Description

Technical Field

[0001] The present invention relates to the technical field of control cabinets, and particularly to an adjustable laser welding device and a laser welding method for medical door production. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a laser beam with a high energy density as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology;

[0003] An adjustable laser welding device for medical door production described in the patent application with the publication number CN215145695U includes a welding table and a welding head. A welding head is provided on the top of the welding table. A blanking device is provided on the top of the welding table. A first slot is penetrated through the top of the welding table. A second slot is opened in the middle of the top end of the welding table. An aggregate device is provided on the left end of the welding table. An adjusting device is provided at the rear end of the welding table;

[0004] When a laser welding machine welds a metal plate, the temperature in the factory building in the low-lying and northerly areas is relatively low. When the metal plate is welded at a low temperature, since the melting speed of the metal becomes slower and the laser energy cannot fully act on the metal, the penetration depth of the weld seam decreases. And the decrease in the penetration depth may cause the strength and toughness of the weld seam to decrease, thereby affecting the overall performance of the welded part. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an adjustable laser welding device and a laser welding method for medical door production, achieving the purpose of solving the above problems.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: An adjustable laser welding device for medical door production includes a bottom plate. A first sliding rod is fixedly connected to the top of the bottom plate. A first sliding machine is provided on the outer wall of the first sliding rod. A second sliding rod is fixedly connected to the outer wall of the first sliding machine. A second sliding machine is provided on the outer wall of the second sliding rod. A laser welder is fixedly connected to the outer wall of the second sliding machine. An electric telescopic rod is provided at the bottom of the laser welder. The output end of the laser welder is electrically connected to the input end of the electric telescopic rod. A laser welding head is fixedly connected to the bottom of the electric telescopic rod.

[0007] The heating mechanism includes:

[0008] A lifting plate. The lifting plate is in a circular plate structure. A fixed sleeve is slidably connected to the inner wall of the lifting plate. The inner wall of the fixed sleeve is fixedly connected to the outer wall of the electric telescopic rod. A threaded bar is fixedly connected to the outer wall of the fixed sleeve. The inner wall of the lifting plate and the outer wall of the threaded bar are slidably connected through a ball. The lifting plate is used to lift on the outer wall of the fixed sleeve;

[0009] A baffle plate, the inner wall of the baffle plate is fixedly connected to the outer wall of the fixed sleeve. The baffle plate is a circular plate-like structure. A push plate is hinged to the bottom of the ascending lifting plate through a hinge rod. A heat conduction block is arranged at the bottom of the push plate, and a heater is arranged on the outer wall of the push plate. The baffle plate is used to limit the ascending position of the lifting plate.

[0010] Preferably, a hinge block is fixedly connected to the bottom of the lifting plate. The inner wall of the hinge block is hinged to one end of the hinge rod, and the other end of the hinge rod is hinged to the top of the push plate through another hinge block. A torsion spring is used to reset the hinge rod.

[0011] Preferably, a torsion spring is arranged at the hinged part of the hinge rod and the inner wall of the hinge block. The two ends of the torsion spring are respectively fixedly connected to one end of the hinge rod and one side of the hinge block.

[0012] Preferably, the top of the push plate is fixedly connected to the bottom of the heater. The heater is electrically connected to the heat conduction block. The heater is used to control the heat conduction block to play a heating role.

[0013] Preferably, a flow guiding mechanism is arranged on the outer wall of the push plate. The flow guiding mechanism includes a groove. The groove is opened on one side of the push plate, and blades are fixedly connected to the inner wall of the groove.

[0014] Preferably, the flow guiding mechanism further includes a stop block. The stop block is fixedly connected to the heater. The bottom of the stop block is fixedly connected to the top of the push plate. The stop block is used to limit the hinge rod.

[0015] Preferably, an energy-saving mechanism is arranged on the outer wall of the heater. The energy-saving mechanism includes an elastic rope. One end of the elastic rope is fixedly connected to a tension sensor. The two sides of the tension sensor are fixedly connected to the outer wall of the stop block through elastic ropes. The tension sensor is electrically connected to the heater. The tension sensor is used to detect the tension values of the two ends of the elastic rope.

