The turntable rotates another 45° to proceed to the next process. After completing all processes, the carrier loading and unloading mechanism removes the finished product and the carrier from the turntable.

[0054] (1) Assembly line mechanism 11

[0055] The assembly line mechanism includes a conveying line 111, a blocking lifting mechanism, a lifting rotating mechanism 113, a feeding sensing mechanism, an NG material unloading line 115, an OK material unloading line, and an NG side-pushing lifting mechanism 116. The conveying line is arranged on the large plate of the lower frame, and can simultaneously convey the carrier to be processed and the finished product (the front part of the conveying line is used to convey the carrier to be processed, and the rear part is used to convey the finished product). The conveying line is provided with a plurality of feeding sensing mechanisms and a plurality of blocking lifting mechanisms, and the lifting rotating mechanism is arranged below the conveying line. The NG material unloading line and the OK material unloading line are connected to the conveying line, and the NG side-pushing lifting mechanism is located on the side of the conveying line to push the NG product into the NG material unloading line.

[0056] In this embodiment, there are 4 groups of blocking and lifting mechanisms, which are: the first blocking and lifting mechanism 1121, the second blocking and lifting mechanism 1122, the third blocking and lifting mechanism 1123, and the fourth blocking and lifting mechanism 1124. The first three groups of blocking and lifting mechanisms are set at the material loading position of the conveying line, and the fourth blocking and lifting mechanism is set at the NG material discharging position; there are 3 groups of feeding sensing mechanisms, which are located at the material loading position of the conveying line, which are: the first feeding sensing mechanism 1141, the second feeding sensing mechanism 1142, and the third feeding sensing mechanism 1143. The lifting and rotating mechanism is located between the second blocking and lifting mechanism and the third blocking and lifting mechanism. Among them, the feeding sensing mechanism can use a through-beam sensor.

[0057] The structure of each group of blocking and lifting mechanisms can be the same, and specifically can include: a blocking and lifting cylinder, a blocking and lifting cylinder fixing seat, a lifting block, and a blocking block. The blocking and lifting cylinder is fixed to the large plate through the blocking and lifting cylinder fixing seat, and the output end of the blocking and lifting cylinder is connected to the blocking block through the lifting block, and drives the blocking block to move up and down.

[0058] When the through-beam sensors 1 and 2 sense the presence of material at the same time, the first lifting and blocking mechanism lifts up to stop the carrier from flowing in; when there is no material at the through-beam sensor 2, material loading continues; when there is material at the position of the through-beam sensor 3, the second lifting and blocking mechanism lifts up to stop the flow in, and at the same time the third lifting and blocking mechanism lifts up to stop the carrier.

[0059] The lifting and rotating mechanism lifts the carrier to a certain height, and then rotates the direction of the carrier so that the transfer and loading mechanism can clamp the load and unload materials (the transfer mechanism puts the carrier to be processed into the turntable, and the processed carrier is returned to the conveyor line. OK finished products flow directly into the discharge module, and NG products flow into the NG unloading position).

[0060] The lifting and rotating mechanism includes a lifting cylinder for loading and unloading materials, a lifting cylinder fixing plate for loading and unloading materials, a rotating cylinder for loading and unloading materials, a connecting plate for the rotating cylinder for loading and unloading materials, and a carrier support plate.

The head end of the unloading rack is connected to the conveying line, and the end extends to the unloading port, and a buffer pad is arranged on the end.

[0062] OK, the carrier flows from the conveyor line into the discharge module. The discharge module is equipped with a smooth strip and tilted at a certain angle. When the carrier is put in, it will slide down in the tilted direction. When the sensor detects that there is material at the discharge port, the conveyor line will stop conveying and remind manual material removal.

The NG side-pushing cylinder is arranged on the side of the fourth blocking and lifting mechanism through the side-pushing cylinder fixing plate. The side-pushing cylinder drives the jig pushing block to move forward and backward. The NG carrier lifting cylinder is located below the conveying assembly line and drives the NG carrier lifting plate to rise, so that the NG carrier is separated from the conveying assembly line. When the NG carrier flows to the NG discharging position, the fourth blocking and lifting mechanism stops, and the NG carrier lifting cylinder lifts the carrier to a certain height.
