Description

Technical Field

[0001] This invention relates to the field of new energy vehicle technology, and in particular to a lightweight new energy vehicle anti-collision beam and its manufacturing process and equipment. Background Technology

[0002] Anti-collision beams can be considered the first line of defense for passive safety in automobiles. In low-speed collisions, they can reduce vehicle repair costs, and in medium- and high-speed collisions, they can protect the personal safety of occupants to a certain extent. In the production process of anti-collision beams, aluminum materials are used in the design of anti-collision beams to reduce the overall weight and achieve a lightweight effect.

[0003] When designing crash beams, to facilitate the disassembly of the damaged crash beam and the usable energy-absorbing box in case of future damage, bolts or riveting are typically used to connect the crash beam and the energy-absorbing box. However, when using fasteners to fix the crash beam and energy-absorbing box, the strength of the fasteners at the connection point needs to be strengthened. Furthermore, during the production of aluminum crash beams, the aluminum profiles need to be manually lifted onto a bending machine, where they are then bent to meet the structural design requirements of the crash beam. This process involves loading and unloading... During the process, the aluminum profiles need to be moved manually, which is very inconvenient. After bending the aluminum profiles, the bending degree also needs to be checked by personnel, resulting in low processing efficiency. Furthermore, after bending the aluminum profiles, the bent aluminum profiles need to be transported manually to the processing area for drilling and assembly with the energy-absorbing boxes. Even when aluminum materials are used to produce the crash beams, the crash beams still have a certain weight and length, making it inconvenient for manual handling. The overall processing efficiency needs to be further improved. Summary of the Invention

The second springs are sleeved with the inner extension shafts, and one end of the second spring is fixed to the detection contact shaft.

[0019] A manufacturing process for a lightweight anti-collision beam for new energy vehicles includes the following steps:

[0020] S1: Place the aluminum profile to be bent on the loading rack. The movable plate descends to the loading rack, and the aluminum profile is clamped between the first side clamp and the second side clamp. Then the movable plate rises to the processing area. After the movable plate rises to the position, the aluminum profile is pushed to the position between the two mounting frame plates. The roller rotates to push the aluminum profile to be processed towards the bending machine side. While the aluminum profile is being pushed between the rollers, the electric cylinder drives the mounting cylinder to move back and forth towards the surface of the aluminum profile. During the movement of the mounting cylinder, the abutment can contact the surface of the aluminum profile. The aluminum profile squeezes the abutment and triggers the first switch. At the same time that the first switch is triggered, the distance sensor starts to perform a distance measurement. The distance sensor detects the distance to the surface of the aluminum profile to be processed by uniformly dotting the surface.

[0021] S2: When the aluminum profile enters the bending machine and is in place, the bending machine performs bending operations on both ends of the aluminum profile. After one end of the aluminum profile is bent, the bent aluminum profile on one side is pushed again between the upper and lower rollers. At this time, it is detected that the bent end of the aluminum profile has entered between the rollers on both sides. At this time, the electric cylinder drives the connecting frame to push towards the aluminum profile. The two rollers rotate away from the aluminum profile and contact the surface of the aluminum profile. The first switch is triggered, and the distance sensor detects the distance of the aluminum profile. During detection, an intermittent uniform dot detection operation is adopted. When the bent end of the aluminum profile moves between the rollers on both sides, the front end of the aluminum profile moves between the two fixed clamps. The fixed clamps can support the anti-collision beam body after bending from the unloading side. Simultaneously, when the bent end of the aluminum profile moves between the rollers on both sides, an intermittent dot arc detection operation is continuously performed on the end.

[0022] S3: After the inspection is completed, the roller will continue to convey the bent anti-collision beam body to the flipping mechanism side. At the same time, the first side clamp and the second side clamp located on the feeding side will clamp the bent anti-collision beam body. Simultaneously, after clamping the anti-collision beam body, the first side clamp and the second side clamp will move the anti-collision beam body away from the bending machine side by an appropriate distance. Then the first side clamp and the second side clamp will release the bent anti-collision beam body. At the same time as the release, the fixed clamp will clamp the anti-collision beam body. After clamping in place, the movable shaft will rotate to drive the bent anti-collision beam body to flip.

