Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a crimping device, assembly equipment and crimping method. Background Technology

[0002] Most current connectors are elongated and strip-shaped, and the individual components of a connector are correspondingly tubular or cylindrical. Therefore, connectors are typically assembled by axially nesting them together. However, misalignment of the connector components during axial nesting can occur, affecting assembly. Summary of the Invention

[0003] Therefore, it is necessary to provide a crimping device, assembly equipment, and crimping method to address the problem of misalignment during axial sleeve assembly.

[0004] The first aspect of this application provides a crimping device, which includes a material transfer assembly and an alignment assembly. The material transfer assembly includes a first gripper that is movable between a material picking position and a pressing position. The first gripper in the material picking position is used to pick up an outer casing. The first gripper in the pressing position is used to move toward the inner casing to press the outer casing onto the inner casing which is fitted with an intermediate component. The alignment assembly includes a second gripper that is capable of clamping and opening. When the second gripper is clamped, it can hold the outer periphery of the intermediate component so that the intermediate component is aligned with the inner hole of the outer casing along the pressing direction of the first gripper.

[0005] In one embodiment, the material transfer assembly includes a first longitudinal transfer unit connected to the first gripper to drive the first gripper at the pressing position to move along the pressing direction. The centering assembly includes a second longitudinal transfer unit connected to the second gripper. When the first gripper presses to the position where a portion of the outer sleeve is fitted onto the intermediate piece, the second longitudinal transfer unit drives the second gripper to move away from the first gripper along the pressing direction.

[0006] In one embodiment, the second gripper includes a first clamping portion and a second clamping portion, which are movable along a first direction. The first clamping portion is provided with a plurality of first claw portions arranged at intervals along the first direction, and the second clamping portion is provided with a plurality of second claw portions arranged at intervals along the first direction. Along the first direction, the first claw portions and the second claw portions are arranged alternately at intervals, and a first claw portion and an adjacent second claw portion cooperate to clamp a middle member.

[0007] In one embodiment, the second gripper includes two claw portions that can move toward each other to clamp around the outer periphery of the intermediate member; the two claw portions have an arc-shaped wall on the side facing each other, and when the two claw portions are clamped, the two arc-shaped walls are joined together to form a closed centering hole.

[0008] In one embodiment, the first gripper has a clamping hole, and the second gripper has a centering hole, the centering hole being coaxially arranged with the clamping hole at the pressing position.

[0009] In one embodiment, the crimping device further includes a feeding assembly for conveying the outer jacket; the second gripper at the picking position has an overlapping area with the feeding assembly in the orthographic projection along the pressing direction for picking up the outer jacket.

[0010] In one embodiment, the material conveying assembly includes a track and a lifting platform. The track has a material conveying channel extending along a second direction, and at least a portion of the material conveying channel is closed relative to the outside in a direction perpendicular to the second direction. The lifting platform has an open pick-up position located at one end of the material conveying channel, and the pick-up position is used to receive the outer casing output from the material conveying channel. The lifting platform is capable of lifting the outer casing located at the pick-up position in a direction perpendicular to the second direction toward the side where the material conveying assembly is located, and blocking the material conveying channel.

[0011] A second aspect of this application provides an assembly apparatus, the assembly apparatus including a platform and a pressing device as described above, the platform being used to place an inner shell with an intermediate component, and the pressing device being used to press an outer shell onto the outer periphery of the intermediate component, so that the inner shell, the intermediate component, and the outer shell are sequentially fitted from the inside out.

[0012] A third aspect of this application provides a pressing method, the pressing method comprising: driving a first gripper to move an outer sleeve to a pressing position; driving a second gripper to grip an intermediate piece sleeved on the outer sleeve, so that the intermediate piece is longitudinally aligned with the inner hole of the outer sleeve; driving the first gripper located at the pressing position to press down longitudinally, thereby sleeved the outer sleeve over the intermediate piece.

[0013] In one embodiment, after the second gripper is driven to clamp the intermediate piece outside the inner shell, the pressing method further includes: when the first gripper is pressed to the position where a portion of the outer shell is fitted onto the intermediate piece, the second gripper is driven to press down synchronously with the first gripper.

[0014] In the aforementioned crimping device, the second gripper can hold the outer periphery of the intermediate piece fitted onto the inner shell, aligning the intermediate piece with the inner hole of the outer shell along the pressing direction of the first gripper, thus improving the alignment accuracy during axial fitting assembly of the outer shell and the intermediate piece. Consequently, when the material transfer assembly drives the outer shell for pressing, it can easily fit over the inner shell and the intermediate piece, improving the smoothness of the pressing process.

