Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0054] Please see Figure 1 and Figure 2 As shown, the box-opening device of this application embodiment includes a box-opening platform 22, a fixing component, a cutting component 26, a pressure plate component 27, and a push plate component 23.

[0055] The unpacking platform 22 is used to place the box 201.

[0056] The fixing component is used to fix the box 201 onto the unpacking platform 22.

[0057] The cutting assembly 26 includes two sets of cutting blades, which are located on both sides of the unpacking platform 22. They are used to cut the two opposite end faces of the box 201, causing the two end faces of the box 201 to spread outward relative to the body of the box 201.

[0058] The pressure plate assembly 27 includes two sets of pressure plates, which are used to press the spread-out end faces so that the box 201 forms an opening at the end face.

[0059] The push plate assembly 23 includes a push plate 232, which is inserted into one opening of the box 201 and exits through another opening to push the contents of the box 201 out of the box 201.

[0060] like Figure 3 As shown, in this embodiment, the box 201 containing the lens 202 is a paper box 201 with a square or rectangular cross-section. Inside the box 201, there is a protective shell 203 made of paper or plastic (e.g., Figure 4As shown), the protective shell 203 has a groove for placing the lens 202. The two opposite end faces of the box 201 are either insert-type or one-end adhesive-type sealed. When the two end faces are cut near the upper part (as shown by the dotted line L), the sealing connection structure of the two end faces of the box 201 will fail, and the upper part of the two end faces will spread outwards (in the direction of arrow B) after losing connection with the box 201. To facilitate material conveying, such as... Figure 5 As shown, in this embodiment, box 201 is placed on tray 200. Tray 200 has a tray identification code, and box 201 has a box identification code. After box 201 is placed on tray 200, the identification code of box 201 needs to correspond with the identification code of tray 200 to enable traceability of the product manufacturing process. Simultaneously, to facilitate the removal of protective shell 203, box 201 should be placed with the side of protective shell 203 with the groove facing down in its upright position. When box 201 is in its upright position, when the lens 202 and protective shell 203 inside box 201 are pushed out, lens 202 is at the bottom and protective shell 203 is at the top, facilitating the removal of protective shell 203 by the equipment. The identification code of box 201 can be set on the upper surface of box 201 when it is upright, and the presence or absence of the identification code on the surface of box 201 can be used to determine the orientation of box 201. Meanwhile, an identification code can also be set on the bottom surface of the protective shell 203 (that is, the top of the protective shell 203 when the box 201 is placed upright). The identification code of the protective shell 203 and the identification code of the box 201 can be set to correspond to each other, or they can be set to be the same identification code for subsequent traceability of the lens 202.

[0061] like Figure 1 and Figure 6As shown, specifically, the box-unpacking device of this embodiment includes a frame 1, on which a worktable 10 is mounted. A box-unpacking platform 22 is mounted on the worktable 10. A fixing component is located above the box-unpacking platform 22 and is fixed to the inner side of the box-unpacking platform 22 (the side closest to the material conveyor belt 11) on the worktable 10. The fixing component is a telescopic structure; when it is necessary to fix the box 201 on the box-unpacking platform 22, it extends towards the box-unpacking platform 22 and applies pressure to the top and / or side of the box 201 to prevent the box 201 from moving during cutting, thus fixing the box 201 to the box-unpacking platform 22. The fixing component can move vertically and horizontally to press the box 201 or release the box 201 and exit the space above the box 201. When a new box 201 needs to be placed on the unpacking platform 22 or a used box 201 needs to be removed, the fixing component can be controlled to retract away from the unpacking platform 22, so as to create space above the unpacking platform 22 for placing and removing boxes and avoid interference with other components. Specifically, for example, the extension and retraction of the fixing component can be controlled by setting a telescopic cylinder that extends and retracts in the horizontal direction, and the pressure on the box 201 can also be controlled and fixed by setting a telescopic cylinder that extends and retracts in the vertical and / or horizontal directions.

