Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0048] Referring to FIG. 1-13, a welding device for processing quartz base includes a base, an automatic welding device, a supporting device, a clamping device, a transmission device, and a reference plate 10. The base comprises a quartz flange 11, a quartz sheet 12, and a quartz rod 13 connected in one body, and the number of the quartz rod 13 is not less than two. The number of the quartz rod 13 is not less than two, which is vertically welded between two quartz flanges 11 parallel to each other, and is annularly distributed on the surface of the quartz flange 11 with the same angle between adjacent quartz rods 13. The number of the quartz sheet 12 is multiple, and the multiple quartz sheets 12 are parallel and have equal spacing, and the multiple quartz rods 13 jointly support the quartz sheet 12 and make the quartz sheet 12 parallel to the quartz flange 11. The supporting device supports the base and closely adheres to the quartz flange 11, and the supporting device comprises a center base plate 21 at the bottom end of the base and an edge base plate 22, which is rotationally installed on the outer circumferential surface of the center base plate 21 and is concentrically arranged with the center base plate 21. The supporting device is provided with a gap on both sides of the edge base plate 22 and is symmetrical about the center surface of the supporting device, and the gap is located at the welding position, and the center of the gap is connected through the center of the center base plate 21. Two sets of automatic welding devices are respectively placed at the two gap positions and can move towards or away from each other. The two sets of automatic welding devices move towards each other to the gap position to carry out welding work. The clamping device is concentrically arranged with the supporting device and rotates with the center of the supporting device as the center. The clamping device clamps the quartz flange 11 and positions the base, and the clamping device is engaged with the surface of the center base plate 21, and the clamping device, the center base plate 21 and the base move synchronously. The transmission device penetrates through the supporting device and is fixed with the clamping device. The transmission device comprises a horizontal transmission 5, a vertical transmission 7, and an engagement structure 9, the horizontal transmission 5 is used to convey the automatic welding device to the welding position to weld the base, the vertical transmission 7 is used to convey the automatic welding device to different heights to weld the welding points on the surface of different quartz sheets 12, and the engagement structure 9 is used to drive the base to rotate to weld different welding points on the surface of the same quartz sheet 12. The engagement structure 9 is connected with the clamping device and operates synchronously with the clamping device.

[0049] The welding device is provided with two automatic welding devices, which are used to weld the welding points on different end surfaces of the quartz sheet 12. Firstly, two welding points can be welded at the same time, which improves the welding efficiency of the base. Secondly, through the transmission device, different welding points on the same quartz sheet 12 of the base, different welding points at different heights can be welded, which is fully automated, shortens the welding time, reduces the workload of the operator, and improves the welding efficiency of the base.

[0050] The number of the reference plates 10 is two and they are symmetrically arranged about the vertical center of the base, one of the reference plates 10 comprises a transverse reference plate 1001 and a longitudinal reference plate 1002 which are perpendicular to each other, the transverse reference plate 1001 is fixed at the bottom. A plurality of support rods 23 are vertically inserted at the bottom end of the edge base plate 22, the support rods 23 are divided into short rods and long rods, the short rods are inserted into the transverse reference plate 1001, and the long rods are flush with the bottom end of the transverse reference plate 1001, that is, the support device is fixed in position relative to the transverse reference plate 1001 by the short rods.

[0051] The automatic welding device comprises a longitudinal clamping plate 42 which is clamped into the longitudinal reference plate 1002, the longitudinal clamping plate 42 comprises a set of rectangular clamping plates which are arranged inside the longitudinal reference plate 1002 and slide up and down along the longitudinal axis of the longitudinal reference plate 1002, one side of the rectangular clamping plate is welded with a welding gun mounting plate, and the other side is welded with a rectangular spur gear 43, the rectangular spur gear 43, the rectangular clamping plate and the welding gun mounting plate move synchronously.

