Description

Technical Field

[0001] This utility model relates to the field of battery sorting technology, and in particular to an automatic sorting mechanism for defective products. Background Technology

[0002] In battery production, quality inspection is a crucial step, directly impacting battery performance, safety, and lifespan. Traditional battery sorting systems exhibit significant limitations in handling defective batteries after separating them from good ones. First, their handling accuracy is low, often resulting in misjudgments and misplacement. This not only affects production line efficiency but can also lead to defective products entering the market, harming consumer rights and corporate reputation. Second, traditional sorting systems are functionally limited, possessing only basic sorting capabilities and lacking necessary transfer capacity, making accurate collection and processing of batteries impossible. Furthermore, these systems often require a degree of manual intervention, increasing labor costs and reducing production efficiency. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this utility model provides an automatic sorting mechanism for defective products. It can solve the problems of low battery sorting efficiency and sorting misalignment.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] An automated sorting mechanism for defective products includes: a main conveyor line with a storage location for defective batteries; a transport vehicle frame with multiple transport vehicles for transporting defective batteries within the frame; a sorting vehicle mechanism including multiple sorting vehicles sliding on the transport vehicle frame for sorting and collecting defective batteries with different defects; a drive mechanism for transporting defective batteries to the storage location or the sorting vehicle mechanism; and a transfer mechanism for transferring the defective batteries sorted by the sorting vehicles to the transport vehicles.

[0006] By adopting the above solution, which utilizes a drive mechanism, a sorting cart mechanism, and a transfer mechanism, along with a precise control system, accurate grasping, sorting, and placement of defective batteries can be achieved. This significantly reduces misjudgments and misplaced sorting, improves sorting accuracy, and allows for flexible handling of sorted defective batteries; it also achieves automated operation, reducing manual intervention. Through the coordinated work of the drive mechanism, sorting cart mechanism, and transfer mechanism, the entire process from sorting to transportation of defective batteries can be completed, reducing labor costs and improving production efficiency.

[0007] Furthermore, the sorting vehicle includes: a chassis with a discharge hole in the center; a gripper assembly including two opposing grippers; and a gripping cylinder mounted on the chassis and drivenly connected to the gripper assembly.

[0008] By adopting the above solution and controlling the extension and retraction speed and force of the clamping cylinder, precise clamping and positioning of defective batteries can be achieved. This helps reduce errors and damage during the sorting process, improves sorting accuracy, and allows for direct unloading from the discharge port when unloading is required. The operation is simple and saves space.

[0009] Furthermore, the transfer mechanism includes: a longitudinal slide rail disposed on the frame of the transport vehicle; a transport support plate, one end of which is slidably disposed on the longitudinal slide rail; a support plate drive for driving the transport support plate to slide along the longitudinal slide rail; and a transport gripper fixed above the transport support plate.

[0010] By adopting the above solution, the longitudinal slide rails allow the transport support tray to move flexibly between the sorting cart and the transport vehicle without occupying additional lateral space. This design optimizes the spatial layout of the production line, making the entire sorting and transfer process more compact and efficient. The transport support tray slides along the longitudinal slide rails, achieving precise positioning and ensuring that the transport grippers accurately pick up defective batteries from the sorting cart and transfer them to the transport vehicle. This precise positioning capability reduces errors during transfer and improves the efficiency of the entire sorting system.

[0011] Furthermore, the transport gripper includes an integrally connected first gripping arm, a second gripping arm, a first sidewall, and a second sidewall, wherein the first gripping arm and the second gripping arm are disposed opposite to each other, and the first sidewall and the second sidewall are disposed opposite to each other.

[0012] By adopting the above solution, stronger support and stability can be provided when clamping defective batteries, reducing the risk of jaw deformation or damage caused by excessive clamping force or irregular battery shape.

[0013] Furthermore, the transport vehicle is equipped with a pallet, which is mounted on the top of the transport vehicle. The pallet is equipped with a support frame, which includes four spaced-apart foot supports, the inner walls of which form a rectangle.

[0014] By adopting the above solution, the tray becomes more stable when carrying defective batteries, reducing the risk of tray deformation or damage caused by bumps or collisions.

