Description

[0002] In mechanical manufacturing, automated assembly is replacing manual assembly to improve production efficiency. When assembling military and scientific equipment, special parts such as ball bearings and springs need to be transported to the assembly area. Existing assembly equipment cannot adjust the feeding position of the conveyor according to the specifications of the ball bearings, springs, or the equipment being assembled. Furthermore, when the assembly area is in a strong magnetic field, the ball bearings and springs become magnetic, reducing assembly accuracy and efficiency. When assembling ball bearings and springs, existing equipment cannot detect the pressure required to press them into the workpiece, nor can it determine whether the assembly is complete.

[0003] Therefore, existing assembly equipment suffers from poor assembly accuracy and efficiency, as well as insufficient flexibility and functionality in strong magnetic environments. Summary of the Invention

[0087] The following description, in conjunction with the accompanying drawings and embodiments of the invention, provides a more detailed account of a ball and spring assembly device for use in a strong magnetic environment.

[0088] like Figures 1-18 As shown, the ball and spring assembly device used in this strong magnetic environment includes: a loading platform 1 that carries the ball and spring assembly device, a feeding device 2 that conveys the ball and spring, a magnetic isolation device 3 that isolates the external magnetic field, and a pressing mechanism 4 with detection function that presses in the ball and spring.

[0089] In one embodiment, the feeding device 2 and the detection-equipped pressing mechanism 4 are fixedly connected to the loading platform 1, and the magnetic shielding device 3 is fixedly connected to the loading platform 1 via the support frame 5. The magnetic shielding device 3 is positioned above the discharge end of the feeding device 2, and the detection-equipped pressing mechanism 4 is positioned above the magnetic shielding device 3. When assembling balls and springs, the magnetic shielding device 3 is first controlled to reach the assembly position of the workpiece, then the feeding device 2 transports the balls and springs to the assembly position, and finally the detection-equipped pressing mechanism 4 performs a pressing action to complete the assembly of the balls and springs. This ball and spring assembly device used in a strong magnetic environment has a simple structure, a high degree of automation in ball and spring assembly, and is unaffected by the strong magnetic field environment during ball and spring assembly.

[0090] To facilitate material conveying in ball and spring assembly devices used in strong magnetic field environments, the feeding device 2 includes a feeding body 21, a conveying device 22, and a pushing device 23. The feeding body 21 is fixedly connected to the loading platform 1, and the conveying device 22 is fixedly connected to the feeding body 21. The pushing device 23 is slidably connected to the upper side of the feeding body 21 and is slidably connected inside the conveying device 22, allowing the pushing device 23 to push the balls and springs inside the conveying device 22 into the assembly area. By driving the pushing device 23 to slide towards the conveying device 22, the pushing device 23 moves the material inside the conveying device 22, thus achieving the feeding process. This feeding device has a simple, flexible, and convenient structure. By driving the pushing device 23 to extend into the conveying device 22, it pushes the balls and springs to the product assembly area, thereby automating the material conveying process. Simultaneously, the conveying position of the feeding device can be changed via the feeding body 21, meeting the need for timely adjustments to the conveying position due to differences in the assembly positions of different products and balls and springs.

[0091] To facilitate the manufacturing of the conveying device 22, the conveying device 22 includes a connecting part 221, a feeding part 222, and a discharging part 223. The connecting part 221 is fixedly connected to the feeding machine body 21, and the feeding part 222 and the discharging part 223 are integrally formed and connected to the end face of the connecting part 221. By integrally forming and connecting the connecting part 221, the feeding part 222, and the discharging part 223, the technical problem of high processing cost caused by the complex structure of the conveying device 22 in the prior art is solved.

[0092] Furthermore, the feeding section 222 and the discharging section 223 are cylindrical in shape, and the through holes inside the feeding section 222 and the discharging section 223 are coaxial. The discharging section 223 is integrally formed and connected to the end of the feeding section 222 away from the connecting section 221, which prevents the balls and springs from being pushed out of the conveying device 22 by the pushing device 23, and ensures the stability of the ball and spring conveying by the integral connection of the feeding section 222 and the discharging section 223.

