Description

Technical Field

[0001] This invention relates to the field of material transportation technology, and in particular to a material picking and transferring device and a material transfer system. Background Technology

[0002] During the production process, some materials are transported by stacking and alternating layers of materials and partitions. For example, iron products like cylinders require stacking in crates during transport, with multiple layers of cylinders stacked inside the crates, each layer separated by partitions. During material handling, frequent bending and picking up of materials is necessary, which not only wastes labor and increases transportation costs, but also results in a heavy workload for workers, increasing the risk of accidents after prolonged periods of labor.

[0003] Therefore, existing technologies use fixtures to automate the loading and unloading of materials in a frame. However, most existing fixtures can only perform one function. If different materials such as partitions and materials need to be gripped, a quick-cutting module is required between two different fixtures to achieve fixture switching. However, adding a quick-cutting module makes the material handling process more complicated, time-consuming, and increases the manufacturing cost of the fixtures.

[0004] Therefore, existing fixtures need to be improved so that a single fixture can meet the gripping requirements of different materials. Summary of the Invention

[0005] To overcome the problems existing in related technologies, one of the objectives of this invention is to provide a material picking and transferring device that can meet the picking and transferring needs of various materials, is easy to use, helps to reduce the cost of material transfer, and improves the efficiency of material transfer.

[0006] A material suction and transfer device includes a main body, a suction cup is provided at the bottom of the main body, an adsorption surface is formed at the bottom of the suction cup, and a magnetic suction device is provided in the suction cup;

[0007] The suction cup is also provided with a telescopic pin structure, which includes a driving mechanism and a pin. The driving mechanism is fixed on the suction cup, and the pin is located at the output end of the driving mechanism. The driving mechanism drives the pin to move so that the pin can protrude from the adsorption surface.

[0008] This material handling and transfer device can use both suction cups and magnetic suction to pick up items for transfer. Furthermore, during operation, a telescopic pin structure works in conjunction with the suction cups, allowing the telescopic pin structure to pick up soft materials. This transfer device has a wide range of applications, is easy to use, and can reduce the cost of transferring items while improving transfer efficiency.

[0009] In a preferred embodiment of the present invention, the suction cup includes a housing and a connecting cylinder, the connecting cylinder is disposed on the main body, the housing is disposed at the bottom of the connecting cylinder, and the housing is provided with a first mounting position for accommodating the magnetic suction device;

[0010] An air cavity is provided in the side wall of the housing, and a suction port is provided at the bottom of the air cavity. The suction port forms the adsorption surface. An air inlet channel is provided in the connecting cylinder. The air inlet channel is connected to the air cavity. An air inlet connected to the vacuum generating device is provided on the air inlet channel.

[0011] The suction cup of this application can not only pick up items, such as hard partitions, through the suction port at the bottom of the air chamber, but also provide an installation position for the magnetic suction device, making the whole device compact, occupying little space, and more convenient to use.

[0012] In a preferred embodiment of the present invention, the side wall of the housing is provided with a plurality of second mounting positions, which are evenly distributed on the housing along the circumference of the housing, and the telescopic pin structure is fixed on the second mounting positions.

[0013] In a preferred embodiment of the present invention, the driving mechanism is a needle cylinder, which is fixed on the second mounting position, and the piston rod of the needle cylinder is arranged toward the adsorption surface.

[0014] The needle is fixed on the piston rod of the needle cylinder, and the angle between the axis of the needle and the adsorption surface is 30°-45°.

[0015] Multiple telescopic pin structures allow the pins to be inserted into the items to be transported from different directions during the use of this transfer device, so that the items to be transported are subjected to force evenly and can be more firmly sucked up and transported.

[0016] In a preferred embodiment of the present invention, a sealing ring is snapped into the suction port.

[0017] The sealing ring improves the sealing performance of the suction port, allowing the suction cup to firmly pick up the items to be transferred through the suction port.

[0018] In a preferred embodiment of the present invention, the magnetic attraction device includes a mounting plate and a permanent magnet. The mounting plate is movably disposed in the first mounting position, and the permanent magnet is detachably disposed at the bottom of the mounting plate. A first buffer spring is disposed at the top of the mounting plate, one end of the first buffer spring abutting against the top of the mounting plate, and the other end of the first buffer spring being fixed in the first mounting position.

