[0031] An automatic edge and corner film pasting mechanism has the advantages of high speed, high efficiency, low risk factor and stable quality. Its structure includes a product seat 1, a product fixture 2 for placing and fixing a product 98 and a film 99, a film supporting mechanism 3, a pressing mechanism 5 and a film pasting mechanism 4.

[0032] The product fixture is arranged at the upper end of the product seat, the film supporting mechanisms are symmetrically arranged on the left and right sides of the product seat, the lower part of the pressing mechanism is arranged on both sides of the product seat, the film pasting mechanism is connected to the pressing mechanism, the film pasting mechanism is arranged above the product fixture and between the two oppositely arranged film supporting mechanisms, and the pressing mechanism drives the film pasting mechanism to move up and down to complete the film pasting and pressure maintaining operation.

[0033] The product jig 2 includes a base connecting plate 21 and a product profiling jig 22 . A product 98 is placed on the upper end of each product profiling jig 22 . When film pasting is required, a film 99 needs to be placed on the upper end surface of the product 98 .

[0034] The number of the film supporting mechanisms 3 is 4, and two film supporting mechanisms form a group. The two film supporting mechanisms in each group are respectively arranged on both sides of the product seat relative to each other, so that the film supporting mechanisms can hold up the film from both sides of the product, improve the stability of the film supporting and film sticking operations, prevent positional displacement between the film and the product, improve the accuracy of film sticking, and facilitate operation.

[0035] The film supporting mechanism 3 includes a base 31, a support plate 32, a transverse plate 33, a telescopic cylinder 34, a lifting cylinder 35, a supporting claw 36, an air pipe joint 37, and a vacuum hole 38. The support plate 32 is vertically arranged on the inner side of the base 31, and the transverse plate 33 is horizontally arranged on the upper end of the support plate 32. The telescopic cylinder 34 is arranged on the upper end of the transverse plate 33 and is connected to the supporting claw 36 to drive the supporting claw to move back and forth on the transverse plate. The lifting cylinder 35 is arranged on the inner side of the support plate 32 and is connected to the bottom of the transverse plate 33 to drive the transverse plate to move up and down. The air pipe joint 37 is arranged on the side of the supporting claw 36, and the top surface of the supporting claw is provided with a plurality of vacuum holes connected to the air pipe joint.

[0036] After the product 98 moves to the film-sticking position, the lifting cylinder adjusts the position of the horizontal plate so that the height of the supporting claw is lower than the height of the film; the telescopic cylinder 34 drives the supporting claw 36 to extend to the position directly below the film 99 on the product, and the lifting cylinder 35 rises, driving the supporting claw 36 to rise to support the film; when the film-sticking mechanism 4 descends to fit the edges and corners of the film, air is ventilated to the vacuum holes on the supporting claw 36 through the air pipe joint 37 to blow the film at other positions upward to prevent the film from sagging naturally and sticking to the product, thereby improving the film-sticking efficiency.

[0037] The pressing mechanism 5 includes a fixing seat 51 , a guide column 52 , a tensioning block 53 , a fixing plate 54 , a connecting plate 55 , and a lifting cylinder 56 .

[0045] One end of the guide shaft is fixedly connected to the sliding seat, and the other end is floatingly connected to the limiting seat to further play a role in motion guidance.

[0046] The spring surrounds the outer side of the guide shaft, and the spring is clamped between the limit seat and the sliding seat to play the role of resetting the sliding seat. When the film laminating mechanism descends to maintain the pressure film, the spring is compressed by force, and after the product is pressure-maintained, the blocking cylinder drives the push rod to descend to completely separate the three pressing claw assemblies, and the film laminating mechanism rises as a whole, and the blocking cylinder drives the push rod to rise, and the three pressing claw assemblies are reset by the spring force.

[0047] The support block 432 is arranged on the top surface of the upper base plate, the blocking cylinder is fixedly arranged on the support block, the output end of the blocking cylinder of the push rod is connected to the top of the push rod, the lower part of the push rod passes through the upper base plate and the lower base plate, and a plurality of guide slopes 439 are arranged on the bottom side wall of the push rod, and the bottom end of the guide slope extends downward and gradually approaches the middle.

The pressure claw assembly 42 is arranged on the bottom surface of the sliding seat, and the guide slope of the push rod drives the pressure claw assembly 42 to move back and forth along the guide rail through the sliding seat.

[0049] When the film laminating mechanism reaches above the product (at this time, the pressing claw assembly is aimed at the corners of the product), the lifting cylinder descends, driving the film laminating mechanism to descend as a whole, and using the pressing claw assembly to fit the film at the corners; after the film laminating is completed, the blocking cylinder drives the push rod to descend, and the guide slope on the push rod drives the pressing claw assembly to move outward along the guide rail through the sliding seat, thereby separating the pressing claw assembly from the product. At this time, the spring is in a compressed state; the lifting cylinder drives the film laminating mechanism to rise to ensure the integrity of the film; the blocking cylinder drives the push rod to rise, and the spring pushes the sliding seat to move inward for reset.

[0050] The pressing claw assembly 42 includes a guide block 421 , a connecting block 422 , a connecting groove 423 , a limiting step 424 , a floating portion 425 , a pressing claw spring 426 and a silicone pressure head 427 .

[0051] The guide block is connected to the sliding seat, a connecting groove is arranged in the guide block, and a limiting step is arranged on the side wall of the connecting groove.

[0052] The floating part is arranged at the top of the connecting block, and the floating part cooperates with the limiting step so that the connecting block can move up and down in the connecting groove to prevent the connecting block from falling out of the connecting groove downward. A pressure claw spring is arranged on the top of the floating part, and the top of the pressure claw spring is connected to the sliding seat to reset the connecting block and the pressure head.
