Description

Technical Field

[0001] The present application relates to the field of filtration, and in particular to an automatic discharge machine for MGP packaging mold cakes. Background Art

[0002] The domestic semiconductor manufacturing industry is currently entering a mature stage. The rapid emergence of ultra-high-speed computers, digital audio and video, mobile communications, and portable electronic devices has directly driven advancements in chip electronic packaging technology. Against this backdrop, the manufacturing industry is becoming increasingly intelligent, but the level of automation in semiconductor circuit packaging remains low. Manual material feeding, encapsulation, and removal are typically performed, resulting in heavy workloads and high labor intensity, but low efficiency.

[0003] To address this situation, people have designed an automatic discharging machine that uses a control system to control air grippers to automatically arrange and place the cakes, reducing the burden on workers. However, the friction and collision between a large number of cakes will generate a lot of dust, which will not only cause excessive smoke and dust in the workshop and exceed the dust content, but also the workers working nearby will accidentally inhale the dust, causing harm to their bodies.

[0004] Therefore, we need to provide an MGP packaging mold cake automatic discharge machine with dust removal, which uses a rotating dust filter to filter and purify the gas in a circular motion. At the same time, the pressure of the elastic airbag can be used to provide a thrust to the dust filter, causing it to automatically vibrate back and forth to shake out the dust, thereby ensuring long-term use of the dust filter. Summary of the Invention

[0005] The object of the present application is to solve the problem that a large amount of dust is generated during the discharge process of MGP packaging mold cakes. Compared with the prior art, an automatic discharge machine for MGP packaging mold cakes is provided, which includes a device body, a dust collection box fixedly connected to the outer end of the device body, a dust collection pipe fixedly connected to the top of the dust collection box, a dust collection hood fixedly connected to the bottom end of the dust collection box, an inner top surface of the dust collection box fixedly connected to an inlet pipe connected to the dust collection pipe, an inner wall of the dust collection box fixedly connected to a mounting plate, one side of the mounting plate fixedly connected to a dust suction pump and a reduction motor, an input end of the dust suction pump fixedly connected to the inlet pipe, an output end of the dust suction pump fixedly connected to the outlet pipe, an outer end of the outlet pipe fixedly connected to a dust filter box, an outer end of the dust filter box fixedly connected to a first air pipe, one end of the first air pipe is fixedly connected to an elastic sleeve and is communicated, an outer end of the elastic sleeve is fixedly connected to a second air pipe, the second air pipe and the exhaust pipe are communicated with each other, the output end of the reduction motor passes through the interior of the dust filter box, and the internal rotation connection of the dust box A turntable is connected, and an annular hole groove 1 and an annular hole groove 2 are opened on the turntable. The inner wall of the annular hole groove 1 is fixedly connected with an elastic dust filter net, and the inner wall of the annular hole groove 2 is fixedly connected with an elastic cloth. One end of the air outlet pipe and the first air pipe extends to the interior of the dust filter box and slides on the outer end of the elastic dust filter net. By setting a dust removal box, a dust suction pump is used to send the dust-containing gas into the dust filter box. After being filtered by the rotating elastic dust filter net, it comes to the interior of the elastic sleeve and gathers there, forcing the elastic sleeve to gradually expand until it squeezes the area where the elastic dust filter net is adhered to the dust. When the pressure threshold value of the pressure limiting valve is reached, the elastic sleeve begins to contract, causing the elastic dust filter net to start vibrating back and forth under the action of the elastic force, giving the dust an initial velocity to move to the right. At this time, the water-absorbing fibers are squeezed by the movable plate, and the water squeezed out forms a large number of water droplets at the water outlet. The dust collides with the water droplets and adheres to the water droplets, and finally, under the action of gravity, rolls down and is collected by the dust collection box, completing a series of dust shaking-off-capture-collection tasks.

[0006] Furthermore, the inner wall of the second air pipe is fixedly connected to the pressure limiting valve, the outer end of the dust filter box is provided with a slot, the inner wall of the slot is fixedly connected to a flexible cloth, and the elastic sleeve corresponds to the position of the flexible cloth.

[0007] Furthermore, a dust outlet is provided at the bottom of the dust filter box, and the inner bottom surface of the dust removal box is slidably connected to the dust collection box located below the dust filter box. A cabinet door is provided at the outer end of the dust removal box, which is convenient for cleaning the dust inside the dust collection box by opening the cabinet door.

