[0004] Although the above-mentioned equipment can detect the thickness of the sheet, it is not convenient to quickly detect whether a large number of sheets are in place or whether there are sheets on the fixture. At the same time, the stability when positioning the sheet is also insufficient, which reduces the accuracy and efficiency of the equipment in detecting the sheet. Therefore, a sheet detection fixture with a through-beam detection function is urgently needed to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a sheet inspection fixture with a through-beam inspection function to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sheet inspection fixture with a through-beam detection function, comprising a support base for support, wherein the inner end surface of the support base is equidistantly provided with a plurality of positioning devices for positioning,

[0009] Preferably, the first sheet detection device includes a limiting clamping seat for support. Five groups of opposed photoelectric sensor transmitters are equidistantly arranged on the inner end face of the limiting clamping seat, and opposed photoelectric sensor receivers are arranged outside the limiting clamping seat opposite to the opposed photoelectric sensor transmitters.

[0010] Preferably, the positioning device includes a connecting column. Two clamping grooves are opened in the middle of the side end face of the connecting column, and a sheet positioning pin shaft is fixedly arranged at the center of the upper end face of the connecting column.

[0011] Preferably, the sheet alignment device includes a positioning clamping plate for limiting. A support block is arranged on the side end face of the positioning clamping plate, and an alignment clamping seat is fixedly arranged at the center of the side end face of the support block. A plurality of positioning holes are equidistantly opened near the outside of the upper end face of the alignment clamping seat.

[0012] Preferably, the alignment clamping seat is fixedly clamped with the sheet positioning pin shaft through the positioning hole. The sheet positioning pin shaft can quickly and accurately position and limit the sheet through the positioning hole, improving the convenience and stability of subsequent detection of the sheet.

[0013] Preferably, the sealing cover is fixedly connected to the upper end face of the limiting clamping seat, and a light hole corresponding to the limiting clamping seat is opened on the inner end face of the limiting clamping seat. The light hole can conveniently provide a sufficient guiding basis for the opposed photoelectric sensor transmitter to export light.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1-6 , an embodiment provided by the present utility model: A sheet detection fixture with an opposed detection function, including a support base 4 for support, and a plurality of groups of positioning devices 5 for positioning are equidistantly arranged on the inner end surface of the support base 4,

[0025] Sheet alignment devices 7, a plurality of groups of sheet alignment devices 7 are provided, and the sheet alignment devices 7 are equidistantly arranged on the upper end surface of the support base 4;

[0026] The upper end surface of the support base 4 is successively provided with a first sheet detection device 2, a second sheet detection device 3, and a third sheet detection device 6, and a sealing cover plate 1 for limiting is provided on the upper end surfaces of the first sheet detection device 2, the second sheet detection device 3, and the third sheet detection device 6.

[0027] The first sheet detection device 2 includes a limit card seat 22 for support. Five groups of opposed photoelectric sensor transmitters 21 are equidistantly arranged on the inner end face of the limit card seat 22. An opposed photoelectric sensor receiver 23 is arranged outside the limit card seat 22 and opposite to the opposed photoelectric sensor transmitter 21.

[0028] The positioning device 5 includes a connecting column 53. Two groups of clamping grooves 52 are opened in the middle of the side end face of the connecting column 53. And a sheet positioning pin shaft 51 is fixedly arranged at the center of the upper end face of the connecting column 53.

[0029] The sheet alignment device 7 includes a positioning card plate 71 for limiting. A support block 72 is arranged on the side end face of the positioning card plate 71. And an alignment card seat 73 is fixedly arranged at the center of the side end face of the support block 72. A plurality of positioning holes 74 are equidistantly opened near the outside of the upper end face of the alignment card seat 73.

[0030] The alignment card seat 73 is fixedly clamped with the sheet positioning pin shaft 51 through the positioning holes 74. The sheet positioning pin shaft 51 can quickly and accurately position and limit the sheet through the positioning holes 74, improving the convenience and stability of subsequent sheet detection.

[0031] The sealing cover plate 1 is fixedly connected to the upper end face of the limit card seat 22. And a light hole corresponding to the limit card seat 22 is opened in the inner end face of the limit card seat 22. The light hole can facilitate the opposed photoelectric sensor transmitter 21 in the subsequent process to provide a sufficient guiding basis for light emission.

[0032] Working principle: During use, the staff can batch import the sheets to the upper part of the sheet alignment device 7 through an external sheet loading module. During positioning, the sheet positioning pin shaft 51 can pass through the positioning holes 74 to the outside of the alignment card seat 73, thereby limiting and positioning the end of the sheet. When detecting whether the sheet is in place and present, the opposed photoelectric sensor transmitters 21 inside the first sheet detection device 2, the second sheet detection device 3, and the third sheet detection device 6 can emit opposed detection light. At this time, the opposed photoelectric sensor receiver 23 located at the middle detection position can receive the light source emitted by the opposed photoelectric sensor transmitter 21. Since a slit is provided at the receiving end of the opposed photoelectric sensor receiver 23, the opposed photoelectric sensor receiver 23 can sense a sheet with a thickness of 0.2 mm and can also sense whether the sheet is in place. If the sheet is not in place or is misaligned, the opposed photoelectric sensor receiver 23 is blocked and cannot receive the light source. At this time, the opposed photoelectric sensor receiver 23 can activate an external warning device for warning.

[0033] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
