Description

Technical Field

[0001] The invention relates to the technical field of quartz welding, in particular to a quartz welding auxiliary heating device. Background Art

[0002] Quartz welding is a special type of welding method that uses high temperature to bond quartz and metal (or other quartz materials) together. This welding method is widely used in microelectronics, optics, physical laboratories, and space technology. Quartz materials need to be preheated before welding. At this time, a heating device is needed to heat the quartz material to improve the welding performance of the quartz material and ensure the quality of welding.

[0003] Defect 1: The existing heating device is generally fixed on the inner wall of the pipeline through an auxiliary mechanism, and the heating device needs to be fixed and removed manually. After manual welding, it is manually removed and moved to the next welding position. This is repeated to complete the welding work of the entire pipeline, which seriously affects work efficiency;

[0004] In order to solve the above-mentioned defect one, the prior art one (application number: 202323628129.0, application date of 2023-12-29 Chinese patent) discloses a welding heating device. By arranging magnetic wheels on both sides of the fixed plate, the welding heating device can be moved to the position to be welded by rolling the magnetic wheels, which makes the movement of the welding heating device more labor-saving. The magnetic adjustment device can be conveniently adsorbed or released from the weldment, and can provide a large magnetic attraction force to the weldment. The welding heating device is fixed to the weldment as a whole in cooperation with the magnetic wheel. There is no need to set up an additional fixing mechanism, which saves the steps of fixing connection and removal, and is conducive to improving welding efficiency. After fixing, start the heating belt to heat the pipe at the welding position, and turn off the heating belt after heating to the required temperature. Cut off the magnetic lines of force of the magnetic adjustment device, release the magnetic attraction of the magnetic adjustment device to the weldment, and enable the magnetic wheel to roll along the weldment, thereby transferring the welding heating device to the next position to be welded and heated. By setting up the magnetic wheel and the magnetic adjustment device, it is greatly convenient to fix and transfer the welding heating device on the welded part, without the need to set up an additional fixing mechanism, saving the steps of fixing connection and removal, which is conducive to improving welding efficiency. Furthermore, by setting up a heating belt to perform electromagnetic induction heating on the pipeline, the heating uniformity and heating efficiency are improved;

[0005] Defect 2: At present, the traditional heating methods for catheter rack welding mainly use the flame of a torch for heating or the electric heating using a heating plate. The welding process of the catheter rack structure is often carried out in confined spaces and at high altitudes. When heating the catheter before or after welding, the arrangement and use of the torch are relatively complicated and cumbersome. Before and after heating, a large amount of manual coordination is required to install the torch in the appropriate position or adjust the position of the torch. The above process has low working efficiency and is not conducive to improving the convenience of construction;

[0006] In order to solve the above-mentioned defect 2, the second prior art (application number: 202321598273.1, Chinese patent with application date of 2023-06-21) discloses a welding heating device, including a frame air pipe, a flame nozzle and a positioning connection assembly. The frame air pipe can be arranged around the tooling to be heated, and the air inlet end of the frame air pipe is connected to the fuel gas source; the positioning connection assembly is arranged on the frame air pipe and can be detachably connected to the tooling to be heated. In other words, the frame air pipe arranged around the side of the tooling to be heated is positioned by the positioning connection assembly, and there is no need to manually support the frame air pipe, which can save labor, facilitate operation, and improve construction convenience. A flame nozzle is provided at the air outlet end of the frame air pipe, and the flame nozzle can spray flame on the tooling to be heated. In other words, with the assistance of the positioning connection assembly, the flame nozzle can stably and accurately spray flame to the position where the tooling to be heated needs to be heated, thereby ensuring the heating effect;

[0007] The above mechanism heats the heated tooling by spraying flames through a flame nozzle, but the flame heating method is prone to cause excessive temperature at a certain point when heating the quartz plate, which in turn affects subsequent welding, and the temperature is difficult to control. At the same time, the flame heating speed is relatively slow, resulting in low work efficiency, and the heating wire of the heating area cannot be opened according to quartz plates of different sizes, resulting in energy waste.

