[0042] See also Figure 1 An embodiment of the utility model provides a lamination device, comprising a lamination table 100, a plurality of feeding devices 200 and a plurality of lamination manipulators 300. The lamination table 100 can be controlled to move along a first direction X1 and pass through a plurality of lamination stations G. Each lamination station G is provided with a feeding device 200, and each feeding device 200 is used to provide a sheet. Each lamination station G is provided with a lamination manipulator 300. Each lamination manipulator 300 is used to grab a sheet provided by a feeding device 200 at the same lamination station G. When the lamination table 100 moves to any lamination station G, the lamination manipulator 300 at the same lamination station G as the lamination table 100 stacks the grabbed sheet on the lamination table 100.

[0043] In the actual use of the above-mentioned stacking equipment, each loading device 200 provides different types of materials, and the stacking platform 100 passes through each stacking station G in a set order. When the stacking platform 100 arrives at any stacking station G, the stacking robot 300 at the stacking station G stacks the grabbed materials on the stacking platform 100, that is, different types of materials are stacked on the stacking platform 100 in a certain order, so as to form a stacked battery cell on the stacking platform 100. In this way, according to the structure of the stacked battery cell currently produced (that is, the type of materials required), the stacking platform 100 can be controlled to selectively move to part or all of the stacking stations G for stacking, so that it can be compatible with the production of stacked batteries with more types of materials required, and it can also be compatible with the production of two or more stacked batteries with different types of materials required, which is conducive to better adapting to the production of solid-state batteries.

[0044] Specifically in the embodiment, each lamination station G is provided with two feeding devices 200, and the two feeding devices 200 are respectively located on both sides of the lamination station G in the second direction X2, and the second direction X2 is perpendicular to the first direction X1. In this way, two feeding devices 200 are arranged in each lamination station G, and the number of feeding devices 200 is greatly increased without increasing the number of lamination stations G, so that more types of sheets can be stacked, and the compatibility of the lamination equipment is further improved. In addition, the two feeding devices 200 in the same lamination station G are respectively arranged on both sides of the lamination station G in the second direction X2, so as to make full use of the space of the lamination equipment in the second direction X2, reduce the space occupied by the lamination equipment in the first direction X1, make the structure more compact, and improve the space utilization rate.

[0045] It should be noted that two stacking robots 300 may be provided at each stacking station G. At the same stacking station G, the sheets provided by the two loading devices 200 are sucked by the two stacking robots 300 and stacked on the stacking table 100. Of course, in other embodiments, only one stacking robot 300 is provided at each stacking station G. At the same stacking station G, the sheets provided by the two loading devices 200 are sucked by the same stacking robot 300 and stacked on the stacking table 100.

[0046] Specifically in the embodiment, the stacking table 100 can also move along the first direction X1 to the loading and unloading station F. The stacking equipment also includes a jig loading device 400 and a jig loading manipulator 500 arranged at the loading and unloading station F. The jig loading device 400 is used to provide a lower clamping plate and an upper clamping plate, and the lower clamping plate and the upper clamping plate are used to clamp the stacked battery cells. The jig loading manipulator 500 is used to transfer the lower clamping plate provided by the jig loading device 400 to the stacking table 100 located at the loading and unloading station F, and transfer the upper clamping plate provided by the jig loading device 400 to the stacked battery cells on the stacking table 100 located at the loading and unloading station F, so that the stacked battery cells on the stacking table 100 are clamped by the lower clamping plate and the upper clamping plate, that is, the stacked battery cells are clamped, so as to facilitate the subsequent edge sealing of the stacked battery cells.

[0047] Optionally, the magnetic attraction force generated by the magnetic attraction member can make the lower clamping plate and the upper clamping plate attract each other to clamp the laminated battery core between them. Of course, the lower clamping plate and the upper clamping plate can also be clamped by other locking structures, which are not limited here.

[0048] Furthermore, the lamination equipment further includes a cell unloading device 600 and a cell unloading robot 700 arranged at the loading and unloading station F. The cell unloading robot 700 is used to transfer the lower clamping plate, the laminated cell and the lower clamping plate on the lamination table 100 arriving at the loading and unloading station F as a whole to the cell unloading device 600, thereby realizing unloading of the laminated cell.

[0049] Thus, in actual use, the stacking platform 100 first moves to the loading and unloading station F, and the jig loading robot 500 transfers the lower clamping plate provided by the jig loading device 400 to the stacking platform 100. Then, the stacking platform 100 moves to some or all of the stacking stations G, and when reaching any of the stacking stations G, the corresponding stacking robot 300 is used to stack the grabbed sheets on the lower clamping plate on the stacking platform 100, thereby forming a stacked battery cell on the lower clamping plate. Then, the stacking platform 100 moves to the loading and unloading station F, and the jig loading robot 500 transfers the lower clamping plate provided by the jig loading device 400 to the stacked battery cell of the stacking platform 100, so that the stacked battery cell is clamped and fixed by the lower clamping plate and the upper clamping plate. Then, the battery cell unloading robot 700 transfers the lower clamping plate, the stacked battery cell and the lower clamping plate on the stacking platform 100 as a whole to the battery cell unloading device 600.

[0050] Furthermore, the jig loading device 400 and the battery cell unloading device 600 are respectively located on both sides of the loading and unloading station F in the second direction X2, thereby fully utilizing the space of the lamination equipment in the second direction X2 and reducing the space occupied by the lamination equipment in the first direction X1, making the structure more compact and improving space utilization.

