Description

Technical Field

[0001] The invention belongs to the technical field of electroplating, and in particular relates to a sealing device, a container and a workpiece processing system. Background Art

[0002] At present, in the fields of cleaning, electroplating, coating, etc., different containers are used to hold different liquids to form the required process flow to complete the cleaning, electroplating, coating and other processes of the workpiece. For example, if the workpiece is to be degreased-washed-pickled-washed-plated-washed in sequence, six containers need to be set up in sequence, namely the first container, the second container, the third container, the fourth container, the fifth container and the sixth container.

[0003] In addition to the above-mentioned multiple containers, conventional workpiece processing equipment also includes a sliding mechanism arranged directly above the container and a lifting mechanism installed on the sliding mechanism. During the workpiece processing process, the workpiece is first installed on the lifting mechanism, and the lifting mechanism first drives the workpiece to move downward so that the workpiece extends into the degreasing solution in the first container. After the degreasing process is completed, the lifting mechanism drives the workpiece to move upward and is taken out of the first container; thereafter, the sliding mechanism drives the lifting mechanism and the workpiece to move synchronously so that the workpiece moves from directly above the first container to directly above the second container, and then repeats the above-mentioned lifting mechanism driving the workpiece to move downward first, and the workpiece enters the washing solution in the second container. After the washing process is completed, the lifting mechanism takes the workpiece out of the second container again, and the sliding mechanism moves again so that the lifting mechanism and the workpiece are directly above the third container, and so on, gradually completing the process of the workpiece in the six containers.

[0004] If the sliding mechanism only moves the workpiece in the horizontal direction, a connecting hole needs to be opened on the wall of each container. The workpiece passes through the connecting hole when moving from the rear container to the front container. The inner cavity of each container is always connected to the connecting hole. The solution in the inner cavity of the container will continuously flow out through the connecting hole, causing the liquid level in the container to drop rapidly, affecting the processing effect of subsequent batches of workpieces. Summary of the invention

[0029] And a workpiece processing system, comprising at least one container as described above.

[0030] Optionally, the workpiece processing system further comprises at least one fixture that can pass through the sealed channel, the fixture being provided with a placement cavity for accommodating at least one workpiece to be processed, and the placement cavity being communicated with the inner cavity of the container where the fixture is located;

[0031] The sealing device L2 i It is the distance between the two outer end surfaces of any one of the jigs along the first direction.

[0032] The technical solution of the present invention has the following advantages:

[0033] 1. The sealing device provided by the present invention comprises at least one sealing mechanism, wherein the sealing mechanism comprises a first driving mechanism arranged in the sealing channel and dividing the sealing channel into a sliding channel and a first area; and at least two first sealing components arranged on the first driving mechanism at intervals and respectively distributed in the sliding channel and the first area; the first sealing component is driven by the first driving mechanism to perform a closed loop cyclic movement along a first direction, and at least two of the first sealing components are respectively slidably connected to the inner wall of the sealing channel where the sliding channel and the first area are located; along the first direction, the length of any of the sliding channels is L0 i , the length of any workpiece to be processed is L2 i The path length between any two adjacent first sealing components is L1 i ; said L1 i With L0 i 、L2 i Satisfy between:

[0035] In this sealing device, when a plurality of workpieces to be processed or the jigs where the workpieces are located continuously slide through the sliding channel along the first direction, the sealing channel is in a relatively static state relative to the jigs where the workpieces are located. Since at least two first sealing components of the sealing mechanism are respectively sealingly slidably connected with the inner side wall of the sliding channel and the inner side wall of the sealing channel where the first area is located, the workpieces to be processed or the jigs where the workpieces are located can slide and seal the sliding channel with the cooperation of at least two first sealing components, thereby preventing the solution from flowing out from the inside to the outside and reducing the outflow of the solution in the container. Since the first sealing component of the first area is sealed and slidably connected with the inner side wall of the sliding channel and the inner side wall of the sealing channel where the first area is located, the sliding channel can be slidably sealed. The component can be slid sealingly on the inner wall surface of the sealing channel, so that there is a very small gap or no gap between the outer side of the sealing mechanism and the inner wall surface of the sealing channel, which can block the solution in the first area between the outer side wall of the sealing mechanism and the inner wall of the sealing channel. Therefore, with the cooperation of at least two first sealing components, most of the solution in the sealing channel is blocked in the inner cavity of the container, reducing the outflow of the solution in the container through the inlet end or the inlet end of the sealing channel, slowing down the speed at which the liquid level of the solution in the container drops, making it easier to maintain the liquid level in the container, and having less impact on the processing of batch workpieces.

