[0002] Liquid crystal displays (LCDs) are widely used in various fields. They typically consist of a backlight module and a glass module. Flexible printed circuit boards (FPCs) are pre-installed on both the backlight module and the glass module. During assembly, the FPCs of the two components need to be soldered together.

[0003] Existing technologies mostly use automated welding equipment when welding FPCs of both components. However, the welding process is mostly carried out by a single welding device, and manual assistance is still required for feeding and positioning. This makes it impossible to form an automated production line with upstream and downstream equipment, resulting in low production efficiency. Utility Model Content

[0038] Reference Figures 1 to 3 As shown, this application proposes a welding device for display screen FPC cables, comprising:

[0039] The machine base 100 has a guide rail 200 mounted on its bearing surface;

[0040] The handling robot 300 is connected to the guide rail 200 and can move horizontally along the guide rail 200 for handling parts to be welded;

[0041] The feeding device 400 is located on the opposite side of the handling robot 300. It includes a feeding conveyor belt for conveying the workpiece to be welded, and a feeding robot 410 located on one side of the feeding conveyor belt. The feeding robot 410 is used to grab the workpiece to be welded from the feeding conveyor belt.

[0042] The calibration device 500 is located between the guide rail 200 and the feeding device 400. It is used to receive the workpiece to be welded by the feeding robot 410 and to calibrate the workpiece to be welded.

[0043] The welding device 600 is arranged at intervals with the loading robot 410. The welding device 600 includes a welding platform 610 for placing the workpiece to be welded, and a welding assembly 620 located above one side of the welding platform 610. The welding assembly 620 is used to weld the workpiece to be welded on the welding platform 610.

[0044] In this embodiment, the machine base 100 is used to support the entire welding equipment. Parallel guide rails 200 are mounted on its support surface. The guide rails 200 are arranged horizontally, extend above the support surface, and are located on the side of the support surface. The sliding surfaces of the guide rails 200 all face the inside of the machine base 100 and are equipped with sliders to fully utilize the space of the support surface for guiding the movement of the handling robot 300. A feeding device 400, a calibration device 500, and a welding device 600 are sequentially arranged on the guide rails 200 facing the inside of the machine base 100.

[0045] Multiple handling robots 300 can be installed simultaneously for handling; for example, two handling robots 300 are provided. The handling robots 300 are mounted on a slider and can reciprocate horizontally with the slider. Furthermore, the handling robots 300 can move vertically via sliding cylinders. The handling robots 300 are gripper-type or suction cup-type robots, capable of precisely controlling the handling of the parts to be welded between different workstations.

[0046] The feeding device 400 is located on the side adjacent to the guide rail 200 on the machine base 100, and includes a feeding conveyor belt and a feeding robot 410. The feeding conveyor belt extends outward from the side of the machine base 100 and is used to continuously transport the parts to be welded. The feeding robot 410 is a gripper-type or suction cup-type robot, mounted on a multi-axis moving module on the side of the feeding conveyor belt away from the guide rail 200. It allows the feeding robot 410 to move in combination to a designated position in the horizontal and vertical directions, for gripping a single part to be welded from above the feeding conveyor belt and transferring it to the calibration device 500.

[0047] The calibration device 500 is set between the feeding device 400 and the guide rail 200. It has a positioning platform. The positioning platform uses a vacuum adsorption mechanism to fix the workpiece to be welded. The position of the workpiece to be welded is calibrated in the horizontal and transverse directions by a fine adjustment mechanism.

[0048] The welding device 600 is located on the opposite side of the guide rail 200 of the machine base 100, and includes a welding platform 610 and a welding assembly 620. The welding platform 610 is used to fix the workpiece to be welded after correction, and the workpiece position can be fixed by vacuum adsorption. The welding assembly 620 is located above the welding platform 610, and its position can be adjusted by a multi-axis moving module. The welding assembly 620 can be a laser welding head 623, a thermoforming welding head, or an ultrasonic welding head, depending on the material of the workpiece to be welded and the welding requirements.

