Description

Technical Field

[0001] The present invention relates to the technical field of quick-change test devices, and more specifically, to an intelligent quick-change test device for lithium batteries. Background Art

[0002] The electrode connector of a lithium battery is an important component for connecting the electrode to an external circuit. Common forms include planar, columnar, and spiral connectors. Among them, the spiral electrode connector is widely used in high-performance lithium batteries, such as electric vehicles and energy storage systems, due to its advantages of increasing the contact area, reducing resistance, and optimizing heat dissipation. At the same time, the spiral electrode connector of a lithium battery is an important component for connecting the internal electrode of the battery to the external circuit. Its surface is prone to generating an oxide layer due to long-term exposure to air, which will affect the electrical conductivity and contact quality of the electrode. In the production and maintenance of lithium batteries, to ensure the battery performance and connection reliability, it is usually necessary to clean the surface of the electrode connector, remove the oxide layer, and then perform performance testing.

[0003] Since an oxide layer has already appeared on the surface of the spiral electrode connector, it must be removed before subsequent performance testing of the lithium battery. However, existing cleaning methods usually use mechanical grinding or chemical agent cleaning, which have many drawbacks: mechanical grinding is likely to damage the surface structure of the electrode connector, especially the spiral groove area is difficult to clean thoroughly; although chemical agent cleaning has a high cleaning efficiency, it is easy to leave chemical residues, interfering with subsequent electrical performance testing and affecting the rapidity and accuracy of the testing. Existing technologies are difficult to balance cleaning efficiency and electrode surface protection, which is not conducive to the rapid testing and quality assessment of lithium batteries.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment:

[0029] Please refer to Figures 1-6 , an intelligent quick-change testing device for lithium batteries, comprising: the main body 1 of the rapid testing device, the lithium battery 2, the driving component 3, the pretreatment component 4 and the detection component 5. A pair of symmetrically arranged support bases 11 are fixedly connected to the bottom end of the main body 1 of the rapid testing device, and a conveyor belt 12 is arranged at the top end of the main body 1 of the rapid testing device. A plurality of uniformly distributed lithium batteries 2 are installed on the conveyor belt 12; a pair of symmetrically arranged electrode connectors 21 are installed on the lithium battery 2, and the corresponding shape of the electrode connector 21 is set to be spiral; the driving component 3 is installed on the main body 1 of the rapid testing device. The driving component 3 includes a driving column 31, the bottom end of the driving column 31 is fixedly connected to the top end of the main body 1 of the rapid testing device, the top end of the driving column 31 is fixedly connected to a transverse column 32, a hydraulic rod 33 is installed at the bottom end of the transverse column 32, and the output end of the hydraulic rod 33 is fixedly connected to a moving plate 34; the pretreatment component 4 is installed on the moving plate 34, and the pretreatment component 4 is used to preprocess the lithium battery 2; the detection component 5 is installed on the moving plate 34, and the detection component 5 includes a detection block 51, the detection block 51 is fixedly connected to the moving plate 34, and a pair of symmetrically arranged detection fixtures 52 are installed on the detection block 51.

[0030] Among them, the cleaning particles are driven by a magnetic field to enter the grooves and complex areas of the spiral joint for deep cleaning, avoiding surface scratches caused by mechanical polishing. At the same time, an air-drying device driven by compressed air is used to remove chemical cleaning residues and particles, ensuring that the surface of the joint is dry and clean. The cleaning particles can be recycled through a centrifugal separator, reducing material consumption and operating costs during the cleaning process. The overall structure is designed compactly and reasonably, with efficient operation. It can not only thoroughly clean the surface of the joint but also protect its integrity, effectively solving the problems of incomplete cleaning, surface damage, and affecting rapid detection in the existing technology, ensuring the accuracy and reliability of the subsequent performance detection of lithium batteries. At the same time, it improves the detection efficiency and meets the high-standard cleaning and detection requirements.

[0031] The pretreatment assembly 4 further includes a pair of symmetrically arranged storage blocks 41 installed at the bottom end of the moving plate 34. A cleaning tank, a recycling tank, and a cleaning tank are respectively installed in the storage blocks 41.

