Description

Technical Field

[0001] This invention relates to the field of battery connector assembly technology, and in particular to a battery connector assembly method. Background Technology

[0002] A typical power battery is assembled by connecting several individual cells in series and parallel using a CCS (Cells Contact System) integrated busbar. The CCS integrated busbar consists of an FPC (Flexible Printed Circuit), plastic structural components, and copper / aluminum busbars. Power batteries generally consist of multiple battery modules, and the CCS, as the core component of the power battery safety monitoring center, plays a crucial role in safety. Traditional CCS installation relies mainly on manual insertion of battery connectors into the CCS's plastic structural components. This manual installation method is inefficient, labor-intensive, and time-consuming. This entirely manual assembly process is far from meeting the demands of today's ever-increasing battery production. Summary of the Invention

[0003] The purpose of this invention is to provide a battery connector assembly method that enables precise and efficient installation of battery connectors in the CCS integrated busbar.

[0004] The technical solution of the present invention:

[0005] A battery connector assembly method includes an installation cabinet, a feeding mechanism inside the installation cabinet, a four-axis feeding gripper on the top of the installation cabinet, a secondary positioning mechanism on the top of the installation cabinet behind the four-axis feeding gripper, a lifting and pressing mechanism on the rear side of the installation cabinet, and a six-axis feeding gripper on the rear side of the lifting and pressing mechanism.

[0006] The method is as follows:

[0007] Step 1: The lifting and pressing mechanism lifts the pallet and presses the CCS integrated busbar on the pallet;

[0008] Step 2: The feeding mechanism controls the feeding conveyor line to transport the manually placed tray to the feeding lifting arm. The feeding lifting arm lifts the tray, and the first suction cup picks up the tray to the working state.

[0009] Step 3: The four-axis loading gripper moves above the tray, and the second suction cup picks up the battery connecting piece from the tray and moves it above the secondary positioning mechanism. The battery connecting piece is then placed into the placement platform of the secondary positioning mechanism. This operation is repeated multiple times to fill all the placement platforms.

[0010] Step 4: After the placement platform of the secondary positioning mechanism is full, the first and second positioning cylinders of the secondary positioning mechanism perform precise positioning of the battery connecting piece. After positioning is completed, the four-axis loading gripper carrying a vision camera inspects the positioned battery connecting piece.

[0011] Step 5: After the inspection is completed, the six-axis loading gripper moves to the top of the secondary positioning mechanism. The third suction cup of the six-axis loading gripper picks up the battery connecting piece and moves it to the top of the CCS integrated busbar. The third suction cup is made to float by the axis compensator of the six-axis loading gripper. The plane of the third suction cup is tilted at a certain angle relative to the CCS integrated busbar to insert the battery connecting piece into the slot of the CCS integrated busbar.

[0012] Step 6: After the third suction cup returns to center, it presses down on the battery connector. During the pressing process, the vertical error is compensated by the compression of the first spring. The battery connector assembly is completed by the above actions.

[0013] Furthermore, in step 4, during the process of the four-axis loading gripper carrying a vision camera to detect the battery connecting piece that has been positioned, it is determined whether the battery connecting piece has an NG problem. The battery connecting piece with an NG problem is treated as NG material and transferred to the NG box by the four-axis loading gripper.

Detailed Implementation

[0045] The invention will now be further described with reference to the accompanying drawings.

[0046] like Figures 1-17 As shown, the present invention provides a battery connector assembly method, 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, a secondary positioning mechanism 4 is provided on the top of the installation cabinet 1 behind the four-axis feeding gripper 3, a lifting and pressing mechanism 5 is provided on the rear side of the installation cabinet 1, and a six-axis feeding gripper 6 is provided on the rear side of the lifting and pressing mechanism 5.

[0047] The method is as follows:

[0048] Step 1: The lifting and pressing mechanism 5 lifts the pallet 100 and presses the CCS integrated busbar 200 on the pallet 100;

[0049] Step 2: 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.

[0050] Step 3: 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.

[0051] Step 4: 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 the positioning is completed, the four-axis feeding gripper 3 carries the vision camera 35 to inspect the positioned battery connecting piece 400.

[0052] Step 5: After the inspection is completed, the six-axis loading gripper 6 moves above the secondary positioning mechanism 4. The third suction cup 613 of the six-axis loading gripper 6 picks up the battery connecting piece 400 and moves the battery connecting piece 400 above the CCS integrated busbar 200. The shaft compensator 612 of the six-axis loading gripper 6 makes the third suction cup 613 float. The plane of the third suction cup 613 is tilted relative to the CCS integrated busbar 200 at a certain angle to insert the battery connecting piece 400 into the slot of the CCS integrated busbar 200.

[0053] Step 6: After the third suction cup 613 returns to center, it presses down on the battery connector 400. During the pressing process, the vertical error is compensated by the compression of the first spring. The assembly of the battery connector 400 is completed by the above actions.

[0054] In this embodiment, the feeding mechanism 2, the four-axis feeding gripper 3, the secondary positioning mechanism 4, and the six-axis feeding gripper 6 can be configured as two, which can realize dual workstations and improve work efficiency.

