Description

Hairpin manufacturing device and hairpin manufacturing system

[0001] The present invention relates to a hairpin manufacturing device and a hairpin manufacturing system for bending and aligning hairpins.

[0002] The technology that forms the background of the present invention relates to a technology for manufacturing hairpins for motors.

[0003] The conventional process for manufacturing hairpins, as illustrated in Figure 1, involved workers manually transferring and aligning hairpins bent in a bending machine to an alignment machine. In other words, the bending and alignment processes were performed on separate pieces of equipment, requiring manual movement by workers.

[0004] This conventional hairpin manufacturing process relied on manual transport by workers, necessitating the need for storage racks or other storage space for the bent materials. This resulted in spatial constraints on the manufacturing facility, and the need for storage and management of both the equipment and the materials.

[0005] Additionally, there was a risk that the materials would be deformed or foreign substances would be introduced because workers directly fed the materials into the sorter, which would not only lead to a decline in quality but also to damage to the sorter.

[0006] In addition, as the bent material is transported to the alignment machine, the shape of the material is visually inspected by the worker. However, there is a concern that the completion and quality of the hairpin may deteriorate as materials with poor shapes are fed into the alignment machine.

[0007] Meanwhile, in conventional manufacturing processes, when the target model is changed during production, as illustrated in Figure 2, the remaining stripped / cut materials become unusable and must be discarded. This not only reduces productivity, but also necessitates the manipulation of materials and equipment when changing models, resulting in inconvenient work for workers.

[0008] The present invention aims to improve the limitations of the prior art as described above.

[0009] Accordingly, the present specification seeks to provide an embodiment in which a bending process and an alignment process can be performed.

[0010] In addition, we aim to provide an embodiment that can prevent the disposal of residual materials removed when changing models during the production process.

[0011] In addition, it is intended to provide an embodiment in which post-forming inspection and correction of a hairpin can be performed automatically.

[0012] In addition, an embodiment is provided in which a material can be stably transferred to an alignment machine after a bending process.

[0013] The present invention, which aims to solve the above-described problem, uses a problem-solving means to perform each process by having the material pass from one side to the other side and return to the one side.

[0014] Specifically, the process is characterized in that a supply section for supplying materials, a primary transport section for transporting materials for the first time, a bending section for bending materials, a secondary transport section for transporting materials for the second time, and an alignment section for aligning materials are arranged in a D shape, so that materials are supplied from one side, bent from the other side, and then aligned from the one side.

[0015] In addition, it is characterized in that the peeling part and cutting part change positions in a certain order from a certain point in time before the model change, thereby responding to the model change.

[0016] In addition, it is characterized by performing vision inspection on the material after bending and controlling the settings of the bending mold based on the inspection results.

[0017] In addition, it is characterized by transporting hairpins one by one to the alignment section using a dedicated feeder equipped with a hairpin holder.

[0018] The features described above may be applied to a device for bending a hairpin, a device for aligning a hairpin, a device for manufacturing a hairpin, a device for manufacturing a hairpin, equipment and facilities for manufacturing a hairpin, a system for manufacturing a hairpin, and a system for manufacturing a hairpin, or may be implemented as a device for aligning a hairpin, a device for manufacturing a hairpin, a device for manufacturing a hairpin, equipment and facilities for manufacturing a hairpin, a system for manufacturing a hairpin, and a system for manufacturing a hairpin, and the present specification provides an embodiment of a hairpin manufacturing device and a hairpin manufacturing system that use the features described above as a means for solving a problem.

[0067] A hairpin manufacturing device according to an embodiment (hereinafter referred to as a manufacturing device) means a device, facility, or equipment for manufacturing (or producing) a hairpin.

[0068] The above manufacturing device may be a device for manufacturing the hairpin, including a plurality of devices.

[0069] Here, the plurality of devices may be devices that perform a manufacturing process of a hairpin.

[0070] The above plurality of devices may include, for example, a device for bending and aligning the material of the hairpin.

[0071] Accordingly, the above manufacturing device may be a device that performs a bending process and an alignment process of a material.

[0072] The above-described plurality of devices may further include a device for supplying materials and a device for transporting materials.

[0073] Additionally, each of the plurality of devices may include a plurality of devices.

[0074] The above manufacturing device may be a device in which the above multiple devices are integrated into one piece of equipment.

