Description

Technical Field

[0001] The invention relates to the technical field of spring piece welding, in particular to a hardware spring piece welding wire device. Background Art

[0002] Metal shrapnel welding is a key electrical connection process, which is widely used in a variety of electronic products such as mobile phone cards, antennas, membrane switches, contact switches, PCB boards, FPC boards, medical devices, headphone jacks, connectors, micro motors, sensors, relay switches, digital 3C products and automotive instrument touch switches. This process uses a hot melt welding machine to accurately connect the metal shrapnel and the wire to ensure the stable transmission of electrical signals. When welding the metal shrapnel, first place the metal shrapnel and the wire on the support fixture so that the ends of the metal shrapnel and the wire are in contact. This step requires ensuring that the position of the metal shrapnel and the wire is accurate for subsequent welding operations, and then use a hot melt welding machine to weld the contact part. During the welding process, the hot melt welding machine will generate high temperature to melt the contact part of the metal shrapnel and the wire and combine them together.

[0003] In the actual hardware wire welding operation, the copper wire is placed on the welding table by the staff manually. However, this manual operation process can easily lead to deviations in the placement of the copper wire and the shrapnel. When the staff manually place the copper wire, they need to rely on visual judgment and the accuracy of hand movements. In addition, long-term work may cause fatigue, making it difficult to reliably guarantee the accuracy of each placement. This series of factors often leads to uneven quality of the shrapnel after welding, thus affecting the quality of the final product. For this reason, we propose a hardware shrapnel wire welding device. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1-Figure 10 The present invention provides a technical solution: a hardware shrapnel welding wire device, comprising a welding seat 1, a welding machine body 2 and a welding platform 11. The working mode of the welding machine body 2 is that the welding frame drives the welding gun to descend to a certain distance, and then the welding gun descends to weld the shrapnel. This is the prior art, so no further description is made. It also includes a loading column 12, which is installed on the welding machine body 2, and a plurality of conveying grooves 13 are opened on the loading column 12, and the plurality of conveying grooves 13 are arranged in a circle; and the diameter of the conveying groove 13 is consistent with that of the copper wire, and a shrapnel conveyor belt 14, which is installed on the welding seat 1, and a plurality of shrapnel conveyor belts 14 are provided, and the plurality of shrapnel conveyor belts 14 are used to clamp the hardware shrapnel.

[0033] The driving unit 3 is arranged on the welding seat 1, and the loading column 12 is arranged on the driving unit 3. The driving unit 3 is used to drive the loading column 12 to rotate and synchronously drive the conveying trough 13 to rotate, so as to move the copper wire falling into the conveying trough 13 to a designated position on the welding table 11 to wait for welding.

[0034] The design of the drive unit 3 brings many significant advantages. By cleverly combining the loading column 12 and the conveying trough 13, the design realizes the automatic sorting and individual separation of the copper wires during the rotation process, completely abandoning the steps of manual selection and placement, thereby greatly improving the welding efficiency. The conveying trough 13 adopts a circular arrangement to ensure that each copper wire can be placed in a predetermined position, which provides great convenience for the welding of the welding machine body 2.

[0035] The precise control of the drive unit 3 and the loading column 12 ensures that the copper wire can be accurately moved to the specified position on the soldering station 11. This positioning design not only effectively reduces the position deviation during the welding process, but also significantly improves the welding quality and consistency.

[0036] In addition, the design also demonstrates high flexibility, and can easily adapt to copper wires of different specifications and lengths. Automatic loading and conveying of copper wires of different sizes can be achieved by simply adjusting the parameters of the drive unit 3 and the loading column 12. This feature undoubtedly greatly enhances the adaptability of the production line, enabling it to calmly cope with diverse production needs.

[0037] The shrapnel supply unit 6 is arranged on the welding seat 1, and the shrapnel conveyor belt 14 is arranged on the shrapnel supply unit 6. The shrapnel supply unit 6 is used to drive the shrapnel conveyor belt 14 to rotate, thereby pushing the hardware shrapnel located between the multiple shrapnel conveyor belts 14 to move.

