Description

AUTOMATIC ROTOR FEEDING MECHANISM Technical Field of the Invention The present invention relates to an automation technology, and in particular to an automatic rotor feeding mechanism.

Background of the Invention A rotor includes a rotor shaft, a core fixed on the rotor shaft, and other parts. In the full-automatic production process, it is necessary to feed rotors one by one, during the assembly of parts on rotors or during the painting of cores on rotors.

In the existing rotor feeding mechanisms, the rotor often gets stuck, resulting in high failure rate. Moreover, by the existing rotor feeding mechanisms, it is difficult to feed various types of rotors, and usually, only one type of rotors can be fed.

Summary of the Invention The purpose of the present invention is to provide an automatic rotor feeding mechanism which can prevent a rotor from getting stuck during its movement and can realize the feeding of various types of rotors.

For this purpose, the present invention employs the following technical solutions. An automatic rotor feeding mechanism is provided, including a collection box, wherein an opening is formed on a front side of the collection box and a rail arranged obliquely is connected to the collection box; the height of the rail gradually decreases from rear to front; the collection box includes a soleplate which has a front side that is lower than a rear side to be obliquely arranged; side plates extending upward are arranged on left and right sides of the soleplate of the collection box; a first driving device and a first partitioning plate are arranged in the collection box; the first partitioning plate is lifted up or down by the first driving device to adjust a distance from a lower edge of the first partitioning plate to an upper edge of the soleplate; and, a rotor is moved to the outside of the collection box through a gap between the first partitioning plate and the soleplate.

In the present invention, a rotor moves on the oblique soleplate and the rail due to its own gravity, without using a manipulator. The failure rate is low and the production cost is low. In the present utility model, due to the arrangement of the collection box, more rotors can be accommodated and uninterruptedly fed. It is more convenient to use and it is more suitable for automatic production devices. A first partitioning plate is provided in the present invention. By controlling the movement height of the first partitioning plate and the time taken for such movement, it is ensured that only one rotor can roll out from the opening of the collection box each time.

Preferably, the side plates include fixed side plates and a moving side plate; the rotor in the collection box is limited between the fixed side plates and the moving side plate; and, the moving side plate is moved left and right in the collection box and fixed to the collection box via a fastener. The rotor is horizontally placed between the fixed side plates and the moving side plate.

The distance between the fixed side plates and the moving side plate is controlled by adjusting the position of the moving side plate in the left-right direction, so that the rotor is prevented from tilting and getting stuck when it rolls down. The distance between the moving side plate and the fixed side plates may be slightly greater than the length of the rotor, so that the rotor is prevented from tilting when rolling, and the rotor is prevented from deviating from the rail. The moving side plate can move left and right, so that the device of the present invention can be used for feeding different types of rotors having different lengths.

Detailed Description of the Invention The present invention will be further described below by specific embodiments with reference to the accompanying drawings.

As shown in Figs. 1-4, the present invention provides an automatic rotor feeding mechanism, including a collection box. An opening is formed on a front side of the collection box and a rail 200 arranged obliquely is connected to the collection box. The height of the rail 200 gradually decreases from rear to front.

The collection box includes a soleplate 1 which has a front side that is lower than a rear side to be obliquely arranged. Side plates extending upward are arranged on left and right sides of the soleplate 1. A first driving device 2 and a first partitioning plate 21 are arranged in the collection box. The first partitioning plate 21 is lifted up or down by the first driving device 2 to adjust a distance from a lower edge of the first partitioning plate 21 to an upper edge of the soleplate 1. A rotor 300 is moved to the outside of the collection box through a gap between the first partitioning plate 21 and the soleplate 1.

The side plates include two fixed side plates 31 and a moving side plate 32 located between the two fixed side plates. The rotor in the collection box is limited between one of the fixed side plates 31 and the moving side plate 32.

The moving side plate 32 is moved left and right in the collection box and fixed to the collection box via a fastener.

A positioning plate 4 is arranged on the front side of the soleplate 1. A number of second elongated grooves 41 which are arranged up and down at intervals and run through the positioning plate 4 from front and rear sides are formed on the positioning plate 4. The second elongated grooves 41 are arranged in the left-right direction. The fastener includes second bolts 42 fitted in the second elongated grooves 41. First fixation holes for fitting the second bolts 42 are formed on a front end face of the moving side plate 32.

