Description

Technical Field

[0001] This utility model relates to the technical field of mask plate fixing, specifically to a mask plate fixing device with adjustable tension mesh. Background Technology

[0002] In the production process of electronic cigarette atomizers, the tension and stability of the mask plate are crucial to the performance of electronic cigarettes. Therefore, it is necessary to perform a mesh-stretching operation on the mask plate. However, the existing adjustable mesh-stretching mask plate fixing device still has certain defects in use.

[0003] During use, the existing mask template is not fixed stably, which can easily cause wrinkles and reduce the accuracy of the mesh during the stretching process, thus reducing the quality of the finished mask template.

[0004] To overcome the above-mentioned defects, prior art 1 (Chinese patent application number 201921843623.X, application date 2019-10-30) provides a fine metal mask plate, a mask device, and a screen-stretching device. The fine metal mask plate includes a mask strip body, which is elongated and includes two opposing long sides and two opposing short sides. At least three skirts are arranged at intervals along the extending direction of each short side. This fine metal mask plate, mask device, and screen-stretching device can reduce wrinkles in the mask plate screen-stretching process. To reduce sag and improve the accuracy of mesh stretching, in the process of stretching fine metal photomasks, at least three grippers in the stretching equipment have two end grippers corresponding to the two end skirts on the short side, which engage with the end skirts to apply stretching force to the two end skirts. The middle gripper located in the middle of the short side does not engage with the middle skirt, but only serves as a support platform for the photomask strip, thus supporting the photomask strip. In this way, the photomask can deform freely under the stretching force, reducing the generation of wrinkles. At the same time, it provides some support for the middle part of the photomask strip, which can reduce sag and improve the stretching accuracy.

[0005] While existing technologies can improve the accuracy of mesh stretching, during operation, the three grippers on the fixture hold and fix the side of the mask plate. The inconsistent driving of the three grippers can easily lead to uneven clamping force, which affects the stability of the mask plate. Excessive pressure can easily cause local wear on the mask plate, thereby affecting its performance. Furthermore, the fixture can only hold the side of the mask plate, resulting in uneven force on the mask plate around its perimeter, which reduces the efficiency and quality of subsequent mesh stretching operations.

[0006] To address the aforementioned issues, there is an urgent need for innovative design based on the existing adjustable photomask fixing device. Therefore, we proposed an adjustable photomask fixing device that can effectively solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide an adjustable mask fixing device for screen tensioning, in order to solve the problems mentioned in the background art. Currently, the three jaws of the clamps on the market hold and fix the side of the mask, but the three jaws are driven inconsistently, which can easily lead to uneven clamping force, thus affecting the stability of the mask. Excessive pressure can easily cause local wear of the mask, thereby affecting the performance of the mask. Furthermore, the clamps can only hold the side of the mask, resulting in uneven force on the mask around its perimeter, which leads to reduced efficiency and quality in the subsequent screen tensioning operation.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an adjustable mask fixing device, comprising a fixed platform, a limiting seat connected to the fixed platform via a support plate, and a lower clamping plate provided on the limiting seat; a lifting block connected inside the limiting seat via an auxiliary component, the lifting block being sleeved on the outside of a guide rod, the guide rod being installed inside the cavity of a storage seat, the storage seat being symmetrically installed on the limiting seat, and an upper clamping plate connected to the side end of the lifting block via a lifting plate, the upper clamping plate being adapted to the lower clamping plate.

[0009] Preferably, the auxiliary component includes a rotating shaft that is installed through the inside of the limiting seat, the outer side of the rotating shaft is connected to the bottom of the lifting block by a connecting rope, and a first spring is sleeved on the outer side of the guide rod.

[0010] Preferably, a driving assembly is installed on the side end of the limiting seat, and the driving assembly includes a limiting plate installed on the side end of the limiting seat.

[0011] Preferably, a limiting groove is provided on the side end of the limiting plate, and the limiting groove is provided in a ring shape.

[0012] Preferably, the rotating shaft passes through the limiting plate and is connected to a handle, a moving rod is connected through the handle, the moving rod is adapted to the limiting groove, and a second spring is sleeved on the outside of the moving rod.

[0013] Preferably, a rotating assembly is installed at the bottom of the fixed platform, the rotating assembly including a motor installed at the bottom of the fixed platform, and the output end of the motor is connected to a turntable.

