Description

Technical Field

[0001] This utility model relates to the field of battery connector feeding technology, and in particular to a battery connector feeding and positioning mechanism. Background Technology

[0002] In the automated assembly process of power batteries and energy storage battery modules, the robotic loading of battery connectors is a critical node affecting production line efficiency and finished product quality. The assembly accuracy of the connectors directly affects the conductivity, structural stability, and safety of the battery module. However, existing technologies have significant shortcomings in this area. Currently, the industry commonly uses robots to directly pick up the connectors. Due to the lack of effective pre-positioning methods, the connectors are prone to positional deviations, resulting in low pick-up success rates, slow loading cycles, and potential defects in subsequent welding or assembly processes. This makes the loading stage a bottleneck restricting the overall production line's capacity and yield improvement. Therefore, developing a technical solution that can accurately and reliably position battery connectors before robot pickup has become a core need urgently requiring solutions in the industry. Utility Model Content

[0003] The purpose of this invention is to provide a battery connector feeding and positioning mechanism that can position the battery connector before the robot picks it up.

[0004] The technical solution of this utility model:

[0005] A battery connector feeding and positioning mechanism includes an installation cabinet, a feeding mechanism is provided inside the installation cabinet, a four-axis feeding gripper is provided on the top of the installation cabinet, and a secondary positioning mechanism is provided on the top of the installation cabinet behind the four-axis feeding gripper.

[0006] The secondary positioning mechanism includes a third mounting plate fixed to the top of the mounting cabinet. An L-shaped plate is fixed to the third mounting plate, and multiple placement platforms are provided on the top horizontal plate of the L-shaped plate. Two second linear guides are also fixed to the third mounting plate, and the sliders of the two second linear guides are connected to a first moving plate, which is driven to move by a first cylinder. A third linear guide is fixed to the first moving plate, and the number of sliders of the third linear guide is the same as the number of placement platforms. A first positioning block is fixed to the slider of the third linear guide, and the upper end of the first positioning block penetrates the L-shaped plate and is located beside the placement platform. A first buffer plate is fixed to the first moving plate beside the first positioning block, and the first positioning block is connected to the first buffer plate via a second spring.

[0007] Furthermore, a second movable plate is provided on the top of the mounting cabinet behind the third mounting plate. The second movable plate is connected to the mounting cabinet via a slider of a fourth linear guide rail. The second movable plate is driven to move back and forth by a second cylinder. A plurality of second positioning blocks are fixed to the rear of the second movable plate. The number of the second positioning blocks is the same as the number of the placement platforms.

[0008] Furthermore, the feeding mechanism includes two sets of feeding conveyor lines installed inside the mounting cabinet. A feeding lifting arm is installed above the feeding conveyor lines, and the feeding lifting arm is driven to rise and fall by a lifting component. A rodless cylinder is fixed to the top of the mounting cabinet, and a frame plate is fixed to the top of the slider of the rodless cylinder. First suction cups are fixed to the four corners of the frame plate. An eighth linear guide rail is fixed to the top of the mounting cabinet in front of the rodless cylinder, and the slider of the eighth linear guide rail is connected to the frame plate.

[0009] Furthermore, the lifting assembly includes a first mounting plate disposed on the rear side of the feeding conveyor line, the rear part of the first mounting plate being fixedly connected to the inner top surface of the mounting cabinet via a first triangular plate; first linear guide rails are fixed on both the left and right sides of the front part of the first mounting plate, and the sliders of the first linear guide rails are fixed to the bottom of the feeding lifting arm via a second triangular plate; a trapezoidal lead screw is connected to the middle front part of the first mounting plate via a bearing seat, the trapezoidal lead screw being driven to rotate by a first motor; the slider of the trapezoidal lead screw is fixedly connected to the rear part of the feeding lifting arm.

[0010] Furthermore, the four-axis loading gripper includes a four-axis robot, the execution end of which is fixed with a second mounting plate, and the bottom of the second mounting plate is fixed with multiple sets of adsorption components, the adsorption components including two second suction cups connected to the second mounting plate via a first fixing frame; a vision camera is fixed to the second mounting plate via the second fixing frame; and a vision light source is fixed to the second mounting plate via a third fixing frame.

[0011] Furthermore, an NG frame and a buffer platform are also fixed to the top of the mounting cabinet.

[0012] The beneficial effects of this utility model are:

[0013] (1) The first suction cup is used to adsorb the tray. After all the battery connecting pieces in the tray are loaded, the frame tray is moved by the rodless cylinder, thereby moving the tray to the other side for unloading. The top of the mounting cabinet is fixed with an eighth linear guide rail in front of the rodless cylinder. The slider of the eighth linear guide rail is connected to the frame tray. The eighth linear guide rail can assist the frame tray in moving, making the frame tray move stably.

