Description

Technical Field

[0001] The invention relates to the technical field of spoke manufacturing, and in particular to a material cutting device. Background Art

[0002] In the prior application, the applicant proposed a solution for forming a tapered structure at the end of a carbon fiber spoke. Generally speaking, a tapered section is designed at the end of the spoke, and the outer diameter of the tapered section gradually increases along the length direction of the spoke toward the end of the spoke. The metal piece provided at the end of the spoke can form a limit fit with the tapered section in the length direction, thereby fixing the metal piece to the spoke body, solving the problem that the metal piece at the end of the carbon fiber spoke is difficult to combine and fix with the carbon fiber spoke body. After being assembled on the rim, the limit fit between the tapered section and the metal piece in the length direction can effectively ensure that the spoke has a good performance in withstanding the tension of the rim and the hub in the length direction. Figure 1 In the process of forming the tapered section, the applicant designed a flexible tapered sheet, which is unfolded on a plane into a right triangle, with two right-angled sides and a hypotenuse, wherein the right-angled side can be attached to the spoke end and the extension direction of the right-angled side is consistent with the extension direction of the spoke body, and then the tapered sheet attached to the spoke end is wound on the spoke end. Due to the triangular shape of the tapered sheet itself, a tapered section with an outer diameter gradually increasing toward the end of the spoke end is automatically formed at the spoke end. Before forming the tapered section, the metal piece on the spoke can be inserted into the spoke body first, and after the tapered section is formed, the metal piece can be inserted into the tapered section to form a limited fit between the two.

[0016] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0017] Technical solution one provides a material cutting device, which is used to cut the material into conical pieces for winding around the ends of spokes, and the conical pieces are objects with beveled edges cut from a rectangular cutting material. The material cutting device includes a frame, a rotating conveying assembly and a bevel cutting assembly; wherein the rotating conveying assembly is mounted on the frame and is provided with an intermittently rotating rotating mechanism, and a plurality of placement parts are arranged circumferentially on the rotating mechanism, and each time the rotating mechanism stops rotating, the positions of these placement parts correspond one by one to the preset loading station, bevel cutting station and unloading station; that is, before each rotation, the loading station, bevel cutting station and unloading station all have a placement part corresponding thereto, and then after a rotation, the positions of these placement parts will move to the next station, for example, when the loading station and the bevel cutting station are adjacent, the previous one will be moved to the next station. The placement part corresponding to the loading station when the rotation stops for the first time will correspond to the bevel cutting station when the rotation stops for the second time; with such arrangement, the placement parts can be cycled between the loading station, the bevel cutting station and the unloading station through the intermittent rotation of the rotating mechanism, the cut material can be laid flat on the placement part at the loading station, cut by the bevel cutting assembly at the bevel cutting station, and the conical piece obtained after cutting can be removed at the unloading station; wherein the bevel cutting assembly is arranged at the position corresponding to the bevel cutting station, and it can cut the cut material by the bevel cutting head moving back and forth along the first direction, thereby obtaining a conical piece with a bevel. Through the material cutting equipment, the production efficiency can be effectively improved and the labor cost can be reduced.

[0018] In particular, in the material cutting equipment, the rotating conveying component adopts intermittent rotation to transport materials. This material conveying method can realize automatic transportation and positioning of materials without manual intervention, thereby improving production efficiency; and, through intermittent rotation, multiple placement parts can be in different workstations at the same time, realizing parallel processing and further improving efficiency; at the same time, each workstation is arranged around the rotating mechanism, occupying a small area, and the material cutting equipment as a whole can be arranged more compactly.

[0019] More importantly, the rotating conveying assembly can form a better match with the bevel cutting assembly. Specifically, since the bevel cutting head in the bevel cutting assembly only moves in the first direction, and the first direction is obviously tilted, in order to accurately form a conical piece with a beveled edge through cutting, the cut material must be accurately cut. It is necessary to ensure that the position of the cut material placed on the placement portion accurately corresponds to the position of the bevel cutting assembly. The present technical solution adopts a rotating conveying assembly, in which the rotating mechanism has higher positioning accuracy than the conventional linear conveying method, thereby ensuring that the cut material can stay at the position corresponding to the bevel cutting head in the bevel cutting assembly every time, so that the bevel cutting assembly can accurately cut the cut material, ensuring the shape, size and position accuracy during bevel cutting.

[0020] In the second technical solution, a feeding and cutting assembly is provided, which is located at the feeding station and has a feeding cutter head, and the feeding cutter head can cut the original material along the second direction, thereby obtaining the cut material placed on the placement part. The feeding and cutting assembly can realize automatic cutting and feeding of the original material, further improving the degree of automation, while also ensuring accurate cutting of the original material, and obtaining the cut material suitable for subsequent bevel cutting.

[0021] In technical solution three, a feeding assembly is provided, which corresponds to the loading station and includes a feeding moving mechanism and a pressing mechanism, wherein the feeding moving mechanism has a receiving part for carrying the original material, the pressing mechanism can move with the receiving part and has a pressing part facing the receiving part, the pressing part can cooperate with the receiving part to press the original material, and then the feeding moving mechanism moves toward the placing part and places the original material on the placing part, and then the loading and cutting assembly cuts the original material. The feeding assembly can be used to automatically feed and position the original material, making the entire loading process fully automated; wherein, the feeding assembly 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; specifically, the relative position of the feeding assembly and the placement portion of the loading station is determined, which ensures that the position of the cut material on the placement portion along the first direction can be guaranteed to be accurate, and at the same time, the feeding moving mechanism in the feeding assembly moves a predetermined preset distance toward the placement portion 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, 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 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.

