Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, and particularly relates to a sheet material collecting device for a sheet material collecting mechanism and a sheet material collecting device. Background Art

[0002] With the rapid development of the lithium-ion battery industry, the requirements for the production efficiency and quality of battery electrodes are increasing day by day. In the manufacturing process of lithium-ion batteries, it is inevitable to use a flexible die-cutting machine and an electrode collecting machine. The flexible die-cutting machine is a device used for the die-cutting process in the production of lithium-ion battery electrodes, and the electrode collecting machine is a device used for neatly storing the electrodes with consistent specifications formed after die-cutting. Among them, the sheet material collecting mechanism, as the core component of the electrode collecting device, its performance directly affects the sorting efficiency and finished product quality of the electrodes. The usual application scenario is that after die-cutting, the electrodes are picked up by a manipulator and stacked. Since the height of the stacked electrodes gradually increases, if the positioning of the sheet material collecting mechanism is inaccurate, the newly stacked electrodes will be inconsistent with the original stacked sheet layer, and then the edges of the electrodes may be damaged by the surrounding contacting objects, thus affecting the yield of the electrodes and the subsequent stacking of the positive and negative electrodes and diaphragms of the battery cells.

[0003] The design of the sheet material collecting mechanism in the existing electrode collecting device mostly adopts a four-bar fixed layout, that is, four sheet material collecting rods are installed on the fixed frame one by one through fasteners such as screws. This design is unable to cope with diverse production requirements, mainly reflected in:

[0004] 1. Low adjustment efficiency: In a flexible production line, whenever it is necessary to adjust to adapt to the production of electrodes of different sizes, the operator needs to adjust the position of each sheet material collecting rod one by one. This process not only takes time and effort, but also greatly reduces the flexibility and response speed of the production line.

[0005] 2. Difficulty in ensuring adjustment accuracy: Since the sheet material collecting rods are adjusted independently, it is difficult to ensure that the end faces of the two relatively sheet material collecting rods always remain precisely parallel during the adjustment process. This not only increases the adjustment difficulty, but also easily causes the electrodes to be damaged by uneven pressure during the sheet material collecting process, affecting the product yield.

[0006] In view of the above problems, there is an urgent need in the market for an innovative design of a sheet material collecting mechanism that can achieve rapid, precise and synchronous adjustment of the position of the sheet material collecting rods to flexibly meet the production requirements of electrodes of different sizes, and at the same time improve production efficiency and product quality.

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.

[0029] Embodiment 1:

[0030] See attached Figures 1 to 3 . The present embodiment provides a material-snapping mechanism of a sheet material receiving device, comprising at least one pair of material-snapping devices arranged opposite to each other, the pair of material-snapping devices arranged opposite to each other are used to align two opposite edges of the stored sheet material in one adjustment direction; the material-snapping devices appear in pairs, and the number of material-snapping devices can be one pair or two pairs. Preferably, the material-snapping mechanism comprises two pairs of material-snapping devices arranged opposite to each other, and the two pairs of material-snapping devices correspond to different adjustment directions of the sheet material, respectively. The material-snapping mechanism also comprises a material-snapping synchronous adjustment mechanism 5, which has at least two sections of threads with opposite rotation directions in the adjustment direction, and the material-snapping device and the material-snapping synchronous adjustment mechanism 5 are arranged in a transmission manner so that the material-snapping plates of a pair of material-snapping devices are synchronously approached or moved away when the threads rotate.

[0031] When the material-shooting mechanism needs to be adjusted, the material-shooting synchronous adjustment mechanism 5 is driven to rotate, so that at least two sections of threads with opposite rotation directions on the material-shooting synchronous adjustment mechanism 5 rotate, thereby driving a pair of material-shooting devices arranged for transmission therewith to move closer or farther synchronously, thereby realizing rapid adjustment of the material-shooting mechanism.

[0032] Embodiment 2:

[0033] See attached Figures 1 to 3 On the basis of Example 1, Figure 1 and Figure 2 As shown, the material-shooting mechanism includes a first material-shooting device 1, a second material-shooting device 2, a third material-shooting device 3, a fourth material-shooting device 4 and a material-shooting synchronization adjustment mechanism 5, wherein the first material-shooting device 1 and the third material-shooting device 3 are arranged opposite to each other, and the first material-shooting device 1 and the third material-shooting device 3 are used to adjust the sheet material in the first direction; the second material-shooting device 2 and the fourth material-shooting device 4 are arranged opposite to each other, and the second material-shooting device 2 and the fourth material-shooting device 4 are used to adjust the sheet material in the second direction, and the first direction is perpendicular to the second direction. The first direction and the second direction are as shown in FIG. Figure 1 As shown, in this embodiment, the x direction is represented as the first direction, and the y direction is represented as the second direction. The material shooting synchronization adjustment mechanism 5 and the first material shooting device 1, the second material shooting device 2, the third material shooting device 3, and the fourth material shooting device 4 are arranged for transmission. Specifically, the material shooting synchronization adjustment mechanism 5 includes a first adjustment component and a second adjustment component. The first adjustment component includes at least two sections of threads with opposite rotation directions arranged in the first direction to drive the material shooting plates of the first material shooting device 1 and the third material shooting device 3 to move closer or farther synchronously; the second adjustment component includes at least two sections of threads with opposite rotation directions arranged in the second direction to drive the material shooting plates of the second material shooting device 2 and the fourth material shooting device 4 to move closer or farther synchronously.

