Description

Technical Field

[0001] This utility model relates to the field of auxiliary feeding technology, specifically an auxiliary feeding device for sheet metal processing. Background Technology

[0002] Sheet metal refers to thin sheets or plates made of metal materials (usually steel, aluminum, copper, etc.), and is widely used in various fields such as machinery manufacturing, automotive industry, construction, home appliances, and aerospace. Sheet metal processing refers to the cutting, bending, welding, stamping, and other processes of metal sheets to produce final products or parts. Auxiliary feeding devices are equipment used to automatically or semi-automatically transport raw materials or parts to workstations during the production process. They play an important role in improving production efficiency, reducing manual intervention, and improving work safety. Auxiliary feeding devices for sheet metal processing are equipment used to automate the processing of sheet metal materials, aiming to improve production efficiency, reduce manual intervention, and improve safety and accuracy.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN215207175U) discloses an auxiliary feeding device for sheet metal processing. The device includes a machine body, a first conveyor belt on the left side of the machine body, and an adjustment device fixedly connected to the top of the machine body. A separation device extending to the left side of the adjustment device is fixedly connected to the top of the adjustment device. A second conveyor belt, identical to the first conveyor belt and located above it, is fixedly connected to both the front and rear sides of the first conveyor belt. This auxiliary feeding device for sheet metal processing offers advantages such as good layering effect, solving the problem that existing sheet metal processing requires manual layering of stacked sheets before processing. However, the edges of sheet metal sheets often have many sharp burrs, which can easily lead to safety accidents. Furthermore, long-term stacking can cause the gaps between the sheets to become tightly adhered, making separation difficult.

[0004] While the aforementioned patent addresses the issue of manually separating stacked sheet metal before processing by using a layering device, the edges of sheet metal often have sharp burrs, posing a safety hazard. Furthermore, prolonged stacking can cause the gaps between sheets to become tightly fitted, making separation difficult. However, when using rubber to grip and load sheet metal, the rubber's adsorption effect is poor. With repeated adsorption, dust adheres to the rubber surface, reducing its adsorption capacity. This can lead to loosening and gaps during sheet metal loading, causing the sheet metal to fall directly, posing a danger and damaging the sheet metal, thus affecting its normal use. Therefore, the adsorption effect during gripping and loading is inadequate.

[0005] Therefore, this utility model provides an auxiliary feeding device for sheet metal processing to solve the above problems. Utility Model Content

[0009] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary feeding device for sheet metal processing, including a feeding robotic arm, an adsorption plate fixedly installed at one end of the feeding robotic arm, A telescopic tubes fixedly connected to both sides of the adsorption plate, an extension adsorption plate fixedly connected to one end of the A telescopic tubes, and an air extraction hole opened at the bottom of both the adsorption plate and the extension adsorption plate, with a dispensing mechanism fixedly connected inside the air extraction hole.

[0015] As a preferred technical solution of this application, a transmission pipe is fixedly connected to the middle of both sides of the adsorption plate, and the transmission pipe is made of flexible tubing.

[0016] (III) Beneficial Effects

[0017] This invention features a simple structure and convenient operation. In sheet metal processing, the sheet metal material to be processed needs to be gripped onto the processing equipment. However, the adsorption strength is poor during gripping and loading, and dust easily accumulates with repeated gripping. Loosening can easily occur during gripping, causing the sheet metal to fall, posing a danger and damaging the sheet metal, affecting its normal use. By utilizing a vacuum pump and suction cups, a vacuum adsorption effect can be achieved. The length of the extended adsorption plate is adjusted according to the shape and length of the sheet metal, adsorbing both ends and the middle of the sheet metal. During adsorption, the angle of the suction cups can be adjusted according to the shape, resulting in a tighter and more stable contact between the suction cups and the sheet metal surface. This stable contact reduces material movement during handling, lowering the risk of falling or slipping. Vacuum adsorption can quickly generate adsorption force, shortening gripping and placement time, and improving work efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides an auxiliary feeding device for sheet metal processing, such as... Figures 1-4As shown, the auxiliary feeding device for sheet metal processing includes a feeding robotic arm 1. An adsorption plate 2 is fixedly installed at one end of the feeding robotic arm 1. A telescopic tube 3 is fixedly connected to both sides of the adsorption plate 2. An extension adsorption plate 4 is fixedly connected to one end of the telescopic tube 3. An air extraction hole is opened at the bottom of both the adsorption plate 2 and the extension adsorption plate 4. An adjustment mechanism is fixedly connected inside the air extraction hole.

