Description

Technical Field

[0001] The utility model relates to the technical field of electrode coating monitoring, in particular to electrode coating equipment and an electrode coating monitoring device. Background Art

[0002] The processing of lithium-ion battery pole pieces usually includes processes such as slurrying, coating, pressing, and die-cutting. In the battery pole piece coating process, the active material needs to be coated on both sides of the foil, and there are high requirements for the alignment of the coating edges on both sides. Generally, a visual monitoring system is used for quality inspection of the pole piece coating. Although the existing technology has high-precision monitoring quality, it does not have a corresponding marking mechanism to mark the defective part of the pole piece after detecting the defect. After the defect is found, a fairly long area needs to be carefully searched, which delays the subsequent processing process. Therefore, a pole piece coating equipment and a pole piece coating monitoring device are proposed to address the above problems. Utility Model Content

[0003] The purpose of the present invention is to provide a pole piece coating device and a pole piece coating monitoring device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pole piece coating device and a pole piece coating monitoring device, comprising a coating device, a monitoring bracket and a pole piece,

[0005] A monitoring bracket is installed on one side of the coating device, an inclined monitoring device is installed on the side of the monitoring bracket, and a pole piece is installed below the monitoring device;

[0006] The bottom of the monitoring bracket is fixedly connected to a symmetrically arranged synchronous moving mechanism, and the moving ends of the synchronous moving mechanism are fixedly connected to a marking mechanism;

[0007] The marking mechanism includes a mounting frame, a second motor and a threaded rod. The top of the mounting frame is fixedly connected to the synchronous moving mechanism. The second motor is installed inside the mounting frame. The end of the main shaft of the second motor is fixedly connected to the threaded rod. The outer side of the threaded rod is spirally connected to a threaded cylinder. The bottom of the threaded cylinder is fixedly connected to a buffer plate. The bottom of the buffer plate is fixedly connected to a sliding plate. The bottom of the sliding plate is fixedly connected to the mounting cylinder, and the interior of the mounting cylinder is spirally connected to a marking pen.

[0008] Furthermore, the buffer plate is made of a soft rubber plate.

[0009] Furthermore, a vertically arranged guide rod is fixedly connected to the interior of the installation frame, and the lower portion of the guide rod is slidably connected to the sliding plate and the installation cylinder.

[0010] The existing technology has high-precision monitoring quality, but after it detects a defect, there is no corresponding marking mechanism to mark the defective part of the electrode. After the defect is found, a fairly long area needs to be carefully searched, which delays the subsequent processing steps. When in use, an external power supply is required. Once the monitoring equipment detects a local defect in the electrode, the external controller can control the second motor to drive the threaded rod to rotate, and the threaded rod drives the threaded cylinder to move, so that the bottom of the marking pen and the surface of the electrode are marked under the action of the buffer plate, sliding plate and mounting cylinder. This setting can quickly find the defective area of the electrode and facilitate subsequent processing. In order to avoid excessive contact between the marking pen and the electrode, causing it to be punctured and damaged, the buffer plate provided plays a certain buffering role, effectively ensuring the quality of the electrode.

[0011] Furthermore, the synchronous moving mechanism includes a fixed frame, a first motor and a threaded shaft, the top of the fixed frame is fixedly connected to the monitoring equipment, the inside of the fixed frame is fixedly connected to the first motor, and the main shaft end of the first motor is fixedly connected to the threaded shaft, the other end of the threaded shaft is rotatably connected to the fixed frame, the outer side of the threaded shaft is spirally connected to a threaded sleeve, the outer side of the threaded sleeve is fixedly connected to a moving block, and the bottom of the moving block is fixedly connected to the marking mechanism.

[0012] Furthermore, the outer side of the movable block is slidably connected to the fixed frame.

[0013] Furthermore, the fixing frame is arranged horizontally.

[0014] During marking, since the pole piece is in a transport state, the first motor is started to drive the threaded shaft to rotate, and the threaded shaft drives the threaded sleeve and the moving block to move, thereby driving the marking mechanism to move. At this time, the marking mechanism can be ensured to have the same moving speed as the pole piece, thereby ensuring that the marking pen and the pole piece are relatively stationary, ensuring that the marking pen can stably perform the marking purpose and avoid scratching the pole piece.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When the utility model is in use, once the monitoring device detects that a local defect occurs in the electrode, the external controller can control the second motor to drive the threaded rod to rotate, and the threaded rod drives the threaded cylinder to move, so that the bottom of the marking pen and the surface of the electrode are marked under the action of the buffer plate, the sliding plate and the mounting cylinder. This arrangement can quickly find the defective area of the electrode and facilitate subsequent processing work;

[0017] In order to prevent the marking pen from excessively contacting the electrode and causing damage to it, the buffer plate provided plays a certain buffering role, effectively ensuring the quality of the electrode;

