[0001] This application relates to the technical field of glasses production equipment, and particularly to a device and method for removing lens packaging. Background Art

[0002] When lenses leave the factory or after the previous process is completed, in order to protect the lenses, the lenses are usually placed in a paper box, and a protective shell is provided in the box. There are grooves on the protective shell, and the lenses are placed in the grooves of the protective shell. During the production process of glasses, operations such as grinding and processing of the lenses are required. At this time, the lenses need to be taken out of the box and the packaging on the lenses needs to be removed. Currently, in the prior art during the production process of glasses, to remove the lens packaging, workers need to take down the tray containing the lens box from the production line, remove the lens box, take out the lenses from the lens box, remove the protective shell, and then put it back on the tray, and then put the tray back on the production line.

[0054] In the description of this application, it should be understood that the orientation or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this application. In the description of this application, unless otherwise stated, the meaning of "plurality" is two or more.

[0055] In the description of this application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0056] Please refer to Figures 1 to 3 , the device for removing the lens package in the embodiment of this application includes a box-opening mechanism 2, and the box-opening mechanism 2 includes a box-opening platform 22, a fixing component, a cutter component 26, a pressing plate component 27, and a pushing plate component 23.

[0057] The box-opening platform 22 is used for placing the box 201 containing the lens 202.

[0058] The fixing component is used for fixing the box 201 on the box-opening platform 22.

[0059] The cutter component 26 is used for cutting the upper parts of the sides of the box 201 on both sides of the box-opening platform 22 respectively.

[0060] The pressing plate component 27 is used for pressing down the two sides of the cut box 201 to form openings on the two sides of the box 201 respectively.

[0061] The pushing plate component 23 is used for pushing the lens 202 out of the box 201 through the opening.

[0062] As Figure 4As shown, the lens box 201 of this embodiment 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 (as Figure 7 shown). The protective shell 203 is provided with grooves for placing the lens 202. Two opposite end faces of the box 201 are of plug-in or pasted sealing. When cutting is performed at the position near the upper part of the two end faces (the position shown by the dashed line L), the sealing structure of the two end faces of the box 201 will fail, and the upper parts of the two end faces will spread outwards (the direction indicated by the arrow B) after losing the connection with the box 201. For the convenience of material transportation, as Figure 5 and Figure 6 shown, the box 201 of this embodiment is placed on the tray 200. The tray 200 is provided with a tray identification code, and the box 201 is provided with a box 201 identification code. After the box 201 is placed in the tray 200, it is necessary to make the identification code of the box 201 correspond to the identification code of the tray 200 in order to realize the traceability of the product production process. At the same time, in order to facilitate the removal of the protective shell 203, it is necessary to make the side of the protective shell 203 with grooves face down as the positive placement state of the box 201. When the box 201 is in the positive placement state, when the lens 202 and the protective shell 203 in the box 201 are pushed out, the lens 202 is below and the protective shell 203 is above, which is convenient for the device to remove the protective shell 203. The identification code of the box 201 can be set on the upper surface when the box 201 is placed positively, and the front and back of the box 201 can be judged by whether there is an identification code on the surface of the box 201. At the same time, 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 positively). The identification code of the protective shell 203 and the identification code of the box 201 can be set in a corresponding relationship, or directly set to the same identification code for subsequent traceability of the lens 202.

[0063] As Figure 1As shown, specifically, the device for removing the lens packaging in this embodiment includes a frame 1, and a workbench 10 is provided on the frame 1. A box-opening platform 22 is installed on the workbench 10. A fixing component is provided above the box-opening platform 22, and the fixing component is a telescopic structure. When it is necessary to fix the box 201 on the box-opening platform 22, it extends towards the box-opening platform 22 and presses on the top and / or side of the box 201 to prevent the box 201 from moving, so that the box 201 is fixed on the box-opening platform 22. When it is necessary to place a new box 201 or remove a waste box 201 on the box-opening platform 22, the fixing component can be controlled to retract in a direction away from the box-opening platform 22, so as to vacate a space for placing and taking above the box-opening platform 22 and avoid interference. Specifically, for example, the telescopic cylinder that expands and contracts in the horizontal direction can be set to control the expansion and contraction of the fixing component, and the telescopic cylinder that expands and contracts in the vertical direction and / or horizontal direction can also be set to control and realize the pressing and fixing of the box 201.

