As the carrier of internal components of user terminals, circuit boards are the core components of user terminal devices. In order to ensure the quality of the final produced user terminals, it is often necessary to inspect the soldering quality of the components on the circuit boards when they leave the factory.

[0003] In the current technology, flexible circuit boards (PCBs) are usually inspected manually by visual inspection. This method is labor-intensive and can easily cause visual fatigue, dizziness, and eye strain, leading to missed or incorrect inspections. In addition, when using automatic visual inspection methods to inspect PCBs, dust or impurities on the PCBs can also affect the inspection accuracy, thus failing to meet production requirements. Therefore, a welding inspection device with rapid positioning capability is proposed to solve the problems mentioned above. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4This embodiment of a welding inspection device with rapid positioning includes a conveying device 1, on which several equidistantly distributed platforms 2 are mounted. A shielding frame 3 is mounted above the conveying device 1, and photoelectric sensors can be installed on the shielding frame 3 to accurately move the platforms 2 under the shielding frame 3, achieving rapid positioning. A detection device 4 is installed on the shielding frame 3; wherein, the detection device 4 includes an electric telescopic rod 41 fixed to the upper surface of the shielding frame 3, and a mounting frame 42 is provided on the inner side of the shielding frame 3. Two detection probes 43 are mounted on the mounting frame 42, enabling simultaneous detection by the dual probes, shortening the single-piece inspection time, and adapting to the high-speed operation requirements of the assembly line. A guide sleeve 45 is fixed inside the shielding frame 3. A lifting shaft 44, penetrating the interior of the guide sleeve 45, is fixed on the upper surface of the mounting frame 42. The lifting shaft 44 is connected to the output end of the electric telescopic rod 41. Specifically, the guide sleeve 45 is a hollow shaft, and a guide shaft 46 is fixed inside the guide sleeve 45. A guide wheel 47 is rotatably mounted on one end of the guide shaft 46. Both the conveying device 1 and the testing device 4 are conventional technologies known to the public in the prior art. Therefore, their specific structural composition and working principle will not be described in detail in this article.

[0025] It should be noted that the lifting shaft 44 has a guide groove 48 inside, which surrounds the outer surface of the lifting shaft 44. The guide groove 48 consists of a straight groove and a spiral groove, and the guide wheel 47 is in rolling connection with the guide groove 48. When the electric telescopic rod 41 drives the lifting shaft 44 to rise and fall, the spiral groove forces the lifting shaft 44 to rotate simultaneously. During the vertical lifting process, the detection probe 43 automatically adjusts the horizontal angle to achieve multi-angle and all-round detection of the welded parts, avoiding missed detections caused by fixed angles and improving detection accuracy. A connecting plate 49 is fixed to the output end of the electric telescopic rod 41, and a rotating joint fixed to the lower surface of the connecting plate 49 is rotatably installed on the top of the lifting shaft 44. The rotating joint is connected to the connecting piece.

[0026] To further improve the detection effect, the shielding frame 3 is also equipped with a cleaning structure 5 that works in conjunction with the detection equipment 4. The cleaning structure 5 includes a guide plate 51 that slides through the interior of the shielding frame 3. A cleaning brush 52 is provided on one side of the guide plate 51, and a connecting piece is provided between the other side of the guide plate 51 and the lifting shaft 44. A collection piece is provided on the outer wall of the shielding frame 3 to reciprocate with the guide plate 51. It should be noted that the cleaning brush 52 is located on one side of one of the platforms 2. The guide plate 51 is T-shaped, and an adjusting rod 53 connected to the upper surface of the cleaning brush 52 is installed on the internal thread of the horizontal part of the guide plate 51. The distance between the cleaning brush 52 and the platform 2 can be adjusted by rotating the adjusting rod 53. Alternatively, the adjusting rod 53 can also be adjusted by a spring clip. Specifically, the connecting arm 55 hinges the guide plate 51 to the rotating joint of the lifting shaft 44. When the lifting shaft 44 of the testing device 4 is reset after completing the test, the upward movement of the lifting shaft 44 pulls the guide plate 51 to slide back and forth in the shielding frame 3 through the connecting arm 55, driving the cleaning brush 52 to automatically clean the surface of the shelf 2 or the welded parts.

