Description

Technical Field

[0001] The invention relates to a heating tube processing device, in particular to an automatic production system for a high-temperature energy-saving semiconductor rapid heating glass tube. Background Art

[0002] The traditional heating tube uses a metal tube as the outer shell, and spiral electric heating alloy wire is evenly distributed along the central axis of the tube. It can be used directly after sealing. It only needs to be powered on when in use. Although it is cheap, its safety is relatively low. If leakage occurs, it will directly cause a major safety accident. In order to improve safety, superlattice electric heating film has been widely popularized. Superlattice electric heating film adopts a spraying method to spray a fluid mixture onto a designated area to form a superlattice electric heating film of the corresponding style, thereby realizing the heating and heat conduction of the carrier.

[0003] When the superlattice heating film is applied to a glass tube, it needs to be sprayed inside the glass tube to ensure that the outer wall of the glass tube does not leak electricity when heating water or other contact objects. In the traditional glass inner tube spraying process, a manual or semi-automatic method is usually adopted to insert the nozzle into the interior of the glass tube for spraying. It is only necessary to ensure that each surface is sprayed relatively evenly.

[0004] However, in the actual superlattice electric heating film spraying process, since the superlattice electric heating film needs to be sprayed in a high-temperature environment, the general processing environment is above 400°C, and human intervention is completely impossible. Workers not only have difficulty working in this environment, but once a mistake is made, a major accident will occur. Moreover, how to achieve mass production in such a high-temperature environment is also a major pain point in the industry. Often, only single-tube spraying, electrode welding, and cooling can be carried out, and production efficiency is relatively low.

[0005] This case aims to provide a high-temperature, energy-saving, semiconductor fast-heating glass tube automated production system, which can not only realize automated production without manual contact, but also completely rely on robots for automatic spraying during the spraying stage with accurate results, and can realize batch production. While realizing batch spraying, it can also simultaneously carry out other processes in other areas. Summary of the invention

[0026] The beneficial effects of the present invention are:

[0027] In the field of electric heating tubes where batch processing is difficult to achieve, the present invention proposes a complete unmanned and automated electric heating tube automatic production system. First, a loading robot is used to clamp the glass tube to be processed onto the loading transmission rack, and the loading transmission rack is used to perform lateral movement. The glass tube initially entering needs to be cleaned and dried by the cleaning unit to ensure that there is no dirt on the glass tube to avoid affecting the spraying effect of the glass tube. The cleaned glass tube can directly enter the spray unit and gradually heat up in the high-temperature spray chamber. At this time, the surface of the glass tube is already in an active state. The inner wall of the glass tube is then sprayed by the spray rod clamped on the spray robot. At the same time, during the spraying process, the power structure is used to drive the glass tube to rotate at all times, so that the spray rod can evenly spray the inner wall of the glass tube, so that the formed coating is uniform, and the temperature of each area is high after power is turned on. Similarly, to improve the thermal conductivity efficiency, after spraying is completed, the glass tube that has just been sprayed needs to be cooled so that the thermal conductive film can be quickly formed. The cooled and formed glass tube is clamped by the transfer unit and enters the silk-screen unit, and the positive and negative motors are also printed on the inner wall of the glass tube, so as to achieve the effect that the thermal conductive film can quickly conduct heat after the electrode is energized, and the glass tube after printing the electrode can be obtained as a finished product after secondary cooling by the second cooling unit. The finished glass tube can be directly unloaded to the subsequent inspection station through the unloading unit. During the entire processing process, no manual intervention is required, and no manual operation of the equipment is required. All operations are carried out in an automated state. Moreover, during spraying, several spray rods can be installed on the spray robot, and multiple glass tubes can be sprayed at the same time by multiple spray rods, thereby achieving the effect of spraying multiple tubes at the same time, and electric heating tubes can be automatically produced in batches under high temperature conditions.

