Description

Technical Field

[0001] This disclosure relates to the field of battery manufacturing, and in particular to a coating assembly and coating equipment for battery electrode strips. Background Technology

[0002] Electrode coating is a key process in battery manufacturing. It involves uniformly coating a slurry with good stability, viscosity, and flowability onto the electrode, followed by drying to coat the electrode surface with an active layer. Existing coating methods typically involve an inclined feeding trough with a coating roller at the bottom. A belt-passing gap exists between the coating roller and the inclined feeding trough, allowing the electrode strip transported by the coating roller to pass through the gap. Slurry is then added to the bottom of the inclined feeding trough, flowing through the belt-passing gap to coat the electrode strip, thus completing the coating process. For example, prior art patent application CN202322970759.X – a coating equipment.

[0003] However, because the slurry is continuously added to the inclined feeding tank during the electrode coating process, the slurry will accumulate to a certain depth in the inclined feeding tank. The active particles in the slurry will settle at the bottom during accumulation, or even accumulate and stick to the inclined surface of the inclined feeding tank. As a result, the material in the slurry is not evenly dispersed, resulting in uneven distribution of slurry on the coated electrode strip and reducing the production yield of battery electrode strips. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a coating assembly and coating equipment for battery electrode strips that improves the dispersion effect of slurry in an inclined feeding tank so as to make the slurry coated on the electrode strips uniformly distributed.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] A coating assembly for a battery electrode strip includes: a first baffle plate, a second baffle plate, an inclined material plate, a first baffle plate, a second baffle plate, and a coating rotating roller. The inclined material plate is connected to the first baffle plate and the second baffle plate respectively. The first baffle plate and the second baffle plate are both mounted on the inclined material plate. The inclined material plate, the first baffle plate, and the second baffle plate together form an inclined material groove. The coating rotating roller is rotatably connected to the first baffle plate and the second baffle plate respectively. A strip passage gap communicating with the inclined material groove is formed between the coating rotating roller and the bottom of the inclined material plate.

[0007] The coating assembly also includes a mixing rack, an electrically driven translation block, a mixing rod, and a soft rubber block;

[0008] The mixing rack is connected to the first baffle and the second baffle respectively, and the mixing rack forms a first movable chute and a second movable chute;

[0009] The electric drive translation block is respectively disposed in the first movable slide groove and the second movable slide groove, so that the electric drive translation block is slidably connected to the stirring frame;

[0010] One end of the stirring rod is fixed to the electric drive translation block, and the other end of the stirring rod extends into the inclined trough;

[0011] One end of the soft rubber block is installed at the other end of the stirring rod, and the other end of the soft rubber block is slidably connected to the inclined material plate.

[0012] In one embodiment, the stirring rod includes a straight stirring rod portion and a stirring hook portion, one end of the straight stirring rod portion is fixed to the electric drive translation block, and one end of the stirring hook portion is fixedly connected to one end of the straight stirring rod portion.

[0013] In one embodiment, one side of the stirring hook is provided with an installation groove, and one end of the soft rubber block is provided with an installation protrusion, which is located in the installation groove.

[0014] In one embodiment, the stirring rod and the stirring hook are integrally formed.

[0015] In one embodiment, the soft rubber block is a one-piece injection molded structure.

[0016] In one embodiment, the tilt angle of the inclined plate is 30 degrees to 45 degrees.

[0017] In one embodiment, the tilt angle of the stirring hook is 145 degrees to 150 degrees.

[0018] In one embodiment, the coating assembly further includes a control assembly that is communicatively connected to both the electrically driven translation block and the coating rotary roller.

[0019] In one embodiment, the coating assembly further includes a slurry recovery tank, the feed end of which is located directly below the belt gap.

[0020] A coating apparatus comprising a coating assembly for battery electrode strips as described in any of the above embodiments.