[0062] like Figure 7 As shown, the cutter assembly 26 in this embodiment includes two sets of cutters. The cutters are disc-shaped and can rotate 360° to cut. The two sets of cutters are located on both sides of the box-opening platform 22, that is, on the outside of the two end faces of the box 201 that are to be cut to form an opening.

[0063] The unpacking device in this embodiment also includes a linear motion mechanism and two connecting plates. The linear motion mechanism is used to simultaneously drive the cutter assembly 26 and the pressure plate assembly 27 to move toward or away from the unpacking platform 22.

[0064] Each connecting plate is provided with a set of pressure plates and a set of cutters. The two connecting plates are respectively arranged side by side on the linear motion mechanism via linear motion device 283. The linear motion device 283 is used to drive the two connecting plates to move along the motion direction of push plate 232 on the linear motion mechanism.

[0065] The cutter assembly 26 also includes a cutter height adjustment drive device, which is used to drive the cutter to move up and down in the vertical direction on the connecting plate.

[0066] The pressure plate assembly 27 also includes a pressure plate height adjustment drive device 273, which is used to drive the pressure plate to move up and down in the vertical direction on the connecting plate.

[0067] That is, the cutter assembly 26 and the pressure plate assembly 27 are fixed on the same motion mechanism 28. This motion mechanism 28 can drive the cutter assembly 26 and the pressure plate assembly 27 to move together in a horizontal direction, moving towards or away from the box-opening platform 22. This motion mechanism 28 can be a linear motion mechanism 28, such as a synchronous belt or a linear module. Simultaneously, the cutter assembly 26 also includes a cutter height adjustment drive device. This cutter height adjustment drive device can simultaneously drive two sets of cutters to move up and down, or each set of cutters can be equipped with a separate cutter height adjustment drive device, each used to drive the corresponding cutter to move up and down. The cutter height adjustment can be automatic, semi-automatic, or manual. For example, the height of the box 201 on the box-opening platform 22 can be detected by a distance sensor or other detection device, and the height detection result can be sent to the controller. The controller presets the cutting height of the cutter based on the height of the box 201 and controls the corresponding cutter height adjustment drive device to drive the cutter to the required height, thus achieving automatic adjustment of the cutter height to meet the cutting needs of boxes 201 of different heights. Alternatively, the height of the cutter can be adjusted manually or automatically based on manual measurement or known height data of the box 201. For manual adjustment, the cutter can be detachably connected to the motion mechanism 28 via bolts or other connectors. The connection position of the bolts can be adjusted up and down, and manually adjusting the connection position of the bolts changes the connection height of the cutter to adapt to the cutting height requirements of the box 201. Alternatively, the heights of various boxes 201 can be statistically analyzed, and a cutting height can be set for each specification of box 201. The specification of the box 201 can be selected by the controller, and the controller controls the cutter height adjustment drive to automatically adjust the height of the cutter.

