Description

Technical Field

[0001] This application relates to the technical field of molding and testing equipment for spa massage tubs, and in particular to a molding and testing workbench for spa massage tubs. Background Technology

[0002] After the spa massage tub is formed, quality control is a very important step.

[0003] The existing testing process for molded massage cylinders mainly relies on the coordinated operation of the feeding conveying system, the flipping detection system, and the unloading transfer system.

[0004] The feeding and conveying system includes a horizontally moving frame that moves horizontally along a preset track, a lifting platform mounted on the horizontally moving frame with its lifting end facing downwards, a vertically moving frame connected to the telescopic end of the lifting platform, and a vacuum suction cup assembly integrated on the bottom surface of the vertically moving frame. The vacuum suction cup assembly uses negative pressure to grip the formed massage cylinder. The horizontally moving frame moves horizontally along the preset track, conveying the gripped massage cylinder from the forming station to directly above the flipping detection system. Subsequently, the lifting platform drives the vertically moving frame to move downwards until the clamping mechanism on the flipping detection system clamps the edge of the massage cylinder. Then, the vacuum suction cup assembly releases the massage cylinder, the vertically moving frame moves upwards to reset, and the horizontally moving frame moves horizontally in the opposite direction to reset. The flipping mechanism of the flipping detection system enables the massage cylinder to rotate 0-360° around the horizontal axis, facilitating manual observation of different surface areas. After the inspection is completed, the flipping mechanism of the flipping detection system resets to a horizontal state, and the vertical drive mechanism of the flipping detection system drives the flipping mechanism downwards. The clamping mechanism releases, releasing the massage cylinder onto the top surface of the receiving platform of the unloading and transfer system, completing the entire inspection process.

[0005] However, the aforementioned technologies have the following problems: after the inspection is completed, during the process of the massage cylinder falling from the clamping mechanism to the receiving surface, due to the lack of effective buffering and smooth transition measures, it is easy to cause scratches on the product surface or structural deformation, which in turn affects the product quality and the smooth progress of subsequent processes. Summary of the Invention

[0006] In order to achieve molding inspection and stable material unloading of massage tubs, this application provides a spa massage tub molding inspection workbench.

[0007] The technical solution adopted in this application for a spa massage tub molding and testing workbench is as follows:

[0008] A spa massage tub molding and testing workbench includes a frame, a lifting mechanism mounted on the frame, a flipping mechanism connected to the lifting end of the lifting mechanism, a clamping mechanism mounted on the flipping mechanism, a conveying mechanism mounted in the frame and located below the flipping mechanism, and a receiving mechanism mounted on the conveying mechanism. The supporting end of the receiving mechanism is vertically movable and is used to support the massage tub falling from the clamping mechanism, so that the massage tub can fall relatively smoothly onto the receiving surface of the receiving mechanism.

[0009] By adopting the above technical solution, the lifting mechanism on the frame can realize the lifting action of the flipping mechanism, thereby meeting the operation requirements of different heights; the cooperation between the flipping mechanism and the clamping mechanism allows the massage cylinder to be flipped during the inspection process, which facilitates comprehensive observation and inspection of its surface quality; the setting of the conveying mechanism and the receiving mechanism not only realizes the automatic conveying of the massage cylinder after inspection, but also ensures that the process of the massage cylinder falling from the clamping mechanism to the receiving surface is more stable through the vertical movement function of the support end of the receiving mechanism, avoiding damage that may be caused by direct drop; thus realizing the forming inspection and stable receiving of the massage cylinder.

[0010] Optionally, the receiving mechanism includes a base frame, a receiving plate fixedly connected to the top surface of the base frame, and a support assembly disposed inside the base frame. The conveying mechanism is used to convey the base frame. The support end of the support assembly can move vertically and support the massage cylinder. The top surface of the receiving plate is provided with a clearance opening corresponding to the position of the support end of the support assembly.

[0011] By adopting the above technical solution, the bottom frame cooperates with the conveying mechanism to ensure that the receiving mechanism can move with the conveying mechanism; the receiving plate provides the final receiving surface for the massage cylinder; the supporting end of the support assembly can move vertically, which can smoothly lift the massage cylinder from the clamping mechanism and transfer it to the receiving plate after the inspection is completed, avoiding damage that may be caused by direct dropping; the design of the clearance opening allows the supporting end of the support assembly to extend smoothly above the receiving plate to complete the supporting action of the massage cylinder.

