[0002] Laser welding of energy storage modules has become one of the core processes in modern energy storage battery manufacturing due to its high precision, high efficiency and high reliability. It is widely used, especially in power batteries for new energy vehicles and battery modules for energy storage power stations.

[0003] Existing laser welding of energy storage modules often uses clamping modules or pressure head modules to clamp and fix the welding positions on the energy storage module to facilitate welding operations. However, existing clamping modules or pressure head modules cannot accurately judge the pressure applied to the energy storage module during the actual clamping operation. This can lead to excessive pressure damaging the energy storage module, or insufficient pressure resulting in inaccurate positioning of the welding position and poor welding effect. Summary of the Invention

[0055] Example 1:

[0056] Please see Figures 1-3 An automatic laser welding device for energy storage modules includes a conveying mechanism 100, a welding mechanism 200, two pressure claw mechanisms 300, and two cleaning and dust extraction mechanisms 400, for automated laser welding of energy storage modules and automatic cleaning and dust extraction of the pressure claw mechanism 300.

[0057] The welding mechanism 200 is used for welding the energy storage module. The welding mechanism 200 is located above the conveying mechanism 100. The conveying mechanism 100 conveys the energy storage module to the welding mechanism 200, where it awaits welding. The two clamping claw mechanisms 300 and the two cleaning and dust extraction mechanisms 400 are located on both sides of the conveying direction of the conveying mechanism 100. That is, on one side of the conveying direction of the conveying mechanism 100, the clamping claw mechanism 300 and the cleaning and dust extraction mechanism 400 are arranged adjacent to each other. Correspondingly, on the other side of the conveying direction of the conveying mechanism 100, the clamping claw mechanism 300 and the cleaning and dust extraction mechanism 400 are also arranged adjacent to each other. The clamping claw mechanism 300 is used to clamp the position of the energy storage module to be welded, so that the welding mechanism 200 can perform welding. The cleaning and dust extraction mechanism 400 is used to clean and extract dust from the clamping claw mechanism 300 after the welding operation.

[0058] As can be seen, in this embodiment, there is one conveying mechanism 100 and one welding mechanism 200, while there are two clamping claw mechanisms 300 and two cleaning and dust extraction mechanisms 400. This arrangement is because only one conveying mechanism 100 is needed to complete the conveying operation of the energy storage module. Before welding, the welding mechanism 200 needs to clamp the energy storage module through the clamping claw mechanism 300. After the welding is completed, the cleaning and dust extraction mechanism 400 needs to clean and extract dust from the clamping claw mechanism 300. Therefore, setting two clamping claw mechanisms 300 and two cleaning and dust extraction mechanisms 400 is to facilitate the cleaning and dust extraction operation of the clamping claw mechanism 300 on the other side when the welding mechanism 200 is performing welding operations through the clamping claw mechanism 300 on one side, thus avoiding affecting the welding operation and effectively improving the welding quality and welding efficiency.

[0059] Specifically, the pressure claw mechanism 300 includes a first moving module 310, a mounting base 320, a sensor module 330, an elastic buffer module 340, and a pressure claw module 350. The drive end of the first moving module 310 is connected to the mounting base 320. The sensor module 330 and the elastic buffer module 340 are both mounted on the mounting base 320. The upper end of the elastic buffer module 340 is connected to the sensor module 330, and the lower end of the elastic buffer module 340 is connected to the pressure claw module 350.

[0060] The pressure claw module 350 is used to press the position to be welded on the energy storage module, and the pressure claw module 350 has a welding hole for the laser penetration of the welding mechanism 200. The cleaning and dust extraction mechanism 400 is used to clean and extract dust from the welding hole. The sensor module 330 can be a sensor capable of pressure detection, such as a pressure sensor.

[0061] In actual operation, after the energy storage module is conveyed to its position by the conveying mechanism 100, the pressure claw module 350 located on one side of the conveying mechanism 100 moves to the top of the energy storage module under the action of the first moving module 310 and presses against the position to be welded on the energy storage module. During this pressing process, the elastic buffer module 340 ensures flexible contact between the pressure claw module 350 and the energy storage module, and the sensor module 330 detects the pressing force of the pressure claw module 350 to provide feedback information so that the equipment system control terminal can control the stopping of the driving operation of the first moving module 310. Subsequently, the welding mechanism 200 performs laser welding through the welding hole on the pressure claw module 350. After the welding is completed, the cleaning and dust extraction mechanism 400 cleans and extracts dust from the welding hole of the pressure claw module 350 on this side, while the welding mechanism 200 moves to the pressure claw mechanism 300 located on the other side of the conveying mechanism 100 to perform welding operations on the energy storage module on this side.

