Description

  The present invention relates to an automatic dispenser mechanism, and in particular, after dispensing a sealing resin on a semiconductor chip, an electrical characteristic inspection and an optical inspection are performed. If there is a problem, the dispenser dispenses to the chip. The present invention relates to an automatic dispenser mechanism that improves the yield by adjusting and adjusting the amount.

  In the manufacturing process of the surface-mount type light emitting diode, a plate on which a plurality of chips are arranged at intervals on the surface is placed on the rail on the top of the dispenser by the plate transport device. The plate on the rail is sent to a heating area on the side of the dispenser for heating. Thereafter, when the dispenser above the dispenser table dispenses the chip on the plate, the surface-mounted light emitting diode is sealed.

  In the above process, the surface mounting type light emitting diode is inspected by applying an average amount of coating material on each surface mounting type light emitting diode after a predetermined number of light emitting diodes are put on a precision weighing instrument and the whole weight is weighed. A method in which the quantity is calculated and tested to meet the criteria. Therefore, the operation is interrupted when the amount of the dispenser coating material is adjusted. In addition, since characteristics such as emission intensity and emission color cannot be accurately inspected with respect to the surface mount type light emitting diode, the inspection result lacks accuracy, resulting in a decrease in yield and an increase in cost. In the factory, it is necessary to provide an inspection place with a precision measuring instrument in addition to the place where processing is performed, and the space is limited. Therefore, more space than necessary is required, and the production cost increases.

  As described above, how to solve the disadvantages in the manufacture and inspection of the conventional surface-mount type light emitting diode has been an important issue.

3-6, the plate arrangement | positioning base 4 which has arrange | positioned the several plate 5 is provided in the both sides of the conveyance path 11 of the plate conveying apparatus 1 of this invention. A plurality of chips 51 are arranged on the upper surface of the plate 5 at intervals. The chip 51 has lead wires (not shown) on both sides.
When the plate 5 enters the belt 124 of the plate conveying device 1 from the plate placement table 4, the entry sensor 161 detects the plate, and the motor 121 of the first driving device 12 moves the driving seat 122. When the belt 124 (belt, gear, etc.) hung on the plurality of rollers 123 starts to rotate, the plate 5 on the belt 124 moves above the heating device 14. Then, the positioning sensor 162 detects the plate and the motor 121 stops. When the first cylinder 141 of the heating device 14 raises the heating plate 143 on the interlocking portion 142 to contact the plate 5, and the plate 5 contacts the bottom surface of the positioning plate 113, the heating device 14 heats the plate 5. .

When the drive rod 312 in the first moving module 31 of the moving device 3 slides the slide plate 313 on the first rail 311, the interlocking unit 322 moves the third moving module 33 perpendicular to the second moving module 33. The processing device 2 on the moving device 3 can reciprocate in a horizontal plane by an operation combined with sliding on the rail 321.
When the power unit 332 of the moving device 3 is combined with the operation of moving the moving unit 333 vertically on the third rail 331, the moving device 3 moves the processing device 2 on the plate 5 in the horizontal plane and in the vertical direction. Can be made. Dispensing is performed on the chip 51 of the plate 5 by passing a nozzle (not shown) of the dispenser 22 through a through-groove 1131 that opens up and down the positioning plate 113. The material used for dispensing is epoxy resin or silicon resin, and the light emitting diode is sealed on the chip 51 of the plate 5.

  The drive rod 312, the interlocking unit 322, and the power unit 332 of the moving device 3 only need to be able to move the processing device 2 horizontally and vertically. Therefore, there are a plurality of connecting rods driven by motors, belts driven by gears, telescopic rods driven by cylinders, and the like. Any combination of these parts may be used. However, it is not limited to this.

When the process of dispensing the automatic dispenser on the plate 5 is completed, the motor 121 of the first driving device 12 rotates in the reverse direction. When the drive seat 122 moves the plate 5 on the belt 124 to above the electrical characteristic inspection device 15, the movement sensor 163 detects the plate 5 and stops the motor 121. At this time, when the second cylinder 151 of the electrical characteristic inspection device 15 raises the circuit board 153 by the interlocking unit 152 to contact the plate 5, the circuit contact of the circuit board 153 is electrically connected to the plurality of lead wires of the plate 5. In contact with each other and electrically connected. When the plate 5 comes into contact with the bottom surface of the positioning plate 113, the circuit board 153 turns on the light emitting diodes on the plate 5. Thereby, it can be test | inspected whether a light emitting diode light-emits.
An imaging positioning lens 23 is disposed in the processing apparatus 2, and the imaging positioning lens 23 is a CCD, CMOS, or other imaging device. When the moving device 3 moves the processing device 2 onto the plate 5, imaging is performed by the imaging positioning lens 23. When the imaged plate 5 has a deviation, the moving device 3 causes the processing device 2 to adjust the position. Further, the belts 124 and 134 dispose the plate 5 on the circuit board 153, thereby preventing the position of the optical inspection device 24 from shifting and preventing the situation where the light-emitting diode cannot be faced accurately. 24 assists in placing directly above the light emitting diode. The optical inspection device 24 inspects the characteristics of the light emitting diode, such as the wavelength, CIE standard color system, and light intensity.