[0022] In technical solution four, the feeding component also includes a rolling mechanism, which adheres the original material 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 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 rolling shaft 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 and the pressing mechanism in the feeding component. Each mechanism works together during each loading to realize efficient and accurate loading of the original material.

[0023] In the fifth technical solution, a clamping assembly is provided, which includes a bevel clamping mechanism and a feeding clamping mechanism. Both clamping mechanisms can firmly clamp the cutting material on the placement part during the cutting process to prevent the material from moving or deforming due to the contact and movement of the cutter head during cutting, thereby ensuring the cutting accuracy and the accuracy of the bevel shape. At the same time, a bevel cutting groove is provided on the bevel clamping head of the bevel clamping mechanism, which provides a guide for the bevel cutter head, so that the bevel cutter head can cut along a predetermined track, further improving the accuracy and quality of bevel cutting.

[0024] In technical solution six, the bevel cutting assembly and the loading and cutting assembly use the same modular components, both of which include a cutting moving mechanism and a cutting mechanism. The cooperation of the cutting moving mechanism and the cutting mechanism can realize precise movement control of the cutter head in the up and down and horizontal directions. Each time cutting is performed, the cutter head can be moved down to the cutting material first, then moved horizontally to cut the cutting material, and then lifted up to avoid interfering with the normal operation of the rotating conveying assembly.

[0025] In technical solution seven, a waste discharge component and a vacuum negative pressure device are provided. The waste discharge component is located at the waste discharge station, and the waste discharge station is located between the bevel cutting station and the unloading station. At the waste discharge station, the waste materials other than the conical sheet can be taken away from the placement part after the cut materials are cut by the waste discharge component, so as to facilitate the efficient removal of the conical sheet at the unloading station. The waste discharge component includes a waste discharge adsorption head, which can form a negative pressure and move to the placement part to adsorb and fix the waste materials. After that, the waste discharge adsorption head moves along the fourth horizontal direction. When it reaches the preset discarding position, the waste discharge adsorption head can stop the negative pressure adsorption, so as to discard the waste materials to a specific position. Through the waste discharge component and the vacuum negative pressure device, the waste materials generated during the cutting process can be automatically removed from the placement part, thereby avoiding the accumulation of waste materials, keeping the working area clean, and improving the operation efficiency and stability of the equipment.

[0026] In technical solution eight, the rotating mechanism includes a rotating disk and a plurality of placement blocks uniformly arranged at a first angle along the circumference of the rotating disk, and a first negative pressure channel is provided in the placement block to fix the cut material on the placement portion by negative pressure adsorption through a first negative pressure port provided in the placement portion, wherein the rotating disk rotates around the first axis by a second angle each time, and the second angle is equal to the first angle. In this rotating mechanism, the material is fixed by vacuum adsorption, and the material can be uniformly adsorbed on the placement portion, avoiding deformation or displacement of the material that may be caused by mechanical clamping, and improving positioning accuracy and cutting stability. The placement blocks can be replaced independently, which is convenient for maintenance and replacement of placement blocks of different shapes or sizes to adapt to different materials and cutting requirements. Each time the rotating disk rotates by the second angle, the angle at which the placement blocks are arranged is the first angle, and the first angle and the second angle are equal, ensuring that after each rotation of the rotating disk, the placement blocks can accurately stay at each corresponding workstation.

[0027] In the ninth technical solution, an ejection mechanism is provided, which is installed on the frame and corresponds to the waste discharge station. The ejection rod in the ejection mechanism can reciprocate in the up and down direction. At the same time, an ejection channel is provided on the placement block corresponding to the waste position of the waste. The ejection rod can extend into the ejection channel to eject the waste from the placement block, thereby cooperating with the waste discharge adsorption head to take the waste away. Among them, since the cut material is adsorbed and fixed on the placement part by negative pressure adsorption, and at the same time in the bevel cutting station, the size of the waste after cutting is small. When the waste is adsorbed by the waste discharge adsorption head, due to the electrostatic adsorption of the placement part on the waste and the small size of the waste, it is easy for the waste discharge adsorption head to fail to absorb the waste. For this purpose, the ejection mechanism is specially provided, and the waste can be lifted from the placement part by the ejection mechanism to assist the waste discharge adsorption head to better adsorb and remove the waste. Especially for waste with strong adhesion, the ejection mechanism can effectively prevent waste residue. The dual functions of the ejection mechanism and the waste suction head improve the efficiency and reliability of waste discharge and ensure the cleanliness of the placement surface.

[0028] In the technical solution ten, a negative pressure connecting component is provided to realize the independent control and distribution of the vacuum negative pressure of multiple placement blocks. The first negative pressure port of each placement block is connected to the vacuum negative pressure device through independent second and third negative pressure channels, which ensures that the vacuum adsorption effect of each station is not affected by other stations, and improves the reliability and stability of vacuum adsorption. The cooperation between the negative pressure driving mechanism and the negative pressure connecting piece can accurately control the application and disconnection of negative pressure, so as to coordinate with the movement of the rotating disk. When the rotating disk rotates, the negative pressure connecting piece moves up to separate the second negative pressure port and the third negative pressure port. After the rotating disk rotates to the position and stops, the negative pressure connecting piece moves down to connect the third negative pressure port with the next second negative pressure port on the rotating disk. Through the negative pressure connecting component, in the equipment using the rotating disk, the problem of difficult arrangement of the negative pressure pipeline caused by the rotation of the rotating disk can be solved, which greatly simplifies the arrangement problem of the negative pressure pipeline.