[0049] The workflow is as follows: The workpiece to be welded is conveyed to the loading position via the loading conveyor belt. The loading robot 410 picks it up and places it on the calibration device 500, driving the positioning platform for calibration. After calibration, the handling robot 300 transports the calibrated workpiece to the welding platform 610, where the welding assembly 620 automatically performs the welding operation. After welding is completed, the handling robot 300 can move the finished product to the next process.

[0050] Reference Figure 5 and Figure 7 As shown, in one embodiment, the correction device 500 includes a first vision component 510 and a correction platform 520;

[0051] The first vision component 510 is positioned between the feeding conveyor belt and the calibration platform 520;

[0052] The calibration platform 520 includes a first moving module 521, on which a placement plate 522 is connected, and a positioning member 523 located on one side of the placement plate 522 and capable of moving horizontally relative to the placement plate 522. The positioning member 523 is used to position the part to be welded.

[0053] In this embodiment, the correction device 500 further includes a first vision component 510 and a correction platform 520.

[0054] The first vision component 510 is installed between the feeding conveyor belt and the calibration platform 520. Specifically, it is a set of industrial cameras and a light source system, mounted on the bearing surface of the machine tool 100 and facing the workpiece to be welded. The first vision component 510 is used to identify the positioning marks on the workpiece to be welded in advance, and obtain its initial placement position and offset, before the workpiece to be welded is transferred from the feeding conveyor belt to the calibration platform 520 by the feeding robot 410, so as to perform subsequent calibration.

[0055] The calibration platform 520 includes a first moving module 521, a placement plate 522, and a positioning element 523. The first moving module 521 is a slide mechanism capable of lateral planar movement and optionally equipped with an θ-axis for rotational adjustment, used to drive the placement plate 522 for position adjustment. The placement plate 522 is fixedly mounted on the first moving module 521 and carries the workpiece to be welded placed by the loading robot 410, and is equipped with a vacuum suction element to stabilize the workpiece. The positioning element 523 is disposed on the first moving module 521 and is horizontally adjacent to the placement plate 522, allowing it to move relative to the placement plate 522. The positioning element 523 is typically a set of L-shaped pressure blocks or elastic claw structures, which, based on the positional deviation information provided by the first vision component 510, pushes the workpiece to be welded to a precise positioning position.

[0056] In actual operation, when the workpiece to be welded is moved, it passes above the first vision component 510, which captures its image and calculates the difference between the current coordinates and the target coordinates. Based on this command, the first moving module 521 adjusts the position of the placement plate 522, while simultaneously driving the positioning component 523 to precisely correct the workpiece to be welded. After correction, the handling robot 300 transfers it to the welding platform 610 for subsequent welding.

[0057] Reference Figure 5 As shown, in one embodiment, the calibration platform 520 further includes a flip plate 524, which is arranged horizontally parallel to the placement plate 522. One side of the flip plate 524 is connected to the rotating end of a rotary cylinder 525, and the fixed end of the rotary cylinder 525 is connected to the first moving module 521.

[0058] In this embodiment, the calibration platform 520 further includes a flipping plate 524, which is horizontally arranged and parallel to the placement plate 522 at the same height. A vacuum adsorption component is provided on the flipping plate 524 to fix the workpiece to be welded during the flipping process. The rotating end of the rotary cylinder 525 is connected to one side of the flipping plate 524, while its fixed end is mounted on a bracket on the first moving module 521. Its rotating end can rotate 180 degrees to drive the flipping plate 524 to perform the flipping action.

[0059] The working process is as follows: When the workpiece to be welded needs to be flipped, if the first vision component 510 does not detect the surface to be welded when it passes through the detection station, the loading robot 410 directly places the workpiece to be welded onto the placement plate 522 without flipping it; if the first vision component 510 detects the surface to be welded, the loading robot 410 places the workpiece to be welded onto the flipping plate 524 and fixes it with a vacuum adsorption component, and then starts the rotary cylinder 525 to rotate the flipping plate 524 180 degrees from the initial horizontal position to the flipping position above the placement plate 522, and then releases the workpiece to be welded so that it falls smoothly onto the placement plate 522, completing the flipping process of the workpiece to be welded.

