[0089] At present, various processes and equipment are used in the production or packaging processing of power lithium battery modules. For the large packaging loading area of ​​the loading system in the relevant technology, personnel are often required to use forklifts and other conveying equipment to allow the material packaging containing battery cells to enter the loading area; and then use a gripping device in the form of a robotic arm to transfer the battery cells to another conveyor line for subsequent assembly to form battery modules.

[0090] Since the feeding system involves various processes and equipment, the feeding efficiency needs to be further improved.

The loading and buffering device 120 may be configured as a conveying structure such as a conveyor belt or a roller bed.

[0094] The battery grabbing area 200 can be set as a workshop floor or a second receiving platform. The battery grabbing area 200 can also be set as a conveying structure such as a conveyor belt or a roller bed. Figure 1 It can be understood that, in this embodiment, the preset conveying direction is formed by the conveying direction of the loading and feeding device 110 (if the loading and feeding device 110 is capable of conveying) and the conveying direction of the loading buffer device 120.

[0095] The conveying equipment for conveying the material packages to the upper material feeding device 110 may be configured as a forklift or an AGV (Automated Guided Vehicle) or the like.

[0096] In addition, the support member 610 can be configured as a supporting structure such as foam and the like in a plate shape as a whole, and a plurality of receiving grooves can be provided on the support member 610 to respectively receive each battery cell 620.

[0099] The first opening and closing detection device is electrically connected to the loading buffer device 120, which can be understood as the first opening and closing detection device being able to transmit an electrical signal to the loading buffer device 120. The loading buffer device 120 can be set as a roller bed, and when receiving the above-mentioned door closing signal, the loading buffer device 120 can accommodate the material packaging from the loading and feeding device 110 by rotating the roller shaft of the roller bed.

[0101] Correspondingly, based on the above-mentioned embodiments of the feeding system, the present application also proposes a method for using the feeding system, which can reduce the need to wait for material packaging and is conducive to improving feeding efficiency.

[0102] Next, the steps of the method for using the feeding system proposed in this application are explained with a specific embodiment. In one embodiment of this application, please refer to Figure 3The method of use is applied to the above-mentioned feeding system, and the method of use comprises the following steps:

[0103] Step S110 , when grabbing the battery cells 620 in the material packages on the battery grabbing area 200 , at least one material package is contained on the loading buffer device 120 , for example, one or more than two material packages are contained on the loading buffer device 120 .

[0104] The method for using the above-mentioned feeding system may further include the following steps:

[0105] When the feeding door 510 is closed, the loading buffer device 120 receives the material packages from the loading and feeding device 110. This step may be included in the above step S110, but it may not be included in the above step S110, and this embodiment does not limit this.

[0106] When the method for using the feeding system in this embodiment is used, by accommodating at least one material package on the feeding buffer device 120, the need for the gripping device 300 to stop and wait for material packages is reduced, which is beneficial to improving the feeding efficiency.

[0107] In addition, when the feeding system in this embodiment is used, when the feed door 510 is closed, the feeding buffer device 120 accommodates the material packaging from the feeding device 110, so that the feeding device 110 can prepare for the next material packaging more quickly, further improving the feeding efficiency.

[0108] Wherein, in some embodiments, reference Figure 3 , the method of use may further include the following steps:

[0109] Step S120, when grabbing the battery cell 620 in the material package on the battery grabbing area 200, the loading and feeding device 110 receives the material package from the conveying device. It can be understood that the action of grabbing the battery cell 620 in the material package on the battery grabbing area 200 and the action of the loading and feeding device 110 receiving the material package from the conveying device can be performed independently.

[0110] The method of using the feeding system in this embodiment is conducive to improving the degree of parallelization of the processes of the feeding device 110 and the gripping device 300, and is conducive to further improving the feeding efficiency.

[0111] In some embodiments, the first opening and closing detection device is used to send a door opening signal to the loading buffer device 120 when the feeding door 510 is opened, and the loading buffer device 120 is used to move the material package toward the battery grabbing area 200 according to the door opening signal.

[0112] In this embodiment, the opening state of the feed door 510 can be set to the state where the battery cells 620 in the corresponding battery grabbing area 200 have been grabbed; it can be understood that when the feed door 510 is opened to accept a new material package, the battery cells 620 in the corresponding material package have been grabbed. In this technical solution, the loading buffer device 120 is used to move the material package toward the battery grabbing area 200 according to the door opening signal, which improves the efficiency of the material package moving from the loading buffer device 120 to the battery grabbing area 200, and further improves the loading efficiency.

