Description

Technical Field

[0001] This utility model relates to the field of film removal equipment for sheet materials, and in particular to a film tearing device and an automatic film removal device for automatic film removal equipment. Background Technology

[0002] In the field of sheet processing and application, to prevent scratches and contamination on the sheet surface during transportation, storage, or pre-processing, a protective film is usually applied to the sheet surface. When the sheet enters subsequent processes or the finished product application stage, this protective film needs to be removed using a film-cutting or film-removing device. Currently, the film-removing process is mainly done manually. Even when auxiliary film-removing equipment is used, the structure is relatively simple, generally consisting only of a film-removing base and a film-removing clamp. The film-removing clamp is directly fixed to the film-removing base. Some equipment, to adapt to the film removal needs of sheets of different thicknesses, adds a simple lifting component between the film-removing base and the film-removing clamp. However, this lifting component can only achieve linear displacement adjustment of the film-removing clamp along a direction perpendicular to the sheet surface and cannot change the clamping direction of the film-removing clamp itself. Film-tearing devices that cannot change the clamping direction can generally only tear the film at a fixed angle. When encountering boards with irregularly shaped films (such as films with curved or zigzag edges, or films that are not perpendicular to the board surface), the film-tearing fixture with a fixed clamping direction cannot adjust the tearing angle according to the contour and bonding angle of the irregular film. This results in uneven stress on the film during the tearing process, which can easily lead to film breakage and residue. In addition, to adapt to different film-tearing angle requirements, some production scenarios require manual disassembly and readjustment of the installation angle of the film-tearing fixture. This not only significantly reduces the continuous operation efficiency of automatic film removal equipment, but also makes it difficult to unify the precision of manual adjustment. This cannot meet the industrial production requirements of large-scale, high-precision board film removal, and is difficult to adapt to the automated and standardized production needs of modern board processing.

The film-tearing mechanism also includes a film-tearing floating elastic element, the top of which abuts against the film-tearing partition, and the bottom of which abuts against the top of the film-tearing rotating sleeve or the film-tearing movable rod.

[0008] As an improvement to the above solution, the film-tearing device for automatic film removal equipment further includes a film-tearing pipeline processing mechanism. The film-tearing pipeline processing mechanism includes a film-tearing slip ring and a film-tearing air pipe connector. The film-tearing slip ring is located at the top of the film-tearing connecting sleeve. The film-tearing partition and the upper part of the film-tearing connecting sleeve form a film-tearing air pipe receiving cavity. The film-tearing air pipe connector is fixed to the bottom of the film-tearing slip ring and located in the film-tearing air pipe receiving cavity. One end of the film-tearing air pipe connector is connected to an external air pipe through the film-tearing slip ring, and the other end of the film-tearing air pipe connector is connected to an internal film-tearing air pipe.

[0009] As an improvement to the above solution, the tearing film partition is provided with a tearing film communication hole in the middle, and the tearing film movable rod is provided with a tearing film inner rod hole inside. The tearing film inner rod hole is coaxially arranged with the tearing film communication hole. The tearing film air pipe receiving cavity and the tearing film floating cavity are connected through the tearing film communication hole. The tearing film inner air pipe passes downward through the tearing film communication hole and extends into the tearing film inner rod hole to communicate with the tearing film clamp.

[0010] As an improvement to the above solution, the tearing film partition is provided with a lower tearing film protrusion ring in the middle, the lower tearing film protrusion ring protrudes downward, the tearing film connecting hole is provided inside the lower tearing film protrusion ring, the top of the tearing film movable rod is provided with an upper tearing film protrusion ring, the upper part of the tearing film inner rod hole is provided inside the upper tearing film protrusion ring, the upper part of the tearing film floating elastic element is sleeved outside the lower tearing film protrusion ring, the lower part of the tearing film floating elastic element is sleeved outside the upper tearing film protrusion ring, and the tearing film inner air tube passes through the hollow part of the tearing film floating elastic element.

[0011] As an improvement to the above solution, the film-tearing clamp includes two film-tearing clamps symmetrically arranged at the bottom of the film-tearing clamp. The two film-tearing clamps can approach or move away from each other. Each film-tearing clamp includes a connecting section and an inclined section. The connecting section extends downward, and the inclined section is connected to the connecting section and extends downward at an incline. The opposite sides of the inclined sections of the two film-tearing clamps can approach each other to clamp the film.

