Description

Technical Field

[0001] This utility model relates to the field of lithium battery sorting technology, specifically to an automated lithium battery electrical sorting device. Background Technology

[0002] Currently, most mainstream automated lithium battery electrical sorting devices adopt a modular integrated design. They use vibratory feeders or conveyor belts to achieve orderly battery feeding, and combine high-precision testers to quickly collect key parameters such as voltage, internal resistance, and capacity of each battery. They rely on industrial computer systems to analyze data in real time and determine the grade. After grading, the batteries are pushed out by cylinders.

[0003] Patent CN222931299U discloses an automated lithium battery electrical sorting device, including a workbench. A screening machine and a support frame are mounted on opposite sides of the top of the workbench. A placement box is fixedly mounted on the upper side of the support frame. A dispersing component is located at the bottom of the placement box, and a cleaning mechanism for cleaning the batteries is located at the bottom of the dispersing component. The cleaning mechanism includes a transport component for transporting the batteries and two sets of cleaning components for wiping away dust from the batteries. This automated lithium battery electrical sorting device, by setting up the cleaning mechanism, can move the lithium batteries that have fallen onto the support plate downwards. During transport, both ends of the lithium batteries come into contact with a sponge, allowing the downward-moving lithium batteries to have their ends wiped clean, greatly reducing dust adhesion to the ends of the lithium batteries. This results in more accurate sorting results when the lithium batteries finally fall into the screening machine for testing.

[0004] The inventors have discovered at least the following problems in the prior art: The existing lithium battery electrical sorting device mentioned above, when the hopper transports the cylindrical lithium battery to the detection point, the battery bounces back because there is no buffer at the detection point. This causes the positive and negative electrodes at the detection point to be clamped and detected, resulting in the inability to detect and sort the battery. In addition, due to the different lengths of the batteries, the batteries may deviate when being guided by the wide guide hopper, requiring additional sorting during collection and thus limiting work efficiency.

[0005] Therefore, this solution provides an automated lithium battery electrical sorting device to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an automated lithium battery electrical sorting device to solve the problems in the prior art, such as the battery rebounding during feeding due to the lack of a buffer structure, which causes unstable electrode clamping and affects the detection accuracy, and the poor guiding effect of the discharge guide bucket on batteries of different lengths after sorting, which leads to deviation and requires secondary sorting.

[0007] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows: An automated lithium battery electrical sorting device includes a workbench, a feeding mechanism, and a detection and unloading mechanism. The feeding mechanism is installed above the workbench, and a buffer receiving mechanism is provided at the unloading port of the feeding mechanism. A base plate mechanism and a guiding mechanism are provided on both sides of the buffer receiving mechanism, with the guiding mechanism located above the base plate mechanism. The buffer receiving mechanism includes a receiving frame and two symmetrical semi-arc plates arranged inside the receiving frame. The detection and unloading mechanism includes a detection cylinder and two unloading cylinders. The detection cylinder is installed at one end of the receiving frame, and the unloading cylinders are located inside the receiving frame and below the semi-arc plates. The base plate mechanism includes base plates fixedly connected to both sides of the receiving frame. The guiding mechanism includes an unloading guide plate and inclined guide strips and parallel guide strips evenly distributed inside the unloading guide plate.

[0008] Preferably, a sliding groove is provided above the receiving frame, and grooves are provided at the four top corners of the receiving frame. The semi-arc plate and the feeding cylinder are both located inside the sliding groove, and a top plate is installed at the output end of the feeding cylinder.

[0009] Preferably, the two semi-circular plates are rotatably connected to each other on one side, a limiting shaft is fixedly connected to the bottom of the semi-circular plates, a spring is provided around the limiting shaft, a linkage plate is fixedly connected to the bottom of the limiting shaft, and the limiting shaft passes through the top plate.

[0010] Preferably, both ends of the semi-arc plate are provided with linkage racks, the top of the linkage racks are engaged with the linkage plate, one side of the linkage racks is meshed with a gear, one side of the gear is meshed with a connecting rack, and the connecting rack is located in the groove.