[0016] Preferably, the number of the push plates is four. The four push plates are arranged in an equilateral array with the electric telescopic rod as the center. The four push plates can form a disc shape.

[0017] An adjustable laser welding method for medical door production, including the following steps:

[0018] S1: Place the metal plate to be cut on the bottom plate, and then start the first sliding rod to control the second sliding rod to slide back and forth on the first sliding rods on both sides of the bottom plate to adjust the position;

[0019] S2: Meanwhile, the second sliding motor on the second sliding rod drives the laser welder to move left and right on the second sliding rod to adjust the position, thereby driving the electric telescopic rod and the laser welding head below the laser welder to move freely;

[0020] S3: After the laser welding head is aligned with the position of the metal plate to be laser cut, the laser welder automatically controls the electric telescopic rod to extend and descend, driving the laser welding head to descend synchronously to complete the laser cutting work on the metal plate.

[0021] The present invention provides an adjustable laser welding device and a laser welding method for medical door production. It has the following beneficial effects:

[0022] 1. By setting a heating mechanism, the present invention uses the heater that has been turned on in advance to quickly heat the heat conduction block at the bottom of the push plate, so that the heat conduction block maintains a certain temperature. Before the laser welding head descends to laser weld the metal plate, the heat conduction block at the bottom of the push plate is used to preheat the position around the welding point in a contact manner in advance, avoiding the problem that the temperature of the metal plate is relatively low in cold and low-temperature regions, resulting in a slower melting speed of the metal, insufficient laser energy acting on the metal, and a decrease in the penetration depth of the weld.

[0023] 2. By setting a heating mechanism, the present invention drives the heat conduction block to rotate and evenly heat the periphery of the welding area of the metal plate through the rotation of the push plate, further improving the heating speed and the uniformity of heating, and avoiding problems such as uneven heating and slow heating.

[0024] 3. By setting a heating mechanism, while the push plate drives the bottom heat conduction block to rotate and heat, due to the vertical bar shape of the heat conduction block, the stains and particulate matters on the metal plate are centrifugally pushed outwards. The residue particles are thrown outwards through the gaps between each heat conduction block, keeping the area around the welding point clean. Because the residue particles may remain in the weld, resulting in impurities in the weld, thereby reducing the strength, sealing performance, and other quality aspects of the weld.

[0025] 4. By setting a heating mechanism, during welding, the four push plates disperse outwards synchronously, thereby giving the electric telescopic rod and the laser welding head continuous descending space. Finally, the laser welding head lands on the metal plate, and at the same time, the four push plates disperse, avoiding affecting the laser welding at this moment. Before welding, the automatic heating and cleaning of the welding point on the metal plate are completed, but they avoid interfering during laser welding, avoiding problems that affect the laser welding accuracy.

[0026] 5. The present invention sets a flow guide mechanism, and the air flows outward along the metal plate through the gaps between each heat-conducting block. While the particle attachments at the welding point are discharged outward through the heat-conducting block by the air, the air flow is also used to make the heated air automatically flow outward along the metal plate, so as to achieve stable and uniform heat dissipation. After the welding at this point is completed, when it is moved to other welding points, the temperature of the metal plate itself is not so low, which further ensures the stable heating effect of the heat-conducting block in the subsequent welding work.

[0027] 6. The present invention sets a flow guide mechanism. When the hinge rod continues to push the push plate outward, the push plate will tilt up when it continues to be pushed outward, so that the heat-conducting block at the bottom of the push plate is separated from the contact with the metal plate. At this time, the continuous heat supply of the heat-conducting block itself is not absorbed by the metal plate below far away from the welding point, which will cause energy waste and the temperature of the heat-conducting block to be always absorbed. When the area around the welding point is heated subsequently, the problem of insufficient heating will occur, so that each heating work around the welding point can always be kept stable and balanced.

