The lamp tube 81 is the main part of the flash tube, while the connecting tube 82 is an auxiliary part in the production process. The connecting tube 82 needs to be cut off in the subsequent production process.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0028] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0029] refer to Figures 1-10 .

[0030] This invention provides a lamp tube sealing machine, comprising a machine base 10, on which a lamp tube feeding mechanism 20, a glass rod feeding mechanism 30, a shaping mechanism 40, and an electrode feeding mechanism 50 are mounted; the lamp tube feeding mechanism 20 includes a first Y-axis linear drive device 21 mounted on the machine base 10, a first rotary clamping device 22 driving the first Y-axis linear drive device 21, a first X-axis linear drive device 23 mounted on one side of the first rotary clamping device 22, and a flame-spraying device 24 driving the first X-axis linear drive device 23; the glass rod feeding mechanism 30 includes a second X-axis linear drive device 31 mounted on the machine base 10, a first rotary clamping device 22 driving the first X-axis linear drive device 23, and a flame-spraying device 24 driving the first X-axis linear drive device 23; the glass rod feeding mechanism 30 includes a second X-axis linear drive device 31 mounted on the machine base 10, a first X-axis linear drive device 23 driving the first X-axis linear drive device 24, and a flame-spraying device 24 driving the first X-axis linear drive device 23. The glass rod conveying mechanism 32 on the actuator 31 conveys the glass rod in the X-axis direction; the shaping mechanism 40 includes a first support 41 mounted on the machine base 10, a Z-axis linear drive device 42 mounted on the first support 41, a second support 43 mounted on the Z-axis linear drive device 42, and a roller 44 rotatably connected to the second support 43; the electrode feeding mechanism 50 includes a loading mechanism and a feeding mechanism. The feeding mechanism includes a third X-axis linear drive device 51 mounted on the machine base 10 and a second rotary clamping device 52 mounted on the third X-axis linear drive device 51. The loading mechanism supplies electrode material to the second rotary clamping device 52.

[0031] In practical use, initially, the first rotary clamping device 22 is located at one end of the first Y-axis linear drive device 21. The worker places one end of the lamp tube 81 of the lamp body 80 onto the first rotary clamping device 22 for clamping, and places the electrode material onto the feeding mechanism. The feeding mechanism supplies the electrode material to the second rotary clamping device 52, and the sealing glass rod is placed onto the glass rod conveying mechanism 32. First, the first Y-axis linear drive device 21 drives the first rotary clamping device 22 to move to the side of the glass rod feeding mechanism 30. At this time, the end of the lamp tube 81 will be concentric with the glass rod. The first rotary clamping device 22 drives the lamp tube 81 to rotate, and the first X-axis linear drive device 23 drives the flame-spraying device 24 to move back and forth towards the end of the lamp tube 81 to perform silicon burning treatment and preheating before glass solder coating. Then, the second X-axis linear drive device 31 drives the glass rod to be conveyed to the end of the lamp tube 81. The glass rod conveying mechanism 32 continuously conveys the glass rod forward, thereby sealing the lamp tube 81. Glass solder is applied to the end of tube 81. After the solder is applied, the end of tube 81 is sealed. Air is blown into tube 81 to break the seal at the end of tube 81 to facilitate electrode insertion. After the glass solder is applied, the first Y-axis linear drive device 21 drives the first rotary clamping device 22 to move to the shaping mechanism 40. The Z-axis linear drive device 42 drives the bottom of the roller 44 to press against the end of tube 81. The tube 81, which is rotated by the first rotary clamping device 22, drives the roller 44 to rotate, thereby shaping the broken opening at the end of tube 81. After the broken opening is shaped, the first rotary... The first rotary clamping device 22 stops rotating and is driven by the first Y-axis linear drive device 21 to move to the electrode feeding mechanism 50 side. At this time, the end of the lamp tube 81 is concentric with the electrode clamped on the second rotary clamping device 52. The end of the lamp tube 81 is heated again by the flame device 24. At the same time, the first rotary clamping device 22 and the second rotary clamping device 52 drive the lamp tube 81 and the electrode to rotate respectively. The second rotary clamping device 52 is driven by the third X-axis linear drive device 51 to insert the electrode into the end of the lamp tube 81, so as to tightly insert the electrode into the end of the lamp tube. In the glass solder, air bubbles or gaps are avoided between the electrode and the glass solder. Then, the bottom of the roller 44 is driven by the Z-axis linear drive device 42 to press against the end of the lamp tube 81. The rotating lamp tube 81 drives the roller 44 to rotate, thereby shaping the end of the lamp tube 81. The electrode insertion and sealing process is completed at the end of the lamp tube 81, and the sealing process of one end of the lamp tube 81 is completed. By repeating the above steps, the sealing process of the other end of the lamp tube 81 can be completed. This realizes the automation of lamp tube sealing, ensures stable product processing quality, effectively improves the production efficiency of lamp tubes, reduces labor input, and reduces production costs.