[0021] Compared with the prior art, this disclosure has at least the following advantages:

[0022] 1. Since the inclined material plate, the first baffle plate and the second baffle plate together form an inclined material trough, the coating rotating roller is rotatably connected to the first baffle plate and the second baffle plate respectively. By driving the coating rotating roller to rotate, the electrode strip can be transported to the belt gap, and then the slurry is added into the inclined material trough that is connected to the belt gap, so that the slurry can be coated on the electrode strip to realize the coating function.

[0023] 2. Since the stirring rack is connected to the first baffle and the second baffle respectively, and the stirring rack forms the first moving chute and the second moving chute, the electric drive translation block is driven to slide in the first moving chute and the second moving chute to realize the translation function of the electric drive translation block. Since one end of the stirring rod is fixed to the electric drive translation block and the other end of the stirring rod extends into the inclined material trough, and one end of the soft block is installed on the other end of the stirring rod, the electric drive translation block can not only drive the soft block to slide and connect on the inclined material plate during the translation process, so as to scrape off the active particles adhering to the inclined material plate, but also stir the slurry in the inclined material trough during the translation process, so as to disperse the slurry in the inclined material trough evenly, thereby making the slurry on the coated electrode strip evenly distributed and improving the production yield of the battery electrode strip.

[0024] 3. By making the soft rubber block slide in connection with the inclined plate, the softness of the soft rubber block itself can reduce the wear problem caused by the rigid contact between the soft rubber block and the inclined plate, that is, reduce the wear of the inclined plate during use and extend the service life of the coating component.

The inclined plate is connected to the first and second baffle plates respectively. The first and second baffle plates are both mounted on the inclined plate, and the inclined plate, the first baffle plate, and the second baffle plate together form an inclined trough.

One end of the soft rubber block is installed on the other end of the stirring rod, and the other end of the soft rubber block is slidably connected to the inclined material plate.

[0037] Please see Figures 1 to 7 To better understand the coating assembly 10 of the battery electrode strip of this disclosure, the coating assembly 10 of the battery electrode strip is further explained below:

[0038] One embodiment of the coating assembly 10 for battery electrode strips includes a first baffle plate 100, a second baffle plate 200, an inclined plate 300, a first baffle plate 400, a second baffle plate 500, and a coating rotary roller 600. The inclined plate 300 is connected to the first baffle plate 100 and the second baffle plate 200 respectively. The first baffle plate 400 and the second baffle plate 500 are both mounted on the inclined plate 300. The inclined plate 300, the first baffle plate 400, and the second baffle plate 500 together form an inclined trough 302. The coating rotary roller 600 is rotatably connected to the first baffle plate 100 and the second baffle plate 200 respectively. A belt passage gap 304 communicating with the inclined trough 302 is formed between the coating rotary roller 600 and the bottom of the inclined plate 300. The coating assembly 10 also includes a stirring frame 700, an electrically driven translation block 800, a stirring rod 900, and a soft rubber block 1000. The mixing frame 700 is connected to the first baffle plate 100 and the second baffle plate 200 respectively, and the mixing frame 700 forms a first movable slide groove 702 and a second movable slide groove 704. An electrically driven translation block 800 is respectively disposed within the first movable slide groove 702 and the second movable slide groove 704, so that the electrically driven translation block 800 is slidably connected to the mixing frame 700. One end of the mixing rod 900 is fixed to the electrically driven translation block 800, and the other end of the mixing rod 900 extends into the inclined material trough 302. One end of the soft rubber block 1000 is installed on the other end of the mixing rod 900, and the other end of the soft rubber block 1000 is slidably connected to the inclined material plate 300.

[0039] In this embodiment, since the inclined material plate 300, the first baffle plate 400 and the second baffle plate 500 together form an inclined material trough 302, and the coating rotating roller 600 is rotatably connected to the first baffle plate 100 and the second baffle plate 200 respectively, by driving the coating rotating roller 600 to rotate, the electrode strip can be transported to the belt gap 304, and then the slurry is added into the inclined material trough 302 which is connected to the belt gap 304, so that the slurry can be coated on the electrode strip to realize the coating function.

