[0046] Techniques and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques and devices should be regarded as part of the specification.

[0047] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0048] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0049] An embodiment of the present application provides a feeding device. Through the collaborative work of a conveying mechanism 1, a pushing mechanism 2, and a blowing mechanism 3, the feeding device realizes the automated process of successively taking out the sheet materials stacked in a stack from a magazine 5 and moving them to a specified grasping position. For example, the sheet materials include, but are not limited to, battery wafers.

[0050] Referring to Figures 1-4 , the feeding device includes: a conveying mechanism 1, having a feeding position A and a discharging position B, the conveying mechanism 1 is used for conveying the magazine 5 located at the feeding position A, the magazine 5 includes a pallet 52 and a supporting member, the pallet 52 is movably arranged on the supporting member, the pallet 52 is used for carrying the sheet materials stacked in a stack, and the supporting member is provided with a second avoidance hole;

[0051] The conveying mechanism 1 includes a first conveying member 10, and the first conveying member 10 is provided with a first avoidance hole;

[0052] A pushing mechanism 2, the pushing mechanism 2 is located below the first conveying member 10 and corresponds to the discharging position B, the pushing mechanism 2 penetrates through the first avoidance hole and the second avoidance hole to push the pallet 52, so that the uppermost material on the pallet 52 is continuously moved to the target position;

[0053] A blowing mechanism 3, the blowing mechanism 3 is arranged on the conveying mechanism 1 and is located at the discharging position B, the blowing mechanism 3 is used for blowing the material located at the target position to the grasping position, and the height of the grasping position in the vertical direction is higher than that of the target position.

[0054] In this embodiment, the feeding device includes a conveying mechanism 1, and the conveying mechanism 1 is responsible for conveying the magazine 5 containing the sheet materials stacked in a stack from the feeding position A to the discharging position B.

[0055] Referring to Figure 1 , the magazine 5 includes a plurality of baffles 50 arranged in the vertical direction, and the plurality of baffles 50 enclose a preset space, and the preset space matches the size of the material; the magazine 5 further includes a bottom plate 51, the bottom plate 51 is located in the preset space and is fixedly connected to the plurality of baffles 50. In this embodiment, the baffles 50 and the bottom plate 51 constitute the supporting member for supporting the pallet 52.

[0056] It should be noted that the supporting member provided in the embodiment of the present application is a preferred structure for supporting the pallet 52. Those skilled in the art can adjust the structure of the supporting member according to parameters such as the material specifications and dimensions.

[0057] It is worth mentioning that the material box 5 further includes a pallet 52, and the pallet 52 is movably arranged on the bottom plate 51 to facilitate the pushing mechanism 2 to push the pallet 52. And a second avoidance hole is also opened on the supporting member, specifically, the second avoidance hole can be opened on the bottom plate 51. When the pushing mechanism 2 needs to work, the pushing mechanism 2 will sequentially penetrate through the first avoidance hole and the second avoidance hole to accurately push the pallet 52.

[0058] Such a design enables the pushing mechanism 2 to effectively push the materials on the pallet 52 to the target position, providing great convenience for subsequent grasping and handling operations. Exemplarily, the first avoidance hole is a first through hole opened on the first conveying member 10, and the second avoidance hole is a second through hole opened on the bottom plate 51.

[0059] Refer to Figure 1 , the feeding position A is the starting point where the material box 5 begins its conveying process and is also the starting point of the entire feeding operation cycle. At the feeding position A, the material box 5 is placed on the conveying mechanism 1 and then conveyed to the discharging position B for subsequent pushing and blowing operations. Optionally, a device for grasping the material box 5 can be additionally provided near the feeding position A to load the material box 5 in the material frame onto the feeding position A of the conveying mechanism 1.

[0060] Refer to Figure 1 , the discharging position B is the end point where the material box 5 completes the material conveying process on the conveying mechanism 1 and is also the starting point where the pushing mechanism 2 and the blowing mechanism 3 start to work. After the material box 5 completes the material conveying on the conveying mechanism 1, the conveying mechanism 1 continues to convey the empty material box to ensure the smooth progress of the entire material conveying process.