[0012] Optionally, the conveying mechanism includes a base and a conveying assembly disposed on the base. The conveying assembly is used to convey the bottom frame. Guide rails that are slidably connected to the bottom frame are fixedly connected to the top surfaces of both sides of the base. A support plate is fixedly connected between the two sides of the base. A drive motor for driving the support end of the support assembly to move vertically is installed on the top surface of the support plate.

[0013] By adopting the above technical solution, the stable sliding and conveying of the bottom frame on the base is achieved. At the same time, the support plate effectively supports the conveying components, ensuring the stability of the conveying process.

[0014] Optionally, a drive rod is fixedly connected to the drive end of the drive motor, and a polygonal shaft is fixedly connected to the end of the drive rod away from the drive motor. The support assembly includes a mounting frame installed on the bottom wall of the bottom frame, two movable rods that are slidably connected to the mounting frame and the top frame respectively, a screw that is rotatably connected to the mounting frame and threadedly connected to the movable rods, and a first hinge arm and a second hinge arm that are cross-arranged and connected between the mounting frame and the top frame. A polygonal groove is provided on the end of the screw near the drive rod to engage with the polygonal shaft.

[0015] By adopting the above technical solution, the drive motor can drive the polygonal shaft to rotate through the drive rod. The polygonal shaft is engaged with the polygonal slot on the screw, thereby realizing the drive motor driving the screw. When the screw rotates, the moving rod threadedly connected to the screw moves laterally within the mounting frame, and then drives the top frame to move vertically through the linkage of the first hinge arm and the second hinge arm. This design enables the support end of the support assembly to move vertically accurately, so that after the inspection is completed, the massage cylinder can be smoothly transferred from the clamping mechanism to the receiving plate, avoiding damage to the massage cylinder during the unloading process and improving the efficiency and safety of the inspection work.

[0016] Optionally, the lifting mechanism includes a vertical drive assembly mounted on a frame and a connecting arm connected to the drive end of the vertical drive assembly and sliding vertically on the frame. A fixed seat is mounted on the frame, and a buffer cylinder for buffering the connecting arm is fixedly mounted on the fixed seat. A triggering assembly for triggering the drive motor is also mounted on the fixed seat.

[0017] By adopting the above technical solution, the vertical movement of the connecting arm is buffered, effectively reducing the impact caused by inertia when the connecting arm reaches the end of its stroke, and improving the stability of the equipment operation. At the same time, by setting a trigger component, the drive motor can be automatically triggered during the downward movement of the connecting arm, so that the support end of the receiving mechanism can support the massage cylinder in time, ensuring that the massage cylinder can smoothly transition to the receiving surface and avoid damage caused by sudden material drop.

[0018] Optionally, the triggering assembly includes a fixed cylinder vertically mounted on the bottom surface of the fixed base and located between two buffer cylinders, a proximity switch mounted on the bottom wall of the fixed cylinder, a trigger rod vertically penetrating the fixed base and the fixed cylinder in sequence, an abutment block fixedly connected to the top of the trigger rod, and a spring sleeved around the trigger rod and located between the abutment block and the fixed base. The proximity switch is electrically connected to the drive motor through a central controller.

[0019] By adopting the above technical solution, when the connecting arm moves down and presses against the abutment block, the trigger rod moves downward under force until the bottom end of the trigger rod touches the proximity switch; after the proximity switch is triggered, the drive motor is started through the central controller, and the drive motor drives the support end of the support assembly to move upward, thereby supporting the massage cylinder falling from the clamping mechanism and ensuring that the massage cylinder smoothly transitions to the receiving plate.

[0020] Optionally, the flipping mechanism includes a power assembly disposed on the outside of the connecting arm and a flipping frame rotatably connected to the connecting arm, wherein the power assembly is used to drive the flipping frame to flip relative to the connecting arm.

[0021] By adopting the above technical solution, the power component drives the flip frame to rotate, making it easier for staff to observe the surface of the massage tank from multiple angles to check for defects, thus improving detection efficiency and accuracy.

