Description

Technical Field

[0001] The utility model relates to the technical field of mold product detection, in particular to a six-axis robot visual detection device. Background Art

[0002] After a product is manufactured through a mold, it is often inspected. Minor deviations or defects may occur during the mold manufacturing process, which can directly affect the final product quality. Inspection can promptly identify these issues, ensuring that the product's dimensions, appearance, and functionality meet design requirements, thereby improving overall product quality.

[0003] Current product inspection on molds relies heavily on manual labor, significantly slowing down inspections and introducing the risk of human error. Limited by the operator's energy, experience, and judgment, manual inspections often fall short of large-scale, high-precision product inspections, making it difficult to ensure consistency and accuracy. Furthermore, manual inspections are inefficient, and as the number of products increases, inspection cycles continue to lengthen, making it difficult to meet the demands of modern production for high efficiency and rapid response. Therefore, we propose a six-axis robotic vision inspection system. Utility Model Content

[0004] The purpose of the present utility model is to provide a six-axis robot visual inspection device to solve the problem raised in the above background technology that the current product inspection on the mold is overly dependent on manual operation. This situation not only significantly slows down the inspection speed, but also inevitably introduces the risk of human error. Manual inspection is limited by the operator's energy, experience and judgment. When faced with large-scale, high-precision product inspection tasks, it often seems powerless and difficult to ensure the consistency and accuracy of the inspection. In addition, manual inspection also faces the problem of low efficiency. As the number of products increases, the inspection cycle continues to extend, making it difficult to meet the needs of modern production for efficient and rapid response.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a six-axis robot visual inspection device, comprising a base, a stud is provided in the center of the base, a detection seat is provided on one side of the upper end of the base, movable sleeves are threadedly connected to the two side positions of the surface of the stud, a rotating rod is movably installed on one side of the top of the base, an adjustment handle is fixedly installed on the top of the rotating rod, grooves are provided at the front and rear ends of the top of one side of the base, a spring is fixedly connected to one side of the groove, one end of the spring is fixedly connected to a limiting rod, one end of the limiting rod passes through the outside of the groove and is fixedly connected to a rubber head, a six-axis robot body is fixedly installed on one side of the top of the base, and a visual camera is provided on one side of the six-axis robot body.

[0006] Compared with the prior art, the beneficial effects of the present invention are:

[0007] The six-axis robot visual inspection device realizes precise displacement control of the inspection seat through the design of the stud, inspection seat, movable sleeve, rotating rod, adjustment handle, spring, limit rod and rubber head. The interaction between the thread on the surface of the stud and the movable sleeve realizes precise displacement control of the inspection seat. When the adjustment handle is rotated, the rotating rod drives the stud to rotate through the meshing action of the bevel gear, and then drives the movable sleeve to move along the axial direction of the stud, thereby driving the inspection seat to move closer to or away from the limit rod. The rubber head at one end of the limit rod contacts the mold to achieve stable positioning of the mold, avoid displacement of the mold during the inspection process, and ensure the accuracy and stability of visual inspection. The limit rod is connected to the base through a spring. The elastic buffering effect of the spring can effectively absorb the impact force when the mold contacts the limit rod, preventing the mold and product from being damaged due to sudden contact. At the same time, the elastic force of the spring ensures that the rubber head can fit closely to the mold surface, achieving stable positioning, avoiding displacement of the mold during the inspection process, and ensuring the accuracy and stability of visual inspection. The existence of the spring also allows a certain amount of adjustment space, so that molds of different sizes can obtain a suitable fixing effect, realizing fast, accurate, stable positioning and efficient visual inspection of molds and their products, which has significant technological progress and practical value.

A rotating rod 6 is movably installed on one side of the top of the base 1, and an adjusting handle 8 is fixedly installed on the top of the rotating rod 6. Grooves 9 are provided at the front and rear ends of the top of one side of the base 1, and a spring 10 is fixedly connected to one side of the groove 9. One end of the spring 10 is fixedly connected to a limiting rod 20, and one end of the limiting rod 20 passes through the outside of the groove 9 and is fixedly connected to a rubber head 21. A six-axis robot body 13 is fixedly installed on one side of the top of the base 1, and a visual camera 17 is provided on one side of the six-axis robot body 13.

[0015] The two ends of the stud 2 are movably connected to the bearings fixedly installed in the center of both sides of the base 1. A guide rod 22 is provided near the bottom of the base 1. The two ends of the guide rod 22 respectively penetrate the outside of the two movable sleeves 4 and are fixedly connected to the two sides of the bottom of the base 1, allowing the stud 2 to be used as a driving component to drive other components to perform linear motion through rotation, such as movement through the interaction between the thread and the movable sleeve 4, thereby adjusting the position of the mold or workpiece. At the same time, the guide rod 22 can enable the movable sleeve 4 to maintain linear motion when moving up and down under the drive of the stud 2, avoiding deviation or shaking, and ensuring the accuracy and stability of the operation.

[0016] Slide grooves 11 are provided at the top and bottom of the groove 9, and sliders 12 are fixedly connected to one side of the top and bottom of the limit rod 20. The top and bottom of the slider 12 extend into the two slide grooves 11 respectively and are slidably connected to the inner walls of the slide grooves 11, limiting the movement trajectory of the limit rod 20 in the groove 9 so that it can only move along a predetermined path. This design enhances the stability and reliability of the structure and prevents the limit rod 20 from deflecting or dislocating during movement.

