Description

Technical Field

[0001] This invention relates to the field of pin processing technology, specifically to an automatic pin vibratory feeder device. Background Technology

[0002] In the automotive manufacturing, 3C electronics, and precision machinery industries, pins are fundamental connecting components, and the requirements for feeding efficiency and precision in their production and processing are continuously increasing with industrial upgrading. With the popularization of automated production lines, traditional manual feeding methods are no longer suitable for modern mass production needs due to their high labor intensity, low efficiency (requiring 2-3 workers to operate in shifts on a single production line), and large fluctuations in feeding accuracy (manual placement positioning error can reach ±0.5mm). Vibratory feeders, as the core equipment for automatic feeding of small parts, have become the mainstream choice for automated pin feeding due to their advantage of enabling orderly arrangement and transportation of parts. Existing adjustable pin vibratory feeder devices mostly adopt a manual bolt tightening adjustment structure. The angle is adjusted by prying the feed trough and then fixed with bolts. This not only results in poor adjustment accuracy (angle error can reach ±5°), but also makes it impossible to accurately connect with the feed inlet of subsequent CNC machining and automatic pressing equipment. Furthermore, it can only adapt to pins with a diameter range of ±1mm. If it is necessary to adapt to larger specifications, the entire feed trough and support components need to be disassembled and replaced. This operation is cumbersome and time-consuming, and the cost of a single replacement can be as high as several hundred yuan. Frequent switching significantly increases the production cost of enterprises.

[0003] Therefore, the present invention provides an automatic feeding device for a pin vibratory feeder. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-5 An automatic feeding device for a pin vibratory feeder includes a vibratory feeder body 1, a feeding trough 2 provided at the discharge end of the vibratory feeder body 1, and an adjustment mechanism 3 provided between the vibratory feeder body 1 and the feeding trough 2. The adjusting mechanism 3 includes a stabilizing plate 31, with a moving groove 32 inside the stabilizing plate 31. A lead screw 35 is rotatably connected inside the moving groove 32. A moving block 36 is threadedly connected to the outside of the lead screw 35. A connecting plate 37 is fixedly connected to the outside of the moving block 36. A first rotating groove 38 is fixedly connected to the outside of the connecting plate 37. A support rod 39 is rotatably engaged inside the first rotating groove 38. A second rotating groove 310 is fixedly connected to the bottom of the feeding trough 2.

[0022] Furthermore: the stabilizing plate 31 is fixedly connected to the bottom of the discharge end of the vibratory feeder body 1; the lead screw 35 is rotatably connected to the inside of the moving groove 32 via the rotating handle 34; the moving block 36 has a threaded hole inside; the lead screw 35 is threadedly connected to the inside of the moving block 36; the top of the rotating handle 34 passes through the movable tube 33 and is fixedly connected to the bottom of the lead screw 35; and the outer side of the rotating handle 34 is covered with an anti-slip rubber sleeve; the outer surface of the anti-slip rubber sleeve has a diamond-shaped anti-slip texture; the connecting plate 37 is slidably connected to the outer side of the stabilizing plate 31 via the moving block 36; and the connecting plate 37 and the outer side of the stabilizing plate 31 are in close contact with each other.

[0023] Working principle: The stabilizing plate 31 is installed at the bottom of the discharge end of the vibratory feeder body 1 through a fixed structure. The mounting plate 21 on the outer side of the top of the feeding trough 2 is connected to the outer side of the discharge end of the vibratory feeder body 1 by a hinge connection and is initially fixed by the fixing bolt in the waist-shaped adjustment hole, so that the inlet end of the feeding trough 2 and the discharge end of the vibratory feeder body 1 are initially connected. In the adjustment mechanism 3, the screw 35 is rotatably connected in the moving groove 32 of the stabilizing plate 31. Its bottom end passes through the movable tube 33 and is fixed with the rotating handle 34. The moving block 36 is threadedly connected to the screw 35 through the internal threaded hole, and the connecting plate 37 on the outer side of the moving block 36 is tightly attached to the outer side of the stabilizing plate 31. The two ends of the support rod 39 are respectively rotatably locked in the first rotating groove 38 and the second rotating groove 310, forming the support adjustment structure of the feeding trough 2. When the angle and height of the feed trough 2 need to be adjusted according to the pin specifications or the position of subsequent processing equipment, the operator holds the rotating handle 34, which is fitted with an anti-slip rubber sleeve, and rotates it. The rotating handle 34 drives the lead screw 35, which is fixed at the top, to rotate within the moving groove 32. Because the thrust bearing between the top of the lead screw 35 and the inner top wall of the moving groove 32 reduces rotational friction, it ensures that the lead screw 35 rotates smoothly. When the lead screw 35 rotates, the moving block 36, which is threaded to it, is restricted by the guide structure inside the moving groove 32 and moves up and down along the axial direction of the lead screw 35. Simultaneously, the connecting plate 37 on the outside moves synchronously. When the connecting plate 37 moves, it pulls or pushes the support rod 39 through the first rotating groove 38. The other end of the support rod 39 drives the feeding groove 2 to rotate around the hinge connection point between the mounting plate 21 and the vibrating plate body 1 through the second rotating groove 310, thereby realizing the angle adjustment of the feeding groove 2. If it is necessary to finely adjust the docking gap between the feeding groove 2 and the vibrating plate body 1, the fixing bolt in the waist-shaped adjustment hole of the mounting plate 21 can be loosened, the feeding groove 2 can be moved laterally to the appropriate position, and then the bolt can be tightened again to complete the precise adjustment. After adjustment, the vibratory feeder body 1 is started. The vibratory feeder body 1 arranges the pins in an orderly manner and conveys them to the discharge end through the internal vibration structure. The pins enter the feeding trough 2 from the discharge end. The polytetrafluoroethylene wear-resistant liner on the inner wall of the feeding trough 2 can reduce friction loss during pin conveying and prevent scratches on the pin surface. The arc transition surface on the inner side of the liner can guide the pins to slide smoothly and prevent the pins from getting stuck at corners. During the pin conveying process, the connecting structures of the adjustment mechanism 3 always remain stable, and the triangular weld between the stabilizing plate 31 and the movable tube 33 is stable. The reinforcing ribs enhance the load-bearing capacity of the adjustment mechanism 3, preventing structural deformation caused by the weight of the feeding trough 2 and the pins. The wear-resistant washers on the inner sides of the first rotating groove 38 and the second rotating groove 310 can reduce the wear of the support rod 39 during rotation and extend the service life of the components. At the same time, the tight fit design of the connecting plate 37 and the stabilizing plate 31, as well as the bolt or welding fixation between the components, ensure that the entire device remains secure in the vibratory environment of the vibratory feeder body 1, ultimately achieving continuous, stable, and automatic feeding of the pins from the vibratory feeder body 1 to the subsequent processing equipment.

