Description
Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust collection device for detecting short circuits in batteries. Background Technology
[0002] Short-circuit testing is required during the battery manufacturing process. This test is performed before the battery is sealed to prevent potential short circuits during the earlier casting and welding processes, ensuring the safety of the battery in use. Before the short-circuit test, the battery needs to be cleaned to remove lead dust, lead shavings, and other contaminants, as these can interfere with the short-circuit test.
[0003] Based on this, it is necessary to use dust removal equipment to perform dust removal operations on the battery before short circuit testing. Patent publication number CN221926572U discloses a battery testing device. Before short circuit testing, the battery is flipped over and inverted. A dust extraction funnel is used to adsorb lead ash and other substances. The lead ash is cleaned by using its own gravity combined with negative pressure adsorption. The entire lead ash cleaning and short circuit testing are automated operations.
[0004] Automated dust removal operations are often insufficient to meet practical needs and make it difficult to monitor dust removal progress. Therefore, pre-dust removal is necessary before automated dust removal. Pre-dust removal involves manually arranging a certain number of batteries neatly on the production line. Workers then use handheld vacuum cleaners with flexible hoses to sequentially clean and remove the batteries. This pre-dust removal, followed by automated dust removal, ensures effective dust removal and effectively removes lead dust, lead shavings, and other contaminants.
[0005] However, it should be noted that when workers use handheld vacuum cleaners with flexible hoses to clean a certain number of batteries one by one, the cleaning time is long and the efficiency is low. In order to improve efficiency, the adsorption time may be shortened, resulting in poor dust removal effect. Summary of the Invention
[0006] This invention addresses the problem of low efficiency caused by workers manually using hand-held vacuum hoses to remove dust sequentially. It provides a vacuuming device for detecting short circuits in batteries. The device provides vacuuming power through a dust collection cabinet, which is connected to a suction hood via a hose. The suction hood is used to perform large-scale dust removal on neatly arranged batteries, thereby reducing labor intensity and improving dust removal efficiency.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] Dust suction device before detecting the short circuit of a storage battery, including a suspension bracket, a dust suction hood and a cleaning brush plate. The suspension bracket is suspended above the workshop. The dust suction hood is slidably arranged on the suspension bracket. The dust suction hood slides vertically up and down along the suspension bracket, facilitating approaching and moving away from the storage battery on the production line. An automatic telescopic part for driving the dust suction hood to slide is arranged on the suspension bracket, facilitating automatically controlling the up and down lifting of the dust suction hood. The automatic telescopic part is connected to the dust suction hood downward.
[0009] The dust suction hood includes a conical hood and a central pipe. A cleaning brush plate is horizontally slidably arranged below the conical hood, improving the cleaning effect on lead ash and lead chips. The conical hood is connected upward to the central pipe. The central pipe is located at the central position of the dust suction hood. The central pipe extends upward through the suspension bracket and is slidably connected to the suspension bracket. The central pipe is connected to a dust removal cabinet through a telescopic flexible air duct, facilitating providing suction force for the dust suction hood.
[0010] Furthermore, the cross section of the suspension bracket is in the shape of a Chinese character 'field'. A fixing ring is provided at the center of the suspension bracket. Reinforcing bent rods are arranged at the four corners of the suspension bracket. The corners of the suspension bracket are connected to the fixing ring through the reinforcing bent rods, improving the bearing capacity of the fixing ring.
[0011] The reinforcing bent rod includes a vertical rod and an inclined rod which are welded and fixed. The cross section of the combined vertical rod and inclined rod is in the shape of a '√'. The vertical rod is connected upward to the corner of the suspension bracket, and the inclined rod is connected upward to the fixing ring. The reinforcing bent rod can also enhance the structural strength of the entire suspension bracket.
[0012] Furthermore, the central pipe is arranged inside the fixing ring and slides vertically up and down along the fixing ring. The upper end of the central pipe extends upward above the suspension bracket, and the conical hood is arranged below the suspension bracket.
[0013] Furthermore, the automatic telescopic part is a cylinder. The number of the automatic telescopic parts is two, improving the stability of the up and down lifting of the dust suction hood. The automatic telescopic parts are symmetrically arranged on both sides of the suspension bracket, and the central pipe is arranged between the two automatic telescopic parts.
[0014] Furthermore, a limiting ring is also arranged on the central pipe. The limiting ring is arranged above the suspension bracket, and a compression spring is sleeved on the central pipe between the suspension bracket and the limiting ring. The compression spring is used to prevent the dust suction hood from falling downward due to the accidental failure of the cylinder.
