Description

Technical Field

[0001] The present invention belongs to the technical field of lamp cover cutting, and specifically relates to a lamp cover cutting device for new energy vehicles. Background Art

[0002] The lamp cover of a new energy vehicle is an important part of the vehicle lighting system, mainly used to protect the internal light source and optimize light transmission. With the development of the lightweight and intelligentization of new energy vehicles, significant innovations have been made in the materials, design, production, processing, and functions of the lamp cover.

[0003] A patent application with the publication number CN210908574U discloses a laser cutting device for the rear lamp cover of an automobile, including a slidable laser cutting device, a support partition, an electrorheological clamping device, a base, a pressing hydraulic machine, and a slidable driving device. The slidable driving device is arranged on the base, and one end of the support partition is arranged on the slidable driving device.

This cutting and fixing method not only increases the complexity of the production process, but also easily prolongs the processing time of the total amount of automobile lamp covers and increases the scrap rate.

Detailed implementation manners

[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0029] As Figures 1 to 6 shown, a cutting device for a new energy vehicle lamp cover according to an embodiment of the present invention includes a machine base 1; a track frame 11 is fixedly connected to the machine base 1; an electric slider 12 is slidably connected to the bottom end of the track frame 11; a laser cutter 13 is fixedly connected to the bottom end of the electric slider 12; a support base 14 is fixedly connected to the machine base 1 and below the track frame 11; a conical cylinder 15 is fixedly connected to the support base 14, the top end of the conical cylinder 15 is provided with an inclined surface, and an anti-slip rubber pad is fixedly connected to the inner wall of the top end of the conical cylinder 15; a pressing component is arranged on the machine base 1, and the pressing component is used to cooperate with the conical cylinder 15 to clamp the new energy vehicle lamp cover; when laser cutting the burrs and residues that appear at the edge of the new energy vehicle lamp cover after demolding, taking the machine base 1 as the main frame of the cutting device for the new energy vehicle lamp cover, first place the curved new energy vehicle lamp cover on the top end of the conical cylinder 15, the inclined surface at the top end of the conical cylinder 15 can fit the outer wall of the new energy vehicle lamp cover, and then cooperate with the anti-slip rubber pad, it can fit the outer wall of the new energy vehicle lamp cover more tightly, the support base 14 supports the lamp cover on the conical cylinder 15, the pressing component presses the center of the top end of the lamp cover, and the pressing component cooperates with the conical cylinder 15 to clamp the lamp cover, so that the four peripheral edges of the lamp cover can be exposed, the electric slider 12 on the track frame 11 drives the laser cutter 13 to automatically adjust the position close to the four peripheral edges of the lamp cover, and laser cut the burrs and residues at the edge of the lamp cover, removing the redundant waste on the new energy vehicle lamp cover at one time, replacing the traditional secondary fixed cutting method, reducing the complexity of the production process, and reducing the generation of defective lamp covers, improving the cutting and processing efficiency of the new energy vehicle lamp cover.

[0030] As Figures 1 to 4 、 Figure 6As shown, a fixing rod 2 is fixedly connected to the support base 14 and at the center of the conical cylinder 15; an adsorption disc 21 is fixedly connected to the top end of the fixing rod 2; when fixedly cutting the lamp cover, the fixing rod 2 is fixed at the top end of the support base 14 to support the adsorption disc 21. First, the automotive lamp cover is placed on the adsorption disc 21 by a mechanical gripper and is located above the conical cylinder 15. As the pressing component presses the lamp cover, the adsorption disc 21 supported on the fixing rod 2 is squeezed to fit more closely to the outer wall of the lamp cover for adsorption until the lamp cover is pressed and fitted on the conical cylinder 15. By the way of the adsorption disc 21 adsorbing the outer wall of the lamp cover, the stability of fixedly laser cutting the lamp cover is improved.

[0031] A plurality of fixing plates 3 are fixedly connected to the conical cylinder 15; a ring plate 31 is fixedly connected to the top end of the fixing plate 3. The ring plate 31 is fixedly connected to the three fixing plates 3 and is arranged corresponding to the adsorption disc 21; when the adsorption disc 21 adsorbs and fixes the outer wall of the new energy vehicle lamp cover, the pressing component presses the lamp cover, causing the lamp cover to squeeze the adsorption disc 21 to deform. The plurality of fixing plates 3 on the conical cylinder 15 support the ring plate 31, making the adsorption disc 21 be pressed and fitted on the ring plate 31. The ring plate 31 squeezes the edge of the adsorption disc 21, ensuring that the edge of the adsorption disc 21 is completely fitted during the extrusion of the center of the adsorption disc 21, and improving the effect of the adsorption disc 21 adsorbing and fixing the outer wall of the lamp cover.

