Description

Technical Field

[0001] The invention relates to LED lamp production equipment, in particular to an inflatable pressure sealing seat and a vacuum inflatable pressure sealing machine equipped with the inflatable pressure sealing seat. Background Art

[0002] At present, the production of LED lamps includes steps such as vacuuming, filling with inert gas and sealing. Each process step requires corresponding special equipment to vacuum, fill with inert gas and seal the LED lamps respectively, which makes the number of equipment required for the production of LED lamps large, thereby reducing the production efficiency and increasing the production cost. Therefore, it is necessary to design a multifunctional vacuuming, filling and sealing machine with the functions of vacuuming, filling with inert gas and sealing to improve the production efficiency of LED lamps and save production costs. Since both ends of the LED lamp tube need to be sealed, it is necessary to design an inflating and sealing seat to realize the function of inflating or vacuuming from both ends of the LED lamp tube.

[0003] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a new type of inflatable pressure seal seat with greater industrial utilization value. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide an inflating and sealing seat that can inflate or evacuate the two ends of an LED lamp tube to assist in achieving the function of sealing the lamp tube. In addition, the present invention also provides a multifunctional vacuum inflating and sealing machine that integrates the functions of evacuating the hollow, filling with inert gas and sealing.

[0005] The inflatable pressure sealing seat of the present invention comprises a pressure sealing seat body, an air transmission channel is arranged in the pressure sealing seat body, and the two ends of the air transmission channel are respectively connected with the openings on the pressure sealing seat body, and a core rod connected with the pressure sealing seat body is also arranged in the air transmission channel, a core rod main air channel connected with the air transmission channel is arranged in the core rod, and a core rod side air channel connected with the core rod main air channel is also arranged on the side of the core rod, and a pressure sealing ring made of elastic material is arranged on the outside of the core rod, the bottom of the pressure sealing ring is located in the accommodating groove on the surface of the pressure sealing seat body, and a core sleeve is arranged above the pressure sealing ring, the core sleeve is a tubular structure with openings at both ends and hollow inside, and a gap is provided between the inner side surface of the core sleeve and the outer side surface of the core rod, and the bottom end of the core sleeve has an extrusion plate in contact with the pressure sealing ring, and the top end of the pressure sealing seat is also provided with a locking cap connected with the pressure sealing seat, the bottom end of the locking cap is connected to the top of the pressure sealing seat body, and the top wall of the locking cap has an opening connected with the inner cavity of the core sleeve and the main air channel of the core rod.

[0006] Furthermore, in the inflatable pressure sealing seat of the present invention, a support ring connected to the accommodating groove is provided in the accommodating groove, and the pressure sealing ring is located above the support ring.

[0007] Furthermore, in the inflatable pressure sealing seat of the present invention, a handle fixedly connected to the locking cap is provided on the outer side of the locking cap, and the locking cap is threadedly connected to the pressure sealing seat body.

[0008] Furthermore, in the inflation pressure sealing seat of the present invention, the bottom surface of the core rod is provided with a ventilation groove, and the side wall of the ventilation groove is provided with a ventilation port connected with the ventilation groove.

[0009] Furthermore, in the inflation and pressure sealing seat of the present invention, the gas transmission channel includes a vertical channel arranged vertically and a transverse channel connected to the vertical channel.

[0010] Furthermore, in the inflatable pressure sealing seat of the present invention, a bearing is also provided above the extrusion plate.

