Then, the pressing cylinder 112 is controlled to drive the clamping jaw push rod 109 to move, so that the clamping jaw pressing block 108 swings around the first rotating shaft 106, the clamping jaw pressing block 108 and the first rotating shaft 106 form a labor-saving lever, the pressing force can be increased, at the moment, the bottom of the clamping jaw pressing block 108 presses the movable clamping jaw 104 and pushes the movable clamping jaw downwards, the rubber pad 113 located inside the movable clamping jaw 104 presses the clamping jaw bottom plate 101 in a pressing mode, at the moment, the clamping jaw is in a clamping jaw closing state, and the compression spring 118 is compressed. At this time, the transfer film 3 is held in the gap between the rubber pad 113 and the jaw base plate 101, and the transfer film 3 is clamped. Obviously, before completely flattening transfer film 3, hold-down cylinder 112 is in operation, i.e. transfer film 3 is clamped.

Further, in the self-adaptive film pulling assembly corresponding to the film pulling and flattening of the transfer film 3, as shown in a cross-sectional view a-a in fig. 3, the first elastic member is disposed on a side of the fixing member 117 facing away from the propulsion cylinder 1, and the self-adaptive film pulling assembly may further include an adjustment cavity 110, a push block 115, and a pressing member (a pressing screw 116). In the preferred embodiment, the first resilient member is preferably a rectangular spring 114. Of course, besides the rectangular spring 114, it can be provided in other forms of elastic member, such as a tension spring, according to the actual requirement, as long as the compression and recovery functions are satisfied.

The adjusting cavity 110 is disposed on the film drawing main board 2, connected to the film drawing main board 2, and a chamber for accommodating the rectangular spring 114 is disposed on a side of the adjusting cavity facing the fixing member 117, so that one end of the rectangular spring 114 is accommodated in the chamber and abuts against a side of the fixing member 117 away from the propulsion cylinder 1.

In actual arrangement, the fixing member 117 may be fixedly connected to the jaw bottom plate 101, one side of which is in abutting fit with the end of the output shaft of the propulsion cylinder 1, and the other side of which is in abutting fit with the end of the rectangular spring 114 of the adaptive film-drawing assembly; in this manner, by pushing the cylinder 1 and the rectangular spring 114 respectively, displacement control of the jaw base plate 101 can be realized. Further, the deformation direction of the rectangular spring 114 is parallel to the driving direction of the driving mechanism; and/or the output shaft of the drive mechanism acts on the fixing 117.

Further, a pressing member is disposed on the adjusting cavity 110, and an end of the pressing member abuts against an end of the first elastic member embedded in the cavity, so that the adaptive film pulling assembly can adjust an initial elastic force of the first elastic member by adjusting a position of the pressing member. Preferably, a push block 115 is arranged in the chamber of the adjustment chamber 110 corresponding to one end of the rectangular spring 114 facing away from the fixing piece 117, and a hold-down screw 116 is arranged on the adjustment chamber 110 corresponding to the push block 115, so that the position of the push block 115 in the chamber can be adjusted by the hold-down screw 116. In a preferred embodiment, the hold-down screw 116 compresses the rectangular spring 114 for a certain distance during installation and then fixes the rectangular spring 114, and the hold-down screw 116 is used to control the compression amount of the rectangular spring 114 within a required range during initial installation, so that the transfer film 3 can be flattened in a self-adaptive manner, and the jaw assembly does not displace greatly after the transfer film 3 is flattened, thereby causing the transfer film 3 to be damaged by pulling.

