Description

Technical Field

[0001] The present invention belongs to the technical field of glass tube processing, and more specifically, relates to a glass tube micro-drilling device. Background Art

[0002] In the glass bottle manufacturing process, glass tubes are key raw materials. By finely processing the glass tubes, glass bottles are finally made. During the manufacturing process of ampoules, it is necessary to drill holes in the side of the glass tube near one end. This step is crucial because in the subsequent melting process, if the gas inside the glass tube expands due to high temperature, the glass tube without pre-drilled holes will burst due to a sharp increase in internal pressure, resulting in material waste and production accidents.

[0003] Currently, the glass tube drilling operation usually adopts a one-by-one processing method, that is, using a drilling lamp head on the production line to drill holes in the side walls of each glass tube in turn. However, this method has many drawbacks: 1) Uneven drilling; due to one-by-one operation, it is difficult to ensure the consistency of the drilling position and hole diameter of each glass tube, resulting in uneven product quality; 2) Low efficiency; the one-by-one drilling method severely limits the production efficiency and is difficult to meet the needs of large-scale production; 3) High scrap rate; if the drilling time is not properly controlled, too long or too short, and the drilling hole diameter does not meet the requirements, a large number of defective products will appear, increasing the production cost. Summary of the Invention

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Please refer to Figures 1 to 6 , and now the glass tube micro-drilling device provided by the present invention will be described. The glass tube micro-drilling device includes a synchronous following component 1, a lifting component 2 and a drilling component 3. The synchronous following component 1 is arranged on the side of the glass tube production line and has a mobile end with a degree of freedom of moving along the glass tube transportation direction. The mobile end is used to intermittently synchronously follow the movement of the glass tube production line; the lifting component 2 is connected to the mobile end of the synchronous following component 1. The lifting component 2 has a lifting block 21 with a degree of freedom of moving in the vertical direction. The lifting block 21 is adapted to simultaneously drive a plurality of adjacent glass tubes on the glass tube production line to rise or fall; the drilling component 3 is connected to the mobile end of the synchronous following component 1. The drilling component 3 has a plurality of drilling lamp heads 31 with a degree of freedom of moving in the vertical direction. The plurality of drilling lamp heads 31 are adapted to simultaneously heat and drill the sides of a plurality of glass tubes after being lifted by the lifting block 21; wherein, before drilling a plurality of glass tubes, the synchronous following component 1 moves intermittently with the glass tubes. During the movement, the lifting component 2 is used to lift one end of a plurality of glass tubes (the glass tubes are relatively long and are in a slightly inclined state after being lifted, which does not affect the drilling requirements), and the drilling component 3 is used to simultaneously heat and drill a plurality of glass tubes.

[0021] Compared with the prior art, the glass tube micro-drilling device provided by the present invention has a synchronous following component 1 that can intermittently follow the movement of the glass tube production line. Through the lifting component 2, one end of multiple glass tubes can be pushed up simultaneously during the movement. By using the drilling component 3, the lifted glass tubes can be heated and drilled simultaneously. After drilling, the drilling component 3 stops, the lifting component 2 retracts, and the glass tubes are lowered to the glass tube production line, thus completing a cycle. Then, the following component can be used again to follow the production line, the lifting component 2 can be used to lift multiple glass tubes close to the drilled glass tubes, and the drilling component 3 can be used to drill holes. By repeating such operations, the continuous drilling operation of multiple glass tubes can be completed, which can accelerate the micro-drilling progress and drilling efficiency of the glass tubes. The drilling diameter is uniform and consistent, the drilling positions are consistent, and the rejection rate is significantly reduced.