[0056] Example

[0057] Reference Figure 2 An embodiment of the present invention relates to a material cutting device, which mainly includes a frame 20, a rotating conveying component 30, a bevel cutting component 40, a loading and cutting component 50, a feeding component 60, a clamping component 70, a waste discharge component 80, a vacuum negative pressure device and a negative pressure connecting component 90.

[0058] First refer to Figure 1 , which shows the structure of the spoke with the conical piece 12 attached. The spoke as a whole includes a spoke body 10, a connecting cap 11 and a conical piece 12, wherein there are two connecting caps 11, which are respectively sleeved on the spoke body 10 from both ends, and there are two conical pieces 12, 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 a glue station, and at the same time, one side surface of the conical piece 12 itself can be designed to be sticky, so that the side surface is used as the inner side during winding, so that the conical piece 12 will not fall apart after adhesion. The triangular shape of the conical piece 12 can automatically form a conical section at the end of the spoke after the conical piece 12 is adhered. The size and shape of the conical 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 outward to the position of the conical section, and the connecting cap 11 and the spoke body 10 are limited in the length direction through the conical section, which can effectively increase the tensile force that the connecting cap 11 can withstand when pulling the connecting cap 11. 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 wrapped around the spoke body 10, the conical piece 12 and the spoke body 10 can be cured into one through a curing process to prevent the conical piece 12 from falling off the spoke body 10. After the two are cured into one, the connecting cap 11 can be pulled to the position of the conical section.

[0059] Continue to refer to Figure 1The material cutting device involved in the embodiment of the present invention is used to cut the material into a conical piece 12 for winding the spoke end. The material in the present specification and claims includes two situations. 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 is a difference between the two in different processes. When the material cutting device is used for cutting, the final result is a conical piece 12 with a beveled edge. The shape of the conical piece 12 can be as follows: Figure 1 The triangle shape shown may also be a right-angled trapezoid with a hypotenuse. In this embodiment, the material is carbon fiber material.

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 mounted on the top of the main support, and the slide rail 22 extends in the left-right direction. The slider 23 is mounted on the slide rail 22, and the slider 23 can slide back and forth 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-right direction 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-right direction, so that the distance and respective positions of the two platforms 21 in the left-right direction can be adjusted. Among them, a driving motor or a driving cylinder can be set on the frame 20 corresponding to each platform 21, so as to control the movement of the platform 21 in an automated manner, and the position of the platform 21 can be accurately adjusted. In addition, referring to Figure 2 and Figure 4 The frame 20 also includes a flat plate-shaped driving mounting plate 24, 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 clamping assembly 70 and the negative pressure connecting assembly 90 are mounted on the driving mounting plate 24.

[0063] Reference Figure 3 , four stations are defined on the platform 21 of the frame 20, which are, in clockwise direction, a loading station 251, a bevel cutting station 252, a waste discharge station 253 and a unloading station 254. The central angle between each of these four stations is 90°, and they are all arranged around the first axis where the rotating mechanism 31 of the rotating conveying assembly 30 is located. The rotating mechanism 31 rotates intermittently, and each rotation is 90°, so that there is a placement portion 331 corresponding to a station each time the rotation stops. Among them, the loading station 251 is used to place the cut material on the placement portion 331, the bevel cutting station 252 is used to cut the cut material into a conical portion and waste, the waste discharge station 253 is used to take away the waste, and the unloading station 254 is used to take away the conical piece 12 or work in conjunction with other devices to complete other processes.

[0064] Among them, refer to Figure 4 , Figure 5 and Figure 8The rotating mechanism 31 includes a rotating disk 32 and a plurality of placement blocks 33; the placement blocks 33 are evenly arranged at a preset first angle along the circumferential interval of the rotating disk 32, and the top surface of the placement blocks 33 forms the placement portion 331; a first negative pressure channel connected to the vacuum negative pressure device is provided in the placement block 33, and a plurality of first negative pressure ports 332 connected to the first negative pressure channel are provided at a position corresponding to the placement portion 331 of the placement block 33, and the first negative pressure ports 332 form negative pressure through the vacuum negative pressure device to adsorb and fix the cut material; the rotating disk 32 is suitable for rotating around the first axis by a preset second angle each time, and the second angle is equal to the first angle.

[0065] Each time the rotating mechanism 31 stops rotating, the placement portion 331 rotates to a preset waste discharge station 253, and the waste discharge station 253 is located between the bevel cutting station 252 and the unloading station 254; the waste discharge assembly 80 is mounted on the frame 20 and located at the waste discharge station 253, and is provided with a waste discharge suction head 81 suitable for reciprocating along a fourth horizontal direction; the waste discharge suction head 81 is suitable for forming a negative pressure through the vacuum negative pressure device to bring the waste separated from the conical sheet 12 in the cut material on the placement portion 331 located at the waste discharge station 253 away from the placement portion 331. The waste discharge assembly 80 also includes an ejection mechanism 84, which is installed on the frame 20 and corresponds to the waste discharge station 253, and is provided with an ejection rod 841 suitable for reciprocating in the up and down directions; the placement block 33 is provided with an ejection channel 334 that passes through in the up and down directions at a position corresponding to the waste separated from the conical piece 12 in the cut material; the ejection rod 841 is suitable for extending into the ejection channel 334 and ejecting the waste from the placement block 33, so as to cooperate with the waste discharge suction head 81 to take the waste away.

