Specific embodiments

[0023] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figures 1-3 , a box body welding device, including a workbench 100 and a frame edge groove 140 opened on the workbench 100. A welding mechanism 400 that slides on the workbench 100 in the linear direction of the frame edge groove 140, and a first lifting mechanism 200 corresponding to the bottom of the frame edge groove 140 are provided at the bottom of the workbench 100.

[0025] The workbench 100 serves as the base of the entire welding device. The workbench 100 provides a stable platform for placing and supporting the position of the box body during the welding process. The frame edge groove 140 opened on the workbench 100 is designed to fix the edge of the box body to ensure the stability and precise alignment of the box body during the welding process. The welding mechanism 400 slides on the workbench 100 in the linear direction of the frame edge groove 140 to perform the welding task. The first lifting mechanism 200 is provided at the bottom of the workbench 100, corresponding to the bottom of the frame edge groove 140, and is used to adjust the height of the box body to adapt to box bodies of different thicknesses or shapes.

[0026] The box body is placed on the first lifting mechanism 200. Through the lifting action of the lifting mechanism, the box body is lifted to an appropriate position of the frame edge groove 140. When the first lifting mechanism 200 lifts the box body, the edge of the box body contacts the inclined side of the frame edge groove 140. The frame edge groove 140 can serve as a guide to help the box body align and adapt to the welding path of the welding mechanism 400. As the box body is lifted to the welding position, the welding mechanism 400 moves linearly along the workbench 100 to precisely weld the box body border.

[0027] Furthermore, both sides inside the frame edge groove 140 are inclined downward.

[0028] The inner sides of the frame edge groove 140 slope downward, providing a guiding surface for the box body, which helps to accurately position the box body during the jacking process and ensures the accurate relative position between the box body and the welding mechanism 400. When the box body is jacked up, the frame of the box body is flush with the inclined frame edge groove 140, which can increase the contact flatness between the box body and the frame edge groove, thereby improving the stability of the box body during the welding process.

[0029] Furthermore, the welding mechanism 400 includes a linear track 420 and a welding control box 410 that slides on top of it. An adjustment bracket 430 is provided on the top of the welding control box 410 and is connected to a welding gun 440.

[0030] The linear track 420 serves as the moving guide rail for the welding control box 410. The linear track 420 provides a stable and accurate moving path to ensure that the welding control box 410 slides smoothly along a predetermined direction. The welding control box 410 is located on the linear track 420. The welding control box 410 may contain controllers, sensors, and other electronic components required during the welding process to control welding parameters and operate the welding gun 440. The adjustment bracket 430 is installed on the top of the welding control box 410. The adjustment bracket 430 is used to fix the welding gun 440 and allows for fine adjustment of the position and angle of the welding gun to adapt to different welding requirements. The welding gun 440 is the tool that performs the actual welding task. It is connected to the welding control box 410 through the adjustment bracket 430 to ensure the accuracy and consistency of the welding process.

[0031] The welding control box 410 is placed on the linear track 420. The adjustment bracket 430 fixes the welding gun 440 and makes initial settings according to the requirements of the welding task. The welding control box 410 slides along the linear track 420 and moves to the predetermined welding position above the frame edge groove 140. Through the adjustment bracket 430, the operator can fine-tune the position and angle of the welding gun 440 to ensure the accuracy of welding and meet the requirements of different welding points. Once the welding control box 410 and the welding gun 440 are positioned, the welding process is started. The welding gun 440 welds along the edge of the box body under the control of the welding control box 410.

[0032] Furthermore, the output end of the welding gun 440 corresponds to the frame edge groove 140.

[0033] This design ensures that the output end (i.e., the welding point) of the welding gun 440 can accurately align with the edge of the box body, which is the most critical part of the welding process. It means that the welding gun 440 can perform precise welding along the edge of the box body under the guidance of the frame edge groove 140.

[0034] Further, a support frame 110 is provided at the bottom of the workbench 100, and both sides of the bottom of the support frame 110 slide on the optical axes 120 provided at the bottom of the workbench 100; the top of the support frame 110 is connected to the bottom of the first lifting mechanism 200.

[0035] The support frame 110 is provided at the bottom of the workbench 100. The support frame 110 plays a role in supporting and stabilizing the box body, ensuring the stability of the box body during the welding process. The optical axes 120 are provided at the bottom of the workbench 100, and both sides of the bottom of the support frame 110 slide on the optical axes 120 respectively. The optical axes 120 provide a low-friction sliding path, enabling the support frame 110 to move smoothly. The purpose is to ensure that before the box body is placed on the first lifting mechanism 200 of the support frame 110, the required space can be adjusted by moving the position, avoiding inconvenient placement of the box body due to space limitations. The first lifting mechanism 200 is connected to the top of the support frame 110, and the first lifting mechanism 200 is responsible for lifting the box body to the height required for welding to adapt to the operation of the welding gun 440.

[0036] Before placing the box body, evaluate the required space according to the size and shape of the box body. The operator moves the support frame 110 to slide it along the optical axes 120 to a suitable position, reserving sufficient space for the placement of the box body. After the support frame 110 is adjusted to a suitable position, the box body is placed on the support frame 110.

