Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a positioning mechanism for a metal plate defect detection device. Background Technology

[0002] Metal sheets are decorative panels made from metal as the base material through various processes. Common metal sheets include aluminum and aluminum alloy base materials, steel plate base materials, stainless steel base materials, and copper base materials. These sheets are characterized by easy processing, good formability, high fire resistance, rich colors, diverse forms, and strong plasticity. To ensure the production quality of metal sheets, defect detection devices are often used to inspect them before they leave the factory.

[0003] A search revealed that patent application CN201820750783.9 discloses a surface defect detection device for metal components, comprising an outer casing. A base casing is fixedly connected to the bottom of the outer casing on opposite sides. A motor is fixedly connected to one side of the bottom inner wall of the base casing, and a fixing plate is fixedly connected to one side of the top inner wall of the base casing. A turbine is rotatably connected to the back of the fixing plate via a rotating shaft, and a first pulley is fixedly connected to the surface of the fixing plate via a rotating shaft. A second pulley is fixedly connected to one end of the motor output shaft, and the surfaces of the first and second pulleys are connected via belt drive. This invention, by fixing the fixing plate to one side of the top inner wall of the base casing, rotatably connecting the turbine to the back of the fixing plate via a rotating shaft, and fixing the first pulley to the surface of the fixing plate via a rotating shaft, allows for height adjustment of the detection probe, enabling the detection of metal components of different heights and improving detection accuracy.

[0004] However, this patent has its shortcomings. The defect detection device lacks a structure for positioning the metal sheet. In actual use, after the staff places the metal sheet directly on the placement table, the inability to position the metal sheet can cause a deviation between the placement of the metal sheet and the detection head. This results in the detection head failing to detect parts of the sheet, requiring subsequent readjustment of the sheet's position for inspection, which can easily affect the efficiency of sheet inspection. Furthermore, the detection head in this device is fixedly mounted on the top plate and its position cannot be adjusted. When inspecting some long sheets, the detection head cannot completely cover the entire sheet. During the inspection process, the staff needs to push the sheet from front to back under the detection head for inspection, which is quite troublesome and laborious.

[0005] Therefore, we propose a positioning mechanism for a metal plate defect detection device. Utility Model Content

[0006] The purpose of this invention is to provide a positioning mechanism for a metal plate defect detection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism for a metal plate defect detection device, comprising a base and two movable frames. A sliding groove is provided within the base, and a bidirectional threaded rod is rotatably connected within the sliding groove. Two U-shaped seats are threaded onto the bidirectional threaded rod.

[0008] Optionally, a mounting bracket is fixedly sleeved on the outside of the two movable frames on the base. A hydraulic cylinder is fixedly installed at the top of the mounting bracket. The output end of the hydraulic cylinder extends out of the bottom end of the mounting bracket and is fixedly installed with a detector. The detector facilitates the detection of metal plates.

[0009] Optionally, a first motor is fixedly installed at the front end of each of the two movable frames, and the output ends of the two first motors are respectively fixedly installed on the corresponding transmission rods. The rotation of the transmission rods by the first motors is beneficial to the use of this equipment.

[0010] Optionally, a motor is fixedly installed on the right side of the base, and the output end of the motor is fixedly installed on the bidirectional threaded rod. The motor drives the bidirectional threaded rod to rotate, which is beneficial to the use of this equipment.

[0011] Optionally, the bidirectional threaded rod is provided with two opposing threads, and the two U-shaped seats are respectively sleeved on the corresponding threads. This design is beneficial to the use of this equipment.

[0012] Optionally, anti-slip rubber sleeves are fixedly fitted on the outer sides of the multiple rollers, and the top ends of the multiple rotating shafts extend out of the upright and are fixedly installed with limit plates. The anti-slip rubber sleeves increase the friction between the rollers and the metal sheet when they come into contact, which facilitates the conveying of the metal sheet.

[0013] Optionally, a second motor is fixedly installed on the inner wall of the rear end of each of the two uprights, and the output ends of the two second motors are respectively fixedly installed on the corresponding limit rods. The rotation of the limit rods by the second motors is beneficial to the use of this equipment.

[0014] Optionally, a control host is fixedly installed at the front end of the base, which facilitates the control of the equipment.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

A support plate 8 is fixedly installed on the side of each of the two movable frames 6 that is close to each other.

[0024] A mounting bracket 2 is fixedly fitted on the outer side of the two movable frames 6 on the base 1. A hydraulic cylinder 4 is fixedly mounted on the top of the mounting bracket 2. The output end of the hydraulic cylinder 4 extends out of the bottom of the mounting bracket 2 and is fixedly mounted with a detector 3. The detector 3 facilitates the inspection of metal plates. A first motor 9 is fixedly mounted on the front end of each of the two movable frames 6. The output ends of the two first motors 9 are respectively fixedly mounted on the corresponding transmission rods 14. The rotation of the transmission rods 14 by the first motors 9 is beneficial to the use of this equipment. A motor 15 is fixedly mounted on the right side of the base 1. The output end of the motor 15 is fixedly mounted on the bidirectional threaded rod 10. The rotation of the bidirectional threaded rod 10 by the motor 15 is beneficial to the use of this equipment. The bidirectional threaded rod 10 is provided with two opposing sections. The machine features threads, with two U-shaped seats 12 respectively fitted onto the corresponding threads. This design facilitates the use of the equipment. Anti-slip rubber sleeves 18 are fixedly fitted on the outer sides of multiple rollers 17. The top ends of multiple rotating shafts 16 extend beyond the support frame 7 and are fixedly installed with limit plates 19. The anti-slip rubber sleeves 18 increase the friction between the rollers 17 and the metal sheet, facilitating the conveying of the metal sheet. Second motors 20 are fixedly installed on the inner walls of the rear ends of the two support frames 7. The output ends of the two second motors 20 are respectively fixedly installed on the corresponding limit rods 21.

[0025] Working principle: In use, the metal plate to be tested is placed on the two support plates 8, so that the rear end of the metal plate abuts against the two limit rods 21. The positioning switch is turned on, at which point the motor 15 drives the bidirectional threaded rod 10 to rotate, causing the two U-shaped seats 12 to drive the two moving frames 6 to slide towards each other. Multiple rollers 17 then position the metal plate on both sides, keeping the metal plate centered on the machine base 1, directly below the detector 3. Then the detection switch is turned on, at which point the two second motors 20 drive the limit rods 21 to rotate away from each other. The rear end of the metal plate loses its limit, and the detector 3 inspects the metal plate. Simultaneously, the two first motors 9 work to drive the transmission rod 14 and multiple worm gears 22 to rotate. The multiple worm gears 22 drive multiple worm wheels 13, rotating shaft 16 and roller 17 to rotate. At this time, the metal plate is conveyed from front to back between the two uprights 7 and passes through the bottom of the detector 3 to complete the detection. This positioning mechanism for the metal plate defect detection device is easy to use. The above components can position the metal plate to be detected before detection, ensuring that the detector 3 can perform a comprehensive detection of the metal plate at one time, thereby further improving the detection efficiency. At the same time, it can convey the metal plate for detection during the detection process without manual pushing, making the detection process more convenient and labor-saving.
