Description

Technical Field

[0001] This invention relates to the field of iron core winding, and particularly to an automatic winding device and method. Background Technology

[0002] Before coil 1a is embedded in iron core 2a, it is in a loose and scattered state. Please refer to the appendix. Figure 1 The coil consists of a coil insert and a loop. The width H1 of the coil insert is greater than the slot width h1 of the iron core slot 3a, and the height H2 of the coil insert is greater than the depth h2 of the iron core slot 3a. If a loose, frizzy coil is directly placed into the iron core slot 3a, the coil insert will pop out of the slot opening, making it impossible to lay the coil. Therefore, in the process of manually embedding the coil insert into the iron core slot 3a, it needs to be embedded in layers. After embedding one layer, the embedded part is compacted, then another layer is embedded, and so on. In this way, the entire coil insert is embedded into the iron core slot 3a. Obviously, the manual layered embedding method is labor-intensive, difficult to operate, and cannot guarantee the consistency of the winding quality.

[0003] Therefore, how to reduce the labor intensity and difficulty of wire embedding, and ensure the consistency of wire embedding quality, is a key issue that urgently needs to be addressed by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to reduce the labor intensity of wire embedding, reduce the difficulty of wire embedding, and ensure the consistency of wire embedding quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic wire-embedding device, comprising: The frame has a feeding station, a wire-embedding station, and a separation station; A shaping fixture has multiple shaping teeth arranged in a ring, and a shaping groove is formed between two adjacent shaping teeth. The depth of the shaping groove is greater than the height of the fluffy coil, and the width of the shaping groove is less than the width of the iron core groove used to embed the coil. A wire-insertion fixture, located at the wire-insertion station and mounted on the frame, is used to compact the fluffy coil in the shaping groove. It has a first drive member and a pressure plate. The first drive member is used to drive the pressure plate to move so that the pressure plate applies pressure to the fluffy coil. The pressure plate has a pressing part that corresponds to the position of the shaping groove and is adapted in shape. A lifting fixture, mounted on the shaping fixture, is used to lift the compressed coil so that the compressed coil moves along the shaping teeth; The pick-and-place fixture, located at the separation station and installed on the frame, is used to pick up the clamping coil after it has been pressed on the shaping fixture, and to place the clamping coil in the iron core slot. A moving device, connected to the shaping fixture, is used to move the shaping fixture to the feeding station, the embedding station, or the separating station.

[0006] Preferably, in the above-described automatic winding device, the lifting fixture includes a wire-removing plate and a second driving component. The de-threading plate has shaped toothed holes, and the de-threading plate is fitted onto the shaped teeth through the shaped toothed holes, forming de-threading teeth between two adjacent shaped toothed holes. The second driving member is used to drive the decoupling plate to move, so that the decoupling teeth push the compressed coil to move along the shaping teeth, thereby separating the compressed coil from the shaping teeth.

[0007] Preferably, in the above-described automatic winding device, the thread-removing teeth protrude beyond the plane of the thread-removing plate, and the portion of the thread-removing teeth protruding beyond the plane of the thread-removing plate can extend into the shaping groove. The width of the de-coring tooth is smaller than the width of the shaping groove.

[0008] Preferably, in the above-mentioned automatic winding device, the pick-and-place fixture includes: The winding substrate and winding teeth disposed on the winding substrate, wherein a plurality of winding teeth are arranged at intervals around the central axis of the winding substrate, and a winding groove is formed between two adjacent winding teeth. The number of winding grooves is equal to the number of iron core grooves. The wire release plate can push the clamping coil into the winding groove under the drive of the second driving member. A pusher plate, wherein multiple pusher plates are spaced apart around the central axis of the pusher plate, each pusher tooth is located in a wire insert groove, and a wire insert tooth hole is formed between two adjacent pusher teeth to avoid the wire insert tooth; The third driving component can drive the winding fixture to dock with the iron core, and the fourth driving component drives the push plate to move down so as to push the coil in the winding slot into the iron core slot.

[0009] Preferably, in the above-mentioned automatic winding device, the third driving component is a cylinder, the fourth driving component is an electric cylinder, the frame includes a fixed plate, the third driving component and the fourth driving component are disposed on the fixed plate, the piston of the cylinder is connected to the winding base plate, and the piston of the electric cylinder is connected to the inner ring of the push plate.

