Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: As Figure 1 and Figure 2As shown in the figure, a multi-axis winding forming machine for processing medical carbon fiber brackets includes a wire supply mechanism 200 and an impregnation mechanism 400 installed on a bottom plate 100, and also includes a tension adjustment mechanism 300, a wire twisting mechanism 500, and a winding mechanism 600.

[0023] The tension adjustment mechanism 300 is located between the wire supply mechanism 200 and the impregnation mechanism 400, and the tension adjustment mechanism 300 is used to adjust the tension of the carbon fiber tow; the wire twisting mechanism 500 is installed on the top surface of the bottom plate 100; the winding mechanism 600 is installed on the top surface of the bottom plate 100.

[0024] Specifically, during use, the carbon fiber tow on the wire supply mechanism 200 sequentially passes through the tension adjustment mechanism 300, the impregnation mechanism 400, and the wire twisting mechanism 500, and then the carbon fiber tow is connected to the winding mechanism 600.

[0025] When the carbon fiber tow passes through the impregnation mechanism 400, the resin in the impregnation mechanism 400 will adhere to the carbon fiber tow. When the winding mechanism 600 operates, it will wind the carbon fiber tow and drive the wire twisting mechanism 500 to operate, so that the wire twisting mechanism 500 kneads the carbon fiber tow and the resin on the carbon fiber tow, and spreads the resin on the carbon fiber tow evenly, thus avoiding too much or too little resin locally, ensuring uniform bonding between carbon fiber tows, and thereby improving the overall strength and structural density of the bracket.

[0026] As Figures 4 - 6 shown, the winding mechanism 600 includes a fourth bracket 601, a turntable 603, a plurality of mounting grooves 605, multiple groups of fixed toothed plates 606, multiple core molds 607, multiple groups of mounting components 610, a driving component 620, a speed reducer 630, and a wire guiding component 640.

[0027] The fourth bracket 601 is installed on the top surface of the bottom plate 100; the turntable 603 is rotatably connected to the fourth bracket 601; mounting grooves 605 are formed on the fourth bracket 601, the turntable 603 is located in the mounting grooves 605, a guiding strip 602 is installed on the arc-shaped groove 604 of the fourth bracket 601, and an arc-shaped groove 604 is formed on the side surface of the turntable 603, and the arc-shaped groove 604 is slidably connected to the guiding strip 602.

[0028] A plurality of mounting grooves 605 are equidistantly formed on the turntable 603; multiple groups of fixed toothed plates 606 are all installed on the turntable 603; square grooves and clamping grooves are formed on multiple core molds 607; multiple groups of mounting components 610 are used to install the core molds 607 on the turntable 603; the driving component 620 is used to drive the turntable 603 to rotate; the speed reducer 630 is installed on the top surface of the bottom plate 100, a third bevel gear 631 is installed on the input shaft of the speed reducer 630, and a fourth bevel gear 632 is installed on the output shaft of the speed reducer 630; the wire guiding component 640 is installed on the fourth bracket 601 for driving the carbon fiber tow to move.

[0029] Specifically, the mounting assembly 610 can be removed from the turntable 603, and the mandrel 607 can be removed from the mounting assembly 610. By mounting a mandrel 607 on the turntable 603, the winding mechanism 600 can fabricate a cylindrical bracket; by mounting two mandrels 607 on the turntable 603, the winding mechanism 600 can fabricate an elliptical ring-shaped bracket; by mounting three mandrels 607 on the turntable 603, the winding mechanism 600 can fabricate a triangular bracket; by mounting four mandrels 607 on the turntable 603, the winding mechanism 600 can fabricate a quadrilateral bracket. Different-shaped brackets can be fabricated according to the number and positions of the mandrels 607 on the turntable 603.

[0030] As Figure 4 shown, the driving assembly 620 includes a motor 621, a shaft rod 622, a first bevel gear 623, and a second bevel gear 624.

[0031] The motor 621 is mounted on the top surface of the bottom plate 100; the shaft rod 622 is fixedly connected to the power output shaft of the motor 621, and the other end of the shaft rod 622 is fixedly connected to the turntable 603; the first bevel gear 623 is fixedly sleeved on the shaft rod 622, and the first bevel gear 623 is meshed and connected with a third bevel gear 631; the second bevel gear 624 is fixedly sleeved on the shaft rod 622.

