Description

Technical Field

[0001] The present invention relates to the technical field of filament winding, and more particularly to a filament winding head device. Background Art

[0002] Due to its characteristics of light weight, high strength, and high stiffness, carbon fiber composite materials are becoming increasingly important in modern industry. In the aerospace field, carbon fiber composite materials are used to manufacture structural components of aircraft and satellites to reduce weight and improve fuel efficiency. In the automotive industry, they are used to manufacture lightweight body and chassis components to improve fuel economy and performance. In addition, carbon fiber composite materials have also been widely used in the fields of sports equipment, wind turbine blades, building reinforcement, etc.

[0003] With the growing demand for carbon fiber composite materials, the traditional manufacturing methods of manual layup and autoclave curing can no longer meet the needs of large-scale production. Therefore, automatic composite material placement has emerged. The filament winding machine can achieve precise cutting and placement of prepreg tows, improving production efficiency and product quality. The main working process of the filament winding machine includes: the wire feeding system sends the prepreg from the reel and maintains appropriate tension, the filament winding head places the prepreg on the mold along a predetermined path, and at the required places, the cutting system cuts off the prepreg and cures it.

[0070] Embodiment

[0071] As Figures 1-7 shown, the filament laying head device proposed in the embodiment of the present invention includes:

[0072] A frame 1 and two pressing components 2 arranged on the frame 1. Each pressing component 2 is used to press the corresponding filament body conveyed from the steering device body.

[0073] A refeeding component 3, which is installed on the frame 1 through a knuckle bolt and is located below the pressing component 2. The refeeding component 3 is used to convey the filament body conveyed from the two pressing components 2.

[0074] Two cutter components 4, both of which are connected to the frame 1 and are located below the refeeding component 3. The cutter component 4 is used to cut the filament body conveyed by the corresponding side of the refeeding component 3.

[0075] A wire combing component 5, which is connected to the frame 1 and is located below the cutter component 4. The wire combing component 5 is used to lay the filament body cut by the two cutter components 4 on the mold body to be laid.

[0076] Specifically, the frame 1 can play a role in supporting and fixing. The frame 1 is used to connect with the driving device body, and the driving device body is used to provide power for the device. The driving device body is a cylinder, and the telescopic end of the cylinder is connected to the frame 1 to drive the frame 1 to move reciprocally along the Figure 1 vertical direction shown in the figure.

[0077] Two pressing components 2 are installed on the frame 1. Each pressing component 2 can press the four filament bodies conveyed from the corresponding steering device body to prevent the filament body from being retracted due to the tension force generated by the filament body during the filament laying process, thereby affecting the filament laying effect of the device.

[0078] The refeeding component 3 is installed on the frame 1 through a knuckle bolt and is located below the pressing component 2. The refeeding component 3 can convey the eight filament bodies conveyed by the two pressing components 2 to the corresponding cutter component 4 on the side.

[0079] The cutter assembly 4 is connected to the frame 1 so that the cutter assembly 4 is fixed on the frame 1, and each cutter assembly 4 is used to cut the tow body conveyed from the corresponding side of the re-feed assembly 3.

[0080] The wire combing assembly 5 is connected to the frame 1 and is used to aggregate the eight tow bodies cut by the two cutter assemblies 4 and lay them on the to-be-laid die body to achieve the wire laying effect of the device.

[0081] As Figure 1 and Figure 8 shown, in a specific implementation, it further includes:

[0082] The heating assembly 6 is arranged on the frame 1 and is located at the rear side of the wire combing assembly 5;

[0083] Wherein, the heating assembly 6 is used to heat the cut tow body laid on the to-be-laid die body.

[0084] Specifically, the heating assembly 6 heats the cut tow body laid on the to-be-laid die body so that the tow body maintains an appropriate temperature, which is convenient for ensuring that the tow body can be uniformly and tightly attached to the to-be-laid surface of the to-be-laid die body.

[0085] As Figure 1 and Figure 9 shown, in a specific implementation, it further includes:

[0086] The pressing roller assembly 7 is connected to the frame 1 and is located on one side of the wire combing assembly 5, and the pressing roller assembly 7 is used to press the cut tow body laid on the to-be-laid die body.

