[0002] Affected by the workshop environment, machine environment, and material conditions, there is a certain probability of poor bonding during the bonding process of the display screen and the touch screen, such as bubbles and foreign matter between the display screen and the touch screen. To this end, we need to recycle the defective parts for secondary use to create their value, that is, disassemble the display screen and the touch screen and reassemble them. The current processing method is to use a large refrigerator to freeze at -100° for one hour to reduce the optical adhesion between the display screen and the touch screen, making it invalid, and then take out the product and disassemble it manually, but manual disassembly is slow and prone to damage.

Summary of the invention

[0008] By adopting the above technical solution, a circular conveying track is set on the workbench of the disassembling device, and the flexible component conveying trolley with the cover plate to be disassembled is installed on the conveying track. The conveying trolley flattens the flexible component from the loading area and installs it on the fixed component on it. The fixed component is installed toward the outside of the workbench. During installation, the cover plate is placed on the outside of the fixed component. After installation, the fixed component of the conveying trolley is rotated to allow multiple groups of conveying trolleys to be arranged on the conveying track of the loading area to wait for freezing and disassembly. The flexible component entering the freezing area is rotated on the conveying trolley through the fixed component toward the liquid nitrogen spraying device. The liquid nitrogen spraying device supplies liquid nitrogen through the liquid nitrogen tank, which is transported to the spray gun through the conveying hose. The spray gun sprays liquid nitrogen on the entire cover plate surface of the flexible component under the control of the three-axis manipulator for instant freezing. The flexible component sprayed with liquid nitrogen is loaded into the disassembly area through the conveying trolley. The separation robot arm in the disassembly area is fixedly installed on the top of the workbench. The gap between the cover plate and the main body of the flexible component is identified by the CCD cameras on both sides of the separation plate at its output end. The separation robot arm The driving cylinder drives the separation plate to move downward to realize the disassembly of the cover plate. The disassembled cover plate is adsorbed on the top side of the cover plate by the cover plate suction cup on the separation component, and the cover plate suction cup is driven to rise to the automatic storage component. The automatic storage component hangs the disassembled cover plates at intervals to meet the needs of continuous disassembly of the cover plates. The flexible component that has completed the disassembly of the cover plate enters the unloading area to unload it from the conveying trolley, and the conveying trolley continues to return to the loading area to load the flexible component of the cover plate to be disassembled, and this process is repeated to realize continuous and efficient cover disassembly operations of the flexible component.

[0009] Preferably, a fixing component fixes the flexible component in the loading area, and includes an adjusting box and telescopic cylinders distributed in a ring around the adjusting box, wherein an adsorption mechanism for fixing the flexible component is installed at the output end of the telescopic cylinder, and the adsorption mechanism includes a limiting right angle at the end corner and an adsorption plate on one side of the limiting right angle, wherein the limiting right angle is fitted with two adjacent side surfaces at the end corner of the flexible component, and a vacuum suction hole is provided on the adsorption plate for adsorbing the flexible component.

[0010] The adjusting box includes a box body and an adjusting mechanism annularly distributed inside the box body. The adjusting mechanism installs the telescopic cylinder through driven gears around it. The adjusting mechanism drives the driven gears to rotate so that the output end of the telescopic cylinder can correspond to the four vertex angles of the flexible component.

[0011] The adjustment mechanism includes two groups of first adjustment racks respectively arranged between two groups of driven gears on one side and second adjustment racks located between two groups of driven gears on the other side, wherein the first adjustment rack and the second adjustment rack adopt a U-shaped structure, and the openings of the two are opposite to each other, and the third adjustment rack is arranged on the inner side of the openings of the two, the third adjustment rack in the first adjustment rack and the second adjustment rack is located at the same position, and the inner sides of the openings of the two relatively arranged are also provided with adjustment gears, and an adjustment rod passes through the adjustment gear, and the two ends of the adjustment rod are respectively connected to the adjustment box for rotation.

[0012] By adopting the above technical solution, the adjustment box in the fixed component adjusts the angle of the telescopic cylinder around it through the adjustment mechanism provided therein, so that the output end of the telescopic cylinder can be aligned with the four vertex angles of the flexible component, and the adsorption component at its output end adsorbs and fixes the four vertex angles of the flexible component through the output shaft of the telescopic cylinder. The four groups of driven gears provided in the box body of the adjustment mechanism are fixed to the end of the telescopic cylinder, and the adjustment gear at the center of the box body is driven to rotate by the adjustment rod, and the adjustment gear is meshed and transmitted with the first adjustment rack and the third adjustment rack in the opening of the second adjustment rack that are relatively distributed. Since the positions of the third adjustment racks in the first adjustment rack and the second adjustment rack are the same, when the openings of the two are relatively distributed, the third adjustment rack is respectively located above and below the adjustment gear and meshed and transmitted respectively. Therefore, when the adjustment gear rotates, the first adjustment rack and the second adjustment rack are close to or away from each other, and the tooth surfaces on the first adjustment rack and the second adjustment rack are both located on the upper and lower surfaces of one end of the opening. When the first adjustment rack and the second adjustment rack move relative to each other, the tooth surfaces at the opening end can mesh and transmit with the two groups of driven gears on this side, thereby realizing the adjustment of the position of the hydraulic cylinder on this side. Because most flexible components are regular rectangular sheet structures, the adjustment structure can synchronously adjust the rotation angles of the hydraulic cylinders on both sides to achieve rapid positioning of flexible components of different sizes, improve the loading speed of flexible components, and thus improve the cover disassembly efficiency of the entire device.

