Description

Technical Field

[0001] This invention relates to the field of chip conveyor technology, and more specifically, to a chip conveyor and a machine tool. Background Technology

[0002] Currently, metal chips are generated during the metal processing of CNC machine tools. The chips are usually mixed with coolant and discharged from the machine tool. The metal chips and coolant are then separated by a chip collection device and a water tank.

[0003] However, when CNC machine tools process metal parts, in order to reduce processing time and costs, the toolpath is set to not skip during CNC programming. This results in long chips being produced when milling product parts. These long chips gradually accumulate in the chip conveyor. When the chip conveyor is transported by the chain conveyor, the long chips are formed into chip clumps for transport. When the size of the chip clump is larger than the discharge port of the chip conveyor, the large chip clump will block the discharge port, causing mechanical wear on the chip conveyor and increasing the time required for manual cleaning of the discharge port, thus affecting production efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide a chip conveyor and a machine tool to solve the technical problem that the outlet of the chip conveyor is easily blocked when the chip clumps are too large in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a chip conveyor is provided, comprising:

[0006] The chip conveyor body includes a conveying section for conveying chips;

[0007] A shearing structure is provided on the conveying unit. The shearing structure includes a first shearing part and a second shearing part. Both the first shearing part and the second shearing part are movably provided so as to move to a shearing position where the cutting edge of the first shearing part and the cutting edge of the second shearing part come into contact or to a separation position where the first shearing part and the second shearing part are separated.

[0008] A limiting member is provided on the conveying section and located on the side of the shearing structure away from the inlet of the conveying section. The limiting member and the conveying surface of the conveying section form a limiting opening.

[0009] The contact detection element has its detection end located at the outer edge of the limiting port. The contact detection element is used to detect the contact between the outer edge of the limiting port and the chip.

[0010] The control component, contact detection component, and shearing structure are all connected to the control component to control the movement of the shearing structure to the shearing position or separation position based on the detection result of the contact detection component.

[0011] Furthermore, the chip conveyor also includes a drive structure, the drive end of which is movably disposed, and the first shearing part and the second shearing part are both drivenly connected to the drive end of the drive structure.

[0012] The control component is connected to the drive structure to control the activity of the drive end of the drive structure based on the detection results of the contact detection component.

[0013] Furthermore, the chip conveyor also includes:

[0014] A linkage structure is provided on one side of the shearing structure. The linkage structure includes a sliding track, a first sliding member, and a second sliding member. Both the first and second sliding members are provided in the sliding track. The first sliding member is connected to the first shearing part, and the second sliding member is connected to the second shearing part.

[0015] In this configuration, one of the first and second sliders is movably disposed in a direction that is closer to or further away from the other.

[0016] Furthermore, the chip conveyor also includes a drive structure, the drive end of which is movably disposed. The chip conveyor also includes a first linkage rod and a second linkage rod, one end of the first linkage rod and one end of the second linkage rod are hinged together, the other end of the first linkage rod is connected to a first sliding member, and the other end of the second linkage rod is connected to a second sliding member.

[0017] Wherein, the length of the first linkage rod in the extension direction of the first linkage rod is equal to the length of the second linkage rod in the extension direction of the second linkage rod; and / or,

[0018] One end of the first linkage and one end of the second linkage are both connected to the drive end of the drive structure.

[0019] Furthermore, the chip conveyor also includes:

[0020] A first buffer and a second buffer are provided. The first buffer is located at one end of the sliding track, and the second buffer is located at the other end of the sliding track. The side of the first buffer closer to the first slider is used to abut against the first slider, and the side of the second buffer closer to the second slider is used to abut against the second slider.

[0021] Furthermore, the conveying unit includes a first conveying section and a second conveying section that are connected to each other. The first conveying section is inclined and the second conveying section is horizontal.

[0022] The limiting member and the shearing structure are both located at the connection between the first conveying section and the second conveying section; at least a portion of the first shearing part is attached to the limiting member, and at least a portion of the second shearing part is attached to the limiting member; both the first shearing part and the second shearing part are movably arranged along the extending direction of the limiting member.

