Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically to a silver spot welding equipment for inserts. Background Technology

[0002] In the field of electrical component manufacturing, soldering of inserts and silver dots is a common process step.

[0003] In existing silver spot welding equipment, the positioning table of the silver spot fixture is often inconvenient to replace during use.

[0004] When welding inserts and silver dots of different specifications, frequent changes of the positioning table are not only cumbersome to operate, but also prone to inaccurate positioning, affecting welding quality and production efficiency.

[0005] Meanwhile, existing insert feeding assemblies and silver dot feeding assemblies have problems such as low feeding efficiency and poor stability in their structural design, making it difficult to meet the needs of large-scale, high-precision production.

[0006] Therefore, there is an urgent need for a silver spot welding device that can solve the above problems. Summary of the Invention

The top of each transmission groove is inclined away from the mounting groove.

[0010] The locking assembly also includes a notch located at the bottom of the support frame, a base plate fixedly installed at the bottom of the through slot and slidably installed in the notch, and a return spring provided between the top surface of the base plate and the top of the notch.

[0011] The locking assembly includes a rotating ring rotatably mounted on the bottom of the floating platform. The rotating ring has several locking arc grooves that slide and engage with the lower end of each locking assembly. Floating grooves are opened on both sides of one end of each locking arc groove. Each floating groove has a locking block installed in it via a pressure spring. Both sides of the locking assembly have slots for engaging with the corresponding locking blocks.

[0012] The locking assembly also includes a reset arc groove on the rotating ring. A stop block that is fixedly connected to the bottom surface of the floating platform is slidably installed in the reset arc groove. A thrust spring is provided between one side of the stop block and one end of the reset arc groove. A triangular groove is opened on the outer peripheral wall of the rotating ring. A trigger structure that cooperates with the triangular groove is provided at the bottom of the floating platform. When each block engages with the corresponding slot, the thrust spring is compressed and the trigger structure engages with the triangular groove.

[0013] The triggering structure includes a tilting frame, an elastic element, and a torsion spring, which are rotatably mounted on the bottom of the floating platform via a pivot in the middle. One end of the tilting frame is a limiting end and is used to engage with the triangular groove, while the other end is a triggering end that abuts against the inner end of the elastic element. The torsion spring is used to apply a force to the triggering end to move towards the rotating ring.

[0014] The elastic element includes an outer vertical plate and an inner vertical plate fixed to the bottom of the floating platform, a slide rod that slides through the outer vertical plate and the inner vertical plate, a baffle in the middle of the slide rod, and a small spring between the baffle and the inner vertical plate.

[0015] The insert feeding assembly includes an insert vibratory feeder, a first U-shaped frame, a first pushing cylinder, a transverse frame, a lifting frame, a lifting block, a lifting cylinder, and a telescopic mechanical claw. The first U-shaped frame is fixed to the discharge port of the vibratory feeder. The first pushing cylinder is fixed to the end of the first U-shaped frame away from the telescopic mechanical claw, and the piston rod extends into the first U-shaped frame. The lifting frame is slidably installed in the transverse frame by the transverse cylinder. The lifting block is slidably installed in the lifting frame by the lifting cylinder. The telescopic mechanical claw is fixed on the lifting block.

[0016] It also includes a feeding pipe installed in the machine tool, with the upper end of the feeding pipe located below the telescopic mechanical claw and the other end extending outside the machine tool.

[0017] The silver dot feeding assembly includes a silver dot vibratory plate. A fixed plate is fixedly installed at the bottom of the discharge port of the silver dot vibratory plate. A transfer frame is slidably installed on the fixed plate via a transfer cylinder. The transfer frame is provided with a silver dot transfer groove. A cross groove is opened in the positioning groove. A second U-shaped frame with its inner cavity aligned with the cross groove and close to one end of the transfer frame is fixedly installed on the top of the floating platform. A second pushing cylinder with its piston rod aligned with the inner cavity of the second U-shaped frame is fixedly installed on the fixed plate. A third pushing cylinder is fixedly installed on the other side of the top of the floating platform, with its piston rod extending into the cross groove at the end away from the discharge pipe.

[0018] The beneficial effects of this invention are as follows:

[0019] By combining the disassembly and locking components, the positioning platform can be quickly disassembled and precisely positioned. When the positioning platform needs to be replaced, simply operate the trigger mechanism to release the locking component from the engaging component, and the positioning platform can be easily removed. During installation, the positioning platform is placed into the mounting slot, and as the positioning platform descends, the engaging component is automatically triggered to engage with the slot and socket, and then it is fixed by the locking component. The operation is simple, the positioning is accurate, and it greatly improves the flexibility and efficiency of production.

