[0018] In order to more clearly understand the above-mentioned purpose, 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 the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] 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 of the following disclosure.

[0020] Embodiment, according to Figure 1 — Figure 11 ,like Figure 1 In the embodiment of the present invention, a welding device for manufacturing a display screen includes a welding head 1, a welding table 2, a wire rack 3 for placing a wire coil and a tin wire coil, a first driving rack 4, a second driving rack 7 and a T-shaped driving rack 9. The welding head 1 is arranged just above one end of the welding table 2, and the first driving rack 4 is fixedly installed on the top of the welding table 2 and is located between the wire rack 3 and the welding head 1. The welding head 1 also includes: A wire cutting assembly 5 for cutting wires is provided between the first driving frame 4 and the pressure welding head 1; A wire stripping assembly 6 for stripping the wires and arranged between the wire cutting assembly 5 and the welding head 1; A fluxing assembly 8 is provided between the wire stripping assembly 6 and the pressure welding head 1 .

[0021] like Figure 1 In the figure, a limiting groove is provided on the T-shaped driving frame 9, and the first driving rod 101 is fixedly installed at both ends of the pressure welding head 1, and the first driving rod 101 and the fourth driving rod 503 are both slidably installed in the limiting groove in the T-shaped driving frame 9, and a wire stripping rod 901 is integrally formed at the bottom of the T-shaped driving frame 9, and the wire stripping rod 901 is placed between the tin wire and the peeled wire, wherein the pressure welding head 1 is pressed down for pressure welding, and through the sliding action of the first driving rod 101 and the upper limiting groove of the T-shaped driving frame 9, the first driving rod 101 moves downward to drive the T-shaped driving frame 9 to rotate (rotate toward the side of the pressure welding head 1), and 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 is reduced to press the wire down and disengage it from the soldering assembly 8 after the wire cutting is completed.

[0022] like Figure 2In it, the wire rack 3 is fixedly installed on one side of the top of the welding table 2 away 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 and tin wire reels are sleeved on the two placing rods 301 respectively. A positioning cap 303 is installed on one end of the placing rod 301 by threading. 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 hole pressing 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 removed to replace the tin coil and the wire coil. After the replacement is completed, 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 in, 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. Place the tin wire between the driving wheel 403 and the hole pressing wheel 404, and place the insulated terminal wire 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 insulated wire can be driven to be conveyed. During the conveying process of the tin 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 tin wire for subsequent addition of flux.

[0023] As Figure 3 shown in, 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 cut off the insulated wire, so as to achieve the purpose of automatic wire cutting.

[0024] As Figure 4 shown in, 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 protrusions for grooving the tin wire. Among them, during the conveying process of the tin wire, through the holes on the guide plate, due to the protrusions in the holes, grooves will be pressed out at the bottom of the tin wire, so that the peeled wire core can be stuck into the grooves.

[0025] As Figure 5 and Figure 7In 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 soldering 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 rail 602 and the wire stripping table 601. Two chutes are provided 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 seat 604. A convex rod 606 is provided at the bottom of the wire stripping seat 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 disk 607 and the convex rod 606. A first gear 609 is fixedly installed on the shaft of the driving disk 607. A toothed plate 611 meshing with a plurality of first gears 609 is slidably installed in the wire stripping table 601. A second electric push rod 610 for driving the toothed plate 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 toothed plate 611 to translate and slide in the wire stripping table 601. The toothed plate 611 drives the driving disk 607 to rotate through the meshing action with the first gear 609. The driving disk 607 drives 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. The outer skin of the terminal wire is clamped and cut off by the wire stripping pliers 605. After the outer skin is cut off, the second electric push rod 610 extends and pushes the wire stripping table 601 to translate and slide 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.

[0026] As Figure 5 and Figure 6 In it, a plurality of adjusting seats 612 are fixedly installed at the bottom of the wire stripping table 601. A first in-place sensor 613 is fixedly installed on 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 be triggered to 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 stripping length is achieved.

