Description

Technical Field

[0001] This invention belongs to the field of automatic feeding machine technology, and particularly relates to a tape servo feeder and its usage method. Background Technology

[0002] In existing technologies, uncoilers typically use hydraulic or pneumatic cylinders to drive a set of arc-shaped plates to extend radially synchronously, thereby tensioning and fixing the inner hole of the coil. For example, Chinese invention patent CN215844953U, entitled "Coil Feeder," discloses a coil feeder comprising a coil position adjusting device for adjusting the height and position of the coil, a coil unloading device for clamping and rotating the coil, and a coil sorting integrated device for unloading, leveling, and feeding the coil. A guide rail is provided between the coil position adjusting device and the coil unloading device. The coil position adjusting device slides along the guide rail towards or away from the coil unloading device. The coil sorting integrated device is located next to the coil unloading device. The coil unloading device includes a housing, a variable-diameter shaft assembly, a first rotary motor, a coil clamping assembly, and a coil guiding assembly. The variable-diameter shaft assembly includes a shaft and a hydraulic cylinder.

[0003] However, the synchronous tensioning method in the aforementioned patented products has the following drawbacks: when the inner hole of the roll material becomes elliptical, locally concave, or irregularly deformed due to improper transportation or storage, the rigid arc-shaped sheet cannot deform accordingly and can only form localized contact with the inner wall of the roll material. This leads to uneven distribution of clamping force, which may cause insecure clamping and slippage during high-speed rotation, affecting production safety and quality. On the other hand, excessive local pressure may damage the inner wall of the roll material, resulting in product scrap. Summary of the Invention

[0004] The purpose of this invention is to provide a tape servo feeder and its usage method to solve the technical problem that existing tape servo feeders cannot clamp the inner hole of irregularly deformed rolls.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a tape servo feeder, comprising a feeding device, an unwinding device, and a leveling feeding device. The feeding device adjusts the distance between itself and the unwinding device through a position adjustment component. The leveling feeding device is located on the discharge side of the unwinding device. The unwinding device includes a body and a drive shaft. The drive shaft has several circumferential grooves, and a drive block is slidably disposed in each groove. The drive shaft has a drive unit inside, which moves axially within the drive shaft through a pushing mechanism and simultaneously drives the drive block to extend or retract radially along the groove. An arc-shaped piece is provided on the outer side of the drive block, and an adaptive adjustment component is provided between the arc-shaped piece and the drive block.

[0006] Preferably, the adaptive adjustment component includes several elastic elements, an adjustment groove is provided on the outer surface of the driving block, an adjustment part is provided below the arc-shaped piece, the arc-shaped piece is slidably disposed in the adjustment groove through the adjustment part, and the elastic elements are disposed between the driving block and the bottom of the adjustment groove.

[0007] Preferably, the drive block is provided with stops on both sides, and the inner wall of the drive shaft is provided with abutment portions on both sides of the slide groove. When the drive block is located in the slide groove, the stops correspond to the abutment portions, and a return spring is provided between them.

[0008] Preferably, the drive unit includes a push head, a push rod, and a power cylinder. The drive unit is fixed inside the machine body. One end of the push rod is connected to the push end of the power cylinder, and the other end is fixed to the push head. An arc-shaped guide surface is formed on the side of the push head away from the push rod.

[0009] Preferably, the drive shaft has an internal cavity, and the end of the drive block near the push seat head has an inclined arc surface that matches the arc-shaped guide surface. The push seat head moves axially along the internal cavity under the drive of the power cylinder and pushes each drive block to extend or retract from the outer surface of the drive shaft through the slide groove.

[0010] Preferably, the machine body is provided with a drive device, a transmission disk is fixedly installed on the transmission shaft, and the power shaft of the drive device is connected to the transmission disk to drive the transmission shaft to rotate on the machine body.

[0011] Preferably, the position adjustment component includes a base, a pushing part, and a power device. The base and the pushing part are slidably engaged by a guide rail and a pulley. The power device is used to drive the pushing part to move along the extension direction of the base to adjust the distance between the roll material and the unwinding device.