[0034] When producing sheets of different sizes, through the set sheet-pushing synchronization adjustment mechanism 5, the first sheet-pushing device 1, the second sheet-pushing device 2, the third sheet-pushing device 3, and the fourth sheet-pushing device 4 move along the direction of approaching or moving away from the sheet, so that the sheet-pushing mechanism can adapt to sheets of different specifications and models. Specifically, when the size of the produced sheet is relatively large, the first adjustment component drives the first sheet-pushing device 1 and the third sheet-pushing device 3, and the second adjustment component drives the second sheet-pushing device 2 and the fourth sheet-pushing device 4 to move synchronously along the direction away from the sheet; vice versa. In this embodiment, two groups of adjustment components are used to control the positions of the four sheet-pushing devices, enabling the sheet-pushing mechanism to achieve rapid die change and improve the die change efficiency.

[0035] Specifically, the first adjustment component and the first sheet-pushing device 1, the third sheet-pushing device 3 are connected by at least two threads with opposite helix directions arranged in the first direction; the second adjustment component and the second sheet-pushing device 2, the fourth sheet-pushing device 4 are connected by at least two threads with opposite helix directions arranged in the second direction.

[0036] As Figure 2 shown, the first adjustment component includes a first lead screw 51, and the first lead screw 51 is provided with two threads with opposite helix directions, which can be the first thread 511 and the third thread 512 respectively. The first thread 511, the third thread 512, and the first sheet-pushing device 1, the third sheet-pushing device 3 are in one-to-one correspondence. When the first lead screw 51 rotates under the action of an external force, the first lead screw 51 does not displace.

The second adjustment component includes a second lead screw 52, and the second lead screw 52 is provided with two threads with opposite helix directions, which can be the second thread 521 and the fourth thread 522 respectively. The second thread 521, the fourth thread 522, and the second sheet-pushing device 2, the fourth sheet-pushing device 4 are in one-to-one correspondence. When the second lead screw 52 rotates under the action of an external force, the second lead screw 52 does not displace. The second thread 521 drives the second sheet-pushing device 2 to move, and the fourth thread 522 drives the fourth sheet-pushing device 4 to move. Taking the first lead screw 51 as an example, the first thread 511 can be a right-handed thread, and the third thread 512 can be a left-handed thread. When the first lead screw 51 rotates forward, the first lead screw 51 does not displace. The first thread 511 drives the first sheet-pushing device 1 to move along the direction away from the sheet, and the third thread 512 drives the third sheet-pushing device 3 to also move along the direction away from the sheet, thereby realizing the synchronous movement away of the first sheet-pushing device 1 and the third sheet-pushing device 3.

[0037] In this embodiment, rockers can also be provided on the first lead screw 51 and the second lead screw 52 to facilitate the operation of the first lead screw 51 and the second lead screw 52.

[0038] Embodiment Three:

[0039] See the appendix Figures 1 to 3 Based on Embodiment Two, the structures of the first sheet feeding device 1, the second sheet feeding device 2, the third sheet feeding device 3, and the fourth sheet feeding device 4 can be the same. Specifically, as Figure 3 shown, the first sheet feeding device 1, the second sheet feeding device 2, the third sheet feeding device 3, and the fourth sheet feeding device 4 all include a sheet feeding assembly 11 and a support frame 12. The support frame 12 is used to fix and support the sheet feeding assembly 11, and the sheet feeding assembly 11 is used to adjust the sheet. Among them, the sheet feeding assembly 11 and the support frame 12 can be adjustably connected. For example, the sheet feeding assembly 11 is provided with a threaded hole, and the support frame 12 is provided with a countersunk hole extending along the direction close to or away from the sheet and having a relatively long length. The threaded hole and the countersunk hole are bolt-connected so that the sheet feeding assembly 11 and the support frame 12 are fixedly connected, but fine adjustment can also be made between the two.

[0040] Specifically, the sheet feeding assembly 11 includes a sheet feeding part 111 and a sheet feeding driving part 112. The sheet feeding driving part 112 is fixedly connected to the sheet feeding part 111, and the sheet feeding driving part 112 is used to drive the sheet feeding part 111 to reciprocate along the direction close to or away from the sheet. The sheet feeding driving part 112 can be an electric driving part. During the sheet feeding process, the electric driving part drives the sheet feeding plate to reciprocate along the direction close to and away from the sheet, so as to neatly store the sheet.

[0041] In this embodiment, the sheet feeding part 111 is a sheet feeding plate, and the top end of the sheet feeding plate is inclined, which is convenient for the sheet to fall smoothly into the action area of the sheet feeding mechanism during the falling process.

[0042] In this embodiment, a buffer layer is provided on the side of the sheet feeding part 111 close to the sheet. The buffer layer can be an elastic buffer film and can be used to protect the sheet during the sheet feeding process.

[0043] In this embodiment, as Figure 3 shown, the support frame 12 is provided with a positioning block 121. The positioning block 121 is used for positioning in the first direction and the second direction when the sheet feeding assembly 11 is installed. The setting of the positioning block 121 ensures that the end faces of the sheet feeding plates of the two relatively sheet feeding mechanisms always remain precisely parallel during the installation process of the sheet feeding assembly 11. Specifically, the positioning block 121 is an L-shaped structure, and the L-shaped positioning block 121 can be provided with a threaded hole and is threadedly connected to the support frame 12, so as to realize the fixation of the positioning block 121. Of course, the position of the positioning block 121 on the support frame 12 can also be adjusted according to the installation position of the sheet feeding assembly 11.
