Description

Technical Field

[0002] Electronic components are basic components in electronic technology and electronic equipment. They are usually composed of several parts and can be used in similar products. These components include but are not limited to resistors, capacitors, inductors, transistors, integrated circuits, etc. In the production factory, the components need to be plugged into the circuit board first, and then the components and circuit board need to be welded. After welding, the electronic components need to be taken out of the welding machine and sent to the inspection equipment for solder joint inspection. During the inspection, the stacked electronic components need to be automatically placed on the conveying equipment of the inspection equipment through the automatic feeding mechanism, so that the electronic component assemblies are sent to the inspection equipment for inspection through the conveying equipment, and finally the electronic component assemblies are classified according to whether there are any problems with the welding.

[0003] In the process of loading, the existing feeding mechanisms are mostly combined with conveyor belts and transport teeth to transport the circuit boards and the anti-collision sponges at the bottom one by one to complete the loading. When the spacing between the stacked circuit boards changes, it is necessary to replace the feeding mechanism with a larger spacing between the transport teeth to avoid collision of electronic components during loading. At the same time, most of the existing feeding mechanisms are fixed structures. When the size of the circuit board of the electronic components changes, it is necessary to replace the feeding mechanism of the corresponding size, which is inconvenient to adjust. Therefore, we propose an automatic feeding mechanism for electronic component conveying equipment to solve the above problems. Utility Model Content

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

[0021] See also Figure 1-5The utility model provides a technical solution: an automatic feeding mechanism of an electronic component conveying device, comprising a fixed frame 1, a first slide groove 2, a first rotating rod 3, a first threaded rod 4, a limiting clamping rod 5, a first connecting block 6, a first bevel gear 7, a second threaded rod 8, a limiting rod 9, a movable plate 10, a second rotating rod 11, a bolt 12, a horizontal placement plate 13, a movable sleeve 14, a vertical placement plate 15 and a rotating wheel 16, a first slide groove 2 is arranged at the front end of the fixed frame 1, and a first rotating rod 3 is arranged in the first slide groove 2, and a first threaded rod 4 is arranged next to the first rotating rod 3, and a first connecting rod 4 is arranged on the first rotating rod 3 and the first threaded rod 4 Block 6, and a limiting clamping rod 5 is arranged on the first rotating rod 3, and a first bevel gear 7 is arranged in the first connecting block 6, the right side of the first bevel gear 7 is connected with a second threaded rod 8 through a bevel gear, and the second threaded rod 8 is connected with a movable plate 10, and a limiting rod 9 is penetrated through the rear side of the movable plate 10, a second rotating rod 11 is arranged in the movable plate 10, and a horizontal placement plate 13 is connected to the bottom of the second rotating rod 11, and a movable sleeve 14 is arranged on the horizontal placement plate 13, a bolt 12 is arranged outside the movable sleeve 14, and a vertical placement plate 15 is connected to the movable sleeve 14, and a rotating wheel 16 is arranged on the horizontal placement plate 13 and the vertical placement plate 15.

[0022] The first connecting block 6 is threadedly connected to the first threaded rod 4, so that the first connecting block 6 moves by rotating the first threaded rod 4, and is connected to the first rotating rod 3 through the first bevel gear 7 and the rotating shaft, so that the first bevel gear 7 can be driven by the limiting clamping rod 5 on the first rotating rod 3 to rotate through the rotation of the first rotating rod 3, thereby driving the second threaded rod 8 connected to it through the bevel gear to rotate further with the rotation of the first rotating rod 3, and the first threaded rod 4 is a double-threaded structure, so that the first connecting block 6 can move in the opposite direction, thereby allowing the second threaded rod 8 connected to it through the rotating shaft to move inward in the opposite direction.

[0023] The second threaded rod 8 forms a rotating structure with the first bevel gear 7 via a rotating shaft and a bevel gear, so that the second threaded rod 8 can rotate along with the rotation of the first bevel gear 7 .

[0024] The movable plate 10 forms a threaded movable structure on the second threaded rod 8 through the second threaded rod 8 and the limiting rod 9, and the second threaded rod 8 is a double-threaded structure, so that the movable plate 10 can move in opposite directions on the second threaded rod 8 through threaded connection, and is limited by the limiting rod 9 to avoid self-rotation.

[0025] The vertical placement plate 15 forms a movable structure on the second rotating rod 11 through a movable sleeve 14 and a bolt 12, so that the movable sleeve 14 and the vertical placement plate 15 connected thereto are fixed by the bolt 12 when sliding on the second rotating rod 11, which facilitates the adjustment of the hardware of the horizontal placement plate (13) and the vertical placement plate (15) to adapt to stacked circuit boards with different spacings.

[0026] The horizontal placement plates 13 and the vertical placement plates 15 are staggered and arranged in a "cross" shape, so that when the stacked circuit boards are moved downward by gravity, the circuit boards can be placed on the electronic component conveying equipment in an orderly manner, achieving the effect of automatic loading.

[0027] Working principle: When using the automatic feeding mechanism of the electronic component conveying equipment, first, start the motor outside the first threaded rod 4, so that the rotation of the first threaded rod 4 drives the first connecting block 6 connected thereto by threads to move inward or outward until it reaches the same distance as the width of the circuit board, and stops rotating. Then start the motor outside the first rotating rod 3, so that the limiting clamping rod 5 outside the first rotating rod 3 drives the first bevel gear 7 in the first connecting block 6 to rotate through the rotation of the first rotating rod 3, thereby driving the second threaded rod 8 connected thereto by the bevel gear to rotate, so that the movable plate 10 limited by the limiting rod 9 of the second threaded rod 8 drives the double-threaded second threaded rod 8 to move closer or apart until the length of the circuit board to be transported is reached;

[0028] Then, the bolts 12 on the movable sleeve 14 at the bottom of the second rotating rod 11 are rotated respectively to open the restriction of the movable sleeve 14, thereby driving the vertical placement plate 15 to adjust its position upward or downward, so that the spacing between the horizontal placement plate 13 and the vertical placement plate 15 can be adjusted, thereby adapting to the spacing between the stacked circuit boards that need to be transported, and then directly put the stacked circuit boards in, start the motor on the movable plate 10 to make the second rotating rod 11 start to rotate, and the circuit boards will fall from the horizontal placement plate 13 to the conveying equipment at the bottom of the loading structure due to gravity, and the circuit boards on the upper side will fall on the rotated vertical placement plate 15, and then the first circuit board will fall on the conveying equipment after it is rotated again, and then it will be reciprocated in sequence, thereby automatically loading the electronic components, and the contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