[0023] S4: If the curvature of the anti-collision beam body does not meet the standard, the movable shaft will rotate the anti-collision beam body 90° clockwise to the corresponding non-conforming material rack side. The fixed clamp will be released at any time. The non-conforming anti-collision beam body will be placed on the non-conforming material rack for centralized storage for subsequent processing. If the curvature of the anti-collision beam body meets the standard, the movable shaft will rotate the anti-collision beam body 180° clockwise to the corresponding assembly mechanism side, preparing for the assembly operation of the anti-collision beam body and the energy-absorbing box. At this time, the feeding side position can carry out the next feeding and bending inspection operation of aluminum profiles.

[0024] S5: Before assembling the crash beam body and energy-absorbing box, the support frame is docked and assembled with the energy-absorbing box. An external robotic arm places the energy-absorbing box inside the energy-absorbing box positioning sleeve, and the inner clamping plate clamps and fixes the energy-absorbing box. After the crash beam body is flipped to the corresponding assembly mechanism side, the two lower brackets on both sides rotate to the position where the detection contact shaft faces the crash beam body side. The lower brackets move to the middle position, and the detection contact shaft can contact the surface of the crash beam body. At the same time as the contact, the second switch is triggered, and simultaneously, the dot counter starts to count dots. The result of the dot counter reflects the distance that the lower brackets on both sides have moved on the surface of the crash beam body. The target distance is set in advance by the operator. When the lower bracket moves to the target distance... When the distance sensor detects that the distance between the two lower brackets is equal to the distance between the energy-absorbing boxes on both sides of the anti-collision beam body under standard conditions, it indicates that the energy-absorbing box on the positioning sleeve is aligned. The lower bracket moves and resets. At this time, the fixed clamping plate drives the anti-collision beam body to move towards the energy-absorbing box side for docking. After docking, the drilling machine drills holes in the anti-collision beam body and the energy-absorbing box. After drilling, the machine switches to the riveting machine to perform riveting operations at the drilled holes in the anti-collision beam body and the energy-absorbing box. After riveting, the anti-collision beam body and the energy-absorbing box are assembled. The movable rotating shaft drives the assembled anti-collision beam body and the energy-absorbing box to rotate 90° clockwise. The external robotic arm removes the assembled anti-collision beam body and the energy-absorbing box, and the processing is completed.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] This invention features a support frame, a riveted anti-collision beam body, and an energy-absorbing box, facilitating subsequent disassembly and maintenance of the anti-collision beam body and the energy-absorbing box. The support frame is positioned between the anti-collision beam body and the energy-absorbing box. During assembly, the support frame is manually inserted into the energy-absorbing box for initial positioning. In the subsequent assembly of the energy-absorbing box and the anti-collision beam body, after accurate positioning of the anti-collision beam body and the energy-absorbing box, they are assembled. During assembly, drilling is performed simultaneously on the anti-collision beam body and the energy-absorbing box, eliminating the need for separate drilling and alignment. To address the issue of hole misalignment, the support frame can provide support between the crash beam body and the energy-absorbing box during drilling, ensuring drilling stability. Simultaneously, during the riveting process of the crash beam body and the energy-absorbing box, the support frame can be re-fixed at the connection point between them. This ensures the support frame is stably fixed at the connection point, enhancing the strength of the connection between the crash beam body and the energy-absorbing box during subsequent use. It also improves the ease of repair when the crash beam body and energy-absorbing box are damaged, while maintaining the strength of the fasteners at the connection point and ensuring safety during use.

[0027] This invention incorporates a material feeding and detection mechanism. During the bending operation of the crash beam body, the auxiliary feeding mechanism assists in feeding the aluminum profile, eliminating the need for manual lifting. Simultaneously, the material feeding and detection mechanism assists in loading and unloading the aluminum profile. While feeding, the mechanism also detects the flatness of the aluminum profile surface. During bending, the mechanism performs intermittent point-based testing on the bent aluminum profile, uniformly sampling points to determine whether the curvature of the bent crash beam body meets the standard. The system categorizes and processes qualified and unqualified anti-collision beams. Qualified aluminum profiles are flipped to the corresponding assembly mechanism via a flipping mechanism. The assembly mechanism aligns the energy-absorbing box with the anti-collision beam body. After alignment, the assembly mechanism performs drilling and riveting assembly operations on the anti-collision beam body and the energy-absorbing box. The system can automatically detect the anti-collision beam body during processing, and loading and unloading can be done without manual labor. After the anti-collision beam body passes the bending test, it can be automatically assembled and spliced ​​with the energy-absorbing box, thus improving the overall processing efficiency.