[0051] Furthermore, the lamination equipment also includes a slide rail 800 and a translation drive member (not shown). The slide rail 800 extends longitudinally along the first direction X1, and the lamination platform 100 is arranged on the slide rail 800 and is movable along the slide rail 800. The driving end of the translation drive member is connected to the lamination platform 100, so that the translation drive member can drive the lamination platform 100 to move along the slide rail 800, thereby enabling the lamination platform 100 to pass through each lamination station G and loading and unloading station F. Optionally, the translation drive member can adopt an electric cylinder. Of course, in other embodiments, the translation drive member can also adopt other types of linear drive modules, as long as it can drive the lamination platform 100 to move along the slide rail 800 to reach each lamination station G and loading and unloading station F, which is not limited here.

[0052] It should be noted that the number of the lamination stations G can be two, three, four, five or six, etc., which is not limited here. For ease of understanding, the following description is given by taking five lamination stations G as an example.

[0053] Specific to Figure 1In the illustrated embodiment, the number of stacking stations G is five, and the five stacking stations G are respectively the first stacking station G1, the second stacking station G2, the third stacking station G3, the fourth stacking station G4 and the fifth stacking station G5 which are arranged in sequence along the first direction X1. Each stacking station G is provided with two loading devices 200, so a total of ten loading devices 200 are included. Each loading device 200 provides a material sheet, and ten loading devices 200 can provide ten types of materials. In actual use, the stacking table 100 moves between the stacking stations G, and can selectively stack all or part of the materials provided by the loading devices 200 onto the stacking table 100, so as to adapt to the production of stacked cells with different types of required materials.

[0054] Optionally, the two feeding devices 200 located at the first lamination station G1 provide the first aluminum-plastic film and the second aluminum-plastic film, respectively. The two feeding devices 200 located at the second lamination station G2 provide the first anode sheet and the FEP sheet, respectively. The two feeding devices 200 located at the third lamination station G3 provide the second anode sheet and the first solid electrolyte sheet, respectively. The two feeding devices 200 at the fourth lamination station G4 provide the second solid electrolyte sheet and the guide frame sheet, respectively. The two feeding devices 200 at the fifth lamination station G5 provide the bottom coating sheet and the cathode sheet, respectively.

[0055] In some embodiments, first, the stacking platform 100 moves along the first direction X1 to the loading and unloading station F, and the jig loading robot 500 transfers the lower clamping plate provided by the jig loading device 400 to the stacking platform 100. Then, the stacking platform 100 moves along the first direction X1 to the first stacking station G1, and the corresponding stacking robot 300 stacks the first aluminum-plastic film provided by the loading device 200 onto the lower clamping plate on the stacking platform 100. Then, the stacking platform 100 moves along the first direction X1 to the second stacking station G2, and the corresponding stacking robot 300 stacks the FEP sheet provided by the loading device 200 onto the first aluminum-plastic film on the stacking platform 100, and the corresponding stacking robot 300 stacks the first anode sheet provided by the loading device 200 onto the first aluminum-plastic film on the stacking platform 100. Then, the stacking platform 100 moves along the first direction X1 to the third stacking station G3, and the corresponding stacking robot 300 stacks the first solid electrolyte sheet provided by the loading device 200 onto the first anode sheet on the stacking platform 100. Then, the stacking platform 100 moves along the first direction X1 to the fourth stacking station G4, and the corresponding stacking robot 300 stacks the guide frame sheet provided by the loading device 200 onto the first solid electrolyte sheet on the stacking platform 100. Then, the stacking platform 100 moves along the first direction X1 to the fifth stacking station G5, and the corresponding stacking robot 300 stacks the cathode sheet provided by the loading device 200 onto the guide frame sheet on the stacking platform 100, and the corresponding stacking robot 300 stacks the bottom coating sheet provided by the loading device 200 onto the cathode sheet on the stacking platform 100. Then, the lamination stage 100 moves along the first direction X1 to the fourth lamination station G4, and the corresponding lamination robot 300 stacks the second solid electrolyte sheet provided by the loading device 200 onto the bottom coating sheet on the lamination stage 100. Then, the lamination stage 100 moves along the first direction X1 to the third lamination station G3, and the corresponding lamination robot 300 stacks the second anode sheet provided by the loading device 200 onto the second solid electrolyte sheet on the lamination stage 100. Then, the lamination stage 100 moves along the first direction X1 to the first lamination station G1, and the corresponding lamination robot 300 stacks the second aluminum-plastic film provided by the loading device 200 onto the second anode sheet on the lamination stage 100. At this time, the layers of sheets stacked on the lamination stage 100 form a first type of laminated battery cell. That is to say, the first type of laminated battery cell is formed by stacking ten sheets of material, namely, the first aluminum-plastic film, the FEP sheet, the first anode sheet, the first solid electrolyte sheet, the guide frame sheet, the cathode sheet, the bottom coating sheet, the second solid electrolyte sheet, the second anode sheet and the second aluminum-plastic film. Then, the laminating table 100 moves along the first direction X1 to the loading and unloading station F, and the jig loading manipulator 500 transfers the upper clamping plate provided by the jig loading device 400 to the laminated battery cell on the laminating table 100, so that the lower clamping plate and the upper clamping plate jointly clamp the laminated battery cell therebetween.Finally, the battery cell unloading robot 700 transfers the lower clamping plate, the laminated battery cells and the upper clamping plate on the lamination table 100 as a whole to the battery cell unloading device 600, thereby realizing the unloading of the laminated battery cells.

