Description

Technical Field

[0001] This invention relates to the field of battery pack recycling equipment technology, and in particular to a flexible intelligent disassembly device for battery packs. Background Technology

[0002] A battery pack typically consists of a battery body and a battery rim located in the middle of the side of the battery body. The battery body is rectangular in shape. To achieve efficient recycling of the battery pack, it is usually necessary to cut open the battery rim (which is typically used to secure the outer casing) completely before removing the internal components of the battery pack.

[0003] Traditional laser cutting of battery packs typically involves placing the battery pack on a worktable and then using a laser cutting device to irradiate and cut the battery edges. However, the battery pack's orientation is uncertain when it arrives at the cutting station. Vibration or differential speed during transport can alter its orientation, causing horizontal deflection and displacement upon arrival. To flexibly adapt to different battery pack orientations, current technology uses 3D scanning to acquire the pack's orientation and then plans a scanning path accordingly. However, this requires a 3D scanner and a complex software control system. Solving the flexibility issue through mechanical structures could significantly reduce equipment costs. Furthermore, in traditional laser cutting, the laser may penetrate the battery edges and damage the worktable. Additionally, to minimize worktable damage, the power of the laser cutting device is limited, affecting efficiency. Summary of the Invention

[0004] One object of the present invention is to solve or alleviate the above-mentioned technical problems.

[0005] The present invention employs a flexible intelligent disassembly device for battery packs. The battery pack includes a battery body and a battery edge located in the middle of the side of the battery body. The battery body is rectangular. The flexible intelligent disassembly device is used to cut the battery edge. The device includes a laser cutting device and a lifting platform with lifting power. It also includes a clearance component and four sets of side abutment components. Adjacent sets of side abutment components are arranged perpendicularly to each other and arranged opposite each other in pairs. Each set of side abutment components includes at least one side abutment device. The side abutment device includes a side abutment member, a clearance abutment member, a clearance sliding member, and a clearance elastic member. The device includes a movable carrier with lateral linear force; a slidable member is linearly connected to the movable carrier along the direction of the lateral linear force of the movable carrier; a slidable elastic member is connected to the slidable member and the movable carrier respectively, so that the slidable member tends to move towards the side abutment; the side abutment is directly or indirectly disposed on the slidable member, and the slidable abutment is disposed on the side abutment and fixed relative to the side abutment; the slidable assembly includes a slidable abutment connected to the laser cutting device, and the slidable abutment is provided with abutment slope; as the slidable abutment moves with the laser cutting device, the slidable abutment can abut against the abutment slope, so that the side abutment moves away from the battery body.

[0006] The present invention achieves the following effect: by using four sets of side abutment components to align and correct the battery pack, the device can adapt to battery packs of different postures and achieve flexibility; at the same time, it can perform circumferential cutting on the battery edge while the battery pack is suspended in the air, and can avoid or reduce damage to the device caused by the laser cutting device.

[0007] A further technical solution includes a side abutment member comprising a side abutment wheel frame and a side abutment wheel. The side abutment wheel frame is provided with a wheel hinge portion, and the side abutment wheel is hinged to the wheel hinge portion with the hinge axis being vertical. The side abutment wheel is provided with a battery edge gap for accommodating the battery edge. The movable carrier of the four sets of side abutment components is connected to a linear power device.

[0008] This technical solution can ensure the effectiveness of battery pack location determination; it can also simplify the structure and improve efficiency.

[0009] A further technical solution is to fix the yielding component to the top of the side abutment wheel frame; the yielding assembly also includes a yielding abutment frame fixedly connected to the laser cutting device, the yielding abutment frame including mounting parts evenly distributed around the axis of the laser cutting device, and the yielding abutment components are respectively slidably connected to the mounting parts in a vertical direction.

[0010] This technical solution simplifies the equipment structure and helps reduce costs.

[0011] A further technical solution includes a rising elastic element and four lower pressure rails. The four lower pressure rails are respectively set above the four sets of side abutment components, and the lower pressure rails are provided with a downward tilting section. The two ends of the rising elastic element are respectively connected to the yielding abutment and the mounting part, so that the yielding abutment has an upward trend. The four yielding abutment can be abutted by the four downward tilting sections and lowered.

[0012] This technical solution simplifies the equipment structure, which helps reduce costs and improve reliability.

