Description

Technical Field

[0001] The present invention relates to the technical field of stator assembly, and particularly to a stator assembly machine. Background Art

[0002] A stator assembly machine is a key device in motor manufacturing. Its function is to integrate a base and a stator into one through a pressing operation. In this process, a certain pressure is applied to make the two closely combined, thereby completing an important process of stator assembly.

[0003] However, there are still some problems with the existing stator assembly machines: First, during the pressing process, the guiding mechanism of the device can only achieve the clamping and positioning of the base, but there is a lack of positioning measures for the stator. Currently, it relies on manual placement and fine-tuning of the stator. After placing it above the base and then performing the pressing, from the perspective of manual adjustment, this is an extremely time-consuming process. In large-scale production, each stator needs to be manually placed and fine-tuned, which greatly increases the assembly time of a single stator, thereby reducing the overall production efficiency. At the same time, if the stator is pressed without being aligned with the base, it will cause damage to the stator during the pressing process, resulting in local deformation, breakage, etc. of the iron core, winding, or insulating layer of the stator. This will not only make the current stator a defective product or even a waste product, but also increase the production cost.

[0004] Secondly, during the forming process of the stator iron core, insulating ring, and winding, due to minute mechanical deviations, there are certain deviations in the quantity and quality of the windings on both sides of the stator iron core and the insulating ring. Under normal circumstances, when there is a slight deviation in the quantity and quality of the windings, the impact on the overall performance of the motor is relatively small because the design of the motor usually has a certain degree of fault tolerance. A small amount of winding deviation can be compensated by the functions of other parts within the normal operating range of the motor. However, when there are such deviations in quantity and quality, during the pressing process, since the pressing force is uniform, the uniform pressing force will cause different degrees of deformation of the windings on both sides. One side deforms more and the other side deforms less, and this deformation difference will have a great negative impact on the magnetic field distribution of the motor.

[0005] Magnetic field distribution is one of the key factors for the normal operation of a motor. Uneven magnetic field distribution will cause the torque of the motor to be unstable. For example, when the motor drives a load to operate, there will be intermittent power shortages or speed fluctuations, affecting the normal operation of the equipment. From the perspective of energy conversion, uneven magnetic field distribution will reduce the energy conversion efficiency of the motor, resulting in more energy losses during the conversion process from electrical energy to mechanical energy, manifested as an increase in the heat generation of the motor. This not only wastes energy, but also the long-term overheating will accelerate the aging of the insulating materials inside the motor and shorten the service life of the motor.

[0006] Second, in the structure of the motor, after the stator core, short-circuit ring, insulating ring, and winding are assembled into the stator in the previous pressing process, the lead wire is a key part for connecting the internal winding of the stator to the external circuit. It plays the role of transmitting the electrical energy generated in the stator to the external circuit or receiving electrical energy input from the external circuit into the stator winding. During the pressing process, since there is a lead wire at the top of the stator, the operator needs to hold the lead wire by hand to prevent it from being accidentally pressed. In the prior art, in order to improve efficiency, the operator often holds the lead wire with one hand and performs the operation of feeding the base or the stator with the other hand. As a result, when the operator is distracted, the attention cannot be fully concentrated on the action of picking up the base. When the operator reaches out to pick up the base, due to multitasking, the body coordination and the ability to control the movement will decline, which is likely to cause the base to slip and injure the feet or other body parts. At the same time, holding the lead wire by hand will limit the operator's activity range and flexibility. In the case of limited operating space, it is easier to collide with surrounding equipment and tools, resulting in accidental injuries. Moreover, distracted operation will cause the operator to ignore the potential hazards in the surrounding environment, such as obstacles on the ground or other operating equipment, thus increasing the possibility of safety accidents.

[0007] For this reason, the present invention proposes a stator assembly machine. Summary of the Invention

[0008] The purpose of the present invention is to provide a stator assembly machine to solve the problems raised in the above background technology.

