Description

A burning sealing device for filament lamp bulb TECHNICAL FIELD

[0001] The present application belongs to the technical field of bulb burning sealing, and specifically relates to a burning sealing device for filament lamp bulb. BACKGROUND

[0002] A bulb (also called an electric bulb or a tungsten lamp) is a man-made light source, which is a device for converting electric energy into light energy, and is used for indication or illumination. A lamp in which a filament, usually made of tungsten, is heated to a white-hot state by an electric current to emit light is called an incandescent lamp. An incandescent lamp filled with halogen and inert gas is called a halogen lamp.

[0003] In the current production process of a bulb, one step is to cut off the glass tube extending from the bulb by a fire burning rotating device, and then the bulb is transferred to a LOGO printing device by a mechanical arm and a piston structure installed at the bottom end of the mechanical arm. When the glass tube is indirectly driven to move upward by the mechanical arm, the excess tube body can be separated from the bulb. The separated bulb is directly placed in the logo pressing device, and thus the bottom end of the glass tube may be stretched to produce a wire, and the bottom end may also be deformed, which affects the production quality of the product under natural cooling.

Embodiment of the application

[0031] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the application.

[0032] As shown in Figures 1 to 8, the application provides a burning and sealing device for filament lamp bulb, which comprises a burning device 1, a LOGO printing device 2 arranged on the side of the burning device 1, a sealing part 3 fixedly connected between the burning device 1 and the sealing part 3, a mechanical arm 11 fixedly connected to the top outer wall of the sealing part 3, and a glass bulb tube 12 intermittently attached and adsorbed to the other end of the mechanical arm 11. The sealing part 3 comprises an L-shaped arc support plate 31, two ear plates 32 arranged on the side wall of one end of the sealing part 3, a motor 33 of a forward and reverse rotation type fixedly connected to the end outer wall of one ear plate 32, a two-way threaded rod 34 fixedly connected to the rotating shaft of the motor 33, two rod bodies of the two-way threaded rod 34 penetratingly and rotatably connected to the plate bodies of the two ear plates 32, clamping plates 35 threadedly connected to the rod bodies on both sides of the two-way threaded rod 34, the two clamping plates 35 being symmetrically arranged, T-shaped pressing pieces 37 arranged on the symmetrically arranged ends of the two clamping plates 35, and a moving and grinding structure arranged on one group of clamping plates 35.

[0033] The inner wall of the rectangular groove 36 is in close sliding connection with the outer wall of the T-shaped abutting piece 37, the smooth outer wall of one end of the T-shaped abutting piece 37 is fixedly connected with two springs 38, the other end of the two springs 38 is fixedly connected with the inner wall of one end of the rectangular groove 36, the outer wall of two ends of the T-shaped abutting piece 37 is fixedly connected with rubber clamping blocks 39, and the inner wall of two ends of the clamping plate 35 is provided with an L-shaped sliding clamping groove 340 capable of being in close sliding connection with the two rubber clamping blocks 39.

[0034] The above scheme is adopted: the motor 33 drives the bidirectional threaded rod 34 to rotate, thereby driving the two clamping plates 35 to move in opposite directions on the bidirectional threaded rod 34, and the moving process can only be translated by being blocked by the L-shaped arc support plate 31, and then the two clamping plates 35 that are translated synchronously drive the T-shaped abutting piece 37 to be translated until the tube body of the glass bulb tube 12 is contacted, and the uniform position is re-cut, avoiding the condition that the tube bodies of the glass bulb tubes 12 are of different lengths and the bottom forms are different, and when the two T-shaped abutting pieces 37 are pressed and extruded during the continuous passive translation of the clamping plate 35, the rubber clamping blocks 39 installed on both ends are limited to slide in the L-shaped sliding clamping groove 340, and the sliding process also synchronously extrudes the two springs 38, until the rubber clamping blocks 39 and one end of the L-shaped sliding clamping groove 340 are clamped and limited.

[0035] The moving polishing structure includes two rectangular grooves 341 provided on one end of the L-shaped arc support plate 31, a screw rod 342 movably sleeved in the inner wall of each of the two rectangular grooves 341, a spring 343 fixedly connected with the bottom end inner wall of each of the two rectangular grooves 341, and the top end of each of the two springs 343 fixedly connected with the bottom end outer wall of each of the two ear plates 32. The two clamping plates 35 are in close sliding connection with one end of the L-shaped arc support plate 31, the top end side wall of the L-shaped arc support plate 31 is fixedly connected with an abutting plate 344, the bottom end side wall of the abutting plate 344 is fixedly connected with an extension rod 345, the bottom of the extension rod 345 is movably sleeved with the middle rod body of the bidirectional threaded rod 34, and the bottom end outer wall of the abutting plate 344 is provided with a group of arc sliding grooves 346, each of the inner walls of the two groups of arc sliding grooves 346 is in close sliding connection with a ball 348, and each of the two groups of balls 348 is movably sleeved with a fence 347, and the bottom end side wall of each of the two fences 347 is fixedly connected with the top end outer wall of each of the two clamping plates 35.