[0019] The suction device of this application can attract items to be transferred by a permanent magnet, which is convenient to use. Moreover, the permanent magnet can not pick up or release items in time, which helps to improve the transfer efficiency of items and allows items to be accurately released to the designated location.

[0020] In a preferred embodiment of the present invention, the main body includes a connecting rod, the bottom of which is fixedly connected to the connecting cylinder, and a push rod cylinder is also provided at the bottom of the connecting rod. A push rod is provided at the top of the mounting plate, and one end of the push rod passes through the connecting cylinder and is fixedly connected to the output end of the push rod cylinder.

[0021] The push rod is driven by a cylinder to move the push rod, which in turn moves the mounting plate. When the mounting plate moves upward instantaneously, the magnetic force of the permanent magnet disappears instantly, thus releasing the item.

[0022] In a preferred embodiment of the present invention, the main body further includes a buffer mechanism, which comprises a base plate, a buffer seat, and a top plate. The buffer seat is disposed between the base plate and the top plate. A guide rod is provided between the base plate and the top plate, penetrating the buffer seat. A second buffer spring is provided between the top of the buffer seat and the top plate, and the second buffer spring is sleeved on the guide rod. One end of the connecting rod is fixedly connected to the connecting cylinder, and the other end is fixedly connected to the base plate.

[0023] The buffer mechanism acts as a buffer, allowing the suction cup and magnetic device to have a certain amount of elastic displacement during use, which can prevent the suction cup and magnetic device from damaging the object to be attracted.

[0024] In a preferred embodiment of the present invention, two position sensing switches are provided between the base plate and the top plate. The two position sensing switches are arranged in parallel along the axial direction of the buffer mechanism, and the buffer seat is provided with sensing screws corresponding to the position sensing switches.

[0025] Two position sensors are used to detect the movement of the sensing screw, allowing the control system to limit the downward movement of the entire transfer device based on the movement of the sensing screw, thus preventing excessive downward pressure during operation and potential structural damage.

[0026] The second objective of this application is to provide a material transfer system, wherein the method uses the material suction and transfer device described above to transfer materials.

[0027] The beneficial effects of this invention are as follows:

[0028] This invention provides a material suction and transfer device, comprising a main body with a suction cup at its bottom. The bottom of the suction cup forms an adsorption surface, and a magnetic suction device is installed within the suction cup. The suction cup also features a telescopic pin structure, which includes a drive mechanism and a pin. The drive mechanism is fixed to a base, and the pin is located at the output end of the drive mechanism. The drive mechanism drives the pin to move, causing it to protrude beyond the adsorption surface. This device can handle the suction and transfer of various materials and is easy to use. During use, this suction and transfer device offers several methods for material suction, including using the suction cup to pick up cardboard, using the magnetic suction device to pick up metal products to be transferred, and inserting the pin into soft cardboard before suction. This application utilizes the telescopic pin structure and the suction cup in synergy, allowing the pin to be inserted into soft surfaces without deformation during suction, thus ensuring a firm grip on the soft surfaces and facilitating their transfer. This transfer device has a wide range of applications, is easy to use, reduces the cost of transferring items, and improves transfer efficiency.

[0029] This application also provides a material transfer system for transferring materials using the material suction and transfer device described above. This transfer system can transfer different items using only one transfer device, thereby reducing the transfer cost of items and improving the transfer efficiency of different items.

[0039] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0040] During the production process, some materials are transported by stacking and alternating layers of materials and partitions. For example, iron products like cylinders require stacking in crates during transport, with multiple layers of cylinders stacked inside the crates, each layer separated by partitions. During material handling, frequent bending and picking up of materials is necessary, which not only wastes labor and increases transportation costs, but also results in a heavy workload for workers, increasing the risk of accidents after prolonged periods of labor.

[0041] Therefore, existing technologies use clamps to automate the loading and unloading of materials in a frame. However, most existing clamps can only perform one function. If different materials such as partitions and materials need to be clamped, a quick-cutting module is required between two different clamps to achieve clamp switching. However, adding a quick-cutting module makes the material handling process more complicated, time-consuming, and increases the manufacturing cost of the clamps. Based on this, this application provides a material picking and transferring device.

