DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Please refer to Figures 1-9 An embodiment of the present application is: a vacuum recycling assembly of electronic components, comprising a fixed assembly 1, a vacuum generator 2 is fixed on the left side of the fixed assembly 1, the vacuum generator 2 is communicated with the fixed assembly 1 through a pipeline, an inlet and outlet pipe 3 is fixed on the right side of the fixed assembly 1, the inlet and outlet pipe 3 is communicated with the fixed assembly 1, a sealing assembly 4 is fixed on the outer wall of the fixed assembly 1, a cup body 5 is attached to the inner wall of the sealing assembly 4, a suction port 6 is formed on the bottom surface of the cup body 5, and an interception device for automatically blocking the falling of electronic components when the vacuum generator 2 is closed is arranged in the cup body 5.

[0021] The intercepting device comprises a fixed rod 71, a baffle 72, a first limiting strip 73, a second limiting strip 74, a through hole 75, a hanger rod 76 and a counterweight 77. The fixed rod 71 is fixedly connected to the inner wall of the cup body 5. The fixed rod 71 penetrates the baffle 72 and is rotationally connected at the penetration position. The outer wall of the baffle 72 is attached to the inner wall of the cup body 5. The first limiting strip 73 is fixedly connected to the inner wall of the left side of the cup body 5. The right end of the baffle 72 is rotated under the upward thrust and no longer shields the inside of the cup body 5. The inside of the cup body 5 is completely opened. The electronic components below the suction port 6 are affected by the negative pressure generated by the vacuum airflow and are sucked into the cup body 5. The second limiting strip 74 is fixedly connected to the inner wall of the right side of the cup body 5. The through hole 75 is arranged at the right end of the baffle 72. The hanger rod 76 is hingedly connected to the bottom surface of the baffle 72. The counterweight 77 is fixedly connected to the end of the hanger rod 76 away from the baffle 72. Since the through hole 75 is arranged at the right end of the baffle 72, the hanger rod 76 and the counterweight 77 at the bottom of the baffle 72 are affected by the vacuum airflow flowing out of the through hole 75 and are adsorbed. When the hanger rod 76 and the counterweight 77 move to the baffle 72, they hit the right end of the baffle 72 and apply an upward thrust to the baffle 72, pushing the right end of the baffle 72 to rotate upward. When the recovery is completed, the vacuum generator 2 is closed, air rapidly enters the cup body 5, the hanger rod 76 and the counterweight 77 are no longer adsorbed by the vacuum airflow and are affected by gravity to fall downward. When the counterweight 77 falls downward, it pulls the baffle 72 to rotate through the hanger rod 76. The inner wall of the cup body 5 is provided with fixed first and second limiting strips 73 and 74, so that when the baffle 72 is rotated to the horizontal position under the influence of the gravity of the counterweight 77, the baffle 72 is limited by the first and second limiting strips 73 and 74 and stops rotating, so that the baffle 72 is completely reset and shields the inside of the cup body 5. The intercepting device automatically closes the intercepting device in the cup body 5 when the vacuum generator 2 is closed, by arranging the fixed rod 71, the baffle 72, the first and second limiting strips 73 and 74, the hanger rod 76 and the counterweight 77. The distance between the electronic components and the counterweight 77 pulls apart the electronic components to fall and the speed of the rotation of the baffle 72, so that the electronic components do not fall out of the cup body 5 when falling, thereby facilitating the recovery of the electronic components and avoiding the electronic components from falling out of the cup body 5 after the vacuum generator 2 is closed, solving the problem that the electronic components are easily directly dropped from the suction port 6 when not being adsorbed. When the vacuum generator 2 is opened, the through hole 75, the hanger rod 76 and the counterweight 77 apply a thrust to the baffle 72, so that the baffle 72 is automatically rotated and opened, facilitating the electronic components to be sucked into the cup body 5 through the suction port 6 and to rise above the baffle 72 and the counterweight 77 under the influence of the suction force, thereby increasing the distance between the counterweight 77 and the electronic components and avoiding the counterweight 77 and the electronic components from falling at the same time, solving the problem that the electronic components easily fall on the same horizontal line as the counterweight 77 and affect the interception of the electronic components by the baffle 72.

