[0001] The present invention relates to a fixing device, in particular to a screw-on and snap-on device capable of performing screwing and snapping simultaneously. Background Art

[0002] Chip testing is a crucial component of the semiconductor industry. To meet increasingly sophisticated chip specifications, the development of test equipment and related components is crucial. Current test equipment uses a fixture to press the chip under test into a test socket, ensuring it is positioned correctly for testing. Testing is often performed with the assistance of a robotic arm, minimizing human interaction and improving test accuracy.

[0003] Please refer to Figure 6 , Figure 6 The figure is a three-dimensional operating diagram of a conventional fixing device 900. Conventional fixing device 900 comprises an upper cover 910, a middle base 920, and a base 930. Middle base 920 comprises a latch 921. To open the upper cover 910 of conventional fixing device 900, one must first unscrew the upper cover 910 and then pull the latch 921 open to fully open the device. To close the upper cover 910, one must first engage the latch 921 and then tighten the upper cover 910. As can be seen, the operation of conventional fixing device 900 is quite cumbersome, and whether performed manually or by robotic means, both require a certain amount of time and maintenance costs.

[0004] Therefore, it is necessary to provide a screw-on buckle device to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a screw-on snap-fit ​​device that can simultaneously complete screwing and snap-fitting states in a single action.

[0006] One embodiment of the present invention provides a screw-on snap-fit ​​device, which includes a base, a middle seat and an upper cover. The middle seat is detachably snap-fitted to the base, and includes a main body, two snap-fits and two elastic components. The two snap-fits are respectively arranged on the two sides of the main body, and each snap-fit ​​is pivotally connected to the main body via a rotating shaft. Each elastic component abuts each snap-fit ​​against the main body. The upper cover is screwed onto the middle seat, and includes an abutting portion abutting the two snap-fits, and the abutting portion includes two guide grooves. When the upper cover rotates, at least a portion of the two snap-fits enters or exits the two guide grooves. The two elastic components are closer to the base than the two rotating shafts. When the upper cover is screwed onto the middle seat, the abutting portion pushes the two snap-fits to pivot and snap-fit ​​the base, and when the upper cover and the middle seat are loosened, the two elastic components push the two snap-fits to pivot and separate from the base.

[0007] Accordingly, the screw-on buckle device of the present invention pushes the buckle to pivot through the abutment portion or elastic component, and can complete actions such as tightening the upper cover and fixing the buckle in one step, and can also complete actions such as opening the upper cover and releasing the buckle in one step. Therefore, it can reduce the complexity of the robot arm operation, making the overall testing process more simplified, thereby improving testing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following describes various embodiments of the present invention in greater detail. However, these embodiments may encompass a wide variety of inventive concepts and may be implemented within a variety of specific scopes. The specific embodiments described are for illustrative purposes only and are not intended to limit the scope of the present disclosure. Furthermore, to simplify the drawings, some commonly used structures and components are depicted in simplified schematic form.

[0048] Please refer to Figure 1 and Figure 2 , Figure 1FIG1 is a perspective diagram of a screw-on buckle device 100 in an unscrewed state according to an embodiment of the present invention. Figure 2 for Figure 1 1 is an exploded view of a screw-on buckle device 100. The screw-on buckle device 100 includes a base 110, a middle base 120, and a top cover 130. The middle base 120 is detachably engaged with the base 110, and the top cover 130 is screwed onto the middle base 120.

[0049] Specifically, the center base 120 includes a main body 121, two latches 122, and two elastic components 123. The two latches 122 are respectively disposed on two sides of the main body 121, and each latch 122 is pivotally connected to the main body 121 via a rotating shaft 124, while each elastic component 123 abuts against each latch 122 and the main body 121. Thus, each latch 122 can pivot relative to the main body 121, and each elastic component 123 can push each latch 122 to reset. For example, the two latches 122 can be disposed on opposite sides of the main body 121 to enhance the stability of the center base 120 when engaging the base 110. However, the actual position of the latches 122 can be determined according to the desired use, and therefore the present invention is not limited to the position of the latches 122.

