Description

Technology Field

[0001] The present invention relates to a method for manufacturing an ESS case insert injection molding, and more specifically, to a method for manufacturing an ESS case insert injection molding for an electric vehicle in which two or more parts are simultaneously mounted on a jig of a transfer robot, so that the parts attached to the jig of the transfer robot do not fall while moving to the injection molding machine, and are mounted within a specified position within the mold of the injection molding machine within a tolerance, thereby enabling the manufacturing of a case for an ESS battery for an electric vehicle through the mold of the injection molding machine. Background Technology

[0002] Generally, injection refers to the process of creating a molded product by melting a resin part, supplying it into a closed mold, and allowing it to solidify. In particular, insert injection refers to a molding method used to integrate two or more products of different materials through injection molding.

[0003] Such insert injection is typically applied to perform tasks such as applying resin to busbars and integrating them.

[0004] Meanwhile, in conventional vertical insert injection molding machines, taps, nuts, busbars, etc., are supplied horizontally, and since three or more parts are used instead of just one, the operator conventionally performed the task of directly supplying these parts one by one.

[0005] However, the above operation involves supplying multiple parts to the fixed mold between the fixed mold and the movable mold, which poses a very high risk of safety accidents. Consequently, there were problems in that it was difficult to ensure the safety of workers, and the cost of the process was very high.

[0006] However, in conventional vertical insert injection molding machines, there was a problem in that it was difficult to accurately insert multiple parts into the feed section of the fixed mold after ejecting multiple parts, resulting in a long working time.

[0007] In addition, when supplying multiple parts to the injection molding machine, there was a problem that the work time was long due to the risk of the multiple parts falling.

[0008] As a result, various technologies are being developed recently to automate the supply of multiple parts to injection molding machines. Prior art literature

Claim 3 In claim 1, the third step comprises: a 3-1 step in which the second robot (120) pneumatically attaches an insert tab (13) and an insert nut (14) on the component plate (140) to the attachment portion (122) of the second jig (121); a 3-2 step in which the second robot (120) moves the attachment portion (122) of the second jig (121) on the component plate (140) by a pre-set third z-axis displacement in the opposite direction of gravity; a 3-3 step in which the second robot (120) rotates the second jig (121) by 180 degrees; a 3-4 step in which the second robot (120) moves the second jig (121) in the direction of gravity to approach the component plate (140); and the second robot (120) of the second jig (121). A method for manufacturing an ESS case insert injection molding, characterized by comprising: a 3-5 step of gripping a first insert busbar (11) and a second insert busbar (12) on a component plate (140) with a clamp (123); and a 3-6 step of separating the second jig (121) from the component plate (140) by moving it in the opposite direction of gravity by the third z-axis displacement of the second robot (120).
