[0056] The outer wall of the embroidery needle storage box 3 is fixedly connected with a first return spring 4, and one end of the first return spring 4 is fixedly connected with the outer wall of the detection frame body 1;

[0057] This embodiment also discloses a detection method of an embroidery needle strength detection device, which includes the following steps:

[0058] S1, firstly, the embroidery needle bodies 7 to be tested are compactly arranged inside the embroidery needle storage box 3, and then the crawler conveyor belt 9 is started;

[0059] S2, with the start of the crawler conveyor 9, the second sleeve 14 contacts the outer wall of the embroidery needle storage box 3 and continuously pushes the embroidery needle storage box 3 to move, and at the same time, the electromagnet 19 is energized to suck the embroidery needle body 7 in the embroidery needle storage box 3 out of the discharge hole 8;

[0060] S3, as the crawler conveyor 9 continues to run, the embroidery needle body 7 sucked out in S2 will be abutted against the clamping plate 27 and pushed upward, so that the embroidery needle body 7 is abutted against the inner wall of the third sleeve 20 to start the rated pressure test. If it is not bent by pressing, it means that the test is qualified;

[0061] S4, as the crawler conveyor belt 9 continues to run, the embroidery needle body 7 that has been detected in S3 will fall into the collection box 2 for collection.

[0062] In this embodiment: when testing the existing embroidery needles currently on the market, it is usually necessary to manually place different batches of embroidery needles in the testing device for testing, which is inconvenient to automatically load the testing device when performing batch testing;

[0063] In order to facilitate automatic loading, before the detection, the multiple embroidery needle bodies 7 that need to be detected are evenly placed inside the embroidery needle storage box 3, and then the crawler conveyor 9 is started. After the crawler conveyor 9 is started, the first sleeve 11 on its outer wall moves along the running track of the crawler conveyor 9. When the first sleeve 11 moves, it will carry the two first guide cylinders 15 through the side wall of the detection frame body 1. At this time, the arc outer wall of the first ball head 17 exposed at the end of the first guide cylinder 15 and the side wall of the detection frame body 1 will conflict with each other, which will cause the first ball head 17 to be forced to squeeze the second return spring 16 into the first guide cylinder 15 to generate displacement, and gradually retract into the first guide cylinder 15 to prevent the first guide cylinder 15 from getting stuck when it conflicts with the side wall of the detection frame body 1.

[0064] And as the first sleeve 11 continues to move following the crawler conveyor 9, when the first guide cylinder 15 passes through the notch of the first guide slot 10, the second return spring 16 rebounds and brings the first ball head 17 into the first guide slot 10 to slide, and the first ball head 17 will contact the conductive sheet 13 provided in the first guide slot 10, and the conductive sheet 13 will be electrically connected to the first ball head 17, and the conductive sheet 13 will contact and communicate with the first guide cylinder 15 of the outer wall, and the first guide cylinder 15 is electrically connected to the second sleeve 14, the first support plate 18 and the electromagnet 19, so the electromagnet 19 is powered on and started, and the arrangement of the two first guide slots 10 and the corresponding two first guide cylinders 15 can make the movement of the first sleeve 11 and the second sleeve 14 more stable and will not twist;

[0065] When the second guide cylinder 24 hits the side wall of the detection frame body 1, the second ball head 33 will first move through the notch of the third guide slot 25. At this time, the fifth return spring 32 rebounds and brings the second ball head 33 into the third guide slot 25. When the second ball head 33 moves along the inner wall of the third guide slot 25, it will pass through the first section of the third guide slot 25 where it climbs upward. At this time, the second support plate 23 will move the second guide cylinder 24 upward. During the upward movement of the second guide cylinder 24, the second support plate 23 will move upward synchronously. The upward movement of the second support plate 23 will press the sixth return spring 251 upward along the second guide rod 241, and move the hollow moving frame 26 upward as a whole, causing the hollow moving frame 26 to be sleeved outside the third sleeve 20, as shown in the attached figure. Fig.11 The state shown causes the electromagnet 19 to be closer to the discharge hole 8, making it easier to absorb the embroidery needle body 7;

[0066] The thickness of the abutment block 29 is relatively large, which can prevent the clamping plate 27 from being out of contact with the abutment block 29 when following the movement of the hollow moving frame 26;

