Description

Technical Field

[0001] The present invention belongs to the technical field of automobile anti-collision beam production, and particularly relates to a device for laying composite materials of an anti-collision beam. Background Art

[0002] The anti-collision beam is a relatively critical structural component of an automobile, generally including a beam body and two energy absorption boxes provided at both ends of the back surface of the beam body. The back surface of the energy absorption box is a connecting plate. The anti-collision beam plays an important role in the passive safety performance of the automobile. The traditional automobile anti-collision beam has the defect of large weight, which does not conform to the development direction of vehicle body lightweight. In order to reduce the weight of the anti-collision beam itself, metal parts with lighter mass can be used, but this reduces the mechanical strength of the anti-collision beam and cannot meet the collision requirements of the anti-collision beam. In order to improve the mechanical strength of the anti-collision beam, a composite material layer is added to the surface of the collision beam in the prior art.

[0003] For example, the prior art CN 112141034 B proposes an anti-collision beam for a vehicle and a method for forming and manufacturing the anti-collision beam. The outer tube beam and the inner tube beam of the anti-collision beam are both formed by laying multiple carbon fiber plies and infiltrating resin, and the carbon fiber plies are composite material layers; for another example, the prior art CN 110525366 A proposes a carbon fiber composite anti-collision beam and a preparation method. The carbon fiber composite anti-collision beam includes a collision prevention rod, and the collision prevention rod is formed by laminating and adhesively bonding an inner lining on the collision prevention rod and an outer lining on the collision prevention rod. Its cross-sectional shape is a "day" - shaped frame, and the "day" - shaped frame is covered with a collision prevention rod shell, and the collision prevention rod shell is formed by laying or winding fiber cloth on the outside of the "day" - shaped frame formed by laminating the inner lining on the collision prevention rod and the outer lining on the collision prevention rod.

[0004] Currently, there are already automatic fiber placement devices for composite materials in the prior art, but they have not been applied to the production of anti-collision beams, and the existing automatic fiber placement devices have relatively complex structures and high costs. Therefore, during the production process of anti-collision beams, manual laying is often used, which has a large workload and low efficiency. For this reason, the present invention proposes a device for laying composite materials of an anti-collision beam. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a device for laying composite materials of an anti-collision beam, which can automatically lay composite materials on the surface of the anti-collision beam to solve the problems of large workload and low efficiency in manually laying composite materials during the production of anti-collision beams.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A device for laying composite materials of an anti-collision beam includes a workbench, a composite material supply device, a fiber bundle laying mechanism, a fiber bundle cutting mechanism, and a controller; wherein, the composite material supply device is arranged on the top surface of the workbench and has a fiber bundle outlet for导出 fiber bundles. It should be noted that there is an incorrect expression "导出" in the original Chinese text. It should probably be "exporting" or something more appropriate in the context. The translation is adjusted accordingly based on the overall meaning.

[0008] The fiber bundle laying mechanism includes an electric rotary table and at least two anti-collision beam fixing assemblies. The electric rotary table is set on the worktable and is positioned opposite to the fiber bundle outlet of the composite material supply equipment. The at least two anti-collision beam fixing assemblies are evenly distributed on the top surface of the electric rotary table. Each anti-collision beam fixing assembly includes two anti-collision beam retainers for clamping the two connecting plates of the anti-collision beam. The electric rotary table is equipped with fiber bundle retainers for clamping the ends of the fiber bundle. By rotating, the electric rotary table drives the fiber bundle to wrap around the anti-collision beam fixed on its top surface. The worktable is equipped with a height adjuster for adjusting the fiber bundle winding height.

[0009] The fiber bundle cutting mechanism includes a fixed frame, a clamping assembly for clamping the two ends of the front of the anti-collision beam, and a cutting assembly for cutting the excess fiber bundles at both ends of the anti-collision beam. The fixed frame is set on the workbench and located on one side of the electric rotary table. The clamping assembly and the cutting assembly are both mounted on the fixed frame.

[0010] The composite material supply equipment, electric rotary table, anti-collision beam fixer, fiber bundle fixer, height adjuster, clamping assembly, and cutting assembly are all electrically connected to the controller.

[0011] Furthermore, the anti-collision beam fixer includes a groove and a first electrically controlled telescopic rod. An opening is provided on one side of the groove for inserting the anti-collision beam energy-absorbing box.

The electrically controlled lifting rod is electrically connected to the controller.

