[0057] First, the position sensor 40 senses that there is a crystal bar below the glue applying pipe part 37, and the signal is transmitted to the control processor 41. The control processor 41 controls the start of the second motor 22, so that the glue applying pipe part 37 is close to the crystal bar to a suitable distance. Then, the control processor 41 controls the start of the first feeding pump 11a and the second feeding pump 11b. The first feeding pump 11a pumps the A glue in the first storage barrel into the rear first conveying pipe, and the second feeding pump 11b pumps the B glue in the second storage barrel into the rear second conveying pipe. At the same time, the control processor 41 also controls the first mixing pump and the second mixing pump to rotate at corresponding rotating speeds. The first mixing pump pumps the A glue in the first conveying pipe 12a into the first branch pipe 32a, and the second mixing pump pumps the B glue in the second conveying pipe 12b into the second branch pipe 32b. Then, the A glue and the B glue flowing to the mixing pipe assembly can be mixed at a suitable ratio. Finally, the mixed glue flows out of the glue applying pipe part 37.

[0058] Based on the above embodiment, the advantages of the present application are as follows:

[0059] By transmitting the A glue from the first storage bucket to the first branch pipe 32a and then to the mixing pipe assembly, and transmitting the B glue from the second storage bucket to the second branch pipe 32b and then to the mixing pipe assembly, the phenomenon that the traditional single-component glue is blocked in the delivery pipeline due to solidification is avoided. During this period, the rotational speed of the first mixing pump and the rotational speed of the second mixing pump are controlled by the control processor 41 respectively, so that the above two kinds of glue can be accurately mixed in the mixing pipe assembly according to the appropriate ratio, and the gluing efficiency of the crystal bar is improved.