[0028] 7. The present invention sets an energy-saving mechanism and processes it through the central processing unit in the heater. When the tension sensor receives a greater tension, the heater reduces the wattage of the heat-conducting block, thereby reducing unnecessary energy waste when the heat-conducting block is not heated in this state. While ensuring energy consumption and cost savings, it also avoids overheating when the heat-conducting block is not in contact with the metal plate, and subsequent heating of the metal plate will cause overheating.

[0042] Example 1: Please refer to Figures 1-4 , the present invention provides a technical solution: An adjustable laser welding device for medical door production, including a bottom plate 1, a first sliding rod 5 is fixedly connected to the top of the bottom plate 1, a first sliding machine 6 is arranged on the outer wall of the first sliding rod 5, a second sliding rod 7 is fixedly connected to the outer wall of the first sliding machine 6, a second sliding machine 8 is arranged on the outer wall of the second sliding rod 7, a laser welder 9 is fixedly connected to the outer wall of the second sliding machine 8, an electric telescopic rod 10 is arranged at the bottom of the laser welder 9, the output end of the laser welder 9 is electrically connected to the input end of the electric telescopic rod 10, and a laser welding head 11 is fixedly connected to the bottom of the electric telescopic rod 10; an electric telescopic rod 10 is arranged on the outer wall of the heating mechanism 2;

[0043] The heating mechanism 2 includes:

[0044] A lifting plate 202, the lifting plate 202 is a circular plate structure, the inner wall of the lifting plate 202 is slidably connected to a fixed sleeve 201, the inner wall of the fixed sleeve 201 is fixedly connected to the outer wall of the electric telescopic rod 10, a threaded bar 203 is fixedly connected to the outer wall of the fixed sleeve 201, and the inner wall of the lifting plate 202 and the outer wall of the threaded bar 203 are slidably connected by balls. The lifting plate 202 is used to lift on the outer wall of the fixed sleeve 201;

[0045] The baffle 204, the inner wall of the baffle 204 is fixedly connected to the outer wall of the fixed sleeve 201. The baffle 204 is a circular plate-like structure. The bottom of the rising lifting plate 202 is hinged with a push plate 207 through a hinge rod 206. A heat conducting block 209 is arranged at the bottom of the push plate 207, and a warmer 208 is arranged on the outer wall of the push plate 207. The baffle 204 is used to limit the rising position of the lifting plate 202.

[0046] The bottom of the lifting plate 202 is fixedly connected with a hinge block 205. The inner wall of the hinge block 205 is hinged with one end of the hinge rod 206, and the other end of the hinge rod 206 is hinged with the top of the push plate 207 through another hinge block 205. The torsion spring is used to reset the hinge rod 206.

[0047] A torsion spring is arranged at the hinged part of the hinge rod 206 and the inner wall of the hinge block 205. The two ends of the torsion spring are respectively fixedly connected to one end of the hinge rod 206 and one side of the hinge block 205.

[0048] The top of the push plate 207 is fixedly connected to the bottom of the warmer 208. The warmer 208 is electrically connected to the heat conducting block 209. The warmer 208 is used to control the heat conducting block 209 to play a heating role;

[0049] During use, place the metal plate to be cut on the bottom plate 1, then start the first sliding rod 5 to control the second sliding rod 7 to slide back and forth on the first sliding rods 5 on both sides of the bottom plate 1 to adjust the position. At the same time, the second sliding machine 8 on the second sliding rod 7 drives the laser welder 9 to move left and right on the second sliding rod 7 to adjust the position, so as to drive the electric telescopic rod 10 and the laser welding head 11 below the laser welder 9 to move freely. After aligning the laser welding head 11 with the position of the metal plate to be laser cut, the laser welder 9 automatically controls the electric telescopic rod 10 to extend and descend, driving the laser welding head 11 to descend synchronously to complete the laser cutting work of the metal plate;