[0013] Preferably, the automatic storage assembly includes several groups of horizontally distributed clamping plates, wherein the top of the clamping plate is connected to the movable seat through a telescopic rod, the telescopic rod includes a sleeve and a sleeve rod sleeved on the rod body, the sleeve is sleeved on the sleeve rod, and a retractable limiting protrusion is installed on the side of the sleeve rod, and the limiting protrusion is adapted to the limiting perforation on the inner side of the sleeve.

[0014] Two groups of driving blocks with inclined surfaces facing outward are provided on the top of the clamping plate, and a sliding plate is slidably installed at the bottom of the movable seat, wherein the sliding plate is installed with an inclined surface adapted to the top of the driving block. When the driving block rises, it can drive the sliding plate to move to both sides, and the outer end of the sliding plate is installed with a card block or a card slot adapted to the adjacent clamping plate, wherein the card block and the card slot are respectively located at the end portions of the sliding plate on both sides of the clamping plate.

[0015] A transmission rack is provided at the bottom of the sliding plate, and a transmission gear meshing with the transmission rack is installed at the bottom of the sliding plate, wherein the transmission gear is located at the bottom of the sliding plate, and both ends of the rotating shaft of the transmission gear extend out of the front and rear ends of the entire clamping plate, and a clamping plate is installed at the end of the rotating shaft, and the rotating shaft is fixedly installed at the bottom of the moving seat through a bearing seat, and a buffer layer is installed at the clamping end of the clamping plate, and the surface of the buffer layer is evenly distributed with protrusions.

[0016] An unlocking button is also installed on the top of the sleeve rod, and the unlocking button includes a pressing plate on the top and an unlocking rod on the bottom, wherein the bottom of the pressing plate is connected to the top of the sleeve rod through a spring, and the unlocking rod passes through the limiting protrusion, and the limiting protrusion is provided with an unlocking through hole, wherein the top opening of the unlocking through hole is larger than the bottom opening, and one side slope of the unlocking through hole extends from one side of the limiting protrusion close to the sleeve rod to the other side.

[0017] The top of the moving seat is slidably mounted on the discharging track, and a driving mechanism for driving the sliding plate to move is mounted on the top of the discharging track.

[0018] By adopting the above technical solution, after the cover plate is removed from the disassembly area, the cover plate suction cup absorbs the cover plate and lifts it, and the top of the cover plate is lifted up to press the plate, and the spring inside the sleeve in the telescopic rod pressing the top of the plate is squeezed, and the sleeve rod gradually enters the sleeve, and the limiting protrusion in the sleeve rod squeezes the spring inside it when entering the sleeve, until the limiting protrusion on the sleeve rod reaches the position of the limiting perforation on the sleeve and is acted upon by the spring to enter the limiting perforation, thereby realizing the locking of the sleeve rod and the sleeve. The camming plate is moved upward and downward to move between the two sliding plates, pushing the sliding plates to the sides. The movement of the sliding plates can separate the two adjacent moving seats that are not clamped, thereby avoiding adhesion between the cover plates. The sliding plates are slidably installed in the slide grooves on the bottom surface of the moving plates. The clamping blocks and the clamping grooves arranged on the outside of the sliding plates can ensure the stability of the relative position connection between the two adjacent moving plates. The transmission rack on the bottom surface of the sliding plates is meshed with the transmission gear for transmission. The rotation of the transmission gear drives the rotating shaft at its center to rotate, and the clamping plates at both ends of the rotating shaft are rotated from the top of the clamping plate to the openings on both sides of the clamping plate. The clamping plates can clamp the cover plates that are abutted against the bottom of the clamping plate from both sides to achieve clamping of the cover plates. The clamping state is locked by the connection between the above-mentioned sleeve rod and the sleeve. At this time, the cover plate suction cup can be removed for the adsorption and fixation of the next group of cover plates. The top of the sliding plate slides at the bottom of the discharge track, and the driving mechanism drives the sliding plate to move on the discharge track. After a group of cover plates are clamped at the bottom of a single sliding plate, it is pushed toward the outside of the workbench by a distance of the width of the sliding plate, thereby meeting the clamping and fixing requirements after the next group of cover plates are removed.

The top of the moving seat 8 is slidably installed on the discharge track 9, and the top of the discharge track 9 is installed with a driving mechanism 91 for driving the sliding plate 81 to move. After the cover plate is removed from the disassembly area, the cover plate suction cup 421 absorbs the cover plate and lifts it, and the top of the cover plate is lifted up and pressed against the plate 6. The spring inside the sleeve 71 in the telescopic rod 7 pressed against the top of the plate 6 is squeezed, and the sleeve rod 72 gradually enters the sleeve 71. The limiting protrusion 721 in the sleeve rod 72 squeezes the spring inside it when entering the sleeve 71, until the limiting protrusion 721 on the sleeve rod 72 reaches the position of the limiting perforation 711 on the sleeve 71 and is acted upon by the spring to enter the limiting perforation 711, thereby realizing the locking of the sleeve rod 72 and the sleeve 71.At the same time, the driving block 61 on the top of the clamping plate 6 moves up and down into between the two sliding plates 81, pushing the sliding plate 81 to both sides.
