DETAILED DESCRIPTION
[0020] Example
[0021] See also Figure 1-4 , the utility model provides a technical solution:
[0022] A vibration screening device for electronic components, wherein a vibration plate 2 is fixedly connected to the surface of the vibration screening machine 1, and the vibration plate 2 is used to place electronic components. After a large number of disordered electronic components are placed on the surface of the vibration plate 2, the vibration screening machine 1 is turned on, and the vibration screening machine 1 drives the vibration plate 2 to vibrate, and further controls the electronic components placed on the surface of the vibration plate 2 to be arranged neatly under the action of vibration, so as to facilitate the subsequent rapid screening of electronic components. A screening slide 3 is fixedly connected to the surface of the vibration plate 2, and a screening mechanism 4 is fixedly connected to the surface of the screening slide 3. When the electronic components placed on the surface of the vibration plate 2 are arranged under the action of vibration, the electronic components will move to the surface of the screening slide 3 and move along the surface of the screening slide 3, so that a large number of electronic components are further arranged neatly and then pass through the screening mechanism 4, and the electronic components are further screened in sequence by the screening mechanism 4, thereby realizing the classification and screening of electronic components.
[0023] The surface of the screening slide rail 3 is provided with two groups of symmetrically distributed mounting grooves 6, and the screening mechanism 4 is installed at the two groups of mounting grooves 6. The screening mechanism 4 includes a fixed rod 401 connected to the lower end surface of the screening slide rail 3, and the fixed rod 401 is located below the two groups of mounting grooves 6. The surface of the fixed rod 401 is sleeved with two groups of sliding sleeves 402, and the surfaces of the two groups of sliding sleeves 402 are fixedly connected with vertical rods 403, and the surfaces of the vertical rods 403 are sleeved with limit blocks 404, and the two groups of limit blocks 404 are inserted in the two groups of mounting grooves 6 in an adaptive manner. By inserting the limit blocks 404 in the mounting grooves 6, the interior of the screening slide rail 3 can be blocked, and further the limit blocks 404 can limit the electronic components sliding inside the screening slide rail 3. The surface of the sliding sleeve 402 is provided with a threaded hole and a fixing bolt A405 is inserted into the threaded hole. The sliding sleeve 402 slides on the surface of the fixing rod 401 to adjust the spacing between the two sets of limit blocks 404, and the fixing bolt A405 is tightened in the threaded hole to achieve fixation. The two sets of limit blocks 404 can further form limit blocks of different widths inside the screening slide rail 3, and further screen electronic components of different widths inside the screening slide rail 3.
[0024] The limit block 404 can slide up and down on the surface of the vertical rod 403 to further adjust the height of the limit block 404 relative to the screening slide rail 3. At the same time, a threaded hole is provided on the surface of the limit block 404 and a fixing bolt B406 is inserted in the threaded hole. The limit block 404 can be fixed by tightening the fixing bolt B406 in the threaded hole. The limit block 404 can limit the electronic components of different thicknesses sliding on the surface of the screening slide rail 3.
[0025] The surface of the limit block 404 is fixedly connected with a fixed block 407, and a hinge shaft 408 is inserted on the surface of the fixed block 407. A buffer plate 409 is hinged on the surface of the hinge shaft 408, and the buffer plate 409 faces the side of the vibration plate 2. At the same time, a slot 5 is provided on the side of the screening slide rail 3, and one end of the buffer plate 409 passes through the slot 5. The surface of the limit block 404 is fixedly connected with a limit rod 410, which is located on one side of the slot 5 and is distributed in parallel. The end of the limit rod 410 away from the limit block 404 is fixedly connected to the limit plate 411, and the surface of the buffer plate 409 is provided with a slot 412, and the limit rod 410 is inserted in the slot 412 in a matching manner. At the same time, the surface of the limit rod 410 is sleeved with a push block 413 and a spring A414, one end of the spring A414 is connected to the surface of the push block 413, and the other end of the spring A414 is connected to the surface of the limit block 404. After the position and height of the limit block 404 are adjusted inside the screening slide rail 3, the height of the buffer plate 409 will be adjusted synchronously through the fixed block 407 and the limit rod 410, and the electronic components sliding toward the side of the limit block 404 can be further buffered. When the electronic components slide toward the side of the limit block 404, they will first contact the surface of the buffer plate 409, and when the electronic components continue to be pushed toward the side of the limit block 404, the buffer plate 409 will be squeezed, and the buffer plate 409 will be further controlled to slide on the surface of the limit rod 410. During the sliding process, the buffer plate 409 will push the push block 413 to slide on the surface of the limit rod 410, and the push block 413 will be further controlled to squeeze the spring A414, and the sliding of the push block 413 will be buffered by the elastic force of the spring A414, and the compression of the buffer plate 409 will be further buffered. Since the two groups of buffer plates 409 are arranged in a "V" shape, and the sizes of the openings between the two groups of buffer plates 409 are different as the spacing between the two groups of limit blocks 404 is adjusted, the electronic components with suitable sizes will pass through the two groups of buffer plates 409 and the limit blocks 404 after the electronic components touch the surface of the buffer plates 409, while the screened electronic components will be blocked by the two groups of limit blocks 404, and the electronic components will be pushed against the surface of the buffer plates 409 to push the buffer plates 409 to rotate under the thrust of subsequent vibration, thereby preventing the electronic components from being damaged by hard extrusion. In addition, the surface of the buffer plates 409 is covered with a silicone sleeve to further reduce damage during collision.
[0026] The lower end surface of the limit block 404 is provided with uniformly distributed through holes 415, and a slider 416 is inserted inside each group of through holes 415. The lower end surface of the slider 416 is provided with a spherical limit groove, and a ball 417 is inserted in the spherical limit groove. The upper end surface of the slider 416 is fixedly connected with a spring B418, and the other end of the spring B418 is connected to the inner wall of the through hole 415. The slider 416 is pushed out of the through hole 415 under the elastic force of the spring B418, and the ball 417 is further exposed on the lower end surface of the limit block 404. When the electronic component passes the lower end of the limit block 404, the electronic component will contact the surface of the ball 417 during the sliding process of the electronic component, and the rolling friction between the ball 417 and the electronic component will further reduce the resistance of the electronic component when passing through, and at the same time prevent the electronic component from deviating in other directions during the vibration process, resulting in hard friction between the electronic component and the limit block 404, further causing damage to the surface of the electronic component. At the same time, limit sliders 419 are provided on the inner walls of both sides of the slider 416, and both sides of the slider 416 are fixedly connected to the limit slots 420, and the limit slots 420 are inserted in the limit slider 419 in a matching manner, so that the sliding stroke of the slider 416 in the through hole 415 is further limited, so that the slider 416 cannot slide out of the through hole 415 to block the passage of the electronic component.
[0027] When the screening mechanism 4 is screening the electronic components, the screened electronic components will be blocked by the screening mechanism 4, and unqualified electronic components will be further removed manually to achieve rapid screening of electronic components. At the same time, multiple groups of screening mechanisms 4 can be installed on the screening slide rail 3, and each group of screening mechanisms 4 has different screening parameters, further achieving multiple classification screening of electronic components.