[0062] This embodiment provides an automatic laser welding device for energy storage modules. It incorporates an elastic buffer module 340 to cushion the pressure from the pressure claw module 350, preventing damage to the energy storage module from hard contact and ensuring product quality. A sensor module 330 detects the pressure from the pressure claw module 350, ensuring appropriate pressure and preventing damage from excessive pressure, thus effectively improving welding efficiency.

[0063] In some embodiments, the elastic buffer module 340 includes a connecting plate 341 and a spring 342; the upper end of the spring 342 is connected to the sensor module 330, the lower end of the spring 342 is connected to the upper end of the connecting plate 341, and the lower end of the connecting plate 341 is connected to the pressure claw module 350. By utilizing the elastic buffering effect of the spring 342 and the transmission effect of the connecting plate 341, a flexible contact effect is achieved between the pressure claw module 350 and the energy storage module.

[0064] Furthermore, the pressure claw mechanism 300 also includes a guide rail module 360; the guide rail module 360 ​​is distributed on the mounting base 320 along the axial direction, that is, the guide rail module 360 ​​is distributed from top to bottom, and the connecting plate 341 has a sliding groove for sliding connection with the guide rail module 360, so that the connecting plate 341 can move stably up and down along the guide rail module 360. Here, by setting the guide rail module 360 ​​and the sliding connection relationship with the connecting plate 341, the movement stability of the connecting plate 341 is ensured, thereby ensuring the elastic transmission stability of the spring 342.

[0065] Example 2:

[0066] This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-3 Based on the above Figures 4-6 .

[0067] In this embodiment, the automatic laser welding equipment for energy storage modules also includes a bidirectional drive mechanism 500; the two drive ends of the bidirectional drive mechanism 500 are respectively connected to the first moving modules 310 of the two pressure claw mechanisms 300. Through a bidirectional drive mechanism 500, the two pressure claw mechanisms 300 can play an independent driving role, reducing the design of mechanical structures and facilitating the overall control of the equipment.

[0068] The bidirectional drive mechanism 500 has a bidirectional driver, that is, two drive ends, which can drive the first moving modules 310 of the two pressure claw mechanisms 300 respectively. For example, the bidirectional drive mechanism 500 can be configured to drive the two pressure claw mechanisms 300 to move along the conveying direction of the conveying mechanism 100 respectively, or drive the two pressure claw mechanisms 300 to move closer or further away from each other respectively. As for the position movement required by the pressure claw mechanism 300 in the specific operation process, it can be moved by its own first moving module 310.

[0069] For example, in one embodiment, the bidirectional drive mechanism 500 is used to drive the first moving module 310 of the pressure claw mechanism 300 to move along the X-axis direction, and the first moving module 310 can drive the pressure claw module 350 to move in the Y-axis direction and the Z-axis direction. Of course, in order to achieve a larger range of movement, the first moving module 310 can also drive the pressure claw module 350 to move in the X-axis direction.

[0070] In some embodiments, the cleaning and dust extraction mechanism 400 includes a mounting frame 410, a second moving module 420, a cleaning module 430, and a dust extraction module 440. The second moving module 420 and the dust extraction module 440 are both mounted on the mounting frame 410. The cleaning module 430 is connected to the drive end of the second moving module 420 and is located above the dust extraction module 440. The cleaning and dust extraction mechanism 400 realizes the automated cleaning and dust extraction function of the pressure claw module 350.

[0071] During the specific operation, the pressure claw module 350 can be driven by the first moving module 310 to be located between the cleaning module 430 and the dust extraction module 440. Under the action of the second moving module 420, the cleaning module 430 moves downward to the welding hole position of the corresponding pressure claw module 350 and cleans the pressure claw module 350. At the same time, the dust extraction module 440 collects the dust.

[0072] For example, the cleaning module 430 includes a brush and a motor connected to the brush. The motor drives the brush to rotate and cleans the welding holes of the pressure claw module 350. The dust extraction module 440 is connected to an external air valve generator to extract and collect dust.

[0073] It should be noted that the pressure claw module 350 can be equipped with multiple welding holes for laser penetration. Correspondingly, the number of brushes on the cleaning module 430 corresponds to the number of welding holes, so as to achieve a one-to-one corresponding cleaning effect and improve work efficiency.

