The button-shaped micro vibration motor mainly comprises a lower shell, an FPC board, magnetic steel, a rotor, an upper shell and other components. The FPC board is provided with a penetrating part for connecting a circuit, and the front side of the FPC board is welded with an electric brush; an opening for the penetrating part of the FPC board to pass through is arranged on the peripheral side of the lower shell, a supporting part corresponding to the penetrating part of the FPC board is arranged on the outer side of the opening, and a cylinder part for riveting a shaft is arranged in the middle of the front of the lower shell; the upper shell is provided with a convex edge part which forms a closed state for the opening. When assembling the micro vibration motor, the lower housing, the FPC board, and the upper housing need to be positioned so that the opening of the lower housing, the penetrating portion of the FPC board, and the protruding edge portion of the upper housing correspond to each other.

In the prior art, when a micro vibration motor is assembled, the positioning is mostly realized by manually placing components such as a lower shell, an FPC (flexible printed circuit) board and an upper shell on a material tray, and then the components which are positioned are grabbed by a manipulator to be assembled. This has the defects of low automation degree and high labor intensity. Particularly, the thickness of the main body part of the FPC board is very thin, and the electric brush is welded on the main body part of the FPC board, so that the whole shape is extremely irregular; when conveyed through the spiral channel of a conventional vibrating disk, the disks are often stacked one on top of the other and are difficult to align and position.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1 to 7, an embodiment of the present invention provides an FPC board positioning device. The FPC board positioning device comprises a first V-shaped channel 1, a first L-shaped channel 2, a first torsion channel 3 and a first material storage channel 4 which are sequentially communicated. The first V-shaped channel 1 communicates with the spiral channel of the first vibratory pan 5. The width of the transverse part of the first L-shaped channel 2 is matched with the thickness of the main body of the FPC board; it will be appreciated that the width of the transverse portion of the first L-shaped channel 2 is substantially the same as the thickness of the main body of the FPC board to ensure that the FPC board moves downstream against the vertical portion of the first L-shaped channel 2 in a single layer. In order to make the FPC board move along the first L-shaped channel 2 more stably, the vertical portion of the first L-shaped channel 2 may be slightly inclined toward the side away from the FPC board. Further, the first L-shaped channel 2 is located within the range of the first vibratory pan 5, and the FPC boards dropped from the first L-shaped channel 2 fall into the first vibratory pan 5 and are re-conveyed along the spiral passage of the first vibratory pan 5. The first torsion channel 3 limits the FPC board and guides the FPC board to be turned from vertical to right-side-up. First storage channel 4 constitutes spacingly to the brush 42 of FPC board, and the direction of guide FPC board keeps the length direction unanimous with first storage channel 4. A first sealing piece 6 is arranged at the downstream end of the first material storage channel 4, and a first material taking position is formed; it should be understood that the side of the first closure member 6 facing the first magazine 4 constitutes the first filling position. The bottom of the first material taking position is provided with two through holes 7 which are matched with an optical sensor 8; the through hole 7 is positioned in the middle of the first material storage channel 4 in the width direction; the distances from the first sealing piece 6 to the two through holes 7 respectively correspond to the distances from the shaft hole of the FPC board to the two long ends.

The following explains a specific embodiment of the above FPC board positioning device: the FPC board conveyed from the first vibratory pan 5 falls into the first V-shaped tunnel 1 to be turned into an upright state. When the FPC board in the upright state moves to the first L-shaped passage 2, there are two cases; one is a vertical portion to which the brush 42 is welded with the front face facing the first L-shaped passage 2; the other is a vertical portion with the back surface facing the first L-shaped channel 2. The FPC board with the back surface facing the vertical part of the first L-shaped channel 2 can be supported on the first L-shaped channel 2 and move towards the first torsion channel 3; the brushes 42 of the FPC board, which face the vertical portion of the first L-shaped channel 2, abut against the vertical portion of the first L-shaped channel 2, so that the center of gravity of the FPC board is located outside the first L-shaped channel 2, thereby causing the FPC board to fall off the first L-shaped channel 2. Therefore, the orientation positioning of the right side and the back side of the FPC board can be realized. Meanwhile, the width of the transverse part of the first L-shaped channel 2 is matched with the thickness of the main body of the FPC board; it is possible to ensure that the FPC boards are conveyed downstream along the first L-shaped passage 2 in a single layer state. When the FPC board moves to the first storage channel 4 through the first twisting channel 3, the first storage channel 4 can enable the length direction of the FPC board to be consistent with the extending direction of the first storage channel 4 through limiting the electric brushes 42. And finally, when the FPC board moves to the first material taking position of the first material storage channel 4. If the penetrating part 41 of the FPC board is positioned at one end of the FPC board facing the first sealing member 6; the through hole 7 far away from the first sealing piece 6 corresponds to the shaft hole of the FPC board and is in a through state from top to bottom; the through hole 7 near the first sealing member 6 is blocked by the FPC board and is in a closed state. On the contrary, if the penetrating part 41 of the FPC board is located at the end of the FPC board away from the first sealing member 6; the through hole 7 far away from the first sealing member 6 can be shielded by the FPC board and is in a closed state; the through hole 7 near the first sealing member 6 corresponds to the shaft hole of the FPC board and is in a through state from top to bottom. In this way, the states of both the through holes 7 are detected by the optical sensor 8, and the orientation of the FPC board threading part 41 can be specified based on the states of both the through holes 7. When assembling the miniature vibration motor, the FPC board positioning device can realize the automatic positioning of the FPC board, improve the automation degree and reduce the labor intensity.

