A detection component is installed within the circumferential rotating component. In the aforementioned application, when the equipment needs to operate continuously, the carrier board needs to be manually placed and fixed inside the fixed platform each time a cut is made, reducing the efficiency of continuous operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cutting device for precision carrier plate processing, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides a cutting device for precision carrier plate processing, including a support frame, an equipment housing fixedly connected to the top center of the support frame, a conveyor belt device mounted on the top of the support frame, a Y-axis mobile device mounted inside the equipment housing, an X-axis mobile device mounted inside the Y-axis mobile device, a movable laser cutting head mounted on the outside of the X-axis mobile device, a fixed platform placed on the top of the conveyor belt device, and a maintenance door hinged to the top of the equipment housing. An electric push rod is fixedly connected to the front and rear sides of the inner side of the equipment housing. Multiple sliding grooves are formed on the inner surface of the fixed platform. A slider is slidably connected inside each sliding groove. A trigger plate is fixedly connected to the end of every two sliders away from the center of the fixed platform. A spring is fixedly connected between the trigger plate and the outer surface of the fixed platform. A positioning plate is fixedly connected to the top of the end of each slider near the center of the fixed platform. A limit slider is fixedly connected to the front surface of the positioning plate. Multiple pressure sensors are fixedly connected to the front surface of the positioning plate. An L-shaped trigger plate is fixedly connected to the left side of the trigger plate. A sliding groove is formed inside the left side of the fixed platform. A triangular slider is slidably connected inside the sliding groove. A positioning plate is fixedly connected to the top of the end of the triangular slider near the center of the fixed platform. A spring is fixedly connected between the positioning plate and the inner wall surface of the fixed platform. Positioning plate one and positioning plate two are set up. When the conveyor belt equipment moves the fixed platform to the center of the equipment shell, the electric push rod, trigger plate, slider, slide groove one, L-shaped trigger plate one, triangular slider, and slide groove two work together to make positioning plate one contact the front side of the carrier plate first, fixing the Y-axis position of the carrier plate. Positioning plate two moves to the right, fixing the X-axis position of the carrier plate. This ensures that the carrier plate is always close to the inner edge inside the fixed platform, automatically positioning and fixing the carrier plate before cutting. This saves manpower, makes positioning of the cutting equipment more convenient, and improves the continuous operation efficiency of the equipment.

[0006] According to the above technical solution, a precision carrier plate is placed inside the fixed platform, and a guide groove is provided on the front surface of the precision carrier plate. The inside of the guide groove is slidably connected to the outside of the limiting slider.

[0007] According to the above technical solution, the height of the first positioning plate is greater than the thickness of the precision carrier plate, and the movement trajectory of the first positioning plate does not contact the movement trajectory of the second positioning plate.

[0008] According to the above technical solution, the outer sides of the positioning plate one and the positioning plate two are fixedly connected with elastic buffer pads, and the bottom heat dissipation component is assembled inside the fixed platform.

[0009] According to the above technical solution, the bottom heat dissipation assembly includes an L-shaped trigger plate II, a movable block, a rack, a fixed slider, a slide groove III, a spring III, a gear, a rotating shaft I, an air inlet sealing plate, an air inlet, an air inlet pump, an air inlet pipe, and a bottom air duct. The L-shaped trigger plate II is fixedly connected to the right side of the trigger plate. A fixed slider is fixedly connected to the right surface of the fixed platform block. A movable block is slidably connected to the outside of the fixed slider. A slide groove III is formed on the top of the movable block. The outside of the fixed slider is slidably connected to the inside of the slide groove III. A spring is fixedly connected between the left side and the top left side of the movable block. A rack is fixedly connected to the bottom of the movable block. A bottom air duct is opened on the inner bottom surface of the fixed platform. An air inlet is fixedly connected to the right side of the fixed platform. A rotating shaft is rotatably connected through the air inlet. A gear is fixedly connected to the bottom of the rotating shaft. The rack meshes with the gear. An air inlet sealing plate is fixedly connected to the outer side of the rotating shaft. An air inlet pump is fixedly connected to the right side of the air inlet. An air inlet pipe is fixedly connected to the top of the air inlet pump. A bottom heat dissipation component is installed. When the carrier plate is being cut, a large amount of heat will accumulate inside, which can easily cause deformation and damage to the internal circuitry. In conjunction with the L-shaped trigger plate II, movable block, rack, fixed slider, slide groove III, spring III, gear, rotating shaft I, air inlet, air pump, air pipe, and bottom air duct, the air inlet sealing plate is rotated and opened, allowing the air pump to blow cold air into the bottom air duct. This ensures that the bottom of the carrier plate is in continuous contact with the cold air, thus preventing the cold air from blowing directly from the top of the carrier plate and affecting the laser cutting process, making the carrier plate processing process more stable.

