Description

Technical Field

[0001] This utility model belongs to the field of battery processing technology, specifically relating to an automatic electrode feeding and installation device. Background Technology

[0002] This process relies on manual placement. Multiple battery cells are assembled according to their positive and negative electrode surfaces and then pushed into a cell assembly mold by a cylinder for positioning. Operators then manually place the pre-processed single positive electrode sheet into the positive electrode surface of the assembled cell and the pre-processed single negative electrode sheet into the negative electrode surface. The next processing step is then performed. The fit between the positive and negative electrode sheets and the cell assembly mold is as follows: Figure 1 As shown.

[0003] This manual placement method has many drawbacks:

[0004] High production costs: Since the production equipment has a production speed of about 90 pieces per minute, in order to meet the production needs, two people on each side (a total of four people) are required to operate the positive and negative electrode plates at the same time, which results in high labor costs.

[0005] Product quality is affected: Manual placement of electrode sheets requires human contact, which can easily cause damage, oxidation, and contamination. Moreover, operators may accidentally place the electrode sheets on the wrong side if they are not careful, which seriously affects the quality of battery products.

[0006] The process is labor-intensive and inefficient: The production equipment operates continuously, requiring operators to place one positive and one negative electrode sheet on each of the positive and negative electrode faces of each group of cells, a repetitive and frequent task that is extremely labor-intensive. Sometimes, operators may inadvertently place both electrode sheets on one electrode face of the cell, requiring the machine to be stopped and one of the sheets removed before proceeding to the next process, resulting in low production efficiency. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides an automatic electrode feeding and installation device to solve the problems of high production costs, affected product quality, high labor intensity, and low production efficiency caused by the reliance on manual operation for electrode feeding and installation in the prior art, thereby achieving accurate and efficient feeding and installation of electrodes in the battery assembly production line.

[0008] This utility model provides an automatic electrode feeding and installation device for installing electrodes into a battery cell assembly mold. It includes a battery cell assembly mold conveyor chain, a vibratory feeder, a feeding guide groove, a first positioning cylinder, a second positioning cylinder, a turntable mechanism, and a first pushing cylinder. The vibratory feeder is used for electrode discharge. The top of the feeding guide groove is connected to the discharge port of the vibratory feeder. The turntable mechanism includes a rotation drive mechanism and a turntable. The rotation drive mechanism is connected to the turntable. Multiple magnets are spaced circumferentially along the side of the turntable. Feeding devices are located at different positions on the turntable. The feeding and discharging stations are connected by a rotary drive mechanism that drives the turntable to rotate, causing multiple magnets to rotate between the feeding and discharging stations. The bottom of the feeding guide trough is located at the feeding station. The first positioning cylinder and the second positioning cylinder are vertically spaced on the bottom sidewall of the feeding guide trough. The cell assembly mold conveying chain is located below the discharging station and is used to transport the cell assembly mold to the area below the discharging station. The first pushing cylinder is located above the discharging station.

[0009] Furthermore, there are two of each of the vibratory feeder, the feeding guide chute, the first positioning cylinder, the second positioning cylinder, and the turntable mechanism. The two vibratory feeders, the two feeding guide chute, the two first positioning cylinders, the two second positioning cylinders, and the two turntable mechanisms are arranged in a one-to-one correspondence. The two vibratory feeders are used to transport the positive electrode sheet and the negative electrode sheet respectively, and the discharge stations of the two turntables are located above the same position on the cell assembly mold conveyor chain.

[0010] Furthermore, it also includes a second pushing cylinder, which and the first pushing cylinder are sequentially and spaced apart above the battery cell assembly mold conveyor chain along the conveying direction of the battery cell assembly mold conveyor chain.

[0011] Furthermore, it also includes a material monitoring sensor, which is located at the end of the cell assembly mold conveyor chain and is used to detect whether there are electrode sheets in the cell assembly mold.

[0012] This automatic electrode feeding and installation device achieves automatic electrode feeding and installation through the coordination of a vibratory feeder, a feeding guide trough, a turntable mechanism, and positioning and pushing cylinders. This reduces manual operation and lowers labor costs. Simultaneously, it avoids human contact with the electrodes, reducing the risk of electrode damage, oxidation, and contamination, thus improving product quality. Attached Figure Description

[0019] This utility model discloses an automatic electrode feeding and installation device, which realizes accurate and efficient feeding and installation of electrode sheets in the battery assembly production line.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of the embodiments of this utility model, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] See Figures 2-5As shown, this utility model discloses an automatic electrode feeding and installation device for installing electrodes into a cell assembly mold 3. It includes a cell assembly mold conveyor chain 12, a vibratory feeder 7, a feeding guide 6, a first positioning cylinder 5, a second positioning cylinder 4, a turntable mechanism, and a first pushing cylinder 8. The vibratory feeder 7 is used for electrode discharge. The top of the feeding guide 6 is connected to the discharge port of the vibratory feeder 7. The turntable mechanism includes a rotation drive mechanism 11 and a turntable 10. The rotation drive mechanism 11 is connected to the turntable 10. Multiple magnets 16 are spaced circumferentially along the side of the turntable 10. Feeding stations 1 are set at different positions on the turntable 10. 4 and the discharge station 15, the rotary drive mechanism 11 drives the turntable 10 to rotate, so that the multiple magnets 16 rotate between the feeding station 14 and the discharge station 15. The bottom of the feeding guide 6 is located at the feeding station 14. The first positioning cylinder 5 and the second positioning cylinder 4 are arranged vertically at intervals on the bottom side wall of the feeding guide 6. The cell assembly mold conveying chain 12 is located below the discharge station 15. The cell assembly mold conveying chain 12 is used to transport the cell assembly mold 3 to the bottom of the discharge station 15. The first pushing cylinder 8 is located above the discharge station 15.