[0028] In the actual processing process, the heating in the high-temperature spraying chamber cannot be completed in one go, but is a gradual process. Therefore, the present invention divides the high-temperature spraying chamber into at least two areas, one is a heating area and the other is a constant temperature area. The gradual heating process of the glass tube is completed in the heating area, and the spraying is completed in the constant temperature area.

[0029] In the prior art, since the spraying temperature is mostly 200-300°C, which is relatively low, there are more choices in terms of power. Compared with the spraying in this case, it is at a high temperature of 500-600°C, so the selection of its power structure is relatively difficult. In the present invention, the control component and the reversing seat are externalized, and the first mating fixture and the second mating fixture are extended to cooperate with the reversing seat, so that the power structure and the control structure are externalized, and the execution structure is inserted into the constant temperature zone, so that the execution structure can drive the glass tube to rotate without damaging the control component, the reversing seat and other power parts.

[0030] During the operation stage of the reversing seat, it not only has to drive the glass tube to rotate, but also has the function of lateral movement, so that it can restrain the glass tube after it moves to the specified position. Therefore, the reversing seat is equipped with a sliding motor that can slide on the guide shaft. At the same time, a first gear is fixed on its outer side, which can be driven to rotate by an external driving member, so that the first gear drives the first matching clamp and the second matching clamp to rotate, thereby realizing the effects of longitudinal power and lateral power.

[0031] In the process of the first matching fixture and the second matching fixture, the two focus on two different effects. Among them, the first matching fixture mainly has a fixing function, while the second matching fixture mainly plays a guiding role. The first matching fixture and the second matching fixture also have a rack and a gear that match the first gear, as well as a mounting seat for fixing the gear. However, in the setting of the chuck, there is a significant difference between the first mounting chuck and the second mounting chuck. In the setting process of the first mounting chuck, since it mainly has a clamping function, it is a bucket-shaped structure, and in contact with the glass tube During the process, the glass tube is tightly clamped with rigid contact. On the other side of the glass tube, if direct clamping is also adopted, the rigid contact at both ends may easily damage the glass tube. Therefore, a directional plate abutment method is adopted in the second mounting chuck to hold the glass tube, so that the abutting head on the first mounting chuck has a force point. At the same time, a plurality of arc-shaped clip groups are used to clamp the glass tube tightly, so that it is not easy to change direction during the rotation process. Then, when spraying, the position of the spray rod is always equidistant from the glass tube, thereby ensuring the uniformity of the spraying.

[0032] Although the power structure and the execution structure are completely isolated into two areas due to the arrangement of the first mating fixture and the second mating fixture, since they are both metal structural parts, they are extremely easy to conduct heat, so there is still a certain probability that the reversing seat will be damaged. In this regard, the present invention further proposes to set a cooling device at the bottom of the constant temperature zone, and use the cooling device to cool the first rack and the second rack extending downward, thereby reducing the heat transmitted to the second gear and the third gear, so that the driving structure and the sliding motor of the second gear and the third gear can be better temperature avoided. Even if there is a certain temperature residue, it is still within their tolerance range.

[0033] The above-mentioned regularizes the error phenomenon that may occur in the lateral movement and rotation of the glass tube, but still does not take into account the precision error phenomenon that may occur in the movement of the spray rod. The above-mentioned improvement is that the present invention uses multi-tube spraying, and the entire spray rod needs to extend into the interior of the entire glass tube during the spraying process. Therefore, the actual length of the spray rod is very long and the span is long. However, at the same time, the straightness of the spray rod directly affects the quality of the entire glass tube. For this reason, the present invention sets a correction structure near the middle section of the spray rod, wherein the correction structure is divided into two parts:

[0034] One part is the far-end detection, which is detected at the far-end through the far-end detection structure. Once the spray rod is offset when it is extended to the far end, the far-end detection structure will be triggered immediately. If the spray rod is always in a straight extended state, the far-end detection structure will never be triggered. The other part is the near-end correction structure. When the far-end detection structure detects an abnormal state, the abnormal state will be immediately fed back to the trigger rod through a mechanical triggering method, and then fed back to the near-end correction structure through the trigger rod. If an error occurs in the far-end detection structure at the corresponding position, the trigger rod at the corresponding position will trigger the near-end correction structure at the corresponding position, so that the near-end correction structure can immediately correct the spray rod in the corresponding direction, so that it can immediately respond and adjust the direction. After a processing cycle, the spray rod can be replaced immediately, thereby avoiding uneven spraying of the entire batch of glass tubes and meeting the design requirements under high temperature environments.

