Abstract
Description
Technical Field
[0001] This invention relates to the field of crystal material preparation, specifically to a quartz welding auxiliary device. Background Technology
[0002] Currently, the most common method for quartz tube welding in the industry is to place the PBN-quartz tube system horizontally or vertically, connect it to the evacuation system via a flange, and after the required vacuum level is reached, two people simultaneously use 6- or 12-head oxyhydrogen welding torches to weld the quartz tube to the quartz cap placed inside, forming a vacuum system. Although this method is simple and easy to implement, it is greatly affected by human factors during the sintering process. Due to uneven preheating before and after sintering, the thermal stress generated after sintering can easily cause tube cracking, leading to failure and the need to replace the quartz tube and repeat the evacuation process. In severe cases, it can even lead to the scrapping of polycrystalline material, reducing production efficiency, significantly increasing production costs, and hindering mass production. In addition, since the operation time is as long as more than 20 minutes, and the oxyhydrogen flame is high-temperature and high-heat, close-range operation can cause certain injuries to operators if not properly protected.
[0003] Chinese patent CN214327548U discloses an automatic quartz tube welding device, characterized in that the device includes an operating table, a control panel, a platform rotation device, a hydrogen-oxygen welding torch movement device, a hydrogen-oxygen welding torch, a hydrogen-oxygen welding torch adjustment device, and a hydrogen-oxygen valve. The control panel has three sets of control components: the first set includes indicator lights and an emergency stop button; the second set is for platform rotation control, including a platform rotation speed adjustment button, a platform rotation open button, and a platform rotation close button; the third set is for hydrogen-oxygen welding torch movement control, including a hydrogen-oxygen welding torch movement speed adjustment button, a hydrogen-oxygen welding torch upward movement button, a hydrogen-oxygen welding torch downward movement button, and a hydrogen-oxygen welding torch movement stop button. The aforementioned platform rotation device includes a platform, an upper flange, a lower flange, a reducer, a rotary motor, a correction plate, and O-rings. The platform is fixed to the upper and lower flanges with screws. The correction plate is fixed to the top of the platform with screws, and the O-rings are placed below the correction plate. The reducer and rotary motor are fixed to the bottom of the operating table. The reducer is connected to the rotary motor via a connecting shaft, driving the platform rotation device and the platform to rotate together. The aforementioned oxyhydrogen welding torch moving device includes a moving motor, a moving lead screw, a lead screw protective housing, a bearing sleeve, an oxyhydrogen welding torch fixing plate, and three separate support plates. The moving lead screw is placed in the lead screw protective housing, and its lower end is connected to the rotating shaft of the moving motor fixed to the operating table. The bearing sleeve is fitted onto the upper end of the moving lead screw and fixed to one end of the oxyhydrogen welding torch fixing plate with screws. The three separate support plates are each fixedly connected to the oxyhydrogen welding torch fixing plate as a single unit. There are three oxyhydrogen welding torches, all on the same plane and at 120° intervals from each other. The aforementioned oxyhydrogen welding torch adjustment device includes a fixing clamp, a horizontal moving guide rail, and an oxyhydrogen welding torch angle adjustment knob. The three oxyhydrogen welding torches are respectively fixed to three fixing clamps, which are connected to three oxyhydrogen welding torch angle adjustment knobs. The three oxyhydrogen welding torch angle adjustment knobs are respectively fixed to sliders on three horizontal moving guide rails, which are respectively fixed to three separate support plates. The three separate support plates are respectively fixed to oxyhydrogen welding torch fixing support plates. The oxyhydrogen valves are in three sets, each set consisting of one hydrogen valve and one oxygen valve. The inlets are connected to oxyhydrogen pipelines, and the outlets are connected to the inlets of the three oxyhydrogen welding torches via pressure-resistant hoses.
[0004] While the above solutions reduce the safety risks associated with close-range manual operation, they cannot achieve automated mass production. The solutions lack the aforementioned automatic feeding and unloading devices. Due to the transparency of quartz, accurate positioning using optical instruments is impossible during feeding and unloading. Furthermore, quartz is brittle and prone to breakage during clamping. In existing technologies, quartz tubes are often placed manually during sealing, which is inefficient and cannot guarantee the uniformity of the sealing position. Moreover, existing supply devices require multiple sets of actuators, resulting in high costs. Simply using a robotic arm to grip and feed the material also increases the risk of breakage.