[0012] As an improvement to the above solution, the film-tearing lifting mechanism includes a film-tearing lifting drive, a film-tearing lifting screw connected to the film-tearing lifting drive, and a film-tearing lifting seat connected to the film-tearing lifting screw. The film-tearing mechanism is mounted on the film-tearing lifting seat, and the film-tearing lifting drive can drive the film-tearing mechanism to move up and down through the film-tearing lifting seat.

The film-tearing mechanism is disposed within the film-tearing bearing, and the outer side of the film-tearing mechanism is pulsatorically connected to the film-tearing transmission component. The film-tearing rotation drive component can drive the film-tearing mechanism to rotate relative to the film-tearing lifting seat.

[0015] Implementing this utility model has the following beneficial effects:

[0016] The present invention relates to a film-tearing device for an automatic film removal equipment, comprising a film-tearing base, a film-tearing lifting mechanism disposed on the film-tearing base, a film-tearing rotating mechanism pulsatingly connected to the film-tearing lifting mechanism, and a film-tearing mechanism comprising the film-tearing clamp pulsatingly connected to the film-tearing rotating mechanism. The film-tearing lifting mechanism is used to drive the film-tearing mechanism to lift and lower, and the film-tearing rotating mechanism is used to drive the film-tearing clamp to rotate. The film-tearing lifting mechanism drives the film-tearing mechanism to move in a direction perpendicular to the board surface, which can adapt to the film removal needs of boards with different thicknesses. It avoids the deviation of the contact position between the film-tearing fixture and the film due to the difference in board thickness, thereby achieving basic adaptability to film-tearing conditions for boards with different thicknesses. The film-tearing rotation mechanism is connected to the film-tearing fixture and drives the film-tearing fixture to rotate, which can change the clamping direction of the film-tearing fixture. Then, the film-tearing angle can be adjusted according to the contour and bonding angle of the irregular film. There is no need to manually disassemble and adjust the installation angle of the film-tearing fixture, nor to adjust the board angle. This avoids film breakage and residue caused by uneven film force during the film-tearing process, and reduces the time spent on manual intervention. This achieves adaptable film-tearing for irregular films, improves the continuous operation efficiency of automatic film removal equipment, ensures uniform film-tearing accuracy, meets the industrial production requirements of large-scale, high-precision board film removal, and adapts to the automation and standardization production needs of modern board processing.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that any use of terms such as "up," "down," "left," "right," "front," "back," "inner," and "outer" in this document is based solely on the accompanying drawings and is not intended to limit the scope of this utility model.

[0022] See Figure 1 and Figure 2This utility model discloses a film-tearing device for an automatic film removal equipment, including a film-tearing base 1, a film-tearing lifting mechanism 2 disposed on the film-tearing base 1, a film-tearing rotating mechanism 3 driven by the film-tearing lifting mechanism 2, and a film-tearing mechanism 4 driven by the film-tearing rotating mechanism 3. The film-tearing lifting mechanism 2 drives the film-tearing mechanism 4 to move up and down. The film-tearing lifting mechanism 2 drives the film-tearing rotating mechanism 3 and the film-tearing mechanism 4 connected to it to move synchronously in a direction perpendicular to the surface of the board through a transmission structure. When dealing with boards of different thicknesses, the film-tearing lifting mechanism 2 can adjust the height of the film-tearing mechanism 4 according to the thickness of the board, so that the film-tearing clamp 41 in the film-tearing mechanism 4 can accurately contact the film on the surface of the board, avoiding the offset of the contact position between the film-tearing clamp 41 and the film due to the difference in board thickness, thereby ensuring the accuracy of the initial film-tearing position.

