[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1, reference Figure 1 - Figure 3 , which is the first embodiment of the present invention, provides a laser cutting device for membrane switch processing that is easy to position. The device includes: a supporting unit 100, a positioning and fixing unit 200, and a cutting unit 300.

[0031] The support unit 100 includes an operating table 101;

[0032] The positioning and fixing unit 200 includes a fixing assembly 201 disposed on the operating table 101 for limiting the position of the membrane switch, a positioning assembly 203 disposed on top of the fixing assembly 201 for ensuring stability during the membrane switch cutting process, and a driving assembly 202 for driving the fixing assembly 201 and the positioning assembly 203;

[0033] The cutting unit 300 includes a cutting assembly 301 disposed on the top of the operating table 101 and used to cooperate with the fixing assembly 201 to cut the membrane switch. When laser cutting the membrane switch, the operator places the membrane switch to be cut on the placement cutting plate 2013 on the top of the fixing assembly 201. At the same time, the positioning assemblies 203 on both sides of the membrane switch limit the membrane switch so that it can only be placed flat on the top middle position of the fixing assembly 201. After the placement is completed, the driving assembly 202 starts to drive, so that the Y-shaped rotating member 2018 on the fixing assembly 201 starts to retract from the periphery to the middle, and during the movement of the Y-shaped rotating member 2018, the membrane switch is placed on the cutting plate 2013. During the cutting process, the receiving plate 2012 blocks the Y-shaped rotating member 2018, causing the Y-shaped rotating member 2018 to start rotating and adjusting, so that the Y-shaped rotating member 2018 can be stably engaged with the membrane switch placed on the top of the cutting plate 2013, and the membrane switch is accurately fixed. In the process of the movement of the Y-shaped rotating member 2018, the positioning component 203 is also squeezed and driven to flip, and is further fixed on the membrane switch on the top of the fixing component 201, ensuring the stability of the membrane switch during the cutting process. After the membrane switch is fixed, the cutting component 301 starts to adjust the position and angle to cut the membrane switch on the top of the fixing component 201.

[0034] During use, when laser cutting the membrane switch, the operator places the membrane switch to be cut on the placement cutting plate 2013 on the top of the fixed component 201, and at the same time, the positioning components 203 on both sides of the membrane switch are limited, so that the membrane switch can only be placed flat on the top middle position of the fixed component 201. After the placement is completed, the driving component 202 starts to drive, so that the Y-shaped rotating member 2018 on the fixed component 201 starts to retract from the four sides to the middle, and in the process of the movement of the Y-shaped rotating member 2018, the receiving plate 2012 blocks the Y-shaped rotating member 2018, so that the Y-shaped rotating member 2018 starts to rotate and adjust, so that the Y-shaped rotating member 2018 can be stably engaged with the membrane switch on the top of the placement cutting plate 2013, and the membrane switch is accurately fixed. During the movement of the rotating part 2018, the positioning component 203 is also squeezed and driven to flip, and is engaged with the membrane switch on the top of the fixing component 201 for further fixation, ensuring the stability of the membrane switch during the cutting process. After the membrane switch is fixed, the cutting component 301 starts to adjust the position and angle to cut the membrane switch on the top of the fixing component 201, effectively preventing it from moving during cutting. The fixing component uses a rolling extrusion method to fix the membrane switch, avoiding damage to the membrane caused by direct extrusion of traditional clamps. At the same time, the cutting component can adjust the position at multiple angles to accurately cut the membrane switch, further improving the cutting accuracy and quality, improving the processing quality of the membrane switch, reducing the cutting deviation and scrap rate caused by unstable fixation, reducing production costs, and improving the adaptability of the equipment and the convenience of operation.