[0022] In this embodiment, when the vacuum generator 2 is turned on, the air generated by the vacuum generator 2 is discharged from the inlet and outlet pipes 3. The vacuum generator 2 uses the negative pressure to adsorb the cup body 5 onto the bottom surface of the fixing component 1. Then, the gap between the fixing component 1 and the cup body 5 is sealed by the sealing component 4. The electronic components are sucked into the cup body 5 from the suction port 6.

[0023] When the vacuum generator 2 is turned on, the negative pressure generated by the vacuum airflow attracts the cup body 5 to the bottom of the fixing component 1, and then continues to form a negative pressure inside the cup body 5. Since the right end of the baffle 72 has a through hole 75, the hanging rod 76 and the counterweight 77 at the bottom of the baffle 72 are also attracted by the vacuum airflow flowing out of the through hole 75. The hanging rod 76 and the counterweight 77 are attracted and move upward. When the hanging rod 76 and the counterweight 77 move to the baffle 72, they impact the right end of the baffle 72, applying an upward force to the baffle 72. The thrust causes the right end of baffle 72 to lose its horizontal position after being pushed upwards. Since the center of baffle 72 is pierced by the fixing rod 71, and the piercing point can rotate, the right end of baffle 72 rotates after being pushed upwards. The lifting rod 76 and counterweight 77 continue to move upwards under the negative pressure generated by the vacuum airflow, causing baffle 72 to rotate to a vertical position, no longer obstructing the interior of cup 5. At this point, the interior of cup 5 is completely open, and the vacuum airflow inside continues to flow downwards, below the suction port 6. Electronic components are drawn into cup 5 due to the negative pressure generated by the vacuum airflow. Upon completion of the recovery, the vacuum generator 2 is shut off, and air quickly enters cup 5. The lifting rod 76 and counterweight 77 are no longer attracted by the vacuum airflow and fall downwards under the influence of gravity. As the counterweight 77 falls, it pulls the baffle 72 to rotate via the lifting rod 76. Since the inner wall of cup 5 is equipped with a fixed first limiting strip 73 and a second limiting strip 74, when the baffle 72 rotates to a horizontal position under the influence of the counterweight 77's gravity, the baffle 72... The rotation stops due to the restriction of the first limiting bar 73 and the second limiting bar 74, so that the baffle 72 is completely reset and forms a shield inside the cup body 5. When the vacuum generator 2 is turned off, the electronic components are also affected by gravity and fall downward. Since the height that the electronic components rise when they are attracted by the vacuum airflow is much greater than that of the counterweight 77, when the counterweight 77 falls and drives the baffle 72 to reset, the electronic components do not fall out completely. At this time, the electronic components can be intercepted inside the cup body 5, preventing the electronic components from falling out after the vacuum generator 2 is turned off.