[0028] This invention features an auxiliary feeding mechanism. During feeding, the aluminum profile to be processed can be automatically lifted and fed by the lifting of a movable plate. The aluminum profile can be clamped by the first and second side clamps during the feeding process to ensure feeding stability. After the aluminum profile is bent, the movable plate, the first and second side clamps can be used to clamp the anti-collision beam body and assist the anti-collision beam body in moving out of the bending area, thereby improving the overall processing efficiency.

[0029] This invention incorporates a material feeding and detection mechanism. After the aluminum profile is in place, the rotation of the rollers assists in the feeding operation. During the feeding process, a distance sensor, in conjunction with a retaining shaft and a first switch, detects the flatness of the aluminum profile surface. In the subsequent bending process, the first switch, retaining shaft, and distance sensor work together to intermittently detect the curvature of the bent anti-collision beam surface. This allows for curvature detection of the anti-collision beam surface during processing. Furthermore, after detection, anti-collision beams with acceptable or unacceptable curvature are classified and processed, improving overall processing efficiency.

[0030] This invention incorporates a flipping mechanism. After the aluminum profile of the anti-collision beam is bent, the anti-collision beam body is conveyed to the flipping mechanism. During the conveying process, a fixing clamp supports the anti-collision beam body. After the anti-collision beam body is conveyed, the fixing clamp clamps the anti-collision beam body and flips it. During the flipping process, the anti-collision beam body can be sorted and unloaded. Qualified anti-collision beam bodies are flipped 180° for subsequent assembly with the energy-absorbing box, while unqualified anti-collision beam bodies are flipped 90° to the unqualified material rack for stacking, thereby improving processing efficiency.

[0031] This invention features an assembly mechanism, an energy-absorbing box positioning sleeve, and an inner clamping plate to hold and position the energy-absorbing box. After the fixed clamping plate drives the anti-collision beam body to rotate into place, the lower connecting frame rotates to face the anti-collision beam body. By utilizing a detection touch shaft, a second switch, a third gear, a third rack, and a dot counter, distance detection can be achieved to ensure that the two energy-absorbing boxes at both ends are accurately aligned on the anti-collision beam body, thus ensuring the assembly effect of the energy-absorbing box and improving the processing effect.

The two fixed clamps 75 can be brought close together or moved away from each other, and the anti-collision beam body 1 to be assembled can be clamped using the fixed clamps 75. With the provision of a flipping mechanism 7, after the aluminum profile of the anti-collision beam body 1 is bent, the anti-collision beam body 1 is conveyed to the flipping mechanism 7. During the conveying process of the anti-collision beam body 1, the fixed clamps 75 can support the anti-collision beam body 1. At the same time, after the anti-collision beam body 1 is conveyed, the fixed clamps 75 can clamp the anti-collision beam body 1. After clamping, the anti-collision beam body 1 can be flipped. During the flipping process, the anti-collision beam body 1 can be sorted and unloaded. The qualified anti-collision beam body 1 is flipped 180° for subsequent assembly with the energy-absorbing box 2. The unqualified anti-collision beam body 1 is flipped 90° to the unqualified material rack 42 for stacking, thereby improving processing efficiency.

[0052] As an optimized manufacturing equipment technology for a lightweight new energy vehicle anti-collision beam according to the present invention, the assembly mechanism 8 includes a stabilizing bracket 81, which is fixedly mounted on the frame 4. Two energy-absorbing box positioning sleeves 82 are movably mounted on the stabilizing bracket 81. The energy-absorbing box positioning sleeves 82 have a hollow structure, and an external robotic arm can place the energy-absorbing box 2 to be assembled inside the energy-absorbing box positioning sleeve 82. Two inner clamping plates 821 are movably mounted inside the energy-absorbing box positioning sleeve 82. The inner clamping plates 821 are driven by an electric cylinder, which is electrically connected to an external controller. The inner clamping plates 821 can be used to fix the energy-absorbing box 2. Extension seats are fixedly mounted on both sides of the inner clamping plates 821. A drilling machine 822 is movably mounted on the extension base and is electrically connected to an external controller. A riveting machine 823 is also movably mounted on the extension base and is electrically connected to an external controller. The drilling machine 822 and the riveting machine 823 can rotate and move laterally and longitudinally. With the above structure, the energy-absorbing box positioning sleeve 82 and the inner clamping plate 821 can clamp and position the energy-absorbing box 2. After the fixed clamping plate 75 drives the anti-collision beam body 1 to flip into place, the fixed clamping plate 75, together with the drilling machine 822 and the riveting machine 823, can assemble, drill, and rivet the anti-collision beam body 1 and the energy-absorbing box 2. Subsequent manual assembly is not required, which improves processing efficiency.