Further, an FPC board transfer mechanism is arranged above the first material taking position, and the optical sensor 8 and the rotating mechanism are respectively in communication connection with the PLC; FPC board transfer mechanism includes: the vacuum suction device comprises a first vacuum suction nozzle 9, a servo motor 10 for driving the first vacuum suction nozzle 9 to rotate, a first power source 11 for driving the servo motor 10 to vertically move, and a second power source 12 for driving the first power source 11 to transversely move. It should be understood that the first and

second power sources

11 and 12 are one of a cylinder, a hydraulic cylinder, and an electric cylinder. The PLC controller can determine the state of the FPC board at the material taking position through the optical sensor 8 and control the FPC board transfer mechanism to make corresponding actions. The first vacuum nozzle 9 corresponds to the center of the take-off station. When the penetrating part 41 of the FPC board is positioned at one end of the FPC board far away from the first sealing member 6, the vacuum suction nozzle and the FPC board are driven by the servo motor 10 to rotate clockwise by 90 degrees in the horizontal direction when the FPC board is transported by the FPC board transporting mechanism; when the penetrating part 41 of the FPC board is located at one end of the FPC board facing the first sealing member 6, the vacuum suction nozzle and the FPC board are driven by the servo motor 10 to rotate reversely by 90 ° in the horizontal direction when the transfer mechanism transfers the FPC board. Thus, the same orientation of the penetrating parts 41 of the FPC board can be ensured when the FPC board is transferred into the lower shell 39 corresponding to the limiting seat 22.

Further, the upstream end of the vertical part of the first L-shaped channel 2 is butted with the downstream end of one side plate of the first V-shaped channel 1; the top of the side plate of the first V-shaped channel 1 is connected with an inclined plate 13, and the upstream end of the inclined plate 13 is butted with the discharge end of the spiral channel of the first vibrating disk 5; the upstream end of the first V-shaped channel 1 is closed. It should be understood that one side plate of the first V-shaped channel 1 is butted with the vertical part of the first L-shaped channel 2, and the other side plate is located on the same side as the horizontal part of the first L-shaped channel 2; in addition, in order to make the FPC boards attach to the side plate butted with the vertical part of the first L-shaped channel 2, the side plate is slightly inclined towards the side back to the FPC board, and the other side plate is vertical to the horizontal plane.

Further, the first torsion channel 3 includes a long plate 14 that supports the back surface of the FPC board; two long side edges of the long plate 14 are bent inwards to form a first limiting groove 15; the first limiting groove 15 limits two sides and edges of the FPC board; the upstream end of the long plate 14 is vertical and is butted with the downstream end of the vertical part of the first L-shaped channel 2; the long plate 14 is gradually twisted from a vertical state to a support surface facing upward in the process of extending downstream. It should be understood that the first limiting groove 15 will limit the edge of the FPC board and cooperate with the long board 14 to limit the front and back sides of the FPC board.

Further, the first hopper channel 4 includes a floor 16; two long side edges of the bottom plate 16 are respectively matched with the vertical folding edge and the transverse folding edge 17 to form a second limiting groove; the second limiting groove limits two sides and edges of the FPC board; the first material storage channel 4 is used for limiting two electric brushes 42 of the FPC board through two third limiting grooves 18 above the first material storage channel; the width of the upstream section of the transverse folding edge 17 is gradually increased in the process of extending downstream, so that the interval between the two transverse folding edges 17 is gradually reduced, and the electric brush 42 of the FPC board is guided to enter the third limiting groove 18. It should be understood that the second limiting groove will limit the edge of the FPC board and cooperate with the bottom board 16 to limit the front and back sides of the FPC board.

The lower shell 39 is positioned by the lower shell positioning device 20, and the positioned lower shell 39 is placed into the limiting seat 22 of the corresponding station by the lower shell transfer mechanism 23. The shaft is then riveted to the cylindrical portion 44 of the lower case 39. Then, the FPC board transfer mechanism puts the FPC board that has been positioned into the lower housing 39 of the stopper 22 at the corresponding station.

