The a-frame is a shelf capable of carrying a plurality of pieces of glass so that the packaging apparatus can package the plurality of pieces of glass carried on the a-frame. Such as: referring to fig. 1 and 2, a base 41 of the a-frame 4 is provided with a bottom plate 42, a backup plate 43 and two side plates 44, the bottom plate 42 and the backup plate 43 are vertically connected, the two side plates 44 are respectively connected at two sides of the bottom plate 42 so that the bottom plate 42, the backup plate 43 and the two side plates 44 cooperate to form a containing concave portion for carrying glass, and when the glass is contained in the containing concave portion, the glass is attached to the backup plate 43 and abuts against the bottom plate 42 and the two side plates 44.

Since the packaging device has high requirements on the position accuracy of the plurality of pieces of glass on the a-frame 4, the position accuracy of the plurality of pieces of glass on the a-frame 4 is affected by the accuracy of the a-frame 4, and therefore, the position of the accommodating recess needs to be detected before the first piece of glass is placed on the a-frame 4. When the data of d1 and d2 are consistent with the design standard, the assembly precision of the A-shaped frame 4 is considered to meet the requirement, so that the position precision of a plurality of pieces of glass placed on the A-shaped frame 4 according to the placement requirement can also meet the requirement. It can be understood that the number of the side plates 44 on the a-frame 4 is two, so that whether the assembly accuracy of the a-frame 4 meets the requirement can be determined approximately by acquiring the data of d1 and d2 on the corresponding side of one side plate 44, or whether the assembly accuracy of the a-frame 4 meets the requirement can be determined more accurately by acquiring two sets of d1 and d2 on the corresponding sides of the two side plates 44.

However, when the measurement is performed on the outer side of the side plate 44, the position of the boundary line between the bottom plate 42 and the backup plate 43 cannot be determined on the outer side of the side plate 44 due to the presence of the side plate 44, and for this reason, the measurement needs to be performed after the side plate 44 is detached, resulting in low detection efficiency.

The edges of the first limiting structure 2 near the second surface 12 extend along a straight line, for example: as shown in fig. 4, the rib B extends along a straight line.

The second limiting structure 3 is connected to the second portion and extends away from the first portion, where the second limiting structure 3 may be elongated as shown in fig. 3 and 4, or may be other shapes. The edges of the second limiting structure 3 near the first surface 11 are flush with the edges of the first limiting structure 2 near the second surface 12, for example: referring to fig. 4, the edge of the second spacing structure 3 adjacent to the first surface 11 (i.e., edge a) is flush with the edge of the first spacing structure 2 adjacent to the second surface 12 (i.e., edge B).

The application method comprises the following steps: referring to fig. 5 and 6, the connecting structure 1 spans the side plate 44, the first limiting structure 2 is located at the inner side of the side plate 44, the edge B abuts against the junction between the plate 43 and the bottom plate 42, and then the values of d1 and d2 can be obtained by taking the edge a of the second limiting structure 3 located at the outer side of the side plate 44 as a reference and measuring through the cooperation of a ruler and a height ruler. It will be appreciated that the d1 and d2 data of the corresponding sides of the two side plates 44 can be acquired by turning over the auxiliary tool for detecting the assembly accuracy of the a-frame.

In the present embodiment, by using the auxiliary tool for detecting the assembly accuracy of the a-frame, the boundary line between the backup plate 43 and the bottom plate 42 can be extended to the outside of the side plate 44, whereby the values of d1 and d2 can be obtained without disassembling the side plate 44, and the assembly accuracy of the a-frame 4 can be determined, so that the detection efficiency can be improved.

