[0021] Among them, the cleaning particles are driven by the magnetic field to enter the grooves and complex areas of the spiral joint for deep cleaning, avoiding surface scratches caused by mechanical grinding. At the same time, a compressed air-driven air drying device is used to remove chemical cleaning residues and particles to ensure that the joint surface is dry and clean. The cleaning particles can be recycled and reused through a centrifugal separator, reducing material consumption and operating costs during the cleaning process. The overall structural design is compact and reasonable, and the operation is efficient. It can not only thoroughly clean the joint surface, but also protect its integrity, effectively solving the problems of incomplete cleaning, surface damage and impact on rapid detection in the prior art, ensuring the accuracy and reliability of subsequent performance testing of lithium batteries, while improving the detection efficiency to meet high standards of cleaning and testing needs.

[0022] The pre-treatment assembly 4 further comprises a pair of mutually symmetrical storage blocks 41 mounted at the bottom end of the movable plate 34 , wherein a cleaning box, a recovery box and a washing box are respectively mounted in the storage blocks 41 .

[0023] A cleaning liquid is arranged in the cleaning box, cleaning particles are arranged in the cleaning liquid, and a diaphragm pump is installed in the cleaning box.

[0024] The material of the cleaning particles is set to be ferrite material, and the outer surface of the cleaning particles is coated with either a silicon dioxide coating or an aluminum oxide coating.

[0025] A pretreatment block 42 is fixedly connected to the bottom end of the storage block 41, and a pair of pretreatment cylinders 43 that are symmetrical to each other and match the electrode connector 21 are installed on the pretreatment block 42. A sealing capsule is installed at the bottom end of the pretreatment cylinder 43, and an electromagnetic coil is installed outside the pretreatment cylinder 43. An air pump is installed on the pretreatment block 42, and the air pump is connected to the sealing capsule through a conduit.

[0026] The cleaning box, the recovery box and the washing box are all connected to the pretreatment cylinder 43 through a hose, a screw pump and a centrifugal separator are installed in the recovery box, deionized water is provided in the washing box, and a peristaltic pump is installed in the washing box.

[0027] The inner wall of the pretreatment cylinder 43 is inlaid with a plurality of elastic bags 47 , an elastic rod 48 is fixedly connected inside the elastic bag 47 , an abutment ball 49 is fixedly connected to one end of the elastic rod 48 , and the abutment ball 49 is filled with magnetic powder.

[0028] Among them, the pretreatment component 4 realizes the storage, transportation, recovery and subsequent cleaning operations of the cleaning liquid through a pair of mutually symmetrical storage blocks 41. The bottom of the storage block 41 is fixedly connected with a cleaning box, a recovery box and a cleaning box respectively. The cleaning box stores cleaning liquid, and the cleaning liquid is mixed with cleaning particles of ferrite material, and the outer surface of the cleaning particles is coated with a silicon dioxide coating or an aluminum oxide coating to enhance the wear resistance and corrosion resistance of the particles, while reducing scratches or wear generated when cleaning the surface of the electrode joint 21. Through the diaphragm pump installed in the cleaning box, the cleaning liquid can be evenly transported to the inside of the pretreatment cylinder 43 on the pretreatment block 42, thereby realizing the precise supply of the cleaning liquid.

[0029] A pair of mutually symmetrical pretreatment cylinders 43 are installed on the pretreatment block 42. The shape design matches the electrode joint 21 and can be accurately mounted on the outside of the electrode joint 21 during operation. A sealing capsule is installed at the bottom of the pretreatment cylinder 43. The sealing capsule is connected to the air pump on the pretreatment block 42 through a conduit. When the air pump is started, the sealing capsule is inflated, so that the pretreatment cylinder 43 and the electrode joint 21 form a closed cleaning environment to prevent the leakage of cleaning liquid or particles. In addition, an electromagnetic coil is installed outside the pretreatment cylinder 43. The dynamic magnetic field generated by the electromagnetic coil can drive the magnetic particles in the cleaning liquid to move in a directional manner. The magnetic particles produce friction, grinding or impact on the electrode surface, which can effectively remove the oxide layer and stains on the surface of the electrode joint 21, and significantly improve the cleaning efficiency.

[0030] The cleaning box, recovery box and cleaning box are connected to the pretreatment cylinder 43 through a hose. The cleaning liquid after cleaning flows into the recovery box through the hose. A screw pump and a centrifugal separator are installed in the recovery box. The screw pump is used to transport the cleaning liquid to the centrifugal separator. The centrifugal separator can separate the magnetic cleaning particles from the cleaning liquid through centrifugal force to achieve the recycling and reuse of the particles. The cleaning liquid can be used for subsequent cleaning or discharge to reduce resource waste. Deionized water is stored in the cleaning box, and the deionized water is transported to the pretreatment cylinder 43 through a peristaltic pump for secondary cleaning of the electrode connector 21.

