Description

Technical Field

[0001] This utility model belongs to the field of plate steel processing technology, specifically relating to a positioning and alignment device for an automatic plate steel loading and unloading equipment. Background Technology

[0002] In modern industrial production, sheet steel is widely used. The efficiency and precision of its processing and storage are crucial to the entire production process. During the loading and unloading of sheet steel, ensuring the accurate positioning and alignment of the steel plates is a key prerequisite for achieving efficient and high-quality processing and reasonable stacking.

[0003] Currently, there are many problems with the traditional methods of loading and unloading steel plates. Some companies still rely on manual labor for positioning and aligning steel plates. This not only consumes a lot of manpower and puts workers under great labor intensity, but also makes manual operation highly susceptible to subjective factors, resulting in inconsistent positioning accuracy. Once the positioning is deviated, subsequent processing steps such as cutting and welding will have processing errors due to the inaccurate position of the steel plate. In severe cases, it may even cause the product to be scrapped, which greatly affects production efficiency and product quality.

[0004] While some automated material handling systems can achieve basic material handling, they have significant shortcomings in positioning and alignment. For example, some equipment uses simple mechanical limiting methods, which can only roughly position steel plates of specific sizes and specifications. This is insufficient for meeting the positioning accuracy requirements of steel plates of varying sizes. Other equipment uses visual recognition technology for positioning; however, complex lighting conditions in the workshop, dirt and wear on the steel plate surface, and other factors can interfere with the accuracy of the vision system, leading to positioning failures or large errors. Furthermore, existing automated equipment often cannot dynamically adjust according to the real-time position and orientation of the steel plate during positioning and alignment, resulting in poor flexibility and an inability to adapt to changing working conditions during production.

[0005] In summary, existing plate steel loading and unloading equipment, whether manually operated or automated, cannot adequately meet production needs in terms of positioning and alignment. Developing a device that can automatically and accurately position and align plate steel during loading and unloading is of urgent practical significance for improving plate steel processing efficiency, enhancing product quality, and reducing production costs. Utility Model Content

[0006] The purpose of this utility model is to provide a positioning and alignment device for an automatic loading and unloading equipment for sheet steel. This device can automatically position and align sheet steel, significantly reducing labor costs and worker labor intensity. It also has high positioning accuracy, avoiding processing scrap due to position deviation, improving product quality, and can adapt to sheet steel of different sizes, dynamically adjusting the positioning to suit various working conditions.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A positioning and alignment device for an automatic loading and unloading equipment for sheet steel includes four mounting plates distributed at the four corners of the sheet steel body. A suction cup is mounted on the top of each mounting plate. A driving bevel gear is rotatably connected to the top of each mounting plate. Two driven bevel gears are meshed with the top of the driving bevel gear, with an included angle of 90° between the two driven bevel gears. A mounting ring is also fixed to the top of the mounting plate. A threaded rod is fixed to the end of each driven bevel gear away from the driving bevel gear, and the threaded rod is rotatably connected to the mounting ring. A sleeve is threaded to the outer side of the threaded rod, and a mounting block is fixed to the end of the sleeve away from the threaded rod.

A mounting bracket is fixed on the top of the mounting plate, and the motor is mounted on the mounting bracket. A limit structure is installed between the mounting block and the mounting fixing ring, and an up-and-down moving clamping structure is installed on the mounting block.

[0010] The limiting structure includes a limiting rod fixed to the end of the driving bevel gear, a limiting tube fixed to the side of the mounting block near the limiting rod, and the limiting rod sliding inside the limiting tube.

[0011] The up-and-down moving clamping structure includes an electric push rod installed inside the mounting block, and the stroke rod of the electric push rod is fixed vertically downward to an abutment block.

[0012] Multiple hoisting ropes are fixed to the top of the mounting plate.

[0013] It also includes a PCB chip and a controller, and the controller is electrically connected to the plurality of motors.

[0014] A flexible contact block is fixed to the side of the abutment block near the mounting plate, and the flexible contact block is made of a flexible material, namely rubber.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] Example 1:

[0026] like Figures 1-4As shown, a positioning and alignment device for an automatic loading and unloading equipment for sheet steel includes four mounting plates 1, which are distributed at the four corners of the sheet steel body 21. A suction cup 14 is installed on the top of the mounting plate 1. The suction cup 14 is used to adhere to the sheet steel body 21, thereby driving the sheet steel body 21 to be lifted. Multiple lifting ropes 15 are fixed to the top of the mounting plate 1, which can drive the sheet steel body 21 to be loaded and unloaded. A drive bevel gear 2 is rotatably connected to the top of the mounting plate 1. Two driven bevel gears 3 are meshed on the top of the drive bevel gear 2, and the included angle between the two driven bevel gears 3 is 90°. A mounting ring 5 is also fixed to the top of the mounting plate 1. A threaded rod 4 is fixed to the end of the driven bevel gear 3 away from the drive bevel gear 2, and the threaded rod 4 is rotatably connected to the mounting ring 5. A sleeve 7 is threadedly connected to the outer side of the threaded rod 4. A mounting block 10 is fixed to the end of the sleeve 7 away from the threaded rod 4.

