Description

Technical Field

[0001] The present invention relates to the technical field of spoke manufacturing, and particularly relates to a forming device for a tapered section at the end of a spoke. Background Art

[0002] In a prior application by the applicant, a solution for forming a tapered structure at the end of a carbon fiber spoke was proposed. Generally speaking, a tapered section is designed at the end of the spoke, and the outer diameter of this tapered section gradually increases along the length direction of the spoke towards the end position of the spoke. The metal part provided at the end of the spoke can form a limit fit in the length direction with this tapered section, thereby fixing the metal part on the spoke body, solving the problem that it is not easy to combine and fix the metal part at the end of the carbon fiber spoke with the carbon fiber spoke body. And after being assembled onto the rim, the limit fit between the tapered section and the metal part in the length direction can effectively ensure that the spoke has better performance in bearing the tensile forces of the rim and the hub in its length direction. Refer to Figure 1 , in the process of forming this tapered section, the applicant designed a flexible tapered sheet. This tapered sheet unfolds into a right triangle on a plane, and it has two right-angle sides and a hypotenuse. One of the right-angle sides can be attached to the end of the spoke and make the extending direction of this right-angle side consistent with the extending direction of the spoke body. Then, the tapered sheet attached to the end of the spoke is wound around the end of the spoke. Due to the triangular shape characteristics of the tapered sheet itself, a tapered section with an outer diameter gradually increasing towards the end of the spoke will be automatically formed at the end of the spoke. Before forming the tapered section, the metal part on the spoke can be first sleeved onto the spoke body. After the tapered section is formed, the metal part is then sleeved onto the tapered section to form a limit fit between the two.

[0003] Currently, the forming process of the tapered section at the end of the spoke generally adopts an artificial operation method. After manually cutting the material to obtain the tapered sheet, the tapered sheet is then manually wound around the end of the spoke to form the tapered section. This working method has problems of low production efficiency and high labor cost. Summary of the Invention

As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects: Technical solution one provides a spoke end taper section forming device, which mainly includes a frame, an adhesion assembly, a displacement assembly and a rubbing and winding assembly. This forming device can automatically wind the conical sheet to the end of the spoke and form a taper section, which can effectively improve production efficiency and reduce labor costs.

[0010] Among them, the adhesion assembly is provided with a placement part, and the conical sheet can be placed flat on the placement part; the displacement assembly is provided with a receiving groove, a first displacement mechanism and a second displacement mechanism. The receiving groove can be used to receive the spoke, and when the spoke is placed in the receiving groove, the end of the spoke can be exposed from the receiving groove in the first direction, so as to facilitate winding the conical sheet on the exposed end of the spoke subsequently. The first displacement mechanism can drive the spoke to move between the adhesion station and the rubbing and winding station. After the spoke adheres the conical sheet to the end at the adhesion station, it can be driven by the first displacement mechanism to move to the rubbing and winding station, and the conical sheet is wound to the end through the rubbing and winding assembly; the second displacement mechanism can drive the spoke to move up and down at the adhesion station, so that the spoke is seated on the conical sheet and adheres to the conical sheet.

[0011] When performing adhesion, first place the conical piece flat on the placement part of the adhesion component. Then place the spoke in the accommodation groove of the displacement component and expose the end of the spoke. At this time, the second displacement mechanism of the displacement component holds the spoke at a higher position to prevent interference between the spoke and the adhesion component when placing the spoke. Then the second displacement mechanism drives the spoke to move downward so that the spoke can sit on the placement part and adhere to the conical piece. After the adhesion is completed, the second displacement mechanism lifts the spoke to take the conical piece away from the placement part. Then the first displacement mechanism drives the spoke to move in the second direction to the rolling and curling station.

[0012] The rolling and curling component includes a rotation driving mechanism and at least one rolling and curling mechanism. The rolling and curling mechanism can rotate around the first axis under the action of the rotation driving mechanism. At the same time, the rolling and curling mechanism includes a radial driving unit and rolling and curling parts. The radial driving unit can drive multiple rolling and curling parts to move closer to or away from each other radially simultaneously or asynchronously. When these rolling and curling parts move away from each other, a rolling and curling space will be formed between them. The end of the spoke can be moved to this rolling and curling space. Then these rolling and curling parts move closer to each other under the action of the radial driving unit and contact the end of the spoke. Then the rotation driving mechanism drives the rolling and curling mechanism to rotate, and at the same time these rolling and curling parts will also rotate accordingly. During the rotation of the rolling and curling parts, the rolling and curling parts will apply pressure to the conical piece, causing the conical piece to deform. At the same time, it will also press the conical piece against the side wall of the end of the spoke. As the rolling and curling mechanism rotates, the rolling and curling parts will rotate around the end of the spoke for one or more circles until the conical piece is completely attached to the end of the spoke and a tapered section is formed. Through the rolling and curling component, the conical piece can be accurately and efficiently wound into a tapered section surrounding the end of the spoke, and the rotation driving mechanism and the rolling and curling mechanism in the rolling and curling component cooperate with each other to realize the rolling and curling action of the conical piece.

[0013] In addition, the conical piece attached to the end of the spoke is in an unfolded state before rolling and curling, and only one side of it is attached to the end of the spoke. When the spoke is placed in the accommodation groove, the unfolding and laying direction of the conical piece may have different directions. However, during rolling and curling, it is necessary to ensure that the conical piece can contact the rolling and curling parts in the correct way to prevent the conical piece from being wrinkled or deformed due to the extrusion of the rolling and curling parts. At the same time, this extrusion will also lead to the failure of rolling and curling the conical piece. Therefore, the second displacement mechanism not only functions to make the spoke sit on the placement part at the adhesion station, but also drives the spoke to move upward during the process of the spoke entering the position to be rolled and curled. Through this action and the position coordination of the rolling and curling parts, the conical piece can contact the rolling and curling parts, and by setting a definite moving direction, the conical piece can be bent in the direction of its winding direction. At this time, the conical piece will always maintain contact with the rolling and curling parts. Then the rolling and curling parts move closer to each other and contact the end of the spoke. Then, by making the rolling and curling mechanism rotate in the correct direction, the conical piece can be wound around the end of the spoke in the correct way.

[0014] In Technical Solution 2, the placement part is recessed with an adhesion groove. When the conical piece is placed flat on the placement part, it straddles the adhesion groove. The position of the spoke corresponds to the adhesion groove. During the downward movement of the spoke along with the displacement component, the end of the spoke will first come into contact with the conical piece. Then, under the action of the spoke, the conical piece deforms, and at the same time, the spoke falls into the adhesion groove. The bent and deformed part of the conical piece will contact the outer surface of the spoke end. Designing the adhesion groove structure can increase the contact area between the conical piece and the outer surface of the spoke end, thereby improving the firmness of the adhesion of the conical piece to the spoke end. If the conical piece is placed flat on the placement part without the designed adhesion groove structure, when the spoke end sits on the placement part, since the shape of the spoke end is generally cylindrical, only a very small part contacts the conical piece. Thus, even if the spoke end is pressed by the pressing head, the improvement in the firmness of their adhesion is limited. In addition, and more importantly, by setting the adhesion groove, when the conical piece is placed on the placement part, the position where it can be placed has a greater redundancy. It is easy to understand that if the adhesion groove is not set, when adhering the conical piece, in order to prevent the conical piece from having extra edges exposed on the spoke end and interfering with the subsequent adhesion process, it is necessary to ensure that the spoke end sits at the straight-edge position of the conical piece. This requires that the placement position of the conical piece needs to be extremely accurate, and at the same time, the position of the spoke in the displacement component and the position of the displacement component relative to the adhesion component also need to be always consistent. This obviously puts higher requirements on the overall manufacturing accuracy of the equipment, thereby increasing the manufacturing cost of the equipment. In this technical solution, an adhesion groove is set on the placement part, and the conical piece is placed across the adhesion groove. Since the size of the adhesion groove is large, the spoke end can easily enter the adhesion groove, and at the same time, the conical piece will deform with the movement of the spoke end, thus preventing the edge of the conical piece from being exposed outside the spoke end. Therefore, the conical piece does not need to accurately determine the placement position, and only needs to roughly determine the part of the conical piece that straddles the other side of the adhesion groove.

[0015] In addition, the structure of the adhesion groove is further refined so that the depth of the adhesion groove is greater than the radius of the spoke end, and the edge of the groove opening extends towards each other relative to the groove wall, enhancing the wrapping property of the conical piece around the spoke end. When the spoke end falls into the adhesion groove, the conical piece can better wrap the spoke end, forming a tighter fit, further improving the adhesion strength and reliability. This structural design also helps to prevent the conical piece from shifting during the adhesion process and ensures the accuracy of the adhesion position.

[0016] In Technical Solution 3, the adhesion assembly further includes a rotation mechanism, a bevel cutting mechanism, and a feeding and cutting mechanism. The rotation mechanism is provided with a plurality of placement parts arranged circumferentially. When the rotation mechanism stops rotating each time, the positions of these placement parts correspond one by one to the preset feeding station, bevel cutting station, and adhesion station. That is to say, before each rotation, there is a placement part corresponding to the feeding station, bevel cutting station, and adhesion station respectively. After one rotation, the positions of these placement parts will move to the next station. For example, when the feeding station and the bevel cutting station are adjacent, the placement part corresponding to the feeding station when the previous rotation stops will correspond to the bevel cutting station when this rotation stops. With such a setting, these placement parts can circulate among the feeding station, bevel cutting station, and adhesion station through the intermittent rotation of the rotation mechanism. When at the feeding station, the cut material can be laid flat on the placement part. At the bevel cutting station, it can be cut by the bevel cutting assembly. At the adhesion station, the conical sheet obtained after cutting can be removed. Among them, the bevel cutting assembly is arranged at the position corresponding to the bevel cutting station, and it can cut the cut material by a bevel cutting tool head reciprocating in the first direction to obtain a conical sheet with a bevel edge. Then the rotation mechanism continues to rotate, and the placement part with the conical sheet moves to the adhesion station, and the spoke can adhere the conical sheet at the adhesion station. In addition, a feeding and cutting assembly is also provided. The feeding and cutting assembly is located at the feeding station and has a feeding tool head. The feeding tool head can cut the raw material along the second direction to obtain the cut material placed on the placement part. Through the feeding and cutting assembly, automatic cutting and feeding of the raw material can be realized, further improving the degree of automation. At the same time, it also ensures accurate cutting of the raw material and can obtain cut materials suitable for subsequent bevel cutting.