[0022] In the present invention, the drilling flame length and burning time of the drilling lamp head 31 can be set and adjusted to ensure successful drilling at one time. The synchronous following component 1, the lifting component 2, and the drilling component 3 in the present invention are electrically connected to each other to form a system, which cooperate with each other for processing or operation. The moving speed of the synchronous following component 1 is consistent with the speed of the glass tube production line (hereinafter referred to as the production line), and its speed can be adjusted and controlled to achieve synchronous movement. The synchronous following component 1 moves intermittently. During the movement, the lifting component 2 lifts multiple glass tubes, and the drilling component 3 can complete the drilling process of the glass tubes. After completing one drilling operation, the lifting component 2 and the drilling component 3 are reset, and then the synchronous following component 1 moves a certain distance in the opposite direction of the production line (this distance is the total length formed by the multiple glass tubes lifted by the lifting component 2 at one time and can be regarded as a stroke). At this time, the synchronous following component 1 can be made to continue following the production line again. At this time, the lifting component 2 can be used again to lift multiple glass tubes in the next cycle, and then the drilling component 3 can be used to drill the lifted multiple glass tubes. After drilling, the drilling component 3 and the lifting component 2 are reset. At this time, the second cycle is completed. Continuing this operation mode in the future, multiple cycles can be completed, and multiple glass tubes on the production line can be drilled one after another. Compared with the prior art, there is no need to drill one by one. This drilling method can drill multiple glass tubes at one time, improving the drilling efficiency. The drilling diameter and heating time of multiple glass tubes can be controlled, and the drilling position is controllable, thus improving the drilling quality of the glass tubes.

[0023] The drilling lamp head 31 in this embodiment selects a prior art product, which is connected to the gas pipeline. By burning the gas, the glass tube can be heated and drilled. The diameter of the outer circle formed by the burning of the flame can be adjusted through the drilling lamp head 31. This adjustment method is a prior art and can be reasonably adjusted according to the actual situation (including the drilling diameter). In the present invention, micro-drilling is performed on the glass tube. Micro-drilling means that the drilling diameter is small or tiny, so it is defined as micro-drilling.

[0024] In some embodiments, referring to Figure 2 , the glass tube micro-drilling device further includes a plurality of preheating torches 4, which are arranged in front of the synchronous following assembly 1 in the glass tube transportation direction. The plurality of preheating torches 4 are arranged at equal intervals in sequence along the glass tube transportation direction. The plurality of preheating torches 4 are adapted to preheat the drilling positions of a plurality of glass tubes simultaneously. The preheating powers of the plurality of preheating torches 4 are the same and can be adjusted and set. On the production line, the support and transportation of a plurality of glass tubes are realized through the arranged chain or V-shaped pallet, and the transportation direction is towards one direction, that is, Figures 1-2 the direction from right to left in

[0025] . And the plurality of preheating torches 4 are connected to the side of the production line. During the operation of the production line and the transportation of a plurality of glass tubes, the plurality of preheating torches 4 can preheat a plurality of glass tubes passing by them in sequence, that is, preheat and raise the temperature of the drilling positions of the glass tubes to be drilled, which is convenient for the subsequent drilling operation, can complete the drilling with one drilling, and can also improve the drilling efficiency. In this embodiment, parameters such as the flame temperature or heating temperature generated by the plurality of preheating torches 4 can be adjusted and controlled. For example, the same heating temperature can be set, or a gradient heating temperature can be set, that is, from the direction away from the synchronous following assembly 1 to the direction close to the synchronous following assembly 1, the heating temperature of the plurality of preheating torches 4 gradually increases. In this way, the gradual heating of the same glass tube can be realized, and the risk of explosion caused by suddenly heating the glass tube at a high temperature can be avoided. In this embodiment, three or more preheating torches 4 can be set, and can be reasonably set according to actual conditions or parameters such as the diameter of the glass tube. Of course, the set positions can also be adjusted. In this embodiment, a support plate 5 is provided on the side wall of the production line, and the plurality of preheating torches 4 are arranged on the upper end of the support plate 5. The preheating torch 4 is a product of the prior art, which is connected to the gas pipeline. After the gas is passed, the gas can be ignited to generate a flame to heat the glass tube. Parameters such as the height of its flame and heating temperature can be reasonably adjusted according to actual conditions. Figure 4 , the glass tube micro-drilling device further includes a purging assembly 6, which is connected to the mobile end of the synchronous following assembly 1 and is arranged close to the drilling assembly 3. When the lifting block 21 lifts the glass tube, the purging assembly 6 is used to purge towards the inside of the glass tube. Since the glass tube is arranged horizontally, the purging assembly 6 blows horizontally from one end of the glass tube towards the inside of the glass tube to blow the dust, impurities, etc. located inside the glass tube, blow the dust, impurities, etc. away from the glass tube, or can blow them away from the other end of the glass tube (when the other end is open). Among them, parameters such as the purging speed and power of the purging assembly 6 can be set, so that the blowing wind force can be adjusted to realize the cleaning of dust, impurities, etc. at different positions and of different volumes inside the glass tube.

