Description

Technical Field

[0001] This application relates to the field of medical device manufacturing technology, and in particular to a loading and unloading system. Background Technology

[0002] Pre-filled products typically refer to products that are pre-filled and sealed in industries such as medical devices, pharmaceuticals, and diagnostic reagents, such as pre-filled syringes, pre-filled lyophilized bottles, and automated filling diagnostic reagent kits.

[0003] In the automated production process of pre-filled products and other materials, material assembly and processing require initial transfer through a loading and unloading system. After processing, the material is loaded into empty pallets by the system, and only then can the pallets containing the processed materials be removed. Therefore, the loading and unloading system, as a crucial link in material flow, directly impacts equipment production efficiency and determines the ease of material handling. Pallets, in particular, can serve as loading components for batches of materials, facilitating large-scale material handling within the system.

[0004] However, the current loading and unloading system has two main problems. First, after removing unprocessed materials from the pallets upon startup, material processing takes time. During this process, the loading and unloading system continues to remove unprocessed materials from the pallets, resulting in a continuous accumulation of empty pallets. Furthermore, the removal of defective materials during system operation also leads to an accumulation of empty pallets, hindering pallet transfer and requiring manual cleaning and temporary shutdowns, which severely impacts production efficiency and wastes labor costs. Second, due to the lag in material processing, by the time the last batch of materials is processed, all empty pallets have already been transported, leaving no empty pallets for these processed materials. Utility Model Content

[0005] The purpose of this application is to provide a loading and unloading system that can operate continuously without the need for manual empty pallet cleaning, thereby reducing labor costs and improving production efficiency. Furthermore, empty pallets are stored after the last batch of materials has been processed.

[0006] The embodiments of this application can be implemented as follows: This application discloses an implementation of a loading and unloading system, including a first loading and unloading device, a pallet conveying mechanism, a pallet transfer mechanism, a pallet temporary storage mechanism, and a second loading and unloading device; The first loading and unloading device is used to remove unprocessed materials from the pallet and transfer the pallet to the pallet conveying mechanism; The pallet transfer mechanism is used to transfer empty pallets to the pallet conveying mechanism or the pallet temporary storage mechanism; The pallet storage mechanism is used to temporarily store empty pallets transferred by the pallet transfer mechanism, and the temporarily stored empty pallets can be transferred back to the pallet conveying mechanism by the pallet transfer mechanism. The second loading and unloading device is used to load processed materials into empty pallets on the pallet conveying mechanism, and to stack the pallets.

[0007] In the above implementation, the first loading and unloading equipment can transfer pallets to the pallet conveying mechanism for transport and remove unprocessed materials from the pallets for assembly, processing, etc. The second loading and unloading equipment can transfer processed materials to empty pallets on the pallet conveying mechanism and stack multiple pallets containing processed materials for easy removal. Specifically, the pallet transfer mechanism can transfer excess empty pallets from the pallet conveying mechanism due to system startup and empty pallets resulting from the removal of unqualified materials during system operation to the pallet temporary storage mechanism for temporary storage. When there are no empty pallets on the pallet conveying mechanism or only one or a few empty pallets remain, the pallet transfer mechanism can transfer the temporarily stored empty pallets from the pallet temporary storage mechanism to the pallet conveying mechanism, allowing the second loading and unloading equipment to continue placing processed materials onto pallets and stacking them. In this way, the loading and unloading system can operate continuously after startup without the need for manual cleaning of empty pallets, thus reducing labor costs and improving production efficiency. Furthermore, empty pallets are also stored after the last batch of materials is processed.

[0008] In an optional embodiment, the pallet temporary storage mechanism includes a temporary storage base, a temporary storage translation component disposed on the temporary storage base, and at least two sets of temporary storage blocks disposed on the temporary storage translation component. The temporary storage translation component is used to hold empty pallets and can carry empty pallets to translate on the temporary storage base. At least two sets of temporary storage blocks are arranged side by side along the translation direction of the temporary storage translation component; Each set of temporary storage blocks includes at least two temporary storage blocks spaced apart along a direction perpendicular to the translation direction of the temporary storage translation component; The space between two adjacent sets of temporary storage blocks is used for placing empty pallets.

[0009] In the above embodiment, empty trays can be placed between two adjacent sets of temporary storage blocks, limiting the range of movement of the empty trays relative to the temporary storage translation component in the translation direction, preventing the empty trays from sliding relative to the temporary storage translation component as the temporary storage translation component starts and stops, and allowing the empty trays to be moved to different positions on the temporary storage base by the temporary storage translation component, so as to place more empty trays.

