However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0046] like Figure 1-8 As shown, a pin assembly machine includes a chassis 1, a fixture feeding device 2, a worktable 3, a positioning and moving device 4, a pin feeding device 5, an assembly device 6, a correction device 7, and a unloading device 8. The chassis 1 is vertically arranged. The fixture feeding device 2 is located on the left side of the top surface of the chassis 1. The worktable 3 is located on the top surface of the chassis 1, to the right of the fixture feeding device 2. The positioning and moving device 4 is located on the top surface of the chassis 1, to the rear of the worktable 3. The pin feeding device 5 and the assembly device 6 are located on the top surface of the chassis 1, to the front and rear sides of the worktable 3. The correction device 7 is located on the top surface of the chassis 1, to the rear of the worktable 3 and to the right of the positioning and moving device 4. The unloading device 8 is connected to the right end of the worktable 3. The jig loading device 2 loads the jig containing the magnetic ring, the positioning and moving device 4 moves the loaded jig to the worktable 3, and at the same time the pin loading device 5 loads the pins. Then, the assembly device 6 assembles the pins into the magnetic ring on the worktable 3. After assembly, the jig moves to the bottom of the correction device 7, the correction device 7 corrects the assembled pins, and finally the unloading device 8 unloads the jig.

[0047] like Figure 2 As shown, the fixture feeding device 2 includes a belt conveyor 21; the belt conveyor 21 is horizontally mounted on the top surface of the machine housing 1; the workbench 3 includes a base 31 and a feeding platform 32; the base 31 is horizontally mounted on the top surface of the machine housing 1; the feeding platform 32 is horizontally mounted on the top surface of the base 31, with its left end connected to the right end of the belt conveyor 21, and a channel for the fixture to move is provided on its top surface; after the fixture is fed by the belt conveyor 21, it is moved to the channel of the feeding platform 32 by the positioning and moving device 4, and the magnetic ring on the fixture is assembled, corrected and unloaded on the feeding platform 32.

[0048] like Figure 3As shown, the positioning and moving device 4 includes support legs 41, a left-right moving module 42, a right-right moving module 43, a positioning plate 44, and a positioning rod 45. The support legs 41 are vertically arranged and two are spaced apart on the left and right sides. The left-right moving module 42 is horizontally arranged, and its two ends are connected to the upper part of the opposite side of the two support legs 41. The right-right moving module 43 is vertically arranged and connected to the left-right moving module 42. The left-right moving module 42 can drive the right-right moving module 43 to move left and right. The upper part of the rear side of the positioning plate 44 is connected to the right-right moving module 43. The right-right moving module 43 can drive the positioning plate 44 to move up and down. The positioning rod 45 is vertically arranged on the left and right sides of the bottom of the positioning plate 44, and its bottom end extends downward. After the fixture is in place, the left-right moving module 42 drives the up-down moving module 43 and the positioning rod 45 to move to the left above the fixture. Then, the up-down moving module 43 drives the positioning rod 45 to descend, so that the two positioning rods 45 are inserted into the positioning holes of the fixture. Then, the left-right moving module 42 drives the positioning rod 45 to move to the right, so that the fixture enters the channel of the feeding table 32. During the assembly process, the positioning moving device 4 drives the fixture to move to the right, and cooperates with the assembly device 6 to assemble the pins of all the magnetic rings on the fixture.

[0049] In a further embodiment, a loading infrared sensor is provided on the left side of the base 31 of the workbench 3. As the positioning and moving device 4 continuously drives the fixture to move to the right, a gap will be created between the previous fixture and the next fixture. When the loading infrared sensor senses the gap, that is, when there is no material at that position, the belt conveyor 21 starts to transport the next fixture to that position, so that the positioning and moving device 4 can position and move the next fixture. When the loading infrared sensor senses that there is material, the belt conveyor 21 stops transporting.

[0050] like Figure 1 , 4 As shown, the PIN feeding device 5 includes a front PIN feeding mechanism 51 and a rear PIN feeding mechanism 52. The front PIN feeding mechanism 51 is located on the front side of the workbench 3 and includes a linear vibrating feeder 511, a vibrating plate 512, and a feeding track 513. The linear vibrating feeder 511 is located in front of the workbench 3. The vibrating plate 512 is located on the right front of the linear vibrating feeder 511. One side of the feeding track 513 is located on the top surface of the linear vibrating feeder 511, and the other side is connected to the discharge end of the vibrating plate 512. The rear PIN feeding mechanism 52 is located on the rear side of the workbench 3. The rear PIN feeding mechanism 52 has the same structure as the front PIN feeding mechanism 51 and is arranged in a centrally symmetrical manner with the front PIN feeding mechanism 51. The vibratory feeders 512 of the front pin feeding mechanism 51 and the rear pin feeding mechanism 52 arrange the pins neatly, and the direct vibration feeder 511 feeds the pins from the vibratory feeder 512 through the feeding track 513.

