Description

Technical Field

[0001] The utility model relates to the technical field of welding compression, in particular to an adjustable welding compression platform. Background Art

[0002] A welding hold-down table is a fixture used specifically in welding operations. It is designed to clamp and stabilize the workpiece, ensuring it remains precisely and securely positioned during the welding process. This is crucial for improving welding quality and efficiency, especially in automated and semi-automated welding production lines. A welding hold-down table typically features adjustable clamps and a clamping mechanism that can be tailored to the size and shape of the workpiece. Some are also equipped with vacuum cups or magnetic devices to enhance the holding effect. Such equipment prevents thermal deformation during welding and ensures a smooth and consistent weld seam.

[0003] The position of the clamping block on the current battery welding clamping table is fixed. Since the position of the clamping block cannot be adjusted, the existing clamping table can only be used for batteries with the same welding height. This means that when batteries of different heights or sizes need to be processed, the entire clamping table must be replaced or additional adjustments must be made, which increases the complexity and cost of the operation. The fixed-position clamping block limits the versatility and utilization of the equipment. In actual production, different batches of batteries may have different specifications. The fixed-position clamping block cannot meet such diverse needs, thereby reducing the versatility and production efficiency of the equipment.

[0004] Therefore, it is necessary for us to design an adjustable welding pressing table. Utility Model Content

DETAILED DESCRIPTION

[0019] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of such a phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] Example: An adjustable welding pressing table, such as Figures 1-4As shown, it includes a fixed frame 1, a guide rail block I2, a slider I3, a guide rail block II4, a slider II5, a bidirectional screw 6, a clamping plate 7, a cylinder 9, a connecting block 10, a connecting screw 11, an adjusting block 12 and a clamping block 13. The fixed frame 1 is connected to the guide rail block I2, the guide rail block I2 is slidably connected to the slider I3, the slider I3 is connected to the guide rail block II4, the guide rail block II4 is slidably connected to the slider II5, the slider II5 is rotatably connected to the bidirectional screw 6, the bidirectional screw 6 is symmetrically threaded with a clamping plate 7, the slider II5 is installed with a cylinder 9, the telescopic end of the cylinder 9 is connected to the connecting block 10, and the connecting block 10 is rotatably connected to the connecting screw 11. The connecting screw 11 is connected to an adjusting block 12, which is slidably connected to the connecting block 10. The adjusting block 12 is connected to a clamping block 13, which can be disassembled and replaced. The device can replace the clamping block 13 according to the welding requirements of the battery, which effectively improves the adaptability and utilization of the device. The device is located in the clamping welding link in the battery production, and is connected to the robot arm installed on the production line for welding. When the device is to be used, the battery to be welded is first placed on the guide block II 4, and then the bidirectional screw 6 is rotated to move the clamping plate 7 to the middle. In this process, the clamping plate 7 will correct the placement of the battery, so that The present device can not only fix the battery, but also place the battery in the best welding position; while the pressing plate 7 clamps the battery, it can also press the battery sideways, and then drive the robotic arm to weld the side panels of the battery, thereby further reinforcing the stability between the battery shells, thereby ensuring that the battery can maintain good structural integrity when subjected to external impact; after the pressing plate 7 fixes the battery, the bar to be welded is placed at the battery welding position, and the cylinder 9 is driven. The telescopic end of the cylinder 9 will move downward with the connecting block 10, and the connecting screw 11 will move downward with the adjusting block 12 and the pressing block 13. If the rubber block Ⅰ141 on the pressing block 13 is It can contact the tab and apply force to press it. The rubber block Ⅰ141 made of flexible material can better spread the pressure, so that the tab is evenly stressed, and then the robotic arm is driven to weld the tab. If the pressing block 13 fails to contact the tab at this time, the connecting screw 11 is rotated to move the connecting screw 11 and the pressing block 13 downward together until the rubber block Ⅰ141 on the pressing block 13 can contact and press it, and then the robotic arm is driven to weld the tab, so that the device can fix and weld batteries of different sizes, thereby enabling the device to meet the diverse needs of battery production, effectively improving the versatility and production efficiency of the device.