[0010] In an optional embodiment, the pallet storage mechanism further includes two baffle assemblies disposed on the storage base, the two baffle assemblies being distributed on both sides of the storage translation assembly, and the space between the two baffle assemblies being used for pallet placement.

[0011] In the above embodiment, baffle assemblies are provided on both sides of the temporary storage translation assembly to block the empty pallet, so as to prevent the empty pallet from sliding laterally off the pallet temporary storage mechanism.

[0012] In an optional embodiment, the pallet storage mechanism further includes a lifting plate and a lifting drive assembly connected to the lifting plate; The lifting drive assembly is located on the temporary storage base and is used to drive the lifting plate to rise and fall relative to the temporary storage base, so that the lifting plate lifts or lowers the empty tray.

[0013] In the above embodiment, the lifting plate is driven by the lifting drive component to lift one or more stacked empty pallets, so that the pallet transfer mechanism can transfer the lifted empty pallets to the pallet conveying mechanism.

[0014] In an optional implementation, a gap is left in the middle of the temporary translation component, and the lifting plate is located within the gap.

[0015] The above-described embodiment, by placing the lifting plate in the middle of the temporary storage and translation component, makes the entire pallet temporary storage mechanism more compact and improves space utilization.

[0016] In an optional embodiment, the pallet storage mechanism further includes a pallet clamping assembly disposed on the storage base, the pallet clamping assembly being used to clamp a pallet after the lifting plate lifts an empty pallet.

[0017] In the above embodiment, the pallet clamping assembly can clamp and fix the highest empty pallet after it has been lifted by the lifting plate. This allows the lifting plate to descend, increasing the distance between the empty pallet and the adjacent empty pallet below it, or increasing the distance between the last empty pallet and the lifting plate, thereby facilitating the pallet transfer mechanism to pick up the empty pallet from the pallet temporary storage mechanism.

[0018] In an optional embodiment, the pallet transfer mechanism includes a transfer base, a transfer translation component disposed on the transfer base, and a transfer gripping component connected to the transfer translation component. The transfer base is positioned above the pallet conveying mechanism; The transfer gripping component is used to grip the pallet; The transfer translation component is used to drive the transfer gripping component to translate between the pallet conveying mechanism and the pallet temporary storage mechanism.

[0019] In an optional implementation, the transfer and translation component can drive the transfer gripping component to translate on the transfer base, thereby enabling the transfer of the empty pallet gripped by the transfer gripping component between the pallet storage mechanism and the pallet conveying mechanism.

[0020] In an optional embodiment, the first loading and unloading equipment includes a feeding and conveying mechanism, a first loading mechanism, and a first unloading mechanism; The first feeding mechanism is used to transfer the pallet on the feeding conveyor mechanism to the pallet conveyor mechanism; The first unloading mechanism is used to remove the material from the pallet on the pallet conveying mechanism.

[0021] In the above embodiment, multiple pallets containing unprocessed materials can be stacked together on a feeding conveyor and sent to a first feeding mechanism. The first feeding mechanism can then transfer the pallets one by one to a pallet conveyor, which transports the pallets one by one. The first unloading mechanism can then remove the materials from each pallet on the pallet conveyor for easy delivery to the outside for processing.

[0022] In an optional embodiment, the second loading and unloading equipment includes a second loading mechanism, a second unloading mechanism, and an unloading conveying mechanism; The second feeding mechanism is used to transfer processed materials to empty pallets on the pallet conveying mechanism; The second unloading mechanism is used to transfer pallets from the pallet conveying mechanism to the unloading conveying mechanism for stacking.

[0023] In the above embodiment, the second feeding mechanism puts the processed material back into the empty pallet; as the pallet conveying mechanism continues to convey, the second unloading mechanism transfers the pallets filled with processed material on the pallet conveying mechanism to the unloading conveying mechanism and stacks them one by one so as to remove multiple stacked pallets at once.

[0024] In an optional embodiment, the pallet conveying mechanism includes a first conveying mechanism and a second conveying mechanism; The first loading and unloading device is used to remove unprocessed materials from the pallet and transfer the pallet to the first conveying mechanism; The pallet transfer mechanism is used to transfer empty pallets on the first conveying mechanism to the pallet storage mechanism or the second conveying mechanism, or to transfer empty pallets on the pallet storage mechanism to the second conveying mechanism; The second loading and unloading equipment is used to pick up the processed materials and load them into empty pallets on the second conveying mechanism, and to stack the pallets.