[0074] Example 3:

[0075] This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-3 Based on the above Figures 7-9 .

[0076] In this embodiment, the conveying mechanism 100 includes a conveying carrier 110 and a first conveyor belt 120 and a second conveyor belt 130 that are distributed in parallel. The conveying carrier 110 is located on the first conveyor belt 120 and the second conveyor belt 130 for conveying. The conveying carrier 110 is used to carry and position the energy storage module. The positional stability of the energy storage module during operation is improved by means of the conveying carrier 110.

[0077] The conveyor 110 is used to carry and position the energy storage module so that it can be transported via the first conveyor belt 120 and the second conveyor belt 130.

[0078] In some embodiments, the conveying mechanism 100 further includes a positioning sensor 140; the positioning sensor 140 is located between the first conveyor belt 120 and the second conveyor belt 130, and is used to detect the positioning of the conveying vehicle 110 to ensure the accuracy of the conveying positioning of the conveying vehicle 110.

[0079] The position sensor 140 is located between the first conveyor belt 120 and the second conveyor belt 130, and is located on the conveying path of the conveying carrier 110. When the position sensor 140 detects that the conveying carrier 110 has arrived, it sends feedback information to the equipment system control terminal, causing the conveying mechanism 100 to stop the conveying operation.

[0080] In some embodiments, the conveying mechanism 100 further includes a blocking module 150; the blocking module 150 is located between the first conveyor belt 120 and the second conveyor belt 130, and is used to block the conveying of the conveying vehicle 110, prevent the conveying vehicle 110 from continuing to convey, and improve the stability of the operation.

[0081] For example, after the positioning sensor 140 detects that the conveyor 110 has arrived at its position, the blocking module 150 blocks the continued conveying of the conveyor 110, and simultaneously, the conveying mechanism 100 stops its conveying operation. The blocking module 150 may include a blocking cylinder and a blocking block. The driving end of the blocking cylinder is connected to the blocking block, and the blocking block extends under the driving action of the blocking cylinder to block the conveyor 110.

[0082] In some embodiments, the conveying mechanism 100 further includes an upper support module 160; the upper support module 160 is located between the first conveyor belt 120 and the second conveyor belt 130, and is used to support the conveying vehicle 110. After the conveying vehicle 110 is conveyed into place, the upper support module 160 supports the conveying vehicle 110.

[0083] The upper support module 160 includes an upper support cylinder 161, an upper support plate 162, and a level detector 163. The drive end of the upper support cylinder 161 is connected to the upper support plate 162. The level detector 163 is set on the upper support plate 162 and is used to detect the levelness of the upper support plate 162 to ensure the levelness of the energy storage module, thereby improving the quality of welding operations.

[0084] The upper support plate 162 is provided with a positioning pin 164 for positioning with the conveyor 110. Understandably, the conveyor 110 is provided with a positioning hole that matches the positioning pin 164. Through the cooperation of the positioning pin 164 and the positioning hole, the positioning accuracy of the conveyor 110 and the energy storage module is ensured. The upper support plate 162 supports and positions the conveyor 110, and the levelness of the upper support plate 162 is detected by the level detector 163, which effectively improves the stability of the operation.

[0085] Example 4:

[0086] This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-3 Based on the above Figure 10 .

[0087] In this embodiment, the device further includes a vision inspection mechanism 600; the welding mechanism 200 includes a third moving module 210 and a welding module 220. The driving end of the third moving module 210 is connected to the welding module 220 and the vision inspection mechanism 600. The vision inspection mechanism 600 can be used to inspect the welding quality to ensure the work effect.

[0088] The third moving module 210 can drive the welding module 220 and the vision inspection mechanism 600 to move in different directions. For example, the third moving module 210 can drive the welding module 220 and the vision inspection mechanism 600 to move in the X-axis, Y-axis and Z-axis directions. In this example, the welding module 220 and the vision inspection mechanism 600 are driven synchronously by the third moving module 210. Therefore, the distance between the welding module 220 and the vision inspection mechanism 600 can be set to the distance of a welding position. When the welding module 220 completes the welding operation at this position and is driven to the next welding position by the third moving module 210, the vision inspection mechanism 600 moves to the position where the welding operation has been completed to perform welding inspection.

[0089] In this embodiment, a visual inspection mechanism 600 is set up to inspect the welding quality, which can ensure the operation effect. It is driven to move by the third moving module 210, just like the welding module 220, which effectively reduces the setting of mechanical structure and facilitates the control of the overall equipment.

[0090] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
