Description

Technical Field

[0001] The invention relates to the field of electric core processing equipment. Background Art

[0002] At present, the existing battery cell processing equipment usually operates according to the following process: the battery cells are arranged on the line according to the formula, and the pallets flow into the OCV & code scanning inspection for inspection. After the inspection is completed (unqualified products are marked as NG materials), the materials are first transported to the gluing station via pallets, and the six-axis robot or four-axis robot glues the OK materials. After gluing, the pallets carry the materials into the gluing inspection station for inspection (unqualified glue products are also marked as NG materials), and then the OK materials and NG materials are replaced. Finally, the pallet flows out to the battery cell offline station, and the six-axis robot takes the materials and stacks them offline.

[0003] When faced with high-precision products, such existing processing production lines cannot meet the production requirements of higher efficiency due to the problem of the start and stop speed of the line body conveying when the battery cells are transported through tooling and logistics, and have the defect of insufficient production stability. In addition, the existing processing production lines occupy a large area and the equipment has a small working range.

[0004] Based on this, how to improve the existing battery cell processing equipment and processes to achieve the goal of improving production stability and reducing space occupancy has become a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0005] In view of the above problems, the present invention proposes a miniaturized production line for fully compatible battery cell components, which adopts magnetic drive transportation to complete automatic testing, gluing, NG replacement and battery cell offline. Through the miniaturized processing production line, a series of complete processing processes such as OCV & code scanning, gluing and NG automatic replacement stations are integrated.

[0006] The technical solution of the present invention is:

[0007] like Figure 1 , 2 As shown, the miniaturized production line includes a main machine 1, in which an on-line robot 3, an OCV detection mechanism 4, a magnetic drive conveying mechanism 5, a large-surface glue peeling mechanism 6, an automatic glue sticking mechanism 7, an NG replacement mechanism 8 and an off-line robot 9 are arranged;

[0008] like Figure 3 , 4 As shown, the magnetic drive conveying mechanism 5 is a magnetic suspension conveying chain, which includes a ring track 51 fixedly installed in the host 1 and a magnetic suspension slider 52 slidably installed on the ring track 51, and each magnetic suspension slider 52 is installed with a battery tool 53 for clamping the battery cell;

[0009] like Figure 3 , 4 As shown, the circular track 51 passes through the areas where the on-line robot 3, the OCV detection mechanism 4, the automatic glue sticking mechanism 7, the NG replacement mechanism 8 and the off-line robot 9 are located in sequence;

[0010] The on-line robot 3 is used to grab the battery cells transported by the battery cell on-line mechanism 2 and place them on a battery cell tooling 53; the OCV detection mechanism 4 is used to perform OCV detection on the passing battery cells; the large-surface glue tearing mechanism 6 is arranged next to the automatic glue sticking mechanism 7, and the stickers on the large-surface glue are torn off by the large-surface glue tearing mechanism 6; the automatic glue sticking mechanism 7 is used to grab the large-surface glue with the removed stickers and stick it on the large surface of the passing battery cells; the NG replacement mechanism 8 is used to replace the passing NG material with OK material; the offline robot 9 is used to take away the processed battery cells on the battery tooling 53.

[0011] The circular track 51 has two straight segments and two arc segments, the upper line robot 3 and the lower line robot 9 are located above one of the straight segments, and the OCV detection mechanism is located above one of the arc segments; the other straight segment of the circular track 51 passes through the area where the automatic glue sticking mechanism 7 and the NG replacement mechanism 8 are located, and the large surface glue tearing mechanism 6 is located next to the automatic glue sticking mechanism 7, and the total length of the area where the large surface glue tearing mechanism 6, the automatic glue sticking mechanism 7, and the NG replacement mechanism 8 are located is close to the overall length of the circular track 51.

[0012] like Figure 7 , 8 As shown, the battery tooling 53 includes a base 531, a fixed stopper 532, a floating stopper 533 and a back stopper 534. The base 531 is fixedly mounted on the top surface of the magnetic suspension slider 52. The fixed stopper 532 and the movable stopper 533 are respectively used to clamp two small surfaces of the battery cell, and the back stopper 534 is used to resist the large surface of the back side of the battery cell.