[0017] In Technical Solution 4, a vacuum negative pressure device is provided, and the rotation mechanism includes a rotating disk and a placement block. A first negative pressure channel is arranged in the placement block to vacuum-adsorb and fix the cut material on the placement part through a first negative pressure port provided at the placement part. In this rotation mechanism, the vacuum adsorption method is used to fix the material, which can evenly adsorb the material on the placement part, avoiding material deformation or displacement that may be caused by mechanical clamping, and improving the positioning accuracy and cutting stability. The placement block can be independently replaced, which is convenient for maintenance and replacing placement blocks of different shapes or sizes to adapt to different materials and cutting requirements.

[0018] In Technical Solution 5, the displacement assembly further includes a clamping mechanism. After the spoke is placed in the accommodation groove, the clamping mechanism can clamp and fix the spoke, thereby preventing the spoke from rotating or translating under the influence of the curling assembly during the curling process of the conical sheet. That is to say, the clamping mechanism can further ensure the position and direction of the spoke are fixed. In addition, during the process of the spoke adhering to the conical sheet, the clamping mechanism can also fix the spoke to ensure that the second displacement mechanism can smoothly drive the spoke to move down and adhere to the conical sheet.

[0019] In Technical Solution 6, each rolling mechanism includes two rolling members, which are symmetrically arranged along the radial direction relative to the first direction. The opposite surfaces of the two rolling members respectively form a first rolling surface and a second rolling surface, and both are planes perpendicular to the radial direction. The planar first rolling surface and the second rolling surface can be smoothly attached to the side wall of the end of the spoke during the rolling process, avoiding wrinkles or other irregular shapes when the conical piece is wound. The symmetrical arrangement of the two rolling members can ensure the uniformity of the force on the conical piece during the rolling process, thereby ensuring that the conical piece can be smoothly wound around the end of the spoke after rolling. In addition, a relief portion is provided on the rolling surface of the rolling member. The recessed structure of the relief portion can accommodate the spoke and the conical piece in the relief portion, so that the first rolling surface and the second rolling surface of the two rolling members can come into contact with each other, making the contact between the rolling member and the spoke closer, and avoiding wrinkles on the conical piece during the rolling process due to excessive gaps between the rolling member and the spoke. At the same time, the design of the circular groove and the flat groove plays a positioning role for the end of the spoke and the conical piece respectively, ensuring that the conical piece can be accurately wound around the end of the spoke.

[0020] In Technical Solution 7, the rolling member is designed as a roller. During the rolling process, the roller will also rotate around the second axis. While the roller is rotating, its circumferential surface will always be in contact with the end of the spoke along the length direction of the spoke, and the sliding friction can be converted into rolling friction, significantly reducing the friction force between the rolling member and the conical piece. The smaller friction force makes the winding process smoother, reduces the wear of the conical piece caused by excessive friction, improves the winding efficiency, and at the same time ensures the integrity of the conical piece. Compared with the structure of the rolling member in the above technical solution, the rolling member with a roller structure is simpler in structure, has a lower part cost, and as long as the conical piece can correctly contact the circumferential surface of the roller in the lifting mechanism, the roller can better complete the rolling process, effectively improving the rolling quality of the conical piece.

[0021] In Technical Solution 8, a feeding component is provided. The feeding component corresponds to the loading station and includes a feeding moving mechanism and a pressing mechanism. The feeding moving mechanism has a material bearing part for bearing the original material. The pressing mechanism can move with the material bearing part and has a pressing part facing the material bearing part. The pressing part can cooperate with the material bearing part to tightly press the original material. Then, the feeding moving mechanism moves towards the placing part and places the original material on the placing part. Then, the loading and cutting component cuts off the original material. Through this feeding component, automatic feeding and positioning of the original material can be achieved, making the entire loading process fully automated. Among them, through this feeding component, the dimensional accuracy of the cut material itself and the accuracy of the placement position of the cut material on the placing part can be guaranteed. Specifically, the relative position between the feeding component and the placing part of the loading station is determined, which ensures that the position of the cut material on the placing part along the first direction can be guaranteed to be accurate. At the same time, the feeding moving mechanism in the feeding component moves towards the placing part by a fixed preset distance each time, which can move the cut material forward by a fixed distance along the third direction, so that the end part of the original material with a definite length is placed on the placing part. Then, the original material is cut off by the loading and cutting component. In this way, the accuracy of the size and position of the cut material on the placing part can be guaranteed, thereby improving the accuracy of the cutting position of the bevel cutting component on the cut material in the bevel cutting station.

[0022] In Technical Solution 9, the feeding component further includes a rolling mechanism. The original material is adhered to the release film to form a composite film roll. The form of the composite film roll is convenient for storing the original material and can avoid contamination. At the same time, the composite film roll can be conveniently sleeved on the loading roller shaft of the rolling mechanism. When the composite film roll passes through the feeding moving mechanism and the pressing mechanism, the original material and the release film are peeled off, and the recovery roller shaft rotates synchronously to recover the release film, realizing the automatic separation of the material and the release film and the automatic recovery of the release film. It can cooperate with the feeding moving mechanism and the pressing mechanism in the feeding component, and each mechanism works together during each loading to achieve efficient and accurate loading of the original material.

[0023] In Technical Solution 10, a pressing component is provided. The pressing component includes a hypotenuse pressing mechanism, a feeding pressing mechanism, and an adhesion pressing mechanism. Among them, the hypotenuse pressing mechanism and the feeding pressing mechanism can firmly press the cutting material on the placing part during the cutting process, preventing the material from moving or deforming due to the contact between the cutting head and the material and the movement during cutting, ensuring the cutting accuracy and the accuracy of the hypotenuse shape. At the same time, a hypotenuse cutting groove is provided on the hypotenuse pressing head of the hypotenuse pressing mechanism. The hypotenuse cutting groove provides guidance for the hypotenuse cutting head, enabling the hypotenuse cutting head to perform cutting along a predetermined trajectory, further improving the accuracy and quality of hypotenuse cutting. The adhesion pressing mechanism can move down and press the end of the spoke after adhering the conical piece to the end of the spoke, so that the end of the spoke can firmly adhere to the conical piece. By pressing down on the spoke by the adhesion pressing head, the problem of the insufficient firm adhesion degree between the end of the spoke and the conical piece after the end of the spoke sits on the conical piece can be solved.

[0024] In Technical Solution 11, a waste discharging component is provided at the waste discharging station. The waste discharging station is located between the hypotenuse cutting station and the adhesion station. At the waste discharging station, the waste discharging component can take the waste of the cutting material except the conical piece away from the placing part after the cutting material is cut, facilitating the accurate adhesion of the conical piece to the end of the spoke at the adhesion station. The waste discharging component includes a waste discharging suction head. The waste discharging suction head can form a negative pressure and move to the placing part to adsorb and fix the waste. Then, the waste discharging suction head moves along the horizontal fourth direction. When it reaches the preset waste position, the waste discharging suction head can stop the negative pressure adsorption, so as to discard the waste to a specific position. Through this waste discharging component and the vacuum negative pressure device, the waste generated during the cutting process can be automatically removed from the placing part, avoiding waste accumulation, keeping the working area clean, and improving the operation efficiency and stability of the equipment.

[0025] In Technical Solution 12, a negative pressure connection component is provided, realizing the independent control and distribution of vacuum negative pressure for multiple placing blocks. The first negative pressure port of each placing block is connected to the vacuum negative pressure device through independent second and third negative pressure channels, ensuring that the vacuum adsorption effect of each station is not affected by other stations, and improving the reliability and stability of vacuum adsorption. The cooperation of the negative pressure driving mechanism and the negative pressure connection part can accurately control the application and disconnection of the negative pressure, so as to work in coordination with the movement of the rotating disk. When the rotating disk rotates, the negative pressure connection part moves up to separate the second negative pressure port and the third negative pressure port. After the rotating disk rotates to the designated position and stops, the negative pressure connection part moves down to connect the third negative pressure port with the next second negative pressure port on the rotating disk. Through this negative pressure connection component, in the equipment using a rotating disk, the problem of difficult layout of the negative pressure pipeline caused by the rotation of the rotating disk can be solved, greatly simplifying the layout problem of the negative pressure pipeline.

[0034] Embodiment 1 Refer to Figure 2 , Embodiment 1 of the present invention relates to a forming device for the taper section at the end of a spoke. The forming device is adapted to wind a conical sheet 12 around the end of the spoke to form a taper section, and mainly includes a frame 20, an adhesion assembly 30, a displacement assembly 40, a rubbing and winding assembly 50. In addition, it further includes a vacuum negative pressure device, a feeding assembly 60, a pressing assembly 70, a waste discharging assembly 80 and a negative pressure communication assembly 90.

