Description

Technical Field

[0001] The invention relates to the technical field of electronic manufacturing, in particular to electronic connector welding processing equipment. Background Art

[0002] As an indispensable part of electronic equipment, devices and systems, the demand for connectors continues to rise with the popularization of social economy and 5G technology. As an important way to connect connectors to wires, pressure welding technology has undergone a transformation from welding to crimping to adapt to high-temperature applications and the need for simple and reliable on-site services.

[0003] The existing connector welding technology is to align the wires with the welding holes on the connector one by one, and then use a pressure welding machine to weld the wires to the connector through welding pressure. Before welding pressure, the staff needs to align the wires to be welded with the welding holes on the connector one by one, which makes the welding pressure work cumbersome and is not conducive to the staff to complete the welding work efficiently. The sliding base of the existing welding processing equipment is fixedly molded for connectors of fixed sizes. When connectors of different sizes need to be welded, the mold or even the equipment needs to be replaced, making the welding adaptability relatively single.

The L-shaped groove is symmetrically opened on the outer wall of the flip cover. The limiting roller is slidably connected to the inside of the L-shaped groove. The two ends of the limiting roller are symmetrically fixedly connected to the gear ring outside the flip cover. The outside of the pressure plate is symmetrically fixedly connected to a gear plate that meshes with the gear ring.

[0008] Preferably, a pressure gun is installed on the welding device body, and a thermal fuse is slidably connected to the outer wall of the welding device body and located below the pressure gun.

[0010] Preferably, the height adjustment mechanism also includes a support plate fixedly connected to the side of the limiting vertical plate close to the positioning plate, the interior of the support plate is rotatably connected to a transmission gear, the middle part of the transmission gear is slidably connected to a slide rod, the bottom of the support plate is fixedly connected to the limiting bin, a fourth spring is fixedly connected between the bottom of the slide rod and the lower surface of the support plate, and the interior of the support plate is symmetrically slidably provided with a clamping plate meshing with the transmission gear.

[0011] Preferably, a folding groove is provided on the top of the flip cover, and a limiting round rod sliding inside the folding groove is fixedly connected to the outer wall of the pressure rod.

[0012] Preferably, the lower surface of the corrugated plate is wavy, and straight slots are provided on both sides of the corrugated plate, and the corrugated plate is movably connected to the inside of the flip cover through the straight slots.

[0013] Preferably, a connector is placed above the support plate, an electric wire is placed above the connector, a trapezoidal groove is opened on the outer wall of the limiting roller, the narrowest part of the trapezoidal groove is equal to the diameter of the electric wire, and the lower surface of the cross plate and the outer wall of the limiting roller are coated with a magnetic layer with the reverse magnetic coating.

The trapezoidal groove opened on the limiting roller makes the contact surface of the limiting roller with the wire narrower during rotation, so that the position of the wire is adjusted under the action of the rotation of the limiting roller, so that the end of the wire close to the connector is inserted into the welding hole of the connector, and the staff does not need to clamp the wires with the connector welding holes one by one, so that after pressing the pressure plate once, the multiple wires can be aligned with the welding holes of the connector together, thereby improving the welding efficiency.

[0017] 2. After placing the connector on the pallet, the connector's own weight presses the slide bar downward, and the protrusion on the outer wall of the slide bar slides on the inner wall of the transmission gear to drive the transmission gear to rotate. The transmission gear drives the clamping plate engaged with it to clamp and fix the connector, thereby improving the stability of the connector when it is press-welded with the wire. The clamping of the clamping plate is achieved by pressing down the connector's own weight, so that connectors of different sizes can be used on the pallet, avoiding the problem of damage to the connector caused by excessive clamping force of the clamping plate. The handle is pulled up by the staff and then slides up and down on the side wall of the limiting vertical plate, so that the pallet can be adjusted according to the thickness of different connectors, so that the welding hole on the connector remains in line with the axis of the half hole on the positioning plate, ensuring that the wire remains stable and does not shake when the hot fuse is press-welded to the wire, ensuring the stability of the connector and the wire after press-welding, and improving the welding ability of the equipment for connectors of different sizes.

[0041] A folding groove 414 is formed on the top of the flip cover 413 , and a limiting round rod that slides inside the folding groove 414 is fixedly connected to the outer wall of the pressing rod 416 .

[0042] The lower surface of the corrugated plate 418 is wavy, and straight slots are provided on both sides of the corrugated plate 418 . The corrugated plate 418 is movably connected to the inside of the flip cover 413 through the straight slots.

[0043] A connector is placed above the support plate 437, and an electric wire is placed above the connector. A trapezoidal groove is opened on the outer wall of the limiting roller 423, and the narrowest part of the trapezoidal groove is equal to the diameter of the electric wire. The lower surface of the cross plate 421 and the outer wall of the limiting roller 423 are coated with a magnetic coating with opposite magnetic poles.

[0044] The outer wall of the slide rod 439 is fixedly connected with a protrusion 4312 , and the inner wall of the transmission gear 438 is provided with a threaded groove matched with the protrusion 4312 . The slide rod 439 is limited by the limiting bin 4311 and slides inside the limiting bin 4311 .

[0045] The above implementation works as follows:

[0046] The initialization steps are as follows:

[0047] The first spring 419 is in an unstretched state, the second spring 4110 is in an uncompressed state, the limiting round rod does not slide downward into the folding groove 414, the fourth spring 4310 is in an unstretched state, the tooth plate 425 is not engaged with the tooth ring 424, and the sliding rod 439 slides out from above the support plate 437.

