Description

Technical Field

[0001] This application relates to the field of automation equipment technology, and in particular to an automatic beam-lifting assembly device. Background Technology

[0002] In the mass production of plastic buckets or other similar containers, the plastic bucket body is produced by injection molding machine, and then conveyed to the corresponding assembly station via conveyor line to complete the installation of the lifting beam to obtain the final finished product.

[0003] In the existing barrel production process, multiple injection molding machines are usually used to produce various sizes of plastic barrels at the same time so that the production speed of the plastic barrels can match the assembly speed of the lifting beam.

[0004] However, different injection molding machines produce plastic buckets of different sizes. Therefore, manual sorting is usually required to ensure that the plastic buckets are assembled at the appropriate assembly stations. This manual intervention reduces the level of automation in production, negatively impacting both manufacturing costs and efficiency. Summary of the Invention

[0008] In some embodiments, the controller is further configured to: control the second blocking component to switch to a blocking state when the workpiece to be assembled matches the target specification, so that the workpiece to be assembled stays at the corresponding assembly station; and control the first blocking component to switch to a blocking state when the workpiece to be assembled that matches the target specification has completely passed through the sensing mechanism, so as to restrict the remaining workpieces to be assembled from entering the assembly station.

[0009] In some embodiments, the first blocking assembly has the same structure as the second blocking assembly; the first blocking assembly includes: a pair of blocking members; the pair of blocking members are disposed opposite each other on both sides of the conveyor line; wherein, when the blocking mechanism is in a blocking state, at least a portion of the pair of blocking members approaches each other to restrict the movement of the workpiece to be assembled; and when the blocking mechanism is in a retracted state, at least a portion of the pair of blocking members moves away from each other.

[0010] In some embodiments, the blocking component includes: a component support; the component support is fixed to one side of the conveyor line; a blocking block; the blocking block is movable relative to the component support between an extended position and a retracted position, and is provided with a contact surface adapted to the surface of the workpiece to be assembled; a driving device; the driving device is fixed on the component support and is used to drive the blocking block to move; wherein, when in the extended position, the blocking block is located on the movement trajectory of the workpiece to be assembled; when in the retracted position, the blocking block is located outside the movement trajectory of the workpiece to be assembled.

[0029] The present application will now be described in detail with reference to specific embodiments. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present application.

[0030] It should be noted that, unless otherwise expressly specified and limited, the terms "center," "longitudinal," "lateral," "upper," "lower," "vertical," "horizontal," "inner," and "outer," etc., used in this specification to indicate orientation or positional relationships are based on the orientation or positional relationships 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 on this application. The terms "installed," "connected," "linked," and "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features; thus, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature; "multiple" means two or more; and "and / or" includes any and all combinations of one or more related listed items. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] A "lifting beam" refers to a component fixed to a plastic bucket or other similar container, allowing the user to lift it. Typical automated lifting beam assembly equipment can usually only automatically assemble lifting beams for buckets of specific sizes and cannot accommodate buckets of other sizes.

[0032] In the existing production process, multiple injection molding machines simultaneously produce barrels of various sizes and specifications. Before entering the automated assembly mechanism, these barrels need to be manually sorted to separate the different sizes and specifications for subsequent automated assembly. Furthermore, multiple additional automated assembly machines are required to accommodate the different barrel sizes. This additional setup leads to wasted production capacity and increased production line costs.

[0033] In the process of implementing this application, the applicant discovered that: by setting appropriate sensing and blocking mechanisms on the conveyor line, the operation of sorting by specification and size can be facilitated, so that barrels of different specifications can be mixed in the same automatic lifting beam assembly equipment, thereby effectively saving space and implementation costs, and also improving production efficiency.

[0034] Figure 1 This is a schematic diagram of the automatic beam assembly device provided in an embodiment of this application. Figure 1As shown, the automatic beam assembly device may include: a conveyor line 100, several beam assembly mechanisms 200, several sensing mechanisms 300, several blocking mechanisms 400, and a controller 500.

