[0048] Referring to FIG. 1, an embodiment of the present application provides a laminating device, which includes a laminating table 100, a plurality of feeding devices 200 and a plurality of laminating robots 300. The laminating table 100 is controllably movable along a first direction X1 and passes through a plurality of laminating stations G. Each laminating station G is arranged with a feeding device 200, and each feeding device 200 is used to provide a piece of material. Each laminating station G is arranged with a laminating robot 300. Each laminating robot 300 is used to grab the piece of material provided by the feeding device 200 in the same laminating station G. When the laminating table 100 moves to any laminating station G, the laminating robot 300 in the same laminating station G as the laminating table 100 will stack the grabbed piece of material on the laminating table 100.

[0049] In actual use, the laminating device described above provides different types of pieces of material by each feeding device 200, and the laminating table 100 passes through each laminating station G according to a set order. When the laminating table 100 reaches any laminating station G, the laminating robot 300 at the laminating station G will stack the grabbed piece of material on the laminating table 100, that is, different types of pieces of material are stacked on the laminating table 100 in a certain order, so as to form a laminated battery cell on the laminating table 100. In this way, the laminating table 100 can be selectively moved to part or all of the laminating stations G for laminating according to the structure of the laminated battery cell currently produced (i.e. the required types of pieces of material), so as to be compatible with the production of laminated battery cells with more required types of pieces of material, and be compatible with the production of two or more laminated battery cells with different required types of pieces of material, which is conducive to better adapting to the production of solid-state batteries.

[0050] Specifically, in the embodiments, two feeding devices 200 are arranged at each lamination station G, and the two feeding devices 200 are respectively arranged at two sides of the lamination station G in the second direction X2 which is perpendicular to the first direction X1. In this way, two feeding devices 200 are arranged at each lamination station G, which greatly increases the number of feeding devices 200 without increasing the lamination stations G, so that more types of laminates can be stacked, and the compatibility of the lamination device is further improved. Moreover, the two feeding devices 200 at the same lamination station G are arranged at two sides of the lamination station G in the second direction X2, so that the space of the lamination device in the second direction X2 is fully utilized, the space of the lamination device in the first direction X1 is reduced, the structure is more compact, and the space utilization is improved.

[0051] It should be noted that two lamination robots 300 can be arranged at each lamination station G. At the same lamination station G, the laminates provided by the two feeding devices 200 are respectively sucked and stacked on the lamination table 100 by the two lamination robots 300. Of course, in other embodiments, only one lamination robot 300 is arranged at each lamination station G. At the same lamination station G, the laminates provided by the two feeding devices 200 are all sucked and stacked on the lamination table 100 by the same lamination robot 300.

[0052] Specifically, in the embodiments, the lamination table 100 can also move to the feeding and discharging station F in the first direction X1. The lamination device further comprises a jig feeding device 400 and a jig feeding robot 500 arranged at the feeding and discharging station F. The jig feeding 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 laminated battery cell. The jig feeding robot 500 is used to transfer the lower clamping plate provided by the jig feeding device 400 to the lamination table 100 located at the feeding and discharging station F, and transfer the upper clamping plate provided by the jig feeding device 400 to the laminated battery cell on the lamination table 100 located at the feeding and discharging station F, so that the laminated battery cell on the lamination table 100 is clamped by the lower clamping plate and the upper clamping plate, that is, the clamping of the laminated battery cell is realized, so as to facilitate the subsequent edge sealing treatment of the laminated battery cell.

[0053] Optionally, the laminated battery cell between the lower clamping plate and the upper clamping plate can be clamped by the magnetic attraction force generated by the magnetic attraction member. Of course, the lower clamping plate and the upper clamping plate can also clamp the laminated battery cell therebetween by other locking structures, which are not limited herein.

[0054] Further, the lamination device further comprises a battery cell discharging device 600 and a battery cell discharging robot 700 arranged at the feeding and discharging station F. The battery cell discharging robot 700 is used to transfer the lower clamping plate, the laminated battery cell and the lower clamping plate as a whole on the lamination table 100 reaching the feeding and discharging station F to the battery cell discharging device 600, so as to realize the discharging of the laminated battery cell.

