[0033] To solve the problem of lack of fixation of the anti-falling disc in the prior art, which causes insufficient actual anti-falling effect of the filter disc in film coating transportation, the utility model provides a mechanical arm structure based on an anti-falling disc of a film coating machine, which is provided with an opening in the carrier disc, which is in alignment with the protrusion at the bottom of the anti-falling disc, and first and second positioning pins are arranged on the two sides of the opening respectively, the second positioning pin can be driven to move up and down by a driving module, and the diameter of the second positioning pin gradually increases from top to bottom. When the anti-falling disc is placed on the carrier disc, the protrusion at the bottom of the anti-falling disc triggers the trigger sensor of the driving module, the driving module drives the second positioning pin to rise, and the anti-falling disc can be automatically positioned and clamped between the first and second positioning pins, thereby effectively fixing the anti-falling disc and reducing the risk of falling of the anti-falling disc due to interference during transportation, and the diameter of the second positioning pin is smaller at the top and larger at the bottom, which can be compatible with various anti-falling discs of different sizes due to processing errors, thereby ensuring use reliability.

[0034] Specifically, please refer to Figures 1 to 4 The mechanical arm structure of the embodiment mainly comprises a carrier disc 1, first positioning pins 2 arranged on the carrier disc 1, and a movable limiting assembly 4 arranged on the carrier disc 1, the movable limiting assembly 4 comprises a second positioning pin 410 and a driving module, and the driving module can drive the second positioning pin 410 to move up and down.

[0035] The first positioning pins 2 are arranged in two, corresponding to one side of the anti-falling disc 2, the second positioning pin 410 corresponds to the other side of the anti-falling disc 2, and three-point positioning is formed as a whole, thereby limiting and fixing the anti-falling disc 2. The size of the anti-falling disc 2 is larger than that of the filter disc, for example, in the embodiment, three filter discs can be placed on the anti-falling disc 2, and the distance between the filter disc and the edge of the anti-falling disc 2 is sufficient, thereby effectively reducing the risk of falling of the filter disc from the anti-falling disc 2.

[0036] The opening in the carrier plate 1 is aligned with the protrusion at the bottom of the anti-falling plate 2. The movable limiting assembly 4 is mainly arranged below the carrier plate 1. The driving module of the movable limiting assembly 4 includes a trigger sensor 44, a driving motor 45 and a transmission mechanism. The trigger end of the trigger sensor 44 extends into the opening area of the carrier plate 1. The trigger sensor 44 is in communication connection with the driving motor 45. The transmission mechanism is in transmission connection with the second positioning pin 410 and the driving motor 45. When the anti-falling plate 2 is placed on the carrier plate 1, the protrusion at the bottom of the anti-falling plate 2 is pressed on the trigger sensor 44. The trigger sensor 44 triggers the driving motor 45 to output power. The output power of the driving motor 45 is transmitted to the second positioning pin 410 through the transmission mechanism, so as to drive the second positioning pin 410 to rise above the upper surface of the carrier plate 1 until the side wall of the second positioning pin 410 contacts the anti-falling plate 2. According to the inclined side wall of the second positioning pin 410, the anti-falling plate 2 is driven to deviate from the first positioning pin 3 until the anti-falling plate 2 contacts and is limited by the first positioning pin 3 and the second positioning pin 410, thereby achieving fixation.

[0037] After the anti-falling plate 2 contacts the first positioning pin 3 and the second positioning pin 410, the anti-falling plate 2 can be lifted on one side, so that the protrusion at the bottom of the anti-falling plate 2 is separated from the trigger sensor 44. The driving motor 45 stops outputting and is locked. The second positioning pin 410 can be locked at the current height. Therefore, after the anti-falling plate 2 is fixed by clamping, the second positioning pin 410 can be automatically stopped and locked, thereby ensuring the horizontal characteristics of the anti-falling plate 2.

[0038] In the embodiment, two first positioning pins 3 are arranged. In practice, three or more first positioning pins 3 can be arranged in line. The first positioning pins 3 are arranged on both sides of the opening position of the carrier plate 1 opposite to the second positioning pin 410.

So that the transmission rod 49 can move up and down along the guide rod 7 through the moving block 8, while avoiding the phenomenon of rotation and revolution, so that when the screw rod 48 rotates, the transmission rod 49 can be driven to move up and down, and then drive the second positioning pin 410 to move up and down.

[0042] The bottom end of the guide rod 7 is also provided with a limiting block 9, the size of the limiting block 9 is greater than the hole diameter of the assembly hole of the moving block 8 to the guide rod 7, which can limit the lower limit of the moving block 8, avoid the moving block 8 from the guide rod 7, and then protect the rotation limiting effect of the transmission rod 49.

[0043] The second positioning pin 410 needs to be vertically lifted and needs to occupy a certain installation space, in order to reduce the influence of the setting of the movable limiting component 4 on the vertical size increment of the mechanical arm structure, in the embodiment, the transmission gear set includes a helical gear set, specifically including a first helical gear 46 and a second helical gear 47, the first helical gear 46 is coaxially connected with the output shaft of the driving motor 45, and the second helical gear 47 is coaxially connected with the screw rod 48, so that the driving motor 45 can be arranged on the side of the screw rod 48, realizing horizontal layout and reducing the height of the movable limiting component 4.
