Technical Field

[0001] This utility model relates to the field of screw-driving device technology, specifically to a horizontal automatic screw-driving mechanism. Background Technology

[0002] In the field of automated processing technology, screw-driving equipment is a common type of equipment. Existing screw-driving equipment is generally vertical, which is used to fasten screws on the top of the product. Screws in the horizontal position still need to be fastened manually, which is time-consuming and labor-intensive. Moreover, during the fastening process, the fastening depth is often insufficient, resulting in the product not being assembled securely. If the existing vertical screw-driving equipment is placed horizontally, it occupies a lot of space and is difficult to use. Utility Model Content

[0014] Furthermore, the screw-driving device also includes a receiving joint, which is provided with a screw feeding channel and a locking channel for the passage of the end of an electric screwdriver.

[0015] The advantage of adopting the above technical solution is that the screws are automatically fed through the screw feeding channel, and then the electric screwdriver is fastened through the fastening channel, ensuring that the screws are fastened in place and improving the product yield.

[0016] Furthermore, the second moving device includes a base plate, a moving plate, and a cylinder. The cylinder is mounted on the base plate, and its output end is connected to the moving plate to drive the moving plate to move. The first moving device is connected to the moving plate.

The driving component 14 is mounted on the first fixed plate 11 and fixed to the first fixed plate 11 by a support frame. It is used to provide power to drive the slider 13 to move on the slide rail 12. At the same time, there are two sliders 13, both of which are mounted on the slide rail 12.

[0039] Furthermore, the driving component 14 is a motor, which can be a servo motor. Its output end is connected to a first synchronous pulley 15. A second synchronous pulley 16 and a synchronous belt are provided on the first fixed plate 11. The second synchronous pulley 16 is rotatably fixed on the first mounting plate 34. The synchronous belt connects the two synchronous pulleys. A connecting block 4 connected to the slider 13 is provided on the synchronous belt. The connecting block 4 is fixedly installed with the slider 13. The motor drives the first synchronous pulley 15 to rotate, which in turn drives the synchronous belt to rotate. Furthermore, the connecting block 4 drives the slider 13 to move, thus moving the entire electric screwdriver 1.

[0040] Furthermore, the screw-driving device also includes a receiving joint 5, which is provided with a screw feeding channel 51 and a locking channel 52 for the end of the electric screwdriver 1. The entire receiving joint 5 is fixedly installed to the first fixed plate 11 by a support plate. Its locking channel 52 is connected to a feeding pipe, a vibrating plate, etc. to realize automatic feeding. At the same time, a sensor is also set in the receiving joint 5 to sense whether the screw is in position. A laser sensor can be used to realize this. After the screw is fed, the screwdriver bit 17 of the electric screwdriver 1 enters the locking channel 52 and drives the screw to rotate and lock. The electric screwdriver 1 is an intelligent electric screwdriver 1, which realizes torque control and has higher precision and stability. Its structure and working principle are existing technologies and will not be described here.

The cylinder 33 is mounted on the base plate 31, and its output end is connected to the moving plate 32 to drive the moving plate 32 to move. Guide rails and sliders 13 are also provided on both sides of the cylinder 33 to provide support and guidance. The first fixed plate 11 is fixedly connected to the moving plate 32 to achieve installation and fixation. The moving direction of the second moving device 3 is the same as that of the first moving device 2. A moving module is fixed on the lower side of the base plate 31 to realize the movement of the entire device in the x, y, and z axes, which is convenient to use. The moving module can be selected as a linear module, a lead screw motor module, or a moving platform, and the position is controlled by a motor lead screw to realize the movement of the entire device.

[0042] Furthermore, mounting plates 34 are provided on both sides of the base plate 31, and hydraulic buffers 35 are fixed on the mounting plates 34. The hydraulic buffers 35 are standard parts and play a buffering role to ensure safe use.

[0043] Furthermore, the position sensing device includes a displacement sensor 6 disposed on the side of the first fixing plate 11, used to sense the tightening depth of the electric screwdriver 1. The linear displacement sensor 6 can be capacitive, magnetic, optical, or pressure-based.

[0045] In some embodiments, the screw-driving device further includes an elastic component, including a guide shaft 7 and connecting plates 71 at both ends. A spring 72 is fitted onto the guide shaft 7. The two connecting plates 71 are respectively connected to the electric screwdriver 1 and the slider 13. One end of the guide shaft 7 slides within the connecting plate 71. At this time, the slider 13 on the slide rail 12 is divided into a first slider 131 and a second slider 132, both sliding on the slide rail 12. The connecting plates 71 are fixed to the first slider 131 and the second slider 132 respectively, and a timing belt is connected and fixed to the second slider 132. The connecting plate 71 located on the first slider 131... The guide shaft 7 is provided with a through hole, and one end of the guide shaft 7 can slide inside the through hole but will not slide out of the through hole. The other end of the guide shaft 7 is fixedly installed on the connecting plate 71 fixed on the second slider 132. At the same time, a limit block 73 is provided on the guide shaft 7 to limit the position of the spring 72, so that there is a certain elasticity between the first slider 131 and the second slider 132. During the process of the screwdriver bit 17 pressing and rotating the screw, there is a certain buffering force, which ensures that the external thread of the screw matches the internal thread of the product to be installed during the tightening process, avoiding stripping and other situations, and ensuring installation quality.

[0046] During use, the screw is first fed into the connector 5 via automatic feeding, with its tail protruding and aligned with the device to be fastened. At this time, the first moving device 2 moves the screwdriver bit 17, pressing the screw head into the connector 5 and keeping the screw in a fixed position. Then, the second moving device 3 moves, bringing the screw to the fastening position. At this time, the electric screwdriver 1 rotates while the first moving device 2 continues to move. During this process, the displacement sensor 6 senses the fastening depth of the electric screwdriver 1, completing the fastening and ensuring the fastening quality.

[0047] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
