Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] A spring mounting detection mechanism, such as Figure 1 As shown, it includes a table 1, a detection component 2 is fixedly mounted on the table 1, a feeding mechanism 4 is mounted on the table 1 and located on one side of the detection component 2, and a feeding fixture 3 is mounted on one side of the table 1.

[0022] like Figure 2 , Figure 3 As shown, the detection component 2 includes a frame 20, on which a pen-shaped cylinder 21 is fixedly mounted. The output end of the pen-shaped cylinder 21 is connected to a slide plate 22. The slide plate 22 slides vertically on one side of the frame 20. A micrometer head 23 is mounted on the slide plate 22. A pressure sensor 25 is located below the micrometer head 23. A laser sensor 24 is located on the front side of the micrometer head 23. When the laser sensor 24 is located directly above the loading fixture 3, it can detect the parts on the loading fixture 3. The pressure sensor 25 and the laser sensor 24 are a type of smart sensor.

[0023] A pressure column 26 is connected to the front of the input end of the pressure sensor 25, and a pressure probe 27 is connected to the bottom of the pressure column 26. The pressure probe 27 contacts the spring 32 to test the elastic force of the spring 32 when it is compressed, so that the pressure sensor 25 can monitor the generated pressure.

[0024] like Figure 4 , Figure 5 , Figure 6 As shown, a base 11 is provided below the platform 1. A guide trough 12 is fixedly installed on one side of the base 11. A push cylinder is provided at one end of the guide trough 12 (not shown in the figure). The push cylinder pushes one end of the feeding fixture 3, moving the feeding fixture 3 to slide within the guide trough 12.

[0025] A motor 14 is bolted to the base 11. The output end of the motor 14 is connected to a threaded rod 15. A guide rod 17 is arranged parallel to the threaded rod 15. A push plate 19 is slidably mounted on the guide rod 17. A round shaft 16 is fixedly connected to the bottom of the push plate 19. The lower end of the round shaft 16 is slidably connected to the threaded groove on the outer circumference of the threaded rod 15. The motor 14 drives the threaded rod 15 to rotate, converting the rotational motion of the threaded rod 15 into the horizontal motion of the round shaft 16.

[0026] A reset spring 18 is fitted on the guide rod 17. The reset spring 18 is connected to one side of the push plate 19. A limit block 10 is fixed on one side of the push plate 19. A through groove 13 is opened on one side of the guide groove 12. The through groove 13 is slidably connected to the limit block 10. After the limit block 10 passes through the through groove 13, it limits and fixes the feeding fixture 3, preventing the feeding fixture 3 from moving in the guide groove 12 and stabilizing it below the laser sensor 24.

[0027] like Figure 7 , Figure 8 As shown, two material slots 30 are provided on the feeding fixture 3, and two grooves 301 are provided in each material slot 30. A positioning fixture 302 is provided in the groove 301 of one material slot 30, and the product 31 is installed on the positioning fixture 302. A spring fixture 303 is provided in the groove 301 of the other material slot 30. The spring fixture 303 is provided with two protrusions to fix the spring 32 on it and position the spring 32.

[0028] During testing, the product 31 and spring 32 are first manually placed into the two material slots 30 of the loading fixture 3, and then the entire loading fixture 3 is placed into the guide groove 12. The cylinder is pushed to move the loading fixture 3. When it moves to the position of the limit block 10, the motor 14 starts and drives the threaded rod 15 to rotate. The rotation of the threaded rod 15 drives the round shaft 16 to move along the threaded groove, thereby pushing the push plate 19 to slide along the guide rod 17, so that the limit block 10 passes through the through groove 13 to block and limit the loading fixture 3. At this time, one of the material slots 30 on the loading fixture 3 moves directly below the laser sensor 24 and the pressure probe 27.

[0029] Laser sensor 24 first detects the workpiece in the material trough 30 to identify whether spring 33 is installed backwards or missing. If the detection fails, the equipment issues an alarm, and the defective product is manually removed and reloaded. If the detection passes, pen-shaped cylinder 21 starts and drives slide plate 22 to move downwards, so that pressure probe 27 contacts spring 32. Micrometer head 23 precisely controls the downward pressing distance, and pressure sensor 25 collects pressure data in real time during the pressing process to complete the detection of spring force of spring 32. After the detection is completed, pen-shaped cylinder 21 drives slide plate 22 to reset, motor 14 reverses, threaded rod 15 rotates in the opposite direction, and push plate 19 drives limit block 10 to retract under the elastic force of reset spring 18, releasing the limit on loading fixture 3. Push cylinder continues to push the next loading fixture 3 into the trough. The loading fixture 3 that has completed the detection is pushed out of guide trough 12, and the unloading is completed. Then, the new loading fixture 3 moves to the detection position and repeats the above detection process to achieve continuous detection operation.

[0030] like Figures 9-11 As shown, the feeding mechanism 4 includes a flat plate 41, on which two support bars 42 are fixedly mounted. One end of each support bar 42 is fixedly mounted with an inclined surface 44. A horizontal groove 43 is provided on the side of the support bar 42. A guide shaft 402 is horizontally slidably mounted in the horizontal groove 43. A movable plate 401 is mounted on the support bar 42. The lower end of the movable plate 401 is fastened to the guide shaft 402, and the guide shaft 402 guides the movable plate 401.