[0031] When deionized water is released, the electromagnetic coil installed around the pretreatment cylinder 43 is activated to generate a force on the abutment ball 49 inside the pretreatment cylinder. The magnetic field of the electromagnetic coil acts on the magnetic powder filled inside the abutment ball 49, generating a magnetic repulsive force, causing the abutment ball 49 to produce a periodic or continuous squeezing action in the pretreatment cylinder 43, thereby pushing the elastic bag 47 to move.

[0032] When deionized water is delivered to the interior of the pretreatment cylinder through the peristaltic pump, the electromagnetic coil is started and a dynamic magnetic field is applied, which generates a force on the magnetic powder in the abutment ball 49. This force causes the abutment ball 49 to periodically or continuously squeeze the elastic capsule 47, thereby disturbing and shaking the deionized water in the elastic capsule. The shaking of the water enhances the flushing effect on the surface of the electrode connector 21, thereby further removing residual cleaning liquid and particulate matter.

[0033] When the electromagnetic coil is used to drive the cleaning particles, due to the presence of the elastic rod 48, the elastic rod forms a binding force on the abutment ball 49, making it difficult for the magnetic field to overcome the binding of the elastic rod. Therefore, the cleaning particles move under the action of the magnetic field, but the abutment ball 49 remains stable and does not squeeze the elastic bag.

[0034] When deionized water is released, the electromagnetic coil increases the current and strengthens the magnetic field, thereby generating a greater magnetic repulsion force on the magnetic powder in the abutment ball 49, overcoming the constraint of the elastic rod 48 and causing the abutment ball to move. This movement causes the deionized water to be disturbed during cleaning, thereby cleaning the electrode joint 21 more effectively.

[0035] During the cleaning particle driving stage, the liquid in the pretreatment cylinder is cleaning liquid, not deionized water. If the abutment ball 49 moves at this time, it will squeeze the elastic bag 47 and disturb the cleaning liquid, causing the movement of the cleaning particles to be affected by the liquid disturbance, thereby reducing the cleaning efficiency of the particles. This problem can be avoided by the above method.

[0036] It should be noted that the cleaning particles are made of ferrite, and the particle size is set between 10 microns and 1 mm to meet different cleaning needs. After cleaning, the cleaning liquid and cleaning particles flow into the recovery box through a hose, and the screw pump transports the mixed liquid to the centrifugal separator. The centrifugal separator uses the centrifugal force generated by high-speed rotation to separate the denser ferrite cleaning particles from the cleaning liquid. The cleaning particles are collected at the bottom of the separator and recycled and stored, and the cleaning liquid is discharged back to the cleaning box through the outlet pipe for recycling, thereby achieving efficient separation and reuse of the cleaning particles.

[0037] The main purpose of coating the outer surface of the cleaning particles with a silica coating or an alumina coating is to protect the surface of the electrode joint 21 while enhancing the durability and cleaning efficiency of the particles. Silica has a lower hardness and is softer than alumina. It is suitable for cleaning delicate surfaces and reducing mechanical damage to the surface of the electrode joint. It is particularly suitable for scenarios with thinner oxide layers or strict protection requirements for the electrode surface.

[0038] Aluminum oxide has high hardness and can effectively remove thick oxide layers or stubborn dirt. It is suitable for cleaning rough or severely oxidized electrode joint surfaces. You can choose according to actual needs.

[0039] If one subsequently wants to determine whether magnetic particles exist on the surface of the electrode connector 21 , a Hall element may be installed to detect the presence of magnetic particles, thereby determining the presence of magnetic particles.

[0040] Through the coordinated work of the cleaning box, the recovery box and the cleaning box, efficient supply of cleaning liquid, recycling of particles and deep cleaning of the electrode joint 21 are achieved, which not only improves the cleaning efficiency of the electrode joint and reduces the waste of cleaning liquid and particles, but also the dynamic movement of the magnetic particles driven by the electromagnetic coil makes the cleaning process more efficient and can meet the high-standard cleaning requirements for complex connecting components during the lithium battery cleaning process.

[0041] A pair of mutually symmetrical sealing cylinders 44 are fixedly connected at one end of the transverse column 32 , a sealing rod 45 is slidably connected inside the sealing cylinder 44 , and the bottom end of the sealing rod 45 is fixedly connected to the top end of the storage block 41 .

[0042] A one-way valve is installed at the top of the sealing cylinder 44 , and a drying tube 46 connected to the sealing cylinder 44 is installed at one end thereof. The drying tube 46 is arranged at one side of the electrode joint 21 .

[0043] Among them, a pair of mutually symmetrical sealing cylinders 44 are fixedly connected at one end of the transverse column 32, a sealing rod 45 is slidably connected in the sealing cylinder 44, and the bottom end of the sealing rod 45 is fixedly connected to the top of the storage block 41, forming a structure that can produce compression and release effects as the storage block 41 moves. A one-way valve is installed at the top of the sealing cylinder 44 to control the one-way flow of gas, and a drying tube 46 connected to the sealing cylinder 44 is installed at one end. The drying tube 46 is arranged on one side of the electrode joint 21 to guide the airflow to the surface of the electrode joint to achieve rapid air drying.

