[0059] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0060] In the production process of battery cells, the material box needs to be circulated in different processes. The material box is used to store silicon wafers or battery cells. However, the existing method of collecting wafers is usually to stack them one by one in the material box to form a stack. This method easily causes the air between two adjacent layers of the stack to be unable to be completely discharged, causing the material box containing the stack to be easily scattered during transportation.

[0061] Therefore, this application proposes a material box circulation device, please refer to Figure 1 As shown, the material box circulation device proposed in the embodiment of the present application includes a first transfer mechanism 10, an exhaust mechanism 20 and a first conveying mechanism 30, wherein: the first transfer mechanism 10 is configured to receive a material box 40 containing stacked sheets, and convey the received material box 40 containing stacked sheets to the first conveying mechanism 30, and the stacked sheets are a plurality of sheets stacked in the material box 40; an exhaust station is provided on the conveying path of the first transfer mechanism 10 or the first conveying mechanism 30, and the exhaust mechanism 20 is provided at the exhaust station, and the exhaust mechanism 20 is configured to press the stacked sheets in the material box 40 at the exhaust station to discharge the air between two adjacent layers of sheets of the stacked sheets in the material box 40; the first conveying mechanism 30 is configured to receive the material box 40 containing stacked sheets conveyed by the first transfer mechanism 10, and cache the received material box 40 containing stacked sheets or convey the received material box 40 containing stacked sheets to the next process.

[0062] It can be seen that the material box circulation device proposed in the present application realizes the automatic circulation of the material box 40 containing the stacked sheets through the cooperation of the first transfer mechanism 10 and the first conveying mechanism 30; at the same time, an exhaust station is arranged on the conveying path of the first transfer mechanism 10 or the first conveying mechanism 30, and an exhaust mechanism 20 is arranged at the exhaust station. The stacked sheets in the material box 40 are pressed by the exhaust mechanism 20, and then the air between the two adjacent layers of the stacked sheets in the material box 40 is discharged, thereby avoiding the scattering of the material box 40 containing the stacked sheets during the transportation process due to the incomplete discharge of the air between the adjacent sheets, thereby improving the circulation efficiency of the material box 40 containing the stacked sheets, and also protecting the stacked sheets to avoid damage after the sheets are scattered.

[0063] As an implementation, see Figure 2 and Figure 3 As shown, the exhaust mechanism 20 includes a first driving member 21 and a pressing member 22. The driving end of the first driving member 21 is connected to the pressing member 22. The first driving member 21 is configured to drive the pressing member 22 to rise and fall so as to press or move away from the laminated sheets in the material box 40 at the exhaust station; the first driving member 21 drives the pressing member 22 to descend, so that the pressing member 22 presses the laminated sheets in the material box 40 to discharge the air between adjacent sheets of the laminated sheets; the laminated sheets in the material box 40 are inclined at a predetermined angle, and the pressing surface of the pressing member 22 is inclined at a predetermined angle so as to achieve a pressed surface that fits the uppermost sheet of the laminated sheets in the material box 40 when pressed.

[0064] It can be seen that, through the cooperation of the first driving member 21 and the pressing member 22, the laminations in the material box 40 are pressed to automatically discharge the air between adjacent sheets of the laminations. The laminations in the material box 40 are usually arranged at an inclination at a predetermined angle, so the pressing surface of the pressing member 22 is also arranged at an inclination at a predetermined angle, that is, the inclination angle of the pressing surface is consistent with the inclination angle of the lamination, so that the pressing surface of the pressing member 22 fits the pressed surface of the uppermost sheet of the lamination in the material box 40, ensuring that the pressing member 22 is in surface contact with the uppermost sheet of the lamination in the material box 40, which can avoid crushing the sheets and have a better exhaust effect.

[0065] As an embodiment, the first driving member 21 includes a first cylinder, the clamping member 22 is a pressure plate, a mounting frame 23 is arranged above the exhaust station, the fixed end of the first cylinder is mounted on the mounting frame 23, the driving end of the first cylinder is arranged downward, and the pressure plate is installed on the driving end of the first cylinder at an inclined angle according to a predetermined angle.

[0066] Specifically, a flexible pad is attached to the pressing surface of the pressing plate to prevent the pressing member 22 from making hard contact with the uppermost sheet in the stack.

[0067] It can be seen that by setting the pressing member 22 as a pressing plate and installing the pressing plate at a predetermined angle on the driving end of the first cylinder, an exhaust mechanism 20 with a simple structure, low cost and good exhaust effect is provided.

