Description

Technical Field

[0001] The invention belongs to the technical field of lithium battery detection, in particular to an online detection device for lithium battery production. Background Art

[0002] With the widespread use of potassium batteries in mobile communications and electronic appliances, potassium battery safety accidents have also been exposed frequently. For many electronic manufacturers, lithium battery testing has become a daily task, and there are many reasons for doing this work. Therefore, battery performance testing through a standard system is a way to determine whether the battery is safe and reliable.

[0003] Lithium battery testing requires appearance, electrical, mechanical, thermal and environmental simulation testing. Lithium batteries first need to undergo appearance testing. During the lithium battery testing process, workers first need to install or place the lithium batteries in the testing equipment for loading. If the number of lithium batteries to be tested is large, workers will inevitably make mistakes in loading due to negligence, resulting in incorrect lithium battery test data and reduced lithium battery testing efficiency.

[0004] Secondly, when workers load lithium battery testing equipment, they will conduct a preliminary inspection of the appearance to check whether there are bulges or obvious damage on the surface of the lithium battery. This is because if the electrode coating is uneven or dust particles are mixed into the electrolyte during the production process of the lithium battery, a chemical reaction will occur inside the lithium battery, causing the lithium battery to bulge. The bulging phenomenon of lithium batteries is easily discovered by workers and avoided by workers entering the testing equipment, reducing the detection of defective lithium batteries by the testing equipment. However, this work step increases the work intensity of workers and makes it easy for workers to neglect the initial inspection, allowing some defective lithium batteries with obvious defects to enter the testing equipment, increasing the detection of defective lithium batteries in the testing equipment and reducing the detection efficiency of lithium batteries.

[0025] 1. The present invention discloses an online detection device for lithium battery production. If a bulge appears on the surface of a lithium battery, the bulge on the lithium battery contacts shaft No. 1 during the rotation of the lithium battery, pushing shaft No. 1 in the direction away from each other, and shaft No. 1 drives the sliding block to slide in the slide groove. At this time, the pressure sensor monitoring the sliding block detects the displacement of the sliding block and issues a warning. The networked control platform records and stores its data in the cloud, thereby realizing online detection of lithium batteries, and controlling the extension of telescopic rod No. 1, which prevents shaft No. 1 from moving. Shaft No. 1 drives the sliding block to slide in the slide groove, so that the two shafts No. 1 are misaligned with the driving shaft, and the clamped lithium battery is moved to fall onto the conveyor belt, thereby completing the preliminary detection of the lithium battery appearance, reducing the number of defective lithium batteries detected by subsequent detection modules, and reducing the labor intensity of workers, thereby improving detection efficiency.

[0026] 2. The present invention relates to an online detection device for lithium battery production. When the placement rack moves toward the appearance detection module, the end of the seesaw away from the No. 1 plate gradually rises along the top edge of the placement rack. Through the support and restriction of the support rod, the end of the seesaw close to the No. 1 plate descends, and drives the No. 1 plate to descend along the No. 1 groove. The No. 1 plate descends, squeezes and drives the lithium battery between the sealing plate and the No. 1 plate to descend, until the No. 1 plate squeezes the lithium battery into the gap between the two No. 1 axes in the next placement rack. The two No. 1 axes and the driving axis clamp and fix the lithium battery, thereby completing the loading and installation of the lithium battery, reducing the labor intensity of workers, and allowing workers to have more time to conduct preliminary appearance inspections on the lithium batteries on the conveyor belt, remove some lithium batteries with obvious defects, and improve the inspection efficiency of lithium batteries.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1:

[0039] Lithium battery testing requires appearance, electrical, mechanical, thermal and environmental simulation testing. Lithium batteries first need to undergo appearance testing. During the lithium battery testing process, workers first need to install or place the lithium batteries in the testing equipment for loading. If the number of lithium batteries to be tested is large, workers will inevitably make mistakes in loading due to negligence, resulting in incorrect lithium battery test data and reduced lithium battery testing efficiency.

