[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Figure 1A probe device 100 is shown, comprising a needle seat 110 and a probe 120 disposed on the needle seat 110, wherein the needle seat 110 is used to mount the probe 120 and can drive the tip of the probe 120 to move. The needle seat 110 comprises a guide rail 111, a sensor 112 slidably disposed on the guide rail 111, and a probe mounting member 113 connected to the sensor 112, and the probe 120 is disposed on the probe mounting member 113. The sensor 112 is a pressure sensor, which is used to detect the pressure on the probe 120, thereby detecting the pressure between the probe 120 and the object to be detected.

[0036] In some embodiments, the object to be detected is an LED chip. After the probe 120 contacts the solder joint of the LED chip, it can apply an electrical signal to the LED chip to detect the performance of the LED chip.

[0037] like Figure 2 As shown, a needle seat positioning disk 200 provided in the present application includes an arc-shaped assembly portion 210 and a connecting portion 220 .

[0038] The arc-shaped assembly portion 210 is arc-shaped, and two ends of the connecting portion 220 are respectively connected to two ends of the arc-shaped assembly portion 210 . The arc-shaped assembly portion 210 and the connecting portion 220 are surrounded to form an avoidance space 200 a .

[0039] Specifically, the connecting portion 220 is located inside the arc-shaped assembly portion 210 , and the connecting portion 220 connects two ends of the arc-shaped assembly portion 210 , thereby enhancing the strength of the entire needle seat positioning disk 200 , and the arc-shaped assembly portion 210 and the connecting portion 220 are surrounded to form an avoidance space 200 a .

[0040] The inner wall of the arc-shaped assembly portion 210 is connected to a plurality of first positioning portions 240 located in the avoidance space 200a. The plurality of first positioning portions 240 are arranged at intervals along the arc length direction of the arc-shaped assembly portion 210, and a first positioning groove 240a is formed between each two adjacent first positioning portions 240.

[0041] The connecting portion 220 is connected to a supporting portion 230 located in the avoidance space 200a on one side of the inner wall close to the arc-shaped assembly portion 210. A plurality of second positioning portions 250 are arranged on the upper surface of the supporting portion 230. The plurality of second positioning portions 250 are arranged at intervals along the arc length direction of the arc-shaped assembly portion 210, and a second positioning groove 250a is formed between each two adjacent second positioning portions 250.

[0042] like Figures 3 to 5As shown, it can be understood that the needle seat 110 is used to be arranged on the arc-shaped assembly part 210, and when the needle seat 110 is arranged on the arc-shaped assembly part 210, the sensor 112 is limited to the first positioning groove 240a between the two adjacent first positioning parts 240, and the probe mounting part 113 is limited to the second positioning groove 250a between the two adjacent second positioning parts 250. Among them, the first positioning groove 240a can play a positioning role for the sensor 112, and the second positioning groove 250a can play a positioning role for the probe mounting part 113, thereby improving the positioning effect of the probe 120. At the same time, by arranging the positioning structure on the needle seat positioning disk 200, it is not necessary to add a corresponding positioning structure on the needle seat 110, which can reduce the manufacturing and processing difficulty and cost of the needle seat 110.

[0043] It should be noted that the positioning of the sensor 112 by the first positioning groove 240a may refer to the two side walls of the first positioning groove 240a contacting the sensor 112 to achieve the positioning of the sensor 112; the positioning of the probe mounting member 113 by the second positioning groove 250a may refer to the two side walls of the second positioning groove 250a contacting the probe mounting member 113 to achieve the positioning of the probe mounting member 113.

[0044] The needle seat positioning disk 200 of the present application can realize the installation of multiple probe devices 100. Under the joint action of multiple first positioning parts 240 and multiple second positioning parts 250, multiple probe devices 100 can be positioned, thereby ensuring the positioning effect of the needle tips of all probes 120, so that the needle tips of all probes 120 are arranged in an orderly manner.

