Description

Technical Field

[0001] This utility model belongs to the technical field of new energy lithium battery production equipment, specifically relating to a transmission device for coating new energy lithium batteries. Background Technology

[0002] In the production process of new energy lithium batteries, cell coating is a core process to ensure battery safety (preventing short circuits) and structural stability. The transmission efficiency and positioning accuracy of the cells before and after coating directly determine the overall production cycle and coating quality. Currently, mainstream lithium battery coating transmission devices on the market generally suffer from the following technical defects:

[0003] 1. Poor process coordination: The loading module, coating station, and unloading module rely on independent handling mechanisms. They can only start the next process (such as station placement) after the previous process (such as loading) is completed. This makes it impossible to achieve synchronous "loading-station placement-unloading", resulting in slow production cycle and low transmission efficiency.

[0004] 2. Insufficient stability of movement: The horizontal movement and vertical lifting of the handling mechanism are mostly guided by a single rail or without an auxiliary guiding structure. Uneven force can easily cause the battery cell to shift or even cause the battery cell to be damaged by impact (the outer shell of the lithium battery cell is thin and easily deformed).

[0005] Therefore, further improvements will be made to address the aforementioned issues. Utility Model Content

[0006] The main purpose of this utility model is to provide a transmission device for coating new energy lithium batteries, which has the advantages of realizing simultaneous operation of multiple processes, stable movement, high precision and high reliability, so as to meet the needs of large-scale production of lithium batteries.

[0007] To achieve the above objectives, this utility model provides a transmission device for encapsulating new energy lithium batteries, comprising a feeding module, a discharging module, and a conveying module, wherein the feeding module and the discharging module are respectively located on both sides of the conveying module, wherein:

[0008] Both the feeding module and the unloading module are equipped with a base frame, a top frame, a motor, a first roller, a second roller, and a conveyor belt.

The drive end of the motor is connected to one end of the first roller, and the conveyor belt is installed between the first roller and the second roller.

[0009] The conveying module includes a main frame, a driver, a first drive plate, a vertical cylinder, a first slide rail assembly, a second slide rail assembly, a second drive plate, a mounting frame, and several adsorption units. The driver is mounted on the main frame, and the first drive plate is connected to the drive end of the driver.

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0024] This utility model discloses a transmission device for coating new energy lithium batteries. The specific embodiments of the utility model are further described below with reference to preferred embodiments.

[0025] In the embodiments of this utility model, those skilled in the art will note that the battery cells and the like involved in this utility model can be considered as prior art.

[0026] Preferred embodiment.

[0027] like Figure 1-3 As shown, this utility model discloses a transmission device for encapsulating new energy lithium batteries, including a feeding module 10, a discharging module 20, and a conveying module 30. The feeding module 10 and the discharging module 20 are respectively located on both sides of the conveying module 30, wherein:

[0028] Both the feeding module 10 and the unloading module 20 are equipped with a base frame 11, a top frame 12, a motor 13, a first roller 14, a second roller 15, and a conveyor belt 16. The top frame 12 is fixedly installed on the top of the base frame 11. The motor 13 is fixedly installed on the base frame 11, and the first roller 14 and the second roller 15 are respectively installed at both ends of the top frame 12. The drive end of the motor 13 (through a transmission structure such as rollers and belts) is connected to one end of the first roller 14. The conveyor belt 16 is installed between the first roller 14 and the second roller 15 (the motor drives the first / second rollers and the conveyor belt to rotate, thereby completing the feeding and unloading of the battery cells 40).

[0029] The conveying module 30 includes a main frame 31, a driver 32 (for horizontal movement, including a motor, screw, and slider), a first drive plate 33, a vertical cylinder 34, a first slide rail assembly 35, a second slide rail assembly 36, a second drive plate 37, a mounting frame 38, and several adsorption units (including adsorption cylinders and suction cups). The driver 32 is mounted on the main frame 31, and the first drive plate 33 is connected to the drive end of the driver 32 (the driver enables horizontal movement of the first drive plate). The vertical cylinder 34, the first slide rail assembly 35, and the second slide rail assembly 36 are all mounted on the first drive plate 33. The second drive plate 37 is mounted between the first slide rail assembly 35 and the second slide rail assembly 36, and the second drive plate 37 is connected to the drive end of the vertical cylinder 34 (the vertical cylinder drives the second drive plate to move vertically on the first / second slide rail assembly). The mounting frame 38 is fixedly mounted on the bottom of the second drive plate 37, and the adsorption units are mounted on the mounting frame 38.