[0040] Secondly, when workers load lithium battery testing equipment, they will conduct a preliminary inspection of the appearance to check whether there are bulges or obvious damage on the surface of the lithium battery. This is because if the electrode coating is uneven or dust particles are mixed into the electrolyte during the production process of the lithium battery, a chemical reaction will occur inside the lithium battery, which may cause the lithium battery to bulge. The bulging phenomenon of lithium batteries is easy to be discovered by workers and avoided by entering the testing equipment, reducing the detection of defective lithium batteries by the testing equipment. However, this work step increases the work intensity of workers and is prone to the possibility of negligence in preliminary inspections by workers, allowing some defective lithium batteries with obvious defects to enter the testing equipment, increasing the detection of defective lithium batteries in the testing equipment, and reducing the detection efficiency of lithium batteries;

[0041] In order to effectively solve the above problems, as shown in the accompanying drawings of the specification Figure 1-8 As shown, a lithium battery production online detection equipment includes a transmission mechanism 1, an appearance detection module 11, an electrical detection module 12 and a network control platform 13; the transmission mechanism 1 includes a main body 2, the main body 2 is a conventional transmission device main body 2, including a driving device, and the appearance detection module 11 and the electrical detection module 12 are installed on the main body 2; the network control platform 13 is installed on one side of the main body 2; the transmission mechanism 1 is a conventional transmission device in the field; the appearance detection module 11 is used to detect whether the length, diameter, and surface of the lithium battery are damaged; the electrical detection module 12 is used to perform electrical detection such as overcharging and over-discharging on the lithium battery; the network control platform 13 is connected to the transmission mechanism 1, the appearance detection module 11 and the electrical detection module 12, and the network control platform 13 is used to control the transmission mechanism 1, the appearance detection module 11 and the electrical detection module 12 to work together, and the data detected by the appearance detection module 11 and the electrical detection module 12 are recorded online and stored in the cloud; the main body 2 includes:

[0042] The conveyor belt 21 is installed in the main body 2; the main body 2 drives the conveyor belt 21 to move;

[0043] The placing rack 3 is evenly fixed on the conveyor belt 21, and the placing rack 3 is provided with a slide groove 31; a sliding block 32 is slidably connected in the slide groove 31, and a return spring is provided between the sliding block 32 and the slide groove 31, and a return spring with the same parameters is selected between each sliding block 32 and the slide groove 31; a pressure sensor 33 is provided between the sliding block 32 and the slide groove 31, and the pressure sensor 33 is used to detect whether the sliding block 32 has a large distance displacement after the lithium battery is installed, and to transmit data to the network control platform 13;

[0044] A first shaft 34, the first shaft 34 is rotatably connected to the sliding block 32, the first shaft 34 is close to the top of the placement frame 3, and the placement frame 3 is rotatably connected with a driving shaft 35; the number of the first shafts 34 is two, and the driving shaft 35 is located below two adjacent first shafts 34; the two first shafts 34 and the driving shaft 35 form a triangle to surround the lithium battery to fix the lithium battery; when stationary, the two first shafts 34 are close to each other and there is a gap; both ends of the driving shaft 35 pass through the placement frame 3;

[0045] The linkage plate 22 is arranged in the main body 2, and the linkage plate 22 is located at the edge positions of both sides of the conveyor belt 21; the surface of the linkage plate 22 is closely fitted with the surface of the driving shaft 35, and the surface of the linkage plate 22 is rough;

[0046] The bracket 23 is evenly mounted on the main body 2, and a first telescopic rod 24 is provided at one end of the bracket 23; the bracket 23 is provided at a position close to the appearance detection module 11 and the electrical detection module 12 on the main body 2, and the first telescopic rod 24 is connected to the network control platform 13;

[0047] Specific work flow: After the detection equipment is started, the worker places the lithium battery in the gap between two adjacent No. 1 shafts 34, and then presses the lithium battery downward. The lithium battery moves the No. 1 shaft 34 away from each other, and the No. 1 shaft 34 drives the sliding block 32 to slide in the slide groove 31 until the lithium battery is embedded between the two No. 1 shafts 34 and the driving shaft 35. The two No. 1 shafts 34 squeeze and clamp the upper part of the lithium battery, squeeze the lithium battery against the surface of the driving shaft 35, and surround and fix the lithium battery; then the conveyor belt 21 moves to drive the placement rack 3 to move toward the appearance inspection module 11, and the placement rack 3 drives the driving shaft 35 and the No. 1 shaft 34 to move , the driving shaft 35 and the first shaft 34 drive the lithium battery to move in the direction of the appearance detection module 11 for detection, at which time the pressure sensor 33 starts to work and monitors the movement of the sliding block 32; when the placement rack 3 passes through the linkage plate 22 during the movement, the surface of one end of the driving shaft 35 is in close contact with the surface of the linkage plate 22, and as the placement rack 3 drives the driving shaft 35 to move in close contact with the linkage plate 22, the friction between the linkage plate 22 and the surface of the driving shaft 35 generates a force, so that the driving shaft 35 rotates along the surface of the linkage plate 22, the driving shaft 35 contacts the lithium battery and drives it to rotate, and the rotation of the lithium battery drives the first shaft 34 to rotate;