[0036] Adopt the above scheme: when the clamping plate 35 is passively and continuously translated to make the two T-shaped pressing plates 37 press each other, the clamping plate 347 also synchronously contacts the arc sliding groove 346 formed on the outer wall of the pressing plate 344. Under the action of an external force, the ball 348 installed at one end of the clamping plate 347 can smoothly slide along the inner wall of the arc sliding groove 346, thereby generating a motion trajectory of gradually moving downward vertically while moving horizontally, so as to synchronously move downward with the two clamping plates 35. This process will synchronously move downward with the two ear plates 32, the motor 33 and the two-way threaded rod 34, thereby stretching the telescopic rod 345 on the pressing plate 344 to make it generate rod extension. During the process of passively moving downward of the two ear plates 32, the corresponding screw rod one 342 is rotated in place in the rectangular slot 341, and the spring two 343 is pressed during the downward movement process. After the spring two 343, the clamping plate 35 and other structures are conveniently reset. The thread engagement force between the screw rod one 342 and the ear plate 32 is sufficient to support the related structures without additional external force.

[0037] The bottom end outer wall of the two clamping plates 35 is jointly fixedly connected with a threaded hole telescopic plate 349. The threaded hole telescopic plate 349 is provided below the pressing plate 350. The center of the pressing plate 350 is movably sleeved with a ball shaft rod frame 351. The top end outer walls of the pressing plate 350 are movably sleeved with a screw rod two 352 with a ball shaft bottom and a horn grinding column 353, respectively. The top end of the screw rod two 352 is fixedly connected with a rubber block. The rod bodies of the horn grinding column 353 and the screw rod two 352 are movably sleeved with a limiting sleeve rod 354. The rod bodies of the two limiting sleeve rods 354 are inconsistent in shape. The rod bodies of the two limiting sleeve rods 354 are fixedly connected with one end of the L-shaped arc support plate 31. The screw rod two 352 and the threaded hole telescopic plate 349 can be intermittently threadedly connected. The rubber block can be intermittently and slidingly connected with the threaded hole in the threaded hole telescopic plate 349.

[0038] Adopt the above scheme: when the two clamping plates 35 are oppositely translated, the threaded hole telescopic plate 349 is also synchronously driven to contract the plate body, thereby synchronously driving the connected threaded hole telescopic plate 349 to move downward together until the rubber block on the top end of the screw rod two 352 is contacted. Under the blocking of the rubber block, the threaded hole telescopic plate 349 driven to move downward first, thereby being guided to smoothly move downward under the limitation of one limiting sleeve rod 354. Under the action of an external force, the pressing plate 350 can be inclined with the ball shaft rod frame 351 as the axis point.

[0039] The rod body of the horn grinding column 353 and the screw rod two 352 is also fixedly connected with a group of limiting discs 355, and the rod body of the horn grinding column 353 and the screw rod two 352 is jointly fixedly connected with a hemp rope 356, a torsional spring 357 is fixedly connected to the outer wall of a limiting disc 355 close to the bottom of the horn grinding column 353, the bottom end of the torsional spring 357 is fixedly connected to the top end side wall of the pressing and warping plate 350, the top end inner wall of the horn grinding column 353 can be intermittently and tightly connected with the bottom end outer wall of the glass bulb tube 12, and the two T-shaped resistance pieces 37 can also be intermittently and tightly connected with the bottom end outer wall of the glass bulb tube 12.

[0040] By adopting the above scheme: the pressing and warping plate 350 is inclined to drive the horn grinding column 353 on the other side of the top end to move up smoothly under the limiting of the other limiting sleeve rod 354, the horn grinding column 353 moving up will extrude the two T-shaped resistance pieces 37, so that the resistance piece end of the two T-shaped resistance pieces 37 is tightly connected with the column body outer wall of the horn grinding column 353, thereby the bottom end outer wall of the glass bulb tube 12 can be contacted, at this time, the inclination of the pressing and warping plate 350 also presents the maximum angle and cannot be inclined any more, so the rubber block is insufficient to limit the downward movement of the screw hole expansion plate 349, so that the screw rod two 352 is rotated to wind the hemp rope 356, the hemp rope 356 being pulled will generate a friction force with the horn grinding column 353, so as to drive the horn grinding column 353 to rotate, and the top end inner wall of the rotating horn grinding column 353 can rotate and rub the bottom end outer wall of the glass bulb tube 12, so that the bottom end is in a smooth state after being rotated and polished when the temperature is not yet determined.