[0066] Specifically, the vacuum negative pressure device can be arranged inside the frame 20 of the material cutting device. The vacuum negative pressure device can generate negative pressure after being powered on and transport the pressure to the required position through the negative pressure pipeline, thereby realizing 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.

[0067] Place block 33's structural reference Figure 8, which is roughly a rectangular block-shaped component, with a placement portion 331 formed on the upper surface of the placement portion 331, and the cut material can be placed on the placement portion 331, and when the cut material is placed on the placement portion 331, the sticky side of the cut material faces upward, and the non-sticky side faces downward. The placement block 33 is provided with a plurality of first negative pressure ports 332 at the position of the placement portion 331, and these first negative pressure ports 332 are arranged in a regular manner, and each first negative pressure port 332 is designed to be of a smaller size, and adjacent first negative pressure ports 332 are designed to have a smaller distance between them. Such a configuration allows the negative pressure formed by the first negative pressure ports 332 to act more evenly on the cut material when the cut material is placed on the placement portion 331, thereby preventing the cut material from being deformed or bent due to negative pressure adsorption. Among them, a first negative pressure channel is arranged inside the placement block 33, and the first negative pressure channel can be connected to the vacuum negative pressure device through a negative pressure pipeline, so that negative pressure is formed through the vacuum negative pressure device, and the cut material is adsorbed and fixed at the position of the first negative pressure port 332. Among them, it should be noted that the position of the first negative pressure port 332 should roughly correspond to the range of the conical piece 12 in the cut material, and the first negative pressure port 332 does not need to be arranged at the position of the waste material. The placement block 33 is provided with an ejection channel 334 that passes through from top to bottom at the position corresponding to the waste material, and the ejection rod 841 of the ejection mechanism 84 can move upward to eject the waste material located above the ejection channel 334 away from the placement block 33. In addition, referring to Figure 8 A beveled edge clearance groove 333 is also recessed on the top of the placement block 33. The position of the beveled edge clearance groove 333 corresponds to the position of the cut material to be cut, which can give way to the beveled edge cutter head 41, allowing the beveled edge cutter head 41 to pass through the cut material in the up and down directions, ensuring that the cut material is cut to form a conical piece 12.

[0068] The rotating disk 32 is a cross-shaped plate-shaped component having four ends spaced 90° apart from each other, and four placement blocks 33 are respectively fixedly mounted at one end position of the rotating disk 32. At the same time, the rotating conveying assembly 30 also includes a rotating driving mechanism 34, which includes a rotating motor 341 and a rotating connecting block 342. The rotating motor 341 is installed below the platform 21 of the frame 20, and the rotating connecting block 342 is arranged at the output end of the rotating motor 341. The rotating connecting block 342 can rotate around the first axis as the output end of the rotating motor 341 rotates. At the same time, the rotating connecting block 342 extends from the platform 21 from bottom to top and is fixedly connected to the rotating mechanism 31 by bolts. In this embodiment, the number of the placement blocks 33 in the rotating conveying assembly 30 is four, and the four placement blocks 33 are fixedly mounted on the outer edge of the rotating mechanism 31 along the circumferential direction, and the spacing angle between the placement blocks 33, that is, the first angle, is 90 degrees. Driven by the rotating drive mechanism 34, the angle of each rotation of the rotating mechanism 31, that is, the second angle, is also 90 degrees, and in the initial state, the four placement blocks 33 correspond to four workstations. After the rotating drive mechanism 34 rotates once, the corresponding placement block 33 originally corresponding to the previous workstation will rotate to the next adjacent workstation. In the rotating mechanism 31, the material is fixed by vacuum adsorption, and the material can be evenly adsorbed on the placement part 331, avoiding the deformation or displacement of the material that may be caused by mechanical clamping, and improving the positioning accuracy and cutting stability. The placement blocks 33 can be replaced independently, which is convenient for maintenance and replacement of placement blocks 33 of different shapes or sizes to adapt to different materials and cutting requirements. Each time the rotating disk 32 rotates the second angle, the angle at which the placement blocks 33 are arranged at intervals is the first angle, and the first angle and the second angle are equal, ensuring that after each rotation of the rotating disk 32, the placement blocks 33 can accurately stay at each corresponding workstation.

[0069] Furthermore, the negative pressure communication component 90 includes a negative pressure driving mechanism 91 and a negative pressure communication piece 92; the rotating disk 32 is provided with a plurality of second negative pressure channels corresponding to and connected with the first negative pressure channels of the placement blocks 33, and each of the second negative pressure channels is provided with a second negative pressure port 321 at one end away from the corresponding placement block 33; the negative pressure driving mechanism 91 is installed on the frame 20, and the negative pressure communication piece 92 is fixedly provided at the output end of the negative pressure driving mechanism 91, and is suitable for being driven by the negative pressure driving mechanism 91 to reciprocate in the first direction; the negative pressure communication piece 92 is provided with a negative pressure port 321 connected to the vacuum negative pressure channel 33; The vacuum negative pressure device provides independent pressure for each of the third negative pressure channels; a second negative pressure port 321 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 332 and the second negative pressure port 321 are arranged in the same number at a preset third angle at a circumferential interval relative to the first 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 32 so that the second negative pressure port 321 is connected to the first negative pressure port 332 at a corresponding position.