[0022] Optionally, the flipping frame includes two parallel longitudinal arms and two transverse arms perpendicular to the longitudinal arms. The longitudinal arms are rotatably connected to the connecting arm, and the interior of the longitudinal arms is provided with an adjustment component that causes the two transverse arms to move in opposite directions.

[0023] By adopting the above technical solution, the flipping frame is composed of two longitudinal arms and two transverse arms, forming a stable rectangular frame structure that can provide a reliable installation foundation for the clamping mechanism. The longitudinal arms are rotatably connected to the connecting arms, allowing the flipping frame to rotate relative to the lifting mechanism, thereby enabling multi-angle detection of the massage cylinder. The adjustment components inside the longitudinal arms drive the two transverse arms to move in opposite directions, which can flexibly adjust the distance between the clamping mechanisms to accommodate massage cylinders of different sizes, thus improving the versatility and applicability of the equipment.

[0024] Optionally, the clamping mechanism includes a mounting base mounted on the top surface of the transverse arm, a fixed clamping plate fixedly connected to the top of the mounting base, a pneumatic clamp mounted on the mounting base, and a movable clamping plate mounted on the moving end of the pneumatic clamp.

[0025] By adopting the above technical solution, the mounting base provides a stable mounting foundation for the fixed clamp plate and the pneumatic clamp. The fixed clamp plate is used to support the edge of the massage cylinder, and the pneumatic clamp drives the moving clamp plate to move, thereby pressing the edge of the massage cylinder between the moving clamp plate and the fixed clamp plate, ensuring that the massage cylinder will not loosen or fall off during the flipping test, thus improving the safety and reliability of the test work.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The lifting mechanism on the frame enables the lifting action of the flipping mechanism, thereby meeting the operation requirements at different heights; the cooperation between the flipping mechanism and the clamping mechanism allows the massage cylinder to flip during the inspection process, facilitating comprehensive observation and inspection of its surface quality; the setting of the conveying mechanism and the receiving mechanism not only enables the automatic conveying of the massage cylinder after inspection, but also ensures a smoother process of the massage cylinder falling from the clamping mechanism to the receiving surface through the vertical movement function of the support end of the receiving mechanism, avoiding potential damage caused by direct drop; thus realizing the forming inspection and smooth receiving of the massage cylinder.

[0028] 2. The drive motor can drive the polygonal shaft to rotate via the drive rod. The polygonal shaft is engaged with the polygonal slot on the screw, thereby enabling the drive motor to drive the screw. When the screw rotates, the moving rod threadedly connected to the screw moves laterally within the mounting frame, and then, through the linkage of the first and second hinge arms, drives the top frame to move vertically. This design allows the support end of the support assembly to move vertically precisely, so that after the inspection is completed, the massage cylinder can be smoothly transferred from the clamping mechanism to the receiving plate, avoiding damage to the massage cylinder during the unloading process and improving the efficiency and safety of the inspection work.

[0029] 3. When the connecting arm moves down and presses against the abutment block, the trigger rod moves downward under force until the bottom of the trigger rod touches the proximity switch; after the proximity switch is triggered, the drive motor is started through the central controller, and the drive motor drives the support end of the support assembly to move upward, thereby supporting the massage cylinder falling from the clamping mechanism and ensuring that the massage cylinder smoothly transitions to the receiving plate.

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0040] This application discloses a workbench for testing the molding of a spa massage tub. (Refer to...) Figure 1 and Figure 2 The spa massage tub molding and testing workbench includes a frame 1, a lifting mechanism mounted on the frame 1, a flipping mechanism connected to the lifting end of the lifting mechanism, a clamping mechanism mounted on the flipping mechanism, a conveying mechanism mounted in the frame 1 and located below the flipping mechanism, and a receiving mechanism mounted on the conveying mechanism. The supporting end of the receiving mechanism can move vertically and is used to support the massage tub falling from the clamping mechanism. Then, the supporting end of the receiving mechanism moves down so that the massage tub falls more smoothly onto the receiving surface of the receiving mechanism.

[0041] The lifting mechanism includes a vertical drive assembly mounted on the frame 1 and a connecting arm 2 connected to the drive end of the vertical drive assembly and sliding vertically on the frame 1. There are two connecting arms 2, which are symmetrically arranged on the frame 1. The number of vertical drive assemblies is the same as the number of connecting arms 2 and they correspond one-to-one. The flipping mechanism is connected between the two connecting arms 2.