[0025] In the above embodiment, by setting two pallet conveying mechanisms, two pallet conveying tracks can be realized. One conveying track is used to provide pallets containing unprocessed materials so that the first loading and unloading equipment can take away the unprocessed materials for processing. The other conveying track is used to receive and convey empty pallets so that the second loading and unloading equipment can load the processed materials into the empty pallets. The two conveying tracks do not interfere with each other, thereby improving production efficiency.

[0026] In an optional embodiment, the pallet conveying mechanism includes a conveying base, a conveying translation component disposed on the conveying base, and at least two sets of conveying stops disposed on the conveying translation component; The conveying translation component is used to hold the pallet and is capable of carrying the pallet and translating it relative to the conveying base; At least two sets of conveying blocks are arranged side by side along the translation direction of the conveying translation assembly; Each set of conveying blocks includes at least one conveying block spaced apart along a direction perpendicular to the translation direction of the conveying translation assembly; The space between two adjacent sets of conveyor blocks is used for placing pallets.

[0027] In the above embodiment, a pallet can be placed between two adjacent sets of conveying blocks, which limits the range of motion of the pallet relative to the conveying translation component in the translation direction, and prevents the pallet from sliding relative to the conveying translation component when it starts and stops. The conveying translation component can move the pallet on the conveying base to change its position, so as to place more pallets.

[0028] In an optional embodiment, the pallet conveying mechanism further includes positioning components distributed on both sides of the conveying translation component, the positioning components being used to push the pallet to center the pallet on the conveying translation component.

[0029] In the above implementation, the positioning component can push the pallet to center it on the conveying and translating component, and determine its lateral position and its own angle and posture. This is beneficial for the first unloading mechanism to accurately grab the material on the pallet, for the second loading mechanism to accurately put the processed material into the material receiving slot on the pallet, and for the pallet transfer mechanism to accurately grab the empty pallet.

[0030] In an optional implementation, each of the positioning components corresponds to a corner of the tray; The positioning component includes a positioning base, a positioning drive unit disposed on the positioning base, and a positioning block connected to the positioning drive unit. The positioning block is provided with a mating groove that matches the corner shape of the tray; The positioning drive is used to drive the positioning block closer to or further away from the tray, so that the mating groove engages with or disengages from the corner of the tray.

[0031] In the above embodiment, each corner of the pallet is pushed by a positioning component. This multi-point positioning makes the position and angle of the pallet on the conveying and translation component more accurate. At the same time, the positioning drive drives the positioning component to move closer to or away from the corner of the pallet, which can realize the engagement or disengagement of each mating groove with a corner of the pallet. In this way, the pallet can be positioned on the conveying and translation component by the engagement of the mating groove with the corner of the pallet and the movement of the positioning component, which facilitates the first unloading mechanism to grab the material and the second loading mechanism to put the material in.

[0032] In an optional embodiment, at least four positioning components are arranged at intervals along the translation direction of the conveying translation component on the same side of the conveying translation component. Each pair of positioning components on the same side of the conveying translation component forms a group; The two adjacent sets of positioning components in the translation direction of the conveying translation component are the first set and the second set, respectively. The first set and the second set are used to push the two trays respectively. The two positioning components in the first group are a first positioning component and a second positioning component, and the two positioning components in the second group are a third positioning component and a fourth positioning component. The first positioning component, the second positioning component, the third positioning component and the fourth positioning component are arranged sequentially at intervals along the translation direction of the conveying translation component.

[0033] The above-described embodiments, by alternately setting positioning components corresponding to different pallets, allow for the setting of a greater number of positioning components based on the same translational length. This ensures that the pallet has multiple positions on the conveying translation component where its position and angle can be adjusted, further ensuring the accuracy of the pallet's lateral position and angle on the conveying translation component.

[0043] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] refer to Figure 1 and Figure 2 This application discloses a loading and unloading system, which includes a first loading and unloading device, a pallet conveying mechanism 400, a pallet transfer mechanism 500, a pallet temporary storage mechanism 600, and a second loading and unloading device. The first loading and unloading equipment is used to remove unprocessed materials from the pallet and transfer the pallet to the pallet conveying mechanism 400; The pallet transfer mechanism 500 is used to transfer empty pallets to the pallet conveying mechanism 400 or the pallet temporary storage mechanism 600; The pallet storage mechanism 600 is used to temporarily store empty pallets transferred by the pallet transfer mechanism 500, and the temporarily stored empty pallets can be transferred back to the pallet conveying mechanism 400 by the pallet transfer mechanism 500. The second loading and unloading equipment is used to load processed materials into empty pallets on the pallet conveyor mechanism 400, and to stack the pallets.

