For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the embodiments of the present utility model will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a film tearing mechanism according to an embodiment of the present utility model.

In one aspect, and as shown in connection with fig. 1, a film tearing mechanism comprises: an adsorption assembly 1, a clamping jaw assembly 2 and a movement assembly 3.

The adsorption component 1 is used for adsorbing the film layer 001 to be torn by utilizing negative pressure; the clamping jaw assembly 2 is connected to one side of the adsorption assembly 1, and the clamping jaw assembly 2 is used for clamping the film layer 001 to be torn on the surface of the adsorption assembly 1.

The clamping jaw assembly 2 and the adsorption assembly 1 are integrally connected with the movement assembly 3, and the movement assembly 3 is used for driving the clamping jaw assembly 2 and the adsorption assembly 1 to move.

According to the film tearing mechanism, the film layer 001 to be torn is adsorbed by the adsorption component 1, the clamping jaw component 2 clamps the film layer 001 to be torn on the surface of the adsorption component 1, the motion component 3 drives the adsorption component 1 and the clamping jaw component 2 to move, on one hand, the power for tearing the film layer 001 to be torn can be provided, and on the other hand, the direction and the position of the adsorption component 1 and the clamping jaw component 2 can be changed, so that the film tearing mechanism can be suitable for different types of working scenes, and the application range of the film tearing mechanism is improved.

Illustratively, the film layer 001 to be torn includes, but is not limited to, a release paper film on the surface of an adhesive material, a protective film on the surface of an electronic component, a light shielding film, and the like.

In other possible implementation manners, the film layer 001 to be torn includes a handle portion 002, the handle portion 002 protrudes to the outside of the film layer 001 to be torn, the adsorption component 1 adsorbs the handle portion 002 by utilizing negative pressure, the clamping jaw component 2 clamps the handle portion 002 on the surface of the adsorption component 1, and then the handle portion 002 is pulled by utilizing the driving of the motion component 3, so that the whole film layer 001 to be torn is torn.

As shown in connection with fig. 2, in some embodiments, the adsorption assembly 1 includes a first support block 11 and a vacuum generating unit 12; the top surface of the first supporting block 11 is provided with a suction hole 111, and the suction hole 111 extends into the first supporting block 11 and is connected with a vacuum generating unit 12 positioned at one side of the first supporting block 11.

The dyestripping mechanism of this embodiment utilizes vacuum generator to produce negative pressure, will wait to tear the rete 001 and adsorb and fix at the first supporting shoe 11 top surface that has adsorption hole 111 to be convenient for clamping jaw subassembly 2 will wait to tear the rete 001 and compress tightly fixedly, and then utilize the power that motion component 3 provided to tear the rete 001.

In some possible implementations, the vacuum generator uses a positive pressure air source to generate negative pressure, with efficient, clean, economical, small vacuum components, which makes it easy and convenient to obtain negative pressure where there is compressed air, or where positive and negative pressure are simultaneously required in a pneumatic system.

In some embodiments, the top surface of the first supporting block 11 is provided with a flexible layer (not shown in fig. 1) which is arranged around the suction hole 111 and is used for clamping the film layer 001 to be torn up and down with the clamping jaw assembly 2.

Because the thickness of most of the film layers 001 to be torn is small, if two hard surfaces are used for compaction, the problem that the film layers cannot be effectively fixed may occur. However, if a larger pressing force is used, the film 001 to be torn may be crushed, which is more unfavorable for tearing the whole film 001 to be torn.

Therefore, in the film tearing mechanism of this embodiment, the flexible layer is arranged on the top surface of the first supporting block 11, and when the clamping jaw assembly 2 is pressed downwards, the flexible layer is extruded to deform, and the film layer 001 to be torn is firmly pressed and fixed.

Illustratively, the flexible layer includes, but is not limited to, a rubber layer, a silicone layer, a foam layer, and the like.

As shown in connection with fig. 2, in some embodiments, the jaw assembly 2 includes a jaw member 21, a first driver 22; jaw member 21 includes a jaw body 211, a working portion 212, a first hinge 213 and a second hinge 214.

Working portion 212 and second hinge portion 214 are located at opposite ends of jaw body 211, respectively, and first hinge portion 213 is located on jaw body 211 between first working portion 212 and second hinge portion 214.

In the film tearing mechanism of the present embodiment, the first driver 22 provides power for the clamping jaw main body 211 to drive the clamping jaw main body 211 to rotate around the first hinge shaft, so that the working portion 212 reaches and is far away from the top surface of the first supporting block 11, and when the working portion 212 approaches to the top surface of the first supporting block 11, the working portion 212 is pressed on the top surface of the first supporting block 11.

In some possible implementations, referring to fig. 1, the first supporting block 11 is provided with a through groove 114, and the clamping jaw main body 211 is penetratingly arranged in the through groove 114, so that the longitudinal positioning can be obtained, and the longitudinal thickness of the film tearing mechanism is reduced, and the clamping jaw main body 211 is positioned in the through groove 114, so that the working portion 212 and the top surface of the first supporting block 11 can be aligned exactly, and the working reliability of the clamping jaw assembly 2 is improved.

In some possible implementations, the first driver 22 includes, but is not limited to, an electric driver, a hydraulic driver, a pneumatic driver, and the like.

As shown in connection with fig. 3, in some embodiments, jaw body 211 includes a first extension 2111 and a second extension 2112, one end of first extension 2111 is connected to one end of second extension 2112, the other end of first extension 2111 is provided with working portion 212, the other end of second extension 2112 is provided with second hinge 214, and first hinge 213 is located on either first extension 2111 or second extension 2112; the first extension 2111 and the second extension 2112 meet at an angle greater than 0 and less than 180 °.

