DETAILED DESCRIPTION

[0024] In order to make the purpose, 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 combination with the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0025] See also Figure 1a , Figure 1a It is a schematic diagram of the structure of the first embodiment of the sheet guide system of the present application. The sheet guide system 100 includes a first sheet guide station 10, a second sheet guide station 20, a conveying mechanism (not shown) and a cache mechanism 102. The first sheet guide station 10 is used to place the first container. The second sheet guide station 20 is used to place the second container. The conveying mechanism is used to transfer sheets between the first container and the second container. The cache mechanism 102 is used to split or merge the sheets in the first container. The first container has a plurality of carrying units 101, and the cache mechanism 102 can form an access unit 103 together with the carrying unit 101, which is used to load the sheets obtained by splitting from the combined state in the carrying unit 101.

[0026] also, Figure 1a The first container, the second container and the cache mechanism shown in the figure are all composed of multiple minimum rectangles, the minimum rectangle represents a specific amount of sheet loading, when the minimum rectangle is white, it means empty, when the minimum rectangle is other filling colors, it means loaded with sheets; the number of first containers in the figure is 2, namely the first wafer boat 11 and the second wafer boat 12, and the first wafer boat 11 is taken as an example for specific description: the first wafer boat 11 is composed of 32 minimum rectangles, and 2 cache mechanisms are configured on the right side; wherein, every 4 minimum rectangles distributed in a field shape represent 1 carrying unit, and there are 8 carrying units from top to bottom in the first wafer boat 11, and the 2 cache mechanisms in the figure correspond to the first carrying unit and the third carrying unit respectively.

[0027] See also Figure 1b , Figure 1bIt is a structural schematic diagram of the second embodiment of the guide system provided in the present application, which is illustrated by the cooperation between a specific load-bearing unit and a cache mechanism. The four minimum rectangles on the left side of the figure represent one load-bearing unit. Taking a single minimum rectangle representing a load of 60 sheets as an example, this load-bearing unit can load 240 sheets, and the cache mechanism on the right side includes 2 minimum rectangles, that is, the load capacity is 120.

[0028] Wherein, each tooth groove in the carrying unit for loading sheets can accommodate two sheets, and each tooth groove in the buffer mechanism and the second container for loading sheets can accommodate one sheet.

[0029] See also Figure 1c , Figure 1c 1 is a schematic diagram of the structure of the third embodiment of the sheet guide system provided by the present application. The upper half of the figure shows that the load-bearing unit is fully loaded with 240 sheets, which are stored in pairs in 120 tooth grooves; the lower half of the figure shows that after the sheets in the combined state in the load-bearing unit are split, 120 sheets are still stored in the 120 tooth grooves individually, and the other 120 sheets are stored in the tooth grooves of the buffer mechanism individually; See also Figure 1d , Figure 1d It is a structural schematic diagram of the fourth embodiment of the sheet guide system provided in the present application. The upper part of the figure is a storage and access unit composed of a bearing unit and a cache mechanism, which stores 240 sheets transferred from the second container. The lower part of the figure is a merging of the sheets in the storage and access unit, so that the 120 sheets in the cache mechanism and the 120 sheets in the bearing unit are stored in pairs in 120 tooth grooves.

[0030] Specifically, the first container is a wafer boat for carrying sheets, each wafer boat includes a plurality of carrying units 101, each carrying unit 101 specifically includes a plurality of parallel distributed tooth grooves (not shown), each tooth groove can carry a group of two sheets in a sheet-joined state. In this embodiment, each wafer boat includes K carrying units 101, each carrying unit 101 includes N tooth grooves, each tooth groove can carry 2 sheets, that is, each carrying unit 101 can carry 2N sheets. A sheet guide system 100 may include one or more first containers, in which Figure 1a In the illustrated embodiment, there are two first containers, namely, wafer boats, namely, a first wafer boat 11 and a second wafer boat 12 . The two wafer boats are arranged side by side and have the same number of carrying units 101 .