[0011] Through the above scheme, the present invention has at least the following advantages: the arrangement of the inflatable pressure sealing seat, the pressure sealing seat body, the core rod, the pressure sealing ring and other components of the present invention enables the inflatable pressure sealing seat to inflate or vacuum the LED lamp tube from both ends to assist in realizing the pressure sealing function of the lamp tube. Specifically, during the gas filling, degassing and pressure sealing, one end of the LED lamp tube is inserted into the top end of the core rod, and its top extends out from the opening of the locking cap. Then the locking cap moves downward, and the top wall of the locking cap drives the core sleeve to move downward. As the core sleeve moves downward, the sealing ring in contact with the core sleeve produces a certain deformation under the extrusion of the core sleeve, and then the LED lamp tube located between the core sleeve and the core rod is pressed against the middle of the core sleeve. When the LED lamp tube is pressed, the operator can input nitrogen into the main airway of the core rod through the opening at the top of the core rod connected to the main airway of the core rod, and output it into the LED lamp tube from the core rod side airway connected to the main airway of the core rod. While supplying gas, the operator heats the LED lamp tube through the heating blocks on both sides of the LED lamp tube until the tube wall is melted, and then the pressing molds on both sides of the lamp tube are closed, so as to flatten and seal the lamp tube. The input of nitrogen can prevent the chip in the lamp tube from being damaged due to heat when the lamp tube is heated. When one end of the lamp tube is sealed, the operator first loosens the locking cap and pulls the lamp tube out of the core rod. Then the operator turns it upside down on the core rod and seals it in a similar way to the above. However, before sealing, the lamp tube is first evacuated with a vacuum pump to extract the nitrogen in the lamp tube, and argon is input from the opening on the seal seat. The argon is input from the gas transmission channel in the seal seat and output from the core rod side airway to the lamp tube. Then the sealing operation is performed through the above-mentioned heating and sealing methods.

[0012] In summary, the inflatable pressure-sealing seat of the present invention can inflate or evacuate the LED lamp tube from both ends to assist in achieving the pressure-sealing function of the lamp tube.

[0013] A vacuum inflating and sealing machine including the above-mentioned inflating and sealing seat, including a workbench, a rotating seat assembly arranged on the surface of the workbench, a rotating disk connected to the rotating seat assembly, an inflating device located in the middle of the rotating disk, and a plurality of sealing seat assemblies located at the edge of the rotating disk and circumferentially distributed around the rotating disk, the rotating seat assembly including a fixed seat fixedly arranged on the workbench, a rotating seat located above the fixed seat and rotatable relative to the fixed seat, a plurality of rotating airways are arranged on the rotating seat, and a fixed airway corresponding to the rotating airway is arranged on the fixed seat, the vacuum inflating and sealing machine also includes at least one group of heating components, at least one group of heating components in the heating components includes a molding component, the rotating disk and the rotating seat are connected to each other. The rotating seat is fixedly connected, and the inflation device includes an inflation shell, and the side wall of the inflation shell is provided with an air inlet and a plurality of inflation ports corresponding to the pressure sealing seat assembly. The inflation shell is fixedly arranged in the middle of the rotating disk, and the pressure sealing seat assembly includes the pressure sealing seat, and the core rod main air channel of the pressure sealing seat is connected with the inflation port of the inflation shell through a pipeline, and the air delivery channel of the pressure sealing seat is connected with the rotating air channel on the rotating seat through a pipeline. The heating assembly includes a heating block moving seat, at least one support rod arranged on the heating block moving seat, and a heating block is arranged on the support rod. The molding assembly includes a die moving seat, dies located on both sides of the support rod, and a die driving member arranged on the die moving seat and used to drive the die to move.

[0014] Furthermore, in the vacuum inflating and sealing machine of the present invention, the sealing seat assembly also includes a mounting plate, one end of which is connected to the rotating disk, and the other end of which is connected to the sealing seat.

[0015] Furthermore, in the vacuum filling and sealing machine of the present invention, the die driving member includes a connecting rod hinged on the die moving seat, and one end of the connecting rod is hinged to the die.

[0016] Furthermore, in the vacuum, inflating and sealing machine of the present invention, a connecting shaft is connected to the rotating seat, and oil sealing grooves are provided on the surfaces of the rotating seat and the fixed seat.