[0055] Thus, in actual use, the lamination table 100 first moves to the upper and lower loading and unloading station F, and the jig loading manipulator 500 transfers the lower clamping plate provided by the jig loading device 400 to the lamination table 100. Then, the lamination table 100 moves to the partial or full lamination station G, and when reaching any of the lamination stations G, the lamination manipulator 300 corresponding to the lamination station G is used to stack the grabbed sheet on the lower clamping plate on the lamination table 100, so as to form a laminated battery cell on the lower clamping plate. Then, the lamination table 100 moves to the upper and lower loading and unloading station F, and the jig loading manipulator 500 transfers the lower clamping plate provided by the jig loading device 400 to the laminated battery cell on the lamination table 100, so that the laminated battery cell is clamped and fixed by the lower clamping plate and the upper clamping plate. Then, the battery cell unloading manipulator 700 transfers the lower clamping plate, the laminated battery cell and the lower clamping plate on the lamination table 100 as a whole to the battery cell unloading device 600.

[0056] Further, the jig loading device 400 and the battery cell unloading device 600 are respectively located on both sides of the upper and lower loading and unloading station F in the second direction X2, so as to make full use of the space of the lamination device in the second direction X2, reduce the occupation of the space of the lamination device in the first direction X1, make the structure more compact, and improve the space utilization.

[0057] Further, the lamination device further comprises a slide rail 800 and a translation driving member (not shown in the figure). The slide rail 800 extends longitudinally along the first direction X1, and the lamination table 100 is arranged on the slide rail 800 and is movable along the slide rail 800. The driving end of the translation driving member is connected with the lamination table 100, so that the translation driving member can drive the lamination table 100 to move along the slide rail 800, and thus the lamination table 100 can pass through each lamination station G and the upper and lower loading and unloading station F. Optionally, the translation driving member can adopt an electric cylinder. Of course, in other embodiments, the translation driving member can also adopt other types of linear driving modules, as long as it can drive the lamination table 100 to move along the slide rail 800 to reach each lamination station G and the upper and lower loading and unloading station F, which is not limited herein.

[0058] It should be noted that the number of lamination stations G can be two, three, four, five or six, etc., which is not limited herein. For the convenience of understanding, five lamination stations G are taken as an example for description in the following.

[0059] Specific to the embodiment shown in FIG. 1, the number of the lamination stations G is five, which are first lamination station G1, second lamination station G2, third lamination station G3, fourth lamination station G4 and fifth lamination station G5 arranged in sequence and spaced apart along the first direction X1. Each lamination station G is arranged with two feeding devices 200, so there are totally ten feeding devices 200. Each feeding device 200 provides one kind of material sheet, and ten feeding devices 200 can provide ten kinds of material sheets. In actual use, the lamination table 100 moves between each lamination station G and selectively stacks all or part of the material sheets provided by the feeding devices 200 on the lamination table 100, so as to adapt to the production of lamination battery cells with different required material sheet types.

[0060] Optionally, the two feeding devices 200 located at the first lamination station G1 provide first and second aluminum plastic films respectively. The two feeding devices 200 located at the second lamination station G2 provide first anode sheets and FEP sheets respectively. The two feeding devices 200 located at the third lamination station G3 provide second anode sheets and first solid electrolyte sheets respectively. The two feeding devices 200 located at the fourth lamination station G4 provide second solid electrolyte sheets and guide frame sheets respectively.

The pushing mechanism comprises a grabbing part 31a for grabbing or releasing the box A, and the grabbing part 31a can be controlled to move along the second direction X2 to drive the grabbed box A to transfer between the hopper 10a and the taking station C. The top feeding mechanism 20a comprises a top feeding driving part 21a and a top feeding part 22a connected to the driving end of the top feeding driving part 21a. The top feeding driving part 21a is used to drive the top feeding part 22a to lift each box A in the hopper 10a, so that the box A located at the uppermost layer and the grabbing part 31a are opposite to each other in the second direction X2, and then the grabbing part 31a can grab one box A stacked at the uppermost layer when it moves to the hopper 10a along the second direction X2. It should be noted that the top feeding driving part 21a can be an electric cylinder. Of course, in other embodiments, the top feeding driving part 21a can also use other linear driving modules as long as it can drive the top feeding part 22a to ascend or descend in the vertical direction, which is not limited here.

