DETAILED DESCRIPTION

[0046] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] like Figures 1 to 11 A specific embodiment of the module processing device shown includes: a battery cell stacking device 100, a steel strip sleeve removal device 200, a steel strip discharge device 300 and a module extrusion and conveying device 400. The module extrusion and conveying device 400 and the steel strip sleeve removal device 200 are arranged downstream of the battery cell stacking device 100, and the module extrusion and conveying device 400 is located between the battery cell stacking device 100 and the steel strip sleeve removal device 200. The steel strip sleeve removal device 200 can switch between the steel strip removal position and the steel strip sleeve position, the steel strip discharge device 300 includes a feed port and a discharge port, and the discharge port is arranged corresponding to the steel strip removal position, and the module extrusion and conveying device 400 can extrude the battery cell module and convey the battery cell module to the steel strip sleeve position.

[0051] The battery cells are stacked by using the battery cell stacking device 100 to form a battery cell module. The stacked battery cell module is extruded and conveyed to the steel belt sheathing position by the module extrusion and conveying device 400, and the steel belt sheathing device 200 clamps the steel belt from the discharge port of the steel belt discharging device 300 and sheathes the steel belt on the extruded battery cell module. In the process of stacking, extruding and sheathing the steel belt of the battery cell module, by setting the steel belt discharging device 300, each steel belt is discharged at the same position, which makes it convenient for the steel belt sheathing device 200 to take the steel belt from the same position each time, and the steel belt is convenient to take.

[0052] like Figures 2 to 5As shown, the battery cell stacking device 100 includes a conveying mechanism 110, a pushing mechanism 120 and a stacking mechanism 130. The conveying mechanism 110 is used to continuously convey the battery cells. The pushing mechanism 120 is arranged corresponding to the output end of the conveying mechanism 110. The pushing mechanism 120 can push the battery cells located at the output end of the conveying mechanism 110 to a predetermined position. The stacking mechanism 130 is arranged downstream of the pushing mechanism 120. The stacking mechanism 130 includes a clamping portion 131, a guide portion 132 and a stacking portion 133. The clamping portion 131 is arranged opposite to the stacking portion 133. The guide portion 132 can connect the clamping portion 131 and the stacking portion 133. The clamping portion 131 can clamp the battery cells at a predetermined position and allow the battery cells to slide downward to the stacking portion 133 through the guide portion 132.

[0053] The pushing mechanism 120 is used to push the battery cells transported by the conveying mechanism 110 to a predetermined position. The stacking mechanism 130 can clamp the battery cells at the predetermined position and make the battery cells slide down to the stacking portion 133 through the guide portion 132, thereby realizing continuous transportation and stacking of the battery cells, simplifying the stacking process of the battery cells, and improving the stacking efficiency of the battery cells.

[0054] like Figures 2 to 4 As shown, the pushing mechanism 120 includes a bracket 121, a second transverse driving structure 122, a second vertical driving structure 123 and a cell pushing part 124. The bracket 121 is located at the output end of the conveying mechanism 110, the second transverse driving structure 122 is arranged on the bracket 121 and is located above the conveying mechanism 110, the second vertical driving structure 123 is drivingly connected with the driving end of the second transverse driving structure 122, and the cell pushing part 124 is connected to the driving end of the second vertical driving structure 123. The second transverse driving structure 122, the second vertical driving structure 123 and the cell pushing part 124 are supported above the output end of the conveying mechanism 110 by the bracket 121, the second vertical driving structure 123 can drive the cell pushing part 124 to move vertically close to or away from the conveying surface of the conveying mechanism 110, and the second transverse driving structure 122 can drive the second vertical driving structure 123 to reciprocate between the output end of the conveying mechanism 110 and a predetermined position.

[0055] The second vertical driving structure 123 is used to drive the battery cell pushing part 124 to move to the side of the battery cell on the conveying mechanism 110, and then the second vertical driving structure 123 is driven to move horizontally by the second horizontal driving structure 122 to push the battery cell to a predetermined position during the movement. The pushing mechanism 120 has a simple structure and is easy to use, thereby improving the pushing efficiency of the battery cell.

[0056] In this embodiment, the second transverse driving structure 122 and the second vertical driving structure 123 are both cylinders.

[0057] like Figures 2 to 4As shown, the pushing mechanism 120 is located on the side of the conveying mechanism 110, and the pushing mechanism 120 includes a connecting structure 125, which is arranged on the bracket 121, and the connecting structure 125 is perpendicular to the conveying direction of the conveying mechanism 110. One end of the connecting structure 125 is connected to the conveying mechanism 110, and the other end of the connecting structure 125 is connected to the clamping part 131, and the clamping position of the clamping part 131 forms a predetermined position. In the process of the second horizontal driving structure 122, the second vertical driving structure 123 and the battery cell pushing part 124 cooperating to push the battery cell, the battery cell moves to the clamping part 131 via the connecting structure 125, that is, the battery cell is continuously pushed from the conveying mechanism 110 to the clamping part 131, and the clamping part 131 can clamp or support the battery cell, and then the clamping part 131 can release the battery cell, so that the battery cell slides to the stacking part 133 via the guide part 132.

