[0021] In the following, through specific embodiments and with reference to the drawings, the structure and other aspects of the welding device of the present invention will be further described in detail.
[0022] As Figure 1 andFigure 2 As shown, the welding device of the present utility model is used to weld the thermistor 92 to the end of the wire 90. The wires 90 are placed on the flat plate 91 at equal intervals. The end of the wire 90 is infiltrated with a metal paste before contacting the thermistor. The metal paste is, for example, silver paste or gold paste. In a preferred embodiment, transverse grooves 911 are provided on the flat plate 91 at equal intervals, and the wires 90 are placed in the transverse grooves 911. The welding device of the present utility model includes a feeding device 31, a wire lifting device 32, and a wire transferring device 33. The feeding device 31 is used to output the scattered thermistors 92 in sequence. The wire lifting device 32 is used to lift the wire 90 from the flat plate 91 to facilitate the wire transferring device 33 to grab the wire 90.
[0023] In one embodiment, the feeding device 31 includes a feeding tray 311 and a guiding track 312. The feeding tray 311 is used to accommodate the scattered thermistors 92. The feeding tray 311 is arranged such that when the feeding tray 311 rotates, the thermistors 92 are conveyed one by one to the outlet of the feeding tray 311. The outlet of the feeding tray 311 is connected to the guiding track 312. The thermistors 92 enter the guiding track 312 in sequence through the outlet and move forward along the guiding track 312, as Figure 3 shown. In a specific embodiment, a vibrator 313 is provided below the guiding track 312, and the thermistors 92 move forward along the guiding track 213 under the action of the vibrator 313.
[0024] As Figure 4 shown, in one embodiment, the wire lifting device 32 includes a driving cam 321 (the first driving cam) and a motor 322. The driving cam 321 can rotate under the drive of the motor 322. The driving cam 321 and the motor 322 are installed on the base 323. The wire lifting device 32 further includes a claw 324 and a bracket 325. The claw 324 is installed at the upper end of the bracket 325 and moves together with the bracket 325. In this embodiment, there are two claws 324. The distance between the two claws 324 is greater than the width of the flat plate 91 and less than the length of the wire 90, so that the wire lifting device 32 can lift the wire from below the wire 90 without touching the flat plate 91. The lower end of the bracket 325 contacts the circumferential surface of the driving cam 325. When the driving cam 325 rotates, it can push the bracket 325 to reciprocate in the third direction Z. Slide rails are provided on both the bracket 325 and the base 323, and the bracket 325 can move in the third direction Z along the slide rails. The wire lifting device 32 further includes a spring 326. One end of the spring 326 is connected to the bracket 325, and the other end is connected to the base 323. The spring 326 can apply a restoring force to the bracket 325 that is opposite to the acting force of the driving cam 321, thereby realizing the reciprocating movement of the claw 324 in the third direction Z.
[0025] As Figures 5 to 7As shown, in one embodiment, the wire transfer device 33 includes a wire clamping portion 331, a bracket 332, a motor 333, and a driving cam 334 (second driving cam). The motor 333 and the driving cam 334 are mounted on the bracket 332. The wire clamping portion 331 can be opened or closed to clamp the wire 90. The motor 333 drives the driving cam 334 to rotate. The wire clamping portion 331 contacts the circumferential surface of the driving cam 334. When the driving cam 334 rotates, it drives the wire clamping portion 331 to reciprocate in the first direction X. The relative movement between the wire clamping portion 331 and the bracket 332 is achieved through the slide rails provided thereon. One end of the spring 335 is connected to the wire clamping portion 331, and the other end is connected to the bracket 332. The spring 335 applies a pulling force to the wire clamping portion 321, and the direction of the pulling force is opposite to the direction of the thrust applied by the driving cam 334. In this way, the reciprocating movement of the wire clamping portion 331 in the first direction X can be achieved.
[0026] The wire transfer device 33 further includes a driving cam 336 (third driving cam) and a motor 337. The driving cam 336 and the motor 337 are mounted on the bracket 338. The bracket 338 includes a horizontal portion 338a and a vertical portion 338b. The bracket 332 can reciprocate in the third direction Z relative to the vertical portion 338b of the bracket 338. The relative movement between the bracket 332 and the vertical portion 338b is achieved through the slide rails provided thereon. The circumferential surface of the driving cam 336 contacts the upper end of the bracket 332. When the driving protrusion 336 rotates driven by the motor 337, it drives the bracket 332 to reciprocate in the third direction Z, thereby achieving the reciprocating movement of the wire clamping portion 331 in the third direction. One end of the spring 339 is connected to the bracket 332, and the other end is connected to the bracket 338. The pulling force applied by the spring 339 is opposite to the direction of the thrust applied by the driving cam 336. In this way, the reciprocating movement of the bracket 332 and the wire clamping portion 331 in the third direction Z can be achieved.
[0027] The wire transfer device 33 further includes a motor 340 and a lead screw (not shown). The lead screw is connected to the horizontal portion 338a of the bracket 338. When the motor 340 drives the lead screw to rotate, it can drive the bracket 338 to reciprocate in the second direction Y. The horizontal portion 338a is provided with slide rails, and the horizontal portion 338a can reciprocate in the second direction Y along the horizontal slide rails 341. When the motor 340 drives the lead screw to rotate clockwise or counterclockwise, it can drive the bracket 338 to reciprocate.
[0028] When the welding device of the present utility model works, first, wires 91 are placed equidistantly on the flat plate 91, and the flat plate 91 is conveyed to the appropriate position of the welding device of the present utility model. The feeding device 31 conveys the scattered thermistors 92 to the end of the guiding track 312 in sequence. The wire lifting device 32 is located below the flat plate 91 and the wire 90. The wire lifting device 32 moves upward along the third direction Z until the claw 324 lifts the wire 90, separating the wire 90 from the flat plate 91. The wire transfer device 33 moves in the third direction Z towards the wire direction and clamps the wire 90 on the claw 324. As Figure 8 shown, after clamping the wire 90, the wire transfer device 33 moves in the second direction Y to approach the thermistor 92, and makes the end of the wire 90 contact the upper surface of the thermistor 92. Since the end of the wire 90 is infiltrated with metal paste, after the end of the wire 90 contacts the upper surface of the thermistor 92, the thermistor 92 will be bonded to the end of the wire 90. The wire transfer device 33 returns to above the flat plate 91 along the second direction Y, and moves in the first direction X to above the wire adjacent to the clamped wire 90. The wire transfer device 33 moves towards the flat plate 91 in the third direction Z and places the clamped wire 90 on the flat plate 91. The wire 90 bonded with the thermistor 92 is superimposed on another adjacent wire 90 on the flat plate 91. The end of the other wire 90 is also infiltrated with metal paste, and the end of the other wire 90 is bonded to the lower surface of the thermistor 92. In this way, the thermistor 92 is clamped between two wires 90 and welded together by an automated method.