[0015] Furthermore, the conical hood is a hollow frustum-shaped with a smaller upper part and a larger lower part. The upper end of the conical hood is connected to the central pipe, and the lower end of the conical hood is open. Guide rods are arranged on both sides of the lower end of the conical hood. A control component is slidably connected to each guide rod on each side. The control components extend into the conical hood, and the cleaning brush plate is bolted between the two control components. The cleaning brush plate is a long strip plate with bristles. The cleaning brush plate is arranged at the open part of the conical hood, facilitating cleaning the lead ash and lead chips above the storage battery.
[0016] The beneficial effects of this utility model through the above technical solution are:
[0017] This utility model features a rationally designed structure. A height-adjustable dust collection hood is positioned above the production line, its movement controlled by an automatic telescopic mechanism. The hood is connected to a dust collection cabinet via a telescopic flexible air duct. When lowered, the hood covers several neatly arranged batteries, and the dust collection cabinet provides suction to remove lead dust and lead shavings from the battery surfaces. When raised, the hood is moved away from the production line, providing ample space for workers to place and move the batteries.
[0018] This invention features a cleaning brush plate arranged at the open position at the lower end of the dust collection hood. The cleaning brush plate can be manually operated to move horizontally back and forth, using it to clean lead dust and lead shavings, making these substances easier to suck up. This increases dust removal efficiency and improves the cleaning effect, while also reducing the labor intensity of workers and better serving the short circuit detection process.

[0024] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:
[0025] like Figures 1-4As shown in the figure, the dust suction device before the short - circuit detection of the storage battery includes a suspension bracket 1, a dust suction hood 2 and a cleaning brush plate 3. The suspension bracket 1 is the installation carrier of the entire dust suction device, and the suspension bracket 1 has sufficient structural strength to support each component. The suspension bracket 1 is suspended above the workshop. Specifically, a suspension rod commonly used in building construction is used to install the suspension bracket 1, and the suspension bracket 1 is connected and fixed to the building in the workshop by the suspension rod, so as to ensure the suspended installation state of the suspension bracket 1. Below the suspension bracket 1 is the production line of the storage battery manufacturing.
[0026] The cross - section of the suspension bracket 1 is in the shape of a Chinese character 'tian'. The center of the suspension bracket 1 has a fixing ring 4. In order to improve the structural strength of the suspension bracket 1, strengthening bent bars 5 are arranged at the four corners of the suspension bracket 1. Furthermore, the number of the strengthening bent bars 5 is four. The corners of the suspension bracket 1 are connected to the fixing ring 4 through the strengthening bent bars 5, thereby improving the bearing capacity of the fixing ring 4.
[0027] In this embodiment, the strengthening bent bar 5 includes a vertical bar 51 and an inclined bar 52 which are welded and fixed. Both the vertical bar 51 and the inclined bar 52 are of angle steel structure or square pipe structure. The cross - section of the vertical bar 51 and the inclined bar 52 after connection and combination is in the shape of '√'. The vertical bar 51 is connected upward to the corner of the suspension bracket 1, and the inclined bar 52 is connected upward to the fixing ring 4. In this way, the four strengthening bent bars 5 are used to jointly support the fixing ring 4 to improve the bearing capacity of the fixing ring 4.
[0028] A dust suction hood 2 is slidably arranged on the suspension bracket 1. The dust suction hood 2 slides vertically up and down along the suspension bracket 1. The gravity of the entire dust suction hood 2 is borne by the fixing ring 4. The dust suction hood 2 includes a conical hood 21 and a central tube 22. The conical hood 21 is a hollow frustum with a smaller top and a larger bottom. The lower end of the conical hood 21 is open. Around the lower end of the conical hood 21, lamp bars are arranged, which can illuminate downward to facilitate observing the dust removal situation of the storage battery. The lamp bars are not shown in the figure. The conical hood 21 is connected upward to the central tube 22, that is, the upper end of the conical hood 21 is connected to the central tube 22, and the central tube 22 is located at the center of the dust suction hood 2.
[0029] When the dust suction hood 2 is installed on the suspension bracket 1, the central tube 22 extends upward through the suspension bracket 1 and is slidably connected to the suspension bracket 1. Specifically, the central tube 22 is arranged inside the fixing ring 4 and slides vertically up and down along the fixing ring 4, and the upper end of the central tube 22 extends upward above the suspension bracket 1. Furthermore, the conical hood 21 is arranged below the suspension bracket 1.