[0058] Of course, the clamping portion 131 can also be set as a retractable clamping structure. When the battery cell is pushed to the output end of the connecting structure 125, the clamping portion 131 extends to the output end of the connecting structure 125 to clamp the battery cell, then retracts to reset and releases the battery cell for stacking. At this time, the above-mentioned predetermined position is the output end position of the connecting structure 125.

[0059] It is worth mentioning that the clamping portion 131 can clamp the battery cell to adjust the position of the battery cell to achieve calibration and positioning of the battery cell, so that the battery cell can accurately slide down in cooperation with the guide portion 132 to achieve precise stacking of each battery cell and ensure the stacking accuracy of the battery cell.

[0060] The connection structure 125 can be used to support and guide the battery cell during its movement, thereby ensuring the stability and position accuracy of the battery cell during its movement.

[0061] Of course, the pushing mechanism 120 may also be other structures that can realize the transfer of the battery cells between the conveying mechanism 110 and the stacking mechanism 130, such as an air gripper grasping and transporting mechanism.

[0062] Of course, according to the overall layout of the equipment, the stacking mechanism 130 can also be arranged directly in front of the conveying mechanism 110, that is, the clamping part 131 is arranged on the conveying path of the conveying mechanism 110, and the driving direction of the second transverse driving structure 122 and the extension direction of the connecting structure 125 are both arranged in the same direction as the conveying direction of the conveying mechanism 110, that is, the pushing mechanism 120 can push the battery cell to the stacking mechanism 130 along the conveying direction of the conveying mechanism 110.

[0063] It is worth noting that when the clamping portion 131 is located directly in front of the conveying mechanism 110 and is arranged close to the output end of the conveying mechanism 110 , it is not necessary to provide the pushing mechanism 120 , and the conveying mechanism 110 can directly convey the battery cells to the clamping portion 131 .

[0064] In this embodiment, if Figures 2 to 4 As shown, the conveying mechanism 110 includes two conveying paths arranged side by side in the horizontal direction. Correspondingly, two second horizontal driving structures 122, two second vertical driving structures 123 and two battery cell pushing parts 124 are also respectively provided to push the two battery cells arranged side by side at the output end of the conveying mechanism 110 respectively.

[0065] It is worth mentioning that please refer to Figure 4 The two second lateral driving structures 122 are relatively spaced and arranged in parallel, and the two second vertical driving structures 123 are respectively arranged on the two second lateral driving structures 122 and are staggered in the lateral direction, so that the two battery cell pushing parts 124 respectively correspond to the two battery cells arranged side by side, and the battery cell pushing part 124 can push the battery cell on the side of the battery cell away from the stacking mechanism 130.

[0066] It should be further explained that, when a battery cell pushing part 124 close to the stacking mechanism 130 pushes the corresponding battery cell onto the clamping part 131, the second vertical driving structure 123 corresponding to the battery cell pushing part 124 drives the battery cell pushing part 124 to move upward, and returns horizontally under the drive of the corresponding second horizontal driving structure 122. At this time, the other battery cell pushing part 124 continues to push another battery cell (the battery cell away from the stacking mechanism 130 among the two battery cells arranged side by side) toward the stacking mechanism 130, and after pushing the battery cell onto the clamping part 131, the second vertical driving structure 123 drives the battery cell pushing part 124 to move upward, and the second horizontal driving structure 122 drives the second vertical driving structure 123 to return horizontally.

[0067] Of course, the conveying mechanism 110 can also be arranged with other numbers of conveying paths side by side, for example, three, by simply setting the second horizontal driving structure 122, the second vertical driving structure 123 and the battery cell pushing unit 124 corresponding to the conveying paths, and ensuring that there is no interference between the several second vertical driving structures 123 and the several battery cell pushing units 124 during the lateral reciprocating movement.

[0068] In this embodiment, the conveying mechanism 110 is a conveying belt line.

[0069] In this embodiment, if Figure 4 As shown, the connection structure 125 includes two guide grooves extending in the transverse direction, the two guide grooves are arranged at intervals, and the battery cell can pass between the two guide grooves.

[0070] It is worth mentioning that please refer to Figure 3 and Figure 4The two guide grooves are a longer guide groove and a shorter guide groove, the longer guide groove extends from the side of the conveying mechanism 110 away from the stacking mechanism 130 to the clamping portion 131 of the stacking mechanism 130, and the shorter guide groove extends from the side of the conveying mechanism 110 close to the stacking mechanism 130 to the clamping portion 131 of the stacking mechanism 130, and the longer guide groove is located downstream of the shorter guide groove along the conveying direction of the conveying mechanism 110. Therefore, the two battery cells arranged side by side in the transverse direction can be guided.

