Description

TECHNICAL FIELD

[0001] The patent relates to the field of doubly-fed wind power generators, in particular to a tool for directly binding carbon fibers on workpieces, mainly used for binding carbon fibers on the end of the rotor of a doubly-fed wind power generator (hereinafter referred to as a generator) to fix the end of the rotor coil, and also used for any working condition requiring circumferential binding of carbon fibers. BACKGROUND

[0002] With the demand for model transformation to high-power in the wind power market, the weight of the rotor of the wind power generator gradually increases, and the strength requirement of the end of the motor gradually increases. The conventional glass tape (self-forming, containing glue) cannot achieve the required strength in a limited volume due to its limited strength. If the strength cannot be met, the rotor cannot be made larger, the motor power cannot be continuously increased, and the market demand cannot be met. To solve this problem, it is considered to use carbon fiber with higher strength as the binding material. However, there is no suitable formed carbon fiber binding tape on the market, and loose carbon fiber needs to be directly bound on the rotor. Since carbon fiber has no adhesion, the carbon fiber needs to be glued before being bound on the claw to ensure that the carbon fiber can be baked and solidified as a whole after being bound on the rotor.

[0003] Therefore, a carbon fiber impregnation structure needs to be designed. During the trial production, three problems are mainly encountered: first, the carbon fiber contains too much glue. The scheme is that the carbon fiber is directly immersed in the glue tank by rolling the roller, and it is verified by trial production that the carbon fiber contains too much glue. After being bound on the rotor, too much glue is squeezed out, causing a lot of waste and pollution, and too much glue occupies the space of the carbon fiber, which cannot guarantee the content of the carbon fiber in a limited volume. Second, the carbon fiber is twisted during the impregnation process, and the distance between the six groups of carbon fiber is too large, which is not evenly distributed after being bound on the end of the rotor. Third, the pre-tightening force of the carbon fiber is too small, and the binding is loose. After the trial production, it is found that the carbon fiber is too loose and cannot be straightened after being bound on the end of the rotor, which affects the overall strength. SUMMARY

[0004] The technical problem to be solved by the patent is to provide a tool for directly binding carbon fibers on workpieces. In the tool, the surface of the glue roller is sticky, and the carbon fiber moving from the glue roller only contacts the glue stuck on the roller (a pre-tightening roller group is provided in front of the glue roller to ensure that the glue roller can rotate with the carbon fiber), which reduces the carbon fiber content. A glue scraping roller group structure is added before binding to the rotor to further reduce the carbon fiber content. A lead sleeve and a lead fork are provided to ensure that the carbon fiber of different trays is not twisted during the binding process, and the carbon fiber passes through the lead fork to reduce the distance between the carbon fibers. The pre-tightening force is increased before the carbon fiber is bound on the rotor, and a pre-tightening gravity roller structure is designed to ensure that the carbon fiber is straightened when it is bound on the rotor, and finally to ensure the binding strength of the end of the rotor.

[0005] To achieve the above technical objectives, the technical solution adopted in this patent is as follows:

The axle of the scraper wheel two can be adjusted in the oblong hole in the mounting plate so that the scraper wheel two is close to the scraper wheel one. The clamping device two is connected to the mounting plate and is used to clamp the axle of the scraper wheel two in the direction of the scraper wheel one.

[0011] The axle of the pre-tensioned gravity wheel is placed in the vertical groove of the mounting plate and the axle of the pre-tensioned gravity wheel can move freely up and down in the vertical groove, which extends through the top of the mounting plate.

[0012] The axle of the gravity wheel support wheel is connected to the mounting plate;

[0013] The wire feeding frame, lead sleeve, pre-tightening wheel assembly, rubber roller, lead fork, scraping wheel assembly, pre-tightening gravity wheel, and gravity wheel support wheel are arranged sequentially from front to back.

[0014] As a further improvement of this patent, the top of the wire feeding frame is provided with a vertical opening groove that penetrates the top of the wire feeding frame, and the side of the wire feeding frame is provided with a lateral opening groove that penetrates the side of the wire feeding frame.