[0013] A further technical solution is that the top of the relief support member is provided with a rising elastic element edge, the rising elastic element is a spring and is sleeved on the relief support member, and the two ends of the rising elastic element abut against the rising elastic element edge and the mounting part, respectively.

[0014] A further technical solution includes a swing seat for the side abutment device. The side abutment wheel frame is rotatably connected to the relief slider through the swing seat, so that the side abutment wheel frame can rotate relative to the relief slider in the horizontal plane. There are two side abutment wheels on the side abutment wheel frame, and the two side abutment wheels are symmetrical about the swing seat.

[0015] This technical solution enables the side-bracing wheels to generate a larger clearance and improve reliability.

[0016] A further technical solution includes two swinging elastic elements in the side abutment device; the two ends of the swinging elastic elements are respectively connected to the side abutment wheel frame and the yielding sliding element, and the two swinging elastic elements are symmetrical about the swing seat.

[0017] This technical solution ensures that the side abutment wheel frame automatically resets.

[0018] A further technical solution involves using a oscillating elastic element to provide repulsive force.

[0019] This technical solution allows the side-bracing wheels to have a larger clearance and improves reliability.

[0020] A further technical solution involves a swing elastic element that is a spring, a side-supporting wheel frame that is fixedly equipped with an anti-detachment rod, and the other end of the anti-detachment rod passing through a clearance sliding element; the swing elastic element is fitted onto the anti-detachment rod.

[0021] This technical solution can prevent the oscillating elastic element of the spring from falling off and improve the reliability of the equipment.

[0022] A further technical solution involves threading two swing adjustment components onto the sliding member; the two swing adjustment components are symmetrical about the swing seat and one end of each component can abut against the side abutment wheel frame.

[0023] This technical solution can easily adjust and limit the maximum rotation angle of the side abutment wheel frame, preventing the side abutment wheel frame from rotating excessively. Attached Figure Description

Detailed Implementation

[0039] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0040] As a specific embodiment, the battery pack flexible intelligent disassembly device of the present invention, such as... Figure 3 As shown, the battery pack (i.e., battery pack 9) includes a battery body 91 and a battery edge 92 located in the middle of the side of the battery body 91. The battery body 91 is rectangular. The battery pack flexible intelligent disassembly device is used to cut the battery edge 92. The battery edge 92 is actually a double edge formed by connecting the upper outer shell and the lower outer shell of the battery pack 9 together. After the battery edge 92 is cut, the upper outer shell and the lower outer shell can be easily separated. After lifting the upper outer shell, it is convenient to process the internal components of the battery pack 9.

[0041] The battery pack flexible intelligent disassembly equipment of the present invention includes a laser cutting device 1 and a lifting platform 2 with lifting power.

[0042] The laser cutting device 1 is existing technology, which emits a laser to achieve cutting after being powered on; for ease of understanding and expression, the specific shape and other details of the laser cutting device 1 are not shown in detail in the accompanying drawings.

[0043] The lifting platform 2 is used to temporarily support the battery pack 9. The lifting platform 2 is equipped with lifting power by a power device of the prior art such as a cylinder (not shown in the attached figure), and is usually provided with universal ball bearings 21, which makes it easier to move the battery pack 9 on the lifting platform 2.

[0044] The battery pack flexible intelligent disassembly device of the present invention further includes a clearance component 4 and four sets of side abutment components.

[0045] The four sets of side abutment components are arranged perpendicularly to each other and opposite to each other in pairs. It is easy to understand that each set of side abutment components includes at least one side abutment holding device 3. Specifically, as shown... Figure 1 As shown, the side abutment devices 3 of the left-hand side abutment assembly (a total of seven side abutment devices 3) are all aligned with the side abutment devices 3 of the right-hand side abutment assembly (a total of seven side abutment devices 3) in the left-right direction, so that the left and right sides of the side abutment assembly are arranged opposite each other; similarly, the upper and lower sides of the side abutment assembly (each with three side abutment devices 3) are arranged opposite each other. It is easy to understand that the four sides of the side abutment assembly together form a rectangular area when viewed from above, and this rectangular area can accommodate the cuboid battery body 91.

[0046] The side-supporting device 3 includes a side-supporting member 31, a yielding and supported member 32, a yielding and sliding member 33, a yielding and elastic member 35, and a movable carrier 34 with lateral linear power.

