Description

Technical Field

[0001] The present application belongs to the technical field of processing equipment, and specifically relates to a positioning device and a fusing device. Background Art

[0002] Chalcogenide glass has good infrared transmittance, and its transmission band covers from short wave to long wave. At the same time, chalcogenide glass also has many excellent characteristics such as low price and continuously adjustable optical properties with composition. However, as an oxygen-free amorphous material, chalcogenide glass needs to be strictly isolated from oxygen-containing environment during its synthesis and high-temperature melting process. Otherwise, the raw materials or glass liquid will come into contact with the oxygen-containing environment and oxidize, which will eventually cause the transmittance of the finished glass to drop seriously or even become completely devitrified. Therefore, before melting chalcogenide glass, high-purity raw materials need to be loaded into a quartz ampoule according to a certain stoichiometric ratio, and then the bottle mouth needs to be sealed with a hydrogen-oxygen flame.

[0003] When sealing with oxyhydrogen flame, due to the extremely high flame temperature, it is very easy for the local temperature of the weld to be too high and melt through the weld, or the uneven temperature of the weld to cause stress concentration and further form cracks, causing outside air to enter the ampoule and cause oxidation of the raw materials. Utility Model Content

[0004] The technical problem to be solved by the present application is that in the existing ampoule sealing process, it is very easy for the local temperature of the weld to be too high, resulting in the weld melting through, or the weld temperature is uneven, resulting in stress concentration and further crack formation. In order to solve this technical problem, a positioning device and a fusing device are provided that can ensure that the weld is heated evenly.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0031] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a positioning device 100 , including a mounting seat 111 , a first mounting plate 112 , and at least two sets of supporting components disposed on the first mounting plate 112 .

[0032] The first mounting plate 112 is rotatably connected to the mounting seat 111 around a first axis, at least two groups of support assemblies are arranged on the first mounting plate 112 at intervals along a first direction perpendicular to the first axis, and each support assembly includes a plurality of support members 113 arranged at intervals along a second direction, each support member 113 can rotate around an axis parallel to the first direction, and all support members 113 can jointly support the workpiece so that the workpiece can rotate.

[0033] Furthermore, the positioning device further includes a follower assembly 120 , and the follower assembly 120 includes a follower 121 . The follower 121 can abut against one end of the workpiece along the first direction and rotate with the workpiece.

[0034] The first direction is perpendicular to the first axis and the second direction, and the second direction is parallel to the first axis. Figure 1 In the illustrated embodiment, the first axis is a horizontal axis, and the first direction is a variable direction.

[0035] It should be noted that, in this embodiment, the workpiece is an ampoule bottle 200. In other embodiments, the workpiece may also be other products that need to be rotated, which is not limited here. This application is described by taking the ampoule bottle 200 as an example.

[0036] By using the above-mentioned positioning device, the first mounting plate 112 is rotated around the first axis so that the first mounting plate 112 is tilted, and the ampoule bottle 200 is placed on the multiple support members 113. The follower 121 can support the bottom end of the ampoule bottle 200 and rotate with the ampoule bottle 200, thereby ensuring that the ampoule bottle 200 can rotate and is placed more stably on the positioning device. Next, the mouth of the ampoule bottle 200 is welded and sealed. Since the ampoule bottle 200 can rotate stably, the weld is heated evenly, avoiding local excessive temperature causing the weld to melt through. At the same time, it can also avoid uneven weld temperature causing stress concentration and cracks, thereby preventing outside air from entering the ampoule bottle 200 to cause oxidation of the raw materials, thereby improving the yield of the finished glass.

[0037] It should be noted that, during the rotation of the first mounting plate 112, the first direction can become a horizontal direction, and at this time, the ampoule bottle 200 placed on the multiple support members 113 also remains horizontal. During the rotation of the ampoule bottle 200, one end of the ampoule bottle 200 abuts against the follower 121, but the ampoule bottle 200 may move along the first direction away from the end of the follower 121, thereby causing the ampoule bottle 200 to move relative to the oxyhydrogen flame, so that the ampoule bottle 200 may be heated unevenly. However, by rotating the first mounting plate 112, the first mounting plate 112 is tilted relative to the horizontal direction, the bottom of the ampoule bottle 200 can be supported by the follower 121, and the ampoule bottle 200 will not move relative to the support member 113 under the action of gravity, thereby ensuring the stability of welding and the welding sealing effect.

[0038] In addition, it can be understood that by setting the first mounting plate 112 to be rotatable around the first axis to adjust the inclination angle of the first mounting plate 112, the positioning device can be suitable for use in different scenarios, such as a scenario where the bottle mouth height of the ampoule bottle 200 needs to be adjusted.