[0011] Preferably, a buffer slider is slidably connected above the base plate, a connecting rod is rotatably connected to one side of the buffer slider, the other end of the connecting rod is rotatably connected to the bottom of the feeding guide plate, and a spring is provided on one side of the buffer slider.

[0012] Preferably, one end of the feeding guide plate is fixedly connected to a connecting slider, the connecting slider is slidably connected to the groove and fixedly connected to the top of the connecting toothed rack, and the inclined guide strip and the parallel guide strip are fixedly connected to each other.

[0013] Preferably, a positive electrode and a negative electrode are installed on the inner side of the receiving frame, with the negative electrode installed at the output end of the detection cylinder.

[0014] The beneficial effects of this utility model are: This invention, by setting up a buffer receiving mechanism, utilizes the symmetrically arranged semi-circular plates and the bottom spring to mitigate the impact of the falling battery, prevent the battery from rebounding, and ensure that the battery remains stably in the detection position. This improves the clamping stability of the positive and negative electrodes on the battery, thereby ensuring the accuracy of the detection data and the reliability of the sorting.

[0015] This invention utilizes a transmission structure involving a linked rack and pinion, gears, and connecting racks to simultaneously lift one end of the feeding guide plate when the semi-arc plate moves. This achieves limited guidance of the battery, preventing it from rolling or shifting during the testing process, and further improving the stability and accuracy of the testing stage.

[0016] The material guiding mechanism of this utility model is equipped with inclined guide bars and parallel guide bars, which can effectively guide batteries of different lengths, so that they roll smoothly along a predetermined path, avoiding deviation caused by the different lengths of batteries during the feeding process, reducing subsequent sorting steps, and improving sorting efficiency and collection neatness.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] According to the appendix Figure 1 - Figure 5 As shown, this utility model provides an automated lithium battery electrical sorting device, including a workbench 1, a feeding mechanism 2 and a detection and unloading mechanism 3. The feeding mechanism 2 is installed above the workbench 1. A buffer receiving mechanism 4 is provided at the unloading port of the feeding mechanism 2. A base plate mechanism 5 and a guiding mechanism 6 are provided on both sides of the buffer receiving mechanism 4. The guiding mechanism 6 is located above the base plate mechanism 5. The buffer receiving mechanism 4 includes a receiving frame 41 and two symmetrical semi-arc plates 43 arranged inside the receiving frame 41; The detection and feeding mechanism 3 includes a detection cylinder 31 and two feeding cylinders 33. The detection cylinder 31 is installed at one end of the receiving frame 41, and the feeding cylinders 33 are located inside the receiving frame 41 and below the semi-arc plate 43. The base plate mechanism 5 includes a base plate 51 that is fixedly connected to both sides of the support frame 41; The material guiding mechanism 6 includes a feeding guide plate 61 and inclined guide bars 62 and parallel guide bars 63 evenly distributed on the inner side of the feeding guide plate 61; The feeding mechanism 2 is the feeding device in the sorting device in the prior art, and an intelligent device is also installed above the workbench 1 for sorting.

[0023] In a further embodiment, a slide groove 42 is provided above the receiving frame 41, and grooves 411 are provided at the four top corners of the receiving frame 41. The semi-arc plate 43 and the feeding cylinder 33 are both located inside the slide groove 42, and a top plate 331 is installed at the output end of the feeding cylinder 33.

[0024] In this embodiment, the groove 411 is used to limit the vertical movement range of one end of the feeding guide plate 61.

[0025] In a further embodiment, a connecting rod 431 is rotatably connected to one side of the two semi-arc plates 43 that are close to each other. A limiting shaft 44 is fixedly connected to the bottom of the semi-arc plates 43. A spring 45 is provided around the limiting shaft 44. A linkage plate 46 is fixedly connected to the bottom of the limiting shaft 44. The limiting shaft 44 passes through the top plate 331.

[0026] In this embodiment, when the feeding cylinder 33 operates, the top plate 331 moves upward, and the upper semi-arc plate 43 will move. However, since the other semi-arc plate 43 is not driven to move upward, the two sides of the connecting rod 431 will rotate, so that the two semi-arc plates 43 are at different heights and thus form an inclination for feeding and sorting.

