[0034] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts shall fall within the scope of protection of the present application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0035] Refer to Figure 1a , Figure 1a It is a schematic structural diagram of the first embodiment of the sheet guiding system of the present application. The sheet guiding system 100 includes a first sheet guiding station 10, a second sheet guiding station 20, a handling mechanism (not shown in the figure), and a buffer mechanism 102. The first sheet guiding station 10 is used to place a first container. The second sheet guiding station 20 is used to place a second container. The handling mechanism is used to transfer sheet materials between the first container and the second container. The buffer mechanism 102 is used to split or combine the sheet materials in the first container. The first container has a plurality of carrying units 101, and the buffer mechanism 102 can jointly form an access unit 103 with the carrying units 101 for loading the sheet materials obtained by splitting the combined state in the carrying units 101.

[0036] In addition, Figure 1aThe first container, the second container, and the buffer mechanism shown in the figure are all composed of multiple minimum rectangles. The minimum rectangle represents a specific number of sheet loading amounts. When the minimum rectangle is white, it indicates an empty load, and when the minimum rectangle has other filling colors, it indicates that sheets are loaded. In the figure, the number of the first containers is 2, which are the first wafer carrier 11 and the second wafer carrier 12 respectively. Taking the first wafer carrier 11 as an example for specific description: The first wafer carrier 11 is composed of 32 minimum rectangles, and 2 buffer mechanisms are configured on the right side. Among them, every 4 minimum rectangles distributed in a cross shape represent 1 loading unit. Then, there are 8 loading units in the first wafer carrier 11 from top to bottom. The 2 buffer mechanisms in the figure correspond to the 1st loading unit and the 3rd loading unit respectively.

[0037] Refer to Figure 1b , Figure 1b FIG. is a schematic structural diagram of the second implementation manner of the wafer guiding system provided by the present application. Taking the cooperation of 1 loading unit and 1 buffer mechanism as an example for illustration, 4 minimum rectangles on the left side in the figure represent 1 loading unit. Taking the example that a single minimum rectangle represents a sheet loading amount of 60 sheets, then this loading unit can load 240 sheets, and the buffer mechanism on the right side includes 2 minimum rectangles, that is, the loading amount is 120.

[0038] Among them, each tooth groove for loading sheets in the loading unit can accommodate 2 sheets, and each tooth groove for loading sheets in the buffer mechanism and the second container can accommodate 1 sheet.

[0039] Refer to Figure 1c , Figure 1c FIG. is a schematic structural diagram of the third implementation manner of the wafer guiding system provided by the present application. The upper half of the figure shows that the loading unit is fully loaded with 240 sheets, and the sheets are stored in pairs in 120 tooth grooves; the lower half of the figure shows that after the sheets in the loading unit in the combined state are split, 120 of the sheets are still stored individually in 120 tooth grooves, and the other 120 sheets are stored individually in the tooth grooves of the buffer mechanism.

[0040] Refer to Figure 1d , Figure 1d FIG. is a schematic structural diagram of the fourth implementation manner of the wafer guiding system provided by the present application. The upper half of the figure shows that the access unit composed of the loading unit and the buffer mechanism stores 240 sheets transferred from the second container individually; the lower half of the figure shows that the sheets in the access unit are combined, so that 120 sheets in the buffer mechanism and 120 sheets in the loading unit are stored in pairs in 120 tooth grooves.

[0041] Specifically, the first container is a wafer boat for carrying wafers. Each wafer boat includes a plurality of carrying units 101. Each carrying unit 101 specifically includes a plurality of equally-spaced grooves (not shown in the figure). Each groove can carry a set of two wafers in the wafer-bonded state. In this embodiment, each wafer boat includes K carrying units 101, each carrying unit 101 includes N grooves, and each groove can carry 2 wafers, that is, each carrying unit 101 can carry 2N wafers. A wafer guiding system 100 can include one or more first containers. In Figure 1a the illustrated embodiment, the number of first containers, i.e., wafer boats, is two, namely a first wafer boat 11 and a second wafer boat 12. The two wafer boats are arranged side by side, and the number of carrying units 101 of the two wafer boats is the same.

