[0002] SMT is the surface assembly technology (surface mount technology), the full name of which is Surface Mount Technology. It is currently the most popular technology and process in the electronic assembly industry. SMT circuit boards need to be stored after production is completed or during transportation. An existing SMT circuit board storage rack has a card slot at one end of the storage rack that can slide longitudinally relative to the storage rack, and the card slot at the bottom is fixed relative to the storage rack. After the first circuit board is inserted to determine the height and fix the card slot, circuit boards of the same height can continue to be inserted into the storage rack for storage. However, this method has certain defects. After the card slot is fixed, if you want to continue inserting the circuit board, you need to align the circuit board with the card slots at the upper and lower ends at the same time before you can slide it into the card slot. The operation is relatively complicated and will take a certain amount of time. For this reason, we propose an SMT circuit board storage device. Utility Model Content

[0034] See also Figure 1-11 The utility model provides a technical solution: an SMT circuit board storage device, including a frame 1 of a storage rack, the frame 1 includes a fixed lower card slot 2, and also includes:

[0035] A vertical card slot 3, which is rotatably arranged on the frame 1 and fits with the lower card slot 2. A slot for sliding a circuit board is provided on the vertical card slot 3, and the slot on the vertical card slot 3 corresponds to the slot on the lower card slot 2 one by one;

[0036] An upper card slot 4, which is arranged on the frame 1;

[0037] The toothed disc 5 is fixedly connected to the vertical slot 3;

[0038] The upper slot 4 is rotatably connected with a movable block 41 via a rotating shaft. The movable block 41 slides on the frame 1 via a limiting shaft. A shaft 42 is fixedly installed on the vertical slot 3 , and the shaft 42 is fixedly connected with the gear disc 5 .

[0039] The deflection assembly 6 is arranged on the frame 1, the deflection assembly 6 is in contact with the upper card slot 4, the toothed disc 5 is connected to the deflection assembly 6, the deflection frame 1 is deflected to make the upper card slot 4 perpendicular to the lower card slot 2, and the toothed disc 5 is driven to rotate by the deflection assembly 6, so that the vertical card slot 3 is deflected to a state perpendicular to the lower card slot 2, and then the circuit board is slid along the groove on the vertical card slot 3 to be inserted into the lower card slot 2. Specifically, the deflection assembly 6 includes a rack 61 slidably arranged on the frame 1, the rack 61 is meshed with the toothed disc 5, and one end of the rack 61 is fixedly connected to a rod 6 2. Rod 1 62 is located in the frame 1 and slides. A corresponding groove is provided on the frame 1 for sliding. A fixed block 63 is slidably provided at the other end of the rod 1 62. One end of the fixed block 63 is triangular in design. The fixed block 63 is located in the frame 1 and slides. A corresponding groove is provided on the frame 1 for sliding. An L-shaped plate 64 is fixedly connected to the fixed block 63. One end of the L-shaped plate 64 contacts the upper slot 4. A spring 65 is provided on the fixed block 63. The two ends of the spring 65 are respectively fixedly connected to the fixed block 63 and the rod 1 62. A pull rope 74 is also connected to the fixed block 63.

[0040] A tension spring 66 is also provided on the rod 1 62, and the two ends of the tension spring 66 are respectively fixedly connected to the rod 1 62 and the frame 1, so as to drive the toothed disc 5 to rotate through the elastic force of the tension spring 66;

