[0002] During the circuit board production process, soldering is required. After soldering is complete, the solder joints need to be inspected for quality. After soldering, the solder joints exhibit a conical shape. Currently, AOI (Automated Optical Inspection) technology is commonly used. This technology uses optical principles to detect common defects encountered during soldering. AOI is a new and rapidly developing testing technology, with many manufacturers introducing AOI testing equipment. During automatic inspection, the machine uses a camera to scan the circuit board, capture images, and compare the tested solder joints with qualified parameters in a database. After image processing, defects on the circuit board are detected and marked on a display or through automatic identification for maintenance personnel to repair.

[0015] Beneficial effects of the present invention:

[0016] (1) The robot device for high-efficiency welding quality inspection described in the present invention is provided with a lifting mechanism. The rotation of the motor drives the rotation of the threaded rod, and then drives the working box to move downward along the side wall of the support rod. At this time, the guide rod is gradually reset under the spring force of the second spring, so that the limit plate, the movable ring and the guide rod move upward. The limit plate slides along the side wall of the fixed plate and is stuck between the two rubber protrusions. At this time, the fixed pin is between the limit blocks. When the lowest detection wheel contacts the side wall of the welding point, the first sliding rod moves to the left. At this time, the first spring contracts. Due to the setting of the support plate, the movement of the first sliding rod drives the movable plate When the detection wheel detects a concave defect, the first sliding rod drives the first slider to move to the left. At this time, the fixed pin is against the side wall of the limit block, so that the movable plate cannot move to the right. At this time, the first liquid outlet is aligned with the liquid inlet pipe, and the marking liquid in the liquid storage tank enters the liquid inlet pipe through the liquid supply pipe, enters the connecting pipe and is discharged through the liquid outlet pipe, thereby marking the defective solder joints, making the solder joint defect detection more convenient and more reliable, and through the movement of the mounting cover, rapid detection of multiple solder joints is achieved, and the detection efficiency is higher.

[0017] (2) The robot device for efficient welding quality inspection described in the present invention is provided with a plurality of inspection wheels. When the first inspection wheel contacts the side wall of the welding spot, it drives the movable plate to move to the left. At this time, due to the setting of the moving rod, the moving block does not contact the side wall of the limit rod. At this time, the moving block always abuts against the side wall of the through hole, ensuring the sealing of the through hole and preventing the marking liquid from accidentally leaking out when the moving plate moves to the left, thereby affecting the accuracy of the inspection result. In addition, by providing a protective mechanism, when the second inspection wheel contacts the side wall of the welding spot, the moving rod is under the action of the spring force of the sixth spring. When the second spring is pressed against the stopper, the second slider moves to the right, causing the third sliding surface to slide on the side wall of the limit rod, thereby causing the moving block to slide to the left along the side wall of the fixed rod. At the same time, the fifth spring contracts, and the through hole opens. The marking liquid enters the liquid inlet pipe through the liquid supply pipe, enters the connecting pipe through the second liquid outlet hole, and is discharged through the liquid outlet pipe, thereby achieving multiple markings of the defective solder joints, making the marking effect better and easier to identify.

[0018] (3) The robot device for high-efficiency welding quality inspection described in the present invention is provided with an adjustment mechanism. When there is a position deviation between the working tube and the welding point during inspection, the working tube and the welding point can be adaptively aligned and adjusted by rotating the third sleeve and moving the third rod, so that the inspection result is more accurate.

[0035] like Figure 5 、 6 As shown, the detection mechanism 6 includes a plurality of sliding rod groups arranged in an array and inserted on the side wall of the working tube 11, the sliding rod group includes a first sliding rod 603 and a plurality of second sliding rods 610 arranged in an array, one end of the sliding rod group is fixedly connected to a U-shaped plate 602, and the side wall of the U-shaped plate 602 is rotatably connected to a detection wheel 601, and the other end of the sliding rod group passes through the side wall of the working tube 11 and is fixedly connected to a slider group, the slider group includes a first slider 608 and a plurality of second sliders 609 arranged in an array, and the side wall of the working box 10 is fixedly connected to the first The first sleeve 604 has a first sleeve rod 611 inserted into the side wall of the first sleeve 604.

