The utility model will be described in detail below with reference to the drawings in connection with embodiments.

The present embodiment relates to a lamination apparatus, which, in an overall structure, as shown in fig. 1 to 5, includes a lamination mechanism, a first feeding mechanism 31 for conveying a first pole piece 21 to the lamination mechanism, and a second feeding mechanism 32 for conveying a second pole piece 22 to the lamination mechanism, where the first feeding mechanism 31 and the second feeding mechanism 32 are respectively disposed on both sides of the lamination mechanism in a width direction, and waste rejecting and patch mechanisms are respectively disposed on both sides of the lamination mechanism in the width direction.

The lamination mechanism comprises a plurality of lamination platforms 11 which are arranged at intervals along the length direction, and lamination robot assemblies which are arranged corresponding to the lamination platforms 11, wherein each lamination robot assembly can grasp the first pole piece 21 and the second pole piece 22 and convey the first pole piece and the second pole piece to the corresponding lamination platform 11 for alternate lamination.

Of course, the above-mentioned arrangement relationship of the magnetic levitation annular rail 33 and the mover assembly can refer to a magnetic levitation conveying system commonly known in the art, for example, a stator assembly for magnetically levitated driving cooperation with the mover assembly is integrated on the magnetic levitation annular rail 33.

The first and second electrode sheets 21 and 22 of this embodiment refer to a negative electrode sheet unit and a positive electrode sheet for lamination, respectively, and the negative electrode sheet unit herein refers to a negative electrode sheet bag (the separator is provided on both sides of the negative electrode sheet, and the separator on both sides encapsulates the electrode sheets together as an integrated body). In the state shown in fig. 1, the width direction of the present embodiment is perpendicular to the length direction.

Meanwhile, it should be mentioned that in the present embodiment, the first feeding mechanism 31 and the second feeding mechanism 32 have substantially the same structural form, and can be regarded as being disposed in mirror image with the central line of each lamination stage 11 as an axis, and the difference is that only the first feeding mechanism 31 is used for transferring the first pole piece 21, and only the second feeding mechanism 32 is used for transferring the second pole piece 22.

In this embodiment, as a preferred implementation manner, as shown in fig. 3, the rejecting and patching mechanism includes a scrap station 61 for storing the first pole piece 21 or the second pole piece 22 of NG, and a patching station 62 for storing the qualified first pole piece 21 or the second pole piece 22, where the scrap station 61 and the patching station 62 can be reciprocally slid along the length direction along with the rejecting and patching robot 63 under the driving of the first driving part.

The arrangement of the waste station 61 and the patch station 62 can lead the structural arrangement of the waste rejecting and patch mechanism to be reasonable, and is beneficial to ensuring the efficiency of waste rejecting and patch. The first driving part may adopt a structure similar to that of the magnetic levitation conveying line, so as to improve the driving precision and efficiency of the reject and patch robot 63, the reject station 61 and the patch station 62 in a magnetic levitation driving manner.

Furthermore, as a preferred implementation form, the reject and patch mechanism includes a guide rail 64 extending in the length direction, and the reject and patch robot 63 is slidably disposed on the guide rail 64, so as to facilitate the improvement of the sliding stability of the reject and patch robot 63. Of course, the scrap station 61 and the patch station 62 also slide on the rail 64, based on the consideration of the sliding stability of the scrap station 61 and the patch station 62.

In a specific structure, as a preferred implementation manner, with continued reference to fig. 1, the guide rail 64 of the present embodiment is located in the magnetic suspension annular track 33, so that the occupied space of the lamination device can be saved, the compactness of the device is improved, and the miniaturization design is facilitated.

In addition, in this embodiment, as a preferred implementation manner, the magnetic suspension annular track 33 is provided with a material taking area 34 close to the lamination mechanism, and a material loading area 35 arranged upstream of the material taking area 34, and each sub-assembly can receive the first pole piece 21 or the second pole piece 22 at the material loading area 35 and convey to the material taking area 34 for grabbing by the lamination robot assembly.

Specifically, as a preferred implementation manner, the magnetic suspension annular rail 33 of the present embodiment is provided with a buffer area 36 located between the material taking area 34 and the material loading area 35, and the buffer area 36 is used for buffering each sub-assembly sliding from the material loading area 35 to the material taking area 34.

Through the cooperation of material loading district 35, get material district 34 and buffer 36, do benefit to the conveying efficiency with the magnetic suspension transfer chain body and lamination operation control of lamination mechanism in better cooperation frequency, and then effectively promote lamination efficiency.