[0010] According to the above technical solution, the outer side of the air inlet sealing plate contacts the inner side of the air inlet, and the air inlet, air pump and bottom air duct are internally connected.

[0011] According to the above technical solution, the movement trajectory length of the movable block is consistent with the effective meshing length of the rack, and the front and rear top sides of the fixed platform are equipped with dust collection components.

[0012] According to the above technical solution, the vacuuming assembly includes an L-shaped trigger plate three, a fixed plate, a rotating shaft two, a torsion spring, a cam, a movable plate, a vacuum port, a ventilation pipe, and a vacuum pump chamber. The top of the trigger plate is fixedly connected to the L-shaped trigger plate three. Multiple fixed plates are fixedly connected to the top of the front and rear sides of the fixed platform. A rotating shaft two is rotatably connected between every two fixed plates. A torsion spring is fixedly connected to the connection between the rotating shaft two and the right fixed plate. A cam is fixedly connected to the right side of the rotating shaft two. A movable plate is fixedly connected to the outer side of the rotating shaft two. A vacuum port is fixedly connected to the end of the movable plate near the center of the fixed platform. A vacuum pump chamber is fixedly connected to the top center of the fixed platform. A ventilation pipe is fixedly connected between the vacuum pump chamber and the rear side of the vacuum port. The dust collection component is installed so that when the equipment is cutting, a lot of harmful exhaust gas and flying debris will be generated after the carrier plate is cut. At this time, in conjunction with the L-shaped trigger plate three, fixed plate, rotating shaft two, torsion spring and cam, the movable plate is rotated from the horizontal state to the vertical state. The dust collection pump chamber is activated to absorb the exhaust gas and flying debris by the dust collection port, thereby protecting the safety of the operator.

[0013] According to the above technical solution, the movement trajectory of the dust suction port and the movable plate does not contact the movement trajectory of the movable laser cutting head, and the movement trajectory of the L-shaped trigger plate three contacts the outer side of the cam.

[0014] According to the above technical solution, the dust pump compartment is equipped with a dust pump and a dust collection chamber.

[0015] The advantages of this application are: (1) When the conveyor belt equipment moves the fixed platform to the center of the equipment shell, the electric push rod, trigger plate, slider, slide groove one, L-shaped trigger plate one, triangular slider, and slide groove two work together to make the positioning plate one contact the front side of the carrier plate first, so that the Y-axis position of the carrier plate is fixed. At the same time, the positioning plate two moves to the right, so that the X-axis position of the carrier plate is fixed. Thus, the carrier plate is always close to the inner edge inside the fixed platform, so that the carrier plate is automatically positioned and fixed before cutting, thereby saving manpower, making the positioning of the cutting equipment more convenient, and improving the continuous operation efficiency of the equipment.

[0016] (2) When the carrier plate is being cut, a large amount of heat will accumulate inside the carrier plate. At this time, deformation and damage to the internal circuit are likely to occur. In conjunction with the L-shaped trigger plate II, movable block, rack, fixed slider, slide groove III, spring III, gear, rotating shaft I, air inlet, air pump, air pipe and bottom air channel, the air inlet sealing plate is rotated and opened, so that the air pump blows cold air into the bottom air channel, so that the bottom of the carrier plate is in continuous contact with the cold air, thereby avoiding the cold air blowing directly on the top of the carrier plate and affecting the laser cutting process, making the carrier plate processing process more stable.

[0017] (3) During the cutting process, the equipment of this application will generate a lot of harmful exhaust gas and flying debris after the carrier plate is cut. At this time, the L-shaped trigger plate three, the fixed plate, the rotating shaft two, the torsion spring and the cam will be used to rotate the movable plate from the horizontal state to the vertical state. The dust pump chamber will be started to absorb the exhaust gas and flying debris by the dust suction port, thereby protecting the safety of the operator. Attached Figure Description