[0027] As Figure 8 In it, a second driving frame 7 is fixedly installed between the wire stripping assembly 6 and the soldering aid assembly 8 on the top of the soldering table 2. A plurality of pairs of driving rollers 701 for driving the solder wire and the wire with the outer skin removed are rotatably installed in the second driving frame 7. Second gears 702 meshing with each other are fixedly installed on the shafts of the two driving rollers 701. 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. A plurality of driving bevel gears 705 meshing with the driven bevel gear 703 are fixedly sleeved on the fifth driving rod 704. Among them, by Figure 8As described, a motor for driving the fifth driving rod 704 to rotate is fixedly installed on the second driving frame 7, and the motor drives the active bevel gear 705 to rotate through the fifth driving rod 704. The active bevel gear 705 rotates and drives the driving roller 701 to rotate through the meshing action with the driven bevel gear 703, and then the mutual meshing action of the second gear 702 is used to drive the adjacent driving rollers 701 to rotate in the opposite direction to convey the tin wire and the peeled terminal conductor core (the overall diameter of the driving roller 701 is different, and the larger diameter part can play a supporting role because the tin wire is softer). The purpose of setting the second driving frame 7 to drive the conveyance of the tin wire and the peeled terminal conductor core is to form a conveying speed difference with the first driving frame, thereby solving the problem that the driving tin wire and the peeled terminal conductor core are soft and the conveying direction is easily offset when the conveying length is long.

[0028] like Figure 9 — Figure 11 In the embodiment, the soldering assembly 8 includes a soldering seat 801 and a wire collection seat 802. The soldering seat 801 is fixedly installed on the top of the soldering table 2. The wire collection seat 802 is fixedly inserted on the soldering table 2 and slidably engaged with the soldering seat 801. The soldering seat 801 and the wire collection seat 802 are both provided with holes for the solder wire and the peeled wire to pass through. One end of the soldering seat 801 is located above the hole and a wire tube 803 is provided. 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 located above the rosin placement port 805 and is fixedly installed with a mounting seat 807. A pressure rod 808 is movably inserted on the mounting seat 807. A pressure head 809 is fixedly installed at the bottom of the pressure rod 808. The pressure head 809 is movably inserted in the rosin placement port 805. A pressure spring 810 is fixedly connected between the top of the pressure head 809 and the mounting seat 807. In the process, the pressing rod 808 is used to pull the pressing head 809, and the rosin in blocks is placed in the rosin placement port 805. The rosin is tightly pressed by the pressure spring 810, and the rosin is softened and melted under the heating action of the electric heating wire 806. The tin wire and the wire are continuously conveyed 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 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 conveyed in the hole. The softened and melted rosin liquid flows into the hole of the tin wire during the conveying process, and finally the whole body extends out from one end of the wire hub 802, and is pressed and welded by the pressure welding head 1 (after the wire is extended, it is detected by the second in-position sensor 804, which triggers the wire cutting component 5 to cut the wire, and at the same time continues to drive the terminal wire to be conveyed, so as to achieve the purpose of automatic wire conveying and continuous processing). The function of the wire hub 802 is mainly to concentrate the wires, and the spacing is realized to adapt to the spacing of the metal contacts on the display circuit board.

[0029] 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 guide plate, and through the holes on the guide 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 extends and rotates itself) to pull out the outer skin of the terminal wire from the wire core, achieving the purpose of automatically stripping the terminal wire; After wire stripping, the wire core of the de-skinned terminal wire and the solder wire enter the second driving frame 7. The rotation of the fifth driving rod 704 drives the rotation of the driving bevel gear 705. The rotation of the driving bevel gear 705 drives the rotation of the driving roller 701 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 orifice 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 orifice. During the conveyance process, the rosin is tightly pressed by the action of the pressure 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 holes of the solder wire, and finally the whole extends from one end of the wire collecting seat 802, and is pressed and welded by pressing down the welding head 1. The main function of the wire collecting seat 802 is to concentrate the wire materials and shorten the distance to adapt to the distance between the metal contacts on the display circuit board; After the wire extends out, it is detected by the second in-place sensor 804, triggering the wire cutting assembly 5. Through the sliding action of the first driving rod 101 in the upper limit slot of 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). The rotation of the T-shaped driving 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 driving 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. Meanwhile, 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.