The first extension portion 2111 and the second extension portion 2112 of the jaw main body 211 of the present embodiment are connected at an angle of more than 0 and less than 180 °, so that the first driver 22 drives the second hinge portion 214, and can drive the working portion 212 to perform clamping and opening actions.

Illustratively, the grip of the first extension 2111 and the second extension 2112 is 90 °.

As shown in connection with fig. 4-7, in some embodiments, the first support block 11 is provided with a chute 112, and the first hinge 213 is movably connected to the chute 112 by a first pin 2131, and the chute 112 extends in a direction approaching and separating from the top surface of the first support block 11.

The first hinge 213 is located on the second extension 2112; the vertical distance between the upper end of the chute 112 and the top surface of the first supporting block 11 is smaller than the vertical distance between the first hinge part 213 and the working part 212; the vertical distance between the lower end of the chute 112 and the top surface of the first supporting block 11 is greater than the vertical distance between the first hinge portion 213 and the working portion 212.

When the first pin shaft 2131 is positioned at the upper end of the chute 112, the working portion 212 can move above the top surface of the first supporting block 11; when the first pin 2131 is located at the lower end of the chute 112, the working portion 212 can be pressed against the top surface of the first supporting block 11.

With the chute 112 and the first pin 2131 of the present embodiment, the rotation axis of the jaw main body 211 is provided, and the first pin 2131 slides up and down in the chute 112, so that the jaw main body 211 obtains additional up and down movement space, and the working portion 212 can realize a more complex movement route.

As shown in fig. 5, the first pin 2131 is located at the upper end of the chute 112, the working portion 212 is located above the top surface of the first supporting block 11, and the working portion 212 can move above the film 001 to be torn along with the further rotation of the clamping jaw main body 211, so that the working portion 212 can be effectively prevented from interfering with the film 001 to be torn, and the film 001 to be torn is pushed away.

As another example, as shown in fig. 6, the first pin 2131 is located at the lower end of the chute 112, and the working portion 212 is pressed against the top surface of the first supporting block 11 and has a significant descending movement, so that the film 001 to be torn is pressed and fixed on the top surface of the first supporting block 11.

As shown in connection with fig. 4-7, in some embodiments, the first support block 11 is further provided with a second pin 114, the second pin 114 abutting the jaw body 211 between the first hinge 213 and the second hinge 214; when the first driver 22 drives the second hinge 214 to move upward, the second pin 113 is blocked above the jaw main body 211, the first hinge 213 moves downward, and the first pin 2131 moves to the lower end of the chute 112.

When the second hinge portion 214 moves upwards, the second pin 113 blocks the upper portion of the clamping jaw main body 211, the second pin 113 plays a role of leverage, the first hinge portion 213 is pushed to move downwards, and the first pin 2131 moves to the lower end of the sliding groove 112, so that the whole clamping jaw main body 211 is driven to move downwards, and the working portion 212 can realize a more complex movement route.

For example, as shown in fig. 4, at this time, the working portion 212 is withdrawn out of the first supporting block 11, and the height of the working portion 212 is significantly lower than that of the first supporting block 11 because the first pin 2131 is located at the lower end of the chute 112. Therefore, the highest point of the whole mechanism is the top surface of the first supporting block 11, so that the first supporting block 11 is very favorable to be close to the film layer 001 to be torn as much as possible, even if the film layer 001 to be torn is not tilted, the film layer 001 to be torn is only flat on the surface of a device, and the film layer 001 to be torn can be adsorbed by the adsorption holes 111 after the top surface of the first supporting block 11 is close to, so that the film layer 001 to be torn is tilted, and the working part 212 can extend in.

Thus, the dyestripping mechanism of this embodiment can solve the problem that the film layer 001 of waiting to tear that does not have perk can't carry out automatic tearing.

In some possible implementations, the state shown in fig. 4 is an open state of the dyestripping mechanism, the state shown in fig. 5 is a semi-open state of the dyestripping mechanism, and the state shown in fig. 6 is a clamped state of the dyestripping mechanism. When the dyestripping mechanism works, the dyestripping mechanism can be sequentially switched into an open state, a semi-open state, a clamping state, a semi-open state and an open state.

As shown in connection with fig. 2 and 7, in some embodiments, the jaw assembly 2 further includes an elastic member 23, one end of the elastic member 23 is connected to the first support block 11, and the other end is connected to the jaw main body 211 between the first hinge portion 213 and the working portion 212, and the elastic member 23 applies a tension force between the first support block 11 and the jaw main body 211.

When the first driver 22 drives the second hinge 214 to move downward, the elastic member 23 drives the first hinge 213 to move upward, and the first pin 2131 moves to the upper end of the chute 112.

In the film tearing mechanism of the present embodiment, when the second hinge portion 214 moves downward, the elastic member 23 drives the first hinge portion 213 to move upward, and the first pin 2131 moves to the upper end of the chute 112, so as to drive the entire clamping jaw main body 211 to move downward, thereby enabling the working portion 212 to implement a more complex movement route.

As shown in connection with fig. 1, in some embodiments, the motion assembly 3 includes a second support block 31 and a second driver 32; the first supporting block 11 is respectively connected with a second supporting block 31 and a second driver 32, and the second driver 32 is used for driving the first supporting block 11 to rotate relative to the second supporting block 31.