[0067] The above-mentioned first feeding device 200a, in actual use, a plurality of boxes A filled with pieces are stacked and placed in the hopper 10a, the grabbing part 31a of the pushing mechanism moves to the hopper 10 along the second direction X2 and grabs one box A located at the uppermost layer. Then, the grabbing part 31a of the pushing mechanism moves along the second direction X2 to the taking station C until the grabbed box A is moved to the taking station C. At this time, the stacking manipulator 300 grabs the piece stack in the box A at the taking station C to the stacking table 100.

[0068] When all the pieces in the box A at the taking station C are taken away (the box A without pieces is an empty box), the grabbing part 31a of the pushing mechanism moves towards the hopper 10a until the empty box is brought back into the hopper 10a and stacked at the uppermost layer of each box A. At this time, the grabbing part 31a of the pushing mechanism releases the empty box A. The empty box A at the uppermost layer in the hopper 10a is taken away by manual or automatic way. Then, the top feeding driving part 21a drives the top feeding part 22a to move upward, so that the top feeding part 22a lifts each box A in the hopper 10a until the box A at the uppermost layer in each box A reaches the height opposite to the grabbing part 31a in the second direction X2. Then, the grabbing part 31a of the pushing mechanism grabs the box A at the uppermost layer and moves along the second direction X2 to the taking station C until the grabbing part 31a drives the grabbed box A to move to the taking station C.

[0069] Thus, after all the sheets in the magazine A at the taking station C are used up, the grabbing part 31a pushes the empty magazine back to the magazine bin 10a, and then pulls the magazine A storing sheets to the taking station C, so that the magazine A is loaded and unloaded simply and quickly, and the laminating device does not need to stop during the process, and can normally carry out laminating operation, which is beneficial to improve the production efficiency.

[0070] It should be noted that, since only one magazine A is transferred to the taking station C each time, and the empty magazine returns to the magazine bin 10a along the original path, and the magazines A are stacked in the magazine bin 10a, it is beneficial to make the structure of the first loading device 200a more compact, thereby greatly reducing the space required.

[0071] Further, the magazine bin 10a is also provided with a photoelectric sensor 11a, which is used to detect whether there is a magazine A in the magazine bin 10a. If the photoelectric sensor 11a detects that there is no magazine A in the magazine bin 10a, an alarm or the like can be used to remind the operator to timely load the magazine A full of sheets into the magazine bin 10a.

[0072] In some embodiments, the first loading device 200a further comprises a supporting mechanism 50a arranged between the magazine bin 10a and the taking station C, which is used to support the magazine A moving between the magazine bin 10a and the taking station C. After the grabbing part 31a grabs the magazine A in the magazine bin 10a, it moves in the second direction X2, thereby driving the magazine A in the magazine bin 10a to the supporting mechanism 50a, and moving on the supporting mechanism 50a to the taking station C, until reaching the taking station C. When the magazine A at the taking station C becomes an empty magazine, the grabbing part 31a moves in the second direction X2 to the magazine bin 10a, thereby driving the empty magazine to move on the supporting mechanism 50a to the magazine bin 10a, until the empty magazine enters the magazine bin 10a. Thus, the supporting mechanism 50a is used to support the magazine A transferred between the magazine bin 10a and the taking station C, so as to avoid the magazine A from turning over or even falling off.

[0073] Specifically, the supporting mechanism 50a comprises a supporting frame 51a and a plurality of guide wheels 52a mounted on the supporting frame 51a. The supporting frame 51a has a transfer channel (not labeled in the figure) extending longitudinally in the second direction X2. The transfer channel is provided with a plurality of guide wheels 52a on both sides. The plurality of guide wheels 52a are used to limit the passing magazine A in the transfer channel, i.e. each guide wheel 52a guides the passing magazine A, so that the magazine A moves in the second direction X2 in the transfer channel. Thus, under the guidance of each guide wheel 52a, the magazine A can accurately enter and exit the magazine bin 10a and the taking station C, so as to ensure that the magazine A can be accurately transferred between the magazine bin 10a and the taking station C.

