Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to an automated welding equipment and method for tubular quartz products. Background Technology

[0002] In modern quartz tube production, the frame structure of the quartz tube usually needs to be welded. The common welding method requires manual operation on an operating table. However, since quartz tubes are relatively long, welding is required both inside and outside the tube to ensure structural stability. Therefore, the operation is very cumbersome and inefficient.

[0003] In response to this situation, there are currently automatic welding equipment for steel pipe weld treatment. Most of these devices are based on the steel pipe welding process and are mostly horizontal. This not only results in a large footprint but also requires constant alignment during welding, leading to low flexibility.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1-9 This invention provides an implementation scheme: In the production process of modern tubular quartz products, the outer frame needs to be welded into shape. However, current welding methods mostly employ manual butt welding, resulting in low operational efficiency and difficulty in controlling welding quality. To solve this problem, current methods utilize tubular welding equipment, primarily horizontal welding, which not only has a complex structure and large footprint but also requires constant alignment during welding, resulting in low flexibility.

[0047] According to the instruction manual Figure 1-9 As can be seen, in order to solve the above problems, this application discloses an automated welding equipment for tubular quartz products, used for welding quartz tubes, including an operating platform 1, a welding operation mechanism 2, a solder supply mechanism 3, and an internal alignment mechanism 4.

[0048] A quartz tube is placed on the operating table 1, and a welding operation mechanism 2 is located on one side of the operating table 1; a solder supply mechanism 3 is located on the welding operation mechanism 2; an inner alignment mechanism 4 is located on one side of the operating table 1, and the inner alignment mechanism 4 is spaced apart from the welding operation mechanism 2; an inner heating component 41 is slidably installed on the inner alignment mechanism 4, and the inner heating component 41 can slide inside the quartz tube. The inner alignment component corresponds to the solder supply mechanism 3 and heats the solder supply mechanism 3.

[0049] The operating platform 1 serves as the supporting foundation for the quartz tube. During welding, the tubular quartz product is first clamped onto the operating platform 1, forming the welding position. The welding operating mechanism 2, located on one side of the operating platform 1, is the actuator for adjusting the welding position. The welding operating mechanism 2 employs a robot with at least five-axis control. Through the adjustment of the welding operating mechanism 2, the solder supply mechanism 3 can be moved to achieve flexible welding actions. Both the welding operating mechanism 2 and the solder supply mechanism 3 are located outside the weld seam to ensure more thorough heating of the welding area and a more complete bond between the welding wire and the weld seam. This application also includes an internal alignment mechanism 4, which has two motion modes: sliding and rotation. By inputting the weld path data into the internal alignment mechanism 4, the internal alignment mechanism 4 has the following two functions: First, the internal alignment mechanism 4 moves synchronously with the welding operation mechanism 2 and the solder supply mechanism 3, playing a guiding and feedback correction role for the welding wire operation mechanism to ensure welding accuracy. Second, the internal heating component 41, during its synchronous movement with the solder supply mechanism 3, heats the inside of the welding wire to ensure that the welding wire is heated more fully, thereby improving the welding efficiency and the welding quality of the weld.

[0050] Specifically, the welding equipment uses an internal alignment mechanism 4 to slide the internal heating component 41 inside the quartz tube, allowing the internal heating component 41 to match the tortuous direction of the weld. In conjunction with the control of the welding operation mechanism 2 on the solder supply mechanism 3, the movement of the welding operation mechanism 2 and the internal alignment mechanism 4 is synchronized, so that the weld and welding wire are heated from the inside and outside at the same time to obtain higher welding efficiency. Through the pre-planned welding path, a precise welding effect is obtained. At the same time, the quartz tube can be erected for welding through the operating table 1, reducing the floor space. Furthermore, by separating the welding operation equipment from the solder supply mechanism 3 and the operating table 1, the equipment is more dispersed, improving the convenience of equipment layout.

