Description

Reel clamping module {reel clamping module}

The present invention relates to a reel clamping module, and more particularly, in the process of supplying or taking out a reel in a process of manufacturing a secondary battery or semiconductor, stable fixation of a reel, which is a transfer object, as well as automatic supply and take-out. It relates to a reel clamping module with

As is known, in the process of producing secondary batteries, semiconductors, solar panels, exterior parts of automobiles, etc., transfer objects such as high-load parts or finished products are bulky and heavy, making it difficult for workers to manually proceed with the transfer objects. The object to be transported is moved using an automatic guide vehicle (AGV) for carrying in or out of the vehicle.

This automatic guide vehicle is preset to move in a specific section and is used to supply parts required in each production facility or transport finished products or collection objects after use while moving in the set section, and is configured to be able to drive. and includes a mounting arm on which a traveling and transporting object is mounted.

In the conventional automatic guide vehicle, when an object to be transferred is moved to a designated location while being mounted on a rock, the object to be transferred is brought into the production facility. At this time, the process of bringing the object into the production facility is performed manually Because of this, the object to be transported with a high load fell during loading, which caused an accident.

In addition, there is a problem in that production efficiency is lowered because the production equipment in operation must be temporarily stopped when the transfer object is moved in and out through the conventional automatic guide vehicle. In other words, when a bulky and high-load transfer object is brought into the production facility from an automatic guide transporter, the transfer object is delivered after matching the center axis of the winder of the production facility with the mounting arm of the automatic guide transporter. Since the winder of the facility does not stand by at the same location, but moves during operation or vibration generated during operation of the production facility, it is difficult to maintain the same central axis as the moving arm of the automatic guide vehicle.

As an example of the use of the automatic guide vehicle, there is a production process of a battery pack used in various devices. The battery pack adopts a secondary battery capable of charging and discharging to increase economic feasibility and operating time. Representatively, there are lithium secondary batteries such as nickel-cadmium (Ni-Cd) batteries, nickel-hydrogen (Ni-MH) batteries, lithium (Li) batteries, and lithium ion (Li-ion) batteries.

The lithium secondary battery has an operating voltage of 3.6P, which is about three times higher than that of a nickel-cadmium battery or a nickel-hydrogen battery used as a power source for portable electronic equipment, and has a high energy density per unit weight, so the application range is widened. there is a trend

These lithium secondary batteries mainly use lithium-based oxide as a positive electrode active material and carbon material as a negative electrode active material, and are generally classified into liquid electrolyte batteries and polymer electrolyte batteries according to the type of electrolyte. It is called a lithium ion battery, and a battery used for a polymer electrolyte is called a lithium polymer battery. These lithium secondary batteries are manufactured in various shapes, typically cylindrical, prismatic, and pouch-shaped.

The above-described secondary battery is manufactured by assembling components of a cathode, a cathode, an electrolyte, and a separator, and can be manufactured through various manufacturing methods. A brief look at a method for manufacturing a lithium ion secondary battery among various manufacturing methods includes stacking a first separator, a negative electrode plate, a second separator, and a positive electrode plate, and then winding them multiple times to form an electrode assembly, and inserting the formed electrode assembly into a case. And after injecting electrolyte into the case, it is sealed to form a finished product.

The negative electrode plate and the positive electrode plate are supplied to each assembly process facility in a state in which they are wound in a reel form due to the characteristics of materials, weight, and manufacturing process conditions, and are then withdrawn at a constant speed.

At this time, the negative plate and the positive plate or the first and second separators provided in the form of a reel cannot be formed into a reel having a diameter greater than a predetermined size due to the weight of the material and the volume of the reel to be wound, so the reel must be periodically replaced during the process.

At this time, the reel that has been moved to the assembly process facility with the replacement reel mounted on the automatic guide transporter must be delivered to the winder of the assembly process facility. If the height and position of the docking arm and winder are different from the height of the floor where the automatic guide transporter is located and the height of the floor of the assembly process equipment is different from the initially set position, the height of the docking arm and the winder may change, allowing the operator to adjust the position of the reel and the winder. The work of confirming and correcting the position of the was required.

In addition, in the process of moving the conventional automatic guide vehicle while the reel is mounted, a separate means for fixing the mounted reel is not provided, so accidents frequently occur during movement, resulting in low stability.
