Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and more specifically, to oiling devices and piston dust cover oiling equipment. Background Technology

[0002] Automotive parts such as piston dust covers that require a sealed sliding fit need to be lubricated on specific areas such as the end faces during the manufacturing process to ensure sealing and smooth movement.

[0003] Currently, manual oiling is the most common method. This method is not only inefficient and difficult to adapt to the needs of mass production, but also results in unstable oiling quality, which can easily lead to missed areas or uneven oiling, affecting the assembly quality and service life of the product.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] This application provides an oiling device and a piston dust cover oiling equipment, which can realize automated oiling, improve oiling efficiency, ensure oiling uniformity and consistency, and improve product quality.

[0006] According to one aspect of this application, an oiling device is provided, comprising: a support; a gripper mechanism mounted on a first moving mechanism, the first moving mechanism being configured with a travel toward and away from the support, the gripper mechanism being configured with a clamping state and a releasing state; and a pressure head assembly mounted on a second moving mechanism, the second moving mechanism being configured with a travel toward and away from the support; wherein the support, the gripper of the gripper mechanism, and the pressure head assembly are arranged sequentially and do not interfere with each other, and the support and / or the pressure head assembly are configured with lubricating oil supply channels.

[0007] The bearing seat, gripper mechanism, and pressure head assembly are arranged sequentially and do not interfere with each other. This allows the gripper mechanism, bearing seat, and pressure head assembly to respectively clamp / support different parts of the workpiece to be oiled during the oiling process. Furthermore, the lubricating oil supply channels configured in the bearing seat and / or pressure head assembly apply oil to the parts of the workpiece that contact the bearing seat and / or pressure head assembly. The oiling device of this application, through the cooperation of the bearing seat, gripper mechanism, and first moving mechanism, as well as the pressure head assembly and second moving mechanism, achieves automatic clamping, positioning, and oiling of the workpiece, improving oiling efficiency, ensuring oiling uniformity and consistency, and enhancing product quality.

[0008] It should be noted that the oiling device of this application is not limited to applying lubricating oil to the workpiece, but may also be other protective media.

[0009] In some embodiments, the gripper mechanism includes a pair of openable grippers that are close to each other in the clamping state and far apart from each other in the releasing state; wherein, when the pair of grippers are close to each other, the pair of grippers limit a clamping space that adapts to the outer contour of the clamped portion of the workpiece.

[0010] The clamping space of a pair of jaws is adapted to the outer contour of the clamped part of the workpiece, ensuring stable clamping without interfering with the oiling area.

[0011] In some embodiments, the grippers are formed as sheet structures, wherein the thickness of each gripper is in the range of 0.5 mm to 1.5 mm.

[0012] The grippers adopt a thin sheet structure, which can reduce the contact area with the workpiece, prevent the grippers from getting contaminated with lubricating oil and affecting the workpiece or the clamping, and at the same time provide space for the oiling area to ensure that the oiling is sufficient.

[0013] In some embodiments, the pressure head assembly includes: a fixed base connected to the second moving mechanism; and an oiling head detachably connected to the fixed base, wherein the oiling head has a lubricating oil channel, and the end of the oiling head near the support base has a first lubricating oil outlet communicating with the lubricating oil channel.

[0014] The pressure head assembly adopts a split design, connected to the second moving mechanism via a fixed base. Lubricating oil is delivered through the lubrication channel of the oiling head and coated through the first lubrication outlet. Furthermore, the oiling head is detachably connected to the fixed base for easy replacement and cleaning, improving maintenance convenience.

[0015] In some embodiments, the oiling head includes an annular body and a flange extending from a first end of the annular body away from the annular body; the flange extends into and is connected to the fixing seat; the inner cavity of the flange is connected to a lubricating oil channel disposed in the annular body, and the first lubricating oil outlets are evenly distributed at intervals at a second end of the annular body opposite to the first end.

[0016] The oiling head adopts an integrated structure of annular body and flange, and uses the flange to connect to the fixed seat. The uniformly distributed first lubricating oil outlet at the second end of the annular body achieves uniform circumferential oiling of the workpiece.