[0042] Example 1

[0043] like Figures 1-7 As shown, this embodiment provides a material suction and transfer device, including a main body 1, a suction cup 3 is provided at the bottom of the main body 1, an adsorption surface 311 is formed at the bottom of the suction cup 3, and a magnetic suction device 5 is provided in the suction cup 3;

[0044] The suction cup 3 is also provided with a telescopic pin structure 4. The telescopic pin structure 4 includes a driving mechanism and a pin 42. The driving mechanism is fixed on the suction cup 3, and the pin 42 is located at the output end of the driving mechanism. The driving mechanism drives the pin 42 to move so that the pin 42 can protrude from the adsorption surface 311.

[0045] Specifically, in practical applications, the adsorption surface 311 is located at the bottom of the suction cup 3. The bottom of the suction cup 3 has a suction port 312, which is connected to an external vacuum generator. When the vacuum generator draws a vacuum, a negative pressure is created at the suction port 312, thus allowing the adsorption of objects. More specifically, the suction cup 3 of this application can be used to adsorb hard, plate-like objects.

[0046] The aforementioned material suction and transfer device can handle the suction and transfer of various materials and is easy to use. During operation, this device offers several methods for suctioning materials, including using the suction cup 3 to pick up cardboard, using the magnetic suction device 5 to pick up metal products to be transferred, and inserting the pin 42 into soft cardboard before using the suction cup 3 to pick it up. This application utilizes the cooperative interaction between the telescopic pin structure 4 and the suction cup 3, allowing the pin 42 to be inserted into the soft board without deformation when the suction cup 3 picks it up, thus firmly adhering to the soft board and achieving its transfer. This transfer device has a wide range of applications, is easy to use, and can reduce the cost of transferring items and improve transfer efficiency.

[0047] The material suction and transfer device of this application is particularly suitable for magnetically absorbable materials. When magnetically absorbable materials are stacked with partitions, the transfer device can be used for separation.

[0048] Example 2

[0049] like Figures 1-7 As shown, this embodiment includes the above-mentioned material suction and transfer device, including a main body 1, a suction cup 3 is provided at the bottom of the main body 1, an adsorption surface 311 is formed at the bottom of the suction cup 3, and a magnetic suction device 5 is provided in the suction cup 3.

[0050] The suction cup 3 is also provided with a telescopic pin structure 4. The telescopic pin structure 4 includes a driving mechanism and a pin 42. The driving mechanism is fixed on the suction cup 3, and the pin 42 is located at the output end of the driving mechanism. The driving mechanism drives the pin 42 to move so that the pin 42 can protrude from the adsorption surface 311.

[0051] In this embodiment, the suction cup 3 includes a housing 31 and a connecting cylinder 32. The connecting cylinder 32 is disposed on the main body 1, and the housing 31 is disposed at the bottom of the connecting cylinder 32. The housing 31 is provided with a first mounting position 313 for accommodating the magnetic suction device 5.

[0052] An air chamber 316 is provided in the side wall of the housing 31, and a suction port 312 is provided at the bottom of the air chamber 316, forming the adsorption surface 311. An air inlet channel 321 is provided in the connecting cylinder 32, which communicates with the air chamber 316. An air inlet port communicating with a vacuum generator is provided on the air inlet channel 321. The vacuum generator can supply air to the air chamber 316 or extract air from the air chamber 316 through the air inlet channel 321, so that a negative pressure is formed in the air chamber 316, thus the housing 31 can pick up items through the suction port 312.

[0053] The suction cup 3 of this application can pick up items, such as hard partitions, through the suction port 312 at the bottom of the air chamber 316; it also provides an installation position for the magnetic suction device 5, making the whole device compact, occupying little space, and more convenient to use.

[0054] This application improves the structure of the suction cup 3, so that the suction cup 3 can meet the needs of adsorbing items and also meet the installation needs of the magnetic suction device 5.

[0055] Example 3

[0056] like Figures 1-7 As shown, this embodiment includes the above-mentioned material suction and transfer device, including a main body 1, a suction cup 3 is provided at the bottom of the main body 1, an adsorption surface 311 is formed at the bottom of the suction cup 3, and a magnetic suction device 5 is provided in the suction cup 3.

