A sagger transport device for lithium battery positive and negative electrode powders

Abstract

The present invention proposes a sagger transport device for lithium battery positive and negative electrode powder. Through the cooperation of a clamping mechanism and a conveying mechanism, a group of unloaded second sagger groups is transported to the lower part of the unloading mechanism for loading. After the loading is completed, another group of unloaded second sagger groups is transported to the lower part of the unloading mechanism through the clamping mechanism. The original second sagger group is pushed to the output end by the thrust of the unloaded second sagger group. No other auxiliary output device is required, so the efficiency is increased. At the same time, compared with the original roller or ceramic wheel transportation, the speed of transportation using the clamping mechanism is increased from 6m / min to 20m / min, which is efficient, fast and simple to operate.

Description

Technical Field

[0001] The present invention relates to the technical field of lithium-ion battery production equipment, and more specifically to a sagger transport device for lithium battery positive and negative electrode powders. Background Art

[0002] In the production of powder materials such as lithium-ion battery positive electrode materials, the materials to be sintered must first be loaded into a first sagger and then sintered at high temperature in a kiln.

[0003] Existing sagger loading equipment generally adopts the transportation method of rollers or ceramic wheels. Each unloading mechanism corresponds to a first sagger. After the material enters the first sagger from the feeding device, it directly enters the first sagger from the discharge port to complete the loading action. After the loading is completed, it is transported to the kiln by rollers or ceramic wheels for high-temperature sintering.

[0004] The existing patent CN107933982A, an automatic bowl loading machine and a bowl loading method thereof, the loading conveyor line is installed on the frame through a three-dimensional spatial displacement drive device and can be driven by the three-dimensional spatial displacement drive device for horizontal and vertical translation movement, a feeding device is installed above the loading conveyor line for unloading the material by relying on the dead weight of the material, the feeding device has a feeding head that can be extended into the sagger, the lower end face of the feeding head is parallel to the horizontal plane, and the lower end face of the feeding head is provided with one or more discharge ports for outputting the material from the feeding device, the frame is installed with a bowl feeding conveyor line for docking with the input end of the loading conveyor line and a bowl discharging conveyor line for docking with the output end of the loading conveyor line.

[0005] However, the conveying method of the roller or ceramic wheel is slow. At the same time, if the feed conveyor line and the bowl conveyor line on the left and right ends of the connector need to be driven and connected by a drive device, automatic discharge cannot be achieved, and the overall speed will drop a lot.

[0006] In view of this, the present invention proposes a sagger transport device for lithium battery positive and negative electrode powders that is efficient, fast, and easy to operate. Summary of the Invention

[0007] In view of this, in order to solve the problem that the existing conveying method of rollers or ceramic wheels is slow, and if the feeding conveying line and the bowl conveying line at the left and right ends of the connector need to be driven and connected by a driving device, and automatic discharging cannot be achieved, the overall rate will drop a lot, the present invention proposes a sagger transportation device for positive and negative electrode powder of lithium batteries. Through the cooperation of the clamping mechanism 40 and the conveying mechanism 50, a group of unloaded second sagger groups are transported to the lower part of the unloading mechanism for loading. After the loading is completed, another group of unloaded second sagger groups are transported to the lower part of the unloading mechanism through the clamping mechanism 40. The original second sagger group is pushed to the output end by the thrust of the unloaded second sagger group. No other auxiliary output device is required, and the efficiency is increased. At the same time, the speed of the clamping mechanism transportation is increased from 6m / min to 20m / min compared with the original roller or ceramic wheel transportation, which is efficient, fast and simple to operate.

[0011] Furthermore, the third connecting arm 45 is connected to the cylinder shaft of the power drive device 41 through a first sliding mechanism 46. At the same time, the bottom of the first sliding mechanism 46 is fixed on the first mounting frame 42.

[0012] Furthermore, the first sliding mechanism 46 includes a first slider 47 and a first slide rail 48. The first slider 47 and the first slide rail 48 are matched and connected. The first slide rail 48 is fixedly mounted on the first mounting frame 42.

[0013] Furthermore, a clamping wheel 49 is provided at the contact end of the first connecting arm 43 with the second sagger 30 . Since the second sagger 30 is relatively fragile, the clamping wheel 49 can better protect the body of the second sagger 30 while ensuring the clamping force.

[0014] Furthermore, the outside of the clamping wheel 49 is covered with a non-metallic soft elastic material, preferably silicone or PU glue. The clamping wheel 49 of the clamping mechanism 40 is made of flexible material, and the impact force is effectively buffered, so that the powder loaded in the sagger is not easily shaken off to the outside, and the sagger is protected.

The linear sliding guide mechanism 52 is provided with a pulley 55 on the plane near its four corners, and the two pulleys 55 at the corresponding corners are vertically arranged, so that the linear sliding guide mechanism 52 and the pulley mechanism 53 are indirectly limited, so that the pulley mechanism 53 is not easy to fall off from the linear sliding guide mechanism 52.

[0018] Furthermore, the upper or lower part of the pulley mechanism 53 is connected to a transport mechanism 56 , and the transport mechanism 56 includes a belt 57 and a belt driving mechanism 58 . The belt driving mechanism 58 is connected to the belt 57 to drive the belt 57 to move back and forth. The belt 57 is fixedly connected to the pulley mechanism 53 .

[0019] In some embodiments, a first sagger group 67 is provided on one side of the second sagger group, and a third sagger group 31 is provided on the other side. The number of saggers in the first sagger group 67, the second sagger group, and the third sagger group 31 is the same, and the first sagger group 67, the second sagger group, and the third sagger group 31 can be converted into each other. The second sagger group is used to receive the positive and negative electrode powder of the lithium battery dropped by the unloading mechanism. The first sagger group 67 is an empty sagger group, which is used to move to the lower part of the unloading mechanism through the clamping mechanism 40. The third sagger group 31 is an output sagger group, which is used to output the positive and negative electrode powder of the lithium battery. The saggers are transported to the next process, and the movement principle is: the clamping structure transports a group of first sagger groups 67 to the bottom of the unloading mechanism and is filled with the positive and negative electrode powder of the lithium battery, which is the second sagger group; the clamping structure returns and transports another group of first sagger groups 67 to the bottom of the unloading mechanism and is filled with the positive and negative electrode powder of the lithium battery; at the same time, relying on the thrust of the other group of first sagger groups 67, the front group of second sagger groups is automatically pushed to the output and becomes the third sagger group 31, so that there is no need to install a sagger transportation mechanism between the second sagger group and the third sagger group 31, which saves costs and improves efficiency.

[0020] Furthermore, a first auxiliary drive device 32 is provided below the first sagger group 67 and / or the third sagger group 31.

A lifting drive mechanism 63 is provided at the lower part of the second auxiliary drive device body 61. When the first sagger group 67 and / or the third sagger group 31 needs to be moved, the lifting drive mechanism 63 moves upward, so that the wear-resistant sliding component 62 contacts the bottom of the first sagger group 67 and moves with the movement of the first sagger group 67 and / or the third sagger group 31.

[0024] Furthermore, the wear-resistant sliding assembly 62 is a plurality of driven wheels, and the rotation direction of the driven wheels is the same as the movement direction of the first sagger group 67 and / or the third sagger group 31. A lifting drive mechanism 63 is provided at the lower part of the second auxiliary drive device body 61.

At the same time, when the jacking drive mechanism 63 moves upward to the top, the wear-resistant sliding assembly 62 is lifted above the ceramic wheel group 33 and moves with the movement of the first sagger group 67.
