Description

Technical Field

[0001] This utility model relates to the field of screw machine technology, and more specifically to a screw adsorption structure for screw machines. Background Technology

[0002] A screw fastening machine is a small, automated machine for tightening screws. Its operating structure can generally be divided into two parts: a feeding section and an electric screwdriver section. The feeding section is responsible for screening and providing screws, while the electric screwdriver section is responsible for picking up and tightening the screws. The emergence of screw fastening machines has improved work efficiency and reduced the intensity of manual labor. It is an automated device that replaces manual labor in picking up, placing, and tightening screws. With slight modifications, it can also be used for the automatic assembly of small cylindrical parts. It has been widely used abroad, and many domestic enterprises have a very broad application prospect.

[0003] Insufficiency of existing technology: The air blowing device of existing screw machines may cause uneven airflow distribution, resulting in unstable screw positioning, or the air blowing force may be too strong or too weak, causing the screw to fail to be accurately adsorbed or over-push. Moreover, the scattered airflow may interfere with other screws or assembly parts, and even affect the normal operation of other production equipment. Furthermore, if the adsorption of the screw is not firm, the screw may fall or deviate from the track during the conveying process, affecting the smooth progress of the installation process. Or, due to unstable airflow or the shape of the screw itself, the screw may be deviated during adsorption, affecting the subsequent installation accuracy. Utility Model Content

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by incorporating an air blowing and suction mechanism, facilitates precise screw positioning, avoids inaccurate screw placement due to external interference, and ensures the accuracy of screw entry into the target hole. The air blowing and suction process maintains consistency each time, ensuring that each screw is accurately and stably assembled into the correct position. The air blowing and suction devices can precisely control the force and direction of the airflow, thereby reducing any errors in the screw guiding process and ensuring accurate assembly. The size, direction, and suction force of the airflow can be adjusted to accommodate screws of different specifications, shapes, and materials, improving the flexibility of the production line and enabling rapid switching between different types of product production.

[0014] 2. This utility model, by incorporating a screw fixing mechanism, effectively secures screws to the machine's assembly head, preventing them from falling or deviating from their target position during handling, conveying, or assembly. Combined with the air-blowing and screw-fixing mechanisms, the entire screw assembly process becomes more automated, thereby improving the automation level of the production line, reducing manual operation, and increasing production efficiency and quality. The fixing mechanism, by securing the screws, prevents positional deviations during assembly, effectively improving assembly accuracy and reducing assembly errors. Because the screw fixing mechanism effectively prevents screws from falling or being damaged, it reduces waste caused by lost or damaged screws, thus lowering production costs.

[0026] The fixing mechanism 2 includes a protective ring 201 and a gripping flap 202. A moving rail 203 is fixedly connected to the side of the gripping flap 202, and an annular magnet 204 is fixedly connected to the inside of the gripping flap 202. A slot 205 is opened on the inside of the gripping flap 202, and the inside of the slot 205 is connected to the side of the screw 208. A guide groove 206 is opened on the side of the protective ring 201, and the inside of the guide groove 206 is connected to the side of the rebound mechanism 3.

[0027] The gripper 202 has a fixing groove 207 on its side, the inner side of the slot 205 is fixedly connected to the side of the annular magnet 204, the side of the screw 208 is connected to the inner side of the conveying pipe 101, the top of the protective ring 201 is fixedly connected to the bottom of the outer frame mechanism 4, the top of the gripper 202 is fixedly connected to the top of the protective ring 201, and the side of the moving rail 203 is connected to the side of the rebound mechanism 3.

[0028] The rebound mechanism 3 includes a roller 301 and a spring 307. The roller 301 has a guide ring groove 302 on its side. The inner side of the guide ring groove 302 is connected to the side of the moving rail 203. The side of the roller 301 is connected to the side of the gripper 202. An I-shaped rotating rod 303 is fixedly connected to the inner side of the roller 301. A support plate 304 is connected to the side of the I-shaped rotating rod 303.

The bottom end of the guide rod 306 is connected to the inner side of the guide groove 206. The bottom end of the elastic spring 307 is fixedly connected to the side of the protective ring 201. The inner side of the elastic spring 307 is connected to the side of the guide rod 306.

[0030] The outer frame mechanism 4 includes a storage tube 401, a built-in screwdriver 402 fixedly connected to the side of the storage tube 401, a fixed handle 404 fixedly connected to the top of the storage tube 401, the side of the fixed handle 404 fixedly connected to the side of the fixed ring 106, a moving groove 403 opened on the side of the storage tube 401, the inner side of the moving groove 403 connected to the top of the conveying tube 101, and the bottom end of the storage tube 401 fixedly connected to the top of the protective ring 201.

[0031] The working principle of this utility model is as follows: When using the screwdriver, the screw 208 is transported to the inside of the conveying pipe 101 through the air supply pipe 104. When the screw 208 is at the bottom of the conveying pipe 101, it will be stuck on the inner wall of the moving groove 403. When the built-in screwdriver 402 fixes the first screw 208 and retracts, the conveying pipe 101 will move, and the screw 208 will slide from the bottom of the conveying pipe 101 to the bottom of the storage pipe 401 by gravity and fall to the bottom of the gripping petal 202. The screw 208 is stuck by the slot 205 at the bottom of the gripping petal 202. A ring magnet 204 is fixed on the inner side of the bottom of the gripping petal 202. The magnetic force will prevent the position of the screw 208 from flipping, reducing the probability of the screw 208 reversing.

[0032] After the built-in screwdriver 402 moves downward and takes away the screw 208 to fix it, it springs upward and the next screw 208 will slide to the inside of the gripper 202. Under the pressure of the built-in screwdriver 402, the moving rail 203 on the side of the gripper 202 compresses the spring spring 307, and after the screw 208 is removed from the gripper 202, the spring spring 307 rebounds and acts on the pressure plate 305, which drives the roller 301 to roll on the side of the moving rail 203 and return to the side of the gripper 202.

[0033] Furthermore, the blowing-type delivery method of the air supply pipe 104 would result in gas waste. Therefore, an air suction pipe 107 is fixed on the other side of the storage pipe 401 to perform air suction. The combined use of the air supply pipe 104 and the air suction pipe 107 can not only reduce gas waste, but also make the sliding of the screw 208 more stable, less prone to flipping, and reduce the need for subsequent adjustments by the staff.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