[0070] Specifically, refer to Figure 6 , Figure 7 and Figure 8The negative pressure drive mechanism 91 is fixedly mounted on the drive mounting plate 24. The main body of the negative pressure drive mechanism 91 is a cylinder, and its output end forms a negative pressure drive output end 911, which is fixedly connected to the negative pressure connecting piece 92. Four third negative pressure ports 921 are arranged around the first axis of the rotating mechanism 31 at intervals of 90 degrees, and each of the 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 321 are arranged at corresponding positions on the rotating disk 32. These four second negative pressure ports 321 are connected to the second negative pressure channel in the rotating disk 32, and each second negative pressure channel is connected to the first negative pressure channel of a placement block 33 through a negative pressure pipeline. In addition, two negative pressure drive sliding rods 912 extending in the up-down direction are also provided on both sides of the main body of the negative pressure drive mechanism 91, which can ensure that the negative pressure drive output end 911 drives the negative pressure connecting piece 92 to move in the up-down direction. When the rotating mechanism 31 is in a state of stopping rotation, the negative pressure connecting member 92 can be driven by the negative pressure driving mechanism 91 to move downward, and each third negative pressure port 921 can be docked and connected with a second negative pressure port 321 at a corresponding position. Before the rotating disk 32 rotates, the negative pressure connecting member 92 is driven by the negative pressure driving mechanism 91 to move upward, and the third negative pressure port 921 leaves the corresponding second negative pressure port 321. When the rotating disk 32 rotates 90 degrees to the next position, the negative pressure connecting member 92 can be driven by the negative pressure driving mechanism 91 to move downward and make the third negative pressure port 921 docked and connected with a second negative pressure port 321 at a corresponding position. In order to ensure the sealing effect of docking and 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 to the third negative pressure port 921 to dock with the second negative pressure port 321, the sealing ring will be squeezed by the upper surface of the rotating disk 32, thereby sealing the gap between the third negative pressure port 921 and the second negative pressure port 321. Through the negative pressure communication component 90, the vacuum negative pressure of multiple placement blocks 33 is independently controlled and distributed. The first negative pressure port 332 of each placement block 33 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 91 and the negative pressure communication member 92 can accurately control the application and disconnection of negative pressure, so as to coordinate with the movement of the rotating disk 32. When the rotating disk 32 rotates, the negative pressure communication member 92 moves up to separate the second negative pressure port 321 and the third negative pressure port 921. After the rotating disk 32 rotates to the position and stops, the negative pressure communication member 92 moves down to connect the third negative pressure port 921 with the next second negative pressure port 321 on the rotating disk 32. Through the negative pressure communication component 90, in the equipment using the rotating disk 32, the problem of difficult arrangement of the negative pressure pipeline caused by the rotation of the rotating disk 32 can be solved, which greatly simplifies the arrangement problem of the negative pressure pipeline.

[0071] The waste discharge assembly 80 is provided with a waste discharge drive mechanism 83. The waste discharge drive mechanism 83 adopts a cylinder device in this embodiment, which is fixedly mounted on the support rod of the drive mounting plate 24 to form a fixed connection with the frame 20. At the same time, the output end of the waste discharge drive mechanism 83 forms a waste discharge drive output end 82, and a waste discharge adsorption head 81 is fixedly mounted on the waste discharge drive output end 82. The waste discharge adsorption head 81 is connected to the vacuum negative pressure device and can adsorb the waste on the placement part 331 by negative pressure adsorption. Among them, the waste discharge drive output end 82 is set to reciprocate in the left and right directions, so as to drive the waste discharge adsorption head 81 to reciprocate in the left and right directions, and the position of the waste discharge adsorption head 81 in the up and down direction is slightly higher than that of the placement part 331, so as to avoid interference between the waste discharge adsorption head 81 and the placement block 33. In the ejection mechanism 84 in the waste discharge assembly 80, the ejection drive cylinder 842 is fixedly mounted on the platform 21, and an ejection rod 841 is fixedly arranged at the output end of the ejection drive cylinder 842, and the ejection drive cylinder 842 can drive the ejection rod 841 to move up or down. When the placement block 33 moves to the top of the ejection mechanism 84, the ejection rod 841 can move upward and extend into the ejection channel 334 of the placement block 33, and the waste is ejected from the placement block 33. At the same time, the waste discharge adsorption head 81 moves to the top of the waste, and the waste is adsorbed onto the waste discharge adsorption head 81 by negative pressure. Then, the ejection rod 841 moves downward to leave the ejection channel 334, and at the same time, the waste discharge adsorption head 81 moves away from the placement block 33 to reach the waste position. At the waste position, the waste discharge adsorption head 81 disconnects the negative pressure, and the waste falls from the waste discharge adsorption head 81 to the waste position. The platform 21 may be provided with an opening at the waste position, and a waste receiving bucket may be provided below the opening to receive waste.