[0047] like Figures 10 to 12 As shown, arrow 1 ARR1 indicates the direction of movement of the laser cutting device 1 and the clearance component 4; arrow 2 ARR2 indicates the direction in which the clearance support member 41 is lowered by the lowering tilt section 441. Multiple movable carriers 34 are respectively fixed on the main mounting plate 348, which is given lateral linear power by linear power devices 349 such as cylinders and electric cylinders.

[0048] It should be noted that the movable carrier 34 possesses lateral linear power, meaning that the movable carrier 34 is relative to the side-supporting device 3 opposite to it. For example, referring to... Figure 12 As shown, if the side abutment components on the left side are fixed, only the side abutment components on the right side can move left and right through the linear power device 349; then the side abutment components on the right side can move left and right relative to the side abutment components on the left side, and also have lateral linear power; the side abutment holding devices 3 on the upper and lower sides are similar.

[0049] The sliding member 33 and the movable carrier 34 are linearly connected along the direction of the lateral linear force of the movable carrier 34. For example, the sliding member 33 and the movable carrier 34 are linearly connected through a linear guide device 339 such as a linear bearing. Figure 11 As shown, the sliding member 33 of the side abutment device 3 on the left side is linearly slidably connected to the movable carrier 34 and can slide left and right. The movable carrier 34 has lateral linear power in the left and right directions.

[0050] The yielding elastic member 35 is connected to both the yielding sliding member 33 and the movable carrier 34, causing the yielding sliding member 33 to tend to move towards the lateral abutment member 31. For example, as Figures 7 to 9As shown, the yielding elastic member 35 is a spring and is sleeved on the linear guide device 339. The two ends of the yielding elastic member 35 abut against the fixed end of the linear guide device 339 and the abutment block protruding from the movable carrier 34 respectively to provide repulsive force, so that the yielding sliding member 33 has a tendency to move closer to the side abutment member 31.

[0051] like Figure 9 As shown, the side abutment 31 is directly or indirectly disposed on the yielding slide member 33, and the yielding resisted member 32 is disposed on the side abutment 31 and fixed relative to the side abutment 31. For example (not shown in the accompanying drawings of this embodiment), the side abutment 31 is fixed on the yielding slide member 33, and the yielding resisted member 32 is fixed on the side abutment 31, such that the side abutment 31 is directly disposed on the yielding slide member 33, and the yielding resisted member 32 is fixed relative to the side abutment 31. Of course, the side abutment 31 can also be indirectly disposed on the yielding slide member 33 through a swing seat 372 or the like described later. The side abutment 31 can be an object with a certain elasticity, such as a rubber block, or it can be the structure described later.

[0052] The yielding component 4 includes a yielding support member 41 connected to the laser cutting device 1, and a yielding support member 32 is provided with a support slope 321.

[0053] As the laser cutting device 1 moves, the yielding support 41 can abut against the inclined surface 321, thereby moving the side support 31 away from the battery body 91.

[0054] The working principle is as follows: Figure 12 As shown in the figure, arrow ARR1 indicates the moving direction and path of the laser cutting device 1 and the clearance component 4. Before cutting, the battery pack is aligned and corrected by four sets of side abutment components, so that battery packs in different postures are adjusted to the ideal posture, so that all cutting is carried out along a preset route, achieving the purpose of flexibly adapting to different battery postures. In order to cut the entire battery edge 92 to achieve circumferential cutting (the circumferential cutting in the flexible intelligent disassembly device for battery packs), the running trajectory of the laser cutting device 1 is roughly a rectangular ring in a horizontal plane. It is easy to understand that the rectangular ring running trajectory of the laser cutting device 1 can be achieved by using a multi-axis manipulator or a three-way sliding module (not shown in the figure), or by using a rectangular ring guide rail structure in conjunction with a linear power device.

[0055] Before use, place the battery pack 9 on the lifting platform 2. The lifting platform 2 then raises the battery pack 9 so that the side of the battery body 91 faces the side abutment 31. The movable carrier 34 then moves laterally towards the battery body 91, so that the side abutments 31 abut against the four sides of the battery body 91. The position of the battery body 91 on the horizontal plane is determined, and the battery body 91 is adjusted to a standard posture. Then, the lifting platform 2 descends, and the friction between the battery body 91 and the side abutments 31 keeps the battery pack 9 suspended in the air.

[0056] The laser cutting device 1 is activated and moved along a rectangular circular trajectory to cut the battery edge 92. During this process, since the battery pack 9 remains suspended, the laser passing through the battery edge 92 does not affect the support platform or other structures below the battery pack 9.

