[0032] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings.

[0033] Please see Figures 1-11As shown, an automatic packaging machine 10 includes: a small box feeding and opening device 1000, a small box conveying and packaging device 2000, a large box feeding and opening device 3000, a large box conveying and packaging device 4000, and a small box transfer device 5000; the small box feeding and opening device 1000 is disposed at one end of the small box conveying and packaging device 2000; the small box conveying and packaging device 2000 includes a small box conveying module 2100 and a small box pushing component 2200, the small box pushing component 2200 is disposed on the small box conveying module 2100, and the small box pushing component 2200 is used to push the product on the small box conveying module 2100 into the small box; the large box feeding and opening device 3000 is disposed on the large box conveying module 2100. At one end of the packaging device 4000, the large box conveying and packaging device 4000 includes a large box conveying module 4100, a large box pushing component 4200, and a large box sealing component 4300. The large box pushing component 4200 and the large box sealing component 4300 are respectively disposed on the large box conveying module 4100. The large box pushing component 4200 is used to push multiple stacked small boxes into the large box, and the large box sealing component 4300 is used for sealing the large box. The small box transfer device 5000 is connected between the small box pushing component 2200 and the large box pushing component 4200. The small box transfer device 5000 is used to transfer and stack small boxes containing products onto the large box pushing component 4200.

[0034] It should be noted that, taking the packaging of pliers 30 as an example, the packaging of pliers 30 includes both small and large boxes. The small boxes are packaged first, followed by the large boxes. During packaging, the small box loading and opening device 1000 first opens the small boxes and transports them to the small box conveying module 2100. At this point, each small box on the small box conveying module 2100 corresponds to one pair of pliers 30. The small box conveying module 2100 then transports the small boxes and pliers 30 to the small box pushing assembly 2200, where the pliers 30 are pushed into the small boxes, thus completing the small box packaging operation for the pliers 30. After the small box packaging is completed, the small box transfer device 5000 transfers and stacks the small boxes containing the pliers 30 to the large box pushing assembly 4200. While awaiting the large box packaging operation, the large box loading and opening device 3000 opens the large box and transports it to the large box conveying module 4100. The large box conveying module 4100 then transports the large box to the large box pushing component 4200, where stacked small boxes can be pushed into the large box. After the large box pushing operation, the large box needs to be sealed. Therefore, in this embodiment, the large box conveying module 4100 continues to transport the large box containing the product to the large box sealing component 4300, where the large box sealing component 4300 seals the large box. This achieves fully automated packaging of both large and small boxes using the pliers 30, improving packaging efficiency, ensuring packaging quality, and reducing safety hazards. In this embodiment, the loading of the pliers 30 can be done manually or by a robotic arm. The robotic arm can be an existing three-axis robotic arm, which will not be elaborated upon here.

[0035] Traditional methods of opening packaging boxes typically involve manual labor. However, manual opening is slow and cannot meet the demands of large-scale, high-efficiency production. Another approach uses opening equipment, such as a pusher mechanism, to open the box and insert it into the interior, thus prying it open. However, this method is prone to causing scratches and damage to the box, reducing its appearance. Therefore, please refer to [the relevant documentation / reference]. Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the small box feeding and opening device 1000 includes: a support base 1100, a small box storage rack 1200, a material picking and opening module 1300, and an auxiliary opening module 1400. The small box storage rack 1200 is disposed on the support base 1100 and has a discharge port. The discharge port faces the material picking and opening module 1300. The material picking and opening module 1300 includes a material picking adsorption component 1310 and a material picking transfer component 1320. The material picking adsorption component 1310 is disposed on the material picking transfer component 1320 and is used to adsorb one side of the small box. The auxiliary box opening module 1400 includes an auxiliary box opening adsorption component 1410 and a box opening drive component 1420, wherein the box opening drive component 1420 is connected to the auxiliary box opening adsorption component 1410; the material picking and transferring component 1320 is used to drive the material picking and adsorption component 1310 to transfer the small box on the small box storage rack 1200 to the auxiliary box opening adsorption component 1410, wherein the auxiliary box opening adsorption component 1410 is used to adsorb and fix the other side of the small box, and the box opening drive component 1420 is used to drive the auxiliary box opening adsorption component 1410 to move away from the material picking and adsorption component 1310 so that the inner cavity of the small box opens.

