Description

Technical Field

[0001] The utility model relates to the technical field of laser processing, in particular to a device for marking aluminum alloy with picosecond laser black. Background Art

[0002] Aluminum is a metal material commonly used in the shells of many products. For example, raw materials or finished products such as aluminum profiles and battery boxes are all pure aluminum materials. In daily life, in order to facilitate product identification, it is necessary to make a QR code on the surface of aluminum.

[0003] When making a QR code on the surface of aluminum, in the past, due to the limitation of the performance of the laser, only white marks could be made, which had a poor contrast with the original color of the metal and a high bit error rate. Therefore, the existing technology widely uses picosecond laser marking machines to make black marks on the surface of aluminum. However, the existing picosecond laser marking machines lack protection. If the operator stares at the beam of the laser marking machine for a long time, it may cause eye pain, vision loss, and even damage the lens. In addition, the existing technology often requires the assembly of aluminum materials by disassembling and assembling positioning pins, and the assembly speed is slow.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a device for picosecond laser black marking of aluminum alloy is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a device for black marking aluminum alloy using picosecond laser to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for picosecond laser black marking of aluminum alloy, comprising a chassis and a switching clamp mechanism, the chassis having a built-in switching clamp mechanism, the switching clamp mechanism comprising a base, a back plate, a panel, a boss, a groove, an insertion roller, a bar, a spring and a handle, the back plate is integrally fixed to the rear end of the base, and the panel is integrally fixed to the front end of the base, a boss is welded and fixed to the inner side of the panel, and a groove is opened in the middle of the boss, an insertion roller is slidably fitted in the middle of the groove, and the insertion roller is rotatably fitted with the panel, and the bar integrally fixed at the rear end of the insertion roller is gap-fitted with the groove, a spring is mounted on the front end of the insertion roller, and a handle is integrally fixed to the head end of the insertion roller.

[0007] Furthermore, an alarm light is bolted to the top of the chassis, and a laser box is provided at the bottom right of the chassis, and the laser box has a built-in seed source for emitting picosecond signals.

[0008] Furthermore, a damping frame is rotatably mounted in the middle of the right side of the chassis, and a display screen is provided at the end of the damping frame.

[0009] Furthermore, a main chassis is arranged at the bottom of the chassis, and a sliding drawer is arranged in the middle of the chassis, and the sliding drawer has a built-in keyboard electrically connected to the display screen.

[0010] Furthermore, a working chamber is provided on the top of the chassis, and a laser head is controlled at the top of the working chamber through a three-axis truss, and an operation window is provided on the front opening of the working chamber.

[0011] Furthermore, limiters are arranged on both sides of the bottom end of the operation window, and a lifting door panel is slidably matched with the top end of the operation window.

[0012] Furthermore, a handle is welded and fixed on the front side of the lifting door panel, and an observation window is bolted to the middle of the lifting door panel, and the observation window is an ND filter coated with a reflective film.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When the utility model is in use, a chassis is arranged outside the existing picosecond laser marking machine to achieve the effect of waterproof and dustproof, thereby extending the service life of the picosecond laser marking machine and ensuring the application accuracy. An operation window is provided at the front opening of the working chamber, which is convenient for the staff to take and place the aluminum material to be processed. When in use, the built-in seed source of the laser is controlled by the control circuit to emit a picosecond signal, which enters the scanning galvanometer after being expanded by the beam expander, and is finally emitted by the laser head with a built-in focusing field lens to make a black mark on the surface of the aluminum material. The laser head is controlled by a three-axis truss, which can adjust the focus position so that the initial position of the focus is located on the surface to be marked. In order to prevent the strong light from irritating the eyes of the staff during the laser marking process, a lifting door panel that can be slidably opened and closed is installed above the operation window. In the running state, most of the strong light can be isolated by pulling down the lifting door panel by the handle. The internal situation of the working chamber can be monitored through the observation window arranged in the middle of the lifting door panel. The observation window is an ND dimming mirror coated with a reflective film, which effectively reflects the incident light to reduce the intensity of the laser and plays an effective visual protection role.

[0015] 2. The utility model switches the setting of the clamping mechanism to put the aluminum material to be processed into the space between the opposite surfaces of the back plate and the front plate, inserts the insertion roller and passes the bar at the rear end through the bar groove, and then rotates the insertion roller by the handle. Under the elastic force of the spring, the bar is locked on both sides of the boss, so that the aluminum material can be quickly assembled. Conversely, when taking out the marked aluminum material, it is only necessary to reverse the bar and pull out the insertion roller, which can effectively improve the assembly efficiency of the aluminum material in the prior art.
