Description

Technical Field

[0001] The utility model belongs to the technical field of battery trays and relates to a restraint tray for aluminum shell batteries. Background Art

[0002] With the increasing popularity of electric vehicles and the increasing maturity of lithium battery manufacturing technology, the processing of lithium batteries includes main technological processes such as homogenization, coating, rolling, slitting, assembly, and formation and grading. The formation and grading process is an important process, and its main function is to activate the lithium battery and perform capacity detection. The process of lithium battery capacity detection is to batch the batteries into a restraint tray and perform charging and discharging on a charging and discharging device. During the charging and discharging process of the battery, it is necessary to use the restraint tray to clamp the battery to control the thickness of the battery and produce batteries with qualified thickness. The existing restraint tray fixes two guiding shafts on each side of the tray. A restraint slider is sleeved on the guiding shaft, and a through hole for the guiding shaft to pass through is opened on the restraint slider. The aluminum shell battery is clamped between the restraint sliders on both sides. This connection method of the restraint slider makes installation and disassembly very difficult. It is necessary to pull out the entire guiding shaft to remove the restraint slider, resulting in time-consuming maintenance and replacement of the restraint slider. Content of the Utility Model

[0003] The purpose of the utility model is to address the above problems in the existing technology and propose a restraint tray for aluminum shell batteries, which can quickly install and disassemble the restraint slider without removing the guiding shaft and improve the maintenance and replacement speed.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A restraint tray for aluminum shell batteries includes a tray bottom plate, end plates fixed at both ends of the tray bottom plate, and a pressing plate. The feature is that several guiding shafts are fixed between the two end plates. The guiding shafts are arranged in groups of two at intervals, and the two guiding shafts in the same group are arranged vertically. Several restraint sliders are clamped on the guiding shafts. A battery slot for inserting the aluminum shell battery is opened on the front surface of the restraint slider. Two arc-shaped slots that can be clamped on the guiding shaft are opened on the back surface of the restraint slider. One side of the restraint slider has a protruding T-shaped connecting block, and the other side has a T-shaped slot for the T-shaped connecting block on the adjacent restraint slider to be inserted into. The pressing plate is sleeved on the guiding shaft and can translate along the guiding shaft.

[0005] The pressing plate is pushed by an external cylinder to squeeze the restraint sliders together. When disassembling the restraint slider, the cylinder needs to be unloaded, and then each restraint slider can be pulled out horizontally from the guiding shaft. When installing the corresponding restraint slider, only need to push the restraint slider horizontally towards the guiding shaft with force to make the arc-shaped slot clamp the guiding shaft, and the restraint slider can slide along the length direction of the guiding shaft. The aluminum shell battery is inserted between the two restraint sliders from top to bottom, and the end of the aluminum shell battery is embedded in the battery slot. After the aluminum shell battery is firmly clamped by this restraint tray, it is placed on a charging and discharging device for charging and discharging operations.

[0006] Further, a through accommodation hole is formed in the middle of the restraint slider in the transverse direction, and a reinforcing core column is inserted into the accommodation hole. The reinforcing core column is tightly fitted with the accommodation hole. The reinforcing core column is made of hard metal material, and the restraint slider is made of plastic material formed by injection molding. Adding the reinforcing core column can improve the transverse compressive strength of the restraint slider and prevent it from being deformed by the extrusion plate.

[0007] Further, the length of the reinforcing core column is greater than the length of the accommodation hole. When two adjacent restraint sliders are abutted against each other, the reinforcing core columns are abutted against each other prior to other parts, so that most of the transverse extrusion force received by the plastic restraint slider is borne by the reinforcing core columns.

[0008] Further, the front surface of the restraint slider is provided with grid-shaped reinforcing ribs.

[0009] Further, the upper port of the battery slot has a guiding inclined surface for guiding the aluminum shell battery to slide into the slot.

[0010] Compared with the prior art, the restraint tray of this aluminum shell battery has the following advantages:

[0011] 1. A laterally penetrating reinforcing core column is inserted into the middle of the restraint slider, which improves the overall structural strength and is not easily deformed by extrusion.

[0012] 2. An open arc-shaped groove is provided on the back surface of the restraint slider, which can be directly snap-fitted and installed on the guide shaft. The installation and disassembly are both relatively convenient, and there is no need to remove the guide shaft. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0019] The following are specific embodiments of the present utility model and, in conjunction with the attached drawings, the technical solutions of the present utility model will be further described. However, the present utility model is not limited to these embodiments.

[0020] As Figures 1-3 shown, the restraint tray of this aluminum shell battery includes a tray bottom plate 1, end plates 2 fixed at both ends of the tray bottom plate 1, and a pressing plate 3. A number of guide shafts 4 are fixed between the two end plates 2. The guide shafts 4 are arranged at intervals in groups of two. The two guide shafts 4 in the same group are arranged vertically. A number of restraint sliders 5 are clamped on the guide shafts 4.

[0021] As Figures 4-5 shown, a battery slot 51 for inserting the aluminum shell battery is opened on the front surface of the restraint slider 5. Two arc-shaped slots 52 that can be clamped on the guide shafts 4 are opened on the back surface of the restraint slider 5. One side of the restraint slider 5 has a protruding T-shaped connection block 53, and the other side of the restraint slider 5 has a T-shaped slot 54 for the T-shaped connection block 53 on the adjacent restraint slider 5 to be inserted into. The pressing plate 3 is sleeved on the guide shafts 4 and can translate along the guide shafts 4.

[0022] A through accommodation hole is opened in the middle of the restraint slider 5 in the horizontal direction. A reinforcing core column 55 is inserted into the accommodation hole, and the reinforcing core column 55 is tightly fitted with the accommodation hole. The reinforcing core column 55 is made of hard metal material, and the restraint slider 5 is made of plastic material formed by injection molding. Adding the reinforcing core column 55 can improve the horizontal compressive strength of the restraint slider 5 and prevent it from being deformed by the pressing plate 3.

[0023] The length of the reinforcing core column 55 is greater than the length of the accommodation hole. When two adjacent restraint sliders 5 are abutted together, the reinforcing core column 55 abuts together prior to other parts, so that most of the horizontal extrusion force received by the plastic restraint slider 5 is borne by the reinforcing core column 55.

[0024] Grid-shaped reinforcing ribs 56 are provided on the front surface of the restraint slider 5, and a guiding inclined surface 57 for guiding the aluminum shell battery to slide into the slot is provided at the upper port of the battery slot 51.

[0025] Working principle: The pressing plate 3 is pushed by an external cylinder to squeeze the restraint sliders 5 together. When disassembling the restraint sliders 5, the cylinder needs to be unloaded, and then the restraint sliders 5 can be horizontally pulled out from the guide shafts 4 one by one. When installing the corresponding restraint sliders 5, only need to horizontally push the restraint sliders 5 towards the guide shafts 4 with force, so that the arc-shaped slots 52 are clamped on the guide shafts 4, and the restraint sliders 5 can slide along the length direction of the guide shafts 4. The aluminum shell battery is inserted downward between the two restraint sliders 5, and the end of the aluminum shell battery is embedded in the battery slot 51. After the aluminum shell battery is firmly clamped by this restraint tray, it is placed on the charging and discharging equipment for charging and discharging operations.

[0026] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar ways for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