[0036] 2. The sealing device provided by the present invention has one end of the first sealing component hinged on the first driving mechanism and the other end extending outward; the projection line of the straight line extending in the first direction onto the horizontal plane is used as the reference line; the first sealing component rotates under the driving force of the outside, so that the first sealing component can switch between a vertical state perpendicular to the first driving mechanism in the sliding channel and an inclined state inclined relative to the first driving mechanism in the first area; the outer wall of the first sealing component is sealingly slidably connected with the inner wall of the corresponding sealing channel. The setting of this structure is through the slidable contact between the first sealing component of the outer wall of the sealing mechanism and the inner wall surface of the sealing channel, so that the gap in the first area between the outer wall surface of the sealing mechanism and the inner wall surface of the sealing channel is very small or has no gap, which can play a blocking role on the solution in the first area, so that under the cooperation of the sliding channel and at least two first sealing components in the first area and the sealing channel, most of the solution in the sealing channel is blocked in the inner cavity of the container; and the first sealing component is set to be tiltable, which can effectively reduce the size of the sealing channel.

[0037] 3. The sealing device provided by the present invention, wherein the first spacing of the first area in the direction from the sliding channel to the first area is less than the length of the first sealing component; the sealing mechanism further comprises at least one biasing member provided on the first driving mechanism and applying a biasing force to the first sealing component in the direction opposite to the first driving mechanism; the first sealing component is in the vertical state due to the biasing force, and is in the inclined state due to the extrusion force of the inner wall surface of the sealing channel where the first area is located in the first area. The setting of the biasing member can make the first sealing component in the first area be extruded by the inner wall of the sealing channel to be inclined and be in sealing and sliding connection with the inner wall of the sealing channel, and at the same time, when the first sealing component moves from the first area to the sliding channel, it is perpendicular to the first driving mechanism due to the biasing force of the biasing member, and the first sealing component of the sliding channel can be sealed and abutted by the setting of the elastic member, and at the same time, the first sealing component of the first area can be deflected and slide and abut with the inner wall or bottom wall of the sealing channel to achieve sealing, thereby reducing the friction between the first sealing component and the inner wall or bottom wall of the sealing channel.

[0038] 4. The workpiece processing system provided by the present invention comprises at least two containers, wherein adjacent walls of at least two adjacent containers are respectively provided with a sealing channel, and the two adjacent sealing channels are arranged separately.

[0039] In the workpiece handling system of this structure, when several workpieces or the fixtures where the workpieces are located continuously move in the container and enter the sliding channel in the sealed channel, due to L1 i With L0 i 、L2 i The above relationship is satisfied, and at least one first sealing component is provided in each sliding channel to seal and slide in the sliding channel, so that the inner cavity of the sliding channel is sealed and separated from the inner cavity of the container in which the sealing channel is located, thereby preventing the solution in the inner cavity of the container from continuously entering the sliding channel; at the same time, the first sealing component of the first area slides and abuts against the inner wall surface of the sealing channel, so that there is a very small gap or a gap-free fit between the outer wall of the sealing mechanism and the inner wall of the sealing channel, which can block the solution between the outer wall of the sealing mechanism and the inner wall of the sealing channel, thereby reducing the amplitude of the reduction in the liquid level of the solution in the inner cavity of the container, and then only moving the fixture in one direction can continuously drive the workpiece to be processed to move, so that the workpiece can be transferred out of one container and into the next container while the liquid level is reduced very little, and the workpiece is continuously processed in different processes, thereby simplifying the workpiece processing process and facilitating subsequent batch processing of workpieces.