Detailed Implementation
[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0031] Reference Figure 1 and Figure 2A quartz welding auxiliary device includes a welding device and an auxiliary component 1. The auxiliary component 1 includes a pushing device 11, a transmission device 12, a lifting device 13, receiving claws 14, a first linear actuator 141, a first push plate 142, a first support member 143, a rotating device 15, and a clamping device 16. The pushing device 11 is disposed on one side of the welding device and is used to supply unwelded quartz tubes. A gap exists between the pushing device 11 and the welding device. The lifting device 13 is disposed within the gap and is used to receive the quartz tubes pushed out by the pushing device 11. The transmission device 12 is disposed between the pushing device 11 and the lifting device 13. When the pushing device 11 is running, it drives the lifting device 13 to rise and fall through the transmission device 12. The transmission device 12 does not contain an actuator. The rotating device 15 is disposed above the lifting device 13 and has its own axis. Multiple receiving claws 14 are provided. Multiple receiving claws 14 are evenly arranged around the axis of the rotating device 15. The rotating device 15 can drive the receiving claws 14 to rotate around the axis of the rotating device 15. The receiving claws 14 are used to grip the quartz tube. The first linear actuator 141 is horizontally arranged above the pushing device 11, and the output end of the first linear actuator 141 points horizontally towards the rotating device 15. The first push plate 142 is fixedly arranged on the output end of the first linear actuator 141. The first support member 143 is arranged on the side of the receiving claw 14 away from the first push plate 142. The first support member 143 is located directly above the lifting device 13. The lifting device 13 drives the first support member 143 to rise and fall synchronously. The clamping device 16 is arranged on the side of the first support member 143 away from the first push plate 142. The clamping device 16 is used to clamp the quartz tube for welding by the welding device. At the same time, the clamping device 16 can drive the quartz tube to move along the axis of the output shaft of the first linear actuator 141.
[0032] The welding device has a ring structure. During welding, the clamping device 16 introduces the quartz tube into the ring of the welding device, and then a quartz block is placed into the opening of the quartz tube. The welding device operates to weld the quartz block into the quartz tube. The rotating device 15 drives the receiving claw 14 to rotate to one side of the pushing device 11. At this time, the receiving claw 14 is at its lowest point, and the pushing device 11 pushes out the quartz tube inside it. The quartz tube slides into the receiving claw 14, which clamps the quartz tube. Then the device rotates... The rotating device 15 drives the receiving claw 14 to rotate. Driven by the rotating device 15, the receiving claw 14 rotates to its uppermost position. At this time, the receiving claw 14 is located on one side of the first push plate 142. The rotating device 15 stops rotating, and the pushing device 11 starts. The pushing device 11 pushes out its internal quartz tube and places it into the receiving claw 14 located on the lower side. The pushing device 11 drives the lifting device 13 to rise through the transmission device 12. The first support member 143 rises under the drive of the lifting device 13. The bottom of the support member 143 is coplanar with the bottom of the receiving claw 14. Then, the first linear actuator 141 pushes the quartz tube on the upper receiving claw 14 out via the first push plate 142. The quartz tube slides into the clamping device 16 through the first support member 143. The clamping device 16 guides the slid-in quartz tube into the welding device. Simultaneously, a quartz block is placed at the opening of the quartz tube by a robotic arm. The welding device then welds the quartz tube. After welding, the clamping device 16... The quartz block that has been successfully welded slides out and is re-received by the original receiving claw 14. During the welding process, the rotating device 15 does not rotate. Subsequently, the rotating device 15 rotates, and the welded quartz tube can be removed from the receiving claw 14. At the same time, the pushing device 11 pushes the quartz tube back into the receiving claw 14. This cycle repeats, allowing the device to automatically supply quartz tubes while preventing them from falling and breaking during movement, thus reducing the operating cost of the device.
[0033] Reference Figure 1 , Figure 6 and Figure 10 The transmission device 12 includes a first transmission wheel 121, a first transmission belt 122, a protrusion 123, a second transmission wheel 124, and a second transmission belt 125. Multiple first transmission wheels 121 are horizontally arranged and are located at the lower part of the pushing device 11. The first transmission belt 122 is sleeved on the first transmission wheel 121, and the first transmission belt 122 and the first transmission wheel 121 are in a transmission engagement. The protrusion 123 is fixedly arranged on the outer sidewall of the first transmission belt 122, and the pushing device 11 can drive the first transmission belt 122 to rotate through the protrusion 123. Two second transmission wheels 124 are provided, and the two second transmission wheels 124 are respectively located on one side of the first transmission wheel 121 and the lifting device 13. The second transmission belt 125 is sleeved on the second transmission wheel 124, and the second transmission belt 125 and the second transmission wheel 124 are in a transmission engagement.
