Description

Technical Field

[0001] This utility model relates to the field of welding visual inspection technology, specifically a visual inspection device for welding positioning. Background Technology

[0002] In everyday life, welding visual inspection is a method that uses machine vision technology to inspect the welding process and results. It captures images of the welding process using high-resolution cameras or sensors, and then uses image processing algorithms to analyze and process these images, thereby enabling the detection and evaluation of welding quality.

[0003] Currently, after the welding work is completed, the welding quality of the welded parts needs to be inspected manually. However, manual inspection not only has a large error rate, but also requires personnel to frequently move their positions and perspectives when there are too many welded parts, resulting in very low inspection efficiency. As a result, the yield of welded parts cannot be guaranteed. Utility Model Content

[0004] The purpose of this invention is to provide a visual inspection device for welding positioning, in order to solve the problem mentioned in the background art that, after the welding work is completed, the welding quality of the welded parts needs to be inspected manually. However, manual inspection not only has a large error rate, but also requires personnel to frequently move their positions and viewing angles when there are too many welded parts, resulting in very low inspection efficiency. Thus, it is impossible to guarantee the yield of welded parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a visual inspection device for welding positioning, comprising a processing table, with second limiting grooves on both sides of the processing table, and second limiting blocks slidably connected to the inner walls of the two second limiting grooves. A fourth cylinder is fixedly connected to the top of the second limiting blocks, and a first fixing slot block is fixedly connected to the output end of the fourth cylinder. A second motor is fixedly connected inside the first fixing slot block, and a semi-internal gear ring is fixedly connected to the output end of the second motor. A limiting circular groove is formed inside the semi-internal gear ring, and a limiting slot block is slidably connected to the inner wall of the limiting circular groove. A third motor is fixedly connected inside the limiting slot block, and a gear is fixedly connected to the output end of the third motor. The gear meshes with the semi-internal gear ring. A second fixing slot block is fixedly connected to one side of the limiting slot block, and a fourth motor is fixedly connected inside the second fixing slot block. An electric telescopic rod is fixedly connected to the output end of the fourth motor, and an inspection camera is fixedly connected to the telescopic end of the electric telescopic rod.

[0006] As a preferred embodiment of this utility model: a first cylinder is fixedly connected to both sides of the processing table, a first limiting block is fixedly connected to the output ends of the two first cylinders, a second cylinder is fixedly connected to the top of the first limiting block, a first clamping block is fixedly connected to the output end of the second cylinder, a third cylinder is fixedly connected to the bottom of the first clamping block, and a second clamping block is fixedly connected to the output end of the third cylinder.

[0007] As a preferred embodiment of this utility model: the processing table has a first limiting groove inside that cooperates with the first limiting block.

[0008] As a preferred embodiment of this utility model: a first motor is fixedly connected to the inner wall of the second limiting slide groove, and a first reciprocating screw is fixedly connected to the output end of the first motor, and the first reciprocating screw is threadedly connected to the second limiting block.

[0009] As a preferred embodiment of this utility model: a control panel is fixedly connected to one side of the processing table, and the control panel is electrically connected to the first cylinder, the second cylinder, the third cylinder, the first motor, the fourth cylinder, the second motor, the third motor, the fourth motor, the electric telescopic rod, and the detection camera.

[0010] The beneficial effects of this utility model are as follows: This utility model has a novel structure, is simple to operate, and is easy to learn. It is not only compact in structure but also more practical. Compared with traditional devices, this utility model, by setting a fourth cylinder, a second motor, a semi-internal gear ring, a limiting circular groove, a limiting groove block, a third motor, a gear, a second fixed groove block, a fourth motor, an electric telescopic rod, and a detection camera, can clamp welds with circular or square cross-sections in two semi-internal gear rings. For circular welds, the detection camera can rotate along the semi-internal gear ring, thus taking pictures of the circular welds in a full circle. For welds with square cross-sections, the fourth motor can adjust the detection camera to a position perpendicular to the square, and then the detection camera can be moved linearly to complete the picture inspection of the square cross-section. In this way, manual visual inspection is not required, which not only reduces the workload but also improves the inspection efficiency and ensures the yield of welded products.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 5 This utility model provides a technical solution: a visual inspection device for welding positioning, including a processing table 1, with second limiting grooves 9 on both sides of the processing table 1, and second limiting blocks 12 slidably connected to the inner walls of the two second limiting grooves 9. A fourth cylinder 13 is fixedly connected to the top of the second limiting blocks 12, and a first fixing slot block 14 is fixedly connected to the output end of the fourth cylinder 13. A second motor 15 is fixedly connected inside the first fixing slot block 14, and a semi-internal gear ring 16 is fixedly connected to the output end of the second motor 15. A limiting groove 17 is provided in the part, and a limiting groove block 18 is slidably connected to the inner wall of the limiting groove 17. A third motor 19 is fixedly connected inside the limiting groove block 18. A gear 20 is fixedly connected to the output end of the third motor 19. The gear 20 meshes with the semi-internal gear ring 16. A second fixing groove block 21 is fixedly connected to one side of the limiting groove block 18. A fourth motor 22 is fixedly connected inside the second fixing groove block 21. An electric telescopic rod 23 is fixedly connected to the output end of the fourth motor 22. A detection camera 24 is fixedly connected to the telescopic end of the electric telescopic rod 23.