[0061] In the automated process of the entire feeding device, the discharging position B is a key control point. When the material box 5 is conveyed to the discharging position B, the pushing mechanism 2 starts to work and pushes the material box 5 upward through the first avoidance hole of the conveying mechanism 1. At the same time, the blowing mechanism 3 is also ready to blow the pushed-out material to the grasping position.

[0062] Among them, the discharging position B closely cooperates with the pushing mechanism 2 to ensure that the pushing mechanism 2 can accurately push out the topmost layer of materials in the pallet 52 and move them to the target position. During this process, the conveying mechanism 1 remains stationary to enable the pushing mechanism 2 to work stably.

[0063] Refer to Figures 1-4 , the conveying mechanism 1 includes a first conveying member 10, and the first conveying member 10 is provided with a first avoidance hole to facilitate the pushing mechanism 2 to pass through and perform the pushing operation. For example, the first conveying member 10 is provided with a first avoidance hole at the discharging position B to enable the pushing mechanism 2 to penetrate through the first avoidance hole of the conveying mechanism 1 and push the pallet 52 of the material box 5 upward.

[0064] In this embodiment, the loading device further includes a pushing mechanism 2, which is located below the first conveying component 10 and corresponds to the discharging position B. The pushing mechanism 2 penetrates through the first conveying component 10 and the bottom plate 51 through the first avoidance hole and the second avoidance hole, and is used to push up the pallet 52 upward, so that the uppermost material in the pallet 52 moves to a preset target position.

[0065] The pushing mechanism is used to push up the uppermost material in the cartridge 5 to the target position. The "uppermost material" refers to the topmost layer of the sheet materials stacked in the cartridge 5. The uppermost material does not refer to a specific material. As the materials are pushed and blown, the uppermost material is continuously updated.

[0066] For example, under the synergistic action of the pushing mechanism 2 and the blowing mechanism 3, the material that was originally the uppermost layer in the pallet 52 is blown to the grasping position. Then, the material that was originally in the second layer (the lower layer of the material that was originally the uppermost layer) in the pallet 52 is updated to the uppermost material. Therefore, when the pushing mechanism 2 pushes the uppermost material once, under the synergistic action of the blowing mechanism 3, it is also a process of updating the uppermost material. And under the synergistic action of the pushing mechanism 2 and the blowing mechanism 3, the updated uppermost material is placed at the target position.

[0067] In addition, it should be noted that under the synergistic action of the pushing mechanism 2 and the blowing mechanism 3, the pushing mechanism 2 pushes a piece of the uppermost material, and then the blowing mechanism 3 blows the uppermost material to the grasping position; when the blowing mechanism 3 blows the uppermost material to the grasping position, the pushing mechanism 2 can push another piece of the uppermost material. The pushing process and the blowing process of the material are continuous processes, so that the uppermost material on the pallet 52 continuously appears at the target position.

[0068] The target position is within the working range of the pushing mechanism 2 and corresponds to the discharging position B and the installation position of the blowing mechanism 3. When the pushing mechanism 2 is started, the pushing mechanism 2 will push and move the uppermost material in the cartridge 5 to this target position so that the blowing mechanism 3 can blow the material.

[0069] For example, after the pushing mechanism 2 is started, it pushes the material that was originally the uppermost layer in the cartridge 5 to the target position, and then the blowing mechanism 3 blows the material to the grasping position. After the material is grasped by the grasping device 6, the pushing mechanism 2 continues to push up the cartridge 5 so that the material that was originally in the second layer (the lower layer of the material that was originally the uppermost layer) is pushed to the target position.

[0070] In this embodiment, the feeding device further includes a blowing mechanism 3, which is ingeniously arranged on the conveying mechanism 1, and its position is carefully selected at the discharging position B. Such a design layout enables the blowing mechanism 3 to blow the material immediately after the material is conveyed to the discharging position B. In addition, the blowing mechanism 3 is installed on the conveying mechanism 1, which also makes the integration degree of the feeding device higher and is conducive to reducing the space occupied by the feeding device.

