Description

Semi-conductor feed mechanism

The present invention relates to a sawing sorter system of a semiconductor, and more particularly, to an apparatus for supplying a semiconductor material to each stage in a sawing sorter system.

In general, the sawing sorter system is arranged to perform each process on the plate so that the cutting process of the cutting machine is followed by other processes continuously. The cutting machine performs cutting, cleaning and drying processes in which balls attached to the printed circuit board are bonded and separated molded semiconductor packages, one by one, and the devices on the plate use a printed circuit board in which the semiconductor package is bonded to the cutting machine. After supplying and transporting the finished semiconductor package, it covers various parts and loads them in a tray. In this case, in order to smoothly perform the above complicated process, the material must be accurately transferred and supplied to each stage.

Conventionally, the semiconductor material supply apparatus equipped with the air cylinder was used as the apparatus which supplies the said semiconductor material to each stage. Specifically, referring to FIG. 1, a guide rail 2 formed on a body, a moving member A moving along the guide rail 2, and a cylinder rod 8a having an end coupled to the moving member. And an air cylinder 8 as a driving means, a material supply arm 7 fixed to the moving member A, a sensor 12, a sensor bar 13, and a spring 9. Referring to the operation relationship of the conventional semiconductor material supply device, when the cylinder rod (8a) is contracted (inserted into the air cylinder), the moving member (A) coupled to it also moves along with the guide rail (2). As a result, the material supply arm 7 fixed to the moving member A is also advanced to supply the material. At this time, the material supply arm 7 and the sensor bar 13 attached to the material supply arm 7 and the sensor bar 13 attached thereto do not move forward, but the other side is fixed to the cylinder rod 8a and the moving member A and the sensor ( Since 12 is advanced, the sensor bar 13 enters the sensor 12 as the spring is compressed. The sensor 13 scans the light and checks the inflow amount. When the sensor bar 13 enters the sensor and interferes with the inflow of the light by the abnormal operation, the sensor 13 notifies the controller (not shown) of the abnormal operation. The controller, which has received the abnormal signal, stops moving forward of the cylinder rod 8a and moves backward.

On the contrary, when the cylinder rod 8a is elongated, the moving member A and the material supply arm 7 move in conjunction with each other to prepare for the material supply (standby) state.

However, the size of the semiconductor material handled in reality is very diverse. Therefore, the size of the material supply arm must be installed differently according to the size of the material to be supplied. Therefore, there are many restrictions in the installation space and equipment, and thus has been a factor that hinders efficient work.

The present invention has been made to solve the above problems, the object of the present invention is to provide a semiconductor material supply device excellent in work compatibility with less influence on the size of the semiconductor material to be handled.

The roller 3 and the wire 4 are rotated clockwise or counterclockwise by receiving a driving force to be described later.

The left and right moving members 5a and 6a reciprocate in the left and right directions along the guide rails 2 and interlock in opposite directions. That is, when the left moving member 5a moves to the left side, the right moving member 6a moves to the right side. On the contrary, when the left moving member 5a moves to the right side, the right moving member 6a moves to the left side. Their movement is to repeat the movement away from each other.

Material supply arms 7 are coupled to the left and right moving members 5a and 6a. The material supply arm 7 overlaps the ends of the two links 7a and hinges 7b, and pivotally couples the opposite ends to the left and right moving members 5a, 6a.

Left and right connecting members 5b and 6b are provided to transfer the driving force by the rotation of the wire 4 to the left and right moving members 5a and 6a. The left connection member 5b has a fixing portion 5c fixed to the lower portion 4b of the wire, and a hole through which the upper portion 4a of the wire penetrates, and an upper portion thereof is fixed to the left moving member 5a. Or integrally formed. In addition, the right connecting member 6b has a fixing part 6c fixed to the upper part 4a of the wire, and the upper part is fixed to the right moving member 6a or integrally formed.

In this embodiment, the air cylinder 8 is provided as a driving means. The end of the cylinder rod 8a of the air cylinder 8 is fixed to the shaft 10, which will be described later.

As shown, an air cylinder 8 and a cylinder rod 8a are provided, and an end of the cylinder rod 8a is coupled to the head of the shaft 10 passing through the left connecting member 5b. In addition, the other end of the shaft 10 is coupled to the plate-shaped support 11, the spring (9) on the outer peripheral surface of the shaft 10 between one side wall of the left connecting member 5b and the support 11 ) Is put in place. In addition, the support bar 11 is coupled to the sensor bar 13, the sensor 12 is attached to a position corresponding thereto. The sensor 12 may be a sensor used in a conventional semiconductor material supply apparatus, or other sensors may be used. In addition, a guide bar 14 is coupled to the support 11, and a guide hole 5d is formed in the left connection member 5b correspondingly.

FIG. 4 is a front perspective view of a state in which the material supply arm 7 is advanced for material supply in the above embodiment. Referring to this, the operating state of the present embodiment will be described. In the standby (ready) state of FIG. When the 8a is contracted (moved to the right in the drawing), the guide bar 14 is inserted more deeply along the guide hole 5d, and the shaft 10 and the support 11, which are coupled with the cylinder rod, The springs 9 interposed therebetween move to the right together to move the left connecting member 5b to the right, which also moves the lower part 4b of the wire to which the left connecting member 5b is fixed to the right to make the whole. Rotates the wire 4 counterclockwise so that the upper portion 4a of the wire is moved to the left. Accordingly, the left moving member 5a together with the left connecting member 5b moves to the right and the right moving member 6a together with the right connecting member 6b fixed to the upper portion 4a of the wire is left. As a result, the left and right moving members 5a and 6a interlock and approach each other. Finally, as the angle between the two links 7a which are rotatably coupled to each other is narrowed, the material supply arm 7 is advanced to supply materials.

If the advancement of the material supply arm 7 is prevented due to a jam of the supplied material, the moving members 5a and 6a, the wire 4 and the connecting members 5b and 6b cannot stop or move. However, the cylinder rod 8a continues to contract (move to the right side in the drawing). Accordingly, the shaft and the support 11 coupled to the cylinder rod 8a move to the right while compressing the spring, and the sensor bar 13 fixed to the support moves to the stationary sensor 12 while moving to the right to provide light. By interrupting the inflow, the controller is notified of the abnormal operation. The control unit (not shown) in which the abnormal signal is received stops the operation of contracting the cylinder rod 8a and further extends the cylinder rod 8a.

When the material supply is completed by the above operation, the wire 4 is rotated clockwise as the cylinder rod 8a is extended (moved to the upper left in the drawing), and the gap between the left and right moving members 5a and 6a. As the gap is opened, the angle between the two links 7a is opened so that the material supply arm 7 is reversed.

In the above embodiment, the driving means is an air cylinder 8, but it can also be driven by a motor. In this case, the roller 3 is directly rotated clockwise or counterclockwise by a motor so that the left and right connecting members 5b and 6b fixed thereto are interlocked. As a result, the material supply arm 7 is advanced. Or it will go backwards.

According to the present invention, since it is less affected by the size of the material to be handled, the work compatibility is excellent, and the installation space is easy because the space required for mounting the device is very small as compared with the related art.

In addition, if an abnormal operation occurs by adding a sensor, there is an advantage that it can quickly detect and respond appropriately.
