Description

Technical Field

[0001] The present invention relates to the technical field of special-shaped metal plates, and more specifically, it relates to a device for collecting special-shaped metal plates. Background Art

[0002] Metal material plates are indispensable materials in fields such as printing and coating, mold making, and automobile manufacturing. Especially in automobile production, the white body needs to be composed of different metal material plates through welding, assembly, riveting, etc. In this process, metal plates with different shapes and structures will inevitably be encountered.

[0003] During the transmission of symmetric special-shaped metal plates, the operation of turning the plate often needs to be carried out. Manual turning of the plate increases the labor cost and also burdens the staff; during the punching and falling process of the metal plate, it cannot be directly transported by a belt because it suddenly falls onto the belt, and the belt is always in a conveying state, which is extremely likely to cause the phenomenon of belt shoveling; there are differences in the lengths of the molds, requiring the conveying device to be able to telescopically adjust back and forth to meet the needs of different parts; there are differences in the heights of the molds. When the stamped parts fall, if no corresponding adjustment is made, the metal plate will be deformed and damaged due to the impact force generated by the fall, affecting the quality of the product.

[0042] As Figure 1 、 Figure 4 and Figure 5 shown, the rapid conveying mechanism 6 includes a transmission support 61. Magnetic conveying mechanisms 62 are respectively arranged at both ends of the top of the transmission support 61. Movement grooves 63 are formed on the ground under each magnetic conveying mechanism 62. A material receiving mechanism 7 is arranged in the movement groove 63.

[0043] As Figure 1 、 Figure 4 and Figure 5 shown, the magnetic conveying mechanism 62 includes five groups of electromagnets 621.

[0045] As Figure 1 、 Figure 4 and Figure 5 shown, the material receiving mechanism 7 includes a lifting table mechanism 71. A sixth motor 72 and a lead screw mechanism 73 are arranged at the bottom of the lifting table mechanism 71. The sixth motor 72 drives the lifting table mechanism 71 to slide in the movement groove 63 by means of the lead screw mechanism 73.

[0046] In this embodiment, the power of the first motor 26 is 0.55 kw, the power of the second motor 43 is 1.1 kw, the power of the third motor 55 is 1.1 kw, the power of the fourth motor 58 is 7.5 kw, the power of the fifth motor 623 is 3 kw, and the power of the sixth motor 72 is 20 kw. The first motor 26, the second motor 43, the fourth motor 58, and the fifth motor 623 can all be servo motors produced by Shenzhen Changda Automation Equipment Co., Ltd., and the sixth motor 72 can be a three-phase motor produced by Dongguan Yuxin Electromechanical Co., Ltd.

[0047] The power of the lifting cylinder 33 is 1.5 kw, and it can be a standard cylinder produced by Ningbo Fenghua Zhongzhi Pneumatic Co., Ltd.

[0048] The telescopic motor 641 can be an MAL type mini cylinder produced by Ningbo Fenghua Zhongzhi Pneumatic Co., Ltd., and the suction cup 642 can be a vacuum suction cup produced by Shanghai Feipa Technology Co., Ltd.

[0049] The lifting table mechanism 71 can be a THD type hydraulic lift produced by Wuxi Zhenmu Machinery Co., Ltd.

[0050] Working principle: The metal plate enters this device from the left with the help of a hook. The first motor 26 drives the first belt mechanism 25 to drive the four supporting plates 11 to extend or shorten an appropriate distance to ensure that the metal plate can completely fall on the supporting mechanism 1. The lifting cylinder 33 performs a rising operation or a falling operation to drive the left side of the sliding frame 21 to rise, and then drives the left side of the supporting plate 11 to rise to prevent the metal plate from being deformed by a large impact force when falling. Through the sliding and telescoping of the supporting plate 11 or the action of the lifting cylinder 33, or the combination of both, it is ensured that the right end of the metal plate crosses the limiting frame 23 and contacts the second belt mechanism 44 on the transition conveying mechanism 4. Driven by the second motor 43, the second belt mechanism 44 drives the metal plate into the transition conveying mechanism 4. During the whole process, because the second motor 43 is a servo motor, the conveying speed can be controlled.

[0051] When passing through the turning plate mechanism 5, if turning is required, the turning plate mechanism 5 is lowered in advance. Specifically, the fourth motor 58 is started to release the chain, and the turning frame 53 descends along the sliding groove 52 to ensure that the turning teeth 56 can exert force on the bottom of the metal plate, and the metal plate is turned by means of the rotating turning teeth 56. Then the third motor 55 is started to drive the turning rod 54 to rotate, and the turning teeth 56 drive the metal plate to turn. If turning is not required, the turning plate mechanism 5 is raised to a height that will not affect the conveyance of the metal plate, and it is directly brought into the fast conveying mechanism 6 by the second belt mechanism 44.

[0052] Enter the fast conveying mechanism 6. If it is single-row discharging, only one receiving mechanism 7 and the leftmost magnetic conveying mechanism 62 need to operate. However, in most cases, double-row discharging is required. The metal plate is adsorbed on the magnetic conveying mechanism 62 under the attraction of the electromagnet 621. At the same time, there is also a transmission belt of the third transmission mechanism between the electromagnet 621 and the metal plate. The metal plates are grouped in pairs. The first metal plate reaches the rightmost end, and the second metal plate is at the left end. In order to reduce unnecessary waiting time, the conveying speed of this mechanism is relatively fast, which helps to improve work efficiency. The fifth motor 623 drives the third transmission mechanism to move. At the same time, the lifting table mechanism 71 reaches directly below the metal plate under the cooperation of the sixth motor 72 and the lead screw mechanism 73. The lifting table mechanism 71 rises to avoid the influence of a large height difference on the quality of the metal plate as much as possible. The transmission belt drives the metal plate to move to directly above the top of the corresponding lifting table mechanism 71, and then the power is cut off. The metal plate loses the adsorption of the electromagnet 621 and falls onto the lifting table mechanism 71. The lifting table mechanism 71 slowly descends as the height of the metal plate stack increases. After reaching full load, it moves to the edge of the transmission bracket 61 under the cooperation of the sixth motor 72 and the lead screw mechanism 73 for loading. The metal plate on the right end is also operated based on the same principle. The suction cup 642 is used as a safeguard, adsorbing at the corner of the metal plate to ensure that the metal plate falls more smoothly. The suction cup mechanism 64 is not necessary and can be selected or not according to the actual situation.