[0064] As Figure 8 and Figure 9As shown in the figure, the cutter assembly 26 of this embodiment includes two groups of cutters. The cutters are disc-shaped and can rotate 360° for cutting. The two groups of cutters are respectively located on both sides of the unpacking platform 22, that is, outside the two sides of the box 201 where the opening is to be cut. The cutter assembly 26 and the pressing plate assembly 27 are fixed on the same motion mechanism 28. The motion mechanism 28 can drive the cutter assembly 26 and the pressing plate assembly 27 to move together. The moving direction is horizontally close to or away from the unpacking platform 22. The motion mechanism 28 can be a linear motion mechanism 28 such as a synchronous belt or a linear module. At the same time, the cutter assembly 26 also includes a cutter height adjustment drive device. The cutter height adjustment drive device can drive the two groups of cutters to move up and down at the same time. Or, a cutter height adjustment drive device can be provided for each group of cutters, and each cutter height adjustment drive device is respectively used to drive the corresponding cutter to move up and down. For the adjustment of the cutter height, it can be automatic adjustment, or semi-automatic or manual adjustment. For example, a detection device such as a distance sensor can be used to detect the height of the box 201 on the unpacking platform 22, and send the height detection result to the controller. The controller presets the cutting height of the cutter according to the height of the box 201, and controls the cutter height adjustment drive device corresponding to the cutter to drive the cutter to move to the required height, realizing the automatic adjustment of the cutter height to meet the cutting requirements of boxes 201 with different heights. Or, the height of the cutter can be adjusted manually or automatically by manual measurement or according to the known height data of the box 201. For manual adjustment, for example, the cutter is detachably connected to the motion mechanism 28 through connectors such as bolts, and the connection position of the bolts can be adjusted up and down. Manually adjusting the connection position of the bolts changes the connection height of the cutter, so as to adapt to the cutting height requirements of the box 201. Or, the heights of various boxes 201 are statistically analyzed, and a cutting height is set for each specification of the box 201. By selecting the specification of the box 201 through the controller, the controller controls the cutter height adjustment drive device to automatically adjust the height of the cutter. Similarly, a cutter horizontal spacing adjustment drive device can also be provided to adjust the spacing between the two cutters to meet the cutting requirements of boxes 201 with different lengths. The cutter assembly 26 and the pressing plate assembly 27 can share the horizontal spacing adjustment drive device.