[0075] The configuration of the above manufacturing device (100) may be as shown in FIGS. 3 and 4.

[0076] FIG. 3 and FIG. 4 are diagrams of the manufacturing device (100) viewed from above. The manufacturing device (100) may be implemented in a form in which the left and right sides or the top and bottom are reversed in the arrangement as shown in FIG. 3 and FIG. 4.

[0077] The above manufacturing device (100) includes a supply unit (110), a first transfer unit (120), a first bending unit (130), a second bending unit (140), a second transfer unit (150), and an alignment unit (160), as shown in FIGS. 3 and 4.

[0078] In the manufacturing device (100), the supply unit (110) is arranged on one side (Z1) of the manufacturing device (100) to supply the material of the hairpin, the first transfer unit (120) transfers the material supplied from the supply unit (110) toward the other side (Z2), the first bending unit (130) is arranged on the other side (Z2) to perform a first bending of the material transferred from the first transfer unit (120), the second bending unit (140) is arranged on the other side (Z2) to perform a second bending of the material supplied from the first bending unit (130), the second transfer unit (150) transfers the material bent by the second bending unit (140) toward the one side (Z1), and the alignment unit (160) is arranged on the one side (Z1) to perform a second bending of the material supplied from the second transfer unit (150). By aligning the transported material, a bending and alignment process may be performed to manufacture the material into the hairpin.

[0079] In this way, the manufacturing device (100) can move the material in the following order: the supply unit (110), the first transfer unit (120), the first bending unit (130), the second bending unit (140), the second transfer unit (150), and the alignment unit (160).

[0080] That is, the material moves from the one side (Z1) to the other side (Z2) in the manufacturing device (100), and then moves to the one side (Z1), so that the material moves in the shape of the letter D, and the bending and alignment processes can be performed in one piece of equipment.

[0081] Here, the one side (Z1) may correspond to the left side of the manufacturing device (100) when the manufacturing device (100) is viewed from above, and in this case, the other side (Z2) may correspond to the right side of the manufacturing device (100).

[0082] Alternatively, conversely, the one side (Z1) may correspond to the right side of the manufacturing device (100), and the other side (Z2) may correspond to the left side of the manufacturing device (100).

[0083] The above manufacturing device (100) can be driven and controlled by a control unit (200) that controls the manufacturing device (100).

[0084] The above control unit (200) may be a control device that controls the manufacturing device (100) so that a process for manufacturing the hairpin is performed.

[0085] The above control unit (200) can control the operation of each of the supply unit (110), the first transfer unit (120), the first bending unit (130), the second bending unit (140), the second transfer unit (150), and the alignment unit (160).

[0086] A specific example of the manufacturing device (100) including the supply unit (110), the first transfer unit (120), the first bending unit (130), the second bending unit (140), the second transfer unit (150), and the alignment unit (160) may be as shown in FIG. 5.

[0087] The above supply unit (110) can be placed at one end (Z1-1) of the one side (Z1).

[0088] The above supply unit (110) can supply the material to the first transport unit (120).

[0089] Here, the material may be a coil.

[0090] The above supply unit (110) can supply the material to the first transfer unit (120) by rotating the bobbin on which the material is wound in the opposite direction to the winding direction.

[0091] An example of the above supply unit (110) may be as shown in FIG. 6.

[0092] The above first transfer unit (120) can be placed between the one side (Z1) and the other side (Z2).

[0093] The above first transfer unit (120) can be placed between the 1-1 zone (Z1-1) and the 2-1 zone (Z2-1).

[0094] The first transfer unit (120) can transfer the material supplied from the supply unit (110) to the first bending unit (130).

[0095] An example of the first transfer unit (120) may be as shown in FIG. 7.

[0096] The above first transfer section (120) may include a flat section (121).

[0097] The above flat part (121) may be a device that releases the internal stress of the material supplied from the supply part (110) and sets the straightness.

[0098] The above flat portion (121) may include a horizontal roller (121-1) that releases the internal stress of the material existing in the direction in which the material is wound on the bobbin, as shown in FIG. 8, and a vertical roller (121-2) that sets the straightness of the material.

[0099] The above first transport unit (120) may also include a feeding unit that feeds the material according to the length of the production model.

