Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing, in particular to a sorting machine for lithium battery processing. Background Art

[0002] In the lithium battery production process, due to the influence of various factors, there will be certain differences in the performance parameters of the battery, such as size, quality, internal resistance, etc., so they need to be sorted to ensure the consistency of product quality and performance. When sorting unqualified lithium batteries, the existing sorting equipment generally first transports the lithium batteries to a carrier plate equipped with a gravity sensor through a conveying device, and the quality of the lithium battery is displayed through the signal sent by the gravity sensor. However, during the lithium battery sorting process, the lithium battery will hit the carrier plate with the sensor many times, and the gravity sensor is a high-precision device. Frequent collisions will increase the probability of failure and affect the equipment's sorting of lithium batteries. In view of this, we propose a sorting machine for lithium battery processing. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Unqualified lithium battery quality may reduce the performance of lithium batteries and increase their safety risks. Therefore, after the lithium battery processing is completed, its quality will be measured. The existing lithium battery quality-based sorting equipment mainly measures the quality of lithium batteries through gravity sensors. However, the impact force caused by the lithium battery falling on the supporting equipment equipped with gravity sensors may reduce the sensitivity of the gravity sensor, thereby affecting the sorting of lithium batteries. In view of the above defects, we proposed the following solution:

[0020] Embodiment 1

[0021] After repeated use, the existing lithium battery processing sorting machine may have inaccurate lithium battery quality measurement, resulting in poor lithium battery sorting effect. Figure 1-Figure 3 This embodiment proposes a sorting machine for lithium battery processing, which realizes the sorting of lithium batteries of different qualities. Compared with the traditional sorting method, it avoids the situation that the sorting effect will be reduced after multiple sorting. It is mainly composed of two anti-flying brackets 1, and a screening component 3 for sorting lithium batteries is arranged between the two anti-flying brackets 1. A conveying structure 2 for intermittently conveying lithium batteries is arranged at one end of the anti-flying bracket 1. During sorting, the lithium batteries can be intermittently conveyed between the anti-flying brackets 1 through the conveying structure 2, and the sorting operation is performed through the screening component 3 arranged between the two anti-flying brackets 1.

[0022] In order to solve the risk that the sorting effect of the existing sorting equipment will be reduced after multiple sorting, this embodiment reduces the setting of the gravity sensor through the setting of the screening component 3, and uses the inertia of lithium batteries of different masses to achieve the sorting of lithium batteries, such as Figure 2 As shown, the screening component 3 includes a screening chute 31 arranged between two anti-flying brackets 1, the screening chute 31 is provided with an acceleration section 3101 and a screening section 3102, and the screening section 3102 is provided with two separation lines 32, the screening section 3102 is divided into an overweight area, a qualified area and a lighter area in order from left to right, and a buffer component 35 for buffering the impact force of the lithium battery is provided at the rightmost end of the acceleration section 3101. Because the conveying structure 2 runs at a uniform speed, each lithium battery that flies out has the same initial velocity and the same height of the throwing point, so the horizontal throwing distance is also similar. Therefore, the lithium batteries thrown from the conveying structure 2 will all fall on the buffer component 35, and after being buffered by the buffer component 35, they will fall on the acceleration section 3101, as shown in FIG. Figure 2As shown, the acceleration section 3101 is tilted, so the lithium battery that falls into the acceleration section 3101 will slide downward at an accelerated speed under the action of its own gravity until it slides to the screening section 3102, and will continue to move forward under the action of inertia until it stops. Because the mass of an object is a measure of its inertia, the inertia of lithium batteries of different masses will not be the same, so that the areas where they stay on the screening section 3102 are also different. The heavier ones will be in the overweight area, the qualified ones in the qualified area, and the lighter ones in the lighter area. In this way, the separation of lithium batteries of different masses is completed. At this time, the staff can put the lithium batteries of different masses into the corresponding collection equipment, thereby completing the sorting of the lithium batteries.

[0023] The lithium battery thrown from the conveying structure 2 will be subjected to an impact force when it falls on the screening chute 31, which may affect the performance of the lithium battery. In this embodiment, the impact force on the lithium battery is alleviated by the setting of the buffer component 35. Figure 3 As shown, the buffer assembly 35 includes a buffer plate 351 arranged above the acceleration section 3101, a bearing plate 352 is rotatably installed on the upper part of the buffer plate 351, a plurality of sliding rods 353 slidably connected to the acceleration section 3101 are arranged at the lower part of the buffer plate 351, a buffer spring 354 is wound around the outside of the sliding rod 353, and the two ends of the buffer spring 354 are respectively fixed to the acceleration section 3101 and the buffer plate 351, a flip protrusion 355 is arranged on one side of the bearing plate 352, and a resisting rod 356 that resists the flip protrusion 355 is arranged on the acceleration section 3101. In this embodiment, the buffer plate 351 is provided so that the buffer spring 354 will absorb the impact force of the lithium battery by contraction when the lithium battery falls onto the supporting plate 352, thereby protecting the lithium battery. In addition, during the contraction of the buffer spring 354, the buffer plate 351 will move downward to unload the force. During the movement, the abutment rod 356 will drive the supporting plate 352 to rotate a certain angle by abutting the flip protrusion 355, so that the lithium battery on the supporting plate 352 will slide onto the acceleration section 3101 under the action of its own gravity.

[0024] The supporting plate 352 is hollow in design and has certain deformation performance. After the lithium battery falls, the supporting plate 352 will shrink inward by a certain distance, thereby achieving the effect of alleviating the impact force of the lithium battery.

[0025] Embodiment 2

[0026] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the shortcomings of the existing lithium battery processing sorting machine that may cause inaccurate lithium battery quality measurement after repeated use, resulting in poor lithium battery sorting effect. However, lithium batteries with similar quality differences are driven by a relatively small initial velocity and their positions on the screening section 3102 are also similar, which can easily affect the screening of lithium batteries.

[0027] Reference Figure 1-Figure 3 A plurality of friction-reducing balls 34 are provided on the acceleration section 3101. In this embodiment, the distance between the lithium battery and the acceleration section 3101 is converted from sliding friction to rolling friction through the provision of the friction-reducing balls 34. The friction resistance between the lithium battery and the acceleration section 3101 is reduced by reducing the friction coefficient, so that the lithium battery has a greater initial velocity when sliding into the screening section 3102. According to the kinetic energy theorem, the greater the initial velocity, the longer the distance the object slides under the action of inertia. Therefore, the distance difference between lithium batteries with different inertia will also increase, thereby making it easier to distinguish between lithium batteries of different qualities.

[0028] When lithium batteries are subjected to some large impacts, there is a risk of explosion, especially some unqualified lithium batteries, which have a higher risk of explosion. Those overweight lithium batteries have a large inertia, so they are easy to slide out of the screening chute 31. In this embodiment, an anti-flying protrusion 33 is provided in the overweight area to prevent the lithium battery from flying out, thereby increasing the resistance of the lithium battery flying out of the screening chute 31 and reducing the probability of it flying out of the screening chute 31.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