[0093] Furthermore, the connecting part 221 includes: a transition platform 2211, a balancing platform 2212, and a connecting base 2213. One end of the transition platform 2211 is integrally formed and connected to the material placement part 222 and the material discharge part 223, while the other end of the transition platform 2211 is sequentially integrally formed and connected to the balancing platform 2212 and the connecting base 2213. The connecting base 2213 is fixedly connected to the feeder body 21, and the balancing platform 2212 is slidably connected to the pushing device 23. The transition platform 2211 bears the impact force of the pushing device 23, the connecting base 2213 bears the conveying device 22, and the balancing platform 2212 bears the pushing device 23. The transition platform 2211, the balancing platform 2212, and the connecting base 2213 can be rationally designed according to the weight of the conveying device 22 and the pushing device 23 and the speed of the conveyed material, thereby improving the stability of the feeding device structure. At the same time, the integral connection of the transition platform 2211, the balancing platform 2212, and the connecting base 2213 reduces the processing difficulty and cost of the conveying device 22. Finally, the balancing platform 2212 can serve as the track for the pushing device 23 to operate, ensuring the stability of the pushing device 23.

[0094] To allow the springs and balls to be placed into the placement section 222, a spring slot 6 and a ball hole 7 are provided on the upper side of the placement section 222, so that the spring slot 6 and the ball hole 7 are respectively connected to the through hole of the placement section 222. This allows the balls and springs to be directly inside the placement section 222, shortening the conveying distance of the balls and springs from the placement position to the assembly area, thereby improving the material conveying efficiency. To facilitate subsequent assembly of the balls and springs, the discharge section 223 is a groove-shaped channel with an open upper part that extends into the upper side of the through hole of the discharge section 223. This facilitates the conveying of the balls and springs to the assembly position. At the same time, the open upper part of the discharge section 223 facilitates subsequent equipment to press the balls and springs into the workpiece to complete the assembly of the springs and balls.

[0095] Furthermore, by making the distance from the top of the opening of the discharge section 223 to the bottom of the discharge section 223 2 / 3 of the outer diameter of the material placement section 222, the material usage can be reduced while the pressing operation of the ball and spring can be completed better.

[0096] In order to shorten the conveying distance of the balls and springs while conveying them to the assembly area, the length of the discharge section 223 is made twice the sum of the length of the spring groove 6 and the length of the ball hole 7. Shortening the conveying distance of the balls and springs improves their conveying efficiency and reduces material usage, thus achieving the technical effect of reducing processing costs.

[0097] To prevent the pushing device 23 from colliding with the connecting part 221 during the return trip, which could cause the feeding device to malfunction, the feeding device also includes a limiting plate 8, which is fixedly connected to the end of the connecting part 221 away from the material placement part 222 to limit the movement area of ​​the sliding table 231.

[0098] To improve the flexibility and adaptability of the feeding device, the feeding body 21 includes a horizontal moving device 211 and a base 212. Horizontal slide rails 9 are fixedly connected to both sides of the upper part of the base 212, and horizontal sliding grooves are formed on both sides of the bottom of the horizontal moving device 211, slidably connecting the horizontal moving device 211 and the base 212. This allows the horizontal moving device 211 to move along the horizontal slide rails 9 on both sides of the upper part of the base 212, thereby changing the feeding position of the feeding device and solving the technical problem of insufficient flexibility in the existing feeding device. Simultaneously, the two horizontal slide rails 9 effectively ensure the smooth operation of the horizontal moving device 211, preventing the conveying device 22 from colliding with the workpiece at the assembly position due to unstable operation of the horizontal moving device 211.

[0099] Furthermore, to automate the driving of the horizontal moving device 211, the feeder body 21 also includes a toothed transmission component 10, which is fixedly connected to the inner side of the horizontal moving device 211. The feeder body 21 also includes a first belt conveyor 213, with its motor and two pulleys fixed to opposite ends of the base 212. The belt of the first belt conveyor 213 is a toothed belt, engaging with the toothed transmission component 10. By controlling the direction of the toothed belt of the first belt conveyor 213, the toothed transmission component 10 engaged with the toothed belt moves, thereby driving the horizontal moving device 211 to move left and right horizontally, thus automating the reciprocating motion of the horizontal moving device 211.