[0012] Preferably, the feeding device includes a support plate and an adjusting cylinder disposed on the pushing part. The upper surface of the support plate is V-shaped. The adjusting cylinder is fixedly installed inside the pushing part, and its pushing end extends to the outside of the pushing part and is connected to the support plate. The adjusting cylinder drives the support plate to move up and down to adjust the center hole position between the roll material and the drive shaft.

[0013] Preferably, one side of the machine body is provided with a support and guiding mechanism for carrying and guiding the roll material, and an unfolding member is provided on the upper side of the machine body. The roll material on the drive shaft can enter the unfolding member and unfold during rotation. The leveling and feeding device includes a leveling frame. One side of the leveling frame is provided with an arc-shaped feeding mechanism for receiving the roll material unfolded by the unfolding member. The leveling frame is provided with a roll material channel. Below the roll material channel is a roller assembly for pushing the roll material to move, and above it is a pressing mechanism for flattening the roll material.

[0014] This invention provides a method of using the above-mentioned tape servo feeder, comprising the following steps: S1: Hoist the roll material onto the support plate of the feeding device, adjust the distance between the feeding device and the uncoiling device through the position adjustment component, and drive the support plate to rise and fall through the adjustment cylinder so that the center hole of the roll material is aligned with the drive shaft; S2: The drive unit pushes the drive block to extend radially along the slide groove of the transmission shaft through the action of the push mechanism, so that the outer arc-shaped piece is tightly pressed against the inner ring of the roll material to complete the expansion and fixing. During this process, the adaptive adjustment component ensures that the arc-shaped piece is fully in contact with the surface of the inner ring of the roll material to adapt to the irregular and deformed inner ring of the roll material. S3: The drive unit starts, driving the transmission shaft and the fixed roll to rotate. The free end of the roll is unfolded by the unfolding member and enters the leveling and feeding device under the support and guidance of the supporting and guiding mechanism. S4: The roll material entering the leveling and feeding device is first received by the arc-shaped infeeding mechanism and guided into the roll material channel. Then, the upper pressing mechanism and the lower roller assembly work together to level the roll material and feed it by servo.

[0015] Compared with existing technologies, the present invention, through the above technical solution, has the following beneficial effects: By circumferentially setting several sliding grooves on the transmission shaft and setting driving blocks in all the sliding grooves, the driving blocks can extend or retract radially along the sliding grooves through the cooperation of the driving part and the pushing mechanism, thereby achieving clamping and fixing of the inner hole of the roll material. In this process, since the outer side of the driving block is connected to the arc-shaped piece through the adaptive adjustment component, when the driving part pushes the driving block to extend radially, the arc-shaped piece on its outer side can independently float slightly under the action of the adaptive adjustment component (such as an elastic element). This allows each arc-shaped piece to adaptively adjust its contact position and pressure according to the actual shape of the inner circle of the roll material (such as ellipticity, irregular shape due to local concavity), thereby achieving full and uniform contact with the irregular inner circle surface. This not only greatly enhances the reliability of the transmission and effectively prevents slippage during high-speed rotation, but also completely avoids damage to the inner wall of the roll material caused by rigid contact and local stress concentration, ensuring material quality.

[0016] Specifically, when the pushing mechanism pushes the drive unit to move axially within the inner cavity of the transmission shaft, the interaction between the arc-shaped guide surface on the drive unit and the inclined arc surface on one side of the drive block converts the axial thrust into a force that causes the drive block to move radially outward, thereby causing the arc-shaped pieces fixed on the drive block to extend radially. When a certain arc-shaped piece first contacts the protrusion of the inner hole of the roll material and is obstructed, the drive block at that point stops moving radially. However, the force used by the drive unit to push the drive block to release does not stop. Therefore, the arc-shaped piece located at the front end of the drive block in contact with the inner wall of the roll material will compress its adaptive adjustment component, causing the arc-shaped piece to retract into the drive block while still tightly adhering to the hole wall. Meanwhile, other unobstructed arc-shaped pieces continue to extend under the continuous push of the drive unit until all arc-shaped pieces are tightly adhering to the inner wall of the roll material, thus achieving adaptive tensioning of the irregular inner hole.

[0017] The above method solves the technical problem that when the inner hole of the roll material becomes elliptical, locally concave, or irregularly deformed due to improper transportation or storage, the rigid arc-shaped sheet of the existing roll servo feeder cannot deform accordingly and can only form local contact with the inner wall of the roll material.

