Description

Cylindrical battery pin disposable automatic welding device

technical field

The invention relates to the field of primary lithium battery product assembly, in particular to a one-time automatic welding device for cylindrical battery pins.

Background technique

The current two types of batteries, ER14505 and CR14505, require soldering pins with a diameter of 0.8mm and a length of 45mm at both positive and negative ends. The current production process is to purchase the lead pins that have been cut and weld them manually. Because it is manual welding, the contact between the lead pins and the negative electrode is not reliable when the negative electrode is welded, which will cause the current output of the welding machine to be inaccurate. Stability, which will cause explosion when the lead pin and the negative electrode are welded. In severe cases, the bottom of the battery may be penetrated, resulting in the scrapping of the battery and may even cause injury to the operator. In order to prevent this from happening again, we have to solve it by adding a pole piece at the negative end. (See Figure 1).

First weld the guide pin to an increased pole piece, and then weld the pole piece with the guide pin to the negative pole of the battery. Although this traditional process method is feasible in the production process, in terms of material cost, the cutting of lead pins and the increase of pole pieces will increase the material cost of a single product, and the increase in the process will also increase the manufacturing cost. At the same time, due to the manual operation, the production efficiency is also restricted accordingly.

working principle:

1. Loading and unloading of materials

The feeding mechanism is used to pre-install and store batteries and ensure material supply during continuous welding. Through the photoelectric detection of the notch of the transfer trough, when there is no battery in the notch, the wheel is driven to rotate. When the wheel rotates to a certain angle, the battery will automatically fall into the transfer trough and the battery will be sent to the take-out through the movement of the displacement cylinder. The material and the positioning position are waiting for the material to be picked up. When the material retrieving is completed, the displacement cylinder gets back to the initial position and repeats the above actions.

2. Loading of battery at welding position

The battery is waiting at the picking and positioning position. Through the movement of the manipulator displacement cylinder, the battery is grabbed from the waiting position by the manipulator into the welding positioning mold and fixed by the manipulator lifting cylinder, waiting for welding. This equipment uses dual manipulators, that is, one manipulator is used to grab the batteries waiting to be welded, while the other grabs the welded batteries and puts them into the collection tank.

3. Fixed length and cutting of electrode wire

After the electrode wire is primary calibrated by the guide wheel and the wire guide nozzle, it is then aligned by a set of alignment wheels to ensure that the electrode wire welded on the battery can meet the customer's appearance requirements. The fixed-length cylinder is used to convey the length of the electrode wire required by the product, and the cutting is carried out by the cutting cylinder. Slitting is achieved through the dislocation of blade 1 and blade 2. The advantage of this cutting method is that after the pole wire is cut, the cutting surface of the pole wire is smooth without peaks, which is conducive to welding and will not cause explosion.

4. Welding fixture

The electrode wire separates the two poles of the welding machine through the insulating nozzle, the lead pin is in full contact with the first electrode, and the second electrode is the electrode at the other end of the welding machine. Due to the action of the spring, the electrode wire is pressed against both ends of the battery to ensure reliable contact and constant pressure. The beneficial effects of the present invention are:

The feeding mechanism of the present invention is used to store batteries awaiting processing. The battery feeding and discharging mechanism takes out the batteries to be welded from the storage mechanism and sends them into the welding mold to wait for welding. The electrode wire straightening mechanism straightens the wire to be welded to ensure the appearance design requirements and welding requirements.

The electrode wire length fixing mechanism of the present invention is used to meet the customer's requirement on the electrode wire length. The electrode wire cutting mechanism cuts the electrode wire with a predetermined length. The electrode wire feeding welding position mechanism sends the cut electrode wire to the welding position for welding process. The last part is to use the manipulator to move in and out of the battery before and after welding.

The present invention adopts the combined use of the pressure-stabilizing pneumatic element and the spring, so that the contact between the lead pin and the negative electrode of the battery is more stable and reliable, so that the special welding function of the welding machine can be used without adding pole pieces The job of soldering the lead pin firmly to the negative terminal of the battery is done.

In the present invention, except that the battery feeding is manually pre-assembled, the rest of the process is automatically completed by the machine at one time, thereby greatly improving the work efficiency. The reduction of material cost, the reduction of processing procedures and the efficiency of manual welding are combined to see that the welding efficiency of this device is more than ten times that of the original production efficiency. It not only greatly improves the production efficiency, but also greatly reduces the welding efficiency. labor intensity of workers.
