Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a multi-station CD pattern engraving machine. Background Technology

[0002] In today's precision machining field, CD pattern processing, with its decorative and functional properties, is increasingly in demand across numerous industries, including new energy components, automotive parts, smart wearable devices, communication products, and home appliances. Currently, single-station CD pattern processing equipment is common. However, with single-station equipment, the processing steps and workpiece loading / unloading operations cannot be synchronized. Operators must wait for the current workpiece to be processed before loading / unloading the next, resulting in significant time wasted on non-processing steps and severely hindering production efficiency. To address this issue, dual-station equipment has emerged. Dual-station equipment allows workpiece loading / unloading to occur simultaneously at one station, improving efficiency to some extent. However, significant drawbacks remain in practical applications: because the two stations operate independently, even using the same cutting tools, differences in operation between the two stations can reduce the consistency of workpieces in the same batch, leading to decreased product quality stability and consequently affecting product yield, making it difficult to meet the industry's high requirements for mass production. Utility Model Content

[0003] To overcome the problems existing in related technologies, the purpose of this utility model is to provide a multi-station CD pattern engraving machine. This equipment sets at least two sets of rotating modules and uses the same driving element to drive all rotating modules to rotate synchronously, realizing the synchronous rotation of workpieces at multiple stations at the same speed. This effectively solves the problem of processing differences of workpieces in the same batch caused by the independent operation of the stations in existing dual-station equipment, improves the consistency and stability of products in mass production, and thus improves the product yield.

[0004] A multi-station CD pattern engraving machine includes a frame, a worktable, and a tool moving module. The worktable is mounted on the frame, the tool moving module is mounted on the worktable, and a cutting tool assembly is installed on the tool moving module.

[0005] The workbench is equipped with at least two sets of rotating modules for fixing workpiece fixtures, and all the rotating modules rotate synchronously at the same time through a transmission mechanism.

[0006] The transmission mechanism includes a drive element, and the drive element has a rotating shaft with a number of drive pulleys corresponding to the number of rotating modules. Each rotating module has a driven pulley that matches the drive pulley. The driven pulley of each rotating module is connected to the corresponding drive pulley on the drive element's rotating shaft via a conveyor belt.

[0007] Traditional single-station CD pattern processing equipment suffers from low processing efficiency, while dual-station CD pattern processing equipment suffers from significant product variations within the same batch due to the independent operation of the two stations. This solution addresses this issue by setting up at least two sets of rotating modules and using the same drive element to drive all rotating modules synchronously. This achieves synchronous rotation of workpieces at the same speed across multiple stations, effectively solving the problem of processing variations within the same batch of workpieces caused by the independent operation of the stations in existing dual-station equipment. This improves the consistency and stability of products in mass production, thereby increasing product yield. At the same time, the multi-station design retains the advantages of simultaneous processing and loading / unloading in dual-station equipment, avoiding the time wasted in non-processing stages of single-station equipment. While ensuring processing accuracy, it further improves production efficiency, better meeting the industry's demand for high efficiency and consistency in CD pattern processing.

[0008] In a preferred embodiment of this invention, the rotating module includes a fixed ring, which is mounted on the upper surface of the worktable. A drive shaft is provided at the bottom of the fixed ring, and the driven pulley is mounted on the drive shaft.

[0009] The driving element includes a first rotary motor, which is mounted on a frame, and the drive pulley is disposed on the shaft of the first rotary motor.

[0010] This solution ensures the structural rigidity and stability of the rotating module during operation by using a stable connection between the fixed ring and the worktable, combined with the transmission cooperation between the drive shaft and the driven pulley. By using a first rotating motor as the driving element, and with the belt drive method of the active pulley and the driven pulley, it can not only achieve efficient power transmission, but also has a certain buffering and vibration absorption capacity, reducing the wear of components caused by operating impacts.

[0011] In a preferred embodiment of this invention, the fixing ring is provided with a vacuum adsorption hole, a receiving box is installed at the bottom of the fixing ring, a vacuum pump is provided inside the receiving box, and the vacuum pump is connected and cooperated with the vacuum adsorption hole to fix the workpiece fixture.