[0032] An air cavity 4 is formed inside the fixing rod 2, and the air cavity 4 can communicate with the center of the adsorption disc 21; a fixing block 41 is fixedly connected to the inner wall of the air cavity 4, and a ventilation hole is formed in the middle of the fixing block 41; two elastic ropes 42 are fixedly connected to the bottom end of the fixing block 41; the bottom end of the elastic rope 42 is fixedly connected to a blocking ball 43. The blocking ball 43 is connected to the fixing block 41 through the two elastic ropes 42, and the blocking ball 43 can block the ventilation hole; when the adsorption disc 21 is squeezed to adsorb the outer wall of the lamp cover, the pressing component continuously squeezes the adsorption disc 21, and the gas inside the adsorption disc 21 is extruded from the air cavity 4 that is connected to the center. The gas inside the adsorption disc 21 passes through the ventilation hole in the center of the fixing block 41. The gas squeezes the blocking ball 43 to separate from the ventilation hole to generate a gap, and the gas is discharged from the gap until the two elastic ropes 42 pull the blocking ball 43 to continue blocking the ventilation hole. By the way of exhausting the air between the adsorption disc 21 and the outer wall of the lamp cover, the stability of the adsorption disc 21 adsorbing and fixing the lamp cover can be improved.

[0033] As Figures 1 to 3As shown, side support blocks 5 are fixedly connected to both sides of the support base 14 respectively; a first roller 51 is rotatably connected to the two side support blocks 5 through a first torsion spring; a first support 52 is fixedly connected to the first roller 51; a first roller 53 is rotatably connected to the first support 52; when supporting the outer wall of the bottom of the lamp shade, the two side support blocks 5 are used to support the rotation of the two first rollers 51 on both sides of the support base 14 respectively. As the lamp shade is pressed and fitted onto the conical cylinder 15, the first rollers 53 on both sides of the support base 14 are respectively fitted onto the outer walls of both sides of the curved lamp shade. The first support 52 cooperates with the first torsion spring to support the first roller 53. With the elastic support of the first roller 53, it can play an auxiliary supporting role for both sides of curved lamp shades of different models, and cooperate with the limit plate 54 to limit the maximum rotation amplitude of the first support 52, improving the effect of auxiliary support for the lamp shade.

[0034] As Figure 1 , Figure 2 , Figure 5 and Figure 6 shown, a second roller 6 is rotatably connected to the first support 52 through a second torsion spring; second supports 61 are fixedly connected to both sides of the second roller 6 respectively; a sliding plate 62 is slidably connected to the second supports 61, and a limit hole is provided on the sliding plate 62; a second roller 63 is rotatably connected to the top end of the sliding plate 62; a bolt 64 is threadedly connected to the second support 61, and the bolt 64 passes through the limit hole of the sliding plate 62; when the first rollers 53 support both sides of the curved lamp shade, the second roller 6 cooperates with the second torsion spring to rotate on the first support 52 to support the two second supports 61. The second rollers 63 on the two sliding plates 62 are respectively extended and fitted onto the outer wall of the bottom of the curved lamp shade, and the position of the sliding plate 62 is adaptively fixed by using the bolt 64 to pass through the limit hole, improving the effect of supporting curved lamp shades of different models.

[0035] The pressing and covering assembly includes an electric cylinder 7, a connecting rod 71 and a pressing head 72; the electric cylinder 7 is fixedly connected to the top end of the machine base 1; the connecting rod 71 is fixedly connected to the output end of the electric cylinder 7; the pressing head 72 is fixedly connected to the bottom end of the connecting rod 71, and the pressing head 72 is located at the center position of the conical cylinder 15; when pressing and fixing the lamp shade, the output end of the electric cylinder 7 is used to drive the connecting rod 71 to slide downwards. The pressing head 72 at the bottom of the connecting rod 71 is fitted onto the lamp shade until the pressing head 72 presses the lamp shade and fits it onto the conical cylinder 15, thereby realizing the clamping of the lamp shade from top to bottom and ensuring the stability during the cutting of the new energy vehicle lamp shade.