[0040] Furthermore, since the mixing frame 700 is connected to the first baffle plate 100 and the second baffle plate 200 respectively, and the mixing frame 700 forms a first movable slide groove 702 and a second movable slide groove 704, the translation function of the electrically driven translation block 800 is realized by driving the electrically driven translation block 800 to slide within the first movable slide groove 702 and the second movable slide groove 704. Also, since one end of the mixing rod 900 is fixed to the electrically driven translation block 800, and the other end of the mixing rod 900 extends into the inclined material trough 302, and... One end of the software block is installed at the other end of the stirring rod 900, so that during the translation process, the electric drive translation block 800 can not only drive the soft rubber block 1000 to slide and connect on the inclined material plate 300, scraping off the active particles adhering to the inclined material plate 300, but also stir the slurry in the inclined material tank 302 during the translation process, so that the slurry in the inclined material tank 302 is evenly dispersed, thereby making the slurry on the coated electrode strip evenly distributed and improving the production yield of the battery electrode strip.

[0041] Furthermore, by making the soft rubber block 1000 slide in connection with the inclined plate 300, the softness of the soft rubber block 1000 itself can reduce the wear problem caused by the rigid contact between the soft rubber block 1000 and the inclined plate 300, that is, reduce the wear of the inclined plate 300 during use and extend the service life of the coating assembly 10.

[0042] like Figure 4 and Figure 5 As shown, in one embodiment, the stirring rod 900 includes a straight stirring rod portion 910 and a stirring hook portion 920. One end of the straight stirring rod portion 910 is fixed to the electric drive translation block 800, and one end of the stirring hook portion 920 is fixedly connected to one end of the straight stirring rod portion 910. It can be understood that the stirring hook portion 920 and the inclined material plate 300 are arranged parallel to each other. By driving the electric drive translation block 800, the straight stirring rod portion 910 is made parallel, causing the stirring hook portion 920 to stir the slurry in the inclined material tank 302 evenly, improving the dispersion effect of the slurry, thereby making the slurry distribution on the coated electrode strip uniform, and thus improving the production yield of the battery electrode strip.

[0043] like Figures 4 to 7As shown, in one embodiment, a mounting groove 922 is provided on one side of the stirring hook portion 920, and a mounting protrusion 1010 is provided at one end of the soft rubber block 1000, which is disposed within the mounting groove 922. It can be understood that by providing a mounting groove 922 on the stirring hook portion 920 and placing the mounting protrusion 1010 within the mounting groove 922, the soft rubber block 1000 can be stably fixed to the stirring hook portion 920, improving the connection stability between the soft rubber block 1000 and the stirring hook portion 920.

[0044] like Figure 5 As shown, in one embodiment, the stirring rod 910 and the stirring hook 920 are integrally formed. It is understood that this improves the structural stability of the stirring rod 900.

[0045] like Figure 6 and Figure 7 As shown, in one embodiment, the soft rubber block 1000 is a one-piece injection molded structure. It is understood that this improves the structural stability of the soft rubber block 1000.

[0046] like Figure 4 As shown, in one embodiment, the tilt angle of the inclined plate 300 is 30 degrees to 45 degrees. It can be understood that the tilt angle of the inclined plate 300 is 30 degrees to 45 degrees, which allows the slurry to flow into the belt gap 304 and be coated on the electrode belt.

[0047] like Figure 4 As shown, in one embodiment, the tilt angle of the stirring hook portion 920 is 145 degrees to 150 degrees. It should be noted that the tilt angle of the stirring hook portion 920 relative to the stirring rod portion 910 is 145 degrees to 150 degrees, so that the stirring hook portion 920 is parallel to the inclined material plate 300, thereby ensuring that the soft rubber block 1000 can slide on the inclined material plate 300.