[0041] It should be noted that: after the two T-shaped resistance pieces 37 cut the glass bulb tube 12, the baffle 347 will also move down under the pressing of the pressing plate 344, thereby driving the two T-shaped resistance pieces 37 and the glass bulb tube 12 to separate, and the cut glass tube body needs to be manually picked up by using an auxiliary tool to avoid affecting the subsequent work flow, so that the horn grinding column 353 is passively moved up to press through the two T-shaped resistance pieces 37, at this time, the two T-shaped resistance pieces 37 have not been clamped into the L-shaped sliding clamping groove 340 through the rubber clamping block 39.

[0042] The working principle and usage process of this invention are as follows: The robotic arm 11, controlled by the system, adsorbs the glass bulb 12, which has already been heated, and then moves it upwards, thereby shortening the bottom of the glass tube by heating. This is the existing operational process, and its motion principle and specific operation will not be elaborated further here. Afterwards, it is rotated and transferred to the LOGO printing equipment 2, passing through the sealing section 3 and stopping. At this time, the motor 33 starts, driving the bidirectional threaded rod 34 to rotate. This causes the two clamping plates 35 to move in opposite directions on the bidirectional threaded rod 34, and the movement process passes through an L-shaped arc. The support plate 31 can only move horizontally due to the obstruction. The two clamping plates 35 that move horizontally to each other will simultaneously drive the T-shaped abutment 37 to move horizontally until they contact the tube body of the glass bulb tube 12 and cut it again at a uniform position to avoid the situation that the tube bodies of the glass bulb tubes 12 are different in length and bottom shape. After the cutting operation, the two T-shaped abutment 37 will continue to move passively in the clamping plate 35. When they press against each other and generate squeezing force, they will slide in the L-shaped sliding groove 340 through the rubber blocks 39 installed at both ends. During the sliding process, they will also squeeze the two springs 38 simultaneously until the rubber blocks 39 and one end of the L-shaped sliding groove 340 are locked and limited.

[0043] In the process of the passive continuous translation of the clamping plates 35, the two T-shaped pressing plates 37 are pressed against each other, the barrier plate 347 also synchronously contacts the arc sliding groove 346 opened on the outer wall of the pressing plate 344. Under the action of an external force, the ball 348 installed at one end of the barrier plate 347 can smoothly slide along the inner wall path of the arc sliding groove 346, thereby generating a motion trajectory of gradually moving vertically downward while horizontally translating, which can drive the two clamping plates 35 to synchronously move downward. This process will drive the two ear plates 32, the motor 33, and the two-way threaded rod 34 to synchronously move downward, thereby stretching the telescopic rod 345 on the pressing plate 344 to make it extend. In the process of the passive downward movement of the two ear plates 32, the corresponding screw rod one 342 rotates in place in the rectangular slot 341, and the downward movement process squeezes the spring two 343, which can subsequently drive the clamping plates 35 and other structures to reset. The thread engagement force between the screw rod one 342 and the ear plate 32 is sufficient to support the related structures without additional external force. When the two clamping plates 35 move in opposite directions, the screw hole telescopic plate 349 will also synchronously move downward, thereby synchronously driving the connected screw hole telescopic plate 349 to move downward until it contacts the rubber block on the top end of the screw rod two 352. Under the blocking of the rubber block, the screw hole telescopic plate 349 driven by the downward movement will be guided to smoothly move downward under the limitation of the limiting sleeve rod 354. Under the action of an external force, the pressure plate 350 can be tilted around the ball shaft frame 351, thereby driving the horn grinding column 353 on the other side of the top end of the pressure plate 350 to smoothly move upward under the limitation of the other limiting sleeve rod 354. The upward moving horn grinding column 353 will squeeze through the two T-shaped pressing plates 37, so that the pressing mouth of the two T-shaped pressing plates 37 is attached to the column body outer wall of the horn grinding column 353, thereby contacting the bottom end outer wall of the glass bulb tube 12. At this time, the inclination of the pressure plate 350 also presents the maximum angle and cannot continue to incline, so the rubber block cannot continue to limit the downward movement of the screw hole telescopic plate 349, and the screw rod two 352 rotates to wind the hemp rope 356. The pulled hemp rope 356 will generate friction with the horn grinding column 353, thereby driving the horn grinding column 353 to rotate, and the top end inner wall of the rotating horn grinding column 353 can rotate and rub the bottom end outer wall of the glass bulb tube 12, so that the bottom end is in a smooth state after rotation and polishing when the temperature is still not fixed, thereby preventing the quality problems such as wire drawing and bottom deformation of the glass tube bottom end that may occur after stretching.
