Technical Field

[0001] The utility model relates to the field of automated mechanical design, in particular to a film-tearing paper mechanism. Background Art

[0002] During the automated film tearing process, due to the unique structure of the product, the release film can only be removed from the bottom. During this process, the product is easily pulled off due to the unreasonable direction and distribution of the tearing force, resulting in a low product yield.

[0003] Currently, factories generally use manual film tearing and then placing the products into automated machines for subsequent production. This method requires a large amount of manpower, prolongs the production cycle, increases costs, and fails to meet the requirements of lean production.

[0004] Therefore, in order to improve product production efficiency, increase product yield, and reduce the use of labor, it is now urgent to design a film tearing paper mechanism. Utility Model Content

At this time, the upper step surface is horizontally aligned with the film tearing platform, and forms an avoidance with the movement of the positioning fixture. The serrated structure on the top surface of the upper step cooperates with the film tearing platform and clamps the release film; when the pushing chuck is in the releasing state, the lower step is pulled downward by the pen-shaped cylinder until the lower inclined surface of the bending structure collides with the film tearing platform to limit the position. At this time, the upper step part of the pushing chuck is higher than the upper surface of the film tearing platform, and the serrated structure on the top surface of the upper step is released from the cooperation with the film tearing platform to release the release film.

DETAILED DESCRIPTION

[0025] In order to make the purpose, principle and structure of the present invention more clear, it is further described below with reference to the accompanying drawings and specific embodiments.

[0026] See also Figures 1-11 The utility model provides a film-tearing paper mechanism, comprising:

[0027] A multi-axis manipulator 13 is provided with a positioning fixture 7 connected to the lower portion of the movable end of the manipulator. The positioning fixture 7 holds a product 10 at the lower side, and a release film 8 is adhered to the lower side of the product 10.

[0028] The film-tearing platform 12 is provided below the positioning fixture 7. The film-tearing platform 12 is divided into a film-tearing starting station 12-1 and a film-absorbing station 12-2. The manipulator 13 places the positioning fixture 7 at the film-tearing starting station 12-1 and drives the positioning fixture 7 to move along the film-tearing platform 12 toward the film-absorbing station 12-2.

[0029] The push chuck 2 is positioned on the film tearing platform 12, between the film tearing starting station 12-1 and the film suction station 12-2, and is positioned adjacent to the film tearing starting station 12-1. The push chuck 2 is rotatably connected to the film tearing platform 12 via a swivel pin 9. The push chuck 2 is a stepped mechanism, with the swivel pin 9 positioned at the angle between the upper step 2-1 and the step riser. The lower step extension of the stepped structure forms a curved structure 2-3, within which a through slot 11 is disposed. The top surface of the upper step 2-1 of the stepped structure is a serrated structure 2-2.

[0030] The pen-shaped cylinder 1 has one end fixedly connected to the film-tearing platform 12 and the other end movably connected to the through slot 11 on the bending structure 2-3. The pen-shaped cylinder 1 drives the chuck 2 to rotate.

[0031] When the push chuck 2 is in the clamping state, the pen-shaped cylinder 1 pushes the bending structure 2-3, causing the lower step of the stepped structure to lift upward. The upper step 2-1, now rotated, presses downward against the film tearing platform 12, continuing its movement until the upper inclined surface 2-4 of the bending structure 2-3 collides with the film tearing platform 12, halting its movement. The upper step surface 2-6 now forms a single plane with the upper surface of the film tearing platform 12, providing a clearance for the movement of the push chuck 2. The serrated structure 2-2 on the end surface of the upper step now mates with the film tearing platform 12, creating a gap that holds the release film 8.

[0032] When the push chuck 2 is in the released state, the pen-shaped cylinder 1 pulls the bending structure 2-3, causing the lower step of the step mechanism to be pushed and pulled downward. The upper step 2-1 is then lifted and raised above the film tearing platform 12 under the action of rotation. The upper step 2-1 moves in unison until the lower inclined surface 2-4 of the bending structure 2-3 collides with the film tearing platform 12 and stops. At this time, the upper step surface 2-6 is at an angle to the upper surface of the film tearing platform 12, and the upper step 2-1 is higher than the upper surface of the film tearing platform 12. The serrated structure 2-2 on the end surface of the upper step is released from the film tearing platform 12, thereby releasing the release film 8. The raised upper step 2-1 and the film tearing platform 12 form a clearance structure that can accommodate the release film 8.

[0033] The film suction station 12-2 is equipped with several suction heads 4 on the film tearing platform 12. A push cylinder 3 is set on the side of the film suction station 12-2. A material guide trough 5 and a waste collection box 6 are set on the other side of the film suction station 12-2 corresponding to the push cylinder 3. The material guide trough 5 is set at an angle, with the upper end engaging with the film tearing platform 12 and the lower end engaging with the waste collection box 6.