[0022] The number of the vibratory feeder 7, the feeding guide 6, the first positioning cylinder 5, the second positioning cylinder 4, and the turntable mechanism are all two, and the two vibratory feeders 7, the two feeding guide 6, the two first positioning cylinders 5, the two second positioning cylinders 4, and the two turntable mechanisms are arranged in a one-to-one correspondence. The two vibratory feeders 7 are used to transport the positive electrode sheet 1 and the negative electrode sheet 2, respectively, and the discharge stations 15 of the two turntables 10 are located above the same position of the cell assembly mold conveyor chain 12.

[0023] Two identical feeding and installation components are set up for conveying and installing the positive electrode 1 and the negative electrode 2 respectively. This allows for simultaneous electrode installation on the positive and negative surfaces of the cell assembly mold 3, improving the efficiency of feeding and installation and meeting the needs of high-efficiency production on the production line.

[0024] The automatic electrode feeding and installation device further includes a second pushing cylinder 9, and the second pushing cylinder 9 and the first pushing cylinder 8 are arranged sequentially and at intervals above the battery cell assembly mold conveying chain 12 along the conveying direction of the battery cell assembly mold conveying chain 12.

[0025] Two pusher cylinders work in sequence. First, the first pusher cylinder 8 pushes a portion of the electrode sheet into the cell assembly mold 3, and then the second pusher cylinder 9 pushes the electrode sheet completely into the mold. This allows the electrode sheet to be installed more stably and accurately into the cell assembly mold 3, further improving the accuracy of electrode sheet installation, reducing the occurrence of electrode sheet misinstallation, and improving product quality.

[0026] The automatic electrode feeding and installation device also includes a material monitoring sensor 13, which is located at the end of the cell assembly mold conveyor chain 12 and is used to detect whether there are electrodes in the cell assembly mold 3.

[0027] The material monitoring sensor 13 can monitor the condition of the electrode sheets in the cell assembly mold 3 in real time. When the electrode sheet is missing or the polarity is incorrect, an alarm can be automatically triggered or the conveying can be paused. Problems in the production process can be detected in time, and the production of unqualified products can be avoided, thus reducing production losses. At the same time, it is convenient to adjust and maintain the equipment in a timely manner, ensuring the continuity and stability of production.

[0028] When the automatic electrode feeding and installation device is in operation, the operator places the processed positive and negative electrodes 1 and 2 into the corresponding vibrating plates 7. The vibrating plates 7 arrange the electrodes, causing them to exit into the discharge guide trough 6 in a certain direction. After a certain number of electrodes are stored in the discharge guide trough 6, the first positioning cylinder 5 limits and fixes the bottom electrode, and the second positioning cylinder 4 limits and fixes the second to last electrode. When the turntable 10 rotates to the feeding station 14, the second positioning cylinder 4 first limits and fixes the second to last electrode, so that the second to last and above electrodes in the trough are in a stationary state. Then, the first positioning cylinder 5 retracts and releases the bottom electrode onto the turntable 10. The magnet 16 on the turntable 10 attracts the electrode, making its metal surface adhere tightly to the outside of the turntable 10, and the electrode rotates to the discharge station 15 as the turntable 10 rotates. At this time, the cell assembly mold conveyor chain 12 transports the cell assembly mold 3 to below the discharge station 15. The first pushing cylinder 8 pushes half of the electrode sheet into the cell assembly mold 3. After the assembled cell and electrode sheet have traveled a certain distance, the second pushing cylinder 9 pushes the electrode sheet completely into the cell assembly mold 3, so that the electrode sheet fully contacts the positive and negative electrode surfaces of the cell, completing the electrode sheet installation process. At the end of the cell assembly mold conveyor chain 12, the material monitoring sensor 13 detects whether there are electrode sheets in the cell assembly mold 3. If a problem is found, an alarm is automatically triggered or the conveying is paused.

[0029] This automatic electrode feeding and installation device achieves automatic electrode feeding and installation through the discharge of the vibrating plate 7, the conveying of the feeding guide 6, the transfer of the turntable mechanism, and the coordination of the positioning cylinder and the pushing cylinder. This reduces manual operation and lowers labor costs. At the same time, it avoids human contact with the electrode, reducing the risk of electrode damage, oxidation, and contamination, and improving product quality.

[0030] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
