Description

Lamination equipment

Technical field

Background technique

At present, the production methods of lithium batteries are mainly divided into two methods: winding and lamination. Compared with the winding method, the cells produced by the lamination method have higher energy density and better quality, and the lamination process is called lamination production. The key to the method determines to a large extent the production efficiency and product quality of laminated lithium batteries.

In the thermal composite lamination method, the lamination process is to transport the positive and negative electrode sheets through the vacuum belt. After CCD visual inspection and UVW alignment platform positioning, the positive and negative electrode sheets are placed on the lamination table by a pick-and-place robot. Alternately laminate until the pole group on the lamination table reaches the set number of pole pieces, and the lamination table starts unloading.

In the existing thermal composite lamination method, pick and place robots are usually used for transportation, and the lamination method of CCD vision and UVW alignment positioning is used.

The stacking method is single and requires CCD vision and UVW alignment platforms to position the pole pieces at the same time. The stacking efficiency is low. At the same time, the structure of the stacking equipment is complex and the reserved space for pole piece transfer is small, resulting in handling efficiency and difficulty. repair.

Sub-assembly, each mover sub-assembly is equipped with a first pole piece 21 or a second pole piece 22.

The use of magnetic levitation ring track 33 in the magnetic levitation conveying line body facilitates the arrangement and coordination between the first loading mechanism 31, the second loading mechanism 32 and the stacking mechanism, and has a better arrangement effect.

Of course, the above-mentioned arrangement relationship between the magnetic levitation ring track 33 and the mover assembly can refer to the common magnetic levitation transportation system in the prior art. For example, the magnetic levitation ring track 33 is integrated with a stator assembly for magnetic levitation driving cooperation with the mover assembly.

In the state shown in Figure 1, the width direction and the length direction of this embodiment are perpendicular.

At the same time, it should be mentioned that in this embodiment, the structural forms of the first loading mechanism 31 and the second loading mechanism 32 are basically the same, and they can be regarded as mirror images with the center line of each stacking table 11 as the axis. The only difference is that the first loading mechanism 31 is used to transfer the first pole piece 21 , and the second loading mechanism 32 is used to transfer the second pole piece 22 .

The robot 63 slides back and forth along the length direction.

The setting of the waste material station 61 and the patching station 62 here can make the structure arrangement of the waste removal and patching mechanism reasonable and help ensure the efficiency of the waste removal and patching. The first driving part can adopt a structure similar to the magnetic levitation conveying line body to improve the driving accuracy and efficiency of the scrap picking and patching robot 63, the scrap station 61 and the patching station 62 through magnetic levitation driving.

Of course, based on the consideration of the sliding stability of the scrap station 61 and the patch station 62, the scrap station 61 and the patch station 62 also slide on the guide rail 64.

In the specific structure, as a preferred implementation form, continue to refer to Figure 1. The guide rail 64 of this embodiment is located in the magnetic levitation ring track 33, which can save the space occupied by the stacking equipment, improve the compactness of the equipment, and facilitate miniaturization design. .

In addition, in this embodiment, as a preferred implementation form, the magnetic levitation ring track 33 is provided with a pickup area 34 close to the stacking mechanism, and a loading area 35 located upstream of the pickup area 34. Each mover assembly The first pole piece 21 or the second pole piece 22 can be received at the loading area 35 and transported to the picking area 34 for the stacking robot assembly to grab.

Specifically, as a preferred implementation form, the magnetic levitation ring track 33 of this embodiment is provided with a buffer area 36 between the material pickup area 34 and the loading area 35. The buffer area 36 is used to cache the materials from the loading area. 35 slides to each moving subassembly of the material taking area 34.

Through the cooperation of the loading area 35, the unloading area 34 and the buffer area 36, it is helpful to control the transportation efficiency of the magnetic levitation conveyor line and the lamination operation of the lamination mechanism at a better cooperation frequency, thereby effectively improving the lamination efficiency.

At the same time, taking into account the need to improve lamination efficiency, in this embodiment, as a preferred implementation form, as shown in FIGS. 1 and 2 , the material pickup area 34 is provided with material pickup devices corresponding to each stacking table 11 respectively. The work stations 341 are each capable of accommodating at least two mover assemblies, and each lamination stage 11 is provided with at least two lamination stations 111 .