[0052] Among them, Figure 1 It can be seen that the transfer unit 50 and the unloading unit 80 are both robot structures, and the programming logic and actions of the robots are all existing technologies and will not be described in detail here.

[0053] As for the screen printing unit 60 in this embodiment, since it is not the key structure of this case, it can be regarded as the prior art and can be understood by referring to the principle of the existing screen printing electrode.

[0054] In this embodiment, the first cooling unit 40 and the second cooling unit 70 are both divided into two steps, namely, cooling liquid spraying and a rear air cooling structure, so that the glass tube at high temperature can be quickly cooled and quickly enter the next process.

[0055] The specific use principle of the present invention is as follows: in the field of electric heating tubes that are difficult to achieve batch processing, the present invention proposes a complete unmanned and automated electric heating tube automatic production system. First, the upper piece manipulator 11 is used to clamp the glass tube to be processed onto the upper piece transmission rack 12, and the upper piece transmission rack 12 is used to perform lateral movement. The glass tube initially entering needs to be cleaned and dried by the cleaning unit 20 to ensure that there is no dirt on the glass tube to avoid affecting the spraying effect of the glass tube. The cleaned glass tube can directly enter the spray unit 30, and gradually heat up in the high-temperature spray chamber 31. At this time, the surface of the glass tube is already in an active state, and then the inner wall of the glass tube is sprayed by the spray rod 34 clamped on the spray robot 33. At the same time, during the spraying process, the power structure 32 is used to drive the glass tube to rotate at all times, so that the spray rod 34 can evenly spray the inner wall of the glass tube, so that the formed coating is uniform, and when power is turned on Afterwards, the temperature of each area is the same, which improves the thermal conductivity efficiency. After spraying, the glass tube that has just been sprayed needs to be cooled so that the thermal conductive film can be quickly formed. The cooled and formed glass tube is clamped by the transfer unit 50 and enters the screen printing unit 60, and the positive and negative motors are also printed on the inner wall of the glass tube, so as to achieve the effect that the thermal conductive film can quickly conduct heat after the electrode is energized. The glass tube after printing the electrode can be obtained as a finished product after secondary cooling by the second cooling unit 70. The finished glass tube can be directly unloaded to the subsequent inspection station through the unloading unit 80. During the entire processing process, no manual intervention is required, and no manual operation of the equipment is required. All operations are carried out in an automated state. Moreover, during spraying, a plurality of spray rods 34 can be installed on the spray robot 33, and multiple glass tubes can be sprayed simultaneously by multiple spray rods 34, so as to achieve the effect of spraying multiple tubes at the same time, and electric heating tubes can be automatically produced in batches under high temperature conditions.

[0056] In this embodiment, the spraying robot 33 can act on four spraying rods 34 at the same time, and can spray four glass tubes at the same time.

[0057] In the actual processing process, the heating in the high-temperature spraying chamber 31 cannot be achieved in one go, but is a gradual process. Therefore, the present invention divides the high-temperature spraying chamber 31 into at least two areas, one is a heating zone 3A, and the other is a constant temperature zone 3B. The gradual heating process of the glass tube is completed in the heating zone 3A, and the spraying is completed in the constant temperature zone 3B. In fact, in this embodiment, there are at least two heating zones 3A and more than two constant temperature zones 3B to achieve the effect of gradual heating and heat preservation after spraying.

