Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a bulb welding device based on vision inspection and positioning. Background Technology

[0002] With the development of automobiles, the production volume of automotive signal lights has increased significantly. Existing automotive signal lights consist of a bulb and a lamp holder, which are manufactured independently. Therefore, after production, they need to be assembled through a welding station. The most crucial step in welding assembly is aligning the bulb and lamp holder. Currently, this is generally done manually: first, the lamp holder is fixed, then the bulb's position is manually adjusted to align with the lamp holder, and finally, welding equipment is used to weld the connection between the bulb and the lamp holder. However, this manual alignment method is inefficient. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a light bulb welding device based on vision detection and positioning to solve the above problems.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a light bulb welding device based on visual detection and positioning, including a lamp head fixing module, a bubble clamping and positioning module, a camera and a welding torch. After the lamp head of the signal light passes through the lamp head fixing module, the welding part of the lamp head is located on the lower side of the lamp head fixing module; the lens of the camera and the welding torch are both facing the welding part of the lamp head.

[0005] The foam clamping and positioning module includes a lower base, a sliding block, a lifting component, and a two-axis translation component. The lower base is located below the lamp head fixing module. The sliding block is slidably connected to the lower base through the two-axis translation component. The lifting component is located on the sliding block, and the end of the lifting component extends toward the lamp head fixing module. The end of the lifting component is provided with a clamping mechanism for clamping the foam.

[0006] Preferably, at least two cameras are arranged between the lamp head fixing module and the lower base, all cameras are located on the same horizontal plane and arranged around the welding part of the lamp head, and the lens angles of adjacent cameras are perpendicular to each other.

[0007] Specifically, multiple welding torches are arranged between the lamp head fixing module and the lower base, and are evenly distributed around the welding part of the lamp head.

[0008] It is worth noting that the lifting assembly includes a connecting seat, a lifting cylinder, a lifting guide rail, and a lifting slider. The connecting seat is connected to the sliding block, and the connecting seat is provided with a lifting guide rail that extends toward the lamp head fixing module. The lifting slider is slidably connected to the lifting guide rail. The lifting cylinder is disposed on the connecting seat, and the telescopic shaft of the lifting cylinder faces the lamp head fixing module and is connected to the lifting slider. The clamping mechanism is disposed on the lifting slider.

[0009] Optionally, the two-axis translation assembly includes an X-axis translation guide rail, an X-axis translation slider, and a Y-axis translation guide rail. The X-axis translation guide rail is disposed on the lower base, the X-axis translation slider is slidably connected to the X-axis translation guide rail, the Y-axis translation guide rail is disposed on the X-axis translation slider, and the sliding block is slidably connected to the Y-axis translation guide rail.

[0010] Specifically, the lamp holder fixing module includes an upper base, a pressure block, and a lower pressure cylinder. The upper base has a fixing hole, the telescopic shaft of the lower pressure cylinder extends downward and faces the fixing hole, and the pressure block is located at the end of the telescopic shaft of the lower pressure cylinder.

[0011] The beneficial effects of this invention are as follows: In the light bulb welding device based on vision detection and positioning, the light head is first fixed in position by the light head fixing module, then the bulb is clamped by the clamping mechanism, and then the bulb is moved to the vicinity of the light head by the two-axis translation component. At this time, the camera lens captures images of the area around the welding part of the light head and uploads them to the host computer to determine the distance between the welding part of the light head and the bulb, thus achieving vision detection. The two-axis translation component and the lifting component then continuously bring the bulb closer to the welding part of the light head, ultimately aligning the bulb with the light head, and then the welding torch can be driven to weld the area. This improves efficiency compared to manual alignment, thereby increasing the production volume of signal lights. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1-6 As shown, a light bulb welding device based on vision detection and positioning includes a lamp head fixing module 1, a bubble clamping and positioning module 2, a camera 3, and a welding torch 4. After the lamp head 51 of the signal light 5 passes through the lamp head fixing module 1, the welding part of the lamp head 51 is located on the lower side of the lamp head fixing module 1; the lens of the camera 3 and the welding torch 4 are both facing the welding part of the lamp head 51.

[0021] like Figure 1 and 2 As shown, the foam clamping and positioning module 2 includes a lower base 21, a sliding block 22, a lifting component 23, and a two-axis translation component 25. The lower base 21 is disposed below the lamp head fixing module 1. The sliding block 22 is slidably connected to the lower base 21 through the two-axis translation component 25. The lifting component 23 is disposed on the sliding block 22, and the end of the lifting component 23 extends toward the lamp head fixing module 1. The end of the lifting component 23 is provided with a clamping mechanism 24, which is used to clamp the foam 52.