[0013] The base 531 is fixedly mounted with a first guide rail 5311 designed parallel to the large surface of the battery cell and a second guide rail 5312 designed parallel to the small surface of the battery cell. The bottom of the fixed stopper 532 is slidably connected to the first guide rail 5311, and the fixed stopper 532 is detachably mounted on the base 531. The bottom of the back stopper 534 is slidably connected to the second guide rail 5312, and the back stopper 534 is also detachably mounted on the base 531.

[0014] A third guide rail 5313 parallel to the first guide rail 5311 is fixedly mounted on the base 531, and the bottom of the floating stopper 533 is slidably connected to the third guide rail 5313;

[0015] A fixed block 535 fixedly mounted on the base 531 and a compression spring between the fixed block 535 and the floating block 533 are provided on the side of the floating block 533 facing away from the center of the base 531, so that the floating block 533 maintains a movement trend toward the center of the base 531;

[0016] A fourth guide rail 5314 is also provided between the first guide rail 5311 and the third guide rail 5313 and is perpendicular to the first guide rail 5311 and the third guide rail 5313. A stopper slide bar 536 is provided on the side of the floating stopper 533 facing the center of the base 531 and is slidably connected to the fourth guide rail 5314. An oblique guide groove 5361 is provided on the stopper slide bar 536. A guide column is inserted into the oblique guide groove 5361. The floating stopper 533 is fixedly connected to the guide column. Under the action of the compression spring, the floating stopper 533 pushes the guide column toward the center of the base 531 and forces the stopper slide bar 536 to translate.

[0017] like Figure 6 , 7 As shown in Figures 8 and 8, an electromagnetic unlocker 510 for unlocking the battery cell tooling 53 is also fixedly installed on the annular track 51. The electromagnetic unlocker 510 is located on the inner side of the movement trajectory of the stop slide 536 and is arranged outward. The center of the end of the stop slide 536 has a magnetic pole. When the electromagnetic unlocker 510 is energized, it generates the same magnetic pole as the end of the stop slide 536, so that the stop slide 536 overcomes the force of the compression spring and moves along the fourth guide rail 5314, thereby forcing the floating stop block 533 to move away from the center of the base 531 under the guidance of the oblique guide groove 5361.

[0018] like Figure 6 As shown, the electromagnetic unlocker 510 is provided in plurality, two of which are provided below the upper line robot 3 and the lower line robot 9 respectively, and at least one is provided in the area where the NG replacement mechanism 8 is located.

[0019] like Fig. 9 As shown, the miniaturized production line also includes a battery cell online mechanism 2, which includes an extrusion table 21, a blocking block 22, a transfer table 23 and a transfer robot 24 for transferring the battery cells on the extrusion table 21 to the transfer table 23.

[0020] The present invention takes into account that the gluing and stacking of the cell assembly is the first process to ensure the module automation line, and its functional stability and efficiency are directly related to the operation of the subsequent production process; therefore, it proposes the miniaturization of the cell assembly equipment to achieve the purpose of low footprint, high compatibility and high efficiency of the cell assembly segment production equipment. Among them, the use of magnetic drive conveying instead of the traditional double-speed chain improves the conveying speed and conveying accuracy, the use of parallel robot gluing improves the efficiency of cell gluing, and the use of roller paper tearing method removes the traditional paper tearing mechanism and improves the paper tearing rhythm.

[0021] The present invention can be divided into the following functions: battery cell online, OCV test & code scanning, online large-surface adhesive peeling, automatic adhesive application, NG automatic replacement, and automatic offline.

[0022] Overall, the present invention realizes the miniaturization method of battery cell assembly equipment, and the equipment integrates the functions of automatic battery cell loading, battery cell OCV testing & code scanning, automatic battery cell gluing, NG replacement, and automatic battery cell unloading. The biggest advantage is that it effectively reduces the footprint of the assembly equipment, and while ensuring efficiency, it also takes into account the battery cell compatibility range; in addition, in terms of module formula logic, it can achieve one-click switching from series mode to parallel mode.

