Description

Technical Field

[0001] This utility model demonstrates an assembly mechanism for riveting copper sleeves on circuit boards, belonging to the field of copper sleeve riveting technology. Background Technology

[0002] During the manufacturing process of a circuit board, two copper sleeves need to be riveted together. These two copper sleeves need to be coaxial and symmetrically positioned. However, in the existing technology, the two copper sleeves on the circuit board are installed sequentially, that is, after riveting one copper sleeve, the other copper sleeve is riveted together. When riveting the second copper sleeve, the two copper sleeves need to be aligned to ensure that they are coaxial and symmetrically positioned. This alignment process requires the use of other alignment tools, which increases the complexity of the copper sleeve process and reduces the assembly efficiency of the copper sleeves. Utility Model Content

[0003] The purpose of this invention is to solve the problem of low assembly efficiency of copper sleeves. To this end, an assembly mechanism for riveting copper sleeves on circuit boards is provided. The feeding mechanism consists of two copper sleeves that hold the bearing and are placed symmetrically, so that no additional calibration tools are needed for calibration, which helps to improve the assembly efficiency of copper sleeves.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An assembly mechanism for riveting copper sleeves onto a circuit board includes a translation mechanism, a feeding mechanism, a picking mechanism, and an assembly mechanism. The translation mechanism includes a positioning stage for positioning a substrate and a translation component for adjusting the horizontal position of the positioning stage. The substrate includes several circuit boards with through holes for the pins of the copper sleeves to pass through. The feeding mechanism includes a feeding platform for providing copper sleeves, on which two copper sleeves are placed, coaxially and symmetrically. The picking mechanism includes two relatively fixed picking claws that simultaneously grip the copper sleeves and insert the pins into the through holes. The assembly mechanism bends the pins to fix the copper sleeves to the circuit board.

[0006] The beneficial effects of using this utility model are:

[0007] The feeding mechanism described in this utility model includes a feeding platform that can simultaneously place two copper sleeves, and the two copper sleeves can be placed coaxially and symmetrically on the feeding platform. The picking mechanism includes two relatively fixed picking claws that simultaneously pick up the two copper sleeves. During the process of the picking claws picking up the copper sleeves and installing them into the circuit board, the two copper sleeves remain relatively fixed. While the picking claws are fixed, the pins of the copper sleeves are bent by the assembly mechanism to complete the riveting of the copper sleeves. Therefore, during the assembly process of the copper sleeves, the two copper sleeves will not undergo relative displacement and can always remain coaxial and symmetrically placed. Therefore, there is no need to calibrate the copper sleeves, which can save the calibration process of the copper sleeves and eliminate the need for additional calibration tools. This can significantly improve the assembly efficiency of the copper sleeves without affecting the assembly difficulty.

[0008] Preferably, the feeding mechanism further includes a feeding channel for conveying copper sleeves. The feeding channel has two slides for the copper sleeves to slide along. The end of the feeding channel extends to a feeding platform, which has two placement slots located at the ends of the two slides. A baffle is provided on the side of each placement slot away from the feeding channel. The two copper sleeves are placed in the placement slots, abutting against the baffle and maintaining coaxial placement. Using the aforementioned technical solution, the feeding channel has two slides, each holding a copper sleeve. The copper sleeves are mirror-image placed within the two slides. When the copper sleeves slide through the slides to the feeding platform, they abut against the baffle and maintain coaxial placement. Therefore, when the picking claw simultaneously picks up two copper sleeves from the feeding platform, the two copper sleeves remain coaxial and symmetrically placed. Thus, the feeding channel and feeding platform can automatically complete the alignment of the two copper sleeves, eliminating the need for manual operation and making the alignment of the copper sleeves simpler and more convenient.

[0009] Preferably, the positioning stage is provided with a positioning plate and a push plate. The push plate pushes the substrate to abut against the positioning plate. The push plate and the positioning plate position the substrate in a first direction. The positioning stage is provided with a limiting block, which abuts against the substrate in a second direction intersecting the first direction to position the substrate. Using the aforementioned technical solution, the push plate, positioning plate, and limiting block can provide positioning in two basic directions, with the first and second directions intersecting. This effectively improves the basic positioning stability of the positioning stage, prevents the substrate from shifting position during the assembly of the copper sleeve, and makes the installation of the copper sleeve more precise and reliable.

