Among them, the camera function is an additional function of the popular mobile phone in recent years. The digital camera module that should be used to activate the phone not only has to meet the requirements of lightness and thinness, but it also has better photographic performance. The digital camera lens module group, the method determines the main factors of photographic performance. In the assembly process of several lens camera modules, a dispensing device is used to glue the camera components. Therefore, it is advantageous to improve the dispensing device. To improve their assembly capabilities. There is an automatic dispensing device with a needle calibration compensation function, which includes a platform, a displacement device, a dispenser, a control device, a calibrator and a sensor. The platform has an upper surface on which the material is placed. The moving device has a base and a positioning arm. The base is disposed on the platform, and the positioning arm is located on the upper surface of the cantilever that moves in the X, y z axis direction with respect to the upper surface. The control device controls the positioning arm to move in the X, y, and z axis directions. The calibrator is disposed on the platform and has a first, second, third surface exposed to the platform and perpendicular to the ζ, γ, and χ axes, respectively. The needle that senses the dispenser is in conflict with the first. :: and the third surface when the sensor can emit - positioning information " Tian Quan punctual, the control device respectively controls the needle to move along the axis of ζ, γ, χ 6 200800413 to the second and second The third surface, and against the corresponding face of the plate, the sensor sends a positioning signal for the control device to compensate for the displacement of the calibration needle. ^ At this point, the device is used in its starting position, and the position of the needle is judged by the human eye. Therefore, human error is generated, and the position of the dispensing cannot be accurately positioned. In addition, due to the difference in the position of the glue after each adjustment, the dispensing amount of the dispensing device is not easy to control, and it is easy to cause the phenomenon of insufficient glue and glue, thereby affecting the imaging quality of the entire lens; on the other hand, it is easy The unevenness of the dispensing amount causes stress at the bonding between the lens and the lens barrel and the spacer ring. Under long-term use, the camera lens module is not available due to the falling of the lens barrel and the spacer ring. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a dispensing device and a dispensing method capable of automatically adjusting the position of a needle. A dispensing device includes a needle, a needle connected to the needle, and a three-axis controller. The needle is provided with a flow passage for flowing the glue. The syringe has an inner cavity for holding the adhesive, and the flow passage communicates with the inner cavity of the syringe, and the syringe is fixed to the three-axis controller. The dispensing device is equipped with a distance measuring device and is electrically connected to the third (four) of the distance measuring device for detecting the distance between the needle and the dispensing position. , - a kind of dispensing method 'includes the following steps, through the dispensing I set the measurement, the above-mentioned dispensing information, the distance between the instrument 4 needle and the dispensing position and the "distance value signal is transmitted to The shaft controller adjusts the needle to the dispensing position of the predetermined 7 200800413 according to the measured distance value, and then dispenses the glue. Compared with the prior art, the dispensing device and the dispensing method can automatically position the needle. , so that the needle and the position of each dispensing position are kept in the same relative position, and the amount of glue is equivalent everywhere, thereby saving the assembly time of the camera lens,
