[0002] The signal transmission of the display screen is mainly carried out through display terminals, and the display terminals are mainly electrically connected to the main board of the display screen through wires. Therefore, during the production process of the display screen, a soldering machine is required to solder multiple terminal wires to the metal contacts of the main board. A soldering machine is a device used for welding electronic components. It heats the solder wire to melt it and then welds the electronic components to the circuit board.

[0003] The welding of the terminal wires on the main board of the display screen mainly adopts the method of pressure welding. In the traditional welding process, the ends of the terminal wires are peeled and fixed in rows. A soldering flux (mainly rosin) is applied to the metal contacts of the main board, and then tin wire is placed on the row of terminal wires (either manually placing a section of tin wire or supplying tin wire by a tin wire conveyor, which automatically breaks after melting when the pressure welding is completed). Finally, the soldering machine is used for pressure welding and heating for welding. In the traditional welding device, multiple sets of equipment are required for operations such as peeling the terminal wires, positioning the terminal wires, applying tin, and applying the soldering flux, resulting in low efficiency and being unable to meet the requirements of automatic continuous processing.

[0039] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] Embodiment, according to Figure 1 — Figure 11 ,like Figure 1 In the embodiment of the present invention, a welding device for display screen manufacturing includes a bonding head 1, a welding table 2, a wire rack 3 for placing a wire coil and a tin wire coil, a first driving frame 4, a second driving frame 7, and a T-shaped driving frame 9. The bonding head 1 is arranged directly above one end of the welding table 2, and the first driving frame 4 is fixedly installed on the top of the welding table 2 and is located between the wire rack 3 and the bonding head 1. The device also includes:

[0042] A wire cutting assembly 5 provided between the first driving frame 4 and the welding head 1 for cutting the wire;

[0043] A wire stripping assembly 6 provided between the wire cutting assembly 5 and the welding head 1 for stripping the wire;

[0044] The fluxing assembly 8 is provided between the wire stripping assembly 6 and the bonding head 1 .

[0045] like Figure 1In it, a limiting groove is formed on the T-shaped driving frame 9. Both ends of the pressure welding head 1 are fixedly installed with first driving rods 101. The first driving rods 101 and the fourth driving rods 503 are both slidably installed in the limiting groove inside the T-shaped driving frame 9. A wire stripping rod 901 is integrally formed at the bottom of the T-shaped driving frame 9. The wire stripping rod 901 is placed between the tin wire and the peeled wire. Among them, when the pressure welding head 1 presses down for pressure welding, through the sliding action of the first driving rod 101 and the limiting groove on the T-shaped driving frame 9, the first driving rod 101 moves downward to drive the T-shaped driving frame 9 to rotate (rotate towards the pressure welding head 1 side). The rotation of the T-shaped driving frame 9 can drive the wire cutting assembly 5 to rise, and at the same time, the height of the wire stripping rod 901 drops to press and separate the wire from the soldering flux assisting assembly 8 after wire cutting is completed.

[0046] As Figure 2 In it, the wire rack 3 is fixedly installed on the top of the welding table 2 on the side far from the pressure welding head 1. Two placing rods 301 are rotatably installed on the wire rack 3. A plurality of rollers 302 for placing wire reels or tin wire reels are respectively sleeved on the two placing rods 301. The two placing rods 301 are arranged up and down. The rollers 302 on the upper placing rod (301) are sleeved with tin wire reels, and the rollers 302 on the lower placing rod 301 are sleeved with wire reels. A positioning cap 303 is threadedly installed at one end of the placing rod 301. Two second driving rods 401 and two third driving rods 402 are rotatably installed on the first driving frame 4. Driving wheels 403 are fixedly sleeved on the two third driving rods 402 and one of the second driving rods 401 corresponding to the positions of the rollers 302. A punching wheel 404 is fixedly sleeved on the other second driving rod 401 corresponding to the position of the roller 302. Among them, after unscrewing the positioning cap 303, the roller 302 can be taken off to replace the tin coil and the wire coil. After replacement, just tighten the positioning cap 303 to position the roller 302, which is convenient for replacing the tin coil and the wire coil after they are used up. From Figure 2 As shown, two motors for driving the second driving rod 401 and the third driving rod 402 to rotate are fixedly installed on the first driving frame 4. The tin wire is placed between the driving wheel 403 and the punching wheel 404, and the wire with a terminal and skin is placed between the two driving wheels 403. By driving the second driving rod 401 and the third driving rod 402 to rotate through the motor, the tin wire and the wire with a terminal and skin can be conveyed. During the conveying process of the tin wire, the punching wheel 404 rotates, and the teeth on the punching wheel 404 can be used to punch holes at intervals at the top of the tin wire for subsequent addition of soldering flux.