[0048] like Figure 1 As shown, in one embodiment, the coating assembly 10 further includes a control assembly, which is communicatively connected to the electrically driven translation block 800 and the coating rotary roller 600, respectively. It is understood that by automating the control of the electrically driven translation block 800 and the coating rotary roller 600 through the control assembly, the automation level of the coating assembly 10 is improved, thereby increasing the coating efficiency of the coating assembly 10.

[0049] like Figure 1 As shown, in one embodiment, the coating assembly 10 also includes a slurry recovery tank (not shown), the inlet of which is located directly below the belt gap 304. It is understood that the slurry recovery tank allows for the recycling of any leaked slurry, preventing waste.

[0050] This disclosure also provides a coating apparatus, including a coating assembly for the battery electrode strip as described in any of the above embodiments.

[0051] In this embodiment, since the inclined material plate, the first baffle plate and the second baffle plate together form an inclined material trough, the coating rotating roller is rotatably connected to the first baffle plate and the second baffle plate respectively. By driving the coating rotating roller to rotate, the electrode strip can be transported to the belt gap, and then the slurry is added into the inclined material trough that is connected to the belt gap, so that the slurry can be coated on the electrode strip to realize the coating function.

[0052] Furthermore, since the stirring rack is connected to the first baffle and the second baffle respectively, and the stirring rack forms a first moving chute and a second moving chute, the electric drive translation block is driven to slide in the first moving chute and the second moving chute to realize the translation function of the electric drive translation block. Since one end of the stirring rod is fixed to the electric drive translation block and the other end of the stirring rod extends into the inclined material trough, and one end of the soft block is installed on the other end of the stirring rod, the electric drive translation block can not only drive the soft block to slide and connect on the inclined material plate during the translation process, so as to scrape off the active particles adhering to the inclined material plate, but also stir the slurry in the inclined material trough during the translation process, so as to disperse the slurry in the inclined material trough evenly, thereby making the slurry on the coated electrode strip evenly distributed and improving the production yield of the battery electrode strip.

[0053] Furthermore, by making the soft rubber block slide in connection with the inclined plate, the softness of the soft rubber block itself can reduce the wear problem caused by the rigid contact between the soft rubber block and the inclined plate, that is, reduce the wear of the inclined plate during use and extend the service life of the coating equipment.

[0054] Compared with the prior art, this disclosure has at least the following advantages:

[0055] 1. Since the inclined material plate, the first baffle plate and the second baffle plate together form an inclined material trough, the coating rotating roller is rotatably connected to the first baffle plate and the second baffle plate respectively. By driving the coating rotating roller to rotate, the electrode strip can be transported to the belt gap, and then the slurry is added into the inclined material trough that is connected to the belt gap, so that the slurry can be coated on the electrode strip to realize the coating function.

[0056] 2. Since the stirring rack is connected to the first baffle and the second baffle respectively, and the stirring rack forms the first moving chute and the second moving chute, the electric drive translation block is driven to slide in the first moving chute and the second moving chute to realize the translation function of the electric drive translation block. Since one end of the stirring rod is fixed to the electric drive translation block and the other end of the stirring rod extends into the inclined material trough, and one end of the soft block is installed on the other end of the stirring rod, the electric drive translation block can not only drive the soft block to slide and connect on the inclined material plate during the translation process, so as to scrape off the active particles adhering to the inclined material plate, but also stir the slurry in the inclined material trough during the translation process, so as to disperse the slurry in the inclined material trough evenly, thereby making the slurry on the coated electrode strip evenly distributed and improving the production yield of the battery electrode strip.

[0057] 3. By making the soft rubber block slide in connection with the inclined plate, the softness of the soft rubber block itself can reduce the wear problem caused by the rigid contact between the soft rubber block and the inclined plate, that is, reduce the wear of the inclined plate during use and extend the service life of the coating component.

[0058] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
