Description

Technical Field

[0001] This invention relates to the field of memory module sorting technology, specifically to a sorting device for cleaning residual adhesive from memory modules. Background Technology

[0002] In the semiconductor memory manufacturing process, brand labels are affixed to the surface of the memory chip particles of the finished memory modules before they leave the factory. When a specific customer requires the chip to be disassembled, the label must be removed first. This process often leaves a layer of stubborn thermally conductive silicone on the delicate chip surface. If this residue is not completely removed, it will directly interfere with subsequent precision processes such as chip-level testing, reballing, or high-end repackaging, resulting in yield loss and increased production costs.

[0003] Due to the extremely high requirements for the appearance and functional integrity of brand-new components, the traditional rough sorting methods used for recycling used memory modules are completely unfeasible. Existing sorting devices attempt to use a combination of visual positioning and mechanical grippers. However, because finished memory modules are uniformly sized and extremely precise, even the slightest mechanical scratch can cause unacceptable damage. The surface of memory modules, after thorough cleaning and drying to achieve a dust-free environment, has a lower coefficient of friction. This makes the rigid grippers prone to slippage during high-speed sorting, requiring increased clamping force to compensate, which inadvertently increases the risk of memory module deformation or brittle fracture at the edges. Furthermore, the dynamic inertia under high-speed operation can also cause microscopic slippage of the memory module at the clamping point, scratching the expensive gold contacts or surrounding circuitry, reducing sorting efficiency and reliability, and potentially causing secondary damage to the memory module itself, directly affecting its subsequent reuse value.

[0004] Therefore, it is necessary to provide a sorting device for cleaning residual adhesive from memory modules to solve the above problems. Summary of the Invention

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1-12 This invention provides a technical solution: a sorting device for cleaning residual adhesive from memory modules, comprising a frame 1, a feeding mechanism 2, a cleaning mechanism 3, a sorting and unloading mechanism 4, several feeding baskets 5, and several unloading baskets 6. The feeding mechanism 2, the cleaning mechanism 3, and the sorting and unloading mechanism 4 are all located on the top of the frame 1, and the feeding mechanism 2 and the sorting and unloading mechanism 4 are respectively located on both sides of the cleaning mechanism 3. The frame 1 serves as the supporting steel frame for the entire device and is located above the factory floor. The feeding mechanism 2 is used to transfer memory modules from the feeding baskets 5 one by one into the cleaning mechanism 3. The cleaning mechanism 3 is used to clean the memory modules. The sorting and unloading mechanism 4 is used to transfer the cleaned memory modules to the unloading baskets 6. The feeding baskets 5 are used to place the memory modules to be cleaned, and the unloading baskets 6 are used to collect and store the cleaned memory modules.

[0041] Specifically, such as Figure 2 and Figure 3 As shown, the feeding mechanism 2 includes two sets of feeding modules 21, two sets of unloading modules 22, and an infeed module 26. The feeding modules 21 and unloading modules 22 are fixed on the top of the frame 1. The two sets of feeding modules 21 and the two sets of unloading modules 22 are located on both sides of the infeed module 26. The feeding basket 5 is placed on the feeding modules 21 and unloading modules 22. The feeding module 21 is driven by a motor and a pulley, and the unloading module 22 adopts a roller structure without a drive structure.

[0042] Four sets of material transfer modules 23 are fixed on the top of the frame 1. The material transfer modules 23 are driven by a combination of horizontal and vertical cylinders and have a material transfer plate at the end. The material transfer modules 23 are used to drive the material transfer plate to complete the horizontal movement along the conveying direction of the feeding module 21 and the vertical lifting movement. The four sets of material transfer modules 23 correspond to the positions of the two feeding modules 21 and the two unloading modules 22, respectively. The four sets of material transfer modules 23 are located below the middle of the two feeding modules 21 and the two unloading modules 22, respectively. The material transfer modules 23 corresponding to the position of the feeding module 21 are used to move the feeding basket 5 on the feeding module 21 to the side closer to the infeed module 26. The material transfer modules 23 corresponding to the position of the unloading module 22 are used to move the feeding basket 5 on the unloading module 22 to the side away from the infeed module 26.

