Description

Technical Field

[0001] This invention relates to the field of power strip manufacturing technology, and in particular to a spot welding fixture for conductive spring contacts in power strips. Background Technology

[0002] In the automated production of power strips, the assembly and welding of conductive springs and housings is one of the core processes. Currently, a dual-station linear slide module alternating operation is commonly used for spot welding. Two sets of slide modules operate alternately for continuous production. Specifically, after the slide module carries the power strip to the welding position, a fixture clamps and secures the power strip's housing and springs, followed by welding. After welding, the slide module then moves the power strip to the unloading position, where an unloading mechanism ejects the power strip. This dual-station alternating operation effectively reduces equipment downtime and improves production efficiency to some extent. However, current dual-station spot welding fixtures still have certain shortcomings: When the slide module carries the plug-in to move from the loading / unloading position to the welding position, a certain safety margin time needs to be reserved. Only after the slide module has completely stopped and confirmed to be in place can the control system trigger the fixture to perform the clamping action. Similarly, after welding is completed, the slide module moves the plug-in to the unloading position and stops completely before the unloading mechanism can perform the lifting action to push the plug-in out of the unloading position. In the intermittent work cycle of movement, stopping in place, performing the action, and moving again, the slide module needs to wait for a short pause at the welding position and the unloading position before performing the action. Although the pause time and the action time are short each time, in the large-scale, continuous production of plug-in, the pause time and the action time after the pause accumulate, resulting in a certain efficiency loss, which in turn leads to the need to improve the plug-in production capacity. Summary of the Invention

A clamping assembly and a driving assembly, wherein the driving assembly is used to drive the clamping assembly to clamp the conductive spring sheet within the housing as the linear slide module moves toward the welding position; A clamping assembly, which is used to simultaneously clamp the outer shell when the clamping assembly clamps the conductive spring sheet; The unloading module includes a roller assembly and a drive frame. The drive frame is used to drive the roller assembly to lift and unload the welded plug bar during the process of the linear slide module moving downward to the material position.

[0006] As a preferred embodiment of the conductive spring contact welding fixture for the power strip of the present invention, it further includes a welding module disposed on the body, the welding module being used to weld the spring contact to the outer shell.

[0007] As a preferred embodiment of the conductive spring contact welding fixture for power strips of the present invention, the linear slide module is configured as two sets, the two sets of linear slide modules are symmetrical to each other along their length direction, the linear slide module includes a sliding seat fixedly installed on the body and a sliding platform slidably installed on the sliding seat, and the power strip is placed on the sliding platform.

[0008] As a preferred embodiment of the conductive spring contact welding fixture for the power strip of the present invention, the clamping assembly includes four columns fixedly installed on the sliding platform and arranged in a rectangular shape, and a clamping frame is slidably installed on the four columns.

[0009] As a preferred embodiment of the conductive spring contact welding fixture for power strips of the present invention, the clamping assembly includes two hinge frames, and a fixed frame is installed between the corresponding two columns. The hinge frames are fixedly installed on the corresponding fixed frames. A clamping block is hinged on the hinge frame, and a hinge rod is hinged on the clamping block. The end of the hinge rod slides through the fixed frame and is fixedly installed with a reset plate. A reset spring is fixedly installed between the reset plate and the fixed frame, and the reset spring is sleeved on the outside of the hinge rod.

[0010] As a preferred embodiment of the conductive spring contact welding fixture for the power strip of the present invention, the control module includes a control board fixedly installed on the machine body, a control slot is provided on the control board, a slide rod is slidably installed in the control slot, a slide rail is slidably installed at the end of the slide rod, and the slide rail is fixedly connected to the drive frame.

[0011] As a preferred embodiment of the conductive spring contact welding fixture for the power strip of the present invention, the driving assembly includes a driving rod fixedly installed on the outside of the slide rod, a connecting frame fixedly installed at the end of the driving rod, and the connecting frame being fixedly connected to the clamping frame.