[0036] It should be noted that multiple unopened small boxes are stacked on the small box storage rack 1200. When an opening and unloading operation is required, the material-picking adsorption component 1310 first adsorbs and fixes one side of one small box at the discharge port of the small box storage rack 1200. Then, the material-picking transfer component 1320 moves the material-picking adsorption component 1310 to the auxiliary opening adsorption component 1410. At this time, the auxiliary opening adsorption component 1410 adsorbs and fixes the other side of the small box. That is, the material-picking adsorption component 1310 and the auxiliary opening adsorption component 1410 respectively adsorb and fix the two sides of the small box. Therefore, when the material-picking suction member 1310 and the auxiliary box-opening suction member 1410 separate, the opening of the small box is naturally opened, thus opening the inner cavity of the small box. Since there are no actions that could cause scratches or damage to the small box during the entire opening process, compared to the existing method of opening the packaging box by pushing open the opening and inserting into the box, damage to the small box can be avoided, improving the appearance quality of the small box. At the same time, compared to the existing method of opening boxes manually, opening efficiency can be improved, enabling large-scale production. In this embodiment, when the material-picking suction member 1310 and the auxiliary box-opening suction member 1410 are adsorbing and fixing the two sides of the small box, the suction cups on the material-picking suction member 1310 and the auxiliary box-opening suction member 1410 are staggered. After the small box is opened, the suction cups on the material-picking suction member 1310 and the auxiliary box-opening suction member 1410 are basically aligned, thus further ensuring that the small box stands upright and does not collapse after opening.

[0037] The small box storage rack 1200 is inclinedly mounted on the support base 1100, with the discharge port of the small box storage rack 1200 facing downwards, so that small boxes are stacked on the discharge port, and the material picking and opening module 1300 is located below the discharge port. This allows the material picking suction member 1310 to directly suction and fix the small boxes on the small box storage rack 1200, and pull the small boxes out from the discharge port. Simultaneously, the inclined mounting of the small box storage rack 1200 means that after one small box is removed, the remaining small boxes will move directly down to the discharge port under gravity. Thus, continuous feeding of small boxes can be achieved without the need for additional components. In this embodiment, a sensor is installed on the small box storage rack 1200. The sensor is used to identify the storage status of the small boxes on the small box storage rack 1200. When the storage of small boxes is low, the sensor will identify the low storage and transmit a signal to the control terminal or issue an alarm to remind the operator to continue feeding materials. This allows the operator to continue feeding materials to the small box storage rack 1200, ensuring the continuous operation of the whole machine, reducing standby time, and improving efficiency. For example, the sensor can be a fiber optic sensor.

[0038] Please see Figure 3 As shown, in one embodiment, the small box storage rack 1200 is provided with multiple baffles 1210, each baffle 1210 being disposed on the discharge port, and the baffles 1210 being used to limit the movement of the small boxes. For example, three baffles 1210 are provided, respectively disposed at the bottom and both sides of the discharge port. The position of each baffle 1210 is adjustable. For example, the baffles 1210 on both sides are provided with mounting posts, which pass through the small box storage rack 1200. The position of the baffles 1210 can be adjusted by moving the mounting posts. The bottom baffle 1210 can have strip-shaped mounting holes, and the bottom baffle 1210 can be fixed to the small box storage rack 1200 by screws or bolts. The position of the bottom baffle 1210 can also be adjusted by changing the strip-shaped mounting holes.

[0039] Please see Figure 3 and Figure 4As shown, in one embodiment, the small box storage rack 1200 includes a base plate 1220 and at least two limiting side stops 1230. The two limiting side stops 1230 are respectively and adjustablely disposed on both sides of the base plate 1220, and a limiting cavity for the small box is formed between the two limiting side stops 1230. Thus, since the position of the limiting side stops 1230 is adjustable, the relative position of the two limiting side stops 1230 can be adjusted to accommodate small boxes of different sizes, thereby improving the versatility of the small box storage rack 1200. In this embodiment, the limiting side stop 1230 includes a limiting side plate 1231 and an adjusting corner block 1232. The adjusting corner block 1232 has an adjusting hole, and the base plate 1220 also has a mounting hole. The mounting hole on the base plate 1220 aligns with the adjusting hole on the adjusting corner block 1232, and the adjusting corner block 1232 is connected to the limiting side plate 1231. Thus, by changing the relative position of the adjusting corner block 1232 on the base plate 1220, the position of the limiting side plate 1231 can be adjusted, making it suitable for small boxes of different sizes. For example, the adjusting corner block 1232 can be detachably connected to the base plate 1220 using screws or bolts. Simultaneously, the limiting side plate 1231 and the adjusting corner block 1232 are also detachably connected using bolts or screws.