[0017] In some embodiments, the lubricating oil passage disposed in the annular body includes: a radially extending passage disposed in a first end of the annular body, and the first end of the annular body is formed as a sealed end; and an axially extending passage disposed in the annular portion of the annular body; wherein the radially extending passage communicates with the inner cavity of the flange, the axially extending passage communicates with the radially extending passage and the first lubricating oil outlet, and the radially extending passage and the outlet of the axially extending passage located on the outer wall of the annular body are blocked.

[0018] The lubricating oil is guided to the second end of the annular body by the cooperation of the radial extension channel and the axial extension channel, and a sealed delivery is achieved to prevent the lubricating oil from leaking out.

[0019] In some embodiments, the oil inlet of the lubricating oil channel is disposed on the fixed base, and the fixed base is provided with a channel connecting the oil inlet and the inner cavity of the flange.

[0020] The oil inlet nozzle can be configured as a quick connector for easy connection with an external oil supply system.

[0021] In some embodiments, the flange is screwed to the mounting base or connected by fasteners. This ensures a secure connection and facilitates disassembly and maintenance.

[0022] In some embodiments, the pressure head assembly includes: a mounting base connected to the drive output of the second moving mechanism; and a floating mechanism connected between the mounting base and the fixed base.

[0023] The floating mechanism allows the oiling head to self-adjust and finely adjust when it comes into contact with the workpiece, avoiding workpiece deformation caused by rigid pressing.

[0024] In some embodiments, the floating mechanism includes: a fastener, one end of which passes through the mounting base and is hooked onto the mounting base, and the other end of which is fixedly connected to the fixed base; and an elastic element that is elastically and telescopically connected between the mounting base and the fixed base.

[0025] The fastener clearance extends through the mounting base to allow floating and provide restraint, ensuring smooth floating only along the direction of the fastener's extension; the elastic element can compress and absorb impact, protecting the workpiece and the oiling head. This combination of fasteners and elastic elements utilizes a simple and reliable structure to allow the oiling head to contact the workpiece in a cushioned and flexible manner, avoiding damage to the workpiece.

[0026] In some embodiments, the fastener is a screw, and / or the elastic element is a spring and is sleeved on the fastener.

[0027] As a fastener, the screw serves both a connecting and guiding function. The spring is sleeved on the screw, resulting in a compact structure that floats smoothly and is easy to assemble and adjust the preload.

[0028] In some embodiments, the support includes: a base having a lubricating oil inlet; and a porous material detachably disposed in the base, wherein the surface of the porous material forms a bearing surface and second lubricating oil outlets are uniformly distributed in the porous material.

[0029] By using porous materials, lubricating oil can penetrate into the bearing surface through a second lubricating oil outlet that is evenly spaced, thereby achieving uniform immersion oiling of the parts of the workpiece that are in contact with the bearing surface.

[0030] In some embodiments, the first moving mechanism includes: a horizontal moving mechanism having a horizontal moving stroke away from and towards the support; a first lifting mechanism connected to a drive output of the horizontal moving mechanism, and the gripper mechanism connected to a drive output of the first lifting mechanism, the first lifting mechanism having a first lifting stroke away from and towards the support; the second moving mechanism includes: a second lifting mechanism, the pressure head assembly connected to a drive output of the second lifting mechanism, the second lifting mechanism having a second lifting stroke away from and towards the support.

[0031] The first moving mechanism achieves a combined horizontal and vertical motion through a horizontal moving mechanism and a first lifting mechanism, enabling precise transport of the workpiece from the material handling station to the oiling station; the second moving mechanism includes a second lifting mechanism, which can control the downward pressing and oiling and the lifting and releasing of the pressure head assembly.

[0032] In some embodiments, the oiling device further includes a workpiece placement fixture, the horizontal moving mechanism having a first working position away from the support and close to the workpiece placement fixture, and a second working position away from the workpiece placement fixture and close to the support.

[0033] The workpiece placement fixture serves as the material handling station, which is separate from the oiling station on the support, enabling continuous operation and improving production efficiency.

[0034] In some embodiments, both the first moving mechanism and the second moving mechanism are driven by cylinders, which are fast-responding, simple in structure, and easy to maintain, making them suitable for industrial automation scenarios.