[0042] Slider 21 is fixedly connected to both end faces of the connecting arm 2. A slide rail 11 is installed on the frame 1 and is slidably connected to the slider 21. The slide rail 11 is vertically arranged in the length direction. There are two sliders 21 on the same end face of the connecting arm 2. The two sliders 21 are symmetrically arranged on the end face of the connecting arm 2. The number of slide rails 11 is the same as the number of sliders 21 and they correspond one-to-one. Thus, under the sliding connection between the slider 21 and the corresponding slide rail 11, the vertical sliding of the connecting arm 2 is realized.

[0043] The vertical drive assembly includes a vertical drive member 3 vertically mounted on the frame 1 and located above the slide rail 11, a vertical lead screw 31 vertically positioned and fixedly connected to the drive end of the vertical drive member 3, and a threaded block 32 threadedly connected to the vertical lead screw 31 and fixedly connected to the end face of the connecting arm 2; the threaded block 32 is located between two sliders 21 on the same end face of the connecting arm 2. Thus, the vertical drive member 3 drives the vertical lead screw 31 to rotate, and under the limiting action of the sliders 21 and the slide rail 11, the vertical lead screw 31 drives the connecting arm 2 to move vertically through the threaded block 32.

[0044] In this embodiment, both vertical drive components 3 are servo motors, and both servo motors are equipped with high-precision encoders (not shown in the figure) to collect the angular displacement signal of the servo motor rotor in real time. One of the servo motors is set as the master motor and the other servo motor is set as the slave motor. The central controller receives the signals from the two encoders and calculates the real-time angular displacement difference Δθ between the master motor and the slave motor. If Δθ exceeds the threshold of 0.05°, the output torque of the slave motor is adjusted by the PID algorithm until Δθ≤0.05°. The adjusted torque command is then sent to the driver of the slave motor to achieve synchronous control of the master motor and the slave motor.

[0045] Reference Figure 1 and Figure 3 The flipping mechanism includes a power assembly mounted on the outside of one of the connecting arms 2 and a flipping frame rotatably connected between the two connecting arms 2. The power assembly includes a power component 4 and a reducer 41 mounted on the outside of one of the connecting arms 2. The drive end of the power component 4 is fixedly connected to the input end of the reducer 41, and the output end of the reducer 41 passes through the connecting arm 2 and is fixedly connected to one side of the flipping frame, so that the flipping frame can flip relative to the connecting arm 2. In this embodiment, the power component 4 is a motor.

[0046] Reference Figure 1 and Figure 2The flip frame includes two parallel longitudinal arms 42 and two transverse arms 43 perpendicular to the longitudinal arms 42. The two transverse arms 43 are located between the two longitudinal arms 42, and the two longitudinal arms 42 are located between two connecting arms 2. The longitudinal arms 42 are rotatably connected to the corresponding connecting arms 2. An adjustment component is provided inside one of the longitudinal arms 42. The adjustment component is connected to the two transverse arms 43 so that the two transverse arms 43 can move in opposite directions. A clamping mechanism is provided on the top surface of the transverse arm 43, and multiple sets of clamping mechanisms are provided on the same transverse arm 43. The multiple sets of clamping mechanisms are evenly distributed on the transverse arm 43.

[0047] Each of the two longitudinal arms 42 has an adjustment groove 421 on one side that is close to each other. The length direction of the adjustment groove 421 is consistent with the length direction of the longitudinal arm 42. There are two adjustment grooves 421 on the same longitudinal arm 42. The two adjustment grooves 421 on the same longitudinal arm 42 are located at the two ends of the longitudinal arm 42 respectively. Guide blocks 431 are fixedly connected to the opposite ends of the transverse arm 43. The guide blocks 431 are slidably connected to the adjustment grooves 421 corresponding to the positions.

[0048] The adjustment assembly includes a dual-axis motor installed inside one of the longitudinal arms 42 and located between two adjustment slots 421, and two threaded rods 44 respectively fixedly connected to the two drive ends of the dual-axis motor. The length direction of the threaded rods 44 is consistent with the length direction of the adjustment slots 421, and the threaded rods 44 are rotatably connected in the corresponding adjustment slots 421. The threads on the two threaded rods 44 on the same longitudinal arm 42 have opposite directions of rotation. The threaded rods 44 pass through the corresponding guide blocks 431 and are threadedly connected to the guide blocks 431. Thus, under the drive of the dual-axis motor, the two transverse arms 43 move in opposite directions, enabling the clamping mechanism to clamp massage cylinders of different sizes.