[0040] Please see Figure 3 and Figure 4As shown, in one embodiment, the material handling and transfer component 1320 includes a material handling drive cylinder 1321, a material handling swing component 1322, a swing frame 1323, and an auxiliary rotating component 1324. The material handling drive cylinder 1321 is connected to the material handling swing component 1322, the material handling swing component 1322 is connected to the swing frame 1323, the auxiliary rotating component 1324 is connected to the swing frame 1323, and the material handling adsorption component 1310 is mounted on the auxiliary rotating component 1324. When the material picking drive cylinder 1321 is started, the material picking swing component 1322 realizes the swing of the swing frame 1323. While the swing frame 1323 swings, the auxiliary rotating component 1324 drives the material picking adsorption component 1310 to rotate. In this way, through the cooperation of various components, the material picking adsorption component 1310 can be moved, thereby adsorbing and fixing the small box of the small box storage rack 1200 and transporting it to connect with the auxiliary box opening adsorption component 1410 to realize the box opening operation. Specifically, the material-picking swing component 1322 includes a swing block 1322a, a swing bearing seat 1322b, a long swing shaft 1322c, and a short swing shaft 1322d. The material-picking drive cylinder 1321 is connected to the swing block 1322a, the long swing shaft 1322c is connected to the swing block 1322a, the swing bearing seat 1322b is sleeved on the long swing shaft 1322c, and the long swing shaft 1322c and the short swing shaft 1322d are respectively connected to the swing frame 1323. When the material-picking drive cylinder 1321 is started, it drives the swing block 1322a to swing. The swing block 1322a drives the long swing shaft 1322c to rotate, which, together with the short swing shaft 1322d, realizes the swing of the swing frame 1323. The auxiliary rotating component 1324 includes an auxiliary bearing seat 1324a, a bearing swivel 1324b, an auxiliary rod 1324c, and a connecting rod 1324d. The auxiliary bearing seat 1324a is mounted on the support base 1100. The bearing swivel 1324b is rotatably connected to the auxiliary bearing seat 1324a. One end of the auxiliary rod 1324c is mounted on the bearing swivel 1324b, and the other end is connected to the connecting rod 1324d. The connecting rod 1324d is rotatably mounted on the swing frame 1323. The material-collecting adsorption component 1310 is mounted on the connecting rod 1324d. When the swing frame 1323 swings, it drives the rotation of the bearing swivel 1324b and the connecting rod 1324d, thereby realizing the movement of the material-collecting adsorption component 1310. Thus, by adopting a linkage drive structure, smooth and continuous movement can be achieved, while making the overall structure more compact and ensuring the stability of material collection. In this embodiment, a limiting buffer 1325 is also provided near the pendulum block 1322a to limit and buffer the swing of the pendulum block 1322a; specifically, the limiting buffer 1325 includes a limiting block and a buffer.

[0041] Please see Figure 3As shown, in one embodiment, the material-picking suction member 1310 includes a material-picking suction cup fixing frame and a material-picking suction cup. The material-picking transfer member 1320 is connected to the material-picking suction cup fixing frame, and the material-picking suction cup is mounted on the material-picking suction cup fixing frame. The material-picking suction cup is used to adsorb and fix the small box, thus avoiding damage to the small box.

[0042] Please see Figure 3 As shown, in one embodiment, the auxiliary box-opening suction component 1410 includes a suction cup mounting bracket and an auxiliary box-opening suction cup. One end of the suction cup mounting bracket is connected to the box-opening driving component 1420, and the auxiliary box-opening suction cup is disposed on the other end of the suction cup mounting bracket. In this embodiment, the box-opening drive component 1420 includes a drive cylinder 1422, a box-opening lower swing block 1421, a rotating shaft 1423, and two bearing seats 1424. The two bearing seats 1424 are arranged opposite to each other, and the rotating shaft 1423 is rotatably mounted on the two bearing seats 1424. The material-picking suction cup mounting bracket is installed on the rotating shaft 1423, and one end of the rotating shaft 1423 is connected to one end of the box-opening lower swing block 1421. The other end of the box-opening lower swing block 1421 is connected to the drive end of the drive cylinder 1422. By extending and retracting the drive cylinder 1422, the box-opening lower swing block 1421 is driven to swing, thereby realizing the rotation of the rotating shaft 1423, and thus realizing the swing of the suction cup mounting bracket.

