Abstract
Description
Technical Field
[0001] This application relates to the field of battery cover detection technology, and in particular to a debris collection device for detecting metal debris in battery covers. Background Technology
[0002] The lithium battery cover is a top cover in a power lithium battery assembly. Its structure mainly consists of a top cover plate, positive and negative terminals, an explosion-proof device, and a liquid injection hole. As a sealed part of the battery pack, the lithium battery cover primarily serves a sealing function to prevent internal liquid leakage. It also prevents external dust, moisture, air, metal debris, etc., from entering the battery, which could lead to a decline in battery quality or malfunction.
[0003] Before use, lithium battery covers need to be inspected. Among them, metal shavings detection is used to detect metal shavings left over from the manufacturing process. First, the battery cover is tapped to shake off the remaining metal shavings. Then, the number and particle size of the collected metal shavings are observed under a microscope. The battery cover is judged to be qualified according to the acceptance standards (e.g., 2 100-nanometer shavings are allowed, and 3 50-nanometer shavings are allowed).
[0004] Currently, the most common method for collecting debris is the tapping method. However, since there is no universal tooling equipment on the market to specify the tapping force and position, the measurement results have large deviations, poor consistency, and vary from person to person, making them unsuitable as an accurate basis for judgment. Utility Model Content
[0005] This application provides a debris collection device for detecting metal debris on battery cover plates, which solves the above-mentioned problems.
[0006] To achieve the above objectives, this application provides a debris collection device for detecting metal debris on a battery cover, comprising:
[0007] The bottom plate has two support platforms spaced apart on the top, which are used to support the two ends of the battery cover plate respectively.
[0008] A sliding assembly includes a guide member disposed on the base plate and extending vertically upward, and a sliding member slidably connected to the guide member, the sliding member being capable of sliding up and down along the guide member above the battery cover; and
[0009] The striking assembly includes a cylinder and a striking hammer, the cylinder being mounted on the sliding member, the piston rod of the cylinder facing downward and being fixedly connected to the striking hammer.
[0010] Optionally, the debris collection device includes three sliding components and three striking components. The three sets of sliding components are spaced apart on the base plate on one side of the battery cover, and the three striking components are respectively disposed on the three sliding components. The three striking components are used to strike the middle and both ends of the battery cover.
[0011] Optionally, limiting grooves are provided on the opposite inner sides of the top of both support platforms, and the limiting grooves are adapted to the ends of the battery cover.
[0012] Optionally, a recessed groove is provided on the base plate between the two support platforms, and a dust collection paper is placed in the groove to collect metal fragments that are knocked off the battery cover.
[0013] Optionally, the sliding assembly includes a linear guide rail, the guide is a slide rail, and the slider is a slider slidably connected to the slide rail.
[0014] Optionally, the hammer includes a connecting plate, a hammer rod, and a hammer head connected in sequence from top to bottom, and the connecting plate is connected to the piston rod of the cylinder.
[0015] Optionally, the hammerhead is made of rubber or silicone.
[0016] The beneficial effects of the debris collection device for detecting metal chips on battery covers provided in this application are as follows: Compared with the prior art, the debris collection device of this application uses a cylinder and a hammer mounted on the piston rod of the cylinder as the striking component for striking the battery cover. The striking component is mounted on the sliding member of the sliding component. In use, the two ends of the battery cover are supported on two support platforms on the base plate. The hammer is pressed against the battery cover by the gravity of the striking component and the sliding member. The cylinder is rapidly activated by compressed air, and while the hammer strikes the battery cover, it simultaneously lifts the cylinder and the sliding member upwards. Compared with manually striking the battery cover to collect metal chips, using this debris collection device is more efficient, and the striking force and striking position are more consistent, ensuring the consistency of the metal chip detection results for the battery cover.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0031] It should also be noted that in the embodiments of this application, the same reference numerals are used to represent the same component or part. For the same part in the embodiments of this application, the reference numerals may only be used to mark one part or component as an example. It should be understood that the reference numerals are also applicable to other identical parts or components.
[0032] As described in the background section, there are no universal tooling devices on the market to specify the striking force, striking position, etc., resulting in large deviations and poor consistency in measurement results. The measurement results also vary from person to person and cannot be used as an accurate basis for judgment.
[0033] To address the aforementioned problems, embodiments of this application provide a debris collection device for detecting metal debris on battery cover plates, such as... Figures 1-2 As shown, the debris collection device includes a base plate 100, a sliding assembly 200, and a striking assembly 300. Two support platforms 110 are spaced apart on the top of the base plate 100, supporting both ends of the battery cover 10. The sliding assembly 200 includes a guide member 210 extending vertically upwards from the base plate 100 and a sliding member 220 slidably connected to the guide member 210, allowing the sliding member 220 to slide up and down along the guide member 210 above the battery cover 10. The striking assembly 300 includes a cylinder 310 and a striking hammer 320. The cylinder 310 is mounted on the sliding member 220, with its piston rod pointing downwards and fixedly connected to the striking hammer 320.