[0068] The pressure plate assembly 27 in this embodiment includes two sets of pressure plates. Both the pressure plate assembly 27 and the cutter assembly 26 are connected to the motion mechanism 28 via connecting plates. The first connecting plate is connected to the first cutter 261 and the first pressure plate 271, respectively, and the second connecting plate is connected to the second cutter 262 and the second pressure plate 272, respectively. The connecting plate is L-shaped and includes a horizontal plate 281 and a vertical plate 282. The cutter is connected to the lower surface of the horizontal plate 281, and the pressure plate is connected to the outer side of the vertical plate 282. The two horizontal plates 281 are arranged in parallel and are connected to the drive end of the motion mechanism 28 via a linear motion device 283 (horizontal spacing adjustment drive device). The motion mechanism 28 is used to drive the pressure plate and the cutter to move horizontally towards or away from the unpacking platform 22. The linear motion device 283 connected to the horizontal plate 281 is used to drive the corresponding connecting plate to move horizontally along the through direction of the opening of the box 201 to adjust the position of the pressure plate or the cutter so that it corresponds to the position of the two sides of the box 201. That is, the linear motion device 283 and the motion mechanism 28 move in the same horizontal direction, but their directions are perpendicular to each other. For example, if the linear motion device 283 moves along the length of the box 201, then the motion mechanism 28 moves along the width of the box 201. The cutter height adjustment drive device and the pressure plate height adjustment drive device 273 move along the height of the box 201. The pressure plate is fixed to the outer surface of the vertical plate 282 by the pressure plate height adjustment drive device 273, which is used to adjust the lifting height of the pressure plate to achieve different functions. For example, after the cutter finishes cutting the box 201, the two sides of the box 201 radiate outwards, but are not fully opened to form an opening. At this time, the pressure plate needs to rise above the upper surface of the box 201 and press down on the two end faces to form a through channel at both ends of the box 201. When the pressure plate is pressed down until the upper surface of the pressure plate is basically flush with or slightly lower than the upper surface of the box-opening platform 22, the pressure plate stops pressing down. Preferably, the upper surface of the pressure plate can be slightly lower than the unpacking platform 22 to avoid the push plate 232 colliding with the edge of the pressure plate when pushing the lens 202 outward, thus preventing the lens 202 from being pushed out normally. During the process of pressing the sides of the box 201 downward, a certain distance can be maintained between the two pressure plates and the unpacking platform 22 to ensure that the two sides of the box 201 can be pressed down smoothly.

[0069] When the cutter cuts the box 201, it can proceed from the inside out. That is, when two sets of box-opening devices 2 are installed, the cutters on both sides cut from the center of the worktable 10 outwards. In this way, when the cutter finishes cutting and retracts, it can drive the pressure plate back to the working position above the box 201, which helps to improve work efficiency. The cutting position of the cutter is at the top of the box 201 so that the pressure plate can press down the opened end face.

[0070] like Figure 2 As shown, the pusher assembly 23 in this embodiment includes a pusher drive device 231 and a pusher 232. The pusher drive device 231 drives the pusher 232 to move towards or away from the unpacking platform 22. The lower surface of the pusher 232 needs to be slightly higher than the upper surface of the unpacking platform 22. The pusher drive device 231 can be, for example, a linear motion mechanism such as a linear module.

[0071] like Figure 2 and Figure 6 As shown, to facilitate the collection of dismantled waste boxes 201, a waste box conveying channel 21 can be provided. The dismantling platform 22 is located on the workbench 10, and the waste box conveying channel 21 is located below the workbench 10. The waste box conveying channel 21 includes a waste box inlet 212 and a waste box outlet 211. The waste box inlet 212 is located below the dismantling platform 22, and the waste box outlet 211 is located on the side wall of the frame 1 below the workbench 10. A waste box 201 conveying assembly is provided between the waste box inlet 212 and the waste box outlet 211. The waste box 201 conveying assembly is used to output the waste boxes 201 that enter the waste box conveying channel 21 from the waste box inlet 212 to the outside of the waste box conveying channel 21 through the waste box outlet 211. The waste box 201 conveying assembly can be, for example, a conveyor belt or similar device.

[0072] To increase the collection efficiency of waste boxes 201 and reduce manual operation, a rotating tilting device (not shown) can be installed. The rotating tilting device is used to make the waste boxes 201 on the unpacking platform 22 fall into the waste box inlet 212. For example, the drive end of the rotating tilting device is connected to the side wall of the unpacking platform 22. The rotating tilting device drives the unpacking platform 22 to rotate vertically, so that the boxes 201 on the unpacking platform 22 (at this time, the fixing component releases the boxes 201) fall into the waste box inlet 212 below. The rotating tilting device can be, for example, a rotary cylinder. The specific structural type of the rotating tilting device is not limited, as long as it can make the unpacking platform 22 flip so that the waste boxes 201 fall into the waste box inlet 212.

[0073] like Figure 1 and Figure 6 As shown in the figure, this application embodiment also provides a lens unpacking device, including the box unpacking device of the above embodiment, and also includes a protective shell unpacking device 3. The protective shell unpacking device 3 includes a protective shell unpacking platform 32, a protective shell unpacking robot 33, and a protective shell conveying channel 31.