[0017] Through the above scheme, the present invention has at least the following advantages: the vacuum filling and sealing machine of the present invention realizes the functions of inflation, vacuuming and sealing of LED lamp tubes through the arrangement of components such as a rotating seat assembly, a sealing seat assembly, a heating assembly and a molding assembly. During the specific work, the operator first inserts one end of the lamp tube into the core rod of the press-sealing seat and locks it with a locking cap. After locking, the external driving motor drives the rotating seat to rotate, and then drives the rotating disk to rotate slowly. As the rotating disk rotates, the press-sealing seat assembly connected to the rotating disk also rotates until the press-sealing seat and the lamp tube on the press-sealing seat rotate to the position corresponding to the heating assembly. Subsequently, the heating block moving seat and the heating block of the heating assembly move toward the press-sealing seat under the drive of the external driving device until the heating block moves to the side of the lamp tube, and then the heating block heats the lamp tube. At the same time or after the heating is completed, the die moving seat and the die move to the predetermined position under the drive of the external driving device. After the heating of the lamp tube is completed, the heating block returns to its original position, and the die moves toward the lamp tube under the drive of the die driving component until the lamp tube is molded by the dies on both sides, and then the die and the die moving seat return to their original positions. During the heating process, the inflation device transports nitrogen to the lamp tube from the top of the press-sealing seat through a pipeline to protect the chip in the lamp tube. After the pressure seal of one end of the lamp tube is completed, the rotating disk drives the pressure seal seat to continue to move until the pressure seal seat rotates through each heating component in turn. The subsequent heating components anneal the lamp tube by gradually reducing the heating temperature. After the rotating disk rotates one circle and drives the lamp tube back to the initial position, the operator pulls the lamp tube out of the core rod, inserts the other open end into the core rod, and locks it with the locking cap. Then, the pressure seal of the other end of the lamp tube is achieved through a similar pressure sealing process as described above. Since the top of the lamp tube has been sealed during this pressure sealing process, the external gas source evacuates the lamp tube and fills it with argon gas from the bottom of the pressure seal seat through the fixed seat, the rotating seat and the pipeline.

[0018] In summary, the vacuuming, filling and sealing machine of the present invention realizes the functions of filling, vacuuming and sealing the lamp tube at the same time, thereby greatly reducing the number of production equipment, improving the processing efficiency of the lamp tube, and reducing the production cost of the lamp tube.

DETAILED DESCRIPTION

[0033] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] The arrangement of the sealing seat body, core rod, sealing ring and other components enables the inflatable sealing seat to inflate or evacuate the LED lamp tube from both ends to assist in achieving the sealing function of the lamp tube. Specifically, during the gas filling, degassing and pressure sealing, one end of the LED lamp tube is inserted into the top end of the core rod, and its top extends out from the opening of the locking cap. Then the locking cap moves downward, and the top wall of the locking cap drives the core sleeve to move downward. As the core sleeve moves downward, the sealing ring in contact with the core sleeve produces a certain deformation under the extrusion of the core sleeve, and then the LED lamp tube located between the core sleeve and the core rod is pressed against the middle of the core sleeve. When the LED lamp tube is pressed, the operator can input nitrogen into the main airway of the core rod through the opening at the top of the core rod connected to the main airway of the core rod, and output it into the LED lamp tube from the core rod side airway connected to the main airway of the core rod. While supplying gas, the operator heats the LED lamp tube through the heating blocks on both sides of the LED lamp tube until the tube wall is melted, and then the pressing molds on both sides of the lamp tube are closed, so as to flatten and seal the lamp tube. The input of nitrogen can prevent the chip in the lamp tube from being damaged due to heat when the lamp tube is heated. When one end of the lamp tube is sealed, the operator first loosens the locking cap and pulls the lamp tube out of the core rod. Then the operator turns it upside down on the core rod and seals it in a similar way to the above. However, before sealing, the lamp tube is first evacuated with a vacuum pump to extract the nitrogen in the lamp tube, and argon is input from the opening on the seal seat. The argon is input from the gas transmission channel in the seal seat and output from the core rod side airway to the lamp tube. Then the sealing operation is performed through the above-mentioned heating and sealing methods.

