Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 - Figure 5 As shown, this embodiment provides a micro-engraving machine for surface mount resistors, including a device body 1. The device body 1 contains a support frame 2. A lead screw 4 is installed inside the support frame 2, and an engraving table 10 is connected above the support frame 2. A collar 6 is fitted on the lead screw 4, and one end of the lead screw 4 is connected to a motor 5. One end of the collar 6 is connected to a mounting frame 7. A second lead screw 11 is installed inside the mounting frame 7. One end of the second lead screw 11 is connected to a motor 12, and a second collar 13 is fitted on the second lead screw 11. The front end of the second collar 13 is connected to... There is a connecting frame 14, a motor 15 is installed above the connecting frame 14, a lead screw 16 is connected below the motor 15, a connecting plate 17 is screwed onto the lead screw 16, an electric engraving needle 18 is fixedly installed in the connecting plate 17, a fixed frame 19 is provided above the engraving table 10, an electric push rod 20 is fixedly installed in the fixed frame 19, one end of the electric push rod 20 is connected to a clamp 21, a screw hole 22 is opened in the clamp 21, a threaded post 23 is screwed into the screw hole 22, and a pre-tightening plate 231 is connected below the threaded post 23.

[0024] Preferably, an anti-slip pad 3 is installed under the support frame 2. Multiple sets of anti-slip pads 3 are provided. The anti-slip pads 3 are fixedly connected to the support frame 2. By setting the anti-slip pads 3, the stability and anti-slip force of the support frame 2 are increased, ensuring the safety of the support frame 2 during use. A guide rod 9 is fixedly installed inside the support frame 2. A guide ring 8 is set below the mounting frame 7. The guide ring 8 is located on the left and right sides of the collar 6. The guide ring 8 is slidably connected to the guide rod 9. By setting the guide ring 8 and the guide rod 9, the direction of movement of the mounting frame 7 can be guided, avoiding the positional deviation of the mounting frame 7 during movement. A movable hole 24 is opened in the clamp 21. A slide rod 25 is slidably installed in the movable hole 24. The bottom of the slide rod 25 is fixedly connected to the pre-tightening plate 231. By setting the movable hole 24 and the slide rod 25, the connection and closeness between the devices are increased, avoiding the positional deviation of the pre-tightening plate 231 during use.

[0025] Preferably, two sets of slide rods 25 are symmetrically arranged. A limiting plate 26 is fixedly connected to the upper end of the slide rod 25. By setting the limiting plate 26, the slide rod 25 can be limited and fixed, preventing the slide rod 25 from coming off the movable hole 24 during use. A knob 27 is connected above the threaded column 23. An anti-slip groove 28 is provided in the knob 27. By setting the knob 27, the threaded column 23 can be rotated and adjusted. By setting the anti-slip groove 28, the user's hand is prevented from slipping when rotating the knob 27.

[0026] The working principle and process of this utility model are as follows: In use, the user places the product to be engraved between the clamps 21 and controls the electric push rod 20 to move. The electric push rod 20 drives the clamps 21 closer to the product to be engraved until both ends of the product are inserted into the clamps 21. Then, the user manually rotates the knob 27, which drives the threaded post 23 to rotate within the threaded hole 22. During the rotation of the threaded post 23, the pre-tightening plate 231 moves downwards. As the pre-tightening plate 231 moves downwards, it drives the sliding rod 25 to move within the movable hole 24 until the pre-tightening plate 231 is in close contact with the product to be engraved. Then, the user controls motor 5 to drive the lead screw 4 to rotate. When the lead screw 4 rotates, it drives the collar 6 and the mounting bracket 7 to move on the lead screw 4 until the electric engraving needle 18 moves above the product. Finally, the user controls motor 3 to drive the lead screw 3... When screw 16 rotates, it drives connecting plate 17 to move on screw 16. When connecting plate 17 moves, it drives electric engraving needle 18 to move downward. During the movement, the electric engraving needle 18 is controlled to engrave the product. Alternatively, motor 2 12 can be controlled to drive screw 2 11 to rotate. Screw 2 11 drives collar 2 13 to move on screw 2 11. When collar 2 13 moves, it drives connecting frame 14 and electric engraving needle 18 to move. During the horizontal movement, electric engraving needle 18 engraves the product below until the engraving is completed. It can clamp and fix the product to be engraved, which improves the applicability of the device, makes it convenient for users to limit the size of products, ensures the safety of the product during engraving, reduces the scrap rate of the product, and avoids the problem of the product shaking during the engraving process, which affects the engraving quality.