[0051] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Example 1

[0053] This embodiment provides a sealing device for sealing a container 3 disposed on at least one side wall and along a first direction (such as Figure 1 The sealing channel 4 extending from left to right in the horizontal direction as shown in FIG. 1 is sealed, and includes at least one sealing mechanism, such as Figure 1 As shown, two sealing mechanisms are provided, and the two sealing mechanisms are symmetrically arranged on both sides of the sealing channel 4; Figure 2 As shown, there is one sealing mechanism, and one sealing mechanism is arranged at the bottom of the sealing channel 4.

[0054] As for the sealing mechanism, the sealing mechanism includes a first driving mechanism 2 arranged in the sealing channel 4 and dividing it into the sliding channel 7 and the first area 8; and at least two first sealing components 1 arranged on the first driving mechanism 2 at intervals and respectively distributed in the sliding channel 7 and the first area 8; the first sealing component 1 is driven by the first driving mechanism 2 to perform a closed loop cyclic movement along the first direction, and at least two first sealing components 1 are respectively slidably connected to the inner wall of the sealing channel 4 where the sliding channel 7 and the first area 8 are located; along the first direction, the length of any sliding channel 7 is L0 i , the length of any workpiece to be processed is L2 i , the path length between any two adjacent first sealing components 1 is L1 i ; L1 i With L0 i 、L2 i Satisfy between:

[0055] L0 min ≥L1 max , L1 min ≥L2 max , where L1 max For all L1 i The maximum value in L2 max For all L2 i The maximum value in L0 min For all L0 i , and i is a natural number greater than or equal to 1.

[0056] In this sealing device, when a plurality of workpieces or jigs where the workpieces are located continuously slide through the sliding channel 7 along the first direction, the sealing channel 4 is in a relatively static state relative to the workpieces or the jigs where the workpieces are located. Since at least two first sealing components of the sealing mechanism in the sliding channel 7 are respectively sealed and slidably connected with the inner side wall of the sliding channel and the inner side wall of the sealing channel where the first area is located, the workpieces to be processed or the jigs where the workpieces are located slide and seal the sliding channel 7 with the cooperation of at least two first sealing components 1 and the inner wall of the sealing channel 4, thereby preventing the solution from flowing out from the inside to the outside and reducing the outflow of the solution in the container 3. Since the two first sealing components 1 in the first area 8 can slide in a sealing manner On the inner wall surface of the sealing channel 4, there is a very small gap or no gap between the outer side of the sealing mechanism and the inner wall surface of the sealing channel 4, which can block the solution in the first area 8 between the outer wall of the sealing mechanism and the inner wall of the sealing channel 4. Therefore, with the cooperation of at least two first sealing components 1 of the sliding channel 7 and the first area 8 and the inner wall of the sealing channel 4, most of the solution in the sealing channel 4 is blocked in the inner cavity of the container 3, reducing the outflow of the solution in the container 3 through the inlet end or the inlet end of the sealing channel 4, slowing down the speed at which the liquid level of the solution in the container 3 drops, making it easier to maintain the liquid level in the container 3, and having less impact on the processing of batch workpieces.

[0057] For the first sealing component 1, if Figure 1As shown, the sliding channel 7 and the first area 8 are both provided with two first sealing components 1, one end of the first sealing component 1 is hinged on the first driving mechanism 2, and the other end extends outward; a projection line of a straight line extending in the first direction onto a horizontal plane is used as a reference line; the first sealing component 1 is rotated by the driving force of the first driving mechanism 2, so that the first sealing component 1 can be switched between a vertical state perpendicular to the first driving mechanism 2 in the sliding channel 7 and an inclined state inclined relative to the first driving mechanism 2 in the first area 8; the outer wall of the first sealing component 1 is sealingly slidably connected to the inner wall of the corresponding sealing channel 4; in order to enable the first sealing component 1 to be in a vertical state perpendicular to the first driving mechanism 2 in the sliding channel 7, and in the first area The first region 8 can be in an inclined state due to the squeezing of the inner wall surface of the sealing channel 4, the first spacing d of the first region 8 in the direction from the sliding channel 7 to the first region 8 is less than the length L of the first sealing component 1, and the sealing mechanism also includes at least one biasing member (not shown) provided on the first driving mechanism 2 and applying a biasing force to the first sealing component 1 in the direction opposite to the first driving mechanism 2, the first sealing component 1 is in a vertical state due to the biasing force, and is in an inclined state due to the squeezing force of the inner wall surface of the sealing channel 4 where the first region 8 is located in the first region 8; specifically, one end of the first sealing component 1 is hinged to the first driving mechanism 2 through a hinge; optionally, the biasing member is a torsion spring or other commonly used biasing members; the first sealing component 1 is in the shape of a plate. As an alternative embodiment, the first sealing component 1 can also adopt a retractable structure, the first sealing component 1 does not tilt in the first region 8, the first sealing component 1 on the side of the sliding channel 7 is always perpendicular to the first driving mechanism 2, and the extended end of the first sealing component 1 is retracted in the first region 8 and sealed against the inner wall of the sealing channel 4. As an option, the lengths of the sliding channel 7 and the first area 8 may be equal, or may be as follows: Figure 1 and Figure 2 The length of the first area 8 shown is smaller than the length of the sliding channel 7 , and is not specifically limited, as long as the first sealing component 1 can achieve sealing in the sliding channel 7 and the first area 8 .