[0050] Each elastic component 123 may include three springs (not separately labeled), and the three springs may be arranged in sequence along an extension direction of each rotating shaft 124, and each spring may respectively abut against each buckle 122 and the body 121, thereby more stably pushing each buckle 122 to reset. However, the present invention is not limited to the type or number of the above-mentioned elastic components 123.

[0051] The upper cover 130 includes an abutting portion 131 abutting against the two buckles 122 , and the abutting portion 131 includes two guide grooves 132 . When the upper cover 130 rotates, at least a portion of the two buckles 122 enters or exits the two guide grooves 132 .

[0052] Please refer to Figures 3A to 3C and Figure 4 , Figure 3A for Figure 1 A partial cross-sectional diagram of the screw-on buckle device 100, Figure 3B for Figure 1 A partial cross-sectional diagram of the screw-on snap-fit ​​device 100 in a partially screwed-on state, Figure 3C for Figure 1 A partial cross-sectional diagram of the screw-on snap-fit ​​device 100 in a fully screwed-on state, Figure 4 for Figure 1Schematic diagram of the screw-on snap-in device 100 in a fully screwed-on state. The two elastic components 123 are closer to the base 110 than the two rotating shafts 124. When the upper cover 130 is screwed onto the middle base 120, the two snaps 122 exit the two guide grooves 132. At this time, the abutment portion 131 pushes the two snaps 122 to pivot and engage with the base 110. When the upper cover 130 and the middle base 120 are loosened, the two snaps 122 enter the two guide grooves 132. At this time, the two elastic components 123 push the two snaps 122 to pivot and separate from the base 110. In this way, the snaps 122 can be pivoted and engaged or separated from the base 110 when the upper cover 130 is rotated. Therefore, the upper cover 130 and the fixed base 110 can be locked or the upper cover 130 can be loosened and the base 110 can be separated in a single action, thereby greatly reducing the complexity of operation and improving efficiency.

[0053] Furthermore, the abutment portion 131 or the two elastic elements 123 can push the two latches 122 to pivot at an angle A, which can be between 3.8 and 30.0 degrees. Each latch 122 can have a hook portion 125, located at one end of the latch 122 adjacent to the base 110. The base 110 can have two engaging portions 111. When the upper cover 130 is fully screwed onto the middle base 120, each hook portion 125 can engage with a respective engaging portion 111. This enhances the stability of the latch 122 when engaged with the base 110.

[0054] Please refer to Figure 5A and Figure 5B , Figure 5A for Figure 1 A side view of the upper cover 130 of the screw-on snap-fit ​​device 100, Figure 5B for Figure 1 Schematic diagram of the upper cover 130 of the screw-on buckle device 100. For example, the abutting portion 131 may have an edge E, the edge E and the two buckles 122 may abut against each other, and the two guide grooves 132 may be recessed in the edge E. The edge E may be a lower edge of the abutting portion 131 adjacent to the buckles 122, and each guide groove 132 may be recessed in the edge E and generally present an inverted L-shape, so when the upper cover 130 rotates, one end of each buckle 122 adjacent to the upper cover 130 may at least partially enter or exit the corresponding guide groove 132. The shape of the end of each buckle 122 adjacent to the upper cover 130 and the shape of each guide groove 132 may match each other, or a depth D of each guide groove 132 may be 0.6 mm to 5.0 mm (e.g. Figure 3C ), so as to improve the stability of the buckle 122 when it contacts and stays in the guide groove 132.

