Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automated handling equipment, in particular to an industrial adsorption type handling manipulator. BACKGROUND

[0002] At present, in the field of industrial automation handling and material assembly, adsorption type manipulators are widely used for handling and positioning of sheet-shaped, plate-shaped or flat-surface materials. In the prior art, adsorption type handling manipulators usually rely on vacuum suction cups or negative pressure adsorption devices to achieve preliminary grabbing of materials, having the advantages of simple structure and convenient control. However, the prior art generally has the following problems: Most of the existing adsorption type manipulators only rely on suction cup negative pressure adsorption to achieve material grabbing, and when the material shape is irregular or there is a slight deviation, the adsorption surface is easy to be eccentric or inclined, resulting in insufficient stability during handling. Especially during fast handling or transfer, the material may slip or fall due to inertia or air pressure fluctuation.

[0003] Most of the conventional adsorption type manipulators adopt rigid suction cup structure or simple auxiliary clamping structure, and cannot be flexibly adjusted for materials of different thicknesses or edge shapes. When the material thickness is large or there is a slight surface unevenness, the clamping action may cause excessive stress and damage the material, or the clamping may fail to be in place, resulting in handling failure. At the same time, the manipulator without self-adaptive clamping function cannot accommodate both thin sheets and thick workpieces, and the application range is limited.

[0004] The existing adsorption manipulator usually opens and closes the vacuum air path through an external electromagnetic valve or a manual valve, which is complicated to operate and has slow response speed. During material handling, the air path cannot be automatically linked with the action, resulting in reduced adsorption efficiency. In addition, after the suction cup frequently contacts the material, the external air path is easy to suck in dust or impurities, causing air cavity pollution and increasing maintenance difficulty.

[0005] In summary, the existing adsorption type handling manipulator generally has the problems of single positioning, poor clamping adaptability, low automation level and easy air path pollution, and cannot meet the needs of high efficiency, high stability and multi-specification compatible handling operation in industrial production. Therefore, there is an urgent need for a new industrial adsorption type handling manipulator which can simultaneously realize adsorption positioning, mechanical centering and flexible clamping locking, and has automatic air path linkage control, to improve the reliability and efficiency of material handling.

[0040] In the embodiment, the valve core 232 is provided with a through hole matched with the valve hole 221, and the top surface is provided with a spring arranged relative to the column pin 231; the movement of the valve core 232 can realize the opening and plugging of the ring air cavity 211 and the exhaust ring cavity 212; in the connected state, the bottom surface of the linkage ring 230 is located in the same plane as the bottom surface of the guide column 300.

[0041] Through the above technical scheme, automatic linkage control of the adsorption airflow and mechanical movement is realized, the adsorption opening and the material contact are synchronized, the air path is automatically closed after the material is separated, the energy consumption is reduced, and internal pollution is prevented.

[0042] In the embodiment, the ring air cavity 211, the exhaust ring cavity 212 and the linkage ring 230 are all annular; the valve holes 221 are uniformly distributed along the circumferential direction of the air distribution ring 220; the interface 213 is fixedly installed on the surface of the ring seat 210 and is communicated with the external air pump.

[0043] Through the above technical scheme, the annular air cavity design and the uniformly distributed valve holes 221 ensure uniform distribution of the adsorption airflow, avoid local negative pressure imbalance to cause material deviation, and improve adsorption stability.

[0044] In the embodiment, the exhaust ring cavity 212 is inclined to the top surface of the air guide disc 310; the air guide disc 310 and the top surface of the linkage ring 230 are horizontally arranged; and the linkage ring 230 is sleeved on the outer periphery of the guide column 300.

[0046] In the embodiment, the guide column 300 is provided with a thread on the surface, which is matched with the thread inside the adsorption disc assembly 200; the top surface of the adsorption disc assembly 200 is provided with a threaded ring, which is connected with the bottom surface of the execution end seat 100; and the initial height of the adsorption disc assembly 200 can be adjusted to adapt to different thicknesses of the material.

[0047] Through the above technical scheme, the height of the adsorption disc assembly is adjusted through the thread to adapt to different thicknesses of the material, so that the locking claw 110 can effectively clamp the outer edge in the adsorption state, and the versatility and adaptability of the mechanical hand are improved.

[0048] The working principle and use process of the present application are as follows: The industrial adsorption type conveying manipulator of the present application adopts the double positioning and clamping principle of "adsorption + mechanical centering + clamping locking", and the core mechanism is as follows: Suction positioning principle: the suction cup assembly 200 forms an airflow channel through the ring seat 210, the air distribution ring 220, the linkage ring 230, and the air guide disc 310; when an external air pump supplies air to the interface 213, the airflow is input into the ring air cavity 211, the valve hole 221, and the through hole of the valve core 232, and then is guided out to the exhaust ring cavity 212; the airflow is guided out radially in parallel to the bottom surface of the ring seat 210 through the air guide disc 310, and the Bernoulli principle is used to achieve adsorption and fixation on the surface of the material.

[0049] Mechanical clamping principle: when the top pin 413 contacts the surface of the material, the suction cup assembly 200 and the guide column 300 continue to move downward, so that the core rod assembly 400 moves upward relative to the top pin 413, the supporting rod part 410 and the guide cone 412 push the top rod 120 to slide outward in the radial direction; the outward movement of the top rod 120 drives the locking jaw 110 to deflect around the connection point on the surface of the end seat 100 as the fulcrum, so as to contact the outer edge of the material, push the material to the center, or clamp and position the edge of the material in the adsorption force generated by the suction cup assembly 200 and the guide column 300; at the same time, the supporting rod part 410 lifts the supporting lug rod 130 through the arc lug groove 411, so that the supporting lug rod 130 is away from the surface of the locking jaw 110, facilitating the deflection of the locking jaw 110; when the airflow stops, the material is separated from the bottom surface of the guide column 300, and the supporting rod part 410 moves downward under the effect of gravity of the core rod assembly 400, the supporting lug rod 130 is guided to return to the original position by the arc lug groove 411, the locking jaw 110 is ejected to reset, and the clamping is released.

[0050] Airflow and clamping linkage control principle: the valve core 232 can control the opening and plugging of the ring air cavity 211 and the exhaust ring cavity 212 under the pre-tightening force of the spring; when the linkage ring 230 is pushed to the same horizontal position as the bottom surface of the guide column 300, the through hole of the valve core 232 and the valve hole 221 are coincided, and the adsorption function is opened; when the linkage ring 230 is elastically returned after the material is separated, the valve core 232 closes the channel under the action of the spring, so as to avoid the internal pollution of the air cavity.

[0051] In summary, the robot realizes preliminary positioning through air adsorption, and realizes stable material carrying by using the radial driving of the locking jaw to center the material or clamping the material, which takes into account rigid clamping and flexible elastic support.