[0010] Preferably, in the above-mentioned automatic winding device, the pick-and-place fixture further includes an anti-detachment component. The anti-detachment assembly includes an anti-detachment plate and a telescopic cylinder. The anti-detachment plate is connected to the lower part of the winding base plate. The anti-detachment plate has through holes to avoid the winding teeth and the clamping coil. The telescopic cylinder is arranged radially on the lower surface of the anti-detachment plate along the winding base plate. When the piston of the telescopic cylinder is in the extended state, it engages with the winding teeth to support the clamping coil in the winding groove. When the piston of the telescopic cylinder is in the retracted state, it avoids the movement of the clamping coil.

[0011] Preferably, in the above-mentioned automatic wire embedding device, the frame further includes a guide plate, the guide plate is located between the fixed plate and the wire embedding substrate, the guide plate is connected to the fixed plate, and a guide post is connected to the wire embedding substrate, the guide post passing through the guide hole of the guide plate.

[0012] Preferably, in the above-described automatic winding device, the moving device is at least one of a conveyor belt and a guide rail assembly.

[0013] An automatic wire embedding method, comprising: Move the shaping fixture to the loading station and fit a loose coil onto the shaping fixture; Move the shaping fixture to the winding station, and use the winding fixture to press the loose coil of the shaping fixture to obtain a pressed coil; Move the shaping fixture to the separation station, and separate the clamping coil from the shaping fixture by using the lifting fixture; The clamping coil is picked up by the pick-and-place tool and placed into the core slot of the iron core.

[0014] Preferably, in the above-described automatic winding method, the specific steps of picking up the clamping coil using a pick-and-place fixture and placing the clamping coil into the core slot of the iron core are as follows: The clamping coil on the lifting fixture is picked up using the pick-and-place tool; Move the shaping fixture to the loading station, and the iron core moves from the iron core loading / unloading station to the separation station; The clamping coil is placed in the core slot of the iron core by means of the pick-and-place tool; Move the iron core to the iron core loading and unloading station.

[0015] As can be seen from the above technical solution, the automatic winding device of the present invention, through the cooperation of the shaping fixture and the winding fixture, compresses the loose coil into a compressed coil with a width smaller than the width of the iron core groove. The shaped compressed coil can be embedded into the iron core groove in one go. Compared with the existing technology of layered embedding into the iron core groove, the one-time embedding solution in this embodiment significantly reduces the labor intensity and difficulty of winding. At the same time, since the coil is shaped and compacted as a whole by the pressure plate, the compaction degree of each coil embedding part is basically the same, thereby ensuring the consistency of winding quality. The shaping fixture, winding fixture, separation fixture and moving device work together to realize the automatic shaping, automatic lifting and automatic picking and placing of loose coil, reduce manual intervention, improve the degree of automation, reduce the labor intensity of manual labor, and at the same time ensure the consistency of winding quality.

Detailed Implementation

[0020] In view of this, the core of the present invention is to design a shaping tool to compact the loose coil into a compressed coil, thereby facilitating its one-time overall embedding into the iron core.

[0021] Another core aspect of this invention lies in designing an automatic wire-embedding device with the aforementioned shaping fixture.

[0022] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to Figures 2-10 .

[0024] The present invention discloses an automatic wire embedding device, including a frame 300, a shaping fixture, a wire embedding fixture, a lifting fixture, a pick-and-place fixture, and a moving device.

[0025] Among them, the frame 300 has a feeding station A, a wire embedding station B and a separation station C; The shaping fixture has multiple shaping teeth 102 arranged in a ring. A shaping groove 103 is formed between two adjacent shaping teeth 102. The depth of the shaping groove 103 is greater than the height of the fluffy coil, and the width of the shaping groove 103 is less than the width of the iron core groove used to embed the coil. The winding fixture, located at the winding station and mounted on the frame 300, is used to compact the fluffy coil in the shaping groove 103. It has a first drive member and a pressure plate. The first drive member is used to drive the pressure plate to move so that the pressure plate applies pressure to the fluffy coil. The pressure plate has a pressing part 202 that corresponds to the position of the shaping groove 103 and is adapted in shape. The lifting fixture is set on the shaping fixture and is used to lift the coil after it is pressed so that the coil after it is pressed can move along the shaping teeth 102. The pick-and-place fixture is located at the separation station and installed on the frame 300. It is used to pick up the clamping coil after it has been pressed on the molding fixture and to place the clamping coil in the iron core slot. A moving device, connected to the shaping fixture, is used to move the shaping fixture to the feeding station A, the stitching station B, or the separation station C.

