Furthermore, the terms "first," "second," etc., are used only for descriptive distinction and should not be construed as indicating or implying relative importance. All electrical components mentioned in this document are electrically connected to an external main controller and 220V AC mains power, and the main controller can be a conventionally known device such as a computer that provides control.

[0028] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use.

Therefore, they should not be construed as limitations on this utility model.

[0029] like Figures 1-8As shown, this utility model provides a technical solution: a laser welding method for making signs and labels, including a worktable 1, which is used to accommodate and place signs and labels. A frame 101 is provided on one side of the top of the worktable 1, and a welding head 102 is provided on the frame 101. The frame 101 provides an installation environment for the welding head 102. During welding operations, the frame 101 can drive the welding head 102 to move in three directions: X-axis, Y-axis, and Z-axis, thereby assisting the welding head 102 in welding operations. Welding operations by the welding head 102 along the X, Y, and Z axes are existing technologies and will not be described in detail here. A displacement component 2 is provided at the top of the worktable 1 and is used to adjust the distance between the support rods 206 to accommodate signs and labels of different widths. A rotation component 3 is provided on one side of the support rods 206 and is used to drive the vertical rod 402 to rotate, thereby adjusting the angle of the signs and labels. A fixing component 4 is provided between the support rods 206 and is used to clamp the signs and labels and can accommodate signs and labels of different heights.

[0030] like Figure 1-8As shown in the embodiment of this application, the fixing component 4 includes a vertical rod 402 located on one side of the support rod 206. A long spring 403 is provided inside the vertical rod 402, with both ends of the long spring 403 connected to the limiting block 404. A sliding rod 405 is provided at the other end of the limiting block 404. One end of the sliding rod 405 passes through the vertical rod 402 to the outside and is connected to the horizontal rod 401. Specifically, during the welding operation of the sign, the position of the horizontal rods 401 is adjusted to accommodate signs of different heights. When the position of the horizontal rod 401 is adjusted, the long spring... Spring 403 will deform, and the deformation force of the long spring 403 will act on the signboard through the groove 407 on the crossbar 401. When the long spring 403 is in its original state, the distance between the crossbars 401 can meet the minimum height of the signboard to be welded. When the long spring 403 is in its maximum deformation, it can meet the maximum height of the signboard to be welded. When adjusting the distance between the crossbars 401, the worker will pull the crossbar 401 to move it horizontally. During the horizontal movement of the crossbar 401, the sliding rod 40 will be driven. 5. The slide bar 405 moves horizontally along the groove inside the vertical rod 402. The slide bar 405 is fixedly connected to the limiting block 404, and the outer wall of the limiting block 404 is in contact with the groove. Therefore, during the movement, the slide bar 405 will cause the long spring 403 to deform through the limiting block 404. The deformation force generated by the long spring 403 will squeeze the sign to fix the sign. The limiting block 404 can limit the displacement distance of the slide bar 405. It should be noted that both ends of the long spring 403 are fixedly connected to the limiting block 404, and the long spring 403 is in the vertical position. The vertical rod 402 is located in the inner circular groove in the middle, while the limiting block 404 is partially located in the circular groove and partially located in the sliding grooves at both ends of the vertical rod 402. Since the size of the sliding groove is larger than that of the circular groove, the limiting block 404 can ensure that the long spring 403 is completely located in the circular groove of the vertical rod 402 when it is in the normal state. Therefore, the limiting block 404 can not only limit the displacement distance of the sliding rod 405, but also suspend the long spring 403 in the circular groove of the vertical rod 402 to ensure that the distance between the horizontal bar 401 at both ends of the vertical rod 402 and the middle part of the vertical rod 402 is equal.

[0031] like Figure 1-8As shown in the embodiment of this application, both the vertical rod 402 and the horizontal rod 401 have a groove 407 on one side. Several fixing cylinders 409 are provided on the inner wall of the groove 407. A clamping plate 406 is provided at one end of each fixing cylinder 409, and a short spring 408 is provided inside it. Specifically, because the groove 407 is too wide, a clamping plate 406 is provided inside the groove 407 to further fix the sign and prevent it from tilting inside the groove 407, thus avoiding any impact on the welding accuracy. When fixing the sign, adjust the distance between the crossbars 401. Once a suitable distance is reached, align the edge of the sign with the center of the clamping plate 406, and then release the crossbars 401. While fixing the sign, the crossbars 401 will push the sign into the groove 407. During this pushing process, the clamping plate 406 will press against the inner wall of the groove 407, thereby causing the fixing cylinder 409 to move horizontally along the circular groove within the groove 407. During the translation of the fixed cylinder 409, the short spring 408 will be compressed simultaneously. The deformation force generated by the compression of the short spring 408 will act on the clamping plate 406, thereby fixing the sign. By setting the clamping plate 406, it can adapt to the fixing of signs of different thicknesses. It should be noted that when fixing the sign, the side to be welded should be exposed on the outside of the horizontal bar 401 so that the sign can be aligned for welding. The grooves 407 on the horizontal bar 401 and the vertical bar 402 are through-type. When fixing the sign, the sign first contacts the clamping plate 406 in the horizontal bar 401. If the sign is long enough, it is pushed towards the groove 407 in the vertical bar 402 so that it contacts the clamping plate 406 in the vertical bar 402. If the sign is short enough, it does not need to be fixed by the clamping plate 406 in the vertical bar 402. When fixing the sign, it is essential to ensure that the welding edge is exposed on the outside.

