Description

Technical Field

[0001] The utility model relates to the technical field of bellows welding, in particular to a self-adjusting bellows welding AOI monitoring device. Background Art

[0002] Welded bellows is a new type of component that has emerged in recent years at home and abroad. It can generally be used as a sensitive component, sealing component, isolation medium, pipeline connection and temperature compensator, etc. In addition to the advantages of pressure resistance, temperature resistance, corrosion resistance and good sealing, it has two outstanding advantages over traditional formed bellows: large deformation and long service life.

[0003] The corrugated pipe is a pipe with a regular wave shape. Commonly used corrugated pipes are made of carbon steel, stainless steel, steel lined with plastic or aluminum. The corrugated pipe is mainly used in occasions with irregular bends, expansion and contraction, which are not convenient for pipe installation with fixed elbows. It is suitable for connecting pipes to pipes or pipes to equipment.

[0004] When the existing bellows are automatically welded using a welding machine, in order to ensure that the welding gun is accurately aligned with the weld, an industrial AOI monitoring camera is generally used in conjunction. The AOI monitoring camera observes and photographs the weld in real time through the lens, and transmits the data to the computer for processing. The computer can detect welding defects by analyzing the weld image, image processing and other technologies, find possible problems and deal with them. At the same time, the AOI monitoring camera can also assist the welder in welding operations. During the welding process, the welder needs to accurately locate the weld to ensure the welding quality. The AOI monitoring camera can track the position and shape of the weld in real time, assist the welder in positioning and adjustment, and improve welding accuracy and efficiency.

[0005] Since the bellows will cause the surrounding temperature to rise during welding, excessively high temperature will have a negative impact on the electronic components inside the camera, such as reducing sensitivity, increasing noise, etc., and may cause permanent damage to the components. Therefore, a heat dissipation device (such as a cooling fan) is generally provided on the AOI monitoring camera for heat dissipation. However, the cooling fan needs to be manually adjusted according to the actual ambient temperature to achieve good heat dissipation for the AOI monitoring camera, which is rather troublesome. Therefore, the present application provides a self-adjusting bellows welding AOI monitoring device to meet the demand. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: Reference Figure 1 A self-adjusting bellows welding AOI monitoring device shown includes an AOI monitoring camera 1 and a self-adjusting heat dissipation unit, which can automatically control the heat dissipation effect of the AOI monitoring camera 1 according to the external environment temperature;

[0025] like Figure 1 He Ru Figure 2 As shown, the self-adjusting heat dissipation unit includes a wrapping cover that completely wraps the AOI surveillance camera 1 except for the wiring end face, the installation end face and the camera end face, the wrapping cover includes an upper cover body 2 and a cylindrical hollow cover 5 that is detachably installed on the lower end of the upper cover body 2, the upper end of the upper cover body 2 is provided with a plurality of air outlets with filter screens 3 installed, and the inner cavity of each air outlet is provided with a heat dissipation fan 4, the outer wall of the upper cover body 2 is provided with a hollow tube 6 made of heat conductive material, and the inner cavity of the hollow tube 6 is provided with a low boiling point liquid, the upper end of the hollow tube 6 is provided with an air outlet pipe 7, and the inner cavity of the air outlet pipe 7 is sealed and slidably provided with a gear rod 8, a voltage regulator 10 is fixed on the outer wall of the hollow tube 6, and a plurality of transmission teeth 9 are provided on the outer wall of the adjusting knob on the voltage regulator 10 in the shape of a round table, the transmission teeth 9 are gear-connected with the gear rod 8, and the voltage regulator 10 is electrically connected with the plurality of heat dissipation fans 4.

[0026] When in use, the AOI monitoring camera 1 and the cooling fan 4 are powered on, and the welding machine is used for welding. When the ambient temperature around the AOI monitoring camera 1 rises, the external heat is transferred to the low-boiling-point liquid inside through the hollow tube 6 made of heat-conducting material, and the internal low-boiling-point liquid vaporizes. The air pressure inside the hollow tube 6 increases, which will cause the gear rod 8 to move outward, and the gear rod 8 moving upward drives the voltage regulating knob on the voltage regulator 10 to rotate, thereby increasing the voltage across the cooling fan 4, and then speeding up the fan blades, thereby improving the heat dissipation effect of the AOI monitoring camera 1. When the external ambient temperature drops, the gas is liquefied, the air pressure inside the hollow tube 6 decreases, the gear rod 8 moves downward, and drives the voltage regulating knob to rotate in the opposite direction, and the speed of the cooling fan 4 decreases. The self-regulating heat dissipation unit can automatically adjust the speed of the cooling fan 4 according to the external ambient temperature, and can form a good heat dissipation for the AOI monitoring camera 1.

[0027] The AOI monitoring camera 1 is partially wrapped by the wrapping cover to form an internally sealed airflow channel, that is, air is taken in from the bottom of the hollow cover 5 and discharged from the air outlet arranged at the upper end of the upper cover body 2, so that the airflow can be concentrated to take in from the bottom of the hollow cover 5, and the AOI monitoring camera 1 is cooled from bottom to top, which can enhance the heat dissipation effect of the AOI monitoring camera 1.

[0028] It should be noted that the lens barrel of the AOI monitoring camera 1 is located in the inner cavity of the hollow cover 5 .

[0029] As a preferred implementation in this embodiment, Figure 5 As shown, the voltage regulator 10 is connected to the main line, and a plurality of cooling fans 4 are connected in parallel with the main line. When one of the cooling fans 4 fails, the other cooling fans 4 will continue to work to dissipate heat.

[0030] As a preferred implementation mode of this embodiment, not shown in the figure, the upper cover body 2 and the hollow cover 5 are made of heat-insulating materials, the purpose of which is to isolate part of the external heat and prevent the internal temperature of the AOI monitoring camera 1 from rising rapidly.

[0031] As a preferred implementation in this embodiment, which is not shown in the figure, the hollow cover 5 is transparent to avoid affecting the camera light of the AOI monitoring camera 1.

[0032] It should be noted that the hollow cover 5 is made of silicate glass material, which is transparent and has a good heat insulation effect.

[0033] As a preferred implementation in this embodiment, Figure 3 He Ru Figure 4 As shown, a plurality of columns 11 are circumferentially arranged on the upper end of the hollow cover 5, and a socket adapted to the columns 11 is arranged on the bottom surface of the annular lower end of the upper cover body 2, and a plurality of elastic sheets 12 are circumferentially arranged on the inner ring wall of the upper end of the hollow cover 5, and a semicircular positioning protrusion 13 is arranged on the outer end surface of each elastic sheet 12, and a positioning groove adapted to the positioning protrusion 13 is arranged on the inner ring wall of the lower end of the upper cover body 2.

[0034] When the camera head of the AOI monitoring camera 1 needs to be adjusted, the outer wall of the hollow cover 5 can be held to push it outward. The positioning protrusion 13 deforms the elastic sheet 12 under the action of the pulling force, and finally the positioning protrusion 13 can be moved out of the positioning groove, and the hollow cover 6 is pulled off from the upper cover body 2. At this time, it can be adjusted by rotating the camera head. After the adjustment is completed, the column 11 is connected to the jack, and the positioning protrusion 13 is moved into the positioning groove to complete the installation. The hollow cover 5 is convenient for disassembly and assembly of the hollow cover 5 and the upper cover body 2 through the arrangement of the column 11, the elastic sheet 12 and the positioning protrusion 13.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
