Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a sealing nail feeding mechanism, device, and sealing nail welding machine. Background Technology

[0002] In battery manufacturing, the airtightness of a battery is one of the key factors ensuring its performance and safety. Sealing pin welding technology, as an important step in the battery manufacturing process, plays a particularly significant role for cylindrical batteries and some prismatic batteries. This technology involves precisely welding sealing pins to the battery's electrolyte filling hole to ensure that the electrolyte inside the battery does not leak to the outside, while preventing external contaminants from entering the battery. This is crucial for the battery's stability and safety. Furthermore, the sealing pins also act as a safety valve, providing pressure relief protection in case of abnormal internal battery pressure, preventing dangerous situations such as battery explosions.

[0003] However, existing battery manufacturing technologies have limitations in the feeding devices for sealing pins. Especially when handling ultra-thin sealing pins, overlap is prone to occur. Feeding overlapping sealing pins to the welding station severely affects welding quality, resulting in defective products and increasing production costs.

[0004] Therefore, in view of the problems existing in the prior art, an improved sealing nail feeding device is provided. This device can effectively avoid the impact of the overlap of ultra-thin sealing nails on welding, thereby ensuring welding quality, ensuring the airtightness and safety of the battery, and reducing production costs. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a sealing nail feeding mechanism, device and sealing nail welding machine, which can effectively avoid the influence of the overlap of ultra-thin sealing nails on the welding, thereby ensuring the welding quality, ensuring the airtightness and safety of the battery, and reducing production costs.

[0011] Furthermore, it also includes a backlight source;

[0012] The detection plate is transparent;

[0013] The backlight source is installed at the bottom or side of the detection plate and is used to project light onto the detection plate.

[0014] Furthermore, the first detector is a CCD camera, which is positioned above the detection disk.

[0015] Furthermore, it also includes a feeding tray and a second vibration source;

[0016] The feeding tray is located above one side of the detection tray and has a feeding port for feeding sealing nails to the detection tray;

[0017] The second vibration source is connected to the feeding tray and is used to drive the feeding tray to vibrate so as to convey the sealing nails in the feeding tray toward the feeding port.

[0018] Furthermore, the second vibration source is a linear vibrator;

[0019] The feeding tray is installed on the second vibration source.

[0020] Furthermore, an opening is provided on one side of the feeding tray;

[0021] A guide groove that connects to the opening is provided on one side of the feeding tray;

[0022] The guide groove gradually narrows from one end connected to the opening to the other end;

Obviously, the described embodiments are only some embodiments of the embodiments of this application, and not all embodiments.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0043] This application discloses a sealing nail feeding mechanism, device, and sealing nail welding machine.

[0044] Please see Figure 1 as well as Figure 2 One embodiment of the sealing nail feeding mechanism provided in this application includes:

[0045] The first vibration source 11, the detection plate 12, and the first detector 15.

[0046] The inspection plate 12 is used to hold the sealing nails to be loaded.

[0047] The first detector 15 is used to detect whether the sealing pins on the detection disk 12 overlap.

[0048] The first vibration source 11 is connected to the detection disk 12 and is used to drive the detection disk 12 to vibrate when the first detector 15 detects overlapping sealing nails, so as to shake the overlapping sealing nails apart.

[0049] The sealing nail feeding mechanism designed in this application uses a first detector 15 to carefully detect overlap of the sealing nails placed on the detection tray 12 for feeding. The first detector 15 confirms that sealing nails without overlap can be fed normally; when the first detector 15 detects overlapping sealing nails, it activates a first vibration source 11 to vibrate the detection tray 12 and disperse the overlapping sealing nails. This innovative design effectively prevents overlapping sealing nails from being incorrectly fed to the welding station, thereby significantly improving the stability of the sealing nail feeding process. In this way, we can ensure the quality of the welding process, guarantee the airtightness and safety of the battery, and reduce overall production costs.

[0050] The above is Embodiment 1 of the sealing nail feeding mechanism provided in this application. The following is Embodiment 2 of the sealing nail feeding mechanism provided in this application. Please refer to the following for details. Figures 1 to 2 .