[0042] The second container is a flower basket (not labeled). The flower basket is used for carrying wafers. According to the state of the wafers carried, the flower basket is divided into a dry flower basket 21 and a wet flower basket 22. Among them, the dry flower basket 21 is used for carrying the processed wafers (clinker) transferred from the wafer boat, and the wet flower basket 22 is used for carrying the wafers to be processed and to be transferred to the wafer boat (raw material). The dry flower basket 21 and the wet flower basket 22 have the same structure and can carry the same number of wafers. In this embodiment, a flower basket can specifically carry 2N wafers.

[0043] The buffer mechanism 102 can specifically include a plurality of buffer grooves (not shown in the figure). Each buffer groove can carry one wafer. The buffer mechanism 102 can be correspondingly arranged on one side of the carrying unit 101 of the wafer boat. The buffer mechanism 102 and the corresponding carrying unit 101 together constitute an access unit 103.

[0044] In one embodiment, the number of buffer mechanisms 102 is one. At this time, the speed at which the buffer mechanism splits and merges the wafers in the carrying unit 101 matches the speed at which the handling mechanism transfers the wafers between the wafer boat and the flower basket.

[0045] In one embodiment, the number of buffer mechanisms 102 is multiple. When the number of wafer boats is one, one wafer boat corresponds to multiple buffer mechanisms 102; when the number of wafer boats is multiple, each wafer boat corresponds to one or more buffer mechanisms 102. In this embodiment, each of the two wafer boats is correspondingly provided with two buffer mechanisms 102. The two buffer mechanisms 102 respectively correspond to two carrying units 101 arranged at intervals in each wafer boat. At the same time, the buffer mechanism 102 can move to switch the corresponding different carrying units 101. Keeping an interval between the carrying units 101 corresponding to different buffer mechanisms 102 can provide sufficient space for the operation of the buffer mechanism 102, thereby avoiding structural or operational interference between adjacent buffer mechanisms 102.

[0046] In another embodiment, the carrier units 101 corresponding to the multiple buffer mechanisms 102 may also be arranged adjacent to each other.

[0047] In another embodiment, the first container is provided with a first working area and a second working area. The first working area and the second working area respectively include a plurality of continuously distributed carrier units; the buffer mechanisms configured in the first working area and the buffer mechanisms configured in the second working area have staggered working states. As shown in Figure 1a , if every 4 smallest rectangles distributed in a cross shape represent 1 carrier unit, then there are 8 carrier units from top to bottom in the first carrier boat 11. Among them, the upper 4 carrier units can be divided into the first working area, and the lower 4 carrier units can be divided into the second working area; 1-2 buffer mechanisms can be configured in each working area. In this way, the handling mechanism can switch the working areas between the first working area and the second working area according to different handling directions. The buffer mechanisms within each working area have the same working state, which can realize the segmented control of the buffer mechanisms. Multiple buffer mechanisms in the same segment can improve fault tolerance and effectively cope with local failures. At the same time, it can simplify the overall automation scheduling complexity of the wafer guiding system and facilitate flexible adjustment of the working area partition according to the change of production capacity rhythm.

[0048] The handling mechanism is used to transfer the wafers between the first container and the second container. Specifically, the handling mechanism is used to transfer the wafers between the access unit 103 and the second container. The handling mechanism can transfer the processed wafers from the carrier boat and the buffer mechanism 102 to the dry flower basket 21, and can also transfer the wafers to be processed from the wet flower basket 22 to the carrier boat and the buffer mechanism 102. Optionally, the handling mechanism is arranged above the first container and the second container to make full use of the space to avoid affecting the carrier boat and the flower basket during the handling process, and can also make the arrangement of the first container and the second container more compact, saving the floor area of the wafer guiding system and saving the production site.

[0049] In one embodiment, the handling mechanism may be a suction cup manipulator.

[0050] In one embodiment, the handling mechanism may be an overhead crane, and the overhead crane can suck multiple wafers at one time with a suction cup. Compared with the manipulator, the overhead crane has lower procurement and maintenance costs, and is more suitable for transferring a large number of wafers at one time, and can well meet the requirements of the increasing production capacity rhythm.

[0051] Refer to Figure 2 , Figure 2 is a schematic flow chart of an embodiment of the wafer guiding method of the present application. This wafer guiding method is applied to the wafer guiding system 100. This method includes two working states, the first working state S1 and the second working state S2. Among them, the first working state S1 includes the following steps:

[0052] S110: Split the sheets in the assembled state in the carrier unit 101, store the redundant sheets in the buffer mechanism 102, and let the carrier unit 101 and the buffer mechanism 102 together form an access unit 103.