[0032] A cleaning liquid is provided in the cleaning tank, cleaning particles are provided in the cleaning liquid, and a diaphragm pump is installed in the cleaning tank.

[0033] The cleaning particles are made of ferrite material, and a silica coating or an alumina coating is coated on the outer surface of the cleaning particles.

[0034] The bottom end of the storage block 41 is fixedly connected with a pretreatment block 42. A pair of symmetrically arranged pretreatment cylinders 43 that match the electrode joint 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.

[0035] The cleaning tank, the recycling tank, and the cleaning tank are all connected to the pretreatment cylinder 43 through hoses. A screw pump and a centrifugal separator are installed in the recycling tank. Deionized water is provided in the cleaning tank, and a peristaltic pump is installed in the cleaning tank.

[0036] A plurality of elastic capsules 47 are inlaid on the inner wall of the pretreatment cylinder 43. An elastic rod 48 is fixedly connected in the elastic capsule 47. One end of the elastic rod 48 is fixedly connected with a contact ball 49, and magnetic powder is filled in the contact ball 49.

[0037] Among them, the pretreatment component 4 realizes the storage, transportation, recycling and subsequent cleaning operations of the cleaning liquid through a pair of symmetric storage blocks 41. The bottom ends of the storage blocks 41 are fixedly connected to a cleaning tank, a recycling tank and a cleaning tank respectively. The cleaning tank stores the cleaning liquid, and the cleaning liquid is mixed with cleaning particles made of ferrite material. 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, and at the same time reduce the scratches or abrasions generated when cleaning the surface of the electrode connector 21. By installing a diaphragm pump in the cleaning tank, the cleaning liquid can be evenly transported into the pretreatment cylinder 43 on the pretreatment block 42, so as to achieve the precise supply of the cleaning liquid.

[0038] A pair of symmetric pretreatment cylinders 43 are installed on the pretreatment block 42, and their shape is designed to match the electrode connector 21 and can be accurately sleeved outside the electrode connector 21 during operation. A sealing capsule is installed at the bottom end of the pretreatment cylinder 43, and 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 a closed cleaning environment is formed between the pretreatment cylinder 43 and the electrode connector 21 to avoid the leakage of the cleaning liquid or particles. In addition, an electromagnetic coil is installed outside the pretreatment cylinder 43. Through the dynamic magnetic field generated by the electromagnetic coil, the magnetic particles in the cleaning liquid can be driven to move directionally. The magnetic particles generate friction, grinding or impact on the electrode surface, which can effectively remove the oxide layer and stains on the surface of the electrode connector 21 and significantly improve the cleaning efficiency.

[0039] The cleaning tank, the recycling tank and the cleaning tank are connected to the pretreatment cylinder 43 through hoses. After cleaning, the cleaning liquid flows into the recycling tank through the hoses. A screw pump and a centrifugal separator are installed in the recycling tank. 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 by centrifugal force to realize the recycling of the particles. The cleaning liquid can be used for subsequent cleaning or discharge to reduce resource waste. The cleaning tank stores deionized water, and the deionized water is transported to the pretreatment cylinder 43 through a peristaltic pump for secondary cleaning of the electrode connector 21.

[0040] When releasing the deionized water, by starting the electromagnetic coil installed outside the pretreatment cylinder 43, an acting force is generated on the abutting ball 49 inside the pretreatment cylinder. The magnetic field of the electromagnetic coil acts on the magnetic powder filled inside the abutting ball 49 to generate a magnetic repulsive force, so that the abutting ball 49 generates periodic or continuous extrusion actions inside the pretreatment cylinder 43, thereby pushing the elastic capsule 47 to displace.

[0041] When deionized water is transported into the interior of the pretreatment cylinder by a peristaltic pump, the electromagnetic coil is activated and a dynamic magnetic field is applied, generating a force on the magnetic powder within the abutting ball 49. This force causes the abutting ball 49 to exert periodic or continuous extrusion on the elastic bladder 47, thereby disturbing and agitating the deionized water within the elastic bladder. The agitation of the water enhances the flushing effect on the surface of the electrode connector 21, thereby further removing the residual cleaning liquid and particulate matter.