  The optical inspection device 24 of the processing device 2 is connected to an external computer, and can be operated by inputting inspection numerical values that the optical inspection device 24 has performed on the light emitting diodes. Further, the calculation result performed by the computer is fed back to the processing device 2 so that the processing device 2 adjusts the amount of material dispensed on the chip 51. Thereby, a yield can be improved. When dispensing is performed on the light emitting diodes on the plate 5 and sealing is completed, the optical inspection device 24 inspects the light emitting diodes to determine whether or not the light emitting diodes meet the requirements. If the inspection result is not satisfactory, the amount of material dispensed is adjusted by the above method, and correction is performed until the characteristics of the light emitting diode are satisfied. This improves the yield of the light emitting diodes. The above inspection and adjustment are performed only within a predetermined time (for example, 1 hour or 2 hours) only at a predetermined number of times (for example, once or twice). In addition, inspection and adjustment can be performed each time dispensing is performed. However, it is not limited to this.

  The processing device 2 includes a dispenser 22, an imaging positioning lens 23, and an optical inspection device 24. The processing device 2 may perform dispensing and inspection separately. Each process carries the plate 5 by sharing the plate conveying device 1. If there is one moving device 3, the processing device 2 can be moved, so that the volume of the entire facility is reduced and the factory is used. Space can be saved. Further, the inspection time that the optical inspection device 24 performs on the light emitting diode can be set to 5 minutes, 30 minutes, or the like, and the extraction inspection can be performed.

  Depending on the different form of the plate 5, the dispensed light emitting diode is of SMD type or LAMP type. In the plate conveying device 1, the circuit contact on the upper surface of the circuit board 153 contacts the contact at the bottom of the plate 5, the contact at the bottom of the plate 5 conducts to the contact at the top, and the top of the plate 5 has a plurality of light emitting diode leads. Electrical inspection of the light emitting diode is made in electrical contact with the wire. The plurality of lead wires of the light emitting diode are placed inside the plate 5, the circuit contact of the circuit board 153 contacts the contact of the plate 5, and the contact of the plate 5 is electrically connected to the plurality of lead wires of the light emitting diode. The electrical inspection may be performed. Further, the plurality of lead wires of the light emitting diode may be penetrated into the plate 5 to be in electrical contact with the circuit contacts of the circuit board 153. However, it is not limited to this.

  In the plate conveyance device 1, when the first driving device 12 enters the plate 5, the heating device 14 heats the plate 5. At this time, the second driving device 13 causes the plate 5 to enter. At the same time as the first driving device 12 dispenses or inspects the plate 5, the second driving device 13 heats the plate 5. In this way, the first drive device 12 and the second drive device 13 work simultaneously and do not need to wait until the plate 5 is processed, avoiding waste of work time and processing steps. Can be shortened.

Please refer to FIG. FIG. 7 is a perspective view showing the width adjustment of the plate conveying device. As shown in FIG. 7, when the size of the plate to be processed is different in the pair of left and right transport paths, it is necessary to adjust the width of the left and right transport paths according to each.
Since the slider 192 of the positioning seat 19 and the moving wall 112 are coupled, when the connecting seat 182 is moved by the screw rod 181 of the width adjusting device 18, the moving wall 112 coupled to the connecting seat 182 is also moved in conjunction with it. When the moving wall 112 moves on the rail 191 of the positioning seat 19 together with the slider 192, the width between the fixed wall 111 and the moving wall 112 can be adjusted. Thereby, plates 5 having different sizes can be used, and the practicality can be improved.

The width adjusting device 18 and the positioning seat 19 are provided at different positions outside the fixed wall 111 or the moving wall 112, but they are not overlapped with each other, which is convenient for installation. . The positions of the two positioning seats 19 only need to allow the moving wall 112 to move at equal intervals.
The moving device 3 only needs to be able to move the processing device 2 above the plate 5 and is disposed on the opposite side of the passage 110 of the fixed wall 111 or the moving wall 112 of the plate conveying device 1. However, it is not limited to this.