[0031] The second container is a flower basket (not marked), which is used to carry sheets. According to the state of the sheets carried, the flower basket is divided into a dry flower basket 21 and a wet flower basket 22. The dry flower basket 21 is used to carry the processed sheets (cooked materials) transferred from the sheet-carrying boat, and the wet flower basket 22 is used to carry the sheets (raw materials) to be processed and transferred to the sheet-carrying boat. The dry flower basket 21 and the wet flower basket 22 have the same structure and can carry the same number of sheets. In this embodiment, one flower basket can carry 2N sheets.

[0032] The cache mechanism 102 may specifically include a plurality of cache tooth grooves (not shown), each of which may carry a sheet. The cache mechanism 102 may be correspondingly arranged on one side of the carrier unit 101 of the wafer boat, and the cache mechanism 102 and the corresponding carrier unit 101 together constitute an access unit 103.

[0033] In one embodiment, the number of the buffer mechanism 102 is one, and the speed at which the buffer mechanism splits and merges the sheets in the carrier unit 101 matches the speed at which the transport mechanism transfers the sheets between the wafer boat and the basket.

[0034] In one embodiment, there are multiple cache mechanisms 102. When there is one wafer boat, multiple cache mechanisms 102 are correspondingly arranged for one wafer boat; when there are multiple wafer boats, one or more cache mechanisms 102 are correspondingly arranged for each wafer boat. In this embodiment, two wafer boats are respectively correspondingly provided with two cache mechanisms 102, and the two cache mechanisms 102 respectively correspond to two spaced-apart carrying units 101 in each wafer boat. At the same time, the cache mechanisms 102 can be moved to switch to correspond to different carrying units 101. Keeping the carrying units 101 corresponding to different cache mechanisms 102 spaced apart can provide sufficient space for the operation of the cache mechanisms 102, thereby avoiding structural or action interference between adjacent cache mechanisms 102.

[0035] In another embodiment, the carrying units 101 corresponding to the plurality of cache mechanisms 102 may also be arranged adjacent to each other.

[0036] In another embodiment, the first container is provided with a first operating area and a second operating area, and the first operating area and the second operating area respectively include a plurality of continuously distributed carrying units; the working states of the cache mechanism configured in the first operating area and the cache mechanism configured in the second operating area are staggered. Figure 1a, every 4 smallest rectangles distributed in a field shape represent 1 carrying unit, then there are 8 carrying units from top to bottom in the first wafer boat 11, among which the upper 4 carrying units can be divided into the first operating area, and the lower 4 carrying units can be divided into the second operating area; each operating area can be configured with 1-2 cache mechanisms, so that the transport mechanism can switch the operating area between the first operating area and the second operating area according to the different transport directions, the working state of the cache mechanism inside each operating area is consistent, and the slice control of the cache mechanism can be realized. Multiple cache mechanisms of the same slice can improve fault tolerance and effectively deal with local failures. At the same time, it can simplify the overall automation scheduling complexity of the wafer guide system, and facilitate the flexible adjustment of the operating area zoning according to changes in production capacity rhythm.

[0037] The transport mechanism is used to transfer sheets between the first container and the second container, and specifically, the transport mechanism is used to transfer sheets between the access unit 103 and the second container. The transport mechanism can transfer the processed sheets from the film boat and the buffer mechanism 102 to the dry flower basket 21, and can also transfer the sheets to be processed from the wet flower basket 22 to the film boat and the buffer mechanism 102. Optionally, the transport mechanism is arranged above the first container and the second container to make full use of the space to avoid affecting the film boat and the flower basket during the transport process, and can also make the arrangement of the first container and the second container more compact, saving the area occupied by the film guide system and saving production space.

[0038] In one embodiment, the transport mechanism may be a suction cup robot.