[0071] like Figure 5 As shown, the stacking mechanism 130 further includes a base plate 134 , and the clamping portion 131 , the guiding portion 132 and the stacking portion 133 are all disposed on the base plate 134 .

[0072] It is worth mentioning that please refer to Figure 5 The substrate 134 is a long strip plate, the guide portion 132 is fixedly arranged on the substrate 134, and the guide portion 132 is extended along the length direction of the long strip plate; the clamping portion 131 is fixedly arranged at the upper end of the substrate 134, and the stacking portion 133 and the clamping portion 131 are arranged opposite to each other in the length direction of the long strip plate.

[0073] like Figure 5 As shown, the stacking mechanism 130 also includes a stacking drive structure 135, which is arranged on the substrate 134 and is in transmission connection with the stacking portion 133 to drive the stacking portion 133 to approach or move away from the clamping portion 131. The stacking portion 133 is movably arranged so that the stacking portion 133 can be located close to the clamping portion 131 during stacking, and then gradually descends as the number of stacked cells increases, thereby ensuring the stability of the cell stacking process and reducing the impact force between the cells.

[0074] In this embodiment, if Figure 5 As shown, the stacking drive structure 135 includes a first motor 1351 and a first screw rod 1352 . The first motor 1351 can drive the first screw rod 1352 to rotate. The first screw rod 1352 is threadedly connected to the stacking portion 133 . The first screw rod 1352 is extended along the length direction of the base plate 134 .

[0075] In this embodiment, if Figure 5 As shown, a guide rail 1341 is further provided on the base plate 134 , and the stacking portion 133 is slidably connected to the guide rail 1341 . The guide rail 1341 is extended along the length direction of the base plate 134 , thereby improving the stability of the stacking portion 133 during movement.

[0076] In this embodiment, if Figure 5As shown, the substrate 134 is tilted relative to the vertical direction so that the battery cells can slide along the guide groove more smoothly, reducing the impact force between the battery cells during the battery cell stacking process, and facilitating the mutual alignment of the battery cells to ensure the stacking accuracy of the battery cells.

[0077] Of course, the substrate 134 may also be arranged in a vertical direction.

[0078] In this embodiment, if Figure 5 As shown, the guide portion 132 includes four guide slots 1321, and the four guide slots 1321 are arranged at intervals along the circumference of the stacking portion 133. Specifically, as shown in FIG. Figure 5 As shown, the four guide slots 1321 are located on the outer periphery of the stacking portion 133 and are disposed at the four corners of the stacking portion 133 , so that the battery cell can be guided at the four corners of the battery cell.

[0079] Of course, the guide slots 1321 may also be set to other numbers, such as two, three, etc.

[0080] like Figure 1 As shown, the module processing device also includes a module transfer device 500, which is arranged between the battery cell stacking device 100 and the module extrusion and conveying device 400, and the module transfer device 500 is suitable for transferring the battery cell module at the stacking part 133 of the stacking mechanism 130 to the module extrusion and conveying device 400.

[0081] Of course, the module extrusion and conveying device 400 can directly take out the battery cell module from the stacking mechanism 130 and extrude it, and then directly convey the battery cell module in the extruded state to the steel belt covering position, that is, the module extrusion and conveying device 400 also has the function of the module transfer device 500. For example, the module extrusion and conveying device 400 is set as a robot gripper.

[0082] like Figure 5 As shown, the battery cell stacking device 100 further includes a rotating mechanism 140, on which the stacking mechanism 130 is disposed, and the rotating mechanism 140 can drive the stacking mechanism 130 to rotate around a vertical direction. After the battery cell stacking is completed, the stacking mechanism 130 is rotated to correspond to the module transfer device 500, thereby improving the continuity between stacking and unloading.

[0083] In this embodiment, if Figure 5 As shown, two stacking mechanisms 130 are arranged at intervals along the rotational driving direction of the rotating mechanism 140, and the angle between the two stacking mechanisms 130 in the rotational driving direction is 180°. When one stacking mechanism 130 completes stacking and rotates to the unloading position, the other stacking mechanism 130 can be synchronously rotated to the stacking position, thereby realizing continuous stacking of the battery cells and further improving the stacking efficiency of the battery cells.

[0084] It is worth noting that the stacking mechanism 130 can also be set to other numbers to adapt to the transportation and stacking efficiency of the battery cells and the unloading and transportation efficiency of the battery cell modules.