The two ends of the first spring 605 respectively abut against the side walls of the working box 10 and the slider group. The side wall of the first sliding rod 603 is fixedly sleeved with a connecting plate 606. One side wall of the connecting plate 606 abuts against the side wall of the working tube 11. The other side wall of the connecting plate 606 is fixedly connected to two symmetrically arranged support plates 607.

[0036] During operation, when the bottom detection wheel 601 contacts the side wall of the welding point 101, the first sliding rod 603 moves to the left, and the first spring 605 contracts. Due to the setting of the support plate 607, the movement of the first sliding rod 603 drives the synchronous movement of the moving plate 702, and the fixed pin 308 slides along the side wall of the first sliding surface 311. At this time, the seventh spring 1305 contracts. When the detection wheel 601 detects a concave defect, the first sliding rod 603 drives the first slider 608 to move to the left. At this time, the fixed pin 308 and the first slider 608 are in contact. The side walls of the limit block 310 are against each other, so that the movable plate 702 cannot move to the right. At this time, the first liquid outlet 703 is aligned with the liquid inlet pipe 709, and the marking liquid in the liquid storage tank 701 enters the liquid inlet pipe 709 through the liquid supply pipe 707, and enters the connecting pipe 706 and is discharged through the liquid outlet pipe 708, thereby marking the defective welds 101, making the defect detection of the welds 101 more convenient and more reliable, and by moving the mounting cover 2, rapid detection of multiple welds 101 is achieved, and the detection efficiency is higher.

[0037] like Figure 4 、 6 The marking mechanism 7 includes a movable plate 702 sleeved on the side wall of the slider group, and a mounting hole 704 is provided on the side wall of the movable plate 702 and the slider group box.

[0038] When the first inspection wheel 601 contacts the side wall of the solder joint 101, it drives the movable plate 702 to move to the left. At this time, due to the setting of the movable rod 901, the movable block 809 does not contact the side wall of the limit rod 812. At this time, the movable block 809 always contacts the side wall of the through hole 805 to ensure the sealing of the through hole 805, thereby preventing the marking liquid from accidentally leaking out when the movable plate 702 moves to the left, affecting The detection result is accurate, and by setting the protection mechanism 8, when the second detection wheel 601 contacts the side wall of the welding point 101, the moving rod 901 is gradually reset under the spring force of the sixth spring 903, so that the moving rod 901 and the slide groove 905 no longer conflict with each other. At this time, the partition 802 is reset under the action of the fourth spring 804, thereby extending the moving block 809. When a concave defect is detected, the second slider 609 moves to the right, so that the third sliding surface 811 slides on the side wall of the limiting rod 812, thereby making the moving block 809 slide to the left along the side wall of the fixed rod 808. At the same time, the fifth spring 807 contracts, and the through hole 805 is opened. The marking liquid enters the liquid inlet pipe 709 through the liquid supply pipe 707, and enters the connecting pipe 706 through the second liquid outlet hole 705 and is discharged through the liquid outlet pipe 708, thereby achieving multiple markings of the welding point 101 at the defect, making the marking effect better and easier to identify.

