Description

Technical Field

[0001] The present application relates to the field of battery production equipment, and in particular to a battery powder conveying system and a battery production line. Background Art

[0002] At present, the layout of lithium battery production plant is a two-story structure: the first floor is the mixing workshop, and the second floor is the powder workshop. The powder material conveying process includes conveying the main materials and auxiliary materials in the powder workshop to the mixer in the mixing workshop.

[0003] The operating procedures for main material transportation are as follows: the main material unpacking station and the main material metering bin are located directly above the mixer and are generally configured in a "one-to-one" and "one-to-two" manner with the mixer. The powder material ton bag pallet is manually transferred to the bottom of the overhead crane by a forklift, and the employee connects the overhead crane to the ton bag and lifts the ton bag to the steel platform unpacking station on the upper part of the second-floor material distribution workshop to unpack the ton bag, and uses gravity feeding to feed the material in the ton bag to the main material metering bin for storage. After the central control system issues a demand for pulping and feeding the main material, the powder system sends a request signal to the mixer. After the employee confirms that the mixer status meets the requirements, he can click the allow button to reply to the allow signal, the valve of the feeding pipe opens, and the feeding screw under the main material metering bin starts to feed powder to the mixer. The synchronous metering scale starts weighing, and after reaching the preset slow weighing value, the screw slows down and weighs slowly until it reaches the set powder feeding weight, stops, and returns a completion signal.

[0004] The operating procedures for auxiliary material transportation are as follows: auxiliary materials generally have 1 to 3 categories according to the formula, and different first-level metering tanks are designed according to the types of auxiliary materials, and the first-level metering sending tank is designed according to the configuration of "one to many" mixers. The bagged powder is manually transferred to the suction room and the material is transported to the auxiliary material first-level metering tank by negative pressure feeding. After the central control system issues a demand for pulping auxiliary materials, the powder system sends a request signal to the mixer. After the employee confirms that the mixer status meets the requirements, he can click the allow button to reply to the allow signal. The valve of the material discharge pipe opens, and the feeding screw under the first-level metering bin of the auxiliary materials required by the formula starts to feed powder to the mixer. The synchronous metering scale starts weighing. After reaching the preset slow weighing value, the screw slows down and weighs slowly until it reaches the set powder weight and stops. After the metering of different types of auxiliary materials is completed, they are transported to the designated mixer by positive pressure sending from the sending tank.

[0005] The operations of unpacking and feeding powder and feeding into the mixer are both located in the same space. The partial leakage of dust during feeding can easily directly pollute the workshop environment. Since there are strict requirements on the inclination angle of the gravity feeding pipeline, according to the current plan, at least one main material metering bin is configured to be connected to two mixers at the same time. For lithium batteries with dual main material formulas, the powder workshop needs to densely arrange a large number of main material metering tanks and corresponding unpacking stations, which greatly increases the investment cost; the utilization rate of the unpacking station is low, and employees need to frequently transfer ton bags to unpacking stations in different locations, which is labor-intensive. The powder feeding time and rhythm of the materials are controlled by the employees. If the feeding is not timely, it will affect the production line capacity. There is a risk of leakage when the auxiliary materials are sent to the mixer using positive pressure conveying, and the energy consumption is high. Utility Model Content

[0039] Embodiment 1

[0040] See also Figure 1 and Figure 2 As shown, the battery powder conveying system provided in the present application includes a material preparation workshop 101, a material storage workshop 102 and a transport mechanism.

[0041] The material preparation workshop 101 and the material storage workshop 102 are isolated from each other. The material preparation workshop 101 is provided with an unpacking station 103 and an unpacking temporary storage bin 104 located below the unpacking station 103, which is the unpacking area. When the powder ton bag 106 loaded with the main material is transported to the unpacking station 103, the unpacking station 103 can centrally unpack the powder ton bag 106 so that the main material falls into the unpacking temporary storage bin 104 for storage, that is, the powder feeding process is located in the material preparation workshop 101, and the generated dust only spreads in the independent space of the material preparation workshop 101, and will not pollute most other areas of the workshop.

[0042] The material storage workshop 102 is provided with a main material metering bin 105, and a first connecting pipe is provided between the unpacking temporary storage bin 104 and the main material metering bin 105, and the main material in the unpacking temporary storage bin 104 can be sent to the main material metering bin 105 for storage through the first connecting pipe. The main material dropping time is 180s shorter than the sending time. The unpacking temporary storage bin 104 is designed below the unpacking station 103, so that the dropping process and the sending process can be separated, which can improve the feeding efficiency.