[0055] In order to clearly illustrate the technical features of this patent, this patent is elaborated in detail below through a specific implementation method and in combination with its accompanying drawings.

[0056] This case can be divided into the following functions: battery cell online, OCV test & code scanning, online large-surface adhesive peeling, automatic adhesive application, NG automatic replacement, and automatic offline. Specifically:

[0057] In step 1, the battery cells are transported to the extrusion platform 21 of the battery cell on-line mechanism 2. The extrusion platform 21 centers and pushes the battery cells until they are blocked by a blocking block. The transfer robot 24 grabs two battery cells and arranges them on the transfer platform 23.

[0058] In step 2, the online robot 3 grabs two battery cells and places them on two battery cell fixtures 53 of the magnetic drive conveying mechanism 5, and starts conveying. After the battery cells arrive at the OCV detection mechanism 4, the OCV detection mechanism 4 descends to perform the battery cell OCV test and scan the code.

[0059] Step 3: The first six-axis manipulator 62 grabs the large-surface adhesive tape, moves it to the inclined roller adhesive peeling table 63, and peels off the stickers on both sides of the large-surface adhesive tape.

[0060] Step 4, the glue gripper 64 grabs the large-surface glue after the sticker is torn off, and puts it into the flat roller conveyor belt 65, performs CCD correction, and the automatic glue sticking mechanism 7 takes the material, and after waiting for the battery cell to be transported, the automatic glue sticking mechanism 7 performs glue sticking.

[0061] In step 5, the battery cells are transported to the area where the NG replacement mechanism 8 is located. If NG material exists, the second six-axis robot 83 puts the NG material into the NG material conveyor belt 81 and sends it out, and takes out the OK material from the OK material temporary storage table 82 to replace the NG material.

[0062] Step 6: The battery cells are transported to the area where the offline robot 9 is located. The positive and negative poles of the battery cells are checked and adjusted as required to complete the offline process.

[0063] The overall appearance and structure of this case is as follows Figure 1 , 2 As shown, it includes a host 1 and a battery cell online mechanism 2 installed next to the host; the host 1 is provided with an online robot 3, an OCV detection mechanism 4, a magnetic drive conveying mechanism 5, a large-surface glue peeling mechanism 6, an automatic glue sticking mechanism 7, an NG replacement mechanism 8 and an offline robot 9.

[0064] like Figure 3 , 4 As shown, the magnetically driven conveying mechanism 5 is a magnetic suspension conveying chain, which includes an annular track 51 fixedly installed in the main machine 1 and a magnetic suspension slider 52 slidably installed on the annular track 51, and each magnetic suspension slider 52 is installed with a battery cell tooling 53 for clamping the battery cell; this case changes the traditional battery cell conveying method, and adopts a magnetic suspension conveying chain with faster speed and higher position accuracy to convey the battery cells, and the position of each magnetic suspension slider can be independently controlled and adjusted during the working process.

[0065] like Figure 5 , 6 As shown, the magnetic suspension slider 52 is C-shaped and is inserted at the edge of the annular track 51 .

[0066] About battery tooling:

[0067] like Figure 7 , 8 As shown, the battery tooling 53 includes a base 531, a fixed stopper 532, a floating stopper 533 and a back stopper 534. The base 531 is fixedly mounted on the top surface of the magnetic suspension slider 52. The fixed stopper 532 and the movable stopper 533 are respectively used to clamp two small surfaces of the battery cell, and the back stopper 534 is used to resist the large surface of the back side of the battery cell.

[0068] The base 531 is fixedly mounted with a first guide rail 5311 designed parallel to the large surface of the battery cell and a second guide rail 5312 designed parallel to the small surface of the battery cell. The bottom of the fixed stopper 532 is slidably connected to the first guide rail 5311, and the fixed stopper 532 is detachably mounted on the base 531. The bottom of the back stopper 534 is slidably connected to the second guide rail 5312, and the back stopper 534 is also detachably mounted on the base 531.

