And, as shown in the insert nut take-out and supply jig (170) guide rods (171a) for smoothly guiding the operation plate 173 in the direction orthogonal to the sliding movement direction of the upper linear exerciser (152) Is provided.

In the ejection and supply control device of the injection case insert nut of the mobile communication terminal according to an embodiment of the present invention, the 'insert nut ejection supply control computer' 110, the first air cylinder 150 and the servo motor ( 122) is sequentially operated to move the 'insert nut take-out and supply jig' 170 to the inside of the fixed mold 30 and the movable mold 40 of the injection mold, the second air cylinder 172 and the servomotor Automatic operation mode selection unit 111a for inputting an automatic continuous operation command for automatically extracting and supplying the insert nut N in conjunction with 122, the first air cylinder 150 and the servomotor 122. ) And an operation mode selection unit 111 comprising a step operation mode selection unit 111b for inputting a step operation command for manually operating the operation of the second air cylinder 172 step by step. .

The automatic operation mode is a process of taking out and supplying the insert nut, that is, taking the insert nut out of the insert nut supplier 20 and supplying it to a predetermined position (ie, insert nut fixing pin) of a fixed mold. Of course, it means the operation mode to be performed automatically by.

In addition, the step operation mode is a step of taking out and supplying the insert nut by the user, each step (for example, operating the second air cylinder 172 to eject the insert nut, and the first air cylinder 150 Driving the horizontal motion of the upper linear exerciser 152, driving the servomotor 122, the step of sliding the lower linear exerciser, etc.) is a driving mode that operates only by inputting a command key.

In addition, the insert nut take-out supply control computer 110 sets an upper linear exerciser moving distance setting unit 112 for setting a moving distance of the upper linear exerciser and a moving distance of the upper linear exerciser. The lower linear exerciser moving distance setting unit 113 and the motor driving unit 120, the first air cylinder 150, and the second air cylinder 172 based on the automatic continuous operation command and the step operation command. A control unit 114 for outputting a run control signal, a first drive control signal, and a second drive control signal, respectively, and controlling the entire insert nut take-out supply control computer 110; and by the control of the control unit 114 'Upper linear exerciser moving distance storage unit' 115 for storing the moving distance value of the upper linear exerciser inputted from the 'upper linear exerciser moving distance setting unit' 112, and 'lower' by the control of the controller 114 Linear mover moving distance setting unit '113 input from It characterized in that is provided be part comprises a linear travel distance "lower exerciser linear moving distance storing unit (116) to store the value of the exerciser more.

When the motor driving unit 120 receives a run control signal from the 'insert nut take-out supply control computer' 110, the motor driving unit 120 stores the lower linear mover stored in the 'lower linear mover moving distance storage unit' 116. Read the movement distance value and outputs a motor drive control signal corresponding to the movement distance value of the read lower linear motion to the servo motor 122.

The following describes the control operation of the ejection and supply control apparatus of the injection case insert nut of the mobile communication terminal having the above configuration.

First, the user is the distance that the upper linear exerciser 152 and the lower linear exerciser 126 must move horizontally through the 'upper linear exerciser moving distance setting unit' 115 and 'lower linear exerciser moving distance setting unit' 113. When the value is set, the moving distance value input by the control of the controller 114 is stored in the 'upper linear exerciser moving distance storage unit 115' and 'lower linear exerciser moving distance storage unit 116'.

In addition, the operation mode selection unit 111 selects the operation mode desired for operation from the automatic operation mode selection unit 111a or the step movement mode selection unit 111b. When the automatic operation mode selection unit 111a is selected, the automatic continuous mode is selected. An operation command is input to the control unit 114.

The control unit 114 receiving the automatic continuous operation command first outputs the second drive control signal to the second air cylinder 172, and the operation plate 173 is moved by the upper linear exerciser by the pneumatic pressure of the second air cylinder 172. The insert nut N is inserted into the tip of the insert nut ejecting pin 174 by the wind blown from the insert nut feeder 20 in this state and is orthogonal to the sliding movement direction of 152.

After removing the insert nut N as described above, the control unit 114 controls the second air cylinder 172 so that the operation plate 173 retreats.

When the operation plate 173 is retracted and returned, the control unit 114 outputs a first driving control signal to the first air cylinder 150 to operate the first air cylinder 150, which is the first air cylinder 150. By the pneumatic pressure of the upper linear exerciser 152 rides the upper slide (140) is slid by the distance set by the 'upper linear exerciser moving distance setting unit' (115).

When the upper linear exerciser 152 moves by the set distance, the controller 114 outputs a run control signal to the motor driver 120, and the motor driver 120 receiving the run control signal is a lower linear exerciser. The lower linear mover moving distance value stored in the moving distance storage unit 116 is read and a motor driving control signal corresponding to the moving distance value of the lower linear exerciser is output to the servomotor 122.

When the servo motor 122 rotates by the number of rotations corresponding to the received motor drive control signal, the screw rod 124 rotates so that the lower linear mover 126 removes the insert nut from the insert nut extraction and supply jig 170. The pin 174 advances toward the stationary mold 30 until the pin 174 reaches a predetermined position of the stationary mold from which the movable mold is separated.

The operation plate 173 is operated by the pneumatic pressure of the second air cylinder 172 on the basis of the control of the control unit 114 in the state that the 'insert nut extraction and supply jig' 170 is located in the stationary mold 30 as described above. Approach to the stationary mold 30 to supply the insert nut to the insert nut fixing pin (not shown) of the stationary mold (30).

When the insert nut supply operation is completed as described above, the first air cylinder 150 is operated to retreat the upper linear exerciser 152, and then the servo motor 122 is driven to retract the lower linear exerciser 126 to insert the 'insert nut. The takeout and supply jig'170 is returned to the initial position.
