Description

Technical Field

[0001] This utility model relates to the field of battery cover manufacturing technology, and more specifically, to a burr removal device for battery pack cover manufacturing. Background Technology

[0002] Battery packs can be connected in series or in parallel. Parallel battery packs require each battery to have the same voltage, and the output voltage is equal to the voltage of one battery. Parallel battery packs can provide a stronger current. Series battery packs have fewer requirements, but the cover of the battery pack needs to have its surface burrs removed during processing.

[0003] Patent application CN2023201635726 discloses a burr removal device for battery pack cover production, including a polishing machine, an inlet roller, and a conveyor belt, as well as a pre-cleaning mechanism. The pre-cleaning mechanism consists of a U-shaped frame, a support plate, a vibrating motor, a connecting plate, an inclined shovel, and a strip brush. The inlet of the polishing machine is equipped with a conveyor belt for feeding the battery pack cover material into the polishing machine for polishing and deburring. An inlet roller is rotatably connected inside the polishing machine above the conveyor belt to cooperate with the conveyor belt in feeding the battery pack cover material into the polishing machine for polishing and deburring. The pre-cleaning mechanism is set at the polishing machine outside the conveyor belt. The pre-cleaning mechanism at the polishing machine allows the surface stains of the battery pack cover material entering the polishing machine to be pre-treated, so that the stain-removed battery pack cover material can be directly fed into the polishing machine for burr removal, thereby improving the polishing efficiency of the battery pack cover material at the polishing machine.

[0004] This structure improves the deburring effect by setting a cleaning mechanism in front of the battery cover polishing machine to scrape off the dust on the top of the battery cover. However, different specifications of battery covers may have protrusions on the top, which makes it impossible for the scraper to fit against the top of the battery cover, resulting in poor scraping effect and affecting subsequent polishing operations. At the same time, removing dust is not convenient for cleaning, affecting the working environment. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figures 1-5In this utility model, a burr removal device for battery pack cover production includes a polishing machine body 1 and a grinding component and a conveyor belt installed inside it. The grinding component is located at the top of the conveyor belt. A mounting frame 2 is connected to the right side of the polishing machine body 1. A movable plate 3 is slidably connected to the mounting frame 2. A movable frame 4 is slidably connected to the bottom of the movable plate 3. Two electric push rods 5 are fixedly installed on the mounting frame 2. The bottom end of the electric push rod 5 is installed on the top of the movable plate 3. Scrapers 6 arranged at equal intervals are slidably connected to the bottom of the movable frame 4. A spring 7 is fixedly connected to the top of the scraper 6. The top end of the spring 7 is connected to the bottom of the movable plate 3. An auxiliary component 8 is provided inside the polishing machine body 1. The polishing machine body 1 is equipped with a grinding head and a transmission system for driving the grinding head.

[0025] The auxiliary component 8 includes a collection cylinder 801, which is slidably connected inside the polishing machine body 1. A small push rod 802 is fixedly connected to the inner wall of the polishing machine body 1. The bottom end of the small push rod 802 is installed on the top of the collection cylinder 801. Air ducts 803 arranged at equal intervals are installed at the bottom of the collection cylinder 801. The front of the collection cylinder 801 extends through and to the outside of the polishing machine body 1. The bottom end of the scraper 6 is bent.

[0026] The right side of the mounting frame 2 is connected to two guide rails 9. The movable plate 3 is slidably connected to the guide rails 9. The top of the movable frame 4 is fixedly installed with a vibration motor 11. The top of the movable frame 4 is connected to two shock-absorbing pads 12. The top of the shock-absorbing pads 12 is in contact with the bottom of the movable plate 3.

[0027] When deburring is required during battery cover production, the operator conveys the battery cover to the polishing machine body 1 via a conveyor belt. Before the battery cover enters the polishing machine body 1, it passes the bottom of the mounting frame 2. The electric push rod 5 on the mounting frame 2 is activated, and the electric push rod 5 presses down, causing the movable plate 3 to slide down along the guide rail 9. The movable frame 4, which is slidably connected to the bottom of the movable plate 3, moves down accordingly. The scrapers 6, which are equidistantly arranged and slidably connected to the bottom of the movable frame 4, come into contact with the top of the battery cover. The spring 7 at the top of the scraper 6 contracts, making the scraper 6 fit more closely to the top of the battery cover. As the conveyor belt conveys the battery cover, the scraper 6 removes dust, glue, and other impurities from the top of the battery cover. The combined use of the electric push rod 5 and the spring 7 can be used for battery covers of different specifications.

[0028] Afterwards, the battery pack cover enters the polishing machine body 1. At this time, the auxiliary component 8 starts to operate. The small push rod 802 pushes the collection cylinder 801 up and down to adjust its position as needed. Since the front of the collection cylinder 801 extends through and to the outside of the polishing machine body 1, and one end of the collection cylinder 801 can be connected to a filter or other dust removal components, the air ducts 803 arranged at equal intervals at the bottom of the collection cylinder 801 generate suction to collect impurities on the top of the battery pack cover. Then, the battery pack cover is polished inside the polishing machine body 1 through the transmission system and the grinding head, thereby completing the burr removal work of the battery pack cover. During the whole process, the vibration motor 11 on the top of the movable frame 4 can be started as needed. The vibration generated by the vibration motor 11 when it is working is transmitted to the scraper 6 through the movable frame 4, which can help the scraper 6 to better remove impurities. The shock-absorbing pad 12 on the top of the movable frame 4 can reduce the impact of the vibration motor 11 on the movable plate 3.

[0029] In this invention, the battery pack cover is conveyed to the polishing machine body 1 via a conveyor belt. Before entering, the electric push rod 5 of the mounting frame 2 presses down the movable plate 3, and the scraper 6 at the bottom of the movable frame 4 contacts the battery cover. The spring 7 ensures good contact of the scraper 6, which can handle battery covers of different specifications and reduce interference with subsequent polishing. After entering the polishing machine body 1, the small push rod 802 of the auxiliary component 8 adjusts the position of the collection cylinder 801. The air duct 803 collects impurities with the help of external equipment suction to avoid impurities affecting polishing. When the transmission system and the polishing head are polishing, the scraper 6 is pre-cleaned to make the polishing more uniform. The vibration motor 11 of the movable frame 4 assists the scraper 6 in cleaning, and the shock-absorbing pad 12 reduces the impact of the vibration motor 11 on the movable plate 3 to ensure polishing stability.

[0030] Please see Figure 2 and 4 The spring 7 is equipped with a limiting sleeve 10 inside, and the two ends of the limiting sleeve 10 are respectively connected to the bottom of the movable plate 3 and the top of the movable frame 4.

[0031] In this utility model, the limiting sleeve 10 can limit the scraper 6 and the spring 7, so that the scraper 6 is always inside the movable frame 4 and slides vertically, and ensures the normal extension and contraction of the spring 7.

[0032] Please see Figure 4 and 5 The outer side of the collection cylinder 801 is fixedly connected to a baffle plate 13, which is slidably connected to the polishing machine body 1.

[0033] In this utility model, there is a through groove on the front of the polishing machine body 1 for the collection cylinder 801 to move, and the baffle plate 13 covers the through groove to prevent the interior of the polishing machine body 1 from being exposed.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