[0087] Specifically, the pressing roller assembly 7 is used to press the cut tow body laid on the to-be-laid die body so that the tow body can be uniformly and tightly attached to the to-be-laid surface of the to-be-laid die body.

[0088] As Figures 1-3 shown, in a specific implementation, each of the pressing assemblies 2 includes:

[0089] The first bracket 21 and the second bracket 22 which are stacked, a channel for the tow body to pass through is formed between the first bracket 21 and the second bracket 22, and the first bracket 21 is connected to the frame 1;

[0090] The first rotating part 23 is rotatably arranged on the first bracket 21 around the first direction, and the part of the first rotating part 23 facing the second bracket 22 is exposed in the channel;

[0091] The second rotating part 24 is rotatably arranged on the second bracket 22 around the first direction, and the part of the second rotating part 24 facing the first bracket 21 is exposed in the channel;

[0092] Wherein, the first rotating part 23 and the second rotating part 24 have a first working state and a second working state. In the first working state, the first rotating part 23 and the second rotating part 24 exposed in the channel rotate towards each other to drive the filament body passing through the channel to travel. In the second working state, the first rotating part 23 exposed in the channel maintains a static state to block the travel of the filament body passing through the channel;

[0093] The first direction is perpendicular to the stacking direction of the first bracket 21 and the second bracket 22.

[0094] Specifically, as Figure 2 shown, the first direction is perpendicular to the stacking direction of the first bracket 21 and the second bracket 22, that is, the first direction is the horizontal direction. The first bracket 21 and the second bracket 22 are detachably connected, for example: connected by bolts. The first bracket 21 is also used for detachably connecting with the body of the fiber placement head frame 1, for example: connected by bolts. A first rotating part 23 is arranged on the first bracket 21, a second rotating part 24 is arranged on the second bracket 22, the first rotating part 23 and the second rotating part 24 are opposite to each other, the part of the first rotating part 23 facing the second bracket 22 is exposed in the channel, and the part of the second rotating part 24 facing the first bracket 21 is exposed in the channel. The channel is a channel for the filament body to pass through. In the first working state, the first rotating part 23 and the second rotating part 24 exposed in the channel rotate towards each other to drive the filament body passing through the channel to travel; in the second working state, the first rotating part 23 exposed in the channel maintains a static state to block the travel of the filament body passing through the channel. Among them, as Figure 2 and Figure 3 shown, the traveling direction of the filament body in the channel is perpendicular to the first direction. For example: the channel is longitudinal, that is, from top to bottom or from bottom to top, then the first direction is transverse, that is, from left to right or from right to left.

[0095] The pressing assembly 2 provided by the embodiment of the present invention rotates unidirectionally on the first bracket 21 through the first rotation, which can avoid the phenomenon that the filament generates a tension force resulting in the filament being retracted, and effectively solves the technical problems existing in the prior art.

[0096] As Figures 1-3As shown, in a specific implementation, the first bracket 21 has a first hollow along the second direction, and at least one set of recessed portions is provided on a side surface of the first bracket 21 opposite to the second bracket 22. Each set of recessed portions includes two grooves, and the two grooves are arranged along the third direction, and the first hollow is located between the two grooves;

[0097] The second bracket 22 has a second hollow along the second direction, and the first hollow is directly opposite to the second hollow. At least one set of protruding portions corresponding to at least one set of the recessed portions is provided on a side surface of the second bracket 22 opposite to the first bracket 21. The protruding portions and the recessed portions are in one-to-one correspondence in the second direction. Each set of protruding portions includes two protrusions, and the two protrusions are arranged along the third direction, and the second hollow is located between the two protrusions. The protrusions on the same side of the first hollow and the second hollow are embedded in the grooves to form a receiving space having two opposite openings along the third direction. Two corresponding receiving spaces along the third direction form one passage. A portion of the first rotating portion 23 facing the second bracket 22 is exposed in the passage through the first hollow, and a portion of the second rotating portion 24 facing the first bracket 21 is exposed in the passage through the second hollow; The second direction is the stacking direction of the first bracket 21 and the second bracket 22, and the third direction is perpendicular to the first direction and the second direction.