[0027] In a further embodiment, both ends of the semi-arc plate 43 are provided with linkage racks 47, the top of the linkage racks 47 engages with the linkage plate 46, one side of the linkage racks 47 is meshed with a gear 48, one side of the gear 48 is meshed with a connecting rack 49, and the connecting rack 49 is located in the groove 411.

[0028] In this embodiment, the linkage rack 47 and the connecting rack 49 are both slidably connected inside the receiving frame 41, while the gear 48 is rotatably connected inside the receiving frame 41. Thus, when the semi-arc plate 43 is initially pressed down for buffering and when the battery is continuously above the semi-arc plate 43, the linkage plate 46 will move down, thereby driving the linkage rack 47 to move down. The top of the linkage rack 47 is not fixedly connected to the linkage plate 46 but only in contact. When not in contact, the connecting rack 49 will remain in its original position due to the weight of one end of the feeding guide plate 61.

[0029] In a further embodiment, a buffer slider 52 is slidably connected above the base plate 51, a connecting rod 53 is rotatably connected to one side of the buffer slider 52, and the other end of the connecting rod 53 is rotatably connected to the bottom of the feeding guide plate 61. A spring 54 is provided on one side of the buffer slider 52.

[0030] In this embodiment, the base plate 51 has a sliding groove at the buffer slider 52 so that it can slide. In addition, the connecting rod 53 can provide support for the feeding guide plate 61 when one end of the feeding guide plate 61 moves upward.

[0031] In a further embodiment, a connecting slider 611 is fixedly connected to one end of the feeding guide plate 61. The connecting slider 611 is slidably connected to the groove 411 and fixedly connected to the top end of the connecting rack 49. The inclined guide bar 62 and the parallel guide bar 63 are fixedly connected to each other.

[0032] In this embodiment, the cross-sections of the buffer slider 52 and the parallel guide bar 63 are both isosceles triangles made of rubber. The inclined guide bar 62 is inclined at twelve degrees to the inner wall of the feeding guide plate 61, which is used to guide the battery to roll close to the inner edge of the feeding guide plate 61 and cooperate with the parallel guide bar 63 to horizontally feed the battery.

[0033] In a further embodiment, a positive electrode 32 and a negative electrode 34 are installed on the inner side of the receiving frame 41, with the negative electrode 34 installed at the output end of the detection cylinder 31.

[0034] In this embodiment, the negative electrode 34 is brought close to the positive electrode 32 under the operation of the detection cylinder 31, thereby clamping the battery in the middle for detection. Then, after analysis by the intelligent device above the workbench 1, one of the feeding cylinders 33 is controlled to operate for sorting.

[0035] The working principle of this utility model is as follows: When the battery falls into the inner side of the receiving frame 41 through the feeding mechanism 2, it will be buffered by the semi-arc plate 43. At the same time, the transmission of the linkage rack 47, gear 48 and connecting rack 49 will cause one end of the unloading guide plate 61 to be lifted. This can not only buffer the battery through the spring 45 at the bottom of the semi-arc plate 43 to prevent the battery from rebounding, but also limit the two sides of the receiving frame 41 by lifting one end of the unloading guide plate 61 to prevent the battery from rolling. Then the detection cylinder 31 operates to make the negative electrode 34 clamp the battery for detection. After the test is completed, the external control equipment controls one of the feeding cylinders 33 in the receiving frame 41 to operate according to the data. This causes its output end to move upward with the semi-arc plate 43 and the battery above it. At this time, the other semi-arc plate 43 will not be able to move upward temporarily. Instead, it will move upward after being pulled by the connecting rod 431. This causes the two semi-arc plates 43 to tilt to one high and one low, so that the battery can roll to the inside of the feeding guide plate 61 for feeding. When the battery rolls to the inside of the feeding guide plate 61, it is first guided to the inner edge of the feeding guide plate 61 by the inclined guide bar 62, and then the parallel guide bar 63 makes the battery roll horizontally and stably. This can adapt to the feeding of different batteries and facilitate subsequent collection and sorting. Additionally, as the battery rolls within the parallel guide bar 63, the bottom of one end of the feed guide plate 61 is connected by a connecting rod 53, which causes the buffer slider 52 to compress the spring 54, thus providing further buffering.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
