Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The needle feeding mechanism 2 is located directly below the detection and positioning mechanism 3 and is connected to the first lifting mechanism 1. The first lifting mechanism 1 is arranged on the carrying mechanism 6, so that the needle feeding mechanism 2 is driven to move up and down by the first lifting mechanism 1;

[0035] The needle loading detection mechanism 5 moves downward through the retaining frame and docks with the needle feeding mechanism 2, so that the needle roller is fed into the needle loading detection mechanism 5 through the needle feeding mechanism 2. The needle feeding mechanism 2 cooperates with the needle loading detection mechanism 5 to detect the length of the needle roller, and the needle loading detection mechanism 5 discharges the needle roller with unqualified size.

[0038] In a further embodiment, a distance measuring sensor A32 for detecting the moving position of the piston plate 34 is provided in the positioning detection chamber 37. The distance measuring sensor A32 detects the positions of the piston plate 34 and the positioning plate 31, and then determines whether the positioning plate 31 is inserted into the positioning needle groove of the retaining frame to position the retaining frame, and can determine whether there is a missing needle in the retaining frame.

[0039] In this embodiment, according to Figure 2 , Figure 7 As shown, the needle feeding mechanism 2 includes a needle feeding body 29, in which a plurality of rising channels 24 corresponding to the rolling needles are axially penetrated, and needle delivery channels 25 respectively connected to the rising channels 24 are radially provided. The needle feeding body 29 is respectively provided with loading ports 22 connected to the needle delivery channels 25 so as to be used for loading the rolling needles into the needle delivery channels 25. The horizontal needle pushing mechanism 21 arranged on the needle feeding body 29 is connected with the pushing block 26 located in the needle delivery channel 25 so as to push the rolling needles into the rising channel 24 through the pushing block 26. The needle feeding body 29 is provided with a vertical needle pushing mechanism 28 corresponding to the rising channel 24. The output end of the vertical needle pushing mechanism 28 is penetrated into the rising channel 24 so as to push the rolling needles from the rising channel 24 into the needle loading detection mechanism 5, and the output end of the vertical needle pushing mechanism 28 plays a role of auxiliary support for the rolling needles. In a further embodiment, the horizontal needle pushing mechanism 21 is installed on the outer side of the needle feeding body 29, and the horizontal needle pushing mechanism 21 is arranged corresponding to the needle delivery channel 25.

[0040] In a further embodiment, the butt end of the needle feeding body 29 is configured as a step end 23 so that the butt end of the needle feeding body 29 matches the port of the retaining frame, thereby facilitating the placement of the needle roller at the center of the retaining frame and facilitating the needle installation.

[0041] In a further embodiment, the vertical needle pushing mechanism 28 is installed on the needle feeding body 29 via a bracket 27 .

[0042] In this embodiment, according to Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the needle loading detection mechanism 5 includes a needle loading body 52 for docking with the needle feeding mechanism 2, and the end of the needle loading body 52 is axially provided with a plurality of needle roller receiving grooves 513 for loading needle rollers, and the needle roller receiving grooves 513 are distributed in a circle with the central axis of the needle loading body 52 as the center, and the inner wall of the needle roller receiving groove 513 is provided with a receiving plate groove 517 for loading the needle push plate 51, and the needle loading body 52 is provided with a needle push cavity 516 corresponding to the receiving plate groove 517, and the needle push plate 51 is provided with a needle push cavity 516 corresponding to the receiving plate groove 517. The push pin plate 51 for piston motion arranged in the cavity 516 is connected to the push pin plate 51 in the receiving plate groove 517 through a connecting rod 515. The push pin cavity 516 is connected to the oil supply unit 56 installed on the needle loading body 52 through a pipeline, thereby driving the push pin plate 51 to move and push the needle into the positioning needle roller groove of the retainer. Solenoid valves 55 are respectively arranged on the pipeline to realize independent control of the push pin. The needle loading body 52 is provided with a detection groove 58 corresponding to the needle roller receiving groove 513. A detection rod 511 corresponding to the detection groove 58 is axially arranged in the needle loading body 52, one end of the detection rod 511 is connected to the position detection plate 59 located in the detection groove 58, and the other end is connected to the pressure block 514 located in the needle roller receiving groove 513, and a pressure spring 512 sleeved on the detection rod 511 is arranged in the needle roller receiving groove 513, so that the pressure block 514 presses the end of the needle roller, and a distance sensor B54 for detecting the displacement of the position detection plate 59 is arranged on the needle loading body 52, and the distance sensor B54 is located directly above the position detection plate 59, and the pressure spring 512 pushes the pressure block 514 to press one end of the needle roller, and the needle feeding mechanism 2 supports the other end of the needle roller, and the distance sensor B54 detects the displacement of the position detection plate 59 to determine whether the length of the needle roller meets the size requirements, if not, the defective product can be pushed out of the needle roller receiving groove 513 by the needle pushing plate 51, and then the needle roller is sent into the needle roller receiving groove 513 again by the needle feeding mechanism 2.