[0055] In step 4, during the process of the four-axis loading gripper 3 carrying the vision camera 35 to detect the battery connecting piece 400 that has been positioned, it is determined whether the battery connecting piece 400 has reversed or shifted, etc. If the battery connecting piece 400 has an NG problem, it is treated as NG material and transferred to the NG frame 7 by the four-axis loading gripper 3. After the NG material is full, the NG frame 7 is manually removed.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] The lifting and pressing mechanism 5 includes a first conveyor line 51, a base 52 below the first conveyor line 51, and a fourth mounting plate 53 above the base 52. U-shaped seats 54 are fixed to the left and right ends of the bottom of the fourth mounting plate 53, and the left and right ends of the bottom of the U-shaped seats 54 are connected to the top of the base 52 via sliders of a fifth linear guide rail 55. The fourth mounting plate 53 is driven to move back and forth by two third cylinders 56. The push plates of the third cylinders 56 are not connected or fixed to the fourth mounting plate 53. One end of a third spring 58 is connected to the base 52 via a support block 57, and the other end of the third spring 58 is connected to a stop block 59. The third spring 58 acts as a buffer when the fourth mounting plate 53 moves horizontally, preventing the battery connector 400 from causing the CCS integrated busbar 200 to shift during installation. The third cylinders 56 can center the fourth mounting plate 53 (the spring force of the third spring 58 is insufficient to return the fourth mounting plate 53 to its original position, so the third cylinders 56 assist). The fifth linear guide rail 55 can assist the movement of the fourth mounting plate 53.

[0062] A lifting plate 511 is provided above the fourth mounting plate 53. The lifting plate 511 is driven to rise and fall by the fifth cylinder 512. Sliding shafts 513 are fixed at the four corners of the bottom of the lifting plate 511. The sliding shafts 513 are connected to the fourth mounting plate 53 via bushings 514. The lower end of the sliding shafts 513 is fixed on a baffle 515. A fourth cylinder 510 is fixed on the base 52. The push rod of the fourth cylinder 510 is connected to a positioning pin 522. The fourth mounting plate 53 has a positioning hole (not shown) for the positioning pin 522 to pass through. The fifth cylinder 512 can drive the lifting plate 511 to rise, thereby driving the tray 100 and the CCS integrated busbar 200 on the tray 100 to rise. During this process, the sliding shafts 513 and bushings 514 cooperate to assist in the lifting, so that the lifting can be stable. Before the fifth cylinder 512 drives the lifting plate 511 to lift, the fourth cylinder 510 drives the positioning pin 522 through the positioning hole, and then the fifth cylinder 512 drives the lifting plate 511 to lift. This prevents the lifting plate 511, the tray 100 and the CCS integrated busbar 200 on the tray 100 from moving horizontally when the fourth mounting plate 53 moves horizontally during the lifting process.

[0063] The number of the fourth cylinder 510 can be two, but is not limited to this.

[0064] A fifth mounting plate 516 is fixed to the outer side of each of the two bases of the first conveyor line 51. A sixth cylinder 517 is fixed to the fifth mounting plate 516. A mounting rod 518 is fixed to the push rod of the sixth cylinder 517. Multiple clamping plates 519 are fixed to the top of the mounting rod 518. A sixth linear guide 520 is fixed to both the left and right ends of the fifth mounting plate 516. The slider of the sixth linear guide 520 is fixedly connected to the mounting rod 518 via a connecting plate 521. By driving the mounting rod 518 downward with the sixth cylinder 517, the clamping plates 519 can be driven downward to clamp the CCS integrated busbar 200. During this process, the sixth linear guide 520 can assist the mounting rod 518 in downward pressing, enabling stable movement.

[0065] The six-axis loading gripper 6 includes a six-axis robot 61, which can be a KUKA KR-70-R2100 model robot, but is not limited to this. The execution end of the six-axis robot 61 is fixed with a mounting frame 62. A seventh mounting plate 63 and a sixth mounting plate 64 are disposed below the mounting frame 62. The seventh mounting plate 63 is connected to the bottom of the mounting frame 62 via a slider of a seventh linear guide 65. The sixth mounting plate 64 is fixedly connected to the bottom of the mounting frame 62 via a fixing block 66. The seventh mounting plate 63 is driven to move left and right by a seventh cylinder 67. The seventh cylinder 67 can move the seventh mounting plate 63 and the third suction cup 613, thereby adjusting the distance between the seventh mounting plate 63 and the sixth mounting plate 64 to match the corresponding installation position. The sixth mounting plate 64 serves as the reference end. During this process, the seventh linear guide 65 assists the movement of the seventh mounting plate 63, enabling stable movement.

[0066] Multiple eighth cylinders 68 are fixed to the bottom of both the seventh mounting plate 63 and the sixth mounting plate 64. The push rod of each eighth cylinder 68 is fixed to an upper support plate 69, which is connected to a lower support plate 611 via multiple fourth springs 610. The lower support plate 611 is connected to the mounting box via a shaft compensator 612. The shaft compensator 612 can be a Zimmer XYR1040-B model compensator, but is not limited to this. A third suction cup 613 is provided at the bottom of the mounting box. The shaft compensator 612 allows the third suction cup 613 to float. The plane of the third suction cup 613 is tilted relative to the CCS integrated busbar 200 at a certain angle, inserting the battery connector 400 into the slot of the CCS integrated busbar 200. After the third suction cup 613 returns to its upright position, the eighth cylinder 68 drives the mounting box to press down. During the pressing process, the fourth springs 610 compress the box to compensate for vertical errors.

[0067] 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.

[0068] The above description is only a preferred embodiment of the present invention and should not be construed as a limitation of this application. All equivalent changes and modifications made in accordance with the scope of the patent application of the present invention should be covered by the present invention.