[0113] Correspondingly, based on the above structure of the feeding system, the method for using the above feeding system may further include the following steps:

[0114] When the feeding door 510 is opened, the material packages on the loading buffer device 120 are moved toward the battery grabbing area 200 .

[0115] When the feeding system in this embodiment is used, when the feed door 510 is opened, the material package on the feeding buffer device 120 is moved toward the battery grabbing area 200, thereby improving the efficiency of the material package moving from the feeding buffer device 120 toward the battery grabbing area 200, and further improving the feeding efficiency.

[0116] In some embodiments, the feeding system also includes a material grabbing detection device, which is used to detect whether the battery cells 620 in the material packaging on the battery grabbing area 200 have been completely grabbed by the grabbing device 300, and the material grabbing detection device is electrically connected to the feeding buffer device 120; when the battery cells 620 in the material packaging on the battery grabbing area 200 have been completely grabbed by the grabbing device 300, the material grabbing detection device is used to send a material grabbing completion signal to the feeding buffer device 120; the feeding buffer device 120 is used to transport the material packaging to the battery grabbing area 200 according to the material grabbing completion signal.

[0117] The material grabbing detection device may be set as an existing image recognition device, and the material grabbing detection device may also be provided with an infrared sensor or a contact sensor, etc. In this embodiment, a corresponding material grabbing detection device may be provided for each battery cell 620 in the material package, and at this time, each battery cell 620 is grabbed or the last battery cell 620 is grabbed, indicating that the battery cell 620 is completely grabbed by the grabbing device 300; a material grabbing detection device may also be provided for the last battery cell 620 to be grabbed in the preset sequence, and at this time, the last battery cell 620 is grabbed, indicating that the battery cell 620 is completely grabbed by the grabbing device 300.

[0118] In this embodiment, the loading buffer device 120 is used to convey material packaging to the battery grabbing area 200 according to the material grabbing completion signal. The material grabbing completion signal can be used to confirm that the battery cells 620 in the battery grabbing area 200 have been completely grabbed, thereby reducing the risk of collision between the material packaging on the loading buffer device 120 and the material packaging in the battery grabbing area 200, and reducing the risk of shutdown due to collision between material packaging, which is conducive to further improving the overall loading efficiency.

[0119] Correspondingly, based on the above embodiment of the feeding system, the method for using the above feeding system may further include the following steps:

[0120] When the battery cells 620 in the material packages on the battery grabbing area 200 are completely grabbed by the grabbing device 300 , the loading buffer device 120 conveys the material packages to the battery grabbing area 200 .

[0121] When the feeding system in this embodiment is used, when the battery cells 620 in the material packaging on the battery grasping area 200 are grasped by the grasping device 300, the feeding buffer device 120 transports the material packaging to the battery grasping area 200, thereby reducing the risk of collision between the material packaging on the feeding buffer device 120 and the material packaging in the battery grasping area 200, reducing the risk of shutdown due to collision between material packaging, and helping to further improve the overall feeding efficiency.

[0122] In some embodiments, the loading feed device 110 can also be used to move the material package toward the loading buffer device 120 , and the loading feed device 110 is used to move the material package independently of the loading buffer device 120 .

[0123] The loading and feeding device 110 can be configured as a conveyor belt, a roller bed, etc., so as to move the material package toward the loading and feeding buffer device 120. The loading and feeding device 110 moves the material package independently of the loading and feeding buffer device 120, which can be understood as the driving systems of the loading and feeding device 110 and the loading and feeding buffer device 120 are independent of each other.

[0124] In this embodiment, the loading and feeding device 110 can move the material package toward the loading buffer device 120 independently of the loading buffer device 120. It can be understood that the loading and feeding device 110 can move the material package a certain distance along the above-mentioned preset conveying direction, thereby reducing the complexity of the structure required for the loading buffer device 120 to accommodate the material package from the loading and feeding device 110, which is beneficial to improving the use stability of the loading buffer device 120 and improving the loading efficiency of the loading system during long-term operation.

[0125] In some embodiments, reference Figure 1The loading system may further include a transfer device and a unloading device 400; the unloading device 400 is arranged downstream of the battery grabbing area 200 along the preset conveying direction; the transfer device is used to transfer the supporting member 610 after the corresponding battery cell 620 is grabbed to the unloading device 400, and the unloading device 400 is used to transport the supporting member 610 outward along the preset conveying direction.

