Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a device for installing a light-scattering film on a lamp tube. Background Art

[0002] Diffuser film is a thin film material that converts direct light into diffuse light. It effectively disperses direct light into diffuse light, making the light distribution more uniform and reducing light damage caused by excessive direct light.

[0003] To evenly distribute the light produced by a lamp, a diffuser film is typically installed inside the lamp. This allows the light generated by the light-emitting units within the lamp to be directly diffused through the diffuser film before being emitted. Therefore, installing diffuser film is a crucial step in the lamp production and assembly process.

[0004] In the existing technology, the installation of the diffuser film is mainly completed manually or with the use of simple jigs. These methods are all purely manual operations, and the installation efficiency of the diffuser film is very low. It takes more than 120 seconds to install the diffuser film on each lamp tube. After installation, the diffuser film is prone to wrinkles, making it difficult to operate when assembling the lamp tube in the next process.

[0005] Therefore, it is necessary to study a solution to solve the above problems. Utility Model Content

[0026] The base 10 is provided with a clamping assembly 60 and a support assembly 70. The clamping assembly 60 is used to clamp and secure the lamp tube, while the support assembly 70 is used to support the pull rod 40. Specifically, the clamping assembly 60 includes a clamping base 61, a clamping arm 62, and a drive cylinder 63. The clamping base 61 is fixed to the surface of the base 10, and a clamping groove 601 is recessed on the surface of the clamping base 61 to match the lamp tube. The clamping arm 62 is provided on the clamping base 61 so as to swing back and forth. The clamping arm 62 swings back and forth to open and close the opening of the clamping groove 601. One end of the drive cylinder 63 is hinged to the base 10, and a piston rod 631 extends from the other end of the drive cylinder 63. The end of the piston rod 631 is hinged to the clamping arm 62. In this embodiment, the clamping arm 62 is L-shaped, and the drive cylinder 63 is a pneumatic cylinder, which can quickly clamp the lamp tube in the clamping groove 601. The support assembly 70 includes a support base 71 and a pulley 72. The support base 71 is disposed on the surface of the base 10. The surface of the support base 71 is provided with a recessed groove 701 for the pull rod 40 to pass through. The pulley 72 is rotatably disposed in the recess 701 and contacts the pull rod 40 to facilitate the movement of the pull rod 40. Furthermore, the base 10 is provided with a guide rail 11, which extends laterally.

[0027] The electric control box 20 is mounted on the machine base 10 . In this embodiment, the electric control box 20 is equipped with a PLC integrated machine 21 having a touch-screen human-machine interface 211 for setting various parameters. The aforementioned drive cylinder 63 is electrically connected to the electric control box 20 .

[0028] The movable seat 30 can be arranged on the machine base 10 so as to be movable back and forth laterally. In this embodiment, the movable seat 30 is mounted on the guide rail 11 and moves back and forth laterally along the guide rail 11, so that the movable seat 30 moves smoothly and steadily.

[0029] The pull rod 40 is against the supporting assembly 70 , one end of the pull rod 40 is fixedly connected to the movable seat 30 and moves back and forth laterally with the movable seat 30 , and the other end of the pull rod 40 is provided with a material clamp 41 for clamping the diffusing film.

[0030] The drive mechanism 50 is disposed on the machine base 10 and is electrically connected to the electrical control box 20. The drive mechanism 50 drives the movable base 30 to move back and forth laterally. Specifically, the drive mechanism 50 includes a drive motor 51, a driving pulley 52, a plurality of driven pulleys 53, and a transmission belt 54. The drive motor 51 is fixed to the machine base 10, the driving pulley 52 is mounted on the output shaft of the drive motor 51, and the plurality of driven pulleys 53 are rotatably mounted on the machine base 10. The transmission belt 54 is wound around the driving pulley 52 and each of the driven pulleys 53. The transmission belt 54 is fixedly connected to the movable base 30. The rotation of the transmission belt 54 drives the movable base 30 to move back and forth laterally.

[0031] The working principle of this embodiment is described in detail as follows:

[0032] First, place the lamp on the external bracket, and set the diffuser film guide curling assembly on the external bracket. The diffuser film guide curling assembly is located next to the tail end of the lamp, and the front end of the lamp is embedded in the clamping groove 601. Then, step on the foot switch (not shown) to start the device. First, the clamping assembly 60 clamps the front end of the lamp, and then the driving mechanism 50 works to make the pull rod 40 move horizontally and extend into the lamp. When the pull rod 40 passes through the rear end of the lamp, the diffuser film guide curling assembly is inserted into the lamp. The light film is pre-rolled and its end is placed on the material clamp 41, and the material clamp 41 clamps the end of the light-diffusing film. Then, the foot switch is stepped on again, and the driving mechanism 50 is operated to make the pull rod 40 move horizontally and move out of the front end of the lamp tube. The light-diffusing film is pulled into the lamp tube as the pull rod 40 moves. The parameters can be adjusted on the touch human-machine interface 211 as needed to make the light-diffusing film reach the required position. Finally, the clamping component 60 is released, and the lamp tube is removed from the external bracket. The light-diffusing film installation operation is completed.

[0033] Compared with the existing technology: this equipment consists of a machine base, an electric control box, a movable base, a pull rod and a driving mechanism. The driving mechanism uses the movable base to drive the pull rod to move back and forth, so that the pull rod pulls the heat dissipation film into the lamp tube. The overall equipment structure is simple and easy to operate, which greatly improves the production efficiency of installing the light-scattering film. The whole process only takes 20 seconds to complete, and there will be no defects such as wrinkles and improper installation, which ensures the yield and the manufacturing cost is relatively low.