[0058] In the prior art, since the spraying temperature is mostly 200-300°C, which is relatively low, there are more choices in terms of power. Compared with the spraying in this case, it is at a high temperature of 500-600°C, so the selection of its power structure is relatively difficult. In the present invention, the constant temperature zone 3B includes a constant temperature chamber 311 for accommodating the glass tube, and the power structure 32 is arranged at the bottom of the constant temperature chamber 311. The power structure 32 includes a control component 321 fixedly connected to the bottom of the constant temperature chamber 311, a guide shaft 322 meshed with the control component 321, two reversing seats 323 slidably arranged on the guide shaft 322, and the two reversing seats 323 are connected and sleeved on the The first matching clamp 324 and the second matching clamp 325 on both sides of the glass tube are clamped on both sides of the glass tube after the reversing seat 323 slides, and the first matching clamp 324 and the second matching clamp 325 drive the glass tube to rotate after the reversing seat 323 rotates. The control component 321 and the reversing seat 323 are placed outside, and the first matching clamp 324 and the second matching clamp 325 are extended to cooperate with the reversing seat 323, so that the power structure and the control structure are placed outside, and the execution structure is inserted into the constant temperature zone 3B, so that the execution structure can drive the glass tube to rotate without damaging the power parts such as the control component 321 and the reversing seat 323.

[0059] During the operation stage of the reversing seat 323, it not only has to drive the glass tube to rotate, but also has the function of lateral movement, so that it can restrain the glass tube after it moves to the specified position. Specifically, the reversing seat 323 includes a sliding motor 3231 matched with the guide shaft 322, and a first gear 3232 connected to the outer side of the sliding motor 3231 through a bearing. The two first gears 3232 are respectively engaged with the first matching fixture 324 and the second matching fixture 325. The reversing seat 323 is provided with a sliding motor 3231 that can slide on the guide shaft 322. At the same time, a first gear 3232 is also fixed on the outer side thereof, and the first gear 3232 can be driven to rotate by an external driving member, so that the first gear 3232 drives the first matching fixture 324 and the second matching fixture 325 to rotate, thereby realizing the effects of longitudinal power and lateral power.

[0060] In the process of the first mating fixture 324 and the second mating fixture 325, the two focus on two different effects, wherein the first mating fixture 324 mainly plays a fixing role, while the second mating fixture 325 mainly plays a guiding role. The specific structures of the first mating fixture 324 and the second mating fixture 325 are as follows: the first mating fixture 324 includes a first rack 3241 mating with the first gear 3232, a second gear 3242 meshing with the first rack 3241, a first mounting seat 3243 fixing the second gear 3242, and a first mounting seat 3243 arranged in the second gear 3242 and used for fixing the second gear 3242. A first mounting chuck 3244 sleeved on one side of the glass tube, a pressing head 3245 is provided on one side of the first mounting chuck 3244 close to the glass tube, the second matching fixture 325 includes a second rack 3251 matched with the first gear 3232 on the other side, a third gear 3252 meshed with the second rack 3251, a second mounting seat 3253 fixing the third gear 3252, a second mounting chuck 3254 provided in the third gear 3252 and sleeved on the other side of the glass tube, and an orienting plate 325 welded on the second mounting chuck 3254 5. The directional plate 3255 is provided with a plurality of arc-shaped clip groups 3256, and the gap between the arc-shaped clip groups 3256 is equal to the wall thickness of the glass tube. From the above, it can be seen that the first matching fixture 324 and the second matching fixture 325 are also provided with a rack and a gear matched with the first gear 3232, and a mounting seat for fixing the gear. However, in terms of the setting of the chuck, the first mounting chuck 3244 and the second mounting chuck 3254 are obviously different. In the setting process of the first mounting chuck 3244, due to its main clamping function, it is a bucket-shaped structure, and in the contact process with the glass tube, The glass tube is tightly clamped by rigid contact in the middle, and if the direct clamping method is also adopted on the other side of the glass tube, the rigid contact at both ends may easily damage the glass tube. Therefore, the second mounting chuck 3254 adopts the method of abutting with the directional plate 3255 to hold the glass tube, so that the pressing head 3245 on the first mounting chuck 3244 has a force point, and at the same time, a plurality of arc-shaped clip groups 3256 are used to clamp the glass tube tightly, so that it is not easy to change direction during the rotation process, and then the position of the spray rod 34 is always equidistant from the glass tube during spraying, thereby ensuring the uniformity of the spraying.

