Description

Technical Field

[0002] After the batteries are sealed, a series of tests are required to ensure their quality and safety. Based on the test results, the batteries are divided into qualified and unqualified products, and then the qualified products are placed in the material tray.

[0003] During the process of arranging lithium batteries on a tray, multiple suction cups arranged in parallel are generally used to pick up the lithium batteries. However, for lithium batteries of different specifications, the gap between the suction cups needs to be adjusted. Existing suction devices generally cannot be adjusted and can only pick up batteries of one specification, so their applicability is not strong. Utility Model Content

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1, as Figures 1 to 3 As shown, this utility model proposes a lithium battery sealing body suction device, including a lifting mechanism 1 and a mounting plate 2 installed on the lifting mechanism. The lifting mechanism can drive the mounting plate 2 to move up and down (the lifting mechanism is prior art and will not be described in detail here). It also includes multiple first connecting blocks 3 installed on the mounting plate 2, with suction cups 4 fixedly installed on each first connecting block 3. The suction cups 4 can be used to suction the lithium battery. An adjusting mechanism is installed on the mounting plate 2 to adjust the distance between adjacent first connecting blocks 3. By adjusting the distance between adjacent first connecting blocks 3, the distance between adjacent suction cups 4 can be adjusted, thus allowing the suction cups 4 to accommodate lithium batteries of different specifications.

[0026] It is worth noting that: a fixing plate 301 is fixedly installed on the mounting plate 2, and a slide rail 302 is fixedly installed on the mounting plate 2. One of the first connecting blocks 3 located at the end is fixedly connected to the mounting plate 2 through the fixing plate 301, and the other first connecting blocks 3 are slidably connected to the slide rail 302.

[0027] Furthermore, the adjusting mechanism includes an electric push rod 5 fixedly mounted on the mounting plate 2. The output shaft of the electric push rod 5 is fixedly connected to a first connecting block 3 located at the end and slidably connected to the slide rail 302. A transmission plate 501 is fixedly mounted on the first connecting block 3, and a connecting groove 502 is provided on the transmission plate 501. The connecting groove 502 is slidably connected to the adjacent first connecting block 3. By driving one of the slidable first connecting blocks 3 at the end to move by the electric push rod 5, the first connecting block 3 can drive the transmission plate 501 to move. When multiple first connecting blocks 3 retract, the first connecting blocks 3 that follow the electric push rod 5 will move along the slide rail 302. At this time, the transmission plate 501 will slide on the first connecting blocks 3. After two adjacent first connecting blocks 3 come into contact, the first connecting block 3 pushes the adjacent first connecting block 3 to move, thereby allowing multiple first connecting blocks 3 to come into contact with each other and retract, thereby reducing the distance between two adjacent first connecting blocks 3.

[0028] When it is necessary to increase the distance between two adjacent first connecting blocks 3, the electric push rod 5 drives the first connecting block 3 connected to it to move, which in turn drives the transmission plate 501 to move. At this time, the transmission plate 501 will slide on the first connecting block 3 that is slidably connected to it. When the transmission plate 501 moves to the limit position, it will drive the first connecting block 3 connected to it to move under the action of the transmission plate 501, which will increase the distance between multiple first connecting blocks 3. This will allow the suction cup 4 to pick up two different specifications of lithium batteries, thereby effectively improving applicability and eliminating the need to frequently replace the mounting base of the suction cup 4, effectively reducing the cost of the device.

[0029] The first connecting block 3 is fixedly equipped with an air pipe connector 6, and the first connecting block 3 is provided with an air supply hole 601. The air pipe connector 6 is connected to the suction cup 4 through the air supply hole 601, and multiple suction cups 4 are in the same air path. A negative pressure can be applied to the suction cup 4 by an air pump, and the suction cup 4 can pick up the lithium battery by the negative pressure.

[0030] The working principle of this embodiment is as follows: the lifting mechanism can drive the mounting plate 2 to move up and down, and the suction cup 4 can adsorb the lithium battery. When it is necessary to increase the distance between two adjacent first connecting blocks 3, the electric push rod 5 drives the first connecting block 3 connected to it to move, which in turn drives the transmission plate 501 to move. At this time, the transmission plate 501 will slide on the first connecting block 3 that is slidably connected to it. When the transmission plate 501 moves to the limit position, it will drive the first connecting block 3 connected to it to move under the action of the transmission plate 501, which can increase the distance between multiple first connecting blocks 3, and thus allow the suction cup 4 to pick up two different specifications of lithium batteries, thereby effectively improving the applicability, eliminating the need to frequently replace the mounting base of the suction cup 4, and effectively reducing the cost of the device.