[0100] A guide rail 11 is fixedly connected above the horizontal moving device 211. The horizontal moving device 211 and the pushing device 23 are slidably connected through the guide rail 11, allowing the pushing device 23 to move along the guide rail 11. At the same time, the pushing device 23 is also fitted onto the balance platform 2212, which improves the stability of the movement of the pushing device 23.

[0101] To allow the pushing device 23 to enter the channels of the material placement section 222 and the material discharge section 223, and to push the balls and springs from the material placement section 222 to the port of the material discharge section 223, the pushing device 23 includes a sliding table 231, a pushing rod 232, and an engaging part 233. A sliding groove is provided at the bottom of the sliding table 231, allowing the sliding table 231 to slide slidably connect to the feeder body 21. The sliding table 231 is fitted over the outside of the balance table 2212. The pushing rod 232 is fixedly connected to the end face of the sliding table 231 and extends into the through hole inside the material placement section 222. The engaging part 233 is fixedly connected to the side of the sliding table 231. The sliding table 231 can slide along the guide rail 11 and the connecting part 221, thereby driving the pushing rod 232 to move along the channel of the material placement section 222 towards the port of the material discharge section 223. During this movement, the balls and springs are pushed along the channel towards the assembly position, completing the conveying process of the balls and springs.

[0102] To automate the driving of the pushing device 23, the pushing device 23 further includes a second belt conveyor 234, with its motor and two pulleys connected to both ends of the side of the connecting part 221. The belt of the second belt conveyor 234 is a toothed belt, and the second belt conveyor is engaged with the meshing part 233 of the second belt conveyor 234. By controlling the movement of the toothed belt of the second belt conveyor 234, the meshing part 233 engaged with the toothed belt is driven to move, thereby achieving the technical effect of controlling the sliding process of the pushing device 23.

[0103] The magnetic shielding device 3 includes: a support plate 31 supporting the magnetic shielding device 3, a magnetic shielding component 32 that isolates external magnetic fields, a linear slide rail 33 that assists in the movement of the magnetic shielding device 3, and a feeding device 34 that drives the movement of the magnetic shielding device 3. The magnetic shielding device 3 has a simple structure and can flexibly change the position of the magnetic shielding area while isolating the magnetic field. This solves the technical problem in the prior art where, when the area to be assembled is in a strong magnetic field environment, the product to be processed becomes magnetic, thereby reducing the product assembly accuracy and efficiency.

[0104] The support plate 31 is fixedly connected to the loading platform 1 via the support frame 5. The feeding device 34 is fixedly connected to the lower side of the support plate 31, and the linear slide rail 33 is fixedly connected to the support plate 31. One side of the magnetic shielding component 32 is driven to connect with the feeding device 34, and the other side is slidably connected with the linear slide rail 33, allowing the magnetic shielding component 32 to slide under the drive of the feeding device 34. The feeding device 34 drives the magnetic shielding component 32 to move along the linear slide rail 33 on the support plate 31, bringing the magnetic shielding component 32 above the ball and spring assembly position, achieving the technical effect of isolating the magnetic field. At the same time, the magnetic shielding component 32 not only moves to the ball and spring assembly area via the feeding device 34, but also improves the stability of the movement of the magnetic shielding component 32 with the assistance of the linear slide rail 33.

[0105] To reduce the use of magnetic shielding material and lower product processing costs, the magnetic shielding component 32 includes a moving platform 321 and a magnetic shielding plate 322. The moving platform 321 is connected to the feeding device 34 and the linear guide rail 33, and the magnetic shielding plate 322 is fixedly connected to the end face of the moving platform 321 away from the feeding device 34. In one embodiment, the magnetic shielding plate 322 is welded to the end face of the moving platform 321. Without affecting the magnetic shielding effect of the magnetic shielding component 32, the technical effect of reducing the processing cost of the magnetic shielding component 32 is achieved by reducing the amount of magnetic shielding material used.

[0106] To improve the stability of the moving platform 321 during movement, a sliding groove is provided at the bottom of the moving platform 321. One side of the moving platform 321 is driven and connected to the feeding device 34, and the other side of the moving platform 321 is slidably connected to the linear guide rail 33 through the sliding groove. The feeding device 34 drives the moving platform 321 to and from the assembly area, and the sliding connection between the moving platform 321 and the linear guide rail 33 through the sliding groove assists the movement of the moving platform 321. When the moving platform 321 is automatically driven, the magnetic plate 322, which is fixedly connected to the moving platform 321, can accurately reach the assembly area of ​​the balls and springs, improving the assembly efficiency of the balls and springs.