[0036] The shape of the pressing head 72 is set to be semi-spherical, and the bottom surface of the pressing head 72 is set to be flat; when the pressing head 72 fits against the outer wall of the new energy vehicle lamp cover, the bottom plane of the pressing head 72 presses against the center of the curved lamp cover, ensuring the stability of the clamping of the lamp cover by the pressing head 72 and the conical cylinder 15. Relying on the semi-spherical shape of the pressing head 72 can adapt to the curved surface of the lamp cover and improve the adaptability to clamping different curved lamp covers.

[0037] A fixing frame 8 is fixedly connected to the connecting rod 71; both inner walls of the fixing frame 8 are slidably connected with sliding rods 81; a connecting plate 82 is fixedly connected to the bottom end of the sliding rod 81; a pressing wheel 83 is rotatably connected to the connecting plate 82; an elastic member 84 is sleeved on the sliding rod 81, and the elastic member 84 is located between the fixing frame 8 and the sliding rod 81; when clamping and fixing the top of the lamp cover, the two pressing wheels 83 first press against the outer wall of the top of the lamp cover as the output end of the electric cylinder 7 extends downward. As the output end of the electric cylinder 7 continues to extend downward, the sliding rod 81 on the connecting plate 82 slides upward on the inner wall of the fixing frame 8, and the elastic member 84 is pulled and stressed until the pressing head 72 presses against the outer wall of the top of the lamp cover and clamps the lamp cover with the conical cylinder 15. The elastic pressing of the pressing wheel 83 can adapt to different models of curved lamp covers, thereby realizing the stable laser cutting of the whole lamp cover and improving the fixing effect of the lamp cover.

[0038] As Figures 1 to 6 shown, a fixing box 9 is fixedly connected to the outer wall of the electric cylinder 7; an extrusion plate 91 is slidably connected to the inner wall of the fixing box 9, and one end of the extrusion plate 91 away from the fixing box 9 is fixedly connected to the connecting rod 71; a one-way valve 93 is fixedly connected to the fixing rod 2; a trachea 92 is fixedly connected between the fixing box 9 and the one-way valve 93; when the laser cutting of the new energy vehicle lamp cover is completed, as the output end of the electric cylinder 7 drives the connecting rod 71 to retract, the extrusion plate 91 squeezes the gas inside the fixing box 9 into the trachea 92. The gas is sent to the air cavity 4 communicated with the one-way valve 93 through the trachea 92. Due to the setting of the one-way valve 93, the gas inside the trachea 92 can enter the air cavity 4 but cannot return. After the gas enters the air cavity 4, it enters the adsorption disc 21. After the gas enters the adsorption disc 21, the vacuum inside it is destroyed, facilitating the detachment of the lamp cover from the adsorption disc 21, thus facilitating the picking up of the cut finished product.

[0039] Working process: When laser cutting the burrs and residues on the edge of a new energy vehicle lamp cover after demoulding, the machine base 1 serves as the main frame of the new energy vehicle lamp cover cutting equipment. First, place the curved new energy vehicle lamp cover on the top of the conical cylinder 15. The inclined surface at the top of the conical cylinder 15 can fit the outer wall of the new energy vehicle lamp cover. Together with the anti-slip rubber pad, it can fit the outer wall of the new energy vehicle lamp cover more tightly. The support base 14 supports the lamp cover on the conical cylinder 15, and the pressing component presses the center of the top of the lamp cover. Moreover, the pressing component cooperates with the conical cylinder 15 to clamp the lamp cover, so that the four peripheral edges of the lamp cover can be exposed. The electric slider 12 on the track frame 11 drives the laser cutter 13 to automatically adjust the position close to the four peripheral edges of the lamp cover, and laser cuts the burrs and residues on the edge of the lamp cover, removing the excess waste on the new energy vehicle lamp cover at one time. It replaces the traditional secondary fixed cutting method, reduces the complexity of the production process, reduces the generation of defective lamp covers, and improves the cutting and processing efficiency of the new energy vehicle lamp cover; When fixedly cutting the lamp cover, the fixed rod 2 is fixed on the top of the support base 14 to support the suction cup 21. First, place the vehicle lamp cover on the suction cup 21 through the mechanical claw and be located above the conical cylinder 15. As the pressing component presses the lamp cover, the suction cup 21 supported by the fixed rod 2 is squeezed to fit the outer wall of the lamp cover more closely for adsorption until the lamp cover is pressed and fitted on the conical cylinder 15. By the way of the suction cup 21 adsorbing the outer wall of the lamp cover, the stability of the fixed laser cutting of the lamp cover is improved; When the suction cup 21 adsorbs and fixes the outer wall of the new energy vehicle lamp cover, use the pressing component to press the lamp cover, so that the lamp cover squeezes the suction cup 21 to deform. The multiple fixing plates 3 on the conical cylinder 15 support the annular plate 31, so that the suction cup 21 is pressed and fitted on the annular plate 31. The annular plate 31 squeezes the edge of the suction cup 21, so that during the extrusion of the center of the suction cup 21, it is ensured that the edge of the suction cup 21 is completely fitted, improving the adsorption and fixing effect of the suction cup 21 on the outer wall of the lamp cover;

