detect the movement of the board into place, so as to automatically feed, load, and clamp the board. The movable baffle 24 can be pushed open by the movable placement frame 14, so that the baffle 24 can open and close automatically, which facilitates the placement frame 14 to enter and move out of the sealed box 2.

[0032] Reference Figure 2 The adsorption loading and unloading unit 3 includes a hydraulic cylinder 31 fixed inside the upper part of the housing 21 and a negative pressure pump 34 fixed to the upper part of the housing 21. The output end of the hydraulic cylinder 31 is fixedly connected to a cover 32. The lower end of the cover 32 is connected to multiple suction cups 33 in a ring shape. The suction cups 33 and the negative pressure pump 34 are connected through a hose 35. The negative pressure pump 34 creates a negative pressure inside the suction cups 33, thereby adsorbing the board. The adsorbed board can be taken out of or put into the placement frame 14 by the contraction or extension of the hydraulic cylinder 31, so as to facilitate the loading and unloading of the board.

[0033] Reference Figure 2 As shown in Figure 3, the clamping unit 4 includes a second hydraulic cylinder 41 fixed to the left and right walls inside the housing 21. The output end of the second hydraulic cylinder 41 is fixedly connected to a clamping plate 42. A rubber sheet 43 is fixedly connected to the wall of the clamping plate 42 away from the second hydraulic cylinder 41. The rubber sheet 43 has evenly spaced teeth on the wall away from the clamping plate 42. The teeth are arranged longitudinally. By contracting or extending the second hydraulic cylinder 41, the plate can be clamped and released, which facilitates the roughening or unloading of the plate. At the same time, the setting of the rubber sheet 43 and the teeth can ensure the stability of the plate during clamping.

[0034] Reference Figure 2The lateral movement unit 5 includes an electric slide rail 51 fixed to the rear side wall inside the housing 21 and a slide rod 55 fixed to the front side wall inside the housing 21. An electric slider 52 is slidably mounted on the electric slide rail 51, and a slide sleeve 54 is slidably sleeved on the slide rod 55. A rectangular frame 53 is fixedly connected between the electric slider 52 and the slide sleeve 54. The longitudinal movement unit 6 includes an electric slide rail 61 fixed to the upper and lower ends inside the rectangular frame 53. An electric slider 62 is slidably connected to the electric slide rail 61. A concave rod 63 is mounted on the electric slider 62. One end of the concave rod 63 near the inside of the housing 21 is connected to the laser head 7. The laser head 7 can be adjusted by the electric slider 52 sliding on the electric slide rail 51 and by the electric slider 62 sliding on the electric slide rail 61, thereby roughening various positions of the board.

[0035] Reference Figure 2 and Figure 3 Multiple laser heads are arranged side by side to improve the texturing efficiency of the board.

[0036] Reference Figure 2 and Figure 3The cooling and exhaust gas purification unit 8 includes a manifold 81 fixed to the right side wall inside the housing 21, a purification box 1 83 fixed to the right side wall outside the housing 21, a purification box 2 86 fixed to the upper part of the outer side of the housing 21, and a branch pipe 88 fixed to the other end of the concave rod 63. Multiple suction nozzles 82 are evenly connected to the manifold 81, and the suction nozzles 82 are inclined towards the clamping unit 4. The lower end of the manifold 81 and the purification box 1 83 are connected through a pipe 1 84. Multiple suction nozzles are fitted inside the purification box 1 83. An activated carbon filter plate 85 is installed on the upper end of the purification box 86. A fan 813 is installed on the upper end of the purification box 83. One end of the fan 813 is connected to the upper end of the purification box 83 via a pipe 812. The other end of the fan 813 is connected to the interior of the purification box 86 via a pipe 87. The lower end of the pipe 87 extends to the lower end of the interior of the purification box 86. The interior of the purification box 86 contains purification liquid. Multiple nozzles 89 are connected to one side of the two diversion pipes 88. The nozzles 89 are angled to the right. The nozzles 89 are connected to the laser head 7. The two branch pipes 88 are connected by a connecting pipe 810. The connecting pipe 810 is connected to the second purification box 86 by a flexible hose 811. One end of the flexible hose 811 is above the surface of the purification liquid. The fan 813 draws air from the inside of the box 21 through the suction nozzle 82. The gas is adsorbed and filtered by the activated carbon filter plate 85 in the first purification box 83, which also deodorizes and disinfects. The exhaust gas is then sent to the purification chamber through pipe 3 812 and pipe 2 87. In the second purification box 86, the purification liquid in the second purification box 86 purifies the exhaust gas. Then, the purified gas is sent to the split pipe 88 through the second hose 811. The split pipe 88 then distributes the gas to the nozzle 89. The nozzle 89 sprays cold air onto the board to cool the board. At the same time, by combining with the sealed box 2, a closed air circulation system is formed, which can not only quickly cool down the roughened board, but also purify the exhaust gas and eliminate the pollution generated during roughening.

[0037] A hairization method includes the following steps: S1: Feeding. The glass fiber reinforced resin composite material sheet is placed on the feeding unit 1. The feeding unit 1 transports the glass fiber reinforced resin composite material sheet into the sealed box 2. After the glass fiber reinforced resin composite material sheet is transported to the position, the feeding unit 1 stops operating. The feeding unit 1 operates intermittently, with an interval of 1-2 minutes. Through the intermittent operation of the feeding unit 1, sufficient time is ensured for the sheet to be roughened in the sealed box 2. S2: Feeding. After the glass fiber reinforced resin composite material sheet is conveyed to the position, the adsorption and loading unit 3 operates. The adsorption and loading unit 3 picks up the glass fiber reinforced resin composite material sheet and lifts it to the clamping unit 4. S3: Plate fixing. When the glass fiber reinforced resin composite material plate is lifted to the fixed position, the clamping unit 4 operates and the clamping unit 4 stably fixes the glass fiber reinforced resin composite material plate. The adsorption loading and unloading unit 3 releases the plate and resets. S4: Material roughening. After the adsorption and loading unit 3 is reset, the lateral movement unit 5 operates, moving the laser head 7 to the surface of the material. The laser head 7 emits a laser to roughen the surface of the material. When a portion of the material is roughened laterally, the lateral movement unit 5 is reset, and the longitudinal movement unit 6 operates, adjusting the laser head 7 to an unroughened position on the material. Then, the longitudinal movement unit 6 stops, and the lateral movement unit 5 continues to operate, thus roughening the entire surface of the material. In step S4, the moving speed of the lateral movement unit 5 is 1-2 m / s, and the moving speed of the longitudinal movement unit 6 is 0.5-1 m / s to ensure the speed of material roughening and thus guarantee the processing efficiency of the material. S5: Cooling of the board and purification of exhaust gas. During the roughening process of the board, the cooling and exhaust gas purification unit 8 and the laser head 7 operate simultaneously. The cooling and exhaust gas purification unit 8 cools the surface of the roughened board and purifies the exhaust gas generated during the roughening process through the internal circulating airflow. S6: Unloading. The adsorption loading and unloading unit 3 operates, adsorbing the board and clamping unit 4 resets to release the board. The adsorption loading and unloading unit 3 places the board on the feeding unit 1. The feeding unit 1 sends the roughened board away and sends the new board to the sealed box 2 to continue roughening according to the above steps.
