Description

Technical Field

[0001] The utility model relates to the technical field of dotting mechanisms, in particular to a dotting pen device with double dotting functions. Background Art

[0002] In the SMT industry, defective products are usually produced during the production process of PCBs. The traditional way to mark defective products is to use a dotting mechanism to mark the defective products, thereby distinguishing good products from defective products.

[0003] Currently, a Chinese utility model with the announcement number CN215620906U discloses a dotting device for pallet-type products, comprising: a frame and a pallet carrier and a dotting mechanism arranged on the frame; the dotting mechanism comprises a robot and a dotting marker; the output end of the robot is connected to a horizontally arranged first connecting plate through an adapter; the first connecting plate is connected to a first mounting seat for mounting the dotting marker; the dotting marker is fixed to the first mounting seat through a fixing block.

[0004] There are many types of defective products produced in PCB production. For example, some defective products need to be re-tested, while others need to be directly scrapped. Therefore, in the automated production of PCBs, different types of defective products need to be marked and distinguished to facilitate subsequent production.

[0005] However, the existing dotting mechanism can only mark one type of defective product, and its function is relatively single, which cannot meet the requirement of marking different types of defective products. Utility Model Content

[0006] The purpose of the utility model is to provide a dotting pen device with a double dotting function, which has the advantage of marking and distinguishing different types of defective products and classifying the defective products.

[0007] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions:

[0008] A dotting pen device with dual dotting functions, comprising a rotating frame and at least two dotting mechanisms arranged on the rotating frame and having different marking colors;

[0009] The dotting mechanism includes a driving member fixed on a rotating frame, a connecting frame fixedly connected to an action end of the driving member, a dotting pen slidably arranged on the connecting frame, and a buffer assembly arranged between the connecting frame and the dotting pen.

[0010] Through the above technical solution, dotting mechanisms with different marking colors are used to mark different types of defective products; the driving part is used to drive the connecting frame to drive the dotting pen to slide vertically, and the dotting pen is used to mark defective products; due to the different heights of the PCB boards, the buffer component plays a buffering role during the marking process of the dotting pen.

[0011] In one embodiment of the present invention, the rotating frame is provided with two dotting mechanisms with different marking colors.

[0012] Through the above technical solution, two dotting mechanisms with different marking colors are used to mark defective products that need to be re-inspected and defective products that are directly scrapped, thereby distinguishing different types of defective products, providing strong support for quality traceability and process optimization, and helping to continuously improve the inspection process to meet diverse production needs.

[0013] In one embodiment of the present invention, a guide sleeve is fixedly provided on the dotting pen, a guide hole is provided on the connecting frame, and the guide sleeve is slidably assembled in the guide hole;

[0014] A limit block is fixedly arranged on the guide sleeve below the connecting frame.

[0015] Through the above technical solution, the guide sleeve slides in the guide hole, and the limit block is used to limit the dotting pen to prevent the dotting pen from detaching from the connecting frame.

[0016] In one embodiment of the present invention, the buffer assembly includes a first buffer member and a second buffer member;

[0017] The first buffer member includes a first guide rod fixed on the connecting frame, a mounting plate fixed on the top of the first guide rod, and a first elastic member sleeved on the first guide rod;

[0018] A buffer plate is fixedly provided on the top of the guide sleeve above the connecting frame. The buffer plate is slidably assembled on the first guide rod, and the first elastic member is located between the buffer plate and the mounting plate.

[0019] In one embodiment of the present invention, the second buffer member includes a second guide rod fixed on the mounting plate, a limit cover plate fixed on the top of the second guide rod, and a second elastic member sleeved on the second guide rod;

[0020] A connecting plate is fixedly provided on the top of the dotting pen. The connecting plate is slidably assembled on the second guide rod, and the second elastic member is located between the connecting plate and the limiting cover plate.

[0021] Through the above technical solution, the first buffer member and the second buffer member work together to play a buffering role; when the dotting pen marks a higher type of PCB board, the dotting pen slides upward after contacting the PCB board, the buffer plate squeezes the first elastic member, and the connecting plate squeezes the second elastic member; when the dotting pen finishes marking the higher type of PCB board, the rebound characteristics of the first elastic member and the second elastic member cause the dotting pen to slide downward to its initial position, thereby improving the diversity of the device and making it suitable for marking PCB boards of different heights.

[0022] In one embodiment of the present invention, a first mounting bracket is fixedly mounted on the rotating bracket, a CCD camera is fixedly mounted on the first mounting bracket, and the CCD camera is tilted.

[0023] Through the above technical solution, the CCD camera is used to image the quality of the PCB board for easy inspection.

[0024] In one embodiment of the present invention, second mounting brackets are fixedly mounted on the rotating brackets on both sides of the two dotting pens, and lighting lamps are mounted on both of the second mounting brackets.

[0025] Through the above technical solution, the lighting lamp is used to increase the brightness, making the CCD camera image clearer.

[0026] As described above, the dotting pen device with dual dotting functions of the present invention has the following beneficial effects:

[0027] 1. Two dotting mechanisms with different marking colors are used to mark defective products that need to be retested and defective products that are directly scrapped, thereby distinguishing different types of defective products. This provides strong support for quality traceability and process optimization, helps to continuously improve the inspection process and meet diverse production needs;

[0028] 2. The first buffer member and the second buffer member work together to play a buffering role; when the dotting pen marks a higher type of PCB board, the dotting pen slides upward after contacting the PCB board, the buffer plate squeezes the first elastic member, and the connecting plate squeezes the second elastic member; when the dotting pen finishes marking the higher type of PCB board, the rebound characteristics of the first elastic member and the second elastic member cause the dotting pen to slide downward to its initial position, thereby improving the diversity of the device and being suitable for marking PCB boards of different heights.