[0037] Further, limiting arms 130 are provided on both sides of the bottom of the workbench 100 corresponding to both sides of the support frame 110, and magnetic members are provided at the ends of the limiting arms 130 and are in contact with the back surface of the support frame 110.

[0038] The position where the limiting arms 130 contact the support frame 110 is consistent with the position of the corresponding frame edge groove 140 of the box body. This design ensures the accurate alignment of the position of the box body on the support frame with the welding path of the welding mechanism 400. The magnetic members at the ends of the limiting arms 130 provide a simple and effective fixing method, ensuring the stability of the support frame 110 during the welding process through magnetic force.

[0039] Before welding, the box body is placed on the support frame 110. The support frame 110 is fixed on the workbench 100 through the magnetic members of the limiting arms 130, and the position of the magnetic members is consistent with the position of the corresponding frame edge groove 140 of the box body. The limiting arms 130 ensure the accurate position of the support frame 110, aligning the box body with the frame edge groove 140 and providing an accurate reference for the welding path of the welding mechanism 400. Further, the first lifting mechanism 200 includes a first push rod 210 and a first telescopic guide post 230 arranged in parallel therewith. The top of the first push rod 210 and the first telescopic guide post 230 are connected to provide a first lifting block 220; the top of the first lifting block 220 is acute-angled.

[0040] Further, it further includes a second lifting mechanism 300. One side of the bottom of the workbench 100 is provided with a support plate 150, and the second lifting mechanism 300 is installed on the support plate 150. The second lifting mechanism 300 is located at the side of the first lifting mechanism 200. A plurality of openings (not marked in the figure) are provided on the frame edge groove 140 corresponding to the second lifting mechanism 300, and the purpose of the openings is to adapt to a box body with a protruding frame.

[0041] According to whether the box body has a protruding frame, select a suitable frame edge groove 140 and place it on the second lifting mechanism 300 or the first lifting mechanism 200. If the box body has a protruding frame, it is adapted to the frame edge groove 140 and the openings through the lifting of the second lifting mechanism 300, and these openings can adapt to the protruding part of the box body.

[0042] Further, the second lifting mechanism 300 includes a second push rod 310 and a second telescopic guide post 330 arranged in parallel therewith. The top of the second push rod 310 and the second telescopic guide post 330 are connected to a second lifting block 320; the top of the second lifting block 320 is acute-angled.

[0043] The second push rod 310, as a part of the second lifting mechanism 300, is used to push the second lifting block 320 to move upward to achieve the lifting function. The second telescopic guide post 330 is arranged in parallel with the second push rod 310, and the second telescopic guide post 330 provides a guiding function to ensure the stability and linear motion of the second push rod 310 during the lifting process. The second lifting block 320 is connected to the tops of the second push rod 310 and the second telescopic guide post 330, and the second lifting block 320 is in direct contact with the box body to achieve the lifting action. The top of the second lifting block 320 is designed to be acute-angled, and this design helps to adapt to box bodies of different shapes, especially those corner or edge parts that require precise lifting.

[0044] The second push rod 310 and the second telescopic guide post 330 work together to ensure the smoothness and precision of the lifting process. First, place the box body on the workbench 100 to ensure the correct position of the box body, especially for those box bodies with a protruding frame. The second lifting mechanism 300 is ready for the lifting operation, and the second push rod 310 and the second telescopic guide post 330 are in a standby state. Start the second lifting mechanism 300, and the second push rod 310 pushes the second lifting block 320 to move upward to lift the box body to the required height. The second telescopic guide post 330 ensures the linear motion and stability during the lifting process. The acute-angled design of the second lifting block 320 enables it to precisely lift the inner frame position of the box body.

[0045] Further, guide strips 160 corresponding to both sides of the bottom of the frame edge groove 140 are provided at the bottom of the workbench 100, and the guide strips 160 are wedge-shaped.

[0046] The guiding bars 160 are arranged at the bottom of the workbench 100, corresponding to both sides at the bottom of the frame edge groove 140. The guiding bars 160 are used to guide and stabilize the positioning of the box before welding. The guiding bars 160 are wedge-shaped, and this design helps to adapt to boxes of different thicknesses or shapes, ensuring the stable placement of the box on the support frame 110.

[0047] The guiding bars 160 on the workbench 100 provide a physical guide to help the operator correctly place the box. The guiding bars 160 are correspondingly arranged on both sides at the bottom of the frame edge groove 140. These guiding bars work in cooperation with the frame edge groove to ensure the precise positioning of the box before welding. The wedge-shaped guiding bars 160 can fit the bottom edge of the box, providing stable support and positioning for the box.

[0048] Before welding, the operator is ready to place the box on the second lifting mechanism 300 or the first lifting mechanism 200. The first lifting mechanism 200 or the second lifting mechanism 300 is started as needed to lift the box to an appropriate welding height. The frame of the box is aligned with the wedge-shaped guiding bars 160, so that the guiding bars 160 guide the box to the correct position and align it with the frame edge groove 140. After the frame of the box corresponds to the frame edge groove 140, the wedge-shaped guiding bars 160 help to stabilize the box and prevent displacement during the welding process.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