[0027] A motor 6 is provided on the top of the active bevel gear 2, and the output end of the motor 6 is connected to the active bevel gear 2. A mounting bracket 13 is fixed on the top of the mounting plate 1, and the motor 6 is mounted on the mounting bracket 13. A limit structure is installed between the mounting block 10 and the mounting fixing ring 5.

[0028] When the mounting block 10 needs to move left or right, the motor 6 can be driven, causing the output end of the motor 6 to drive the driving bevel gear 2 to rotate. Through the meshing connection between the driving bevel gear 2 and the driven bevel gear 3, the driving bevel gear 2 can drive the driven bevel gear 3 and the threaded rod 4 to rotate. Through the threaded connection between the threaded rod 4 and the sleeve 7, and through the setting of the limiting structure, the mounting block 10 can be moved back and forth. (See attached diagram) Figure 3 The limiting structure includes a limiting rod 8 fixed to the end of the driving bevel gear 2. A limiting tube 9 is fixed to the side of the mounting block 10 near the limiting rod 8, and the limiting rod 8 slides inside the limiting tube 9. The limiting tube 9 moves with the mounting block 10, and when it slides outside the limiting rod 8, it can prevent the mounting block 10 and the sleeve tube 7 from rotating, thereby allowing the mounting block 10 to move back and forth.

[0029] The mounting block 10 is equipped with a vertically movable clamping structure.

[0030] See attached document Figure 3 The vertically movable clamping structure includes an electric push rod 11 installed inside the mounting block 10. The stroke rod of the electric push rod 11 is vertically fixed with an abutment block 12. When the electric push rod 11 is driven, it can drive the abutment block 12 to move down and make the abutment block 12 come into contact with the plate steel body 21, thereby abutting the plate steel body 21.

[0031] Example 2:

[0032] This embodiment makes further technical improvements based on embodiment 1, and the specific technical features and effects are as follows:

[0033] The device also includes a PCB chip and a controller, with the controller electrically connected to multiple motors 6. Signals can be transmitted to the controller via the PCB, enabling the controller to simultaneously control one or more motors 6. This facilitates optimal adjustment of the sheet metal body 21. (See attached diagram.) Figure 4 A flexible contact block 16 is fixed to the side of the abutment block 12 near the mounting plate 1. The flexible contact block 16 is made of flexible material, specifically rubber, which increases the contact friction between the abutment block 12 and the steel body 21 of the plate. A mounting cavity 17 is provided inside the flexible contact block 16. A first abutment piece 18 and a second abutment piece 19 are fixed to both ends of the mounting cavity 17. Electrode pieces 20 are provided on the sides of the first abutment piece 18 and the second abutment piece 19 that are close to each other. When the flexible contact block 16 is pressed... During deformation, the first abutment piece 18 and the second abutment piece 19 can move towards each other, thereby causing the two electrode pieces 20 to move closer to each other. One electrode piece 20 is connected to the external PCB, and the other electrode piece 20 is connected to the power supply. When the two electrode pieces 20 are in contact, one of the electrode pieces 20 is energized and transmits a signal to the PCB board, so that the PCB board knows that the flexible contact block 16 is deformed normally. If the two electrode pieces 20 fail to make contact at any time, the PCB board can remind the user to replace the flexible contact block 16.

[0034] The working principle of this utility model is as follows: When hoisting the steel plate body 21, if it is necessary to position and align the steel plate body 21, multiple cameras can be added around the construction site to monitor the position of the steel plate body 21 in real time. When the steel plate body 21 is too long at one end, the electric push rod 11 at that end can drive the abutment block 12 to move down to be horizontally aligned with the steel plate body 21. The motor 6 at that end can be started, thereby driving the threaded rod 4 to rotate, which can drive the abutment block 12 on the mounting block 10 to abut against the steel plate body 21, thereby pushing the steel plate body 21 and making the steel plate body 21 tend to be aligned. During the hoisting process, if the camera detects that the steel plate body 21 is tilted and elongated in one direction, the motor 6 at different positions can be started or stopped according to the implementation situation.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