[0056] It should be noted that it is not limited to stacking all the sheets provided by the loading device 200 on the stacking table 100. In other embodiments, only some of the sheets provided by the loading device 200 can be stacked on the stacking table 100. Specifically, first, the stacking table 100 moves to the loading and unloading station F along the first direction X1, and the jig loading robot 500 transfers the lower clamping plate provided by the jig loading device 400 to the stacking table 100. Then, the stacking table 100 moves to the second stacking station G2 along the first direction X1, and the corresponding stacking robot 300 stacks the first anode sheet provided by the loading device 200 on the lower clamping plate on the stacking table 100. Then, the stacking table 100 moves to the third stacking station G3 along the first direction X1, and the corresponding stacking robot 300 stacks the first solid electrolyte sheet provided by the loading device 200 on the first anode sheet on the stacking table 100. Then, the lamination stage 100 moves to the fourth lamination station G4 along the first direction X1, and the corresponding lamination robot 300 stacks the guide frame sheet provided by the loading device 200 onto the first solid electrolyte sheet on the lamination stage 100. Then, the lamination stage 100 moves to the fifth lamination station G5 along the first direction X1, and the corresponding lamination robot 300 stacks the cathode sheet provided by the loading device 200 onto the guide frame sheet on the lamination stage 100, and the corresponding lamination robot 300 stacks the bottom coating sheet provided by the loading device 200 onto the cathode sheet on the lamination stage 100. Then, the lamination stage 100 moves to the fourth lamination station G4 along the first direction X1, and the corresponding lamination robot 300 stacks the second solid electrolyte sheet provided by the loading device 200 onto the bottom coating sheet on the lamination stage 100. At this time, the layers of sheets stacked on the lamination stage 100 form a second type of laminated battery cell. That is to say, the second type of laminated battery cell is formed by stacking six types of sheets, namely, the first anode sheet, the first solid electrolyte sheet, the guide frame sheet, the cathode sheet, the bottom coating sheet, and the second solid electrolyte sheet. Then, the lamination table 100 moves along the first direction X1 to the loading and unloading station F, and the jig loading robot 500 transfers the upper clamping plate provided by the jig loading device 400 to the laminated battery cell on the lamination table 100, so that the lower clamping plate and the upper clamping plate jointly clamp the laminated battery cell between the two. Finally, the battery cell unloading robot 700 transfers the lower clamping plate, the laminated battery cell and the upper clamping plate on the lamination table 100 as a whole to the battery cell unloading device 600, thereby realizing the unloading of the laminated battery cell.

[0057] In the embodiment of the present application, some of the loading devices 200 use the first loading device 200a, and some of the loading devices 200 use the second loading device 200b. Figure 2 and Figure 3 As shown, the first loading device 200a stores a plurality of material boxes A, each of which contains a plurality of stacked sheets. The first loading device 200a is used to push the material boxes A to the material taking position C one by one, so that the corresponding stacking robot 300 can take away the sheets in the material box A at the material taking position C, that is, to realize the loading of the sheets. Figure 4 As shown, the second loading device 200b is used to install the material roll, unwind the material strip E on the material roll, and cut the material strip E section by section to form sheets, so that the corresponding stacking robot 300 can take away the sheets, that is, to realize the loading of the sheets.

[0058] Optionally, the first feeding device 200a is suitable for the sheet itself not being easily deformed, and can ensure that each layer of the sheet is in a flat state when stacked in the material box A, so that the stacking robot 300 can smoothly absorb the sheet stacked on the top layer in the material box A. For example, the seven feeding devices 200 respectively used to provide the first anode sheet, the first solid electrolyte sheet, the guide frame sheet, the cathode sheet, the bottom coating sheet, the second solid electrolyte sheet and the second anode sheet adopt the above-mentioned first feeding device 200a.

[0059] Optionally, the second feeding device 200b is suitable for the case where the sheet itself is easily deformed, and the sheet stacked in the material box A is uneven due to bending, making it difficult for the stacking robot 300 to absorb the sheet and unable to take the sheet. For example, three feeding devices 200 respectively used to provide the first aluminum-plastic film, the second aluminum-plastic film and the FEP sheet use the above-mentioned second feeding device 200b.

[0060] See also Figure 2 and Figure 3 As shown, in the embodiment of the present application, the first loading device 200a includes a material bin 10a, a material ejection mechanism 20a and a material pushing mechanism (not shown). The material bin 10a is used to carry a plurality of material boxes A, and each material box A is stacked and placed in the material bin 10a. The material pushing mechanism includes a gripping portion 31a for grabbing or releasing the material box A, and the gripping portion 31a can be controlled to move along the second direction X2 to drive the grabbed material box A to transfer between the material bin 10a and the material taking station C. The material ejection mechanism 20a includes a material ejection driving member 21a and a material ejection member 22a connected to the driving end of the material ejection driving member 21a. The material lifting drive 21a is used to drive the material lifting member 22a to lift each material box A in the material bin 10a, so that the material box A located at the top layer and the grasping portion 31a are opposite to each other in the second direction X2, so that the grasping portion 31a can grasp a material box A stacked on the top layer when it moves to the material bin 10a along the second direction X2. It should be noted that the material lifting drive 21a can adopt an electric cylinder. Of course, in other embodiments, the material lifting drive 21a can also adopt other linear drive modules, as long as it can drive the material lifting member 22a to rise or fall in the vertical direction, which is not limited here.

