Description

Technical Field

[0001] This application belongs to the field of machining, and in particular relates to a film-tearing claw module and a film-tearing device. Background Technology

[0002] In existing technologies, mechanical film-tearing devices rely on multiple fixed grippers working together. However, the distribution of gripping points is limited and cannot be adjusted, resulting in uneven stress distribution during the film-tearing process. The peeling force is concentrated on a single or a few gripping points. If the local adhesion force of the film is large, the film is easily pulled off from the gripping edge, which can easily cause the film to break and affect work efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a film-tearing claw module and film-tearing device that can solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A film-tearing claw module includes a frame, an intermediate film clamping assembly disposed on the frame, and a side film clamping assembly located beside the intermediate film clamping assembly. The film-tearing claw module also includes an auxiliary film clamping assembly connected to the frame and located beside the intermediate film clamping assembly and / or the side film clamping assembly.

[0005] Furthermore, the auxiliary clamping assembly includes two independently driven auxiliary clamping claws, which are symmetrically distributed on both sides of the intermediate clamping assembly.

[0006] Furthermore, an axial angle adjustment component is provided at the fixed end of the auxiliary clamping claw, and the auxiliary clamping assembly can rotate around the first axis by the axial angle adjustment component.

[0007] Furthermore, there are two side-clamping assemblies, which are symmetrically distributed on both sides of the middle clamping assembly.

[0008] Furthermore, the side clamping assembly is also connected to a slide drive, which drives the side clamping assembly to move relative to the frame along the second axis.

[0009] Furthermore, the fixed end of the side clamping membrane assembly is also provided with a two-axis angle adjustment component, and the side clamping membrane assembly can be rotated around the second axis by the two-axis angle adjustment component.

[0010] Furthermore, the intermediate clamping assembly and the side clamping assembly each include a clamping claw drive and a main clamping claw disposed at the output end of the clamping claw drive.

[0011] Furthermore, the main clamping claw is also provided with an embossed clamping part, the surface pattern of which is one of mesh, stripe or dot-like protrusions.

[0012] Furthermore, the orientation of the main clamping claw opening of the intermediate clamping assembly and the orientation of the main clamping claw opening of the side clamping assembly are both parallel to the second axis.

[0013] As one application, this application also provides a film-tearing device, which includes the aforementioned film-tearing claw module.

[0014] Compared with existing technologies, the advantages of this application are: by adding an auxiliary film clamping assembly, it can effectively avoid the problems of film breakage, deformation or tearing caused by stress concentration during the peeling process, which is suitable for reliable film peeling and effectively improves production yield and equipment versatility.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0021] Example 1

[0022] like Figure 1 As shown, a film-tearing claw module includes a frame 1 and a plurality of film-clamping assemblies disposed on the frame 1. The module includes an intermediate film-clamping assembly 2 disposed on the frame 1, and two side film-clamping assemblies 3 symmetrically distributed about the intermediate film-clamping assembly 2 on the side of the intermediate film-clamping assembly 2. In particular, in this embodiment, an auxiliary film-clamping assembly 4 is connected to the frame 1 and located beside the intermediate film-clamping assembly 2 and / or the side film-clamping assembly 3, which cooperates in clamping the film when the intermediate film-clamping assembly 2 and / or the side film-clamping assembly 3 perform the film-tearing action.

[0023] like Figures 1-5 As shown, in this embodiment, the auxiliary clamping assembly 4 includes two independently driven auxiliary clamping claws 41, which are symmetrically distributed on both sides of the central clamping assembly. Each auxiliary clamping claw 41 is connected to an independent clamping claw driver 6. Specifically, the clamping claw driver 6 for the auxiliary clamping claws 41 is a finger-gripping cylinder driver. The advantage of using a finger-gripping cylinder as the driver is its compact structure, fast response, and precise control of the clamping force. This finger-gripping cylinder driver, through the reciprocating motion of its piston, drives the two fingers to synchronously open and close, thereby smoothly and reliably clamping or releasing the edge of the membrane material. This design greatly enhances the module's ability to grasp the membrane head during the initial film-tearing stage, providing a stable starting point for subsequent film-tearing actions.

[0024] Special, such as Figure 7 As shown, an axial angle adjustment component 42 is also provided at the fixed end of the auxiliary film clamping claw 41. The auxiliary film clamping assembly 4 can rotate around the first axis X by the axial angle adjustment component 42 to adapt to different workpiece surface curvatures or inclined film tearing conditions. Specifically, the axial angle adjustment component 42 includes a fixed axis as the rotation center and an arc-shaped waist-shaped hole provided on the mounting base plate. The operator can loosen the locking bolt to rotate the entire auxiliary film clamping claw around the fixed axis to the required angle. At this time, the bolt can slide within the arc trajectory of the waist-shaped hole and relock, thereby realizing stepless adjustment and precise fixation of the pitch angle of the auxiliary film clamping claw.

