[0044] The first tooth piece 2 and the third tooth piece 4 are fixed on the carbon fiber bracket 1 through the second rivet 6 .

[0045] In other embodiments of the present application, the number of teeth on the cassette flywheel can be more or less. For example, the cassette flywheel can also be provided with 2, 4, 5, etc. teeth. Optionally, the size of the teeth arranged on the cassette flywheel decreases from bottom to top.

[0046] Exemplarily, the thickness of the tooth plate is 1.6 mm, and the distance between adjacent tooth plates is 2.2 mm.

[0047] Furthermore, cassette flywheels are usually used in combination. Figure 1 In the method, a plurality of cassette flywheels are combined to obtain a cassette flywheel for a bicycle. The thickness of the combined cassette flywheel is 40.8±0.3 mm.

[0048] Optionally, the second tooth piece 3 is hollow, and the hollow part is circular. Further, the shape of the hollow part of the second tooth piece 3 matches the projection shape of the second step in the vertical direction, so that the second tooth piece 3 can be sleeved on the carbon fiber bracket 1.

[0049] Optionally, the third tooth piece 4 is hollow, and the hollow part is circular. Further, a protrusion is provided on the top of the carbon fiber bracket 1, and the protrusion is located above the second step. The shape of the hollow part of the third tooth piece 4 matches the projection shape of the protrusion in the vertical direction, so that the third tooth piece 4 can be sleeved on the carbon fiber bracket 1.

[0050] For example, please refer to Figure 3 , Figure 3 Disclosed is a schematic diagram of a carbon fiber bracket 1. A first through hole 11 and a second through hole 12 on the carbon fiber bracket 1 are located on a straight line with the same radius.

[0051] For example, please refer to Figure 4 , Figure 4 It shows a schematic diagram of a carbon fiber bracket 1. The first through hole 11 and the second through hole 12 on the carbon fiber bracket 1 are not located on a straight line with the same radius.

[0052] The present application embodiment discloses a process diagram of a method for manufacturing a carbon fiber bracket cassette flywheel. Figure 1 . Reference Figure 5 , the method comprising: Step S501: fix the first tooth piece in the bottom cavity of the manufacturing mold, and the shape of the bottom cavity matches the shape of the first tooth piece.

[0053] Optionally, the manufacturing mold is a combined mold, which includes a first single mold and a second single mold, and the manufacturing mold needs to be used by combining the two single molds. When manufacturing the cassette flywheel, the first single mold and the second single mold need to be combined first; after the manufacturing of the cassette flywheel is completed, the combination of the first single mold and the second single mold is cancelled, and the manufactured cassette flywheel is taken out.

[0054] Exemplarily, the shape of the bottom cavity is cylindrical, and the circular shape of the bottom cavity in the vertical direction is tangent to the first tooth plate.

[0055] Exemplarily, the first tooth piece is fixed in the bottom cavity of the manufacturing mold by a first robot.

[0056] Step S502: placing the carbon fiber bracket into the top cavity of the manufacturing mold, the shape of the top cavity matches the bottom shape of the carbon fiber bracket.

[0057] For example, please refer to Figure 3 and Figure 4 , the shape of the top cavity is the same as the projection shape of the carbon fiber bracket in the vertical direction.

[0058] For example, please refer to Figure 6 The top cavity is connected to the bottom cavity. After the first tooth piece is placed in the bottom cavity, when the carbon fiber bracket is placed in the top cavity, the first tooth piece can act as a bottom plate to limit the depth of the carbon fiber bracket entering the top cavity.

[0059] Exemplarily, the carbon fiber bracket is placed into the top cavity of the manufacturing mold by a second robot.

[0060] Step S503: adjusting the position of the first tooth piece in the bottom cavity so that the through hole on the first tooth piece is aligned with the first through hole and the second through hole on the carbon fiber bracket.

[0061] Exemplarily, a top surface image of a carbon fiber bracket is obtained; based on the top surface image, the occlusion conditions of the first through hole and the second through hole on the carbon fiber bracket are obtained, and the occlusion conditions are used to indicate the areas of the first through hole and the second through hole that are blocked by the first tooth plate; the first tooth plate in the bottom groove is rotated, and the occlusion conditions are read in real time; when the occlusion condition is unblocked, the rotation of the first tooth plate is stopped.

