Abstract
Description
Technical Field
[0001] This invention relates to the field of semiconductor component processing technology, and more specifically to a product straightening device and its working method for mechanical processing. Background Technology
[0002] In the semiconductor component manufacturing process, the straightness of the product has a significant impact on subsequent processing and product performance. However, existing technologies lack efficient straightening mechanisms specifically designed for semiconductor component processing, leading to problems such as bending and deformation during processing. This affects processing accuracy and product quality, making it difficult to meet the semiconductor industry's requirements for high-precision components. Summary of the Invention
[0003] To solve the above-mentioned technical problems, the present invention provides a product straightening device for machining and its working method.
[0004] The specific technical solution is as follows: A product straightening device for machining is used to straighten parts with connecting holes. The straightening device includes a slide rod, a pair of positioning blocks, a pair of set screws A, a pair of set screws B, a pair of positioning pins, and a connecting rod. The slide rod includes a rod body with a threaded hole B in the middle for mounting the connecting rod, which is connected to the machine tool spindle. One end of the positioning block has a sliding hole, and the top of the sliding hole has a threaded hole C perpendicular to the sliding hole. The other end of the positioning block has a pin hole, and the side has a threaded hole D perpendicular to the pin hole. The slide rod passes through the sliding holes of the pair of positioning blocks, and the pair of positioning blocks slide along the slide rod to adjust their relative distance. Set screws A are screwed into threaded holes C to lock the position of the positioning blocks on the slide rod. The positioning pins are inserted into the pin holes, and set screws B are screwed into threaded holes D to lock the positioning pins. The positioning pins engage with the connecting holes on the parts.
[0005] It also includes a limiting block, one end of which is a limiting end and the other end is a threaded end A. A threaded hole A is opened at each end of the slide rod. The threaded end A of the limiting block is screwed into the threaded hole A to limit the extreme position of the two positioning blocks sliding on the slide rod.
[0006] One end of the set screw A is a rotating end, and the other end is a threaded end B. The threaded end B is screwed into the screw hole C to lock the position of the positioning block on the slide rod; the set screw B has the same structure as the set screw A.
[0007] One end of the positioning pin is a pin cylinder surface, which is interference-fitted with the pin hole; the other end is a pin head, which is fitted with the connecting hole on the part.
[0008] It also includes a guide sleeve, which consists of a sleeve with a central hole. The sleeve is installed in the sliding hole of the positioning block, and the sliding rod is in direct contact with the sleeve hole.
[0009] One end of the connecting rod is the connecting end, which is connected to the machine tool spindle, and the other end is the threaded end C. There is a protruding retaining flange between the connecting end and the threaded end C. After the threaded end C passes through the threaded hole B, it is limited by the retaining flange and then locked with the nut.
[0010] The working method of the product straightening device used in machining includes the following steps: (1) First, according to the length of the semiconductor part to be processed, slide the two positioning blocks along the slide bar to the appropriate position; (2) Screw the set screw A into the screw hole C to lock the position of the positioning block on the slide rod; (3) Insert a pair of locating pins into the pin holes and lock the locating pins by screwing a pair of set screws B into the screw hole D; (4) Place the semiconductor component under the positioning block, and align the positioning pin with the two connection holes at the appropriate positions on the component to complete the precise positioning; (5) The mechanism straightens the parts through relevant operations. Under the guidance of the guide sleeve, each component moves smoothly to complete the straightening process and ensure the straightness of the product parts for subsequent processing.
[0011] Compared with the prior art, the present invention has the following beneficial technical effects: This invention, through the coordinated work of its components, can effectively straighten products before or during semiconductor component processing, ensuring the straightness of the products and thus improving processing accuracy. The mechanism can adapt to the straightening requirements of products of different lengths, making it highly adaptable. The components are firmly connected, easy to operate, and improve processing efficiency, meeting the semiconductor industry's requirements for high-precision component processing.
[0012] The connecting rod provides the main support for the entire mechanism and is the foundation for connecting all components. The positioning block is used to position semiconductor components, ensuring the product is in the correct position during straightening. The slide bar cooperates with the positioning block, allowing the positioning block to slide along the slide bar, thus adapting to the straightening needs of parts of different lengths and increasing the applicability of the mechanism. The limit block limits the range of the positioning block's sliding along the slide bar, preventing components from sliding excessively and detaching from the slide bar. The set screw is used to fix relevant components in the appropriate position, ensuring the stability of each component's position during operation. The positioning pin cooperates with the positioning block to achieve precise positioning of the product parts, further ensuring straightening accuracy and giving the product good straightness after processing. The guide sleeve is fitted on the outside of relevant components, providing guidance for the movement of the components, reducing friction during movement, making sliding and other operations smoother, and also providing a certain degree of protection for the components.