[0035] According to another aspect of this application, a piston dust cover oiling device is provided, the piston dust cover oiling device being configured with an oiling apparatus as described in any of the above embodiments, wherein the piston dust cover is provided with a first end and a second end to be oiled, the gripper mechanism is configured to grip the gripped portion between the first end and the second end of the piston dust cover, the support seat is configured to support the piston dust cover and oil the first end of the piston dust cover, and the pressure head assembly is configured to contact the piston dust cover and oil the second end of the piston dust cover.

[0036] The piston dust cover is clamped in the middle by grippers, while the bearing seat applies oil to the lower first end of the piston dust cover, and the pressure head assembly applies oil to the upper second end of the piston dust cover. This achieves simultaneous automated oiling at both ends, replacing manual operation and improving oiling quality and efficiency. The piston dust cover is a core rubber component in braking systems such as hydraulic disc brakes. During assembly, the piston dust cover oiling equipment of this application evenly applies lubricating oil to both ends of the piston dust cover, ensuring its sealing performance and smooth operation.

[0044] Figure 1 The structure of the oiling device is illustrated, with reference to... Figure 1As shown, the oiling device provided in this application embodiment may include: a support 100; a gripper mechanism 200 mounted on a first moving mechanism 300, the first moving mechanism 300 having a moving stroke toward and away from the support 100, and the gripper mechanism 200 having a clamping state and a releasing state; and a pressure head assembly 400 mounted on a second moving mechanism 500, the second moving mechanism 500 having a moving stroke toward and away from the support 100; wherein the support 100, the gripper 220 of the gripper mechanism 200, and the pressure head assembly 400 can be arranged sequentially and do not interfere with each other, and the support 100 and / or the pressure head assembly 400 are provided with a lubricating oil supply channel.

[0045] The support 100 is used to support the workpiece 800 to be oiled. The gripper mechanism 200 grips and releases the workpiece 800 through clamping and releasing states. In conjunction with the movement of the first moving mechanism 300, the workpiece 800 can be transported to the support 100 for oiling or removed from the support 100. The pressure head assembly 400 is used to contact (or slightly press as needed) the workpiece 800 placed on the support 100, keeping the workpiece 800 stable and thus facilitating smooth oiling. The bearing seat 100, the gripper 220 of the gripper mechanism 200, and the pressure head assembly 400 are arranged sequentially and do not interfere with each other. This allows the gripper mechanism 200, the bearing seat 100, and the pressure head assembly 400 to clamp / support different parts of the workpiece 800 in the oiled state. For example, the gripper mechanism 200 uses the gripper 220 to clamp the side of the workpiece 800, and the bearing seat 100 and the pressure head assembly 400 are aligned to clamp the two end faces of the workpiece 800. The lubricating oil supply channels configured in the bearing seat 100 and / or the pressure head assembly 400 are used to apply oil to the parts of the workpiece 800 that are in contact with the bearing seat 100 and / or the pressure head assembly 400.

[0046] The oiling device of this application, through the cooperation of the support seat 100, the gripper mechanism 200 and the first moving mechanism 300, and the pressure head assembly 400 and the second moving mechanism 500, realizes the automatic clamping, positioning and oiling of the workpiece 800 to be oiled, improves oiling efficiency, ensures oiling uniformity and consistency, and improves product quality.

[0047] It should be noted that the oiling device of this application is not limited to applying lubricating oil to the workpiece 800, but may also be other protective media.

[0048] Figure 2 The diagram illustrates the structure of a pair of grippers. Figure 3 The diagram illustrates the structure of a pair of grippers holding workpiece 800. Figure 4 This diagram illustrates the structure where a pair of grippers releases the workpiece. (Combined) Figures 1 to 4As shown, in some embodiments, the gripper mechanism 200 includes a pair of openable grippers 220, which are close to each other in the clamping state and far apart in the unloading state; wherein, when the pair of grippers 220 are close to each other, the pair of grippers 220 limit the clamping space adapted to the outer contour of the clamped portion 880 of the workpiece 800 to be oiled.

[0049] The clamping space of a pair of jaws 220 is adapted to the outer contour of the clamped portion 880 of the workpiece 800, ensuring stable clamping without interfering with the oiling area. The inner wall of the clamping space (i.e., the clamping surface 222 of the jaws 220) can be provided with anti-slip textures, elastic pads, or other structures to enhance clamping stability and prevent damage to the clamped portion 880 of the workpiece 800.