Detailed Implementation

[0020] The following will refer to the appendices in the embodiments of the present invention. Figure 1-11 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0023] like Figure 1-11As shown: A roll servo feeder includes a feeding device 1 for adjusting the height and position of the roll, an unwinding device 2 for driving the roll to rotate and unwind, and a leveling feeding device 3 for processing the roll. The feeding device 1 adjusts its distance from the unwinding device 2 via a position adjustment component 4, thereby solving the problem of alignment between rolls of different outer diameters and the axis of the unwinding device 2 during feeding. The leveling feeding device 3 is located on the discharge side of the unwinding device 2. The unwinding device 2 includes a body 201 and a drive shaft 202 rotatably mounted within the body 201 via an internal bearing seat. The unwinding device 2 can clamp the roll and provide rotational power. The drive shaft 202 has several circumferential grooves 203, and each groove 203 has a slidably disposed drive block 204. The drive shaft 202 has a drive part 205 inside, which is fixed inside the body 201 and coaxial with the drive shaft 202. It can extend into the inner cavity of the drive shaft but does not rotate with the drive shaft 202. The drive part 205 moves axially in the drive shaft 202 through a pushing mechanism and simultaneously drives the drive block 204 to extend or retract radially along the groove 203. The outer side of the drive block 204 is provided with an arc-shaped piece 206, and an adaptive adjustment component is provided between the arc-shaped piece 206 and the drive block 204.

[0024] like Figure 4-6 As shown: The adaptive adjustment component includes an adjustment groove 207, an adjustment part 208, and an elastic element 5. The adjustment groove 207 is formed on the outer surface of the drive block 204. The adjustment part 208 is formed on the lower inner side of the arc-shaped piece 206. The adjustment part 208 is embedded in the adjustment groove 207 and can slide along the depth direction of the groove. In this embodiment, the elastic element 5 is a spring, which is placed between the body of the drive block 204 and the bottom of the adjustment groove 207 to provide a continuous outward preload force for the arc-shaped piece 206. In addition, a limiting part is provided at the opening of the adjustment groove 207. The length of the lower end of the adjustment part 208 located in the adjustment groove 207 is greater than the length of the opening of the adjustment groove 207. Therefore, when the adjustment part 208 moves upward, it is fixed in the adjustment groove 207 by the limiting part. At the same time, in order to increase the stability of the connection between the two, sliding grooves are provided on both sides of the adjustment groove 207, and sliders matching the sliding grooves are provided on both sides of the adjustment part 208.

[0025] In practical use, when the drive block 204 is pushed outward as a whole under the action of the drive unit 205, the arc-shaped piece 206 first contacts the inner wall of the roll material. If the inner hole of the roll material is perfectly circular, all the arc-shaped pieces 206 are evenly stressed, and the stroke of the compression elastic element 5 is basically consistent, achieving balanced tension. However, when the inner hole of the roll material has elliptical, concave, or irregular deformation, the arc-shaped pieces 206 in some areas will contact the inner wall first and experience greater resistance. The corresponding elastic element 5 will be compressed to a greater extent, allowing the arc-shaped piece 206 to retract to a certain extent relative to the drive block 204. The arc-shaped pieces 206 in other areas that are not in contact or have a smaller contact force continue to extend outward under the action of the elastic element 5 until all the arc-shaped pieces 206 are in full contact with the inner wall of the roll material. This method makes each arc-shaped piece 206 an independent floating unit, which can automatically adjust its position according to the local contour, thereby making the clamping force evenly distributed across the entire contact surface. This completely avoids indentations or damage to the inner wall of the roll material caused by localized contact, while ensuring maximum tension friction. It effectively prevents slippage or relative rotation between the roll material and the drive shaft during high-speed start-up, braking, or rotation, greatly improving the adaptability to defective incoming materials.

[0026] like Figure 8-9 As shown: To ensure reliable retraction of the drive block 204, stop blocks 209 are provided on both sides of the drive block 204. The stop blocks 209 and the drive block 204 are integrally formed, and abutment portions 210 are provided at corresponding positions on the inner wall of the transmission shaft 202. The return spring 211 is pre-compressed between the stop block 209 and the abutment portion 210. When the push seat head 212 retracts, the elastic potential energy stored in the return spring 211 is released, pushing the stop block 209, thereby driving the entire drive block 204 to retract radially inward. A spring mounting seat for placing the return spring 211 can be provided on the abutment portion 210 or the stop block 209.

