Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a dual-clamp feeding mechanism for lithium battery cells. Background Technology

[0002] In the manufacturing process of cylindrical lithium batteries, the positive electrode sheet, negative electrode sheet, and separator need to be wound together using the winding needle mechanism of a winding machine. Adjacent positive and negative electrode sheets are isolated by the separator to prevent short circuits. After winding, the cells are fixed with adhesive tape to prevent them from unraveling, ultimately resulting in a bare cell. However, due to the different positions of each station in the automated production equipment, the bare cells, after being wound and adhesive-coated on the winding machine, need to be unloaded and transferred to a conveyor station, and then transported from the conveyor station to other stations. Therefore, it is necessary to provide a mechanism for picking up and unloading bare cells. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a dual-clamp material handling mechanism that can simultaneously handle the material handling and unloading of bare battery cells.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A dual-clamp feeding mechanism includes a feeding assembly located on one side of the winding machine head body and a flipping drive assembly located below the winding machine head body. A head gear is coaxially mounted on the winding machine head body, which drives the winding machine head body to rotate to switch the battery cell's working position. The feeding assembly includes a rotating shaft, a feeding gear, two sets of feeding slide cylinders, and two sets of feeding gripper cylinders. The axis of the rotating shaft is parallel to the axis of the winding machine head. The feeding gear is mounted at one end of the rotating shaft to drive its rotation. The two sets of feeding slide cylinders are mounted opposite each other at the other end of the rotating shaft. The included angle between the material picking slide cylinders is 180 degrees, and the movement direction of the material picking slide cylinders is perpendicular to the axis of the rotating shaft. Two sets of material picking claw cylinders are respectively installed on the two sets of material picking slide cylinders. The material picking slide cylinders are used to drive the material picking claw cylinders to extend and retract toward the winding machine head body. The material picking claw cylinders are used to pick up the battery cells on the material picking station of the winding machine head body. The flipping drive assembly is located below the winding machine head body. It includes a flipping servo motor and a flipping drive gear. The output shaft of the flipping servo motor drives and connects to the flipping drive gear. The flipping drive gear meshes with the head gear and the material picking gear.

[0006] In some embodiments, a turntable is installed on one end of the rotating shaft near the material picking slide cylinder and the material picking claw cylinder; two sets of material picking slide cylinders are installed on the turntable.

[0007] In at least one embodiment, a sliding seat is mounted on the slide of the material picking slide cylinder, and a mounting seat is provided on the material picking claw cylinder. The material picking claw cylinder is fixedly connected to the sliding seat through the mounting seat, and a feeding detection plate is provided on the sliding seat. A proximity switch is provided on the side of the material picking station of the winding machine head body. When the proximity switch senses that the feeding detection plate is in place, it is used to send an electrical command to the material picking mechanism control system to control the operation of the material picking slide cylinder and the material picking claw cylinder.

[0008] In at least one embodiment, the turntable is provided with a first mounting bracket, and the first mounting bracket is provided with a solenoid valve assembly, which is used to control the operation of the material picking slide cylinder and the material picking gripper cylinder.

[0009] The beneficial effects of this utility model are as follows:

[0010] This invention includes a material handling component and a flipping drive component. After the battery cell undergoes the winding and finishing adhesive application processes, the flipping servo motor of the flipping drive component drives the flipping drive gear to rotate. The flipping drive gear simultaneously drives the head gear and the material handling gear to rotate. At this time, the winding machine head rotates one position, switching the battery cell from the adhesive application position to the material handling position. The shaft of the material handling component rotates 180 degrees, rotating the empty material handling gripper cylinder on the shaft to the material handling position. The slide of the material handling slide cylinder extends, driving the material handling gripper to clamp the battery cell. The flipping drive gear continues to drive the head gear and the material handling gear to rotate. The material-grabbing gripper cylinder rotates 180 degrees to the unloading station, thus transferring the battery cell to the conveying station. The flipping drive assembly synchronously flips the material-grabbing assembly with the winding machine head, and the angle between the two sets of material-grabbing slide cylinders is 180 degrees. A single flip of the material-grabbing assembly allows for the switching of the two sets of material-grabbing slide cylinders and gripper cylinders, enabling simultaneous material grabbing and unloading of the battery cell, thus improving production efficiency. This invention has a simple structure, effectively reducing manufacturing costs. Furthermore, the structure of the flipping servo motor and the flipping drive gear ensures high rotational accuracy and stable reliability of the machine head gear and material-grabbing gear.

[0021] like Figures 1-5 As shown, the dual-clamp feeding mechanism of this application embodiment includes a feeding component 2 disposed on one side of the winding machine head body 1, and a flipping drive component 3 disposed below the winding machine head body 1. This utility model is used for feeding cylindrical lithium battery cells after winding, and is applicable to most cylindrical lithium battery cells on the market, including but not limited to 18650 lithium battery cells.

