Technical Field

[0001] The utility model relates to the technical field of automatic screw feeding devices, in particular to a silo structure. Background Art

[0002] In the construction of communication networks, various RF cavity filters, combiners, duplexers, and multiplexers are widely used. As the scale of wireless communication infrastructure continues to expand, the demand for these components is also increasing. The production of these components requires the installation of a large number of screw parts. As production labor costs continue to rise, automated production is needed to improve production efficiency and reduce production costs. Communication device suppliers that produce these components require automated assembly equipment for production and manufacturing.

[0003] In the industry's existing automatic screw assembly equipment, vibrating plates or automatic silos are typically used to straighten the screws to achieve automatic feeding. However, these plates and automatic silos cannot identify the direction of the screws, nor can they feed screws of various specifications one by one in the required order. Therefore, current automatic screw assembly equipment also requires a robotic arm to grasp screws of different lengths and specifications one by one, and a visual recognition system to identify the screw's direction. This results in a very complex feeding system, difficult design techniques, complex control software, high manufacturing costs, and high equipment prices. For smaller communication device suppliers with smaller production quantities, purchasing such high-priced equipment makes it difficult to achieve economic benefits. Utility Model Content

The main body 31 and the cover plate 37 form a complete channel. The telescopic arm 3012 can support the cover plate 37. The driving cylinder 35 cooperates with the sliding bar 36 to control the manifold 3 to discharge materials. The sliding bar 36 drives the first protrusion 3010 to move, and cooperates with the second protrusion 3011 to make the manifold 3 shake.

[0028] See also Figure 5 and Figure 6The outside of the body 31 is connected to a blowing interface 38, and the outside of the blowing interface 38 and the exhaust interface 1012 are equipped with an air pump. The blowing interface 38 can speed up the discharge of the material inside the manifold 3. The bottom of the body 31 is connected to a discharge pipe 4, and the bottom of the discharge pipe 4 is connected to a hose. The discharge pipe 4 is convenient for connecting the manifold 3 with the external machinery for feeding. The top of the inlet hole 33 is connected to the delivery pipe 2, and the delivery pipe 2 is connected to the silo mounting plate 5 through a clamp. The number of delivery pipes 2 matches the number of inlet holes 33, and the clamp can reduce the shaking of the delivery pipe 2. The outside of the automatic feeding bin 1 is equipped with a controller, and the controller is connected to the full-material sensing optical fiber 1014, the direction identification optical fiber 1013 and the optical fiber group 34. The controller can control the feeding and discharging of the screw through the full-material sensing optical fiber 1014, the direction identification optical fiber 1013 and the optical fiber group 34. The telescopic arm 3012 includes a sleeve and a slide rod. The slide rod is slidably arranged inside the sleeve, and a spring is connected between the slide rod and the sleeve. The slide rod and the sleeve are respectively connected to the silo mounting plate 5 and the cover plate 37. The spring cooperates with the slide rod and the sleeve to enable the telescopic arm 3012 to guide the manifold 3 and return it.

[0029] In this solution, the screw is placed inside the automatic feeding bin 1, and the first push plate 14 is driven to descend to the bottom, and the screw is accumulated just above the first push plate 14;

[0030] The first push plate 14 is driven to rise, and the screw lying on the top of the first push plate 14 is lifted up to perform stacking. At this time, the skewed and upright screws fall back into the interior of the automatic feeding bin 1, and the second push plate 15 is lowered.

[0031] The first push plate 14 rises to the top, and the second push plate 15 descends to the bottom. The screw at the top of the first push plate 14 slides obliquely downward to the top of the second push plate 15. At this time, due to the obstruction of the rotatable blocking block 19, only one screw reaches the top of the second push plate 15. The second push plate 15 rises, the first push plate 14 descends, and when the second push plate 15 rises to the top, one end of the screw is aligned with the direction recognition optical fiber 1013, and then the reverse direction of the screw is recognized according to the groove at one end of the screw, and the recognition signal is transmitted to the control system inside the device;

[0032] When the screw is in the correct direction, the release electromagnet 1011 moves, pushing the rotatable blocking block 19 to rotate, so that its top moves away from the second push plate 15, and then the screw on the top of the second push plate 15 slides into the interior of the conveying pipe 2;

[0033] When the screw is in the reverse direction, the exhaust port 1012 is blown by an external air pump, which then causes the screw to move and fall into the interior of the automatic feeding bin 1 through the reflux guide plate;

[0034] When the outlet at the bottom of the automatic feeding bin 1 is closed by the blocking electromagnet 1016, the forward screws accumulate at the outlet inside the automatic feeding bin 1 for standby use, and the accumulated amount keeps increasing. When a screw stops at the full material sensing optical fiber 1014, the control system inside the automatic feeding bin 1 should stop the first push plate 14 and the second push plate 15 inside the automatic feeding bin 1 from working, thereby stopping the discharge of materials.

[0035] The screw inside the automatic feeding bin 1 enters the interior of the inlet hole 33 through the conveying pipe 2, and then enters the interior of the confluence groove 32. When the screw slides to the outside of the optical fiber group 34, the optical fiber group 34 controls the driving cylinder 35 through the control system inside the automatic feeding bin 1 to move, and then drives the sliding bar 36 to release the seal of the confluence groove 32. At the same time, the air blowing interface 38 exhausts the interior of the optical fiber group 34 through an external air pump, drives the screw to discharge the material, and sends it to the screw assembly equipment through the discharge pipe 4;

[0036] When the sliding bar 36 moves, it drives the T-shaped block 39 to move together, and then collides with the second protrusion 3011 through the first protrusion 3010, so that the entire convergence plate 3 shakes, thereby preventing the screw from accumulating inside the convergence groove 32, the conveying pipe 2 and the discharge pipe 4 and preventing normal discharge.