[0126] The transfer device may be a mechanical arm, or a clamping claw and a corresponding guide rail structure that enable the support 610 to move in a three-dimensional space. The unloading device 400 may be a conveying structure such as a conveyor belt or a roller bed.

[0127] It can be understood that, in this embodiment, the preset conveying direction is formed by the conveying direction of the loading and feeding device 110 (if the loading and feeding device 110 is capable of conveying), the loading buffer device 120 and the conveying direction of the unloading device 400.

[0128] In this embodiment, the transfer device and the unloading device 400 can transport the supporting member 610 outward, reducing the spatial interference of the supporting member 610 with the battery cells 620 to be grasped, which is beneficial to further improve the loading efficiency.

[0129] Correspondingly, the method for using the above-mentioned feeding system may further include the following steps:

[0130] When the battery cells 620 on the supporting members 610 on the battery grasping area 200 are completely grasped by the grasping device 300, the unloading device 400 conveys the corresponding supporting members 610 outward along the preset conveying direction.

[0131] When the method for using the feeding system in this embodiment is used, at least one material package can be accommodated on the feeding buffer device 120, thereby reducing the need for the gripping device 300 to stop and wait for the material package, which is conducive to improving the feeding efficiency. In addition, the method for using the feeding system can transport the support member 610 outward, reducing the spatial interference of the support member 610 with the battery cell 620 to be grasped, which is conducive to further improving the feeding efficiency.

[0132] In some embodiments, reference Figure 1 The unloading device 400 includes an unloading buffer device 410 ; along the preset conveying direction, the unloading buffer device 410 is arranged downstream of the battery grabbing area 200 , and the transfer device is used to transfer the supporting member 610 after the corresponding battery cell 620 is grabbed to the unloading buffer device 410 .

[0133] The unloading buffer device 410 can be configured as a conveying structure such as a conveyor belt, a roller bed, etc. It can be understood that in this embodiment, the preset conveying direction is formed by the conveying direction of the loading and feeding device 110 (if the loading and feeding device 110 is capable of conveying), the loading buffer device 120 and the unloading buffer device 410.

[0134] In this embodiment, the material unloading buffer device 410 can accommodate the material supporting member 610, reducing the number of conveying times along the preset conveying direction, which is beneficial to reducing the energy consumption of the loading system.

[0135] In some embodiments, reference Figure 1 The unloading device 400 also includes a unloading and discharging device 420; along the preset conveying direction, the unloading and discharging device 420 is arranged downstream of the unloading buffer device 410; the unloading buffer device 410 is used to transfer the supporting member 610 to the unloading and discharging device 420, and the unloading and discharging device 420 is used to convey the supporting member 610 outward along the preset conveying direction.

[0136] The material discharging device 420 can be configured as a conveying structure such as a conveyor belt or a roller bed. Figure 1 The preset conveying direction is formed by the conveying direction of the loading and feeding device 110 (if the loading and feeding device 110 is capable of conveying), the loading buffer device 120, the conveying direction of the unloading buffer device 410 and the conveying direction of the unloading and discharging device 420.

[0137] In this embodiment, the unloading and discharging device 420 can reduce the travel requirement of the unloading buffer device 410 along the preset conveying direction, which is beneficial to improving the structural stability of the unloading buffer device 410 and improving the loading efficiency of the loading system during long-term operation.

[0139] In this embodiment, the overall layout of the feeding system is relatively compact, which is conducive to reducing the overall footprint of the feeding system.

[0140] In some embodiments, reference Figure 1The loading system also includes a fence 530, which forms an enclosed space and has a first opening 531 and a second opening 532; the gripping device 300, the loading buffer device 120, the battery gripping area 200 and the unloading buffer device 410 are respectively arranged in the enclosed space, the input end of the loading buffer device 120 is connected to the first opening 531, and the output of the unloading buffer device 410 is connected to the second opening 532.

[0141] The fence 530 may be configured as an integral wall-like structure formed by panels, railings, and the like.

[0142] In this embodiment, the fence 530 can improve the safety of the feeding system, help reduce unexpected failures that may be caused by external moving objects, and help improve the feeding efficiency of the feeding system.

