[0001] The utility model relates to the technical field of laser welding, in particular to a double-head laser welding machine for backplates. Background Art

[0002] When processing the TV backplate, in the early stage, it is formed by stamping with multiple punching presses. The splicing parts (two corner positions) at the top of the backplate after stamping need to be welded to form the TV backplate into one body. Most of the existing welding methods use robots for welding. First, one corner is welded, and then the other corner is welded. However, the welding cost using robots is high, it occupies a large position space, it is difficult to adapt to welding different specifications of backplates, and the welding efficiency is low at the same time.

[0003] In order to solve the above problems, a laser welding machine dedicated to TV backplates is disclosed in the prior art.

[0030] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. In addition, it should also be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, mechanisms and / or their combinations.

[0031] Term explanation:

[0032] A linear module, also known as a linear guide system or a linear motion module, is a mechanical component used to achieve linear motion. It is widely used in fields such as automation equipment, robots, conveyor systems, and precision positioning platforms to achieve precisely controlled linear motion. A linear module includes a guide rail, a slider, a bearing, and a driving element, etc. The driving element transmits power to the slider through a connecting piece, enabling the slider to move linearly along the guide rail. Since rolling elements are installed inside the slider, low-friction and high-precision linear motion can be achieved.

[0033] Such as Figure 1 、 Figure 2As shown in the figure, in an embodiment of the present utility model, a backplane double-head laser welding machine device is proposed, including: a workbench 1, a linear module, and a welding head. The linear module includes an X-axis linear module 201, a Y-axis linear module 203, and a Z-axis linear module 202;

[0034] The X-axis linear module 201 is fixedly installed on the workbench 1. The Z-axis linear module 202 is slidably installed on the X-axis linear module 201 along the X-axis, and the Z-axis linear module 202 can rotate relative to the X-axis linear module 201 in the horizontal plane. The Y-axis linear module 203 is slidably installed on the Z-axis linear module 202 along the Z-axis, and the welding head is slidably installed on the Y-axis linear module 203 along the Y-axis, and the welding head can rotate relative to the Y-axis linear module 203 in the vertical plane.

[0035] A linear module is arranged on the workbench 1 of this welding machine device for installing the welding head, and precise positioning of the welding head in space is achieved through the coordinated work of the three groups of linear modules. Moreover, the Z-axis linear module 202 can rotate relative to the X-axis linear module 201 in the horizontal plane, and the welding head can rotate relative to the Y-axis linear module 203 in the vertical plane. Therefore, when welding the workpiece backplane 100, by rotating the Z-axis linear module 202, the welding head can be arranged along the extension line of the splicing direction of the workpiece backplane 100, rather than being parallel to one side of the workpiece backplane 100. At the same time, through the vertical arrangement of the welding head, the welding head forms a predetermined angle with the horizontal plane. Therefore, by rotating the Y-axis linear module 203 and the welding head, the welding head forms the best welding angle with the corner weld, ensuring the welding quality.

[0036] As Figure 3 shown, in this embodiment, a transfer plate 2011 capable of sliding along the X-axis is arranged on the X-axis linear module 201. The transfer plate 2011 is usually designed as a rectangular slider to achieve smooth sliding. A fixing frame 2021 is arranged at the bottom of the Z-axis linear module 202. The fixing frame 2021 is designed as a circular plate member, and multiple arc-shaped grooves are arranged thereon. These arc-shaped grooves are used to connect with the transfer plate 2011 and are usually fixed by screws. Among them, the rotation structure of the welding head can also adopt the above structure. Of course, it can be understood that the welding head can also be fixed on the connecting shaft sleeve 402, and the connecting shaft sleeve 402 is rotatably installed on the clamping seat 401, as long as the rotation of the welding head in the vertical plane can be achieved.

[0037] As Figure 1 、 Figure 2As shown in the figure, in this embodiment, two linear modules and two welding heads are arranged on the workbench 1 to achieve the function of double-head simultaneous welding. The first linear module 2 and the second linear module 3 are installed on the same side of the workbench 1, while the first welding head 4 and the second welding head 5 are respectively installed on the corresponding linear modules. The designs of the first linear module 2 and the second linear module 3 need to consider the symmetry of the equipment and the coordination of operations to achieve the high efficiency and consistency of double-head welding. The installations of the first welding head 4 and the second welding head 5 need to ensure that they can operate independently and work together simultaneously to meet the welding requirements of backplates with different shapes and sizes.

[0038] As Figure 4 shown in the figure, in this embodiment, a slide plate mechanism for installing the workpiece backplate 100 is installed on the workbench 1. The slide plate mechanism includes a first X-axis slide plate 6 and a second X-axis slide plate 7 that can move along the X axis, guided by the first X-axis guide rail 101 and the second X-axis guide rail 102, and driven by the first X-axis lead screw 104 and the second X-axis lead screw 103. It also includes a first Y-axis slide plate 8, a second Y-axis slide plate 9, a third Y-axis slide plate 10, and a fourth Y-axis slide plate 11 that can slide along the Y axis. Guided by the first Y-axis guide rail 601 and the second Y-axis guide rail 701, driven by the first Y-axis lead screw 602, the second Y-axis lead screw 603, the third Y-axis lead screw 702, and the fourth Y-axis lead screw 703, and locked by the lead screw locking seat 604.