[0026] The frame 300 includes a loading station A, a winding station B, a separating station C, and a core loading / unloading station D. At the loading station A, the coil is placed onto the shaping fixture. The winding fixture is located at the winding station B, the picking / unloading fixture is located at the separating station C, and the moving device is mounted on the frame 300.

[0027] The moving device drives the shaping fixture to move from the loading station A to the winding station B. The winding fixture presses the loose coil in the shaping fixture and the coil in the shaping groove 103. The moving device drives the shaping fixture to move to the separation station C. The lifting fixture pushes out the pressed coil in the shaping fixture. The pick-and-place fixture picks up the pushed-out coil and puts it into the core groove of the iron core.

[0028] After the pick-and-place fixture picks up the coil, the moving device drives the shaping fixture back to the loading station A.

[0029] The core loading and unloading device drives the core 500 from the core loading and unloading station D to the separation station C. At the separation station C, the tooling inserts the clamping coil 100 into the core slot of the core 500. Afterwards, the core loading and unloading device drives the core 500 back to the core loading and unloading station D, and the core 500 with the coil inserted is unloaded.

[0030] The automatic winding device in this invention uses a shaping fixture in conjunction with a winding fixture to compress a loose coil into a compressed coil with a width smaller than the width of the core slot. The shaped compressed coil 100 can be embedded into the core slot in one go. Compared with the existing technology of layered embedding into the core slot, the one-time embedding method in this embodiment significantly reduces the labor intensity and difficulty of winding. At the same time, since the coil is shaped and compacted as a whole by the pressure plate, the compaction degree of each coil embedding part is basically the same, thereby ensuring the consistency of winding quality.

[0031] The automatic winding device disclosed in this solution can automatically shape, lift, and pick up / place loose coils, reducing manual intervention, improving the degree of automation, reducing the intensity of manual labor, and ensuring the consistency of winding quality.

[0032] The shaping fixture includes a shaping substrate 101 and shaping teeth 102. The shaping substrate 101 is connected to a moving device. The shaping teeth 102 are disposed on the shaping substrate 101, and a shaping groove 103 is formed between two adjacent shaping teeth 102. Optionally, the number of shaping grooves 103 is equal to the number of core grooves of the iron core 500, and they correspond one-to-one. Figure 3 As shown, multiple shaping teeth 102 are arranged at intervals around the central axis of the shaping substrate 101 and form a ring.

[0033] In this design, the depth of the shaping groove 103 is greater than the height of the coil in its fluffy state, and the width of the shaping groove 103 is less than the width of the core groove. For example... Figure 1 As shown, the coil includes a coil insert and a coil loop. When the coil inserts in the fluffy state are placed into the shaping groove 103 of the shaping fixture, the coil inserts will be completely located within the shaping groove 103 and will not pop out of the shaping groove 103.

[0034] The winding fixture is mounted on the frame 300 and located above the shaping fixture. It includes a first drive member and a pressure plate. The first drive member is used to drive the pressure plate to move so that the pressure plate applies pressure to the fluffed coil. The pressure plate has a pressing part 202 that corresponds to the position of the shaping groove 103 and is adapted in shape.

[0035] Multiple pressing parts 202 are arranged at intervals around the central axis of the pressure plate 201, and a clearance hole 203 is formed between two adjacent pressing parts 202 to avoid the shaping teeth 102. As the pressure plate moves, the pressing parts 202 enter the shaping groove 103 to compress the coil insert in the shaping groove 103.

[0036] Optionally, the outer diameter of the pressure plate 201 is larger than the outer diameter of the coil in a fluffy state, and while the pressure part 202 is pressing the coil insert, the pressure plate 201 will press the coil loop.

