[0002] To meet the battery capacity and output power requirements of mobile devices, it is often necessary to splice multiple batteries into a battery pack for use. Currently, the production process of splicing batteries into battery packs has a low degree of automation, and it is difficult to guarantee the splicing quality. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic battery pack splicing device that overcomes the above-mentioned defects and achieves high-quality automatic splicing of multiple batteries into a battery pack.

[0004] To achieve the above objectives, the solution of the present invention is: an automatic battery pack splicing device, including a base frame, and a rotating imaging component, a battery flipping mechanism, a battery feeding robot, an assembly conveying component, a material picking and dispensing component, a nickel sheet feeding component, a PTC feeding component, and a welding component are arranged on the base frame.

[0005] The rotating imaging component includes a rotating battery holder, a battery rotation drive mechanism, and a battery camera. The rotating battery holder allows the battery to be placed vertically. The battery rotation drive mechanism is connected to and drives the rotating battery holder to rotate horizontally while carrying the battery. The battery camera is used to capture images of the side of the battery.

[0006] The battery flipping mechanism includes a flipping battery holder and a battery flipping drive mechanism. The flipping battery holder is used to hold the battery, and the battery flipping drive mechanism is connected to and drives the flipping battery holder to flip the battery longitudinally.

[0007] The battery loading robot is used to place batteries into the rotating battery holder and to transfer batteries from the rotating battery holder to the flipping battery holder.

[0008] The assembly conveying assembly includes a conveying mechanism and an assembly battery holder. The conveying mechanism conveys the assembly battery holder, which is used to hold multiple batteries side by side. The material picking and dispensing assembly, the nickel sheet feeding assembly, the PTC feeding assembly, and the welding assembly are arranged sequentially along the conveying path of the assembly battery holder.

[0009] The material handling and dispensing assembly includes a battery transfer robot, a glue gun, and a material handling and dispensing drive mechanism for driving the displacement of the battery transfer robot and the glue gun. The battery transfer robot is used to pick up the batteries on the flipped battery holder and place them on the assembled battery holder. The glue gun is used to dispense and bond multiple batteries on the assembled battery holder.

[0010] The nickel sheet feeding assembly is used to place nickel sheets at both ends of multiple batteries on the assembled battery holder;

[0011] The PTC feeding assembly is used to place PTCs at both ends of multiple batteries on the assembled battery holder;

[0012] The welding assembly is used to move to the ends of multiple batteries on the battery assembly base for welding.

[0013] Furthermore, the battery assembly holder includes a battery assembly holder fixing plate and a battery assembly holder flip plate. The upper surface of the battery assembly holder fixing plate is provided with a plurality of second battery positioning grooves that fit the side contour of the battery. The battery assembly holder fixing plate is pivotally connected to a battery assembly holder flip plate at both ends of the extension direction of the second battery positioning grooves. Each battery assembly holder flip plate is provided with a nickel sheet positioning groove for inserting nickel sheets and a PTC positioning groove for inserting PTCs, so that the nickel sheets placed in the nickel sheet positioning grooves and the PTCs placed in the PTC positioning grooves are flipped up and stand up with the battery assembly holder flip plate, fitting against the front and rear ends of the plurality of batteries in the second battery positioning grooves.

[0014] Furthermore, the material picking and dispensing assembly also includes a layout gripper, and the material picking and dispensing driving mechanism drives the layout gripper to move. The layout gripper is used to simultaneously axially clamp multiple batteries in multiple second battery positioning slots for positioning.

[0015] Furthermore, the nickel sheet feeding assembly includes a nickel sheet vibratory feeder, a nickel sheet positioning camera, a nickel sheet suction seat transfer mechanism, and a nickel sheet suction seat. The nickel sheet vibratory feeder is used to vibrate and disperse multiple nickel sheets thereon. The nickel sheet positioning camera illuminates the nickel sheet vibratory feeder to position a nickel sheet on the nickel sheet vibratory feeder and is communicatively connected to the nickel sheet suction seat transfer mechanism. The nickel sheet suction seat picks up or releases the nickel sheet. The nickel sheet suction seat transfer mechanism is used to connect to and drive the nickel sheet suction seat to move between the nickel sheet positioned by the nickel sheet positioning camera and each nickel sheet positioning slot.