[0053] Specifically, step S110 includes: The buffer mechanism 102 includes a lifting member. Use the lifting member to push out one of the two sheets in the assembled state in each tooth groove of one or more carrier units 101. The sheets in each tooth groove are split. At this time, the empty buffer mechanism 102 can move to one side of the corresponding carrier unit 101, and the two are arranged side by side. Then transfer all the pushed-out sheets from the lifting member to the buffer tooth grooves of the corresponding buffer mechanism 102, that is, half of the sheets in the carrier unit 101 are transferred to the buffer mechanism 102. At this time, the number of sheets carried in the buffer mechanism 102 is the same as the number of sheets carried in its corresponding carrier unit 101. The buffer mechanism 102 and its corresponding carrier unit 101 together form an access unit 103. The distance between adjacent sheets in this access unit 103 is kept consistent, and this sheet distance is adapted to the distance between adjacent suction cup structures in the handling mechanism, which is convenient for the handling mechanism to transfer. The buffer mechanism 102 can complete the sheet splitting action when taking sheets and the sheet assembling action when placing sheets at the location of the first container. The handling mechanism does not need to undertake the functions of sheet splitting and assembling like the suction cup manipulator in the prior art. Therefore, the design can be significantly simplified, the equipment cost can be saved, the handling operation time is also shortened, which is beneficial to improving the overall beat.

[0054] S120: Transfer all the sheets in the access unit 103 to the second container.

[0055] Specifically, step S120 includes: Transfer all the sheets in the access unit 103 to the dry flower basket 21 through the handling mechanism.

[0056] The second working state S2 includes the following steps:

[0057] S210: Combine the empty carrier unit 101 and the empty buffer mechanism 102 to form an access unit 103.

[0058] Specifically, step S210 includes: Move the empty buffer mechanism 102 to one side of the corresponding empty carrier unit 101, and the two are arranged side by side. At this time, the empty carrier unit 101 and its corresponding empty buffer mechanism 102 together form an empty access unit 103.

[0059] S220: Transfer the sheets in the second container to the access unit 103.

[0060] Specifically, step S220 includes: transferring the sheets in the wet flower basket 22 to the carrying unit 101 and the corresponding buffer mechanism 102 through the handling mechanism. At this time, the number of sheets in the carrying unit 101 is the same as the number of sheets in the buffer mechanism 102, and the spacing between adjacent sheets in the access unit 103 remains consistent.

[0061] S230: Merge the sheets in the access unit 103 so that the sheets in the buffer mechanism 102 and the sheets in the carrying unit 101 are placed in a combined manner.

[0062] Specifically, step S230 includes: The buffer mechanism 102 includes a lifting member. Transfer the sheets in the buffer tooth grooves of the buffer mechanism 102 to the lifting member, and then the lifting member inserts the sheets into the tooth grooves of the carrying unit 101, so that each tooth groove in the carrying unit 101 carries two sheets, that is, the sheets placed by the lifting member correspond one by one to the sheets loaded in the tooth grooves, and they are placed in a combined manner.

[0063] The buffer mechanism 102 switches between the first working state S1 and the second working state S2 for operation. Specifically, when some of the buffer mechanisms 102 are in the first working state S1, the other buffer mechanisms 102 are in the second working state S2, and the first working state S1 and the second working state S2 alternate for operation. When the buffer mechanism in the first working state S1 cooperates with the handling mechanism, the buffer mechanism in the second working state S2 can have time to perform operation preparation. The two working states cooperate with each other, which can avoid the waiting of the handling mechanism and maximize the handling efficiency.

[0064] This application sets multiple buffer mechanisms 102 corresponding to the first container, so that the buffer mechanism 102 can form a temporary access unit 103 with the corresponding carrying unit 101, enabling the handling mechanism to transfer more sheets at one time. And because the sheets are split from the original combined state, it is more convenient for the handling mechanism to quickly transfer the sheets. At the same time, the multiple buffer mechanisms 102 of this application switch between two different working states for operation, that is, when some of the buffer mechanisms 102 are in the first working state S1, the other buffer mechanisms 102 are in the second working state S2, which can make full use of time and devices to transfer sheets in different states and improve the sheet guiding efficiency.