[0023] Furthermore, the chip conveyor also includes:

[0024] A cleaning brush is attached to the side of the limiting member close to the shearing structure, and the side of the cleaning brush away from the limiting member is used for frictional contact with the first shearing part and the second shearing part.

[0025] Furthermore, the limiting element includes:

[0026] The first limit segment, the second limit segment, and the third limit segment are connected in sequence. The first limit segment and the third limit segment are set opposite to each other, and the limit port is located between the first limit segment and the third limit segment.

[0027] In this device, one of the first limiting segment and the third limiting segment is movably configured in a direction that moves closer to or further away from the other.

The vision inspection device is used to detect the length of the chip in the extension direction of the conveying section. The control component is connected to the vision inspection device to control the movement frequency of the shearing structure according to the detection result of the vision inspection device.

[0030] According to another aspect of the present invention, a machine tool is provided, comprising: the chip conveyor provided above.

[0031] By applying the technical solution of this invention, the size control of the chips can be optimized. The limiting opening formed by the limiting component and the conveying surface, as well as the contact detection component set on the outer edge of the limiting opening, can dynamically monitor the size of the chips and adjust the position of the shearing structure in a timely manner. This size control mechanism ensures that the size of the chips during the chip removal process will not exceed the size of the limiting opening, thereby avoiding blockage of the limiting opening. Secondly, by setting movable first and second shearing parts on the chip conveyor body, larger chips can be automatically identified and processed, cutting them into smaller chips, thereby preventing chips from entangled or blocking the chip removal opening during the chip removal process, significantly improving the chip removal efficiency and continuous operation capability of the chip conveyor. The connection between the control component, the contact detection component, and the shearing structure realizes automated control of chip size detection and shearing action. No manual periodic replacement and cleaning are required, greatly reducing the need for manual intervention, improving the level of production automation, and saving labor costs. In addition, the combined design of the limiting component and the shearing structure allows for adaptation to different sizes and types of chips, including metal chips and plastic chips, improving the versatility and adaptability of the chip conveyor, making it suitable for various processing environments and materials. Therefore, the technical solution of the present invention can solve the technical problem that the outlet of the chip conveyor is easily blocked when the chip clump is too large in the prior art.

[0056] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0057] like Figures 1 to 4 As shown, Embodiment 1 of the present invention provides a chip conveyor, which includes a chip conveyor body 1, a shearing structure 20, a limiting member 30, a contact detection member, and a control member. The chip conveyor body 1 includes a conveying section 11 for conveying chips. The shearing structure 20 is disposed on the conveying section 11 and includes a first shearing section 21 and a second shearing section 22. Both the first shearing section 21 and the second shearing section 22 are movably disposed to move to a shearing position where the cutting edges of the first shearing section 21 and the second shearing section 22 contact each other or to a separation position where the first shearing section 21 and the second shearing section 22 separate. The limiting member 30 is disposed on the conveying section 11 and located on the side of the shearing structure 20 away from the entrance of the conveying section 11. The limiting member 30 and the conveying surface of the conveying section 11 form a limiting opening 34. The detection end of the contact detection member is disposed at the outer edge of the limiting opening 34, and the contact detection member is used to detect the contact between the outer edge of the limiting opening 34 and the chips. Both the contact detection element and the shearing structure 20 are connected to the control element to control the movement of the shearing structure 20 to the shearing position or the separation position based on the detection result of the contact detection element.