[0051] Based on the solution of Embodiment 1 above:

[0052] Furthermore, the detection disc 12 is a flexible disc, which is mounted on the first vibration source 11. The flexible disc has a certain degree of elasticity, enabling it to better adapt to the vibrations generated by the first vibration source 11, thus improving the dissipation effect of the sealing pins on the detection disc 12. The detection disc 12 can be directly mounted on the first vibration source 11, specifically as follows: Figure 1 As shown, it is installed on top of the first vibration source 11, making the overall structure more compact.

[0053] Furthermore, it also includes a backlight source (not shown in the figure), and the detection disk 12 is transparent; the backlight source is installed at the bottom or side of the detection disk 12 to project light onto the detection disk 12.

[0054] The detection disk 12 can be made using the same light guide plate material used to prepare the light guide plate, without any limitations. By projecting light onto the detection disk 12 through a backlight source, the first detector 15 can more clearly capture the image of the sealing nail on the detection disk 12, thereby improving the detection accuracy.

[0055] Furthermore, such as Figure 2 As shown, the first detector 15 is a CCD camera, positioned above the detection disk 12. The CCD camera features high resolution and fast response, enabling it to capture image information within the detection area in real time and transmit this information to the control system for processing. Through image processing algorithms, the control system can accurately identify the contour, position, and presence of overlap of the sealing nails, thereby achieving precise detection of the sealing nails. This CCD camera-based detection method not only improves the accuracy and efficiency of detection but also reduces the need for manual intervention, making the entire loading process more automated and intelligent.

[0056] Furthermore, it also includes a feeding tray 14 and a second vibration source 13; the feeding tray 14 is disposed above one side of the detection tray 12 and has a feeding port 141 for feeding sealing nails to the detection tray 12; the second vibration source 13 is connected to the feeding tray 14 and is used to drive the feeding tray 14 to vibrate, so as to feed the sealing nails in the feeding tray 14 towards the feeding port 141. The feeding tray 14 generates a vibration effect through the driving force of the second vibration source 13. This vibration not only causes the sealing nails to disperse in the tray, but also guides them to be neatly arranged and fed one by one along the specific feeding port 141. This design greatly reduces the overlap of sealing nails when feeding to the detection tray 12, and further improves the accuracy and efficiency of feeding.

[0057] Furthermore, the second vibration source 13 is a linear vibrator; a linear vibrator, also known as a linear vibration source or linear feeder (linear vibrator), is a mechanical device capable of generating linear vibration. A linear vibrator is a commonly used vibration device that achieves functions such as material conveying, screening, and compaction by generating linear vibration. Besides linear vibrators, other vibrators with the same function can also be used, including but not limited to: pneumatic vibrators: pneumatic vibrators are driven by compressed air to produce a strong vibration effect, suitable for cleaning, conveying, compaction, and other applications requiring high-intensity vibration. Those skilled in the art can select a suitable vibrator according to actual needs.

[0058] like Figure 1 As shown, the feeding tray 14 is installed on the second vibration source 13; the feeding tray 14 can be directly installed on the second vibration source 13, specifically as follows. Figure 1 As shown, it is installed on top of the second vibration source 13, making the overall structure more compact.

[0059] Furthermore, an opening is provided on one side of the feeding tray 14; a guide groove 142 extending from one side of the feeding tray 14 and communicating with the opening is provided; the guide groove 142 gradually narrows from one end connecting to the opening to the other end; the feeding port 141 is located at the other end of the guide groove 142. This design allows the sealing nails to move smoothly along the guiding direction of the guide groove 142 during the feeding process, and finally enter the feeding port 141 through the narrowed guide groove 142. The gradually narrowing design of the guide groove 142 helps to guide and organize the sealing nails, ensuring that they can be neatly arranged and enter the feeding port 141, further improving the accuracy and efficiency of feeding. At the same time, the opening and the guide groove 142 also facilitate the replenishment and replacement of sealing nails, improving the ease of use and flexibility of the equipment.

[0060] The guide groove 142 and the feeding tray 14 are integrally molded, which not only enhances the stability and durability of the overall structure, but also reduces the assembly process.