[0009] To achieve the above purpose, the present invention provides the following technical solution: A stator assembly machine includes a workbench and a driving cylinder. An arc-shaped pressing block is installed at the bottom of the output shaft of the driving cylinder. A sliding platform is installed above the workbench. A circular convex clamping seat is slidably connected inside the sliding platform. An elastic anti-deformation component for guiding the stator and preventing uneven deformation of the winding is arranged above the workbench. The elastic anti-deformation component includes a plurality of second hollow sleeves that limit the stator through their own guiding, a plurality of anti-deformation springs, and a plurality of pressing plates that ensure the same degree of winding deformation through the elastic action of the anti-deformation springs. One side of the pressing plate close to the center of the circular convex clamping seat is recessed inward.

[0010] Preferably, the elastic anti-deformation component further includes a plurality of first hollow sleeves fixedly connected to the top of the circular convex clamping seat. The second hollow sleeves are all fixedly connected to the top of the first hollow sleeves. Guide plates are slidably connected inside the second hollow sleeves. The pressing plates are all slidably connected inside the first hollow sleeves. The anti-deformation springs are all fixedly connected between the pressing plates and the inner walls of the first hollow sleeves and between the guide plates and the inner walls of the second hollow sleeves. Support ribs are fixedly connected to the outer surfaces of the first hollow sleeves and the second hollow sleeves.

[0011] Preferably, the top and bottom of the pressing plate and the guiding plate are both rounded, the sides of the pressing plate and the guiding plate close to the center of the circular convex clamping seat are both in contact with the stator, and the support ribs are located on the sides of the first hollow sleeve and the second hollow sleeve away from the pressing plate.

[0012] Preferably, guiding platforms are respectively fixedly connected to the top of the workbench and on both sides of the sliding platform. Clamping blocks are slidably connected to the outer surfaces of the guiding platforms. Matching grooves are respectively formed in the middle parts of the clamping blocks. Matching rods are symmetrically and fixedly connected to the outer surfaces of the arc-shaped pressing blocks on the output shafts of the driving cylinders. The bottoms of the matching rods are slidably connected to the interiors of the matching grooves.

[0013] Preferably, the sides of the clamping blocks close to the sliding platform are all set as concave arc surfaces. The matching grooves extend to the top of the workbench. The middle parts of the matching rods are all inclined. Taking the middle part as the demarcation line, the upper and lower ends are staggered and parallel. The matching groove is composed of two right trapezoidal grooves, and the short sides of the two right trapezoidal grooves are in contact with each other, but their hypotenuses are arranged in opposite directions.

[0014] Preferably, a bearing platform is installed on the top of the workbench. The driving cylinder is fixedly connected to the outer surface of the bearing platform, and its output shaft penetrates through the bearing platform. An electric control panel is installed on the top of the bearing platform.

[0015] Preferably, a driving mechanism for driving the circular convex clamping seat to move is built in the sliding platform. The electric control panel electrically controls the start and stop of the driving cylinder and the driving mechanism.

[0016] Preferably, a pin for fixing the base is installed on the top of the circular convex clamping seat. The circular convex clamping seat has a disk-shaped bottom and a cylindrical convex top.

[0017] Preferably, a lead wire clamping and connecting assembly for preventing the lead wire from being squeezed by the arc-shaped pressing block is arranged above the circular convex clamping seat. The lead wire clamping and connecting assembly includes two convex platforms. The convex platforms are symmetrically and fixedly connected to the top of the circular convex clamping seat. A convex strip is fixedly connected to the top of the circular convex clamping seat. Clamping blocks are symmetrically slidably connected to the outer surface of the convex strip. Card slots are respectively formed in the sides of the two clamping blocks close to each other. A return spring is fixedly connected between each clamping block and the convex platform.

[0018] Preferably, the lead wire clamping and connecting assembly is symmetrically arranged with the middle part of the convex strip as the center line. The two clamping blocks are both arranged on the side closest to the stator winding. The edges of the card slots are all rounded. At the same time, the tops of the clamping blocks are trapezoidal.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention effectively solves the problem of excessive winding deformation difference in the motor stator pressing process in the prior art by introducing the elastic action mechanism of the pressing plate and the anti-deformation spring, and the pressing plate provides stable support and positioning for the stator. At the same time, the anti-deformation spring can play a role of buffering and uniformly distributing the pressing force during the pressing process through its own elasticity. The combined use of the two not only prevents the winding deformation difference caused by uniform pressing force, but also helps to improve the assembly accuracy and stability of the stator.

