[0086] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. It should be understood that the specific embodiments described herein are only used to explain the relevant applications and are not intended to limit the relevant applications. It should also be noted that for ease of description, only the portions relevant to the relevant applications are shown in the drawings.

[0087] New energy batteries are increasingly being used in everyday life and industry. For example, battery-powered new energy vehicles are already widely used, and batteries are also increasingly being applied to energy storage. New energy batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power stations, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in aerospace and other fields. As the application areas of power batteries continue to expand, their market demand is also growing.

[0088] In the lithium battery production process, the presence of organic matter such as water molecules can be extremely harmful, causing overheating and explosion. Therefore, the battery must be vacuum-baked before filling and sealing to fully dry the interior. With the rapid development of the new energy vehicle market, the demand for lithium batteries has doubled, placing high demands on battery production lines for both high cycle times and high safety.

[0089] Among the current related baking methods, on the one hand, they cannot meet the high-speed production requirements, and on the other hand, they cannot meet the production processes such as the discharge of defective (NG) batteries, and the loading and re-injection of batteries for testing.

[0090] In order to solve the problems existing in the current battery baking method, the embodiments of the present disclosure provide a battery baking system and a battery baking method, which can support the discharge of defective batteries, as well as the loading and re-loading of test batteries, and can simultaneously execute the loading and unloading of batteries, and the entry and exit of batteries into the furnace; effectively improve the intelligence and automation level of the battery baking system, can meet the high-beat production requirements, and thus improve production efficiency.

[0091] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure.

For technical details not disclosed in the method embodiment, please refer to the description of the system embodiment of the present disclosure for understanding.

[0093] An embodiment of the present disclosure provides a battery baking system, as shown in Figures 1, 2, 3, and 4. The battery baking system 0 may include a control device 1, a first servo gripper 2, a loading belt 3, a first pairing platform 4, a baking oven 5, a third pairing platform 6, a test battery loading belt 7, and a second unloading belt 8; wherein:

[0094] The control device 1 is used to control the first servo gripper 2 to move the first battery to be baked to the first pairing platform 4 when there are no defective batteries among the first number of first batteries to be baked on the loading pull belt 3 and they are not the first group of batteries corresponding to entering the first baking oven; and to control the first servo gripper 2 to move the defective batteries to the second unloading pull belt 8 and unload the defective batteries through the second unloading pull belt 8 when there are defective batteries among the first batteries to be baked and they are not the first group of batteries corresponding to entering the first baking oven; and to control the first servo gripper 2 to move a test battery from the test battery loading pull belt 7 to the third pairing platform 6 when the first battery to be baked is the first group of batteries corresponding to entering the first baking oven, and to control the first servo gripper 2 to move the good batteries among the first batteries to be baked to the third pairing platform 6.

[0095] It should be noted that there can be multiple baking ovens 5; the first baking oven is any idle baking oven among the multiple baking ovens 5.

[0096] In the embodiment of the present disclosure, the loading tape 3 can be used to provide the first battery to be baked; the first battery to be baked represents the battery to be baked that is grabbed from the loading tape.

[0097] In the embodiment of the present disclosure, the battery baking system 0 may further include a first robot 9 .

[0098] It should be noted that in the embodiments of the present disclosure, the specific value of the first quantity is not limited in the present disclosure. For example, the first quantity can be 4. When the four first batteries to be baked on the loading pull belt 3 are all good batteries and are not the first group of batteries corresponding to entering the first baking furnace, the first servo gripper 2 can transport the four first batteries to be baked on the loading pull belt 3 to the first pairing platform 4.

[0099] It should be noted that in the embodiment of the present disclosure, whether the battery is a bad (NG) battery can be determined by scanning the barcode of the battery to be baked, that is, by reading the barcode of the battery to be baked, whether the battery to be baked is a bad battery can be determined.

[0100] In an embodiment of the present disclosure, the servo gripper in the battery baking system 0 may include a first servo gripper 2 and a second servo gripper 20; the servo gripper can be arranged on a conveying shaft, for example, as shown in Figure 2, the first servo gripper 2 is arranged on a first conveying shaft 2111, and the second servo gripper 20 is arranged on a second conveying shaft 2112; wherein, the first conveying shaft 2111 and the second conveying shaft 2112 can be used to carry and transport batteries.

