Description

Technical Field

[0001] This invention relates to the field of LCD screen recycling technology, specifically to a dismantling device and method for recycling LCD screens. Background Technology

[0002] The LCD screen recycling dismantling line mainly dismantles waste computer LCD monitors, waste ATM LCD monitors, waste monitors (LCD type), waste mobile communication handsets, and waste telephones. Dismantling is carried out under negative pressure, primarily using automated dismantling with manual assistance. It employs an intelligent physical separation process, utilizing intelligent robots to first dismantle the circuit boards and send them to the circuit board processing line. Then, the frame bracket is removed, and the LCD panel is separated. During the operation, the integrity of the LCD panel and backlight tubes is maintained; the backlight tubes are placed in specialized, sealed containers for separate storage to prevent damage and secondary pollution. The dismantled metals and LCD panels are sorted, stored, and sold. The circuit boards are sent to the circuit board processing line for further processing, and the plastics are sent to the plastic crushing production line for further processing.

[0003] The patent application CN104923551B discloses a dismantling and sorting process for waste liquid crystal displays (LCDs). The process employs the following workstations from upstream to downstream: loading station, outer casing cutting station, outer casing opening and separation station, laser cutting station, outer shielding cover recycling and main control circuit board separation and recycling station, inner shielding cover separation and recycling station, and LCD panel control circuit board and LCD panel separation and recycling station. These workstations are connected by conveyor belts to achieve assembly line operation. All workstations and the entire conveyor belt are isolated from the outside by safety protective enclosures. This invention uses an automated solution to achieve the goal of rapid and appropriate separation and recycling of multiple internal components of the LCD. The invention utilizes multiple workstations working collaboratively to achieve fully automated dismantling and sorting of waste LCDs. This invention minimizes the harm to operators caused by noise, dust, and harmful metals during the dismantling process.

[0004] However, the above-mentioned prior art still has the following drawbacks:

[0005] 1. The disassembled frame, LCD screen and circuit board will be placed on the conveyor for further sorting and picking. After the disassembled debris and dust are removed, they will be processed again or stored directly. Because the disassembled parts are piled up on the conveyor and squeezed against each other, it is inconvenient to pick them up and affects the efficiency of sorting and processing.

[0006] 2. After the LCD screens and circuit boards are sorted by the robotic arm, the bezels are often left on the conveyor and then collected manually. In addition, the accumulated bezels on the conveyor table will also affect the conveying of the LCD screens and circuit boards. Summary of the Invention

[0007] This invention provides a dismantling device for recycling liquid crystal displays (LCDs), which solves the problem mentioned in the background art where dismantled frames, LCDs, and circuit boards are placed on a conveyor for further sorting, picking, and cleaning of dismantled debris and dust before secondary processing or direct storage. Because the dismantled components pile up on the conveyor, they are squeezed together, making picking inconvenient and affecting the efficiency of sorting. Furthermore, after the LCDs and circuit boards are sorted by a robotic arm, the frames often remain on the conveyor and are then collected manually. Additionally, the piled-up frames on the conveyor table also hinder the transport of the LCDs and circuit boards.

During the process of the shovel moving against the first conveyor table, it abuts against the protrusion and compresses the second spring, causing the push plate to move upward.

[0012] As an optional solution of the dismantling device for recycling liquid crystal displays according to the present invention, the vibration component includes a grooved wheel slidably connected to a first conveyor table, a connecting shaft passing through the grooved wheels, and an annular groove opened in the grooved wheel matching the conveyor belt.

[0013] As an optional solution of the dismantling device for recycling liquid crystal displays according to the present invention, the vibration component further includes a wave plate installed on the shovel plate, and top rods are symmetrically arranged on both sides of the groove wheel on the connecting shaft. The bottom end of the top rod is connected to a ball head, and the ball head and the wave plate are fitted together.

[0014] As an optional solution of the dismantling device for recycling liquid crystal displays according to the present invention, two sets of guide tubes are symmetrically installed on the first conveyor platform, and a lifting frame is slidably connected inside each of the two sets of guide tubes, and the lifting frame is installed at both ends of the connecting shaft.

[0015] As an optional embodiment of the liquid crystal display screen recycling dismantling device described in this invention, the following features are provided: a movable plate is provided inside the collection tank, one end of the movable plate is pinned to the discharge port of the collection tank via a pin shaft, a rotating shaft is rotatably mounted at the discharge port of the collection tank, a gear is mounted at one end of the rotating shaft, a rack is fixedly mounted on the outer wall of the collection frame, and the rack and gear mesh; a fixed plate is connected to the outer wall of the collection frame, a fixed seat is connected to the outer wall of the first conveyor table, a first spring is connected between the fixed plate and the fixed seat, a guide rod is connected to the bottom surface of the fixed plate, and the guide rod and the fixed seat are slidably connected.