[0085] Specifically, in this embodiment, the rotating mechanism 140 includes a rotating frame and a rotating driving unit 231 . The rotating driving unit 231 is suitable for driving the rotating frame to rotate around a vertical direction. The base plate 134 is connected to the rotating frame.

[0086] like Figure 1 and Figure 2 As shown, the cell stacking device 100 further includes a blocking mechanism 150, which is disposed above the conveying mechanism 110, and is disposed close to the pushing mechanism 120, and is located upstream of the pushing mechanism 120 along the conveying direction of the conveying mechanism 110, and the blocking mechanism 150 can be disposed on the conveying path of the cell. When the pushing mechanism 120 pushes the cell, the blocking mechanism 150 is disposed between the cell at the output end (the pushed cell) and the cell adjacent to it in the conveying direction, so as to prevent the subsequent cell from being transported forward and interfering with the pushing process and affecting the accuracy of the pushing.

[0087] It is worth noting that the blocking mechanism 150 can be mounted above the conveying mechanism 110 through a separate mounting frame, or can be directly mounted on the bracket 121 of the pushing mechanism 120 .

[0088] When using the cell stacking device 100 of the present embodiment to stack cell modules, first, the cell is conveyed to the output end of the conveying mechanism 110 by the conveying mechanism 110, and the blocking mechanism 150 blocks subsequent incoming materials; then, the second vertical driving structure 123 drives the cell pushing portion 124 to move downward to the side of the cell, and then the second horizontal driving structure 122 is used to drive the second vertical driving structure 123 to move horizontally close to the stacking mechanism 130, so as to push the cell to move to the clamping portion 131 via the connecting structure 125; finally, the clamping portion 131 releases the cell, and the cell slides down along the guide slot 1321 to the stacking portion 133, and in the process of cell stacking, the stacking portion 133 gradually moves from a position close to the clamping portion 131 toward a direction away from the clamping portion 131.

[0089] like Figures 6 to 9 As shown, the module extrusion and conveying device 400 includes a base 410, a pushing structure 420 and an extrusion structure 430. The pushing structure 420 is movably disposed on the base 410, and the extrusion structure 430 is disposed on the pushing structure 420. The extrusion structure 430 can clamp and extrude the battery cell module at both ends of the battery cell module, and the pushing structure 420 conveys the extrusion structure 430 together with the battery cell module to the steel belt covering position.

[0090] The cell module placed on the base 410 is clamped and squeezed by the squeezing structure 430, and the cell module in the squeezed state is transported to the steel belt sheathing position by the pushing structure 420, so that the steel belt sheathing device 200 can sheath the cell module with steel belt.

[0091] like Figure 6 As shown, the pushing structure 420 includes a pushing plate 421 and a pushing driving part 422. The pushing plate 421 is movably arranged on the base 410, and the pushing plate 421 is arranged vertically with the base 410. The pushing driving part 422 is arranged on the side of the pushing plate 421 away from the steel strip removing device 200, and the extrusion structure 430 is arranged on the side of the pushing plate 421 facing the steel strip removing device 200. The battery cell module to be covered with steel strip is loaded onto the base 410 by the loading mechanism, and the battery cell module is positioned by fitting the pushing plate 421, and then the extrusion structure 430 is used to squeeze the battery cell module, and then the battery cell module can be pushed from the base 410 to the steel strip covering position between a pair of first vertical driving structures 210 by the pushing driving part 422.

[0092] like Figure 6 As shown, the extrusion structure 430 includes a fixed plate 431, a movable plate 432 and an extrusion driving unit 433. The fixed plate 431 is vertically connected to the pushing plate 421, and the movable plate 432 is arranged opposite to the fixed plate 431. The extrusion driving unit 433 can drive the movable plate 432 to move closer to or away from the fixed plate 431.

[0093] The movable plate 432 is used to push and squeeze the battery cell module onto the fixed plate 431, so as to extrude and position the battery cell module in the length direction, thereby ensuring the position accuracy of the battery cell module when it is transported to the steel belt sleeve position.

[0094] In this embodiment, the pushing driving part 422 is a pneumatic cylinder, and the extruding driving part 433 is an electric cylinder.

[0095] In this embodiment, if Figure 6 As shown, a support roller 440 is provided between the base 410 and the pushing plate 421 , and the support roller 440 is utilized to support the pushing plate 421 during the movement of the pushing plate 421 , and the movement of the pushing plate 421 is more convenient.

[0096] like Fig.10 and Fig.11 As shown, the steel strip discharging device 300 includes a housing 310 and a pushing structure 320. A receiving cavity is provided in the housing 310, one end of the receiving cavity forms a feed port, and the other end of the receiving cavity forms a discharge port. The pushing structure 320 includes a movable steel strip pushing portion 321, which can extend into the receiving cavity and push the steel strip to move from the feed port toward the discharge port.