[0052] The top end of the welding gun mounting plate is rotatably mounted with a rotating plate body 44, and the welding gun mounting plate is provided with an annular groove for clamping the rotating plate body 44. The top end of the rotating plate body 44 is welded with a welding gun 45, wherein the rotating angle of the rotating plate body 44 inside the annular groove is not less than 120 degrees. The position of the welding gun 45 is changed by the rotating plate body 44 rotating in an arc trajectory, and the nozzle position of the welding gun 45 changes accordingly. The flame emitted by the welding gun 45 uniformly melts the contact surface of the quartz sheet 12 and the quartz rod 13 in constant movement, so that the contact surface of the quartz sheet 12 and the quartz rod 13 is uniformly heated, thereby realizing uniform welding and improving the welding effect.

[0053] The rotating plate body 44 comprises a rotating mounting plate 441 which is inserted into the annular groove, an arc gear 442 which is welded to the outer surface of the rotating mounting plate 441, and a mounting ring 443 which is integrally connected to the top end of the rotating mounting plate 441. The welding gun 45 is positioned inside the mounting ring 443 under pressure. The annular groove is used to limit the rotating trajectory of the rotating plate body 44 to ensure that the nozzle of the welding gun 45 is consistent with the shape of the welding point. That is, during the rotation of the welding gun 45, the nozzle forms a circular arc with one end greater than 120 degrees, which is consistent with the shape of the welding point on the surface of the quartz sheet 12. By rotating the nozzle, the welding range of the welding gun 45 is as large as possible, thereby increasing the effective welding area of the welding gun 45 and improving the welding efficiency.

[0054] The top end of the welding gun mounting plate is provided with an angle adjusting member 41 and a position sensor 46 for monitoring the welding point position of the base surface. The angle adjusting member 41 comprises a first motor, a first circular gear at the end of the output shaft of the first motor, and a first motor controller for controlling the rotation, direction and speed of the output shaft of the first motor. The monitoring range of the position sensor 46 is slightly larger than the welding point range of the base, and when all the welding points on the base surface to be welded enter the monitoring range of the position sensor 46, it is determined that the welding points of the base are within the monitoring range of the position sensor 46, triggering the automatic welding device to start welding.

[0055] When the welding point on the base surface to be welded enters the monitoring range of the position sensor 46 but is not completely monitored by the position sensor 46, it is determined that the welding point of the base enters the monitoring range of the position sensor 46, triggering the driving member 24 to rotate, so that the central base plate 21 and the edge base plate 22 rotate concentrically. When the welding point on the base surface does not enter the monitoring range of the position sensor 46, it is determined that the welding point of the base does not enter the monitoring range of the position sensor 46, triggering the engagement structure 9 to work, the horizontal transmission 5 engages with the arc gear 442, the position sensor 46 converts the monitoring result into an electrical signal output, realizes the triggering mechanism, and the angle adjusting member 41, the automatic welding device and the engagement structure 9 receive the electrical signal and are automatically triggered to start working.

[0056] The horizontal transmission 5 is arranged between the two longitudinal reference plates 1002, and the engagement structure 9 is fixed to the bottom end of the clamping device. The horizontal transmission 5 engages with the engagement structure 9 through the opposite or opposite movement of the two horizontal reference plates 1001, and the engagement structure 9 drives the base to rotate through the clamping device.

[0057] The engagement structure 9 comprises a reference rod 91 penetrating the central base plate 21, a directional gear 93 welded to the bottom end of the reference rod 91, and an annular gear 94. The hexagonal center plate 31 is coaxially welded to the top end of the reference rod 91. The directional gear 93 is integrally connected with the reference rod 91, and the annular gear 94 is rotatably installed on the peripheral surface of the reference rod 91. The surface of the reference rod 91 is also welded with a positioning ring 92, and the reference rod 91 is fixedly connected with the central base plate 21 through the positioning ring 92. The rotational movement of the annular gear 94 and the rotational movement of the reference rod 91 are independent of each other, and the positioning ring 92 rotates synchronously with the reference rod 91.

