Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic component manufacturing technology, specifically to a nut assembly machine. Background Technology
[0002] In the field of electronic component manufacturing, the plastic bases of transformers and inductors usually require embedded nuts to enable subsequent component connections and fixation.
[0003] Currently, this process largely relies on manual operation. However, manual nut installation is extremely inefficient. Due to the small size and large quantity of nuts, workers need to accurately place each nut into its corresponding slot on the plastic base, and then press it into place. This process is not only time-consuming but also prone to errors due to fatigue. Furthermore, manual operation is extremely labor-intensive; the repetitive and precise nut-insertion action over a long period puts significant strain on the workers' hands and eyes, easily leading to occupational fatigue and health problems. In addition, the quality of manual nut installation is difficult to guarantee. Due to human error, the nut insertion position may be inaccurate, resulting in insecure installation of subsequent components, or even nut loosening or falling off, thus affecting the performance and reliability of transformers and inductors.
[0004] Therefore, developing a nut assembly machine that can automatically install nuts is of great significance for improving production efficiency, reducing labor intensity, and enhancing product quality. Utility Model Content

[0022] This embodiment provides a nut assembly machine, as shown in the following example. Figures 1-9 The system includes a workbench 10, a product conveying mechanism 20, a positioning mechanism 30, a nut supply mechanism 40, a nut clamping and pressing mechanism 50, and a control mechanism 60. The product conveying mechanism 20 includes a conveyor frame 21 fixed on the workbench 10, a conveyor belt 22 rotatably mounted on the conveyor frame 21, and multiple carriers 23 mounted on the conveyor belt 22. The carriers 23 are used to carry products 200, and the products 200 have nut mounting grooves 201 for mounting nuts 400.
[0023] The positioning mechanism 30 is located on one side of the product conveying mechanism 20 and is used to position the carrier 23 so that when the nut clamping and pressing mechanism 50 installs the nut 400, the product 200 is not easily displaced, thus ensuring the installation quality.
[0024] The nut supply mechanism 40 is located on the side of the product conveying mechanism 20 away from the positioning mechanism 30, and is used to continuously supply nuts 400, with the end of it closest to the product conveying mechanism 20 being the nut supply end 401.
[0025] The nut clamping and pressing mechanism 50 is used to clamp the nut 400 on the nut supply end 401 to the carrier 23 at the positioning mechanism 30, and press the clamped nut 400 into the nut mounting groove 201 on the product 200 to achieve automatic installation of the nut 400.
[0026] The control mechanism 60 is electrically connected to the product conveying mechanism 20, the positioning mechanism 30, the nut supply mechanism 40, and the nut clamping and pressing mechanism 50, and is used to control the coordinated operation of the above mechanisms to achieve automatic installation of the nut 400.
[0027] During operation, product 200 is placed on carrier 23 and moves to positioning mechanism 30 as conveyor belt 22 rotates. Positioning mechanism 30 quickly and accurately positions carrier 23, ensuring product 200 remains stable during subsequent nut 400 installation. Simultaneously, nut supply mechanism 40 continuously supplies nuts 400 to nut supply end 401, providing a sufficient supply of nuts 400 for nut clamping and pressing mechanism 50. Nut clamping and pressing mechanism 50 clamps nuts 400 from nut supply end 401, delivers them above the positioned carrier 23, and then precisely places them into nut mounting slots 201 on product 200, applying appropriate pressure to firmly press the nuts 400 into the slots. This achieves automatic nut 400 installation without manual intervention, significantly improving production efficiency, reducing labor costs and labor intensity, while avoiding errors that may occur with manual operation, ensuring the installation quality of nuts 400, and improving the reliability and stability of product 200.
[0028] Furthermore, the nut supply mechanism 40 includes a vibratory feeder 41, a feeding track 42, and a lifting assembly. The vibratory feeding track 42 is connected to the outlet of the vibratory feeder 41. The vibratory feeder 41 is fixedly installed on one side of the workbench 10. The end of the feeding track 42 away from the vibratory feeder 41 is the nut supply end 401. The lifting assembly is located below the nut supply end 401 of the feeding track 42 and is used to lift the nuts 400 that are transported to the nut supply end 401 via the feeding track 42.