[0071] When the conveying mechanism 1 accurately conveys the material to the discharging position B, the blowing mechanism 3 will be activated to blow gas to the material. This action helps to separate adjacent materials, especially when the materials exist in a stacked form, enabling the materials to move to the next processing or handling step individually and smoothly.

[0072] Specifically, after the topmost material is pushed to the target position, the blowing mechanism 3 is activated. The blowing mechanism 3 blows up the topmost material located at the target position and further moves it to the grasping position for subsequent grasping or handling operations.

[0073] The blowing mechanism 3 is used to blow up the topmost material to the grasping position. When the topmost material is at the grasping position, the whole topmost material floats up and is separated from the adjacent lower material, so that when the grasping device 6 grasps the material at the grasping position, other materials will not be damaged.

[0074] The height of the grasping position in the vertical direction is higher than that of the target position, or the grasping position can be beside the target position, specifically depending on the height to which the blowing mechanism 3 blows the material and the operating range of the grasping device. Preferably, the height of the grasping position in the vertical direction is higher than that of the target position. After the blowing mechanism 3 blows up the topmost material to a certain height, the grasping device 6 will quickly move to the grasping position and accurately grasp the material through its grasping device 6 (such as a clamp, a suction cup, etc.) and move it to the next processing or handling step.

[0075] Therefore, in this embodiment, through the coordinated work of the conveying mechanism 1, the pushing mechanism 2 and the blowing mechanism 3, the feeding device can efficiently realize the automatic feeding process of the material, and at the same time avoid the situation of material damage during the grasping process.

[0076] In an exemplary embodiment, referring to Figure 1 and Figure 5 , the blowing mechanism 3 includes two main parts, an installation part 30 and a blowing part 31. The installation part 30 is firmly arranged on the conveying mechanism 1, ensuring the overall stability and reliability of the blowing mechanism 3. The blowing part 31 is installed on the installation part 30, and such a design enables the blowing part 31 to flexibly align with and act on the material to achieve an efficient blowing separation effect.

[0077] The close combination of the installation part 30 and the conveying mechanism 1 not only ensures the stability of the blowing mechanism 3 during operation, but also enables the blowing operation to closely cooperate with the conveying action of the conveying mechanism 1, ensuring that the material can be immediately blown after being pushed when it reaches the discharging position B.

[0078] In a specific embodiment, the conveying mechanism 1 further includes side plates 12, which are cleverly arranged along the conveying direction of the conveying mechanism 1 and are located on one side of the first conveying component 10, providing a stable support platform for the installation part 30.

[0079] For example, the installation part 30 can be fixedly arranged on the side plates 12. Such a design layout not only ensures the stability and reliability of the installation part 30, but also enables the blowing mechanism 3 to be closely integrated with the conveying mechanism 1, realizing seamless collaborative work between the two.

[0080] The existence of the side plates 12 also provides additional structural strength and rigidity to the conveying mechanism 1, enabling the entire conveying mechanism 1 to maintain a stable operating state during operation and effectively resist external interference and vibration.

[0081] In one embodiment, referring to Figure 5 , the blowing part 31 of the blowing mechanism 3 includes a bracket 311 and at least one group of air knife assemblies 312, and the air knife assemblies 312 are arranged on the bracket 311;

[0082] Each group of the air knife assemblies 312 includes two blowing air knives 3121, and the two blowing air knives 3121 are arranged at intervals in the conveying direction of the conveying mechanism 1, and the interval distance matches the size of the material box 5 in the conveying direction of the conveying mechanism 1.

[0083] In this embodiment, the blowing part 31 includes a bracket 311 and at least one group of air knife assemblies 312. Referring to Figure 5 , the blowing part 31 includes a bracket 311 and two groups of air knife assemblies 312. In this way, the blowing part 31 can blow the materials in two material boxes 5 simultaneously, improving the feeding efficiency of the feeding device. For example

[0084] Specifically, the bracket 311 serves as the support structure of the air knife assemblies 312, ensuring the stability and reliability of the air knife assemblies 312. The air knife assemblies 312 are the core of the blowing part 31, responsible for generating high-speed airflows to achieve blowing separation of the materials.