[0026] In some embodiments, refer to Figures 1 to 4 , the synchronous following component 1 includes a slide rail 11, a sliding plate 12, and a driver 13. The slide rail 11 is connected to the side of the glass tube production line. A plurality of sliders 14 are slidably connected to the slide rail 11, and the sliding direction of the plurality of sliders 14 is along the glass tube transportation direction. The sliding plate 12 is connected to the plurality of sliders 14, and an operation panel 15 is connected to the top of the sliding plate 12. The operation panel 15 is connected to the punching component 3 and is used to control the operation of the punching component 3. The mobile end is the sliding plate 12. One end of the driver 13 is connected to the slide rail 11, and the other end is connected to the slider 14. The driver 13 is used to intermittently drive the slider 14 to slide, so that the sliding plate 12 intermittently follows the movement of the glass tube production line. One side surface of the slide rail 11 is connected to the side of the production line, the slide rail 11 is horizontally arranged, there are two sliders 14 and they slide on the slide rail 11 at the same time. The sliders 14 are connected to the sliding plate 12, which plays a role in sliding support for the sliding plate 12, and the sliding plate 12 is also horizontally arranged. The slider 14 is C-shaped, and its lower end side is slidably connected to the slide rail 11, and its upper end is connected to the bottom end of the sliding plate 12. The driver 13 is a kind of air cylinder or electric cylinder. One end is fixedly connected to the upper end of the slide rail 11, and the other end can stretch and push, and thus can push the slider 14 to slide, thereby adjusting the positions of the lifting component 2 and the punching component 3. By controlling the driver 13 to stretch intermittently, the lifting component 2 can successively lift a plurality of glass tubes.

[0027] In some embodiments, refer to Figures 1 to 3 , the lifting block 21 of the lifting component 2 is fixedly connected to the side of the sliding plate 12 close to the glass tube production line. The lifting component 2 further includes a bracket 22 and a serrated support plate 23. The bracket 22 is connected to the upper end of the lifting block 21. The serrated support plate 23 is detachably connected to the upper end of the bracket 22. A plurality of grooves formed at the upper end of the serrated support plate 23 are all used to accommodate glass tubes, and the layout spacing of the plurality of grooves is the same as the layout spacing of the plurality of glass tubes. The serrated support plate 23 is used to push up or down adjacent multiple glass tubes on the glass tube production line by means of the lifting of the lifting block 21. The lifting block 21 is a kind of telescopic air cylinder or electric cylinder. By controlling its telescopic movement, the lifting height of the glass tube can be adjusted, and thus the glass tube can be lifted to different heights to meet the punching requirements. The cross-section of the bracket 22 is L-shaped, and is provided with a plurality of screw holes, and can be detachably connected to the serrated support plate 23. The serrated support plate 23 can simultaneously push up one end of a plurality of glass tubes, and thus the punching operation can be performed on the glass tubes.

