Description

Technical Field

[0001] The utility model relates to the technical field of screw driving machines, in particular to an automatic screw driving machine feeding structure. Background Art

[0002] The automatic screw driving machine is designed under PLC software. Its control function is very powerful. The equipment system can be customized according to the actual situation of the customer's products to meet the quality and efficiency requirements of industrial automation, which is convenient for reducing manpower, improving efficiency, and ensuring product quality. Through automated operation methods, it comprehensively improves the production efficiency, quality control and management level of various products, provides customers with high quality, reduces costs and creates higher profits. Therefore, it is widely used. In the use of the automatic screw driving machine, a screw automatic feeding device is required.

[0003] As disclosed in Chinese patent announcement number (CN220498355U), an automatic feeding device for screws of a screw driving machine comprises a base, a box body fixedly connected to the top of the base, two mounting seats fixedly mounted on the bottom wall of the box body, and a PLC controller fixedly mounted on the left side of the box body. The outside of the box body is provided with a rotating mechanism extending into the interior thereof, and the interior of the mounting seat on the right side is provided with a conveying and correcting mechanism. The rotating mechanism comprises a servo motor fixedly mounted on the top of the box body and a rotating shaft rotatably connected to the inside of the box body. The automatic feeding device for screws of a screw driving machine starts the servo motor through the PLC controller, and the servo motor drives the main bevel gear to rotate. The main bevel gear rotates and meshes with the secondary bevel gear and drives the rotating shaft to rotate. The rotation of the rotating shaft drives the mounting plate to rotate, which is convenient for switching the clamping mechanism and the screw driving mechanism. The combined use of the rotating mechanism, the clamping mechanism and the screw driving mechanism achieves the advantage of convenient feeding.

[0004] However, as in the above patent, there is still a problem of poor feeding and sorting accuracy of the automatic screw driving machine. For example, in the above patent, the advantage of easy loading is achieved by combining a rotating mechanism, a clamping mechanism and a screw driving mechanism, and a conveyor belt structure is used to move the screws to a specified position, and the clamping mechanism is used to pick up the material. The conveyor belt in this method can only play a conveying role and cannot ensure that the screws are in a uniform direction. The clamping structure has no correction function, which may easily cause the screws to fail to be fed normally and inserted into the mounting hole during use, affecting processing efficiency.

The ends are fixed to the side opposite to the movable frame 34 and the outer cover 33 respectively, and the electromagnet 35 is fixed between the side opposite to the four spring sheets 36. The electromagnet 35 is activated to transmit pulse vibration through the spring sheets 36, and the movable frame 34 drives the top plate 37 to cooperate with the spiral feeding belt to transport the internal screws to the specified position through spiral vibration.

[0024] In this embodiment, a controller is fixed on the front of the screw driving machine body 2, a spiral feeding belt is fixed on the inner wall of the top plate 37, and the top of the spiral feeding belt is fixed to the return hopper 38.

[0025] See also Figure 3In order to pull and feed the screws during the feeding process, the adjustment component 4 in this embodiment includes a support frame 41, a conveyor belt 42, a connecting frame 43, a partition 44 and a traction magnet 45. The screws are conveyed to the top of the conveyor belt 42 through the feeding belt 39.

The length of the traction magnet 45 is equal to the width of the feeding belt 39.

[0027] The working principle of the above embodiment is:

[0028] (1) When the screw driving machine is used for sorting and feeding, the screws are poured into the top plate 37 of the feeding mechanism 3 by manual or other automatic means. The four vibration-damping feet 32 ​​reduce the vibration during the feeding process to ensure the stability of the screw positioning. The electromagnet 35 is activated and transmits pulse vibration through the spring plate 36. The movable frame 34 drives the top plate 37 to cooperate with the spiral feeding belt to transport the internal screws to the specified position through spiral vibration. The screws can usually naturally adjust to the same direction during the vibration process. The sorted screws fall into the return hopper 38 through the top plate 37, and then are transported to the side of the screw driving machine body 2 through the feeding belt 39 for the screw driving machine body 2 to take the material for processing. The U-shaped cross-section of the feeding belt 39 and the screw rod limit opening on the inner bottom wall ensure that the screws maintain the correct direction and posture during the transportation process. The interception piece inside the return hopper 38 is an adjustment trap for feeding the screws in the correct direction. The rest fall back into the top plate 37 and are re-vibrated and sorted to ensure that only screws are fed into the feeding belt 39.

[0029] (2) When the screws are pulled and fed during the feeding process, the screws are transported to the top of the conveyor belt 42 through the feeding belt 39. The adjustment component 4 is responsible for sending the screws from the feeding mechanism 3 to the locking position of the screw driving machine body 2. The traction magnet 45 is activated and the screws are magnetically attracted to ensure that the screws will not roll or be misplaced during the feeding process. As the conveyor belt 42 moves, the screws attracted by the traction magnet 45 continue to move along the feeding belt 39 to the locking position. There are several connecting frames 43, which are evenly distributed along the length of the conveyor belt 42 to provide uniform support and ensure the stable operation of the conveyor belt 42. Through the precise control of the adjustment component 4, the screws are prevented from getting stuck in the middle due to the reduction of vibration force transmission during the screw feeding process, and the screws can be accurately sent to the locking position of the screw driving machine body 2 to prepare for the next locking operation. When the screws reach the specified position, the screw driving machine body 2 takes the material to complete the last step of the feeding process. The above steps are repeated to achieve continuous screw feeding operation.