[0055] Each guide groove 132 may have at least one guide portion 133 and a positioning portion 134. The guide portion 133 may connect to the positioning portion 134, and when the upper cover 130 rotates, the two latches 122 may enter or exit the positioning portion 134 through the guide portion 133. The guide portion 133 may generally be an inclined surface, connecting the portion of the abutment portion 131 not provided with the guide groove 132 and the positioning portion 134, respectively, to serve as a transition structure between the abutment portion 131 and the positioning portion 134, allowing the two latches 122 to enter or exit the positioning portion 134 more smoothly.

[0056] Furthermore, each buckle 122 may have a buffer portion 126, and the buffer portion 126 may abut against the abutting portion 131 or the guide groove 132. Figure 5B As shown, the guide portion 133 can be a gently sloped surface with an arc to reduce collision when the clip 122 enters or exits the positioning portion 134, thereby reducing wear of the clip 122. The number of guide portions 133 in each guide slot 132 can be two, and the positioning portion 134 can be located between the two guide portions 133, so that when the upper cover 130 rotates clockwise or counterclockwise, both clips 122 can smoothly enter or exit the positioning portion 134.

[0057] The body 121 may include a latch 127, and the abutment portion 131 may further include a guide rail 135. The latch 127 is movably received within the guide rail 135, and when the upper cover 130 rotates, the latch 127 can move relative to the guide rail 135. This improves the stability of the upper cover 130 during rotation. For example, the abutment portion 131 may be annular, and the guide rail 135 may be recessed in a bottom surface of the abutment portion 131. The guide rail 135 may extend from one side of the abutment portion 131 to a side opposite the one side, so that the shape of the guide rail 135 is generally C-shaped. When the upper cover 130 rotates, the upper cover 130 can rotate at an angle of 0 to 180 degrees. Thus, the annular abutting portion 131 can reduce vibration or collision when the buckle 122 is pushed. It should be noted that the extension range of the guide rail 135 can be determined according to the rotation angle of the upper cover 130 to meet the usage requirements in different scenarios.

[0058] The center base 120 may further include a lifting element 128. The body 121 may surround the lifting element 128. The upper cover 130 may further include a screw-on portion 136. The screw-on portion 136 may be connected to the abutting portion 131 and screwed onto the body 121. A bottom surface of the screw-on portion 136 may abut the lifting element 128. When the upper cover 130 is screwed onto the center base 120, the screw-on portion 136 may push the lifting element 128 to move. In this manner, an object under test can be placed between the lifting element 128 and the base 110. When the upper cover 130 is fully screwed onto the center base 120, the lifting element 128 and the base 110 can jointly clamp the object under test to prevent displacement of the object under test.

[0059] The upper cover 130 may further include a rolling element 137. The rolling element 137 may be embedded in the bottom surface of the screw-on portion 136. When the screw-on portion 136 pushes the lifting element 128 to move, the rolling element 137 may abut against the lifting element 128 and roll, thereby reducing friction between the bottom surface of the screw-on portion 136 and the lifting element 128. For example, the bottom surface of the screw-on portion 136 may be recessed with a rolling element groove. The rolling element groove may be annularly arranged along the circumference of the screw-on portion 136, and the rolling element 137 may be received in the rolling element groove so that the rolling element 137 can roll along the rolling element groove. Alternatively, the bottom surface of the screw-on portion 136 may be recessed with a rolling element hole for receiving the rolling element 137. When the upper cover 130 is screwed onto the middle seat 120, the rolling element 137 may be pushed by the lifting element 128 and rotate within the rolling element hole. Therefore, the present invention is not limited to the above arrangement.

[0060] In summary, the screw-on buckle device of the present invention pushes the buckle to pivot through the abutment portion or elastic component, and can complete actions such as tightening the upper cover and fixing the buckle in one step, and can also complete actions such as opening the upper cover and releasing the buckle in one step. Therefore, it can reduce the complexity of the robot arm operation, making the overall testing process more simplified, thereby improving testing efficiency.

[0061] Although the present invention has been disclosed above with reference to the embodiments, they are not intended to limit the present invention. Any person skilled in the art should be able to make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the appended claims.
