[0006] Furthermore, the second through hole is frustum-shaped, and the angle between the generatrix of the second through hole and the shaft is a second angle, the angle between the generatrix of the first through hole and the shaft is a first angle, and the angle of the second angle is smaller than the angle of the first angle.

[0007] Furthermore, the included angle of the first included angle is 40~60°; the included angle of the second included angle is 20~40°.

[0008] Furthermore, the included angle of the first included angle is 45°; the included angle of the second included angle is 30°.

[0009] Furthermore, the array of through holes also includes a third through hole coaxially arranged with the first through hole. The upper end of the third through hole is connected to the lower end of the second through hole. The third through hole has a cylindrical structure and its diameter is larger than the outer diameter of the needle tube.

[0010] Furthermore, the array of through holes also includes a fourth through hole coaxially arranged with the first through hole, the upper end of the fourth through hole being connected to the lower end of the third through hole, and the diameter of the fourth through hole being smaller than the outer diameter of the needle tube.

Detailed Implementation

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] See appendix Figure 1-2 As shown in this embodiment, a semi-automatic probe component alignment fixture is used to neatly arrange the probe components (needles) during the probe assembly process.

[0023] The fixture includes a negative pressure assembly, which includes a base 1. A groove 11 is provided on the upper side of the base 1, and a negative pressure through hole 12 is provided on the side wall of the groove 11. The negative pressure through hole 12 connects the outside of the base 1 and the groove 11. A negative pressure mechanism is provided on the outside of the base 1, and the negative pressure mechanism is connected to the negative pressure through hole 12. The negative pressure mechanism can draw away the gas in the groove 11, so that the groove 11 is in a negative pressure state.

[0024] See appendix Figure 2-4 As shown, the alignment fixture includes an alignment plate 2 for arranging needles. Alignment through holes 21 are provided along the thickness direction of the alignment plate 2, and the alignment through holes 21 are perpendicular to the upper or lower surface of the alignment plate 2.

[0025] The alignment plate 2 is positioned directly above the base 1. The alignment through hole 21 and the groove 11 are connected. When the groove 11 is in a negative pressure state under the action of the negative pressure mechanism, it has an adsorption effect on the alignment through hole 21, making the alignment through hole 21 in a negative pressure state.

[0026] By setting up the negative pressure component, the entire row of through holes is in a negative pressure state. During the needle arrangement process, the needle is placed above the row plate 2, and the base 1 is shaken. Under the action of negative pressure, the needle enters the row of through holes 21, completing the arrangement of the needle and improving the efficiency of the entire row of needles.

[0027] In some embodiments, the through-hole 21 includes a first through-hole 211, a second through-hole 212, a third through-hole 213, a fourth through-hole 214, and a fifth through-hole 215 that are sequentially connected from the upper side to the lower side of the aligning plate 2. The first through-hole 211 is a frustum-shaped hole that is wider at the top and narrower at the bottom. By setting the first through-hole 211 to a frustum-shaped hole, it is beneficial for the needle located above the aligning plate 2 to enter the through-hole 21.

[0028] In some embodiments, the third through hole 213 is a cylindrical structure, and the diameter of the third through hole 213 is larger than the outer diameter of the needle tube, so that the needle tube can smoothly enter the third through hole 213.

[0029] In some embodiments, the second through hole 212 is frustum-shaped, and the angle between the generatrix of the second through hole 212 and the shaft is a second included angle 2121, the angle between the generatrix of the first through hole 211 and the shaft is a first included angle 2111, and the angle of the second included angle 2121 is smaller than the angle of the first included angle 2111.

[0030] By providing a second through hole 212 between the first through hole 211 and the third through hole 213, and by setting the angle of the second included angle 2121 to be smaller than the included angle of the first included angle 2111, the needle can more easily stand upright and enter the third through hole 213 after entering the first through hole 211.

[0031] In some embodiments, the included angle of the first included angle 2111 is 40~60°, preferably 45°; the included angle of the second included angle 2121 is 20~40°, preferably 30°.

[0032] In some embodiments, the fourth through hole 214 is a cylindrical structure, and the diameter of the fourth through hole 214 is smaller than the outer diameter of the needle tube, so that the needle tube can enter the third through hole 213 to support the needle tube and prevent the needle tube from slipping into the groove 11.

[0033] In some embodiments, the diameter of the fifth through hole 215 is larger than that of the fourth through hole 214, which is beneficial for the negative pressure mechanism to adsorb the gas in the row of through holes 21, and then adsorb the needle.

[0034] The array of through holes 21 includes a first through hole 211, a second through hole 212, a third through hole 213, a fourth through hole 214, and a fifth through hole 215, all with different shapes and diameters, connected sequentially to facilitate the smooth entry of needles into the array of through holes 21. The negative pressure component creates a negative pressure within the array of through holes 21, which attracts the needles. Once a needle enters the array of through holes 21, it blocks the array of through holes 21, preventing other needles from entering. Needles that do not enter the array of through holes 21 can be removed.

[0035] See appendix Figure 5 As shown, in some embodiments, a plurality of positioning pins 4 are provided on the base 1. The positioning pins 4 are perpendicular to the upper surface of the base 1 and are distributed circumferentially around the groove 11. Positioning holes are provided on the aligning plate 2. The position and size of the fixing holes are adapted to the position of the positioning pins 4. The positioning holes can be fitted onto the positioning pins 4, thereby fixing the aligning plate 2. Fixing the aligning plate 2 with the positioning pins 4 and positioning holes makes the aligning plate 2 easy to disassemble. When it is necessary to align needles of different specifications, only the aligning plate 2 needs to be replaced, which improves the adaptability of the aligning fixture.

[0036] In some embodiments, an inwardly recessed groove is provided at the junction of the lower side and the left / right side of the array plate 2, serving as a handle 22 for replacing the array plate 2, so as to facilitate the replacement of the array plate 2.

[0037] In some embodiments, a protective enclosure 3 is provided above the alignment plate 2. The protective enclosure 3 is connected to the upper side of the alignment plate 2 near the edge and is arranged circumferentially with the alignment through hole 21 as the center. The protective enclosure 3 prevents the needle from falling off the edge of the alignment plate 2 during the alignment process.