[0048] If a bulge appears on the surface of the lithium battery, during the rotation of the lithium battery, the bulge on the lithium battery contacts the No. 1 shaft 34, pushing the No. 1 shaft 34 in the direction away from each other, and the No. 1 shaft 34 drives the sliding block 32 to slide in the sliding groove 31. At this time, the pressure sensor 33 monitoring the sliding block 32 detects the displacement of the sliding block 32 and issues an alarm. The networked control platform 13 records and stores its data in the cloud to realize online detection of the lithium battery, and controls the No. 1 telescopic rod 24 to extend. When the placement frame 3 moves close to the bracket 23, the No. 1 shaft 34 contacts the extended end of the No. 1 telescopic rod 24, and the placement frame 3 drives the active shaft 35 to continue to move, and the No. 1 telescopic rod 24 is extended. The rod 24 prevents the No. 1 shaft 34 from moving, and the No. 1 shaft 34 drives the sliding block 32 to slide in the slide slot 31, so that the two No. 1 shafts 34 and the driving shaft 35 are in a misaligned state, and the clamped lithium battery is moved to fall onto the conveyor belt 21. Then the network control platform 13 controls the No. 1 telescopic rod 24 to retract, and the reset spring in the slide slot 31 drives the sliding block 32 and the No. 1 shaft 34 to reset. The defective lithium batteries that fall on the conveyor belt 21 are recycled by workers, thereby completing the preliminary detection of the lithium battery appearance, reducing the number of defective lithium batteries detected by the subsequent detection module, while reducing the labor intensity of workers, thereby improving the detection efficiency;

[0049] Furthermore, after the worker installs the lithium battery, the lithium battery moves toward the appearance inspection module 11 and is driven by the No. 1 shaft 34 to rotate. The worker only needs to observe to check the lithium battery with obvious appearance damage, and then turn the No. 1 shaft 34 to trigger the pressure sensor 33, so that the lithium battery with obvious appearance damage can be excluded through the No. 1 telescopic rod 24, so that the worker can more easily perform preliminary inspection on the lithium battery, further reducing the labor intensity of the worker;

[0050] The lithium battery moves toward the appearance inspection module 11 while rotating, and enters the interior of the appearance inspection module 11 after preliminary inspection by the worker. The driving shaft 35 continues to drive the lithium battery to rotate and move, so that the appearance inspection module 11 can inspect the surface of the lithium battery, and when the appearance inspection of the lithium battery is performed, the portion of the placement rack 3 corresponding to the lithium battery will not block the normal inspection work of the appearance inspection module 11; after the appearance inspection of the lithium battery, the lithium battery is driven by the placement rack 3 to the electrical inspection module 12 for electrical inspection, and then the worker collects the qualified lithium batteries for subsequent inspection;

[0051] Through the cooperation between the first shaft 34, the sliding block 32 and the slide groove 31, when it is necessary to detect cylindrical lithium batteries of different diameters in large quantities, the first shaft 34 can be used to move closer or farther away from each other to clamp and fix the cylindrical lithium batteries of different diameters, so that the detection equipment can detect cylindrical lithium batteries of different diameters in the same batch, thereby improving the detection adaptability of the detection equipment to cylindrical lithium batteries of different specifications;

[0052] When the lithium battery is clamped and fixed between the two No. 1 shafts 34 and the driving shaft 35, the positive and negative electrodes of the lithium battery will not touch the placement rack 3 at the same time, preventing the positive and negative electrodes of the lithium battery from contacting the placement rack 3 at the same time, and preventing the lithium battery from discharging through the conduction of the placement rack 3.