[0010] Preferably, the positioning platform is provided with several limiting blocks. In the second direction, there is a gap between two adjacent circuit boards. The corner edges of the circuit boards have a curved structure. The limiting blocks include a first limiting part and a second limiting part. The width of the second limiting part gradually increases as it approaches the positioning plate. The push plate pushes the substrate to insert the first limiting part into the gap, and the side of the second limiting part abuts against the corner edge of the circuit board. Using the aforementioned technical solution, as the push plate presses against the substrate, the second limiting part gradually extends into the gap between the adjacent limiting plates. At the same time, the squeezing force between the corner of the circuit board and the second limiting part continuously increases. During this process, the limiting force of the limiting blocks on the substrate in the second direction continuously increases, thereby improving the positioning stability of the limiting blocks on the substrate in the second direction and further reducing the possibility of the substrate shaking.

[0011] Preferably, the translation component includes a base, a first translation driver, a second translation driver, a mounting base, and a slider. The first translation driver is fixed to the base, and the mounting base is fixedly connected to the second translation driver. The first translation driver drives the mounting base to slide on the base, and the slider is fixedly connected to the positioning stage. The second translation driver drives the slider to slide on the mounting base, and the sliding direction of the slider is perpendicular to the sliding direction of the mounting base.

[0012] Preferably, both ends of the copper sleeve are provided with slots, and the picking claw includes two claw bodies that can move closer or further apart from each other. Each claw body has a protrusion on its opposite side. The two claw bodies move closer together so that the protrusions insert into the slots to grip the copper sleeve. Using the aforementioned technical solution, during the gripping process, the protrusions of the claw bodies insert into the slots of the copper sleeve, which helps improve the positioning stability of the picking claw on the copper sleeve, reduces the possibility of the copper sleeve shaking after being gripped, and ensures that the two copper sleeves can always remain coaxially positioned.

[0013] Preferably, the copper sleeve is provided with a positioning groove, and the claw body is provided with a positioning part that matches the positioning groove. The two claw bodies are brought close together so that the positioning block is embedded in the positioning groove to achieve the positioning of the copper sleeve and the claw body.

[0014] Preferably, the assembly mechanism is located below the positioning table, which has a notch for avoiding the assembly mechanism. The assembly mechanism includes a bending assembly, a pressing assembly, a fixed seat, and a lateral movement driver for driving the fixed seat to move laterally. Both the bending assembly and the pressing assembly are mounted on the fixed seat. The moving direction of the fixed seat is parallel to the arrangement direction of the two copper sleeves. The bending assembly acts on the pin to bend the pin, and the pressing assembly presses the pin to make the pin abut against the lower surface of the circuit board.

[0015] Preferably, the bending assembly includes a bending driver, a lifting driver, and two bending members. The bending driver drives the two bending members to move closer to each other, and the two bending members act on the two pins respectively to bend the two pins relative to each other. The output terminal of the lifting driver is connected to the bending driver, and the lifting driver drives the bending driver to move up and down.

[0016] Preferably, the pressing assembly includes a pressing driver and a pressing rod. The pressing driver drives the pressing rod to move up and down, and the pressing rod acts on the bent pin to make the pin abut against the lower surface of the circuit board.

[0029] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] like Figures 1 to 9As shown in the figure, this embodiment demonstrates an assembly mechanism 4 for riveting copper sleeves 52 onto a circuit board 51. The assembly mechanism 4 rivets two copper sleeves 52 onto the circuit board 51 and includes a translation mechanism 3, a feeding mechanism 1, a picking mechanism 2, and an assembly mechanism 4. The translation mechanism 3 includes a positioning stage 36 for positioning the substrate 5 and a translation component for adjusting the horizontal position of the positioning stage 36. The substrate 5 includes several circuit boards 51, and the circuit boards 51 are provided with through holes through which the leads 53 of the copper sleeves 52 pass. The feeding mechanism 1 includes a feeding platform 12 for providing copper sleeves 52. The feeding platform 12 holds two copper sleeves 52, which are coaxial and symmetrically placed. The picking mechanism 2 includes two relatively fixed picking claws 21. The two picking claws 21 simultaneously clamp the copper sleeves 52 and insert the leads 53 into the through holes. The assembly mechanism 4 bends the leads 53 to fix the copper sleeves 52 onto the circuit board 51.

[0033] In this embodiment, the feeding mechanism 1 includes a feeding platform 12, which can simultaneously place two copper sleeves 52. The two copper sleeves 52 can be placed coaxially and symmetrically on the feeding platform 12. The picking mechanism 2 includes two relatively fixed picking claws 21. The two picking claws 21 simultaneously pick up the two copper sleeves 52. During the process of the picking claws 21 picking up the copper sleeves 52 and installing the copper sleeves 52 into the circuit board 51, the two copper sleeves 52 always remain relatively fixed. Under the fixed position of the picking claws 21, the pins 53 of the copper sleeves 52 are bent by the assembly mechanism 4, thereby completing the riveting of the copper sleeves 52. Therefore, during the assembly process of the copper sleeves 52, the two copper sleeves 52 will not undergo relative displacement and can always remain coaxial and symmetrically placed. Therefore, there is no need to calibrate the copper sleeves 52, which can save the calibration process of the copper sleeves 52 and eliminate the need to use additional calibration tools. This can significantly improve the assembly efficiency of the copper sleeves 52 without affecting the assembly difficulty of the copper sleeves 52.