[0037] Since the coil insert is completely located within the shaping groove 103, and the outer diameter of the pressure plate 201 is larger than the outer diameter of the coil, the coil will be compacted in the height direction when the pressure plate squeezes the coil. At the same time, since the width of the shaping groove 103 is smaller than the width of the iron core groove, the width of the coil insert after being shaped and compacted is smaller than the width of the iron core groove, so that the shaped and compacted coil 100 can be embedded into the iron core groove of the iron core in one go.

[0038] The pressure plate 201 is an annular plate, including an inner ring and an outer ring. The pressure plate 201 is connected to the frame 300 through a first driving member. The first driving member is connected to the inner ring of the pressure plate 201, driving the pressure plate to move away from or towards the shaping fixture, thus realizing the automated shaping of the fluffy coil.

[0039] The lifting fixture is mounted on the shaping fixture. The lifting fixture includes a wire-removing plate 104 and a second driving member. The wire-removing plate has shaping tooth holes 106. The wire-removing plate is sleeved on the shaping teeth 102 through the shaping tooth holes 106. A wire-removing tooth 105 is formed between two adjacent shaping tooth holes 106. The wire-removing tooth 105 is used to support the coil insert in the shaping groove 103. The second driving member is used to drive the wire-removing plate 104 to move, so that the wire-removing tooth 105 pushes the compressed coil to move along the shaping teeth 102, thereby realizing the separation of the compressed coil from the shaping teeth 102.

[0040] The lifting fixture is located above the shaping fixture. The wire stripping plate 104 is connected to the frame 300 through the second drive component. The movement of the wire stripping plate causes the wire stripping teeth 105 to push out the coil insert in the shaping groove 103, thereby facilitating the embedding of the clamping coil 100 into the iron core groove.

[0041] The second driving member drives the wire-removing plate 104 to reciprocate in a direction perpendicular to the molding substrate 101. The second driving member is connected to the inner ring of the wire-removing plate 104 via the first connecting member. Optionally, the second driving member is a telescopic cylinder. When the telescopic rod of the second driving member is in the retracted state, the wire-removing teeth 105 are located in the molding groove 103 to support the coil insert in the molding groove 103; when the telescopic rod of the second driving member is in the extended state, the wire-removing teeth 105 push the molded clamped coil 100 out of the molding groove 103. The second driving member enables the automatic separation of the clamped coil 100 from the molding groove 103.

[0042] The de-coring teeth 105 of the de-coring plate 104 protrude from the plane of the de-coring plate 104. The part of the de-coring teeth 105 protruding from the plane of the de-coring plate 104 can extend into the shaping groove 103. The part of the de-coring teeth 105 protruding from the de-coring plate 104 can support the clamping coil, and the de-coring teeth 105 can limit the shaping tooling.

[0043] Optionally, the tooth width of the de-threading tooth 105 is smaller than the groove width of the shaping groove 103, which reduces the assembly difficulty of the de-threading plate 104 and the shaping fixture, and at the same time reduces the damage to the shaping fixture caused by the movement of the de-threading plate 104.

[0044] The hardness of the part of the de-coring tooth 105 that protrudes from the plane of the de-coring plate 104 is lower than that of the part of the plane of the de-coring plate 104. The part of the de-coring tooth 105 with higher hardness plays a supporting role, which is conducive to the shaping and ejection of the coil 100. The part of the de-coring tooth 105 with lower hardness contacts the shaping tooth 102, so as to avoid scratches on the shaping tooth 102 and damage to the coil.

[0045] Optionally, the hard tooth portion and the soft tooth portion of the de-threading tooth 105 are separate structures, and the soft tooth portion is detachably connected to the de-threading plate 104.

[0046] The pick-and-place fixture includes a wire-insertion substrate, wire-insertion teeth 404, and a wire pusher plate.

[0047] The wire-insertion substrate is connected to the frame 300. The wire-insertion substrate has the same shape as the iron core. Multiple wire-insertion teeth 404 are disposed on the lower surface of the wire-insertion substrate. The multiple wire-insertion teeth 404 are arranged at intervals around the central axis of the wire-insertion substrate. Two adjacent wire-insertion teeth 404 form a wire-insertion groove. Optionally, the number of wire-insertion grooves is equal to the number of iron core grooves. The wire-insertion substrate and the wire-insertion teeth 404 conform to the iron core 500.

