[0042] like Figure 1-3 As shown, the present application provides an integrated PCB board inspection machine, including a detection machine body 1, a bracket 2 and a camera are respectively installed at the inner end of the detection machine body 1, the camera is located on the upper side of the bracket 2, a driving assembly 3 is arranged on the lower side of the bracket 2, and a pair of mutually symmetrical movable blocks 4 are slidably connected to the upper side of the bracket 2, the bottom ends of the movable blocks 4 pass through the bracket 2 and extend to the lower side of the bracket 2, a pair of movable blocks 4 are arranged on one side close to each other with a vertical clamping plate 6, a pair of limit columns 5 are fixedly connected between the movable blocks 4 and the vertical clamping plate 6, a plurality of slide grooves 10 are opened on the upper end of the bracket 2, and the bracket 2 A pair of symmetrical transverse positioning rods 11 are arranged on the upper side, and the transverse positioning rods 11 are slidably connected to the slide groove 10. A pair of transverse positioning rods 11 are slidably connected to a transverse clamping plate 13 at one end close to each other. The driving component 3 includes a servo motor 301, and the servo motor 301 is installed at the bottom end of the bracket 2, and the output end of the servo motor 301 is fixedly connected to a bidirectional screw rod 302, and the bidirectional screw rod 302 is rotatably connected to the bracket 2. The driving component 3 also includes a pair of screw sleeves 303, and the screw sleeves 303 are fixedly connected to the bottom end of the movable block 4, and the screw sleeves 303 match the bidirectional screw rod 302.

[0043] An all-in-one PCB inspection machine is a device used to inspect the quality and performance of printed circuit boards. It usually consists of multiple functional modules integrated into one machine to provide comprehensive PCB inspection and analysis functions. The most important of these is the visual inspection module, which uses a high-resolution camera to perform visual inspection of PCB boards to detect component positions, pin connections, welding quality, short circuits, open circuits and other issues.

[0044] When inspecting the PCB board, it is necessary to position the PCB board so that the PCB board is located at the center of the bracket 2. The positioning can provide a stable position and alignment to ensure that the PCB board will not move or offset during the inspection process. At the same time, it is convenient for the camera to determine the position and direction of the PCB board for accurate visual inspection. In this solution, the user can place the PCB board to be inspected between a pair of vertical clamping plates 6 and a pair of horizontal clamping plates 13, so that the long side of the PCB board is close to the horizontal clamping plate 13, and the wide side is close to the vertical clamping plate 6. Then start the servo motor 301 to drive the bidirectional screw rod 302 to rotate, and the bidirectional screw rod 302 drives a pair of screw sleeves 303 to move synchronously in the direction of approaching each other, thereby driving a pair of movable blocks 4 to move, and the movable blocks 4 drive a pair of vertical clamping plates 6 to approach each other, and at the same time drive the vertical positioning rod 7 to move.

[0045] A vertical positioning rod 7 is arranged between the movable block 4 and the vertical clamping plate 6, the limiting column 5 passes through the vertical positioning rod 7, and the outer end of the limiting column 5 is sleeved with a first spring, and the two ends of the first spring are respectively fixedly connected to the movable block 4 and the vertical positioning rod 7, a pair of mutually symmetrical rectangular holes 8 are opened on the movable block 4, both ends of the transverse positioning rod 11 pass through the rectangular hole 8, and a pair of mutually symmetrical extrusion blocks 12 are fixedly connected to the outer end of the transverse positioning rod 11, and the inner wall of the rectangular hole 8 is rotatably connected with a roller 9, and the roller 9 abuts against the extrusion block 12.