Detailed Implementation

[0022] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application 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 application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0023] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0024] 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 application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In this application, unless otherwise expressly 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 expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] In this application, unless otherwise expressly 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.

[0027] 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 application are for illustrative purposes only and do not represent the only possible implementation.

[0028] Current connectors have an elongated, strip-like outline, and their individual components also have corresponding tubular or cylindrical shapes. For example, as... Figure 1 and Figure 2 As shown, the connector may include an inner shell 21, an intermediate component 22, and an outer shell 23, which are sequentially fitted together from the inside out. Therefore, assembly (referring to the assembly of the three components) can be completed by successively fitting the intermediate component 22 and the outer shell 23 onto the inner shell 21. However, when there is axial misalignment among the three components, simple axial insertion often fails to effectively achieve the fitting assembly. The misalignment problem mostly occurs during the assembly of the outer shell 23, specifically, misalignment between the outer shell 23 and the intermediate component 22. Simply put, when assembling the outer shell 23, the inner shell 21, as the innermost component, can often be fixed using a fixture. The intermediate component 22 is fitted onto the inner shell 21, and the outer shell 23 is fitted onto it. If there is a certain amount of play between the intermediate component 22 and the inner shell 21, the intermediate component 22 is prone to misalignment, causing misalignment between the intermediate component 22 and the inner hole 24 of the outer shell 23. Therefore, during the press-fitting of the outer shell 23, there is a problem where the end face of the outer shell 23 abuts against the intermediate component 22, preventing successful installation.

[0029] To address the aforementioned problems, this application provides a crimping device including an alignment component. During crimping, the alignment component can grip the outer periphery of the intermediate part to position it, aligning the intermediate part with the inner hole of the outer sleeve, thus improving the smoothness of axial crimping. The axial direction described in various embodiments of this application can be parallel to the crimping direction mentioned below, such as... Figure 1As indicated by reference numeral O. The following description, in conjunction with the accompanying drawings and specific embodiments, details the crimping device and assembly equipment including the crimping device provided in various embodiments of this application.

[0030] See Figures 1 to 3 An assembly device 10 provided in one embodiment of this application is used to assemble a workpiece 20, which includes an inner shell 21, an intermediate part 22, and an outer shell 23 sequentially fitted from the inside out. The assembly device 10 includes a pressing device 11 and a platform 12. The platform 12 is used to place the inner shell 21, on which the intermediate part 22 is fitted, and the pressing device 11 is used to press the outer shell 23 onto the outer periphery of the intermediate part 22, so that the inner shell 21, intermediate part 22, and outer shell 23 are sequentially fitted from the inside out. It is understood that the assembly device 10 can assemble the entire workpiece 20, while the pressing device 11 provided in various embodiments of this application mainly focuses on pressing the outer shell 23. That is, before the pressing device 11 presses the outer shell 23, the semi-finished workpiece 20 has already been assembled into its current form by other devices included in the assembly device 10. Figure 2 The state shown (i.e., the state in which the intermediate component 22 is fitted into the inner shell 21).

[0031] Please see Figure 3 One embodiment of this application provides a crimping device 11, which includes a material transfer assembly 100 and a centering assembly 200. The material transfer assembly 100 includes a first gripper 110, which is movable between a material picking position and a pressing position. In the material picking position, the first gripper 110 is used to pick up the outer sleeve 23; in the pressing position, the first gripper 110 is used to move towards the inner shell 21 to press the outer sleeve 23 onto the inner shell 21, which contains the intermediate member 22. The centering assembly 200 includes a second gripper 210, which is capable of clamping and opening. When the second gripper 210 is clamped, it can hold the outer periphery of the intermediate member 22, aligning the intermediate member 22 with the inner hole 24 of the outer sleeve 23 along the pressing direction K of the first gripper 110.

[0032] In the aforementioned crimping device 11, when the second gripper 210 clamps, it can hold the outer periphery of the intermediate piece 22 fitted onto the inner shell 21, aligning the intermediate piece 22 with the inner hole 24 of the outer shell 23 along the pressing direction K of the first gripper 110, thus improving the alignment accuracy when the outer shell 23 and the intermediate piece 22 are axially fitted together. Therefore, when the material transfer assembly 100 drives the outer shell 23 to press, it can easily fit over the inner shell 21 and the intermediate piece 22, improving the smoothness of the pressing process.