[0051] In some embodiments of this application, the welding operation mechanism 2 and the inner alignment mechanism 4 are spaced apart from the operating table 1. To facilitate welding operations, an operating table 5 is planned in the workshop, and the welding operation mechanism 2, the inner alignment mechanism 4 and the operating table 1 are integrated on the operating table 5. The operating table 5 serves as the working area. A solder container and an electrical box 6 are also integrated on the operating table 5. The solder container is used to hold solder, and the solder is preferably welding wire. The welding wire is inserted into the solder supply mechanism 3 to continuously provide raw materials for welding. The electrical box 6 distributes and controls the electrical energy of the welding operation mechanism 2, the welding supply mechanism and the inner alignment mechanism 4.

[0052] In some embodiments of this application, the internal alignment mechanism 4 includes an internal alignment bracket 42, a sliding member 43, a support member 44, and a rotating member 45; the internal alignment bracket 42 is spaced apart on one side of the operating table 1, the sliding member 43 is slidably disposed on the internal alignment bracket 42, the support member 44 is connected to the sliding member 43, the rotating member 45 is disposed on the support member 44, and the internal heating component 41 is rotatably connected to the rotating member 45; wherein, the internal heating component 41 is disposed relative to the operating table 1.

[0053] The inner alignment bracket 42 serves as the installation and support base for the inner alignment mechanism 4. The inner alignment bracket 42 can slide in conjunction with the sliding member 43. The sliding member 43 drives the support member 44 to move, thereby enabling the support member 44 to slide relative to the quartz tube. The support member 44 then drives the rotating member 45 to slide. The rotating member 45 is connected to the inner heating component 41. Through the action of the sliding member 43, the inner heating component 41 can slide relative to the quartz tube in the length direction. The rotating member 45 can drive the inner heating component 41 to rotate, thereby adjusting the distance between the inner heating component 41 and the inner wall of the quartz tube, i.e., the weld, and thus adjusting the heating effect. At the same time, the rotating member 45 can adjust the radial position of the inner heating component 41 inside the quartz tube, making it easier to correspond to the tortuous changes of the weld, thereby more flexibly guiding the synchronous movement of the welding wire supply mechanism.

[0054] In some embodiments of this application, the rotating component 45 includes a rotating part 451, a connecting part 452, and a driving part 453; a rotating groove is provided on the support frame, the rotating part 451 is rotatably mounted in the rotating groove, the driving part 453 is provided on the support frame and connected to the rotating part 451, and the connecting part 452 connects the rotating part 451 and the internal heating component 41.

[0055] Among them, the rotating part 45 uses the rotating groove as the movable limiting support base, the rotating part 451 can rotate with the rotating groove, the driving part 453 provides power to the rotating part 451, driving the rotating part 451 to drive the connecting part 452 to rotate, the connecting part 452 connects to the inner heating component 41 to facilitate the disassembly and assembly of the inner heating component 41, the rotation of the rotating part 451 causes the connecting part 452 to drive the inner heating component 41 to move circumferentially along the quartz tube, the flexible movement of the inner heating component 41 with the weld seam provides heating to the corresponding side of the welding wire.

[0056] It should be noted that the rotating part 451 can adopt a disc structure design, and the connecting part 452 and the rotating part 451 are slidably connected on the disc diameter to adjust the relative distance between the inner heating component 41 and the inner wall of the quartz tube, i.e. the weld seam, and can also be matched for welding quartz tubes of different diameters.

[0057] In some embodiments of this application, the internal heating assembly 41 includes an internal weld 411, a docking part 412, and a guide 413; the internal weld 411 is connected to the docking part 412, the docking part 412 is detachably connected to the connecting part 452, the guide 413 is connected to the internal weld 411, the guide 413 corresponds to the solder supply mechanism 3, and the welding operation mechanism 2 can control the solder supply mechanism 3 to move with the guide 413.