[0016] As an optional solution of the dismantling device for recycling liquid crystal displays according to the present invention, wherein: the movable plate is connected to a traction rope by a fixing block at one end away from the pin shaft, the other end of the traction rope is fixedly wound around the surface of the rotating shaft, a roller is installed on the inner wall of the collection tank away from the pin shaft, and the traction rope is wound around the surface of the roller.

[0017] The present invention also includes a dismantling method, comprising a dismantling device for recycling liquid crystal displays, the steps of which are as follows:

[0018] Step 1: Place the disassembled frame, LCD screen, and circuit board onto the first conveyor table for conveying and sorting;

[0019] Step 2: Use a robotic arm to sort the LCD screens on the first conveyor to the second conveyor, and use the robotic arm to sort the circuit boards on the first conveyor to the third conveyor. The circuit boards are then transported to the solder melting machine via the third conveyor to melt the solder joints.

[0020] Step 3: The remaining frame and other dismantled debris on the first conveyor platform fall into the collection trough and collection frame respectively, and finally the dismantled debris in the collection trough also falls into the collection frame.

[0021] The present invention has the following beneficial effects:

[0022] 1. The dismantling device for recycling LCD screens includes at least three conveyor platforms, including a first conveyor platform, a second conveyor platform, and a third conveyor platform. The first conveyor platform vibrates and conveys the dismantled frame, LCD panel, and circuit board. The LCD panel and circuit board are sorted to the second and third conveyor platforms by a robotic arm. After entering the third conveyor platform, the circuit board is conveyed to a solder melting machine for heating to melt the solder joints. The heating system is automatically controlled by the system without manual intervention. The dismantled LCD screens are then sorted, resulting in a high degree of automation and reduced labor costs.

[0023] 2. The dismantling device for recycling LCD screens includes a pushing component, which comprises a cylinder and a shovel plate connected to the output shaft of the cylinder. When the cylinder is activated, the shovel plate moves on the first conveyor table, pushing the dismantled fragments into the collection trough. This promptly pushes the fallen dismantled fragments into the collection trough, preventing the dismantled fragments from accumulating on the first conveyor table, which would hinder the normal transport of the frame, LCD panel, and circuit board on the conveyor belt.

[0024] 3. The dismantling device for recycling LCD screens includes a vibration component, which includes a grooved wheel located below the conveyor belt. The shovel plate moves up and down, causing the grooved wheel to move up and down, which in turn causes the conveyor belt to vibrate. This not only loosens the dismantled parts stacked on the conveyor belt, but also shakes the dismantled fragments onto the first conveyor table. This allows the pushing component to push the fragments into the collection trough, enabling timely cleaning of the first conveyor table and preventing the accumulation of dismantled fragments from obstructing the conveying and sorting of other dismantled parts such as LCD screens and circuit boards.

[0025] 4. This dismantling device for recycling LCD screens features a movable plate. One end of the movable plate is pinned to a collection trough via a pin shaft, while the other end is connected to a traction rope via a fixed block. The floating of the collection frame drives the rack to move up and down, which in turn drives the gear to rotate. As the gear rotates, it drives the rotating shaft to wind up the traction rope, pulling the other end of the movable plate up and down, creating a swaying motion. This causes the collected material in the collection trough to be guided into the collection frame, preventing the recyclable material from accumulating in the collection trough.

[0037] 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.

[0038] Example 1, please refer to Figures 1 to 10 The present invention discloses a dismantling device for recycling liquid crystal displays, including a first conveyor platform 1, on which conveyor rollers 2 are rotatably mounted, and a conveyor belt 3 is driven to connect the conveyor rollers 2. One end of a set of conveyor rollers 2 is driven to connect a motor 4. A second conveyor platform 37 and a third conveyor platform 38 are respectively arranged on both sides of the first conveyor platform 1, and a solder melting machine 39 is arranged at the discharge port of the third conveyor platform 38.

[0039] In this embodiment, a first conveyor 1, a second conveyor 37, and a third conveyor 38 are respectively set up. The first conveyor 1 is used to transport the disassembled frame, LCD panel, and circuit board. During the transport process, the robot arm 40 sorts the LCD panel and circuit board to the second conveyor 37 and the third conveyor 38 respectively. After the circuit board enters the third conveyor 38, it is transported to the solder melting machine 39 for heating. The heating method is electromagnetic heating, and the heating temperature is controlled at about 220-245℃ to melt the solder joints. The heating system is automatically controlled by the system without manual intervention. After the disassembled LCD screen is sorted, the degree of automation is high and the labor consumption is reduced.