The interval between the discharging channel 30 and the second material storing channel 28 is more than or equal to the maximum thickness of the lower shell 39 and less than twice the maximum thickness of the lower shell 39; it should be understood that it is preferable to make the interval between the discharging channel 30 and the second stock channel 28 slightly larger than the maximum thickness of the lower housing 39. In practical application, an operator may fill the lower housing 39 in the second material storage passage 28, and then start the lower housing positioning device 20; after the pushing member 31 pushes the lower housing 39 at the bottom of the second storing channel 28 to the second material taking position and resets, the lower housing 39 in the second storing channel 28 falls down integrally, so that a space for the lower housing 39 to enter is reserved at the top of the second storing channel 28. This can prevent the lower housing 39 from tipping over in the second magazine 28. One end of the discharging channel 30 is provided with a pushing piece 31 driven by a third power source, and the other end is provided with a second sealing piece 32, so that a second material taking position is formed; it should be understood that the side of the second closure member 32 facing the second magazine 28 constitutes the second fill position. The third power source may be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. When the pushing member 31 pushes the lower shell 39 to the second sealing member 32, the supporting portion 43 of the lower shell 39 completes positioning under the limiting of the pushing member 31 and the second sealing member 32. It will be appreciated that when the lower casing 39 is urged against the second closure member 32 by the pusher 31, the cavity formed between the pusher 31 and the second closure member 32 has the same peripheral profile as the lower casing 39.

The working principle of the lower housing positioning device 20 is as follows: the lower housing 39 fed by the second vibratory pan 29 falls into the second V-shaped channel 25 to be turned into an upright state. When the lower housing 39 in the upright state is moved to the second L-shaped passage 26, there are two cases; one is a vertical portion having a cylindrical portion 44 whose front face faces the second L-shaped passage 26; the other is a vertical portion with the back surface facing the second L-shaped channel 26. The lower housing 39, with its back facing the vertical portion of the second L-shaped channel 26, can rest on the second L-shaped channel 26 and move towards the second torsion channel 27. A lower housing 39 facing the vertical part of the second L-shaped passage 26 from the front, and a cylindrical part 44 thereof abutting against the vertical part of the second L-shaped passage 26; since the length of the cylindrical portion 44 is greater than the thickness of the main body of the lower case 39, the center of gravity of the lower case 39 is located outside the second L-shaped passage 26, resulting in the lower case 39 falling from the second L-shaped passage 26. In this way, the front and back surfaces of the lower case 39 can be positioned in the same direction. The lower housing 39 moves the top of the second magazine 28 through the second twisting passage 27 and is stacked in the second magazine 28 in the up-down direction. The lower shell 39 is pushed to the second sealing member 32 by the pushing member 31, so that the supporting portion 43 of the lower shell 39 can be positioned under the limit of the pushing member 31 and the second sealing member 32. Thus, the lower case 39 is automatically positioned.

Further, the second stock passage 28 includes: a main passage 33 for restricting the outer periphery of the lower housing 39, and a sub passage 34 for restricting the support portion 43 of the lower housing 39; the secondary channel 34 is gradually narrowed from top to bottom to guide the support portion 43 of the lower housing 39 to complete the positioning. It will be appreciated that as the lower housing 39 moves downwardly along the second twisting passage 27, the lower housing 39 will rotate spontaneously as the secondary passage 34 is progressively constricted, automatically adjusting the orientation of its support 43 and thus completing the orientation of the support 43 of the lower housing 39. Thereby making the positioning of the lower housing 39 more stable and reliable.

As shown in fig. 15 to 16, in one embodiment provided by the present application, the upper housing positioning device 21 includes: a sorting plate 46 abutting against the discharge end of the spiral channel of the third vibratory pan 35, a third stock channel 36 connected to the downstream end of the sorting plate 46; the sorting plate 46 is inclined in the width direction; the sorting plate 46 is provided with a first opening groove 37 extending along the length direction of the sorting plate, and the width of the upstream section of the first opening groove 37 is greater than or equal to the length of the convex edge part 45 of the upper shell 40 and is smaller than the radius of the upper shell 40; the third storing channel 36 is provided with a fourth limiting groove 38 which limits the convex edge part 45 of the upper shell 40; the downstream section of the first opening groove 37 gradually narrows as it extends downstream, and guides the flange 45 of the upper case 40 into the fourth limit groove 38.

The working principle of the upper shell positioning device 21 is as follows: the upper casing 40 is conveyed to the sorting plate 46 by the third vibratory pan 35, and also slides in the width direction of the sorting plate 46 when the upper casing 40 moves in the length direction of the sorting plate 46. When the convex edge portion 45 of the upper casing 40 faces downward, the convex edge portion 45 of the upper casing 40 falls into the first open groove 37, and the upper casing 40 hangs from the first open groove 37 of the sorting plate 46 and moves along the sorting plate 46 to the third stock passage 36. When the raised edge 45 of the upper casing 40 is facing upward, the upper casing 40 slides down the sorting plate 46 into the third vibratory pan 35 and is re-conveyed along the spiral path of the third vibratory pan 35. Moving to the upper case 40 of the third magazine 36, the raised edge portion 45 thereof is caught in the fourth catching groove 38. Thereby completing the positioning of the upper case 40.

Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that changes or modifications may be made to these embodiments without departing from the principles and spirit of the invention, and that such changes and modifications are within the scope of the invention.