[0023] The film-tearing mechanism 4 includes a film-tearing clamp 41. The film-tearing rotation mechanism 3 is tractively connected to the film-tearing clamp 41. The film-tearing rotation mechanism 3 can drive the film-tearing clamp 41 to rotate, thereby changing the clamping direction of the film-tearing clamp 41. The rotational action of the film-tearing rotation mechanism 3 can be directly transmitted to the film-tearing clamp 41, causing the film-tearing clamp 41 to rotate around the transmission shaft, thereby changing the clamping direction of the film-tearing clamp 41. This process does not require manual disassembly or adjustment of the installation angle of the film-tearing clamp 41, nor does it require adjustment of the angle of the board itself. When encountering irregularly shaped films with arc-shaped, zigzag-shaped edges or films that are not perpendicular to the board surface, the film-tearing rotation mechanism 3 can drive the film-tearing clamp 41 to rotate to a suitable clamping direction in real time according to the contour and clamping angle of the irregularly shaped film. This allows the film-tearing clamp 41 to clamp and tear the film at an angle that is almost parallel to the extension direction of each part of the film, avoiding the problem of uneven film force caused by the fixed clamping direction in the prior art, thereby reducing the possibility of film breakage and residue.

[0024] The beneficial effects of this utility model embodiment are as follows:

[0025] This utility model embodiment of the film-tearing device for automatic film removal equipment includes a film-tearing base 1, a film-tearing lifting mechanism 2 disposed on the film-tearing base 1, a film-tearing rotating mechanism 3 drivenly connected to the film-tearing lifting mechanism 2, and a film-tearing mechanism 4 drivenly connected to the film-tearing rotating mechanism 3 and including the film-tearing clamp 41. The film-tearing lifting mechanism 2 is used to drive the film-tearing mechanism 4 to rise and fall, and the film-tearing rotating mechanism 3 is used to drive the film-tearing clamp 41 to rotate. The film-tearing lifting mechanism 2 drives the film-tearing mechanism 4 to move in a direction perpendicular to the board surface, which can adapt to the film removal needs of boards with different thicknesses. It avoids the deviation of the contact position between the film-tearing clamp 41 and the film due to the difference in board thickness, thereby achieving basic adaptation of film-tearing conditions for boards with different thicknesses. The film-tearing rotating mechanism 3 is connected to the film-tearing clamp 41 and drives the film-tearing clamp 41 to rotate, which can change the clamping direction of the film-tearing clamp 41. Then, the film-tearing angle can be adjusted according to the contour and bonding angle of the irregular film. There is no need to manually disassemble and adjust the installation angle of the film-tearing clamp 41, nor is there a need to adjust the board angle. This avoids film breakage and residue caused by uneven film force during the film-tearing process, and reduces the time spent on manual intervention. This achieves adaptable film-tearing for irregular films, improves the continuous operation efficiency of automatic film removal equipment, ensures uniform film-tearing accuracy, meets the industrial production requirements of large-scale, high-precision board film removal, and adapts to the automation and standardization production needs of modern board processing.

[0026] See Figure 2 The film-tearing mechanism 4 further includes a film-tearing rotating sleeve 42 and a film-tearing movable rod 43. The film-tearing rotating sleeve 42 is sleeved around and connected to the film-tearing movable rod 43. The film-tearing rotating sleeve 42 can drive the film-tearing movable rod 43 to rotate. The film-tearing rotating mechanism 3 is drivenly connected to the outer side of the film-tearing rotating sleeve 42. The bottom of the film-tearing movable rod 43 is connected to the film-tearing clamp 41. The rotational power output by the film-tearing rotating mechanism 3 can act on the film-tearing rotating sleeve 42, and through the connection between the film-tearing rotating sleeve 42 and the film-tearing movable rod 43, the rotational action is synchronously transmitted to the film-tearing movable rod 43, ultimately realizing the transmission of the action of the film-tearing rotating mechanism 3 driving the film-tearing clamp 41 to rotate.