[0057] As the laser cutting device 1 moves along a rectangular circular trajectory, the clearance support 41 moves along with the laser cutting device 1. For example... Figure 14 As shown, arrow ARR1 indicates the moving direction of the laser cutting device 1 and the clearance component 4; arrow ARR4 indicates the direction in which the clearance support member 41 abuts against the inclined surface 321, causing the side support member 31 and the clearance sliding member 33 to move. When the laser cutting device 1 reaches the corresponding side support member 31, the clearance support member 41 abuts against the inclined surface 321, causing the corresponding side support member 31 to move away from the side wall of the battery body 91, forming a gap between the side support member 31 and the side wall of the battery body 91. The rectangular annular trajectory of the laser cutting device 1 passes through this gap, ensuring that the laser cutting device 1 does not act on the side support member 31. When the laser cutting device 1 moves to a point where it is completely displaced from the corresponding side support member 31, the corresponding side support member 31 resets and continues to abut against the side of the battery body 91. This process continues until the laser cutting device 1 completes the entire rectangular annular trajectory (for...). Figure 12 (In the clockwise direction shown), a sealed rectangular annular cut is formed on the battery edge 92, completely separating the outer ring of the battery edge 92 from the inner ring. The battery pack 9 is then cut and the upper casing can be lifted. Of course, after the sealed rectangular annular cut is completed, the battery pack 9 remains suspended and will not fall off due to the friction between the battery body 91 and the side support 31.

[0058] Then, after the lifting platform 2 rises to support the battery pack 9, each set of side-supporting components moves laterally away from the battery pack 9. After the battery pack 9 falls onto the lifting platform 2, the lifting platform 2 descends. Afterward, the cut battery pack 9 can be transported to the next process via a conveyor trolley, transport rail, or other means.

[0059] As can be seen from the above, the flexible intelligent disassembly device for battery packs of the present invention can perform circumferential cutting on the battery edge 92 while the battery pack 9 is suspended in the air, while avoiding or reducing damage to the device by the laser cutting device 1.

[0060] As one of the specific implementation methods, such as Figure 7 As shown, the side abutment member 31 includes a side abutment wheel frame 37 and a side abutment wheel 36. The side abutment wheel frame 37 is provided with a wheel hinge portion 371, and the side abutment wheel 36 is hinged to the wheel hinge portion 371 with the hinge axis in the vertical direction. It is easy to understand that the side abutment wheel 36 can still suspend the battery pack 9 in the air by friction when abutting against the side of the battery body 91, but the side abutment wheel 36 can roll relative to the side of the battery body 91 in the horizontal plane. The side abutment wheel 36 is provided with a battery edge gap 361 for accommodating the battery edge 92. The movable carriers 34 of the four sets of side abutment components are connected to a linear power device 349. It is easy to understand that the movable carriers 34 of the four sets of side abutment components can all move. The side abutment wheels 36 can abut against the sides of the battery body 91 above and below the battery edge 92 (that is, abut against the upper and lower housings of the battery edge 92 respectively), ensuring the positioning effect of the battery pack 9; in addition, after the battery edge 92 of the battery pack 9 is cut, the outer ring of the battery edge 92 is completely separated from the inner ring of the battery edge 92; after all four sets of side abutment components are moved away from the battery pack 9, the outer ring of the battery edge 92 is pulled out from the battery edge gap 361 of all four sets of side abutment components. Due to the obstruction of the inner ring of the battery edge 92, the battery edge 92... Even if the outer ring of battery rim 92 falls onto the lifting platform 2 due to its own weight, it is still confined to the position of being fitted onto the battery body 91. This facilitates the handling of the battery pack 9 after the lifting platform 2 descends, which is beneficial to improving efficiency. Compared to the fixed movable carrier 34 among the four sets of side abutment components (which requires moving the battery pack 9 to allow the outer ring of battery rim 92 to be pulled out from the battery rim gap 361), there is no need to set up a device to move the battery body 91 so that the outer ring of battery rim 92 can be pulled out from the battery rim gap 361, which simplifies the structure and improves efficiency.