[0065] As Figure 8 and Figure 9As shown in the figure, the pressing plate assembly 27 of this embodiment includes two groups of pressing plates. Both the pressing plate assembly 27 and the cutting tool assembly 26 are connected to the motion mechanism 28 through connecting plates. The first connecting plate is respectively connected to the first cutting tool 261 and the first pressing plate 271, and the second connecting plate is respectively connected to the second cutting tool 262 and the second pressing plate 272. The connecting plate is L-shaped, including a horizontal plate 281 and a vertical plate 282. The cutting tool is connected to the lower surface of the horizontal plate 281, and the pressing plate is connected to the outer side surface of the vertical plate 282. The two horizontal plates 281 are arranged in parallel and are connected to the driving end of the motion mechanism 28 through a linear motion device 283 (horizontal spacing adjustment driving device). The motion mechanism 28 is used to drive the connecting plate and the cutting tool to move horizontally in a direction close to 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 pressing plate or the cutting tool so that it corresponds to the positions of the two sides of the box 201. That is, the motion direction of the linear motion device 283 and the motion direction of the motion mechanism 28 are both horizontal directions, but the motion directions are perpendicular to each other. For example, if the linear motion device 283 moves along the length direction of the box 201, the motion mechanism 28 moves along the width direction of the box 201. The cutting tool height adjustment driving device and the pressing plate height adjustment driving device 273 move along the height direction of the box 201. The pressing plate is fixed to the outer surface of the vertical plate 282 through the pressing plate height adjustment driving device 273. The pressing plate height adjustment driving device 273 is used to adjust the lifting height of the pressing plate to achieve different functions. For example, after the cutting tool finishes cutting the box 201, the two sides of the box 201 diverge outward, but do not completely open to form an opening. At this time, it is necessary for the pressing plate to rise above the upper surface of the box 201 and press downward against the positions of the two sides to form a through channel at both ends of the box 201. When the pressing plate is pressed downward until the upper surface of the pressing plate is basically flush with the upper plane of the unpacking platform 22 or slightly lower than the upper surface of the unpacking platform 22, the pressing plate stops pressing. Preferably, the upper surface of the pressing plate can be slightly lower than the unpacking platform 22 to avoid the push plate 232 colliding with the edge of the pressing plate when pushing the lens 202 outward, hindering the normal ejection of the lens 202. During the process of pressing the sides of the box 201 downward, a certain distance can be maintained between the two pressing plates and the unpacking platform 22 respectively so that the two sides of the box 201 can be smoothly pressed down.

[0066] When the cutting tool cuts the box 201, it can be carried out from the inside to the outside. That is, when two groups of unpacking mechanisms 2 are provided, the cutting tools on both sides cut from the middle to both sides respectively. In this way, when the cutting tool retracts after cutting, it can just drive the pressing plate back to the working position above the box 201, which is beneficial to improving work efficiency.

[0067] Such as Figure 10As shown, the push plate assembly 23 of this embodiment includes a push plate driving device 231 and a push plate 232. The push plate driving device 231 is used to drive the push plate 232 to move in a direction close to or away from the unpacking platform 22. The lower surface of the push plate 232 needs to be slightly higher than the upper surface of the unpacking platform 22. The push plate driving device 231 can be a linear motion mechanism such as a linear module, etc.

[0068] As Figure 1 and Figure 2 As shown, the device for removing the lens package in the embodiment of the present application further includes a material conveyor belt 11 provided on the workbench 10, a tray sensor 12 and a tray barcode scanner 18 provided at the entrance of the material conveyor belt 11, and a first material blocking assembly 13. The device for removing the lens package further includes a controller. In order to improve the efficiency of removing the lens 202, the material conveyor belt 11 can be provided in the middle of the workbench 10, and a unpacking mechanism 2 is provided on each side of the material conveyor belt 11. The two unpacking mechanisms 2 can work simultaneously, thereby improving the unpacking efficiency. At this time, two boxes 201 containing lenses 202 can be placed in the same tray 200 at the same time, so as to transport the two boxes 201 at the same time.

[0069] The material conveyor belt 11 is used to convey the tray 200, receive the tray 200 transferred from the previous process or directly receive the tray 200 containing the lens box 201, so as to transfer the tray 200 to the next process.

[0070] The tray sensor 12 is used to detect whether there is a tray 200 entering at the entrance of the material conveyor belt 11. The tray sensor 12 can be a presence / absence detection sensor, etc., and can be provided at the entrance of the material conveyor belt 11. After detecting that there is a tray 200 entering at the entrance of the material conveyor belt 11, the tray sensor 12 immediately sends the tray 200 detection result to the controller, and the controller controls the first material blocking assembly 13 to rise to block the tray 200 from continuing to move forward.

[0071] The tray barcode scanner 18 is provided on the workbench 10 near the first material blocking assembly 13, and is used to scan the identification code of the tray 200 and send the scanning result to the controller.

[0072] The controller is used to control the first material blocking assembly 13 to rise to block the tray 200 from moving forward after the tray sensor 12 detects that there is a tray 200 entering the material conveyor belt 11; after the tray barcode scanner 18 completes the scanning of the identification code of the tray 200, the controller controls the first material blocking assembly 13 to lower to release the tray 200.

