[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0045] A specific embodiment of this utility model provides a spring pressure testing and sorting device, combined with the attached... Figure 1 As shown, the system mainly includes a screening and feeding mechanism 1, a measuring mechanism 2, a sorting mechanism 3, and a conveying mechanism 4. The screening and feeding mechanism 1, the measuring mechanism 2, and the sorting mechanism 3 are arranged sequentially along the conveying direction of the conveying mechanism 4. The screening and feeding mechanism 1 is located at one end of the conveying mechanism 4. The screening and feeding mechanism 1 is used to feed the conveyed springs and screen them by their outer diameter. The measuring mechanism 2 is used to perform pressure tests on the springs after the initial outer diameter screening. The sorting mechanism 3 performs fine sorting based on the test structure of each spring during the pressure test. This arrangement allows the springs to flow between the various mechanisms through the conveying mechanism, and the outer diameter screening of the springs is achieved through the screening and feeding mechanism. Then, the pressure test is performed through the measuring mechanism, and finally, the sorting mechanism achieves the final sorting, which can effectively improve the detection efficiency and detection accuracy.

[0046] In specific embodiments of this application, in conjunction with the appendix Figure 2 and attached Figure 3 The screening and feeding mechanism 1 includes a feeding component 5, a screening component 6, a discharging component 7, and a transition component 8.

[0047] The feeding component 5 is located on one side of the screening component 6. The feeding component 5 is used to clamp and feed the springs that are conveyed. The feeding component 5 includes a clamping station and a discharging station. When the feeding component 5 is in the clamping station, it is close to the conveyor belt. The discharging station of the feeding component 5 is located above the screening station of the screening component 6. The screening component 6 is used to screen the outer diameter of the springs. The screening component 6 includes a screening station and a discharge station. When the screening component 6 is in the screening station, it is located below the discharge station of the feeding component 5. The discharge component 7 is located above the discharge station of the screening component 6. The discharge component 7 is used to push down the springs with unqualified outer diameters from the discharge component 7. The transition component 8 is located below the screening station of the screening component 6. The transition component 8 is used to carry the springs that have been screened by the screening component 6, so that the subsequent conveying mechanism can transport them to the next process.

[0048] In specific embodiments of this application, in conjunction with the appendix Figures 2-5As shown, the feeding assembly 5 includes a feeding motor 501, a feeding rod 502, a toggle block 503, an intermediate support block 504, a material-picking gripper cylinder 505, a longitudinal slide rail 506, a transverse slide rail 507, and a connecting slider 508; there are two first support plates 9 arranged in parallel, the feeding motor 501 is located on the outside of one of the first support plates 9, and the feeding rod 502 is rotatably arranged between the two parallel first support plates 9. The output shaft of the feeding motor 501 is connected to one end of the feeding rod 502. Machine 501 can drive the feeding rod 502 to rotate. One end of the actuating block 503 is fixedly connected to the feeding rod 502. There are two actuating blocks 503, which are respectively set near the two ends of the feeding rod 502. The actuating block 503 is also provided with a waist-shaped groove 10. The first support plate 9 is provided with a limit groove 11. The limit groove 11 is a curved groove. Both ends of the intermediate support block 504 pass through the waist-shaped groove 10 and are slidably connected to the limit groove 11. Bearings can be set at both ends of the intermediate support block 504, and the bearings are located in the waist-shaped groove 10 and the limit groove. Within 11, a sliding connection between it and the two slots is achieved. A material-grabbing claw cylinder 505 is set at the middle position of the intermediate support block 504. The number of material-grabbing claw cylinders 505 can be multiple, capable of simultaneously gripping multiple springs. Both ends of the intermediate support block 504 near the two actuating blocks 503 are connected to longitudinal slide rails 506. A transverse slide rail 507 is set on the first support plate 9. The longitudinal slide rail 506 and the transverse slide rail 507 are slidably connected by a connecting slider 508. Vertical sliding rails are respectively set on the two end faces of this connecting slider 508. The groove and horizontal slide are used to limit and slide with the longitudinal slide rail 506 and the transverse slide rail 507 respectively. In this technical solution, when the feeding rod 502 is driven to rotate by the feeding motor 501, it will drive the actuating block 503 to swing. Due to the arrangement of the longitudinal slide rail 506, the transverse slide rail 507 and the connecting slider 508, the intermediate support block 504 and the picking claw cylinder 505 on it maintain the state of translation, thereby realizing the reciprocating movement between the picking station and the unloading station, and thus realizing the reciprocating gripping of the spring.