[0049] Reference Figure 1 and Figure 4 The clamping mechanism includes a mounting base 5 mounted on the top surface of the transverse arm 43, a fixed clamping plate 51 fixedly connected to the top of the mounting base 5, a pneumatic clamp 52 mounted on the mounting base 5, and a movable clamping plate 53 mounted on the moving end of the pneumatic clamp 52. When the top surface of the fixed clamping plate 51 supports the edge of the massage cylinder, the pneumatic clamp 52 is activated, causing the moving end of the pneumatic clamp 52 to drive the movable clamping plate 53, thereby clamping the edge of the massage cylinder between the movable clamping plate 53 and the fixed clamping plate 51, completing the clamping action. In this embodiment, the pneumatic clamp 52 is model GH-20820-A.

[0050] Reference Figure 5 and Figure 6The conveying mechanism includes a base 6 and a conveying assembly mounted on the base 6. The base 6 is located within the frame 1 and below the tilting frame. The conveying assembly is used to convey the receiving mechanism. The conveying assembly includes a conveying drive 61, a rotating rod 62, a sprocket 63, and a chain 64. The conveying drive 61 is longitudinally mounted on one end of the base 6. The rotating rod 62 is longitudinally positioned along its length and rotatably connected between the two sides of the base 6. Two rotating rods 62 are provided, located at opposite ends of the base 6. The driving end of the conveying drive 61 is fixedly connected to the end of one of the rotating rods 62. The sprocket 63 is fixedly sleeved on the circumference of the rotating rod 62, and two sprockets 63 are provided on the same rotating rod 62, located at both ends of the rotating rod 62. The two sprockets 63 located in the same transverse direction are engaged with the same chain 64. A support plate 65 is fixedly connected between the two sides of the base 6 and between the two rotating rods 62. The support plate 65 extends to the hollow part of the chain 64 to support the chain 64.

[0051] Reference Figure 6 and Figure 7 The receiving mechanism includes a base frame 7, a receiving plate 71 fixedly connected to the top surface of the base frame 7, and a support assembly disposed inside the base frame 7. The support end of the support assembly can move vertically, and a clearance opening 711 corresponding to the position of the support end of the support assembly is provided on the top surface of the receiving plate 71, so that the support end of the support assembly can extend to the top surface of the receiving plate 71 through the clearance opening 711.

[0052] Guide rails 66 are fixedly connected to the top surfaces of both sides of the base 6. The length direction of the guide rails 66 is consistent with the length direction of the base 6. Guide grooves 72 corresponding to the positions of the guide rails 66 are formed on the bottom surface of the base frame 7. The guide grooves 72 are slidably connected to the corresponding guide rails 66. There is a certain gap between the guide rails 66 and the guide grooves 72 so that the bottom surface of the base frame 7 can always overlap the top surface of the chain 64, thereby realizing the conveying of the base frame 7 by the chain 64.

[0053] The support assembly includes a mounting frame 73, a moving rod 74, a screw 75, a first hinge arm 76, a second hinge arm 77, and a top frame 78. The mounting frame 73 is installed on the inner bottom wall of the bottom frame 7. The mounting frame 73 has a first elongated hole 731 on both sides, and the top frame 78 has a second elongated hole 781 on both sides. The length direction of the first elongated hole 731 and the length direction of the second elongated hole 781 are both consistent with the length direction of the guide rail 66. There are two moving rods 74. The moving rod 74 located in the mounting frame 73 is slidably connected to the mounting frame 73 through the first elongated hole 731, and the moving rod 74 located in the top frame 78 is slidably connected to the top frame 78 through the second elongated hole 781.