[0035] First, refer to Figure 1, which shows the structure of the spoke with the conical piece 12 attached. Generally speaking, the spoke includes a spoke body 10, connecting caps 11 and conical pieces 12. The number of connecting caps 11 is two, which are sleeved on the spoke body 10 from both ends respectively. The number of conical pieces 12 is two, which are respectively attached to the two ends of the spoke body 10. The conical piece 12 can be attached to the spoke body 10 by means of gluing. At the same time, one side surface of the conical piece 12 itself can be designed to be sticky, so that when winding, with this side surface as the inner side, the conical piece 12 will not spread after adhesion. The triangular shape of the conical piece 12 can automatically form a tapered section at the end of the spoke after adhesion. The size and shape of the tapered section are adapted to the size and shape of the inner through hole of the connecting cap 11. The connecting cap 11 can be pulled outwards to the position of the tapered section, and the connecting cap 11 and the spoke body 10 can be limited and matched in the length direction through the tapered section, which can effectively improve the pulling force that the connecting cap 11 can withstand when pulling the connecting cap 11. Among them, in this embodiment, the spoke body 10 and the conical piece 12 are made of carbon fiber material, and the connecting cap 11 is made of metal. After the conical piece 12 is wound around the spoke body 10, the conical piece 12 and the spoke body 10 can be cured into one body through a curing process to prevent the conical piece 12 from falling off the spoke body 10. After the two are cured into one body, the connecting cap 11 can be pulled to the position of the tapered section.

[0036] It should be noted that the forming equipment in this embodiment also includes the function of cutting the raw material into the conical piece 12. The raw material is a carbon fiber cloth tape with a certain width. In this embodiment, the sticky side of the carbon fiber cloth tape adheres to the release film, and forms a composite film roll in cooperation with the release film. When cutting, the carbon fiber cloth tape and the release film in the composite film roll can be peeled off by the feeding component 60, and the carbon fiber cloth tape is cut into rectangular cutting materials, and then the cutting materials are cut into conical pieces 12 and waste materials. After that, the waste materials are discharged, and after the conical piece 12 is adhered to the spoke end, the conical piece 12 is wound around the spoke end to form a tapered section.

[0037] Before describing the forming equipment, it is necessary to explain the meanings of the directional terms in the specification and claims of the present invention. Refer to Figures 2 to 23 , in this specification, the front, back, left, right, up and down are used as the direction coordinates. Among them, the left and right directions correspond to the first direction and the fourth direction in the specification and claims, the front and back directions correspond to the second direction and the fifth direction in the specification and claims, and the up and down directions are the up and down directions in the specification and claims. The third direction in the specification and claims is other directions inclined to the front and back directions and the left and right directions.

The frame 20 includes a main support as a supporting body, and a platform 21 arranged above the main support, and the platform 21 and the main support are connected by a slide rail 22 and a slider 23. Specifically, the main support is a table-shaped component, which can be made of aluminum profiles or other materials. The platform 21 is a flat plate-shaped component. There are two platforms 21, which are respectively installed on the main support in the left and right directions. The slide rail 22 and the slider 23 cooperate to form a sliding structure. The slide rail 22 is fixedly installed on the top of the main support, and the slide rail 22 extends in the left and right directions. The slider 23 is installed on the slide rail 22, and the slider 23 can reciprocate along the extension direction of the slide rail 22. The platform 21 is fixed to the slider 23 by bolts, so that the platform 21 can slide in the left and right directions relative to the main support. Through the cooperation of the slide rail 22 and the slider 23, both platforms 21 can slide in the left and right directions, so that the distance and respective positions of the two platforms 21 in the left and right directions can be adjusted. A driving motor or a driving cylinder may be provided on the frame 20 corresponding to each platform 21, so as to control the movement of the platform 21 in an automated manner and accurately adjust the position of the platform 21. In addition, the frame 20 further includes a driving mounting plate 24 in the form of a flat plate, which is fixedly mounted above the platform 21 through a plurality of support rods extending in the up-down direction, and a clearance space is formed between the lower surface of the driving mounting plate 24 and the upper surface of the platform 21, and some components of the pressing assembly 70 and the negative pressure communication assembly 90 are mounted on the driving mounting plate 24. First, the adhesion component 30, the waste discharge component 80 and the negative pressure communication component 90 are introduced.

[0040] The adhesion assembly 30 further includes a rotating mechanism 31, a bevel cutting mechanism 32, and a feeding and cutting mechanism 33; the conical sheet 12 is obtained by cutting a cutting material placed on a corresponding placement part 3121 by the bevel cutting mechanism 32, and the cutting material is obtained by cutting a raw material placed on a corresponding placement part 3121 by the feeding and cutting mechanism 33; the rotating mechanism 31 intermittently rotates relative to the machine frame 20 about a second axis in the up-and-down direction, and a plurality of the placement parts 3121 are circumferentially arranged on the rotating mechanism 31, and when the rotating mechanism 31 stops rotating, one of the placement parts 3121 rotates to the feeding station 251, the bevel cutting station 252, and the adhesion station 254 defined by the machine frame 20 respectively; the feeding station 251, the bevel cutting station 252, and the adhesion station 254 are arranged in sequence along the rotation direction of the rotating mechanism 31; the bevel cutting mechanism 32 is located at the bevel cutting station 252, and it is provided with a bevel cutter head 321 adapted to reciprocate in a horizontal third direction; the bevel cutter head 321 is adapted to cut the cutting material on the placement part 3121 at the bevel cutting station 252 in the third direction to obtain the conical sheet 12 with a bevel; the feeding and cutting mechanism 33 is located at the feeding station 251, and it is provided with a feeding cutter head 331 adapted to reciprocate in a horizontal fourth direction; the feeding cutter head 331 is adapted to cut the raw material in the fourth direction to obtain the cutting material placed on the placement part 3121 at the feeding station 251.

[0041] Each time the rotating mechanism 31 stops rotating, another placement part 3121 rotates to a preset waste discharging station 253, and the waste discharging station 253 is located between the bevel cutting station 252 and the adhesion station 254; the waste discharging assembly 80 is installed on the machine frame 20 and is located at the waste discharging station 253, and it is provided with a waste discharging suction head 81 adapted to reciprocate in a horizontal sixth direction, and includes an ejecting mechanism 84 corresponding to the waste discharging station 253; the waste discharging suction head 81 is adapted to form a negative pressure through the vacuum negative pressure device to take away the waste separated from the conical sheet 12 in the cutting material on the placement part 3121 at the waste discharging station 253 from the placement part 3121; the ejecting mechanism 84 is provided with an ejecting rod 841 adapted to reciprocate in the up-and-down direction; the placement block 312 is provided with an ejecting channel 3125 penetrating in the up-and-down direction at a position corresponding to the waste separated from the conical sheet 12 in the cutting material; the ejecting rod 841 is adapted to extend into the ejecting channel 3125 and eject the waste from the placement block 312 to cooperate with the waste discharging suction head 81 to take away the waste.

[0042] Continue to refer to Figure 1, the forming device according to the embodiments of the present invention is used to cut materials into conical pieces 12 for winding the ends of spokes. In the description and claims of the present invention, the materials include two cases. One is the cut material that has been cut into a rectangular shape, and the other is the original material that has not been cut to obtain the cut material. There are differences between the two under different processes. When cutting through this material cutting device, the finally obtained conical piece 12 has a hypotenuse, and the shape of the conical piece 12 can be, for example, Figure 1 the triangular shape shown, or a right trapezoid with one hypotenuse. In this embodiment, the material is a carbon fiber material.

[0043] Referring to Figure 6 , four working stations are defined on the platform 21 of the frame 20. These four working stations correspond to the rotating mechanism 31 in the adhesion assembly 30. In the clockwise direction, they are the loading station 251, the hypotenuse cutting station 252, the waste discharging station 253, and the adhesion station 254 in sequence. The central angle between each of these four working stations is 90°, and they are all arranged around the second axis where the rotating mechanism 31 of the rotating conveying assembly is located. The rotating mechanism 31 rotates intermittently, and each rotation is 90°, so that a placement portion 3121 corresponds to a working station every time it stops rotating. Among them, the loading station 251 is used to place the cut material on the placement portion 3121, the hypotenuse cutting station 252 is used to cut the cut material into a conical portion and waste, the waste discharging station 253 is used to take away the waste, and the adhesion station 254 is used to take away the conical piece 12 or be linked with other devices to complete other processes. In addition, a rolling and rubbing station 255 is also defined on the frame 20, and this rolling and rubbing station 255 corresponds to the position of the rolling and rubbing assembly 50.

[0044] The negative pressure communication component 90 includes a negative pressure driving mechanism 91 and a negative pressure communication piece 92; the rotating disk 311 is provided with a plurality of second negative pressure channels corresponding to and connected with the first negative pressure channels of each of the placement blocks 312, and each of the second negative pressure channels is provided with a second negative pressure port 3111 at one end away from the corresponding placement block 312; the placement blocks 312 are uniformly arranged at a preset first angle along the circumferential interval of the rotating disk 311; the rotating disk 311 is suitable for rotating around the second axis at a preset second angle each time, and the second angle is equal to the first angle; the negative pressure driving mechanism 91 is installed on the frame 20, and the negative pressure communication piece 92 is fixedly arranged at the output end of the negative pressure driving mechanism 91, and is suitable for being connected by the negative pressure The driving mechanism 91 drives reciprocating motion along the first direction; the negative pressure connecting piece 92 is provided with a plurality of third negative pressure channels connected to the vacuum negative pressure device, and the vacuum negative pressure device independently supplies pressure for each of the third negative pressure channels; a second negative pressure port 3111 is formed at one end of each of the third negative pressure channels away from the vacuum negative pressure device; the first negative pressure port 3122 and the second negative pressure port 3111 are arranged in the same number at a preset third angle at a circumferential interval relative to the second axis, the third angle is equal to the first angle, and the negative pressure driving mechanism 91 is suitable for driving the negative pressure connecting piece 92 to move toward the rotating disk 311 so that the second negative pressure port 3111 is docked and connected with a first negative pressure port 3122 corresponding to a position.

[0045] Among them, the vacuum negative pressure device can be arranged inside the frame 20 of the molding equipment. The vacuum negative pressure device can generate negative pressure after being powered on and running, and transmit the pressure to the required position through the negative pressure pipeline, so as to realize negative pressure adsorption of the workpiece. The vacuum negative pressure device is a conventional device for realizing negative pressure adsorption in the field, and will not be described in detail here.