[0072] A waste discharge assembly 80 and a vacuum negative pressure device are provided. The waste discharge assembly 80 is located at the waste discharge station 253. The waste discharge station 253 is located between the bevel cutting station 252 and the unloading station 254. At the waste discharge station 253, the waste materials other than the conical sheet 12 can be taken away from the placement portion 331 by the waste discharge assembly 80 after the cut materials are cut, so as to facilitate the efficient removal of the conical sheet 12 at the unloading station 254. The waste discharge assembly 80 includes a waste discharge adsorption head 81. The waste discharge adsorption head 81 can form a negative pressure and move to the placement portion 331 to adsorb and fix the waste materials. After that, the waste discharge adsorption head 81 moves along the fourth horizontal direction. When it reaches the preset discarding position, the waste discharge adsorption head 81 can stop the negative pressure adsorption, so as to discard the waste materials to a specific position. Through the waste discharge assembly 80 and the vacuum negative pressure device, the waste materials generated during the cutting process can be automatically removed from the placement portion 331, thereby avoiding the accumulation of waste materials, keeping the working area clean, and improving the operation efficiency and stability of the equipment. In addition, since the cut material is adsorbed and fixed on the placement portion 331 by negative pressure adsorption, and the size of the waste after cutting is relatively small in the bevel cutting station 252, when the waste is adsorbed by the waste discharge adsorption head 81, due to the electrostatic adsorption of the waste by the placement portion 331 and the influence of the smaller size of the waste, it is easy for the waste discharge adsorption head 81 to fail to adsorb the waste. For this purpose, the ejection mechanism 84 is specially provided, and the waste can be lifted from the placement portion 331 by the ejection mechanism 84, which assists the waste discharge adsorption head 81 to better adsorb and remove the waste, especially for waste with strong adhesion, the ejection mechanism 84 can effectively prevent the waste from remaining. The dual role of the ejection mechanism 84 and the waste discharge adsorption head 81 improves the efficiency and reliability of waste discharge and ensures the cleanliness of the surface of the placement portion 331.

[0073] Reference Figure 4 and Figure 5 In the material cutting device, the feeding and cutting assembly 50 is installed on the frame 20 and located at the feeding station 251, and is provided with a feeding cutter head 51 suitable for reciprocating along the horizontal second direction; the feeding cutter head 51 is suitable for cutting the original material along the second direction to obtain the cut material placed on the placement portion 331 located at the feeding station 251. Wherein, the bevel cutting assembly 40 and the feeding and cutting assembly 50 both include a cutting moving mechanism 42 and a cutting mechanism 43; the output end of the cutting moving mechanism 42 is suitable for reciprocating along the up and down direction; the cutting mechanism 43 is installed at the output end of the cutting moving mechanism 42, and its output end is suitable for reciprocating along the first direction or the second direction; the bevel cutter head 41 and the feeding cutter head 51 are installed at the corresponding output ends of the cutting mechanism 43.

[0074] The bevel cutting assembly 40 is arranged at the bevel cutting station 252 of the frame 20, and is provided with a bevel cutter head 41, which can reciprocate in the first direction, so as to cut the cutting material into a conical piece 12 with a bevel. The first direction is inclined to the front-back direction, so that the bevel cutter head 41 can cut the cutting material at an angle. The feeding and cutting assembly 50 is arranged at the feeding station 251 of the frame 20, and is provided with a feeding cutter head 51, which can reciprocate in the left-right direction, so as to cut the original material into the cutting material, and before the feeding cutter head 51 cuts, part of the original material has been placed on the placement portion 331, and after the feeding cutter head 51 cuts, the part originally placed on the placement portion 331 forms the cutting material, and the rest of the original material can continue to be used in the next feeding and cutting. A feeding and cutting assembly 50 is provided, which is located at the feeding station 251 and has a feeding cutter head 51, and the feeding cutter head 51 can cut the original material along the second direction, so as to obtain the cut material placed on the placement portion 331. The feeding and cutting assembly 50 can realize automatic cutting and feeding of the original material, further improving the degree of automation, and also ensuring accurate cutting of the original material, so as to obtain the cut material suitable for subsequent bevel cutting.

[0075] Specifically, the bevel cutting assembly 40 and the feeding cutting assembly 50 have the same structure. The cutting moving mechanism 42 includes a cutting bracket 44, which is fixedly mounted on the platform 21, and a cutting drive cylinder 421 of the cutting moving mechanism 42 is mounted on the cutting bracket 44, and the output end of the cutting drive cylinder 421 can reciprocate in the up and down directions; the cutting mechanism 43 is mounted on the output end of the cutting drive cylinder 421, and the cutting mechanism 43 includes a cutter head drive cylinder 431, and the output end of the cutter head drive cylinder 431 can reciprocate in the left and right directions. At the same time, a cutter head is mounted on the output end of the cutter head drive cylinder 431, and the cutter head is respectively a bevel cutter head 41 and a feeding cutter head 51 according to the application of the bevel cutting assembly 40 or the feeding cutting assembly 50. When cutting, the cutting moving mechanism 42 first lifts the cutting mechanism 43 to move the cutter head away from the rotating mechanism 31, and the cutting mechanism 43 drives the cutter head to the initial position of cutting. When the rotating mechanism 31 rotates to make the placement part 331 reach below the cutter head, the cutting moving mechanism 42 drives the cutting mechanism 43 to move downward, so that the cutter head contacts the cut material on the placement part 331, and then the cutting mechanism 43 drives the cutter head to move horizontally, and the cutter head in the bevel cutting assembly 40 will also enter the bevel giving way groove 333, thereby cutting the original material or the cut material. The power source of the cutting moving mechanism 42 and the cutting mechanism 43 can both come from the vacuum negative pressure device. The bevel cutting assembly 40 and the loading and cutting assembly 50 use the same modular components, both of which include a cutting movement mechanism 42 and a cutting mechanism 43. The cooperation of the cutting movement mechanism 42 and the cutting mechanism 43 can realize precise movement control of the cutter head in the up and down directions and the horizontal directions. Each time cutting is performed, the cutter head can be moved down to the cutting material first, then moved horizontally to cut the cutting material, and then lifted up to avoid interfering with the normal operation of the rotating conveying assembly 30.