[0097] It is worth mentioning that please refer to Fig.10 The shell 310 is opened at both ends, and the accommodating cavity is connected to the outside through the openings at both ends.

[0098] It should be noted that the above-mentioned steel belt pushing part 321 can be movably arranged, including linear motion, rotational motion, etc., and it is only necessary to enable the steel belt pushing part 321 to drive the steel belt to move during the movement.

[0099] The outer contour of the steel strip is constrained by the shell 310 so as to arrange and cache the steel strip regularly. In addition, the pushing structure 320 is provided to push the steel strip so that the steel strip can be moved out from the discharge port in sequence, ensuring that each steel strip is discharged at the same position, making it convenient for the loading robot to take the material from the same position each time, and facilitating the loading of the steel strip.

[0100] like Fig.10 As shown, the housing 310 includes a bottom plate 312, an upper plate 313 and a side plate 314. The bottom plate 312 and the upper plate 313 are arranged at intervals relative to each other, and two side plates 314 are arranged at intervals relative to each other, and each side plate 314 connects the bottom plate 312 and the upper plate 313. The bottom plate 312, the upper plate 313 and the side plates 314 enclose a receiving cavity with openings at both ends.

[0101] like Fig.10 As shown, the inner surface of the upper plate 313 is provided with a magnetic attraction structure 340, and the magnetic attraction structure 340 is extended in the direction from the feed inlet to the discharge outlet. Therefore, in the process of the steel strip moving from the feed inlet to the discharge outlet, the magnetic attraction structure 340 can continuously adsorb and restrict the upper side of the steel strip to prevent the steel strip from tipping over.

[0102] In this embodiment, if Fig.10 As shown, the magnetic attraction structure 340 is a magnetic rubber strip, and a plurality of magnetic attraction structures 340 are arranged side by side at intervals to ensure the stability of the adsorption of the steel strip.

[0103] It is worth noting that the magnetic structure 340 is embedded in the inner surface of the upper plate 313 so that the magnetic structure 340 is flush with the inner surface of the upper plate 313. The steel belt can contact the magnetic structure 340 and the inner surface of the upper plate 313 during transportation, further ensuring the stability of the steel belt.

[0104] like Fig.10 As shown, the side plate 314 includes a pair of split plates 3141, the pair of split plates 3141 are arranged vertically at intervals, and a material pushing chute 311 is formed between the pair of split plates 3141. The steel belt pushing portion 321 can pass through the material pushing chute 311 and be inserted into the accommodating cavity. Fig.10As shown, the split plate 3141 located at the bottom is connected to the bottom plate 312, and the split plate 3141 located at the top is connected to the upper plate 313. The pushing structure 320 is arranged on the outer side of the side plate 314. The steel belt pushing part 321 is inserted into the accommodating cavity through the pushing chute 311, and pushes several steel belts forward from the rear side of the arranged steel belts.

[0105] It is worth noting that the rear side of the aforementioned plurality of steel strips is the side of the plurality of steel strips close to the feed port; and pushing the plurality of steel strips forward is to push the plurality of steel strips toward the discharge port.

[0106] In this embodiment, if Fig.11 As shown, the pushing structure 320 also includes a pushing drive part 322 and a mounting plate 323. The mounting plate 323 is located on the outside of the side plate 314 and is connected to the bottom plate 312 and the upper plate 313. The pushing drive part 322 is arranged on the mounting plate 323, and the pushing drive part 322 is transmission-connected to the steel belt pushing part 321.

[0107] It is worth mentioning that please refer to Fig.10 Two side plates 314 are extended outward from both sides of the bottom plate 312 and the upper plate 313 , the mounting plate 323 is connected to the sides of the bottom plate 312 and the upper plate 313 , and the push drive part 322 and the steel belt pushing part 321 are located on the inner side of the mounting plate 323 .

[0108] It should be noted that the pushing structure 320 can also be arranged corresponding to the side of the shell 310 where the feed port is arranged, that is, the pushing driving part 322 drives the steel belt pushing part 321 to enter the accommodating cavity from the feed port, and pushes the steel belts forward from the rear side of the steel belts. For example, the pushing driving part 322 is arranged as a driving cylinder, and the steel belt pushing part 321 is a pushing block or a pushing plate arranged on the driving end of the driving cylinder.

[0109] It is worth further explaining that the pushing structure 320 itself can be a driving cylinder (that is, there is no need to set up an additional pushing driving part 322), and the driving end of the driving cylinder (that is, the driving end of the driving cylinder serves as the steel belt pushing part 321) is used to directly push the steel belt to move.