[0057] The suction cup 3 is also provided with a telescopic pin structure 4. The telescopic pin structure 4 includes a driving mechanism and a pin 42. The driving mechanism is fixed on the suction cup 3, and the pin 42 is located at the output end of the driving mechanism. The driving mechanism drives the pin 42 to move so that the pin 42 can protrude from the adsorption surface 311.

[0058] The suction cup 3 includes a housing 31 and a connecting cylinder 32. The connecting cylinder 32 is disposed on the main body 1, and the housing 31 is disposed at the bottom of the connecting cylinder 32. The housing 31 is provided with a first mounting position 313 for accommodating the magnetic suction device 5.

[0059] An air cavity 316 is provided in the side wall of the housing 31, and a suction port 312 is provided at the bottom of the air cavity 316, forming the adsorption surface 311. An air inlet channel 321 is provided in the connecting cylinder 32, which communicates with the air cavity 316. An air inlet port communicating with a vacuum generator is provided on the air inlet channel 321. More preferably, a sealing ring 315 is snapped into the suction port 312.

[0060] The sealing ring 315 can improve the sealing performance of the suction port 312, so that the suction cup 3 can firmly pick up the items to be transferred through the suction port 312.

[0061] In this embodiment, the side wall of the housing 31 is provided with a plurality of second mounting positions 314, which are evenly distributed on the housing 31 along the circumference of the housing 31, and the telescopic pin structure 4 is fixed on the second mounting position 314.

[0062] Specifically, the second mounting position 314 penetrates the side wall of the housing 31, but the second mounting position 314 and the air cavity 316 are sealed to ensure the integrity of the air cavity 316, allowing a negative pressure to be formed in the air cavity 316 to adsorb items. The evenly distributed second mounting positions 314 allow the telescopic pin structure 4 to be evenly arranged on the housing 31. During use, the pins 42 can extend from multiple different directions simultaneously from the adsorption surface 311, thereby inserting into the item to be adsorbed, so that the item to be adsorbed is evenly stressed, ensuring that the item can be firmly adsorbed.

[0063] Example 4

[0064] like Figures 1-7 As shown, this embodiment includes the above-mentioned material suction and transfer device, including a main body 1, a suction cup 3 is provided at the bottom of the main body 1, an adsorption surface 311 is formed at the bottom of the suction cup 3, and a magnetic suction device 5 is provided in the suction cup 3.

[0065] The suction cup 3 is also provided with a telescopic pin structure 4. The telescopic pin structure 4 includes a driving mechanism and a pin 42. The driving mechanism is fixed on the suction cup 3, and the pin 42 is located at the output end of the driving mechanism. The driving mechanism drives the pin 42 to move so that the pin 42 can protrude from the adsorption surface 311.

[0066] The suction cup 3 includes a housing 31 and a connecting cylinder 32. The connecting cylinder 32 is disposed on the main body 1, and the housing 31 is disposed at the bottom of the connecting cylinder 32. The housing 31 is provided with a first mounting position 313 for accommodating the magnetic suction device 5.

[0067] An air chamber 316 is provided in the side wall of the housing 31. A suction port 312 is provided at the bottom of the air chamber 316. The suction port 312 forms the adsorption surface 311. An air inlet channel 321 is provided in the connecting cylinder 32. The air inlet channel 321 is connected to the air chamber 316. An air inlet connected to a vacuum generator is provided on the air inlet channel 321.

[0068] The side wall of the housing 31 is provided with a plurality of second mounting positions 314, which are evenly distributed on the housing 31 along the circumference of the housing 31. The telescopic pin structure 4 is fixed on the second mounting position 314.

[0069] In this embodiment, the driving mechanism is a needle cylinder 41, which is fixed on the second mounting position 314, and the piston rod of the needle cylinder 41 is arranged facing the adsorption surface 311.

[0070] The pin 42 is fixed to the piston rod of the needle-type cylinder 41, and the angle between the axis of the pin 42 and the adsorption surface 311 is 30°-45°. This angle allows the pin 42 to be inserted into the item to be transferred at an angle during movement, maintaining good clamping ability and preventing the item from slipping and falling off during movement. It should be noted that this angle refers to the acute angle formed by the axis of the pin 42 and the adsorption surface 311.