[0012] The vacuum adsorption holes on the fixing ring of this solution work in conjunction with the vacuum pump inside the housing to quickly and stably fix the workpiece fixture through negative pressure, thereby improving the fixing efficiency and reliability.

[0013] In a preferred embodiment of this invention, the tool moving module includes an X-axis moving component, a Y-axis moving component, and a Z-axis moving component. The X-axis moving component is mounted on one side of the worktable, the Y-axis moving component is mounted on the X-axis moving component, the Z-axis moving component is mounted on the Y-axis moving component, and the cutting tool assembly is mounted on the Z-axis moving component.

[0014] This solution enables precise movement and positioning of the cutting tool assembly in three-dimensional space through the hierarchical installation of X-axis, Y-axis, and Z-axis moving components, meeting the needs of complex machining trajectories. The clear division of labor and coordinated linkage of each axis component can improve the movement accuracy and response speed of the cutting tool assembly, thereby improving the accuracy and efficiency of workpiece machining.

[0015] In a preferred embodiment of this invention, the X-axis moving component includes an X-axis linear motor, and an X-axis connecting seat for horizontal movement is provided on the rotating shaft of the X-axis linear motor. The X-axis connecting seat is fixedly installed with the Y-axis moving component.

[0016] The Y-axis moving component includes a Y-axis linear motor, and a Y-axis connecting seat for horizontal movement is provided on the rotating shaft of the Y-axis linear motor. The Y-axis connecting seat is fixedly installed with the Z-axis moving component.

[0017] The Z-axis moving assembly includes a Z-axis linear motor, and a tool holder for vertical movement is provided on the rotating shaft of the Z-axis linear motor. The cutting tool assembly is mounted on one side of the tool holder.

[0018] This solution uses a linear motor to achieve direct motion transmission in the horizontal and vertical directions, which can reduce transmission errors, ensure more accurate movement trajectory of the cutting tool assembly in three-dimensional space, and thus improve the workpiece machining quality.

[0019] In a preferred embodiment of this invention, the cutting tool assembly includes a rotary cutting head, a first cutting tool for roughing, and a second cutting tool for finishing, wherein the rotary cutting head is mounted on one side of the cutting head mounting base.

[0020] The first and second cutting tools are detachably mounted on a rotary tool head, which is used to switch between the first and second cutting tools for machining.

[0021] The rotary tool turret of this solution can quickly switch between the first tool for roughing and the second tool for finishing, without the need to stop the machine to manually change tools, which greatly improves the continuity and efficiency of machining. The detachable design of the two tools makes it easy to change different types of tools according to machining needs, adapting to a variety of workpieces and machining scenarios.

[0022] In a preferred embodiment of this invention, a mounting ring is provided on one side of the cutter head fixing seat, the rotating cutter head is mounted on the side of the mounting ring closer to the rotating module, and a second rotating motor is mounted on the side of the mounting ring away from the rotating module, the second rotating motor being connected to the rotating cutter head.

[0023] The mounting ring in this design provides a stable mounting platform for the rotary cutter head and the second rotary motor, ensuring their coaxiality and reducing vibration errors during rotation. The second rotary motor directly drives the rotary cutter head, enabling rapid and precise rotation of the cutter head, improving the response speed and positioning accuracy of tool switching, and further ensuring the continuity and stability of machining.

[0024] In a preferred embodiment of this utility model, a first tool holder and a second tool holder are respectively provided on opposite sides of the rotating cutter disc.

[0025] When roughing is performed, the first tool holder of the rotary cutter head rotates to a side away from the cutter head fixing seat; when finishing is performed, the second tool holder of the rotary cutter head rotates to a side away from the cutter head fixing seat.

[0026] In this design, the first tool holder and the second tool holder are screwed onto the first and second turning tools respectively, which facilitates the disassembly and replacement of the turning tools and improves the convenience of tool maintenance. By rotating the tool head, the corresponding tool holder is moved to the side away from the tool head fixing seat for machining, which can avoid interference from other structures in the machining process and ensure the smoothness of roughing and finishing operations.

[0027] In a preferred embodiment of this invention, a cutting tool protective cover is also provided on the cutting tool holder.

[0028] The tool protection cover installed on the tool holder in this solution can effectively block the splashing of chips and coolant generated during machining, which not only protects the tool from the corrosion of impurities to extend its service life, but also reduces the contamination of surrounding parts.