[0015] Furthermore, the transport gripper is cross-shaped, the gap between the foot supports in the support frame is cross-shaped, and the projected area of ​​the transport gripper on the horizontal plane is not greater than the projected area of ​​the gap between the foot supports in the support frame on the horizontal plane.

[0016] By adopting the above solution, the transport grippers can pass directly through the footrest gaps without additional adjustments or movements, thus simplifying the transfer process and improving overall transfer efficiency. Because collisions and obstructions during transfer are reduced, the wear and tear on the transport grippers and footrests is also correspondingly decreased. This helps extend the equipment's lifespan and reduce maintenance and replacement costs.

[0017] Furthermore, the gripper assembly is provided in multiple sets, the pallet is provided with multiple support frames, and the shipping support plate is provided with multiple shipping grippers. The number of gripper assemblies, support frames and shipping grippers is the same.

[0018] By adopting the above solution, multiple defective batteries can be transferred simultaneously. This greatly improves transfer efficiency, shortens the waiting time for batteries during sorting and transportation, and avoids waste or inefficient use caused by resource mismatch.

[0019] Furthermore, the driving mechanism includes a driving track, a robot arm sliding on the driving track, and a driving support frame. The main conveyor line is perpendicular to the driving track. The driving track is located on the driving support frame. There are two driving tracks and multiple robot arms, which are evenly distributed on the two driving tracks.

[0020] By adopting the above scheme, parallel transfer can be achieved, thereby significantly improving transfer efficiency. The two drive tracks can work simultaneously without interference, making the entire transfer process more efficient and smooth; it also offers a degree of scalability and flexibility. As production demands change, the number of robotic arms can be easily increased or decreased to adapt to different transfer requirements. Furthermore, the design of two drive tracks makes it easier for the system to integrate and collaborate with other production lines or equipment.

[0021] Furthermore, a sliding frame is provided between the robotic arm and the sliding rail. The sliding frame slides on the drive rail. A longitudinally arranged robotic arm slide rail is provided on the side of the sliding frame away from the drive support frame, and the robotic arm slides on the robotic arm slide rail.

[0022] By adopting the above solution, defective batteries can be transported between the main conveyor line and the sorting vehicle in the shortest possible time, thereby improving sorting efficiency.

[0023] Furthermore, the sorting vehicle mechanism includes a sorting vehicle slide rail, a sorting vehicle that moves along the sorting vehicle slide rail, and a drive unit that drives the sorting vehicle to slide. The sorting vehicle slide rail is located on the transport vehicle frame, and the sorting vehicle is located above the pallet of the transport vehicle.

[0024] By adopting the above solution, the drive unit can drive the sorting cart to slide along the sorting cart slide rail, so as to collect defective batteries with the same defects in the same sorting cart and achieve intelligent sorting effect.

[0025] In summary, the automatic sorting mechanism for defective products provided by this utility model has the following technical effects:

[0026] 1. By employing a drive mechanism and a transfer mechanism, coupled with a precise control system, accurate gripping, sorting, and placement of defective batteries can be achieved. This significantly reduces misjudgments and misplacement during sorting, ensuring sorting accuracy;

[0027] 2. Automated operation has been achieved, greatly reducing manual intervention. Through the coordinated work of the drive mechanism, sorting vehicle mechanism, and transfer mechanism, the entire process from sorting to transportation of defective batteries can be completed without human intervention, thereby reducing labor costs. Automated operation not only reduces manual intervention but also significantly improves production efficiency. The sorting mechanism can quickly and accurately complete the sorting and transfer of large quantities of defective batteries, enabling the production line to operate more smoothly.

