Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to a device for conveying and identifying waste ternary cathode material battery packs. Background Technology

[0002] The waste battery cascade utilization system uses retired ternary lithium battery packs as the main raw material. After processes such as testing, screening, dismantling, and cascade utilization, battery packs that meet the cascade utilization standards are coded, packaged, and put into storage for sale; individual battery cells that do not meet the cascade utilization standards enter the waste battery comprehensive recycling system.

[0003] In the inspection and screening process, scrapped ternary cathode material battery packs are lifted to the workbench by a dedicated conveyor trolley via a loading machine. The sealing and damage of the batteries are checked, and the barcodes on the battery packs are first identified to obtain relevant battery information. Then, they are sent to the battery pack capacitor tester for testing. First, the barcode is scanned, and the CCD image identifies the battery model. Then, the capacitance, voltage, charge and discharge characteristics, and safety are tested. After that, the batteries are discharged in a discharge cabinet. Battery packs that meet the cascade utilization standards after discharge enter the cascade utilization process; those that cannot be cascaded are unpacked.

[0004] Currently, the inspection of the sealing and damage of batteries is generally done manually. Firstly, manual inspection is prone to omissions due to carelessness, and the human eye has limited vision, often failing to detect very minor or small damage. Secondly, manual inspection is inefficient. Thirdly, it is labor-intensive and easily causes fatigue, and the results are less accurate when people are tired. In addition, since battery packs have multiple sides, the position needs to be repeatedly adjusted to ensure comprehensive inspection, making the inspection process cumbersome and inefficient. Summary of the Invention

[0005] The present invention provides a waste ternary cathode material battery pack conveying and identification device, which can solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waste ternary cathode material battery pack conveying and identification device, which includes a feeding area, a detection area and a conveying area from left to right; wherein the feeding area is composed of a feeding mechanism, a straightening mechanism and a spacing mechanism, and the straightening mechanism and the spacing mechanism are arranged on the feeding mechanism from left to right. When the battery pack is fed through the feeding mechanism, it is straightened and spaced sequentially by the straightening mechanism and the spacing mechanism.

[0007] The testing area consists of a testing mechanism, a support mechanism, and a rotating pushing mechanism. The testing mechanism is located behind the right side of the support mechanism. The testing mechanism includes a testing bracket and a CCD camera. The testing bracket is a U-shaped structure with its opening facing the front. The two horizontal sections of the U-shaped structure are located on the upper and lower sides of the support mechanism, respectively.

The output shaft of the spacing cylinder is connected to the spacing plate.

[0013] As a preferred embodiment of the present invention, the supporting mechanism includes a base made of transparent material. The cross-section of the base along the feeding direction is a convex structure. The highest point of the base is slightly lower than the height of the conveyor belt. The middle protruding part of the base is uniformly provided with a first groove along the feeding direction. Two sets of lifting components are symmetrically slidably arranged in the first groove. The lower flat parts at the front and rear ends of the base are uniformly provided with a second groove. The lower end face of the lifting component away from the second groove is slidably arranged in the second groove.

[0014] As a preferred embodiment of the present invention, the lifting assembly includes a sliding plate, a horizontal plate, a support rod, a return spring, and lifting balls. The sliding plates correspond one-to-one with the grooves. The ends of the sliding plates away from the first groove are connected to the horizontal plate. The lower end face of the horizontal plate is provided with a support rod corresponding one-to-one with the second groove. The support rod is slidably connected to the second groove. A return spring is connected between the side of the support rod away from the sliding plate and the outer wall of the second groove. The return spring applies a pulling force to the support rod that always faces outward. The inner end of the sliding plate is an inclined surface that gradually slopes from top to bottom, and the top is uniformly rotatably provided with lifting balls. The highest point of the sliding plate is lower than the height of the protruding part of the base, and the highest point of the lifting balls is higher than the height of the protruding part of the base.

[0015] As a preferred embodiment of the present invention, the rotating pushing mechanism includes a driving fan, a lever, a rotating shaft, and a driving motor. The lower flat portions at both ends of the base are symmetrically provided with rotating shafts, which are rotatably connected to the base. A driving fan for pressing the horizontal plate is fixedly installed on the upper end of the rotating shaft at a position corresponding to the height of the horizontal plate. A lever for pushing the battery pack is detachably and rotatably installed on the rotating shaft above the driving fan. A pulley is fixedly installed on the portion of the rotating shaft that passes downward through the base. The pulleys are connected by belt drive. One of the rotating shafts is connected to the output shaft of the driving motor. The driving motor is fixedly installed on the support leg below the base. The driving fan has a fan-shaped structure, and its position in the circumferential direction of the rotating shaft corresponds to the lever.

