Description

Technical Field

[0001] This utility model relates to the field of semiconductor packaging technology, and in particular to a material clamping device. Background Technology

[0002] In modern semiconductor packaging processes, increased automation places higher demands on production efficiency and product quality. In this process, the clamping mechanism, as a key component, is responsible for the automated loading and unloading of cartridges (often called clips) on the production line. Traditional clamping mechanisms typically require parameter settings based on the height of the cartridges to ensure accuracy during the clamping process. However, with the diversification of production needs, cartridge heights are often inconsistent, and cartridges of different heights may be mixed within the same production batch.

[0003] In traditional solutions, to address the compatibility issues of boxes of different heights, the following approaches are typically adopted: screening the boxes before loading to ensure that the boxes entering the production line are of uniform height. While this method is simple, it requires additional screening steps, leading to reduced production efficiency. Alternatively, a dedicated clamping mechanism or a different structure can be designed for each type of box. Although this method can solve the compatibility problem, it requires additional equipment investment, increases costs, and necessitates frequent equipment changes during production, affecting the continuity and efficiency of the production line.

[0004] Therefore, traditional solutions suffer from inefficiency and high cost when dealing with compatibility issues of boxes of different heights. These problems limit the flexibility and economy of the production line, necessitating a material clamping mechanism that can automatically adapt to boxes of different heights to improve production efficiency and reduce costs.

[0005] The above information disclosed in the background art of this utility model is only used to understand the background of the concept of this utility model, and may include information that does not constitute prior art. Utility Model Content

[0006] Therefore, it is necessary to provide a material clamping device to address the above problems.

[0007] A material clamping device, comprising:

[0008] frame;

[0009] A positioning device, which is disposed on the frame and used to abut against the side of the material box to position the material box;

[0010] A lifting device, wherein the lifting device is mounted on the frame;

[0011] A clamping device is provided, which can move up and down relative to the frame under the drive of the lifting device. The clamping device includes a bracket, a connecting rod assembly, a pressure plate and an elastic element connected to the lifting device. One end of the connecting rod assembly is rotatably connected to the bracket, and the other end of the connecting rod assembly is rotatably connected to the pressure plate. The elastic element is connected between the pressure plate and the bracket.

[0012] When clamping the material box, the positioning device abuts against the side of the material box, the clamping device can descend under the drive of the lifting device and make the pressure plate abut against the top of the material box, and the pressure plate can overcome the elastic force of the elastic element under the force of the material box and make the connecting rod assembly rotate in a direction away from the material box. The elastic force provided by the elastic element can make the pressure plate have a tendency to press down on the top of the material box; the clamping device can also rise under the drive of the lifting device to separate the pressure plate from the top of the material box.

[0013] The aforementioned material clamping device achieves at least the following beneficial effects: Firstly, the lifting and clamping devices can automatically adjust the position of the pressure plate to adapt to boxes of different heights, thereby eliminating the need for height screening of the boxes and improving the flexibility and efficiency of the production line. Secondly, the combined design of the linkage assembly and elastic element allows the pressure plate to reliably clamp or release the boxes. The elastic force provided by the elastic element ensures that the pressure plate can stably apply pressure to the top of the box, maintaining reliable clamping performance even when faced with boxes of varying heights. This significantly improves operational safety and stability. This versatile design not only reduces the manufacturing and maintenance costs of the equipment but also avoids the need to design dedicated clamping mechanisms for boxes of different heights, effectively solving the problems of low efficiency, high cost, and insufficient flexibility in traditional technologies, providing a highly efficient, economical, and reliable solution for the production line.