[0028] 3. The multiple accommodating chambers and transport vehicles can accommodate more defective batteries, reducing waiting time and improving equipment utilization;

[0029] 4. It has good flexibility and can adapt to the sorting needs of defective batteries of different types and specifications. By adjusting the parameters and settings in the control system, it can easily cope with different production environments and sorting requirements. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0039] See Embodiment 1 of this utility model. Figures 1-4As shown, an automatic sorting mechanism for defective products is disclosed, including a drive mechanism 1, a main conveyor line 2, a transport vehicle frame 3, a sorting vehicle mechanism 5, and a transfer mechanism 6, for sorting defective batteries 7. In other embodiments, it includes, but is not limited to, sorting batteries 7. The drive mechanism 1 includes a drive rail 111 and a robotic arm 12 slidably mounted on the drive rail 111. Optionally, the robotic arm 12 includes at least one clamping position for holding the battery 7. In this embodiment 1, two clamping positions are provided. The main conveyor line 2 is perpendicular to the drive rail 111. A defective battery storage position 21 is provided on the main conveyor line 2. The transport vehicle frame 3 is adjacent to the main conveyor line 2. The transport vehicle frame 3 includes multiple accommodating cavities 31 arranged along the main conveyor line 2. A transport vehicle 4 with a tray 41 is provided in each accommodating cavity 31. The sorting vehicle mechanism 5 includes a sorting vehicle slide rail 51, a sorting vehicle 52 that moves along the sorting vehicle slide rail 51, and a drive component 53 that drives the sorting vehicle 52 to slide. The sorting vehicle slide rail 51 is provided on the transport vehicle frame 3. The sorting vehicle 52 is located above the tray 41 of the transport vehicle 4. The transfer mechanism 6 is used to transport the defective batteries 7 on the sorting vehicle 52 to the transport vehicle 4. By using the drive mechanism 1 and the transfer mechanism 6, in conjunction with a precise control system, the precise gripping, sorting, and placement of defective batteries 7 can be achieved. This significantly reduces misjudgments and missorting, improves sorting accuracy, and allows for flexible handling of defective batteries 7; it also automates operations and reduces manual intervention. Through the coordinated work of the drive mechanism 1, the sorting vehicle mechanism 5, and the transfer mechanism 6, the entire process from sorting to transporting defective batteries 7 can be completed, reducing labor costs and improving production efficiency.

[0040] Specifically, in this embodiment 1, the drive mechanism 1 further includes a drive support frame 11, which includes a support crossbar and at least two support longitudinal bars. The support longitudinal bars are supported below the support crossbar. Two drive tracks 111 are provided on the support crossbar of the drive support frame 11, and multiple robotic arms 12 are provided, evenly distributed across the two drive tracks 111. One support longitudinal bar is mounted on the transport vehicle frame 3, while the remaining support longitudinal bars are supported on a horizontal surface, allowing the support crossbar to span the main conveyor line 2 and the sorting vehicle mechanism 5. This facilitates the parallel transfer of batteries 7, significantly improving transfer efficiency. The two drive tracks 111 can operate simultaneously without interference, making the entire transfer process more efficient and smooth. Simultaneously, the number of robotic arms 12 can be increased or decreased on the drive tracks 111, with a minimum of one, thus providing scalability and flexibility. As production needs change, the number of robotic arms 12 can be easily increased or decreased to adapt to different transfer requirements. Meanwhile, the design of the two drive rails 111 also makes it easier for the system to be integrated and work collaboratively with other production lines or equipment.

[0041] In some embodiments, the sorting vehicle 52 includes a chassis 521, a gripper assembly 522, and a gripping cylinder 523. The chassis 521 has a discharge hole in its center. The gripper assembly 522 includes two opposing grippers. The gripping cylinder 523 is mounted on the chassis 521 and is drivenly connected to the gripper assembly 522. In this embodiment 1, the chassis 521 is a rectangular plate. The discharge hole is a hole through which the battery 7 can fall. The gripping cylinder 523 is fixed to the chassis 521 on both sides of the discharge hole so that the gripper assembly 522 can grip the battery 7 relative to each other. Preferably, each of the vehicle chassis is equipped with multiple sets of gripper assemblies 522. In this embodiment 1, the number of gripper assemblies 522 on the vehicle chassis is 6, thus capable of storing 6 batteries 7. By controlling the extension and retraction speed and force of the gripping cylinder 523, precise gripping and positioning of defective batteries 7 can be achieved. This helps reduce errors and damage during the sorting process, improves sorting accuracy, and allows for direct unloading from the unloading hole when unloading is required. The operation is simple and saves space.