[0050] In some embodiments, the grippers 220 are formed as sheet structures, wherein the thickness of each gripper 220 is in the range of 0.5 mm to 1.5 mm.

[0051] The gripper 220 employs a thin-plate structure, which reduces the contact area with the workpiece 800, preventing the gripper 220 from becoming contaminated with lubricating oil and affecting the workpiece 800 or hindering clamping. It also provides space for the oiling area, ensuring thorough oiling. In a specific example, the gripper 220 can be machined from 1mm thick stainless steel, achieving a thin-plate structure and low manufacturing cost. The thin-plate structure of the gripper 220 ensures both clamping stability and effective oiling. Furthermore, the clamping surface 222 of the gripper 220 can be chamfered or rounded to reduce contact stress with the workpiece 800, protecting the surface of the workpiece 800, making it particularly suitable for clamping soft workpieces such as rubber.

[0052] Figure 5 The structure of the pressure head assembly is shown. Figure 6 The diagram illustrates the three-dimensional structure of the oiling nozzle. (Combined with...) Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the pressure head assembly 400 includes: a fixed base 410 connected to the second moving mechanism 500; an oiling head 420 detachably connected to the fixed base 410, wherein the oiling head 420 is provided with a lubricating oil channel 428, and the end of the oiling head 420 near the support base 100 is provided with a first lubricating oil outlet 429 communicating with the lubricating oil channel 428.

[0053] The pressure head assembly 400 adopts a split design, connected to the second moving mechanism 500 via a fixed base 410. Lubricating oil is delivered through the lubricating oil channel 428 of the oiling head 420 and coated through the first lubricating oil outlet 429. Furthermore, the oiling head 420 is detachably connected to the fixed base 410 for easy replacement and cleaning, improving maintenance convenience.

[0054] Combination Figure 5 and Figure 6 As shown, in some embodiments, the oiling head 420 includes an annular body 421 and a flange 422 extending from a first end 421a of the annular body 421 away from the annular body 421; the flange 422 extends into and is connected to the fixing seat 410; the inner cavity of the flange 422 is connected to a lubricating oil channel 428 disposed in the annular body 421, and the first lubricating oil outlet 429 is evenly distributed at intervals at the second end 421b of the annular body 421 opposite to the first end 421a.

[0055] The oiling head 420 adopts an integrated structure of annular body 421 and flange 422. The flange 422 connects to the fixing seat 410. The uniformly distributed first lubricating oil outlets 429 at the second end 421b of the annular body 421 achieve uniform circumferential oil application to the workpiece. During oiling, lubricating oil flows through the inner cavity of the flange 422 into the lubricating oil channel 428 of the annular body 421 and exits from the first lubricating oil outlet 429 of the annular body 421, thus achieving oiling of the annular area of ​​the workpiece in contact with the oiling head 420.

[0056] Figure 7 The diagram illustrates the cross-sectional structure of the oiling head. (Combined with...) Figure 6 and Figure 7 As shown, in some embodiments, the lubricating oil passage 428 disposed in the annular body 421 includes: a radially extending passage 428a disposed in the first end 421a of the annular body 421, and the first end 421a of the annular body 421 is formed as a sealed end; an axially extending passage 428b disposed in the annular portion of the annular body 421; wherein, the radially extending passage 428a communicates with the inner cavity of the flange 422, the axially extending passage 428b communicates with the radially extending passage 428a and the first lubricating oil outlet 429, and the outlets 428' of the radially extending passage 428a and the axially extending passage 428b located on the outer wall of the annular body 421 are blocked.

[0057] The lubricating oil is guided to the second end 421b of the annular body 421 through the cooperation of the radial extension channel 428a and the axial extension channel 428b, and a sealed delivery is achieved to prevent lubricant leakage. A filter screen, filter element, or other structure can also be installed between the radial extension channel 428a and the axial extension channel 428b to filter impurities.

[0058] In some embodiments, refer to Figure 5 As shown, the oil inlet 427 of the lubricating oil passage 428 is mounted on the fixed base 410, and the fixed base 410 is provided with a channel connecting the oil inlet 427 and the inner cavity of the flange 422. The oil inlet 427 can be formed as a quick connector for easy connection with an external oil supply system.

