In order to make the present application clear, elements not related to the description are omitted from the details of this specification.

[0069] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0070] The present application discloses a film tearing device including a bracket, a lifting assembly, a translation assembly, a clamping assembly and a trajectory adjustment mechanism. The bracket is provided with a platform, and the platform is used to contact the product. The lifting assembly is slidably arranged on the bracket, and the lifting assembly can slide up and down along a first direction relative to the bracket. The translation assembly is arranged on the lifting assembly and can slide along a second direction relative to the lifting assembly. The clamping assembly is fixed on the translation assembly and is used to clamp the film on the product. The trajectory adjustment mechanism is arranged on the bracket and contacts the translation assembly, and the trajectory adjustment mechanism is used to control the sliding trajectory of the translation assembly.

[0071] The film tearing device of the above embodiment drives the translation assembly and the clamping assembly to move downward through the lifting assembly, and at the same time drives the translation assembly and the clamping assembly to move horizontally relative to the lifting assembly through the trajectory adjustment mechanism, thereby achieving the effect of automatic film tearing.

[0072] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0073] The first direction, the second direction and the third direction are perpendicular to each other, the first direction is a vertically upward direction, and the second direction and the third direction are both horizontal directions. The first direction is a direction parallel to the X-axis, the first direction is toward the positive direction of the X-axis, and the opposite direction of the first direction is toward the negative direction of the X-axis. The second direction is a direction parallel to the Y-axis, the second direction is toward the positive direction of the Y-axis, and the opposite direction of the second direction is toward the negative direction of the Y-axis. The third direction is a direction parallel to the Z-axis, the third direction is toward the positive direction of the Z-axis, and the opposite direction of the third direction is toward the negative direction of the Z-axis.

[0074] See also Figure 1 , which is a schematic diagram of a manual film tearing method of a film 30, the film 30 is located on the bottom surface of the product 20, and the film 30 has a head end 31 and a tail end 32 opposite to each other. In the process of manual film tearing, the head end 31 of the film 30 is generally moved away from the product 20 along the positive direction of the X-axis (i.e., a direction perpendicular to the surface of the product 20), and at the same time, the film 30 is moved along the head end 31 toward the direction close to the tail end 32 (i.e., a horizontal direction), so as to tear the film 30 from the product 20. Figure 1 The S line in FIG. 3 is the moving track of the head end 31 .

[0075] See also Figure 2 , which is a structural schematic diagram of a film tearing device 10 provided in an embodiment of the present application, and the film tearing device 10 includes a bracket 11, a lifting component 13, a translation component 101, a trajectory adjustment mechanism 14 and a clamping component 12. The bracket 11 is provided with a platform 111, and the platform 111 is used to contact the bottom surface of the product 20 that is not adhered with the film 30. The lifting component 13 is slidably arranged on the bracket 11, and the lifting component 13 can slide up and down along the X-axis direction relative to the bracket 11. The translation component 101 is arranged on the lifting component 13 and can slide relatively along the Y-axis direction relative to the lifting component 13. The clamping component 12 is fixed on the translation component 101. The trajectory adjustment mechanism 14 is arranged on the bracket 11 and contacts the translation component 101, and is used to control the sliding trajectory of the translation component 101. The clamping component 12 is used to clamp the head end 31 of the film 30 on the bottom surface of the product 20.

[0076] When tearing the film, the product 20 with the film 30 is placed on the platform 111, the clamping assembly 12 clamps the head end 31 of the film 30, and the lifting assembly 13 moves downward along the negative direction of the X-axis, while driving the translation assembly 101 and the clamping assembly 12 to move downward. Since the trajectory adjustment mechanism 14 is in contact with the translation assembly 101, the trajectory adjustment mechanism 14 controls the movement trajectory of the translation assembly 101 during the downward movement of the translation assembly 101, so that the translation assembly 101 moves toward the end 32 of the film 30 while sliding downward, and then during the downward movement of the clamping assembly 12, the head end 31 of the clamped film 30 moves toward the direction close to the end 32, so as to facilitate the separation of the film 30 from the product 20. At this time, the head end 31 of the film 30 is located at Figure 3 The clamping assembly 12 moves along the negative direction of the X-axis and the negative direction of the Y-axis to tear off the film 30, which simulates the manual film tearing (see Figure 1 ) in order to increase the angle between the film 30 and the product 20, thereby facilitating the separation of the film 30 from the product 20, helping to reduce the risk of tearing of the film 30, and thereby avoiding the situation where part of the film 30 remains on the product 20 after tearing.

[0077] See also Figure 3 , Figure 3 A schematic diagram showing a manual film tearing method and a quick film tearing method. Further, after the clamping assembly 12 moves a certain distance along the negative direction of the Y axis, the trajectory adjustment mechanism 14 causes the translation assembly 101 and the clamping assembly 12 to move relative to the lifting assembly 13 along the positive direction of the Y axis, that is, the clamping assembly 12 causes the head end 31 of the film 30 to move in a direction away from the end 32, so as to achieve the purpose of straightening the film 30. The clamping assembly 12 drives the head end 31 to continue to move in the positive direction of the Y axis and the negative direction of the X axis until the film 30 is completely torn off. At this time, the head end 31 of the film 30 is located at Figure 3 The position of point C on line b in the figure, line b is the horizontal height line, and S1 is the Figure 1 S1 is the moving trajectory of the head end 31 of the manual film tearing method, and S2 is the moving trajectory of the head end 31 of the fast film tearing method.