Meanwhile, considering the requirement of improving the lamination efficiency, in this embodiment, as a preferred implementation manner, as shown in fig. 1 and 2, a material taking station 341 corresponding to each lamination stage 11 is disposed in the material taking area 34, each material taking station 341 can accommodate at least two sub-assemblies, and each lamination stage 11 is provided with at least two lamination stations 111.

The lamination robot assembly comprises a lamination robot 12 arranged between the corresponding lamination stage 11 and the material taking station 341, and the lamination robot 12 can grasp the first pole piece 21 or the second pole piece 22 on each sub-assembly from the material taking station 341 and respectively place the first pole piece 21 or the second pole piece 22 on each lamination station 111 in the corresponding lamination stage 11.

It can be appreciated that the lamination stations 111 are disposed on the lamination table 11, and the material taking stations 341 and the lamination robots 12 are disposed corresponding to the lamination stations 111, so that pole piece transferring, pole piece carrying and lamination operation are coordinated on a better operation rhythm, and lamination efficiency is further improved.

In this embodiment, as a preferred implementation manner, as shown in fig. 2, the detecting portion includes first CCD camera assemblies 41 respectively corresponding to the material taking stations 341. Of course, in a specific structure, the first CCD camera assembly 41 is preferably configured to include two first CCD camera units, where the two first CCD camera units respectively correspond to two ends of the sub-assembly at the material taking station 341 (i.e. two ends of the first pole piece 21 or the second pole piece 22 at the material taking station 341), so as to ensure the deviation rectifying and positioning effects.

Meanwhile, as a preferred embodiment, with continued reference to fig. 2, in this embodiment, two sides of each lamination stage 11 in the width direction are respectively provided with a second CCD camera assembly 51, and the second CCD camera assembly 51 is used for visually positioning the first pole piece 21 or the second pole piece 22 when lamination is performed.

Here, the use of the first CCD camera assembly 41 and the second CCD camera assembly 51 has the advantages of simple structure, mature product and high use stability, and meanwhile, the second CCD camera assembly 51 is arranged, so that a mechanism for positioning the pole piece is not required to be arranged on the lamination table 11, that is, lamination operation can be realized by using the lamination table 11 with the lamination station 111, and cost of the lamination table 11 can be reduced.

In addition, as an exemplary structure, as shown in fig. 4 and 5, the lamination mechanism includes a moving slide rail 13 extending in the longitudinal direction, and a second driving portion capable of driving each lamination stage 11 to reciprocally slide along the moving slide rail 13, respectively.

It will be appreciated that the arrangement of the movable slide 13 and the second driving portion enables separate driving of each lamination station 11, facilitating the arrangement of the lamination stations 11 before lamination and the collective blanking after lamination.

Of course, in the implementation, the manner of driving each lamination table 11 by the second driving portion may be implemented by using a conventional means, for example, the rack 14 may be specifically disposed on one side of the moving slide rail 13, the second driving portion includes a driving motor disposed on each lamination table 11, and a driving gear capable of meshing with the rack 14 is connected to the driving of each driving motor, and by making the types of the driving gears different, the sliding speeds of each lamination table 11 are different, so that the respective driving of each lamination table 11 and the parking at different positions are implemented.

When the lamination device of the embodiment is specifically arranged and laid out, each sub-assembly can carry two pole pieces (the first pole piece 21 or the second pole piece 22), six lamination platforms 11 are configured, one lamination robot assembly (i.e. two lamination robots 12 for twelve lamination robots 12) is configured at each lamination platform 11, and two lamination stations 111 are respectively arranged on each lamination platform 11, so as to realize the design of a split type double-station lamination platform.

Subsequently, the interval between each lamination table 11 (lamination robot assembly) is set to 1750mm, and then the design form that each lamination table 11 can be independently laminated with 1750mm interval components of a whole that can function independently in the lamination process is realized, simultaneously through the cooperation setting of transfer slide rail and drive portion for each lamination table 11 after the lamination is accomplished can be at the unloading district (set up the one end that removes slide rail 13 and keep away from the lamination district) simultaneously fit the unloading with 175 mm's station interval.