[0038] The advantage of setting up the shrapnel supply unit 6 is that the shrapnel conveyor belt 14 can be used to move the shrapnel to the specified position during welding, which not only ensures the high-precision alignment of the welding point, but also effectively avoids poor welding caused by position deviation, such as loose welding, cold welding or welding misalignment, thereby significantly improving the overall quality and reliability of welding. At the same time, the design can continuously and stably complete the positioning task of the shrapnel and the copper wire without manual intervention, so that the consistency of the welding results is also significantly improved.

[0039] The design of the deflection member 10 allows the welding wire device to switch between perforation welding and plane fitting welding. In actual production, the demand for spring piece welding may vary depending on the product type, specification or customer requirements. This design can easily adapt to these changes. Not only that, in actual production, the demand for spring piece welding may vary depending on the product type, specification or customer requirements. This design can easily adapt to these changes, greatly improving the utilization rate of the equipment.

[0040] The driving unit 3 includes a conveying member 4 disposed on the welding seat 1, and the copper wire is moved to the welding table 11 by means of the conveying member 4. The conveying member 4 is provided with a driving member 5, and the driving member 5 is used to provide power for the conveying member 4 to work.

[0041] The conveying member 4 includes a conveying block 41 arranged on the welding seat 1, and a storage bin 42 is opened on the conveying block 41. A rotating bin 43 is opened in the conveying block 41, and the rotating bin 43 is connected with the storage bin 42. A rotating shaft 44 is rotatably arranged in the rotating bin 43, and one end of the rotating shaft 44 is located in the rotating bin 43 and is connected to the loading column 12 through a one-way bearing.

[0042] The advantage of the conveyor 4 is that it can accurately move the copper wire to a pre-set precise position. This ability not only ensures high-precision alignment of the welding points, but also effectively avoids poor welding caused by position deviations, such as loose welding, cold welding or welding misalignment, thereby significantly improving the overall quality and reliability of welding.

[0043] The driving member 5 includes a driving shaft 51 slidably arranged on the side wall of the rotating bin 43, a moving plate 52 is arranged at one end of the driving shaft 51 located inside the rotating bin 43, the moving plate 52 is half-moon-shaped, a wire outlet hole 57 for use with the moving plate 52 is opened on the rotating bin 43, a driving rod 53 is arranged on the driving shaft 51, a spiral groove 54 is arranged at one end of the rotating shaft 44 located outside the rotating bin 43, the driving rod 53 is slidably connected with the spiral groove 54, a pressing cap 55 is arranged on the driving rod 53, a protective shell 56 is arranged on the conveying block 41, and the protective shell 56 is movably connected with the driving rod 53 and the pressing cap 55.

[0044] Before welding, the staff first puts the sorted copper wire for welding into the storage bin 42, then pulls the pressing cap 55 to drive the push shaft 51 and the push rod 53 to move synchronously. When the push rod 53 moves, the spiral groove 54 connected to it is slidably connected to drive the rotating shaft 44 to rotate. The rotation of the rotating shaft 44 drives the loading column 12 to rotate. During the rotation of the loading column 12, the copper wire will fall from the storage bin 42 into the conveying trough 13 under the action of gravity. At the same time, because the diameter of the conveying trough 13 is consistent with that of the copper wire, each Only a single copper wire will enter the conveying trough 13 each time. When the position of the copper wire is consistent with the wire outlet hole 57, the staff pushes the pressing cap 55 in the reverse direction, so that the copper wire is pushed out of the rotating bin 43 by the moving plate 52 and moves to the soldering station 11. Because one end of the rotating shaft 44 is located in the rotating bin 43 and is connected to the loading column 12 through a one-way bearing, pushing the pressing cap 55 will not drive the loading column 12 to rotate, and due to the semi-lunar design of the moving plate 52, it will not block the rotation of the loading column 12 during the movement.

[0045] The shrapnel supply unit 6 includes a mounting member 7 arranged on the welding seat 1, and the mounting member 7 is used to install and fix the shrapnel conveyor belt 14. The mounting member 7 is provided with a displacement member 8, and the displacement member 8 is used to drive the shrapnel conveyor belt 14 to rotate and synchronously drive the shrapnel to move. The welding machine body 2 is provided with a power member 9, and the power member 9 is used to provide power for the displacement member 8. The mounting member 7 is provided with a deflection member 10, and the deflection member 10 is used to drive the shrapnel conveyor belt 14 to deflect.

