Description

Technical Field

[0001] This utility model relates to the field of film cutting equipment technology, and in particular to a double-layer film cutting equipment. Background Technology

[0002] In fields such as home appliance manufacturing and sheet metal manufacturing, protective films are typically applied to the surface of sheet metal parts. During processing, these films need to be precisely cut using a film-cutting device to meet subsequent assembly or forming requirements. Existing sheet metal film-cutting equipment usually includes a frame, a worktable, and a film-cutting assembly. The frame is often a single-unit frame structure, arranged vertically or horizontally. The worktable is a single horizontal support platform, fixedly installed in the middle or top area of ​​the frame, used to place the sheet metal to be processed. The film-cutting assembly can drive the cutting head to move along the X and Y axes of the worktable, thereby realizing the film-cutting operation on the surface of the sheet metal. However, the worktable and film-cutting assembly of this type of single-layer film-cutting equipment are only configured in a single set, and only one sheet metal can be cut at a time. After cutting one sheet metal, the machine must be stopped, the finished sheet metal removed, and the sheet metal to be processed placed again. The equipment has a long downtime, resulting in low processing efficiency per unit time. To increase production capacity, companies often need to purchase multiple additional machines and arrange them in parallel, which not only significantly increases equipment investment costs but also occupies more workshop production space. It is difficult to balance production efficiency and site utilization, and cannot meet the current demand for mass production in the manufacturing industry. Utility Model Content

The bottom of the support column is fixed to the second top frame, and the top of the support column is fixed to the support frame. The support frame is horizontally arranged, and the second workbench is fixed to the support frame.

[0011] As an improvement to the above solution, the double-layer film-cutting device further includes an upper negative pressure mechanism, which includes a negative pressure branch pipe and a negative pressure main pipe. The second workbench is provided with multiple air holes, which are connected to the negative pressure branch pipe, which are connected to the negative pressure main pipe, and the negative pressure main pipe is connected to an external negative pressure device.

[0012] As an improvement to the above solution, the film-spreading assembly includes a first moving mechanism, a second moving mechanism, and a film-spreading mechanism. The first moving mechanism includes a first moving rail and a first moving seat. The first moving seat is capable of moving along the first moving rail.

[0018] This utility model relates to a double-layer film-cutting device comprising a first frame, a second frame, a first worktable, a second worktable, and at least two film-cutting assemblies. The first frame is positioned below the second frame, the first worktable is mounted on the first frame, and the second worktable is mounted on the second frame. The film-cutting assemblies are respectively mounted on the first and second worktables. By arranging the first and second frames in a stacked configuration, the first and second worktables form upper and lower dual-support platforms, with each support platform corresponding to one of the film-cutting assemblies.

This allows for simultaneous film dicing of multiple boards, reducing equipment downtime and improving processing efficiency per unit time. It also avoids the additional investment required by multiple machines, reducing equipment procurement costs. Furthermore, by replacing the horizontal parallel arrangement with an upper and lower layer structure, it saves horizontal space in the workshop, balances production efficiency and space utilization, and meets the needs of mass production.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] See Figure 1 This utility model discloses a double-layer film-cutting device, including a first frame 1, a second frame 2, a first workbench 3 and a second workbench 4, and a film-cutting assembly 5.

[0025] The first frame 1 and the second frame 2 are arranged in a stacked configuration, with the first frame 1 located below the second frame 2, the first workbench 3 mounted on the first frame 1, and the second workbench 4 mounted on the second frame 2. Existing frames can only support a single workbench, while this embodiment, through its stacked double-frame structure, provides stable support for both the first workbench 3 and the second workbench 4. Simultaneously, it utilizes vertical space instead of the existing horizontally arranged layout of multiple devices, structurally reducing the horizontal footprint of the workshop and avoiding the space waste caused by purchasing additional equipment.

[0026] The number of the film-cutting components 5 is at least two and they are respectively arranged on the first workbench 3 and the second workbench 4. That is, each workbench is equipped with at least one film-cutting component 5. Each film-cutting component 5 can independently perform film-cutting operations on the boards on different workbenches, so that the first workbench 3 and the second workbench 4 can carry out cutting operations simultaneously, thereby simultaneously cutting multiple boards and improving the processing efficiency per unit time. At the same time, since there is no need to purchase multiple single-layer equipment to increase production capacity, the additional investment brought by multiple equipment can be effectively avoided, reducing equipment procurement costs.

