Description

A dust removal device and a battery adhesive application device

[0001] This application claims priority to the patent application filed on November 4, 2024, with application number 2024226753872 and entitled "A dust removal device and a battery adhesive device". Technical Field

[0002] This application relates to a dust removal device and a battery adhesive application device, belonging to the field of battery manufacturing. Background Technology

[0003] Due to the rapid development of the new energy vehicle market, the demand for lithium batteries (hereinafter referred to as "batteries") is also increasing, as are the requirements for their production efficiency and product quality. In the battery production process, adhesive application is a crucial step that has a vital impact on battery performance and stability. Chinese patent publication number "CN220272555U" discloses an adhesive application device. However, the dust removal component in this device simply blows dust away with airflow, only removing dust that has settled on the battery, but failing to effectively remove dust that is adhered to the battery. Summary of the Invention

[0004] This application provides a dust removal device and a battery adhesive application device, which solve the problems disclosed in the background art.

[0005] According to one aspect of this disclosure, a dust removal device is provided, including a dust collection device and a scraper / brusher. The dust collection part of the dust collection device and the scraper / brusher are retractably disposed on one side of a battery conveyor line. The dust collection part and the scraper / brusher face the adhesive side of the battery on the battery conveyor line and can extend and retract toward the battery conveyor line. The scraper / brusher is located upstream of the dust collection part.

[0006] The aforementioned dust removal device is arranged in a telescopic manner along the battery production line, consisting of a scraping / brushing device and a dust suction device. The scraping / brushing device scrapes / brushes the dust on the adhesive side of the battery, preventing the dust from sticking to the battery. The dust suction device removes the non-sticky dust, effectively removing dust that is stuck to the battery.

[0007] In some embodiments of this disclosure, the dust collection unit and the scraper / brush device are disposed on the same telescopic platform, and the vertical distance from the end of the scraper / brush device to the adhesive side is less than the vertical distance from the opening of the dust collection unit to the adhesive side.

[0008] Using the same telescopic platform to house the dust collection unit and the dust scraping / brushing device not only simplifies the device structure but also reduces costs.

[0009] In some embodiments of this disclosure, a sealing element is provided at the opening edge of the dust collection part, and a notch communicating with the inner cavity of the dust collection part is provided on the side of the sealing element facing the scraping / brushing device.

[0010] When the suction unit is attached to the adhesive side, a slightly sealed space is formed between the suction unit and the adhesive side by a sealing element. This not only ensures the suction effect within the space, but also prevents dust from falling back onto the battery from outside the space. In addition, a notch is provided to facilitate the removal of dust adhering to the scraper / brush device, ensuring the cleanliness of the scraper / brush device.

[0011] In some embodiments of this disclosure, the scraping / brushing device is a brush head, and the dust suction unit is a dust suction hood.

[0012] The dust scraping / brushing device uses a common brush head on the market, and the dust suction unit uses a common dust suction cover on the market, which makes it easy to purchase and replace parts in a timely manner after they are damaged, and also reduces costs.

[0013] According to another aspect of this disclosure, a battery adhesive applicator is provided, including a battery conveyor line, the aforementioned dust removal device, and an adhesive applicator box disposed on one side of the battery conveyor line, facing the adhesive applicator side and located downstream of the dust removal device.

[0014] The dust removal device used in the above-mentioned battery adhesive applicator can effectively remove dust adhering to the battery, greatly improving the dust removal effect and thus increasing the pass rate of adhesive application.

[0015] In some embodiments of this disclosure, a retractable abutment plate can be provided on the other side of the battery conveyor line facing the dust removal device and the other side of the battery conveyor line facing the adhesive box. The abutment plate can extend and retract toward the battery conveyor line.

[0016] The retractable abutment plate installed opposite the dust removal device allows both the abutment plate and the dust removal device to press against the battery during dust removal, effectively preventing the battery from moving around on the battery conveyor line and thus ensuring the dust removal effect. Similarly, the retractable abutment plate installed opposite the adhesive application box allows both the abutment plate and the adhesive application box to press against the battery during adhesive application, effectively preventing the battery from moving around on the battery conveyor line and thus ensuring the adhesive application effect.

[0017] In some embodiments of this disclosure, the abutment plate facing the dust removal device and the abutment plate facing the adhesive box are connected to form an abutment plate arranged along the length of the battery conveyor line.