[0040] When working, by setting the lifting mechanism 4, the rotation of the motor 401 drives the rotation of the threaded rod 402, and then drives the working box 10 to move downward along the side wall of the support rod 405. At this time, the guide rod 309 is gradually reset under the spring force of the second spring 302, so that the limit plate 304, the movable ring 305 and the guide rod 309 move upward, and the limit plate 304 slides along the side wall of the fixed plate 306 and is stuck between the two rubber protrusions 307. At this time, the fixing pin 308 is between the limit blocks 310, and when the detection wheel 601 moves downward and all detections are completed, the guide rod 309 is against the side wall of the circuit board 1, so that the movable ring 305 passes over the rubber protrusion 307 and moves upward along the side wall of the fixed plate 306, so that the fixing pin 308 is staggered with the limit block 310. At this time, the movable plate 702 is reset under the spring force of the first spring 605, ensuring that the marking liquid will not leak when the detection wheel 601 moves upward and resets, thereby ensuring the accuracy of the detection result.

At this time, the moving block 809 always abuts against the side wall of the through hole 805, ensuring the sealing of the through hole 805, and preventing the marking liquid from accidentally leaking out when the moving plate 702 moves to the left, thereby affecting the accuracy of the detection result. In addition, by providing the protective mechanism 8, when the second detection wheel 601 contacts the side wall of the welding point 101, the moving rod 901 is gradually reset under the spring force of the sixth spring 903, so that the moving rod 901 and the slide groove 905 are no longer abutted. At this time, the partition 802 is reset under the action of the fourth spring 804. As a result, the movable block 809 is extended. When a concave defect is detected, the second slider 609 moves to the right, causing the third sliding surface 811 to slide on the side wall of the limit rod 812, thereby causing the movable block 809 to slide to the left along the side wall of the fixed rod 808. At the same time, the fifth spring 807 contracts, and the through hole 805 is opened. At this time, the marking liquid enters the liquid inlet pipe 709 through the liquid supply pipe 707, and enters the connecting pipe 706 through the second liquid outlet hole 705 and is discharged through the liquid outlet pipe 708, thereby achieving multiple marking of the weld point 101 at the defective location, making the marking effect better and easier to identify.

[0044] Specifically, the limiting mechanism 9 includes a slide groove 905 provided on the side wall of the moving block 809, the slide groove 905 includes a fourth sliding surface 906 arranged at an angle, the side wall of the working hole 801 is fixedly connected to a bracket 904, and a moving rod 901 is inserted into the side wall of the bracket 904. One end of the moving rod 901 abuts against the side wall of the fourth sliding surface 906, and the other end of the moving rod 901 passes through the side wall of the second slider 609 and abuts against the side wall of the working tube 11. The side wall fixing sleeve of the moving rod 901 is provided with a fixing ring 902, and the side wall sleeve of the moving rod 901 A sixth spring 903 is provided, and the two ends of the sixth spring 903 are respectively against the side walls of the bracket 904 and the fixing ring 902. When the first detection wheel 601 contacts the side wall of the welding point 101, it drives the movable plate 702 to move to the left. At this time, due to the setting of the movable rod 901, the movable block 809 does not contact the side wall of the limit rod 812. At this time, the movable block 809 is always against the side wall of the through hole 805 to ensure the sealing of the through hole 805, thereby avoiding accidental leakage of the marking liquid when the movable plate 702 moves to the left, thereby affecting the accuracy of the detection result.

[0045] Specifically, the telescopic mechanism 13 includes an installation cavity 1306 opened on the side wall of the limit plate 304, the side wall of the installation cavity 1306 is provided with a strip opening 1301, the limit block 310 is inserted in the strip opening 1301, the side wall of the installation cavity 1306 is slidably connected with a reinforcing plate 1302, the reinforcing plate 1302 is fixed to the side wall of the limit block 310, the side wall of the installation cavity 1306 is fixedly connected with a fourth sleeve 1304, the side wall of the fourth sleeve 1304 is inserted with a fourth rod 1303, the other end of the fourth rod 1303 is fixed to the side wall of the reinforcing plate 1302, the side wall of the fourth sleeve 1304 is sleeved with a seventh spring 1305, the two ends of the seventh spring 1305 are respectively fixed to the reinforcing plate 1302 and the side wall of the installation cavity 1306, which guides and limits the movement of the limit block 310.