[0058] The docking part 412 serves as the mounting base for the inner welded part 411. It is connected to the connecting part 452 to install the inner welded part 411 on the rotating part 45. The movement of the rotating part 45 drives the inner welded part 411 to rotate, corresponding to different radial positions of the quartz tube. In conjunction with the movement of the sliding part 43, the inner welded part 411 slides linearly to correspond to the direction of the weld and maintains a stable distance from the weld position of the quartz tube. Furthermore, a guide 413 is provided at the end of the inner heating tube. Through the correspondence between the guide 413 and the solder supply mechanism 3, the movement of the solder supply mechanism 3 is guided, thereby achieving simultaneous heating of the inside and outside of the weld of the quartz tube to improve welding efficiency.

[0059] In some embodiments of this application, the solder supply mechanism 3 includes a fixed frame 31, a solder pass-through 32, a traveler 33, and an outer welding component 34; the fixed frame 31 is connected to the welding operation mechanism 2, the solder pass-through 32 is disposed on the fixed frame 31, the traveler 33 is disposed on the solder pass-through 32, and the outer welding component 34 is mounted on the fixed frame 31; the solder pass-through 32 has a through wire feeding hole, the wire feeding hole has a first end and a second end, the welding wire is passed through the wire feeding hole, and the traveler 33 is mounted on the outer welding component 34 corresponding to the second end of the solder pass-through 32.

[0060] The fixing frame 31 and the welding operation mechanism 2 can be connected separately. The solder feeder 32 is installed on the fixing frame 31. The solder feeder 32 is for the welding wire to pass through. Specifically, the welding wire passes through the wire feeding hole, enters from the first end and exits from the second end to guide and limit the welding wire, ensuring a stable supply of welding wire. A traveler 33 is connected to the solder feeder 32 to control the movement of the welding wire and control the feed amount of the welding wire. After the welding wire is fed into the weld, the welding wire is welded to the weld by the action of the outer welding component 34.

[0061] In some embodiments of this application, the traveler 33 includes a power unit 331, a transmission unit 332, and a traveler 333. The power unit 331 is installed at the first end of the solder pass-through device 32. The power unit 331 is connected to the transmission unit 332, and the transmission unit 332 is connected to the traveler 333. The power provided by the power unit 331 drives the transmission unit 332 to operate. The transmission unit 332 is composed of a multi-stage gear set. The torque of the power unit 331 is amplified by the transmission of the multi-stage gears, and the rotation angle is further indexed so that the transmission unit 332 drives the traveler 333 to move. The traveler 333 abuts against the welding wire. Under the transmission of the traveler 333, the welding wire moves in the wire feeding hole to feed the welding wire out to the second end, so that welding is performed by the outer welding part 34 on one side of the second end.

[0062] It should be noted that the traveling part 333 of the traveler 33 is a roller with diagonal grooves. Under the meshing action of the gears in the transmission part 332, the diagonal grooves of the traveler 33 come into contact with the surface of the solder, thereby causing the welding wire to move along the feeding hole of the solder passer 32. At the same time, in order to ensure that the roller of the traveling part 333 makes sufficient contact with the welding wire, an elastic and slidable abutment wheel 334 is provided on the corresponding side of the traveling part 333.

[0063] In some embodiments of this application, the solder supply mechanism 3 further includes a follower 35, which is disposed opposite to the guide 413. The follower 35 is located outside the quartz tube and is used to guide the movement of the solder wire operating mechanism.

[0064] In order for the solder supply mechanism 3 to move synchronously with the guide 413, the follower 35 is installed on the solder passer 32 and corresponds to the direction of the welding wire passing out. The guide 413 and the follower 35 are magnetically guided. During the movement of the guide 413 along the weld seam, the guide 413 releases a magnetic signal, and the follower 35 captures the magnetic signal and converts it into a control signal. The welding operation mechanism 2 controls the follower 35 to move synchronously with the guide 413, thereby realizing the movement guidance of the welding wire operation mechanism.

