Description

Technical Field

[0001] This utility model relates to the field of conveying technology, specifically to a storage and conveying device for battery cells. Background Technology

[0002] In the lithium battery production process, electrodes and separators need to be cut and stacked. The speed of cutting and stacking directly determines the overall production capacity and the cost of cell manufacturing. Therefore, existing technologies integrate cutting and stacking equipment into a single cutting and stacking machine to simplify the transfer between equipment, meet production needs, and increase production capacity.

[0003] Cutting and stacking machines typically store the finished battery cells on a testing platform. When the required quantity is reached, a robotic arm removes the stacked cells and, in conjunction with a conveyor, delivers them to the packaging and assembly station. However, as the production capacity of cutting and stacking machines increases, the clamping, lifting, and swinging conveying methods of the robotic arm, with their reciprocating motions, are inefficient and time-consuming, making it difficult to meet the demands of high-frequency transportation and transfer.

[0004] Therefore, in order to solve the above problems, a storage and transportation device for battery cells is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a storage and transportation device for battery cells, which can quickly transfer and transport battery cells, thereby solving the problems mentioned in the background art.

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

[0007] A storage and conveying device for battery cells includes a translation module and a conveying mechanism. The translation module is horizontally positioned below one end of the conveying mechanism. A push cylinder is vertically fixed above the platform of the translation module. A guide frame is fixedly mounted on the upper side of the push rod of the push cylinder. A guide groove is horizontally opened at the top of the guide frame. A guide rod is horizontally fixedly mounted inside the guide groove. A guide arm is slidably mounted on the guide rod. The upper and lower sides of the guide arm are slidably assembled with the guide groove. Support frames are fixedly mounted at both ends of the guide arm. A spring is sleeved on the guide rod. The spring abuts against the end of the guide groove away from the conveying mechanism and between the guide arm and the guide groove.

[0008] Specifically, the conveying mechanism includes a speed-regulating motor, synchronous pulleys, and a frame. The number of frames is two arranged side by side and fixed together. Synchronous pulleys are rotatably installed at both ends and the bottom of each frame. A synchronous belt is installed on the synchronous pulleys on the same frame. A speed-regulating motor is installed on the side wall of one of the frames. The output end of the speed-regulating motor is connected to the two synchronous pulleys at the bottom of the frame.

[0009] Furthermore, the width of the guide frame is less than the distance between the two axially aligned synchronous wheels.

[0010] Furthermore, the upper surface of the support frame is flush with the upper surface of the guide frame.

[0011] Furthermore, the upper surfaces of the support frame and guide frame are 2-3 mm lower than the upper surface of the timing belt.

[0012] Specifically, a top block is provided on the upper side of the guide frame away from the conveying mechanism, and the height of the top block is greater than 5mm.

[0013] Specifically, a limit baffle is provided on the upper side of the end of the frame near the guide arm.

[0014] Specifically, the translation module is a magnetically coupled rodless cylinder, and the push cylinder is a thin-type cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] With relatively movable support frames and guide frames, the battery cells produced by the cutting and stacking integrated machine can be stacked and stored. After reaching the set quantity, the translation module and push cylinder work together to send the stored battery cells to the conveying mechanism, which outputs them outwards. After resetting, the storage work is repeated. This alternating operation can meet the needs of efficient and stable transportation and transfer compared to the existing robotic arm transfer method.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a storage and conveying device for battery cells, including a translation module 1 and a conveying mechanism 8. The translation module 1 is horizontally positioned below one end of the conveying mechanism 8. A push cylinder 2 is vertically fixedly installed above the platform of the translation module 1. The translation module 1 is preferably a magnetically coupled rodless cylinder for horizontally reciprocating movement of the push cylinder 2, which has the advantage of saving equipment integration space. Other components that can achieve precise reciprocating motion can also be used without affecting the implementation of this patent. A guide frame 3 is fixedly installed on the upper side of the push rod of the push cylinder 2. The push cylinder 2 is preferably a thin cylinder for vertically reciprocating movement of the guide frame 3, which has the advantages of small space occupation and lightweight structure. Other components that can achieve precise lifting motion can also be used without affecting the implementation of this patent.