[0100] The first transport section (120) may include a plurality of stripping sections (122: 122-1, 122-2, ...) arranged at intervals according to preset manufacturing standards, each stripping a specific portion of the material supplied from the supply section (110).

[0101] The above-mentioned plurality of peeling units (122) may be a device for peeling the outer skin of the material.

[0102] Each of the above plurality of peeling parts (122) may be a peeling mold that peels a specific portion of the material.

[0103] Here, the specific part may be a part according to the manufacturing standard.

[0104] An example of the above-mentioned multiple peeling parts (122) may be as shown in FIG. 9.

[0105] The above-mentioned plurality of peeling parts (122) can peel different parts of the material.

[0106] For example, the first shedding section (122-1) can shed a horizontal surface, and the second shedding section (122-2) can shed a vertical surface.

[0107] The above plurality of peeling sections (122) are arranged at intervals according to the manufacturing specifications, so that each can peel the material according to the manufacturing specifications.

[0108] The first transport unit (120) may include one or more cutting units (123) that cut the material peeled from the plurality of peeling units (122) according to the manufacturing specifications.

[0109] The above one or more cutting units (123) may be a device that cuts the material peeled from the plurality of peeling units (122) according to the manufacturing specifications.

[0110] The above one or more cutting sections (123) can cut a certain point of the material peeled from the plurality of peeling sections (122).

[0111] Here, the above-mentioned point may be a point according to the above-mentioned manufacturing standard.

[0112] In this way, the process in which the plurality of peeling parts (122) peel the material and the cutting part (123) cuts the peeled material may be as illustrated in FIG. 10.

[0113] As shown in (a) of Fig. 10, when the material of the angular movement line is located in the first peeling part (122-1), the first peeling part (122-1) can peel a part of the material as shown in (b) of Fig. 10, the second peeling part (122-2) can peel a part different from the part as shown in (c) of Fig. 10, and then the cutting part (123) can cut the peeled part of the material as shown in (d) of Fig. 10.

[0114] In this way, when the cutting section (123) cuts the material, the cut material can be transferred to the first bending section (130).

[0115] Meanwhile, when the manufacturing standard is changed while the first transfer unit (120) transfers the material supplied from the supply unit (110) to the first bending unit (130), the positions of the plurality of peeling units (122) and the one or more cutting units (123) can be changed according to the change criteria corresponding to the changed manufacturing standard.

[0116] That is, when the manufacturing standard is changed, the plurality of peeling parts (122) and the one or more cutting parts (123) may move and change their positions according to the change criteria.

[0117] For example, when the manufacturing standard is A and the gap between the first peeling part (122-1) and the second peeling part (122-2) is a [mm], and the manufacturing standard is changed to B, the first peeling part (122-1) and the second peeling part (122-2) may move and change their positions so that the gap between the first peeling part (122-1) and the second peeling part (122-2) is adjusted to b [mm] according to the B manufacturing standard.

[0118] Here, the change criterion may be a position change criterion of one or more of the plurality of peeling parts (122) and one or more cutting parts (123) preset in response to each of the manufacturing specifications.

[0119] The first transfer unit (120) may be moved in stages to change its position according to the change criteria when the manufacturing standard is changed.

[0120] That is, one or more of the plurality of peeling parts (122) and one or more cutting parts (123) may move in a certain movement order when the manufacturing standard is changed.

[0121] An example of one or more of the above-described multiple peeling sections (122) and one or more cutting sections (123) moving stepwise may be as shown in FIG. 11.

[0122] Figure 11 shows examples of cases where the manufacturing specification is changed from A to B, which is longer than A, in the order of (a), (b), (c), and (d). Cases where the manufacturing specification is changed from B to A can be performed in the reverse order as shown in Figure 11.

[0123] In the case where the manufacturing specifications are changed, the first transfer unit (120) may not move the plurality of stripping units (122) and the one or more cutting units (123) until the changed material (B) is delivered from the supply unit (110) as shown in (a) of FIG. 11.

[0124] In the case where the manufacturing standard is changed, the first transport unit (120) may, as shown in (a) of FIG. 11, have the first stripping unit (122-1) close to the supply unit (110) among the plurality of stripping units (122) strip the material (A) supplied from the supply unit (110) before the change in the manufacturing standard according to the manufacturing standard before the change and transfer it to the second stripping unit (122-2), and then, as shown in (b) of FIG. 11, the first stripping unit (122-1) may move.