[0058] The chip conveyor provided in Embodiment 1 of this invention firstly optimizes the size control of the chips. The limiting member 30 and the conveying surface form a limiting opening 34, and the contact detection member is located on the outer edge of the limiting opening 34. This allows for dynamic monitoring of the chip size and timely adjustment of the position of the shearing structure 20. This size control mechanism ensures that the size of the chips during the chip conveying process will not exceed the size of the limiting opening 34, thus preventing the limiting opening 34 from being blocked. Secondly, by providing movable first shearing part 21 and second shearing part 22 on the chip conveyor body 1, larger chips can be automatically identified and processed, cutting them into smaller chips. This prevents chips from entangled or blocking the chip conveying opening during the chip conveying process, significantly improving the chip conveying efficiency and continuous operation capability of the chip conveyor. The connection between the control member, the contact detection member, and the shearing structure 20 realizes automated control of chip size detection and shearing action. Regular manual replacement and cleaning are unnecessary, greatly reducing the need for manual intervention, improving the level of production automation, and saving labor costs. Furthermore, the combined design of the limiting component 30 and the shearing structure 20 allows for the adaptation to different sizes and types of chips, including metal chips and plastic chips, improving the versatility and adaptability of the chip conveyor and making it suitable for various processing environments and materials. Therefore, the chip conveyor provided in this embodiment can solve the technical problem in the prior art where the chip conveyor outlet is easily blocked when the chip clump is too large.

[0059] Specifically, when the contact detection element detects that the outer edge of the limiting port 34 is in contact with the chip, it controls the shearing structure 20 to move to the shearing position; when the contact detection element detects that the outer edge of the limiting port 34 is not in contact with the chip, it controls the shearing structure 20 to move to the separation position. In this way, by monitoring the contact state between the chip and the outer edge of the limiting port 34 in real time through the contact detection element, precise chip size control is achieved. When the chip is detected to be in contact with the outer edge of the limiting port 34, it means that the chip size is larger than the limiting port 34, and the shearing structure 20 automatically moves to the shearing position to perform shearing, avoiding blockage and chip jamming caused by excessively large chips, ensuring smooth operation and efficient chip removal of the chip conveyor. Conversely, when the chip is not in contact with the outer edge of the limiting port 34, it means that the chip size is smaller than the limiting port 34, and the shearing structure 20 moves to the separation position, avoiding unnecessary shearing actions, saving energy, and reducing mechanical wear.

[0060] Specifically, the conveyor section 11 is a chain plate structure.

[0061] Specifically, the chip conveyor also includes a drive structure 40, the drive end of which is movably disposed. The first shearing section 21 and the second shearing section 22 are both drivenly connected to the drive end of the drive structure 40. A control unit is connected to the drive structure 40 to control the movement of the drive end of the drive structure 40 based on the detection result of the contact detection unit. This structural arrangement, the integrated design of the drive structure 40 and the shearing structure 20, and the connection with the control unit, achieves automated and precise control of the shearing action. The drive structure 40, connected to the control unit, can respond to the signal from the contact detection unit and quickly adjust the position of the shearing structure 20, improving the response speed and shearing efficiency of the equipment.

[0062] Specifically, the drive structure 40 is a cylinder, and the drive end of the drive structure 40 is vertically adjustable. In this way, the cylinder, as the drive structure, can provide stable and powerful force, ensuring the accurate movement of the shearing structure 20 between the shearing position and the separation position. At the same time, controlling the position of the shearing structure 20 by raising and lowering the drive end makes operation simpler and more efficient, facilitates maintenance and adjustment of the shearing structure 20, and ensures shearing efficiency and quality.

[0063] Specifically, when the contact detection element detects that the outer edge of the limiting port 34 is in contact with the chip, the driving end of the control drive structure 40 moves upward; when the contact detection element detects that the outer edge of the limiting port 34 is not in contact with the chip, the driving end of the control drive structure 40 moves downward. In this way, combining chip contact detection with the cylinder-driven lifting motion achieves intelligent control of the shearing structure 20. When the chip contacts the outer edge of the limiting port 34, the cylinder driving end moves upward, ensuring that the shearing structure 20 is in the shearing position for timely shearing; when the chip is not in contact with the outer edge of the limiting port 34, the driving end moves downward, and the shearing structure 20 is in the separation position, avoiding dry shearing or over-shearing, thus improving the energy efficiency ratio and operational safety of the equipment. This dynamic control method based on contact detection ensures that the chip conveyor handles chips more accurately and flexibly.