[0016] As a preferred embodiment of the present invention, the lever includes a circular base and a long rod mounted on the circumferential surface of the circular base. The circular base has an annular structure, and multiple insert rods are evenly arranged circumferentially on the inner annular surface of the circular base via a spring telescopic rod. The outer circumferential surface of the rotating shaft is evenly provided with slots corresponding to the insert rods. The top surface of the rotating shaft is provided with a through groove corresponding to the insert rod along the circumferential direction. The lower end of the through groove is connected to the slot. A pressure rod is provided in the through groove for use with the insert rod. The top of each pressure rod is connected to a pressure plate. The position where the pressure rod and the insert rod cooperate is an inclined surface.

[0017] As a preferred embodiment of the present invention, the connecting mechanism includes an overlap plate, which is rotatably mounted on a base. An overlap spring is connected between the lower side of the overlap plate and the side of the base, and the overlap spring keeps the overlap plate facing downward. A roller is rotatably mounted on the lower side of the overlap plate away from the base, and the overlap plate is attached to the conveyor belt by the roller.

[0018] The present invention has the following beneficial effects: 1. The feeding mechanism, the detection mechanism, the supporting mechanism and the rotating pushing mechanism work together to realize the automated and efficient detection of the sealing and damage of the battery; at the same time, by setting two CCD cameras on the upper and lower sides of the supporting mechanism, and since the CCD cameras have a certain field of view, the effect of one-time all-round field of view detection of the battery is realized.

[0019] 2. The alignment mechanism of the present invention adjusts the placement of the battery pack, which is beneficial to improving the subsequent transportation and testing effects; the spacing mechanism blocks the battery pack to prevent the subsequent battery pack from being transported while the previous battery pack is being tested, thus affecting the testing work.

[0020] 3. The support mechanism of this application lifts the components to push the battery pack from the loading area to the testing area and to the testing position, thereby enabling the battery pack to roll and improve the conveying efficiency.

[0021] 4. The four sets of rotating pushing mechanisms of the present invention are driven by the same motor, thereby realizing that the rotating pushing mechanism pushes the battery pack in the feeding area to the detection position in the detection area, and at the same time pushes the battery pack in the detection position to the detection position, thereby achieving the purpose of continuous pushing and detection.

[0022] 5. This invention achieves the technical effect of lifting the battery pack off the base while pushing it, thereby reducing the pushing friction, through the cooperation of mechanisms such as the drive fan, lever, and lifting component. Attached Figure Description

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0034] See Figures 1-8 A waste ternary cathode material battery pack conveying and identification device includes a feeding area, a detection area and a conveying area from left to right. The feeding area consists of a feeding mechanism 1, a straightening mechanism 2 and a spacing mechanism 3. The straightening mechanism 2 and the spacing mechanism 3 are arranged on the feeding mechanism 1 from left to right. When the battery pack is fed by the feeding mechanism 1, it is straightened and spaced by the straightening mechanism 2 and the spacing mechanism 3 in sequence to ensure that the battery pack is conveyed neatly and that the front and rear intervals are large enough to avoid affecting the detection of the subsequent detection mechanism 4.

[0035] The testing area consists of a testing mechanism 4, a supporting mechanism 5, and a rotating pushing mechanism 6. The testing mechanism 4 is located behind the right side of the supporting mechanism 5. The testing mechanism 4 includes a testing bracket 41 and a CCD camera. The testing bracket 41 is a U-shaped structure with its opening facing the front end. The two horizontal sections of the U-shaped structure are located on the upper and lower sides of the supporting mechanism 5, respectively. The CCD camera is symmetrically arranged on the opposite side of the horizontal section of the U-shaped structure away from the vertical section. Four sets of rotating pushing mechanisms 6 are symmetrically arranged on the upper surface of the supporting mechanism 5. The testing area has two stations, a test station and a testing station, arranged from left to right. The two sets of rotating pushing mechanisms 6 on the left side correspond to the test station and are used to push the test battery packs on the test station to the testing station after the battery packs in front have been tested. The two sets of rotating pushing mechanisms 6 on the right side correspond to the testing station and are used to push the tested battery packs to the conveying area.

