Description

Technical Field

[0001] This utility model belongs to the field of automated material handling technology, and in particular relates to a crank-connecting rod type material handling mechanism. Background Technology

[0002] With the rapid rise of automation, automated machinery has replaced manual material handling in industrial production. The existing method involves controlling a drive source (such as a motor) to rotate forward and backward via electrical signals, causing a suction cup assembly to move back and forth. However, this method has the following problems:

[0003] 1. Because the motor needs to frequently rotate in both directions at high speed, this not only places high demands on the motor, but also makes it very easy to damage the motor.

[0004] 2. Since the motor is controlled by electrical signals, and there is usually a certain time delay in the control of positive and negative electrical signals, it will affect the work efficiency. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this invention provides a crank-connecting rod type material handling mechanism. This invention eliminates the need for forward and reverse motor rotation and avoids the time delay problem caused by forward and reverse electrical signal control.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A crank-connecting rod type material handling mechanism includes a crank wheel driven unidirectionally by a power source. The crank wheel is connected to a crank-connecting rod assembly via a first rotating shaft. The crank-connecting rod assembly is connected to a rotating rod, which drives the rotating rod to swing bidirectionally. The rotating rod is fixedly connected to a material handling structure.

[0008] Preferably, the crank-connecting rod assembly includes a rotating handle, a rocker arm, and a grooved rod. The rocker arm is provided with a slide rail. One end of the rotating handle is fixedly connected to one end of the first rotating shaft, and the other end of the rotating handle is slidably connected to the slide rail. One end of the grooved rod is slidably connected to the slide rail, and the other end of the grooved rod is fixedly connected to the rotating handle.

[0009] Preferably, the length of the slide rail is greater than twice the length of the rotating handle, and the distance from the rotation center of the rotating handle to both ends of the rocker arm along the length direction of the slide rail is greater than the length of the rotating handle.

[0010] Preferably, the mechanism further includes a mounting frame, which includes a first upright, a second upright, and a fixing member. The first upright and the second upright are both vertically arranged, and the top ends of the first upright and the second upright are fixedly connected to the fixing member. The rotation center of the rotating handle and the rotation center of the rocker arm are both located on the first upright, and the rotation center of the rotating rod is located on the second upright.

[0011] Preferably, the fixing member is C-shaped, and the two ends of the fixing member are connected by horizontally set fixing rods; the part removal structure includes a vertically set guide rod, a sliding member slidably connected to the guide rod, and a suction cup assembly installed at the bottom of the sliding member. The guide rod is slidably connected to the fixing rod through a sliding sleeve. The sliding member is provided with a locking block, and the rotating rod can be rotatably engaged with the locking block on the sliding member.

[0012] Preferably, the mechanism also includes a base, on which the bottom end of the first upright is fixedly mounted.

[0013] Preferably, the first rotating shaft passes through the first upright, and the two ends of the first rotating shaft are respectively connected to a crank wheel and a rotating handle.

[0014] The advantages of this utility model are:

[0015] This invention transforms circular motion into complex motion, eliminating the need for signal control to reverse the motor, thus reducing the requirements on the motor, ensuring its service life, and enabling high-speed material handling, enriching automated material handling mechanisms.

[0022] like Figure 1-4As shown, a crank-connecting rod type material handling mechanism includes a mounting frame, which consists of a fixing member 8 and two vertically arranged first uprights 5 and second uprights 7. The tops of the first uprights 5 and the second uprights 7 are fixedly connected to the fixing member 8, and the bottom of the first uprights 5 is fixed to the base 14 to fix the entire mechanism. A rocker arm 3 and a rotating handle 2 are connected sequentially from bottom to top to the first uprights 5, and both the rocker arm 3 and the rotating handle 2 can rotate relative to the first uprights 5. The three are located in different planes, and the plane of rotation of the rotating handle 2 is located between the rocker arm 3 and the first uprights 5.

[0023] Specifically, a first rotating shaft runs through the first upright 5, with crank wheel 1 and rotating handle 2 connected to its two ends respectively. This allows crank wheel 1 to drive rotating handle 2 to rotate in one direction under the unidirectional rotation of the motor. The other end of rotating handle 2 is slidably mounted in the slide rail 15 of rocker arm 3. One end of rocker arm 3 is rotatably mounted on the first upright 5. The length of slide rail 15 is greater than twice the length of rotating handle 2, and the distance between the rotation center of rotating handle 2 and both ends of rocker arm 3 along the length of slide rail 15 is greater than the length of rotating handle 2. When rotating handle 2 rotates, it can drive rocker arm 3 to swing left and right.

[0024] Furthermore, the slide rail 15 is slidably connected to one end of the groove rod 4, and the other end of the groove rod 4 is fixedly connected to one end of the second rotating shaft. The second rotating shaft passes through the second upright rod 7, and the other end of the second rotating shaft is fixedly connected to one end of the rotating rod 6. This allows the groove rod 4 to slide within the slide rail 15 and swing left and right when the rocker arm 3 swings. Consequently, the groove rod 4 drives the rotating rod 6 to swing left and right around the second rotating shaft as the center point. The other end of the rotating rod 6 is engaged with a locking block on the sliding member 12. A guide rod 11 passes through the sliding member 12, allowing it to slide up and down along the vertically arranged guide rod 11. The fixing member 8 is C-shaped, with its two ends connected by a horizontally arranged fixing rod 9, forming a ring. The guide rod 11 is slidably connected to the fixing rod 9 via a sliding sleeve 10. When the rotating rod 6 swings, the sliding member 12 slides up and down along the length of the guide rod 11, providing a horizontal force to the guide rod 11, driving the sliding sleeve 10 to slide on the fixing rod 9. Consequently, the suction cup assembly 13 fixed to the bottom of the sliding member 12 can perform an arc-shaped movement, as shown in the following path. Figure 4 As shown.

[0025] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
