Technical Field
[0001] This utility model belongs to the technical field of electronic testing equipment, specifically relating to a quick-release structure for probe cards. Background Technology
[0002] With the continuous development of electronic technology, probe cards play a crucial role in the testing of electronic products. During the assembly process, probe cards need to be accurately installed in specific positions to ensure the accuracy and reliability of the tests. However, existing quick-release structures for probe cards have some problems when adjusting the quick-release position;
[0003] Currently, traditional quick-release probe card structures typically employ simple mechanical fixing methods. When adjusting the position, only coarse adjustments are possible, easily resulting in excessive or insufficient adjustment distances. This necessitates multiple adjustments during actual operation, wasting significant time and effort. Furthermore, the low adjustment precision leads to inaccurate positioning, affecting the installation quality and testing results of the probe card. In addition, existing quick-release structures lack effective limit and fine-tuning devices during adjustment, making it difficult for operators to accurately control the adjustment distance and direction. This not only increases the difficulty of operation but may also lead to probe card damage or unstable installation, impacting the reliability and safety of testing.
[0004] In summary, to address the issues with position adjustment in existing probe card quick-release structures, a novel quick-release structure for probe cards is needed. This structure should enable precise position fine-tuning, improve the accuracy and efficiency of adjustment, and ensure the installation quality and testing effectiveness of the probe cards.

[0015] This invention adds a novel position fine-tuning device inside the quick-assembly top seat, with its top end fixedly connected to the quick-assembly platform at the top of the quick-assembly top seat. The position fine-tuning device uses a fine-tuning screw to drive a T-shaped fine-tuning slider to move back and forth, thus fine-tuning the position of the quick-assembly platform. This allows for more accurate assembly of the probe card after the adsorption quick-assembly head is fixed in place. During probe card assembly, extremely high positional accuracy is required. The position fine-tuning device enables precise adjustment of the quick-assembly platform, resulting in a more accurate fit between the adsorption quick-assembly head and the probe card, thereby significantly improving assembly accuracy. The precision of the quick-assembly structure reduces assembly errors and defective products caused by positional deviations. Furthermore, different models of probe cards may differ in size and installation requirements. The positional fine-tuning device allows this quick-assembly structure to adapt to different specifications of probe cards. By fine-tuning the position of the quick-assembly platform, it meets the assembly needs of various probe cards, improving the versatility of the quick-assembly structure. In practical use, if inaccurate assembly positions are found or adjustments are needed, the positional fine-tuning device allows for convenient and quick adjustments without disassembling the entire quick-assembly structure, greatly reducing the difficulty and cost of adjustment and maintenance.

A cylinder plunger is installed inside the quick-release cylinder 8, and a cylinder shaft 7 is installed at the bottom end of the cylinder plunger. The bottom end of the cylinder shaft 7 is located on the lower side of the outer wall of the bottom end of the quick-release cylinder 8. A suction-type quick-release head 11 is installed at the bottom end of the cylinder shaft 7. The suction-type quick-release head 11 is located on the upper side of the quick-release platform 6. Pressurization and depressurization inside the quick-release cylinder 8 can respectively drive the cylinder plunger to move downwards and upwards. This quick-release structure mainly consists of a quick-release housing 2, a screw-fixed base plate 12, a cylinder mounting base 10, a quick-release top seat 4, a quick-release platform 6, and a mounting bracket. The device consists of a foot 1, a maintenance door 3, a quick-assembly cylinder 8, and an adsorption-type quick-assembly head 11. During operation, the quick-assembly cylinder 8 is pressurized and depressurized to control the up-and-down movement of the cylinder plunger, which in turn drives the cylinder shaft 7 and the adsorption-type quick-assembly head 11 to move up and down. When it is necessary to assemble the probe card, the quick-assembly cylinder 8 is pressurized, pushing the cylinder plunger downward, so that the adsorption-type quick-assembly head 11 approaches the probe card on the quick-assembly platform 6 and adsorbs and fixes the probe card. After the assembly operation is completed, the quick-assembly cylinder 8 is depressurized, the cylinder plunger moves upward, and the adsorption-type quick-assembly head 11 moves away from the quick-assembly platform 6 so as to carry out the next assembly operation.
[0025] like Figure 1 , Figure 4 and Figure 5 As shown, the quick-installation top seat 4 is equipped with a position fine-tuning device 5.

A screw is installed inside both the T-shaped sealing block 16 and the center of the rear end of the quick-installation top seat 4. The two screw holes 18 have their centers longitudinally aligned. A T-shaped fine-tuning slider 17 is provided in the T-shaped fine-tuning groove 13. The top of the T-shaped fine-tuning slider 17 is fixedly connected to the bottom of the quick-mount platform 6. The position fine-tuning device 5 also includes an operating knob 15, screw holes 18, fine-tuning screws 19, and fine-tuning screw holes 20. Fine-tuning screws 19 are connected to the two screw holes 18, and the fine-tuning screws 19 pass through the fine-tuning screw holes 20 inside the T-shaped fine-tuning slider 17. The front end of the fine-tuning screw 19... An operating knob 15 is provided, which can drive the fine-tuning screw 19 to rotate clockwise and counterclockwise. The clockwise and counterclockwise rotation of the fine-tuning screw 19 can push the fine-tuning screw hole 20 back and forth through the thread action.