[0074] Further, the support frame 51a has two support strips 53a arranged side by side and each extending longitudinally along the second direction X2 between the magazine 10a and the taking station C. The two support strips 53a form the transfer channel described above for jointly supporting the passing magazine A. Each guide wheel 52a is arranged in two rows, and each guide wheel 52a in each row is arranged spaced apart along the second direction X2. The two rows of guide wheels 52a are respectively located outside the two support strips 53a, so that the two rows of guide wheels 52a limit the passing magazine A in the transfer channel, avoiding the moving track of the magazine A from deviating and causing the magazine A to fail to accurately enter the magazine 10a or the taking station C.

[0075] In specific embodiments, the pushing mechanism includes a pushing moving seat (not shown in the figure) and a pushing driving member 32a. The pushing moving seat is movably connected to the support frame 51a along the second direction X2. The pushing driving member 32a is installed on the support frame 51a, and the driving end of the pushing driving member 32a is connected to the pushing moving seat, so that the pushing driving member 32a can drive the pushing moving seat to move relative to the support frame 51a along the second direction X2. The grabbing part 31a is installed on the pushing moving seat, so that the grabbing part 31a can move along the second direction X2 together with the pushing moving seat, thereby enabling the grabbing part 31a to drive the magazine A to transfer between the magazine 10a and the taking station C.

[0076] Optionally, the pushing moving seat is installed on the support frame 51a through guide components such as guide rails or guide rods, so as to guide the movement of the pushing moving seat relative to the support frame 51a through the guide components such as guide rails or guide rods, so that the movement precision of the pushing moving seat along the second direction X2 meets the design requirements.

[0077] Optionally, the grabbing part 31a includes a first clamping jaw cylinder 311a and a first clamping jaw 313a. The first clamping jaw cylinder 311a is installed on the pushing moving seat, and the first clamping jaw 313a is installed on the driving end of the first clamping jaw cylinder 311a. Each magazine A has a clamping matching part 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 part A1 on the magazine A. Of course, in other embodiments, the grabbing part 31a can also adopt other grabbing structures as long as it can clamp or release the clamping matching part A1 on the magazine A, which is not limited herein.

[0078] In the embodiment of the present application, the first feeding device 200a further comprises a positioning mechanism 60a arranged at the material taking station C. The positioning mechanism 60a can be controlled to be positioned with or separated from the material box A arriving at the material taking station C. In this way, when the grabbing part 31a grabs the material box A at the material bin 10a and drives the material box A to the material taking station C, the positioning mechanism 60a is controlled to be positioned with the material box A, so as to position and fix the material box A at the material taking station C, which on one hand ensures that the position accuracy of the material box A meets the design requirements, and on the other hand avoids the position deviation of the material box A in the process of taking the material sheet by the material sheet robot 300.

[0079] Specifically, in the embodiment, the positioning mechanism 60a comprises a positioning driving part 61a and a positioning pin 62a connected to the driving end of the positioning driving part 61a. Each material box A is provided with a positioning hole capable of being positioned with the positioning pin 62a. When the grabbing part 31a drives the material box A to move from the material bin 10a to the material taking station C, the positioning driving part 61a drives the positioning pin 62a to extend towards 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 taking station C. After all the material sheets in the material box A at the material taking station C are taken away, the positioning driving part 61a drives the positioning pin 62a to retract, so that the positioning pin 62a exits from the positioning hole on the empty material box A, so that the empty material box A at the material taking station C can be driven by the grabbing part 31a to return to the material bin 10a.

[0080] Further, the number of the positioning mechanism 60a is two, and the two positioning mechanisms 60a are respectively located at the opposite sides of the material box A arriving at the material taking station C, so that the two positioning mechanisms 60a respectively position the material box A from the two sides of the material box A, which ensures that the positioning of the material box A is more accurate and further improves the position accuracy of the material box A.