[0107] Furthermore, the length of the magnetic shielding plate 322 is less than the length of the moving platform 321, and the magnetic shielding plate 322 is located at one end of the moving platform 321 connected to the linear slide rail 33. By rationally designing the length and position of the magnetic shielding plate 322, the magnetic shielding plate 322 can reach the assembly area of ​​the balls and springs, isolating external magnetic fields and further reducing the use of magnetic shielding materials.

[0108] In order to facilitate the magnetic shielding plate 322 to reach the assembly area of ​​the ball and spring, a product arc opening is provided at one end of the magnetic shielding plate 322 away from the moving platform 321. In order to adapt the magnetic shielding plate 322 to the product to be processed, the structure and size of the product arc opening are in the same length direction as the fixed axis of the product to be shielded.

[0109] To automate the feeding motion of the magnetic shielding device 3 used in this strong magnetic environment, the feeding device 34 is a lead screw feeding device. Further, the lead screw feeding device includes: a servo motor 341, a screw 342, a nut 343, and a nut sleeve 344. The servo motor 341 is fixedly connected to the support plate 31 via a connector 12. The servo motor 341 is fixedly connected to the screw 342 via a coupling 13. The nut 343 is threadedly driven to the screw 342. The nut sleeve 344 is fixedly connected to the nut 343 and to the magnetic shielding component 32. By controlling the forward and reverse rotation of the servo motor 341, the magnetic shielding component 32, fixedly connected to the nut sleeve 344, reciprocates along the direction of the screw 342. When assembling balls and springs, the lead screw feeding device drives the magnetic shielding component 32 to the magnetic shielding area, preventing the balls and springs from becoming magnetic and reducing the assembly effect. After the ball bearings and springs are assembled, the magnetic shielding component 32 is driven by the lead screw feed device to achieve the return stroke, thus realizing the technical effect of automatically driving the magnetic shielding component 32.

[0110] To prevent the magnetic shielding device 3 from colliding with or detaching from the linear guide rail 33 and screw 342 due to equipment failure or improper operation, the magnetic shielding device used in this strong magnetic environment also includes a first limiting member 14 and a second limiting member 15. The first limiting member 14 and the second limiting member 15 are located at opposite ends of the screw 342 and are fixedly connected to the support plate 31. Specifically, the first limiting member 14 is located at the end of the screw 342 furthest from the servo motor 341 and is fixedly connected to the support plate 31, while the second limiting member 15 is located at the end of the screw 342 closest to the servo motor 341 and is fixedly connected to the support plate 31. By limiting the movement trajectory of the magnetic shielding member 32 with the first limiting member 14 and the second limiting member 15, serious damage to the magnetic shielding member 32 due to improper operation by technicians or malfunction of the magnetic shielding device is avoided, thus preventing a reduction in the efficiency of the magnetic shielding device in isolating the magnetic field in this strong magnetic environment.

[0111] When the feeding device 34 is in automatic feeding motion, excessive operating speed causes the screw 342 to vibrate violently, causing the magnetic shielding component 32 to collide with other equipment and preventing it from reaching the magnetic shielding area, thus reducing the effectiveness of the magnetic shielding device 3 in isolating the magnetic field in this strong magnetic environment. Therefore, limiting holes 16 are respectively opened through the first limiting member 14 and the second limiting member 15, allowing the screw 342 to pass through the limiting holes 16. By limiting the amplitude of the screw 342's vibration through the limiting holes 16, the technical problem of the magnetic shielding component 32 vibrating violently due to excessive operating speed, causing it to collide with other equipment and preventing it from reaching the magnetic shielding area is solved. Of course, in order for the screw 342 to pass through the limiting holes 16, the size of the limiting holes 16 is larger than the diameter of the screw 342. To further limit the amplitude of the screw 342's wobbling, a support member 17 is provided at the end of the second limiting member 15 away from the servo motor 341. The screw 342 passes through the support member 17, which supports the screw 342. A protruding ring is provided at the end of the support member 17 near the second limiting member 15. The outer diameter of the protruding ring is the same as the inner diameter of the limiting hole 16, and the protruding ring is engaged inside the limiting hole 16.