[0059] In some embodiments, refer to Figure 5 and Figure 6 As shown, the flange 422 and the fixed base 410 are connected by screws or fasteners. This ensures a secure connection and facilitates disassembly and maintenance. For example, the flange 422 and the fixed base 410 are provided with matching pin holes 426', and the two are connected by pins 426, but this is not a limitation. A sealing structure such as a sealing ring can also be provided at the connection between the flange 422 and the fixed base 410 to prevent lubricating oil leakage.

[0060] In some embodiments, refer to Figure 5 As shown, the pressure head assembly 400 also includes: a mounting base 423 connected to the drive output of the second moving mechanism 500; and a floating mechanism 424 connected between the mounting base 423 and the fixed base 410. The floating mechanism 424 allows the oiling head 420 to adaptively fine-tune when it contacts the workpiece, preventing workpiece deformation due to rigid pressing.

[0061] In some embodiments, refer to Figure 5 As shown, the floating mechanism 424 includes: a fastener 424a, one end of which passes through the mounting base 423 and is hooked onto the mounting base 423, and the other end is fixedly connected to the fixed base 410; and an elastic member 424b, which is elastically and telescopically connected between the mounting base 423 and the fixed base 410.

[0062] Fastener 424a passes through mounting base 423 to allow floating and provide restraint, ensuring smooth floating only along the extension direction of fastener 424a; elastic element 424b can compress and absorb impact, protecting the workpiece to be oiled and the oiling head 420. The combination of fastener 424a and elastic element 424b utilizes a simple and reliable structure to enable the oiling head 420 to contact the workpiece to be oiled in a buffered and flexible manner, avoiding damage to the workpiece.

[0063] The fastener 424a can be a screw, serving both a connecting and guiding function, but is not limited thereto. The elastic element 424b can be a spring and sleeved on the fastener 424a, achieving a compact structure and smooth floating, and facilitating assembly and adjustment of the preload, but is not limited thereto.

[0064] In some embodiments, refer to Figure 1 As shown, the support 100 includes: a base 110 with a lubricating oil inlet 111; and a porous material 120 detachably disposed in the base 110, wherein the surface of the porous material 120 forms a bearing surface and the porous material 120 has second lubricating oil outlets evenly distributed at intervals.

[0065] A porous material 120 (such as a sponge, but not limited to) is used to allow lubricating oil to penetrate into the bearing surface through uniformly spaced second lubricating oil outlets, achieving uniform immersion lubrication of the workpiece 800 in contact with the bearing surface. The porous material 120 allows for continuous and uniform lubrication, improving the uniformity and controllability of the lubrication application. The porous material 120 is detachably disposed in the base 110 for replacement or cleaning.

[0066] Continue to refer to Figure 1 As shown, in some embodiments, the first moving mechanism 300 includes: a horizontal moving mechanism 310 having a horizontal moving stroke away from and towards the support 100; a first lifting mechanism 320 connected to a first drive output 311 of the horizontal moving mechanism 310, and a gripper mechanism 200 connected to a second drive output 322 of the first lifting mechanism 320, the first lifting mechanism 320 having a first lifting stroke away from and towards the support 100; the second moving mechanism 500 may be configured as a second lifting mechanism, the pressure head assembly 400 being connected to the drive output of the second lifting mechanism, the second lifting mechanism having a second lifting stroke away from and towards the support 100.

[0067] The first moving mechanism 300 achieves horizontal and vertical combined motion through the horizontal moving mechanism 310 and the first lifting mechanism 320, realizing the precise transportation of the workpiece 800 from the material picking station to the oiling station; the second moving mechanism 500 can control the downward pressing and oiling and the lifting and releasing of the pressure head assembly 400.

[0068] In some embodiments, the oiling apparatus further includes: a workpiece placement fixture 600, and a horizontal moving mechanism 310 having a first working position away from the support seat 100 and close to the workpiece placement fixture 600. Figure 1 The horizontal moving mechanism 310 is located in the first working position, and in the second working position, away from the workpiece placement fixture 600 and close to the support seat 100.

[0069] The workpiece placement fixture 600 serves as a material handling station, separate from the oiling station of the support 100, enabling continuous operation and improving production efficiency. The surface of the workpiece placement fixture 600 can be equipped with positioning grooves, sensors, and other structures to ensure accurate placement of the workpiece 800, facilitating precise material handling and loading.