[0028] It should be noted that since the lifting of the upper end of the jacking block 21 is along the vertical direction and the glass tube is generally arranged horizontally, after one end of the glass tube is jacked up by a certain height, the angle formed between the punching direction of the punching assembly 3 and the axial direction of the glass tube is an acute angle (<90°). At this time, it will not affect the punching requirements for the glass tube, that is, this method is within the scope of punching requirements or specifications.

[0029] In some embodiments, please refer to Figures 1 to 4 , the punching assembly 3 includes a plurality of lifters 32, which are respectively connected to the upper end of the sliding plate 12 at equal intervals, and the layout intervals are the same as the layout intervals of the plurality of glass tubes. The plurality of lifters 32 all pass through the operation panel 15; a plurality of punching lamp heads 31 are respectively connected to the upper ends of the plurality of lifters 32 one by one. The lifter 32 is used to drive the punching lamp head 31 to lift, and a flame is ejected from the upper end of the punching lamp head 31 to heat and punch the side wall of the glass tube; wherein, the operation panel 15 is provided with a plurality of control modules 16, and the plurality of control modules 16 are respectively connected to the plurality of punching lamp heads 31 one by one, and are used to respectively control the punching diameter and heating time of the plurality of punching lamp heads 31. The operation panel 15 is in a zigzag shape, that is, it includes two plate bodies. One plate body is arranged horizontally and is located above the sliding plate 12, and the upper end of the other plate body is connected to the side of the previous plate body. It is arranged obliquely and slopes downward, which plays a role in protecting the sliding plate 12, the slider 14, etc., but does not affect the sliding of the slider 14. The lifter 32 is arranged on the upper end of the sliding plate 12, and it is a telescopic cylinder or electric cylinder, which can telescopically move along the vertical direction, so as to push the punching lamp head 31 to move and adjust the height of the punching lamp head 31. The control module 16 is a kind of knob. Screwing clockwise reduces the flame of the punching lamp head 31, and screwing counterclockwise increases it. When it is reduced, the punching diameter becomes smaller, and when it is increased, the punching diameter becomes larger, thereby adjusting the punching diameter. Each control module 16 corresponds to the regulation of one punching lamp head 31.

[0030] In the present invention, the punching lamp head 31 can be lifted and adjusted (regulated by the lifter 32), that is, when punching is required, the punching lamp head 31 is lifted, and punching operations are performed after rising. After punching is completed, it descends. After descending, the jacking assembly 2 descends and retracts, and the punched glass tube remains in its original position on the production line. At this time, a cycle of punching operations is completed.

[0031] In some embodiments, please refer to Figures 2 to 3, a telescopic rod 33 is detachably connected to the side wall of the sliding plate 12 and on the side of the operation panel 15. The upper end of the telescopic rod 33 is connected to a lifter 32, and the upper end of the lifter 32 is connected to an extended lamp head 34. The extended lamp head 34 is arranged along the layout direction of a plurality of punching lamp heads 31 and is arranged in a row with the plurality of punching lamp heads 31. The extended lamp head 34 is adapted to heat and punch the glass tube simultaneously with the plurality of punching lamp heads 31, and the distance between the extended lamp head 34 and its adjacent punching lamp head 31 can be adjusted. In the above embodiment, the number of punching lamp heads 31 is six, which is an even number. To adjust the number of punching lamp heads 31 to an odd number, an additional telescopic rod 33 is added at the right end ( Figure 3 and Figure 5 in) of the sliding plate 12. The telescopic rod 33 is in a Z shape, with the lower end connected to the upper end of the sliding plate 12 and the upper end connected to a lifter 32. By lifting and lowering the lifter 32, the height of the extended lamp head 34 can be adjusted, so as to lift and punch simultaneously with the plurality of punching lamp heads 31, thus realizing the lifting and punching operations on an odd number of glass tubes.

