[0023] like Figure 1 As shown, this application provides a battery cell end plate insulation cover assembly production line, which includes an end plate feeding device 10, an insulation cover feeding device 20, a gripping device 30, a secondary positioning device 40, and a battery cell assembly device 50.

[0024] The end plate feeding device 10 is used for feeding and unloading the end plate 1. It includes an end plate feeding line 11, an end plate return line 12 and an end plate unloading line 13 arranged sequentially along the conveying direction. The end plate feeding line 11 and the end plate unloading line 13 are arranged in parallel and in opposite directions. The two ends of the end plate return line 12 are connected to the end of the end plate feeding line 11 and the end of the end plate unloading line 13.

[0025] To ensure the conveying efficiency of the end plates, combined with Figures 2 to 4As shown, the pallets used to place the end plates 1 are generally stacked to form a pallet stack 2. Therefore, in the embodiments of this application, the end plate feeding line 11 has a destacking area 11a, and the end plate unloading line 13 has a stacking area 13a. Both the destacking area 11a and the stacking area 13a are equipped with a destacking machine 14. The destacking machine 14 in the destacking area 11a is used to destacking the pallet stack 2 conveyed by the end plate feeding line, and the destacking machine 14 in the stacking area 13a is used to stack the empty pallets conveyed by the end plate unloading line 13.

[0026] In the embodiments of this application, the top of the tray has a positioning pin and the bottom has a positioning hole, and the stability of the tray stacking is achieved by the cooperation of the positioning hole and the positioning pin.

[0027] The insulating cover feeding device 20 is used for loading and unloading the insulating cover 3. The insulating cover 3 is also transported using a corresponding pallet, but the pallets are not stacked, so a common conveyor line can be used.

[0028] Similar to the end plate feeding device 10, the insulating cover feeding device 20 includes an insulating cover loading line 21 and an insulating cover unloading line 22. In the embodiments of this application, the loading line, return line and unloading line are all spaced roller conveyor lines to ensure that the line can be conveyed normally when the tray is blocked to any position on the line.

[0029] The insulating cover feeding device 20 and the end plate feeding device 10 are arranged in parallel to ensure the synchronous feeding of the two materials.

[0030] In this application, combined with Figures 2 to 5 As shown, the stacker 14 includes a frame 141, a top material mechanism 142, and a lifting mechanism 143.

[0031] The frame 141 has passageways at both ends for material passage; the top material mechanism 142 is located at the lower part of the frame 141 and is used to lift the pallet stack 2 from the lower end.

[0032] Specifically, the lifting mechanism 142 includes a lifting cylinder 1421, a lifting base 1422, and four lifting columns 1423 located on the lifting base 1422. The four lifting columns 1423 are distributed at the four corners of the pallet stack 2. The upper ends of the two diagonally opposite lifting columns 1423 have positioning pins that correspond to the positioning holes at the bottom of the pallet. The lifting columns 1423 can extend from the gaps in the spacers to lift the pallet.

[0033] The lifting mechanism 143 is located on the upper part of the frame 141. The lifting mechanism 143 can be fixed and lifted from the side with the pallet stack 2.

[0034] Specifically, the material lifting mechanism 143 is located on both sides of the frame 141, and includes a material lifting arm 1431, a movable pin 1432, a first drive unit 1433, and a second drive unit 1434.

[0035] The lifting arm 1431 is mounted on the frame 141 in a vertically arranged guide rod. The first drive unit 1433 is a lifting cylinder used to drive the lifting arm 1431 to rise and fall. The movable pin 1432 is installed at both ends of the lifting arm 1431 and can extend into the frame 141. The second drive unit 1434 is a pin cylinder used to drive the movable pin 1432 to extend or retract. In order to ensure the cooperation and fixation between the movable pin 1432 and the end plate tray 201, the side of the end plate tray 201 has a socket 20a for the insertion of the pin 1432.

[0036] The frame 141 is equipped with a layer number detection sensor 1411, and the lifting mechanism 143 determines the lifting height of the lifting arm 1431 based on the layer number information fed back by the layer number detection sensor 1411.