[0039] In one embodiment, the positioning device further comprises a frame 110, and the mounting seat 111 and the follower assembly 120 are both disposed on the frame 110. Furthermore, a plurality of universal wheels are disposed at the bottom of the frame 110 to facilitate the movement of the positioning device.

[0040] See also Figure 2 and Figure 3 In one embodiment, the positioning device further includes an adjusting member 114, which is disposed on the mounting seat 111. One end of the first mounting plate 112 is rotatably connected to the mounting seat 111 around the first axis, and the adjusting member 114 is connected to the other end of the first mounting plate 112 to adjust the distance between the other end of the first mounting plate 112 and the mounting seat 111, thereby driving the first mounting plate 112 to rotate around the first axis.

[0041] Furthermore, the adjusting member 114 includes a first rod portion 1141 and a second rod portion 1142. One end of the first rod portion 1141 is hinged to the mounting seat 111, and the other end is hinged to the second rod portion 1142. One end of the second rod portion 1142 away from the first rod portion 1141 is hinged to the first mounting plate 112, thereby achieving adjustment of the height of the end portion of the first mounting plate 112 relative to the mounting seat 111 and adjustment of the inclination angle of the first mounting plate 112.

[0042] In one embodiment, the positioning device also includes a first connecting seat 115 and a second connecting seat 116, which are arranged at intervals on the top of the mounting seat 111, one end of the first mounting plate 112 is rotatably connected to the first connecting seat 115 around a first axis, and one end of the first rod portion 1141 is hinged to the second connecting seat 116.

[0043] In one embodiment, each support assembly further includes a plurality of mounting blocks 117 , which are spaced apart on the first mounting plate 112 along the second direction, and each support member 113 is rotatably connected to a corresponding mounting block 117 around an axis parallel to the first direction.

[0044] Specific to Figure 2 In the illustrated embodiment, each support assembly includes two mounting blocks 117 and two support members 113. In addition, optionally, the support member 113 is a rolling bearing or a roller.

[0045] In one embodiment, the follower assembly 120 further includes a second mounting plate 122, which is rotatably arranged around a second axis parallel to the first axis, and the follower 121 is arranged on the second mounting plate 122. It should be explained that the first mounting plate 112 can rotate around the first axis to adjust the tilt angle, and in order to ensure that the follower 121 can accurately abut against the bottom of the ampoule bottle 200 and rotate with the ampoule bottle 200, the second mounting plate 122 is arranged to be rotatable around the second axis to adjust the angle of the first mounting plate 112.

[0046] In one embodiment, the follower 121 is rotatable around an axis parallel to the first direction, so as to rotate with the ampoule 200 after supporting the bottom of the ampoule 200, thereby ensuring smoother rotation of the ampoule 200. Further, the follower assembly 120 also includes a connecting plate 123, which is fixedly connected to the first mounting plate 112 to rotate around the first axis with the first mounting plate 112, and the second mounting plate 122 is disposed on the connecting plate 123. At this time, the first axis and the second axis coincide, so that the first mounting plate 112 and the second mounting plate 122 rotate around the first axis at the same time, thereby ensuring that the rotation center of the follower 121 coincides with the rotation center of the ampoule 200 while achieving angle adjustment.

[0047] In another embodiment, the follower 121 includes a plurality of universal balls. In this way, the universal balls can rotate with the ampoule 200 without coinciding the rotation center of the ampoule 200 with the rotation center of the universal balls, thereby ensuring the smoothness of the rotation of the ampoule 200. Of course, it is preferred that the follower 121 rotates around an axis parallel to the first direction, and this embodiment is used for description below.

[0048] In one embodiment, the follower 121 can be adjusted relative to the second mounting plate 122 along a third direction perpendicular to the second axis to ensure that the rotation center of the follower 121 coincides with the rotation center of the ampoule bottle 200. Figure 2 and Figure 3 In the illustrated embodiment, the third direction is a direction parallel to the surface of the second mounting plate 122 facing the supporting assembly, that is, the third direction is also a variable direction.

[0049] It is understandable that when processing ampoule bottles 200 of different sizes, the rotation center positions of ampoule bottles 200 of different sizes are different. If the rotation center of the follower 121 is staggered with the rotation center of the ampoule bottle 200, the follower 121 will not rotate with the ampoule bottle 200 and will hinder the rotation of the ampoule bottle 200. Therefore, it is necessary to adjust the position of the follower 121 along the third direction to ensure that the rotation center of the follower 121 coincides with the rotation center of the ampoule bottle 200.

[0050] Furthermore, the follower assembly 120 further includes an adjustment block, which is connected to the second mounting plate 122 and can adjust the position along the third direction, and the follower 121 is rotatably connected to the adjustment block. Of course, when processing the same type of ampoule bottle 200, the follower 121 can also be directly rotatably connected to the second mounting plate 122, which is not limited here.

