Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention will be further described below in conjunction with the embodiments. Example

[0032] See also Figure 1-Figure 9 The present invention provides a technical solution for a circuit board feeding device for producing a Bluetooth headset: Figure 1 and Figure 2 As shown, the device includes a fixture plate 2 for receiving the circuit boards that fall in sequence, the fixture plate 2 is mounted on the surface of the transmission mechanism 1, the transmission mechanism 1 transmits the circuit boards by intermittent transmission, a discharge box 3 is mounted above the transmission mechanism 1, a storage box 31 for temporarily storing the circuit boards is fixedly mounted in the discharge box 3, a through slot is opened in the middle of the storage box 31, and the through slot is located at the upper position of the discharge box 3, so that the staff can place the circuit boards into the storage box 31 at any time, and reloading can be realized without stopping the machine, such as Figure 6 As shown, the lower part of the material storage box 31 is located inside the material discharge box 3, and a discharge slot 311 is provided at the lower position of the material storage box 31. The height dimension of the discharge slot 311 is larger than the height dimension of a single circuit board. The circuit boards in the material storage box 31 fall into the discharge slot 311 under the action of gravity, and only one circuit board can fall completely. In the initial state, a push plate 32 is slidably connected to the side of the discharge slot 311, and the bottom end of the push plate 32 is in contact with the bottom end of the discharge slot 311. The height dimension of the push plate 32 is smaller than the size of a single circuit board, and the length dimension of the push plate 32 is larger than the size of the discharge slot 311. When the push plate 32 rotates at a small angle, the end of the push plate 32 away from the rotation center can rotate from one side of the discharge slot 311 to the other side of the discharge slot 311, and the other end of the push plate 32 is fixedly connected to the output end of the transmission box 33.

[0033] refer to Fig. 9, a movable part is arranged inside the transmission box 33 to drive the push plate 32 to rotate back and forth, and the movable part includes a bevel gear 1 331 fixedly connected to the bottom end of the push plate 32, the bottom end of the bevel gear 1 331 is meshedly connected with a fan gear 332, the bottom end of the fan gear 332 is meshedly connected with a bevel gear 2 333, the bevel gear 2 333 and the bevel gear 1 331 are symmetrically arranged with the fan gear 332 as the center, and the middle part of the bevel gear 2 333 and the bevel gear 1 331 is fixedly connected by a round rod, the other end of the fan gear 332 is connected to the motor in the transmission box 33, and the area ratio of the gear surface and the smooth surface of the outer surface of the fan gear 332 is approximately 1 / 3.

[0034] The gear 332 is then rotated 270 degrees to move the gear 332 to the other side of the discharging trough 311, and the gear 332 is then engaged with the bevel gear 331, and the bevel gear 331 is engaged with the push plate 32 to move. The second bevel gear 333 is meshed and connected, and the rotation of the sector gear 332 drives the bevel gear 2 333 to rotate in the opposite direction. The bevel gear 2 333 drives the bevel gear 1 331 to rotate in the opposite direction through the round rod. The bevel gear 1 331 drives the push plate 32 to rotate from one side of the discharge trough 311 to its original position, and at the same time squeezes the new circuit board falling from the inside of the discharge trough 311, thereby pushing the other circuit board out of the discharge trough 311. Finally, the sector gear 332 rotates 360 degrees, and the gear surface of the sector gear 332 does not mesh with the bevel gear 1 331 and the bevel gear 2 333. At this time, the bevel gear 1 331 drives the push plate 32 to rotate to the initial position of the discharge trough 311. In the process of one rotation of the sector gear 332, the push plate 32 completes one round trip in the discharge trough 311, and completes the unloading operation of the two circuit boards in this process, thereby realizing uninterrupted unloading operation and improving the unloading efficiency.

[0035] refer to Figure 2 and Figure 3, both ends of the discharge trough 311 are provided with fixing frames 35, and the top height of the fixing frames 35 is slightly lower than the height of the lower surface of the discharge trough 311. After the circuit board is completely placed on the upper surface of the fixing frames 35, the end of the push plate 32 moved to the extreme angle and located inside the discharge trough 311 can be located in the gap between the fixing frames 35 and the discharge trough 311, so as to prevent the push plate 32 from blocking the falling circuit board and facilitate the push plate 32 to push the circuit board when it rotates in the opposite direction. The fixing frame 35 includes a slider 3 slidably connected to the positioning member 36 provided on the inner wall of the discharge box 3. 59. The slider 359 is fixedly connected to a horizontal plate 351 on the outside, and the horizontal plate 351 is slidably connected to a vertical plate 353 in the vertical direction. The cavity surrounded by the two horizontal plates 351 and the vertical plate 353 is used to place the circuit board. A rubber strip 352 is fixedly connected to the side of the horizontal plate 351 close to the circuit board. The rubber strip 352 is provided in two different sizes, the small-sized rubber strip 352 is provided at the top, and the large-sized rubber strip 352 is provided at the bottom, so as to facilitate the embedding of the circuit board therein. The two rubber strips 352 clamp and limit the side of the circuit board.