[0046] Placement block 312 structural reference Figure 10 , Figure 12, which is generally a cuboid-shaped member. A placement portion 3121 is formed on the upper surface of the placement portion 3121. The cut material can be placed on the placement portion 3121. When the cut material is placed on the placement portion 3121, the sticky side of the cut material faces upward and the non-sticky side faces downward. The placement block 312 is provided with a plurality of first negative pressure ports 3122 at the position of the placement portion 3121. These first negative pressure ports 3122 are arranged in a regular manner, and each first negative pressure port 3122 is designed to have a smaller size. A smaller distance is designed between adjacent first negative pressure ports 3122. With such a setting, when the cut material is placed on the placement portion 3121, the negative pressure formed by the first negative pressure ports 3122 can act on the cut material more evenly, avoiding deformation or bending of the cut material due to negative pressure adsorption. Among them, a first negative pressure channel is arranged inside the placement block 312. The first negative pressure channel can be connected to a vacuum negative pressure device through a negative pressure pipeline, so as to form a negative pressure through the vacuum negative pressure device and adsorb and fix the cut material at the position of the first negative pressure ports 3122. It should be noted that the position where the first negative pressure ports 3122 are arranged should generally correspond to the range of the conical piece 12 in the cut material, and the first negative pressure ports 3122 are not required to be arranged at the position of the waste material. The placement block 312 is provided with an ejection channel 3125 that penetrates up and down at the position corresponding to the waste material. The ejection rod 841 of the ejection mechanism 84 can move upward to eject the waste material located above the ejection channel 3125 from the placement block 312. In addition, referring to Figure 8 , a beveled edge relief groove 4153123 is recessed at the top of the placement block 312. The position of the beveled edge relief groove 4153123 corresponds to the position to be cut of the cut material, which can play a role in relieving the beveled edge cutter head 321, so that the beveled edge cutter head 321 can pass through the cut material in the up and down direction to ensure that the cut material is cut to form the conical piece 12.

[0047] In addition, referring to Figure 13 , specifically, on the surface of the placement portion 3121 of the placement block 312, an adhesion groove 3124 is provided that penetrates the upper surface of the placement block 312 in the left and right directions and is recessed downward. The shape and size of the adhesion groove 3124 are generally adapted to the shape and size of the spoke end, but the size of the adhesion groove 3124 is larger than the size of the spoke end to ensure that the spoke end can fall into the adhesion groove 3124. And, referring to Figure 8, when the conical piece 12 is placed, a part of it will straddle the adhesion groove 3124, that is, the conical piece 12 will cover above the adhesion groove 3124. However, the width of the conical piece 12 is obviously smaller than the width of the placement portion 3121. Therefore, the conical piece 12 will only cover a part of the adhesion groove 3124. With such a setting, since the position of the spoke corresponds to the adhesion groove 3124, during the downward movement of the spoke along with the displacement assembly 40, the end of the spoke will first contact the conical piece 12. Then, under the action of the spoke, the conical piece 12 deforms, and at the same time, the spoke falls into the adhesion groove 3124, and the bent and deformed part of the conical piece 12 will contact the outer surface of the end of the spoke. Designing the structure of the adhesion groove 3124 can increase the contact area between the conical piece 12 and the outer surface of the end of the spoke, thereby improving the firmness of the adhesion of the conical piece 12 to the end of the spoke. If the conical piece 12 is placed flat on the placement portion 3121 without the designed adhesion groove 3124 structure, when the end of the spoke is seated on the placement portion 3121, since the shape of the end of the spoke is generally cylindrical, only a very small part contacts the conical piece 12. In this way, even if the end of the spoke is pressed by the pressing head, the improvement of the adhesion firmness between the two is limited. In addition, more importantly, by providing the adhesion groove 3124, when the conical piece 12 is placed on the placement portion 3121, the position where it can be placed has a greater redundancy; it is easy to understand that if the adhesion groove 3124 is not provided, when the conical piece 12 is adhered, in order to prevent the extra edge of the conical piece 12 from protruding outside the end of the spoke and interfering with the subsequent adhesion process, it is necessary to ensure that the end of the spoke is seated at the straight-edge position of the conical piece 12. This requires that the placement position of the conical piece 12 needs to be extremely accurate, and at the same time, the position of the spoke in the displacement assembly 40 and the position of the displacement assembly 40 relative to the adhesion assembly 30 also need to be always consistent. This obviously puts higher requirements on the overall manufacturing accuracy of the equipment and thus increases the manufacturing cost of the equipment. In the present technical solution, the adhesion groove 3124 is provided on the placement portion 3121, and the conical piece 12 is placed straddling the adhesion groove 3124. Since the size of the adhesion groove 3124 is large, the end of the spoke can easily enter the adhesion groove 3124, and at the same time, the conical piece 12 will deform with the movement of the end of the spoke, so as to prevent the edge of the conical piece 12 from protruding outside the end of the spoke. Therefore, the conical piece 12 does not need to accurately determine the placement position, and only needs to roughly determine the part of the conical piece 12 straddling the other side of the adhesion groove 3124.

[0048] Further, referring to Figure 21, the cross-section of the adhesion groove 3124 is generally semi-circular, with a notch formed above it, and the inner groove wall is arc-shaped to fit the cylindrical spoke end. The size of the notch should be larger than the outer diameter of the spoke end to ensure that the spoke end can fall into the adhesion groove 3124. At the same time, the depth of the adhesion groove 3124 should be greater than the radius of the spoke end. That is to say, when the spoke end falls into the adhesion groove 3124, the part of the spoke end exposed outside the adhesion groove 3124 should belong to the upper side part of the spoke end, and the distance of the notch edge of the adhesion groove 3124 should be less than the maximum distance of the groove wall of the adhesion groove 3124. Such a setting makes the adhesion groove 3124 form an open structure with an inward surrounding. When the spoke end and the conical piece 12 fall into the interior of the adhesion groove 3124 together, the notch and the groove wall of the adhesion groove 3124 will apply force to the conical piece 12, causing the conical piece 12 to adhere to the outer surface of the spoke end. At the same time, due to the shape design of the notch of the adhesion groove 3124 and the toughness of the material of the conical piece 12 itself, the conical piece 12 will wrap around the spoke end. The wrapping here does not mean that the conical piece 12 completely surrounds the spoke end, but that the conical piece 12 partially covers the spoke end. For example, one side edge of the conical piece 12 is wrapped towards the other side edge and adheres to the spoke end. Such a setting enables the conical piece 12 to better wrap the spoke end and form a tighter fit after the spoke end falls into the adhesion groove 3124, further enhancing the adhesion strength and reliability. In addition, it helps to prevent the conical piece 12 from shifting during the adhesion process and ensures the accuracy of the adhesion position. Moreover, when the pressing head presses down on the spoke end, it will contact the conical piece 12 located above the spoke end, thereby adhering the conical piece 12 more firmly to the spoke end.

[0049] The rotating disk 311 is a cross-shaped plate-like member having four ends spaced 90° from each other, and four placing blocks 312 are respectively fixedly installed at one end position of the rotating disk 311. At the same time, the rotating mechanism 31 further includes a rotation driving unit 313. The rotation driving unit 313 includes a rotation motor 3131 and a rotation connecting block 3132. The rotation motor 3131 is installed below the platform 21 of the frame 20, and the rotation connecting block 3132 is disposed at the output end of the rotation motor 3131. The rotation connecting block 3132 can rotate about the second axis as the output end of the rotation motor 3131 rotates. At the same time, the rotation connecting block 3132 extends upward from below the platform 21 and is fixedly connected to the rotating mechanism 31 by bolts. In this embodiment, the number of the placing blocks 312 in the rotating mechanism 31 is four. These four placing blocks 312 are fixedly installed along the circumferential direction on the outer edge of the rotating mechanism 31, and the interval angle between the placing blocks 312, that is, the first angle, is 90 degrees. Driven by the rotation driving unit 313, the rotation angle of the rotating mechanism 31 each time, that is, the second angle, is also 90 degrees. And in the initial state, these four placing blocks 312 correspond to four workstations. After the rotation driving unit 313 makes one rotation, the corresponding placing block 312 that originally corresponded to the previous workstation will rotate to the adjacent next workstation. In this rotating mechanism 31, the vacuum adsorption method is used to fix the material, which can evenly adsorb the material on the placing portion 3121, avoiding the deformation or displacement of the material that may be caused by mechanical clamping, and improving the positioning accuracy and cutting stability. The placing blocks 312 can be independently replaced, which is convenient for maintenance and replacing placing blocks 312 with different shapes or sizes to adapt to different materials and cutting requirements. The rotating disk 311 rotates by the second angle each time, and the interval angle between the placing blocks 312 is the first angle, and the first angle and the second angle are equal, ensuring that after each rotation of the rotating disk 311, the placing blocks 312 can accurately stay at each corresponding workstation.

