Description

Technical Field

[0001] The utility model relates to the field of automobile manufacturing, in particular to a device for adjusting the vision of a welding robot. Background Art

[0002] The automobile dashboard crossbeam assembly is a key component in the automobile interior system. It is specifically installed in the front of the vehicle. The automobile dashboard crossbeam assembly also mounts many components such as the steering column, air conditioning, airbags, etc. The space is relatively compact and must conform to the direction of various wiring harnesses.

[0003] In order to mount other automotive components on the automotive instrument panel cross beam assembly, it is usually necessary to weld corresponding overlapping structures to support or bridge the automotive components. When welding overlapping structures on the automotive instrument panel cross beam assembly, due to the uneven sizes and large number of overlapping structures, especially small overlapping structures, they are easily affected by external factors and deflected during the welding process. Therefore, it is necessary to inspect the automotive instrument panel cross beam assembly after welding.

[0004] Existing detection devices usually use a robotic arm combined with a camera to approach the car dashboard beam assembly for shooting and monitoring. In order to assist the camera operation, it is usually necessary to equip a corresponding light source. These light sources are generally integrated into the detection device. However, since the light source generates a lot of heat when it emits light, if the heat cannot be dissipated in time, it will affect the light source itself or other components of the detection device. Utility Model Content

[0005] The purpose of this utility model is to provide a device for adjusting the vision of a welding robot to solve the problem that when the light source of the existing detection device emits light, it generates a large amount of heat but cannot dissipate the heat in time, which affects the light source itself or other components of the detection device. The specific technical solution is as follows:

[0006] A device for adjusting the vision of a welding robot includes a multi-axis robotic arm and a detection device connected to the multi-axis robotic arm. The detection device includes a shell and a camera connected to the shell. A raised portion is provided on the side of the shell, and an annular groove is provided on the bottom surface of the raised portion. A light strip is installed in the annular groove to cooperate with the camera for shooting. A metal ring is provided around the outer side of the raised portion.

[0007] Preferably, the light strip includes a flexible circuit board, a thermally conductive pad and an LED lamp, the LED lamp is electrically connected to the flexible circuit board, and the flexible circuit board is connected to the thermally conductive pad.

[0008] Preferably, the metal ring is connected to the thermally conductive gasket.

[0009] Preferably, the thermally conductive gasket is in a ring shape.

[0010] Preferably, a plurality of heat dissipation fins arranged at intervals are provided on the side surface of the metal ring.

[0011] Preferably, a threaded hole is provided in the annular groove, an opening is provided on the thermal conductive gasket, a bolt is provided in the annular groove, and the bolt passes through the opening and is connected to the bolt hole.

[0012] Preferably, thermally conductive adhesive is laid on the thermally conductive gasket, and the flexible circuit board is bonded to the thermally conductive adhesive.

[0013] The beneficial effects of the present invention are as follows: by arranging a metal ring around the outer side of the raised portion, the overall strength of the detection device can be enhanced and the camera can be protected; the flexible circuit board can be cooled by using a thermal pad in combination with the metal ring; and the heat dissipation area of the metal ring can be increased by arranging heat dissipation fins on the metal ring. When the robotic arm is swung, it will drive the flow of surrounding air to form local convection, which helps to accelerate the heat exchange between the surrounding air and the metal ring, thereby improving the heat dissipation efficiency to a certain extent.

[0014] Additional aspects and advantages of the present invention will be partially given in the description below, and partially will become apparent from the description below, or will be understood through the practice of the present invention. Of course, it is not necessary to achieve all of the advantages described above at the same time when implementing any product or method of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] When the light source of the existing detection device emits light, it generates a lot of heat and cannot dissipate the heat in time. In a high temperature environment, it will shorten the life of the light source itself or affect the normal operation of other components of the detection device. Figure 1-6 The present invention provides an embodiment to solve the above-mentioned problem, specifically comprising a multi-axis robotic arm 1 and a detection device 2 connected to the multi-axis robotic arm 1, the detection device 2 comprising a shell 21 and a camera 22 connected to the shell 21, a side surface of the shell 21 is provided with a protrusion 23, a bottom surface of the protrusion 23 is provided with an annular groove 231, a light strip 24 is assembled in the annular groove 231 to cooperate with the camera 22 for shooting, it is understandable that, since the sizes of various overlapping structures on the crossbeam assembly of the automobile instrument panel are uneven and there are many of them, even if the device may be equipped with additional lighting sources, there will still be some dark corners. At this time, if there is no light source to cooperate with the camera 22 for shooting, the picture shot or recorded by the camera 22 may not be clear, affecting subsequent detection. Therefore, it is necessary to set a light strip 24 that can rotate with the camera 22 in the detection device 2 to assist the camera 22 in shooting;

[0026] In some embodiments, the various overlapping structures on the above-mentioned automobile instrument panel crossbeam assembly have varying sizes and a large number of them. Some overlapping structures may deviate from the predetermined welding position due to poor welding quality. Even if the robotic arm can move according to the predetermined trajectory, there is still a risk of collision. Therefore, by providing a metal ring 25 around the outer side of the protrusion 23, the overall strength of the detection device 2 can be enhanced to protect the camera 22.

[0027] Preferably, the light strip 24 includes a flexible circuit board 241, a thermal pad 243 and an LED lamp 242. The LED lamp 242 is electrically connected to the flexible circuit board 241, the flexible circuit board 241 is connected to the thermal pad 243, and the metal ring 25 is connected to the thermal pad 243. It is understandable that since the LED lamp 242 in this embodiment is always on, this will cause the corresponding components to generate heat, affecting the life of the LED lamp 242. Therefore, it is necessary to dissipate heat for the LED lamp 242 when it is working. Preferably, the thermal pad 243 is annular. By designing the thermal pad 243 into an annular shape, it is adapted to the annular groove 231.

[0028] In some embodiments, the heat dissipation efficiency can be further improved by providing a plurality of spaced-apart heat dissipation fins on the side of the metal ring 25. It can be understood that the heat dissipation area of the metal ring 25 can be increased by providing heat dissipation fins. In this embodiment, when the robotic arm is swung, it may drive the flow of surrounding air to form local convection. This convection helps to accelerate the heat exchange between the surrounding air and the metal ring 25, thereby improving the heat dissipation efficiency to a certain extent.

[0029] Regarding the fixation of the light strip 24, specifically, a threaded hole is provided in the annular groove 231, an opening is provided on the thermal gasket 243, a bolt 26 is provided in the annular groove 231, the bolt 26 passes through the opening and is connected to the bolt 26 hole. Preferably, thermal conductive glue is laid on the thermal gasket 243, and the flexible circuit board 241 is bonded to the thermal conductive glue.

[0030] It should be noted that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Therefore, a feature designated as "first" or "second" may explicitly or implicitly include one or more of the aforementioned features.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