[0062] Step S504: Sleeve the second tooth piece onto the carbon fiber bracket so that the through hole on the second tooth piece is aligned with the first through hole on the carbon fiber bracket.

[0063] Exemplarily, according to the top surface image of the carbon fiber bracket, the second tooth piece is sleeved onto the carbon fiber bracket; the second tooth piece is rotated to align the through hole on the second tooth piece with the first through hole on the carbon fiber bracket.

[0064] Step S505: Use a first rivet to pass through the first through hole.

[0065] Optionally, the length of the first rivet is greater than the sum of the thickness of the first tooth plate, the thickness of the second tooth plate and the thickness of the first step.

[0066] Optionally, the difference between the radius of the first rivet and the radius of the first through hole is less than a preset radius error. For example, the preset radius may be 0.1 mm or 0.2 mm.

[0067] Exemplarily, the position of the first through hole is determined according to the top surface image, and then, according to the position of the first through hole, a first rivet is used to pass through the first through hole.

[0068] Step S506: Processing the first rivet so that the second tooth piece is fixed on the carbon fiber bracket through the first rivet.

[0069] Optionally, the first rivet is processed by mechanical riveting. After the first rivet is processed, the first rivet fixes the first tooth plate, the carbon fiber bracket and the second tooth plate.

[0070] Step S507: Sleeve the third tooth piece onto the carbon fiber bracket so that the through hole on the third tooth piece is aligned with the second through hole on the carbon fiber bracket.

[0071] Exemplarily, according to the top surface image of the carbon fiber bracket, the third tooth piece is sleeved onto the carbon fiber bracket; the third tooth piece is rotated to align the through hole on the third tooth piece with the second through hole on the carbon fiber bracket.

[0072] Step S508: Use a second rivet to pass through the second through hole.

[0073] Optionally, the length of the second rivet is greater than the sum of the thickness of the first tooth plate, the thickness of the third tooth plate and the thickness of the second step.

[0074] Exemplarily, the position of the second through hole is determined according to the top surface image, and then, according to the position of the second through hole, a second rivet is used to pass through the second through hole.

[0075] Step S509: Process the second rivet, so that the third tooth plate is fixed on the carbon fiber bracket through the second rivet to obtain the cassette flywheel.

[0076] Optionally, the second rivet is processed by mechanical riveting. After the second rivet is processed, the second rivet fixes the first tooth plate, the carbon fiber bracket and the third tooth plate.

[0077] In summary, when manufacturing the carbon fiber bracket cassette flywheel, the various components of the cassette flywheel are combined in sequence, the entire processing process is short, and the size of the processed cassette flywheel meets the design requirements. In addition, the overall weight of the manufactured cassette flywheel is reduced while maintaining a high strength.

[0078] In the following embodiment, after the second tooth piece is sleeved onto the carbon fiber bracket, the first through hole on the carbon fiber bracket needs to be aligned with the through hole on the second tooth piece for subsequent riveting operations. Figure 1 . Reference Figure 6 , the method comprising: Step S601: Acquire a top surface image of the carbon fiber bracket.

[0079] Optionally, a top surface image of the carbon fiber bracket is obtained by a camera, the camera is located above the carbon fiber bracket, and the camera photographs the carbon fiber bracket in a direction perpendicular to the carbon fiber bracket to obtain the top surface image.

[0080] In some other embodiments, the position of the carbon fiber bracket is determined by the top surface image, and the second tooth piece is sleeved onto the carbon fiber bracket according to the position of the carbon fiber bracket.

[0081] Step S602: identifying a first overlap degree between the first through hole and the through hole on the second tooth plate according to the top surface image, wherein the first overlap degree is used to represent an area of ​​the first through hole that is not blocked by the second tooth plate.

[0082] Exemplarily, whether the first through hole is blocked by the second tooth piece will display different colors, so the first overlap degree can be obtained according to the color distribution of the first through hole. For example, the color distribution of the first through hole is identified according to the top surface image; the area of ​​the first through hole blocked by the second tooth piece is calculated according to the color distribution to obtain the first overlap degree.

[0083] Exemplarily, the first overlap degree may also be obtained according to the exposed shape of the first through hole. For example, the exposed shape of the first through hole is identified according to the top surface image; the exposed shape is calculated to obtain the first overlap degree.