[0036] Preferably, a support ring 11 connected to the accommodating groove is provided in the accommodating groove, and the sealing ring is located above the support ring.

[0037] Preferably, a handle 12 fixedly connected to the locking cap is disposed on the outer side of the locking cap, and the locking cap is threadedly connected to the sealing seat body.

[0039] Preferably, a ventilation groove 13 is provided on the bottom surface of the core rod, and a ventilation port 14 communicating with the ventilation groove is provided on the side wall of the ventilation groove.

[0040] The arrangement of the ventilation groove and the ventilation port enables the gas input from the gas transmission channel to be directly input into the lamp tube through the ventilation groove and the ventilation port.

[0041] Preferably, the gas transmission channel includes a vertical channel 15 arranged vertically and a transverse channel 16 communicating with the vertical channel.

[0042] Preferably, a bearing (not shown in the figure) is further provided above the extrusion plate.

[0043] The arrangement of the bearing reduces the friction between the locking cap and the extrusion when the locking cap rotates.

[0044] A vacuum inflatable pressure sealing machine including the above-mentioned inflatable pressure sealing seat includes a workbench 38, a rotating seat assembly 17 arranged on the surface of the workbench, a rotating disk 18 connected to the rotating seat assembly, an inflating device located in the middle of the rotating disk, and a plurality of pressure sealing seat assemblies 19 located at the edge of the rotating disk and circumferentially distributed around the rotating disk. The rotating seat assembly includes a fixed seat 20 fixedly arranged on the workbench, a rotating seat 21 located above the fixed seat and rotatable relative to the fixed seat, a plurality of rotating airways 22 are arranged on the rotating seat, and a fixed airway 23 corresponding to the rotating airway is arranged on the fixed seat. The arrangement of the fixed seat and the rotating seat realizes the rotating air supply function of the pressure sealing seat. Specifically, the rotating seat rotates to a predetermined position under the drive of the rotating disk. At this time, the fixed airway in the fixed seat is just connected with the rotating airway in the rotating seat, and the external air source can supply air to the lamp tube through the fixed airway, the rotating airway and the pipeline connecting the rotating airway and the pressure sealing seat (not shown in the figure), or vacuumize it through a vacuum pump. During the rotation of the rotating seat, since the rotating airway is disconnected from the fixed airway, it is impossible to supply air or evacuate. The rotating seat and the fixed seat are both provided with multiple circles of oil seal grooves 34 to achieve the sealing function of the fixed seat and the rotating seat. The vacuum filling and sealing machine also includes at least one group of heating components 24, at least one group of heating components in the heating components includes a molding component 25, the heating component is used to heat or anneal the lamp tube, and the molding component is used to mold and seal the lamp tube. The heating component and the molding component can be directly set on the workbench, or set on other fixing devices, and are located outside the heating component. The rotating disk is fixedly connected to the rotating seat, and the inflation device includes an inflation shell 26. An air inlet 27 and a plurality of inflation ports 28 corresponding to the pressure-sealing seat assembly are arranged on the side wall of the inflation shell. The inflation shell is fixedly arranged in the middle of the rotating disk. The pressure-sealing seat assembly includes a pressure-sealing seat 29. The main air channel of the core rod of the pressure-sealing seat is connected with the inflation port of the inflation shell through a pipeline (not shown in the figure), and the air delivery channel of the pressure-sealing seat is connected with the rotating air channel on the rotating seat through a pipeline (not shown in the figure). In actual use, the air inlet on the inflation device is connected with an external nitrogen gas source through a pipeline, and the fixed air channel on the fixed seat is connected with a vacuum pump and an argon gas source through a pipeline and a valve assembly, respectively, so as to achieve the purpose of inflating the lamp tube on the pressure-sealing seat with nitrogen, exhausting air and filling with argon. The heating assembly includes a heating block movable seat 30 and at least one support rod 31 arranged on the heating block movable seat. A heating block (not shown in the figure) is arranged on the support rod. In actual implementation, the heating block is mounted in a U-shaped groove at the top of the support rod through a connecting rod. The heating block is connected to the gas source and heats the lamp tube by burning. The lamp tube can also be heated by other heating methods such as electric heating, preferably by heating with fire. During heating, the heating block movable seat moves forward under the drive of an external linear drive device until the heating block reaches a predetermined position and heats the lamp tube. After heating is completed, the heating block movable seat returns to its original position under the drive of the external linear drive device.The die pressing assembly includes a die moving seat 32, dies 33 located on both sides of the support rod, and a die driving member disposed on the die moving seat and used to drive the die to move. The die moving seat is used to install the die, and the die is used to extrude and mold the lamp tube. Specifically, the die moving seat moves under the drive of an external linear drive device until it moves to a predetermined position. After the heating assembly completes heating the lamp tube, the dies on both sides move toward each other under the drive of the die driving assembly until the lamp tube located between the two dies is molded and sealed.

