[0021] The silicon resistivity detection device of this embodiment can use the knob 21 to accurately control the lifting and lowering of the adjustment bracket 19, so that the lifting degree of the probe 12 is accurately controlled, thereby accurately controlling the extension and retraction length of the probe on the probe 12 to find the most accurate extension and retraction amount for detecting the resistance value, and the guide rail 13 can enable the translation bracket 11 to move back and forth, thereby improving the flexibility and convenience of detection.
[0022] The silicon resistivity detection device of the present embodiment is used as follows: first, place the product to be tested on the machine table 10, push the translation bracket 11 to move the probe 12 to the vicinity of the product's area to be tested, then rotate the knob 21 to lower the adjustment bracket 19 until the probe on the probe 12 abuts against the product, and continue to slightly rotate the knob 21 to accurately control the extension length of the probe on the probe 12. At the same time, the pointer of the dial indicator 18 will abut against the pressing piece 20, thereby displaying the fine-tuning amount, so as to find the most accurate extension amount for detecting the resistance value, and finally complete the resistivity detection through the probe 12.
[0023] In combination with the above-mentioned usage method, it can be known that in this embodiment, the adjustment bracket 19 is raised and lowered relative to the adjustment fixing base 17 by rotating the knob 21, wherein the rotational movement of the knob 21 is converted into the lifting and lowering movement of the adjustment bracket 19 through the engagement of the gear rack, and due to the engagement of the gear rack, the finer the gear rack, the more accurately the lifting and lowering movement can be controlled.
[0024] In some embodiments, a mounting block 22 is further included, and the mounting block 22 is fixedly connected to the translation bracket 11. A mounting hole is provided on the mounting block 22, and one side of the mounting hole has an opening. The connecting rod 15 is clamped in the mounting hole, and a locking member is fixedly provided near the opening on the mounting hole. Thus, the connecting rod 15 is clamped by the mounting hole fixed to the translation bracket 11. Specifically, the opening amplitude of the mounting hole can be reduced by locking the locking member such as the bolt 27, thereby reducing the diameter of the mounting hole, thereby achieving a stable clamping of the connecting rod 15. Moreover, due to the provision of the locking member such as the screw and the bolt 27, the disassembly can be easily achieved, so that the mounting block 22 can adjust its position relative to the connecting rod 15, thereby better adapting to the thickness characteristics of the product to be tested and improving the convenience of use.

[0026] In some embodiments, the locking seat 16 includes a first locking block 161 and a second locking block 162, the first locking block 161 and the second locking block 162 are connected by a locking member, and the dial gauge 18 and the connecting rod 15 are sandwiched between the first locking block 161 and the second locking block 162. In this embodiment, the first locking block 161 and the second locking block 162 can clamp the dial gauge 18 and the connecting rod 15 at the same time through a locking member such as a bolt 27 or a screw, so that the dial gauge 18 is fixed to the connecting rod 15. And due to the provision of the locking member such as the screw, the bolt 27, etc., it can be easily disassembled, so that the locking seat 16 can adjust its position relative to the connecting rod 15, so as to better adapt to the thickness characteristics of the product to be tested and improve the convenience of use.
[0027] In a further embodiment, the first locking block 161 and the second locking block 162 are provided with a snap-fitting member 163, and the dial indicator 18 is fixed to the locking seat 16 through the snap-fitting member 163. Figure 2 As shown, the first locking block 161 and the second locking block 162 are provided with staggered bosses to form an engaging member 163 , and part of the dial indicator 18 can be fixed by the engaging member 163 .
[0028] In other embodiments, a storage table 25 is provided on the machine 10, and the storage table 25 is rotatably matched with the machine 10.

[0030] In other embodiments, a second guide rail is provided on the translation bracket 11 along the extension direction, a second slider is provided on the second guide rail, and the connecting rod 15 is fixedly connected to the second slider. Thus, the connecting rod 15 can be moved along the extension direction of the translation bracket 11, thereby further improving the flexibility of the probe 12 and further improving the convenience of use.
[0031] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