[0016] Furthermore, the PTC feeding assembly includes a PTC feeding device, a PTC positioning camera, and a PTC transfer robot.

[0017] The PTC feeding device includes a material basket, a material hook, a material tray guide rail, a material hook drive mechanism, and a material basket drive mechanism. The material basket has a material tray pick-up and drop-off port on its side. Multiple material trays are arranged longitudinally and horizontally inside the material basket. Multiple PTCs are placed on top of each material tray. The material hook and the material tray guide rail are fixedly positioned longitudinally outside the material tray pick-up and drop-off port. The material hook drive mechanism is connected to and drives the material hook to move horizontally to move closer to or away from the material tray pick-up and drop-off port. Each material tray has a hook hole. When the material hook moves to the hook hole, the material basket drive mechanism drives the material basket to rise and fall, so that the material hook can hook and pull out the material tray. The material tray guide rail extends along the movement direction of the material hook to receive and guide the pulled-out material tray.

[0018] The PTC positioning camera is positioned above the pulled-out tray to capture images, thereby locating a PTC on the pulled-out tray. The PTC transfer robot is used to pick up the PTC located by the PTC positioning camera and place it into the PTC positioning slot.

[0019] Furthermore, the welding assembly includes a welding head and a welding head driving mechanism. The battery assembly holder is horizontally and rotatably mounted on the turntable. The two battery assembly holder flaps on the battery assembly holder have welding head clearance holes at the ends of the batteries on the corresponding battery assembly holder fixing plates. The welding head driving mechanism is connected to and drives the welding head to insert into or retract from each welding head clearance hole.

[0020] Furthermore, it also includes a feeding assembly and a battery material tray for vertically inserting multiple batteries. The feeding assembly includes a material tray supply conveyor belt, a material tray recycling conveyor belt, and a material tray lifting and transfer mechanism. The material tray supply conveyor belt conveys the battery material tray below the battery loading robot. The material tray recycling conveyor belt is located below the material tray supply conveyor belt and conveys the battery material tray in a direction away from the battery loading robot. The material tray lifting and transfer mechanism is located below the battery loading robot, receives the battery material tray sent out by the material tray supply conveyor belt, and lowers the received battery material tray to the starting end of the material tray recycling conveyor belt. The battery loading robot is used to clamp the batteries in the battery material tray into the rotating battery holder.

[0021] Furthermore, the flip battery holder includes a flip battery holder fixed plate and a flip battery holder movable plate. The flip battery holder fixed plate is provided with a plurality of first battery positioning grooves arranged side by side to fit the side contour of the battery. The flip battery holder movable plate presses against or moves away from each of the first battery positioning grooves.

[0022] Furthermore, the conveying mechanism is a turntable fixed above the base frame, and multiple battery mounting bases are installed in a circumferential array on the turntable.

[0023] Furthermore, the base frame is also equipped with a discharge robot and a discharge conveyor belt. The discharge robot is used to transfer the batteries on the battery assembly base to the discharge conveyor belt.

[0024] After adopting the above solution, the beneficial effects of the present invention are as follows:

[0025] (1) The battery side image is captured by the battery camera to obtain the actual orientation of the battery. The rotating battery holder is driven to rotate horizontally by the battery rotation drive mechanism, so that each battery pre-welded into a battery pack faces the predetermined direction before welding, so as to avoid the identification code of each battery side wall being blocked after welding, so as to facilitate subsequent traceability.

