3. Explanation of gripping type attachment type of grip type attachment device through material attachment system on mold frame for backlight unit

10 to 12, description will be made of the attachment material (LF) gripping separation process through the gripper 210 of the grip type attachment device 200 in the material attachment system on the mold frame for the backlight unit of the present invention. The gripper 210 'of the gripper 210 constituting the gripper 210U is lowered to the overall working position TP by the third driving element 213c, Only the first grip finger 211 is lowered to abut on the attachment material LF adhering to the upper surface of the film F located on the working position TP by the first grip finger 213a. The first grip finger 211, which is so lowered as to be the subject of the work and which is in contact with the adsorption surface 211A, is provided with a vacuum adsorption force on the adsorption surface 211A by using a vacuum adsorption device, The object to be attached LF 'is fixed to the attraction surface 211A, and then the first driving element 213a lifts the object LF' and restores the height to the first pre-falling position. Finally, when the first grip finger 211 fixing the attachment material LF 'to be a work object through vacuum suction is returned to a height corresponding to the second grip finger 212, the second grip finger 212, Is moved to the side of the first grip finger 211 by the second driving element 213b and pushes the attached material LF 'fixed to the suction surface 211A of the first grip finger 211 to grip the attached material LF When the gripper 210 constituting the gripper unit 210U moves toward the mold frame MF for the attaching process after completion of the gripping process of the attaching material LF, It is preferable to move by the mobile device 220 while maintaining the grip state.

Here, the control of the operating states of the respective driving elements 213a, 213b, 213c and the structures of the vacuum adsorption device and the like is performed through the control device 400. [

More specifically, first, the control device 400 controls the third driving component 213c to move the gripper 210 ', which is an object of the job, out of the gripper 210 constituting the gripper unit 210U, The gripper 210 'is lowered to the working position TP as compared with the remaining grippers 210 so that the gripper 210' is positioned slightly closer to the attaching material LF adhering to the upper surface of the film F .

After the entire gripper 210 'is lowered to a certain level, the controller 400 controls the cold air supply device 600 so that the gripper 210' The cooler is supplied to the attachment material LF 'so that the process can be performed more easily in the gripping and holding of the attachment material LF adhering to the upper surface of the film F by the gripper 210' .

This is because, in the case where the first and second grip fingers 211 and 212 apply an external force to the attachment material LF 'for separation and gripping when the attachment materials LF' So that the separation and grasping can not be precisely performed due to the occurrence of structural deformation.

The controller 400 controls the first driving element 213a to move the first grip finger 211 to the first gripping finger 211 and then the first gripping finger 211 to the first gripping finger 211. [ The first grip finger 211 is lowered so that the suction surface 211A of the first grip finger 211 comes into contact with the attachment material LF ' 11, the control device 400 controls the vacuum adsorption device to suck air from the air suction port 211H formed on the suction surface 211A through the air suction path 211P to the vacuum adsorption device And a vacuum attraction force is applied to the attraction surface 211A so that the adhesion material LF 'to be a work target is fixed to the attraction surface 211A of the first grip finger 211. [

The separation and fixing of the attachment material LF 'of the first grip finger 211 as described above may be performed in such a manner that the two finger fingers of the conventional grip type structure are detached from the material to be separated, So that stable separation and fixation can be achieved without causing problems causing deformation.

The grip type attaching device 200 of the present invention differs from the conventional attaching device structure in which the gripping type two finger members perform gripping in such a manner that the gripping type gripping device is separated from both sides of the object to be separated, Only the fingers 211 perform separation and fixing operations from the upper side of the attaching material LF through the descending and rising and lowering processes so that the degree of interference with the peripheral structure is lowered and the attaching material LF, The manufacturing cost and the production cost can be lowered and the efficiency of the work can be improved.