[0046] The mounting member 7 includes a mounting plate 71 arranged on the welding seat 1, a mounting shaft 72 is rotatably arranged on the mounting plate 71, a fixing plate 73 is arranged on the mounting shaft 72, the fixing plate 73 is L-shaped, a plurality of rotating shafts 74 are rotatably arranged on the fixing plate 73, a toothed pulley 75 is arranged on the rotating shaft 74, a toothed belt 76 is arranged on the toothed belt pulley 75, the toothed belt 76 is connected to the spring conveyor belt 14, a sorting bin 77 is arranged on the welding seat 1, a sliding plate 78 is slidably arranged in the sorting bin 77, an extrusion spring 79 is arranged on one side of the sliding plate 78, one end of the extrusion spring 79 is connected to the sorting bin 77, a sealing cover 710 is arranged on the sorting bin 77, and the sealing cover 710 is interference fit with the sorting bin 77.

[0047] The displacement member 8 includes a transmission shaft 81 rotatably arranged on the welding seat 1, a transmission gear 82 is arranged on the transmission shaft 81, an extension rod 83 is arranged on the mounting plate 71, a positioning shaft 84 is rotatably arranged on the extension rod 83, a transmission gear 85 meshing with the transmission gear 82 is arranged on the positioning shaft 84, a worm 86 is arranged on the positioning shaft 84, a worm wheel 87 meshing with the worm 86 is arranged on the rotating shaft 74, the worm wheel 87 is connected to the rotating shaft 74 through a one-way bearing, and a plurality of rotating shafts 74 are provided with reversing gears 88 meshing with each other, a mounting rod 89 is arranged on the sorting bin 77, a driving plate 810 is slidably arranged on the mounting rod 89, a pushing plate 811 is arranged on the driving plate 810, and the pushing plate 811 is slidably connected to the sorting bin 77, a moving screw rod 812 is arranged on the positioning shaft 84, and the moving screw rod 812 is threadedly connected to the driving plate 810.

[0048] The advantage of setting up the displacement member 8 is that the shrapnel conveyor belt 14 can be used to move the shrapnel to the specified position during welding, which not only ensures the high-precision alignment of the welding point, but also effectively avoids poor welding caused by position deviation, such as loose welding, cold welding or welding misalignment, etc., greatly improving the overall quality and reliability of welding. At the same time, the design can continuously and stably complete the positioning task of the shrapnel and the copper wire without manual intervention, so that the consistency of the welding results is also significantly improved.

[0049] The power component 9 includes a power bin 91 arranged on the welding seat 1, a piston plate is slidably arranged in the power bin 91, a power spring 93 is arranged in the power bin 91, one end of the power spring 93 is connected to the piston plate, an extrusion rod 94 is arranged on the piston plate, the extrusion rod 94 is slidably connected to the power bin 91, an extrusion rod 95 used in conjunction with the extrusion rod 94 is arranged on the welding machine body 2, a power tube 96 is arranged in the power bin 91, a piston plate 97 is slidably arranged in the power tube 96, a power shaft 98 is arranged on the piston plate 97, the power shaft 98 is slidably connected to the power tube 96, a power rack 99 is arranged on the power shaft 98, and a power gear 910 engaged with the power rack 99 is arranged on the transmission shaft 81.

[0050] The deflection member 10 includes a triangular block 101 arranged on the power rack 99, a lifting rod 102 is arranged on the welding seat 1, a deflection rack 103 is slidably arranged on the lifting rod 102, a deflection gear 1010 engaged with the deflection rack 103 is arranged on the mounting shaft 72, a return spring 104 is sleeved on the lifting rod 102, a limiting plate 105 is arranged on the lifting rod 102, a lifting rod 106 is arranged on the deflection rack 103, a switching groove 107 is opened on the lifting rod 106, a switching rod 108 is slidably arranged in the switching groove 107, and a fixing bolt 109 used in conjunction with the switching rod 108 is arranged on the lifting rod 106.