[0061] In fact, there is no fixed structure on the outside of the first rack 3241 and the second rack 3251. However, as can be seen from the figure, a U-shaped clamp is provided on the outside of the first mounting seat 3243 and the second mounting seat 3253, which can restrain the first rack 3241 and the second rack 3251 through the U-shaped clamp so that they can remain engaged with the second gear 3242 and the third gear 3252, and at the same time, the U-shaped clamp can slide along with the sliding of the first mounting seat 3243 and the second mounting seat 3253. The power of the first mounting seat 3243 and the second mounting seat 3253 comes from the sliding motor 3231.

[0062] Although the power structure and the execution structure are completely isolated into two areas due to the arrangement of the first matching fixture 324 and the second matching fixture 325, since they are all metal structural parts, they are extremely easy to conduct heat, so there is still a certain probability that the reversing seat 323 will be damaged. In this regard, the present invention further proposes to arrange a cooling device 312 at the bottom of the constant temperature zone 3B, and the cooling device 312 includes an annular groove 3121 for accommodating the first rack 3241 and the second rack 3251, a cooling chute 3122 sleeved on the outside of the annular groove 3121, a circulation belt 3123 connected to the cooling chute 3122, and a circulation groove 3124 identical to the circulation belt 3123. The circulation belt 3123 surrounds the guide shaft 322. The top of the fixed brackets on both sides cools down the first rack 3241 and the second rack 3251 extending downward through the cooling device 312, thereby reducing the heat transmitted to the second gear 3242 and the third gear 3252, so that the driving structure of the second gear 3242 and the third gear 3252 and the sliding motor 3231 can be better temperature-avoided. Even if there is a certain temperature residue, it is within their tolerance range. It should be emphasized that the bottom of the first mounting seat 3243 and the second mounting seat 3253 are provided with a clamping plate, which can slide with the gap of its own sliding sealer, so as to avoid the first mating fixture 324 and the second mating fixture 325 from leaking heat when sliding, causing energy waste.

[0063] The above-mentioned regulation of the error phenomenon that may occur in the lateral movement and rotation of the glass tube, but still does not take into account the precision error phenomenon that may occur in the movement of the spray rod 34. The above-mentioned improvement is that the present invention is multi-tube spraying, and the entire spray rod 34 needs to be extended into the interior of the entire glass tube during the spraying process. Therefore, the actual length of the spray rod 34 is very long and the span is long. However, at the same time, the straightness of the spray rod 34 directly affects the quality of the entire glass tube. In this regard, the present invention is close to the spray rod 34. A correction structure 35 is provided at the middle position, and the correction structure 35 includes a distal detection structure 351 provided on the inner wall of the constant temperature zone 3B, and a proximal correction structure 352 provided on the outer wall of the constant temperature zone 3B, and a trigger rod 353 connected between the distal detection structure 351 and the proximal correction structure 352. After the distal detection structure 351 is acted upon by the spraying rod 34, the trigger rod 353 triggers the proximal correction structure 352 to correct the spraying rod 34. The correction structure 35 is divided into two parts:

[0064] One part is for detection at the far end. The far end detection structure 351 includes an inner clamping seat 3511 locked on the inner side wall of the constant temperature zone 3B, a first through hole 3512 opened at the axial center of the inner clamping seat 3511, a guide seat 3514 slidably arranged on the inner side of the inner clamping seat 3511 and connected to the inclined surface of the trigger rod 353 through a spring 3513, and a guiding inclined surface 3515 is provided on the side of the guide seat 3514 facing the spray robot 33. The detection is performed at the far end through the far end detection structure 351. Once the spray rod 34 is offset when extending to the far end, the far end detection structure 351 will be immediately triggered. If the spray rod 34 is always in a straight extension state, the far end detection structure 351 will never be triggered.