[0042] 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 abutting ball 49, making it difficult for the magnetic field to overcome the restraint of the elastic rod. Therefore, the cleaning particles move under the action of the magnetic field, but the abutting ball 49 remains stable and does not exert extrusion on the elastic bladder.

[0043] When releasing the deionized water, the electromagnetic coil increases the current and enhances the magnetic field intensity, thereby generating a greater magnetic repulsive force on the magnetic powder within the abutting ball 49, overcoming the constraint of the elastic rod 48, and causing the abutting ball to move. This movement causes the deionized water to be disturbed during cleaning, thereby more effectively cleaning the electrode connector 21.

[0044] During the cleaning particle driving stage, the liquid within the pretreatment cylinder is the cleaning liquid rather than deionized water. If the abutting ball 49 moves at this time, it will squeeze the elastic bladder 47 and disturb the cleaning liquid, resulting in the movement of the cleaning particles being affected by the liquid disturbance and reducing the cleaning efficiency of the particles. The above-mentioned method avoids the occurrence of this problem.

[0045] It should be noted that the cleaning particles are made of ferrite material, and the particle size is set between 10 microns and 1 millimeter to adapt to different cleaning requirements. After cleaning, the cleaning liquid and cleaning particles flow into the recycling 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, while the cleaning liquid is discharged back to the cleaning box through the outlet pipe for recycling, thereby realizing the efficient separation and reuse of the cleaning particles.

[0046] 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 connector 21, while enhancing the durability and cleaning efficiency of the particles. Silica has a lower hardness and is softer than alumina, suitable for cleaning delicate surfaces, reducing mechanical damage to the surface of the electrode connector, and is particularly suitable for scenarios with a thinner oxide layer or strict protection requirements for the electrode surface.

[0047] Alumina has a higher hardness and can effectively remove thicker oxide layers or stubborn dirt, suitable for cleaning the surface of relatively rough or severely oxidized electrode connectors, and is selected according to actual needs.

[0048] Subsequently, if you want to detect whether there are magnetic particles on the surface of the electrode joint 21, you can install a Hall element for detection to make a judgment.

[0049] Through the coordinated work of the cleaning box, the recycling box and the cleaning tank, the efficient supply of the cleaning liquid, the recycling of particles and the deep cleaning of the electrode joint 21 are realized. It not only improves the cleaning efficiency of the electrode joint, reduces the waste of cleaning liquid and particles, but also the electromagnetic coil drives the dynamic movement of magnetic particles, making the cleaning process more efficient, and can meet the high-standard cleaning requirements for complex connecting components in the lithium battery cleaning process.

[0050] One end of the transverse column 32 is fixedly connected with a pair of symmetric sealing cylinders 44. A sealing rod 45 is slidably connected in the sealing cylinder 44, and the bottom end of the sealing rod 45 is fixedly connected with the top end of the storage block 41.

[0051] A one-way valve is installed at the top end of the sealing cylinder 44, and a drying pipe 46 connected thereto is installed at one end of the sealing cylinder 44. The drying pipe 46 is arranged on one side of the electrode joint 21.

[0052] Among them, one end of the transverse column 32 is fixedly connected with a pair of symmetric sealing cylinders 44. A sealing rod 45 is slidably connected in the sealing cylinder 44, and the bottom end of the sealing rod 45 is fixedly connected with the top end of the storage block 41, forming a structure that can be compressed and released as the storage block 41 moves. A one-way valve is installed at the top end of the sealing cylinder 44 to control the one-way flow of gas. A drying pipe 46 connected thereto is installed at one end of the sealing cylinder 44. The drying pipe 46 is arranged on one side of the electrode joint 21 to direct the air flow to the surface of the electrode joint to achieve rapid air drying.

[0053] When the storage block 41 moves upward driven by the hydraulic rod 33, the sealing rod 45 slides upward together with the storage block 41, compresses the air inside the sealing cylinder 44, and the compressed air is directed to the surface of the electrode joint 21 through the drying pipe 46 of the sealing cylinder 44 for air drying. During the drying process, the air flow rate is relatively fast, which can effectively blow off the residual moisture or cleaning liquid on the electrode joint 21 to ensure the dryness of the electrode joint surface. Due to the function of the one-way valve, there is no backflow when the storage block 41 moves downward, and the air inside the sealing cylinder 44 can re-inhale air to prepare for the next compression and air drying.