[0073] The first material blocking assembly 13 can be a baffle controlled by a driving device such as a lifting cylinder, a hydraulic cylinder or an electric cylinder.

[0074] As Figure 2 , Figure 3 and Figure 10As shown in the figure, for the convenience of collecting the waste boxes 201 after demolition, a waste box conveying channel 21 can also be provided. The waste box conveying channel 21 is arranged under 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 arranged below the box demolition platform 22, and the waste box outlet 211 is arranged on the side wall of the frame 1 under the workbench 10. A waste box 201 conveying component is arranged between the waste box inlet 212 and the waste box outlet 211. The waste box 201 conveying component is used to output the waste box 201 that enters 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 component can be, for example, a conveying belt or other devices. When a box demolition mechanism 2 is provided on each side of the material conveying belt 11, a waste box inlet 212 can be respectively arranged below each box demolition platform 22, that is, the same waste box conveying channel 21 includes two waste box inlets 212 and one waste box outlet 211. No matter which waste box inlet 212 the waste box 201 enters the waste box conveying channel 21 from, it is conveyed out through the same waste box outlet 211. A waste box 201 processing device or a collection device can be connected at the waste box outlet 211 to facilitate the rapid processing of the waste box 201.

[0075] To increase the collection efficiency of the waste boxes 201 and reduce manual operation, a dumping component can be provided. The dumping component is used to make the waste boxes 201 on the box demolition platform 22 fall into the waste box inlet 212. For example, the dumping component can include a rotating device. The driving end of the rotating device is connected to the box demolition platform 22. The rotating device drives the box demolition platform 22 to rotate in the vertical direction, so that the boxes 201 on the box demolition platform 22 (at this time, the fixing component releases the boxes 201) fall into the lower waste box inlet 212. The rotating device can be, for example, a rotating cylinder. The specific structural type of the rotating device is not limited, as long as it can realize the flipping of the box demolition platform 22 so that the waste boxes 201 fall into the waste box inlet 212.

[0076] As Figures 1 to 3 As shown in the figure, the equipment for demolishing the lens packaging further includes a loading robot 14 and a second material blocking component. The second material blocking component is located at the material taking station. The material taking station is the downstream station of the station where the first material blocking component 13 is located, and is used to block or release the tray 200; the loading robot 14 is used to place the boxes 201 on the tray 200 at the material taking station on the box demolition platform 22.

[0077] For example, the material taking station can be the next station adjacent to the first material blocking component 13. After the tray barcode scanner 18 completes the scanning of the tray identification code, the controller controls the first material blocking component 13 to descend, so that the tray 200 continues to move forward to the material taking station driven by the material conveying belt 11. At this time, the second material blocking component rises to block the tray 200 from continuing to move forward.

[0078] The loading robot 14 can, for example, grasp the box 201 located in the tray 200 by means of a gripper, or can also grasp the box 201 by means of suction cup adsorption. A fixed or movable distance sensor module can also be arranged near the material taking station or near the first baffle component 13. The distance sensor module can include a moving component for driving the distance sensor to move, and a distance sensor for detecting the relative position relationship between the box 201 and the tray 200, and sending the distance detection result to the controller. The controller controls the loading robot 14 to move to a preset position according to the distance detection result to accurately grasp the box 201. When a box opening mechanism 2 is provided on each side of the material conveyor belt 11, the same loading robot 14 can be used to load the box opening platforms 22 on both sides in sequence.

