Description

Technical Field

[0001] The invention relates to the technical field of lamp tube processing equipment, in particular to an ultraviolet lamp tube linkage tube baking machine. Background Art

[0002] Lamp tube baking machines are mainly used for the tube baking process in the production process of fluorescent lamps, energy-saving lamps and other lamp tubes. In the process of coating the fluorescent powder on the lamp tube, some adhesives or other impurities will remain in the lamp tube. In the production process of the lamp tube, a layer of chemical protective film will also be covered on the surface of the lamp tube. Therefore, the tube baking machine carbonizes and blows away these residues inside the lamp tube through high-temperature heating and blowing, and melts and removes the chemical protective film on the outside of the lamp tube through high temperature, while solidifying the fluorescent powder to ensure the quality and performance of the lamp tube. At present, most of the tube baking machines on the market achieve uniform baking of the lamp tube by rotating the lamp tube during the production process. This way of rotating the lamp tube makes the structure of the tube baking machine complicated, and different parts of the lamp tube may not be baked at the same temperature during the entire rotation process. Therefore, not only is the cost high, but the quality of the finished product is also unstable.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN202321143099.1, patent name: a tube baking machine) is: first, insert the energy-saving lamp into the top surface of the placement table, insert the mounting frame on the bottom surface of the placement table into the mounting groove on the surface of the conveyor belt, start the electric telescopic rod to adjust the position of the limit frame, so as to limit the placement table, rotate the screw rod to make the rack on the top surface of the adjusting rod mesh with the gear ring, start the conveyor to drive the placement table to rotate, and at the same time start the heating tube to bake the energy-saving lamp at high temperature, which can increase the heating area of ​​the energy-saving lamp, thereby improving work efficiency, and the inside of the shell is installed The installed fan can remove dust and other debris on the surface of the energy-saving lamp, thereby preventing the debris from attaching and affecting the quality of the energy-saving lamp. The installed temperature sensor can detect the temperature inside the baking shell, thereby maintaining the inside of the baking shell at a suitable temperature, and activate the alarm light to remind personnel to check when the temperature changes too much. The handle is convenient for taking the placement table, and the rubber sleeve can prevent people's hands from being burned by high temperature. Finally, the spring rod shrinks and rebounds to insert the plug on the rear side of the connecting plate into the slot on the front side of the casing, thereby facilitating the fixation of the baking shell and also facilitating the opening of the baking shell for subsequent maintenance.

[0004] From the above implementation scheme and the corresponding drawings, it can be seen that the tube baking machine allows different parts of the lamp tube to be baked by the heat source by rotating the lamp tube during the baking process. However, this does not allow every part of the lamp tube to be baked at the same temperature and for the same time. In order to bake the lamp tube more evenly, it takes longer time to rotate the lamp tube for baking. Therefore, not only does it increase the production cost, it may also cause unstable quality of the finished product. Summary of the invention

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] like Figures 1 to 15 As shown, a UV lamp linked tube baking machine includes a tube baking assembly 1, which includes a first thermal insulation cotton 106, a cover body 107 is arranged above the first thermal insulation cotton 106, and a second thermal insulation cotton 1072 is arranged inside the cover body 107; the cover body 107 can be raised and lowered, and the horizontal projection area of ​​the cover body 107 is smaller than the area of ​​the first thermal insulation cotton 106. When the cover body 107 descends and covers the first thermal insulation cotton 106, a closed baking space is formed between the cover body 107 and the first thermal insulation cotton 106; because the horizontal projection area of ​​the cover body 107 is smaller than the area of ​​the first thermal insulation cotton 106, the two can achieve better insulation and sealing effects when they are covered, so that the temperature of each position inside the baking space is uniform, thereby forming a better baking effect for the lamp tube, and in addition, the first thermal insulation cotton 106 and the second thermal insulation cotton 1072 can maintain the temperature inside the baking space to prevent heat from dissipating, thereby reducing the working intensity of the heat source.