[0029] In a preferred embodiment of this invention, the fixing ring is further provided with a plurality of positioning pin holes for fixing the workpiece fixture.

[0030] The multiple positioning pin holes on the fixed ring of this solution can further achieve precise positioning by cooperating with the positioning pins of the workpiece fixture, effectively limiting the horizontal displacement and rotation of the fixture, and ensuring the stability of the fixture position during processing.

[0031] The beneficial effects of this utility model are as follows:

[0032] This invention achieves synchronous rotation of workpieces at multiple workstations by setting up at least two sets of rotating modules and using the same driving element to drive all rotating modules to rotate synchronously. This effectively solves the problem of processing differences in the same batch of workpieces caused by the independent operation of the workstations in existing dual-workstation equipment, improves the consistency and stability of products in mass production, and thus improves product yield. At the same time, the multi-workstation design retains the advantages of simultaneous processing and loading / unloading in dual-workstation equipment, avoids the time wasted in non-processing stages of single-workstation equipment, and further improves production efficiency while ensuring processing accuracy. It can better meet the industry's demand for high efficiency and consistency in CD pattern processing. Attached Figure Description

[0041] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0042] In today's precision machining field, CD pattern processing, with its decorative and functional properties, is increasingly in demand across numerous industries, including new energy components, automotive parts, smart wearable devices, communication products, and home appliances. Currently, single-station CD pattern processing equipment is common. However, with single-station equipment, the processing steps and workpiece loading / unloading operations cannot be synchronized. Operators must wait for the current workpiece to be processed before loading / unloading the next, resulting in significant time wasted on non-processing steps and severely hindering production efficiency. To address this issue, dual-station equipment has emerged. Dual-station equipment allows workpiece loading / unloading to occur simultaneously at one station, improving efficiency to some extent. However, significant drawbacks remain in practical applications: because the two stations operate independently, even using the same cutting tools, differences in operation between the two stations can reduce the consistency of workpieces in the same batch, leading to decreased product quality stability and consequently affecting product yield, making it difficult to meet the industry's high requirements for mass production.

[0043] Based on this, this application provides a multi-station CD pattern engraving machine.

[0044] Example 1

[0045] See Figures 1 to 6 This embodiment provides a multi-station CD pattern turning machine, including a frame 1, a worktable 2, and a tool moving module. The worktable 2 is set on the frame 1, and the tool moving module is set on the worktable 2. A turning tool assembly is installed on the tool moving module. The frame 1 serves as the basic support structure of the equipment, the worktable 2 is the operating reference surface during workpiece processing, and the tool moving module is used to drive the turning tool assembly to move in space.

[0046] In this embodiment, the worktable 2 is provided with two sets of rotating modules 3 for fixing workpiece fixtures. The workpiece fixture is a clamp installed on the rotating module 3 to fix the workpiece to be processed. The rotating module 3 can drive the workpiece to rotate around its own axis, and cooperate with the cutting tool assembly to complete the circumferential cutting of CD pattern. The two sets of rotating modules 3 achieve synchronous rotation through the transmission mechanism, which is the power transmission structure of the rotating module 3. Traditional single-station CD pattern processing equipment has low processing efficiency, and dual-station CD pattern processing equipment has large differences in the same batch of products due to the independent operation of the two stations. However, in this embodiment, by setting two sets of rotating modules 3 and using the same driving element 4 to drive all rotating modules 3 to rotate synchronously, the synchronous rotation of the workpiece at the same speed in dual stations is achieved.

[0047] Specifically, the transmission mechanism includes a drive element 4, which is the power source of the transmission mechanism. The drive element 4 has a shaft with a number of drive pulleys 5 corresponding to the number of rotating modules 3. Each rotating module 3 has a driven pulley 6 that matches the drive pulley 5. The driven pulley 6 on each rotating module 3 is connected to the corresponding drive pulley 5 on the shaft of the drive element 4 via a conveyor belt 7. The conveyor belt 7 is used to transmit torque to ensure the synchronicity of the movement of the drive pulley 5 and the driven pulley 6, and further ensure the synchronicity of the movement of different rotating modules 3.