[0125] That is, the first peeling unit (122-1) and the second peeling unit (122-2) maintain their positions until the material (B) after the manufacturing specification is changed is supplied from the supply unit (110), and the material (A) supplied from the supply unit (110) before the manufacturing specification is changed is peeled according to the manufacturing specification before the change, and when the material (B) after the manufacturing specification is changed is supplied from the supply unit (110) for the first time, the first peeling unit (122-1) can move so as to have a gap according to the changed manufacturing specification.

[0126] Accordingly, when the supply of material (B) begins after the manufacturing standard is changed from the supply unit (110), the interval between the first peeling unit (122-1) and the second peeling unit (122-2) is formed at an interval according to the changed manufacturing standard, so that the material (B) can be peeled according to the changed manufacturing standard.

[0127] In this case, the first bending portion (130) may bend the material stripped according to the manufacturing standard (A) before the change according to the manufacturing standard (A) before the change.

[0128] The first transport unit (120) may, when the manufacturing standard is changed, as shown in (b) of FIG. 11, the second stripping unit (122-2) strips the material (A) supplied from the first stripping unit (122-1) according to the manufacturing standard (A) before the movement of the first stripping unit (122-1) and transfers it to the one or more cutting units (123), and then, as shown in (c) of FIG. 11, the first stripping unit (122-1) and the second stripping unit (122-2) may move.

[0129] That is, the second peeling unit (122-2) may not move until the first peeling unit (122-1) moves and the peeled material (B) is first delivered from the first peeling unit (122-1) after the manufacturing specifications have been changed, and when the peeled material (B) is first delivered after the manufacturing specifications have been changed, the second peeling unit (122-2) may peel according to the changed manufacturing specifications and deliver it to one or more cutting units (123), and then move together with the first peeling unit (122-1).

[0130] In this case, the first peeling part (122-1) and the second peeling part (122-2) move the same distance to maintain the gap between the first peeling part (122-1) and the second peeling part (122-2), and the first bending part (130) can bend the material peeled according to the manufacturing standard (A) before the change according to the manufacturing standard (A) before the change.

[0131] Additionally, the one or more cutting sections (123) may also be moved and their positions changed according to changed manufacturing specifications.

[0132] Thereafter, the first peeling part (122-1) and the second peeling part (122-2) can move as shown in (d) of FIG. 11 after the second peeling part (122-2) peels the material twice according to the changed manufacturing standard (B).

[0133] Even in this case, the first peeling part (122-1) and the second peeling part (122-2) move the same distance to maintain the gap between the first peeling part (122-1) and the second peeling part (122-2), and the first bending part (130) can bend the material peeled according to the manufacturing standard (A) before the change according to the manufacturing standard (A) before the change.

[0134] Additionally, the one or more cutting sections (123) may also be moved and their positions changed according to changed manufacturing specifications.

[0135] That is, when the above manufacturing specifications are changed, materials that were processed according to the specifications before the change may be processed according to the specifications before the change.

[0136] Through this process, after the manufacturing specifications are changed, materials supplied before the change are stripped and bent according to the manufacturing specifications before the change, and materials supplied continuously are stripped and bent according to the changed manufacturing specifications, thereby preventing the generation of waste due to the change in the manufacturing specifications.

[0137] Meanwhile, at least one of the first bending portion (130) and the second bending portion (140) can change the bending setting according to the changed manufacturing standard after the position change of the plurality of peeling portions (122) and the one or more cutting portions (123) is completed according to the change criterion.

[0138] That is, when the manufacturing standard is changed, the first bending portion (130) and the second bending portion (140) may maintain the bending setting as the manufacturing standard (A) before the change until the position change of the plurality of peeling portions (122) and the one or more cutting portions (123) is completed, as shown in (d) of FIG. 11, and when the position change of the plurality of peeling portions (122) and the one or more cutting portions (123) is completed, the bending setting may be changed to the changed manufacturing standard (B).

[0139] Accordingly, the first bending portion (130) and the second bending portion (140) may bend the material received from the cutting portion (123) to the manufacturing standard (A) before the position change of the plurality of peeling portions (122) and the one or more cutting portions (123) is completed, and when the position change of the plurality of peeling portions (122) and the one or more cutting portions (123) is completed, the material received from the cutting portion (123) may be bent to the changed manufacturing standard (B).