[0031] Example 2, as Figures 4 to 7As shown, based on Embodiment 1, an air-sealing mechanism is installed on the first connecting block 3. This mechanism prevents the remaining suction cups 4 from becoming loose when any one or more suction cups 4 leak air. Since multiple suction cups 4 are in the same air path, when one suction cup 4 leaks air, the suction force of the remaining suction cups 4 will decrease. This is because when one suction cup 4 leaks air, the air pressure in the entire air path will drop as air leaks out of the system. This will reduce the suction force of all parallel suction cups 4. However, to reduce costs and the number of lithium batteries transported at one time, the number of suction cups 4 cannot be reduced, and setting a separate air path and a separate solenoid valve for each suction cup 4 would increase costs significantly. Furthermore, the suction cups 4 are in contact with the surface of the lithium battery sealing body, and dust, oil, and other contaminants may reduce their suction force, causing air leakage. If the surface of the lithium battery sealing body is not smooth, the suction cups 4 may not be able to adhere completely, also leading to air leakage.

[0032] The air-sealing mechanism includes a sealing head 7 rotatably mounted within the air outlet 601. A transmission rod 701 is fixedly mounted on the sealing head 7, passing through one side of the first connecting block 3 and extending to the outside of the first connecting block 3. A drive assembly is mounted on the first connecting block 3 to control the rotation of the sealing head 7 based on whether the suction cup 4 is in contact with the lithium battery. By rotating the sealing head 7, it is possible to control whether the sealing head 7 blocks the air outlet 601. When the sealing head 7 blocks the air outlet 601, even if the corresponding suction cup 4 leaks air, it will not affect the suction force of other suction cups 4 in the air path. When the sealing head 7 does not block the air outlet 601, the air pump can apply negative pressure to the suction cup 4 through the air outlet 601 or silence the negative pressure inside the suction cup 4, thus controlling the suction cup 4 to pick up and place the lithium battery.

[0033] Furthermore, the drive assembly includes a gear 702 coaxially fixedly mounted on the transmission rod 701, a guide groove 703 fixedly mounted on the first connecting block 3, a rack 704 slidably mounted in the guide groove 703, a second connecting block 705 fixedly mounted on the rack 704, and a pressure rod 706 fixedly mounted on the second connecting block 705. The suction cup 4 has a certain degree of elasticity. When the lifting mechanism 1 moves the suction cup 4 towards the lithium battery, it will cause the first connecting block 3 to move downward, and at the same time, it will cause the pressure rod 706 to move downward. When the descending pressure rod 706 contacts the tray holding the lithium battery, it will rise, which will then drive the rack 704 to move along the guide groove 703. Due to the structure of the guide groove 703, the rack 704 can drive the gear 702 to rotate when it moves upward, but it will not drive the gear 702 to rotate when it moves downward. Moreover, when the rack 704 drives the gear 702 to rotate once, it will cause the gear 702 to rotate 90°. When the lithium battery is sucked up, the rising pressure rod 706 will drive the sealing head 7 to gradually seal the air outlet 601. When the lithium battery is placed, the pressure rod will contact the tray holding the lithium battery again. At this time, the sealing head 7 will not seal the air outlet 601, and the negative pressure on the suction cup 4 can be canceled by the air pump, thereby placing the lithium battery.

[0034] A spring 707 is fixedly installed on the pressure rod 706, and the other end of the spring 707 is fixedly connected to the first connecting block 3. The spring 707 can cause the pressure rod 706 to drive the rack 704 to reset when no external force is applied.

[0035] The working principle of this embodiment is as follows: When the lifting mechanism 1 moves the suction cup 4 towards the lithium battery, it will move the first connecting block 3 downward, and at the same time, it will move the pressure rod 706 downward. When the descending pressure rod 706 contacts the tray holding the lithium battery, it will rise, which will then move the rack 704 along the guide groove 703. Due to the structure of the guide groove 703, the rack 704 can push the gear 702 to rotate when it moves upward, but it will not drive the gear 702 to rotate when it moves downward. Moreover, when the rack 704 pushes the gear 702 to rotate once, it will make the gear 702 rotate 90°. When the lithium battery is sucked up, the rising pressure rod 706 will drive the sealing head 7 to gradually seal the air outlet 601. When the lithium battery is placed, the pressure rod will contact the tray holding the lithium battery again. At this time, the sealing head 7 will not seal the air outlet 601, and the negative pressure on the suction cup 4 can be canceled by the air pump, thereby placing the lithium battery.

[0036] The above specific embodiments are merely several optional embodiments of this utility model.