[0029] When the vibratory feeder 41 is started, the nut 400 slides smoothly along the feeding track 42 under the action of vibration until it reaches the nut supply end 401. At this time, the ejector assembly operates in a timely manner to lift the nut 400 located at the nut supply end 401 to a predetermined height, thereby facilitating the nut clamping and pressing mechanism 50 to perform clamping operations.
[0030] Furthermore, the nut supply mechanism 40 also includes a support frame 43 mounted on the workbench 10 for supporting the feeding track 42. The support frame 43 is located at the end of the feeding track 42 away from the vibratory plate 41. The top material assembly includes a top rod 44 movably mounted on the support frame 43 and a top material cylinder 45 for driving the top rod 44 to rise and fall. A first vertical groove 431 is provided on the top surface of the support frame 43. A second vertical groove 421 is provided on the feeding track 42 corresponding to the position of the first vertical groove 431. The top end of the top rod 44 passes upward through the first vertical groove 431 and the second vertical groove 421 and enters the feeding track 42. The top material cylinder 45 is fixedly mounted on the support frame 43. A device for driving the top rod 44 to rise and fall is fixedly connected to the power rod of the top material cylinder 45 to lift the nut 400 located on the nut supply end 401.
[0031] When the top-loading cylinder 45 is activated, the drive rod 44 rises along the first vertical groove 431 and the second vertical groove 421 until the top of the rod 44 lifts the nut 400 located at the nut supply end 401 to a predetermined height. This allows the nut clamping and pressing mechanism 50 to easily clamp the nut 400 to complete the subsequent feeding and pressing work, further improving the working efficiency and assembly quality of the nut assembly machine.
[0032] Furthermore, a top plate 46 is fixedly provided on the power rod of the top material cylinder 45, and an abutment groove 461 is provided on the top plate to abut against the top rod 44.
[0033] When the power rod of the top cylinder 45 extends and drives the top plate 46 to move closer to the top rod 44, the abutment groove 461 fits tightly with the top rod 44, thus ensuring that the top rod 44 remains stable during lifting and lowering without swaying or shifting. This enhances the smoothness of the lifting and lowering of the top rod 44 and further improves the accuracy of lifting the nut 400, ensuring that the nut 400 can be smoothly and accurately lifted to the predetermined height, facilitating subsequent clamping and pressing operations by the nut clamping and pressing mechanism.
[0034] Furthermore, a guide sleeve 432 is fixedly installed inside the first vertical groove 431. After the top end of the push rod 44 passes through the guide sleeve 432, it enters the feeding track through the second vertical groove 421. The inner wall of the guide sleeve 432 is provided with a plurality of balls 433 for rolling contact with the push rod 44.
[0035] The guide sleeve 432 provides precise guidance for the push rod 44, ensuring its linear movement during lifting and lowering, and reducing errors caused by offset or wobbling. Meanwhile, the introduction of the ball bearings 433 significantly reduces the frictional resistance between the push rod 44 and the inner wall of the guide sleeve 432, making the lifting and lowering action of the push rod 44 smoother and faster, reducing wear, and extending the service life of the equipment.
[0036] Furthermore, a top block 441 is provided on the outer sleeve of the top rod 44, the top end of the top rod 44 protrudes from the top block 441, the top block 441 is in clearance fit with the second vertical groove 421, and the diameter of the top end of the top rod 44 is smaller than the inner ring diameter of the nut 400.
[0037] When the push rod 44 rises and lifts the nut 400, the top block 441 ensures that the nut 400 is stably lifted without slipping. Since the diameter of the top end of the push rod 44 is smaller than the inner diameter of the nut 400, the nut 400 can be easily fitted onto the push rod 44. Simultaneously, the presence of the top block 441 prevents the nut 400 from shifting or falling during the lifting process, improving the working stability of the nut assembly machine and further ensuring the accuracy and reliability of the nut 400 during assembly.
