Description

Technical Field

[0001] This utility model relates to the field of lithium battery production and assembly technology, specifically a material handling mechanism for an assembly line of explosion-proof combined caps for cylindrical lithium batteries. Background Technology

[0002] A lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. The lithium battery cap is a key component on the top of the lithium battery. It is usually made of a combination of various materials, including metals and plastics. The shape and size of the cap vary depending on the type and specifications of the lithium battery. It is generally round or square, and its size is just enough to cover the opening of the positive or negative electrode of the battery.

[0003] Chinese Patent Publication No. CN 217995991 U discloses a cylindrical lithium battery explosion-proof combined cap feeding device, including an air pipe connector, a buckle, a feeding rod sleeve, a feeding rod, and a spring. One end of the air pipe connector is connected to the feeding rod sleeve via the buckle, and one end of the feeding rod sleeve is connected to the feeding rod via the spring. The bottom end of the feeding rod has a cap suction groove. An air pipe is installed inside the air pipe connector, and one end of the air pipe is connected to the cap suction groove.

[0004] The aforementioned material-picking device uses negative pressure adsorption to pick up materials from a distance. However, current battery cap transport devices generally use split-type direct vibration tracks, which can cause problems such as caps tilting upwards and side damage during transport. The aforementioned material-picking device can only ensure that the battery caps are not damaged during adsorption and transfer, but the problems that occur during the process of the battery caps moving to the material-picking device cannot be avoided.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The transport assembly includes two belts, with the battery cap located between the two belts and its two sides respectively abutting against the two belts; multiple rollers are evenly arranged below the battery cap to support it; the partition assembly includes a storage plate, which has a groove for temporarily storing the battery cap on the side near the belt, and an infrared sensor is provided on the side of the groove away from the belt, the infrared sensor being embedded in the storage plate; a cover plate is provided above the storage plate, the end of which is fixedly connected to a cylinder, and the bottom of the cylinder and the bottom of the storage plate are both fixedly connected to the top of the support frame.

[0009] The transfer assembly includes an adsorption cylinder with a circular groove at the bottom for storing battery caps; the top of the adsorption cylinder is fixedly connected to the bottom of a connecting tube, the top of the connecting tube is fixedly connected to a flexible tube, and the end of the flexible tube away from the connecting tube is fixedly connected to a negative pressure pump.

[0010] As a further technical solution of this utility model, both ends of the inner sides of the two belts are connected to connecting shafts, and multiple inner shafts are evenly arranged between the two connecting shafts of the same belt; the bottom of the connecting shaft at one end of the two belts is fixedly connected to the output shaft of the two motors respectively.

[0037] Both inner ends of the two belts 14 are connected to a connecting shaft 17, and multiple inner shafts 18 are evenly arranged between the two connecting shafts 17 of the same belt 14; the bottom of the connecting shaft 17 at one end of the two belts 14 is fixedly connected to the output shaft of the two motors 13 respectively.

[0038] By adopting the above technical solution, the product is supplied through direct vibration during the cap assembly process. When the material is full, there is no need for misaligned cutting. The cover plate 22 is pushed by cylinder 23 so that the cover plate 22 no longer blocks the battery cap 3 in the temporary storage plate 21, and the transfer component 6 can then pick up the material. Conversely, when the cover plate 22 covers the groove on the temporary storage plate 21, the product can be fed through the direct vibration track and detected by the infrared sensor 25 in the groove. When the material is full, the cycle is repeated. The improvement can avoid the stacking of materials and side damage caused by the immature material picking mechanism during the cap assembly process, thereby improving the safety and pass rate of the cap.

[0039] In this embodiment, both ends of the plurality of connecting shafts 17 and the plurality of inner shafts 18 are rotatably connected to the inner wall of the outer casing 11, and both belts 14 are located inside the outer casing 11; the central shafts at both ends of the plurality of rollers 15 are rotatably connected to the two side plates 16, and the bottom of the two side plates 16 are fixedly connected to the outer casing 11; both motors 13 are fixedly connected to the bottom of the outer casing 11, and the bottom ends of the outer casing 11 are fixedly connected to the tops of the two uprights 12, respectively.

[0041] An L-shaped bracket 66 is fixedly connected to one side of the connecting seat 65, and the end of the L-shaped bracket 66 away from the connecting seat 65 is fixedly connected to the top of the connecting pipe 68.

[0042] The end of the connecting seat 65 away from the L-shaped frame 66 is fixedly connected to the second slide 64, and the side of the second slide 64 away from the second slide 64 is slidably connected to the first slide 61; the side of the first slide 61 away from the second slide 64 is connected to the linear module 4 for transmission.

[0044] By adopting the above technical solution, the two belts 14 rotate in opposite directions and work together to drive the battery cap 3 to move through friction. Only one battery cap 3 can pass between the two belts 14, so the battery caps 3 can be moved one by one to the temporary storage plate 21, thus realizing the orderly transportation of the battery caps 3. Multiple rollers 15 support the battery caps 3, make the battery caps 3 move more smoothly, reduce the working pressure of the belts 14, and prevent the sides of the battery caps 3 from being worn due to friction.

[0045] The working principle of this utility model is as follows: During the cap assembly process, the product is supplied by direct vibration. When the material is full, there is no need for misaligned cutting. The cover plate 22 is pushed by the cylinder 23 so that the cover plate 22 no longer blocks the battery cap 3 in the temporary storage plate 21, and the transfer component 6 can pick up the material. Conversely, when the cover plate 22 covers the groove on the temporary storage plate 21, the product can be fed through the direct vibration track and detected by the infrared sensor 25 in the groove. When the material is full, the cycle is repeated. Through the improvement, the stacking and side damage caused by the immature material picking mechanism during the cap assembly process can be avoided, thereby improving the safety and pass rate of the cap.

[0046] The two belts 14 rotate in opposite directions and work together to move the battery cap 3 through friction. Only one battery cap 3 can pass between the two belts 14, so the battery caps 3 can be moved one by one to the temporary storage plate 21, thus realizing the orderly transportation of the battery caps 3. Multiple rollers 15 support the battery caps 3 and make the movement of the battery caps 3 smoother, reducing the working pressure of the belts 14 and preventing the sides of the battery caps 3 from being worn due to friction.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