[0046] When the vertical positioning rod 7 moves, the roller 9 at the inner end of the rectangular hole 8 will squeeze the inclined edge of the squeezing block 12, and then push the pair of lateral positioning rods 11 to move in the rectangular hole 8 and approach each other while the vertical positioning rod 7 moves. In this scheme, the spacing between the pair of vertical clamping plates 6 and the spacing between the pair of lateral clamping plates 13 are set differently, so that the pair of lateral clamping plates 13 will first abut against the long side of the PCB board and push the PCB board to the center position of the upper end of the bracket 2 until the pair of lateral clamping plates 13 abut against the PCB board. At this time, the lateral positioning rod 11 will be subject to the resistance of the PCB board and stop moving, thereby forcing the vertical positioning rod 7 to stop moving, but the movable block 4 will continue to push the limit column 5 to slide on the vertical positioning rod 7 and squeeze the first spring, thereby forcing the pair of vertical clamping plates 6 to continue to approach When one of the vertical clamping plates 6 first abuts against a pair of PCB boards, it will push the PCB board to move toward the center position of the bracket 2, and then the PCB board drives the horizontal clamping plate 13 to move. The purpose of such a setting is: in this scheme, the spacing between the pair of horizontal clamping plates 13 and the pair of vertical clamping plates 6 can be flexibly adjusted, so as to adapt to PCB boards of different sizes. However, most PCB boards have long sides and wide sides, and the horizontal clamping plates 13 will first abut against the long sides. At this time, in order to avoid the long sides of the PCB board being damaged by friction with the surface of the horizontal clamping plates 13 when the subsequent vertical clamping plates 6 push the PCB board to move, the horizontal clamping plates 13 are set to be slidably connected with the horizontal positioning rods 11, so that the PCB board can drive the horizontal clamping plates 13 to slide, thereby avoiding friction.

[0047] like Figure 4-5 As shown, a pair of transverse positioning rods 11 are provided with a base 14 on one side away from each other, the base 14 is fixedly connected to the bracket 2, and a plurality of second springs are fixedly connected between the base 14 and the transverse positioning rod 11, a magnet 15 is installed at one end of the base 14 close to the transverse positioning rod 11, and a metal block 16 matching the magnet 15 is installed at the center position of the transverse clamping plate 13 close to one end of the transverse positioning rod 11.

[0048] When a pair of transverse positioning rods 11 approach each other, multiple second springs will be pulled, so that when the detection is completed, the pair of vertical positioning rods 7 will be controlled to move away from each other through the driving component 3. At this time, the pair of transverse positioning rods 11 will be reset under the action of the second springs and abut against the base 14. At this time, the magnet 15 at one end of the base 14 will generate magnetic attraction with the metal block 16 at the inner end of the transverse clamping plate 13, and then the transverse clamping plate 13 will be driven to slide through the metal block 16, so that the transverse clamping plate 13 returns to the center position of one end of the transverse positioning rod 11, which is convenient for subsequent use.

[0049] Working principle:

[0050] When in use, the user places the PCB board to be tested between a pair of vertical clamping plates 6 and a pair of horizontal clamping plates 13, so that the long side of the PCB board is close to the horizontal clamping plate 13, and the wide side is close to the vertical clamping plate 6, then starts the servo motor 301 to drive the bidirectional screw rod 302 to rotate, and the bidirectional screw rod 302 drives a pair of screw sleeves 303 to move synchronously in the direction of approaching each other, thereby driving a pair of movable blocks 4 to move, and through the movable blocks 4, drives a pair of vertical clamping plates 6 to approach each other, and at the same time drives the vertical positioning rod 7 to move, when the vertical positioning rod 7 moves, the roller 9 at the inner end of the rectangular hole 8 will squeeze the inclined edge of the squeezing block 12, and then while the vertical positioning rod 7 moves, push the pair of horizontal positioning rods 11 to move in the rectangular hole 8 and approach each other, the pair of horizontal clamping plates 13 will first abut against the long side of the PCB board, and push the PCB board to the center position of the upper end of the bracket 2, until the pair of horizontal clamping plates 13 are both abutted against the PCB board, at this time the horizontal positioning rod 11 will be stopped by the resistance of the PCB board. When the first spring 14 is pressed against the first PCB board, the first spring 14 will be pressed against the second PCB board, and the second spring 14 will be pressed against the second PCB board, so that the first PCB board will be pressed against the second PCB board, and the second PCB board will be pressed against the second PCB board, so that the second PCB board will be pressed against the second PCB board, and the second PCB board will be pressed against the second PCB board, so that the second PCB board will be pressed against the second PCB board, and the second PCB board will be pressed against the second PCB board, so that the second PCB board will be pressed against the second PCB board, and the second PCB board will be pressed against the second PCB board, so that the second PCB board will be pressed against the second PCB board, and the second PCB board will be pressed against the second PCB board, so that the second PCB board will be pressed against the second PCB board, and the second PCB board will be pressed against the second PCB board, so that the second PCB board will be pressed against the second PCB board,
