Multiple storage cavities are circumferentially distributed about the center line of the screening cylinder, and a sieve plate is provided above the inside of each of the multiple storage cavities.

[0004] Based on the aforementioned patent, the rotating drum driven by a motor is used to place products inside the drum. When the drum rotates above a certain screen plate, products of different sizes can be screened. However, relying solely on the rotation of the motor may cause the electronic components to adhere to the inner wall of the device under the action of centrifugal force, making it impossible to complete the screening. Furthermore, the screen plates of the aforementioned device cannot be disassembled or are not removable. If it is necessary to replace the screen plates with different apertures, it may be necessary to stop the machine and perform complex operations, which greatly reduces production efficiency. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an electronic component quality inspection and screening device, comprising a housing 1, a feed inlet 2 fixedly connected to the top of the housing 1 for feeding into the housing 1, a motor 3 fixedly connected to the outer wall of the rear end of the housing 1, the drive end of the motor 3 penetrating the housing 1 and fixedly connected to a rotating column 13, a vibration assembly provided on the outer wall of the rotating column 13, the rotating column 13 being connected to a vibrator 4 through the vibration assembly, the vibration assembly including a top column 14 disposed at the top of the rotating column 13, the front end of the rotating column 13 rotating on the inner wall of the housing 1, a plurality of impact crescent blocks 15 fixedly connected to the outer wall of the rotating column 13 for impacting the top column 14, a vibrator 4 fixedly connected to the top of the top column 14, a plurality of compression springs 12 fixedly connected to the bottom end of the vibrator 4, a bottom column 16 fixedly connected to the bottom end of the inner wall of the compression springs 12, and the bottom end of the bottom column 16 fixedly connected to the bottom end of the inner wall of the housing 1.

[0027] Specifically, the operator starts motor 3, which drives rotating column 13 to rotate via transmission device. The rotation of rotating column 13 causes the impact crescent blocks 15 on its outer wall to sequentially contact top column 14. Each contact causes top column 14 to be subjected to the force of the impact crescent blocks 15, moving it upwards. This upward movement of top column 14 acts on the compression spring 12 at the bottom of vibrator 4, causing the spring 12 to be stretched and then quickly rebound, driving vibrator 4 to return to its original position, generating one vibration. Simultaneously, the operator feeds the electronic components to be screened into the box through the feed inlet 2 at the top of box 1. The electronic components fall onto the first screen plate 8 under gravity. Under the vibration of vibrator 4, the electronic components begin to move slowly to the right, and most of them fall onto the second screen plate 9 through the drop groove 17 on the first screen plate 8. Then, the first screen plate 8 shakes under the action of the vibrator 4, causing large electronic components to move to the right with the shaking of the screen plate and complete the initial screening. Then, through the shaking of the second screen plate 9, the electronic components that have already been screened once are moved to the right. Then, through the drop groove 17 also opened on the second screen plate 9, smaller electronic components are allowed to fall into the vibrator 4. Then, smaller electronic components continue to move to the right with the movement of the second screen plate 9, while the smallest electronic components move to the right under the continuous vibration of the vibrator 4. Through this series of vibrations and movements, the electronic components are gradually screened and separated according to size and shape. Large components are left on the first screen plate 8, smaller components fall through the first screen plate 8 onto the second screen plate 9, and even smaller components fall through the second screen plate 9 into the vibrator 4, thus realizing the effective screening of electronic components of various shapes.