[0053] As an optimized manufacturing equipment technology for a lightweight new energy vehicle anti-collision beam according to the present invention, the assembly mechanism 8 further includes connecting frames 83. Two connecting frames 83 are movably mounted on a stabilizing bracket 81. A third gear 831 is rotatably mounted on the connecting frames 83. The third gear 831 is driven by a servo motor, which is electrically connected to an external controller. Two third racks 832 are fixedly mounted on the stabilizing bracket 81. The third racks 832 mesh with the third gears 831. A dot counter 833 is fixedly mounted between every two teeth on the third racks 832. The dot counter 833 is electrically connected to an external controller. A connecting plate 84 is movably mounted on the connecting frames 83. The connecting plate 84 is driven by a servo motor, which is electrically connected to an external controller. A lower connecting frame 85 is movably mounted on the lower side of the connecting plate 84. The lower connecting frame 85 is driven by an electric cylinder. A detector is movably mounted on the lower connecting frame 85. The measuring shaft 851 and the lower bracket 85 are internally fixed with a second switch 852, which is electrically connected to an external controller. The lower bracket 85 is internally equipped with a connecting component. A distance sensor 43 is also installed on the stabilizing bracket 81 between the two lower brackets 85. The distance sensor 43 can sense the distance between the two lower brackets 85. With the above structure, the energy-absorbing box positioning sleeve 82 and the inner clamping plate 821 can clamp and position the energy-absorbing box 2. After the fixed clamping plate 75 drives the anti-collision beam body 1 to flip into place, the lower bracket 85 rotates to face the side of the anti-collision beam body 1. The measuring shaft 851, the second switch 852, the third gear 831, the third rack 832 and the dot counter 833 work together to realize distance detection to ensure that the two energy-absorbing boxes 2 at both ends are accurately aligned on the anti-collision beam body 1, ensuring the assembly effect of the energy-absorbing box 2 and improving the processing effect.

[0054] As an optimized manufacturing equipment technology for a lightweight new energy vehicle anti-collision beam according to the present invention, the connecting component includes an inner extension shaft 853. Two inner extension shafts 853 are fixedly installed on both sides of the detection contact shaft 851. Two second springs 854 are fixedly installed inside the lower frame 85. The second springs 854 are sleeved with the inner extension shafts 853, and one end of the second spring 854 is fixed to the detection contact shaft 851. By providing the connecting component, the second springs 854 can contact the second switch 852 to trigger the second switch 852 when the detection contact shaft 851 is pushed. At the same time, the inner extension shafts 853 can assist the detection contact shaft 851 in sliding reset.

[0055] A manufacturing process for a lightweight anti-collision beam for new energy vehicles includes the following steps:

[0056] S1: Place the aluminum profile to be bent on the loading rack 41. The movable plate 51 descends to the loading rack 41. The aluminum profile is clamped between the first side clamping plate 53 and the second side clamping plate 55. Then the movable plate 51 rises to the processing area. After the movable plate 51 rises to the position, the aluminum profile is pushed to the position between the two mounting frame plates 643. The roller 644 rotates to push the aluminum profile to be processed toward the bending machine 3. While the aluminum profile is pushed between the rollers 644, the electric cylinder drives the mounting cylinder 63 to move back and forth toward the surface of the aluminum profile. During the movement of the mounting cylinder 63, the abutment 633 can contact the surface of the aluminum profile. The aluminum profile squeezes the abutment 633 and triggers the first switch 632. At the same time that the first switch 632 is triggered, the distance sensor 43 starts to perform a distance measurement. The distance sensor 43 detects the distance to the surface of the aluminum profile to be processed by uniformly dotting the surface.

