Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to an automatic turning mechanism for loading and unloading materials. Background Art

[0002] During the machining production process, the product needs to be transported to the required processing position through a conveying device. Some workpieces need to be processed on both sides. In the existing automated production equipment or inspection equipment, only one side of the product can be processed. When the other side needs to be processed, the product needs to be flipped over and transported to another processing equipment through a conveying device for processing. During the flipping and transportation process, manual flipping or flipping with a three-axis robotic arm is required. The three-axis robotic arm is equipped with a matching fixture for positioning and grasping the workpiece. The robotic arm drives the fixture to flip to achieve the purpose of transfer, but the three-axis robotic arm and the fixture require a large space in the workplace and the cost is relatively expensive. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an automatic turning mechanism for loading and unloading materials, which has a simple structure and low cost, can realize the turning of materials, and solves the disadvantages of traditional manual turning that is time-consuming and labor-intensive. During the turning process, the materials are firmly fixed, which greatly improves the working efficiency and can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: an automatic turning mechanism for loading and unloading materials, comprising a support frame, wherein two connecting rods are symmetrically arranged on the upper part of the support frame, wherein the rod body of one connecting rod is rotatably connected to the two turning arms 1, and the rod body of the other connecting rod is rotatably connected to the two turning arms 2, the lower parts of the two turning arms 1 are connected by a fixing rod 1, and the lower parts of the two turning arms 2 are connected by a fixing rod 2; a servo motor 1 is fixed to the side of the support frame through a connecting seat, and the output shaft of the servo motor 1 is connected to a rotating plate, one end of the rotating plate is hinged to the fixing rod 1 through a movable plate 1, and the other end of the rotating plate is hinged to the fixing rod 2 through a movable plate 2. When the servo motor 1 drives the rotating plate to rotate counterclockwise, the rotating plate drives the two turning arms 1 to swing through the movable plate 1, and at the same time, the rotating plate drives the two turning arms 2 to swing through the movable plate 2, the upper part of the turning arm 1 is relatively close to the upper part of the turning arm 2, and when the servo motor 1 drives the rotating plate to rotate clockwise, the upper part of the turning arm 1 is relatively far away from the upper part of the turning arm 2 and is correspondingly reset to a horizontal state.

[0005] Preferably, the sides of the flip arm 1 and the flip arm 2 are provided with slots for clamping the plate, and the rod bodies of the two connecting rods are provided with fastening components for pressing and fixing the plate on the flip arm 1 or the flip arm 2.

[0006] Preferably, the fastening assembly comprises a cylinder, a cylinder body end of the cylinder is connected to a connecting rod, and a telescopic end of the cylinder is connected to a pressing plate.

[0007] Preferably, the connecting rod is rotatably connected to the support frame, and a servo motor 2 for driving the connecting rod to rotate is provided on the side of the support frame.

[0008] Preferably, the two flip arms 1 on one of the connecting rods are located between the two flip arms 2 on the other connecting rod.

[0009] Preferably, the support frame is also symmetrically provided with two limit rods, and the flip arm 1 and the flip arm 2 are both provided with limit grooves adapted to the corresponding limit rods, and when the flip arm 1 and the flip arm 2 cooperate with the corresponding limit rods, they are both in a horizontal state.

[0010] Preferably, the movable plate 1 is located on one side of the rotating plate and is hinged to an end thereof, and the movable plate 2 is located on the other side of the rotating plate and is hinged to the other end thereof.