[0081] In the embodiment of the present application, the first feeding device 200a further comprises a jacking mechanism 40a, which comprises a jacking driving part 41a and a jacking part 42a connected to the driving end of the jacking driving part 41a. The jacking part 42a is located below the material box A arriving at the material taking station C. The jacking driving part 41a is used to drive the jacking part 42a to move upwards, so as to jack the material sheets in the material box A arriving at the material taking station C, so as to facilitate the material sheet robot 300 to accurately suck the uppermost material sheet in the material box A.

[0082] Further, the jacking member 42a is movably connected to the support frame 51a in a lifting manner, the jacking drive 41a is installed on the support frame 51a, and the driving end of the jacking drive 41a is connected to the jacking member 42a, so that the jacking drive 41a can drive the jacking member 42a to ascend or descend relative to the support frame 51a. Alternatively, the jacking drive 41a can be an electric cylinder. Of course, in other embodiments, the jacking drive 41a can also be other types of linear drive modules as long as it can drive the jacking member 42a to ascend or descend, which is not limited here.

[0083] Alternatively, the jacking member 42a is installed on the support frame 51a through guide members such as guide rails or guide rods, so that the movement of the jacking member 42a relative to the support frame 51a is guided by the guide members such as guide rails or guide rods, which is beneficial to improve the movement precision of the jacking member 42a when ascending or descending.

[0084] It should be noted that, in actual use, after the grabbing part 31a drives the magazine A to reach the material taking station C, the magazine A is positioned by the positioning mechanism 60a. Then, the laminating mechanical arm 300 moves to the upper side of the magazine A located at the material taking station C and gradually descends until the laminating mechanical arm 300 sucks the uppermost laminates in the magazine A located at the material taking station C. Then, the laminating mechanical arm 300 ascends, thereby driving the sucked laminates to ascend. Since the adjacent two layers of laminates in the magazine A are attached to each other, there is a certain binding force between them. When the laminating mechanical arm 300 sucks the uppermost laminates and ascends, the uppermost laminates will also ascend with the next layer of laminates, thereby causing the laminating mechanical arm 300 to take away two or more laminates at a time.

[0085] In order to ensure that the laminating mechanical arm 300 takes away only one laminate at a time, in the embodiment of the present application, the first feeding device 200a further comprises a double sheet preventing mechanism (not marked in the figure). The double sheet preventing mechanism comprises a mounting frame 71a and a double sheet preventing member 72a installed on the mounting frame 71a. The double sheet preventing member 72 is located above the magazine A reaching the material taking station C. The double sheet preventing member 72a comprises a blowing member and / or a brush. In this way, during the process that the laminating mechanical arm 300 sucks the laminates and moves upward, the blowing member blows on the laminates sucked by the laminating mechanical arm 300 and / or the brush scrapes the laminates sucked by the laminating mechanical arm 300, so that the uppermost laminates are separated from the next layer of laminates, thereby ensuring that the laminating mechanical arm 300 can only take away one laminate at a time (i.e., can only take away the uppermost laminates in the magazine A).

[0086] In specific embodiments, the position of the mounting frame 71a in the vertical direction is adjustable, thereby adjusting the height of the double sheet preventing member 72a and ensuring that the double sheet preventing effect of the double sheet preventing member 72a is better.

[0087] Further, the mounting rack 71a is movably connected to the support rack 51a in a lifting manner. The anti-double mechanism further comprises an adjusting drive 73a mounted on the support rack 51a, and a driving end of the adjusting drive 73a is connected to the mounting rack 71a, so that the adjusting drive 73a can drive the mounting rack 71a to move along the vertical direction (i.e. to rise or fall) relative to the support rack 51a, that is, to adjust the position of the mounting rack 71a in the vertical direction, so as to adjust the height of the anti-double piece 72a.

[0088] Optionally, the adjusting drive 73a can be an electric cylinder. Of course, in other embodiments, the adjusting drive 73a can also be other types of linear drive modules, as long as it can drive the mounting rack 71a to move along the vertical direction to adjust the position, which is not limited here.