[0008] Furthermore, a pair of annular baffles are fixedly connected to the outer end of the elastic dust filter, and the air outlet pipe slides between the pair of annular baffles.

[0009] Furthermore, a dust sticking box is fixedly connected to the inner wall of the dust filter box, and the output end of the reduction motor movably penetrates into the interior of the dust sticking box.

[0010] Furthermore, water-absorbing fibers are provided inside the sticky dust box. The water-absorbing fibers are in a saturated state and are responsible for preventing water from flowing out directly.

[0011] Furthermore, a movable plate is slidably connected to the inner wall of the dust sticky box, and a plurality of elastic ropes are fixedly connected to the inner wall of the dust sticky box near the elastic dust filter, and one end of the plurality of elastic ropes is fixedly connected to one end of the movable plate.

[0012] Furthermore, the side end of the movable plate contacts the side end of the water-absorbing fiber, and the outer end of the dust sticking box close to the elastic dust filter is provided with a plurality of evenly distributed water outlet holes.

[0013] Furthermore, a hydrophobic film is laid on the outer end of the dust sticky box close to the elastic dust filter to prevent water droplets from leaving traces outside the dust sticky box.

[0014] Furthermore, the device body also includes a vibration mechanism, a discharge mechanism, a lifting mechanism and a feeding mechanism, and the vibration mechanism, the discharge mechanism, the lifting mechanism and the feeding mechanism are all electrically connected to a control system.

[0015] Compared with the prior art, the advantages of this application are:

[0016] (1) By setting up a dust removal box, a dust suction pump is used to send the dust-containing gas into the dust filter box. After being filtered by the rotating elastic dust filter, the gas comes into the elastic sleeve and gathers there, forcing the elastic sleeve to gradually expand until it squeezes the area of ​​the elastic dust filter with dust. When the pressure threshold value of the pressure limiting valve is reached, the elastic sleeve begins to shrink, causing the elastic dust filter to start vibrating back and forth under the action of elastic force, giving the dust an initial velocity to move to the right. At this time, the water-absorbing fibers are squeezed by the movable plate, and the water squeezed out forms a large number of water droplets at the water outlet. The dust collides with the water droplets and adheres to the water droplets. Finally, under the action of gravity, it rolls down and is collected by the dust collection box, completing a series of dust shaking-capturing-collecting tasks.

[0017] (2) The dust-containing gas is sent into the dust filter box through a vacuum pump. After being filtered by the elastic dust filter, the gas enters the inside of the elastic sleeve and gathers there, causing the elastic sleeve to gradually expand. At this time, the elastic dust filter is in a rotating state, and the area with dust on it begins to be squeezed by the elastic sleeve through the flexible cloth. When the pressure threshold value of the pressure limiting valve is reached, the pressure limiting valve begins to deflate, the elastic sleeve begins to shrink, and the elastic dust filter that has lost its supporting force begins to vibrate back and forth under the action of elastic force, shaking off the dust stuck to it, thereby achieving the purpose of cleaning the elastic dust filter.

[0018] (3) The material cakes can be sent up little by little by setting up a vibration mechanism, and the discharge mechanism arranges multiple material cakes in a specific position. Then the pushing mechanism pushes multiple material cakes to the specified position on the feeding arm, and the feeding arm is driven by the servo motor to complete the precise feeding.

[0019] (4) Since a large amount of dust is in a floating state after sliding to the right for a distance, by setting up a dust sticking box, the movable plate squeezes out the moisture inside the water-absorbing fiber, and forms a large number of water droplets through multiple evenly arranged water outlet holes, so that the dust is adhered by a large number of water droplets during the operation. Under the action of gravity, the water droplets adhered to a large amount of dust begin to fall and eventually fall into the dust collecting box, thereby achieving the purpose of attracting and cleaning the dust.

[0020] (5) By setting up a hydrophobic film, it is possible to effectively avoid water stains remaining on the dust sticking box, causing the water droplets behind to slide down directly along the water marks, thereby improving the dust sticking efficiency of the water droplets in the device.

[0045] Example 2:

[0046] This application discloses an automatic discharging machine for MGP packaging mold cakes.