[0074] The protective shell removal platform 32 is located downstream of the box removal platform 22. The push plate 232 is used to push the lens 202 inside the box 201 and the protective shell 203 covering the lens 202 together to the protective shell platform outside the box 201.

[0075] The protective shell removal robot 33 is used to remove the protective shell 203 covering the lens 202 and transport it to the protective shell transport channel 31.

[0076] The protective shell removal platform 32 is located at a station downstream of the box removal platform 22. The push plate assembly 23 is used to push the lens 202 out of the box 201 and onto the protective shell removal platform 32 through the opening of the box 201. Similarly, one protective shell removal platform 32 can also be set on each side of the material conveyor belt 11.

[0077] The protective shell conveying channel 31 is located under the workbench 10 and includes a protective shell inlet 312 and a protective shell outlet 311. The protective shell inlet 312 is located on the workbench 10, and the protective shell outlet 311 is located on the side wall of the frame 1 under the workbench 10. A protective shell 203 conveying assembly is provided between the protective shell inlet 312 and the protective shell outlet 311. The protective shell 203 conveying assembly is used to output the protective shells 203 that enter the protective shell conveying channel 31 from the protective shell inlet 312 to the outside of the protective shell conveying channel 31. The structure of the protective shell conveying channel 31 is similar to that of the waste box conveying channel 21, and will not be described again.

[0078] The protective shell removal robot 33 is used to remove the protective shell 203 covering the lens 202 and put the protective shell 203 into the protective shell inlet 312.

[0079] The protective shell removal platform 32 and the case removal platform 22 are located on the same central axis. To facilitate the removal of the protective shell 203, a centering fixing component can be provided on the protective shell removal platform 32. This component ensures that the lens 202 and the protective shell 203, pushed by the push plate 232, are positioned in the center of the platform, facilitating the removal of the protective shell 203. The centering fixing component may include, for example, an adjusting centering mechanism and a suction fixing mechanism. The adjusting centering mechanism centers the protective shell 203 and the lens 202 using pushing or clamping methods. The suction fixing mechanism then suctions and fixes the lens 202, ensuring that the lens 202 will not move when the protective shell 203 is removed. When the lens 202 needs to be removed, the suction fixing mechanism can release its suction on the lens 202.

[0080] The protective case removal robot 33 can also grasp the protective case 203 using a gripper or suction function. After the protective case 203 is pushed out of the box 201, the identification code on the protective case 203 can be scanned by a scanning component located near the protective case removal platform 32. The protective case removal robot 33 can move back and forth between the protective case removal platform 32 and the protective case inlet 312.

[0081] like Figure 6As shown, the lens unpacking and packaging equipment of this application embodiment also includes a material conveyor belt 11 on the workbench 10, a tray sensor 12 and a tray barcode scanner 18 at the entrance of the material conveyor belt 11, and a first material blocking assembly 13, and may also include a controller.

[0082] The material conveyor belt 11 is used to convey the pallet 200, receiving the pallet 200 transferred from the previous process or directly receiving the pallet 200 containing the lens box 201, so as to transfer the pallet 200 to the next process. The conveying direction of the material conveyor belt 11 is the same as the pushing direction of the push plate 232.

[0083] The pallet sensor 12 is used to detect whether a pallet 200 has entered at the inlet of the material conveyor belt 11. The pallet sensor 12 can be, for example, a material presence or absence detection sensor, and can be installed at the inlet of the material conveyor belt 11. When a pallet 200 is detected entering at the inlet of the material conveyor belt 11, the detection result of the pallet 200 is sent to the controller, and the controller controls the first baffle assembly 13 to rise to prevent the pallet 200 from continuing to move forward.

[0084] The pallet scanner 18 is located on the workbench 10 near the first stop assembly 13 and is used to scan the identification code of the pallet 200 and send the scanning result to the controller.