[0058] For the first driving mechanism 2, the first driving mechanism 2 includes a transmission belt 21 in a closed loop and a driving assembly 22 for driving the transmission belt 21 to move in a circular motion. One end of the first sealing component 1 is arranged on the transmission belt 21, and the other end extends outward. That is, the first sealing component 1 moves back and forth from the sliding channel 7 to the first area 8 under the driving action of the transmission belt 21. Specifically, the driving assembly 22 is an existing belt drive wheel structure, which mainly includes a driving wheel composed of a driving wheel and a driven wheel and a motor connected to the driving wheel to drive the driving wheel to rotate, and no specific limitation or description is made. Since the first sealing component 1 is arranged on the first driving mechanism 2, and the first driving mechanism 2 includes a closed-loop transmission belt 21, the closed-loop transmission belt 21 is composed of two opposite straight segments and two opposite arc segments, and the distance L1 between two adjacent first sealing components 1 at the front and rear ends in the sliding channel is i or the distance L1 between two adjacent first sealing components 1 at the front and rear ends of the first region. i represents the length of the middle part of the straight section of the conveyor belt 21; and the length L1 of the path between two adjacent first sealing components 1, one of which is in the sliding channel 7 and the other in the first area 8 i It represents the sum of the length of the remaining parts of two straight line segments and the length of an arc segment.

[0059] For the sliding channel 7, if Figure 1 As shown, the length L0 of the sliding channel 7 i Refers to the distance between the center of the driving wheel and the center of the driven wheel.

[0060] like Figure 1As shown, the sealing mechanisms are arranged on both sides of the sealing channel 4, and there are two sealing mechanisms, which are symmetrically arranged in the sealing channel 4; the square area enclosed by two groups of four first sealing components 1 between the walls facing each other of the first driving mechanisms 2 in the two sealing mechanisms forms a sliding channel 7, and the walls facing each other form first areas 8 with the inner walls of the corresponding sealing channels 4 respectively; the sliding channel 7 and the first areas 8 are arranged side by side in the horizontal direction; when the first sealing components 1 of the two sealing mechanisms slide in the sliding channel 7, the end faces of the two symmetrical first sealing components 1 facing each other are sealed and abutted. As an option, the sealing mechanism can also be provided with three, four, five, etc., which are not specifically limited or described. When the number is three, four, five, etc., which is greater than two, the sealing mechanisms are arranged at intervals along the first direction of the sealing channel 4, and can be all arranged on one inner side wall of the sealing channel 4, or can be symmetrically arranged on two inner side walls, or can be arranged alternately in the above two ways, that is, there are both symmetrical arrangements and only one inner side wall arrangements, such as two sealing mechanisms are symmetrically arranged inside the front end of the sealing channel 4, and only one side wall is arranged at the rear end of the sealing channel 4 where the two sealing mechanisms are symmetrically arranged, which are not specifically limited or described. The sliding channel 7 and the first area 8 are arranged side by side in the horizontal direction; when the first sealing component 1 moves in the sliding channel 7, the vertical outer side end face of the first sealing component 1 opposite to the first driving mechanism 2 is sealed and slidably connected to the vertical inner wall of one side of the sealing channel 4 where the sliding channel 7 is located; and when moving in the first area 8, the vertical outer side end face of the first sealing component 1 is sealed and slidably connected to the vertical inner wall of the other side of the sealing channel 4 where the first area 8 is located. The two first sealing components 1 of the sliding channel 7 seal and separate the two adjacent workpieces of the sealing channel 4, and the first sealing component 1 of the first area 8 is sealingly slidably connected to the inner side wall of the sealing channel 4, so that the workpiece can slide through the sealing channel 4 in a sealed manner. Multiple sealing mechanisms are arranged in the sealing channel 4 to form multiple seals for the sealing channel 4, further strengthen the sealing of the sealing channel 4, reduce the amount of solution in the container 3 flowing out through the sealing channel 4, and ensure that the liquid level of the solution in the container 3 maintains a required height.

