[0002] In the existing full-automatic tensile testing machine, the sample holder is usually matched in the system, and the tester needs to carry the sample to the side of the sample holder. The capacity of the sample holder is limited. After all the samples on the sample holder are stretched, the tester needs to manually place the samples to be tested on the sample holder. Since the placement time is relatively long, the equipment needs to be stopped, the automation level of the whole process is low, the work efficiency is low, and the labor intensity of the tester is large.

[0003] To improve the automation level of the equipment and reduce the labor intensity of the tester, an AGV automatic transfer module is added to the full-automatic tensile testing machine matching system. The tester places the samples on the customized sample tray, and the AGV transfers the sample tray to the full-automatic tensile testing machine. Correspondingly, the matching system of the full-automatic tensile testing machine is equipped with a tray support frame at the specified position, and the AGV places the sample tray on the tray support frame. Compared with the manual sample placement method of the tester in the prior art, the AGV carrying the sample tray to transfer the sample can reduce the labor intensity of the tester and has a high automation level.

[0004] However, it is found in actual use that since the precision of the mechanical hand grabbing in the full-automatic tensile testing machine is relatively high and is a pre-set program, the placement position of the sample tray has high requirements, but the current tray support frame is only a general support table, which cannot guarantee that the sample tray is accurately placed at the specified position and cannot meet the grabbing requirements of the mechanical hand.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It should be known by those skilled in the art that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0033] The principles and spirits of the present application will be explained in detail below with reference to several representative embodiments of the present application.

[0034] The embodiments of the sample tray device for AGV automatic handling provided by the present application are as follows:

[0035] As shown in Figures 1 to 5 , the sample tray device for AGV automatic handling (hereinafter referred to as sample tray device) comprises a tray support frame 100 and a sample tray 200. The sample tray 200 is brought to the tray support frame 100 by the AGV when in use, and the AGV positions and places the sample tray 200 on the tray support frame 100.

[0036] The structure of the tray support frame 100 is as shown in Figures 2 to 4 . The tray support frame 100 comprises a frame structure 101, which comprises two stands 102 and a connecting frame 103 connecting the two stands 102. The two stands 102 are parallel to each other. For the convenience of description, the direction of the interval between the two stands 102 is defined as the first horizontal direction, and the direction perpendicular to the first horizontal direction is defined as the second horizontal direction. As shown in Figure 2 , in the second horizontal direction, the connecting frame 103 is located at one end of the stand 102; due to the interval between the two stands 102, a horizontal opening 104 is formed between the two stands 102, and the AGV can pass through the horizontal opening 104 to enter directly below the frame structure 101.

[0037] Here, both the stand 102 and the connecting frame 103 are frame structures composed of columns, cross braces, etc.

[0038] As shown in Figure 2As shown, the frame structure 101 further comprises positioning bars 106 fixed at the top of each stand 102, and the positioning bars 106 are arranged along the second direction. As shown Figure 4 As shown, the positioning bar 106 has a horizontally arranged supporting surface 105, and the supporting surface 105 is used to support the sample tray 200. The positioning bar 106 is further provided with a guide slope 110, and the guide slopes 110 of the two positioning bars 106 are arranged downward and upward and away from each other. The purpose of arranging the guide slope 110 on the positioning bar 106 is to limit the position of the sample tray 200 in the first horizontal direction.

[0039] As shown Figure 2 and Figure 4 As shown, the supporting surface 105 of the positioning bar 106 is fixedly installed with a buffer device 107, and the buffer device 107 is a hydraulic buffer. In other embodiments, the buffer device 107 can be a spring buffer device, a gas buffer, etc. The function of the buffer device 107 is to buffer the sample tray 200 when the sample tray 200 falls on the supporting surface 105.

[0040] Two buffer devices 107 are installed on each positioning bar 106, and the two buffer devices 107 are arranged in the second horizontal direction.

[0041] As shown Figure 2 and Figure 3 As shown, two V-shaped grooves 108 are provided on each positioning bar 106, and the V-shaped grooves 108 extend along the first horizontal direction. Here, the V-shaped grooves 108 extend through the positioning bar 106 along the first horizontal direction. The positioning bar 106 is further provided with a rectangular groove 109 below the V-shaped groove 108, and similarly, the rectangular groove 109 extends along the first horizontal direction. Here, the rectangular groove 109 extends through the positioning bar 106 along the first horizontal direction. The size of the rectangular groove 109 in the second horizontal direction is consistent with the size of the bottom of the V-shaped groove 108 in the second horizontal direction.

[0042] The V-shaped grooves 108 on the two positioning bars 106 are arranged opposite to each other in the first horizontal direction.

