[0002] In the wafer manufacturing process, defects may occur on the wafer surface, and in order to prevent the wafer with defects from flowing into the packaging process, the wafer needs to be detected. A common detection method includes a needle contact method, which detects through the contact between a probe and the wafer surface.

[0003] The probe card provided with the probe is installed on a needle card tray, the needle card tray is installed on a turnover frame, and the turnover frame is connected with the supporting rod assembly and a turnover driving member. The supporting rod assembly comprises a sliding base and a sliding rod. When the turnover driving member pulls down the turnover frame, the sliding rod slides out relative to the sliding base and is limited by a limiting groove on the sliding base. At this time, the sliding rod bears most of the gravity of the turnover frame and the needle card tray. However, the limiting groove on the sliding base is relatively weak, and after being used for a period of time, the limiting groove at the position is prone to deformation and damage due to extrusion, resulting in the problems of jamming of the sliding rod, turnover jamming, inclination of the needle card tray, unevenness of the supporting surface of the needle card tray supporting the probe card, and difficulty in card replacement.

[0049] Referring to Figures 1 to 4 , and Figure 6 , in a first aspect, the present application provides a support rod assembly 100, which comprises a sliding base 10 and a sliding unit 20. The sliding base 10 comprises a main body 11 and a partition protrusion 12. The main body 11 has a sliding groove therein. The partition protrusion 12 is arranged in the sliding groove and divides the sliding groove into a first sliding groove 13 and a second sliding groove 14 arranged along the width direction Y of the main body 11. The first sliding groove 13 and the second sliding groove 14 are in communication with each other. The partition protrusion 12 has a first surface 121 arranged along the length direction X of the main body 11. The first surface 121 and the groove side wall of the sliding groove define a first transition section 15 at the start of the first sliding groove 13 and the end of the second sliding groove 14. The first surface 121 is recessed to form a limiting groove 123. The sliding unit 20 has a guide sliding part 221 which extends into the sliding groove and can slide along the side wall of the sliding groove.

[0050] The support rod assembly 100 has a first state and a second state. Specifically, the sliding unit 20 can slide out relative to the sliding base 10 along the length direction X of the main body 11 to the first state. When the sliding unit 20 is in the first state, the guide sliding part 221 is located in the first transition section 15 and is limited in the limiting groove 123. The sliding unit 20 can also slide in relative to the sliding base 10 along the length direction of the main body 11 to retract to the second state. When the sliding unit 20 is in the second state, the guide sliding part 221 is located at the start of the second sliding groove 14.

[0051] It can be understood that the sliding base 10 mainly plays a supporting, guiding and mounting role. It can be made of sheet metal, plastic or other materials with good mechanical strength. The sliding base 10 comprises the main body 11 and the partition protrusion 12. The main body 11 and the partition protrusion 12 are integrally processed and formed to increase the strength of the sliding base 10.

[0052] The main body 11 is provided with a sliding groove. The partition protrusion 12 is located in the sliding groove and protrudes from the groove bottom wall. The partition protrusion 12 is spaced apart from the groove side wall of the sliding groove. The partition protrusion 12 divides the sliding groove into the first sliding groove 13 and the second sliding groove 14 which are in communication with each other. The first sliding groove 13 and the second sliding groove 14 are arranged along the width direction Y of the main body 11.

[0053] The start of the first sliding groove 13 (such as the first transition section 15) and the end of the second sliding groove 14 (such as the second transition section 16) are arranged along the length direction X of the main body 11. Figure 4Position A in the diagram indicates the position where the guide slide 221 enters the first slide groove 13, and the termination position of the second slide groove 14 (as shown in Figure A). Figure 4 Position D in the diagram indicates the position where the guide slide 221 moves out of the second slide groove 14. After the guide slide 221 moves out from the end position of the second slide groove 14, it enters the starting position of the first slide groove 13 via the first transition section 15.

[0054] When the sliding unit 20 is in the first state, it extends relative to the slide block 10, making the overall length of the support rod assembly 100 longer to facilitate support. At this time, the guide slide 221 is located in the first transition section 15 and confined within the limiting groove 123 to achieve effective support. Thus, by utilizing the protruding and recessed surface design to form the limiting groove 123 to achieve the purpose of limiting the guide slide 221, its structural strength is greater, it is less susceptible to damage from compression, has a lower risk of jamming, and a longer service life.

[0055] In some embodiments, the separating protrusion 12 has a second surface 122 opposite to the first surface 121 along the length direction X of the body 11. The second surface 122 and the groove sidewall define a second transition section 16 that connects the end position of the first groove 13 and the beginning position of the second groove 14. The sliding unit 20 can retract to a second state relative to the slide block 10 along the length direction of the body 11. When the sliding unit 20 is in the second state, the guide slide 221 is limited to the beginning position of the second groove 14. When the guide slide 221 circulates within the first transition section 15, the first groove 13, the second transition section 16, and the second groove 14, the strut assembly 100 switches between the first state and the second state. By limiting the guide slide 221 with the beginning position of the second groove 14, the strut assembly 100 is maintained in the second state to facilitate the storage of the strut assembly 100.