[0043] Please see Figure 3 As shown, in one embodiment, the small box feeding and opening device 1000 further includes a small box positioning seat 1500, which is disposed on one side of the auxiliary opening module 1400. After the auxiliary opening suction cup fixes the small box, the small box is then transported to the small box positioning seat 1500 by the opening drive component 1420 to await unloading. In this embodiment, the small box positioning seat 1500 includes two spaced-apart small box positioning blocks, which respectively support the two ends of the small box. At the same time, a clearance area is formed between the two small box positioning blocks for temporary clearance of the auxiliary opening suction component 1410.

[0044] The small box loading and unloading device 1000 also includes a small box unloading robot 1600, which is located on one side of the small box positioning seat 1500. The small box unloading robot 1600 is used to remove the small boxes from the small box positioning seat 1500 and transport them to the next workstation. For example, the small box unloading robot 1600 includes a horizontal linear motor module, a lifting cylinder, and a suction component. The lifting cylinder is connected to the horizontal linear motor module and the suction component. The horizontal linear motor module, in conjunction with the lifting cylinder, drives the suction component to move, thereby realizing the handling operation of the small boxes. After the small box unloading robot 1600 removes the small box from the small box positioning seat 1500, the opening drive component 1420 drives the auxiliary opening suction component 1410 to reset, thus making the entire structure more ingenious and coherent.

[0045] Please see Figure 5 , Figure 6 and Figure 7 As shown, in one embodiment, the small box conveying module 2100 includes a small box conveyor belt 2110, a small box positioning carrier 2120, and a product positioning carrier 2130. The small box positioning carrier 2120 and the product positioning carrier 2130 are respectively disposed on the small box conveyor belt 2110, and one end of the small box positioning carrier 2120 is connected to one end of the product positioning carrier 2130. Thus, the small box is positioned by the small box positioning carrier 2120, and the product is positioned by the product positioning carrier 2130. Simultaneously, the connection between one end of the small box positioning carrier 2120 and one end of the product positioning carrier 2130 facilitates the direct pushing of the product into the small box.

[0046] Because the pusher assembly 2200 exerts a pushing force on the clamps 30 when pushing them into the small box, the position of the small box may shift. Therefore, to prevent the clamps 30 from failing to properly insert into the box due to positional displacement, please refer to [link to relevant documentation]. Figure 5 As shown, in one embodiment, the small box conveying and packaging device 2000 further includes a small box pressing component 2300. The small box pressing component 2300 includes a pressing mounting block 2310 and a small box pressing strip 2320. The pressing mounting block 2310 is disposed on the small box conveyor belt 2110 and is located on one side of the small box positioning carrier 2120. The small box pressing strip 2320 is disposed on the pressing mounting block 2310 and abuts against the top of the small box on the small box positioning carrier 2120. That is, the small box pressing component 2300 presses and positions the small box on the small box positioning carrier 2120, avoiding pushing the small box during the insertion of the pliers 30, which would prevent the pliers 30 from successfully inserting the box, thereby improving the boxing efficiency of the pliers 30. In this embodiment, the small box conveyor belt 2110 is a belt conveyor.

[0047] Please see Figure 5 and Figure 6 As shown, in one embodiment, the pusher into the small box assembly 2200 includes a primary pusher 2210, a secondary extrusion pusher 2220, a tertiary pusher 2230, and a quaternary pusher 2240. The primary pusher 2210, the secondary extrusion pusher 2220, the tertiary pusher 2230, and the quaternary pusher 2240 are respectively arranged on the small box conveying module 2100, and the primary pusher 2210, the secondary extrusion pusher 2220, the tertiary pusher 2230, and the quaternary pusher 2240 are respectively used to push the product into the small box.