[0014] (2) The trapezoidal screw is driven to rotate by the first motor, thereby driving the loading lifting arm to rise and fall, and then driving the tray on the loading lifting arm to rise and fall. During the lifting process, the first linear guide rail can assist the loading lifting arm to move, so that the loading lifting arm can rise and fall stably.

[0015] (3) The second suction cup is used to adsorb the battery connector; the vision camera is used to take pictures to detect whether the battery connector is reversed or shifted, etc.; the vision light source is used to supplement light and assist the vision camera in taking pictures and detecting.

[0016] (4) After the four-axis loading gripper places the battery connecting piece onto the placement platform, the first cylinder drives the first moving plate to move, thereby moving the first positioning block and pushing the battery connecting piece into the placement platform, thus positioning the lateral position of the battery connecting piece. During this process, the second linear guide rail assists the first moving plate in moving; when the first positioning block pushes the battery connecting piece into the placement platform so that the battery connecting piece abuts against the inner wall of the placement platform, the first moving plate moves in the opposite direction due to the reaction force, thereby squeezing the second spring and the first buffer plate, playing a buffering role; during this process, the third linear guide rail assists the first positioning block in moving.

[0017] (5) The second moving plate is driven to move backward by the second cylinder, thereby driving the second positioning block to move the battery connecting piece into the placement platform, thus positioning the longitudinal position of the battery connecting piece. During this process, the fourth linear guide rail assists the movement of the second positioning block.

[0018] (6) When the vision camera takes a picture of the battery connector placed on the secondary positioning stage, the four-axis feeding gripper puts the unqualified battery connector into the NG box and then picks up the corresponding battery connector from the buffer stage to replenish it.

[0019] In summary, this invention enables the positioning of the battery connector before the robot picks it up. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figures 1-9 As shown, this utility model provides a battery connector feeding and positioning mechanism, including an installation cabinet 1, a feeding mechanism 2 is provided inside the installation cabinet 1, a four-axis feeding gripper 3 is provided on the top of the installation cabinet 1, and a secondary positioning mechanism 4 is provided on the top of the installation cabinet 1 behind the four-axis feeding gripper 3.

[0032] In this embodiment, the feeding mechanism 2, the four-axis feeding gripper 3, and the secondary positioning mechanism 4 can be configured as two, which can realize dual workstations and improve work efficiency.

[0033] The feeding mechanism 2 includes two sets of feeding conveyor lines 21 installed inside the mounting cabinet 1. A feeding lifting arm 22 is installed above each feeding conveyor line 21, and the lifting arm 22 is driven to move up and down by a lifting component 23. A rodless cylinder 24 is fixed to the top of the mounting cabinet 1. A frame disk 25 is fixed to the top of the slider of the rodless cylinder 24, and first suction cups 26 are fixed to the four corners of the frame disk 25. The first suction cups 26 are used to attract the tray disk 300. After all the battery connecting pieces 400 in the tray disk 300 have been fed, the frame disk 25 is moved by the rodless cylinder 24, thereby moving the tray disk 300 to the other side for unloading. An eighth linear guide rail is fixed to the top of the mounting cabinet 1 in front of the rodless cylinder 24. The slider of the eighth linear guide rail is connected to the frame disk 25. The eighth linear guide rail assists in the movement of the frame disk 25, ensuring stable movement.

[0034] The lifting assembly 23 includes a first mounting plate 231 disposed on the rear side of the feeding conveyor line 21. The rear part of the first mounting plate 231 is fixedly connected to the inner top surface of the mounting cabinet 1 via a first triangular plate 232. First linear guide rails 233 are fixed on both the left and right sides of the front part of the first mounting plate 231. The sliders of the first linear guide rails 233 are fixed to the bottom of the feeding lifting arm 22 via a second triangular plate 234. A trapezoidal lead screw 235 is connected to the middle front part of the first mounting plate 231 via a bearing seat. The trapezoidal lead screw 235 is driven to rotate by a first motor 236. The slider of the trapezoidal lead screw 235 is fixedly connected to the rear part of the feeding lifting arm 22. The first motor 236 drives the trapezoidal lead screw 235 to rotate, thereby driving the feeding lifting arm 22 to rise and fall, and consequently, driving the tray 300 on the feeding lifting arm 22 to rise and fall. During the rising and falling process, the first linear guide rails 233 assist the movement of the feeding lifting arm 22, ensuring stable rising and falling of the feeding lifting arm 22.