[0056] The end position of the first slide 13 (e.g.) Figure 4 Position B in the diagram indicates the position where the guide slide 221 moves out of the first slide groove 13, and the starting position of the second slide groove 14 (as shown in Figure B). Figure 4 Position C indicates the position where the guide slide 221 enters the second slide groove 14. After the guide slide 221 is displaced from the end position of the first slide groove, it enters the starting position of the second slide groove 14 via the second transition section 16.

[0057] When the strut assembly 100 is in the second state, the sliding unit 20 retracts relative to the slide block 10 along the length direction of the main body 11, and the overall length of the strut assembly 100 is relatively short.

[0058] In actual operation, when the support rod assembly 100 is in the second state, the guide sliding part 221 is located at the starting position of the second sliding groove 14. Under the driving of an external force, the sliding unit 20 moves the guide sliding part 221 from the starting position of the second sliding groove 14 to the ending position of the second sliding groove 14, and further to the first transition section 15, and limits the guide sliding part 221 in the limiting groove 123. At this time, the support rod assembly 100 is switched from the second state to the first state, and the length of the support rod assembly 100 is relatively long. Similarly, the guide sliding part 221 can move to the starting position of the first sliding groove 13 through the first transition section 15, and further move to the ending position of the first sliding groove 13 away from the side wall of the second sliding groove 14, and move to the starting position of the second sliding groove 14 through the second transition section 16. At this time, the support rod assembly 100 is switched from the first state to the second state.

[0059] Referring to Figures 2 to 6 In some embodiments, the sliding unit 20 includes a sliding rod 21 and a guide sliding block 22. The guide sliding block 22 includes a connecting part 222 and a guide sliding part 221. The connecting part 222 and the sliding rod 21 are both located outside the sliding groove, and the connecting part 222 is rotationally connected with the sliding rod 21. The guide sliding part 221 is arranged on the connecting part 222 and at least partially extends into the sliding groove. The sliding rod 21 can slide out to the first state along the length direction of the main body 11 relative to the sliding base 10, or retract to the second state along the length direction of the main body 11. When the support rod assembly 100 is in the first state, the sliding rod 21 extends relative to the sliding base 10. When the support rod assembly 100 is in the second state, the sliding rod 21 retracts relative to the sliding base 10. It can be understood that when an external force acts on the sliding rod 21, the sliding rod 21 can drive the guide sliding part 221 to cyclically move along the length direction of the main body 11 relative to the sliding base 10, so that the support rod assembly 100 is switched between the first state and the second state.

[0060] The opposite two sides of the connecting part 222 arranged along the thickness direction Z of the main body 11 are respectively provided with the sliding rod 21 and the guide sliding part 221. One end of the connecting part 222 is rotationally connected with the sliding rod 21, and the other end of the connecting part 222 is fixedly connected with the guide sliding part 221. Specifically, the guide sliding part 221 and the connecting part 222 can be integrally formed, or can be separately arranged and fixedly connected through welding, clamping or the like.

[0061] In actual operation, the sliding rod 21 drives the connecting part 222 and the guide sliding part 221 to move along the length direction of the main body 11 under the action of an external force, and at the same time, the connecting part 222 rotates relative to the sliding rod 21, so that the guide sliding part 221 can move and switch positions in the first transition section 15, the first sliding groove 13, the second transition section 16 and the second sliding groove 14, thereby promoting the sliding rod 21 to slide along the length direction X of the main body 11, and realizing the extension and retraction operation of the sliding rod 21 relative to the sliding base 10.

[0062] The connecting part 222 connects the slide rod 21 and the guide slide part 221, and is rotatably connected to the slide rod 21, so as to drive the guide slide part 221 to flexibly turn and change position in the first transition section 15, the first slide groove 13, the second transition section 16 and the second slide groove 14, thereby reducing the occurrence of jamming.

[0063] In some embodiments, the second transition section 16 has a transition opening 161 communicating with the second slide groove 14, and the support rod assembly 100 further comprises an opening and closing part 30 for opening and closing the transition opening 161. One end of the opening and closing part 30 is arranged on the partition protrusion 12, and the other end extends along the length direction of the main body 11 into the second slide groove 14 and abuts against the groove wall of the second slide groove 14 close to the first slide groove 13. The opening and closing part 30 is used to open the transition opening 161 during the movement of the guide slide part 221 from the second transition section 16 into the second slide groove 14, and to close the transition opening 161 when the guide slide part 221 moves in the second slide groove 14.

[0064] For example, the opening and closing part 30 closes the transition opening 161 when the guide slide part 221 moves in the second slide groove 14, the first transition section 15 and the first slide groove 13, that is, the opening and closing part 30 is in an open state only when the guide slide part 221 moves from the second transition section 16 into the second slide groove 14.