[0051] The benefit of the deflector 10 is that it allows the wire welding device to switch between perforation welding and flat fitting welding. In actual production, the requirements for spring welding may vary depending on product type, specification or customer requirements, and this design can easily adapt to these changes.

[0052] When the welding frame in the welding machine body 2 descends, the extrusion rod 2 95 is synchronously driven to descend. The extrusion rod 2 95 descends to squeeze the extrusion rod 1 94, and synchronously drives the piston plate 1 92 to move, thereby squeezing the gas in the power bin 91. At this time, the gas enters the power tube 96 under the push, and pushes the piston plate 2 97 in the power tube 96 to move. The movement of the piston plate 2 97 drives the power shaft 98 and the power rack 99 connected to the power shaft 98 to move. The movement of the power rack 99 drives the power gear 910 engaged with it to rotate.

[0053] The power gear 910 rotates to drive the transmission shaft 81, and the transmission shaft 81 rotates to drive the transmission gear 1 82 disposed thereon to rotate. The transmission gear 1 82 rotates to drive the transmission gear 2 85 engaged therewith to rotate. The transmission gear 2 85 rotates to drive the positioning shaft 84 to rotate synchronously. The positioning shaft 84 rotates to drive the worm 86 disposed thereon to rotate synchronously. The worm 86 rotates to drive the worm wheel 87 disposed on the rotating shaft 74 to rotate synchronously. The worm wheel 87 rotates to drive the rotating shaft 74 to rotate, and synchronously drives multiple rotating shafts 74 to rotate synchronously through the reversing gear 88. The rotating shaft 74 rotates to drive the toothed belt pulley 75 to rotate. The toothed belt pulley 75 rotates to drive the toothed belt 76 to rotate. The toothed belt 76 rotates and drives the spring sheet conveyor belt 14 arranged thereon to rotate, thereby driving the spring sheet to move. The positioning shaft 84 rotates and drives the movable screw rod 812 connected thereto to rotate. The movable screw rod 812 rotates and drives the driving plate 810 threadedly connected thereto to move. The driving plate 810 moves and drives the pushing plate arranged thereon to extend into the sorting bin 77, pushing the spring sheet in the sorting bin 77 to between the two spring sheet conveyor belts 14, so that the spring sheet moves under the drive of the conveyor belt. When the welding machine body 2 rises, the pushing plate 811 is reset under the reverse rotation of the movable screw rod 812, and the spring sheet in the sorting bin 77 will continue to rise under the action of the extrusion spring 79.

[0054] When it is necessary to change the welding method to perforation welding, the staff first turns the fixing bolt 109 to release the fixation of the switching rod 108, and then pulls the switching rod 108 out so that it can contact the triangular block 101. After completion, the switching rod 108 is fixed again with the bolt. When the triangular block 101 moves with the power rack 99, when it moves to the specified position, the triangular block 101 will push the lifting rod 106 to rise, and synchronously drive the deflection rack 103 to rise. The rise of the deflection rack 103 drives the deflection gear 1010 engaged with it to rotate, and the rotation of the deflection gear 1010 drives the fixed plate 73 to rotate, thereby driving the shrapnel conveyor belt 14 to deflect, so that the shrapnel is in a tilted state, and then the copper wire is controlled to pass through the opening on the shrapnel. After completion, the welding gun is lowered for welding.

[0055] When in use, before welding, the staff first puts the sorted copper wire for welding into the storage bin 42, then pulls the pressing cap 55 to drive the pushing shaft 51 and the pushing rod 53 to move synchronously. When the pushing rod 53 moves, the spiral groove 54 slidably connected thereto drives the rotating shaft 44 to rotate, and the rotation of the rotating shaft 44 drives the loading column 12 to rotate. During the rotation of the loading column 12, the copper wire will fall from the storage bin 42 into the conveying trough 13 under the action of gravity. At the same time, because the diameter of the conveying trough 13 is consistent with that of the copper wire, Only a single copper wire will enter the conveying trough 13 each time. When the position of the copper wire is consistent with the wire outlet hole 57, the staff pushes the pressing cap 55 in the reverse direction, so that the copper wire is pushed out of the rotating bin 43 by the moving plate 52 and moves to the soldering station 11. Because one end of the rotating shaft 44 is located in the rotating bin 43 and is connected to the loading column 12 through a one-way bearing, pushing the pressing cap 55 will not drive the loading column 12 to rotate, and due to the semi-lunar design of the moving plate 52, it will not block the rotation of the loading column 12 during the movement.