[0065] The other part is a proximal correction structure 352, which includes an outer mounting seat 3521 connected to the outer side wall of the constant temperature zone 3B, a second through hole 3522 provided in the axial center of the outer mounting seat 3521, a trigger seat 3523 installed on the outer mounting seat 3521 and corresponding to the end of the trigger rod 353, a plurality of correction tables 3524 arranged on the inner side of the outer mounting seat 3521, and a push rod motor 3525 connected to the correction table 3524. A piezoelectric sheet 3526 is provided on the inner side of the trigger seat 3523, and the piezoelectric sheet 3526 is electrically connected to the push rod motor 3525. When 51 detects an abnormal state, it will immediately feed back the abnormal state to the trigger rod 353 through a mechanical triggering method, and then feed back to the proximal correction structure 352 through the trigger rod 353. If an error occurs in the far-end detection structure 351 at the corresponding position, the proximal correction structure 352 at the corresponding position will be triggered through the trigger rod 353 at the corresponding position, so that the proximal correction structure 352 can immediately correct the spray rod 34 in the corresponding direction, so that it can immediately respond and adjust the direction. After a processing cycle, the spray rod 34 can be replaced immediately, thereby avoiding uneven spraying of the entire batch of glass tubes and meeting the design requirements in a high temperature environment.

[0066] In fact, the proximal correction structure 352 having the piezoelectric sheet 3526 and the push rod motor 3525 is arranged on the outer wall of the constant temperature zone 3B so as not to be affected by the high temperature in the constant temperature zone 3B.

[0067] Embodiment 2

[0068] The difference between this embodiment and the first embodiment is that the glass tube processed in this embodiment is in a state where both ends are open, that is, a hollow cylindrical tube with both ends open.

[0069] And precisely because of the openings at both ends, during the entire production system design process, the R&D personnel adopted the auxiliary support effect on the other end of the spray rod 34, so that it can have a certain supporting auxiliary effect during the long-term and long-distance extension spraying process, so that it can be used for a long time without deformation. In this embodiment, specifically: it also includes a reverse auxiliary structure 90, the reverse auxiliary structure 90 includes a mounting pile 91 locked with the inner wall of the constant temperature chamber 311, an air pump 92 located outside the high-temperature spray chamber 31 and connected to the inner side of the mounting pile 91, a fixed shaft 93 locked in the mounting pile 91 and with the same pipeline as the air pump 92, a movable shaft 94 slidably sleeved on the outer wall of the fixed shaft 93, a bearing 95 opened at the bottom of the movable shaft 94, and a support cover 96 welded on the bearing of the bearing 95, and the support cover 96 is fitted with the arc head at the end of the spray rod 34.

[0070] Among them, the spray rod 34 is pushed into the interior of the glass tube under the action of the spray robot 33. At the same time, the air pump 92 inflates the hollow fixed shaft 93, allowing the high-pressure gas to rush out from the opening at the bottom of the fixed shaft 93, pushing the movable shaft 94 outward, thereby pushing the movable shaft 94 out and extending to the inner wall of the glass tube. The supporting cover 96 at the bottom supports the arc-shaped head at the end of the spray rod 34, supporting the entire spray rod 34 to prevent it from tilting and deforming easily.

[0071] In this embodiment, ribs are provided at the matching positions of the fixed shaft 93 and the movable shaft 94 to guide the relative movement therebetween. Since airtightness needs to be maintained during the overall movement, a high-temperature and over-pressure inlaid sealing material H800 is provided on the outside of the ribs. The high-temperature and over-pressure inlaid sealing material H800 can withstand high temperatures above 800°C and is not easily deformed even at a high temperature of 600°C.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
