[0027] The utility model provides a high temperature resistance testing device for electronic components, which drives a lead screw to rotate through a motor, thereby driving a slider to slide in a slide groove of a heating box, thereby controlling the sliding of a placement plate, so that the placement plate can be slid out of the heating box during the testing process, thereby facilitating the observation of the electronic components on the placement plate.

[0028] Figure 1-Figure 4 The structure diagram of an embodiment of a high temperature resistance testing device for electronic components according to the present invention is shown in FIG. Figure 1-Figure 4 In this embodiment, a high temperature resistance detection device for electronic components includes a detection component 100 and a sliding component 200.

[0029] The detection assembly 100 includes a heating box 110, four bases 120 fixed at the lower end of the heating box 110, an operating table 130 arranged at the upper end of the heating box 110, and an opening and closing door 140 hinged at the front end of the heating box 110 by a hinge, a slide groove is provided inside the heating box 110, a plurality of heating wires are provided inside the heating box 110, and the heating wires are electrically connected to an external power supply through an external heating wire switch. Preferably, in this embodiment, the inner wall of the heating box 110 is provided with a heat preservation layer 111, and the heat preservation layer 111 arranged in the heating box 110 can keep the inside of the heating box 110 warm and reduce heat loss, and an observation window 141 is provided in the middle of the opening and closing door 140, and the observation window 141 arranged on the opening and closing door 140 is convenient for the operator to observe the inside of the heating box 110 through the observation window 141.

[0030] The sliding assembly 200 includes a motor 210 fixed to the lower side of the rear end of the heating box 110, a screw 220 fixed to the output end of the motor 210 and located in a slide groove, a slider 230 with threads arranged on the outside of the screw 220 and the outer wall fitting with the inner wall of the slide groove, and a placement plate 240 arranged at the upper end of the slider 230. Preferably, in the present embodiment, the bottom of the placement plate 240 is in contact with the top of the inner wall of the heating box 110, and the relative outer wall of the placement plate 240 is in contact with the relative inner wall of the heating box 110. The placement plate 240 in contact with the inner wall of the heating box 110 generates a certain friction force with the inner wall of the heating box 110 during sliding, thereby ensuring the stability of the placement plate 240 during sliding. A plurality of placement grooves 241 are provided at the upper end of the placement plate 240. The plurality of placement grooves 241 are evenly and equidistantly arranged on the placement plate 240.

During the testing process, the operator can observe the interior of the heating box 110 through the observation window 141 on the opening and closing door 140. If it is necessary to observe the electronic components, the operator opens the opening and closing door 140 and starts the motor 210. The motor 210 drives the lead screw 220 to rotate. The rotating lead screw 220 drives the slider 230 to slide, and then drives the placement plate 240 to slide like the front end, and slides the placement plate 240 to the outside of the heating box 110, so as to facilitate the observation of the electronic components on the placement plate 240 during the testing process. The placement plate 240 is clamped on the slider 230 under the action of the clamping groove 242, which is convenient for the operator to disassemble and replace the placement plate 240 in the later stage.