[0048] The push plate 403 has push teeth, and multiple push teeth are spaced apart around the central axis of the push plate 403. The number of push teeth and the number of inserting slots are equal and correspond one-to-one. An inserting tooth hole is formed between two adjacent push teeth to avoid the inserting tooth 404. The push plate 403 is fitted onto the inserting tooth 404 through the inserting tooth hole.

[0049] The third driving component is used to drive the winding substrate to move up and down. When the shaping fixture is in the separation station, the shaping fixture is located directly below the pick-and-place fixture. The third driving component drives the winding substrate to move down and dock with the shaping fixture. The wire removal plate in the shaping fixture pushes the clamping coil 100 in the shaping groove 103 into the winding groove.

[0050] When the iron core 500 is directly below the pick-and-place fixture, the third drive unit drives the winding substrate to move down and align with the iron core 500. Then, the fourth drive unit drives the push plate to move down, pushing the clamping coil 100 in the winding slot into the iron core slot. The arrangement of the second, third, and fourth drive units enables the automatic transfer of the clamping coil 100 from the shaping fixture to the winding fixture and from the winding fixture to the iron core 500.

[0051] The winding teeth 404 and winding substrate, as well as the shaping teeth 102 and shaping substrate 101, all conform to the shape of the iron core 500. Therefore, the number of winding slots is equal to the number of shaping slots 103. To facilitate the wire release plate in pushing the clamping coil 100 in the shaping slot 103 into the winding slot, this invention limits the width of the winding slot to be greater than the width of the shaping slot 103, but smaller than the width of the iron core slot. The width of the winding slot refers to the circumferential dimension of the winding slot on the winding substrate.

[0052] In a specific embodiment of the present invention, the third driving component is preferably a pneumatic cylinder, and the fourth driving component is preferably an electric cylinder. The frame 300 includes a fixing plate 301, on which both the pneumatic and electric cylinders are mounted. The piston of the pneumatic cylinder is connected to the wire-inserting substrate. The piston of the electric cylinder is connected to the inner ring of the wire-pushing plate 403 via a second connecting member. The second connecting member is arranged radially along the wire-pushing plate 403.

[0053] The winding process of the winding fixture into the iron core 500 is as follows: the cylinder and the electric cylinder are started. The piston of the cylinder pushes the winding fixture down, and the piston of the electric cylinder extends accordingly. When the loading and unloading fixture is connected with the iron core 500, the piston of the cylinder stops extending, and the piston of the electric cylinder continues to extend. The piston of the electric cylinder pushes the push plate 403 down, and the push plate pushes the clamping coil 100 in the winding groove into the iron core 500.

[0054] The structure of the pusher plate is similar to that of the release plate. As described above, the pusher plate includes a pusher plate 403 and pusher teeth disposed on the pusher plate 403. A wire-inserting tooth hole is formed between two adjacent pusher teeth.

[0055] The specific structure of the pusher teeth and the insert teeth holes is as follows: The push plate 403 has multiple first thread-inserting holes, which are spaced apart around the central axis of the push plate 403. A first push tooth is formed between two adjacent first thread-inserting holes. The first push teeth are formed simultaneously when the first thread-inserting holes are machined on the push plate 403. Each first push tooth has a second push tooth. The two ends of the second push tooth extend radially out of the thread-inserting groove along the thread-inserting substrate. The two ends of the second push tooth are locked to the push plate 403 by locking members. The first and second push teeth together form a push tooth structure.

[0056] The first and second push teeth are positioned vertically within the winding groove. The width of the second push tooth is wider than that of the first push tooth, so the side of the second push tooth contacts the winding tooth 404, while the side of the first push tooth does not contact the winding tooth 404. The second push tooth that contacts the winding tooth 404 is a soft tooth, so it will not scratch the winding tooth 404 during the up-and-down movement of the push plate, thus avoiding scratches on the winding tooth 404 and damage to the coil. The first push tooth that does not contact the winding tooth 404 is a hard tooth, providing support and facilitating the ejection of the clamping coil 100 from the winding groove.

[0057] A second insert tooth hole is formed between two adjacent second push teeth. The second insert tooth hole and the first insert tooth hole together form the insert tooth hole mentioned above, used to avoid the insert tooth 404. The second push teeth are wider than the first push teeth, so the fit between the second insert tooth hole and the insert tooth 404 is tighter than the fit between the first insert tooth hole and the insert tooth 404. There is no direct connection between the second push teeth; each second push tooth is locked onto the push plate 403. The position of each second push tooth is adjustable, so the size of the second insert tooth hole is adjustable to facilitate matching with the insert tooth 404, thereby reducing the machining and assembly difficulty of the second push teeth.

