Description

Technical Field

[0001] This utility model relates to the field of machine vision automated inspection equipment, and in particular to a rotary clamping and conveying device. Background Technology

[0002] In automated inspection processes, conveying devices are often used to transport the objects to be inspected to various workstations for inspection and sorting. When inspecting ring-shaped parts, such as various bearing rings, seals and other precision components, the market demand for such parts is gradually increasing with the development of technology and industry, and there will be inspection needs for various parts with different specifications.

[0003] Existing technology uses a ring conveyor for transport. First, grippers clamp the object to be inspected, then rotate and transport it for subsequent inspection. Multiple clamping stations use multiple cylinders, each actuated individually by a set of solenoid valves. Since each cylinder only has two positions (front and rear), but there are many types of products to be inspected, multiple grippers need to be replaced in batches for each new type of object. This is not only costly and cumbersome, but also increases the burden of classification and management. Utility Model Content

[0004] This utility model is proposed in view of the above-mentioned technical problems, and provides a rotary clamping and conveying device. It adopts a double turntable structure. First, the rotation of the first turntable drives multiple clamping mechanisms on the second turntable to perform clamping actions. The clamping space of the multiple clamping mechanisms is controlled by the rotation amplitude of the first turntable to adapt to the detection objects of different specifications. This not only effectively reduces costs, but also improves work efficiency.

[0005] According to a first aspect of the present invention, a rotary clamping and conveying device is provided, comprising: a first motor, a first turntable, a second motor, and a second turntable, wherein the second turntable is a hollow annular disc, and the first turntable is located at the center of the second turntable;

The first motor drives the first turntable to rotate so as to drive the clamping mechanisms to clamp the workpiece. The second motor drives the second turntable to rotate so as to rotate and transport the workpiece clamped by the clamping mechanisms.

[0007] According to a second aspect of the present invention, a rotary clamping and conveying device as described in the first aspect is provided, wherein a first turntable is provided with elongated openings corresponding to each clamping mechanism; the clamping mechanism includes a first jaw and a second jaw, one end of the first jaw is fixedly mounted on a first movable block, one end of the second jaw is fixedly mounted on a second movable block, the other end of the first movable block connected to the first jaw is hinged to a first connecting rod, the other end of the second movable block connected to the second jaw is hinged to a second connecting rod, the first connecting rod and the second connecting rod are jointly hinged to a first connecting block, and the other end of the first connecting block that is hinged to the first connecting rod and the second connecting rod is slidably connected in the opening via a pulley.

[0008] With this structure, the rotation of the first turntable causes the pulley to slide within the opening. The sliding pulley drives the first connecting block forward, which in turn pushes the hinged first and second connecting rods to move the first and second moving blocks to the sides. Then, the first and second grippers open to clamp the object to be detected.

[0009] According to a third aspect of the present invention, a rotary clamping and conveying device as described in the first aspect is provided, wherein a first turntable is hinged with a third link corresponding to each clamping mechanism; the clamping mechanism includes a third jaw and a fourth jaw, one end of the third jaw is fixedly mounted on a third moving block, one end of the fourth jaw is fixedly mounted on a fourth moving block, the other end of the third moving block connected to the third jaw is hinged to a fourth link, the other end of the fourth moving block connected to the fourth jaw is hinged to a fifth link, the third link and the fourth link are jointly hinged to a second connecting block, and the other end of the second connecting block that is hinged to the fourth link and the fifth link is hinged to the third link.

[0010] With this structure, the rotation of the first turntable drives the movement of each third link. The moving third link drives the second link forward, which in turn pushes the hinged fourth and fifth links to move the third and fourth moving blocks to both sides. Then the three grippers and the fourth gripper open to clamp the object to be detected.

[0011] According to a fourth aspect of the present invention, a rotary clamping conveying device as in the second aspect is provided, wherein a first moving block is disposed on one side of a horizontally arranged first slide rail via a first slide groove, and a second moving block is disposed on the other side of the horizontally arranged first slide rail via a second slide groove.

[0012] This structure allows the first and second moving blocks to slide more smoothly and steadily on the slide rails as they move to the sides, thus promoting smoother opening of the grippers.