[0047] As Figure 3In it, the wire cutting assembly 5 includes a first slide rail 501, multiple pairs of tool holders 502, and a fourth driving rod 503. The first slide rail 501 is fixedly installed on the welding table 2. Multiple pairs of tool holders 502 are slidably installed on the first slide rail 501 in a mirror image manner. A plurality of hanging seats 504 are fixedly sleeved on the fourth driving rod 503. Two groups of first connecting rods 505 are rotatably installed between the hanging seats 504 and the tool holders 502 in a triangular shape. Among them, when the pressure welding head 1 presses down for welding, it drives the fourth driving rod 503 to move upward, and drives the two first connecting rods 505 to rotate (the included angle becomes smaller). The first connecting rods 505 drive the two tool holders 502 to approach each other to clamp and cut the insulated wire, so as to achieve the purpose of automatic wire cutting.

[0048] As Figure 4 In it, a plurality of wire guide plates 506 are fixedly installed on the first slide rail 501. The wire guide plates 506 are provided with holes for the tin wire and the insulated wire to pass through. The holes for the tin wire to pass through on the wire guide plates 506 are provided with bumps for grooving the tin wire. Among them, during the conveying process of the tin wire, it passes through the holes on the guide plate. Due to the bumps in the holes, the bottom of the tin wire will be pressed out with a card slot, so that the stripped wire core can be clamped into the card slot.

[0049] As Figure 5 and Figure 7 In it, the wire stripping assembly 6 includes a wire stripping table 601 and two second slide rails 602. The two second slide rails 602 are fixedly installed on the top of the welding table 2. The wire stripping table 601 is slidably installed on the tops of the two second slide rails 602. A first electric push rod 603 for driving the wire stripping table 601 to translate is rotatably installed between the second slide rails 602 and the wire stripping table 601. Two chutes are opened on the top of the wire stripping table 601, and a plurality of wire stripping seats 604 are slidably installed in the chutes. A wire stripping pliers 605 is fixedly installed on the wire stripping seats 604, and a convex rod 606 is provided at the bottom of the wire stripping seats 604. A plurality of driving disks 607 are rotatably installed in the wire stripping table 601. A second connecting rod 608 is rotatably installed between the driving disks 607 and the convex rod 606. A first gear 609 is fixedly installed on the shaft of the driving disk 607. A rack 611 meshing with the plurality of first gears 609 is slidably installed in the wire stripping table 601. A second electric push rod 610 for driving the rack 611 to translate is fixedly installed at one end of the wire stripping table 601. Among them, when the second electric push rod 610 extends, it pushes the rack 611 to translate and slide in the wire stripping table 601. The rack 611 drives the driving disk 607 to rotate through the meshing action with the first gear 609. The driving disk 607 rotates to drive the two wire stripping seats 604 to approach each other (under the limiting action of sliding on the wire stripping table 601), and the outer skin of the terminal wire is clamped and cut by the wire stripping pliers 605. After the outer skin is clamped and cut, the second electric push rod 610 extends to push the wire stripping table 601 to translate and slide on the second slide rails 602 (the second electric push rod 610 rotates while extending), so as to pull out the outer skin of the terminal wire from the wire core, achieving the purpose of automatic wire stripping of the terminal wire.