[0048] More specifically, the rotating module 3 includes a fixed ring 8, which serves as the basic fixing component of the rotating module 3 and is installed on the upper surface of the worktable 2. A drive shaft 9 is provided at the bottom of the fixed ring 8, and a driven pulley 6 is installed on the drive shaft 9. The drive shaft 9 transmits the power received from the driven pulley 6 to the rotating module 3, driving the workpiece fixture and the workpiece to rotate synchronously. The driving element 4 includes a first rotary motor, which is the core power component of the driving element 4 and is installed on the frame 1. A drive pulley 5 is provided on the shaft of the first rotary motor. The belt drive method in which the drive pulley 5 and the driven pulley 6 cooperate with each other can not only achieve efficient power transmission, but also have a certain buffering and vibration absorption capacity, reducing the wear of components caused by operating impact.

[0049] In actual production applications, the fixing ring 8 is provided with a vacuum adsorption hole 10, which is a through hole opened on the fixing ring 8. A receiving box 11 is installed at the bottom of the fixing ring 8. The receiving box 11 is a box installed at the bottom of the fixing ring 8. A vacuum pump is installed in the receiving box 11. The vacuum pump is a vacuum generating device in the receiving box 11. By extracting the air between the vacuum adsorption hole 10 and the workpiece fixture, a negative pressure is generated. In conjunction with the vacuum adsorption hole 10, the workpiece fixture is quickly and stably adsorbed and fixed, improving the fixing efficiency and reliability.

[0050] Furthermore, the tool movement module includes an X-axis movement assembly 12, a Y-axis movement assembly 13, and a Z-axis movement assembly 14. The X-axis movement assembly 12 is mounted on one side of the worktable 2 and serves as the horizontal transverse movement mechanism of the tool movement module. The Y-axis movement assembly 13 is mounted on the X-axis movement assembly 12 and serves as the horizontal longitudinal movement mechanism of the tool movement module. The Z-axis movement assembly 14 is mounted on the Y-axis movement assembly 13 and serves as the vertical lifting mechanism of the tool movement module. The cutting tool assembly is mounted on the Z-axis movement assembly 14. The X-axis movement assembly 12 includes an X-axis linear motor 15, which serves as the power source for the X-axis movement assembly 12. An X-axis connecting seat 16, which performs horizontal movement, is provided on the rotating shaft of the X-axis linear motor 15. The X-axis connecting seat 16 serves as an intermediate component connecting the X-axis linear motor 15 and the Y-axis movement assembly 13, and is fixed to the Y-axis movement assembly 13. Fixed installation; the Y-axis moving assembly 13 includes a Y-axis linear motor 17 as the power source of the Y-axis moving assembly 13. A Y-axis connecting seat 18 for horizontal movement is provided on the rotating shaft of the Y-axis linear motor 17. The Y-axis connecting seat 18 serves as an intermediate component connecting the Y-axis linear motor 17 and the Z-axis moving assembly 14, and is fixedly installed with the Z-axis moving assembly 14; the Z-axis moving assembly 14 includes a Z-axis linear motor 19 as the power source of the Z-axis moving assembly 14. A tool head fixing seat 20 for vertical movement is provided on the rotating shaft of the Z-axis linear motor 19. The tool head fixing seat 20 is used to fix the turning tool assembly, and the turning tool assembly is installed on one side of the tool head fixing seat 20; by realizing direct motion transmission in the horizontal and vertical directions through the linear motor, transmission errors can be reduced, ensuring that the motion trajectory of the turning tool assembly in three-dimensional space is more accurate, thereby improving the workpiece machining quality.

[0051] Furthermore, the cutting tool assembly includes a rotary cutter head 21, a first cutting tool for roughing, and a second cutting tool for finishing. The first cutting tool is a roughing tool mounted on the rotary cutter head 21, typically with a large depth of cut and feed rate, used to quickly remove most of the machining allowance from the workpiece surface. The second cutting tool is a finishing tool mounted on the rotary cutter head 21, with high cutting accuracy and surface quality requirements, used to finely machine the workpiece surface to form high-precision CD patterns. The rotary cutter head 21 is mounted on one side of the cutter head holder 20. The first and second cutting tools are detachably mounted on the rotary cutter head 21, which is used to switch the machining positions of the first and second cutting tools, enabling rapid conversion between roughing and finishing.