[0061] As one specific implementation, the yielding abutment 32 is fixed to the top of the side abutment wheel frame 37; the yielding assembly 4 also includes a yielding abutment frame 42 fixedly connected to the laser cutting device 1. The yielding abutment frame 42 includes mounting portions 421 evenly distributed around the axis of the laser cutting device 1. The yielding abutment 41 is linearly slidably connected to the mounting portions 421 in the vertical direction. For example, the yielding abutment 41 fits snugly through the mounting portions 421 to achieve a linearly slidable connection in the vertical direction. This is easily understood, such as... Figure 6 As shown, the central angle between two adjacent mounting parts 421 is ninety degrees; therefore, as Figure 12As shown, the four yielding abutment members 41 correspond to the yielding abutment members 32 of the four sets of side abutment components. During the operation of the laser cutting device 1 along a rectangular circular trajectory, one of the four yielding abutment members 41 descends and abuts against the yielding abutment member 32 of its corresponding set of side abutment components. The other three yielding abutment members 41 are in an elevated state to avoid the battery pack 9 (the timing of the descent and ascent of the four yielding abutment members 41 can be controlled by a cylinder and an electronic control device that controls the cylinder's lifting and lowering, or automatically through a method described later). For example... Figure 12 As shown, the lowermost yielding abutment member 41 descends to abut against the yielding abutment member 32 of the lower side abutment component, thus avoiding the laser cutting device 1. The three yielding abutment members 41 on the left, top, and right rise to avoid the battery pack 9. When the laser cutting device 1 moves upward, the leftmost yielding abutment member 41 descends to abut against the yielding abutment member 32 of the leftmost side abutment component, while the three yielding abutment members 41 on the bottom, top, and right rise to avoid the battery pack 9; and so on. In the above process, the laser cutting device 1 does not need to rotate around itself. For the laser cutting device 1 that moves by the aforementioned multi-axis manipulator, the operation program of the multi-axis manipulator can be set relatively easily. For the laser cutting device 1 that moves by the aforementioned rectangular ring guide structure in conjunction with a linear power device, the rectangular ring guide structure and the corresponding linear power device can also be set relatively easily. In summary, this embodiment simplifies the equipment structure and helps to reduce costs.

[0062] As one specific implementation, the yielding assembly 4 also includes a rising elastic member 43 and four lowering rails 44. The four lowering rails 44 are respectively disposed above the four sets of side abutment assemblies, and each lowering rail 44 is provided with a descending inclined section 441. The two ends of the rising elastic member 43 are respectively connected to the yielding abutment member 41 and the mounting part 421, so that the yielding abutment member 41 has an upward tendency. The four yielding abutment members 41 can be lowered by being abutted by the four descending inclined sections 441 respectively. It is easy to understand that when the yielding abutment member 41 moves to be misaligned with the lowering rail 44, the yielding abutment member 41 rises due to the elastic force of the rising elastic member 43. This implementation can control the timing of the rise and fall of the four yielding abutment members 41 separately without the need for cylinders and electronic control devices, which simplifies the equipment structure and helps to reduce costs and improve reliability.

[0063] As one specific implementation, the top end of the relief support member 41 is provided with a rising elastic edge 431. The rising elastic element 43 is a spring and is sleeved on the relief support member 41. The two ends of the rising elastic element 43 abut against the rising elastic edge 431 and the mounting part 421 respectively, so that the relief support member 41 has an upward tendency.

[0064] As one of the specific implementation methods, such as Figure 9 As shown, line LINE1 represents the rotation axis passing through the swing seat 372 and parallel to the direction of the linear guide device 339. The side abutment device 3 also includes the swing seat 372, and the side abutment wheel frame 37 is rotatably connected to the relief slider 33 through the swing seat 372, so that the side abutment wheel frame 37 can rotate relative to the relief slider 33 in the horizontal plane (i.e., the hinge axis of the swing seat 372 is vertical). There are two side abutment wheels 36 on the side abutment wheel frame 37, and the two side abutment wheels 36 are symmetrical about the swing seat 372. Figure 14 As shown, arrow 1 ARR1 indicates the direction of movement of the laser cutting device 1 and the clearance component 4; arrow 4 ARR4 indicates the direction in which the clearance support member 41 abuts against the inclined surface 321, causing the side support member 31 and the clearance sliding member 33 to move; arrow 5 ARR5 indicates the direction in which the clearance support member 41 abuts against the inclined surface 321, causing the side support wheel frame 37 and the clearance support member 32 to swing. While the yielding abutment member 41 abuts against the inclined surface 321, causing the yielding slider 33 to move along arrow four (ARR4), the yielding abutment member 41 abuts against the inclined surface 321, and also causes one of the two side abutment wheels 36, the one closer to the yielding abutment member 41, to swing around the contact point between the other side abutment wheel 36 (the one farther away from the yielding abutment member 41) and the side of the battery body 91. This causes the side abutment wheel 36 to avoid the laser cutting device 1. During this process, while the yielding slider 33 slides in a straight line to avoid the laser cutting device 1, the side abutment wheel 36 also rotates along arrow five (ARR5). Figure 14 The clockwise rotation (as shown) allows for clearance, enabling one of the side abutment wheels 36 to have a larger clearance space. As the clearance abutment member 41 continues to move with the laser cutting device 1 past the swing elastic member 373, the other side abutment wheel 36 rotates (in the clockwise direction shown) to achieve clearance, allowing the one side abutment wheel 36 to generate a larger clearance space. Figure 14 The counter-clockwise direction shown also allows for a larger clearance space for the other side abutment wheel 36. This principle applies to the other side abutment devices 3 as well. In summary, this embodiment allows for a larger clearance space for the side abutment wheel 36, improving reliability.

