Description

Technical Field

[0001] The invention relates to the technical field of arc tube production equipment, in particular to a gas discharge light source exhaust automatic lamp cutting system. Background Art

[0002] In the manufacturing of arc tubes for metal halide lamps, the previous process required workers to wear glasses and use a torch to cut the arc tube, and then sinter the cut head. This process has extremely high requirements for personnel, and a long period of practice is required before taking up the job. It also limits the uniqueness of personnel in the sub-process, increasing the company's labor costs. The appearance and internal inflation pressure of the produced arc tubes are also difficult to ensure consistency, affecting the performance of the arc tubes. Employees who use torches to cut lamps for a long time will cause great damage to their eyes. Summary of the invention

[0005] The staff fixes the arc tube with pilled mercury on the fixed assembly. The first drive device is used to control the movement of the second bracket to move the finger assembly on the second bracket to the bottom of the arc tube. Then the second drive device is used to drive the second bracket to rise, so that the position of the finger assembly is raised to the arc tube and clamps the arc tube. The third drive device is used to drive the burning and cutting assembly to approach the exhaust rod of the arc tube and cut the exhaust rod. After cutting, the burning and cutting assembly continues to work, and the first drive device drives the second bracket to move and move the finger assembly to the bottom of the flattening assembly. The flattening assembly flattens the cutting head. Then the third drive device drives the burning and cutting assembly to retreat and reset. After the arc tube cools down for a period of time, the arc tube is removed, and the second drive device descends and resets to complete the processing of a group of arc tubes.

[0006] Furthermore, in order to clamp the arc tube, the fixing assembly includes an elastic clamp, a locking nut and a rubber clamping block. The rubber clamping block is arranged in the elastic clamp. The rubber clamping block is axially provided with a through hole that cooperates with the exhaust rod of the arc tube. The locking nut cooperates with the elastic clamp thread to press the rubber clamping block to clamp the exhaust rod of the arc tube.

[0007] The staff inserts the arc tube exhaust rod into the through hole of the rubber clamping block, and compresses the elastic collet by tightening the locking nut (it can be tightened manually or by the cylinder extending and retracting to drive the locking nut to rotate). After the elastic collet is compressed, the through hole deforms and tightly holds the exhaust rod to prevent the arc tube from falling off the fixed assembly when cutting the exhaust rod.

[0008] Furthermore, the flattening assembly includes a flattening cylinder and a flattening head arranged at the output end of the flattening cylinder. The flattening cylinder extends and contracts to drive the flattening head to press the molten cutting head to make it smooth. The flattening head can be made of heat-resistant and stable metal materials such as copper rods.

[0009] Furthermore, the first driving device includes a slide plate arranged on the output end of the first cylinder and a connecting plate arranged on the slide plate, and the second bracket is arranged on the upper end of the connecting plate.

[0010] Furthermore, the second driving device includes a second cylinder disposed on the slide plate, and a guide rail and a slider disposed on the side wall of the connecting plate, the slider is slidably connected to the guide rail, the upper end of the slider is fixedly connected to the second bracket, the axis of the output end of the second cylinder is parallel to the axis of the guide rail, and the output end of the second cylinder is fixedly connected to the second bracket. The second cylinder is disposed on the slide plate, and the first cylinder extends or contracts to drive the second cylinder to move, and when the second cylinder extends or contracts, the second bracket rises or falls, and the slider slides along the guide rail.

[0011] Furthermore, the clamping finger assembly includes pneumatic fingers, and the output end of the cylinder finger is provided with a clamping plate that matches the side wall of the arc tube body. The arc tube is clamped by arranging two clamping plates on the pneumatic fingers to clamp the two side walls of the arc tube body.

[0012] Furthermore, a guide groove inclined downward is provided on one side of the pneumatic finger, and a collection box is provided below the guide groove. The processed arc tube is drawn into the collection box through the guide groove.

[0013] Furthermore, the burning and cutting assembly includes a torch and a fixed plate, a plurality of torches are arranged on the fixed plate, and the positions and quantities of the torches correspond to the fixed assembly one by one, and the third driving device includes a third cylinder, a cylinder body of the third cylinder is arranged on the second bracket, and an output end of the third cylinder is fixedly connected to the fixed plate. The output end of the third cylinder extends or contracts to drive the fixed plate to move, thereby driving the torch arranged on the fixed plate to move.
