Description

Technical Field

[0001] This utility model relates to the field of PCB board hole position inspection technology, specifically a PCB board hole position inspection machine. Background Technology

[0002] PCB boards are core components of electronic devices. The dimensional accuracy, positional deviation, and integrity of their holes directly affect the assembly accuracy of electronic components and the signal transmission performance of circuits. PCB hole inspection machines are key equipment in the PCB production process for automating the detection of hole parameters. By detecting indicators such as hole diameter, position coordinates, and hole wall quality, they enable rapid screening of defective products and are an important link in ensuring the quality of PCB production.

[0003] Existing PCB board hole position inspection machines suffer from problems when in use. Drilling debris, dust, and other impurities easily remain on the surface of the PCB board and in the inspection area. These impurities may cover the hole positions, leading to misjudgments by the hole position inspection equipment. Furthermore, during PCB board transportation, the board is prone to displacement due to inertia or vibration, causing the hole positions to misalign with the inspection baseline, thus affecting the accuracy of product quality judgment. Therefore, a PCB board hole position inspection machine is provided to improve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a PCB board hole position inspection machine. By setting up a dust suction component and an adjustment component, it solves the problem that existing PCB board hole position inspection machines are prone to leaving drilling debris, dust and other impurities on the PCB board surface and the inspection area. These impurities may cover the hole positions, leading to misjudgments by the hole position inspection equipment. In addition, the PCB board is prone to displacement due to inertia or vibration during transportation, causing the hole positions to be misaligned with the inspection baseline, thus affecting the accuracy of product quality judgment.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a PCB board hole inspection machine, comprising a workbench, a belt conveyor, hole inspection equipment, a dust collection component, and an adjustment component. The dust collection component is mounted on the belt conveyor and includes a U-shaped frame and a dust collection box. A fan is mounted on the U-shaped frame, and the air inlet of the fan is connected to a first dust collection pipe. A second dust collection pipe is connected to the first dust collection pipe, and multiple dust collection hoods are distributed on the second dust collection pipe. The air outlet of the fan is connected to a third dust collection pipe, which communicates with the dust collection box. The adjustment component is mounted on the belt conveyor and includes a threaded rod with two connecting plates threaded onto it. Baffles are mounted on the connecting plates.

[0007] Furthermore, the U-shaped frame is installed on the belt conveyor, and the U-shaped frame has an installation hole. The first dust suction pipe passes through the installation hole and is connected to the second dust suction pipe, which is installed on the U-shaped frame.

[0008] Furthermore, the adjustment assembly also includes a support plate, which is mounted on the belt conveyor. The support plate has a circular groove, one end of the threaded rod is rotatably engaged with the circular groove, and the other end of the threaded rod is connected to the drive source, which is mounted on the belt conveyor.

[0009] Furthermore, the adjusting assembly also includes a round rod and two support plates, both of which are mounted on the belt conveyor. The two ends of the round rod are respectively mounted on the two support plates, and the connecting plates have round holes that slide in conjunction with the round rod.

[0010] Furthermore, a belt conveyor is installed on the workbench, a hole position inspection device is installed on the belt conveyor, and an adjustment component is located between the hole position inspection device and the dust collection component.

[0011] Furthermore, the threaded rod is a bidirectional threaded rod, and the connecting plate has a U-shaped structure.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting up a dust collection component and using a fan to provide a negative pressure power source, sucks dust, metal shavings and other impurities from the PCB board surface into a dust collection box, and removes impurities from the PCB board surface in real time. This prevents dust from covering the PCB board surface or entering the holes, which could lead to misjudgments by the hole position inspection equipment. This solves the problem that existing PCB board hole position inspection machines are prone to drilling debris, dust and other impurities on the PCB board surface and inspection area, which may cover the holes and cause misjudgments by the hole position inspection equipment.

[0014] 2. This utility model, by setting an adjustment component, uses a bidirectional threaded rod to drive two connecting plates to move. The two connecting plates respectively drive two baffles to limit and correct the PCB board, ensuring that the PCB board moves along the center line of the belt during the conveying process. This solves the problem that existing PCB boards are prone to displacement due to inertia or vibration during conveying, resulting in misalignment between the hole position and the detection baseline, thus affecting the accuracy of product quality judgment.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a PCB board hole position inspection machine, including a workbench 1, a belt conveyor 2, a hole position inspection device 3, a dust collection component 4, and an adjustment component 5. The workbench 1 is used to support the core components such as the belt conveyor 2 and the hole position inspection device 3, ensuring the structural stability of the whole machine during operation.

[0022] The dust collection component 4 is mounted on the belt conveyor 2. The dust collection component 4 includes a U-shaped frame 401 and a dust collection box 407. A fan 402 is bolted to the U-shaped frame 401. The fan 402 provides a negative pressure power source, using high-speed airflow to suck up dust, metal shavings, and other impurities from the PCB board surface. It is the core power component for the dust collection function. A first suction pipe 403 is connected to the air inlet flange of the fan 402. A second suction pipe 404 is connected to the first suction pipe 403 via a quick-connect coupling. Multiple suction hoods 405 are distributed on the second suction pipe 404. The second suction pipe 404 and the multiple suction hoods 405 are connected via quick-connect couplings. The multiple suction hoods 405 expand the dust collection coverage area, ensuring that all impurities on the PCB board surface are effectively adsorbed. The outlet flange of the fan 402 is connected to a third suction pipe 406, which is connected to a dust collection box 407. The third suction pipe 406 directs the sucked-in impurities to the dust collection box 407. The dust collection box 407 is used to centrally store the adsorbed impurities. An air filter is installed inside the dust collection box 407, and a hole is opened at the bottom of the dust collection box 407. A door is hinged to one side of the dust collection box 407, which facilitates the periodic opening of the dust collection box 407 and cleaning of the internal dust. A sealing ring is usually installed between the dust collection box 407 and the door. The dust collection component 4 can remove impurities on the surface of the PCB board in real time, preventing dust from covering the surface of the PCB board or entering the holes, which may cause the hole inspection device 3 to make misjudgments (such as identifying impurities as hole blockages) or deviations in hole diameter and position measurement.