[0008] Therefore, we propose a quartz welding auxiliary heating device to solve the above problems. Summary of the invention

[0024] Compared with the prior art, the beneficial effects of the present invention are: the quartz welding auxiliary heating device adopts a new structural design, and its specific contents are as follows:

[0025] (1) The quartz plate is transported by conveying rollers, and then the heat generated by multiple heating tubes can preheat the welding area of ​​the quartz plate before welding, effectively preventing the quartz plate from cracking and improving the heating efficiency. At the same time, the staff can turn on the control switch according to the size of the quartz plate and start the heating tubes in different areas to preheat the quartz plate, so that the heating temperature can be adjusted according to different quartz plate materials and welding processes to ensure welding quality, reduce unnecessary energy waste, and reduce production costs;

[0026] Furthermore, when the operator rotates the control switch in the reverse direction, the movable contact switch separates from the fixed contact switch, and the corresponding heating tube is powered off; and when the operator rotates the control switch in the forward direction, the movable contact switch contacts the fixed contact switch, and the corresponding heating tube is powered on, thereby facilitating the opening and closing of the control device.

[0027] (2) The sleeve is driven by a motor to rotate in the forward direction, so that the sleeve drives the reciprocating screw to rotate by means of a ratchet assembly, and then the movable sleeve drives the clamping plate to move, which can be adjusted according to quartz plates of different sizes;

[0028] Furthermore, after the adjustment is completed, the lifting plate and the clamping plate are driven upward by the electric push rod, and at the same time, the rack drives the meshing driving gear to rotate, so that the driving gear drives the transmission rod to rotate by the bevel gear set, and then the cam rotates and squeezes the fitting block, causing it to move, and drives the clamping plate to move. At this time, the two clamping plates move relative to each other and clamp and fix quartz plates of different sizes, thereby preventing the quartz plate from shifting during the subsequent welding process and affecting the welding effect;

[0029] Furthermore, when the cam does not press the fitting block, the elastic force of the reset spring is used to drive the connecting plate to reset, so that the two clamping plates move in opposite directions and no longer clamp and fix the quartz plate;

[0030] (3) The heating wire heats the air in the box, and the hot air in the box is transported to the movable tubes on both sides through two hoses by an electric fan, and blown out from multiple air outlets, thereby uniformly heating the welding area of ​​the quartz plate to avoid excessive temperature at a certain point of the quartz plate;

[0031] Furthermore, when the motor drives the sleeve to rotate in the opposite direction, the reciprocating screw rod does not rotate, and the pulley assembly is used to drive the rotating rod to rotate synchronously, so that the half gear intermittently drives the meshing driven gear to rotate, and then the movable tube rotates. When the half gear is not meshed with the driven gear, the movable tube rotates in the opposite direction under the stored force of the torsion spring, and the above operation is repeated, so that the movable tube swings back and forth, which can increase the range of hot air blowing and thus improve the heating efficiency.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-Figure 10 ,The present invention provides the following technical solutions: a quartz welding auxiliary heating device;

[0045] Embodiment 1: In order to solve the problem that the flame heating method in the prior art is easy to cause the temperature of a certain place to be too high when heating the quartz plate, which in turn affects the subsequent welding, and the temperature is difficult to control, and the speed of flame heating is relatively slow, resulting in low work efficiency, and the heating wire of the heating area cannot be turned on according to the different sizes of quartz plates, resulting in energy waste, the following scheme is disclosed, and specific reference is made to Figure 1-Figure 5 As shown, it includes a frame 1, and conveying rollers 2 for conveying quartz are installed at equal intervals on the upper inner side of the frame 1, and a tube body 4 is fixedly connected to the front of the frame 1, and heating tubes 3 are installed at equal intervals on the inner side of the frame 1 below the conveying rollers 2;