[0027] The film-tearing mechanism 4 further includes a film-tearing connecting sleeve 44, the bottom of which is fitted onto the top of the film-tearing rotating sleeve 42. A horizontally arranged film-tearing partition 441 is provided inside the film-tearing connecting sleeve 44, dividing the internal space of the film-tearing connecting sleeve 44 into two parts. The film-tearing partition 441 and the bottom of the film-tearing rotating sleeve 42 form a film-tearing floating cavity 442. The film-tearing mechanism 4 also includes a film-tearing floating elastic element 45, the film-tearing floating cavity 442 providing space for the film-tearing floating elastic element 45 to extend and retract. The top of the film-tearing floating elastic element 45 abuts against the film-tearing partition 441, and the bottom of the film-tearing floating elastic element 45 abuts against the top of the film-tearing rotating sleeve 42 or the film-tearing movable rod 43. When the film-tearing clamp 41 approaches and contacts the board under the drive of the film-tearing lifting mechanism 2, the board generates an upward reaction force on the film-tearing clamp 41. This reaction force is transmitted to the film-tearing floating elastic element 45 through the film-tearing movable rod 43 (or the film-tearing rotating sleeve 42), causing the film-tearing floating elastic element 45 to be compressed and undergo elastic deformation, transforming rigid contact into elastic contact. This absorbs the impact force at the moment of contact, ensuring that the pressure of the film-tearing clamp 41 remains within a safe range when it contacts the board. This does not affect the clamping force of the film-tearing clamp 41 on the film, and effectively protects the surface of the board from damage, further adapting to the production requirements of high-precision board film removal.

[0028] See Figure 1 and Figure 2The film-tearing device for the automatic film removal equipment further includes a film-tearing pipeline processing mechanism 5. The film-tearing pipeline processing mechanism 5 includes a film-tearing slip ring 51 and a film-tearing air pipe connector 52. The film-tearing slip ring 51 is located at the top of the film-tearing connecting sleeve 44 and is relatively stationary with the film-tearing connecting sleeve 44 via a fixed connection. The film-tearing partition 441 and the upper part of the film-tearing connecting sleeve 44 form a film-tearing air pipe receiving cavity 443. This cavity provides an independent installation and protection space for the film-tearing air pipe connector 52. The film-tearing air pipe connector 52 is fixed to the bottom of the film-tearing slip ring 51 and located within the film-tearing air pipe receiving cavity 443. One end of the film-tearing air pipe connector 52 is connected to an external air pipe through the film-tearing slip ring 51, and the other end is connected to an internal film-tearing air pipe 53. The internal film-tearing air pipe 53 provides pneumatic power to the film-tearing clamp 41. The tear-off air tube connector 52 serves as a transitional connection between the external air tube and the inner tear-off air tube 53. On one hand, it can be fixedly connected to the external air tube, preventing it from being affected by the rotation of the tear-off clamp 41. On the other hand, it can connect to the inner tear-off air tube 53, providing pneumatic power to the tear-off clamp 41. The inner tear-off air tube 53 is connected to the tear-off clamp 41. When the tear-off clamp 41 rotates, the inner tear-off air tube 53 will rotate, and the tear-off air tube receiving cavity 443 provides space for the rotational movement of the inner tear-off air tube 53. Without a similar film-tearing pipeline processing mechanism 5, the air pipe supplying air to the film-tearing clamp 41 is prone to entanglement and pulling as the clamp rotates, leading to air pipe damage and leakage or movement stagnation, affecting the stable supply of pneumatic power. However, in this embodiment of the utility model, the film-tearing slip ring 51 cooperates with the fixed film-tearing air pipe connector 52, combined with the movable film-tearing inner air pipe 53, which not only ensures the stable connection between the external and internal air paths, but also avoids the problem of pipeline entanglement. This ensures that the pneumatic power supply of the film-tearing clamp 41 is continuous and stable during the adjustment of the clamping direction or lifting and lowering process, without affecting the continuity and reliability of the film-tearing action.

[0029] The tear-off partition 441 has a tear-off communication hole 444 in the middle, and the tear-off movable rod 43 has a tear-off inner rod hole 431 inside. The tear-off inner rod hole 431 and the tear-off communication hole 444 are coaxially arranged, and the coaxial design provides a precise channel guide for the insertion of the tear-off inner air tube 53. The tear-off air tube receiving cavity 443 and the tear-off floating cavity 442 are connected through the tear-off communication hole 444, so that the two independent cavities form an internally connected space, providing a path for the air passage to extend from the tear-off air tube receiving cavity 443 to the tear-off floating cavity 442. The tear-off inner air tube 53 passes downward through the tear-off communication hole 444 and extends into the tear-off inner rod hole 431 to communicate with the tear-off clamp 41. The tear-off inner air tube 53 is completely hidden in the internal space of the tear-off connecting sleeve 44 and the tear-off movable rod 43, avoiding the exposure of the pipeline. The tear film connecting hole 444 and the tear film inner rod hole 431 are coaxial, guiding the tear film inner air tube 53 to extend along a fixed path, which neither occupies external space nor interferes with the extension and retraction movement of the tear film floating elastic element 45.