[0057] S2: After the aluminum profile enters the bending machine 3 and is in place, the bending machine 3 performs bending operations on both ends of the aluminum profile. When one end of the aluminum profile is bent, the bent aluminum profile on one side is pushed again between the upper and lower rollers 644. At this time, it is detected that the bent end of the aluminum profile has entered between the rollers 644 on both sides. At this time, the electric cylinder drives the connecting frame 61 to push towards the aluminum profile, and the two rollers 644 rotate away from the aluminum profile. The abutment 633 contacts the surface of the aluminum profile, and the first switch 6... When 32 is triggered, the distance sensor 43 detects the distance of the aluminum profile. During the detection, an intermittent uniform dot detection operation is adopted. When the end bend of the aluminum profile moves between the rollers 644 on both sides, the front end of the aluminum profile moves between the two fixed clamps 75. The fixed clamps 75 can support the bent anti-collision beam body 1 from the unloading side. Simultaneously, when the end bend of the aluminum profile moves between the rollers 644 on both sides, an intermittent dot arc detection operation is continuously performed on the end.

[0058] S3: After the inspection is completed, the roller 644 continues to convey the bent anti-collision beam body 1 to the flipping mechanism 7. At the same time, the first side clamp 53 and the second side clamp 55 located on the feeding side clamp the bent anti-collision beam body 1. Simultaneously, after clamping the anti-collision beam body 1, the first side clamp 53 and the second side clamp 55 drive the anti-collision beam body 1 to move an appropriate distance away from the bending machine 3. Then the first side clamp 53 and the second side clamp 55 release the bent anti-collision beam body 1. At the same time as the release, the fixed clamp 75 clamps the anti-collision beam body 1. After clamping in place, the movable rotating shaft 71 rotates to drive the bent anti-collision beam body 1 to flip.

[0059] S4: If the curvature of the anti-collision beam body 1 does not meet the standard, the movable shaft 71 drives the anti-collision beam body 1 to rotate 90° clockwise to the side of the corresponding unqualified material rack 42. The fixed clamp 75 is released at any time, and the unqualified anti-collision beam body 1 is placed on the unqualified material rack 42 for centralized storage for subsequent processing. If the curvature of the anti-collision beam body 1 meets the standard, the movable shaft 71 drives the anti-collision beam body 1 to rotate 180° clockwise to the side of the corresponding assembly mechanism 8, preparing for the assembly operation of the anti-collision beam body 1 and the energy-absorbing box 2. At this time, the feeding side position can carry out the next feeding and bending inspection operation of aluminum profile.

[0060] S5: Before assembling the anti-collision beam body 1 and the energy-absorbing box 2, the support frame 21 is docked and assembled with the energy-absorbing box 2. The external robotic arm places the energy-absorbing box 2 inside the energy-absorbing box positioning sleeve 82, and the inner clamping plate 821 clamps and fixes the energy-absorbing box 2. After the anti-collision beam body 1 is flipped to the side of the corresponding assembly mechanism 8, the two lower connecting frames 85 on both sides rotate to the position where the detection contact shaft 851 faces the anti-collision beam body 1. The lower connecting frames 85 move to the middle position, and the detection contact shaft 851 can contact the surface of the anti-collision beam body 1. At the same time as the contact, the second switch 852 is triggered, and the dot counter 833 starts to count dots. The result of the dot counter 833 reflects the distance that the lower connecting frames 85 on both sides move on the surface of the anti-collision beam body 1. The target distance is set in advance by the operator. When the lower connecting frame 85 moves to the target distance... When the distance sensor 43 detects that the distance between the two lower brackets 85 is equal to the distance between the energy-absorbing boxes 2 on both sides of the anti-collision beam body 1 under standard conditions, it indicates that the energy-absorbing box 2 on the energy-absorbing box positioning sleeve 82 is aligned. The lower bracket 85 moves and resets. At this time, the fixed clamp 75 drives the anti-collision beam body 1 to move towards the energy-absorbing box 2 for docking. After docking, the drilling machine 822 drills holes in the anti-collision beam body 1 and the energy-absorbing box 2. After drilling, the machine switches to the riveting machine 823 to perform riveting operations at the drilled holes in the anti-collision beam body 1 and the energy-absorbing box 2. After riveting is completed, the anti-collision beam body 1 and the energy-absorbing box 2 are assembled. The movable rotating shaft 71 drives the assembled anti-collision beam body 1 and the energy-absorbing box 2 to rotate 90° clockwise. The external robotic arm removes the assembled anti-collision beam body 1 and the energy-absorbing box 2, and the processing is completed.