[0045] In this way, the first loading and unloading equipment can transfer pallets to the pallet conveyor mechanism 400 for transport and remove unprocessed materials from the pallets for assembly, processing, etc. outside. The second loading and unloading equipment can transfer processed materials to empty pallets on the pallet conveyor mechanism 400 and stack multiple pallets containing processed materials for easy removal. Specifically, the pallet transfer mechanism 500 can transfer excess empty pallets from the pallet conveyor mechanism 400 due to system startup and empty pallets due to the removal of unqualified materials during system operation to the pallet temporary storage mechanism 600 for temporary storage. When there are no empty pallets on the pallet conveyor mechanism 400 or only one or a few empty pallets remain, the pallet transfer mechanism 500 can transfer the empty pallets temporarily stored in the pallet temporary storage mechanism 600 back to the pallet conveyor mechanism 400 so that the second loading and unloading equipment can continue to place processed materials on pallets and stack them. In this way, the loading and unloading system can operate continuously after startup without the need for manual cleaning of empty pallets, thus reducing labor costs and improving production efficiency. Furthermore, empty pallets are stored after the last batch of materials has been processed.

[0046] In detail, the first loading and unloading equipment includes a feeding conveyor 100, a first loading mechanism 200, and a first unloading mechanism 300; the first loading mechanism 200 is used to transfer the pallet on the feeding conveyor 100 to the pallet conveyor 400; the first unloading mechanism 300 is used to remove the material from the pallet on the pallet conveyor 400.

[0047] In this way, multiple pallets containing unprocessed materials can be stacked together on the feeding conveyor 100 and sent to the first feeding mechanism 200. The first feeding mechanism 200 can then transfer the pallets one by one to the pallet conveyor 400. The pallet conveyor 400 transports the pallets one by one, and the first unloading mechanism 300 can remove the materials from each pallet on the pallet conveyor 400 for easy delivery to the outside for processing.

[0048] Among them, reference Figure 3 and Figure 4 The feeding and conveying mechanism 100 includes a feeding base 110 and a feeding and conveying translation component 120, a feeding stop block 130 and a feeding baffle assembly 140 disposed on the feeding base 110.

[0049] The feeding conveyor translation assembly 120 is used to hold the pallet and is able to carry the pallet to translate relative to the feeding base 110.

[0050] Two feeding baffle assemblies 140 are distributed on both sides of the feeding conveying translation assembly 120, and the area between the two feeding baffles 142 is used for placing the pallet; At least two sets of feeding blocks 130 are arranged side by side along the translation direction of the feeding conveying translation assembly 120. Each set of feeding blocks 130 includes at least two feeding blocks 130 spaced apart along a direction perpendicular to the translation direction of the feeding conveying translation assembly 120. The space between two adjacent sets of feeding blocks 130 is used for placing a pallet containing unprocessed material.

[0051] In this way, pallets containing unprocessed materials can be placed between adjacent feeding groups, limiting the range of movement of the pallets relative to the feeding conveyor translation assembly 120 in the translational direction. This prevents the pallets from sliding relative to the feeding conveyor translation assembly 120 as it starts and stops. The feeding conveyor translation assembly 120 can move empty pallets on the temporary storage base 610 to accommodate more empty pallets. In addition, feeding baffle assemblies 140 are provided on both sides of the feeding conveyor translation assembly 120 to block the pallets and prevent them from sliding laterally off the feeding conveyor mechanism 100.

[0052] Optionally, the feeding conveying translation assembly 120 includes a feeding translation motor 121 and a feeding translation transmission component 122 that is connected to the feeding translation motor 121. The feeding translation motor 121 is mounted on the feeding base 110. The feeding translation transmission component 122 can be a transmission belt or a transmission chain. A corresponding feeding stop 130 is set on the feeding translation transmission component 122. In this way, as the feeding translation motor 121 works, the feeding transmission component can move the pallet containing the unprocessed material.

[0053] The feeding baffle assembly 140 includes a feeding bracket 141 and a feeding baffle 142 connected to the feeding bracket 141. The feeding bracket 141 is fixed on the feeding base 110, and the feeding baffle 142 is located on the side of the fixed bracket close to the feeding conveying translation assembly 120, so that the feeding baffle 142 can limit the pallet in the lateral direction.

[0054] The first feeding mechanism 200 includes a first feeding base, a first feeding translation component, and a first feeding gripping component. The height of the first feeding base is higher than that of the feeding conveying mechanism 100. The first feeding translation component is located on the first feeding base, and the first feeding gripping component is located on the first feeding translation component. The first feeding translation component is used to drive the first feeding gripping component to translate between the pallet conveying mechanism 400 and the feeding conveying mechanism 100. The first feeding gripping component is used to grip or release the pallet containing unprocessed materials.