[0061] As a replaceable embodiment, only one sealing mechanism is provided, which is arranged on an inner wall of the sealing channel 4. The sealing mechanism includes two first sealing components 1, one of the two first sealing components 1 is vertically arranged in the sliding channel 7, and the other is obliquely arranged in the first area 8. A side of a first sealing component 1 in the sliding channel 7 away from the sealing mechanism is sealingly slidably abutted against the other side wall of the sealing channel 4, and a side of a first sealing component 1 in the first area away from the sealing mechanism is slidingly sealingly abutted against a side wall of the sealing channel 4; of course, the number of first sealing components 1 can also be set to three, four, five, etc.

[0062] Example 2

[0063] The difference from the above-mentioned embodiment 1 is that the sealing mechanism is arranged at a different position in the sealing channel 4, such as Figure 2 As shown, the sealing mechanism is arranged at the bottom of the sealing channel 4, at this time, the sliding channel 7 and the first area 8 are arranged side by side in the vertical direction, and the sliding channel 7 is located above the first area 8; when the first sealing component 1 moves in the sliding channel 7, its two vertical outer walls are respectively sealed and slidably connected with the two vertical inner walls of the sealing channel 4 where the sliding channel 7 is located; and when moving in the first area 8, the bottom surface of the first sealing component 1 is sealed and slidably connected with the bottom surface of the sealing channel 4 where the first area 8 is located. The vertical length of the first sealing component 1 is higher than the height of the liquid level in the container 3, so that when the workpiece passes through the sealing channel 4 in a sealed manner, the first sealing component 1 seals the inlet and outlet ends of the sealing channel 4, so that the inner cavity of the sealing channel 4 is isolated from the inner cavity of the container.

[0064] Example 3

[0065] A container of this embodiment, such as Figure 1 and Figure 2 As shown, the container 3 has an inner cavity, at least one side wall is provided with a sealing channel 4 connected to the inner cavity and extending along a first direction; and the sealing device of the above-mentioned embodiment 1 or embodiment 2 is provided in the sealing channel 4. Optionally, both side walls of the container 3 are provided with a sealing channel 4 connected to the inner cavity and extending along the first direction; specifically, part of the sealing channel 4 can be formed on the wall of the container 3, and part of the sealing channel 4 can be provided on the box body (not shown). The specific setting method can be determined according to actual needs. Optimally, the lengths of all the sealing channels 4 are the same, but of course they can also be different.

[0066] Since the container of this embodiment adopts the sealing device of the above-mentioned embodiments 1 and 2, the amount of solution in the container 3 flowing out through the sealing channel 4 is small, and the speed at which the liquid level in the container 3 drops is slow, which has little impact on the processing of subsequent batch workpieces.

[0067] Example 4

[0068] A workpiece processing system of this embodiment, such as Figure 1 As shown, it includes at least one container 3 of embodiment 3. The workpiece or any one of the jig and container 3 where the workpiece is located is driven by the driving mechanism to pass through any sliding channel 7.

[0069] In this embodiment, taking the first implementation mode of the sealing device in Embodiment 1 as an example, the length of the sliding channel 7 is the distance between the center of a driving wheel at the front end and the center of a driving wheel at the rear end in the first direction.

[0070] For the workpieces to be processed, a jig 5 can be arranged in the slide channel 7. The jig 5 is provided with a placement cavity for accommodating at least one workpiece to be processed, and the placement cavity is connected to the inner cavity of the container 3 where the jig 5 is located; thus, batches of workpieces to be processed can be placed in the jig 5 at one time. i is the distance between the two outer end surfaces of any fixture 5 along the first direction.