[0046] The top of the inner wall of the tube body 4 is connected with a control switch 5 at equal intervals, and a movable contact switch 27 is fixed to the outer side of the lower end of the control switch 5. The rear end of the inner wall of the tube body 4 is bolted with a fixed contact switch 26 at equal intervals. The heating tube 3 is connected to the fixed contact switch 26 through a wire. The control switch 5 and the tube body 4 are rotatably connected. The positions of the movable contact switch 27 and the fixed contact switch 26 correspond. The lower part of the inner side of the frame 1 is fixedly connected with a support plate 25, and the top of the upper support plate 25 is connected to a reciprocating screw rod 6. A motor is installed on the right side of the upper surface of the support plate 25, a sleeve 7 is sleeved on the outer side of the right end of the reciprocating screw rod 6, the right end of the sleeve 7 is fixedly connected to the output end of the motor, and a ratchet assembly 10 is installed between the sleeve 7 and the reciprocating screw rod 6, the positions of the driven gear 12 and the half gear 11 correspond, and the driven gear 12 and the half gear 11 are meshed, the movable tube 13 forms a forward and backward reciprocating swing structure through the driven gear 12, the half gear 11 and the torsion spring 15, and the reciprocating screw rod 6 forms a unidirectional rotation structure through the sleeve 7 and the ratchet assembly 10;

[0047] When in use, the quartz plate is transported by the conveying roller 2 so that the quartz plate moves to the position of the welding machine. At this time, the heat generated by the multiple heating tubes 3 when working can preheat the welding area of ​​the quartz plate before welding, effectively prevent the quartz plate from cracking, and improve the heating efficiency. At the same time, the staff can turn on the control switch 5 according to the size of the quartz plate, and start the heating tubes 3 in different areas to preheat the quartz plate, so that the heating temperature can be adjusted according to the different quartz plate materials and welding processes to ensure the welding quality, reduce unnecessary energy waste, and reduce production costs. Then, when the staff rotates the control switch 5 in the reverse direction, the movable contact switch 27 is separated from the fixed contact switch 26, and the corresponding heating tube 3 is powered off. When the control switch 5 is rotated forward, the movable contact switch 27 contacts the fixed contact switch 26, and the corresponding heating tube 3 can be powered on, which makes it easy to turn on the heating tubes 3 in different areas to preheat the quartz plate.

[0048] Embodiment 2: Different from Embodiment 1, this embodiment utilizes the movable tube 13 to swing back and forth, which can increase the range of hot air blowing. Figure 1 , Figure 2 , Figure 8 and Fig. 9As shown, the front and rear sides of the inner wall of the frame 1 are connected with a rotating rod 14; the outer side of the right end of the rotating rod 14 is sleeved and fixed with a half gear 11, and the rotating rod 14 and the outer side of the right end of the sleeve 7 are connected by a pulley assembly. The inner wall of the frame 1 is provided with movable tubes 13 above the two rotating rods 14, and the reciprocating screw rod 6 and the sleeve 7 are connected with the support plate 25 by bearings. The two movable tubes 13 are symmetrically distributed above the inner side of the frame 1, and the movable tube 13 is rotatably connected to the frame 1. The interior of the movable tube 13 is hollow, and the two movable tubes 13 are connected to the inner side of the frame 1. Air outlets are provided at equal intervals on opposite surfaces of the movable tube 13, and a driven gear 12 is fixedly sleeved on the outer side of the right end of the movable tube 13. Torsion springs 15 are installed at the connection positions between the outer sides of the right ends of the two movable tubes 13 and the frame 1. A box body 28 is fixedly connected to the top of the lower support plate 25, and an electric fan 29 and an electric heating wire 30 are respectively installed inside the box body 28. The box body 28 and the two movable tubes 13 are connected through a hose 31. Air inlets are provided below both sides of the box body 28, and the electric fan 29 is arranged directly below the electric heating wire 30.