[0032] As a preference, please refer to Figure 5 , a sliding plate 35 is slidably connected to the upper end of the sliding plate 12, and the lower end of the telescopic rod 33 is slidably connected to the upper end of the sliding plate 35. Then, by pushing the telescopic rod 33, it can slide on the sliding plate 35, thereby adjusting the distance between the telescopic rod 33 and the sliding plate 12, that is, adjusting the distance between the extended lamp head 34 and its adjacent punching lamp head 31. After the telescopic rod 33 is slidably adjusted, it can also be locked and fixed on the sliding plate 35.

[0033] As a preference, please refer to Figure 5 , a short rod 36 is detachably connected to the side wall of the upper end of the telescopic rod 33, and the lifter 32 is connected to the upper end of the short rod 36. The function of this setting method is to facilitate the installation and disassembly of the lifter 32 and the extended lamp head 34. When the extended lamp head 34 is not needed, the short rod 36 can be detached from the telescopic rod 33; when it is needed, it can be installed on the telescopic rod 33. That is, the telescopic rod 33 does not need to be frequently disassembled, achieving the effect of saving time and effort.

[0034] To keep the aperture after punching uniform and make the hole as circular as possible to improve the punching quality, in some embodiments, please refer to Figures 3 to 4, a plurality of first rotating platforms 37 arranged in a row are connected to the upper end of the sliding plate 12, and the arrangement spacing is the same as the arrangement spacing of the plurality of glass tubes. The upper end of the first rotating platform 37 has a circumferential rotation degree of freedom in the horizontal plane. A plurality of elevators 32 are respectively connected to the upper ends of the plurality of first rotating platforms 37 one by one. The punching lamp head 31 can rotate circumferentially during heating and punching to adjust the punching diameter. The first rotating platform 37 is an electric rotating platform in the prior art. After being controlled, its upper end can achieve circumferential rotation, so as to adjust the circularity of the punching diameter of the punching lamp head 31, that is, the punched hole can be kept circular to the greatest extent, preventing the existence of holes such as oval holes. During the punching process, the first rotating platform can be controlled to rotate, which does not affect the punching operation either. When the punching lamp head 31 rotates circumferentially during the punching process, the punched hole can be kept circular or approximately circular to the greatest extent, which is beneficial to improving the punching quality. The rotation of the punching lamp head 31 and the first rotating platform 37 can cooperate with each other to complete punching.

[0035] In some embodiments, please refer to Figure 4 , the purging assembly 6 includes a plurality of purging pipes 61 and a purging pump 62. The plurality of purging pipes 61 are all connected to the upper end of the operation panel 15. The plurality of purging pipes 61 are arranged in a row and the uniform distribution spacing is the same as the arrangement interval of the plurality of glass tubes. The air outlet ends of the purging pipes 61 are arranged horizontally and are used for blowing air into the interior of the glass tubes; the purging end of the purging pump 62 is respectively communicated with the plurality of purging pipes 61 through pipelines 63. The purging pump 62 is used for blowing air into the plurality of purging pipes 61 to purge and clean the impurities inside the glass tubes. One end of the purging pipe 61 is communicated with the air outlet end of the pipeline 63, and the other end of the purging pipe 61 is the air outlet end and faces the interior of one end of the lifted glass tube. The gas discharged through the purging pipe 61 can be blown into the interior of the glass tube, so that the impurities inside the glass tube can be purged or discharged. The purging pump 62 is a prior art or a nozzle. By controlling its operation, the control of gas purging can be realized, and parameters such as the purging wind force can also be controlled by the controller, so as to meet the removal of impurities inside the glass tube.

[0036] To be able to adjust the purging direction of the purging pipe 61, in some embodiments, please refer to Figure 4 , a plurality of second rotating platforms 64 arranged in a row are connected to the upper end of the operation panel 15, and the arrangement spacing is the same as the arrangement spacing of the plurality of glass tubes. The upper end of the second rotating platform 64 has a circumferential rotation degree of freedom in the horizontal plane.