[0101] It should be noted that, in the embodiment of the present disclosure, the first servo gripper 2 and the second servo gripper 20 can grasp a first number of batteries each time.

[0102] Exemplarily, as shown in FIG3 , the battery baking system 0 may further include a barcode scanning device 14 , which may be a barcode scanning gun; the four first batteries to be baked on the loading belt 3 may pass through the barcode scanning device 14 , and the barcode scanning device 14 may send the obtained barcodes of the four first batteries to be baked to the control device 1 , so that the control device 1 may determine whether defective batteries are included therein based on the barcodes of the four first batteries to be baked.

[0103] Exemplarily, as shown in Figure 3, the battery baking system 0 may also include a first blocking cylinder 15, which can be used to block the batteries to be baked transmitted on the loading pull belt 3, so that after the previous group of the first number of batteries to be baked on the loading pull belt 3 are transferred out, the next group of the first number of batteries to be baked can be released; for example, after the first servo gripper 2 transports the 4 first batteries to be baked on the loading pull belt 3 to the first pairing platform, the control device 1 controls the first blocking cylinder 15 to release the currently blocked last group of 4 first batteries to be baked.

[0104] It should be noted that, in the embodiment of the present disclosure, the first pairing platform 4 can be used to provide a second quantity of good quality batteries to be baked.

[0105] It should be noted that, in the embodiment of the present disclosure, the control device 1 can determine the first idle baking oven among the multiple baking ovens 5, thereby determining the mapping relationship between the battery to be baked currently in transfer and the first baking oven, and the mapping relationship represents the battery to be baked entering the first baking oven for baking; for example, the control device 1 determines that the first idle baking oven among the multiple baking ovens 5 that is not baking is A, and determines that the battery to be baked currently in transfer enters A for baking, then it can be judged whether the battery to be baked currently in transfer is the first group of 4 batteries to be subsequently entered into A for baking, so as to determine whether the first sub-event is triggered.

[0106] In an embodiment of the present disclosure, as shown in Figure 2, the baking oven 5 can be arranged in a baking cavity 51. For example, every two baking ovens can be placed in a baking cavity 51, and the baking ovens 5 in different baking cavities 51 can be moved; the baking cavity 51 can include a sensor, and the sensor can be used to detect whether the baking oven is performing a baking operation, so that the control device 1 can determine the first baking oven by receiving information sent by the sensor.

[0107] The first robot 9 can be used to transfer a second number of third batteries to be baked from the first pairing platform 4 to the loading position 10 when the number of batteries to be baked on the first pairing platform 4 reaches a second number; wherein the first number is smaller than the second number.

[0108] It should be noted that, in the embodiments of the present disclosure, the specific value of the second number is not limited in the present disclosure, but the first number is smaller than the second number, and the second number can be an integer multiple of the first number; for example, the second number can be 12.

[0109] For example, the first quantity is 4 and the second quantity is 12. The control device 1 can control the first servo gripper 2 to grab the first batteries to be baked from the loading belt 3 times, with the number of batteries grabbed each time being 4, and place them on the first pairing platform, so that the number of third batteries to be baked on the first pairing platform is 12. At this time, the control device 1 can determine that the number of batteries to be baked on the first pairing platform has reached the second quantity.

[0110] It can be understood that, in the embodiment of the present disclosure, the third battery to be baked represents the battery to be baked on the first pairing platform.

[0111] It should be noted that, in the embodiment of the present disclosure, the battery baking system 0 may include two robots, which may be six-axis industrial robots equipped with handling grippers; the two robots may include a first robot 9 and a second robot 21; wherein the first robot 9 is used to transfer the batteries to be baked to the upper material position, and the second robot 21 is used to transfer the baked batteries from the lower material position.

[0112] It should be noted that, in the embodiment of the present disclosure, the first robot 9 and the second robot 21 can grab at most the second number of batteries each time.

[0113] For example, when the control device 1 determines that the first guide trolley 12 is currently being used to transfer the batteries to be baked to the first baking oven, that is, the first guide trolley 12 is not idle, and the second guide trolley 13 is idle, the control device 1 can determine to instruct the second guide trolley 13 to transfer the baked batteries in the second baking oven to the unloading position.

