Description

TECHNICAL FIELD

[0001] The utility model relates to the field of battery manufacturing and transportation, and particularly relates to a square case battery PP film pasting carrying tray. BACKGROUND

[0002] In the production process of square case batteries, the bare battery cell usually needs to be treated by pasting a PP film before being put into the case. Because the battery cell is subjected to certain mechanical stress due to assembly pressure and transportation vibration during assembly, the pasted PP film can absorb the impact and protect the internal structure of the battery cell from being damaged by virtue of its flexibility and elasticity. Meanwhile, the smooth surface of the PP film can effectively reduce the friction between the battery cell and the metal case and prevent the battery cell surface coating or diaphragm from being scratched, thereby eliminating the safety hazard. However, the bare battery cell is composed of multiple single battery cells by welding, and is relatively thick and heavy. In the traditional process, a plastic suction tray is used as a transfer tool before the battery cell is pasted with the film, but such a tray has serious defects in actual application:

[0003] 1. Structural fragility: the traditional plastic suction tray is prone to blockage rupture when facing the inertial force of the wire harness in the battery cell.

[0004] 2. Safety hazard: once the tray blockage is broken, the battery cell may be punctured, causing damage to the battery cell and thus quality problems and economic losses in subsequent production links.

[0005] The above problems urgently require improvement of the existing tray structure to develop a carrying tray with higher mechanical strength and safety and reliability, which can not only meet the transportation needs before and after the battery cell is pasted with the PP film, but also effectively absorb the impact force in the transportation process to avoid damage to the battery cell caused by tray breakage. UTILITY MODEL CONTENTS

[0006] In view of the problem that the traditional plastic suction tray is damaged due to wire harness inertia during transportation and thus damages the battery cell, the utility model aims to provide a square case battery PP film pasting carrying tray, which improves the safety and stability of the battery cell during transportation and reduces the production cost by using ABS+glass fiber composite material and optimizing the structure design.

[0007] In order to achieve the above purpose, the utility model is implemented by the following technical scheme: a square case battery PP film pasting carrying tray, comprising a tray for carrying the battery cell, a bottom plate for fixing the tray, and a metal sensing assembly, the metal sensing assembly is arranged at the bottom of the tray, the tray is provided with a limiting groove for the battery cell, two opposite sides of the limiting groove are provided with a mechanical hand avoidance groove, and the other two opposite sides are respectively provided with a tray information coding and a snapshot avoidance position.

[0008] As a preferred, the center of the limiting groove is provided with a light hole.

[0009] Preferably, the bottom of the tray is in a hollow structure, and is provided with a metal sensor mounting hole and a guide hole.

[0010] Preferably, the bottom of the tray is in a hollow structure, and is provided with a metal sensor mounting hole and a guide hole.

[0011] Preferably, the thickness of the tray and the bottom plate is not less than 3mm.

[0012] The utility model discloses the beneficial effect that the structure design of the utility model is reasonable, adopts ABS + glass fiber composite material to make tray main part, and this material not only has high strength, and has excellent impact resistance and toughness. Effectively solved the problem that the traditional plastic uptake tray is damaged in the transportation process because of the inertia of the wire harness and breaks the block. The tray not only improves the safety and stability in the transportation process of the electric core, but also reduces the production cost, has wide application prospect and popularization value.

[0017] Refer to Figs. 1-2 , the specific embodiment adopts the following technical scheme: a square shell battery pastes PP film carrying tray, including the tray 1 of bearing electric core, the bottom plate 2 of fixed tray and metal induction assembly 3, metal induction assembly 3 sets up at the bottom of tray 1, the tray 1 is provided with the limiting slot 5 of electric core 4, and the two sides of limiting slot 5 are provided with mechanical hand empty slot 6, and the other two sides are provided with tray information coding 7 and snapshot empty position 8 respectively.

[0018] It is worth noting that the center of the limiting slot 5 is provided with a light hole 9.

[0019] It is worth noting that the bottom of the tray 1 is in a hollow structure, and is provided with a metal sensor mounting hole 10 and a guide hole 11.

[0020] It is worth noting that the bottom of the tray 1 is provided with positioning holes 12 fixed with the conveying line, and the bottom plate connecting holes 13 on the tray 1 are fixed with the bottom plate 2 through screws.

[0021] In addition, the tray 1 and the bottom plate 2 are both made of ABS+glass fiber material through injection molding process, and the tray and the bottom plate can achieve long service life and recycling requirements by using a thickness of 3mm.

[0022] The tray of the embodiment is provided with a bare cell limiting groove, a single-side reserved gap of 1.5mm, and prevents the cell from shaking and colliding in the carrying process to cause poor positioning of the PP film mechanical hand. The tray is provided with a mechanical hand avoidance groove, a light hole for detecting whether the tray carries the cell, and a two-dimensional code detection channel for recording the current information of the battery.