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, as Figures 1-4 As shown, a precision carrier plate processing cutting device includes a support frame 1, an equipment housing 2 is fixedly connected to the top center of the support frame 1, a conveyor belt device 3 is mounted on the top of the support frame 1, a Y-axis mobile device 4 is mounted inside the equipment housing 2, an X-axis mobile device 5 is mounted inside the Y-axis mobile device 4, a movable laser cutting head 6 is mounted on the outside of the X-axis mobile device 5, a fixed platform 7 is placed on the top of the conveyor belt device 3, and a maintenance door 8 is hinged to the top of the equipment housing 2. Electric push rods 91 are fixedly connected to the front and rear sides of the inner side of the equipment housing 2. Multiple sliding grooves 95 are formed on the inner surface of the fixed platform 7. These grooves allow sliders 93 to move along their respective directions. A slider 93 is slidably connected inside each groove 95. A trigger plate 92 is fixedly connected to the end of every two sliders 93 furthest from the center of the fixed platform 7. A spring 94 is fixedly connected between the trigger plate 92 and the outer surface of the fixed platform 7. The spring 94 allows the slider 93 to automatically reset when the trigger plate 92 separates from the electric push rod 91. A positioning plate 96 is fixedly connected to the top of the end of each slider 93 closest to the center of the fixed platform 7. The positioning plate 96 contacts the front side of the carrier plate first, fixing the Y-axis position of the carrier plate. A limit slider 97 is fixedly connected to the front surface of the positioning plate 96. Multiple pressure sensors 98 are fixedly connected to the front surface of the positioning plate 96, allowing the pressure sensors 98 to detect the position of the positioning plate 93. 6. Ensure the device is securely fixed in place to prevent excessive movement of the electric push rod 91 that could damage the carrier plate. An L-shaped trigger plate 99 is fixedly connected to the left side of the trigger plate 92. A sliding groove 911 is provided inside the left side of the fixed platform 7. The sliding groove 911 allows the triangular slider 910 to move along the direction of the sliding groove 911. The triangular slider 910 is slidably connected inside the sliding groove 911. A positioning plate 912 is fixedly connected to the top of the end of the triangular slider 910 near the center of the fixed platform 7. The positioning plate 912 moves to the right, fixing the position of the carrier plate in the X-axis direction. This ensures that the carrier plate is always close to the inner edge inside the fixed platform 7, automatically positioning and fixing the carrier plate before cutting. This saves manpower, makes positioning the cutting equipment more convenient, and improves the continuous operation efficiency of the equipment. A spring 913 is fixedly connected between the positioning plate 912 and the inner wall surface of the fixed platform 7. The spring 913 allows the positioning plate 912 to automatically reset after the cutting process is completed.

[0022] A precision carrier plate is placed inside the fixed platform 7. A guide groove is formed on the front surface of the precision carrier plate, and the inside of the guide groove is slidably connected to the outside of the limiting slider 97. The height of the first positioning plate 96 is greater than the thickness of the precision carrier plate, and the movement trajectory of the first positioning plate 96 does not contact the movement trajectory of the second positioning plate 912. Elastic buffer pads are fixedly connected to the outside of the first positioning plate 96 and the second positioning plate 912. A bottom heat dissipation assembly 10 is installed inside the fixed platform 7.

[0023] In practical use, the aforementioned equipment is operated by placing the carrier plate directly inside the fixed platform 7. The conveyor belt 3 is then activated, moving the fixed platform 7 to the center of the equipment casing 2. At this point, the electric push rod 91 is activated, moving outwards and pushing the trigger plate 92 inwards. The trigger plate 92 then moves the slider 93 inwards along the slide groove 95, compressing the spring 94. This causes the slider 93 to move the positioning plate 96 inwards, bringing the carrier plate inwards. The outer side of the limiting slider 97 contacts and limits the movement of the carrier plate, causing the rear side of the carrier plate to abut against the inner wall of the fixed platform 7. The Y-axis position of the carrier plate is fixed, and the trigger plate 92 drives the L-shaped trigger plate 99 to move inward. The L-shaped trigger plate 99 drives the triangular slider 910 to move inward along the slide groove 911. The triangular slider 910 drives the positioning plate 912 to move inward, and the positioning plate 912 drives the carrier plate to move to the right. The right side of the carrier plate abuts against the inner wall of the fixed platform 7, thereby fixing the X-axis position of the carrier plate. This ensures that the carrier plate is always close to the inner edge inside the fixed platform 7, automatically positioning and fixing the carrier plate before cutting. This saves manpower, makes positioning of the cutting equipment more convenient, and improves the continuous operation efficiency of the equipment.

[0024] Example 2, as Figures 2-7As shown, based on Embodiment 1, the bottom heat dissipation assembly 10 includes an L-shaped trigger plate 2 101, a movable block 102, a rack 103, a fixed slider 104, a slide groove 3 105, a spring 3 106, a gear 107, a rotating shaft 108, an air inlet sealing plate 109, an air inlet vent 1010, an air inlet pump 1011, an air inlet pipe 1012, and a bottom air duct 1013. The L-shaped trigger plate 2 101 is fixedly connected to the right side of the trigger plate 92, and a fixed slider is fixedly connected to the right side surface of the fixed platform 7. Block 104 has a movable block 102 slidably connected to the outer side of the fixed slider 104. The top of the movable block 102 has a groove 105, which allows the movable block 102 to move along the groove 105. The outer side of the fixed slider 104 is slidably connected to the inside of the groove 105. A spring 106 is fixedly connected between the left side of the fixed slider 104 and the top left side of the movable block 102, allowing the movable block 102 to automatically return to its original position. The bottom of the movable block 102 is fixedly connected to a rack 103. A bottom air duct 1013 is formed on the inner bottom surface of the fixed platform 7. The bottom air duct 1013 allows the air pump 1011 to blow cold air into it, ensuring continuous contact between the bottom of the carrier plate and the cold air. This prevents the cold air from blowing directly from the top of the carrier plate and affecting the laser cutting process, making the carrier plate processing more stable. An air inlet 1010 is fixedly connected to the right side of the fixed platform 7, and the interior of the air inlet 1010 extends through... Furthermore, a rotating shaft 108 is rotatably connected, and a gear 107 is fixedly connected to the bottom of the rotating shaft 108. The rack 103 meshes with the gear 107. An air inlet blocking plate 109 is fixedly connected to the outer side of the rotating shaft 108. The air inlet blocking plate 109 is set so that it can be rotated open, allowing the air inlet pump 1011 to blow cold air into the bottom air duct 1013. An air inlet pump 1011 is fixedly connected to the right side of the air inlet vent 1010, and an air inlet pipe 1012 is fixedly connected to the top of the air inlet pump 1011.