[0058] The transverse transmission 5 comprises two straight toothed racks 52 fixed on the surface of the two longitudinal reference plates 1002 respectively, a bevel toothed rack 51 hinged on the surface of the longitudinal reference plates 1002 and a limiting member for limiting the movement of the bevel toothed rack 51. The two bevel toothed racks 51 move synchronously and by the same distance through the engagement with the ring gear 94, wherein the two bevel toothed racks 51 move towards or away from each other simultaneously. The bevel toothed rack 51 rotates in the same direction intermittently through the engagement with the directional gear 93, as shown in FIG. 3-7. The teeth of the bevel toothed rack 51 and the directional gear 93 are both inclined to an angle, thereby ensuring that when the two longitudinal reference plates 1002 move towards each other, the two straight toothed racks 52 synchronize the movement of the two longitudinal reference plates 1002, while the bevel toothed rack 51 and the directional gear 93 engage and insert into the interior of the directional gear 93, causing the directional gear 93 to rotate, thereby synchronizing the rotation of the reference rod 91, the clamping device and the base with the directional gear 93. When the two longitudinal reference plates 1002 move away from each other, the two straight toothed racks 52 synchronize the movement of the two longitudinal reference plates 1002 to move towards each other. Since the teeth of the bevel toothed rack 51 and the directional gear 93 are both inclined to an angle, and the bevel toothed rack 51 is hinged on the surface of the longitudinal reference plates 1002, the straight toothed racks 52 cannot drive the directional gear 93 during the movement. The special structure of the directional gear 93 and the bevel toothed rack 51 causes the reference rod 91, the clamping device and the base to always rotate in the same direction, ensuring that the reference rod 91, the clamping device and the base rotate in the same direction intermittently, thereby realizing the welding work of different welding points on the same surface of the quartz piece 12.

[0059] The clamping device comprises a hexagonal center plate 31 located at the center, and a plurality of pressing members are arranged at equal intervals on the side surface of the hexagonal center plate 31. Each pressing member comprises a telescopic member 32 fixed on the side wall of the hexagonal center plate 31, an arc-shaped pressing plate 34 fixed on the end of the telescopic member 32, and a trajectory positioning plate 33 sleeved on the surface of the telescopic member 32. The telescopic member 32 comprises an integrated telescopic thin rod and a non-telescopic thick rod. A small spring is arranged on the outer periphery of the telescopic thin rod, which is used to press the inner periphery of the quartz flange 11 through the reaction generated when the small spring is compressed, so as to clamp and position the base. When the clamping device rotates, the base can rotate synchronously with the clamping device. One end of the small spring is fixed on the outer periphery of the telescopic member 32, and the other end is fixed on the end of the non-telescopic thick rod. The trajectory positioning plate 33 is fixed on the surface of the non-telescopic thick rod, and the surface of the arc-shaped pressing plate 34 is attached with thin silica gel, which is used to increase the friction between the clamping device and the quartz flange 11, and at the same time ensure the smoothness of the inner periphery of the quartz flange 11.

[0060] Referring to FIG. 7, a plurality of rectangular sliding grooves are arranged on the surface of the center base plate 21, and the trajectory positioning plate 33 penetrates the rectangular sliding grooves and linearly contacts the bottom surface of the center base plate 21, thereby reducing the friction when the trajectory positioning plate 33 moves synchronously with the non-telescopic thick rod.

