[0003] In the related art, the battery modules on the production line are usually hoisted off the line by manually operating the lifting equipment. However, the above-mentioned off-line method requires manual placement of pallets, then hoisting the battery modules onto the corresponding pallets, and then transferring the pallets with the battery modules, which results in low off-line operation efficiency. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a offline device and a battery production line, aiming to solve the problem of low efficiency of the related art using lifting equipment to lift offline devices.

[0005] To achieve the above purpose, the technical solution adopted in the embodiment of the present application is:

[0006] In the first aspect, an embodiment of the present application provides an offline equipment, including a pallet loading device and a material conveying device; the pallet loading device includes a pallet grabbing mechanism and a pallet transmission mechanism, and the pallet grabbing mechanism is arranged on the surrounding side of the pallet transmission mechanism; the material conveying device includes a material grabbing mechanism and a material transmission mechanism, and the material grabbing mechanism is used to grab the material transmitted on the material transmission mechanism to the pallet transmitted on the pallet transmission mechanism.

[0007] The beneficial effects of the embodiments of the present application: the offline equipment provided by the embodiments of the present application utilizes a pallet loading device to place pallets, grabs pallets through a pallet grabbing mechanism and places them on a pallet transmission mechanism for transmission and movement, and at the same time utilizes a material conveying device to place materials, grabs materials transmitted on the material transmission mechanism through a material grabbing mechanism and places them on a pallet for transmission on the pallet transmission mechanism; thereby, the material grabbing mechanism can continuously grab materials and place them on a pallet transmitted on the pallet transmission mechanism, while the pallet with materials placed on it continues to be transmitted through the pallet transmission mechanism, and empty pallets are continuously grabbed and placed by the pallet grabbing mechanism, which effectively improves the efficiency of placing materials on pallets, and thus can effectively improve the offline efficiency of materials.

[0008] In some embodiments, the pallet transmission mechanism has a first loading station and a second loading station arranged in sequence along the conveying direction, the pallet grabbing mechanism is used to grab the pallet and send it to the first loading station, and the material grabbing mechanism is used to grab the material and send it to the second loading station.

[0009] By adopting the above-mentioned technical solution, the pallet grabbing mechanism can grab the empty pallet and place it into the first loading station of the pallet conveying mechanism, and the pallet conveying mechanism will transport it forward to the second loading station, so that the material grabbing mechanism can grab the material and place it onto the pallet at the second loading station; thus, the action of placing the pallet into the pallet conveying mechanism and the action of placing the material into the pallet are implemented at different places, that is, the action of placing the pallet into the pallet conveying mechanism and the action of placing the material into the pallet can be performed simultaneously, which effectively improves the rhythm of placing the material into the pallet, thereby further improving the material offline efficiency.

[0010] In some embodiments, the pallet conveying mechanism includes an endless conveyor belt having an offline station; the offline equipment also includes a removal mechanism, which is arranged at the offline station, and the removal mechanism is configured to be able to move the pallet and materials out of the endless conveyor belt.

[0011] By adopting the above-mentioned technical solution, the circular conveyor belt can drive the pallets for circular transportation, so that the pallets and materials can be stacked in a circular manner in sequence to achieve the purpose of stacking, and when the pallets and materials are stacked to a preset number of layers, they can be moved to the offline workstation, and the removal mechanism can move the stacked pallets and materials out of the circular conveyor belt to achieve offline.

[0012] In some embodiments, along the conveying direction of the endless conveyor belt, the first loading station, the off-line station and the second loading station are arranged in sequence.

[0013] By adopting the above-mentioned technical scheme, in the conveying direction along the circular conveyor belt, the pallets and materials can be stacked in sequence at the first loading station and the second loading station respectively. After the pallets are stacked at the first loading station, they are moved to the offline station to be offline. Thus, the stacked pallets and materials are formed with the top layer being a pallet, so that the materials can be effectively covered and protected.

[0014] In some embodiments, the offline equipment further includes a counting sensor for detecting the number of stacked trays, and the counting sensor is electrically connected to the removal mechanism.

[0016] In some embodiments, the removal mechanism includes a removal drive and a transfer roller group arranged on the circular conveyor belt. The transfer roller group is arranged at the offline workstation. The output end of the removal drive is connected to the transfer roller group and is used to drive the pallet to move along the conveying direction of the circular conveyor belt or move out of the circular conveyor belt.