[0071] In the workpiece processing device of this embodiment, the workpiece to be processed is placed in the fixture 5; when several fixtures 5 are continuously moved in the container 3 and enter the sliding channel 7 in the sealing channel 4, due to L1 i With L0 i 、L2 i The above relationship is satisfied, and at least one first sealing component 1 is provided in each sliding channel 7 to slide sealingly in the sliding channel 7, so that the inner cavity of the sliding channel 7 is sealed and separated from the inner cavity of the container 3 where the sealing channel 4 is located, thereby preventing the solution in the inner cavity of the container 3 from continuously entering the sliding channel 7; at the same time, the outer wall of the sealing mechanism, that is, the two first sealing components 1 in the first area 8, slide against the inner wall surface of the sealing channel 4, so that there is a very small gap or no gap between the outer wall of the sealing mechanism and the inner wall of the sealing channel 4, which can block the solution between the outer wall of the sealing mechanism and the inner wall of the sealing channel 4, thereby reducing the amplitude of the liquid level reduction of the solution in the inner cavity of the container 3 through the cooperation of the sliding channel 7 and at least two first sealing components 1 in the first area 8, and then only moving the fixture 5 in one direction can continuously drive the workpiece to be processed to move, so that the workpiece is transferred out of one container 3 and into the next container 3 while the liquid level is reduced very little, and the workpiece is continuously processed in different processes, which simplifies the workpiece processing process and facilitates subsequent batch processing of workpieces.

[0072] Optimally, there are multiple containers 3, and the multiple containers 3 can be arranged linearly in sequence; or there are at least three containers 3, and all containers 3 are arranged in a ring.

[0073] A sealing channel 4 is respectively provided on the adjacent walls of two adjacent containers 3, and the sealing channels 4 of the two adjacent containers 3 are spaced apart. The sliding channel 7 in each container 3 is provided with the sealing device in Example 1, and L1 i With L0 i 、L2 iThe above relationship is satisfied. When workpieces to be processed continuously enter the starting end container 1 and continuously move in the direction from the rear container to the front container, it is only necessary to move the fixture 5 or the container 3 in one direction to continuously drive the workpiece to move, so that the liquid level is slightly reduced and the solutions in the two adjacent containers 3 will not mix. The workpiece is transferred from the rear container 3 to the front container 3, and different processes are continuously performed on the workpiece, which simplifies the workpiece processing process and facilitates subsequent batch processing of workpieces.

[0074] Example 5

[0075] The workpiece processing system of this embodiment, taking the implementation method of the sealing device in Example 2 as an example, Figure 2 As shown, the length of the sliding channel 7 is the same as the length of the sealing channel 4 .

[0076] In the workpiece processing device of this embodiment, the workpiece to be processed is placed in the fixture 5; when several fixtures 5 are continuously moved in the container 3 and enter the sliding channel 7 in the sealing channel 4, due to L1 i With L0 i 、L2 i The above relationship is satisfied. In each sliding channel 7, there is at least one first sealing component 1 that slides sealingly in the sliding channel 7, so that the inner cavity of the sliding channel 7 is sealed and separated from the inner cavity of the container 3 where the sealing channel 4 is located, and the solution in the inner cavity of the container 3 is blocked from continuously entering the sliding channel 7. At the same time, the bottom of the sealing mechanism, that is, the two first sealing components 1 of the first area 8, slide against the bottom wall of the sealing channel 4, so that there is a very small gap or no gap between the bottom of the sealing mechanism and the bottom wall of the sealing channel 4, and it can also play a blocking role for the solution between the bottom of the sealing mechanism and the bottom wall of the sealing channel 4, so that the liquid level of the solution in the inner cavity of the container 3 is reduced by the cooperation of the first sealing component 1 in the sliding channel 7 and at least two first sealing components 1 in the first area 8. Then, only the jig 5 needs to be moved in one direction to continuously drive the workpiece to be processed to move, so that the workpiece is transferred out of one container 3 and enters the next container 3 while the liquid level is reduced very little, and the workpiece is continuously processed in different processes, which simplifies the workpiece processing process and facilitates subsequent batch processing of workpieces.

[0077] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