[0027] like Figure 3 and Figure 7 As shown: The drive unit 205 includes a power cylinder 214 (in this embodiment, a hydraulic cylinder or an electric cylinder), a push rod 213, and a push head 212. One end of the push rod 213 is connected to the piston rod of the power cylinder 214, and the other end extends into the inner cavity of the drive shaft 202 and is fixed to the push head 212. The front end of the push head 212 is designed as an arc-shaped guide surface. Correspondingly, the inner end of each drive block 204 (the end closest to the push head 212) is machined with a sloping arc surface that matches the aforementioned arc-shaped guide surface.

[0028] By utilizing the combination of inclined planes and arc-shaped guide surfaces, multiple radial motion units can be synchronously driven by a single axial power source. The structure is compact, and the power transmission is efficient and smooth. The reset spring 211 ensures that the tensioning mechanism can automatically, quickly, and reliably reset after being compressed, avoiding the risk of jamming and improving the stability and response speed of the equipment operation.

[0029] like Figure 10-11 As shown: The transmission shaft 202 has an inner cavity. The end of the drive block 204 near the push seat head 212 has an inclined arc surface that matches the arc-shaped guide surface. The push seat head 212 moves axially along the inner cavity under the drive of the power cylinder 214 and pushes each drive block 204 to extend or retract from the outer surface of the transmission shaft 202 through the slide groove 203.

[0030] When the power cylinder 214 actuates, it drives the push head 212 to move axially within the cavity of the transmission shaft 202 via the push rod 213. The arc-shaped guide surface of the push head 212 contacts the inclined arc surface of the drive block 204. Utilizing the principle of the inclined plane, the axial thrust of the push head 212 is converted into the radial thrust of the drive block 204, forcing all drive blocks 204 to extend outward synchronously along the slide groove 203. Conversely, when the power cylinder 214 returns, the push head 212 retracts, relieving pressure on the drive blocks 204.

[0031] like Figure 3 As shown: The drive unit 215 is fixedly mounted on the machine body 201. The drive unit 215 is a servo drive motor, and its power output shaft is connected to the transmission disc 216 fixed on the transmission shaft 202 through a coupling, gear set or belt. When the drive unit 215 is started, the entire transmission shaft 202 and the tensioned roll on it will rotate together to realize unwinding and feeding.

[0032] like Figure 1-2 As shown: The position adjustment component 4 includes a base 401 fixed to the ground, a pusher 402 movable on the base, and a power unit (not fully shown in the figure) providing power. In this embodiment, a servo motor with lead screw drive or an electric push rod with a tank track structure can be used. A precise guide rail is provided on the base 401, and a pulley is correspondingly provided at the bottom of the pusher 402. The two form a sliding engagement to ensure that the pusher 402 can move smoothly and linearly along the extension direction of the base 401. The power unit is driven by the pusher 402, controlling its forward or backward movement, thereby precisely adjusting the distance between the feeding device 1 and the unwinding device 2 to accommodate rolls of different widths. Simultaneously, the pusher 402 can also mount the rolls onto the drive shaft 202 of the unwinding device 2 without manual intervention.

[0033] like Figure 1-2As shown: The feeding device 1 is directly mounted on the pushing section 402. The feeding device 1 includes a support plate 101 and one or more adjusting cylinders 102. The upper surface of the support plate 101 is designed as a V-shaped surface. This structure can automatically center the roll material placed on it, allowing it to naturally roll to the bottom of the V-shaped groove under gravity, initially positioning the lateral center of the roll material. The cylinder body of the adjusting cylinder 102 is fixedly mounted on the internal structure of the pushing section 402, and its piston rod (i.e., the pushing end) extends vertically upward and is fixedly connected to the bottom of the support plate 101. By controlling the extension and retraction of the piston rod of the adjusting cylinder 102, the entire support plate 101 and the roll material on it can be driven to move vertically up and down.