[0061] When the first loading device 200a is actually used, a plurality of material boxes A filled with tablets are stacked and placed in the material bin 10a, and the grabbing portion 31a of the pushing mechanism moves to the material bin 10 along the second direction X2 and grabs a material box A located at the top layer. Then, the grabbing portion 31a of the pushing mechanism moves toward the material picking station C along the second direction X2 until the grabbed material box A is driven to move to the material picking station C. At this time, the stacking robot 300 grabs the tablets in the material box A at the material picking station C and stacks them on the stacking table 100.

[0062] After all the sheets in the material box A at the material taking station C are taken away (the material box A without sheets is an empty material box), the gripping part 31a of the pushing mechanism moves toward the material bin 10a until the empty material box is driven back into the material bin 10a and stacked on the top layer of each material box A. At this time, the gripping part 31a of the pushing mechanism releases the empty material box A. The top empty material box A in the material bin 10a is taken away manually or automatically. Then, the lifting driving member 21a drives the lifting member 22a to move upward, so that the lifting member 22a lifts each material box A in the material bin 10a until the topmost material box A in each material box A reaches a height relative to the gripping part 31a in the second direction X2. Then, the grabbing portion 31a of the pushing mechanism grabs the material box A located at the top, and moves toward the material taking station C along the second direction X2, until the grabbing portion 31a drives the grabbed material box A to move to the material taking station C.

[0063] In this way, each time after all the sheets in the material box A at the material picking station C are used up, the grabbing part 31a pushes the empty material box back to the material bin 10a, and then pulls the material box A storing the sheets to the material picking station C. The loading and unloading process of the material box A is simple and fast. During this process, the stacking equipment does not need to be shut down and can perform stacking operations normally, which is beneficial to improving production efficiency.

[0064] It should be noted that since only one material box A is transferred to the material picking station C each time, and the empty material box is returned to the material bin 10a along the original route, and the material boxes A in the material bin 10a are stacked, it is beneficial to make the structure of the first loading device 200a more compact, thereby greatly reducing the required occupied space.

[0065] Furthermore, a photoelectric sensor 11a is installed on the silo 10a, and the photoelectric sensor 11a is used to detect whether there is a material box A in the silo 10a. If the photoelectric sensor 11a detects that there is no material box A in the silo 10a, an alarm can be issued to remind the operator to load the material box A filled with tablets into the silo 10a in time.

[0066] In some embodiments, the first loading device 200a further includes a support mechanism 50a disposed between the material bin 10a and the material picking station C, and the support mechanism 50a is used to support the material box A moving between the material bin 10a and the material picking station C. After the grabbing portion 31a grabs the material box A in the material bin 10a, it moves along the second direction X2, thereby driving the material box A in the material bin 10a to the support mechanism 50a, and moving toward the material picking station C on the support mechanism 50a until reaching the material picking station C. When the material box A in the material picking station C becomes an empty material box, the grabbing portion 31a moves toward the material bin 10a along the second direction X2, thereby driving the empty material box to move toward the material bin 10a on the support mechanism 50a until the empty material box enters the material bin 10a. In this way, the support mechanism 50a is used to support the material box A transferred between the material bin 10a and the material picking station C to prevent the material box A from turning over or even falling.

[0067] Specifically in the embodiment, the support mechanism 50a includes a support frame 51a and a plurality of guide wheels 52a mounted on the support frame 51a. The support frame 51a has a transfer channel (not shown) extending longitudinally along the second direction X2. A plurality of guide wheels 52a are provided on both sides of the transfer channel. The plurality of guide wheels 52a are used to confine the passing material box A within the transfer channel, that is, each guide wheel 52a guides the passing material box A so that the material box A moves along the second direction X2 within the transfer channel. In this way, under the guiding action of each guide wheel 52a, the material box A can accurately enter and exit the material bin 10a and the material retrieving station C, ensuring that the material box A can accurately transfer between the material bin 10a and the material retrieving station C.

[0068] Furthermore, the support frame 51a has two support bars 53a, which are arranged side by side and extend longitudinally along the second direction X2 between the silo 10a and the material-retrieving station C. The two support bars 53a form the above-mentioned transfer channel, which is used to jointly support the material box A passing through. The guide wheels 52a are arranged in two rows, and the guide wheels 52a in each row are arranged at intervals along the second direction X2. The two rows of guide wheels 52a are respectively located on the outside of the two support bars 53a, so that the two rows of guide wheels 52a limit the passing material box A within the transfer channel, avoiding the deviation of the moving trajectory of the material box A, resulting in the inability to accurately enter the silo 10a or the material-retrieving station C.