[0050] Refer to Figures 9 to 12, the negative pressure driving mechanism 91 is fixedly installed on the driving mounting plate 24. The main body of the negative pressure driving mechanism 91 is a cylinder, and its output end forms a negative pressure driving output end 911. The negative pressure driving output end 911 is fixedly connected to the negative pressure connecting member 92. Four third negative pressure ports 921 are provided on the negative pressure connecting member. These four third negative pressure ports 921 are arranged around the second axis of the rotating mechanism 31 at an interval of 90 degrees, and each of these four third negative pressure ports 921 is independently connected to the vacuum negative pressure device through a negative pressure pipeline. At the same time, four second negative pressure ports 3111 are provided at corresponding positions on the rotating disk 311. These four second negative pressure ports 3111 are connected to the second negative pressure channels inside the rotating disk 311. At the same time, each second negative pressure channel is connected to the first negative pressure channel of a placement block 312 through a negative pressure pipeline. In addition, two negative pressure driving sliding rods 912 extending in the up and down directions are provided on both sides of the main body of the negative pressure driving mechanism 91, which can ensure that the negative pressure driving output end 911 drives the negative pressure connecting member 92 to move in the up and down directions. When the rotating mechanism 31 is in a stopped state, the negative pressure connecting member 92 can move downward under the drive of the negative pressure driving mechanism 91, and each third negative pressure port 921 is connected to a corresponding second negative pressure port 3111 in butt joint. Before the rotating disk 311 rotates, the negative pressure connecting member 92 moves upward under the drive of the negative pressure driving mechanism 91, and the third negative pressure port 921 leaves the corresponding second negative pressure port 3111. When the rotating disk 311 rotates 90 degrees to reach the next position, the negative pressure connecting member 92 can move downward under the drive of the negative pressure driving mechanism 91 and make the third negative pressure port 921 reconnect to a corresponding second negative pressure port 3111 in butt joint. Among them, in order to ensure the sealing effect of the butt joint connection, a sealing ring is provided on the negative pressure connecting member 92 corresponding to each third negative pressure port 921. When the negative pressure connecting member 92 moves downward until the third negative pressure port 921 is connected to the second negative pressure port 3111 in butt joint, the sealing ring will be squeezed by the upper surface of the rotating disk 311, so as to seal the gap between the third negative pressure port 921 and the second negative pressure port 3111. Through the negative pressure connection assembly 90, independent control and distribution of the vacuum negative pressure for multiple placement blocks 312 are realized. The first negative pressure port 3122 of each placement block 312 is connected to the vacuum negative pressure device through independent second and third negative pressure channels, ensuring that the vacuum adsorption effect of each station is not affected by other stations and improving the reliability and stability of the vacuum adsorption. The cooperation between the negative pressure driving mechanism 91 and the negative pressure connecting member 92 can accurately control the application and disconnection of the negative pressure, so as to work in coordination with the movement of the rotating disk 311. When the rotating disk 311 rotates, the negative pressure connecting member 92 moves upward to separate the second negative pressure port 3111 and the third negative pressure port 921. After the rotating disk 311 rotates to the position and stops, the negative pressure connecting member 92 moves downward to connect the third negative pressure port 921 to the next second negative pressure port 3111 on the rotating disk 311 in butt joint.Through the negative pressure connection assembly 90, in the equipment adopting the rotating disk 311, the problem of difficult layout of the negative pressure pipeline caused by the rotation of the rotating disk 311 can be solved, and the layout problem of the negative pressure pipeline is greatly simplified.

[0051] Referring to Figure 12 , a waste discharging driving mechanism 83 is provided in the waste discharging assembly 80. In this embodiment, the waste discharging driving mechanism 83 adopts a cylinder device, which is fixedly installed on the support rod of the above-mentioned driving mounting plate 24 to form a fixed connection relationship with the frame 20. At the same time, the output end of the waste discharging driving mechanism 83 forms a waste discharging driving output end 82. A waste discharging suction head 81 is fixedly installed on the waste discharging driving output end 82. The waste discharging suction head 81 is communicated with a vacuum negative pressure device, and the waste on the placing part 3121 can be adsorbed by the negative pressure adsorption method. Among them, the waste discharging driving output end 82 is set to reciprocate in the left-right direction, so as to drive the waste discharging suction head 81 to reciprocate in the left-right direction, and the position of the waste discharging suction head 81 in the up-down direction is slightly higher than the position of the placing part 3121 to avoid interference between the waste discharging suction head 81 and the placing block 312. In the ejecting mechanism 84 in the waste discharging assembly 80, the ejecting driving cylinder 842 is fixedly installed on the platform 21, and an ejecting rod 841 is fixedly provided at the output end of the ejecting driving cylinder 842. The ejecting driving cylinder 842 can drive the ejecting rod 841 to move up or down. When the placing block 312 moves to directly above the ejecting mechanism 84, the ejecting rod 841 can move upward into the ejecting channel 3125 of the placing block 312 to eject the waste from the placing block 312. At the same time, the waste discharging suction head 81 moves above the waste, and the waste is adsorbed onto the waste discharging suction head 81 by negative pressure. Then the ejecting rod 841 moves downward to leave the ejecting channel 3125, and at the same time the waste discharging suction head 81 moves away from the placing block 312 to reach the waste disposal position. At the waste disposal position, the waste discharging suction head 81 disconnects the negative pressure, and the waste falls from the waste discharging suction head 81 to the waste disposal position. The platform 21 can be provided with an opening at the waste disposal position, and a waste collection bucket can be provided below the opening to collect the waste.

[0052] Referring to Figure 7 and Figure 8, the bevel cutting mechanism 32 is arranged at the bevel cutting station 252 of the frame 20, and is provided with a bevel cutter head 321 which can reciprocate in the third direction to cut the cutting material into a conical sheet 12 with a bevel. The third direction is inclined to the front-back direction so that the bevel cutter head 321 can cut the cutting material obliquely. The feeding and cutting mechanism 33 is arranged at the feeding station 251 of the frame 20, and is provided with a feeding cutter head 331 which can reciprocate in the left-right direction to cut the raw material into the cutting material. Before being cut by the feeding cutter head 331, part of the raw material has been placed on the placing part 3121. After being cut by the feeding cutter head 331, the part originally placed on the placing part 3121 forms the cutting material, and the remaining part of the raw material can be used continuously in the next feeding and cutting. The feeding and cutting mechanism 33 is arranged at the feeding station 251 and has a feeding cutter head 331 which can cut the raw material along the second direction to obtain the cutting material placed on the placing part 3121. Through the feeding and cutting mechanism 33, the automatic cutting and feeding of the raw material can be realized, the automation degree is further improved, and at the same time, the accurate cutting of the raw material is ensured, and the cutting material suitable for subsequent bevel cutting can be obtained.

[0053] Specifically, referring to Figure 14, the hypotenuse cutting mechanism 32 and the feeding and cutting mechanism 33 have the same structure. Among them, the cutting movement unit 322 includes a cutting bracket 324, which is fixedly installed on the platform 21. The cutting drive cylinder 3221 of the cutting movement unit 322 is installed on the cutting bracket 324, and the output end of the cutting drive cylinder 3221 can reciprocate in the up and down direction; the cutting unit 323 is installed on the output end of the cutting drive cylinder 3221. The cutting unit 323 includes a tool head drive cylinder 3231, and the output end of the tool head drive cylinder 3231 can reciprocate in the left and right direction. At the same time, a tool head is installed at the output end of the tool head drive cylinder 3231. According to whether it is applied to the hypotenuse cutting assembly or the feeding and cutting assembly, the tool head is respectively the hypotenuse tool head 321 and the feeding tool head 331. When cutting, the cutting movement unit 322 first lifts the cutting unit 323 to make the tool head away from the rotating mechanism 31. At the same time, the cutting unit 323 drives the tool head to the initial cutting position. When the rotating mechanism 31 rotates to make the placement part 3121 reach below the tool head, the cutting movement unit 322 drives the cutting unit 323 to move downwards so that the tool head contacts the cutting material on the placement part 3121. Then the cutting unit 323 drives the tool head to move horizontally. The tool head in the hypotenuse cutting assembly will also enter the hypotenuse relief groove 4153123, so as to cut off the original material or the cut material. The power sources of the cutting movement unit 322 and the cutting unit 323 can both come from the vacuum negative pressure device. The hypotenuse cutting mechanism 32 and the feeding and cutting mechanism 33 adopt the same modular components. Both of them include a cutting movement unit 322 and a cutting unit 323. The cooperation of the cutting movement unit 322 and the cutting unit 323 can realize the precise movement control of the tool head in the up and down direction and the horizontal direction. When cutting each time, the tool head can be first moved down to the cutting material, then horizontally moved to cut off the cutting material, and then lifted up to avoid interfering with the normal operation of the rotating and conveying assembly.

[0054] The pressing component 70 is introduced as follows.

[0055] Refer to Figures 7 to 11, the pressing assembly 70 includes a bevel pressing mechanism 71, a feeding pressing mechanism 72, and an adhesion pressing mechanism 73; the bevel pressing mechanism 71 is installed on the frame 20 and corresponds to the bevel cutting station 252, and is provided with a bevel pressing head 711 adapted to reciprocate in the vertical direction; the bevel pressing head 711 is adapted to press or release the cutting material on the corresponding placing portion 3121, and is provided with a bevel cutting groove 712 extending in the third direction and penetrating up and down, and the position of the bevel cutting groove 712 corresponds to the position where the cutting material on the corresponding placing portion 3121 needs to form a bevel; the bevel cutter head 321 is adapted to extend into the bevel cutting groove 712 and move along the bevel cutting groove 712; the feeding pressing mechanism 72 is installed on the frame 20 and corresponds to the feeding station 251, and is provided with a feeding pressing head 721 adapted to reciprocate in the vertical direction; the feeding pressing head 721 is adapted to press or release the cutting material on the corresponding placing portion 3121; the adhesion pressing mechanism 73 is installed on the frame 20 and corresponds to the adhesion station 254, and is provided with an adhesion pressing head 731 adapted to reciprocate in the vertical direction; the adhesion pressing head 731 is adapted to move downward and press the spoke after the spoke adheres to the conical piece 12.

[0056] Referring to Figure 9 , both the bevel pressing head 711 and the feeding pressing head 721 are block-shaped members, which can move up and down driven by the bevel pressing mechanism 71 and the feeding pressing mechanism 72, and press the cutting material located on the placing portion 3121 when moving downward. Among them, both the bevel pressing mechanism 71 and the feeding pressing mechanism 72 are installed on the driving mounting plate 24 of the frame 20, and both include a pressing driving cylinder 74, a pressing sliding rod 75, and a pressing transfer plate 76. The difference between the two is that the bevel pressing mechanism 71 corresponds to the placing portion 3121 of the bevel cutting station 252, and the feeding pressing mechanism 72 corresponds to the placing portion 3121 of the feeding station 251. The pressing driving cylinder 74 is fixedly installed on the driving mounting plate 24, and the output end of the pressing driving mechanism is located below the driving mounting plate 24 and can reciprocate in the vertical direction. A pressing transfer plate 76 is fixedly connected to the output end by bolts, and both the bevel pressing head 711 and the feeding pressing head 721 are fixedly connected to the corresponding pressing transfer plate 76 by bolts. In addition, two pressing sliding rods 75 are provided in the pressing driving mechanism, and the two pressing sliding rods 75 are slidably connected to the driving mounting plate 24 in the vertical direction, that is, under the restriction of the driving mounting plate 24, the two pressing sliding rods 75 can only move in the vertical direction. The two pressing sliding rods 75 are fixedly connected to the pressing transfer plate 76, so as to restrict the bevel pressing head 711 and the feeding pressing head 721 to only move in the vertical direction, ensuring the accuracy of the movement routes of the bevel pressing head 711 and the feeding pressing head 721.