[0017] By adopting the above-mentioned technical solution, the removal drive member can drive the transfer roller group to rotate, so that the transfer roller group arranged at the offline workstation can rotate to drive the pallet to move along the conveying direction of the circular conveyor belt and continue to stack, or the transfer roller group rotates to drive the stacked pallets and materials to move out of the circular conveyor belt and offline.

[0018] In some embodiments, the offline equipment further includes an offline transmission mechanism, which is connected to the endless conveyor belt, and the removal mechanism is configured to move the pallet and the material onto the offline transmission mechanism.

[0019] By adopting the above technical solution, the removal mechanism can move the stacked pallets and materials to the offline transmission mechanism, and the offline transmission mechanism will transport them to a preset position, effectively improving the convenience of material offline and transportation.

[0020] In some embodiments, the annular conveyor belt includes a first transmission segment and a second transmission segment, the first transmission segment and the second transmission segment intersect and form a downline station, and the downline transmission mechanism is connected to the first transmission segment and arranged in the extension direction of the first transmission segment.

[0021] By adopting the above-mentioned technical solution, pallets are circulated on the circular conveyor belt to stack materials and new pallets. When the stacked pallets and materials are transported from the second transmission section of the circular conveyor belt to the intersection with the first transmission section, the stacked pallets and materials are moved to the offline workstation. If the stacking operation is not completed, the pallets and materials can continue to be transported by the first transmission section. If the stacking operation is completed, the removal mechanism can move the stacked pallets and materials along the extension direction of the first transmission section and opposite to the conveying direction of the first transmission to the offline transmission mechanism, so that the stacked pallets and materials are moved to the specified position through the offline transmission mechanism.

[0022] In some embodiments, the endless conveyor belt further has a protection station, and along the conveying direction of the endless conveyor belt, the second loading station, the protection station and the first loading station are arranged in sequence.

[0023] By adopting the above-mentioned technical solution, in the second loading station, the material can be placed on the pallet, and in the process of transferring the pallet and the material to the first loading station, the material will first pass through the protection station, so that the material on the top can be covered and protected at the protection station to reduce the probability of bumping and wearing the material when stacking the pallets at the first loading station.

[0024] In some embodiments, the material conveying device further includes a weighing platform and a moving mechanism. The weighing platform is disposed on the peripheral side of the material conveying mechanism, and the moving mechanism is used to move the material from the material conveying mechanism to the weighing platform.

[0025] By adopting the above technical solution, the material transported by the material transmission mechanism can be moved to the weighing platform through the moving mechanism, and after the material is weighed on the weighing platform, it is grabbed by the material grabbing mechanism and placed on the pallet.

[0026] In some embodiments, the pallet loading device further includes a lifting mechanism, which is disposed in the second loading station and is used to lift the pallet in the second loading station.

[0028] In some embodiments, the offline equipment further includes a hoisting mechanism, and the hoisting mechanism is arranged on the peripheral side of the material conveying mechanism.

[0029] By adopting the above-mentioned technical solution and arranging a lifting mechanism around the material transmission mechanism, when a pallet loading device or a material grabbing mechanism fails, the material can be lifted off the line by the lifting mechanism, thereby reducing the probability of being unable to be taken off the line due to a failure.

[0030] In a second aspect, an embodiment of the present application further provides a battery production line, including the offline equipment as described above.

[0050] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0051] After the battery module is produced, it needs to be taken offline to move the battery module from the production line to the pallet for subsequent transfer operations. In the related art, the battery module on the production line is generally lifted off the line by manually operating the lifting equipment, and the pallet needs to be placed at the same time. After the lifting is completed, the pallet and the battery module need to be transferred by forklift transportation. Therefore, the above-mentioned offline method requires manual placement of the pallet, lifting the battery module to the corresponding pallet, and then transferring the pallet with the battery module, and the offline operation efficiency is low.

[0052] Based on the above considerations, in order to solve the problem of low efficiency of the related technology of using lifting equipment to lift the offline equipment, an offline equipment is designed, in which pallets are arranged through a pallet loading device to enable the pallets to be transported and moved on the pallet transmission mechanism, and the material conveyed on the material transmission mechanism is grabbed by the material grabbing mechanism and sent to the pallet transmitted on the pallet transmission mechanism; the material grabbing mechanism can continuously grab the material and put it into the pallet transmitted on the pallet transmission mechanism, and the pallet with material is continued to be transmitted through the pallet transmission mechanism, and the empty pallets are continuously grabbed and placed by the pallet grabbing mechanism, which effectively improves the efficiency of placing materials into the pallet.