[0069] A third guide rail 5313 parallel to the first guide rail 5311 is fixedly mounted on the base 531, and the bottom of the floating stopper 533 is slidably connected to the third guide rail 5313;

[0070] A fixed block 535 fixedly mounted on the base 531 and a compression spring between the fixed block 535 and the floating block 533 are provided on the side of the floating block 533 facing away from the center of the base 531, so that the floating block 533 maintains a movement trend toward the center of the base 531;

[0071] A fourth guide rail 5314 is also provided between the first guide rail 5311 and the third guide rail 5313 and is perpendicular to the first guide rail 5311 and the third guide rail 5313. A stopper slide bar 536 is provided on the side of the floating stopper 533 facing the center of the base 531 and is slidably connected to the fourth guide rail 5314. An oblique guide groove 5361 is provided on the stopper slide bar 536. A guide column is inserted into the oblique guide groove 5361. The floating stopper 533 is fixedly connected to the guide column. Under the action of the compression spring, the floating stopper 533 pushes the guide column toward the center of the base 531 and forces the stopper slide bar 536 to translate.

[0072] like Figure 6 , 7 As shown in Figures 8 and 8, an electromagnetic unlocker 510 for unlocking the battery cell tooling 53 is also fixedly installed on the annular track 51. The electromagnetic unlocker 510 is located on the inner side of the movement trajectory of the stop slide 536 and is arranged outward. The center of the end of the stop slide 536 has a magnetic pole. When the electromagnetic unlocker 510 is energized, it generates the same magnetic pole as the end of the stop slide 536, so that the stop slide 536 overcomes the force of the compression spring and moves along the fourth guide rail 5314, thereby forcing the floating stop block 533 to move away from the center of the base 531 under the guidance of the oblique guide groove 5361.

[0073] like Figure 6 As shown, the electromagnetic unlocker 510 is provided in plurality, two of which are provided below the upper line robot 3 and the lower line robot 9 respectively, and at least one is provided in the area where the NG replacement mechanism 8 is located.

[0074] Before loading the battery cell, the staff can pre-adjust the position of the fixed block 532 and the back block 534 according to the size of the battery cell, and lock them, so that the battery cell tooling can adapt to a variety of battery cells of different specifications. During operation, driven by the magnetic suspension slider, the two battery cell tooling will first enter the area where the online manipulator is located. At this time, the stop slide 536 in the two battery cell tooling will be located on the outside of the two electromagnetic unlockers 510. After the electromagnetic unlocker 510 is turned on to force the floating block 533 to slide outward and open, the battery cell can be placed. After the battery cell is placed, the driving force of the electromagnetic unlocker 510 on the stop slide 536 is released, so that the compression spring can push the floating block 533 to reset, and the elastic force of the compression spring can stably clamp the battery cell and expose the large outer surface that needs to be glued.

[0075] When the two battery cell jigs are driven by the magnetic levitation slider into the area where the unloading robot is located, the electromagnetic unlocker 510 is turned on to force the floating block 533 to slide outward and open, and then the battery cells can be taken out; similarly, when the battery cells loaded on the battery cell jigs are NG materials, the battery cells can be loosened or clamped in the area where the NG replacement mechanism 8 is located.

[0076] About the circular track:

[0077] like Figure 4 As shown, the circular track 51 has two straight segments and two arc segments, the upper line robot 3 and the lower line robot 9 are located above one of the straight segments, and the OCV detection mechanism is located above one of the arc segments; the other straight segment of the circular track 51 passes through the area where the automatic glue sticking mechanism 7 and the NG replacement mechanism 8 are located, the large surface glue peeling mechanism 6 is located beside the automatic glue sticking mechanism 7, and the total length of the area where the large surface glue peeling mechanism 6, the automatic glue sticking mechanism 7, and the NG replacement mechanism 8 are located is close to the overall length of the circular track 51. This makes the overall structure more compact and occupies less space.