[0036] The conveying area consists of a conveying mechanism, which has the same structure as the feeding mechanism 1.

[0037] A connecting mechanism 7 is also installed between the feeding area and the testing area, as well as between the testing area and the conveying area.

[0038] See Figure 1 The feeding mechanism 1 includes a bracket 11, a rotating shaft 12, a support plate 13, a motor 14, a belt 15, and a conveyor belt 16. The bracket 11 has rotating shafts 12 symmetrically arranged on its upper side via mounting bases. A conveyor belt 16 connects the two symmetrical rotating shafts 12. One end of one rotating shaft 12 is connected to the output shaft of the motor 14 via the belt 15. During operation, the motor 14 is started, driving the rotating shaft 12 to rotate via the belt 15, which in turn drives the conveyor belt 16 to rotate, thus achieving the feeding of the battery pack from left to right. A support plate 13 is positioned on the bracket 11 between the left and right rotating shafts 12, located in the middle of the conveyor belt 16. This support plate 13 supports the battery pack and prevents the conveyor belt from collapsing. Rollers are evenly mounted on the support plate 13 from left to right, with the highest point of each roller slightly higher than the surface of the support plate 13 and in contact with the bottom side of the conveyor belt, improving the smoothness of battery pack feeding. Ball bearings are evenly distributed on the conveyor belt 16.

[0039] See Figure 1 The alignment mechanism 2 includes an alignment plate 21, an alignment cylinder 22, and a cylinder support 23. The cylinder support 23 is symmetrically arranged on the support 11, and the alignment cylinder 22 is arranged on the opposite side of the cylinder support 23. The output end of the alignment cylinder 22 is connected to the alignment plate 21. In actual operation, the spacing of the alignment plate 21 is adjusted by the alignment cylinder 22 according to the width of the battery pack, so as to facilitate the adjustment of the battery pack. The left end of the alignment plate 21 has a structure that gradually tilts outward and inward, and the opposite side of the alignment plate 21 has rollers with their axes arranged vertically.

[0040] See Figure 1 The spacing mechanism 3 includes a spacing bracket 31, a spacing cylinder 32, and a spacing plate 33. The spacing bracket 31 is installed at the rear right side of the bracket 11. The spacing bracket 31 is an inverted L-shaped structure. The spacing cylinder 32 is located on the lower side of the horizontal section of the L-shaped structure away from the vertical section. The output shaft of the spacing cylinder 32 is connected to the spacing plate 33. In specific operation, when the previous battery pack is transported to the support mechanism 5, the spacing cylinder 32 controls the spacing plate 33 to move downward, blocking the position of the next battery pack and preventing the next battery pack from being transported while the previous battery pack is being tested, thus affecting the testing work. When the previous battery pack is tested and begins to be transported backward, the spacing cylinder 32 controls the spacing plate 33 to move upward, so that the feeding mechanism 1 continues to transport the battery pack.

[0041] See Figure 2 , Figure 3 , Figure 4 and Figure 5 The supporting mechanism 5 includes a base 51 made of transparent material. The cross-section of the base 51 along the feeding direction is a convex structure. The highest point of the base 51 is slightly lower than the height of the conveyor belt, which facilitates the feeding mechanism 1 to transport the battery pack to the testing area. The middle protruding part of the base 51 is evenly provided with a groove 1 along the feeding direction. Two sets of lifting components 52 are symmetrically slidably arranged in the groove 1. The lower flat parts at the front and rear ends of the base 51 are evenly provided with a groove 2. The lower end face of the lifting component 52 away from the groove is slidably arranged in the groove 2.

[0042] The lifting assembly 52 includes a sliding plate 521, a horizontal plate 522, a support rod 523, a return spring 524, and lifting balls 525. Each sliding plate 521 corresponds to a groove. The end of each sliding plate 521 furthest from the first groove is connected to a horizontal plate 522. A support rod 523, corresponding to a second groove, is provided on the lower end face of the horizontal plate 522. The support rod 523 is slidably connected to the second groove. A return spring 524 is connected between the side of the support rod 523 furthest from the sliding plate 521 and the outer wall of the second groove. The return spring 524 applies a consistently outward pulling force to the support rod 523. The inner end of the sliding plate 521 is a gradually sloping surface from top to bottom, and the top is uniformly rotatably equipped with lifting balls 525. The highest point of the sliding plate 521 is lower than the height of the protruding part of the base 51, while the highest point of the lifting balls 525 is higher than the height of the protruding part of the base 51.

