Description

Technical Field

[0001] The invention relates to the technical field of metal sheet handling, and in particular to a metal sheet handling device. Background Art

[0002] Various metal plates are needed in the process of sheet metal manufacturing, and most of the metal plates are stored in stacks. In order to prevent surface corrosion of some metal plates, chemical treatment is usually used to cover the surface of the metal plates with a protective film, namely, an oil film. This oil film is usually formed by a specific lubricating oil or anti-rust oil, which aims to protect the surface of the metal plate from erosion by the external environment.

[0003] At present, when transporting these metal sheets, transport robots are usually used. These robots fix the metal sheets through suction cups, but the oil film on these metal sheets will reduce the adsorption force of the suction cups on the metal sheets, which may cause the metal sheets to fall off or slide due to insufficient adsorption force during the transport process. In order to solve the above problems, the present invention provides a metal sheet transporting device. Summary of the invention

[0004] In view of the above-mentioned technical deficiencies, the object of the present invention is to provide a metal sheet handling device, which supports the metal sheet from below through the setting of support rods. At the same time, the support rods can clean the oil film on the metal sheet, thereby avoiding the oil film from affecting the adsorption force of the suction cup.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a metal sheet handling device, comprising:

[0006] A frame, wherein the frame is interconnected with an external driving device;

[0007] A plurality of vacuum suction cups, wherein the plurality of vacuum suction cups are mounted on the frame and are interconnected with an external air pump;

[0008] Two support rods, which are symmetrically mounted on the frame and move away from or towards each other along the long side of the frame, and the height of the support rods is lower than the height of the vacuum suction cup;

[0009] Wherein, the sides of the two support rods facing each other are wedge-shaped, and scraping grooves are provided on the inclined surfaces on both sides of the wedge.

[0010] Preferably, a cavity is provided inside the support rod, and the cavity is communicated with two scraping grooves respectively, and the groove wall of the scraping groove protrudes from the inner wall of the cavity.

[0011] Preferably, a spring sheet is installed at the notch of the scraper groove, and one end of the spring sheet close to the wedge-shaped tip of the support rod is fixedly connected to the groove wall of the scraper groove, and the other end away from the wedge-shaped tip of the support rod fits with the corresponding groove wall of the scraper groove under the action of its own elastic force.

[0012] Preferably, a discharge pipe is fixedly connected to a side surface of the support rod away from the wedge-shaped tip, and a sealing plug is installed inside the discharge pipe.

[0013] Preferably, the inner side wall of the cavity away from the scraping groove is an inclined surface, and the distance between the end of the inclined surface close to the discharge pipe and the scraping groove is greater than the distance between the rest of the inclined surface and the scraping groove.

[0014] Preferably, a plurality of support blocks are fixedly connected between the two side walls inside the cavity.

[0015] Preferably, the framework comprises:

[0016] A center rod, wherein the center rod is connected to external equipment via a flange fixedly connected thereto;

[0021] The beneficial effects of the present invention are:

[0022] The present invention is provided with two support rods, both of which are located below the suction cup, and both of which are hollow structures. When transporting metal sheets, the metal sheets can be adsorbed by the suction cup.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention provides a metal sheet handling device, such as Figures 1 to 5 shown.

[0034] Embodiment 1:

[0035] A metal sheet handling device includes a frame 1, which includes a center rod 101 and four branch rods 102. A flange is fixedly connected in the middle of the center rod 101, and the flange can be connected to external equipment through bolts (the external equipment can be a handling robot arm, an industrial robot). The four branch rods 102 are distributed in pairs at both ends of the center rod 101, that is, two branch rods 102 are fixedly connected to both ends of the center rod 101, and the branch rods 102 located at both ends of the center rod 101 are symmetrical to each other, and the branch rods 102 are fixedly connected to the center rod 101.

[0036] A vacuum suction cup 2 is installed at the lower end of each branch rod 102, and the vacuum suction cup 2 is connected to an external air pump. By controlling the start and stop of the air pump, it is possible to control whether the vacuum suction cup 2 performs adsorption work.

[0037] Support rods 3 are installed at both ends of the center rod 101, and the two support rods 3 move away from or towards each other along the long side of the center rod 101, that is, the two support rods 3 can move toward the center position of the center rod 101 at the same time, or move away from the center of the center rod 101 at the same time. The two sides of the two support rods 3 facing each other are wedge-shaped, and the height of the support rods 3 is lower than the height of the vacuum suction cup 2, that is, when the vacuum suction cup 2 adsorbs the metal sheet, the wedge-shaped tip on the support rod 3 is at the same height as the lower side of the metal sheet adsorbed by the vacuum suction cup 2, and scraping grooves 4 are provided on the inclined surfaces on both sides of the wedge-shaped end of the support rod 3.

