[0029] The present invention discloses a rotary dotting machine, as Figure 1 and Figure 2 shown, which includes a carrier plate 1. One end of the carrier plate 1 is connected with a dotting die 3 through a turntable 2. A needle shaft 4 is provided on a side wall of the dotting die 3. The needle shaft 4 is connected with a dotting cylinder 6 through a locking sleeve 5. Pad screws 10 are provided at the bottoms of the four corners of the carrier plate 1, and the pad screws 10 are used to support the carrier plate 1.

[0030] The dotting die 3 is fixed on the turntable 2. The turntable 2 is arranged on the carrier plate 1. A rotary cylinder 11 is fixed under the carrier plate 1, and the turntable 2 is connected with the rotary end of the rotary cylinder 11. When the pneumatic rotary cylinder 11 is actuated, the rotary end of the rotary cylinder 11 drives the turntable 2 to rotate, and further drives the dotting die 3 to rotate.

[0031] Place the product to be dotted on the dotting die 3, start the dotting cylinder 6. The dotting cylinder 6 drives the locking sleeve 5, and further drives the needle shaft 4 to perform dotting and forming on the product to be dotted placed on the dotting die 3. After forming, restore the dotting cylinder 6 to the starting position, then start the rotary cylinder 11. The rotary end of the rotary cylinder 11 drives the turntable 2 to rotate, and further drives the dotting die 3 to rotate to another side wall of the dotting die 3, and then start the dotting cylinder 6 again to realize dotting and forming processing on the other side of the probe needle tube again. Repeat the above process as needed.

[0032] The rotary dotting machine of the present invention is specifically used for dotting and forming processing of microelectronic hardware test probes, and solves the problem that existing large-scale production equipment cannot perform forming processing.

[0033] The rotary dotting machine of the present invention can realize dotting and forming processing of hardware test probes by arranging a needle shaft 4 on a side wall of the dotting die 3. Moreover, the rotary dotting machine of the present invention is easy to operate, can not only ensure the quality of dotting and forming, but also improve the efficiency of the dotting and forming process, and has a good market promotion and application prospect.

[0034] AsFigure 3 and Figure 4 As shown in Figure 4 , screw through holes 3-1 are respectively provided at the four corners of the dotting die 3. Screws pass through the screw through holes 3-1 to fix the dotting die 3 on the turntable 2. A product placement hole 3-2 is provided at the middle position of the top of the dotting die 3. The product placement hole 3-2 is used to place the product to be dotted. A plurality of dotting needle shaft holes 3-3 arranged vertically in a single column are respectively provided on the four side walls of the dotting die 3, and the dotting needle shaft holes 3-3 communicate with the product placement hole 3-2. One end of the needle shaft 4 is connected to the locking sleeve 5, and the other end of the needle shaft 4 passes through the dotting needle shaft hole 3-3 to perform dotting forming on the product to be dotted. A rear positioning screw hole 3-4 is provided at the middle position of the bottom of the dotting die 3.

[0035] The product placement hole 3-2 is at a certain distance from the bottom of the dotting die 3, and the center of the product placement hole 3-2 coincides with the center of the rear positioning screw hole 3-4. In this structure, the product placement hole 3-2 and the rear positioning screw hole 3-4 are not connected, and the rear positioning screw hole 3-4 realizes the positioning of the dotting die 3 on the turntable 2 through the rear positioning screw.

[0036] Or, the product placement hole 3-2 is connected to the rear positioning screw hole 3-4, and a positioning screw is provided in the rear positioning screw hole 3-4. The positioning screw is used to limit the height of the product placement hole 3-2. The positioning screw passes through the turntable 2 and inserts into the rear positioning screw hole 3-4 to limit the height of the product placement hole 3-2.

[0037] As Figure 1 shown in Figure 1 , a needle shaft guiding screw 7 is sleeved outside the needle shaft 4, and the needle shaft guiding screw 7 is fixed on the needle shaft bracket 8 through a nut. The function of the needle shaft guiding screw 7 is to ensure that the needle shaft 4 will not deviate, and at the same time, it can ensure that the needle shaft 4 will not break during operation.

[0038] It should be noted here that the needle shaft guiding screw 7 is provided with a through hole along the length direction at the center, and the needle shaft 4 passes through the through hole, so that the needle shaft guiding screw 7 is sleeved outside the needle shaft 4.

[0039] As Figure 5 shown in Figure 5 , the needle shaft bracket 8 is in an "L" shape. A first "U" shaped groove 8-1 is provided on the long side of the "L" shaped structure of the needle shaft bracket 8. The needle shaft guiding screw 7 is arranged in the first "U" shaped groove 8-1 and is fixed through a nut. Since the first "U" shaped groove 8-1 has a certain height, the height (up and down position) of the needle shaft guiding screw 7 in the first "U" shaped groove 8-1 can be adjusted. The bottom of the "L" shape of the needle shaft bracket 8 is fixed on the carrier plate 1 through screws.

[0040] As Figure 6As shown, one end of the locking sleeve 5 is provided with a threaded hole (not shown in the figure), and the threaded hole is connected to the telescopic end of the dotting cylinder 6 through a thread. The other end of the locking sleeve 5 is provided with a hole 5-1. One end of the needle shaft 4 is inserted into the hole 5-1 of the locking sleeve 5, and the other end of the needle shaft 4 passes through the dotting needle shaft hole 3-3 to perform dotting and forming on the product to be dotted. On the side wall of the end of the locking sleeve 5 connected to the needle shaft 4, there is a needle shaft locking screw 5-2, and the needle shaft locking screw 5-2 is used to fix the needle shaft 4.

[0041] As Figure 1 shown, the dotting cylinder 6 is fixed on the carrier plate 1 through the cylinder bracket 9. As Figure 6 shown, the cylinder bracket 9 is in an "L" shape. There are two second "U" - shaped grooves 9-1 on the long side of the "L" - shaped structure of the cylinder bracket 9. The fixing screw at the tail of the dotting cylinder 6 passes through the second "U" - shaped groove 9-1 and is tightened with a nut to realize the fixing of the dotting cylinder 6 on the cylinder bracket 9. Since the second "U" - shaped groove 9-1 has a certain height, the height (up and down position) of the dotting cylinder 6 can be adjusted. There are two third "U" - shaped grooves 9-2 on the short side of the "L" - shaped structure of the cylinder bracket 9. The screws pass through the third "U" - shaped groove 9-2 and the carrier plate 1 in sequence and are fixed by nuts, which can fix the cylinder bracket 9 on the carrier plate 1. At the same time, the screws also have the function of supporting the dotting cylinder 6.

[0042] For the rotary dotting machine of the present invention, during use, the product to be dotted is placed in the product placement hole 3-2 on the dotting die 3. The dotting cylinder 6 is started, and the dotting cylinder 6 drives the needle shaft 4 fixed on the locking sleeve 5, and performs dotting and forming on the product to be dotted placed in the product placement hole 3-2 through the needle shaft guiding screw 7. After forming, the dotting cylinder 6 will return to the starting position, then the rotary cylinder 11 is started. The rotating end of the rotary cylinder 11 drives the turntable 2 to rotate, further driving the dotting die 3 to rotate to the other side wall of the dotting die 3. The dotting cylinder 6 is started again to realize dotting and forming processing on the other side of the probe needle tube again. Repeat the above process as needed.

[0043] Since the height of the dotting cylinder 6 and the height of the needle shaft guiding screw 7 can both be adjusted, after the first dotting and forming, the height of the needle shaft can be adjusted to realize dotting at different heights of different probe needle shafts.
