Description

Technical Field

[0001] This application belongs to the field of laser processing technology, and more specifically, relates to a reversing device and laser processing equipment. Background Technology

[0002] In the manufacturing process of power lithium batteries, the steel casing is a key component of the battery system. The battery cell, consisting of the positive electrode, negative electrode, separator, and electrolyte, is housed within the steel casing. The steel casing not only secures the internal electrochemical system but also provides a crucial seal. During charging and discharging, a certain amount of gas is generated, creating pressure inside the casing. Therefore, the sealing and stability of the steel casing are critical to battery performance and safety.

[0003] However, in the process of installing lithium-ion battery cells into steel casings, there is a special condition where the steel casings on a parallel conveyor need to be transferred to a vertical conveyor. Currently, the common practice is to use a three-degree-of-freedom mechanism to accomplish this conversion, achieved by rotating the steel casing 90° between two stations. However, this three-degree-of-freedom mechanism has significant drawbacks: firstly, its cycle time is long, making it difficult to meet the needs of high-efficiency production; secondly, the hardware cost is high, increasing production costs and reducing the company's economic benefits. Therefore, existing technologies still need improvement in terms of efficiency and cost in the lithium-ion battery steel casing transfer process. Utility Model Content

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] Please see Figure 1 and Figure 2 The reversing device provided in the embodiments of this application will now be described. The reversing device provided in the embodiments of this application includes a mounting frame 1, a conveying assembly 2, and a reversing mechanism 3. The conveying assembly 2 is disposed on the mounting frame 1 and is used to convey workpieces. The reversing mechanism 3 is disposed on the mounting frame 1 and is used to change the incoming direction of the workpieces.

[0036] The reversing mechanism 3 includes an adsorption reversing component 31, which includes a guide side suction member 311 and a guide top suction member 312. The guide side suction member 311 is connected to the mounting frame 1, and the guide top suction member 312 is connected to the guide side suction member 311. The guide side suction member 311 is installed on the side of the conveying component 2, and the guide top suction member 312 is installed above the conveying component 2. The guide side suction member 311 and the guide top suction member 312 are used to attract workpieces to change the placement direction of the workpieces.

[0037] The workpiece in this application embodiment can be a lithium battery steel shell, cell, battery, or other workpiece to be processed that requires a change in placement orientation.

[0038] Mounting frame 1 is the basic framework of the entire reversing device, used to support and secure other components. Mounting frame 1 is made of robust metal materials, such as high-strength aluminum alloy or steel, to ensure the overall stability and durability of the device. The shape of mounting frame 1 can be designed according to the actual production space and the layout of the conveyor components 2, and is usually a rectangular frame structure with sufficient rigidity and support capacity.

[0039] The conveying assembly 2 is mounted on the mounting frame 1 and is used to convey workpieces. The conveying assembly 2 can be a common conveyor belt, conveyor roller, or other suitable conveying method.

[0040] The guide side suction member 311 is installed on the side of the conveying assembly 2 and is fixedly connected to the mounting bracket 1. The guide side suction member 311 can guide the workpiece to change direction by generating negative pressure to attract the side of the workpiece.

[0041] The top guide suction component 312 is mounted above the conveying assembly 2 and connected to the side guide suction component 311. The top guide suction component 312 can generate negative pressure to attract the top of the workpiece and works in conjunction with the side guide suction component 311 to change the placement direction of the workpiece.

[0042] When the workpiece is placed on the conveying assembly 2, its length direction is parallel to the conveying direction of the conveying assembly 2. When the conveying assembly 2 conveys the workpiece to the vicinity of the adsorption reversing assembly 31, the guide side suction member 311 attracts the workpiece, causing one end of the workpiece to face the guide side suction member 311. That is, the length direction of the workpiece is no longer parallel to the conveying assembly 2. As the conveying assembly 2 continues to convey the workpiece, when the workpiece approaches the guide top suction member 312, the guide top suction member 312 attracts the workpiece, correcting the workpiece angle so that the length direction of the workpiece is perpendicular to the conveying direction of the conveying assembly 2, thereby realizing the reversal of the workpiece. In this way, the placement angle of the workpiece can meet the requirements of the next process.

[0043] An outer cover may also be provided above the adsorption reversing component 31 in this embodiment of the application to prevent the workpiece from falling out of the conveying component 2 after reversing.

