[0029] See also Figure 1-5 A circuit board docking station comprises a frame 1, two support plates 2 are fixedly arranged on the upper end of the frame 1, two limit rods 3 are fixedly connected between the two support plates 2, two adjustment plates 4 are slidably connected to the two limit rods 3, a first motor 5 is fixedly arranged in the frame 1, a driving end of the first motor 5 passes through the frame 1 and is fixedly connected to a rotating gear 6, the rotating gear 6 is meshedly connected to two racks 7, the two racks 7 are fixedly connected to the two adjustment plates 4 respectively, an adjustment component is arranged on the upper end of each adjustment plate 4, and the adjustment plate 4 is connected to a transmission belt 8 through the adjustment component;

[0030] The adjustment assembly includes a support shell 9 fixedly arranged on the upper end of the adjustment plate 4, two adjustment rods 10 are symmetrically arranged in the support shell 9, a lifting seat 11 is movably provided on the adjustment plate 4, and transmission wheels 12 are rotatably provided on one side of the adjustment rod 10 and the lifting seat 11, and the three transmission wheels 12 are all connected to the transmission belt 8.

[0031] In this embodiment, when it is necessary to adjust the distance between the two transmission belts 8 according to the size of the circuit board, the first motor 5 is started, the first motor 5 drives the rotating gear 6 to rotate, the rotating gear 6 drives the two racks 7 to move in adjacent directions, the racks 7 drive the adjustment plate 4 to move along the two limit rods 3, and the adjustment plate 4 drives the transmission belt 8 to move through the adjustment assembly, thereby shortening the distance between the two transmission belts 8. On the contrary, when the first motor 5 reverses, the distance between the two transmission belts 8 increases.

[0032] More specifically, by starting the first motor 5, the two adjustment plates 4 drive the transmission belt 8 to move, thereby adjusting the distance between the transmission belts 8. When the lifting seat 11 moves upward, the lifting seat 11 drives the driven wheel thereon to move upward, at which time the transmission belt 8 becomes loose, and the two adjustment rods 10 move away from the support shell 9 along the support shell 9, and the adjustment rods 10 drive the transmission wheel 12 to move, thereby extending the transmission belt 8 and tightening it on the three transmission wheels 12.

[0033] See also Figure 1-5As an implementation method for adjusting the transmission length of the rotating belt: a driving chamber 13 is provided in the support shell 9, a bidirectional screw 14 is rotatably provided in the driving chamber 13, both ends of the bidirectional screw 14 respectively pass through the driving chamber 13 and are threadedly connected to the adjusting rod 10, a limit block 15 is fixedly provided on the upper end of the adjusting rod 10, a limit groove 16 matching the limit shell is provided on the support shell 9, a second motor 17 is fixedly provided on one side of one of the adjusting rods 10, a driving end of the second motor 17 passes through the adjusting rod 10 and is fixedly connected to the rotating wheel, a driven cone is fixedly provided on the bidirectional screw 14 in the driving chamber 13 The driven bevel gear 18 is meshedly connected with a driving bevel gear 19, and the driving bevel gear 19 is fixedly connected with a rotating rod 20. The rotating rod 20 is rotatably connected to the driving chamber 13. One end of the rotating rod 20 passes through the driving chamber 13 and is fixedly connected with a turning handle 21. A limit chamber 22 is provided on the adjustment plate 4. The lifting seat 11 is slidably connected with the limit chamber 22 through a track structure. A rotating ring 23 is rotatably provided on the upper end of the lifting seat 11. The rotating ring 23 is threadedly connected with a lead screw 24. The lead screw 24 is fixedly arranged in the limit chamber 22, and the lead screw 24 is movably connected to the lifting seat 11.