[0019] By setting up a fourth cylinder 13, a second motor 15, a semi-internal gear ring 16, a limiting circular groove 17, a limiting groove block 18, a third motor 19, a gear 20, a second fixing groove block 21, a fourth motor 22, an electric telescopic rod 23, and an inspection camera 24, the welded parts with circular or square cross-sections can be clamped in two semi-internal gear rings 16. For circular welded parts, the inspection camera 24 can rotate along the semi-internal gear ring 16, thus taking pictures and inspecting the circular welded parts in a full circle. For welded parts with square cross-sections, the fourth motor 22 can adjust the inspection camera 24 to a position perpendicular to the square, and then the inspection camera 24 can be moved linearly to complete the picture inspection of the square cross-section. In this way, manual visual inspection is not required, which not only reduces the workload but also improves the inspection efficiency and ensures the yield of welded parts.

[0020] The processing table 1 is fixedly connected to two sides with first cylinders 2. First limiting blocks 4 are fixedly connected to the output ends of the two first cylinders 2. Second cylinders 5 are fixedly connected to the top of the first limiting blocks 4. First clamping blocks 6 are fixedly connected to the output ends of the second cylinders 5. Third cylinders 7 are fixedly connected to the bottom of the first clamping blocks 6. Second clamping blocks 8 are fixedly connected to the output ends of the third cylinders 7. This allows for easy clamping of the welded parts through the cooperation of the second cylinders 5 and 7. Furthermore, the welded parts can be adjusted to the required height using the second cylinders 5 according to inspection needs. The processing table 1 has a first limiting groove 3 inside that mates with the first limiting blocks 4, allowing for the insertion of the first limiting block 3 into the first limiting block 4. The position block 4 and the first limiting groove 3 cooperate to provide a guiding and limiting function; the inner wall of the second limiting slide groove 9 is fixedly connected to the first motor 10, and the output end of the first motor 10 is fixedly connected to the first reciprocating lead screw 11. The first reciprocating lead screw 11 is threadedly connected to the second limiting block 12, which can facilitate the movement of the detection position; a control panel is fixedly connected to one side of the processing table 1. The control panel is electrically connected to the first cylinder 2, the second cylinder 5, the third cylinder 7, the first motor 10, the fourth cylinder 13, the second motor 15, the third motor 19, the fourth motor 22, the electric telescopic rod 23, and the detection camera 24, and can control the operation of this device through the control panel.

[0021] Specifically, a circular or square weldment is placed on the processing table 1. The control panel controls the first cylinder 2 to push the first limiting block 4 to slide within the first limiting groove 3, thus allowing for adjustment according to the length of the weldment. The weldment is then placed on the first clamping block 6. Next, the third cylinder 7 is controlled to move the second clamping block 8 downwards, allowing the first clamping block 6 and the second clamping block 8 to cooperate in clamping and fixing the weldment. The inner sides of the first clamping block 6 and the second clamping block 8 can be used to clamp weldments with a circular cross-section, while the flat surfaces are horizontally cut to clamp square weldments. Figure 5As shown, after clamping and fixing are completed, the two second motors 15 are controlled to rotate, causing the two semi-internal gear rings 16 to rotate and approach each other, thus merging the two semi-internal gear rings 16 into one internal gear ring. When inspecting the welded part with a circular cross-section, the third motor 19 is controlled to rotate the gear 20, causing the gear 20 to move along the internal teeth of the semi-internal gear ring 16. When the limiting slot block 18 moves, it slides within the semi-internal gear ring 16. Based on the distance between the inspection camera 24 and the welded part, the electric telescopic rod 23 is controlled to push the inspection camera 24 to adjust, thereby ensuring the effect of the photographic inspection. Furthermore, the third motor 19... The inspection camera 24 can move in a circle to take pictures of the welded parts. The first motor 10 rotates the first reciprocating screw 11, causing the second limiting block 12 to slide within the second limiting groove 9. This allows the inspection camera 24 to move linearly to take pictures. When taking pictures of welded parts with a square cross-section, the fourth motor 22 can rotate the electric telescopic rod 23, thereby adjusting the inspection camera 24 to a position perpendicular to the welded parts with a square cross-section. Then, the first motor 10 can move the inspection camera 24 to complete the picture inspection of the welded parts with a square cross-section.