[0069] Specifically in the embodiment, the material pushing mechanism includes a material pushing movable seat (not shown) and a material pushing driving member 32a. The material pushing movable seat is movably connected to the support frame 51a along the second direction X2. The material pushing driving member 32a is installed on the support frame 51a, and the driving end of the material pushing driving member 32a is connected to the material pushing movable seat, so that the material pushing driving member 32a can drive the material pushing movable seat to move relative to the support frame 51a along the second direction X2. The grabbing portion 31a is installed on the material pushing movable seat, so that the grabbing portion 31a can move along the second direction X2 with the material pushing movable seat, and then the grabbing portion 31a drives the material box A to transfer between the silo 10a and the material picking station C.

[0070] Optionally, the pusher movable seat is installed on the support frame 51a via guide components such as guide rails or guide rods, so that the movement of the pusher movable seat relative to the support frame 51a is guided by guide components such as guide rails or guide rods, so that the movement accuracy of the pusher movable seat along the second direction X2 meets the design requirements.

[0071] Optionally, the grasping portion 31a includes a first clamping jaw cylinder 311a and a first clamping jaw 313a, the first clamping jaw cylinder 311a is installed on the pusher movable seat, and the first clamping jaw 313a is installed at the driving end of the first clamping jaw cylinder 311a. Each material box A has a clamping matching portion A1 for the first clamping jaw 313a to clamp. The first clamping jaw cylinder 311a can drive the first clamping jaw 313a to clamp or release the clamping matching portion A1 on the material box A. Of course, in other embodiments, the grasping portion 31a can also adopt other grasping structures, as long as it can achieve clamping or release of the clamping matching portion A1 on the material box A, which is not limited here.

[0072] In the embodiment of the present application, the first loading device 200a further includes a positioning mechanism 60a arranged at the material picking station C. The positioning mechanism 60a can be controlled to be positioned, matched or separated with the material box A that arrives at the material picking station C. In this way, when the grasping portion 31a grasps the material box A in the material bin 10a and drives the material box A to the material picking station C, the positioning mechanism 60a is controlled to be positioned and matched with the material box A, so that the material box A is positioned and fixed at the material picking station C, which ensures that the position accuracy of the material box A meets the design requirements on the one hand, and avoids the position deviation of the material box A during the process of the stacking robot 300 taking the material sheet.

[0073] Specifically in the embodiment, the positioning mechanism 60a includes a positioning drive member 61a and a positioning pin 62a connected to the driving end of the positioning drive member 61a. A positioning hole capable of being positioned and matched with the positioning pin 62a is provided on each material box A. When the gripping portion 31a drives the material box A to move from the material bin 10a to the material picking station C, the positioning drive member 61a drives the positioning pin 62a to extend toward the material box A, so that the positioning pin 62a is inserted into the positioning hole on the material box A, thereby preventing the material box A from continuing to move at the material picking station C. After all the sheets in the material box A at the material picking station C are taken away, the positioning drive member 61a drives the positioning pin 62a to retract, so that the positioning pin 62a withdraws from the positioning hole on the empty material box A, so that the empty material box A located at the material picking station C can return to the material bin 10a under the drive of the gripping portion 31a.

[0074] Furthermore, the number of positioning mechanisms 60a is set to two, and the two positioning mechanisms 60a are respectively located on the opposite sides of the material box A arriving at the material picking station C, so that the two positioning mechanisms 60a respectively position the material box A from both sides of the material box A, ensuring that the positioning of the material box A is more accurate, and further improving the position accuracy of the material box A.

[0075] In the embodiment of the present application, the first loading device 200a further includes a lifting mechanism 40a, which includes a lifting drive 41a and a lifting member 42a connected to the driving end of the lifting drive 41a. The lifting member 42a is located below the material box A that arrives at the material picking station C. The lifting drive 41a is used to drive the lifting member 42a to move upward, so that the lifting member 42a lifts the material in the material box A that arrives at the material picking station C, so that the stacking robot 300 can accurately absorb the uppermost material in the material box A.

[0076] Further, the lifting member 42a is connected to the support frame 51a in a manner that it can be lifted and moved, the lifting drive member 41a is installed on the support frame 51a, and the driving end of the lifting drive member 41a is connected to the lifting member 42a, so that the lifting drive member 41a can drive the lifting member 42a to rise or fall relative to the support frame 51a. Optionally, the lifting drive member 41a can adopt an electric cylinder. Of course, in other embodiments, the lifting drive member 41a can also adopt other types of linear drive modules, as long as it can drive the lifting member 42a to rise or fall, which is not limited here.

[0077] Optionally, the lifting member 42a is installed on the support frame 51a via guide components such as guide rails or guide rods, so that the movement of the lifting member 42a relative to the support frame 51a is guided by the guide components such as guide rails or guide rods, which is beneficial to improving the movement accuracy of the lifting member 42a when rising or falling.

[0078] It should be noted that, in actual use, after the gripping portion 31a drives the material box A to the material picking station C, the positioning mechanism 60a is used to position the material box A. Then, the stacking robot 300 moves to the top of the material box A located at the material picking station C, and gradually descends until the stacking robot 300 absorbs the topmost sheet of material in the material box A located at the material picking station C. Then, the stacking robot 300 rises, thereby driving the absorbed sheet to rise together. Since the two adjacent layers of sheets in the material box A are attached to each other, there is a certain bonding force between the two. When the stacking robot 300 absorbs the topmost sheet of material and rises, the topmost sheet of material will also rise with the sheet of the next layer, causing the stacking robot 300 to take away two or more sheets of material at a time.