[0068] As an embodiment, the material box circulation device also includes a detection component 50 and a marking component 51, wherein: the detection component 50 is configured to detect whether the stacked sheets in the material box 40 are neatly stacked; the marking component 51 is configured to mark the material box 40 in which the stacked sheets detected by the detection component 50 are not neatly stacked.

[0069] It can be seen that by setting up the detection component 50, automatic detection of whether the stacked sheets in the material box 40 are neatly stacked is achieved; by setting up the marking component 51, automatic marking of the unevenly stacked material box 40 is achieved, so as to facilitate the subsequent processing of the unevenly stacked material box 40.

[0070] As an embodiment, the detection component 50 includes at least one first sensor 500 and at least one second sensor 501, at least one first sensor 500 is configured to detect whether the first side 52 of the stacked sheets in the material box 40 is neat, and at least one second sensor 501 is configured to detect whether the second side 53 of the stacked sheets in the material box 40 is neat, and the first side 52 is perpendicular to the second side 53; the marking component 51 includes a code reader, and the code reader is configured to read the identification code on the material box 40 to mark the material box 40 where the stacked sheets are not neatly stacked.

[0071] Specifically, the first sensor 500 and the second sensor 501 are both laser sensors. The first sensor 500 may be one or more, and the second sensor 501 may also be one or more. Figure 2 There are two first sensors 500 and second sensors 501 shown in the figure. The two first sensors 500 are hung on the mounting frame 23. The two first sensors 500 are arranged above the first side edge 52 of the laminate in the material box 40, and the two first sensors 500 are arranged at intervals along the length direction of the first side edge 52 of the aligned laminate. The two second sensors 501 are hung on the mounting frame 23. The two second sensors 501 are arranged above the second side edge 53 of the laminate in the material box 40, and the two second sensors 501 are arranged at intervals along the length direction of the second side edge 53 of the aligned laminate. When the laminate is aligned, there is no obstruction below the two first sensors 500 and the two second sensors 501, and the two first sensors 500 and the two second sensors 501 cannot receive any signal. When the laminate is not aligned, the unaligned sheets in the laminate will extend out to block at least one of the sensors, and the blocked sensor will receive a signal, indicating that the laminate in this material box 40 is not aligned.

[0072] It can be seen that the first sensor 500 and the second sensor 501 can detect whether the first side edge 52 and the second side edge 53 of the stacked sheets in the material box 40 are neat, thereby improving the accuracy of the detection result; the code reader can automatically read the identification code on the material box 40, thereby facilitating the marking of the material box 40 with unevenly stacked sheets. The identification code is a chip.

[0073] See also Figures 1 to 3 As shown, as an embodiment, the first transfer mechanism 10 includes a first conveying line 11 and a first reversing mechanism 12, wherein: the first conveying line 11 is configured to receive a material box 40 containing stacked sheets, and to transfer the received material box 40 containing stacked sheets along a first direction ( Figure 1 The exhaust mechanism 20 is disposed above the first reversing mechanism 12, and the first reversing mechanism 12 is configured to receive the material box 40 containing the stacked sheets conveyed by the first conveyor line 11, and switch the direction of the received material box 40 containing the stacked sheets along the second direction ( Figure 1 The surface of the substrate is transported to the first transport mechanism 30 (in the Y direction).

[0074] Specifically, the first reversing mechanism 12 includes a first conveyor belt 120 and a second conveyor belt 121 which are vertically crossed. The first conveyor belt 120 is driven by the first cylinder to be able to be raised and lowered. The first conveyor belt 120 can be raised and lowered to a high position and a low position relative to the second conveyor belt 121. When the first conveyor belt 120 is in a high position, the conveying surface of the first conveyor belt 120 is at the same height as the conveying surface of the first conveyor line 11 and is higher than the conveying surface of the second conveyor belt 121, so as to receive the material box 40 with stacked sheets conveyed by the first conveyor line 11. When the first conveyor belt 120 is lowered to a low position, the conveying surface of the first conveyor belt 120 is lower than the conveying surface of the second conveyor belt 121, so as to lower the material box 40 on the first conveyor belt 120 to the second conveyor belt 121, and the material box 40 is transported by the second conveyor belt 121 to realize vertical reversing transportation of the material box 40.

[0075] It can be seen that, through the cooperation of the first conveyor line 11 and the first reversing mechanism 12, the reversing transfer of the material box 40 containing the stacked sheets is realized, providing a first transfer mechanism 10 with a compact structure and a reasonable layout.