[0032] like Figure 1-8As shown in the embodiment of this application, the displacement component 2 includes a base 202, which is located on both sides of the top of the workbench 1. A screw 201 is provided on the inner side of the base 202, and a threaded seat 203 is provided on the outer wall of the screw 201. The bottom end of the threaded seat 203 is located in the waist-shaped groove on the upper surface of the workbench 1, and a support rod 206 is provided on its top end. A torsion ring 207 is provided on the outer wall of one end of the screw 201, and a fixing ring 205 is provided on the outer wall of the other end. The fixing ring 205 is located inside the arc-shaped seat 204, which is located in the middle of the top of the workbench 1. Specifically, after the label is fixed, the worker adjusts the distance between the support rods 206 by twisting the torsion ring 207 to align the welding edges of the label. Twisting the torsion ring 207 will drive the screw 201... 01 rotates, and the screw 201 is rotatably connected to the fixed ring 205. The fixed ring 205 is set to limit the screw 201. During the rotation of the screw 201, it will drive the threaded seat 203 to move along the waist-shaped groove on the worktable 1. The threaded seat 203 and the screw 201 are threadedly connected, and the waist-shaped groove is used to limit and guide the threaded seat 203. When the threaded seat 203 moves, it will drive the support rod 206 to move synchronously, thereby adjusting the distance between the support rods 206 so that the welding part of the sign is connected. The arc-shaped seat 204 is set to separate the screw 201, so that the screws 201 on both sides do not interfere with each other and move independently to adapt to the welding operation of two signs with different widths.

[0033] like Figure 1-8As shown in the embodiment of this application, the rotating component 3 includes a lock head 302, which is located on one side of the support rod 206 and cooperates with the stop groove 306 on the surface of the support rod 206. A toothed ring 303 is engaged with the inner wall of the lock head 302. A rotating shaft 301 is provided on the inner wall of the toothed ring 303. A limit ring 305 is provided on the outer wall of one end of the rotating shaft 301. A sealing cylinder 304 is provided between the limit ring 305 and the toothed ring 303. Specifically, when performing the welding operation of the sign, the vertical rod 402 is rotated by the rotating shaft 301, which can adjust the angle of the sign, thereby welding different sides of the sign. When adjusting the angle, the lock head 302 engages with the toothed ring 303, driving the toothed ring 303 to rotate. The toothed ring 303 and the rotating shaft 301... The two are fixedly connected, which can drive the rotating shaft 301 to rotate to adjust the angle of the sign. After adjusting to the appropriate position, the limiting ring 305 is removed. The limiting ring 305 and the rotating shaft 301 are threadedly connected. The outer wall of the rotating shaft 301 is provided with a threaded groove that matches the thread on the inner wall of the limiting ring 305. After the limiting ring 305 is removed, the locking head 302 is removed. Then the locking head 302 is aligned with the stop groove 306 and inserted along the toothed ring 303. The toothed ring 303 and the stop groove 306 are both adapted to the locking head 302. During the process of the locking head 302 being inserted into the stop groove 306, the toothed ring 303 and the locking head 302 can still maintain a meshing connection. The sealing cylinder 304 is used to limit the movement distance of the limiting ring 305. The limiting ring 305 can limit the locking head 302.

[0034] The working principle of this utility model is as follows:

[0035] During the welding of signs, the distance between the crossbars 401 is first adjusted to accommodate signs of different heights. When the distance between the crossbars 401 changes, the sliding rod 405 will cause the limiting block 404 to move horizontally. During this movement, the limiting block 404 causes the long spring 403 to deform. The deformation force of the long spring 403 acts on the crossbars 401, initially fixing the signs. After the signs enter the crossbars 401, they will press against the clamping plate 406. This pressure causes the fixing cylinder 409 to move horizontally. During this movement, the fixing cylinder 409 will compress the short spring 408, causing it to deform. The deformation force of the short spring 408 acts on the clamping plate 406, thus providing secondary fixation to prevent the signs from shifting into the groove 4. The 07 is tilted and can accommodate signs of different thicknesses. After the sign is fixed, rotating the torsion ring 207 drives the screw 201 to rotate. During the rotation of the screw 201, the threaded seat 203 drives the support rod 206 to move horizontally, thereby adjusting the distance between the support rods 206 to accommodate the welding of signs of different widths and to connect the welded joints. Then, the locking head 302 drives the gear ring 303 to rotate, which in turn drives the rotating shaft 301 to rotate. During the rotation of the rotating shaft 301, the vertical rod 402 will rotate, thereby adjusting the welding angle of the sign and flipping it over. It should be noted that the rotation of the screw 201 and the rotating shaft 301 should be adjusted on both sides to ensure that the welded joints remain connected during the welding process.

[0036] In summary, this utility model discloses a laser welding method for making signs and labels, including a worktable 1, a displacement component 2, which is set at the top of the worktable 1 and is used to adjust the distance between the support rods 206 to accommodate signs and labels of different widths, a rotation component 3, which is set on one side of the support rods 206 and is used to drive the vertical rod 402 to rotate, thereby adjusting the angle of the signs and labels, and a fixing component 4, which is set between the support rods 206 and is used to clamp the signs and labels and can accommodate signs and labels of different heights. This invention can adapt to signs of different heights by adjusting the distance between the crossbars 401. The clamping plate 406 can help fix the signs to prevent them from tilting in the groove 407. Adjusting the distance between the support rods 206 can adapt to signs of different widths and connect their weld joints. By using the locking head 302 to drive the rotating shaft 301 on the inner wall of the toothed ring 303 to rotate, the signs can be flipped over, thus enabling multi-sided welding of the signs and fixing them during the welding process. This ensures that the laser welding head 102 can weld accurately, improving welding quality and enhancing the versatility and applicability of the equipment.

[0037] Although embodiments of the present 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 present invention, the scope of which is defined by the appended embodiments and their equivalents.