[0038] Furthermore, the nut clamping and pressing mechanism 50 includes a mounting frame 51 fixedly mounted on the worktable 10, a movable seat 52 slidably mounted on the mounting frame 51 and movable along the X-axis, a lifting seat 53 slidably mounted on the movable seat 52 and movable along the Z-axis, a fixed seat 54 fixedly mounted on the lifting seat 53, a double-slider rodless cylinder 55 fixedly mounted on the bottom side of the fixed seat 54, and two grippers 56 respectively mounted on the two sliders of the double-slider rodless cylinder 55. The double-slider rodless cylinder 55 is used to drive the two grippers 56 to move towards each other or away from each other, so that the two grippers 56 can clamp or release the nut 400.
[0039] When the double-slider rodless cylinder 55 operates, its two sliders move synchronously, causing the two grippers 56 to move closer to or further away from each other. When the two grippers 56 move closer together, they clamp the nut 400, thus picking it up; when the two grippers 56 move further apart, they release the nut 400, thus placing it in place. This allows the nut clamping and pressing mechanism 50 to accurately clamp and place the nut 400, further improving the working accuracy and stability of the nut assembly machine.
[0040] In this embodiment, the X-axis direction is the length direction of the mounting frame 51. The mounting frame 51 is provided with an X-axis drive module 57 for driving the movable seat 52 to move along the X-axis direction. Through the setting of the X-axis drive module 57, the movable seat 52 can move back and forth between the product conveying mechanism 20 and the nut supply mechanism 40. The Z-axis direction is the height direction of the mounting frame 51. The movable seat 52 is provided with a Z-axis drive module 58 for driving the lifting seat 53 to move vertically up and down along the Z-axis direction, so that the lifting seat 53 can move accurately to the specified height. In conjunction with the X-axis drive module 57, the precise positioning of the nut 400 in three-dimensional space is realized, further improving the automation level and assembly efficiency of the nut assembly machine.
[0041] Furthermore, the nut clamping and pressing mechanism 50 also includes a pressing rod 59, which is located between two jaws 56 with its bottom end facing the nut 400 held by the two jaws 56. The pressing rod 59 is used to press the nut 400 into the nut mounting groove 201 after the two jaws 56 release the nut 400.
[0042] The pressure bar 59 ensures that the nut 400 is stably pressed into the nut mounting slot 201 after the gripper 56 is released, further improving the accuracy and reliability of the nut 400 installation. Furthermore, the coordinated action of the pressure bar 59 and the gripper 56 makes the entire nut 400 clamping and pressing process smoother and more efficient, meeting the dual requirements of high precision and high efficiency for the nut assembly machine.
[0043] In some specific embodiments, a connecting seat 531 is fixedly installed on the lifting seat 53. Side plates 532 are fixedly installed on the side of the connecting seat 531 opposite to the lifting seat 53. Sliding guide mechanisms 533 are provided on both sides of the fixed seat 54 and between the two side plates 532. That is, the fixed seat 54 is slidably connected to the two side plates 532 through the sliding guide mechanisms 533. The sliding guide mechanism 533 includes a slide rail 5331, a slider 5332, a limiting block 5333, and a guide rod 5334. The slide rail 5331 is fixedly installed on the opposite side of the side plates 532. The slider 5332 is slidably connected to the slide rail 5331, and the fixed seat 54 is fixedly connected to the bottom of the slider 5332. The limiting block 5333 is located at the top of the slide rail 5331. One end of the guide rod 5334 is located at the top of the limiting block 5333, and the bottom end of the guide rod 5334 passes downward through the limiting block 5333 and is fixedly connected to the top of the slider 5332.
[0044] A rib 534 is provided between the two side plates 532. A first fixing block 71535 is elastically connected to the bottom side of the rib 534. A second fixing block 71536 is provided on the side of the fixing seat 54 away from the first fixing block 71535. The top of the push rod 44 is fixedly connected to the first fixing block 71535. The bottom end of the push rod 44 passes downward through the fixing seat 54 and the second fixing block 71536 and extends into the space between the two clamps 56. The bottom end of the push rod 44 is located directly above the nut 400 held by the two clamps 56.