[0012] As a preferred embodiment of the conductive spring contact welding fixture for power strips of the present invention, the sliding platform has an internal hollow structure, the roller assembly includes several guide rods fixedly installed inside the sliding platform, a lifting plate is slidably installed on the outer side of the several guide rods, a roller part is fixedly installed on the lifting plate, several through openings are opened on the surface of the sliding platform, the openings are matched with the size of the roller part, and several return springs are fixedly installed inside the sliding platform, the return springs are sleeved on the outer side of the corresponding guide rods.

[0015] The beneficial effects of the conductive spring contact welding fixture for power strips of the present invention are as follows: In this application, by controlling the trajectory design of the groove and coordinating the combined motion of the slide bar and slide rail, the linear motion of the sliding platform itself is used as the driving source. This allows the actions of the clamping, clamping, and unloading components to be tied to the movement stroke of the sliding platform towards the upper / lower position or the welding position. This achieves the technical effect that the clamping and clamping actions are completed simultaneously during the movement towards the welding position, and the releasing and lifting actions are completed simultaneously during the movement towards the lower position. When the sliding platform reaches the welding position or the upper / lower position, the corresponding auxiliary actions are already in place. The welding module and the external unloading conveyor line can directly perform the operation without any waiting, thus completely avoiding the intermittent waiting time in the prior art where the sliding platform stops and then the actuator is triggered. This effectively improves the overall production capacity of the plug-in welding operation. Attached Figure Description

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Reference Figure 1 , Figure 2 , Figure 4 and Figure 12 This embodiment provides a spot welding fixture for power strips with conductive springs, which can improve the overall productivity of spot welding operations on power strips 2. It includes: a machine body 1; a linear slide module 3 mounted on the machine body 1 for supporting the power strip 2, wherein the power strip 2 is composed of a housing 22 and conductive springs 21 mounted on the housing 22; a positioning module 5 and a feeding module 6 mounted on the linear slide module 3; and a control module 7 mounted on the machine body 1 for controlling the operation of the positioning module 5 and the feeding module 6. Positioning module 5 includes a clamping component 51 and a driving component 53. The driving component 53 is used to drive the clamping component 51 to clamp the conductive spring 21 inside the housing 22 during the movement of the linear slide module 3 towards the welding position. Clamping component 52 is used to clamp the housing 22 simultaneously when the clamping component 51 clamps the conductive spring 21. Unloading module 6 includes a roller assembly 61 and a driving frame 62. The driving frame 62 is used to drive the roller assembly 61 to lift and unload the welded plug 2 during the movement of the linear slide module 3 to the upper / lower position, guided by the control module 7.

[0032] Reference Figure 1 , Figure 2 and Figure 3 It also includes a welding module 4 disposed on the body 1. The welding module 4 includes a multi-dimensional slide 41 disposed on the body 1 and a welding chuck 42. The welding chuck 42 is used to weld the spring piece 21 into the outer shell 22.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The linear slide module 3 is configured as two sets, and the two sets of linear slide modules 3 are symmetrical to each other along their length direction. The linear slide module 3 includes a sliding seat 31 fixedly installed on the body 1 and a sliding platform 32 slidably installed on the sliding seat 31. The plug bar 2 is placed on the sliding platform 32.

[0034] It should be noted that the multi-dimensional slide section 41 is used to drive the welding chuck 42 to move and position in multiple directions; when the linear slide module 3 drives the plug bar 2 into the welding position, since the positioning module 5 has completed the pre-pressing and pre-clamping of the spring 21 and the outer shell 22 during the movement, the welding chuck 42 can directly perform the welding action without waiting, thereby realizing the seamless connection between the welding module 4 and the positioning module 5 in terms of timing.

