Technical Field

[0001] This utility model belongs to the technical field of fixing components of lighting devices, specifically an automated and rapid lamp holder bonding device. Background Technology

[0002] A hollow cathode lamp mainly consists of an anode, a hollow cathode, a glass tube filled with low-pressure inert gas, and a matching lamp holder. Hollow cathode lamps play a crucial role in atomic analysis; therefore, extremely high requirements are placed on the bonding between the lamp cover and the lamp holder. The bonding must be firm and reliable to ensure that it does not loosen or detach during prolonged use.

[0003] Existing lamp holder bonding devices require human judgment to align the lamp holder and bond the lampshade. In mass production scenarios, the accuracy of human judgment decreases, leading to misalignment between the lampshade and the lamp holder, and weakened adhesion. Collisions caused by improper placement during gel solidification can also cause loosely bonded lampshades and lamp holders to shift. Utility Model Content

[0030] Workflow:

[0031] According to the lampshade 205 to be bonded, select the first claw part 2031 and the second claw part 2032 of the claw 203, wherein the first claw lampshade joint part 2040 of the first claw part 2031 and the second claw lampshade fitting part 2041 of the second claw 2032 match the outer peripheral dimensions of the lampshade 205; the operator next to the workbench 3 places the lampshade 205 with the interface to be bonded facing down in the lampshade placement slot 201, and places the lamp holder 206 with the gel coated on the bonding interface in the lamp holder placement slot 202 with the gel coated side facing up;

[0032] The rotary table 2's base plate 204 rotates clockwise. After the positioning laser 15 collects the positioning signal, if there is no lampshade in the gripping device 9, the system enters the gripping process; if there is a lampshade in the gripping device 9, the system enters the bonding process. Subsequently, the bonded lampshade rotates back to the worktable 3 with the rotary table 2 and is collected by the operator. Then, the new lamp holder 206 and lampshade 205 are placed into the lamp holder placement slot 202 and lampshade placement slot 201, respectively.

[0033] The grasping process is as follows: when the lampshade placement slot 201, in which the lampshade is placed, moves to the bottom of the grasping device 9, the lifting motor 7 is operated to drive the screw of the lifting screw assembly 8 to rotate, causing the grasping device 9 to move down as a whole. When the grasping fingers of the grasping device 9 move to the grasping height, the grasping cylinder 903 is operated to tighten the grasping fingers 906 inward to grasp. After grasping, the lifting motor 7 is rotated in the opposite direction to raise the grasping device to the highest position, and then the rotary table base plate 204 continues to rotate clockwise.

[0034] The bonding process is as follows:

[0035] The system determines whether the lamp holder 206 is placed vertically by checking whether the value fed back to the control system by the laser aligner 14 fluctuates significantly during the alignment process. If the value fluctuates significantly, the bonding process and the next gripping process are skipped. After the operator sees that the lamp cover 205 is not bonded to the lamp holder 206, the operator shakes the lamp holder 206 to align it and continues to the next cycle.

[0036] If the value does not fluctuate significantly, the lifting motor 7 is driven to lower the lampshade 205 held by the gripping device 9, inserting the lampshade 205 between the first claw lampshade joint 2040 and the second claw lampshade joint 2041 of the gripper 203, so that the adhesive joint of the lampshade 205 contacts the adhesive joint of the lamp holder 206; then the rotation motor 901 of the gripping device 9 is started to rotate the lampshade 205, ensuring a firm bond; then the control system operates the pneumatic solenoid valve 207 to move the first claw cylinder 2035 and The second claw cylinder 2037 drives the first claw part 2031 and the second claw part 2032 to move inward, so that the first claw lampshade joint part 2040 and the second claw lampshade joint part 2041 clamp the lampshade 205; finally, the gripping finger 906 is released and the gripping device is raised and lowered to the highest movable point; the rotary table 2 continues to rotate clockwise, and the gripping device 9 and the lifting screw assembly 8 wait for the next gripping process; at the same time, the support claw 203, the lamp holder placement slot 202 and the lamp holder with the lampshade attached rotate together with the rotary table base plate 204.