[0089] Optionally, the mounting rack 71a can be mounted on the support rack 51a through guide rails or guide columns and the like guiding components, so as to guide the movement of the mounting rack 71a along the vertical direction relative to the support rack 51a through the guide rails or guide columns and the like guiding components, so that the movement precision of the mounting rack 71a meets the design needs.

[0090] Specifically, the support rack 51a has a defective position D for placing the waste collecting box B. When the laminated sheet taken by the laminated sheet manipulator 300 is a defective laminated sheet, the laminated sheet manipulator 300 transfers the defective laminated sheet to the waste collecting box B located at the defective position D. Optionally, the defective position D is located on the side of the material taking station C away from the material bin 10.

[0091] Please refer to FIG. 4, in the embodiment of the present application, the second feeding device 200b comprises a unwinding assembly 10b, a cutting assembly 20b, a suction assembly 30b and a pulling assembly 40b. The unwinding assembly 10b is used for unwinding and outputting the material belt E to the downstream. The cutting assembly 20b is arranged downstream of the unwinding assembly 10b, and is used for cutting the material belt E passing through. The suction assembly 30b is arranged downstream of the cutting assembly 20b, and comprises a suction platform 31b used for suctioning the material belt E passing through. The pulling assembly 40b is used for clamping the material belt E at the cutting assembly 20b, and pulling the clamped material belt E to the suction platform 31b.

[0092] The second feeding device 200b in the actual use process, the unwinding assembly 10b to the cutting assembly 20b unwinding output material belt E. First, the material pulling assembly 40b moves to the cutting assembly 20b, and clamps the starting end of the material belt E. Then, the material pulling assembly 40b moves to the adsorption platform 31b until a certain length of the material belt E is located on the adsorption platform 31b. Then, the material pulling assembly 40b releases the starting end of the material belt E, and the adsorption platform 31b adsorbs and fixes the material belt E thereon. Then, the cutting assembly 20b cuts the passing material belt E, and the part of the material belt E adsorbed and fixed by the adsorption platform 31b is cut off, which is a material sheet. Then, the adsorption platform 31b stops adsorbing the material sheet, and the corresponding sheet stacking manipulator 300 sucks the material sheet on the adsorption platform 31b. Then, the sheet stacking manipulator 300 stacks the sucked material sheet on the sheet stacking table 100.

[0093] Thus, the second feeding device 200b in the present application pulls out a certain length of the material belt E to the adsorption platform 31b by the material pulling assembly 40b each time, and cuts it by the cutting assembly 20b, so as to form a material sheet with a required length on the adsorption platform 31b for the sheet stacking manipulator 300 to take away and stack. Compared with the prior art, the present application directly cuts the material belt E to form a material sheet, and the material sheet is adsorbed and fixed by the adsorption platform 31b, so that the material sheet remains flat, ensuring that the sheet stacking manipulator 300 can easily take the sheet, greatly improving the sheet stacking efficiency.

[0094] Specifically, the second feeding device 200b further comprises a mounting seat 80b and a deviation correcting driving member 90b. The unwinding assembly 10b is arranged on the mounting seat 80b, so that the unwinding assembly 10b and the material belt E unwound and output by the unwinding assembly 10b can move together with the mounting seat 80b. The mounting seat 80b is connected with the driving end of the deviation correcting driving member 90b, so that the deviation correcting driving member 90b can drive the mounting seat 80b to move, thereby driving the unwinding assembly 10b and the material belt E unwound and output by the unwinding assembly 10b to correct the deviation, and further facilitating to improve the position accuracy of the material sheet formed on the adsorption platform 31b subsequently, and ensuring that the sheet stacking manipulator 300 can accurately take the sheet.

[0095] Further, the moving direction of the mounting seat 80b is parallel to the width direction of the material belt E unwound and output by the unwinding assembly 10b, that is, the deviation correcting driving member 90b can drive the mounting seat 80b to move along the width direction of the material belt E, thereby driving the material belt E to adjust the position along the width direction thereof (i.e. correct the deviation), and facilitating to improve the position accuracy of the material sheet formed on the adsorption platform 31b subsequently. It should be noted that the deviation correcting driving member 90b can be a linear motor, and of course can also be other types of linear driving modules, as long as it can drive the mounting seat 80b to move along the width direction of the material belt E, which is not limited herein.