[0140] The first bending portion (130) and the second bending portion (140) may be devices for forming the material into a hairpin.

[0141] The first bending portion (130) and the second bending portion (140) may be a bending mold for forming the material into a hairpin.

[0142] The first bending portion (130) and the second bending portion (140) can bend the material differently.

[0143] Each of the first bending portion (130) and the second bending portion (140) can bend the material according to the bending settings.

[0144] Here, the bending setting may be a setting for one or more criteria among the bending shape and number according to the manufacturing standard.

[0145] Each of the first bending part (130) and the second bending part (140) includes a gripper using an XYZ orthogonal robot and a cylinder, so that the input and output of the material can be performed automatically.

[0146] The above first bending portion (130) can be placed on one end (Z2-1) of the other side (Z2).

[0147] The above first bending section (130) can first bend the material transferred from the above first transfer section (120).

[0148] The above first bending portion (130) can bend the material into a V or U shape.

[0149] The first bending portion (130) can transfer the material to the second bending portion (140) after 2D bending the material.

[0150] The above second bending portion (140) can be placed at the other end (Z2-2) of the other side (Z2).

[0151] The second bending portion (140) can bend a material that has been first bent in the first bending portion (130) for a second time.

[0152] The above second bending portion (140) can bend the material into an R shape.

[0153] The second bending section (140) can 3D bend the material and then transfer it to the second transfer section (150).

[0154] The second transfer unit (150) may be placed between the one side (Z1) and the other side (Z2).

[0155] The second transport unit (150) can transport the material that has been bent a second time in the second bending unit (150) to the alignment unit (160).

[0156] The second transport section (150) may be formed so that some of the rails that transport the material to the alignment section (160) have a certain incline.

[0157] In this case, the above-mentioned constant slope can be formed in a form in which the height decreases as it goes toward the alignment part (160).

[0158] Examples of the second transfer unit (150) and the alignment unit (160) may be as shown in FIG. 12.

[0159] The above second transfer unit (150) may include an inspection unit (151).

[0160] The above inspection unit (151) may be placed at a position opposite to the position of the alignment unit (160) among the second transfer units (150).

[0161] The above inspection unit (151) can photograph the material bent by the second bending unit (140) and inspect the shape and dimensions of the bent material based on the photographing results.

[0162] The above inspection unit (151) may include one or more photographing devices.

[0163] That is, the above inspection unit (151) can perform a vision inspection on the bent material.

[0164] An example of the above inspection unit (151) may be as shown in Fig. 13.

[0165] The above inspection unit (151) receives the second bent material from the second bending unit (140), photographs the bent material, and based on the photographing results, can detect the shape and dimensions of the bent material as shown in FIG. 14.

[0166] The above inspection unit (151) can detect the shape and dimensions of the bent material from the photographing results, and compare the detection results with the inspection standards for the shape and dimensions according to the manufacturing standards to inspect the shape and dimensions of the bent material.

[0167] In this case, the inspection unit (151) can inspect the bending shape and one or more dimensions (A1 to A3, W1, W2, L1 to L4) of the bent material.

[0168] The above inspection unit (151) can compare the detection result with the inspection standard and inspect whether there is an abnormality in one or more of the shape and dimensions of the bent material according to the comparison result.

[0169] For example, it may be determined whether an abnormality has occurred in the result based on the error between the detection result and the inspection standard.

[0170] The above inspection unit (151) can inspect whether there is an abnormality in one or more of the shape and dimensions of the bent material, and transmit the inspection result to the control unit (200) of the manufacturing device (100), or one or more of the first bending unit (130) and the second bending unit (140).

[0171] In this way, when the second transfer unit (150) includes the inspection unit (151), at least one of the first bending unit (130) and the second bending unit (140) can correct the bending setting according to the inspection result of the inspection unit (151).

[0172] For example, if the inspection result shows that there is an abnormality in one or more of the shape and dimensions of the bent material, at least one of the first bending part (130) and the second bending part (140) may correct the bending settings so that the bending of the part corresponding to the abnormality is adjusted.

[0173] That is, at least one of the first bending portion (130) and the second bending portion (140) may feedback correct the bending setting according to the inspection result of the inspection portion (151).

[0174] The above inspection unit (151) can inspect the bent material and then transfer the inspected material to the alignment unit (160).