[0040] The aforementioned equipment is used to classify and collect molten tin, various components, heat-dissipating aluminum, and scrap iron / plastic, and after reaching a certain quantity, it is transported to the warehouse for storage.

[0041] Conveyor belt 3 is configured as a round belt that can be spliced;

[0042] It should be noted that the conveyor belt 3 is designed as a circular belt that can be connected. During the conveying process, incomplete components and dust from disassembly can fall through the gaps between the conveyor belts 3. The circular belt structure can reduce the contact area between the conveyor belt and the LCD panel and circuit board during the conveying process, thereby minimizing damage to the LCD panel and circuit board.

[0043] The first conveyor 1 is equipped with a collection frame 5 at the discharge end. The first conveyor 1 is provided with a dust suction port 13 and a filter screen 14 is installed inside the dust suction port 13. The bottom of the first conveyor 1 is provided with a suction pipe 15, which is connected to the dust suction port 13. A fan 16 is connected to the bottom of the suction pipe 15.

[0044] In this embodiment, a collection frame 5 is provided at the discharge end of the first conveyor table 1 to collect the disassembled frame and disassembled fragments. At the same time, since the disassembled components generate a lot of dust, a fan 16 is provided at the bottom of the first conveyor table 1. When the fan 16 is started, the dust is collected through the suction pipe 15 and the dust suction port 13. The air outlet of the fan 16 is connected to a dust collection bag to prevent dust from falling back.

[0045] Example 2 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 10 The first conveyor table 1 is symmetrically provided with a pushing assembly and a collecting trough 28. The pushing assembly includes three sets of cylinders 10. The output shaft ends of the three sets of cylinders 10 are connected to shovels 11. The shovels 11 are elastically attached to the upper surface of the first conveyor table 1. A slope is opened on one side of the shovels 11.

[0046] In this embodiment, considering that if the fallen dismantled fragments accumulate on the first conveyor table 1, it will be detrimental to the normal conveying of the frame, LCD panel and circuit board on the conveyor belt 3, a pushing component is provided, which includes a cylinder 10 and a shovel plate 11 connected to the output shaft end of the cylinder 10. The cylinder 10 is started to drive the shovel plate 11 to move on the first conveyor table 1, pushing the dismantled fragments into the collection trough 28.

[0047] It should be noted that the pushing surface of the shovel plate 11 has an inclined surface to prevent the debris from accumulating and overflowing on the rear side of the shovel plate 11 when pushing and dismantling the debris.

[0048] Example 3 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 10 The material pushing assembly also includes protrusions 12 arranged at equal intervals on the upper surface of the first conveyor table 1. A push plate 17 is installed at the output shaft end of the cylinder 10. A shovel plate 11 is slidably connected to one side of the push plate 17. A second spring 18 is connected between the push plate 17 and the shovel plate 11. During the movement of the shovel plate 11 against the first conveyor table 1, it abuts against the protrusions 12 and compresses the second spring 18, causing the push plate 17 to move upward.

[0049] In this embodiment, a protrusion 12 is provided on the upper surface of the first conveyor table 1. During the movement of the shovel plate 11, when the shovel plate 11 contacts the protrusion 12, it compresses the second spring 18, causing the shovel plate 11 to move up a certain height, with a height range of 2mm-4mm. This not only ensures that the disassembled scrap material is normally pushed out of the first conveyor table 1, but also prevents the shovel plate 11 from getting stuck during the pushing process.

[0050] It should be noted that, since a gap is generated between the shovel plate 11 and the first conveyor table 1 after the shovel plate 11 moves upward, some debris may be pushed to the side of the first conveyor table 1 away from the collection tank 28 during the resetting process of the shovel plate 11, but this does not affect the recycling of the dismantled body.

[0051] A vibration assembly is provided between the conveyor belt 3 and the first conveyor table 1. The pushing assembly is used to push the dismantled fragments shaken off by the vibration assembly into the collection trough 28 for collection.

[0052] Example 4 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 10 The vibration assembly includes a grooved wheel 20 slidably connected to the first conveyor table 1, a connecting shaft 19 passing through the grooved wheels 20, and an annular groove opened in the grooved wheel 20 matching the conveyor belt 3.

[0053] In this embodiment, a grooved wheel 20 is provided below the conveyor belt 3. Several sets of grooved wheels 20 are connected in series through the connecting shaft 19 and are all fitted close to the bottom of the conveyor belt 3. The up and down floating of the grooved wheels 20 causes the conveyor belt 3 to vibrate, which not only loosens the disassembled parts stacked on the conveyor belt 3, but also shakes the disassembled fragments onto the first conveyor table 1. This makes it easier for the aforementioned pushing component to push them into the collection trough 28, so as to clean the first conveyor table 1 in time and avoid the accumulation of disassembled fragments that may obstruct the conveying and sorting of other disassembled parts such as LCD screens and circuit boards.