[0065] In some embodiments of this application, the guide 413 includes: a mounting part 4131 and a guiding part 4132; the mounting part 4131 is detachably connected to the inner welding part 411, the guiding part 4132 is disposed on the mounting part 4131, and the guiding part 4132 may be a magnetic block or an electromagnetic coil. When an electromagnetic coil is used, the guiding part 4132 generates a magnetic field in a set direction by passing a current with a set direction and power. The follower 35 obtains a unique electromagnetic signal by being in a specific position in the magnetic field. The coordinate system is arranged with the magnetic field. The follower 35 obtains position information by detecting the strength and direction of the magnetic field, and converts the magnetic flux signal into a control signal to control the welding operation mechanism 2 to drive the solder supply mechanism 3 to move, keeping the follower 35 always in the set position of the magnetic field to ensure the accuracy of the welding direction.

[0066] In some embodiments of this application, the follower 35 includes a detection element 351 and a conversion element 352. The detection element 351 is mounted on the mounting bracket 31, and the conversion element 352 is connected to the detection element 351. The detection element 351 can be a magnetic flux detector, and the conversion element 352 is a control chip that can convert magnetic flux signals into electrical signals. The magnetic field of the guide 413 is detected by the detection element 351, and the position of the follower 35 is determined by determining the position of the detection element 351 within the magnetic field. It should be noted that the number of detection elements 351 is specifically at least two, and multiple detection elements are used to determine the position of the follower 35. The measuring element 351 is located in different positions, and the set magnetic flux of several measuring elements 351 is different. By cross-verifying the magnetic flux of multiple measuring elements 351, the spatial gradient of the magnetic field is detected to obtain the position information of the fixed frame 31 with the measuring element 351 in the magnetic field. When the guide 413 drives the coil that generates the magnetic field to move, the fixed frame 31 is kept in the same position in the magnetic field. This enables the follower 35 to guide the welding operation mechanism 2 to move, keeping the follower 35 and the guide 413 moving synchronously, thereby driving the solder supply mechanism 3 to move synchronously to achieve the corresponding welding inside and outside.

[0067] In some embodiments of this application, the welding operation mechanism 2 includes a base 21, a robotic arm 22, and an operating component 23; the base 21 is located on one side of the operating table 1, the robotic arm 22 is mounted on the base 21, and the operating component 23 is connected to the fixing frame 31.

[0068] The base 21 is set on the operating table 5. The base 21 can be separated from the operating table 5 for easy maintenance and position adjustment. A robotic arm 22 is connected to the base 21. The robotic arm 22 can perform at least five-axis motion. The movement of the robotic arm 22 can drive the operating component 23 to move flexibly. The operating component 23 is connected to the fixed frame 31, so it can drive the welding material supply mechanism 3 to move synchronously. This allows the operating component 23 to follow the movement of the internal heating component 41, realizing the operation of synchronously aligning the weld seam inside and outside for welding processing, thereby improving welding efficiency and welding quality.

[0069] In some embodiments of this application, the operating platform 1 includes a support base 11, a steering base 12, and a clamping assembly 13; the support base 11 is disposed on one side of the base 21, the steering base 12 is rotatably mounted on the support base 11, and the clamping assembly 13 is mounted on the steering base 12 for clamping the quartz tube.

[0070] The operating platform 1 is supported and installed on the support base 11. The support base 11 is detachably connected to the operating table surface 5 to support the steering seat 12. The steering seat 12 can adjust the orientation of the clamping assembly 13 by rotating on the support base 11. The clamping assembly 13 clamps the quartz tube to position it. The orientation of the quartz tube can be adjusted by the steering seat 12 to form the basic position for welding operations. It should be noted that the steering seat 12 has a working plane. The clamping assembly is set on the working plane. The axis of the working plane is perpendicular to the horizontal during operation so that the quartz tube is perpendicular to the horizontal. During clamping, the axis of the working plane of the steering seat 12 can be parallel to the horizontal to facilitate the installation of the quartz tube.