[0034] When the feeding device 11 is started, the feeding device 11 drives the protrusion 123, which in turn drives the first transmission belt 122 to rotate. The first transmission belt 122 drives the first transmission wheel 121 to rotate, and then the second transmission wheel 124 is driven to rotate. The second transmission belt 125 is driven to rotate, so that all the second transmission wheels 124 rotate, and thus the lifting device 13 can be driven.
[0035] Reference Figure 1 , Figure 7 and Figure 8 The lifting device 13 includes a first gear 131, a second gear 132, a rack 133, and a second support member 1331. The first gear 131 is fixedly disposed on one side of the second transmission wheel 124 along the axis of the second transmission wheel 124 away from the first transmission wheel 121. The second gear 132 is disposed on one side of the first gear 131, and the first gear 131 and the second gear 132 mesh with each other. The rack 133 is vertically disposed on one side of the second gear 132, and the rack 133 meshes with the second gear 132. The second support member 1331 is fixedly disposed on the upper part of the rack 133, and a fixing frame is fixedly disposed on the upper part of the second support member 1331. One end of the fixing frame away from the second support member 1331 is fixedly connected to the first support member 143.
[0036] When the second transmission wheel 124 rotates, the first gear 131 is driven to rotate by the second transmission wheel 124. Since the first gear 131 and the second gear 132 mesh with each other, when the first gear 131 rotates, the second gear 132 will also rotate, and the rack 133 will be driven to rise, thereby causing the second support 1331 and the first support 143 to rise together. In this way, the first support 143 can support the quartz tube, and the second support 1331 can also assist the pushing device 11 to ensure that the quartz tube can be pushed out more stably.
[0037] Reference Figure 3 and Figure 5 The transmission device 12 includes a guide assembly 126, which includes a guide rail 1261 and a guide groove. The guide rail 1261 is disposed on one side of the rack 133 along the length direction of the rack 133. The guide groove is formed on the side wall of the rack 133 along the length direction of the rack 133, and the guide rail 1261 and the guide groove are in sliding fit.
[0038] By setting the guide rail 1261, the rack 133 can be made more stable during lifting and lowering. When the rotating device 15 needs to rotate, the pushing device 11 retracts, and the weight of the first support 143 and the second support 1331 acts on the rack 133. The rack 133 is pressed down by the first support 143 and the second support 1331, and at the same time, the protrusion 123 located on the first transmission belt 122 will also be reset.
[0039] Reference Figure 1 , Figure 7 and Figure 9 The rotating device 15 includes a first rotary driver 151, a bracket 152, an extension rod 153, and a button 154. The bracket 152 is disposed on the side of the pushing device 11 near the clamping device 16. The first rotary driver 151 is fixedly disposed on the bracket 152. Multiple extension rods 153 are disposed evenly and fixedly disposed on the output end of the first rotary driver 151 around the axis of the output shaft of the first rotary driver 151. The length direction of the extension rods 153 is parallel to the radial direction of the output shaft of the first rotary driver 151. The button 154 is disposed on the bracket 152, and a controller is disposed on the bracket 152. When the extension rod 153 rotates, it can trigger the button 154. The button 154 drives the first rotary driver 151 to run through the controller.
[0040] When it is necessary to rotate the receiving claw 14, the first rotary driver 151 is activated. The first rotary driver 151 drives the extension rod 153 to rotate, and the receiving claw 14 located at the end of the extension rod 153 rotates. Since the bracket 152 is equipped with a button 154, when the extension rod 153 drives the receiving claw 14 to rotate to the lowest position, the button 154 will be triggered by the extension rod 153. The button 154 causes the first rotary driver 151 to stop running through the controller. It is worth noting that when one of the receiving claws 14 is at the lowest position, another receiving claw 14 will be at the highest position.
[0041] Reference Figure 1 and Figure 4 The clamping device 16 includes a fixing ring 161, a clamping claw 162, a mounting plate 163, a second rotary driver 164, and a roller 165. The fixing ring 161 is located on the side of the first support 143 away from the first push plate 142 along the axis of the output shaft of the first linear driver 141. The end of the fixing ring 161 is provided with a plurality of sliding grooves along the radial direction of the fixing ring 161, and the sliding grooves are arranged around the axis of the fixing ring 161. The clamping claw 162 is slidably disposed in the sliding groove along the length direction of the sliding groove. A pump body is provided on one side of the fixing ring 161, and the pump body can drive the clamping claw 162 to slide in the sliding groove. The mounting plate 163 is fixedly disposed on the clamping claw 162. The second rotary driver 164 is fixedly disposed on the side wall of the fixing plate. The roller 165 is fixedly disposed on the output end of the second rotary driver 164.
