Referring to the process diagram of Figure 5 the operation method for the present invention dedicated automated pallet apparatus configured as described above is as follows.

 The pallet device arrives at the engine assembly line (S10). At this time, the assembly line checks the positions of the workpiece seat support pillars 20 of the pallet device and the workpiece seat pins 30 coupled thereto. The cylinder block is loaded. (S20) And after checking the engine specification of the ID mounting bracket, the equipment starts to work automatically (S30). The work is completed when the cylinder block is in the top-up state. When the cylinder block is lifted (S40), after the cylinder block is raised, the work mounting pin portions of the WORK mounting pins 20 attached to the WORK seating support pillar portion 20 of the pallet device are automatically opened to the outside. At this time, if the pin is opened automatically, the robot checks the origin of the WORK seating pin (S60), and after checking the origin, rotates the cylinder block 180 degrees and seats on the pallet device (S70). Therefore, the cylinder block cuts off the work of each part in the TOP DOWN state. When complete sikimyeo (S80) is complete, to the cylinder block thereby to change the vertical lazy (S90). Automatically assemble the piston and the parts attached to the mounting surface to the vertically seated cylinder block (S100), and in the case of the V-shaped engine, rotate by the mounting angle by the rotary table to mount the piston on one side (S110). The piston of one side is automatically mounted on the rotated cylinder block (S120), and when the piston installation is completed, the cylinder block is changed to the top down state to end all operations such as an oil pan (S130). When the mounting operation of the cylinder block in the top down state is completed, the cylinder head and all parts are automatically assembled by changing to the top up state again (S140). When the process of such automatic assembly is finished, the pallet device is taken out to the manual process (S150).

As a feature of the present invention, first, the WORK seating support pillar 20 for seating the engine is a cylinder, the machining is processed to ultra-precision tolerances, optimized roughness after grinding, the workpiece after machining into a cylinder (WORK) The seating support pillar 20 is mounted after mounting the base portion 10 to optimize the shaking and seating properties to precisely set the mounting tolerances to precisely settle the engine.

Second, in order to prevent the clearance of the bracket (bracket) and to prevent the cumulative movement during transport (base) 10, WORK mounting support pillar 20, WORK mounting pins 30, Wok ( WORK) At the time of mounting the guide pillar 40 for mounting, it was fastened with bolts of at least three points and the peripheral tolerance was measured three-dimensionally so that it belonged to the precision tolerance.

Fourth, after receiving the arrival signal of the pallet device to prevent the smooth automatic assembly process is not performed in the post process because the cylinder block is rotated 180 degrees, it is mounted at an angle to the pallet device because the correct seating position does not match. The cylinder block is rotated 180 degrees for the robot to set the correct position to seat safely and accurately on the pallet unit.

Fifth, when the V-shaped type engine is assembled, the upper part of the engine is wider, causing interference of the post bracket when the engine is rotated 180 degrees, and the engine is caught by the bracket. In order to prevent the assembly is not possible, the position change stopper 17 is rotated when the cylinder block of the V-shaped engine is rotated 180 degrees, the direction of the post bracket (POST BRACKET) is manufactured to the outside.

Sixth, the brackets and supports of all pallet devices are inaccurate and the machining parts are inaccurate, so when the assembly is prolonged for a long time, the support of the brackets is not twisted and deformed so that the engine is not assembled smoothly. The bracket part of the pallet device is manufactured by grinding and precision processing, and the seating pin part of the conventional cylinder block is manufactured so that it cannot be replaced when it is deteriorated or deformed or used for a long time, but the work seating pin part 30 of the present invention Was manufactured to be replaced when used for a long time or deformed, the pin portion 30 was precision processed so that it can be used for deformation or prolonged use by the cylindrical production.

Seventh, the engine seating part of the pallet unit is not manufactured with precise tolerances, so the left and right tolerances of the engine are severe when used for a long time, causing errors in the automatic assembling machine in a later process, causing a decrease in the operation rate. The engine mounting part of the pallet unit is manufactured with precise tolerances, and then re-verified by three-dimensional measurement so as not to shake left and right, and matching between the seating part and the loading part of the equipment so that it can be decked correctly during loading in an automatic assembly machine process. Precise positional tolerance is set to make sure that matching is done accurately.

Eighth, the bearing cap loaded on the jig of the pallet unit is not accurate and the position tolerance of the jig is not accurate, so the robot is often dropped when loading with the tongs or cannot be lifted with the whole set. To this end, the position tolerance of the bearing cap loading jig 16 was manufactured by ultra-precision machining, and then the position tolerance was measured and installed and manufactured.

Ninth, it was not possible to change the pallet apparatus according to the shape of the cylinder block. However, in the present invention, it is possible to assemble in the shape of all sides of the cylinder block with a variable type work seat support pillar 20 which can adjust the width of the cylinder block support pillar according to the shape of the cylinder block.

Tenth, the assembly direction of the conventional parts was possible only in the upper direction, but the assembly can be automatically assembled on the upper, lower, left, and right sides so that the work loading is freely possible. Increased the operation rate of assembly. Eleventh, in the case of the cylinder block of the V-shaped engine, the automatic assembly of the upper, lower, left, and right sides was not possible, but in this case, the work mounting support column 20 is manufactured in a variable shape, and thus, mounting is possible. Also can be assembled by loading the cylinder block.