[0048] It should be noted that since the small box in this invention is an open box at both ends, the sealing operation of the small box can be reduced. However, in order to prevent the pliers 30 from being unable to be fixed after being inserted into the small box, the unfolded size of the pliers 30 in this invention is larger than the size of the inner cavity of the small box. In this way, when the pliers 30 is put into the small box, the handles at both ends of the pliers 30 will abut against the side walls of the inner cavity of the small box. Thus, the pliers 30 is not easy to fall out of the inner cavity of the small box. However, this will also cause the pliers 30 to be unable to be inserted smoothly in one go. Therefore, in this embodiment, the insertion of the pliers 30 involves multiple steps. Depending on the actual situation, more than two insertion operations can be set. However, in this embodiment, in order to ensure that the pliers 30 is inserted into the box accurately and without error, and to reduce the damage to the small box when the pliers 30 is inserted into the box, four pushing and inserting operations are set. For example, firstly, the head of the pliers 30 is partially pushed into the small box by the first pushing component 2210. Since the tail handle of the pliers 30 is open, the tail handle of the pliers 30 needs to be squeezed by the second squeezing pushing component 2220 to make the tail handle retract. The opening size of the tail handle is controlled to be smaller than the size of the entrance of the small box cavity. While squeezing, the tail handle of the pliers 30 is pushed into the small box cavity gradually. At this time, the tail handle is not completely inserted into the box. Then, the pliers 30 is gradually pushed into the small box cavity by the third pushing component 2230 and the fourth pushing component 2240. After completing the four pushing and inserting operations, the pliers 30 is completely inserted into the box. Thus, by performing multiple push-and-feed operations, problems such as misalignment and tilting of the pliers 30 during the box-feeding process can be avoided. This prevents the pliers 30 from failing to properly insert the box during a single push, thereby improving the accuracy and stability of the pliers 30's box-feeding and increasing the success rate. Furthermore, the multiple push-and-feed operations allow the equipment to be adapted to various sizes of pliers 30, facilitating adjustments to the push-and-feed operation based on actual needs and enhancing the equipment's versatility.

[0049] Please see Figure 5 and Figure 6As shown, in one embodiment, the primary pusher 2210 includes a primary positioning sensor, a primary drive, and a primary pusher block. The primary positioning sensor is located above the small box positioning carrier. The primary pusher block is connected to the primary drive and is located on the side closer to the product positioning carrier. The primary drive is used to drive the primary pusher block to push the product on the product positioning carrier into the small box. That is, when the small box positioning carrier moves the small box to the primary positioning sensor, it triggers the primary drive to start and drives the primary pusher block to push the product on the product positioning carrier into the small box, realizing the first push-in operation.

[0050] Further, after the first feeding operation is completed, the clamping and feeding operation of the handle at the tail of the clamp 30 is performed. Specifically, the secondary extrusion feeding component 2220 includes a drive component mounting frame 2221, a lifting drive component 2222, an extrusion drive component 2223, two extrusion clamping blocks 2224, a secondary feeding block 2225, and a secondary drive component 2226; the drive component mounting frame 2221 is set on the small box conveying module 2100, the lifting drive component 2222 is mounted on the drive component mounting frame 2221, and the extrusion drive component 2223, the two extrusion clamping blocks 2224, and the secondary feeding block 2226 are all included. 5. The secondary drive component 2226 is connected to the lifting drive component 2222; the extrusion drive component 2223 is connected to the two extrusion clamping blocks 2224. The extrusion drive component 2223 is used to drive the extrusion clamping blocks 2224 to move closer or further away from each other, and the two extrusion clamping blocks 2224 are located on both sides of the clamp 30; the secondary drive component 2226 is connected to the secondary pusher block 2225. The secondary drive component 2226 is used to drive the secondary pusher block 2225 to push the clamp 30 into the small box.