[0065] When the opening and closing part 30 opens the transition opening 161, the guide slide part 221 can smoothly enter the second guide slide groove from the second transition section 16 through the transition opening 161, so as to switch to the second state. When the opening and closing part 30 closes the transition opening 161, the opening and closing part 30 separates the second slide groove 14 from the second transition section 16. Thus, when the support rod assembly 100 switches from the second state to the first state, and the guide slide part 221 slides from the starting position of the second slide groove 14 to the ending position of the second slide groove 14, the guide slide part 221 will not enter the second transition section 16 and the first slide groove 13 from the transition opening 161, which ensures the normal switching of the states and improves the reliability of the state switching of the support rod assembly 100, and has a high state switching efficiency.

[0066] Please refer to Figures 4 to 6 Further, in some embodiments, the opening and closing part 30 is a resilient sheet. The resilient sheet can open the transition opening 161 by being pressed by the guide slide part 221, and can close the transition opening 161 by rebounding under the action of its own resilience when the guide slide part 221 is separated from the resilient sheet.

[0067] In actual operation, when the guide sliding part 221 is moved into the second sliding groove 14 from the second transition section 16, the guide sliding part 221 pushes the elastic sheet and pushes the elastic sheet away, and the transition opening 161 is opened. At this time, the elastic sheet is deformed and stores elastic potential energy. After the guide sliding part 221 is separated from the elastic sheet, the pushing force of the guide sliding part 221 on the elastic sheet disappears, the elastic sheet releases the elastic potential energy and rebounds to close the transition opening 161 again. It can be understood that by arranging the elastic sheet, the elastic sheet can automatically open and close the transition opening 161, which is simple and easy to operate, and has a long service life.

[0068] Of course, the opening and closing member 30 can open the transition opening 161 in the manner of the elastic sheet, but not limited to the manner of the elastic sheet, and can also open the transition opening 161 by means of a driving structure.

[0069] Please refer to Figures 4 to 5 In some embodiments, the elastic sheet has a hooking part 31 and an opening and closing part 32, the hooking part 31 is hooked on the separation protrusion 12, and the opening and closing part 32 is arranged along the length direction of the main body 11 and is used to open and close the transition opening 161.

[0070] Specifically, as Figure 5 shown, the separation protrusion 12 includes a first part 124 and a second part 125, the first surface 121 is located on the first part 124, the second surface 122 is formed by the two surfaces of the first part 124 and the second part 125 away from the first surface 121, and the first part 124 and the second part 125 are arranged at intervals and form a hooking gap 126. The hooking gap 126 includes a first section 1261 and a second section 1262 which are communicated with each other, the first section 1261 extends along the width direction Y of the main body 11 and communicates with the second sliding groove 14, and the second section 1262 extends along the length direction X of the main body 11 and communicates with the second transition section 16. The opening and closing part 32 of the hooking part 31 extends into the second sliding groove 14 along the length direction of the main body 11 and abuts against the groove wall of the second sliding groove 14 close to the second transition section 16, and the hooking part 31 is bent into the second section 1262 through the first section 1261 to realize hooking.

[0071] By means of hooking, it is not necessary to arrange additional fasteners to connect and fix the elastic sheet and the separation protrusion 12, and the installation is simple and convenient. Moreover, this kind of way does not occupy too much space in the sliding groove, and can ensure the smoothness of the guide sliding part 221 sliding in the sliding groove and reduce the occurrence of jamming.

[0072] Of course, the installation mode of the elastic sheet is not limited to the hooking mode, and can also be a buckling mode, a welding mode or other modes.

[0073] Please refer to Figure 2 , Figure 4 and Figure 6In some embodiments, the guide slider 22 further includes a shaft portion 223, and the connecting portion 222 is rotatably connected to the slide rod 21 through the shaft portion 223; the sliding unit 20 further includes a torsion spring 23, which is sleeved on the shaft portion 223, and the two opposite ends of the torsion spring 23 are respectively connected to the guide slider 22 and the slide rod 21.

[0074] The shaft portion 223 and the connecting portion 222 are integrally formed.

[0075] The torsion spring 23 ensures that the guide slider 22 is always subjected to clockwise or counterclockwise torque. This forces the guide slider 221 to slide along the side wall of the groove, the surface of the dividing protrusion 12, or the surface of the opening and closing member 30 during the sliding process. This achieves the guidance and sliding of the guide slider 221, reduces the risk of shaking during the sliding process, improves the smoothness of the sliding of the guide slider 221, and minimizes the risk of jamming.

[0076] by Figure 4 Taking the state of the middle strut assembly 100 and the torque of the torsion spring 23 forcing the guide slider 22 to always have a clockwise (as indicated by arrow W) rotation torque as an example, during the sliding process of the guide slider 221 in the first slide groove 13, the guide slider 221 slides along the groove side wall of the first slide groove 13 that is opposite to the partition protrusion 12. During the sliding process of the guide slider 221 in the second slide groove 14, the guide slider 221 slides along the groove side wall of the second slide groove 14 on the side where the partition protrusion 12 is located.

[0077] Please see Figure 2 and Figure 3 In some embodiments, the slide block 10 is provided with a mounting groove 17. The mounting groove 17 and the slide groove are arranged sequentially and connected along the thickness direction Z of the main body 11. The slide rod 21 and the connecting part 222 are both located in the mounting groove 17.

[0078] Specifically, the main body 11 includes a base plate 18 and two side plates 19.