[0013] According to a fifth aspect of the present invention, a rotary clamping and conveying device as described in the third aspect is provided, wherein a third moving block is disposed on one side of a transversely arranged second slide rail via a third sliding groove, and a fourth moving block is disposed on the other side of the transversely arranged second slide rail via a fourth sliding groove.

[0014] According to a sixth aspect of the present invention, a rotary clamping conveying device as described in the second aspect is provided, wherein the connecting block is disposed on a vertically arranged second slide rail via a third slide groove.

[0015] This structure allows the blocks to slide more smoothly and steadily on the slide rail as they are pushed forward, promoting smoother opening of each gripper.

[0016] According to a seventh aspect of the present invention, a rotary clamping conveying device as described in the third aspect is provided, wherein the second connecting block is disposed on a vertically arranged fourth slide rail via a sixth slide groove.

[0017] According to an eighth aspect of the present invention, a rotary clamping and conveying device as described in the first aspect is provided, wherein the first motor is a servo motor, the servo motor is connected to a reducer, and the reducer is connected to the first turntable.

[0018] This structure allows for effective control of the rotation amplitude of the first turntable, enabling fine-tuning of the clamping space of each gripper to accommodate objects of different sizes.

[0019] The beneficial effects of this utility model are as follows: the rotation of the first turntable synchronously controls the clamping mechanisms of multiple stations on the second turntable, and the accommodating space of each clamping mechanism is adjusted by the rotation amplitude to accommodate various objects, reducing the configuration of various cylinders and solenoid valves, reducing costs, avoiding batch replacement of multiple clamping mechanisms when testing different types of test objects, and improving efficiency.

[0030] Figure 5 This is a partial schematic diagram of the clamping mechanism of the rotary clamping conveying device of this utility model. (See attached diagram.) Figure 1 , 5According to one embodiment of this utility model, the turntable 2 is hinged with connecting rods corresponding to each clamping mechanism, and one connecting rod 6 is marked in the figure. Each clamping mechanism 5 includes a jaw 51 and a jaw 52. One end of the jaw 51 is fixedly mounted on a moving block 53, and one end of the jaw 52 is fixedly mounted on a moving block 54. The other end of the moving block 53 is hinged to a connecting rod 55, and the other end of the moving block 54 is hinged to a connecting rod 56. The connecting rods 55 and 56 are hinged together on a connecting block 57, and the other ends of the connecting rods 55 and 56 are hinged to the connecting rod 6. Thus, the rotation of the turntable 2 drives the connecting rods 6 to move. The moving connecting rods 6 drive the connecting block 57 forward, which in turn pushes the hinged connecting rods 55 and 56 to move the moving blocks 53 and 54 to both sides.

Figure 4 This is a schematic diagram of the clamping state of the jaws in the second embodiment of the rotary clamping and conveying device of this utility model. Figure 5 This is a partial schematic diagram of the clamping mechanism of the rotary clamping conveying device of this utility model. (See attached diagram) Figure 2-5 According to another embodiment of this utility model, the turntable 2 is provided with elongated openings corresponding to each clamping mechanism, and one of the openings 7 is marked in the figure.

The connecting rods 55 and 56 are hinged together on a connecting block 57. The other ends of the connecting rods 55 and 56 are slidably connected to the opening 7 via a pulley 8. Thus, the rotation of the turntable 2 causes the pulley 8 to slide within the opening 7. The sliding pulley 8 drives the connecting block 57 forward, which in turn pushes the hinged connecting rods 55 and 56 to move the moving blocks 53 and 54 to both sides. Subsequently, the jaws 51 and 52 open to clamp the object to be tested 001.

Through the cooperation of the sliding groove and the slide rail, the movement of the moving blocks 53 and 54 to both sides is made smoother and more stable on the slide rail 58, promoting the smooth opening action of each gripper. Preferably, the connecting block 57 is disposed on the vertically arranged slide rail 59 via a third sliding groove, making the sliding of the connecting block 57 on the slide rail 59 smoother and more stable during the pushing process, further promoting the smooth opening action of each gripper.
