Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, please refer to Figures 1-5 and Figures 7-9 The present invention provides a technical solution: a workstation adjustable battery box welding device, including a bed 100, a slide 101 fixedly connected to the top of the bed 100, a welding gun 102 connected to the outer wall of the slide 101 via a screw drive, a support platform 103 fixedly connected to the outer wall of the bed 100, and an adsorption mechanism 200 provided at the bottom of the welding gun 102.

[0035] In the process of adjusting the position of the battery box panel in the adjustable-station battery box welding device, the battery box panel is affected by the weld tension during the welding process, which can easily cause the weld seam of the panel to tilt, increasing the welding difficulty of the battery box and resulting in the dimensions of the welded box not meeting the standard. Therefore, an adsorption mechanism 200 is set up to drive the battery box panel to adjust its position and adjust the weld seam spacing of the battery box panel, so that the weld seam spacing is consistent during the welding process, increasing the stability of the battery box panel welding. At the same time, a laser sensor 104 is set up to detect the weld seam gap to prevent the weld seam from tilting and causing the dimensions of the welded box to not meet the standard, thus increasing the stability of the adjustable-station battery box welding device in welding the battery box panel. In addition, the adsorption mechanism 200 supports the battery box panel during the welding process to prevent the battery box panel from being affected by the weld tension during the welding process, which could cause the weld seam of the battery box panel to tilt and affect the dimensions of the welded battery box, thus increasing the stability of the battery box welding device in welding the battery box panel.

[0036] The adsorption mechanism 200 includes an adsorption platform 201, with a gasket 202 fixedly connected to the outer wall of the adsorption platform 201. A communicating cavity 206 is formed on the inner wall of the adsorption platform 201, communicating with the inside of the gasket 202. The gasket 202 is used to adsorb the battery box panel. A guide tube 205 is covered and connected to the inner wall of the adsorption platform 201, communicating with the inside of the communicating cavity 206. The adsorption platform 201 is used to adjust the angle of the battery box panel. A support block 204 is fixedly connected to the inner wall of the adsorption platform 201. 4. Support block 204 protrudes from the outer wall of adsorption platform 201 and is located on the same horizontal plane as gasket 202. The outer wall of support block 204 is corrugated to increase friction with battery box panel. Pressure sensor 203 is fixedly connected to the inner wall of adsorption platform 201 to detect the pressure of support block 204 on battery box panel. Laser sensor 104 is fixedly connected to the inner wall of support platform 203 to detect weld width. Welding gun 10 2. Position adjustment is achieved by rotating the lead screw driven by a servo motor mounted on the outer wall of the slide 101. The axis of the welding gun 102 and the axis of the support table 103 are located in the same vertical plane. A vacuum pump is installed inside the bed 100 and connected to the guide tube 205 to evacuate the inside of the connecting cavity 206. An adjustment mechanism 300 is provided on the outer wall of the adsorption table 201. The adjustment mechanism 300 includes an adjustment table 303. A cylinder 2 305 is fixedly connected to the outer wall of the adjustment table 303. The output end of the cylinder 2 305 passes through the outer wall of the adjustment table 303 and is connected to the adsorption table 201. The inner wall of the auxiliary platform 201 is hinged, and the outer wall of the guide tube 205 is slidably connected to the inner wall of the adjustment platform 303. The guide tube 205 is used to guide the adsorption platform 201. The outer wall of the adjustment platform 303 is slidably connected to the adjustment motor 306 via a guide rail. The output end of the adjustment motor 306 is threaded to the inner wall of the adjustment rod 307 via a lead screw. The outer wall of the adjustment rod 307 is rotatably connected to the outer wall of the adsorption platform 201 via a rotating shaft. The adjustment motor 306 is used to drive the adjustment rod 307 to make the adsorption platform 201 swing and adjust the angle.

[0037] When the adjustable battery box welding device is put into use, the battery box plate is placed on the outer wall of the adsorption table 201. The vacuum pump inside the bed 100 is activated to evacuate the connecting cavity 206. After the battery box plate is adsorbed by the gasket 202, the cylinder 305 is activated to drive the adsorption table 201 to adjust the battery box plate towards the support table 103, so that the battery box plate contacts the outer wall of the support table 103. If the battery box plate contacts the outer wall of the support table 103 while tilted, the battery box plate... The battery box plate is attracted and supported by the support block 204 through the gasket 202. After contacting the outer wall of the support platform 103, the pressure sensor 203 generates a pressure change and provides feedback, which activates the regulating motor 206 to drive the regulating rod 307 to rotate the adsorption platform 201. This adjusts the angle of the battery box plate, ensuring that the adsorption platform 201 keeps the battery box plate parallel to the inclined surface of the outer wall of the support platform 103. During the adjustment process, the regulating rod 307 tilts with the adsorption platform 201, driving the regulating motor 206 in the opposite direction. The outer wall of the adjustment platform 303 slides, and the battery box panel and the support platform 103 maintain parallel contact. After the pressure on the pressure sensor 203 is kept consistent, the slide 101 is activated to drive the welding gun 102 to weld the battery box panel. During the welding process, the battery box panel is supported by the support platform 103, so that the battery box panel is kept perpendicular to each other during welding. During the adjustment process, the weld gap is detected by the laser sensor 104 to prevent the weld from tilting and causing the dimensions of the box to not meet the standard after welding. When the weld point generates tension on the battery box panel during the welding process, the battery box panel is supported by the support platform 103. At the same time, the support block 204 and the washer 202 squeeze and support the battery box panel to prevent the battery box panel from tilting due to the weld point tension during the welding process. At the same time, the support block 204 with the corrugated outer wall contacts the outer wall of the battery box panel, increasing the friction between the support block 204 and the battery box panel to prevent the battery box panel from tilting due to the weld point tension during the welding process.

