Description

Technical Field

[0001] This utility model relates to the technical field of die casting inspection equipment, and in particular to a die casting appearance inspection device. Background Technology

[0002] In the die-casting production process, visual inspection is a crucial step in ensuring product quality. Currently, the common inspection method relies on manual visual inspection. This method is not only labor-intensive and inefficient, but also prone to missed inspections or misjudgments due to factors such as the subjective fatigue of the inspectors, making it difficult to guarantee the consistency of product quality.

[0003] To overcome the drawbacks of manual inspection, automated vision inspection equipment has been gradually adopted. These devices typically use industrial cameras to capture images of workpieces and perform comparative analysis. However, many existing automated inspection devices have limitations: for example, some devices can only photograph workpieces from a single angle or fixed position, making it difficult to fully inspect complex die-cast parts such as the bottom and sidewalls, which are often blind spots; other devices, while equipped with multiple cameras, often require numerous cameras to surround the workpiece from different angles on the conveyor line due to the workpiece's static or horizontal movement, resulting in complex and costly systems that may still suffer from incomplete coverage. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a die casting appearance inspection device to solve the problems of blind spots and high inspection costs of existing die casting appearance inspection equipment.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A die-casting part appearance inspection device includes a work frame with two inspection frames arranged opposite each other on the work frame. Each of the two inspection frames is equipped with a visual inspection component that can be raised and lowered. A plurality of rollers for transporting die-casting parts are arranged between the two inspection frames. A drive plate for lifting and rotating the passing die-casting parts is provided on the work frame and located between the two inspection frames.

[0007] The present invention is further configured such that: the detection component includes a vision probe and a supplementary light ring; a screw is vertically rotatably mounted on the detection frame; an installation sleeve is threaded onto the screw; the side wall of the installation sleeve slides against the side wall of the detection frame; the vision probe is located on the side of the installation sleeve near the roller; the supplementary light ring is fixed on the side wall of the vision probe; and a driving component for driving the screw to rotate is provided on the work frame.

[0008] The present invention is further configured such that: a positioning rod is horizontally slidably inserted through the mounting sleeve; one end of the vision probe is fixedly connected to the positioning rod; the positioning rod has a plurality of positioning holes; the mounting sleeve has a countersunk hole corresponding to and communicating with one of the positioning holes; a positioning pin with a top cap is inserted into the countersunk hole; the positioning pin is inserted into one of the positioning holes; a spring is also provided in the countersunk hole; the spring is sleeved on the positioning pin and fixedly connected to the top cap of the positioning pin and the countersunk plate of the countersunk hole respectively.

[0009] The present invention is further configured such that: the driving component includes a first motor, two pulleys and a belt, the first motor is fixed on the working frame, the two pulleys are respectively fixedly sleeved on the screw and the output end of the first motor, and the belt is sleeved between the two pulleys.

[0010] The present invention is further configured such that: a plurality of support rollers parallel to the axial direction of the roller are rotatably provided on the drive plate; a second motor is also provided on the work frame; a vertically arranged spline shaft is fixed on the output end of the second motor; a spline sleeve is fixed at the center of the drive plate shaft; and the spline sleeve is sleeved on the spline shaft.

[0011] The present invention is further configured such that: the working frame is provided with a plurality of vertically telescopic hydraulic cylinders, and each of the telescopic ends of the plurality of hydraulic cylinders is provided with rotatable balls; the drive plate is provided with an annular groove on the side away from the support roller with the spline sleeve as the axis, and the plurality of balls are evenly distributed in the groove.

[0012] The present invention is further configured such that an anti-slip layer is fitted on each of the support rollers.

[0013] Compared to the beneficial effects achieved by existing technologies:

[0014] By symmetrically arranging two inspection frames with liftable vision inspection components on the workbench, and placing a roller conveyor mechanism between them, efficient multi-angle and multi-directional vision inspection of die-cast parts can be achieved. A specially designed drive plate can lift and rotate the die-cast part as it passes by, ensuring that all surfaces are fully exposed within the vision inspection range, effectively avoiding blind spots and significantly improving the detection rate and consistency of appearance defects.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example:

[0022] Reference Figure 1 This application relates to a die-casting part appearance inspection device, including a work frame 1, on which two inspection frames 2 are arranged opposite each other. Visual inspection components are respectively mounted on the two inspection frames 2 in a lifting and lowering manner. Figure 2 As shown, the detection assembly includes a vision probe 5 and a supplementary lighting ring 6. A screw 7 is vertically rotatable on the detection frame 2, and a mounting sleeve 8 is threaded onto the screw 7. The side wall of the mounting sleeve 8 slides against the side wall of the detection frame 2. The vision probe 5 is located on the side of the mounting sleeve 8 near the roller. The supplementary lighting ring 6 is fixed to the side wall of the vision probe 5. The work frame 1 is equipped with a driving component for rotating the screw 7. The vision probe 5 can effectively visually inspect the shape of the die-cast part. Each vision probe 5 is wired to an external display and control device. The supplementary lighting ring 6 can effectively supplement the light to the area detected by the vision probe 5, improving the accuracy of the inspection. Figure 3 As shown, the driving component includes a first motor 14, two pulleys 15, and a belt 16. The first motor 14 is fixed on the work frame 1. The two pulleys 15 are respectively fixedly sleeved on the screw 7 and the output end of the first motor 14. The belt 16 is sleeved between the two pulleys 15. This effectively controls the rotation of the two screws 7 through the first motor 14 and the connected pulleys 15 and belt 16, and drives the mounting sleeve 8 and the vision probe 5 mounted on the mounting sleeve 8 to move up and down, which is suitable for more comprehensive inspection of die-cast parts.

[0023] like Figure 2As shown, a positioning rod 9 is horizontally slidably inserted through the mounting sleeve 8. One end of the vision probe 5 is fixedly connected to the positioning rod 9. The positioning rod 9 has several positioning holes 10. The mounting sleeve 8 has a countersunk hole 11 corresponding to one of the positioning holes 10. A positioning pin 12 with a top cap passes through the countersunk hole 11. The positioning pin 12 is inserted into one of the positioning holes 10. A spring 13 is also provided inside the countersunk hole 11. The spring 13 is sleeved on the positioning pin 12 and fixedly connected to the top cap of the positioning pin 12 and the countersunk hole 11. By sliding the positioning rod 9 on the mounting sleeve 8, the distance between the vision probe 5 and the die-cast part can be further adjusted, improving the inspection of die-cast parts of different sizes.

[0024] like Figure 1 As shown, several rollers 3 for transporting die-cast parts are provided between the two inspection frames 2, and a drive plate 4 for lifting and rotating the passing die-cast parts is provided on the work frame 1 and located between the two inspection frames 2. Figure 1 and Figure 2 As shown, the drive plate 4 is rotatably equipped with several support rollers 17 parallel to the axis of the roller 3, and each of the support rollers 17 is fitted with a rubber anti-slip layer 24. The work frame 1 is also equipped with a second motor 18, and a vertically arranged spline shaft 19 is fixed to the output end of the second motor 18. A spline sleeve 20 is fixed at the axis of the drive plate 4, and the spline sleeve 20 is fitted onto the spline shaft 19. The work frame 1 is equipped with several vertically telescopic hydraulic cylinders 21, and each of the telescopic ends of the hydraulic cylinders 21 is rotatably equipped with a ball 22. The drive plate 4 has an annular groove 23 on the side away from the support rollers 17 with the spline sleeve 20 as the axis, and the balls 22 are evenly distributed in the groove 23. The second motor 18 effectively drives the spline shaft 19 to rotate, which in turn drives the spline sleeve 20 to rotate the drive plate 4 and the die-cast part above it, enabling the vision probe 5 to inspect the die-cast part from all directions. The roller ball 22 on the hydraulic cylinder 21 engages with the roller groove 23 at the bottom of the drive plate 4, allowing the drive plate 4 to be adjusted in height while rotating, thus expanding the inspection range. When the first motor 14 and the second motor 18 are driven, those skilled in the art can reasonably connect a reducer or other adapter to their drive points. Both the first motor 14 and the second motor 18 can control the number of rotations and the angle of rotation, and the maximum rotation angle of the drive plate 4 should not exceed 180°.

[0025] Working principle:

[0026] During operation, the die-cast parts are conveyed by several rollers 3 to a predetermined station between two inspection frames 2. Subsequently, several hydraulic cylinders 21 on the work frame 1 are activated, and their telescopic ends push the drive plate 4, along with the die-cast parts above it, to rise, causing it to detach from the rollers 3 and be stably supported on the rubber support rollers 17 of the drive plate 4. At the same time, the second motor 18 drives the spline shaft 19 to rotate, which in turn drives the drive plate 4 and the die-cast parts on it to rotate around the shaft through the spline sleeve 20. The ball bearings 22 on the telescopic ends of the hydraulic cylinders 21 roll in the annular grooves 23 at the bottom of the drive plate 4, providing support and allowing the drive plate 4 to rotate and rise smoothly. During the process, the first motor 14 on the two inspection frames 2 drives the screw 7 to rotate through the pulley 15 and belt 16, which drives the mounting sleeve 8 to move vertically, thereby adjusting the inspection height of the vision probe 5 and the supplementary light ring 6. In addition, the horizontal distance of the vision probe 5 can be flexibly adjusted by sliding the positioning rod 9 and using the positioning pin 12 to be inserted into different positioning holes 10 to adapt to die-cast parts of different sizes. Finally, as the drive plate 4 drives the die-cast part to rotate, the two vision probes 5 collect images of its surface from all directions and transmit the data to the external display and control equipment to complete efficient and accurate blind-spot-free appearance inspection.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
