[0049] The implementation principle of the positioning dispensing device for thyristor chip processing in the embodiment of the present application is as follows: when in use, the chip is first placed on the top of the placement table 2, and then the y-axis direction of the dispensing head 13 can be adjusted by starting the two electric slide rails 5, and the electric slider 7 is started to slide on the support arm 6, so that the X-axis direction of the dispensing head 13 can be adjusted, and the position of the dispensing head 13 can be easily adjusted to achieve multi-directional mobile positioning of the dispensing head 13. After adjusting the position of the dispensing head 13, the two hydraulic cylinders 18 are started, so that the two hydraulic cylinders 18 respectively drive the two sliding blocks 4 to move downward, so that The two sliding blocks 4 drive the two electric sliders 7 and the support arm 6 to move downward, which can drive the dispensing head 13 to move downward.
