[0144] Working principle:

[0145] Before using the automatic welding device for cable plugs, the operator needs to set the plug size required for welding and the related parameters of the plug welding point position interval in the control system.

[0146] It is emphasized again that the present application does not protect the control system and the driving control method. The present application can realize the movement control of the moving clamping mechanism 2, the moving welding mechanism 3, the welding wire conveying mechanism 4, the solder storage mechanism 5, the plug fixing mechanism 6 and the clamping plate conveying mechanism 7 by means of the existing drivers in the market.

[0147] The plug K of the cable to be welded is placed and fixed in the plug clamping seat 6D, and then the position of the plug K is adjusted through the front and rear adjusting sliding table 6B and the left and right adjusting sliding table 6C; the plug K is an aviation plug, which is in a cylindrical shape, one end of which is a pin or a socket, and the other end is a terminal post K1 connected with a pin spring or a socket spring, the plug K is provided with a plurality of rows of terminal posts K1, each row of terminal posts K1 is arranged in order from top to bottom, and the left and right spacing of each row of terminal posts K1 is the same; when the plug K is fixed in the plug clamping seat 6D, the terminal post K1 is outward.

[0148] As shown in Figure 24 .

[0149] The cable L to be welded is placed and clamped in the 7C2a wire clamping tooth groove on the cable lower clamping plate 7C2 of the cable clamping plate component 7C in order, and then the cable upper clamping plate 7C1 is placed on the cable lower clamping plate 7C2 to press and fix the cable L clamped in the 7C2a wire clamping tooth groove;

[0150] As shown in Figure 25 .

[0151] The number of cable clamp plate components 7C clamping cable L is equal to the number of rows of terminal pins K1 on plug K. The spacing of each 7C2a clamping tooth slot for placing cable L is the same as the spacing of terminal pins K1 on plug K corresponding to each row of wires to be welded. At this time, the number, type and spacing of cable L clamped by each cable clamp plate component 7C correspond to the terminal pins K1 on plug K that are ready to be welded to the wires, so as to wait for subsequent soldering connection by solder wire.

[0152] Each cable clamp plate component 7C clamping cable L is installed on the hook end 7BA of the corresponding transmission clamping component 7B through the 7C3a bottom block clamping groove. Each group of transmission clamping components 7B and cable clamp plate components 7C are arranged in the order of the corresponding relationship between the cables L in the clamped cable clamp plate components 7C and the rows of terminal pins K1 on plug K, with the cable clamp plate components 7C and transmission clamping components 7B corresponding to the lowermost row of terminal pins K1 as the first, and the other groups of cable clamp plate components 7C and transmission clamping components 7B arranged in the order of the rows of terminal pins K1 from bottom to top, and then fixedly installed on the 7A4a transmission buckle of the clamp transmission component 7A through the 7B2a transmission bottom plate buckle of the bottom of each transmission clamping component 7B, with the clamping swing lever 7B3a of each transmission clamping component 7B facing one side of the transmission cam 7A2 during installation.

[0153] The solder wire is extracted from the solder storage mechanism 5, first threaded into the roller clamping conveying structure of the solder wire conveying mechanism 4, and then threaded into the solder guide pipe 3B4. The solder wire in the solder storage mechanism 5 can be conveyed to the solder guide pipe 3B4 by the solder wire conveying mechanism 4, and by adjusting the welding clamping frame 3B3, the solder wire extending from the solder guide pipe 3B4 is located at the front of the welding gun 3B5, so as to heat and melt the solder wire by the welding gun 3B5, and realize the soldering connection of each cable L and plug K corresponding point.

[0154] As shown in Figure 26 .

[0155] The clamping plate holding and moving assembly 2B in the mobile clamping mechanism 2 is driven by the clamping slide assembly 2A to the position closest to the plug fixing mechanism 6, and the holding and moving mounting hole 2B1a of the holding and moving mounting block 2B1 is moved and sleeved on the clamping plate plug-in block 7C2c by the clamping slide assembly 2A, that is, the clamping plate plug-in block 7C2c is inserted into the holding and moving mounting hole 2B1a, and the two are clearance fit; at this time, the clamping plate fixing hole 7C2b on the clamping plate plug-in block 7C2c is just below the holding and moving telescopic electromagnet 2B2, and then the holding and moving telescopic electromagnet 2B2 is energized, so that the telescopic rod 2B2a of the holding and moving telescopic electromagnet 2B2 is inserted into the clamping plate fixing hole 7C2b; the lower end of the telescopic rod 2B2a has a certain taper and a tapered surface, the clamping plate fixing hole 7C2b is also a tapered hole with a wide upper part and a narrow lower part, and the tapers of the two are the same, so when the lower part of the telescopic rod 2B2a is inserted into the clamping plate fixing hole 7C2b, the telescopic rod 2B2a can press and fix the clamping plate plug-in block 7C2c in the holding and moving mounting hole 2B1a through the tapered surface structure;

[0156] As shown in Figure 27 .

[0157] The transmission motor 7A5 is started, the transmission motor 7A5 drives the transmission synchronous belt 7A4 to run forward, and then forms a belt transmission; each transmission clamping part 7B is clamped and fixed on the transmission buckle 7A4a of the transmission synchronous belt 7A4 through the transmission bottom plate 7B2a; each transmission clamping part 7B is clamped and fixed with a cable clamping plate part 7C, and each cable clamping plate part 7C is clamped and fixed with a cable L to be welded;

[0158] The forward movement of the transmission synchronous belt 7A4 will drive the transmission clamping part 7B to move forward, and the mobile clamping mechanism 2 which is currently clamped and fixed with the cable clamping plate part 7C will move forward with the transmission synchronous belt 7A4 under the action of the clamping slide assembly 2A.

