Description

Technical Field

[0001] The present invention relates to the technical field of battery processing, and particularly relates to a fire prevention device for soft-pack battery processing. Background Art

[0002] Currently, laser welding, ultrasonic welding, resistance welding and other processes are generally used for the series and parallel welding of soft-pack battery tabs. However, in the actual welding process, the problem of welding sparks has always been a major challenge faced by the industry. The high temperature and electric arc generated during welding are extremely likely to cause spark splashing. Once these sparks come into contact with the flammable electrolyte or other combustible materials inside the battery, it may trigger a fire or even an explosion accident. Such accidents will not only cause the scrapping of the soft-pack battery cells being processed, but also cause irreversible damage to the welding equipment, such as burning out precision welding heads, damaging temperature control systems and sensing devices, etc., greatly increasing the equipment maintenance and replacement costs. At the same time, the shutdown and maintenance after equipment damage will seriously affect the production progress, resulting in a decrease in production efficiency and a delay in order delivery, further pushing up the enterprise's operating costs. In addition, frequent fire accidents will also pose a serious threat to the personal safety of operators, increasing the enterprise's investment in safety production management. Summary of the Invention

Along the length direction of the working frame, a transmission component and a fire extinguishing component are sequentially arranged. On the transmission path of the transmission component, there is a carrier frame fixed on the working frame. The carrier frame corresponds to the soft-pack battery processing station and is connected with a monitoring component for monitoring the state of the soft-pack battery, so as to drive the transmission component to transfer the on-fire soft-pack battery into the fire extinguishing component after the soft-pack battery catches fire;

[0005] The transmission component includes a driving frame fixed on the working frame. On the driving frame, there are two parallel transmission shafts. Any one of the transmission shafts is driven by a driving motor controlled by the monitoring component. Transmission sprockets are arranged on both transmission shafts, and the two transmission sprockets are drivingly connected with a transmission chain for transmitting the soft-pack battery;

[0006] The fire extinguishing component includes a fire extinguishing cylinder corresponding to the return section of the transmission chain. The fire extinguishing cylinder is filled with a flame retardant material to prevent the soft-pack battery entering the fire extinguishing cylinder from continuing to burn.

[0007] As a further optimization of a fire prevention device for soft-pack battery processing according to the present invention: The transmission sprocket includes two sprockets provided on the transmission shaft, and the transmission chain includes two chains. The chain links on the two chains correspond one by one, and protective sheets are provided on the outer peripheries of two adjacent corresponding chain links to increase the contact area and flatness between the transmission chain and the soft-pack battery.

[0008] As a further optimization of a fire prevention device for soft-pack battery processing according to the present invention: There are two transmission sprockets and two transmission chains. The two transmission sprockets and transmission chains are respectively arranged on both sides of the transmission shaft corresponding to the drive frame to support both sides of the soft-pack battery.

Detailed Description of the Invention

[0022] In order to better understand the present invention, the content of the present invention will be further clarified below in conjunction with embodiments. However, the content of the present invention is not limited to the following embodiments.

[0023] As Figure 1As shown in the figure, a fire prevention device for soft-pack battery processing has a working rack 1 and a fire extinguishing component 6 to ensure the safety of soft-pack batteries during the processing. The working rack 1, as a support structure, is made of strong and durable materials and can withstand various pressures. The working rack 1 is designed in a U shape, and its concave part is used to place the fire extinguishing component 6 to ensure a rapid response to fire in case of an emergency. The fire extinguishing component 6 cooperates with the monitoring component 7 provided on the working rack 1 to quickly start extinguishing when a fire is detected. This reduces the damage to the equipment caused by a single soft-pack battery catching fire, reduces cost losses, and avoids the impact of equipment damage on the production cycle. The transmission component 3 is responsible for transporting the soft-pack battery from the processing position to the fire extinguishing component 6 to ensure the stability of the soft-pack battery during the transmission process. Advanced driving technology and precise transmission mechanisms are adopted to ensure the smooth and accurate transmission of the soft-pack battery. The monitoring component 7 includes, but is not limited to, image shooting, smoke detection sensors, and temperature detection sensors. At the same time, the detection component can also arbitrarily combine the above various monitoring methods to improve the monitoring accuracy and stability of the monitoring component 7. Specifically, the model, operation mode of the monitoring component 7, and the method of controlling the transmission component 3 should be understood as existing technologies.

