[0034] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0035] like Figure 1-6As shown, a parts feeder includes a power component 2, a transmission component 3 and a support component 4 respectively arranged on a bracket 1, the transmission component 3 includes a rotating shaft 31, and a conveying trough 32 is provided on the periphery of the rotating shaft 31, the conveying trough 32 is spirally arranged, and the groove width of the spiral conveying trough 32 is not less than the width of the parts to be conveyed, the parts are placed in the conveying trough 32, a support portion is provided on the bracket 1, the periphery of the parts is overlapped on the support portion, the rotating shaft 31 and the support portion are arranged parallel to each other, the power component 2 is used to intermittently drive the rotating shaft 31 to rotate, and the rotating shaft 31 rotates intermittently 1 can drive the displacement of parts. The parts are rectangular sheet-like in shape. The parts in this embodiment are drone blades. The two ends of the parts are overlapped on the support parts on the bracket 1. The support parts are used to support the parts. The parts are always fitted in the conveying trough 32 due to gravity. Then, the spiral conveying trough 32 is used to make the parts move axially along the rotating shaft 31 to realize the step-by-step loading of the parts. During implementation, a mechanical hand is set on one side of the feeder to realize automatic feeding and loading, so as to complete the downstream operations in an orderly manner. The structure is simple, the production cost is low, the mechanical transmission is stable, and the reliability is high.

[0036] like Figure 5 and Figure 6 As shown, the power component 2 includes a first linear drive unit 21, and a rack 28 is installed at the execution end of the first linear drive unit 21, and the rotating shaft 31 is rotatably sleeved on the bracket 1, and a gear 33 is set at one end of the rotating shaft 31, and the gear 33 is engaged with one side of the rack 28. The execution end of the first linear drive unit 21 drives the gear 33 and the rotating shaft 31 to rotate by driving the rack 28. The length of the rack 28 is a mechanical control structure of the number of rotations of the rotating shaft 31, thereby achieving the same number of rotations of the rotating shaft 31 each time, thereby ensuring the accuracy of the equipment.

[0037] The first linear drive unit 21 is fixedly mounted to the execution end of the second linear drive unit 22, and the second linear drive unit 22 is fixedly connected to one side of the bracket 1. The second linear drive unit 22 can drive the rack 28 to move closer to or away from the gear 33. In order to reduce the equipment cost, the first linear drive unit 21 and the second linear drive unit 22 are both push rod cylinders, and the length of the rack 28 controls the number of rotations of the gear 33, which also ensures the transmission accuracy of the equipment.

[0038] The first linear drive unit 21 is fixedly connected to the support plate 23, and a slide rail 24 is provided on the support plate 23. A slider 25 is provided on one side of the rack 28. The lower end of the slider 25 is slidably connected to the slide rail 24, and one side of the slider 25 is fixedly connected to the execution end of the first linear drive unit 21.

[0039] The lower end of the support plate 23 is fixedly connected to the execution end of the second linear drive part 22, and the lower end of the support plate 23 is installed with a limit shaft 26. A limit seat 27 is provided on the second linear drive part 22. A limit hole is provided in the middle of the limit seat 27. The limit shaft 26 is slidably connected to the limit hole. The second linear drive part 22 is a reset structure of the rack 28, which is used to disengage the rack 28 from engagement with the gear 33. At the same time, in order to ensure the displacement stability of the support plate 23, a linear bearing is installed in the limit hole, and the limit shaft 26 is slidably connected to the linear bearing.

[0040] The working process of the power component 2: the first linear drive part 21 is the pushing part, and the push rod cylinder used is the pushing cylinder. The second linear drive part 22 is the lifting part, and the push rod cylinder used is the lifting cylinder. During the movement, the lifting cylinder is lowered, the gear 33 and the rack 28 are engaged, pushing the cylinder forward once, driving the screw to rotate one circle, the lifting cylinder is lifted, the gear 33 and the rack 28 are separated, pushing the cylinder back once, and then the lifting cylinder is lowered, the gear 33 and the rack 28 are engaged again, completing a complete action, repeating the above actions over and over again to complete the circular transportation of materials.

[0041] like Figure 1 and Figure 2 As shown, the support component 4 includes a support rod 41, a first sliding rod 11 is respectively arranged on both sides of the bracket 1, both ends of the support rod 41 are respectively slidably connected to a first sliding rod 11, a support rod 41 is respectively arranged on both sides of the rotating shaft 31, and the rotating shaft 31 and the support rod 41 are arranged parallel to each other to ensure the stability of the parts.

[0042] A limiting component 5 is also provided on the bracket 1, and the limiting component 5 includes two side panels 51, and a second sliding rod is provided on both sides of the bracket 1, and both ends of each side panel 51 are slidably connected to a second sliding rod, and the two side panels 51 are arranged parallel to each other. The part is located between the two side panels 51, and the two side panels 51 are used to limit the relative position of the part on the bracket 1 and the rotating shaft 31 to prevent the part from detaching from the bracket 1, and the side panels 51 are slidably connected to the bracket 1, which is convenient for adjusting the distance between the two side panels 51 and improving the applicability of the device.

[0043] A sliding hole is provided on both sides of the support rod 41 and on both sides of the side plate 51. The outer periphery of the first sliding rod 11 or the second sliding rod is located in the sliding hole, and a locking bolt is installed on the sliding hole. The locking bolt is used to fix the relative position of the support rod 41 and the first sliding rod 11, and the side plate 51 and the second sliding rod to prevent the side plate 51 and the support rod 41 from sliding relative to each other during use.

[0044] A gear 33 is fixedly installed at one end of the rotating shaft 31, and a boss 34 is provided at the other end of the rotating shaft 31, and the boss 34 is located at the outlet end of the spiral conveying trough 32. The boss 34 is used to lift the parts. The distance between the rotating shaft 31 and each support rod 41 is different, and after the boss 34 lifts the part, the part can rely on gravity to make one end tilt up. The horizontal heights of the two support rods 41 are different, and the height of the rotating shaft 31 is the same as the height of the higher support rod 41. The support rod 41 with low horizontality is used for auxiliary support of the parts. It can be used as an auxiliary when the shape of the parts is irregular or the quality of the two ends is different, so as to increase the applicability of the device.

[0045] During implementation, the robot or conveyor belt stacks the parts on the periphery of the rotating shaft 31. At this time, the periphery of the part is overlapped on the support rod 41 with a high horizontal height and the rotating shaft 31, and the part is supported by two points. The length of the rotating shaft 31 from the support rod 41 with a high horizontality is greater than the length of the rotating shaft 31 from the support rod 41 with a low horizontality. The part overlaps smoothly. As the first linear drive unit 21 drives the rack 28 to move, the gear 33 and the rotating shaft 31 rotate, thereby driving the part to move forward in a step-by-step manner. When the part drives out of the conveying trough 32, the part is lifted by the boss 34. At this time, the periphery of the part is overlapped on the periphery of the rotating shaft 31 and the periphery of the support rod 41 with a high horizontality, and the end of the part is restricted by the side plate 51, so that the part does not slip. The part to be picked up is separated from the subsequent parts by a certain angle. At this time, the external robot picks up the part without interference from other parts, and the position of the parts emitted by the feeder is consistent and stable.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
