Problems solved by technology

[0005] 1) When manually dispensing glue, it is difficult to guarantee the effect of dispensing, and it is easy to have glue overflow, glue leakage and other phenomena. The glue is uneven, and the labor intensity of the employees is high, and the production efficiency is low;
[0006] 2) Manual paving of glue lines will inevitably lead to inaccurate alignment. At the same time, due to the varying strength of manual pressing, the bonding effect formed after glue line paving is poor. Once glue leakage occurs, it is easy to cause glue leakage. thread shedding;
[0007] 3) After the dispensing is completed, if the glue line is not paved in time, the glue will dry out. Once the dry glue appears, the bonding strength of the glue line formed is difficult to meet the requirements

Embodiment 1

[0040] Such as figure 1 As shown, the integrated machine for dispensing glue and glue line laying of fuel cell plates in this embodiment includes a frame 1, a transfer unit 2, a glue dispensing unit 3, a glue line laying unit 4, and a plate turning unit F .

[0041] Specifically, the rack 1 includes rack legs 10 and a table top 11 , where the length direction of the table top 11 is defined as the X axis, the width direction is the Y axis, and the height direction is the Z axis.

[0042] In this example, the platform 11 is in the shape of a cuboid, and is horizontally arranged on the legs 10 .

[0043] The transfer unit 2 includes a carrier 20 and a moving carrier 21 arranged on the platform 11 , wherein the moving carrier 21 can relatively move on the carrier 20 along X, Y, and Z axes.

[0044] combine figure 2As shown, the carrier 20 includes a fixed seat 200, a truss rod 201 located on the fixed seat 200, and a sliding seat 202 arranged on the truss rod 201, wherein the ...

Embodiment 2

[0088] The structure of the integrated machine for dispensing and glue line paving used in this embodiment and Embodiment 1 is the same, the difference is that in this embodiment, during the dispensing process, the control of the Z-axis direction ensures that the dispensing head is in contact with the electrode. The distances between the faces are equal, and there is no motion in the X and Y directions.

[0089] The time for the anode and cathode surfaces of the battery plate to complete the glue line paving is 2.5 Min. At the same time, 10 battery plates are randomly selected from every 100 pieces of the products obtained in this embodiment, and two groups of test samples are taken for 25 minutes respectively. ±2°C and 100±5°C detection, the specific results are shown in Table 3.

Abstract

The invention relates to a glue dispensing and glue line paving all-in-one machine and a glue line paving process of a fuel cell polar plate. The all-in-one machine comprises a rack, a transfer unit, a glue dispensing unit, a glue line paving unit and a polar plate overturning unit, wherein the transfer unit comprises a carrier and a moving carrier, the glue dispensing unit comprises a glue dispensing head and a glue supply part, the glue line paving unit comprises a glue line paving platform and a vacuum chuck, and the polar plate overturning unit comprises a plate taking assembly and a plate overturning assembly. On one hand, accurate alignment glue dispensing and glue line paving and integrated processing operation are implemented under the same moving carrier, and pole faces are interchanged to turn over plates, so that glue line paving is efficiently completed, and the reject ratio of products is greatly reduced; and on the other hand, wave-shaped glue dispensing is carried out to avoid the phenomena of glue overflow, glue leakage and the like; paving is completed under the uniform pressure of the vacuum chuck; glue line paving can be rapidly achieved after glue dispensing, so that glue drying is avoided, the bonding firmness is improved, and the qualified rate of the finished products is further increased.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to an integrated machine for dispensing glue and glue line paving for fuel cell pole plates, and also relates to a process for laying glue lines for fuel cell pole plates. Background technique [0002] A fuel cell is a power generation device that directly converts the chemical energy present in fuel and oxidant into electrical energy. Fuel and air are sent separately to the fuel cell, and electricity is miraculously produced. It looks like a battery with positive and negative electrodes and electrolytes from the outside, but in essence it cannot "storage electricity" but a "power plant". [0003] The electrode plate is an important part of the fuel cell. At the same time, the electrode plate used needs to be processed as follows: such as dispensing glue and laying glue lines. The more traditional way is: manual dispensing of bipolar plates and manual laying of glue...