[0032] Based on the above embodiments, both the first rotary clamping device 22 and the second rotary clamping device 52 include a support base 220, an outer sleeve 221 that passes through the support base 220, an inner sleeve 222 that is rotatably disposed in the outer sleeve 221, a push rod 223 that is movably disposed in the inner sleeve 222, a conical sleeve 224 that is fixedly connected to one end of the inner sleeve 222 and is conical in shape, a first drive cylinder 225 that is fixedly connected to one side of the support base 220 and is drivenly connected to one end of the push rod 223, and a first drive motor 226 that is fixedly connected to one side of the support base 220 and is drivenly connected to the inner sleeve 222. The outer wall of the conical surface of the conical sleeve 224 is evenly distributed with a plurality of first guide grooves 227. A sliding plate 25 that matches the first guide groove 227 is movably disposed on the first guide groove 227. A push plate 250 is disposed on the inner side of the sliding plate 25. A second guide plate that matches the push plate 250 is passed through the bottom of the first guide groove 227. The push plate 250 is movably mounted on the second guide groove 228 and extends into the conical sleeve 224. One end of the push rod 223 is provided with a ring 26. The side wall of the push plate 250 is provided with a groove 251 that matches the ring 26. The ring 26 is movably mounted on the groove 251. One end of the slide plate 25 extends towards the center line of the conical sleeve 224 and is provided with a clamping end 252. A baffle covering the first guide groove is fixedly connected to the outer wall of the conical sleeve. The wall is provided with a third guide groove, and the top of the slide plate is provided with a guide step that matches the third guide groove. The guide step is movably set on the third guide groove. The first rotary clamping device 22 also includes an air inlet pipe 27 connected to one end of the push rod 223. The other end of the push rod 223 is fixedly connected to a feeding sleeve 28. The feeding sleeve 28 is fixedly connected to one end of the push rod 223. An air passage 229 is provided through the push rod 223 to connect the output end of the air inlet pipe 27 and the feeding sleeve 28. Specifically, when the first rotary clamping device 22 and the second rotary clamping device 52 perform clamping or releasing operations on the lamp tube 81 and the electrode respectively, the first drive cylinder 225 drives the push rod 223 to move forward or backward along the inner sleeve 222. The ring 26 applies a forward or backward pushing force to the slot 251, which drives the slide plate 25 and the push plate 250 to move along the first guide groove 227 and the second guide groove 228 respectively, realizing the contraction or expansion action between the clamping ends 252, thereby allowing the clamping ends 25... 2. Clamp or release the lamp tube or electrode; after clamping the lamp tube or electrode, drive the inner sleeve 222 to rotate through the first drive motor 226, which in turn drives the conical sleeve 224 to rotate, thereby causing the lamp tube or electrode to rotate; connect the air inlet pipe 27 of the first rotary clamping device 22 to the output end of the air supply device. When the air supply device supplies air to the air inlet pipe 27, the gas will be transported through the air passage 229 and the inside of the feeding sleeve 28 to the end of the lamp tube 81, thereby blowing the glass solder seal at the end of the lamp tube 81 to burst.

[0033] Based on the above embodiments, the glass rod feeding mechanism 30 further includes a second Y-axis linear drive device 33 driven on the second X-axis linear drive device 31, and a height adjustment device 34 driven on the second Y-axis linear drive device 33. The glass rod transmission mechanism 32 includes a base plate 320 mounted on the height adjustment device 34, a first support member 321 and a second support member 322 respectively disposed at both ends of the base plate 320, and a transmission mechanism disposed at one end of the base plate 320. The first support member 321 and the second support member 322 are both provided with guide holes 323. The transmission mechanism includes a second drive motor 324 disposed on one side of the base plate 320, an upper roller 325 driven and connected to the second drive motor 324, and a lower roller 326 rotatably connected to the top of the base plate 320 and located below the upper roller 325. The upper roller 325 and the lower roller 326 are both provided with annular grooves 327 on their wheel surfaces. Specifically, the position of the glass rod conveying mechanism 32 can be adjusted in the Y-axis and Z-axis directions by the second Y-axis linear drive device 33 and the height adjustment device 34, respectively, to adapt to the coating operation of glass rods of different sizes. The glass rod is conveyed forward under the guidance of the two guide holes 323. The upper roller 325 is driven to rotate by the second drive motor 324, and the glass rod will be conveyed between the annular groove 327 of the upper roller 325 and the lower roller 326.