[0084] Step S603: When the first overlap degree is greater than a preset overlap degree, executing the step of using a first rivet to pass through the first through hole.

[0085] When the first overlap degree is greater than the preset overlap degree, it means that the first through hole has exposed the second tooth piece, and the first rivet can pass through the first through hole and expose the second tooth piece, so as to facilitate the subsequent processing of the first rivet, so that the first rivet can fix the first tooth piece, the carbon fiber bracket and the second tooth piece.

[0086] The preset overlap degree is a preset fixed value.

[0087] Step S604: when the first overlap degree is less than the preset overlap degree, rotating the second gear according to the first overlap degree.

[0088] When the first overlap degree is less than the preset overlap degree, it means that the first through hole exposes a small portion of the second tooth plate, and the first rivet cannot pass through the first through hole and expose the second tooth plate, which also makes it impossible to process the first rivet subsequently.

[0089] Exemplarily, when the second gear piece is rotated, the first overlap degree is monitored in real time, and when it is monitored that the second overlap degree is greater than a preset overlap degree, the rotation of the second gear piece is stopped.

[0090] In summary, when assembling the second tooth piece, the top surface image of the carbon fiber bracket will be acquired in advance, and the top surface image will be used to determine whether the first through hole is aligned with the through hole on the second tooth piece. If not aligned, the second tooth piece will be rotated to achieve alignment.

[0091] In the following embodiment, when the radius of the first through hole is too small, it is difficult to distinguish whether the first through hole is blocked by the second tooth plate from the top surface image captured by the camera. Therefore, in order to solve the above problem, the embodiment of the present application discloses a method for aligning through holes of a carbon fiber bracket cassette flywheel. Figure 2 . Reference Figure 7 , the method comprising: Step S701: When the radius of the first through hole is smaller than a preset radius, use a light source to illuminate the first through hole.

[0092] Exemplarily, a light source is used to vertically illuminate the first through hole, and the light source is on the same side as the top of the carbon fiber bracket.

[0093] The preset radius is a preset fixed value. For example, the preset radius is 1.5 mm.

[0094] Step S702: collecting the actual spot size on the imaging plane. The spot is formed on the imaging plane after the light emitted by the light source passes through the first through hole. The actual spot size includes the spot radius and the spot shape.

[0095] The imaging plane is on the same side as the bottom of the carbon fiber holder.

[0096] Optionally, the actual spot size on the imaging plane is collected using a camera, an optical sensor, a spot analyzer, or a light intensity meter.

[0097] Step S703: Calculate the ideal spot size according to the distance from the light source to the first through hole and the distance from the first through hole to the imaging plane.

[0098] In an actual production scenario, since the radius of the first through hole is much larger than the wavelength of the light source, the effect of the diffraction effect generated when the light passes through the first through hole on the light spot size can be ignored.

[0099] Exemplarily, assuming that the distance from the light source to the first through hole is L1, the distance from the first through hole to the imaging plane is L2, and the radius of the light source is a, the spot radius corresponding to the ideal spot size is r=a*L2 / L1.

[0100] Step S704: When the actual spot size matches the ideal spot size, a step of using a first rivet to pass through the first through hole is performed.

[0101] Optionally, the spot shapes of the actual spot size and the ideal spot size are compared. If the spot shapes of the two are different, it is considered that the actual spot size does not match the ideal spot size; if the spot shapes of the two are the same, the spot radius of the actual spot size and the ideal spot size are compared. When the difference between the spot radius of the two is less than the preset difference, it is considered that the actual spot size matches the ideal spot size; when the difference between the spot radius of the two is greater than the preset difference, it is considered that the actual spot size does not match the ideal spot size.

[0102] Step S705: when the actual spot size does not match the ideal spot size, rotating the second gear according to the first overlap degree.

[0103] Exemplarily, according to the first overlap degree, the overlap area and the shielding area of ​​the first through hole and the through hole on the second tooth piece are determined on the carbon fiber bracket. If the overlap area is located in the clockwise direction of the shielding area, the second tooth piece is rotated counterclockwise; if the overlap area is located in the counterclockwise direction of the shielding area, the second tooth piece is rotated clockwise.