[0053] Embodiment 2:

[0054] On the basis of the first embodiment, the surface of the driving shaft 35 is made of rubber material, such as natural rubber; the surface of the driving shaft 35 contacting the lithium battery is made of rubber material;

[0055] Specific working process: as the placement rack 3 drives the active shaft 35 to move in close contact with the linkage plate 22, the friction between the linkage plate 22 and the surface of the active shaft 35 generates a force, so that the active shaft 35 rotates along the surface of the linkage plate 22, and the active shaft 35 contacts the lithium battery and drives it to rotate. By setting the surface of the active shaft 35 to be made of natural rubber material, which has high wear resistance and good anti-slip properties, the active shaft 35 can more easily drive the lithium battery to rotate, and avoid the active shaft 35 from slipping during the process of driving the lithium battery to rotate, which makes it difficult for workers or subsequent appearance inspection modules 11 to detect surface defects of the lithium battery, thereby improving the rotation effect of the lithium battery, and further improving the efficiency of lithium battery appearance inspection.

[0056] Embodiment three:

[0057] The difference between the third embodiment and the second embodiment is that the third embodiment is another technical solution for the material of the driving shaft 35 in the first embodiment. The surface of the driving shaft 35 is made of plastic material, such as a thicker PE film material. When installing or replacing, multiple layers of PE film are wrapped around the surface of the driving shaft 35.

[0058] Specific working process: by setting the surface of the driving shaft 35 to be a PE film, which has the property of adhesion, when the driving shaft 35 contacts and drives the lithium battery to rotate, the driving shaft 35 continuously contacts the surface of the lithium battery, and removes the dust attached to the surface of the lithium battery due to transportation or storage, so as to avoid detection errors caused by excessive dust during the appearance inspection of the lithium battery, resulting in the possibility that a qualified lithium battery will be detected as a defective product with poor appearance, thereby improving the cleanliness of the lithium battery surface and further improving the accuracy of the appearance inspection of the lithium battery.

[0059] Embodiment 4:

[0060] On the basis of the second embodiment, an extrusion plate 36 is provided between adjacent placement racks 3, and the extrusion plate 36 is made of plastic; the extrusion plate 36 is located on the placement rack 3 away from the appearance inspection module 11; the surface of the extrusion plate 36 close to the conveyor belt 21 is the lower end surface, and vice versa is the upper end surface;

[0061] Specific working process: when the placement rack 3 moves to near the bracket 23, the No. 1 shaft 34 contacts the extended end of the No. 1 telescopic rod 24, the placement rack 3 drives the active shaft 35 to continue to move, while the No. 1 telescopic rod 24 prevents the No. 1 shaft 34 from moving, and the No. 1 shaft 34 drives the sliding block 32 to slide in the slide groove 31, so that the two No. 1 shafts 34 and the active shaft 35 form a misaligned state. At this time, the surface of the lithium battery away from the active shaft 35 gradually approaches and contacts the lower end surface of the extrusion plate 36, and the extrusion plate 36 squeezes the lithium battery onto the conveyor belt 21, and cooperates with the surface of the lithium battery close to the conveyor belt 21 without the support of the active shaft 35 to ensure that when the No. 1 shaft 34 moves to the position below the extrusion plate 36, the lithium battery is squeezed out of the gap between the two adjacent No. 1 shafts 34, so that the lithium battery can fall onto the conveyor belt 21 in time after it is away from the active shaft 35, so that the lithium battery that fails the preliminary appearance inspection will not enter the appearance inspection module 11, thereby reducing the number of unqualified lithium batteries in the appearance inspection module 11, thereby improving the inspection efficiency of lithium batteries;

[0062] By setting the extrusion plate 36 to be made of plastic material, such as hard plastic, it is ensured that when the extrusion plate 36 is squeezed out of the gap of the first shaft 34, the extrusion plate 36 and the lithium battery are prevented from rigidly contacting, causing the lithium battery to be over-extruded and deformed, resulting in damage and leakage of internal materials.

[0063] Embodiment five:

[0064] On the basis of the fourth embodiment, a loading hopper 4 is installed on the main body 2 at a position away from the appearance detection module 11, and a No. 1 slot 41 is provided on both sides of the loading hopper 4 near the bottom; a No. 1 plate 42 is slidably connected to the position corresponding to the No. 1 slot 41 in the loading hopper 4, and one end of the No. 1 plate 42 passes through the No. 1 slot 41 and is located outside the loading hopper 4; a return spring is arranged between the No. 1 plate 42 and the No. 1 slot 41; a sealing plate 43 is hinged at the bottom of the loading hopper 4; the opening part of the loading hopper 4 away from the conveyor belt 21 is the loading port, and the opening part close to the conveyor belt 21 is the unloading port, both of which are rectangular, and the cross-sectional area of ​​the loading port is larger than the cross-sectional area of ​​the unloading port, and the width of the unloading port is smaller than the length of the lithium battery, so that when the lithium battery falls from the unloading port, it remains parallel to the No. 1 axis 34; a torsion spring is arranged between the bottom of the loading hopper 4 and the sealing plate 43; the space between the No. 1 plate 42 and the sealing plate 43 can accommodate a lithium battery;