[0053] The offline equipment disclosed in the embodiments of the present application can be used to perform offline operations on a variety of materials, including but not limited to battery modules, electrical components, metal structures, etc.; for example, taking the case where the materials include battery modules, the battery modules can be offline operated through the offline equipment after completing the previous production and assembly operations.

[0054] For the convenience of description, the following embodiments are described by taking an offline device according to an embodiment of the present application for performing offline operations on a battery module as an example.

[0055] Please refer to Figures 1 to 3 In the first aspect, the embodiment of the present application provides an offline device 1000, including a pallet loading device 100 and a material conveying device 200; the pallet loading device 100 includes a pallet grabbing mechanism 110 and a pallet transmission mechanism 120, and the pallet grabbing mechanism 110 is arranged on the peripheral side of the pallet transmission mechanism 120; the material conveying device 200 includes a material grabbing mechanism 210 and a material transmission mechanism 220, and the material grabbing mechanism 210 is used to grab the material transmitted by the material transmission mechanism 220 to the pallet transmitted by the pallet transmission mechanism 120.

[0056] The pallet loading device 100 is used to load and convey the pallet so that the materials can be placed on the pallet in sequence.

[0057] The pallet grabbing mechanism 110 is used to grab an empty pallet and place it on the pallet conveying mechanism 120; optionally, the pallet grabbing mechanism 110 includes but is not limited to a manipulator, a robot, a pneumatic clamp, a crane, etc.

[0058] The pallet transmission mechanism 120 is used to realize the transmission movement of the pallet, so that the pallet grabbing mechanism 110 grabs the material and puts it on the empty pallet being conveyed in sequence. The number of pallet transmission mechanisms 120 can be one or more than one. The pallet transmission mechanism 120 can adopt a variety of transmission mechanisms such as a conveyor belt and a double-speed chain. For example, in some specific embodiments, the pallet transmission mechanism 120 can be a transmission mechanism that transmits the pallet and the material along a specific path through a rolling structure such as a motor-driven roller or a roller.

[0059] Optionally, the pallet conveying mechanism 120 may be a conveying mechanism that performs unidirectional conveying in any direction; or, the pallet conveying mechanism 120 may also be a conveying mechanism that performs cyclic conveying in a ring shape. The pallet grabbing mechanism 110 is arranged on the peripheral side of the pallet conveying mechanism 120, so that the pallet grabbing mechanism 110 can grab an empty pallet and place it on the pallet conveying mechanism 120 on the peripheral side for conveying.

[0060] The material conveying device 200 is used to convey the material to the pallet loading device 100 and feed it onto the pallet to achieve stacking operation.

[0061] The material transmission mechanism 220 is used to transport the materials that have completed the previous assembly process; the number of the material transmission mechanism 220 can be one or more than one, for example, two, three, etc.; the material transmission mechanism 220 can adopt a variety of transmission mechanisms such as a conveyor belt and a double-speed chain. For example, in some specific implementations, the material transmission mechanism 220 can adopt a double-speed chain to transport the materials that have completed the previous assembly process to a preset position through the double-speed chain.

[0062] The material grabbing mechanism 210 is used to grab the material delivered by the material conveying mechanism 220 and put it onto the pallet conveyed by the pallet conveying mechanism 120, so as to achieve the purpose of removing the material and stacking it on the pallet; optionally, the material grabbing mechanism 210 includes but is not limited to a manipulator, a robot, a pneumatic clamp, a crane, etc.

[0063] It can be understood that the steps for implementing off-line operations through the above-mentioned pallet loading device 100 and material conveying device 200 are: use the pallet grabbing mechanism 110 to grab external empty pallets and put them into the pallet transmission mechanism 120 in turn, so that the pallets can be transported by the pallet transmission mechanism 120; at the same time, the material transmission mechanism 220 can transport the materials that have completed assembly processing, and the material grabbing mechanism 210 grabs the materials and sends them to the pallet transmitted by the pallet transmission mechanism 120, so as to achieve the purpose of stacking the materials on the pallet; and the pallet transmission mechanism 120 can also continue to transport the stacked pallets and materials for subsequent transfer operations.