[0076] In addition, refer to Figure 6 and Figure 7The clamping assembly 70 includes a bevel clamping mechanism 71 and a material clamping mechanism 72; the bevel clamping mechanism 71 is installed on the frame 20 and corresponds to the bevel cutting station 252, and is provided with a bevel clamping head 711 suitable for reciprocating along the up and down directions; the bevel clamping head 711 is suitable for clamping or loosening the corresponding cutting material on the placement portion 331, and is provided with a bevel cutting groove 712 extending along the first direction and penetrating up and down, and the position of the bevel cutting groove 712 Corresponding to the position where the bevel needs to be formed on the cut material located on the corresponding placement portion 331; the bevel cutter head 41 is suitable for extending into the bevel cutting groove 712 and moving along the bevel cutting groove 712; the feeding and clamping mechanism 72 is installed on the frame 20 and corresponds to the feeding station 251, which is provided with a feeding and clamping head 721 suitable for reciprocating movement in the up and down directions; the feeding and clamping head 721 is suitable for clamping or loosening the cut material on the corresponding placement portion 331.

[0077] Specifically, the bevel pressing head 711 and the feeding pressing head 721 are both block-shaped components, which can move up and down driven by the bevel pressing mechanism 71 and the feeding pressing mechanism 72, and press the cut material located at the placement portion 331 when moving down. Among them, the bevel pressing mechanism 71 and the feeding pressing mechanism 72 are both installed on the drive mounting plate 24 of the frame 20, and both include a pressing drive cylinder 73, a pressing sliding rod 74 and a pressing adapter plate 75. The difference between the two is that the bevel pressing mechanism 71 corresponds to the placement portion 331 of the bevel cutting station 252, and the feeding pressing mechanism 72 corresponds to the placement portion 331 of the feeding station 251. The clamping drive cylinder 73 is fixedly mounted on the drive mounting plate 24. The output end of the clamping drive mechanism is located below the drive mounting plate 24 and can reciprocate in the up and down directions. A clamping adapter plate 75 is fixed to the output end by bolts. The bevel clamping head 711 and the feeding clamping head 721 are both fixed to the corresponding clamping adapter plate 75 by bolts. In addition, two clamping sliding rods 74 are also provided in the clamping drive mechanism. The two clamping sliding rods 74 are slidably connected to the drive mounting plate 24 in the up and down directions, that is, under the restriction of the drive mounting plate 24, the two clamping sliding rods 74 can only move in the up and down directions. The two clamping sliding rods 74 are fixedly connected to the clamping adapter plate 75, thereby limiting the bevel clamping head 711 and the feeding clamping head 721 to move only in the up and down directions, thereby ensuring the accuracy of the movement routes of the bevel clamping head 711 and the feeding clamping head 721. In addition, referring to Figure 6 and Figure 7The bevel pressing head 711 is also provided with a bevel cutting groove 712 corresponding to the bevel giving way groove 333 on the corresponding placement block 33. The bevel cutting groove 712 passes through the bevel pressing head 711 in the up-down direction, and is open at the end facing the bevel cutting assembly 40. The bevel cutter head 41 in the bevel cutting assembly 40 will extend into the bevel cutting groove 712 to ensure the accurate cutting position of the cut material. A clamping assembly 70 is provided, and the clamping assembly 70 includes a bevel clamping mechanism 71 and a feeding clamping mechanism 72. Both clamping mechanisms can firmly clamp the cut material on the placement portion 331 during the cutting process to prevent the material from moving or deforming due to the contact and movement of the cutter head with the material during cutting, thereby ensuring the cutting accuracy and the accuracy of the bevel shape. At the same time, a bevel cutting groove 712 is provided on the bevel pressing head 711 of the bevel pressing mechanism 71, and the bevel cutting groove 712 provides a guide for the bevel cutter head 41, so that the bevel cutter head 41 can cut along a predetermined trajectory, further improving the accuracy and quality of bevel cutting.

[0080] Specifically, refer to Fig.10 , the feeding assembly 60 can conveniently and accurately convey the raw material to the placement portion 331 of the loading station 251. Among them, when the feeding assembly 60 is used, the raw material and the release film are bonded to form a composite film roll, and the shape of the composite film roll can conveniently store the raw material and prevent the raw material from being dirty. The rolling mechanism 63 of the feeding assembly 60 includes a rolling bracket 633, which is fixedly mounted on the platform 21 of the frame 20. At the same time, the rolling bracket 633 is equipped with a loading rolling shaft 631, a rolling drive motor 634, a first guide shaft 635 and a second guide shaft 636. The axis directions of the above shafts are all left and right directions, that is, consistent with the cutting direction of the loading and cutting assembly 50. The recycling rolling shaft 632 is arranged at the output end of the rolling drive motor 634. Through the rolling drive motor 634, the recycling rolling shaft 632 can automatically rotate, and its rotation axis is also along the left and right direction. The first guide shaft 635 and the second guide shaft 636 are arranged in front of the loading roller shaft 631, and the first guide shaft 635 and the second guide shaft 636 are arranged symmetrically in the up and down directions, wherein the side wall of the first guide shaft 635 forms a groove structure, and the width of the composite film roll is consistent with the inner wall width of the groove structure. At the same time, the second guide shaft 636 is located above the first guide shaft 635, and it can extend into the groove structure formed by the side wall of the first guide shaft 635, thereby pressing the composite film roll against the side wall of the first guide shaft 635, thereby guiding the composite film roll to be transported forward.

