It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures".

[0029] like Figure 5 and Figure 6 As shown, the inspection table frame locking mechanism includes a limit block 5.1, a third clamp 5.2 and a clamp mounting block 5.3, the limit block is fixed at the bottom of the flip table support frame, the third clamp is fixed to the bottom of the fixed frame through the clamp mounting block, and the movable end of the third clamp cooperates with the limit block. The inspection table frame locking mechanism can realize the inspection table to be firmly fixed in the inspection position to prevent the inspection table from moving.

[0030] like Fig. 9 As shown, the anti-flip mechanism of the flip table foot pedal includes a stop plate 6.1, a stop pin limiter 6.2, a spring 6.3, a stop pin mounting seat 6.4, a stop pin 6.5, a hinge 6.6, a foot pedal 6.7, a foot pedal rotating shaft 6.8 and a mounting seat 6.9; the stop plate is hinged to the upper part of one side of the flip table support frame, the stop plate is provided with a slot, the stop pin limiter is located at the lower part of the stop plate and cooperates with it, the stop pin is slidably matched with the stop pin mounting seat, the stop pin mounting seat is fixed to the side of the flip table support frame, the spring is sleeved on the stop pin and is located between the stop pin mounting seat and the stop pin limiter, the lower end of the stop pin is hinged to the middle part of the foot pedal through the hinge, and the other end of the foot pedal is hinged to the mounting seat through the foot pedal rotating shaft.

And the proximity switch signal can enable the manipulator to automatically identify whether there are panels on the inspection table to avoid collisions.

[0032] Working principle:

[0033] 1. Manually step on the pedal 6.7 to drive the stop pin 6.5 downward through the hinge 6.6, releasing the stop plate 6.1 to make it free. Manually rotate the turntable to a horizontal position, loosen the pedal 6.7, lock the stop plate 6.1, and fix the turntable so that it cannot rotate. This is the first anti-rotation measure.

[0034] 2. Manually open the first handle 1.2 and the second handle 1.7 in sequence, so that the first clamp 1.1 and the second clamp 1.6 are opened. When the first handle 1.2 is opened, the connecting rod 1.4 is inserted into the fixed stop hole, so that the turntable is fixed and cannot rotate. This is the second anti-rotation measure. When the second handle 1.7 is opened, the baffle 1.5 is rotated to block the connecting rod 1.4, so that the connecting rod 1.4 cannot move and will not fall out of the stop hole.

[0035] 3. Manually push the inspection table to the automatic manipulator's lowering position, operate the button, so that the clamp 5.2 is firmly clamped on the limit block 5.1, so that the inspection table cannot be moved, which is convenient for the automatic manipulator to place the parts. After the manipulator places the parts, manually pull the first handle 1.2 and the second handle 1.7 into place in sequence, so that the first clamp 1.1 and the second clamp 1.6 are clamped in place to fix the plate. At this time, the turntable can be rotated by stepping on the foot pedal 6.7, but the plate will not fall.

[0036] 4. Press the button manually, the clamp 5.2 opens, and the inspection table is manually pulled out to inspect the panel.

[0037] 5. Repeat step 1 and manually inspect the front and back sides of the panel. After the inspection, manually restore the turntable to a horizontal position and push the inspection table to the automatic robot lowering position again. Manually repeat step 2. At this time, the panel is in a free state, but the turntable will not rotate. The panel can be grabbed by the robot but will not fall.

[0038] At this time, the signals of the first coupler 1.1 and the second coupler 1.2 are connected, and through the proximity switch 1.3, the robot senses the presence of a plate on the turntable and automatically grabs the plate.

[0039] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