[0096] Further, the second feeding device 200b further comprises a guide rail 81b extending along the width direction of the material belt E. The mounting base 80b is provided with a sliding block 82b, which is arranged on the guide rail 81b and is movable along the guide rail 81b. In this way, the movement of the mounting base 80b is guided by the movement of the sliding block 82b along the guide rail 81b, so that the deviation correction movement of the material belt E is more accurate and reliable.

[0097] In specific embodiments, the second feeding device 200b further comprises a deviation correction sensor 50b arranged between the cutting assembly 20b and the unwinding assembly 10b. The deviation correction sensor 50b is used to detect the position of the passing material belt E in the width direction thereof. The deviation correction sensor 50b is in communication connection with the deviation correction driving member 90b, so that the deviation correction driving member 90b can drive the mounting base 80b to move according to the detection result of the deviation correction sensor 50b, thereby driving the material belt E to correct the deviation. In this way, when the deviation correction sensor 50b detects that the position of the material belt E in the width direction thereof has deviation, the deviation correction driving member 90b controls the mounting base 80b to move along the width direction of the material belt E, thereby driving the material belt E to adjust the position (i.e., correct the deviation) in the width direction thereof.

[0098] In embodiments of the present application, the unwinding assembly 10b comprises an unwinding mechanism 11b and a buffer mechanism 12b, both of which are mounted on the mounting base 80b. The unwinding mechanism 11b is used to unwind and output the material belt E to the downstream. The buffer mechanism 12b is arranged downstream of the unwinding mechanism 11b and is used to pass the material belt E and buffer the material belt E. In this way, the material belt E is buffered by the buffer mechanism 12b, so that when the pulling assembly 40b pulls the material belt E to the downstream, the material belt E consumed is the material belt E buffered by the buffer mechanism 12b, thereby avoiding directly pulling the material belt E on the unwinding mechanism 11b, and further reducing the risk of pulling off the material belt E.

[0099] Further, the unwinding assembly 10b further comprises 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 mounting base 80b and are respectively located on both sides of the passing material belt E, thereby respectively removing dust from the surfaces of both sides of the material belt E to avoid the subsequent formation of dust on the surface of the material sheet.

[0100] Further, the unwinding assembly 10b further comprises an electrostatic removal mechanism arranged between the unwinding mechanism 11b and the buffer mechanism 12b. The electrostatic removal mechanism is arranged on the mounting base 80b and is used to eliminate static electricity on the passing material belt E. Alternatively, the electrostatic removal mechanism can be arranged on the first dust removal mechanism 13b and / or the second dust removal mechanism 14b.

[0101] In some embodiments, the cutting assembly 20b comprises an upper cutter 21b, a lower cutter 22b and a cutting driving member 23b. The upper cutter 21b is arranged opposite to the lower cutter 22b, and a cutting passage is formed between the upper cutter 21b and the lower cutter 22b for the tape E to pass through. The upper cutter 21b is mounted on a driving end of the cutting driving member 23b, so that the cutting driving member 23b can drive the upper cutter 21b to move close to or away from the lower cutter 22b to cut the tape E passing through the cutting passage. Thus, when the tape E needs to be cut, first, the cutting driving member 23b drives the upper cutter 21b to gradually move close to the lower cutter 22b until the tape E passing through is cut off. Then, the cutting driving member 23b drives the upper cutter 21b to move away from the lower cutter 22b until it returns to the initial position. Optionally, the cutting driving member 23b can be a pneumatic cylinder.