[0014] In some embodiments, the support includes a vertical frame connected to the lifting device and a crossbeam connected to the vertical frame. One end of the linkage assembly is rotatably connected to the end of the crossbeam away from the vertical frame, and the other end of the linkage assembly is rotatably connected to the pressure plate, which is located below the crossbeam. The elastic element includes a tension spring, with a first end fixed to the vertical frame and a second end fixed to the pressure plate. When the pressure plate clamps the material box, the first end is lower than the second end in the height direction and the tension spring is in a stretched state, so that the tension of the tension spring can cause the pressure plate to have a tendency to press down on the top of the material box. The elastic element is a tension spring, with its first end fixed to the upright and its second end fixed to the pressure plate. This configuration ensures that when the pressure plate clamps the material box, the first end of the tension spring is lower than the second end in the height direction and is under tension, thus providing a downward pulling force. This force allows the pressure plate to tend to press down on the top of the material box when it abuts against it, ensuring a stable and reliable clamping effect even when handling material boxes of inconsistent heights. The overall design not only improves the operating efficiency and safety of the equipment but also further enhances the flexibility and adaptability of the production line by reducing the need for height screening.

[0015] In some embodiments, the pressure plate includes a first pressure plate rotatably connected to one end of the connecting rod assembly and a second pressure plate stacked on top of the first pressure plate. The top of the first pressure plate is fixed to the first end of the tension spring. The second pressure plate is located on the side of the first pressure plate facing away from the crossbeam and is a flexible plate. The top of the first pressure plate is fixed to the first end of the tension spring, enabling it to effectively transmit the tension of the spring and ensuring that the second pressure plate connected to the first pressure plate has sufficient downward pressure when clamping the material box. The second pressure plate is located on the side of the first pressure plate facing away from the crossbeam and is made of a flexible material (such as urethane rubber), which can effectively absorb and mitigate pressure fluctuations during clamping, protect the material box from damage caused by excessive pressure, and improve the stability and safety of clamping.

[0016] In some embodiments, the end of the crossbeam away from the upright extends downward to form a bend, the pressure plate is located on the side of the bend facing the upright, and the first end of the tension spring is fixed to the bend. The crossbeam is designed to extend downward to form a bend at the end away from the upright, and the first end of the tension spring is fixed to the bend. This connection ensures that the tension spring can effectively apply tension, giving the pressure plate sufficient downward pressure to achieve a stable clamping effect.

[0017] In some embodiments, the clamping device includes a first adjusting member threadedly through the bend. One end of the first adjusting member abuts against the pressure plate, and the other end is operable to adjust the tension of the tension spring. When the pressure plate clamps the cassette, the pressure plate can move away from the first adjusting member under pressure from the top of the cassette, further stretching the tension spring. The first adjusting member is threaded through the bend, allowing for flexible position adjustment. The abutment of one end of the first adjusting member against the pressure plate allows the user to adjust the tension of the tension spring via the other end. In the clamped position, when the pressure plate is compressed from the top of the cassette, it can move away from the first adjusting member. This movement further stretches the tension spring, increasing the system's elasticity and clamping force on the cassette. This design not only provides precise control of the clamping force but also allows for rapid adjustment of the tension spring under different operating conditions to accommodate cassettes of different sizes.

[0018] In some embodiments, the linkage assembly includes a connecting rod and a pivot shaft connected to one end of the connecting rod. The other end of the connecting rod is rotatably connected to the pressure plate. The pivot shaft rotatably passes through the crossbeam. The elastic element also includes a torsion spring disposed on the pivot shaft. When the pressure plate clamps the material box, the spring force of the torsion spring causes the connecting rod to rotate towards the top of the material box, thereby pressing the pressure plate firmly against the top of the material box. The linkage assembly includes a connecting rod and a pivot shaft connected to one end of the connecting rod. The other end of the connecting rod is rotatably connected to the pressure plate. This design allows the pressure plate to move flexibly within a certain range. Furthermore, the torsion spring is disposed on the pivot shaft. In the clamped position, the spring force provided by the torsion spring causes the connecting rod to rotate towards the top of the material box. This tendency ensures that the pressure plate can continuously apply pressure, firmly pressing the top of the material box.

