[0033] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0034] Embodiment 1

[0035] The embodiment of the utility model provides a pole piece patching device, which can make the circulating conveyor belt 1 intermittently output pairs of pole pieces, avoiding outputting a single pole piece, thereby helping to avoid empty processing of pole pieces and improving production efficiency.

[0036] See also Figures 1 to 4 , the pole patch equipment includes:

[0037] The circulating conveyor belt 1 is used for conveying the pole pieces.

[0038] The patch mechanism 2 includes a feeding suction plate 21 for adsorbing the pole piece on the circulating conveyor belt 1, a lifting device 22 for driving the feeding suction plate 21 to rise and fall, and a linear module 23 for driving the lifting device 22 to translate along a set direction, the linear module 23 is used to make the feeding suction plate 21 be in the first feeding position or the second feeding position; a plurality of adsorption holes 201 are arranged on the top surface of the feeding suction plate 21, and the adsorption holes 201 are connected to the vacuum device.

[0039] Specifically, in actual operation, the paired pole pieces should be intermittently transported along the circulating conveyor belt 1. However, during the transportation of the pole pieces, unqualified pole pieces need to be removed, so that only one pole piece is left in the paired pole pieces, and therefore a pole piece needs to be supplemented. In this embodiment, a single pole piece is first removed by the patching mechanism 2, and then the single pole piece is placed next to the next single pole piece, so that all the output pole pieces are in pairs. More specifically, the patch mechanism 2 can first adsorb the electrode on the first filling position or the second filling position through the cooperation of the feeding suction plate 21 and the linear module 23 of the lifting device 22, and separate the electrode from the circulating conveyor belt 1; then, when the electrode incoming from the circulating conveyor belt 1 is a single electrode, after the single electrode moves to the patch position of the patch mechanism 2, the feeding suction plate 21 and the linear module 23 of the lifting device 22 cooperate to stick the previously adsorbed electrode to the corresponding first filling position or the second filling position, so that the electrode on the circulating conveyor belt 1 are all in pairs.

[0040] It should also be added that if the paired pole pieces are both judged as unqualified pole pieces and are recycled, the position where the two pole pieces are located is judged as having no workpiece, and the patch mechanism 2 does not need to act.

[0041] Optionally, the patching mechanism 2 is arranged at one side of the bottom of the circulating conveyor belt 1, and the electrode patching device is also provided with a vacuum adsorption plate, and a plurality of vacuum adsorption holes are arranged in an array on the bottom surface of the vacuum adsorption plate to adsorb the electrode on the belt surface of the circulating conveyor belt 1. The arrangement of the vacuum adsorption plate can make the electrode be sucked to the bottom of the circulating conveyor belt 1 for transportation, thereby completing the patching work. In addition, this arrangement structure is also conducive to optimizing the assembly structure and reducing the overall floor space of the battery production machine series.

[0042] Optionally, a waste recovery box 3, a pole piece visual inspection device and a blanking jet plate 4 are also provided at the bottom of the circulating conveyor belt 1; the blanking jet plate 4 is used to blow the pole pieces of the circulating conveyor belt 1 to the waste recovery box 3, and the pole piece visual inspection device is electrically connected to the patch mechanism 2; the waste recovery box 3 and the patch mechanism 2 are arranged in sequence along the conveying direction of the circulating conveyor belt 1.

[0043] Specifically, the electrode visual inspection device is used to detect whether the electrode is in pairs, and detect the position where the electrode is missing on the circulating conveyor belt 1, so that the patch mechanism 2 can accurately move to the appropriate position to absorb the electrode or patch. The blanking jet plate 4 sprays air to the electrode, and the gas passes through the circulating conveyor belt 1, so that the unqualified electrode falls into the waste recovery box 3.

[0044] Optionally, the pole piece patching device further comprises a discharge jet plate 5 , and the discharge direction of the discharge jet plate 5 is opposite to the discharge direction of the blanking jet plate 4 .

[0045] Specifically, the discharge jet plate 5 sprays gas upward, thereby reducing the adhesion effect between the pole piece and the circulating conveyor belt 1, making it easier for the robot to take the material.

[0046] Optionally, the circulating conveyor belt 1 includes a plurality of conveyor sub-belts spaced apart and parallel to each other; or, a plurality of air-permeable mesh holes are arranged in an array on the circulating conveyor belt 1, so that the gas ejected from the discharge jet plate 5 or the gas ejected from the blanking jet plate 4 can act on the electrode piece. It should also be noted that a vacuum adsorption component is arranged along the conveying path of the circulating conveyor belt 1. During the circulation of the conveyor belt 1, the vacuum adsorption component sucks air so that the electrode piece can be conveyed on the circulating conveyor belt 1, that is, at this time, the electrode piece can be on the top surface of the top of the circulating conveyor belt 1, and can also be on the bottom surface of the bottom of the circulating conveyor belt 1 and be conveyed along the conveying path. The vacuum adsorption component includes a plurality of vacuum adsorption plates, and avoids the positions of the discharge jet plate 5 and the blanking jet plate 4, and the position of the vacuum adsorption plate is fixed.

[0047] Optionally, the lifting device 22 includes a primary lifting assembly 221 and a secondary lifting electric cylinder 222, and the material feeding suction plate 21 is installed on the lifting shaft of the secondary lifting electric cylinder 222; the secondary lifting electric cylinder 222 is installed on the lifting end of the primary lifting assembly 221. Specifically, in this embodiment, the primary lifting assembly 221 first drives the material feeding suction plate 21 to quickly lift to a suitable position, and then the secondary lifting electric cylinder 222 accurately adjusts the height of the material feeding suction plate 21, so as to achieve the purpose of quickly sucking the electrode piece and quickly filling the electrode piece.

[0048] Optionally, the electrode patching device further includes a dust removal device 6, which includes a dust removal plate, and a plurality of dust removal holes are provided on the top surface of the dust removal plate, and the dust removal holes are arranged obliquely; the patching mechanism 2 and the dust removal device 6 are arranged in sequence along the conveying direction of the circulating conveyor belt 1. The dust removal device 6 can effectively remove dust and impurities on the surface of the electrode, which is beneficial to improve the production yield of the battery.

[0049] Optionally, the patch mechanism 2 is also provided with a pressure regulating valve 24 for adjusting the adsorption force of the material feeding suction plate 21, and a pressure switch 25 for controlling the vacuum device to start or stop working. It should also be noted that whether there is an adsorbed electrode on the pressure switch 25 can be determined by whether the pressure switch 25 is turned on.

[0050] Optionally, the pole piece patch device further comprises a mounting frame 7, the endless conveyor belt 1 is mounted on the mounting frame 7, and a rotating driving device for driving the endless conveyor belt 1 to rotate in a circular motion is mounted on the mounting frame 7.