[0020] Compared with the prior art, the present invention eliminates the tedious steps of manual placement and fine-tuning of the stator through an elastic anti-deformation component, reduces dependence on manual operation, thereby greatly improving production efficiency and shortening the assembly time of a single stator. Secondly, the elastic action mechanism of the pressing plate and the anti-deformation spring can effectively prevent the winding from producing excessive deformation differences during the pressing process, thereby greatly reducing the problem of uneven magnetic field distribution caused by deformation differences, thereby improving the overall performance and energy conversion efficiency of the motor.

[0021] Among them: the concave surface of the pressing plate can limit the deformation of the winding, that is, when the winding is subjected to the pressing force, due to the existence of the concave arc surface, its deformable space is effectively constrained within a certain range.

[0022] Among them: During the assembly and pressing process of the stator, the winding needs to be adjusted within a certain range or adapt to the slight displacement of other components, and the design of the transition radius of the pressing plate and the guide plate is like laying a "smooth track" for the movement of the winding. The winding can easily slide along the radius edge, avoiding unnecessary jamming and damage.

[0023] While achieving the above-mentioned beneficial effects, the present invention also has the following advantages: First, the stator is limited by a plurality of second hollow sleeves and guide plates, which greatly simplifies the positioning operation of the stator. The operator only needs to insert the stator between the plurality of second hollow sleeves to achieve positioning. In the process of large-scale production of motors, each slight reduction in stator positioning time can be accumulated to produce significant effects. Since the operator can quickly complete the positioning of the stator, the entire assembly process is smoother, reducing the production bottleneck caused by stator positioning, thereby improving the overall production efficiency.

[0024] Second: when the stator is taken out after pressing, the anti-deformation spring resists the winding through the guide plate and the pressing plate, causing it to briefly enter a plastic state. That is, the elastic extension of the anti-deformation spring's resistance to the winding is like a fine-tuning, which can properly correct these tiny deformations and prevent these small deformations from gradually accumulating during subsequent use and causing greater damage to the winding, thereby extending the service life of the winding.

[0025] Thirdly, during the movement of the mating rod, the interference with the mating groove drives the clamping block to clamp the stator, thereby saving the cost of two driving cylinders required to clamp the stator in the prior art. In traditional motor manufacturing technology, the use of two driving cylinders to achieve the clamping and pushing function of the stator not only requires the purchase and maintenance of these driving cylinder equipment, but also requires more space and energy. However, in the present invention, the same effect can be achieved through the clever coordination between the mating rod, the mating groove and the clamping block, thereby reducing the investment cost of the equipment. In addition, compared with the complex operation and control system using two driving cylinders, the linkage method of the mating rod, the mating groove and the clamping block is more direct and simple, and the operator does not need to operate and debug the two independent driving cylinders separately, thereby reducing the possibility of operating errors.

[0026] 2. The present invention pulls the two leads into the two blocks when the operator places the stator on the slide platform, and the leads can be limited by the slots. First of all, under this improvement measure, the leads are effectively limited, and the operator does not need to hold the leads to prevent them from being pressed by mistake, which eliminates a series of safety hazards caused by holding the leads. At the same time, the operator does not need to be distracted and can focus all his attention on operations such as taking the base, which greatly reduces the possibility of ignoring dangerous factors in the surrounding environment, reduces the occurrence of safety accidents, and helps to create a safer working environment.

[0027] Secondly, the steps of pulling the lead wire into the clamping block and limiting the lead wire by the clamping slot take less time. Compared with the distracting operation method in the prior art where the operator holds the lead wire in one hand and loads the base or stator with the other hand, the improvement measures of the present invention allow the operator to focus more on a single operation task, reduce interference factors in the operation, thereby making the operation smoother and improving overall operating efficiency.

[0028] Finally, since the lead clamping assembly simplifies the operating process, the operator does not need to perform complex coordination actions between holding the lead and picking up the base or stator. In the prior art, performing other operations while holding the lead requires the operator to have a high degree of coordination. The improvements of the present invention make the operation more intuitive and simple, and reduce the requirements for the operator's operating skills.

