[0024] During operation, a pressure-sensitive adhesive spraying mechanical arm with a fault detection function in the above technology, since the monitoring probe is fixed on the support plate by a support frame and its position is fixed, it is inevitable that a blind spot will be generated during the monitoring process. The structural design of the moving mechanism realizes the function of facilitating the movement of the monitoring probe 20 on the bottom plate 25. When the position of the monitoring probe 20 is to be moved, the driving motor 36 is first used to drive the driving gear 29 to rotate, and the driving gear 29 is meshed with the internal gear 26. Therefore, the driving gear 29 will drive the internal gear 26 to rotate inside the bottom plate 25. The internal gear 26 is fixed with a base 22, and the base 22 will make a circular motion along the through groove 23, thereby driving the monitoring probe 20 fixed on the support frame 21 to move on the bottom plate 25, so that the monitoring probe 20 can better monitor the mechanical arm body 1 during operation, wherein the internal gear 26 is ensured to rotate stably by the sliding of the fixed retaining ring 30 in the groove 31 on the internal gear 26, and the support plate 24 is fixed on the fixed plate 38 by the support seat 27 fixed at the bottom end.

[0025] Furthermore, an annular groove 32 is formed at the bottom end of the inner gear 26, and a plurality of pulleys 33 are welded and fixed on the inner wall of the annular groove 32, and the pulleys 33 are in contact with the top end of the fixing plate 38;

[0033] Furthermore, the interior of the support frame 21 is hollow, and the support frame 21 is made of aluminum alloy;

[0034] When working, the support frame 21 is hollow in design and made of aluminum alloy to reduce the weight of the support frame 21 itself, thereby reducing the weight that the internal gear 26 needs to bear, so that the internal gear 26 can drive the base 22 and the support frame 21 to move.

[0035] Working principle: In the prior art, a pressure-sensitive adhesive spraying robot arm with a fault detection function has a fixed position because the monitoring probe is fixed on the support plate by a support frame. Therefore, blind spots are inevitable during the monitoring process. In this case, a motion robot arm with a self-diagnosis function realizes the function of moving the monitoring probe 20 on the bottom plate 25 through the structural design of the moving mechanism. When the position of the monitoring probe 20 is to be moved, the driving motor 36 is first used to drive the driving gear 29 to rotate, and the driving gear 29 is meshed with the internal gear 26. Therefore, the driving gear 29 will drive the internal gear 26 to rotate inside the bottom plate 25. The internal gear 26 is fixed with a base 22, and the base 22 will make a circular motion along the through groove 23, thereby driving the monitoring probe 20 fixed on the support frame 21 to move on the bottom plate 25, so that the monitoring probe 20 can better monitor the robot arm body 1 when it is working. The internal gear 26 is fixed by the sliding of the retaining ring 30 in the groove 31 to ensure the stable rotation of the internal gear 26. The support plate 24 is fixed on the fixed plate 38 through the support seat 27 fixed at the bottom end.