[0065] Optionally, the first container is configured with multiple buffer mechanisms 102, and the multiple buffer mechanisms 102 can simultaneously split or merge the sheets in their respective corresponding carrying units 101. This method can further improve the sheet guiding efficiency. In other embodiments, when the time required for the handling mechanism to transfer sheets is long, each first container can also be configured with only one buffer mechanism 102 to match the rhythm of the handling mechanism.

[0066] Further, when a part of the buffer mechanism 102 performs step S110, another part of the buffer mechanism 102 can simultaneously perform step S210 and perform step S220; when a part of the buffer mechanism 102 performs step S120, another part of the buffer mechanism 102 can perform step S230. Specifically, when a part of the buffer mechanism moves to one side of the fully loaded carrier unit 101, another part of the empty buffer mechanism moves to one side of the empty carrier unit 101; when a part of the sheets in the carrier unit 101 are transferred to the buffer mechanism to form a fully loaded access unit 103, the handling mechanism transfers the sheets in the wet flower basket 22 to the empty access unit 103; when the handling mechanism transfers the sheets in the access unit 103 to the dry flower basket 21, the sheets in another part of the buffer mechanism 102 are merged into the carrier unit 101. Different buffer mechanisms 102 alternately perform different steps of processing, so that the handling mechanism will not be in a vacant state. Only one set of handling mechanism is needed to complete the transfer of green and clinker materials, making the guiding of sheets more efficient.

[0067] Optionally, at least two first containers are provided. The working states of the multiple buffer mechanisms 102 configured for the same first container are kept consistent, and the working states of the buffer mechanisms 102 configured for different first containers are staggered correspondingly. By staggering the working states of the buffer mechanisms 102 configured for different first containers (i.e., wafer carriers), the mechanisms corresponding to each first container are in different operating states, so that the operations between multiple first containers will not conflict, nor will the handling mechanism be in a vacant state, ensuring the high efficiency of sheet guiding. For example, the handling mechanism first operates at the first container corresponding to the buffer mechanism in the first working state. At the same time, the buffer mechanism of another first container is in the second working state to perform the operation of combining and storing sheets, and the working states of the storage mechanisms on the two first containers are alternately switched.

[0068] Optionally, the second containers are provided in pairs and are respectively placed at the first sub-station and the second sub-station; the second container at the first sub-station correspondingly carries the sheets loaded in the carrier unit in the access unit, and the second container at the second sub-station correspondingly carries the sheets loaded in the buffer mechanism in the access unit.

[0069] Specifically, both the dry flower baskets and the wet flower baskets are provided in pairs. Among them, the dry flower basket 21 located on the first sub-station correspondingly receives the sheet materials from the carrying unit 101 in the access unit 103, and the dry flower basket 21 located on the second sub-station correspondingly receives the sheet materials from the buffer mechanism 102 in the access unit 103. The reason for such a setting is that when the two sheet materials assembled and loaded in the first container are subjected to the coating process, the coating is performed on the outer side, while the relatively adhered side is not coated. Therefore, the coating surfaces of the two sheet materials face in opposite directions. The buffer mechanism can transfer the sheet material with one coating surface facing to its own buffer tooth grooves, and then the handling mechanism can store the sheet materials with two different coating surface directions in different second containers respectively. Only by turning a part of them 180° when handling the second container later, the coating surfaces of all sheet materials can be made to face in the same direction.

[0070] The wet flower basket 22 located on the first sub-station correspondingly carries the sheet materials transferred to the carrying unit 101 in the access unit 103, and the wet flower basket 22 located on the second sub-station correspondingly carries the sheet materials transferred to the buffer mechanism 102 in the access unit 103.