[0159] As shown in Figure 28 .

[0160] The transmission clamping component 7B and the cable clamping plate component 7C run forward with the transmission synchronous belt 7A4, and when the clamping swing lever 7B3a of the transmission clamping component 7B touches the transmission cam 7A2, the transmission cam 7A2 is fixed on the transmission chassis 7A1, so that the rotation of the dial shaft 7B3 is driven to rotate as the transmission synchronous belt 7A4 runs forward; the clamping cam 7B3c rotates with the dial shaft 7B3, and the cam transmission is formed between the clamping cam 7B3c and the clamping cam block 7B7, and the rotation of the clamping cam 7B3c drives the clamping cam block 7B7 to run downward along the transmission clamping cover 7B1; the center of gravity of the front end clamping jaw 7B5 is located above the front clamping jaw rotating hole 7B5b and close to the clamping jaw hook end 7BA, and the center of gravity of the rear end clamping jaw 7B4 is located above the rear clamping jaw rotating hole 7B4b and close to the clamping jaw hook end 7BA; the downward running of the clamping cam block 7B7 drives the front end clamping jaw 7B5 and the rear end clamping jaw 7B4 to roll upward along the two sides of the clamping cam block 7B7 under the action of their own gravity, respectively, and the front end clamping jaw 7B5 and the rear end clamping jaw 7B4 rotate outward around the clamping jaw rotating shaft 7B6, respectively, so that the clamping jaw hook end 7BA is separated from the 7C3a bottom block clamping groove, that is, the transmission clamping component 7B and the cable clamping plate component 7C are separated.

[0161] As shown in Figure 29 .

[0162] The separated cable clamping plate component 7C is clamped by the clamping plate holding and conveying assembly 2B and moved to the vicinity of the plug fixing mechanism 6 under the driving of the clamping sliding table assembly 2A; the clamping sliding table assembly 2A aligns the cable clamping plate component 7C with the plug K fixed in the plug clamping seat 6D, and the cable L welded in the cable clamping plate component 7C is aligned with the corresponding terminal post K1 on the plug K; the clamping sliding table assembly 2A runs to the plug K, driving the cable L to be close to the corresponding terminal post K1;

[0163] As shown in Figure 30 .

[0164] The operator can adjust the welding adjustment frame 3B1, adjust the welding gun 3B5 to the appropriate angle, so as to be able to align the plug K and the cable L to be welded; start the moving welding mechanism 3, and the welding slide assembly 3A drives the welding holding and conveying assembly 3B to approach the welding position of the plug K and the cable L; the welding wire conveying mechanism 4 starts to convey the welding wire in the solder storage mechanism 5 to the front end of the solder guide pipe 3B4; the welding gun 3B5 is driven by the welding lead screw slide 3B2 to extend forward, and travels to the intersection of the next pair of cables L and the terminal K1 to be welded, melts the welding wire conveyed by the solder guide pipe 3B4 by the welding gun 3B5, and the molten solder flows to the intersection of the pair of cables L and the terminal K1, and then the welding gun 3B5 is driven by the welding lead screw slide 3B2 to retract backward, and in this process, the solder rapidly solidifies, realizing the welding of the current pair of cables L and the terminal K1; repeat the above process to complete the welding of the cables L in the current cable clamp plate component 7C and the corresponding terminals K1; then the operator removes the upper cable clamp plate 7C1 on the cable clamp plate component 7C, releases the pressing and fixing of the current cables L, takes out each cable L from the wire clamping tooth groove 7C2a, and installs the upper cable clamp plate 7C1 back on the lower cable clamp plate 7C2;

[0165] The clamping slide assembly 2A moves the current cable clamp plate part 7C back to the corresponding transmission clamping part 7B through the clamping and holding assembly 2B, and places the cable clamp bottom block 7C3 in the clamping and fixing area of the rear end clamping jaw 7B4 and the front end clamping jaw 7B5; the transmission motor 7A5 starts to drive the transmission synchronous belt 7A4 to run forward, and the clamping slide assembly 2A also drives the cable clamp plate part 7C to run forward at the same speed and direction; in this process, the clamping swing rod 7B3a runs forward along the surface shape of the transmission cam 7A2 under the driving of the 7A4 transmission synchronous belt, and the rotating shaft 7B3 drives the rear end clamping jaw 7B4 and the front end clamping jaw 7B5 to gradually open and then gradually close; in the closing process, the clamping jaw hook end 7BA of the rear end clamping jaw 7B4 and the front end clamping jaw 7B5 gradually extends into the 7C3a bottom block clamping groove of the cable clamp bottom block 7C3, so as to realize the fixing of the rear end clamping jaw 7B4 and the front end clamping jaw 7B5 to the cable clamp bottom block 7C3, and then realize the clamping and fixing of the transmission clamping part 7B to the cable clamp plate part 7C; then the telescopic electromagnet 2B2 retracts the telescopic rod 2B2a from the 7C2b clamping and fixing hole, releases the fixing of the 7C2c clamping and fixing block to the 7C2c clamping and fixing block, uses the movement of the clamping slide assembly 2A to move the clamping and holding assembly 2B from the side of the cable clamp plate part 7C, and approaches the next set of transmission clamping parts 7B and the cable clamp plate part 7C in sequence, and repeats the above process to complete the welding of the clamped cable L in the next cable clamp plate part 7C to the corresponding row of terminal posts K1, until the welding work of the required terminal posts K1 and cables L on the plug K is completed, and the operator takes out the plug K from the plug clamping seat 6D, and the required wire welding work of the plug K is completed.

[0166] If welding is required, a new plug K is placed in the plug clamping seat 6D; and the above steps are repeated to realize the welding of the cable L on the newly placed plug K.