[0019] In some embodiments, multiple connecting rods and rotating shafts are used, with each rotating shaft connected to two connecting rods at each end. These multiple connecting rods and rotating shafts are configured to work collaboratively, with each rotating shaft connected to two connecting rods at each end. This design enhances system stability by distributing the forces applied to the system, making the structure more robust and maintaining good balance and performance even when handling heavy or large containers. Furthermore, the configuration of multiple connecting rods and rotating shafts ensures even force distribution, reducing localized pressure on the container and lowering the risk of damage.

[0020] In some embodiments, the clamping device further includes a second adjusting member threadedly through the top of the crossbeam and used to adjust the spring force of the torsion spring. By rotating the second adjusting member, the force applied by the torsion spring can be precisely controlled, thereby adjusting the clamping force of the clamping device.

[0021] In some embodiments, the positioning device includes a backing plate and a sensing component disposed on the backing plate. The backing plate is located on the frame and below the clamping device. The backing plate is used to abut against the side of the material box, and the sensing component is used to detect whether the material box is in close contact with the backing plate. The backing plate is fixed to the frame and located below the clamping device. Its main function is to contact the side of the material box to ensure that the material box is in the correct position. The sensing component is used to detect whether the material box is in close contact with the backing plate, thereby providing accurate positioning information. When the material box is in close contact with the backing plate, the sensing component will send a signal to confirm that the material box is in the correct position. This design not only improves the accuracy of positioning but also provides real-time feedback in automated operations, ensuring consistency and reliability of each operation. This is particularly important for applications requiring high-precision positioning, helping to reduce errors and improve the efficiency and safety of the overall system.

[0022] In some embodiments, the clamping device further includes a spring clip base connected to the frame and located below the backing plate. The spring clip base receives the material box and clamps it with the cooperating pressure plate. Its main function is to receive the material box and cooperate with the pressure plate to clamp it. This design not only provides a stable support platform for the material box but also works with the pressure plate to ensure the stability and safety of the material box during clamping. This structure helps reduce material box movement or tilting during operation, thereby improving the overall efficiency and reliability of the clamping device.

[0023] In some embodiments, the lifting device includes a drive component, a lead screw, a fixed frame, and a guide rail mounted on the frame along the height direction. The fixed frame is fixed to the support and slidably mounted on the guide rail. The drive component is mounted on the frame. One end of the lead screw is connected to the drive component, and the other end is rotatably connected to the fixed frame. The drive component drives the lead screw to rotate, thereby causing the fixed frame and the clamping device to move up and down along the guide rail. The drive component provides a power source, converting the rotational motion into linear lifting motion of the fixed frame by rotating the lead screw. The fixed frame is fixed to the support and slidably moves along the guide rail, ensuring that the entire device maintains a stable and smooth motion trajectory during lifting. This design not only improves the operational accuracy and reliability of the equipment but also enhances the flexibility of the system, enabling it to adapt to operational needs at different heights.

[0040] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0041] Please see Figures 1 to 11In some embodiments, the present invention provides a material clamping device 10, which includes a frame 100, a positioning device 200, a lifting device 300, and a clamping device 400. The lifting device 300 is disposed on the frame 100, the positioning device 200 is disposed on the frame 100 and is used to abut against the side of the material box 20 to position the material box 20, and the clamping device 400 can move up and down relative to the frame 100 under the drive of the lifting device 300. The clamping device 400 includes a bracket 410, a connecting rod assembly 420, a pressure plate 430, and an elastic element 440 connected to the lifting device 300. One end of the connecting rod assembly 420 is rotatably connected to the bracket 410, and the other end of the connecting rod assembly 420 is rotatably connected to the pressure plate 430. The elastic element 440 is connected between the pressure plate 430 and the bracket 410. When clamping the material box 20, the positioning device 200 abuts against the side of the material box 20. The clamping device 400 can be lowered under the drive of the lifting device 300, causing the pressure plate 430 to abut against the top of the material box 20. Under the force of the material box 20, the pressure plate 430 can overcome the elastic force of the elastic member 440, causing the connecting rod assembly 420 to rotate away from the material box 20. The elastic force provided by the elastic member 440 can make the pressure plate 430 tend to press down on the top of the material box 20. The clamping device 400 can also be raised under the drive of the lifting device 300 to separate the pressure plate 430 from the top of the material box 20.