[0034] Through the above methods, the position adjustment component 4 and the feeding device 1 work together to achieve precise positioning of the roll material in both horizontal and vertical directions. Specifically, by adjusting the spacing through horizontal movement, ample operating space is provided for roll materials of different diameters, enhancing the versatility of the equipment. At the same time, it can also drive the roll material to complete the threading action. In addition, the V-shaped support plate 101 realizes the automatic initial centering of the roll material, simplifying the operation. Finally, by adjusting the vertical lifting of the cylinder 102, the center height of the roll material can be finely adjusted so that its center hole is precisely aligned with the axis of the drive shaft 202 of the unwinding device 2, laying the foundation for the threading and tightening operations. The whole process is highly automated, significantly reducing the difficulty and labor intensity of manual adjustment.

[0035] like Figure 1-2 As shown: A supporting and guiding mechanism 6 is provided on one side of the machine body 201 for carrying and guiding the roll material. An unfolding member 7 is provided on the upper side of the machine body 201. The roll material on the drive shaft 202 can enter the unfolding member 7 and unfold during rotation. The leveling and feeding device 3 includes a leveling frame 301. An arc-shaped feeding mechanism 302 is provided on one side of the leveling frame 301 for receiving the roll material unfolded by the unfolding member 7. A roll material channel is provided on the leveling frame 301. A roller assembly 303 for pushing the roll material is provided below the roll material channel, and a pressing mechanism 304 for flattening the roll material is provided above. Specifically, the arc-shaped feeding mechanism 302 of the leveling and feeding device 3 is used to gently receive the material from the unfolding member 7 and introduce it into the roll material channel formed by the leveling frame 301. Inside the channel, multiple sets of adjustable pressure pressing mechanisms 304 (such as leveling upper dies) are provided above, and roller assemblies 303 driven by servo motors are provided below. The clamping mechanism 304 is responsible for flattening the bent strip, while the roller assembly 303 provides precise traction force to achieve servo feeding, providing flat and fixed-length material for subsequent stamping and other processes. The aforementioned supporting and guiding mechanism 6, unfolding component 7, and leveling and feeding device 3 are all existing technologies and will not be described in detail here.

[0036] The entire process, from uncoiling to leveling and feeding, is seamlessly integrated and highly automated through the aforementioned components. The drive unit 215 provides stable rotational power. The supporting guide mechanism 6 and the unfolding component 7 ensure a smooth transition of the strip material from a coiled state to a flat state, preventing twisting and scratches. The leveling and feeding device 3 ultimately ensures the flatness and feeding accuracy of the delivered material, meeting the production requirements of high-precision machining.

[0037] The present invention also provides a method for using the above-mentioned tape servo feeder, the method specifically including the following steps: S1: The roll material to be processed is stably placed on the V-shaped support plate 101 of the feeding device 1 using a hoisting device. The power unit of the position adjustment component 4 is activated, driving the pusher 402 to move along the guide rail of the base 401, thereby adjusting the horizontal distance between the feeding device 1 and the uncoiling device 2, so that the end face of the roll material is basically aligned with the axial position of the drive shaft 202. Subsequently, the adjustment cylinder 102 is activated, driving the support plate 101 to perform precise vertical lifting and lowering movements. Through the automatic centering characteristics of the V-shaped support surface, the center hole of the roll material is completely aligned with the center axis of the drive shaft 202 of the uncoiling device 2. Finally, the pusher 402 is driven to sleeve the roll material onto the drive shaft, completing the positioning and installation of the roll material. S2: The power cylinder 214 of the drive unit 205 starts working, driving the push head 212 axially forward in the inner cavity of the transmission shaft 202 via the push rod 213. The arc-shaped guide surface of the push head 212 interacts with the oblique arc surface of each drive block 204, converting the axial thrust into radial thrust, and simultaneously pushing all drive blocks 204 outward along the slide groove 203. The drive block 204 drives the arc-shaped piece 206 on its outer side to expand radially until all arc-shaped pieces 206 are in contact with the inner surface of the roll material. During this process, the adaptive adjustment component adjusts. When encountering an irregular inner roll material, the arc-shaped piece 206 with greater contact resistance will compress the corresponding elastic element 5, producing adaptive retraction, while the arc-shaped piece 206 with less contact resistance will remain extended under the continuous action of the elastic element 5, thereby achieving full fit between all arc-shaped pieces 206 and the inner contour of the roll material, forming a uniformly distributed clamping force, completing the reliable fixation of the roll material, and effectively avoiding slippage and damage to the inner wall; S3: The drive unit 215 starts, driving the drive shaft 202 and the fixed roll material to rotate synchronously via the transmission disc 216. Under the action of centrifugal force and material rigidity, the free end of the roll material gradually detaches from the roll and enters the working area of ​​the unfolding component 7. The unfolding component 7 initially unfolds the rolled material into a straight state, and under the continuous support and guidance of the supporting and guiding mechanism 6, it maintains a stable material shape and smoothly enters the feed inlet of the leveling and feeding device 3, completing the transition from roll material to strip material; S4: The strip material entering the leveling and feeding device 3 is first received by the arc-shaped inlet mechanism 302. This mechanism guides the strip material into the roll material channel of the leveling frame 301 with a smooth arc trajectory, avoiding sharp bends that scratch the material surface. In the roll material channel, the strip material passes through under the combined action of the elastic pressure of the upper clamping mechanism 304 and the rotational traction force of the lower roller assembly 303. The clamping mechanism 304 applies adjustable pressure to the strip material, eliminating its original bending stress and restoring it to a flat state; under the control of the servo drive system, the roller assembly 303 accurately conveys the leveled strip material forward at a preset feeding step and speed, providing high-quality flat material for subsequent stamping, shearing and other processing steps.