[0036] refer to Figure 6 and Figure 7 A pressure member 34 is arranged above the fixed frame 35. In the initial state, the bottom end of the pressure member 34 is higher than the top end of the discharge trough 311. The pressure member 34 includes a pressure plate 1 341 that is in contact with the inner wall of the discharge box 3. A plurality of spring members 342 are evenly arranged at the bottom end of the pressure plate 1 341. The bottom end of the pressure plate 1 341 is elastically connected to the pressure plate 2 343 through the spring member 342. A positioning rod 344 is arranged in the cavity surrounded by the pressure plate 1 341 and the pressure plate 2 343. Fixed blocks are rotatably connected at both ends of the positioning rod 344. The top end of the fixed block is fixedly connected to the bottom end of the pressure plate 1 341. An eccentric wheel 345 is fixedly connected to the outer side of the pressure plate 1 341. A flat gear 346 is fixedly connected to the middle part of the positioning rod 344. The eccentric wheel 345 is centered on the flat gear 346. There are two of them. In the initial state, the upper and lower ends of the eccentric wheel 345 are respectively fitted with the pressure plate 1 341 and the pressure plate 2 343. At this time, the height between the pressure plate 1 341 and the pressure plate 2 343 is the smallest. The bottom end of the flat gear 346 is meshed with the tooth plate 381 of the linkage member. The other end of the tooth plate 381 is fixedly connected with a slide rod 382, ​​and the bottom end of the slide rod 382 is fixedly connected with a frame plate 383. The frame plate 383 and the slide rod 382 are both slidably arranged in the frame groove 314 opened above the discharge chute 311. The other end of the frame plate 383 is hinged with a block 384. The block 384 passes through the slot hole 313. The slot hole 313 is opened on the inner wall of the arc-shaped slot 312 at the bottom of the discharge chute 311. The inner wall of the arc-shaped slot 312 is slidably connected with a round block fixedly connected to the bottom end of the push plate 32.

[0037] When the push plate 32 completely pushes the circuit board inside the discharge slot 311 to above the fixing brackets 35 at both ends of the discharge slot 311, Figure 7As shown, the round block at the bottom of the push plate 32 contacts the block 384, but at this time the push plate 32 continues to rotate under the action of the movable part, and the round plate pushes the block 384 to move in the slot 313 along the inner wall of the arc groove 312, and the block 384 drives the frame plate 383 to move in the frame groove 314, and the slide bar 382 drives the tooth plate 381 to move. In the initial state, the tooth plate 381 is located below the flat gear 346, and the two are not meshed. The movement of the tooth plate 381 can mesh with the flat gear 346, and the rotation of the flat gear 346 drives the positioning rod 344 to rotate, and the rotation of the positioning rod 344 drives the eccentric wheel 345 to rotate, and the rotation of the eccentric wheel 345 is driven by the pressure plate 346. 41 and the second pressure plate 343 are rotated from a parallel state to a perpendicular state with the second pressure plate 343 and the first pressure plate 341, thereby increasing the gap between the second pressure plate 343 and the first pressure plate 341, and the circuit board completely placed on the fixing frame 35 is squeezed by moving the second pressure plate 343 downward, so that the circuit board is engaged in the gap between the two rubber strips 352, thereby ensuring the stability of the circuit board during the unloading process and avoiding its deviation. When the eccentric wheel 345 rotates to the maximum value, the squeezing of the second pressure plate 343 reaches the maximum value. At this time, the second pressure plate 343 can also squeeze the fixing frame 35 that fixes the circuit board, so that the fixing frame 35 moves downward a certain distance as a whole.

[0038] refer to Figure 2 , Figure 3 and Figure 5 The fixing frame 35 also includes a magnetic block 354 which is slidably arranged on the side of the longitudinal plate 353 away from the circuit board. The side of the magnetic block 354 close to the circuit board is movably connected to the inner support member arranged on the inner side of the groove of the longitudinal plate 353. The magnetic block 354 is magnetically connected to the electromagnetic coil 21 at both ends of the clamp plate 2. After the fixing frame 35 is squeezed by the pressing plate 343 as a whole and then moves downward, the magnetic block 354 enters the magnetic induction area of ​​the electromagnetic coil 21, and the two attract each other, and the bottom end of the fixing frame 35 quickly fits with the upper surface of the clamp plate 2.

