Description

Technical Field

[0001] This utility model relates to the field of laser chip manufacturing equipment technology, specifically a pulsed laser chip sintering fixture. Background Technology

[0002] In the manufacturing process of pulsed laser chips, sintering is one of the most crucial steps. This step requires precisely fixing the chip and establishing a stable electrical connection with the programming equipment to complete the programming of chip parameters and performance testing. In the existing technology, the fixtures used for sintering pulsed laser chips are mostly general-purpose clamping structures, usually using a single rigid clamp block and bolts to fix the chip, and their structural design is relatively simple.

[0003] The existing fixtures still have the following problems when in use: 1. It is difficult to balance clamping stability and flexibility. The rigid clamping blocks lack buffer adjustment capabilities. Excessive clamping force can easily cause chip pin deformation or chip body damage. Insufficient clamping force can easily cause chip displacement during sintering. At the same time, the operation of adjusting the clamping angle and tightness is cumbersome, and the ability to adapt to different specifications of chips is poor. 2. The design of the programming connection structure is unreasonable. The alignment accuracy between the chip pins and the programming equipment is low. The data line is messy and easy to be pulled loose, which can lead to data transmission interruption or signal instability during sintering, affecting the sintering quality and efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a pulsed laser chip sintering fixture, which is equipped with symmetrical elastic metal clamps with adjustable clamping adjustment components, as well as a sintering component that is precisely matched with the chip pins. This solves the problems of poor clamping stability, inconvenient adjustment, inaccurate alignment of burning connections, and unstable data transmission mentioned in the background technology.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a pulsed laser chip sintering fixture, comprising a clamping assembly, wherein a clamping adjustment assembly is configured on the clamping assembly, and a sintering assembly is connected to one end of the clamping assembly.

[0008] The clamping assembly includes two elastic metal clamps arranged symmetrically in an upper and lower configuration. The elastic metal clamps are made of beryllium bronze, which has good elasticity and conductivity, and can provide stable clamping force while reducing hard damage to the chip. Each of the two elastic metal clamps has a set of anti-slip grooves at one end, which can increase the friction during hand operation and prevent the clamp from slipping. The other end of the elastic metal clamps has bolt holes, and the two elastic metal clamps are fixedly connected by fastening bolts made of stainless steel that pass through the bolt holes, which can achieve the initial positioning and fixation of the two elastic metal clamps.

[0009] The clamping adjustment assembly includes a rotating base, a connecting shaft, and a hand-tightening screw. The rotating base is rotatably mounted on the lower elastic metal clamping block, facilitating adjustment of the adjustment direction according to operational needs. The hand-tightening screw is rotatably mounted on the upper elastic metal clamping block. The surface of the hand-tightening screw is provided with anti-slip texture, allowing for manual operation without tools. The rotating base has a threaded hole for threaded connection of the hand-tightening screw. The clamping gap between the two elastic metal clamping blocks can be precisely adjusted by the cooperation of the hand-tightening screw and the threaded hole.

[0010] The sintering assembly includes a programmer fixedly mounted on one end of an elastic metal clamp. The programmer and the elastic metal clamp are fixed by welding, ensuring a stable and reliable connection. Both programmers have multiple chip pin receiving slots arranged in an array at their opposite ends, enabling precise one-to-one positioning of the chip pins. A data cable connects the two programmers to enable data communication between them. The end of the data cable away from the programmer is connected to a data connector, which uses a USB-C interface, offering advantages such as high transmission speed and convenient plugging and unplugging.

[0011] As a further improvement of this utility model: the upper elastic metal clamping block has a rotating mounting groove for the hand-tightening screw to rotate and assemble. The inner wall of the rotating mounting groove has a smooth coating to reduce the frictional resistance when the hand-tightening screw rotates. The lower elastic metal clamping block has a receiving groove to provide installation space for the rotating seat. The receiving groove has shaft holes at both ends. The inner wall of the shaft holes has a positioning step to ensure the coaxiality of the connecting shaft after assembly.

[0012] As a further embodiment of this utility model: the rotating seat is set in the receiving groove, and a gap of 0.5-1mm is left between the rotating seat and the receiving groove to facilitate the flexible rotation of the rotating seat. The connecting shaft is rotatably adapted to the shaft hole, and the two ends of the connecting shaft are designed with rounded corners to avoid scratching the inner wall of the shaft hole during assembly.

[0013] As a further improvement of this utility model: the two elastic metal clamps have assembly grooves on one side facing each other. The size of the assembly grooves is precisely matched with the outer size of the programmer, which can realize the quick positioning and installation of the programmer. The two assembly grooves have through grooves at opposite ends for the data cable to pass through. The inner wall of the through groove is provided with a rubber protective sleeve to prevent the data cable from being worn by sharp edges.

[0014] As a further improvement of this utility model: each group of anti-slip grooves consists of multiple grooves, which are distributed parallel to each other along the length of the elastic metal clamp. The depth of the anti-slip grooves is 0.3-0.5mm, and the spacing between adjacent grooves is 1-2mm. This can maximize the anti-slip effect while ensuring the structural strength of the elastic metal clamp.

[0015] As a further improvement of this utility model: the chip pin receiving groove is a strip-shaped groove adapted to the shape of the pulse laser chip pin. The inner wall of the chip pin receiving groove is provided with a gold-plated layer, which can reduce contact resistance and improve data transmission stability. The groove depth is 0.2-0.3mm greater than the length of the chip pin to avoid damage to the pin due to pressure.

[0016] As a further improvement of this utility model: the data cable is a flexible and bendable data cable with a shielded structure, which can effectively reduce external electromagnetic interference. Its two ends are fixedly connected to the programmer and the data connector, respectively. The connection method adopts welding and potting sealant treatment to improve the connection reliability and service life.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by setting up symmetrical elastic metal clamping blocks in conjunction with the clamping adjustment component, the elasticity of the elastic metal clamping blocks can achieve flexible clamping of the chip, avoiding chip damage caused by rigid clamping. The design of the combination of the hand-tightening screw and the rotating seat can flexibly adjust the clamping gap and angle of the two clamping blocks to adapt to the clamping requirements of different specifications of pulse laser chips. At the same time, the setting of the anti-slip groove improves the ease of operation and effectively solves the problem of insufficient clamping stability and flexibility of existing clamps.

[0019] 2. In this utility model, by setting an array of chip pin receiving slots on the programmer, the chip pins can be accurately aligned with the programmer, ensuring the stability of the electrical connection. The combination of shielded flexible data cable and USB-C data connector not only facilitates wiring and organization, but also improves data transmission rate and anti-interference capability, avoids data transmission interruption during the sintering process, and significantly improves chip sintering quality and production efficiency.