[0051] It should be noted that the lifting drive component 2222 is mounted on the drive component mounting bracket 2221. The lifting drive component 2222 drives the lifting movement of the extrusion drive component 2223, the extrusion clamping block 2224, the secondary pusher block 2225, and the secondary drive component 2226, so that each component can move to a suitable height. When performing the extrusion and push operation on the pliers 30, the extrusion drive component 2223 first drives the two extrusion clamping blocks 2224 to move closer to each other. At the same time, the distance between the two extrusion clamping blocks 2224 needs to ensure that the tail handle of the pliers 30 can be smoothly pushed into the small box. Then, the secondary drive component 2226 drives the secondary pusher block 2225 to gradually push the pliers 30 into the small box. At the same time as pushing in, the two extrusion clamping blocks 2224 squeeze the two sides of the tail handle of the pliers 30, so that the pliers 30 closes. In this way, the pliers 30 can be smoothly pushed into the inner cavity of the small box. After the extrusion and boxing operation is completed, a third and fourth pushing operation can be performed. That is, the third pushing component 2230 and the fourth pushing component 2240 continue to push the clamps 30 into the box, so that the clamps 30 can be completely inserted into the small box. In this embodiment, the structure of the second and third pushing components 2230 is the same as that of the first pushing component 2210. It should also be noted that the lifting drive component 2222, the extrusion drive component 2223, and the second drive component 2226 can all be cylinders.

[0052] After the small box insertion operation of the pliers 30 is completed, the small box transfer device 5000 transfers the small box containing the product and stacks it onto the large box pusher assembly 4200. For details, please refer to [link to details]. Figure 7 As shown, the small box transfer device 5000 includes a linear motor drive module 5100, a rotary cylinder 5200, a lifting cylinder 5300, and a transfer adsorption component 5400. The rotary cylinder 5200 is connected to the linear motor drive module 5100, the lifting cylinder 5300 is connected to the rotary cylinder 5200, and the transfer adsorption component 5400 is connected to the lifting cylinder 5300. Thus, after the transfer adsorption component 5400 adsorbs and fixes the small box equipped with clamps 30 on the small box positioning carrier, the small box can be transferred to the large box feeding assembly 4200 through the cooperation of the linear motor drive module 5100, the rotary cylinder 5200, and the lifting cylinder 5300. This enables seamless transfer between large and small box packaging, improves automation, greatly reduces manual intervention, and improves packaging efficiency and quality. In this embodiment, a sensor is also provided on the small box conveying module 2100. The sensor identifies the small box positioning carrier, thereby controlling the start of the small box transfer device 5000.

[0053] Please see Figure 8As shown, in one embodiment, the large box loading and opening device 3000 includes a large box handling robot 3100, an opening positioning fixture 3200, an opening flat pusher 3300, and an opening side pusher 3400. The large box handling robot 3100 is used to transport the large box onto the opening positioning fixture 3200, which is used to position the box. The opening flat pusher 3300 is located on the opening side of the large box, and the opening side pusher 3400 is located on one side of the large box. This allows for automatic opening of the large box, improving production efficiency. Specifically, the large box is first transported to the opening positioning fixture 3200 by the large box transport robot 3100. Correspondingly, a vacuum suction cup structure is provided at the bottom of the opening positioning fixture 3200 to adsorb and fix the bottom of the large box. At the same time, the large box transport robot 3100 can be a three-axis robot with a vacuum suction cup, so the large box transport robot 3100 can adsorb and fix the top of the large box. The large box transport robot 3100 and the opening positioning fixture 3200 work together to adsorb and fix the two sides of the large box. Then, the large box transport robot 3100 moves away from the box positioning fixture 3200, so that the opening of the large box is opened. At the same time, the opening side pusher 3400 pushes one side of the large box, and the opening flat pusher 3300 extends into the inner cavity of the large box, thereby realizing the opening operation of the large box. In this way, scratches and damage to the large box can be reduced and the appearance quality of the large box can be improved. Specifically, the opening-side pushing component includes a lifting cylinder, a pushing cylinder, and an opening-side pushing block. The lifting cylinder is used to adjust the height of the opening-side pushing block, and the pushing cylinder is used to drive the opening-side pushing block into the inner cavity of the large box to ensure that the large box stands upright and does not collapse. The opening-side pushing component 3400 includes a sliding cylinder and an opening-side pushing block. In this embodiment, the large box loading and opening device 3000 also includes a lifting storage rack 3500, which lifts and loads the large box. The lifting storage rack includes a lifting cylinder and a storage rack.

[0054] Please see Figure 9 , Figure 10 and Figure 11 As shown, in one embodiment, the large box conveying module 4100 includes a large box conveyor belt 4110 and a large box positioning carrier 4120, with the large box positioning carrier 4120 mounted on the large box conveyor belt 4110. The large box positioning carrier 4120 performs the positioning operation of the large box, while the large box conveyor belt 4110 simultaneously transports the large box positioning carrier 4120. In this embodiment, the large box conveyor belt 4110 is a belt conveyor.