[0114] It should be noted that in an embodiment of the present disclosure, as shown in Figure 8, the battery baking system 0 may further include a loading position 10, and the number of loading positions 10 may be 2. For example, as shown in Figure 2, the loading position 10 may include a first loading position 101 and a second loading position 102; when the control device 1 controls the first robot 9 to transfer the second quantity of third batteries to be baked from the first pairing platform 4 to the loading position 10, it can choose to transfer the second quantity of third batteries to be baked to any one of the first loading position 101 and the second loading position 102.

[0115] It should be noted that, in the embodiment of the present disclosure, a third number of batteries can be placed in the loading position at most, and the third number is greater than the second number. For example, the third number can be 420.

[0116] Exemplarily, when both the first loading position 101 and the second loading position 102 are empty, the control device 1 selects one of the loading positions, such as the first loading position 101, so that the first robot 9 can be controlled to transfer 12 (second quantity) of the third batteries to be baked from the first pairing platform 4 to the first loading position 101 each time. When the number of batteries to be baked in the first loading position 101 reaches 420, the control device 1 can then control the first robot 9 to transfer the batteries to be baked to the second loading position 102.

[0117] In an embodiment of the present disclosure, the battery baking system 0 may further include a first cache position 11, a first guide trolley 12 and a second guide trolley 13; as shown in Figure 2, the battery baking system 0 may further include a transfer mechanism motion shaft 223, and the first guide trolley 12 and the second guide trolley 13 may be arranged on the transfer mechanism motion shaft 223.

[0118] It should be noted that, in the embodiment of the present disclosure, both the first guide trolley 12 and the second guide trolley 13 can be rail guided vehicles (RGV) composed of a linear motor and a servo motor.

[0119] The control device 1 can be used to control the loading position 10 to transfer the third quantity of second batteries to be baked to the first cache position 11 when the number of batteries to be baked on the loading position 10 reaches the third quantity; and control any idle guide trolley among the first guide trolley and the second guide trolley to transfer the second batteries to be baked in the first cache position 11 to the first baking furnace; and control the first baking furnace to bake the second batteries to be baked; wherein the third quantity is greater than the second quantity, and the third quantity can be an integer multiple of the second quantity.

[0120] It should be noted that, in an embodiment of the present disclosure, as shown in Figure 8, the battery baking system 0 may further include a first cache position 11; as shown in Figure 2, the first cache position 11 may include a third cache position 111 and a fourth cache position 112; wherein, the third cache position 111 may correspond to the first loading position 101, and the fourth cache position 112 may correspond to the second loading position 102; accordingly, when the control device controls the loading position to transfer the third quantity of second batteries to be baked to the first cache position, it may control the first loading position 101 to push the third quantity of batteries to be baked into the third cache position 111 when the number of batteries to be baked in the first loading position 101 reaches the third quantity, and control the second loading position 102 to push the third quantity of batteries to be baked into the fourth cache position 112 when the number of batteries to be baked in the second loading position 102 reaches the third quantity.

[0121] It should be noted that, in the embodiment of the present disclosure, the first cache position 11 can hold a third number of batteries to be baked; for example, the first cache position 11 is divided into 7 layers, each layer can hold 5 groups of batteries, and each group can hold 12 (the second number) batteries, so that the first cache position 11 can hold 7×5×12, a total of 420 (the third number) batteries to be baked.

[0122] It can be understood that the second battery to be baked refers to the battery to be baked located in the loading position.

[0123] In an embodiment of the present disclosure, a third number of batteries can also be placed in the baking oven 5; after receiving all the second batteries to be baked from the first cache position, the first baking oven can bake and dry the second batteries to be baked to remove organic matter such as water molecules in the second batteries to be baked.

[0124] In an embodiment of the present disclosure, as shown in FIG2 , the battery baking system 0 may further include a first rotating mechanism 29 and a second rotating mechanism 30 ; wherein the first rotating mechanism 29 may be used to rotate the third cache position 111 , and the second rotating mechanism 30 may be used to rotate the fourth cache position 112 .

[0125] Exemplarily, when the control device 1 controls any idle guide trolley among the first guide trolley and the second guide trolley to transfer the second battery to be baked in the first cache position to the first baking oven, for example, when transferring the battery to be baked in the third cache position 111 to the first baking oven, it can control the first rotating mechanism 29 to rotate the third cache position 111 90 degrees so that the angle of the third cache position 111 can match the angle of the first baking oven, and then control any idle guide trolley among the first guide trolley and the second guide trolley to transfer the battery to be baked in the third cache position 111 to the first baking oven.