[0033] It should be noted that the above example illustrates the possibility of misalignment of the intermediate component 22 by illustrating the existence of a space between the intermediate component 22 and the inner shell 21. However, there are many reasons that could cause misalignment of the intermediate component 22, such as the intermediate component 22 itself being deformable. The embodiments of this application do not limit the causes of misalignment between the intermediate component 22 and the outer shell 23. The crimping device 11 provided in the embodiments of this application can handle various situations of misalignment of the intermediate component 22.

[0034] Regarding the centering component 200, it is understood that if the outer sleeve 23 is assembled in place, but a portion of the intermediate component 22 is still exposed outside the outer sleeve 23, the second gripper 210 can hold the exposed portion of the intermediate component 22 outside the outer sleeve 23 to reduce interference with the pressing process of the outer sleeve 23. Alternatively, the second gripper 210 can be configured to have a sufficiently small thickness so that it can be accommodated between the intermediate component 22 and the outer sleeve 23. Once the outer sleeve 23 is assembled in place, the second gripper 210 can be pulled out from inside the outer sleeve 23.

[0035] Alternatively, in one embodiment, at least during one stage of the movement of the first gripper 110 along the pressing direction K, the second gripper 210 moves away from the first gripper 110 to reduce interference with the pressing motion of the first gripper 110 driving the outer sleeve 23. For example, when the first gripper 110 presses down to the position where a portion of the outer sleeve 23 is fitted onto the intermediate piece 22, the second gripper 210 moves away from the first gripper 110 along the pressing direction K to avoid the first gripper 110. Since part of the structure of the intermediate piece 22 has already entered the inner hole 24 of the outer sleeve 23, the outer sleeve 23 can be completely fitted onto the outer sleeve 22 by gradually pressing down along the outer periphery of the intermediate piece 22. Therefore, at this time, the second gripper 210 has almost completed the centering task, so driving the second gripper 210 to press down also avoids the first gripper 110, providing space for the fitting of the outer sleeve 23.

[0036] Please see Figure 3 and Figure 4 In one embodiment, the material transfer assembly 100 includes a first longitudinal transfer unit 120, which is connected to a first gripper 110 to drive the first gripper 110, which is in a pressing position, to move along the pressing direction K. The centering assembly 200 includes a second longitudinal transfer unit 220, which is connected to a second gripper 210 and can also drive the second gripper 210 to move along the pressing direction K. When the first gripper 110 presses onto a portion of the outer sleeve 23 and places it on the middle piece 22, the second longitudinal transfer unit 220 drives the second gripper 210 to move along the pressing direction K away from the first gripper 110, providing space for the pressing and fitting action of the outer sleeve 23.

[0037] Furthermore, when the first gripper 110 presses onto a portion of the outer sleeve 23 and positions it within the intermediate piece 22, the second longitudinal movement unit 220 drives the second gripper 210 to move synchronously with the first gripper 110. It can be understood that the first gripper 110 clamps and presses the outer sleeve 23 from top to bottom, meaning that along the pressing direction K, the first gripper 110 is positioned above the second gripper 210. Therefore, by configuring the second gripper 210 to move synchronously with the first gripper 110, the second gripper 210 can always pass through the various local areas along the axial direction of the intermediate piece 22 before the first gripper 110, thereby positioning it and improving the alignment accuracy between each local area and the inner hole 24 of the outer sleeve 23. This reduces the probability of jamming between the intermediate piece 22 and the outer sleeve 23 in the middle or tail area of ​​the intermediate piece 22, thus hindering assembly.

[0038] In one embodiment, the outer shell 23, the intermediate component 22, and the inner shell 21 can be coaxially connected. In this case, the second gripper 210's alignment and positioning of the intermediate component 22 involves pushing the intermediate component 22 to be coaxially aligned with the outer shell 23 in the press-fit position. Please refer to [link / reference]. Figures 3 to 5 In one embodiment, the first gripper 110 has a clamping hole 111, and the second gripper 210 has a centering hole 210a, which is coaxially arranged with the clamping hole 111 in the pressing position. Thus, after the second gripper 210 clamps, the intermediate part 22 can be coaxially arranged with the outer sleeve 23 in the pressing position. It should be noted that when the outer sleeve 23 and the intermediate part 22 have other positional relationships, the relationship between the centering hole 210a and the clamping hole 111 can be adjusted accordingly, so that the second gripper 210 can always push the intermediate part 22 into alignment.

[0039] Please see Figure 4 and Figure 5 In one embodiment, the second gripper 210 includes two gripper portions 210b, which are capable of moving towards each other to clamp and hold the intermediate member 22 on its outer periphery. The sides of the two gripper portions 210b facing each other have arc-shaped walls, which join together to form a closed centering hole 210a when the gripper portions 210b are clamped. Therefore, all areas of the inner wall of the centering hole 210a can be used to position the intermediate member 22, improving the positioning effect.