The lamination robot assembly includes a lamination robot 12 located between the corresponding lamination table 11 and the material picking station 341. The lamination robot 12 can grab the first pole on each mover assembly from the material picking station 341. The piece 21 or the second pole piece 22 is placed on each lamination station 111 in the corresponding lamination stage 11 respectively.

It can be understood that multiple lamination stations 111 are provided on the lamination table 11, and multiple picking stations 341 and multiple lamination robots 12 are provided corresponding to each lamination station 111, which facilitates the transfer and transfer of pole pieces. The sheet handling and lamination operations are coordinated at a better operating rhythm, further improving lamination efficiency.

In this embodiment, as a preferred implementation form, as shown in FIG. 2 , the detection part includes a first CCD camera assembly 41 respectively provided corresponding to each material picking station 341 . Of course, in the specific structure, the first CCD camera assembly 41 is preferably configured to include two first CCD camera units, and the two first CCD camera units respectively correspond to both ends of the mover assembly at the material picking station 341 (that is, taking the material). (Both ends of the first pole piece 21 or the second pole piece 22 at the material station 341) to ensure the correction and positioning effect.

At the same time, as a preferred implementation form, continue to refer to Figure 2. In this embodiment, second CCD camera assemblies 51 are respectively provided on both sides of each stacking stage 11 in the width direction. 51 is used to visually position the first pole piece 21 or the second pole piece 22 during lamination.

Here, the use of the first CCD camera assembly 41 and the second CCD camera assembly 51 has the advantages of simple structure, mature products, and high stability of use. At the same time, the arrangement of the second CCD camera assembly 51 eliminates the need for lamination. A mechanism for positioning the pole pieces is provided on the table 11, that is, the lamination operation can be realized by using the lamination table 11 with a lamination station 111, which can reduce the cost of the lamination table 11.

In addition, as an exemplary structure, as shown in FIGS. 4 and 5 , the stacking mechanism includes a moving slide rail 13 extending along the length direction, and can drive each stacking table 11 to reciprocate along the moving slide rail 13 respectively. of the second drive unit.

It can be understood that the arrangement of the moving slide rail 13 and the second driving part can realize the separate driving of each lamination stage 11, which is beneficial to the arrangement of the lamination stage 11 before lamination and the collective unloading after lamination.

Of course, during specific implementation, the above-mentioned method of driving each stacking stage 11 by the second driving part can be implemented by using existing technical means. For example, the rack 14 can be arranged on one side of the moving slide rail 13. The second driving part includes The driving motors are arranged on each stacking table 11, and the drive of each driving motor is connected with a driving gear that can mesh with the rack 14, and by making the driving gear model different, the operation of each stacking table 11 is realized. The sliding speeds are different, so that each stacking table 11 can be driven separately and parked at different positions.

When the lamination equipment of this embodiment is specifically set up and laid out, each mover assembly can carry two pole pieces (the first pole piece 21 or the second pole piece 22), and be configured with six lamination stages 11, each A lamination robot assembly (that is, two lamination robots 12 for twelve lamination robots 12) is disposed at the lamination table 11, and two lamination stations 111 are provided on each lamination table 11 to Realize the design of split double-station stacking table.

Subsequently, the spacing between each lamination stage 11 (lamination robot assembly) is set to 1750mm, thereby achieving a design form in which each lamination stage 11 can be separated and stacked independently with a spacing of 1750mm during the lamination process. At the same time, through The cooperative arrangement of the transfer slide rail and the driving part allows each lamination table 11 after lamination to be combined and unloaded at the same time in the blanking area (set at the end of the moving slide rail 13 away from the lamination area) with a work station spacing of 175mm. .

Moreover, in the structural layout of the stacking device, two scrapping and patching mechanisms can be provided, corresponding to the first feeding mechanism 31 and the second feeding mechanism 32 respectively, to complete the corresponding pole pieces (the first pole piece 21 Or the scrap removal and patching operation of the second pole piece 22), during specific implementation, the scrap removal and patching robots, the waste material station 61 and the patching station 62 in the two scrapping and patching mechanisms can be used along the length Direction and position adjustment can also help improve the operating rhythm.