[0042] The aforementioned material clamping device 10 achieves at least the following beneficial effects: The lifting device 300 and the clamping device 400 can automatically adjust the position of the pressure plate 430 to adapt to material boxes 20 of different heights, thereby eliminating the need for height screening of the material boxes 20 and improving the flexibility and efficiency of the production line. Secondly, the combined design of the connecting rod assembly 420 and the elastic element 440 allows the pressure plate 430 to reliably clamp or release the material box 20. The elastic force provided by the elastic element 440 ensures that the pressure plate 430 can stably apply pressure to the top of the material box 20, maintaining reliable clamping performance even when facing various material boxes 20 of inconsistent heights, significantly improving operational safety and stability. For example, as... Figure 8 As shown, the clamping device 400 can first pre-press the material box 20, so that the pressure plate 430 first slightly abuts against the top of the material box 20, and then... Figure 9The lifting device 300 can be further lowered for fine-tuning, further increasing the elastic force of the elastic element 440, thereby increasing the downward pressure of the pressure plate 430 on the material box 20, reaching the clamping position to achieve the purpose of clamping the material box 20. This universal design not only reduces the manufacturing and maintenance costs of the equipment, but also avoids the need to design special clamping mechanisms for material boxes 20 of different heights. It effectively solves the problems of low efficiency, high cost and lack of flexibility in traditional technologies, providing a high-efficiency, economical and reliable solution for the production line.

[0043] Specifically, such as Figures 4 to 7 As shown, in some embodiments, the support 410 includes a vertical frame 411 connected to the lifting device 300 and a horizontal beam 412 connected to the vertical frame 411. One end of the linkage assembly 420 is rotatably connected to the end of the horizontal beam 412 away from the vertical frame 411, and the other end of the linkage assembly 420 is rotatably connected to the pressure plate 430, which is located below the horizontal beam 412. The elastic element 440 includes a tension spring 441, the first end of which is fixed to the vertical frame 411, and the second end of which is fixed to the pressure plate 430. When the pressure plate 430 clamps the material box 20, the first end is lower than the second end in the height direction and the tension spring 441 is in a stretched state, so that the tension of the tension spring 441 can make the pressure plate 430 have a tendency to press down on the top of the material box 20. The elastic element 440 uses a tension spring 441, with its first end fixed to the upright 411 and its second end fixed to the pressure plate 430. This configuration ensures that when the pressure plate 430 clamps the material box 20, the first end of the tension spring 441 is lower than the second end in the height direction and is in a stretched state, thus providing a downward pulling force. This pulling force allows the pressure plate 430 to tend to press down on the top of the material box 20 when it abuts against it, ensuring a stable and reliable clamping effect even when handling material boxes 20 with inconsistent heights. The overall design not only improves the operating efficiency and safety of the equipment but also further enhances the flexibility and adaptability of the production line by reducing the need for height screening.

[0044] Specifically, such as Figure 6 and Figure 7As shown, in some embodiments, the pressure plate 430 includes a first pressure plate 431 rotatably connected to one end of the connecting rod assembly 420 and a second pressure plate 432 stacked on top of the first pressure plate 431. The top of the first pressure plate 431 is fixed to the first end of the tension spring 441. The second pressure plate 432 is located on the side of the first pressure plate 431 facing away from the crossbeam 412 and is a flexible plate. The top of the first pressure plate 431 is fixed to the first end of the tension spring 441, enabling it to effectively transmit the tension of the tension spring 441 and ensuring that the second pressure plate 432 connected to the first pressure plate 431 has sufficient downward pressure when clamping the material box 20. The second pressure plate 432 is located on the side of the first pressure plate 431 facing away from the crossbeam 412 and is made of a flexible material (such as urethane). It can effectively absorb and alleviate pressure fluctuations during clamping, protect the material box 20 from damage caused by excessive pressure, and improve the stability and safety of clamping.