[0042] When the first linear actuator 141 pushes the quartz tube out of the receiving claw 14, the quartz tube enters the ring of the fixing ring 161 through the first support member 143. The pump body on one side of the fixing ring 161 is started, and the pump body drives the clamping claw 162 to slide along the length direction of the sliding groove. The clamping claw 162 drives the roller 165 to move towards the quartz tube through the mounting plate 163 and finally clamps the quartz tube. Then the second rotary actuator 164 drives the roller 165 to rotate, and the quartz tube slides into the welding device under the drive of the roller 165.
[0043] Reference Figure 1 and Figure 2 The auxiliary component 1 also includes a first guide sleeve 17 and a second guide sleeve 18; the first guide sleeve 17 has an arc-shaped structure, and the axis of the first guide sleeve 17 is collinear with the axis of the rotating device 15. The first guide sleeve 17 is used to guide the unwelded quartz tube to rotate with the receiving claw 14; the second guide sleeve 18 is disposed on one side of the first guide sleeve 17, and the second guide sleeve 18 can guide the welded quartz tube to retract away from the receiving claw 14.
[0044] The first guide sleeve 17 prevents the rotating device 15 from falling off when it rotates the unwelded quartz tube, while the second guide sleeve 18 guides the welded quartz tube to detach from the receiving claw 14.
[0045] Reference Figure 5 and Figure 7 Auxiliary component 1 also includes a material ejector 19, which includes an ejector plate 191, a third rotary driver 192, a synchronous pulley 193, and a synchronous belt 194. The ejector plate 191 is located on the side of the receiving claw 14 away from the second guide sleeve 18. The ejector plate 191 is used to receive the quartz tube guided out by the second guide sleeve 18. The ejector plate 191 has a through groove along its length. The third rotary driver 192 is located below the ejector plate 191. There are two synchronous pulleys 193, which are arranged along the length of the ejector plate 191. One of the synchronous pulleys 193 is fixedly connected to the output end of the third rotary driver 192. The synchronous belt 194 is sleeved on the synchronous pulley 193 and the synchronous belt 194 is in a transmission cooperation with the synchronous pulley 193.
[0046] After the quartz tube is guided away by the second guide sleeve 18, it falls onto the ejector plate 191. At this time, the third rotary drive 192 starts after the rotating device 15 stops running. The third rotary drive 192 drives the synchronous belt 194 to rotate through the synchronous pulley 193. Under the drive of the synchronous belt 194, the quartz tube can completely retract from the receiving claw 14.
[0047] Reference Figure 2 and Figure 10The feeding device 11 also includes a second linear driver 111 and a second pusher plate 112; the second linear driver 111 is horizontally arranged on one side of the rotating device 15, and the output end of the second linear driver 111 points horizontally towards the rotating device 15; the second pusher plate 112 is fixedly arranged on the output end of the second linear driver 111, and the second pusher plate 112 can push the protrusion 123. A lifting shell is provided at the lower part of the second pusher plate 112, and the lifting shell is used to lift the quartz tube. The transmission device 12 is arranged on the lifting shell.
[0048] When the second linear actuator 111 is activated, and the quartz tube is present on the lifting shell, the second linear actuator 111 pushes the quartz tube located on the lifting shell out through the second push plate 112.
[0049] Reference Figure 2 and Figure 9 The feeding device 11 also includes an inclined plate 113 and a baffle 114; the inclined plate 113 is inclinedly disposed on one side of the lifting shell, and the end of the inclined plate 113 near the lifting shell is lower than the end of the inclined plate 113 away from the lifting shell; two baffles 114 are respectively disposed on both sides of the inclined plate 113, and a quartz tube is supported on the inclined plate 113.
[0050] Since the quartz tubes are arranged on the inclined plate 113, the rotating device 15 does not rotate during welding, the output end of the second linear actuator 111 is in the extended state, and the second push plate 112 blocks the lifting shell. The quartz tubes located on the inclined plate 113 cannot slide into the lifting shell. Before the rotating device 15 is started, the second linear actuator 111 starts to retract, and the quartz tubes slide from the inclined plate 113 into the lifting shell.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