[0029] Among them: the edge of the card slot has a transition rounded corner and the top of the card block is a trapezoidal shape, which allows the lead to easily enter and exit the card slot. During operation, the trapezoidal slope and rounded corners provide guidance and buffering for the lead, reducing the difficulty of operation and increasing the operation speed. At the same time, it also avoids possible damage to the lead when entering and exiting, ensuring the integrity of the lead.

[0030] Wherein: the clamping block is connected to the boss through a reset spring, and the reset spring can provide elastic buffer to ensure the stability of the limiting effect of the clamping block on the lead wire. Brief Description of the Drawings

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] It should be noted that the stator pressing mentioned in the text refers to the pressing of the stator and the base, and the stator has completed the installation of the insulating ring, short-circuit ring, lead wire, and winding in the previous process. The installation of the stator belongs to the prior art and will not be elaborated here. Therefore, the present invention is improved for the pressing process of the stator and the base.

[0046] Embodiment 1: As Figures 1 to 5 shown, a stator assembly machine includes a workbench 11 and a driving cylinder 12. An arc-shaped pressing block is installed at the bottom of the output shaft of the driving cylinder 12. A sliding platform 13 is installed above the workbench 11. A circular convex clamping seat 14 is slidably connected inside the sliding platform 13. An elastic anti-deformation component 2 for guiding the stator and preventing uneven deformation of the winding is arranged above the workbench 11. The elastic anti-deformation component 2 includes a plurality of second hollow sleeves 22 that limit the stator through their own guiding, a plurality of anti-deformation springs 25, and a plurality of pressing plates 23 that ensure the uniform deformation degree of the winding through the elastic action of the anti-deformation springs 25. One side of the pressing plate 23 close to the center of the circular convex clamping seat 14 is recessed inward.

[0047] As Figure 5 shown, the elastic anti-deformation component 2 further includes a plurality of first hollow sleeves 21 fixedly connected to the top of the circular convex clamping seat 14. The second hollow sleeves 22 are all fixedly connected to the top of the first hollow sleeves 21. A guide plate 24 is slidably connected inside each of the second hollow sleeves 22. The pressing plates 23 are all slidably connected inside the first hollow sleeves 21. The anti-deformation springs 25 are all fixedly connected between the pressing plates 23 and the inner walls of the first hollow sleeves 21 and between the guide plates 24 and the inner walls of the second hollow sleeves 22. Support ribs 26 are fixedly connected to the outer surfaces of the first hollow sleeves 21 and the second hollow sleeves 22.

[0048] As Figures 6 to 7 shown, guide platforms 27 are respectively fixedly connected to both sides of the sliding platform 13 on the top of the workbench 11. Clamping blocks 28 are slidably connected to the outer surfaces of the guide platforms 27. A mating groove 29 is formed in the middle of each clamping block 28. Mating rods 210 are symmetrically fixedly connected to the outer surface of the arc-shaped pressing block on the output shaft of the driving cylinder 12. The bottom of the mating rods 210 is slidably connected inside the mating groove 29.

[0049] It should be noted that the top and bottom ends of the pressing plate 23 and the guiding plate 24 are both provided with rounded corners. The sides of the pressing plate 23 and the guiding plate 24 close to the center of the circular convex clamping seat 14 are both in contact with the stator. The support ribs 26 are located on the sides of the first hollow sleeve 21 and the second hollow sleeve 22 away from the pressing plate 23. The sides of the clamping blocks 28 close to the sliding table 13 are all provided with concave arc surfaces. The mating groove 29 extends to the top of the workbench 11. The middle parts of the mating rods 210 are all inclined, and with the middle part as the demarcation line, their upper and lower ends are offset and parallel. The mating groove 29 is composed of two right trapezoidal grooves, and the short sides of the two right trapezoidal grooves are in contact with each other, but their hypotenuses are arranged in opposite directions. A carrying platform 15 is installed on the top of the workbench 11. The driving cylinder 12 is fixedly connected to the outer surface of the carrying platform 15, and its output shaft penetrates through the carrying platform 15. An electric control panel 16 is installed on the top of the carrying platform 15. A driving mechanism for driving the circular convex clamping seat 14 to move is built in the sliding table 13. The electric control panel 16 electrically controls the start and stop of the driving cylinder 12 and the driving mechanism. A pin for fixing the base is installed on the top of the circular convex clamping seat 14. The circular convex clamping seat 14 has a disk-shaped bottom and a cylindrical protrusion at the top. The driving mechanism can be implemented as an external micro cylinder installed inside the sliding table 13. The output shaft of the external micro cylinder is fixedly connected to the bottom of the circular convex clamping seat 14. The stator can be installed on the top of the circular convex clamping platform.