[0015] Furthermore, the cutting assembly includes a blade holder, two cutting blades disposed at both ends of the blade holder, and a third electrically controlled telescopic rod for driving the blade holder to reciprocate. One end of the third electrically controlled telescopic rod is connected to the blade holder, and the other end is connected to the fixed frame. The third electrically controlled telescopic rod is electrically connected to the controller.

[0016] Furthermore, the clamping assembly includes a clamping block and a fourth electrically controlled telescopic rod. One end of the fourth electrically controlled telescopic rod is connected to the fixed frame, and the other end is movably inserted through the knife holder and connected to the clamping block. The two ends of the clamping block are respectively movably connected to two cutting knives. The fourth electrically controlled telescopic rod is electrically connected to the controller.

[0017] As a preferred embodiment, a composite material laying device for anti-collision beams further includes a traction manipulator for automatically pulling the ends of fiber bundles to fiber bundle holders and a handling manipulator for transporting anti-collision beams to be processed from the loading conveyor belt to the anti-collision beam fixing assembly and for transporting processed anti-collision beams from the anti-collision beam fixing assembly to the unloading conveyor belt, wherein both the traction manipulator and the handling manipulator are electrically connected to the controller.

[0018] Furthermore, the traction manipulator is located on one side of the height adjuster and includes a first base, a first electrically controlled lifting arm, a first rotary motor, a first electrically controlled telescopic arm, a tilting arm, a tilting motor, a second rotary motor, a first electrically controlled clamp, and a camera. The first base is mounted on the workbench. The bottom end of the first electrically controlled lifting arm is connected to the first base, and the top end is connected to one end of the first electrically controlled telescopic arm via the first rotary motor. The other end of the first electrically controlled telescopic arm is provided with a hinge seat. The hinge seat is hinged to the tilting arm via a tilting shaft. The tilting motor is fixedly mounted on the hinge seat and connected to the tilting shaft to drive the tilting arm to swing up and down. The end of the tilting arm away from the hinge seat is connected to the first electrically controlled clamp via the second rotary motor. The camera is mounted on the first electrically controlled clamp.

[0019] Furthermore, the loading conveyor belt and the unloading conveyor belt are both located on one side of the workbench and are on the same straight line, with the handling robot located in the middle of the loading and unloading conveyor belts; the handling robot includes a second base, a second electrically controlled lifting arm, a third rotary motor, a second electrically controlled telescopic arm, and a second electrically controlled clamp; an extension plate is provided on one side of the workbench, the second base is fixedly mounted on the extension plate, the bottom end of the second electrically controlled lifting arm is connected to the second base, and the top end is connected to one end of the second electrically controlled telescopic arm through the third rotary motor, and the other end of the second electrically controlled telescopic arm is connected to the second electrically controlled clamp; the second electrically controlled lifting arm, the third rotary motor, the second electrically controlled telescopic arm, and the second electrically controlled clamp are all electrically connected to the controller.

[0020] By adopting the above technical solution, the present invention has the following beneficial effects:

[0021] 1. This invention enables the automatic laying of composite materials onto the surface of crash beams, avoiding manual laying and effectively reducing the workload of workers. During operation, a certain number of crash beams are first fixed within the crash beam fixing assembly on the electric rotary table. Then, the fiber bundles from the composite material supply equipment are passed over the height adjuster, with the ends of the fiber bundles fixed to the fiber bundle holder. Next, the electric rotary table is activated, rotating to wind the fiber bundles around the front of the crash beams. Simultaneously, the height adjuster adjusts the winding height during the winding process, allowing the fiber bundles to be laid from top to bottom or bottom to top on the front of the crash beams. After the fiber bundles are wound, the tightening assembly is activated to tighten the crash beams, and the cutting assembly, through its reciprocating motion, cuts off the excess material at both ends of the crash beams. Next, the electric rotary table rotates at a set angle, aligning the next crash beam with the tightening and cutting assemblies. This process is repeated until all crash beams have excess material removed. Finally, the processed crash beams are removed.

[0022] 2. The present invention also includes a traction robot and a handling robot. The traction robot is used to automatically pull the ends of the fiber bundle to the fiber bundle fixer, and the handling robot is used to transport the anti-collision beam to be processed from the feeding conveyor belt to the anti-collision beam fixing component and to transport the processed anti-collision beam from the anti-collision beam fixing component to the unloading conveyor belt, so as to realize fully automated production, avoid manual operation, effectively reduce manpower requirements, and have higher production efficiency.