[0024] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the inside of the cup body 5 is provided with an auxiliary device to prevent electronic components from being stuck when the closing interception device is used. The auxiliary device includes a connecting rod 81, a filter plate 82, a movable ball 83, a rubber flexible rod 84, a sliding block 85, a sliding groove 86, a hinge plate 87, a scraper 88, and a thrust spring 89. The connecting rod 81 is hinged to the upper surface of the baffle 72. When the baffle 72 rotates counterclockwise, it drives the connecting rod 81 to rotate. The filter plate 82 is slidably connected to the inner wall of the cup body 5. The rotation of the connecting rod 81 pushes the filter plate 82 to slide upward. The filter plate 82 intercepts the electronic components, preventing them from being directly sucked into the vacuum generator 2 and other parts due to the influence of the vacuum airflow. The end of rod 81 away from baffle 72 is hinged to the bottom surface of filter plate 82. Two sets of movable balls 83 are provided. One set of movable balls 83 penetrates the filter plate 82 and fits at the penetration point. When the filter plate 82 slides upward, it also drives the movable balls 83 to move upward. The two ends of rubber flexible rod 84 are fixedly connected to the outer walls of the two sets of movable balls 83. A detachable filter screen is fixed between the two sets of movable balls 83, and half of the filter screen is fixedly connected to the outer wall of rubber flexible rod 84. Movable balls 83 push rubber flexible rod 84 to bend. Sliding block 85 is slidably connected to the inner wall of cup body 5. The other set of movable balls 83 is slidably connected to the side wall of sliding block 85. The two sets of movable balls 83 cooperate with rubber flexible rod 84 to push sliding block 85 to slide. Sliding groove 86 is provided. On the inner wall of the cup body 5, the outer wall of the sliding block 85 fits against the inner wall of the sliding groove 86. The hinge plate 87 is hinged to the side wall of the connecting rod 81. When the connecting rod 81 rotates, it drives the hinge plate 87 to rotate as well. The scraper 88 is fixedly connected to the end of the hinge plate 87 away from the connecting rod 81. The thrust spring 89 is fixedly connected to the upper surface of the hinge plate 87. The thrust spring 89 is subjected to the mutual force between the filter plate 82 and the baffle 72 and is always in a compressed state. When the left end of the baffle 72 rotates downward, the scraper 88 is no longer supported by the baffle 72 and moves downward under the restoring force of the thrust spring 89. The hinge plate 87 is also attracted by the vacuum airflow. The scraper 88 slides on the inner wall of the cup body 5 and separates from the baffle 72. When the vacuum generator 2 is turned off, the connecting rod 81 resets, causing the hinge plate 87 and the scraper 88 to also reset. Since the scraper 88 is separated from the baffle 72 and is attached to the inner wall of the cup body 5, when the scraper 88 resets, it passes over the bottom surface of the first limit bar 73, scraping out any electronic components that may be stuck on the bottom surface of the first limit bar 73. When the vacuum generator 2 is turned off, this auxiliary device works with the connecting rod 81, filter plate 82, movable ball 83, rubber soft rod 84, sliding block 85 and sliding groove 86 to catch and concentrate the electronic components through the detachable filter screen, thereby avoiding the need for staff to pick out the electronic components with tools or manually when taking out the recycled electronic components, and solving the problem that the recycled electronic components are difficult to take out from the cup body 5. When the baffle 72 is closed, the articulated plate 87, the scraping rod 88 and the thrust spring 89 cooperate to sweep the electronic components that may be blocked by the limiting strip around the cup body 5, thereby avoiding the electronic components from being stuck between the baffle 72 and the limiting strip to hinder the closing of the baffle 72, reducing the risk of the electronic components being pinched by the baffle 72 and the limiting strip, and solving the problem that the electronic components easily affect the normal operation of the interception device.

[0025] The outer wall of the cup body 5 is provided with a fixing device for preventing the cup body 5 from falling, which comprises a fixing ring 91, a fixing block 92, a fixing column 93, a first limiting block 94, a second limiting block 95, an arc-shaped spring rod 96 and a buckle 97. The fixing ring 91 is fixedly connected to the outer wall of the cup body 5, the fixing block 92 is fixedly connected to the upper surface of the fixing ring 91, one end of the fixing column 93 is fixedly connected to the side wall of the fixing block 92, and the other end of the fixing column 93 is fixedly connected to the outer wall of the cup body 5. When the cup body 5 is inserted upward into the fixing assembly 1, the fixing ring 91, the fixing block 92 and the fixing column 93 of the outer wall of the cup body 5 move upward together with the cup body 5. The first limiting block 94 is fixedly connected to the outer wall of the cup body 5, and the second limiting block 95 is fixedly connected to the bottom surface of the fixing assembly 1. The side wall of the first limiting block 94 is in contact with the side wall of the second limiting block 95, and the first limiting block 94 and the second limiting block 95 are in contact with each other. The first limiting block 94 and the second limiting block 95 limit the cup body 5 to avoid rotating on the bottom surface of the fixing assembly 1. One end of the arc-shaped spring rod 96 is fixedly connected to the bottom surface of the second limiting block 95, and the buckle 97 is hingedly connected to the bottom surface of the second limiting block 95. The other end of the arc-shaped spring rod 96 is fixedly connected to the side wall of the buckle 97. When the fixing column 93 moves to the buckle 97, the fixing column 93 pushes the buckle 97 to rotate away from the fixing column 93, and the buckle 97 rotates clockwise to compress the arc-shaped spring rod 96. When the fixing column 93 continues to move upward to be separated from the buckle 97, the buckle 97 is no longer pushed by the fixing column 93, but is reset by the elastic force of the arc-shaped spring rod 96 recovering, and rotates to the bottom surface of the fixing column 93 to support the fixing column 93. When the cup body 5 is connected to the fixing assembly 1, the fixing ring 91, the fixing block 92, the fixing column 93, the first limiting block 94, the second limiting block 95, the arc-shaped spring rod 96 and the buckle 97 limit the cup body 5 to avoid falling directly under the influence of gravity when the vacuum generator 2 is closed, thereby causing the recovered electronic components to be scattered or the device to be damaged, and solving the problem that the cup body 5 easily falls directly when not being adsorbed by the vacuum airflow.