[0018] During marking, since the pole piece is in a transport state, the first motor is started to drive the threaded shaft to rotate, and the threaded shaft drives the threaded sleeve and the moving block to move, thereby driving the marking mechanism to move. At this time, the marking mechanism can be ensured to have the same moving speed as the pole piece, thereby ensuring that the marking pen and the pole piece are relatively stationary, ensuring that the marking pen can stably perform the marking purpose and avoiding scratches on the pole piece.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1 、 Figure 2 and Figure 4 , the utility model provides a technical solution:

[0026] A pole piece coating device and a pole piece coating monitoring device, comprising a coating device 1, a monitoring bracket 2 and a pole piece 3,

[0027] A monitoring bracket 2 is installed on one side of the coating device 1, and a tilted monitoring device 4 is installed on the side of the monitoring bracket 2. A pole piece 3 is installed below the monitoring device 4.

[0028] The bottom of the monitoring bracket 2 is fixedly connected to a symmetrically arranged synchronous moving mechanism 5, and the moving ends of the synchronous moving mechanism 5 are fixedly connected to a marking mechanism 6;

[0029] The above-mentioned marking mechanism 6 includes a mounting frame 601, a second motor 602 and a threaded rod 603. The top of the above-mentioned mounting frame 601 is fixedly connected to the synchronous moving mechanism 5. The second motor 602 is installed inside the above-mentioned mounting frame 601. The end of the main shaft of the above-mentioned second motor 602 is fixedly connected to the threaded rod 603. The outer side of the above-mentioned threaded rod 603 is spirally connected to a threaded cylinder 604. The bottom of the above-mentioned threaded cylinder 604 is fixedly connected to a buffer plate 605. The bottom of the above-mentioned buffer plate 605 is fixedly connected to a sliding plate 606. The bottom of the above-mentioned sliding plate 606 is fixedly connected to a mounting cylinder 607, and the inside of the mounting cylinder 607 is spirally connected to a marking pen 608.

[0030] The buffer plate 605 is made of a soft rubber plate.

[0031] A vertically arranged guide rod 609 is fixedly connected to the interior of the installation frame 601 , and the lower portion of the guide rod 609 is slidably connected to the sliding plate 606 and the installation cylinder 607 .

[0032] The existing technology has high-precision monitoring quality, but after it detects a defect, there is no corresponding marking mechanism to mark the defective part of the electrode. After the defect is found, a fairly long area needs to be carefully searched, which delays the subsequent processing process. When in use, an external power supply is connected. Once the monitoring device 4 detects that a local defect has occurred in the electrode, the external controller can control the second motor 602 to drive the threaded rod 603 to rotate, and the threaded rod 603 drives the threaded cylinder 604 to move, so that the bottom of the marking pen 608 and the surface of the electrode 3 are marked under the action of the buffer plate 605, the sliding plate 606 and the installation cylinder 607. This setting can quickly find the defective area of the electrode 3 and facilitate subsequent processing. In order to prevent the marking pen 608 from excessively contacting the electrode and causing it to be punctured and damaged, the buffer plate 605 provided plays a certain buffering role, effectively ensuring the quality of the electrode 3;

[0033] In this embodiment, when the sliding plate 606 moves, the guide rod 609 set on one side can ensure that the sliding plate 606 and the mounting tube 607 move up and down stably to prevent themselves from rotating. At the same time, once the marking pen 608 is damaged, it can be separated from the mounting tube 607 by rotating the marking pen 608, so that it can be replaced.

[0034] Example 2: This example is an improvement on Example 1. Figure 3Specifically, the synchronous moving mechanism 5 includes a fixed frame 501, a first motor 502 and a threaded shaft 503. The top of the fixed frame 501 is fixedly connected to the monitoring device 4. The inside of the fixed frame 501 is fixedly connected to the first motor 502, and the main shaft end of the first motor 502 is fixedly connected to the threaded shaft 503. The other end of the threaded shaft 503 is rotatably connected to the fixed frame 501. The outer side of the threaded shaft 503 is spirally connected to the threaded sleeve 504. The outer side of the threaded sleeve 504 is fixedly connected to a moving block 505. The bottom of the moving block 505 is fixedly connected to the marking mechanism 6.

[0035] The outer side of the movable block 505 is slidably connected to the fixed frame 501 .

[0036] The fixing frame 501 is arranged in a horizontal direction.

[0037] During marking, since the pole piece 3 is in a moving state, the first motor 502 is started to drive the threaded shaft 503 to rotate, and the threaded shaft 503 drives the threaded sleeve 504 and the moving block 505 to move, thereby driving the marking mechanism 6 to move. At this time, the marking mechanism 6 can be ensured to move at the same speed as the pole piece 3, thereby ensuring that the marking pen 608 and the pole piece 3 are relatively stationary, ensuring that the marking pen 608 is stable for marking purposes and avoiding scratches on the pole piece 3.

[0038] In this embodiment, when marking the electrode 3, the rotating roller below the electrode 3 can support the electrode 3, ensuring that the marking pen 608 can stably perform the marking work.

Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