[0043] In a further embodiment, an air hole 518 is formed on the inner wall of the needle roller receiving groove 513, and the air hole 518 is communicated with the air cavity 510 constructed in the needle loading body 52. ​​The air cavity 510 is a special-shaped structure, and the needle loading body 52 is provided with an exhaust unit 57 for exhausting air in the air cavity 510. The air cavity 510 is arranged corresponding to the needle roller receiving grooves 513 distributed along the circumference, and the air cavity 510 is located in the center of the needle roller receiving groove 513. This design ensures that the needle roller is in a vertical state during length detection to avoid errors caused by tilt and offset of the needle roller sent into the needle roller receiving groove 513, thereby ensuring the accuracy of the detection.

[0044] In a further embodiment, a central channel 53 is axially penetrated in the needle mounting body 52, and the central channel 53 is used to accommodate the electromagnetic valve 55 and the pipeline, and the internal structure is compact.

[0045] Working principle: a retaining frame is placed in the needle loading channel 39 of the detection and positioning mechanism 3, and the detection and positioning mechanism 3 positions and carries the retaining frame, and then the second lifting mechanism 4 drives the needle loading detection mechanism 5 to move downward, and the needle loading detection mechanism 5 passes through the center of the retaining frame and docks with the needle feeding mechanism 2, and the needle feeding mechanism 2 sends the needle roller into the needle loading detection mechanism 5. During this process, the needle feeding mechanism 2 cooperates with the needle loading detection mechanism 5 to detect the length of the needle roller, wherein the needle feeding mechanism 2 plays a supporting role for the needle roller, and the needle loading detection mechanism 5 will remove the needle roller with poor size from the inside, and after completion, the needle feeding mechanism 2 and the needle loading detection mechanism 5 move upward together until the docking point of the needle feeding mechanism 2 and the needle loading detection mechanism 5 is located in the retaining frame, and the needle loading detection mechanism 5 can push the needle roller into the positioning needle roller groove of the retaining frame for needle loading;

[0046] Specifically, after the needle feeding mechanism 2 is docked with the needle loading detection mechanism 5, the horizontal needle pushing mechanism 21 drives the pushing block 26 to push the needle roller into the rising channel 24, and then the vertical needle pushing mechanism 28 pushes the needle roller out of the rising channel 24, and then pushes it axially into the needle roller receiving groove 513 of the needle loading detection mechanism 5. At this time, the output end of the vertical needle pushing mechanism 28 supports one end of the needle roller, and the other end of the needle roller abuts against the pressure block 514. The pressure block 514 pushes the position detection plate 59 to move through the detection rod 511. Since the distance measuring sensor B54 monitors the displacement of the position detection plate 59 in real time, the needle roller with qualified size will make the distance between the output end of the vertical needle pushing mechanism 28 and the pressure block 514 within a certain numerical range. When the size is less than or greater than this value, it means that the needle roller size is unqualified. When the size of the needle roller in the needle roller receiving groove 513 is unqualified, the corresponding solenoid valve 55 is opened, and the oil enters the corresponding push needle cavity 516 to push the push needle plate 51 to move, thereby pushing out the unqualified needle roller in the needle roller receiving groove 513;

[0047] After the retaining frame is placed in the needle loading channel 39, the positioning plate 31 is inserted into the positioning needle roller groove of the retaining frame under the thrust of the strong spring 36 to position and load the retaining frame. When the needle loading detection mechanism 5 and the needle feeding mechanism 2 move up together until the needle roller accommodating groove 513 corresponds to the positioning needle roller groove of the retaining frame, the needle pushing plate 51 pushes the needle roller from the needle roller accommodating groove 513 into the retaining frame window. At the same time, the positioning plate 31 is hidden in the positioning movement chamber 38, and the piston plate 34 compresses the strong spring 36. In order to prevent the positioning plate 31 from pushing the needle roller back into the needle roller accommodating groove 513 under the elastic force of the strong spring 36, after the needle roller is loaded on the retaining frame, the vacuum pump 35 evacuates the positioning detection chamber 37 to put it in a negative pressure state, thereby keeping the positioning plate 31 in the positioning movement chamber 38. Finally, the needle loading detection mechanism 5 is lifted up and the needle feeding mechanism 2 is lifted up accordingly, and then the retaining frame full of needle rollers is pushed out of the needle loading channel 39 through the needle feeding mechanism 2 to facilitate material unloading.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