[0026] (2) The battery assembly holder is conveyed by the conveying mechanism. The battery assembly holder is used to place multiple batteries side by side horizontally. The material picking and dispensing component, nickel sheet feeding component, PTC feeding component and welding component are arranged sequentially along the conveying path of the battery assembly holder. In this way, the battery on the battery assembly holder is dispensed with glue, nickel sheet and PTC are placed at the end of the battery, and welding is completed. This achieves high-quality automatic splicing of multiple batteries into a battery pack. Attached Figure Description

Detailed Implementation

[0043] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] This invention provides an automatic battery pack splicing device, such as... Figure 1-15 As shown, the focus here is on combining... Figure 1 , Figure 4 , Figure 5 As shown, it includes a base frame 1 and a feeding assembly 10. The base frame 1 is equipped with a rotating photography assembly 2, a battery flipping mechanism 3, a battery feeding robot 4, an assembly conveying assembly 5, a material picking and dispensing assembly 6, a nickel sheet feeding assembly 7, a PTC feeding assembly 8, and a welding assembly 9.

[0045] Key points combined Figure 2As shown, the feeding assembly 10 is used to convey the battery material tray 59. The battery material tray 59 has multiple battery insertion slots arranged in an array for vertically inserting multiple batteries 16. The feeding assembly 10 includes a material tray supply conveyor belt 46, a material tray recycling conveyor belt 47, and a material tray lifting and transfer mechanism 48. The material tray supply conveyor belt 46 conveys the battery material tray 59 below the battery loading robot 4. The material tray supply conveyor belt 46 is driven by a motor. The material tray recycling conveyor belt 47 is located below the material tray supply conveyor belt 46 and conveys the battery material tray 59 in a direction away from the battery loading robot 4. The material recycling conveyor belt 47 consists of multiple unpowered, freely rolling rollers, and the height of the rollers gradually decreases from the side closer to the battery loading robot 4 to the side away from the battery loading robot 4, so that the battery material tray 59 is conveyed along the material recycling conveyor belt 47 by gravity. The material tray lifting and transfer mechanism 48 is located below the battery loading robot 4 and receives the material tray 59. The battery material tray 59 fed by the supply conveyor belt 46 is lowered to the starting end of the material tray recycling conveyor belt 47. In this embodiment, the material tray lifting and transfer mechanism 48 includes a material tray lifting drive mechanism 54 and a material tray lifting platform 55. The material tray lifting drive mechanism 54 drives the material tray lifting platform 55 to rise and fall. The material tray lifting platform 55 carries the battery material tray 59. Thus, during operation, the battery material tray 59 can be transported by the supply conveyor belt 46. The tray 59 is conveyed to the material tray lifting platform 55 below the battery loading robot 4. Then, the battery 16 carried on the battery material tray 59 can be removed by the battery loading robot 4 for loading. After all the batteries on the battery material tray 59 are removed, the battery material tray 59 is transferred to the material tray recycling conveyor belt 47 for material tray recycling. In order to prevent the battery 16 from getting stuck in the battery insertion slot of the battery material tray 59, the material tray lifting platform 55 is also equipped with a patting cylinder 56 to pat the battery material tray 59.

[0046] Key points combined Figure 4As shown, the rotating imaging assembly 2 includes a rotating battery holder 13, a battery rotation drive mechanism 14, and a battery camera 15. The rotating battery holder 13 provides a vertical place for the battery 16. The rotating battery holder 13 is magnetic to attract the vertically placed battery 16, preventing the battery 16 from tipping over due to its high center of gravity. The battery rotation drive mechanism 14 connects to and drives the rotating battery holder 13 to rotate horizontally while carrying the battery 16. The battery camera 15 is used to capture side images of the battery 16. The battery camera 15 is communicatively connected to the battery rotation drive mechanism 14. Through the images captured by the battery camera 15, the actual orientation of the battery 16 on the rotating battery holder 13 is obtained. Then, the orientation of the battery 16 is adjusted by the rotating battery holder 13, so that each battery 16 pre-welded into a battery pack faces a predetermined direction before welding, avoiding the identification code on the side wall of each battery 16 being obscured after welding, thus facilitating subsequent traceability. Specifically in this embodiment, four rotating battery holders 13 are arranged in a horizontal array, and each rotating battery holder 13 is provided with a battery rotation drive mechanism 14 to simultaneously rotate and adjust the orientation of four batteries 16. The number of rotating battery holders 13 and rotating battery drive mechanisms 14 is not specifically limited, and can be specifically set according to the actual number of batteries on a battery pack that needs to be welded.