[0038] When in use, the vacuum suction cup 2 needs to adsorb the metal sheet, and then the two support rods 3 are moved toward the center direction of the center rod 101 at the same time, so that the two support rods 3 can enter under the metal sheet to provide support. In the process of the two support rods 3 moving toward each other, the scraping groove 4 can scrape off the oil film on the metal sheet on the movement trajectory of the support rods 3. In the process of movement, the support rods 3 can clean the oil film on the metal sheets on the upper and lower sides thereof, so that the vacuum suction cup 2 can stably adsorb the next metal sheet (because the oil film at the contact position between the metal sheet and the vacuum suction cup 2 is cleaned by the support rods 3). When using the present invention to transport stacked metal sheets, it is only necessary to clean the oil film on the side surface of the top metal sheet.

[0039] Furthermore, when the support rod 3 is inserted between the two metal plates, the two metal plates will be forced to overcome the adhesion of the oil film and separate from each other, thereby further facilitating the transportation of the metal plates.

[0040] Both ends of the support rod 3 are fixedly connected with a connecting rod 11, and the two connecting rods 11 are respectively threadedly connected to the bidirectional screws 12 installed on both sides of the frame 1. The connecting rod 11 located at both ends of one support rod 3 is threadedly connected to one end of the bidirectional screw 12, and the connecting rod 11 located at both ends of the other support rod 3 is threadedly connected to the other end of the bidirectional screw 12. The thread directions of the two ends of the bidirectional screw 12 are opposite, that is, when the bidirectional screw 12 rotates, the two support rods 3 can be moved toward or away from each other at the same time through the connecting rod 11. The bidirectional screw 12 is rotatably installed between the two branch rods 102 on the same side, and is driven by a rotary cylinder 13 installed on the corresponding branch rod 102. The rotary cylinder 13 is connected to an external air pump. The air pump can control whether the rotary cylinder 13 drives the bidirectional screw 12 to rotate and the rotation direction of the rotary cylinder 13.

[0041] Embodiment 2:

[0042] On the basis of the first embodiment, in order to prevent the oil scraped by the scraping groove 4 from flowing back onto the metal plate and affecting the next handling work, a cavity 5 is set inside the support rod 3, and the cavity 5 is respectively communicated with the two corresponding scraping grooves 4, and the groove wall of the scraping groove 4 protrudes from the side wall of the cavity 5, so that the scraped oil can be retained inside the cavity 5 to prevent the oil from flowing back onto the metal plate.

[0043] Furthermore, a spring piece 6 is installed at the groove of the scraper groove 4, and one end of the spring piece 6 close to the wedge-shaped tip of the support rod 3 is fixedly connected to the groove wall of the scraper groove 4, and the end away from the wedge-shaped tip of the support rod 3 fits with the groove wall of the scraper groove 4 as a floating end under the action of its own elastic force. Due to the shape and installation position of the spring piece 6, its floating end can only bend inward (i.e., inside the scraper groove 4), and cannot bend toward the outside of the scraper groove 4, so that the spring piece 6 can form a one-way valve, so that the oil can push open the spring piece 6 and enter the interior of the scraper groove 4, but cannot flow out from the interior of the scraper groove 4.

[0044] In order to facilitate pouring out the oil accumulated in the cavity 5, a discharge pipe 7 is fixedly connected to the side surface of the support rod 3 away from the wedge-shaped tip, the discharge pipe 7 is communicated with the cavity 5, and a sealing plug is installed inside the discharge pipe 7 to prevent the oil in the cavity 5 from being discharged through the discharge pipe 7 at will, and the inner side wall of the side where the cavity 5 is communicated with the discharge pipe 7 is set as an inclined surface, and the distance between the end of the inclined surface close to the discharge pipe 7 and the scraping groove 4 is greater than the distance between the rest of the inclined surface and the scraping groove 4. When pouring out the oil in the cavity 5, the sealing plug is taken out from the inside of the discharge pipe 7, and the opening of the discharge pipe 7 is facing downward. At this time, the oil in the cavity 5 will slide toward the direction of the discharge pipe 7 under the action of its own gravity, so that it can be completely discharged from the inside of the cavity 5.

[0045] In order to improve the supporting force of the support rod 3, a plurality of support blocks 10 are arranged inside the cavity 5, and the support blocks 10 are located between the two side walls of the cavity 5, so that the support rod 3 can support and hold up the metal plate more stably.

[0046] Embodiment three:

[0047] On the basis of the second embodiment, in order to enable the present invention to transport metal plates more stably, a plurality of telescopic rods 8 are fixedly installed on the side surface opposite to each other of the two support rods 3, and the end of the telescopic rod 8 away from the support rod 3 is fixedly connected to the corresponding limit rod 9, and the limit rod 9 is fixedly connected to the corresponding branch rod 102. When the two support rods 3 move toward each other, the telescopic rod 8 will extend, and when the two support rods 3 move away from each other, the telescopic rod 8 will retract.

[0048] The plurality of limiting rods 9 and the four connecting rods 11 can cooperate with each other to limit the metal plate from four sides of the metal plate to prevent the metal plate from slipping during transportation.

[0049] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
