[0019] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments may be combined with each other.

[0020] As Figures 1 to 5In the embodiment of the computerized sewing needle inspection device of the present utility model shown, the computerized sewing needle inspection device includes a clamping table 1. A needle hole 2 adapted to the sewing needle is provided on the clamping table 1. Guide rods 3 are fixedly connected to both sides of the clamping table 1. A thimble seat 4 is slidably connected to one side guide rod 3 of the clamping table 1. An elastic thimble 5 is installed on the thimble seat 4, and the elastic thimble 5 corresponds to the needle hole 2. An inspection plate 6 is slidably connected to the other side guide rod 3 of the clamping table 1. An inspection hole 7 is provided on the inspection plate 6, and an elastic petal hole 8 is fixedly connected to the inspection hole 7.

[0021] Specifically, place the sewing needle to be inspected in the needle hole 2 of the clamping table 1. Move the thimble seat 4 towards the clamping table 1. The elastic thimble 5 abuts against the shank of the sewing needle to push the sewing needle. Those with unqualified diameters are pushed out of the clamping table 1 under the push of the thimble, and those qualified are blocked by the clamping table 1 to cause the elastic thimble 5 to retract. After the elastic thimble 5 is tightened, move the inspection plate 6 to slide on the guide rod 3 to the position of the needle tip. Those that cannot enter the inspection hole 7 or push open the petal hole 8 are unqualified in terms of bending degree. The shank of the qualified sewing needle extends out of the inspection hole 7, and the needle tip extends out of the petal hole 8.

[0022] In an embodiment of the present application, preferably, a telescopic hole 9 for the elastic thimble 5 to expand and contract is provided in the thimble seat 4. A limiting plate 10 is fixedly connected to the elastic thimble 5 in the telescopic hole 9. A spring 11 is installed in the telescopic hole 9, and the spring 11 abuts against the limiting plate 10, which is used to make the elastic thimble 5 extend or retract when encountering resistance in the telescopic hole 9.

[0023] In an embodiment of the present application, preferably, a connector for connecting the sewing needle is provided at the head of the elastic thimble 5, which is used to fix the sewing needle by the elastic thimble 5 and ensure the stability of the sewing needle during movement.

[0024] In an embodiment of the present application, preferably, the connector includes a clamping plate 12 and a magnet 13. The magnet 13 is a concave magnet, and the concave surface of the magnet 13 is adapted to the protrusion at the tail of the sewing needle. The clamping plate 12 is adapted to the plane of the shank of the sewing needle, which is used to connect the sewing needle to prevent it from falling off, and the clamping plate 12 clamps the sewing needle for limiting the sewing needle.

First, move the thimble seat 4 along the guide rod 3 until the connector of the elastic thimble 5 is connected to the shank of the machine needle. Move the inspection plate 6 to the position of the needle tip, and continue to move the thimble seat 4. Under the thrust of the thimble seat 4, the unqualified machine needles are pushed out from the needle hole 2, and the qualified machine needles cause the elastic thimble 5 to retract spirally. The machine needles are rotated with the elastic thimble 5 under the influence of the connector clamping plate 12. During this process, the machine needles that cannot extend into the inspection hole 7 or open the petal hole 8 or open the petal hole 8 during rotation are regarded as unqualified in terms of the degree of bending. This device uses the needle hole 2 of the clamping table to slide and eject the machine needles with diameters not meeting the standard when clamping the machine needles by the elastic thimble 5. The qualified machine needles cause the elastic thimble 5 to retract. Slide the inspection plate 6. The bent machine needles cannot pass through the inspection hole 7 or open the petal hole 8. By using the movement track of the needle tip when the bent machine needle rotates, the petal hole 8 can be opened, so as to inspect the diameter and bending condition of the machine needle, and the inspection efficiency is high.