[0050] As Figure 5 and Figure 6 In [reference], a plurality of adjusting seats 612 are fixedly installed at the bottom of the wire stripping table 601, and a first in-place sensor 613 is fixedly installed at the top of the adjusting seat 612. Among them, when the end of the terminal wire passes above the first in-place sensor 613, the wire stripping assembly 6 can strip the terminal wire (the first in-place sensor 613 uses the method of infrared ranging, and the height of the solder wire is relatively high to achieve the purpose of distinguishing the arrival of the wire and the solder wire), and by adjusting the position of the adjusting seat 612, the purpose of adjusting the wire stripping length is achieved.

[0051] As Figure 8 In [reference], a second driving frame 7 is fixedly installed between the wire stripping assembly 6 and the soldering aid assembly 8 at the top of the soldering table 2. A plurality of pairs of driving rollers 701 for driving the solder wire and the peeled wire are rotatably installed in the second driving frame 7. The shafts of the two driving rollers 701 are fixedly installed with second gears 702 that mesh with each other. A driven bevel gear 703 is fixedly installed on the shaft of one of the driving rollers 701. A fifth driving rod 704 is rotatably installed on the second driving frame 7, and a plurality of driving bevel gears 705 that mesh with the driven bevel gear 703 are fixedly sleeved on the fifth driving rod 704. Among them, Figure 8 As described above, a motor for driving the fifth driving rod 704 to rotate is fixedly installed on the second driving frame 7. The motor drives the driving bevel gear 705 to rotate through the fifth driving rod 704. The rotation of the driving bevel gear 705 drives the driving roller 701 to rotate through the meshing action with the driven bevel gear 703, and then drives the adjacent driving rollers 701 to rotate in the opposite direction through the meshing action of the second gears 702 to convey the solder wire and the core of the peeled terminal wire (the overall diameters of the driving rollers 701 are different, and the larger diameter part can play a supporting role due to the soft solder wire). And the purpose of setting the second driving frame 7 to drive the conveyance of the solder wire and the core of the peeled terminal wire is to form a conveyance speed difference with the first driving frame, solving the problem that the solder wire and the core of the peeled terminal wire are relatively soft and are prone to deviation in the conveyance direction when the conveyance length is relatively long.

[0052] As Figure 9 — Figure 11In the figure, the soldering assembly 8 includes a soldering seat 801 and a wire hub 802. The soldering seat 801 is fixedly installed on the top of the soldering table 2. The wire hub 802 is fixedly inserted into the soldering table 2 and is slidably connected with the soldering seat 801. The soldering seat 801 and the wire hub 802 are both provided with holes for the tin wire and the peeled wire to pass through. One end of the soldering seat 801 is provided with a wire tube 803 above the hole. A plurality of second in-position sensors 804 are fixedly installed in the soldering seat 801. The top of the soldering seat 801 The top of the soldering base 801 is fixed with a mounting base 807 above the rosin placement port 805, and a pressure rod 808 is movably inserted on the mounting base 807. A pressure head 809 is fixedly installed at the bottom of the pressure rod 808. The pressure head 809 is movably inserted into the rosin placement port 805, and a pressure spring 810 is fixedly connected between the top of the pressure head 809 and the mounting base 807. In the process, the pressure rod 808 is used to pull the pressure head 809, and the rosin block is placed in the rosin placement port 805. The rosin is tightly pressed by the pressure spring 810. At the same time, the rosin is softened and melted under the heating action of the electric heating wire 806. The tin wire and the wire are continued to be transported under the driving action of the second driving frame 7. The tin wire changes direction through the wire tube 803 and finally merges with the peeled wire core at the hole opening of the soldering base 801 to complete the clamping (the peeled wire core is clamped in the groove of the tin wire). At the same time, it continues to be transported in the hole. The softened and melted rosin liquid flows into the hole of the tin wire during the transportation process, and finally the whole body extends out from one end of the wire hub 802 and is pressed down by the pressure welding head 1. (After the wire is extended, it is detected by the second in-position sensor 804, triggering the wire cutting component 5 to cut the wire, and at the same time continuing to drive the terminal wire transportation, realizing the purpose of automatic wire feeding and continuous processing). The main function of the wire hub 802 is to concentrate the wires and realize the spacing to adapt to the spacing of the metal contacts on the display circuit board.