[0085] The controller is used to control the first stop assembly 13 to rise after the pallet sensor 12 detects that a pallet 200 has entered the material conveyor belt 11, so as to block the pallet 200 from moving forward; and to control the first stop assembly 13 to descend after the pallet scanner 18 completes scanning the identification code of the pallet 200, so as to release the pallet 200.

[0086] The first baffle assembly 13 may be a baffle controlled by a drive device such as a lifting cylinder, hydraulic cylinder or electric cylinder.

[0087] like Figure 8 and Figure 9 As shown, to improve the efficiency of unpacking, a set of unpacking devices is symmetrically installed on the worktables 10 on both sides of the material conveyor belt 11. Each set of unpacking devices includes a box-opening device and a protective shell-opening device 3. The two sets of unpacking devices can work simultaneously, thereby improving the efficiency of unpacking. At this time, two boxes 201 containing lenses 202 can be placed in the same pallet 200 at the same time, so that the two boxes 201 can be transported at the same time, thereby further improving efficiency.

[0088] The equipment for removing lens packaging also includes a loading robot 14 and a second blocking component. The second blocking component is located at the waiting station, which is downstream of the station where the first blocking component 13 is located, and is used to block or release the tray 200; the loading robot 14 is used to place the box 201 on the tray 200 at the waiting station onto the unpacking platform 22.

[0089] For example, the station to be picked up can be the next station adjacent to the first blocking component 13. After the pallet scanner 18 completes scanning the pallet identification code, the controller controls the first blocking component 13 to descend, so that the pallet 200 continues to move forward to the station to be picked up under the drive of the material conveyor belt 11. At this time, the second blocking component rises to block the pallet 200 from moving forward.

[0090] The loading robot 14 can, for example, use grippers to pick up boxes 201 located in the tray 200, or it can use suction cups to pick up boxes 201. A fixed or movable distance sensor module can also be installed near the material-picking station or near the first material-blocking component 13. The distance sensor module can include a moving component for moving the distance sensor, and a distance sensor for detecting the relative position between the box 201 and the tray 200, sending the distance detection result to the controller. The controller then controls the loading robot 14 to move to a preset position to accurately pick up the box 201 based on the distance detection result. When a box-unpacking device 2 is installed on each side of the material conveyor belt 11, the same loading robot 14 can be used to load materials onto the box-unpacking platforms 22 on both sides sequentially.

[0091] The lens unpacking equipment also includes a feeding robot 15 and a third feed assembly.

[0092] The third blocking component is located at the unloading station, which is downstream of the picking station, and is used to block or release the pallet 200. After the pallet 200 is released by the second blocking component at the picking station, it arrives at the downstream unloading station, where the third blocking component blocks it.

[0093] The unloading robot 15 is used to move the lens 202 on the protective shell removal platform 32 into the tray 200 on the unloading station, such as... Figure 11 The tray 200 contains the lens 202. Two protective shell removal platforms 32 share a single unloading robot 15.

[0094] The loading robot 14 and the unloading robot 15 are respectively mounted above the material conveyor belt 11, with the loading robot 14 positioned closer to the unpacking device. The two unpacking devices share the loading robot 14 and the unloading robot 15.

[0095] When a box-unpacking device 2 is provided on each side of the material conveyor belt 11, a waste box inlet 212 can be provided below each box-unpacking platform 22. That is, the same waste box conveying channel 21 includes two waste box inlets 212 and one waste box outlet 211. Regardless of which waste box 201 enters the waste box conveying channel 21 through which waste box inlet 212, it is conveyed out through the same waste box outlet 211. The waste box outlet 211 can be connected to a waste box 201 processing device or a collection device for quick processing of waste boxes 201. The structure of the protective shell conveying channel 31 is similar to that of the material conveyor belt 11. When two protective shell unpacking devices 3 are provided, two protective shell unpacking platforms 32 and two protective shell inlets 312 are provided accordingly. The two protective shell inlets 312 share the same protective shell outlet 311.