[0054] Through the cooperation of the sealing cylinder 44 and the drying pipe 46, mechanical compressed air is provided by the movement of the transverse column 32 to realize the rapid discharge of air flow, which can efficiently remove the residual liquid or moisture on the surface of the electrode joint 21 and greatly shorten the air drying time.

[0055] The sealing cylinder 44 is internally provided with a sliding sealing rod 45, which directly drives the compression and release of air by the movement of the storage block 41, without additional energy consumption or independent air drying equipment, and has a simple structure and energy saving.

[0056] The drying tube 46 is arranged on one side of the electrode connector 21, which can provide air flow directionally, avoid the influence of unnecessary air flow disturbance on other components, and at the same time ensure that the air flow covers the key areas of the electrode connector to achieve uniform air drying.

[0057] The entire air drying process does not require additional electrical energy or compressed gas equipment, and the air flow is supplied only through mechanical actions, reducing energy consumption.

[0058] After the cleaning and air drying of the spiral electrode connector 21 are completed, the lithium battery 2 enters the detection stage, and the detection component 5 conducts a comprehensive electrical performance detection on it. The detection component 5 consists of a detection block 51 and a pair of symmetric detection jigs 52. The detection jigs 52 can accurately dock and clamp the electrode connector 21 to ensure the stability and reliability of the contact. Cooperating with the main body 1 of the rapid test device, there are various electrical performance detection devices built in, including a conductivity test module, a contact resistance measurement module, and voltage and current detection modules, which can quickly obtain key parameters such as the conductivity of the electrode connector, the contact resistance value, and the output performance of the lithium battery. This technology belongs to the prior art and will not be elaborated here.

[0059] Since the oxide layer, dirt and cleaning liquid residues have been completely removed from the surface of the electrode connector during the previous cleaning and air drying processes, the contact between the detection jig 52 and the electrode connector 21 is closer, avoiding detection errors caused by poor contact or pollutant interference, thus significantly improving the accuracy and repeatability of the detection data. The entire detection process has a high degree of automation, can quickly complete the performance evaluation of the lithium battery, ensure the qualification rate of the lithium battery, and provide reliable data support for the subsequent assembly or use links.

[0060] Working principle:

[0061] Through the coordinated action of the main body 1 of the rapid testing device, 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 conveyed to the detection position through the conveyor belt 12. The hydraulic rod 33 in the driving component 3 drives the moving plate 34 to move downward, so that a pair of symmetrically arranged pretreatment cylinders 43 in the pretreatment component 4 are accurately sleeved on the spiral electrode connectors 21 of the lithium battery 2. Subsequently, the sealing capsule of the pretreatment cylinder 43 is inflated by the air pump to form a sealed space with the electrode connector 21. The cleaning liquid and the cleaning particles made of ferrite material in the cleaning tank are conveyed into the interior 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, removing the oxide layer and dirt through friction. The cleaning liquid and particles are then conveyed into the recovery tank by the hose. The screw pump and the centrifugal separator in the recovery tank realize the separation and recovery of the magnetic particles. Subsequently, the deionized water in the cleaning tank is conveyed into the pretreatment cylinder 43 through the peristaltic pump. By the electromagnetic coil acting on the magnetic powder in the abutting ball 49, the abutting ball periodically squeezes the elastic capsule 47, enhancing the disturbance effect of the deionized water, so as to further remove 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 moving plate 34 upward to reset. At the same time, the sealing rod 45 in the sealing cylinder 44 generates compressed air as it moves with the storage block 41, and the air flow is directed to the surface of the electrode connector 21 through the drying pipe 46 for air drying to ensure that there is no residual liquid or particle on the surface of the connector. Finally, the detection component 5 is started, the detection fixture 52 clamps the electrode connector 21, and the detection block 51 quickly detects the conductivity, contact resistance of the electrode connector, and the output performance of the lithium battery 2. The whole process is efficient and automated, ensuring the cleaning quality and detection accuracy of the lithium battery 2.
