In the prior art, after placing the needles on the workbench, the pressing wheel is used to press the position to be bent. However, during the processing, the positions where the needles on different models of probe cards need to be bent are also different. Therefore, it is necessary to adjust the position well each time the needles are placed, and it is also necessary to ensure that the needles are in the middle. But this is rather troublesome and cannot bend the needles continuously. Content of the Utility Model

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. In the present utility model, the needle is placed at the top of the support table. Then, the first cylinder is started to drive the limit frame to descend along the first cylinder, thereby driving the conveying wheel to descend, so that the surface of the conveying wheel contacts the needle.

Then, the needle is bent by the descent of the pressing wheel. At the same time, the second motor is started to drive the conveying wheel to convey the needle towards the pressing wheel, so that after the first bending, the second bending can be quickly carried out.

And after the first needle bending is completed, the second needle bending can be quickly carried out, greatly improving the needle bending efficiency.
[0013] 2. In the present utility model, the needle is placed at the top of the support table. Then, the needle is limited and conveyed by the clamping ring and the conveying wheel. After the pressing wheel bends the needle, the third motor is started to drive the support rod to turn over, thereby driving the support table to turn over. Then, through the turning over of the support table, the needles at the top of the support table quickly fall off, thus realizing the quick blanking of the needles after the needle bending is completed, thereby improving the blanking efficiency and further improving the needle bending efficiency.