[0054] The first hinge arm 76 and the second hinge arm 77 are arranged crosswise and hinged to each other. There are two sets of the first hinge arm 76 and the second hinge arm 77, which are respectively located at opposite ends of the moving rod 74. The bottom end of the first hinge arm 76 is hinged to the end of the moving rod 74 located in the mounting frame 73, and the top end of the first hinge arm 76 is hinged to the inner end of the top frame 78. The bottom end of the second hinge arm 77 is hinged to the inner end of the mounting frame 73, and the top end of the second hinge arm 77 is hinged to the moving rod 74 located in the top frame 78.

[0055] The screw 75 is rotatably connected within the mounting frame 73, and the length direction of the screw 75 is perpendicular to the length direction of the moving rod 74. The screw 75 passes through the moving rod 74 located within the mounting frame 73, and the screw 75 is threadedly connected to the moving rod 74 located within the mounting frame 73. The top frame 78 corresponds to the clearance opening 711. Thus, when the screw 75 is rotated, the screw 75 drives the moving rod 74 to move laterally. Under the connection of the first hinge arm 76 and the second hinge arm 77, the top frame 78 moves upward, so that the top frame 78 can extend above the top surface of the receiving plate 71 through the clearance opening 711.

[0056] A drive motor 651 for driving the screw 75 to rotate is installed on the top surface of the support plate 65. A drive rod 652 is fixedly connected to the drive end of the drive motor 651. A polygonal shaft is fixedly connected to the end of the drive rod 652 away from the drive motor 651. A polygonal groove 751 corresponding to and matching the position of the polygonal shaft is opened on the end of the screw 75 near the drive rod 652. When the chain 64 conveys the bottom frame 7, the drive rod 652 passes through the bottom frame 7 and the mounting frame 73 in sequence until the polygonal shaft is inserted into the polygonal groove 751, so that the drive motor 651 can drive the screw 75 to rotate.

[0057] Reference Figure 4 and Figure 8 A fixed base 12 is installed on the frame 1 and at the bottom of the slide rail 11. Two symmetrically arranged buffer cylinders 121 are fixedly inserted on the fixed base 12. The buffer end of the buffer cylinder 121 is set upward. The buffer cylinder 121 is used to buffer the connecting arm 2. A triggering component for triggering the drive motor 651 is provided on the fixed base 12.

[0058] The triggering assembly includes a fixed cylinder 122 vertically mounted on the bottom surface of the fixed base 12 and located between two buffer cylinders 121, a proximity switch 123 mounted on the inner bottom wall of the fixed cylinder 122, a trigger rod 124 vertically penetrating the fixed base 12 and the fixed cylinder 122 in sequence, an abutment block 125 fixedly connected to the top of the trigger rod 124, and a spring 126 sleeved around the trigger rod 124 and located between the abutment block 125 and the fixed base 12; the proximity switch 123 is electrically connected to the drive motor 651 through a central controller.

[0059] The implementation principle of the spa massage tub molding and testing workbench in this application embodiment is as follows: The massage tub is transported to the top surface of the fixed clamping plate 51, with the protrusion of the massage tub facing downwards. The pneumatic clamp 52 is activated to clamp the edge of the massage tub between the moving clamping plate 53 and the fixed clamping plate 51. The power component 4 is activated to flip the rotating frame, allowing the operator to observe whether there are any defects on the surface of the massage tub. After the test is completed, the power component 4 is used to make the rotating frame horizontal, with the protrusion of the massage tub facing upwards. The vertical drive component 3 is activated to make the connecting arm 2 move the rotating frame downwards, and the connecting arm 2 is buffered by the buffer cylinder 121. At the same time, the connecting arm 2 begins to press the abutment block 125, so that the spring 12 6 is in a compressed state until the bottom end of the trigger rod 124 triggers the proximity switch 123. The proximity switch 123 starts the drive motor 651 through the central controller. Under the drive of the drive motor 651, the top frame 78 gradually moves upward until the top frame 78 supports the top of the inner wall of the massage cylinder. At this time, the moving end of the pneumatic clamp 52 moves in the opposite direction to release the clamp on the edge of the massage cylinder. Then, the drive motor 651 rotates in the opposite direction to make the top frame 78 gradually move downward until the top surface of the receiving plate 71 receives the massage cylinder, completing the smooth receiving of the massage cylinder. After that, the conveying drive 61 is started to drive the bottom frame 7 to move in the direction of discharge through the chain 64, thereby conveying the receiving mechanism together with the detected massage cylinder to the next process.

[0060] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
