Compared with the prior art, the invention has the beneficial effects that:

the frame provides the support for first linear transmission mechanism and first point gum machine structure, and the staff uses the tool to press from both sides tight LCD screen terminal earlier and makes the some glue positions of terminal both sides expose outside through the through-hole of both sides on the tool, and then the staff places the tool that is equipped with the terminal to first linear transmission mechanism input end department, and tool both sides support tight first linear transmission mechanism both sides inner wall. The staff sends the signal to first linear transmission mechanism through the controller, and its promotion portion promotes the tool and removes to first linear transmission mechanism's output after first linear transmission mechanism receives the signal, and the tool keeps both sides and the laminating of first linear transmission mechanism inner wall all the time in the motion process. At the moment, the first positioning part on the first linear transmission mechanism is in a smooth state, and the second positioning part is in a closed state, so that the first jig moves to the second positioning part through the first positioning part of the first linear transmission mechanism. The sensing assembly at first locating part department senses the tool and sends a signal to the controller after passing through, and the controller sends a signal to the first locating part of first linear transmission mechanism, thereby closes after the first locating part of first linear transmission mechanism receives the signal and ensures that subsequent tool can't pass through, and subsequent tool is kept off in first locating part department. When the head end of the first jig is abutted to the working end of the second positioning part, the sensing part of the first dispensing mechanism is triggered to send a signal to the controller, and the controller sends a signal to the pushing part of the first linear transmission mechanism to enable the pushing part to be closed to ensure that the jig is accurately positioned below the initial position of the working end of the first dispensing mechanism. And then the controller sends a signal to the first dispensing mechanism, and the first dispensing mechanism receives the signal and then the working end of the driver carries out dispensing operation on the first surface of the terminal in the jig through the through hole in the jig. After dispensing, the controller drives the working end of the first dispensing mechanism to return to the initial position and sends signals to the first positioning part, the second positioning part and the pushing part of the first linear transmission mechanism. After receiving the signal, the first positioning part and the second positioning part of the first linear transmission mechanism are opened, so that the subsequent jigs can continue to move towards the first dispensing mechanism, and the first jig can move into the position below the first curing mechanism. When the sensing part of the first dispensing mechanism senses that the first jig passes through the second positioning part of the first linear transmission mechanism, a signal is sent to the controller, and the controller controls the second positioning part of the first linear transmission mechanism to be closed. And then repeating the previous steps to perform the dispensing operation on the second fixture. And the first fixture moves to enter the first curing mechanism and is issued during the process of dispensing operation of the second fixture, the controller sends a signal to the first curing mechanism, and the first curing mechanism works to perform curing operation on the first fixture. After the curing operation is finished, the controller continues the previous steps to move all the jigs to the output end of the first linear transmission mechanism together, and finally the first jig is moved to the clamping part of the turnover feeding mechanism. Then the controller sends a signal to the overturning feeding mechanism, the overturning feeding mechanism receives the signal and then drives the jig to rotate for one hundred eighty degrees around the axis of the overturning feeding mechanism and to enter the input end of the second linear transmission mechanism, and then the controller controls the pushing portion of the overturning feeding mechanism to push the jig into the second linear transmission mechanism from the clamping portion of the overturning feeding mechanism from the two sides of the clamping portion. Upset feeding mechanism inner wall and first linear transmission mechanism, first point gum machine construct inner wall parallel and level to guarantee that the tool can not take place to sideslip among the upset process, and then ensure that the tool accuracy falls in second linear transmission mechanism's input. Then the controller sends a signal to a pushing part of the second linear transmission mechanism to push the jig to move towards the second glue dispensing mechanism and the second curing mechanism. The second linear transmission mechanism is only provided with one positioning part to ensure the dispensing accuracy, the function of the second linear transmission mechanism is the same as that of the second positioning part on the first linear transmission mechanism, and the second linear transmission mechanism is not required to be provided with the first positioning part which is the same as that of the first linear transmission mechanism to block subsequent jigs. The second glue dispensing mechanism on the second linear transmission mechanism is arranged at the head end of the second linear transmission mechanism, and the second curing mechanism is arranged at the back position on the second glue dispensing mechanism. The jig is overturned through the overturning feeding mechanism before, and the second face of the terminal in the jig upwards passes through the second glue dispensing mechanism and the second curing mechanism at the moment, so that the glue dispensing operation and the curing operation for the second time are respectively completed. So can realize the purpose of solidifying to the point of two sides of LCD screen terminal.

2. the overturning structure is simple, and the positioning is accurate;

3. the work efficiency is high, has saved the manpower.