[0061] In use, the aluminum profile to be bent is placed on the loading rack 41, the movable plate 51 is lowered to the loading rack 41, the lifting plate 54 is raised and the first rack 56 and the first gear 57 mesh with each other to drive the second side clamping plate 55 to rotate downward, pushing the aluminum profile to the position between the first side clamping plate 53 and the second side clamping plate 55. Then, the lifting plate 54 is controlled to descend and the first rack 56 and the first gear 57 mesh with each other to drive the second side clamping plate 55 to rotate upward until the aluminum profile is clamped between the first side clamping plate 53 and the second side clamping plate 55. Then the movable plate 51 is raised to the processing area.

[0062] During the ascent of the movable plate 51, the electric cylinder drives the mounting sleeve 62 to push towards the processing area. Simultaneously, the second rack 621 and the second gear 64 mesh with each other, driving the two movable arms 641 to rotate vertically to ensure the normal ascent and loading of the movable plate 51. After the movable plate 51 reaches its position, the mounting sleeve 62 moves back to its original position, the two movable arms 641 rotate back to their original position, the two second side clamps 55 rotate downwards, and the lifting plate 54 rises to lift the aluminum profile, pushing it between the two mounting frame plates 643. The motor starts and drives the roller shaft 644 to rotate. 4. While rotating, the aluminum profile to be processed can be pushed towards the side of the bending machine 3. While the aluminum profile is pushed between the rollers 644, the electric cylinder drives the mounting cylinder 63 to move back and forth on the surface of the aluminum profile. During the movement of the mounting cylinder 63, the abutment 633 can contact the surface of the aluminum profile. The aluminum profile squeezes the abutment 633 and triggers the first switch 632. When the first switch 632 is triggered, the distance sensor 43 starts to perform a distance measurement. The distance sensor 43 detects the distance to the surface of the aluminum profile to be processed in a uniform dot pattern to reflect the flatness of the aluminum profile surface and ensure the subsequent bending effect.

[0063] After the aluminum profile enters the bending machine 3 and is in place, the bending machine 3 clamps the aluminum profile and pushes it towards the bending point to bend both ends of the aluminum profile. When one end of the aluminum profile is bent, the bent aluminum profile is pushed again between the upper and lower rollers 644. At this time, it is detected that the bent end of the aluminum profile has entered between the two rollers 644. At this time, the electric cylinder drives the connecting frame 61 to push towards the aluminum profile, and the two rollers 644 rotate away from the aluminum profile. The abutment 633 contacts the surface of the aluminum profile, the first switch 632 is triggered, and the distance sensor 43 detects the aluminum profile. The distance of the profile is detected by intermittent uniform dot detection. The distance sensor 43 detects the distance at multiple points on the aluminum profile to reflect whether the curvature of the aluminum profile bend meets the standard. When the end bend of the aluminum profile moves between the rollers 644 on both sides, the front end of the aluminum profile moves between the two fixed clamps 75. The fixed clamps 75 can support the anti-collision beam body 1 after bending from the unloading side. Simultaneously, when the end bend of the aluminum profile moves between the rollers 644 on both sides, the intermittent dot curvature detection operation is continuously performed on the end.

[0064] After the inspection is completed, the roller 644 continues to convey the bent anti-collision beam body 1 to the flipping mechanism 7. At the same time, the first side clamp 53 and the second side clamp 55 located on the feeding side clamp the bent anti-collision beam body 1. Simultaneously, after clamping the anti-collision beam body 1, the first side clamp 53 and the second side clamp 55 drive the anti-collision beam body 1 to move an appropriate distance away from the bending machine 3. Then the first side clamp 53 and the second side clamp 55 release the bent anti-collision beam body 1. At the same time as the release, the fixed clamp 75 clamps the anti-collision beam body 1. After clamping in place, the movable rotating shaft 71 rotates to drive the bent anti-collision beam body 1 to flip.

