Description

Technical Field

[0001] This application relates to the field of adapter manufacturing technology, and in particular to a device that can avoid incomplete welding in laser welding of adapters. Background Technology

[0002] An adapter is a component used to connect, convert, or adapt different interfaces, parts, or systems. It is widely used in electronics, machinery, automobiles, industrial equipment, and other fields. Its function is to achieve compatibility between different devices or parts through standardized interfaces, simplifying the installation, maintenance, and upgrade process.

[0003] In the laser welding process of the adapter plate, most existing technologies use diffuse reflection photoelectric detection to detect whether the adapter plate has a top cover, and then laser weld the connecting plate and the top cover. However, due to the disadvantages of photoelectric technology, such as low precision, susceptibility to environmental influences, inability to detect the distance of the top cover, and inability to guarantee the consistency of the height of the top cover after placement, it can lead to incomplete welding and affect product performance. Therefore, it needs to be improved. Utility Model Content

[0004] In order to improve the problem of poor welds that easily occur during laser welding of adapter plates, which affects product quality, this application provides a device that can avoid poor welds during laser welding of adapter plates.

[0005] The device provided in this application that can avoid incomplete welding in laser welding of adapter plates adopts the following technical solution:

[0006] A device for avoiding incomplete welding of adapter plates in laser welding includes a worktable with two fixtures for supporting a top cover placed on its surface. A laser is mounted above the fixtures, and a laser displacement sensor for detecting the distance to the top cover is mounted on one side of the laser. An adjustment groove is formed on the surface of the worktable, located below the two fixtures, and an adjustment component for adjusting the top cover is mounted inside the adjustment groove.

[0007] By adopting the above technical solution, the laser displacement sensor has the advantages of higher accuracy and less susceptibility to environmental influences compared to diffuse reflection photoelectric detection. It can detect the height of the top cover before welding to prevent cold welding and thus improve the product yield. The adjustment component can adjust the position of the top cover when it is not placed accurately, thereby improving the placement accuracy of the top cover and the fixture, reducing the probability of cold welding and improving the welding quality.

[0008] Preferably, the adjustment assembly includes an adjustment screw, a rotating component, two adjustment blocks, and two adjustment plates. The adjustment blocks and adjustment plates correspond one-to-one. The adjustment screw is rotatably connected to the adjustment groove, and the length direction of the adjustment screw is consistent with the length direction of the adjustment groove. The adjustment screw includes threaded sections with opposite directions at both ends. The rotating component is disposed on the outer wall of the worktable, and the output shaft of the rotating component passes through the side wall of the worktable and is connected to the adjustment screw. Both adjustment blocks are sleeved on the peripheral wall of the adjustment screw, and the adjustment blocks abut against the inner wall of the adjustment groove. The adjustment plates are disposed on the top wall of the corresponding adjustment blocks.

[0009] By adopting the above technical solution, the rotating component starts and drives the adjusting screw to rotate. The two adjusting blocks are driven to move towards each other or away from each other by the threaded sections at both ends of the adjusting screw. When the two adjusting blocks are close to each other, they can abut against the side wall of the top cover through the adjusting plate, thereby moving the top cover to the center position to improve the welding accuracy of the top cover.

[0010] Preferably, the worktable surface is further provided with two driven grooves, the adjustment groove is located between the two driven grooves, the adjustment groove is parallel to the driven groove, a limit rod is provided in the driven groove, and a connecting groove is provided on the inner wall of both sides of the adjustment groove. The connecting groove is used to connect the driven groove and the adjustment groove. A driven block is slidably connected to the limit rod, and a connecting rod is provided on the side wall of the driven block. The connecting rod passes through the connecting groove and is connected to the adjustment block. A driven plate is provided on the surface of the driven block.

[0011] By adopting the above technical solution and setting the driven groove and driven block, the position of the fixture can be adjusted at the same time when the position of the top cover is adjusted, so as to achieve the alignment of the top cover and the fixture, thereby improving the subsequent welding accuracy and product quality.

[0012] Preferably, the driven plate includes a fixed block, a movable block, and an elastic element. The fixed block is connected to the surface of the driven block. The side of the fixed block facing the fixture has a relief groove for the movable block to be embedded in. The elastic element is disposed in the relief groove and abuts against the inner wall of the relief groove and the movable block.

[0013] By adopting the above technical solution, the driven plate is set into a structure that can provide cushioning, so that the moving block can rebound, thereby preventing the driven plate from excessively squeezing the fixture and causing damage to the fixture.

[0014] Preferably, the driven block has a plurality of fixing holes on its surface, the plurality of fixing holes being distributed along the length direction of the driven groove, the sidewall of the fixing block being provided with a connecting piece, and the connecting piece being provided with a fastener.

[0015] By adopting the above technical solution and setting several fixing holes and connecting pieces, the distance between the driven plate and the fixture can be adjusted so that the driven plate can be flexibly adjusted according to the actual situation, preventing the driven plate from excessively squeezing the fixture and causing damage to the fixture.

[0016] Preferably, the inner walls of the adjustment groove in both length directions are provided with alignment scales, and the alignment scales abut against the sides of the two fixtures that are close to each other.

[0017] By adopting the above technical solution, setting an alignment ruler can ensure that the two fixtures are centered in the left-right direction perpendicular to the adjustment groove, thereby improving the accuracy and quality of subsequent laser welding.

[0018] Preferably, the surface of the fixture is provided with scale lines for aligning the top cover.

[0019] By adopting the above technical solution, setting scale lines on the surface of the fixture can effectively maintain the alignment of the top cover and the fixture in the left and right directions, thereby ensuring the quality of subsequent laser welding.

[0020] Preferably, an adjustment ring is rotatably connected to the laser, and the laser displacement sensor is disposed on the bottom wall of the adjustment ring.

[0021] By adopting the above technical solution, the laser displacement sensor can be driven to rotate, thereby enabling all-round detection of the top cover distance, further reducing the probability of poor soldering of the top cover and improving product quality.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Compared with diffuse reflection photoelectric detection, laser displacement sensors have the advantages of higher accuracy and less susceptibility to environmental influences. They can detect the height of the top cover before welding to prevent cold solder joints, thereby improving product yield. The adjustment component can adjust the position of the top cover when it is not placed accurately, thereby improving the placement accuracy of the top cover and the fixture, reducing the probability of cold solder joints, and improving welding quality.

[0024] 2. The rotating component starts, driving the adjusting screw to rotate. The two adjusting blocks are moved towards each other or away from each other by the opposite threaded sections at both ends of the adjusting screw. When the two adjusting blocks are close to each other, they can abut against the side wall of the top cover through the adjusting plate, thereby moving the top cover to the center position to improve the welding accuracy of the top cover.