[0022] In the aforementioned light bulb welding device based on vision detection and positioning, the light head 51 is first fixed in position by the light head fixing module 1. Then, the bulb 52 is clamped by the clamping mechanism 24, and the bulb 52 is moved to the vicinity of the light head 51 by the two-axis translation component 25. At this time, the camera 3 captures images of the area around the welding part of the light head 51 and uploads them to the host computer to determine the distance between the welding part of the light head 51 and the bulb 52, thus achieving vision detection. The two-axis translation component 25 and the lifting component 23 then continuously bring the bulb 52 closer to the welding part of the light head 51, ultimately aligning the bulb 52 with the light head 51. Then, the welding torch 4 can be driven to weld the area. This method improves efficiency compared to manual alignment, thereby increasing the production volume of the signal lights 5.

[0023] It is worth noting that, such as Figure 5 As shown, at least two cameras 3 are positioned between the lamp head fixing module 1 and the lower base 21. All cameras 3 are located on the same horizontal plane and arranged around the welding part of the lamp head 51, with the lenses of adjacent cameras 3 positioned perpendicular to each other. By using the lenses of the cameras 3 arranged at 90° angles in conjunction with the two-axis translation component 25, the distance between each camera 3 and one axis of the two-axis translation component 25 is identified, thereby controlling the translation of the bubble 52 on the horizontal plane. Since all cameras 3 are located on the same horizontal plane, only the image captured by one camera 3 is needed to obtain the current vertical distance between the bubble 52 and the lamp head 51. Combined with the lifting component 23, the vertical movement of the bubble 52 is controlled.

[0024] Preferred, such as Figure 5 As shown, multiple welding torches 4 are arranged between the lamp head fixing module 1 and the lower base 21, and are evenly distributed around the welding area of ​​the lamp head 51. By setting multiple welding torches 4, the efficiency of each welding operation can be improved.

[0025] Optional, such as Figure 3As shown, the lifting assembly 23 includes a connecting seat 231, a lifting cylinder 232, a lifting guide rail 233, and a lifting slider 234. The connecting seat 231 is connected to the sliding block 22. The connecting seat 231 is provided with the lifting guide rail 233, which extends toward the lamp head fixing module 1. The lifting slider 234 is slidably connected to the lifting guide rail 233. The lifting cylinder 232 is disposed on the connecting seat 231. The telescopic shaft of the lifting cylinder 232 faces the lamp head fixing module 1 and is connected to the lifting slider 234. The clamping mechanism 24 is disposed on the lifting slider 234. The lifting cylinder 232 moves according to the vertical distance between the bubble 52 and the lamp head 51 calculated by the host computer of the vision detection system, thereby driving the lifting slider 234 to move along the lifting guide rail 233, and then driving the clamping mechanism 24 to move synchronously. The clamping mechanism 24 is preferably a finger cylinder, used to clamp the bubble 52.

[0026] Specifically, such as Figure 2 As shown, the dual-axis translation component 25 includes an X-axis translation guide rail 251, an X-axis translation slider 252, and a Y-axis translation guide rail 253. The X-axis translation guide rail 251 is disposed on the lower base 21, the X-axis translation slider 252 is slidably connected to the X-axis translation guide rail 251, the Y-axis translation guide rail 253 is disposed on the X-axis translation slider 252, and the sliding block 22 is slidably connected to the Y-axis translation guide rail 253. The X-axis translation slider 252 moves along the X-axis translation guide rail 251 to drive the lifting component 23 to translate along the X-axis, and the sliding block 22 moves along the Y-axis translation guide rail 253 to drive the lifting component 23 to translate along the Y-axis.

[0027] It is worth noting that, such as Figure 4 As shown, the lamp holder fixing module 1 includes an upper base 11, a pressing block 13, and a pressing cylinder 14. The upper base 11 has a fixing hole 12. The telescopic shaft of the pressing cylinder 14 extends downward and faces the fixing hole 12. The pressing block 13 is located at the end of the telescopic shaft of the pressing cylinder 14. After the pressing cylinder 14 is activated, its telescopic shaft drives the pressing block 13 to press down, thereby pressing the lamp holder 51 tightly against the fixing hole 12, which in turn cooperates with the upward force provided by the lifting assembly 23.

[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