[0026] When the vacuum generator 2 is turned on, the baffle 72 rotates counterclockwise, and the right end of the baffle 72 rotates upward. When the right end of the baffle 72 rotates upward, the connecting rod 81 and the hinge joint of the baffle 72 also rotate around the fixed rod 71. The far end of the connecting rod 81 is hinged to the center of the filter plate 82, and the filter plate 82 can only slide up and down. Therefore, the hinge joint of the filter plate 82 and the connecting rod 81 can only move up and down. When the hinge joint of the connecting rod 81 and the baffle 72 rotates around the fixed rod 71, the connecting rod 81 also rotates by itself. The connecting rod 81 pushes the filter plate 82 to slide upward, increases the distance between the filter plate 82 and the baffle 72, and increases the distance between the electronic components and the counterweight 77 when the electronic components are adsorbed. At the same time, the electronic components are intercepted by the filter plate 82 to avoid being directly sucked into the vacuum generator 2 and other parts by the vacuum airflow. When the filter plate 82 slides upward, it also moves the movable ball 83 upward. The outer wall of the movable ball 83 is fixedly connected with the rubber soft rod 84, and the movable ball 83 far from the rubber soft rod 84 and far from the filter plate 82 is slidingly connected to the side wall of the sliding block 85. At the same time, the sliding block 85 can only slide along the sliding groove 86. Therefore, when the filter plate 82 slides upward, the distance between the two groups of movable balls 83 increases, and the rubber soft rod 84 slides the sliding block 85 along the sliding groove 86 by pulling the rubber soft rod 84, so that the rubber soft rod 84 is straightened. When the rubber soft rod 84 is straightened, the filter screen between the two groups of movable balls 83 is close to the rubber soft rod 84, so that the filter screen is retracted. When the vacuum generator 2 is turned off, the baffle 72 is rotated back by the pulling force of the counterweight 77, and the connecting rod 81 is also rotated. The connecting rod 81 pulls the filter plate 82 to slide downward, and the filter plate 82 moves the movable ball 83 downward when it slides downward. The movable ball 83 exerts a pushing force on the rubber soft rod 84 when it moves downward, so that the rubber soft rod 84 is bent, and the sliding block 85 is pushed to slide. The sliding block 85 moves the movable ball 83 far from the filter plate 82, so that the filter screen between the two groups of movable balls 83 is separated from the rubber soft rod 84, and the filter screen is unfolded to support the electronic components. When the connecting rod 81 rotates, the hinge plate 87 also rotates. The repulsive spring 89 is always in a compressed state. When the left end of the baffle 72 rotates downward, the scraping rod 88 is no longer supported by the baffle 72, and at the same time, the scraping rod 88 is moved downward by the repulsive force of the repulsive spring 89. The hinge plate 87 is also adsorbed by the vacuum airflow. The scraping rod 88 slides on the inner wall of the cup body 5 and separates from the baffle 72. When the scraping rod 88 is reset, it passes the bottom surface of the first limiting strip 73, so that the electronic components that may be stuck in the bottom surface of the first limiting strip 73 are scraped out, avoiding the electronic components being stuck between the baffle 72 and the first limiting strip 73, which hinders the baffle 72 from resetting and closing.

[0027] When the cup 5 is inserted into the fixing assembly 1 upwardly, the fixing ring 91, the fixing block 92 and the fixing column 93 of the outer wall of the cup 5 move upwardly together with the cup 5, when the fixing column 93 moves to the buckle 97, the outer wall of the fixing column 93 slides with the inclined surface of the buckle 97, the fixing column 93 pushes the buckle 97 to rotate away from the fixing column 93, the clockwise rotation of the buckle 97 compresses the arc spring rod 96, when the fixing column 93 continues to move upwardly to be separated from the buckle 97, the buckle 97 is no longer pushed by the fixing column 93, and is reset by the elastic force of the arc spring rod 96 to restore, rotates to the bottom surface of the fixing column 93 to support the fixing column 93, the first limiting block 94 and the second limiting block 95 are staggered to each other to fit, the cup 5 is limited, the cup 5 is prevented from rotating on the bottom surface of the fixing assembly 1, the fixing column 93 is separated from the support of the buckle 97, and falls when the vacuum generator 2 is closed.

[0028] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