[0031] Two parallel guide rails 404 are provided on the front side of the movable plate 401. A pressure shaft 403 is provided between the two guide rails 404. A support plate 45 is slidably mounted on the two guide rails 404. The pressure shaft 403 is slidably connected to the support plate 45. A compression spring is fitted on the pressure shaft 403. The lower end of the compression spring is connected to the support plate 45. When the support plate 45 moves upward along the guide rails 404, the support plate 45 moves upward along the pressure shaft 403, compressing the compression spring and shortening its length to store the spring force.

[0032] A servo cylinder 40 is fixedly installed on the top of the plate 41 by bolts. The output end of the servo cylinder 40 is connected to the moving plate 401. The servo cylinder 40 moves the moving plate 401 and controls the movement of the support plate 45 at the same time.

[0033] A sliding block 451 is fixedly installed at the lower end of the pallet 45. The sliding block 451 is slidably connected to the support bar 42 and the inclined surface 44. When the sliding block 451 slides on the support bar 42, it is in a horizontal movement state. When the sliding block 451 slides along the inclined surface 44, it is in a sliding state along the inclined surface 44, changing the height of the pallet 45.

[0034] A stand is fixedly installed on the pallet 45. A second motor 46 is fixedly installed at the top of the stand. A cylinder seat 461 is fixedly connected to the output end of the second motor 46. A picking cylinder 47 is installed on the cylinder seat 461 by bolts. A clamp 471 is connected to the output end of the picking cylinder 47. The clamp 471 is used to pick up and put down the product 31 and the spring 32 by clamping.

[0035] A top frame 48 is fixedly mounted on the flat plate 41. A motor 3 480 is fixedly mounted on the top of the top frame 48. A motor 4800 is mounted on the front end of the top frame 48. A gear 1 4801 is fixedly mounted on the output end of the motor 4800. A fixture slot is opened on the top of the top frame 48. A U-shaped fixture 4804 is rotatably mounted in the fixture slot. A clamping cylinder 4803 is fixedly mounted on one end of the U-shaped fixture 4804. The output end of the clamping cylinder 4803 passes through the U-shaped fixture 4804 to clamp the product 31 located in the middle of the U-shaped fixture 4804. A gear 2 4802 is fixedly mounted on the end of the U-shaped fixture 4804. The gear 2 4802 cooperates with the gear 1 4801 to transmit power, so that the motor 4800 can control the rotation of the U-shaped fixture 4804 to complete the direction switching of the product 31.

[0036] A mounting plate 49 is fixedly connected to the output end of motor 3 480. A detection rod 491 is slidably mounted on the mounting plate 49. A straight groove 492 is opened on the detection rod 491. Motor 5 490 is fixedly mounted on the mounting plate 49. A swing arm 493 is fixedly connected to the output end of motor 5 490. One end of the swing arm 493 is connected to a pressure rod 494. Both ends of the pressure rod 494 are slidably connected to the straight groove 492. A sliding groove 495 is opened on the pressure rod 494. A driven shaft is slidably mounted in the sliding groove 495. An air bag 496 is set below the driven shaft. An intelligent pressure sensor is set in the air bag 496. When the driven shaft moves downward, the gas in the air bag 496 is compressed. The intelligent pressure sensor monitors the change in air pressure to monitor the downward pressure of the detection rod 491.

[0037] The detection rod 491 moves downward to test the product 31 located in the U-shaped fixture 4804, and to test the compressive strength of the product 31.

[0038] Once spring 32 passes inspection, the feeding mechanism 4 will load and unload product 31 and spring 32. The manually loaded product 31 and spring 32 will be inspected and reversed. If product 31 and spring 32 are incorrectly loaded, the feeding mechanism 4 can be moved to the U-shaped fixture 4804. The U-shaped fixture 4804 will flip product 31 or spring 32, and after adjustment, it will be installed on the feeding fixture 3.

[0039] Specific operation: The picking cylinder 47 drives the clamp 471 to first pick up the product 31 to be assembled from the loading fixture 3 and move it into the U-shaped fixture 4804. After the clamp cylinder 4803 clamps the product 31, the motor 490 drives the swing arm 493 to rotate. The swing arm 493 drives the pressure rod 494 to press down the detection rod 491 to complete the pressure resistance test of the product 31. If the test fails, the defective product is rejected; if the test passes, the motor 4800 drives the gear 4801 to rotate. The meshing gear 4802 drives the U-shaped fixture 4804 to rotate, rotating the product 31 to the appropriate and correct assembly angle. Then, the picking cylinder 47 picks up the qualified spring 32 and moves it to the loading fixture 3. The product 31 is then installed into the corresponding mounting position on the loading fixture 3. After the assembly is completed, the clamping cylinder 4803 releases the assembled workpiece, which is then removed by the loading fixture 3, completing one assembly and inspection process. Afterward, the loading mechanism is reset to prepare for the next loading operation.