[0030] See Figure 3The tear-off partition 441 has an integrally formed or fixedly provided lower tear-off protruding ring 445 in its middle part. The lower tear-off protruding ring 445 protrudes downward, and the tear-off connecting hole 444 is disposed inside the lower tear-off protruding ring 445. The position of the tear-off connecting hole 444 is defined by the lower tear-off protruding ring 445 surrounding it. Correspondingly, the top of the tear-off movable rod 43 is provided with an upper tear-off protruding ring 432. The upper tear-off protruding ring 432 protrudes upward, forming a protruding structure corresponding to the position of the lower tear-off protruding ring 445. The upper part of the tear-off inner rod hole 431 is disposed inside the upper tear-off protruding ring 432. The upper part of the tear-off floating elastic member 45 is sleeved outside the lower tear-off protruding ring 445, and the lower part of the tear-off floating elastic member 45 is sleeved outside the upper tear-off protruding ring 432. The outer peripheral walls of the two protruding rings form a radial limit on the tear-off floating elastic member 45. The tear-off inner air tube 53 passes through the hollow portion of the tear-off floating elastic member 45. It extends sequentially through the tear-off connecting hole 444 in the lower tear-off ring 445 and the tear-off inner rod hole 431 in the upper tear-off ring 432 to the tear-off clamp 41. Here, the upper tear-off ring 432 and the lower tear-off ring 445 form a "vertically aligned" limiting structure, and their inner walls can limit the radial position of the tear-off inner air tube 53. When the film-tearing clamp 41 rotates with the film-tearing rotating mechanism 3 or moves with the film-tearing floating elastic element 45, the film-tearing inner air tube 53 is always constrained in the axial region of the two convex rings. This prevents the film-tearing inner air tube 53 from rubbing against the hole wall of the film-tearing connecting hole 444 and the hole wall of the film-tearing inner rod hole 431 due to shaking. Long-term friction with the hole wall will cause wear on the outer wall of the air tube, reduce the sealing performance, and even cause air leakage in the air passage. In this embodiment, the double limiting of the two convex rings ensures that the film-tearing inner air tube 53 always extends along the axial path and does not come into contact with the hole wall for wear. At the same time, the guidance of the film-tearing floating elastic element 45 ensures that its buffering function is stably performed.

[0031] See Figure 4The film-tearing clamp 41 includes two film-tearing clamping blocks 411 symmetrically arranged at the bottom of the film-tearing clamp 41. The two film-tearing clamping blocks 411 can move closer or further apart under the action of the driving structure. When the film needs to be clamped, the two film-tearing clamping blocks 411 move closer to each other, forming a clamping force through contact on opposite sides. After film tearing is completed, the two film-tearing clamping blocks 411 move further apart, releasing the clamping of the residual film for the next film-tearing operation. Each film-tearing clamping block 411 includes a connecting section 4111 and an inclined section 4112. The connecting section 4111 extends downwards, and the inclined section 4112 is connected to the connecting section 4111 and extends downwards at an angle. Opposite sides of the inclined sections 4112 of the two film-tearing clamping blocks 411 can move closer together to clamp the film. When the two film-tearing clamping blocks 411 approach each other, the opposite sides of the inclined sections 4112 on both sides first contact the edge of the film. As the clamping action progresses, the inclination angle of the inclined sections 4112 allows the clamping surface to fit against the edge of the film.

[0032] See Figure 1 The film-tearing lifting mechanism 2 includes a film-tearing lifting drive 21, a film-tearing lifting screw 22 connected to the film-tearing lifting drive 21, and a film-tearing lifting seat 23 connected to the film-tearing lifting screw 22. The film-tearing mechanism 4 is mounted on the film-tearing lifting seat 23. The film-tearing lifting drive 21 can drive the film-tearing mechanism 4 to move up and down through the film-tearing lifting seat 23. The rotational power output by the film-tearing lifting drive 21 is converted into the circular motion of the film-tearing lifting screw 22, and then converted into the linear motion of the film-tearing lifting seat 23 along the screw axis through threaded engagement. Since the film-tearing mechanism 4 is directly mounted on the film-tearing lifting seat 23, the film-tearing lifting drive 21 can drive the entire film-tearing mechanism 4 to move up and down through the film-tearing lifting seat 23.