[0079] In order to ensure that the stacking robot 300 only takes away one sheet at a time, in an embodiment of the present application, the first loading device 200a also includes an anti-double sheet mechanism (not shown). The anti-double sheet mechanism includes a mounting frame 71a and an anti-double sheet member 72a mounted on the mounting frame 71a. The anti-double sheet member 72 is located above the material box A that reaches the material taking station C. The anti-double sheet member 72a includes a blowing member and / or a brush. In this way, in the process of the stacking robot 300 sucking the sheet and moving upward, the blowing member is used to blow air to the sheet sucked by the stacking robot 300 and / or the brush is used to scrape the sheet sucked by the stacking robot 300, so that the top sheet is separated from the next sheet, thereby ensuring that the stacking robot 300 can only take away one sheet at a time (that is, it can only take away the top sheet in the material box A).

[0080] Specifically in the embodiment, the position of the mounting frame 71a in the vertical direction is adjustable, so as to adjust the height of the double-stretching prevention member 72a, thereby ensuring that the double-stretching prevention effect of the double-stretching prevention member 72a is better.

[0081] Furthermore, the mounting frame 71a is connected to the support frame 51a in a manner that it can be lifted and moved. The double-stretching prevention mechanism also includes an adjustment drive member 73a installed on the support frame 51a, and the driving end of the adjustment drive member 73a is connected to the mounting frame 71a, so that the adjustment drive member 73a can drive the mounting frame 71a to move in the vertical direction relative to the support frame 51a (i.e., rise or fall), that is, to adjust the position of the mounting frame 71a in the vertical direction, thereby achieving the purpose of adjusting the height of the double-stretching prevention member 72a.

[0082] Optionally, the adjusting driving member 73a may be an electric cylinder. Of course, in other embodiments, the adjusting driving member 73a may also be other types of linear driving modules, as long as it can drive the mounting frame 71a to move in the vertical direction to adjust the position, which is not limited here.

[0083] Optionally, the mounting frame 71a can be installed on the support frame 51a via guide components such as guide rails or guide columns, so that the movement of the mounting frame 71a relative to the support frame 51a in the vertical direction is guided by the guide components such as guide rails or guide columns, so that the movement accuracy of the mounting frame 71a meets the design requirements.

[0084] Specifically in the embodiment, the support frame 51a has a bad position D for placing a waste collection box B. When the sheet sucked by the stacking robot 300 is a bad sheet, the stacking robot 300 transfers the bad sheet to the waste collection box B located at the bad position D. Optionally, the bad position D is located on the side of the material taking station C away from the silo 10.

[0085] See also Figure 4 As shown, in the embodiment of the present application, the second feeding device 200b includes an unwinding component 10b, a cutting component 20b, an adsorption component 30b and a material pulling component 40b. The unwinding component 10b is used to unwind and output the material strip E to the downstream. The cutting component 20b is arranged downstream of the unwinding component 10b, and is used to cut off the material strip E passing through. The adsorption component 30b is arranged downstream of the cutting component 20b, and includes an adsorption platform 31b for adsorbing the material strip E passing through. The material pulling component 40b is used to clamp the material strip E at the cutting component 20b, and pull the clamped material strip E to the adsorption platform 31b.

[0086] In the actual use of the second loading device 200b, the unwinding component 10b unwinds the material strip E to the cutting component 20b. First, the material pulling component 40b moves to the cutting component 20b and clamps the starting end of the material strip E. Then, the material pulling component 40b moves to the adsorption platform 31b until a certain length of the material strip E is pulled onto the adsorption platform 31b. Then, the material pulling component 40b releases the starting end of the material strip E, and the adsorption platform 31b adsorbs and fixes the material strip E thereon. Then, the cutting component 20b cuts off the material strip E passing through, and at this time, the part of the material strip E adsorbed and fixed by the adsorption platform 31b is cut off, and this part is the material sheet. Then, the adsorption platform 31b stops adsorbing the material sheet, and the corresponding stacking robot 300 absorbs the material sheet on the adsorption platform 31b. Then, the stacking robot 300 stacks the absorbed material sheets onto the stacking table 100.

[0087] In this way, the second loading device 200b in the present application pulls out a certain length of the material strip E to the adsorption platform 31b each time through the material pulling component 40b, and cuts it with the cutting component 20b, so as to form a sheet of material of the required length on the adsorption platform 31b for the stacking robot 300 to take away and stack. Compared with the prior art, the present application directly cuts the material strip E to form a sheet, and the sheet is adsorbed and fixed by the adsorption platform 31b, so that the sheet remains flat, ensuring that the stacking robot 300 can easily take the sheet, which greatly improves the stacking efficiency.

[0088] Specifically in the embodiment, the second loading device 200b also includes a mounting seat 80b and a deviation correction driving member 90b. The unwinding assembly 10b is arranged on the mounting seat 80b, so that the unwinding assembly 10b and the material strip E unwinded and output by the unwinding assembly 10b can move with the mounting seat 80b. The mounting seat 80b is connected to the driving end of the deviation correction driving member 90b, so that the deviation correction driving member 90b can drive the mounting seat 80b to move, thereby driving the unwinding assembly 10b and the material strip E unwinded and output by the unwinding assembly 10b to correct the deviation, which is beneficial to improve the position accuracy of the material sheet formed on the adsorption platform 31b later, and ensure that the stacking robot 300 can accurately take the sheet.