[0021] like Figure 1 、 Figure 3 and Figure 4As shown, it also includes a rubber block II 8. The sides of the compression plates 7 that are close to each other are connected with rubber blocks II 8. The rubber blocks II 8 made of flexible material can better correct the position of the battery, and when the battery is pressed sideways, the flexible compression can better spread the pressure and make the battery evenly stressed.

[0022] like Figure 2 and Figure 4 As shown, it also includes a servo motor II 17 and an adjusting screw II 18. The servo motor II 17 is installed on the slider I 3 through a fixing part. The adjusting screw II 18 is connected to the output shaft of the servo motor II 17 through a coupling. The slider II 5 is threadedly connected to the adjusting screw II 18. When it is necessary to weld the bar to the battery module, first rotate the bidirectional screw 6 to expand the distance between the clamping plates 7 to the maximum value, and then place the battery module vertically on the guide rail block II 4, and then rotate the bidirectional screw 6 to correct the placement of the battery module through the clamping plate 7, and clamp the battery module, drive the robot arm to weld the side plate of the battery module, and then place the bar to be welded at the welding position on the battery module, drive the cylinder 9 to make the clamping block 13 contact and clamp the bar, and then drive the robot arm to weld the bar. After completing the welding of the bar at the rear of the battery module, drive the cylinder 9 to move the clamping block 13 upward, and drive the servo Motor Ⅱ 17, the output shaft on the servo motor Ⅱ 17 will drive the adjusting screw Ⅱ 18 to rotate, and the slider Ⅱ 5 will move forward with the rotation of the adjusting screw Ⅱ 18, thereby driving the clamping block 13 forward together. When the clamping block 13 moves to the position where the next welding point needs to be clamped, the bar to be welded is placed on the welding position on the battery module, and then the servo motor Ⅱ 17 is turned off to stop the clamping block 13 from moving forward, and then the cylinder 9 is driven to make the clamping block 13 contact and clamp the bar, and then the robotic arm is driven to weld the bar. Before the slider Ⅱ 5 moves forward, the bidirectional screw 6 is rotated to move the clamping plate 7 to the left and right, so that the clamping plate 7 only contacts the battery module without applying force. At the same time as the slider Ⅱ 5 moves forward, the clamping plate 7 will also move forward and limit the front battery module. After determining the welding position, the clamping plate 7 clamps the battery module, and then the robotic arm is driven to weld the battery module side panel. Repeat the above steps to complete the subsequent welding work of the battery module, so that the device can not only weld and press the battery, but also weld and press the battery module, further improving the versatility and production efficiency of the device.

[0023] like Figure 2As shown, it also includes a servo motor Ⅰ15 and an adjusting screw Ⅰ16. The servo motor Ⅰ15 is installed on the fixing frame 1 through a fixing part. The output shaft of the servo motor Ⅰ15 is connected to the adjusting screw Ⅰ16 through a coupling. The slider Ⅰ3 is threadedly connected to the adjusting screw Ⅰ16. When the device needs to weld different batteries or battery packs, since the welding parameters set for each robot arm are inconsistent, after replacing the corresponding clamping plate 7, the servo motor Ⅰ15 is driven, and the output shaft of the servo motor Ⅰ15 will rotate with the adjusting screw Ⅰ16. The slider Ⅰ3 will move to the left with the rotation of the adjusting screw Ⅰ16, thereby moving the components installed on the slider Ⅰ3 to the left together. The servo motor Ⅰ15 can be turned off before the displacement reaches the robot arm with the corresponding welding parameters, thereby effectively improving the welding efficiency of the device and effectively saving the time for adjusting the robot arm parameters.

[0024] like Figure 3 and Figure 4 As shown, it also includes a shielding gas introduction component 15. The shielding gas introduction component 15 is connected to the compression block 13. The shielding gas introduction component 15 includes an introduction pipe and a shielding gas introduction controller. The external shielding gas device is connected to the introduction pipe, and the shielding gas introduced is adjusted to a preset index through the shielding gas introduction controller, so that the device can effectively improve the welding quality.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