[0085] Each group of air knife assemblies 312 includes two blowing air knives 3121, and the two blowing air knives 3121 are arranged at intervals in the conveying direction of the conveying mechanism 1. This way of arranging at intervals enables the two blowing air knives 3121 to act on different positions of the material respectively, thus achieving a more comprehensive blowing separation effect. Referring toFigure 5 The air blowing part 31 includes two groups of air knife assemblies 312. One group of air knife assemblies 312 includes a first air blowing knife 3121a and a second air blowing knife 3121b, and the first air blowing knife 3121a and the second air blowing knife 3121b are arranged oppositely. The other group of air knife assemblies 312 includes a third air blowing knife 3121c and a fourth air blowing knife 3121d, and the third air blowing knife 3121c and the fourth air blowing knife 3121d are arranged oppositely.

[0086] Specifically, the spacing distance between the two air blowing knives 3121 is carefully designed to match the size of the magazine 5 in the conveying direction of the conveying mechanism 1. Such a design ensures that the air blowing knives 3121 can accurately align with the materials in the magazine 5 and provide an effective air blowing effect when the materials pass through.

[0087] In one embodiment, referring to Figure 5 the air blowing knife 3121 includes a knife handle 31211 and a knife body 31212 connected to the knife handle 31211;

[0088] A first cavity is formed inside the knife handle 31211, a second cavity is formed inside the knife body 31212, the first cavity and the second cavity are communicated, and the knife handle 31211 is provided with an air inlet 31213 of the first cavity, and the knife body 31212 is provided with an air outlet 31214 communicated with the second cavity.

[0089] In this embodiment, the air blowing knife 3121 mainly includes two parts: a knife handle 31211 and a knife body 31212 connected to the knife handle 31211. The knife handle 31211, as the supporting part of the air knife, not only provides a stable structure but also is responsible for introducing the air flow into the air knife. The knife body 31212 is the working part of the air knife, which is responsible for spraying the air flow in a high-speed and concentrated form to achieve the air blowing separation of the materials.

[0090] Inside the knife handle 31211, a first cavity is designed. This first cavity serves as a channel for the air flow and is responsible for introducing the external air flow into the air knife. In order to connect with the external air source, the knife handle 31211 is also provided with an air inlet 31213 of the first cavity. In this way, when the external air source provides the air flow, the air flow can smoothly enter the first cavity through the air inlet 31213.

[0091] Inside the tool body 31212, a second cavity communicating with the first cavity is formed. This second cavity serves as a further passage for the air flow, responsible for guiding the air flow in the first cavity to the air outlet 31214 of the tool body 31212. In order to generate a high-speed and concentrated air flow on the tool body 31212, an air outlet 31214 communicating with the second cavity is carefully provided on the tool body 31212. In this way, when the air flow enters the second cavity, it can be ejected through the air outlet 31214 in a high-speed and concentrated form to achieve blowing separation of the material.

[0092] In one embodiment, referring to Figure 5 , the air outlets 31214 of the two blowing air knives 3121 of each group of the air knife assemblies 312 are arranged oppositely.

[0093] In this embodiment, in each group of air knife assemblies 312, the air outlets 31214 of the two blowing air knives 3121 are specially designed to be arranged oppositely, which means that when the blowing air knives 3121 work, the air flows generated by the two air outlets 31214 will correspond to each other and act on the material together.

[0094] This ensures that the air flow can act evenly on both sides of the material, thus more effectively achieving blowing separation. In addition, the oppositely arranged air flows can complement each other, enhancing the blowing effect and making it easier for the material to be separated and moved. Finally, this design also helps to reduce the impact force of the air flow on the material.

[0095] For example, referring to Figure 5 , the air outlet 31214 of the first blowing air knife 3121a and the air outlet 31214 of the second blowing air knife 3121b are arranged oppositely, and the air outlet 31214 of the third blowing air knife 3121c and the air outlet 31214 of the fourth blowing air knife 3121d are arranged oppositely.

