Description

Technical Field

[0001] This utility model relates to the field of chip manufacturing technology, and specifically to a quick-release ejector pin. Background Technology

[0002] In chip manufacturing at semiconductor DB sites, ejector pins are core components that ensure chip mounting accuracy and production efficiency. Existing technologies, traditional ejector pins have the following drawbacks: their heads are fixed in one piece, requiring the ejector pin base to be removed before replacing with different sized pins. Furthermore, the connection between the ejector pin and the equipment must be manually tightened, making the process cumbersome and prone to damaging other components due to frequent disassembly, thus increasing equipment maintenance costs. Simultaneously, the calibration and adjustment of the ejector pin's center hole is complex and time-consuming, directly increasing equipment downtime. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0020] Example 1

[0021] A quick-release ejector pin includes: a base 1 and a positioning seat 2. The base 1 has a threaded connection part 11 at its lower end and a positioning groove 12 and a locking groove 13 symmetrically arranged at its upper end. The positioning seat 2 has an ejector pin hole 21 at its upper end and a positioning pin 22 and a locking module 23 symmetrically arranged at its lower end. The positioning pin 22 is correspondingly arranged with the positioning groove 12. The locking module 23 includes a mounting seat 231 and a locking pin 232. The mounting seat 231 is disposed on the side wall of the positioning seat 2. The locking pin 232 is hinged to the mounting seat 231 by a torsion spring and its lower end is correspondingly arranged with the locking groove 13. A magnetic suction element 14 is embedded in the upper end of the base 1, and a magnetic suction element 24 is disposed in the lower end of the positioning seat 2. The magnetic suction element 14 and the magnetic suction element 24 are correspondingly arranged.

[0022] like Figures 1-4 As shown, during installation, the base 1 is first fixed to the device pin base via the threaded connection 11 of the base 1. Then, the positioning seat 2 is held so that the lower positioning pin 22 aligns with the positioning groove 12 of the base 1. Under magnetic attraction, the positioning pin 22 quickly embeds into the positioning groove 12, achieving initial positioning. Next, the positioning seat 2 is gently pressed, and the locking pin 232 rotates around the hinge point under the force of the torsion spring, its lower end naturally locking into the locking groove 13, thus locking the positioning seat 2 to the base 1. During disassembly, the upper end of the locking pin 232 is first moved with a finger to overcome the torsion spring force and disengage the lower end from the locking groove 13. Then, the positioning seat 2 is lifted upwards, and the positioning pin 22 disengages from the magnetic attraction of the positioning groove 12 under pulling force, allowing the positioning seat 2 to be removed from the base 1.

[0023] When it is necessary to replace the ejector pins of different sizes, this utility model only requires disassembling the positioning seat 2, replacing it with a positioning seat with the corresponding ejector pin hole 21, and then reassembling. Through the cooperation of the positioning groove 12 and the positioning pin 22 and the magnetic attraction, the coaxiality requirement between the ejector pin hole 21 and the center hole of the equipment is met, eliminating the tedious steps of traditional manual calibration.

[0024] In addition, the positioning seat 2 adopts a split design. After disassembly, the pin hole 21 and the inner wall of the positioning seat can be cleaned directly (removing debris and impurities), which avoids impurities from affecting the vacuum adsorption performance of the pin, extends the service life of the pin, and reduces the frequency of hand reaching into the bottom of the equipment during operation, thus improving operational safety.

[0025] As a further preferred embodiment, an adjusting plate 2321 is fixedly provided on the upper end of the locking pin 232.

[0026] Specifically, when it is necessary to disassemble the positioning seat 2, the operator can directly pinch the adjusting plate 2321 and pull it upwards, which can overcome the torsion spring force without the need for tools, so that the lower end of the locking pin 232 disengages from the locking groove 13. Compared with directly pulling the locking pin 232, the adjusting plate 2321 increases the operating contact area and avoids direct friction between the hand and the metal parts.

[0027] As a further preferred embodiment, the upper end of the positioning seat 2 is provided with a gripping groove 25, and the gripping groove 25 is arranged in a circular array of at least two sets.

[0028] Specifically, when replacing the positioning seat 2, the operator can insert their thumb and forefinger into the symmetrical gripping groove 25, and use the groove to position and hold the positioning seat 2 stably, avoiding misalignment between the positioning pin 22 and the positioning groove 12 due to hand slippage.

[0029] Furthermore, the grip groove 25 is provided with anti-slip texture to prevent slipping during installation.

[0030] As a further preferred embodiment, the outer side of the base 1 is provided with grooves.

[0031] Specifically, when the base 1 is fixed to the equipment through the threaded connection part 11, the operator can increase the friction between the hand and the base 1 by using the grooves, and manually tighten the base 1 without using a wrench, thus avoiding scratches on the surface of the base 1 caused by tool contact.

[0032] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