[0032] Specifically, when the motor 621 operates, it will drive the shaft rod 622 to rotate, and further drive the turntable 603 to rotate; and when the shaft rod 622 rotates, it will also drive the first bevel gear 623 and the second bevel gear 624 to rotate.

[0033] As Figures 5 - 8 shown, the mounting assembly 610 includes an insertion cylinder 611, two limiting plates 612, two fixing plates 613, a plurality of first springs 614, two movable toothed plates 615, two connecting slide plates 616, a handle 617, an insertion bar 618, and a limiting member 619.

[0034] The inserting cylinder 611 penetrates through the installation groove 605, and the inserting cylinder 611 is in plug-in fit with the core mold 607. A through groove is formed on one side of the inserting cylinder 611; both limiting plates 612 are fixedly connected to the inserting cylinder 611; both fixing plates 613 are fixedly connected to the inserting cylinder 611; a plurality of first springs 614 are respectively fixedly connected to the two fixing plates 613; both movable toothed plates 615 are respectively fixedly connected to the plurality of first springs 614, and the movable toothed plate 615 is in meshing fit with the fixed toothed plate 606; one end of the connecting sliding plate 616 is fixedly connected to the movable toothed plate 615, and the connecting sliding plate 616 penetrates through the fixing plate 613 and is slidably connected to the fixing plate 613; the handle 617 is fixedly connected to the two movable toothed plates 615; the inserting bar 618 is slidably connected to the inserting cylinder 611, the inserting bar 618 is fixedly connected to the handle 617, and a wedge head 6181 is arranged at one end of the inserting bar 618 away from the handle 617.

[0035] Specifically, when it is necessary to adjust the position of the inserting cylinder 611, by pulling the handle 617, the inserting bar 618 and the two connecting sliding plates 616 are driven to move. When the connecting sliding plate 616 moves, it will drive the movable toothed plate 615 to move, so that the movable toothed plate 615 is separated from the fixed toothed plate 606. Then, by moving the handle 617 up or down, the position of the inserting cylinder 611 is adjusted. After the position adjustment of the inserting cylinder 611 is completed, by releasing the handle 617, at this time, affected by the resilience of the first spring 614, the first spring 614 will pull the movable toothed plate 615 to move towards the direction close to the fixed toothed plate 606, so that the movable toothed plate 615 is meshed with the fixed toothed plate 606, and the inserting cylinder 611 cannot move relative to the installation groove 605, thereby fixing the position of the inserting cylinder 611.

[0036] By adjusting the position of the inserting cylinder 611 in the installation groove 605, the position of the core mold 607 on the turntable 603 is further adjusted, so as to adjust the shape of the wound carbon fiber tow support.

[0037] Of course, through the above operations, the inserting cylinder 611 can also be removed from the installation groove 605 to adjust the number of core molds 607 on the turntable 603.

[0038] As Figure 8 shown, the limiting component 619 includes a movable plate 6191, a limiting block 6193, two second springs 6194 and a plurality of telescopic rods 6195. The movable plate 6191 is located inside the inserting cylinder 611. A rocker 6192 is arranged at one end of the movable plate 6191 close to the handle 617, and the rocker 6192 is matched with the wedge head 6181; the limiting block 6193 is installed on the movable plate 6191, the limiting block 6193 is matched with the through groove on the inserting cylinder 611, and the limiting block 6193 is in plug-in fit with the clamping groove in the core mold 607; both second springs 6194 are fixedly connected to the movable plate 6191; a plurality of telescopic rods 6195 are fixedly connected to the movable plate 6191.

[0039] Specifically, when it is necessary to remove the core mold 607 from the insertion cylinder 611, by pulling the handle 617, the insertion strip 618 is driven to move, so that the wedge head 6181 on the insertion strip 618 is separated from the movable plate 6191, and the second spring 6194 pulls the movable plate 6191 to move, so that the limiting block 6193 moves into the insertion cylinder 611, so that the limiting block 6193 is separated from the card slot in the core mold 607, thus facilitating the removal of the core mold 607 from the insertion cylinder 611.

[0040] When it is necessary to fix the core mold 607 on the insertion cylinder 611, first put the core mold 607 on the insertion cylinder 611, align the card slot on the core mold 607 with the limiting block 6193 on the movable plate 6191, and then move the insertion strip 618 into the insertion cylinder 611. The wedge block on the insertion strip 618 will push the movable plate 6191 to move through the rocker 6192, so that the limiting block 6193 moves out of the insertion cylinder 611, so that the limiting block 6193 is inserted into the card slot in the core mold 607, thus facilitating the fixing of the core mold 607 on the insertion cylinder 611.