[0049] In some embodiments, in conjunction with the appendix Figure 2 , 3As shown in Figure 6, the screening component 6 includes a feeding motor 601, a feeding rod 602, feeding blocks 603, a screening block 604, and a screening barrel 605. The feeding motor 601 is located on the outside of one of the first support plates 9. The two ends of the feeding rod 602 are rotatably connected to the two first support plates 9. The output shaft of the feeding motor 601 is connected to the feeding rod 602, and the feeding motor 601 can drive the rotation of the feeding rod 602. There are two feeding blocks 603, which are respectively located near the two ends of the feeding rod 602. The screening block 604 is located between the two feeding blocks 603. The screening barrel 605 is located on the screening block 604. The screening barrel 605 is a cylindrical body that runs vertically through the screen. The screening barrel 605 has different opening sizes in the upper and lower directions, forming an annular step inside. This restricts the passage of oversized, unqualified springs, while allowing qualified springs to pass through. The feeding motor 601 drives the screening barrel 605 to reciprocate from a screening station with the placement opening facing upwards to a feeding station with the placement opening facing downwards. The inner diameter of the placement opening is larger than the inner diameter of the outlet at the other end. At the screening station, the placement opening faces upwards to receive springs falling from the feeding assembly 5. The rotation of the feeding motor 601 drives the feeding rod 602 to rotate, which in turn moves the feeding block 603 and the screening block 604, causing the screening barrel 605 to rotate 180°. There are multiple screening barrels 605, each corresponding to a different gripper cylinder 505.

[0050] In some embodiments, in conjunction with the appendix Figure 2 , 3 As shown in Figures 7 and 8, the feeding assembly 7 includes a feeding profile 701, a feeding plate 702, a feeding cylinder 703, and a feeding trough 704. There are two second support plates 12, which surround the two first support plates 9 in a square shape. There are two feeding profiles 701, which are arranged parallel to each other between the two second support plates 12. The feeding plate 702 is arranged between the two feeding profiles 701. The feeding cylinder 703 is arranged on the feeding plate 702 and is located above the feeding station of the screening assembly 6. The feeding trough 704 is located below the feeding station of the screening assembly 6. The driving end of the feeding cylinder 703 is located below the feeding plate 702, and the driving end of the feeding cylinder 703 can pass through the screening barrel 605 of the screening assembly 6 in the feeding state, and push down the unqualified spring in the screening barrel 605 and make it fall into the feeding trough 704 below.