[0040] When the suction cup 21 is squeezed to adsorb the outer wall of the lamp cover, the pressing component continuously squeezes the suction cup 21, and the gas inside the suction cup 21 is extruded from the air cavity 4 with central connection. The gas inside the suction cup 21 passes through the air permeable holes in the center of the fixed block 41, and the gas squeezes the plugging ball 43 to break away from the air permeable hole to generate a gap, and the gas is discharged from the gap until the two elastic pull ropes 42 pull the plugging ball 43 to continue to block the air permeable hole. By the way of removing the air between the suction cup 21 and the outer wall of the lamp cover, the stability of the suction cup 21 adsorbing and fixing the lamp cover can be improved;

[0041] When supporting the outer wall of the bottom of the lamp shade, two side support blocks 5 are used to support the rotation of two first rollers 51 on both sides of the support seat 14 respectively. As the lamp shade is pressed and fitted onto the conical cylinder 15, the first rollers 53 on both sides of the support seat 14 are respectively fitted onto the outer walls of both sides of the curved lamp shade. The first bracket 52 cooperates with the first torsion spring to support the first roller 53. With the elastic support of the first roller 53, it can play an auxiliary supporting role on both sides of curved lamp shades of different models, and cooperate with the limit plate 54 to limit the maximum rotation amplitude of the first bracket 52, improving the effect of auxiliary support for the lamp shade; when the first roller 53 supports both sides of the curved lamp shade, the second roller 6 is used to cooperate with the second torsion spring to rotate and support two second brackets 61 on the first bracket 52. The second rollers 63 on the two sliding plates 62 are respectively extended and fitted onto the outer wall of the bottom of the curved lamp shade, and bolts 64 are used to penetrate the limit holes to adaptively fix the positions of the sliding plates 62, improving the supporting effect for curved lamp shades of different models;

[0042] When pressing and fixing the lamp shade, the output end of the electric cylinder 7 drives the connecting rod 71 to slide down. The pressing head 72 at the bottom of the connecting rod 71 is fitted onto the lamp shade until the pressing head 72 presses the lamp shade and fits it onto the conical cylinder 15, thereby realizing the clamping of the lamp shade from top to bottom and ensuring the stability during the cutting of the new energy vehicle lamp shade; when the pressing head 72 fits the outer wall of the new energy vehicle lamp shade, the bottom plane of the pressing head 72 presses at the center of the curved lamp shade to ensure the stability of the clamping of the pressing head 72 and the conical cylinder 15 on the lamp shade. Relying on the semi-spherical shape of the pressing head 72, it can adapt to the curved surface of the lamp shade, improving the adaptability to different curved lamp shades during clamping; when clamping and fixing the top of the lamp shade, two pressing wheels 83 first press onto the outer wall of the top of the lamp shade as the output end of the electric cylinder 7 extends downward. As the output end of the electric cylinder 7 continues to extend downward, the sliding rod 81 on the connecting plate 82 slides upward on the inner wall of the fixed frame 8, and the elastic member 84 is pulled and stressed until the pressing head 72 presses on the outer wall of the top of the lamp shade and clamps the lamp shade with the conical cylinder 15. The elastic pressing of the pressing wheels 83 can adapt to different models of curved lamp shades, thereby realizing the stable laser cutting of the whole lamp shade and improving the effect of fixing the lamp shade;

[0043] When the laser cutting of the new energy vehicle lamp shade is completed, as the output end of the electric cylinder 7 drives the connecting rod 71 to retract, the pressing plate 91 squeezes the gas inside the fixed box 9 into the trachea 92. The gas is sent through the trachea 92 to the air cavity 4 connected to the one-way valve 93. Due to the setting of the one-way valve 93, the gas inside the trachea 92 can enter the air cavity 4 but cannot return. After the gas enters the air cavity 4, it enters the suction disc 21. After the gas enters the suction disc 21, the vacuum inside it is destroyed, facilitating the detachment of the lamp shade from the suction disc 21, thus facilitating the picking up of the cut finished product.