[0039] In this embodiment, the clamping mechanism, the positioning seat, and the pushing mechanism have similar structures, only with differences in direction. The clamping mechanism includes a cylinder, a pressing plate, and a support rod. Among them, the middle of the pressing plate is rotatably installed on the support rod, the outer end of the pressing plate is installed on the piston rod of the cylinder, and the inner end of the pressing plate passes through the groove in the middle of the convex plate on the positioning seat and can be pressed against the workpiece backplate 100. The design of the clamping mechanism needs to consider the fixing stability of the workpiece backplate 100, and the selection of the cylinder needs to meet the requirements of the clamping force. The design of the convex plate and the groove on the positioning seat ensures the accurate positioning of the workpiece backplate 100 and the effective operation of the clamping mechanism. The pushing mechanism is used to push the workpiece backplate 100 to move, including a cylinder and a push plate. The design of the pushing mechanism needs to consider the magnitude and direction of the pushing force to adapt to the moving requirements of the workpiece backplate 100.

[0040] As Figure 5As shown, in this embodiment, a first clamping mechanism 801 and a second clamping mechanism 802 perpendicular to each other, as well as a first positioning seat 803 and a second positioning seat 804 perpendicular to each other, are installed on the first Y-axis slide plate 8. This design allows the workpiece backplane 100 to be clamped and positioned simultaneously in the X-axis and Y-axis directions, improving the accuracy and stability of welding. Among them, the perpendicular layout of the first clamping mechanism 801 and the second clamping mechanism 802 provides clamping forces in the X-axis and Y-axis directions, ensuring the stability of the workpiece backplane 100 during the welding process. The perpendicular layout of the first positioning seat 803 and the second positioning seat 804 ensures the precise positioning of the workpiece backplane 100 in two directions.

[0041] As Figure 6 shown, in this embodiment, a first pushing mechanism 901 and a third positioning seat 902 are installed on the second Y-axis slide plate 9. The push plate of the first pushing mechanism 901 faces the first positioning seat 803, and the third positioning seat 902 is parallel to the second positioning seat 804 to ensure the two-point positioning accuracy of the workpiece backplane 100 during movement.

[0042] As Figure 7 shown, in this embodiment, a second pushing mechanism 1002, a fourth positioning seat 1003, and a third clamping mechanism 1001 are installed on the third Y-axis slide plate 10. The second pushing mechanism 1002 faces the second positioning seat 804, the fourth positioning seat 1003 is parallel to the first positioning seat 803, and the third clamping mechanism 1001 is located on the back side of the fourth positioning seat 1003.

[0043] The design of the second pushing mechanism 1002 needs to cooperate with the second positioning seat 804 to achieve the pushing and positioning of the workpiece backplane 100. The design of the fourth positioning seat 1003 is parallel to the first positioning seat 803 to maintain the positioning consistency of the workpiece backplane 100 during movement.

[0044] As Figure 8 shown, in this embodiment, a third pushing mechanism 1101 and a fourth pushing mechanism 1102 are provided on the fourth Y-axis slide plate 11. The third pushing mechanism 1101 faces the fourth positioning seat 1003, and the fourth pushing mechanism 1102 faces the third positioning seat 902. The designs of the third pushing mechanism 1101 and the fourth pushing mechanism 1102 take into account their cooperation with the corresponding positioning seats to achieve the effective pushing and precise positioning of the workpiece backplane 100.

[0045] In this embodiment, the welding machine equipment further includes a control and monitoring system 12 and a water chiller 13. The control and monitoring system 12 is installed on the front workbench surface of the workbench 1 for real-time monitoring of the welding effect and equipment status. The water chiller 13 is installed on one side of the workbench 1 for cooling the welding head and related components to ensure the stability of the welding process and the safe operation of the equipment.

[0046] In summary, the backplane double - head laser welding machine of this embodiment includes: a workbench 1, two sets of laser welding heads, two sets of XYZ linear modules, two sets of X - axis T - type lead screw adjustment slide mechanisms, four sets of Y - axis T - type lead screw adjustment slide mechanisms, four sets of clamping and positioning mechanisms respectively installed on the Y - axis adjustment slides, a control and monitoring system 12, and a water chiller 13. It improves the problems of high welding cost, large occupied space, difficulty in adapting to different - sized backplane welding, and low welding efficiency when using robots, and can also visually monitor the welding process.

