[0036] like Figure 1-2As shown, the transport platform 203 includes a frame 206 that can accommodate the pallet 4 and a sliding vertical plate 207; one end of the sliding vertical plate 207 is fixedly connected to the frame 206, and the other end is slidably connected to the X-axis linear drive module 204; support assemblies 208 are provided on opposite sides of the frame 206; the support assembly 208 includes a support frame 209 that supports the pallet 4 and a third drive mechanism 210 that drives the support frame 209 to rotate; the third drive mechanism is a rotating cylinder; the support frame 209 is in a "Z" shape or an "L" shape; the third drive mechanism 210 is fixed on the frame 206; grooves for the support frame 209 to be inserted are provided on opposite sides of each pallet 4, so that the support frame can support the upper layer of pallets.
[0037] When loading, the transport platform moves to the top of the loading area, the support frame rotates outside the frame, the pallet in the loading area moves upward onto the frame, the sensor detects that the pallet has entered the frame, and the third drive mechanism drives the support frame to rotate inside the frame to hold the pallet, and under the drive of the X-axis linear drive module, drives the transport platform to move to the unloading area, the bottom plate of the unloading area moves upward, and the third drive mechanism drives the support frame to move outside the frame to release the pallet, and places the pallet in the unloading area to complete the unloading; the transport platform moves again to the top of the loading area to start a new round of automatic loading and unloading and the cycle continues; the mechanism uses mechanization instead of manual loading or taking, has a high degree of automation, and can work continuously, which not only speeds up the efficiency of loading and unloading, but also reduces the workload of the staff, saving time and effort.
[0038] like Figure 1-2 As shown, both the loading area 201 and the unloading area 202 include guide posts 211 for positioning the pallets 4. The guide posts 211 are fixed on the workbench 1; there is a certain distance between the guide posts and the frame; the total height of the pallets stacked in the guide posts is not greater than the height of the guide posts; the pallets are kept in a specific area and will not move easily during transportation, thereby improving the efficiency of loading and unloading and stably transporting the pallets, greatly saving time.

At least a portion of the second limiting components 213 protrudes from the bottom surface of the frame 206; the bottom of the second limiting components 213 is an outwardly turned arc structure; the accuracy of the frame positioning the tray is improved.
[0042] like Figure 3 As shown, the NG push rod assembly 108 includes a first mounting frame 113 fixedly connected to the OK discharging mechanism 103; a push rod 114 and a fifth driving mechanism 115 for driving the push rod 114 to extend and retract toward the NG discharging mechanism 108 are provided on the first mounting frame 113; the NG discharging mechanism 108 includes a second mounting frame 116 fixedly connected to the OK discharging mechanism 103; a sliding inclined plate 117 cooperating with the push rod 114 on the second mounting frame 116, and the sliding inclined plate 117 is arranged to tilt downward from one end of the second mounting frame 116; a plurality of rolling belts consisting of a plurality of rolling wheels 118 are arranged in parallel on the sliding inclined plate 117, so that the NG carrier can slide down smoothly.
[0043] The automatic locking machine has a high degree of automation. The carrier is manually placed in the feeding mechanism, and the conveyor belt drives the carrier to move to the designated position. The manipulator removes the workpiece from the feeding mechanism, moves the workpiece to the upper side of the lower CCD camera for photo positioning and position correction, and places the workpiece at the designated position of the screw hole of the carrier. The conveyor belt drives the carrier to move to one end of the transportation mechanism, and the first CCD camera takes the first photo and positions the screw hole position of the carrier. The locking mechanism moves to one side of the carrier to lock the workpiece and the carrier, and the conveyor belt drives the carrier to the other end of the transportation mechanism. The second upper CCD camera takes the second photo of the locked carrier and detects and judges; if it is determined to be an OK carrier, the OK carrier moves along the assembly line to the unloading position of the OK discharging mechanism; if it is determined to be an NG carrier, the NG carrier stays on one side of the NG discharging mechanism, and the second driving mechanism raises the NG carrier to the height of the push rod assembly, and the push rod assembly pushes the NG carrier out of the NG discharging mechanism.
