Description

Technical Field

[0001] The utility model relates to the field of mechanical arm clamps, and more specifically to an automatic stacking device for storing refractory materials. Background Art

[0002] Refractory materials are used in various fields of the national economy, such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electricity, and military industry. They are essential basic materials to ensure the production and operation of the above industries and the technological development, and they play an irreplaceable and important role in the development of high-temperature industrial production. Refractory materials include refractory bricks according to different product types. In order to improve the production and processing efficiency of refractory bricks, automatic stacking equipment is generally used to stack the produced refractory bricks to facilitate the subsequent packaging and transportation.

[0003] The existing equipment for stacking refractory bricks includes robotic arm stacking equipment. The end of the robotic arm is equipped with a clamp or a negative pressure suction cup for directly clamping or adsorbing the formed refractory bricks for transportation and stacking. Although the negative pressure suction cup can adsorb the refractory bricks for transportation, the dust on its surface is usually easily adsorbed into the negative pressure suction pipe. Over time, the adsorption force of the negative pressure suction cup is affected and the frequency of maintenance and inspection is increased. It is inconvenient to use. Therefore, we propose an automatic stacking device for refractory material storage to solve the above-mentioned problems. Utility Model Content

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figure 1-Figure 6 An automatic stacking device for storing refractory materials comprises a mechanical arm 1 and a clamp 2, wherein the clamp 2 is fixedly installed at one end of the mechanical arm 1, a three-way solenoid valve 3 is also fixedly installed on the mechanical arm 1, and a negative pressure suction pipe 4 and a positive pressure blowing pipe 5 are fixedly installed on one side of the three-way solenoid valve 3, and a connecting hose 6 is fixedly installed on the other side of the three-way solenoid valve 3;

[0031] The fixture 2 includes a housing 7 fixedly mounted on one end of the mechanical arm 1, a partition plate 8 and a fixed plate 9 are fixedly mounted inside the housing 7, a plurality of air pressure switching mechanisms 10 with the same structure are fixedly mounted between the fixed plate 9 and the housing 7, the interior of the housing 7 is separated into an air pressure communication chamber 701 by the partition plate 8, and one end of the connecting hose 6 is connected to the interior of the air pressure communication chamber 701;

[0032] The air pressure switching mechanism 10 includes a sleeve 11 installed between the fixed plate 9 and the outer shell 7, a telescopic tube 12 is slidably connected inside the sleeve 11, and a silicone suction cup 13 is fixedly installed at the bottom of the telescopic tube 12, an upper needle seat 14 and a lower needle seat 15 are fixedly installed inside the telescopic tube 12, a top pin 16 is slidably connected between the upper needle seat 14 and the lower needle seat 15, a connecting hose 17 is fixedly connected to the top of the telescopic tube 12, and the top of the connecting hose 17 is connected to the inside of the air pressure connecting chamber 701.

[0033] The working principle of this clamp when clamping refractory bricks is:

[0034] First, the robot arm 1 drives the clamp 2 to move above the target refractory brick, and makes the shell 7 fit on the surface of the top of the target refractory brick. At this time, the silicone suction cups 13 and the telescopic tubes 12 of the several air pressure switching mechanisms 10 freely expand and contract according to the shape of the top surface of the refractory brick and fit on the top surface of the refractory brick. At the moment when the silicone suction cup 13 fits the top surface of the refractory brick, the corresponding ejector pin 16 is retracted into the inside of the telescopic tube 12 under the influence of the downward pressure. At this time, the negative pressure suction pipe 4 inhales air through the connection of the three-way solenoid valve 3 to the connecting hose 6, and is connected to the air pressure The connection of chamber 701 inhales air to several connecting hoses 17, and then the connecting hose 17 inhales air to the inside of the telescopic tube 12 through the through hole at the top of the inner wall of the telescopic tube 12, and inhales air to the inside of the silicone suction cup 13 through the air hole 1401 and the connecting channel 1602, so that the silicone suction cup 13 is firmly adsorbed on the surface of the refractory brick, which is convenient for the transfer of the target refractory brick driven by the robot arm 1 and the clamp 2. When the target refractory brick reaches the specified position, the negative pressure suction pipe 4 stops inhaling air, and the ejector pin 16 is reset at this time, thereby achieving the process of putting down the refractory brick;

[0035] The working principle of soot blowing inside this fixture is:

[0036] Based on the above, during the process of adsorbing and clamping refractory bricks, the dust on the surface enters the telescopic tube 12 through the connecting channel 1602 and is blocked by the filter 20. At this time, the air inside the positive pressure blowing pipe 5 enters the connecting hose 1 6 through the connection of the three-way solenoid valve 3, and enters each connecting hose 2 17 through the air pressure connecting chamber 701, and blows air to the filter 20 at the bottom of the connecting hose 2 17. At this time, the dust enters the T-shaped channel 1601 and is then discharged through the two exhaust channels 1501 to avoid dust accumulation at the filter 20.

[0037] Embodiment 2:

[0038] In view of the above embodiment 1, for further description, refer to Figure 3-Figure 5 A limiting groove for sliding connection with the outer edge of the top of the telescopic tube 12 is provided on the inner wall of the sleeve 11, and a support spring 18 is sleeved inside the limiting groove.

Connecting channels 1602 are also provided on both sides of the outer wall of the ejector pin 16, and the two connecting channels 1602 are staggered between the two exhaust channels 1501.

[0039] Support spring 1 18 and support spring 2 19 can respectively support and reset the telescopic tube 12 and the ejector pin 16. The filter screen 20 serves to block the gas and dust from entering the connecting hose 2 17. The two connecting channels 1602 are staggered between the two exhaust channels 1501 to avoid interference during gas exchange.
