[0046] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0047] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0048] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used to describe the relative position relationship of components in the direction shown in the drawings or in the vertical, perpendicular or gravity direction.

[0049] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0050] The utility model firstly provides a film tearing device.

[0051] In one embodiment, referring to the attached Figure 1 To Attachment Figure 3 As shown, the film tearing device includes:

[0052] Mounting seat 110;

[0053] The film suction assembly 120 is disposed on the mounting seat 110 and includes a suction cup 121 arranged downward and a suction cup driving member 122 drivingly connected to the suction cup 121. The suction cup 121 moves vertically in the up-down direction under the driving of the suction cup driving member 122.

[0054] The film clamping assembly 130 is arranged on the mounting seat 110 and includes a clamping finger 131 and a clamping finger driving member 132 driven by the clamping finger 131. The clamping finger 131 moves under the drive of the clamping finger driving member 132 so that it can be pressed against the adsorption surface of the suction cup 121 or avoid the side of the suction cup 121.

[0055] It should be noted that the suction cup 121 is arranged downward, that is, the adsorption surface of the suction cup 121 is arranged horizontally and faces downward.

[0056] When the film tearing device of this embodiment is used to tear film, the suction cup 121 can be driven by the suction cup driving member 122 to move vertically downward to adsorb the edge of the protective film on the film to be torn off, and then move vertically upward to separate the edge of the protective film from the film to be torn off. Then, the clamping finger driving member 132 drives the clamping finger 131 to press against the adsorption surface of the suction cup 121 to clamp the separated part of the protective film and the film to be torn off together with the suction cup 121. At this time, the protective film and the film to be torn off can be completely separated by moving the mounting seat 110 upward to drive the film suction assembly 120 and the film clamping assembly 130 to move upward synchronously, so as to achieve the purpose of film tearing. That is to say, the film tearing device of this embodiment does not need to tear film by clamping the ear handle of the protective film extending out of the edge of the film to be torn off, and can tear film when the ear handle of the protective film extending out of the edge of the film to be torn off is short or the entire protective film is completely attached to the film to be torn off, and has good applicability.

[0057] In addition, the clamping fingers 131 can be driven by the clamping finger driving member 132 to avoid the side of the suction cup 121. This arrangement can effectively avoid the problem of interference between the clamping fingers 131 and the protective film when the suction cup 121 absorbs or discards the protective film.

[0058] It is understandable that the moving route of the clamping finger 131 driven by the clamping finger driving member 132 can be various, such as an inclined route, an arc route, a right-angle route, etc., or a combination of routes of various shapes. In actual application, the design selection is made according to the needs. In addition, the orientation of the clamping finger 131 when avoiding the side of the suction cup 121 can be arranged in a variety of ways. For example, it can be arranged upward (that is, the pressing surface of the clamping finger 131 is arranged horizontally and facing upward), so that the clamping finger 131 can be pressed against the adsorption surface of the suction cup 121 by translating the clamping finger 131. It can also be arranged vertically (that is, the pressing surface of the clamping finger 131 is arranged vertically), so that in the process of moving the clamping finger 131 to press against the adsorption surface of the suction cup 121, the clamping finger 131 needs to be rotated to be arranged upward.

[0059] In one embodiment, referring to the attached Figure 1 To Attachment Figure 3 As shown, the film clamping assembly 130 also includes:

[0060] The guide plate 133 is fixedly disposed on the mounting base 110 and is provided with a guide bar hole, wherein a first end of the guide bar hole in the length direction is disposed close to the suction cup 121, and a second end of the guide bar hole in the length direction is disposed away from the suction cup 121 and is located below the first end;

[0061] The guide member 134 has one end fixedly connected to the clamping finger 131 and the other end slidably or rollably disposed in the guide bar hole, so that the clamping finger 131 moves along the guide bar hole under the drive of the clamping finger driving member 132 .

[0062] It can be understood that the guide member 134 moves synchronously with the clamping finger 131. Therefore, under the limiting guiding action of the guide member 134, the clamping finger 131 moves along the guide strip hole, so that it can move between the clamping film position pressed against the adsorption surface of the suction cup 121 and the avoidance position avoided on the side of the suction cup 121. This arrangement allows the clamping finger 131 to move according to the set movement route under the drive of the clamping finger driving member 132. In other words, the movement route of the clamping finger 131 can be set by setting the shape of the guide strip hole. In this way, the reliability of the movement of the clamping finger 131 according to the set route can be ensured, so that the clamping finger 131 can accurately fit the adsorption surface of the suction cup 121 or avoid the suction cup 121.

[0063] In actual application, the first end and the second end of the guide strip hole can correspond to the clamping position where the clamping finger 131 is pressed against the adsorption surface of the suction cup 121 and the avoidance position where it avoids to the side of the suction cup 121, respectively. In other words, when the guide member 134 moves to the first end of the guide strip hole, the clamping finger 131 moves to the clamping position where it is pressed against the adsorption surface of the suction cup 121, and when the guide member 134 moves to the second end of the guide strip hole, the clamping finger 131 moves to the avoidance position where it avoids to the side of the suction cup 121.