[0030] Specifically, the adsorption unit includes a first adsorption unit 391, a second adsorption unit 392, a third adsorption unit 393, and a fourth adsorption unit 394 arranged from the feeding module 10 to the unloading module 20. A first coating station 395 and a second coating station 396 are provided between the feeding module 10 and the unloading module 20. (During transmission, the driver is first activated, moving the first drive plate, mounting bracket, and adsorption units towards the feeding module, so that the first / second adsorption units are above the feeding module, the third adsorption unit is above the first coating station, and the fourth adsorption unit is above the second coating station. Then, the vertical cylinder is activated, causing the second drive plate to move downwards and cooperate with the adsorption units, so that the first / second adsorption units grasp the battery cell 40 to be coated located on the feeding module.) The third / fourth adsorption unit picks up the battery cell 40 that has already been coated at the first / second coating station. Then, the vertical cylinder is activated again, causing the second drive plate to move up a certain distance. Then, the driver is activated again, moving the first drive plate, mounting bracket, and adsorption unit towards the feeding module, so that the first / second adsorption unit is above the first / second coating station, and the third / fourth adsorption unit is above the feeding module. Then, in conjunction with the vertical cylinder and adsorption unit, the battery cell picked up by the first / second adsorption unit is placed on the first / second coating station for subsequent coating. The completed battery cell picked up by the third / fourth adsorption unit is placed on the conveyor belt of the feeding module, thus completing the feeding. The above work is repeated to complete the feeding, coating station placement, and feeding simultaneously, improving the transmission efficiency.

[0031] More specifically, the first drive plate 33 is provided with an upper limit block 331 and a lower limit block 332, and the second drive plate 37 is provided with a stop block 371. The stop block 371 is located between the upper limit block 331 and the lower limit block 332 (when the second drive plate moves vertically relative to the first drive plate under the drive of the vertical cylinder, the upper limit block, the lower limit block and the stop block cooperate to prevent the second drive plate from moving excessively).

[0032] Furthermore, the main frame 31 is provided with a third slide rail assembly 311 and a fourth slide rail assembly 312, and the first drive plate 33 is installed between the third slide rail assembly 311 and the fourth slide rail assembly 312 (making the first drive plate more stable when moving horizontally).

[0033] Furthermore, the transport module 30 also includes a position sensor 313 (to make the movement of the adsorption unit and the adsorption and transport of the battery cell more precise).

[0034] The working process of this utility model is as follows:

[0035] 1. Initial positioning: After the equipment is started, the driver drives the first drive board to move to the left until the first adsorption unit and the second adsorption unit are aligned with the two battery cells to be coated on the conveyor belt of the feeding module, the third adsorption unit is aligned with the first coating station, and the fourth adsorption unit is aligned with the second coating station (the position is confirmed by the position sensor).

[0036] 2. Adsorption of battery cells: The vertical cylinder extends, driving the second drive plate, mounting bracket and adsorption unit to move down, stopping when the lower limit block contacts the stop block; after the adsorption cylinder extends and the suction cup contacts the battery cell, the negative pressure system is activated, the suction cup adsorbs the battery cell to be coated, and at the same time the third / fourth adsorption unit adsorbs the battery cells that have been coated at the first / second coating station;

[0037] 3. Lifting and Transfer: The adsorption cylinder shortens (slightly moving the battery cell upward to avoid friction), then the vertical cylinder shortens, moving the second drive plate upward, stopping when the stop block contacts the upper limit block;

[0038] 4. Synchronous placement: The driver drives the first drive board to move to the right (the distance between two adsorption units) until the first adsorption unit aligns with the first coating station, the second adsorption unit aligns with the second coating station, and the third and fourth adsorption units align with the conveyor belt of the unloading module (the position is confirmed by the position sensor).

[0039] 5. Releasing the battery cell: After the vertical cylinder extends and the suction cup contacts the positioning groove / transfer belt, the negative pressure system is shut off, and the suction cup releases the battery cell (the battery cell to be coated falls into the coating station, and the coated battery cell falls into the unloading module).

[0040] 6. Cyclic Reset: The vertical cylinder shortens and resets, and the driver drives the first drive plate to move to the left to reset, entering the next working cycle. At the same time, the feeding module motor starts and transfers the glued battery cells to the next process.

[0041] It is worth mentioning that the technical features such as the battery cell involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent.