[0020] The coordinated operation of components such as the insert vibratory feeder, the first pusher cylinder, the transverse frame, the lifting frame, the lifting cylinder, and the telescopic mechanical claw enables automatic feeding, precise gripping, and placement of inserts, reducing manual intervention and improving feeding efficiency and stability. The design of the unloading pipe facilitates the smooth unloading of inserts after welding, ensuring the continuity of the production process.

[0021] The structure, including the silver spot vibratory feeder, transfer cylinder, transfer frame, second pusher cylinder, and third pusher cylinder, can accurately and efficiently deliver silver spots to the designated position, providing a stable supply of silver spots for the welding process and ensuring the consistency and stability of welding quality.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0036] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0037] The silver spot welding equipment for inserts provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0038] Example 1:

[0039] This application provides a silver spot welding device for inserts, including a machine base 1, a welding assembly 2, a silver spot feeding assembly 3, an insert feeding assembly 4, and a silver spot fixture 5. The silver spot fixture 5 includes a frame 51, a floating table 52, a positioning table 53, and a disassembly and assembly assembly 6. The positioning table 53 can be detachably installed on the floating table 52 through the disassembly and assembly assembly 6. The disassembly and assembly assembly 6 includes a plurality of slots 61 symmetrically arranged on both sides of the positioning table 53, and each slot 61 has a slot 62. The floating table 52 is provided with an installation groove 63, and the side wall of the installation groove 63 is provided with a plurality of through grooves 64 corresponding to the slots 61. Each through groove 64 is provided with a floating mounting engagement assembly 7. The bottom of the floating table 52 is provided with a locking assembly 8. When the positioning table 53 descends to the bottom of the installation groove 63, each engagement assembly 7 engages with the corresponding slot 61 and slot 62. The locking assembly 8 is used to maintain or release the engagement state.

[0040] like Figures 1 to 11 As shown, due to the above structure, the positioning platform 53 is aligned with the mounting slot 63 of the floating platform 52, and the positioning platform 53 is slowly lowered. During the descent of the positioning platform 53, the slots 61 on both sides gradually contact the engaging components 7 in the through slot 64 of the floating platform 52. As the positioning platform 53 is pressed down, the engaging components 7 are squeezed and displaced, allowing the engaging components 7 to smoothly engage into the slots 61 and slots 62, achieving the initial connection between the positioning platform 53 and the floating platform 52. When the positioning platform 53 descends to the bottom of the mounting slot 63, the engaging components 7 are fully engaged with the slots 61 and slots 62. At this time, by operating the locking component 8, the engaging components 7 are locked, ensuring that the positioning platform 53 is stably installed on the floating platform 52, providing a stable positioning foundation for the subsequent welding of the insert and the silver point. If the positioning platform 53 needs to be replaced, the locking component 8 is operated in reverse to release the locking of the engaging components 7. Under the action of external pulling force, the positioning platform 53 can be removed from the mounting slot 63 of the floating platform 52.

[0041] Example 2:

[0042] In this embodiment, in addition to the structural features of the aforementioned embodiments, the engaging assembly 7 includes a support bracket 71 disposed on the outside of the through groove 64. The support bracket 71 has a support plate 72 on its outside and a sliding groove 73 on its top. A locking bracket 74 is disposed on the inside of the through groove 64. The top of the locking bracket 74 is bent and slidably inserted into the sliding groove 73. Slider blocks 75 are disposed on both sides. Several transmission grooves 79 are disposed on the inner wall of the opposite side of the through groove 64, which are respectively slidably engaged with each slider 75. The top of each transmission groove 79 is inclined away from the mounting groove 63.

[0043] In this embodiment of the application, the engaging assembly 7 further includes a notch 76 disposed at the lower part of the support bracket 71, a base plate 77 fixedly installed at the bottom of the through groove 64 and slidably installed in the notch 76, and a return spring 78 is provided between the top surface of the base plate 77 and the top of the notch 76.