[0051] In a further embodiment, the feeding track 513 is provided with a pin-type infrared sensor on the side near the worktable 3. When the pin-type infrared sensor senses that there is material at the end of the feeding track 513 near the worktable 3, the direct vibration feeder 511 and the vibrating plate 512 stop feeding. When it senses that there is no material, it starts feeding.

[0052] like Figure 1 , 5As shown in Figure 6, the assembly device 6 includes a front assembly mechanism 61 and a rear assembly mechanism 62. The rear assembly mechanism 62 includes a mounting platform 6201, left and right sliding cylinders 6202, a base plate 6203, a mounting plate 6204, a rotary motor 6205, a rotating plate 6206, a connecting plate 6207, a first upper and lower sliding cylinder 6208, a mounting block 6209, a connector 6210, and a suction nozzle 6211. The mounting platform 6201 is located behind the worktable 3. The left and right sliding cylinders 6202 are located on the top surface of the mounting platform 6201. The base plate 6203 is fixedly mounted on the top surface of the sliding cylinders 6202. The mounting plate 6204 is vertically mounted on the top surface of the base plate 6203, with two plates spaced apart. The rotary motor 6205 is vertically mounted on the rear side of the rear mounting plate 6204, and its output... The output shaft passes through the front side of the rear mounting plate 6204; the rotating plate 6206 is rotatably mounted on the front side of the front mounting plate 6204, and its rear side is connected to the rotary motor 6205 for transmission; the connecting plate 6207 is fixedly mounted on the front side of the rotating plate 6206; the first upper and lower sliding table cylinder 6208 is vertically mounted on the front side of the connecting plate 6207; the mounting block 6209 is fixedly mounted on the front side of the sliding table of the first upper and lower sliding table cylinder 6208; the connecting piece 6210 is vertically mounted on the front side of the mounting block 6209; the suction nozzle 6211 is vertically mounted on the connecting piece 6210, and its bottom end extends downward. The suction nozzle 6211 is externally connected to a vacuum generator; the front assembly mechanism 61 is located on the front side of the workbench 3. The front assembly mechanism 61 has the same structure as the rear assembly mechanism 62 and is centrally symmetrical with the rear assembly mechanism 62. After the PIN is in place, the first upper and lower sliding table cylinder 6208 drives the suction nozzle 6211 to move downward, so that the suction nozzle 6211 picks up the PIN. Then, the rotary motor 6205 drives the first upper and lower sliding table cylinder 6208 and the suction nozzle 6211 to rotate 90°, so that the suction nozzle 6211 holding the PIN rotates to the position where the PIN needs to be assembled on the corresponding magnetic ring. At the same time, the left and right sliding table cylinders 6202 are activated, driving the suction nozzle 6211 to move towards the magnetic ring, so that the PIN is assembled on the magnetic ring. After assembly, the suction nozzle 6211 releases the magnetic ring, completing the PIN assembly. The front assembly mechanism 61 and the rear assembly mechanism 62 work synchronously to realize the assembly of the PINs on both sides of a single magnetic ring. After the PINs of a single magnetic ring are assembled, the left and right sliding table cylinders 6202, the rotary motor 6205, and the first upper and lower sliding table cylinder 6208 are reset. The positioning and moving device 4 moves the fixture to the right to assemble the next magnetic ring, until all the magnetic rings on a fixture are assembled.

[0053] In a further embodiment, the rear assembly mechanism 62 includes bearing seats in the middle of the mounting plates 6204 on both the front and rear sides. The output shaft of the rotary motor 6205 passes through the bearing seat of the rear mounting plate 6204 to the front side of the mounting plate 6204. It also includes a rotating shaft housed within the bearing seat of the front mounting plate 6204. One end of the rotating shaft is fixedly connected to the rear side of the rotating plate 6206, and the other end is connected to the output shaft of the rotary motor 6205 via a coupling. The output shaft of the rotary motor 6205 rotates on the rear connecting plate, driving the rotating shaft to rotate via the coupling. The rotating shaft then drives the rotating plate 6206 to rotate, thus rotating the suction nozzle 6211.

