Description

[0001] The present invention relates to a conveyor provided with means for positioning a jig,

The present invention relates to a conveyor having means for positioning a jig. For example, a plurality of plate-shaped fin plates are provided in a flux cylinder containing a flux (filler) applied to a plurality of plate-like fin plates for brazing To a conveyor having means for positioning a jig used for immersion and rotation.

The oil used in the automatic transmission transfers power within the torque converter of the automatic transmission and lubricates the rotating elements such as gears or bearing elements and is used as hydraulic fluid for various hydraulic devices, such as valves, clutches, and brakes. Each sliding part is cooled, stored in an oil pan connected to the lower part of the transmission case, and supplied to various valve mechanisms and hydraulic operating elements through an oil pump.

In an automatic transmission, oil lubricates and cools each part, so it is important to keep it below a certain temperature. That is, when the temperature of the oil increases, the oil level rises. When the oil level decreases, the oil amount becomes excessive and an overflow phenomenon occurs. As a result, the automatic transmission is not operated smoothly.

 For example, it is recommended that the temperature of the engine oil should not exceed about 90 ° C. However, since the temperature of the oil is raised by each lubricating portion, the cylinder and the piston, and the temperature of the oil is increased, It becomes necessary.

The oil cooler causes the cooling water cooled in the radiator and the high-temperature oil generated from the automatic transmission to cross each of the layers of the oil cooler so that the high-temperature oil exchanges heat with the cooling water to lower the temperature of the oil, And the temperature of the oil is increased to a suitable temperature by the cooling water maintained at a constant temperature in the radiator by circulating the oil in the automatic transmission that is cold during the winter season.

In this regard, a technique relating to a plate stack type oil cooler having a cooling water center and an oil center separately is disclosed in Korean Patent Laid-Open Publication No. 2011-0076344 'plate laminated type heat exchanger of oil cooler'.

The above-described technique has a plate-shaped upper fin plate having a surface with a corrugated bent portion continuously and having a flux coating layer formed on its surface, a plate-shaped lower pin having a corrugated portion corresponding to the upper fin plate, A fin plate assembly for forming a honeycomb cooling water flow space in which the corrugated bends of the upper and lower fin plates are in contact with each other; And a heat exchanger assembly mounted so as to be able to communicate with the fin plate assembly on which the radiator fins are mounted, and an inlet and outlet pipe for flowing cooling water and oil to the fin plate assemblies and the radiator fins, , The product is coated on the surface of each component during brazing welding The heat exchanger assembly is formed by welding the assembled components of the heat exchanger assembly to separate the space for the cooling water and the space for the oil to flow. And an oil flow space for allowing the oil to flow along an empty space formed between the laminated layers of the pin plate assemblies. The upper and lower portions of the pin plate assembly have inlet and outlet ports for cooling water and oil, The heat exchanger is a plate laminate heat exchanger of an oil cooler constructed by arranging pipes.

In order to apply the flux to the upper and lower pin plates, one or both of the upper pin plate and the lower pin plate is held by a hand in a positive cylinder containing the flux liquid, A problem arises in that the gripping portions of the upper fin plate and the lower fin plate are not coated with the flux liquid and that only one or two of the upper fin plate and the lower fin plate can be applied in one coating process, Lt; / RTI >

A jig for solving such a problem has been proposed in the patent application specification filed by the present inventor.

 The proposed jig includes a main body, a plurality of fixtures that can be stacked and mounted by using a plurality of the pin plates using through holes formed in a diagonal direction facing the pin plate as a workpiece, A plurality of rails provided on the main body so as to allow the plurality of rails to be loaded, a plurality of rails provided on the main body, A plurality of stoppers mounted on the body, and a plurality of female arms for gripping formed on upper, lower, left, and right sides of the body so as to be gripped by the gripper.

The proposed jig is transferred to the cleaning and drying chamber after a plurality of fixing bars are manually mounted on the entire fixing table, and a plurality of fin plates laminated on each of the fixing tables are washed and dried before being transferred to the coating device.

The gripping means is inserted into a plurality of gripping female portions formed at upper, lower, right, and left sides of the main body of the jig so that the jig is loaded in the applicator and immersed in the flux liquid and rotated.

Therefore, in order to grasp the jig discharged from the cleaning and drying chamber and grip the gripping means of the applicator, there is provided a jig positioning means capable of accurately positioning the plurality of gripping female portions provided in the jig automatically Conveyor is required.

The present invention has a problem to provide a conveyor that can satisfy the above-mentioned need.

The present invention relates to a vehicle comprising: a carriage rotatably mounted on a plurality of wheels that roll on rails laid on the floor; A rack mounted on the floor adjacent to the rail and extending parallel to the rail, and a pinion meshing with the rack and fixedly mounted on a rotary shaft of a rotary motor mounted on the rack; And a plurality of cylindrical rollers extending in parallel with the rails while being spaced apart from each other so as to be able to pass the jig being conveyed, both ends of which are rotatably mounted on the upper part of the truck and are rotated in one direction by a drive motor Jig loading means; A first elevating means for elevating and lowering a main plate rotatably mounted at a center, with a centering pin installed at a center, which can be selectively inserted into a female groove formed at the center of the bottom of the jig; Second elevating means mounted on the main plate so as to face each other in a diagonal direction to elevate and lower a pair of positioning pins selectively inserted into a pair of positioning holes formed diagonally opposite to the jig, And a rotating means mounted on the main plate for rotating the guide plate on which the centering pin is erected, so as to solve the above problems by providing a conveyor capable of determining the position of the jig.

In the present invention, when a jig loaded with a larger number of pin plates (for example, several hundreds) than before is transferred from the pin plate cleaning jig to the gripping position of the flux applying device, the jig It is possible to stably transfer a plurality of fin plates by a plus coating apparatus automatically without malfunction so as to provide a better coating quality and to increase the coating operation efficiency as compared with the prior art.