The upper surface of the material receiving block 613 is provided with a material receiving portion 611. The material receiving portion 611 is a recessed groove extending in the front-to-back direction. The front and rear ends of the groove are open, and the width of the groove in the left-right direction is consistent with the width of the original material. A return shaft 614 is also provided at the front end of the material receiving block 613. The return shaft 614 is used to pull the release film peeled off from the original material back to the recovery rolling shaft 632. The pressing mechanism 62 includes a pressing driving cylinder 622 fixedly mounted on the material receiving block 613. The output end of the pressing driving cylinder 622 can reciprocate in the up and down directions and is fixed with a pressing block 623. The pressing block 623 is provided with a pressing portion 621 facing the material receiving portion 611. The pressing portion 621 can extend into the material receiving portion 611 and its width in the left and right directions is adapted to the width of the material receiving portion 611. When feeding, the composite film roll is placed on the feeding roller shaft 631, and the composite film roll passes through the first guide shaft 635 and the second guide shaft 636, and then is guided to the position of the feeding moving mechanism 61 and the pressing mechanism 62. At this time, the original material and the release film in the composite film roll are peeled off, and the release film is located at the top and guided to the return shaft 614 and then wound onto the recovery roller shaft 632. The original material is placed in the receiving part 611 and passes through the gap between the receiving part 611 and the pressing part 621, and the original material is extended from the front end of the receiving part 611. Afterwards, the pressing part 621 presses the original material, and the feeding movable mechanism 61 drives the receiving block 613 to move forward a preset distance, which is the front-to-back dimension of the cutting material to be cut at the loading station 251. At this time, the end of the original material will be placed on the placement part 331, and then the loading and cutting component 50 will run to cut off the end of the original material, and the part on the placement part 331 can form the cutting material. Then, the pressing part 621 is lifted up, and the feeding movable mechanism 61 is retracted. At this time, since the recovery roller 632 pulls the composite film roll, the original material will not be retracted with the feeding movable mechanism 61.

[0082] 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 331; specifically, the relative position of the feeding assembly 60 and the placement portion 331 of the loading station 251 is determined, which ensures that the position of the cut material on the placement portion 331 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 331 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 331, and then the original material is cut by the loading and cutting assembly 50, so that the accuracy of the size and position of the cut material on the placement portion 331 can be guaranteed, thereby improving the accuracy of the cutting position of the cut material by the bevel cutting assembly 40 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.

[0083] The material cutting device according to the embodiment of the present invention is used to cut the material into conical pieces 12 for winding around spoke ends. The conical pieces 12 are objects with oblique edges cut from a rectangular cutting material. The material cutting equipment includes a frame 20, a rotating conveying assembly 30 and a bevel cutting assembly 40; wherein the rotating conveying assembly 30 is mounted on the frame 20 and is provided with an intermittently rotating rotating mechanism 31, and a plurality of placement portions 331 are arranged circumferentially on the rotating mechanism 31, and each time the rotating mechanism 31 stops rotating, the positions of the placement portions 331 correspond to the preset loading station 251, the bevel cutting station 252 and the unloading station 254 one by one; that is, before each rotation, the loading station 251, the bevel cutting station 252 and the unloading station 254 all have a placement portion 331 corresponding thereto, and then after a rotation, the positions of the placement portions 331 will move to the next station, for example, when the loading station 251 and the bevel cutting station 252 are adjacent to each other. , the placement part 331 corresponding to the loading station 251 when the rotation stopped last time will correspond to the bevel cutting station 252 when the rotation stopped this time; with such arrangement, the placement parts 331 can be circulated between the loading station 251, the bevel cutting station 252 and the unloading station 254 through the intermittent rotation of the rotating mechanism 31, and the cut material can be laid flat on the placement part 331 at the loading station 251, and can be cut by the bevel cutting assembly 40 at the bevel cutting station 252, and the conical piece 12 obtained after cutting can be removed at the unloading station 254; wherein, the bevel cutting assembly 40 is arranged at a position corresponding to the bevel cutting station 252, and can cut the cut material by the bevel cutting head moving back and forth along the first direction, thereby obtaining a conical piece 12 with a bevel. Through the material cutting equipment, the production efficiency can be effectively improved and the labor cost can be reduced. In particular, in the material cutting equipment, the rotating conveying assembly 30 uses an intermittent rotation method to convey materials. This material conveying method can realize automatic conveying and positioning of materials without manual intervention, thereby improving production efficiency; and through intermittent rotation, multiple placement parts 331 can be in different workstations at the same time, realizing parallel processing and further improving efficiency; at the same time, each workstation is arranged around the rotating mechanism 31, which occupies a small area, and the material cutting equipment as a whole can be arranged more compactly. More importantly, the rotating conveying assembly 30 can form a better match with the bevel cutting assembly 40. Specifically, since the bevel cutting head in the bevel cutting assembly 40 only moves in the first direction, and the first direction is obviously inclined, the cut material must be accurately cut to form a conical piece 12 with a bevel, and it is necessary to ensure that the position of the cut material placed on the placement part 331 accurately corresponds to the position of the bevel cutting assembly 40.The present technical solution adopts a rotating conveying assembly 30, wherein the rotating mechanism 31 has higher positioning accuracy than the conventional linear conveying method, thereby ensuring that the cut material can stay at the position corresponding to the bevel cutting head in the bevel cutting assembly 40 each time, so that the bevel cutting assembly 40 can accurately cut the cut material and ensure the shape, size and position accuracy during bevel cutting.