[0079] Such as Figure 8 And Figure 11As shown, the box-unloading mechanism 2 further includes a box transfer platform 24. The loading robot 14 is also used to place the box 201 on the tray 200 at the material-taking station onto the box transfer platform 24. A flipping assembly 25 is provided on the box transfer platform 24, and the flipping assembly 25 is used to flip the box 201 on the transfer platform by 180°. Since the box 201 may be placed in the tray 200 in the wrong orientation, when the box 201 is placed in the wrong orientation, that is, the groove surface of the protective shell 203 of the lens 202 faces upward. At this time, 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, then the automatic removal of the protective shell 203 cannot be completed by the equipment. Therefore, the box-unloading mechanism 2 is provided to realize the automatic operation of flipping the box 201. By scanning the upper surface of the box body, it can be determined whether there is an identification code on the upper surface of the box 201 to distinguish whether the box 201 is placed in the wrong orientation. The box 201 placed in the wrong orientation needs to be first placed by the loading robot 14 at the box transfer platform 24 for flipping and then placed on the box-unloading platform 22. Specifically, the flipping assembly 25 may include, for example, two clamping plates 251, a flipping drive device 252, and a lifting drive device 253. The two clamping plates 251 are respectively connected to the drive ends of the clamping drive device and the flipping drive device 252. The fixed end (non-drive end) of the flipping drive device 252 is connected to the drive end of the lifting drive device 253. The clamping drive device may be, for example, two drive rods of a cylinder. The two drive rods are respectively fixedly connected to the corresponding clamping plates 251. The clamping drive device is used to drive the two clamping plates 251 to move away from or close to each other to loosen or clamp the box 201 on the box transfer platform 24. The flipping drive device 252 is used to drive the two clamping plates 251 to simultaneously perform an up-and-down flip of 180°. The flipping drive device 252 may be, for example, a rotary cylinder. The lifting drive device 253 is used to drive the two clamping plates 251 to perform up-and-down lifting, so that the clamping plates 251 avoid interference with the lower box transfer platform 24 when clamping the box 201 to flip the box 201. For example, when the box 201 needs to be flipped, the distance between the two clamping plates 251 can be adjusted first through the clamping drive device to clamp the box 201, then the lifting drive device 253 drives the clamping plates 251 and the box 201 to rise to a certain height, and finally the flipping drive device 252 drives the box 201 to flip 180°. The lifting drive device 253 drives 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 away the box 201 and places it on the box-unloading platform 22.

[0080] As Figure 1 、 Figure 2 and Figure 8As shown in the figure, the device for removing the lens packaging in this embodiment may further include a protective shell removing mechanism 3, which includes a protective shell removing platform 32, a protective shell removing robot 33, and a protective shell conveying channel 31.

[0081] The protective shell removing platform 32 is located at the station downstream of the box removing platform 22. The push plate assembly 23 is used to push the lens 202 out of the box 201 through the opening of the box 201 to the protective shell removing platform 32. Similarly, one protective shell removing platform 32 can be provided on each side of the material conveyor belt 11.

[0082] The protective shell conveying channel 31 is arranged under the workbench 10 and includes a protective shell inlet 312 and a protective shell outlet 311. The protective shell inlet 312 is arranged on the workbench 10, and the protective shell outlet 311 is arranged on the side wall of the frame 1 under the workbench 10; a protective shell 203 conveying component is arranged between the protective shell inlet 312 and the protective shell outlet 311, and the protective shell 203 conveying component is used to output the protective shell 203 entering the protective shell conveying channel 31 from the protective shell inlet 312 to the outside of the protective shell conveying channel 31 through the protective shell outlet 311. The structure of the protective shell conveying channel 31 is similar to that of the waste box conveying channel 21 and will not be elaborated here. The two protective shell removing platforms 32 correspond to the two protective shell inlets 312, and the two protective shell inlets 312 share the same protective shell outlet 311.

[0083] The protective shell removing robot 33 is used to take away the protective shell 203 covering the lens 202 and put the protective shell 203 into the protective shell inlet 312.

