Description

Technical Field

[0001] This utility model relates to the field of automated equipment production technology, specifically to an automatic screw feeding device. Background Technology

[0002] In the field of automated production, screws are core connectors, and the efficiency of their assembly process directly affects the overall production line's capacity. Traditional screw loading methods rely heavily on manual operation. Workers must manually sort and arrange screws before transporting them one by one to the assembly station. This is not only labor-intensive and costly, but also results in slow loading speeds and inconsistent cycle times. Furthermore, manual loading is prone to causing screws to bump or scratch, affecting product assembly accuracy.

[0003] Existing semi-automatic feeding equipment has many defects: some vibratory feeding devices adopt a rigid contact design, and screws are prone to wear due to collision during the conveying process, which will affect the performance of precision screws; some equipment feeding channels are prone to screw jamming and congestion, requiring frequent manual intervention to clean them; in addition, the feeding volume adjustment of the equipment is not flexible enough to adapt to different specifications and different assembly requirements of production scenarios, and its versatility is insufficient.

[0004] In response to the problems raised in the above article, we propose an automatic screw feeding device. Utility Model Content

[0009] According to the above-mentioned automatic screw feeding device, an electric telescopic rod is fixedly connected to one side of the auxiliary plate, and the output end of the electric telescopic rod is fixedly connected to the storage tank.

[0010] According to the above-mentioned automatic screw feeding device, a baffle is provided at the bottom of the auxiliary plate, and the baffle seals or opens the outlet end of the storage tank.

[0011] According to the above-mentioned automatic screw feeding device, an installation plate is fixedly connected inside the support frame, a second motor is fixedly connected to the bottom of the installation plate, a feeding plate is rotatably connected to the top of the installation plate, and the output end of the second motor is fixedly connected to the feeding plate.

[0012] According to the above-mentioned automatic screw feeding device, the shape of the feeding hopper is set to be wider at the top and narrower at the bottom.

[0013] According to the above-mentioned automatic screw feeding device, the inner wall of the electromagnetic flexible vibration platform is covered with a removable polyurethane flexible liner, and the polyurethane flexible liner has a grid-like micro-groove.

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] This invention utilizes an electromagnetic flexible vibration platform. When screws are conveyed within the platform, a removable polyurethane flexible liner on the inner wall directly contacts the screws, preventing rigid collisions. The mesh-like microgrooves on the polyurethane flexible liner buffer and guide the screws, reducing friction and scratches during conveying. Simultaneously, the feeding hopper features a design that is wider at the top and narrower at the bottom, allowing screws to slide smoothly from the feeding plate to the assembly station, avoiding impact damage upon drop and ensuring screw assembly accuracy. The speed of motor one can be adjusted via a control panel. Motor one, through gear engagement with a gear ring, drives an auxiliary disc to rotate, changing the screw conveying speed to adapt to different assembly rhythm requirements. An electric telescopic rod, with its output end driving the movement of the storage tank, allows for adjustment of the opening size of the storage tank's outlet, achieving precise control of the feeding amount and adapting to the feeding needs of screws of different specifications.

An operating table 5 is installed inside the support frame 1, an auxiliary disk 6 is rotatably connected to the top of the auxiliary frame 2, and an auxiliary component is installed at the top of the auxiliary frame 2. By using the auxiliary component, the feeding of screws of different specifications can be controlled, thereby improving the flexibility of the device.

[0026] The auxiliary components include a mounting frame 61, with a motor 62 fixedly connected to the top of the mounting frame 61. A gear 63 is rotatably connected to the top of the auxiliary frame 2. The output end of the motor 62 is fixedly connected to the gear 63. A gear ring 66 is fixedly connected to the outer side of the auxiliary disk 6, and the gear ring 66 meshes with the gear 63. Multiple storage tanks 65 are provided inside the auxiliary disk 6. Screws of different specifications can be filled into the multiple storage tanks 65 for subsequent use. An electric telescopic rod 64 is fixedly connected to one side of the auxiliary disk 6. The output end of the electric telescopic rod 64 is fixedly connected to the storage tank 65. The storage tank 65 can be moved by the electric telescopic rod 64, thereby dropping the screws inside the storage tank 65 into the electromagnetic flexible vibration platform 3. A baffle 67 is provided at the bottom of the auxiliary disk 6. The baffle 67 seals or opens the outlet end of the storage tank 65. The storage tank 65 is opened by the baffle 67, and the feeding speed is controlled.

[0027] An installation plate 72 is fixedly connected inside the support frame 1. A second motor 73 is fixedly connected to the bottom of the installation plate 72, and a feeding plate 71 is rotatably connected to the top of the installation plate 72. The output end of the second motor 73 is fixedly connected to the feeding plate 71. The feeding speed of the feeding barrel 7 is controlled by the second motor 73 and the feeding plate 71. The shape of the feeding barrel 7 is set to be wider at the top and narrower at the bottom.

When screws need to be transported, the corresponding storage tank 65 is moved by the electric telescopic rod 64, so that the baffle 67 opens the storage tank 65 and pours the screws down. The screws enter the electromagnetic flexible vibration platform 3. When the screws are transported in the electromagnetic flexible vibration platform 3, the detachable polyurethane flexible pads laid on its inner wall directly contact the screws to avoid rigid collisions. The grid-like micro-grooves on the polyurethane flexible pads can buffer and guide the screws, reducing friction and scratches during the transport process. Then, the screws are transported to the inside of the unloading bucket 7 through the cooperation of the feeding guide rail 8. The unloading speed of the screws is controlled by the cooperation of the motor 73 and the mounting plate 72, thereby improving the feeding requirements and increasing the flexibility of the device.