[0055] In this way, driven by the first feeding translation component, the first feeding gripping component first moves to above the feeding conveyor 100 and then grips the pallet containing unprocessed material. Then, it lifts the pallet and moves it to the pallet conveyor 400. After reaching above the pallet conveyor 400, it places the pallet on the pallet conveyor 400, thereby transferring the pallet on the feeding conveyor 100 to the pallet conveyor 400.

[0056] The first feeding translation component includes a first feeding translation motor and a first feeding transmission component connected to the first feeding translation motor. The first feeding transmission component can be any mechanism, such as a transmission chain, transmission belt, or ball screw, that can provide power from the first feeding motor to the first feeding gripping component for translation.

[0057] The first feeding gripping assembly includes a first feeding base, a first feeding gripping lifting motor disposed on the first feeding base, and a first feeding gripping claw connected to the first feeding gripping lifting motor. The first feeding base is slidably disposed on the first feeding base and connected to a first feeding translation assembly, so that the first feeding gripping motor and the first feeding gripping claw can be synchronously translated relative to the first feeding base. The first feeding gripping claw is used to grip or release the pallet, and the first feeding gripping lifting motor can drive the first feeding gripping claw to rise and fall, from gripping to lowering the pallet.

[0058] The first unloading mechanism 300 includes a first unloading gripping base, a first unloading translation component, and a first unloading gripping component. The height of the first unloading gripping base is higher than that of the feeding conveying mechanism 100. The first unloading translation component is mounted on the first unloading gripping base and the first unloading gripping component is mounted on the first unloading translation component. The first unloading translation component is used to drive the first unloading gripping component to translate between the pallet conveying mechanism 400 and the external area. The first unloading gripping component is used to grip or release unprocessed materials.

[0059] In this way, driven by the first unloading translation component, the first unloading gripping component first moves to above the pallet conveying mechanism 400 and then grips the unprocessed material in the pallet. After that, it lifts the material, moves it to the outside and releases the material. Then it resets and continues to grip the unprocessed material in the pallet on the pallet conveying mechanism 400, thus realizing the automatic removal of unprocessed material.

[0060] The first unloading translation component includes a first unloading translation motor and a first unloading translation transmission component connected to the first unloading translation motor. The first unloading translation transmission component can be any mechanism, such as a transmission chain, transmission belt, or ball screw, that can provide power from the first unloading motor to the first unloading gripping component for translation.

[0061] The first unloading gripping assembly includes a first unloading base, a first unloading gripping lifting motor disposed on the first unloading base, and a first unloading gripping claw connected to the first unloading gripping lifting motor. The first unloading base is slidably disposed on the first unloading base and connected to a first unloading translation assembly, so that the first unloading gripping motor and the first unloading gripping claw can be synchronously translated relative to the first unloading base. The first unloading gripping claw is used to grip or release unprocessed material, and the first unloading gripping lifting motor can drive the first unloading gripping claw to rise and fall, from gripping to releasing unprocessed material.

[0062] The second loading and unloading equipment includes a second loading mechanism 700, a second unloading mechanism 800, and an unloading conveying mechanism 900; the second loading mechanism 700 is used to transfer processed materials to empty pallets on the pallet conveying mechanism 400; the second unloading mechanism 800 is used to transfer pallets on the pallet conveying mechanism 400 to the unloading conveying mechanism 900 for stacking.

[0063] Thus, the second feeding mechanism 700 returns the processed material to the empty pallet; as the pallet conveying mechanism 400 continues to convey, the second unloading mechanism 800 transfers the pallets filled with processed material on the pallet conveying mechanism 400 to the unloading conveying mechanism 900 and stacks them one by one so that multiple stacked pallets can be removed at once.

[0064] It should be noted that the structure and principle of the second feeding mechanism 700 are basically the same as those of the first unloading mechanism 300, the structure and principle of the second unloading mechanism 800 are basically the same as those of the first feeding mechanism 200, and the structure and principle of the unloading conveying mechanism 900 are basically the same as those of the feeding conveying mechanism 100, which will not be elaborated here.

[0065] Optional, see reference Figures 5 to 8 The pallet conveying mechanism 400 includes a first conveying mechanism 410 and a second conveying mechanism 420; The first loading and unloading device is used to remove unprocessed materials from the pallet and transfer the pallet to the first conveying mechanism 410; Specifically, the first feeding mechanism 200 transfers the pallet on the feeding conveying mechanism 100 to the first conveying mechanism 410, and the first unloading mechanism removes the unprocessed material from the pallet on the first conveying mechanism 410 and sends it to the outside for processing.