In addition, in the structural layout of the lamination device, two reject and patch mechanisms can be arranged, and the reject and patch mechanisms respectively correspond to the first feeding mechanism 31 and the second feeding mechanism 32 so as to finish reject and patch operations of corresponding pole pieces (the first pole piece 21 or the second pole piece 22), and when the lamination device is specifically implemented, the reject and patch robots, the waste station 61 and the patch station 62 in the two reject and patch mechanisms can be adjusted along the position of the length direction, so that the operation beat is further facilitated to be improved.

Therefore, compared with the traditional scheme design adopting a pair of four-station manipulators and an integrated eight-station lamination table, the scheme design adopting a four-axis robot carrying, deviation correcting and double-station lamination mode can break through the limit of 480ppm limit lamination efficiency, realize 1000ppm lamination efficiency, namely solve the problem of efficiency bottleneck existing in the prior scheme using the eight-station lamination table 11 based on picking and placing manipulator carrying, CCD vision, UVW alignment platform positioning and the like.

During lamination, the first feeding mechanism 31 and the second feeding mechanism 32 respectively receive the pole pieces (the first pole piece 21 and the second pole piece 22) transferred from the previous process in the respective feeding areas 35, and each sub-assembly is connected with two pieces. Each sub-assembly after the sheet connection moves to a buffer area 36 through a magnetic suspension annular track 33, five sub-assemblies in the buffer area 36 and one sub-assembly in a (6) number material taking station 341 (from left to right, in turn, (1) - (6) material taking station 341) form a sub-module, each sub-module carries twelve pole pieces, each time one sub-module is advanced, namely, the distance between the six sub-assemblies is kept, and the sheet feeding is carried out on all lamination robots 12.

After the lamination robot 12 at the material taking station 341 in (1) has taken out the last two pole pieces of one sub-module, the six sub-modules of the sub-module move to the material receiving area for material receiving. After each sub-module is fed in place, the lamination robot 12 adjusts the pole piece posture by means of the visual positioning parameters of the first CCD camera assembly 41, the correction of the pole piece is completed, then the piece taking is carried out, the double-station piece taking is completed in two times, and after the piece taking is completed, the lamination robot 12 carries the lamination to the lamination table 11 to alternately laminate the positive pole piece and the negative pole piece (the first pole piece 21 and the second pole piece 22).

If pole piece NG appears in the robot material taking process, the lamination robot 12 stops, and the scrap removing and patch robot 63 moves to the NG position by means of a magnetic levitation track to remove scrap patches. After the pole pieces in the pole groups of all the lamination platforms 11 reach the set value, the lamination robot 12 stops, and the lamination platforms 11 translate and discharge by means of the movable slide rail 13. In the blanking moving process of the lamination platforms, all lamination platforms 11 are combined and moved to a blanking area together with a station spacing of 175mm, after the blanking is completed, the lamination platforms 11 return according to the original track, are separated and returned to the respective lamination positions in the moving process, the spacing is kept at 1750mm, and then new pole group lamination is carried out.

It should be noted that, in the process of rejecting the patch, the rejecting and patch robot 63 needs to determine whether the patch station 62 has a patch, if so, it directly moves to NG to perform rejecting patch operation, and if not, the rejecting and patch robot 63 moves to the pole piece feeding area 35 to directly take two pieces of pole pieces and place them on the patch station 62. After the sheet is taken out, the reject and patch robot 63 moves to the NG position to take out the NG sheet and place the NG sheet on the scrap station 61, and then the qualified sheet on the patch station 62 is placed at the position of the sheet NG, so that the patch is completed.

According to the lamination equipment, based on the grabbing flexibility of the lamination robot assembly and the matching of the postures of the first pole piece 21 or the second pole piece 22 which can be positioned by the detection part, the pole piece deviation rectifying and positioning functions can be realized on the basis of carrying functions, compared with the mode that a manipulator and a UVW alignment platform are matched for deviation rectifying and positioning in the prior art, the lamination section width is greatly reduced, further enough space can be reserved for pole piece transportation, and the pole piece transportation efficiency is improved by combining the matching use of magnetic suspension conveying line bodies for both the first feeding mechanism 31 and the second feeding mechanism 32;

meanwhile, compared with the existing design mode of the mechanical arm and the integrated lamination table 11, the lamination process between the lamination tables 11 is not interfered, so that the risk of sheet falling is reduced, the logic complexity of waste picking and sheet repairing is reduced, the length of the waste picking and sheet repairing time is reduced, the operability is better, the positions of the waste picking and sheet repairing robot 63 in the length direction are adjustable, the efficiency of waste picking and sheet repairing can be improved, and the efficiency limit of the existing lamination mode is favorably broken through.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