[0041] As Figure 4 shown, the wire assembly 640 includes a reciprocating lead screw 641, a guide plate 642, a moving seat 643, a guide ring 644 and a fifth bevel gear 645.

[0042] The reciprocating lead screw 641 is rotatably connected to the fourth support 601; the guide plate 642 is fixedly connected to the fourth support 601; the moving seat 643 is sleeved on the reciprocating lead screw 641 and the guide plate 642; the guide ring 644 is installed on the top surface of the moving seat 643; the fifth bevel gear 645 is fixedly connected to the reciprocating lead screw 641, and the fifth bevel gear 645 is meshed with the fourth bevel gear 632.

[0043] Specifically, when the motor 621 drives the shaft rod 622 to rotate, it will drive the third bevel gear 631 to rotate through the first bevel gear 623, and then drive the fifth bevel gear 645 to rotate slowly through the speed reducer 630 and the fourth bevel gear 632, and then drive the reciprocating lead screw 641 to rotate slowly. When the reciprocating lead screw 641 rotates, the moving seat 643 will move horizontally along the reciprocating lead screw 641, and then drive the guide ring 644 to move horizontally. When the guide ring 644 moves, the carbon fiber tow passing through the guide ring 644 will also move, thus facilitating the uniform winding of the carbon fiber tow on the core mold 607.

[0044] As Figure 1 , Figure 2 and Figure 9 shown, the thread rolling mechanism 500 includes a third support 501, a first sliding plate 502, a second sliding plate 503, two mounting plates 506, two gears 507 and a transmission assembly 510.

[0045] The third bracket 501 is installed on the top surface of the bottom plate 100; the first sliding plate 502 is slidably connected to the third bracket 501; the second sliding plate 503 is slidably connected to the third bracket 501, the second sliding plate 503 is located below the first sliding plate 502, and sponge sheets 504 are installed on the opposite sides of the second sliding plate 503 and the first sliding plate 502. The surface of the sponge sheet 504 is coated with resin to prevent the sponge sheet 504 from absorbing the resin on the surface of the carbon fiber tow. Tooth teeth 505 are installed at both ends of the second sliding plate 503 and the first sliding plate 502; two mounting plates 506 are both installed on the third bracket 501; two gears 507 are respectively rotatably installed on the two mounting plates 506, the gears 507 are located between the second sliding plate 503 and the first sliding plate 502, and the gears 507 are meshed and connected with the tooth teeth 505 on the second sliding plate 503 and the first sliding plate 502.

[0046] The transmission assembly 510 includes a mounting seat 511, a sixth bevel gear 513, a disc 514 and a hinge plate 515. The mounting seat 511 is installed on the top surface of the bottom plate 100, and a cross bar 512 is rotatably connected to the mounting seat 511; the sixth bevel gear 513 is installed at one end of the cross bar 512, and the sixth bevel gear 513 is meshed and connected with the second bevel gear 624; the disc 514 is installed at the end of the cross bar 512 far from the sixth bevel gear 513; one end of the hinge plate 515 is hinged to the disc 514, and the other end of the hinge plate 515 is hinged to the second sliding plate 503.

[0047] Specifically, when the motor 621 drives the shaft rod 622 to rotate, it will drive the sixth bevel gear 513 to rotate through the second bevel gear 624, and then drive the cross bar 512 and the disc 514 to rotate. When the disc 514 rotates, it will drive the hinge plate 515 to move, and then drive the second sliding plate 503 to reciprocate horizontally. Since a gear 507 is installed between the second sliding plate 503 and the first sliding plate 502, and the gear 507 is meshed with the tooth teeth 505 on the first sliding plate 502 and the second sliding plate 503, when the second sliding plate 503 reciprocates horizontally, the first sliding plate 502 will also reciprocate horizontally, and the running directions of the first sliding plate 502 and the second sliding plate 503 are always opposite, thereby driving the two sponge sheets 504 to move, so that the two sponge sheets 504 knead the carbon fiber tow, so as to spread the resin on the carbon fiber tow evenly, thereby avoiding too much or too little resin locally, ensuring uniform bonding between the carbon fiber tows, and thus improving the overall strength and structural compactness of the bracket.