[0038] Example 2, based on Example 1, please refer to... Figure 6The present invention provides the following technical solution: the outer wall of the adjustment table 303 is hinged to the output end of the cylinder 302, the outer wall of the cylinder 302 is slidably connected to the inner wall of the support table 301 via a slide rail, the outer wall of the support table 301 is fixedly connected to the outer wall of the bed 100, the cylinder 302 is used to drive the adjustment table 303 to adjust its position, the inner wall of the support table 301 is fixedly connected to the adjustment motor 304, the output end of the adjustment motor 304 is threadedly connected to the inner wall of the cylinder 302 via a lead screw, the adjustment motor 304 is used to drive the cylinder 302 to adjust its position, the cylinder 305 is used to drive the adsorption table 201 to bring the battery box plate into contact with the outer wall of the support table 103, the number of laser sensors 104 is two sets, the two sets of laser sensors 104 are symmetrically arranged on both sides of the inner wall of the support table 103 with the center line of the support table 103 as the axis of symmetry, the two sets of laser sensors 104 are used to detect the weld seam of the battery box plate to keep the weld seam spacing on both sides of the battery box plate consistent;

[0039] In the process of adjusting the position of the battery box panel in the adjustable battery box welding device, the battery box panel is affected by the weld tension during the welding process, which can easily cause the weld seam of the panel to tilt, increasing the welding difficulty of the battery box and resulting in the box size not meeting the standard after welding. Therefore, an adjustment mechanism 300 is set to adjust the battery box panel to prevent the battery box panel from tilting, which would lead to inconsistent weld seam spacing and increase the stability of the battery box welding device in welding the battery box panel. At the same time, the adjustment mechanism 300 can make fine adjustments during the welding process of the battery box panel to prevent the battery box panel from tilting due to the weld tension, which would lead to inconsistent weld seam spacing and increase the stability of the battery box welding device in welding the battery box panel.

[0040] When the laser sensor 104 detects that the weld seams of the battery box panel are parallel and the weld seam spacing is large, the laser sensor 104 provides feedback and activates cylinder 302. The adjusting motor 304 remains stationary, allowing the output of cylinder 302 to drive the adjusting platform 303 for position adjustment. The adjusting platform 303, through the guide tube 205 and cylinder 305, limits the adsorption platform 201, causing the battery box panel to be driven by the adsorption platform 201 and maintaining parallelism with the outer wall of the support platform 103 to adjust the weld seam spacing. When the laser sensor 104 detects that the battery box panel weld seams are tilted, the laser sensor 104 provides feedback and activates cylinder 302 simultaneously, activating the adjusting motor 304 for synchronous action. The adjusting motor 304 drives cylinder 302 to slide on the outer wall of the support platform 201. Simultaneously, cylinder 302 extends and connects to the outer wall of the adjusting platform 303 via a hinge, allowing the adjusting platform 303 to move. The stage 303 tilts, and the guide tube 205 and cylinder 2 305 are limited by the adjustment stage 303, causing the adsorption stage 201 and the adjustment stage 303 to tilt synchronously. This allows the adsorption stage 201 to keep the battery box plate parallel to the outer wall of the support stage 103 while swinging on the outer wall of the support stage 103 to correct the tilted weld. This ensures that the weld is kept parallel during welding of the battery box plate. When the battery box plate tilts due to the tension of the weld point during welding, the laser sensor 104 detects the weld and provides feedback, activating cylinder 1 302 and simultaneously starting the adjustment motor 1 304 to move synchronously, causing the adjustment stage 303 to tilt. The adjustment stage 303 is limited by the guide tube 205 and cylinder 2 305, causing the adsorption stage 201 and the adjustment stage 303 to tilt synchronously. This allows the adsorption stage 201 to correct the tilted weld during the welding heating process of the battery box plate, reducing the slope of the battery box plate weld.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended technical solutions and their equivalents.