[0035] The conveyor line 100 is used to drive the workpiece to be assembled along a preset conveying direction. Specifically, any suitable type of conveyor line (e.g., roller conveyor, belt conveyor, or chain conveyor) can be selected according to actual needs, and it is configured with the required dimensions and conveying speed, etc., without specific limitations. In this embodiment, the term "workpiece to be assembled" is used to refer to the workpiece requiring the lifting beam assembly process, which can be a plastic barrel body or other similar container produced by an injection molding machine. "Conveying direction" indicates the direction in which the workpiece to be assembled moves within the conveyor line 100.

[0036] The beam-lifting assembly mechanism 200 is a component used for the automatic assembly of workpieces to be assembled. It can be used with any suitable type of automatic beam-lifting assembly equipment, and no specific limitation is made here. Figure 1 As shown, multiple lifting and assembly mechanisms 200 can be configured and arranged at intervals along the aforementioned transmission direction, thereby forming multiple assembly stations A spaced a certain distance apart on the conveyor line to meet the usage requirements of workpieces of different specifications to be assembled. The specific number of lifting and assembly mechanisms 200 can be determined by the types of workpieces to be assembled that may exist on the conveyor line.

[0037] In this embodiment, the term "target specification" is used to refer to the size and dimensions of the workpiece to be assembled corresponding to the beam-lifting assembly mechanism. In other words, a beam-lifting assembly mechanism is dedicated to automatically assembling and lifting beams for workpieces of a specific target specification.

[0038] The sensing mechanism 300 is a component paired with the lifting beam assembly mechanism 200. In this embodiment, "paired setup" refers to a configuration in which the sensing mechanisms 300 cooperate with each other and have a one-to-one correspondence. For example, the number of sensing mechanisms 300 may be the same as the number of lifting beam assembly mechanisms 200, and different sensing mechanisms 300 may be used to perform specification detection of the workpieces to be assembled for different lifting beam assembly mechanisms 200.

[0039] The sensing mechanism 300 can be used to detect the specifications of the workpiece to be assembled after passing through the sensing mechanism. Specifically, any suitable type of sensor can be selected according to the actual needs. For example, when detecting based on the height of the workpiece to be assembled, a height recognition sensor or a machine vision-based height sensor can be used to directly acquire the height of the workpiece to be assembled, thereby realizing the detection and judgment of the workpiece specifications.

[0040] In other embodiments, instead of using indirect detection, the workpiece specifications can be indirectly determined by detecting the workpiece height range within which the workpiece to be assembled is located. For example... Figure 2 As shown, the sensing mechanism 300 may include: a pair of mechanism supports 310 and two sets of through-beam sensors (321, 322).

[0041] The pair of mechanism brackets 310 are fixed on both sides of the conveyor line, arranged opposite each other. The mechanism brackets 310 can have any suitable structure, shape, and size, as long as they can provide sensor fixing positions that meet the usage requirements.

[0042] The through-beam sensors (321, 322) are a group of sensor devices mainly composed of a transmitter and a receiver. They can generate different signals depending on whether the receiver receives a signal from the transmitter (e.g., laser or infrared light), thereby helping the controller determine whether there is an opaque object or obstruction between the through-beam sensors. In this embodiment, as... Figure 2 As shown, the two parts of the through-beam sensor can be respectively mounted on a pair of mechanical supports to detect whether there is an obstruction at a specific height.

[0043] Furthermore, the two sets of through-beam sensors 321 and 322 are positioned at different heights. That is, through-beam sensors 321 and 322 are used to detect whether an object is passing through at different height positions. Therefore, by configuring appropriate control logic and suitable detection heights, the height range of the workpiece to be assembled can be determined.

[0044] In this embodiment, two sets of through-beam sensors are used to achieve height detection, which can effectively reduce the manufacturing cost of the sensing mechanism compared to height recognition sensors.

[0045] The blocking mechanism 400 is also paired with the lifting beam assembly mechanism 200. It is a component that can switch between blocking and retraction states, which can restrict the movement of the workpiece to be assembled on the conveyor line along the conveyor line's transmission direction, thereby keeping it at the assembly station to complete the automatic assembly of the lifting beam.

[0046] The controller 500 is the core control unit of the entire automatic beam assembly device. It can be any suitable type of electronic computing device with certain logical operation capabilities, depending on the actual needs; no specific limitations are made here.