[0065] During the curvature detection process of the anti-collision beam body 1, if the curvature of the anti-collision beam body 1 does not meet the standard, the movable shaft 71 drives the anti-collision beam body 1 to rotate 90° clockwise to the side of the corresponding unqualified material rack 42. At any time, the fixed clamp 75 is released, and the unqualified anti-collision beam body 1 is placed on the unqualified material rack 42 for centralized storage for subsequent processing. If the curvature of the anti-collision beam body 1 meets the standard, the movable shaft 71 drives the anti-collision beam body 1 to rotate 180° clockwise to the side of the corresponding assembly mechanism 8, preparing for the assembly operation of the anti-collision beam body 1 and the energy-absorbing box 2. At this time, the feeding side position can carry out the next feeding and bending detection operation of aluminum profiles.

[0066] Before assembling the anti-collision beam body 1 and the energy-absorbing box 2, the support frame 21 is manually inserted into the inside of the box 2. The support frame 21 and the energy-absorbing box 2 are aligned and engaged by the protrusion 22 and the locking groove 23. After the support frame 21 and the energy-absorbing box 2 are assembled, the external robotic arm places the energy-absorbing box 2 inside the energy-absorbing box positioning sleeve 82. Simultaneously, the inner clamping plate 821 clamps and fixes the energy-absorbing box 2. After the anti-collision beam body 1 is flipped to the side of the corresponding assembly mechanism 8, the two lower connecting frames 85 on both sides rotate until the detection contact shaft 851 faces the anti-collision beam body. In the first position, the servo motor is then started to drive the third gear 831 to rotate and mesh with the third rack 832, causing the lower brackets 85 on both sides to move towards the middle position. During the movement of the lower brackets 85, the detection contact shaft 851 can contact the surface of the anti-collision beam body 1. At the same time as the contact, the second switch 852 is triggered, and the dot counter 833 starts to count dots. The result of the dot counter 833 reflects the distance that the lower brackets 85 on both sides have moved on the surface of the anti-collision beam body 1. The target distance is manually set in advance (the target distance is the installation position of the energy-absorbing box 2 on the anti-collision beam body 1). When the lower bracket 85 moves to the target distance, and at the same time the distance sensor 43 detects that the distance between the two lower brackets 85 is equal to the distance between the energy-absorbing boxes 2 on both sides of the anti-collision beam body 1 in the standard state, it indicates that the energy-absorbing box 2 on the energy-absorbing box positioning sleeve 82 has been aligned. The lower bracket 85 moves back to its original position. At this time, the fixing plate 75 drives the anti-collision beam body 1 to move towards the energy-absorbing box 2 side for docking. After docking, the drilling machine 822... The anti-collision beam body 1 and the energy-absorbing box 2 are drilled. During the drilling process, the support frame 21 can provide support at the drilling position to ensure the stability of the drilling. After drilling, the machine is switched to the riveting machine 823 to perform riveting operation at the drilling position of the anti-collision beam body 1 and the energy-absorbing box 2. After riveting is completed, the anti-collision beam body 1 and the energy-absorbing box 2 are assembled. The movable rotating shaft 71 drives the assembled anti-collision beam body 1 and the energy-absorbing box 2 to rotate 90° clockwise. The external robotic arm removes the assembled anti-collision beam body 1 and the energy-absorbing box 2, and the processing is completed.

