Technical Field

[0001] This utility model relates to the technical field of surface mount fuse production equipment, and in particular to a scraper adjustment device for coating the terminal electrodes of a surface mount fuse. Background Technology

[0002] As a commonly used overcurrent protection component in electronic devices, the coating quality of the terminal electrodes of surface mount fuses directly affects the conductivity and service life of the product. In the production process of surface mount fuses, electrode paste needs to be evenly coated on both ends of the fuse body by a scraper device to form terminal electrodes. The scraper devices in the existing technology are usually fixed structures, and the angle and height are inconvenient to adjust, making it difficult to adapt to the coating requirements of surface mount fuses of different specifications and thicknesses.

[0003] Therefore, a scraper adjustment device for coating the terminal electrodes of surface mount fuses has been developed, which allows for easy adjustment of the height and angle of the scraper to meet the coating requirements of surface mount fuses of different specifications and thicknesses. Utility Model Content

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0019] A scraper adjustment device for coating the terminal electrodes of a surface mount fuse, such as Figures 1-5As shown, the assembly includes a worktable 1, rodless cylinders 2, a sliding frame 3, an adjusting frame 4, first guide rods 5, electric actuators 6, a mounting frame 7, a motor 8, a gear set 9, and a fixing component. Rodless cylinders 2 are connected to the front and rear sides of the upper part of the worktable 1. A sliding frame 3 is connected between the sliders 10 of the rodless cylinders 2. Two first guide rods 5 are slidably connected to the sliding frame 3. An adjusting frame 4 is connected between the lower sides of the first guide rods 5. An arc-shaped guide groove is opened on the adjusting frame 4. An electric actuator 6 is connected to the middle of the sliding frame 3. The telescopic end of the electric actuator 6 is connected to the adjusting frame 4. The mounting frame 7 is rotatably connected inside the adjusting frame 4. A motor 8 is connected to the right side of the adjusting frame 4. A gear set 9 is connected between the output shaft of the motor 8 and the mounting frame 7. A fixing component is provided on the mounting frame 7.

[0020] like Figure 4 and Figure 5 As shown, the fixing assembly includes a slider 10, a screw 11, a guide plate 12, a second guide rod 13, a fixing frame 14, and a scraper 15. The slider 10 is slidably connected to the right side of the adjusting frame 4, and the screw 11 is rotatably connected to the slider 10. The screw 11 is equipped with a knob for easy rotation. The second guide rod 13 is slidably connected to the upper right side of the mounting frame 7. The second guide rod 13 is slidably connected to the screw 11. The guide plate 12 is connected to the right side of the second guide rod 13. The guide plate 12 has an inclined guide groove. Two fixing frames 14 are slidably connected to the mounting frame 7. The fixing frames 14 are slidably engaged with the guide plate 12. A scraper 15 is engaged between the fixing frames 14. The upper part of the scraper 15 is located inside the mounting frame 7. The fixing frame 14 is equipped with a locking boss that engages with the scraper 15 and the mounting frame 7.

[0021] In use, the device is first placed at the electrode coating position of the patch fuse end. Then, the sliding frame 3 is moved laterally by the rodless cylinder 2 to adjust the scraper 15 to a suitable lateral position. By activating the electric push rod 6, the extension and retraction of the electric push rod 6 drives the adjusting frame 4 to move up and down along the first guide rod 5, thereby adjusting the height of the scraper 15 until the distance between the scraper 15 and the workpiece to be coated meets the requirements. By activating the motor 8, the motor 8 drives the mounting frame 7 to rotate through the gear set 9. At the same time, the slider 10 also slides along the arc-shaped groove on the adjusting frame 4 to adjust the tilt angle of the scraper 15 to adapt to different coating angle requirements. When the scraper 15 needs to be replaced, the screw 11 is rotated to drive the second guide rod 1. 3. The guide plate 12 is moved laterally. The guide plate 12 drives the two fixed frames 14 to move towards each other through the inclined guide groove. The clamping of the scraper 15 is loosened, and the old scraper 15 can be taken out. The new scraper 15 is placed between the two fixed frames 14. The screw 11 is rotated in the opposite direction to drive the fixed frames 14 to move relative to each other and clamp the scraper 15. Then the clamping bolt is tightened and the scraper 15 is pressed by the pressure plate to complete the replacement of the scraper 15. During the coating process, the rodless cylinder 2 drives the scraper 15 to move laterally. In conjunction with the conveying of the workpiece, the uniform coating of the end electrode paste is achieved. This makes it easy to adjust the height and angle of the scraper 15 to meet the coating needs of patch fuses of different specifications and thicknesses.