In this way, by using a four-axis robot to carry, correct and double-station stacking methods, and combining the above-mentioned structural layout (six stacking stations 11) scheme design, compared with the existing use of a pair of four-station manipulators and The lamination solution of the integrated eight-station lamination table can break through the limit of its 480ppm ultimate lamination efficiency and achieve 1000ppm lamination efficiency, which solves the problem of existing pick-and-place robot handling, CCD vision and UVW alignment platform positioning. etc., there is an efficiency bottleneck problem in the lamination solution using the eight-station lamination table 11.

When laminating, the first loading mechanism 31 and the second loading mechanism 32 receive the pole pieces (the first pole piece 21 and the second pole piece 22) transferred from the previous process in their respective loading areas 35. , and each mover assembly is connected to two pieces. After receiving the pieces, each mover assembly moves to the buffer area 36 through the magnetic levitation ring track 33. The five mover assemblies in the buffer area 36 are in the process of picking up the materials at the No. 6 material picking station 341 (from left to right, ①～⑥ are taken). A mover in the material station 341) forms a mover module. Each mover module carries twelve pole pieces. Each mover module advances one mover module, that is, the spacing of six mover components, giving all stacks The film robot 12 supplies films.

When the stacking robot 12 at No. 1 material picking station 341 has taken out the last two pole pieces of a mover module, the six mover components of the mover module move to the material receiving area to receive materials. After each mover module is fed in place, the stacking robot 12 uses the visual positioning parameters of the first CCD camera assembly 41 to adjust the attitude of the pole piece, complete the pole piece deviation correction and then pick up the piece, completing the dual-station pick-up in two times. , after the stacking robot 12 has taken out the sheets, it will be transported to the stacking stage 11 for alternate stacking of the positive and negative electrode sheets (the first pole sheet 21 and the second pole sheet 22).

If the pole piece NG occurs during the robot picking process, the stacking robot 12 stops, and the waste removal and patching robot 63 moves to the NG position with the help of the magnetic levitation track to carry out waste removal and patching. After the pole pieces in the pole groups of all lamination tables 11 reach the set value, the lamination robot 12 stops, and the lamination table 11 uses the moving slide rail 13 to translate and unload materials. During the unloading and moving process of the lamination table, all the lamination tables 11 are merged and moved to the unloading area together with a distance of 175mm between work stations. After the unloading is completed, the lamination table 11 returns according to the original trajectory and is separated during the movement. Return to their respective lamination positions and keep the spacing at 1750mm, and then proceed to laminate the new pole group.

It should be noted that during the scrapping and patching process, the scrapping and patching robot 63 needs to first determine whether there is a patch in the patching station 62. If there is a pole piece, it will directly move to the NG position to perform the scraping and patching operation. If If there is no pole piece, the scrap removal and patching robot 63 moves to the pole piece loading area 35, and directly takes two pole pieces and places them on the patching station 62. After taking out the pieces, the scrap removal and patching robot 63 moves to the NG position, takes out the NG pieces and places them on the scrap station 61, and then places the qualified pole pieces on the patching station 62 at the pole piece NG, and the patching is completed. .

The stacking equipment of this embodiment, based on the grasping flexibility of the stacking robot component and the cooperation of the detection part that can position the first pole piece 21 or the second pole piece 22, can achieve extremely high performance on the basis of having the handling function. Compared with the existing technology that uses a robot and a UVW alignment platform to cooperate with the correction and positioning function, the chip correction and positioning function greatly reduces the width of the stacked segments, thereby reserving enough space for the transfer of the pole pieces. Combined with the first The loading mechanism 31 and the second loading mechanism 32 are both used in conjunction with a magnetic suspension conveyor line, which helps to improve the pole piece transfer efficiency;

At the same time, the design of the lamination robot assembly plus the split lamination table 11, compared with the existing design of the manipulator and the integrated lamination table 11, can prevent the lamination processes between the lamination tables 11 from interfering with each other, so as to Reduce the risk of falling pieces, reduce the complexity of scrapping and patching logic, and reduce the duration of scrapping and patching. It has better operability. Moreover, the position of the scrapping and patching robot 63 is adjustable in the length direction, which is also It can improve the efficiency of scrap removal and patching, thereby helping to break through the efficiency limitations of the existing lamination method.

The above descriptions are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in within the protection scope of this utility model.
