Description

Technical Field

[0001] This utility model relates to an automatic strip cutting and arranging device, belonging to the field of semiconductor laser strip processing technology. Background Technology

[0002] Semiconductor lasers possess a range of advantages, including small size, high output power, light weight, and high reliability, making them a core technology in optoelectronics. They have wide applications in laser ranging, laser communication, automatic control, and laser medicine. Currently, countries worldwide are paying close attention to the theoretical applications of key process technologies in semiconductor laser fabrication and are continuously accelerating research into semiconductor lasers. During laser manufacturing, the laser bars are typically arranged according to different cavity lengths; however, this process often introduces numerous defects, affecting the laser's lifespan and reliability.

[0003] The bar is a core component of a high-power semiconductor laser. Its cavity length, cavity surface quality, and front width all affect key performance characteristics such as laser reliability, lifespan, and output. Furthermore, a coating is applied to the cavity surface to improve the reflectivity of the bar. Therefore, improving the cavity surface quality and coating of the chip bar is crucial for improving laser quality. Currently, the bar is manually placed into the fixture fixing point. This process can lead to cavity surface contamination and damage, affecting product yield. Additionally, current limitations prevent the integration of the bar cleaving and the bar fixing point into a single device, restricting production efficiency.

[0004] Currently, the main method involves manually placing the strips into a fixture using a suction pen. This facilitates the movement of the fixture to the next process step for cavity surface coating. Chinese patent document CN114883906A discloses a method for fabricating the cavity surface of a semiconductor laser chip. This cleaving device integrates the dicing and splitting processes through XYZ three-axis motion, achieving automation and precision machining. A diamond cutter head moves along the X and Y axes, applying force to the workpiece's side surface to generate initial cleaving cracks. The diamond cutter head is conical in shape, applying point force to precisely control the crack's location and depth. Subsequently, the splitting cutter moves along the Z axis, applying a splitting load to the workpiece's upper surface, thus splitting the strips. However, manual placement into the fixture is still required afterward; therefore, the technical solution provided by this patent cannot fundamentally solve the problem of cavity surface damage during placement. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic strip cutting and arranging device to solve the problem of surface damage during strip placement.

[0006] The technical solution of this utility model is as follows: An automatic strip cutting and arranging device includes a support platform, an operating table on the support platform, and a strip placement platform on the operating table. A cutting knife and a camera are mounted above the strip placement platform via a support structure. Strip arranging plates are mounted on both sides of the top surface of the strip placement platform. A pressing knife is mounted on one side above the strip placement platform, and the pressing knife is connected to one side of the strip placement platform via a two-dimensional moving bracket. An inclined slide is mounted on the side of the strip placement platform away from the two-dimensional moving bracket. Two clamping points are located on the side of the operating table near the slide, and a clamp is positioned between the two clamping points. An arranging knife is mounted on the side of the clamp away from the operating table, and the arranging knife is connected to the operating table via a translation mechanism.

[0007] The medium pressure knife presses the bar strip workpiece by moving up and down a two-dimensional moving bracket, and then pushes out and pulls back the bar strip workpiece by moving left and right a two-dimensional moving bracket; the straightening knife is driven to move left and right by a translation mechanism, pushing the bar strip block that falls from the slide table to the fixture to be placed neatly, without contacting the cavity surface.

[0008] According to a preferred embodiment of the present invention, the support structure includes a support frame, which is connected to the bearing platform via an X-axis lead screw device. The support frame is vertically provided with a Y-axis lead screw device, and a cutting head is connected to the support frame via the Y-axis lead screw device. The camera and the cleaving knife are located below the cutting head.

[0009] In this invention, the X-axis lead screw device controlled by the motor drives the support frame to move along the X-axis, thereby the support frame drives the cutter head and camera to move along the X-axis. At the same time, the Y-axis lead screw device controlled by the motor drives the cutter head and camera to move along the Y-axis, thereby realizing two-dimensional movement of the cutter head along the X-axis and Y-axis.

[0010] According to a preferred embodiment of the present invention, a plurality of vacuum holes are provided on the side of the bar placement platform near the slide, and the vacuum holes are connected to a vacuum pump.

[0011] In this invention, the vacuum hole uses a vacuum pump to draw air and fix the bar strip workpiece to be cleaved onto the bar strip placement platform, which facilitates subsequent bar strip cleaving.

[0012] According to a preferred embodiment of the present invention, the cutting head portion of the cleaving knife is provided with a probe.

[0013] According to a preferred embodiment of the present invention, the translation mechanism is a cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0014] According to a preferred embodiment of the present invention, the bar workpiece is made of semiconductor material, with a length of 26~30mm, a width of 10~12mm, and a thickness of 0.15~0.3mm.

[0015] How to use: The workpiece to be cleaved is placed on the workpiece placement table. The pressure cutter is controlled by a two-dimensional moving bracket to press the workpiece down and move it along the X-axis to the appropriate position. The vacuum pump is started, and the workpiece is sucked and fixed through the vacuum hole. The camera determines the position of the workpiece, and the X-axis screw device moves the support frame, thereby moving the cutter head and cleaving cutter above the position to be cleaved on the workpiece. The Y-axis screw device moves the cutter head down, thereby moving the cleaving cutter down to cleave the workpiece. Then, the two-dimensional moving bracket controls the pressure cutter to push out, and the cleaved workpiece falls from the slide into the fixture. The straightening cutter is driven by a translation mechanism to align the workpiece in the fixture, which is convenient for subsequent cavity surface coating treatment.

[0016] The beneficial effects of this utility model are as follows: 1. The automatic strip cutting and arranging device of this utility model can adjust the direction of the strip by cooperating with the strip straightening groove and the pressing knife, so that the strip cutting edge is parallel to the target cutting edge, simplifying the processing process before strip cutting, reducing the probability of damage to the cavity surface by manual operation, and enhancing the convenience of the device.

[0017] 2. The automatic strip cutting and arranging device of this utility model controls the stability of the strips through a vacuum hole, avoiding damage to the cutting head of the cutting knife caused by the movement of the strips during the cutting process.

[0018] 3. The automatic strip cutting and arranging device of this utility model arranges the strip blocks in the fixture in an orderly manner with a straightening knife, reducing damage to the cavity surface caused by manual operation and improving the pass rate of strip processing.