[0018] By connecting all the support plates into a whole, it is possible to support the battery not only during dust removal and adhesive application, but also during transmission, ensuring stable and efficient battery transmission.

[0019] In some embodiments of this disclosure, an auxiliary roller for assisting battery delivery is rotatably mounted against the long plate.

[0020] By using an auxiliary roller to change the sliding friction between the battery and the long plate into rolling friction, the battery can move more smoothly.

[0021] The beneficial effects achieved by this application are as follows: 1. The dust removal device of this application includes a scraping / brushing device and a dust suction device, which are arranged in a telescopic manner along the battery production line. The scraping / brushing device scrapes / brushes the dust on the battery adhesive side, so that the dust does not stick to the battery. The dust suction device removes the non-adhesive dust, which can effectively remove the dust that sticks to the battery; 2. The dust removal device used in the battery adhesive device of this application can effectively remove the dust that sticks to the battery, which greatly improves the dust removal effect and thus improves the adhesive bonding qualification rate.

[0028] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0029] Unless otherwise stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this disclosure.

[0030] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0033] It should be noted that similar symbols and letters in the following figures represent similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0034] To address the problem of dust removal components in existing battery adhesive application devices, this disclosure proposes a dust removal device and a battery adhesive application device, specifically employing a method of scraping / brushing followed by vacuuming for dust removal.

[0035] Figure 1 is a schematic diagram of an embodiment of the dust removal device disclosed herein. The embodiment of Figure 1 is used in a battery adhesive applicator.

[0036] As shown in Figure 1, the dust removal device includes a dust collection device and a scraper / brush device. The dust collection part and the scraper / brush device are telescopically installed on one side of the battery conveyor line. The dust collection part and the scraper / brush device are directly facing the adhesive side of the battery on the battery conveyor line, and can extend and retract toward the battery conveyor line under the action of the telescopic structure. The scraper / brush device is located upstream of the dust collection part.

[0037] It should be noted that the battery conveyor line can use an existing conveyor line. In Figure 2, a conveyor belt 11 and a drive roller conveyor line are used. The battery that needs to be glued is placed on the conveyor belt 11, and the drive roller 9 rotates to drive the conveyor belt 11 to move, thereby moving the battery.

[0038] It should be noted that, in order to support the battery conveyor line, it is generally mounted on a bracket, as shown in Figures 2 and 3. The bracket includes a base plate 8, on which a through mounting groove 10 is formed along the length direction. A drive roller 9 is rotatably mounted inside the mounting groove 10. A conveyor belt 11 is fitted between the drive rollers 9. A motor 14 is mounted on the base plate 8. The output end of the motor 14 is connected to the drive rollers 9, thereby driving the drive rollers 9 to rotate. A support leg 12 is fixed at the bottom of the base plate 8, which supports the entire battery conveyor line.

[0039] It should be noted that the scraping / brushing device can be a brush head 1, and the vacuuming device can include a vacuum hood 3 and an air pump 4 connected to the vacuum hood 3. These components are common in the market, and can be purchased and replaced in time if damaged, which can also reduce costs.

[0040] It should be noted that the vacuuming device and the scraper / brush device can be directly mounted on the substrate 8 on one side of the battery delivery line. In some embodiments, in order to simplify the device structure and reduce costs, the vacuuming part and the scraper / brush device can be mounted on the same telescopic platform. In order to ensure that both the scraper / brush device and the vacuuming part can act on the adhesive side of the battery, it is necessary to ensure that the vertical distance from the end of the scraper / brush device to the adhesive side is less than the vertical distance from the opening of the vacuuming part to the adhesive side. Specifically, the end of the brush head 1 is closer to the battery than the vacuum cover 3.

[0041] As shown in Figure 2, a first mounting plate 6 is fixed to the top of the substrate 8 on one side of the battery delivery line. An electric push rod 5 is installed on the side of the first mounting plate 6 away from the battery delivery line. The telescopic end of the electric push rod 5 passes through the first mounting plate 6 and is fixed to a second mounting plate 7. The dust hood 3 and the brush head 1 are both fixed to the side of the second mounting plate 7 facing the battery delivery line. The dust hood 3 and the brush head 1 are driven to move by the electric push rod 5. An air pump 4 can be installed on the other side of the second mounting plate 7. Of course, if the connecting pipe between the air pump 4 and the dust hood 3 is long enough, the air pump 4 can also be installed on the first mounting plate 6 or the substrate 8.