[0022] The winding needle mechanism on the winding machine head body 1 winds the positive electrode sheet, negative electrode sheet, and separator film of the battery together. After winding, it is fixed with finishing tape to prevent the core from unraveling, finally obtaining the bare battery cell 20. The winding machine head body 1 is coaxially mounted with a head gear 11, which is used to drive the winding machine head body 1 to rotate, thereby switching the working position of the battery cell 20, so that the bare battery cell 20 after winding and applying finishing tape can be rotated to the material picking position.

[0023] The material handling assembly 2 includes a rotating shaft 21, a material handling gear 22, two sets of material handling slide cylinders 23, two sets of material handling gripper cylinders 24, and a support base 25. The support base 25 is fixedly mounted above the flipping drive assembly 3. The rotating shaft 21 and the support base 25 are connected by a bearing sleeve 10. The axis of the rotating shaft 21 is parallel to the axis of the winding machine head. The material handling gear 22 is installed at one end of the rotating shaft 21 and is used to drive the rotating shaft 21 to rotate. The two sets of material handling slide cylinders 23 are connected in series. The two sets of material picking slide cylinders 23 are mounted on the other end of the rotating shaft 21. The included angle between the two sets of material picking slide cylinders 23 is 180 degrees, and the movement direction of the material picking slide cylinders 23 is perpendicular to the axis of the rotating shaft 21. The two sets of material picking claw cylinders 24 are respectively mounted on the two sets of material picking slide cylinders 23. The material picking slide cylinders 23 are used to drive the material picking claw cylinders 24 to extend and retract toward the winding machine head body 1. The material picking claw cylinders 24 are used to pick up the battery cells 20 on the material picking station of the winding machine head body 1.

[0024] The flip drive assembly 3 is located below the head body 1 of the winding machine. It includes a flip servo motor 31, a flip drive gear 32, a support base 33, and a reducer 34. The reducer 34 is mounted on the support base 33. The input shaft of the reducer 34 is connected to the flip servo motor 31, and the output shaft is connected to the flip drive gear 32. The flip drive gear 32 meshes with the head gear 11 and the material pick-up gear 22. The flip drive gear 32 can be driven to rotate by the flip servo motor 31, and the flip drive gear 32 can simultaneously drive the head gear 11 and the material pick-up gear 22 to rotate.

[0025] The working principle of the dual-clamp material handling mechanism is as follows: After the battery cell 20 undergoes the winding and finishing adhesive processes, the flip servo motor 31 drives the flip drive gear 32 to rotate. The flip drive gear 32 simultaneously drives the head gear 11 and the material handling gear 22 to rotate. At this time, the winding machine head body 1 rotates one station, switching the battery cell 20 from the adhesive application station to the material handling station. Simultaneously, the rotating shaft 21 of the material handling component 2 rotates 180 degrees, rotating the empty material handling gripper cylinder 24 to the material handling station. The slide of the material handling slide cylinder 23 extends, driving... When the pick-up gripper cylinder 24 approaches the battery cell 20, it closes and clamps the battery cell 20. The winding needle mechanism on the winding machine head body 1 pulls the winding needle away from the middle of the battery cell 20, and the pick-up slide cylinder 23 retracts. At this time, the flip drive gear 32 continues to drive the head gear 11 and the pick-up gear 22 to rotate. The winding machine head body 1 continues to rotate one station. The pick-up gripper cylinder 24 rotates the clamped battery cell 20 180 degrees to the unloading station. The pick-up gripper cylinder 24 opens, and the battery cell 20 is transferred to the conveying station. The work cycle is thus completed.

[0026] This invention, by setting a flipping drive component 3, enables the material picking component 2 and the winding machine head body 1 to flip synchronously, and the included angle between the two sets of material picking slide cylinders 23 is 180 degrees. The material picking component 2 can switch between the two sets of material picking slide cylinders 23 and material picking claw cylinders 24 by flipping once, and can simultaneously pick up and unload the battery cell 20, thereby improving production efficiency. This invention has a simple structure, effectively reducing production and manufacturing costs. Moreover, the flipping drive component 3 is a structure of flipping servo motor 31 and flipping drive gear 32, which has high rotational accuracy and is stable and reliable.

The material-picking claw cylinder 24 is fixedly connected to the sliding seat 231 through the mounting seat 241. A feeding detection piece 4 is provided on the sliding seat 231. A proximity switch 5 is provided next to the material-picking station of the winding machine head body 1. When the proximity switch 5 senses that the feeding detection piece 4 is in place, it is used to send an electrical command to the material-picking mechanism control system to control the material-picking slide cylinder 23 and the material-picking claw cylinder 24 to perform corresponding actions, that is, one set of slide cylinders and material-picking claw cylinders 24 near the material-picking station performs the material-picking action, and the other set of slide cylinders and material-picking claw cylinders 24 performs the material-feeding action.

[0029] Optionally, the material handling gear 22 is provided with a second mounting bracket 8, and the second mounting bracket 8 is provided with an electrical slip ring 9. The conductive slip ring can solve the problem of wire entanglement during the 360-degree rotation of the material handling assembly 2, and realize the electrical connection between the fixed part and the rotating part, so as to ensure that the material handling assembly 2 can stably obtain the required power and signal during operation.