[0034] In use, lift the striking component 300 upwards, support the two ends of the battery cover 10 on the two support platforms 110 on the base plate 100 respectively, lower the striking component 300, and the striking hammer 320 presses against the battery cover 10 under the gravity of the striking component 300 and the sliding member 220. The compressed air controls the cylinder 310 to move quickly. At the same time as the striking hammer 320 strikes the battery cover 10, the cylinder 310 and the sliding member 220 are lifted upwards.
[0035] In this embodiment, the debris collection device uses a cylinder 310 and a hammer 320 mounted on the piston rod of the cylinder 310 as a striking component 300 for striking the battery cover 10. The striking component 300 is mounted on the sliding member 220 of the sliding component 200. The striking action is completed by the up-and-down movement of the sliding member 220 and the extension and retraction of the cylinder 310, which accurately determines the striking position and force, improving measurement accuracy and ensuring the consistency of measurement results. Compared with manually striking the battery cover 10 to collect metal debris, using this debris collection device is more efficient, and the striking force and position are more consistent, ensuring the consistency of the metal debris detection results for the battery cover 10.
[0036] The base plate 100 can be made of bakelite, aluminum alloy, steel, etc., and there are no restrictions on its material.
[0037] Understandably, cylinder 310 requires an external air pipe, air pressure gauge, and external air source. The extension and retraction of cylinder 310 is achieved by switching the air circuit, and the air pressure is controlled by the air pressure gauge and valve to control the striking force of hammer 320.
[0038] In one embodiment, such as Figures 1-2 As shown, the debris collection device includes three sliding components 200 and three striking components 300. The three sets of sliding components 200 are spaced apart on the base plate 100 on one side of the battery cover 10 along its length. The three striking components 300 are respectively arranged on the three sliding components 200. The three striking components 300 are used to strike the middle and both ends of the battery cover 10, thereby achieving uniform striking of the battery cover 10.
[0039] In one embodiment, such as Figures 1-2 As shown, the top inner sides of the two support platforms 110 are provided with limiting grooves 111, which are adapted to the ends of the battery cover plate 10.
[0040] The limiting groove 111 improves the stability of the battery cover 10 on the support platform 110, ensuring that the battery cover 10 will not shift its position when it is hit.
[0041] Specifically, the height of the support platform 110 can be 10mm-50mm, the sinking depth of the limiting groove 111 can be 2mm-10mm, and it is used to position and fix the end of the battery cover 10. The four corners of the limiting groove 111 can be rounded.
[0042] In one embodiment, such as Figures 1-2 As shown, a recessed groove 101 is provided on the base plate 100 between the two support platforms 110. Dust collection paper (not shown in the figure) is placed in the groove 101. The dust collection paper is used to collect metal fragments that are knocked off the battery cover plate 10.
[0043] By setting up a settling tank 101 and dust collection paper, it is convenient to collect and transfer the metal shavings falling from the battery cover 10 located above the settling tank 101.
[0044] Specifically, the settling tank 101 should be lowered by 1mm-10mm. A heavy object can be used to press down on the perimeter of the dust collection paper to ensure that the dust collection paper does not shift.
[0045] In one embodiment, such as Figures 1-2 As shown, the sliding assembly 200 includes a linear guide rail, a guide member 210 which is a slide rail, and a slider 220 which is slidably connected to the slide rail. The linear guide rail has advantages such as high speed, low friction, low maintenance costs, and ease of installation and adjustment.
[0046] Understandably, the sliding component 200 can also adopt other structural forms, for example, the guide 210 is a smooth rod, and the sliding component 220 is a sliding sleeve that is slidably connected to the smooth rod.
[0047] In one embodiment, such as Figure 2-Figure 3 As shown, the hammer 320 includes a connecting plate 321, a hammer rod 322, and a hammer head 323 connected sequentially from top to bottom. The connecting plate 321 is connected to the piston rod of the cylinder 310. Specifically, the connecting plate 321 is provided with threaded holes, and the fixed connection between it and the piston rod of the cylinder 310 is completed by bolts. The connection is simple and reliable.
[0048] Preferably, the hammer head 323 is made of rubber or silicone. This design gives the hammer head 323 a certain degree of elasticity and hardness, preventing damage or injury to the battery cover 10 when struck.
[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0050] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