[0104] During the process of rotating the second gear piece, the actual spot size is monitored in real time, and when it is detected that the actual spot size matches the ideal spot size, the rotation of the second gear piece is stopped.

[0105] In summary, when the radius of the first through hole is small, the actual spot size is used to determine whether the first through hole is aligned with the through hole on the second tooth plate, and the alignment can be determined even when the radius of the first through hole is small.

[0106] In the following embodiment, when using the light spot to detect whether the first through hole is aligned with the through hole on the second tooth plate, the shape of the light spot can be used to determine whether there is a burr inside the first through hole. If it is determined that there is a burr, this embodiment will use the first rivet to remove the burr inside the first through hole as much as possible. Therefore, the present application embodiment discloses a process diagram of a method for manufacturing a carbon fiber bracket cassette flywheel Figure 2 . Reference Figure 8 , the method comprising: Step S801: when it is detected that the spot shape corresponding to the actual spot size is a preset correction shape, a target first through hole corresponding to the actual spot size is obtained.

[0107] The spot shape corresponding to the actual spot size is ideally a circle, and the preset correction shape is a shape formed by removing the irregular shape with arc from the circle. Fig. 9 The preset correction shape 901.

[0108] The spot shape of the actual spot size corresponding to the target first through hole is the preset correction shape.

[0109] Step S802: using a first rivet to reciprocate in a target first through hole.

[0110] In this step, when the first rivet is used to reciprocate in the target first through hole, since the radius of the first rivet is close to the radius of the first through hole, the first rivet can fit the root of the burr during the process of entering the first through hole, so that the first rivet can produce a force to cut off the burr at the root of the burr, thereby achieving the effect of removing the burr. Furthermore, the reciprocating motion of the first rivet in the target first through hole is divided into two sections, one section is the hole entry motion, and the other end is the hole exit motion, wherein the hole entry motion is the first rivet from the suspended state to the state of fully entering the first through hole, and the hole exit motion is the first rivet from the state of fully entering the first through hole to the suspended state.

[0111] In some other embodiments, when the first rivet reciprocates in the target first through hole, the resistance value of the first rivet is monitored in real time. When it is detected that the first rivet stops moving and the resistance value is greater than the upper limit of the resistance, it means that the burr inside the first through hole is difficult to remove by the method of this embodiment, and it is necessary to stop the movement of the first rivet, remove the carbon fiber bracket from the manufacturing mold, and send a scrap signal to the terminal of the person in charge, which is used to indicate that the carbon fiber bracket enters the scrapping procedure.

[0112] In some other embodiments, when it is detected that the first rivet maintains a moving state and the monitored resistance value is greater than the upper limit of sliding friction, it indicates that the inner wall of the first through hole is too rough, which affects the riveting quality of the first rivet, so it is necessary to stop the movement of the first rivet and send an error signal to the responsible terminal, the error signal is used to indicate that the roughness of the inner wall of the first through hole on the carbon fiber bracket does not match the design requirements. The upper limit of sliding friction is less than the upper limit of resistance.

[0113] Step S803: Detect whether the actual spot size matches the ideal spot size.

[0114] If the actual spot size matches the ideal spot size, step S804 is executed; If the actual spot size does not match the ideal spot size, step S805 is executed.

[0115] Further, when the number of times the first rivet reciprocates in the first through hole reaches a preset number, step S803 is executed.

[0116] Step S804: If yes, the step of using the first rivet to pass through the first through hole is performed.

[0117] When the actual spot size matches the ideal spot size, it indicates that the burrs on the inner wall of the first through hole have been removed, and the step of using the first rivet to pass through the first through hole can be continued.

[0118] Step S805: If not, repeat the step of using the first rivet to reciprocate in the target first through hole.

[0119] When the actual spot size does not match the ideal spot size, it means that the burrs on the inner wall of the first through hole have not been removed, and step S802 may be continued to remove the burrs as much as possible.

[0120] Further, when the number of times of repeating the step of using the first rivet to reciprocate in the target first through hole reaches the number of times, the carbon fiber bracket is taken out of the manufacturing mold and a scrap signal is sent to the terminal of the person in charge.

[0121] In summary, the debris in the target first through hole can be removed by the reciprocating motion of the first rivet in the target first through hole, so that after the first rivet is fixed, the first rivet can play a better fixing role.