[0023] 3. Compared with existing automatic fiber placement devices for composite materials, this invention has the advantages of simple structure, low cost and high efficiency, and when applied to the production of crash beams, it can effectively improve the production efficiency of crash beams.

[0040] Example 1

[0041] like Figure 1 As shown, a composite material laying device for a crash beam includes a workbench 1, a composite material supply device 2, a fiber bundle laying mechanism 3, a fiber bundle cutting mechanism 6, and a controller (not shown). The composite material supply device 2 is disposed on the top surface of the workbench 1 and has a fiber bundle outlet 21 for discharging fiber bundles 13. The composite material supply device 2 is electrically connected to the controller. The composite material supply device 2 is used to provide composite material-based fiber bundles 13 so that the fiber bundles 13 can be subsequently laid onto the surface of the crash beam 12. The composite material supply device 2 is prior art, and its specific structure is not described in detail in this specification.

[0042] like Figure 2 As shown, the anti-collision beam 12 generally includes a beam body 121 and two energy-absorbing boxes 122 disposed at both ends of the back of the beam body 121. The back of the energy-absorbing box 122 is a connecting plate 123. When laying the composite material, it is only necessary to lay the beam body 121 horizontally, fix the two energy-absorbing boxes 122, and then lay the fiber bundle 13 on the front of the beam body 121.

[0043] like Figure 1-3 As shown, the fiber bundle laying mechanism 3 includes an electric rotary table 31 and at least two anti-collision beam fixing assemblies 32. The electric rotary table 31 is set on the workbench 1 and is positioned opposite to the fiber bundle outlet 21 of the composite material supply equipment 2. At least two anti-collision beam fixing assemblies 32 are evenly distributed on the top surface of the electric rotary table 31, and guide cylinders 34 are provided between adjacent anti-collision beam fixing assemblies 32 to provide a smooth transition.

[0044] The anti-collision beam fixing assembly 32 includes two anti-collision beam fixing devices 33 for clamping the two connecting plates 123 of the anti-collision beam. The electric rotary table 31 and the anti-collision beam fixing devices 33 are both electrically connected to the controller. In this embodiment, four anti-collision beam fixing assemblies 32 are provided on the electric rotary table 31, and there are a total of eight anti-collision beam fixing devices 33, which can fix four anti-collision beams 12 at the same time. Four guide cylinders 34 are provided and evenly distributed.

[0045] like Figure 4 As shown, the anti-collision beam fixing device 33 includes a groove 331 and a first electrically controlled telescopic rod 332. An opening 333 is provided on one side of the groove 331 for the anti-collision beam energy absorption box 122 to be inserted. The size of the opening 333 is smaller than the size of the anti-collision beam connecting plate 123. The first electrically controlled telescopic rod 332 is set in the groove 331, with its telescopic end facing the opening 333, and is provided with a first clamping plate 334. The first electrically controlled telescopic rod 332 is electrically connected to the controller.

[0046] When fixing the anti-collision beam 12, first insert the two energy-absorbing boxes 122 at both ends of the back of the anti-collision beam 12 into the two anti-collision beam fixing openings 333 of the same anti-collision beam fixing assembly 32. Then, the controller controls the first electrically controlled telescopic rod 332 to extend, pressing the two connecting plates 123 together, thus fixing the anti-collision beam 12. When it is necessary to remove the anti-collision beam 12, the controller controls the first electrically controlled telescopic rod 332 to retract, thus releasing the anti-collision beam 12, which can then be removed.

[0047] like Figure 1 , 5 As shown, the electric rotary table 31 is equipped with a fiber bundle holder 4 for clamping the ends of the fiber bundle, and the fiber bundle holder 4 is electrically connected to the controller. Specifically, the fiber bundle holder 4 is mounted on one of the guide cylinders 34, the top surface of which has a groove 341 for the fiber bundle 13 to pass through. The fiber bundle holder 4 includes a second electrically controlled telescopic rod 41 and a second clamping plate 42. The second clamping plate 42 is located in the groove 341 and is connected to the second electrically controlled telescopic rod 41. The second electrically controlled telescopic rod 41 is installed in the guide cylinder 34 and is electrically connected to the controller.