[0044] The commutation device in this application embodiment abandons the complex three-degree-of-freedom mechanism and adopts the relatively simple and efficient adsorption commutation component 31, which reduces the complexity of the mechanical structure and the number of parts, thereby reducing hardware costs and improving the economic benefits of enterprises.

[0045] Compared with traditional three-degree-of-freedom mechanisms, the cycle time is significantly shortened, production efficiency is significantly improved, and the needs of high-efficiency production are met. In addition, the reversing device of this application has a compact structure, reasonable layout, and small space occupation, which makes it easy to install and lay out in limited production sites, thereby improving the space utilization rate of production equipment.

[0046] The guide side suction component 311 includes a side mounting part and a side suction part. The side mounting part is connected to the mounting frame 1 and is mounted on the side of the conveying assembly 2. The side suction part is mounted on the side mounting part and is used to attract the workpiece to change the placement direction of the workpiece.

[0047] In this embodiment, the side mounting part can be a mounting plate, and the side suction part can be a negative pressure adsorption component, a permanent magnet, or an electromagnet. Using a permanent magnet can eliminate the hassle of wiring, and using a negative pressure adsorption component or an electromagnet can adjust the magnetic attraction force according to the material and weight of the workpiece.

[0048] The guide suction member 312 includes an upper mounting part and an upper suction part. The upper suction part is mounted on the upper mounting part and is used to attract the workpiece to change the placement direction of the workpiece. The upper mounting part is connected to the side mounting part and is disposed above the conveying assembly 2 to form a guide groove 313 for the workpiece to pass through with the conveying assembly 2. A guide slope is provided on the upper mounting part to facilitate the workpiece entering the guide groove 313.

[0049] In this embodiment, the upper mounting part can be a mounting plate, and the upper suction part can be a negative pressure adsorption component, a permanent magnet, or an electromagnet. Using a permanent magnet can eliminate the hassle of wiring, and using a negative pressure adsorption component or an electromagnet can adjust the magnetic attraction force according to the material and weight of the workpiece.

[0050] The reversing mechanism 3 also includes an air blowing assembly 32, which is mounted on the mounting bracket 1 and on the other side of the conveying assembly 2. The air blowing assembly 32 is used to blow the workpiece toward the side close to the guide side suction member 311.

[0051] The main function of the air blowing assembly 32 is to blow the workpiece towards the side closer to the guide side suction component 311 by air blowing when the workpiece enters the working range of the reversing mechanism 3, so that the workpiece can enter the working range of the adsorption reversing assembly 31 more accurately and improve the stability and success rate of reversing.

[0052] When the workpiece approaches the reversing mechanism 3, the air blowing assembly 32 is activated. The air blowing assembly 32 blows air onto the workpiece, directing it towards the side closer to the guide suction member 311. The direction and force of the air blowing can be adjusted according to the shape and weight of the workpiece to ensure that the workpiece can accurately enter the effective range of the adsorption reversing assembly 31.

[0053] The air blowing component 32 can specifically be a fan.

[0054] Preferably, the air blowing assembly 32 includes an air blowing component 321 and an adjustable mounting component 322. The adjustable mounting component 322 is mounted on the mounting bracket 1, and the air blowing component 321 is mounted on the adjustable mounting component 322. The air blowing component 321 is used to blow the workpiece toward the guide side suction component 311, and the adjustable mounting component 322 is used to adjust the angle between the air blowing direction of the air blowing component 321 and the length direction of the conveying assembly 2.

[0055] The air blowing component 321 can be a nozzle, which can be connected to an air pump to provide a stable airflow to the nozzle.

[0056] The adjustable mounting component 322 can specifically be a rotary motor, which is mounted on the mounting bracket 1 and located on the other side of the conveying assembly 2. An air blowing component 321 is mounted on the rotary motor. The rotary motor adjusts the angle between the air blowing direction of the air blowing component 321 and the length direction of the conveying assembly 2 by rotating the air blowing component 321. The adjustable mounting component 322 may also include a mounting plate and a mounting threaded component. The air blowing component 321 is mounted on the mounting plate, which has a through hole for the mounting threaded component to pass through. The mounting bracket 1 has a threaded hole, and the mounting threaded component passes through the through hole in the mounting plate and is threadedly connected to the threaded hole in the mounting bracket 1 to fix the mounting plate. Loosening the mounting threaded component allows the mounting plate to be rotated, thereby adjusting the angle between the air blowing direction of the air blowing component 321 and the length direction of the conveying assembly 2.