[0022] The first thermal insulation cotton 106 is connected to the gas delivery rack 104; a heat source is arranged inside the roasting space, and after the lamp tube to be roasted is placed inside the roasting space, the heat source generates heat, and the gas delivery rack 104 blows gas into the lamp tube, and the impurities on the outer wall and the inner wall of the lamp tube are degraded and blown away. The lamp tube is placed in the roasting space for high-temperature roasting, and gas is supplied to the lamp tube through the gas delivery rack 104. The gas input by the gas delivery rack can accelerate the reaction of impurities on the surface of the lamp tube. In this embodiment, the gas input by the gas delivery rack 104 is oxygen, and these gases can also blow away the reactants of the impurities, so that the quality of lamp tube processing is more stable.

[0023] One side of the baking tube component 1 is provided with a placement component 2, a merging and pushing component 3, a conversion component 4 and a single conveying system 5 in sequence; because the lamp tubes need to be processed individually in the previous process, the single conveying system 5 is used to transfer the lamp tubes from the previous process, and when the lamp tubes are transported in the single conveying system 5, there is a gap between every two lamp tubes, and the conversion component 4 is used to transfer the lamp tubes from the single conveying system 5 to the merging and pushing component 3. After the lamp tubes are transported to the merging and pushing component 3, the lamp tubes are arranged closely together; it is convenient for the placement component 2 to take multiple lamp tubes at the same time, and the placement component 2 is used to send several lamp tubes from the merging and pushing component 3 to the baking tube component 1, so the entire conveying process can be automated, without the need for manual participation, which greatly improves production efficiency.

[0024] The grill tube assembly 1 includes a frame 101, a cover 107 is slidably connected to the frame 101, and the frame 101 is also connected to a cover lifting power component 105; the frame 101 includes a vertical slide bar 1011, and a side pulley 1071 is arranged on the outer side of the cover 107, and the side pulley 1071 is rollingly connected to the slide bar 1011. The side pulley 1071 not only enables the cover 107 to slide relative to the frame 101, but also limits the front, back, left, and right positions of the cover 107 in the frame 101, so that the cover When the cover 107 moves in the frame 101, the body 107 will not shake forward, backward, left or right. A limit latch 102 is also provided in the middle section of the frame 101. When the operator needs to repair the baking tube assembly 1, after lifting the cover 107, the latch 102 can be pushed under the cover 107, so that the latch 102 can resist the bottom of the cover 107, avoiding the operator's body from being hit by the descending cover 107. Therefore, the latch 102 plays a role of safety protection, and the latch 12 has a simple structure and low cost.

[0025] A reaction guard 103 is arranged on the first heat-insulating cotton 106, and a gas delivery frame 104 is located at one end of the reaction guard 103. The gas delivery frame 104 includes an air inlet 1041 and an air outlet 1042. When the cover 107 is covered on the first heat-insulating cotton 106, the air inlet 1041 is outside the roasting space, and the air outlet 1042 is inside the roasting space. After the placement and removal component grabs the lamp tube from the merging and pushing component 3, the lamp tube is placed on the reaction guard 103; The placement assembly 2 includes a cross arm module 201, on which a first pick-and-place robot 202 and a second pick-and-place robot 203 are movably connected; the first pick-and-place robot 202 and the second pick-and-place robot 203 can move on the cross arm module 201, so the distance between the first pick-and-place robot 202 and the second pick-and-place robot 203 can be adjusted according to the length of the lamp tube.