[0064] In one embodiment, referring to the attached Figure 1 To Attachment Figure 3 As shown, the guide strip hole includes a straight section and an arc section which are smoothly connected in sequence from the second end to the first end, the straight section extends in the horizontal direction, and the arc section gradually extends upward at an inclination.

[0065] In this embodiment, the movement path of the clamping finger 131 can be made smoother, and in the process of the guide member 134 moving upward along the arc segment, the clamping finger 131 simultaneously moves upward along the arc path toward the adsorption surface of the suction cup 121. When the guide member 134 moves to the first end of the guide bar hole, the clamping finger 131 is just pressed against the adsorption surface of the suction cup 121. In this way, the problem of mutual wear caused by the clamping finger 131 and the suction cup 121 moving relative to each other after being fitted can be avoided.

[0066] In one embodiment, referring to the attached Figure 1 To Attachment Figure 3 As shown, the finger driver 132 is a slide cylinder whose slide can move horizontally. The cylinder body of the finger driver 132 is set on the mounting seat 110, and the fingers 131 are arranged upward and slidably set on the slide of the finger driver 132 in the up and down directions.

[0067] It should be noted that the slide cylinder is a device well known to those skilled in the art, and therefore, the specific structure and working principle of the slide cylinder are not described in detail. In addition, the clamping fingers 131 are arranged upward, that is, the pressing surfaces of the clamping fingers 131 are arranged horizontally and face upward.

[0068] In this embodiment, the gripping finger 131 can be moved along a preset route by the driving of the gripping finger driving member 132 and the guiding of the guiding member 134. Specifically, during the horizontal movement of the slide of the gripping finger driving member 132, when the guiding member 134 moves along the straight section of the guide bar hole, the gripping finger 131 can be fixed relative to the slide of the gripping finger driving member 132 and move in the horizontal direction driven by the slide; when the guiding member 134 moves along the arc section of the guide bar hole, the gripping finger 131 can slide up and down relative to the slide of the gripping finger driving member 132 and gradually move up or down along the arc route driven by the slide.

[0069] It can be understood that the fingers 131 can be moved along a preset route by the driving of the finger driving member 132 and the guiding of the guiding member 134 to press against or avoid the suction cup 121. The driving structure is relatively simple and compact, which effectively improves the compactness of the overall structure of the film tearing device.

[0070] In this embodiment, the clamping finger driving member 132 adopts a slide cylinder, and the clamping finger 131 is directly installed on the mounting base 110 through the slide cylinder. Such an arrangement effectively simplifies the mounting structure of the clamping finger 131 and improves the compactness of the film tearing device.

[0071] Specifically, a mounting plate 135 is fixedly provided on the slide platform of the finger-gripping driving member 132, a slide rail extending in the up-down direction is fixedly provided on the mounting plate 135, a slider is provided on the finger-gripping 131, and through the sliding cooperation between the slider and the slide rail, the finger-gripping 131 can be slidably provided on the slide platform of the finger-gripping driving member 132 in the up-down direction.

[0072] Of course, in some other embodiments, the finger-gripping driving component 132 can also be a driving component such as a telescopic cylinder, an electric push rod, etc. Specifically, the output end of the finger-gripping driving component 132 is drivingly connected to a sliding seat slidably connected to the mounting seat 110, and the finger 131 is slidably arranged on the sliding seat along the up and down directions. The finger-gripping driving component 132 drives the sliding seat to move horizontally to drive the finger 131 to move horizontally.

[0073] In one embodiment, referring to the attached Figure 1 To Attachment Figure 3 As shown, the guide member 134 is a cam follower, the rod end of the guide member 134 is fixedly connected to the clamping finger 131, and the rolling end of the guide member 134 is rollably disposed in the guide bar hole.

[0074] It should be noted that the cam follower is a device well known to those skilled in the art, and therefore, the specific structure and working principle of the cam follower will not be described in detail herein.

[0075] Of course, in some other embodiments, the guide member 134 can also be of other structural forms. For example, the guide member 134 includes a connecting rod and a slider rotatably connected to one end of the connecting rod, and the end of the connecting rod away from the slider is fixedly connected to the clamping finger 131, and the slider is slidably disposed in the guide bar hole.

[0076] In one embodiment, referring to the attached Figure 1 To Attachment Figure 3 As shown, the suction cup driving member 122 is a slide cylinder whose slide can move vertically in the up-down direction, the cylinder body of the suction cup driving member 122 is arranged on the mounting seat 110, and the suction cup 121 is arranged on the slide of the suction cup driving member 122. In this arrangement, the suction cup 121 can be driven to move vertically in the up-down direction by the slide of the suction cup driving member 122 moving vertically in the up-down direction.

[0077] In this embodiment, the suction cup driving member 122 adopts a slide cylinder, and the suction cup 121 is directly installed on the mounting base 110 through the slide cylinder. Such an arrangement effectively simplifies the mounting structure of the suction cup 121 and improves the compactness of the film tearing device.

