Description

Technical Field

[0001] The utility model relates to the technical field of product detection devices, and more specifically to an appearance defect auxiliary inspection device. Background Art

[0002] Many workpieces such as steel screw rods or worm gears use a cold rolling forming process, where two rollers are used to extrude materials into the designed shape on a rolling mill. However, due to the influence of material structure, uneven hardness, and the machine itself, the products after rolling will inevitably have surface defects such as burrs and tooth tip suture lines deviating towards the tooth surface. It is necessary to conduct appearance inspection on the rolled products to promptly detect defects and adjust the rolling parameters.

[0003] To detect whether there are defects in the appearance of such long workpieces, it is generally to use a CCD detector to magnify the workpiece for visual observation on a display screen to determine whether there are defects in the workpiece. Currently, when using a CCD detector for inspection, the workpiece placed on the loading table needs to be removed and taken to a special CCD inspection table for inspection. This method is extremely inconvenient for long workpieces (such as 2 - 3 meters). Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an appearance defect auxiliary inspection device.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

The detector mounting frame includes a slide rail and a slider slidably arranged on the slide rail. The CCD detector is mounted on the slider and moves along with the slider when the slider moves along the slide rail. The receiving frame is provided with an aggregate groove for placing long workpieces. When the workpiece is placed in the aggregate groove, the length direction of the workpiece is parallel to the length direction of the slide rail, and the CCD detector is located above the workpiece; the CCD detector moves along the length direction of the slide rail to detect the appearance of the workpiece placed in the aggregate groove.

[0012] Further, the first aggregate plate and the second aggregate plate are arranged between the first support plate and the second support plate. The first aggregate plate is arranged close to the first support plate, and the second aggregate plate is arranged close to the second support plate.

[0013] Further, the installation height of the slide rail is greater than the installation height of the aggregate trough, so that the aggregate trough is located below the slide rail.

[0027] The present utility model provides an auxiliary inspection device for appearance defects, which is mainly applicable to the appearance inspection of workpieces with a relatively long length such as lead screws or worms.

[0028] As Figure 1 - Figure 2 described, an auxiliary inspection device for appearance defects includes a CCD detector 1, a detector mounting frame 2 and a material receiving frame 3. The detector mounting frame 2 includes a slide rail 21 and a slider 22 slidably disposed on the slide rail 21. The CCD detector 1 is mounted on the slider 22 and moves along with the slider 22 when the slider 22 moves along the slide rail 21. The material receiving frame 3 is provided with an aggregate groove 35 for placing the long-shaped workpiece 100. When the workpiece 100 is placed in the aggregate groove 35, the length direction of the workpiece 100 is parallel to the length direction of the slide rail 21, and the CCD detector 1 is located above the workpiece 100; by moving the CCD detector 1 along the length direction of the slide rail 21, the appearance of the workpiece 100 placed in the aggregate groove 35 is detected.

[0029] By moving the CCD detector 1 along the length direction of the slide rail 21 to detect the appearance of the workpiece 100 placed in the aggregate groove 35, the inspection of the appearance of the entire length of the workpiece 100 is realized, the operation is convenient, and the CCD detector 1 is mounted on the material receiving frame 3. The workpiece 100 placed on the material receiving frame 3 after processing does not need to be transferred and then subjected to appearance inspection, thereby avoiding the risk of possible damage to the workpiece 100 due to transfer, and at the same time improving the work efficiency.

[0030] It should be noted that the sliding fit between the slider 22 and the slide rail 21 can be realized by the cooperation of a set motor and a lead screw. Specifically, the output shaft of the motor is connected to the lead screw, and a nut matching the lead screw is installed on the slider 22. When the lead screw rotates, the nut drives the slider 22 to move along the slide rail 21.

[0031] It should also be noted that, as a standard device, the CCD detector 1 generally includes an industrial camera 11 and a display 12. The appearance of the workpiece 100 is captured by the workpiece camera 11 and magnified and displayed using the display 12. Those commonly available on the market can be used, and their specific structures and working principles will not be elaborated here.

[0032] As Figure 2 shown, the detector mounting frame 2 further includes a support plate. The support plate is connected to the material receiving frame 3, and the slide rail 21 is installed on the support plate. In one embodiment, there are two support plates, namely a first support plate 23 and a second support plate 24. The first support plate 23 and the second support plate 24 are arranged at intervals relative to each other along the length direction of the slide rail 21. The slide rail 21 is installed across the first support plate 23 and the second support plate 24. The first support plate 23 and the second support plate 24 serve as the support structure of the slide rail 21. Such a design provides more stable support for the slide rail 21. In this embodiment, two parallel slide rails 21 are provided on the first support plate 23 and the second support plate 24, which is beneficial to improving the stability and reliability of the movement of the slide rail 21.

[0033] As Figure 2 shown, the material receiving frame 3 includes a base 31 and a top panel 32 provided on the top of the base 31. An aggregate groove 35 is provided on the top panel 32. In this embodiment, the base 31 includes two spaced I-shaped steel structures, and the two I-shaped steel structures are connected together by two square steel pipes arranged at intervals up and down. The top panel 32 is fixed to the tops of the two I-shaped steel structures. The top panel 32 serves as the support structure of the detector mounting frame 2.

[0034] As Figure 2 shown, an aggregate plate is provided on the upper surface of the top panel 32. The length direction of the aggregate plate is perpendicular to the length direction of the slide rail 21. A plurality of aggregate grooves 35 are provided along the length direction of the aggregate plate. In one embodiment, there are two aggregate plates, namely a first aggregate plate 33 and a second aggregate plate 34. The first aggregate plate 33 and the second aggregate plate 34 are arranged at intervals relative to each other along the length direction of the slide rail 21. The workpiece 100 straddles the first aggregate plate 33 and the second aggregate plate 34 and is placed in the aggregate grooves 35 of the first aggregate plate 33 and the second aggregate plate 34.

[0035] It should be noted that, in order to move the workpieces 100 in different aggregate grooves 35 to positions convenient for the CCD detector 1 to detect, the first aggregate plate 33 and the second aggregate plate 34 are arranged to be movable along the direction perpendicular to the length direction of the slide rail 21.

[0036] As Figure 2As shown, in one embodiment, the first aggregate plate 33 and the second aggregate plate 34 are arranged between the first support plate 23 and the second support plate 24. The first aggregate plate 33 is arranged close to the first support plate 23, and the second aggregate plate 34 is arranged close to the second support plate 24. The installation height of the slide rail 21 is greater than the installation height of the aggregate chute 35, so that the aggregate chute 35 is located below the slide rail 21. The height difference between the slide rail 21 and the aggregate chute 35 is greater than the height of the workpiece 100. The purpose of such a design is that when the workpiece 100 moves along with the first aggregate plate 33 and the second aggregate plate 34, it will not be blocked by the bottom of the slide rail 21.

[0037] As Figure 2 As shown, in one embodiment, the detector mounting frame 2 further includes a column 25. The CCD detector 1 is mounted on the column 25. The lower end of the column 25 is fixedly connected to the slider 22. By providing the column 25, the mounting position of the CCD detector 1 has a certain height difference relative to the workpiece 100, which is beneficial for the industrial camera 11 of the CCD detector 1 to capture the appearance image of the workpiece 100.

[0038] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