[0033] The film-tearing rotation mechanism 3 includes a film-tearing connecting platform 31 fixed to the film-tearing lifting seat 23, a film-tearing connecting block 32 fixed to the film-tearing connecting platform 31, a film-tearing rotation drive 33 fixed to the film-tearing connecting platform 31, a film-tearing transmission component 34 that is pulsatorically connected to the movable end of the film-tearing rotation drive 33, and a film-tearing bearing (not shown in the figure) disposed in the film-tearing lifting seat 23. The film-tearing mechanism 4 is disposed in the film-tearing bearing, and the outer side of the film-tearing mechanism 4 is pulsatorically connected to the film-tearing transmission component 34. The film-tearing rotary drive 33 is connected to drive the film-tearing mechanism 4 to rotate relative to the film-tearing lifting seat 23. The film-tearing rotary drive 33 drives the film-tearing transmission component 34 to rotate. Through the transmission cooperation between the film-tearing transmission component 34 and the outer side of the film-tearing mechanism 4, the film-tearing mechanism 4 is driven to rotate around the axis of the film-tearing bearing. Finally, the film-tearing rotary drive 33 drives the film-tearing mechanism 4 to rotate stably relative to the film-tearing lifting seat 23, thereby changing the clamping direction of the film-tearing clamp 41. Furthermore, one end of the film-tearing connecting block 32 is fixedly connected to the film-tearing slip ring 51. The film-tearing slip ring 51 is relatively fixed to the film-tearing lifting seat 23 and the film-tearing connecting platform 31 through the film-tearing connecting block 32, ensuring that the film-tearing slip ring 51 always remains stationary. When the film-tearing mechanism 4 rotates with the rotation action, the fixed film-tearing slip ring 51 can prevent the film-tearing air pipe connector 52 connected to it from rotating, thereby preventing the film-tearing internal air pipe 53 from getting tangled, ensuring a stable air supply, and achieving coordinated adaptation.

[0034] This utility model embodiment also discloses an automatic film removal device, including the film-tearing device for automatic film removal as described above. The film-tearing device for automatic film removal includes a film-tearing base 1, a film-tearing lifting mechanism 2 disposed on the film-tearing base 1, a film-tearing rotating mechanism 3 drivenly connected to the film-tearing lifting mechanism 2, and a film-tearing mechanism 4 drivenly connected to the film-tearing rotating mechanism 3 and including the film-tearing clamp 41. The film-tearing lifting mechanism 2 is used to drive the film-tearing mechanism 4 to rise and fall, and the film-tearing rotating mechanism 3 is used to drive the film-tearing clamp 41 to rotate. The film-tearing lifting mechanism 2 drives the film-tearing mechanism 4 to move in a direction perpendicular to the board surface, which can adapt to the film removal needs of boards with different thicknesses. It avoids the deviation of the contact position between the film-tearing clamp 41 and the film due to the difference in board thickness, thereby achieving basic adaptation of film-tearing conditions for boards with different thicknesses. The film-tearing rotating mechanism 3 is connected to the film-tearing clamp 41 and drives the film-tearing clamp 41 to rotate, which can change the clamping direction of the film-tearing clamp 41. Then, the film-tearing angle can be adjusted according to the contour and bonding angle of the irregular film. There is no need to manually disassemble and adjust the installation angle of the film-tearing clamp 41, nor is there a need to adjust the board angle. This avoids film breakage and residue caused by uneven film force during the film-tearing process, and reduces the time spent on manual intervention. This achieves adaptable film-tearing for irregular films, improves the continuous operation efficiency of automatic film removal equipment, ensures uniform film-tearing accuracy, meets the industrial production requirements of large-scale, high-precision board film removal, and adapts to the automation and standardization production needs of modern board processing.

[0035] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
