Description
Technical Field
[0001] This utility model relates to the field of battery assembly equipment, and in particular to a tooling for feeding and preventing sticking of materials to an explosion-proof valve on a battery cover. Background Technology
[0002] With the rapid development of power battery technology, the assembly precision and reliability requirements for explosion-proof valves on battery covers, as key safety components, are increasing. In automated assembly processes, efficient feeding technology for explosion-proof valve plates has become a crucial factor restricting production efficiency and product quality. Traditional feeding fixtures often use a vibratory feeder combined with a robotic arm for adsorption. However, in practical applications, the following technical bottlenecks exist: due to the surface electrostatic adsorption effect and the thin design (typically 0.5mm to 1.0mm thick), explosion-proof valve plates are prone to interlayer adhesion during stacking. Existing technologies using a single vacuum adsorption method often result in the simultaneous adsorption of multiple plates or ineffective separation, leading to a feeding failure rate as high as 15% to 20%. Furthermore, conventional mounting slots use a single shape matching design, which cannot adapt to dimensional fluctuations (±0.05mm) caused by thermal expansion and contraction or processing errors. During high-speed feeding (cycle time ≥ 60pcs / min), the valve plate is prone to deflection or jamming, which directly affects the positioning accuracy of subsequent welding processes (required ≤ ±0.1mm); due to the lack of pressure control, the mechanical brushing device is prone to scratching the valve plate surface when removing foreign objects (roughness Ra value increases > 0.4μm), especially for valve plates with nickel plating (thickness 2-3μm), the surface damage rate can reach more than 8%.
[0003] To address the aforementioned issues, while existing technologies have proposed using elastic limiting block structures, the hardness of their buffer layer (Shore A70) may still cause valve plate indentation; alternatively, vibration-assisted separation can be introduced, but high-frequency vibration (>50Hz) can easily induce valve plate resonance displacement. Therefore, there is an urgent need to develop an anti-sticking material feeding device capable of precise separation, non-destructive clamping, and dynamic adjustment to meet the dual requirements of high yield (≥99.5%) and high-speed production (cycle time ≥120pcs / min) for intelligent manufacturing of new energy batteries. Utility Model Content
[0004] This utility model provides a tooling for feeding and preventing sticking of materials to an explosion-proof valve on a battery cover, which can solve the problem of the inability to orderly adsorb materials on the explosion-proof valve plates in the prior art.

[0006] A feeding fixture, wherein the feeding fixture is provided with an installation component, and the installation component is provided with multiple explosion-proof valve plates;
[0007] A brushing device is provided on the mounting component, and the brushing device is provided with a brush, which brushes the explosion-proof valve plate.
[0008] An adsorption device is provided with a suction nozzle, which adsorbs the explosion-proof valve plate, causing the explosion-proof valve plate to leave the mounting component.
[0009] Preferably, in this embodiment of the application, the mounting component includes a mounting groove, which is vertically arranged on the feeding fixture, and the shape of the transverse cross section of the mounting groove matches the shape of the explosion-proof valve plate, so that the explosion-proof valve plate is limited within the mounting groove.
[0010] Preferably, in this embodiment of the application, the brushing device includes a driving member, the driving member is disposed on both sides of the mounting groove, the driving member is provided with the brush member, and the brush member moves along the vertical direction of the mounting groove by the driving member.
[0011] Preferably, in this embodiment of the application, the driving component is configured as a driving track, the brush is disposed on the outer side of the driving track, and one side of the driving track abuts against the mounting groove, so that the brush is located in the mounting groove.
[0012] Preferably, in this embodiment of the application, a fixing adjustment member is provided in the mounting groove, and the fixing adjustment member includes:
[0013] A linear drive device is disposed on both sides of the mounting groove, with the output end of the linear drive device facing the mounting groove;

[0033] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0034] like Figures 1 to 4 As shown in the figure, the battery cover explosion-proof valve feeding and anti-sticking tooling provided in this embodiment of the utility model includes a feeding tooling 100 and an adsorption device 300. The feeding tooling 100 is provided with at least two mounting parts 110. Both mounting parts 110 are set vertically in the feeding tooling 100. The two mounting parts 110 are used to install the explosion-proof valve plate 120, which facilitates the storage of the explosion-proof valve plate 120.