[0066] The pallet transfer mechanism 500 is used to transfer empty pallets on the first conveying mechanism 410 to the pallet storage mechanism 600 or the second conveying mechanism 420, or to transfer empty pallets on the pallet storage mechanism 600 to the second conveying mechanism 420. The second loading and unloading equipment is used to pick up the processed materials and load them into empty pallets on the second conveying mechanism 420, and to stack the pallets.

[0067] Specifically, the second feeding mechanism 700 loads the processed material into an empty pallet on the second conveying mechanism 420, and the second unloading mechanism 800 transfers the pallet loaded with the processed material to the unloading conveying mechanism 900 for stacking.

[0068] In this way, by setting up two pallet conveying mechanisms 400, two pallet conveying tracks can be realized. One conveying track is used to provide pallets containing unprocessed materials so that the first loading and unloading equipment can take away the unprocessed materials for processing. The other conveying track is used to receive and convey empty pallets so that the second loading and unloading equipment can load processed materials into empty pallets. The two conveying tracks do not interfere with each other, thereby improving production efficiency.

[0069] The structure and principle of the first conveying mechanism 410 and the second conveying mechanism 420 are basically the same. Taking any one of the conveying mechanisms as an example, the pallet conveying mechanism 400 of this embodiment includes a conveying base 430, a conveying translation component 440 disposed on the conveying base 430, and at least two sets of conveying blocks 450 disposed on the conveying translation component 440. The conveyor translation assembly 440 is used to hold the pallet and is capable of carrying the pallet to translate relative to the conveyor base 430; At least two sets of conveying stops 450 are arranged side by side along the translation direction of the conveying translation assembly 440; Each set of conveying blocks 450 includes at least one conveying block 450 spaced apart along a direction perpendicular to the translation direction of the conveying translation assembly 440; The space between two adjacent sets of conveyor blocks 450 is used for placing pallets.

[0070] Thus, pallets can be placed between two adjacent sets of conveying blocks 450, limiting the range of motion of the pallets relative to the conveying translation component 440 in the translation direction, preventing the pallets from sliding relative to the conveying translation component 440 as the conveying translation component 440 starts and stops, and allowing the pallets to be moved on the conveying base 430 by the conveying translation component 440 to accommodate more pallets.

[0071] The conveying and translation component 440 includes a conveying and translation motor 441 and a conveying and translation transmission component 442 connected to the conveying and translation motor 441. The conveying and translation motor 441 is mounted on the conveying base 430. The conveying and translation component 440 can be a transmission belt or a transmission chain. The corresponding conveying stop 450 is set on the conveying and translation transmission component 442. In this way, as the conveying and translation motor 441 works, the conveying and translation transmission component 442 can carry the pallet and move it horizontally.

[0072] In this embodiment, reference Figure 9 The pallet conveying mechanism 400 also includes positioning components 460 distributed on both sides of the conveying translation component 440. The positioning components 460 are used to push the pallet so that the pallet is centered on the conveying translation component 440.

[0073] In this way, the positioning component 460 can push the pallet to center it on the conveying translation component 440, and determine its lateral position and its own angle and posture. This is beneficial for the first unloading mechanism 300 to accurately grab the material on the pallet, and also for the second loading mechanism 700 to accurately put the processed material into the material receiving slot on the pallet. It is also beneficial for the pallet transfer mechanism 500 to accurately grab the empty pallet.

[0074] Each positioning component 460 corresponds to a corner of the pallet; the positioning component 460 includes a positioning base 461, a positioning drive 462 disposed on the positioning base 461, and a positioning block 463 connected to the positioning drive 462; the positioning block 463 is provided with a mating groove 464 adapted to the shape of the corner of the pallet; the positioning drive 462 is used to drive the positioning block 463 to move closer to or away from the pallet, so that the mating groove 464 engages or disengages from the corner of the pallet.

[0075] Thus, each corner of the pallet is pushed by a positioning component 460. This multi-point positioning allows for more precise position and angle of the pallet on the conveying and translational component 440. At the same time, the positioning drive component 462 drives the positioning component to move closer to or away from the corner of the pallet, enabling each mating groove 464 to engage or disengage with a pallet corner. In this way, the engagement of the mating groove 464 with the pallet corner and the movement of the positioning component can position the pallet on the conveying and translational component 440, facilitating the first unloading mechanism 300 to grab materials and the second loading mechanism 700 to put materials in.

