[0049] The storage box 43 body 4 is equipped with a transmission track and a storage track, which are used for transmitting and storing circuit boards respectively, at this time, the storage box 43 body 4 includes a fixed side plate 41 fixed on the upper side of the workbench 1, the side edge of the fixed side plate 41 is equipped with a vertical rod 42, the side edge of the vertical rod 42 is equipped with a storage box 43 moving up and down, the side edge of the fixed side plate 41 is equipped with an adjusting structure 421 for controlling the storage box 43 to move up and down along the vertical rod 42. The adjusting structure 421 is a motor lead screw structure, in this way, under the action of the adjusting structure 421, the storage box 43 can move up and down along the vertical rod 42.

[0050] The storage box 43 is used for storing and transferring circuit boards, and comprises a bottom plate 431 connected with the vertical rod 42 through a linear bearing, a first vertical plate 432 and a second vertical plate 433 arranged on the upper side of the bottom plate 431, a plurality of conveying tracks 434 arranged in an up-down manner on the opposite inner sides of the first vertical plate 432 and the second vertical plate 433, a rotating shaft 44 rotatably connected with the first vertical plate 432 or the second vertical plate 433, a storage conveying belt 441 arranged on the outer side of the rotating shaft 44, and a driving structure 45 arranged on the side edge of the fixed side plate 41 and used for driving the rotating shaft 44 to rotate. When the rotating shaft 44 is in conduction with the driving structure 45, the driving structure 45 drives the rotating shaft 44 and the storage conveying belt 441 to rotate. When the rotating shaft 44 is separated from the driving structure 45, the rotating shaft 44 and the storage conveying belt 441 stop rotating. The bottom plate 431 is connected with the vertical rod 42 through a linear bearing, and is fixed with a moving pair of a motor screw structure. Thus, under the action of the adjusting structure 421, the bottom plate 431 can move up and down.

[0051] The first vertical plate 432 and the second vertical plate 433 are arranged on the upper side of the bottom plate 431, and a plurality of conveying tracks 434 arranged in up-down direction are arranged on the opposite inner sides, and the conveying tracks 434 are arranged in parallel in up-down direction, at this time, the conveying track 434 comprises a rotating shaft 44, at this time, the rotating shaft 44 is provided with a storage conveying belt 441 through a rotating wheel, when the rotating shaft 44 rotates, the rotating wheel rotates synchronously, so as to make the storage conveying belt 441 rotate, and a driving structure 45 for driving the rotating shaft 44 is arranged on the side of the fixed side plate 41, at this time, the rotating shafts 44 arranged in up-down direction are not associated, that is, when one of the rotating shafts 44 rotates, if the other rotating shafts 44 are not connected with the driving structure 45, the other rotating shafts 44 are static, and the corresponding storage conveying belts 441 are also static, in this way, in the initial state, one of the rotating shafts 44 and the storage conveying belt 441 correspond to the feeding track 2, when the circuit board meets the requirements through the detection structure 3, the rotating shaft 44 and the storage conveying belt 441 at the same height position rotate under the action of the driving structure 45, so that the circuit board at this time can be directly moved from the upper side of the storage conveying belt 441 to the position of the discharging track 5, that is, the storage conveying belt 441 at this time is a conveying track, if the detection structure detects that the circuit board does not meet the requirements, the circuit board needs to be stored in the storage box 43 body 4, at this time, after the circuit board moves to the storage conveying belt 441 at the same height position, the driving structure 45 stops, so that the storage conveying belt 441 stops rotating, and the circuit board stays on the upper side of the storage conveying belt 441, at this time, the storage conveying belt 441 is a storage track, under the action of the adjusting structure 421, the storage box 43 moves up and down, and then the storage conveying belt 441 at the upper side or the lower side position moves to the position with the same height as the feeding track 2, for the transmission or storage of the next circuit board, in this way, the unqualified circuit board can be stored in the position of the storage box 43 body 4.

[0052] At the same time, at this time, if the circuit board on the storage conveying belt 441 needs to be moved, the storage conveying belts 441 on the sides of the first vertical plate 432 and the second vertical plate 433 need to rotate synchronously, therefore, the rotating shafts 44 are arranged on the sides of the first vertical plate 432 and the second vertical plate 433, at this time, the rotating shafts 44 are connected with the first vertical plate 432 and the second vertical plate 433 through bearings, and relative rotation between the first vertical plate 432 and the second vertical plate 433 can occur.

[0053] At this time, the rotation of the rotating shaft 44 needs to be controlled by the driving structure 45, therefore, in the embodiment, the driving structure 45 comprises a driving motor 450, the shaft of the driving motor 450 is connected with a rotating rod 451, the rotating rod 451 is provided with a rotating groove 4511, the rotating shaft 44 is provided with a clamping portion 442 clamped in the rotating groove 4511, when the clamping portion 442 of the rotating shaft 44 is clamped in the rotating groove 4511 of the rotating rod 451, the rotating shaft 44 rotates synchronously with the rotating rod 451. When the rotating groove 4511 of the rotating rod 451 is clamped with the clamping portion 442 of the rotating shaft 44, the rotation of the rotating rod 451 can be transmitted to the rotating shaft 44, when the rotating rod 451 is separated from the rotating shaft 44, the rotating shaft 44 has no rotating power, therefore, the rotating shaft 44 and the corresponding storage conveying belt 441 will not rotate.