[0071] In some embodiments of this application, the clamping assembly 13 includes a controller 131, a plurality of grippers 132, and a plurality of contact portions 133. The controller 131 is disposed on the steering seat 12, and the plurality of grippers 132 are slidably mounted on the working plane. The controller 131 is connected to the plurality of grippers 132 in a transmission manner. The controller 131 can synchronously control the sliding of the plurality of grippers 132. The plurality of grippers 132 synchronously contact the outer wall of the quartz tube to clamp the quartz tube and achieve centering clamping of the quartz tube. The plurality of contact portions 133 are mounted on the plurality of grippers 132 and abut against the outer wall of the quartz tube to achieve protection of the quartz tube.

[0072] It should be noted that when the quartz tube is clamped, the weld should face the welding operation mechanism 2, and after it is clamped and erected, the position of the guide 413 should be adjusted so that the guide 413 initially corresponds to the position of the weld.

[0073] In summary, the automated welding equipment for tubular quartz products has the following advantages: the internal alignment mechanism 4 allows the internal heating component 41 to slide inside the quartz tube, enabling it to match the tortuous direction of the weld seam. Combined with the control of the welding operation mechanism 2 on the solder supply mechanism 3, the movements of the welding operation mechanism 2 and the internal alignment mechanism 4 are synchronized, allowing for simultaneous heating of the weld seam and welding wire from both inside and outside, resulting in higher welding efficiency. Furthermore, the pre-planned welding path ensures precise welding results. The operating platform 1 allows the quartz tube to be erected for welding, reducing the floor space required. The separation of the welding operation equipment from the solder supply mechanism 3 and the operating platform 1 further disperses the equipment, improving the convenience of equipment layout.

[0074] In other embodiments of this application, in order to adapt to the use of the above-mentioned automated welding equipment for tubular quartz products, this application also discloses an automated welding method for tubular quartz products, used to operate the above-mentioned equipment to improve welding efficiency and welding quality. Specifically, the method includes the following steps:

[0075] Step S100: Quartz tube clamping and initial positioning, clamp the quartz tube onto the operating table.

[0076] Step S110: Check the connection stability between the support base and the operating table, confirm that the steering base can rotate freely and the working plane is horizontal, and clean the surface of the clamping components to prevent scratches on the quartz tube.

[0077] Step S120: Place the quartz tube to be welded horizontally on the working plane of the steering seat, drive multiple grippers to slide synchronously through the controller, so that the contact part makes uniform contact with the outer wall of the quartz tube to achieve automatic centering and clamping, and adjust the weld seam to face the direction of the welding operation mechanism.

[0078] Step S130: Rotate the steering seat to make the working plane perpendicular to the horizontal. Confirm that the initial position of the weld is on the same side as the guide of the inner alignment mechanism and the follower of the solder supply mechanism by using the positioning marks on the operating table or by using a laser calibrator.

[0079] Step S200: Initialize the internal alignment mechanism to align the internal heating component with the weld position of the quartz tube, and plan the welding line based on the weld data or visual inspection structure.

[0080] Step S210: Move the sliding member along the inner alignment bracket so that the support member drives the rotating member and the inner heating component into the quartz tube to a preset depth. Adjust the disc diameter position of the rotating part through the rotating groove to ensure that the end of the inner welding part maintains a safe distance of at least 2mm from the inner wall of the weld.

[0081] Step S220: Start the drive unit to drive the rotating part to rotate, adjust the radial position of the inner heating component through the connecting part, so that the mounting part of the guide is tightly connected to the inner welded part, and adjust the current direction and power of the guide part (such as an electromagnetic coil) to generate a reference magnetic field.

[0082] Step S230: Pair the guide and follower. Install the detection component of the follower on the fixed frame of the solder supply mechanism. Convert the detected magnetic field signal into an electrical signal through the conversion component. Control the welding operation mechanism to initially adjust the position of the robotic arm to achieve magnetic guidance pairing of the guide and follower.