[0126] It can be seen that even if one of the first guide trolley or the second guide trolley is performing the unloading operation, the remaining idle guide trolley can perform the entering operation, thereby improving the efficiency of the battery entering the baking oven for baking.

[0127] In the embodiment of the present disclosure, the battery baking system 0 may further include a second buffer position 16 and a material unloading position 17 .

[0128] The control device 1 can also be used to control any idle guide trolley among the first guide trolley and the second guide trolley to transfer a third number of first baked batteries in the second baking oven to the second cache position 16 when it is determined that there is a second baking oven among multiple baking ovens; and to control the second cache position 16 to transfer the first baked batteries to the unloading position 17; wherein the second baking oven represents a baking oven that has completed baking.

[0129] It should be noted that in an embodiment of the present disclosure, as shown in Figure 8, the battery baking system 0 may further include a discharge position 17; as shown in Figure 2, the discharge position 17 may include a first discharge position 171 and a second discharge position 172; when the control device 1 controls the second cache position to transfer the first baked battery to the discharge position, it can choose to transfer the first baked battery to any one of the first discharge position 171 and the second discharge position 172.

[0130] It should be noted that, in an embodiment of the present disclosure, as shown in Figure 8, the battery baking system 0 may further include a second cache position 16; as shown in Figure 2, the second cache position 16 may include a fifth cache position 161 and a sixth cache position 162; wherein, the fifth cache position 161 may correspond to the first unloading position 171, and the sixth cache position 162 may correspond to the second unloading position 172; accordingly, when the control device controls the second cache position to transfer the first baked battery to the unloading position, the first baked battery of the fifth cache position 161 may be transferred to the first unloading position 171, and the first baked battery of the sixth cache position 162 may be transferred to the second unloading position 172.

[0131] In an embodiment of the present disclosure, the battery baking system 0 may further include a third rotating mechanism 18 and a fourth rotating mechanism 19; wherein the third rotating mechanism 18 can be used to rotate the fifth cache position 161, and the fourth rotating mechanism 19 can be used to rotate the sixth cache position 162; for example, when the control device controls any idle guide trolley among the first guide trolley and the second guide trolley to transfer the third quantity of first baked batteries in the second baking oven to the second cache position 16, the third rotating mechanism 18 can be controlled to rotate the fifth cache position 161, and then transfer the third quantity of first baked batteries in the second baking oven to the fifth cache position 161; the fourth rotating mechanism 19 can also be controlled to rotate the sixth cache position 162, and then transfer the third quantity of first baked batteries in the second baking oven to the sixth cache position 162.

[0132] It should be noted that, in the embodiment of the present disclosure, the unloading position 17 can also hold a maximum of a third number of batteries.

[0133] Exemplarily, when the control device controls the second cache position to transfer the first baked battery to the unloading position, when both the first unloading position 171 and the second unloading position 172 are empty, the control device 1 can select any one of the unloading positions, such as the first unloading position 171, so that the first baked battery in the second cache position can be transferred to the first unloading position 171; when the control device determines that only the second unloading position 172 is empty among the first unloading position 171 and the second unloading position 172, the first baked battery in the second cache position can be transferred to the second unloading position 172.

[0134] It should be noted that the second cache position 16 may include a fifth cache position 161 and a sixth cache position 162; wherein, the fifth cache position 161 may correspond to the first unloading position 171, and the sixth cache position 162 may correspond to the second unloading position 172; accordingly, when the control device controls the second cache position 16 to transfer the first baked battery to the unloading position 17, it may transfer the first baked battery in the fifth cache position 161 to the first unloading position 171, and may also transfer the first baked battery in the sixth cache position 162 to the second unloading position 172.

[0136] It can be seen that even if one of the first guide trolley or the second guide trolley is performing the furnace entry operation, the remaining idle guide trolley can perform the furnace exit operation, thereby improving the efficiency of removing the baked batteries.

[0137] In the embodiment of the present disclosure, the battery baking system 0 may further include a second servo gripper 20 , a second robot 21 , a second pairing platform 22 , and a first blanking belt 23 .