[0043] When the central control system of the powder material dispatches work in combination with the production status of the mixer 107 and the work order task, a specific production of the mixer 107 can be formulated. When the formulated mixer 107 reaches the feeding conditions, the central control system determines whether the storage status of the main material metering bin 105 of the storage workshop 102 meets the formula requirements. If it does, it sends a task to the carrier to dispatch the carrier to the main material metering bin 105. The main material metering bin 105 can accurately weigh the main material and transport the preset amount of main material to the carrier. The carrier transports the main material to the unloading station set in the storage workshop 102. The unloading station is connected to the mixer 107 so that the main material loaded by the carrier can enter the mixer 107, and the mixer 107 can perform the mixing program. The overall coordination and dispatching by the central control system and the coordinated transportation by the logistics system can reduce the delay of the production plan caused by human intervention and improve production efficiency.

[0044] That is to say, in the material storage workshop 102, the transport mechanism transports the main material to the mixer 107 according to the needs of the mixer 107. It is not necessary to set up a set of unpacking station 103 and metering bin above each mixer 107 or every two mixers 107, which can also greatly reduce the number of the above devices and reduce the occupation of the workshop space by the above devices. Taking the single-line setting of 10 mixers 107 as an example (including 6 cathodes and 4 anodes), the number of metering bins configured for the dual main material powder system is reduced from 10 sets to 4 sets, which greatly saves the occupation of workshop space.

[0045] More specifically, the first connecting pipeline includes a feeder 108, a first valve 109, a first pipeline 110 and a first vacuum feeder 111. The feeder 108 and the first vacuum feeder 111 are both connected to the first pipeline 110. The feeder 108 is arranged at the bottom outlet of the unpacking temporary storage bin 104. The powder material can be accurately weighed by cooperating with the feeder 108 and the weighing scale of the unpacking temporary storage bin 104. The first vacuum feeder 111 is arranged at the entrance of the main material metering bin 105 so that the material is sucked into the main material metering bin 105, so as not to block the first pipeline 110. The first valve 109 is installed on the first pipeline 110 to realize the connection or shutoff of the first pipeline 110.

[0046] It should be noted that the type of main ingredients can be one or more, which is specifically set according to the actual formula. Correspondingly, the number of unpacking stations 103 for processing the main ingredients, the number of unpacking temporary storage bins 104, the number of first connecting pipes and the number of main ingredient metering bins 105 are set according to the type of main ingredients. Figure 1 and Figure 2 The device structure corresponding to the two main materials is shown in FIG.

[0047] In the optional solution of this embodiment, the material preparation workshop 101 is further provided with an auxiliary material suction room 112, which is used to suck bagged auxiliary materials. The material storage workshop 102 is provided with an auxiliary material metering bin 113, which is used to store and accurately weigh auxiliary materials, and a second connecting pipe is provided between the auxiliary material suction room 112 and the auxiliary material metering bin 113; the auxiliary materials sucked by the auxiliary material suction room 112 can be transported to the auxiliary material metering bin 113 for storage through the second connecting pipe.

[0048] When the central control system of the powder material combines the production status of the mixer 107 and the work order task for dispatching work, the specific production of the mixer 107 can be formulated. When the formulated mixer 107 meets the feeding conditions, the central control system determines whether the storage status of the auxiliary material metering bin 113 in the storage workshop 102 meets the formula requirements. If so, the task is sent to the transport mechanism to dispatch the transport mechanism to the auxiliary material metering bin 113. The auxiliary material metering bin 113 can accurately weigh the main material and transport a preset amount of auxiliary material to the transport mechanism. The transport mechanism transports the auxiliary material to the unloading station set up in the storage workshop 102. The unloading station is connected to the mixer 107 so that the auxiliary material loaded by the transport mechanism can enter the mixer 107, and the mixer 107 can execute the mixing program.

[0049] More specifically, the second communication pipeline includes a second valve, a second pipeline 114 and a second vacuum feeder 115. The second pipeline 114 is connected to the outlet of the auxiliary material suction room 112, and the second vacuum feeder 115 is connected to the second pipeline 114. The second vacuum feeder 115 is arranged at the entrance of the auxiliary material metering bin 113 so that the material is sucked into the auxiliary material metering bin 113, so as not to block the second pipeline 114. The second valve is installed on the second pipeline 114 to realize the connection or shutoff of the second pipeline 114.