[0042] As shown in Figures 1 and 3, it should be noted that, in order to further ensure the dust removal effect, in some embodiments, a sealing element is installed at the opening edge of the dust suction part, and the side of the sealing element facing the scraping / brushing device is provided with a notch that communicates with the inner cavity of the dust suction part; specifically, a sealing ring 2 is glued to the opening end of the dust suction hood 3, and the notch can be recessed to form it, or a notch can be directly opened on the sealing ring 2.

[0043] When the suction part is attached to the adhesive side, the sealing ring 2 creates a slightly sealed space between the suction cover 3 and the adhesive side. This not only ensures the suction effect within the space but also prevents dust from falling onto the battery again from outside the space. The notch facilitates the suction transfer to remove dust adhering to the brush head 1, ensuring the cleanliness of the brush head 1.

[0044] When the battery is conveyed on the battery conveyor line, the electric push rod 5 pushes the dust cover 3 and the brush head 1 against the adhesive side of the battery. The brush head 1 scrapes / brushes the dust on the adhesive side of the battery, so that the dust does not stick to the battery. The dust is then sucked away by the vacuuming device, which can effectively remove the dust that sticks to the battery.

[0045] Figure 3 is a schematic diagram of an embodiment of the battery adhesive applicator disclosed herein, including a battery conveyor line, the aforementioned dust removal device, and an adhesive applicator box 13 installed on one side of the battery conveyor line, facing the adhesive applicator side and located downstream of the dust removal device.

[0046] The dust removal device used in the battery adhesive applicator can effectively remove dust adhering to the battery, greatly improving the dust removal effect and thus increasing the pass rate of adhesive application.

[0047] It should be noted that the adhesive application box 13 is an existing device and will not be described in detail here. The adhesive application box 13 is installed on the same side as the dust removal device, specifically on the top of the substrate 8 on the same side as the battery delivery line.

[0048] It should be noted that, in order to ensure the dust removal and adhesive application effects, in some embodiments, a retractable abutment plate can be installed on the other side of the battery conveyor line facing the dust removal device and on the other side of the battery conveyor line facing the adhesive application box 13. The abutment plate can extend and retract toward the battery conveyor line through a telescopic structure.

[0049] It should be noted that the mounting structure of the abutment plate can be the same as that of the second mounting plate 7, and the extension and retraction of the abutment plate can be achieved by the electric push rod 5.

[0050] The retractable abutment plate installed opposite the dust removal device allows the abutment plate and the dust removal device to jointly abut against the battery during dust removal, effectively preventing the battery from moving around on the battery conveyor line and thus ensuring the dust removal effect. The retractable abutment plate installed opposite the adhesive application box 13 allows the abutment plate and the adhesive application box 13 to jointly abut against the battery during adhesive application, effectively preventing the battery from moving around on the battery conveyor line and thus ensuring the adhesive application effect.

[0051] It should be noted that in some embodiments, the abutment plate facing the dust removal device and the abutment plate facing the adhesive box 13 are connected to form an abutment plate 15 installed along the length of the battery conveyor line, as shown in Figures 3 and 4.

[0052] The mounting structure of the abutment plate 15 can be similar to that of the second mounting plate 7, the only difference being that the abutment plate 15 requires multiple parallel electric push rods 5 to push it. The abutment plate 15 not only provides support for the battery during dust removal and adhesive application, but also during transmission, ensuring stable and efficient battery transfer.

[0053] It should be noted that in some embodiments, an auxiliary roller 17 for assisting battery transport is rotatably mounted on the abutting plate 15. The auxiliary roller 17 transforms the sliding friction between the battery and the abutting plate 15 into rolling friction, which can make the battery move more smoothly.

[0054] As shown in Figure 4, a frame 16 along the length direction can be installed on the side of the long plate 15 facing the battery conveyor line. An auxiliary roller 17 is rotatably installed inside the frame 16. The auxiliary roller 17 changes the sliding friction between the battery and the long plate 15 into rolling friction, making the battery move more smoothly.

[0055] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
