Description

Technical Field

[0001] This utility model belongs to the field of laser processing equipment technology, specifically relating to a magnetic adsorption type chassis door and a laser processing device. Background Technology

[0002] In the field of laser processing equipment, the sealed door of the processing chamber is a key component to ensure processing accuracy, operational safety, and equipment protection. Traditional equipment enclosure doors mostly adopt simple hinged single-door or latch-type fixed door structures, which generally have the following defects:

[0003] Insufficient sealing: Traditional mechanical latches or bolt structures cannot guarantee a completely seamless and tight closure between the door and the outer shell. During laser processing, especially precision machining, the intrusion of external dust and moisture, or even slight laser leakage, can affect processing quality, damage optical components, and even pose safety risks to operators.

[0004] Lack of ease of operation and functionality: Opening a single door requires a large operating space, which is extremely inconvenient in workshops with limited space. In addition, traditional door structures have limited functionality, usually only having two states: "open" and "closed". They cannot stably stay in any position during the opening process, making it difficult to meet the flexible needs of door opening and closing under different working conditions. For example, when observing, loading and unloading materials, or dissipating heat, it is necessary to support the door with hands or other tools.

[0005] Complex structure and reliability issues: To achieve effective sealing, some designs employ complex multi-point locking mechanisms or pneumatic / electric assisted closing devices, which not only increases manufacturing costs and failure rates but also makes daily maintenance cumbersome.

[0006] Therefore, there is an urgent need for a chassis door system that can achieve efficient and tight sealing, is easy to operate, flexible in function, and has a stable and reliable structure, so as to improve the overall performance of laser processing equipment and user experience.

[0032] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, article, or apparatus.

[0033] This utility model embodiment provides a magnetic adsorption type chassis door, such as... Figure 1-3 As shown, it includes a processing equipment housing 1, a folding door mechanism 2, and a magnetic suction part 3;

[0034] The processing equipment housing 1 is used for laser processing of the workpiece;

[0035] The folding door mechanism 2 surrounds the processing area disposed on the outer shell 1 of the processing equipment and is used to close the processing area in the closed state; it is also used to open the processing area in the non-closed state.

[0036] The magnetic suction part 3 is disposed at the end of the folding door mechanism 2 and is used to magnetically connect the folding door mechanism 2 to the processing equipment housing 1 when the folding door mechanism 2 is in the closed state.

[0037] This utility model uses a folding door mechanism 2 as an integrated solution to replace a single door, saving the operating space required for opening. More importantly, it encloses the processing area during laser processing, reducing the harm of the laser source to the human eye. Furthermore, by setting up a magnetic suction part 3, the folding door mechanism 2 and the processing equipment housing 1 are quickly connected and separated by magnetic attraction. This overcomes the problems of uneven sealing pressure and easy gaps caused by processing tolerances or wear in traditional mechanical locks. It can effectively prevent laser leakage, dust intrusion, and external interference, greatly improving the cleanliness, safety, and stability of the laser processing process. It is particularly suitable for high-precision laser processing environments.

[0038] In some embodiments, the folding door mechanism 2 includes a door assembly 21, a door hinge 22, and a door latch 23;

[0039] One side of the door assembly 21 is hinged to one side of the processing equipment housing 1 via a door hinge 22, and the other side is provided with a door latch 23; the door latch 23 is engaged with the other side of the processing equipment housing 1.

[0040] In some embodiments, the folding door mechanism 2 further includes a door latch 23, which is disposed on the side of the door assembly 21 and is used to engage with the corresponding edge on the processing equipment housing 1 when closed to form a mechanical positioning.

[0041] For example, the door latch 23 is an elastic snap-fit ​​structure, which is preferably made of engineering plastics (such as POM or nylon) with good wear resistance and a certain degree of elasticity.

[0042] The door latch 23 is reliably installed on the free end side of the door assembly 21 by means of screw fastening or snap-fit.

[0043] On the outer casing 1 of the processing equipment, at a position corresponding to the door latch 23, there is a matching bayonet or flange structure.

[0044] When the user pushes the door assembly 21 toward the closed position, the tip of the door latch 23 first contacts the corresponding edge of the processing equipment housing 1. Since the door latch 23 itself or its mounting base is designed with an elastic deformation part, under the action of continuous closing force, the door latch 23 will undergo elastic deformation, and its hook part can slide past the edge of the housing.

[0045] When the door assembly 21 moves to the predetermined position of being fully closed, the latch 23 quickly rebounds under the action of elastic restoring force and engages in the slot on the processing equipment housing 1, forming a stable and reliable mechanical positioning.

[0046] In some embodiments, the magnetic suction part 3 includes a first magnetic suction element disposed on the side of the door assembly 21 for magnetic attraction connection with the corresponding edge on the processing equipment housing 1 when closed.

[0047] It should be noted that this is on the premise that the outer casing 1 of the processing equipment is also made of metal.

[0048] Even after the door assembly 21 has been initially secured by the door latch 23, its tightness of closure is not yet sufficient to meet the sealing requirements of laser processing. Subsequently, the magnetic suction part 3, located on the same or different sides of the door assembly 21, begins to function, making the sealing surface between the door assembly 21 and the processing equipment housing 1 completely adhered, ultimately achieving an airtight or near-airtight tight closure.

[0049] In some embodiments, the magnetic attraction part 3 further includes a second magnetic attraction element, which is disposed on the other side of the processing equipment housing 1, and the first magnetic attraction element and the second magnetic attraction element attract each other.

[0050] For example, the first magnetic element is a permanent magnet, and the second magnetic element is a permanent magnet or a magnetically conductive metal sheet.

[0051] In some embodiments, the door assembly 21 includes a first door 211 and a second door 212;

[0052] One side of the first door 211 is hinged to one side of the processing equipment housing 1 via a door hinge 22; the other side of the first door 211 and one side of the second door 212 are hinged to each other via a door hinge 22, and the other side of the second door 212 is connected to the other side of the processing equipment housing 1 via a door latch 23.

[0053] In some embodiments, when the first door 211 and the second door 212 are closed, their adjacent sides abut each other, and their outer contours match the opening contour of the processing equipment housing 1, together forming a flat or continuous outer surface.

[0054] For example, the first door 211 is the same size as a front opening of the processing equipment housing 1, and its shape is a regular rectangle.

[0055] The second door 212 is designed as an "L" shaped structure. One part (the vertical part of the L-shape) is used to cover another front opening of the processing equipment housing 1, and the other part (the horizontal part of the L-shape) is used to cover part of the top opening or the side opening of the processing equipment housing 1.

[0056] After being closed, the plane of the first door 211, the second door 212, and the uncovered surface of the processing equipment housing 1 together form a flat, continuous outer surface without abrupt steps.

[0057] In some embodiments, the door hinge 22 includes a damping structure, which is a friction damping hinge or a torque hinge.

[0058] With the damping structure, users can easily stop the first door 211 and the second door 212 at any angle between the maximum and minimum opening, which is convenient for observing the processing status, picking up and putting down workpieces, or dissipating heat from the equipment.

[0059] This utility model embodiment also provides a laser processing device, including the above-mentioned magnetic adsorption type chassis door.

[0060] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