[0096] like Figure 8 and Figure 10As shown, the lens unpacking equipment also includes a box transfer platform 24. The loading robot 14 is also used to place the box 201 on the tray 200 at the waiting station onto the box transfer platform 24. The box transfer platform 24 is equipped with a flipping component 25, which is used to flip the box 201 on the transfer platform by 180°. Because the box 201 may be placed upside down when it is placed in the tray 200, that is, when the box 201 is placed upside down, that is, the grooved surface of the protective shell 203 of the lens 202 is facing upwards, the lens 202 is located in the groove. If the lens 202 and the protective shell 203 are pushed out of the box 201 together in this state, the protective shell 203 cannot be automatically removed by the equipment. Therefore, a box unpacking device 2 is set up to realize the automatic operation of flipping the box 201. By scanning the upper surface of the box, it can be determined whether the box 201 is placed upside down by checking for an identification code. An upside-down box 201 needs to be first placed on the box transfer platform 24 by the loading robot 14 for flipping before being placed on the unpacking platform 22. Specifically, the flipping assembly 25 may include two clamping plates 251, a flipping drive device 252, and a lifting drive device 253. The two clamping plates 251 are connected to the driving ends of the clamping drive device and the flipping drive device 252, respectively. The fixed end (non-driving end) of the flipping drive device 252 is connected to the driving end of the lifting drive device 253. The clamping drive device may be, for example, two drive rods of a cylinder, each fixedly connected to a corresponding clamping plate 251. The clamping drive device drives the two clamping plates 251 to move away from or towards each other, thereby loosening or clamping the box 201 on the box transfer platform 24. The flipping drive device 252 is used to simultaneously drive the two clamping plates 251 to flip 180° vertically. The flipping drive device 252 can be, for example, a rotary cylinder. The lifting drive device 253 is used to drive the two clamping plates 251 to lift vertically, so that the clamping plates 251 do not interfere with the box transfer platform 24 below when clamping and flipping the box 201. For example, when it is necessary to flip the box 201, the clamping drive device can first adjust the distance between the two clamping plates 251 to clamp the box 201, and then the lifting drive device 253 can drive the clamping plates 251 and the box 201 to rise to a certain height. Finally, the flipping drive device 252 can drive the box 201 to flip 180°, and the lifting drive device 253 can drive the clamping plates 251 and the box 201 to descend. After the box 201 reaches the box transfer platform 24, the clamping drive device releases the box 201, and the loading robot 14 takes the box 201 and places it on the unpacking platform 22.

[0097] The lens unpacking equipment in this embodiment also includes a first unloading conveyor assembly 16 and a second unloading conveyor assembly 17 located at the outlet end of the material conveyor belt 11. The controller is also used to cause the tray 200 on the unloading station to be conveyed out by the first unloading conveyor assembly 16 or by the second unloading conveyor assembly 17. The first unloading conveyor assembly 16 is used to convey the correct tray 200, which means that the identification code of the tray 200 matches the identification code of the lens 202; the second unloading conveyor assembly 17 is used to convey the incorrect tray 200, which means that the identification code of the tray 200 does not match the identification code of the lens 202. The identification code of the tray 200 is obtained by scanning the tray barcode scanner 18, and the identification code of the lens 202 is obtained by scanning the identification code on the protective shell 203 by the scanning assembly.

[0098] The working steps of the lens unpacking device in this embodiment are as follows:

[0099] S1. Provide a pallet 200 containing materials and load the materials.

[0100] This material refers to the box 201 containing the lens 202. Depending on the actual needs of the equipment, the number of boxes 201 placed in the tray 200 can be two. Furthermore, to facilitate subsequent product traceability, the identification code of the tray 200 can be matched with the identification codes of the two boxes 201. For example, the identification code of a certain tray 200 can be defined as tray 1, the identification code of the box 201 placed in the first position of tray 1 can be defined as box 1, and the identification code of the box 201 placed in the second position can be defined as box 2. There is a one-to-one correspondence between box 1 and tray 1, including the position of box 1 within tray 200; similarly, the same applies to box 2 and tray 1. If the box 201 also includes a protective shell 203 for the lens 202, the identification code of the protective shell 203 can be scanned to match the identification code of the corresponding box 201. This ensures that when the lens 202 is finally unpacked and placed back into the tray 200, the lens 202 and the tray 200 are still matched, preventing material confusion.