[0043] The purpose of making the lifting component 52 slidable in this invention is twofold: Firstly, when the rotating pushing mechanism 6 pushes the battery pack on the base 51 to the detection position, the presence of the lifting ball 525 and the inertial force may prevent it from stopping in time, potentially exceeding the optimal detection area. By sliding the lifting component 52 outward, the lifting ball 525 is disengaged from the battery pack, allowing the battery pack to fall onto the base 51, increasing friction and preventing the battery pack from moving forward, thus improving the detection effect. Secondly, the detection mechanism 4 in this application has CCD cameras on both the upper and lower sides of the support mechanism 5. To improve the clarity of the images, the lifting component 52 is moved below the battery pack.

[0044] In operation, the rotating pushing mechanism 6 is activated and presses the sliding plate 521. The sliding plate 521 slides in the groove towards the battery pack and gradually lifts the battery pack under the action of the lifting ball 525, reducing the friction of the battery pack and facilitating pushing. When the rotating pushing mechanism 6 stops pressing the sliding plate 521, the sliding plate 521 and the horizontal plate 522 are reset under the action of the return spring 524, and the lifting ball 525 stops lifting the battery pack. At this time, the battery pack falls on the upper surface of the base 51 and is no longer pushed.

[0045] The lower surface of the sliding plate 521 is uniformly fitted with ball bearings in contact with the bottom surface of the groove to reduce the friction between the sliding plate 521 and the groove.

[0046] See Figure 1 and Figure 2 The rotating pushing mechanism 6 includes a driving fan 61, a lever 62, a rotating pushing shaft 63, and a driving motor 64. The rotating pushing shaft 63 is symmetrically arranged on the lower flat parts at both ends of the base 51. The rotating pushing shaft 63 is rotatably connected to the base 51. The driving fan 61 for pressing the horizontal plate 522 is fixedly installed on the upper end of the rotating pushing shaft 63 at a position corresponding to the height of the horizontal plate 522. The lever 62 for pushing the battery pack is detachably and rotatably installed on the rotating pushing shaft 63 above the driving fan 61. A pulley is fixedly installed on the part of the rotating pushing shaft 63 that passes downward through the base 51. The pulleys are connected by belt drive. One of the rotating pushing shafts 63 is connected to the output shaft of the driving motor 64. The driving motor 64 is fixedly installed on the support leg below the base 51.

[0047] The driving fan surface 61 has a fan-shaped structure, and its position in the circumferential direction of the rotating push shaft 63 corresponds to the lever 62, so as to ensure that the lifting component 52 can play a supporting role throughout the pushing process and reduce the pushing resistance. The outer circumferential surface of the driving fan surface 61 is evenly distributed with rollers whose axis is parallel to the axis of the rotating push shaft 63, which is used to reduce the friction between the driving fan surface 61 and the horizontal plate 522.

[0048] In actual operation, once the battery pack at the detection position has been detected, the drive motor 64 is started, which drives all the rotating push shafts 63 to rotate via the belt. The rotation of each rotating push shaft 63 drives the drive fan surface 61 and the lever 62 above it to rotate. The drive fan surface 61 at both ends simultaneously presses the horizontal plate 522 to slide inward. When the lifting component 52 lifts the battery pack so that its bottom surface is away from the base 51, the lever 62 just rotates to be in contact with the battery pack. At this time, with the continuous rotation of the drive motor 64, the lever 62 can be used to move the battery pack forward while the lifting component 52 is lifting the battery pack. Since the four sets of rotating push mechanisms 6 are started at the same time, when the battery pack at the detection position is pushed to the conveying area, the battery pack at the detection position is also pushed to the detection position at the same time, so as to carry out the detection of the next battery pack.

[0049] See Figure 6 and Figure 7 The lever 62 includes a circular base 621 and a long rod 622 mounted on the circumferential surface of the circular base 621. The circular base 621 has an annular structure. Multiple insert rods 6211 are evenly arranged circumferentially on the inner arc surface of the circular base 621 via a spring telescopic rod. The outer circumferential surface of the rotating push shaft 63 is evenly provided with slots corresponding to the insert rods 6211. The top surface of the rotating push shaft 63 is provided with a through groove corresponding to the insert rods 6211 along the circumferential direction. The lower end of the through groove is connected to the slot. A pressure rod 6212 is provided in the through groove to cooperate with the insert rods 6211. The top ends of each pressure rod 6212 are connected to a pressure plate 6213. The position where the pressure rod 6212 and the insert rod 6211 cooperate is an inclined surface.