[0078] like Figure 3 , 4 As shown, the circular track 51 passes through the areas where the on-line robot 3, the OCV detection mechanism 4, the automatic glue sticking mechanism 7, the NG replacement mechanism 8 and the off-line robot 9 are located in sequence;

[0079] The on-line manipulator 3 is used to grab the battery cells transported by the battery cell on-line mechanism 2 and place them on a battery cell fixture 53; the OCV detection mechanism 4 is used to perform OCV detection on the battery cells that pass through; the large-surface glue peeling mechanism 6 is arranged next to the automatic glue sticking mechanism 7, and the stickers on the large-surface glue are peeled off by the large-surface glue peeling mechanism 6; the automatic glue sticking mechanism 7 is used to grab the large-surface glue with the stickers peeled off and stick it on the large surface of the battery cells that pass through; the NG replacement mechanism 8 is used to replace the NG materials that pass through with OK materials; the offline manipulator 9 is used to take away the processed battery cells on the battery cell fixture 53. Therefore, after the battery cells are put online, as the magnetic drive conveying mechanism transports the battery cells, the production operations of OCV testing & code scanning, online peeling of large-surface glue, automatic glue sticking, and NG automatic replacement are gradually carried out, and the OK materials are controlled to stably go offline after processing is completed.

[0080] About the cell launch organization:

[0081] like Fig. 9 As shown, the cell loading mechanism 2 includes an extrusion table 21, a blocking block 22, a transfer table 23, and a transfer robot 24 for transferring the cell on the extrusion table 21 to the transfer table 23; the specific processing route is:

[0082] The extrusion table feeds the cells → the blocking mechanism blocks → the transfer robot grabs the cells and moves them to the top of the transfer table → the transfer table arranges the cells in a row with variable pitch. Specifically:

[0083] like Fig.10 , 11 As shown in , 12, the extrusion platform 21 includes an extrusion platform 211, a pushing mechanism 212 and a centering mechanism 213;

[0084] The extrusion table 211 is provided with a material pushing channel 2111 and a cell slide rail 2112 arranged along its length direction;

[0085] The pushing mechanism 212 includes a pushing linear module 2121 fixedly installed under the extrusion table 211 and a pushing block 2122 running through the pushing channel 2111. The pushing linear module 2121 is arranged parallel to the pushing channel 2111, and the pushing block 2122 is fixedly installed on the output of the pushing linear module 2121.

[0086] The centering mechanism 213 includes a centering motor 2131, a centering screw 2132, two centering nuts 2133 and two centering baffles 2134. The two centering baffles 2134 are slidably installed on both sides of the battery slide rail 2112, and are fixedly connected with the two centering nuts 2133 through connecting rods respectively. The centering screw 2132 is rotatably connected under the extrusion table 211 and is arranged along the width direction of the extrusion table 211. The centering screw 2132 is symmetrically provided with two sections of threads with opposite rotation directions, and is threadedly connected with the two centering nuts 2133 at the same time through the two sections of threads. The centering motor 2131 is fixedly installed under the extrusion table 211 and is linked with the centering screw 2132. In this way, when multiple battery cells are stacked on the battery cell slide rail 2112, the centering motor 2131 can be turned on first, so that the two centering nuts 2133 are close to each other under the influence of the reverse threads, thereby driving the two centering bars 2134 to align the battery cells from both sides to the center of the extrusion table 211, so that the center of the battery cell is at a predetermined position. Moreover, even when facing battery cells of different sizes, this type of centering mechanism can also achieve accurate alignment of the battery cells.

[0087] like Fig.10 As shown, the blocking block 22 is fixedly mounted at the end of the pushing channel 2111. In this way, after the plurality of cells are aligned, the pushing linear module 2121 is turned on, and the pushing block 2122 can be controlled to push the entire row of cells toward the blocking block 22, waiting for the transfer robot 24 to grab.