[0071] Refer to Figure 3a 、 Figure 3b 、 Figure 3c 、 Figure 3d 、 Figure 3e and Figure 3f In this embodiment, the number of the wafer boats is two, namely the first wafer boat 11 and the second wafer boat 12. Each wafer boat is correspondingly provided with two buffer mechanisms 102, and there are two dry flower baskets 21 and two wet flower baskets 22, namely the first dry flower basket 211, the second dry flower basket 212, the first wet flower basket 221 and the second wet flower basket 222. The first dry flower basket 211 and the first wet flower basket 221 are located on the first sub-station, and the second dry flower basket 212 and the second wet flower basket 222 are located on the second sub-station. Each wafer boat includes eight carrying units 101 (shown by thick lines in the figure), each carrying unit 101 can carry at most 240 sheet materials, and one buffer mechanism 102 can carry at most 120 sheet materials. In the figure, the yellow color blocks represent the plastic materials, the red color blocks represent the plastic materials in the buffer mechanism 102, the green color blocks represent the raw materials, and the blue color blocks represent the raw materials in the buffer mechanism 102.

[0072] The first step: Refer to Figure 3a , Figure 3aIt is a schematic diagram of the first step of an implementation method of the guiding sheet in this application. In the first guiding sheet station 10 of this step, both the first carrier boat 11 and the second carrier boat 12 are fully loaded with clinker. Two buffer mechanisms 102 are respectively provided corresponding to the first carrier boat 11 and the second carrier boat 12. The two buffer mechanisms 102 respectively move to one side of the loading units 101 at the first and third positions. At this time, half of the sheet materials in the loading units 101 corresponding to the buffer mechanisms 102 are simultaneously transferred into the buffer mechanisms 102, and two access units 103 are formed in each carrier boat. At the same time, in the second guiding sheet station 20, the first wet flower basket 221 and the second wet flower basket 222 carry green materials.

[0073] Optionally, in this embodiment, one loading unit 101 is provided at an interval between the two access units 103, which is convenient for the subsequent handling mechanism to transfer and prevents interference between two adjacent access units 103 during the transfer process. In other embodiments, the two access units 103 may also be arranged adjacent to each other, or more loading units 101 may be spaced apart.

[0074] Optionally, in this embodiment, the two buffer mechanisms 102 of each carrier boat can split and move the sheet materials simultaneously to shorten the execution time of this step and improve the efficiency. In other embodiments, there may also be a certain time difference in the operations of the two buffer mechanisms 102.

[0075] In other embodiments, the number of buffer mechanisms 102 provided corresponding to each carrier boat may also be four, six, etc., and this application does not make specific limitations.

[0076] The second step, refer to Figure 3b , Figure 3bIt is a schematic diagram of the second step of an embodiment of the guiding sheet method of the present application. In this step, a handling mechanism (not shown in the figure) transfers all the sheets in the two access units 103 in the first carrier boat 11 to two dry flower baskets. At this time, both access units 103 are in an empty state. In this embodiment, the full-load sheet quantity of the handling mechanism is an integer multiple of the sheet quantity corresponding to one access unit 103 to ensure that the handling mechanism can transfer at full load and guarantee the efficiency. Optionally, when the full-load sheet quantity of the handling mechanism is 1 times the sheet quantity corresponding to one access unit 103, that is, the handling mechanism can suck 240 sheets at the same time, the two access units 103 can be transferred to the dry flower basket 21 successively. When the first access unit 103 finishes the transfer, the first dry flower basket 211 and the second dry flower basket 212 first complete half of the loading. When the second access unit 103 finishes the transfer, the first dry flower basket 211 and the second dry flower basket 212 are fully loaded. When the full-load sheet quantity of the handling mechanism is 2 times the sheet quantity corresponding to one access unit 103, that is, the handling mechanism can suck 480 sheets at the same time, then the two access units 103 can also be transferred to the dry flower basket 21 at the same time. In other embodiments, the full-load sheet quantity of the handling mechanism may not be a multiple relationship with the sheet quantity corresponding to one access unit 103.

[0077] The third step, refer to Figure 3c , Figure 3c It is a schematic diagram of the third step of an embodiment of the guiding sheet method of the present application. In this step, the handling mechanism transfers the raw materials in the two wet flower baskets 22 to the empty access units 103 in the first carrier boat 11 respectively. At this time, the quantity of raw materials in the loading unit 101 and the buffer mechanism 102 in each access unit 103 is the same. At the same time, in the second guiding sheet station 20, the dry flower basket 21 carrying the clinker is replaced by the empty first dry flower basket 211 and the second dry flower basket 212. Optionally, similar to the dry flower basket 21, the raw materials in the wet flower basket 22 can be transferred to the two access units 103 successively. When the first access unit 103 finishes the transfer, the first wet flower basket 221 and the second wet flower basket 222 first complete half of the transfer. When the second access unit 103 finishes the transfer, the first wet flower basket 221 and the second wet flower basket 222 are empty. Of course, the raw materials in the wet flower basket 22 can also be transferred to the two access units 103 at the same time.