[0051] In some embodiments, in conjunction with the appendix Figure 2 , 3As shown in Figures 7 and 8, the transition component 8 includes a connecting plate 801, a connecting slide rail 802, a transition slider 803, a transition plate 804, a feeding rotary cylinder 805, a transition cylinder 806, a discharging plate 807, a connecting rod 808, a discharging block 809, and a limiting cylinder 810. The connecting plate 801 is provided with two connecting slide rails 802 arranged in parallel. Transition sliders 803 are provided on the connecting slide rails 802, with two sliders 803 on the same connecting slide rail 802. A transition slider 803 is slidable along a connecting slide rail 802. A transition plate 804 is provided on the transition slider 803, and the transition plate 804 is connected to two corresponding transition sliders 803 on the two connecting slide rails 802. There are two transition plates 804, and each transition plate 804 is provided with a feeding rotary cylinder 805. The transition plate 804 is connected to a transition cylinder 806 provided on a connecting plate 801, and the transition cylinder 806 can drive the two transition plates 804 to move closer to each other. Alternatively, they can be positioned far apart, with the feeding plate 807 located above the connecting plate 801. The feeding plate 807 and the connecting plate 801 are connected by a connecting rod 808. The feeding plate 807 is provided with a feeding cavity 13, and the feeding block 809 is located inside the feeding cavity 13. The feeding block 809 is connected to a feeding rotary cylinder 805, which can drive the feeding block 809 to rotate. A limiting cylinder 810 is located below the feeding block 809, and the limiting end of the limiting cylinder 810 can pass through the feeding block 809. The 9th cylinder extends above the feeding block 809. A limiting cylinder 810 is used to restrict the springs passing through the screening component 6. There are multiple limiting cylinders 810. In a specific embodiment of this application, three limiting cylinders 810 are provided at each feeding block 809, resulting in a total of six limiting cylinders 810 at two feeding blocks 809. This number is the same as the number of screening barrels 605 and material-picking gripper cylinders 505. The limiting cylinders 810 on each feeding block 809 are arranged side-by-side. The rotation of the feeding rotary cylinder 805 can drive the feeding block 809 to rotate, thus allowing the six limiting cylinders 810 on the two feeding blocks 809 to be arranged side-by-side. This corresponds to the arrangement of the material-picking gripper cylinders 505, which is used to support the falling springs. The rotation of the feeding rotary cylinder 805 can also arrange the springs in a row, forming two rows of three each. This arrangement is intended to correspond to the conveying mechanism 4.

[0052] In some embodiments, in conjunction with the appendix Figure 9 and attached Figure 10As shown, the measuring mechanism 2 includes a measuring base 201, a connecting rod 202, a measuring plate 203, a pressure sensor 204, a measuring top plate 205, and a downward pressing electric cylinder 206. The measuring plate 203 is mounted on the measuring base 201 via the connecting rod 202. The pressure sensors 204 are mounted on the measuring plate 203. There are multiple pressure sensors 204, specifically six, corresponding to the number of limit cylinders 810 on the transition assembly 8. The measuring top plate 205 is positioned above the pressure sensors 204, and the downward pressing electric cylinder 206 is mounted on the measuring top plate 205. A downward pressing plate 14 is positioned at the bottom of the downward pressing electric cylinder 206, facing the pressure sensor 204. The downward pressing plate 14 is driven downward by the downward pressing electric cylinder 206 to apply pressure to the spring. The pressure sensor 204 then measures the elastic force of the spring at its position for reference during the fine sorting at the next workstation.

[0053] In some embodiments, in conjunction with the appendix Figure 11 and attached Figure 12 As shown, the sorting mechanism 3 includes a support block 301, a support rod 302, a belt conveyor 303, and a sorting cylinder 304. The support block 301 is mounted on the base plate 15 via the support rod 302. The belt conveyor 303 is positioned below the support block 301. The support block 301 has a material passage hole 306 through which a spring can fall. The sorting cylinder 304 is positioned below the support block 301, and a sorting block 305 is mounted at the output end of the sorting cylinder 304. The sorting block 305 is slidable. Set on the material passage 306, the sorting cylinder 304 can drive the sorting block 305 on the corresponding material passage 306 to move. The number of sorting cylinders 304 is the same as the number of material passages 306 and they are set one-to-one. There are multiple material passages 306, and there are six material passages 306, which correspond to the arrangement of pressure sensors 204. The number of sorting cylinders 304 is also six. In this way, the spring that conforms to the setting of the sorting mechanism 3 can fall at this sorting mechanism 3.

[0054] The specific sorting mechanism 3 is multiple and arranged sequentially along the conveying direction of the conveying mechanism 4. Different sorting mechanisms 3 sort springs with different performance ranges, thus achieving more precise sorting.

[0055] It should be noted that each sorting mechanism 3 has six sorting cylinders 304, which are the same as those at the pressure sensor 204. In this way, the spring performance measured at the corresponding position from the pressure sensor 204 can fall from the corresponding sorting mechanism 3 and be transported down by the belt conveyor 303.