[0015] The wire feeding frame has multiple sets, and each set of wire feeding frames includes two symmetrically arranged wire feeding frames. The bottom of the vertical opening slot of each set of wire feeding frames is at a different height, and the bottom of the lateral opening slot of each set of wire feeding frames is at a different height.

[0016] The two ends of the spool in the carbon fiber roll are respectively connected to the vertical or lateral opening slots in two symmetrically arranged wire feeding frames.

[0017] As a further improvement of this patent, the mounting plate is provided with multiple circular through holes for mounting the first pre-tightening wheel, the roller, the first scraping wheel and the gravity wheel support wheel; the mounting plate is provided with multiple waist-shaped holes for mounting the second pre-tightening wheel and the second scraping wheel; and the mounting plate is provided with a strip-shaped vertical groove.

[0018] As a further improved technical solution of this patent, the pre-tensioning wheel one, pre-tensioning wheel two, scraping wheel one, scraping wheel two and gravity wheel support wheel are all made of rolling shafts. The rolling shaft includes a wheel shaft and a sleeve. The sleeve is rotatably connected to the wheel shaft through a bearing. The end face of the wheel shaft has a threaded hole.

[0024] The beneficial effects of this patent are as follows:

[0025] This patent successfully solves the above problems: 1. The carbon fiber coating process is optimized so that the carbon fiber passes over the roller, causing the roller to rotate. Adhesive adheres to the surface of the roller, and the moving carbon fiber only contacts the adhesive on the roller (a pre-tightening wheel assembly is installed in front of the roller to ensure it rotates with the carbon fiber), thus reducing the adhesive content of the carbon fiber. A scraping wheel assembly is added before binding to the rotor to further reduce the adhesive content. 2. Lead holes and lead forks are installed behind the wire feeding frame and after the coating process to ensure that carbon fibers from different trays do not twist during binding. The lead forks also reduce the distance between carbon fibers (approximately 2mm). 3. A pre-tightening force is added before the carbon fiber is bound to the rotor, and a pre-tightening gravity wheel structure is designed to ensure that the carbon fiber is straightened when bound to the rotor, ultimately ensuring the binding strength at the rotor end.

[0045] The specific embodiments of this patent will be further described below with reference to the accompanying drawings:

[0046] like Figures 1-2 As shown, a tooling for directly binding carbon fiber to a workpiece includes a main support 1, a wire feeding frame 2, a pre-tightening wheel set 5, a rubber rolling wheel 6, a wire guide fork 7, a rubber scraping wheel set 8, a pre-tightening gravity wheel 9, and a gravity wheel support wheel 10, etc.

[0047] The front end of the main support 1 is welded and fixed with multiple wire feeding frames 2 for fixing carbon fiber rolls 3. Multiple parallel lead wire sleeves 4 are also fixedly connected to the main support 1. Each lead wire sleeve 4 has a lead wire hole. The left and right sides of the main support 1 are respectively fixedly connected with symmetrically arranged mounting plates 1A. A glue groove 14 is provided at the bottom between the two mounting plates 1A. A lead wire fork 7 is connected between the two mounting plates 1A.

[0048] like Figures 1-2 As shown, the preload wheel assembly 5 includes a preload wheel 5A, a preload wheel 5B, and a clamping device 5C. The two ends of the axle of the preload wheel 5A are respectively connected to two mounting plates 1A. The two ends of the axle of the preload wheel 5B are respectively connected to the slotted holes 1A1 on the two mounting plates 1A. The two ends of the axle of the preload wheel 5B can be adjusted within the slotted holes 1A1 on the mounting plates 1A so that the preload wheel 5B is close to the preload wheel 5A. The clamping device 5C is connected to the mounting plate 1A and is used to clamp the axle of the preload wheel 5B in the direction of the preload wheel 5A.