[0047] The usage process of this welding machine equipment:

[0048] When the backplane double - head laser welding machine is running, according to the specification size in the length direction of the TV backplane, manually rotate the handwheels installed on the first X - axis lead screw 104 and the second X - axis lead screw 103 to drive the nuts on the T - type lead screws to rotate, driving the first X - axis slide 6 and the second X - axis slide 7 connected to the T - type nuts to move left or right along the X - axis direction. After adjusting the distance between the positioning seats on the second Y - axis slide 9 and the fourth Y - axis slide 11 to meet the workpiece online positioning gap, respectively lock the locking seats on the handwheel sides of the first X - axis lead screw 104 and the second X - axis lead screw 103 to avoid deviation in the distance between the positioning seats on the second Y - axis slide 9 and the fourth Y - axis slide 11.

[0049] Manually rotate the handwheels installed on the first Y - axis lead screw 602 and the third Y - axis lead screw 702 to drive the nuts on the first Y - axis lead screw 602 and the third Y - axis lead screw 702 to rotate, driving the first Y - axis slide 8 and the third Y - axis slide 10 to move forward or backward along the Y - axis direction, ensuring that the positioning seats installed on the first Y - axis slide 8 and the third Y - axis slide 10 are coplanar and parallel to the first X - axis guide rail 101. After the adjustment is completed, respectively lock the locking seats on the handwheel sides of the first Y - axis lead screw 602 and the third Y - axis lead screw 702 to avoid deviation in the distance between the positioning seats on the first Y - axis slide 8 and the third Y - axis slide 10.

[0050] According to the size in the width direction of the TV backplane, manually rotate the handwheels installed on the second Y - axis lead screw 603 and the fourth Y - axis lead screw 703 to drive the nuts on the second Y - axis lead screw 603 and the fourth Y - axis lead screw 703 to rotate, driving the second Y - axis slide 9 and the fourth Y - axis slide 11 to move forward or backward along the Y - axis direction, adjusting the distance between the positioning seats on the second Y - axis slide 9 and the fourth Y - axis slide 11 to meet the workpiece online positioning gap, and ensuring that the positioning seats installed on the second Y - axis slide 9 and the fourth Y - axis slide 11 are coplanar and parallel to the linear guide rail, the first X - axis guide rail 101. After the adjustment is completed, respectively lock the lead screw locking seats 604 on the handwheel sides of the second Y - axis lead screw 603 and the fourth Y - axis lead screw 703 to avoid deviation of the Y - axis slides; after the adjustment is completed, it can meet the rapid positioning and locking of the workpiece, ensure the consistent positioning of the workpiece, and improve the product quality stability and the finished product rate.

[0051] After the tooling positioning adjustment is completed, when the equipment is running, the moving manipulator moves the workpiece above the tooling positioning of the double-head laser welding machine for the backplane. After the workpiece is placed, the moving manipulator resets.

[0052] The first pushing mechanisms 901 and the third pushing mechanisms 1101 installed on the second Y-axis slide plate 9 and the fourth Y-axis slide plate 11 simultaneously push the workpiece to the side of the positioning seats installed on the first Y-axis slide plate 8 and the third Y-axis slide plate 10. The second pushing mechanisms 1002 and the fourth pushing mechanisms 1102 installed on the third Y-axis slide plate 10 and the fourth Y-axis slide plate 11 push the workpiece to the welding position on the side of the positioning seats of the first Y-axis slide plate 8 and the third Y-axis slide plate 10 to complete the workpiece positioning.

[0053] The first clamping mechanisms 801, the second clamping mechanisms 802, and the third clamping mechanisms 1001 installed on the first Y-axis slide plate 8 and the third Y-axis slide plate 10 synchronously complete the workpiece clamping.

[0054] According to the positioning position of the motor backplane after the adjustment is completed, manually adjust the installation connection angles of the fixing frames 2021 of the Z-axis linear module 202 and the adapter plates 2011 connected to the sliders of the X-axis linear module 201 respectively, so as to ensure the angle between the welding head and the welding position of the workpiece, and avoid too large or too small an angle between the welding head and the workpiece during welding, resulting in over-welding or lack of welding on both sides of the weld.

[0055] Manually rotate the runner 2031 of the Y-axis linear module 203 to adjust the gap between the welding head and the workpiece within the laser light output range of the welding head. The welding head can be adjusted along the Z-axis on the workpiece clamping seat 401 of the Y-axis linear module 203. Adjust the welding connection bushing 402 to rotate upward or downward along the Z-axis. After adjusting the angle of the welding head, lock the welding head clamping to ensure the welding angle between the welding head and the workpiece and ensure the welding quality of the weld.

[0056] After the workpiece positioning is completed, two sets of welding heads arranged on both sides of the workpiece synchronously complete the workpiece welding operation. The welding process is synchronously displayed on the monitoring display screen. This equipment improves the problems of high welding cost, large occupied position space, difficulty in adapting to the welding of backplanes of different specifications, and low welding efficiency when using robots, and can also visually monitor the welding process.

[0057] Although the specific implementation manners of the present invention are described above in conjunction with the drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the present invention.