[0061] The end of a horizontal reference plate 1001 extends upward with a vertical plate, the surface of which is fixed with a cylinder 6, the output end of which pushes the longitudinal reference plate 1002 to move linearly. The surface of the cylinder 6 is also provided with a cylinder controller, which is used to control the piston reciprocating stroke and piston movement speed of the cylinder 6. The piston stroke of the cylinder 6 is controlled by the cylinder controller, so as to control the sliding stroke of the longitudinal reference plate 1002 on the surface of the horizontal reference plate 1001. Since the longitudinal reference plate 1002 determines the movement distance of the helical gear rack 51 and the straight gear rack 52, the rotation number of the straight gear rack 52, the helical gear rack 51 and the directional gear 93 is ensured, so as to control the rotation angle or rotation process of the center base plate 21, the reference rod 91 and the base. A sliding groove is arranged in the interior of the horizontal reference plate 1001, the longitudinal reference plate 1002 is clamped in the sliding groove, and the groove length of the sliding groove is the stroke length of the longitudinal reference plate 1002. When the longitudinal reference plate 1002 slides from one end of the sliding groove to the other end, that is, reaches the welding position, the helical gear rack 51 drives the ring gear 94 to rotate by one quarter of a circle, that is, the base rotates, so as to change the position to be welded of the base to the nozzle of the automatic welding device, thereby realizing the connecting welding and improving the welding efficiency.

[0062] The device is provided with four quartz rods 13, the cylinder controller controls the stroke of the longitudinal reference plate 1002, that is, the rotation angle of the helical gear rack 51 driving the ring gear 94 is 90 degrees. If the number of the quartz rods 13 is not four, the rotation angle of the helical gear rack 51 driving the ring gear 94 needs to be adjusted.

[0063] For example, the device is provided with two quartz flanges 11, multiple quartz sheets 12 and four quartz rods 13. For one quartz sheet 12, the surface thereof has eight welding positions, which are distributed at the contact positions between the upper and lower end surfaces of the quartz sheet 12 and the quartz rods 13, and are divided into a first upper welding position, a second upper welding position, a third upper welding position, a fourth upper welding position, a first lower welding position, a second lower welding position, a third lower welding position and a fourth lower welding position. The first upper welding position corresponds to the first lower welding position, when the first upper welding position is welded, the base rotates by 90 degrees, and the second upper welding position or the fourth upper welding position is continuously welded, without manual operation, thereby reducing the workload of the workers. The connecting welding improves the welding efficiency and reduces the welding time.

[0064] The limiting member comprises a bent rod 53 fixed on the surface of the longitudinal reference plate 1002 and a telescopic spring 54 arranged on the outer periphery of the bent rod 53, one end of the telescopic spring 54 is pressed on the surface of the helical gear rack 51, and the other end is fixed on the end of the bent rod 53.

[0065] The surface of the helical rack 51 is also provided with a limiting hole for the bending rod 53 to pass through, and the hole diameter is larger than the rod diameter of the bending rod 53. The limiting hole is used to limit the swing angle of the helical rack 51, so as to ensure that the helical rack 51 can be inserted into the inside of the directional gear 93 in the forward direction. Since the helical rack 51 needs to swing at a certain angle, the limiting hole needs to leave a certain allowance for the rotation of the helical rack 51.

[0066] Working process: in the process that the cylinder controller controls the piston of the cylinder 6 to push a longitudinal reference plate 1002 to slide from an end of the sliding groove to the welding position, the longitudinal reference plate 1002 slides on the surface of the transverse reference plate 1001, the first straight rack 52 is engaged with the ring gear 94 while synchronously moving with the longitudinal reference plate 1002, the ring gear 94 is rotated by the thrust force and is engaged with the second straight rack 52, so that the second straight rack 52 moves the second straight rack 52 to move towards the first straight rack, that is, the two straight racks 52, the two longitudinal reference plates 1002 synchronously move, the distance is the same, and the movement directions are opposite, and the movement directions of the two straight racks 52 and the two longitudinal reference plates 1002 are both forward directions. When the longitudinal reference plate 1002 moves to the welding position, the cylinder controller controls the piston of the cylinder 6 to stop moving.

[0067] The cylinder controller controls the piston of the cylinder 6 to push a longitudinal reference plate 1002 to slide from the welding position of the sliding groove to the original end, that is, to reset, and the process is the same as the above process, and the movement directions are opposite, so that the welding of one welding position is completed. After four cycles, the welding of four welding positions is completed.