[0043] The structure of the sample tray 200 is as shown Figure 5As shown, the sample tray 200 is an open-top box. Two scale rulers 201 are fixed on the sample tray 200, and the two scale rulers 201 are arranged in a second horizontal direction and each extends in a first horizontal direction. Two sample positioning plates 202 are slidingly arranged on the scale rulers 201, and the sample positioning plates 202 are strip-shaped plates extending in the second horizontal direction and arranged in the first horizontal direction. Specifically, a sliding groove is formed at the bottom of the sample positioning plate 202, and the size of the sliding groove is matched with the size of the scale ruler 201, so that the sample positioning plate 202 can slide and will not tilt. By sliding at least one sample positioning plate 202, the distance between the two sample positioning plates 202 can be changed to adapt to samples of different lengths. The scale ruler 201 is provided with a scale, which can be used as a reference, and the tester can roughly place the sample on the sample tray 200 through the scale ruler 201.

[0044] The sample positioning plate 202 is provided with a plurality of sample positioning grooves 203, and the sample positioning grooves 203 are arranged in the second horizontal direction. The shape of the sample positioning groove 203 is determined according to the shape of the sample 300. For example, when the sample 300 is a plate, the sample positioning groove 203 is a rectangular groove; when the sample 300 is a rod, the sample positioning groove 203 is a V-shaped groove.

[0045] In the first horizontal direction, two groups of rollers 204 are arranged on both sides of the sample tray 200, and the two groups of rollers 204 on the same side are arranged in the second horizontal direction. Each group of rollers 204 includes two rollers 204, and the two rollers 204 in the same group are arranged in the second horizontal direction. In order to install the rollers 204, mounting blocks 205 are arranged on the inner side of the sample tray 200, and the roller shafts of the rollers 204 pass through the sample tray 200 and are threadedly connected to the mounting blocks 205.

[0046] In the second horizontal direction, the space occupied by the two rollers 204 in the same group is matched with the size of the rectangular groove 109. Here, the matching means that when the two rollers 204 enter the rectangular groove 109, the rollers 204 can be blocked by the rectangular groove 109, so as to realize positioning.

[0047] In use, the sample tray 200 holds the sample 300, the AGV vehicle carries the sample tray 200 and moves to the tray support frame 100, the AGV vehicle enters the frame structure 101 through the horizontal opening 104, at this time, in the first horizontal direction, the sample tray 200 basically corresponds to the two supporting surfaces 105; in the second horizontal direction, the rollers 204 on the sample tray 200 basically correspond to the V-shaped grooves 108. Then the sample tray 200 is lowered, and in the lowering process, the two guide inclined surfaces 110 guide the sample tray 200 to fine-tune in the first horizontal direction, so that the sample tray 200 can be reliably placed on the supporting surface 105; in the second horizontal direction, the V-shaped grooves 108 fine-tune the sample tray 200, so that the rollers 204 fall into the rectangular grooves 109.

[0048] In this embodiment, the positioning strip constitutes the frame positioning member for positioning the sample tray. In other embodiments, the supporting surface at the top of the frame structure can be the top surface of the stand, and the frame positioning member only has a guide inclined surface, only playing a role of guiding the sample tray.

[0049] The scale ruler 201 plays a role of guiding the sliding of the sample positioning plate 202, and the scale ruler 201 is a guide rail in this embodiment. In other embodiments, a general guide rail can be used instead of the scale ruler.

[0050] In this embodiment, the positions of the two sample positioning plates 202 are adjustable, so that the distance between the two sample positioning plates 202 can be adjusted. In other embodiments, only one of the two sample positioning plates 202 is adjustable, and the distance between the two sample positioning plates 202 can also be changed. In other embodiments, the two sample positioning plates 202 are fixedly arranged, and the distance between the two sample positioning plates 202 is not adjustable, but for samples of a fixed length, they can also be used.

[0051] In this embodiment, the tray positioning member is two rollers rotatably installed on the sample tray. In other embodiments, the tray positioning member is a positioning block fixed on the sample tray.

[0052] In this embodiment, the frame structure includes two stands and a connecting frame connecting the two stands, and the two stands have a horizontal opening therebetween. In other embodiments, the frame structure includes four columns, and the top of each of the four columns is provided with a positioning block, and a horizontal opening is formed between any two adjacent columns; the four columns are divided into two groups arranged at intervals along the first horizontal direction, and the positioning blocks on each group of columns form a frame positioning member together.

[0053] In this embodiment, the frame positioning member is provided with a V-shaped groove and a rectangular groove. In other embodiments, only the V-shaped groove can be retained.
