Abstract:
The present invention is forming equipment for a pouch, and comprises: a transport apparatus that transports a pouch film; a forming apparatus that forms an accommodation portion for accommodating an electrode assembly by pressurizing the top surface of the pouch film that has been transported by the transport apparatus; and an inspection apparatus that calculates a depth value of the accommodation portion formed in the pouch film, and inspects whether or not a defect has occurred by comparing the calculated depth value with a set input value, wherein the inspection apparatus includes: a distance measurement member that is provided at a reference point set above the pouch film, and respectively measures a first measurement value that is a distance from the reference point to the pouch film connected to the top end of the accommodation portion and a second measurement value that is a distance from the reference point to the bottom surface of the accommodation portion; and an inspection member that calculates the depth value of the accommodation portion by subtracting the first measurement value from the second measurement value measured by the distance measurement member, determines to be normal if the calculated depth value is located within the set input value, and determines to be defective if located outside.
