At present, in the corner detection of a notebook computer D shell, the following process is generally adopted, an object to be detected is placed on a detection table, all sides of the object to be detected are required to be aligned with corresponding positions of a detection tool, then the corner part is manually measured, then the detection tool is manually checked, whether the corner size of the object to be detected meets the product requirement or not is judged based on whether an iron piece at the bottom of the detection tool is exposed or not. Because the D shell can wrap up in its corner position when detecting has soft cloth, can coat on the soft cloth has the corner oil, often appears the D shell and examine a relevant position under the effect of corner oil during the measurement, leads to unable normal detection, and then influences detection efficiency.

In order to alleviate the above-mentioned problems and obtain a higher efficiency of detection results, embodiments of the present disclosure provide an inspection jig, referring to fig. 1 and 2, the inspection jig 10 includes: the object stage 11, the sensor 13, the indicator light and the controller, wherein the object stage 11 is provided with a limiting member, the limiting member is used for limiting the boundary positions of the first side A, the second side B and the third side C, an inlet for inserting an object to be detected is formed on the fourth side D, and the first side A, the second side B, the third side C and the fourth side D jointly form a containing space for containing the object to be detected; the sensor 13 is provided with a detection light source, the detection light source is naked on one surface of the object stage 11 close to the object to be detected, the detection light source is arranged at the corner position between the fourth side D and the first side A, or the detection light source is arranged at the corner position between the fourth side D and the third side C; the indicator light is used for displaying whether the test passes or fails; the controller is connected with the sensor 13 and the indicator lamp respectively, the sensor 13 sends an electric signal whether the light source is covered to the controller, and the controller controls the on-off of the indicator lamp according to the electric signal.

The sensor 13 may be, for example, a photosensor, a color sensor, a proximity sensor, or the like.

Illustratively, the surface of the stage 11 in the embodiment of the present disclosure matches the surface structure of the object to be measured that is in contact with the surface of the object to be measured, the surface of the stage 11 may be a smooth plane, or the surface of the stage 11 may be provided with a structure such as a protrusion or a groove that matches the object to be measured.

Illustratively, the limiting member of the embodiments of the present disclosure may be a single structure, and the limiting member may define a receiving space for receiving the object to be measured together with the surface of the stage 11. Alternatively, the spacing member may be a combination of a plurality of separate structures located on the first side a, the second side B, and the third side C, respectively.

With the inspection jig 10 of the embodiment of the present disclosure, a limiting member is disposed on the stage 11, and the limiting member can define boundary positions of the first side a, the second side B, and the third side C, which can prevent the object to be inspected from sliding out of the stage 11, and the sensor 13 has a detection light source, and a set position of the detection light source can be used to define a size specification range of the inspection. For example, the object to be measured is inserted into the accommodating space defined by the limiting member and the stage 11 from the fourth side D, when the object to be measured covers at least part of the detection light sources, the sensor 13 can sense the existence of the cover, and sends a signal covered by the sensor 13 to the controller, and the controller controls the corresponding indicator lights to be turned on according to the judgment conditions, so as to give an automatic inspection result. The whole process of the inspection jig 10 disclosed by the disclosure is simple to operate, the object to be inspected does not need to be manually aligned to each side of the object to be inspected, the inspection efficiency is accelerated, the object to be inspected does not slide out of the object stage 11, and the inspection jig is more suitable for the inspection step of automatic production.

The detection light source based on the sensor 13 can be set into different shapes according to actual application scenes.

Specifically, the detection light source of the sensor 13 integrally forms any one of a rounded corner, a chamfer or a right angle structure. That is, according to the different inspection requirements, the inspection jig 10 of the embodiment of the disclosure can be used to inspect whether the fillet, chamfer, right angle, etc. of the object to be inspected meet the dimensional tolerance requirements.

For example, the inspection fixture 10 of the embodiment of the present disclosure takes as an example whether the size of the fillet meets the size tolerance requirement, the detection light source of the sensor 13 may be a fixed structure boundary, or the detection light source of the sensor 13 may also be a range between two fixed structure boundaries. This enables adaptation to more scenarios for checking corner dimensional specifications.

The embodiments of the present disclosure take as an example whether the fillet size meets the boundary range interval, and further detail the present scheme.

For example, two sensors 13 may be provided, a first sensor 131 and a second sensor 132 disposed at an equidistant interval from the first sensor 131, with the equidistant dimension therebetween being included in the inspection tolerance range.

Depending on the inspection criteria, the range of spacing between the first sensor 131 and the second sensor 132 may be a portion of the inspection tolerance range value range, or the range of spacing between the first sensor 131 and the second sensor 132 may be one of the intermediate or boundary values of the inspection tolerance range value range. This allows adapting to the requirements of different precision dimension tests.