[0047] In this embodiment, the controller 500 establishes an electrical connection or other communication channel with the sensing mechanism 300 and the blocking mechanism 400 respectively, so that it can control the blocking mechanism 400 to sort different workpieces to be assembled according to the specification detection results of the sensing mechanism 300.

[0048] In actual use, the workpiece to be assembled can move along a preset transmission direction under the drive of the conveyor line. When the workpiece passes one of the sensing mechanisms 300, the sensing mechanism generates a corresponding electrical signal and provides it to the controller.

[0049] The controller 500 can determine whether the specifications of the workpiece to be assembled match the target specifications of the corresponding lifting beam assembly mechanism 200 based on the electrical signal fed back by the sensing mechanism 300.

[0050] On one hand, upon confirming that the workpiece to be assembled conforms to the target specifications, the controller 500 can first send a control signal to switch the blocking mechanism 400 to the blocking state. The blocking mechanism 400, in the blocking state, restricts the workpiece to be assembled, preventing it from continuing to move with the conveyor line and stopping it at the corresponding assembly station. Then, the lifting beam assembly mechanism 200 can automatically assemble the workpiece at the assembly station. Finally, after the lifting beam assembly mechanism completes the automatic lifting beam assembly process, the controller can control the blocking mechanism 400 to switch to the retraction state. The assembled workpiece, driven by the conveyor line, continues to move along the preset transmission direction and leaves the assembly station.

[0051] On the other hand, if it is confirmed that the workpiece to be assembled does not conform to the target specifications, the controller 500 can control the blocking mechanism 400 to remain in the retracted state. As a result, the workpiece to be assembled that does not conform to the target specifications can be driven by the conveyor line 100, pass through the lifting beam assembly mechanism 200 that is currently paired with the sensing mechanism, and move to other assembly stations.

[0052] Through the above methods, the automatic beam assembly device provided in the application embodiment realizes the automatic sorting of assembly workpieces of different specifications, which can connect the upstream and downstream processes of the product production line, which is conducive to realizing unmanned production, effectively reducing costs and saving the floor space of the production line.

[0053] Figure 3 This is a schematic diagram of the blocking mechanism provided in an embodiment of this application. Figure 3 As shown, the blocking mechanism 400 may include: a first blocking component 410 and a second blocking component 420.

[0054] The first blocking component 410 and the second blocking component 420 are two independently controlled blocking components, both of which can switch between blocking and recovery states. In this embodiment, the first blocking component 410 and the second blocking component 420 adopt the same structure. In other embodiments, the first blocking component 410 and the second blocking component 420 may also adopt different structures; no specific limitations are imposed on the above-mentioned blocking components here.

[0055] Please continue reading. Figure 3 In this embodiment, the second blocking component 420 can be positioned at a corresponding location in assembly station A. The first blocking component 410 is positioned further forward along the transport direction, with a preset distance between them. The sensing mechanism 300 is positioned between the first blocking component 410 and the second blocking component 420. Specifically, this preset distance can be set by technicians according to actual needs and is an empirical value, which is not specifically limited here.

[0056] In other words, when the second blocking component 420 switches to the blocking state, it can restrict the workpiece to stay at the assembly station, while when the first blocking component 410 switches to the blocking state, it can restrict the workpiece to the assembly station and prevent it from entering the assembly station.

[0057] In some embodiments, with Figure 3 The controller can also be configured to execute, in accordance with the structural arrangement of the blocking mechanism and the sensing mechanism shown. Figure 4 The control method shown is designed to better automate the sorting of workpieces of different specifications.

[0058] like Figure 4 As shown, the control method includes the following steps:

[0059] S41. Receive the detection signal from the sensing mechanism and determine whether the workpiece to be assembled after passing through the sensing mechanism conforms to the target specifications. If yes, proceed to step S42; if no, proceed to step S46.

[0060] S42. Control the second blocking component to switch to blocking state so that the workpiece to be assembled stays at the corresponding assembly station.

[0061] The default state of the first and second blocking components is the recycling state.

[0062] S43. When it is determined that the workpiece to be assembled has completely passed through the sensing mechanism, the first blocking component is controlled to switch to the blocking state to restrict the remaining workpieces to be assembled from entering the assembly station.