[0040] In one embodiment, the platform 12 can support multiple inner shells 21 and intermediate components 22. The first gripper 110 can simultaneously grip multiple outer shells 23, and the second gripper 210 can simultaneously position multiple intermediate components 22. Thus, pressing down with the first gripper 110 can simultaneously press-fit multiple outer shells 23, improving efficiency.

[0041] Please see Figures 3 to 5In one embodiment, the material transfer assembly 100 further includes a first clamping unit 130 connected to a first gripper 110, and the first clamping unit 130 is used to drive the first gripper 110 to open and close. The centering assembly 200 further includes a second clamping unit 230. The second gripper 210 includes a first clamping portion 211 and a second clamping portion 212, which are movable along a first direction S1. The second clamping unit 230 is connected to the first clamping portion 211 and the second clamping portion 212 respectively, and the second clamping unit 230 can drive the first clamping portion 211 and the second clamping portion 212 to move towards and away from each other, so that the second gripper 210 opens and closes.

[0042] The first clamping portion 211 is provided with a plurality of first claw portions 213 arranged at intervals along the first direction S1, and the second clamping portion 212 is provided with a plurality of second claw portions 214 arranged at intervals along the first direction S1. Along the first direction S1, the first claw portions 213 and second claw portions 214 are arranged alternately at intervals, with one first claw portion 213 and its adjacent second claw portion 214 cooperating to clamp the intermediate member 22. That is, one first claw portion 213 and its adjacent second claw portion 214 cooperate to form a pair of center holes 210a, and the plurality of first claw portions 213 cooperate one-to-one with the plurality of second claw portions 214 to form a plurality of centering holes 210a. Therefore, when the first clamping portion 211 and the second clamping portion 212 move towards or away from each other, the plurality of first claw portions 213 and the plurality of second claw portions 214 can be opened and closed simultaneously. It is understood that any first claw portion 213 and any second claw portion 214 can be provided with the arc-shaped wall as described above.

[0043] Please see Figure 4 In one embodiment, the second clamping unit 230 is connected to the second longitudinal moving unit 220, and the second longitudinal moving unit 220 is used to drive the second clamping unit 230 and the second gripper 210 to move along the pressing direction K.

[0044] Please see Figure 3 In one embodiment, the material transfer assembly 100 further includes a material transfer drive unit 140, which is connected to the first gripper 110. The material transfer drive unit 140 is used to drive the first gripper 110 to move between the material pick-up position and the pressing position. Further, the material transfer drive unit 140 may be connected to a first longitudinal transfer unit 120 to drive the first longitudinal transfer unit 120 and the first gripper 110 to move along the second direction S2 between the material pick-up position and the pressing position.

[0045] Please see Figure 6In one embodiment, the crimping device 11 further includes a conveying assembly 300 for conveying the outer jacket 23. The second gripper 210, positioned in the picking position, has an overlapping area with the conveying assembly 300 along the pressing direction K, for picking up the outer jacket 23. This configuration allows the second gripper 210 to not only press the outer jacket 23 but also pick it up as it moves along the pressing direction K.

[0046] Please continue reading. Figure 6 In one embodiment, the material conveying assembly 300 includes a track 310 and a lifting platform 320. The track 310 can extend along a second direction S2, and the lifting platform 320 is located at one end of the track 310. The track 310 has a material conveying channel 311 extending along the second direction S2, which is used to convey the outer jacket 23. That is, the material conveying assembly 300 can convey the outer jacket 23 along the second direction S2. In the direction perpendicular to the second direction S2, at least a portion of the material conveying channel 311 is relatively closed to the outside to improve the stability of conveying the workpiece 20 and reduce external interference. Alternatively, the material conveying channel 311 can also have a connecting seam 312 communicating with the outside. When blockage occurs in the material conveying channel 311, a clearing tool can be inserted into the material conveying channel 311 through the connecting seam 312 to clear the blockage. The lifting platform 320 has an open pick-up position 321. Located at one end of the conveying channel 311, the pick-up position 321 receives the outer jacket 23 output from the conveying channel 311; that is, the conveying channel 311 transports the outer jacket 23 to the pick-up position 321 of the lifting platform 320. The lifting platform 320 can lift the outer jacket 23 located at the pick-up position 321 along a direction perpendicular to the second direction S2, towards the side where the material transfer assembly 100 is located, and block the conveying channel 311. Because the lifting platform 320 is open, the first gripper 110 can easily pick up the outer jacket 23 located at the pick-up position 321. Furthermore, the lifting platform 320 can lift the workpiece 20 located at the pick-up position 321 and block the conveying channel 311, thereby preventing the outer jacket 23 from continuously being conveyed out of the conveying channel 311, which would cause instability in the position of the outer jacket 23 at the pick-up position 321.