[0060] Reference Figure 6 As shown, in one embodiment, the welding platform 610 includes a second moving module 611, a platform housing 612 is connected to the second moving module 611, a welding adsorption table 613 is connected to the upper front end of the platform housing 612, a welding support table 614 is provided on the inner side of the welding adsorption table 613, there is a gap between the welding support table 614 and the welding adsorption table 613, and an adjusting clamping arm 615 is provided in the gap between the welding support table 614 and the welding adsorption table 613.

[0061] In this embodiment, there are four welding platforms 610, each with the same configuration. The second moving module 611 is a sliding table structure, set on the bearing surface of the machine base 100. A platform housing 612 is connected to the sliding table of the second moving module 611 to support the various functional components of the welding station. The second moving module 611 drives the platform housing 612 to reciprocate between the handling robot 300 and the welding component 620. A welding adsorption table 613 is provided at the upper front end of the platform housing 612. The welding adsorption table 613 is used to support the workpiece to be welded. Its surface is provided with multiple vacuum adsorption elements, which firmly fix the workpiece to be welded in the welding position through negative pressure adsorption. Inside the welding adsorption table 613, a welding support table 614 is provided. The welding support table 614 is rectangular and is used to support the bottom of the welding area of ​​the FPC cable to be welded, ensuring that it does not deform or drift due to external forces during welding. The welding support table 614 is usually fixedly installed, but it can also be designed as a floating structure to absorb welding stress as needed. A narrow gap is left between the welding adsorption table 613 and the welding support table 614, and an adjusting clamping arm 615 is provided in the gap. After the FPC cable welding area is fixed, the adjusting clamping arm 615 can extend out of the gap and slightly lift or clamp the edge or pin area of ​​the FPC cable to help fix or precisely press the key solder joint area, prevent warping or displacement, and improve welding consistency and quality.

[0062] Reference Figure 6 As shown, in one embodiment, a positioning block 616 is also provided above the gap between the welding support platform 614 and the welding adsorption platform 613. The positioning block 616 is connected to the third moving module 618 through the positioning rod 617. The third moving module 618 is used to drive the positioning block 616 to rise and fall.

[0063] In this embodiment, a positioning block 616 is also provided above the gap between the welding support platform 614 and the welding adsorption platform 613 to press down the FPC cable welding area and prevent deformation and displacement during welding. The positioning block 616 is connected to the third moving module 618 through the positioning rod 617. The third moving module 618 can move in both the horizontal and vertical directions to drive the positioning block 616 to rise and fall.

[0064] Reference Figure 6 and Figure 10 As shown, in one embodiment, the adjustable clamping arm 615 includes a lifting clamping arm 615A and a fixed clamping arm 615B. The fixed clamping arm 615B is located on both sides above the lifting clamping arm 615A. The clamping ends of both the fixed clamping arm 615B and the lifting clamping arm 615A are designed to be serrated.

[0065] In this embodiment, the adjusting clamping arm 615 is connected to a lifting cylinder, which is connected to a horizontal moving module. This allows the adjusting clamping arm 615 to move closer to the FPC cable welding area during welding and to clamp and fix the FPC cable. The adjusting clamping arm 615 includes a lifting clamping arm 615A, a fixed clamping arm 615B, and a cylinder that drives the lifting clamping arm 615A to move. The lifting clamping arm 615A moves from bottom to top to lift the edge of the FPC cable from below. The fixed clamping arm 615B is fixedly disposed on both sides above the lifting clamping arm 615A, corresponding to the inner edge of the welding adsorption table 613. Its structure is a "symmetrical claw type" to achieve bidirectional clamping after the lifting clamping arm 615A rises. This adjusts the welding position of the FPC cable to ensure accurate alignment of the weld point. The clamping end faces of both the fixed clamping arm 615B and the lifting clamping arm 615A are designed with serrations to facilitate anti-slip during clamping.

[0066] Reference Figure 6 As shown, in one embodiment, the welding adsorption table 613 is rotatably connected to the platform box 612, so that it rotates relative to the welding support table 614.