[0063] The specific method for determining whether a workpiece has completely passed through the sensing mechanism can be determined by the specific settings of the sensing mechanism. For example, there is usually a certain gap between two adjacent workpieces to be assembled. Therefore, when the sensing mechanism generates a detection signal, it can be considered that the workpiece has begun to pass through the sensing mechanism, and when the detection signal disappears, it can be considered that the workpiece has completely passed through the sensing mechanism.

[0064] S44. Control the automatic beam lifting assembly mechanism to automatically lift and assemble the workpiece to be assembled.

[0065] S45. After the automatic assembly of the lifting beam is completed, control both the first blocking component and the second blocking component to switch to the retraction state, so that the assembled workpiece leaves the assembly station.

[0066] S46. Control both the first and second blocking components to remain in the retracted state to allow the workpiece to be assembled to pass through the current assembly station and move to other assembly stations with the conveyor line.

[0067] Finally, after step S45 or step S46 is completed, return to step S41 to sort the next workpiece to be assembled.

[0068] Specifically, to fully illustrate the specific structure of the blocking mechanism and the principle of restricting workpiece movement in the embodiments of this application, the first blocking component will be used as an example for detailed description below. Please continue reading. Figure 3 The first blocking assembly 410 may include a pair of blocking members (411, 412).

[0069] A pair of blocking components (411, 412) are disposed opposite each other on both sides of the conveyor line. In the blocking state, at least a portion of the pair of blocking components approaches each other and enters the projected space occupied by the conveyor line, restricting the movement of the workpiece to be assembled. In the retraction state, at least a portion of the pair of blocking components moves away from each other and no longer enters the projected space of the conveyor line, thus not affecting the movement of the workpiece.

[0070] Specifically, such as Figure 5 As shown, the blocking component 411 may include: a component support 4111; a blocking block 4112; and a driving device 4113.

[0071] The component support 4111 is fixed to one side of the conveyor line. It can have a suitable height to facilitate restraint at a position near the center of the workpiece.

[0072] The blocking block 4112 is a component that can reciprocate between an extended position and a retracted position relative to the component support 4111. It is provided with a contact surface adapted to the surface of the workpiece to be assembled, for example, as... Figure 5As shown, it can be equipped with an arc-shaped inclined surface S1 to fit the plastic bucket body.

[0073] The drive device 4113 is fixed to the component bracket 4111 and is used to drive the blocking block 4112 to move between the extended position and the retracted position. Specifically, the drive device 4113 can be any suitable type of actuation mechanism, as long as it can provide suitable power and guidance to guide the blocking block 4112 to move.

[0074] For example, the drive device 4113 can be a cylinder, with the stop block 4112 fixed to the end of the piston rod of the cylinder, thereby enabling movement between the extended position and the retracted position. Alternatively, the drive device 4113 can also be a component consisting of a motor and a guide mechanism, with the stop block 4112 disposed on the guide mechanism (such as a guide rod) and moved under the guidance of the guide mechanism by the driving force provided by the motor.

[0075] In this embodiment, for ease of description, "extended position" and "retracted position" are used to describe the different positions of the blocking block, corresponding to the two states of the blocking component. The "extended position" refers to the position of the blocking block when it is within the movement trajectory of the workpiece to be assembled, while the retracted position refers to the position of the blocking block when it is outside the movement trajectory of the workpiece to be assembled. In other words, when the blocking block is in the extended position, it can abut against the workpiece / workpiece to be assembled on the conveyor line, restricting its continued movement with the conveyor line; while in the retracted position, the blocking block does not affect the movement of the workpiece / workpiece to be assembled on the conveyor line.

[0076] To fully illustrate the working process and specific sorting principle of the automatic beam assembly device provided in the embodiments of this application, the following is combined with... Figure 6 The specific examples shown will be described in detail.

[0077] like Figure 6 As shown, the automatic beam assembly device includes: a conveyor line 100, a first beam assembly mechanism 201, a second beam assembly mechanism 202, a third beam assembly mechanism 203, a first sensing mechanism 301, a second sensing mechanism 302, a third sensing mechanism 303, a first blocking mechanism 401, a second blocking mechanism 402, a third blocking mechanism 403, and a controller (not shown).