[0050] Specifically, the operator first places the base on the top of the circular convex clamping seat 14 to ensure that the base is placed stably and accurately. Subsequently, the operator holds the stator by hand and places the two sides of the stator with windings between several guiding plates 24. Since the rear end of the guiding plate 24 is connected to the anti-deformation spring 25, and the anti-deformation spring 25 is an elastic element, this structural design enables the operator not to need to additionally adjust the posture of the stator during the process of placing the stator. That is, the elasticity of the anti-deformation spring 25 can adaptively adjust the posture of the stator. It can accommodate and correct the position deviation of the stator through its own elastic deformation according to the initial position and angular difference when the stator is placed, ensuring that the stator can be accurately placed at the predetermined position.

[0051] When the stator is placed, the operator manipulates the electric control panel 16 to start the built-in driving mechanism of the slide platform 13 through electrical control. The driving mechanism starts to work, and its output shaft is fixedly connected to the bottom of the convex clamping seat 14, thereby driving the convex clamping seat 14 to move below the output shaft of the driving cylinder 12. At this time, the driving cylinder 12 is started, and the output shaft of the driving cylinder 12 will drive the matching rod 210 fixedly connected to its outer surface to move synchronously during the downward movement. Since the middle part of the matching rod 210 is inclined and the matching groove 29 is composed of two right-angled trapezoidal grooves, its structural characteristics make the matching rod 210 bend in the middle part of the matching rod 210 and the middle part of the matching groove 29 during the movement. Under the interaction of the bending of the matching rod 210 and the bending of the matching groove 29, the movement of the driving cylinder 12 will drive the clamping block 28 to move toward the side close to the stator through the matching groove 29.

[0052] Because the side of the clamping block 28 close to the slide platform 13 is set to be a concave arc surface, when the clamping block 28 moves toward the stator, the movement of the clamping block 28 will cause the two sides of the stator insulation ring protrusion to press against the arc surface of the clamping block 28. In this process, the original protrusion shape of the insulation ring gradually becomes a round surface under the action of the clamping block 28.

[0053] Next, the output shaft of the driving cylinder 12 continues to descend and begins to press the stator into the base. During the pressing process, the winding on the surface of the stator will slide downward along the guide plate 24. At the same time, since the insulating ring is restricted by the clamping block 28 and the raised side of the insulating ring will also enter the base during the pressing process, the winding is not only subjected to the pressure of the driving cylinder 12, but also to the restricting force of the insulating ring. The existence of this dual force causes the winding to come into contact with the pressing plate 23 during the downward deformation and sliding process.

[0054] When the winding contacts the pressing plate 23, due to the elastic characteristics of the anti-deformation spring 25, elastic contraction will occur and drive the pressing plate 23 to slide toward the inside of the first hollow sleeve 21. During this process, the anti-deformation spring 25 and the pressing plate 23 will adaptively change the contraction degree of the anti-deformation spring 25 based on the elastic force of the anti-deformation spring 25 and the mass of the winding itself, that is, the elastic force of the anti-deformation spring 25 will be adjusted according to the pressure applied to it by the winding, and the mass of the winding affects its inertia and downward pressure during the pressing process. Through this adaptive adjustment mechanism, the deformation space of the winding can be limited, thereby ensuring that the deformation of the winding is maintained in a relatively equal state. This means that during the entire pressing process, the deformation degree of the winding in various parts can remain relatively consistent, avoiding motor performance problems that may be caused by excessive or small local deformation, such as uneven magnetic field distribution.