[0035] The sliding platforms 32 of the two sets of linear slide modules 3 are driven by independent drive sources, and they operate alternately: when one set of sliding platforms 32 carries the plug-in 2 and moves it towards the welding position for welding, the other set of sliding platforms 32 is in the loading / unloading position away from the welding position, performing unloading of plug-in 2 that has been welded and loading of plug-in 2 to be welded. The strokes of the two sets of sliding platforms 32 are staggered and they operate alternately, enabling the welding module 4 to work continuously without interruption.

[0036] Reference Figure 1 , Figure 4 , Figure 7 and Figure 9 The clamping assembly 51 includes four columns 511 fixedly installed on the sliding platform 32 and arranged in a rectangular shape, and a clamping frame 512 is slidably installed on the four columns 511.

[0037] Reference Figure 1 , Figure 4 , Figure 7 , Figure 9 and Figure 10 The clamping assembly 52 includes two hinge frames 521, and a fixed frame 526 is installed between the two corresponding columns 511. The hinge frames 521 are fixedly installed on the corresponding fixed frames 526. A clamping block 522 is hinged on the hinge frame 521, and a hinge rod 523 is hinged on the clamping block 522. The end of the hinge rod 523 slides through the fixed frame 526 and is fixedly installed with a reset plate 524. A reset spring 525 is fixedly installed between the reset plate 524 and the fixed frame 526. The reset spring 525 is sleeved on the outside of the hinge rod 523.

[0038] It should be noted that when the clamping frame 512 moves downward, its lower surface acts on the upper surface of the conductive spring 21, pressing the conductive spring 21 into the mounting slot of the housing 22, preventing the spring 21 from shifting due to vibration or heat during the welding process.

[0039] The clamping action of the clamping assembly 52 and the pressing action of the pressing assembly 51 are interconnected. Specifically, when the pressing frame 512 moves downward, its lower surface presses against the spring 21, and at the same time, the pressing frame 512 pushes the reset plate 524, causing the hinge rod 523 to drive the clamping block 522 to rotate around the hinge point of the hinge frame 521, so that the clamping block 522 fits against the outer wall of the outer shell 22, thereby clamping and fixing the outer shell 22. When the pressing frame 512 resets upward, the reset spring 525 releases its elastic potential energy, pushing the reset plate 524 and the hinge rod 523 to move in the opposite direction, driving the clamping block 522 to reset, releasing the clamping of the outer shell 22. By associating the clamping action of the clamping block 522 with the pressing action of the pressing frame 512, the pressing and clamping actions are completed synchronously without the need for an additional independent drive source.

[0040] Reference Figure 1 , Figure 4 , Figure 5 , Figure 8 and Figure 11 The control module 7 includes a control board 71 fixedly installed on the body 1. The control board 71 has a control groove 72. A slide rod 74 is slidably installed in the control groove 72. A slide rail 73 is slidably installed at the end of the slide rod 74. The slide rail 73 is fixedly connected to the drive frame 62. The control groove 72 is composed of a lower straight section 721, a long inclined section 724, an upper straight section 722, and a short inclined section 723 that are connected to each other.

[0041] Reference Figure 4 , Figure 7 , Figure 8 and Figure 9 The drive assembly 53 includes a drive rod 531 fixedly installed on the outside of the slide bar 74, and a connecting frame 532 fixedly installed at the end of the drive rod 531. The connecting frame 532 is fixedly connected to the clamping frame 512.