[0061] like Figure 2As shown, this application also discloses a sealing nail feeding device, including a feeding robot 21, a second detector 22, and a sealing nail feeding mechanism.

[0062] The first detector 15 of the sealing nail feeding mechanism is also used to perform a primary positioning of the sealing nails on the detection plate 12 (coarse positioning of the center of the sealing nail).

[0063] A loading robot 21 is positioned on one side of the sealing nail loading mechanism to transport the sealing nails from the inspection plate 12 to the welding station. The precise operation of the loading robot 21 ensures that the sealing nails are accurately placed on the welding station, providing a good foundation for subsequent welding operations. The movement trajectory and speed of the loading robot 21 can be precisely adjusted by the control system to accommodate sealing nails of different specifications and sizes, improving the flexibility and adaptability of the equipment.

[0064] The loading robot 21 can be a three-axis or higher multi-axis robot, offering higher motion precision and degrees of freedom. This design allows the loading robot 21 to flexibly handle various complex loading tasks, ensuring that the sealing nails can be stably and accurately grasped and placed in the designated position. Furthermore, the use of a multi-axis robot improves the reliability and stability of the entire loading process, further enhancing production efficiency and product quality.

[0065] The second detector 22 is set between the detection plate 12 and the welding station to perform secondary positioning (precision positioning) on ​​the sealing nails that are conveyed through.

[0066] The second detector 22 further improves the positioning accuracy of the sealing nail. During the process of the sealing nail being transported from the detection plate 12 to the welding station, the second detector 22 can perform secondary positioning to ensure that the sealing nail is in the correct position before welding. This secondary positioning not only improves the accuracy and stability of welding but also helps reduce welding defects and defect rates caused by inaccurate positioning. The second detector 22 can also employ a high-resolution CCD camera, using image processing algorithms to achieve accurate identification and positioning of the sealing nail.

[0067] like Figure 3 As shown, this application also discloses a sealing nail welding machine, including a conveying device 31 and a welding device sealing nail feeding device.

[0068] The conveying device 31 is located on one side of the sealing nail feeding device and can be a linear module used to convey the battery to be welded to the welding station.

[0069] The design of the conveyor 31 ensures that the batteries to be welded can be stably and continuously transported to the welding station, providing reliable support for subsequent welding operations. The movement speed and control precision of the conveyor 31 can be precisely adjusted by the control system to accommodate batteries of different specifications and sizes, improving the flexibility and adaptability of the equipment.

[0070] Linear modules used for conveying materials include, but are not limited to: ball screw linear modules (ball screw type linear modules), belt linear modules (synchronous belt modules), linear motor modules, etc., and those skilled in the art can make variations in design according to actual needs.

[0071] The welding device includes a laser 32 and a third detector 33; the third detector 33 is used to locate the liquid injection hole of the battery to be welded in the welding station; the laser 32 is set above the welding station and is used to weld the sealing nail to the liquid injection hole.

[0072] Laser 32, by precisely controlling the focus and power of the beam, can quickly and accurately weld the sealing pin to the battery's electrolyte filling hole. This welding method not only improves welding efficiency but also ensures the stability and consistency of welding quality. Simultaneously, the use of laser 32 reduces problems such as heat-affected zones and deformation that may occur in traditional welding methods, further enhancing the overall product quality. The third detector 33 can also employ a high-resolution CCD camera, using image processing algorithms to accurately identify and locate the electrolyte filling hole, providing accurate positional information for the laser 32's welding operation.

[0073] Furthermore, the optical central axis of the third detector 33 coincides with the optical central axis of the laser 32. This design ensures that during welding operations, the third detector 33 can accurately capture the position of the injection hole and feed this information back to the laser 32 in real time, thereby achieving precise welding of the sealing nail. The coincidence of the optical central axes not only simplifies the equipment calibration process but also improves the accuracy and stability of welding, further enhancing the overall product quality and production efficiency.

[0074] The sealing nail feeding mechanism, device, and sealing nail welding machine provided in this application have been described in detail above. For those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the embodiments of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