[0055] In one embodiment, to prevent the large box from shaking and shifting during transport, and to prevent the large box from shifting position when pushing the small box into the large box, the large box conveying and packaging device 4000 also includes a large box holding component 4300. The large box holding component 4300 is disposed on the large box conveying module 4100 and is used to hold and position the top surface and both sides of the large box. This ensures the large box remains completely upright and does not collapse, while preventing the large box from shifting position and thus preventing the small box from being pushed into the large box smoothly. This improves the accuracy and stability of the small box entering the large box, thereby increasing packaging efficiency.

[0056] Furthermore, the large box holding assembly 4300 includes an adjusting frame 4310, a large box top surface pressing strip 4320, and side pressing members 4330. The adjusting frame 4310 is disposed on one side of the large box positioning carrier. The large box top surface pressing strip 4320 and the side pressing members 4330 are respectively installed on the adjusting frame 4310. The large box top surface pressing strip is used to press and position the top surface of the large box, and the side pressing members 4330 are used to press and position the two sides of the large box. The adjusting frame 4310 is used to adjust the height of the large box top surface pressing strip 4320, thereby ensuring that the large box top surface pressing strip 4320 is in the optimal position. The side pressing member 4330 includes two side pressing cylinders and two pressing arms. The side pressing cylinders drive the pressing arms to press and position the side walls of the large box, ensuring that the large box will not shift or collapse when the small box is inserted into the large box, ensuring that the small box can smoothly enter the large box and improving packaging efficiency.

[0057] To ensure that the stacked smaller boxes are accurately pushed into the cavity of the larger box, and to prevent the smaller boxes from shifting or pressing against the larger box during insertion, thus avoiding problems such as misalignment or damage to the larger box, please refer to [the relevant documentation / reference]. Figure 9 and Figure 10 As shown, in one embodiment, the pusher into the large box assembly 4200 includes a stacking limiting member 4210, a large box guide member 4220, and a large box pusher member 4230. The stacking limiting member 4210 is located between the large box guide member 4220 and the large box pusher member 4230, and the large box guide member 4220 is located on the side close to the large box positioning carrier 4120. The large box guide member 4220 is used to extend into the inner cavity of the large box. When the stacking limiting member 4210 has multiple small boxes stacked on it, the large box pusher member 4230 is used to push the multiple small boxes of the stacking limiting member 4210 into the inner cavity of the large box.

[0058] It should be noted that after the pliers 30 are inserted into the small box, the small box transfer device 5000 transfers and stacks the small box onto the stacking limiter 4210, which ensures that the small box will not fall off. Once the required number of small boxes are stacked on the stacking limiter 4210, the large box guide 4220 extends into the inner cavity of the large box on the large box positioning carrier 4120. Then, the large box pusher 4230 is activated, pushing the small box from the stacking limiter 4210 along the large box guide 4220 into the inner cavity of the large box. In this way, the stacking limiter 4210 prevents the small box from shifting position, ensuring the accuracy and stability of the large box insertion; the large box guide 4220 prevents the large box from being affected by the lid at the opening end during the insertion process, thus improving the efficiency and accuracy of the insertion. Specifically, the stacking limiting component 4210 includes a movable limiting frame 4211 and a movable blocking block 4212. The movable limiting frame 4211 is provided with a small box stacking cavity, and a feeding port is provided at the small box stacking cavity. The movable blocking block 4212 is provided on the movable limiting frame 4211, and the blocking end of the movable blocking block 4212 is located at the feeding port. When the small box is fed, the movable blocking block 4212 moves away from the feeding port. After the small box feeding is completed, the movable blocking block 4212 moves to the feeding port to block the small box on the small box stacking cavity. For example, the movable blocking block 4212 is moved by two cylinders working together; the movable limiting frame 4211 is moved by a rodless cylinder. The guide component 4220 for the large box includes a lower support plate 4221, a left guide plate 4222, and a right guide plate 4223. The left guide plate 4222 and the right guide plate 4223 are located on both sides of the lower support plate 4221. The lower support plate 4221, the left guide plate 4222, and the right guide plate 4223 extend into the inner cavity of the large box to guide the entry of the large box. The left guide plate 4222 and the right guide plate 4223 are connected by a cylinder to move closer to each other and further away from each other. The lower support plate 4221 can be moved by a cylinder or set on a moving limit frame 4211. The movement of the moving limit frame 4211 drives the lower support plate 4221 into the inner cavity of the large box. In this way, the use of driving components can be reduced, which improves the continuity of the actions of each structure and the compactness of the overall structure. The large box pusher 4230 includes a large box pusher plate and a drive cylinder. The drive cylinder is connected to the large box pusher plate and drives the large box pusher plate to push the small box into the inner cavity of the large box.

