Description

Technical Field

[0001] This invention relates to the field of lithium battery manufacturing, and in particular to a cylindrical battery material transfer speed change device used in formation and capacity testing equipment. Background Technology

[0002] In the current process of producing cylindrical lithium batteries, there are two material transport methods for the battery appearance inspection: intermittent and continuous, after the cylindrical surface inspection is completed. Intermittent transport typically uses a conveyor belt to transport the battery to the inspection station, then stops to wait for the camera to finish inspection before resuming transport. While this intermittent transport and inspection method meets functional requirements, its low efficiency affects the overall system cycle time, and the constant start-stop cycles significantly impact the equipment's lifespan. To improve the cycle time, the number of photography stations needs to be increased, indirectly increasing maintenance costs. In the context of manufacturing automation, achieving automation while improving equipment efficiency and accuracy and controlling maintenance costs is imperative. This places demands on the mechanized and intelligent handling, transport, and inspection speed of batteries. Therefore, a continuous variable-speed transport method is needed, i.e., one set of uniform-speed feeding at the inlet and multiple sets of variable-speed discharge at the outlet, to improve efficiency and simultaneously ensure static photography of the material during end-face inspection, thereby achieving high inspection accuracy. Summary of the Invention

[0003] To address the above problems, this invention proposes a cylindrical battery material transfer speed change device.

[0004] A cylindrical battery material transfer and speed-changing device includes a horizontal rectangular base. The base has two horizontal long sides (left and right) and two short sides (front and rear). A vertical first side plate is connected to the right side of the base, and this first side plate is connected to a fork mounting plate on the upper surface of the base. A second side plate, parallel to the first side plate, is fixedly connected to the right side of the first side plate via a discharge fork. A first, second, third, and fourth rotating shaft are mounted on the first side plate along a left-right direction via bearings. The first and fourth rotating shafts pass through the base. A first gear is connected to the left side of the first rotating shaft, a second gear to the left side of the second rotating shaft, a third gear to the left side of the third rotating shaft, and a fourth gear to the left side of the fourth rotating shaft. A fourth gear is connected to the left side of the shaft; the first and second rotating shafts are fixedly connected by a first swing arm to fix the center distance between the first and second gears, so that the first and second gears mesh; the second and third rotating shafts are fixedly connected by a connecting rod, and the distance between the second and third gears is close to meshing; the third and fourth rotating shafts are fixedly connected by a second swing arm to fix the center distance between the third and fourth gears, so that the third and fourth gears mesh; an eccentric shaft rotatably connected to the second side plate is provided through the base of the mechanism, and a fifth gear is sleeved on the eccentric shaft. The side of the fifth gear is provided with a protruding shaft offset from the eccentric shaft, and the protruding shaft is connected to the third rotating shaft through a pull rod; the fifth gear and the first gear mesh by fixing the center distance through the base of the mechanism.

[0005] The first rotating shaft on the right side of the first side plate is fixedly connected to the first buffer wheel, the second rotating shaft is connected to the second buffer wheel, the third rotating shaft is connected to the third buffer wheel, and the fourth rotating shaft is connected to the fourth buffer wheel. The first, second, third, and fourth buffer wheels are all provided with grooves for adsorbing and gripping battery materials. The first buffer wheel is provided with a first buffer fork. The first buffer fork is fixedly connected to the first swing arm and can guide and limit the movement of batteries between the first and second buffer wheels. The second buffer wheel is provided with a second buffer fork, which is fixedly connected to a connecting rod and is used for guiding and limiting the movement of batteries between the second and third buffer wheels. The third buffer wheel is provided with a third buffer fork, which is fixedly connected to the second swing arm and is used for guiding and limiting the movement of batteries between the third and fourth buffer wheels.

[0006] More specifically, a first keyless expansion sleeve connects the second shaft and the second gear, a second keyless expansion sleeve connects the third shaft and the third gear, and the fourth shaft and the fourth gear are connected via a third keyless expansion sleeve.

[0007] During operation, the external cylindrical battery cell material is fed from the first buffer wheel, and through rotation, it is sequentially gripped to the second buffer wheel, the third buffer wheel, and finally discharged from the fourth buffer wheel. The eccentric shaft can pull the third rotating shaft to realize the displacement of the third gear and the second gear, change the meshing tightness between the second gear and the third gear, and thus change the gear speed, completing the relative speed change between the first buffer wheel, the second buffer wheel, the third buffer wheel and the fourth buffer wheel. This achieves the effect of feeding one group of cylindrical battery cells at a time to the first buffer wheel, and discharging multiple groups of cylindrical battery cells from the fourth buffer wheel.