[0098] Specifically, the first hollow is used to expose a portion of the first rotating portion 23 mounted on the first bracket 21 facing the second bracket 22, so as to facilitate the first rotating portion 23 to rotate towards each other with the second rotating portion 24 to drive the filament body traveling in the passage.

[0099] The second hollow is used to expose a portion of the second rotating portion 24 mounted on the second bracket 22 facing the first bracket 21, so as to facilitate the second rotating portion 24 to rotate towards the first rotating portion 23 to drive the filament body traveling in the passage.

[0100] Two grooves are provided on a surface of the first bracket 21 opposite to the second bracket 22. The two grooves are located on both sides of the first hollow and are arranged along the third direction. As Figure 3 shown, the third direction is the vertical direction in the figure. The two grooves in the same vertical direction are a set of recessed portions. At least one set of recessed portions is provided on the first bracket 21. When the number of recessed portions is two or more groups, multiple groups of recessed portions are arranged at intervals along the first direction (as Figure 2 and Figure 3 shown, the first direction is the horizontal direction in the figure), wherein the number of groups of recessed portions is adapted to the number of groups of filament bodies and is in one-to-one correspondence.

[0101] On one side of the second bracket 22 opposite to the first bracket 21, there are two protrusions. The two protrusions are located on both sides of the second hollow, and the two protrusions are arranged along the third direction. Two protrusions located in the same vertical direction form a set of protrusion parts. There are at least one set of protrusion parts on the second bracket 22. When the number of protrusion parts is two sets or more, multiple sets of protrusion parts are arranged at intervals along the first direction. Among them, the number of sets of protrusion parts is the same as the number of sets of recessed parts, and they correspond one by one.

[0102] A set of recessed parts is adapted to and inserted into a set of protrusion parts, that is, one protrusion is inserted into one groove. Hereinafter, taking the insertion of a set of recessed parts into a set of protrusion parts as an example for illustration:

[0103] When the first bracket 21 is connected to the second bracket 22, the protrusions on the same side of the first hollow and the second hollow are inserted into the grooves on the same side to enclose a receiving space having two opposite openings along the third direction. Through the first hollow and the second hollow, the two receiving spaces are connected to form a channel for the filament bundle body to pass through. The number of channels is the same as the number of filament bundle bodies, and they correspond one by one. The part of the first rotating part 23 facing the second bracket 22 is exposed in the channel through the first hollow, and the part of the second rotating part 24 facing the first bracket 21 is exposed in the channel through the second hollow.

[0104] The first rotating part 23 includes a rotating shaft and at least one rotating wheel.

[0105] Pressing rollers are arranged at both ends of the rotating shaft. The pressing rollers are detachably connected to the rotating shaft by bolts, and each pressing roller is detachably connected to the first support by bolts.

[0106] The axial extension direction of the rotating shaft is the same as the first direction. When the number of rotating wheels is two or more, multiple rotating wheels are arranged in sequence along the axial extension direction of the rotating shaft. The number of rotating wheels is the same as the number of filament bundle bodies, and they correspond one by one.

[0107] The rotating wheel is rotationally connected to the rotating shaft through a one-way bearing to achieve one-way rotation. Through the one-way rotation of the rotating wheel, the effects of locking and limiting can be achieved, avoiding the phenomenon that the filament bundle generates a tension force and causes the filament bundle to retract, and effectively solving the technical problems existing in the prior art. The part of the rotating wheel facing the second bracket 22 is exposed in the channel through the first hollow on the first bracket 21.

[0108] The second rotating part 24 includes: at least one rotating wheel, the rotating wheel is rotatably connected to the second hollow, the number of the rotating wheels is the same as the number of the tow bodies, and they correspond one to one, the rotating wheel is rotatably connected to the second hollow through a rotating shaft, and the rotating wheel can also achieve the effect of rotatably connecting to the second hollow through other auxiliary structures. In addition, the part of the rotating wheel facing the first bracket 21 is exposed through the second hollow.