[0078] The fourth step, refer to Figure 3d , Figure 3dIt is a schematic diagram of the fourth step of an implementation manner of the wafer guiding method of the present application. In this step, the sheets in the access unit 103 of the first wafer carrier boat 11 are combined, so that the sheets in the buffer mechanism 102 are transferred to the corresponding carrier unit 101 and placed together with the sheets in the carrier unit 101. At this time, the buffer mechanism 102 is in an empty state, and the carrier unit 101 is in a full state. At this time, the sheets carried by the two carrier units 101 of the first wafer carrier boat 11 are changed from cooked materials to raw materials. At the same time, in this step, the second wafer carrier boat 12 performs the same operation as the first wafer carrier boat 11 in the aforementioned second step. And at this time, in the second wafer guiding station 20, the originally empty wet flower basket 22 is replaced by the first wet flower basket 221 and the second wet flower basket 222 carrying raw materials. At this time, both the dry flower basket 21 and the wet flower basket 22 are in a full state.

[0079] Optionally, the two buffer mechanisms 102 can transfer and combine the sheets successively, or can transfer and combine them synchronously.

[0080] The fifth step, refer to Figure 3e , Figure 3e It is a schematic diagram of the fifth step of an implementation manner of the wafer guiding method of the present application. In this step, the two buffer mechanisms 102 are respectively moved to one side of the second and fourth carrier units 101 of the first wafer carrier boat 11. At this time, half of the sheets in the carrier units 101 corresponding to the buffer mechanisms 102 are simultaneously transferred to the buffer mechanisms 102, and each wafer carrier boat forms two access units 103. Except that the position of the carrier unit 101 is different from that in the first step, the remaining operations are the same as those in the first step; at the same time, the second wafer carrier boat 12 performs the same operation as the first wafer carrier boat 11 in the third step and replaces the empty dry flower basket 21, which is the same as the third step.

[0081] The sixth step, refer to Figure 3f , Figure 3f It is a schematic diagram of the sixth step of an implementation manner of the wafer guiding method of the present application. In this step, the operation of the handling mechanism is the same as that in the second step, except that the two access units 103 are each shifted backward by one position, that is, they are the access units 103 corresponding to the second and fourth carrier units 101 respectively; at the same time, the second wafer carrier boat 12 performs the same operation as the first wafer carrier boat 11 in the fourth step. And at this time, in the second wafer guiding station 20, the originally empty wet flower basket 22 is replaced by the first wet flower basket 221 and the second wet flower basket 222 carrying raw materials. At this time, both the dry flower basket 21 and the wet flower basket 22 are in a full state.

[0082] Then, the operation of the next set of carrier units 101 of the first wafer carrier boat 11 is the same as that in the third step, and the operation of the next set of carrier units 101 of the second wafer carrier boat 12 is the same as that in the fifth step, that is, the same operation as the first wafer carrier boat 11 in the third step, and so on, realizing the cycle of steps until all the sheets are replaced.

[0083] The number of the first containers shown in this embodiment is two. In other embodiments, the guiding sheet method used in this embodiment can also be applied to a greater number of the first containers.

[0084] This embodiment shows that the working states of the buffer mechanisms 102 configured for different first containers (i.e., wafer boats) are staggered correspondingly, while the working states of the buffer mechanisms 102 configured for the same first container are consistent.

[0085] In some other embodiments, the working states of adjacent buffer mechanisms 102 configured for the same first container are staggered correspondingly. Taking the example that one first container is correspondingly configured with two buffer mechanisms 102, when the first buffer mechanism 102 and the corresponding carrier unit 101 are in the first working state S1, the second buffer mechanism 102 and the corresponding carrier unit 101 are in the second working state S2, that is, different buffer mechanisms 102 of the same container perform alternating operations. Optionally, in this embodiment, the number of the first containers can be one or multiple.

[0086] The above are only the implementation manners of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present application.
