Description

Technical Field

[0001] The utility model belongs to the technical field of new energy, and in particular relates to a visual alignment cutting device. Background Art

[0002] The CCM (catalyst / proton exchange membrane assembly prepared by coating fuel cell catalyst on both sides of the proton exchange membrane), frame membrane and other membrane electrode related products in hydrogen fuel cells are mostly large in size during production and need to be cut into specified sizes according to the actual product size.

[0003] In the related art, the cutting machine relies on manual work to fix one corner of the film on a mechanical hard limit, and then cuts according to the drawing imported into the cutting machine software. The relative position of the film to be cut is based on the mechanical hard limit.

Furthermore, the thin and soft film rests on the hard limits before adsorption, which can lead to some deformation. Furthermore, manual adjustment requires secondary equipment measurement, and the cutting machine must be fine-tuned based on the results, increasing labor costs.

[0057] Research has found that the shortcomings of the existing technology are: CCM, frame membrane and other membrane electrode related products in hydrogen fuel cells are mostly large in size during production, and need to be cut into specified sizes according to the actual product size.

[0058] In the related art, the cutting machine relies on manual work to fix one corner of the film on a mechanical hard limit, and then cuts according to the drawing imported into the cutting machine software. The relative position of the film to be cut is based on the mechanical hard limit.

[0059] Using mechanical hard limits as a reference has limitations. This is primarily due to the fact that they require manual adjustment, which can lead to deviations in material placement. Furthermore, the thin and soft film rests on the hard limits before adsorption, which can lead to some deformation. Furthermore, manual adjustment requires secondary equipment measurement, and the cutting machine must be fine-tuned based on the results, increasing labor costs.

[0060] Because how to prevent the film from deforming when it is positioned before cutting is a technical problem that urgently needs to be solved in this field.

[0061] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0062] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0063] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0064] like Figures 1 to 3As shown, some embodiments provide a visual alignment cutting device, including: a film suction plate 1, which is arranged in a supporting frame, and the film suction plate 1 is suitable for limiting the workpiece; a plurality of negative pressure holes 10 are opened in a matrix on the film suction plate 1, and the plurality of negative pressure holes 10 are connected to a negative pressure fan, and the control module is electrically connected to the negative pressure fan, and is configured to start the negative pressure fan after the workpiece is located on the film suction plate 1 so that the negative pressure holes 10 generate negative pressure to limit the workpiece.

[0065] . After the workpiece is placed on the film suction plate 1, the negative pressure hole 10 is suitable for negatively adsorbing the workpiece to prevent the workpiece from moving freely on the film suction plate 1. The horizontal moving pair 2 is arranged on the support frame and above the film suction plate 1; when the horizontal moving pair 2 drives the visual module 4 to move horizontally, the visual module 4 is suitable for taking pictures of the two diagonal sides of the product, and after determining whether the workpiece is placed on the film suction plate 1, the workpiece is positioned to determine the center of the workpiece. The cutting mechanism 3 is set on the sliding of the horizontal moving pair 2 and is suitable for cutting the workpiece; the visual module 4 is arranged on one side of the cutting mechanism 3; the control module is electrically connected to the horizontal moving pair 2, the cutting mechanism 3 and the visual module 4 respectively, and is configured to control the horizontal moving pair 2 to drive the visual module 4 to move horizontally after the workpiece is limited by the negative pressure of the film suction plate 1, and start the visual module 4 to take pictures of the two diagonal sides of the film, determine the center position of the workpiece and position it, so as to control the cutting mechanism 3 to cut the workpiece downward. The workpiece described in this embodiment is a rectangular film product. Through the coordination of the vision module 4, cutting mechanism 3, and film suction plate 1, a workpiece is placed horizontally on the film suction plate 1, where it is held in place by negative pressure. Once the workpiece is positioned, the vision module 4 moves horizontally to determine the workpiece's center, enabling the cutting blade 35 to quickly and efficiently cut the workpiece. This avoids mechanical hard-positioning, which can lead to tensile deformation during the positioning process. After the vision module 4 locates the workpiece's two diagonal corners, it compares them to a pre-loaded drawing, improving cutting accuracy.

[0066] Reference Attachment Figure 2 The horizontal moving pair 2 includes an X-axis conveying assembly 21 and a Y-axis conveying assembly 22. The X-axis conveying assembly 21 is disposed on either side of the film suction plate 1, with its upper end at a higher level than the film suction plate 1. The Y-axis conveying assembly 22 is mounted on the slide of the X-axis conveying assembly 21 and is perpendicular to the X-axis conveying assembly 21. The X-axis conveying assembly 21 is adapted to drive the Y-axis conveying assembly 22 to move horizontally left and right, while the Y-axis conveying assembly 22 is adapted to drive the cutting mechanism 3 and the vision module 4 to move horizontally forward and backward.

The driver 32 drives the cutting blade 35 downward to completely cut or partially cut the workpiece. The downward movement or upward retraction of the cutting blade 35 is controlled by adjusting the magnetic force of the driver 32. While the vision module 4 is capturing and locating the workpiece, the cutting blade 35 retracts upward, preventing contact with the workpiece. Once the workpiece is located by the vision module 4, the cutting blade 35 extends downward to completely cut or partially cut the workpiece.

[0068] Reference Attachment Figure 2 The visual module 4 includes a positioning block 41, which is disposed on the side wall of the positioning plate 31 and is disposed on one side of the driving member 32; and a visual sensor 42, which is electrically connected to the control module and is disposed on the side wall of the positioning block 41 and is disposed above the film suction plate 1.