[0084] The protective shell removing platform 32 and the box removing platform 22 are on the same central axis. And for facilitating the removal of the protective shell 203, a centering and fixing component can also be arranged on the protective shell removing platform 32. This centering and fixing component is used to make the lens 202 and the protective shell 203 pushed by the push plate 232 located in the middle of the protective shell removing platform 32 to facilitate the removal of the protective shell 203. The centering and fixing component can, for example, include an adjusting centering mechanism and an adsorption fixing mechanism. The adjusting centering mechanism makes the protective shell 203 and the lens 202 centered by pushing, clamping, etc., and then adsorbs and fixes the lens 202 through the adsorption fixing mechanism. In this way, when removing the protective shell 203 of the lens 202, it can be ensured that the lens 202 will not move along with it. When it is necessary to take away the lens 202, the adsorption fixing mechanism can be made to relax the adsorption on the lens 202.

[0085] The protective shell removing robot 33 can also grab the protective shell 203 through, for example, a clamping jaw or an adsorption function. After the protective shell 203 is pushed out of the box 201, the identification code on the protective shell 203 can also be scanned by a scanning component arranged near the protective shell removing platform 32. The protective shell removing robot 33 can move back and forth between the protective shell removing platform 32 and the protective shell inlet 312.

[0086] As shown Figures 1 to 3 in the figure, the device for removing the lens packaging further includes a blanking robot 15, a third material blocking component, a first blanking conveying component 16 and a second blanking conveying component 17.

[0087] The third material blocking component is located at the blanking waiting station, which is the downstream station of the material picking waiting station, and is used to block or release the tray 200. After the tray 200 is released by the second material blocking component at the material picking waiting station, it arrives at the downstream blanking waiting station, and the third material blocking component blocks it.

[0088] The blanking robot 15 is used to move the lens 202 on the lens protective shell removing platform 32 into the tray 200 at the blanking waiting station. Two lens protective shell removing platforms 32 share one blanking robot 15.

[0089] The controller is further used to convey the tray 200 at the blanking waiting station out by the first blanking conveying component 16 or by the second blanking conveying component 17. The first blanking conveying component 16 is used to convey the correct tray 200, where the correct tray 200 means that the identification code of the tray 200 matches the identification code of the lens 202; the second blanking conveying component 17 is used to convey the incorrect tray 200, where the incorrect tray 200 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 with 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 component.

[0090] The embodiment of the present application further provides a method for removing the lens packaging, which is used for the device for removing the lens packaging in the above embodiment. The method for removing the lens packaging includes the following steps:

[0091] Place the box 201 containing the lens 202 on the box opening platform 22;

[0092] Fix the box 201 on the box opening platform 22 through the fixing component;

[0093] Move the cutter assembly 26 to cut the box 201 at the upper parts of the two sides of the box 201 respectively, and then withdraw in a direction away from the box 201;

[0094] Move the pressing plate assembly 27 to make the pressing plates of the pressing plate assembly 27 located above the two sides of the box 201 respectively, and move the pressing plates downward. The pressing plates press the two sides of the box 201 downward to form openings on both sides of the box 201. Stop moving the pressing plates until the upper surface of the pressing plates is basically flush with the upper surface of the box opening platform 22;

[0095] Move the push plate assembly 23 so that the push plate 232 of the push plate assembly 23 moves towards the opening of the box 201, extends into the box 201 from the opening on one side, and extends out of the box 201 from the opening on the other side, and push out the lens 202 from the box 201.

[0096] Specifically, the method for removing the lens packaging in this embodiment is described by taking a device for removing the lens packaging, which includes two sets of box-opening mechanisms 2 and a protective shell-removing mechanism 3 (one set of box-opening mechanism 2 and one set of protective shell-removing mechanism 3 are symmetrically arranged on both sides of the material conveyor belt 11) as an example. The method specifically includes the following steps:

[0097] S1. Provide a tray 200 containing materials and load the materials.

