[0040] like Figures 1 to 6 As shown, this utility model embodiment provides a desoldering device, including a mounting shell 100, two sliders 200, an annular wall 300, a heat-resistant panel 400, and two clamping plates 500.

[0041] The mounting shell 100 has a groove 110 at its upper end. Two sliders 200 are disposed opposite each other in the groove 110 and can move linearly toward or away from each other. A heat-resistant panel 400 covers the upper end of the mounting shell 100. The heat-resistant panel 400 is preferably a tempered glass panel. An annular wall 300 is disposed on the inner bottom wall of the groove 110 and located between the two sliders 200. The annular wall 300 forms a mounting cavity 310, which communicates with the interior of the mounting shell 100. A heating plate 320 is disposed in the mounting cavity 310. Specifically, the upper ends of the sliders 200 and the annular wall 300 are flush with the upper end of the shell.

[0042] Two clamping plates 500 are positioned opposite each other above the heat-resistant panel 400 and correspond to the two sliders 200 respectively. A connector 510 is provided on the clamping plate 500. A strip hole 410 is provided on the heat-resistant panel 400 along the movement direction of the slider 200 and corresponding to the connector 510. The connector 510 passes through the strip hole 410 and connects to the corresponding slider 200. The strip hole 410 has a guiding function, can limit the movement distance of the slider 200, and can also play a foolproof role, allowing for operation by the operator.

[0043] The recessed groove 110 reduces space occupancy, making the overall structure more compact and facilitating assembly and maintenance. During operation, the circuit board is clamped by adjusting the two clamping plates 500. The heating plate 320 then transfers heat to the heat-resistant panel 400, and further to the circuit board, melting the solder. Electronic components can then be removed from the circuit board using tools. The operation is simple and convenient, with high efficiency. Both clamping plates 500 can move independently, increasing operational flexibility and enhancing the user experience.

[0044] It should be noted that steps 520 are provided on the opposite surfaces of the two clamping plates 500. The upper ends of the two steps 520 are flush, and the lower end of the circuit board rests against the steps 520. The step 520 can prevent the circuit board from being placed unevenly due to the uneven height of the silver pins on the electronic components. In other words, the steps 520 on the two clamping plates 500 can keep the circuit board in a horizontal state, so that all parts of the circuit board can be heated evenly, which can improve the efficiency of disassembling or soldering electronic components.

[0045] In one embodiment, the slider 200 includes a connecting portion 210 and an arm portion 220. The connecting portion 210 is arranged along the length direction of the clamping plate 500 and its width is less than the width of the groove 110. The arm portions 220 are arranged at both ends of the connecting portion 210. Furthermore, the arm portions 220 extend toward the annular wall 300 and are inclined away from the connecting portion 210. A sliding surface 221 is provided on the side of the arm portion 220 away from the other arm portion 220. The sliding surface 221 is slidably connected to the inner sidewall of the groove 110. The arm portion 220 can improve the stability of the slider 200 structure, and the sliding surface 221 can further improve the stability of the slider 200 movement and prevent it from shaking.

[0046] In one embodiment, each clamping plate 500 is provided with two connectors 510, and the two connectors 510 correspond to the two arms 220 on the corresponding slider 200 respectively. The connectors 510 are fixedly connected to the corresponding arms 220 to ensure the stability of the clamping plate 500 installation. Specifically, the connectors 510 are preferably screws.

[0047] In one embodiment, the connecting portion 210 on each slider 200 is threadedly connected to a lead screw 600. The lead screw 600 is disposed in the groove 110 along the movement direction of the slider 200. Both ends of the lead screw 600 are provided with fixed seats that are rotatably connected to it. The fixed seats are fixed in the groove 110 so that the lead screw 600 can rotate around its axis to drive the corresponding slider 200 to move linearly away from or closer to another slider 200. The lead screw 600 can improve the adjustment accuracy and improve work efficiency. Furthermore, the end of the lead screw 600 away from the annular wall 300 extends outward through the mounting shell 100 and is exposed relative to the mounting shell 100. The exposed end of the lead screw 600 is provided with an operating element 700. The structure is simple and convenient for the operator to apply force. Specifically, the operating element 700 is preferably a knob.

[0048] In one embodiment, the mounting housing 100 is provided with a cooling fan 800 corresponding to the heating plate 320 inside, and an air inlet 120 corresponding to the cooling fan 800 is provided at the lower end of the mounting housing 100. An air outlet 130 is provided on the side wall of the mounting housing 100. The cooling fan 800 is provided to dissipate heat from the heating plate 320 to facilitate subsequent operations.

[0049] In one embodiment, the bottom of the mounting housing 100 is provided with four anti-slip pads 140 in a rectangular shape. The anti-slip pads 140 can provide stable support, prevent the device from shifting during operation, and form a space with the plane so that external air can enter the interior of the mounting housing 100 from the air inlet 120.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