[0110] In this embodiment, if Fig.11 As shown, the push drive unit 322 includes a second motor 3221 and a second screw rod 3222. The second motor 3221 is suitable for driving the second screw rod 3222 to rotate. The second screw rod 3222 extends from the feed port to the discharge port. The second screw rod 3222 is transmission-connected to the steel belt push unit 321. When the second motor 3221 drives the second screw rod 3222 to rotate, the steel belt push unit 321 moves along the second screw rod 3222 between the feed port and the discharge port.

[0111] In this embodiment, if Fig.11As shown, the steel belt pushing part 321 includes a mounting block 3211 and a pushing block 3212, the mounting block 3211 is arranged on the second screw rod 3222, the pushing block 3212 is arranged on the mounting block 3211, and an elastic member is arranged between the pushing block 3212 and the mounting block 3211, and the elastic force direction of the elastic member is perpendicular to the extension direction of the pushing chute 311, so that the pushing block 3212 can be inserted into or removed from the accommodating cavity through the pushing chute 311. In this embodiment, the elastic member is a spring.

[0112] By arranging an elastic member between the pusher block 3212 and the mounting block 3211, the pusher block 3212 can be inserted into the accommodating cavity when pushing the steel strip. When the steel strip in the housing 310 is insufficient, the pusher drive unit 322 drives the mounting block 3211 and the pusher block 3212 back to one end of the feed port, and the steel strip is replenished from the feed port. When replenishing the steel strip, the pusher block 3212 can be moved out of the accommodating cavity to facilitate the placement of the steel strip into the accommodating cavity. Moreover, after replenishing the steel strip, under the elastic force of the elastic member, the pusher block 3212 is reinserted into the accommodating cavity, and the pusher drive unit 322 drives the mounting block 3211 and the pusher block 3212 to push the replenished steel strip toward the discharge port, so that the replenished steel strip and the original remaining steel strip form a close-packed state.

[0113] In this embodiment, if Fig.11 As shown, a slide rail 3231 is provided on the mounting plate 323, and the slide rail 3231 is arranged parallel to the second screw rod 3222. The mounting block 3211 can be slidably arranged on the slide rail 3231 to guide and limit the movement of the mounting block 3211 and the pushing block 3212, so that the pushing process of the steel belt is more stable.

[0114] It is worth noting that the pusher driving part 322 can also be directly disposed on the housing 310 (the bottom plate 312 , the upper plate 313 or the side plate 314 ), and in this case, there is no need to additionally provide the mounting plate 323 .

[0115] like Fig.10 As shown, the steel strip discharging device 300 further includes a blocking structure 330, which is disposed on the housing 310 and near the discharging port. The blocking structure 330 has a blocking position disposed at the discharging port and a discharging position away from the discharging port. By providing the blocking structure 330, when the steel strip is replenished into the housing 310, the discharging port can be blocked to prevent the steel strip near the discharging port from escaping from the housing 310.

[0116] In this embodiment, if Fig.10As shown, the blocking structure 330 includes a cylinder and a blocking plate. The cylinder is disposed on the housing 310, and the blocking plate is disposed on the driving end of the cylinder. When the blocking structure 330 is in the blocking position, the cylinder extends to drive the blocking plate to block the discharge port; when the blocking structure 330 is in the discharge position, the cylinder retracts to drive the blocking plate away from the discharge port to fully expose the discharge port. Specifically, as Fig.10 As shown, there are a plurality of (two or more) blocking structures 330 , and the plurality of blocking structures 330 are disposed on the bottom plate 312 and the upper plate 313 .

[0117] Of course, the blocking structure 330 may also be other structures capable of blocking the discharge port. For example, the blocking structure 330 may be a rotatable structure, and when the blocking structure 330 is in the blocking position, the blocking structure 330 rotates to block the discharge port, and when the blocking structure 330 is in the discharge position, the blocking structure 330 rotates away from the discharge port.

[0118] like Fig.10 As shown, a relief notch 315 is provided on one side of the bottom plate 312 and the upper plate 313 close to the feed inlet, so as to facilitate the replenishment of steel strip into the shell 310 from the feed inlet.

[0119] like Figures 6 to 8 As shown, the steel strip sleeve removing device 200 includes a first vertical drive structure 210, a first transverse drive structure 220 and a material-retrieving structure 230. A pair of first vertical drive structures 210 are arranged at a relative interval, and the first transverse drive structure 220 is transmission-connected with the pair of first vertical drive structures 210, and the first transverse drive structure 220 can drive the pair of first vertical drive structures 210 to switch between the steel strip taking position and the steel strip sleeve position. The material-retrieving structure 230 is rotatably arranged on the first vertical drive structure 210, and at least one material-retrieving structure 230 is arranged on each first vertical drive structure 210. The material-retrieving structures 230 on a pair of first vertical drive structures 210 are arranged relative to each other, and the two material-retrieving structures 230 arranged relative to each other can clamp and sleeve the steel strip.