[0098] This material refers to the box 201 containing the lens 202. According to the actual needs of the device, the number of boxes 201 placed in the tray 200 can be two. At the same time, for the convenience of 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 is defined as the No. 1 tray 200, the identification code of the box 201 placed in the first position of the No. 1 tray 200 is defined as box 1, and the identification code of the box 201 placed in the second position is defined as box 2. There is a one-to-one correspondence between box 1 and the No. 1 tray 200, including the positional relationship of box 1 in the No. 1 tray 200; similarly for box 2 and the No. 1 tray 200. If the protective shell 203 of the lens 202 is also included in the box 201, the identification code of the protective shell 203 can also be scanned to match the identification code of the corresponding box 201, so as to ensure that when the lens 202 after unpacking is finally placed back on the tray 200, the lens 202 and the tray 200 are still in a matching relationship to prevent material confusion.

[0099] The tray 200 can be transferred from the production line of the previous process to the device for removing the lens packaging in this embodiment, or placed on the material conveyor belt 11 of the device in this embodiment in other manual or automatic ways.

[0100] S2. Identification detection.

[0101] The tray sensor 12 detects that there is a tray 200 entering the material conveyor belt 11, sends the detection result of the tray 200 to the controller, and the controller controls the first material blocking component 13 to rise to block the tray 200 from moving forward;

[0102] The tray barcode scanner 18 scans the identification code of the tray 200 and sends the scanning result to the controller;

[0103] The controller controls the first material blocking component 13 to descend, and the controller controls the second material blocking component to rise.

[0104] S3. The loading robot 14 picks up materials.

[0105] The pallet 200 continues to move forward and is intercepted by the second material blocking component at the material picking station; the distance sensor module respectively detects the positional relationship between the two boxes 201 and the pallet 200; the scanning device scans the upper surface of the box 201. If the identification code of the box 201 is scanned, it means the box 201 is placed correctly, otherwise it is placed reversely.

[0106] The controller controls the loading robot 14 to grab the corresponding box 201 according to the positional relationship between the box 201 and the pallet 200. When the box 201 is placed correctly, the loading robot 14 places the box 201 on the box opening platform 22; if the box 201 is placed reversely, the loading robot 14 places the box 201 on the box transfer platform 24 for flipping and then places it on another box opening platform 22.

[0107] The second material blocking component descends, the third material blocking component rises, and the pallet 200 continues to move forward and is intercepted by the third material blocking component at the material unloading station.

[0108] S4. Remove the box 201.

[0109] After the box 201 is placed on the box opening platform 22, the fixing component extends and fixes the box 201 on the box opening platform 22.

[0110] Two groups of cutting knives respectively perform horizontal cutting on the upper parts of the two side faces 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 side faces of the box 201 spread outwards, and the cutting knives retract.

[0111] Two pressing plates rise above the two side faces of the box 201 and move downwards to press the two side faces of the box 201 below the surface of the box opening platform 22, forming openings on both sides of the box 201. When the upper surface of the pressing plate is flush with or slightly lower than the upper surface of the box opening platform 22, the pressing plate stops moving.

[0112] The push plate 232 moves towards the direction close to the opening of the box 201 and enters the inside of the box 201, pushing the lens 202 and the protective shell 203 covering the lens 202 to the protective shell removal platform 32.

[0113] The dumping component drives the box opening platform 22 to rotate so that the waste box 201 enters the waste box inlet 212 and is discharged from the waste box outlet 211.

[0114] S5. Unload after removing the protective shell 203.

[0115] Scan the identification code on the protective shell 203 to determine whether it matches the identification code of the pallet 200.

[0116] The de-shelling robot 33 grabs the protective shell 203 and puts it into the protective shell inlet 312, and the protective shell 203 conveying component discharges it out of the device from the protective shell outlet 311.

[0117] The blanking robot 15 respectively grabs the lenses 202 after unpacking and places them on the trays 200 at the blanking stations.

[0118] The controller determines whether the identification codes of the trays 200 and the lenses 202 match. If they match, it controls the tray 200 to be output by the first blanking conveying component 16. If they do not match, it controls the tray 200 to be output by the second blanking conveying component 17.

[0119] The device and method for removing the lens packaging provided by the embodiments of the present application can effectively improve the efficiency of removing the lens packaging, greatly reduce the workload of manual operations, reduce the production cost, and improve the degree of automation of unpacking.