[0065] A support rod 44 is fixedly connected to the side wall of the main body 2 near the upper hopper 4, and a seesaw 45 is hinged on the top of the support rod 44; one end of the seesaw 45 is slidably connected to one end of the No. 1 plate 42; a torsion spring is provided between the support plate and the seesaw 45, and when stationary, the end of the seesaw 45 close to the No. 1 plate 42 is higher than the end away from the No. 1 plate 42;

[0066] The top of the placement rack 3 is tilted;

[0067] The surface of the No. 1 plate 42 corresponding to the conveyor belt 21 is provided with an adhesive coating; the adhesive coating is a layer of glue applied on the surface of the No. 1 plate 42 close to the conveyor belt 21, which has an adhesive effect after the glue solidifies;

[0068] Specific work flow: when loading materials, workers place the lithium batteries to be tested in the upper hopper 4, one of the lithium batteries falls into the position between the No. 1 plate 42 and the sealing plate 43, and the remaining lithium batteries stay in the lower hopper away from the sealing plate 43, so that the lithium batteries stay in the upper hopper 4; when the placement rack 3 moves toward the appearance inspection module 11, the top edge of the placement rack 3 contacts the end of the seesaw 45 away from the No. 1 plate 42, and as the placement rack 3 moves, the end of the seesaw 45 away from the No. 1 plate 42 gradually rises along the top edge of the placement rack 3, and through the support and restriction of the support rod 44, the end of the seesaw 45 close to the No. 1 plate 42 descends, and drives the No. 1 plate 42 to descend along the No. 1 groove 41, and the No. 1 plate 42 descends, squeezing and driving the lithium batteries between the sealing plate 43 and the No. 1 plate 42 to descend, and the lithium The battery No. 1 plate 42 squeezes the sealing plate 43 through the lithium battery, thereby opening the discharge port in the upper hopper 4. By providing an adhesive coating on the surface of the No. 1 plate 42 close to the conveyor belt 21, when the No. 1 plate 42 drives the lithium battery to descend, the lithium battery adheres to the surface of the No. 1 plate 42 and does not fall on the conveyor belt 21; then the end of the seesaw 45 close to the No. 1 plate 42 drives the No. 1 plate 42 to continue to descend until the No. 1 plate 42 squeezes the lithium battery into the gap between the two No. 1 shafts 34 in the next placement rack 3, and the two No. 1 shafts 34 and the driving shaft 35 clamp and fix the lithium battery, thereby completing the loading and installation of the lithium battery, reducing the labor intensity of the workers, allowing the workers to have more time to conduct a preliminary appearance inspection of the lithium batteries on the conveyor belt 21, remove some lithium batteries with obvious defects, and improve the inspection efficiency of lithium batteries;

[0069] After the lithium battery loading and installation is completed, the end of the seesaw 45 away from the first plate 42 is subsequently separated from the placement rack 3, and the torsion spring between the seesaw 45 and the support rod 44 drives the seesaw 45 to reset, so that the height of the end of the seesaw 45 close to the first plate 42 is higher than the initial position of the end away from the first plate 42. During the reset process of the seesaw 45, the first plate 42 is driven to slide along the first groove 41 for reset, and during the reset process of the first plate 42, the first plate 42 keeps the discharge port of the upper hopper 4 blocked, and the remaining lithium batteries in the upper hopper 4 will not fall from the discharge port in the upper hopper 4. When the first plate 42 is reset, the sealing plate The torsion spring arranged between 43 and the upper hopper 4 drives the sealing plate 43 to reset. First, the sealing plate 43 is reset to block the discharge port of the upper hopper 4, and then the No. 1 plate 42 is reset to prevent the lithium batteries in the upper hopper 4 from leaking out before the sealing plate 43 blocks the upper hopper 4. At this time, one of the lithium batteries in the upper hopper 4 enters the space between the No. 1 plate 42 and the sealing plate 43 for the next loading and installation. The cooperation between the sealing plate 43 and the No. 1 plate 42 makes the loading and installation of the lithium battery smoother, thereby improving the loading and installation speed of the lithium battery, and further improving the detection efficiency of the lithium battery.