[0089] Furthermore, the moving direction of the mounting seat 80b is parallel to the width direction of the material strip E unwound by the unwinding assembly 10b, that is, the deflection correction drive 90b can drive the mounting seat 80b to move along the width direction of the material strip E, thereby driving the material strip E to adjust its position along its width direction (i.e., deflection correction), which is beneficial to improving the position accuracy of the material sheet subsequently formed on the adsorption platform 31b. It should be noted that the deflection correction drive 90b can be a linear motor, and of course, it can also be other types of linear drive modules, as long as it can drive the mounting seat 80b to move along the width direction of the material strip E, and it is not limited here.

[0090] Furthermore, the second loading device 200b further includes a guide rail 81b extending longitudinally along the width direction of the material strip E. A slider 82b is mounted on the mounting seat 80b, and the slider 82b is disposed on the guide rail 81b and is movable along the guide rail 81b. In this way, the movement of the mounting seat 80b is guided by the movement of the slider 82b along the guide rail 81b, so that the deviation correction movement of the material strip E is more accurate and reliable.

[0091] Specifically in the embodiment, the second feeding device 200b also includes a correction sensor 50b arranged between the cutting component 20b and the unwinding component 10b. The correction sensor 50b is used to detect the position of the passing material strip E in its own width direction. The correction sensor 50b is communicatively connected with the correction drive 90b, so that the correction drive 90b can drive the mounting seat 80b to move according to the detection result of the correction sensor 50b, thereby driving the material strip E to correct the deviation. In this way, when the correction sensor 50b detects that there is a deviation in the position of the material strip E in its own width direction, the correction drive 90b controls the mounting seat 80b to move along the width direction of the material strip E, thereby driving the material strip E to adjust its position along its own width direction (i.e., correct the deviation).

[0092] In the embodiment of the present application, the unwinding assembly 10b includes an unwinding mechanism 11b and a buffer mechanism 12b, both of which are mounted on the above-mentioned mounting seat 80b. The unwinding mechanism 11b is used to unwind and output the material strip E downstream. The buffer mechanism 12b is arranged downstream of the unwinding mechanism 11b, and is used to feed the material strip E for winding and buffering the material strip E. In this way, the material strip E is buffered by the buffer mechanism 12b, so that when the pulling assembly 40b pulls the material strip E downstream, the material strip E buffered by the buffer mechanism 12b is consumed, thereby avoiding directly pulling the material strip E on the unwinding mechanism 11b, thereby reducing the risk of breaking the material strip E.

[0093] Furthermore, the unwinding assembly 10b further includes a first dust removal mechanism 13b and a second dust removal mechanism 14b arranged between the unwinding mechanism 11b and the buffer mechanism 12b. The first dust removal mechanism 13b and the second dust removal mechanism 14b are both arranged on the above-mentioned mounting seat 80b and are respectively located on both sides of the passing material belt E, so as to remove dust from the surfaces of both sides of the material belt E respectively, and avoid dust on the surface of the subsequently formed sheet.

[0094] Furthermore, the unwinding assembly 10b further includes a static electricity removal mechanism arranged between the unwinding mechanism 11b and the buffer mechanism 12b. The static electricity removal mechanism is arranged on the above-mentioned mounting seat 80b and is used to eliminate static electricity on the passing material belt E. Optionally, the static electricity removal mechanism can be arranged on the first dust removal mechanism 13b and / or the second dust removal mechanism 14b.

[0095] In some embodiments, the cutting assembly 20b includes an upper cutter 21b, a lower cutter 22b and a cutting drive 23b. The upper cutter 21b and the lower cutter 22b are arranged opposite to each other, and a cutting channel through which the material supply tape E passes is formed between the upper cutter 21b and the lower cutter 22b. The upper cutter 21b is installed at the driving end of the cutting drive 23b, so that the cutting drive 23b can drive the upper cutter 21b to move closer to or away from the lower cutter 22b to cut off the material tape E passing through the cutting channel. In this way, when it is necessary to cut the material tape E, first, the cutting drive 23b drives the upper cutter 21b to gradually move closer to the lower cutter 22b until it cooperates with the lower cutter 22b to cut off the material tape E passing through. Then, the cutting drive 23b drives the upper cutter 21b to move away from the lower cutter 22b until it returns to the initial position. Optionally, the cutting drive 23b can use a cylinder.

[0096] In some embodiments, the second feeding device 200b also includes a material pressing assembly 60b arranged on the upstream side of the cutting assembly 20b (i.e., the side of the cutting assembly 20b away from the adsorption platform 31b). The material pressing assembly 60b includes a pressing plate 61b, a pad 62b, and a material pressing driving member 63b. The pressing plate 61b and the pad 62b are arranged relative to each other, and a material pressing channel through which the feed belt E passes is formed between the two. The driving end of the material pressing driving member 63b is connected to the pressing plate 61b so that the material pressing driving member 63b can drive the pressing plate 61b to move close to or away from the pad 62b. In this way, before the pulling assembly 40b clamps the starting end of the material belt E at the cutting assembly 20b and pulls the material belt E to move toward the adsorption platform 31b, the material pressing driving member 63b drives the pressing plate 61b to move away from the pad 62b, so that the pressing plate 61b and the pad 62b release the material belt E. Before the cutting assembly 20b cuts the material strip E, the material pressing driving member 63b drives the pressing plate 61b to move close to the pad 62b until the material strip E is pressed and fixed on the pad 62b. That is, before cutting, the material strip E upstream of the cutting position is pressed and fixed on the pad 62b by the pressing plate 61b, and the material strip E downstream of the cutting position is adsorbed and fixed by the adsorption platform 31b, which is conducive to improving the cutting quality. Optionally, the material pressing driving member 63b can be a cylinder.