[0045] During the specific work, the operator first inserts one end of the lamp tube into the core rod of the press-sealing seat and locks it with a locking cap. After locking, the external driving motor drives the rotating seat to rotate, and then drives the rotating disk to rotate slowly. As the rotating disk rotates, the press-sealing seat assembly connected to the rotating disk also rotates until the press-sealing seat and the lamp tube on the press-sealing seat rotate to the position corresponding to the heating assembly. Subsequently, the heating block moving seat and the heating block of the heating assembly move toward the press-sealing seat under the drive of the external driving device until the heating block moves to the side of the lamp tube, and then the heating block heats the lamp tube. At the same time or after the heating is completed, the die moving seat and the die move to the predetermined position under the drive of the external driving device. After the heating of the lamp tube is completed, the heating block returns to its original position, and the die moves toward the lamp tube under the drive of the die driving component until the lamp tube is molded by the dies on both sides, and then the die and the die moving seat return to their original positions. During the heating process, the inflation device transports nitrogen to the lamp tube from the top of the press-sealing seat through a pipeline to protect the chip in the lamp tube. After the pressure seal of one end of the lamp tube is completed, the rotating disk drives the pressure seal seat to continue to move until the pressure seal seat rotates through each heating component in turn. The subsequent heating components anneal the lamp tube by gradually reducing the heating temperature. After the rotating disk rotates one circle and drives the lamp tube back to the initial position, the operator pulls the lamp tube out of the core rod, inserts the other open end into the core rod, and locks it with the locking cap. Then, the pressure seal of the other end of the lamp tube is achieved through a similar pressure sealing process as described above. Since the top of the lamp tube has been sealed during this pressure sealing process, the external gas source evacuates the lamp tube and fills it with argon gas from the bottom of the pressure seal seat through the fixed seat, the rotating seat and the pipeline.

[0046] In summary, the vacuuming, filling and sealing machine of the present invention simultaneously realizes the functions of filling, vacuuming and sealing the lamp tube, thereby greatly reducing the number of production equipment, improving the processing efficiency of the lamp tube, and reducing the production cost of the lamp tube.

[0047] As preferred embodiment 1, the pressure sealing seat assembly further comprises a mounting plate 35, one end of the mounting plate is connected to the rotating disk, and the other end of the mounting plate is connected to the pressure sealing seat.

[0048] As preferred embodiment 1, the die driving member includes a connecting rod 36 hinged on the die moving seat, and one end of the connecting rod is hinged to the die.

[0049] The setting of the connecting rod realizes the driving of the die. Specifically, one end of the connecting rod moves under the drive of an external driving mechanism. The driving device can be a linear motor or a cylinder, and its body is hinged on the die moving seat. When one end of the connecting rod moves, the connecting rod rotates around its axis, thereby driving the die to move.

[0050] As preferred embodiment 1, a connecting shaft 37 is connected to the rotating seat, and oil seal grooves 34 are provided on the surfaces of the rotating seat and the fixed seat.