[0071] It should be noted that the needle-type cylinder 41 of this application needs to be connected to an external air source so that the cylinder can drive the insertion needle 42 to move. In practical applications, the axis of the insertion needle 42 coincides with the axis of the piston rod of the needle-type cylinder 41.

[0072] Multiple telescopic pin structures 4 allow the pins 42 to be inserted into the items to be transported from different directions during the use of the transport device, so that the items to be transported are subjected to uniform force and can be more firmly sucked up and transported.

[0073] The following describes the operation of the material suction and transfer device of this application. The transfer device of this application can be applied to the suction and transfer of stacked items. For example, the transfer of stacked cylinders. The stacking of cylinders involves first placing one layer of cylinders, then separating them with rigid boards or soft cardboard, and then stacking another layer of cylinders, and so on.

[0074] When using the material suction and transfer device of this application to suction cylinders, the magnetic suction device 5 can be used to directly suction the cylinders, and then the magnetic suction device 5 releases the cylinders when they move to the target position. After the cylinder transfer of one layer is completed, it is necessary to suction rigid or flexible boards.

[0075] If a rigid board is used as a separator, the suction cup 3 can be used to pick it up directly. Because rigid boards are not easily deformed, the suction cup 3 creates a certain negative pressure that can lift the rigid board. However, for flexible boards, which are easily deformed, the suction cup 3 cannot easily lift them. In this case, the telescopic pin structure 4 needs to move so that the pin 42 can be inserted into the flexible board. This lifts the flexible board and restricts its deformation, allowing the suction cup 3 to pick it up. Therefore, the suction device of this application can pick up both rigid boards and flexible boards. When used in cylinder transfer, it eliminates the need to switch clamps, making it convenient and cost-effective.

[0076] Example 5

[0077] like Figures 1-7 As shown, this embodiment includes the above-mentioned material suction and transfer device, including a main body 1, a suction cup 3 is provided at the bottom of the main body 1, an adsorption surface 311 is formed at the bottom of the suction cup 3, and a magnetic suction device 5 is provided in the suction cup 3.

[0083] The insertion pin 42 is fixed on the piston rod of the needle cylinder 41, and the angle between the axis of the insertion pin 42 and the adsorption surface 311 is 30°-45°.

[0084] In this embodiment, a specific implementation of the magnetic attraction device 5 is provided. The magnetic attraction device 5 includes a mounting plate 51 and a permanent magnet 52.

[0085] The suction device of this application can attract items to be transferred by a permanent magnet 52, which is convenient to use. Moreover, the permanent magnet 52 can not pick up or release items in time, which helps to improve the transfer efficiency of items and allows items to be accurately released to the designated location.

[0086] In another embodiment, the magnetic attraction device 5 of this application may also be an electromagnet.

[0087] Example 6

[0088] like Figures 1-7 As shown, this embodiment includes the above-mentioned material suction and transfer device, including a main body 1, a suction cup 3 is provided at the bottom of the main body 1, an adsorption surface 311 is formed at the bottom of the suction cup 3, and a magnetic suction device 5 is provided in the suction cup 3.

[0089] The suction cup 3 is also provided with a telescopic pin structure 4. The telescopic pin structure 4 includes a driving mechanism and a pin 42. The driving mechanism is fixed on the suction cup 3, and the pin 42 is located at the output end of the driving mechanism. The driving mechanism drives the pin 42 to move so that the pin 42 can protrude from the adsorption surface 311.

[0090] The suction cup 3 includes a housing 31 and a connecting cylinder 32. The connecting cylinder 32 is disposed on the main body 1, and the housing 31 is disposed at the bottom of the connecting cylinder 32. The housing 31 is provided with a first mounting position 313 for accommodating the magnetic suction device 5.

[0091] An air chamber 316 is provided in the side wall of the housing 31. A suction port 312 is provided at the bottom of the air chamber 316. The suction port 312 forms the adsorption surface 311. An air inlet channel 321 is provided in the connecting cylinder 32. The air inlet channel 321 is connected to the air chamber 316. An air inlet connected to a vacuum generator is provided on the air inlet channel 321.