[0046] Specifically, the inclination angle of the fourth sliding surface 906 is 20° smaller than the inclination angle of the third sliding surface 811, ensuring that when the moving rod 901 abuts against the fourth sliding surface 906, the component force along the horizontal direction is small, and the moving block 809 cannot move to the left, and when the third sliding surface 811 abuts against the side wall of the limiting rod 812, the horizontal component force is larger, thereby opening the through hole 805.

[0047] Working principle: During operation, first, the mounting cover 2 is moved so that the notch 202 passes through the welding point 101, and the working tube 11 is aligned with the welding point 101. By setting the adjustment mechanism 5, during detection, when there is a position deviation between the working tube 11 and the welding point 101, the third sleeve 503 can be rotated and the third sleeve rod 502 can be moved to achieve adaptive alignment adjustment of the working tube 11 and the welding point 101, so that the detection result is more accurate. Then the rotation of the motor 401 is started to drive the rotation of the threaded rod 402, and then drive the working box 10 to move downward along the side wall of the support rod 405. At this time, the guide rod 309 is gradually reset under the spring force of the second spring 302, so that the limit plate 304, the movable ring 305 and the guide rod 309 move upward, and the limit plate 304 slides along the side wall of the fixed plate 306 and is stuck between the two rubber protrusions 307. At this time, the fixing pin 308 is between the limit block 310 When the inspection wheel 601 detects a concave defect, the first sliding rod 603 drives the first slider 608 to move to the left. At this time, the fixed pin 308 abuts against the side wall of the limit block 310, making the movable plate 702 unable to move to the right. At this time, the first liquid outlet 703 is aligned with the liquid inlet pipe 709, and the marking liquid in the liquid storage tank 701 enters the liquid inlet pipe 709 through the liquid supply pipe 707, enters the connecting pipe 706, and is discharged through the liquid outlet pipe 708, thereby marking the defective solder joint 101, making it more convenient to detect defects in the solder joint 101.

[0048] By setting multiple detection wheels 601, when the first detection wheel 601 contacts the side wall of the welding point 101, it drives the moving plate 702 to move to the left. At this time, due to the setting of the moving rod 901, the moving block 809 does not contact the side wall of the limiting rod 812. At this time, the moving block 809 always abuts against the side wall of the through hole 805, ensuring the sealing of the through hole 805, avoiding the accidental leakage of the marking liquid when the moving plate 702 moves to the left, affecting the accuracy of the detection result, and by setting the protective mechanism 8, when the second detection wheel 601 contacts the side wall of the welding point 101, the moving rod 901 is gradually reset under the spring force of the sixth spring 903, so that the moving rod 901 and the sliding plate 702 are not in contact. The grooves 905 no longer abut against each other. At this time, the partition 802 is reset under the action of the fourth spring 804, thereby extending the movable block 809. When a concave defect is detected, the second slider 609 moves to the right, causing the third sliding surface 811 to slide on the side wall of the limiting rod 812, thereby causing the movable block 809 to slide to the left along the side wall of the fixed rod 808. At the same time, the fifth spring 807 contracts, and the through hole 805 is opened. The marking liquid enters the liquid inlet pipe 709 through the liquid supply pipe 707, enters the connecting pipe 706 through the second liquid outlet hole 705, and is discharged through the liquid outlet pipe 708. This achieves multiple marking of the defective solder joint 101, making the marking effect better and easier to identify.

[0049] When the detection wheel 601 moves downward and all detection is completed, the guide rod 309 abuts against the side wall of the circuit board 1, so that the movable ring 305 passes over the rubber protrusion 307 and moves upward along the side wall of the fixed plate 306, so that the fixed pin 308 is staggered with the limit block 310. At this time, the movable plate 702 is reset under the spring force of the first spring 605, ensuring that the marking liquid will not leak out when the detection wheel 601 moves upward to reset, thereby ensuring the accuracy of the detection result.