[0056] In specific embodiments of this application, in conjunction with the appendix Figure 1 Appendix Figure 13 and attached Figure 14As shown, the conveying mechanism 4 includes a third support plate 401, a conveying support rod 402, a feeding rotary cylinder 403, a feeding tray 404, a vertical rod 405, a limiting slide rail 406, a limiting slider 407, a fixing block 408, a rotating rod 409, a connecting push rod 410, a transverse block 411, a transverse slider 412, a transverse slide rail 413, a fixing plate 414, a fixing rod 415, a connecting profile 416, a feeding plate 417, a slide cylinder 418, and a lever 419.

[0057] The third support plate 401 is mounted on the base plate 15 via a conveying support rod 402. A feeding rotary cylinder 403 is mounted on the third support plate 401, and a feeding disc 404 is mounted on the top of the feeding rotary cylinder 403. The feeding disc 404 has an arc-shaped outer push cavity 16 extending from the center to the edge. A vertical rod 405 is slidably mounted inside the outer push cavity 16. The bottom of the vertical rod 405 is connected to one end of a limiting slide rail 406. A fixing block 408 is mounted on the other end of the limiting slide rail 406. The limiting slide rail 406 is slidably mounted on the third support plate 401 via a limiting slider 407. Both ends of the fixing block 408 are hinged to a connecting push rod 410 via a rotating rod 409. The end of the connecting push rod 410 away from the fixing block 408 is connected to a transverse block 41. 1. A hinged joint is formed. The transverse block 411 is mounted on the transverse slide rail 413 via the transverse slider 412. The transverse slide rail 413 is mounted on the fixed plate 414. The fixed plate 414 is mounted on the base plate 15 via the fixed rod 415. The bottom of the transverse block 411 is slidably connected to the connecting profile 416 via the fixed slider. The bottom of the connecting profile 416 is provided with multiple feeding plates 417. The feeding plates 417 are provided with multiple spring receiving grooves. The bottom of the third support plate 401 is provided with a slide cylinder 418. The driving end of the slide cylinder 418 is provided with a lever 419. The lever 419 is provided with a slot 17 perpendicular to the length direction of the connecting profile 416. The connecting profile 416 is provided with a limiting rod 18, which is slidably mounted in the slot 17.

[0058] The rotation of the feeding rotary cylinder 403 drives the feeding disc 404 to rotate, which in turn drives the upright 405 to move through the outer push cavity 16. The movement of the upright 405 causes the limiting slide rail 406 to translate along the limiting slider 407. The translation of the limiting slide rail 406 will push the transverse block 411 to move through the connecting push rod 410. The transverse block 411 can achieve horizontal translation through the transverse slide rail 413 and the transverse slider 412. Since the bottom of the transverse block 411 is slidably connected to the connecting profile 416 through the fixed slider, and the direction of the fixed slider is the same as the direction of the limiting slide rail 406, the translation of the transverse block 411 will drive the translation of the connecting profile 416 at its bottom. Since the two transverse blocks 411 move closer or further away from each other, they will cause the connecting profile 416 at the bottom to move closer or further away from each other, which will indirectly cause the feeding plate 417 to move closer or further away from each other.

[0059] It should be noted that the following mechanisms are provided on both sides of the feeding tray 404: limiting slide rail 406, limiting slider 407, fixing block 408, rotating rod 409, connecting push rod 410, transverse block 411, transverse slider 412, transverse slide rail 413, fixing plate 414, and fixing rod 415; in this way, the connecting profiles 416 can be driven to move away from or towards each other from both ends, thereby driving the multiple sets of feeding plates 417 at their bottom to move away from or towards each other.

[0060] Furthermore, the arrangement of the slide cylinder 418 and the toggle block 419 can drive the connecting profile 416 and the feeding plate 417 to move left or right.

[0061] Thus, this application achieves clamping and translational conveying through the aforementioned conveying mechanism 4.
