Description

Technical Field

[0001] The utility model relates to the technical field of silicon steel sheet suction cup equipment, and particularly relates to an improved silicon steel sheet suction cup. Background Art

[0002] A silicon steel sheet suction cup is a special tool for handling and fixing silicon steel sheets, usually used in the production and processing of transformers, motors and generators. Silicon steel sheets are high-permeability steel materials used to manufacture iron core materials, and are widely used in equipment such as power transformers and motors. Since the silicon steel sheets are thin and have a smooth surface, it is difficult for traditional mechanical clamps to effectively grasp and fix them. At this time, the silicon steel sheet suction cup plays a role.

[0003] Most of the existing silicon steel sheet suction cups grab silicon steel sheets through electromagnetic suction cups. However, the working surface of the electromagnetic suction cup is usually made of metal. If the surface of the suction cup is not flat enough or has hard particles, scratches or indentations may be generated on the surface of the silicon steel sheet during adsorption. In addition, long-term power-on will cause the electromagnetic suction cup itself to heat up. If the adsorption time is too long or the heat dissipation is poor, the temperature rise of the suction cup may be transmitted to the silicon steel sheet, resulting in its thermal deformation or performance change. Therefore, it is necessary to develop a suction cup that can effectively protect silicon steel sheets. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an improved silicon steel sheet suction cup, which solves the problem of insufficient protection of traditional silicon steel sheet suction cups for silicon steel sheets.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the present utility model specification.

[0021] Embodiment:

[0022] As Figures 1-3As shown in the figure, an improved silicon steel sheet suction cup in this embodiment includes a bracket 1, which is composed of a circular plate and six straight plates. The six straight plates are scattered on the side of the circular plate, and the circular plate and the straight plates are integrally connected; three electromagnetic suction cups 3 and three vacuum suction cups 2. The vacuum suction cup 2 adsorbs objects through negative pressure and will not cause scratches or deformation to the surface of the workpiece. The three electromagnetic suction cups 3 and the three vacuum suction cups 2 are circumferentially distributed at the lower part of the bracket 1, and the electromagnetic suction cups 3 and the vacuum suction cups 2 are distributed at intervals. The bottom surface of the vacuum suction cup 2 is lower than the bottom surface of the electromagnetic suction cup 3 to prevent the silicon steel sheet from directly contacting the electromagnetic suction cup 3. When grasping the silicon steel sheet, the vacuum suction cup 2 is made to fit with the silicon steel sheet, and then the vacuum suction cup 2 is started. The air pressure inside the vacuum suction cup 2 decreases, and under the action of the atmospheric pressure, the silicon steel sheet fits tightly with the vacuum suction cup 2. Then the electromagnetic suction cup 3 is started, and under the action of the electromagnetic force, the force between the silicon steel sheet and the vacuum suction cup 2 is enhanced again, so that the silicon steel sheet is firmly fixed on the device; by setting the combined action of the electromagnetic suction cup 3 and the vacuum suction cup 2, it not only combines the advantage that the vacuum suction cup 2 can effectively protect the silicon steel sheet, but also combines the strong attraction of the electromagnetic suction cup 3, and under the dual action of the atmospheric pressure and the electromagnetic attraction, the silicon steel sheet is firmly fixed on the device without being damaged; by setting multiple electromagnetic suction cups 3 and vacuum suction cups 2, the device contacts the silicon steel sheet at multiple points, increasing the contact area between the device and the silicon steel sheet and further enhancing the fixing force of the device.

[0023] A vacuum machine 5 is provided at the upper part of the bracket 1. The output end of the vacuum machine 5 is provided with a vacuum tube 4, and the other end of the vacuum tube 4 is connected to the vacuum suction cup 2.

[0024] A laser locator 8 is provided at the center of the bottom surface of the bracket 1. A suspension bracket 6 is provided at the upper part of the bracket 1, and a hook 7 is provided at the upper part of the suspension bracket 6.

[0025] Working principle

[0026] When hoisting the silicon steel sheet, start the laser locator 8 and make the laser emitted by the laser locator 8 coincide with the center of the silicon steel sheet. Then make the vacuum suction cup 2 fit with the silicon steel sheet, start the vacuum machine 5, and under the attraction of the vacuum machine 5, the air pressure inside the vacuum suction cup 2 decreases. Under the action of the atmospheric pressure, the silicon steel sheet fits tightly with the vacuum suction cup 2 to complete the preliminary fixation of the silicon steel sheet. Then start the electromagnetic suction cup 3, and under the action of the electromagnetic force, the force between the silicon steel sheet and the vacuum suction cup 2 is enhanced again, so that the silicon steel sheet is firmly fixed on the device. Finally, the silicon steel sheet is moved to the destination through a hoisting device to complete the hoisting of the silicon steel sheet.
