Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a suction and holding device for processing large sheet metal parts. Background Technology

[0002] Although existing vacuum-bonding equipment for sheet metal parts has been continuously innovated and developed to basically meet people's needs, there is still room for improvement.

[0003] For example, patent document CN222359752U discloses a metal sheet processing suction device, including a frame, a mounting frame, and an electromagnetic chuck. A suction cup assembly is mounted on the top of the frame, comprising a hydraulic cylinder, a mounting frame, and the electromagnetic chuck. The mounting frame is connected to the top of the frame via the hydraulic cylinder, and electromagnetic chucks are mounted on both ends of the mounting frame. A cleaning component is also mounted on the top of the mounting frame. The design of the cleaning component enables the device to perform cleaning, blowing away dust and impurities adhering to the upper surface of the metal sheet, thus achieving the purpose of cleaning the metal sheet and improving the practicality of the device.

[0004] The aforementioned sheet metal part suction and holding equipment, although it uses airflow to remove impurities from the sheet metal part surface and enhances the electromagnet's suction and holding ability, relies on a blower and flexible hose for airflow transmission. If the sheet metal part is transported over a long distance, the hose needs to be extended accordingly, increasing unnecessary costs. Furthermore, airflow cannot effectively remove sticky impurities from the sheet metal part surface. Therefore, a large sheet metal part suction and holding device is needed to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a suction and holding device for processing large sheet metal parts, so as to solve the problem mentioned in the background art that although the sheet metal suction and holding equipment uses airflow to remove impurities from the surface of the sheet metal parts and improves the suction and holding capacity of the electromagnet, the airflow is transmitted through a blower and a hose. Once the sheet metal parts are transported over a long distance, the hose also needs to be extended to accommodate the change, which increases unnecessary costs. In addition, the airflow cannot effectively remove sticky impurities from the surface of the sheet metal parts.

[0006] This utility model provides the following technical solution: a suction device for processing large sheet metal parts, including an electric suction mechanism. The electric suction mechanism includes a cylinder frame connected to an electric slider on a track frame, and the bottom end of the cylinder frame is provided with a plurality of electric suction heads for suctioning sheet metal parts. The plurality of electric suction heads are evenly distributed at the ends of the branch rods of the branch rods. It also includes a cleaning mechanism in the same number as the number of electric suction heads, the cleaning mechanism including a scraper hinged to the side branch rod of the electric suction head; The scraper has a pre-drilled hole for the electric suction head to pass through, and when the scraper is not under pressure, the bottom end is tilted towards the corresponding electric suction head.

[0007] To achieve the above technical solution, the scraper is tilted without being pressed, and the scraper continues to descend with the branch rod, so that the scraper with the changed angle can scrape the surface of the sheet metal. Compared with the existing technology, this device can also effectively remove sticky impurities, and the overall impurity removal effect is better, ensuring the stability of the electric suction head and the sheet metal magnetic attraction.

[0008] As a further improvement to this utility model, an I-shaped seat is connected to the extended end of the cylinder frame, and a through hole is provided at the midpoint of the branch rod, which is movably sleeved on the I-shaped seat for up and down movement.

[0009] The above technical solution allows the electric suction head to obtain a certain buffer space.

[0010] As a further improvement to this utility model, a spring is connected between the branch rod and the I-shaped seat to apply downward pressure to the branch rod.

[0011] The above technical solution enables the electric suction head to fit tightly against the sheet metal parts.

[0012] As a further improvement to this utility model, the scraping area of ​​the scraper is an arc-shaped blade head area.

[0013] The above technical solution improves the scraping ability at the point where the scraper contacts the sheet metal part.

[0014] As a further improvement to this utility model, a tension spring for keeping the scraper tilted is connected between the scraper and the branch rod.

[0015] The above technical solution improves the stability of the scraper.

[0016] As a further improvement to this utility model, the scraper and the pull spring are non-magnetic components.

[0017] The above technical solution avoids the electric suction head affecting the scraper and pull spring after being powered on.

[0018] The technical effects and advantages of this utility model are as follows: 1. This utility model uses a scraper that is not under pressure and is in an inclined position. The scraper continues to descend with the branch rod, so that the scraper with the changed angle can scrape the surface of the sheet metal part.

[0019] 2. Compared with the prior art, this device can effectively remove sticky impurities, resulting in better overall impurity removal and ensuring the stability of the electric suction head and sheet metal magnetic attraction. Attached Figure Description

[0026] Example: Referring to the accompanying drawings, this utility model provides a suction device for processing large sheet metal parts, including an electric suction mechanism 100. The electric suction mechanism 100 includes a cylinder frame 111 connected to an electric slider on a track frame 110. The bottom end of the cylinder frame 111 is provided with a plurality of electric suction heads 113 for suctioning sheet metal parts. The plurality of electric suction heads 113 are evenly distributed at the branch ends of the branch rod 112. The extended end of the cylinder frame 111 is connected to an I-shaped seat 114. The midpoint of the branch rod 112 is provided with a through hole and is movably sleeved on the I-shaped seat 114 for up and down movement. A spring is connected between the branch rod 112 and the I-shaped seat 114 to apply downward pressure to the branch rod 112. It also includes a cleaning mechanism 200 in the same number as the electric suction head 113, and the cleaning mechanism 200 includes a scraper 210 hinged to the outer branch rod 112 of the electric suction head 113; The scraper 210 has a through hole for the electric suction head 113 to pass through. When the scraper 210 is not under pressure, the bottom end is tilted towards the corresponding electric suction head 113. The area scraped by the scraper 210 is an arc-shaped blade area 211. A pull spring 212 is connected between the scraper 210 and the branch rod 112 to keep the scraper 210 tilted. The scraper 210 and the pull spring 212 are non-magnetic components.

[0027] When in use, the electric slider of the track frame 110 drives the cylinder frame 111 and the electric suction head 113 to move above the sheet metal part. The extension rod of the cylinder frame 111 descends, allowing the electric suction head 113 to gradually approach the sheet metal part. During this process, as the branch rod 112 gradually approaches the sheet metal part, the bottom of the scraper 210 tilts along the surface of the sheet metal part, and the reaction force of the pull spring 212 being squeezed scrapes the surface of the sheet metal part until the electric suction head 113 passes through the through hole of the scraper 210 and comes into contact with the sheet metal part. After the electric suction head 113 is attached to the sheet metal part, the electric suction head 113 is powered on to fix the sheet metal part in place, and its position is changed in conjunction with the movement of the electric slider.
