[0022] 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.

[0023] See also Figures 1-5 The utility model provides a technical solution: a welding spot visual inspection device, including a frame 1, on which a control electric box 6, a light source 7, an indicator light 8 and an emergency stop switch 9 are respectively arranged, and a camera 2 is also arranged at the upper end of the frame 1, and a placement table 3 is arranged directly below the camera 2. The placement table 3 is mainly used to place samples to be tested that need to inspect welding spots. By placing the samples to be tested on the placement table 3, and then using the camera 2 to take pictures of the samples to be tested, and comparing and identifying the pictures taken with pictures of standard samples pre-stored in the system, it is possible to quickly check whether there are missing welding spots on the samples to be tested and whether there are deviations in the positions of the welding spots. Compared with traditional manual inspections, the accuracy of the inspection results can be greatly improved.

[0024] A fixing device 4 for clamping and fixing the sample to be tested is also provided on the placement table 3. The fixing device 4 includes a support plate 40 fixedly installed on the placement table 3 and a clamping cylinder 41 fixedly installed on the support plate 40. The fixing device 4 also includes a clamping claw 42 rotatably connected to the support plate 40, and the clamping claw 42 is transmission-connected to the clamping cylinder 41. A support frame 30 fixedly installed therewith is also provided on the placement table 3. When no sample to be tested is placed, the lower end surface of the clamping claw 42 and the upper end surface of the support frame 30 are clamped correspondingly to each other when the clamping claw 42 is not opened. When the sample to be tested needs to be placed on the placement table 3 and fixed, the clamping claw 42 is first driven to be lifted by the clamping cylinder 41, and then the sample to be tested is placed on the support frame 30 located on the placement table 3, and then the clamping claw 42 is driven to be pressed downward by the clamping cylinder 41 to close between the support frame 30, so as to clamp and fix the sample to be tested located on the support frame 30.

[0025] On the frame 1, there is also a flipping device 5 for driving the placement table 3 to flip. By providing the flipping device 5, the placement table 3 can be driven to flip, so that the other side of the sample to be tested can also be inspected. The flipping device 5 further includes bearings 50 rotatably connected to the frame 1. The bearings 50 are respectively located on both sides of the frame 1. At one end where the two bearings 50 correspond to each other, there is a rotatable plate 51 fixedly connected. The rotatable plate 51 is fixedly connected to the placement table 3. At the other end of one of the bearings 50, there is a gear 52 fixedly connected thereto. The flipping device 5 further includes a servo motor 53 fixedly installed on the frame 1. The driving end of the servo motor 53 is connected to the gear 52 through a chain drive. Therefore, after the camera 2 takes a photo and makes a comparison inspection on one side of the sample to be tested located on the placement table 3, the servo motor 53 can be driven to drive the bearing 50 to drive the rotatable plate 51 to rotate, thereby driving the placement table 3 to flip. Moreover, there are several observation holes 31 on the placement table 3, and the observation area of the observation holes 31 is large enough. Therefore, after the placement table 3 flips, the camera 2 can be used to take a photo and identify and inspect the other side of the sample to be tested.

[0026] There is also an induction block on the rotatable plate 51, and the frame 1 is provided with a fixedly installed inductor 55. The inductor 55 is arranged corresponding to the induction block 54, and the inductor 55 is signal-connected to the servo motor 53. By providing the induction block 54 on the rotatable plate 51, when the servo motor 53 drives the rotatable plate 51 to rotate and drives the placement table 3 to flip, if the placement table 3 flips in place, the inductor 55 will sense with the induction block 54, so that the inductor 55 will send a signal to the servo motor 53, thereby causing the servo motor 53 to stop driving, and then completing the flipping of the sample to be tested on the placement table 3.

[0027] The working principle or beneficial effect of the present utility model: When it is necessary to check whether the solder joints on the sample to be tested are missing or whether there is a deviation in the solder joint position, first place the sample to be tested on the placement table 3 and clamp it with the fixing device 4, then use the camera 2 to take a photo of it, and then compare the taken photo with the standard sample photo pre-stored in the system to quickly obtain the inspection result. When one side of the sample to be tested is inspected, then use the flipping device 5 to drive the placement table 3 to flip, so as to facilitate the inspection of the other side of the sample to be tested. The entire inspection process of the solder joints does not require manual participation, which can greatly reduce the labor cost, and while the inspection efficiency is greatly improved, the inspection accuracy can also be ensured.

[0028] Finally, it should be noted that the above are only preferred examples of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