[0043] like Figure 2 and Figure 3 As shown, a basket lifting module 24 and a pushing module 25 are respectively provided on both sides of the feeding module 26. The basket lifting module 24 is fixed to the top of the frame 1. The basket lifting module 24 adopts a lifting structure with motor-driven screw transmission and a suction cup structure. The basket lifting module 24 is used to adsorb the feeding basket 5 and drive the feeding basket 5 to move up and down. The pushing module 25 is fixed at a certain height on the frame 1 through a connecting block. The pushing module 25 adopts a structure with a push plate fixed at the end of a cylinder. The pushing module 25 is used to push the memory stick in the feeding basket 5 to the feeding module 26 after the feeding basket 5 is lifted to a certain height by the basket lifting module 24.

[0044] like Figure 2 As shown, a transverse module 27 is provided at the bottom of the feeding module 26. The transverse module 27 adopts a dual-axis moving structure combined with a push plate, and transverse seats are provided on both sides of the dual-axis moving structure. The transverse seats are located at the ends of the loading module 21 and the unloading module 22 near the feeding module 26. The transverse seats are located below the suction cup of the basket lifting module 24. The transverse seats are used to receive the loading basket 5. The transverse module 27 is used to drive the push plate to move along the setting direction and vertical direction of the feeding module 26, thereby enabling the empty loading basket 5 below the basket lifting module 24 to be moved to the end near the unloading module 22.

[0045] Furthermore, such as Figure 4 As shown, the feeding module 26 includes a single-axis moving seat 262, a movable plate 263, two sets of pusher plates 268, and two sets of flipping guides. A bracket 261 is fixedly connected to the frame 1. The bracket 261 is located between the two feeding modules 21. The single-axis moving seat 262 is fixed on the top of the bracket 261. The movable plate 263 is set on the single-axis moving seat 262. The movable plate 263 is C-shaped and its opening faces the cleaning mechanism 3. The two sets of pusher plates 268 are fixed on the side of the movable plate 263. The two sets of flipping guides are fixed on both sides of the bracket 261. The positions of the two sets of flipping guides correspond to the positions of the two sets of pusher plates 268. The single-axis moving seat 262 is used to drive the movable plate 263 to move closer to or further away from the cleaning mechanism 3. The movable plate 263 is used to push memory modules.

[0046] Furthermore, such as Figure 4As shown, the flipping guide includes a guide plate 264, a cylinder 265, a flipping plate 266, and a guide groove 267. The guide groove 267 is fixed to the top of the bracket 261, and the guide plate 264 is fixed to the top of the guide groove 267. The guide plate 264 is vertically arranged. The cylinder 265 is fixed to the bottom of the bracket 261. The output end of the cylinder 265 is hinged to the side of the flipping plate 266. The flipping plate 266 is hinged to the top edge of the guide groove 267. When the cylinder 265 extends, it can drive the flipping plate 266 to rotate around the guide groove 267. The hinge 267 rotates towards the side closer to the guide plate 264, causing the horizontal flip plate 266 to gradually rotate into a vertical state. During this process, the memory module slides into the guide groove 267 by its own gravity, thus flipping the horizontally placed memory module on the flip plate 266 into a vertical state. The retraction of the cylinder 265 can drive the flip plate 266 to rotate away from the guide plate 264 around the hinge between the flip plate 266 and the guide groove 267, causing the vertical flip plate 266 to gradually rotate into a horizontal state and return to the initial position of the flip plate 266.

[0047] It should be noted that, in the initial state, the movable plate 263 and the pusher plate 268 fixed thereon are located on the side of the guide plate 264 away from the cleaning mechanism 3. The movable plate 263 is provided with a through groove corresponding to the position of the guide plate 264 and a limiting groove corresponding to the position of the memory module on the guide groove 267.