[0027] The connector includes a connecting seat 54 fixed to the side of the guide plate 51 away from the cleaning brush 52, and a connecting arm 55 hinged between the top side of the connecting seat 54 and the rotary joint. A suction tube 511 for use with the collecting component is installed inside the mounting bracket 42. The collecting component includes a stopper cylinder 56 fixed to the outer wall of the shielding frame 3. A piston 57 is slidably disposed inside the stopper cylinder 56. A connecting rod 58 extending to the outside of the stopper cylinder 56 is fixed to one side of the piston 57, and the end of the connecting rod 58 is fixed to the outer wall of the connecting seat 54. Check valves 59 are installed on both the outer wall of the stopper cylinder 56 and the piston 57, and an air extraction pipe 510 is installed between the check valve 59 on the stopper cylinder 56 and the suction tube 511. A detachable mesh 512 is installed inside the stopper cylinder 56. When the guide plate 51 reciprocates, the connecting seat 54 drives the piston 57 to slide inside the stopper cylinder 56 via the connecting rod 58. When piston 57 moves backward, a negative pressure is generated inside plug cylinder 56, opening check valve 59. Impurities are drawn into plug cylinder 56 through suction pipe 511 and suction pipe 510, while gas is discharged through another check valve 59. Impurities are filtered by screen 512 and remain inside plug cylinder 56. A discharge hole is provided inside plug cylinder 56, and a plug can be installed in the discharge hole. The depth of plug cylinder 56 is adapted to the moving height of detection probe 43. A buffer spring is installed between the outer wall of plug cylinder 56 and the outer surface of connecting rod 58.

[0028] The working principle of the above embodiments is as follows:

[0029] The conveying equipment 1 operates continuously or in a step-by-step manner. The equidistant platform 2 on it carries the welding workpiece and moves it. The workpiece is conveyed to the inspection station below the shielding frame 3. When the workpiece reaches the inspection position, the electric telescopic rod 41 is activated, pushing the connecting plate 49 to move downward. The connecting plate 49 pushes the lifting shaft 44 downward. The lifting shaft 44 moves in a straight line downward along the guide shaft 46 inside the guide sleeve 45. The guide wheel 47 rolls in the straight groove part of the guide groove 48 inside the lifting shaft 44. At this time, the lifting shaft 44 does not rotate. The lifting shaft 44 drives the mounting frame 42 at its bottom and the two inspection probes 43 to descend vertically together and approach the weld. When the guide wheel 47 enters the spiral groove part of the guide groove 48, the guide wheel 47 forces the lifting shaft 44 to rotate around its own axis. The rotation of the lifting shaft 44 drives the two inspection probes 43 to rotate around the axis of the lifting shaft 44 through the mounting frame 42 at its bottom. At this time, the inspection probes 43 perform rotation scanning while contacting or approaching the weld surface to achieve comprehensive inspection of the weld.

[0030] When the lifting shaft 44 moves upward, it drives the connecting arm 55 to move downward through the rotating joint at the top. The connecting arm 55 pulls the connecting seat 54, which in turn pulls the guide plate 51 to slide laterally within the shielding frame 3. The cleaning brush 52 fixed on one side of the guide plate 51 moves accordingly and brushes over the weld seam of the workpiece on the shelf 2.

[0031] When the lifting shaft 44 moves down and the guide plate 51 moves laterally to pull the connecting seat 54, it also pulls the connecting rod 58 fixed to the connecting seat 54. The connecting rod 58 pulls the piston 57 inside the plug cylinder 56 to move outward. The piston 57 moves and generates negative pressure inside the plug cylinder 56. The negative pressure sucks up the debris swept down by the cleaning brush 52 through the suction pipe 510 and the suction pipe 511.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