[0014] Preferably, the bottom of the turntable is connected to a movable block via a rotating component, the rotating component being L-shaped, and the upper end of the movable block being connected to the bottom of the support plate.

[0015] Preferably, a slider is installed at the bottom of the movable block, the slider is slidably connected inside the slide groove, and the slide groove is formed on the surface of the fixed platform.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The adjustable mask fixing device for screen tensioning uses an upper clamping plate under the lifting plate and a lower clamping plate on the limiting seat to quickly clamp the mask. The pair of clamping structures operate through the same drive, and the side ends of the mask are clamped in an all-around and balanced manner, ensuring uniform force on the mask during subsequent screen tensioning operations and reducing localized wear on the mask. The specific details are as follows:

[0017] (1) The clamping structure operates through the same drive, reducing the inconvenience caused by multiple operations. The side end of the mask plate is clamped in all directions and evenly through the clamping structure, ensuring that the mask plate is subjected to uniform force during the subsequent meshing operation.

[0018] (2) When it is necessary to rotate the rotating shaft, move the moving rod outward so that the moving rod moves out of the limiting groove of the limiting plate. The whole process is simple to operate and greatly saves the preparation time. The rotating shaft is rotated by the handle, which improves the accuracy of the operation.

[0019] (3) Release the moving rod so that the moving rod rebounds through the cooperation of the second spring, thereby causing the moving rod to be locked into the limit groove. The handle of the drive component is restricted, reducing the inconvenience caused by poor rotation stability and reducing the problem of angle deviation caused by accidental contact.

[0020] (4) The motor output end of the rotating component drives the turntable to rotate, so that the bottom of the turntable drives the moving block to rotate through the rotating parts. This not only ensures the stability of the moving block's movement path, but also reduces the offset problem caused by uneven force.

[0021] (5) The moving blocks can be spread out or tightened by rotating the turntable in different directions. This not only reduces the time and effort required for installation due to limited space, but also facilitates the mesh stretching operation after the mask plate is clamped, reducing the problem of reduced mesh stretching quality caused by local tension.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] In this embodiment, to improve the service life of the photomask, a limiting operation is performed by the upper clamping plate 12 and the lower clamping plate 13. The purpose is to reduce the problem of localized wear on the photomask. Figures 1-3The technical solution shown includes a fixed platform 1, a limiting seat 3 connected to the fixed platform 1 via a support plate 2, a lower clamping plate 13 on the limiting seat 3, a lifting block 6 connected inside the limiting seat 3 via an auxiliary component, the lifting block 6 being sleeved on the outside of a guide rod 7, the guide rod 7 being installed inside a cavity 9 of a storage seat 8, the storage seat 8 being symmetrically installed on the limiting seat 3, an upper clamping plate 12 connected to the side end of the lifting block 6 via a lifting plate 11, the upper clamping plate 12 being adapted to the lower clamping plate 13, and the auxiliary component including a rotating shaft 4 penetrating inside the limiting seat 3, the rotating shaft 4 having a lower clamping plate 13 connected to the lower clamping plate 13 via a support plate 2. The connecting rope 5 is connected to the bottom of the lifting block 6. A first spring 10 is sleeved on the outside of the guide rod 7. The support plate 2 on the fixed platform 1 facilitates the support and fixation of the limiting seat 3, resulting in high overall support stability and reducing displacement deviation caused by unstable support during subsequent operations. At this time, the mask plate is moved to the position between the upper clamping plate 12 and the lower clamping plate 13. The rotation of the rotating shaft 4 causes the connecting rope 5 to be wound up, causing the lifting block 6 at the end of the connecting rope 5 to move on the guide rod 7. The guide rod 7 is set inside the cavity 9 of the placement seat 8, facilitating the descent of the lifting block 6. The downward movement of the lifting plate 11 not only improves the stability of the lifting block 6's movement but also makes full use of the internal space, achieving a compact and efficient structure. This allows the upper clamping plate 12 under the lifting plate 11 and the lower clamping plate 13 on the limiting seat 3 to quickly clamp the mask plate, improving the convenience of clamping operations, effectively saving operation time, and increasing work efficiency. The symmetrically arranged storage seats 8 facilitate the clamping of the mask plate's side end through a pair of clamping structures, and the pair of clamping structures are operated by the same drive, reducing the inconvenience caused by requiring multiple operations. The end clamping structure achieves omnidirectional and balanced clamping, ensuring uniform force on the mask plate during subsequent screen stretching operations. This reduces localized wear on the mask plate and minimizes the reduction in accuracy caused by axial clamping, thereby improving the overall efficiency and quality of the operation. Since the guide rod 7 is fitted with a first spring 10, the mask plate can be rotated through the rotating shaft 4 after the screen stretching operation, allowing the first spring 10 to drive the lifting block 6 back to its initial position. This reduces the inconvenience of disassembly due to cumbersome setup operations. The overall structure is simple and quick, facilitating installation and maintenance.