[0078] Please continue reading Figure 3 The position of line b is higher than that of line a. Therefore, the position difference between line b and line a is the distance reduced when the film tearing device 10 is used to tear the film. The downward movement of the clamping assembly 12 saves the time for tearing the film 30 and improves the film tearing efficiency of the film tearing device 10.

[0079] In addition, compared with the manual film tearing method, the quick film tearing method reduces the distance that the lifting component 13 drives the clamping component 12 to move downward (such as Figure 3Therefore, when it is necessary to tear off the film 30 on the next product 20, the distance that the lifting component 13 drives the clamping component 12 to move upward and reset is shortened. Under the premise that the moving speed of the lifting component 13 remains unchanged, the purpose of shortening the film tearing interval is achieved, thereby further improving the film tearing efficiency of the film tearing device 10.

[0080] In some embodiments, see Figure 4 and Figure 5 The trajectory adjustment mechanism 14 includes an elastic member and a trajectory adjustment member 141, and the elastic member is a tension spring 142. One end of the tension spring 142 is connected to the clamping assembly 12, and the other end is connected to the lifting assembly 13. A trajectory adjustment profile 1410 is provided on the side of the trajectory adjustment member 141 facing the negative direction of the Y axis. The trajectory adjustment profile 1410 includes a first working surface 1411 and a second working surface 1412, the first working surface 1411 gradually tilts from the upper right to the lower left, the second working surface 1412 gradually tilts from the upper left to the lower right, and the part of the first working surface 1411 close to the lower left is connected to the part of the second working surface 1412 close to the upper left, and the connection between the first working surface 1411 and the second working surface 1412 protrudes outward, and the tension spring 142 enables the translation assembly 101 to maintain contact with the trajectory adjustment profile 1410 during the movement.

[0081] When the clamping assembly 12 moves downward to tear the film, since the first working surface 1411 is an inclined surface, during the downward movement of the translation assembly 101, it simultaneously translates and slides along the negative direction of the Y axis, and during the translation and sliding process, the tension spring 142 is elastically deformed, and the translation assembly 101 translates and slides to the connection between the first working surface 1411 and the second working surface 1412. When the translation assembly 101 passes over the connection, the translation assembly 101 continues to move downward along the second working surface 1412, and since the second working surface 1412 is an inclined surface, during the downward movement of the translation assembly 101, it simultaneously translates and slides along the positive direction of the Y axis, and during the translation and sliding process, the tension spring 142 is elastically restored.

[0082] In other embodiments, the trajectory adjustment mechanism 14 is a cylinder, so that the clamping assembly 12 can move along the negative direction of the Y axis and the negative direction of the X axis under the joint action of the lifting assembly 13 and the cylinder. Compared with the trajectory adjustment mechanism 14 being a cylinder, the trajectory adjustment mechanism 14 adopts a cam structure to ensure that the clamping assembly 12 can move stably and quickly in the positive direction of the Y axis.

[0083] In other embodiments, see Figure 6, the trajectory adjustment mechanism 14 includes an elastic member and a trajectory adjustment member 141, and the elastic member is a compression spring. One end of the compression spring is connected to the clamping assembly 12, and the other end is connected to the lifting assembly 13. A trajectory adjustment profile 1410 is provided on the side of the trajectory adjustment member 141 facing the positive direction of the Y axis, and the compression spring enables the translation assembly 101 to maintain a state of contact with the trajectory adjustment profile 1410 during the movement. The trajectory adjustment profile 1410 includes a third working surface 1413 and a fourth working surface 1414, and the fourth working surface 1414 is connected to one end of the third working surface 1413, and the third working surface 1413 is gradually inclined from the upper right to the lower left, and the fourth working surface 1414 is gradually inclined from the upper left to the lower right. The part of the third working surface 1413 close to the lower left is connected to the part of the fourth working surface 1414 close to the upper left, and the connection between the third working surface 1413 and the fourth working surface 1414 is concave inward.

[0084] When the clamping assembly 12 moves downward to tear the film, since the third working surface 1413 is an inclined surface, during the downward movement of the translation assembly 101, it also slides in translation along the negative direction of the Y axis, and during the translation and sliding process, the compression spring is changed from compression to recovery, and the translation assembly 101 slides in translation to the connection between the third working surface 1413 and the fourth working surface 1414. When the translation assembly 101 passes the connection, the translation assembly 101 continues to move downward along the fourth working surface 1414, and since the fourth working surface 1414 is an inclined surface, during the downward movement of the translation assembly 101, it also slides in translation along the positive direction of the Y axis, and during the translation and sliding process, the compression spring is compressed.