[0055] When the stator is pressed, the driving cylinder 12 drives the matching rod 210 to rise. During this process, the matching rod 210 resists and drives the clamping block 28 to reset. At this time, the operator can remove the stator from the top of the convex seat 14. During the removal process, the pressing plate 23 and the guide plate 24 will also apply a certain pressure to the stator winding through the anti-deformation spring 25, and this pressure can temporarily shape the stator winding, thereby preventing the stator from deforming during the rapid removal process. After the pressing is completed, the stator winding is in a compressed state. If it suddenly loses external force constraints, it is easy to rebound and deform. The pressure applied by the anti-deformation spring 25 can maintain the shape of the winding in a short time, ensuring the shape stability of the winding during the removal process, thereby ensuring the quality of the stator and the accuracy of subsequent motor assembly.

[0056] Embodiment 2: Figures 8 to 10 As shown, on the basis of Example 1, a lead clamping assembly 3 for preventing the lead from being squeezed by the arc-shaped pressing block is arranged above the round convex clamping seat 14, and the lead clamping assembly 3 includes two bosses 31, and the bosses 31 are symmetrically fixedly connected to the top of the round convex clamping seat 14, and the top of the round convex clamping seat 14 is fixedly connected with a convex strip 32, and the outer surface of the convex strip 32 is symmetrically slidably connected with a clamping block 33, and a clamping groove 34 is provided on the side close to the two clamping blocks 33, and a reset spring 35 is fixedly connected between each clamping block 33 and the boss 31.

[0057] It should be noted that the lead clamping assembly 3 is symmetrically arranged with the middle of the protruding strip 32 as the center line, and the two clamping blocks 33 are both arranged on the side closest to the stator winding, and the edges of the clamping groove 34 are transitionally rounded, and the top of the clamping block 33 is trapezoidal in shape.

[0058] Specifically, while placing the stator on the base, the operator holds the lead wire and presses the lead wire against the surface of the block 33. Since the top of the block 33 is a trapezoidal shape, this special shape provides a guiding effect for the lead wire, so that the lead wire can be smoothly guided to the middle of the two blocks 33.

[0059] The operator then pulls the lead wire downward, and under the guidance of the trapezoidal slope on the top of the block 33 and the rounded edge of the slot 34, the lead wire generates a resistance force on the block 33. At this time, since the reset spring 35 is fixedly connected between the block 33 and the boss 31, the resistance of the lead wire will cause the block 33 that is resisted by the lead wire to shrink through the elasticity of the reset spring 35, thereby sliding on the surface of the convex strip 32 toward the side away from the center, making room for the lead wire to enter and exit, so that the lead wire can smoothly reach the position of the slot 34.

[0060] When the lead wire reaches the position of the card slot 34, the operator releases the hand. Under the action of the loss of external force, the return spring 35 extends by its own elasticity and drives the clamping block 33 to slide towards the middle. At this time, the clamping block 33 and the card slot 34 cooperate with each other to limit the lead wire in the middle, thus effectively preventing the driving cylinder 12 from accidentally pressing the lead wire during subsequent operations.

[0061] After the pressing is completed, the operator holds the lead wire again and pulls it upward. Under the action of the rounded corner of the card slot 34, the lead wire exerts an upward pulling force on the clamping block 33, causing the clamping block 33 to compress the return spring 35, thereby creating space for the removal of the lead wire. At this time, the lead wire can be smoothly removed, and at the same time, the return spring 35 elastically extends and drives the clamping block 33 to reset, preparing for the next operation.

[0062] It should be noted that the lead wire clamping assembly 3 does not require the operator to hold the lead wire all the time. From the perspective of operation convenience, the operator does not need to maintain the posture of holding the lead wire for a long time, reducing operation fatigue. Secondly, from the perspective of operation accuracy, the operator can focus more attention on the assembly operation of the stator and the base, without being distracted by the action of holding the lead wire, and can perform operations such as placing, adjusting, and pressing the stator more precisely. Moreover, from the perspective of safety, the time for the operator's hand to be exposed near the pressing equipment is reduced. In some complex assembly environments, there is a certain safety risk for the operator's hand to be close to the pressing equipment, and this design reduces the possibility of such risks occurring.

[0063] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