[0045] With the above settings, when pressing the nut 400, the Z-axis drive module 58 drives the lifting seat 53 to descend along the Z-axis direction, so that the two grippers 56 contact the top surface of the product 200, and the nut 400 between the two grippers 56 is precisely above the nut mounting groove 201. At this time, the double slider rodless cylinder 55 is driven to move, so that the two grippers 56 move away from each other, releasing the nut 400. At this time, the nut 400 automatically falls into the nut mounting groove 201. Then, the Z-axis drive module 58 continues to drive the lifting seat 53 to descend along the Z-axis direction, driving the connecting seat 531 to continue to descend. At this time, the fixed seat 54 cannot descend because the grippers 56 at its bottom are already in contact with the product 200, so the rib plate 534 descends relative to the fixed seat 54, thereby driving the top rod 44 to descend relative to the fixed seat 54, so that the top rod 44 can press the nut 400 into the nut mounting groove 201. That is, at this time, the nut 400 is installed in place, avoiding the nut 400 from loosening or falling off after installation.
[0046] Furthermore, it should be noted that in this embodiment, there are four nut mounting slots 201 on the product 200. Correspondingly, there are also four sets of feeding rails 42, top-loading components, grippers 56, and top rods 44. Each set of feeding rails 42, top-loading components, grippers 56, and top rods 44 corresponds to one nut mounting slot 201, enabling the simultaneous installation of four nuts 400, which further improves the assembly efficiency and production capacity of the nut assembly machine.
[0047] Furthermore, the positioning mechanism 30 includes a mounting base 31 fixedly disposed on one side of the conveyor frame 21, a positioning groove 32 opened on the conveyor frame 21, a positioning block 33 movably disposed in the positioning groove 32, and a positioning cylinder 34 for driving the positioning block 33 to move relative to the positioning groove 32 toward or away from the carrier 23. The conveyor frame 21 is provided with a rotating groove 11 adapted to the conveyor belt 22. The positioning groove 32 is disposed opposite to the mounting base 31. The positioning cylinder 34 is fixedly disposed on the mounting base 31. The power rod of the positioning cylinder 34 is fixedly connected to the positioning block 33.
[0048] When the carrier 23 moves to the designated position with the conveyor belt 22, the positioning cylinder 34 is activated. Its power rod pushes the positioning block 33 to move along the positioning groove 32 toward the carrier 23 until the positioning block 33 abuts against one side of the carrier 23, thereby accurately positioning the carrier 23. This ensures the stability of the product 200 when installing the nut 400 and improves the accuracy and efficiency of the nut 400 assembly.
[0049] Working Principle: During operation, the product 200 to be assembled is first placed on the carrier 23, which moves forward gradually with the conveyor belt 22. When the carrier 23 moves to the positioning mechanism 30, the positioning cylinder 34 is activated, pushing the positioning block 33 to quickly and accurately abut against one side of the carrier 23, ensuring the stability of the carrier 23 and the product 200 on it during the subsequent installation of the nut 400. At the same time, the vibratory feeder 41 in the nut supply mechanism 40 continuously vibrates, orderly conveying the nuts 400 along the feeding track 42 to the nut supply end 401. Subsequently, the top cylinder 45 in the top assembly is activated, pushing the top rod 44 upward, lifting the nut 400 located at the nut supply end 401 to a predetermined height, so that the nut clamping and pressing mechanism 50 can clamp it.
[0050] The nut clamping and pressing mechanism 50 starts working. The X-axis drive module 57 drives the moving seat 52 to move along the X-axis to above the nut supply end 401. Then, the Z-axis drive module 58 drives the lifting seat 53 to descend, allowing the two grippers 56 to accurately clamp the lifted nut 400. After clamping the nut 400, the Z-axis drive module 58 drives the lifting seat 53 to rise again, while the X-axis drive module 57 drives the moving seat 52 to move above the positioned carrier 23. At this time, the Z-axis drive module 58 drives the lifting seat 53 to descend again, so that the two grippers 56 contact the top surface of the product 200 and align the nut 400 held by the two grippers 56 with the nut mounting groove 201 on the product 200. By driving the double slider rodless cylinder 55, the two grippers 56 move away from each other, releasing the nut 400, which automatically falls into the nut mounting groove 201. Subsequently, the Z-axis drive module 58 drives the lifting seat 53 to descend again, which in turn drives the pressure rod 59 to descend, stably pressing the nut 400 into the nut mounting groove 201, thus completing the automatic installation of the nut 400.
[0051] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