[0143] In some embodiments, reference Figure 1 The upper material feeding device 110 and the lower material discharging device 420 are respectively arranged outside the enclosed space, and the upper material feeding device 110 and the lower material discharging device 420 are arranged side by side and have opposite conveying directions; the output end of the upper material feeding device 110 is connected to the first opening 531, and the input end of the lower material discharging device 420 is connected to the second opening 532; the fence 530 includes a shielding section 534 arranged on the side of the upper material feeding device 110 facing away from the lower material discharging device 420, a first partition fence 541 is arranged between the upper material feeding device 110 and the lower material discharging device 420, and a second partition fence 542 is arranged on the side of the lower material discharging device 420 facing away from the upper material feeding device 110.

[0144] In this embodiment, the shielding section 534 is arranged on the side of the loading feeding device 110 facing away from the lowering and discharging device 420 (for example, the shielding section 534 is arranged on the left side of the loading feeding device 110), the first partition fence 541 is arranged between the loading feeding device 110 and the lowering and discharging device 420, and the second partition fence 542 is arranged on the side of the lowering and discharging device 420 facing away from the loading feeding device 110 (for example, the second partition fence 542 is arranged on the right side of the lowering and discharging device 420), which are respectively beneficial to further reduce unexpected failures that may be caused by external moving bodies and to further improve the loading efficiency of the loading system.

[0145] In some embodiments, the feeding system also includes a discharge gate 520 that can be opened and closed; along the preset conveying direction, the feed gate 510 is arranged upstream of the loading and feeding device 110, and the discharge gate 520 is arranged downstream of the unloading and discharging device 420; the two sides of the feed gate 510 are respectively connected to the shielding section 534 and the first partition fence 541, and the two sides of the discharge gate 520 are respectively connected to the first partition fence 541 and the second partition fence 542.

[0146] The discharge door 520 may be a rolling door or the like. Figure 1The shielding section 534 , the feed door 510 and the first partition fence 541 enclose the loading and unloading device 110 , and the first partition fence 541 , the discharge door 520 and the second partition fence 542 enclose the unloading and unloading device 420 .

[0147] In this embodiment, the openable and closable feed door 510 and the openable and closable discharge door 520 are respectively helpful in further reducing unexpected failures that may be caused by external moving objects, and are helpful in further improving the feeding efficiency of the feeding system.

[0148] In some embodiments, reference Figure 1 A first sensor 551 is provided at the first opening 531, and the first sensor 551 is at least used to detect a moving body between a projection of the material package at the first opening 531 along a preset conveying direction and an inner wall of the first opening 531; when the above-mentioned first opening and closing detection device detects that the feed door 510 is opened, the feeding system obtains a detection signal of the first sensor 551; when the first opening and closing detection device detects that the feed door 510 is closed, the feeding system shields the detection signal of the first sensor 551.

[0149] Among them, the first sensor 551 can be set as a first grating, and the first grating can detect a moving body along the width direction of the first opening 531, wherein the moving body can be a person or a vehicle, etc.; it can be understood that at this time, the first grating not only detects the moving body between the projection of the material package at the first opening 531 along the preset conveying direction and the inner wall of the first opening 531, but also detects the moving body in the projection space of the material package at the first opening 531 along the preset conveying direction. Correspondingly, the feeding system can be set to not output an abnormal detection signal when the material package passes through the first grating, but output an abnormal detection signal when the material package passes outside the first grating and the moving body is detected. Of course, the first grating can also detect the moving body along the up and down direction and between the projection of the material package at the first opening 531 along the preset conveying direction and the inner wall of the first opening 531, so as to avoid detecting the material package and avoid outputting an abnormal detection signal.

[0150] In addition, the first sensor 551 may also be configured as a photoelectric sensor or the like.

[0151] In this embodiment, the feeding system can obtain the detection signal of the first sensor 551 when the feeding door 510 is opened, which is conducive to improving the success rate of identifying the entry of an external moving body when the feeding door 510 is opened. The feeding system can also shield the detection signal of the first sensor 551 when the feeding door 510 is closed, reducing the risk of misjudgment caused by abnormal detection signals of the first sensor 551. In addition, the feeding system can also improve the efficiency of obtaining or shielding the detection signal of the first sensor 551 through the first opening and closing detection device.

[0152] Correspondingly, the method for using the above-mentioned feeding system may further include the following steps:

[0153] When the feed door 510 is opened, a detection signal of the first sensor 551 is obtained;

[0154] When the feed door 510 is closed, the detection signal of the first sensor 551 is shielded.

[0155] Among them, shielding the detection signal of the first sensor 551 can be understood as the feeding system no longer judging whether there is a moving object based on the detection signal of the first sensor 551 .