[0096] In an alternative embodiment, referring to Figure 5 , an intake valve 31215 is provided at the intake port 31213.

[0097] In this embodiment, the main function of the intake valve 31215 is to control the on-off of the air flow, thereby achieving precise control of the operation of the blowing air knife 3121.

[0098] By switching the intake valve 31215, it is possible to flexibly control when the blowing air knife 3121 starts or stops working. When it is necessary to blow and separate the material, the intake valve 31215 is opened, and the air flow smoothly enters the inside of the blowing air knife 3121 through the intake port 31213 and is ejected through the air outlet 31214 in a high-speed and concentrated form to achieve blowing separation of the material. When blowing is not required, the intake valve 31215 is closed, the air flow is cut off, and the blowing air knife 3121 stops working.

[0099] In an exemplary embodiment, referring to Figure 5 , the air outlet 31214 is a plurality of air holes formed in the blade body 31212, or the air outlet 31214 is a plurality of air gaps formed in the blade body 31212.

[0100] In this embodiment, the air outlet 31214 can be a plurality of air holes formed in the blade body 31212. For example, these air holes are evenly distributed on the blade body 31212. When the air flow enters the air knife 3121, it will be ejected through these air holes in a high-speed and concentrated form to achieve the blowing separation of the material.

[0101] Or the air outlet 31214 can be a plurality of air gaps formed in the blade body 31212. These air gaps are also evenly distributed on the blade body 31212, and the air gaps can provide a larger air flow outlet area. When the air flow enters the air knife 3121, it will be ejected through these air gaps in a wider and more uniform air flow form to also achieve the blowing separation of the material. Referring to Figure 5 , the air outlet 31214 is a plurality of air gaps formed in the blade body 31212.

[0102] In one embodiment, referring to Figure 5 , the position of the air knife 3121 disposed on the bracket 311 is adjustable.

[0103] In this embodiment, different materials have differences in shape, size, weight, etc., and the requirements for the position of the air knife 3121 are also different. The adjustable position design enables the air knife 3121 to be adjusted according to the actual situation of the material to ensure that the air flow can accurately act on the material and improve the effect of blowing separation.

[0104] In a specific embodiment, referring to Figure 5 , the bracket 311 includes a main body and an adjustment plate 3111. The adjustment plate 3111 is disposed on the main body, and an installation area is defined between the adjustment plate 3111 and the main body. The installation position of the air knife 3121 in this installation area is adjustable. For example, a plurality of installation holes are provided on the adjustment plate 3111. When the air knife 3121 is installed in cooperation with different installation holes, the installation position of the air knife 3121 in the installation area will be different.

[0105] It should be noted that the ways to adjust the position of the air knife 3121 include but are not limited to the above-defined ways. For example, the air knife 3121 can also be slidably disposed on the bracket 311.

[0106] In one embodiment, referring to Figure 5, each set of the air knife assemblies 312 further includes a position sensor 313 for detecting whether the topmost material is blown up to the grasping position;

[0107] The position sensor 313 is disposed on the blade body 31212 of one of the blowing air knives 3121 in the air knife assembly 312.

[0108] In this embodiment, the air knife assembly 312 further includes a position sensor 313. For example, the position sensor 313 includes but is not limited to a photoelectric sensor.

[0109] The core function of the position sensor 313 is to detect in real time whether the topmost material has been successfully blown up to the preset grasping position by the blowing air knife 3121.

[0110] To ensure the accuracy and efficiency of detection, the position sensor 313 is cleverly installed on the blade body 31212 of one of the blowing air knives 3121 in the air knife assembly 312. Such a design enables the position sensor 313 to be closely close to the material, so as to more accurately capture the position change of the material. For example, referring to Figure 5 , the first blowing air knife 3121a and the second blowing air knife 3121b constitute a set of air knife assemblies 312, and a position sensor 313 is disposed on the first blowing air knife 3121a. The third blowing air knife 3121c and the fourth blowing air knife 3121d constitute another set of air knife assemblies 312, and a position sensor 313 is also disposed on the fourth blowing air knife 3121d.