[0102] In some embodiments, the second feeding device 200b further comprises a 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 pressing assembly 60b comprises a pressing plate 61b, a backing plate 62b and a pressing driving member 63b. The pressing plate 61b is arranged opposite to the backing plate 62b, and a pressing passage is formed between the pressing plate 61b and the backing plate 62b for the tape E to pass through. The driving end of the pressing driving member 63b is connected with the pressing plate 61b, so that the pressing driving member 63b can drive the pressing plate 61b to move close to or away from the backing plate 62b. Thus, before the pulling assembly 40b clamps the starting end of the tape E at the cutting assembly 20b and pulls the tape E towards the adsorption platform 31b, the pressing driving member 63b drives the pressing plate 61b to move away from the backing plate 62b, so that the pressing plate 61b and the backing plate 62b loosen the tape E. Before the cutting assembly 20b cuts the tape E, the pressing driving member 63b drives the pressing plate 61b to move close to the backing plate 62b until the tape E is tightly fixed on the backing plate 62b. That is, before cutting, the tape E upstream of the cutting position is tightly fixed on the backing plate 62b by the pressing plate 61b, and the tape E downstream of the cutting position is adsorbed and fixed by the adsorption platform 31b, thereby facilitating the improvement of cutting quality. Optionally, the pressing driving member 63b can be a pneumatic cylinder.

[0103] In some embodiments, the second feeding device 200b further comprises a dust removal assembly 70b arranged at the cutting assembly 20b. The dust removal assembly 70b is used to suck the dust generated by cutting the tape E by the cutting assembly 20b, thereby avoiding the presence of dust on the subsequent formed pieces.

[0104] Further, the dust suction port of the dust removal assembly 70b is arranged at the lower cutter 22b, so that the dust removal assembly 70b can easily suck the dust generated by cutting the tape E.

[0105] In some embodiments, the adsorption assembly 30b further comprises a lifting drive 32b. The adsorption platform 31b is mounted on the driving end of the lifting drive 32b, which is used to drive the adsorption platform 31b to move up or down. Thus, when there is no piece on the adsorption platform 31b, the lifting drive 32b drives the adsorption platform 31b to move down, on the one hand, so that the height of the adsorption platform 31b is convenient for the pulling assembly 40b to move for pulling, and on the other hand, so that the height positions of the adsorption platform 31b, the backing plate 62b and the lower cutter 22b are substantially consistent, which is conducive to improving the cutting quality and the position accuracy of the piece. When there is a piece on the adsorption platform 31b, the lifting drive 32b drives the adsorption platform 31b to move up, so as to facilitate the piece taking mechanical hand 300 to take the piece on the adsorption platform 31b, which is conducive to further reducing the difficulty of the piece taking mechanical hand 300. Optionally, the lifting drive 32b can be a pneumatic cylinder.

[0106] In some embodiments, the pulling assembly 40b comprises a moving seat 41b, a moving drive 42b and a clamping mechanism 43b. The moving seat 41b is connected with the driving end of the moving drive 42b, and the clamping mechanism 43b is mounted on the moving seat 41b and can be controlled to clamp or release the material strip E. The moving drive 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, thereby enabling the clamping mechanism 43b to clamp the starting end of the material strip E at the cutting assembly 20b and to pull the material strip E to the adsorption platform 31b. Thus, when a piece is needed on the adsorption platform 31b, first, the moving drive 42b drives the moving seat 41b to move towards 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 to clamp the starting end of the material strip E at the cutting assembly 20b; then, the moving drive 42b drives the moving seat 41b to move away from the cutting assembly 20b until the clamping mechanism 43b is moved to the side of the adsorption platform 31b away from the cutting assembly 20b, thereby pulling a certain length of the material strip E to the adsorption platform 31b; then, the pressing drive 63b drives the pressing plate 61b to press the material strip E on the backing plate 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 assembly 20b cut the material strip E passing through, and at this time, the material strip E on the adsorption platform 31b is a piece.

[0107] It should be noted that the moving drive 42b can be an electric cylinder, and of course can be other types of linear modules, as long as it can drive the moving seat 41b to move, which is not limited here.

[0108] Optionally, the clamping mechanism 43b comprises a second clamping jaw cylinder 431b and a second clamping jaw 433b, the second clamping jaw cylinder 431b is mounted on the moving seat 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 belt E.

[0109] The working process of the second material feeding device 200b will be described below in combination with FIG. 4.