[0024] Please see Figure 1-5In one embodiment, a wear-resistant liner is fixedly connected to the inner wall of the feeding trough 2. The wear-resistant liner is made of polytetrafluoroethylene (PTFE), and the inner wall of the wear-resistant liner has an arc transition surface. The moving block 36 is slidably connected to the inside of the moving trough 32. A reinforcing rib is fixedly connected to the outer side of the movable tube 33. One end of the reinforcing rib is fixedly connected to the bottom of the stabilizing plate 31. The reinforcing rib has a triangular structure, and the connection between the reinforcing rib and the stabilizing plate 31 and the movable tube 33 is welded. The top end of the lead screw 35 is connected to the moving trough 32. A thrust bearing is installed between the inner top walls. The inner ring of the thrust bearing is fixedly connected to the outer side of the lead screw 35, and the outer ring of the thrust bearing is fixedly connected to the inner top wall of the moving groove 32. The first rotating groove 38 and the connecting plate 37, and the second rotating groove 310 and the feeding groove 2 are all fixedly connected by bolts. Wear-resistant washers are fixedly connected to the inner walls of the first rotating groove 38 and the second rotating groove 310. The end of the support rod 39 away from the first rotating groove 38 is rotatably engaged inside the second rotating groove 310.

[0025] Please see Figure 1-5 In one embodiment, the vibratory feeder body 1 will vibrate when it is working. A shock-absorbing pad is added at the connection between the stabilizing plate 31 and the bottom of the discharge end of the vibratory feeder body 1. The shock-absorbing pad is made of nitrile rubber with a thickness of 5-8mm and has honeycomb-shaped ventilation holes inside. This can reduce the vibration transmitted from the vibratory feeder body 1 to the adjustment mechanism 3, prevent the lead screw 35 and the moving block 36 from loosening due to vibration, and reduce the noise of the adjustment mechanism 3 during operation.

[0026] Please see Figure 1-5 In one embodiment, a movable tube 33 is fixedly connected to the bottom of the stabilizing plate 31, and a rotating handle 34 is rotatably engaged inside the movable tube 33. An mounting plate 21 is provided on the outer side of the top of the feeding trough 2, and the mounting plate 21 is rotatably and symmetrically distributed on the outer side of the discharge end of the vibratory feeder body 1.

[0027] Please see Figure 1-5 In one embodiment, the mounting plate 21 is connected to the outer side of the discharge end of the vibratory feeder body 1 by a hinge connection, and the outer side of the mounting plate 21 is provided with a waist-shaped adjustment hole. A fixing bolt is inserted inside the waist-shaped adjustment hole, and one end of the fixing bolt passes through the waist-shaped adjustment hole and is threadedly connected to the outer side of the vibratory feeder body 1.

[0028] Please see Figure 1-5To further improve the speed of the feeding device, in one embodiment, the top to center of the feeding trough 2 is designed as an opening, with a rotating shaft 25 at both ends of the opening. A conveyor belt 23 is sleeved on the shaft of the rotating shaft 25. Rubber protrusions 22 are evenly spaced along the horizontal direction on the conveyor belt 23. The length of the top view of the rubber protrusions 22 matches the length of the top view of the conveyor belt 23. A motor 24 is installed on the back of the feeding trough 2 near the mounting plate 21. The output shaft of the motor 24 passes through the inner cavity of the feeding trough 2 and is connected to the rotating shaft 25 near the mounting plate 21.

[0029] Working principle: When in use, the motor 24 is energized, causing it to drive the rotating shaft 25 to rotate, thereby allowing the conveyor belt 25 to rotate on the two rotating shafts 25. The side of the conveyor belt 25 closest to the mounting plate 21 has multiple rubber protrusions 22 that can lock the pins rolling on the conveyor belt 25 (enhancing its resistance and friction). Thus, the rotation speed of the rotating shaft 25 can be controlled by adjusting the power input to the motor 24, thereby achieving the purpose of controlling the conveying efficiency of the conveyor belt 25.