[0052] A mounting ring 24 is provided on one side of the cutter head fixing seat 20. A rotating cutter head 21 is mounted on the side of the mounting ring 24 closest to the rotating module 3, and a second rotary motor 25 is mounted on the side of the mounting ring 24 furthest from the rotating module 3. The second rotary motor 25 is connected to the rotating cutter head 21. The mounting ring 24 provides support and connection for the rotating cutter head 21 and the second rotary motor 25. A first tool holder 22 and a second tool holder 23 are respectively provided on opposite sides of the rotating cutter head 21. The tool holders are used to mount turning tools, and the number of tool holders can be set according to actual production needs. The corresponding number of cutting tools are installed. In this embodiment, the first cutting tool holder 22 is screwed with the first cutting tool, and the second cutting tool holder 23 is screwed with the second cutting tool. When roughing is performed, the first cutting tool holder 22 of the rotating tool head 21 is rotated to the side away from the tool head fixing seat 20. When finishing is performed, the second cutting tool holder 23 of the rotating tool head 21 is rotated to the side away from the tool head fixing seat 20. By rotating the tool head 21, the corresponding cutting tool holders are rotated to the side away from the tool head fixing seat 20 for machining, which can avoid interference from other structures in the machining process and ensure the smoothness of roughing and finishing operations.

[0053] The working process of this embodiment is as follows:

[0054] Two workpieces to be processed are fixed to the fixing rings 8 of the two sets of rotating modules 3 respectively by two workpiece fixtures. The vacuum adsorption hole 10 and the vacuum pump in the accommodating box 11 generate negative pressure to quickly and firmly adsorb the workpiece fixtures. Then, the first rotating motor is started, and the driving pulley 5 on its rotating shaft drives the driven pulleys 6 on the transmission shafts 9 of each rotating module 3 to rotate through the conveyor belt 7, so that the two sets of rotating modules 3 rotate synchronously. At the same time, the X-axis, Y-axis and Z-axis linear motors 19 of the tool moving module drive the X-axis connecting seat 16, Y-axis connecting seat 18 and tool head fixing seat 20 to move respectively, driving the turning tool assembly to adjust in three-dimensional space. At the machining position of the first workpiece, the second rotary motor 25 drives the rotary cutter head 21 to rotate, causing the first cutting tool on the first tool holder 22 to rotate to the side away from the cutter head fixed seat 20, and to perform rough machining in conjunction with the rotating workpiece. After the rough machining is completed, the rotary cutter head 21 switches to the second cutting tool on the second tool holder 23, and performs finishing machining in the same way to form CD patterns. After completion, the cutting tool assembly moves to the machining position of the second workpiece to start machining. While the second workpiece is being machined, the first workpiece can be loaded and unloaded simultaneously. After the current station is completed, the cutting tool assembly moves back to the first station to repeat the operation, realizing continuous machining.

[0055] This invention achieves synchronous rotation of multi-station workpieces by setting up two sets of rotating modules 3 and using the same driving element 4 to drive all rotating modules 3 to rotate synchronously. This effectively solves the problem of processing differences in the same batch of workpieces caused by the independent operation of the workstations in existing dual-station equipment, improves the consistency and stability of products in mass production, and thus improves product yield. At the same time, it retains the advantages of simultaneous processing and loading / unloading in dual-station equipment, avoids the time wasted in non-processing stages of single-station equipment, and further improves production efficiency while ensuring processing accuracy. It can better meet the industry's demand for high efficiency and consistency in CD pattern processing.

[0056] Example 2

[0057] See Figures 1 to 6 This embodiment provides a multi-station CD pattern engraving machine, which differs from Embodiment 1 in that: the worktable 2 is equipped with three sets of rotating modules 3 for fixing workpiece fixtures. The workpiece fixtures are clamps installed on the rotating modules 3 to fix the workpieces to be processed. The rotating modules 3 can drive the workpieces to rotate around their own axes, and cooperate with the cutting tool assembly to complete the circumferential cutting of the CD pattern. The three sets of rotating modules 3 rotate synchronously through a transmission mechanism, which is the power transmission structure of the rotating modules 3. Traditional single-station CD pattern processing equipment has low processing efficiency, and dual-station CD pattern processing equipment has large differences in the same batch of products due to the independent operation of the two stations. However, this embodiment achieves synchronous rotation of workpieces at the same speed by setting three sets of rotating modules 3 and using the same driving element 4 to drive all rotating modules 3 to rotate synchronously.