[0034] like Figure 2 and Figure 3As shown, the feeding mechanism 1 in this embodiment further includes a feeding channel for conveying the copper sleeve 52. The feeding channel has two slide rails 111 for the copper sleeve 52 to slide on. One end of the feeding channel 11 extends to the feeding platform 12. The copper sleeve 52 is placed into the slide rail 111 from the other end of the feeding channel 11 and slides along the slide rail 111 towards the feeding platform 12. The feeding platform 12 has two placement slots 122, located at the ends of the two slide rails 111 respectively. A baffle 121 is provided on the side of the placement slot 122 away from the feeding channel. The two copper sleeves 52 are positioned within the placement slot 122 and close to the baffle 121. The copper sleeves 52 are placed coaxially against each other and are supported by two slides 111 in the feeding channel. The copper sleeves 52 are placed mirror images of each other in the two slides 111. When the copper sleeves 52 slide through the slides 111 to the feeding platform 12, the copper sleeves 52 and the baffles 121 are supported and placed coaxially. Therefore, when the picking claw 21 picks up two copper sleeves 52 from the feeding platform 12 at the same time, the two copper sleeves 52 are placed coaxially and symmetrically. Thus, the feeding channel 11 and the feeding platform 12 can automatically complete the calibration of the two copper sleeves 52, eliminating the manual operation process and making the calibration of the copper sleeves 52 simpler and more convenient.

[0035] like Figure 4 As shown, in this embodiment, both ends of the copper sleeve 52 are provided with slots 521, and the copper sleeve 52 is also provided with positioning grooves 522. The picking claw 21 includes two claw bodies 22 that can move closer or further away from each other. Each of the two claw bodies 22 has a protrusion 23 on its opposite side. The claw body 22 is also provided with a positioning part 24 that matches the positioning groove 522. When the two claw bodies 22 move closer, the protrusion 23 is inserted into the slot 521, and the positioning block is embedded in the positioning groove 522 to achieve the positioning of the copper sleeve 52 and the claw body 22. During the process of picking up the copper sleeve 52, the protrusion 23 of the claw body 22 is inserted into the slot 521 of the copper sleeve 52, which helps to improve the positioning stability of the picking claw 21 on the copper sleeve 52, reduce the possibility of the copper sleeve 52 shaking after being picked up, and ensure that the two copper sleeves 52 can always be placed coaxially.

[0036] like Figure 5As shown, the translation component in this embodiment includes a base 31, a first translation driver 32, a second translation driver 34, a mounting base 33, and a slider 35. The first translation driver 32 is fixed to the base 31, which has a slide rail. The output end of the first translation driver 32 is fixedly connected to the mounting base 33, and the mounting base 33 is slidably connected to the slide rail on the base 31. The first translation driver 32 drives the mounting base 33 to slide along the slide rail on the base 31. The second translation driver 34 is fixed to the mounting base 33, which also has a slide rail. The output end of the second translation driver 34 is fixedly connected to the slider 35. The slider 35 is slidably connected to the slide rail on the mounting base 33. The second translation driver 34 drives the slider 35 to slide along the slide rail on the mounting base 33. The slider 35 is fixedly connected to the positioning stage 36. The slide rail on the base 31 is perpendicular to the slide rail on the mounting base 33. That is, the sliding direction of the mounting base 33 is perpendicular to the sliding direction of the slider 35. The positioning stage 36 can be controlled to move in the horizontal direction by the first translation driver 32 and the second translation driver 34, thereby adjusting the position of the substrate 5 on the platform.

[0037] like Figure 6 and Figure 7 As shown, in this embodiment, the positioning platform 36 is provided with a positioning plate 372 and a push plate 371 on both sides. The positioning platform 36 is provided with a first driver that drives the push rod to move closer to or away from the positioning plate 372. After the substrate 5 is placed on the positioning platform 36, the first driver controls the push plate 371 to move closer to the positioning plate 372. The push plate 371 pushes the substrate 5 to move towards the positioning plate 372 until both sides of the substrate 5 are clamped by the push plate 371 and the positioning plate 372, thereby achieving positioning of the substrate 5 in the first direction. The positioning platform 36 is provided with a limiting block 38. The limiting block 38 abuts against the substrate 5 in a second direction that intersects with the first direction to position the substrate 5. The push plate 371, the positioning plate 372, and the limiting block 38 can basically form positioning in two directions, and the first and second directions remain intersecting, which can effectively improve the basic positioning stability of the positioning platform 36, avoid the substrate 5 from shifting position during the assembly of the copper sleeve 52, and make the installation of the copper sleeve 52 more accurate and reliable.