[0078] The conveyor line 100 can be a basically straight conveyor line structure extending along a preset transmission direction X1. One end is the workpiece inlet, and the other end is the workpiece outlet. The pre-made plastic barrel can be continuously fed in from the workpiece inlet, and after passing through the automatic installation process of the lifting beam, it leaves from the workpiece outlet.

[0079] In this embodiment, the input plastic bucket body has three different dimensions: a first target size, a second target size, and a third target size, with the workpiece height increasing sequentially. In other words, the height of the plastic bucket body with the first target size is lower than that with the second target size, and the height of the plastic bucket body with the second target size is lower than that with the third target size. For simplicity, as... Figure 7 As shown, the workpiece heights of the first target specification, the second target specification, and the third target specification are referred to as the first workpiece height L1, the second workpiece height L2, and the third workpiece height L3, respectively.

[0080] The first lifting beam assembly mechanism 201, the second lifting beam assembly mechanism 202, and the third lifting beam assembly mechanism 203 are mechanisms used to automatically assemble lifting beams for plastic buckets of first, second, and third target specifications, respectively. They are arranged sequentially at intervals along the aforementioned transmission direction, forming corresponding first, second, and third assembly stations on the conveyor line, and can automatically complete the lifting beam assembly for workpieces (such as plastic buckets) resting at the assembly stations. In this embodiment, dashed boxes are used to roughly illustrate the lifting beam assembly mechanism for ease of demonstration. The specific lifting beam assembly mechanism can be selected from any suitable type of automated assembly equipment according to actual needs, and no specific limitation is made here.

[0081] The first sensing mechanism 301, the second sensing mechanism 302, and the third sensing mechanism 303 are respectively paired with the first lifting beam assembly mechanism 201, the second lifting beam assembly mechanism 202, and the third lifting beam assembly mechanism 203, and are used to detect the specifications and dimensions of the workpiece to be assembled.

[0082] In this embodiment, all three sensing mechanisms adopt Figure 2 As shown, the height detection component based on the through-beam sensor determines the specific specifications of the workpiece to be assembled by detecting the workpiece height.

[0083] Specifically, such as Figure 7 As shown, the first sensing mechanism 301 includes: a first through-beam sensor 301a and a second through-beam sensor 301b; the second sensing mechanism includes: a third through-beam sensor 302a and a fourth through-beam sensor 302b; the third sensing mechanism includes: a fifth through-beam sensor 303a and a sixth through-beam sensor 303b.

[0084] The first through-beam sensor 301a is positioned at a height lower than the first workpiece height L1; the second through-beam sensor 301b is positioned at a height higher than the first workpiece height L2. The third through-beam sensor 302a is positioned between the first workpiece height L1 and the second workpiece height L2; the fourth through-beam sensor 302b is positioned between the second workpiece height L2 and the third workpiece height L3. The fifth through-beam sensor 303a is positioned at a height lower than the first workpiece height L1; the sixth through-beam sensor 303b is positioned between the second workpiece height L2 and the third workpiece height L3.

[0085] Please continue reading. Figure 7 It can be understood that the signals generated by workpieces of different specifications are as follows: First, when the workpiece passes the first sensing mechanism, if the first photoelectric sensor has a detection signal and the second photoelectric sensor does not, it can be determined that the workpiece belongs to the first target specification with the lowest workpiece height. Second, when the workpiece continues to move to the second sensing mechanism, if the third photoelectric sensor has a detection signal and the fourth photoelectric sensor does not, it can be determined that the workpiece belongs to the second target specification with a medium workpiece height. Finally, when the workpiece continues to move to the third sensing mechanism, if both the fifth and sixth photoelectric sensors have detection signals, it can be determined that the workpiece matches the third target specification.

[0086] The first blocking mechanism 401, the second blocking mechanism 402, and the third blocking mechanism 403 are respectively paired with the first lifting beam assembly mechanism 201, the second lifting beam assembly mechanism 202, and the third lifting beam assembly mechanism 203, and are used to keep the workpiece to be assembled at the assembly station and prevent other workpieces to be assembled from entering. All three blocking mechanisms can adopt the following... Figure 3 The structure shown achieves control over the movement of the workpiece to be assembled through the cooperation of the first blocking component and the second blocking component.