[0064] Specifically, the chip conveyor also includes a linkage structure 50, which is disposed on one side of the shearing structure 20. The linkage structure 50 includes a sliding track 51, a first sliding member 52, and a second sliding member 53. Both the first sliding member 52 and the second sliding member 53 are disposed within the sliding track 51. The first sliding member 52 is connected to the first shearing section 21, and the second sliding member 53 is connected to the second shearing section 22. One of the first sliding member 52 and the second sliding member 53 is movably disposed in a direction closer to or further away from the other. This structural arrangement, by setting the linkage structure 50 on one side of the shearing structure 20, achieves precise control and stable movement of the shearing section. The first sliding member 52 and the second sliding member 53 are respectively connected to the first shearing section 21 and the second shearing section 22, allowing the two shearing sections to move smoothly along the sliding track 51, improving the stability and efficiency of the shearing action. This design of the linkage structure 50 ensures accurate alignment of the two shearing sections, reduces deviations during the shearing process, and thus improves the precision and reliability of the shearing.

[0065] Specifically, both the first sliding member 52 and the second sliding member 53 are roller structures. This roller structure allows the sliding members to move within the sliding track 51, reducing friction, improving the smoothness and speed of the movement of the two shearing sections, lowering power requirements, reducing mechanical wear, and extending the equipment's service life. The roller structure design also facilitates rapid positioning of the shearing sections, reducing the time required for adjustment and improving production efficiency.

[0066] Specifically, both the first sliding member 52 and the second sliding member 53 are rubber pulleys.

[0067] Specifically, the sliding track 51 is a straight track.

[0068] In this embodiment, the chip conveyor also includes a drive structure 40, the drive end of which is movably disposed. The chip conveyor also includes a first linkage rod 61 and a second linkage rod 62. One end of the first linkage rod 61 and one end of the second linkage rod 62 are hinged together. The other end of the first linkage rod 61 is connected to a first sliding member 52, and the other end of the second linkage rod 62 is connected to a second sliding member 53. This structural arrangement, integrating the drive structure 40 and the linkage rods, achieves automated control and efficient drive of the shearing structure 20. The drive end of the drive structure 40 is hinged to one end of the first linkage rod 61 and the second linkage rod 62, enabling power transmission through the linkage rods. This allows the first sliding member 52 and the second sliding member 53 to move along the sliding track 51, thereby controlling the shearing action of the two shearing parts. This integrated control method reduces the complexity of the equipment, improves the drive response speed and shearing efficiency, and also simplifies the maintenance process.

[0069] Specifically, the length of the first linkage 61 in its extension direction is equal to the length of the second linkage 62 in its extension direction. This ensures that the two shearing parts remain symmetrical during movement, avoiding possible skewing during the shearing process and further improving the accuracy and effectiveness of the shearing.

[0070] Specifically, one end of the first linkage 61 and one end of the second linkage 62 are both connected to the driving end of the drive structure 40. In this way, the linkages are directly connected to the driving end of the drive structure 40, which reduces energy loss during power transmission, improves power transmission efficiency, and ensures the stable operation of the shear structure 20 and the accurate transmission of shear force.

[0071] Specifically, the chip conveyor also includes a first buffer 71 and a second buffer 72. The first buffer 71 is disposed at one end of the sliding track 51, and the second buffer 72 is disposed at the other end of the sliding track 51. The side of the first buffer 71 closest to the first sliding member 52 is used to abut against the first sliding member 52, and the side of the second buffer 72 closest to the second sliding member 53 is used to abut against the second sliding member 53. This structural arrangement effectively absorbs the impact force of the first sliding member 52 and the second sliding member 53 when they move to the ends of the track, preventing damage to mechanical parts or displacement of the shearing structure 20 due to impact, thus improving the stability and durability of the equipment. Simultaneously, the use of buffers ensures that the shearing section can stop smoothly when it reaches the preset position, reducing noise and improving the working environment.

[0072] Specifically, both the first buffer 71 and the second buffer 72 are urethane anti-collision blocks. In this way, the urethane anti-collision blocks, as buffer components, effectively reduce vibration and noise when the sliding component collides with the end of the track due to their good elasticity and energy absorption properties, protecting the sliding component and the track from impact damage.