The base (401) and the pusher (402) are slidably coupled through a guide rail and a pulley. The power device is used to drive the pusher (402) to move along the extension direction of the base (401) to adjust the distance between the roll material and the unwinding device (2).

8. A tape servo feeder according to claim 7, characterized in that: The feeding device (1) includes a support plate (101) and an adjusting cylinder (102) disposed on the pushing part (402). The upper surface of the support plate (101) is V-shaped. The adjusting cylinder (102) is fixedly installed inside the pushing part (402). Its pushing end extends to the outside of the pushing part (402) and is connected to the support plate (101). The adjusting cylinder (102) drives the support plate (101) to move up and down to adjust the center hole position between the roll material and the drive shaft (202).

9. A tape servo feeder according to claim 1, characterized in that: The machine body (201) has a support and guide mechanism (6) on one side for carrying and guiding the roll material. The machine body (201) has an unfolding member (7) on the upper side. The roll material on the drive shaft (202) can enter the unfolding member (7) and unfold during rotation. The leveling and feeding device (3) includes a leveling frame (301). The leveling frame (301) has an arc-shaped feeding mechanism (302) on one side for receiving the roll material unfolded by the unfolding member (7). The leveling frame (301) has a roll material channel. The roll material channel has a roller assembly (303) for pushing the roll material to move below it and a pressing mechanism (304) for flattening the roll material above it.

10. A method of using a tape servo feeder, characterized in that: Specifically, the following steps are included: S1: Hoist the roll material onto the support plate (101) of the feeding device (1), adjust the distance between the feeding device (1) and the unwinding device (2) by the position adjustment component (4), and drive the support plate (101) to rise and fall by the adjustment cylinder (102) so that the center hole of the roll material is aligned with the drive shaft (202); S2: The drive unit (205) pushes the drive block (204) to extend radially along the slide groove (203) of the transmission shaft (202) through the action of the push mechanism, so that the outer arc-shaped piece (206) is tightly pressed against the inner ring of the roll material to complete the expansion and fixing. During this process, the adaptive adjustment component ensures that the arc-shaped piece (206) is fully in contact with the inner ring surface of the roll material to adapt to the irregular and deformed inner ring of the roll material. S3: The drive unit (215) starts, driving the transmission shaft (202) and the fixed roll to rotate. The free end of the roll is unfolded by the unfolding member (7) and enters the leveling and feeding device (3) under the support and guidance of the supporting and guiding mechanism (6). S4: The roll material entering the leveling and feeding device (3) is first received by the arc-shaped feeding guide mechanism (302) and introduced into the roll material channel. Then, the upper pressing mechanism (304) and the lower roller assembly (303) work together to level the roll material and feed it by servo.