[0048] As Figure 1 and Figure 2 shown, the wire supply mechanism 200 includes a first bracket 201 and a winding roller 202. The first bracket 201 is installed on the top surface of the bottom plate 100; the winding roller 202 is rotatably connected to the first bracket 201; The resin impregnation mechanism 400 includes a liquid storage tank 401 and three second guide rollers 402. The liquid storage tank 401 is installed on the top surface of the bottom plate 100, and the liquid storage tank 401 is used to hold resin; the three second guide rollers 402 are all installed in the liquid storage tank 401, and the three second guide rollers 402 are arranged in an inverted product shape.

[0049] Specifically, the carbon fiber tow is provided by the winding roller 202 of the wire supply mechanism 200 and is supported by the first bracket 201 to achieve continuous supply. After the carbon fiber tow passes through the second guide roller 402 in the liquid storage tank 401, the resin is infiltrated on the carbon fiber tow.

[0050] As Figure 1 shown, the multi-axis winding forming machine for processing medical carbon fiber brackets further includes a plurality of sockets 101 and a protective frame 102. The plurality of sockets 101 are all installed on the top surface of the bottom plate 100; the protective frame 102 is inserted into the plurality of sockets 101, and the first bevel gear 623, the second bevel gear 624 and the reducer 630 are located below the protective frame 102.

[0051] Specifically, by providing the socket 101 and the protective frame 102, it is possible to prevent the bevel gear 507 from injuring people when rotating.

[0052] Working principle: In specific use, first adjust the number of mandrels 607 on the turntable 603 according to the shape of the medical carbon fiber bracket to be made. When making a cylindrical bracket, install one mandrel 607 on the turntable 603; when making an elliptical ring-shaped bracket, install two mandrels 607 on the turntable 603; when making a triangular bracket, install three mandrels 607 on the turntable 603; when making a quadrilateral bracket, install four mandrels 607 on the turntable 603.

[0053] When it is necessary to adjust the shape of the carbon fiber tow bracket wound, by pulling the handle 617, the insert bar 618 and the two connecting slide plates 616 are driven to move. When the connecting slide plate 616 moves, the movable tooth plate 615 will be driven to move, and then the movable tooth plate 615 is separated from the fixed tooth plate 606. Then, by moving the handle 617 up or down, the position of the insertion cylinder 611 is adjusted. After the position adjustment of the insertion cylinder 611 is completed, by releasing the handle 617, at this time, affected by the resilience of the first spring 614, the first spring 614 will pull the movable tooth plate 615 to move towards the direction close to the fixed tooth plate 606, so that the movable tooth plate 615 is engaged with the fixed tooth plate 606, making the insertion cylinder 611 unable to move relative to the installation groove 605, thereby fixing the position of the insertion cylinder 611. By adjusting the position of the insertion cylinder 611 in the installation groove 605, the position of the mandrel 607 on the turntable 603 is adjusted, thereby adjusting the shape of the carbon fiber tow bracket wound.

[0054] Then, the carbon fiber tow on the winding roller 202 is sequentially passed through the tension adjusting mechanism 300 and the three second guide rollers 402, then through between the two sponge sheets 504, then through the guide ring 644, and then the carbon fiber tow is connected to the core mold 607.

[0055] By starting the motor 621, the shaft rod 622 is driven to rotate, thereby driving the turntable 603 and the core mold 607 to rotate, so as to wind the carbon fiber tow on the core mold 607. And when the motor 621 drives the shaft rod 622 to rotate, the first bevel gear 623 will drive the third bevel gear 631 to rotate, and then drive the fifth bevel gear 645 to rotate slowly through the speed reducer 630 and the fourth bevel gear 632, and then drive the reciprocating lead screw 641 to rotate slowly. When the reciprocating lead screw 641 rotates, the moving seat 643 will move horizontally along the reciprocating lead screw 641, thereby driving the guide ring 644 to move horizontally. When the guide ring 644 moves, the carbon fiber tow passing through the guide ring 644 will also move, so as to facilitate the uniform winding of the carbon fiber tow on the core mold 607.

