[0002] A battery refers to a cup, trough or other container or part of the space of a composite container that contains an electrolyte solution and metal electrodes to generate an electric current. It is a device that can convert chemical energy into electrical energy. In daily life, lithium-ion batteries are a very common type of battery. Lithium-ion batteries have four key materials: positive electrode, negative electrode, separator, and electrolyte. The important thing is that they rely on the insertion and separation of lithium ions between the two electrodes and operate by moving lithium ions between the positive and negative electrodes.

[0003] Due to the stacked structure of lithium-ion battery cells, each processing step is manually fed and loaded during lamination. The die-cut pole pieces need to be manually moved to each lamination loading position, and one worker is required to be responsible for each feeding position. This practice increases production costs, and the manual work efficiency is low. The overall work flexibility and accuracy still need to be improved.

[0004] In summary, in order to solve this problem, it is urgent to propose an automated single-piece conveying and discharging device for positive and negative electrode sheets. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment: A device for conveying and discharging a single piece of positive and negative electrode sheets, such as Figure 1-Figure 3As shown, it includes a support frame 1, a rodless cylinder 2, a slider 3, a push plate 4, a limit rod 6, an electric slide rail 7, a connecting plate 8, an elastic member 81, a support plate 9, an electric suction cup 10, a contact block 11 and an inclined rod 12. The front positions of the left and right parts of the support frame 1 are fixedly installed with rodless cylinders 2. Slide blocks 3 are slidably set on the two rodless cylinders 2. The sliders 3 are set inwardly. A push plate 4 is set between the two sliders 3. The push plate 4 is located inside the support frame 1, and the push plate 4 is used for placing the positive and negative electrode wafers. The push plate 4 is driven by the rodless cylinder 2 to move up and down, thereby completing the transportation of the positive and negative electrode wafers. Limit rods 6 are set on both sides of the top of the support frame 1. The limit rods 6 are set downward to limit the motion trajectory of the overall transportation. Electric slide rails 7 are set on the top of the limit rods 6. The two electric slide rails 7 are slidably set with A connecting plate 8, a support plate 9 is slidably arranged between the two connecting plates 8, the connecting plate 8 is embedded in the support plate 9 in a through-type, and the bottom ends of the connecting plates 8 and the support plates 9 are in abutment with each other, which is suitable for limiting the operation of the two, an elastic member 81 is arranged between the support plate 9 and the connecting plate 8 on the same side, the elastic member 81 is a spring, which can be used to assist the resetting of the support plate 9, and four electric suction cups 10 are arranged at the bottom of the support plate 9, and the electric suction cups 10 are used for adsorbing the positive and negative electrode monoliths, and contact blocks 11 are arranged on the left and right sides of the support plate 9, and the contact blocks 11 are in an outwardly extending state to play a limiting role, and an inclined rod 12 is arranged on the top of the electric slide rail 7, the rear end of the inclined rod 12 is flat, and the front end thereof is inclined, and the inclined rod 12 is in contact with the adjacent contact block 11, which is used to limit the contact block 11 and simultaneously push the support plate 9 to shake and discharge.

[0021] like Figure 1 and Figure 2 As shown, it also includes a sensor 21, which is arranged at the upper side of the rear part of the rodless cylinder 2, and the sensor 21 is used to sense the height of the positive and negative electrode sheets, so as to control the operating frequency of the rodless cylinder 2; a limit plate 5, a limit plate 5 is arranged on the front and rear inner sides of the support frame 1, and the limit plate 5 is arranged to fit the inner wall of the support frame 1, and is used to limit the position of the positive and negative electrode sheets; an auxiliary rod 13, an auxiliary rod 13 is fixedly arranged at the front center position of the support plate 9, and the auxiliary rod 13 is inclined downward, and its two ends are in an extended state and the width is greater than the support plate 9, which is suitable for assisting the discharge operation of the positive and negative electrode sheets; a wiping cotton 14, a wiping cotton 14 is arranged on the auxiliary rod 13, and the wiping cotton 14 can protect the discharge of the positive and negative electrode sheets to avoid damage due to friction.

[0022] When it is necessary to transport the positive and negative electrode sheets of the battery, the staff first places the entire device on a horizontal plane, and then places the positive or negative electrode sheets to be transported in the support frame 1, so that they are laid flat on the push plate 4, and at the same time, the limit plate 5 blocks the surrounding positions of the support frame 1 to prevent the positive and negative electrode sheets from being misplaced. At this time, the push plate 4 is at the bottom position of the device, and the positive and negative electrode sheets are continuously stacked until their height exceeds the highest point of the limit plate 5. Then the rodless cylinder 2 can be started, and the slider 3 connected thereto is driven by the rodless cylinder 2 to move upward, and at the same time, the push plate 4 is driven upward, so that the uppermost positive and negative electrode sheets are in contact with the electric suction cup 10, and the electric suction cup 10 adsorbs the positive and negative electrode sheets, so that the uppermost layer is separated from the positive and negative electrode sheets as a whole, and at the same time, the sensor 21 senses the height of the positive and negative electrode sheets, thereby controlling the overall operating frequency of the rodless cylinder 2, and then The electric slide rail 7 drives the connecting plate 8 to move backward, thereby driving the supporting plate 9 connected thereto, and then driving the electric suction cup 10 that has adsorbed the positive and negative electrode single pieces to move. During the operation, the overall movement trajectory operates along the trajectory of the limit rod 6 and the electric slide rail 7. At this time, the contact blocks 11 on both sides of the support plate 9 are against between the limit rod 6 and the inclined rod 12, so that the support plate 9 as a whole tends to move downward, and the elastic member 81 connected thereto is in a stretched state. When the contact block 11 is freed from the restriction of the inclined rod 12 by moving backward, the elastic member 81 is not restricted and resets, thereby driving the support plate 9 and the electric suction cup 10 to move upward, so that the positive and negative electrode single pieces fall off from the electric suction cup 10 due to shaking. At the same time, the auxiliary rod 13 is against the front end position of the positive and negative electrode single pieces, and the wiping cotton 14 protects the contact with the positive and negative electrode single pieces, assists the overall falling off, thereby completing the transportation and discharging operation of the positive and negative electrode single pieces.