[0070] In some embodiments, both the first moving mechanism 300 and the second moving mechanism 500 are driven by cylinders, which offer fast response, simple structure, and convenient maintenance, making them suitable for industrial automation scenarios. Of course, besides using cylinders as the drive source, the first moving mechanism 300 and the second moving mechanism 500 can also employ other feasible drive mechanisms. For example, an electric linear module driven by a servo motor or stepper motor can be used to achieve high-precision position control and motion speed adjustment. Alternatively, a hydraulic cylinder can be used to obtain greater output thrust.

[0071] Among them, the support base 100, the first moving mechanism 300, the second moving mechanism 500, the workpiece placement fixture 600 and other components can all be set on the equipment base 700.

[0072] This application also provides a piston dust cover oiling device, which is equipped with an oiling apparatus as described in any of the above embodiments. Figure 8 The structure of the piston dust cover is shown. Figure 9 The diagram illustrates the structure of the grippers holding the piston dust cover. Figure 10 This diagram illustrates the structure of the piston dust cover during the oiling process. (Combined with...) Figure 1 , Figures 8 to 10 As shown, the piston dust cover is provided with a first end 810 and a second end 820 to be oiled. The gripper 220 of the gripper mechanism 200 is configured to grip the gripped portion 880 between the first end 810 and the second end 820 of the piston dust cover. The support seat 100 is configured to support the piston dust cover and apply oil to the first end 810 of the piston dust cover. The pressure head assembly 400 is configured to contact the piston dust cover and apply oil to the second end 820 of the piston dust cover.

[0073] The piston dust cover is held in place by grippers 220, with the gripped portion 880 in the middle. The support 100 applies oil to the lower first end 810 of the piston dust cover, and the pressure head assembly 400 applies oil to the upper second end 820 of the piston dust cover. This achieves simultaneous automated oiling at both ends, replacing manual operation and improving oiling quality and efficiency. The piston dust cover is a core rubber component in braking systems such as hydraulic disc brakes. During assembly, the piston dust cover oiling equipment of this application evenly applies lubricating oil to both ends of the piston dust cover, ensuring its sealing and smooth movement. The grippers 220 are designed to adapt to the structural characteristics of the piston dust cover (e.g., the wrinkles in the gripped portion 880), ensuring stable clamping of the piston dust cover without affecting the oiling operations of the support 100 and the pressure head assembly 400 on the lubricated portions of the piston dust cover.

[0074] Combination Figure 1 and Figure 10As shown, the oiling process of the piston dust cover oiling equipment of this application includes: manually or by automatic mechanical equipment placing the piston dust cover (i.e., workpiece 800) on the workpiece placement fixture 600 → the first lifting mechanism 320 descends → the gripper 220 of the gripper mechanism 200 retracts to a clamping state to clamp the piston dust cover → the first lifting mechanism 320 ascends and leaves the workpiece placement fixture 600 → the horizontal moving mechanism 310 moves to above the support seat 100 → the first lifting mechanism 320 descends to make the piston dust cover contact with the porous material 120 to complete the oiling of the lower first end 810 of the piston dust cover → the second moving mechanism 500 descends to make the oiling head 420 contact the piston dust cover → the oiling head 420 automatically dispenses oil to complete the oiling of the upper second end 820 of the piston dust cover.

[0075] In addition to being suitable for automated oiling of piston dust covers, the oiling device of this application can also be applied to other workpieces requiring oiling. Specifically, the oiling device of this application can be applied to various workpieces that require precise and uniform application of lubricating oil or other protective coatings to inner holes, outer circles, end faces, or specific grooves. These workpieces include rubber oil seals, O-rings, bearing dust covers, sleeves, bushings, and elastomeric components with folds or complex contours. As long as the workpiece has a clamping middle section and an end or specific surface requiring oiling, efficient and uniform automated oiling can be achieved by adapting the corresponding grippers 220, bearing seat 100, and pressure head assembly 400, and adjusting the supply parameters of the lubricating oil or other media.

[0076] Finally, it should be noted that the above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this application and should not be construed as limiting the specific implementation of this application to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this application, and all such modifications or substitutions should be considered within the scope of protection of this application.