[0076] Optional, continue to refer to Figures 5 to 8 On the same side of the conveying translation component 440, there are at least four positioning components 460 arranged at intervals along the translation direction of the conveying translation component 440. Two positioning components 460 are grouped together on the same side of the conveying translation component 440; In the translation direction of the conveying translation component 440, two adjacent sets of positioning components 460 are respectively the first set and the second set, which are used to push the two trays respectively. The two positioning components 460 in the first group are the first positioning component 465 and the second positioning component 466, respectively. The two positioning components 460 in the second group are the third positioning component 467 and the fourth positioning component 468, respectively. The first positioning component 465, the second positioning component 466, the third positioning component 467 and the fourth positioning component 468 are arranged sequentially at intervals along the translation direction of the conveying translation component 440.

[0077] In this way, by alternately setting the positioning components 460 corresponding to different pallets, more positioning components 460 can be set on the same translation direction length, thereby ensuring that the pallet has multiple positions on the conveying translation component 440 where the position and angle can be adjusted, further ensuring the accuracy of the pallet's lateral position and angle on the conveying translation component 440.

[0078] refer to Figures 10 to 13 The pallet transfer mechanism 500 includes a transfer base 510, a transfer translation component 520 disposed on the transfer base 510, and a transfer gripping component 530 connected to the transfer translation component 520. The transfer base 510 is positioned above the pallet conveying mechanism 400; The transfer gripping component 530 is used to grip pallets; The transfer translation component 520 is used to drive the transfer gripping component 530 to translate between the pallet conveying mechanism 400 and the pallet temporary storage mechanism 600.

[0079] In this way, the transfer translation component 520 can drive the transfer gripping component 530 to move horizontally on the transfer base 510, thereby realizing the transfer of the empty pallet gripped by the transfer gripping component 530 between the pallet storage mechanism 600 and the pallet conveying mechanism 400.

[0080] The transfer and translation component 520 includes a transfer and translation motor 521 and a transfer and translation transmission component 522 connected to the transfer and translation motor 521. The transfer and translation transmission component 522 can be a transmission belt, transmission chain, ball screw or other component that can transmit the power of the transfer and translation motor 521 to the transfer and gripping component 530, as long as it can enable the transfer and gripping component 530 to translate relative to the transfer base 510.

[0081] The transfer gripping assembly 530 includes a transfer gripping base 531, a transfer rotary motor 532, a transfer rotary transmission component 533, a transfer lifting motor 534, and a transfer gripper 535, all mounted on the transfer gripping base 531. The transfer gripping base 531 is slidably mounted on a transfer base 510 and connected to a transfer translation assembly 520, allowing the transfer rotary motor 532, transfer rotary transmission component 533, transfer lifting motor 534, and transfer gripper 535 to move synchronously relative to the transfer base 510. The transfer gripper 535 is used to grip or release materials. The transfer rotary motor 532 is connected to the transfer gripper 535 via the transfer rotary transmission component 533, allowing the rotary motor to drive the transfer gripper 535 to rotate, adjusting its angle and facilitating alignment with the materials. The transfer lifting motor 534 is also connected to the transfer gripper 535 and drives it to rise and fall, enabling the transfer gripper 535 to grip or release materials.

[0082] The rotary transmission component 533 can drive the rotary gripper 535 to rotate using a transmission belt or chain. The connecting shaft between the rotary gripper 535 and the rotary transmission component 533 can be a sliding nested telescopic tube structure. In this way, the top end of the connecting shaft is fixedly connected to the rotary transmission component 533, and the rotary lifting motor 534 is fixedly connected to the bottom end of the connecting shaft. When the rotary lifting motor 534 is working, it can extend and retract the connecting shaft, thereby realizing the lifting and lowering of the rotary gripper 535.

[0083] refer to Figure 10 , Figure 14 and Figure 15 In this embodiment, the pallet temporary storage mechanism 600 includes a temporary storage base 610, a temporary storage translation component 620 disposed on the temporary storage base 610, and at least two sets of temporary storage blocks 630 disposed on the temporary storage translation component 620. The temporary storage and translation component 620 is used to hold empty pallets and is able to carry empty pallets and translate them on the temporary storage base 610. At least two sets of temporary storage blocks 630 are arranged side by side along the translation direction of the temporary storage translation component 620; Each set of temporary storage blocks 630 includes at least two temporary storage blocks 630 that are spaced apart along a direction perpendicular to the translation direction of the temporary storage translation component 620. The space between two adjacent sets of temporary storage blocks 630 is used for placing empty pallets.