[0049] The axles of the roller 6 are connected to two mounting plates 1A at both ends and are located directly above the glue groove 14.

[0050] The scraper wheel assembly 8 includes a scraper wheel 8A, a scraper wheel 8B, and a clamping device 8C. The two ends of the axle of the scraper wheel 8A are respectively connected to two mounting plates 1A. The two ends of the axle of the scraper wheel 8B are respectively connected to the slotted holes 1A1 on the two mounting plates 1A. The two ends of the axle of the scraper wheel 8B can be adjusted within the slotted holes 1A1 on the two mounting plates 1A to bring the scraper wheel 8B closer to the scraper wheel 8A. The clamping device 8C is connected to the mounting plate 1A and is used to clamp the axle of the scraper wheel 8B in the direction of the scraper wheel 8A.

[0051] The two ends of the axle of the pre-tensioned gravity wheel 9 are respectively placed in the strip vertical grooves 1A3 of the two mounting plates 1A, and the axle of the pre-tensioned gravity wheel 9 can move freely up and down in the strip vertical grooves 1A3. The strip vertical grooves 1A3 penetrate through the top of the mounting plate 1A.

[0052] The axles of the gravity wheel support wheel 10 are respectively connected to two mounting plates 1A.

[0053] The wire feeding frame 2, wire lead sleeve 4, pre-tightening wheel group 5, rubber rolling wheel 6, wire lead fork 7, rubber scraping wheel group 8, pre-tightening gravity wheel 9, and gravity wheel support wheel 10 are arranged sequentially from front to back.

[0054] In this embodiment, as Figure 3 As shown, the top of the wire feeding frame 2 is provided with a vertical opening slot 2A, which penetrates the top of the wire feeding frame 2, and the side of the wire feeding frame 2 is provided with a lateral opening slot 2B, which penetrates the side of the wire feeding frame 2.

[0055] The wire feeding frame 2 has multiple sets, and each set of wire feeding frames 2 includes two symmetrically arranged wire feeding frames 2. The bottom of the vertical opening slot 2A of each set of wire feeding frames 2 is at a different height, and the bottom of the lateral opening slot 2B of each set of wire feeding frames 2 is at a different height.

[0056] The two ends of the spools in the carbon fiber roll 3 are respectively connected to the vertical opening slots 2A or the side opening slots 2B in two symmetrically arranged pay-off frames 2. The spools are made of rolling shafts 13. Two spools of carbon fiber roll 3 are installed on each pay-off frame 2.

[0057] The wire feeding frame 2 is used to install the tray of carbon fiber roll 3. The open slot design facilitates the loading and unloading of carbon fiber 3A from the tray. The height difference of the three sets of open slots of the wire feeding frame 2 makes the lead wire position of carbon fiber roll 3 at different heights, avoiding the carbon fiber 3A from twisting during the binding process.

[0058] In this embodiment, the pretensioning wheel 5A, the pretensioning wheel 5B, the scraping wheel 8A, the scraping wheel 8B, and the gravity wheel support wheel 10 all adopt rolling shafts 13.

[0059] like Figure 4 As shown, the rolling shaft 13 is a rotating component of the carbon fiber device. The rolling shaft 13 includes a wheel axle 13A, a sleeve 13B, a cover plate 13C, a ball bearing 13D, and bolts. The sleeve 13B is rotatably connected to the wheel axle 13A through the ball bearing 13D, and the cover plate 13C is bolted to the end face of the sleeve 13B. The end face of the wheel axle 13A has a threaded hole, and the threaded hole of the wheel axle 13A is locked to the mounting plate 1A through bolts.