[0045] Furthermore, a avoidance hole 231 is also provided on the support portion 230 , and the arc structure formed by the cooperation of the plurality of second positioning portions 250 is coaxially arranged with the avoidance hole 231 .

[0046] It can be understood that the multiple second positioning portions 250 are arranged at intervals along the arc length direction of the arc-shaped assembly portion 210. Therefore, the multiple second positioning portions 250 are arranged to form an arc structure, which is coaxially arranged with the avoidance hole 231. In this way, the needle tip of the probe 120 can contact the object to be detected located below the support portion 230 through the avoidance hole 231.

[0047] It should be noted that in the needle seat positioning disk 200 of the present application, the plurality of first positioning portions 240 are evenly and spaced apart along the arc length direction of the arc-shaped assembly portion 210, and the plurality of second positioning portions 250 are evenly and spaced apart along the arc length direction of the arc-shaped assembly portion 210. In this way, all needle seats 110 disposed on the needle seat positioning disk 200 can be arranged evenly and orderly, and further, the needle tips of all probes 120 can be arranged orderly.

[0048] Furthermore, the plurality of first positioning grooves 240a correspond one to one with the plurality of second positioning grooves 250a.

[0049] Specifically, the number of the first positioning grooves 240a is the same as the number of the second positioning grooves 250a, and the projections of the plurality of first positioning grooves 240a on the horizontal plane are opposite to the projections of the plurality of second positioning grooves 250a on the horizontal plane.

[0050] In some embodiments, the needle seat positioning disk 200 is an integrally formed structure. That is, the arc-shaped assembly portion 210, the connecting portion 220, the supporting portion 230, the first positioning portion 240 and the second positioning portion 250 are an integral structure. In this way, assembly errors caused by different parts can be avoided, and the positioning effect of the needle seat 110 can be further improved.

[0051] Of course, in other embodiments, the arc-shaped assembly portion 210 , the connecting portion 220 , the supporting portion 230 , the first positioning portion 240 and the second positioning portion 250 may also be different components, which are assembled with each other to form the needle seat positioning disk 200 .

[0052] like Figure 2 As shown, further, the two side walls of the first positioning groove 240a oppositely arranged along the arc length direction of the arc-shaped assembly portion 210 are plane walls, that is, the two side walls of the first positioning portion 240 oppositely arranged along the arc length direction of the arc-shaped assembly portion 210 are plane walls.

[0053] like Figure 4 As shown, it can be understood that the left and right side walls of the sensor 112 are plane walls. After the sensor 112 is inserted into the first positioning groove 240a, the left and right side walls of the sensor 112 are respectively opposite to the two side walls of the first positioning groove 240a. In this way, under the action of the two side walls of the first positioning groove 240a, the positioning of the sensor 112 can be achieved.

[0054] like Figure 5 As shown, further, the two side walls of the second positioning groove 250a oppositely arranged along the arc length direction of the arc-shaped assembly portion 210 are plane walls, that is, the two side walls of the second positioning portion 250 oppositely arranged along the arc length direction of the arc-shaped assembly portion 210 are plane walls.

[0055] It can be understood that the left and right side walls of the probe mounting component 113 are plane walls. After the probe mounting component 113 is inserted into the second positioning groove 250a, the left and right side walls of the probe mounting component 113 are respectively opposite to the two side walls of the second positioning groove 250a. In this way, under the action of the two side walls of the second positioning groove 250a, the positioning of the probe mounting component 113 can be achieved.

[0056] like Figure 2As shown, in some embodiments, the distance between the two side walls of the first positioning portion 240 that are arranged opposite to each other along the arc length direction of the arc-shaped assembly portion 210 gradually decreases along a preset direction, wherein the preset direction is parallel to the radial direction of the arc-shaped assembly portion 210, and the preset direction points from the outer diameter of the arc-shaped assembly portion 210 to the inner diameter of the arc-shaped assembly portion 210.