[0084] In this way, empty pallets can be placed between two adjacent sets of temporary storage blocks 630, limiting the range of movement of the empty pallets relative to the temporary storage translation component 620 in the translation direction, preventing the empty pallets from sliding relative to the temporary storage translation component 620 as it starts and stops. The temporary storage translation component 620 can move the empty pallets on the temporary storage base 610 to change their position, so as to place more empty pallets.

[0085] The temporary storage translation component 620 includes a temporary storage translation motor 621 and a temporary storage translation transmission component 622 connected to the temporary storage translation motor 621. The temporary storage translation transmission component 622 can be a transmission chain or a transmission belt. A corresponding temporary storage stop 630 is set on the temporary storage translation transmission component 622. In this way, as the temporary storage translation motor 621 works, the temporary storage translation transmission component 622 can move the empty tray.

[0086] Optionally, the pallet storage mechanism 600 also includes two baffle assemblies disposed on the storage base 610. The two baffle assemblies are distributed on both sides of the storage translation assembly 620, and the space between the two baffle assemblies is used for placing the pallet.

[0087] Thus, by setting baffle assemblies on both sides of the temporary storage translation assembly 620 to block the empty pallet, the empty pallet is prevented from sliding laterally off the pallet temporary storage mechanism 600.

[0088] The temporary storage baffle assembly 640 includes a temporary storage bracket 641 and a temporary storage baffle 642 connected to the temporary storage bracket 641. The temporary storage bracket 641 is fixed to the temporary storage base 610, and the temporary storage baffle 642 is located on the side of the temporary storage bracket 641 close to the temporary storage translation assembly 620, so that the temporary storage baffle 642 can limit the empty pallet in the lateral direction.

[0089] The pallet temporary storage mechanism 600 also includes a lifting plate 650 and a lifting drive assembly 660 connected to the lifting plate 650. The lifting drive assembly 660 is located on the temporary storage base 610 and is used to drive the lifting plate 650 to rise or fall relative to the temporary storage base 610, so that the lifting plate 650 lifts or lowers empty pallets. In this way, the lifting plate 650 is driven by the lifting drive assembly 660 to lift one or more stacked empty pallets, making it convenient for the pallet transfer mechanism 500 to transfer the raised empty pallets to the pallet conveying mechanism 400.

[0090] The temporary storage and translation component 620 has a gap in the middle, and the lifting plate 650 is located in the gap. By placing the lifting plate 650 in the gap in the middle of the temporary storage and translation component 620, the structure of the entire pallet temporary storage mechanism 600 is more compact, improving space utilization.

[0091] The lifting drive assembly 660 is located on the lower side of the temporary storage base 610. A window 611 is provided in the temporary storage base 610 so that the lifting drive assembly 660 can pass through and connect with the lifting plate 650, which makes the structure more compact.

[0092] refer to Figure 16 The lifting drive assembly 660 includes a lifting electric cylinder 661 and a guide rod 662 connected to the lifting electric cylinder 661. The guide rod 662 passes through the window 611 and is connected to the lifting plate 650. In this way, the lifting electric cylinder 661 can drive the guide rod 662 to rise and fall, and the guide rod 662 carries the lifting plate 650 to rise and fall accordingly.

[0093] Continue to refer to Figure 14 and Figure 15 The pallet storage mechanism 600 also includes a pallet clamping assembly 670 disposed on the storage base 610, which is used to clamp a pallet after the lifting plate 650 lifts an empty pallet.

[0094] Thus, the pallet clamping assembly 670 can clamp and fix the highest empty pallet after it has been lifted by the lifting plate 650. This allows the lifting plate 650 to descend, increasing the distance between the empty pallet and the adjacent empty pallet below, or increasing the distance between the last empty pallet and the lifting plate 650, thereby facilitating the pallet transfer mechanism 500 to pick up the empty pallet from the pallet temporary storage mechanism 600.

[0095] Optional, see reference Figure 17 The pallet clamping assembly 670 includes a clamping bracket 671, a clamping cylinder 672 disposed on the clamping bracket 671, and a clamping plate 673 connected to the clamping cylinder 672. The clamping bracket 671 is vertically fixed on the temporary storage base 610. The clamping cylinder 672 is located at the top of the clamping bracket 671, and the clamping plate 673 is located on the side of the clamping cylinder 672 near the temporary storage translation assembly 620. In this way, when the clamping cylinders 672 on both sides drive the two clamping plates 673 to move closer or further away from each other, the pallet can be clamped or released.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