[0059] After the small boxes are inserted into the large box, a sealing operation is required. Specifically, this is achieved automatically by the large box sealing component 4300. To prevent the large box lid from affecting the accuracy and stability of the insertion process, the large box is initially placed with the lid facing upwards before sealing. However, this hinders subsequent rapid sealing. Therefore, to improve sealing efficiency, the large box needs to be flipped over. Please refer to [link / reference]. Figure 9 and Figure 11 As shown, in one embodiment, the large box sealing assembly 4300 includes a large box flipping frame 4310, a lid-folding pusher 4320, and a sealing member 4330. The large box flipping frame 4310, the lid-folding pusher 4320, and the sealing member 4330 are respectively arranged sequentially on the large box conveying module 4100. The flipping part of the large box flipping frame 4310 is located at the bottom of the large box positioning carrier 4120, and the large box positioning carrier 4120 is provided with a clearance position. When it is necessary to flip the large box, the large box flipping frame 4310 flips the large box on the large box positioning carrier 4120 through the clearance position, so that the lid of the large box is placed downwards to facilitate the subsequent sealing operation. Specifically, the large box flipping frame 4310 includes a rotation drive 4311, a lifting drive 4312, and a suction cup flipping plate 4313. The rotation drive 4311 is connected to the lifting drive 4312, and the suction cup flipping plate 4313 is connected to the lifting drive 4312. The suction cup flipping plate 4313 is used to suction and fix the bottom of the large box, and the rotation drive 4311 cooperates with the lifting drive 4312 to flip the suction cup flipping plate 4313, thereby realizing the flipping operation of the large box. Furthermore, the folding cover pusher 4320 includes a side cover guide plate 4321, a side cover actuating plate 4322, an actuating rotary cylinder 4323, a folding edge plate (located at the bottom of the large box's lid, not shown in the figure), a folding edge cylinder, a push cover plate 4324, and a push cover cylinder 4325. The side cover actuating plate 4322 is connected to the actuating rotary cylinder 4323, the folding edge plate is connected to the folding edge cylinder, and the push cover plate 4324 is connected to the push cover cylinder 4325. The folding edges of the two side covers of the large box are achieved through the side cover guide plate 4321 and the side cover actuating plate 4322. The folding edge of the top cover is achieved through the cooperation of the folding edge plate and the push cover plate 4324. That is, the top cover is pushed up by the folding edge plate, and the top cover is pushed by the push cover plate 4324, thereby realizing the folding edge operation. Please refer to [reference needed]. Figure 11 As shown, the sealing component 4330 includes a sealing strip 4331, a sealing suction cup 4332, a suction cup lifting cylinder 4333, a sealing pressure plate 4334, a pressure plate lifting cylinder 4335, a sealing push plate 4336, and a push plate cylinder. The sealing suction cup 4332 is connected to the suction cup lifting cylinder 4333. The sealing suction cup 4332 is used to adhere and fix the top of the large box, and the suction cup lifting cylinder 4333 drives the sealing suction cup 4332 to rise, so that the opening of the large box can open. Furthermore, to prevent the large box from being directly sucked up and causing displacement, the tail of the large box is held and positioned by a sealing strip 4331; the sealing plate 4334 is connected to the pressure plate lifting cylinder 4335, and the sealing plate 4334 holds the inner folded edge of the top cover; the sealing push plate 4336 is connected to the push plate cylinder, and the sealing push plate 4336, in conjunction with the sealing plate 4334, pushes the inner folded edge of the top cover into the inner cavity of the large box, thereby realizing the sealing operation of the large box. After the sealing operation is completed, the large box can be unloaded by a corresponding robotic arm.