[0109] The number of the rotating wheels is adapted to the number of the rotating wheels and corresponds one to one. When the number of the rotating wheels is two or more, the arrangement of the rotating wheels is the same as the arrangement of the rotating wheels.

[0110] When the rotating wheel cooperates with the rotating wheel in the first working state, the rotating wheel exposed in the channel and the rotating wheel corresponding to the rotating wheel rotate towards each other to drive the yarn bundle body passing through the channel to move forward; when in the second working state, the rotating wheel exposed in the channel maintains a stationary state to block the movement of the yarn bundle body passing through the channel.

[0111] In the present application, the rotating wheel is installed on the second bracket 22 through a support frame, one rotating wheel is adapted to one support frame, and each support frame has a straight section and a raised section, wherein the straight section is in the shape of an "I", and the raised section is in the shape of an "I", the straight section is connected to the raised section, and the straight section and the raised section are perpendicular to each other, and the connection between the raised section and the straight section is located in the middle of the straight section, and the end of the raised section away from the straight section is rotatably connected to the rotating wheel.

[0112] The straight section is connected to a side of the second bracket 22 away from the first bracket 21 along the third direction, so that an end of the raised section away from the straight section passes through the second hollow and faces the corresponding rotating wheel.

[0113] The end of the raised section away from the straight section is provided with a rotating shaft, a rotating wheel is sleeved on the rotating shaft, and the rotating wheel is rotatably connected to the rotating shaft. The rotating shaft and the raised section are connected in a detachable manner, such as bolt connection. The raised section and the straight section are cast into an integrated structure by an integrated casting method.

[0114] Two clamping cylinders 25, each clamping cylinder 25 is connected to the frame 1 through a mounting seat 61, and the connection method can be detachable, such as bolt connection, the output ends of the two clamping cylinders 25 are connected to the second bracket 22, the output ends of the two clamping cylinders 25 are symmetrical relative to the second hollow of the second bracket 22, and the telescopic ends of the two clamping cylinders 25 move synchronously. The telescopic end of each clamping cylinder 25 is detachably connected to the second bracket 22, such as bolt connection, plug-in or inlay connection, and this structural design can facilitate the later maintenance of technicians.

[0115] This application provides a way for the support frame to be movably connected to the second support 22, that is, one end of the straight section of the support frame is hinged to the second support 22 through a pin shaft, the other end of the straight section is connected to the second support 22 through a bolt, and a spring 26 is arranged between the bolt and the straight section.

[0116] The number of springs 26 is the same as the number of support frames and they correspond one by one. The spring 26 is used to provide a resilient force to press the runner and the corresponding rotating wheel against the tow body therebetween, so as to achieve the effect of fixing the position of the tow body. It should be noted that fixing the position of the tow body does not restrict whether the tow body can travel in the corresponding channel. What is fixed is the travel trajectory of the tow body in the corresponding channel, so as to prevent the travel trajectory of the tow body in the corresponding channel from shifting or deviating from between the corresponding runner and rotating wheel.

[0117] The purpose of the hinge is to facilitate the support frame to move away from or close to the second support 22 with the movement of the clamping cylinder 25, and to press or release the pressing state of the tow body between the runner and the corresponding rotating wheel.

[0118] When the driving mechanism drives the second support 22 to contract towards the direction where the first support 21 is located, the support frame moves away from the direction where the first support 21 is located, and the spring 26 is compressed. Under the action of the elastic force, the compressed spring 26 provides a resilient force for the corresponding runner, so that the runner and the corresponding rotating wheel press the tow body therebetween; when the driving mechanism drives the second support 22 to stretch towards the direction where the first support 211 is located, the support frame approaches the second support 22, and the spring 26 gradually returns to its original state as the support frame and the second support 22 approach, and gradually reduces the abutting force on the corresponding runner, so as to release the state where the runner and the corresponding rotating wheel press the tow body therebetween. This structural design can enable the device to well control the tow body and avoid problems with changes in the position of the tow body.