[0054] like Figure 2 , 7 As shown, the correction device 7 includes a correction mechanism 71; the correction mechanism 71 includes a vertical plate 711, a second upper and lower sliding table cylinder 712, a finger cylinder 713, and a clamp 714; the vertical plate 711 is vertically arranged on the top surface of the platform 31, located behind the feeding table 32; the second upper and lower sliding table cylinder 712 is vertically arranged on the upper part of the front side of the vertical plate 711; the finger cylinder 713 is vertically arranged with its fingers located below, and the top surface of the finger cylinder 713 is fixedly connected to the bottom surface of the sliding table of the second upper and lower sliding table cylinder 712; two clamps 714 are provided, respectively arranged on the front side of the two fingers of the finger cylinder 713. After all the magnetic rings on the fixture are assembled, the fixture moves to the bottom of the correction device 7. The second upper and lower sliding stage cylinder 712 of the correction mechanism 71 drives the finger cylinder 713 and the clamp 714 to move downward. After they are in place, the finger cylinder 713 is activated, causing its two fingers to move relative to each other, which in turn drives the clamp 714 to move relative to each other, so that the clamp 714 presses the two pins of the magnetic ring. Then the second upper and lower sliding stage cylinder 712 drives the clamp 714 to move upward, thereby correcting the misassembly of the pins during the assembly process, such as tilting or not being tightly attached to the magnetic ring.

[0055] like Figure 2 , 8The correction device 7 shown also includes a fixing mechanism 72; the fixing mechanism 72 includes a vertical plate 721, a fixing plate 722, a cylinder seat 723, a pressing cylinder 724, and a pressing rod 725; the vertical plate 721 is vertically arranged on the top surface of the platform 31, located behind the feeding platform 32, and on the left side of the correction mechanism 71; the fixing plate 722 is vertically arranged on the rear side of the vertical plate 721; the cylinder seat 723 is vertically arranged on the top surface of the fixing plate 722; the pressing cylinder 724 is vertically arranged on the top surface of the cylinder seat 723, and its piston rod passes downward through the cylinder seat 723; the pressing rod 725 is vertically arranged, and its top end is connected to the bottom end of the piston rod of the pressing cylinder 724. When the fixture moves to below the correction device 7, the piston rod of the pressing cylinder 724 of the fixing mechanism 72 extends, driving the pressure rod 725 to move downward, so that the pressure rod 725 presses down on the magnetic ring, thereby fixing the magnetic ring and preventing the magnetic ring from moving when the correction mechanism 71 clamps, thus ensuring stability during the correction process.

[0056] like Figure 7 As shown, the clamp 714 and the finger of the finger cylinder 713 are slidably connected via a slide table and a slide rail; the correction mechanism 71 also includes a floating buffer mechanism 73; the floating buffer mechanism 73 includes a fixing block 731, a connecting rod 732, an upper guide block 733, a lower guide block 734, a limiting block 735, and a spring 736; the fixing block 731 is fixedly connected to the left side of the cylinder body of the finger cylinder 713, and its top and bottom surfaces are provided with vertically penetrating sliding grooves; two connecting rods 732 are vertically arranged, and the bottom ends of the two connecting rods 732 are respectively connected to two... The top surface of the clamp 714 is fixedly connected, and its top end passes through the groove of the fixing block 731 and extends upward. The upper guide block 733 is respectively sleeved on the upper part of the two connecting rods 732 and is located above the fixing block 731. The lower guide block 734 is respectively sleeved on the two connecting rods 732 and is located below the fixing block 731. The limiting block 735 is respectively fixedly installed on the top of the two connecting rods 732. The spring 736 is respectively sleeved on the connecting rod 732, with one end connected to the bottom surface of the upper guide block 733 and the other end connected to the bottom end of the limiting block 735. During correction, since the second upper and lower sliding table cylinder 712 will drive the clamp 714 to move upward, the PIN will be subjected to a large force, which may cause the PIN to deform. Therefore, by setting a floating buffer mechanism 73, the force on the PIN can be reduced when the clamp 714 moves upward, preventing the PIN from deforming.

[0057] like Figure 2As shown, the unloading device 8 includes an unloading slide cylinder 81 and a push plate 82. The unloading slide cylinder 81 is horizontally positioned on the top surface of the base 31, located behind the feeding table 32. The push plate 82 is horizontally positioned at the front end of the slide of the unloading slide cylinder 81. After correction, the fixture moves to the corresponding position of the unloading device 8, the piston rod of the unloading slide cylinder 81 extends, driving the push plate 82 to move forward, pushing out the fixture, and realizing unloading.

