Description

Technical Field

[0001] This utility model relates to the field of metal product manufacturing technology, and in particular to a surface scratch detection device for metal product manufacturing. Background Technology

[0002] A surface scratch detection device for metal product manufacturing is a high-tech instrument primarily used to detect and locate minute scratches on metal surfaces. This device typically employs optical imaging technology, emitting light and collecting the reflected light after it passes through the metal surface. The intensity and distribution of the reflected light are then analyzed to determine the presence of scratches or other damage on the metal surface.

[0003] Most existing surface scratch inspection devices for metal product manufacturing can only inspect one side at a time. If multiple sides need to be inspected, the device must be operated or adjusted multiple times, which greatly increases the inspection time and limits the flexibility of the inspection.

[0004] Therefore, most surface scratch inspection devices for metal product manufacturing can only inspect one side at a time. If multiple sides need to be inspected, the device must be operated or adjusted multiple times, which greatly increases the inspection time and limits the flexibility of the inspection. A surface scratch inspection device for metal product manufacturing can be designed to quickly flip the metal plate when it is necessary to inspect the other side. This solves the problem that most devices can only inspect one side at a time, and if multiple sides need to be inspected, the device must be operated or adjusted multiple times, which greatly increases the inspection time and limits the flexibility of the inspection. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a surface scratch detection device for metal product manufacturing. This surface scratch detection device for metal product manufacturing aims to solve the technical problem that under the prior art, most of them can only detect one side during the detection. If multiple sides need to be detected, the device needs to be operated or adjusted multiple times, which greatly increases the detection time and limits the flexibility of the detection.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 4 This utility model provides an embodiment of a surface scratch detection device for metal product manufacturing, comprising a mounting plate 1, a first motor 601, and a scratch detection assembly; a support column 2 is provided at the lower end of the mounting plate 1, and a mounting frame 3 is provided at the upper end of the support column 2, with two sets of mounting frames 3; a first conveyor belt 4 and a second transmission belt 5 are provided on the inner side of the mounting plate 1; the scratch detection assembly is provided at the lower end of the mounting frame 3; a centering alignment assembly is provided on the outer side of the mounting plate 1; the first motor 601 is provided on one side of the mounting plate 1; a worm gear 602 is provided at the output end of the first motor 601; a worm wheel 603 is provided on one side of the worm gear 602, and the worm gear 602 meshes with the worm wheel 603. A turning roller 604 is provided inside the worm gear 603. A groove is opened at the corresponding position of the mounting plate 1 and the turning roller 604. The turning roller 604 is rotatably connected to the inside of the groove of the mounting plate 1. The groove opened at the corresponding position of the mounting plate 1 and the turning roller 604 has a limiting effect when the turning roller 604 rotates inside the groove. The metal plate is driven to the inside of the groove of the turning roller 604 by the first conveyor belt 4. Then the first motor 601 is started. The first motor 601 drives the worm 602 to rotate. The worm 602 drives the worm gear 603 to rotate. The worm gear 603 drives the turning roller 604 to rotate. The turning roller 604 turns the metal plate and flips it onto the second transmission belt 5.

[0022] Please see Figure 2In this embodiment, the scratch detection component includes an industrial CCD camera 701. The industrial CCD camera 701 is mounted on the lower end of the mounting bracket 3, and an LED white light 702 is mounted on the lower end of the mounting bracket 3. Scratch inspection is performed by using the industrial CCD camera 701. The industrial CCD camera 701 has high image quality, wide dynamic range, high sensitivity, and strong anti-interference ability. Two sets of LED white lights 702 are provided, located on both sides of the industrial CCD camera 701. By setting two sets of LED white lights 702, the scratch will produce a height difference when the light is uniform, resulting in different brightness, and thus it is easier to identify.

[0023] Please see Figure 4 In this embodiment, the centering alignment component includes a support frame 801, a second motor 802 at the lower end of the support frame 801, a rotating shaft 803 at the output end of the second motor 802, a cam 804 fixedly connected to the outer side of the rotating shaft 803, a connecting rod 805 rotatably connected to the outer side of the cam 804, a push rod 806 rotatably connected to the inner side of the connecting rod 805, a guide post 807 on one side of the mounting plate 1, a push block 808 on one side of the push rod 806, and a nylon block 809 on one side of the push block 808. Slide grooves are provided at corresponding positions of the guide post 807 and the push rod 806, allowing the push rod 806 to slide. The guide post 807 is connected to the inside of the slide groove. The corresponding positions of the guide post 807 and the push rod 806 are provided with slide grooves, which limit the sliding of the push rod 806 inside the slide groove. There are two sets of connecting rods 805, push rods 806, guide posts 807, push blocks 808 and nylon blocks 809. The two sets of connecting rods 805, push rods 806, guide posts 807, push blocks 808 and nylon blocks 809 are symmetrically distributed on both sides of the first conveyor belt 4. The push blocks 808 are symmetrically arranged on both sides of the first conveyor belt 4, so that the sliding push blocks 808 push the metal plate to the middle of the first conveyor belt 4.

[0024] When using this device, the LED white light 702 is turned on. The metal plate is placed on the first conveyor belt 4, and the second motor 802 is started. The second motor 802 drives the rotating shaft 803 to rotate, which in turn drives the cam 804 to rotate. The cam 804 drives the connecting rod 805 to move, which in turn drives the push rod 806 to slide inside the guide post 807. The push rod 806 drives the push block 808 to move, which in turn drives the nylon block 809 to push the metal plate, placing it in the middle of the first conveyor belt 4. The first conveyor belt 4 then moves the metal plate to below the industrial CCD camera 701. Light is emitted by the LED white light 702, and the industrial CCD camera 701 collects the reflected light after it passes over the metal surface. The intensity and distribution of reflected light are analyzed to determine whether scratches or other damage exist on the metal surface. Once one side of the metal plate is inspected, the other side is inspected. The metal plate is moved to the slot of the flip roller 604 via the first conveyor belt 4. Then, the first motor 601 is started, driving the worm gear 602 to rotate. The worm gear 602 drives the worm wheel 603 to rotate, which in turn drives the flip roller 604 to rotate. The flip roller 604 flips the metal plate onto the second transmission belt 5. The second transmission belt 5 moves the metal plate to the lower end of the industrial CCD camera 701. Light is emitted by the LED white light lamp 702, and the industrial CCD camera 701 collects the reflected light after it passes through the metal surface for inspection of the other side. The inspection is then complete.

[0025] Through the above steps, the metal plate is driven to the inside of the slot of the flipping roller 604 by the first conveyor belt 4. Then, the first motor 601 is started, which drives the worm gear 602 to rotate. The worm gear 602 drives the worm wheel 603 to rotate. The worm wheel 603 drives the flipping roller 604 to rotate. The flipping roller 604 flips the metal plate and flips it onto the second transmission belt 5.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