[0045] Specifically, such as Figure 7 As shown, in some embodiments, the end of the crossbeam 412 away from the upright 411 extends downward to form a bent portion 413, the pressure plate 430 is located on the side of the bent portion 413 facing the upright 411, and the first end of the tension spring 441 is fixed to the bent portion 413. The crossbeam 412 is designed to extend downward to form a bent portion 413 at the end away from the upright 411, and the first end of the tension spring 441 is fixed to the bent portion 413. This connection method ensures that the tension spring 441 can effectively apply tension, giving the pressure plate 430 sufficient downward pressure to achieve a stable clamping effect.

[0046] Specifically, such as Figures 4 to 7As shown, in some embodiments, the clamping device 400 includes a first adjusting member 451, which is threadedly rotatably inserted into the bending portion 413. One end of the first adjusting member 451 abuts against the pressure plate 430, and the other end is operated to adjust the tension of the tension spring 441. When the pressure plate 430 clamps the material box 20, the pressure plate 430 can move away from the first adjusting member 451 under the pressure of the top of the material box 20, further stretching the tension spring 441. The first adjusting member 451 is threadedly inserted into the bending portion 413, allowing its position to be flexibly adjusted. One end of the first adjusting member 451 abuts against the pressure plate 430, a design that allows the user to operate through the other end of the first adjusting member 451 to adjust the tension of the tension spring 441. In the clamped position, when the pressure plate 430 is compressed from the top of the cassette 20, the pressure plate 430 can move away from the first adjusting member 451. This movement further stretches the tension spring 441, thereby increasing the system's elasticity and the clamping force on the cassette 20. This design not only provides precise control over the clamping force but also allows for rapid adjustment of the tension of the tension spring 441 under different operating conditions to accommodate cassettes 20 of different sizes.

[0047] Specifically, such as Figure 6 As shown, in some embodiments, the linkage assembly 420 includes a connecting rod 421 and a rotating shaft 422 connected to one end of the connecting rod 421. The other end of the connecting rod 421 is rotatably connected to the pressure plate 430. The rotating shaft 422 is rotatably mounted through the crossbeam 412. The elastic element 440 also includes a torsion spring 442, which is disposed on the rotating shaft 422. When the pressure plate 430 clamps the material box 20, the elastic force of the torsion spring 442 causes the connecting rod 421 to have a tendency to rotate towards the top of the material box 20, so that the pressure plate 430 presses against the top of the material box 20. The linkage assembly 420 includes a connecting rod 421 and a rotating shaft 422 connected to one end of the connecting rod 421. The other end of the connecting rod 421 is rotatably connected to the pressure plate 430. This design allows the pressure plate 430 to move flexibly within a certain range. In addition, a torsion spring 442 is provided on the rotating shaft 422. When in the clamping position, the elastic force provided by the torsion spring 442 causes the connecting rod 421 to tend to rotate toward the top of the material box 20. This tendency ensures that the pressure plate 430 can continuously apply pressure to firmly press the top of the material box 20.

[0048] Specifically, such as Figure 4As shown, in some embodiments, the number of connecting rods 421 and rotating shafts 422 is set to multiple, with each rotating shaft 422 connected to two connecting rods 421 at each end. The multiple connecting rods 421 and rotating shafts 422 are configured to work collaboratively, with each rotating shaft 422 connected to two connecting rods 421 at each end. This design enhances system stability by distributing the forces applied to the system, making the structure more robust and maintaining good balance and performance even when handling heavier or larger material boxes 20. Furthermore, the configuration of multiple connecting rods 421 and rotating shafts 422 ensures uniform force distribution, reducing localized pressure on the material box 20 and lowering the risk of damage.

[0049] Specifically, such as Figure 4 As shown, in some embodiments, the clamping device 400 further includes a second adjusting member 452, which is threadedly rotatably threaded through the top of the crossbeam 412. The second adjusting member 452 is used to adjust the spring force of the torsion spring 442. By rotating the second adjusting member 452, the force applied by the torsion spring 442 can be precisely controlled, thereby adjusting the clamping force of the clamping device 400.