[0035] In this embodiment of the application, each mounting component 110 can store at least 200 explosion-proof valve plates 120. The mounting component 110 is configured as a mounting groove 111, which is vertically arranged in the feeding fixture 100. The shape and structure of the transverse surface of the mounting groove 111 are the same as the shape and structure of the explosion-proof valve plate 120, so that the mounting groove 111 can limit the installation of the explosion-proof valve plate 120.
[0036] Preferably, in this embodiment, the mounting groove 111 can be independently set, which facilitates the detachment of the mounting groove 111 and its installation in the feeding fixture 100. In the feeding fixture 100, the mounting part 110 can also be set as an inclined groove with an inclination angle of about 3°-5° in the vertical direction. By setting the inclined groove position, on the one hand, it is convenient for the explosion-proof valve plate 120 to be evenly placed in the inclined groove, and on the other hand, it is convenient for the adsorption device 300 to pick up the explosion-proof valve plate 120 at the bottom of the inclined groove, thus avoiding the inability of the adsorption device 300 to adsorb the explosion-proof valve plate 120 in the inclined groove.
[0037] Preferably, in this embodiment, brushing devices 200 are provided on both sides of the outer wall of the mounting groove 111. Each brushing device 200 mainly includes a brush 210 and a driving device. The brush 210 is mounted on the driving device, which moves the brush 210 within the mounting groove 111 to facilitate brushing of the explosion-proof valve plate 120. The purpose of providing the brush 210 in this application is to separate two mutually bonded explosion-proof valve plates 120 when the suction device adsorbs them, allowing the suction device 300 to adsorb and transport only one explosion-proof valve plate 120 at a time.
[0038] To facilitate effective separation of the explosion-proof valve plate 120, the brushing device 200 is equipped with a driving component 220, which is a drive track located on both sides of the mounting groove 111. The operation of the brushing device 200 is achieved by rotating the drive track. Specifically:
[0039] In this embodiment, the drive track is driven to rotate by a motor, causing the track to rotate along the vertical direction of the mounting groove 111. A brush 210 is provided on the outer periphery of the drive track and is fixed on the drive track. When the drive track rotates on the mounting 110, the drive track will drive the brush 210 to move along the vertical direction of the mounting groove 111.
[0040] In this embodiment, one side of the drive track abuts against the mounting groove 111, so that the brush 210 is located in the mounting groove 111. At the same time, a gap of 0.1mm to 0.2mm is maintained between the drive track and the groove wall to avoid mechanical contact damage to the explosion-proof valve plate 120.
[0041] Meanwhile, in this embodiment, the brush 210 is configured as brush bristles, which can be used to brush apart the mutually adhered explosion-proof valve plates 120.
[0042] In this application, since the two explosion-proof valve plates 120 bonded together are relatively thin (typically between 0.5mm and 1.0mm), a single brush stroke of the brush 210 is insufficient to effectively separate the two explosion-proof valve plates 120 during the brushing process. To facilitate the effective separation of the explosion-proof valve plates 120, after the adsorption device 300 adsorbs and lifts the explosion-proof valve plates 120, the adsorption device 300 stops lifting, so that the explosion-proof valve plates 120 at the suction nozzle 310 are located in the mounting groove 111. At this time, the drive track is activated, and the drive track drives the brush 210 to continuously brush the explosion-proof valve plates 120 in a top-to-bottom direction for about 5 seconds, which facilitates the detachment of the top layer of explosion-proof valve plates 120 and achieves the separation of the explosion-proof valve plates 120 from each other.
[0043] As described above, due to the structural characteristics of its brush component 210, when the adsorption force between the explosion-proof valve pieces 120 is too large, the two explosion-proof valve pieces 120 cannot be effectively separated by the brush component 210. In order to avoid this situation, a fixing adjustment component 130 is provided in this embodiment. The main function of the fixing adjustment component 130 is to force the explosion-proof valve pieces 120 that cannot be effectively separated, so as to facilitate the movement and picking up of individual explosion-proof valve pieces 120.