[0111] In the actual working process, when the blowing air knife 3121 starts to work, an air flow will be generated, and this air flow will act on the material to blow the material up to the grasping position. At the same time, the position sensor 313 is continuously monitoring the position of the material. Once the material is successfully blown up and reaches the grasping position, the position sensor 313 will immediately send a signal to the grasping device 6 so that the grasping device 6 can grasp the material.

[0112] In one embodiment, referring to Figures 1-3 , the feeding device further includes a limiting mechanism, and the limiting mechanism is located below the first conveying component 10 and is telescopically disposed on the front side and / or the rear side of the blowing mechanism 3, where the front side is the front of the conveying direction of the conveying mechanism 1, and the rear side is the rear of the conveying direction of the conveying mechanism 1.

[0113] In this embodiment, the limiting mechanism is arranged below the first conveying component 10, and the limiting mechanism can be telescopically disposed on the front side or the rear side of the blowing mechanism 3, or simultaneously disposed on the front side and the rear side. Such a design enables the limiting mechanism to be flexibly adjusted as needed.

[0114] Here, the "front side" refers to the front in the conveying direction of the conveying mechanism 1, and the "rear side" refers to the rear in the conveying direction of the conveying mechanism 1. The main function of the limiting mechanism is to ensure that the material can be kept in a predetermined position during the conveying process. Specifically, the main function of the limiting mechanism is to ensure the conveying position of the cartridge 5 located between the air blowing mechanisms 3.

[0115] After the cartridge 5 reaches between the air blowing mechanisms 3 (which can also be understood as the cartridge 5 reaching the discharging position B), the limiting mechanism located on the front side of the air blowing mechanism 3 extends to limit the cartridge 5, so as to prevent the conveying position of the cartridge 5 from exceeding the discharging position B. And the limiting mechanism located on the rear side of the air blowing mechanism 3 also extends to limit the cartridge 5, so as to prevent the rear cartridge 5 from affecting the conveying position of the cartridge 5 at the discharging position B. In addition, it can also further position and guide the material after the material passes through the air blowing mechanism 3 to ensure that the material can continue to move forward stably.

[0116] In one embodiment, referring to Figure 1 , a fourth avoidance hole is formed in the edge of the cartridge 5, and a third avoidance hole is also formed in the first conveying member 10;

[0117] When the cartridge 5 is conveyed to the discharging position B, the limiting mechanism sequentially penetrates through the third avoidance hole and the fourth avoidance hole to limit the cartridge 5 at the discharging position B.

[0118] In this embodiment, a fourth avoidance hole is formed in the edge of the cartridge 5. At the same time, a third avoidance hole is also formed in the first conveying member 10. The design of these two avoidance holes is not arbitrary, but has its unique functions and roles. For example, the fourth avoidance hole can be a semi-circular hole.

[0119] When the cartridge 5 is conveyed to the discharging position B, the limiting mechanism begins to play its key role. The limiting mechanism will sequentially penetrate through the third avoidance hole and the fourth avoidance hole and finally reach the front side and / or the rear side of the discharging position B. Here, the limiting mechanism will accurately limit the cartridge 5 to ensure that it remains in the correct position and will not shift or move due to external factors.

[0120] In one embodiment, referring to Figure 1 , the limiting mechanism includes a first driving part and a limiting part, and the first driving part is connected to the limiting part to drive the limiting part to extend or retract.

[0121] In this embodiment, the limiting mechanism mainly includes a first driving part and a limiting part.

[0122] The first driving part serves as the power source of the limiting mechanism and is responsible for providing the necessary driving force. It is closely connected to the limiting component and can drive the limiting component to extend or retract through precise mechanical or electronic control.