[0057] It can be understood that since the inner wall of the arc-shaped assembly portion 210 is an arc surface, and by gradually reducing the distance between the two side walls of the first positioning portion 240 that are arranged opposite to each other along the arc length direction of the arc-shaped assembly portion 210 along the preset direction, the width of the first positioning groove 240a can be made basically consistent in the preset direction, thereby ensuring the positioning effect of the sensor 112.

[0058] like Figure 4 As shown, further, an end of the first positioning portion 240 away from the inner side wall of the arc-shaped assembly portion 210 is provided with an extension portion 241 extending upward. It can be understood that by providing the extension portion 241, it is equivalent to increasing the height of the end of the first positioning portion 240 away from the inner side wall of the arc-shaped assembly portion 210, thereby increasing the contact area with the sensor 112 and further improving the positioning effect.

[0059] Combination Figure 2 and Figure 3 In some embodiments, the arc-shaped assembly portion 210 is further provided with a plurality of strip-shaped adjustment grooves 211 spaced apart along the arc length direction of the arc-shaped assembly portion 210 , and the strip-shaped adjustment grooves 211 extend along the radial direction of the arc-shaped assembly portion 210 .

[0060] It is understandable that the guide rail 111 can be fixed to the arc-shaped assembly portion 210 by screws, and the strip-shaped adjustment groove 211 can be used for the screws to pass through. The provision of the strip-shaped adjustment groove 211 can facilitate the adjustment of the installation position of the guide rail 111.

[0061] Specifically, a through hole is provided on the guide rail 111. While ensuring that the through hole is aligned with the strip adjustment groove 211, the needle seat 110 can be moved radially along the arc-shaped assembly portion 210 to adjust the installation position of the needle seat 110. After the installation position of the needle seat 110 is adjusted, the guide rail 111 can be fixed with bolts and nuts.

[0062] Furthermore, a mounting plate 300 is provided on the arc-shaped assembly portion 210, and a first through hole is provided on the mounting plate 300, and the first through hole is opposite to the strip-shaped adjustment groove 211. The guide rail 111 is provided on the mounting plate 300 and is provided with a second through hole opposite to the first through hole. The needle seat 110 and the mounting plate 300 can be fixed together on the arc-shaped assembly portion 210 by using bolts and nuts.

[0063] like Figure 2As shown, further, the inner end of the strip-shaped adjustment groove 211 is arranged toward the first positioning groove 240a, so that when the guide rail 111 is fixed, the sensor 112 can extend into the first positioning groove 240a.

[0064] It should be noted that, in some embodiments, a third positioning groove may be further provided on the needle seat positioning disk 200 to position the guide rail 111 , thereby further improving the positioning effect of the probe.

[0065] The present application also provides a core particle testing device, comprising the needle seat positioning plate 200 as described above.

[0066] In the core particle testing device of the present application, the needle seat 110 is used to be arranged on the arc-shaped assembly part 210, and when the needle seat 110 is arranged on the arc-shaped assembly part 210, the sensor 112 is limited to the first positioning groove 240a between two adjacent first positioning parts 240, and the probe mounting part 113 is limited to the second positioning groove 250a between two adjacent second positioning parts 250. Among them, the first positioning groove 240a can play a positioning role for the sensor 112, and the second positioning groove 250a can play a positioning role for the probe mounting part 113, thereby improving the positioning effect of the probe 120. At the same time, by setting a positioning structure on the needle seat positioning disk 200, it is not necessary to add a corresponding positioning structure on the needle seat 110, which can reduce the manufacturing and processing difficulty and cost of the needle seat 110. The needle seat positioning disk 200 of the present application can realize the installation of multiple probe devices 100. Under the joint action of multiple first positioning parts 240 and multiple second positioning parts 250, multiple probe devices 100 can be positioned, thereby ensuring the positioning effect of the needle tips of all probes 120, so that the needle tips of all probes 120 are arranged in an orderly manner.