[0057] In addition, referring toFigure 9 On the hypotenuse pressing head 711, there is also a hypotenuse cutting groove 712 corresponding to the position of the hypotenuse relief groove 4153123 on the corresponding placement block 312. The hypotenuse cutting groove 712 penetrates the hypotenuse pressing head 711 in the up and down direction, and its end facing the hypotenuse cutting component is open. The hypotenuse cutting head 321 in the hypotenuse cutting component will extend into the hypotenuse cutting groove 712 to ensure the accurate cutting position of the cut material. The pressing component 70 is provided, and the pressing component 70 includes a hypotenuse pressing mechanism 71 and a feeding pressing mechanism 72. Both of these pressing mechanisms can firmly press the cut material on the placement part 3121 during the cutting process, preventing the material from moving or deforming due to the contact between the cutting head and the material and the movement during cutting, ensuring the cutting accuracy and the accuracy of the hypotenuse shape. At the same time, a hypotenuse cutting groove 712 is provided on the hypotenuse pressing head 711 of the hypotenuse pressing mechanism 71. The hypotenuse cutting groove 712 provides guidance for the hypotenuse cutting head 321, enabling the hypotenuse cutting head 321 to cut along a predetermined trajectory, further improving the accuracy and quality of the hypotenuse cutting.

[0058] Refer to Figure 10 The adhesion pressing head 731 is a block-shaped component, which can move up and down under the drive of the pressing drive mechanism, and press the end of the spoke when moving down, and then move up to enable the spoke to leave the adhesion station 254. The pressing drive mechanism can drive the adhesion pressing head 731 to reciprocate in the first direction, realizing the active control of the pressing force on the conical piece 12. Compared with only relying on gravity to press, the pressing drive mechanism can provide a more stable and controllable pressing force, ensuring full contact between the conical piece 12 and the end of the spoke, significantly improving the firmness and consistency of adhesion. At the same time, the active control of the pressing force also enables the equipment to adapt to conical pieces 12 of different materials or sizes, improving the versatility of the equipment.

[0059] Next, the feeding component 60 will be introduced.

[0060] Refer to Figure 7 、 Figure 8 and Figure 18, The feeding assembly 60 is installed on the frame 20 and corresponds to the loading station 251. It includes a feeding moving mechanism 61 and a pressing mechanism 62. The feeding moving mechanism 61 is provided with a material bearing part 611 adapted to carry the original material, and the material bearing part 611 is adapted to reciprocate in a fifth direction perpendicular to and horizontal to the fourth direction. The pressing mechanism 62 is installed on the feeding moving mechanism 61 to move along the fifth direction with the material bearing part 611. It is provided with a pressing part 621 facing the material bearing part 611, and the pressing part 621 is adapted to reciprocate in the up and down direction to press or release the original material located on the material bearing part 611. The feeding mechanism is configured to move a preset distance towards the placing part 3121 located at the loading station 251 after the pressing part 621 presses the original material located on the material bearing part 611, so as to lay the end part of the original material flat on the placing part 3121. The loading and cutting assembly is configured to cut off the original material after the end part of the original material is laid flat on the corresponding placing part 3121.

[0061] In addition, the feeding assembly 60 further includes a rolling mechanism 63. The original material adheres to the release film to form a composite film roll. The rolling mechanism 63 includes a loading roll shaft 631 and a recycling roll shaft 632. The loading roll shaft 631 is used to sleeved with the composite film roll, and the recycling roll shaft 632 is used to wind the release film. The original material and the release film are peeled off when the composite film roll passes through the feeding moving mechanism 61 and the pressing mechanism 62. The recycling roll shaft 632 is configured to rotate synchronously to wind and recycle the release film when the feeding moving mechanism 61 and the pressing mechanism 62 cooperate to clamp the original material and move towards the corresponding placing part 3121.

[0062] Specifically, referring to Figure 7 and Figure 8 , the feeding assembly 60 can conveniently and accurately transport the original material onto the placing part 3121 of the loading station 251. Among them, when using the feeding assembly 60, the original material is attached to the release film to form a composite film roll. The form of the composite film roll can conveniently store the original material and avoid soiling of the original material. Referring to Figure 18, in the rolling mechanism 63 of the feeding component 60, there is a rolling bracket 633. The rolling bracket 633 is fixedly installed on the platform 21 of the frame 20. At the same time, an upper feeding rolling shaft 631, a rolling driving motor 634, a first guiding shaft 635 and a second guiding shaft 636 are installed on the rolling bracket 633. The axial directions of the above-mentioned shafts are all in the left-right direction, that is, the same as the cutting direction of the upper feeding and cutting component. The recycling rolling shaft 632 is arranged at the output end of the rolling driving motor 634. Through the rolling driving motor 634, the recycling rolling shaft 632 can rotate automatically, and its rotation axis also extends in the left-right direction. The first guiding shaft 635 and the second guiding shaft 636 are arranged in front of the upper feeding rolling shaft 631. The first guiding shaft 635 and the second guiding shaft 636 are symmetrically arranged in the up-down direction. A groove-like structure is formed on the side wall of the first guiding shaft 635. The width of the composite film roll is the same as the inner wall width of the groove-like structure. At the same time, the second guiding shaft 636 is located above the first guiding shaft 635 and can extend into the groove-like structure formed by the side wall of the first guiding shaft 635, so as to press the composite film roll against the side wall of the first guiding shaft 635, playing a role in guiding the forward conveying of the composite film roll.

[0063] Refer to Figure 18, a feeding and moving mechanism 61 and a material pressing mechanism 62 are provided at the front position of the rolling mechanism 63. The feeding and moving mechanism 61 includes a feeding driving cylinder 612 fixedly installed on the platform 21. The output end of the feeding driving cylinder 612 can reciprocate in the front-back direction and is fixedly provided with a material supporting block 613. The upper side surface of the material supporting block 613 is provided with a material supporting portion 611. The material supporting portion 611 is a sunken groove extending in the front-back direction. The front and rear ends of the sunken groove are open, and the width of the sunken groove in the left-right direction is the same as the width of the original material. At the front end position of the material supporting block 613, a return shaft 614 is further provided. The return shaft 614 is used to pull the release film peeled from the original material back to the recovery reel 632. The material pressing mechanism 62 includes a material pressing driving cylinder 622 fixedly installed on the material supporting block 613. The output end of the material pressing driving cylinder 622 can reciprocate in the up-down direction and is fixedly provided with a material pressing block 623. The material pressing block 623 is provided with a material pressing portion 621 facing the material supporting portion 611. The material pressing portion 621 can extend into the material supporting portion 611 and its width in the left-right direction is adapted to the width of the material supporting portion 611. During feeding, the composite film roll is sleeved on the loading reel 631, and the composite film roll passes through the first guiding shaft 635 and the second guiding shaft 636, and then the composite film roll is guided to the positions of the feeding and moving mechanism 61 and the material pressing mechanism 62. At this time, the original material and the release film in the composite film roll are peeled off. The release film is located above and is guided to the return shaft 614 and then wound onto the recovery reel 632. The original material is placed in the material supporting portion 611 and passes through the gap between the material supporting portion 611 and the material pressing portion 621, and the original material extends out from the front end of the material supporting portion 611. Then the material pressing portion 621 presses the original material, and the feeding and moving mechanism 61 drives the material supporting block 613 to move forward a preset distance. The preset distance is the size of the cutting material in the front-back direction when it is at the loading station 251. At this time, the end of the original material will be placed on the placing portion 3121. Then the loading and cutting assembly operates to cut off the end of the original material, and the part on the placing portion 3121 can form the cutting material. Then the material pressing portion 621 is lifted, and the feeding and moving mechanism 61 retracts. At this time, since the recovery reel 632 pulls the composite film roll, the original material will not retract with the feeding and moving mechanism 61.

[0064] The feeding assembly 60 can realize automatic feeding and positioning of the original material, making the entire loading process fully automated; wherein, the feeding assembly 60 can ensure the size accuracy of the cut material itself and the accuracy of the placement position of the cut material on the placement portion 3121; specifically, the relative position of the feeding assembly 60 and the placement portion 3121 of the loading station 251 is determined, which ensures that the position of the cut material on the placement portion 3121 along the first direction can be guaranteed to be accurate, and at the same time, the feeding moving mechanism 61 in the feeding assembly 60 moves a predetermined preset distance toward the placement portion 3121 each time, which can move the cut material forward along the third direction by a fixed distance, so that the end of the original material with a determined length is placed on the placement portion 3121, and then the original material is cut by the loading and cutting assembly, so that the accuracy of the size and position of the cut material on the placement portion 3121 can be guaranteed, thereby improving the accuracy of the cutting position of the cut material by the bevel cutting assembly in the bevel cutting station 252. In addition, the original material is adhered to the release film to form a composite film roll. The shape of the composite film roll can facilitate the storage of the original material and avoid contamination. At the same time, the composite film roll can be conveniently mounted on the loading rolling shaft 631 of the rolling mechanism 63. When the composite film roll passes through the feeding moving mechanism 61 and the pressing mechanism 62, the original material and the release film are peeled off, and the recovery rolling shaft 632 rotates synchronously to recover the release film, thereby realizing the automatic separation of the material and the release film and the automatic recovery of the release film. It can also cooperate with the feeding moving mechanism 61 and the pressing mechanism 62 in the feeding assembly 60, and each mechanism works together during each loading to realize efficient and accurate loading of the original material.