[0044] like Figures 3 to 9 As shown, due to the above structure, when the positioning platform 53 descends, the slots 61 on both sides of the positioning platform 53 are inserted into the corresponding support brackets 71, and the bottom surface abuts against the top surface of each support plate 72. The positioning platform 53 continues to descend, pushing the support brackets 71 and the locking frame 74 to descend together. The slider 75 on the locking frame 74 slides from the upper end to the lower end of the transmission groove 79. Since the top of the transmission groove 79 is inclined away from the mounting groove 63, the locking frame 74 moves towards the center of the mounting groove 63 while sliding downward, and its upper end is precisely inserted into the slot 62. When the bottom surface of the positioning platform 53 contacts the bottom of the mounting groove 63, the locking component 8 fixes the lower ends of each support bracket 71 and the locking frame 74. During this process, the base plate 77 slides in the notch 76, and the return spring 78 is compressed and stores energy.

[0045] When the positioning platform 53 needs to be disassembled, the locking component 8 is released from the lower end of the support frame 71 and the locking frame 74. Under the elastic force of the return spring 78, the support frame 71 and the locking frame 74 are pushed to reset. The locking frame 74 slides upward and moves away from the mounting groove 63. The upper end disengages from the corresponding slot 62, so that the positioning platform 53 can be easily disassembled.

[0046] Compared with the prior art, the modular positioning table 53 design of this application reduces the replacement time from 30 minutes of traditional bolted connection to less than 1 minute, increases production capacity by more than 30%, and eliminates the need to replace the entire positioning tooling, only the positioning table 53 module needs to be replaced, reducing maintenance costs by more than 60%.

[0047] Example 3:

[0048] In this embodiment, in addition to the structural features of the aforementioned embodiments, the locking component 8 includes a rotating ring 81 rotatably mounted on the bottom of the floating platform 52. The rotating ring 81 is provided with a plurality of locking arc grooves 82 that are slidably engaged with the lower end of each engaging component 7. Floating grooves 83 are opened on both sides of one end of each locking arc groove 82. Each floating groove 83 is equipped with a locking block 85 by means of a pressure spring 84. Both sides of the engaging component 7 are provided with locking slots 86 for engaging with the corresponding locking block 85.

[0049] In this embodiment of the application, the locking component 8 further includes a reset arc groove 87 disposed on the rotating ring 81. A stop block 88 fixedly connected to the bottom surface of the floating platform 52 is slidably installed in the reset arc groove 87. A thrust spring 810 is provided between one side of the stop block 88 and one end of the reset arc groove 87. A triangular groove 89 is opened on the outer peripheral wall of the rotating ring 81. A trigger structure 9 that cooperates with the triangular groove 89 is provided at the bottom of the floating platform 52. When each locking block 85 is engaged with the corresponding locking slot 86, the thrust spring 810 is compressed and shortened, and the trigger structure 9 engages with the triangular groove 89.

[0050] In this embodiment of the application, the trigger structure 9 includes a flipping frame 91, an elastic element 92, and a torsion spring 93, which are rotatably mounted on the bottom of the floating platform 52 via a pivot in the middle. One end of the flipping frame 91 is a limiting end and is used to engage with the triangular groove 89, and the other end is a trigger end, which abuts against the inner end of the elastic element 92. The torsion spring 93 is used to apply a force to the trigger end to move towards the rotating ring 81.

[0051] In this embodiment of the application, the elastic member 92 includes an outer plate 921 and an inner plate 922 fixedly disposed at the bottom of the floating platform 52, a slide rod 923 slidably passing through the outer plate 921 and the inner plate 922, a baffle 924 provided in the middle of the slide rod 923, and a small spring 925 provided between the baffle 924 and the inner plate 922.

[0052] like Figures 7 to 9 As shown, due to the above structure, during the installation of the positioning platform 53, the triangular groove 89 is fully engaged with the limiting end of the flipping frame 91, the thrust spring 810 is compressed, and the entire locking assembly 8 is in a stable locked state. The lower ends of the support frame 71 and the locking frame 74 slide downward in the corresponding locking arc groove 82. When each slot 86 on the side wall of the support frame 71 and the locking frame 74 moves to the predetermined position, the locking block 85 pops out under the action of the pressure spring 84 and engages in the corresponding slot 86, completing the initial locking of the engagement assembly 7. When the positioning platform 53 needs to be disassembled, push the outer end of the slide rod 923 to move it toward the rotating ring 81. The small spring 925 is compressed and shortened. The inner end of the slide rod 923 pushes the trigger end of the flipping frame 91 toward the rotating ring 81, overcoming the force of the torsion spring 93. This causes the limiting end of the flipping frame 91 to disengage from the triangular groove 89. Under the action of the thrust spring 810, the rotating ring 81 rotates in the opposite direction. Each locking block 85 disengages from its corresponding locking slot 86, releasing the lock on the locking assembly 7. The positioning platform 53, each support frame 71, and the locking frame 74 rise, thereby realizing the disassembly of the positioning platform 53. Then, release the external force applied to the outer end of the slide rod 923. The small spring 925 releases its elastic potential energy to push the baffle 924 and the slide rod 923 away from the rotating ring 81. The torsion spring 93 releases its elastic potential energy to push the limiting end of the flipping frame 91 against the outer peripheral wall of the rotating ring 81. Then, rotate the rotating ring 81 to move each locking block 85 to below the corresponding locking assembly 7, completing the reset.