[0057] The air blowing assembly 32 also includes a quick connector 323 for connecting the air blowing element 321 and an external air supply device.

[0058] The quick connector 323 uses a standard pneumatic quick connector, featuring rapid connection and disconnection. Its connection method is simple: just insert the air hose of the external air supply device into the interface of the quick connector 323, and the quick connector 323 connects to the air blowing element 321 to establish airflow. The quick connector 323 is typically made of metal or high-strength plastic, offering excellent sealing and durability. Through the quick connector 323, the air blowing element 321 can be easily connected to different external air supply devices, improving the flexibility and adaptability of the device.

[0059] The air blowing assembly 32 also includes a flow regulator 324, which is connected to the air blowing assembly 321 to regulate the air flow rate of the air blowing assembly 321.

[0060] The flow regulator 324 can adjust the air flow according to the shape and weight of the workpiece to ensure that the direction and force of the blowing are appropriate, so that the workpiece can accurately enter the effective range of the adsorption reversing component 31.

[0061] The flow regulator 324 can be either a manual or automatic regulating valve. Manual regulating valves are adjusted via knobs or handles, offering simple operation and suitability for fixed workpiece types or small-batch production. Automatic regulating valves utilize sensors and controllers to automatically adjust the airflow based on the workpiece's shape and weight, making them suitable for large-scale production and automated production lines.

[0062] The manual regulating valve uses a knob or handle type, allowing users to manually adjust the air flow according to their actual needs.

[0063] The automatic regulating valve uses a solenoid valve or a pneumatic proportional valve. The position and weight of the workpiece are detected by a sensor, and the controller automatically adjusts the air flow according to preset parameters.

[0064] The conveying assembly 2 includes a conveying element 21 and a guide element 22. The conveying element 21 is used to carry and convey the workpiece. The conveying element 21 is disposed on the mounting frame 1, and the guide element 22 is mounted on the conveying element 21 to restrict the orientation of the workpiece.

[0065] The conveyor 21, mounted on the mounting frame 1, is used to carry and transport workpieces. The conveyor 21 can be a conveyor belt, conveyor rollers, or other suitable conveying method. In this embodiment, the conveyor 21 is a conveyor belt, driven by a motor, capable of transporting workpieces from one station to another at a certain speed.

[0066] The guide member 22 is mounted on the conveyor 21 to limit the orientation of the workpiece and ensure that the workpiece maintains a stable position and orientation during the conveying process. The guide member 22 can take various structural forms, such as baffles, guide rails, or positioning grooves.

[0067] Preferably, the guide member 22 includes a first guide portion 221 and a second guide portion 222, which are disposed opposite to and spaced apart on the conveyor member 21 to form a flow channel for the workpiece to pass through.

[0068] The first guide section 221 and the second guide section 222 adopt a baffle structure to ensure that the workpiece does not deviate from the predetermined path during the conveying process.

[0069] The baffle is made of wear-resistant and corrosion-resistant materials, such as stainless steel or aluminum alloy, to ensure its durability and stability.

[0070] The width of the flow channel between the first guide section 221 and the second guide section 222 should be designed according to the size of the workpiece to ensure that the workpiece can pass through the flow channel smoothly while restricting the lateral movement of the workpiece.

[0071] The shape of the flow channel can be optimized according to the shape of the workpiece, such as using a straight line, an arc, or other suitable shape, to ensure that the workpiece maintains a stable orientation during the conveying process.

[0072] The guide component 22 also includes an elevated mounting section (not shown in the figure), which is connected to the mounting frame 1 and to the first guide section 221 and the second guide section 222, so that the first guide section 221, the second guide section 222 and the conveyor 21 are spaced 3-5mm apart.

[0073] The elevated mounting section is connected to the mounting frame 1 and to the first guide section 221 and the second guide section 222. Its function is to elevate the first and second guide sections 221 and 222, maintaining a 3-5mm gap between them and the conveyor component 21 to prevent wear on the conveyor component 21. The elevated mounting section can use a metal or plastic bracket, selecting the appropriate material and structure according to actual needs. The elevated mounting section can be connected to the mounting frame 1, the first guide section 221, and the second guide section 222 via bolts or clips for easy installation and adjustment.