The sliding groove 416 is used for the accommodating seat 412 to adjust its position in the left-right direction, and the relief groove 415 is used to make way for the clamping mechanism 44, so that the clamping mechanism 44 can enter the position corresponding to the accommodating seat 412 to clamp and fix the spoke. A plurality of through holes are also provided at certain intervals in the left-right direction on the sliding groove 416, and these through holes are used for bolts to pass through to form a detachable fixed connection relationship with the accommodating seat 412.

[0072] There are two receiving seats 412, and the two receiving seats 412 are arranged on the fixed seat 414 in the left-right direction. The shape of the receiving seat 412 is generally in the shape of a lying "L", the long side thereof extends in the left-right direction, and a mating protrusion 417 extending in the left-right direction is provided at the bottom. The size of the mating protrusion 417 is adapted to the size of the sliding groove 416 on the fixed seat 414, so that the receiving seat 412 can adjust its position in the left-right direction under the limitation of the sliding groove 416 of the fixed seat 414; at the same time, a long strip-shaped through hole extending in the left-right direction is also provided on the long side of the receiving seat 412 corresponding to the through hole on the sliding groove 416. When fixing the receiving seat 412, the bolt can be passed through the through hole of the fixed seat 414 and penetrate the through hole on the fixed seat 414, and then the bolt can be tightened. When adjusting the position of the receiving seat 412 in the left-right direction, the bolt can be loosened and then the position of the receiving seat 412 can be adjusted. The short side of the receiving seat 412 extends in the up-down direction, and a positioning groove 413 extending in the left-right direction and opening upward is provided. The positions of the two positioning grooves 413 of the two receiving seats 412 correspond to each other and jointly form the receiving groove 411 of the receiving mechanism 41. When the spoke is placed in the receiving groove 411, the two ends in the length direction of the spoke will be respectively placed in the two positioning grooves 413 of the two receiving seats 412, and the middle part thereof will be suspended, and the clamping mechanism 44 located in the middle position can clamp and fix the spoke. Among them, referring to Figure 5 , the positioning groove 413 can be designed as a structure with a variable groove width. Specifically, the positioning groove 413 can be divided into two sections with different groove widths in the left-right direction. The groove width of the part closer to the inside is larger than the groove width of the part closer to the outside, and the groove width of the inside is adapted to the outer diameter of the connecting cap 11, and the groove width of the outside is adapted to the outer diameter of the end of the spoke body 10. Through the differential design of the groove width of the positioning groove 413, when the spoke is placed on the receiving groove 411, the positions of its two ends will be predetermined within a general range by the position of the connecting cap 11, so as to more conveniently position the spoke at an accurate position in the receiving groove 411.

[0073] The clamping mechanism 44 includes a clamping driving unit 441 and a clamping block 442. The clamping driving unit 441 can be a cylinder or an electric cylinder, and it includes two output ends. The two output ends are respectively connected to a clamping block 442, and the two output ends can drive the two clamping blocks 442 to move towards or away from each other in the front-rear direction. When the two clamping blocks 442 move towards each other, the spoke can be clamped and fixed, and when they move away from each other, the spoke can be released. Among them, referring to Figure 17, the clamping mechanism 44 is fixedly installed on the fixed seat 414 by bolts to maintain the relative fixation of the positions between the clamping block 442 and the fixed seat 414. At the same time, the clamping block 442 of the clamping mechanism 44 protrudes upward from the position of the relief groove 415 of the fixed seat 414, and its position in the up and down direction is adapted to the position of the receiving groove 411, so as to be adapted to the position of the spoke after the spoke is placed in the receiving groove 411. When fixing the spoke, the spoke can be first placed in the receiving groove 411, and then the clamping block 442 of the clamping mechanism 44 clamps the spoke, so that the spoke is fixed. The clamping mechanism 44 is arranged between the two receiving seats 412. The clamping drive unit 441 in the clamping mechanism 44 can drive the two clamping blocks 442 to move, so as to clamp or release the spoke placed in the receiving groove 411. Through the clamping mechanism 44, the spoke can be clamped after being placed in the receiving groove 411, so that the spoke will not rotate or translate during the coiling process, preventing the winding accuracy from being affected due to the loosening of the spoke during the coiling process. In addition, during the process of the spoke adhering to the conical piece 12, the clamping mechanism 44 can also fix the spoke, ensuring that the second displacement mechanism 43 can smoothly drive the spoke to move downward and adhere to the conical piece 12.

[0074] Referring to Figure 19 and Figure 20 , during adhesion, the conical piece 12 is laid flat on the placing part 3121, and at the same time, the spoke is placed in the receiving groove 411. At this time, the end of the spoke is exposed in the left and right directions, and under the action of the second displacement mechanism 43, the spoke is located at a higher position, and the spoke will not interfere with the adhesion assembly 30 when placing the spoke; then the second displacement mechanism 43 drives the spoke to move downward, so that the spoke can fall onto the placing part 3121 and adhere to the conical piece 12, but at this time the spoke is only adhered to the conical piece 12 under the action of gravity, and the adhesion degree between the two is not firm enough; then the adhesion pressing head 731 moves downward, and the pressing head can press the end of the spoke after the end of the spoke adheres to the conical piece 12, so that the end of the spoke can firmly adhere to the conical piece 12; after the adhesion pressing head 731 presses the end of the spoke, the adhesion pressing head 731 moves upward, and then the second displacement mechanism 43 drives the spoke to move upward, and the conical piece 12 is taken away from the placing part 3121 together with the spoke.

[0075] Next, the coiling assembly 50 will be introduced.

[0076] Referring to Figure 5 , Figure 15 , Figure 16The rolling assembly 50 includes a rotary drive mechanism 51 and at least one rolling mechanism 52; the output end of the rotary drive mechanism 51 is connected to the rolling mechanism 52, and drives the rolling mechanism 52 to rotate around a first axis in a first direction; the rolling mechanism 52 includes a radial drive unit 521 and at least two rolling members 522, and the rolling members 522 correspond to the rolling stations 255; the output end of the radial drive unit 521 is connected to each of the rolling members 522, and drives each of the rolling members 522 to move toward or away from each other in the radial direction relative to the first direction; wherein, after the conical piece 12 is attached to the end through the displacement assembly 40 After the spoke moves to the winding station 255, the end of the spoke moves in the up and down direction through the second displacement mechanism 43 to enter between the winding members 522 of the winding mechanism 52, and during the movement, the conical piece 12 is contacted with at least one of the winding members 522 and bent toward the winding direction of the conical piece 12; the radial driving unit 521 is suitable for driving the winding members 522 to move toward each other until they contact the end of the spoke located between the winding members 522, and drive the winding mechanism 52 to rotate through the rotary driving mechanism 51, so as to wind the conical piece 12 into the tapered section.

[0077] In this embodiment, each of the rolling mechanisms 52 includes two rolling members 522; the two rolling members 522 belonging to the same rolling mechanism 52 are arranged symmetrically along the radial direction relative to the first direction, and the surfaces of the two rolling members 522 facing each other form a first rolling surface 523 and a second rolling surface 524, respectively, and the first rolling surface 523 and the second rolling surface 524 are both planes perpendicular to the radial direction; at least one of the first rolling surface 523 and the second rolling surface 524 is recessed with a yielding portion 525; the yielding portion 525 extends to the edge of the rolling member 522 to yield the spokes and the conical sheet 12, and includes a circular groove 526 corresponding to the end shape of the spoke and a flat groove 527 corresponding to the conical sheet 12. Further, the yielding portion 525 is provided in both the first rolling surface 523 and the second rolling surface 524, and the two yielding portions 525 of the two are arranged diagonally relative to the first axis.

[0078] Specifically, refer to Figure 15 and Figure 16, the rolling component 50 mainly includes a rotation driving mechanism 51 and a rolling mechanism 52. In this embodiment, corresponding to the displacement component 40 located at the middle position, two rolling mechanisms 52 are arranged in the left-right direction and are respectively used for winding the conical pieces 12 attached to both ends of the spoke in the left-right direction. Among them, the rotation driving mechanism 51 can be a driving motor, and the number of driving motors can be set to two corresponding to the two rolling mechanisms 52. Each rolling mechanism 52 is connected to the output end of a driving motor, so that the rolling mechanism 52 can be driven by the driving motor to rotate around the first axis. The driving motor is also fixedly installed on the platform 21 of the frame 20 through a plate-shaped member, so as to drive itself to adjust its position in the left-right direction through the movement of the platform 21 in the left-right direction.

[0079] Each of the rolling mechanisms 52 includes a radial driving unit 521 and at least two rolling members 522. In this embodiment, the number of rolling members 522 is two. The radial driving unit 521 can be a cylinder or an electric cylinder, and it has output ends corresponding to the number of rolling members 522. For example, when the number of rolling members 522 is two, the number of output ends of the radial driving unit 521 is also two. The output ends of the radial driving unit 521 can reciprocate in the radial direction relative to the first axis, and it can adopt the conventional cylinder or electric cylinder driving mechanism in the art, which will not be elaborated here.