[0050] Specifically, such as Figure 12 and Figure 13 As shown, in some embodiments, the positioning device 200 includes a backing plate 210 and a sensing component disposed on the backing plate 210. The backing plate 210 is disposed on the frame 100 and located below the clamping device 400. The backing plate 210 is used to abut against the side of the material box 20, and the sensing component is used to detect whether the material box 20 is in close contact with the backing plate 210. The backing plate 210 is fixed on the frame 100 and located below the clamping device 400. Its main function is to contact the side of the material box 20 to ensure that the material box 20 is in the correct position. The sensing component is used to detect whether the material box 20 is in close contact with the backing plate 210, thereby providing accurate positioning information. When the material box 20 is in close contact with the backing plate 210, the sensing component will send a signal to confirm that the material box 20 is in the correct position. This design not only improves the accuracy of positioning but also provides real-time feedback in automated operation, ensuring consistency and reliability of each operation. This is especially important for applications requiring high-precision positioning, as it helps reduce errors and improve the overall system efficiency and security.

[0051] Specifically, in some embodiments, the sensing assembly includes at least one of a sensor 221, a photoelectric switch 222, a sensing block 223, and a hinge pin 224. The sensor 221 can be used to detect the position or state of the material box 20, and can be contact or non-contact, providing precise positioning information. The photoelectric switch 222 can utilize photoelectric principles for detection, typically used to detect the presence or positional changes of objects, and features fast response and high accuracy. By combining these components, the sensing assembly can flexibly adapt to different detection needs, improving the detection accuracy and reliability of the system. This diverse design enables the device to maintain efficient operation in various complex application environments.

[0052] Specifically, such as Figure 3 As shown, in some embodiments, the clamping device 10 further includes a spring clip base 500, which is connected to the frame 100 and located below the backing plate 210. The spring clip base 500 is used to support the material box 20 and clamp the material box 20 in conjunction with the pressure plate 430. The spring clip base 500 is connected to the frame 100 and located below the backing plate 210. Its main function is to support the material box 20 and cooperate with the pressure plate 430 to clamp the material box 20. Through this design, the spring clip base 500 not only provides a stable support platform for the material box 20, but also works with the pressure plate 430 to ensure the stability and safety of the material box 20 during clamping. This structure helps to reduce the movement or tilting of the material box 20 during operation, thereby improving the overall efficiency and reliability of the clamping device.

[0053] Specifically, such as Figure 3 As shown, in some embodiments, the lifting device 300 includes a drive member 310, a lead screw 320, a fixed frame 330, and a guide rail 340 arranged along the height direction on the frame 100. The fixed frame 330 is fixed to the support 410 and slidably disposed on the guide rail 340. The drive member 310 is disposed on the frame 100. One end of the lead screw 320 is connected to the drive member 310, and the other end of the lead screw 320 is rotatably connected to the fixed frame 330. The drive member 310 drives the lead screw 320 to rotate, thereby driving the fixed frame 330 and the clamping device 400 to move up and down along the guide rail 340. The drive member 310 provides a power source, converting the rotational motion of the lead screw 320 into the linear lifting motion of the fixed frame 330. The fixed frame 330 is fixed to the support 410 and slidably moves along the guide rail 340, ensuring that the entire device maintains a stable and smooth motion trajectory during the lifting process. This design not only improves the operational accuracy and reliability of the equipment, but also enhances the system's flexibility, enabling it to adapt to operational needs at different heights.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0057] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0058] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0059] In this utility model, unless otherwise explicitly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0060] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this invention are for illustrative purposes only and do not represent the only possible implementation.

[0061] In this specification, the use of terms such as "an embodiment," "another implementation," etc., refers to a specific feature, structure, material, or characteristic described in connection with that embodiment or example that is included in at least one embodiment or example of the present invention. In this specification, the illustrative descriptions of the above terms do not necessarily refer to the same embodiment or example. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