[0039] In one embodiment, the transport mechanism may be an overhead crane, which can suck up multiple sheets at a time through a suction cup. Compared with a manipulator, an overhead crane has lower procurement and maintenance costs, is more suitable for transferring a large number of sheets at a time, and can well meet the requirements for increasing production capacity.

[0040] See also Figure 2 , Figure 2 1 is a flow chart of an embodiment of a film guiding method of the present application. The film guiding method is applied to a film guiding system 100, and the method includes two working states, a first working state S1 and a second working state S2, wherein the first working state S1 includes the following steps: S110 : splitting the sheets in the combined state in the carrying unit 101 , and storing the surplus sheets in the buffer mechanism 102 , so that the carrying unit 101 and the buffer mechanism 102 together constitute an access unit 103 .

[0041] Specifically, step S110 includes: the cache mechanism 102 includes a lifting member, through which one of the two sheets in the sheet-joined state in each tooth groove of one or more bearing units 101 is ejected, and the sheets in each tooth groove are split. At this time, the unloaded cache mechanism 102 can be moved to the side of the corresponding bearing unit 101, and the two are arranged side by side. Then all the ejected sheets are transferred from the lifting member to the cache tooth groove of the corresponding cache mechanism 102, that is, half of the sheets in the bearing unit 101 are transferred to the cache mechanism 102. At this time, the number of sheets carried in the cache mechanism 102 is the same as the number of sheets carried in the corresponding bearing unit 101. The cache mechanism 102 and the corresponding bearing unit 101 together constitute an access unit 103. The spacing between adjacent sheets in the access unit 103 is consistent, and the sheet spacing is adapted to the spacing between adjacent suction cup structures in the conveying mechanism, so as to facilitate the transfer of the conveying mechanism. The cache mechanism 102 can complete the slice separation action when taking the slices and the slice closing action when placing the slices at the location of the first container, and the transport mechanism does not need to perform the slice separation and closing functions like the suction cup robot in the prior art. Therefore, it can significantly simplify the design, save equipment costs, shorten the transport operation time, and help improve the overall beat.

[0042] S120: Transfer all sheets in the access unit 103 to the second container.

[0043] Specifically, step S120 includes: transferring all the sheets in the storage and access unit 103 to the dried flower basket 21 through the transport mechanism.

[0044] The second working state S2 includes the following steps: S210: The unloaded carrying unit 101 and the unloaded cache mechanism 102 form an access unit 103.

[0045] Specifically, step S210 includes: moving the unloaded cache mechanism 102 to a side of the corresponding unloaded carrying unit 101 , and arranging the two side by side. At this time, the unloaded carrying unit 101 and the corresponding unloaded cache mechanism 102 constitute an unloaded access unit 103 .

[0046] S220 : Transferring the sheets in the second container to the storage and access unit 103 .

[0047] Specifically, step S220 includes: transferring the sheets in the wet flower basket 22 to the carrying unit 101 and the corresponding cache mechanism 102 through the transport mechanism, at which time the number of sheets in the carrying unit 101 is the same as the number of sheets in the cache mechanism 102, and the spacing between adjacent sheets in the access unit 103 remains consistent.

[0048] S230 : The sheets in the access unit 103 are combined so that the sheets in the buffer mechanism 102 and the sheets in the carrying unit 101 are placed together.

[0049] Specifically, step S230 includes: the cache mechanism 102 includes a lifting member, the sheet in the cache groove of the cache mechanism 102 is transferred to the lifting member, and then the lifting member inserts the sheet into the groove of the carrying unit 101, so that each groove in the carrying unit 101 carries two sheets, that is, the sheet inserted by the lifting member corresponds one by one to the sheet loaded in the groove, and the sheets are placed together.

[0050] The cache mechanism 102 switches between the first working state S1 and the second working state S2. Specifically, when part of the cache mechanism 102 is in the first working state S1, the other part of the cache mechanism 102 is in the second working state S2, and the first working state S1 and the second working state S2 work alternately. When the cache mechanism in the first working state S1 cooperates with the transport mechanism, the cache mechanism in the second working state S2 can have time to prepare for operation. The two working states cooperate with each other, which can avoid the transport mechanism from waiting and maximize the transport efficiency.