[0048] In actual operation, the worker or robot places the loading basket 5 containing the memory modules to be cleaned onto the loading module 21. The loading module 21 is activated, and the corresponding transfer module 23 is activated, moving a group of loading baskets 5 near the infeed module 26 to the transverse transfer seat of the transverse transfer module 27. Then, the basket lifting module 24 is activated, and its suction cups adsorb the loading baskets 5 and drive them to rise gradually to a set height. The pushing module 25 pushes the memory modules on the loading baskets 5 one by one onto the horizontal flipping plate 266. Then, by flipping, the horizontal memory modules are flipped to a vertical position. After that, the cylinder 265 retracts, so that the flipping plate 266 returns to its initial state. Then, the single-axis moving seat 262 starts to run forward, driving the movable plate 263 and the pushing plate 268 to move towards the side closer to the cleaning mechanism 3. The pusher plate 268 pushes the memory module located in the guide groove 267 towards the side of the cleaning mechanism 3 until the memory module is pushed into the cleaning mechanism 3, where the cleaning mechanism 3 cleans the memory module. After the basket lifting module 24 adsorbs and drives the rising loading basket 5 to push all the memory modules onto the feeding module 26, the basket lifting module 24 drives the empty loading basket 5 to descend and release the adsorption. Then, the horizontal moving module 27 operates, moving the loading basket 5 below the basket lifting module 24 to one end closer to the unloading module 22. Then, the transfer module 23, which corresponds to the position of the unloading module 22, moves the loading basket 5 on the horizontal moving module 27 to one end of the transfer module 23 away from the feeding module 26. Finally, the staff removes the empty loading basket 5, completing the loading of memory modules and the automatic loading and unloading of the loading basket 5.

[0049] Specifically, such as Figure 5 and Figure 6As shown, the cleaning mechanism 3 includes a cleaning tank 31, several cylinders 32, a cleaning roller brush module 33, and two sets of guide grooves 35. The cleaning tank 31 is fixed inside the frame 1. Several cylinders 32 are fixed on the top of the cleaning tank 31 and are located on both sides of the cleaning roller brush module 33. The output ends of the cylinders 32 are fixedly connected to the cleaning roller brush module 33. The cleaning roller brush module 33 is located above the cleaning tank 31. Inlet and outlet are provided through the front and rear sides of the cleaning roller brush module 33 along the memory strip conveying direction. The positions of the inlet and outlet correspond to the positions of the guide grooves 267. Two sets of guide grooves 35 are provided inside the cleaning roller brush module 33. The positions of the guide grooves 35 correspond to the positions of the two sets of inlet and outlet. The cleaning roller brush module 33 is located near the sorting area. Air knives 34 are installed in the inlet and outlet of the unloading mechanism 4. A cover 36 is fixedly connected to the top of the cleaning roller brush module 33. The cleaning tank 31 is used to hold cleaning solvent. Cylinder 2 32 is used to drive the cleaning roller brush module 33 to rise and fall, so that the bottom of the cleaning roller brush module 33 is located in the cleaning tank 31 to clean the memory module, or to remove it from the cleaning tank 31 for loading and unloading the memory module. The cleaning roller brush module 33 is composed of multiple brushes arranged and installed. The brushes are connected to each other and are driven to rotate by a motor. One row of brushes is driven by two motors. The brushes can be rotated to brush off the residual adhesive on the surface of the memory module, or the memory module can be moved slowly by rotating the brushes. The air knife 34 uses high-pressure cleaning air to clean water stains and residues attached to the memory module.

[0050] It should be noted that the roller brush can be made of synthetic fibers, such as nylon PA, polypropylene, PBT, PET, PVC and other plastic filaments, as well as natural fibers, such as pig bristles, wool, horsehair, etc. A liquid level sensor is installed on the cleaning tank 31 to provide timely feedback after the cleaning solution is consumed. An ultrasonic module is also installed in the cleaning tank 31 for ultrasonic cleaning. This ultrasonic module is a standard module that can be purchased on the market and will not be described in detail here. The cleaning solution used in the cleaning tank 31 can be transparent liquid water, such as pure water, deionized water, distilled water and organic solvents.