[0092] The sidewall of the housing 31 is provided with a plurality of second mounting positions 314, which are evenly distributed along the circumference of the housing 31. The telescopic pin structure 4 is fixed on the second mounting position 314. The driving mechanism is a needle cylinder 41, which is fixed on the second mounting position 314, and the piston rod of the needle cylinder 41 is oriented towards the adsorption surface 311. The pin 42 is fixed on the piston rod of the needle cylinder 41, and the angle between the axis of the pin 42 and the adsorption surface 311 is 30°-45°.

[0093] The magnetic attraction device 5 includes a mounting plate 51 and a permanent magnet 52. The mounting plate 51 is movably disposed in the first mounting position 313. The permanent magnet 52 is detachably disposed at the bottom of the mounting plate 51. A first buffer spring 53 is disposed at the top of the mounting plate 51. One end of the first buffer spring 53 abuts against the top of the mounting plate 51, and the other end is fixed in the first mounting position 313.

[0094] In this embodiment, the main body 1 includes a connecting rod 12, the bottom of which is fixedly connected to the connecting cylinder 32. A push rod cylinder 2 is also provided at the bottom of the connecting rod 12. A push rod 21 is provided at the top of the mounting plate 51. One end of the push rod 21 passes through the connecting cylinder 32 and is fixedly connected to the output end of the push rod cylinder 2.

[0095] The push rod 21 is driven by the push rod cylinder 2 to move, which can drive the mounting plate 51 to move. When the mounting plate 51 moves upward momentarily, the magnetic force of the permanent magnet 52 disappears momentarily, thus completing the release of the item.

[0096] The working principle of the magnetic attraction device 5 in this application is as follows: When it is necessary to attract iron products, the device is moved directly above the iron products so that the permanent magnet 52 comes into contact with the iron products, thereby attracting them. When it is necessary to release the iron products from the permanent magnet 52, the push rod cylinder 2 drives the push rod 21 to move upward, thereby driving the permanent magnet 52 to move upward. At the instant the permanent magnet 52 moves upward, the magnetic force disappears instantly, thus completing the release of the items.

[0131] The following describes in detail the working process of the material transfer system of this application, taking the stacked cylinders in the material suction and transfer device of this application as an example:

[0132] Step 1: When the cylinder is being picked up, the buffer seat 112 is initially positioned between the two position sensors 116. As the transfer device presses down, the buffer seat 112 moves upward relative to the position sensors 116, compressing the second buffer spring 113. When the sensing screw 117 on the buffer seat 112 aligns with the upper position sensor 116, the transfer device stops pressing down. During this pressing process, the permanent magnet 52 compresses the first buffer spring 53, causing the entire magnetic suction device 5 to retract into the housing 31 of the suction cup 3. At this point, the permanent magnet 52 comes into contact with the cylinder, allowing it to be picked up.

[0133] Step Two: After the permanent magnet 52 attracts the cylinder, the robotic arm controls the transfer device to move upward. The second buffer spring 113 resets, pushing the buffer seat 112 downward. The robotic arm controls the movement of the transfer device. When the transfer device moves to the target position, the push rod cylinder 2 drives the push rod 21 upward, causing the permanent magnet 52 to move upward instantaneously. The permanent magnet 52 loses its magnetism, completing the release of the cylinder.

[0134] This process is repeated to complete the transfer of all cylinders.

[0135] Step 3:

[0136] After the cylinder transfer is completed, a vacuum generator evacuates the air, creating a negative pressure in the air chamber 316 to suck up the rigid plate. Then, the transfer device moves to the target position, and the vacuum generator supplies air into the air chamber 316 to release the rigid plate.

[0137] This process can also involve transferring a flexible plate. During the suction of the flexible plate, the pin 42 of the telescopic pin 42 mechanism extends and inserts into the flexible plate, at which point the suction cup 3 picks up the flexible plate. Then, the transfer device moves upward, and after moving to the target position, the pin 42 retracts, at which point the suction cup 3 releases the flexible plate, completing the transfer of the flexible plate.

[0138] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this application. Any specific values ​​in all examples shown and discussed herein should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0139] 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.

[0140] 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.

[0141] 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.