[0070] By setting the top of the placement rack 3 to be inclined, when the end of the seesaw 45 away from the No. 1 plate 42 contacts the top of the placement rack 3, along with the inclined surface of the top of the placement rack 3, the seesaw 45 can rotate more smoothly and gently with the support rod 44 as the fulcrum, driving the No. 1 plate 42 to descend, and when the end of the seesaw 45 away from the No. 1 plate 42 is located at the highest part of the top of the placement rack 3, the No. 1 plate 42 squeezes the lithium battery into the gap of the No. 1 shaft 34 to complete the loading and installation, avoiding the seesaw 45 driving the No. 1 plate 42 to contact the lithium battery too quickly, causing a collision and affecting the quality of the lithium battery, thereby improving the degree of protection of the lithium battery during the loading process.

[0071] Embodiment six:

[0072] On the basis of the fifth embodiment, a support column 5 is fixedly connected to the bottom of the placement rack 3, a sleeve 51 is provided on the conveyor belt 21, and the support column 5 is sleeved in the sleeve 51; the sleeve 51 is rotatably connected to the support column 5, and an arc block 52 is provided on the inner surface of the sleeve 51. A groove 53 is provided at the position of the support column 5 corresponding to the arc block 52, and a circular hole 54 is provided in the groove 53; a No. 1 block 55 is slidably connected in the circular hole 54, and a reset spring is provided between the No. 1 block 55 and the circular hole 54; one end of the arc block 52 is close to the inner wall of the groove 53, and the other end is away from the inner wall of the groove 53, and the arc block 52 is The number is two, and the arrangement is that the head end of the first arc block 52 is close to the tail end of the second arc block 52, and the first end and the tail end of the two arc blocks 52 form two corresponding arc block 52 gaps, and the initial position of the first block 55 is in the gap formed by the two arc blocks 52; when the support column 5 is stationary, the first block 55 extends out of the circular hole 54 and is located in the gap between the head end of the first arc block 52 and the tail end of the second arc block 52, so that the placement rack 3 is not affected by external forces, and the first block 55 limits the rotation of the support column 5 and the placement rack 3 through the limiting effect of the two arc blocks 52;

[0073] A second telescopic rod 25 is provided on the main body 2 between the appearance detection module 11 and the electrical detection module 12, and the output end of the second telescopic rod 25 faces the placement rack 3; the second telescopic rod 25 is connected to the network control platform 13, and the network control platform 13 controls the extension and retraction of the second telescopic rod 25;

[0074] The linkage plate 22 is arranged at intervals on the main body 2, and the second telescopic rod 25 is away from the linkage plate 22;

[0075] Specific work flow: After the placement rack 3 drives the lithium battery through the appearance inspection module 11, the unqualified lithium battery is detected and marked by the network control platform 13. When the placement rack 3 drives the unqualified lithium battery to move close to the bracket 23 located between the appearance inspection module 11 and the electrical inspection module 12, the network control platform 13 controls the first telescopic rod 24 to extend, squeeze the unqualified lithium battery off the placement rack 3 and drop it onto the conveyor belt 21;

[0076] Among the lithium batteries that have passed the appearance inspection, if the positive and negative electrodes are not placed in the specified direction, the appearance inspection module 11 will mark it after detecting it, and the conveyor belt 21 will drive the sleeve 51 to move, and the sleeve 51 will drive the placement rack 3 to approach the second telescopic rod 25 through the support column 5. When the lithium batteries whose positive and negative electrodes are not placed in the specified direction approach, the network control platform 13 will control the second telescopic rod 25 to extend. After the extended part of the second telescopic rod 25 contacts the placement rack 3, the sleeve 51 will continue to drive the placement rack 3 to move through the support column 5, and one side of the placement rack 3 is blocked by the second telescopic rod 25, so that the placement rack 3 is centered on the support column 5. The support column 5 rotates, and the placement frame 3 rotates to drive the support column 5 to rotate in the sleeve 51. The support column 5 rotates to make the arc block 52 move in the groove 53. The arc block 52 moves to contact the No. 1 block 55 in the groove 53, and the No. 1 block 55 is squeezed into the circular hole 54, so that the No. 1 block 55 is separated from the gap between the initial two arc blocks 52. After the No. 1 block 55 passes over one end of the arc block 52, the No. 1 block 55 is pushed by the reset spring provided in the circular hole 54 and moves along the surface of the arc block 52 to the gap between the next two arc blocks 52, until the No. 1 block 55 is stuck in the gap formed by the corresponding two arc blocks 52.

