Description

Technical Field

[0001] This invention relates to a pressing device, and more particularly to a continuous automatic pressing device. Background Technology

[0002] Metal sheets can be processed into the shells of various cabinets, boxes, electrical appliances, and vehicle bodies. In the specific processing, a pressing device is indispensable. The pressing process refers to fixing the sheet body 41 on the sheet 4 and pressing down or up the pressing part 42, which has a specific shape, to form a right-angle bend. Most pressing devices in the prior art are fixed-track pressing structures or movable modular pressing structures.

[0003] The fixed mold pressing structure can only press the edge of simple products, and different pressing sizes and shapes need to be achieved by changing the mold. The mold changing process is relatively cumbersome and affects the overall pressing efficiency. Although the moving module pressing structure is more flexible and can be programmed, it relies on the trajectory movement of the moving pressing module. The moving pressing module requires a lot of time to move during the movement process. When dealing with simple and numerous pressing areas or pressing areas with multiple varying sizes, it cannot meet the requirements of high-speed industrial production. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a continuous automatic edge pressing device. It achieves rapid acquisition of edge pressing position and size through a vision acquisition unit, and generates pressing programs for multiple programmable edge pressing head units based on the acquired size and position information. At the same time, it determines the position adjustment program of the movable template block, thereby realizing a continuous automatic edge pressing process during the material conveying process.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] The continuous automatic edge pressing device of this invention includes a sheet material conveying unit, a vision acquisition unit, two movable template blocks, multiple programmable edge pressing head units, and a position adjustment component, wherein specifically:

[0007] The sheet material conveying unit conveys the sheet material at a programmed speed;

[0009] Two movable template blocks are pressed onto the board body;

[0010] Multiple programmable edge pressing head units are connected in a row on one side of the movable template block and are pressed onto the edge pressing part of the board according to a specific pressing program;

[0011] The position adjustment component is connected to the movable template block to realize the adjustment of the vertical and horizontal positions of the movable template block.

[0012] Furthermore, the two movable template blocks are arranged symmetrically.

[0013] Furthermore, the programmable pressing head unit includes a cylinder connected to one side of the movable template block and a pressing head connected to the cylinder output rod.

[0014] Furthermore, the cylinder is a servo cylinder.

[0015] Furthermore, the vision acquisition unit includes multiple industrial cameras.

[0016] Furthermore, the sheet material conveying unit is a conveyor belt.

[0017] Furthermore, the movable template block is an L-shaped pressing block, wherein the length of the long side is 1.3 to 5 times that of the short side.

[0018] Furthermore, the position adjustment component includes a base plate, a first moving block, and a second moving block;

[0019] The base plate and the first moving block undergo longitudinal relative displacement;

[0020] The first and second moving blocks undergo lateral relative displacement.

[0021] The second movable block is connected to the movable template block.

[0022] Furthermore, a first servo motor is provided on the base plate, and a first lead screw is connected to the output shaft of the first servo motor. The first lead screw is screwed into the first moving block.

[0023] The first moving block is equipped with a second servo motor, and a second lead screw is connected to the output shaft of the second servo motor. The second lead screw is screwed into the second moving block.

[0024] Furthermore, the continuous automatic edge pressing device also includes a microprocessor, which is electrically connected to the sheet material conveying unit, the vision acquisition unit, the programmable edge pressing head unit, and the position adjustment component.

[0025] Furthermore, the microprocessor is an ARM processor.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1) This technical solution achieves rapid acquisition of the edge pressing position and size through a vision acquisition unit, and generates multiple programmable edge pressing head units based on the acquired size and position information. At the same time, it determines the position adjustment program of the movable template block, thereby realizing a continuous automatic edge pressing process during the sheet material conveying process. This high-speed, time-sequential pressing path is used to achieve the sheet material edge pressing task. The high-speed edge pressing path thus formed is extremely suitable for the requirements of high-speed industrial production.

[0028] 2) The position adjustment component in this technical solution can adjust the horizontal and vertical positions according to the obtained position and size information of the board, so that the two movable template blocks press on the board body of a specific size. At the same time, since multiple programmable edge pressing head units are connected in a row on one side of the movable template blocks, they press down on the edge pressing part of the board according to a specific pressing program, thereby realizing a highly matched time-sequential pressing path.
