The feeding mechanism 100, the weighing mechanism 300 and the discharging mechanism 500 are arranged in sequence along the weighing direction. The taking mechanism 200 is set up at the feeding mechanism 100 and the weighing mechanism 300, and can go back and forth between the feeding mechanism 100 and the weighing mechanism 300. The conveying mechanism 400 is set up at the weighing mechanism 300 and the discharging mechanism 500, and can go back and forth between the weighing mechanism 300 and the discharging mechanism 500. The weighing mechanism 300 includes a fixed seat 310, a first lifting unit 320 and a weighing unit 330. The weighing unit 330 is installed on the top of the fixed seat 310, and the first lifting unit 320 is installed at the bottom of the fixed seat 310, and can run upward through the fixed seat 310 and the weighing unit 330.

[0040] Specifically, in the present embodiment, when the positive electrode sheet is weighed, the feeding mechanism 100 conveys the positive electrode sheet, and after conveying to the set position, the taking mechanism 200 absorbs the positive electrode sheet. In the present embodiment, the taking mechanism 200 can absorb five positive electrode sheets at the same time and place them on the first lifting unit 320 of the weighing mechanism 300, and then the first lifting unit 320 moves downward to gently drop the top positive electrode sheet onto the weighing unit 330, and the positive electrode sheet is weighed by the weighing unit 330. After the weighing is completed, the first lifting unit 320 moves upward to lift the positive electrode sheet on the weighing unit 330 again, and at this time, the moving The transport mechanism 400 operates to absorb the positive electrode sheet lifted by the first lifting unit 320 and place it on the unloading mechanism 500, which unloads the positive electrode sheet to finally realize automatic weighing of the positive electrode sheet, thereby reducing manual operation and avoiding damage to the positive electrode sheet. At the same time, the positive electrode sheet is first received by the first lifting unit 320, and then the first lifting unit 320 gently drops the positive electrode sheet onto the weighing unit 330, so as to improve the accuracy of weighing the positive electrode sheet, thereby ensuring the weighing quality, and effectively protecting the weighing unit 330 to increase its service life.

[0041] See also Figures 3 to 7 In order to achieve the weighing of the positive electrode plate, the weighing unit 330 in this embodiment includes a support frame 331, a weighing sensor 332 and a weighing plate 333. The support frame 331 is installed on the fixed base 310, the weighing sensor 332 is arranged on the support frame 331, the weighing plate 333 is connected to the weighing sensor 332, and an avoidance hole 334 is opened on the weighing plate 333, and the first lifting unit 320 includes a first lifting cylinder 321, a first lifting bracket 322 and a first lifting plate 323.

After placement, the first lifting cylinder 321 will drive the first lifting bracket 322 to move downward, and the first lifting bracket 322 will move downward with the first lifting plate 323 during the movement, and then move downward with the first lifting block 324. After the first lifting block 324 moves to the set distance, the positive electrode sheet on the first lifting block 324 will gently fall on the weighing plate 333 of the weighing unit 330. At this time, the weighing sensor 332 will weigh the positive electrode sheet on the weighing plate 333 and feed back the weighing data to the system. When the weighing of the positive electrode sheet is completed, the first lifting cylinder 321 will operate again to drive the first lifting bracket 322 to move upward, and the first lifting bracket 322 will The first lifting plate 323 is moved upward, thereby the first lifting block 324 is moved upward, and when the first lifting block 324 moves upward, the positive electrode sheet on the weighing plate 333 is gently lifted up and lifted to a set height, and then the conveying mechanism 400 absorbs and conveys the positive electrode sheet on the first lifting block 324, thereby completing the automatic weighing of the positive electrode sheet, and the positive electrode sheet is pre-connected by the first lifting block 324, and then gently placed on the weighing plate 333, and its drop can be controlled, so that when the positive electrode sheet falls on the weighing plate 333, it will not cause damage to the symmetrical weighing sensor 332 due to excessive drop, and the symmetrical weighing sensor 332 is effectively protected, and the service life of the weighing sensor 332 is increased. At the same time, through the gentle fall, the weighing data can be ensured to be more accurate, thereby ensuring the weighing quality of the positive electrode sheet of the aqueous zinc ion battery.

The anti-damage bracket 340 can effectively prevent the weighing plate 333 from swinging excessively when the weighing machine is moving or working, thereby protecting the weighing unit 330 and improving the overall service life of the weighing unit 330.

[0046] After the loading mechanism 100 loads the positive electrode sheet to the set position, the material picking moving module 210 will drive the material picking bracket 220 to move to the loading mechanism 100, and the material picking cylinder 230 will drive the material picking nozzle 240 to move downward, and the positive electrode sheet will be sucked by the material picking nozzle 240. After sucking, the material picking moving module 210 will drive the material picking bracket 220 horizontally again to move the material picking bracket 220 to the weighing mechanism 300, and the material picking cylinder 230 will drive the material picking nozzle 240 to move downward, and the material picking nozzle 240 will place the sucked positive electrode sheet on the first lifting block 324 of the first lifting unit 320, so as to complete the automatic picking of the positive electrode sheet; when the weighing of the positive electrode sheet is completed, the transport moving module 410 drives the transport bracket 420 to move horizontally, so that it moves to the weighing mechanism 300. At the mechanism 300, the transport cylinder 430 drives the transport suction nozzle 440 to move downward, and after moving into position, the transport suction nozzle 440 sucks the positive electrode sheet on the first lifting block 324, and then the transport moving module 410 drives the transport bracket 420 to move horizontally again, and moves to the unloading mechanism 500, and the transport cylinder 430 drives the transport suction nozzle 440 to move downward again, and the transport suction nozzle 440 places the sucked positive electrode sheet to the corresponding position of the unloading mechanism 500, thereby completing the automatic transportation of the positive electrode sheet, and finally, the automatic transportation of the positive electrode sheet is realized through the material picking mechanism 200 and the transport mechanism 500, thereby reducing manual operation and avoiding damage to the positive electrode sheet, and the material picking moving module 210 and the transport moving module 410 are both existing technologies, so they will not be elaborated here.

[0047] See also Figures 10 to 13In order to realize automatic unloading of the positive electrode sheet, the unloading mechanism 500 in this embodiment includes an unloading drum line 510, an unloading fixture 520 and a second lifting unit 530.

[0048] Specifically, when the positive electrode sheet is unloaded, an empty unloading jig 520 is placed on the unloading roller line 510 manually or by a robot, and the unloading roller line 510 drives the unloading jig 520 to be transported. After the unloading jig 520 moves to the set position, the positioning unit 540 blocks and positions the unloading jig 520. After positioning, the second lifting cylinder in the second lifting unit 530 drives the second lifting plate 532 to move upward, so that the second lifting block 533 on the second lifting plate 532 passes through the lifting hole 521 at the bottom of the unloading jig 520 and reaches the top of the unloading jig 520, and the conveying mechanism 400 sucks and places the weighed positive electrode sheet. The second lifting block 533 is placed on the unloading jig 520. After one piece is placed, the second lifting cylinder will drive the second lifting block 533 to move downward a set distance, and so on, until a set number of positive electrode sheets are stacked in the unloading jig 520. After the stacking is full, the second lifting cylinder will drive the second lifting block 533 to move out of the lifting hole 521 at the bottom of the unloading jig 520, and the positioning unit 540 will reset and no longer block the unloading jig 520.