[0097] In some embodiments, the second loading device 200b further includes a dust removal component 70b disposed at the cutting component 20b. The dust removal component 70b is used to absorb dust generated by the cutting component 20b cutting the material strip E, thereby preventing dust from being present on the subsequently formed material sheets.

[0098] Furthermore, the dust suction port of the dust removal component 70b is arranged at the lower cutting knife 22b, so that the dust removal component 70b can easily absorb the dust generated by cutting the material strip E.

[0099] In some embodiments, the adsorption assembly 30b also includes a lifting drive 32b. The adsorption platform 31b is installed at the driving end of the lifting drive 32b, and the lifting drive 32b is used to drive the adsorption platform 31b to move up or down. In this way, when there is no sheet on the adsorption platform 31b, the lifting drive 32b drives the adsorption platform 31b to descend. On the one hand, the height of the adsorption platform 31b is convenient for the pulling assembly 40b to move and pull the material. On the other hand, it is convenient to make the height positions of the adsorption platform 31b, the pad 62b and the lower cutter 22b basically consistent, which is beneficial to improve the cutting quality and the position accuracy of the sheet. When there is a sheet on the adsorption platform 31b, the lifting drive 32b drives the adsorption platform 31b to rise, so that the stacking robot 300 can absorb the sheet on the adsorption platform 31b, which is beneficial to further reduce the difficulty of the stacking robot 300 to take the sheet. Optionally, the lifting drive 32b can use a cylinder.

[0100] In some embodiments, the material pulling assembly 40b includes a moving seat 41b, a moving driving member 42b, and a clamping mechanism 43b. The moving seat 41b is connected to the driving end of the moving driving member 42b, and the clamping mechanism 43b is installed on the moving seat 41b. The clamping mechanism 43b can clamp or release the material strip E in a controlled manner. The moving driving member 42b is used to drive the moving seat 41b to move, so as to drive the clamping mechanism 43b to move between the cutting assembly 20b and the side of the adsorption platform 31b away from the cutting assembly 20b, so that the clamping mechanism 43b clamps the starting end of the material strip E at the cutting assembly 20b, and pulls the material strip E onto the adsorption platform 31b. In this way, when a sheet is needed on the adsorption platform 31b, first, the moving driving member 42b drives the moving seat 41b to move toward the cutting assembly 20b, thereby driving the clamping mechanism 43b to move from the side of the adsorption platform 31b away from the cutting assembly 20b to the side of the adsorption platform 31b close to the cutting assembly 20b, and clamps the starting end of the material strip E located at the cutting assembly 20b; then, the moving driving member 42b drives the moving seat 41b to move away from the cutting assembly 20b until driving the clamping mechanism 43b to move to the side of the adsorption platform 31b close to the cutting assembly 20b. b moves to the side of the adsorption platform 31b away from the cutting component 20b, thereby pulling out a certain length of the material strip E to the adsorption platform 31b; then, the material pressing drive 63b drives the pressing plate 61b to press the material strip E onto the pad 62b, the clamping mechanism 43b releases the material strip E, and the adsorption platform 31b adsorbs and fixes the material strip E thereon; then, the upper cutter 21b and the lower cutter 22b of the cutting component 20b cut off the passing material strip E, and the material strip E located on the adsorption platform 31b at this time is the material sheet.

[0101] It should be noted that the moving driving member 42b may be an electric cylinder, or other types of linear modules, as long as it can drive the moving seat 41b to move, and is not limited here.

[0102] Optionally, the clamping mechanism 43b includes a second clamping jaw cylinder 431b and a second clamping jaw 433b, the second clamping jaw cylinder 431b is mounted on the movable base 41b, and the second clamping jaw 433b is mounted on the driving end of the second clamping jaw cylinder 431b. The second clamping jaw cylinder 431b is used to drive the second clamping jaw 433b to clamp or release the material strip E.

[0103] Combine the following Figure 4 The working process of the second loading device 200b is described as follows:

[0104] First, the moving driving member 42b drives the moving base 41b to move from right to left, thereby driving the second clamping claw 433b of the clamping mechanism 43b to move to the cutting assembly 20b.

[0105] Then, the second clamping jaw cylinder 431b of the clamping mechanism 43b drives the second clamping jaw 433b to clamp the starting end of the material strip E. Then, the moving driving member 42b drives the moving base 41b to move from left to right, thereby driving the second clamping jaw 433b to move to the side of the adsorption platform 31b away from the cutting assembly 20b, so as to pull out a certain length of the material strip E onto the adsorption platform 31b.

[0106] Then, the material pressing driving member 63b drives the pressing plate 61b to press the material strip E onto the backing plate 62b, and the second clamping jaw cylinder 431b of the clamping mechanism 43b drives the second clamping jaw 433b to release the material strip E, and the adsorption platform 31b adsorbs and fixes the material strip E.