[0119] Such as Figure 1 and Figure 4 shown, in a specific implementation, the re-feed assembly 3 includes:

[0120] a driving motor 31, a first roller assembly 32, a second roller assembly 33, a first runner assembly 34 and a second runner assembly 35;

[0121] The driving motor 31 is fixed on the frame 1. The output end of the driving motor 31 is in transmission connection with the first roller assembly 32. The first roller assembly 32 and the second roller assembly 33 are arranged in parallel. The second roller assembly 33 rotates following the first roller assembly 32. A first runner assembly 34 is arranged on one side of the first roller assembly 32, and a second runner assembly 35 is arranged on one side of the second roller assembly 33. The tow body conveyed by one pressing assembly 2 is clamped between the first roller assembly 32 and the first runner assembly 34, and the tow body conveyed by one pressing assembly 2 is clamped between the second roller assembly 33 and the second runner assembly 35.

[0122] Specifically, the driving motor 31 is fixed on the frame 1 by bolts. The output end of the driving motor 31 can drive the first roller assembly 32 to rotate through the transmission connection with the first roller assembly 32. The first roller assembly 32 and the second roller assembly 33 are arranged on the fiber placement head frame 1 and can achieve the rotation effect. The first roller assembly 32 and the second roller assembly 33 are arranged in parallel and are in meshing transmission through gears, so that the second roller assembly 33 rotates following the first roller assembly 32. The rotation directions between the two are opposite. The first roller assembly 32 rotates counterclockwise, and the second roller assembly 33 rotates clockwise.

[0123] A first runner assembly 34 is arranged on one side of the first roller assembly 32, and a second runner assembly 35 is arranged on one side of the second roller assembly 33. When several runners on the first runner assembly 34 approach the first roller assembly 32 respectively, relying on the pressing force between the two and the counterclockwise rotation of the first roller assembly 32, the tow body on the left is transmitted downward, and the clamping force and the laying of several tow bodies can be controlled separately by controlling the distance. When several runners on the second runner assembly 35 approach the second roller assembly 33 respectively, relying on the pressing force between the two and the clockwise rotation of the second roller assembly 33, the tow body on the right is transmitted downward.

[0124] Both the first runner assembly 34 and the second runner assembly 35 can separately control four tow bodies on one side, and a total of eight tow bodies can be separately controlled on both sides. The number of runners can be increased or decreased according to the actual composite material placement requirements, so as to change the number of tow bodies.

[0125] The driving motor 31 includes a motor body, a first synchronous pulley, a thrust bearing and a synchronous belt;

[0126] The motor body is fixed on the frame 1. A first synchronous pulley and a thrust bearing are sleeved on the output shaft of the motor body. The first synchronous pulley is in transmission connection with the first roller assembly 32 through a synchronous belt.

[0127] The motor body is fixed on the frame of the wire laying head, and the first synchronous wheel and the thrust bearing are sequentially sleeved on the output shaft of the motor body. The first synchronous wheel is a component used for synchronous transmission, which is used in conjunction with the synchronous belt to transmit the rotational power to the first roller assembly 32, and the thrust bearing is used to bear the axial force to prevent the first synchronous wheel from moving in the axial direction and sliding out of the output shaft.

[0128] The first roller assembly 32 includes a first roller body, a second synchronous wheel and a first transmission gear;

[0129] One end of the first roller body is sleeved with a second synchronous wheel, and the other end of the first roller body is sleeved with a first transmission gear. The first roller body is arranged in parallel with the second roller assembly 33, and the second synchronous wheel is transmission-connected with the output end of the driving motor 31. The first transmission gear drives the second roller assembly 33 to rotate.

[0130] The second roller assembly 33 includes a second roller body and a second transmission gear; the second roller body is arranged in parallel with the first roller body, one end of the second roller body is meshed with the first transmission gear and connected with the second transmission gear, and the end of the first roller body close to the driving motor 31 is provided with a second synchronous wheel, and the second synchronous wheel and the output end of the driving motor 31 are connected by a synchronous belt. At this time, the driving motor 31 provides power to drive the second synchronous wheel to rotate, and then drive the first roller body to rotate counterclockwise, and the other end of the first roller body away from the driving motor 31 is provided with a first transmission gear, and the first transmission gear rotates with the first roller body and meshes with the second roller assembly 33 as a power output gear and drives the rotation, so that the second roller assembly 33 rotates clockwise to provide power for the downward transportation of the tow body.