[0026] The first pick-and-place robot 202 includes a first Z-axis module 2021, which is connected to a first Y-axis module 2022, and the first Y-axis module 2022 is connected to a first pick-and-place tray 2023; the second pick-and-place robot 203 includes a second Z-axis module 2031, which is connected to a second Y-axis module 2032, and the second Y-axis module 2032 is connected to a second pick-and-place tray 2033. The first pick-and-place tray 2023 and the second pick-and-place tray 2033 are arranged opposite to each other. When taking the lamp tube, the first pick-and-place tray 2023 and the second pick-and-place tray 2033 lift the lamp tube from under both ends of the lamp tube, and then transfer it to the reaction rack 103. At this time, the lamp tube is located in the middle of the reaction rack 103. The first pick-and-place tray 2023 first withdraws from the baking tube assembly 1 under the drive of the second Y-axis module 2032, and then the second pick-and-place tray 2033 presses against one end of the lamp tube and pushes the lamp tube toward the gas delivery rack 104, so that one end of the lamp tube is inserted into the gas outlet 1042, so that the gas is discharged from the gas outlet 1042. 42 can enter the interior of the lamp tube when it is output, and the air outlet 1042 can also be smoothly inserted into the lamp tube, and the gas delivery rack 104 plays a role of limiting the lamp tube. The width of the lamp tubes taken by the placement and retrieval component 2 each time can just be placed in the width direction of the gas delivery rack 104. Therefore, after the lamp tubes are placed in the gas delivery rack 104, the axial position of each lamp tube and the axial position of the corresponding air outlet 1042 are in corresponding positions, and the circumference of the air outlet 1042 is less than one-third of the inner diameter of the lamp tube. In this way, even if the lamp tubes are stacked, the axis of the lamp tube is not on the same axis as the axis of the air outlet 1042.

[0027] After the second pick-and-place tray 2033 docks the lamp tube with the air outlet 1042, it also withdraws from the baking tube assembly 1, and then the first pick-and-place tray 2023 and the second pick-and-place tray 2033 continue to take the next group of lamp tubes. Each group of lamp tubes is stacked on the gas delivery rack 104. Since the temperature inside the baking space is uniform, the lamp tubes can be repeatedly baked even though they are stacked together. In this way, the number of lamp tubes processed each time is greater than the traditional method of rotating the lamp tubes to bake, thereby improving production efficiency.

[0028] The cover lifting power component 105 includes a winding wheel 1052, a first positioning wheel 1053 and a second positioning wheel 1055. The first positioning wheel 1053 is located on the side of the frame 101, and the second positioning wheel 1055 is located on the top of the frame 101. The winding wheel 1052 is wound with a lifting rope 1054, and the lifting rope 1054 passes over the first positioning wheel 1053 and the second positioning wheel 1055 and then is connected to the cover 107; the winding wheel 1052 is connected to the motor 1051, and the motor 1051 drives the winding wheel 1052 to rotate. The winding wheel 1052 rotates to realize the retraction and extension of the lifting rope 1054, thereby pulling the cover 107 to lift and lower.

[0029] The merging and pushing component 3 is provided with a merging and pushing belt 301, and a stopper 302 is provided at one end of the merging and pushing belt 301 close to the baking tube component 1. After the lamp tube is placed on the merging and pushing belt 301 by the conversion component 4, the merging and pushing belt 301 rotates to push the lamp tube toward the baking tube component 1, and the lamp tube is finally closely arranged together by the stopper 302 and waits to be taken by the placement and removal component 2.

[0030] The width of the combined pushing component 3 and the single conveying system 5 are both smaller than the length of the lamp tube, so that both ends of the lamp tube will be exposed on both sides of the machine, making it convenient for the conversion component 4 and the placement component 2 to take the two ends of the lamp tube.

[0031] The conversion component 4 includes a connecting shaft 402, both ends of which are connected to a turntable 401, and end clamps 403 are arranged along the circumferential direction of the turntable 401; when the turntable 401 rotates, the end clamps 403 of the turntable 401 close to one end of the single conveying system 5 clamps the lamp tube located at the end of the single conveying system 5, and as the turntable 401 rotates, the lamp tube is driven upward until it reaches the merging and pushing belt 301, and as the lamp tube contacts the merging and pushing belt 301, the end clamps 403 release the lamp tube, and the lamp tube is taken away by the merging and pushing belt 301, because a plurality of end clamps 403 are arranged in the circumferential direction of the turntable 401, as the turntable 401 rotates, the end clamps 403 at one end of the turntable 401 clamps the lamp tube, and the end clamps 403 at the other end release the lamp tube, so that a plurality of lamp tubes can be driven to transfer at the same time, thereby improving production efficiency.