[0064] The offline equipment 1000 provided in the embodiment of the present application utilizes a pallet loading device 100 to place pallets, and a pallet grabbing mechanism 110 grabs the pallet and places it on a pallet transmission mechanism 120 for transmission and movement. At the same time, a material conveying device 200 is utilized to place materials, and a material grabbing mechanism 210 grabs the materials transmitted on the material transmission mechanism 220 and places them on a pallet for transmission on the pallet transmission mechanism 120. Thus, the material grabbing mechanism 210 can continuously grab materials and place them on a pallet for transmission on the pallet transmission mechanism 120, while the pallet with materials placed on it continues to be transmitted through the pallet transmission mechanism 120, and empty pallets are continuously grabbed and placed by the pallet grabbing mechanism 110, which effectively improves the efficiency of placing materials on the pallet, and thus can effectively improve the offline efficiency of materials.

[0065] Please refer to Figure 2 and Figure 3 In some embodiments, the pallet transmission mechanism 120 has a first loading station 1201 and a second loading station 1202 arranged in sequence along the conveying direction X, the pallet grabbing mechanism 110 is used to grab the pallet and send it to the first loading station 1201, and the material grabbing mechanism 210 is used to grab the material and send it to the second loading station 1202.

[0066] It can be understood that the first loading station 1201 and the second loading station 1202 are respectively designated positions on the pallet conveying mechanism 120; the first loading station 1201 and the second loading station 1202 are arranged in sequence along the conveying direction X, so that for the pallet placed in the first loading station 1201, the pallet conveying mechanism 120 can convey the pallet forward and pass through the second loading station 1202, and the material grabbing mechanism 210 can grab the material and put it on the pallet conveyed to the second loading station 1202.

[0067] For example, in some specific embodiments, when the pallet conveying mechanism 120 is a conveying mechanism that performs unidirectional conveying in any direction, the pallet grabbing mechanism 110 can grab an empty pallet and load material at the first loading station 1201, and the material grabbing mechanism 210 can grab the material and place it on the pallet at the second loading station 1202. Thus, the material and the pallet are stacked at the second loading station 1202 and are driven by the material conveying mechanism 220 to continue to be conveyed forward for subsequent transfer operations.

[0068] Alternatively, in other specific embodiments, when the pallet conveying mechanism 120 is a conveying mechanism that performs cyclic conveying along a ring, the pallet grabbing mechanism 110 can grab an empty pallet and load material at the first loading station 1201, and the material grabbing mechanism 210 can grab material and place it onto the pallet at the second loading station 1202; since the pallet conveying mechanism 120 can drive the pallet and material for cyclic conveying, pallets can continue to be stacked on top of the material at the first loading station 1201, and materials can be placed again on the top pallet; when the stacking reaches a preset number of times, the stacked pallets and materials can be moved out of the pallet conveying mechanism 120 by other external devices for subsequent transfer operations.

[0069] With such arrangement, the action of placing the pallet into the pallet conveying mechanism 120 and the action of placing the material into the pallet are implemented at different locations, that is, the action of placing the pallet into the pallet conveying mechanism 120 and the action of placing the material into the pallet can be performed simultaneously, which effectively improves the rhythm of placing the material into the pallet, thereby further improving the material offline efficiency.

[0070] Please refer to Figure 3 In some embodiments, the pallet conveying mechanism 120 includes an annular conveyor belt 121, and the annular conveyor belt 121 has an offline workstation 1203; the offline equipment 1000 also includes a removal mechanism 300, which is arranged in the offline workstation 1203, and the removal mechanism 300 is configured to be able to move the pallet and the material out of the annular conveyor belt 121.

[0071] The annular conveyor belt 121 is used to drive the pallet to be circulated and transported in an annular manner for stacking the pallet and the material. It can be understood that the first loading station 1201 and the second loading station 1202 of the pallet transmission mechanism 120 are the first loading station 1201 and the second loading station 1202 on the annular conveyor belt 121.

[0072] The offline station 1203 refers to a designated position on the endless conveyor 121, and the pallet and the material can be moved out of the endless conveyor 121 in the offline station 1203 to complete the offline operation. It can be understood that the offline station 1203 can be one or more than one.