[0131] The transmission ratio between the first transmission gear and the second transmission gear is 1:1, and the number of teeth of the first transmission gear and the second transmission gear is the same, that is, the transmission ratio is 1:1; the same transmission ratio can ensure that when switching between left and right wire laying, the wire bundle bodies on both sides can be laid evenly in turn, preventing the wire bundle bodies on both sides from descending to the pressure roller at different speeds due to different transmission ratios, resulting in uneven final laying.

[0132] The first rotating wheel assembly 34 includes a bracket, a first U-shaped bracket, a first pin shaft, a first ball pin, a first rotating wrench, a valve island, a cylinder, a water drop plate and a first rotating wheel;

[0133] The bracket is arranged at the side of the first roller assembly 32. At both ends of the bracket, there are first U-shaped brackets. The first pin shaft is clamped in the groove of the first U-shaped bracket. One end of the first pin shaft is fixedly connected to the first ball pin, and the other end of the first pin shaft is connected to the first rotating wrench. A valve island is arranged at the top of the bracket. The valve island is pneumatically connected to several cylinders through pipelines. The output end of each cylinder is hinged with a water-drop-shaped plate. A first runner is arranged between two adjacent water-drop-shaped plates. One side of the tow body is clamped between the first runner and the first roller assembly 32.

[0134] The bottom end of the bracket is in a hook shape, and the end of the water-drop-shaped plate is placed at the hook of the bottom end of the bracket.

[0135] The bracket is arranged at the side of the first roller assembly 32. Two first U-shaped brackets are welded at both ends of the bracket. The first U-shaped brackets are used for installing and disassembling the first runner assembly 34 from the frame 1. Two first pin shafts are respectively clamped in the grooves inside the first U-shaped brackets at both ends and can rotate in the grooves. One end of the first pin shaft is fixedly connected to the first ball pin. The first ball pin is formed by welding a sphere and two cylinders. The other end of the first pin shaft is connected to the first rotating wrench. When it is necessary to disassemble or install, rotate the first rotating wrench. At this time, the first ball pin also rotates through the first pin shaft, changing from the longitudinal state to the transverse state. At this time, grasp the first rotating wrench and slide it outwards, and the first runner assembly 34 can be installed and removed from the fiber placement head frame 1.

[0136] A valve island is arranged at the top of the bracket. The valve island integrates multiple valves, sensors, actuators and other fluid control components in a frame 1 to achieve more efficient, compact and flexible control. The valve island is pneumatically connected to several cylinders through pipelines to control each cylinder separately. The output end of each cylinder is vertically hinged downwards with a water-drop-shaped plate. When several tow bodies need to be transported down to the fiber placement head pressure roller end, the valve island is used to control the cylinders to expand and contract. At this time, the water-drop-shaped plates will also bounce obliquely upwards to the right, so as to realize that the first runner arranged between two adjacent water-drop-shaped plates extends close to or away from the first roller assembly 32. At the same time, there is only one tow body on each first runner, realizing the separate control of the tow bodies during the fiber placement process. At the same time, the increased pressing force will also ensure the stability of the tow bodies during the fiber placement process.

[0137] The bottom end of the bracket is in a hook shape, and the end of the water-drop-shaped plate is placed at the hook of the bottom end of the bracket. The hook shape is designed according to the overall structure of the fiber placement machine to prevent the water-drop-shaped plate from bouncing too high obliquely upwards due to excessive power, too strong elasticity or inertia of the cylinder, resulting in friction between the first runner and the first roller body. The end of the water-drop-shaped plate is placed at the hook of the bottom end of the bracket, which will limit the water-drop-shaped plate when it reaches a certain height.

