Description

Technical Field

[0001] This utility model relates to the field of product visual inspection technology, specifically a product solder joint visual inspection device. Background Technology

[0002] Visual inspection is the use of machines to replace human eyes for measurement and judgment. Visual inspection refers to the process of using machine vision products (i.e., image acquisition devices, which are divided into CMOS and CCD) to convert the captured target into image signals, which are then transmitted to a dedicated image processing system. Based on pixel distribution and information such as brightness and color, the signals are converted into digital signals. The image system performs various operations on these signals to extract the features of the target, and then controls the operation of the equipment on site based on the judgment results.

[0003] Currently, after the welding work is completed, visual inspection equipment is needed to visually inspect the weld points of the product to ensure the welding quality. However, the existing visual inspection equipment can only inspect one side of the product, and the inspection range is small. It requires the staff to manually adjust the product inspection position, resulting in low inspection efficiency. Improvement is needed. Utility Model Content

[0024] The rotating assembly 11 includes a drive box 112 fixed to the top of the Y-axis drive assembly 6. A rotary motor 111 is mounted on the top of the drive box 112. A gear set (not shown) is installed inside the drive box 112. One side of the fixed seat 113 is connected to the drive box 112 via a rotating shaft. One end of the shaft of the fixed seat 113 is connected to the shaft of the rotary motor 111. In this structure, the rotary motor 111 drives the fixed seat 113 to rotate via the shaft through gear meshing (not shown). The fixed seat 113 is rotatably connected to one side of the drive box 112. A base plate 115 is fixedly connected to one side of the fixed seat 113. The length of the base plate 115 is greater than the length of the clamping plate 114. The clamping plate 114 and the base plate 115 form a parallel structure. The clamping plate 114 can clamp the product on top of the base plate 115, thereby improving the stability of the product when adjusting the angle. An adjustment motor 118 is installed at the bottom of the base plate 115. A groove is opened on the top of the base plate 115, and a turntable 117 is rotatably connected inside the groove. The shaft at the bottom of turntable 117 is connected to the shaft of adjusting motor 118 via a coupling, and turntable 117 and base plate 115 form a rotatable connection. In this structure, adjusting motor 118 can drive turntable 117 to rotate, thereby horizontally adjusting the angle of the product on top of base plate 115 and expanding the product inspection range. A clamping electric cylinder 116 is installed on the bottom side of base plate 115, and one end of clamping electric cylinder 116 is connected to clamping plate 114. The X-axis drive assembly 9, Z-axis drive assembly 8 and Y-axis drive assembly 6 of this device can all be linear motors. A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. The linear motor mainly drives the object to be moved by the movement of the moving slider. The moving slider of X-axis drive assembly 9 is connected to the base of Z-axis drive assembly 8, the moving slider of Z-axis drive assembly 8 is connected to the bracket of the area array camera 7, and the moving slider of Y-axis drive assembly 6 is fixedly connected to drive box 112.

[0025] Working principle: When using this product's weld joint visual inspection device, first place the product to be inspected on top of the base plate 115, simultaneously positioning the product on top of the turntable 117. Then, the clamping cylinder 116 drives the clamping plate 114 to approach and clamp the product. After the product is fixed, the Y-axis drive assembly 6 drives the components on the drive box 112 to move towards the area scan camera 7, positioning the product at the bottom of the area scan camera 7 for inspection. If the inspection angle of the product needs to be adjusted during the inspection process, the rotary motor 111 drives the fixed base 113 to rotate. When rotating, the base plate 115, clamping plate 114, and product rotate synchronously. The horizontal angle of the product can also be adjusted. When adjusting, the clamping plate 114 returns to its original position when the base plate 115 is in a horizontal state. The adjusting motor 118 drives the turntable 117 to rotate, and the turntable 117 drives the product to adjust its horizontal angle. When the product is at a suitable angle, the clamping plate 114 clamps the product again and then performs the inspection. During the inspection, the area scan camera 7 reads the code and uploads it to the MES. Then the camera takes pictures of the product's solder joints, checks the size of the solder joints and detects any missing solder joints. After completion, the product is manually removed.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