[0073] Optionally, the offline station 1203 may be any position on the endless conveyor belt 121; for example, the offline station 1203 may overlap with the first loading station 1201, whereby the pallet and the material are stacked in sequence, and after the pallet is stacked on top, the endless conveyor belt 121 may be directly moved out from the offline station 1203 (first loading station 1201);

[0074] Alternatively, the offline station 1203 may also overlap with the second loading station 1202, whereby the tray and the material are stacked in sequence, and after the material is stacked on top, the endless conveyor belt 121 may be directly removed from the offline station 1203 (second loading station 1202);

[0075] Alternatively, the off-line station 1203 can be arranged downstream of the first loading station 1201 along the conveying direction X of the endless conveyor belt 121 (e.g. Figure 3 As shown), the pallet and the material are stacked one after another, and after the pallet is finally stacked at the first loading station 1201, it is driven by the circular conveyor belt 121 and is continuously transported forward to the offline station 1203 and removed from the circular conveyor belt 121;

[0076] Alternatively, the off-line station 1203 can be located downstream of the second loading station 1202 along the conveying direction X of the circular conveyor belt 121, whereby the pallets and materials are stacked in sequence, and after the materials are finally stacked at the second loading station 1202, they are continued to be transported forward to the off-line station 1203 and moved out of the circular conveyor belt 121 via the drive of the circular conveyor belt 121.

[0077] The removal mechanism 300 is used to move the pallet and the material out of the circular conveyor 121; optionally, the removal mechanism 300 may include a driving member (cylinder, hydraulic cylinder, etc.) and a pushing structure (push plate, push block, etc.), and the driving member drives the pushing structure to push the pallet and the material in the offline workstation 1203, so that the pallet and the material are removed from the circular conveyor 121; or, the removal mechanism 300 may include a crane, and the crane is used to lift and move the pallet and the material in the offline workstation 1203 out of the circular conveyor 121; or, the removal mechanism 300 may also include a driving member (stepping motor, reduction motor, etc.) and a rolling structure (roller, drum, etc.), and the driving member drives the rolling structure to rotate, so that the pallet and the material are moved and moved out of the circular conveyor 121 through the rotation of the rolling structure.

[0078] With such an arrangement, the circular conveyor belt 121 can drive the pallets for circular transportation, whereby the pallets and materials can be stacked in a circular manner in sequence to achieve the purpose of stacking, and when the pallets and materials are stacked to a preset number of layers, they can be moved to the offline station 1203, and the removal mechanism 300 can move the stacked pallets and materials out of the circular conveyor belt 121 to achieve offline.

[0079] Please refer to Figure 3 In some embodiments, along the conveying direction X of the circular conveyor belt 121, the first loading station 1201, the offline station 1203 and the second loading station 1202 are arranged in sequence.

[0080] It can be understood that on the circular conveyor belt 121 , after the pallets are stacked at the first loading station 1201 , the pallets are moved to the offline station 1203 to be removed from the circular conveyor belt 121 .

[0081] In this way, along the conveying direction X of the circular conveyor belt 121, the pallets and materials can be stacked in sequence at the first loading station 1201 and the second loading station 1202 respectively to form stacked pallets and materials. After the pallets are stacked at the first loading station 1201, they are moved to the offline station 1203 to be offline. Thus, the stacked pallets and materials have a top layer of pallets, which can effectively cover and protect the materials.

[0082] Please refer to Figure 3 In some embodiments, the offline device 1000 further includes a counting sensor (not shown in the figure) for detecting the number of stacked trays, and the counting sensor is electrically connected to the removal mechanism 300 .

[0083] Among them, the counting sensor is used to detect the number of stacked pallets; optionally, the counting sensor can be a photoelectric sensor, and the sensing end of the photoelectric sensor can be directed to any point of the circular conveyor belt 121, for example, toward the offline workstation 1203. When the sensing end of the photoelectric sensor senses that the pallets and materials in the offline workstation 1203 have passed a preset number of times, the photoelectric sensor can send an electrical signal to the removal mechanism 300, so that the removal structure can remove the stacked preset number of pallets and materials; or, the counting sensor can also use an infrared sensor, a gravity sensor, a magnetic sensor, etc. The working principles of the above sensors are roughly the same as those of the photoelectric sensors, which will not be repeated here.

[0084] With such an arrangement, a counting sensor can be used to detect the number of stacked pallets. When the pallets are stacked to a preset number, the counting sensor can send an electrical signal to the removal mechanism 300, so that the removal mechanism 300 can remove the stacked pallets and materials, thereby achieving the purpose of stacking materials offline.

[0085] Please refer to Figure 3 In some embodiments, the removal mechanism 300 includes a removal drive 310 and a transfer roller group 320 arranged on the circular conveyor belt 121. The transfer roller group 320 is arranged in the offline workstation 1203. The output end of the removal drive 310 is connected to the transfer roller group 320 and is used to drive the pallet to move along the conveying direction X of the circular conveyor belt 121 or move out of the circular conveyor belt 121.