[0078] Specifically, a film suction head protruding outward is fixedly provided on the slide of the suction cup driving member 122, and the suction cup 121 includes a suction cup body fixedly arranged on the film suction head and a vacuum generator connected to the suction cup body. The suction cup body forms negative pressure on the adsorption surface through the vacuum generator to adsorb the protective film.

[0079] Of course, in some other embodiments, the suction cup driving component 122 can also be a driving component such as a telescopic cylinder, an electric push rod, etc. Specifically, the output end of the suction cup driving component 122 is drivingly connected to a sliding seat slidably connected to the mounting seat 110, and the suction cup 121 is arranged on the sliding seat. The suction cup driving component 122 drives the sliding seat to move vertically in the up and down directions to drive the suction cup 121 to move vertically in the up and down directions.

[0080] In one embodiment, referring to the attached Figure 1 To Attachment Figure 3 As shown, the film tearing device 100 further includes a mounting frame 140 and a film tearing driving member 150 drivingly connected to the mounting seat 110 . The mounting seat 110 is disposed on the mounting frame 140 and is driven by the film tearing driving member 150 to tilt and move in the up and down directions.

[0081] With such arrangement, in actual application, the arrangement position of the mounting bracket 140 can be adjusted according to actual needs, so that the inclined direction of movement of the driving mounting seat 110 of the film-tearing driving member 150 is set at an angle to the film-tearing direction (i.e., the direction from the separated part to the unseparated part of the protective film and the film to be torn off). In this way, after the suction cup 121 and the clamping fingers 131 clamp the separated part of the protective film and the film to be torn off, the driving mounting seat 110 of the film-tearing driving member 150 moves upwardly and tilts, driving the suction cup 121 and the clamping fingers 131 to clamp the protective film and move upwardly and tilt simultaneously to gradually peel the protective film off the film to be torn off. Compared with the method of tearing the film by vertically pulling up in the prior art, the stretching amount of the protective film can be reduced, the protective film can be prevented from being broken and causing incomplete film tearing, and the bonding auxiliary materials under the protective film can be prevented from being lifted up due to excessive pulling force, thereby effectively improving the reliability and efficiency of film tearing. For ease of understanding, please refer to the attached Figure 4 As shown, during the film tearing process of the film tearing device, the film tearing part is located at the lower left of the film tearing device, the suction cup 121 moves downward to absorb the protective film and then rises, and then the clamping finger 131 moves to press against the adsorption surface of the suction cup 121 to clamp the protective film with the suction cup 121, and then the film tearing driving part 150 slowly retracts to the upper left, so as to fold the protective film to the upper left to tear the film.

[0082] In one embodiment, referring to the attached Figure 1 To Attachment Figure 3 As shown, the film tearing driving component 150 is a slide cylinder whose slide can be tilted and moved in the up and down directions. The cylinder body of the film tearing driving component 150 is set on the mounting frame 140, and the mounting seat 110 is set on the slide of the film tearing driving component 150.

[0083] In this embodiment, the film tearing drive 150 adopts a slide cylinder, and the mounting seat 110 is directly mounted on the mounting frame 140 through the slide cylinder. Such a configuration effectively simplifies the mounting structure of the mounting seat 110 and further improves the compactness of the film tearing device.

[0084] Of course, in some other embodiments, the film tearing drive 150 can also be a drive component such as a telescopic cylinder, an electric push rod, etc. Specifically, the output end of the film tearing drive 150 is driven and connected to a sliding seat slidably connected to the mounting frame 140, and the mounting seat 110 is set on the sliding seat. The film tearing drive 150 drives the mounting seat 110 to move by driving movement.

[0085] The utility model also provides a film tearing device.

[0086] In one embodiment, referring to the attached Figure 4 and attached Figure 5 As shown, the film tearing equipment includes:

[0087] The frame has a film tearing station and a material throwing station;

[0088] The mobile module 200 is arranged on the frame;

[0089] The above-mentioned film tearing device 100 is arranged on the moving module 200 , and moves between the film tearing station and the material throwing station under the drive of the moving module 200 .

[0090] In this embodiment, after the film tearing device 100 tears the film to be torn off at the film tearing station, it moves to the material throwing station together with the clamped protective film under the drive of the moving module 200, discards the protective film at the material throwing station, and then returns to the film tearing station to tear off the film, and repeats this process.

[0091] Specifically, the film tearing equipment may further include a conveying device, which is arranged on the frame and is used to convey the film to be torn to the film tearing station, so that the process of loading, film tearing and waste film collection can be integrated and automated.

[0092] In one embodiment, referring to the attached Figure 4 and attached Figure 5 As shown, the film tearing device also includes:

[0093] The waste collecting device 300 is arranged on the frame and located at the throwing station. The waste collecting device 300 is provided with a negative pressure chamber and a waste collecting port connected to the negative pressure chamber.

[0094] In this way, when the film tearing device 100 moves to the throwing station, the clamping finger 131 moves to avoid the side of the suction cup 121, and the suction cup 121 breaks the vacuum to remove the adsorption effect on the protective film. The protective film is separated from the suction cup 121 and is collected into the negative pressure chamber from the waste collection port under the suction force of the negative pressure chamber of the waste collection device 300. In this way, efficient collection of the protective film can be achieved.