[0077] And cooperate with the No. 2 telescopic rod 25 to push the placement rack 3 to rotate, the placement rack 3 drives the support column 5 to rotate with the movement inertia, so that the No. 1 block 55 is easier to move from the gap of one arc block 52 to the gap of another arc block 52, so that the support column 5 and the placement rack 3 are locked and fixed after rotating 180 degrees, so that the lithium battery whose positive and negative poles are not placed in the specified direction can be adjusted to the direction of the positive and negative poles by rotating, so as to avoid that during electrical testing, the positive and negative poles of the lithium battery are not placed in the specified direction, which will affect the electrical testing of the lithium battery, and even cause a safety accident of lithium battery explosion due to the positive and negative poles. By automatically correcting the positive and negative poles of the lithium battery according to the regulations, the electrical testing efficiency of the lithium battery is improved, and then the testing efficiency of the testing equipment is improved, and the risk of detection errors is reduced;

[0078] During the rotation of the driving shaft 35 while contacting the linkage plate 22, since the linkage plate 22 is arranged at intervals on the main body 2, the driving shaft 35 rotates a specified angle when contacting the linkage plate 22, leaving enough time for the worker to observe the appearance of the lithium battery after the rotation angle, and then the driving shaft 35 contacts the linkage plate 22 again and rotates a specified angle, thereby avoiding the situation where the worker is inconvenient to observe the appearance of the lithium battery due to the continuous rotation of the lithium battery, reducing the number of unqualified lithium batteries in the appearance inspection module 11, and thus improving the inspection efficiency of the lithium battery;

[0079] And because the linkage plate 22 is far away from the second telescopic rod 25, the distribution range of the linkage plate 22 is between the upper hopper 4 and the second telescopic rod 25, so that when the lithium battery passes through this area, it rotates once at a specified interval, allowing workers and the appearance inspection module 11 to fully perform appearance inspection on the lithium battery, further improving the inspection efficiency of the lithium battery.

[0080] Embodiment seven:

[0081] On the basis of the sixth embodiment, the conveyor belt 21 is configured with an arc-shaped cross section, and the surface of the conveyor belt 21 is smoothed;

[0082] The main body 2 is evenly provided with collecting ports 6, and collecting boxes 61 are installed at positions corresponding to the collecting ports 6 on both sides of the main body 2; the collecting ports 6 and the collecting boxes 61 are evenly distributed between the appearance detection module 11 and the upper hopper 4, and between the appearance detection module 11 and the electrical detection module 12, and the electrical detection module 12 is away from the side of the appearance detection module 11;

[0083] Specific work flow: by setting the cross-section of the conveyor belt 21 to be arc-shaped and the surface of the conveyor belt 21 to be smooth, after the unqualified lithium batteries are removed and fall onto the conveyor belt 21, the unqualified lithium batteries move along the arc-shaped surface of the conveyor belt 21 to the edges on both sides, thereby increasing the movement effect of the unqualified lithium batteries, thereby accelerating the collection efficiency of the unqualified lithium batteries; after the unqualified lithium batteries reach the edges on both sides of the conveyor belt 21, the conveyor belt 21 continues to drive the lithium batteries to move until the lithium batteries pass through the collection port 6 and fall into the collection box 61, thereby realizing the collection and processing of unqualified lithium batteries and reducing the contact of workers with unqualified lithium batteries, because if the unqualified lithium batteries are bulging after overcharging detection, their own temperature may rise. At this time, if the workers are in contact with the lithium batteries in this state, dangerous accidents are likely to occur, thereby protecting the workers and reducing the risks brought by lithium battery detection;

[0084] Furthermore, the collecting port 6 and the collecting box 61 are evenly distributed between the appearance inspection module 11 and the upper hopper 4, between the appearance inspection module 11 and the electrical inspection module 12, and the electrical inspection module 12 is on the side away from the appearance inspection module 11, so that each collecting box 61 at a different position collects different unqualified lithium batteries, thereby realizing separate collection of unqualified lithium batteries, so that after collection, the unqualified lithium batteries can be separately processed according to the degree of unqualifiedness, thereby improving the convenience of using the detection equipment.