[0067] In this embodiment, the welding adsorption table 613 and the platform housing 612 are rotatably connected via a rotating assembly, allowing the welding adsorption table 613 to be angled or rotated relative to the welding support table 614. The rotating assembly includes a horizontal rotating shaft disposed between the welding adsorption table 613 and the platform housing 612; a rotating shaft bracket fixed to the platform housing 612 for supporting and limiting the rotation direction; and a driving assembly, preferably a small stepper motor or a miniature rotary cylinder, for controlling the rotation angle of the welding adsorption table 613. Under the control of the driving assembly, the welding adsorption table 613 can rotate around the horizontal rotating shaft at a certain angle, forming a certain angle with the welding support table 614. For FPCs with stepped, bent, or sloping welding surfaces (such as COF-on-Glass edge pins), the rotating adsorption table can achieve close-fitting welding with its local contact surface, improving the uniformity of the weld joint.

[0068] Reference Figure 4 As shown, in one embodiment, the welding assembly 620 includes a gantry frame 621, a fourth moving module 622 is provided on the gantry frame 621, a welding head 623 is provided on the lower front side of the fourth moving module 622, and a smoke pipe 624 is provided on one side of the welding head 623. The smoke pipe 624 is connected to an air extraction device.

[0069] In this embodiment, the gantry 621 is installed on the machine base 100 on one side of the welding platform 610, and is located on the edge of the machine base 100 on the opposite side of the guide rail 200. It spans multiple welding platforms 610. The fourth moving module 622 is installed on the upper crossbeam of the gantry 621 and can move in both horizontal and vertical directions. It can be driven by a linear motor, a lead screw motor, or a slide rail module. The welding head 623 is installed on the lower front side of the fourth moving module 622 and is used for precise welding of FPC cables. It can be a laser welding head 623, a hot press welding head, a pulse hot press head, or an ultrasonic welding head, depending on the specific welding process. The welding head 623 is equipped with a height adjustment mechanism for vertical pressure or focus adjustment of FPCs of different thicknesses. The fume extractor 624 is installed on one side of the welding head 623, close to the welding area, and has a cylindrical structure. It is used to remove fumes, odors, and harmful gases in a timely manner during the welding process.

[0070] Reference Figure 4 As shown, in one embodiment, a fifth moving module 625 is also provided on the gantry 621, a second vision component 626 is connected to the fifth moving module 625, and a welding flux component 627 is provided on one side of the second vision component 626.

[0071] In this embodiment, the fifth moving module 625 is located below the fourth moving module 622 and can move laterally in the same direction as the fourth moving module 622. The second vision component 626 is fixedly mounted on the fifth moving module 625 and is used to detect whether the position of the FPC cable on the workpiece to be welded is correct before the welding component 620 welds. If it is correct, welding is performed; if it is incorrect, the workpiece to be welded is transported to the NG conveyor belt by the handling robot 300. The flux component 627 is mounted on one side of the second vision component 626 and can move laterally with the second vision component 626. It is used to locally apply flux to the welding area before welding.

[0072] Reference Figure 8 and Figure 9 As shown, in one embodiment, a discharge device 700 is also included. The discharge device 700 is located on one side of the welding device 600 and includes a defective product conveyor belt 710 and a finished product conveyor belt 720. The handling robot 300 transports the workpiece to be welded from the welding device 600 to the defective product conveyor belt 710 or the finished product conveyor belt 720.

[0073] In this embodiment, a discharge device 700 is provided on one side of the welding device 600 to achieve sorting and conveying of workpieces after welding. The discharge device 700 includes a defective product conveyor belt 710 and a finished product conveyor belt 720, which are arranged at a 90-degree angle to each other on one side of the welding platform 610 (within the working range of the handling robot 300); both are narrow belt conveyor structures, with transmission directions perpendicular to each other and each perpendicular to the edge of the machine platform 100; the conveying speed is adjustable and has intermittent or continuous conveying modes. After completing the loading and unloading tasks of the parts to be welded, the handling robot 300 is also responsible for transferring the welded FPC components from the welding platform 610 to the corresponding conveyor belt. Parts to be welded that are detected as having unqualified FPC wiring by the second vision component 626 before welding of the welding component 620 are transported to the defective product conveyor belt 710, while those that have been welded are transported to the finished product conveyor belt 720.