[0076] See also Figure 1 As shown, as an embodiment, the first conveying mechanism 30 includes at least two first conveying units 300 arranged side by side along the first direction, the first conveying unit 300 is configured to convey the material box 40 containing the stacked sheets along the second direction, the first transfer mechanism 10 also includes a first docking line 13 and a first transfer mechanism 14, the first docking line 13 is configured to receive the material box 40 containing the stacked sheets conveyed by the first reversing mechanism 12, and convey the received material box 40 containing the stacked sheets to the first conveying unit 300, the driving end of the first transfer mechanism 14 is connected to the first docking line 13, and the first transfer mechanism 14 is configured to drive the first docking line 13 to move laterally along the first direction to dock with different first conveying units 300.

[0077] Specifically, the marking component 51 is disposed on the first pair of wires 13 .

[0078] Specifically, the first transfer mechanism 14 includes a base 140, a transverse seat 141 and a second driving member 142. The transverse seat 141 can be installed on the base 140 for reciprocating movement along the first direction. The first docking line 13 is installed on the transverse seat 141. The fixed end of the second driving member 142 is installed on the base 140. The driving end of the second driving member 142 is connected to the transverse seat 141. The transverse seat 141 is driven by the second driving member 142 to move transversely along the first direction, so as to drive the first docking line 13 to move transversely along the first direction.

[0079] Specifically, the second driving member 142 includes a motor, a first pulley, a second pulley and a first transmission belt. The first pulley and the second pulley are spaced apart along the first direction. The fixed end of the motor is mounted on the base 140. The driving end of the motor is connected to the first pulley. The second pulley is rotatably mounted on the base 140. The first transmission belt is sleeved on the first pulley and the second pulley. The transverse shift seat 141 is fixedly connected to the first transmission belt. The motor drives the first transmission belt to rotate via the first pulley and the second pulley to drive the transverse shift seat 141 to move transversely along the first direction.

[0080] It can be seen that by setting up at least two first conveying units 300, the processing capacity of the first conveying mechanism 30 for caching or conveying the material box 40 containing the stacked sheets is improved; through the cooperation of the first docking line 13 and the first transfer mechanism 14, the first reversing mechanism 12 is docked with different first conveying units 300, which can meet the requirements of efficient and fast-paced circulation of the material box 40 containing the stacked sheets.

[0081] As an embodiment, the first conveying mechanism 30 is provided with at least two layers, each layer includes at least two first conveying units 300 arranged in parallel, and the first transfer mechanism 14 is also configured to drive the first docking line 13 to rise and fall to dock the first conveying units 300 at different heights.

[0082] Specifically, the first transfer mechanism 14 further includes a third driving member 143 , a driving end of the third driving member 143 is connected to the base 140 , and the third driving member 143 is configured to drive the base 140 to rise and fall, so as to drive the first docking line 13 to rise and fall to dock with the first conveying unit 300 at different heights.

[0083] It should be noted that the driving mode of the third driving member 143 is the same as that of the second driving member 142, both of which adopt a belt transmission method. The main difference is that the belt in the third driving member 143 is arranged vertically to drive the base 140 to rise and fall, and the first belt in the second driving member 142 is arranged horizontally to drive the transverse movement of the transverse seat. The specific structure of the third driving member 143 will not be repeated here.

[0084] It can be seen that by setting the first conveying mechanism 30 to at least two layers, the processing capacity of the first conveying mechanism 30 for the material box 40 containing the stacked sheets is further improved; the first docking line 13 is driven to rise and fall by the first transfer mechanism 14 to achieve docking with the first conveying units 300 at different heights.

[0085] See also Figure 1 As shown, as an embodiment, the material box circulation device also includes a second transfer mechanism 60 and a second conveying mechanism 70, wherein: the second conveying mechanism 70 is configured to cache empty material boxes 40 or convey the cached empty material boxes 40 to the second transfer mechanism 60.

[0086] It can be seen that the automatic circulation of the empty material box 40 is achieved through the cooperation of the second transfer mechanism 60 and the second conveying mechanism 70 .

[0087] As an implementation mode, the second conveying mechanism 70 is disposed below the first conveying mechanism 30 , and the second transfer mechanism 60 is disposed below the first transfer mechanism 10 .

