Description

Technical Field

[0001] This utility model relates to the technical field of lamp tube processing equipment, specifically to an automatic lamp tube tip-burning device. Background Technology

[0002] During the manufacturing process, some lamp tubes require the connection of an exhaust pipe to facilitate the gas filling operation. After the gas filling operation is completed, a tipping operation is required to obtain a single lamp tube, which involves cutting off the exhaust pipe connected to the lamp tube. Therefore, tipping is an important process step in lamp tube production.

[0003] However, the traditional process of burning lamp tips is usually done manually. This method is not only inefficient, but also easily affected by human factors, resulting in unstable product quality. In addition, manual burning tip operation may also pose certain safety hazards, which can easily cause personal injury and property damage. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an automatic lamp tip burning device.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An automatic lamp tip-burning device includes an installation platform, an installation plate rotatably mounted on the installation platform, and multiple sets of lamp clamps fixed on the installation plate. The installation plate has a circular structure, and the multiple sets of lamp clamps are installed sequentially and evenly spaced along the edge of the installation plate. The installation platform is also equipped with a drive motor for driving the installation plate to rotate. The drive motor drives the installation plate to rotate the interval angle between two adjacent sets of lamp clamps each time, so that the clamped lamps sequentially pass through the loading area, the melting area, and the unloading area.

[0007] The lamp clamp includes a fixed base for fixing to a mounting plate, two linkage rods rotatably mounted on the fixed base, a push rod fixedly connected to one of the linkage rods, and clamping arms respectively fixedly connected to the two linkage rods. The two linkage rods pass through the fixed base vertically, and each of the two linkage rods has a linkage tooth at its bottom. The two linkage teeth mesh with each other to form relative rotation. A tension spring is also provided between the bottoms of the two linkage rods. The tension spring drives the two linkage rods to rotate inward relative to each other, thereby clamping the two clamping arms together. When the push rod is pushed outward, the two linkage rods rotate outward relative to each other, thereby causing the two clamping arms to separate.

[0008] In this utility model, the two clamping arms extend horizontally in a direction away from the mounting plate, and the extended ends of the clamping arms are also provided with clamping plates. The clamping plates on the two clamping arms are arranged opposite to each other, and the inner side of the clamping plates is also provided with clamping grooves corresponding to the outline of the lamp tube.

[0009] Furthermore, a positioning device is provided below the clamping plate in the feeding area. The positioning device includes a positioning seat fixed on the installation platform, a support rod connected to the top of the positioning seat, and a positioning rod set on the top of the support rod. The positioning rod is provided with a positioning groove. When feeding, the exhaust pipe at the bottom of the lamp tube is placed in the positioning groove, and the bottom end of the lamp tube abuts against the top surface of the positioning rod to form a positioning.

[0010] Furthermore, one end of the positioning rod extends vertically downward to a connecting part, and the connecting part is provided with an elongated hole extending in the vertical direction. During installation, it is connected and fixed to the support rod by passing a screw through the elongated hole. The elongated hole is used to change the fixed height of the positioning rod.

[0011] Furthermore, the positioning seat includes a movable seat fixed on the mounting platform, a slide rod horizontally arranged on the movable seat, a slider slidably engaged with the slide rod, and a telescopic rod installed on the movable seat. The bottom of the support rod is adjustablely fixed on the slider. The fixed end of the telescopic rod is connected to one side of the movable seat, and the telescopic end of the telescopic rod is connected to one side of the slider. The telescopic rod drives the slider to move along the slide rod. After the lamp tube is loaded, the telescopic rod drives the slider to move backward. After the mounting plate rotates once, the telescopic rod drives the slider to move forward.

[0012] Furthermore, the movable seat is also provided with a limiting screw. The limiting screw is threaded to the front end of the movable seat and parallel to the slide bar. One end of the limiting screw abuts against the slider to form a limit. The distance between the limiting screw and the slider is adjusted by rotating the limiting screw.

[0013] This utility model has the following advantages and beneficial effects:

[0014] By rotating a circular mounting plate on the mounting platform, multiple lamp holders are sequentially installed along the edge of the mounting plate. The mounting plate drives the lamp holders to pass through the loading area, the melting area, and the unloading area in sequence, so that the lamps on the lamp holders complete the tipping operation in sequence. This not only achieves the goal of semi-automated production and improves the tipping efficiency of lamps, but also improves the consistency of lamps and ensures product quality. Moreover, in the loading area, workers only need to remove the lamps that have completed the tipping operation, and then fix and position the untipped lamps using lamp holders and positioning devices. The work is simple, low-intensity, and avoids safety hazards. Attached Figure Description

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0023] like Figures 1 to 4As shown, this embodiment discloses an automatic lamp tipping device, including an installation platform 1, an installation plate 2 rotatably mounted on the installation platform 1, and multiple sets of lamp clamps 3 fixed on the installation plate 2. The installation plate 2 has a circular structure, and the multiple sets of lamp clamps 3 are installed sequentially and evenly at intervals along the edge of the installation plate 2. The installation platform 1 is also equipped with a drive motor for driving the installation plate 2 to rotate. The drive motor drives the installation plate 2 to rotate the interval angle between two adjacent sets of lamp clamps 3 each time, so that the clamped lamp passes through the loading area, the melting area, and the unloading area in sequence, thereby realizing the automatic tipping operation of the lamp. In addition, the position of the unloading area coincides with the position of the loading area, that is, the lamp returns to the loading area after being driven by the installation plate 2 to rotate one circle. The worker only needs to remove the lamp that has completed the tipping operation, and then fix and position the untipped lamp through the lamp clamps and positioning device for loading. The operation is simple.