[0073] In this embodiment, the conveying unit 11 includes a first conveying section 111 and a second conveying section 112 connected to each other. The first conveying section 111 is inclined, and the second conveying section 112 is horizontal. The limiting member 30 and the shearing structure 20 are both located at the connection between the first conveying section 111 and the second conveying section 112. At least a portion of the first shearing part 21 is attached to the limiting member 30, and at least a portion of the second shearing part 22 is attached to the limiting member 30. Both the first shearing part 21 and the second shearing part 22 are movably arranged along the extending direction of the limiting member 30. This structural arrangement, with the inclined setting of the first conveying section 111 and the horizontal setting of the second conveying section 112, combined with the arrangement of the limiting member 30 and the shearing structure 20, optimizes the conveying path and shearing timing of the chips. The inclined section facilitates the natural sliding of the chips, while the horizontal section provides a stable platform for the shearing operation. This design ensures smooth chip transport and effective chip handling by the shear structure 20, reducing chip accumulation and jamming during transport and improving the chip conveyor's processing capacity and efficiency.

[0074] Specifically, the end of the first conveying section 111 away from the second conveying section 112 is located above the end of the first conveying section 111 that is closer to the second conveying section 112.

[0075] Specifically, the chip conveyor also includes a cleaning brush. The cleaning brush is attached to the side of the limiting member 30 near the shearing structure 20, while the side of the cleaning brush away from the limiting member 30 is used for frictional contact with the first shearing section 21 and the second shearing section 22. With this structural arrangement, the cleaning brush, attached to the side of the limiting member 30 near the shearing structure 20, can rub against the first shearing section 21 and the second shearing section 22, effectively removing residual chips or coolant from the surface of the shearing sections, keeping them clean, and avoiding reduced shearing quality or further jamming problems caused by chip residue. The use of the cleaning brush reduces the need for manual cleaning, improves the level of automation, extends the service life of the shearing sections, reduces maintenance costs, and ensures the long-term stable operation of the chip conveyor.

[0076] In this embodiment, the limiting member 30 includes a first limiting segment 31, a second limiting segment 32, and a third limiting segment 33 connected sequentially. The first limiting segment 31 and the third limiting segment 33 are arranged opposite to each other, and the limiting opening 34 is located between the first limiting segment 31 and the third limiting segment 33. One of the first limiting segment 31 and the third limiting segment 33 is movably arranged in a direction closer to or further away from the other. Both the first limiting segment 31 and the third limiting segment 33 are connected to a control member to control their movement based on the detection result of the contact detection member. This multi-segment limiting member 30 design allows the width of the limiting opening 34 to be dynamically adjusted according to the size of the chip, improving the adaptability of the chip conveyor to chips of different sizes. This allows the size of the limiting opening 34 to be adjusted according to the needs of different chip conveyors, thus facilitating the control of the chip size.

[0077] Specifically, the chip conveyor also includes a vision inspection device, which is located on one side of the inlet of the conveying section 11. The vision inspection device detects the length of the chips in the extending direction of the conveying section 11. A control unit is connected to the vision inspection device to control the movement frequency of the shearing structure 20 based on the detection results. With this structural arrangement, the addition of the vision inspection device allows the chip conveyor to automatically detect the length of the chips in the conveying direction and intelligently adjust the movement frequency of the shearing structure 20 according to the actual size of the chips. This vision-based control mechanism improves the accuracy and efficiency of shearing, avoids over-shearing of short chips or under-shearing of long chips, ensures the consistency of chip size, and improves the convenience and efficiency of subsequent processing.

[0078] Specifically, a control valve is provided on the drive structure 40, and the control valve is connected to the drive end of the drive structure 40. The control valve is used to control the operating frequency of the drive end of the drive structure 40. Specifically, the control valve is a solenoid valve, and the opening degree of the solenoid valve is adjustable to regulate the intake and exhaust of air in the cylinder.

