Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric tube welding, in particular to a photoelectric tube welding fixing tool. Background Art

[0002] A phototube is an electronic device that converts light signals into electrical signals. It uses the photoelectric effect to convert incident light energy into a current or voltage output. Phototubes are widely used in optical measurement, communication systems, and scientific experiments. Soldering the pins of a phototube requires a fixture to secure them.

[0003] For example, a photoelectric tube welding fixture disclosed in the authorization announcement number CN220217323U includes a counterweight base and a fixing clamp, wherein the fixing clamp includes a clamping arm, a pin shaft, and a torsion spring. The clamping arms are two, and are hinged to each other by the pin shaft so that one end of the hinged two clamping arms forms a clamping opening for clamping the photoelectric tube, and the other end forms a driving end for driving the clamping opening and closing. The torsion spring is mounted on the pin shaft and abuts against the inner wall surfaces of the two clamping arms on the side close to the driving end. After adopting the above technical solution, the beneficial effect of the utility model is as follows: the photoelectric tube welding fixture clamps the photoelectric tube to be welded through the openable and closable clamping opening on the fixing clamp, so as to ensure that the position of the photoelectric tube is fixed during welding, thereby facilitating the welding operation of the photoelectric tube.

[0004] Although the above patent can clamp the photoelectric tube to be welded to ensure that the position of the photoelectric tube is fixed during welding, it cannot solve the problem of fume generated during the welding process. The fume contains a large amount of volatile chemical particles. During large-scale processing, the chemical particles evaporate into the air, which will affect the health of workers. Utility Model Content

[0005] The purpose of the utility model is to provide a photoelectric tube welding fixing device to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A photoelectric tube welding fixture, comprising

[0008] A base, wherein a placement slot is provided in the middle of the top of the base, a plurality of negative pressure holes are regularly provided between the upper and lower ends of the placement slot, and clamping mechanisms are provided on both sides of the base close to the placement slot;

[0009] A mounting seat, the mounting seat is arranged at the middle of the bottom end of the base, and the upper and lower ends of the mounting seat are provided with filtering mechanisms;

[0010] The four corners of the bottom end of the base are each provided with supporting feet, and the bottom ends of the four supporting feet are each provided with a vacuum suction cup.

[0011] Preferably, the clamping mechanism includes a fixing seat, which is symmetrically arranged on the outside of both sides of the upper end of the base located at the placement groove, and a guide rod is movably installed in the middle of the fixing seat, and one end of the guide rod passes through the fixing seat and is fixedly connected to a clamping plate;

[0012] Preferably, a retaining ring is provided on the outside of the other end of the guide rod, and a spring is provided between the retaining ring and the fixing seat located on the outside of the guide rod;

[0013] Preferably, the filtering mechanism includes a suction pump, which is arranged below the middle of the mounting seat, with the suction end of the suction pump passing through the middle of the mounting seat, and an activated carbon filter is arranged just above the top of the mounting seat;

[0014] Preferably, the filtering mechanism further comprises a threaded ring, which is provided at the top outer ring of the mounting seat, and is threadedly connected to the inner wall of the lower middle portion of the base, and a gasket is provided at the bottom outer ring of the mounting seat near the activated carbon filter;

[0015] Preferably, a plurality of paddles are provided at an outer ring of the bottom end of the mounting seat with equal arcs.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This photoelectric tube welding fixture is used in conjunction with a suction pump, a negative pressure hole and an activated carbon filter. During welding, the generated fume is sucked in from the negative pressure hole on the placement tank and then filtered by the activated carbon filter. The particulate matter in the fume is adsorbed, and the clean air passes through the activated carbon filter and is discharged from the air outlet of the suction pump. In this way, while the photoelectric tube body is adsorbed by negative pressure, the fume can also be filtered, thereby achieving the purpose of dual use of one machine.

[0018] 2. This photoelectric tube welding fixing tool is used in conjunction with a suction pump, a negative pressure hole and a clamping plate. When the photoelectric tube is placed, the photoelectric tube body opens the clamping plates on both sides. When the clamping plates move, the guide rod stretches the spring and the elastic force of the spring clamps the photoelectric tube body in the opposite direction. Then the suction pump is started and absorbs the lower end surface of the photoelectric tube body through the negative pressure hole. This fixing method is faster and more adaptable.

When placed, the photoelectric tube body stretches the clamping plates 7 on both sides. When the clamping plates 7 move, the guide rod 6 stretches the spring 9, and the elastic force of the spring 9 clamps the photoelectric tube body in the opposite direction. Then the suction pump 10 is started, and the suction pump 10 adsorbs the lower end surface of the photoelectric tube body through the negative pressure hole 3.