[0050] During the downward movement before the laser welding head 11 contacts the metal plate, as the electric telescopic rod 10 continues to descend, it will drive the fixed sleeve 201 on the outer wall and the lifting plate 202 to descend synchronously. Since the lifting plate 202 is hinged to the push plate 207 through the hinge rod 206, it also drives the push plate 207 to descend synchronously until the push plate 207 abuts against the metal plate. As the electric telescopic rod 10, the fixed sleeve 201, and the lifting plate 202 continue to descend, the push plate 207 will be pushed to descend through the hinge rod 206. At this time, since there is a torsion spring connection between the hinge block 205 and the hinge rod 206, the descent of the lifting plate 202 will not press the hinge block 205 to rotate, but will instead push the lifting plate 202 itself upward to slide on the outer wall of the fixed sleeve 201 and rotate and slide upward through the sliding connection between the inner wall and the thread bar 203. The inner wall of the lifting plate 202 and the thread bar 203 are connected by ball bearings for sliding, so the friction is small. When the lifting plate 202 rises on the outer wall of the fixed sleeve 201, it rotates and drives the lower hinge rod 206, hinge block 205, and push plate 207 to rotate synchronously. At the same time, the heat conduction block 209 at the bottom of the push plate 207 is quickly heated through the heater 208 that has been turned on in advance, so that the heat conduction block 209 maintains a certain temperature. Before the laser welding head 11 descends to perform laser welding on the metal plate, the heat conduction block 209 at the bottom of the push plate 207 is used to preheat the position around the welding point in a contact manner in advance, avoiding the problem that the temperature of the metal plate is relatively low in cold and low-temperature regions, resulting in a slower melting speed of the metal, insufficient laser energy acting on the metal, and a decrease in the penetration depth of the weld seam;

[0051] Moreover, the rotation of the push plate 207 can drive the heat conduction block 209 to rotate and evenly heat the area around the welding area of the metal plate, further improving the heating speed and uniformity, and avoiding problems such as uneven heating and slow heating;

[0052] As the push plate 207 drives the heat conduction block 209 at the bottom to rotate and heat, the vertical strip shape of the heat conduction block 209 also has the effect of centrifugally pushing out stains and particulate matter on the metal plate. The residue particles are thrown out through the gaps between each heat conduction block 209 to keep the area around the welding point clean, because the residue particles may remain in the weld seam, resulting in impurities in the weld seam, which will reduce the strength, sealing performance, and other quality aspects of the weld seam;

[0053] As the lifting plate 202 slides and rotates on the outer wall of the fixing sleeve 201 and the threaded strip 203, it will abut against the baffle 204. At this moment, the lifting plate 202 cannot continue to rise. At this time, the electric telescopic rod 10 continues to descend, pushing the baffle 204 to bring the lifting plate 202 to continue to descend. At this time, the lifting plate 202 will squeeze the hinge rod 206 between the two hinge blocks 205, so that the torsion spring between the hinge rod 206 and the hinge block 205 begins to rotate and deform, so that the hinge rod 206 is pushed to hinge outward. The push plate 207 is pushed outward by the hinge block 205 below, and the four push plates 207 are dispersed outward synchronously, thereby providing the electric telescopic rod 10 and the laser welding head 11 with continuous descending space. Finally, the laser welding head 11 falls on the metal plate, and the four push plates 207 are dispersed to avoid affecting the laser welding at this moment, so as to realize automatic heating and cleaning of the welding points of the metal plate before welding, but avoid the problem of affecting the laser welding accuracy by themselves during laser welding;

[0054] Example 2: Please refer to Figures 1-11 On the basis of the first embodiment, the present invention provides a technical solution: a guide mechanism 3 is provided on the outer wall of the push plate 207, and the guide mechanism 3 includes a groove 302, the groove 302 is opened on one side of the push plate 207, and a blade 303 is fixedly connected to the inner wall of the groove 302.

[0055] The flow guiding mechanism 3 further includes a stopper 301, the stopper 301 is fixedly connected to the heater 208, the bottom of the stopper 301 is fixedly connected to the top of the push plate 207, and the stopper 301 is used to limit the hinge rod 206;

[0056] When the heat conductive block 209 and the push plate 207 rotate, each push plate 207 has a blade 303 on the groove 302 formed on one side. Therefore, when the push plate 207 rotates, the air above is moved by the rotation of the blade 303, so that the air flows from top to bottom. The air flows outward along the metal plate through the gaps between each heat conductive block 209, and the particle attachments at the welding point are discharged outward through the heat conductive block 209 through the air. At the same time, the temperature of the heat conductive block 209 itself is blown out partly by the air flow, so that the heated air automatically flows outward along the metal plate, and the heat is stably and evenly dissipated outward. After the welding at this point is completed, when it is moved to other welding points, the temperature of the metal plate itself is not so low, which further ensures the stable heating effect of the heat conductive block 209 in the subsequent welding work.