[0041] At the beginning, the upper card slot 4 and the vertical card slot 3 are parallel to the lower card slot 2. The upper card slot 4 can slide on the frame 1 through the movable block 41, and the vertical card slot 3 is close to the lower card slot 2, while the lower card slot 2 is fixed. When the circuit board needs to be inserted, the pull rope 74 is first pulled to drive the fixed block 63 in the slot 1 71 to slide, so that the shaft 2 73 and the upper card slot 4 are unlocked and disengaged, and then the handle 10 is pulled to drive the upper card slot 4 to deflect to be perpendicular to the lower card slot 2. In this process, the upper card slot 4 first contacts the fixed block 63 on the frame 1 and pushes the fixed block 63 to slide, and then under the action of the spring 65, the fixed block 63 slides out and positions the upper card slot 4, and then the upper card slot 4 pushes the L-shaped plate 6 4, driving the L-shaped plate 64 to slide, and then driving the fixed block 63 to slide, so that the fixed block 63 is separated from the frame 1, and then the rod 1 62 is separated from the frame 1, and then under the elastic force of the tension spring 66 on the rod 1 62, the rod 1 62 slides and automatically returns to its position, and then drives the rack 61 to slide, and then drives the gear plate 5 to rotate, thereby driving the shaft 1 42 to rotate, and then drives the vertical card slot 3 to deflect and tilt, so that the vertical card slot 3 deflects to be perpendicular to the lower card slot 2. At this time, the upper card slot 4 and the vertical card slot 3 are located in the same plane, and then the circuit board is slid along the grooves on the two card slots, and the circuit board slides along the groove to the upper groove of the lower card slot 2, so that the circuit board can be inserted into the storage rack by aligning the card slot only once;

[0042] When it is desired to reset, the pull rope 74 is pulled to drive the fixed block 63 on the frame 1 to slide, thereby unlocking the upper slot 4. The handle 10 is then pulled to deflect the upper slot 4, so that the slot 1 71 on the block 1 7 is aligned with the shaft 2 73, and the block 63 is then pushed. Under the action of the spring 65, the fixed block 63 pops out into the slot corresponding to the shaft 2 73, thereby locking the upper slot 4. At this time, the upper slot 4 is parallel to the lower slot 2, and the handle 10 is then pulled to slide the upper slot 4. At this time, the circuit board is locked by the lower slot 2 and the vertical slot. The slot 3 is limited at the same time, so it cannot move. The upper slot 4 can easily slide the slot into the circuit board to complete the limitation of the circuit board, and then pull the pull rope 74 to drive the fixed block 63 on the rod 62 to slide, and then drive the rod 62 to slide, thereby driving the rack 61 to slide, and then drive the gear plate 5 to rotate, thereby driving the vertical slot 3 to deflect in the opposite direction and return to the original position, that is, the position that fits with the lower slot 2. At the same time, the fixed block 63 on the rod 62 slides into the corresponding slot on the frame 1 to complete the fixation of the rack 61.

[0043] A block 7 is fixedly connected to the upper slot 4, and a U-shaped slot 71 is provided on the block 7. A rod 72 is fixedly provided on the movable block 41. The rod 72 slides on the frame 1, and a corresponding slot is provided on the frame 1. A shaft 73 is provided on the other end of the rod 72, and the shaft 73 is located in the slot 71. A fixed block 63 is also slidably provided on the slot 71, and a spring 65 is also provided on the fixed block 63. A pull rope 74 is connected to the fixed block 63, and the fixed block 63 slides in the shaft 73, and a corresponding slot is provided on the shaft 73 for positioning the upper slot 4. Two rods 72 are provided, which are respectively located on both sides of the frame 1. When the upper slot 4 slides longitudinally, the rod 72 is driven to slide accordingly, so that the upper slot 4 can be further limited.

[0044] A bolt 8 is connected to the upper slot 4 by a threaded rotation, and one end of the bolt 8 contacts the inner wall of the frame 1. The frame 1 is also provided with a fixing block 63, and the fixing block 63 is also provided with a spring 65 and a pull rope 74 to limit the vertical upper slot 4. When the upper slot 4 parallel to the lower slot 2 slides to the required position, the bolt 8 is rotated so that its front end contacts and abuts against the frame 1, thereby completing the limiting fixation of the upper slot 4.

[0045] One end of the lower card slot 2 is a bevel with an angle of 45 degrees. One end of the vertical card slot 3 is also a bevel. The two bevels are in contact with each other. A handle 10 is installed on the upper card slot 4. The advantage of the bevel is that the vertical card slot 3 and the lower card slot 2 fit better, which facilitates the sliding of the circuit board.

[0048] A torsion spring 9 is provided on the movable block 41, and the two ends of the torsion spring 9 are fixedly connected to the movable block 41 and the upper slot 4 respectively, so as to drive the upper slot 4 to automatically reset through the elastic force of the torsion spring 9. The advantage of the torsion spring 9 is that it assists the upper slot 4 to return to its original position, which can save more effort.