[0037] When the lifting mechanism 143 provided in this application is in use, when the pallet stack 2 is transported into the frame 141, the lifting cylinder 1421 drives the lifting base 1422 to rise, and the lifting column 1423 extends out from the gap of the spacer rollers to lift the pallet, so that the bottom pallet is separated from the support surface of the conveyor line. Then, the lifting mechanism 143 determines the extension length of the first drive unit 1433 according to the layer number information fed back by the layer number detection sensor 1411, ensuring that the lifting arm 1431 descends to a suitable height so that the movable pin 1432 corresponds to the insertion hole on the second to last layer pallet. The second drive unit 1434 drives the movable pin 1432 to extend and engage with the insertion hole, so that the lifting arms 1431 on both sides... The upper end plate tray 201 is "scooped" up from both sides, and then the first drive unit 1433 retracts to separate the upper tray from the bottom tray. Then the lifting cylinder 1421 retracts, so that the bottom tray returns to the support surface of the conveyor line. The bottom tray continues to move forward under the drive of the conveyor line until it leaves the frame 141. Then the second drive unit 1434 extends downward, so that the upper tray is close to the support surface of the conveyor line. Then the lifting cylinder 1421 extends, so that the lifting column 1423 catches the descending pallet stack and places it on the support surface of the conveyor line. The second drive unit 1434 drives the movable pin 1432 to retract, thus completing the entire process of unstacking the bottom tray from the pallet stack.

[0038] During the stacking process, the upper pallet is first lifted by the top material mechanism 142, then the lifting mechanism 143 lifts it from both sides and then places the bottom pallet under the upper pallet from the bottom. Finally, the lifting mechanism 143 lowers the upper pallet to the top of the bottom pallet, and the movable pin 1432 retracts, thus realizing the stacking.

[0039] Combination Figure 6 and Figure 7 As shown, the material gripping device 30 includes a combination clamp 31 and a gripper robot 32. The combination clamp 31 is disposed on the hand of the gripper robot 32. The combination clamp 31 can selectively grip or place the end plate 1 and / or the insulating cover 3.

[0040] The combined fixture 31 includes two gripping units, which can work simultaneously to grip and place materials. Each gripping unit includes an end plate gripper 311, an insulating cover suction cup 312, and an insulating cover pressure claw 313.

[0041] The end plate gripper 311 includes two end plate gripping arms 3111 that can open or close relative to each other. The end plate gripping arms 3111 are driven by corresponding cylinders to move to both sides to clamp the ends of the end plate 1.

[0042] The insulating cover suction cup 312 is used to pick up the insulating cover, wherein the insulating cover suction cup 312 and the end plate gripper 311 are arranged to avoid conflict between their actions.

[0043] The insulating cover clamping claw 313 is used to clamp the positioned insulating cover 3 onto the side of the end plate 1 held by the end plate clamping claw 311. Specifically, the insulating cover clamping claw 313 includes a clamping arm 3131 and a clamping block 3132 disposed near the end plate clamping arm 3111. The clamping arm 3131 is driven by a corresponding cylinder to move to both sides. The clamping block 3132 is connected to the end of the clamping arm 3131. The clamping block 3132 can cooperate with the end plate clamping arm 3111 to clamp the insulating cover onto the side of the end plate 1.

[0044] The secondary positioning device 40 is used for stacking and positioning the insulating cover 3 and the end plate 1 before assembly.

[0045] Among them, combined Figure 8 and 9 As shown, the secondary positioning device 40 includes a frame 41, on which at least one positioning component 42 is provided. The positioning component 42 includes a support base 421, a positioning reference component 422, and a pushing mechanism 423. The support base 421 is used to stack the insulating cover 3 and the end plate 1 in sequence.

[0046] The positioning reference component 422 and the pushing mechanism 423 are respectively disposed on opposite sides of the support base 421. The pushing mechanism 423 is used to push and position the insulating cover 3 and end plate 1 stacked on the support base 421 toward the positioning reference component 422. In the embodiment of this application, the support base 421 has a cuboid structure. The positioning reference component includes a first positioning plate 4221 and a second positioning plate 4222. The first positioning plate 4221 and the second positioning plate 4222 are respectively fixedly disposed on two adjacent sides of the support base 421. The pushing mechanism 423 includes a first pushing cylinder 4231 and a second pushing cylinder 4232. The system includes a material cylinder 4232, a first pusher plate 4233, and a second pusher plate 4234. The first pusher plate 4233 is connected to the first pusher cylinder 4231 and is positioned opposite to the first positioning plate 4221. The first pusher plate 4233 can be pushed towards the side closer to the first positioning plate 4221 under the drive of the first pusher cylinder 4231. The second pusher plate 4234 is connected to the second pusher cylinder 4232 and is positioned opposite to the second positioning plate 4222. The second pusher plate 4234 can be pushed towards the side closer to the second positioning plate 4222 under the drive of the second pusher cylinder 4232.