[0122] In the following embodiment, when the first rivet is used to pass through the first through hole, there may be a situation where the first through hole is not aligned with the through hole on the second tooth plate. At this time, the first rivet will lift up the second tooth plate located at the top of the carbon fiber bracket. Therefore, the present application embodiment discloses a process diagram of a method for manufacturing a carbon fiber bracket cassette flywheel. Figure 3 . Reference Fig.10 , the method comprising: Step S1001: in the process of using the first rivet to pass through the first through hole, the actual horizontality of the second tooth piece is obtained in real time.

[0123] Optionally, the actual level is obtained by a level meter. Further, the level meter is arranged above the carbon fiber support.

[0124] Step S1002: Determine whether the actual level is less than the preset level.

[0125] If the actual level is less than the preset level, step S1003 is executed; If the actual level is greater than the preset level, step S1004 and step S1005 are executed.

[0126] The preset level is a preset constant. The preset level can be adjusted according to actual needs.

[0127] Step S1003: If yes, continue to execute the step of using the first rivet to pass through the first through hole.

[0128] When the actual level is less than the preset level, it indicates that the first through hole and the through hole on the second tooth plate have been aligned, and the step of passing the first through hole through the first rivet can be continued.

[0129] Step S1004: If not, obtaining the raised portion of the second tooth piece according to the actual horizontality.

[0130] When the actual level is greater than the preset level, it means that the first through hole and the through hole on the second tooth plate are not aligned yet, and the two need to be aligned before the step of using the first rivet to pass through the first through hole is performed.

[0131] The raised portion of the second tooth piece refers to a position on the second tooth piece.

[0132] In some other embodiments, the resistance value of the first rivet is monitored in real time. When the change value of the resistance value is monitored to be greater than the preset change value, it is determined whether the actual levelness is less than the preset levelness.

[0133] Step S1005: controlling the second tooth plate to rotate toward the protruding portion, and simultaneously executing the step of using the first rivet to pass through the first through hole.

[0134] Exemplarily, an overlapping area between the first through hole and the through hole on the second tooth plate is determined on the carbon fiber bracket; the direction from the raised portion to the overlapping area is used as the rotation direction of the second tooth plate, and the rotation direction includes a clockwise direction and a counterclockwise direction; and the second tooth plate is controlled to rotate according to the rotation direction.

[0135] Exemplarily, in the process of controlling the second tooth piece to rotate toward the protruding portion and simultaneously executing the step of using the first rivet to pass through the first through hole, it is determined whether the actual level is less than the preset level. If the actual level is less than the preset level, it means that the first through hole and the through hole on the second tooth piece have been aligned, and it is necessary to stop executing this step. Furthermore, if it is not detected that the actual level is less than the preset level within the preset time, step S1005 is stopped, and a scrap signal is sent to the responsible terminal.

[0136] In summary, when the first rivet passes through the first through hole, if the through hole on the second tooth piece is not aligned with the first through hole, the second tooth piece will be rotated first to align the two, which is beneficial to the subsequent riveting process.

[0137] In the following embodiment, when there are other first rivets passing through the first through hole and the actual horizontality of the second tooth piece is not less than the preset horizontality, since part of the first through hole has been passed through by the first rivet, the second tooth piece can only rotate in a relatively limited space, and it is difficult to solve the problem of through hole misalignment by rotating the second tooth piece. Also, because when the second tooth piece is sleeved on the carbon fiber bracket, there is a certain reserve between the size of the second tooth piece and the carbon fiber bracket, allowing the first rivet to enter the first through hole at a smaller angle, and will not affect the subsequent riveting process. Therefore, the embodiment of the present application discloses a process diagram of a method for manufacturing a carbon fiber bracket cassette flywheel Figure 4 . Reference Fig.11 , the method comprising: Step S1101: When there are other first rivets passing through the first through hole and the actual level is not less than the preset level, control the second tooth plate to rotate toward the protruding portion.

[0138] Exemplarily, an overlapping area between the first through hole and the through hole on the second tooth plate is determined on the carbon fiber bracket; the direction from the raised portion to the overlapping area is used as the rotation direction of the second tooth plate, and the rotation direction includes a clockwise direction and a counterclockwise direction; and the second tooth plate is controlled to rotate according to the rotation direction.