[0088] It can be seen that by arranging the second conveying mechanism 70 and the first conveying mechanism 30 at intervals in the height direction and arranging the first transfer mechanism 10 and the second transfer mechanism 60 at intervals in the height direction, the space in the height direction can be reasonably utilized, the space occupied by the equipment in the horizontal direction can be greatly reduced, and the overall structure is more compact and reasonable; at the same time, the second conveying mechanism 70 is arranged below the first conveying mechanism 30, so that the material box 40 with the stacked sheets is cached or conveyed above the empty material box 40, which can prevent foreign objects from falling on the stacked sheets during the circulation of the material box 40.

[0089] As an implementation mode, the second conveying mechanism 70 is disposed above the first conveying mechanism 30 , and the second transfer mechanism 60 is disposed above the first transfer mechanism 10 .

[0090] It can be seen that by arranging the second conveying mechanism 70 and the first conveying mechanism 30 at intervals in the height direction and arranging the first transfer mechanism 10 and the second transfer mechanism 60 at intervals in the height direction, the space in the height direction can be reasonably utilized, the space occupied by the equipment in the horizontal direction can be greatly reduced, and the overall structure is more compact and reasonable.

[0091] See also Figure 1 and Figure 4 As shown, as an embodiment, the second transfer mechanism 60 includes a second conveying line 61 and a second reversing mechanism 62, wherein: the second reversing mechanism 62 is configured to receive the empty material box 40 conveyed by the second conveying mechanism 70 along the second direction, and after switching the direction of the received empty material box 40, convey it to the second conveying line 61 along the first direction; the second conveying line 61 is configured to receive the empty material box 40 conveyed by the second reversing mechanism 62, and convey the received empty material box 40 along the first direction to a preset position.

[0092] Specifically, the second reversing mechanism 62 includes a third conveyor belt 620 and a fourth conveyor belt 621 that are vertically crossed. The third conveyor belt 620 can be raised and lowered to a high position and a low position relative to the fourth conveyor belt 621. The raising and lowering of the third conveyor belt 620 can be driven by the second cylinder.

[0093] When the third conveyor belt 620 is in a low position, the conveying surface of the third conveyor belt 620 is lower than the conveying surface of the fourth conveyor belt 621. The fourth conveyor belt 621 is configured to receive the empty material boxes 40 conveyed by the second conveying mechanism 70 along the second direction, and convey the received empty material boxes 40 along the second direction to above the third conveyor belt 620; the second cylinder drives the third conveyor belt 620 to rise to a high position, and the third conveyor belt 620 is used to push the empty material boxes 40 on the fourth conveyor belt 621 away from the fourth conveyor belt 621. The third conveyor belt 620 carries the empty material boxes 40 and conveys the empty material boxes 40 along the first direction to the second conveyor line 61.

[0094] It can be seen that, through the cooperation of the second conveyor line 61 and the second reversing mechanism 60 , the empty material box 40 can be reversingly transported, providing a second transport mechanism 60 with a compact structure and a reasonable layout.

[0095] As an embodiment, the second conveying mechanism 70 includes at least two second conveying units 700 arranged side by side along the first direction, the second conveying unit 700 is configured to convey the empty material box 40 along the second direction, the second transfer mechanism 60 also includes a second docking line 63 and a second transfer mechanism 64, the second docking line 63 is configured to receive the empty material box 40 conveyed by the second conveying unit 700, and convey the received empty material box 40 to the second reversing mechanism 62, the driving end of the second transfer mechanism 64 is connected to the second docking line 63, and the second transfer mechanism 64 is configured to drive the second docking line 63 to move laterally along the first direction to dock with different second conveying units 700.

[0096] It can be seen that by setting up at least two second conveying units 700, the processing capacity of the second conveying mechanism 70 for caching or conveying empty material boxes 40 is improved; through the cooperation of the second docking line 63 and the second transfer mechanism 64, the second reversing mechanism 62 is docked with different second conveying units 700, which can meet the requirements of efficient and fast-paced circulation of empty material boxes 40.

[0097] As an embodiment, the second conveying mechanism 70 is provided with at least two layers, each layer includes at least two second conveying units 700 arranged in parallel, and the second transfer mechanism 64 is also configured to drive the second docking line 63 to rise and fall to dock the second conveying units 700 at different heights.

[0098] It can be seen that by setting the second conveying mechanism 70 to at least two layers, the processing capacity of the second conveying mechanism 70 for empty material boxes 40 is further improved; the second docking line 63 is driven to rise and fall by the second transfer mechanism 64 to achieve docking with the second conveying units 700 at different heights.