[0042] In some embodiments, the transfer mechanism 6 includes a longitudinal slide rail 61, a transport support plate 62, a support plate drive 63, and transport grippers 64. The longitudinal slide rail 61 is disposed on the transport vehicle frame 3 between the sorting vehicle slide rail 51 and the transport vehicle 4. One end of the transport support plate 62 is slidably disposed on the longitudinal slide rail 61. The support plate drive 63 is used to drive the transport support plate 62 to slide along the longitudinal slide rail 61. The transport grippers 64 are fixed above the transport support plate 62. In this embodiment 1, two longitudinal slide rails 61 are provided, and each longitudinal beam slide rail is provided with one transport support plate 62. Each transport support plate 62 is provided with six sets of transport grippers 64, which are used to directly support and hold the six sets of batteries 7 falling from the discharge hole of the sorting vehicle 52. Preferably, the transport gripper 64 includes an integrally connected first gripping arm 641, a second gripping arm 642, a first sidewall 643, and a second sidewall 644. The first gripping arm 641 and the second gripping arm 642 are arranged opposite to each other, and the first sidewall 643 and the second sidewall 644 are arranged opposite to each other. The first gripping arm 641, the second gripping arm 642, the first sidewall 643, and the second sidewall 644 can clamp the four sides of the battery 7, improving the stability of the battery 7 during transport. It can provide stronger support and stability when clamping defective batteries 7. Preferably, the support plate drive 63 is a motor. Preferably, the transport support plate 62 is provided with a diagonal triangular rib below it to improve the support stability of the transport support plate 62.

[0043] In some embodiments, to reduce the time, space occupation, and operational steps of transferring the pallet 41 from the transfer mechanism 6 to the transport vehicle 4, the pallet 41 is adapted and improved. Specifically, the pallet 41 is mounted on the top of the transport vehicle 4, and a support frame 411 is provided on the pallet 41. The support frame 411 includes four spaced-apart foot supports 4111, the inner walls of which form a rectangle. Preferably, the number of support frames 411 is set to an integer multiple of 6, which can be used to store at least one number of batteries 7 carried on the transfer mechanism 6. In this embodiment 1, the number of support frames 411 is set to twelve, and six are grouped together, which can ensure that the spacing of the six support frames 411 in a group corresponds to six groups of transport grippers 64. Preferably, the transport grippers 64 are cross-shaped, the gaps between the foot supports 4111 in the support frame 411 are cross-shaped, and the projected area of ​​the transport grippers 64 on the horizontal plane is not greater than the projected area of ​​the gaps between the foot supports 4111 in the support frame 411 on the horizontal plane. With this configuration, the transport gripper 64 can pass directly through the gap between the foot supports 4111 without additional adjustment or movement steps, thus simplifying the transfer process and improving overall transfer efficiency. When the transport support plate 62 carries the transport gripper 64 upward along the longitudinal slide rail 61, the transport gripper 64 can pass through the gap between the foot supports 4111 and continue to rise. At this time, the transport gripper 64 can be used to receive and hold the battery 7 that is discharged from the discharge hole of the sorting vehicle 52. Subsequently, the transport support plate 62 carries the transport gripper 64 downward along the longitudinal slide rail 61. The transport gripper 64 passes through the gap between the foot supports 4111 and goes downward. The battery 7 on the transport gripper 64 cannot pass through the gap, so it will be directly supported on the foot support 4111. At this time, the battery 7 has been transferred to the transport vehicle 4, waiting for subsequent transfer and processing.

[0044] In other embodiments, multiple sets of gripper assemblies 522 are provided, and multiple support frames 411 are provided on the tray 41. The specific number of sets is not specifically limited, as long as multiple shipping grippers 64 are provided on the shipping support tray 62, and the number of gripper assemblies 522, support frames 411, and shipping grippers 64 are consistent. This greatly improves transfer efficiency, shortens the waiting time of batteries 7 during sorting and transportation, and avoids waste or inefficient use caused by resource mismatch.

[0045] In some implementations, a sliding frame 13 is also provided between the robotic arm 12 and the sliding rail. The sliding frame 13 slides on the drive rail 111, and a longitudinally arranged robotic arm slide rail 131 is provided on the side of the sliding frame 13 away from the drive support frame 11. The robotic arm 12 slides on the robotic arm slide rail 131. This allows for the lifting operation of the robotic arm 12, facilitating the transport of defective batteries 7 between the main conveyor line 2 and the sorting cart 52 in the shortest possible time, thereby improving sorting efficiency.

