Description

Component two-way adjusting and clamping device Technical Field The invention relates to the technical field of electronic component testing, in particular to a component bidirectional adjusting and clamping device. Background With the development of the electronic industry, the reliability requirements of electronic components are increasing. The weldability is used as a key index for measuring the welding reliability of the lead wires of the components, and the testing method is very important. Currently, main standards such as GJB 360B-2009, GJB 128B-2021 and GJB 548C-2021 all have clear weld groove method instead of wetting weighing method to become the main method for weldability test. The soldering bath method requires that the components complete solder dipping within 5 minutes after pretreatment, and in order to reduce the introduction of impurities, the adhesion of the flux and the solder should be reduced as much as possible. The clamping structure is required to have the following characteristics that (1) the clamping structure can meet the requirements of specific dipping angles and depth, and can be used for dipping in different directions for multiple times (for components in multiple leading-out end directions, such as airfoil type, J type and L type packaging, n times of dipping are usually needed, and n can reach 2 or 4 times) preferably without changing a clamp, and (2) the clamping structure has good universality and reliability, can be used for firmly clamping components in different sizes, and can avoid shaking, vibration or falling. The size range of the metal lead packaging components (such as airfoil, J-type and L-type) is wide (body length: 2.80-53.50mm, body width: 1.20-16.50 mm), and the dipping requirements are accurate (generally 90 degrees of dipping angle and specific depth requirements are met). The clamping structure in the prior art is designed for a welding process or an old wetting weighing method, and the following defects generally exist: 1. The non-disassembly direction adjustment can not be realized, and for components needing to be immersed in different directions for many times, the existing fixture generally needs to disassemble the components and reinstall the direction adjustment, so that the operation time is greatly prolonged, the requirement of completing the immersion within 5 minutes is difficult to meet, and the components are easy to disassemble and assemble frequently or pollution is introduced. 2. Poor versatility, lack of a universal clamping scheme that can accommodate a wide range of sizes (especially 1.2mm-10.0mm for medium-sized components) and reduce solder flux adhesion. 3. The positioning accuracy is insufficient, an effective fine adjustment alignment mechanism is lacked, components are easy to incline in installation, and the uniformity of the immersion depth and the angle is affected. Therefore, a new clamping structure is needed to solve the above-mentioned problems in the prior art and meet the requirement of high-standard weldability test.

Optionally, each alignment unit comprises a clamping block, an alignment block, a pressing plate and a fixing pin, wherein a first through hole penetrating through the clamping block is formed in the clamping block, a second through hole penetrating through the pressing plate is formed in the pressing plate, the first through hole corresponds to the second through hole, the alignment block is movably arranged in the first through hole and the second through hole and used for performing alignment fine adjustment on the upper end face and the lower end face of the component, corresponding third through holes are formed in the clamping block and the alignment block and used for enabling the fixing pin to penetrate into the clamping block and the alignment block to be fixedly connected, and the clamping block is fixedly connected with the pressing plate, wherein the clamping blocks in the two alignment units clamp the left end and the right e