5. A process for manufacturing anti-collision beams using the manufacturing equipment described in claim 4, characterized in that, Includes the following steps: S1: Place the aluminum profile to be bent on the loading rack (41), and the movable plate (51) descends to the loading rack (41). The aluminum profile is clamped between the first side clamping plate (53) and the second side clamping plate (55). Then the movable plate (51) rises to the processing area. After the movable plate (51) rises to the position, the aluminum profile is pushed to the position between the two mounting frame plates (643). The roller (644) rotates to push the aluminum profile to be processed toward the bending machine (3). The aluminum profile is on the roller (644). While the electric cylinder drives the mounting cylinder (63) to move back and forth to the surface of the aluminum profile, the abutment (633) can contact the surface of the aluminum profile during the movement of the mounting cylinder (63). The aluminum profile squeezes the abutment (633) and triggers the first switch (632). At the same time that the first switch (632) is triggered, the distance sensor (43) starts to perform a distance measurement. The distance sensor (43) detects the distance to the surface of the aluminum profile to be processed by uniformly dotting the distance. S2: When the aluminum profile enters the bending machine (3) and is in place, the bending machine (3) performs bending operations on both ends of the aluminum profile. After one end of the aluminum profile is bent, the aluminum profile bent on one side is pushed again between the upper and lower rollers (644). At this time, it is detected that the bent end of the aluminum profile has entered between the rollers (644) on both sides. At this time, the electric cylinder drives the connecting frame (61) to push towards the aluminum profile. The two rollers (644) rotate away from the aluminum profile. The abutment shaft (633) contacts the surface of the aluminum profile. The first switch ( 632) is triggered, and the distance sensor (43) detects the distance of the aluminum profile. During the detection, an intermittent uniform dot detection operation is adopted. When the end bend of the aluminum profile moves between the rollers (644) on both sides, the front end of the aluminum profile moves between the two fixed clamps (75). The fixed clamps (75) can support the bent anti-collision beam body (1) from the unloading side. Simultaneously, when the end bend of the aluminum profile moves between the rollers (644) on both sides, an intermittent dot arc detection operation is continuously performed on the end. S3: After the inspection is completed, the roller (644) continues to convey the bent anti-collision beam body (1) to the flipping mechanism (7). At the same time, the first side clamp (53) and the second side clamp (55) located on the feeding side clamp the bent anti-collision beam body (1). Simultaneously, the first side clamp (53) and the second side clamp (55) clamp the anti-collision beam body (1) and drive the anti-collision beam body (1) to move a suitable distance away from the bending machine (3). Then the first side clamp (53) and the second side clamp (55) release the bent anti-collision beam body (1). At the same time as the release, the fixed clamp (75) clamps the anti-collision beam body (1). After the clamp is in place, the movable rotating shaft (71) rotates to drive the bent anti-collision beam body (1) to flip. S4: If the curvature of the anti-collision beam body (1) does not meet the standard, the movable pivot (71) drives the anti-collision beam body (1) to rotate 90° clockwise to the side of the corresponding non-conforming material rack (42). The fixed clamp (75) is released at any time. The non-conforming anti-collision beam body (1) is placed on the non-conforming material rack (42) for centralized storage for subsequent processing. If the curvature of the anti-collision beam body (1) meets the standard, the movable pivot (71) drives the anti-collision beam body (1) to rotate 180° clockwise to the side of the corresponding assembly mechanism (8) to prepare for the assembly operation of the anti-collision beam body (1) and the energy-absorbing box (2). At this time, the feeding side position can carry out the next feeding and bending test operation of aluminum profile. S5: Before assembling the anti-collision beam body (1) and the energy-absorbing box (2), the support frame (21) is connected and assembled with the energy-absorbing box (2). The external robotic arm places the energy-absorbing box (2) inside the energy-absorbing box positioning sleeve (82), and the inner clamping plate (821) clamps and fixes the energy-absorbing box (2). After the anti-collision beam body (1) is flipped to the side of the corresponding assembly mechanism (8), the two lower brackets (85) on both sides rotate to the position where the detection touch shaft (851) faces the side of the anti-collision beam body (1). The lower bracket (85) moves to the middle position, and the detection contact shaft (851) can contact the surface of the anti-collision beam body (1). At the same time as the contact, the second switch (852) is triggered, and the dot counter (833) starts to count dots. The result of the dot counter (833) reflects the distance that the lower brackets (85) on both sides move on the surface of the anti-collision beam body (1). The target distance is set manually in advance. When the lower bracket (85) moves to the target distance, and at the same time the distance sensor (43) detects that the distance between the two lower brackets (85) is equal to the distance between the energy-absorbing boxes (2) on both sides of the anti-collision beam body (1) under the standard state, it means that the energy-absorbing box (2) on the energy-absorbing box positioning sleeve (82) is aligned. The lower bracket (85) moves back to its original position. At this time, the fixing plate (75) drives the anti-collision beam body (1) to move towards the energy-absorbing box (2) for docking. After docking, the drilling machine (822) drills the anti-collision beam body (1). Drilling operation is performed on the energy-absorbing box (2). After drilling, switch to the riveting machine (823) to perform riveting operation at the drilled holes of the anti-collision beam body (1) and the energy-absorbing box (2). After riveting is completed, the anti-collision beam body (1) and the energy-absorbing box (2) are assembled. The movable rotating shaft (71) drives the assembled anti-collision beam body (1) and the energy-absorbing box (2) to rotate 90° clockwise. The external robotic arm removes the assembled anti-collision beam body (1) and the energy-absorbing box (2), and the processing is completed.