[0054] Specifically, in order to realize that the rotating groove 4511 and the clamping portion 442 can transmit rotation when clamped and can be separated, in the embodiment, the rotating groove 4511 is a T-shaped groove, comprising a horizontal groove and a vertical groove, the vertical groove extends to the end face of the rotating rod 451 and communicates with the outside, the clamping portion 442 is T-shaped matched with the rotating groove 4511, the clamping portion 442 is provided with two symmetrical grooves, the outside of the groove forms a horizontal portion matched with the horizontal groove and a vertical portion matched with the vertical groove. When the vertical groove of the rotating groove 4511 remains in a vertical state, the clamping portion 442 can be moved into the vertical groove of the rotating groove 4511 during the up and down movement, thereby connecting the rotating rod 451 and the rotating shaft 44 together, when it is needed to separate the two, only need to keep the vertical groove of the rotating groove 4511 in a vertical state, so that the clamping portion 442 of the rotating shaft 44 moves up and down, the rotating rod 451 and the rotating shaft 44 can be separated, thereby realizing the connection and separation of the rotating shaft 44 and the driving structure 45.

[0055] Therefore, when the different rotating shafts 44 are switched to be connected with the rotating rod 451, the grooves of the clamping portions 442 of the rotating shafts 44 need to be kept in the two side positions during the up and down movement of the rotating shafts 44. Therefore, in the embodiment, the side edges of the fixed side plate 41 are provided with guide rods 46, the guide rods 46 are provided with T-shaped guide grooves 461, the clamping portions 442 of the rotating shafts 44 are clamped in the T-shaped guide grooves 461, the guide rods 46 are provided with communication holes 462, the rotating rod 451 passes through the communication holes 462 to the T-shaped guide grooves 461, and the rotating groove 4511 of the rotating rod 451 corresponds to the T-shaped guide groove in the up and down direction. All the rotating shafts 44 are clamped in the T-shaped guide grooves 461 in the groove position, at this time, the groove of the rotating shaft 44 is clamped with the outside protrusion of the T-shaped guide groove, so that during the up and down movement of the storage box 43, the grooves of all the rotating shafts 44 are in the vertical direction, at the same time, the rotating rod 451 is inserted into the T-shaped guide groove 461 at the position of the communication hole 462, at this time, the vertical groove of the rotating rod 451 keeps vertical, so that when the rotating shaft 44 moves to the side edge of the rotating rod 451 during the up and down movement of the rotating shaft 44 in the T-shaped guide groove 461, the clamping portion 442 of the rotating shaft 44 can be directly moved into the T-shaped groove of the rotating rod 451, so as to realize the connection between the rotating shaft 44 and the rotating rod 451, so that when the rotating rod 451 rotates, the rotating shaft 44 will rotate synchronously.

[0056] During the rotation of the rotating rod 451 and when the rotating rod 451 stops rotating, the rotating angle position of the rotating rod 451 needs to be detected, and it is necessary to ensure that the vertical groove of the rotating rod 451 keeps vertical position during the switching of the rotating shaft 44 and the rotating rod 451. Therefore, in the embodiment, the outside of the rotating rod 451 is provided with a detection sensor 47 for detecting the rotating angle position of the rotating rod 451. Thus, the angle position of the rotating rod 451 is detected, and at this time, the motor for driving the rotation of the rotating rod 451 is a stepping motor, which can further control the rotating angle position of the rotating rod 451.

[0057] At this time, the side edge positions of the first vertical plate 432 and the second vertical plate 433 are provided with rotating shafts 44, so that corresponding guide rods 46 and corresponding driving structures 45 are provided at the outside positions. If the first vertical plate 432 and / or the second vertical plate 433 are fixed, the guide rods 46 and the corresponding driving structures 45 can be directly fixed at the side edge positions. If the first vertical plate 432 and / or the second vertical plate 433 need to be moved during use to adjust the distance between them, the corresponding guide rods 46 and driving structures 45 need to be fixed with the first vertical plate 432 and / or the second vertical plate 433, so that the positions between the guide rods 46, the driving structures 45 and the corresponding rotating shafts 44 remain unchanged, thereby ensuring that the rotating shafts 44 can be driven to rotate.

[0058] For the feeding track 2 and the discharging track 5, which are used for conveying the circuit board, in the embodiment, the feeding track 2 and the discharging track 5 each include a first fixed plate 21 fixed on the upper side of the workbench 1 and a second moving plate 22 arranged on the upper side of the workbench 1 through a guide rail sliding block structure, the inner side of the first fixed plate 21 and the second moving plate 22 is provided with an in-out rotating shaft 23, the outer side of the in-out rotating shaft 23 is provided with an in-out conveying belt 24, and the side of the first fixed plate 21 or the second moving plate 22 is provided with an in-out motor 25 used for driving the in-out rotating shaft 23 to rotate.