[0058] like Figure 2 As shown, the feeding device 8 also includes a receiving plate 83; the receiving plate 83 is disposed on the front side of the feeding table 32 corresponding to the push plate 82. After the fixture is pushed forward by the feeding slide cylinder 81 and the push plate 82, it enters the receiving plate 83 for storage, which is convenient for collection.

[0059] The working principle of this utility model is as follows:

[0060] The fixture carrying the magnetic ring is fed by the belt conveyor 21 of the feeding device. After reaching its position, the left-right moving module 42 of the positioning and moving device 4 drives the up-down moving module 43 and the positioning rod 45 to move to the left above the fixture. Then, the up-down moving module 43 drives the positioning rod 45 to descend, so that the two positioning rods 45 are inserted into the positioning holes of the fixture. Then, the left-right moving module 42 drives the positioning rod 45 to move to the right, so that the fixture enters the channel of the feeding table 32. The direct vibration feeder 511 of the front PIN feeding mechanism 51 and the rear PIN feeding mechanism 52 feeds the PINs from the vibratory plate 512 through the feeding track 513.

[0061] After the fixture and pins are in place, the front assembly mechanism 61 and the rear assembly mechanism 62 of the assembly device 6 operate synchronously. The first upper and lower sliding table cylinder 6208 drives the suction nozzle 6211 to move downward, so that the suction nozzle 6211 picks up the pin. Then, the rotary motor 6205 drives the first upper and lower sliding table cylinder 6208 and the suction nozzle 6211 to rotate 90°, so that the suction nozzle 6211 holding the pin is aligned with the position of the magnetic ring where the pin needs to be assembled. At the same time, the left and right sliding table cylinders 6202 are activated, driving the suction nozzle to move towards the magnetic ring, so that the pin is assembled into the magnetic ring. On the ring, after assembly, the suction nozzle 6211 releases the magnetic ring, completing the pin assembly of the first magnetic ring (counting from right to left) in the fixture; then the front assembly mechanism 61 and the rear assembly mechanism 62 reset, the pin feeding device 5 continues to feed the pins, and at the same time the positioning and moving device 4 moves the fixture to the right, so that the second magnetic ring moves to the position corresponding to the front assembly mechanism 61 and the rear assembly mechanism 62. The front assembly mechanism 61 and the rear assembly mechanism 62 continue to assemble the pins onto the second magnetic ring, and so on, to complete the pin assembly of all magnetic rings on the first fixture.

[0062] After all the magnetic rings on the first fixture are assembled, the positioning and moving device 4 resets and continues to move the second fixture to the worktable 3. When the positioning and moving device 4 moves the second fixture, the second fixture will contact the first fixture, causing the second fixture to push the first fixture to the right, so that the first fixture moves to below the correction device 7. The fixing mechanism 72 of the correction device 7 is activated, the piston rod of the pressing cylinder 724 extends, driving the pressure rod 725 to move downward, so that the pressure rod 725 presses the magnetic ring and fixes the magnetic ring. Then, the second upper and lower sliding stage cylinder 712 of the correction mechanism 71 drives the finger cylinder 713 and the clamp 714 to move downward. The finger cylinder 713 is activated, causing its two fingers to move relative to each other, driving the clamp 714 to move relative to each other, thereby pressing the two pins of the magnetic ring. Then, the second upper and lower sliding stage cylinder 712 drives the clamp 714 to move upward, thereby correcting the misassembly of the pins during the assembly process, such as tilting or not being tightly attached to the magnetic ring. As the positioning and moving device 4 works with the assembly device 6 to assemble the pins of the magnetic rings on the second fixture, it continuously drives the second fixture to move to the right, causing the magnetic rings on the second fixture to move sequentially to the positions corresponding to the assembly device 6. Therefore, the second fixture will push the first fixture to move continuously to the right, so that the magnetic rings on the first fixture will sequentially correspond to the correction device 7, thereby completing the pin correction work of all the magnetic rings on the first fixture.

[0063] After all the pins of the magnetic rings on the first fixture are corrected, they will move to the corresponding unloading device 8 position. The piston rod of the unloading slide cylinder 81 extends, driving the push plate 82 to move forward, pushing the fixture out and storing it in the receiving plate 83, thus completing the processing of a set of magnetic rings.

[0064] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