[0011] When the servo motor drives the rotating plate to rotate clockwise, the rotating plate drives the two flip arms to swing through the movable plate, and at the same time, the rotating plate drives the two flip arms to swing through the movable plate. The upper part of the flip arm one is relatively close to the upper part of the flip arm two. At this time, the fastening assembly on one side of the flip arm is actuated, that is, the cylinder pushes the pressure plate to extend, and the servo motor drives the connecting rod to rotate, and the pressure plate presses the plate on the flip arm one. When the flip arm one is close to the flip arm two, the fastening assembly on one side of the flip arm contracts, and the fastening assembly on the flip arm two sides extends, and then the connecting rod on the flip arm two sides rotates to push the plate on the flip arm one onto the flip arm two and press it tightly. When the servo motor drives the rotating plate to rotate clockwise, the flip arm one and the flip arm two are reset, thereby realizing the flipping of the material, solving the time-consuming and labor-intensive disadvantages of traditional manual flipping. The structure is relatively simple and the cost is low compared to the three-axis mechanical arm. The material is firmly fixed during the flipping process, which greatly improves the working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] See also Figure 1-3 , the present invention provides the following technical solutions: Example 1: See attached Figure 1-3 , an automatic turning mechanism for loading and unloading materials, comprising a support frame 1, wherein two connecting rods 8 are symmetrically arranged on the upper part of the support frame 1, wherein the rod body of one connecting rod 8 is rotatably connected to two turning arms 7, and the rod body of the other connecting rod 8 is rotatably connected to two turning arms 9, the lower parts of the two turning arms 7 are connected by a fixed rod 12, and the lower parts of the two turning arms 9 are connected by a fixed rod 13; a servo motor 2 is fixed to the side of the support frame 1 through a connecting seat, and the output shaft of the servo motor 2 is connected to a rotating plate 11, one end of the rotating plate 11 is hinged to the fixed rod 12 through a movable plate 4, and the other end of the rotating plate 11 is hinged to the fixed rod 13 through a movable plate 23; It can be understood that when the servo motor 12 drives the rotating plate 11 to rotate counterclockwise, the rotating plate 11 drives the two flip arms 17 to swing through the movable plate 14, and at the same time, the rotating plate 11 drives the two flip arms 29 to swing through the movable plate 23, and the upper part of the flip arm 17 is relatively close to the upper part of the flip arm 29. When the servo motor 12 drives the rotating plate 11 to rotate clockwise, the upper part of the flip arm 17 is relatively far away from the upper part of the flip arm 29 and is correspondingly reset to a horizontal state, that is, when the upper part of the flip arm 17 is relatively close to the upper part of the flip arm 29, the plate can be transported from the flip arm 17 to the flip arm 29; It should be noted that the sides of the flip arm 1 7 and the flip arm 2 9 are provided with a slot for clamping the plate. During the flipping process of the flip arm 1 7, the plate is leaning against the flip arm 1 7, that is, the flip arm 1 7 flips the plate to a vertical state, and the flip arm 2 9 also flips to a vertical state synchronously, and the flip arm 1 7 is staggered with the flip arm 2 9, and then the flip arm 2 9 falls, and the plate completes the flipping operation, realizing the flipping of the material, which solves the time-consuming and labor-intensive disadvantages of traditional manual flipping. The structure is relatively simple, the flipping function is easy to realize, and the cost is low.

[0016] Example 2: See attached Figure 2 , which is different from the embodiment 1, the rod bodies of the two connecting rods 8 are provided with a fastening assembly 6 for pressing and fixing the plate on the flip arm 1 7 or the flip arm 2 9, and the fastening assembly 6 includes a cylinder 6.2, the cylinder end of the cylinder 6.2 is connected to the connecting rod 8, and the telescopic end of the cylinder 6.2 is connected to the pressing plate 6.1; Furthermore, the connecting rod 8 is rotatably connected to the support frame 1, and a servo motor 5 for driving the connecting rod 8 to rotate is provided on the side of the support frame 1; During the flipping process, the fastening assembly 6 on the flipping arm 7 side is actuated, that is, the cylinder 6.2 pushes the pressing plate 6.1 to extend, and the servo motor 25 drives the connecting rod 8 on the flipping arm 7 side to rotate, and the pressing plate 6.1 presses the plate onto the flipping arm 7. When the flipping arm 7 and the flipping arm 29 are close to each other, the fastening assembly 6 on the flipping arm 7 side contracts, and the fastening assembly 6 on the flipping arm 29 side extends, and then the connecting rod 8 on the flipping arm 29 side rotates, and the plate on the flipping arm 7 is pushed onto the flipping arm 29 and pressed tightly, thereby realizing the material pushing operation and the fixing operation of the plate during the flipping process to ensure safety.

[0017] Example 3: See attached Figure 2 and Figure 3 , which is different from the embodiment 1, the two flip arms 1 7 on one connecting rod 8 are located between the two flip arms 2 9 on the other connecting rod 8, and the two flip arms 1 7 and the two flip arms 2 9 can have a partially overlapping area when they are close to each other; The support frame 1 is also symmetrically provided with two limit rods 10, and both the flip arm 1 7 and the flip arm 2 9 are provided with limit grooves adapted to the corresponding limit rods 10. When the flip arm 1 7 and the flip arm 2 9 cooperate with the corresponding limit rods 10, they are both in a horizontal state, and the positions of the flip arm 1 7 and the flip arm 2 9 are limited by the limit rods 10 to avoid excessive flipping; In addition, the movable plate 1 4 is located on one side of the rotating plate 11 and is hinged to its end, and the movable plate 2 3 is located on the other side of the rotating plate 11 and is hinged to its other end. The movable plate 1 4 and the movable plate 2 3 do not interfere with each other.