[0024] Specifically, the lamp clamp 3 includes a fixed base 31 for fixing on the mounting plate 2, two linkage rods 32 rotatably mounted on the fixed base 31, a push rod 36 fixedly connected to one of the linkage rods 32, and clamping arms 33 respectively fixedly connected to the two linkage rods 32. The two linkage rods 32 pass through the fixed base 31 in a vertical direction. The bottom of the two linkage rods 32 is provided with linkage teeth 34. The two linkage teeth 34 mesh with each other to make the two linkage rods 32 rotate relative to each other. A tension spring 35 is also provided between the bottom of the two linkage rods 32. The tension spring 35 drives the two linkage rods 32 to rotate inward relative to each other, thereby clamping the two clamping arms 33 together. When the push rod 36 is pushed outward, the two linkage rods 32 can rotate outward relative to each other, thereby causing the two clamping arms 33 to separate from each other, which facilitates loading and unloading.

[0025] In this embodiment, the two clamping arms 33 extend horizontally away from the mounting plate 2. The extended ends of the clamping arms 33 are also provided with clamping plates 37. The clamping plates 37 on the two clamping arms 33 are arranged opposite to each other. The inner side of the clamping plate 37 is also provided with a clamping groove 370 corresponding to the outline of the lamp tube. Preferably, the clamping groove 370 extends vertically so that the lamp tube is clamped and faces the vertical direction.

[0026] Furthermore, to ensure that the lamp tube is in the same position each time it is clamped, a positioning device 4 is provided directly below the clamping plate 37 in the feeding area. The positioning device 4 includes a positioning seat 41 fixed on the mounting platform 1, a support rod 42 connected to the top of the positioning seat 41, and a positioning rod 43 set on the top of the support rod 42. The positioning rod 43 has a positioning groove 430 corresponding to the outline of the exhaust pipe at the bottom of the lamp tube. During feeding, the exhaust pipe at the bottom of the lamp tube is placed in the positioning groove 430, and the bottom end of the lamp tube is pressed against the top surface of the positioning rod 43 to form a positioning. Specifically, one end of the positioning rod 43 extends vertically downward with a connecting part 431. The connecting part 431 has an elongated hole 432 extending in the vertical direction. During installation, the screw passes through the elongated hole 432 and is connected and fixed to the support rod 42. The fixed height of the positioning rod 43 can be changed through the elongated hole 432, thereby improving practicality.

[0027] Furthermore, when the lamp tube is clamped, the rotation of the mounting plate 2 will cause the positioning rod 43 to interfere with the exhaust pipe on the lamp tube. Therefore, the positioning seat 41 needs to move the support rod 42 back and forth to avoid the lamp tube. The positioning seat 41 includes a movable seat 411 fixed on the mounting platform 1, a slide rod 412 horizontally arranged on the movable seat 411, a slider 413 slidably engaged with the slide rod 412, and a telescopic rod 414 installed on the movable seat 411. The bottom of the support rod 42 is adjustablely fixed on the slider 413, and the telescopic rod 414... The fixed end of the telescopic rod 414 is connected to one side of the movable seat 411, and the telescopic end of the telescopic rod 414 is connected to one side of the slider 413. The telescopic rod 414 drives the slider 413 to move along the slide rod 412, thereby driving the support rod 42 to move back and forth, thereby driving the positioning rod 43 to disengage from the lamp tube and avoid dryness. Preferably, the telescopic rod 414 is a pneumatic push rod 36. After the lamp tube is loaded, the telescopic rod 414 drives the slider 413 to move backward. After the mounting plate 2 completes one rotation, the telescopic rod 414 drives the slider 413 to move forward.

[0028] Furthermore, in order to enable the slider 413 to move to a specific position, a limiting screw 415 is provided on the moving seat 411. The limiting screw 415 is threadedly engaged with the front end of the moving seat 411 and parallel to the sliding rod 412. One end of the limiting screw 415 abuts against the slider 413 to form a limit. By rotating the limiting screw 415, the distance between the limiting screw 415 and the slider 413 can be adjusted, thereby changing the moving position of the slider 413.

[0029] In this embodiment, the melting zone is equipped with a heating element 5 for melting the exhaust pipe at the bottom of the lamp tube and a leveling element 6 for leveling the bottom of the lamp tube. After the heating element 5 melts the exhaust pipe at the bottom of the lamp tube, the leveling element 6 flattens the bottom of the lamp tube. Further, the leveling element 6 includes a horizontal moving mechanism 61, a vertical moving mechanism 62, and a pressing rod 63. The vertical moving mechanism 62 is mounted on the horizontal moving mechanism 61, and the pressing rod 63 is mounted on the vertical moving mechanism 62. The vertical moving mechanism 62 drives the pressing rod 63 upward so that the top of the pressing rod 63 presses against the bottom of the lamp tube to achieve the leveling operation. After leveling, it is reset.

[0030] In this embodiment, multiple lamp tubes can be clamped on the clamping plate 37, and multiple sets of lamp tipping devices 5 and leveling devices 6 can be sequentially arranged in the lamp tipping area, thereby improving the lamp tipping efficiency.

[0031] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