[0156] The method of using the feeding system in this embodiment is helpful in improving the success rate of identifying the entry of an external moving object when the feeding door 510 is opened, and improving the efficiency of acquiring or shielding the detection signal of the first sensor 551.

[0157] In some embodiments, reference Figure 1 A second sensor 552 is provided at the second opening 532, and the second sensor 552 is at least used to detect a moving body between the projection of the supporting member 610 at the second opening 532 along a preset conveying direction and the inner wall of the second opening 532; the feeding system also includes a second opening and closing detection device, and the second opening and closing detection device is used to detect the opening and closing state of the discharge door 520; when the second opening and closing detection device detects that the discharge door 520 is open, the feeding system obtains a detection signal of the second sensor 552; when the second opening and closing detection device detects that the discharge door 520 is closed, the feeding system shields the detection signal of the second sensor 552.

[0158] Among them, the second sensor 552 can be set as a second grating, and the second grating can detect a moving body along the width direction of the second opening 532, wherein the moving body can be a person or a vehicle, etc.; it can be understood that at this time, the second grating not only detects the moving body between the projection of the material package at the second opening 532 along the preset conveying direction and the inner wall of the second opening 532, but also detects the moving body in the projection space of the material package at the second opening 532 along the preset conveying direction. Correspondingly, the feeding system can be set to not output an abnormal detection signal when the material package passes through the second grating, but output an abnormal detection signal when the material package passes outside the second grating and the moving body is detected. Of course, the second grating can also detect the moving body along the up and down direction and between the projection of the material package at the second opening 532 along the preset conveying direction and the inner wall of the second opening 532, so as to avoid detecting the material package and avoid outputting an abnormal detection signal.

[0159] In addition, the second sensor 552 may also be configured as a photoelectric sensor or the like.

[0160] In this embodiment, the feeding system can obtain the detection signal of the second sensor 552 when the discharge door 520 is opened, which is conducive to improving the success rate of identifying the entry of an external moving object when the discharge door 520 is opened. The feeding system can also shield the detection signal of the second sensor 552 when the discharge door 520 is closed, reducing the risk of misjudgment caused by abnormal detection signals of the second sensor 552. In addition, the feeding system can also improve the efficiency of obtaining or shielding the detection signal of the second sensor 552 through the second opening and closing detection device.

[0161] Correspondingly, the method for using the above-mentioned feeding system may further include the following steps:

[0162] When the discharge door 520 is opened, a detection signal of the second sensor 552 is obtained;

[0163] When the discharge door 520 is closed, the detection signal of the second sensor 552 is shielded.

[0164] Among them, shielding the detection signal of the second sensor 552 can be understood as the feeding system no longer judging whether there is a moving object based on the detection signal of the second sensor 552.

[0165] When used, the method of using the loading system in this embodiment is beneficial to improving the success rate of identifying the entry of an external moving object when the discharge door 520 is opened, and improving the efficiency of obtaining or shielding the detection signal of the second sensor 552.

[0167] Among them, the height position sensor can be set as a photoelectric sensor, an infrared sensor, etc.

[0168] In this embodiment, the height position detection device can reduce the operator's operation and improve the efficiency of the outward transportation of the material supporting member 610 when the material supporting member 610 reaches a preset height, which is beneficial to improving the overall loading efficiency.

[0170] In this embodiment, the loading and feeding device 110 and the battery grabbing area 200 are respectively arranged on opposite sides of the loading and feeding buffer device 120, which is conducive to increasing the distance between the loading and feeding device 110 and the battery grabbing area 200 through the loading and feeding buffer device 120, which is conducive to reducing the risk of the grabbing device 300 interfering with the operator or object at the loading device, and is conducive to improving the safety of the loading system. While the third opening 533 allows the battery cell 620 grabbed by the grabbing device 300 to be output to the outside, the fence 530 can maintain a high degree of enclosure, which is conducive to improving the safety of the loading system, reducing unexpected failures that may be caused by external moving objects, and improving the loading efficiency of the loading system.

[0171] Correspondingly, the method for using the above-mentioned feeding system may further include the following steps:

[0172] When the battery cells 620 on the supporting members 610 on the battery grabbing area 200 are completely grabbed by the grabbing device 300, the transfer device stacks the corresponding supporting members 610 on the unloading buffer device 410;

[0173] When the supporting member 610 on the material unloading buffer device 410 reaches a preset height, the supporting member 610 is transported outward.