[0023] The adjustment component 5 is installed on the belt conveyor 2. The adjustment component 5 includes a threaded rod 501, which is a bidirectional threaded rod with left and right helical threads. When rotated, it can drive two connecting plates 502 to move synchronously in opposite or opposite directions, thereby adjusting the distance between the baffles 503 to accommodate PCBs of different widths. The threaded rod 501 is threaded with two connecting plates 502, which have a U-shaped structure. The baffles 503 are bolted to the connecting plates 502. The baffles 503 can laterally limit the PCBs during transport, preventing them from shifting or shaking on the belt conveyor 2 due to inertia. This ensures that the center of the PCB is aligned with the detection baseline of the hole inspection device 3, reducing the risk of detection misalignment.

[0024] The U-shaped frame 401 is bolted to the belt conveyor 2. The U-shaped frame 401 has a mounting hole 408. The first dust suction pipe 403 passes through the mounting hole 408 and is connected to the second dust suction pipe 404. The second dust suction pipe 404 is installed on the U-shaped frame 401 by a buckle.

[0025] The adjustment assembly 5 also includes a support plate 504, which is bolted to the belt conveyor 2. A circular groove 505 is provided on the support plate 504. One end of the threaded rod 501 is rotatably engaged with the circular groove 505 through a bearing. The other end of the threaded rod 501 is connected to the power output shaft of the drive source through a coupling. The drive source is bolted to the frame of the belt conveyor 2. The drive source can be a servo motor.

[0026] The adjusting assembly 5 also includes a round rod 506 and two support plates 507. Both support plates 507 are bolted to the belt conveyor 2. The two ends of the round rod 506 are respectively welded to the two support plates 507. A round hole 508 is provided on the connecting plate 502. The round hole 508 is slidably engaged with the round rod 506. The sliding engagement between the round rod 506 and the round hole 508 can limit the connecting plate 502 to move only along the axial direction of the round rod 506, ensuring that the two connecting plates 502 always remain parallel and preventing deviation or tilting during adjustment.

[0027] The belt conveyor 2 is bolted to the workbench 1, and the hole position inspection device 3 is bolted to the frame of the belt conveyor 2. The belt conveyor 2 consists of a conveyor belt, a drive unit, rollers, and a frame, etc., to achieve stable and uniform conveying of the PCB board. The hole position inspection device 3 consists of components such as an optical detection module, an image acquisition unit, a photoelectric sensor, and a bracket, etc., to accurately detect key parameters such as the size, position deviation, and hole diameter accuracy of the holes on the PCB board, to identify defects in a timely manner, and to ensure that the product meets quality standards (both the belt conveyor 2 and the hole position inspection device 3 are existing technologies and will not be described in detail here).

[0028] The adjustment component 5 is located between the hole position inspection device 3 and the dust collection component 4. During operation, the dust collection component 4 can first absorb impurities on the surface of the PCB board, and then the adjustment component 5 can adjust the position of the PCB board so that the center of the PCB board is aligned with the detection baseline of the hole position inspection device 3, which facilitates the subsequent inspection of the PCB board by the hole position inspection device 3.

[0029] During operation, the PCB board to be inspected is first placed at the input end of the belt conveyor 2 and the belt conveyor 2 is started. The belt on the belt conveyor 2 drives the PCB board towards the dust collection component 4 and the hole inspection device 3. When the PCB board enters the area of ​​the dust collection component 4, the fan 402 is started, and the fan 402 generates negative pressure. The dust collection hood 405 on the second dust collection pipe 404 is close to the surface of the PCB board, sucking in dust, drilling debris and other impurities from the inspection area. These are then transported to the dust collection box 407 for centralized storage through the first dust collection pipe 403 and the third dust collection pipe 406. When the PCB board enters the area of ​​the adjustment component 5, the servo motor is started to drive the threaded rod according to the width of the PCB board to be inspected. Rotating 501 causes the threaded rod 501 to drive the two connecting plates 502 to slide along the round rod 506. The two connecting plates 502 drive the side baffles 503 to limit and correct the PCB board, ensuring that the PCB board moves along the center line of the belt during the conveying process. After correction, the servo motor reverses and drives the side baffles 503 to return to their original positions, which facilitates the limiting of the next PCB board. When the PCB board completely enters the detection area of ​​the hole position inspection device 3, the device starts the detection program to automatically detect parameters such as the position coordinates of the hole, the hole diameter, and the smoothness of the hole wall, and provides real-time feedback of the results. After the detection is completed, the PCB board continues to be conveyed to the output end by the belt conveyor 2, completing the hole position inspection of the PCB board.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