[0086] The removal drive member 310 is used to drive the transfer roller group 320 to rotate; optionally, the removal drive member 310 can adopt a stepping motor, a reduction motor, etc. to drive the rotating structure, and the removal drive member 310 can be installed on the fixed part (such as a base, a frame, etc.) of the ring conveyor 121 through fasteners.

[0087] The transfer roller set 320 is composed of a plurality of rollers arranged in parallel. The transfer roller set 320 is driven to rotate by the removal drive member 310 , so that the transfer roller set 320 can drive the pallet and the material to move.

[0088] It can be understood that the removal drive 310 can drive the transfer roller group 320 to rotate forward or reverse, so that the removal drive 310 can rotate forward to drive the pallet and materials to move along the conveying direction X of the circular conveyor belt 121 and continue to stack, or the removal drive 310 can reverse to drive the pallet and materials to move out of the circular conveyor belt 121.

[0089] In this arrangement, the removal drive member 310 can drive the transfer roller group 320 to rotate, so that the transfer roller group 320 arranged in the offline workstation 1203 can rotate to drive the pallet to move along the conveying direction X of the annular conveyor belt 121 and continue to stack, or the transfer roller group 320 rotates to drive the stacked pallets and materials to move out of the annular conveyor belt 121 and offline.

[0090] Please refer to Figure 3 In some embodiments, the offline device 1000 further includes an offline transmission mechanism 400 , which is connected to the annular conveyor belt 121 , and the removal mechanism 300 is configured to move the pallet and the material onto the offline transmission mechanism 400 .

[0091] The offline transmission mechanism 400 is used to transfer the pallets and materials offline; the number of the offline transmission mechanisms 400 can be one or more than one, and the offline transmission mechanism 400 can adopt various transmission mechanisms such as conveyor belts and double-speed chains.

[0092] It can be understood that when the stacking of the pallets and materials reaches a preset number of layers, the removal mechanism 300 can transfer the stacked pallets and materials to the offline transmission mechanism 400 and transfer them through the offline transmission mechanism 400.

[0093] With such arrangement, the removal mechanism 300 can move the stacked pallets and materials to the offline conveying mechanism 400, and the offline conveying mechanism 400 will transport them to a preset position, which effectively improves the convenience of material offline and transportation.

[0094] Please refer to Figure 3 In some embodiments, the annular conveyor belt 121 includes a first conveying section 1211 and a second conveying section 1212, the first conveying section 1211 and the second conveying section 1212 intersect and form a downline station 1203, and the downline conveying mechanism 400 is connected to the first conveying section 1211 and arranged in the extension direction of the first conveying section 1211.

[0095] It can be understood that the first transmission section 1211 and the second transmission section 1212 are respectively partial transmission sections of the annular conveyor belt 121; the first transmission section 1211 and the second transmission section 1212 intersect and form an offline workstation 1203, wherein the first transmission section 1211 and the second transmission section 1212 can intersect at the offline workstation 1203 to form an angle, for example, can form a vertical angle.

[0096] In this way, pallets are circulated on the circular conveyor belt 121 to stack materials and new pallets. When the stacked pallets and materials are transported from the second transmission section 1212 of the circular conveyor belt 121 to the intersection with the first transmission section 1211, the stacked pallets and materials are moved to the offline workstation 1203. If the stacking operation is not completed, the pallets and materials can continue to be transported by the first transmission section 1211. If the stacking operation is completed, the removal structure can move the stacked pallets and materials along the extension direction of the first transmission section 1211 and opposite to the conveying direction X of the first transmission to the offline transmission mechanism 400, so that the stacked pallets and materials are moved to the specified position through the offline transmission mechanism 400.

[0097] For example, in some specific embodiments, the circular conveyor belt 121 may be a rectangular ring structure, one of the rectangular sides of the circular conveyor belt 121 may be the first transmission section 1211, and the other three sides of the circular conveyor belt 121 may be the second transmission section 1212; the first transmission section 1211 and the second transmission section 1212 form a down-line station 1203 at one of their intersections, and the down-line station 1203 is connected to the first transmission section 1211 at the down-line station 1203, and the removal mechanism 300 may include a removal drive member 310 and a transfer roller group 320; thereby, in the process of stacking the pallet and the material , the driving member 310 is removed and drives the transfer roller group 320 to rotate forward to roll toward the first transmission section 1211, so that when the pallet and the material are transported from the second transmission section 1212 to the offline workstation 1203, they are transported to the first transmission section 1211 through the transfer roller group 320; after the stacking operation of the pallet and the material is completed, the driving member 310 is removed and drives the transfer roller group 320 to reverse to face away from the first transmission section 1211 and roll toward the offline transmission mechanism 400, so that when the pallet and the material are transported from the second transmission section 1212 to the offline workstation 1203, they are transported to the offline transmission mechanism 400 through the transfer roller group 320.