[0050] In the optional solution of this embodiment, Figure 1 As shown, the transport mechanism includes a transport vehicle 116, a batching vehicle 120 and a plurality of transfer tanks 117, and any transfer tank 117 can be detachably mounted on the transport vehicle 116 and the batching vehicle 120. Specifically, the transport vehicle 116 is an automatic guided vehicle, i.e., AGV; the batching vehicle 120 is a rail-guided vehicle, i.e., RGV; and the transfer tank 117 is an IBC tank.

[0051] The specific batching process is as follows: when the central control system sends a task to the AGV scheduling system, the AGV scheduling system can schedule the AGV to transfer the IBC tank to the batching area equipped with the main material metering bin 105 and the auxiliary material metering bin 113. The batching area is equipped with RGV, and the AGV can transfer the IBC tank to the RGV. A batching docking device 121 is provided below the main material metering bin 105 and the auxiliary material metering bin 113. The batching docking device 121 includes a feeding screw and an automatic docking interface. The RGV can move along a preset path to accurately transplant the IBC tank to the bottom of the main material metering bin 105 and the auxiliary material metering bin 113, so that the IBC tank can be connected to the automatic docking interface of any batching docking device 121. After the feeding screw is started, the material can be accurately weighed and fed according to the formula, and the main material and auxiliary material can be distributed to the IBC tank in proportion.

[0052] After the batching process is completed, the RGV can transfer the IBC tank to the AGV, and the AGV transfers the IBC tank to the unloading station. The unloading station is equipped with a unloading docking device 118 and a material dropping pipe 119. The unloading docking device 118 is connected to the mixer 107 through the material dropping pipe 119. When the AGV transports the IBC tank to the top of the unloading station, the unloading docking device 118 can automatically dock with the IBC tank and initiate a unloading request signal to the mixer 107. The unloading will be carried out after the employee confirms the status of the mixer 107 and replies to the permission signal. After the unloading is completed, the AGV scheduling system will determine whether the IBC tank will be transferred to the IBC tank temporary storage area or the batching area to continue batching according to whether there are tasks queued up later.

[0053] Embodiment 2

[0054] The battery powder conveying system in the second embodiment is an improvement on the above embodiment, and the technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0055] See also Figure 1 and Figure 2 As shown, in an optional scheme of this embodiment, the material preparation workshop 101 is also provided with a ton bag loading mechanism; the ton bag loading mechanism includes a loading vehicle 122, an elevator 123 and a conveyor line 124; the elevator 123 can be docked with the loading vehicle 122 to lift the pallet carrying the ton bag 106 to the height of the unpacking station 103; the elevator 123 can be docked with the conveyor line 124, so that the conveyor line 124 transports the pallet to the side of the unpacking station 103.

[0056] Specifically, before executing the batching process, the material preparation process needs to be executed first. The material preparation process is as follows: the powder central control system predicts in advance whether material preparation is needed based on the storage material levels of the main material metering bin 105 and the auxiliary material metering bin 113 in the batching area. If the storage weight has reached the material preparation warning level, the central control system initiates the material preparation demand, and the AGV scheduling system dispatches the AGV to transfer the designated ton bag pallet from the powder line side bin to the top of the elevator 123 in the unpacking area. The elevator 123 lifts the powder pallet to the conveyor line 124 flush with the unpacking station 103, and the conveyor line 124 transfers the ton bag 106 to the designated unpacking station 103. The ton bag 106 is transferred to the unpacking station 103 by automatic logistics. There is no need for manual assistance to transport the ton bag 106 below the unpacking station 103, which can reduce labor costs and reduce employee labor intensity.

[0057] Furthermore, the ton-bag loading mechanism also includes a traveling crane 125 , which is detachably connected to the ton-bag 106 to transport the ton-bag 106 on the conveyor line 124 to the upper part of the unpacking station 103 .

[0058] In this embodiment, the ton bag 106 can be transferred to the top of the unpacking station 103 by manually operating the overhead crane 125. The manual unpacking and blanking time is about 60 seconds, the negative pressure conveying speed is about 100kg / min, the weight of a single ton bag 106 is 400kg, and the conveying is completed in 240 seconds. The powder is temporarily stored in the unpacking temporary storage bin 104. After the manual unpacking and blanking is completed, the packaging materials of the ton bag 106 can be processed and prepared for the next ton bag 106 to be fed. At the same time, the unpacking temporary storage bin 104 sends the materials to the main material metering bin 105, which greatly improves the material preparation efficiency.