[0033] Example 2:

[0034] In this embodiment, to improve overall ease of operation, a drive component is used. The purpose is to reduce operational inconvenience caused by poor rotational stability. Specifically, as follows... Figures 1-4As shown, a drive assembly is installed on the side of the limiting seat 3. The drive assembly includes a limiting plate 14 installed on the side of the limiting seat 3. A limiting groove 15 is formed on the side of the limiting plate 14. The limiting groove 15 is annular. A rotating shaft 4 passes through the limiting plate 14 and is connected to a handle 16. A moving rod 17 is connected through the handle 16. The moving rod 17 is adapted to the limiting groove 15. A second spring 18 is sleeved on the outside of the moving rod 17. When it is necessary to rotate the rotating shaft 4, the moving rod 17 is moved outward, so that the moving rod 17 moves out of the limiting groove 15 of the limiting plate 14, quickly releasing the restriction on the rotating shaft 4. The whole process is simple to operate and greatly saves the operation preparation time. At this time, the handle 16 is... This drives the rotating shaft 4 to rotate, and the handle 16 facilitates the application of force. By driving the rotating shaft 4 to rotate through the handle 16, the amplitude and speed of rotation can be precisely controlled, improving the accuracy of operation. When the desired angle is reached, the moving rod 17 is released, causing the moving rod 17 to rebound through the cooperation of the second spring 18, thereby causing the moving rod 17 to engage inside the limiting groove 15. At this time, the handle 16 is restricted, reducing the inconvenience caused by poor rotation stability. This not only reduces the problem of angle deviation caused by accidental contact, but also eliminates the need for operators to perform complex secondary calibration and fixing operations, simplifying the operation process, reducing labor intensity, and improving the smoothness and continuity of the overall operation.

[0035] Example 3:

[0036] In this embodiment, to improve the overall efficiency of the netting operation, a rotating component is used. The purpose is to reduce the problem of reduced netting quality caused by localized tension. Specifically, as follows... Figures 5-7As shown, a rotating assembly is installed at the bottom of the fixed platform 1. The rotating assembly includes a motor 21 installed at the bottom of the fixed platform 1. The output end of the motor 21 is connected to a turntable 22. The bottom of the turntable 22 is connected to a moving block 24 via a rotating component 23. The rotating component 23 is L-shaped. The upper end of the moving block 24 is connected to the bottom of the support plate 2. A slider 19 is installed at the bottom of the moving block 24. The slider 19 is slidably connected inside a slide groove 20. The slide groove 20 is formed on the surface of the fixed platform 1. When the motor 21 is turned on, the turntable 22 is rotated through the output end of the motor 21, causing the bottom of the turntable 22 to rotate the moving block 24 via the rotating component 23. Since the slider 19 is installed at the bottom of the moving block 24 and is slidably connected to the support plate 2, the moving block 24 rotates. The sliding groove 20 inside the fixed table 1 not only ensures the stability of the moving path of the moving block 24, but also reduces the offset problem caused by uneven force. The moving block 24 can be opened or tightened by the rotation of the turntable 22 in different directions. When it is opened, ample space is quickly made between the components, which not only provides an extremely convenient operating environment for the installation of the mask plate, but also reduces the time and effort of installation caused by the limited space, improves the assembly efficiency of the equipment, and facilitates the screen stretching operation after the mask plate is clamped. The overall tightening and opening operation is evenly forceful, reducing the problem of reduced screen stretching quality caused by local tension. The contents not described in detail in this specification are the prior art known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
