Description

Installation method of horizontal battery plate

technical field

The invention relates to the field of battery manufacturing.

Background technique

Separators are interposed between the positive and negative plates of lead-acid batteries to prevent short circuits caused by direct contact between the plates. At the same time, in order to prevent the active material from falling off due to the deformation of the plates, store the necessary electrolyte and provide oxygen circulation channels. etc. It is necessary to carry out cladding processing on the alternately arranged positive and negative plates, that is, to wrap the separator between the plates.

However, at present, the assembly and production of batteries is basically manual work, and the production method is as follows: Step 1: Workers take a number of positive and negative plates within a certain weight range and place them on the work table on the right side in front of the seat. Stack them in several piles in an orderly manner; the second step: take a pack of insulating separators for isolating the positive and negative plates, and place them on the designated position on the workbench on the left side in front of the seat; take a pack of rubber bands for binding, and the same Put it on the work table on the left side in front of the seat; Step 3: Clean up the dust and foreign objects on the work table to keep the work table free of debris and dust; Step 4: Take a negative board from the negative board stack with your right hand and place it on In the battery casing; Step 5: Take the separator from the separator with the thumb and index finger of the left hand, gently hold the positive and negative sides of the separator, with the front facing down and the reverse facing up, and stacked on the upper surface of the previous negative plate , the center line of the separator should basically coincide with the center line of the polar plate; Step 6: Take a positive plate from the positive plate pile with the right hand and place it in the center of the separator. The center line of the separator should be basically the same as the center line of the polar plate Overlap, then bend the separator with the right hand to cover the positive plate, and then press it with the thumb of the left hand; Step 7: Take a negative plate from the negative plate stack with the right hand and place it on the separator that covers the positive plate, Similarly, the center line of the separator should basically coincide with the center line of the pole plate; Step 8: Repeat steps 5, 6, and 7 according to product specifications and process requirements until a cluster package is completed; then use a rubber band on the pole group Bundle two times horizontally, and put the assembled pole group into the cluster box.

The above-mentioned wrapping process is completed manually, and the efficiency of completion varies with the complexity of the worker's work, fatigue, emotion, and work environment. Moreover, because it is a manual operation, this action cannot be carried out with high intensity for a long time, and the production efficiency is relatively high. Low. At the same time, because the workers repeatedly touch the plates, the lead dust falling on the surface of the plates will affect their health. At the same time, the positive and negative electrode powder sticking to the worker's hands during the wrapping process will be transferred to the separator, so that the positive and negative electrode powder on the separator is easy to mix with the positive and negative electrode powder on the inner plate of the separator, resulting in The positive electrode powder or negative electrode powder on the plate conducts with the negative electrode powder or positive electrode powder on the separator and discharges itself, which affects the stability of product performance.

Contents of the invention

The purpose of the present invention is to solve the problem that the existing storage batteries are assembled manually, and such an assembly method affects the stability of product performance.

In order to achieve the above purpose, the basic solution of the present invention provides a method for installing horizontal battery plates, and the specific steps are as follows:

The first step: determine the value, first set the path and value of the plate cutting table, the conveyor belt, the first mechanical arm and the second mechanical arm;

Step 2: Stack the polar plate and the separator, place the separator stack on the adsorption path of the first mechanical arm, and place the bipolar plate and unipolar plate stack on the adsorption path of the second mechanical arm;

Step 3: The first layer of separator is placed, the control mechanism controls the conveyor belt that transports the battery case to stop at the installation station, and then the control mechanism controls the first mechanical arm to absorb the separator through the first suction plate and place it in the battery case first;

Step 4: Place the bipolar plates on the first layer, and the control mechanism controls the second mechanical arm to absorb three sets of bipolar plates through the second suction plate and place them on the first layer of separators. When the second suction plate absorbs the bipolar plates, The resistance detection rods on both sides of each suction cup are in contact with the surface of the bipolar plate at the same time to judge the correct placement of the bipolar plate and adjust the position of the bipolar plate;

The principle of the fourth step is to set the correct initial value in the control mechanism. When the second suction plate absorbs the bipolar plate, the resistance detection rods on both sides of each suction cup will touch the surface of the bipolar plate at the same time, and the resistance on both sides will The difference detected by the rod is fed back to the control mechanism. If the detected value is correct, the installation work will continue to the next step. If there is an error, the second mechanical arm will be controlled to absorb another bipolar plate until the detection is correct and placed in the battery case.

Step 5: Place the second layer of separator, the first mechanical arm absorbs the separator, and place the second layer of separator on the placed bipolar plate;

Step 6: The second layer of bipolar plates is placed, the control mechanism controls the middle four sets of suction cups of the second suction plate to open and absorb two sets of bipolar plates, and then the second mechanical arm places the two sets of bipolar plates on the second layer of separators middle;

Step 7: Place the unipolar plates at both ends, the second mechanical arm moves to the stacking position of the unipolar plates, and controls the two sets of suction cups in the middle of the second suction plate to absorb a group of unipolar plates and move to the position of the plate cutting table. The cutting table cuts the set of unipolar plates from the center into two unipolar plates, and then the second mechanical arm places the cut two unipolar plates on the second side of the battery case where no bipolar plates are placed at both ends. on the second floor;

Step 8: Complete the installation, complete the installation of the horizontal battery plate, seal the battery case and the next step after the installation is completed.

The beneficial effect of this basic scheme is that,

1. This method adopts fully automated installation, which ensures high installation accuracy and ensures the stability of the battery.

2. The installation efficiency is high by using this method, which realizes streamlined automatic installation and avoids the phenomenon of large error and low efficiency of manual installation.

3. The setting of the resistance detection rod enhances the accuracy of installation and avoids the occurrence of installation errors.

Scheme two, this is the optimization of the basic scheme, each group of suction cups on the first suction plate in the third step and the second suction plate in the fourth step are not less than two. Enhanced adsorption stability.

Scheme 3, this is the optimization of the basic scheme. In the third step, before the first layer of separator is placed, six pressures are evenly distributed horizontally in the battery case. The setting of the pressure box adds to the overall strength.

Solution 4, which is the preferred option of the basic solution, is provided with a cutting knife on the plate cutting table, and the cutting knife is controlled by a control mechanism. When the second mechanical arm absorbs the monopolar plate to the position of the pole plate cutting table, the control mechanism controls the cutting knife to cut the monopolar plate.

Scheme five, this is the preference of the basic scheme, the partition is an AGM partition. AGM separator is an ultra-fine glass fiber separator, which is made of ultra-fine glass fiber through emulsification, washing, drying and other processes, similar to papermaking technology, because the ultra-fine glass fiber separator has a large acid absorption capacity and high porosity. (about 95%), small pore size and other characteristics, so it is widely used in maintenance-free sealed batteries.