[0138] The control device 1 can also be used to control the second robot 21 to transfer a second quantity of third baked batteries from the second baked batteries on the unloading position 17 to the second pairing platform 22 when baked batteries exist on the unloading position 17 .

[0139] It should be noted that, in the embodiment of the present disclosure, the second pairing platform 22 is used to place the second quantity of third baked batteries transferred from the unloading position.

[0140] It should be noted that, in the embodiment of the present disclosure, the first blanking pull belt 23 is used to blank the baked good batteries.

[0141] It is understood that, in the embodiment of the present disclosure, the third post-baking battery refers to a battery to be baked that is grabbed from the second battery to be baked on the unloading position.

[0142] The control device 1 can also be used to control the second servo gripper 20 to grab a first quantity of fourth baked batteries from the second pairing platform 22 when the number of baked batteries on the second pairing platform 22 reaches a second quantity; and to control the second servo gripper 20 to move the fourth baked batteries to the first unloading belt 23 for unloading when all the fourth baked batteries are good and do not include baked test batteries.

[0143] In an embodiment of the present disclosure, a quality analysis may be performed on the baked battery to determine whether the baked battery is a good quality battery.

[0144] It should be noted that in the embodiment of the present disclosure, the third number of batteries to be baked each time the baking furnace bakes includes a test battery, and correspondingly, the third number of baked batteries obtained from the baking furnace after baking must include a baked test battery; except for the baked test batteries, the remaining good baked batteries can be unloaded through the first unloading pull belt 23.

[0145] Exemplarily, as shown in FIG4 , the battery baking system 0 may further include a second blocking cylinder 24 , which may be used to block the baked batteries on the first unloading belt 23 so that the baked batteries on the first unloading belt 23 do not collide and are unloaded in an orderly manner.

[0146] In the embodiment of the present disclosure, the control device 1 can also be used to control the first servo gripper 2 to carry the remaining batteries to be baked except for defective batteries in the first batteries to be baked to the third pairing platform 6 .

[0147] For example, A, B, C, and D are not the first group of batteries corresponding to the first baking furnace, and C is a defective battery. The control device 1 can control the first servo gripper 2 to move C to the second unloading belt 8 for unloading; and control the first servo gripper 2 to move A, B, and D to the third pairing platform 6.

[0148] The control device 1 can also be used to control the first servo gripper 2 to transport a first quantity of fourth batteries to be baked from the third pairing platform 6 to the first pairing platform 4 when the number of batteries on the third pairing platform 6 reaches a first quantity, so as to transfer the fourth batteries to be baked to the loading position 10 through the first pairing platform 4.

[0149] In some embodiments of the present disclosure, the fourth battery to be baked may include a test battery.

[0151] It can be understood that since the third pairing platform 6 can be used to place the good batteries among the first number of batteries to be baked grabbed each time, when the first number of batteries to be baked on the third pairing platform 6 is reached, the fourth batteries to be baked of the first number on the third pairing platform 6 can be transferred to the first pairing platform 4, so that the number of batteries to be baked on the first pairing platform 4 gradually reaches the second number, and the batteries to be baked are transferred to the loading position through the first pairing platform 4, and then transferred to the first cache position based on the loading position, and finally transferred to the first baking furnace to complete baking.

[0152] It can be understood that the fourth battery to be baked refers to the battery to be baked grabbed from the third pairing platform.

[0153] In the embodiment of the present disclosure, the battery baking system 0 may further include a fourth pairing platform 25 and a third blanking belt 27 .

[0159] The control device 1 can also be used to control the second servo gripper 20 to carry the first number of fifth baked batteries from the fourth pairing platform 25 to the first unloading belt 23 for unloading when the fifth baked batteries on the fourth pairing platform 25 reach the first number.

[0160] In the embodiment of the present disclosure, the battery baking system 0 may further include a test battery re-dropping pull belt 26 .

[0161] It should be noted that in the embodiment of the present disclosure, the water content of the test battery after baking can be tested by a water content tester after unloading. When the water content of the test battery after baking is less than the preset water content threshold, the test is deemed to be successful; when the water content of the test battery after baking is greater than or equal to the preset water content threshold, the test is deemed to have failed; wherein, the preset water content threshold is not limited in this disclosure.