[0048] The working steps are as follows:

[0049] The wires are positioned by the wire flattening mechanism 41 and the wire positioning mechanism 42:

[0050] The staff will place multiple wires on the top of the positioning plate 412, and then flip the cover 413 to cover the top of the wires, and then the staff will press the pressure plate 415 downward. After the pressure plate 415 moves downward, it drives the pressure rod 416 connected to the bottom to move downward together. During the downward movement of the pressure rod 416, the limiting round rod on the outer wall of the pressure rod 416 will slide into the folding groove 414. As the limiting round rod on the outer wall of the pressure rod 416 moves downward in the folding groove 414, the pressure rod 416 will pass The cylinder 417 drives the corrugated plate 418 to move downward in a swinging manner inside the pressing plate 415. During the downward movement of the corrugated plate 418, the first spring 419 is stretched and elastically extended. The wires below the corrugated plate 418 are affected by the wavy fluctuations of the lower surface of the corrugated plate 418 and the reciprocating swing of the corrugated plate 418, so that multiple wires are laid one by one on the top of the positioning plate 412 under the action of the corrugated plate 418. During the above working process, the movement of the corrugated plate 418 and the pressing plate 415 is synchronous.

[0051] The downward movement of the corrugated plate 418 will push the limiting roller 423 to slide downward inside the L-shaped groove 422. When the corrugated plate 418 slides to the bottom inside the flip cover 413, the corrugated plate 418 cannot continue to move downward and forms a limit for the wire and the limiting roller 423. At this time, the staff continues to press the pressing plate 415 downward. Because the corrugated plate 418 cannot move, the second spring 4110 is squeezed and elastically contracts. The pressing plate 415 moves downward and engages with the gear ring 424, causing the gear ring 424 to start rotating. The rotation of the gear ring 424 causes the limiting roller 423 to start rotating. During the rotation process, the limiting roller 423 adjusts the position of the wire through the trapezoidal groove opened on its outer wall, so that the wires are connected to the welding holes of the connector one by one.

[0052] The limiting round rod on the side wall of the pressure rod 416 slides downward inside the folding groove 414, so that the positioning plate 412 swings and presses down the multiple wires below it, so that the wire harness is dispersed and fits one by one to the upper surface of the positioning plate 412 under the swinging and squeezing action of the corrugated plate 418, avoiding the problem of the wire harness bending and entanglement with each other when the staff welds multiple wires, and facilitating the staff to align the multiple wires and pressure weld them together. Through the trapezoidal groove opened on the limiting roller 423, the contact surface between the limiting roller 423 and the wire becomes narrower during rotation, so that the position of the wire is adjusted under the action of the rotation of the limiting roller 423, so that the end of the wire close to the connector is inserted into the welding hole of the connector, and the staff does not need to clamp the wires with the connector welding hole one by one, so that after pressing the pressure plate 415 once, the multiple wires can be aligned with the welding hole of the connector together, thereby improving the welding efficiency.

[0053] Connectors of different sizes are fixed by means of a height adjustment mechanism 43:

[0054] The staff will place the connector on the support plate 437. After the connector is placed on the slide bar 439, it will press the slide bar 439 downward. During the downward sliding process of the slide bar 439, the protrusion 4312 on the side wall of the slide bar 439 will slide in the thread groove of the transmission gear 438. The transmission gear 438 will rotate due to the sliding of its inner wall and the protrusion 4312. The rotation of the transmission gear 438 drives the two clamping plates 4313 meshing with each other to slide relatively close to each other inside the support plate 437. During the sliding process, the clamping plates 4313 clamp the two sides of the connector, so that connectors of different sizes can all remain stable during welding.

[0055] Then the staff pulls the handle 435 to the side away from the slide plate 432, and the third spring 436 is stretched and elastically extended. After the handle 435 is pulled out, the card plate 434 is no longer engaged with the slot 433. The staff pulls the handle 435 and moves it up and down, so that the card plate 434 drives the slide plate 432 to slide up and down inside the limiting vertical plate 431, and adjusts the horizontal height of the connector placed on the support plate 437 so that the welding hole on the connector is in line with the axis of the half hole on the positioning plate 412. When the position adjustment is completed, the staff stops pulling the handle 435, the third spring 436 elastically contracts and causes the card plate 434 to re-engage with the slot 433, thereby fixing the position of the slide plate 432 inside the limiting vertical plate 431.

[0056] After the connector is placed on the support plate 437, the connector's own weight presses the slide bar 439 downward, and the protrusion 4312 on the outer wall of the slide bar 439 slides on the inner wall of the transmission gear 438 to drive the transmission gear 438 to rotate, and the transmission gear 438 drives the clamping plate 4313 engaged with it to clamp and fix the connector, thereby improving the stability of the connector when it is pressure-welded with the wire. The clamping plate 4313 is clamped by the connector's own weight, so that connectors of different sizes can be used on the support plate 437, avoiding the problem of damage to the connector caused by excessive clamping force of the clamping plate 4313. After the handle 435 is pulled by the staff, it slides up and down on the side wall of the limiting vertical plate 431, so that the support plate 437 can be adjusted according to the thickness of different connectors, so that the welding hole on the connector remains in line with the axis of the half hole on the positioning plate 412, ensuring that when the hot fuse 5 is pressure-welded to the wire, the wire remains stable and does not shake, ensuring the stability of the connector and the wire after pressure welding, and improving the welding ability of the equipment for connectors of different sizes.

[0057] After the connector and the wiring harness are fixed, the staff operates to slide the thermal fuse 5 toward the direction of the wire and heat it, and moves the pressure gun 2 downward, and the pressure gun 2 pressure welds the wire through the thermal fuse 5.