[0051] The present application sets a plurality of cache mechanisms 102 corresponding to the first container, so that the cache mechanism 102 can form a temporary access unit 103 with the corresponding carrying unit 101, so that the transport mechanism can transfer more sheets at one time, and because the sheets are separated from the original combined state, it is more convenient for the transport mechanism to quickly transfer the sheets. At the same time, the plurality of cache mechanisms 102 of the present application switch operations between two different working states, that is, when some cache mechanisms 102 are in the first working state S1, the other cache 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 efficiency of sheet guiding.

[0052] Optionally, the first container is equipped with a plurality of cache mechanisms 102, and the plurality of cache mechanisms 102 can simultaneously split or merge the sheets in the corresponding carrying units 101. This method can further improve the efficiency of sheet guiding. In other embodiments, when the time required for the transport mechanism to transfer the sheets is long, each first container can also be equipped with only one cache mechanism 102 to match the rhythm of the transport mechanism.

[0053] Further, when part of the buffer mechanism 102 performs step S110, another part of the buffer mechanism 102 can perform step S210 and step S220 at the same time; when part of the buffer mechanism 102 performs step S120, another part of the buffer mechanism 102 can perform step S230. Specifically, when part of the buffer mechanism moves to the side of the fully loaded carrying unit 101, another part of the unloaded buffer mechanism moves to the side of the unloaded carrying unit 101; when part of the sheets in the carrying unit 101 are transferred to the buffer mechanism to form a fully loaded access unit 103, the transport mechanism transfers the sheets in the wet flower basket 22 to the unloaded access unit 103; when the transport 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 carrying unit 101. Different buffer mechanisms 102 process different steps alternately, so that the transport mechanism will not be in an idle state. Only one set of transport mechanism is required to complete the transfer of raw materials and cooked materials, making the guide plate more efficient.

[0054] Optionally, at least two first containers are provided, and the working states of the multiple cache mechanisms 102 configured in the same first container are kept consistent, and the working states of the cache mechanisms 102 configured in different first containers are staggered. By staggering the working states of the cache mechanisms 102 configured in different first containers (i.e., film boats), the mechanisms corresponding to each first container are in different working states, so that the operations between the multiple first containers will not conflict, and the transport mechanism will not be in an idle state, thereby ensuring the high efficiency of the sheet guide. For example, the transport mechanism first operates at the first container corresponding to the cache mechanism in the first working state, while at the same time, the cache mechanism of another first container is in the second working state to perform the operation of combining and storing the sheets, and the working states of the storage mechanisms on the two first containers are switched alternately.

[0055] Optionally, the second containers are arranged in pairs and placed at the first sub-station and the second sub-station respectively; the second container on the first sub-station corresponds to the sheets loaded by the carrying unit in the carrying access unit, and the second container on the second sub-station corresponds to the sheets loaded by the cache mechanism in the carrying access unit.

[0056] Specifically, the dry flower basket and the wet flower basket are arranged in pairs, wherein the dry flower basket 21 located at the first sub-station corresponds to the sheet from the carrying unit 101 in the access unit 103, and the dry flower basket 21 located at the second sub-station corresponds to the sheet from the cache mechanism 102 in the access unit 103. The reason for this arrangement is that when the two sheets of sheet material loaded in the first container are subjected to the coating process, the side facing outward is coated, while the side facing each other is not coated, so the coated surfaces of the two sheets face opposite directions, and the cache mechanism can transfer one of the sheets with the coated surface facing to its own cache tooth groove, and the transport mechanism can store the sheets with the two coated surface directions in different second containers respectively, and only a part of the sheets needs to be turned 180° when the second container is subsequently transported, so that the coated surface directions of all sheets can be kept consistent.