[0025] like Figure 4 As shown, a slide drive 5 is also provided between the auxiliary film clamping assembly 4 and the frame 1. In this embodiment, the auxiliary film clamping assembly 4 is located at the bottom of the frame 1, and the slide drive 5 drives the auxiliary film clamping assembly 4 to move relative to the frame 1 along the first axis X.

[0026] The slide drive 5 is preferably driven by a cylinder to ensure smooth movement and accurate repeatability. Through program control, the slide drive 5 can drive the entire auxiliary film clamping assembly 4 to perform precise translational movement along a first axis X parallel to the workpiece surface. Furthermore, to prevent damage to the cylinder from film tearing during cantilever operation after the cylinder extends, in this embodiment, all slide drives 5 are equipped with linear guides to enhance structural strength.

[0027] The side clamping film assembly 3 is also connected to a slide drive 5, which drives the side clamping film assembly 3 to move relative to the frame 1 along the second axis Y.

[0028] The aforementioned intermediate clamping assembly 2 and side clamping assembly 3 each include a clamping drive 6 and a main clamping claw 7 located at the output end of the clamping drive 6. Specifically, the main clamping claw 7 of the side clamping assembly 3 and the main clamping claw 7 of the intermediate clamping assembly 2 face the same direction, towards the second axis Y. The auxiliary clamping claw 41 of the auxiliary clamping assembly 4 is perpendicularly distributed to the main clamping claw 7. All main clamping claws 7 move along the Z-axis, and their main function is to provide an upward lifting force during the film tearing process, acting together on the main body area of ​​the membrane. Simultaneously, the horizontally moving auxiliary clamping claw 41 is responsible for laterally clamping and pulling the edges or specific parts of the membrane material.

[0029] And, as Figure 8 The main clamping claw 7 is also provided with an embossed clamping part 71, the surface pattern of which is one of mesh, stripe, or dotted protrusions. The design of this embossed clamping part 71 significantly enhances the friction between the claw and the membrane surface. When the main clamping claw 7 presses down, these tiny mesh, stripe, or dotted protrusions can effectively embed or engage with the membrane surface, greatly increasing the static friction coefficient of the contact surface, thereby preventing relative slippage during tearing.

[0030] like Figure 6 As shown, the fixed end of the side film clamping assembly 3 is also equipped with a two-axis angle adjustment component 32. The side film clamping assembly 3 can rotate around the second axis Y through the two-axis angle adjustment component 32. The two-axis angle adjustment component 32 has the same function as the aforementioned one-axis angle adjustment component 42, both providing additional angular freedom to adapt to complex working surfaces. Specifically, the two-axis angle adjustment component 32 also adopts a structure with an arc-shaped waist-shaped hole and a locking bolt, allowing the operator to loosen the bolt and manually adjust the deflection angle of the side film clamping assembly 3 around the second axis Y, and then re-lock it after adjustment. This design allows the main clamping claws 7 of the two side film clamping assemblies 3 to not only perform clamping movements along the second axis Y, but also their own clamping planes to adaptively fine-tune the angle according to the side surface contour of the workpiece to be peeled.

[0031] As a preferred embodiment, in this embodiment, a number of suction cup transport components 8 for transporting the workpiece can be fixed on the frame 1. The suction cup transport components 8 generate negative pressure through an external vacuum generator (not shown in the figure), thereby reliably adsorbing the workpiece surface and realizing the integration of operations.

[0032] Example 2

[0033] The structure and principle of this embodiment are basically the same as those of Embodiment 1. The difference lies in that, for the film tearing claw module of Embodiment 1, the film tearing device of this embodiment includes a film tearing claw module.

[0034] In this embodiment, the principle is as follows: the above-mentioned film-tearing claw module is installed on a six-axis robotic arm. The middle film clamping component 2 first clamps the film, the six-axis robotic arm pulls the film up by 15mm, the auxiliary film clamping component 4 extends to clamp the film to prevent the film from breaking, and finally the side film clamping component 3 extends to clamp the film, and the six-axis robotic arm continues to move upward to tear off the film.

[0035] Furthermore, the specific operation is as follows: the vacuum suction cup on the film-tearing claw module picks up the product and places it on the positioning fixture 9. The six-axis robotic arm rotates to move the intermediate film clamping assembly 2 to the film-tearing position. After the main film clamping claw 7 of the intermediate film clamping assembly 2 clamps the film, the six-axis robotic arm pulls the film up by 15mm. The slide drive 5 of the auxiliary film clamping assembly 4 extends, and the auxiliary film clamping claw 41 clamps the film. The six-axis robotic arm continues to move upward and rotates at a certain angle to make the edge of the film face upward. The side film clamping assembly 3 extends, and the main film clamping claw 7 of the side film clamping assembly 3 clamps the film. The six-axis robotic arm continues to move upward to tear off the film and put it into the waste film box, and the cycle ends.

[0036] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