[0058] In this invention, the opening of the winding groove faces downwards. To prevent the clamping coil 100 inside the winding groove from coming out, a specific embodiment of this invention includes an anti-detachment component. The anti-detachment component includes an anti-detachment plate 401 and a telescopic cylinder 402. The anti-detachment plate 401 is connected to the lower part of the winding substrate and has through holes for the winding teeth 404 and the clamping coil 100 to pass through. The telescopic cylinder 402 is disposed on the lower surface of the anti-detachment plate 401 and is arranged radially along the winding substrate. When the piston of the telescopic cylinder 402 is in the extended state, the piston of the telescopic cylinder 402 contacts the side of the winding teeth 404 and provides support for the clamping coil 100 above. When the piston of the telescopic cylinder 402 is in the retracted state, it avoids the movement of the clamping coil 100, ensuring that the clamping coil 100 enters the winding fixture from the shaping fixture or enters the iron core 500 from the winding fixture. The telescopic cylinder 402 can specifically be a pneumatic cylinder, and there are multiple pneumatic cylinders spaced apart around the central axis of the wire-insertion substrate.

[0059] The frame 300 includes a fixed plate 301 and a guide plate 302, which is disposed between the fixed plate 301 and the wire-inserting substrate and is connected to the fixed plate 301. A guide post 303 is connected to the wire-inserting substrate and passes through a guide hole in the guide plate 302. When the third driving component drives the wire-inserting fixture to move up and down, the cooperation between the guide post 303 and the guide hole ensures the movement accuracy of the wire-inserting fixture.

[0060] In summary, the operation process of the automatic winding device is as follows: At the loading station A, the coil in a fluffy state is placed into the shaping groove 103 of the shaping fixture; at the iron core loading and unloading station D, the iron core 500 to be wound is placed; the moving device drives the shaping fixture to move to the winding station B, the first driving component drives the pressure plate to move down, and each pressing part 202 of the pressure plate enters the corresponding shaping groove 103 to squeeze the coil, forming a pressed coil 100; the first driving component drives the pressure plate to reset; the moving device drives the shaping fixture to move to the separation station C, the third driving component...

[0061] This solution also discloses an automatic wire embedding method, including: moving the shaping fixture to the feeding station and attaching a loose coil to the shaping fixture; Move the shaping fixture to the winding station, and use the winding fixture to press the loose coil of the shaping fixture to obtain a pressed coil; Move the shaping fixture to the separation station, and use the lifting fixture to separate the clamping coil from the shaping fixture; The clamping coil is picked up using a pick-and-place tool and placed into the core slot of the iron core.

[0062] The automatic wire embedding method disclosed in this solution is applicable to the automatic wire embedding device described in the above solution. Since the automatic wire embedding device has the above-mentioned technical effects, the automatic wire embedding method applicable to the automatic wire embedding device also has the same technical effects, and will not be described again here.

[0063] In some embodiments, the clamping coil is picked up by a pick-and-place fixture and placed into the core slot of the iron core. The pick-up and drop fixture picks up the clamping coil on the lifting fixture. The pick-up fixture moves the clamping coil upward and fixes it on the pick-up fixture through the anti-detachment component to prevent the clamping coil from falling. Move the shaping fixture to the loading station and continue the subsequent loading and wire embedding processes. After the shaping fixture leaves the separation station, the iron core moves from the iron core loading and unloading station to the separation station. The loading and unloading fixture places the clamping coil into the core slot of the iron core. After placement, the iron core is moved to the loading and unloading station.

[0064] The driving structure that drives the iron core to move at the iron core loading / unloading station and the separation station, and the moving device that drives the shaping fixture to move are two independent structures that work independently and do not affect each other.

[0065] In the description of this invention, it should be noted that the terms "upper", "lower", "bottom", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0066] Furthermore, the use of terms such as "horizontal," "vertical," and "perpendicular" does not imply that the component must be absolutely horizontal or vertical, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0067] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0068] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