[0088] like Fig. 9 As shown, the transfer robot 24 is a three-axis robot, which is used to transfer the battery cells on the extrusion table 21 to the transfer table 23. Furthermore, the execution end of the transfer robot 24 has two battery cell clamps, so that the transfer of two battery cells can be completed at the same time through one grabbing.

[0089] like Fig.13 , 14 As shown, the transfer table 23 includes a transfer table 231, a translation carrier 232 and a push carrier 233. The transfer table 231 is fixedly mounted with mutually perpendicular translation rails 2311 and a push rail 2312. The translation carrier 232 is slidably mounted on the translation rail 2311, and the push carrier 233 is slidably mounted on the push rail 2312.

[0090] A translation linear module and a push linear module are also fixedly installed on the transfer table 231. The translation linear module is arranged parallel to the translation slide rail 2311, and its output end is fixedly connected to the translation carrier 232; the push linear module is arranged parallel to the push slide rail 2312, and its output end is fixedly connected to the push carrier 233. In this way, after the transfer robot 24 puts two battery cells in the translation carrier 232 and the push carrier 233 respectively, the translation linear module first drives the translation carrier 232 to translate and make way, and then the push linear module drives the push carrier 233 to push forward, so that the two battery cells are arranged adjacently on the transfer table, waiting to be put online.

[0091] like Fig.14 As shown, the output end of the translation linear module is fixedly connected to the translation carrier 232 through a translation push block 2313, and a pair of translation limit blocks 2315 are fixedly installed on the front end surface of the transfer table 231, and the pair of translation limit blocks 2315 are located at both ends of the movement path of the translation push block 2313, thereby limiting the movement of the translation push block 2313.

[0092] The output end of the pushing linear module is fixedly connected to the pushing carrier 233 through a pushing block 2314, and a pair of pushing limit blocks 2316 are fixedly installed on the side end surface of the transfer table 231. The pair of pushing limit blocks 2316 are located at both ends of the movement path of the pushing block 2314, thereby limiting the movement of the pushing block 2314.

[0093] After two battery cells are arranged adjacent to each other in a row on the transfer table, the battery cell loading robot grabs two battery cells from the transfer table and loads them onto the magnetic drive battery cell conveying tooling.

[0094] About the online robot:

[0095] like Fig.15 As shown, the on-line robot 3 includes a two-axis robot 31 and a pair of on-line clamps 32 installed at the output end of the two-axis robot 31, and the pair of on-line clamps 32 are arranged in parallel;

[0096] The on-line fixture 32 includes a first direction adjustment motor 321, a first double-acting cylinder 322, and a pair of first clamping fingers 323. The housing of the first direction adjustment motor 321 is fixedly mounted on the output end of the two-axis manipulator 31. The center of the cylinder body of the first double-acting cylinder 322 is fixedly mounted on the output shaft of the first direction adjustment motor 321. The pair of first clamping fingers 323 are respectively fixedly connected to the two cylinder rods of the first double-acting cylinder 322. Thus, two battery cells arranged in a row adjacent to each other on the transfer table can be conveniently grasped as a whole, and finally transferred to the two battery cell fixtures 53 in the magnetic drive conveying mechanism 5. In addition, due to the presence of the first direction adjustment motor 321, the production line can adjust the positive and negative poles of the battery cells as required, so that the electrodes of adjacent battery cells are the same or opposite, so as to facilitate subsequent series installation or parallel installation.

[0097] About OCV inspection machine:

[0098] like Figure 4 As shown, the battery tooling flows along the direction of the magnetic drive to the OCV test & code scanning station, wherein the OCV detection mechanism 4 includes an OCV probe that can be raised and lowered and installed on a circular track. The OCV probe has two groups, and the OCV probe is used to detect the battery cells passing through, thereby distinguishing NG materials from OK materials, that is, unqualified products from qualified products. Since such OCV detection means and equipment are existing technologies in this field, they will not be described in detail in this case.