[0038] In addition, the circuit boards 51 described in this embodiment are arranged in a matrix. In the second direction, there is a gap between two adjacent circuit boards 51. The corner edges of the circuit boards 51 are curved. The positioning platform 36 is provided with several limiting blocks 38. The limiting blocks 38 include a first limiting part 381 and a second limiting part 382. The width of the second limiting part 382 gradually increases as it approaches the positioning plate 372. During the process of the push plate 371 pushing the substrate 5 towards the positioning plate 372, the first limiting part 381 of the limiting block 38 will be inserted into the gap between the two circuit boards 51. As the push plate 371 pushes, the side of the second limiting part 382 abuts against the corner edge of the circuit board 51. The squeezing force between the corner of the circuit board 51 and the second limiting part 382 will continuously increase. During this process, the limiting force of the limiting block 38 on the substrate 5 in the second direction will continuously increase, thereby improving the positioning stability of the limiting block 38 on the substrate 5 in the second direction and further reducing the possibility of shaking.

[0039] like Figure 8 and Figure 9 As shown, in this embodiment, the assembly mechanism 4 is located below the positioning table 36. The positioning table 36 is provided with a notch for avoiding the assembly mechanism 4. The assembly mechanism 4 includes a bending component 43, a pressing component 44, a fixed seat 42, and a transverse driver 41 for driving the fixed seat 42 to move laterally. The bending component 43 and the pressing component 44 are both mounted on the fixed seat 42. The moving direction of the fixed seat 42 is parallel to the arrangement direction of the two copper sleeves 52. The bending component 43 acts on the pin 53 to bend the pin 53. The pressing component 44 presses the pin 53 to make the pin 53 abut against the lower surface of the circuit board 51.

[0040] Specifically, in this embodiment, the bending assembly 43 includes a bending driver 432, a lifting driver 431, and two bending members 433. The bending driver 432 drives the two bending members 433 to move closer to each other, and the two bending members 433 act on the two pins 53 respectively to bend the two pins 53 relative to each other. The output end of the lifting driver 431 is connected to the bending driver 432, and the lifting driver 431 drives the bending driver 432 to move up and down. The pressing assembly 44 includes a pressing driver 441 and a pressing rod 442. The pressing driver 441 drives the pressing rod 442 to move up and down, and the pressing rod 442 acts on the bent pins 53 to make the pins 53 abut against the lower surface of the circuit board 51.

[0041] The assembly process of the copper sleeve 52 in this embodiment is as follows: The user provides the copper sleeve 52 to the feeding mechanism 1 and places the substrate 5 on the positioning stage 36. The push plate 371 pushes the substrate 5 so that the push plate 371 and the positioning plate 372 clamp the substrate 5, thereby forming the positioning of the substrate 5. The copper sleeve 52 slides along the feeding channel 11 to the feeding platform 12. The feeding platform 12 is equipped with a detector to detect whether the two placement slots 122 have copper sleeves 52 at the same time, ensuring that the picking mechanism 2 can pick up two copper sleeves 52 at the same time. Then, the picking mechanism 2 controls the picking claw 21 to pick up two copper sleeves 52 at the same time and inserts the pins 53 of the copper sleeve 52 into the through holes on the circuit board 51. At this time, the picking claw 21 holds the copper sleeve 52. Then, the transverse drive 41 in the assembly mechanism 4 controls the fixed seat 42 to slide, so that the bending assembly 43 and the pressing assembly 44 are aligned with the pins 53. The lifting driver 431 controls the bending driver 432 and the bending component 433 to rise, so that the two pins 53 of the copper sleeve 52 are between the two bending components 433. The bending driver 432 controls the two bending components 433 to move closer to each other. The bending component 433 acts on the pins 53 to bend the pins 53. After that, the bending assembly 43 resets. The top pressure driver 441 controls the top rod 442 to rise. The top rod 442 acts on the bent pins 53 to make the pins 53 abut against the lower surface of the circuit board 51. Then, the horizontal movement driver 41 controls the fixing seat 42 to adjust its position so that the assembly mechanism 4 can complete the riveting of two copper sleeves 52 on a circuit board 51. After the assembly is completed, the picking claw 21 releases the copper sleeves 52 and re-clamps the two copper sleeves 52. During this process, the translation component controls the positioning table 36 to move horizontally so that the next circuit board 51 to be installed is on the upper side of the assembly mechanism 4.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