[0054] The vibration assembly also includes a wave plate 22 mounted on the shovel plate 11, and top rods 23 symmetrically arranged on both sides of the groove wheel 20 on the connecting shaft 19. The bottom end of the top rod 23 is connected to a ball head 24, and the ball head 24 and the wave plate 22 are fitted together.

[0055] In this embodiment, after the cylinder 10 is started, the cylinder 10 drives the shovel plate 11 to move. The wave plate 22 is installed on the shovel plate 11, and the shovel plate 11 drives the wave plate 22 to move. The surface of the connecting shaft 19 is provided with a push rod 23 with a ball head 24. The push rod 23 floats up and down during the process of contacting the wave plate 22, thereby using the grooved wheel 20 to drive the conveyor belt 3 to vibrate.

[0056] Two sets of guide tubes 21 are symmetrically installed on the first conveyor table 1. Lifting frames 27 are slidably connected inside both sets of guide tubes 21. The lifting frames 27 are installed at both ends of the connecting shaft 19.

[0057] To ensure the stability of the vibrating structure, lifting frames 27 are provided at both ends of the connecting shaft 19, and the lifting frames 27 are slidably connected to the connecting shaft 19 on the first conveyor table 1.

[0058] A support plate 25 is provided on one side of the upper surface of the first conveyor table 1 at one end of the wave plate 22. A groove 26 is provided in the support plate 25. One end of the wave plate 22 is connected to the shovel plate 11, and the other end is slidably connected in the groove 26, which further provides stable support for the vibrating structure.

[0059] Example 5 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 10 The outer wall of the collection frame 5 is connected to a fixing plate 6, the outer wall of the first conveying table 1 is connected to a fixing seat 9, a first spring 7 is connected between the fixing plate 6 and the fixing seat 9, a guide rod 8 is connected to the bottom surface of the fixing plate 6, and the guide rod 8 and the fixing seat 9 are slidably connected.

[0060] In this embodiment, a buffer structure is provided between the collection frame 5 and the first conveying table 1. The buffer structure includes a fixed plate 6, a fixed seat 9, a first spring 7 and a guide rod 8. When the material falls into the collection frame 5, the inertia of gravity causes the first spring 7 to stretch. When the inertia disappears, the first spring 7 contracts, driving the collection frame 5 to reset. As a result, the collection frame 5 floats up and down, avoiding collisions between materials when they fall and ensuring the integrity of the recycled materials as much as possible.

[0061] Example 6 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 10 A movable plate 29 is provided inside the collection trough 28. One end of the movable plate 29 is pinned to the discharge port of the collection trough 28 via a pin 34. A rotating shaft 33 is rotatably installed at the discharge port of the collection trough 28. A gear 32 is installed at one end of the rotating shaft 33. A rack 31 is fixedly installed on the outer wall of the collection frame 5. The rack 31 and the gear 32 mesh. A traction rope 30 is connected to the end of the movable plate 29 away from the pin 34 via a fixing block 36. The other end of the traction rope 30 is fixedly wound around the surface of the rotating shaft 33. A roller 35 is installed on the inner wall of the collection trough 28 away from the pin 34. The traction rope 30 is wound around the surface of the roller 35.

[0062] In this embodiment, a movable plate 29 is provided in the collection trough 28. One end of the movable plate 29 is pinned to the collection trough 28 by a pin 34, and the other end is connected to a traction rope 30 by a fixing block 36. The floating of the collection frame 5 drives the rack 31 to move up and down. During this process, the gear 32 rotates. As the gear 32 rotates, it drives the rotating shaft 33 to wind up the traction rope 30, pulling the other end of the movable plate 29 up and down, generating a shaking motion, thereby pouring the collected material in the collection trough 28 into the collection frame 5, preventing the recyclable material from accumulating in the collection trough 28.

[0063] The present invention also provides a dismantling method, including a dismantling device for recycling liquid crystal displays, the steps of which are as follows:

[0064] Step 1: Place the disassembled frame, LCD screen and circuit board on the first conveyor table 1 for conveying and sorting;

[0065] Step 2: Use the robotic arm 40 to sort the LCD screens on the first conveyor table 1 to the second conveyor table 37, and use the robotic arm 40 to sort the circuit boards on the first conveyor table 1 to the third conveyor table 38. The circuit boards are then transported to the solder melting machine 39 via the third conveyor table 38 to melt the solder joints.

[0066] Step 3: The remaining frame and other dismantled debris on the first conveyor 1 fall into the collection trough 28 and the collection frame 5 respectively. Finally, the dismantled debris in the collection trough 28 also falls into the collection frame 5.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0068] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