[0098] In this way, the offline transmission mechanism 400 is arranged in the extension direction of the first transmission section 1211, that is, the offline transmission mechanism 400 and the first transmission section 1211 are arranged in the same line, and the offline transmission mechanism 400 is connected to the offline workstation 1203. The removal mechanism 300 located at the offline workstation 1203 can more conveniently transfer pallets and materials to the first transmission section 1211 for continued stacking, or transfer them to the offline transmission mechanism 400 for offline transfer, thereby effectively improving the convenience of offline operations.

[0099] Please refer to Figure 3 In some embodiments, the circular conveyor belt 121 further has a protection station 1204 , and along the conveying direction X of the circular conveyor belt 121 , the second loading station 1202 , the protection station 1204 and the first loading station 1201 are arranged in sequence.

[0100] It can be understood that the protection station 1204 refers to a designated position on the circular conveyor belt 121; the protection station 1204 is used for the staff to perform protection operations on the materials, and to cover and protect the materials put in from the second loading station 1202 in the previous step, such as covering with a layer of protective cover, protective belt, protective film, etc., so as to reduce the probability of scratching the material when placing a pallet on the material in the first unloading station in the next step.

[0101] The conveying direction X of the second loading station 1202, the protection station 1204 and the circular conveyor belt 121 of the first loading station 1201 are arranged in sequence, so that after the second loading station 1202 puts the material, the protection operation can be performed in time at the protection station 1204.

[0102] With such arrangement, in the second loading station 1202, the material can be placed on the pallet, and in the process of the pallet and the material being transferred to the first loading station 1201, the material will first pass through the protection station 1204, so that the material on the top can be covered and protected at the protection station 1204, so as to reduce the probability of bumping and abrading the material when the pallets are stacked at the first loading station 1201.

[0103] Please refer to Figure 4 In some embodiments, the material conveying device 200 further includes a weighing platform 230 and a moving mechanism 240 . The weighing platform 230 is disposed on the periphery of the material conveying mechanism 220 . The moving mechanism 240 is used to move the material from the material conveying mechanism 220 to the weighing platform 230 .

[0104] It can be understood that the weighing platform 230 refers to a supporting structure with a weighing function; the number of the weighing platforms 230 can be one or more than one.

[0105] The moving mechanism 240 is used to transfer the material conveyed by the material conveying mechanism 220, so that the material is transferred to the weighing platform 230 for weighing, and then the material grabbing mechanism 210 grabs the weighed material to the tray conveying mechanism 120. The moving mechanism 240 includes but is not limited to structures such as a transverse machine and a crane that can realize the movement and transfer of materials. The number of the moving mechanisms 240 can be one or more than one.

[0106] With such an arrangement, the material transported by the material transmission mechanism 220 can be moved to the weighing platform 230 through the moving mechanism 240. After the material is weighed by the weighing platform 230, it is grabbed by the material grabbing mechanism 210 and placed on the pallet, thereby realizing the weighing operation of the material before the material goes offline.

[0107] Please refer to Figure 3 and Figure 4In some embodiments, the pallet loading device 100 further includes a lifting mechanism (not shown in the figure), which is disposed in the second loading station 1202 and is used to lift the pallet in the second loading station 1202 .

[0108] The lifting mechanism is used to lift the pallet in the second loading station 1202 in the second loading station 1202 .

[0109] The lifting mechanism may include a lifting drive (such as a cylinder, a hydraulic cylinder, etc.) and a lifting structure. The lifting drive can drive the lifting structure to perform lifting movements, so that the lifting structure can drive the pallet to be lifted and lowered.

[0110] With such arrangement, in the second loading station 1202 , the lifting mechanism can lift the pallet, so that the material grabbing mechanism 210 can position the material and place it on the pallet, thereby effectively improving the accuracy of the material grabbing mechanism 210 in placing the material.

[0111] Please refer to Figures 2 to 4 In some embodiments, the offline equipment 1000 further includes a hoisting mechanism 250 , which is arranged around the material transmission mechanism 220 .

