[0019] In the following, through specific embodiments and with reference to the drawings, the structure and other aspects of the packaging device of the present invention will be further described in detail.

[0020] As Figure 1 and Figure 2As shown, the encapsulation device of the present utility model is used to assemble or sleeve a hollow tube body 94 onto a thermistor 92 to encapsulate the thermistor 92. The thermistor 92 is welded between two parallel wires 90. The parallel wires 90 welded together and the thermistor 92 are placed equidistantly on a flat plate 91. The flat plate 91 is fed into the encapsulation device of the present utility model for encapsulation operation.

[0021] According to an embodiment, the encapsulation device of the present utility model includes a feeding device 51, a sleeving device 52, a transfer device 53, and a wire clamping device 54. The feeding device 51 is used to continuously and automatically supply the tube body 94. To improve efficiency, the supply device 51 can supply multiple tube bodies 94 at a time. The sleeving device 52 is used to sleeve the tube body 94 onto the thermistor 92. The transfer device 53 is used to transfer the tube body 94 from the feeding device 51 to the sleeving device 52. The wire clamping device 54 is used to clamp the parallel wires 90 welded to the thermistor 92. After the wire clamping device 54 clamps the parallel wires 90, the sleeving device 52 moves towards the thermistor 92 until the tube body 94 is sleeved onto the thermistor 92, that is, the thermistor 92 extends into the interior of the tube body 94.

[0022] As Figure 3 shown, in an embodiment, the feeding device 51 includes a horizontal plate 511, a rotating brush 512, and a baffle 513. A groove 511a is provided on the horizontal plate 511, and the tube body 94 is accommodated in the groove 511a. In a specific embodiment, there are multiple grooves 511a, which can simultaneously accommodate multiple tube bodies 94 side by side. The baffle 513 is provided at the end of the groove 511a. The rotating brush 512 rotates driven by a motor 515. When the rotating brush 512 rotates, it can contact the stacked tube bodies 94 to prevent the tube bodies 94 from stacking. A vibration block 514 is provided below the horizontal plate 511, and the tube bodies on the groove 511a of the horizontal plate 511 are conveyed towards the baffle 513 by vibration until they are blocked from moving forward by the baffle 513. In this way, the tube bodies 94 in the front of multiple grooves 511a are aligned along the side surface of the baffle 513.

[0023] As Figure 4As shown, in one embodiment, the transfer device 53 includes a suction nozzle 531 (first suction nozzle), a bracket 532 (first bracket), and a driving motor 533 (first driving part). The nozzle 531 can adsorb the tube body 94 on the feeding device 51 to the transfer device 53. The suction nozzle 531 is mounted on the bracket 532. The bracket 532 is connected to the driving motor 533 through a rotating arm 534, thereby driving the bracket 532 to move. The bracket 532 can rotate relative to the rotating arm 534 about a rotating shaft 532a. Both the driving motor 533 and the bracket 532 are mounted on a frame 535. A semi-circular track 535a is provided on the frame 535, and at least a part of the rotating shaft 532a extends into the track 535a. A transverse slide rail 535b is provided on the frame 535, and a slider 536 can move horizontally along the transverse slide rail 535b. The slider 536 is also slidably connected to the bracket 532. When the transfer device 53 is working, the driving motor 533 drives the rotating arm 534 to rotate, and the rotating arm 535 then drives the bracket 532 to move back and forth in the first direction X or up and down in the second direction Z. The bracket 532 always maintains a vertical posture under the guidance of the slider 536.

[0024] As Figure 5 shown, in one embodiment, the wire clamping part 54 includes a clamping part 541 and a slide rod 542. The clamping part 541 further includes an upper clamp 541a and a lower clamp 541b. The lower clamp 541b is connected to a screw rod 543, and the screw rod 543 is further connected to a driving motor (not shown). When the screw rod 543 rotates, it can move axially at the same time. Both the upper clamp 541a and the lower clamp 541b are arranged on the slide rod 542. The upper clamp 541a is fixed on the slide rod 542, and the lower clamp 541b can slide up and down along the slide rod 542. The driving motor drives the screw rod 543 to rotate, and the screw rod 543 then drives the lower clamp 541b to slide up and down along the slide rod 542, thereby realizing the closing or opening of the upper clamp 541a and the lower clamp 541b.

[0025] As Figure 6 shown, in one embodiment, the sleeve device 52 includes a suction nozzle 521 (second suction nozzle), a bracket 522 (second bracket), and a driving cylinder 523 (second driving part). The suction nozzle 521 is used to adsorb the tube body 94. The suction nozzle 521 is arranged on the bracket 522. The number of the suction nozzles 521 is the same as that of the suction nozzles 511. The driving cylinder 523 can drive the bracket 522 to move in the third direction Y to approach or move away from the thermistor on the flat plate 91. Specifically, the bracket 522 and the driving cylinder 523 are arranged on a base 525. The base 525 is provided with a slide rail 525a. Correspondingly, the bracket 522 is provided with a matching slide rail 522a, and the bracket 522 can move in the third direction Y relative to the base 525 along the slide rail.

[0026] When the packaging device of the present utility model is working, the feeding device 51 arranges the tube bodies 94 as a whole, and at the same time transports the flat plate 91 with the parallel wires 90 and the thermistor 92 placed thereon to an appropriate position of the packaging device of the present utility model. The suction nozzle 531 of the transfer device 53 moves in the first direction X towards the feeding device 51 until it reaches above the tube body 94 in contact with the baffle 513. The suction nozzle 531 moves downward in the second direction Z towards the position of the tube body 94. The suction nozzle 531 adsorbs a row of tube bodies 94 in contact with the baffle 513. The suction nozzle 531 moves upward in the second direction Z towards a position away from the tube body 94, and then moves in the first direction X towards a position close to the sleeve device 52 until it reaches above the suction nozzle 521. The suction nozzle 531 moves downward in the second direction Z towards the suction nozzle 521 until the tube body 94 contacts the suction nozzle 521. The suction nozzle 521 adsorbs the tube body 94, and at the same time the suction nozzle 531 disengages from the tube body 94. The transfer device 53 recycles the above movement path to transfer the second row of tube bodies 94.

[0027] After the suction nozzle 521 of the sleeve device 52 adsorbs the tube body 94, the clamping portion 541 of the wire clamping device 54 clamps the parallel wires 90, and the driving cylinder 523 of the sleeve device 52 drives the bracket 522 to move in the third direction Y towards the thermistor 92 until the tube body 94 is sleeved on the thermistor 92, and the suction nozzle 521 no longer adsorbs the tube body 94. The wire clamping device 54 is opened, and the suction nozzle 521 moves in the third direction Y away from the thermistor 92. After the flat plate 91 is advanced a certain distance in the first direction X, the wire clamping device 54 and the sleeve device 52 recycle the above actions to continuously sleeve the tube body 94 on the thermistor 92. The packaging device of the present utility model can sleeve the tube body on the thermistor in an automated manner, thereby realizing the packaging of the thermistor, and has high production efficiency.

[0028] The above embodiments are only used to illustrate the concept and scope of the present utility model, and are not used to limit the protection scope of the present utility model. Modifications, equivalent replacements, and other improvements that are obvious to those skilled in the art to the above embodiments are also within the concept of the present utility model.