[0079] Specifically, the chip conveyor also includes a chip pusher, which is disposed on the side of the shearing structure 20 away from the limiting member 30. The pushing end of the chip pusher is movably disposed in a direction approaching or away from the limiting port 34. The pushing end of the chip pusher is used to push the chip. Specifically, when the contact detection member detects that the outer edge of the limiting port 34 is in contact with the chip, the shearing structure 20 is controlled to move to the shearing position, and the chip pusher moves in a direction approaching the limiting port 34; when the contact detection member detects that the outer edge of the limiting port 34 is not in contact with the chip, the shearing structure 20 is controlled to move to the separation position, and the chip pusher avoids the chip. Specifically, the pushing end of the chip pusher is a chip pusher plate, and the extending direction of the chip pusher plate is perpendicular to the extending direction of the first conveying section 111. In this way, it can assist in the conveying of the chip, especially when processing large-volume chips or chip clumps. When the contact detection element detects that the chip has contacted the limiting port 34, the shearing structure 20 moves to the shearing position, and at the same time, the chip pusher moves towards the limiting port 34, pushing the chip through the limiting port 34 to ensure stable chip conveying and accurate shearing. When the chip has not contacted the limiting port 34, the chip pusher avoids the chip, preventing interference with the chip conveying process and maintaining its smoothness. The coordinated action of the chip pusher and the shearing structure 20 improves the chip conveyor's chip handling capacity and flexibility, reduces the risk of chip accumulation and jamming during transportation, and ensures a continuous chip conveying process.

[0080] In this embodiment, the chip conveyor also includes a mounting member 80, which is detachably mounted on the chip conveyor body 1. The drive structure 40 is mounted on the mounting member 80 and located above the limiting member 30. Specifically, the mounting member 80 has a triangular structure. This ensures the stability and correct alignment of the drive structure 40 during operation.

[0081] Specifically, to improve safety, the chip conveyor also includes chip-blocking sheet metal. Two chip-blocking sheet metal units are installed on the sides of the shearing structure 20, one on each side, to block splashed chips. Safety light curtains are installed on both sides of the shearing structure 20 to detect personnel approaching. When the safety light curtains detect personnel approaching, the shearing structure 20 stops operating, effectively preventing accidental injury to personnel.

[0082] Specifically, the shearing structure 20 is detachably configured, and the first shearing part 21 and the second shearing part 22 need to be cleaned with anti-rust oil.

[0083] Embodiment 2 of the present invention provides a machine tool, which includes the chip conveyor provided in Embodiment 1.

[0084] The machine tool provided in Embodiment 2 of the present invention firstly optimizes the size control of the chips. The limiting member 30 and the limiting port 34 formed by the conveying surface, as well as the contact detection member set on the outer edge of the limiting port 34, can dynamically monitor the size of the chips and adjust the position of the shearing structure 20 in a timely manner. This size control mechanism ensures that the size of the chips during the chip removal process will not exceed the size of the limiting port 34, thereby avoiding the blocking of the limiting port 34. Secondly, by setting movable first shearing part 21 and second shearing part 22 on the chip conveyor body 1, larger chips can be automatically identified and processed, cutting them into smaller chips, thereby avoiding the chips from entangled or blocking the chip removal port during the chip removal process, significantly improving the chip removal efficiency and continuous operation capability of the chip conveyor. The connection between the control member, the contact detection member, and the shearing structure 20 realizes the automated control of chip size detection and shearing action. There is no need for regular manual replacement and cleaning, which greatly reduces the need for manual intervention, improves the level of production automation, and saves labor costs. Furthermore, the combined design of the limiting component 30 and the shearing structure 20 allows for the adaptation to different sizes and types of chips, including metal chips and plastic chips, improving the versatility and adaptability of the chip conveyor and making it suitable for various processing environments and materials. Therefore, the machine tool provided in this embodiment can solve the technical problem in the prior art where the chip conveyor outlet is easily blocked when the chip clump is too large.

[0085] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: by adding a chip-cutting device to cut the chips, smooth chain conveyor transport is ensured; by using a cylinder to operate the chip-cutting device, the chip conveyor does not require manual periodic replacement and cleaning.

[0088] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0089] 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.

[0090] 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.

[0091] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