[0034] Preferably, a long non-sticky area as a tear handle 8 - 1 is provided on the side of the release film 8 close to the pushing clamp 2 .

[0035] The specific working principle is as follows:

[0036] First, the positioning fixture 7 grips the product 10 with the release film 8 underneath. Driven by the robot 13, the positioning fixture 7 is placed at the film-tearing starting station 12-1 of the film-tearing platform 12. At this point, the push chuck 2 is lifted by the pen-shaped cylinder 1, and the upper step 2-1 of the push chuck 2 is raised above the film-tearing platform 12, forming a clearance structure between the push chuck 2 and the film-tearing platform 12. At this point, at the positioning fixture 7 at the film-tearing starting station 12-1, the tearing finger 8-1 on one side of the release film 8 is exposed from the positioning fixture 7, and the exposed portion of the tearing finger 8-1 is obscured by the clearance structure formed by the push chuck 2 and the film-tearing platform 12.

[0037] Secondly, the release film 8 is clamped. At this time, the pen-shaped cylinder 1 is driven to push and pull the bending structure 2-3 upward until the upper inclined surface 2-4 collides with the film tearing platform 12 to a limit position. The pushing chuck 2 is rotated along the rotating shaft 9, and the upper step 2-1 is rotated downward and closed until the upper step surface 2-6 and the upper surface of the film tearing platform 12 form an integral plane. During this process, the tearing hand 8-1 located in the air-avoiding structure will be pressed and clamped by the pushing chuck 2 that rotates downward and closes, and when the pushing chuck 2 and the film tearing platform 12 are fully closed, the tearing hand 8-1 will be pressed and clamped by the serrated structure 2-2 at the upper end of the pushing chuck 2 in the gap where the serrated structure 2-2 and the film tearing platform 12 are released.

[0038] Then, the robot 13 drives the positioning fixture 7 to move along the film tearing platform 12 from the film tearing starting station 12-1 to the film absorbing station 12-2. Figure 9 、 Figure 10At this point, the tearing finger 8-1 at one end of the release film 8 is bent and clamped at a 90-degree angle (this embodiment is limited to this embodiment, and the specific implementation is not limited to a 90-degree angle). When the positioning fixture 7 moves toward the film suction station 12-2, the release film 8 is elastically bent, and the release film 8 is bent at an angle of nearly 180 degrees (this embodiment is limited to this embodiment, and the specific implementation is not limited to 180 degrees). It is then gradually peeled off along the side toward the film suction station 12-2. Because the positioning fixture 2 is moving horizontally on the film tearing platform 12 at this time, its tearing finger 8-1 is always clamped. Therefore, during the release film 8 peeling process, the separation point 8-2 of the release film 8 can always be bent at an angle of nearly 180 degrees and then separated. This peeling effect causes the force generated during peeling to be always concentrated on the separation point 8-2 of the release film 8, so that the resistance between the release film 8 and the product 10 can be fully broken. By concentrating the force on the separation point 8-2 of the release film 8, it is possible to avoid excessive force being transferred to the release film 8 at the non-peeling point at the rear end, thereby avoiding excessive force being transferred to the product 10, thereby avoiding the product 10 being torn off by the separation force during the film tearing process.

[0039] Then, the positioning fixture 7 gradually moves to above the film suction station 12-2, at which point the peeled release film 8 also falls onto the film suction station 12-2. The suction head 4 on the film suction station 12-2 generates a vacuum suction effect, stably adsorbing the peeled release film 8 to the film suction station 12-2. After the release film 8 is fully peeled, it detaches from the positioning fixture 7 and is completely adsorbed to the film suction station 12-2.

[0040] Finally, the positioning fixture 7 carries the film-tearing product 10 away from the film-tearing platform 12 and into the next station. At this time, the pen-shaped cylinder 1 pulls back the bending mechanism 2-3 downward, pushing the clamp 2 to rotate along the rotating pin 9, the upper step 2-1 is lifted, the serrated structure 2-2 and the film-tearing platform 12 are released, and the tearing hand 8-1 of the release film 8 is released. After the action is completed, the suction head 4 reduces the negative pressure or stops working, so that the release film 8 is naturally placed on the film suction station 12-2 without being adsorbed or clamped. Drive the pushing cylinder 3 to push out, pushing the release film 8 away from the film-tearing platform 12, and the released release film 8 is transferred into the waste collection box 6 along the guide trough 5.

[0041] The above description is only a specific implementation method of this utility model, but the protection scope of this utility model is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by this utility model, can make equivalent substitutions or changes based on the technical solutions and new concepts of this utility model, which should be covered by the protection scope of this utility model.
