An automatic production line for energy-saving lamp tube beads

Abstract

An energy-saving lamp tube bead dispensing automatic production line comprises a workpiece conveying device. The workpiece conveying device is arranged on a rack and comprises conveying chains driving cyclically at the right side and the left side of the rack. The conveying chain is provided with a front sprocket and a rear sprocket. A strip-shaped conveying tube accommodating seat is fixed between the two conveying chains. A power device is arranged to drive the conveying chains to drive, the upper part of the conveying chain is a driving working surface, and a lamp tube workpiece in need of bead dispensing lies on the tube accommodating seat. When the lamp tube workpiece in need of bead dispensing is placed on the tube accommodating seat, the bead dispensing place of the lamp tube workpiece faces upwardly, two or more than two sets of automatic bead dispensing devices are arranged on the driving working surface, and each automatic bead dispensing device comprises an ignition heating working position, a bead adding working position and a turning working position sequentially. A method of heating the bead dispensing place of the lamp tube workpiece is adopted, the bead and a high-temperature lamp tube are melted, combined and fixed, the combination is firm, the operation is convenient, the lamp tube bead dispensing efficiency is high, the operators are greatly reduced, and as no glue is needed for bead dispensing, the working environment is enhanced.

Description

technical field [0001] The invention relates to the bead dotting technology of a lamp tube, in particular to a bead dotting device for a lamp tube. Background technique [0002] Energy-saving lamps are divided into U-tube energy-saving lamps, spiral-tube energy-saving lamps, and straight-tube energy-saving lamps due to different lamp tube shapes. U-tube energy-saving lamps are divided into 2U, 3U, 4U, 5U, 6U, 8U and other types. Since the U-shaped tube energy-saving lamps above 2U are connected only by the lamp head, when installing the U-shaped tube energy-saving lamp, the human hand will often twist the back end of each U-shaped tube and apply a squeeze to each U-shaped tube. force, it is easy to cause the U-shaped tube to break or loosen from the lamp head. In order to solve this problem, generally, for U-shaped tube energy-saving lamps above 2U, beads need to be set between adjacent U-shaped tubes as supporting points, such as figure 1 As shown, it is a 3U lamp tube w...

[0003] The Chinese Utility Model Patent No. ZL201320417526.0 discloses an automatic bead dotting machine for lamp tubes, which includes a motion table, a transposition clamping mechanism, a glue dispensing mechanism, and a directional bead dosing mechanism. The transposition clamping mechanism includes The reversing mechanism, the lamp tube fixing clip, the lamp tube fixing clip is installed on the motion workbench, the glue dispensing mechanism, the directional bead pointing mechanism, and the reversing mechanism are arranged in sequence along the running track of the motion workbench On the side of the table, the moving workbench has at least a first station, a second station, and a third station, the first station is located at the relative position of the dispensing head of the dispensing mechanism, and the second The station is located at the relative position of the dotting head of the directional bead dosing mechanism, and the third station is located at the relative position of the reversing mechanism. This structure uses a glue dispensing mechanism to dispens glue at the bead spot of the lamp tube workpiece. On the one hand, the amount of glue produced is difficult to control, which often affects the combination of beads and lamp workpieces. In addition, the fluidity of the glue will cause the phenomenon of hanging glue, which will affect the product quality. In addition, the glue contains formaldehyde and benzene, which will affect the health of the operator. healthy