[0087] In actual use, multiple plastic buckets, which may have the same or different specifications, will enter the conveyor line in sequence and move forward along the transmission direction under the drive of the conveyor line. For example... Figure 8 As shown, when one of the plastic buckets passes the first sensing mechanism, the controller can determine whether the plastic bucket is of the first target specification based on the detection signal provided by the first sensing mechanism (S801).

[0088] When the plastic bucket body is determined to be the first target specification, the first blocking mechanism is controlled to stop the plastic bucket body at the first assembly station and prevent other plastic bucket bodies from entering the first assembly station (S802). Subsequently, the first lifting beam assembly mechanism automatically assembles the lifting beam of the plastic bucket body stopped at the first assembly station (S803). After the lifting beam assembly is completed, the control mechanism controls the first blocking mechanism to release the plastic bucket of the first target specification, which can then continue to move along the workpiece outlet driven by the conveyor line (S804).

[0089] If it is determined that the plastic bucket body is not the first target specification, the first blocking mechanism is controlled to maintain the default recycling state, so that it passes through the first assembly station and continues to move to the second sensing mechanism for detection (S805).

[0090] Similar to the operation and control method of the first sensing mechanism mentioned above, the controller also determines whether the plastic bucket body is the second target specification based on the detection signal provided by the second sensing mechanism (S806).

[0091] When the plastic bucket body is determined to be the second target specification, the second blocking mechanism is controlled to stop the plastic bucket body at the second assembly station and prevent other plastic bucket bodies from entering the second assembly station (S807). Subsequently, the second lifting beam assembly mechanism automatically assembles the lifting beam of the plastic bucket body stopped at the second assembly station (S808). After the lifting beam assembly is completed, the second blocking mechanism is controlled to release the plastic bucket of the second target specification, which can continue to move along the workpiece outlet under the drive of the conveyor line (S809).

[0092] If it is determined that the plastic barrel body is not the second target specification, the second blocking mechanism is controlled to maintain the default recycling state, so that it can continue to move to the second sensing mechanism for detection through the second assembly station (S810).

[0093] Furthermore, the controller also determines whether the plastic bucket body conforms to the third target specification (S811) based on the detection signal provided by the third sensing mechanism.

[0094] When the plastic bucket body is determined to be the third target specification, the third blocking mechanism is controlled to stop the plastic bucket body at the third assembly station and prevent other plastic bucket bodies from entering the third assembly station (S812). Subsequently, the third lifting beam assembly mechanism automatically assembles the lifting beam of the plastic bucket body stopped at the third assembly station (S813). After the lifting beam assembly is completed, the third blocking mechanism is controlled to release the plastic bucket of the third target specification, which can continue to move along the workpiece exit under the drive of the conveyor line (S814).

[0095] If it is determined that the plastic barrel body is not the third target specification, the third blocking mechanism is controlled to maintain the default retraction state, so that it can continue to move to the workpiece outlet through the third assembly station (S815).

[0096] For each plastic bucket, the following procedure is performed: Figure 8 The operation shown enables the automatic sorting of plastic buckets of different specifications, allowing them to be placed at appropriate assembly stations where the matching lifting beam assembly mechanism completes the lifting beam assembly process. Furthermore, since each sensor can identify different specifications of plastic buckets, those with the first target specification and those with the second target specification, after completing the lifting beam assembly, can smoothly pass through subsequent and third assembly stations and be output from the workpiece exit based on the aforementioned control logic, without requiring additional identification and confirmation of whether the lifting beam has been installed on the plastic bucket.

[0097] It should be noted that the embodiments in this application are described using three different assembly stations as an example. However, those skilled in the art can adjust, replace, or change one or more components and mechanisms of the above-mentioned automatic beam assembly device based on the control logic disclosed in the above embodiments, according to actual needs, without making specific limitations here.

[0098] The above description, in conjunction with specific / preferred embodiments, provides a further detailed explanation of this application and should not be construed as limiting the specific implementation of this application to these descriptions. Those skilled in the art can make various modifications and improvements without departing from the concept of this application, and all of these fall within the scope of protection of this application.