[0051] In one embodiment, the positioning device further includes a clamping assembly 130, which is disposed on the frame 110 and located on one side of the mounting seat 111. The clamping assembly 130 can clamp one end of the workpiece away from the follower 121. In this way, after the mouth of the ampoule bottle 200 is heated to a high temperature softening state, the rotation of the ampoule bottle 200 is first stopped, and then the mouth of the ampoule bottle 200 is clamped by the clamping assembly 130 to fix the mouth of the ampoule bottle 200, and then the ampoule bottle 200 is continuously rotated, the mouth of the bottle is fixed, and the bottle body rotates, and the mouth of the bottle is twisted so that the mouth of the bottle is completely sealed.

[0052] It should be explained that the above-mentioned heating at the bottle mouth refers to the position close to the bottle mouth of the ampoule bottle 200, and the bottle mouth end is the end where the bottle mouth is opened, that is, the heating position is close to the bottle mouth end.

[0053] Furthermore, the second mounting plate 122 is connected to the connecting plate 123 so as to be reciprocatingly movable along the first direction. After the bottle mouth of the ampoule bottle 200 is twisted and the bottle mouth is sealed, the second mounting plate 122 moves along the first direction away from the supporting assembly, thereby driving the bottle body of the ampoule bottle 200 to separate from the bottle mouth end clamped on the clamping assembly 130. At this time, the end of the bottle body away from the follower 121 has been welded.

[0054] Furthermore, the positioning device further includes a locking member 124, one end of which is hinged to the first mounting plate 112, and the other end of which is detachably connected to the second mounting plate 122, so as to fix the second mounting plate 122 relative to the first mounting plate 112. In this way, when welding and sealing the ampoule bottle 200, the locking member 124 is connected to the second mounting plate 122 to ensure that the follower 121 can support the bottom of the ampoule bottle 200; after welding and sealing, the locking member 124 is separated from the second mounting plate 122, and the second mounting plate 122 and the ampoule bottle 200 can slide downward under the action of gravity, so that the bottle body and the bottle mouth end are separated.

[0055] In actual application, the locking member 124 is provided with a locking groove 1241, and the second mounting plate 122 is provided with a locking protrusion 125. When the second mounting plate 122 moves to a preset position, the locking member 124 rotates, and the locking groove 1241 can be buckled on the locking protrusion 125, thereby fixing the locking member 124 and the locking protrusion 125 in the first direction, thereby fixing the second mounting plate 122 relative to the first mounting plate 112.

[0056] In one embodiment, the follower assembly 120 also includes a fixed block 126 and a buffer member 127. The fixed block 126 is fixedly connected to the connecting plate 123 and is located on the side of the second mounting plate 122 away from the supporting assembly. The buffer member 127 is connected to the side of the fixed block 126 toward the second mounting plate 122. The second mounting plate 122 can abut against the buffer member 127 during the movement of the second mounting plate 122 along the first direction toward the fixed block 126, thereby buffering the second mounting plate 122 through the buffer member 127.

[0057] Specific to Figure 2 In the illustrated embodiment, the buffer 127 is a spring. When the second mounting plate 122 and the ampoule bottle 200 slide downward under the influence of gravity, the second mounting plate 122 abuts against the buffer 127, thereby buffering the second mounting plate 122, preventing the ampoule bottle 200 from being subjected to a large vibration, and further preventing the ampoule bottle 200 from being damaged or falling off from the positioning device.

[0058] In one embodiment, the clamping assembly 130 includes a bracket 131 and a clamping member 132, the clamping member 132 is rotatably connected to the bracket 131 around a third axis parallel to the first axis, and the clamping member 132 can adjust its position along a fourth direction perpendicular to the first axis, and the clamping member 132 can clamp one end of the ampoule bottle 200 away from the follower 121. Since the ampoule bottle 200 can adjust its angle, the clamping member 132 is rotated and its position is adjusted along the fourth direction to ensure that the clamping member 132 can correspond to the bottle mouth of the ampoule bottle 200.

[0059] Specific to Figure 3 In the illustrated embodiment, the fourth direction is the up-down direction. In practical applications, the fourth direction is the vertical direction.

[0060] In one embodiment, the clamping assembly 130 also includes a connecting member 133 and an adjusting rod 134, the connecting member 133 is rotatably connected to the bracket 131 around a third axis, the adjusting rod 134 is connected to the connecting member 133, the adjusting rod 134 is connected to the connecting member 133, the clamping member 132 is connected to the adjusting rod 134, and the adjusting rod 134 is reciprocatingly arranged along its axial direction so that the clamping member 132 can adjust its position along the fourth direction.