[0039] refer to Figure 3 and Figure 4 The inner support member includes a vertical rod 356 fixed inside the longitudinal plate 353, and a connecting plate 355 is slidably connected to the outer side of the vertical rod 356. There are two connecting plates 355, and a reset spring is installed between the two connecting plates 355. Both ends of the connecting plate 355 are rotatably connected to a connecting rod 357, and the other end of the connecting rod 357 is rotatably connected to another connecting plate 355. The middle part of the connecting rod 357 is rotatably connected to a push block 358 away from the vertical rod 356. In the initial state, when the magnetic field of the electromagnetic coil 21 cannot affect the magnetic block 354, the upper connecting plate 355 is fitted with the top of the inner wall of the groove under the action of the reset spring. The height dimension of the connecting rod 357 is the largest and the width dimension is the smallest. At this time, the rubber strip 352 and the circuit board are tightly fitted.

[0040] refer to Figure 2 and Figure 8The positioning member 36 includes a slide plate 361 fixed to the inner wall of the discharge box 3, a slide plate 361 is provided with a slide groove inside, a slide plate 362 is arranged below the slide plate 361, and a slide groove with the same shape and size as the slide groove of the slide plate 361 is provided inside the slide plate 362. Under the initial condition, the slide groove of the slide plate 361 and the slide groove of the slide plate 362 can form a complete channel. The compression spring elastically connected to the end of the slider 359 is connected to the top of the inner wall of the slide plate 361, and the outer side of the slide plate 362 is fitted with the spring piece 363 embedded in the inner side of the rectangular groove 364, and the slide plate 362 can be slidably connected inside the rectangular groove 364.

[0041] When the eccentric wheel 345 of the fixing frame 35 squeezes the pressure plate 2 343 to the limit, the slider 359 slides in the slide groove inside the slide plate 1 361 until the slider 359 completely slides to the inside of the slide plate 2 362, and then enters the magnetic induction area of ​​the electromagnetic coil 21. The electromagnetic coil 21 and the magnetic block 354 attract each other, and the magnetic block 354 drives the connecting plate 355 to move downward along the groove. When the upper surface of the clamp plate 2 is rapidly attached to the lower surfaces of the horizontal plate 351 and the longitudinal plate 353, the magnetic block 354 drives the connecting plate 355 to move to the bottom of the groove. At this time, the connecting plate 355 moves downward to drive the connecting rod 357 to deform, and the connecting rod 357 is the largest in height and the smallest in width. The state is deformed into a state with the smallest height dimension and the largest width dimension, thereby pushing the push block 358 to the side away from the vertical rod 356. The movement of the push block 358 drives the horizontal plate 351 to move. At this time, the horizontal plate 351 squeezes the slider 359, and the slider 359 drives the second slide plate 362 to move inside the rectangular groove 364. The second slide plate 362 squeezes the spring piece 363, and the distance between the two horizontal plates 351 increases. When the distance between the two is greater than the size of the circuit board, the circuit board is separated from the restriction of the rubber strip 352. The circuit board is limited by the two longitudinal plates 353 to ensure that the circuit board can fall accurately on the fixture plate 2, thereby avoiding position displacement during the circuit board falling off.

[0042] After the circuit board is placed in the fixture plate 2, the transmission mechanism 1 starts to transmit the fixture plate 2. At this time, the current direction of the electromagnetic coil 21 is opposite, the magnetic pole direction of the electromagnetic coil 21 changes, and the magnetic force between the electromagnetic coil 21 and the magnetic block 354 repel each other. The electromagnetic coil 21 pushes the magnetic block 354 to move upward, and the movable part is restored to the initial position. The horizontal plate 351 and the vertical plate 353 are restored to a position where they fit together. In this process, the horizontal plate 351 and the vertical plate 353 are also moved upward synchronously until the slider 359 moves from the slide groove of the slide plate 2 362 to the slide groove of the slide plate 1 361. At this time, the slider 35 9 no longer squeezes the slide plate 362, the elastic deformation of the spring piece 363 is restored, and the slide plate 362 is pushed to the initial position. The slide grooves of the slide plates 1 361 and the slide plate 2 362 form a complete channel again. Because the gravity of the circuit board's detachment slider 359 is reduced, the pressure plate 2 343 no longer squeezes it, and the compression spring of the slider 359 is elastically deformed and restored. The slider 359 moves along the slide groove of the slide plate 1 361, driving the horizontal plate 351, the rubber strip 352 and the longitudinal plate 353 to move to the initial position. The slide groove ensures the stability of the movement of the slider 359, which is convenient for the next unloading of the circuit board.