[0051] Specifically, such as Figure 7As shown, the sorting and unloading mechanism 4 includes two sets of loading modules 41, two sets of unloading modules 42, four sets of transfer modules 43, a transverse transfer module 44, a sorting module 45, and two sets of vision inspection components 47. The loading modules 41, unloading modules 42, transfer modules 43, and transverse transfer modules 44 have the same structure and layout as the loading module 21, unloading module 22, transfer module 23, and transverse transfer module 27, respectively. The unloading basket 6 is placed in the loading module 41 and the unloading module 44. On 42 and the second transverse module 44, the feeding module 41, the unloading module 42, the four sets of transfer modules 43 and the second transverse module 44 convey the unloading basket 6 in the same way as the feeding module 21, the unloading module 22, the four sets of transfer modules 23 and the second transverse module 27 convey the feeding basket 5. The difference is that two sets of movable ports are respectively provided on the transverse seats on both sides of the second transverse module 44, and the positions of the two sets of movable ports correspond to the positions of the feeding module 41 and the unloading module 42, respectively.

[0052] Two sets of lifting modules 46 are fixedly connected to the bottom of the frame 1. The two sets of lifting modules 46 are located on the transverse seat of the transverse module 44, near the movable opening of the cleaning mechanism 3. The lifting module 46 adopts a structure in which the pallet is lifted and lowered by a motor screw. The lifting module 46 is used to drive the pallet to lift and lower within the movable opening.

[0053] Furthermore, such as Figures 8-12 As shown, the sorting module 45 is located above the transverse module 44. The sorting module 45 includes a single-axis moving seat 452, a movable plate 453, two sets of rotary clamping cylinders 454, and two sets of grippers 455. The top of the frame 1 is fixed with a support 451. The single-axis moving seat 452 is fixed on the top of the support 451. The movable plate 453 is set on the single-axis moving seat 452. The two sets of rotary clamping cylinders 454 are respectively set on both sides of the sorting module 45. The two sets of grippers 455 are respectively set on the two sets of rotary clamping cylinders 454. Each set of grippers 455 has two grippers. The grippers 455 correspond to the inlet and outlet positions of the cleaning roller brush module 33 near the sorting and unloading mechanism 4. The single-axis moving seat 452 is used to drive the single-axis moving seat 452 to move closer to or away from the cleaning mechanism 3. The rotary clamping cylinders 454 are used to drive the grippers 455 to clamp the memory stick and drive the grippers 455 to rotate.

[0054] Furthermore, such as Figures 9-12As shown, the gripper 455 is provided with two sets of sliding grooves 4551. The sliding grooves 4551 are provided with a pressure sensor 4552, a sliding plate 4553 and an airbag 4554. The two sides of the pressure sensor 4552 are fixedly connected to the gripper 455 and the airbag 4554 respectively. The other side of the airbag 4554 is fixedly connected to the sliding plate 4553. The sliding plate 4553 is slidably connected to the gripper 455. The airbag 4554 is connected to a dual-purpose air pump. The pressure sensor 4552 is used to detect the pressure changes inside the airbag 4554 caused by inflation and deflation.

[0055] Two sets of airbags 4555 are provided between the two sets of slide plates 4553 of the two sets of slide grooves 4551. The airbags 4555 are located at both ends of the slide plates 4553, and the airbags 4555 are connected to a dual-purpose air pump.

[0056] The gripper 455 is equipped with a suction port 4556, which is located between two sets of slide plates 4553. The suction port 4556 is connected to a dual-purpose air pump 3.

[0057] Furthermore, such as Figure 7 As shown, two sets of visual inspection components 47 and two sets of waste bins 48 are located on both sides of the sorting module 45. The waste bins 48 are fixed to the top of the frame 1. The visual inspection component 47 includes a camera 471, an aperture 472, and a detection module. The camera 471 is fixed to the top of the frame 1 using a support device. The aperture 472 is fixed to the side of the bracket 451. The field of view of the camera 471 is aimed at the area illuminated by the aperture 472. The detection module is connected to the camera 471 by signal. The aperture 472 is used to adjust the illumination angle. The camera 471 is used to photograph memory modules under different positions and illumination angles. The detection module is used to acquire the images captured by the camera 471, distinguish the type and model of the memory modules and their cleaning status, and control the sorting. The waste bins 48 are used to collect memory modules that do not meet the cleaning standards or have inconsistent models and specifications.