[0120] It is worth mentioning that please refer to Figure 7 The driving direction of the first horizontal driving structure 220 is the left-right direction in the figure, and the driving direction of the first vertical driving structure 210 is the up-down direction in the figure.

[0121] It should be noted that the first transverse driving structure 220 drives a pair of first vertical driving structures 210 and drives the picking structure 230 to move to the steel belt picking position, and the picking structure 230 rotates to a vertical state to clamp the steel belt. After the clamping is completed, the first transverse driving structure 220 drives a pair of first vertical driving structures 210 back to the steel belt sleeve position, and the picking structure 230 rotates to a horizontal state. The first vertical driving structure 210 drives the picking structure 230 to move vertically to sleeve the steel belt onto the battery cell module.

[0122] The first transverse driving structure 220 is used to make the material taking structure 230 take the material at the steel strip taking position, and then drive the steel strip back to the steel strip covering position, and the first vertical driving structure 210 is used to drive the steel strip to move in the vertical direction, so as to cover the steel strip on the battery cell module. Therefore, the automatic material taking and covering of the steel strip can be completed by a steel strip covering device 200, and the steel strip covering device 200 has a simple structure, and the steel strip taking and covering operations are simple.

[0123] In this embodiment, the first vertical driving structure 210 and the first horizontal driving structure 220 are both linear driving modules.

[0124] It is worth noting that, in the present embodiment, the driving mechanism includes a first vertical driving structure 210 and a first horizontal driving structure 220, that is, the driving mechanism can drive the material taking structure 230 to move in two directions to complete the steel strip taking and steel strip covering, respectively. In other alternative embodiments, the driving mechanism may only include a linear driving structure in one direction, and the steel strip taking position and the steel strip covering position are both located on the driving path of the linear driving structure, that is, the linear driving structure can drive the material taking structure 230 to move in one direction to complete the steel strip taking and steel strip covering. Moreover, when the material taking and covering can be achieved when the steel strip taking position and the steel strip covering position are at the same angular position of the material taking structure 230, it is not necessary to set the material taking structure 230 rotatably.

[0125] like Figure 6 As shown, the material picking structure 230 includes a rotary material pushing driving part 322 and a material picking clamping claw 232. The rotary material pushing driving part 322 is arranged on the first vertical driving structure 210, and the rotary material pushing driving part 322 can drive the material picking clamping claw 232 to rotate. Figure 6 As shown, the material taking clamping claw 232 includes two clamping ends arranged relatively spaced apart, and when clamping the steel strip, the steel strip is located between the two clamping ends. In the steel strip taking position, the two clamping ends are arranged in the vertical direction, and in the steel strip putting position, the rotary push driving part 322 drives the two clamping ends to rotate to be arranged in the horizontal direction.

[0126] In this embodiment, the rotary push driving part 322 is a rotary cylinder.

[0127] In this embodiment, a magnetic suction component is provided on the inner side of the material picking clamp 232, which can adsorb and fix the steel belt when the material picking clamp 232 picks up materials. When the material picking clamp 232 picks up materials, while ensuring the material picking stability, it does not need to provide excessive clamping force on the steel belt to cause deformation of the steel belt.

[0128] In this embodiment, the magnetic attraction component is a magnet.

[0129] like Figure 6 and Figure 8 As shown, two material-retrieving structures 230 are arranged on each first vertical driving structure 210, and the two material-retrieving structures 230 are arranged at intervals in the vertical direction, and the first vertical driving structure 210 can drive the two material-retrieving structures 230 to move away or approach synchronously. Therefore, two pairs of material-retrieving structures 230 are arranged on a pair of first vertical driving structures 210, and the pair of material-retrieving structures 230 located at the top can fit a steel strip from top to bottom to the upper position of the battery cell module, and the pair of material-retrieving structures 230 located at the bottom can fit another steel strip from bottom to top to the lower position of the battery cell module.

[0130] like Figure 6 As shown, a connection portion 240 is connected between the lower ends of a pair of first vertical drive structures 210, and a first lateral drive structure 220 is provided, and one first lateral drive structure 220 is connected to one of the first vertical drive structures 210. Therefore, by providing a first lateral drive structure 220, a pair of first vertical drive structures 210 can be driven to move at the same time, the structure is simple, and the synchronous movement of the pair of first vertical drive structures 210 is ensured.

[0131] In this embodiment, the connecting portion 240 may be a connecting plate or a connecting rod.

[0132] In this embodiment, if Figure 6 As shown, two steel strip discharging devices 300 are arranged at vertical intervals, and the two steel strip discharging devices 300 correspond to two pairs of material picking structures 230 respectively. The driving mechanism can drive each pair of material picking structures 230 to clamp the steel strip at the corresponding steel strip taking position and to put the steel strip on the steel strip putting position.