[0044] When the storage block 41 moves upwards driven by the hydraulic rod 33, the sealing rod 45 slides upwards together with the storage block 41 and compresses the air inside the sealing cylinder 44. The compressed air is guided to the surface of the electrode joint 21 through the drying tube 46 of the sealing cylinder 44 for air drying. During the drying process, the air flow rate is fast, which can effectively blow away the residual moisture or cleaning liquid on the electrode joint 21 to ensure that the surface of the electrode joint is dry. Due to the function of the one-way valve, there will be no backflow when the storage block 41 moves downward, and the air can be re-absorbed into the sealing cylinder 44 to prepare for the next compression and air drying.

[0045] By cooperating with the sealing tube 44 and the drying tube 46 and utilizing the movement of the transverse column 32 to provide mechanical compressed air, rapid discharge of airflow is achieved, which can effectively remove residual liquid or moisture on the surface of the electrode connector 21 and greatly shorten the air drying time.

[0046] The sealing cylinder 44 has a built-in sliding sealing rod 45, which utilizes the movement of the storage block 41 to directly drive the compression and release of air, without the need for additional energy consumption or independent air drying equipment, and has a simple structure and is energy-saving.

[0047] The drying tube 46 is arranged on one side of the electrode joint 21, and can provide directional airflow to avoid unnecessary airflow disturbance affecting other components, while ensuring that the airflow covers the key area of ​​the electrode joint to achieve uniform air drying.

[0048] The entire air-drying process does not require additional electricity or compressed gas equipment. Airflow is supplied only through mechanical action, reducing energy consumption.

[0049] After the spiral electrode connector 21 is cleaned and air-dried, the lithium battery 2 enters the detection stage, and the detection component 5 performs a comprehensive electrical performance test on it. The detection component 5 consists of a detection block 51 and a pair of mutually symmetrical detection fixtures 52. The detection fixture 52 can accurately dock and clamp the electrode connector 21 to ensure the stability and reliability of the contact. In conjunction with the rapid test device body 1, a variety of electrical performance detection devices are built in, including a conductivity test module, a contact resistance measurement module, and a voltage and current detection module, which can quickly obtain the conductivity of the electrode connector, the contact resistance value, and the output performance of the lithium battery and other key parameters. This technology belongs to the prior art and will not be repeated here.

[0050] Since the oxide layer, dirt and cleaning liquid residue have been completely removed from the surface of the electrode connector during the previous cleaning and air-drying process, the contact between the detection fixture 52 and the electrode connector 21 is closer, avoiding detection errors caused by poor contact or interference from pollutants, thereby significantly improving the accuracy and repeatability of the detection data. The entire detection process has a high degree of automation, and can quickly complete the performance evaluation of the lithium battery, ensure the pass rate of the lithium battery, and provide reliable data support for subsequent assembly or use.

[0051] Working principle: Through the coordinated action of the rapid testing device body 1, the driving component 3, the pretreatment component 4 and the detection component 5, the intelligent quick-change detection of the lithium battery 2 is realized. First, the lithium battery 2 is transported to the detection position through the conveyor belt 12, and the hydraulic rod 33 in the driving component 3 drives the movable plate 34 to move downward, so that a pair of mutually symmetrical pretreatment cylinders 43 in the pretreatment component 4 are accurately mounted on the spiral electrode connector 21 of the lithium battery 2. Subsequently, the sealing bag of the pretreatment cylinder 43 is inflated by an air pump to form a closed space with the electrode connector 21. The cleaning liquid and ferrite cleaning particles in the cleaning box are transported to the inside of the pretreatment cylinder 43 under the action of the diaphragm pump. At the same time, the electromagnetic coil generates a dynamic magnetic field to drive the cleaning particles to efficiently clean the surface of the spiral electrode connector 21, and remove the oxide layer and dirt by friction. The cleaning liquid and particles are then transported to the recovery box by a hose. The screw pump and centrifugal separator in the recovery box realize the separation and recovery of magnetic particles. Subsequently, the deionized water in the cleaning box is transported to the pretreatment cylinder 43 through a peristaltic pump, and the electromagnetic coil acts on the magnetic powder in the abutment ball 49, so that the abutment ball produces periodic squeezing on the elastic capsule 47, enhancing the disturbance effect of the deionized water, thereby further removing the residual cleaning liquid and particulate matter. After the cleaning is completed, the pretreatment component 4 stops working, and the driving component 3 moves the movable plate 34 upward and resets. At the same time, the sealing rod 45 in the sealing cylinder 44 moves with the storage block 41 to generate compressed air, and the airflow is directed to the surface of the electrode joint 21 through the drying tube 46 for air drying, ensuring that there is no residual liquid or particles on the joint surface. Finally, the detection component 5 is started, and the detection fixture 52 clamps the electrode joint 21. The conductive performance, contact resistance and output performance of the lithium battery 2 of the electrode joint are quickly detected through the detection block 51. The whole process is efficient and automated, ensuring the cleaning quality and detection accuracy of the lithium battery 2.