[0058] Specifically, such as Figure 7 As shown, the bottom of the material basket 6 is provided with a second movable opening 61, which is matched in position and size with the first movable opening.

[0059] In actual operation, the feeding module 2 41, unloading module 2 42, transfer module 2 43, and transverse transfer module 2 44 use the same method as the feeding module 1 21, unloading module 1 22, transfer module 1 23, and transverse transfer module 1 27 to transfer the unloading basket 6. The difference is that the feeding mechanism 2 transfers the feeding basket 5 filled with memory sticks and the empty feeding basket 5 after the memory sticks are unloaded, while the sorting and unloading mechanism 4 transfers the empty unloading basket 6 and the unloading basket 6 filled with memory sticks after sorting and loading.

[0060] The specific process of sorting and loading is as follows: After the cleaning mechanism 3 finishes cleaning, cylinder 2 32 drives the cleaning roller brush module 33 to rise, so that the inlet and outlet of the cleaning roller brush module 33 correspond to the position of the gripper 455. Then, the single-axis moving seat 1 452 starts, driving the movable plate 2 453 to move closer to the cleaning mechanism 3. The rotary clamping cylinder 454 starts to rotate, so that the two sets of grippers 455 are in a vertical state, and the memory module is located between the two sets of sliding plates 4553. Then, the rotary clamping cylinder 454 is controlled to drive the two sets of grippers 455 to move closer to each other to clamp the two sides of the memory module, and the memory module that has been cleaned by the cleaning mechanism 3 is taken out.

[0061] During the clamping process of the gripper 455, the dual-purpose air pump 1 is started to inflate the airbag 4554, causing the airbag 4554 to bulge. The inflated airbag 4554 pushes the slide plate 4553, thereby causing the two sets of slide plates 4553 to move closer to each other and clamp the sides of the memory module. At the same time, the dual-purpose air pump 2 is started to inflate the airbag 4555, causing the airbag 4555 to bulge and fill the gaps at both ends of the two sets of airbags 4554. This creates a closed space between the memory module, the two sets of airbags 4554, the two sets of airbags 4555, and the gripper 455. Then, the dual-purpose air pump 3 is started to extract the air from the closed space, creating a negative pressure state. The negative pressure state can further ensure that the slide plate 4553 can fit against the sides of the memory module, improving the clamping effect of the slide plate 4553. It can also directly use the negative pressure to adsorb the sides of the memory module, reducing the contact area between the sides of the memory module and the gripper 455.

[0062] Pressure sensor 4552 detects the pressure change when the memory module is clamped by airbag 4554 and squeezed by airbag 4554. If there is a pressure change before and after the dual-purpose air pump 3 pumps air, it means that the memory module, the two sets of airbags 4554, the two sets of airbags 4555 and the clamp 455 form a closed space. If there is no pressure change, it means that there is a leakage point, the closed space is not formed, and there is a risk that the memory module will slip out.