[0049] The electric heating wire 30 is started to heat the air in the box body 28, and then the electric fan 29 is started. The electric fan 29 transports the hot air in the box body 28 to the movable tube 13 through the hose 31, and blows it out evenly from the air outlet on the movable tube 13, so as to evenly heat the welding area of ​​the quartz plate to avoid excessive temperature at a certain place of the quartz plate. Then, when the motor drives the sleeve 7 to rotate in the opposite direction, the reciprocating screw rod 6 does not rotate, and the pulley assembly is used to drive the rotating rod 14 to rotate synchronously, so that the half gear 11 rotates and intermittently drives the meshing driven gear 12 to rotate, and then the movable tube 13 rotates. When the half gear 11 is not meshed with the driven gear 12, the movable tube 13 rotates in the opposite direction under the stored force of the torsion spring 15, and the above operation is repeated, so that the movable tube 13 swings back and forth, which can increase the range of hot air blowing and thus improve the heating efficiency.

[0050] Embodiment 3: Different from Embodiment 2, this embodiment utilizes two clamping plates 21 to move relative to each other, and can clamp and fix quartz plates of different sizes, so as to avoid displacement during the subsequent welding process and affect the welding effect. For details, refer to Figure 1 , Figure 2 , Figure 6-Figure 8 and Fig.10As shown, a movable sleeve 8 is sleeved on the outer side of the reciprocating screw rod 6, and the movable sleeve 8 and the reciprocating screw rod 6 are threadedly connected, and the bottom of the movable sleeve 8 and the top of the upper support plate 25 are slidably connected, and an electric push rod 9 is installed on one side of the movable sleeve 8 and the top of the upper support plate 25, and a lifting plate 16 is fixed to the output end of the electric push rod 9, and a rack 18 is fixedly connected to the other side of the top of the two movable sleeves 8. A driving gear 17 is connected to the lower part of the lifting plate 16, and a transmission rod 19 is arranged above the driving gear 17 inside the lifting plate 16. The driving gear 17 is rotatably connected to the inside of the lifting plate 16 through an axis, and the driving gear 17 and the rack 18 are meshed. The transmission rod 19 is rotatably connected to the lifting plate 16. Inside, the bottom end of the transmission rod 19 is connected to the shaft end of the driving gear 17 through a bevel gear set, a cam 20 is fixedly sleeved on the outer side of the upper end of the transmission rod 19, a clamping plate 21 is provided between the opposite surfaces of the two lifting plates 16, and a connecting plate 23 is fixedly connected to the four corners of the side of the clamping plate 21, and the end of the connecting plate 23 away from the clamping plate 21 extends into the interior of the lifting plate 16, and a return spring 24 is installed between one end of the connecting plate 23 and the inner wall of the lifting plate 16, and a fitting block 22 is fixed to the middle position of the side of the clamping plate 21, the fitting block 22 corresponds to the position of the cam 20, and the side of the fitting block 22 away from the clamping plate 21 is inclined, and the outer side of the cam 20 fits with the inclined surface of the fitting block 22;

[0051] When the quartz plate moves to the position of the welding machine, the motor is started, and the motor drives the sleeve 7 to rotate in the forward direction, so that the sleeve 7 drives the reciprocating screw rod 6 to rotate by means of the ratchet assembly 10, and then the movable sleeve 8 drives the lifting plate 16 on the right and the clamping plate 21 on the right to move, so that the spacing between the two clamping plates 21 can be adjusted according to the different sizes of quartz plates, and then the two electric push rods 9 are started, so that the electric push rods 9 drive the lifting plate 16 to move upward, and at the same time, the meshing driving gear 17 is driven to rotate by means of the rack 18, so that the driving gear 17 drives the transmission rod 19 to rotate by means of the bevel gear set, and then the cam The wheel 20 rotates and squeezes the fitting block 22, causing it to move, and drives the clamping plate 21 to move. At this time, the two clamping plates 21 move relative to each other and clamp and fix quartz plates of different sizes, thereby preventing the quartz plates from shifting during the subsequent welding process and affecting the welding effect. After that, when the welding is completed, as the reciprocating screw 6 continues to rotate, the movable sleeve 8 is reset, and then the electric push rod 9 drives the lifting plate 16 to move downward, so that the cam 20 no longer squeezes the fitting block 22, and then the connecting plate 23 is reset under the elastic force of the reset spring 24, and drives the clamping plate 21 to reset, so that it no longer clamps and fixes the quartz plate.
