DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 A board loading device for SMT patch processing includes a workbench 1, a conveying mechanism 2 is arranged in the top of one side of the workbench 1, a plurality of columns 3 are arranged on the top of the other side of the workbench 1, a same top plate 4 is arranged on the plurality of columns 3, a telescopic cylinder 5 is arranged on the top plate 4, a telescopic end of the telescopic cylinder 5 is slidably installed in the top plate 4, a connecting plate 6 is movably connected to the telescopic end of the telescopic cylinder 5, a plurality of vertically distributed loading plates 7 are arranged on the bottom end of the connecting plate 6, and each loading plate 7 is close to the conveying mechanism 2. A discharge plate 8 is rotatably installed in one end of the feeding mechanism 2, a lap block 9 is provided at one end of the discharge plate 8, a positioning block 10 is provided in the loading plate 7, and the positioning block 10 is located below the lap block 9. Two mounting plates 11 are provided on the top of the side of the workbench 1 away from the conveying mechanism 2, and a slide groove 12 is provided on the two mounting plates 11, and a first spring 13 is provided in each slide groove 12, and a moving block 14 is provided on the two first springs 13, and the same stopper 15 is provided between the two moving blocks 14.

[0024] Start the telescopic cylinder 5, so that the connecting plate 6, the loading plate 7 and the unloading plate 8 descend at the same time, and the overlap block 9 follows the decline and gradually approaches the stopper 15. The continuously descending overlap block 9 is restricted by the stopper 15, so that the unloading plate 8 gradually rotates upward, so that the circuit board gradually slides down onto the conveying mechanism 2. When the overlap block 9 is affected by the rotation of the unloading plate 8 and gradually separates from the stopper 15, the unloading plate 8 rotates under the action of gravity, so that the overlap block 9 overlaps with the positioning block 10. At this time, the stopper 15 is located above the first overlap block 9, and the unloading plate 8 is rotated one by one.

[0025] Specifically, in the present embodiment, a connecting block 16 is provided on the telescopic end of the telescopic cylinder 5, and second springs 17 are provided on both sides of the connecting block 16, and a slider 18 is provided on each second spring 17, and a pressing block 19 is provided at one end of the slider 18, and a clamping block 20 is provided at the other end of the slider 18. A connecting sleeve 21 is provided on the top end of the connecting plate 6, and the connecting sleeve 21 is sleeved on the connecting block 16, and the clamping block 20 is clamped in the outer wall of the connecting sleeve 21.

[0026] After the circuit board is placed on the discharge plate 8, the connecting plate 6, the loading plate 7 and the discharge plate 8 are all located below the workbench 1. At this time, a trolley can be placed underneath and the pressing block 19 is pressed to cause the slider 18 to push the second spring 17 to be compressed. At the same time, the clamping block 20 is retracted into the connecting block 16, thereby releasing the lock between the connecting sleeve 21 and the connecting block 16, thereby realizing the overall removal of the connecting plate 6, the loading plate 7 and the discharge plate 8, and replacing them with the connecting plate 6, the loading plate 7 and the discharge plate 8 containing the circuit boards.

[0027] Specifically, in this embodiment, the outer wall of the block 20 close to the connecting sleeve 21 is inclined, so that when the connecting plate 6, the loading plate 7 and the unloading plate 8 are replaced, the block 20 can be directly inserted into the connecting sleeve 21 without manually pressing the pressing block 19 again.

[0028] Specifically, in this embodiment, a plurality of rollers 22 are rotatably mounted in the top of each unloading plate 8, and the rollers 22 make the circuit board tilt and slide more smoothly.

[0029] Specifically, in this embodiment, a lap groove 23 is provided at the bottom end of the lap block 9, and the positioning block 10 is located in the lap groove 23. The width of the lap groove 23 is greater than the specification of the positioning block 10, so as to prevent the lap block 9 from being restricted by the positioning block 10 during circular motion, resulting in obstructed rotation.

[0030] Specifically, in this embodiment, a positioning rod 24 is provided between the inner walls at both ends of the slide groove 12, the positioning rod 24 is located inside the first spring 13, the moving block 14 is slidably mounted on the outer wall of the positioning rod 24, and the positioning rod 24 prevents the moving block 14 from separating from the mounting plate 11.

[0031] Specifically, in this embodiment, the top end of the stopper 15 is planar, and the bottom end of the stopper 15 is inclined.

[0032] When the connecting plate 6, the loading plate 7 and the unloading plate 8 are replaced, the telescopic cylinder 5 is driven to gradually raise the connecting plate 6, the loading plate 7 and the unloading plate 8. When the bottom end of the stopper 15 contacts the overlap block 9, the inclined surface of the stopper 15 makes itself shrink between the two mounting plates 11, and the moving block 14 pushes the first spring 13 to compress, ensuring that the connecting plate 6, the loading plate 7 and the unloading plate 8 can rise smoothly, thereby starting a new round of plate loading operation.

[0033] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