[0138] In an embodiment of the present invention, the second runner assembly 35 includes a support block, a second U-shaped bracket, a second pin shaft, a second ball pin, a second turning wrench, a pneumatic push rod, a fixing plate, and a second runner;

[0139] The support block is arranged on the side of the second roller assembly 33. Second U-shaped brackets are provided at both ends of the support block. The second pin shaft is clamped in the groove of the second U-shaped bracket. One end of the second pin shaft is fixedly connected to the second ball pin, and the other end of the second pin shaft is connected to the second turning wrench. A plurality of pneumatic push rods are fixedly connected to the side of the support block away from the second roller assembly 33. The output end of each pneumatic push rod is hinged to a fixing plate. A second runner is provided between two adjacent fixing plates. The tow body is clamped between the second runner and the second roller assembly 33.

[0140] The detachable part of the second runner assembly 35 is the same as that of the first runner assembly 34. Second U-shaped brackets are welded at both ends of the support block. Two second pin shafts are respectively clamped in the grooves in the second U-shaped brackets at both ends and can rotate in the grooves. One end of the second pin shaft is fixedly connected to the second ball pin. The second ball pin is formed by welding a sphere and two cylinders. The other end of the second pin shaft is connected to the second turning wrench. When disassembling or installing, rotate the second turning wrench. At this time, the second ball pin also rotates through the second pin shaft, changing from the longitudinal state to the horizontal state. At this time, hold the second turning wrench and slide it outwards, and the first runner assembly 34 and the second runner assembly 35 can be installed and removed from the fiber placement head frame 1.

[0141] A plurality of pneumatic push rods are fixed on the support block. The output end of each pneumatic push rod is hinged downwards to a fixing plate. A second runner is provided between two adjacent fixing plates. When the pneumatic push rod is pushed, it drives the second runner to move closer to or away from the left upper oblique direction from the bottom. When several tow bodies on the left need to be transported down to the fiber placement head pressure roller end, the pneumatic push rod expands and contracts. At this time, the fixing plate will also drive the second runner to bounce towards the left upper oblique direction, thereby realizing the extension of the second runner to be closer to or away from the second roller assembly 33. At the same time, each second runner only controls one tow body, realizing the control of individual tow bodies during the fiber placement process. At the same time, the increased pressing force also ensures the stability of the tow body during the fiber placement process.

[0142] As Figure 1 and Figures 5-6 shown, in a specific implementation, each of the cutter assemblies 4 includes:

[0143] A first housing, a connecting component, and a cutter assembly 4 connected in sequence. An accommodation cavity 41 is provided inside the first housing. A material inlet passage 43 is formed between the first housing and the connecting component. The accommodation cavity 41 communicates with the material inlet passage 43. A cutter passage 42 is provided inside the connecting component. The extending direction of the cutter passage 42 intersects and communicates with the extending direction of the material inlet passage 43. The connecting component is connected to the frame 1. The material inlet passage 43 is used for the filament body conveyed by the corresponding side of the refeeding component 3 to pass through;

[0144] An abutting block 44, the abutting block 44 having a first end and a second end facing away from each other. The first end is rotatably connected to the accommodation space;

[0145] An elastic part 45, one end of the elastic part 45 is connected to the accommodation space, and the other end of the elastic part 45 is connected to the second end of the abutting block 44. The elastic part 45 is used to provide a resilient force for the abutting block 44;

[0146] Wherein, the cutter assembly 4 can sequentially pass through the cutter passage 42 and the material inlet passage 43, and abut the filament body against the abutting block 44 in the accommodation cavity 41. The second end of the abutting block 44 compresses the elastic part 45 to cut the filament body.

[0147] Specifically, the cutter assembly 4 includes a cutting knife and a cylinder 46 connected in sequence. The cutting knife is located inside the cutter passage 42. The cylinder 46 is connected to the connecting component. The cutting end of the cutting knife facing away from the cylinder 46 abuts the filament body to be cut against the abutting block 44 in the accommodation cavity 41.

[0148] When the cutting knife abuts the corresponding filament body against the corresponding abutting block 44, the abutting block 44 is subjected to pressure and compresses the elastic part 45, so that the second end of the abutting block 44 rotates in a direction away from the cutter assembly 4, which can effectively avoid hard contact between the cutting knife and the abutting block 44, avoid the problem of tool damage, and at the same time extend the service life of the tool.