[0056] When the welding frame in the welding machine body 2 descends, the extrusion rod 2 95 is synchronously driven to descend. The extrusion rod 2 95 descends to squeeze the extrusion rod 1 94, and synchronously drives the piston plate 1 92 to move, thereby squeezing the gas in the power bin 91. At this time, the gas enters the power tube 96 under the push, and pushes the piston plate 2 97 in the power tube 96 to move. The movement of the piston plate 2 97 drives the power shaft 98 and the power rack 99 connected to the power shaft 98 to move. The movement of the power rack 99 drives the power gear 910 engaged with it to rotate.

[0057] The power gear 910 rotates to drive the transmission shaft 81, and the transmission shaft 81 rotates to drive the transmission gear 1 82 disposed thereon to rotate. The transmission gear 1 82 rotates to drive the transmission gear 2 85 engaged therewith to rotate. The transmission gear 2 85 rotates to drive the positioning shaft 84 to rotate synchronously. The positioning shaft 84 rotates to drive the worm 86 disposed thereon to rotate synchronously. The worm 86 rotates to drive the worm wheel 87 disposed on the rotating shaft 74 to rotate synchronously. The worm wheel 87 rotates to drive the rotating shaft 74 to rotate, and synchronously drives multiple rotating shafts 74 to rotate synchronously through the reversing gear 88. The rotating shaft 74 rotates to drive the toothed belt pulley 75 to rotate. The toothed belt pulley 75 rotates to drive the toothed belt 76 to rotate. The toothed belt 76 rotates and drives the spring sheet conveyor belt 14 arranged thereon to rotate, thereby driving the spring sheet to move. The positioning shaft 84 rotates and drives the movable screw rod 812 connected thereto to rotate. The movable screw rod 812 rotates and drives the driving plate 810 threadedly connected thereto to move. The driving plate 810 moves and drives the pushing plate arranged thereon to extend into the sorting bin 77, pushing the spring sheet in the sorting bin 77 to between the two spring sheet conveyor belts 14, so that the spring sheet moves under the drive of the conveyor belt. When the welding machine body 2 rises, the pushing plate 811 is reset under the reverse rotation of the movable screw rod 812, and the spring sheet in the sorting bin 77 will continue to rise under the action of the extrusion spring 79.

[0058] When it is necessary to change the welding method to perforation welding, the staff first turns the fixing bolt 109 to release the fixation of the switching rod 108, and then pulls the switching rod 108 out so that it can contact the triangular block 101. After completion, the switching rod 108 is fixed again with the bolt. When the triangular block 101 moves with the power rack 99, when it moves to the specified position, the triangular block 101 will push the lifting rod 106 to rise, and synchronously drive the deflection rack 103 to rise. The rise of the deflection rack 103 drives the deflection gear 1010 engaged with it to rotate, and the rotation of the deflection gear 1010 drives the fixed plate 73 to rotate, thereby driving the shrapnel conveyor belt 14 to deflect, so that the shrapnel is in a tilted state, and then the copper wire is controlled to pass through the opening on the shrapnel. After completion, the welding gun is lowered for welding.

[0059] Example 2: Please refer to Fig.11 The present invention provides a technical solution: a protective cover 15 is provided on the storage bin 42, and the protective cover 15 is interference fit with the storage bin 42. A transparent observation window 16 is provided on the protective cover 15. The design of the protective cover 15 can prevent welding slag from splashing into the storage bin 42 during welding and contaminating the copper wire in the storage bin 42. The setting of the observation window 16 allows the staff to observe the amount of copper wire in the storage bin 42, so as to add the copper wire in time.