[0080] Referring to Figure 22 , the rolling member 522 is generally a block-shaped member in the shape of a cuboid, on which threaded through holes can be provided and it is connected to the output end of the radial driving unit 521 through bolts or other fittings. A rolling surface is formed on one side of the rolling member 522, and the rolling surfaces on the two rolling members 522 face each other and respectively form a first rolling surface 523 and a second rolling surface 524. Taking the first rolling surface 523 among them as an example, referring to Figure 6A recessed portion 525 is provided on the first rolling surface 523. The recessed portion 525 is located in the middle and lower part of the first rolling surface 523 and includes a circular groove 526 and a flat groove 527. The circular groove 526 is located in the middle of the vertical direction and extends to the edge of the rolling member 522 in the left-right direction, so as to make way for the end of the spoke. The flat groove 527 is provided below the circular groove 526 and is a shallow and flat recessed structure. The upper edge of the recessed portion is the same edge as the lower edge of the circular groove 526 and the flat groove 527 also extends to the edge of the rolling member 522 in the left-right direction. A winding space 53 is formed between the two winding members 522, and the end of the spoke enters the winding space 53, and the end of the spoke body 10 corresponds to the position of the circular groove 526, and the position of the conical piece 12 corresponds to the position of the flat groove 527, so as to facilitate winding the conical piece 12 to the end of the spoke body 10. In addition, a yielding portion 525 is also provided on the second winding surface 524 of the other winding member 522, but this yielding portion 525 is arranged diagonally with the yielding portion 525 on the first winding surface 523, that is, when the yielding portion 525 on the first winding surface 523 is located at a lower position, the yielding portion 525 on the second winding surface 524 is located at an upper position. A clearance portion 525 is provided on the rolling surface of the rolling element 522. The recessed structure of the clearance portion 525 allows the spokes and the conical piece 12 to be accommodated in the clearance portion 525, so that the first rolling surface 523 and the second rolling surface 524 of the two rolling elements 522 can contact each other, so that the rolling element 522 can contact the spokes more closely, and avoid the conical piece 12 from wrinkling during the rolling process due to the excessive gap between the rolling element 522 and the spokes. At the same time, the design of the circular groove 526 and the flat groove 527 respectively plays a positioning role for the end of the spoke and the conical piece 12, ensuring that the conical piece 12 can be accurately wound on the end of the spoke.The relief portions 525 on the two rolling members 522 are arranged diagonally. When the relief portion 525 of one rolling member 522 contacts the spoke, the rolling surface of the other rolling member 522 will fit flatly on the spoke, thus avoiding insufficient close contact between the rolling member 522 and the spoke due to the overly large space of the relief portion 525. At the same time, since the rolling mechanism 52 rotates, it is impossible to determine which one of the two rolling members 522 is in the correct position during the rolling process. Under the action of the lifting mechanism, the tapered piece 12 will bend towards the winding direction. At this time, it is necessary to ensure that a relief portion 525 will contact the tapered piece 12 and the end of the spoke in the opposite direction of the bending of the tapered piece 12. By arranging the relief portions 525 on the two rolling members 522 diagonally, no matter what position the rolling mechanism 52 rotates to, as long as the positional relationship between the two rolling members 522 forms a space for the spoke to enter from the up and down directions, it can be ensured that a relief portion 525 will contact the tapered piece 12 and the end of the spoke, so that the tapered piece 12 can be accurately wound around the end of the spoke.

[0081] The spoke end taper section forming equipment involved in this embodiment mainly includes a frame 20, an adhesion assembly 30, a displacement assembly 40, and a rolling assembly 50. This forming equipment can automatically wind the tapered piece 12 around the end of the spoke to form a taper section, which can effectively improve production efficiency and reduce labor costs.

[0082] Among them, the adhesion component 30 is provided with a placement part 3121, and the conical sheet 12 can be laid flat on the placement part 3121; the displacement component 40 is provided with a receiving groove 411, a first displacement mechanism 42 and a second displacement mechanism 43. The receiving groove 411 can be used to receive the spoke, and when the spoke is placed in the receiving groove 411, the end of the spoke can be exposed from the receiving groove 411 in the first direction, so as to facilitate winding the conical sheet 12 around the exposed end of the spoke subsequently. The first displacement mechanism 42 can drive the spoke to move between the adhesion station 254 and the rubbing and winding station 255. After the conical sheet 12 is adhered to the end at the adhesion station 254, the spoke can be driven by the first displacement mechanism 42 to move to the rubbing and winding station 255, and the conical sheet 12 can be wound around the end by the rubbing and winding component 50; the second displacement mechanism 43 can drive the spoke to move up and down at the adhesion station 254, so that the spoke is seated on the conical sheet 12 and adheres to the conical sheet 12. When performing adhesion, first place the conical sheet 12 flat on the placement part 3121 of the adhesion component 30, then place the spoke in the receiving groove 411 of the displacement component 40 and expose the end of the spoke. At this time, the second displacement mechanism 43 of the displacement component 40 keeps the spoke at a higher position to avoid interference between the spoke and the adhesion component 30 when placing the spoke; then the second displacement mechanism 43 drives the spoke to move downward so that the spoke can be seated on the placement part 3121 and adhere to the conical sheet 12. After the adhesion is completed, the second displacement mechanism 43 lifts the spoke to take the conical sheet 12 away from the placement part 3121, and then the first displacement mechanism 42 drives the spoke to move along the second direction to the rubbing and winding station 255.

[0083] The curling assembly 50 includes a rotary drive mechanism 51 and at least one curling mechanism 52. The curling mechanism 52 can rotate around the first axis under the action of the rotary drive mechanism 51. At the same time, the curling mechanism 52 includes a radial drive unit 521 and curling members 522. The radial drive unit 521 can drive multiple curling members 522 to move closer to or away from each other radially simultaneously or asynchronously. When these curling members 522 move away from each other, a curling space 53 will be formed between these curling members 522. The end of the spoke can be moved to the curling space 53. Then, these curling members 522 move closer to each other under the action of the radial drive unit 521 and contact the end of the spoke. Then, the rotary drive mechanism 51 drives the curling mechanism 52 to rotate, and at the same time, these curling members 522 will also rotate accordingly. During the rotation of the curling members 522, the curling members 522 will apply pressure to the conical piece 12, causing the conical piece 12 to deform. At the same time, the conical piece 12 will be pressed against the side wall of the end of the spoke. As the curling mechanism 52 rotates, the curling members 522 will rotate around the end of the spoke for one or more turns until the conical piece 12 is completely attached to the end of the spoke and a tapered section is formed. Through the curling assembly 50, the conical piece 12 can be accurately and efficiently wound into a tapered section surrounding the end of the spoke, and the rotary drive mechanism 51 and the curling mechanism 52 in the curling assembly 50 cooperate with each other to realize the curling action of the conical piece 12.

[0084] In addition, the conical piece 12 attached to the end of the spoke is in an unfolded state before curling, and only one side of it is attached to the end of the spoke. When the spoke is placed in the receiving groove 411, the unfolding and laying direction of the conical piece 12 may have different directions. However, during curling, it is necessary to ensure that the conical piece 12 can contact the curling members 522 in the correct way to prevent the conical piece 12 from being wrinkled or deformed due to the extrusion of the curling members 522. At the same time, this extrusion will also lead to the failure of curling the conical piece 12. Therefore, the second displacement mechanism 43 not only functions to make the spoke sit on the placing portion 3121 at the adhesion station 254, but also drives the spoke to move upward during the process of the spoke entering the position to be curled. Through this action and the position coordination with the curling members 522, the conical piece 12 can contact the curling members 522, and by setting a definite moving direction, the conical piece 12 can be bent in the direction towards its winding direction. At this time, the conical piece 12 will always maintain contact with the curling members 522. Then, the curling members 522 move closer to each other and contact the end of the spoke. Then, by rotating the curling mechanism 52 in the correct direction, the conical piece 12 can be wound around the end of the spoke in the correct way.

[0085] Embodiment 2 Embodiment 2 is based on Embodiment 1. The difference between it and Embodiment 1 is that the rolling member 522 in the rolling mechanism 52 is set as a roller 528. Each of the rollers 528 rotates around a third axis in the first direction, and the conical piece 12 is wound around the end of the spoke through the circumferential surface 529 of each roller 528 to form the tapered section.

[0086] Specifically, referring to Figure 23 and Figure 24 In this embodiment, the number of the rolling members 522 is two, and the output end of the radial driving unit 521 in the rolling mechanism 52 can drive the two rolling members 522 to move towards or away from each other in the radial direction relative to the first axis. When the rolling member 522 is set as a roller 528, the shaft rod of the roller 528 is directly fixed on the output end of the radial driving unit 521, and at the same time, the roller 528 can freely rotate around the third axis where its shaft rod is located. The outer peripheral side of the roller 528 is a circumferential surface 529 with a certain width. During rolling, the circumferential surface 529 of the roller 528 will contact the end of the spoke. By designing the rolling member 522 as a roller 528, during the rolling process, the roller 528 will also rotate around the second axis. While the roller 528 is rotating, its circumferential surface 529 will always be in contact with the end of the spoke along the length direction of the spoke, and the sliding friction can be changed into rolling friction, significantly reducing the friction force between the rolling member 522 and the conical piece 12. The smaller friction force makes the winding process smoother, reduces the wear of the conical piece 12 caused by excessive friction, improves the winding efficiency, and at the same time ensures the integrity of the conical piece 12. Compared with the structure of the rolling member 522 in Embodiment 1, the rolling member 522 with the structure of the roller 528 is simpler in structure and lower in part cost. At the same time, as long as the conical piece 12 can correctly contact the circumferential surface 529 of the roller 528 in the lifting mechanism, the roller 528 can better complete the rolling process, effectively improving the rolling quality of the conical piece 12. Among them, the width of the circumferential surface 529 of the roller 528 can be further designed to be greater than the size of the conical piece 12 in the left-right direction, so as to ensure that the circumferential surface 529 of the roller 528 can completely contact the conical piece 12.

[0087] In addition, the roller 528 can be a structure with a hub and a rim. Its rim can be made of nylon or rubber with a certain hardness, so as to apply a certain force to the end of the spoke when contacting, and at the same time will not damage the conical piece 12 attached to the spoke body 10.

[0088] The description of the above-mentioned specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Modifications, equivalent replacements or other improvements to the embodiments of the present invention or some of its technical features that can be obtained by those of ordinary skill in the art through logical analysis, reasoning or limited experiments in combination with common general knowledge, ordinary technical knowledge in the field and / or the prior art shall be included within the protection scope of the present invention.