[0035] The four-axis loading gripper 3 includes a four-axis robot 31, which can be an Estun ER6-700-SR model robot, but is not limited to this. The execution end of the four-axis robot 31 is fixed with a second mounting plate 32. Multiple sets of suction components 33 are fixed to the bottom of the second mounting plate 32. Each suction component 33 includes two second suction cups 332 connected to the second mounting plate 32 via a first fixing frame 331. The second suction cups 332 are used to suction the battery connector 400. A vision camera 35 is fixed to the second mounting plate 32 via a second fixing frame 34. The vision camera 35 is used to take pictures to detect whether the battery connector 400 is reversed, displaced, or has other NG (no good) issues. A vision light source 37 is fixed to the second mounting plate 32 via a third fixing frame 36. The vision light source 37 is used for supplementary lighting to assist the vision camera 35 in taking pictures and detecting defects.

[0036] The secondary positioning mechanism 4 includes a third mounting plate 41 fixed to the top of the mounting cabinet 1. An L-shaped plate 42 is fixed to the third mounting plate 41. The top horizontal plate of the L-shaped plate 42 has multiple placement platforms 43 for placing battery connecting pieces 400. Two second linear guides 44 are also fixed to the third mounting plate 41. The sliders of the two second linear guides 44 are connected to a first moving plate 45, which is driven to move by a first cylinder 46. A third linear guide 47 is fixed to the first moving plate 45, and the number of sliders on the third linear guide 47 is the same as the number of placement platforms 43. The slider of the rail 47 is fixed with a first positioning block 48. The upper end of the first positioning block 48 penetrates the L-shaped plate 42 and is located next to the placement platform 43. A first buffer plate 49 is fixed on the first moving plate 45 next to the first positioning block 48. The first positioning block 48 is connected to the first buffer plate 49 via a second spring 410. When the four-axis loading gripper 3 places the battery connecting piece 400 on the placement platform 43, the first moving plate 45 is driven to move by the first cylinder 46, thereby driving the first positioning block 48 to move and push the battery connecting piece 400 into the placement platform 43, thereby positioning the lateral position of the battery connecting piece 400. During this process, the second linear guide 44 assists the first moving plate 45 in moving; when the first positioning block 48 pushes the battery connecting piece 400 into the placement platform 43 so that the battery connecting piece 400 abuts against the inner wall of the placement platform 43, the first moving plate 45 moves in the opposite direction due to the reaction force, thereby squeezing the second spring 410 and the first buffer plate 49, which plays a buffering role; during this process, the third linear guide 47 assists the first positioning block 48 in moving.

[0037] A second movable plate 411 is located on the top of the mounting cabinet 1, behind the third mounting plate 41. The second movable plate 411 is connected to the mounting cabinet 1 via a slider of a fourth linear guide rail 412. The second movable plate 411 is driven to move back and forth by a second cylinder 413. Multiple second positioning blocks 414 are fixed to the rear of the second movable plate 411, the number of which is the same as the number of placement platforms 43. The second movable plate 411 is driven to move backward by the second cylinder 413, thereby causing the second positioning blocks 414 to push the battery connecting piece 400 into the placement platform 43, thus positioning the longitudinal position of the battery connecting piece 400. During this process, the fourth linear guide rail 412 assists in the movement of the second positioning blocks 414.

[0038] The top of the mounting cabinet 1 is also fixed with an NG frame 7 and a buffer platform 8. The NG frame 7 is used to collect NG materials, and the buffer platform 8 is used to place spare battery connectors 400. When the vision camera 35 takes a picture of the battery connector 400 placed on the secondary positioning platform, the four-axis loading gripper 3 puts the unqualified battery connector 400 into the NG frame 7 and then picks up the corresponding battery connector 400 from the buffer platform 8 to replenish it.

[0039] The working principle of this utility model is as follows: The feeding mechanism 2 controls the feeding conveyor line 21 to transport the manually placed Tray 300 to the feeding lifting arm 22. The feeding lifting arm 22 lifts the Tray 300, and the first suction cup 26 picks up the Tray 300 to the working state.

[0040] The four-axis loading gripper 3 moves above the tray 300. The second suction cup 332 picks up the battery connecting piece 400 in the tray 300 and moves it above the secondary positioning mechanism 4. The battery connecting piece 400 is placed in the placement platform 43 of the secondary positioning mechanism 4. The operation is repeated multiple times to fill all the placement platforms 43.

[0041] After the placement platform 43 of the secondary positioning mechanism 4 is full, the first positioning cylinder and the second positioning cylinder of the secondary positioning mechanism 4 perform precise positioning of the battery connecting piece 400. After positioning is completed, the four-axis loading gripper 3 carries the vision camera 35 to inspect the positioned battery connecting piece 400.

[0042] The above description is only a preferred embodiment of the present utility model and should not be construed as a limitation of this application. All equivalent changes and modifications made within the scope of the patent application of the present utility model should be included in the scope of the present utility model.