[0058] The working process of this embodiment is as follows:

[0059] Three workpieces to be processed are fixed onto the fixing rings 8 of the three sets of rotating modules 3 using three workpiece fixtures. The vacuum suction hole 10, in conjunction with the vacuum pump in the housing 11, generates negative pressure to quickly and firmly adsorb the workpiece fixtures. Subsequently, the first rotating motor starts, and the driving pulley 5 on its rotating shaft drives the driven pulleys 6 on the transmission shafts 9 of each rotating module 3 to rotate via the conveyor belt 7, so that the three sets of rotating modules 3 rotate synchronously. At the same time, the X-axis, Y-axis, and Z-axis linear motors 19 of the tool moving module drive the X-axis connecting seat 16, the Y-axis connecting seat 18, and the tool head fixing seat 20 to move, thereby adjusting the cutting tool assembly in three-dimensional space. At the machining position of the first workpiece, the second rotary motor 25 drives the rotary cutter head 21 to rotate, causing the first cutting tool on the first tool holder 22 to rotate to the side away from the cutter head fixed seat 20, and to perform rough machining in conjunction with the rotating workpiece. After the rough machining is completed, the rotary cutter head 21 switches to the second cutting tool on the second tool holder 23 to perform finish machining to form CD patterns. After completion, the cutting tool assembly moves to the machining position of the second workpiece to start machining. While the second workpiece is being machined, the first workpiece can be loaded and unloaded simultaneously. After the current station is completed, the cutting tool assembly moves to the third station to repeat the operation, until multiple round trips are repeated to achieve continuous machining.

[0060] This invention achieves synchronous rotation of workpieces at multiple workstations by setting up three sets of rotating modules 3 and using the same driving element 4 to drive all rotating modules 3 to rotate synchronously. This effectively solves the problem of processing differences in the same batch of workpieces caused by the independent operation of the workstations in existing dual-workstation equipment, improves the consistency and stability of products in mass production, and thus improves product yield. At the same time, the multi-workstation design retains the advantages of simultaneous processing and loading / unloading in dual-workstation equipment, avoids the time wasted in non-processing stages of single-workstation equipment, and further improves production efficiency while ensuring processing accuracy. It can better meet the industry's demand for high efficiency and consistency in CD pattern processing.

[0061] Example 3

[0062] See Figures 1 to 6 The multi-station CD pattern engraving machine provided in this embodiment differs from that in Embodiment 1 or Embodiment 2 in that: the fixing ring 8 is also provided with multiple positioning pin holes for fixing the workpiece fixture. The positioning pin holes are used to insert positioning pins. By cooperating with the corresponding holes of the workpiece fixture, the workpiece fixture is accurately positioned, further ensuring that its installation position is consistent and improving the processing position accuracy.

[0063] A harmonic reducer can also be installed between the rotary module 3 and the drive element 4 to convert the high-speed input of the drive element 4 into the low-speed, high-torque output of the rotary module 3, so that the workpiece can obtain a speed suitable for CD texture processing, while increasing the output torque and ensuring the stability of the processing.

[0064] In this embodiment, a cutting tool protective cover 26 is also provided on the cutting tool holder 20.

[0065] This invention achieves synchronous rotation of workpieces at multiple workstations by setting at least two sets of rotating modules 3 and using the same driving element 4 to drive all rotating modules 3 to rotate synchronously. This effectively solves the problem of processing differences in the same batch of workpieces caused by the independent operation of workstations in existing dual-workstation equipment, improves the consistency and stability of products in mass production, and thus improves product yield. At the same time, the multi-workstation design retains the advantages of simultaneous processing and loading / unloading in dual-workstation equipment, avoids the time wasted in non-processing stages of single-workstation equipment, and further improves production efficiency while ensuring processing accuracy. It can better meet the industry's demand for high efficiency and consistency in CD pattern processing.

[0066] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0067] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