[0027] The beneficial effects of this utility model embodiment are as follows:

[0028] This utility model embodiment of the double-layer film-cutting device includes a first frame 1, a second frame 2, a first workbench 3, a second workbench 4, and at least two film-cutting components 5. The first frame 1 is located below the second frame 2, the first workbench 3 is located on the first frame 1, and the second workbench 4 is located on the second frame 2. The film-cutting components 5 are respectively located on the first workbench 3 and the second workbench 4. By arranging the first frame 1 and the second frame 2 in a stacked manner, the first workbench 3 and the second workbench 4 form an upper and lower double-support platform, and each support platform corresponds to... The film-cutting assembly 5 enables the first workbench 3 and the second workbench 4 to simultaneously perform film-cutting operations on boards. This eliminates the need to stop the machine to remove the finished product and place the board to be processed after the film-cutting of a single board is completed, and also eliminates the need to purchase multiple single-layer film-cutting machines for parallel arrangement to increase production capacity. This allows for simultaneous film-cutting of multiple boards, reducing equipment downtime and improving processing efficiency per unit time. It also avoids the additional investment required by multiple machines, reducing equipment procurement costs. Furthermore, by replacing the horizontal parallel arrangement with an upper and lower layer structure, it saves horizontal space in the workshop, balances production efficiency and site utilization, and meets the needs of mass production.

[0029] See Figure 2 The first frame 1 includes a first base frame 11, a first column 12, and a first top frame 13. The first base frame 11 is located at the lower part of the first frame 1 and serves as the bottom support foundation for the first frame 1, distributing the overall weight of the first frame 1, the first worktable 3, and the corresponding slicing assembly 5. The bottom of the first column 12 is vertically fixed to the first base frame 11, and the first top frame 13 is fixed to the top of the first column 12. The first top frame 13 is horizontally arranged, and the first worktable 3 is fixed to the first top frame 13. The horizontal arrangement of the first top frame 13 ensures that the surface of the first worktable 3 is flat, reducing slicing errors.

[0030] The first top frame 13 includes multiple first crossbeams 131, which are horizontally distributed on the first top frame 13 and abut against the first worktable 3, thereby increasing the contact area between the first top frame 13 and the first worktable 3. The first crossbeams 131 support the first worktable 3.

[0031] The second frame 2 includes a second column 21 and a second top frame 22. The second column 21 is vertically arranged, and its length is greater than that of the first column 12, thereby raising the second worktable 4 as a whole to provide sufficient operating space for the dicing assembly 5 on the first worktable 3. The bottom of the second column 21 is fixedly connected to the first base frame 11, and the top of the second column 21 is fixedly connected to the second top frame 22. The second worktable 4 is mounted on the second top frame 22. The second top frame 22 serves as a transition support structure, which can evenly transfer the weight of the second worktable 4 to the second column 21 and then to the first base frame 11. This prevents the second worktable 4 from tilting due to uneven force caused by being directly fixed to a simple support structure, ensuring the flatness of the second worktable 4 and providing a foundation for the stable placement and precise dicing of the workpiece to be processed.

[0032] The second frame 2 also includes a support column 23 and a support frame 24. The bottom of the support column 23 is fixed to the second top frame 22, and the top of the support column 23 is fixed to the support frame 24. The support frame 24 is horizontally arranged, and the second workbench 4 is fixed to the support frame 24. By raising the height of the second workbench 4, the support frame 24 can reserve sufficient space below the second workbench 4 for installing the upper negative pressure mechanism 6 and other necessary auxiliary mechanisms. This avoids spatial conflicts between the auxiliary mechanisms and the first workbench 3, and eliminates the need to additionally expand the lateral dimensions of the equipment to accommodate the mechanisms. This further ensures the independence and coordination of operations on both upper and lower levels, while maintaining the overall compact vertical layout advantage of the equipment.

[0033] See Figure 3 The double-layer film-cutting device further includes an upper negative pressure mechanism 6, which is used to fix the plates on the second workbench 4. Specifically, the upper negative pressure mechanism 6 includes a negative pressure branch pipe 61 and a negative pressure main pipe 62. The second workbench 4 is provided with multiple air holes 41, which are connected to the negative pressure branch pipe 61 and the negative pressure branch pipe 61 are connected to the negative pressure main pipe 62. The negative pressure main pipe 62 is connected to an external negative pressure device. The negative pressure branch pipe 61 is connected to the multiple air holes 41 through a sealing structure (not shown in the figure) to form a sealed air path. The negative pressure device provides negative pressure through the negative pressure main pipe 62 and the negative pressure branch pipe 61. The negative pressure is conducted to the air holes 41, which can stably adsorb the plates on the second workbench 4, thereby fixing the plates on the second workbench 4. This fixing method differs from the existing technology that uses mechanical clamps to fix plates. Existing mechanical clamps are prone to causing indentation damage to the surface of the plates, and clamp adjustment is time-consuming, which may prolong equipment downtime. Negative pressure adsorption does not need to contact the surface of the plates, which can avoid the risk of damage. At the same time, the fixing response speed is fast and it is suitable for batch operation needs.