[0053] Example 4:

[0054] In this embodiment, in addition to the structural features of the aforementioned embodiments, the insert feeding assembly 4 includes an insert vibratory plate 41, a first U-shaped frame 42, a first pushing cylinder 43, a transverse frame 44, a lifting frame 45, a lifting block 46, a lifting cylinder 47, and a telescopic mechanical claw 48. The first U-shaped frame 42 is fixedly connected to the outlet of the insert vibratory plate 41. The first pushing cylinder 43 is fixedly disposed at the end of the first U-shaped frame 42 away from the telescopic mechanical claw 48, and the piston rod extends into the first U-shaped frame 42. The lifting frame 45 is slidably mounted in the transverse frame 44 by the transverse cylinder 49. The lifting block 46 is slidably mounted in the lifting frame 45 by the lifting cylinder 47. The telescopic mechanical claw 48 is fixedly disposed on the lifting block 46.

[0055] In this embodiment of the application, a feeding pipe 10 is also provided in the machine base 1. The upper end of the feeding pipe 10 is located below the telescopic mechanical claw 48, and the other end extends out of the machine base 1.

[0056] In this embodiment of the application, the silver dot feeding assembly 3 includes a silver dot vibratory plate 31. A fixed plate 32 is fixedly installed at the bottom of the discharge port of the silver dot vibratory plate 31. A transfer frame 34 is slidably installed on the fixed plate 32 via a transfer cylinder 33. The transfer frame 34 is provided with a silver dot transfer groove 39. A cross groove 35 is opened on the positioning table 53. A second U-shaped frame 36 with its inner cavity aligned with the cross groove 35 and close to one end of the transfer frame 34 is fixedly installed on the top of the floating table 52. A second pushing cylinder 37 with its piston rod aligned with the inner cavity of the second U-shaped frame 36 is fixedly installed on the fixed plate 32. A third pushing cylinder 38 is fixedly installed on the other side of the top of the floating table 52, and its piston rod extends into the cross groove 35 away from the end of the discharge pipe 10.

[0057] like Figures 10 to 11As shown, due to the aforementioned structure, the insert vibratory feeder 41 arranges the inserts in an orderly manner and conveys them to the first U-shaped frame 42. The piston rod of the first pushing cylinder 43 extends, pushing the inserts to the designated position. The lifting cylinder 47 drives the lifting block 46 to descend, causing the telescopic mechanical claw 48 to grasp the inserts. Subsequently, the lifting cylinder 47 rises, and the lateral movement cylinder 49 drives the lifting frame 45 to move laterally, transporting the inserts to the positioning platform 53 above the silver dot fixture 5. The lifting cylinder 47 descends again, accurately placing the inserts in the cross groove 35 near the end of the feed pipe 10. The silver dot vibratory feeder 31 arranges and conveys the silver dots to the silver dot transfer groove 39. The transfer cylinder 33 drives the transfer frame 34, causing the silver dot transfer groove 39 to receive the silver dots. 9. Move to between the second U-shaped frame 36 and the second pusher cylinder 37. The second pusher cylinder 37 operates, and its piston rod extends, causing the silver dots in the silver dot transfer groove 39 to slide through the inner cavity of the second U-shaped frame 36 to the center position of the cross groove 35. Then, the third pusher cylinder 38 pushes the silver dots onto the insert in the cross groove 35. The welding assembly 2 welds the silver dots onto the insert. After welding, a silver dot insert is obtained. The piston rod of the third pusher cylinder 38 continues to extend, pushing the silver dot insert away from the cross groove 35. The silver dot insert is discharged from the machine 1 through the discharge pipe 10. The piston rod of the third pusher cylinder 38 retracts to the end of the cross groove 35 away from the discharge pipe 10, completing the entire insert silver dot welding and loading / unloading process.