[0017] A movable groove is provided on one side of the top of the base 1, and the centers of the tops of the two movable sleeves 4 are fixedly connected with connecting blocks 5. The upper ends of the two connecting blocks 5 pass through the outside of the movable sleeves 4 and are fixedly connected to the bottom of the detection seat 3. The two movable sleeves 4 can respectively drive the two connecting blocks 5 along the movable groove to drive the top detection seat 3 to move.

[0018] The lower end of the rotating rod 6 passes through the interior of the base 1, and bevel gears 7 are fixedly installed on one side of the surface of the stud 2 and the bottom of the rotating rod 6. The two bevel gears 7 are meshed and connected. When the rotating rod 6 is rotated, the bevel gear 7 at its bottom will drive the bevel gear 7 on the stud 2 to rotate, thereby rotating the stud 2, realizing the conversion from rotational motion to linear motion.

[0019] One end of the six-axis robot body 13 is fixedly connected to a connector 14, one side of the connector 14 is fixedly connected to a pillar 15, the upper end of the surface of the pillar 15 is fixedly connected to a connecting plate 16, one side of the connecting plate 16 is fixedly installed with a visual camera 17, the bottom position of the surface of the pillar 15 is fixedly connected to a lens fixing plate 18, one end of the lens fixing plate 18 is fixedly connected to the bottom position of the surface of the visual camera 17, and a light source ring 19 is fixedly installed at the bottom of one side of the pillar 15, forming a complete visual inspection system. The visual camera 17 is used to capture image information of the mold or workpiece, and the light source ring 19 provides stable lighting conditions to ensure image quality. This design enables the robot to use visual feedback for precise positioning and detection, thereby improving the accuracy and efficiency of automated production.

[0020] The detection seat 3 is set as an L-shaped structure. A mold is set at the upper end of the detection seat 3. The outer wall of the mold contacts the surface of the detection seat 3. One side of the rubber head 21 contacts the surface of the mold, which is used to limit the two sides of the mold to avoid displacement of the product on the mold during the detection process.

[0021] The bottom of the base 1 is fixedly connected to a mounting plate, and the top of the mounting plate is provided with a mounting hole, which provides an interface for fixing the entire device to a production line or a workbench.

[0022] Working principle: First, place the mold to be tested and the product on the mold on the upper end of the detection seat 3, ensure that the outer wall of the mold is in full contact with the surface of the detection seat 3 to initially stabilize the mold position, then turn the adjustment handle 8 to rotate the rotating rod 6. Since the bottom of the rotating rod 6 is engaged with the bevel gear 7 on the stud 2, the rotation of the rotating rod 6 will be converted into the rotation of the stud 2. The rotation of the stud 2 interacts with the movable sleeve 4 through the thread on its surface, driving the movable sleeve 4 to move along the axial direction of the stud 2. Since the top of the movable sleeve 4 is fixedly connected to the connecting block 5, and the connecting block 5 is fixedly connected to the bottom of the detection seat 3, the movement of the movable sleeve 4 will drive the detection seat 3 and the mold on it to move together. As the detection seat 3 moves, the fixed The rubber head 21 on the limiting rod 20 on the base 1 gradually approaches the mold. When the rubber head 21 contacts the mold surface, due to the elastic buffering effect of the spring 10, the rubber head 21 can gently fit the mold surface to avoid impact on the mold and the product. After the rubber head 21 is tightly fitted to the mold surface, the mold is firmly positioned on the detection seat 3. At this time, the mold and its product will not be displaced during the subsequent visual inspection process, ensuring the accuracy and stability of the inspection. After the mold and the product are firmly fixed, the visual inspection system on the six-axis robot body 13 is started, and the visual camera 17 starts to capture image information of the mold or workpiece under the stable lighting conditions provided by the light source ring 19, and then performs inspection operations on the product.

[0023] In summary: the six-axis robot visual inspection device, through the design of the stud 2, the inspection seat 3, the movable sleeve 4, the rotating rod 6, the adjusting handle 8, the spring 10, the limit rod 20 and the rubber head 21, the stud 2 realizes the precise displacement control of the inspection seat 3 through the interaction between the thread on its surface and the movable sleeve 4, when the adjusting handle 8 is rotated, the rotating rod 6 drives the stud 2 to rotate through the meshing action of the bevel gear 7, and then drives the movable sleeve 4 to move along the axial direction of the stud 2, thereby driving the inspection seat 3 to move closer to or away from the limit rod 20, and the rubber head 21 at one end of the limit rod 20 contacts the mold to achieve stable positioning of the mold, avoid displacement of the mold during the inspection process, and ensure the accuracy of visual inspection. Accuracy and stability, at the same time, the limit rod 20 is connected to the base 1 through the spring 10, and the elastic buffering effect of the spring 10 can effectively absorb the impact force when the mold contacts the limit rod 20, preventing the mold and the product from being damaged due to sudden contact. At the same time, the elastic force of the spring 10 ensures that the rubber head 21 can fit closely to the mold surface to achieve stable positioning, avoid the displacement of the mold during the inspection process, and ensure the accuracy and stability of visual inspection. The existence of the spring 10 also allows a certain amount of adjustment space, so that molds of different sizes can get a suitable fixing effect, realizing fast, accurate, stable positioning and efficient visual inspection of the mold and its products, which has significant technological progress and practical value.