[0047] In the embodiments of this application, the positioning component 42 further includes a first positioning sensor 424 and a second positioning sensor 425. Specifically, the support base 421 has an opening in the middle, the first positioning sensor 424 is disposed in the opening and is used to detect whether the insulating cover 3 is placed in place, and the second positioning sensor 425 is disposed on one side of the support base 421 and is used to detect whether the end plate 1 is placed in place. The first pushing cylinder 4231 and the second pushing cylinder 4232 are configured to start working only after both the first positioning sensor 424 and the second positioning sensor 425 have reported that the material is placed in place.

[0048] When the secondary positioning device 40 is in use, driven by the gripper robot 32, the insulating cover suction cup 312 first places the insulating cover 3 on the support base 421, and the end plate gripper 311 places the end plate 1 above the insulating cover. With the first positioning plate 4221 and the second positioning plate 4222 as positioning references, the first pusher plate 4233 and the second pusher plate 4234 push the insulating cover 3 and the end plate 1 to position.

[0049] Combination Figures 10 to 13 As shown, the cell assembly device 50 is used to assemble the insulating cover 3 and the end plate 1 at both ends of the cell module.

[0050] The cell assembly device 50 includes a cell conveying line 51, a cell straightening assembly 52, and a cell shaping assembly 53.

[0051] The conveying direction of the cell conveying line 51 is consistent with the stacking direction of the cells in the cell module 6, and the cell conveying line 51 has a cell shaping area 51a.

[0052] The cell alignment assembly 52 includes two alignment mechanisms located on both sides of the cell conveying line 51 and corresponding to the cell shaping area 51a, for pushing and clamping the cell module 6 located in the cell shaping area 51a.

[0053] In the embodiments of this application, the push-alignment mechanism includes a push-alignment cylinder 521, a push-alignment connecting rod 522, and a push-alignment plate 523.

[0054] The push-aligning cylinder 521 is installed on the side of the cell conveying line 51. The push-aligning plate 523 is connected to the cylinder shaft of the push-aligning cylinder 521 through the push-aligning connecting rod 522. The push-aligning plates 523 on both sides cooperate to press the cell module 6 located in the cell shaping area 51a tightly, preventing the cell from spreading out and falling down to both ends.

[0055] The cell shaping assembly 53 includes a shaping tray 531 and a pressing mechanism. The shaping tray 531 can be conveyed along the cell conveying line 51. The shaping tray 531 has a cell receiving groove arranged along the conveying direction of the cell conveying line 51.

[0056] The clamping mechanism 532 includes a fixed base 5321, a movable base, and a clamping drive 5323. The fixed base 5321 is disposed at one end of the cell receiving groove 531a. The clamping drive 5323 is used to drive the movable base 5322 to slide along the cell receiving groove to approach or move away from the fixed base 5321.

[0057] When the battery cell assembly device 50 is in use, the battery cell module 6 on the shaping tray 531 is pressed against the fixed base 5321 and the movable base 5322, which drives the battery cell module 6 to move to the battery cell shaping area 51a. Then, the push-aligning cylinder 521 extends, and the push-aligning plates 523 on both sides cooperate to press against the side of the battery cell module 6. Then, the movable base 5322 that presses the battery cell module 6 moves away from the fixed base 5321, forming a gap at the end of the battery cell module 6. Driven by the gripper robot 32, the end plate gripper 311 and the insulating cover gripper 313 insert the pressed end plate 1 and the insulating cover 3 into the gap. Then, the movable base 5322 moves closer to the movable fixed base 5321, completing the assembly of the end plate 1 and the insulating cover.

[0058] In the embodiments of this application, combined with Figure 14 As shown, several blocking mechanisms 61 are sequentially arranged on the end plate feeding line 11, the end plate unloading line 13 and the cell conveying line 51.