[0099] It should be noted that the second transfer mechanism 64 can have the same structure as the first transfer mechanism 14, and the driving form and principle of the two are the same, and the only difference is the transfer object, which will not be repeated here. Figure 4 As shown, the lateral movement drive in the second transfer mechanism 64 is replaced by a rodless cylinder 641, that is, the rodless cylinder 641 is used to drive the second connecting line 63 to move horizontally, and the lifting and lowering of the second connecting line 63 is still driven by a transmission belt.

[0100] As an embodiment, the second transfer mechanism 60 further includes a lifting mechanism 65 , a driving end of the lifting mechanism 65 is connected to the second conveying line 61 , and the lifting mechanism 65 is configured to drive the second conveying line 61 to move up and down.

[0101] Specifically, the lifting mechanism 65 includes a frame 650, a lifting motor 651, a driving pulley 652, a driven pulley, a synchronous belt 653 and a lifting seat 654. The lifting seat 654 is installed on the frame 650 so that it can be lifted. The driving pulley 652 and the driven pulley are spaced apart in the height direction. The driving end of the lifting motor 651 is connected to the driving pulley 652. The synchronous belt 653 is sleeved on the driving pulley 652 and the driven pulley. The second conveyor line 61 is installed on the lifting seat 654. The lifting seat 654 is fixedly connected to the synchronous belt 653. The lifting motor 651 drives the driving pulley 652 to rotate, thereby driving the synchronous belt 653 to rotate, and then driving the lifting seat 654 to rise and fall.

[0102] It can be seen that by providing the lifting mechanism 65, the lifting function of the second conveyor line 61 is realized to meet different application scenarios.

[0103] As an implementation manner, the second conveyor line 61 is located obliquely below the first conveyor line 11 , and the lifting mechanism 65 is configured to drive the second conveyor line 61 to rise to a position parallel to the first conveyor line 11 .

[0104] It can be seen that the second conveyor line 61 can be driven to rise to a position parallel to the first conveyor line 11 through the lifting mechanism 65, so that the external handling mechanism can place the material box 40 loaded with stacked sheets on the first conveyor line 11 while taking away the empty material box 40 on the second conveyor line 61 and transferring it to the material box receiving station, thereby improving the circulation efficiency of the material box 40.

[0105] See also Figures 1 to 4 As shown, the circulation sequence of the material box 40 containing the stacked sheets by the above-mentioned material box circulation device is:

[0106] S1, the external transport mechanism places the material box 40 containing the stacked sheets on the first conveyor line 11;

[0107] S2, the first conveyor line 11 conveys the received material box 40 containing the laminated sheets to the first reversing mechanism 12 along the first direction;

[0108] S3, the first reversing mechanism 12 switches the direction of the received material box 40 containing the laminated sheets and transports it to the first docking line 13 along the second direction;

[0109] S4, the first docking line 13 conveys the received material box 40 containing the stacked sheets to the corresponding first conveying unit 300 along the second direction for buffering or conveys the first conveying unit 300 to the next process.

[0110] The circulation sequence of the above-mentioned material box circulation device for the empty material box 40 is:

[0111] S1, the second conveying unit 700 conveys the received empty material box 40 to the second docking line 63 along the second direction;

[0112] S2, the second docking line 63 conveys the received empty material box 40 to the second reversing mechanism 62 along the second direction;

[0113] S3, the second reversing mechanism 62 switches the direction of the received empty material box 40 and conveys it to the second conveying line 61 along the first direction;

[0114] S4, the second conveyor line 61 conveys the received empty material box 40 to a preset position along the first direction, and the external conveying mechanism conveys the empty material box 40 at the preset position to the material box receiving station.

[0115] It should be noted that when the first conveying mechanism 30 and the second conveying mechanism 70 are used as cache lines, they can be connected to the AGV.

[0116] The material box circulation device provided in the embodiment of the present application has the following advantages:

[0117] 1) It can realize the automatic circulation of the box with stacked sheets and the empty box with high circulation efficiency, which can meet the production requirements of fast beat.

[0118] 2) An exhaust mechanism is provided, which presses the stacked sheets in the material box, thereby exhausting the air between two adjacent layers of the stacked sheets in the material box, thereby preventing the stacked sheets from scattering during transportation due to incomplete exhaustion of the air between adjacent sheets.

[0119] 3) It can realize automatic detection and marking of unevenly stacked sheets, so as to facilitate the subsequent processing of unevenly stacked material boxes.

[0120] 4) The overall structure is compact and the layout is reasonable.