Specifically, the plate body structure can be a plate cut from wood, a composite plate processed by raw materials with different shapes, or other plate body structures. The above-mentioned connection structure 1, first limit structure 2 and second limit structure 3 all are the plate body structure, connection structure 1, first limit structure 2 and the thickness direction of second limit structure 3 are unanimous, and connection structure 1, first limit structure 2 and the thickness of second limit structure 3 are unanimous, make the assistance utensil that is used for detecting A type frame assembly precision be lamellar structure, from this, after being used for detecting A type frame assembly precision the assistance utensil spanned curb plate 44, connection structure 1 and first limit structure 2 can laminate in backup plate 43, thereby can reduce the probability that is used for detecting A type frame assembly precision's assistance utensil to take place the aversion in the measurement process, in order to ensure measuring result's accuracy, and can use same raw and other materials to make connection structure 1 simultaneously, first limit structure 2 and second limit structure 3 in order to reduce the kind of raw and other materials, can make connection structure 1 through integrated into one piece's mode simultaneously, first limit structure 2 and second limit structure 3, in order to simplify the manufacturing technology, and make the structural strength of the assistance utensil that is used for detecting A type frame assembly precision made high.

In some embodiments, as shown in fig. 3 and 4, at least a portion of the surface of the second limiting structure 3 adjacent to the first surface 11 extending along the extending direction of the second limiting structure 3 is an inclined surface, such that an acute angle and an obtuse angle are respectively formed between the inclined surface and two surfaces of the second limiting structure 3 opposite to each other in the thickness direction, and the sum of the acute angle and the obtuse angle is 180 degrees. That is, the inclination direction of the inclined surface is inclined in the thickness direction of the second limit structure 3, instead of being inclined in the extending direction of the second limit structure 3.

When in use, after the auxiliary tool for detecting the assembly accuracy of the a-frame is erected on the side plate 44 of the a-frame 4, one side of the inclined surface (hereinafter referred to as a reference side) is on the same plane as the backup plate 43, and the angle between the plane on which the inclined surface is located and the surface of the backup plate 43 contacting the glass is an obtuse angle. And when the values of d1 and d2 are measured and acquired, the measurement is performed with the reference edge of the inclined surface as the reference line. Therefore, the probability of error of the detection result caused by the thickness of the auxiliary tool for detecting the assembly precision of the A-shaped frame can be reduced.

In some embodiments, the inclined surface of one auxiliary tool for detecting the a-frame assembly accuracy is opposite to the inclined surface of the other auxiliary tool for detecting the a-frame assembly accuracy so that the data of d1 and d2 of the sides corresponding to the two side plates 44 of the a-frame 4 can be acquired by the two auxiliary tools for detecting the a-frame assembly accuracy, respectively.

In some embodiments, the recess 13 is U-shaped and the outer profile of the connection structure 1 is U-shaped, see fig. 3 and 4. The U-shaped design allows the corners to be curved, thereby reducing the chance of scratching the a-frame 4 and/or surrounding glass during movement.

In some embodiments, as shown in fig. 3 and 4, the contour of the recess 13 is identical to the contour of the side plate 44, so that the portion of the connection structure 1 where the recess 13 is formed and the side plate 44 fit each other after the connection structure 1 straddles the side plate 44. This reduces the chance of displacement of the connecting structure 1 across the side plate 44 relative to the side plate 44, thereby making the result of the detection more accurate.

Thus, the auxiliaries for detecting the assembly accuracy of the a-frame can acquire data of d1 and d2 of the a-frame 4 corresponding to the side surfaces of the two side plates 44, respectively.

In some embodiments, referring to fig. 8 and 9, the second limiting structure 3 may include: the body 34 and the spacing piece 35, the body 34 is platelike structure and is unanimous with connection structure 1 thickness direction, and body 34 and second part are connected and are extended to the direction of keeping away from first part, and body 34 thickness direction has the third surface 341 and the fourth surface 342 that are opposite to each other, and spacing piece 35 can switch between connecting third surface 341 and fourth surface 342, and spacing piece 35 is connected the back with body 34, and spacing piece 35 is close to the first surface 11 the arris of being close to on the first limit structure 2 and is flush with the arris of second surface 12.

Specifically, the above-mentioned limit piece 35 can be switched between the third surface 341 or the fourth surface 342, and after the limit piece 35 is connected to the body 34, the edge of the limit piece 35 near the first surface 11 is flush with the edge of the first limit structure 2 near the second surface 12, that is, when the accuracy of the corresponding side of one side plate 44 is detected, the limit piece 35 can be connected to the third surface 341, and when the accuracy of the corresponding side of the other side plate 44 is detected, the limit piece 35 can be connected to the fourth surface 342.