[0034] Specifically, the rotating ring 23 is rotated. Since the rotating ring 23 is threadedly connected to the lead screw 24, the rotation of the rotating ring 23 will drive the lifting seat 11 to move upward along the sliding connection with the limit chamber 22, and the lifting seat 11 drives the transmission wheel 12 to move upward, so that the transmission belt 8 becomes loose, and the turning handle 21 is turned. The turning handle 21 drives the driving bevel gear 19 to rotate, and the driving bevel gear 19 drives the driven bevel gear 18 to rotate. The driven bevel gear 18 drives the bidirectional screw 14 to rotate. The bidirectional screw 14 is provided with two threaded areas in opposite directions, so that the two adjusting rods 10 move away from the support shell 9, and the adjusting rod 10 drives the limit block 15 to move along the limit groove 16 to limit it. At the same time, the adjusting rod 10 drives the transmission wheel 12 to move, thereby extending the transmission belt 8 and tightening it on the three transmission wheels 12.

[0035] See also Figure 1-5 As an implementation method for fixing the throttle 21: a positioning plate 25 is fixedly provided on one side of the support shell 9, and a bolt 26 is threadedly connected to the positioning plate 25. One end of the bolt 26 passes through the positioning plate 25 and is rotatably connected to a clamping block 27. One side of the clamping block 27 is slidably connected to the support shell 9 through a track structure, and a gear ring 28 matching the clamping block 27 is provided on the outer side of the throttle 21.

[0036] Specifically, when the handle 21 rotates, the handle 21 drives the gear ring 28 to rotate. When the handle 21 has completed its rotation, the bolt 26 is turned. Since the bolt 26 is threadedly connected to the positioning plate 25, the bolt 26 will move in the direction of the gear ring 28 while rotating. The bolt 26 drives the block 27 to move along the sliding connection with the support shell 9 to fix the gear ring 28. The gear ring 28 limits the handle 21. The handle 21 limits the bidirectional screw 14 by driving the bevel gear 19 and the driven bevel gear 18, thereby fixing the two adjustment rods 10.

[0037] To sum up, when the overall equipment is in use:

[0038] When it is necessary to adjust the transmission length of the transmission belt 8 according to the distance between the two devices, the rotating ring 23 is rotated. Since the rotating ring 23 is threadedly connected to the lead screw 24, the rotation of the rotating ring 23 will drive the lifting seat 11 to move upward along the sliding connection with the limit chamber 22, and the lifting seat 11 drives the transmission wheel 12 to move upward, so that the transmission belt 8 becomes loose, and the turning handle 21 is turned. The turning handle 21 drives the driving bevel gear 19 to rotate, and the driving bevel gear 19 drives the driven bevel gear 18 to rotate, and the driven bevel gear 18 drives the bidirectional screw 14 to rotate. The bidirectional screw 14 is provided with two threaded areas in opposite directions, so that the two adjusting rods 10 move away from the support shell 9, and the adjusting rod 10 drives the limit block 15 to move along the limit groove 16 to limit it. At the same time, the adjusting rod 10 drives the transmission wheel 12 to move, thereby extending the transmission belt 8 and tightening it on the three transmission wheels 12.

[0039] When the transmission length of the rotating belt is adjusted, the bolt 26 is turned. Since the bolt 26 is threadedly connected to the positioning plate 25, the bolt 26 will move in the direction of the gear ring 28 while rotating. The bolt 26 drives the block 27 to move along the sliding connection with the support shell 9 to fix the gear ring 28. The gear ring 28 limits the turning handle 21. The turning handle 21 limits the bidirectional screw 14 by driving the bevel gear 19 and the driven bevel gear 18, thereby fixing the two adjustment rods 10.

[0040] When it is necessary to adjust the distance between the two transmission belts 8 according to the size of the circuit board, start the first motor 5, the first motor 5 drives the rotating gear 6 to rotate, the rotating gear 6 drives the two racks 7 to move in adjacent directions, the racks 7 drive the adjustment plate 4 to move along the two limit rods 3, and the adjustment plate 4 drives the transmission belt 8 to move through the adjustment component, thereby shortening the distance between the two transmission belts 8. On the contrary, when the first motor 5 reverses, the distance between the two transmission belts 8 increases.