[0023] The top of the guide frame 3 has a horizontally opened guide groove, and a guide rod 5 is horizontally fixedly installed inside the guide groove. A guide arm 6 is slidably installed on the guide rod 5. The upper and lower sides of the guide arm 6 are slidably assembled with the guide groove. Support frames are fixedly installed at both ends of the guide arm 6. A spring 7 is sleeved on the guide rod 5. The spring 7 abuts against the end of the guide groove away from the conveying mechanism 8 and the guide arm 6. The spring 7 gives the guide arm 6 a force to move closer to the conveying mechanism 8. The upper surface of the support frame 11 is flush with the upper surface of the guide frame 3 for stable storage of battery cells 10. The number of battery cells 10 stored at one time is 26 to 31.

[0024] Specifically, such as Figure 1 As shown, the conveying mechanism 8 includes a speed-regulating motor 83, synchronous pulleys 81, and a frame 84. There are two frames 84 arranged side by side and fixed together. The frames 84 mainly serve a supporting function. Synchronous pulleys 81 are rotatably mounted at both ends and the bottom of each frame 84. A synchronous belt 82 is mounted on the synchronous pulleys 81 on the same frame 84. A speed-regulating motor 83 is mounted on the side wall of one of the frames 84. The output end of the speed-regulating motor 83 is connected to the two synchronous pulleys 81 at the bottom of the frame 84. The synchronous pulleys 81 at both ends mainly serve a guiding and transmission function to ensure that the upper side of the synchronous belt 82 is in a horizontal position. When the speed-regulating motor 83 is working, it can simultaneously rotate the two synchronous pulleys 81 at the bottom. After the synchronous pulleys 81 at both ends cooperate, the synchronous belt 82 can be driven to perform conveying operations.

[0025] Furthermore, the width of the guide frame 3 is less than the distance between the two axially aligned synchronous pulleys 81, so as to ensure that the guide frame 3 can smoothly enter between the two axially aligned synchronous pulleys 81 and deliver the battery cell 10 to the synchronous pulley 81.

[0026] Furthermore, the upper surfaces of the support frame 11 and the guide frame 3 are 2-3 mm lower than the upper surface of the synchronous belt 82, so that the battery cell 10 can generate sufficient friction when it contacts the synchronous belt 82 due to its own mass, ensuring that the synchronous belt 82 can smoothly transport the battery cell 10 out.

[0027] Furthermore, a top block 4 is provided on the upper side of the guide frame 3 away from the conveying mechanism 8. The height of the top block 4 is greater than 5mm. The top block 4 can always abut against one end of the bottommost battery cell 10 to ensure that the battery cell 10 will not slip when it is fed onto the synchronous belt 82, and the conveying will be completed more smoothly.

[0028] Specifically, a limit baffle 9 is provided on the upper side of the end of the frame 84 near the guide arm 6. The limit baffle 9 is used to ensure the contact area with the guide arm 6, so that the guide arm 6 can be subjected to force more evenly.

[0029] The translation module 1, push cylinder 2, and speed-regulating motor 83 are connected to the electrical control system of the cutting and stacking machine and are uniformly controlled through the controller of the cutting and stacking machine.

[0030] One end of the translation module 1 and the conveying mechanism 8 are installed inside the cutting and stacking machine, while the other end of the conveying mechanism 8 is set with an extension length according to the requirements of the next process.

[0031] The working principle of this embodiment:

[0032] In the initial state, the platform of the translation module 1 is located at the left end station, and the push cylinder 2 is in the downward shortening station. The battery cells 10 produced by the cutting and stacking machine can be stacked on the guide frame 3 and the support frame 11. At the same time, the number of falling battery cells 10 can be monitored by the photoelectric gate component in the cutting and stacking machine.

[0033] When the stacked battery cells 10 reach the set number, the translation module 1 moves the platform to the right to the middle position, and at the same time, the push cylinder 2 completes the lifting of the support frame 11 and the guide frame 3, so that the battery cells 10 are close to the synchronous belt 82.

[0034] Then, the translation module 1 continues to move the platform to the right end station, the guide frame 3 moves into the space between the two synchronous pulleys 81, the support frame 11 is stuck due to the abutment of the guide arm 6 and the limit baffle 9, and at the same time the spring 7 is compressed, and the battery cell 10 can be sent to the synchronous belt 82 through the top block 4.

[0035] The conveying mechanism 8 can efficiently deliver the battery cell 10 to the next process. After the translation module 1 and the push cylinder 2 are reset, the support frame 11 and the guide arm 6 are reset by the elastic force of the spring 7, and the next storage and conveying work can be carried out.