A guide rod 5 arranged in the left-right direction is fixed on the fixed side plates. A third elongated groove 51, which runs through the guide rod 5 from upper and lower sides and is arranged in the left-right direction, is formed on the guide rod 5. A second fixation hole, which runs through the moving side plate 32 upward and is communicated with the third elongated groove 51, is formed on the moving side plate 32. The fastener includes third bolts fitted in the second fixation hole and the third elongated groove 51. Both an outer edge of the cross-section of the guide rod 5 and an inner edge of the cross-section of the guide groove are square.

A guide block 6 extending to an upper side of the positioning plate 4 is fixed on the moving side plate 32. A fourth elongated groove 61, which runs through the guide block 6 from upper and lower sides and is arranged in the left-right direction, is formed on the guide block 6. An upper end face of the positioning plate 4 is recessed downward to form a number of third fixation holes 43 arranged left and right at intervals. The fastener includes third bolts fitted in the fourth elongated groove 61 and the third fixation holes 43.

An opening facing downward is formed at the front end of the collection box, and the opening is located between the lower end of the soleplate and the lower end of the positioning plate 4. A bearing platform 7 is arranged on a lower side of the opening of the collection box, and the bearing platform 7 is always located on the lower side of the opening of the collection box. The rail 200 is connected to the bearing platform 7. Bearing platform limiting plates 71 are arranged on left and right sides of the bearing platform 7. A rear stopper 72 is arranged on a rear side of the bearing platform 7. A front end face of the rear stopper 72 is a slope having a front side lower than a rear side, and is located directly below the opening of the collection box. The bearing platform 7 is equipped with a lifting mechanism 73 for adjusting the height of the bearing platform. The position of an upper edge of the rail 200 is higher than the position of an upper end face of the bearing platform 7. The moving side plate 32 is fixed to one of the bearing platform limiting plates 71 to realize linkage.

The lifting mechanism is any manually-operated or electrical mechanism capable of changing the height of the bearing platform.

A spacing and blocking mechanism is arranged on the rail 200. The spacing and blocking mechanism includes a second partitioning plate 81 and a third partitioning plate 82. The third partitioning plate 82 is located in front of the second partitioning plate 81. Each of the second partitioning plate 81 and the third partitioning plate 82 is equipped with a second driving device 83. Both the second partitioning plate 81 and the third partitioning plate 82 are used for preventing the continuous movement of the rotor 300 on the rail 200. The thickness of each of the first partitioning plate 21, the second partitioning plate 81 and the third partitioning plate 82 gradually decreases from the top down.

The rail 200 includes a first rail 91 and a second rail 92 for supporting two ends of a rotor shaft of the rotor 300. When the rotor 300 rolls on the rail 200, a core of the rotor 300 is limited between the first rail 91 and the second rail 92.

The first rail 91 and the second rail 92 are both fixed on a rail support plate 93.

A first elongated groove 94 arranged in a left-right direction is formed on the rail support plate 93, and a positioning member is fitted in the first elongated groove 94. A positioning hole 95 for fitting the positioning member is formed on the second rail 92. The positioning member includes a first bolt and a first nut.

The second rail 92 is moved left and right along the first elongated groove 95 and fixed on the rail support plate 93 via the positioning member.

When in use of the present invention, a number of rotors are put in the collection box. By moving the moving side plate, there are only gaps between two axial ends of the rotor shaft and the side plates. The first partitioning plate is controlled to move up or down by the first driving device, so that only one rotor rolls forward due to its gravity each time. Since there is a certain height difference between the upper end face of the bearing platform and the upper end face of the rear end of the rail, a number of rotors will be collected on the bearing platform so that the front-most rotor on the bearing platform comes into contact with the rear end of the guide rail. When a new rotor falls on the bearing platform, this rotor drops on the rearmost rotor on the bearing platform, so that the front-most rotor is pushed to move forward and upward so as to move to the rail.

When the third partitioning plate is moved up by two second driving devices, the second partitioning plate can block the movement of the rotor on the rear side. Subsequently, the third partitioning plate is moved down and the second partitioning plate is moved up, so there will be a rotor between the second partitioning plate and the third partitioning plate again. Thus, the sequential feeding of rotors is realized.

When it is necessary to feed other types of rotors, the moving side plate and the second rail are moved left and right.