[0028] Reference Figure 4 and Figure 5The vibrator 4 has rotating columns 7 rotatably connected to both the front and rear sides of its right end. A flipper 5 is rotatably connected to the outer wall of the rotating column 7. A locking assembly is provided on the inner wall of the flipper 5. The flipper 5 is connected to a spring 19 via the locking assembly. The locking assembly includes a locking block 6 slidably connected to the inner wall of the flipper 5. The bottom end of the locking block 6 is fixedly connected to the spring 19. The bottom end of the spring 19 is fixedly connected to a round tube 20. The bottom end of the round tube 20 is fixedly connected to the bottom end of the inner wall of the flipper 5. Fixed columns 10 are rotatably connected to both the front and rear sides of the vibrator 4. The two fixed columns 10 are opposite to each other. One end is fixedly connected to the inside of the housing 1. The inner wall of the vibrator 4 is provided with a sliding groove 11. The sliding groove 11 is used to lock the locking block 6 onto the flipper 5. The upper and lower sides of the inner wall of the vibrator 4 are provided with locking slots 18. The upper locking slot 18 is used to lock the first screen plate 8, and the lower locking slot 18 is used to lock the second screen plate 9. The inner walls of the first screen plate 8 and the second screen plate 9 are provided with several drop grooves 17. The drop grooves 17 on the first screen plate 8 are used to screen larger electronic components, and the drop grooves 17 on the second screen plate 9 are used to screen smaller electronic components.

[0029] Specifically, the staff first prepares the first screen plate 8 and the second screen plate 9 to be replaced, ensuring that the new screen plates meet the screening requirements. Then, the staff presses down on the locking block 6 on one side of the device to compress the spring 19 at the bottom of the locking block 6 and to allow the locking block 6 to slide down into the groove 11 on the vibrator 4. After the locking block 6 has slid into place, the staff pulls the flipper 5 to the right. The flipper 5 can then rotate to the right with the assistance of the rotating column 7. This action is considered to release the restriction on the locking block 6. When both flippers 5 on both sides of the vibrator 4 have completed rotation, the restriction is considered to be released, and the staff can then proceed with the process of flipping the device. The first screen plate 8 and the second screen plate 9 are added into the blocking slot 18 while ensuring that the screen plates are correctly placed. After the first screen plate 8 and the second screen plate 9 are put in, the operator rotates the flipper 5 in the opposite direction to return it to the initial position and releases it. At this time, the spring 19 returns to its original position and the locking block 6 is locked into the slide groove 11 again. Then the operator gently shakes the first screen plate 8 and the second screen plate 9. If they do not loosen during the shaking, it indicates that they are firmly installed in the slot 18 and can then be used. The above structure allows the operator to quickly and efficiently replace the screen plates without complicated tools or long downtime, which greatly improves production efficiency and equipment flexibility.

[0030] Working principle: First, the operator presses down on the locking block 6 on one side of the device, causing the locking block 6 to compress the spring 19 at its bottom. Simultaneously, the locking block 6 slides downwards through the groove 11 of the vibrator 4. Then, the operator pulls the flipper 5 to the right. With the help of the rotating column 7, the flipper 5 can rotate to the right, indicating that the restriction has been released. After both flippers 5 on both sides of the vibrator 4 have rotated, the user can then add the first sieve plate 8 and the second sieve plate 9 into the groove 18 that was previously blocked by the flipper 5. After the first screen plate 8 and the second screen plate 9 are inserted, the flipper 5 is rotated in the opposite direction and released, allowing the spring 19 to return and reset, locking the locking block 6 back into the slide groove 11. Then, the first screen plate 8 and the second screen plate 9 are shaken until they are confirmed to be immovable, at which point they can be put into use. The motor 3 is then started, driving the rotating column 13 to rotate. Simultaneously, the rotating column 13's outer wall impact crescent block 15 contacts the top column 14, causing the top column 14 to move upwards upon impact with the crescent block 15. The vibrator 4 moves upward, causing the spring 12 at the bottom of the vibrator 4 to be stretched and then rebound, resetting the vibrator 4 and generating one vibration. Then, electronic components are fed into the housing 1 through the feed port 2 on the top of the housing 1. After falling onto the first screen plate 8, the electronic components are slowly moved to the right by the vibration of the vibrator 4. Then, most of the electronic components fall onto the second screen plate 9 through the drop groove 17 on the first screen plate 8. Then, the large electronic components move to the right as the first sieve plate 8 shakes. Then, the second sieve plate 9 shakes, causing it to move to the right with the components that have already been sieved once. Then, smaller electronic components fall into the vibrator 4 through the drop groove 17 opened on the second sieve plate 9. Then, smaller electronic components move to the right as the second sieve plate 9 moves. Then, the smallest electronic components move to the right as the vibrator 4 shakes, thus sieving electronic components of various shapes.