[0139] Step S1102: Determine whether the first rivet passes through the first through hole.

[0140] When the first rivet does not pass through the first through hole, step S1103 is performed.

[0141] When the first rivet passes through the first through hole, it means that the through holes have been aligned, and there is no need to perform subsequent steps of this embodiment.

[0142] Step S1103: If not, setting the moving angle according to the position offset of the protruding portion relative to the center of the first through hole.

[0143] The movement angle is the angle from the vertical upward direction.

[0144] When the first rivet has not passed through the first through hole, since there are other first rivets passing through the first through hole, it will affect the rotation of the second tooth plate, making it difficult for the second tooth plate to rotate to a position where the first through hole is aligned with the through hole on the second tooth plate. Therefore, this step allows the first rivet to enter the first through hole at a certain angle relative to the vertical upward direction.

[0145] Exemplarily, the position offset between the position of the raised portion and the center of the first through hole is obtained, and the position offset is used to record the distance from the raised portion to the circular position of the first through hole; the ratio of the position offset to a preset length is calculated to obtain a sine value, wherein the preset length is the sum of the depth of the first through hole and the thickness of the first tooth plate; the sine value is calculated using an inverse sine function to obtain a movement angle.

[0146] Step S1104: when the moving angle is smaller than the preset angle, controlling the first rivet to pass through the first through hole along the moving angle.

[0147] The preset angle is a preset fixed value, and the specific value of the preset angle can be adjusted according to actual needs.

[0148] When the moving angle is greater than the preset angle, it means that the moving angle exceeds the allowable range of the carbon fiber bracket. If the first rivet needs to enter the first through hole according to the moving angle, it means that there is a dimensional defect in the carbon fiber bracket itself or the second tooth piece is not accurately fitted onto the carbon fiber bracket. In this case, a scrap signal needs to be sent to the responsible terminal.

[0149] In summary, when there are other first rivets passing through the first through hole and the actual horizontality is insufficient, the moving angle of the first rivet is changed so that the first rivet can pass through the first through hole.

[0150] In the following embodiment, when all the first rivets pass through the first through hole, in order to ensure that the subsequent riveting process can proceed smoothly, it is necessary to ensure that the first rivets are in a vertical state as much as possible. Fig.11 In the embodiment shown, there is a first rivet that enters the first through hole along the moving angle. Therefore, the present application embodiment discloses a process diagram of a method for manufacturing a carbon fiber bracket cassette flywheel. Figure 5 . Reference Fig.12 , the method comprising: Step S1201: After the first rivet passes through the first through hole, a physical image of the first rivet is acquired.

[0151] Optionally, a physical image of the carbon fiber bracket is obtained by a camera, the camera is located above the carbon fiber bracket, and the camera photographs the carbon fiber bracket in a direction perpendicular to the carbon fiber bracket to obtain the physical image.

[0152] Step S1202: Acquire a filling state of the first rivet in the first through hole according to the physical image.

[0153] The filling state is used to indicate whether the first rivet is tilted in the first through hole.

[0154] In some other embodiments, when the top surface of the first rivet is a plane, the filling state of the first rivet can be obtained by a distance sensor, and the camera is located above the carbon fiber bracket. For example, the distance value from the distance sensor to each point on the first rivet is obtained; if the variance of the aforementioned distance value is less than the preset variance, it means that the first rivet is not tilted in the first through hole; if the variance of the aforementioned distance value is greater than the preset variance, it means that the first rivet is tilted in the first through hole.

[0155] Step S1203: searching for a target first rivet having a target filling state in the first rivets according to the filling state, where the target filling state refers to the first rivet being in an inclined state in the first through hole.

[0156] The target first rivet is a first rivet that is tilted in the first through hole.

[0157] Step S1204: rotating the second gear according to the target filling state.

[0158] Exemplarily, the tilting direction of the first rivet is determined according to the target filling state; and the second tooth piece is rotated in the opposite direction of the tilting direction.

[0159] In summary, after the first rivet is assembled, the target first rivet in a tilted state is found, and the second tooth piece is rotated according to the target filling state of the target first rivet, so that the target first rivet can be placed flatly in the first through hole, which is beneficial to the subsequent riveting operation.