[0112] Of course, in order not to affect the rotation of the screw 342, the support member 17 is provided with a support hole, the screw 342 is set through the support hole, and a load-bearing bearing is provided between the support hole and the screw 342.

[0113] The pressure-pressing mechanism 4 with detection includes: a frame 41 supporting the pressure-pressing mechanism, a pressure-pressing assembly 42, a lifting device 43, and a pressure detection device 44 for detecting the magnitude of the pressure. The pressure-pressing mechanism 4 with detection has a simple structure, is easy to operate, and has the function of detecting the magnitude of pressure.

[0114] In one embodiment, a lifting device 43 is connected to a frame 41, and a pressing assembly 42 is detachably connected to the lifting device 43. A pressure detection device 44 is located inside the pressing assembly 42 to detect and measure the downward pressure of the pressing assembly 42. The lifting device 43 controls the pressing assembly 42 to perform a pressing action, completing the assembly of the ball bearings and springs. At the same time, the pressure detection device 44 records the pressure required to assemble the ball bearings and springs, determining whether the assembly of the ball bearings and springs has been successfully completed.

[0115] To improve the pressing effect of the pressing mechanism 4 with detection, the pressing assembly 42 includes a pressing member 421 and a buffer member 422, with the buffer member 422 fitted onto the pressing member 421. This prevents damage to the workpiece during pressing and also extends the service life of the pressing assembly 42. To facilitate the fitting of the buffer member 422 onto the pressing member 421, the buffer member 422 is made of a material with a rebound effect, such as rubber or silicone, and the diameter of the sleeve portion of the buffer member 422 is slightly smaller than the diameter of the pressing member 421 to prevent the buffer member 422 from detaching from the pressing member 421.

[0116] Furthermore, the buffer component 422 includes: a connecting sleeve 4221, a bearing plate 4222, and a lower pressure sleeve 4223. The connecting sleeve 4221, the bearing plate 4222, and the lower pressure sleeve 4223 are integrally formed and connected sequentially, so that the inner wall of the connecting sleeve 4221 fits into the lower pressure component 421. The connecting sleeve 4221 and the lower pressure component 421 are fitted together with an interference fit, and the bottom of the connecting sleeve 4221 is sealed and fixed by the bearing plate 4222. By integrally forming the components of the buffer component 422—the connecting sleeve 4221, the bearing plate 4222, and the lower pressure sleeve 4223—the number of processing steps for the buffer component 422 is reduced, thus lowering its processing cost. Simultaneously, by using the bearing plate 4222 as a carrier to bear the downward pressure applied to the buffer component 422 by the lower pressure component 421, the downward pressure is ensured to be evenly distributed. This not only ensures stable pressing of the balls and springs but also helps to improve the service life of the buffer component 422.

[0117] To ensure that the pressing mechanism with detection can press the balls and springs into the product to be pressed, the lower end of the pressing sleeve 4223 is made into an open cylindrical structure, and the wall thickness of the pressing sleeve 4223 is the same as or greater than the wall thickness of the product to be pressed; and the inner diameter of the pressing sleeve 4223 is the same as the inner diameter of the product to be pressed.

[0118] To facilitate the detection of the downward pressure, the pressure detection device 44 is a plate-shaped structure. The pressure detection device 44 is mounted on the surface of the support plate 4222. When the pressing mechanism with detection is in operation, the pressing component 42 contacts the product to be pressed and begins to press in the balls and springs. During the pressing process, since the support plate 4222 is fixedly connected to the bottom of the connecting sleeve 4221, the pressure detection device 44, mounted on the surface of the support plate 4222, can detect the pressure applied by the pressing component 421 as it presses in the balls and springs. Simultaneously, the pressure detection device 44 does not directly contact the product to be pressed during pressure detection, avoiding interference with the assembly process of the product and the balls and springs.