Taking the inspection tool 10 of the embodiment of the disclosure for detecting a wider size range as an example, the setting positions of the first sensor 131 and the second sensor 132 may be respectively selected from the boundary values of the inspection tolerance range values.

Specifically, with further reference to fig. 3, the verified tolerance range includes an upper limit and a lower limit, one of the first sensor 131 and the second sensor 132 being located at the upper limit position, and the other of the two being located at the lower limit position.

For example, when the standard tolerance range of the dimensional tolerance of the D-shell fillet to be detected is (+0.3 mm, -0.1 mm), the positions of the first sensor 131 and the second sensor 132 are located on (x, y), where x ranges from (x+0.15 mm, x-0.15 mm), y ranges from (y+0.05 mm, y-0.05 mm), so as to obtain the upper limit position (x-0.15 mm, y-0.05 mm), and the lower limit position (x+0.15 mm, y+0.05 mm), so as to obtain the set positions of the first sensor 131 and the second sensor 132, further referring to fig. 3, the position of the first sensor 131 is the lower limit position, and the position of the second sensor 132 is the upper limit position.

In order to further realize the direct display of the automatic detection fillet results.

Specifically, the pilot lamps are provided with two, and two pilot lamps indicate different colour light sources respectively.

For example, one of the indicator lights may be used to display blue, and may be used to represent that the test is acceptable, and the judgment condition may be that the object to be tested covers the detection light source of the second sensor 132, but does not cover the detection light source of the first sensor 131.

For example, another indicator light may be used to display red color, and may be used to represent that the inspection is failed, where the judging condition may not be that the object to be inspected covers the detecting light sources of the first sensor 131 and the second sensor 132 at the same time, or that the object to be inspected does not cover the detecting light sources of the first sensor 131 and the second sensor 132 at the same time, and in both cases, the fillet sizes of the object to be inspected at the time are failed.

For convenience of description and understanding of the following embodiments, the first direction is illustratively defined as the thickness direction of the stage 11, the second direction is defined as the width direction of the stage 11, and the direction in which the object to be measured is inserted into the stage 11 is defined as the length direction of the stage 11.

Further, the stop member includes a plurality of stop members 12, and with further reference to FIG. 4, each stop member 12 has a first top surface 121 for limiting movement of the test object out of the stage 11 in a first direction and a first side A surface 122 for limiting movement of the test object out of the stage 11 in a second direction.

For example, the first top surface 121 may be formed on an extended structure of the limiting member 12.

For example, the first side a surface 122 may be formed on another extension of the stopper 12.

Illustratively, the first top surface 121 and the first side a surface 122 are each spaced apart from the edge of the object to be measured by a safe tolerance. The safety tolerance interval may be determined according to actual process requirements, and may be any value between 0.05mm and 0.1mm, or may be 0.05mm or 0.1mm, for example.

Further, the inspection tool 10 of the embodiment of the disclosure further includes a workbench 15, the controller may be mounted on the workbench 15, the stage 11 may be fixed on one surface of the workbench 15, the indicator may be exposed on one surface of the workbench 15, and the sensor 13 passes through the stage 11 and is connected with the workbench 15.

Specifically, the inspection fixture 10 further includes a plurality of positioning columns 16, where each positioning column 16 passes through the stage 11 and is connected to the workbench 15, and each positioning column 16 is disposed on a side of each limiting member 12 far away from the object to be inspected. This enables a stable inspection environment to be formed.

Specifically, the stage 11, the positioning column 16, and the stopper 12 all adopt insulating structures.

Illustratively, the stage 11 may employ a film.

For example, the positioning posts 16 and the limiting members 12 may be rubber structures.

For example, the table 15 may be a wood structure having a relatively hard hardness such as a skid, or the table 15 may be a stainless steel plate structure having a relatively high structural strength.

To sum up, taking an object to be tested as a notebook computer D case as an example, the inspection procedure operation steps of the inspection tool 10 in the embodiment of the disclosure will be described in detail: firstly, inserting a D shell into a containing space formed by each limiting piece 12 and the object stage 11 along the fourth side D, starting a controller switch when the D shell reaches the boundary position of the second side B, simultaneously electrifying the first sensor 131 and the second sensor 132, and controlling a blue indicator lamp to be lightened by the controller when the detection lamp source of the second sensor 132 is shielded and the detection lamp source of the first sensor 131 is not shielded, wherein the verification result is PASS; when the detection light sources of the two sensors 13 are blocked, or the detection light sources of the two sensors 13 are not blocked, the controller controls the red indicator light to be on, and at this time, the verification result is NG.