[0099] About the large surface glue peeling mechanism:

[0100] like Figure 4 , 16 As shown, the large-surface glue peeling mechanism 6 includes a glue storage table 61, a first six-axis manipulator 62, an inclined roller glue peeling table 63, a glue outlet gripper 64 and a flat roller conveyor belt 65;

[0101] The first six-axis manipulator 62 is used to grab the large-surface adhesive in the adhesive storage table 61 and place it on the inclined roller adhesive peeling table 63. The inclined roller adhesive peeling table 63 is used to transport and peel off the stickers on the large-surface adhesive. The flat roller conveyor belt 65 is arranged in the same direction as the inclined roller adhesive peeling table 63. The adhesive outlet gripper 64 is used to grab the large-surface adhesive after the stickers are peeled off and put it into the flat roller conveyor belt 65.

[0102] In particular, the execution end of the first six-axis manipulator 62 is equipped with a large-surface adhesive fixture, the execution end of the adhesive gripper 64 is equipped with a large-surface adhesive suction cup connected to a negative pressure source, and the surface of the large-surface adhesive suction cup is treated with anti-sticking.

[0103] like Fig.19As shown in the figure, the large-surface adhesive tape mentioned above has two sides with sticky adhesive surfaces, and stickers are attached to the adhesive surfaces to facilitate the storage and transportation of the large-surface adhesive tape before use; when the large-surface adhesive tape needs to be processed, the stickers are torn off to expose the adhesive surface. Furthermore, in order to facilitate the peeling of the sticker, a peeling angle is usually set on the edge of the sticker, so that the sticker can be easily peeled off by pulling the peeling angle.

[0104] like Fig.17 , 20 As shown in 21, 22, and 23, the inclined roller glue peeling station 63 includes a roller conveyor belt 631 and two glue peeling mechanisms 632 arranged in front and back;

[0105] Taking into account that the friction coefficient of the large-surface adhesive tape is not large when carrying stickers, in order to ensure the stable transportation of the large-surface adhesive tape, the roller conveyor belt 631 includes a plurality of inclined rollers 6311 and an inclined roller power source, and the inclined roller power source drives the plurality of inclined rollers 6311 to rotate around their own axes, thereby stably conveying the large-surface adhesive tape carried on their surfaces; a guide plate 633 for positioning is also installed on the roller conveyor belt 631, and the guide plate 633 is perpendicular to the inclined rollers 6311, and a pair of mounting guide posts 634 are fixedly connected to the upper side of the guide plate 633, and the mounting guide posts 634 are detachably installed on the upper side of the roller conveyor belt 631; so that when the large-surface adhesive tape passes by, the upper edge of the large-surface adhesive tape is pressed, which plays a good guiding and positioning role for the large-surface adhesive tape, so as to facilitate the subsequent accurate adhesive removal.

[0106] A row of guide rollers 6312 is also provided above the inclined rollers 6311. Both ends of the guide rollers 6312 are rotatably connected to the roller conveyor belt 631 and are arranged parallel to the inclined rollers 6311, thereby forming a glue removal work area between the guide rollers 6312 and the inclined rollers 6311.

[0107] The adhesive peeling mechanism 632 includes an air blowing nozzle 6322 and a paper receiving bin 6321 located at the upper and lower sides of the adhesive peeling working area. The air blowing nozzle 6322 blows air from the gap between the inclined roller or the guide roller to the adhesive peeling working area. The bin opening of the paper receiving bin 6321 is arranged opposite to the blowing position of the air blowing nozzle 6322.

[0108] The two glue peeling mechanisms 632 are arranged in sequence, and the air blowing nozzles 6322 in the two are located in opposite positions, that is, at the upper and lower sides of the glue peeling working area. Fig. 20 , 21 As shown in Figures 22 and 23, as the large-surface adhesive enters the adhesive peeling work area, the air from the air blowing nozzle 6322 will first blow the adhesive peeling of the sticker out of the adhesive peeling work area, and as the large-surface adhesive continues to move forward, it will gradually drive the sticker out of the adhesive peeling work area and enter the paper collection bin 6321. Finally, under the joint influence of the front and back adhesive peeling mechanisms, the stickers on both sides of the large-surface adhesive are efficiently peeled off.