[0024] As Figure 2 shown in the figure, the transmission component 3 includes a driving rack 306 provided on the working rack 1. Two transmission shafts 304 are provided on the driving rack 306, and any one of the transmission shafts 304 is driven to rotate forward and backward by a driving motor 305. Transmission sprockets 303 are arranged on both transmission shafts 304 to drive the transmission chain 302 tensioned by the transmission sprockets 303 on the two transmission shafts 304 to rotate in a cycle, improving the transmission efficiency and ensuring the stable transmission of the soft-pack battery. The transmission chain 302 is composed of two chains, and the chain links correspond to each other one by one and are arranged in parallel. The outer sides of the chain links are clamped with the two bottoms of a protective sheet 301. Specifically, the protective sheet 301 is arranged in an inverted U shape to protect the surface of the soft-pack battery, increase the friction of the battery during the transmission process, and reduce the probability of the battery slipping on the chain. There are two transmission sprockets 303 and two transmission chains 302, which are respectively arranged at both ends of the transmission shaft 304 inside the driving rack 306 to enhance the bearing capacity of the transmission component 3 and keep the soft-pack battery stable after moving to the vertical position of the work station. A pushing device is arranged between the two transmission chains 302 to stably push the soft-pack battery to an appropriate height for processing. On the inner sides of the driving rack 306 corresponding to the two chains, a limiting plate 307 is fixedly arranged to limit the relative position of the soft-pack battery during the moving process and ensure that the battery enters the work station in a corresponding posture, facilitating subsequent equipment to perform processing operations on the soft-pack battery. The driving motor 305 adopts a forward and reverse stepping motor, which has a simple structure, convenient control, and reliable operation, realizes the forward and reverse cyclic operation of the two transmission chains 302, performs stable two-way transmission of the soft-pack battery, improves the flexibility of the equipment, and makes the production process smooth. The equipment is provided with two transmission components 3 and two processing work stations, improving the transmission and processing efficiency of soft-pack batteries, enabling the equipment to process more soft-pack batteries simultaneously, and improving production efficiency and reducing costs.

[0025] A height difference is set between the transmission component 3 and the fire extinguishing component 6, so that the on-fire soft-pack battery falls towards the center of the fire extinguishing component 6 after detaching from the transmission component 3, reducing the probability of the on-fire soft-pack battery colliding with the edge of the fire extinguishing component 6 and improving the stability of the battery successfully falling into the fire extinguishing component 6 for fire extinguishing treatment. At the position where there is a height difference between the transmission component 3 and the fire extinguishing component 6, a guiding component 5 is provided to assist in guiding the on-fire soft-pack battery to the center of the fire extinguishing component 6 and improve the stability of the battery falling into the fire extinguishing component 6. On the side of the guiding component 5 facing the transmission component 3, an auxiliary plate 4 is provided to adapt to the gap between the driving frame 306 and the fire extinguishing component 6, assisting the on-fire soft-pack battery transmitted by the transmission component 3 to smoothly enter the fire extinguishing component 6 for fire extinguishing treatment, improving the reliability of the equipment and making the fire extinguishing process smooth. The guiding component 5 includes an inclined frame 501 fixedly provided on the working frame 1 and corresponding to the driving frame 306 and the fire extinguishing component 6. The extension line of the lower end corresponds to the center of the fire extinguishing component 6, guiding and transmitting the on-fire soft-pack battery, giving the battery a certain impact force, and enabling the on-fire battery soft pack to stably fall into the center of the fire extinguishing component 6 for fire extinguishing treatment. A plurality of rolling seats 502 are evenly arranged on the inclined surface of the inclined frame 501, reducing the friction force when the on-fire battery soft pack passes through the inclined frame 501, enabling the on-fire battery soft pack to quickly and stably pass through the inclined frame 501 and then be guided into the fire extinguishing component 6 for fire extinguishing treatment, improving the fire extinguishing efficiency and reducing the equipment wear and energy consumption. Specifically, the rolling seat 502 is arranged in a structure of a ball matching a ball groove seat. At both edges of the inclined frame 501 along the axial direction of the transmission shaft 304, limiting baffles 503 are provided to limit the range of the on-fire soft-pack battery passing through the inclined frame 501, preventing the battery from sliding out from the edge of the inclined frame 501, improving the guiding stability and ensuring the smooth progress of the fire extinguishing process.

[0026] The fire extinguishing component 6 includes a fire extinguishing cylinder 601 arranged in the concave part of the working frame 1. A certain depth of flame retardant material is contained in the fire extinguishing cylinder 601, and a traction handle 602 is fixedly arranged on the outer side surface of the fire extinguishing cylinder 601 to assist the operator in traction and relocation. After the on-fire battery soft pack enters the interior of the fire extinguishing cylinder 601, it quickly covers the battery to achieve the fire extinguishing operation, improving the fire extinguishing efficiency and ensuring the safety of the equipment. Universal wheels 603 are provided at the four corners of the bottom of the fire extinguishing cylinder 601, and a locking structure is arranged on the universal wheels 603 to position the fire extinguishing cylinder 601, enabling the fire extinguishing cylinder 601 to move and be positioned flexibly, improving the flexibility and adaptability of the equipment. A discharge pipe 604 is provided at the bottom of the fire extinguishing cylinder 601, and a valve is arranged on the discharge pipe 604, facilitating the operator to discharge the flame retardant material or lock it into the fire extinguishing cylinder 601 for use, improving the maintainability and usability of the equipment. The flame retardant material can include but is not limited to water, fine sand, and flame retardant foam particles, etc., which have different fire extinguishing effects and application ranges, and are selected and used according to the actual situation, improving the flexibility of the equipment and meeting the needs of different users.

[0027] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various deformations or modifications within the scope of the claims, which do not affect the essence of the present invention.