[0035] Example 2, reference Figure 1 - Figure 7, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a fixed component 201 includes a support plate 2011 arranged inside the operating table 101, a receiving plate 2012 arranged on the top of the support plate 2011, a cutting plate 2013 arranged on the top of the receiving plate 2012, a guide rail 2014 arranged at the bottom of the support plate 2011, and a movable plate 2015 slidably arranged on the guide rail 2014, and the movable plate 2015 is connected to the driving component 202, a fixed part 2016 is provided on the top of the movable plate 2015, a rotating rod 2017 is provided inside the fixed part 2016, a Y-shaped rotating part 2018 is provided on the top of the rotating rod 2017, and the Y-shaped rotating part The internal rolling element of 2018 is provided with a fixed roller 2019, and the fixed roller 2019 is slidably connected to the cutting plate 2013. The driving assembly 202 includes a rotating shaft 1 2021 rotatably provided at the bottom of the support plate 2011, a linkage rod 1 2022 provided on the outer diameter of the rotating shaft 1 2021, a linkage rod 2023 rotatably provided on the linkage rod 1 2022, and a rotating shaft 2 2024 rotatably provided at the other end of the linkage rod 2023, and the rotating shaft 2 2024 is connected to the movable plate 2015. An electric push rod 2025 is provided at the bottom of the support plate 2011, and the electric push rod 2025 is fixedly connected to the movable plate 2015. Before the membrane switch is laser cut, the membrane switch is moved by The membrane switch is placed on the top of the cutting plate 2013. Under the limit of the positioning assembly 203, the membrane switch is placed flat on the middle position of the cutting plate 2013. At the same time, the electric push rod 2025 is driven to make the movable plate 2015 start to move toward the middle with the fixed part 2016, and at the same time, the linkage rod 2023 and the linkage rod 1 2022 start to rotate and adjust along the rotation axis 1 2021, so that the movable plate 2015 on the other side also moves toward the middle at the same time, so that the movable plates 2015 on both sides move toward the middle with the fixed part 2016 at the same time, and during the movement of the fixed part 2016, the rotating rod 1 2017 inside the fixed part 2016 also moves with the Y-shaped rotating part 201 8 moves together, and during the movement, the bottom of the Y-shaped rotating member 2018 is blocked by the receiving plate 2012, so that the Y-shaped rotating member 2018 and the rotating rod 1 2017 start to rotate inside the fixing member 2016, thereby adjusting the engaging position of the Y-shaped rotating member 2018, until the position adjustment of the Y-shaped rotating member 2018 is completed, so that the fixed roller 2019 rolls and squeezes the membrane switch placed on the top of the cutting plate 2013, and fixes the four corners of the membrane switch at the same time. At the same time, because the fixed roller 2019 is rolling and squeezing the membrane switch, the membrane switch can be pulled tight when rolling, and the rolling and squeezing fixation will not damage the surface of the membrane switch, ensuring stability during subsequent laser cutting.

[0036] Compared with Example 1, further, the positioning assembly 203 includes a second rotating rod 2031 rotatably arranged inside the receiving plate 2012, connecting rods 2032 arranged at both ends of the second rotating rod 2031, and a coil spring 2033 arranged on the outer diameter of the connecting rod 2032, and the connecting rod 2032 rotates inside the receiving plate 2012, the coil spring 2033 is fixedly connected to the receiving plate 2012, the outer diameter of the second rotating rod 2031 is provided with a collar 2034, and the top of the collar 2034 is provided with a Extrusion block 2035, the outer diameter of the second rotating rod 2031 is provided with a T-shaped sleeve rod 2036, the top of the T-shaped sleeve rod 2036 is provided with a pressure plate 2037, and the pressure plate 2037 cooperates with the Y-shaped rotating member 2018 to fix the membrane switch. In the process of the Y-shaped rotating member 2018 and the fixed roller 2019 fixing the membrane switch placed on the top of the cutting plate 2013, the Y-shaped rotating member 2018 squeezes the extrusion block 2035 placed inside the cutting plate 2013 when moving, so that the extrusion The block 2035 and the collar 2034 turn over together with the second rotating rod 2031 and the connecting rod 2032, and when the connecting rod 2032 turns over, the coil spring 2033 is squeezed and twisted, and the T-shaped sleeve 2036 and the pressure plate 2037 on the second rotating rod 2031 turn over together with the second rotating rod 2031, so that the pressure plate 2037 is engaged with the cutting plate 2013, thereby pressing the two membrane switches on the top of the cutting plate 2013. The Y-shaped rotating member 2018 is further fixed on both sides to ensure the stability of the membrane switch during laser cutting. After the cutting is completed, the driving assembly 202 drives the Y-shaped rotating member 2018 to expand to both sides, thereby releasing the fixation of the membrane switch. When the Y-shaped rotating member 2018 expands back to the extrusion block 2035 and loses the extrusion, the coil spring 2033 also loses the extrusion, so that the connecting rod 2032 brings the rotating rod 2031 and the pressure plate 2037 away from the top of the cutting plate 2013 and returns to its original position, ready for the next fixation.