[0030] To drive the vacuum hood 2 to slide up and down, an automatic telescopic component 6 is installed on the suspension bracket 1 to drive the vacuum hood 2 to slide. The automatic telescopic component 6 is a cylinder, and there are two automatic telescopic components 6, symmetrically arranged on both sides of the suspension bracket 1, with a central tube 22 positioned between the two components. After the automatic telescopic components 6 are installed on the suspension bracket 1, they connect downwards to the vacuum hood 2. The simultaneous operation of both automatic telescopic components 6 can move the vacuum hood 2 up and down, or move it closer to or away from the production line.
[0031] Since the automatic telescopic component 6 uses a cylinder, which is driven by compressed air, a limit ring 7 is also provided on the central tube 22 to prevent the cylinder from failing unexpectedly during operation. The limit ring 7 is arranged above the suspension bracket 1, and a compression spring 8 is sleeved on the central tube 22 between the suspension bracket 1 and the limit ring 7. The compression spring 8 is used to support the dust cover 2, ensuring that the dust cover 2 moves upward and close to the suspension bracket 1, thereby preventing the dust cover 2 from falling unexpectedly.
[0032] Note: The upper end of the central tube 22 is connected to a dust collection cabinet via a telescopic flexible air duct, thus providing suction for the dust collection hood 2. The telescopic flexible air duct and the dust collection cabinet are not shown in the figure. The dust collection cabinet is an existing technology, which includes a cabinet body, an air inlet, an air outlet, and a high-suction fan and a non-woven filter screen arranged inside the cabinet. The operation of the dust collection cabinet can cause the gas containing lead ash and lead dust to pass through the dust collection hood 2 and the telescopic flexible air duct in sequence before entering the dust collection cabinet, thereby achieving the treatment of lead ash and lead dust.
[0033] The principle of this invention is as follows: Batteries from the previous workstation are transported to the current workstation. Several batteries are neatly arranged on the assembly line by hand. The cross-section of the arranged batteries must be smaller than the cross-section of the conical hood 21 to ensure that the dust collection hood 2 can cover the batteries. A control cylinder moves downwards, using two cylinders simultaneously to move the dust collection hood 2 down above the batteries. At the same time, the dust collection cabinet starts, and under the suction of the dust collection cabinet, combined with the dust collection hood 2, lead dust and lead shavings from the surface of several batteries can be removed in one go, improving dust removal efficiency. After dust removal, the cylinder moves upwards, causing the dust collection hood 2 to rise and move away from the batteries, providing space for personnel to move the batteries. Simultaneously, the dust collection cabinet stops operating. Finally, the dust-removed batteries are manually pushed to the next workstation, the short-circuit testing workstation.
[0034] To optimize the product structure and improve dust removal efficiency, a cleaning brush plate 3 is horizontally slidable below the conical cover 21. The cleaning brush plate 3 is used to clean the upper surface of the battery, ensuring thorough removal of lead dust and lead filings. Specifically, guide rods 9 are provided on both sides of the lower end of the conical cover 21. During installation, two fixing blocks 10 are provided on the conical cover 21 to mount the guide rods 9.
[0035] A control assembly 11 is slidably connected to the guide rod 9 on each side. The control assembly 11 includes a sliding seat 12 and a handheld plate 13. The sliding seat 12 is slidably connected to the guide rod 9 via a linear bearing. The handheld plate 13 is bolted to the top of the sliding seat 12. The handheld plate 13 is horizontally arranged. One end of the handheld plate 13 is a plate-shaped mounting section 131, and the other end is a handheld section 132 with a "U"-shaped cross-section. The control assembly 11 extends into the conical cover 21, that is, the mounting section 131 extends into the conical cover 21. An elongated hole 14 is provided on the conical cover 21. The mounting section 131 passes through the elongated hole 14 and extends into the conical cover 21 to prevent obstruction of the movement of the control assembly 11.
[0036] The cleaning brush plate 3 is bolted between the two control components 11. Specifically, the mounting section 131 of the handheld plate 13, which extends into the conical hood 21, is bolted and fixed to the cleaning brush plate. The cleaning brush plate 3 is a long strip with bristles, with the bristles facing downwards. The cleaning brush plate 3 is positioned at the opening of the conical hood 21. When the battery is covered under the dust collection hood 2 and the dust collection cabinet is started, the worker can move the handheld plate 13 to move the cleaning brush plate horizontally back and forth, thereby using the brush to clean the lead dust and lead shavings above the battery, making these substances easier to suck away and ensuring good dust removal effect.

Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