[0057] The wet flower basket 22 located at the first sub-station corresponds to the sheet material in the carrying unit 101 transferred to the access unit 103 , and the wet flower basket 22 located at the second sub-station corresponds to the sheet material in the buffer mechanism 102 transferred to the access unit 103 .

[0058] See also Figure 3a , Figure 3b , Figure 3c , Figure 3d , Figure 3e and Figure 3f In this embodiment, there are two film boats, namely the first film boat 11 and the second film boat 12. Each film boat is provided with two corresponding buffer mechanisms 102. The dry flower basket 21 and the wet flower basket 22 are provided with two each, 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 at the first sub-station, and the second dry flower basket 212 and the second wet flower basket 222 are located at the second sub-station. Each film boat includes eight carrying units 101 (shown by the thick lines in the figure). Each carrying unit 101 can carry up to 240 sheets, and one buffer mechanism 102 can carry up to 120 sheets. In the figure, the yellow block represents the cooked material, the red block represents the cooked material in the buffer mechanism 102, the green block represents the raw material, and the blue block represents the raw material in the buffer mechanism 102.

[0059] Step 1: Read Figure 3a , Figure 3aIt is a schematic diagram of the first step of the first implementation method of the present application. In the first sheet guiding station 10 of this step, the first sheet boat 11 and the second sheet boat 12 are both fully loaded with clinker, and the first sheet boat 11 and the second sheet boat 12 are respectively provided with two buffer mechanisms 102, and the two buffer mechanisms 102 are respectively moved to the first and third load units 101. At this time, half of the sheets in the load units 101 corresponding to the buffer mechanisms 102 are simultaneously transferred to the buffer mechanisms 102, and each sheet boat forms two access units 103. At the same time, in the second sheet guiding station 20, the first wet basket 221 and the second wet basket 222 are loaded with raw materials.

[0060] Optionally, in this embodiment, a carrier unit 101 is provided between two access units 103 to facilitate subsequent transfer by the transport mechanism and prevent interference between two adjacent access units 103 during the transfer process. In other embodiments, two access units 103 may also be provided adjacent to each other or with more carrier units 101 provided between them.

[0061] Optionally, in this embodiment, the two buffer mechanisms 102 of each wafer boat can simultaneously split and move the sheets to shorten the execution time of this step and improve efficiency. In other embodiments, the operations of the two buffer mechanisms 102 can also have a certain time difference.

[0062] In other embodiments, the number of the cache mechanisms 102 corresponding to each wafer boat may also be four, six, etc., and this application does not impose any specific limitation.

[0063] Step 2: See Figure 3b , Figure 3bIt is a schematic diagram of the second step of the first implementation method of the film guide method of the present application. In this step, the transport mechanism (not shown) transfers all the sheets in the two access units 103 in the first film boat 11 to the two dried flower baskets, and at this time, the two access units 103 are both in an empty state. In this embodiment, the number of fully loaded sheets of the transport mechanism is an integer multiple of the number of sheets corresponding to one access unit 103, so as to ensure that the transport mechanism can be fully loaded and transferred to ensure efficiency. Optionally, when the number of fully loaded sheets of the transport mechanism is 1 times the number of sheets corresponding to one access unit 103, that is, the transport mechanism can absorb 240 sheets at the same time, the two access units 103 can be transferred to the dried flower basket 21 successively, and when the first access unit 103 completes the transfer, the first dried flower basket 211 and the second dried flower basket 212 first complete half of the loading, and when the second access unit 103 completes the transfer, the first dried flower basket 211 and the second dried flower basket 212 are fully loaded. When the number of sheets fully loaded by the transport mechanism is twice the number of sheets corresponding to one access unit 103, that is, the transport mechanism can absorb 480 sheets at the same time, then two access units 103 can also be transferred to the dried flower basket 21 at the same time. In other embodiments, the number of sheets fully loaded by the transport mechanism may not be a multiple of the number of sheets corresponding to one access unit 103.