[0085] In some embodiments, see Figure 4 The translation assembly 101 includes a slider 1011 and a slide rail 1012. The slide rail 1012 is disposed on the lifting assembly 13. The slider 1011 is slidably connected to the slide rail 1012. The clamping assembly 12 includes a clamping driver 121 and two clamping jaws 122. The clamping driver 121 is connected to the slider 1011 and the two clamping jaws 122, respectively. The clamping driver 121 drives the two clamping jaws 122 to move closer or open, thereby achieving the effect of the two clamping jaws 122 clamping or releasing the film 30.

[0086] In some embodiments, the clamping assembly 12 is a clamping jaw cylinder.

[0087] In some embodiments, the two clamping jaws 122 are disposed one above the other so that the two clamping jaws 122 act on the top surface and the bottom surface of the film 30 respectively.

[0088] In some embodiments, see Figure 4The top and bottom of the clamping jaw 122 are both provided with inclined surfaces 1221, and the inclined surfaces 1221 are symmetrically arranged up and down so that the clamping jaw 122 can avoid the product 20 and the storage container 151 respectively.

[0089] In some embodiments, the two clamping jaws 122 may also be arranged in parallel in the positive direction of the Z axis, and both clamping jaws 122 are provided with inclined surfaces 1221 .

[0090] In some embodiments, the translation assembly 101 also includes a roller 1013 rotatably disposed on the slider 1011, and the roller 1013 contacts the track adjustment profile 1410 of the track adjustment member 141 so that the roller 1013 rolls in contact with the track adjustment profile 1410, thereby reducing the friction resistance between the translation assembly 101 and the track adjustment member 141.

[0091] In some embodiments, see Figure 2 The film tearing device 10 further includes a storage assembly 15, which includes a storage container 151. The top of the storage container 151 is provided with an adsorption chamber 150, which is connected to an external vacuum device. A negative pressure is formed in the adsorption chamber 150 under the action of the vacuum device. When the clamping assembly 12 tears off the film 30 of the product 20, the storage container 151 adsorbs the film 30 into the adsorption chamber 150 to store the film 30.

[0092] In some embodiments, the storage component 15 also includes a vacuum pipe 152, which is respectively connected to the adsorption chamber 150 and an external vacuum device. The film 30 located in the adsorption chamber 150 is transferred to the outside of the storage container 151 through the vacuum pipe 152 under the action of negative pressure to empty the adsorption chamber 150, thereby facilitating the storage container 151 to continue to store the film 30.

[0093] In some embodiments, the storage containers 151 are respectively located on both sides of the bracket 11 in the Z-axis direction, and the clamping components 12 are also respectively located on both sides of the bracket 11 in the Z-axis direction.

[0094] In some embodiments, when there are two films 30 on the product 20 , a receiving assembly 15 and a clamping assembly 12 are disposed vertically opposite to each other, so that a receiving assembly 15 can accurately receive a film 30 torn off by a clamping assembly 12 .

[0095] In some embodiments, see Figure 7The lifting assembly 13 includes a lifting driver 132 and a lifting member 133. The lifting member 133 is connected to the slider 1011 and the lifting driver 132 respectively. The slide rail 1012 is arranged on the top of the lifting member 133. The lifting driver 132 drives the lifting member 133 to drive the slider 1011 to move back and forth in the positive direction and the negative direction of the X-axis, so that the slider 1011 drives the clamping driver 121 and the two clamping claws 122 to move along the positive direction of the X-axis or along the negative direction of the X-axis.

[0096] In some embodiments, the clamping driver 121 and the lifting driver 132 are both cylinders.

[0097] In some embodiments, the lifting assembly 13 further includes a guide rail 134 extending along the X-axis direction, and the guide rail 134 is located on the bracket 11. The lifting member 133 is slidably connected to the guide rail 134, and the lifting member 133 moves up and down relative to the guide rail 134.

[0098] In some embodiments, the platform 111 is disposed on top of the guide rail 134 .

[0099] In some embodiments, see Figure 2 and Figure 4 The film tearing device 10 further includes a position adjustment component 16 , which is disposed on the lifting member 133 . The position adjustment component 16 is used to adjust the relative position between the two clamping jaws 122 and the lifting member 133 .

[0100] In some embodiments, the position adjustment component 16 includes a slide cylinder 161, which is respectively connected to the slider 1011 and the lifting member 133. The slide cylinder 161 is configured to drive the slider 1011 to move. The relative position between the two clamps 122 and the slider 1011 is adjusted by the slide cylinder 161, thereby improving the accuracy of the position of the two clamps 122.

[0101] In other embodiments, the position adjustment assembly 16 also includes an adjusting bolt (not shown), which is threadedly connected to the lifting member 133, and one end of the adjusting bolt is telescopically movable in the positive direction of the Y-axis relative to the lifting member 133, and acts on the slider 1011, thereby causing the slider 1011 to move relative to the lifting member 133.

[0102] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the essential scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