As shown in fig. 2, the fixing member 117 is located opposite to the propulsion cylinder 1. When the propulsion cylinder 1 pushes the fixing piece 117 to move towards the rectangular spring 114, the other end of the rectangular spring 114 is fixed by the pushing block 115, so that the rectangular spring 114 is compressed in the process of pushing the fixing piece 117 by the propulsion cylinder 1, and the compression energy storage is completed. After the clamping jaw assemblies clamp the transfer film 3 and push the air cylinder 1 to retract into the air cylinder shaft, because the pushing air cylinder 1 does not provide an acting force for compressing the rectangular spring 114 any more, the rectangular spring 114 starts to release energy for restoration, so that the rectangular spring 114 pushes the fixing piece 117 to move towards a direction away from the transfer film 3, and as the compression amount of the rectangular spring 114 is gradually reduced, the distance between the fixing piece 117 and the pushing block 115 is increased, and because the fixing piece 117 is fixedly connected with the clamping jaw bottom plate 101, the two clamping jaw assemblies respectively clamp one lateral side of the transfer film 3 and move towards a direction away from the transfer film 3, so that the transfer film 3 is pulled outwards. In the process of the back displacement of the two clamping jaw assemblies, the transfer printing film 3 has a moving space due to the existence of folds, and after the folds of the transfer printing film 3 are eliminated, the clamping jaw assemblies are not displaced any more due to the existence of the tension of the transfer printing film 3.

Obviously, in actual arrangement, the distance of the back displacement of the clamping jaw assembly depends on the size of the folds on the film, and the film pulling force is provided by the rectangular spring 114 when the transfer film 3 is flattened. Therefore, in actual use, it is preferable that the compression deformation amount of the rectangular spring 114 is controlled to an appropriate range by the hold-down screw 116 in advance so that the rectangular spring 114 does not undergo a large displacement after the wrinkle of the transfer film 3 is removed.

Specifically, in the preferred embodiment, the propulsion cylinder 1 is used to provide driving force to the gripper assembly to move the gripper assembly to the direction close to the transfer film 3, and the propulsion cylinder 1 is also used to cooperate with the adaptive film drawing assembly to compress the rectangular spring 114 in the adaptive film drawing assembly when the propulsion cylinder 1 is close to the transfer film 3 so as to achieve adaptive flattening of the film when the propulsion cylinder 1 retracts into the cylinder shaft.

In more detail, taking the view shown in fig. 1 as the front area of the main drawing film board 2, the area where the transfer film 3 is actually fed is the back area of the main drawing film board 2, and the clamping jaw assembly is correspondingly disposed in the back area. Correspondingly, in order to ensure that the transfer printing film 3 can be uniformly adsorbed on the back area of the film drawing main board 2 after being fed, the subsequent process processing is facilitated; in the preferred embodiment, a suction component is provided on the back of the stretch film mother board 2, as shown in fig. 4. The film-shaped material feeding device comprises transverse adsorption areas which are distributed on the two transverse sides of a film-shaped material feeding path area (such as a hollow-out area) formed between the two clamping jaw assemblies and/or longitudinal adsorption areas which are distributed on the two longitudinal sides (feeding direction) of the film-shaped material feeding path area (such as the hollow-out area) formed between the two clamping jaw assemblies. At the same time, the lateral suction area forms an inclination with the horizontal plane, corresponding to the inclination between the movable jaw 104 and the jaw base plate 101. Through the setting of above-mentioned adsorption component, can be in advance with rendition membrane 3 plastic, the clamping jaw subassembly of being convenient for centre gripping rendition membrane 3's horizontal both sides better. During actual work, the adsorption component adsorbs the transfer film 3 before the clamping jaw component pulls the film, and as an auxiliary use function, after the clamping jaw component clamps the film, the adsorption component stops adsorbing.

For the membrane flattening structure in the preferred embodiment, the membrane flattening structure is suitable for various scenes needing to flatten the membrane, such as flattening the membrane in the processing process or flattening the membrane when detecting the morphology of the membrane, and due to the self-adaptive flattening design, the control precision is high, and the flattening effect is good. Meanwhile, when the film flattening structure in the preferred embodiment is designed, no protrusion is arranged at the bottom of the structure, so that the free feeding of film-shaped materials and the free layout of the bottom of the machine table are ensured.
