Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of preventing hot plug, specifically relates to a jig structure for preventing hot plug. BACKGROUND

[0002] In the LCM (liquid crystal display display module) module picture inspection station, the operator needs to connect the LCM module signal line + power line and then carry out picture related detection, and needs to remove the related wire after the detection is completed to carry out the next operation. In this operation, due to the need to call multiple programs for detection, the contents of detection of different models are different, and the wire CT requirement, the staff cannot avoid the situation that the test is just completed, the power line is not removed, and the circuit is still under the condition of live working, the function module part is directly inserted or pulled out, which causes damage to the LCM module and the circuit of the detection instrument, resulting in high subsequent repair cost or flowing into the market. SUMMARY

[0003] The utility model aims at overcoming the insufficient prior art, and provides a jig structure for preventing hot plug.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] The jig structure for preventing hot plug comprises a jig main body, a support bottom plate is arranged at the front end of the jig main body, a support backstop is arranged at the back of the support bottom plate, the bottom of the to-be-detected part is supported on the support bottom plate, and the back of the to-be-detected part abuts against the support backstop; an infrared sensor is arranged on the side surface of the support backstop, the infrared sensor emits an infrared signal to detect the to-be-detected part, and the infrared sensor detects the to-be-detected part when the back of the to-be-detected part abuts against the support backstop; when the to-be-detected part lies on the support bottom plate, the infrared sensor does not detect the to-be-detected part, and the detection signal transmitted in the signal line connected with the to-be-detected part is cut off.

[0006] Further, the support backstop comprises a connecting sleeve and a stop rod, a sliding cavity matched with the stop rod is arranged in the connecting sleeve, the stop rod is in sliding fit with the sliding cavity and is locked by a screw to adjust the height of the stop rod.

[0007] Further, the upper end of the stop rod is provided with a rubber block.

[0008] The utility model discloses the above technical scheme has the beneficial effect of: infrared inductor detects the to-be-detected piece on the detection fixture, when the personnel put the to-be-detected piece on the fixture main body after the test inspection is completed, infrared inductor does not detect the to-be-detected piece, infrared inductor detects the to-be-detected piece from yes to no instant, and the control system stops the detection signal output of signal line immediately, and this response time is about 0.1 seconds, which is far lower than the time of personnel pulling the line, thereby ensuring that the personnel cut off the output before pulling the line, not causing hot plug, and effectively avoiding the badness of the to-be-detected piece (such as LCM module) caused by hot plug. The utility model discloses strong compatibility, is suitable for all the stations of preventing hot plug detection, has very strong foolproofness, and improves the automation level of detection station. BRIEF DESCRIPTION OF DRAWINGS

[0009] The utility model discloses further detailed below in combination with the drawings and specific embodiment:

[0010] Fig. 1 It is the side view of the utility model normal detection time;

[0011] Fig. 2 It is the side view of the utility model detection completion, and the to-be-detected piece is down. SPECIFIC EMBODIMENT

[0012] As shown in Figs. 1-2 The utility model discloses a fixture structure of preventing hot plug, including fixture main body 1, the front end of fixture main body 1 is equipped with support base plate 2, the back of support base plate 2 is equipped with two interval arrangement's support back stop 3, and the bottom of to-be-detected piece 5 is supported on support base plate 2, and the back of to-be-detected piece 5 is supported on support back stop 3. Support back stop 3 adopts the design of height adjustable, specifically, support back stop 3 includes connecting sleeve 31 and stop lever 32, and the inside of connecting sleeve is equipped with the sliding cavity that is matched with stop lever 32, and stop lever 32 is slidably connected with the sliding cavity and is locked by screw to adjust the height of stop lever 32. The upper end of stop lever 32 is equipped with rubber block 33 and is used to abut to-be-detected piece 5.

[0013] The side of support back stop 3 is equipped with infrared inductor 4, and infrared inductor 4 is arranged at the close vertical angle with support back stop 3. Infrared inductor 4 emits infrared signal and detects to-be-detected piece 5, and when the back of to-be-detected piece 5 is supported on support back stop 3, infrared inductor 4 detects to-be-detected piece 5, and when to-be-detected piece 5 is put on support base plate 2, infrared inductor 4 does not detect to-be-detected piece 5, and the detection signal transmission in the signal line connected with to-be-detected piece 5 is cut off.

[0014] The utility model discloses a working principle: detection, personnel place the detection piece 5 (LCM module) on fixture, the back of detection piece 5 leans on the support back stop 3 at this moment, personnel connect signal line and connect power supply to detection piece 5, infrared inductor 4 detects detection piece 5, and detection signal continues output. When testing inspection is completed, infrared inductor 4 just detects detection piece 5 when personnel detection piece 5 is placed on fixture main body 1, infrared inductor 4 detects detection piece 5 from has to no instant, and control system immediately stops signal line's detection signal (detection signal contains the voltage Vcc, GNG that provides stable work to product and figure signal) output, this response time is about 0.1 seconds, far lower than the time of personnel to pull out the line, thereby ensuring that personnel disconnects output before pulling out the line, does not cause hot plug, effectively avoids the bad of detection piece 5 due to hot plug.

[0015] The above describes the specific embodiment of the utility model, but the person skilled in the art should understand that this is only an example, and the person skilled in the art can make various changes or modifications to this embodiment without departing from the principles and essence of the utility model, but these changes and modifications all fall within the protection scope of the utility model.