[0175] Meanwhile, if, as a result of the inspection, there is a material among the bent materials that does not meet the inspection criteria, the inspection unit (151) may determine that the material is defective and may separate and transport it separately without delivering it to the alignment unit (160).

[0176] The second transport section (150) may also include an ascending section (152).

[0177] The above-mentioned rising part (152) can be placed between the inspection part (151) and the alignment part (160).

[0178] The above-mentioned rising section (152) may be a device that raises and transports the material transported from the inspection section (151) to the rail height of the second transport section (150).

[0179] An example of the above-mentioned rising portion (152) may be as shown in FIG. 15.

[0180] When the material is placed on the hook-shaped gripper formed on the rising section (152), it is raised along a chain-shaped lift to a height where the rail of the second transport section (150) is located, transferred to the rail of the second transport section (150), and then moved downward along the slope of the second transport section (150) to be transferred to the alignment section (160).

[0181] The above alignment part (160) can be placed at the other end (Z1-2) of the one side (Z1).

[0182] The above alignment unit (160) can insert the material transferred from the second transfer unit (150) into an alignment jig, and align the material loaded on the alignment jig into a shape for manufacturing the hairpin.

[0183] The above alignment unit (160) may include a transmission unit (161).

[0184] The above-mentioned transfer unit (161) can be placed in an input port into which materials transferred from the second transfer unit (150) of the above-mentioned alignment unit (160) are input.

[0185] The above-mentioned transfer unit (161) can settle the material transferred from the second transfer unit (150) and place the settled material into the alignment unit (161).

[0186] That is, the transfer unit (161) can transfer the material transferred from the second transfer unit (150) to the alignment jig in the alignment unit (161).

[0187] An example of the above-mentioned transmission unit (161) may be as shown in Fig. 16.

[0188] The above-mentioned transfer unit (161) may include a settling unit (161a) on which a material transferred along the inclined rail of the second transfer unit (150) is placed, and a rotating unit (161b) that rotates the settling unit (161a) in the direction in which the alignment unit (160) is located when the material is placed on the settling unit (161a).

[0189] The above-mentioned fixing portion (161a) can have one or more materials fixed thereon.

[0190] The above rotating part (161b) can control the rotation and rotation speed of the above mounting part (161a).

[0191] The above-mentioned transmission unit (161) can cause the rotation unit (161b) to rotate the above-mentioned mounting unit (161a) by 1 pitch (90 degrees) when a material is mounted on the above-mentioned mounting unit (161a), so that the above-mentioned mounting unit (161a) is positioned on the upper portion of the alignment jig.

[0192] The above-mentioned transmission unit (161) can drop the material settled on the above-mentioned mounting unit (161a) in the direction of the above-mentioned alignment jig when the above-mentioned mounting unit (161a) is located on the upper portion of the above-mentioned alignment jig, thereby feeding the settled material into the above-mentioned alignment jig.

[0193] Thereafter, when a new material is transferred from the second transfer unit (150), the transfer unit (161) can cause the rotating unit (161b) to rotate the settling unit (161a) by -1 pitch (-90 degrees) so that the settling unit (161a) is positioned on the rail of the second transfer unit (150).

[0194] In this way, by feeding the material into the alignment unit (160) through the transmission unit (161), the material can be automatically and accurately and stably fed into the alignment unit (160), so that the alignment of the material in the alignment unit (160) can be performed accurately and stably.

[0195] Accordingly, the manufacturing of the hairpin can be carried out accurately and stably.

[0196] Meanwhile, the manufacturing device (100) described above may be implemented by being included in a hairpin manufacturing system (1000) (hereinafter referred to as a manufacturing system) according to an embodiment for manufacturing the hairpin, or may be implemented by applying the manufacturing system (1000).

[0204] The control unit (200) can change the bending settings of one or more of the first bending unit (130) and the second bending unit (140) according to the changed manufacturing specifications after moving the positions of the first peeling unit (122-1), the second peeling unit (122-2) and the cutting unit (123).

[0205] That is, when the control unit (200) changes the setting of the manufacturing standard, the bending setting of at least one of the first bending portion (130) and the second bending portion (140) may be changed according to the manufacturing standard after the positional movement of the first peeling portion (122-1), the second peeling portion (122-2) and the cutting portion (123) is completed.