[0025] The outer side of the air inlet sealing plate 109 contacts the inner side of the air inlet 1010, and the air inlet 1010, the air pump 1011, and the bottom air duct 1013 are connected internally. The length of the movement trajectory of the movable block 102 is consistent with the effective engagement length of the rack 103, and the front and rear top sides of the fixed platform 7 are equipped with dust collection components 11.

[0026] When the above-mentioned equipment is in use, a large amount of heat will accumulate inside the carrier plate during cutting. At this time, deformation and damage to the internal circuitry are likely to occur. The trigger plate 92 moves inward, causing the L-shaped trigger plate 101 to move inward, so that the L-shaped trigger plate 101 contacts the movable block 102. The movable block 102 moves inward along the slide groove 105, stretching the spring 106. The movable block 102 drives the rack 103 to move inward, causing the gear 107 to rotate. The gear 107 drives the rotating shaft 108 to rotate, causing the rotating shaft 108 to rotate and open the air inlet sealing plate 109. At this time, the air inlet pump 1011 is started, allowing cold air to enter the air inlet vent 1010 from the air inlet pipe 1012. The cold air then enters the bottom air duct 1013 from the air inlet vent 1010, so that the bottom of the carrier plate is continuously in contact with the cold air. This avoids the cold air blowing directly from the top of the carrier plate, which would affect the laser cutting process and make the carrier plate processing process more stable.

[0027] Example 3, as Figures 2-8 As shown, based on Embodiment 1, the vacuum assembly 11 includes an L-shaped trigger plate 111, a fixed plate 112, a rotating shaft 113, a torsion spring 114, a cam 115, a movable plate 116, a vacuum port 117, a ventilation pipe 118, and a vacuum pump chamber 119. The top of the trigger plate 92 is fixedly connected to the L-shaped trigger plate 111. Multiple fixed plates 112 are fixedly connected to the top of the front and rear sides of the fixed platform 7. A rotating shaft 113 is rotatably connected between every two fixed plates 112. A torsion spring 114 is fixedly connected to the connection between the rotating shaft 113 and the right fixed plate 112. The torsion spring 114 is provided so that the rotating shaft 113 can automatically... Rotate to reset. A cam 115 is fixedly connected to the right side of the rotating shaft 113. A movable plate 116 is fixedly connected to the outer side of the rotating shaft 113. A dust suction port 117 is fixedly connected to one end of the movable plate 116 near the center of the fixed platform 7. The dust suction port 117 is set so that the movable plate 116 can rotate from a horizontal state to a vertical state. The dust suction pump chamber 119 is activated to absorb the exhaust gas and flying dust by the dust suction port 117, thereby protecting the safety of the operator. The dust suction pump chamber 119 is fixedly connected to the top center of the fixed platform 7. A ventilation pipe 118 is fixedly connected between the dust suction pump chamber 119 and the rear side of the dust suction port 117. The ventilation pipe 118 is a temperature-resistant corrugated hose.

[0028] The movement trajectories of the suction port 117 and the movable plate 116 do not contact the movement trajectory of the movable laser cutting head 6, while the movement trajectory of the L-shaped trigger plate 111 contacts the outer side of the cam 115. The suction pump compartment 119 is equipped with a suction pump and a suction chamber.

[0029] In practical use, when the trigger plate 92 moves inward, it causes the L-shaped trigger plate 111 to move inward, making the L-shaped trigger plate 111 contact the outer side of the cam 115, causing the cam 115 to rotate. The cam 115 then drives the rotating shaft 113 to rotate, causing the torsion spring 114 to store force. This causes the rotating shaft 113 to drive the movable plate 116 to rotate from a horizontal state to a vertical state, so that the dust suction port 117 is directly facing the fixed platform 7. At this time, the dust suction pump chamber 119 is activated, allowing the dust suction port 117 to absorb exhaust gas and flying debris, thereby protecting the safety of the operator.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