[0133] By arranging two pairs of material taking structures 230 on a pair of first vertical driving structures 210 and arranging two steel belt discharging devices 300 in cooperation with the two pairs of material taking structures 230, two upper and lower steel belts can be simultaneously covered on a battery cell module, thereby improving the efficiency of covering the battery cell module with steel belts.

[0134] In this embodiment, if Figures 6 to 9 As shown, the steel strip discharging device 300 and the module extrusion and conveying device 400 are respectively arranged on both sides of the steel strip sleeve removal device 200. The steel strip sleeve removal device 200 takes the steel strip from the steel strip discharging device 300 and then moves to the steel strip sleeve position. The module extrusion and conveying device 400 extrude and convey the battery cell module to the steel strip sleeve position. The steel strip sleeve removal device 200 then sleeves the steel strip on the battery cell module. The two steel strip discharging devices 300 are located on the moving path of the first vertical driving structure 210, and the discharging direction of the steel strip discharging device 300 is arranged in the horizontal direction.

[0135] The discharging direction of the steel strip discharging device 300 is set to the horizontal direction, and the first transverse driving structure 220 and the first vertical driving structure 210 are used to cooperate in taking and wrapping the steel strip, so that the discharging method of the steel strip is stable.

[0136] It is worth noting that the horizontal direction mentioned above is Figure 7 The left and right direction in .

[0137] When the module extrusion conveying device 400, the steel strip discharging device 300 and the steel strip sleeve removing device 200 of the present embodiment are used to sleeve the steel strip on the battery cell module, first, the first horizontal driving structure 220 drives a pair of first vertical driving structures 210 to move toward the steel strip discharging device 300, and the upper and lower pairs of material picking jaws 232 of the material picking structure 230 are in a vertical state at the steel strip picking position; the second motor 3221 is started to drive the second screw rod 3222 to rotate, and during the rotation of the second screw rod 3222, the steel strip pushing part 321 moves along the second screw rod 3222 toward the discharge port, and the steel strip pushing part 321 pushes a plurality of steel strips toward the discharge port, so that the steel strips are moved from the discharge port to the material picking position. The first lateral drive structure 220 drives a pair of first vertical drive structures 210 to return to the steel belt cover position, and the rotating push drive unit 322 drives the material picking clamp 232 to rotate to a horizontal state; the battery cell module is loaded onto the base 410, and the extrusion push drive unit 322 drives the movable plate 432 to move toward the fixed plate 431, so that the fixed plate 431 and the movable plate 432 squeeze the battery cell module, and push the push drive unit 322 to drive the extrusion structure 430 to move together with the battery cell module to the steel belt cover position; the pair of material picking structures 230 located above move downward, and the pair of material picking structures 230 located below move upward, so that both steel belts are put on the battery cell module.

[0138] When using the module processing device of the present embodiment, first, the battery cell stacking device 100 is used to stack the battery cells to form a battery cell module, and then the module transfer device 500 transfers the battery cell module on the stacking part 133 of the stacking mechanism 130 to the base 410 of the module extrusion and conveying device 400, the module extrusion and conveying device 400 extrude the battery cell module, and conveys the battery cell module in the extruded state to the steel belt sleeve position, and finally, the steel belt sleeve device 200 takes the steel belt at the discharge port of the steel belt discharge device 300 (steel belt taking position), and then drives the steel belt to the steel belt sleeve position, and sleeves the steel belt on the battery cell module in the extruded state.

[0139] This embodiment also provides a specific implementation of lithium battery manufacturing equipment, including the above-mentioned module processing device. The module processing device is used to stack, extrude and sheath the battery cells, thereby realizing continuous transportation and stacking of the battery cells, simplifying the battery cell stacking process, and improving the battery cell stacking efficiency. In addition, during the extrusion and transportation of the battery cell module, the transfer and transportation distance of the battery cell module is short. By setting the steel strip discharging device 300, each steel strip is discharged at the same position, which makes it convenient for the steel strip sheathing device 200 to take the steel strip from the same position each time, and the steel strip is convenient to take.

[0140] According to the above description, this patent application has the following advantages:

[0141] 1. By setting up the steel strip discharging device, each steel strip is discharged at the same position, so that the steel strip taking device can take the steel strip from the same position every time, and the steel strip taking is convenient;

[0142] 2. The continuous stacking of cells is achieved during the continuous conveying process of the conveying mechanism, and the conveying mechanism does not need to be stopped;

[0143] 3. Use the pusher mechanism to transfer the battery cells from the conveyor mechanism to the stacking mechanism, which is fast and improves the stacking efficiency;

[0144] 4. The steel strip sheathing process of the cell module is completed by cooperating with the module extrusion and conveying device, the steel strip discharging device and the steel strip sheathing device. In addition, during the cell module extrusion and conveying process, the transfer and conveying distance of the cell module is short.

[0145] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