[0067] As the first sleeve 11 continues to move following the crawler conveyor belt 9, the second sleeve 14 will come into contact with the embroidery needle storage box 3 and push the embroidery needle storage box 3 to move a certain distance. When the second sleeve 14 comes into contact with the embroidery needle storage box 3, the magnetic pole of the electromagnet 19 is just facing the discharge hole 8 on the outer wall of the embroidery needle storage box 3. At this time, since the electromagnet 19 is in the starting state, the electromagnet 19 will suck the embroidery needle body 7 facing the discharge hole 8 in the embroidery needle storage box 3 upwards. Moreover, since the outer wall of the third sleeve 20 is provided with a guide slope 2001, the embroidery needle body 7 will be guided by the guide slope 2001 when it is sucked up, and finally be sucked to the end of the guide slope 2001 facing the electromagnet 19, as shown in the attached figure. Figure 2 As shown, since the guide slope 2001 is set to become narrower as it goes deeper, and the electromagnet 19 only produces a greater adsorption to the end position of the guide slope 2001, the embroidery needle body 7 is finally adsorbed to the end position of the guide slope 2001 and is in a vertical state, which is convenient for subsequent detection.

[0068] Whenever the embroidery needle body 7 facing the discharge hole 8 in the embroidery needle storage box 3 is sucked out, the electric telescopic rod 5 can be started, and the electric telescopic rod 5 drives the push plate 6 at the output end toward the discharge hole 8, so that the embroidery needle bodies 7 in the embroidery needle storage box 3 move uniformly toward the discharge hole 8, so that another embroidery needle body 7 faces the discharge hole 8, which is convenient for the next sucking out;

[0069] When the first guide cylinder 15 continues to move following the second sleeve 14, the first guide cylinder 15 slides along the first guide slot 10. Figure 2 As shown in the figure, there is an upward slope track. When the first guide cylinder 15 and the first ball head 17 on the outer wall slide through this upward slope track, the second sleeve 14 at the end of the first guide cylinder 15 will slide upward along the inner wall of the first sleeve 11;

[0070] The upward movement of the second sleeve 14 will cause the second sleeve 14 to release the conflicting state with the embroidery needle storage box 3. Figure 2 As shown in FIG. 1 , at this time, the embroidery needle storage box 3 will be pulled by the resilience of the first return spring 4 on the outer wall and start to return to the adjacent Figure 2 The initial position shown in , to facilitate the next needle removal;

[0071] And as the second sleeve 14 moves upward, the second support plate 23 and the hollow moving frame 26 will move upward synchronously, so that the inner wall of the hollow moving frame 26 inserts the longer part of the absorbed embroidery needle body 7 inside;

[0072] At this time, as the first guide cylinder 15 continues to slide in the first guide slot 10, the hollow moving frame 26 and the clamping plate 27 protruding from its outer wall will come into contact with the outer wall of the abutment block 29. At this time, the first inclined surface 28 of the outer wall of the clamping plate 27 will come into contact with the second inclined surface 30 of the outer wall of the abutment block 29, causing the clamping plate 27 to be subjected to a force moving toward the hollow moving frame 26. See the attached Figure 4 At this time, the clamping plate 27 will slide toward the inner wall of the hollow moving frame 26, so that the embroidery needle body 7 is above the clamping plate 27, limiting the position of the embroidery needle body 7;

[0073] When the first guide cylinder 15 continues to slide along the inner wall of the first guide slot 10, the second guide cylinder 24 will pass through the second section of the upward climbing trajectory in the third guide slot 25. At this time, the second guide cylinder 24 will be subjected to an upward force, and at the same time, it will carry the second support plate 23 to press the third return spring 22 upward along the outer wall of the first guide rod 21 and slide. The upward sliding distance of the second support plate 23 is determined by the slope of the third guide slot 25. Therefore, the second support plate 23 will slide upward by the same distance each time, that is, each time the second support plate 23 will press the sixth return spring 251 upward by the same distance, and after the sixth return spring 251 is stressed, the other end will press upward against the hollow moving frame 26 to force it upward. At this time, the hollow moving frame 26 moves upward synchronously, and the hollow moving frame 26 will carry the clamped embroidery needle body 7 to move upward, so that it is squeezed at the end of the guide slope 2001, and the force of squeezing is the same each time, so as to achieve the purpose of detecting the bending resistance. If the embroidery needle body 7 has not bent after being detected, it means that it has passed the detection.

[0074] As the first guide cylinder 15 continues to slide along the first guide slot 10, the first ball head 17 at the end of the first guide cylinder 15 will eventually break away from the contact with the conductive sheet 13. At this time, the electromagnet 19 will be powered off and the adsorption of the end of the embroidery needle body 7 will be released. At this time, the embroidery needle body 7 will fall into the collection box 2 for collection. The staff only needs to visually observe the bending degree of the embroidery needle body 7 to judge the detection result.

[0075] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0076] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