[0061] It is understandable that, in actual applications, the axial direction of the adjusting rod 134 is usually inclined relative to the horizontal direction, so when the adjusting rod 134 moves back and forth along its axial direction, the clamping member 132 connected to the adjusting rod 134 can adjust its position in the vertical direction.

[0062] Furthermore, the clamping assembly 130 also includes a clamp 135, which is connected to one end of the adjusting rod 134 close to the supporting assembly, and the clamping member 132 is movably connected to the clamp 135 so as to approach and move away from the supporting assembly during the movement, thereby approaching and moving away from the ampoule bottle 200 on the supporting assembly to ensure that the bottle mouth end of the ampoule bottle 200 is clamped.

[0063] It should be noted that the clamp 135 is provided with an adjustment screw, which can adjust the clamping force of the clamp 135, thereby facilitating the movement of the clamp 132. In addition, the clamp 132 includes a straight rod portion 1321 and a clamping portion 1322 connected to each other. The straight rod portion 1321 is connected to the clamp 135, and the straight rod portion 1321 can reciprocate along its own axis. The clamping portion 1322 is located at one end of the straight rod portion 1321 close to the support assembly. Figure 2 In the illustrated embodiment, the clamping portion 1322 is provided with a clamping hole that matches the bottle mouth end of the ampoule bottle 200. Of course, in other embodiments, the clamping portion 1322 may also be other forms to clamp the bottle mouth end of the ampoule bottle 200, such as a common spring clip.

[0064] In another embodiment, in order to adjust the position of the clamping member 132 along the fourth direction, the clamping member 132 can be connected to the top of the bracket 131, and the bracket 131 can be adjusted in length along the fourth direction. Figure 3 In the embodiment shown, the height of the bracket 131 can be adjusted in the vertical direction. It should be noted that the length can be adjusted by setting the bracket 131 to be composed of multiple hollow sections, which is similar to a fishing rod and will not be described in detail here.

[0065] Based on the positioning device in the above embodiment, the present application also provides a fuse device, which includes the positioning device in the above embodiment.

[0066] Furthermore, the fusing device further comprises a heating gun, which can heat the bottle mouth of the ampoule bottle 200 on the positioning device. Specifically, the heating gun is an oxyhydrogen flame spray gun.

[0067] In one embodiment, the fuse device further comprises a driving mechanism, which can drive the ampoule bottle 200 on the positioning device to rotate. In other embodiments, in order to reduce costs, the ampoule bottle 200 can also be rotated manually, which is not limited here.

[0068] In order to facilitate understanding of the technical solution of this application, Figure 1 The working process of the fuse device in the above embodiment is described as follows:

[0069] First, adjust the inclination angle of the first mounting plate 112 as needed. After the adjustment is completed, push the second mounting plate 122 close to the support assembly. After the second mounting plate 122 moves to the preset position, rotate the locking piece 124 so that the locking groove 1241 is buckled on the locking protrusion 125, and the second mounting plate 122 and the first mounting plate 112 are relatively fixed.

[0070] The ampoule bottle 200 is placed on a plurality of support members 113, and the bottom of the ampoule bottle 200 is in contact with the follower 121. Next, the mouth of the ampoule bottle 200 is heated by a heating gun. During the heating process, the ampoule bottle 200 can be rotated so that the mouth of the bottle is heated evenly. After heating to a certain degree, the clamping member 132 is clamped at the mouth of the ampoule bottle 200, and then the ampoule bottle 200 is continued to be rotated. Next, the mouth of the bottle continues to be heated and enters a soft-melting state, and then the mouth of the bottle is twisted and deformed during the rotation until the ampoule bottle 200 is sealed. The locking member 124 is rotated so that the locking member 124 is separated from the locking protrusion 125, and the ampoule bottle 200 slides downward with the second mounting plate 122 due to gravity, so that the body of the ampoule bottle 200 is separated from the mouth of the bottle. The second mounting plate 122 will be buffered by the buffer member 127 during the downward movement.

[0071] It should be noted that, in the above-mentioned embodiments, the structures movably connected to each other have movable damping between them, so that the two can move relative to each other when external force is applied, and can also remain relatively fixed after the external force is removed. For example, the first rod portion 1141 and the second rod portion 1142 of the adjusting member 114 can be hinged. When external force is applied, the angle between the first rod portion 1141 and the second rod portion 1142 can be adjusted to adjust the inclination angle of the first mounting plate 112. After the adjustment is completed, the external force is removed. At this time, the first rod portion 1141 and the second rod portion 1142 are fixed to each other due to the damping between them.

[0072] In addition, flexible pads may be provided at the positions contacting the ampoule 200, such as the surface of the support 113 and the surface of the follower 121, to avoid scratching the ampoule 200. Of course, the support 113 and the follower 121 may also be made of nylon or resin to protect the ampoule 200.

[0073] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