[0008] The advantages of this invention are that it achieves variable speed discharge while maintaining uniform feeding speed through the combination of buffer wheel and four-bar structure. During the material conveying process, the front-end material is fed continuously, reducing the need for start-stop operations. This improves the detection efficiency and accuracy of the rear appearance inspection equipment while reducing the influence between the appearance inspection speed and the front-end feeding speed, thereby improving the work efficiency of appearance inspection and the cycle time of the overall system, and improving the production efficiency of battery inspection.

The discharge fork 5 can discharge the cylindrical battery material. A first rotating shaft 102, a second rotating shaft 106, a third rotating shaft 112, and a fourth rotating shaft 116 are passed through the first side plate along the left-right direction via bearings. The first rotating shaft 102 and the fourth rotating shaft 116 are connected to the base. A first gear 103 is connected to the left side of the first rotating shaft 102, a second gear 105 is connected to the left side of the second rotating shaft 106, and a third rotating shaft 112 is connected to the left side of the third rotating shaft 112. The third gear 110 is connected to the side, and the fourth gear 118 is connected to the left side of the fourth shaft 116. The first shaft 102 and the second shaft 106 are fixedly connected by the first swing arm 104 to fix the center distance between the first gear 103 and the second gear 105, so that the first gear meshes with the second gear. The third shaft is fixedly connected to the second shaft by a connecting rod. The third shaft 112 and the fourth shaft are fixedly connected by the second swing arm 109 through the 116, so as to fix the center distance between the third gear 110 and the fourth gear 118, so that the third gear 110 meshes with the fourth gear 118. The mechanism base is provided with an eccentric shaft 114 that connects to the first side plate. The eccentric shaft is fitted with a fifth gear 115. The fifth gear 115 has a protruding shaft on its side that deviates from the eccentric shaft. The protruding shaft is connected to the third shaft 112 through a pull rod 113. The fifth gear 115 and the first gear 103 mesh by fixing the center distance through the mechanism base 101.

[0021] The first rotating shaft 102 on the right side of the first side plate is fixedly connected to the first buffer wheel 201, the second rotating shaft 106 is connected to the second buffer wheel 203, the third rotating shaft 112 is connected to the third buffer wheel 205, and the fourth rotating shaft 116 is connected to the fourth buffer wheel 207; the first, second, third, and fourth buffer wheels are all provided with grooves for adsorbing and gripping battery materials; the first buffer wheel 201 is provided with a first buffer fork 202, the second buffer wheel 203 is provided with a second buffer fork 204, and the third buffer wheel 205 is provided with a third buffer fork. Fork 206; First buffer fork 202 is fixedly connected to first swing arm 104 and can guide and limit the movement during the process of conveying batteries between first buffer wheel and second buffer wheel; Second buffer fork 204 is fixedly connected to connecting rod 108 and is used for guiding and limiting the movement during the process of conveying batteries between second buffer wheel 203 and third buffer wheel 205; Third buffer wheel 205 can grab cylindrical battery material and convey it to fourth buffer wheel 207; Third buffer fork 206 is fixedly connected to second swing arm 109 and is used for guiding and limiting the movement during the process of conveying batteries between third buffer wheel and fourth buffer wheel.

[0023] During operation, the external cylindrical battery cell material is fed from the first buffer wheel 201, and is sequentially gripped by the second buffer wheel 203, the third buffer wheel 205, and finally discharged by the fourth buffer wheel 207. The eccentric shaft can pull the third rotating shaft 112 to realize the relative displacement of the third gear 110 and the second gear 105, periodically changing the meshing tightness between the second gear 105 and the third gear 110, thereby changing the gear speed and completing the relative speed change between the first buffer wheel 201, the second buffer wheel 203, the third buffer wheel 205 and the fourth buffer wheel 207.

This improves the detection efficiency and accuracy of the rear appearance inspection equipment while reducing the influence between the appearance inspection speed and the front-end feeding speed, thereby improving the work efficiency of appearance inspection and the cycle time of the overall system, and improving the production efficiency of battery inspection.