[0119] To improve the sensitivity of the pressure detection device 44, a pressure-sensitive adhesive is used, which is fixedly connected to the bottom of the pressing component 421. When the pressing mechanism with detection performs a pressing action, the pressing component 421 applies pressure to the buffer component 422. With the pressure-sensitive adhesive placed at the bottom of the pressing component 421, the pressure applied by the pressing component 421 to the product to be pressed can be accurately detected when the pressing component 421 contacts and presses against the support plate 4222. This information is then fed back to the data processing device to determine whether the ball bearings and springs have been successfully pressed into the workpiece.

[0120] To enable the lowering and raising component 42 to perform pressing and raising actions, the lifting device 43 includes: a telescopic body 431, a sliding sleeve 432, and a support guide rail 433. The sliding sleeve 432 is slidably connected to the support guide rail 433, with one end of the sliding sleeve 432 driven to slide along the support guide rail 433. Extending the telescopic body 431 causes it to move downwards along the support guide rail 433, detachably connecting the sliding sleeve 432 to the lowering component 42, thus driving the lowering component 42 downwards and completing the pressing action. Retracting the telescopic body 431 causes it to move upwards along the support guide rail 433, detachably connecting the sliding sleeve 432 to the lowering component 42, thus driving the lowering component 42 upwards and completing the raising action.

[0121] To ensure the safe operation of the pressure-down mechanism with detection, the lifting device 43 also includes a photoelectric sensor 434. The photoelectric sensor 434 is fixedly connected to one side of the telescopic body 431 and is used to control the movement trajectory of the sliding sleeve 432.

[0122] To automate the telescopic movement of the telescopic component body 431, the telescopic component body 431 is an electrically telescopic rod. Further, the sliding sleeve 432 includes: an upper plate 4321, a lower plate 4322, a connecting inner plate 4323, and a connecting outer plate 4324. The upper plate 4321 and lower plate 4322 are respectively fixedly connected to the upper and lower ends of the connecting outer plate 4324. The pressing assembly 42 is detachably connected to the lower side of the lower plate 4322 for easy replacement or maintenance. To allow the sliding sleeve 432 to fit onto the support guide rail 433, a guide rail cavity 4325 is provided between the connecting outer plate 4324 and the connecting inner plate 4323. Connecting plates 4326 are used to fix the guide rail 4325 on both sides, allowing the support guide rail 433 to pass through the guide rail cavity 4325. The guide rail cavity 325 allows the sliding sleeve 432 to move along the support guide rail 433, ensuring the stability of the sliding sleeve 32's operation. This, in turn, ensures that the pressing assembly 42 accurately reaches the assembly area of ​​the product to be pressed, improving the pressing efficiency of the pressing mechanism with detection. A pressure detection device 44 and a data processing device are fixedly connected to the upper side of the upper plate 4321, which can visually detect the magnitude of the pressing force and determine whether the assembly has been successfully completed based on the pressing force of the ball bearings and springs.

[0123] Furthermore, to improve the stability of the sliding sleeve 432's movement, the supporting guide rail 433 is a plate-shaped mechanism, with the distance between the connecting inner plate 4323 and the connecting outer plate 4324 being the same as the thickness of the supporting guide rail 433. By reducing the clearance between the sliding sleeve 432 and the supporting guide rail 433, the amplitude of the sliding sleeve 432's swaying is reduced, ensuring that the pressing assembly 42 accurately reaches the assembly area of ​​the product to be pressed. To support the supporting guide rail 433, the frame 41 includes: a support body 411 and a guide rail support frame 412. The guide rail support frame 412 is fixedly connected to the upper side of the support body 411, and the guide rail 433 is fixedly connected to the guide rail 412. The guide rail support frame 412 includes: an upper baffle 4121, a lower baffle 4122, and a back plate 4123. The upper baffle 4121 and the lower baffle 4122 are fixedly connected to the upper and lower ends of the back plate 4123, respectively, and the back plate 4123 is fixedly connected to the bracket body 411. The support guide rail 433 is provided between the upper baffle 4121 and the lower baffle 4122. The telescopic component body 431 is connected between the upper baffle 4121 and the lower baffle 4122. The drive motor of the telescopic component body 431 is located at the upper end of the upper baffle 4121, and the drive shaft of the drive motor passes through the upper baffle 4121 and is drivenly connected to the telescopic component body 431.