[0026] The dispensing mechanism includes an air extraction pipe 5, one end of which is fixedly connected to the inside of an air extraction hole. A gasket 6 is fixedly connected to the outer surface of the air extraction pipe 5, a spring 7 is fixedly connected to the upper surface of the gasket 6, and a rotating component 8 is fixedly connected to the bottom of the gasket 6. During sheet metal processing, the sheet metal material to be processed needs to be gripped on the processing equipment. However, the adsorption strength is not good when gripping and loading. Dust easily accumulates when gripping more times. Loosening is easy to occur during the gripping process, causing the sheet metal to fall off, which is dangerous and can damage the sheet metal, affecting its normal use. Vacuum suction pump 14 and suction cup 13 can achieve the effect of vacuum adsorption. The length of the extension adsorption plate 4 is adjusted according to the shape and length of the sheet metal to adsorb the two ends and the middle of the sheet metal. During adsorption, the angle of the suction cup 13 can be adjusted according to its shape, so that the suction cup 13 and the sheet metal surface are in closer contact. Stable contact reduces the movement of the material during the handling process and reduces the risk of falling off or sliding. Vacuum adsorption can quickly generate adsorption force, shorten the gripping and placement time, and improve work efficiency.

[0027] One end of rotating component A 8 is fixedly connected to spring B 9, one end of spring B 9 is fixedly connected to rotating component B 10, one end of rotating component B 10 is fixedly connected to gasket B 11, the other end of suction pipe 5 is fixedly connected to telescopic tube B 12, one end of telescopic tube B 12 is fixedly connected to suction cup 13. When suction cup 13 is brought into contact with the upper surface of sheet metal, suction cup 13 is squeezed according to the shape of sheet metal. Suction cup 13 squeezes rotating component B 10, rotating component B 10 squeezes spring B 9 and rotating component A 8, which facilitates left and right adjustment. Rotating component A 8 is squeezed onto the surface of suction plate 2 or extended suction plate 4 through gasket A 6 and spring A 7, thereby achieving the effect of adjusting the angle of suction cup 13 and making suction cup 13 in close contact with sheet metal.

[0028] A vacuum pump 14 is fixedly connected to the middle of the upper surface of the adsorption plate 2. An electric push rod 15 is fixedly connected to one side of the upper surface of the adsorption plate 2 via bracket A. One end of the electric push rod 15 is fixedly connected to the upper surface of the extended adsorption plate 4. The electric push rod 15 is activated according to the length of the sheet metal. The electric push rod 15 drives the extended adsorption plate 4 to extend and retract. During the adjustment, the A telescopic tube 3 and the transmission tube 20 extend and retract together.

[0029] On the other side of the upper surface of the adsorption plate 2, a sleeve 16 is fixedly connected via bracket B. A compression spring 17 is fixedly connected inside the sleeve 16. A telescopic rod 18 is fixedly connected to one end of the compression spring 17. When the electric push rod 15 extends or retracts, it drives the telescopic rod 18 to extend or retract within the sleeve 16, which plays an auxiliary role in extension and retraction and helps to maintain the balance of the extended adsorption plate 4. The telescopic rod 18 squeezes the compression spring 17, which plays a buffering role and prevents the large extension and retraction range from causing vibration and affecting the gripping of sheet metal.

[0030] A sealing ring 19 is fixedly connected at the interface between the suction pipe 5 and the suction port. The sealing ring 19 is made of rubber. During vacuum adsorption, in order to prevent air leakage at the interface between the suction port and the suction pipe 5 and affect the adsorption effect, the sealing ring 19 is used to enhance the adsorption effect.

[0031] A transmission pipe 20 is fixedly connected to the middle of both sides of the adsorption plate 2. The transmission pipe 20 is made of flexible tubing. The transmission pipe 20 draws air from the vacuum pump 14 to achieve the effect of gas transmission, which facilitates the adsorption and loading of sheet metal.

[0032] Specifically, during sheet metal processing, the loading robotic arm 1 moves the suction plate 2 according to the location of the sheet metal, placing it above the sheet metal. Based on the length of the sheet metal, the electric push rod 15 is activated, causing the extension suction plate 4 to extend and retract. During adjustment, the A telescopic tube 3 and the transmission tube 20 extend and retract together. Subsequently, as the electric push rod 15 extends and retracts, it drives the telescopic rod 18 to extend and retract within the sleeve 16, providing auxiliary extension and retraction to maintain the balance of the extension suction plate 4. The telescopic rod 18 compresses the compression spring 17, providing a buffering effect to prevent excessive extension and retraction from causing vibration and affecting the gripping of the sheet metal. Then, the suction cup 13 contacts the upper surface of the sheet metal, and the suction cup 13 is pressed according to the shape of the sheet metal. The suction cup 13 presses against the B rotating component 10, and the B rotating component 10 presses against the B rotating component 10. Spring 9 and rotating component A 8 facilitate left and right adjustment. Rotating component A 8 is pressed against the surface of adsorption plate 2 or extended adsorption plate 4 by pad A 6 and spring A 7, thereby adjusting the angle of suction cup 13 and ensuring tight contact between suction cup 13 and sheet metal. Vacuum pump 14 is then activated, drawing air through transmission pipe 20 into the air extraction hole and then through air extraction pipe 5, achieving vacuum adsorption of the sheet metal. To prevent air leakage at the interface between the air extraction hole and air extraction pipe 5 during vacuum adsorption, which would affect the adsorption effect, sealing ring 19 is used to enhance the adsorption effect. Stable contact reduces material movement during handling, lowers the risk of falling or sliding, and enhances the firmness of gripping and loading. Vacuum adsorption can quickly generate adsorption force, shortening the gripping and placement time and improving work efficiency.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