[0050] In practice, the operator places the lever 62 onto the rotating push shaft 63. When the insertion rod 6211 aligns with the slot, the insertion rod 6211 enters the slot under the action of the spring telescopic rod, thus fixing the lever 62 onto the rotating push shaft 63. When the angle of the lever 62 needs to be adjusted, the operator simply presses the pressure plate 6213. The pressure rod 6212 moves down and acts on the insertion rod 6211, pushing it out of the slot. At this time, the lever 62 disengages from the shaft. By rotating the lever 62 until it is adjusted to the appropriate angle, the pressure plate 6213 is released. By adjusting the angle of the lever 62, when the lifting assembly 52 lifts the battery pack so that its bottom surface is away from the base 51, the lever 62 rotates to be in contact with the battery pack.

[0051] See Figure 8The connecting mechanism 7 includes an overlap plate 71, which is rotatably mounted on the base 51. An overlap spring 72 is connected between the lower side of the overlap plate 71 and the side of the base 51. The overlap spring 72 keeps the overlap plate 71 facing downwards, thus enabling it to fit against the conveyor belt and facilitating the smooth transport of the battery pack from the loading area to the testing area and from the testing area to the transition transport area. A roller is rotatably mounted on the lower side of the overlap plate 71 away from the base 51. The overlap plate 71 fits against the conveyor belt through the roller, avoiding affecting the rotation effect of the conveyor belt. The end of the overlap plate 71 away from the base 51 has a pointed structure to facilitate fitting against the conveyor belt.

[0052] During operation: S1, feeding: Start motor 14, drive shaft 12 to rotate via belt 15, and then drive transmission belt 16 to rotate. According to the width of the battery pack, adjust the spacing of the aligning plate 21 via aligning cylinder 22, and then adjust the front and rear position of the battery pack. Guide the battery pack by the structure of the left end of the aligning plate 21 which is gradually tilted outward and inward, and the rollers with the axis of the aligning plate 21 evenly distributed on the opposite side along the vertical direction.

[0053] When a battery pack is transported to the support mechanism 5, the spacer plate 33 is moved down by the spacer cylinder 32 to block the position of the next battery pack, preventing the next battery pack from being transported while the previous battery pack is being tested, thus affecting the testing work; when the previous battery pack is tested and begins to be transported to the next battery pack, the spacer plate 33 is moved up by the spacer cylinder 32 to allow the feeding mechanism 1 to continue transporting the battery pack.

[0054] S2. Detection: The spacer plate 33 is moved upward by the spacer cylinder 32, causing the feeding mechanism 1 to transport the rightmost battery pack on the conveyor belt 16 to the detection position in the detection area. At this time, the drive motor 64 is started, driving all the rotating push shafts 63 to rotate via the belt. The rotation of each rotating push shaft 63 drives the lever 62 above it to rotate, thereby achieving the effect of pushing the battery pack on the detection position to the detection position via the lever 62. At this time, the lever 62 no longer pushes the battery pack, and controls the upper and lower CCD cameras to process the image of the battery pack. With the drive motor 64, the battery pack is moved upward. When lever 62 rotates to its initial position, the next battery pack is detected. During the process of lever 62 pushing the battery pack, since the driving fan 61 corresponds to the position of lever 62, while lever 62 pushes the battery pack, the driving fan 61 at both ends simultaneously presses the horizontal plate 522. The horizontal plate 522 drives the sliding plate 521 to slide towards the battery pack in the groove and gradually lifts the battery pack under the action of the lifting ball 525. This allows the lifting component 52 to lift the battery pack so that its bottom surface leaves the base 51, thereby realizing the rolling transport of the battery pack and improving the transport effect.

[0055] S3. Conveying: When the battery pack at the detection position has been detected, the rotating push mechanism 6 pushes the detected battery pack to the right conveying area. It should be noted that since the four sets of rotating push mechanisms 6 are started at the same time, when the battery pack at the detection position is pushed to the conveying area, the battery pack at the position to be detected also begins to be pushed to the detection position at the same time, so as to carry out the detection of the next battery pack.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