[0034] See Figure 4 The film-cutting assembly 5 includes a first moving mechanism 51, a second moving mechanism 52, and a film-cutting mechanism 53. The first moving mechanism 51 includes a first moving rail 511 and a first moving seat 512. The first moving seat 512 can move along the first moving rail 511, providing a first-direction moving base for the film-cutting assembly 5. The second moving mechanism 52 includes a second moving rail 521 and a second moving seat 522. The second moving rail 521 is connected to the first moving seat 512, and the length direction of the second moving rail 521 is perpendicular to the length direction of the first moving rail 511. The perpendicularly arranged dual rails can form an orthogonal moving path in a plane (such as the X-axis and Y-axis directions), covering the entire surface area of ​​the first worktable 3 or the second worktable 4. The second moving seat 522 can move along the second moving rail 521, and the film-cutting mechanism 53 is disposed on the second moving seat 522. Through the coordinated movement of the first moving seat 512 and the second moving seat 522, the film-cutting mechanism 53 can be driven to accurately reach any cutting position on the worktable, ensuring the accuracy of the cutting trajectory.

[0035] See Figure 4 The first workbench 3 has two cutting mechanisms 53, each located at one end of the first workbench 3. The second workbench 4 also has two cutting mechanisms 53, each located at one end of the second workbench 4. Existing single-cutting-mechanism 53 workbenches can only cut one piece at a time, limiting the processing capacity per unit time and making it difficult to meet the needs of mass production. In this embodiment, each workbench is equipped with two symmetrical cutting mechanisms 53, structurally enabling simultaneous cutting of multiple pieces on a single workbench. Furthermore, each workbench can simultaneously activate two of the aforementioned scribing mechanisms 53, enabling simultaneous scribing of two workpieces. On one hand, the symmetrical arrangement allows the forces generated by the two scribing mechanisms 53 during operation to balance each other, avoiding uneven force distribution and slight deformation of the workbench due to unilateral mechanism operation, which would affect scribing accuracy. On the other hand, activating two scribing mechanisms 53 simultaneously doubles the processing efficiency of a single workbench. Combined with the structure of the upper and lower double-layer workbench, the entire equipment can simultaneously scribble four workpieces (two per layer), significantly improving efficiency compared to existing single-layer, single-mechanism equipment. Moreover, it eliminates the need to increase the number of devices to increase production capacity, further reducing equipment investment costs and floor space requirements, and better meeting the needs of mass production in the manufacturing industry for efficient and compact equipment.

[0036] See Figure 1The double-layer film-cutting equipment also includes an electrical control component 7, which comprises a first electrical control box 71 and a second electrical control box 72. The first electrical control box 71 is electrically connected to the film-cutting component 5 on the first workbench 3, and the second electrical control box 72 is electrically connected to the film-cutting component 5 on the second workbench 4. The first electrical control box 71 is only electrically connected to the film-cutting component 5 on the first workbench 3 and is specifically responsible for controlling the lower layer film-cutting operation. The second electrical control box 72 is only electrically connected to the film-cutting component 5 on the second workbench 4 and is specifically responsible for controlling the upper layer film-cutting operation. The upper and lower layer electrical control systems operate independently. When one of the electrical control boxes malfunctions, only the corresponding layer's operation needs to be suspended, while the other layer can continue to operate normally, significantly reducing the overall equipment downtime and effectively improving production continuity.

[0037] See Figure 1 A placement space (not shown in the attached figure) is provided between the first column 12 and the second column 21. The placement space is respectively located at both ends of the first frame 1. The first electrical control box 71 and the second electrical control box 72 are respectively located in the placement space at both ends of the first frame 1. This not only avoids the risk of damage to the exposed electrical control box, but also makes the overall structure of the equipment more compact. At the same time, the electrical control boxes are located at both ends to balance the weight of the equipment and prevent the center of gravity of the equipment from shifting due to the placement of heavy objects on one side, thus ensuring the stability of the equipment placement.

[0038] See Figure 1 The first frame 1 also includes a first enclosure 14, which is arranged between each of the first columns 12. After the enclosure 14 is arranged, it forms a closed protective area between each of the first columns 12, effectively preventing foreign objects from entering the interior of the first frame 1, and preventing operators from accidentally touching the moving parts inside the frame, thus improving operational safety. The second frame 2 also includes a second enclosure 25, which is arranged between each of the support columns 23. After the enclosure 25 is arranged, it can effectively protect the pipes, lines and other components between the support columns 23, preventing damage from external forces, and avoiding the layout chaos caused by exposed pipes. It ensures the stable operation of the upper negative pressure mechanism 6, thereby ensuring the reliability of the plate adsorption on the second workbench 4, and indirectly ensuring the accuracy of the upper slicing operation.

[0039] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