[0047] Key points combined Figure 5 As shown, the battery flipping mechanism 3 includes a flipping battery holder 17 and a battery flipping drive mechanism 18. The flipping battery holder 17 is used to hold the battery 16, and the battery flipping drive mechanism 18 is connected to and drives the flipping battery holder 17 to flip the battery 16 longitudinally. Specifically, the flipping battery holder 17 includes a flipping battery holder fixing plate 49 and a flipping battery holder movable plate 50. The flipping battery holder fixing plate 49 has a plurality of first battery positioning grooves arranged side by side that fit the side contour of the battery 16. In this embodiment, four first battery positioning grooves 15 are correspondingly provided. The flipping battery holder movable plate 50 is pneumatically pressed towards or away from each of the first battery positioning grooves to fix the battery 16 in each of the first battery positioning grooves. Then, the battery 16, which has been adjusted at the angle on the rotating imaging component 2, is transferred into the battery positioning groove 15 of the battery flipping mechanism 3. Then, the battery flipping mechanism 3 flips the battery 16 by ninety degrees, so that the battery 16 changes from a vertical state to a horizontal inverted state, so as to facilitate subsequent welding.

[0048] Key points combined Figure 3As shown, the battery loading robot 4 is used to clamp the battery 16 in the battery material tray 59 onto the rotating battery holder 13, place the battery 16 onto the rotating battery holder 13, and transfer the battery 16 from the rotating battery holder 13 to the flipping battery holder 17. The battery loading robot 4 can be any existing multi-axis linkage robot capable of performing the above functions. Specifically, in this embodiment, the battery loading robot 4 includes a loading robot gripper 57 and a loading robot gripper drive mechanism 58. The loading robot gripper 57 can open and close to clamp or release the vertically placed battery 16. The loading robot gripper drive mechanism 58 drives the loading robot gripper 57 to clamp the battery 16 on the bottom. The loading robot gripper 57 moves forward, backward, left, right, and lifts above the frame 1. When the loading robot gripper 57 moves above the battery material tray 59, it can pick up the batteries on the battery material tray 59. When the loading robot gripper 57 moves above the rotating battery holder 13, it places the batteries 16 it has picked up onto the rotating battery holder 13. After the rotating battery holder 13 has adjusted the orientation of the batteries 16, the loading robot gripper 57 picks up the batteries 16 from the rotating battery holder 13 and transfers them into the battery positioning groove 15 of the flip battery holder 17. The loading robot gripper 57 can be configured to pick up one or more batteries 16 at the same time, without specific limitation.