[0060] In this embodiment, as Figures 7-8 As shown, the tightening device 5C and the tightening device 8C have the same structure, including a threaded block 5C1 and a tightening bolt 5C2. The threaded block 5C1 is welded to the mounting plate 1A, and the tightening bolt 5C2 is threaded into the threaded through hole of the threaded block 5C1. The bolt shank end of the tightening bolt 5C2 is used to tighten the axle of the preload wheel 5B or the scraper wheel 8B. When feeding carbon fiber 3A, the tightening bolt 5C2 is loosened, and carbon fiber 3A is introduced between the two rolling shafts (between preload wheel 5A and preload wheel 5B, or between scraper wheel 8A and scraper wheel 8B). Then, the tightening bolt 5C2 is tightened to achieve the performance of the preload wheel group 5 and the scraper wheel group 8.

[0061] In this embodiment, as Figure 5 and Figure 6 As shown, the rubber roller 6 and the pre-tightening gravity roller 9 include a rolling shaft 13 and a hollow barrel 6A welded to the outside of the sleeve in the rolling shaft; the threaded hole at the end of the axle of the rubber roller 6 is locked to the mounting plate 1A by bolts.

[0062] The main function of the roller 6 is to stick the glue in the glue groove 14 to the surface of the roller 6 by rolling. The carbon fiber 3A slides over the top of the roller 6 and sticks the glue. Therefore, the roller 6 needs to be as light as possible (to be easily pulled by the carbon fiber 3A). Therefore, a hollow barrel 6A is welded to the outside of the roller shaft 13 using a 2mm steel plate (to ensure a seal and prevent the glue from penetrating into the hollow barrel 6A during the rolling process).

[0063] The main function of the pre-tightening gravity wheel 9 is to increase the tension when the carbon fiber 3A is tied to the rotor. Therefore, the gravity wheel needs to be as heavy as possible. It is made of 20mm steel plate welded to the outside of the rolling shaft (no need to be sealed) and welded into a hollow barrel 6A. A U-shaped groove (i.e., a strip vertical groove 1A3) is opened at the position where the gravity wheel is installed on the main bracket 1 to ensure that the gravity wheel can move freely upward when the carbon fiber 3A supports the gravity wheel.

[0064] In this embodiment, as Figure 9 As shown, the glue groove 14 is welded to the main support 1, and the front and rear sides of the glue groove 14 are both inclined structures 14A.

[0065] The glue tank 14 is welded from thin stainless steel plates and is mainly used to hold the glue required for carbon fiber 3A. The inclined structure 14A on both sides of the glue tank 14 allows the glue scraped by the glue scraper set 8 to flow freely back to the bottom of the glue tank 14, making it easier for the glue roller 6 to be immersed in the glue and reducing glue waste.

[0066] In this embodiment, as Figure 10 As shown, the lead fork 7 includes a fork 7A (round steel) and seven fork heads 7B (2mm round steel). The fork 7A is welded between two mounting plates 1A, and seven spaced-apart fork heads 7B are welded to the middle of the fork 7A. A carbon fiber 3A passes between adjacent fork heads 7B.

[0067] The structure of the lead fork 7 is that 2mm round steel is evenly welded on the round steel (to ensure that the carbon fiber 3A of different material trays will not be twisted during the binding process, and the carbon fiber 3A can reduce the distance between carbon fiber 3A by passing through the lead fork 7), and finally welded to the mounting plate 1A of the main bracket 1.

[0068] In this embodiment, as Figure 11 As shown, the rear end of the main support 1 is also fixedly connected to a wire guide spool 11. The wire guide spool 11 is provided with a strip-shaped wire guide hole, through which all six carbon fibers 3A pass, thereby limiting the overall width. In this embodiment, the mounting plate 1A has multiple circular through holes 1A2 for mounting the pre-tightening wheel 5A, the rubber roller 6, the rubber scraping wheel 8A, and the gravity wheel support wheel 10. The mounting plate 1A has multiple oblong holes 1A1 for mounting the pre-tightening wheel 5B and the rubber scraping wheel 8B. The mounting plate 1A has a strip-shaped vertical groove 1A3 for mounting the pre-tightening gravity wheel 9.

[0069] The main support 1 is the main support and fixing part of the carbon fiber 3A binding device, and all the above-mentioned components are installed and fixed on the main support 1.