[0112] The hoisting mechanism 250 is a device used for lifting, transporting and hanging objects, which is usually composed of a crane, a wire rope or chain, a hook, etc.

[0113] In this way, by arranging the lifting mechanism 250 on the surrounding side of the material transmission mechanism 220, when the pallet loading device 100 or the material grabbing mechanism 210 fails, the material can be lifted off the line by the lifting mechanism 250, thereby reducing the probability of being unable to be taken off the line due to failure.

[0114] Below, a specific implementation of the offline device 1000 will be described by taking a battery module as an example.

[0115] In this embodiment, the offline equipment 1000 includes a pallet loading device 100, a material conveying device 200 and an offline transmission mechanism 400; the pallet loading device 100 includes a pallet grabbing mechanism 110, a lifting mechanism and an annular conveyor belt 121 with a rectangular ring structure in the conveying path, and the annular conveyor belt 121 is sequentially provided with a first loading station 1201, an offline station 1203, a second loading station 1202 and a protection station 1204 along the conveying direction X, the pallet grabbing mechanism 110 is used to grab an external empty pallet and put it into the first loading station 1201, and the lifting mechanism is arranged in the second loading station 1202; a removal mechanism 300 is arranged in the offline station 1203, and the removal mechanism 300 includes a removal drive 310 and a transfer roller group 320, the removal drive 310 is connected to the transfer roller group 320, and the transfer roller group 320 is arranged in the offline station 1203.

[0116] Among them, the off-line station 1203 is arranged at a right angle in the conveying path of the rectangular ring structure of the circular conveyor belt 121. At the same time, the off-line transmission mechanism 400 is connected to the off-line station 1203 of the circular conveyor belt 121, and the off-line transmission mechanism 400 and the conveying path on any side of the above-mentioned right angle formed by the circular conveyor belt 121 are colinearly arranged; thus, the removal mechanism 300 can drive the tray and the battery module in the off-line station 1203 to continue to be transmitted along the conveying direction X of the circular conveyor belt 121, or drive the tray and the battery module to move in the opposite direction to the off-line transmission mechanism 400 for off-line transfer.

[0117] The material conveying device 200 includes a material grabbing mechanism 210, a material transmission mechanism 220, a hoisting mechanism 250, a weighing platform 230 and a moving mechanism 240. The moving mechanism 240 can adopt a transverse moving machine, which is arranged on the side of the material transmission mechanism 220 and is used to move the battery module on the material transmission mechanism 220 to the weighing platform 230 for weighing. The material grabbing mechanism 210 is used to grab the battery module that has completed the weighing operation on the weighing platform 230 and place it into the second loading station 1202; the hoisting mechanism 250 is used to be arranged on the side of the material transmission mechanism 220 to provide backup when any structure in the material grabbing mechanism 210 or the subsequent pallet loading device 100 fails.

[0118] When the off-line equipment 1000 is working, the pallet grabbing mechanism 110 grabs the external empty pallet and puts it into the first loading station 1201. The pallet first passes through the off-line station 1203. If the number of stacking layers of the pallet does not reach the preset value, it continues to be transported forward to the second loading station 1202. The lifting mechanism in the second loading station 1202 can lift the pallet, and the battery module is grabbed by the material grabbing mechanism 210 and placed in the lifted pallet; then the lifting mechanism lowers the pallet with the battery module placed, and the pallet conveying mechanism 120 continues to convey it forward to the protection station 1204, and the staff covers the top battery module with a layer of plastic protective film; then the pallet conveying mechanism 120 continues to convey it forward to the first loading station 1201, and the pallet grabbing mechanism 110 grabs the external empty pallet and puts it into the first loading station 1201, so that the empty pallet can be covered on the top of the battery module to achieve stacking; then the pallet conveying mechanism 120 continues to convey it forward.

[0119] According to the above steps, the pallets and materials are circulated and transported to achieve stacking. When the pallet stacking reaches a preset number, the pallet conveying mechanism 120 conveys the pallet and the battery module to the offline workstation 1203, and the removal mechanism 300 drives the pallet and the battery module to be transferred to the offline conveying mechanism 400, and the offline transfer is carried out through the offline conveying mechanism 400.

[0120] In a second aspect, an embodiment of the present application further provides a battery production line, including the offline equipment 1000 as described above.

[0121] The battery production line provided in the embodiment of the present application includes the above-mentioned offline equipment 1000. Based on the high offline efficiency of the above-mentioned offline equipment 1000, the production efficiency of the battery production line is also effectively improved.

[0122] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