[0047] Please see Figure 6 In one embodiment, the material conveying assembly 300 includes a lifting drive unit 330, which is connected to a lifting platform 320 to drive the lifting platform 320 to lift along the pressing direction K, so that the lifting platform 320 rises to the position of blocking the material conveying channel 311 and drives the workpiece 20 located at the material taking position 321 to lift.

[0048] In one embodiment, the conveying assembly 300 may further include a conveying drive unit (not shown, the same below) for driving the outer jacket 23 to be conveyed along the conveying channel 311. The conveying drive unit may be located at the end of the track 310 away from the lifting platform 320. For example, the conveying drive unit may be configured as a vibratory feeder.

[0049] In one embodiment, the second clamping unit 230, the first longitudinal moving unit 120, the second longitudinal moving unit 220, the material transfer driving unit 140, and the lifting driving unit 330 can be driven by linear driving methods such as cylinders, hydraulic cylinders, electric push rods, and pneumatic slide rails, and there are no limitations on them in each embodiment.

[0050] In one embodiment, the crimping device 11 further includes a first support 400 and a second support 500, with the material transfer component 100 disposed on the first support 400 and the centering component 200 disposed on the second support 500. In one embodiment, the first support 400 and the second support 500 may be integrally formed to form a base (not shown in the figure, the same below), and both the material transfer component 100 and the centering component 200 are disposed on the base.

[0051] In one embodiment, the assembly equipment 10 includes a transport device (not shown, the same below) connected to a platform 12, which is capable of driving the platform 12 to switch the platform 12 at the centering component 200.

[0052] It should be noted that the second longitudinal movement unit 220 can not only drive the second gripper 210 to press down to avoid the first gripper 110, but also drive the second gripper 210 to lift up to avoid the assembled workpiece 20, facilitating the switching of the platform 12. Similarly, the first longitudinal movement unit 120 can drive the first gripper 110 to lift up.

[0053] One embodiment of this application also provides a pressing method, which can be used in the pressing device 11 and assembly equipment 10 as described in various embodiments. The pressing method includes:

[0054] S1, drive the first gripper 110 to move the outer sleeve 23 to the pressing position. As mentioned above, the first gripper 110 can be driven by the material transfer drive unit 140 to move the outer sleeve 23 to the pressing position.

[0055] S2, drive the second gripper 210 to grip the intermediate piece 22 sleeved outside the inner shell 21, so that the intermediate piece 22 is longitudinally aligned with the inner hole 24 of the outer shell 23.

[0056] S3, drive the first gripper 110 located in the press position to press down longitudinally, and put the outer sleeve 23 over the middle part 22.

[0057] In the above pressing method, before pressing the outer jacket 23, the intermediate part 22 is clamped by the second gripper 210, so that the intermediate part 22 is positioned to be aligned with the inner hole 24 of the outer jacket 23, which facilitates the pressing of the outer jacket 23.

[0058] In one embodiment, after the second gripper 210 clamps the intermediate piece 22 sleeved outside the inner shell 21, the press-fitting method further includes:

[0059] S4, when the first gripper 110 presses onto a portion of the outer sleeve 23 and positions it within the intermediate piece 22, the second gripper 210 is driven to press down synchronously with the first gripper 110. Thus, the second gripper 210 provides space for the pressing down of the first gripper 110. Furthermore, since the pressing down of the first gripper 110 and the second gripper 210 is synchronized, the second gripper 210 always passes through the various axial local areas of the intermediate piece 22 before the first gripper 110 to position it, improving the alignment accuracy between each local area and the inner hole 24 of the outer sleeve 23, and reducing the probability of jamming between the intermediate piece 22 and the outer sleeve 23 in the middle or tail area, thus hindering assembly.

[0060] In one embodiment, when the outer jacket 23 is assembled in place, the press-fitting method further includes:

[0061] S5 drives the first gripper 110 to open.

[0062] S6 drives the second gripper 210 to open.

[0063] S7 drives the first gripper 110 to lift.

[0064] S8 drives the second gripper 210 to lift.

[0065] S9, drive the first gripper 110 to move to the picking position to pick up the jacket 23 to be assembled.

[0066] S10, drive stage 12 to move to switch another stage 12 to the centering component 200.

[0067] By repeating steps S1 to S10 above, the outer jacket 23 can be continuously assembled.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