[0046] To prevent the machine from running empty without battery 7, a sensor is installed in the defective battery storage position 21 to detect whether there is a defective battery 7 in the defective battery storage position 21, so as to avoid the problem of the machine running empty.

[0047] It should be noted that all mechanisms in this system have a drive structure for operation, which includes, but is not limited to, servo motor drive, hydraulic drive, or pneumatic drive.

[0048] The operating steps of the automatic sorting mechanism of this utility model are as follows:

[0049] After the battery 7 undergoes appearance inspection using an image recognition algorithm, it is categorized as either good or defective. Good and defective batteries are placed below the support crossbar to ensure the robotic arm 12 can directly grasp them. The robotic arm 12 then picks up the good batteries and moves them onto the main conveyor line 2 for transport to the next workstation. The robotic arm 12 also picks up defective batteries and places them in the defective battery storage position 21 on the main conveyor line 2. Sensors detect whether battery 7 is present in the defective battery storage position 21. Therefore, the sorting cart 52 will only start operating when battery 7 is present in the defective battery storage position 21. When battery 7 is present in the defective battery storage position 21, the drive unit 53 drives the sorting cart 52 to move along the sorting cart slide rail 51 to below the robotic arm 12. The robotic arm 12 picks up the defective battery from the defective battery storage position 21 and places it on the sorting cart 52. The clamping cylinder 523 on the sorting cart 52 is activated to clamp the defective battery 7. The sorting cart 52 has six positions. The drive unit 53 moves the sorting cart 52 above the corresponding transport cart 4. The alignment method includes, but is not limited to, laser or sensor. The support plate drive 63 causes the transport gripper 64 to rise along the longitudinal slide rail 61 to the top of the pallet 41 of the transport vehicle 4 and the bottom of the battery 7 of the sorting vehicle 52. The gap in the middle of the pallet 41 allows the transport gripper 64 to pass through without interference. The clamping cylinder 523 of the sorting vehicle 52 causes the gripper assembly 522 to release and place the battery 7 on the transport gripper 64. The support plate drive 63 then causes the transport gripper 64 to descend and place the battery 7 on the foot support 4111 of the pallet 41. The transport vehicle 4 can transport 12 batteries 7 at a time. When the transport vehicle 4 is full, it is pulled out and transported to the defective product handling position, and the spare transport vehicle 4 next to it fills the gap. After the mechanism completes the action, it returns to the initial state.

[0050] Preferably, in some embodiments, an image recognition sensor can be added to the robotic arm 12 to classify defective batteries 7 into pre-welding defects and post-welding defects. According to the operation of the above mechanism, the robotic arm can be used to transport the batteries to different transport vehicles 4 for sorting, collection and transfer operations.

[0051] In summary, the automatic sorting mechanism for defective products provided by this utility model has the following technical effects:

[0052] 1. By employing a drive mechanism 1 and a transfer mechanism 6, in conjunction with a precise control system, accurate gripping, sorting, and placement of defective batteries 7 can be achieved. This significantly reduces misjudgments and misplaced sorting, ensuring sorting accuracy;

[0053] 2. Automated operation is achieved, greatly reducing manual intervention. Through the coordinated work of drive mechanism 1, sorting cart mechanism 5, and transfer mechanism 6, the entire process from sorting to transportation of defective batteries 7 can be completed without human intervention, thereby reducing labor costs. Automated operation not only reduces manual intervention but also significantly improves production efficiency. The sorting mechanism can quickly and accurately complete the sorting and transfer of large quantities of defective batteries 7, enabling the production line to operate more smoothly.

[0054] 3. The arrangement of multiple accommodating cavities 31 and transport vehicle 4 can accommodate more defective batteries 7, reducing waiting time and improving equipment utilization;

[0055] 4. It has good flexibility and can adapt to the sorting needs of different types and specifications of defective batteries. By adjusting the parameters and settings in the control system, it can easily cope with different production environments and sorting requirements.

[0056] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