[0063] After the gripper 455 clamps the memory module, the single-axis moving base 452 drives the movable plate 453 to move away from the cleaning mechanism 3. When passing the aperture 472, the speed slows down. The aperture 472 is controlled to adjust the light source at different angles. The camera 471 captures the image and sends it back to the detection module. The detection module quickly distinguishes the type, model, and cleaning status of the memory module according to internally set detection standards. For memory modules of uniform model and cleanliness, the single-axis moving base 452 drives the movable plate 453 to continue moving away from the cleaning mechanism 3 until the gripper 455 is above the lifting module 46, at which point it stops. At this point, the lifting module 46 drives the tray to rise, causing the... The lifting module 46's pallet passes through movable opening 1 and movable opening 2 61, and rises to the height of the unloading basket 6 to support the memory module. Then, the rotary clamping cylinder 454 rotates 90° clockwise, and the gripper 455 releases its grip on the memory module. After that, the lifting module 46 drives the pallet to gradually descend according to the thickness of the memory module. For memory modules with inconsistent models or that have not been cleaned properly, the single-axis moving seat 1 452 drives the movable plate 2 453 to continue moving away from the cleaning mechanism 3 until the gripper 455 is above the waste box 48 and stops. Then, the rotary clamping cylinder 454 rotates 90° clockwise, and the gripper 455 releases its grip on the memory module, which slides into the waste box 48.

[0064] It should be noted that when using the dual-purpose air pump 2 to inflate airbag 2 4555, the air pressure inside airbag 2 4555 is less than the air pressure inflated by the dual-purpose air pump 1 airbag 4554; anti-slip strips are provided on the side of the two sets of sliding plates 4553 that are close to each other to further prevent the memory stick from sliding; dual-purpose air pump 1, dual-purpose air pump 2, and dual-purpose air pump 3 are air pumps that can be used for both inflation and deflation; the pressure data changes detected by pressure sensor 4552 can be used to control the dual-purpose air pump 1 airbag 4554 to deflate or restart in a timely manner to ensure that the sliding plate 4553 holds the memory stick with stable force.

[0065] Workflow of sorting equipment for cleaning residual adhesive from memory modules:

[0066] Step 1: The operator places the loading basket 5 filled with memory modules to be cleaned onto the loading module 21. The equipment is started, and the loading module 21 and the transfer module 23 work together to move the frontmost loading basket 5 onto the transverse transfer seat of the transverse transfer module 27.

[0067] Step 2: The material basket lifting module 24 adsorbs and lifts the loading basket 5, and the pushing module 25 moves to push the memory modules one by one horizontally into the feeding module 26. The feeding module 26 rotates the flip plate 266, causing the memory modules to flip from a horizontal state to a vertical state by their own gravity and fall into the guide groove 267.

[0068] Step 3: The single-axis moving seat 262 of the feeding module 26 drives the pusher plate 268 to push the vertical memory bar along the guide groove 1 267, through the guide groove 2 35, and finally into the guide groove 2 35 of the cleaning roller brush module 33.

[0069] Step 4: Cylinder 2 32 drives the cleaning roller brush module 33 to descend, immersing the memory module in the solution of the cleaning tank 31. The roller brush rotates to brush the memory module to remove residual adhesive, while simultaneously moving the memory module slowly towards the outlet. After cleaning, the module rises, and the air knife 34 blows the memory module to remove residual liquid.

[0070] Step 5: The gripper 455 of the sorting module 45 moves to the cleaning outlet and picks up the memory module. The single-axis moving seat 452 drives the gripper 455 holding the memory module to pass through the vision inspection component 47. The camera 471 takes a picture, and the inspection module determines the model and cleanliness of the memory module.

[0071] Step Six: Sorting is carried out according to the test results. Qualified memory modules are transferred to the top of the unloading basket 6, the gripper 455 rotates and releases, and the memory modules fall into the tray of the lifting module 46 in the unloading basket 6 and are stacked in order. Qualified memory modules are transferred to the top of the waste box 48 and released for disposal.

[0072] Step 7: The empty loading basket 5, after the memory module transfer is completed, is lowered by the basket lifting module 24 and then transferred to the unloading end via the horizontal moving module 27 and the material transfer module 23, waiting for the operator to retrieve it. At the same time, the full unloading basket 6 is moved out, and the empty unloading basket 6 is automatically transported to the lifting module 46 position to prepare for the next cycle.

[0073] The above methods can significantly improve operational efficiency and production capacity. By utilizing flexible clamping technology, composite cleaning processes, and intelligent detection and sorting systems, efficient and accurate sorting can be achieved while increasing speed, and the safety of products during the processing and the quality of the final output can be strictly guaranteed.