[0065] As one specific implementation, the side-holding device 3 further includes two swinging elastic members 373; the two ends of the swinging elastic members 373 are respectively connected to the side-holding wheel frame 37 and the relief sliding member 33, and the two swinging elastic members 373 are symmetrical about the swing seat 372. The swinging elastic members 373 provide tensile or repulsive forces. The elastic force provided by the two swinging elastic members 373 can ensure that the side-holding wheel frame 37 automatically returns to its original position.

[0066] As one specific implementation, the swing elastic element 373 provides a repulsive force. When the yielding support member 41 abuts against the yielding supported member 32, the swing elastic element 373 near the yielding support member 41 is further compressed, and the compression of the swing elastic element 373 away from the yielding support member 41 is released. Compared with the swing elastic element 373 providing a tensile force (the tensile force of the swing elastic element 373 near the yielding support member 41 is reduced, and the swing elastic element 373 away from the yielding support member 41 is further stretched), the swing elastic element 373 can provide a larger supporting force to the yielding sliding member 33, so that the yielding sliding member 33 compresses the yielding elastic element 35 more (when the swing elastic element 373 provides repulsive force and tensile force, the rotation angle of the side abutting wheel frame 37 is basically the same), thereby enabling the side abutting wheel 36 to generate a larger clearance space and improve reliability. In addition, the two parts of the swing seat 372 are usually hinged by a snap ring and a pin. When installing the swing elastic element 373 (such as a spring) that provides repulsive force, during assembly, the sliding element 33 is first moved closer to the side abutting wheel frame 37 to compress the swing elastic element 373, and then the pin and snap ring of the swing seat 372 are installed. The assembly of the side abutting device 3 is also relatively simple.

[0067] In one specific implementation, the swing elastic element 373 is a spring, and an anti-detachment rod 375 is fixedly mounted on the side-supporting wheel frame 37. The other end of the anti-detachment rod 375 passes through the relief sliding element 33; the swing elastic element 373 is sleeved on the anti-detachment rod 375. It is easy to understand that the relief sliding element 33 has a through hole for the other end of the anti-detachment rod 375 to pass through. This implementation can prevent the spring-type swing elastic element 373 from falling off, improving equipment reliability.

[0068] As one specific implementation, two swing adjustment members 374 are threadedly connected to the sliding member 33; the two swing adjustment members 374 are symmetrical about the swing seat 372 and one end of each can abut against the side abutment wheel frame 37. Rotating the swing adjustment member 374 can easily adjust and limit the maximum rotation angle of the side abutment wheel frame 37, preventing the side abutment wheel frame 37 from rotating excessively.

[0069] The terms used in this invention, such as "first," "second," etc., do not indicate any order, quantity, or importance, but are merely for distinction.

[0070] In this invention, terms such as "a," "an," etc., do not indicate a limitation on the quantity, but rather indicate the existence of at least one of the mentioned objects.

[0071] In this invention, terms indicating orientation or location such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, below, etc., are used to indicate relative positions rather than absolute positions.

[0072] Terms used in this invention, such as "approximately," "generally," "approximately," and "similar," are limiting terms used to indicate features that are present but allow for certain deviations. The amount of deviation allowed may vary depending on the specific context; for example, for deviations in dimensions, the specific context may include, but is not limited to, relevant standards for dimensional tolerances.