[0068] Referring to FIG. 9, the device is provided with two automatic welding devices, and the welding nozzles of the two welding devices are located at different heights, so that two quartz plates 12 can be welded at the same time, the welding time is reduced, and the welding efficiency is improved.

[0069] Since the spacing between the multiple quartz plates 12 is equal, only one automatic welding device can be provided. After the welding of the entire base is completed, the base is turned over, so that the un-welded points on the upper and lower end surfaces of the quartz plate 12 are welded. Although this method reduces the welding efficiency, it reduces the equipment cost and reduces the amount of daily maintenance of the power equipment, so that the daily maintenance of the power equipment is reduced.

[0070] The bottom end of the center base plate 21 is welded with a large ring gear 211, the large ring gear 211 is engaged with a driving member 24, and the driving member is hidden at the bottom end of the edge base plate 22. The driving member 24 comprises a second motor, a second circular gear at the end of the output shaft of the second motor, and a second motor controller for controlling the rotation, direction and speed of the output shaft of the second motor.

[0071] The transmission device comprises a longitudinal transmission 7 fixed to the outer surface of the longitudinal reference plate 1002, the longitudinal transmission 7 comprises a linkage 71, a plurality of longitudinally arranged cylindrical gears 73, and a synchronous belt 72 driving the plurality of cylindrical gears 73 to rotate synchronously. The cylindrical gears 73 are rotatably installed on the surface of the longitudinal reference plate 1002 and hidden inside the longitudinal reference plate 1002. The output shaft end of the linkage 71 is in butt joint and synchronous operation with one of the cylindrical gears 73. The cylindrical gears 73 comprise a linkage motor and a linkage controller for controlling the rotation speed, rotation direction and start-stop of the linkage motor.

[0072] The inside of the base is pressed with a spacer 8, which is detachably mounted. A plurality of quartz pieces 12 are equidistantly and horizontally arranged by the spacer 8. The device mounts all the quartz pieces 12 on the surface of the quartz rod 13, and ensures equidistant arrangement of the plurality of quartz pieces 12 by the spacer 8, so as to simplify the welding of the automatic welding device and improve the welding efficiency of the welding device without manual operation during the welding process.

[0073] A welding method for processing a quartz base comprises the following steps:

[0074] S1: welding the quartz rod 13 to the surface of the quartz flange 11, determining the relative position of the quartz rod 13 and the quartz flange 11, positioning the quartz flange 11 by the clamping device, and equidistantly and horizontally arranging the plurality of quartz pieces 12 by the spacer 8 in a detachable structure;

[0075] S2: triggering according to whether the welding point of the base is located in the monitoring range of the position sensor 46, when the welding point on the surface of the base does not enter the monitoring range of the position sensor 46, triggering the meshing structure 9 to work, so that the horizontal transmission 5 is engaged with the arc gear 442, thereby rotating the base by 90 degrees, so that the welding point on the surface of the base enters the monitoring range of the position sensor 46;

[0076] S3: when the welding point on the surface of the base enters the monitoring range of the position sensor 46, triggering the driving part 24 to rotate, so that the center base plate 21 and the edge base plate 22 rotate concentrically, so that the welding point on the surface of the base is located in the monitoring range of the position sensor 46;

[0077] S4: when the welding point of the base is located in the monitoring range of the position sensor 46, triggering the automatic welding device to start welding.