[0149] After the cutting knife completes the cutting action, the cutting knife releases the abutting effect on the abutting block 44. Under the action of elastic potential energy, the elastic part 45 pushes the abutting block 44 to reset, so as to facilitate the cutting knife to cooperate with the corresponding abutting block 44 to perform the next cutting process on the corresponding filament body.

[0150] It should be noted that the feed channel 43 and the cutter channel 42 can be perpendicular to each other, or they can have a certain angle, which can be an acute angle or an obtuse angle. As long as the feed channel 43 and the cutter channel 42 intersect, since the feed channel 43 and the cutter channel 42 intersect and are connected, the cutting knife can pass through the cutter channel 42 and push the corresponding wire bundle body to be cut in the feed channel 43 against the corresponding abutment block 44 to achieve the effect of cutting the wire bundle body.

[0151] The elastic part 45 includes a spring, one end of which is connected to the side of the accommodating cavity 41 away from the feeding channel 43 , and the other end of the spring is connected to the second end of the abutment block 44 . The spring is used to provide a rebound force for the abutment block 44 .

[0152] The connecting assembly includes a second shell, the cross-sectional shape of the second shell along the first direction is in the shape of a Chinese character "凵", and the second shell has a first side surface and a second side surface opposite to each other along the first direction. Figure 6 In the direction from the first shell to the cutter assembly 4 shown in , the first side is connected to the cylinder 46 so that the cutting knife extends into the interior of the second shell, and a groove is provided on the side surface of the first shell opposite to the second shell, and the groove is recessed toward the other side surface of the first shell away from the one side surface, and the second side surface is connected to the one side surface to form a feed channel 43, and the hollow portion between the first side surface and the second side surface forms a cutter channel 42. The connecting assembly also includes at least one partition plate, which is arranged in the cutter channel 42 and divides the cutter channel 42 into two sub-channels arranged in parallel along the second direction, for each of which a cutting knife passes at the same time. The number of sub-channels, the number of cutting knives, the number of feed channels 43, the number of abutment blocks 44 and the number of elastic parts 45 are all used to adapt to the number of tow bodies to be cut, and correspond one to one. The second direction is as shown in FIG. Figure 6The horizontal direction shown in the figure, where if the first direction is the X-axis direction of a plane, then the second direction is the Y-axis direction of the plane, and the first direction and the second direction are perpendicular to each other within the plane. When there are at least two partition plates, the partition plates are arranged at intervals in the second direction within the second housing and divide the second housing into three sub-channels arranged side by side in the second direction, each for passing a cutting knife. The connecting assembly further includes at least two lower plates, the number of the lower plates being adapted to and corresponding one by one to the number of the sub-channels. Each lower plate is disposed within the corresponding sub-channel and is located below the corresponding cutting knife. A limiting groove is provided within each sub-channel, each limiting groove being located below the corresponding cutting knife. The corresponding lower plate is installed within each limiting groove. At least two first protrusions are provided on the upper plate, the number of the first protrusions being adapted to and corresponding one by one to the number of the sub-channels. The upper plate is disposed on the second housing and covers the corresponding sub-channel through the first protrusions. A second protrusion is provided on one side surface of each lower plate and the corresponding first protrusion, each second protrusion being located below the corresponding cutting knife. Each first protrusion and the corresponding second protrusion are close to the cutting knife within the corresponding sub-channel and are in contact with the corresponding side of the corresponding cutting knife. This structural design can facilitate reducing the space within the sub-channel corresponding to each cutting knife, so as to ensure that the cutting knife corresponding to each sub-channel can reciprocate along a specific travel route, and avoid the situation of route deviation when the cutting knife travels within the corresponding sub-channel, thereby affecting the cutting efficiency of cutting the to-be-cut tow body.

[0153] The connecting assembly further includes an adapter plate disposed on the second housing and close to the second side surface of the second housing; a button lock 47 disposed on the adapter plate, and the button lock 47 on the adapter plate is connected to the button lock 47 on the frame 1.

[0154] The adapter plate is detachably connected to the second housing by bolts. The button lock 47 is a mechanical device mainly used to replace traditional bolts for quick locking operations. It realizes locking and unlocking through button operations without tools, thereby improving work efficiency, especially suitable for occasions that require frequent installation and disassembly.