[0048] When the fiber bundle 13 is fixed, the controller controls the electric rotary table 31 to reset to the initial state. At this time, the relative position between the fiber bundle fixer 4 and the composite material supply equipment 2 is fixed. The fiber bundle end is pulled into the fiber bundle fixer 4, and then the controller controls the second electric telescopic rod 41 to extend. The second clamping plate 42 presses against the fiber bundle end, thus fixing the fiber bundle 13.

[0049] like Figure 6 As shown, the electric rotary table 31 rotates, causing the fiber bundle 13 to wind around the anti-collision beam 12 fixed on its top surface. As the fiber bundle 13 winds, it crosses the circumference of the guide cylinder 34. The guide cylinder 34 acts as a transition point, preventing damage to the fiber bundle 13 from the edge of the anti-collision beam 12. While the electric rotary table 31 rotates, the controller simultaneously controls the composite material supply device 2 to continuously supply the fiber bundle.

[0050] like Figure 1 , 7 As shown, a height adjuster 5 for adjusting the winding height of the fiber bundle 13 is provided on the workbench 1. The height adjuster 5 is electrically connected to the controller. Specifically, the height adjuster 5 is located between the composite material supply device 2 and the electric rotary table 31. It includes an electrically controlled lifting rod 51 and a fixed pulley 52 for the fiber bundle 13 to pass over. The bottom end of the electrically controlled lifting rod 51 is connected to the workbench 1, and the top end is connected to the fixed pulley 52. ​​The electrically controlled lifting rod 51 is electrically connected to the controller.

[0051] When the height adjuster 5 is working, the controller controls the electric lifting rod 51 to rise or fall a certain height at regular intervals, thereby driving the fixed pulley 52 and the fiber bundle 13 to rise and fall, so that the fiber bundle 13 can be wrapped at different heights on the front of the anti-collision beam 12, and thus cover the entire front area.

[0052] like Figure 1 , 8 As shown in Figure -10, the fiber bundle cutting mechanism 6 includes a fixed frame 61, a clamping assembly for clamping the two ends of the front of the anti-collision beam, and a cutting assembly for cutting the excess fiber bundles 13 at both ends of the anti-collision beam. The fixed frame 61 is set on the worktable 1 and located on one side of the electric rotary table 31. The clamping assembly and the cutting assembly are both mounted on the fixed frame 61 and are electrically connected to the controller.

[0053] Specifically, the cutting assembly includes a blade holder 62, two cutting blades 63 located at both ends of the blade holder 62, and a third electrically controlled telescopic rod 64 for driving the blade holder 62 to reciprocate. One end of the third electrically controlled telescopic rod 64 is connected to the blade holder 62, and the other end is connected to the fixed frame 61. The third electrically controlled telescopic rod 64 is electrically connected to a controller. In addition, the fixed frame 61 is also provided with two guide rails 611, and both ends of the blade holder 62 are slidably connected to the two guide rails 611 respectively, which helps to improve the operational stability of the blade holder 62 and the cutting blades 63.

[0054] When the cutting assembly is working, the controller first controls the third electrically controlled telescopic rod 64 to extend, pushing the blade holder 62 and the two cutting blades 63 forward to perform the cutting action. After that, the controller controls the third electrically controlled telescopic rod 64 to retract, driving the blade holder 62 and the two cutting blades 63 to reset.

[0055] The clamping assembly includes a clamping block 65 and a fourth electrically controlled telescopic rod 66. One end of the fourth electrically controlled telescopic rod is connected to the fixed frame 61, and the other end is movably inserted through the knife holder 62 and connected to the clamping block 65. Both ends of the clamping block 65 are movably connected to two cutting knives 63 respectively. The fourth electrically controlled telescopic rod 66 is electrically connected to the controller.

[0056] When the clamping assembly is working, the controller first controls the fourth electrically controlled telescopic rod 66 to extend, pushing the clamping block 65 forward to perform the clamping action. After that, the controller controls the fourth electrically controlled telescopic rod 66 to retract, causing the clamping block 65 to reset.

[0057] When the fiber bundle cutting mechanism 6 is working, the controller first controls the clamping component to perform the clamping action to clamp both ends of the anti-collision beam 12, and then controls the cutting component to perform the cutting action to cut off the excess material at both ends of the anti-collision beam 12. After cutting, the material at both ends of the anti-collision beam 12 will not be warped, thus improving the yield rate.