[0032] The end clamping member 403 includes a pushing and clamping cylinder 4031, which is connected to a supporting clamp 4035, and a spring 4037 is provided between the supporting clamp 4035 and the pushing and clamping cylinder 4031; therefore, when the supporting clamp 4035 clamps the lamp tube from both ends of the lamp tube, no strong collision will be generated on the lamp tube, thus preventing the supporting clamp 4035 from damaging the lamp tube due to collision. The supporting clamp 4035 is V-shaped, so that the supporting clamp 4035 can support lamp tubes of different outer diameters.

[0033] The output end of the push-clamp cylinder 4031 is connected to the seat bearing 4032, the seat bearing 4032 is connected to the gravity seat 4033, and the lower end of the gravity seat 4033 is connected to the counterweight ball 4038; therefore, no matter what position the turntable 401 rotates to, the lower end of the gravity seat 4033 falls due to the gravity of the counterweight ball 4038, thereby ensuring that the lamp tube is always above the gravity seat 4033, so that the lamp tube can be better supported by the gravity seat 4033.

[0034] The gravity seat 4033 is connected to the spring seat 4034, and a sliding shaft 4036 is provided in the spring seat 4034. The spring 4037 is plugged into the sliding shaft 4036, and the supporting clip 4035 is slidably plugged into the sliding shaft 4036. One end of the spring 4037 abuts against the supporting clip 4035, and the other end abuts against the inner side of the spring seat 4034; the spring 4037 always pushes the supporting clip 4035 toward the lamp tube, so that the supporting clips 4035 on both sides of the lamp tube can not only support the lamp tube, but also clamp the two ends of the lamp tube, so that the lamp tube can be transported. The delivery is more stable. Under the thrust of the pushing and clamping cylinder 4031, the supporting clamp 4035 clamps the lamp tube from both ends of the lamp tube. Under the gravity of the counterweight ball 4038, the V-shaped supporting plate of the supporting clamp 4035 is always at the lower side of the lamp tube, thereby ensuring that the lamp tube is firmly clamped. Because of the existence of the spring 4037, although the lamp tube may have a certain deviation in length due to errors during processing, the lamp tube will not be damaged due to collision when being clamped, so the lamp tube can be safely transported.

[0035] One end of the coupling 402 is connected to a passive pulley 404, the passive pulley 404 is connected to a belt 405, the other end of the belt 405 is connected to a driving pulley, the driving pulley is connected to a coupling drive motor 406, and the coupling drive motor 406 drives the coupling 402 to rotate, thereby rotating the turntable 401.

[0036] A single conveying system 5 includes a chain 501, which connects a plurality of chain links 502. A support piece 503 is inserted on the chain link 502. The support piece 503 is a circular rubber piece. Therefore, when the support piece 503 contacts the lamp tube, no rigid collision will occur on the lamp tube, which is beneficial to protect the lamp tube from being broken. On the other hand, the friction between the rubber material and the glass material of the lamp tube is greater than the friction between the metal material and the glass material, which is beneficial to the lamp tube being more stably fixed between the two support pieces 503.

[0037] The center of the support piece 503 coincides with the chain link 502; viewed from the axial direction of the chain link 502, a V-shaped support angle is formed between the support pieces 503 of two adjacent chain links 502, and the lamp tube being transported is located on the V-shaped support angle, so lamp tubes of different outer diameters can be placed on the V-shaped support angle, making the adaptability of a single conveying system 5 wider.

[0038] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