[0109] like Fig.16 , 17 As shown in Figure 18, the glue discharging gripper 64 includes a swing arm and a swing arm power source, which drives the swing arm to swing back and forth between the flat roller conveyor belt 65 and the idler roller conveyor belt 631, and a large-surface glue suction cup connected to a negative pressure source is fixedly installed at the bottom end of the swing arm.

[0110] like Fig.16 , 17 As shown in FIG. 18 , the flat roller conveyor belt 65 includes a plurality of horizontally arranged flat rollers and a flat roller power source. The flat roller power source drives the plurality of flat rollers to rotate around their own axes, thereby stably conveying the large-surface rubber carried on their surfaces. The surfaces of the flat rollers are treated with anti-sticking.

[0111] About the automatic glue sticking mechanism:

[0112] like Figure 4 , 16 As shown, the automatic gluing mechanism 7 is a spider manipulator, which grabs the large-surface adhesive after the sticker is torn off and sticks it on the large surface of the battery cell. The execution end of the spider manipulator is fixedly equipped with a suction cup connected to a negative pressure source, and the surface of the suction cup is treated with anti-sticking.

[0113] CCD cameras are also installed on the flat roller conveyor belt and the gluing position to detect whether the sticker has been torn off and whether the subsequent gluing has been completed.

[0114] About NG replacement mechanism:

[0115] like Figure 4 As shown, the NG replacement mechanism 8 includes an NG material conveyor belt 81, an OK material temporary storage table 82 and a second six-axis manipulator 83. The execution end of the second six-axis manipulator 83 is equipped with a battery cell clamp. The second six-axis manipulator 83 is used to transfer battery cells between the magnetically driven conveying mechanism 5, the NG material conveyor belt 81 and the OK material temporary storage table 82. The NG material conveyor belt 81 is used to deliver NG materials.

[0116] The working logic of the NG replacement mechanism is:

[0117] Considering that the battery cells are processed in pairs each time, it is necessary to ensure that the number of OK materials in the OK material temporary storage table 82 is not less than 2.

[0118] During the specific work, the first batch of qualified products will be temporarily stored in the OK material temporary storage table 82, and the unqualified products will be directly placed in the NG material conveyor belt 81 and sent out until the number of OK materials in the OK material temporary storage table 82 is greater than or equal to 2; thereafter, whenever there is NG material in the paired battery cells, the OK material will be taken out from the OK material temporary storage table 82 to replace the NG material; when the number of OK material in the OK material temporary storage table 82 is less than 2, the OK material will be replenished until the number of OK material in the OK material temporary storage table 82 is greater than or equal to 2.

[0119] About offline robot:

[0120] like Fig.15 As shown, the offline robot 9 includes a three-axis robot 91 and a pair of offline clamps 92 installed at the output end of the three-axis robot 91, and the pair of offline clamps 92 are arranged in parallel;

[0121] The offline clamp 92 includes a second direction adjustment motor 921, a second double-acting cylinder 922, and a pair of second clamping fingers 923. The housing of the second direction adjustment motor 921 is fixedly mounted on the output end of the three-axis manipulator 91. The center of the cylinder body of the second double-acting cylinder 922 is fixedly mounted on the output shaft of the second direction adjustment motor 921. A pair of second clamping fingers 923 are respectively fixedly connected to the two cylinder rods of the second double-acting cylinder 922. Thus, two processed battery cells arranged adjacent to each other in a row by the magnetic drive conveying mechanism can be conveniently grasped as a whole, and finally transported for offline. In addition, due to the presence of the second direction adjustment motor 921, the production line can review and adjust the positive and negative poles of the battery cells when offline as required, so that the electrodes of adjacent battery cells are the same or opposite, so as to facilitate subsequent series installation or parallel installation.

[0122] There are many specific implementation ways of the present invention. The above is only the preferred implementation mode of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention. These improvements should also be regarded as the protection scope of the present invention.