[0101] The tray 200 can be transferred from the production line of the previous process to the equipment for removing lens packaging in this embodiment, or placed on the material conveyor belt 11 of the equipment in this embodiment in other manual or automatic ways.

[0102] S2, Identification detection.

[0103] The pallet sensor 12 detects that a pallet 200 has entered the material conveyor belt 11 and sends the detection result of the pallet 200 to the controller. The controller controls the first material blocking component 13 to rise and prevent the pallet 200 from continuing to move forward.

[0104] The pallet scanner 18 scans the identification code of the pallet 200 and sends the scanning result to the controller;

[0105] The controller controls the first baffle assembly 13 to descend, and the controller controls the second baffle assembly to rise.

[0106] S3, material loading robot 14 picks up materials.

[0107] The tray 200 continues to move forward and is intercepted at the waiting station by the second material blocking component; the distance sensor module detects the positional relationship between the two boxes 201 and the tray 200 respectively; the scanning device scans the upper surface of the box 201. If the identification code of the box 201 is scanned, it means that the box 201 is placed in the correct position, otherwise it is placed in the reverse position.

[0108] The controller controls the loading robot 14 to grab the corresponding box 201 according to the positional relationship between the box 201 and the tray 200. When the box 201 is placed upright, the loading robot 14 places the box 201 on the unpacking platform 22. If the box 201 is placed in reverse, the loading robot 14 places the box 201 on the box transfer platform 24, flips it over, and then places it on another unpacking platform 22.

[0109] The second stop assembly descends, the third stop assembly rises, and the pallet 200 continues to move forward but is intercepted by the third stop assembly at the unloading station.

[0110] S4. Remove box 201.

[0111] After box 201 is placed on unpacking platform 22, the fixing component extends and fixes box 201 to unpacking platform 22.

[0112] Two sets of cutters horizontally cut the upper part of the two sides of the box 201 from the inside to the outside (from the direction close to the material conveyor belt 11 to the direction away from the material conveyor belt 11). After cutting, the two sides of the box 201 spread outwards and the cutters retract.

[0113] The two pressure plates rise above the two sides of the box 201, move downwards and press the two sides of the box 201 below the surface of the unpacking platform 22, so that openings are formed on both sides of the box 201, until the upper surface of the pressure plates is level with or slightly lower than the upper surface of the unpacking platform 22, at which point the pressure plates stop moving.

[0114] The push plate 232 moves toward the opening of the box 201 and enters the box 201, pushing the lens 202 and the protective shell 203 covering the lens 202 to the protective shell removal platform 32.

[0115] The tilting component drives the unpacking platform 22 to rotate, causing the waste box 201 to enter the waste box inlet 212 and be discharged from the waste box outlet 211.

[0116] S5. Remove the protective shell 203 and then unload the material.

[0117] The identification code on the protective shell 203 is scanned to determine if it matches the identification code on the tray 200.

[0118] After the protective shell removal robot 33 grabs the protective shell 203, it puts it into the protective shell inlet 312, and the protective shell 203 transports the components out of the equipment from the protective shell outlet 311.

[0119] The unloading robot 15 picks up the unpacked lenses 202 and places them on the trays 200 at the unloading station.

[0120] The controller determines whether the identification codes of tray 200 and lens 202 match. If they match, the controller controls tray 200 to be output by the first unloading conveyor component 16. If they do not match, the controller controls tray 200 to be output by the second unloading conveyor component 17.

[0121] The box-opening device and lens unpacking equipment provided in this application can effectively improve the efficiency of removing lens packaging, greatly reduce the workload of manual operation, reduce production costs, and improve the automation level of unpacking.