[0083] Step S240: Input the various dimensional data of the quartz tube (diameter, length, and weld travel path) into the control chip of the sliding and rotating parts of the inner alignment mechanism, and plan the welding path according to the initial position of the guide corresponding to the initial starting point of the weld.

[0084] Step S300: Configure the solder supply mechanism so that the welding wire is in the synchronous position with the internal heating element, and perform welding wire pretreatment.

[0085] Step S310: Wire loading and path calibration. The wire is fed into the wire feeding hole from the first end of the wire feeder. The power unit of the feeder drives the transmission unit to rotate. The elastic abutment wheel ensures that the wire is smoothly fed in. The length of the wire extending from the second end is adjusted to 5-10mm.

[0086] Step S320: Preheating preparation of the external welding part. Start the heating module of the external welding part to the preset temperature. Control the wire feeding speed through the traveler to ensure stable contact between the end of the welding wire and the heating area of ​​the external welding part.

[0087] Step S330: The magnetic field spatial gradient is cross-verified by multiple detection devices. The electromagnetic signal detected by the detection devices is converted into a control signal. The magnetic field spatial gradient is used for positioning so that the follower is always in the magnetic field set position, ensuring that the welding operation mechanism drives the solder supply mechanism to maintain a synchronous trajectory with the internal heating component.

[0088] Step S400: Automatic welding of the weld seam is performed. The welding operation mechanism is guided by the inner alignment mechanism to control the welding material supply mechanism to move along the weld seam, and the inner and outer welding parts are used to weld the quartz tube simultaneously.

[0089] Step S410: Robotic arm motion control. The five-axis robotic arm of the welding operation mechanism adjusts the position of the operating component according to the magnetic field signal of the guide, driving the fixed frame and the welding material supply mechanism to move along the weld seam. At the same time, the sliding and rotating components of the inner alignment mechanism move in coordination to maintain a stable distance between the inner heating component and the inner wall of the weld seam.

[0090] Step S420: Simultaneous internal and external heating welding. The internal heating component heats the inside of the weld seam through the internal welding component, and the external welding component heats the outside of the weld seam. The moving part continuously supplies welding wire. Under the combined action of the internal and external heat sources, the welding wire and the weld seam are fully fused together to form a uniform weld seam.

[0091] Step S430: Real-time quality monitoring. The control system of the electrical box monitors parameters such as welding temperature, wire feed speed, and robotic arm movement trajectory. It can be combined with vision sensors or infrared detectors to provide real-time feedback on weld formation quality and dynamically adjust welding parameters to ensure welding quality.

[0092] Step S500: After welding is completed, reset the equipment and remove the welded quartz tube.

[0093] Step S510: After welding is completed, turn off the power and keep the robotic arm in position until the weld cools to a safe temperature. Check the appearance quality and sealing of the weld by manual or automatic inspection device.

[0094] Step S520: Slide the internal heating component out of the quartz tube, and reset the sliding and rotating parts to their initial positions; clean the solder wire residue in the solder supply mechanism, and turn off the power to the electrical box; disassemble the quartz tube and clean the surface of the operating table.

[0095] Step S530: Maintenance and Recording: Perform routine maintenance on the equipment and record the welding parameters such as temperature, speed, trajectory, and quality inspection results to provide data reference for subsequent production.

[0096] The implementation method using the above-mentioned equipment achieves vertical welding by erecting the quartz tube on the operating platform, reducing the floor space required; the internal alignment mechanism slides to match the tortuous direction of the weld seam, and the welding operation mechanism synchronously controls the solder supply mechanism to achieve synchronous heating inside and outside, improving welding efficiency; advance path planning ensures welding accuracy; modular and separate equipment layout improves site adaptability and collaboratively solves the problems of low manual efficiency and unstable quality.