[0053] For the specific working principle, place the end of the solder wire between the driving wheel 403 and the hole-pressing wheel 404, and place the end of the insulated terminal wire between the two driving wheels 403. When the second driving rod 401 and the third driving rod 402 rotate, they can drive the conveyance of the solder wire and the insulated wire. During the conveyance of the solder wire, the hole-pressing wheel 404 rotates, and the teeth on the hole-pressing wheel 404 can press holes at intervals on the top of the solder wire. The solder wire and the terminal wire enter the wire stripping table 601 through the guiding plate, and through the holes on the guiding plate. Since there are bumps in the holes, the bottom of the solder wire will be pressed out with card slots. When the end of the terminal wire passes the first in-place sensor 613 of the wire stripping assembly 6, it triggers the second electric push rod 610 to extend and push the toothed plate 611 to slide horizontally in the wire stripping table 601. The toothed plate 611 drives the driving disc 607 to rotate through the meshing action with the first gear 609. The rotation of the driving disc 607 drives the two wire stripping seats 604 to approach each other (under the limiting action of sliding on the wire stripping table 601) through the second connecting rod 608, and the outer skin of the terminal wire is clamped and cut off by the wire stripping pliers 605. After the outer skin is clamped and cut off, the second electric push rod 610 extends and pushes the wire stripping table 601 to slide horizontally on the second slide rail 602 (the second electric push rod 610 rotates while extending), so as to pull out the outer skin of the terminal wire from the wire core, achieving the purpose of automatically stripping the terminal wire;

[0054] After wire stripping, the wire core of the de-skinned terminal wire and the solder wire enter the second driving frame 7. The fifth driving rod 704 rotates to drive the driving bevel gear 705 to rotate. The rotation of the driving bevel gear 705 drives the driving roller 701 to rotate through the meshing action with the driven bevel gear 703, and then drives the adjacent driving rollers 701 to rotate in the opposite direction through the meshing action of the second gears 702 to convey the solder wire and the wire core of the de-skinned terminal wire (the overall diameters of the driving rollers 701 are different, and the larger-diameter part can play a supporting role due to the softness of the solder wire). The purpose of setting the second driving frame 7 to drive the conveyance of the solder wire and the wire core of the de-skinned terminal wire is to form a conveyance speed difference with the first driving frame, solving the problem that the solder wire and the wire core of the de-skinned terminal wire are soft and prone to deviation in the conveyance direction when the conveyance length is long. The wire core of the de-skinned terminal wire and the solder wire are conveyed into the soldering seat 801 through the second driving frame 7. The solder wire changes its direction through the wire tube 803 and finally converges with the wire core of the de-skinned wire at the pore opening of the soldering seat 801 and completes the clamping (the wire core of the de-skinned wire is clamped in the groove of the solder wire), and continues to be conveyed in the pore. During the conveyance process, the rosin is tightly pressed by the action of the pressing spring 810, and at the same time, the rosin becomes soft and melts under the heating action of the heating wire 806. The softened and melted rosin liquid flows into the pores of the solder wire, and finally the whole extends from one end of the wire gathering seat 802, and is pressed and welded by pressing down the welding head 1. The main function of the wire gathering seat 802 is to concentrate the wire materials and shorten the spacing to adapt to the spacing of the metal contacts on the display circuit board;

[0055] After the wire extends, it is detected by the second in-place sensor 804, triggering the wire cutting assembly 5. Through the sliding action of the first drive rod 101 and the upper limit slot of the T-shaped drive frame 9, the first drive rod 101 moves downward to drive the T-shaped drive frame 9 to rotate (rotate towards the pressure welding head 1). The rotation of the T-shaped drive frame 9 can drive the wire cutting assembly 5 to rise. The pressure welding head 1 in the wire cutting assembly 5 presses downward for welding, driving the fourth drive rod 503 to move upward, and driving two first connecting rods 505 to rotate (the included angle becomes smaller). The first connecting rods 505 drive the two tool holders 502 to approach each other to clamp and cut the insulated wire. At the same time, the height of the wire stripping rod 901 decreases to press and separate the wire from the soldering aid assembly 8 after wire cutting is completed. At the same time, the terminal wire conveying is continuously driven to achieve the purpose of automatic wire conveying and continuous processing.

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