[0044] Specifically:
[0045] In this embodiment, the fixed adjustment member 130 mainly includes a linear drive device 131 and a limiting device 132. There are two linear drive devices 131, which are respectively located on both sides of the mounting groove 111. The output end of the linear drive device 131 faces the mounting groove 111. The limiting device 132 is located on the output end of the linear drive device 131 and limits the explosion-proof valve plate 120 through the linear drive device 131. The linear drive device 131 is activated, driving the limiting device 132 to move laterally within the mounting groove 111. The limiting device 132 moves to the position of the explosion-proof valve plate 120 and limits the explosion-proof valve plate 120. At this time, the limiting device 132 will forcibly fix one or more explosion-proof valve plates 120 below. Since the two explosion-proof valve plates 120 are stuck together, when the limiting device 132 forcibly drives one explosion-proof valve plate 120 to be fixed, it can cooperate with the adsorption device 300 to forcibly separate the two stuck explosion-proof valve plates 120, so as to avoid the explosion-proof valve plates 120 from sticking together, thereby facilitating the adsorption device 300 to adsorb and transport the individual explosion-proof valve plates 120.
[0046] In this embodiment, the fixing adjustment member 130 is located at the upper opening of the mounting groove 111.
[0047] To facilitate the effective limiting and fixing of the explosion-proof valve plate 120 by the limiting device 132, in this embodiment, the limiting device 132 is configured as a limiting block, and the shape of the side of the limiting block facing the explosion-proof valve plate 120 corresponds to the shape of the side of the explosion-proof valve plate 120 facing the limiting device 132.
[0048] Preferably, in this embodiment, an elastic buffer layer 133 is provided on the contact surface of the limiting block facing the explosion-proof valve plate 120. The surface roughness Ra of the elastic buffer layer 133 is ≤1.6μm, and the Shore hardness of the elastic buffer layer 133 is A30~A50, with a thickness maintained at 0.3mm~0.5mm. The provision of the elastic buffer layer 133 not only effectively protects the surface of the explosion-proof valve plate 120 from damage, but also ensures a tight fit between the limiting block and the explosion-proof valve plate 120, improving the limiting effect. In addition, the elastic buffer layer 133 can also adapt to the dimensional fluctuations of the explosion-proof valve plate 120 caused by thermal expansion and contraction or processing errors to a certain extent, further improving the adaptability and stability of the tooling.
[0049] In some preferred embodiments of this utility model, the linear drive device 131 can be configured as a cylinder, an electric push rod, or a hydraulic cylinder, etc. These drive devices have advantages such as simple structure, reliable operation, and easy control, and can meet the tooling's requirement for rapid and accurate limiting of the explosion-proof valve plate 120. Simultaneously, a sensor can also be installed at the output end of the linear drive device 131 to monitor the position and status of the limiting device 132 in real time, ensuring the safe operation of the tooling.
[0050] It is worth mentioning that, in this embodiment, a photoelectric sensor array 400 is embedded in the side wall of the mounting groove 111. The photoelectric sensor array 400 is arranged along the vertical direction of the mounting groove 111. In order not to affect the use of the brush 210, in this embodiment, the photoelectric sensor array 400 and the brush 210 are arranged in pairs, with intervals between them. The detection accuracy of the photoelectric sensor array 400 is ±0.02mm. Under this structure, the photoelectric sensor array 400 not only has high-precision detection capability, but can also monitor the position and quantity of the explosion-proof valve plate 120 in the mounting groove 111 in real time, providing strong support for the automated control of the tooling. When the number of explosion-proof valve plates 120 in the mounting groove 111 is insufficient or the position is abnormal, the photoelectric sensor array 400 will promptly send a signal to remind the operator or automatic control system to take appropriate action, thereby ensuring the continuous and stable operation of the tooling.
[0051] Preferably, in this embodiment of the application, since there are two brushing devices 200, the two brushing devices 200 are set on both sides of the mounting member 110. In order to facilitate the photoelectric sensor to detect the explosion-proof valve plate 120, the photoelectric sensor is set on one side of the mounting member 110 and is located between the two brushing devices 200.
[0052] Preferably, in this embodiment of the application, the adsorption device 300 includes a vacuum adsorber, and the vacuum adsorber is provided with a suction nozzle 310.
[0053] In summary, the battery cover explosion-proof valve feeding and anti-sticking tooling provided by this utility model effectively solves the problems of disordered adsorption, easy adhesion, and easy damage of the explosion-proof valve plate 120 in the prior art through a series of innovative designs. It has the advantages of simple structure, convenient operation, strong adaptability, and high stability, and can be widely used in the field of intelligent manufacturing of new energy batteries, providing a strong guarantee for improving production efficiency and product quality.
[0054] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