Specific implementation mode
[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] As Figures 1 to 5 shown, the present invention provides a needle bending machine device for probe card bent needles, including a support frame 1. The top end of the support frame 1 is fixedly connected with a first cylinder 2. The output end of the first cylinder 2 is fixedly connected with a limit frame 3. The rear side of the limit frame 3 is fixedly connected with a first motor 4. The output shaft of the first motor 4 is fixedly sleeved with a bidirectional threaded rod 5. The surface of the bidirectional threaded rod 5 is engaged with a moving ring 6. The bottom end of the moving ring 6 is fixedly connected with a clamping ring 7. The rear side of the limit frame 3 is fixedly connected with a second motor 8. The output shaft of the second motor 8 is fixedly sleeved with a conveying wheel 9;
[0022] By placing the needle on the top end of the support table 15, then starting the first cylinder 2 to drive the limit frame 3 to descend along the first cylinder 2, thereby driving the conveying wheel 9 to descend, so that the surface of the conveying wheel 9 contacts the needle. Then start the first motor 4 to drive the bidirectional threaded rod 5 to rotate. By the rotation of the bidirectional threaded rod 5, drive the engaged moving ring 6 to move along the axis direction of the bidirectional threaded rod 5 and the conveying wheel 9, thereby clamping and limiting the needle through the clamping ring 7. Then bend the needle by the descent of the pressing wheel 12. At the same time, start the second motor 8 to drive the conveying wheel 9 to convey the needle towards the pressing wheel 12, so that after the first bending, the second bending can be quickly carried out, thereby realizing the clamping and limiting of needles with different specifications through the movement of the clamping ring 7, enabling the needle to quickly locate at the center, and through the conveying of the needle by the conveying wheel 9, it can be quickly adjusted to the position where the needle needs to be bent, and after the first needle bending is completed, the second needle bending can be quickly carried out, greatly improving the needle bending efficiency.
[0023] Among them, the left side of the support frame 1 is fixedly connected with a third motor 13. The output shaft of the third motor 13 is fixedly sleeved with a support rod 14. The front side of the support rod 14 is fixedly connected with a support table 15;
[0024] By placing the needle at the top of the support table 15, then limiting and conveying the needle through the clamping ring 7 and the conveying wheel 9, after the pressing wheel 12 finishes bending the needle, start the third motor 13 to drive the support rod 14 to turn, thereby driving the support table 15 to turn. Then, through the turning of the support table 15, the needle at the top of the support table 15 quickly drops, thus realizing the rapid blanking of the bent needle, improving the blanking efficiency, and further improving the bending efficiency of the needle.
[0025] Among them, a second cylinder 10 is fixedly connected to the top of the support frame 1, and a mounting frame 11 is fixedly sleeved on the output shaft of the second cylinder 10. A pressing wheel 12 is movably sleeved in the inner cavity of the mounting frame 11;
[0026] After the position of the needle is adjusted by the clamping ring 7 and the conveying wheel 9, start the second cylinder 10 to drive the mounting frame 11 to move along the axis of the second cylinder 10, so that the pressing wheel 12 presses the needle, thereby bending the needle. And due to the rotatability of the pressing wheel 12, when bending the needle, there will be no jamming.
[0027] Among them, the clamping ring 7 is movably sleeved on the surface of the conveying wheel 9, and the bottom end of the clamping ring 7 is a convex arc plate;
[0028] By movably sleeving the clamping ring 7 on the surface of the conveying wheel 9, the conveying wheel 9 positions and guides the clamping ring 7, so that when the bidirectional threaded rod 5 rotates to drive the moving ring 6 to move, the clamping ring 7 can position and guide the moving ring 6, avoiding the moving ring 6 from shifting during the movement. Then, due to the bottom end of the clamping ring 7 being a convex arc plate, the bottom end of the clamping ring 7 can clamp the needle.
[0029] Among them, the conveying wheel 9 and the pressing wheel 12 are on the same axis, and the pressing wheel 12 is located on the right side of the conveying wheel 9;
[0030] By the conveying wheel 9 and the pressing wheel 12 being on the same axis, the conveying wheel 9 can convey the needle towards the pressing wheel 12, so that the pressing wheel 12 can press the needle when descending, thus bending the needle.
[0031] Among them, a rectangular plate is fixedly connected to the left side of the support frame 1, and the third motor 13 is fixedly installed on the left side of the rectangular plate;
[0032] By installing the third motor 13 through the rectangular plate on the left side of the support frame 1, the third motor 13 can support the support table 15, and then support the needle through the support table 15, so that the needle can move on the top of the support table 15, and then the pressing wheel 12 can bend the needle.
[0033] Wherein, a fixing frame 16 is fixedly connected to the right side of the rectangular plate, the support rod 14 is movably sleeved in the inner cavity of the fixing frame 16, and the right side of the support table 15 is a curved surface;
[0034] Through the fixing frame 16 on the right side of the rectangular plate, the support rod 14 can be supported by the fixing frame 16, so that the motor three 13 can drive the support rod 14 to flip more stably. Then, because the right side of the support table 15 is a curved surface, when the pressing wheel 12 presses the needle, the curved surface of the support table 15 supports the bottom of the needle, preventing the bottom of the needle from hanging in the air and enabling the needle to be bent more stably.
[0035] The working principle and usage process of the present utility model are as follows: Place the needle on the top of the support table 15. Then start the cylinder one 2 to drive the limiting frame 3 to descend along the cylinder one 2. Next, start the motor one 4 to drive the bidirectional threaded rod 5 to rotate, thereby driving the mating moving ring 6 to move along the axis directions of the bidirectional threaded rod 5 and the conveying wheel 9, changing the distance between the two clamping rings 7, and then clamping and limiting the needle through the two clamping rings 7. Then start the motor two 8 to drive the conveying wheel 9 to rotate, and then convey the needle towards the pressing wheel 12 through the rotation of the conveying wheel 9. Next, start the cylinder two 10 to drive the mounting frame 11 to move along the cylinder two 10, thereby driving the pressing wheel 12 to press the needle, causing the needle to bend. And then the motor two 8 can be started to drive the conveying wheel 9 to rotate to continuously convey the needle, so as to continuously bend the needle;
[0036] After bending, start the motor three 13 to drive the support rod 14 to flip, thereby driving the support table 15 to flip, and then the bent needle on the top of the support table 15 slides into the collection device for collection.