[0034] Based on the above embodiments, the feeding mechanism includes a support frame 53 mounted on the machine base 10, a third Y-axis linear drive device 54 mounted on the support frame 53, and a feeding plate 55 connected to the third Y-axis linear drive device 54. A feeding groove 550 for placing electrodes is provided on one side of the feeding plate 55. Specifically, the feeding groove 550 is matched with the electrode material. After the worker places the electrode on the feeding groove 550, when the second rotary clamping device 52 is located on the feeding mechanism side, the third Y-axis linear drive device 54 drives the feeding plate 55 to move towards the second rotary clamping device 52. The second rotary clamping device 52 then clamps the electrode on the feeding groove 550, completing the electrode feeding process.

[0035] Based on the above embodiments, a glass rod braking mechanism and a lamp tube positioning mechanism are provided on the base plate 320. The glass rod braking mechanism includes a pneumatic finger 60 disposed on the base plate 320 and a clamping arm 61 driven to be connected to two grippers of the pneumatic finger 60. One end of the clamping arm 61 is provided with a V-shaped groove 62. By driving the two V-shaped grooves 62, the glass rod is clamped to achieve the transmission and stopping operation of the glass rod. The lamp tube positioning mechanism includes a support frame 70 fixedly connected to the base plate 320 and a longitudinal support frame fixedly connected to the top of the support frame 70. The system includes a support plate 71, a longitudinal slide plate 72 slidably connected to the longitudinal support plate 71 along the Z-axis, a second drive cylinder 73 disposed on the longitudinal support plate 71 and drivenly connected to the longitudinal slide plate 72, a transverse slide plate 74 slidably connected to the longitudinal slide plate 72 along the X-axis, a third drive cylinder 75 disposed on the longitudinal slide plate 72 and drivenly connected to the transverse slide plate 74, and a connecting arm 76 fixedly connected to the transverse slide plate 74. One end of the connecting arm 76 is orthogonally provided with a Y-axis positioning plate 77 and an X-axis positioning column 78. Specifically, after the lamp tube 81 is conveyed to a position concentric with the glass rod, the second drive cylinder 73 drives the longitudinal slide plate 72 to descend along the longitudinal support plate 71, so that the Y-axis positioning plate 77 moves to be opposite one end of the lamp tube 81. Then, the third drive cylinder 75 drives the transverse slide plate 74 to move along the longitudinal slide plate 72 toward the connecting pipe 82 until the end of the X-axis positioning column 78 abuts against the outer wall of the connecting pipe 82. At this time, the Y-axis positioning plate 77 also abuts against one end of the lamp tube 81, so that the Y-axis positioning plate 77 and the X-axis positioning column 78 respectively position the lamp tube 81 and the connecting pipe 82, preventing the lamp tube body 80 from being inaccurately positioned. During the glass rod transmission process, the pneumatic finger 60 drives the clamping arm 61 to retract. The two retracted clamping arms 61 will drive the V-shaped slots 62 on both sides to hold the glass rod tightly, thereby stopping the transmission of the glass rod and preventing the glass rod from continuing to be conveyed forward, thus improving the product processing accuracy.

[0036] Based on the above embodiments, the height adjustment device 34 includes a "T-shaped" base 340, an "inverted T-shaped" support 341 slidably connected to the "T-shaped" base 340 along the Z-axis direction, and an L-shaped rotating member 342 rotatably disposed on one side of the "T-shaped" base 340. An adjusting screw 343 is threadedly connected to one side of the "T-shaped" base 340, and one end of the adjusting screw 343 abuts against one end of the L-shaped rotating member 342. A support rod 344 is provided on one side of the "inverted T-shaped" support 341, and the bottom end of the support rod 344 abuts against the other end of the L-shaped rotating member 342. Specifically, a support plate is provided on the "T-shaped" base 340, and a screw hole matching the adjusting screw 343 is provided through the support plate. The adjusting screw 343 is threaded into the screw hole. When it is necessary to adjust the height of the glass rod transmission mechanism 32, the length of the end of the adjusting screw 343 extending out of the screw hole is adjusted by rotating the adjusting screw 343, so as to drive the L-shaped rotating part 342 to rotate. The other end of the L-shaped rotating part 342 will apply an upward pushing force to the support rod 344, thereby driving the "inverted T-shaped" support seat 341 to be raised and lowered.

[0037] Based on the above embodiment, an annular member 29 is sleeved on one side of the inner sleeve 222, and a slot 290 is provided through one side of the annular member 29. A slotted photoelectric switch 291 is provided on one side of the support base 220, and the annular member 29 is movably disposed on the photosensitive slot of the slotted photoelectric switch 291.