[0070] The main structure of the pre-tightening wheel assembly 5 consists of a tightening device 5C and two sets of rolling shafts. The rolling shaft mounting hole on the main support 1 near the tightening device 5C is a slotted hole 1A1, which ensures that the rolling shaft can move axially and realize the pre-tightening function of the carbon fiber 3A. Its function is to increase the pre-tightening force of the carbon fiber 3A, so as to ensure that the carbon fiber 3A gives sufficient pressure to the rolling wheel 6 when passing through the rolling wheel 6, and ensure that the carbon fiber 3A can drive the rolling wheel 6 to rotate when passing through the rolling wheel 6. The surface of the rolling wheel 6 is glued, thereby achieving the purpose of impregnating the carbon fiber 3A with a small amount of glue.

[0071] The main structure of the scraper wheel set 8 is basically the same as that of the pre-tightening wheel set. It consists of a tightening device 2 8C and two sets of rolling shafts. The rolling shaft mounting hole on the main bracket 1 near the tightening device 2 8C is a waist-shaped hole 1A1, which ensures that the rolling shaft can move axially and realize the scraping function of applying glue to carbon fiber 3A. Its main function is to scrape off the excess glue on the glue-impregnated carbon fiber 3A. When the carbon fiber 3A passes through the scraper wheel set 8, it needs to pass through from the bottom to the top to ensure that the scraped glue drips smoothly into the glue tank 14 (if it passes through from the top, the scraped glue will remain between the two sets of rolling shafts, which is equivalent to the carbon fiber 3A being re-impregnated at this point, and the scraping effect will be weakened).

[0072] The lead hole consists of 6 rubber sleeves (i.e., lead sleeve 4) with a length of about 20mm. Its main function is to guide the carbon fibers 3A of different heights and directions to a fixed position to ensure that the carbon fibers 3A will not be twisted together during the binding process.

[0073] The gravity wheel support wheel 10 consists of two sets of rolling shafts (one set of rolling shafts is shared with the scraper wheel group 8). Its main function is to support the pre-tightening gravity wheel 9 during the binding process of carbon fiber 3A, so as to facilitate the addition of initial tension to the carbon fiber 3A bound to the rotor.

[0074] Note: The carbon fiber coil 3's feed tray and the workpiece 12 (rotor) to be bound are non-patented tooling parts; the traction force for binding the carbon fiber 3A is provided by the workpiece 12 to be bound rotating on the right. In this embodiment, the carbon fiber coil 3 has six feed trays, all located at different heights. The orientation of the unfolded carbon fiber 3A on the six feed trays is shown in [reference needed]. Figure 1 and Figure 2 .

[0075] This patent successfully solves the above problems: 1. The glue application process for carbon fiber 3A is optimized so that carbon fiber 3A passes over the glue roller 6, causing the roller 6 to rotate. Glue adheres to the surface of the roller 6, and the moving carbon fiber placed on the roller 6 only contacts the glue adhered to the roller 6 (to ensure that the roller 6 can rotate with the carbon fiber 3A, a pre-tightening wheel assembly 5 is set in front of the roller 6), thereby reducing the glue content of the carbon fiber 3A. Furthermore, a scraping wheel assembly 8 is added before binding to the rotor to further reduce the glue content of the carbon fiber. 2. A lead wire hole (lead wire sleeve 4) and a lead wire fork 7 are set behind the wire feeder 2 and after glue impregnation to ensure that the carbon fiber 3A from different trays will not twist during binding. The lead wire fork 7 also reduces the distance between carbon fibers (approximately 2mm). 3. A pre-tightening force is added before the carbon fiber 3A is bound to the rotor. A pre-tightening gravity wheel 9 structure is designed to ensure that the carbon fiber 3A is straightened when bound to the rotor, ultimately ensuring the binding strength at the rotor end.

[0076] The scope of protection of this patent includes, but is not limited to, the above-described embodiments. The scope of protection of this patent is determined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this patent.