[0123] The limiting component is the working body of the limiting mechanism. It directly acts on the cartridge 5 to effectively limit it. When the first driving part provides the driving force, the limiting component will extend according to the instruction and enter the preset working position to firmly limit the cartridge 5. When it is necessary to release the limit, the first driving part will drive the limiting component to retract, making it leave the working position and no longer limit the cartridge 5.

[0124] In one embodiment, referring to Figure 1 , the pushing mechanism 2 includes a second driving part, a transmission component and an execution component. The second driving part drives the transmission component to move, and the execution component realizes linear motion in the vertical direction by connecting with the transmission component.

[0125] In this embodiment, the pushing mechanism 2 includes a second driving part, a transmission component and an execution component.

[0126] The second driving part serves as the power source of the pushing mechanism 2 and is responsible for providing the necessary driving force. When it is necessary to execute the pushing action, the second driving part will start to work and generate the driving force.

[0127] The transmission component is responsible for transmitting the driving force generated by the second driving part to the execution component. It converts the driving force into the required motion form of the execution component through a precise mechanical structure or electronic control.

[0128] The execution component is the working body of the pushing mechanism 2. It directly contacts the cartridge 5 and performs a pushing operation on it. By connecting with the transmission component, the execution component can realize linear motion in the vertical direction. When the driving force is transmitted by the transmission component, the execution component will perform linear motion in the vertical direction to complete the pushing task.

[0129] In a specific implementation, referring to Figure 1 and Figure 2 , the second driving part can be a stepping motor, the transmission component can be a belt assembly, for example, the belt assembly includes belt pulleys and a conveyor belt. The execution component can be a lead screw, etc.

[0130] In one embodiment, referring to Figure 1 , the

[0131] In one embodiment, referring to Figures 1-4, the conveying mechanism 1 further includes a second conveying member 11, and a transfer mechanism 13 is provided between the second conveying member 11 and the first conveying member 10. The transfer mechanism 13 is used to transfer the empty material boxes on the first conveying member 10 to the second conveying member 11.

[0132] In this embodiment, in addition to the previously mentioned first conveying member 10, the conveying mechanism 1 further includes a second conveying member 11. And between these two conveying members, a transfer mechanism 13 is also provided.

[0133] The main function of the transfer mechanism 13 is to transfer empty material boxes between the first conveying member 10 and the second conveying member 11. When the material in the material box 5 on the first conveying member 10 is taken away, the transfer mechanism 13 will transfer this empty material box to the second conveying member 11. In this way, the second conveying member 11 can convey the empty material box away for subsequent recycling, cleaning or other processing.

[0134] In one embodiment, refer to Figures 1-4 , the first conveying member 10 and the second conveying member 11 are arranged in the vertical direction.

[0135] In this embodiment, the first conveying member 10 and the second conveying member 11 are not on the same horizontal plane, and the first conveying member 10 and the second conveying member 11 form a distribution in the vertical direction.

[0136] This arrangement makes the entire conveying mechanism 1 more reasonably utilized in space. In addition, the vertical arrangement of the first conveying member 10 and the second conveying member 11 also helps the smooth flow of materials. When the materials are conveyed on the first conveying member 10, they can be easily transferred to the second conveying member 11 at a different height through the transfer mechanism 13 to continue the subsequent conveying or processing process. Such a design avoids the complex transfer of materials in the horizontal direction, simplifies the conveying process, and improves the accuracy and stability of conveying.

[0137] The embodiment of the present application also provides a battery cell production device. The battery cell production device includes the feeding device as described in the first aspect. For example, the battery cell production device can be a battery cell string welding machine.

[0138] In one embodiment, the battery cell production device further includes a grasping device 6. The grasping device 6 is used to grasp the materials at the grasping position, and the grasping device 6 is located near the discharging position B of the conveying mechanism 1.

[0139] In this embodiment, the battery cell production equipment further includes a gripping device 6, which is arranged near the discharging position B of the conveying mechanism 1. The main task of the gripping device 6 is to accurately grip the material located at the gripping position. When the material has undergone a series of processes by the feeding device, such as being blown up by the air blowing mechanism 3 and reaching the preset gripping position, the gripping device 6 will quickly and accurately grip it.