[0057] When the push plate 207 is pushed outward and spread apart by the hinge rod 206 and the hinge block 205, the push plate 207 remains horizontal because the bottom of the push plate 207 always slides against the surface of the metal plate. At this time, the angle between the hinge rod 206 and the push plate 207 becomes smaller, until the hinge rod 206 hits the stopper 301 on the push plate 207 during the pushing process of the push plate 207. At this moment, the hinge rod 206 hits the push plate 207 through the stopper 301, so that the push plate 207 cannot continue to maintain its horizontal movement state, thereby When the hinge rod 206 continues to push the push plate 207 outward, the push plate 207 will tilt up when it is pushed outward, so that the heat conductive block 209 at the bottom of the push plate 207 is out of contact with the metal plate, so that the continuous heat supply of the heat conductive block 209 itself is not absorbed by the metal plate below far away from the welding point, which will cause energy waste and the temperature on the heat conductive block 209 is always absorbed. When the surrounding area of ​​the welding point is heated subsequently, the problem of insufficient heating temperature occurs, so that each heating work around the welding point is always kept stable and balanced;

[0058] Example 3: Please refer to Figures 1-12 Based on the first and second embodiments, the present invention provides a technical solution:

[0059] An energy-saving mechanism 4 is provided on the outer wall of the heater 208, and the energy-saving mechanism 4 includes an elastic rope 401, one end of the elastic rope 401 is fixedly connected to a tension sensor 402, and both sides of the tension sensor 402 are fixedly connected to the outer wall of the block 301 through the elastic rope 401, and the tension sensor 402 is electrically connected to the heater 208. The tension sensor 402 is used to detect the tension value of the elastic ropes 401 at both ends.

[0060] There are four push plates 207 , which are arranged in a proportional array with the electric telescopic rod 10 as the center. The four push plates 207 can form a disc shape.

[0061] When the push plates 207 are pushed open, each push plate 207 will move away from each other. At this time, the elastic ropes 401 between each heater 208 will be pulled because they move away from each other. The elastic ropes 401 have elastic force, and a tension sensor 402 is connected in the middle of an elastic rope 401. Therefore, the tension sensor 402 will bear the tension of the elastic ropes 401 on both sides. Then the tension sensor 402 will automatically identify its tension data and send the data to the heater 208. The central processor in the heater 208 processes it. When the tension sensor 402 receives a greater tension, the heater 208 reduces the wattage of the heat-conducting block 209, thereby reducing the unnecessary energy waste when the heat-conducting block 209 is not heated in this state, ensuring energy consumption and cost savings, and avoiding overheating when the heat-conducting block 209 is not in contact with the metal plate, and the subsequent heating of the metal plate will cause overheating.

[0062] An adjustable laser welding method for medical door production, comprising the following steps:

[0063] S1: Place the metal plate to be cut on the bottom plate 1, and then start the first sliding rod 5 to control the second sliding rod 7 to slide back and forth on the first sliding rods 5 on both sides of the bottom plate 1 to adjust the position.

[0064] S2: At the same time, the second sliding machine 8 on the second sliding rod 7 drives the laser welder 9 to move left and right on the second sliding rod 7 to adjust the position, thereby driving the electric telescopic rod 10 and the laser welding head 11 below the laser welder 9 to move freely.

[0065] S3: After aligning the laser welding head 11 with the position of the metal plate to be laser cut, the laser welder 9 automatically controls the electric telescopic rod 10 to extend and descend, driving the laser welding head 11 to descend synchronously to complete the laser cutting work on the metal plate.

[0066] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