[0037] During use, before laser cutting the membrane switch, the membrane switch is placed on the top of the cutting plate 2013. Under the limit of the positioning component 203, the membrane switch is placed flat on the middle position of the cutting plate 2013. At the same time, the electric push rod 2025 is driven to make the movable plate 2015 start to move toward the middle with the fixed part 2016, and at the same time, the linkage rod 2023 and the linkage rod 1 2022 also start to rotate and adjust along the rotation axis 1 2021, so that the movable plate 2015 on the other side also moves toward the middle at the same time, so that the movable plates 2015 on both sides bring the fixed part 2016 closer to the middle at the same time, and during the movement of the fixed part 2016, the rotating rod 1 2023 inside the fixed part 2016 is rotated and adjusted. 17 also moves with the Y-shaped rotating member 2018, and during the movement, the bottom of the Y-shaped rotating member 2018 is blocked by the receiving plate 2012, so that the Y-shaped rotating member 2018 and the rotating rod 1 2017 begin to rotate inside the fixing member 2016, thereby adjusting the engaging position of the Y-shaped rotating member 2018, until the position adjustment of the Y-shaped rotating member 2018 is completed, so that the fixed roller 2019 rolls and squeezes the membrane switch placed on the top of the cutting plate 2013, and fixes the four corners of the membrane switch at the same time. At the same time, because the fixed roller 2019 is rolling and squeezing the membrane switch, the membrane switch can be pulled tight when rolling, and the rolling and squeezing fixation will not damage the surface of the membrane switch, ensuring stability during subsequent laser cutting.

[0038] In the process of the Y-shaped rotating member 2018 and the fixed roller 2019 fixing the membrane switch placed on the top of the cutting plate 2013, the Y-shaped rotating member 2018 presses the squeezing block 2035 placed inside the cutting plate 2013 when moving, causing the squeezing block 2035 and the ring 2034 to flip together with the rotating rod 2031 and the connecting rod 2032, and when the connecting rod 2032 flips, it squeezes the coil spring 2033, causing the coil spring 2033 to be squeezed and twisted, and the T-shaped sleeve rod 2036 and the pressure plate 2037 on the rotating rod 2031 flip together with the rotating rod 2031, so that the pressure Plate 2037 is engaged with the cutting plate 2013, thereby further fixing the two sides of the membrane switch on the top of the cutting plate 2013, ensuring the stability of the membrane switch during laser cutting. After the cutting is completed, the drive assembly 202 drives the Y-shaped rotating member 2018 to expand to both sides, thereby releasing the fixation of the membrane switch. When the Y-shaped rotating member 2018 expands back and the extrusion block 2035 loses its extrusion, the coil spring 2033 also loses its extrusion, causing the connecting rod 2032 to carry the rotating rod 2031 and the pressure plate 2037 away from the top of the cutting plate 2013 and return to its original position, ready for the next fixation.

[0039] The remaining structures are the same as those of Example 1.

[0040] Example 3, reference Figure 1 - Figure 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the cutting component 301 includes a support member 3011 arranged on the top of the operating table 101, a driving member 3012 arranged inside the support member 3011, a moving part 3013 arranged at the output end of the driving member 3012, a laser cutting member 3014 arranged on the moving part 3013, and a control member 3015 arranged on one side of the support member 3011. After the driving member 202 drives the fixing member 201 and the positioning member 203 to position and fix the membrane switch, the control member 3015 controls the driving member 3012 to start driving the moving part 3013 to adjust the height position. At the same time, the laser cutting member 3014 also adjusts its left and right position along the moving part 3013, so that the laser cutting member 3014 can cut the membrane switch on the top of the fixing member 201 in multiple directions and angles.

[0041] During use, after the driving component 202 drives the fixing component 201 and the positioning component 203 to position and fix the membrane switch, the control component 3015 controls the driving component 3012 to start driving the moving part 3013 to adjust the height position. At the same time, the laser cutting component 3014 is also adjusted left and right along the moving part 3013, so that the laser cutting component 3014 can cut the membrane switch on the top of the fixing component 201 in multiple directions and angles, solving the problems of unstable positioning, easy damage, and difficult to control clamping force in the prior art. The cutting component 301 can adjust the position at multiple angles and accurately cut the membrane switch, further improving the cutting accuracy and quality, improving the processing quality of the membrane switch, reducing the cutting deviation and scrap rate caused by unstable fixation, reducing production costs, and improving the adaptability of the equipment and the convenience of operation.

[0042] The remaining structures are the same as those of Example 2.