[0042] It should be noted that the trajectory shape of the control slot 72 is the core control logic of this application. The working principle will be explained in detail below in conjunction with the movement process of the slide module: When the sliding platform 32 carries the plug-in 2 and moves from the welding position to the upper / lower position, in the initial stage of movement, the slide rod 74 is located in the lower straight section 721 of the control groove 72. The clamping frame 512 and the clamping block 522 remain in a clamping / pressing state to ensure that the plug-in 2 will not loosen during the movement. When the slide rod 74 slides to the long inclined section 724, the slide rod 74 gradually rises during the sliding process along the long inclined section 724. Through the drive rod 531 and the connecting frame 532, the clamping frame 512 is driven to slide upward along the column 511, releasing the clamping of the spring piece 21. At the same time, the return spring 525 releases elastic potential energy, driving the clamping block 522 to rotate outward and reset, releasing the clamping of the outer shell 22. Then the slide rod 74 enters the upper straight section 722. At this time, the clamping frame 512 and the clamping block 522 are both in a fully released state. When the slide bar 74 slides to the end of the upper straight section 722, it will continue to slide and enter the uppermost position of the slide rail 73. Therefore, when the slide bar 74 slides along the short inclined section 723, it will start to drive the slide rail 73 and the drive frame 62 to move upward, thereby pushing the lifting plate 612 to rise along the guide rod 611. The roller part 613 extends out from the opening on the surface of the sliding platform 32 and lifts the completed plug bar 2 for unloading. When the sliding platform 32 carries the plug bar 2 and moves from the upper / lower position to the welding position, the process is reversed.

[0043] The trajectory design of the control groove 72 enables the slide bar 74 to complete one reciprocating motion within the control groove 72. The clamping and pressing are completed simultaneously during the feeding and welding strokes, and the releasing and lifting are completed simultaneously during the welding and unloading strokes. The entire process does not require any intermediate waiting or triggering of electrical signals, which greatly simplifies the action sequence.

[0044] Reference Figure 4 , Figure 6 and Figure 7 The sliding platform 32 has an internal hollow structure. The roller assembly 61 includes several guide rods 611 fixedly installed inside the sliding platform 32. A lifting plate 612 is slidably installed on the outer side of the several guide rods 611. A roller part 613 is fixedly installed on the lifting plate 612. Several through openings are opened on the surface of the sliding platform 32. The openings match the size of the roller part 613. Several return springs 614 are fixedly installed inside the sliding platform 32. The return springs 614 are sleeved on the outer side of the corresponding guide rods 611.

[0045] Reference Figure 4 , Figure 6 , Figure 7 and Figure 8 The drive frame 62 is U-shaped, and both ends of the drive frame 62 slide through the sliding platform 32 and are fixedly connected to the lifting plate 612.

[0046] It should be noted that the lifting height of the roller section 613 is limited by the vertical drop of the short inclined section 723. The design of this vertical drop must ensure that after the roller section 613 extends from the surface of the sliding platform 32, it pushes the bottom surface of the plug-in 2 away from the upper surface of the sliding platform 32. Furthermore, the height of several rollers of the roller section 613 decreases sequentially along the direction of the sliding platform 32 when moving to the upper / lower material position. In addition, the upper / lower material position of the linear slide module 3 is connected to the external unloading conveyor line. After being lifted, the plug-in 2 naturally slides into the unloading conveyor line due to the design of the decreasing height of the roller section 613. The second return spring 614 is compressed when the roller section 613 is lifted. When the drive frame 62 returns to its original position as the slide rod 74 descends, the second return spring 614 releases its elastic force to push the lifting plate 612 and the roller section 613 back to their original position, ensuring that the upper surface of the sliding platform 32 returns to a flat state, preparing for the next placement of the plug-in 2.

[0047] The U-shaped structure of the drive frame 62 semi-encloses the outer side of the sliding platform 32, and its two ends are symmetrically connected to both sides of the lifting plate 612, ensuring that the lifting plate 612 is subjected to uniform force during the lifting process. The drive frame 62 is fixedly connected to the slide rail 73, and the slide rail 73 is in sliding engagement with the slide rod 74, so that the slide rod 74 can both drive the slide rail 73 to move horizontally as a whole and slide relative to the slide rail 73 along its length.