[0058] This invention enables the automatic laying of composite materials onto the surface of the anti-collision beam 12, avoiding manual laying and effectively reducing the workload of workers. During operation, the four anti-collision beams 12 are first fixed within the four anti-collision beam fixing components 32 on the electric rotary table 31. Then, the fiber bundle 13 supplied by the composite material supply device 2 is passed over the height adjuster 5, with the ends of the fiber bundle 13 fixed to the fiber bundle holder 4. Next, the electric rotary table 31 and the composite material supply device 2 are started. The electric rotary table 31 rotates, causing the fiber bundle 13 to wrap around the front of the anti-collision beam 12. Simultaneously, the height adjuster 5 adjusts the winding height during the winding process, allowing the fiber bundle 13 to be laid from top to bottom or bottom to top on the front of the anti-collision beam 12. After the fiber bundle 13 is wound, the clamping assembly is activated to clamp the anti-collision beam 12, and the excess material at both ends of the anti-collision beam 12 is cut off by the reciprocating motion of the cutting assembly. Then, the electric rotary table 31 rotates at a set angle to align the next anti-collision beam 12 with the clamping assembly and the cutting assembly. By operating in sequence, the excess material of all anti-collision beams 12 can be cut off. Finally, the processed anti-collision beams 12 can be taken out.

[0059] Example 2

[0060] like Figure 11-13 As shown, based on Embodiment 1, the anti-collision beam composite material laying device of this embodiment further includes a traction robot 7 for automatically pulling the fiber bundle ends to the fiber bundle holder 4, and a handling robot 8 for transporting the anti-collision beam 12 to be processed from the loading conveyor belt 9 to the anti-collision beam fixing assembly 32 and for transporting the processed anti-collision beam 12 from the anti-collision beam fixing assembly 32 to the unloading conveyor belt 10. Both the traction robot 7 and the handling robot 8 are electrically connected to the controller. The traction robot 7 is also used to automatically remove the residual fiber bundle material on the fiber bundle holder 4 after the anti-collision beam 12 is removed. This configuration enables fully automated production, avoids manual operation, effectively reduces manpower requirements, and has higher production efficiency.

[0061] The traction manipulator 7 can adopt different structures, as long as it satisfies the functions of traction of fiber bundle 13 and removal of residual fiber bundle 13. For example, in this embodiment, the traction manipulator 7 is located on one side of the height adjuster 5, and includes a first base 71, a first electrically controlled lifting arm 72, a first rotary motor 73, a first electrically controlled telescopic arm 74, a tilting arm 75, a tilting motor 76, a second rotary motor 78, a first electrically controlled clamp 79, and a camera 710. The first base 71 is mounted on the workbench 1. The bottom end of the first electrically controlled lifting arm 72 is connected to the first base 71, and the top end is connected to one end of the first electrically controlled telescopic arm 74 through the first rotary motor 73. The other end of the first electrically controlled telescopic arm 74 is provided with a hinge seat 77. The hinge seat 77 is hinged to the tilting arm 75 through a tilting shaft. The tilting motor 76 is fixedly mounted on the hinge seat 77 and connected to the tilting shaft to drive the tilting arm 75 to swing up and down. The end of the tilting arm 75 away from the hinge seat 77 is connected to the first electrically controlled clamp 79 via the second rotary motor 78, and the camera 710 is mounted on the first electrically controlled clamp 79. The first electrically controlled lifting arm 72, the first rotary motor 73, the first electrically controlled telescopic arm 74, the tilting motor 76, the second rotary motor 78, the first electrically controlled clamp 79, and the camera 710 are all electrically connected to the controller.

[0062] During traction, the controller obtains the position of the fiber bundle end and the fiber bundle fixator 4 through the camera 710, and calculates the movement path of the first electrically controlled clamp 79. By controlling the first electrically controlled lifting arm 72, the first rotary motor 73, the first electrically controlled telescopic arm 74, the flipping motor 76, and the second rotary motor 78, it has multiple degrees of freedom, allowing the first electrically controlled clamp 79 to move to any position and be adjusted at any angle, thereby realizing the traction work of the first electrically controlled clamp 79 on the fiber bundle 13.

[0063] In addition, after the operation is completed, the controller obtains the position information of the residual fiber bundle 13 on the fiber bundle fixator 4 through the camera 710, calculates the moving path of the first electronically controlled clamp 79, controls the first electronically controlled clamp 79 to move to the set position, clamps and takes away the residual fiber bundle 13, so as to remove the residual fiber bundle 13 on the fiber bundle fixator 4.