[0078] Working principle: Because the inclination angle of the rack of the bevel gear 93 and the rack gear 51 is the same, it is ensured that when the two longitudinal reference plates 1002 move in opposite directions, the two straight toothed racks 52 move synchronously with the two longitudinal reference plates 1002, and the bevel gear 93 and the bevel gear 51 mesh and insert into the inside of the bevel gear 93, so that the bevel gear 93 rotates, and the reference rod 91, the clamping device and the base rotate synchronously with the bevel gear 93. When the two longitudinal reference plates 1002 move away from each other, the two straight toothed racks 52 move synchronously in the opposite direction with the two longitudinal reference plates 1002, and because the inclination angle of the rack of the bevel gear 93 and the rack gear 51 is the same and the rack gear 51 is hingedly installed on the surface of the longitudinal reference plate 1002, the straight toothed rack 52 cannot drive the bevel gear 93 during movement. The special structure of the bevel gear 93 and the rack gear 51 causes the reference rod 91, the clamping device and the base to always rotate in the same direction, ensuring that the reference rod 91, the clamping device and the base rotate intermittently and in the same direction, thereby realizing the welding work of different welding points on the same quartz piece 12 surface.

[0079] When the welding point on the surface of the base does not enter the monitoring range of the position sensor 46, the engagement structure 9 is triggered to work, first converting the monitoring result of the position sensor 46 into an electrical signal output and transmitting it to the cylinder controller. The cylinder controller receives the electrical signal and controls the piston of the cylinder 6 to push the longitudinal reference plate 1002 forward. During the process of the longitudinal reference plate 1002 sliding from the terminal of the sliding groove to the welding position, the two longitudinal reference plates 1002 and the two straight toothed racks 52 move in the same direction, and the rack gear 51 moves in the forward direction. The engagement structure 9 is pushed by the rack gear 51 to drive the center plate 21, the clamping device and the base to rotate 90 degrees.

[0080] When the welding point on the surface of the base enters the monitoring range of the position sensor 46, the driving part 24 is triggered to rotate. The position sensor 46 outputs an electrical signal which is transmitted to the driving part 24 again. The output end of the driving part 24 is engaged with the large ring gear 211 to make the center plate 21, the clamping device and the base move circumferentially. The driving part 24 drives the center plate 21 to rotate in the opposite direction to the rotation direction of the rack gear 51, until the welding point of the base completely appears in the monitoring range of the position sensor 46, thereby correcting the position of the base. The engagement mode of the driving part 24 and the center plate 21 always corrects the relative position between the automatic welding device and the welding point of the base, ensuring the effectiveness of the welding and improving the welding efficiency.

[0081] When the welding point of the base is in the monitoring range of the position sensor 46, the automatic welding device welds the welding point on the surface of the base, and during the welding process, the angle adjusting part 41 drives the rotating plate body 44 to rotate on the surface of the longitudinal clamping plate 42, so as to change the welding position of the nozzle of the welding gun 45. The welding time is controlled, the welding points around the base are uniformly welded, the welding effect is improved, and local melting caused by high heat is prevented.

[0082] After welding, the cylinder controller controls the piston of the cylinder 6 to push the longitudinal reference plate 1002 to retreat, and during the process that the longitudinal reference plate 1002 slides from the welding position of the sliding groove to the original terminal, the two longitudinal reference plates 1002 and the two straight toothed racks 52 move in the same direction, and the helical toothed rack 51 moves in the retreat direction, the motion state of the meshing structure 9 is unchanged, and the welding points of the heat preservation barrel gradually disappear in the monitoring range of the position sensor 46. The above steps are repeated three times, the longitudinal transmission 7 moves the position of the automatic welding device by the distance between the quartz pieces 12, and the above steps are repeated. The device is also provided with a control center for setting the longitudinal and transverse motion of the automatic welding device, including motion time, motion distance and the like. According to the actual working requirements, the process distance is set in advance, for example, the longitudinal distance between the quartz pieces 12 and the quartz pieces 12, the angular interval between the welding points, the monitoring range of the position sensor 46 and the like.

[0083] S6: When the cylinder controller controls the piston of the cylinder 6 to move, the driving part 24 is engaged with the large ring gear 211, and if the position sensor 46 still cannot capture the welding point of the base, the automatic welding device stops welding, and manual starting is required again.