[0048] In practical use, initially, one of the sliding platforms 32 is located at the upper / lower position, the clamping frame 512 on this sliding platform 32 is in the raised and released position, the clamping block 522 is kept open under the action of the return spring 525, the slide rod 74 is located at the end of the upper straight section 722, the roller assembly 61 retracts into the sliding platform 32, and the external robotic arm places the plug 2 to be welded on the sliding platform 32; then, the sliding platform 32 moves linearly along the sliding seat 31 towards the welding position under the drive of the drive source, and the slide rod 74 slides in the control groove 72; the sliding platform 32 moves Initially, the slide rod 74 slides horizontally along the upper straight section 722, and the clamping frame 512 remains in a loose state. When the slide rod 74 enters the long inclined section 724, as the sliding platform 32 continues to move towards the welding position, the slide rod 74 gradually descends along the inclined plane, thereby driving the clamping frame 512 to slide downward along the column 511 through the drive rod 531 and the connecting frame 532. The lower surface of the clamping frame 512 gradually presses the conductive spring piece 21 into the mounting slot of the outer shell 22. In addition, during this process, the slide rod 74 will slide within the slide rail 73, thus preventing the slide rail 73 from displacing in the vertical direction.

[0049] At the same time, as the clamping frame 512 moves downward, it simultaneously pushes the reset plate 524, causing the hinge rod 523 to slide and compress the reset spring 525, thereby causing the clamping block 522 to rotate inward around the hinge point. The end of the clamping block 522 gradually fits against the outer wall of the outer shell 22, clamping and fixing the outer shell 22. When the slide rod 74 moves to the end of the long inclined section 724, the clamping frame 512 has completely descended to the position to clamp the spring piece 21, and the clamping block 522 has also completely rotated to the position to clamp the outer shell 22. Meanwhile, the sliding platform 32 continues to slide to the end of the lower straight section 721 and reaches the welding position. During the entire journey to the welding position, the clamping and pressing actions are completed simultaneously along the way. When the sliding platform 32 reaches the welding position, the plug 2 has been completely fixed without any pause or waiting time for the fixture to move. Subsequently, the welding module 4 performs spot welding to weld the conductive spring piece 21 to the outer shell 22.

[0050] After welding, the sliding platform 32 carries the insert 2 and moves it from the welding position to the upper / lower position. When the slide rod 74 enters the long inclined section 724, as the sliding platform 32 continues to move to the upper / lower position, the slide rod 74 gradually rises along the inclined plane. Through the drive rod 531 and the connecting frame 532, it drives the clamping frame 512 to slide upward along the column 511, gradually releasing the pressure on the spring piece 21. At the same time, the return spring 525 releases its elastic potential energy to push the return plate 524 and the hinge rod 5 23 moves in the opposite direction, causing the clamping block 522 to rotate and reset, releasing the clamping of the outer shell 22; when the slide rod 74 moves to the end of the long inclined section 724 and enters the upper straight section 722, the clamping frame 512 has fully risen and reset, and the clamping block 522 has fully opened and reset. As the slide rod 74 moves to the end of the upper straight section 722, the slide rod 74 is at the uppermost end of the slide rail 73, and its vertical movement can no longer be compensated by its own sliding on the slide rail 73. Therefore, the slide rod 74 Continuing the movement, the device enters the short inclined section 723. As the slide bar 74 slides along the short inclined section 723, it drives the slide rail 73 to move upward, thereby driving the lifting plate 612 to move synchronously through the drive frame 62. This, in turn, drives the roller assembly 61 to completely lift the plug 2, which has completed the spot welding operation, off the surface of the sliding platform 32. At the same time, the upper / lower material position connects with the external unloading conveyor line. The height of the roller part 613 decreases sequentially along the direction of the sliding platform 32 moving to the upper / lower material position. After the plug 2 is lifted, it automatically slides into the unloading conveyor line under the action of gravity to complete the unloading, without the need for additional material handling or waiting time. Subsequently, the sliding platform 32 moves towards the welding position again, the slide bar 74 re-enters the upper straight section 722, the drive frame 62 descends under the action of the slide bar 74, the roller assembly 61 resets and retracts, the upper surface of the sliding platform 32 returns to flatness, and the external robotic arm places the new plug 2 to be welded on the surface of the sliding platform 32 for the next round of spot welding operation.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