The control device 400 controls the first driving element 213a so that the first grip finger 211 fixed to the suction surface 211A can return to the original height before the first lowering, The control device 400 controls the second driving element 213b to move the second grip finger 212 toward the first grip finger 211 side as shown in FIG. The gripping portion 211A-2 constituting part of the suction surface 211A of the grip finger 211 and the pressing surface of the second grip finger 212 are positioned between the two and the suction surface 211A of the first grip finger 211 The gripper unit 210U in the grip type attaching apparatus 200 in which the gripping force of the attaching material LF 'which has been vacuum-adsorbed on the grip member 210 is improved and the stable gripping is performed so that the attaching material LF' A stable fixing force can be continuously provided even in the process of moving to the mold frame MF side.

Next, with reference to Figs. 13 to 14, a process of attaching the attachment material LF through the gripper 210 of the grip type attachment device 200 in the material attachment system on the mold frame for the backlight unit of the present invention will be described. The gripper 210 'to be subjected to the work among the grippers 210 constituting the gripper unit 210U is lowered toward the mold frame MF as a whole by the third driving element 213c, The second grip finger 212 is moved to the opposite side of the first grip finger 211 by the driving element 213b and is gripped from the attached material LF 'fixed to the suction surface 211A of the first grip finger 211 So that the process of attaching the attachment material LF 'by the first grip finger 211 can be performed. The gripper 210 'to be subjected to the work is moved by the first driving element 213a so that only the first grip finger 211 attaches the attachment material LF to the attachment position AP on the mold frame MF Respectively. The first grip finger 211, which is attached to the attaching position AP on the mold frame MF by the attaching material LF 'which has been separated and fixed by being separated from the mold frame MF, The vacuum attraction between the attachment material LF 'attached to the attachment position AP and the absorption surface 211A is released, and at the same time, the first drive element 213a is further lowered by the first drive element 213a, A certain level of external force is exerted so that the pressing portion 211A-1 constituting a part of the attracting surface 211A adheres the attachment material LF 'to the attachment position AP on the mold frame MF a little more reliably.

Here, the control of the operating states of the respective driving elements 213a, 213b, 213c and the structures of the vacuum adsorption device and the like is performed through the control device 400. [

More specifically, after the gripper 210 'to be subjected to the work is gripped and separated from the attachment material LF' and then moved to the mold frame MF side, The second gripping finger 212 is moved to the opposite side of the first gripping finger 211 by controlling the second driving element 213b so that the gripping of the second gripping finger 212 to the attachment material LF ' And only the fixing force of the suction surface 211A of the first grip finger 211 is converted into a state in which the attachment material LF 'is provided, so that the attachment of the attachment material LF' by the first grip finger 211 So that attachment can be made.

14, the control device 400 controls the first driving component 213a so that the attached material LF 'fixed to the suction surface 211A of the first grip finger 211 is pressed against the mold The first grip finger 211 is lowered so as to be attached to the attachment position AP on the frame MF. Here, the controller 400 controls the vacuum adsorption apparatus at the time when the attachment material LF 'is brought into contact with the attachment position AP on the mold frame MF by the first grip finger 211, 211A-1 of the attaching surface 211A of the mold frame MF is released and the pressurizing portion 211A-1 forming part of the adsorption surface 211A is lowered and adhered to the attaching material LF ' The upper surface of the opposite side of the mold frame MF is pressed so that the attachment material LF 'is firmly attached to the attachment position AP on the mold frame MF.

Here, the attachment type LF 'of the first grip finger 211 is different from that of the first finger type attachment member LF' in that the two finger members of the conventional grip type structure are attached to each other, The grip type attaching device 200 of the present invention performs the attaching operation from the upper side of the mold frame MF through the downward movement and the vertical movement of the mold frame MF only by the first grip finger 211, The degree of interference is lowered, so that it is possible to perform a free attachment operation irrespective of the structure of various members laminated or installed on the mold frame (MF), and the problem of structural deterioration due to interference with the surrounding structure in the attaching process is eliminated .