[0056] When the carbon fiber tow passes through the liquid storage tank 401, the resin in the liquid storage tank 401 contacts the carbon fiber tow, so that the resin adheres to the carbon fiber tow. By applying resin on the carbon fiber tow, moisture, oxygen and corrosive media can be blocked, preventing the performance of the carbon fiber from degrading due to environmental erosion. It is also convenient to bond the carbon fiber tows into a whole to form a structure with high strength and high stiffness.

[0057] And when the motor 621 drives the shaft rod 622 to rotate, the second bevel gear 624 will drive the sixth bevel gear 513 to rotate, and then drive the cross bar 512 and the disc 514 to rotate. When the disc 514 rotates, it will drive the articulated plate 515 to move, and then drive the second slide plate 503 to reciprocate horizontally. Since a gear 507 is installed between the second slide plate 503 and the first slide plate 502, and the gear 507 meshes with the teeth 505 on the first slide plate 502 and the second slide plate 503, when the second slide plate 503 reciprocates horizontally, the first slide plate 502 will also reciprocate horizontally, and the running directions of the first slide plate 502 and the second slide plate 503 are always opposite, thereby driving the two sponge sheets 504 to move, so that the two sponge sheets 504 knead the carbon fiber tow, thereby spreading the resin on the carbon fiber tow evenly, so as to avoid too much or too little resin locally, ensure uniform bonding between the carbon fiber tows, and thus improve the overall strength and structural density of the bracket.

[0058] After the carbon fiber tow winding is completed, the mandrel 607 on the turntable 603 is removed from the mounting assembly 610, and then the mandrel 607 and the carbon fiber tow are heated by an external heating device to cure the carbon fiber tow. Then, the cured carbon fiber tow is removed from the mandrel 607. It should be noted that when removing two or more mandrels 607 from the mounting assembly 610, an external fixing device is required to keep the relative positions of the multiple mandrels 607 unchanged.

[0059] Embodiment 2: As Figure 1 , Figure 2 and Figure 9 shown, in the case where other parts are the same as those in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: The tension adjusting mechanism 300 includes a second bracket 301, two first guide rollers 302, two guide grooves 303, a tension roller 304, two electric push rods 305, two connecting seats 306 and a controller 307.

[0060] The second bracket 301 is installed on the top surface of the bottom plate 100, and the two first guide rollers 302 are both fixedly connected to the second bracket 301; the two guide grooves 303 are both formed on the second bracket 301; the tension roller 304 is slidably connected to the two guide grooves 303, the tension roller 304 is located between the two first guide rollers 302, and a tension sensor is installed on the surface of the tension roller 304; the two electric push rods 305 are respectively installed on the two side surfaces of the second bracket 301; the two connecting seats 306 are respectively rotatably connected to the two ends of the tension roller 304, and the two connecting seats 306 are respectively fixedly connected to the extending ends of the two electric push rods 305; the controller 307 is installed on the side surface of the second bracket 301.

[0061] Working principle: Before use, set the target tension value on the controller 307; during use, the carbon fiber tow passes between the two first guide rollers 302 and the tension roller 304, and the tension sensor on the tension roller 304 will monitor the tension of the carbon fiber tow in real time and transmit the monitored tension data to the control system of the controller 307. The control system compares the monitored data with the target tension value: When the monitored data is greater than the target tension value, it means that the tension of the carbon fiber tow is too high; When the monitored data is less than the target tension value, it means that the tension of the carbon fiber tow is too low.

[0062] When the tension is too high, the control system of the controller 307 will control the two electric push rods 305 to drive the two connecting seats 306 to move upward, thereby driving the tension roller 304 to move upward, shortening the distance between the tension roller 304 and the first guide roller 302, and thus reducing the tension of the carbon fiber tow.

[0063] When the tension is too low, the control system of the controller 307 will control the two electric push rods 305 to drive the two connecting seats 306 to move downward, and then drive the tension roller 304 to move downward, increasing the distance between the tension roller 304 and the first guide roller 302, thereby increasing the tension of the carbon fiber tow.

[0064] Through the precise control of the electric push rod 305 and the tension sensor, the tension of the carbon fiber tow can be monitored and adjusted in real time, ensuring that it maintains a stable tension state during the winding process, avoiding the problems of insufficient accuracy and slow response speed of traditional mechanical tension adjustment devices, effectively preventing the decline in forming quality and weakening of mechanical properties caused by uneven tension of the carbon fiber tow during the winding process, and improving the overall quality of the medical carbon fiber bracket.
