Description

Technical Field

[0001] The utility model relates to a connecting rod type quick linkage mechanism, belonging to the field of automatic logistics conveying and sorting. Background Art

[0002] At present, the logistics industry has achieved unprecedented development, especially in the centralized loading and unloading and transportation of logistics parts. Transport vehicles from all directions transport logistics parts to the logistics center. A large number of logistics parts need to be moved to different sites first, and then identified and classified. The transportation of logistics parts is mostly carried out with the help of conveyor belts, but the transportation efficiency of a conveyor belt is limited, and it is often necessary to use multiple conveyor belts to divert and transport logistics parts. The Chinese invention patent with patent number CN201610289223.3 provides a system and method for the separation and confluence of logistics automated conveyor lines, which allows the goods to be as close to the sorting mechanism as possible, ensuring the success of sorting and greatly improving efficiency.

[0003] However, the inventor of the utility model found that the existing technology has the following problems: the current logistics sorting system needs to have a diversion mechanism when transporting at the intersection of the conveyor line, which is costly and the driving O-belt is easily damaged and broken. In addition, some boxes (cartons or turnover boxes) need to be transported sideways in certain specific occasions. Therefore, it is necessary to design a mechanism to achieve the above functions. Summary of the invention

[0004] In order to solve the above technical problems, the utility model provides a connecting rod type quick linkage mechanism, which can solve the problem of quick diversion or sideways transportation of goods during sorting.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a connecting rod type quick linkage mechanism, comprising a light rod, a transmission assembly, a fulcrum assembly and a power assembly; the shaft end of the power assembly is fixedly connected with the transmission assembly; the end of the transmission assembly is rotatably connected to the surface of the light rod through a pin shaft; the end of the light rod is rotatably connected to the fulcrum assembly; the power assembly comprises a micro motor, a first L-shaped mounting plate and a first L-shaped fixing plate; the first L-shaped mounting plate is fixed to the first L-shaped fixing plate, and the first L-shaped fixing plate is fixedly connected to a conveyor line; the output shaft of the micro motor passes through the first L-shaped mounting plate and is connected to the end of the transmission assembly; the transmission assembly comprises a first swing rod, a second swing rod, a clamping block, a first pin and a second pin; the first swing rod is rotatably connected to one end of the second swing rod through the first pin.

[0007] The other end of the second swing rod is connected to the clamping block through a second pin; the clamping block is clamped on the surface of the polished rod through a screw.

[0008] The transmission assembly also includes a switch bracket, an infrared detection switch and a limit block; the bottom surface of the switch bracket is fixed to the surface of the first L-shaped mounting plate, and the upper surface is provided with an arc groove, and the infrared detection switch is threadedly fixed in the arc.

[0009] The switch bracket has limit blocks symmetrically fixedly connected on both sides.

[0010] The fulcrum assembly comprises a bearing seat, a second L-shaped fixing plate, a vertical shaft and a second L-shaped mounting plate; the end of the light rod passes through a radial through hole on the vertical shaft; and the bottom end of the vertical shaft is rotatably connected to the bearing seat.

[0011] The bottom surface of the bearing seat is fixed on the surface of the second L-shaped fixing plate; the surface of the second L-shaped fixing plate is fixed on the surface of the second L-shaped fixing plate; and the bottom surface of the second L-shaped fixing plate is fixed on the streamline.

[0012] The swing angle of the polished rod ranges from 0 to 45 degrees.

[0013] The beneficial effect of the utility model is that the connecting rod assembly is driven by a motor so that the light rod can swing a certain angle on the streamline, so that the conveyed parts can move along the inner edge of the streamline, thereby solving the problem of rapid diversion or side conveying during cargo sorting.

The light rod 4 is an actuator for pushing the logistics part to move to the side; the transmission assembly 11 is used to provide connection transmission; the fulcrum assembly 12 is the action origin of the light rod 4; the power assembly 13 is used to provide power to make the logistics part move to the side. The micro motor 1 provides rotational power to the light rod 4; the first L-shaped mounting plate 10 is used to connect and fix the micro motor 1 and the switch bracket 3; the first L-shaped fixing plate 14 is a supporting skeleton part.

[0021] The other end of the second swing rod 6 is connected to the clamping block 7 through the second pin 16; the clamping block 7 is clamped on the surface of the light rod 4 by screws; the first swing rod 2 and the second swing rod 6 are both connecting rods, and form a connecting rod mechanism with the first pin 15 for transmitting the torque of the micro motor 1; the first pin 15 and the second pin 16 are rotating joints; the clamping block 7 is used to clamp the light rod 4.

[0022] The transmission assembly 11 also includes a switch bracket 3, an infrared detection switch 5 and a limit block 17; the bottom surface of the switch bracket 3 is fixed to the surface of the first L-shaped mounting plate 10, and the upper surface is provided with an arc groove, and the infrared detection switch 5 is threadedly fixed in the arc; the switch bracket 3 is used to install the infrared detection switch 5, and the arc groove thereon can flexibly determine the installation position of the infrared detection switch 5; the infrared detection switch 5 is used to detect whether the first swing arm 2 is in place.

[0023] The switch bracket 3 is symmetrically and fixedly connected with limit blocks 17 on both sides. The limit blocks 17 are used to limit the extreme position of the first swing rod 2.

[0024] The second embodiment of the utility model is basically the same as the first embodiment, mainly in further optimization. The fulcrum assembly 12 includes a bearing seat 8, a second L-shaped fixing plate 9, a vertical shaft 18 and a second L-shaped mounting plate 19; the end of the light rod 4 passes through the radial through hole on the vertical shaft 18; the bottom end of the vertical shaft 18 is rotatably connected to the bearing seat 8; the bearing seat 8 ensures that the vertical shaft 18 rotates smoothly; the vertical shaft 18 is used to change the installation direction of the light rod 4; the second L-shaped mounting plate 19 is used to install and fix the bearing seat 8; the second L-shaped fixing plate 9 is the supporting frame of the fulcrum assembly 12.

The limit block 17 installed on the switch bracket 3 can limit the extreme position of the first swing arm 2. At the same time, the infrared detection switch 5 detects whether the first swing arm 2 reaches the extreme position. Due to the limit of the extreme position, the rotation angle of the light rod 4 around the bearing seat 8 is 0-45°, which can push the goods on the streamline to another streamline, or push the goods to the side of the streamline for transportation.
