Description

Technical Field

[0001] This utility model relates to the field of gripping technology, and in particular to a plate gripping device for laser straight seam welding. Background Technology

[0002] Electric kettles are a common household item, popular for their convenient heating and reliable safety. The inner liner of an electric kettle is its core component, and its manufacturing quality directly affects subsequent assembly and use.

[0003] Traditionally, the inner liner of an electric kettle is made by placing sheet metal into a splicing device using a gripping device, then welding the spliced ​​sheet metal together using a laser welding device.

[0004] However, when the boards are gripped by the gripping equipment, the boards are often tightly attached to each other, causing one board to pick up another board while being gripped. This results in both boards entering the splicing equipment at the same time, leading to splicing failure. Furthermore, it often happens that when one board picks up another board while being gripped, the other board falls off midway, affecting the normal operation of the rest of the equipment.

Detailed Implementation

[0029] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Please refer to Figures 1 to 6 As shown, a plate gripping device for laser straight seam welding according to the present invention includes a machine base 1, a splicing equipment body 2, a moving mechanism and a plate gripping mechanism. The splicing equipment body 2 is provided on one side of the lower part of the machine base 1, and a material trough is provided on the other side of the lower part of the machine base 1. The moving mechanism is connected to the upper part of the machine base 1 and is drivenly connected to the plate gripping mechanism.

[0031] The sheet material gripping mechanism includes a first linear drive component 9, a lifting plate 11, a vacuum exhaust component 10, suction cups 12, and a shaking material dropping mechanism 3. The upper part of the first linear drive component 9 is connected to the moving mechanism, and the lower part of the first linear drive component 9 is linearly driven connected to the lifting plate 11. The vacuum exhaust component 10 is installed on the upper surface of the lifting plate 11, and a plurality of suction cups 12 are installed on the lower surface of the lifting plate 11. Each suction cup 12 is connected to the vacuum exhaust component 10 through an air guide pipe. A shaking material dropping mechanism 3 is provided on both sides of the lifting plate 11.

[0032] The working principle of this utility model is as follows: In the actual processing of the inner liner of an electric kettle, the inner liner plate can be placed in the material tank. Then, the first linear drive 9 is moved by the moving mechanism. After the lifting plate 11 reaches above the plate, the first linear drive 9 is activated, causing the lifting plate 11 to descend and the suction cup 12 to contact the plate. At the same time, the vacuum exhaust device 10 is activated, causing the vacuum exhaust device 10 to exhaust the air in the suction cup 12 through the air guide pipe and adsorb the plate through the suction cup 12. Then, the first linear drive 9 is activated to drive the plate to rise. At the same time, the shaking and dropping mechanism 3 is activated, causing the shaking and dropping mechanism 3 to vibrate the plate and separate the adsorbed plate. Then, the moving mechanism is activated, causing the plate to enter the splicing equipment body 2.

[0033] Furthermore, the vibrating material feeding mechanism 3 includes a mounting frame 301, a mounting sleeve 302, a first rotating drive component 305, a movable shell 303, a rotating disk 306, a sliding disk 308, a tension spring 307, and a vibrating hammer 304. One side of the mounting frame 301 is fixedly connected to the lifting plate 11, and the other side of the mounting frame 301 is fixedly connected to the mounting sleeve 302. The first rotating drive component 305 is installed inside the mounting sleeve 302. The bottom of the mounting sleeve 302 is fixedly connected to the movable shell 303, and the upper part of the movable shell 303 can... The rotating disk 306 is rotatably connected to the rotating disk 306, and the sliding disk 308 is slidably connected to the lower part of the movable shell 303. The rotating disk 306 is connected to the sliding disk 308 via the tension spring 307. A first protrusion 310 is provided on the side of the rotating disk 306 near the sliding disk 308. The first rotation drive member 305 is rotatably driven connected to the other side of the rotating disk 306. A second protrusion 309 is provided on the side of the sliding disk 308 near the rotating disk 306. The shaking hammer 304 is provided on the other side of the sliding disk 308.

[0034] As can be seen from the above description, when it is necessary to vibrate the plate, the first rotation drive 305 can be operated, so that the first rotation drive 305 drives the rotating disk 306 to rotate within the movable shell 303. At the same time, the sliding disk 308 moves upward under the action of the tension spring 307. When the rotating disk 306 rotates, the first protrusion 310 squeezes the second protrusion 309, so that the second protrusion 309 drives the sliding disk 308 to move downward. After the sliding disk 308 has moved downward, it returns to its original position under the action of the tension spring 307. At the same time, the sliding disk 308 drives the shaking hammer 304 to shake up and down, and the shaking hammer 304 vibrates the plate, so that the adsorbed plate separates.

[0035] Furthermore, the outer surface of the sliding disk 308 is provided with a limiting slider 311, and the inner surface of the movable shell 303 is provided with a limiting groove adapted to the limiting slider 311. The sliding disk 308 is slidably connected to the limiting groove through the limiting slider 311. The limiting slider 311 and the limiting groove are used to limit the sliding direction of the sliding disk 308.

[0036] As can be seen from the above description, it is beneficial to limit the sliding disk 308 to only slide up and down by using the limit slider 311, thereby preventing the sliding disk 308 from rotating.

[0037] Furthermore, the vibrating hammer 304 is made of a flexible material.

[0038] As can be seen from the above description, it helps to avoid damage to the plate caused by the shaking hammer 304.

[0039] Furthermore, it also includes a material limiting plate 13, which is provided on the outer side of the material trough.

[0040] As can be seen from the above description, it is beneficial to restrict the position of the material by means of the material limiting plate 13, so as to avoid easy grabbing.

[0041] Furthermore, the moving mechanism includes a linear motor 4, a mover, and a height adjustment mechanism. The linear motor 4 is mounted on the upper part of the machine base 1 and is linearly driven connected to the mover. The plate gripping mechanism is connected to the mover through the height adjustment mechanism.

[0042] As can be seen from the above description, the linear motor 4 can drive the plate gripping mechanism to move through the mover and the height adjustment mechanism, and at the same time, the height of the plate gripping mechanism can be finely adjusted through the height adjustment mechanism.

[0043] Furthermore, the height adjustment mechanism includes a movable platform 7, a second rotation drive 6, a screw, and a lifting rod 5. The movable platform 7 is fixedly connected to the moving element. The movable platform 7 is provided with a lifting groove, and the screw is rotatably connected in the lifting groove. The second rotation drive 6 is drivenly connected to the screw. One side of the lifting rod 5 is threadedly connected to the screw, and the other side of the lifting rod 5 is connected to the first linear drive 9.

[0044] As can be seen from the above description, when it is necessary to fine-tune the height of the sheet metal gripping mechanism, the second rotation drive 6 can be operated to drive the screw to rotate, and the screw will drive the lifting rod 5 to slide in the lifting groove. At the same time, the height of the sheet metal gripping mechanism can be finely adjusted through the lifting rod 5.

[0045] Furthermore, it also includes a support frame 8, one side of the linear motor 4 is connected to the upper part of the machine base 1, and the other side of the linear motor 4 is connected to the upper part of the machine base 1 through the support frame 8.

[0046] As can be seen from the above description, it is advantageous to support the other side of the linear motor 4 through the support frame 8.

[0047] Furthermore, it also includes a controller, which is electrically connected to both the moving mechanism and the plate gripping mechanism.

[0048] As can be seen from the above description, it makes it more convenient for users to control the overall device. Example 1