[0064] Step 3: See Figure 3c , Figure 3c : is a schematic diagram of the third step of the first implementation method of the film guide method of the present application. In this step, the transport mechanism transfers the raw materials in the two wet flower baskets 22 to the empty access units 103 in the first film carrier boat 11, respectively. At this time, the amount of raw materials in the carrying unit 101 and the cache mechanism 102 in each access unit 103 is the same. At the same time, in the second film guide station 20, the dry flower basket 21 loaded with cooked materials 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 in succession. When the first access unit 103 completes 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 completes 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.

[0065] Step 4: See Figure 3d , Figure 3d: is a schematic diagram of the fourth step of the first implementation method of the film guiding method of the present application. In this step, the sheets in the access unit 103 in the first film carrier boat 11 are merged, so that the sheets in the buffer mechanism 102 are transferred to the corresponding bearing unit 101, and placed together with the sheets in the bearing unit 101. At this time, the buffer mechanism 102 is in an empty state, and the bearing unit 101 is in a fully loaded state. At this time, the sheets carried by the two bearing units 101 of the first film carrier boat 11 are changed from cooked materials to raw materials. At the same time, in this step, the second film carrier boat 12 performs the same steps as the first film carrier boat 11 in the second step, and at this time, in the second film 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 loaded with raw materials. At this time, the dry flower basket 21 and the wet flower basket 22 are both fully loaded.

[0066] Optionally, the two buffer mechanisms 102 may transfer and combine the sheets successively, or may transfer and combine simultaneously.

[0067] Step 5: See Figure 3e , Figure 3e It is a schematic diagram of the fifth step of the first implementation method of the film guide method of the present application. In this step, the two buffer mechanisms 102 are respectively moved to the second and fourth side of the carrying unit 101 of the first film carrier boat 11. At this time, half of the sheets in the carrying unit 101 corresponding to the buffer mechanism 102 are simultaneously transferred to the buffer mechanism 102. Each film carrier boat forms two access units 103. Except that the position of the carrying unit 101 is different from the first step, the rest of the operations are the same as the first step; at the same time, the second film carrier boat 12 performs the same operation as the first film carrier boat 11 in the third step, and replaces the empty dried flower basket 21, which is the same as the third step.

[0068] Step 6. See Figure 3f , Figure 3f : is a schematic diagram of the sixth step of the first embodiment of the film guiding method of the present application. In this step, the operation of the transport mechanism is the same as that of the second step, the only difference is that the two access units 103 are both postponed one position, that is, the access units 103 corresponding to the second and fourth carrying units 101 respectively; at the same time, the second film carrying boat 12 performs the same operation as the first film carrying boat 11 in the fourth step, and at this time, in the second film 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 loaded with raw materials. At this time, the dry flower basket 21 and the wet flower basket 22 are both fully loaded.

[0069] Then, the operation of the next group of carrying units 101 of the first wafer boat 11 is the same as that in the third step, and the operation of the next group of carrying units 101 of the second wafer boat 12 is the same as that in the fifth step, that is, the same operation as that of the first wafer boat 11 in the third step is performed, and so on, a cycle of steps is realized until the replacement of all sheets is completed.

[0070] The number of first containers shown in this embodiment is two. In other embodiments, the guide plate method used in this embodiment can also be applied to a larger number of first containers.

[0071] This embodiment shows that the working states of the buffer mechanisms 102 configured in different first containers (ie, wafer boats) are staggered, while the working states of the buffer mechanisms 102 configured in the same first container remain consistent.

[0072] In other embodiments, the working states of adjacent cache mechanisms 102 configured in the same first container are staggered. For example, when two cache mechanisms 102 are configured in correspondence with one first container, when the first cache mechanism 102 and the corresponding carrying unit 101 are in the first working state S1, the second cache mechanism 102 and the corresponding carrying unit 101 are in the second working state S2, that is, different cache mechanisms 102 of the same container operate alternately. Optionally, in this embodiment, the number of first containers can be one or more.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