[0064] When the electric rotary table 31 is in the initial position, the position of the fiber bundle holder 4 is fixed. After the cutting process, the end of the fiber bundle is generally relatively close to the fiber bundle cutting mechanism 6. Therefore, in the initial state, the fiber bundle holder 4 should be set on the side close to the fiber bundle cutting mechanism 6 to reduce the traction distance.

[0065] The first electrically controlled clamp 79 can adopt different structures, as long as it can clamp the fiber bundle 13. For example, in this embodiment, the first electrically controlled clamp 79 includes a housing, a drive motor, and two clamping blocks. The housing is connected to a second rotary motor 78, and a camera 710 is mounted on the housing. The housing is hollow inside, with a strip-shaped hole on the front side. The two clamping blocks are slidably mounted in the strip-shaped hole and extend into the housing. A screw is provided inside the housing, and the screw is threadedly connected to the two clamping blocks through two sets of opposite threads. The drive motor is mounted on the housing and connected to the screw. The drive motor drives the screw to rotate, and the screw causes the two clamping blocks to move closer or further apart, realizing the clamping and releasing functions.

[0066] The loading conveyor belt 9 and unloading conveyor belt 10 are both located on one side of the worktable 1 and are on the same straight line. The handling robot 8 is located between the loading conveyor belt 9 and the unloading conveyor belt 10. During loading, the handling robot 8 first clamps the anti-collision beam 12 on the loading conveyor belt 9; then, it rotates 90 degrees clockwise to face the electric rotary table 31; next, it places the anti-collision beam 12 onto the anti-collision beam fixing assembly 32 on the electric rotary table 31; then, the controller controls the electric rotary table 31 to rotate 90 degrees, so that the next anti-collision beam fixing assembly 32 faces the handling robot 8; then, the handling robot 8 rotates 90 degrees counterclockwise to continue clamping the anti-collision beam 12 on the loading conveyor belt 9, and so on, until all four anti-collision beams 12 are fixed on the electric rotary table 31. During unloading, the operation of the handling robot 8 and the electric rotary table 31 is the same.

[0067] The handling robot 8 can adopt different structures, as long as it meets the aforementioned handling functions. For example, in this embodiment, the handling robot 8 includes a second base 81, a second electrically controlled lifting arm 82, a third rotary motor 83, a second electrically controlled telescopic arm 84, and a second electrically controlled clamp 85. An extension plate 11 is provided on one side of the workbench 1. The second base 81 is fixedly installed on the extension plate 11. The bottom end of the second electrically controlled lifting arm 82 is connected to the second base 81, and the top end is connected to one end of the second electrically controlled telescopic arm 84 through the third rotary motor 83. The other end of the second electrically controlled telescopic arm 84 is connected to the second electrically controlled clamp 85. The second electrically controlled lifting arm 82, the third rotary motor 83, the second electrically controlled telescopic arm 84, and the second electrically controlled clamp 85 are all electrically connected to the controller.

[0068] During the handling operation, the controller controls the second electrically controlled lifting arm 82, the third rotary motor 83, and the second electrically controlled telescopic arm 84, so that the second electrically controlled clamp 85 can be moved to any position, thereby realizing the handling operation of the anti-collision beam 12 by the second electrically controlled clamp 85.

[0069] The second electrically controlled clamp 85 can adopt different structures, as long as it can clamp the anti-collision beam 12. For example, in this embodiment, the second electrically controlled clamp 85 includes a concave groove block, a movable clamping plate, and a lead screw motor. The concave groove block is connected to the second electrically controlled telescopic arm 84, with its concave opening facing downwards. The movable clamping plate is slidably installed in the concave groove block, and the lead screw motor is installed on the concave groove block. Its lead screw passes through the concave groove block and is threadedly connected to the movable clamping plate. The lead screw of the lead screw motor is arranged parallel to the second electrically controlled telescopic arm 84. When the second electrically controlled clamp 85 is working, the lead screw motor drives the movable clamping plate to move, cooperating with the side wall of the concave groove block, thereby realizing the clamping and releasing functions of the anti-collision beam 12.

[0070] Compared with existing automatic composite material fiber placement devices, this invention has the advantages of simple structure, low cost and high efficiency, and when applied to the production of anti-collision beam 12, it can effectively improve the production efficiency of anti-collision beam 12.

[0071] The above description is a detailed description of the preferred embodiments of the present invention. However, the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications made under the technical spirit of the present invention should fall within the patent scope covered by the present invention.