[0049] Key points combined Figure 7 As shown, the assembly conveying component 5 includes a conveying mechanism and an assembly battery holder 19. The conveying mechanism conveys the assembly battery holder 19, which accommodates multiple batteries 16 arranged side-by-side horizontally. The material handling and dispensing component 6, the nickel sheet feeding component 7, the PTC feeding component 8, and the welding component 9 are arranged sequentially along the conveying path of the assembly battery holder 19. The path along which the conveying mechanism moves the assembly battery holder 19 is not specifically limited. In this embodiment, the conveying mechanism is a turntable 52 fixed above the base frame 1. Multiple assembly battery holders 19 are mounted in a circumferential array on the turntable 52. By rotating the turntable 52, the assembly battery holders 19 are cyclically conveyed between various workstations. (Further details are needed for a complete translation.) Figure 8 , Figure 9 , Figure 14As shown, the battery assembly holder 19 includes a battery assembly holder fixing plate 24 and a battery assembly holder flip plate 25. The upper surface of the battery assembly holder fixing plate 24 has multiple second battery positioning grooves 26 arranged side-by-side to fit the side contours of the batteries 16. In this embodiment, three batteries 16 are to be welded into a battery pack, therefore, the battery assembly holder fixing plate 24 has three second battery positioning grooves 26. A battery assembly holder flip plate 25 is pivotally connected to the front and rear ends of the battery assembly holder fixing plate 24 at the extending directions of the second battery positioning grooves 26. Specifically, each of the two battery assembly holder flip plates 25 is fixed to a laterally extending flip plate pivot 60. Rotation of the flip plate pivot 60 causes the battery assembly holder flip plate 25 to flip to a horizontal or upright position. Each flip plate pivot 60 has a diameter... A drive arm 61 protrudes outwards, and by pushing the drive arm 61, the flip plate shaft 60 is driven to rotate the battery assembly base flip plate 25. Each battery assembly base flip plate 25 is provided with a nickel sheet positioning groove 27 for nickel sheets and a PTC positioning groove 28 for PTCs. The nickel sheets placed in the nickel sheet positioning groove 27 and the PTCs placed in the PTC positioning groove 28 are turned up and stand upright as the battery assembly base flip plate 25 is rotated, and are attached to the front and rear ends of the multiple batteries 16 in the second battery positioning groove 26. The bottom of the nickel sheet positioning groove 27 and the PTC positioning groove 28 is provided with magnets or vacuum holes to attract the nickel sheets and PTCs and prevent the nickel sheets and PTCs from falling out of the nickel sheet positioning groove 27 and the PTC positioning groove 28 when the battery assembly base flip plate 25 is turned up.

[0050] Key points combined Figure 6As shown, the material handling and dispensing assembly 6 includes a battery transfer robot 21, a glue gun 22, and a material handling and dispensing drive mechanism 23 that drives the displacement of the battery transfer robot 21 and the glue gun 22. The battery transfer robot 21 is used to pick up the batteries 16 on the flipped battery holder 17 and place them on the assembly battery holder 19. The glue gun 22 is used to dispense and bond multiple batteries 16 on the assembly battery holder 19. The material handling and dispensing assembly 6 also includes a layout gripper 29. The material handling and dispensing drive mechanism 23 drives the layout gripper 29 to move. The layout gripper 29 is used to simultaneously axially clamp multiple batteries 16 in multiple second battery positioning slots 26 for positioning. The material handling and dispensing drive mechanism 23 can be any existing multi-axis linkage mechanism that can achieve the above functions. In this embodiment, the robotic arm specifically includes a mounting base 62 and a main body 63 for picking up and dispensing adhesive. The battery transfer robotic arm 21, glue gun 22, and layout gripper 29 are all mounted on the mounting base 62. The main body 63 drives the mounting base 62 to move forward, backward, left, right, and up and down above the base frame 1. The battery transfer robotic arm 21 pneumatically picks up the batteries 16 that are horizontally placed upside down in each of the first battery positioning slots 15. When it moves to the battery assembly seat 19, it pneumatically releases each battery 16, so that each battery 16 falls into the corresponding second battery positioning slot 26. The glue gun 22 is set with the glue outlet facing downward so that it can move above each battery 16 in each of the second battery positioning slots 26 to dispense adhesive.

The material basket 36 has a material tray pick-and-place port 41 on its side. Multiple material trays 42 are arranged vertically and horizontally inside the material basket 36, and multiple materials are placed on top of each material tray 42. In the PTC (Plate Tray Controlled Toilet), the material hook 37 and the tray guide rail 38 are longitudinally fixed outside the tray pick-up / placement opening 41. The material hook drive mechanism 39 is connected to and drives the material hook 37 to move horizontally closer to or further away from the tray pick-up / placement opening 41. Each tray 42 is provided with a hook hole 43, so that when the material hook 37 moves to the hook hole 43, the tray drive mechanism 40 drives the tray 36 to rise and fall, allowing the material hook 37 to hook and pull out the tray 42.
